Technical Field

The invention relates to the technical field of transverse cutting units, in particular to an air inlet filtering device of a transverse cutting unit.

Background

The crosscut unit includes crosscut buttress pallet, and the head of crosscut buttress pallet is equipped with the fan, nevertheless because the fan can produce dust and dust etc. unavoidably at the during operation, consequently, the inside deposition of fan is more. In general, a machining plan with high surface requirements can be met only by disassembling and cleaning the fan. However, the time for disintegration and cleaning is not long, and dust is easy to accumulate in 1 month. In addition, the disassembly and cleaning difficulty is high, the downtime is long, and generally, the disassembly and cleaning of each fan needs more than 8 hours.

At present, the utility model patent of patent application number 201220468146.5 discloses a dust filter equipment, including the intake pipe of connecting the part that admits air, the inner wall of intake pipe is provided with the layer that absorbs water that absorbs steam, and the inner chamber of intake pipe is provided with the protection screen cloth that prevents dust, dust part that admits air. Through setting up protection screen cloth and the layer that absorbs water, with air filtration before the air admission, reduced pneumatic element's damage.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides an air inlet filtering device of a transverse cutting unit.

In order to solve the technical problem, the invention is solved by the following technical scheme:

the air inlet filtering device of the transverse cutting unit comprises a bracket and a filter screen, wherein the bracket is arranged at an air inlet of a fan, and the filter screen is fixed on the bracket; the support comprises an upper support and a lower support, the upper support is fixedly connected with the upper support and the lower support through bolts by a cross rod and two side rods, two sides of the filter screen are respectively fixedly connected with the upper support and the lower support, and the lower support is fixedly connected with the cross rod and the two side rods through bolts; the support includes preceding air inlet, back air inlet and four side air inlets, and the back air inlet communicates with the air inlet of fan, and the filter screen setting is on preceding air inlet and four side air inlets, and the filter screen is the fold form.

Preferably, the filter screen is provided with filter holes, and the aperture of the filter holes is 0.01-0.5 mm. Through the aperture of adjustment filtration pore, can be when satisfying the maximum air input of fan, can keep off the dust outside the filter screen or adsorb on the filter screen to the at utmost again, reduce the inside dust accumulation of fan.

Preferably, the area of the filter screen arranged at the front air inlet is 2-4 times of that of the front air inlet; the area of the filter screens arranged at the four side air inlets is 2.5-5 times of the area of the side air inlets. In order to install the filter screen of this area scope in the support, will increase the fold of filter screen by necessity to increase the area of taking a breath, satisfy the demand of the maximum air input of fan.

Due to the adoption of the technical scheme, the invention has the remarkable technical effects that:

the filter screen bracket is simple in structure, the cross rods and the vertical rods on the bracket are fixedly connected through bolts, so that the filter screen bracket is convenient to disassemble and assemble, and a filter screen can be replaced; the air inlet can be ensured to be clean to the maximum extent by regularly replacing the filter screen; 5 independent filter screens are arranged in the bracket, so that the replacement is very convenient, and the replacement can be completed in about 2 minutes. The bracket is of a cuboid frame structure, is convenient to disassemble, and can be disassembled by screwing the bolt for replacing the filter screen; the filter screen is provided with folds, so that the ventilation area can be increased, and the requirement of the maximum air inflow of the fan is met; meanwhile, the aperture of the filter hole can meet the requirement of the maximum air inflow, and dust can be blocked outside the fan to the maximum extent.
