Abstract
Description
Technical Field
[0001] This utility model relates to the field of air filter technology, specifically to a filter sealing and cleaning device. Background Technology
[0002] Air filters are devices that remove suspended particulate matter and gaseous pollutants from the air through physical or chemical means, used to ensure air quality or protect mechanical equipment;
[0003] For example, the Chinese authorized patent with publication number CN219647012U (a plate and frame air filter) includes a first galvanized iron mesh and a second galvanized iron mesh. A fixed frame is fixedly connected to the outer wall of the first galvanized iron mesh, and several fixed frames are provided. Limiting blocks are movably connected to the inner walls of these fixed frames via connectors. In this plate and frame air filter, pressing down on the knob causes the knob to press down on the guide rod. The guide rod, along with the pressure plate on the outer wall, compresses the return spring, causing displacement and pushing the limiting block at the end of the guide rod out of the limiting groove. Rotating the knob then causes the knob to rotate, gradually bringing the limiting block at the end into contact with the cross-section of the through hole. Releasing the knob causes the return spring to spring back, moving the pressure plate and guide rod upwards. The guide rod then moves the limiting block upwards from the through hole until the limiting block and guide rod are completely disengaged from the second galvanized iron mesh.
[0004] However, in the current manufacturing process of chemical filters, the cutting, folding, and assembly of filter media generate a large amount of dust, debris, and carbon residue. The cleaning methods commonly used in the industry are brush cleaning and electrostatic adsorption, which cannot effectively remove contaminants from the surface of chemical filters, and the styles are limited and cannot be adapted to multiple filter sizes. Therefore, these methods do not meet the current needs. To address this, we have proposed a closed-loop filter cleaning device. Utility Model Content
[0005] The purpose of this utility model is to provide a filter sealing cleaning device to solve the problems mentioned in the background art. In the manufacturing process of chemical filters, a large amount of dust, debris and carbon ash residue are generated during the cutting, folding and assembly of filter media. Currently, the industry generally uses brush cleaning and electrostatic adsorption, which cannot effectively remove contaminants from the surface of chemical filters. In addition, the styles are limited and cannot be adapted to multiple filter sizes.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter sealing and cleaning device, comprising: a chemical filter, a filter placement platform at the lower end of the chemical filter, a top cover above the filter placement platform, a fan inside the top cover, an opening plate at the lower end of the fan, a frame outside the filter placement platform, and a lifting cylinder on one side of the frame, the lifting cylinder driving the top cover to move up and down.
[0007] Preferably, a connecting piece is provided at each corner of the top of the frame, and a safety light curtain is provided at the upper end of the connecting piece.
[0008] Preferably, the lower end of the filter placement platform is provided with a conical integrated hopper, and the lower end of the conical integrated hopper is provided with a detachable pollutant collector.
[0009] Preferably, the upper end of the filter placement platform is provided with a limiting bracket, and the limiting bracket is located on one side of the chemical filter.
[0010] Preferably, the moving end of the lifting cylinder is provided with a connecting lug, and the connecting lug is fixed to the top cover by screws, and the moving end of the lifting cylinder is fixed to the connecting lug by external bolts.
[0011] Preferably, a dual start button is provided on one side of the top of the frame, and a stop button is provided on one side of the dual start button.
[0012] Preferably, each corner at the bottom of the frame is provided with a caster wheel, and multiple caster wheels are provided.
[0013] Preferably, the top opening of the top cover is provided with an upper opening that extends through the top cover, and the frame is provided with a protective side plate on the outside.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] (1) This utility model uses the output end of the lifting cylinder to drive the top cover to move downward, close the top cover and the lifting cylinder. During the closing process, the safety light curtain must be free of interfering objects within the sensing range. After closing, the fan will automatically turn on and continue to blow according to the set time. The pollutants are collected in the conical integrated bucket to the detachable pollutant collector, so that the pollutants can be centrally recycled and treated. After the fan stops, press the double start button to start the lifting cylinder. The output end of the lifting cylinder drives the top cover to move upward, so that the chemical filter can be taken out, which improves production efficiency. Due to the use of fully enclosed automated cleaning equipment, the chemical filter cleaning process is more convenient, which shortens the production cycle and improves the overall production efficiency. It solves the problem that in the manufacturing process of chemical filters, a large amount of dust, debris and carbon ash residue will be generated in the filter material cutting, folding and assembly process. Currently, the industry generally uses brush cleaning and electrostatic adsorption, which cannot effectively remove pollutants on the surface of chemical filters, and the styles are limited and cannot be adapted to multiple sizes of filters.
[0016] (2) By setting a limiting bracket on the filter placement platform, the chemical filter is fixed on the filter placement platform. The limiting bracket can be used to fix the filter, which can adapt to chemical filters with multiple structures and sizes, thus improving flexibility and applicability. Attached Figure Description
