The axial bottom end extends along the axial line of the closed tank body (1) to the appropriate height to terminate. The volume formed between the axial bottom end of the inner tube (6) and the lower end plate of the closed tank body (1) corresponds to the water weight + the closed tank body (1) has a structural weight greater than that of the closed tank body (1) The volume of the compressed air (10) is completely extruded corresponding to the buoyancy, so that the airtight The body (1) does not cause the condition of the closed tank body (1) to float when the submerged mud pumping operation; the liquid bottom mud (19) is guided to guide the liquid bottom mud (19) to be displaced upward in the closed tank body (1). And blocking the compressed air (25) to break through the short surface of the liquid surface to discharge the closed tank body (1), and the mud inner pipe (6) is connected to the mud discharging pipe (20) to guide the sediment to the destination point; the intake and exhaust pipe group Connected to the air inlet pipe (5) of the upper end plate of the tank body (1), and the air intake valve (7) and the exhaust valve (8) are arranged between the intake and exhaust pipe group to be ventilated tee (9) and The air inlet pipe (5) is connected to guide the compressed air into and out of the sealed tank body (1), wherein the exhaust valve (8) is used for discharging the compressed air (10) in the closed tank body (1), and the intake valve ( 7) It is used to guide the compressed air (10) to extrude the high concentration sediment in the tank body (1). When the air pumping submerged mud is used, the intake and exhaust pipe group does not follow the sealed tank body (1) Sink into the water body, and the water is installed on the mud pump (15); the upper end plate of the closed tank body (1) is welded with the lifting point, and the crane (16) on the mud pump (15) pumps the air. It is hoisted vertically into a lake or ocean to remove high concentrations of sediment deposited on the bottom of the lake.

The method and device for delivering high-concentration bottom sediment with compressed air as shown in Figures 2, 3, 4, 5, 6, 7, 8, and 9 include a closed tank (1) submerged step, row The gas entering step and the air intake step. When the present invention is used for removing sediments (19) in deep water areas such as lakes and oceans, the first step is to perform a submerged tank (1) submerged step, and the crane (16) on the dredger (15) will close the trough ( 1) Vertically hoist, so that the vertical liquid of the mud pipe (2) is slowly moved into the water. First, the intake valve (7) is closed, the exhaust valve (8) is opened, and the clear water (18) in the lake is filled into the tank (1) In the middle, the closed tank body (1) closes the exhaust valve (8) and stops the water body into the tank. The mud pipe (2) penetrates the bottom mud layer (19) at the bottom of the lake and stops the tank body. The intake valve (7) is opened, and the compressed air (10) is introduced into the tank body (1). The liquid in the tank is subjected to the positive pressure of the compressed air (10). The self-discharging check valve (4) is pressed out of the mud. The tube (20) is discharged from the sealed tank body (1), and is blocked by the feed check valve (4), so that the liquid in the tank cannot flow back to the lake according to the mud pipe (2), and the liquid sent to the destination point is rejected by the discharge material. The blockage of the valve (4) cannot be reversed back into the tank (1), and the continuous pressurization of the compressed air (10) continuously discharges the liquid in the tank, and the liquid level in the tank drops to the axial direction of the inner tube (6) of the mud. At the edge, the blockage of the compressed air (10) without liquid level will directly penetrate the inner tube (6). Stop the liquid in the tank and discharge it into the closed tank body (1); then enter the exhaust gas into the mud step, at this time the intake valve (7) closes the exhaust valve (8) to open the compressed air in the tank (10) to circulate the air pipe (5) And the exhaust valve (8) escapes into the atmosphere, and when the pressure in the tank is lower than the water pressure around the closed tank body (1), the sediment (19) is forced into the closed tank body according to the mud pipe (4) ( 1) Inside, when the bottom mud inflow reaches the rated time, close the exhaust valve (8) to stop the sludge from flowing into the closed tank (1); then enter the intake sludge step, and the intake valve (7) opens the compressed air (10) Injection into the tank body (1), the liquid in the tank is subjected to the positive pressure of the compressed air (10). The self-discharging check valve (4) is pressed out of the draining pipe (20) to discharge the sealed tank body (1). The blocking of the check valve (4) prevents the bottom mud in the tank from flowing back to the lake through the mud pipe (2), and the liquid sent to the destination point is blocked by the discharge check valve (4) and cannot be returned to the tank (1) Continuously pressurizing the compressed air (10) to continuously discharge the liquid in the tank to lower the liquid level in the tank, and to close the intake valve (7) after the sludge is discharged to the rated time, and then enter the exhaust gas into the mud step, and then fill the bottom mud into the airtight seal. Tank (1), stepping into the mud and stepping in the air These two steps are alternately operated to continuously remove the sediment; in the process of sediment extraction, the crane (16) can be used to horizontally move the closed tank (1) to make the probe (2) fall into the sediment (19) at any time. Displacement, the bottom mud of the area through which the mud pipe (2) passes is removed, and the method of instantaneous and large-area sediment removal is achieved.

As shown in Figures 2, 3, 4, 5, 6, 7, 8, and 9, the high-concentration sediment is a method and apparatus for delivering sediment to compressed air, and when the bottom mud is sent, the closed tank body (the closed tank body ( 1) In the deep water area, the pressure around the tank body is equal to the water pressure. When the compressed air (10) in the closed tank body (1) is gradually emptied, the pressure difference between the inside and the outside of the closed tank body (1) will gradually increase. The pressure difference is greater than the maximum flow resistance of the sediment in the sediment layer (19). The sediment will be squeezed into the closed tank (1) in the original sludge concentration state, and the mud (1) of the closed tank (1) There is no rotating element that can catch the debris in the sediment layer (19). As long as it can flow into the bottom of the closed tank (1), the sealed tank (1) can be extruded by compressed air (10). The allowable range of debris in the sediment is wide; when the sediment is sent, the compressed air (10) in the tank is much lower than the sediment in the tank (19), so it is naturally suspended in the tank (19). Above, as the compressed air (10) continues to be injected into the closed tank (1), the bottom mud (19) is naturally replaced by compressed air in the tank and is extruded into the closed tank (1). 19) The highest it can be reached when it is squeezed out The process is the injection pressure of the compressed air (25). The minimum pressure of the compressed air (10) needs to be greater than the water pressure of the closed tank (1) and the flow pressure of the sediment (19) in the drain pipe (20). When the liquid level in the tank drops to the bottom end of the axial lower edge of the inner pipe (6), the compressed air (10) that does not have the inner bottom mud will directly penetrate the inner pipe (6), the groove The residual bottom mud can no longer be pressed out of the closed tank body (1). At this time, the compressed air is injected into the sealed tank body (1), and the exhaust valve (8) is opened to depressurize the compressed air in the closed tank body (1). The pressure difference between the inside and outside of the gutter reaches the rated value, and the bottom mud (19) around the tank is squeezed into the tank. When the sediment is injected to the rated time, the liquid level reaches the predetermined upper limit, and the compressed air (10) is refilled. The bottom mud in the tank is pressed to the target point, so that the high-concentration sediment (19) at the bottom of the lake is sent in batch mode, and the discharge check valve (4) above the tank is responsible for avoiding mud discharge during the sediment feeding process. The inner bottom mud of the tube (20) is countercurrently flowed back into the closed tank body (1) when the tank is subjected to the exhaust gas pressure relief mud-in step, and the feed check valve (3) prevents the inner bottom of the tank from being subjected to the air intake mud discharge operation. Mud pressurized by compressed air Feeding check valve (3) and the soil pipe probe (2) flowing out of the sealed tank (1) into the lake outside the groove by.

As shown in Figures 2, 3, 4, 5, 6, 7, 8, and 9, the high-concentration sediment is sent by compressed air, and the closed tank body (1) is used when the bottom mud is sent. The mud pipe (2) placed in the deep water is completely immersed in the sediment layer (19), and the sediment is forced into the closed tank body by the water pressure (1), even if the sediment concentration is high to be colloidal, the positive pressure can be applied. Forced to squeeze into the closed tank (1), because the mud pipe (2) is inserted into the sediment layer (19) at any time, so the clear water around the tank (18) will not flow into the closed tank by the sediment layer (19). 1) Therefore, the sediment (19) sent by the sludge has the highest sludge concentration near the bottom of the lake; and there are no rotating elements in the mud pipe (2) and the closed tank (1), so it will not get stuck. The debris in the sediment layer (19) can be forced to be squeezed by the compressed air (10) to the destination point as long as the mud (19) flowing into the mud pipe (2) is high. The amount of impurities contained in the bottom mud is wide and the proper rate is high. The compressed air (10) injected into the closed tank body (1) can be adjusted arbitrarily to adjust the head of the sediment output synchronously. Unlike the conventional pumping pump, the pumping head is fixed, and if the sludge concentration of the pumping object is too high, The flow resistance of the thick mud is fixed. The lift can not increase the lift. Accelerating the flow of the thick mud will reduce the efficiency of sludge removal. It is necessary to add water to reduce the concentration and improve the fluidity so that the pumping operation can continue to operate. The sludge has a relatively high water content, which makes the sediment removal efficiency low, and the high-speed rotating components in the pump easily catch the debris in the sediment layer to reduce or lose the pumping efficiency, so that the proper rate is lowered. . When the water depth is deeper, the pressure difference of the bottom mud layer (19) squeezed into the closed tank body (1) is larger, so the higher the concentration that the bottom mud can be squeezed, the better the sputum delivery effect is as long as The bottom mud which can flow into the closed tank body (1) can be sent to the target point by the compressed air (10), and the bottom mud which can be transported is widely distributed, and is a new type of submerged mud pump which is relatively stable, inexpensive and reliable. Pu.

As shown in Figures 2, 3, 4, 5, 6, 7, 8, and 9, the high-concentration sediment is sent by compressed air, and the mode of the sediment-carrying operation is batch type. A continuous pumping of the sediment requires a double-slot air pumping unit. The method and device for sending a double-slot high-concentration sediment as shown in Figs. 10 and 11 by compressed air, which are provided with two mutually independent first circulation grooves (22) and second circulation grooves (23), each cycle The tanks (22) and (23) are each an independently operable air pump, wherein the respective drain pipes (20) are connected to each other into a single line, and between the drain pipe (20) and the circulation tank (22) (23). The discharge check valve (4) is connected, and the intake valves (24) (26) of the upper exhaust pipe group are connected in series to the air source, and the first circulation groove (22) and the first one are independent of each other. The two circulating grooves (23) are integrally fixed to each other, and the more the number of the series of the independent air pumping circulating grooves (22) (23), the groove exchange pressure is sent during the switching of the tank body. The pressure pulse phenomenon of the drain pipe (20) caused by the moment of the bottom mud will be lower. The higher the number of the serially connected circulation grooves, the higher the pulse pressure phenomenon of the drain pipe (20), and the higher the stability of fluid transport. .

The method and apparatus for delivering a double-slot high-concentration sediment as shown in Figs. 10 and 11 by compressed air, including the initial sludge introduction step, alternately circulating the sludge discharge step. When the method performs the bottom mud picking operation, first enters the initial feeding step, and the exhaust valve (25) (27) on the two circulating tanks (22) (23) is opened to make the internal pressure of the closed tank body (1) and the atmosphere Isobaric, the bottom mud (19) around the mud pipe (2) is squeezed into the circulation tank (22) (23) by the water pressure pipe (2) and the feed check valve (3). After the liquid rises to the rated time, close the exhaust valve (25) (27) so that the pressure in the tank is the same as the water pressure around the probe (2), so that the sediment (19) stops flowing into the circulation tank (22) (23). Then enter the alternating cycle discharging step; when performing the alternating cycle discharging step, the discharging operation of the first circulating tank (22) is first performed, and the intake valve (24) of the first circulating tank (22) is opened to guide the compressed air ( 10) Into the tank, press the high-concentration sediment in the tank downward through the mud inner tube (6), the discharge check valve (4) and the drain pipe (20) to the destination point. When the position drops to the rated value or rated time, close the intake valve (24) to stop the discharge of the first circulation tank, perform the intake discharge operation of the second circulation tank (23), and open the second circulation tank intake valve. (26) guiding the compressed air (10) into the second circulation tank (23) to press the sludge in the tank downward The pilot mud inner tube (6), the discharge check valve (4) and the mud discharge pipe (20) are guided to the destination point; while the second circulation groove (23) is discharged, the first circulation groove (22) Performing the venting step, the exhaust valve (25) of the first circulation tank (22) opens the pilot sludge (19) and is injected into the first circulation tank (22). When the liquid level in the tank reaches the rated value or rated time Close the exhaust valve (25) to stand by. When the liquid level of the second circulating tank (23) drops to the rated value or rated time, close the intake valve (26), and then enter the first circulating tank (22). Step, the first circulating tank intake valve (24) opens and injects compressed air (10) to pump the sludge in the tank to the destination point, so that the two circulating tanks (22) (23) are alternately operated alternately to continuously deliver the sludge. To the purpose of the point.

In summary, the method and apparatus for delivering high-concentration sediment of the present invention by compressed air have the following characteristics:

(One). The concentration of the bottom sediment is the highest: the air pumped mud pipe (2) of the present invention penetrates into the bottom mud layer (19) of the deep water area, and the bottom mud is forced into the closed tank body (1) by the water pressure, so that the bottom is muddy. The bottom sludge has a maximum sludge concentration close to the bottom mud layer. No traditional sinking pump faces the poor fluidity. The bottom mud needs to be diluted by adding water to remove the sludge. The concentration of the sludge is low and the sludge pumping efficiency is poor. The situation occurs, so there is the highest pumping efficiency and the lowest energy consumption.

(two). The range of allowable debris in the sediment is wide: there is no rotating element in the air pump, which minimizes the probability of getting stuck in the sediment. As long as it can flow through the bottom of the mud pipe (2), it can be compressed. The air (10) is pumped to the destination, which is a wide range of products that are relatively stable and reliable.

The above-mentioned high-concentration sediment is a method and a device for sending compressed air, which is placed in deep water, and the water pressure is pumped around the air to force the bottom mud into the air pump and the compressed air is used to deliver the sediment to the use. At the point, the mud concentration is high, and the sediment is allowed to have a wide range of impurities, which is a practical and economical pumping device.

The innovative concept of the invention can overcome the lack of conventional devices, and the high concentration of mud can allow the passage of large particle size in the mud, which is an invention with practicality and innovation, and the application is made according to law, and the review committee of the member can be reviewed, and As soon as possible, the patent of this case is prayed.
