Abstract
The utility model discloses a blowback type air filter, which comprises a filter drum provided with a drum bottom on the lower end and sleeved with a hoop stent outside, and a plurality of circle airflow cutting discs; wherein, the outer edges of the airflow cutting discs are fixed on the inner wall of the filter drum; the diameter of the lower airflow cutting discs is smaller than the diameter of the upper airflow cutting discs; the filter drum takes a shape of a big-top-but-small-bottom inverse taper. The utility model has advantages of a good stemming-removing effect, long period of usage, and being more particularly suitable for the equipments such as air compressors, air blowers, air separators and other means to filter dust particles in air.
Description
(1) technical field
The utility model relates to a kind of filter that is used for filtering air dust particle.Be applicable on the equipment such as air compressor, air blast or air separation.
(2) background technology
Be the airborne dust of filtering, the air inlet place on the equipment such as air compressor, air blast or air separation generally all is equipped with filter.This filter is made of cylindric papery filter cylinder and the spider that is enclosed within this filter cylinder outside, and air is after tube filters after filtration during work, and dust particle wherein is by filtering, and clean air is drawn from the oral area of cartridge filter.Time one is long, and airborne dust particle can stop up the micropore on the cartridge wall, and reduces its filter effect.For removing the dust particle that is blocked in the cartridge filter micropore, method commonly used is to adopt the blowback air-flow with certain pressure that cartridge filter is carried out blowback.But because airless modulating device in the cartridge filter, it is very little to make that the blowback air-flow passes through the entrance angle of cartridge filter.Entrance angle one is little, and resistance is just big.Resistance one is big, and the thrust that affacts on the tamper is just little.Thrust one is little, and the effect of removing tamper is just poor.Therefore, the service life of cartridge filter is not long, needs often to change.
(3) summary of the invention
The purpose of this utility model is to provide a kind of back flushing type air cleaner.This back flushing type air cleaner, effective, the long service life of removing tamper.
Above-mentioned purpose of the present utility model is realized by following technical solution:
Back flushing type air cleaner of the present utility model comprises cartridge filter, and at the bottom of the lower end of cartridge filter had tin, its outside was with spider.Its design feature is to have some air-flows to cut dish in the cartridge filter, and this air-flow is cut dish for circular, and their outer edge is fixed on the inwall of cartridge filter.Wherein, following air-flow is cut the dish internal diameter and is cut the dish internal diameter less than top air-flow.
For further improving the blowback effect, can adopt up big and down small back taper cartridge filter.
Adopt such scheme, have the following advantages:
Because back flushing type air cleaner of the present utility model, some annular air-flows are installed in its cartridge filter cut dish, and following air-flow is cut the dish internal diameter and cut the dish internal diameter less than top air-flow.When cartridge filter being carried out blowback with the blowback air-flow, the air-flow that enters in the cartridge filter is divided into two parts after air-flow is cut the dish modulation, a part is still downward, the upper surface that another part is then cut dish along air-flow flows to the inwall of cartridge filter, and the entrance angle that makes a part of blowback air-flow pass through cartridge filter increases.Entrance angle one is big, and resistance is just little.Resistance one is little, and the thrust that affacts on the tamper is just big.Thrust one is big, and the effect of removing tamper is all right.The effect one of removing tamper is good, does not just need often to change cartridge filter, thereby has prolonged the service life of cartridge filter.
(4) description of drawings
Accompanying drawing is a back flushing type air filter arrangement schematic diagram of the present utility model.
(5) specific embodiment
As shown in drawings, back flushing type air cleaner of the present utility model comprises a cartridge filter 3, and the outside of this cartridge filter is with spider 4, and at the bottom of its lower end has tin 5, the upper end is uncovered shape.Said cartridge filter 3 is the papery filter cylinder, and it is to be bonded on the spider 4 with filter paper and to form.Be provided with some (in the present embodiment being 5) air-flow in the cartridge filter 3 and cut dish 1, this air-flow is cut dish for circular, and its inside edge is higher than outer edge.Wherein, following air-flow is cut dish 1 internal diameter and is cut dish 1 internal diameter less than top air-flow successively.
During work, after blowback air-flow 2 enters cartridge filter 3, cut dish 1 by air-flow and cut into two parts, a part continues descending, and another part changes flow direction back and blows away to the barrel of cartridge filter 3 with bigger entrance angle and fast speeds.
Claims (2)
1. the back flushing type air cleaner comprises cartridge filter (3), and at the bottom of cartridge filter (3) lower end has tin (5), its outside is with spider (4); It is characterized in that having in the cartridge filter (3) some air-flows to cut dish (1), this air-flow is cut dish for circular, and their outer edge is fixed on the inwall of cartridge filter (3); Wherein, following air-flow is cut dish (1) internal diameter and is cut dish (1) internal diameter less than top air-flow.
2. back flushing type air cleaner according to claim 1 is characterized in that cartridge filter (3) is up big and down small back taper.
