Description

Technical Field

[0001] This utility model relates to the field of coal powder filter technology, and in particular to a coal powder filter with coal accumulation recovery function. Background Technology

[0002] Coal powder filters are used to filter out large particles and other impurities from coal powder to ensure the purity of coal powder during transportation.

[0003] When a coal powder filter is used for a long time, coal powder will adhere to the inner wall of the filter. On the other hand, as large particles and debris that are filtered out accumulate, some coal powder will also adhere to them.

[0004] Existing coal powder filters require disassembly and cleaning after a period of use, which is time-consuming and labor-intensive and can affect production efficiency. Therefore, there is a need to provide a coal powder filter with coal accumulation recovery function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a coal powder filter with coal accumulation recovery function to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A pulverized coal filter with coal accumulation recovery function includes:

[0008] The filter comprises:

[0009] The pipe body is fixed to the external pipeline by flanges at both ends;

[0010] A fixing box is used to fix the tube in the middle section.

[0011] The filter plate is inserted into the fixing box and the inside of the tube;

[0028] Optionally, the circular spring and the support plate are movably connected inside the discharge pipe, with the outer side of the rubber ring fitting against the inner wall of the discharge pipe.

[0029] Optionally, the filter further includes:

[0030] The sealing plate is fixed to the top of the fixing box.

[0031] Optionally, it also includes an anti-clogging component, the anti-clogging component comprising:

[0032] The spring column is fixed at one end to the inside of the fixing box and at the other end to the side of the filter plate;

[0033] The retaining ring is fixed to the inner wall of the fixing box and the tube.

[0034] Optionally, the anti-blocking component further includes:

[0041] Compared with the prior art, the beneficial effects of this utility model are:

[0042] The recycling component activates a servo motor on the fixed plate during filter operation. This servo motor drives a rotating shaft, which in turn rotates a connecting rod on the connecting ring. The rotating rod then rotates a rubber hammer, which strikes one side of the tube. The servo motor then drives the rotating shaft in the opposite direction, simultaneously causing the rubber hammer on the connecting rod to rotate in the opposite direction until the rubber hammer strikes the other side of the tube. This reciprocating motion strikes the tube, dislodging coal dust from the inner wall. Fine coal dust is blown into the blast furnace along with the continuously fed coal dust. Larger particles with some coal dust attached and other debris fall to the lower end of the tube and are blown into the discharge pipe, landing on a pallet. As the amount of large particles and debris increases, the pallet and rubber ring move downwards, compressing the spring. This allows the sealing cover to be opened when not in production, emptying the discharge pipe and solving the problems of existing technologies. Attached Figure Description

[0064] Filter 1 is used to filter coal powder, pipe body 11 serves as support and is used to connect external pipes, and fixing box 12 facilitates the disassembly of filter plate 14, which is used to filter large particles and impurities in coal powder.

[0065] Recycling component 2, which includes:

[0066] Fixing plate 21 is fixed above both ends of tube body 11;

[0067] The servo motor 22 is fixed on the fixed plate 21, and its output end passes through and is rotatably connected to the fixed plate 21;

[0068] The rotating shaft 23 is rotatably connected to the output end of the servo motor 22;

[0069] Connecting rod 27 is fixed in the middle section of rotating shaft 23;

[0070] Rubber hammer 28 is fixed on connecting rod 27;

[0071] The discharge pipe 29 is fixed at the lower end of the pipe body 11;

[0072] The sealing cap 290 is screwed onto the lower end of the discharge pipe 29;

[0073] Recycling component 2 also includes:

[0074] Bearing 24 is fixed to the side of the fixing box 12;

[0075] Connecting ring 25 is sleeved on the middle section of rotating shaft 23;

[0076] The locking rod 26 passes through and is screwed to the side of the connecting ring 25, with one end close to the rotating shaft 23;

[0077] Recycling component 2 also includes:

[0078] The lower end of the round spring 291 is fixed to the inner bottom surface of the sealing cover 290;

[0079] The support plate 292 is fixed to the upper end of the coil spring 291;

[0080] Rubber ring 293 is fixed to the outer ring of the support plate 292.

[0081] The round spring 291 and the support plate 292 are movably connected inside the discharge pipe 29, and the outer side of the rubber ring 293 is attached to the inner wall of the discharge pipe 29.

[0082] The recycling component 2 facilitates the recycling of coal powder inside the tube 11, reducing waste. The fixing plate 21 provides support, the servo motor 22 provides a power source, the rotating shaft 23 transmits power, the bearing 24 supports the rotating shaft 23 and facilitates its rotation, the connecting ring 25 provides a connection, the locking rod 26 secures the connecting ring 25, the connecting rod 27 provides a connection, and the rubber hammer 28 is used to pound the tube 11.

[0083] Working principle:

[0084] While the filter 1 is in use, the servo motor 22 on the fixed plate 21 is started. The servo motor 22 drives the rotating shaft 23 to rotate, which in turn drives the connecting rod 27 on the connecting ring 25 to rotate. The rotation of the connecting rod 27 drives the rubber hammer 28 to rotate. The rubber hammer 28 strikes one side of the tube body 11. Then the servo motor 22 drives the rotating shaft 23 to rotate in the opposite direction, and at the same time drives the rubber hammer 28 on the connecting rod 27 to rotate in the opposite direction until the rubber hammer 28 strikes the other side of the tube body 11. This reciprocating motion strikes the tube body 11, knocking off the coal powder on the inner wall of the tube body 11. The fine coal powder is blown into the blast furnace along with the continuously input coal powder. Larger particles and debris with some coal powder attached fall to the lower end of the tube body 11 and are blown into the discharge pipe 29, landing on the support plate 292. As the large particles and debris gradually increase, the support plate 292 and the rubber ring 293 move down, and the round spring 291 is compressed. When not in production, the sealing cover 290 can be opened to empty the discharge pipe 29.

[0085] This step allows for the real-time recovery of coal dust within filter 1, preventing its accumulation.

[0086] Please see Figure 4-6 This embodiment, based on the above embodiments, further includes:

[0087] Anti-blocking component 3, which includes:

[0088] The spring post 34 is fixed at one end to the inside of the fixing box 12 and at the other end to the side of the filter plate 14.

[0089] The retaining ring 37 is fixed to the inner wall of the fixing box 12 and the tube body 11;

[0090] Anti-blocking component 3 also includes:

[0091] Support block 31 is fixed to the inner wall of the fixing box 12;

[0092] The card slot 32 is provided on the support block 31;

[0093] The card block 33 is inserted into the card slot 32 and its side is fixed to one end of the spring post 34;

[0094] Anti-blocking component 3 also includes:

[0095] Screw 35 is fixed to the other end of spring post 34 away from the locking block 33;

[0096] A countersunk hole 36 is formed at the upper end of the filter plate 14, and a screw 35 is inserted into the countersunk hole 36 and fixed by a nut;

[0097] The anti-clogging component 3 can prevent the filter plate 14 from clogging. The support block 31 provides support, the slot 32 and the block 33 provide connection and are used to connect the spring column 34, the screw 35 and the countersunk hole 36 are used to connect the filter plate 14, and the retaining ring 37 provides blocking.

[0098] Working principle:

[0099] Insert one end of the screw 35 of the spring column 34 into the countersunk hole 36 on the filter plate 14 and tighten it with a nut. Then, insert the locking block 33 on the other side of the spring column 34 into the locking groove 32 of the support block 31. When conveying coal powder, the high-pressure airflow drives the coal powder to move, pushing the filter plate 14 to adhere to the retaining ring 37. The movable end of the spring column 34 is stretched. When the coal powder is conveyed, the movable end of the spring column 34 retracts, causing the filter plate 14 to spring back to its original position, and some of the large particles and impurities attached to the filter plate 14 fall off.

[0100] This step can reduce the deposits on the filter plate 14 and extend the service life of the filter plate 14.
