Description

Technical Field

[0001] This application relates to the field of solid waste treatment technology, and in particular to a dust suppression device for the production of carbon fiber composite materials. Background Technology

[0002] Carbon fiber composites are renowned for their lightweight, high strength, and fatigue resistance, and are widely used in aerospace, wind power, rail transportation, and automotive lightweighting. The production process of carbon fiber composites, especially automated production lines, requires a high degree of cleanliness, as dust directly affects the appearance and mechanical properties of the final molded parts. During automated production of carbon fiber composites, processes such as material shearing and hot pressing generate dust. This type of dust is classified as solid waste pollution, which not only harms the respiratory health of on-site workers but also reduces product quality. Therefore, the installation of dust suppression devices is essential.

[0003] In existing technologies, dust suppression devices used in carbon fiber composite material production mostly employ water mist for large-scale dust reduction, while simultaneously using fans to extract escaping dust, achieving synergistic operation of the two dust suppression methods. However, currently, these two methods are mostly simply assembled, failing to achieve full coverage dust suppression in a designated area; the water mist system and the negative pressure dust extraction fan are only simply assembled, resulting in limited dust suppression improvement. Furthermore, when the atomizing nozzle is too close to the dust extraction port, the water mist is easily sucked away by the fan, causing self-circulation loss of atomized water and further reducing the dust suppression coverage area. These problems urgently need to be solved. Summary of the Invention

[0004] This application proposes a dust suppression device for the production of carbon fiber composite materials, which has the advantage of good dust suppression effect and is used to solve the problems in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a dust suppression device for carbon fiber composite material production, comprising a housing, multiple sets of extension pipes installed on the outer periphery of the housing, a spray mechanism connected to the top of the housing, a clean water tank and a wastewater tank installed at the bottom of the inner cavity of the housing, a filter cylinder and a fixed cylinder fixedly installed on the top of the wastewater tank, filter holes opened on the outer surface of the filter cylinder, a fan connected to the top of the fixed cylinder, a support ring fixedly installed on the top of the fixed cylinder, a sealing ring sealed inside the support ring, a cleaning chamber fixedly connected to the bottom of the sealing ring, a water supply pipe and a water pump installed on the top of the clean water tank, and a three-way valve installed between the water pump, the support ring, and the spray mechanism; The spraying mechanism includes a connecting pipe connected to a three-way valve, a water storage tank is fixedly connected to the top of the connecting pipe, multiple sets of spray pipes are fixedly connected to the outer surface of the water storage tank, and multiple nozzles are fixedly connected to the bottom of the spray pipes. This device has been redesigned to significantly improve its dust suppression effect. To achieve this, it combines negative pressure suction and atomized dust suppression. Specifically, a fan and filter cartridge located inside the housing provide filtered negative pressure suction. During operation, the negative pressure suction area is achieved using four sets of support pipes, extension pipes, and flared nozzles on the outer periphery of the housing. The extension pipes can move along the axis of the support pipes, thereby changing the distance between the flared nozzles and the housing body. Atomized dust suppression is then achieved through a spray mechanism located at the top of the housing. Clean water from the clean water tank is pumped to the spray mechanism, and then atomized droplets are sprayed through the spray pipes and nozzles to form area atomization. This device distributes dust suppression and negative pressure suction vertically, using atomized water to cover the dust area from top to bottom. The extension pipes and flared nozzles extending outward along the outer periphery of the housing are used to prevent some dust from escaping through negative pressure suction, thus forming a complete dust suppression area, effectively preventing dust escape and significantly improving the dust suppression effect of the device.

[0006] Preferably, the cleaning chamber has a cleaning cavity facing the outer surface of the filter cartridge. A partition is fixedly connected inside the cleaning cavity. An opening is provided at the top of the partition. A water outlet pipe extending towards the filter cartridge along its thickness direction is fixedly connected to the side of the partition. The axis of the water outlet pipe is inclined.

[0007] Preferably, there are two cleaning chambers, which are equidistantly distributed around the outer surface of the filter cylinder. A connecting block is fixedly connected between the two cleaning chambers, and the connecting block and the inner side of the cleaning chamber are rotatably mounted on the outer surface of the fixed cylinder.

[0008] Preferably, a support tube is fixedly connected to the outer circumferential surface of the box body, the extension tube is sealed and sleeved on the outer surface of the support tube, one end of the extension tube is provided with a flared mouth, and the extension tube can move along the axis of the support tube.

[0009] Preferably, the filter cartridge is frustum-shaped, and the diameter of the top opening of the filter cartridge is smaller than the diameter of the bottom opening.

[0010] Preferably, the bottom end of the water inlet pipe passes through the top of the clean water tank and enters the bottom of the inner cavity of the clean water tank, and the two ends of the water pump are respectively connected to the three-way valve and the water inlet pipe.

[0011] Preferably, a water supply pipe is fixedly connected to the left side of the top of the clean water tank, and the top end of the water supply pipe extends to the left side of the tank body.

[0012] Preferably, the partition is arranged in a counterclockwise tilt within the cleaning chamber, and the cleaning chamber is divided into three chambers by the partition. The first chamber is directly connected to the sealing ring and is connected to the second chamber through a port. The second chamber is connected to the third chamber through a water outlet pipe.

[0013] The beneficial effects of this invention are as follows: 1. This device has been redesigned to significantly improve its dust suppression effect. To achieve this, the device combines negative pressure suction and atomized dust suppression. Specifically, a fan and filter cartridge located inside the chamber provide filtered negative pressure suction. During operation, the negative pressure suction area is achieved using four sets of support pipes, extension pipes, and flared nozzles on the outer periphery of the chamber. The extension pipes can move along the axis of the support pipes, thereby changing the distance between the flared nozzles and the chamber body. Atomized dust suppression is then achieved through a spray mechanism located at the top of the chamber. Clean water from the clean water tank is pumped to the spray mechanism, and then atomized droplets are sprayed through the spray pipes and nozzles to form area atomization. This device distributes dust suppression and negative pressure suction vertically, using atomized water to cover the dust area from top to bottom. The extension pipes and flared nozzles extending outward along the outer periphery of the chamber are used to prevent some dust from escaping through negative pressure suction, thus forming a complete dust suppression area, effectively preventing dust escape and significantly improving the dust suppression effect of the device.

[0014] 2. This device uses a filter cartridge to filter dust drawn into the inner cavity of the chamber. To achieve efficient automatic cleaning of the filter cartridge, a cleaning chamber is rotatably installed on the outside of the fixed cylinder and the filter cartridge to backwash the filter holes. A sealing ring is used to achieve a sealed rotatable connection between the cleaning chamber and the support ring. Clean water pumped by a water pump is introduced into the cleaning chamber through a three-way valve. When the clean water enters the three chambers of the cleaning chamber through the inlet and outlet pipe, it washes the outer surface of the filter cartridge and backwashes the filter holes. At the same time, the inclined design of the outlet pipe generates a reaction force on the entire cleaning chamber, which drives the cleaning chamber to rotate and completely covers the outer surface of the filter cartridge. Due to the sealed contact between the cleaning chamber and the filter cartridge, and the frustum shape of the filter cartridge, the clean water finally flows along the filter holes into the wastewater tank with only a small amount of leakage, thus improving the practicality of the device.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Please see Figures 1-8 This embodiment discloses a dust suppression device for carbon fiber composite material production, including a box 1. Multiple sets of extension pipes 6 are installed on the outer periphery of the box 1. A spray mechanism 3 is connected to the top of the box 1. A clean water tank 10 and a wastewater tank 11 are installed at the bottom of the inner cavity of the box 1. A filter cylinder 8 and a fixed cylinder 15 are fixedly installed on the top of the wastewater tank 11. The outer surface of the filter cylinder 8 is provided with filter holes 9. A fan 2 is connected to the top of the fixed cylinder 15. A support ring 17 is fixedly installed on the top of the fixed cylinder 15. A sealing ring 18 is sealed inside the support ring 17. A cleaning chamber 16 is fixedly connected to the bottom of the sealing ring 18. A water supply pipe 12 and a water pump 13 are installed on the top of the clean water tank 10. A three-way valve 14 is installed between the water pump 13, the support ring 17, and the spray mechanism 3. The spraying mechanism 3 includes a connecting pipe 31 that is connected to the three-way valve 14. A water storage tank 32 is fixedly connected to the top of the connecting pipe 31. Multiple sets of spray pipes 33 are fixedly connected to the outer surface of the water storage tank 32. Multiple nozzles 34 are fixedly connected to the bottom of the spray pipes 33. This device has been redesigned to significantly improve its dust suppression effect. To achieve this, the device combines negative pressure suction and atomized dust suppression. Specifically, a fan 2 and a filter cartridge 8 located inside the housing 1 provide filtered negative pressure suction. During operation, the negative pressure suction area is extended by four sets of support pipes 5, extension pipes 6, and a bell mouth 7 on the outer periphery of the housing 1. The extension pipes 6 can move along the axis of the support pipes 5, thereby changing the distance between the bell mouth 7 and the housing 1 body. Finally, a sprayer located at the top of the housing 1 further enhances the dust suppression effect. The device 3 performs atomization dust suppression. Water pump 13 pumps clean water from clean water tank 10 to spray mechanism 3, and then sprays atomized droplets through spray pipe 33 and nozzle 34 to form regional atomization. This device distributes dust suppression and negative pressure dust suction vertically during atomization. The atomized water covers the dust area from top to bottom. The extension pipe 6 and the flared mouth 7 extending outward along the outer periphery of the box 1 are used to prevent some dust from escaping through negative pressure dust suction, thus forming a complete dust suppression area, effectively preventing dust from escaping and significantly improving the dust suppression effect of the device.

[0020] In this embodiment, the cleaning chamber 16 has a cleaning cavity 19 facing the outer surface of the filter cylinder 8. A partition 20 is fixedly connected inside the cleaning cavity 19. A through-hole 21 is opened at the top of the partition 20. A water outlet pipe 22 extending towards the filter cylinder 8 along its thickness direction is fixedly connected to the side of the partition 20. The axis of the water outlet pipe 22 is inclined. like Figures 3-8 As shown, this device uses filter cartridge 8 to filter dust drawn into the inner cavity of the housing 1. To achieve efficient automatic cleaning of filter cartridge 8, the device uses a cleaning chamber 16 rotatably mounted on the outside of the fixed cylinder 15 and filter cartridge 8 to backwash the filter holes 9. A sealing ring 18 is used to achieve a sealed rotatable connection between the cleaning chamber 16 and the support ring 17. Clean water pumped by water pump 13 is introduced into the cleaning chamber 19 through a three-way valve 14. When the clean water enters the three chambers of the cleaning chamber 19 in sequence through the inlet 21 and the outlet pipe 22, the clean water washes the outer surface of the filter cartridge 8 and backwashes the filter holes 9. At the same time, the inclined setting of the outlet pipe 22 generates a reaction force on the cleaning chamber 16 as a whole, synchronously driving the cleaning chamber 16 to rotate and completely covering the outer surface of the filter cartridge 8. Since the cleaning chamber 16 and the filter cartridge 8 are sealed together, and with the frustum shape of the filter cartridge 8, the clean water finally flows along the filter holes 9 into the wastewater tank 11 with only a small amount of leakage, thereby improving the practicality of the device.

[0021] In this embodiment, there are two cleaning chambers 16, which are distributed equidistantly in a circle along the outer surface of the filter cylinder 8. A connecting block 23 is fixedly connected between the two cleaning chambers 16. The inner surfaces of the connecting block 23 and the cleaning chambers 16 are rotatably mounted on the outer surface of the fixed cylinder 15. like Figures 3-8 As shown, there are two cleaning chambers 16, which are equidistantly distributed around the outer surface of the filter cylinder 8, thereby improving the cleaning efficiency of the filter cylinder 8 and the filter holes 9. The two cleaning chambers 16 are connected by two connecting blocks 23 and are rotatably set on the outside of the filter cylinder 8 and the fixed cylinder 15.

[0022] In this embodiment, a support tube 5 is fixedly connected to the outer peripheral surface of the box 1, and an extension tube 6 is sealed and sleeved on the outer surface of the support tube 5. One end of the extension tube 6 is provided with a flared mouth 7, and the extension tube 6 can move along the axis of the support tube 5. like Figures 3-5 As shown, after the fan 2 is started, it will generate negative pressure, which will suck up dust from the outside through the support pipe 5, the extension pipe 6 and the horn 7. The support pipe 5 is used to support the extension pipe 6 and enable it to move along the axis of the support pipe 5, changing the distance between the horn 7 and the housing 1. This design allows the housing 1 to cover a larger area of ​​dust.

[0023] In this embodiment, the filter cylinder 8 is shaped like a frustum, and the diameter of the top opening of the filter cylinder 8 is smaller than the diameter of the bottom opening. like Figures 3-5 As shown, the frustum-shaped filter cylinder 8 is used to filter dust entering it. At the same time, when facing the backwash cleaning process of the cleaning chamber 16, the design of the filter cylinder 8, which is narrow at the top and wide at the bottom, allows the backwash wastewater to flow smoothly into the wastewater tank 11, instead of flowing back along the outer surface of the filter cylinder 8 to the outside of the clean water tank 10 and the wastewater tank 11. When the filter hole 9 is opened by clean water, its water flow efficiency will also increase, and there will be no water accumulation.

[0024] In this embodiment, the bottom end of the water inlet pipe 12 passes through the top of the clean water tank 10 and enters the bottom of the inner cavity of the clean water tank 10. The two ends of the water pump 13 are connected to the three-way valve 14 and the water inlet pipe 12 respectively. like Figure 3 , Figure 5 and Figure 7 As shown, the bottom end of the water inlet pipe 12 extends into the inner cavity of the clean water tank 10, and with the cooperation of the water pump 13, the clean water in the clean water tank 10 is pumped upward to the three-way valve 14. The three-way valve 14 can adjust the amount of clean water entering the spray mechanism 3 and the cleaning chamber 16, thereby realizing the atomization dust suppression of the spray mechanism 3 and the clean water rinsing function of the cleaning chamber 16.

[0025] In this embodiment, a water supply pipe 4 is fixedly connected to the left side of the top of the clean water tank 10, and the top end of the water supply pipe 4 extends to the left side of the tank body 1. like Figure 3 As shown, the water supply pipe 4 is connected to the top of the clean water tank 10, with its top end higher than the clean water tank 10, and is used to replenish the consumed clean water from the outside into the inner cavity of the clean water tank 10.

[0026] In this embodiment, the partition 20 is arranged in a counterclockwise rotation and tilted position in the inner cavity of the cleaning chamber 19. The cleaning chamber 19 is divided into three chambers by the partition 20. The first chamber is directly connected to the sealing ring 18 and is connected to the second chamber through the port 21. The second chamber is connected to the third chamber through the water outlet pipe 22. like Figures 4-6 As shown, when the clean water diverted from the three-way valve 14 enters the cleaning chamber 19 through the support ring 17 and the sealing ring 18, it will pass through chamber one, chamber two and chamber three in sequence. The inclined partition 20 and the water outlet pipe 22 will generate a reaction force when passing through the clean water, thereby pushing the cleaning chamber 16 to rotate.

[0027] Working principle: When this device is in operation, firstly, clean water is added to the clean water tank 10 through the water supply pipe 4. The movable extension pipe 6 can be moved and its position on the surface of the support pipe 5 can be changed. When the device performs dust suppression operation: Start the fan 2 and generate negative pressure in the inner cavity of the filter cartridge 8. The negative pressure acts outward through the inner cavity of the housing 1, the support pipe 5, the extension pipe 6 and the horn 7, and absorbs the dust on site. Under the action of negative pressure, the dust enters the filter cartridge 8 through the horn 7, the extension pipe 6 and the support pipe 5, is filtered and adheres to the outer surface of the filter cartridge 8. The filtered air is discharged to the outside environment through the filter hole 9 and the fan 2. Start water pump 13, and pump clean water from inside clean water tank 10 to three-way valve 14 through water inlet pipe 12. Control three-way valve 14 to ensure water can only flow upwards and enters spray mechanism 3. Figure 3 , Figures 7-8 As shown, water is diverted through the connecting pipe 31 and the water storage tank 32 to multiple sets of spray pipes 33, and finally sprayed outward through the nozzle 34. The atomized water is used to capture dust particles in the air to achieve the purpose of dust reduction. Since the distance between the nozzle 34 and the extension pipe 6 is far enough, the atomized water sprayed along the nozzle 34 will not be absorbed by the extension pipe 6. When it is necessary to clean the outer surface of the filter cartridge 8, turn off the fan 2 and control the three-way valve 14 to allow clean water pumped from the water pump 13 to flow downwards into the support ring 17. Figure 4 As shown, clean water passes through the sealing ring 18, enters the cleaning chamber 19, then through the opening 21 into chamber two, and finally sprays out through the outlet pipe 22. After entering chamber three, the clean water exerts positive pressure on the filter holes 9, flushing out the impurities clogging the filter holes 9, which then fall into the wastewater tank 11. Figure 6As shown, since the axis of the water outlet pipe 22 is inclined, when clean water is sprayed out along the water outlet pipe 22, a reaction force will be generated to push the baffle 20, the cleaning chamber 16, and the sealing ring 18 to rotate in the opposite direction, thereby covering the surface of the filter cartridge 8 and completing the automatic backwashing of the filter cartridge 8. At the same time, the spray mechanism 3 can still continue to operate.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
