The casing 1 is also provided with an air outlet hole 6 for supplying air from the air outlet 31 of the fan. The top of the casing 1 is provided with mounting lugs 7, which is convenient for hoisting and installation.

The present invention is a horizontal flat cloth cylinder dust collector designed for grain storage and transportation equipment. A plurality of multi-air duct cage frameworks 21 are arranged in the dust removal chamber. The multi-air duct cage framework 21 has a plurality of Independent air duct, large dust removal and filtration area, the gas blowback chamber set on the side of the dust removal chamber, directly provides high-pressure gas from the high-pressure air bag 15, and forms a high-pressure pulse air flow through the control of the electromagnetic pulse valve 16, from the high-pressure gas injection pipe 20 high-pressure gas blowing holes are blown back into the dust removal chamber for dust cleaning, the pressure of the blowing air flow is large and stable, and the control is convenient. The high-speed air flow in each air duct does not affect each other. The cloth tube 19 or the dust removal bag forms a closed channel around. During the process of blowing and cleaning the dust attached to the flat cloth tube 19, since each air chamber does not affect each other, at the moment of high-speed air jetting, the corresponding flat of each air chamber The same expansion and vibration effect can be obtained for the cloth drum 19, thereby avoiding the phenomenon of large expansion and vibration range in the middle and small expansion and vibration range on both sides and uneven cleaning effect, so that the cleaning effect is more uniform, and the filtration and cleaning efficiency are improved. The flange 26 is connected, the installation is simple and easy to operate, and it is convenient for the fixing and sealing of the flat cloth tube 19. Within a certain volume, the flat cloth tube 19 supported has a large filtering area, and the installation method is flexible, and can be installed horizontally and vertically; A dust collection room is set under the dust removal room, which can collect the dust blown and shaken off by the dust removal room, and transport it to the pressure door 32 by the screw conveyor. Because the dust removal room and the dust collection hopper connected with the dust removal room It is a negative pressure state, so the pressure door 32 is in a closed state. When the dust conveyed by the screw conveyor 17 is more, the dust extrusion force is greater than the negative pressure generated by the fan 14 sucking the pressure door 32, and the pressure door 32 is extruded by the dust. Open, the dust enters into the dust storage hopper 24 through the pressure door 32, when there is a lot of dust accumulated and collected in the dust storage hopper 24, the discharge door 25 can be opened to discharge the dust from the equipment, and the dust extrusion force in the screw conveyor 17 is less than the pressure When the door 32 is subject to the negative pressure generated by the fan 14 suction, the pressure door 32 is automatically closed. No matter in the closed state of the pressure door 32 or the state of the dust discharge when the pressure door 32 is opened, the dust collection chamber will not form a pressure relief for the dust removal chamber, so that The dust removal room always maintains a negative pressure for dust suction and filtration; a structurally reasonable connector 11 is arranged between the dismantled door panels 9, the sealing baffle 11-8 is located in the casing 14, and the fastening splint 11-3 is located outside the disassembled door panel 9. The tightening of screw rod 11-1, first nut 11-2 and second nut 11-7, sealing baffle plate 11-8 and fastening splint 11-3 will seal and fix adjacent dismounted door panels 9 together, and The second nut 11-7 located outside the casing 1 is fitted with a nut protective sleeve 11-5 with anti-skid lines 11-6, which can be quickly disassembled by hand directly without using a wrench. The invention is suitable for storage and conveying equipment in the grain industry, and is easy to install, has a good dust removal and stabilization effect, has high cleaning efficiency for the attached dust, is convenient and quick to collect dust, and does not affect the dust removal and filtration in the dust removal room at the same time.
