Description
Technical field
The utility model relates to a kind of air filter unit, is specifically related to a kind of pocket type air filter.
Background technology
Pocket type air filter is widely used in industrial production, is easy to safeguard because it is simple in structure, has obtained in actual use favorable comment widely.Existing pocket type air filter is constituting by filter bag frame and dust settling pocket mostly, and, the mode that existing pocket type air filter only adopts one deck filter bag to filter, its filter effect is limited, can not efficiently complete the air filtration operation that dust is more, particle is larger.
When air cleaner is when containing the larger air of more dust, dust granule, because dust stops up the pore of filter bag very soon, the air velocity of air cleaner is greatly reduced, make air cross filter efficiency and reduce, can not meet the requirement of high efficiency filter.And oarse-grained dust can block dust settling pocket very soon, be that air cleaner is lost work capacity.
So; in order to overcome the deficiency of existing air cleaner; need to design a kind of can high-efficient filter except bulky grain dust, solve the pocket type air filter of the air filtration difficult problem that amount of dust is large; to improve air cleaner for the filter efficiency of the air that contains bulky grain dust, a large amount of dusts; guarantee the efficient stable operation of air cleaner, improve efficiency of dust collection and dust removing effects.
Utility model content
The utility model technical issues that need to address are just to overcome the defect of prior art; a kind of pocket type air filter is provided; it can improve air cleaner for the filter efficiency of the air that contains bulky grain dust, a large amount of dusts; guarantee the efficient stable operation of air cleaner, improve efficiency of dust collection and dust removing effects.
For addressing the above problem, the utility model adopts following technical scheme:
Pocket type air filter, pocket type air filter is provided with cuboid filter bag frame, the left surface of filter bag frame is filter bag plate, filter bag plate is provided with for one-level filter bag ring and the secondary filter bag ring of filter bag are installed, on one-level filter bag ring and secondary filter bag ring, be separately installed with primary dust removing bag and two-stage dust removal bag, it is inner that primary dust removing bag is socketed on two-stage dust removal bag, when air passes through, most of air need pass through respectively primary dust removing bag and two-stage dust removal bag, has improved dust removing effects; The air channel in filter bag plate left side is provided with the metal otter board that upper end is tilted to the left, and the left side of metal otter board is provided with gauze parallel with metal otter board, and gauze can filter airborne larger particles dust, and the bulky grain dust being filled into moves downward to dust collecting trough; The lower end of metal otter board is provided with replaceable dust collecting trough; The air channel in metal otter board left side is provided with S shape deflector and measuring wind speed device, and S shape deflector changes the direction of motion by part air, blows, thereby the bulky grain dust on gauze is moved downward to dust collecting trough from the upper end of gauze to lower right.
The utility model is in order to improve the water conservancy diversion effect of deflector; improve the dust removing effects of gauze; preferably technical scheme is; S shape deflector horizontally set; S shape deflector is positioned at the middle and upper part in air channel, and the right-hand member of S shape deflector, higher than left end, has space between the right-hand member of S shape deflector and gauze; deflector, by the lead lower right motion of gauze of air-flow, blows away the bulky grain dust on gauze.
The utility model is in order to improve the dust removing effects of dust settling pocket, and preferably technical scheme also has, and two-stage dust removal bag inside is provided with 2 primary dust removing bags that are set up in parallel; The length of primary dust removing bag is 3/5 of two-stage dust removal bag length.
The utility model, in order to improve the circulation effect of air, reduces air drag, and preferably technical scheme also has, and metal otter board is provided with mesh, and gauze is fixed on the left surface of metal otter board.
The utility model is for can convenient collection and remove the bulky grain dust on gauze, and preferably technical scheme also has, and replaceable ash collection slot is provided with the clamping ring for being fixedly connected with air channel, and replaceable dust collecting trough can convenient changing and removed dust.
The utility model is in order further to improve the elementary filtration result for bulky grain dust, and preferably technical scheme also has, and gauze is 2～5 layers of structure.
The course of work of the utility model pocket type air filter is: air flows into from air channel, the air of middle and upper part, air channel is through deflector effect and direction is changed into lower right, gauze filters the bulky grain dust in air, along with the Air Flow of lower right, the bulky grain dust on gauze moves to ash collection slot to lower right; Air stream carries out filtration operation by dust settling pocket when primary dust removing bag and two-stage dust removal bag, has further improved filter effect, and measuring wind speed device can be measured the air velocity in air channel.
Advantage of the present utility model and beneficial effect are: the utility model pocket type air filter is provided with deflector and gauze, the bulky grain dust in can high-efficient filter deacration, and collected and ash collection slot in, improved air filter efficiency; The utility model pocket type air filter is provided with primary dust removing bag and two-stage dust removal bag, can improve air filtration effect, and most of air is carried out to twice filter bag filtration; The utility model pocket type air filter is provided with replaceable ash collection slot, can efficiently remove the bulky grain dust that gauze is collected.
