Description

[Detailed description of the invention] This invention is designed to prevent grains from being mixed in when the grains are sequentially conveyed into a large number of dryers or storage tanks using a movable supply conveyor body that can reciprocate in the left and right direction. The present invention relates to a dust removal device in a grain drying facility or grain storage facility that prevents dust from being scattered into a workplace from the discharge side end of a movable supply conveyor main body, resulting in an unsanitary condition.

Conventionally, a large number of dryers or storage tanks are installed in a workplace, and a fixed supply conveyor main body and a movable supply conveyor main body that can reciprocate in the left and right direction are sequentially arranged three-dimensionally above the dryers or storage tanks. It is well known that there are drying facilities and storage facilities in which grains are carried into an arbitrary dryer or storage tank by stacking movable supply conveyors and moving back and forth from side to side, and drying or storing grains is carried out at any time. It is being

By the way, the grains carried into the dryer or storage tank contain a lot of dust, so when the grains are carried into the dryer or storage tank by the movable supply conveyor body, there is a lot of dust mixed in with the grains. Dust is scattered into the workplace from the discharge end of the movable supply conveyor main body, resulting in unsanitary conditions and a significant reduction in work efficiency.Therefore, there is a strong desire to improve this problem.

In view of the above, the present invention is based on a supply source that has drop ports on both the left and right sides of a movable supply conveyor body that is disposed at the top of a large number of dryers or storage tanks so that it can move back and forth in the left and right direction. At the same time, one end of the dust suction pipe is connected to the above-mentioned supply source with an open connection, and a lot of dust that is about to be scattered into the workplace from the discharge side end position of the movable supply conveyor main body during carrying-in work is removed through the dust suction pipe. Is it acceptable to forcibly suck dust and improve the sanitary environment in the workplace?
The purpose is to provide a dust removal device for grain drying facilities or grain storage facilities that can improve work efficiency. Let's discuss an example.

Reference numeral 1 denotes a suitable work room, and in the work room 1 there are a number of dryers capable of drying grains or a number of storage tanks 2 capable of storing grains for a predetermined period of time without spoiling. They are arranged in parallel, and each of the dryers or storage tanks 2 is provided with a supply hopper 3 having an open upper surface above the dryer or storage tank 2, respectively.

A self-feeding device 4 is installed above the multiple dryers or storage tanks 2 installed in parallel to transport the grains to the dryers or storage tanks 2 at desired positions.

As is clear from FIG. 1, the self-conveying supply device 4 has a fixed supply conveyor main body 7 whose supply side is connected to an elevator 6 installed vertically in a pit 5 dug in the workshop 1.
The guide rail 9 is mounted via rotating rollers 13 on a guide rail 9 which is located at the bottom of the fixed supply conveyor main body 7 and installed at the top of the attached dryer or storage tank 2. It consists of a movable conveyor main body 8 that can be moved back and forth in the left and right directions at any time. Supply pipes 11 each having a drop port 12 are attached to the left and right sides of the conveyor body 8, respectively.

Reference numeral 14 denotes a belt suspended within the fixed supply conveyor main body 7 so as to rotate only in one direction.

One end of the dust suction pipe 16 is connected to the suction exhaust fan 15, 15, and the other end of the dust suction pipe 16 is connected to the upper surface of the left and right supply pipes 11゜11 formed as described above.
Due to the negative pressure action of the supply pipe 11, the dust filled in the supply pipe 11 is quickly sucked up, and the dust is concentratedly discharged to the outside of the working chamber 1 as appropriate.

The dust suction pipe 16 is suspended by a hanging wire 17 and a hanging band 18, and is formed so as to be able to expand and contract when the movable supply conveyor main body 8 moves back and forth from side to side.

Next, the operation of the present invention will be explained.

Now, as shown in the figure, after grains are put into the pit 5, if they are continuously supplied to the supply side of the fixed supply conveyor main body 7 by the elevator 6, the grains are conveyed by the rotating belt 14 and moved from the end to the lower stage. It is dropped and fed onto a belt 10 suspended within the main body 8 of the type feed conveyor.

However, the belt 10 is rotated to the left in FIG.
is on the supply hopper 3 of the dryer or storage tank 2 in the first row, and the drop port 12 of the supply pipe 11 located on the right side is on the supply hopper 3 of the dryer or storage tank 2 in the fourth row. Therefore, the grains conveyed by the belt 10 pass through the supply pipe 11 and the drop port 12 to the supply hopper 3 of the first row.
The liquid is supplied by falling into the dryer or storage tank 2.

By the way, during the carrying-in work as described above, the suction exhaust fan 15 on the grain carrying side is operated and the supply pipe 1 is passed through the dust suction pipe 16.
Since the interior of the work chamber 1 is under negative pressure, much of the dust that has scattered inside the supply pipe 11 is quickly sucked up through the dust suction pipe 16 and concentratedly discharged outside the work chamber 1.

Therefore, during the work of transporting grains to the dryer or storage tank 2, there is no dust scattered from the discharge side end position of the movable supply conveyor main body 8, and the transport work can be carried out efficiently under sanitary conditions. be able to.

Furthermore, when the work of transporting the grains to the dryer or storage tank 2 is completed on the first evening, the belt 10 can be rotated clockwise in the state shown in Fig. 1, and at the same time the suction fan 15 on the right side can be started. Similarly, the work of carrying grain into the dryer or storage tank 2 on the fourth day of the first day can be efficiently accomplished under sanitary environmental conditions.

By moving the movable supply conveyor main body 8 along the guide rail 9, grains can be accurately transported to the dryer or storage tank 2 of the second and third stages.

In short, since the present invention has the above-mentioned specific configuration, it is possible to supply a large number of installed dryers or storage tanks 2 via a fixed supply conveyor body 7 and a movable supply conveyor body 8 that can reciprocate in the left and right direction. All the dust that is about to be scattered into the workplace 1 from the discharge side end position of the movable supply conveyor main body 8 during the work of transporting grains is accurately and quickly sucked up by the negative pressure action from the dust suction pipe 16, The dust collection position was set inside the supply pipe 11 having the drop port 12 in order to centrally exhaust the dust outside the work room 1 and thereby enable the grain transport work to be carried out efficiently in a sanitary environment. The separation and suction effect of dust mixed in grains can be further improved.
