Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, and particularly relates to a sealing structure of a bag dust collector. Background Technique

[0002] A bag dust collector is a dry dust filtering device, which is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the fiber fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained and the gas is purified.

[0003] However, there are still deficiencies in the use of related bag dust collectors. Firstly, the sealing performance at the connection between the bag and the partition is poor, resulting in the direct discharge of dust-laden gas without passing through the bag for filtration. Moreover, the ash outlet of the ash hopper is not convenient for effective sealing, prone to air leakage, reducing the dust removal efficiency. Therefore, we propose a sealing structure of a bag dust collector to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sealing structure of a bag dust collector, which can effectively seal the connection between the bag and the partition, prevent the direct discharge of dust-laden gas without passing through the bag for filtration, improve the dust removal effect, and is conducive to effectively sealing the ash hopper outlet to avoid air leakage, greatly improving the dust removal effect and efficiency. At the same time, when discharging ash, the gate plate can be rotated to the vertical state without blocking the ash hopper outlet.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: It includes a machine body and three filter bags. The top of the machine body is rotatably connected with a top cover, and a fixed sealing component is arranged between the top cover and the machine body. A partition is fixedly connected inside the machine body. Three mounting holes are opened at the top of the partition. A sealing connection component is arranged among the mounting holes, the partition and the filter bags. The bottom of the machine body is fixedly communicated with an ash hopper outlet, a sealing mechanism is arranged on the ash hopper outlet, an air inlet is fixedly communicated with the bottom of one side of the machine body, and an air outlet is fixedly communicated with the top of the other side of the machine body.

[0006] The further setting of the utility model is: The sealing mechanism includes a rotating shaft rotatably connected to the inner walls of the front and rear sides of the ash hopper outlet and two limiting plates fixedly connected to the front side of the ash hopper outlet. A gate plate is fixedly sleeved on the outer side of the rotating shaft. A sealing block is fixedly connected to one side of the gate plate. The sealing block is movably abutted against the inner wall of one side of the ash hopper outlet. A rotating plate is fixedly connected to the front end of the rotating shaft. A threaded groove is opened on the front side of the rotating plate.

[0007] By adopting the above technical solution, when the dust is not discharged, the rotating plate abuts against the limiting plate in the upper left corner, and the screw on the baffle is screwed into the threaded groove opened on the rotating plate to lock the rotating plate. At this time, the rotating shaft and the gate plate are in a horizontal state. Through the arrangement of the gate plate and the sealing block, the dust hopper outlet can be blocked and sealed, avoiding air leakage at the dust hopper outlet and reducing the dust removal effect and efficiency. When it is necessary to discharge the dust, loosen the screw so that the screw disengages from the threaded groove and does not fix the rotating plate. At this time, rotate the rotating plate downward to the right through the handle. The rotating plate drives the rotation of the rotating shaft, and the rotating shaft drives the downward rotation of the gate plate and the sealing block to the vertical state. At this time, the rotating plate is located inside the lower limiting plate and the baffle. Then tighten the lower screw so that the lower screw is screwed into the threaded groove to fix the rotating plate, and thus the dust hopper outlet is not blocked. At this time, the dust in the dust hopper is discharged from the dust hopper outlet. After the discharge is completed, reverse the above steps to make the rotating plate rotate to the vertical state and lock it with the upper screw. At this time, the gate plate rotates to the horizontal state to block the dust hopper outlet.

[0008] A further setting of the present utility model is that baffles are fixedly connected to one side of the left limiting plate and the top of the lower limiting plate, and screws are threadedly connected to the front sides of the two baffles, and the upper screw is threadedly connected in the threaded groove.

[0009] By adopting the above technical solution, it is beneficial to lock the rotating plate and avoid the shaking of the gate plate from affecting the sealing effect of the dust hopper outlet.

[0010] A further setting of the present utility model is that a handle is fixedly connected to the top of the rotating plate.

[0011] By adopting the above technical solution, it is convenient to pull the rotating plate.

[0012] A further setting of the present utility model is that the sealing connection assembly includes a sealing ring fixedly sleeved on the outer side of the cloth bag, a connecting ring is fixedly connected to the top of the sealing ring, the connecting ring is movably placed on the top of the partition plate, two sealing rings are fixedly connected to the outer side of the sealing ring, the sealing ring is slidably sleeved in the mounting hole, two sealing grooves are opened on the inner wall of the mounting hole, and both sealing rings are slidably sleeved in the corresponding sealing grooves. Two lower screw rods are threadedly connected to the top of the connecting ring, and the connecting ring is fixedly connected to the top of the partition plate through the two lower screw rods.

[0013] By adopting the above technical solution, through the settings of the connecting ring, lower screw rod, mounting hole and sealing ring, it is beneficial to connect and fix the cloth bag on the partition board, and at the same time, it is beneficial to disassemble the cloth bag for regular cleaning and replacement. Through the settings of the sealing ring, sealing gasket and sealing groove, the effect of multiple seals can be achieved, so that no air leakage occurs at the connection between the cloth bag and the partition board, and it is avoided that the dust-laden gas is directly discharged without passing through the cloth bag filtration, thus reducing the dust removal effect.

[0014] The further setting of the present utility model is: the fixed sealing assembly includes a sealing gasket fixedly connected to the bottom of the top cover, two lower ear plates fixedly connected to one side of the machine body, and two upper ear plates fixedly connected to one side of the top cover. The same upper screw rod is threadedly connected between the adjacent lower ear plate and upper ear plate, and the sealing gasket is movably abutted against the top of the machine body.

[0015] By adopting the above technical solution, through the settings of the upper ear plate, lower ear plate and upper screw rod, the top cover can be fixed and disassembled. Through the sealing gasket, the connection between the top cover and the machine body can be sealed, improving the overall sealing performance of the machine body and avoiding air leakage.

[0016] The beneficial effects of the present utility model are:

[0017] 1. When the present utility model does not discharge dust, the rotating plate is abutted against the upper left limiting plate, and the screw on the baffle is screwed into the threaded groove opened on the rotating plate to lock the rotating plate. At this time, the rotating shaft and the gate plate are in a horizontal state. Through the settings of the gate plate and the sealing block, the ash hopper outlet can be blocked and sealed, avoiding air leakage at the ash hopper outlet and reducing the dust removal effect and efficiency. When it is necessary to discharge dust, loosen the screw so that the screw disengages from the threaded groove and does not fix the rotating plate. At this time, rotate the rotating plate downward to the lower right, and the rotating plate drives the rotation of the rotating shaft. The rotating shaft drives the downward rotation of the gate plate and the sealing block to the vertical state. At this time, the rotating plate is located inside the lower limiting plate and the baffle below. Then tighten the lower screw so that the lower screw is screwed into the threaded groove to fix the rotating plate, and then the ash hopper outlet is not blocked. At this time, the dust in the ash hopper is discharged from the ash hopper outlet. After discharging, reverse the above steps, rotate the rotating plate to the vertical state, and lock it with the upper screw. At this time, the gate plate rotates to the horizontal state to block the ash hopper outlet.
