Abstract
The invention belongs to the technical field of filtering devices and particularly relates to a dust filtering device which comprises an air inlet, a bending pipe, an air outlet and a filtering mechanism. An outlet at the short end of the bending pipe is the air inlet, an outlet at the long end of the bending pipe is the air outlet, and the filtering mechanism is arranged at the short end of the bending pipe. An activated carbon filtering screen is arranged in the air outlet. By means of unitization of the filtering mechanism of the filtering device, disassembly and washing of the filtering screen can be slightly achieved. A first filtering screen and the second filtering screen are fixed on the support frame by arranging the support frame in the filtering mechanism, and the filtering screen is not easy to deform. A single filtering screen is changed into a double-layer filtering screen structure with the first filtering screen and the second filtering screen, and filtering effect is better. The dust filtering device achieves the effect of secondary filtering by arranging the activated carbon filtering screen at the air outlet.
Description
Technical field
The invention belongs to the filter technical field, particularly relate to dust filtering device.
Background technology
At present, dust filtering device plays an important role in industrial particularly chemical industry.Usually screen pack is arranged on equipment inner wall in the prior art, such structure is long-time use after not only screen pack easily be out of shape, dismounting and clean also very difficultly is difficult to the filter effect that reaches good.
Summary of the invention
Technical problem to be solved is to overcome the defective that prior art exists, provide a kind of filter screen not yielding, be convenient to the dust filtering device dismantling and clean.
The technology used in the present invention solution comprises air inlet, bend pipe, exhaust outlet and filter mechanism, and the outlet of bend pipe short end is air inlet, and the outlet of bend pipe long end is exhaust outlet, and the bend pipe short end is provided with filter mechanism.
Be provided with active carbon filter screen in the described exhaust outlet.
Described filter mechanism comprises top cover, base, sealing gasket, support bar, bracing frame, the first filter screen and the second filter screen, filter mechanism is tightly connected by sealing gasket and bend pipe, be provided with support bar in the filter mechanism, the support bar lower end is provided with base, bracing frame is connected with support bar, bracing frame is provided with the first filter screen and the second filter screen, and post upper is provided with top cover.
Be provided with rubber cushion on the described base, base closely is connected with elbow internal wall by rubber cushion.
Compared with prior art, the beneficial effect that the present invention has is: 1. the present invention can easily realize dismounting and cleaning to filter screen by making the filter mechanism blocking of filter;
2. the present invention is fixed on the first filter screen and the second filter screen on the bracing frame by bracing frame is set in filter mechanism, can make filter screen be difficult for occuring deformation.
3. the present invention makes filter effect better by single filter screen being changed over the two-layer filter structure of the first filter screen and the second filter screen.
4. the present invention reaches the effect of secondary filter by at exhaust outlet active carbon filter screen being set.
