Description

Technical Field

[0001] The utility model relates to the technical field of ash bunker discharging anti-blocking, in particular to an anti-blocking device for ash bunker discharging. Background Technique

[0002] The background technique of the ash bunker discharging anti-blocking device mainly stems from the in-depth understanding and research of common problems in the ash bunker discharging process. As a device for storing and transporting powdery, granular and other materials, the ash bunker is widely used in industrial production. However, during the discharging process, due to the influence of various factors such as material properties, environmental humidity, and silo structure, the ash bunker often has a blocking problem.

[0003] After consulting the relevant patent document CN220431613U, there are still some problems with the existing anti-blocking device for ash bunker discharging. The current optimization solutions on the market mainly include: by setting an interception grid, large-sized foreign objects can be intercepted and will not enter the discharger, avoiding blockage. Even if the discharger is blocked, only need to close the sluice valve and open the movable door to easily take out the foreign objects, without the need to repair and disassemble the discharger, greatly reducing the foreign object jamming of the discharger. However, this method is usually used to intercept larger foreign objects, and the interception effect on foreign objects such as iron filings is not obvious. In view of the above problems, an anti-blocking device for ash bunker discharging that can effectively intercept and temporarily collect is proposed. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-blocking device for ash bunker discharging, including a tank and a mounting hole. One side of the tank is fixedly connected with a discharge pipe. One end of the discharge pipe is fixedly connected with an elimination box. The surface of the elimination box is fixedly connected with a fixed angle iron. The two ends of the fixed angle iron are rotatably connected with fastening bolts. The inner wall of the fixed angle iron is in contact connection with a strong magnet. The strong magnet is in contact connection with the surface of the elimination box. One side of the elimination box is fixedly connected with a sealing cover plate. The sealing cover plate is fixedly connected with the inner wall of the elimination box through a fastening bolt. An installation hole is opened on the inner wall of the elimination box. A guide rod penetrates through the surface of the elimination box. The guide rod is slidably connected with the inner wall of the elimination box. The top of the guide rod is fixedly connected with a support plate. One side of the support plate is fixedly connected with a vertical plate. The bottom of the guide rod is fixedly connected with a connecting rod. One end of the connecting rod is fixedly connected with the surface of the vertical plate.

[0006] As a further improvement of the above solution, a limiting hole is opened inside the guide rod. The limiting hole is opened in the lower region of the guide rod. The bottom of the elimination box is fixedly connected with a pumping pipe. One end of the pumping pipe is fixedly connected with a pumping pump.

[0007] As a further improvement of the above solution, a sealing rubber pad is fixedly connected to the surface of the vertical plate. The sealing rubber pads are symmetrically distributed with the vertical plate as the axis. One end of the sealing rubber pad close to the surface of the vertical plate is thicker, and the end far from the surface of the vertical plate is thinner.

[0008] As a further improvement of the above solution, a blocking mechanism is arranged inside the vertical plate. The blocking mechanism includes a sliding groove. The sliding groove is opened inside the vertical plate. A limiting rod is fixedly connected to the bottom wall of the sliding groove, and a blocking block is slidably connected to the surface of the limiting rod.

[0009] As a further improvement of the above solution, a limiting groove is opened inside the blocking block. The limiting rod is inserted into the limiting groove, and the length of the limiting rod is greater than the depth of the limiting groove. A sliding rod is fixedly connected to one side of the blocking block, and a return spring is sleeved on the surface of the sliding rod.

[0010] As a further improvement of the above solution, the sliding rod penetrates through the inside of the vertical plate, and the sliding rod is slidably connected to the inside of the vertical plate. One end of the return spring is fixedly connected to the sliding rod, and the other end is fixedly connected to the surface of the vertical plate.

[0011] As a further improvement of the above solution, the edge of the blocking block is provided with a smooth rounded corner, and the radius of the rounded corner does not exceed half of the thickness of the blocking block. The thickness of the blocking block is slightly smaller than the depth of the sliding groove.

[0012] As a further improvement of the above solution, the strong magnets are arranged on the top, front, back, and right side of the elimination box. There are no strong magnets on the left and bottom of the elimination box. The strong magnets are in contact connection at the center of the surface of the elimination box.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For this anti-blocking device for discharging materials from the ash silo, when the pumping pump pumps the piled materials out of the tank, at this time, the piled materials enter the inside of the elimination box after passing through the discharge pipe. Since strong magnets are arranged on the surface of the elimination box, sundries such as iron filings in the piled materials can be effectively adsorbed on the inner wall of the elimination box. Then the piled materials will continue to flow out through the pumping pipe, effectively realizing the filtration and removal of iron filings and sundries in the piled materials.

[0015] 2. For the anti-blocking device for discharging ash from the ash bin, when a certain amount of iron filings is collected inside the elimination box, at this time, pull out the pin in the limit hole to release the limit on the guide rod, and then press the support plate so that the vertical plate and the guide rod slide downward inside the upper wall of the elimination box. Since the inner wall of the elimination box always abuts against the blocking block during the sliding process, the blocking block is always located inside the chute. Then, when the blocking block descends to the outlet of the discharge pipe, at this time, without the blockage on the inner wall of the elimination box, under the action of the return spring, the blocking block pops out along the limit rod to block the outlet of the discharge pipe. Due to the rounded corners on the edge of the blocking block, when the vertical plate rises, it can avoid using external force to return the blocking block, and only need the inner wall of the elimination box to abut against the edge of the blocking block to complete the reset. The setting of the sealing rubber pad enables the opening on the surface of the elimination box to be effectively sealed. Then loosen the fastening bolt inside the installation hole and remove the sealing cover plate, and the iron filings collected inside the elimination box can be cleaned up. The operation is simple, without the need to disassemble the elimination box for cleaning additionally, saving the maintenance cost and reducing the damage to the pumping pump.

[0026] Sealing rubber pads 101 are fixedly connected to the surface of the vertical plate 10. The sealing rubber pads 101 are symmetrically distributed with the vertical plate 10 as the axis. One end of the sealing rubber pad 101 close to the surface of the vertical plate 10 has a larger thickness, and the end far from the surface of the vertical plate 10 has a smaller thickness.

[0027] A blocking mechanism 13 is arranged inside the vertical plate 10. The blocking mechanism 13 includes a sliding groove 131. The sliding groove 131 is opened inside the vertical plate 10. A limiting rod 132 is fixedly connected to the bottom wall of the sliding groove 131. A blocking block 133 is slidably connected to the surface of the limiting rod 132.

[0028] A limiting groove 134 is opened inside the blocking block 133.

Due to the rounded corners provided at the edge of the blocking block 133, when the vertical plate 10 rises, it can avoid using external force to make the blocking block 133 return to its position. Only when the inner wall of the elimination box 3 abuts against the edge of the blocking block 133 can the reset be completed, and the setting of the sealing rubber pad 101 enables the opening on the surface of the elimination box 3 to be effectively sealed. Then loosen the fastening bolt 5 inside the mounting hole 8 to remove the sealing cover plate 7, and the iron filings inside the elimination box 3 can be cleaned.
