Description

Technical Field

[0001] This utility model relates to the field of industrial production technology, specifically to a bag dust collection unloading device. Background Technology

[0002] In pneumatic conveying systems in industrial production, bag dust collectors are key dust collection and treatment devices. Their unloading process directly affects the operating efficiency and stability of the entire system. Rotary rotary valves, with their unique structural design and functional characteristics, are widely used in unloading ports under negative pressure conditions. They can not only achieve continuous material conveying through rotating impellers, but also effectively seal the discharge port to prevent backflow of air and ensure the smoothness of pneumatic conveying. This airlock function makes them an indispensable component in industrial unloading systems.

[0003] However, in practical applications, traditional rotary valves have obvious drawbacks during unloading operations. Since the material fills the gap between the impeller blades by its own weight, it is very easy to accumulate inside the hopper during the falling process. As the accumulation increases, the friction and extrusion pressure between the materials increase, eventually leading to hopper blockage. Once blockage occurs, it will not only interrupt the quantitative and continuous conveying of materials and affect the production progress, but may also cause a series of problems such as equipment overload and increased energy consumption, and may even require shutdown for cleaning, resulting in decreased production efficiency and increased maintenance costs. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a bag dust collector unloading device, comprising a star-shaped unloader and a hopper installed on the top of the star-shaped unloader, characterized in that: a plurality of radially extending tube sheets are evenly distributed circumferentially in the middle section of the impeller of the star-shaped unloader, and an anti-clogging mechanism is installed on the inner side of the hopper corresponding to the movement trajectory of the tube sheets;

[0005] The anti-clogging mechanism includes an outer cylinder fixedly connected to the inner wall of the hopper by two sets of symmetrically arranged support rods. An inner cylinder is fixed to the lower inner side of the outer cylinder, and a ring block is fixed at the top opening. A top rod passes through the inner cylinder and the ring block. The bottom end of the top rod is adapted to and abuts against the outer contour of the tube sheet, and a guide post is fixed on the outside. Two sets of guide holes are opened on the outside of the inner cylinder. The guide post is located in the guide hole. A cross rod is fixed to the top of the top rod, and an elastic reset component is also provided on the top rod.

[0006] Furthermore, the elastic reset assembly includes a sleeve block fixed to the outside of the top rod above the inner cylinder, and a spring is provided on the outside of the top rod between the sleeve block and the ring block.

[0007] Furthermore, the flower plate is petal-shaped, and the bottom end of the top rod that is in contact with the flower plate is a matching hemisphere.

[0008] Furthermore, the guide holes are inclined, with two guide holes symmetrically distributed along the outer side of the inner cylinder and inclined in opposite directions.

[0009] Furthermore, the support rod, outer cylinder, inner cylinder, and ring block are integrally formed.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] The unloading device of this baghouse dust collector utilizes the pushing action of the tube plate on the push rod when the rotary impeller of the star-shaped unloader rotates. This causes the push rod to drive the cross rod to periodically agitate and knock the material in the hopper, effectively preventing material accumulation and blockage. The elastic reset component allows the push rod to automatically reset without the need for an additional power source. The structure is simple and energy-efficient. The combination of the petal-shaped tube plate and the inclined guide hole allows the push rod to move not only up and down during operation but also to swing horizontally, enhancing the disturbance effect on the material, further improving the anti-blocking efficiency, increasing the overall reliability of the device, and reducing maintenance costs and downtime.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This embodiment of a bag dust collector unloading device includes a rotary valve 1 and a hopper 2 fixed to the top of the rotary valve 1. The hopper 2 is aligned with and fixedly connected to the feed inlet of the rotary valve 1. A perforated plate 3 is installed in the middle section of the impeller of the rotary valve 1. The perforated plate 3 is petal-shaped, and its radial extension direction is adapted to the outer diameter of the impeller. The outer cylinder 5 is fixed inside the hopper 2 by two sets of symmetrically arranged support rods 4. An inner cylinder 6 is fixed to the lower part of the inner side of the outer cylinder 5. A ring block 11 is fixed at the top opening of the outer cylinder 5. A top rod 9 is inserted and connected between the inner cylinder 6 and the ring block 11. The bottom end of the top rod 9... The end of the tube sheet 3 is a matching hemisphere. The bottom end of the push rod 9 is matched with the outer contour of the tube sheet 3 and keeps in contact. Two sets of guide posts 13 are fixed on the outside of the push rod 9. Two sets of guide holes 7 are opened on the outside of the inner cylinder 6. The guide holes 7 are inclined. The two guide holes 7 are symmetrically distributed along the outside of the inner cylinder 6 and the inclination directions are opposite. The guide posts 13 are located in the guide holes 7. The sleeve block 8 is fixed on the outside of the push rod 9 above the inner cylinder 6. A spring 10 is installed between the sleeve block 8 and the ring block 11 to form an elastic reset assembly. A cross rod 12 is fixed on the top of the push rod 9. The end of the cross rod 12 extends to the material area inside the hopper 2.

[0019] When the impeller of the star-shaped feeder starts to rotate, the petal-shaped plate rotates with the impeller. When the plate rotates, the protruding end can push the push rod. Due to the radial extension structure of the plate, it will push the push rod upward. When the push rod moves upward, the outer guide post moves in the inclined guide hole. Since the guide hole is inclined and symmetrically distributed with opposite inclination directions, the movement of the guide post will cause the push rod to swing horizontally while moving upward. When the push rod moves upward, it compresses the spring between the sleeve block and the ring block, and the cross rod at the top of the push rod moves upward and stirs the material in the hopper, preventing the material from accumulating at the top of the hopper. When the plate rotates away from the bottom of the push rod, the spring releases its elastic potential energy and pushes the push rod downward to reset. When the push rod moves downward, the guide post moves in the opposite direction in the inclined guide hole, causing the push rod to swing horizontally again. During the downward reset process, the cross rod moves downward and stirs the material in the hopper, further disrupting the material's accumulation structure and preventing blockage.

[0020] As the impeller of the rotary valve continues to rotate, the tube sheet periodically pushes the push rod up and down, while the cross rod forms a periodic stirring action in the hopper, effectively preventing material from accumulating and clogging in the hopper and ensuring smooth unloading.
