Description

Technical Field

[0001] The utility model relates to the technical field of air filtration, in particular to a control box of a self-cleaning air filter. Background Art

[0002] With the rapid development of industrialization and urbanization, air quality issues have become increasingly prominent. As an important device for improving air quality, air filters have been widely used in various fields. Self-cleaning air filters are a relatively common and efficient air filter that is energy-saving and environmentally friendly, safe and reliable and can be automatically cleaned.

[0003] The self-cleaning air filters currently available on the market require the filter barrels to be taken out and replaced one by one when replacing the filter barrels, which increases the workload of employees. During replacement, if one or more filter barrels are missing, the filtering effect of the filter will be affected and the filtering work may even be unable to continue. In addition, the controllers on the existing filters are either single-function or expensive, and require professional technicians to operate and debug, which increases the difficulty for users to use self-cleaning air filters. Therefore, we propose a control box for a self-cleaning air filter to solve the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A control box of a self-cleaning air filter, comprising a filter box, a filter bin and an air outlet bin are arranged inside the filter box, an air inlet and an air outlet are arranged on both sides of the filter box for air intake and air outlet, respectively, wherein the air inlet is communicated with the filter bin, and the air outlet is communicated with the air outlet bin, a dust collecting box for collecting dust is arranged at the bottom of the filter box, an opening is opened on one side of the filter box, a sealing door is hinged on the filter box at the opening, a control panel is fixedly connected to one side of the filter box at the air outlet, and the control box further comprises:

[0007] A plurality of filter barrels, each of which is arranged inside the filter box, and each of which is fixed with a filter bag for filtering air;

[0008] An installation component is arranged inside the filter box to facilitate the installation of the filter barrel in the filter box;

[0009] A self-cleaning component is arranged on the filter box body and is used for automatically cleaning dust from the filter component.

[0010] In one possible design, the mounting assembly includes a baffle, which is fixedly connected to the inner wall of the filter box. The baffle is provided with a plurality of slots, and the inner walls of the plurality of slots are slidably connected with a mounting plate. The mounting plate is provided with a mounting hole corresponding to the filter barrel, and the filter barrel is inserted into the corresponding mounting hole and fixedly connected to the mounting hole.

[0011] In a possible design, the bottom of the mounting plate is rotatably connected to a sealing cover corresponding to the mounting hole, and two torsion springs are sleeved on the sealing cover, both ends of the torsion spring are fixedly connected to the sealing cover, and the protruding end of the torsion spring is fixedly connected to the mounting plate.

[0012] In one possible design, the self-cleaning component includes a compressed air source, which is fixedly arranged on one side of the filter box, and a plurality of back-blow pulse valves are fixedly connected to the compressed air source, and the air outlet ends of the plurality of back-blow pulse valves are fixedly connected to delivery pipes, and the plurality of delivery pipes pass through one side of the filter box and extend to the interior of the filter box, and a Venturi tube corresponding to the filter barrel is fixedly arranged on the plurality of delivery pipes, and the Venturi tube is located directly above the filter barrel.

[0013] In a possible design, a pressure valve for monitoring the air pressure in the compressed air source is fixedly connected to the compressed air source, and the pressure valve is electrically connected to the control panel.

[0014] In a possible design, a pressure sensor for monitoring the air pressure therein is fixedly installed on the inner wall of one side of the filter bin and the air outlet bin, a pressure differential sensor for monitoring the pressure differential is fixedly installed on the inner wall of the filter bin and the air outlet bin on one side located at the air inlet and the air outlet, a temperature sensor and a humidity sensor for monitoring the temperature and humidity are fixedly installed on the inner wall of the filter bin on one side located at the air inlet, and the detection ends of the temperature sensor and the humidity sensor are close to the air inlet, and the pressure sensor, pressure differential sensor, temperature sensor and humidity sensor are all electrically connected to the control panel.

For example, the control panel can be set so that when the pressure difference reaches 600 Pa, the system will take protective functions and force the use of more reasonable back-blowing system parameters. By strengthening the back-blowing function, the pressure difference of the air filter can be reduced. When the pressure difference is lower than 600 Pa, the control device will be adjusted to the normal back-blowing parameters, and a signal transmission interface is left on the control panel to transmit the self-cleaning air filter operation signal to the host computer for remote control.
