Description

Technical Field

[0001] This utility model relates to the field of dust treatment technology, specifically to a dust collection and treatment device for ceramic production. Background Technology

[0002] With the rapid development of industry, the scale of ceramic production has continued to expand. The dust generated has caused serious pollution to the atmospheric environment. Dust emitted into the air will lead to a decline in air quality, affect the living environment of surrounding residents, and may also pollute soil, water sources, and disrupt the ecological balance.

[0003] The applicant discovered through a search that a Chinese patent discloses "A dust collection device in the production of ceramsite", with publication number "CN117680463A". This patent mainly includes: a collection box, a dust collection component movably connected to the top of the collection box for drawing dust from the outside of the collection box into the collection box, and a swing component disposed on the top of the collection box and movably connected to the dust collection component for driving the dust collection component to swing at multiple angles on the top of the collection box. This device, by providing a dust collection component on the top of the collection box, and the dust collection component including but not limited to at least two sets of dust collection pipes composed of connecting pipes, exhaust devices, and dust collection hoods, with the two sets of dust collection pipes arranged opposite each other, can absorb dust from different positions on the outside of the collection box, thereby increasing its working range and improving the applicability of this device in practical scenarios.

[0004] However, the following shortcomings still exist:

[0005] Because the dust has high humidity and strong stickiness, when the dust-laden gas flows through the inlet pipe, condensation will occur on the inner wall of the inlet pipe, causing the dust to stick to the inner wall of the inlet pipe. Therefore, the dust will clump and accumulate on the inner wall of the inlet pipe, causing blockage. To address this, we propose a dust collection and treatment device for ceramic production. Utility Model Content

[0006] The purpose of this invention is to provide a dust collection and treatment device for ceramic production.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust collection and treatment device for ceramic production, comprising a collection box, an induced draft fan installed on the top surface of the collection box, a demister fixed above the induced draft fan, and a cleaning assembly mounted above the demister. The cleaning assembly includes an air inlet pipe, a positioning ring, a positioning rod, a motor, a rotating shaft, a collar, a vortex plate, a cleaning brush, a guide groove, a water collection tank, a drain pipe, and a control valve. The air inlet pipe is connected to the top surface of the demister, and the positioning ring and the positioning rod are both located at both ends of the inner wall of the air inlet pipe. The positioning rod is ring-shaped. The swirl plates are arranged in a circular array on the outer diameter of the positioning ring. The motor is fixed to the top surface of the positioning ring. The rotating shaft is connected to the drive end of the motor. The collar is sleeved on the outside of the rotating shaft. There are five sets of collars. The collars are circular in shape. The swirl plates are arranged in a circular array on the outer diameter of the collars. The cleaning brush is fixed below the swirl plates and contacts the inner wall of the air inlet pipe. The guide groove is opened below the cleaning brush. The water collection tank is installed on both sides of the inner wall of the demister. The drain pipe is connected to one side of the water collection tank. The control valve is installed above the drain pipe.

[0008] As a further embodiment of this utility model: the demister is internally provided with plates, the plates being in the shape of corrugated blades, and a plurality of such plates are provided. A demisting screen is installed below the plates, and a collecting hopper is fixed below the demisting screen. Exhaust holes are provided on both sides of the collecting hopper, and a plurality of such exhaust holes are provided. Guide plates are provided on both sides below the collecting hopper, and the guide plates are inclined in a shape that is higher at the top and lower at the bottom. The collecting hopper is connected to a water collection tank through the guide plates, and a through hole is provided at the connection between the guide plates and the water collection tank.

[0009] As a further embodiment of this utility model, an air inlet is connected to the lower part of the induced draft fan.

[0013] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0014] 1. This utility model uses a swirl plate to drive the cleaning brush to rotate. The cleaning brush contacts the inner wall of the air inlet pipe and wipes and cleans the pipe wall during rotation, removing dust, dirt and droplets, preventing pipe blockage and ensuring gas flow.

[0015] 2. This utility model uses a motor to drive the rotating shaft to rotate, and the collar rotates synchronously, which drives the swirl plates arranged in a ring array on its outer diameter to rotate. The swirl plates cause the gas entering the intake pipe to form a rotating airflow.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0025] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please see the appendix Figure 1 -Appendix Figure 5 This utility model relates to a dust collection and treatment device for ceramic production, comprising a collection box 1, an induced draft fan 2 installed on the top surface of the collection box 1, and a demister 3 fixed above the induced draft fan 2. Under the premise that... Figure 2 , Figure 4 and Figure 5As shown, a cleaning assembly 4 is mounted above the demister 3. The cleaning assembly 4 includes an air inlet pipe 401, a positioning ring 402, a positioning rod 403, a motor 404, a rotating shaft 405, a collar 406, a swirl plate 407, a cleaning brush 408, a guide channel 409, a water collection tank 410, a drain pipe 411, and a control valve 412. The air inlet pipe 401 is connected to the top surface of the demister 3. The positioning ring 402 and the positioning rod 403 are located at both ends of the inner wall of the air inlet pipe 401. The positioning rods 403 are arranged in a ring array on the outer diameter of the positioning ring 402. The motor 404 is fixed to the top surface of the positioning ring 402. The rotating shaft 405 is connected to the drive end of the motor 404. A collar 406 is fitted onto the outside of the rotating shaft 405. Five sets of collars 406 are provided. The collars 406 are circular in shape. Swirl plates 407 are arranged in a ring array on the outer diameter of the collars 406. A cleaning brush 408 is fixed below the swirl plates 407 and contacts the inner wall of the air inlet pipe 401. A guide groove 409 is opened below the cleaning brush 408. A water collection tank 410 is installed on both sides of the inner wall of the demister 3. A drain pipe 411 is connected to one side of the water collection tank 410. A control valve 412 is installed above the drain pipe 411. Under the strong power of the induced draft fan 2, a large amount of dust-laden gas is rapidly introduced into the air inlet pipe 401. At the same time... Motor 404 drives shaft 405 to rotate. Since collar 406 is fitted around the outside of shaft 405 and rotates synchronously with it, it drives the swirl plates 407, arranged in a ring array on the outer diameter of collar 406, to rotate. The rotation of the swirl plates 407 generates rotational force on the gas entering intake pipe 401, creating a rotating airflow. Under the action of this rotating airflow, water droplets in the gas are thrown against the wall of intake pipe 401 by centrifugal force, and the droplets flow downwards along the wall. This enhances the gas-liquid separation effect and effectively removes more mist from the gas. Simultaneously, the rotation of the swirl plates 407 drives... The cleaning brush 408, which is connected to it, rotates together. Through the contact between the cleaning brush 408 and the inner wall of the air intake pipe 401, the inner wall of the air intake pipe 401 is wiped and cleaned during the rotation, thereby removing dust, dirt and condensed droplets attached to the pipe wall, preventing pipe blockage and ensuring smooth air flow. Since the guide channel 409 is located below the cleaning brush 408, it guides the mist droplets, dust and dirt swept down by the cleaning brush 408 to the water collection tank 410 for centralized collection and treatment. When the sewage in the water collection tank 410 accumulates to a certain level, the operator turns the control valve 412, and the sewage in the water collection tank 410 will be discharged.

[0027] In Example 1, the demister 3 is provided with a plate 5 inside. The plate 5 is in the shape of a wave blade. There are several plates 5. A demisting net 6 is installed below the plate 5. A collecting hopper 7 is fixed below the demisting net 6. There are exhaust holes 8 on both sides of the collecting hopper 7. There are several exhaust holes 8. Guide plates 9 are provided on both sides below the collecting hopper 7. The guide plates 9 are inclined in shape with the top higher than the bottom. The collecting hopper 7 is connected to the water collection tank 410 through the guide plates 9. A through hole 10 is provided at the connection between the guide plates 9 and the water collection tank 410.

[0028] Specifically, when the mist-laden gas enters the plate 5 area through the inlet pipe 401, the mist droplets collide with the surface of the plate 5 due to the downward inertia of the flow. Under the adsorption effect of the plate 5 surface, the mist droplets adhere to it and then gather into larger droplets. At this time, the gas passes through the gap between the plates 5 and enters the demisting net 6. The demisting net 6 intercepts the fine mist droplets that may leak through the gap between the plates 5, thereby achieving gas-liquid separation and greatly reducing the amount of mist droplets carried in the gas. After the dual filtration of the plates 5 and the demisting net 6, the separated mist droplets converge into water flow, which falls naturally downward under the pull of gravity and flows into the collecting hopper 7. At this time, the water flow into the collecting hopper 7 flows into the water collection tank 410 along the guide plates 9 on both sides, which are inclined from top to bottom. If the water droplets fall on the guide plates 9, the water droplets flow towards the through holes 10 along their inclined slope and enter the water collection tank 410 through the through holes 10.

[0029] In embodiment 2, a water tank 12 is installed on one side of the collection box 1, and a water pump 13 is installed on the top surface of the water tank 12. A main flow pipe 14 is connected above the water pump 13. A first water inlet pipe 15 is connected to one side of the middle of the main flow pipe 14. The first water inlet pipe 15 is connected to the first nozzle 16 through the collection box 1. A second water inlet pipe 17 is connected to one side above the main flow pipe 14. The second water inlet pipe 17 is connected to the second nozzle 18 through the air inlet pipe 401. Water valves are installed on both the second water inlet pipe 17 and the first water inlet pipe 15.

[0030] Specifically, when it is necessary to spray and suppress dust in the airflow entering the collection box 1, the water valve above the first water inlet pipe 15 is opened. At the same time, the water pump 13 draws clean water stored in the water tank 12 and delivers it to the main flow pipe 14. The water flows into the first water inlet pipe 15 along the main flow pipe 14, and is sprayed out in an atomized state by the first nozzle 16, capturing dust particles in the airflow and effectively purifying the gas entering the collection box 1. When it is necessary to clean the internal components of the demister 3, the water valve above the first water inlet pipe 15 is closed and the water valve above the second water inlet pipe 17 is opened. At this time, the water pump 13 continuously inputs clean water from the water tank 12 into the main flow pipe 14. The water flows into the second water inlet pipe 17 along a predetermined route and is sprayed out through the second nozzle 18, thereby washing the plates 5 and the demister screen 6 inside the demister 3. Under the impact of the water mist, the dust attached to them is swept away, ensuring that all components of the demister 3 are always in a state of high-efficiency operation.

[0031] Working principle:

[0032] First, after the induced draft fan 2 starts, a large amount of dust-laden gas is drawn into the intake pipe 401. At the same time, the motor 404 drives the rotating shaft 405 to rotate, and the collar 406 rotates synchronously, driving the cyclone plate 407 of the ring array to rotate, so that the gas in the intake pipe 401 forms a rotating flow. Under the action of centrifugal force, the water droplets in the gas are thrown against the pipe wall and flow down, improving the gas-liquid separation effect and further filtering out the mist droplets. When the cyclone plate 407 rotates, it drives the cleaning brush 408 to clean the inner wall of the intake pipe 401, wiping away dust, dirt and condensed droplets. The cleaned impurities are collected into the water collection tank 410 through the guide channel 409. When the sewage accumulates to a certain level, the staff can drain the water by turning the control valve 412. The introduced airflow is purified by the intake pipe 401 and the demister 3, and then smoothly enters the collection box 1 through the air inlet 11.

[0033] The mist-laden gas enters the area where the plate 5 is located through the inlet pipe 401. The mist droplets collide with the plate 5 due to the downward inertia. Due to the adsorption properties of the plate 5, they adhere to it and then agglomerate into large droplets. The gas passes through the gaps between the plates 5 and enters the demisting net 6. The demisting net 6 intercepts the fine mist droplets that leak through the gaps between the plates 5, effectively separating the gas and liquid. After being filtered by the plates 5 and the demisting net 6, the separated mist droplets converge into a water flow and fall directly into the collecting hopper 7 under the action of gravity. The inclined guide plates 9 on both sides of the collecting hopper 7 guide the water flow into the water collection tank 410. When the water droplets fall into the guide plates 9, the water droplets flow into the water collection tank 410 along the inclination of the guide plates 9 and through the through holes 10.

[0034] When it is necessary to spray the dust airflow entering the collection box 1 to reduce dust, the water valve of the first water inlet pipe 15 is opened, and the water pump 13 quickly draws water from the water tank 12, through the main pipe 14 and the first water inlet pipe 15, and sprays it out by the first nozzle 16 to capture dust and purify the air intake. The dust after spraying is subjected to gravity and flows into the mud collection box 22 through the mud discharge port 21. The gas is discharged through the exhaust pipe 19. When the gas enters the exhaust pipe 19, it will pass through the gas purifier 20, which will further purify it.

[0035] If it is necessary to clean the internal components of the demister 3, first close the water valve of the first water inlet pipe 15, open the water valve of the second water inlet pipe 17, and the water pump 13 continues to pump water, which is then sprayed out through the main water pipe 14 and the second water inlet pipe 17 and sprayed out through the second nozzle 18 to wash the plates 5 and the demister screen 6 of the demister 3, remove the attached dust, and ensure its efficient operation. At this point, the entire working process is completed.
