Description

[Detailed description of the invention] [Field of industrial application] This invention uses a transfer pump to discharge snow brought in by dump trucks, snowplows, or snow shooters into rivers, swamps, etc. together with water. Regarding snow removal equipment.

[Conventional technology]

In snowy regions, snow from roads and snow taken off roofs is loaded into dump trucks and dumped into vacant lots or relatively large rivers.

[The problem that the idea attempts to solve]

However, when snow that has accumulated on the ground is removed and transported by dump truck, etc., a large amount of dirt, gravel, or coarse garbage (hereinafter referred to as "earth and sand, etc.") from the ground is often mixed in with the transport. When the snow ages and disappears, it remains unsightly in snow dumping grounds, spoiling the aesthetics, and in rivers, it settles and raises the riverbed.

The present invention has been made in view of the above, and an object of the present invention is to provide snow removal equipment that can eliminate the above-mentioned obstacles caused by earth and sand.

[Means to solve the problem]

In order to achieve the above object, the present invention has a crushing pit equipped with a snow discharge tube at the bottom and housing an auger that is rotated by a required drive device, which receives snow thrown from a dump truck etc. A pressure water pump sends water to a snow crushing device connected to a chute, and an outer cylinder that has a snow suction port connected to the discharge pipe of the snow crushing device and is connected to a transfer pipe. a transfer pump equipped with an injection nozzle that injects snow toward the transfer pipe, sucks snow from the suction port, and sends the snow from the suction portion to the transfer pipe; and the water sent through the transfer pipe of the transfer pump. It is equipped with a settling basin that receives snow and sediment, settles the soil, etc. mixed in with it, and releases the water and snow into rivers, etc.

[Effect]

While operating the pressure water pump to inject water from the injection nozzle toward the transfer pipe, the auger of the snow crusher is rotated to finely crush the snow and discharge it into the discharge pipe. The snow discharged into the discharge tube is sucked into the transfer pipe from the suction port through the suction part, and is transferred to the settling pond by the transfer pipe by water jetted from the injection nozzle. At this time, the earth and sand mixed with the snow,
It is carried along with the snow to the settling basin and settles at the bottom of the basin. Water and snow that have settled sediment in the settling basin will be released directly into rivers, etc. The sediment settled on the bottom of the settling basin is scraped out from the settling basin as necessary.

The snow crushing device 1 includes a snow discharge tube 5 on the bottom 4a, a crushing pit 4 that houses an auger 6 that is rotationally driven by a required drive device (not shown), and The chute 9 is connected by a hinge 7 and has a vertical inclination angle adjustable by a vertical means 8 such as a cylinder. Note that the discharge tube 5 has its mouth edge 5a curved along the rotating surface of the crushing blade of the auger 6, and its mouth edge 5a slightly protrudes above the bottom surface 4a of the crushing pit 4 (about several centimeters to 10 cm). It is designed to work together with the auger 6 to crush snow masses.

The transfer pump 2 is constructed as follows. That is, the reference numeral 11 designates an outer cylinder, which has a snow suction port 11a at the upper center and an air intake pipe 12 at the right end in FIG. An injection nozzle 13 is attached to the right end of the outer cylinder 11 in FIG. 2 and opens into the outer cylinder 11.
Further, between the injection nozzle 13 and the suction port 11a in the outer cylinder 11, a jet flow protection pipe 14 is connected to an air intake port 11b communicating with the air intake pipe 12.
is formed between the bracket 1 and the injection nozzle 13.
5, and a transfer pipe 16 is inserted into the left end of the outer cylinder 11 in FIG. A flange 17 provided on the outer peripheral surface of the outer cylinder 11 is connected to a flange 18 provided at the end of the outer cylinder 11 with bolts and nuts (not shown) in a fluid-tight manner.

The jet nozzle 13 sprays water into the jet protection tube 14.
It is a device that injects forcefully toward the outer cylinder 11.
It consists of a pipe fitting 19 fixed to the pipe fitting 19, and a nozzle body 20 detachably inserted into the pipe fitting 19. In addition, the jet flow protection pipe 14 is connected to the jet nozzle 1.
Air intake port 11b by water injected from 3
The jet flow is surrounded by air sucked in from the jet flow, and the jet flow is guided to the transfer pipe 16 without reducing the velocity while keeping the shape at the time of jetting. Furthermore, the transfer pipe 16 is for transferring the jet stream and the snow sucked in by the jet stream to the sand settling basin 3.

Note that the injection nozzle 13 and the injection flow protection tube 1
4 and the transfer tube 16 (more precisely, the portion of the transfer tube 16 inserted into the outer tube 11) are provided so that their central axes coincide with each other and are concentric with the outer tube 11.

The central part of the outer cylinder 11, that is, the suction part 11c
A pair of left and right jet nozzles 21 are provided below. This jet nozzle 21 injects water into the suction port 1.
1a, and like the injection nozzle 13, it consists of a pipe fitting 22 and a nozzle body 23 that is detachably inserted into the pipe fitting 22, and protects the jet stream from the injection nozzle 13. The structure is such that water is ejected into the suction port 11a while avoiding the passage T of water that is injected into the transfer pipe 16 through the pipe 14.

The suction port 11a of the transfer pump 2 is connected to a flange 2 at the lower end of the discharge tube 5 of the snow crushing device 1.

is provided, and is configured to suck water that does not contain snow from the lower part of the sand settling basin 3 from a communication path 35 and circulate it to the tank 30 through a water pipe 36.

Reference numeral 37 is a water intake pipe whose opening degree can be freely adjusted by a water intake amount control valve 38, and is connected directly to an appropriate water source or via a water intake pump (not shown).
It is possible to supply water to the water distribution well 31 from the water intake source as needed.

Next, the operation of the present invention configured as described above will be explained.

The snow S is transported by a dump truck or the like and thrown into a chute 9, and the drive device is started to rotate the auger 6. The snow mass S thrown into the chute 9 slides down along the bottom plate of the chute 9 and hits the auger 6. The auger 6 receives the snow mass S and scrapes it by a predetermined amount to crush it into small pieces. Note that normally, when dumping snow into the chute 9 using a dump truck or the like, the chute 9 is kept in a substantially horizontal state by the vertical means 8, and then the chute 9 is tilted at an appropriate angle by the vertical means 8. When the snow quality is hard, the slope of the chute 9 is made gentle by the vertical means 8 to slow down the sending of the snowpack S to the auger 6.On the other hand, when the snow quality is soft, the chute 9 is slowed down. Increase the tilt angle. The auger 6 of the crushing pit 4 thus crushes the snowpack while moving it to the discharge tube 5, and finally works with the mouth rim 5a of the discharge tube 5 to further crush the snowpack S into finer pieces and transfers it to the discharge tube 5. let it fall.

The snow discharged into the discharge tube 5 is immediately sucked into the suction port 11a of the transfer pump 2 by the suction action of the water injected from the injection nozzle 13 and its own weight, and together with the water that is vigorously injected from the injection nozzle 13. The sand is then sent to the sand settling basin 3 through the transfer pipe 16.
At this time, the water ejected from the ejection nozzle 21 prevents snow from adhering to the inner surface of the suction port 11a,
To smoothly suck snow into the suction part 11c. The snow thus sucked into the transfer pipe 16 comes into contact with the jet water and is further pulverized into fine particles, with a considerable amount of the snow being melted. The amount of water jetted from the jet nozzle 13 and the jet nozzle 21 is adjusted by adjusting the flow rate adjustment valves 28 and 29.

Sediment, etc. mixed with the snow is completely separated from the snow by crushing, making it finer, and melting the snow, and is transported to the settling basin 3 together with the snow and water. It settles to the bottom 3a. Sediment, etc. to settling pond 3
The snow and water settled on the bottom 3a of the settling basin 3
b, flows through the spillway 33, and is sent to rivers and the sea. The water pump 34 sucks water that does not contain snow, sediment, etc. from the sand settling basin 3 through the communication path 35,
The water is circulated to the tank 30 through the water pipe 36.
If necessary, the water intake amount control valve 38 is opened to supply water to the diversion well 31.

Other embodiments and technical matters other than those described above will be described below.

(1) The water supply pump 34 can be omitted by installing the pressure water pump 25 in the water distribution well 31.

(2) In the one shown in FIG. 1, the injection nozzle 13 and the injection nozzle 21 are connected to one pressure water pump 25 via a connection pipe 26 and a branch pipe 27, but two pressure water pumps may be connected individually.

(3) It goes without saying that the higher the temperature of the water injected from the injection nozzle 13, the better, but it will work even at a minimum of 0 to 3 degrees Celsius, so if relatively high temperature water is supplied from the water intake source, the water temperature Water intake can be conserved by restricting the intake amount using the water intake amount control valve 38 so that the temperature is about 0 to 3°C. Therefore, quantitative constraints on water sources are relaxed and a variety of water sources can be applied.

(4) Treated sewage water maintains a temperature of 5 to 10 degrees Celsius even in winter, so if the amount is sufficient, a high snow melting effect can be obtained, and if the amount is small, it becomes possible to remove snow using the water-saving method described above.

(5) In addition to the above, it is possible to use factory wastewater, mineral spring wastewater, irrigation canals, rivers, seawater, groundwater, etc., so the location requirements for snow removal equipment are relaxed.
You can consider a wide range of locations. Therefore, snow removal and snow removal are facilitated, and the use of the settling basin 3 allows for free consideration of the destination of the snow.

(6) The structure of settling basin 3 will be designed to suit the location conditions.
It is possible to use an unexcavated pond, reinforced concrete construction, steel plate construction, etc., and the entire facility can be constructed either temporarily or permanently.

(7) When installing the tank 30, the water intake pipe 37
It is also possible to contact the tank 30 directly.

(8) The partition wall 32 is intended to prevent fine snowflakes in the settling basin 3 from flowing into the diversion well 31.
Although it depends on the region, the height usually needs to be about 50 to 80 cm. Further, the height of the communicating path 35 is required to be about 50 to 80 cm, although it depends on the thickness of the earth and sand collected at the bottom 3a of the sand settling basin 3.

(9) In order to efficiently discharge the snowflakes floating on the surface layer of the settling basin 3, the upstream end of the snow pipe should be opened on the downstream side of the partition wall 32 (on the left side in Figure 1) and the snow flakes floating on the surface layer of the settling basin 3 should be opened. It is recommended to set it in

Water sent from a pressure water pump is connected to a snow crushing device installed in the snow crushing device and an outer cylinder that has a snow suction port connected to the discharge pipe of the snow crushing device and is connected to a transfer pipe. Inject toward the transfer pipe,
A transfer pump equipped with an injection nozzle that sucks snow from the suction port and sends it from the suction portion to the transfer pipe, and earth and sand that receives water and snow sent through the transfer pipe of the transfer pump and is mixed therein. The snowpack is equipped with a settling basin that releases water and snow into rivers, etc. The snowpack is crushed by a crushing device and sent to a transfer pump, and the water is vigorously jetted from an injection nozzle into the settling basin. Since the structure is configured to transfer, it is possible to accurately separate earth and sand that has been mixed into and integrated into the snow mass from the snow and settle it in the settling basin during the transfer. Therefore, soil and sand will not remain in snow dumping areas such as parks and vacant lots in early spring and spoil the aesthetic appearance, nor will it sink to the bottom of rivers and raise the riverbed.
