Description

Technical Field

[0001] This invention relates to the field of dust removal technology in the production of paste-like protective products, and more specifically, to a wet cyclone dust removal method and apparatus for the raw material feeding port of paste-like protective products. Background Technology

[0002] This dust collection device for the feeding port of ointment-type skincare raw materials is adapted to the feeding process of powder raw materials in ointment-type skincare products. It employs a stainless steel sealed feeding chamber combined with negative pressure ventilation, cosmetic-grade membrane filter cartridges, and a pulse automatic dust removal structure. During feeding, a stable negative pressure is formed inside the chamber to adsorb fine dust raised during bag opening and unloading. After the filter cartridge traps the powder, clean air is discharged. Dust that falls during backflushing is recycled back into the hopper for reuse. Simultaneously, an inner wall anti-stick scraping component prevents ointment powder from adhering and clogging, effectively preventing dust overflow and contamination of the workshop and ointment raw materials. It meets the GMP cleanroom standards for cosmetic production, addressing the needs of dust control, raw material recovery, and easy equipment cleaning.

[0003] The prior art publication CN110694413A discloses a wet cyclone dust collector. By setting the separation net with a V-shaped multi-fold structure around the hub, the area of ​​the separation net can be increased. This ensures dust collection efficiency while reducing ventilation resistance, thus achieving high efficiency and low energy consumption, thereby improving the overall dust collection efficiency of the device. Furthermore, it has advantages such as small size, simple structure, high dust collection efficiency, low ventilation resistance, high allowable airflow velocity without clogging, low operating cost, significant energy saving effect, and no need for frequent maintenance.

[0004] When this technology is in use, it collects dust-laden water droplets into a water tank for dust removal. However, when the dust-laden water droplets enter the water tank, the water in the tank will have a high content of impurities. Since the existing technology is not convenient for filtering the water after dust removal, when it is extracted and sprayed out through the atomizing device, it is easy to cause the atomizing nozzle to become clogged and the atomization effect to deteriorate. At the same time, after the water is circulated, the dust will repeatedly flow back into the dust removal chamber with the water mist, which will reduce the overall dust collection effect.

[0005] Therefore, we have made improvements to this by proposing a wet cyclone dust removal method and device for the feeding port of paste-like protective materials. Summary of the Invention

The top end of the rotating shaft is fixedly connected to a drive wheel, and the drive wheel and the driven wheel are meshed and driven. One end of the rotating shaft located in the liquid collection tank is fixedly connected to a transmission sleeve. The outer wall of the transmission sleeve is provided with a wave-shaped groove. The end of the rotating shaft near the motor is fixedly connected to a transmission wheel.

[0012] Preferably, the secondary vortex assembly includes a sliding frame, with a guide rod fixedly connected to the bottom end of the sliding frame. The bottom end of the guide rod extends through the inner wall of the liquid collection tank to the inner wall of the dust collector and is slidably engaged with the inner wall of the corrugated annular groove. Multiple extrusion plugs are fixedly connected to the outer periphery of the sliding frame in a ring structure. An open cylinder is slidably engaged with the outer wall of the bottom end of each extrusion plug. The open cylinder is fixedly connected through the inner wall of the liquid collection tank. A spray pipe is fixedly connected through the bottom end of the open cylinder, and the other end of the spray pipe extends into the liquid collection tank.

[0013] Preferably, the transmission assembly includes a gear disc, which is rotatably connected to the inner wall of the dust collector via a pin.

A gear two is fixedly connected to the top end of the connecting shaft.

[0014] Preferably, the filter assembly includes a cylindrical frame, with limiting rings fixedly connected to both the upper and lower ends of the cylindrical frame. The outer wall of the limiting ring is rotatably connected to the inner wall of the annular groove. Multiple filter plates are inserted into the cylindrical frame in an annular structure around its perimeter.

[0015] Preferably, both the upper and lower ends of the cylindrical frame are slidably fitted with retaining rings, and one side of each retaining ring is fixedly connected to the cylindrical frame with multiple springs.

[0016] Preferably, the water spray ring pipe is fixedly connected to the inner wall of the humidification chamber, and the outer wall of the water spray ring pipe has a ring structure with multiple nozzles fixedly connected thereto. One end of the water spray ring pipe extends through the inner wall of the humidification chamber to the outside.

[0017] A wet cyclone dust removal method for feeding inlets of paste-like protective product raw materials specifically includes the following steps:

[0018] S1. When the equipment is running, align the dust collection ring with the feeding port of the paste-like protective material. The powder and dust generated during the feeding process are collected by the dust collection ring and introduced into the humidification chamber at the top of the dust collection tank through the air guide pipe. At the same time, the external circulating water source is connected to the water spray ring pipe, and fine water mist is sprayed through multiple nozzles arranged in a ring to spray and humidify the dust-laden airflow in all directions. This allows the suspended fine powder and dust to fully combine with the water mist to form dust-laden droplets, completing the dust humidification and capture, and preventing the fine dust from escaping. At the same time, the motor drives the rotating shaft to rotate, and through the engagement of the top active wheel with the driven wheel, it drives the fan blades inside the air guide pipe to rotate, which helps to guide the dust-laden airflow into the tank quickly and improves the intake dust removal efficiency.

[0019] S2. Then, the humidified dust-laden water droplets are evenly introduced into the cyclone dust removal chamber through multiple sets of guide tubes. The rotating shaft drives the cyclone impeller to rotate at high speed, forming a high-speed forced cyclone field inside the cyclone dust removal chamber. Under the action of centrifugal force, the dust-laden water droplets are thrown at high speed towards the inner wall of the chamber and the outer filter components. The dust-laden water flows to the filter components, completing the first-stage cyclone dust removal operation.

[0020] S3. During the rotation of the rotating shaft, the bottom transmission wheel is driven to rotate. Through the multi-stage meshing transmission of the gear plate, gear one, connecting shaft, and gear two, the ring rack is driven to rotate the entire filter assembly at a uniform speed. The cylindrical frame drives multiple sets of filter plates to rotate in a ring, receiving the swirling dust-laden water flow in all directions, without any local dust accumulation dead corners, effectively avoiding filter pore blockage. After the dust-laden water flow passes through the filter plates, the powder impurities are intercepted, and the clean water flows downward into the collection tank, achieving preliminary water purification. At the same time, the spring presses against the retaining ring to keep the filter plate assembly stable.

[0021] S4. After the initial filtration, some water still contains fine powder impurities that remain in the collection tank. When the rotating shaft rotates, it drives the transmission sleeve to rotate synchronously. Through the outer wall wave ring groove, it drives the guide rod and sliding frame to move up and down reciprocally. The sliding frame drives multiple sets of extrusion plugs to reciprocate inside the open cylinder, generating negative pressure and high-pressure jet force. The dust-containing wastewater inside the collection tank is sprayed upward through the spray pipe back to the cyclone dust removal chamber, where it is separated again by high-speed cyclone separation and secondary filtration by the filter plate. This thoroughly intercepts fine dust impurities, greatly improving the water purification accuracy and dust removal effect.

[0022] S5. After passing through multiple stages of swirl and filtration, the clean water can be returned to the spray ring pipe, realizing the closed-loop recycling of water resources for spraying. This eliminates the need for frequent water replacement, reducing water waste and wastewater discharge.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. By setting up a cyclone dust removal component, the water spray ring pipe first sprays and humidifies the dust-laden air. The mixed dust-laden water flows through the cyclone dust removal component to form a high-speed cyclone. Relying on centrifugal force, the dust-laden water is thrown to the filter component to complete online purification. It can separate dust impurities in the water in real time, avoid impurities from accumulating and clogging the nozzles, and avoid dust from flowing back with the circulating water mist, thus reducing dust removal efficiency. There is no need to frequently change the water in the water tank, reducing water waste. The overall structure is compact, and dust removal and purification are completed simultaneously. It is suitable for the feeding of cream-type skin care powder, realizing a dust removal method of efficient wet dust removal and water self-filtration.

[0025] 2. By setting up a secondary cyclone assembly, after the dust-laden water impacts the filter assembly, part of the water is filtered through the filter assembly, while the other part of the water carries impurities to the collection tank below. At this time, the cyclone dust collector assembly will drive the squeeze plug to move up and down reciprocally through the wave ring groove on the transmission sleeve. At the same time, in conjunction with the open cylinder in the collection tank, the dust-laden water in the collection tank is sprayed back up to contact the cyclone dust collector assembly for filtration again, further improving the dust removal and filtration efficiency.

[0026] 3. By setting up a transmission component, the filter component can be driven to rotate while the cyclone dust collector component is rotating. The rotating filter component can receive the dust-laden water flow in all directions, avoiding the accumulation and clogging of impurities on the filter surface, which greatly improves the water filtration rate and purification effect. The fully purified water can be circulated to the spray ring pipe for continuous spraying, realizing the closed-loop reuse of water resources, reducing wastewater discharge and water replacement frequency, and ensuring the wet dust removal effect under the condition of feeding cream skin care powder, thereby reducing water costs.

[0054] In the preferred embodiment of this technical solution, please refer to Figure 3 As shown, the water spray ring pipe 7 is fixedly connected to the inner wall of the humidification chamber 101. The outer wall of the water spray ring pipe 7 has a ring structure with multiple nozzles 701 fixedly connected to it. One end of the water spray ring pipe 7 extends through the inner wall of the humidification chamber 101 to the outside.

[0055] Furthermore, the water spray ring pipe 7 is a ring-shaped spray water supply structure, connected to an external circulating water supply device, which can introduce the purified circulating water into the pipe; multiple sets of evenly arranged ring-shaped nozzles 701 can achieve full coverage spraying, forming a uniform and fine water mist inside the humidification chamber 101, so that the incoming dust-laden airflow is fully mixed with the water mist, quickly adsorbing fine skin dust, completing the airflow humidification and dust removal. The ring-shaped spray structure sprays evenly, has a good humidification effect, and has no dead corners for dust removal.

[0056] A wet cyclone dust removal method for feeding inlets of paste-like protective product raw materials specifically includes the following steps:

[0057] S1. When the equipment is running, the dust collection ring hood 202 is aligned with the feeding port of the paste-like protective material. The powder dust generated during the feeding process is collected by the dust collection ring hood 202 and introduced into the humidification chamber 101 at the top of the dust collection tank 1 through the air guide pipe 201. At the same time, the external circulating water source is connected to the water spray ring pipe 7, and fine water mist is sprayed through multiple nozzles 701 arranged in a ring to spray and humidify the dust-laden airflow in all directions, so that the suspended fine powder dust and water mist are fully combined to form dust-laden droplets, completing the dust humidification and capture, and preventing fine dust from escaping. At the same time, the motor 303 drives the rotating shaft 301 to rotate, and through the top active wheel 305 meshing with the driven wheel 204, it drives the fan blades 203 inside the air guide pipe 201 to rotate, which helps to guide the dust-laden airflow to quickly enter the tank and improve the intake dust removal efficiency.

[0058] S2. Then, the humidified dust-laden water droplets are evenly introduced into the cyclone dust removal chamber 102 through multiple sets of guide pipes 103. The rotating shaft 301 drives the cyclone impeller 302 to rotate at high speed, forming a high-speed forced cyclone field inside the cyclone dust removal chamber 102. Under the action of centrifugal force, the dust-laden water droplets are thrown at high speed towards the inner wall of the chamber and the outer filter assembly 6. The dust-laden water flows to the filter assembly 6, completing the first-stage cyclone dust removal operation.

[0059] S3. During the rotation of the rotating shaft 301, the bottom transmission wheel 308 is driven to rotate. Through the multi-stage meshing transmission of the gear disc 501, gear one 502, connecting shaft 503, and gear two 504, the ring rack 604 is driven to rotate the entire filter assembly 6 at a uniform speed. The cylindrical frame 601 drives multiple sets of filter plates 603 to rotate in a ring, receiving the swirling dust-laden water flow in all directions, without any local dust accumulation dead corners, effectively avoiding filter pore blockage. After the dust-laden water flow is filtered by the filter plates 603, the powder impurities are intercepted, and the clean water flows downward into the collection tank 104, achieving preliminary purification of the water. At the same time, the spring 606 presses against the retaining ring 605 to keep the filter plate 603 assembly stable.

[0060] S4. After the initial filtration, some water still contains fine powder impurities, which remain in the collection tank 104. When the rotating shaft 301 rotates, it drives the transmission sleeve 306 to rotate synchronously. Through the outer wall wave ring groove 307, it drives the guide rod 402 and the sliding frame 401 to move up and down reciprocally. The sliding frame 401 drives multiple sets of extrusion plugs 403 to reciprocate inside the open cylinder 404, generating negative pressure and high-pressure jet force. The dust-containing wastewater inside the collection tank 104 is sprayed upwards through the spray pipe 405 and returned to the cyclone dust removal chamber 102. It is then separated by high-speed cyclone separation and filtered twice by the filter plate 603, which completely intercepts fine dust impurities and greatly improves the water purification accuracy and dust removal effect.

[0061] S5. After passing through multiple stages of swirl and filtration, the clean water can be returned to the spray ring pipe 7, realizing the closed-loop recycling of water resources for spraying and utilization. This eliminates the need for frequent water replacement, reducing water waste and wastewater discharge.

10. A method for wet cyclone dust removal at the feeding port of a paste-like protective material, comprising the wet cyclone dust removal device for the feeding port of a paste-like protective material as described in any one of claims 1-9, specifically including the following steps: S1. When the equipment is running, the dust collection ring (202) is aligned with the feeding port of the paste-like protective material. The powder dust generated during the feeding process is collected by the dust collection ring (202) and introduced into the humidification chamber (101) at the top of the dust collector (1) through the air guide pipe (201). At the same time, the external circulating water source is connected to the water spray ring pipe (7), and the fine water mist is sprayed through multiple nozzles (701) arranged in a ring to spray and humidify the dust-laden airflow in all directions, so that the suspended fine powder dust and water mist are fully combined to form dust-laden droplets, completing the dust humidification and collection, and preventing the fine dust from escaping. At the same time, the motor (303) drives the rotating shaft (301) to rotate, and the driven wheel (204) meshes with the top active wheel (305), driving the fan blades (203) inside the air guide pipe (201) to rotate, assisting in guiding the dust-laden airflow to quickly enter the tank and improving the intake dust removal efficiency. S2. Then, the humidified dust-laden water droplets are evenly introduced into the cyclone dust removal chamber (102) through multiple sets of guide pipes (103). The rotating shaft (301) drives the cyclone impeller (302) to rotate at high speed, forming a high-speed forced cyclone field inside the cyclone dust removal chamber (102). Under the action of centrifugal force, the dust-laden water droplets are thrown at high speed towards the inner wall of the chamber and the outer filter assembly (6). The dust-laden water flows to the filter assembly (6) to complete the first-stage cyclone dust removal operation. S3. During the rotation of the rotating shaft (301), the bottom transmission wheel (308) is driven to rotate. Through the multi-stage meshing transmission of the gear disc (501), gear one (502), connecting shaft (503), and gear two (504), the ring rack (604) is driven to drive the entire filter assembly (6) to rotate at a constant speed. The cylindrical frame (601) drives multiple sets of filter plates (603) to rotate in a ring, receiving the swirling dust-laden water flow in all directions, without any local dust accumulation dead corners, effectively avoiding filter hole blockage. After the dust-laden water flow is filtered by the filter plate (603), the powder impurities are intercepted, and the clean water flows downward into the collection tank (104) to achieve preliminary purification of the water. At the same time, the spring (606) presses against the retaining ring (605) to keep the filter plate (603) assembled stably. S4. Then, after the initial filtration, some water still has fine powder impurities remaining in the collection tank (104). When the rotating shaft (301) rotates, it drives the transmission sleeve (306) to rotate synchronously. Through the outer wall wave ring groove (307), it drives the guide rod (402) and the sliding frame (401) to move up and down. The sliding frame (401) drives multiple sets of extrusion plugs (403) to reciprocate inside the open cylinder (404), generating negative pressure and high-pressure jet force. The dust-containing sewage inside the collection tank (104) is sprayed upward through the jet pipe (405) back to the cyclone dust removal chamber (102), where it is separated by high-speed cyclone separation and filtered twice by the filter plate (603) to completely intercept fine dust impurities and greatly improve the water purification accuracy and dust removal effect. S5. After multiple stages of swirling and filtration, the clean water can be returned to the spray ring pipe (7) to realize the closed-loop recycling of water resources for spraying, without the need for frequent water replacement, thus reducing water waste and wastewater discharge.
