Description

Technical Field

[0001] The present invention relates to air purification equipment, and particularly to a multiple air purification equipment for a dust workshop. Background Art

[0002] A large number of dust particles are diffused in a dust workshop. Workers are in such a working environment for a long time, and the dust particles enter and accumulate in the lungs of the workers, resulting in workers being prone to occupational diseases such as pneumonia and silicosis, and even possibly inducing lung cancer in severe cases. In order to improve the working environment of workers and reduce the health risks brought by dust, air purification equipment usually needs to be installed in a dust workshop. In the existing air purification equipment, generally, a filter screen arranged inside it is used to block and adsorb dust particles in the air, so as to maintain the cleanliness of the air in the workshop. However, since the filter screen is installed inside the equipment and is not easy to clean and maintain, if it is not cleaned in a timely and effective manner, its filtering effect will gradually decrease, and even may become ineffective due to blockage, affecting the overall performance of the air purification equipment. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a multiple air purification equipment for a dust workshop, which can form multiple air purifications and can clean the filter screen filtration area without disassembling the equipment.

[0004] A multiple air purification equipment for a dust workshop in the present invention includes an air inlet box body, a purification box body, and an air outlet box body arranged in sequence from front to back; an inertial collision filtration area and a filter screen filtration area located behind the inertial collision filtration area are arranged in the purification box body. A water tank is arranged at the bottom of the inertial collision filtration area. The filter screen filtration area includes a first filter screen, a second filter screen, and a cleaning device; the cleaning device includes a moving cleaning brush mechanism and a dust suction mechanism. The moving cleaning brush mechanism is arranged between the first filter screen and the second filter screen, and the moving cleaning brush mechanism can move in the up and down direction and contact the surfaces of the first filter screen and the second filter screen. The dust suction mechanism includes a dust suction pipe, a dust suction pump, and a dust outlet pipe. The opening of the dust suction pipe extends into the bottom between the first filter screen and the second filter screen and faces upward, and the dust outlet pipe extends below the liquid level of the water tank.

[0005] Further, a drain pipe is arranged at the bottom of the water tank, the dust outlet pipe is obliquely inserted below the liquid level of the water tank, and the dust suction mechanism can be used to form a turbulent flow when the water tank is draining.

[0006] Further, the inertial collision filtering area includes an inertial collision device and an upper deflector. The inertial collision device includes a first driving element, a first transmission assembly, a first inertial collision mechanism, and a second inertial collision mechanism. Both the first inertial collision mechanism and the second inertial collision mechanism include a first rotating shaft, a second rotating shaft, and a belt. The belt is sleeved on the first rotating shaft and the second rotating shaft. The first rotating shaft is located in the middle of the purification box body, and the second rotating shaft is located below the liquid level of the water tank. The first driving element can drive the two first rotating shafts to rotate through the first transmission assembly, so that the two belts rotate on the corresponding first rotating shafts and second rotating shafts respectively; the upper deflector is located at the upper part of the purification box body, and the bottom end of the upper deflector extends into the space between the first inertial collision mechanism and the second inertial collision mechanism.

[0007] Further, the upper deflector is inclined backward from top to bottom, and both the first inertial collision mechanism and the second inertial collision mechanism are inclined forward from top to bottom.

[0008] Further, a liquid supplement device is arranged on the purification box body. The liquid supplement device includes a water tank arranged outside the purification box body, a liquid supplement pipeline connected to the water tank, and a liquid supplement spray head arranged inside the purification box body.

[0009] Further, the liquid supplement spray head is arranged at the top inside the purification box body. The spraying direction of the liquid supplement spray head is from front to back, and the spraying port of the liquid supplement spray head faces the upper part of the upper deflector.

[0010] Further, the mobile cleaning brush mechanism includes a second driving element, a second transmission assembly, a guiding assembly, and a sliding rod. The second driving element can drive the sliding rod to move in the up and down direction through the second transmission assembly. The guiding assembly is used to guide the moving direction of the sliding rod. A brush is arranged on each of the front and rear sides of the sliding rod, and the end parts of the two brushes respectively contact the surfaces of the first filter screen and the second filter screen.

[0011] Further, an air inlet pipeline and an air inlet fan are arranged on the air inlet box body. An air inlet grille is arranged at the air inlet of the air inlet pipeline. The air inlet fan is used to suck external air into the air inlet box body through the air inlet pipeline; an air outlet pipeline and an air outlet fan are arranged on the air outlet box body. An air outlet grille is arranged at the air outlet of the air outlet pipeline. The air outlet fan is used to discharge the air inside the air outlet box body through the air outlet pipeline.

[0012] Further, the air inlet grille is connected to the air inlet in a detachable manner, and the air outlet grille is connected to the air outlet in a detachable manner.

[0013] Further, it further includes a support frame which is arranged at the lower parts of the air inlet box body, the purification box body and the air outlet box body.

[0014] The beneficial effects of the present invention are as follows:

[0015] (1) The air inlet box body, the purification box body and the air outlet box body of the present invention are divided into three modules, which are convenient for assembly, disassembly and maintenance. The air containing dust passes through the air inlet box body, the inertial collision filtration area, the filter screen filtration area and the air outlet box body in sequence, and can form multiple air purifications.

[0016] (2) The two belts of the present invention rotate on the corresponding first rotating shaft and second rotating shaft respectively, and both belts are partially immersed in the water tank, so the surfaces of the two belts are wet. When the air containing dust rushes into the inertial collision filtration area at a high speed, under the guiding action of the upper guide plate, the first inertial collision mechanism and the second inertial collision mechanism, an airflow with a sharp turn is formed. Part of the dust collides with the belt due to inertia and is adsorbed by the wet surface. The rotation of the belt will also cause this part of the dust adsorbed on the belt surface to enter the water tank. Part of the dust collides with the liquid surface of the water tank due to the guiding action of the upper guide plate and inertia, and is directly absorbed by the water in the water tank. Therefore, the inertial collision filtration area can remove part of the dust and reduce the subsequent purification burden.

[0017] (3) When the equipment needs to be shut down for maintenance and the first filter screen and the second filter screen need to be cleaned, the dust on the filter screen surface is brushed off by moving the cleaning brush mechanism. At the same time, a negative pressure is formed by relying on the dust suction mechanism to suck air, and the brushed-off dust is sucked in and discharged into the water tank to prevent the brushed-off dust from flying again. By setting the cleaning device, the filter screen filtration area can be cleaned without disassembling the equipment. When the equipment needs to be shut down for maintenance and the liquid in the water tank needs to be replaced, first turn on the dust suction mechanism. The dust suction pump sucks air and discharges it into the water tank from the dust outlet pipe, stirring the water flow to form a turbulent flow, which can make part of the dust attached to the water tank wall resuspend. Then open the valve of the drain pipe, and the suspended dust is discharged together with the water flow, improving the self-cleaning ability of the water tank. And stirring the water flow can also prevent the dust from accumulating and precipitating at the drain outlet, ensuring the smooth discharge of the sewage and avoiding blocking the drain pipe. After the liquid discharge is completed, it is necessary to supplement the liquid into the water tank. The clean liquid in the water tank is sprayed onto the upper guide plate through the liquid supplement spray head. The upper guide plate blocks the liquid and guides the liquid to fall into the water tank, which can clean the upper guide plate while supplementing the liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] Such as Figures 1 - 3As shown in the figure, a multiple air purification device for a dust workshop in this embodiment includes an air inlet box body 1, a purification box body 2, and an air outlet box body 3 arranged in sequence from front to back; an inertial collision filtering area 21 and a filter screen filtering area 22 located behind the inertial collision filtering area 21 are arranged in the purification box body 2. A water tank 211 is arranged at the bottom of the inertial collision filtering area 21. The filter screen filtering area 22 includes a first filter screen 221, a second filter screen 222, and a cleaning device; the cleaning device includes a moving cleaning brush mechanism 223 and a dust suction mechanism 224. The moving cleaning brush mechanism 223 is arranged between the first filter screen 221 and the second filter screen 222. The moving cleaning brush mechanism 223 can move in the up and down direction and contact the surfaces of the first filter screen 221 and the second filter screen 222. The dust suction mechanism 224 includes a dust suction pipe 2241, a dust suction pump 2242, and a dust outlet pipe 2243. The opening of the dust suction pipe 2241 extends into the bottom between the first filter screen 221 and the second filter screen 222 and the opening faces upward. The dust outlet pipe 2243 extends below the liquid level of the water tank 211.

[0029] In this embodiment, the inertial collision filtering area 21 includes an inertial collision device and an upper diversion plate 213. The inertial collision device includes a first driving element 214, a first transmission assembly 215, a first inertial collision mechanism 216, and a second inertial collision mechanism 217. Both the first inertial collision mechanism 216 and the second inertial collision mechanism 217 include a first rotating shaft, a second rotating shaft, and a belt. The belt is sleeved on the first rotating shaft and the second rotating shaft. The first rotating shaft is located in the middle of the purification box body 2. The second rotating shaft is located below the liquid level of the water tank 211. The first driving element can drive the two first rotating shafts to rotate through the first transmission assembly 215, so that the two belts rotate on the corresponding first rotating shaft and second rotating shaft respectively; the upper diversion plate 213 is located in the upper part of the purification box body 2. The bottom end of the upper diversion plate 213 extends between the first inertial collision mechanism 216 and the second inertial collision mechanism 217. The first driving element 214 can be a motor, and the first transmission assembly 215 can adopt belt drive, chain drive, or gear drive.

[0030] The air inlet box body 1, the purification box body 2, and the air outlet box body 3 are divided into three modules, which are convenient for assembly, disassembly, and maintenance. The air containing dust passes through the air inlet box body 1, the inertial collision filtering area 21, the filter screen filtering area 22, and the air outlet box body 3 in sequence, and can form multiple air purifications.

[0031] Since the two belts rotate on the corresponding first rotating shaft and second rotating shaft respectively, and both belts are partially immersed in the water tank 211, the surfaces of the two belts are wet. When the air containing dust rushes into the inertial collision filtration area 21 at high speed, an airflow with a sharp turn is formed under the guiding action of the upper deflector 213, the first inertial collision mechanism 216 and the second inertial collision mechanism 217. Part of the dust collides with the wet surface of the belt due to inertia and is adsorbed. The rotation of the belt will also cause this part of the dust adsorbed on the belt surface to enter the water tank 211. Part of the dust collides with the liquid surface of the water tank 211 due to the guiding action of the upper deflector 213 and inertia, and is directly absorbed by the water in the water tank 211. Therefore, the inertial collision filtration area 21 can remove part of the dust and reduce the subsequent purification burden.

[0032] The filtration holes of the second filter screen 222 are smaller than those of the first filter screen 221. When the air passing through the inertial collision filtration area 21 passes through the filter screen filtration area 22, the filter screen filtration area 22 can double-filter the air through the first filter screen 221 and the second filter screen 222 to ensure the cleanliness of the air flowing towards the air outlet box body 3.

[0033] When the equipment needs to be shut down for maintenance and the first filter screen 221 and the second filter screen 222 need to be cleaned, the dust on the surface of the filter screen is brushed off by moving the cleaning brush mechanism 223. At the same time, a negative pressure is formed by relying on the dust suction mechanism 224 to suck air, and the brushed-off dust is sucked in and discharged into the water tank 211 to prevent the brushed-off dust from flying again. By setting the cleaning device, the filter screen filtration area can be cleaned without disassembling the equipment.

[0034] In this embodiment, a drain pipe 212 is provided at the bottom of the water tank 211, and the dust outlet pipe 2243 is inserted obliquely below the liquid surface of the water tank 211. The dust suction mechanism 224 can be used to form a turbulent flow when the water tank 211 drains.

[0035] When the equipment needs to be shut down for maintenance and the liquid in the water tank 211 needs to be replaced, first turn on the dust suction mechanism 224. The dust suction pump 2242 sucks air and discharges it into the water tank 211 from the dust outlet pipe, stirring the water flow to form a turbulent flow, which can resuspend some of the dust attached to the wall of the water tank 211. Then open the valve of the drain pipe 212, and the suspended dust is discharged together with the water flow, improving the self-cleaning ability of the water tank 211. And stirring the water flow can also prevent the dust from accumulating and settling at the drain outlet, ensuring the smooth discharge of the sewage and avoiding blocking the drainage pipeline. The dust outlet pipe 2243 being inserted obliquely below the liquid surface of the water tank 211 can further improve the stirring effect on the water flow.

[0036] In this embodiment, the upper deflector 213 is inclined backward from top to bottom, and both the first inertial collision mechanism 216 and the second inertial collision mechanism 217 are inclined forward from top to bottom.

[0037] The inclined settings of the upper deflector 213, the first inertial collision mechanism 216, and the second inertial collision mechanism 217 can guide the flow direction of the air flow.

[0038] In this embodiment, a liquid replenishing device 23 is provided on the purification box body 2. The liquid replenishing device 23 includes a water tank 231 disposed outside the purification box body 2, a liquid replenishing pipeline 232 connected to the water tank 231, and a liquid replenishing spray head 233 disposed inside the purification box body 2.

[0039] In this embodiment, the liquid replenishing spray head 233 is disposed at the top inside the purification box body 2. The spraying direction of the liquid replenishing spray head 233 is from front to back, and the spraying port of the liquid replenishing spray head 233 faces the upper part of the upper deflector 213.

[0040] After the liquid drainage is completed, it is necessary to replenish the liquid in the water tank 211. The clean liquid in the water tank 231 is sprayed onto the upper deflector 213 through the liquid replenishing spray head 233. The upper deflector 213 blocks the liquid and guides the liquid to fall into the water tank 211, which can clean the upper deflector 213 while replenishing the liquid.

[0041] The water tank 211 has the functions of cleaning the belts of the first inertial collision mechanism 216 and the second inertial collision mechanism 217, directly absorbing the dust that impacts the liquid surface due to inertia, preventing the dust suction mechanism 224 from causing secondary dust flying, and receiving the liquid for cleaning the upper deflector 213 by the liquid replenishing spray head 233.

[0042] In this embodiment, the mobile cleaning brush mechanism 223 includes a second driving element 2231, a second transmission assembly 2232, a guiding assembly 2233, and a sliding rod 2234. The second driving element 2231 can drive the sliding rod 2234 to move in the up and down direction through the second transmission assembly 2232. The guiding assembly 2233 is used to guide the movement direction of the sliding rod 2234. A brush 2235 is disposed on each of the front and rear sides of the sliding rod 2234, and the end portions of the two brushes 2235 respectively contact the surfaces of the first filter screen 221 and the second filter screen 222.

[0043] The second driving element 2231 can be a motor. The second transmission assembly 2232 can adopt a lead screw. The slide bar 2234 and the lead screw form a lead screw nut pair. The guiding assembly 2233 is used to guide the up-and-down movement of the slide bar 2234. The guiding assembly 2233 can be a guide rail with a length along the up-and-down direction. The axis of the slide bar 2234 is along the left-and-right direction. A guiding assembly 2233 is respectively arranged at the left and right ends of the slide bar 2234. Connecting structures that are slidably matched with the guide rail are respectively arranged at the left and right ends of the slide bar 2234. By driving the lead screw to rotate through the second driving element 2231, the slide bar 2234 slides up and down along the lead screw. During the sliding process, the two brushes 2235 on both sides of the slide bar 2234 respectively contact the surfaces of the first filter screen 221 and the second filter screen 222, and brush off the surface dust.

[0044] In this embodiment, an air inlet pipeline 11 and an air inlet fan 12 are arranged on the air inlet box body 1. An air inlet grille 13 is arranged at the air inlet of the air inlet pipeline 11. The air inlet fan 12 is used to suck external air into the air inlet box body 1 through the air inlet pipeline 11. An air outlet pipeline 31 and an air outlet fan 32 are arranged on the air outlet box body 3. An air outlet grille 33 is arranged at the air outlet of the air outlet pipeline 31. The air outlet fan 32 is used to discharge the air inside the air outlet box body 3 through the air outlet pipeline 31.

[0045] The air inlet fan 12 and the air outlet fan 32 cooperate to ensure the speed and direction of air flow. The air inlet grille 13 can block larger fluff, sundries, etc. from entering the equipment.

[0046] In this embodiment, the air inlet grille 13 is connected to the air inlet in a detachable manner, and the air outlet grille 33 is connected to the air outlet in a detachable manner. The air inlet grille 13 and the air outlet grille 33 are arranged outside the equipment, which is convenient for disassembly and cleaning.

[0047] In this embodiment, a support frame 4 is further included. The support frame 4 is arranged below the air inlet box body 1, the purification box body 2, and the air outlet box body 3.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
