Description

A kind of self-cleaning filter device
Technical field
The present invention relates to field of environment protection more particularly to a kind of self-cleaning filter devices.
Background technology
With the development of modern industry, dust is to the pollution getting worse of environment, there is an urgent need to administer dust pollution, at present Mostly it is to be dusted by pulse bag formula deduster, however, pulse blowing bag type dust precipitator is in dust removal process, pulse jet Can be slowly on the filter bag of sack cleaner be stained with dust layer by layer, the dust stratification that accumulates over a long period reduce efficiency of dust collection, it is therefore desirable to often Cleaning is dusted to filter bag surface, after dusty gas enters sack cleaner, particle is big, heavy dust is due to gravity Effect settle down, to fall into dust mouth, when passing through cloth bag, dust is made the gas containing relatively fine dust by detention Gas is purified, although existing pulse dust collector can remove strainer, the dust stratification on filter bag, its dust stratification degree cannot It is found in time, and dust stratification can excessively cause equipment to be difficult to clean, as cost of labor is higher and higher, the disposal costs of equipment It is higher and higher.
Therefore, for above-mentioned pulse dust collector the shortcomings that, need to further develop pulse dust collector technology.
Invention content
The present invention is directed to be to provide a kind of the shortcomings that being directed to above-mentioned existing pulse dust collector, a kind of self-cleaning mistake is provided Filter device.
Technical scheme is as follows, including:
Filter housing and the cloth bag layer being successively set on filter housing, strainer filtering layer, air exhausting device, pressure sensor, institute State filter housing bottom be equipped with discharge port, middle part be equipped with air intake, top be equipped with exhaust outlet, the strainer filtering layer, including:Filter Net, the handle of the fixing device for fixing strainer and setting on the securing means, the strainer filtering layer can be dismantled through handle, Strainer is facilitated to carry out dismounting cleaning or replacement, the air exhausting device, including:Exhaust blower and the exhaust duct being connect with exhaust blower.
Further, the discharge port is arranged in filter housing bottom center.
Further, the pressure sensor is warning lamp display alarm.
Further, the exhaust blower can carry out forward and reverse operation.
Further, the strainer in the strainer filtering layer is 1~5 layer.
Further, the strainer is metal screen, and sieve meshes are 30~70um.
Further, cloth bag layer mounting device is equipped in the filter housing.
Further, in the filter housing installation space of cloth bag layer can make cloth bag layer in cleaning or filtering not with filtering Shell contacts.
Self-cleaning filter device of the present invention, it is negative pressure to be arranged the pressure in filter housing by exhaust blower, makes filtering Shell import enters dusty gas, and the dust-filtering in dusty gas, then dust are discharged strainer filtering layer by discharge port, Middle cloth bag layer makes discharge gas meet emission request, strainer filtering layer to carrying out secondary filter by the gas in air exhausting device It can be dismantled and be separated by filtration through handle, facilitated strainer to carry out disassembly, cleaning or replacement, exhaust blower forward and reverse can be run, air draft Machine forward direction is run, and negative pressure is generated in filter housing, cloth bag is made to be filtered, and exhaust blower inverted running, filter housing generates positive pressure, is passed through The air-flow of exhaust blower clears up cloth bag, and the apparatus structure is simple, sealing effect and good dedusting effect.
Description of the drawings
Fig. 1 is a kind of self-cleaning filter device schematic diagram provided by the invention.
Specific implementation mode
Self-cleaning filter device provided by the invention, to keep the purpose of the present invention, technical solution and effect clearer, bright Really, developing simultaneously referring to the drawings, the present invention is described in more detail for embodiment.It should be appreciated that specific implementation described herein Example is not intended to limit the present invention only to explain the present invention.
Self-cleaning filter device provided by the invention, structure is as shown in Figure 1, include:
Filter housing 10 and the cloth bag layer 20 being successively set on filter housing 10, strainer filtering layer 30, air exhausting device 40, pressure Sensor 50,10 bottom of the filter housing are equipped with discharge port 11, and middle part is equipped with air intake 12, and top is equipped with exhaust outlet 13, described Strainer filtering layer 30, including:Strainer 31, the fixing device 32 for fixing strainer 31 and the handle 33 being arranged in fixing device 32, The strainer filtering layer 30 can be dismantled through handle 33, and strainer 31 is facilitated to carry out dismounting cleaning or replacement, the air exhausting device 40, including:Exhaust blower 41 and the exhaust duct 42 being connect with exhaust blower 41, wherein 20 pairs of cloth bag layer pass through in air exhausting device 40 gas Body carries out secondary filter, and discharge gas is made to meet emission request.
Specifically, filter housing 10 is discharged in 10 bottom center of filter housing, convenient for dust in the setting of the discharge port 11.
Specifically, the pressure sensor 50 is warning lamp display alarm, and when cloth bag layer 20 is stained with dust layer by layer, resistance Increase, the gas pressure through cloth bag layer 20 becomes smaller, and pressure sensor 50 is alarmed, and makes the dust on cloth bag layer 20 can be clear in time Reason reduces entreprise cost.
Specifically, the exhaust blower 41 can carry out forward and reverse operation, exhaust blower 41 is made to can be not only used for generating in filter housing 10 Negative pressure works, it can also be used to generate positive pressure in filter housing 10 and clear up cloth bag layer 20.
Specifically, the strainer 31 in the strainer filtering layer 30 is 1~5 layer.
Specifically, the strainer 31 is metal screen, and sieve meshes are 30~70um, make to be selected according to actual demand Filter screen mesh improves production efficiency.
Specifically, being equipped with cloth bag layer mounting device 14 in the filter housing 10.
Specifically, in the filter housing 10 installation space of cloth bag layer 20 can make cloth bag layer 20 in cleaning or filtering not with Filter housing 10 contacts.
In conclusion a kind of self-cleaning filter device provided by the present invention, by exhaust blower by the pressure in filter housing Row is negative pressure, so that filter housing import is entered dusty gas, strainer filtering layer is by the dust-filtering in dusty gas, and then dust is logical Discharge port discharge is crossed, wherein cloth bag layer makes discharge gas meet discharge to carrying out secondary filter by the gas in air exhausting device It is required that strainer filtering layer can be dismantled and be separated by filtration through handle, facilitate strainer progress disassembly, cleaning or replacement, exhaust blower can Forward and reverse operation, the operation of exhaust blower forward direction, filter housing is interior to generate negative pressure, and cloth bag is made to be filtered, exhaust blower inverted running, filtering Shell generates positive pressure, is cleared up cloth bag by the air-flow of exhaust blower, and the apparatus structure is simple, sealing effect and dedusting effect Fruit is good.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description, And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
