Description

Technical Field

[0001] This utility model relates to the technical field of a reverse dust removal device for filter bags, specifically a reverse dust removal device for filter bags. Background Technology

[0002] A reverse-flow dust collector for filter bags is a cleaning device that uses high-pressure airflow to blow the inner surface of the filter bag in the opposite direction. It typically consists of a pulse valve, a blowpipe, and an air tank. During operation, the pulse valve opens instantaneously, and compressed air is injected into the filter bag through the nozzle, triggering an airflow impact that causes the dust adhering to the surface of the filter bag to fall off, restoring the filter bag's permeability and improving dust removal efficiency. It is widely used in baghouse dust collector systems.

[0003] Current dust removal devices have fixed-length blowpipes, which limit the distance at which they can blow onto the filter bags. They can often only clean the upper and middle parts of the filter bags, leaving the dust at the bottom of the bags untouched.

[0004] Therefore, we have made improvements to this and proposed a reverse dust removal device for filter bags. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a dust removal device for filter bags, comprising a housing, a structural box at the bottom of the housing, a structural groove inside the structural box, a plurality of electrically operated telescopic rods arranged in the structural groove, the bottom ends of the plurality of electrically operated telescopic rods passing through the bottom end of the structural groove and extending to the outside of the structural box, a blowpipe at the bottom end of each of the plurality of electrically operated telescopic rods, a plurality of ventilation hoses at the bottom end of the structural box, all of the plurality of ventilation hoses communicating with the blowpipes, and an equipment box at the top of the housing, an equipment groove inside the equipment box, a pulse valve arranged in the equipment groove.

[0007] As a preferred embodiment of this utility model, the top ends of several ventilation hoses pass through the top end of the structural groove and extend into the equipment groove, and all of the ventilation hoses are connected to the pulse valve.

[0008] As a preferred embodiment of this utility model, a pair of mounting blocks are connected to both sides of the housing, and a fixing bolt is threaded to the top of each mounting block.

[0009] As a preferred embodiment of this utility model, a controller is provided on one side of the housing.

[0010] As a preferred embodiment of this utility model, each of the several blowpipes is provided with a blowpipe nozzle at its bottom end.

[0011] The beneficial effects of this utility model are:

[0012] This utility model, through the combined use of an electric telescopic rod, a blowpipe, a structural box, and a structural groove, allows for convenient adjustment of the blowpipe position, facilitating easy cleaning of the bottom of the filter bag. The ventilation hose allows for convenient delivery of pulsed airflow to the blowpipe. Attached Figure Description

[0019] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0020] Example: Figure 1-4As shown, this utility model is a dust removal device for filter bags, including a housing 1. A structural box 2 is provided at the bottom of the housing 1. A structural groove 3 is provided inside the structural box 2. A plurality of electric telescopic rods 4 are provided in the structural groove 3. The bottom ends of the plurality of electric telescopic rods 4 pass through the bottom end of the structural groove 3 and extend to the outside of the structural box 2. A blow pipe 5 is provided at the bottom end of each of the plurality of electric telescopic rods 4. A plurality of ventilation hoses 6 are provided at the bottom end of the structural box 2. The plurality of ventilation hoses 6 are all connected to the blow pipes 5. An equipment box 7 is provided at the top of the housing 1. An equipment groove 8 is provided inside the equipment box 7. A pulse valve 9 is provided in the equipment groove 8.

[0021] The top ends of several of the ventilation hoses 6 pass through the top end of the structural groove 3 and extend into the equipment groove 8, and all of the ventilation hoses 6 are connected to the pulse valve 9.

[0022] The housing 1 has a pair of mounting blocks 10 connected to both sides, and the top of the mounting block 10 is threaded with a fixing bolt 11. The mounting block 10 and the fixing bolt 11 facilitate the installation of the entire device.

[0023] A controller 12 is provided on one side of the housing 1, which is convenient for staff to use.

[0024] Each of the blow pipes 5 is provided with a blow nozzle 13 at its bottom end, which can conveniently spray pulsed airflow onto the filter bag.

[0025] Working principle: Before use, the operator needs to securely install the device on the dust removal equipment using the mounting block 10 and fixing bolts 11. After connecting the ventilation hose 6 and power line, the controller 12 controls the electric telescopic rod 4 to move, causing the blowpipe 5 to drive the blow nozzle 13 to be aimed at the inside of the filter bag. When the pulse valve 9 is opened, compressed air enters the blowpipe 5 through the ventilation hose 6 and sprays a strong pulse airflow into the filter bag through the blow nozzle 13, effectively stripping the dust attached to the inner wall of the filter bag and causing it to fall into the dust collector or ash hopper. After cleaning, the operation can be repeated as needed to ensure that the filter bag maintains good ventilation and filtration effect.

[0026] Those skilled in the art should understand that the above description of the embodiments of the present invention is only intended to illustrate the beneficial effects of the embodiments of the present invention, and is not intended to limit the embodiments of the present invention to any of the examples given.
