Description

Technical Field

[0001] This application relates to the field of workshop dust removal technology, and in particular to an environmentally friendly dust removal system for concrete production workshops. Background Technology

[0002] Concrete production workshops generate dust such as cement ash, fly ash, mineral powder, and other dust during the production process. High-pressure spraying is commonly used to suppress this dust. The principle of high-pressure spraying dust suppression is to use high-pressure spraying equipment to pressurize water, producing water mist particles with a diameter of 1-10 μm. These water mist particles adsorb dust suspended in the air, causing them to agglomerate and settle under gravity, thus achieving the dust suppression effect.

[0003] Chinese utility model patent CN209491970U discloses a dust removal system for a concrete batching workshop. The system includes a water storage tank and a water pump. The water storage tank contains water for dust removal. A buffer tank and an air pump are located on one side of the water storage tank, connected to the buffer tank. The water pump drives water flow from the water storage tank to the buffer tank. A main pipe is installed on the workshop ceiling, connected to multiple branch pipes. The main pipe is connected to the buffer tank. Multiple spray nozzles are installed on the branch pipes, each equipped with an atomizing nozzle. The atomizing nozzles spray water mist to adsorb and settle dust particles, thereby reducing the amount of dust in the concrete batching workshop.

[0004] Regarding the aforementioned technologies, the inventors discovered that after the water mist adsorbs dust, it begins to sink. When it sinks to the height of the workers, it is easily inhaled by them, causing harm to their health. Summary of the Invention

[0005] In order to reduce the amount of settling dust inhaled by workers and thus reduce the harm to their health, this application provides an environmentally friendly dust removal system for concrete production workshops.

[0006] The environmentally friendly dust removal system for a concrete production workshop provided in this application adopts the following technical solution:

[0007] An environmentally friendly dust removal system for a concrete production workshop includes a dust collection box located on the top surface of the workshop. The bottom surface of the dust collection box is equipped with an electrically powered anode plate and a cathode plate. The anode plate can be rotated into the dust collection box. A filter assembly is installed inside the dust collection box.

[0008] By adopting the above technical solution, both the anode plate and the cathode plate are energized, creating an electric field between them. This electric field ionizes the air, and the negative ions generated combine with dust particles, causing the dust particles to become negatively charged and move towards the anode plate, eventually adhering to it. After the dust adheres to the anode plate, it rotates into the dust collection box, where the filter assembly absorbs and filters the dust adhering to the anode plate, reducing the possibility of dust settling in the workshop. This reduces the amount of settling dust inhaled by workers and minimizes the harm to their health.

[0009] Optionally, the bottom surface of the dust collection box is provided with a dust suction port, and both the anode plate and the cathode plate are disposed in the dust suction port. The anode plate is rotatably connected to the dust suction port. The filter assembly includes a filter bag and a fan. The filter bag and the fan are connected. The fan is used to absorb the gas in the dust collection box into the filter bag and filter it.

[0010] By adopting the above technical solution, when the anode plate rotates to the point where the side with dust adhering to it is located in the dust collection box, the fan is started. The fan sucks up the dust on the anode plate and discharges it into the filter bag. The filter bag filters the dust and discharges the filtered gas, thereby completing the cleaning of the dust on the anode plate.

[0011] Optionally, multiple suction ports are provided, and the multiple suction ports are equidistantly spaced along the length of the dust collection box. Multiple sets of anode plates and cathode plates are provided, and the multiple sets of anode plates and cathode plates are respectively disposed in multiple suction ports.

[0012] By adopting the above technical solution, multiple sets of anode plates and cathode plates work simultaneously, and multiple anode plates adsorb dust at the same time, thereby improving the efficiency of dust adsorption.

[0013] Optionally, the filter assembly further includes multiple suction cylinders, each located directly above a plurality of suction ports, and all of the suction cylinders are connected to a fan.

[0014] By adopting the above technical solution, during the operation of the anode plate and cathode plate, the anode plate and cathode plate are spaced apart, and the dust collection cylinder is located above the gap between them. At this time, the fan is started, and the fan absorbs the air in the workshop, which speeds up the airflow between the anode plate and the cathode plate, thereby improving the efficiency of the anode plate in absorbing dust. At the same time, another part of the gas directly enters the fan, and the fan then discharges it into the filter bag, where the filter bag filters it, which also improves the efficiency of dust absorption.

[0015] Optionally, the dust collection cylinder is connected to a branch air inlet pipe, the dust collection box is provided with a main air inlet pipe, and multiple branch air inlet pipes are connected to the main air inlet pipe, and the main air inlet pipe is connected to the filter bag.

[0016] By adopting the above technical solution, when the fan is started, the dust on multiple anode plates passes through the corresponding dust collection cylinders, enters the corresponding branch air inlet pipes, and then gathers into the main air inlet pipe. Finally, it enters the filter bag from the main air inlet pipe, thereby filtering the dust.

[0017] Optionally, the length direction of the vacuum cleaner is parallel to the length direction of the vacuum outlet, and the bottom ends on both sides of the length direction of the vacuum cleaner are inclined away from each other.

[0018] By adopting the above technical solution, the bottom ends on both sides of the dust collection cylinder along its length are tilted away from each other, thereby guiding the airflow.

[0019] Optionally, the dust collection box is provided with a worm gear and a first drive motor. The first drive motor is used to drive the worm gear to rotate. A rotating shaft is fixedly connected to each of the multiple anode plates. The rotating shaft is rotatably connected to the corresponding dust suction port. One end of each of the multiple rotating shafts is coaxially fixedly connected to a worm wheel. The multiple worm wheels mesh with the worm gear.

[0020] By adopting the above technical solution, the first drive motor is started, which drives the worm to rotate. The worm drives multiple worm wheels to rotate, and the multiple worm wheels drive multiple rotating shafts to rotate. The multiple rotating shafts drive multiple anode plates to rotate towards the dust collection box, thereby causing the side of the multiple anode plates with dust adhering to them to rotate into the dust collection box.

[0021] Optionally, the dust collection box is equipped with a second drive motor and two lead screws. The second drive motor is used to drive the two lead screws to rotate. Each of the two lead screws is threaded with a slider. A sliding rod is fixedly connected between the two sliders. Brush bristles are fixedly connected to the sliding rod, which is located above the anode plate.

[0022] By adopting the above technical solution, the second drive motor is started, which drives the two lead screws to rotate. The two lead screws drive the two sliders on them to slide, and the two sliders drive the slide rod to slide. The slide rod drives the brush bristles to sweep away the dust adhering to the anode plate, so that it floats in the dust collection box, making it easier for the fan to suck away the dust.

[0023] Optionally, each of the two lead screws is coaxially fixedly connected to a sprocket at one end, and the two sprockets are connected by a chain. The transmission shaft of the second drive motor is coaxially fixedly connected to one of the lead screws.

[0024] By adopting the above technical solution, the second drive motor is started, which drives one lead screw to rotate. The lead screw drives another lead screw to rotate through a chain, thereby completing the drive of the two lead screws.

[0025] Optionally, a water tank is provided on the ground, with an air inlet and an air outlet. An air outlet pipe is fixedly connected to the air outlet end of the fan, and the other end of the air outlet pipe extends into the air inlet.

[0026] By adopting the above technical solution, the gas filtered by the filter bag enters the water tank through the gas outlet pipe, where it undergoes secondary filtration. The gas filtered by the water tank is then discharged into the workshop through the gas outlet, thereby completing the purification of the air in the workshop.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Both the anode and cathode plates are energized, creating an electric field between them. This electric field ionizes the air, and the resulting negative ions combine with dust particles, causing them to become negatively charged and move towards the anode plate, eventually adhering to it. Once dust adheres to the anode plate, it rotates into the dust collection box, where the filter assembly absorbs and filters the dust adhering to the anode plate, reducing the likelihood of dust settling in the workshop. This reduces the amount of settling dust inhaled by workers and minimizes the harm to their health.

[0029] 2. When the anode plate rotates to the point where the side with the adhering dust is inside the dust collection box, start the fan. The fan will suck up the dust on the anode plate and discharge it into the filter bag. The filter bag will filter the dust and discharge the filtered gas, thus completing the cleaning of the dust on the anode plate.

[0030] 3. During the operation of the anode and cathode plates, the anode and cathode plates are spaced apart, and the dust collection cylinder is located above the gap between them. At this time, the fan is started, and the fan draws in the air in the workshop, which speeds up the airflow between the anode and cathode plates, thereby improving the dust absorption efficiency of the anode plates. At the same time, another part of the gas directly enters the fan, and the fan then discharges it into the filter bag, where the filter bag filters it, which also improves the dust absorption efficiency.

[0045] The second drive motor 44 is started, which drives one lead screw 41 to rotate. One lead screw 41 drives another lead screw 41 to rotate via a chain. The two lead screws 41 drive the sliders 45 on them to slide. The two sliders 45 drive the slide rod 46 to slide.

The filter assembly 5 is located inside the dust collection box 1 and is used to absorb and filter the dust in the dust collection box 1. The water tank 6 is located on the ground. The gas discharged from the filter assembly 5 enters the water tank 6 for secondary filtration. The gas that has completed secondary filtration is discharged into the workshop 7.

[0047] Reference Figure 2 The filter assembly 5 includes multiple suction cylinders 51 located inside the dust collection box 1. Each suction cylinder 51 corresponds to a specific suction port 11, with each suction cylinder 51 positioned directly above its corresponding suction port 11 and above the slide rod 46. The top surface of each suction cylinder 51 is sealed. The length of the suction cylinder 51 is parallel to the length of the suction port 11, and the bottom ends on both sides of the suction cylinder 51 are angled away from each other. A connecting rod 52 is fixedly connected to the top surface of each suction cylinder 51, and the other end of the connecting rod 52 is fixedly connected to the inner top wall of the dust collection box 1.

A dust outlet hole 12 is opened on the side wall of the dust collection box 1 near the fan 57. The other end of the air outlet pipe 59 passes through the dust outlet hole 12.

[0049] When the fan 57 is started, the dust in the dust collection box 1 passes through the dust suction cylinder 51, the branch air inlet pipe 55 and the main air inlet pipe 53 in sequence and enters the filter bag 56. The air filtered by the filter bag 56 is discharged from the air inlet pipe 58 and passes through the fan 57 and the air outlet pipe 59, and enters the water tank 6 for further purification.

[0050] Reference Figure 2 Water tank 6 is set on the ground. The top surface of water tank 6 has an air inlet 61 and an air outlet 62. The bottom end of the air outlet pipe 59 passes through the air inlet 61 and extends into water tank 6.

[0051] The implementation principle of an environmentally friendly dust removal system for a concrete production workshop according to an embodiment of this application is as follows: the electric field between the anode plate 21 and the cathode plate 22 ionizes the air, and the negative ions generated by ionization combine with the dust particles, causing the dust particles to become negatively charged and move towards the anode plate 21, and finally adhere to the anode plate 21.

[0052] The first drive motor 34 is started, which drives the worm gear 31 to rotate. The worm gear 31 drives multiple worm wheels 32 to rotate, which in turn drive multiple rotating shafts 23 to rotate. These shafts 23 then drive multiple anode plates 21 to rotate, thus rotating the anode plates 21 to a horizontal position with the dust-covered side facing the inside of the dust collection box 1. The second drive motor 44 is started, which drives a lead screw 41 to rotate. This lead screw 41 drives another lead screw 41 to rotate via a chain. The two lead screws 41 cause sliders 45 to slide, which in turn cause a sliding rod 46 to slide. The sliding rod 46 causes the brush bristles 47 to rotate, thereby sweeping off the dust adhering to the anode plates 21 and allowing it to float inside the dust collection box 1.

[0053] When the fan 57 is started, the dust in the dust collection box 1 passes through the dust suction cylinder 51, the branch air inlet pipe 55 and the main air inlet pipe 53 in sequence and enters the filter bag 56. The air filtered by the filter bag 56 is discharged from the air inlet pipe 58, passes through the fan 57 and the air outlet pipe 59, and enters the water tank 6 for further purification. Finally, the purified gas is discharged into the workshop 7.
