Abstract

The utility model provides a noise reducing self-cleaning style air filter group. The utility model comprises a supporting leg, a front-arranged filter, a pulsed back blowing dust cleaning system, a PLC self-controlled/ hand-controlled control box and an air filter group, wherein the air filter group is installed on the supporting leg, the air filter group mainly comprises an air inlet, a box body of a purified air outlet and an air filter which is arranged in the box body and composed of a cylinder, a venturi pipe and a filter cartridge, wherein a self-cleaning nozzle is arranged on an outlet of each air filter, the pulsed back blowing dust cleaning system is arranged on the position which is outside the box body and corresponded with the filter cartridge, the pulsed back blowing dust cleaning system is connected with an exhalant of compressed air, the front-arranged filter is arrange on the outside of the supporting leg, a perforated plate is installed in the box body, and a noise reducing layer is arranged between the perforated plate and the box body. The utility model has simple and rational technical scheme, and can eliminate noises which are produced by a draught fan inlet and integrate the air filter and noise reducing equipment into integrity.

Description

Noise reduction self-cleaning type air filtration unit
(1) technical field
The utility model relates to a kind of air cleaning unit, is specifically related to a kind of noise reduction self-cleaning type air filtration unit.
(2) background technology
In the prior art, known air filter machine all is cabinets that have air intlet and net air outlet, air cleaner is arranged in cabinet and be used for self-cleaning self-cleaning shower nozzle, and electric controller.But the cabinet of the preposition air filter machine of existing blower fan does not all have silencing means, can't eliminate at cabinet inside by the noise that fans entrance produces, noise sees through cabinet and spreads out of, have a strong impact on surrounding environment, can eliminate the noise that produces by fans entrance and before fans entrance, increase muffler, but increase cost when adding muffler equipment complexity, and the noise in the cabinet can't be eliminated still.At present also there is not to carry the air filter machine of muffling device.
(3) summary of the invention
The purpose of this utility model is to provide a kind of technology simple, rationally, can eliminate the noise that is produced by fans entrance and make air filter machine and noise reduction self-cleaning type air filtration unit that muffling device combines together.
The purpose of this utility model is achieved in that it comprises supporting leg, fore filter, the pulse backblowing soot cleaning system, PLC automatic control/manual control cabinet and air filtration unit, the air filtration unit is installed on the supporting leg, the air filtration unit mainly includes the casing of air intlet and net air outlet, with in the casing by cylinder, the air cleaner that Venturi tube and cartridge filter are formed, in the exit of each air cleaner self-cleaning shower nozzle is arranged, the pulse backblowing soot cleaning system is arranged on the position of the corresponding filter cylinder in the casing outside and connects compressed air and goes out pipe, fore filter is arranged on a leg outer side, in the described casing porous plate is installed, is provided with the noise reduction layer between porous plate and the casing.
The utility model also has some technical characterictics like this:
1, described noise reduction layer is glass silk flosssilk wadding or heat-preservation cotton;
2, described fore filter is made up of aluminum alloy frame and 18 order stainless (steel) wires sliding door.
The utility model is the equipment that great net air is provided for air compressor.Air is through fore filter, after big dust particle, tree hair, leaf are separated, reaches the air filtration purpose filtering out fine dusts through filter cylinder.Be increased to when quantitative when filter cylinder contains grey resistance, PLC robot control system(RCS) control impuls valve utilizes compressed air grouping blowback filter cylinder, make filter cylinder around dust fall clearly.When filtering the noise reduction layer that wind adds by the casing periphery in casing the time with compression fan generation noise noise is disappeared.The utility model has been installed the noise reduction layer that is made of glass silk flosssilk wadding or heat-preservation cotton in the casing of air filtration unit, by porous plate the noise reduction layer is fixed, the noise reduction layer of box house can be finished the sound deadening that is produced noise by preposition fans entrance, make air filtration and the noise reduction product that becomes one, replace the muffler before the fans entrance.In addition, the utility model cost is low, and technology is simple, rationally, and fore filter can reduce filter cylinder and filter dust quantity, deashing number of times, filter efficiency and reach 99.9%, and the noise reduction of noise reduction casing can reach 30Db (A), makes air filtration and noise reduction two-in-one.Noise reduction self-cleaning air filter efficient height, volume is little, noise is low, it is big to filter air quantity.
(4) specific embodiment
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is Fig. 1 side view;
Fig. 3 is the structural representation of casing.
(5) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
In conjunction with the accompanying drawings, present embodiment comprises supporting leg 1, fore filter 2, pulse backblowing soot cleaning system 3, PLC automatic control/manual control cabinet and air filtration unit, the air filtration unit is installed on the supporting leg 1, the air filtration unit mainly includes the casing 4 of air intlet and net air outlet, interior with casing 4 by cylinder 5, the air cleaner that Venturi tube 6 and cartridge filter 7 are formed, in the exit of each air cleaner self-cleaning shower nozzle is arranged, pulse backblowing soot cleaning system 3 is arranged on the position of the corresponding filter cylinder in the casing outside and connects compressed air and goes out pipe, fore filter 2 is arranged on supporting leg 1 outside, in the described casing 4 porous plate 8 is installed, be provided with noise reduction layer 9 between porous plate 8 and the casing 4, noise reduction layer 9 is glass silk flosssilk wadding or heat-preservation cotton; Fore filter 2 is made up of aluminum alloy frame and 18 order stainless (steel) wires sliding door.
