detailed description

Embodiment, referring to Fig. 1, the novel stand-alone pulse type filter cartridge 11 dust remover provided by the utility model, it comprises dust remover casing 1 and cleaning device 2, and described cleaning device 2 comprises air storage cylinder 21, and with storage cylinder 21 connected to the blowing pipe 22, the solenoid valve 23 is provided between the air storage cylinder 21 and the blowing pipe 22, the air storage pressure of the air storage cylinder 21 is 0.5-0.6MPa; the middle and lower part of the dust collector box 1 is provided with A plurality of filter cartridges 11, a plurality of filter cartridges 11 are vertically fixed in the dust collector box 1 through a lower fixing plate 12; a venturi tube 13 is arranged directly above the filter cartridge 11, and the height of the venturi tube 13 is Less than or equal to 150 mm, the lower end surface of the venturi tube 13 extends into the filter cartridge 11 at 10 mm, and the blowing pipe 22 directly above the venturi tube 13 is provided with a blowing port 24, and the lower end face of the blowing port 24 The vertical distance from the lower fixing plate 12 is 150 mm; the reason why the cleaning effect of the existing stand-alone pulse type filter cartridge 11 dust collector is not satisfactory due to the unsatisfactory cleaning effect is the compressed air injected into the filter cartridge 11 per unit time during backflushing The amount is small and the pressure is not large enough. The utility model increases the gas storage pressure of the cylinder from the current 0.4MPa to 0.5-0.6MPa by increasing the gas storage capacity of the gas storage cylinder 21. The pipe 13 increases the gas volume and gas velocity in the blowing process to solve the unsatisfactory problem of dust removal effect.

Described ash cleaning device 2 also comprises centrifugal blower external discharge mechanism 25, and described centrifugal blower external discharge mechanism 25 comprises centrifugal blower 26, and exhaust pipe 27, and described centrifugal blower 26 is arranged on an upper fixed plate 14 above air spray pipe On the side of the air storage cylinder 21, the distance between the upper fixed plate 14 and the lower fixed plate 12 is 200 mm, the exhaust pipe 27 communicates with the centrifugal fan 26 through a wind guide hood 28, and the exhaust pipe 27 is vertical It is arranged on the upper part of the dust collector box 1 , and the upper nozzle of the exhaust pipe 27 extends out of the upper surface of the dust collector box 1 . The diameter of the exhaust pipe 27 is 250 mm. In this embodiment, a centrifugal fan external discharge mechanism 25 is provided, and the exhaust pipe is directly connected with the centrifugal fan 26, and the fan exhaust is led to the top of the dust collector equipment, and discharged to the outside of the equipment, thereby solving the dust accumulation phenomenon in the fan box, and the new type The stand-alone pulse filter cartridge dust collector has a compact structure.

The air guide cover is provided with a dust detection sensor. When the dust detection sensor detects that there is dust in the air guide cover, the dust detection sensor sends a signal to the controller, and the controller controls the centrifugal fan to increase the power to run for a period of time, and will The accumulated dust in the air hood is blown out to the outside of the dust collector to prevent more dust from accumulating in the air guide hood.

The working principle of the utility model: when the dust collector is cleaning dust, under the action of the IC controller, the solenoid valve is opened, and the compressed air is ejected from the injection port of the cylinder. When the air flow passes through the venturi tube, the air volume and speed are increased. The principle of the venturi tube is to change the air flow from thick to thin to speed up the gas flow rate, so that the gas forms a "vacuum" area on the back side of the venturi tube outlet. When cleaning the filter cartridge, when the high-speed air flow passes through the Venturi tube, the secondary air that is 5-8 times larger than the blown compressed air is induced to enter the filter cartridge, causing the filter material to expand rapidly instantly. Due to the reverse effect of the air flow, the accumulated The dust on the filter material falls off. The Venturi tube greatly improves the intensity and effect of pulse injection, reduces the amount of compressed air, and saves energy.

In this embodiment, the size of the fan box is increased, and a set of non-standard wind guide cover is added at the air outlet of the centrifugal fan to guide the fan exhaust to the exhaust pipe above the equipment, thereby solving the phenomenon of dust accumulation in the fan box.
