Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, in particular to an anti-clogging dust removal filter bag. Background Art

[0002] The filter bag is a key part in the operation of the bag dust collector. Usually, the cylindrical filter bag is hung vertically in the dust collector. The fabric and design of the filter bag should strive for high-efficiency filtration, easy dust removal and durability. The filter bag has excellent chemical stability and heat resistance. It is the highest performance representative in the filter material industry and the highest-end performance variety among all commonly used filter materials. It has reached a high level in terms of filtration efficiency and filtration accuracy.

[0003] After searching, the Chinese patent with publication number CN219836247U discloses an anti-clogging dust filter bag, including a filter bag body, an upper connecting plate and a lower connecting plate, the upper connecting plate and the lower connecting plate are respectively connected to a first connecting tube and a second connecting tube at opposite ends, and the filter bag body is connected between the first connecting tube and the second connecting tube by a clamp; both sides of the bottom of the lower connecting plate are fixedly connected with telescopic rods, and a connecting plate is fixedly connected between the other ends of the two telescopic rods, and springs are sleeved on the outer sides of the two telescopic rods. The utility model solves the problem that the sticky stick loses its stickiness after being contaminated with dust, and thus has no effect of cleaning the dust in the filter bag, or has a poor cleaning effect, by setting the filter bag body, the upper connecting plate, the lower connecting plate, the first connecting tube, the second connecting tube, the telescopic rod, the connecting plate, the spring and the vibration motor. It not only reduces the strength of personnel, but also avoids the filter bag being unable to be used when the sticky stick is replaced, affecting the efficiency of dust removal.

[0004] In the above-mentioned prior art solution, the vibration motor drives the lower connecting plate to move up and down reciprocatingly, so that the filter bag body can be reciprocated between a contracted and a tightened state. When the filter bag body changes from a contracted state to a tightened state, the filter bag body will vibrate, so that the dust adsorbed on the surface of the filter bag body can be automatically cleaned. However, in actual use, since the air contains a certain amount of moisture, the contact between the moisture and the dust and the filter bag body will firmly adhere the dust to the side wall of the filter bag body. After the moisture in the dust evaporates, the dust will agglomerate on the side wall of the filter bag body. It is difficult to shake off the agglomerated dust by vibration, resulting in poor dust removal effect. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes an anti-clogging dust removal filter bag. Through the rotation of the motor output shaft, the scraper will scrape off the dust attached to the inner wall of the filter bag body, then gather it along the side wall of the scraper, and finally fall off from the side wall of the scraper.

[0006] The technical solution to achieve the purpose of the utility model is: an anti-clogging dust filter bag, including a filter bag body, the top wall of the filter bag body is clamped with an upper connecting plate, the bottom wall of the filter bag body is clamped with a lower connecting plate, the top wall of the upper connecting plate is fixedly mounted with a motor, the output shaft of the motor is fixedly mounted with a rotating shaft, a plurality of connecting rods are fixedly mounted on the side wall of the rotating shaft at equal intervals, a scraper is fixedly mounted on the end of the connecting rod away from the rotating shaft, the scraper is fitted with the inner wall of the filter bag body, and the scraper is in an "X" shape.

[0007] In some embodiments, a plurality of connecting blocks are fixedly installed on the bottom wall of the lower connecting plate, a positioning plate is fixedly installed on the bottom wall of the connecting block, a plurality of guide blocks are fixedly installed at equal intervals on the top wall of the positioning plate, an extrusion block is slidably installed on the inner side wall of the lower connecting plate, and a plurality of positioning rods are fixedly installed at equal intervals on the side wall of the extrusion block.

[0008] In some embodiments, the side wall of the guide block is arranged to be inclined, and the side wall of the positioning rod and the side wall of the guide block are in contact with each other.

[0009] In some embodiments, the inner wall of the lower connecting plate is aligned with the inner wall of the filter bag body, the top wall of the extrusion block is in contact with the side wall of the scraper near the bottom, and the bottom end of the rotating shaft extends outward through the interior of the extrusion block.

[0010] In some embodiments, a limiting groove is provided on the inner side wall of the extrusion block, a limiting block is slidably installed inside the limiting groove, and the limiting block is fixedly installed on the side wall of the rotating shaft.

[0011] In some embodiments, a reinforcement rod is fixedly mounted on the top of the side wall of the positioning rod, and the top end of the reinforcement rod is fixedly mounted on the side wall of the extrusion block.

[0012] Compared with the prior art, the utility model has the following significant advantages:

[0013] First, the utility model, through the rotation of the motor output shaft, makes the scraper rotate inside the filter bag body along with the rotating shaft through the connecting rod, and the scraper is in contact with the inner wall of the filter bag body, so the scraper will scrape off the dust attached to the inner wall of the filter bag body, and the scraper is in an "X" shape, so after the scraper scrapes off the dust on the inner wall of the filter bag body, it gathers along the side wall of the scraper, so that the dust can easily fall off from the side wall of the scraper, so that the scraper can scrape off more dust; it solves the problem of existing dust agglomeration, which makes it difficult to remove.

[0014] Second: In the utility model, as the rotating shaft rotates with the output shaft of the motor, under the guidance of the guide block, the extrusion block will move upward, and squeeze the scraper on the top of the extrusion block. The scraper will be deformed after being squeezed. As the extrusion block continues to rotate, the positioning rod will move to the lowest end of the upper side wall of the guide block. The elasticity of the scraper will push the extrusion block to move downward, and the scraper will therefore return to its original state. During the repeated deformation of the scraper, the dust accumulated on the side wall of the scraper will easily fall off, thereby avoiding the accumulation of dust on the side wall of the scraper.
