Description
Technical field
The utility model relates to a kind of air cleaner for equipment such as air compressor machines, belongs to the air filtration technical field.
Background technology
Air compressor machine (air compressor) is a kind of equipment that compressed gas source is provided, very extensive in industrial application, convert the pressure energy of gas to by the mechanical energy of prime mover (normally motor), preserve after having certain pressure after the air pressure of suction is shortened into, discharged by pipeline by exhaust outlet during use.If contain grit in the intake air, will the running gear of air compressor be caused damage, reduce air compressor service life, therefore, the air that enters air compressor all will filter, filter meticulousr, better to the protection of air compressor.
Existing air cleaner mainly contains two kinds of versions, i.e. self-cleaning strainer and leaf filter.Self-cleaning air filter is generally the Integral box structure, structural strength is high, good airproof performance, mainly formed by casing, magnetic valve, filter cylinder, Venturi tube and playpipe, be provided with filter cylinder in a row in the casing, filter out dust by filter cylinder in the air flow process, along with the dust that adsorbs on the efficient filter core increases, the inside and outside differential pressure of air stream of filter cylinder of flowing through can progressively increase, when this pressure reduction during greater than a certain setting value, magnetic valve recoils to filter cylinder with the injection of compressed air by Venturi tube within the extremely short time and blows, and is adsorbed in laying dust on the filter cylinder with removing.But also there is following defective in self-cleaning strainer: whole is Welding Structure, and volume is larger, transportation, installation and inconvenient maintenance; Be to realize blowing function, the filter cylinder precision is lower, and the smallest particles diameter of actual filtration is greater than 3 microns, and filtering accuracy can reduce gradually along with the operation of equipment, thereby has increased the frequency of maintenance of the equipment such as air compressor machine, has strengthened operating cost.Panel air filter is to make filtrate with the special glass fiber, makes filtering module, and filtering module is inserted in the housing of being made by sheet metal.It is capable of washing that panel air filter has filtrate, Reusability, good, the poly-dirt rate high of anti-dust performance, but also there is following defective: service life is shorter, and normal life cycle is 2000-3000 hour, changes frequently, and cost is high.
Chinese patent literature CN1390619 discloses a kind of " self-cleaning differential pressure centrifugal filter ", and CN1164346C discloses a kind of " automatic backwashing filter ", and still there is the defective of existing self-cleaning strainer in these two kinds of filters from its structure.
Present self-cleaning strainer and leaf filter all are independent uses, and the defective of self can't overcome.
Summary of the invention
The utility model according to Van der Waals force principle between the molecule, provides split type three grades of air cleaners of a kind of long service life, good filtration effect for the problem that existing air cleaner exists.
Split type three grades of air cleaners of the present utility model are by the following technical solutions:
Two parts before and after this filter is divided into, every part all includes a casing and a support, and anterior casing is installed on the front carriage, and the rear portion casing is installed on the posterior bracket, and screen pack is housed around the periphery of front carriage; The bottom-open of anterior casing and reach the end face sealing all around, be provided with in the anterior casing its inside is divided into up and down two-part base plate, the cavity on base plate top is air-purifying chamber, the bottom of base plate is equipped with filter cylinder, and corresponding filter cylinder has the hole on the base plate, and Venturi tube is installed directly over each filter cylinder, be provided with shower nozzle directly over the Venturi tube, nozzle connecting is connected on the air jet pipe, and air jet pipe is connected with gas receiver, and magnetic valve all is installed on the air jet pipe; The rear portion casing is closed structure, and filtering module is installed in it, and the air-purifying chamber in the front cavity of filtering module and the anterior casing is communicated with, and the rear cavity side of filtering module is provided with gas vent.
Be provided with dividing plate between the described filter cylinder, in case filter cylinder pollutes mutually when blowback is self-cleaning.
Be being connected of to dismantle between anterior casing and the front carriage and between rear portion casing and the posterior bracket.
During above-mentioned split type three grades of air cleaners operation, the air intake of air compressor machine and the gas vent of rear portion casing are linked together, start air compressor machine, extraneous air passes through the air-purifying chamber of the filter cylinder in the filter screen on the front carriage, the anterior casing, anterior casing internal upper part and the filtering module in the casing of rear portion successively, descending to airborne impurity, by thick to the filtering of essence, enter air compressor machine by gas vent at last.This kind design is not only considered the transportation, easy to installation and maintenance of equipment, and realizes easily the device upgrade transformation of using separately self-cleaning strainer or leaf filter to existing.
The utility model organically combines the filter elements such as filter screen, filter cylinder and filtering module, has not only prolonged the service life of filtering components and parts, has reduced replacement frequency, and filtering accuracy is high, can reach 0.3 micron, filter efficiency reaches 99.9%, and is safe and reliable.
