Description

[Detailed description of the invention] This invention is a dust generation prevention device that completely prevents free dust generation during storage in a device that stores dusty substances such as calcined ore, thereby providing an excellent working environment. Regarding equipment.

For example, when calcined ore is temporarily stored for necessity, it is transported from a predetermined location to the target storage tank via a conveyor, and in this case, a fairly large amount is rapidly transported and supplied to increase storage efficiency. It is customary to configure it as follows.

However, it is common practice for the storage tank that accommodates these to have its entire upper surface open, or to have only the part where the input conveyor runs on its own open to the band 4jζ1]. Therefore, since the upper surface of tank C is open at that point other than the part corresponding to charging, dust generated due to charging C2 spreads onto the tank through this area, and this is suppressed]; Because no measures had been taken to prevent this, it was allowed to spread freely, severely damaging the working environment in the area.

This idea was devised to solve the above problem, and its purpose is to completely prevent free dust generation during storage, thereby providing an excellent working environment. The device is disclosed, and its characteristics are as follows: a pair of storage tanks are arranged in parallel on the left and right, and each row is divided internally in the front-rear direction; There is a reversible feeding near 7 conveyor that can move forward and backward so that both ends of the conveyor stop correspondingly on each tank, and the tip of the conveyor is synchronized with the feeding conveyor to constantly supply dust onto the feeding conveyor. A storage device equipped with a feeding conveyor that moves in a vertical direction, and a plurality of storage tank upper surface input ports provided corresponding to the stepwise stop positions of the input conveyor, and a tank other than the top surface input ports. Intermediate dust introduction guide ports are provided at opening/closing dampers that are opened by dust particles and are opened at positions corresponding to both ends of the input conveyor on the top surface, and a dust collection port that sucks negative pressure from the inside of the storage tank; A dust collection hood that communicates with the dust collection port is provided, and the upper surface of the tank is closed as much as possible, and the outer periphery of the input conveyor including the feeding conveyor is surrounded by a cover, and the lower end opening of the cover is It is located at the point where it communicates with the input port.

The specific examples shown in the drawings will be described below.

As shown in FIGS. 1 to 6, the storage tanks 1 are arranged in four rows in the vertical direction and are arranged in pairs on the left and right to form a band-shaped opening.

In this way, the upper surface of each storage tank 1 is closed with a clay wall plate 2 so as to cover the entire surface as much as possible, leaving each opening described below.

That is, one of the openings constitutes a completely open upper surface input port 3 of the storage tank, which is inserted through the center of each of the storage tanks 1, and the target calcined ore is supplied to each of the storage tanks while stopping in stages. be done.

In this case, as shown in FIGS. 3, 5, and 6, the inlet 3
An integrated hopper 4 for use is provided in a fitted manner on the upper wall plate 2, and this constitutes the upper surface input port 3.

Note that 5 and 5 are vertical and horizontal support frames.

Reference numeral 6 denotes another opening, which is an intermediate dust introduction guide port formed in the longitudinal direction before and after each input port 3.

As shown in FIG. 4, this guide port 6 has an inclined wall 7 to cope with the force on the bottom side of the port 6, and is constructed by installing an opening/closing damper 8 made of a rubber plate in the horizontal direction of the inclined wall 7. has been done.

The damper 8 is opened only by the weight of the dust generated and normally remains closed, and therefore cannot be called a completely open opening.

A dust collection port 9 has one end attached to the earth wall plate 2 so as to communicate with each tank 1. The dust collection port 9 sucks negative pressure inside the tank via a dust collection duct damper 10 and a dust collector, and forcefully collects the dust through the dust collection hood 11. The dust is done.

12 is a feeding conveyor, 13 is a charging conveyor, and the leading end of the feeding conveyor 12 is configured to move forward and backward along the left and right upper side of the storage tank 1 as shown in the first figure, and from the transfer conveyor 14 at the rear end. The dust-generated materials are conveyed in an upwardly sloping manner and are dropped from the tip onto a horizontally oriented input conveyor 13.

The input conveyor 13 operates together with the feeding conveyor 12 with both ends thereof corresponding to the input port 3, and in this case, a cover with a rubber tube at the lower end is used to cover the input conveyor 13 from the tip of the feeding conveyor 12. 15, and this lower end opening is configured to communicate with the input port 3.

Further, the input conveyor 13 is of a reversible type so that it can alternately supply the left and right input ports 3, 3.

Note that 15 is a guide rail for both conveyors 12 and 13 for self-propelled movement.

Therefore, in the above configuration, dust such as calcined ore is transferred by the feeding conveyor 12, and is further dropped from the tip to the input conveyor 13, thereby being distributed to the left and right. As shown in Figure 3, storage begins when both ends of the input conveyor 13 correspond to the input ports 3 of the first stage.

In this case, everything from the feeding conveyor 12 to the storage tank 1 is covered and the waste is processed through this, so that no dust is generated and the waste is stored without mistakes using the cover 15 as a guide.

At the same time, the inside of the closed tank 1 is made negative pressure by suction through the dust collection port 9, and this suction force collects dust not only inside the tank but also inside the cover 15, so that there is no leakage to the outside.
Moreover, since the opening/closing damper 8 itself closes the introduction guide port 6 with the elasticity of rubber, dust can be collected efficiently.

On the other hand, when the input is finished, the flow moves to the next input port 3, but in this case, continuous supply is made even in the middle of the process, and the introduction guide port 6 receives the input and passes through the inclined wall 7. Furthermore, the dust particles themselves are stored by pushing open/closing damper 8 open.

Dust is still being collected here, so no dust is generated from the input port 3, and even if the opening/closing damper 8 is opened, no dust will leak from here, and dust generated in the introduction guide port 6 can also be sucked. It is possible.

This invention is as described above, and therefore, with the above configuration,
Free dust generation during storage was completely prevented, resulting in an extremely excellent working environment outside the tank.

Due to the above structure acid, dust particles can be fed without worrying about dust generation, so it is possible to feed and store these dust particles in large quantities and rapidly, so that the storage can be efficiently disposed of. .

Furthermore, with the above configuration, dust collection is performed in a completely closed state when supplying to the inlet that generates the most dust, and dust collection can be carried out efficiently for a long time, allowing processing without significant power loss. .
