Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous separation and storage device used in a system for transporting solid materials such as garbage and grains by air current.

In such systems, the solids are transported together with the gas, so the gas and solids are separated at the end, and if the gas is air, they are released to the atmosphere, and the solids are collected in a storage tank and then disposed of. Is it necessary to perform some processing?

In order to perform separation and storage as described in F, conventionally, the first
! A device like the one shown in Figure 4 is required.

In these figures, 1 is a cyclone type separator, 2 is an inlet for a mixed flow, 3 is an outlet for gas, and a storage tank 5 is connected to the lower end via a connection 4.

The storage tank 5 is a horizontal rotating type in the example shown in Fig. 1, and a vertically fixed type in the examples shown in Figs. There are various types, such as the flange type shown in Figure 3 and the conveyor type shown in Figure 4.

Furthermore, there are various types of lids 6 provided at the discharge ports of each storage tank 5.

However, in both of the above cases, since the cyclone separator 1 is placed above the storage tank 5, the total height becomes very large. - may have to be penetrated,
There is a risk that various problems related to Architecture-F may occur.

Furthermore, since it is necessary to assemble on-site, the cost of on-site construction increases, and work at heights increases the risk. Furthermore, since it is installed at a high place, a large mount is also required.
Therefore, as the overall weight increases, the price also increases.

The purpose of the present invention is to overcome the drawbacks of conventional separation and storage devices as described above.

That is, the present invention incorporates a cyclone separator in the rear part of a horizontal rotating storage tank, and collects the solids separated in the separator and discharged from the opening at the bottom by scraping the inner periphery of the rear part of the storage tank. The present invention provides a continuous separation and storage device for solids that is scraped up by upper blades and discharged into a storage tank through chutes at the top and both sides of the separator.

1 to 8, reference numeral 11 denotes a cyclone separator, which is fixed to a support frame 13 provided at the rear of a base 12. In FIGS.

14 is a horizontal rotating storage tank, and the rear part of this tank 14 covers the separator 11 as shown in FIG.
It is rotatably supported therein via a bearing 15. Further, a tire 16 is fixed around the entire circumference of the tank 14 near the front part, and this tire 16 is supported by a pair of rollers 17 on both sides of the upper front end of the base 12. Alternatively, both may be driven by a drive device such as a motor or a speed reducer (not shown) to rotate the storage tank 14 in the direction of the θ-th arrow.

An inlet 18 for a mixed flow of gas and solids is provided on the outside of the upper part of the separator 11, and an outlet 19 for the separated gas is provided at the upper end of the separator 11.
6 It is directed towards the rear like fR+. Further, a solid material discharge port 20 is provided at the lower end of the separator 11 as shown in FIGS. 6 and 8.

Reference numeral 21 denotes a plurality of blades fixed to the inner periphery of the rear end of the storage tank 14, which have an L cross section as shown in FIGS. 7 and 8.

Further, on the left and right outer sides of the separator 11, as shown in FIG. An arc-shaped guide plate 23 is provided along the inside of the scraping blade 21 to prevent the solids scraped up by the blade 21 from falling to the rear side of the chute 22.

Furthermore, the bent portion 2 of the outlet 19 protrudes from the upper end of the separator 11.
3'' is provided with protrusions 1 to 24 and 25 that slope forward on both sides as shown in FIG. from the chutes 24, 25 on both sides and the front into the storage tank 14 at the front.

The front portion of the storage tank 14 has a tapered shape with a narrowed front portion as shown in FIG. 6, and this portion protrudes forward from within the frame 26 at the front end of the base 12Φ.

Reference numeral 27 denotes a lid for opening and closing the discharge port at the front end of the storage tank 14, and this lid 27 is attached to an arm 29 that is swingably attached to the frame 26 with a shaft 28.
The arm 29 is rotatably attached to the end of the arm 29, and the arm 29 is driven by hydraulic pressure or an air cylinder. Further, when the lid 27 closes the outlet of the storage tank 14, the rotation center of the lid 27 becomes concentric with the rotation center of the tank 14, and rotates together.

Note that one or more spiral blades 30 are provided in the storage tank 14 so that the solids in the tank 14 are sent forward as the tank 14 rotates.

The device of this invention has the above-mentioned configuration, and an example of its use will be explained below.

In FIG. 5, solid matter such as garbage that is generated irregularly is transported by a conveyor 31 and stored in a primary storage tank 32. When this tank 32 is full, a rotary feeder 33 starts rotating and is transported by air current. When the system is activated, the device of the present invention is also activated and the storage tank 14 begins to rotate.

Therefore, the solids transported along with the gas in the transport pipe 34 flow tangentially from the goods 18 into the separator 11, so that the solids and gas are separated in the separator 11. The solids rotate as indicated by the arrows in FIG. 5, and while rotating along the inner surface of the peripheral wall of the separator 11 due to centrifugal force, the solids are separated from the gas, descend, and are discharged from the discharge port 20 at the bottom.

On the other hand, an exhaust pipe 36 having a secondary filter 35 is connected to the outlet 19 as shown in FIG. The gas separated from the substances flows out from the outlet 19, fine dust in the gas is removed by the filter 35, and if the purified gas is air, it is discharged into the atmosphere by the blower 37.

On the other hand, the solid matter discharged from the discharge port 20 is
It is raked up by the raking blade 21 in the storage tank 14, which is rotating in the direction of the arrow in the figure.

In this way, the solid matter scraped up by the blades 21 rises along the guide plate 23, but along the way, the solid matter is raised by the chute 22.
When the solid material comes out upward, it crumbles onto the chute 22 and slides down on the chute 22 to the position of the spiral blade 30.

In addition, the solids that did not spill out on the way move to the upper part of the separator 11 and fall down, slide down on the chute 24, 25, fall on the chute 22 or on the 3° part of the spiral blade, and finally All the solids are sent forward into the storage tank 14 by the spiral blades 30 that rotate together with the storage tank 14.

As a result of the above action, the solids in the storage tank 14 become full or if the operation continues thereafter, the solids are further compressed and stored.

When the solids are sufficiently compressed and stored in the storage tank 14 in this way, all operations are stopped, the lid 27 is opened, and only the storage tank 14 is rotated. This solid material is discharged from the discharge port at the front end, and the solid material is transferred to the transportation vehicle 3B as shown in Fig. 5.
Load the i-C and transport it to the desired location.

As described above, the device of this invention includes a cyclone separator 11 that separates solids transported together with a gas such as air from the gas by centrifugal action, and a horizontal rotary storage tank 1.
Since it is installed in the rear part of Figure 4, Figures 1 to 4
A separation storage tank that is extremely small and lightweight compared to the conventional device shown in the figure is obtained.

In addition, the present invention not only combines the cyclone separator 11 and the horizontal storage tank 14, but also provides scraping blades 21 on the inner periphery of the rear part of the storage tank 14, thereby increasing the discharge port 20.
The solids discharged from the separator 11 are scraped up, and the solids thus scraped are disposed of on both sides and upper shoes of the separator 11).
2.2, 24.25, all solids are dropped into the storage tank 14 before the separator 11, so the solids separated in the separator 11 are smoothly and continuously filled and stored in the storage tank 14. As a result, the separation and storage of solids transported in gas can be carried out extremely efficiently.
