Abstract
Description
Technical Field
[0001] This utility model relates to the field of bag filter technology, and in particular to a bag filter with cleaning function. Background Technology
[0002] Baghouse dust collectors, also known as bag filters or bag dust collectors, have become the most widely used dust removal equipment with the advancement of modern research and development technology. They are suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, and utilize the filtration effect of fibrous fabric to filter dust-laden gas.
[0003] Common baghouse dust collectors only include cleaning functions, which can clean dust from the bags by blowing air or brushing. However, they lack the function of removing sticky contaminants, which cannot guarantee the filtration performance of the bags. This can easily lead to viscous liquids in the air sticking to the surface of the bags when filtering air, filling the gaps between the fibers. These viscous liquids cannot be removed by blowing air or brushing, thus affecting the filtration performance of the bags.
[0004] Therefore, in view of the problem that the above-mentioned bag dust collectors lack the function of removing sticky pollutants, and cannot effectively remove sticky pollutants from the surface of the filter bags, resulting in the blockage of fiber pores, reduced air permeability, and affected filtration efficiency, there is an urgent need to design a new type of bag dust collector with cleaning function. Utility Model Content
[0005] To overcome the problem that common baghouse dust collectors lack the function of removing sticky pollutants, and cannot effectively remove sticky pollutants from the surface of the filter bags, resulting in the clogging of fiber pores, reduced air permeability, and reduced filtration efficiency.
[0006] The technical solution of this utility model is as follows: a bag filter dust collector with cleaning function, including a dust collection box; it also includes an installation frame, a dust collection bag, a through hole, a hollow water distribution frame, a high-pressure spray nozzle, and a water supply hose. The installation frame is set at the top of the dust collection box, and the dust collection bag is set inside the installation frame. The dust collection bag is located inside the dust collection box. A through hole is opened at the bottom of the front left side of the dust collection box. A hollow water distribution frame is set at the bottom of the dust collection box. The top of the hollow water distribution frame is rectangular and has four high-pressure spray nozzles. A water supply hose is set at the left end of the front side of the hollow water distribution frame. The end of the water supply hose away from the hollow water distribution frame passes through the through hole and is placed outside the dust collection box.
[0007] Preferably, cleaning water is delivered to the interior of the hollow water distribution frame via an external water supply device through a water hose. At this time, the dust collection box is inverted, and the external sealing cover is removed. Then, the cleaning water in the hollow water distribution frame is sprayed out through a high-pressure spray nozzle. The sprayed cleaning water washes the dust collection bags. After being impacted by the water flow, the dust collection bags are pushed out from the interior of the dust collection box. The sticky contaminants on the surface of the dust collection bags are washed off by the water flow, so that the impurities inside the dust collection bags fall downward with the water flow. This achieves the function of removing sticky contaminants, which solves the problem of common bag dust collectors that only have a cleaning function. They can clean the dust on the bags by blowing air or brushing, but lack the function of removing sticky contaminants. This cannot guarantee the filtration performance of the bags. When filtering air, viscous liquid in the air can stick to the surface of the bags, filling the gaps between the fibers. The viscous liquid cannot be removed by blowing air or brushing, thus affecting the filtration performance of the bags.
[0008] Preferably, the dust collector has a left support leg on the left side and a right support leg on the right side.
[0009] Preferably, the right side of the left support leg is rotatably connected to a connecting shaft.
[0010] Preferably, the end of the connecting shaft away from the left support leg is rotatably connected to the left side of the dust collection box.
[0011] Preferably, a motor is installed on the right side of the right support leg, corresponding to the position of the connecting shaft.
[0012] Preferably, the output end on the left side of the motor is connected to the right side of the dust collector via the right support leg.
[0013] Preferably, an exhaust pipe is located at the center of the bottom of the dust collector, a water collection box is located at the bottom between the left and right support legs, and a drain pipe is located in the middle of the right side of the water collection box.
[0014] The beneficial effects of this utility model are:
[0015] 1. The external water supply equipment injects cleaning water into the hollow water distribution frame through the water supply hose. At this time, the dust collection box is inverted and the external sealing cover is removed. The cleaning water in the hollow water distribution frame is sprayed onto the surface of the dust collection bag through the high-pressure spray nozzle. The impact force of the water flow pushes the dust collection bag out of the dust collection box. The sticky pollutants on its surface are washed away and fall with the water flow. The impurities are discharged at the same time, and finally the dust collection bag is deeply rinsed and its filtration performance is restored. Attached Figure Description

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5This utility model provides an embodiment: a bag filter dust collector with cleaning function, including a dust collection box 1; it also includes an installation frame 2, a dust collection bag 3, a through hole 4, a hollow water distribution frame 5, a high-pressure spray nozzle 6, and a water supply hose 7. The installation frame 2 is provided at the top of the dust collection box 1, and the dust collection bag 3 is provided inside the installation frame 2. The dust collection bag 3 is located inside the dust collection box 1. A through hole 4 is provided at the bottom of the left front end of the dust collection box 1. A hollow water distribution frame 5 is provided at the bottom of the dust collection box 1. The top of the hollow water distribution frame 5 is rectangular and has four high-pressure spray nozzles 6. A water supply hose 7 is provided at the left end of the front side of the hollow water distribution frame 5. The end of the water supply hose 7 away from the hollow water distribution frame 5 passes through the through hole 4 and is placed outside the dust collection box 1. Cleaning water is delivered to the inside of the hollow water distribution frame 5 through the water supply hose 7 by an external water supply device. At this time, the dust collection box 1 is in an inverted state. The outer sealing cover is removed, and the cleaning water in the hollow water distribution frame 5 is sprayed out through the high-pressure spray nozzle 6. The sprayed cleaning water washes the dust collector bag 3. After being impacted by the water flow, the dust collector bag 3 is pushed out from the inside of the dust collector box 1. The sticky contaminants on the surface of the dust collector bag 3 are washed off by the water flow, so that the impurities inside the dust collector bag 3 fall down with the water flow, realizing the function of removing sticky contaminants. This solves the problem of common bag dust collectors, which only have the function of cleaning. They can clean the dust on the bag by blowing air or brushing, but lack the function of removing sticky contaminants. They cannot guarantee the filtration performance of the bag. When the bag filters the air, viscous liquid in the air sticks to the surface of the bag, which fills the gaps between the fibers. The viscous liquid cannot be removed by blowing air or brushing, thus affecting the filtration performance of the bag.
[0024] Please see Figures 2-5 In this embodiment, a left support leg 8 is provided on the left side of the dust collection box 1, and a right support leg 10 is provided on the right side of the dust collection box 1. The dust collection box 1 is supported by the left support leg 8 and the right support leg 10. A connecting shaft 9 is rotatably connected to the right side of the left support leg 8. When the connecting shaft 9 rotates, it will not drive the left support leg 8 to rotate because it is in a rotatable connection with the left support leg 8. The end of the connecting shaft 9 away from the left support leg 8 is rotatably connected to the left side of the dust collection box 1. When the dust collection box 1 rotates, it will drive the connecting shaft 9 to rotate.
[0025] Please see Figures 1-5In this embodiment, a motor 11 is provided on the right side of the right support leg 10 corresponding to the position of the connecting shaft 9. After the motor 11 is started, it will drive its output end to rotate. The output end on the left side of the motor 11 passes through the right support leg 10 and is connected to the right side of the dust collection box 1. The motor 11 drives the dust collection box 1 to rotate through the rotating output end until the top of the dust collection box 1 faces the ground, so that the dust collection box 1 is in an inverted state. An exhaust pipe 12 is provided at the center of the bottom of the dust collection box 1. A water receiving box 13 is provided at the bottom end between the left support leg 8 and the right support leg 10. A drain pipe 14 is provided in the middle of the right side of the water receiving box 13. The water after rinsing will fall into the interior of the water receiving box 13 and finally be discharged through the drain pipe 14.
[0026] During operation, the sealed cover with the air inlet is placed on top of the dust collector 1. Then, the water hose 7 is connected to the output end of the external water supply equipment. Subsequently, the gas containing impurities enters the interior of the dust collector 1 through the air inlet on the sealed cover. At this time, the impurities in the air are filtered by the dust collector bag 3. The filtered air is then discharged from the exhaust pipe 12, and the viscous liquid in the air will adhere to the surface of the bag. After the operation is completed, the motor 11 drives the dust collector 1 to rotate through the rotating output end until the top of the dust collector 1 faces the ground, thus putting the dust collector 1 in an inverted state. When the dust collector 1 rotates, it drives the connecting shaft 9 to rotate, and then the air is discharged through the external water supply equipment. The water supply equipment delivers cleaning water through the water hose 7 to the interior of the hollow water distribution frame 5. At this time, the dust collection box 1 is inverted and the outer sealing cover is removed. Then, the cleaning water in the hollow water distribution frame 5 is sprayed out through the high-pressure spray nozzle 6. The sprayed cleaning water washes the dust collection bag 3. After being impacted by the water flow, the dust collection bag 3 is pushed out from the interior of the dust collection box 1. The sticky contaminants on the surface of the dust collection bag 3 are washed off by the water flow, so that the impurities inside the dust collection bag 3 fall down with the water flow. The washed water flows down into the water receiving box 13 and is finally discharged through the drain pipe 14, thus realizing the function of removing sticky contaminants.
[0027] Through the above steps, cleaning water is delivered to the interior of the hollow water distribution frame 5 via an external water supply device and a water hose 7. At this time, the dust collector 1 is inverted, and the external sealing cover is removed. Then, the cleaning water inside the hollow water distribution frame 5 is sprayed out through the high-pressure spray nozzle 6. The sprayed cleaning water washes the dust collector bags 3. After being impacted by the water flow, the dust collector bags 3 are pushed out from inside the dust collector 1. The sticky contaminants on the surface of the dust collector bags 3 are washed off by the water flow, thereby making the dust collector bags 3... Impurities fall downwards with the water flow, thus removing sticky contaminants. This addresses the common problem of baghouse dust collectors, which only have a cleaning function, able to remove dust from the bags by blowing air or brushing, but lack the ability to remove sticky contaminants. This fails to guarantee the filtration performance of the bags, and can easily lead to viscous liquids in the air sticking to the surface of the bags during air filtration, filling the gaps between the fibers. These viscous liquids cannot be removed by blowing air or brushing, thus affecting the filtration performance of the bags.
