Description

Technical Field

[0001] This invention belongs to the technical field of baghouse dust collectors and relates to a cooling device for baghouse dust collectors. Background Technology

[0002] Baghouse dust collectors are dry dust filtration devices suitable for collecting fine, dry, non-fibrous dust. Currently, baghouse dust collectors typically lack cooling devices. If the temperature of the dust-laden gas is too high, the high-temperature dust entering the filter bags will accelerate the aging of the bags and may even cause spontaneous combustion, significantly reducing their lifespan. Furthermore, large dust particles carried by the high-temperature dust-laden gas can easily clog the bags, making cleaning difficult. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a cooling device for baghouse dust collectors. This device solves the problems that high-temperature dust entering the baghouse will accelerate the aging of the baghouse, and that large particles of dust carried in the high-temperature dust-laden gas will easily clog the baghouse, making it inconvenient to clean.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A cooling device for a bag filter dust collector includes a base and a dust collector body. The dust collector body is fixedly connected to the base. An air inlet pipe is provided at the lower end of the dust collector body, and an air outlet pipe is provided at the upper end of the dust collector body. A mounting plate is fixedly connected inside the dust collector body, and a plurality of dust filter bags are provided on the mounting plate. The device is characterized in that a cooling box is fixedly connected to the base, and a conveying channel is provided inside the cooling box. An air supply pipe is fixedly connected to one side of the cooling box, and the air supply pipe is connected to one end of the conveying channel. The other end of the conveying channel passes through the side wall of the cooling box and is connected to one end of the air inlet pipe. A sealing component is provided on the dust collector body to seal the other end of the air inlet pipe.

[0006] In the aforementioned bag filter cooling device, the sealing assembly includes a first drive motor, a sealing block is fixedly connected to the output shaft of the first drive motor, and a temperature sensor is provided on the air inlet pipe.

[0007] In the above-mentioned cooling device for a bag filter, a mixing chamber is fixedly connected inside the dust collector body, a cold air fan is fixedly connected to the outer wall of the dust collector body, a cold air duct is provided on the cold air fan, the cold air duct and the air inlet pipe extend into the mixing chamber, and an outlet is provided on the mixing chamber.

[0008] In the aforementioned bag filter cooling device, a second drive motor is fixedly connected to the inner wall of the upper end of the mixing box, and a fan blade is fixedly connected to the output shaft of the second drive motor.

[0009] In the above-mentioned bag filter cooling device, a filter screen is provided inside the air supply pipe, a collection box is fixedly connected to the base, the upper end of the collection box is sealed to the lower end of the air supply pipe, a chip discharge hole is opened inside the air supply pipe, the air supply pipe is connected to the collection box through the chip discharge hole, and a drawer is slidably connected to the collection box.

[0013] The multi-segment U-shaped conveying channel allows for a longer cooling time in the cooling box, resulting in better cooling effect. The fan blades mix the cold air from the air cooler with the dust-laden gas, lowering the gas temperature. The filter screen filters and intercepts large dust particles carried in the dust-laden gas, which are then collected in the collection box, reducing damage to the bag filter and extending the service life of the filter bags.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 3 As shown,

[0021] A cooling device for a bag filter dust collector includes a base 2 and a dust collector body 3. The dust collector body 3 is fixedly connected to the base 2. An air inlet pipe 4 is provided at the lower end of the dust collector, and an air outlet pipe 5 is provided at the upper end of the dust collector body 3. A mounting plate 6 is fixedly connected inside the dust collector body 3, and a plurality of dust filter bags 7 are provided on the mounting plate 6. The device is characterized in that a cooling box 8 is fixedly connected to the base 2, and a conveying channel 9 is provided inside the cooling box 8. An air supply pipe 10 is fixedly connected to one side of the cooling box 8. The air supply pipe 10 is connected to one end of the conveying channel 9, and the other end of the conveying channel 9 passes through the side wall of the cooling box 8 and is connected to one end of the air inlet pipe 4. A sealing component is provided on the dust collector body 3 to seal the other end of the air inlet pipe 4.

[0022] In this embodiment, the dust-laden gas enters the conveying channel 9 through the air supply pipe 10. The dust-laden gas in the conveying channel 9 is cooled in the cooling box 8 and then enters the air inlet pipe 4. When the dust-laden gas cools down to a certain temperature, the sealing component opens and the dust-laden gas is put into the dust collector body 3 for dust removal. If the temperature of the dust-laden gas is still too high, the sealing component closes until the dust-laden gas cools down to a suitable temperature.

[0023] In this embodiment, the sealing assembly includes a first drive motor 11, with a sealing block 12 fixedly connected to the output shaft of the first drive motor 11. A temperature sensor 13 is provided on the air intake pipe 4. The temperature sensor 13 detects the temperature of the dust-laden gas in the air intake pipe 4. If the temperature is lower than a preset temperature, the first drive motor 11 drives the sealing block 12 to rotate, opening the air intake pipe 4 and allowing the dust-laden gas to enter the dust collector body 3. If the temperature is higher than the preset temperature, the sealing block 12 blocks the air intake pipe 4, preventing it from entering the dust collector body 3.

[0024] In this embodiment, a mixing chamber 14 is fixedly connected inside the dust collector body 3, and a cooler 15 is fixedly connected to the outer wall of the dust collector body 3. The cooler 15 is equipped with a cooler duct 16, which, along with the air inlet pipe 4, extends into the mixing chamber 14. The mixing chamber 14 has an outlet 17. After initial cooling, the dust-laden gas reaches the mixing chamber 14 through the air inlet pipe 4. Then, the cooler 15 is activated, sending cool air into the mixing chamber 14 to mix with the dust-laden gas, thereby lowering the temperature of the gas. Finally, the gas is discharged from the outlet 17.

[0025] In this embodiment, a second drive motor 18 is fixedly connected to the inner wall of the upper end of the mixing box 14, and a fan blade 19 is fixedly connected to the output shaft of the second drive motor 18. The second drive motor 18 drives the fan blade 19 to rotate, which accelerates the mixing of cold air and dust-laden gas, and also has a cooling effect.

[0026] In this embodiment, a filter screen 20 is provided inside the air supply pipe 10, and a collection box 21 is fixedly connected to the base 2. The upper end of the collection box 21 is sealed to the lower end of the air supply pipe 10. A chip removal hole 22 is provided inside the air supply pipe 10, and the air supply pipe 10 is connected to the collection box 21 through the chip removal hole 22. A drawer 23 is slidably connected to the collection box 21. Large dust particles carried in the high-temperature dusty gas are intercepted when passing through the filter screen 20. The intercepted large dust particles fall into the collection box 21 through the chip removal hole 22. When there is a lot of dust in the collection box 21, the drawer 23 can be pulled out to empty it.

[0027] In this embodiment, a push rod motor 24 is fixedly connected inside the dust collector body 3. A movable frame 25 is fixedly connected to the push rod of the push rod motor 24. Several annular water tanks 26 corresponding to the dust collector filter bags 7 are fixedly connected to the movable frame 25. The push rod motor 24 drives the movable frame 25 and the annular water tanks 26 to move up and down. The annular water tanks 26 come into contact with the outer surface of the dust collector filter bags 7 to exchange heat and reduce the surface temperature of the dust collector filter bags 7.

[0028] In this embodiment, the conveying channel 9 is composed of multiple U-shaped tubes connected end to end. The multi-segment U-shaped tubes in the conveying channel 9 allow for a longer cooling time for the dust-laden gas within the cooling box 8, resulting in a better cooling effect.
