Description

Technical Field

[0001] The utility model relates to the technical field of dust removal fan cleaning, in particular to a dust removal fan facilitating the cleaning of a filter screen. Background Technique

[0002] A dust removal fan is a device used to control and reduce dust pollution in industrial production processes. Its working principle mainly relies on mechanical forces, such as centrifugal force, to separate particles in the dust-containing gas, achieving air purification. The fan generates centrifugal force through the high-speed rotation of the impeller, causing the dust particles to be thrown towards the housing and separated due to inertia. The purified gas is discharged from the fan outlet, while the dust falls into the ash hopper and is discharged through the dust outlet or further processed. A dust removal fan generally includes an impeller, a housing, an air inlet, a motor, and a transmission part. The impeller is the core component, consisting of multiple blades, responsible for generating centrifugal force, and the housing is used to guide the air flow and collect dust.

[0003] In practical applications, a dust removal fan is usually equipped with a filter screen to capture and filter dust particles, ensuring that the discharged air quality meets environmental protection standards. However, the fixing structure of the filter screen (such as bolts and clamping blocks) needs to be loosened or tightened one by one, which is time-consuming and labor-intensive. In a production environment where the filter screen needs to be frequently cleaned or replaced, this cumbersome disassembly and installation process will take up a large amount of manual time and may require multiple people to cooperate to complete. In addition, the use of tools (such as wrenches, screwdrivers) during the operation increases the risk, and improper operation may cause the tool to slip or injure the operator. Frequent disassembly and installation may also accelerate the wear of the fixing parts, increasing the maintenance and replacement costs. On a production line that requires quick response, this delay may affect the efficiency of the entire production process. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a dust removal fan facilitating the cleaning of a filter screen, which can effectively solve the problems raised in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A dust removal fan facilitating the cleaning of a filter screen, including a fan base, a driving device, a transmission device, and a fan main body. The driving device and the fan main body are both installed on the fan base. The driving device is connected to the air wheel in the fan main body through the transmission device and drives the air wheel to rotate, thereby realizing the operation of the dust removal fan.

[0007] The side wall of the main body of the fan is provided with a wind cylinder, and an air outlet is opened at the port of the wind cylinder. An inner fixing frame is provided at the opening of the air outlet, and a connecting frame is provided on the side wall of the inner fixing frame. A movable block is connected to the connecting frame, and an elastic hoop is connected through the movable block. Docking holes are formed at the edge of the elastic hoop, and mounting holes adapted to the docking holes are formed on the inner fixing frame. Bolts are inserted into the mounting holes and the docking holes to realize the connection between the elastic hoop and the inner fixing frame;

[0008] An outer frame is embedded in the clamping cavity formed between the inner fixing frame and the elastic hoop, and a filter mesh cover for filtering is installed inside the frame of the outer frame. The outer frame and the filter mesh cover can be taken out for cleaning by opening the elastic hoop, which is convenient for later maintenance and cleaning.

[0009] In a further preferred solution, detours are provided at two quadrant points of the elastic hoop, and the detours are integrally designed with the elastic hoop. The cross-section of the detour is designed in a "C" shape, and the protruding direction of the detour is towards the center of the elastic hoop, and the connection between the detour and the elastic hoop is designed in an arc shape;

[0010] In a further preferred solution, the elastic hoop is made of an elastic metal plate, and when the elastic hoop deforms, it bends towards the center of the elastic hoop and also towards the opening direction of the air outlet;

[0011] In a further preferred solution, the elastic hoop is welded and fixed to the movable block, and a rotating shaft is installed on the movable block and connected to the connecting frame through the rotating shaft. The movable block rotates in the connecting frame through the rotating shaft;

[0012] In a further preferred solution, the inner fixing frame is integrally designed with the connecting frame, and the inner fixing frame is fixed on the wind cylinder by bolts. An arc-shaped movable groove adapted to the movable block is formed on the connecting frame, which is convenient for the large-angle movement of the movable block;

[0013] In a further preferred solution, the outer frame is welded and fixed to the filter mesh cover, and both the outer frame and the filter mesh cover are made of elastic metal materials. A notch adapted to the movable block is formed on the side wall of the outer frame, which is convenient for the outer frame to be clamped in the clamping cavity between the inner fixing frame and the elastic hoop.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In this utility model, through the structural design of the quick-detachable filter screen cover, users can quickly remove the outer frame and the filter screen cover for cleaning, saving the time for cleaning and maintenance. Since the filter screen cover is easy to disassemble, users can more conveniently conduct regular inspections and maintenance, ensuring the normal operation of the fan and extending the service life of the equipment. Users can disassemble and clean after turning off the power and unplugging the power plug, reducing the potential safety hazards during the operation process. The easy-disassembly design makes the cleaning process more user-friendly, reduces the operation difficulty for users, and improves user satisfaction.

[0016] The quick-detachable structure makes the cleaning work more frequent and efficient, helps reduce the dust accumulation inside the fan, and improves the dust removal effect of the fan. Since it is made of elastic metal materials, the filter screen cover and related components are not easily damaged during frequent disassembly and cleaning, improving the overall durability.

[0017] The design of the elastic hoop and the movable block makes the disassembly and installation of the filter screen cover more flexible, adapting to the operating habits of different users. The detour part design on the elastic hoop further enhances the structural stability and durability, and also makes the disassembly and installation process smoother. Description of the Drawings
