Description
Technical field:
The utility model relates to a kind of time sequential pulse self-cleaning type air cleaner, can be extensively and air compressor, Blower for sucking or supplying, high-horsepower diesel engine, gas engine etc. various with the supporting use of wind devices, belong to the air filter unit technical field.
Background technology:
Before the utility model is made, in prior art, normally adopt some groups of filter cores to form with air compressor, Blower for sucking or supplying, diesel engine and gas engine etc. are various with the matching used air cleaner of wind devices, though it is too huge that this kind structure has overcome volume, the shortcoming that applicability is relatively poor, but its air filtration precision is not high enough, and performance is stable inadequately, and backwash effect is relatively poor.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of compact conformation, reasonable is provided; Volume is little, and low cost of manufacture can make up arbitrarily; Air filtration precision height, dependable performance, backwash effect is good, can guarantee the time sequential pulse self-cleaning type air cleaner with the long-term non-stop run of wind devices.
Main solution of the present utility model is achieved in that
The utility model mainly adopts in casing 2 accumulator 4 is installed, two accumulators 4 join together mutually by cross over pipe 12, filter element 10 is pressed on the sealing strip 8 in the casing 2, pulse valve/electromagnetic valve component 13 connects cross over pipe 12 by coupling nut 14 with bar shaped nozzle 15, the bar shaped nozzle is fixed on the accumulator 4 by connecting rack 7.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, rationally; Volume is little, and low cost of manufacture can make up arbitrarily, the automaticity height; Air filtration precision height, stable performance, reliable, backwash effect is good, it is various with the supporting uses of wind devices being particularly suitable in the frequent area that takes place of sandstorm, can guarantee with the long-term non-stop run of wind devices.

The specific embodiment:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of flange 1, casing 2, time sequential pulse controller 3, accumulator 4, inlet suction port 5, little differential pressure sensor 6, connecting rack 7, efficient filter core 10, set bolt 11, cross over pipe 12, pulse valve/electromagnetic valve component 13, coupling nut 14, bar shaped nozzle 15 etc.The utility model casing 2 is a square structure, is connected to on the admission line of wind devices by adpting flange 1.According to what of air quantity.Can be by connecting screw 16 with 2-4 filter unit sports association integrator.Generally speaking, a filter unit body can satisfy a requirement of using air quantity with wind devices; High strength, high efficiency particulate air filter filter core 10 are quadra structures, are pressed on the sealing strip 8 by the bolt 11 that is fixed and clamped, sealed loop-pad 9, seal very reliable.Accumulator 4 is installed in the casing 2.Accumulator 4 be two columnar structured, join together mutually by cross over pipe 12, its volume is enough to store a certain amount of compressed air, guarantees the energy of pulse backwashing and the effect of backwash.The number of frame-type filter core length L decision pulse valve/electromagnetic valve component 13 generally is designed to the 10-12 group.This is enough to satisfy general medium-sized needs with the wind devices gas consumption.Pulse valve/electromagnetic valve component 13 is linked together cross over pipe 12 and bar shaped nozzle 15 by coupling nut 14, and bar shaped nozzle 15 is fixed on the accumulator 4 by connecting rack 7 simultaneously.The length of bar shaped nozzle 15 is slightly less than the width of efficient filter core 10, simultaneously, is shaped on the plurality of rows spray-hole facing to filter core 10 directions on the bar shaped nozzle 15, and is 90 degree angles, can wash the wide filter core band of 50-70mm when guaranteeing every row's nozzle pulse backwashing.Pulse valve/electromagnetic valve component 13 is by time sequential pulse controller 3 its On/Off of control.The utility model time sequential pulse controller logic block diagram is as shown in Figure 3: adopt pulse signal generator (T1 control) to connect pulse-width controller (T2 control), pulse distribution decoder, electronic switch, pulse valve/magnetic valve and counter respectively, counter connects the pulse distribution decoder, and the pulse distribution decoder is connected power supply.
The course of work of the present utility model is as follows:
Contain the dust air through inlet inflow filter casing, after efficient filter core 10 filters, enter through connecting flange 1 again and use wind devices.After work after a time, when foreign material such as dirty airborne dust were adsorbed onto a certain setting value of filter core filter, little differential pressure sensor 6 promptly sent a triggering signal to time sequential pulse controller 3, and time sequential pulse controller 3 is promptly started working after receiving this triggering signal.Time sequential pulse controller 3, little differential pressure sensor 6 and inlet suction port 5 are installed on the casing 2, and it has sequential ground, continuously sends the ON/OFF signal to pulse valve/electromagnetic valve component 13, and control 1#-n# pulse valve/electromagnetic valve component carries out work successively.When pulse valve/electromagnetic valve component 13 instantaneous opening, compressed air in the accumulator 4 sprays to the filter core direction through cross over pipe 12-pulse valve/electromagnetic valve component 13-bar shaped nozzle 15, owing on the surface in the paper outside, cause efficient filter core inside and outside differential pressure Δ Pa to increase gradually.This strength very strong (air velocity is greater than 500m/s) of pulse backwashing not only of compole short (being generally 30-80ms) when pressure differential deltap pa opens greater than pulse valve, developing result is good, and compressed-air actuated consumption seldom (is generally less than 0.05NM
3/ min).Under the control of time sequential pulse controller 3, pulse valve/pulse valve assembly 13 begins to work successively from 1#, and filter core 10 is carried out the backwash of automatic circulation type by row, to remove the dust stratification in the filter core outside.After the backwash that circulates repeatedly through several times, the dust stratification major part on the filter core is eliminated, and the filter core inside and outside differential pressure returns to normal level, and whole cleaning process promptly stops automatically.
