Description

Technical Field

[0001] This utility model belongs to the field of workshop dust purification and ventilation technology, and in particular relates to a workshop dust purification and ventilation system with wind speed adjustment function. Background Technology

[0002] A workshop dust purification and ventilation system with wind speed regulation is an integrated device that combines mechanical ventilation and air purification technology to collect, transport, treat and discharge pollutants such as dust, smoke and harmful gases generated in the production workshop. It can also adjust the wind speed according to the amount of dust in the workshop by means of wind speed regulation.

[0003] Traditional workshop dust purification and ventilation devices typically use fans to draw air from the workshop into a purification chamber, where dust is filtered and purified through multi-stage filtration modules before being discharged back into the workshop. However, this method uses multiple filter cartridges directly, which quickly accumulate a large amount of dust with continuous use, requiring frequent filter replacements. This not only increases the workload for workers but also raises air purification costs. Utility Model Content

[0004] The purpose of this invention is to provide a workshop dust purification and ventilation system with wind speed adjustment function. By setting up a purification mechanism, specifically, the air entering the purification chamber mixes with water mist sprayed from the nozzles. The water mist adsorbs a large amount of dust in the air and causes it to settle onto the slope, thus filtering out a large amount of dust. The filtered air then passes through two activated carbon filter elements and is finally discharged into the workshop through the outlet duct. This method can improve the service life of the activated carbon filter elements, eliminating the need for frequent replacements and reducing operating costs. It solves the problem of traditional workshop dust purification and ventilation devices that use multi-stage filtration modules to filter and purify dust. Because multiple filter elements are used directly for filtration, with continuous use, the filter elements quickly accumulate a large amount of dust, leading to frequent filter replacements and increased operating costs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a workshop dust purification and ventilation system with wind speed adjustment function, including a purification box, with support legs fixedly connected to the four corners of the bottom of the purification box, an air inlet pipe fixedly connected to the top of the purification box, a fan installed inside the air inlet pipe, an air outlet pipe fixedly connected to the bottom right side of the purification box, a fan installed inside the air outlet pipe, and further including: The purification mechanism is located inside the purification chamber. It includes a diversion pipe inside the chamber, with several fixed pipes fixedly connected to its outer surface. Several atomizing nozzles are fixedly connected to the top of each fixed pipe. A water supply pipe is fixedly connected to the left side of the diversion pipe. Two frames are inserted into the right side of the purification chamber, and activated carbon filter elements are fixedly connected inside each frame. Because the air is first sprayed, a large amount of dust particles are filtered out. Therefore, the activated carbon filter elements only need to filter the remaining dust in the air, thus extending their service life. The diversion pipe is located at the bottom of the air inlet pipe, and the water supply pipe extends through the purification box to the outside on the left side. The left side of the water supply pipe is used to connect to the water pipe.

[0006] Furthermore, a bracket is fixedly connected to the right side of the diversion pipe, and the top of the bracket is fixedly connected to the top of the inner wall of the purification box. The right side of the frame penetrates the purification box and extends to the outside. The activated carbon filter is used for secondary air filtration. The bracket is used to support the diversion pipe, and the frame and the activated carbon filter are integrally set.

[0007] Furthermore, a baffle is fixedly connected to the top of the inner wall of the purification box, and a baffle is fixedly connected to the bottom of the inner wall of the purification box. A slope is provided on the left side of the baffle, and a drain pipe is fixedly connected to the left side of the bottom of the purification box. The baffle is used to block the sprayed water mist and can also block the air, so that the air and water mist mix for a longer time. The ramp is used to guide the settled dust, and the drain pipe is used to discharge wastewater.

[0008] Furthermore, there is a space between the bottom of the first baffle and the slope, and a space between the top of the second baffle and the purification box. The first baffle is used to block and guide the intake air. As the water mist increases, a certain water flow will form on the slope, and the water flow will be discharged through the drain pipe along with the dust.

[0009] Furthermore, a cover plate is fixedly connected to the right side of the frame, and a sealing ring is fitted on the left side of the cover plate. The left side of the sealing ring contacts the right side of the purification box. Two support strips are provided at the bottom of the frame, and the support strips are fixedly connected to the inner wall of the purification box. The support strips are used to support the frame during installation, and the sealing ring is used to seal the cover plate and the purification box.

[0010] Furthermore, the purification chamber has arc-shaped plates on both the front and back sides on the right side. A pressing rod is fixedly connected to the side of each arc-shaped plate that is close to the other. A slot is formed inside the arc-shaped plate, and a threaded shaft is inserted into the slot. The threaded shaft is fixedly connected to the surface of the purification chamber. An internally threaded handle is threaded onto the outer surface of the threaded shaft. Fixing blocks are hinged to the top and bottom of the arc-shaped plates, and these fixing blocks are fixedly connected to the surface of the purification chamber. The threaded shaft is connected to the purification chamber by welding, and the inner diameter of the slot is slightly larger than the diameter of the threaded shaft.

[0011] Furthermore, the left side of the frame contacts the right side of the second baffle, the outer surface of the extrusion rod contacts the right side of the cover plate, and a handle is fixedly connected to the right side of the cover plate; the extrusion rod will press the cover plate, and the sealing ring will be tightly attached to the surface of the purification box, thereby achieving a sealing effect.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a purification mechanism. Specifically, the air entering the purification chamber mixes with the water mist sprayed from the nozzle. The water mist adsorbs a large amount of dust in the air and causes it to settle onto the slope, thereby filtering out a large amount of dust. The filtered air then passes through two activated carbon filters and is finally discharged into the workshop through the exhaust pipe. This method can improve the service life of the activated carbon filters, eliminating the need for frequent replacements and reducing operating costs.

[0013] 2. This utility model uses an arc-shaped plate. Specifically, after the frame and activated carbon filter are inserted into the right side of the purification box, the sealing ring on the cover plate will contact the surface of the purification box. Then, the arc-shaped plate is flipped so that the extrusion rod contacts the surface of the cover plate. The internal threaded handle is then connected to the threaded shaft clockwise to lock and fix the arc-shaped plate. At this time, the extrusion rod will press the cover plate, and the sealing ring will be tightly attached to the surface of the purification box, thereby achieving a sealing effect and preventing dust from overflowing.

Several fixed pipes 22 are fixedly connected to the outer surface of the diversion pipe 21. Several atomizing nozzles 23 are fixedly connected to the top of the fixed pipes 22. A water supply pipe 24 is fixedly connected to the left side of the diversion pipe 21. Two frames 25 are inserted into the right side of the inside of purification chamber 1. Activated carbon filter elements 251 are fixedly connected inside the frames 25. The air entering purification chamber 1 mixes with the water mist sprayed from the nozzles 23. The water mist adsorbs a large amount of dust in the air and settles it onto the slope 17, thereby filtering a large amount of dust in the air. The filtered air then passes through the two activated carbon filter elements 251 and is finally discharged to the workshop from the air outlet 14. This method can improve the service life of the activated carbon filter elements 251, eliminating the need for frequent replacement and reducing operating costs. The diversion pipe 21 is located at the bottom of the air inlet duct 12. The water supply pipe 24 passes through purification chamber 1 on the left and extends to the outside. The left side of the water supply pipe 24 is used to connect to a water pipe.

[0020] A bracket 211 is fixedly connected to the right side of the diversion pipe 21. The top of the bracket 211 is fixedly connected to the top of the inner wall of the purification box 1. The right side of the frame 25 passes through the purification box 1 and extends to the outside. The activated carbon filter element 251 is used for secondary filtration of air.

[0021] A baffle 15 is fixedly connected to the top of the inner wall of the purification box 1, and a baffle 2 16 is fixedly connected to the bottom of the inner wall of the purification box 1. A ramp 17 is provided on the left side of the baffle 2 16, and a drain pipe 13 is fixedly connected to the bottom left side of the purification box 1. The ramp 17 is used to guide the settled dust, and the drain pipe 13 is used to discharge sewage.

[0022] There is a space between the bottom of baffle 15 and the ramp 17, and a space between the top of baffle 2 16 and the purification box 1. Baffle 15 is used to block and guide the intake air.

[0023] A cover plate 252 is fixedly connected to the right side of the frame 25, and a sealing ring 253 is fitted on the left side of the cover plate 252. The left side of the sealing ring 253 contacts the right side of the purification box 1. Two support bars 254 are provided at the bottom of the frame 25, and the support bars 254 are fixedly connected to the inner wall of the purification box 1.

[0024] The purification chamber 1 has arc-shaped plates 3 on both the front and back sides. A pressing rod 31 is fixedly connected to the side of each arc-shaped plate 3 that is close to the other. A slot 32 is opened inside the arc-shaped plate 3, and a threaded shaft 33 is inserted into the slot 32. The threaded shaft 33 is fixedly connected to the surface of the purification chamber 1. An internally threaded handle 34 is threaded onto the outer surface of the threaded shaft 33. Fixing blocks 35 are hinged to the top and bottom of the arc-shaped plates 3, and are also fixedly connected to the surface of the purification chamber 1. After the frame 25 and activated carbon filter element 251 are inserted into the right side of the purification chamber 1, the sealing ring 253 on the cover plate 252 will contact the surface of the purification chamber 1. Then, the arc-shaped plate 3 is flipped so that the pressing rod 31 contacts the surface of the cover plate 252. The internally threaded handle 34 is then threaded clockwise onto the threaded shaft 33, locking the arc-shaped plate 3 in place. At this time, the pressing rod 31 will press the cover plate 252, causing the sealing ring 253 to adhere tightly to the surface of the purification chamber 1, thus achieving a sealing effect and preventing dust from overflowing.

[0025] The left side of frame 25 contacts the right side of baffle 2 16, the outer surface of extrusion rod 31 contacts the right side of cover plate 252, and a handle is fixedly connected to the right side of cover plate 252.

[0026] One specific application of this embodiment is: In use, the water supply pipe 24 is connected to a water pipe, allowing water to flow through the supply pipe 24 to the distribution pipe 21, which then distributes the water flow into several fixed pipes 22. Water mist is then sprayed out through nozzles 23. By starting the fan 121, air from the workshop is drawn into the purification box 1. Dust in the air comes into contact with the water mist, which adsorbs and settles a large amount of dust onto the slope 17. As the amount of water mist increases, a certain water flow forms on the slope 17, which, along with the dust, is discharged through the drain pipe 13. This method can quickly filter a large amount of dust from the air, and the baffle... Baffle 15 is used to block the air, allowing the air to contact the water mist for a longer time. During the spraying process, fan 2141 is started to draw the air out of the purification box 1. The air then flows from the bottom of baffle 15 and enters the activated carbon filter 251 from the top of baffle 216. At this time, the air will be filtered again by two activated carbon filters 251 and finally discharged into the workshop from the air outlet 14. Since the air has been sprayed first, a large number of dust particles have been filtered. Therefore, activated carbon filter 251 only needs to filter the remaining dust in the air, thereby improving the service life of activated carbon filter 251. When the activated carbon filter element 251 needs to be replaced, turn the internal threaded handle 34 counterclockwise to disassemble it, releasing the arc plate 3 from its fixation. Then, flip the arc plate 3 to disengage the pressing rod 31 from the cover plate 252. Pull the cover plate 252 out along with the frame 25 and the activated carbon filter element 251. Insert the new frame 25 into the right side of the purification box 1. At this time, the support bar 254 will support the frame 25. After the frame 25 is aligned, the sealing ring 253 on the cover plate 252 will engage with the filter element. The surface of the purification box 1 is in contact with the surface of the cover plate 252. Then, the arc plate 3 is flipped over so that the extrusion rod 31 contacts the surface of the cover plate 252. The arc plate 3 is inserted into the threaded shaft 33 through the slot 32. Then, the internal threaded handle 34 is connected to the threaded shaft 33 clockwise, thereby extruding the arc plate 3. At this time, the extrusion rod 31 will extrude the cover plate 252, and the sealing ring 253 will be tightly attached to the surface of the purification box 1, thereby achieving a sealing effect and preventing dust from overflowing. The installation of the activated carbon filter element 251 is then completed. It should be noted that the control of both fan 121 and fan 2141 in this application adopts the program set in the control panel and the automatic control method is achieved by inputting relevant parameters as needed. The setting of this control method can be realized by existing technology. At the same time, fan 121 and fan 2141 achieve dynamic adjustment of air volume and wind speed by integrating sensor monitoring and frequency conversion control technology.
