Description

Technical Field

[0001] This utility model relates to the field of coal bunker management technology, specifically a coal bunker management device with a collapse protection function. Background Technology

[0002] Materials in a coal storage silo are transported directly into the silo via a material conveyor. The falling material compresses the air inside the silo, creating a high-pressure upward airflow. This upward airflow encounters and impacts the falling material, breaking it apart from its continuous flow. Due to the impact and friction between the high-pressure gas and the falling material, a high concentration of coal dust and heat accumulates inside the coal storage silo, increasing the risk of coal dust explosions. To reduce the coal dust concentration inside the silo and mitigate safety hazards, a coal storage silo control device with collapse protection function is provided. Utility Model Content

An extension rod is fixedly installed on the right side of the limit block, and the extension rod is slidably connected to the coal storage bin. A second spring is fixedly installed on the side of the extension rod near the limit block. The end of the extension rod away from the second spring is fixed to the coal storage bin. The elasticity of the second spring is used to reset the limiting block and the extension rod. The bottom of the coal storage bin has a discharge port, and a discharge plate is provided on the discharge port. The discharge plate is hinged to the coal storage bin. A limiting rod is provided at the bottom of the discharge plate to limit the discharge plate. The end of the limiting rod away from the discharge plate is fixed to the connecting plate. The connecting plate is slidably connected to the coal storage bin. A connecting rod is fixedly installed on the top of the connecting plate and is slidably connected to the coal storage bin.

[0011] Compared with the prior art, this utility model provides a coal bunker control device with a collapse protection function, which has the following beneficial effects:

[0012] 1. This coal bunker control device with collapse protection function is equipped with a discharge mechanism. When the work is finished, the air pump is turned off, the filter plate is pulled to release the limit on the extension rod, the spring returns and drives the extension rod and the limit block to reset, releasing the limit on the inclined plate. The spring returns and the left end of the inclined plate resets, shaking the coal dust remaining on the inclined plate and letting it fall into the discharge port through the inclined surface. When the filter plate is pulled, the limit on the connecting rod is released, and the connecting rod drives the connecting plate to descend. When the limit rod descends, the limit on the discharge plate is released, and the discharge plate rotates downward. The coal dust falls from the discharge port into the collection box, improving work efficiency, preventing coal dust backflow, and reducing safety hazards.

[0013] 2. This coal storage control device with collapse protection function is equipped with a filtration mechanism. Raw materials are fed into the coal storage bin through the feed pipe. The motor is started to drive the rotating rod. The protruding part of the rotating rod abuts against the sliding plate, causing the sliding plate to slide up and down, vibrating the coal blocks. This causes the coal dust on the surface of the coal blocks to fall off through the holes. Under the action of the air pump, the coal dust accumulates on the filter plate and the discharge plate. When the air pump is turned off, most of the coal dust falls onto the discharge plate. When the filter plate is pulled out, the scraper removes the residual coal dust on the filter plate, improving the dust removal effect and ensuring that the air circulation rate is not affected.

The limiting rod 608 abuts against the discharge plate 607, and the discharge plate 607 closes to prevent coal dust from flowing back and affecting work efficiency when the air pump 10 is operating.

[0025] A filter mechanism 7 is provided on the mounting frame 1. The filter mechanism 7 includes a rotating rod 701, which is rotatably connected to the coal storage bin 2. The left side of the rotating rod 701 passes through the coal storage bin 2 and is fixed to the output shaft of the motor 5. The motor 5 is fixed to the coal storage bin 2. A sliding plate 702 is provided above the rotating rod 701 and is slidably connected to the coal storage bin 2. A vent is provided at the right end of the coal storage bin 2. When the rotating rod 701 of the motor 5 is started, it abuts against the sliding plate 702, causing the sliding plate 702 to slide up and down and vibrate the coal block. When the coal block vibrates, the coal dust on the surface falls below through the holes on the sliding plate 702. A scraper 703 is fixedly installed at the right end of the coal storage bin 2. A filter plate 704 is provided on the right side of the scraper 703 and is slidably connected to the filter box 9. A handle 705 is fixedly installed on the filter plate 704.

[0026] A sealing cover 3 is fixedly installed on the top of the coal storage bin 2, and a feed pipe 4 is fixedly installed on the top of the sealing cover 3. A filter box 9 is fixedly installed on the right side of the coal storage bin 2, and an air pump 10 is fixedly installed on the right side of the filter box 9. There are two sets of discharge ports 606. The discharge port 606 is opened on the mounting frame 1. The discharge port 606 on the mounting frame 1 is located directly below the discharge port 606 on the coal storage bin 2. A collection box 8 is set at the bottom of the mounting frame 1.

The two sets of discharge plates 607 are placed horizontally, and the ends of the two sets of discharge plates 607 away from the center are hinged to the coal storage bin 2.

[0027] The bottom of the connecting rod 610 away from the connecting plate 609 abuts against the filter plate 704. The side of the filter plate 704 away from the handle 705 is inclined. The side of the filter plate 704 near the coal storage bin 2 is concave in the middle. The end of the extension rod 604 away from the limiting block 603 abuts against the concave part of the filter plate 704. The scraper 703 abuts against the concave part of the filter plate 704. The rotating rod 701 is convex. Holes are opened on the sliding plate 702. Ventilation holes are opened on the right side of the coal storage bin 2. Ventilation holes are opened on both sides of the filter box 9. All ventilation holes are aligned. The left side of the air pump 10 is aligned with the ventilation holes. The bottom of the air pump 10 is fixed to the top of the mounting frame 1.

[0028] Working principle: When this utility model is in operation, coal blocks are first fed into the coal storage bin 2 through the feed pipe 4. The motor 5 is started to drive the rotating rod 701 to rotate. The protruding part of the rotating rod 701 abuts against the sliding plate 702, causing the sliding plate 702 to slide up and down and vibrate the coal blocks. The coal dust on the surface of the coal blocks is vibrated down and falls from the holes onto the inclined plate 601 and the discharge plate 607. The air pump 10 is started and the coal dust gathers to the right. The air pump 10 is turned off and the filter plate 704 is pulled out, releasing the limit on the extension rod 604. The spring 605 rebounds and drives the limit rod 608 and the limit block 603 to reset. The limit block 603 releases the limit on the inclined plate 601. The spring 602 rebounds and abuts against the inclined plate 601 to reset it. The inclined plate 601... When the left end moves upward, the spring force of the reset will cause the coal dust attached to the surface of the inclined plate 601 to fall into the discharge port 606 through the inclined surface. When the filter plate 704 releases the limit on the connecting rod 610, the connecting rod 610 drives the connecting plate 609 to descend. The limit rod 608 descends to release the limit on the discharge plate 607. The discharge plate 607 resets and rotates downward to open, and the coal dust falls into the collection box 8. When the filter plate 704 is pulled, the scraper 703 abuts against the filter plate 704 to scrape off the coal dust attached to the filter plate 704. The coal dust falls into the collection box 8. Then the filter plate 704 is pushed in, and the air pump 10 is turned on to continue working. The operation is repeated. When all the coal pieces are cleaned, the motor 5 is turned off, and the collection box 8 is taken out to clean the coal dust.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
