Description

Technical Field

[0001] The utility model relates to the field of dust collectors, and more specifically, to a bag dust collector. Background Art

[0002] The bag dust collector filters the solid particles entrained in the gas through a cloth bag with meshes, and then makes the solid particles attached to the surface of the cloth bag fall off through regular reverse airflow, and then discharges the solid particles and the airflow from two outlets. It is a common dust removal device. Usually, the solid particles leave the bag dust collector through a hopper located at the bottom of the bag dust collector. However, the falling solid particles sometimes adhere to the inner side wall of the hopper, resulting in blockage in the hopper, and the bottom end of the hopper is relatively narrow, making it inconvenient to clean.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a bag dust collector.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A bag dust collector includes a hopper. On both inner side walls of the hopper, there are slidingly connected mesh plates. The mesh plates slide along the direction from the top end of the side wall of the hopper to the bottom end of the side wall of the hopper. The bottom of the mesh plate is fixedly connected with a pull rod. The bottom end of the pull rod is located below the hopper, and the mesh piece fits the inner side wall of the hopper.

[0006] The utility model is further provided that: A number of reinforcing ribs are fixedly connected to the mesh plate, and the length direction of the reinforcing ribs is the same as the sliding direction of the mesh plate.

[0007] The utility model is further provided that: The bottom end of the reinforcing rib is connected to the pull rod.

[0008] The utility model is further provided that: The reinforcing rib includes an upper section and a lower section. The bottom end of the upper section is rotatably connected to the top end of the lower section. The mesh piece is divided into two pieces along the length direction of the upper section, and the upper section and the lower section are respectively fixedly connected to a mesh plate.

[0009] The utility model is further provided that: The bottom end of the upper section is rotatably connected with a rotating shaft. The rotating shaft is rotatably connected with the lower section, and both between the rotating shaft and the upper section and between the rotating shaft and the lower section are detachably connected.

[0010] The utility model is further provided that: The bottom end of the lower section is rotatably connected to the pull rod.

[0011] In summary, the utility model has the following beneficial effects: The mesh moves along with the pull rod, so that a relative movement is formed between the inner wall of the hopper and the mesh, driving the solid particles on the inner wall of the hopper to move outwards, cleaning the inner wall of the hopper, avoiding the blockage of the hopper, improving the efficiency of the dust collector. Each time only one side of the mesh is drawn out, avoiding the interference between the two meshes. The mesh extending out of the hopper is easy to clean, improving the efficiency of cleaning and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model will be described in detail below with reference to the drawings and embodiments.

[0016] Embodiment: A bag-type dust collector, as Figure 1 , Figure 2 shown, includes a hopper 1. Mesh plates 2 are slidably connected to both inner walls of the hopper 1. The mesh plates 2 slide along the direction from the top end of the side wall of the hopper 1 to the bottom end of the side wall of the hopper 1. The bottom of the mesh plate 2 is fixedly connected to a pull rod 3. The bottom end of the pull rod 3 is located below the hopper 1. The mesh fits against the inner wall of the hopper 1.

[0017] Specifically, the mesh is composed of a number of steel bars perpendicular to each other. When solid particles adhere to the inner wall of the hopper 1, the solid particles accumulate on the mesh and in the meshes of the mesh. When the pull rod 3 is pulled, the mesh moves along with the pull rod 3, so that a relative movement is formed between the inner wall of the hopper 1 and the mesh, driving the solid particles on the inner wall of the hopper 1 to move outwards, cleaning the inner wall of the hopper 1, avoiding the blockage of the hopper 1, improving the efficiency of the dust collector. Each time only one side of the mesh is drawn out, avoiding the interference between the two meshes. The mesh extending out of the hopper 1 is easy to clean, improving the efficiency of cleaning and maintenance.

[0018] As Figure 1 , Figure 2As shown, a number of reinforcing ribs are fixedly connected to the wire mesh plate 2. The length direction of the reinforcing ribs is the same as the sliding direction of the wire mesh plate 2. The bottom end of the reinforcing rib is connected to the pull rod 3. The reinforcing rib includes an upper section 4 and a lower section 5. The bottom end of the upper section 4 is rotatably connected to the top end of the lower section 5. The wire mesh is divided into two pieces along the length direction of the upper section 4. The upper section 4 and the lower section 5 are respectively fixedly connected to one piece of the wire mesh plate 2. A rotating shaft 6 is rotatably connected to the bottom end of the upper section 4. The rotating shaft 6 is rotatably connected to the lower section 5. The connection between the rotating shaft 6 and the upper section 4 and the connection between the rotating shaft 6 and the lower section 5 are both detachable. The bottom end of the lower section 5 is rotatably connected to the pull rod 3.

[0019] Specifically, the two upper sections 4 are integrally formed with one piece of wire mesh, and the two lower sections 5 are integrally formed with the other piece of wire mesh. The upper section 4 and the lower section 5 are rotatably connected through the rotating shaft 6. The middle of the rotating shaft 6 is a smooth rod, and threaded sections are formed at both ends of the rotating shaft 6. The rotating shaft 6 passes through the upper section 4 and the lower section 5 at the same time, and nuts are threadedly connected to both ends of the rotating shaft 6. Sliding grooves matching with the upper section 4 and the lower section 5 are provided on the inner side wall of the hopper 1. The upper section 4 and the lower section 5 improve the strength of the wire mesh. At the same time, because the pull rod 3 is connected to the lower section 5, the lower section 5 and the upper section 4 are subjected to tensile force, ensuring the service life of the wire mesh. The relative rotation between the upper section 4 and the lower section 5 enables the lower section 5 to rotate when it is outside the hopper 1, reducing the possibility of interference between the lower section 5 and the outside during the process of continuously sliding the upper section 4 outwards. Connection pieces are integrally formed at both ends of the pull rod 3, and the two connection pieces are respectively rotatably connected to one section of the lower section 5, keeping the width direction of the pull rod 3 vertically downward under normal conditions to reduce the solid particles accumulated on the pull rod 3.

[0020] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
