Description

Technical Field

[0001] The invention relates to the technical field of dust removal devices, in particular to environmentally friendly dust removal equipment for green buildings. Background Art

[0002] A large amount of dust will be generated during construction, causing the entire processing site to be in a state of serious pollution, which is contrary to the construction concept of green buildings. The existing technology usually uses spray dust reduction equipment to reduce dust in the air during construction. This method is more effective, but it also causes a lot of resource consumption.

[0003] The use of spraying to reduce dust at construction sites can easily cause the construction environment and the ground to become damp, affecting the construction progress. In addition, after a period of time, as the water evaporates, the dust on the ground will float in the air again, making it impossible to remove the dust effectively. Summary of the invention

The present invention has a novel structure and improves the dust removal effect by combining dust suction and dust reduction. The inhaled dust gas is removed from the dust particles by internal spraying, and the spray water can be used again for spraying and dust reduction in the external environment after filtration, thereby improving the dust removal effect and making full use of water resources.

[0006] Furthermore, the filter assembly also includes a scraper, and scrapers are fixed on both sides of the frame corresponding to the gauze passing through the roller shaft, and the scraper is in sliding contact with the upper and lower end surfaces of the gauze.

[0007] Furthermore, the bottom of the middle frame is connected to the water tank, and slide rails are fixed on the inner walls on both sides of the middle frame. The two sides of the gauze slide through the slide rails, and the bottom of the gauze bypasses the bottom of the water tank.

[0008] Furthermore, the spray assembly also includes a rotating layer, a rotating layer is fixed at the bottom of the air inlet layer, the rotating ring is fixedly installed inside the rotating layer, a return pipe is fixed on one side of the rotating layer, and the other end of the return pipe is fixedly connected to the bottom of the water tank.

[0009] Furthermore, the driving assembly also includes a gear ring, a gear ring is fixed to the outer bottom of the rotating ring, one side of the gear ring is meshed with a first gear, a motor is fixed on the surface of the middle frame located at the bottom of the first gear, and the output end of the motor is fixedly connected to the first gear.

[0010] Furthermore, a transmission belt is installed on the output shaft of the motor, and a pulley at the other end of the transmission belt is rotatably installed on the upper end of a roller shaft at the top of one side of the frame through a bearing seat. A first bevel gear is installed on the pulley on the other side of the transmission belt, and a second bevel gear is fixed on the position of the roller shaft corresponding to the first bevel gear, and the first bevel gear is meshingly connected with the second bevel gear.

[0011] Furthermore, a spray plate is fixedly installed inside the flushing pipe, and the spray hole of the spray plate faces upward. A water supply pipe is fixed on one side of the spray plate, and the other end of the water supply pipe passes through the flushing pipe.

[0012] Furthermore, an air outlet is provided on the bottom side of the flushing pipe, and a water baffle is fixed on the outer side of the air outlet.

[0013] Furthermore, four dust suction pipes are equidistantly arranged on the periphery of the air inlet layer, and a dust suction fan is installed inside the dust suction pipes.

[0014] Furthermore, connecting pipes are fixed equidistantly between the rotating ring and the circular ring, and two ends of the connecting pipes are respectively connected to the inside of the rotating ring and the nozzle.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention drives the first gear to rotate through a motor, and the first gear meshes with the gear ring to drive the rotating ring to rotate along the bottom of the rotating layer, and then the ring and the nozzle rotate synchronously. Because the rotating layer is fixedly connected to the air inlet layer, the air inlet layer will also rotate synchronously, and the nozzle and the air inlet pipe are placed in different positions to achieve wider coverage and higher efficiency of dust suction and spraying dust reduction.

[0017] 2. The present invention is driven by a transmission belt, and the first bevel gear rotates and meshes with the second bevel gear, driving the roller shaft to rotate. The roller shaft is an active roller shaft, and through friction with the gauze, the other three roller shafts rotate synchronously, and the gauze is pulled in a circular manner, and the surfaces corresponding to the gauze, the spray pipe and the bottom box are continuously replaced to maintain good permeability, isolate dust particles, and allow water to pass through into the water tank, which is convenient for secondary dust reduction. When the screen passes through the middle frame, it is limited and guided by the inner wall slide rails on both sides of the middle frame to maintain a flat state. When passing through the middle frame, it contacts the upper and lower sets of scrapers, and the scrapers scrape off the wet dust on the surface of the gauze, which is convenient for manual centralized cleaning.

[0018] 3. In the present invention, after the gauze is wrapped around for one circle, the gauze can continue to be used. The scraper not only cleans the surface of the gauze, but also limits the position where the screen passes through the roller shaft, so that the area of ​​the gauze wrapped on the surface of the roller shaft exceeds half of the roller shaft, maintaining sufficient contact area to achieve friction rotation.

[0019] 4. The spray plate of the present invention delivers external water through a water supply pipe, which convects with the air entering the flushing pipe to better adsorb and remove dust. The air with removed dust is sent out from the air outlet to maintain the fluidity of the gas. The sewage generated by the spraying is blocked by a water baffle to prevent it from flowing to the outside and wasting water resources.

[0020] 5. The present invention sucks the air of the construction environment into the air inlet layer through the dust suction fan inside the dust suction pipe. The air flows toward one side of the flushing pipe, and the air is flushed inside the flushing pipe through the spray plate to adsorb and remove dust particles in the air. Through the connection of the connecting pipe, the nozzle can deliver water through the rotating ring and then spray it into the external environment, so as to perform secondary spraying to reduce dust on the construction site to avoid the problem of incomplete dust removal.

[0021] 6. Compared with the prior art, the present invention improves the dust removal effect by combining dust suction and dust reduction. The dust particles are removed from the inhaled dust gas through internal spraying, and the spray water can be used again for spraying and dust reduction in the external environment after filtration, thereby improving the dust removal effect and making full use of water resources.

[0036] In this embodiment, a spray plate 72 is fixedly installed inside the flushing pipe 7, and the spray hole of the spray plate 72 faces upward. A water supply pipe 71 is fixed on one side of the spray plate 72, and the other end of the water supply pipe 71 passes through the flushing pipe 7. An air outlet 73 is opened on the side of the bottom of the flushing pipe 7, and a water retaining plate 74 is fixed on the outside of the air outlet 73. The spray plate 72 delivers external water through the water supply pipe 71, which convects with the air entering the flushing pipe 7 to better absorb and remove dust. The air with dust removed is sent out from the air outlet 73 to maintain the fluidity of the gas.

Connecting pipes 44 are equidistantly fixed to the rotating ring 46 and the circular ring 42, and the two ends of the connecting pipe 44 are respectively connected to the inside of the rotating ring 46 and the nozzle 43. The cooperation between the dust suction pipe 31 and the air inlet layer 3 is the technical principle of the existing vacuum cleaner.

Through the connection of the connecting pipe 44, the nozzle 43 can spray water on the outside environment after delivering water through the rotating ring 46. In the process, the construction site is sprayed for dust reduction for the second time to avoid incomplete dust removal. The first bevel gear 65 rotates and meshes with the second bevel gear 66 through the transmission of the transmission belt 64, driving the roller 51 to rotate. The roller 51 is the active roller 51. Through the friction with the gauze 52, the other three rollers 51 rotate synchronously, and the gauze 52 is pulled in a surrounding manner. The surfaces of the gauze 52 corresponding to the spray pipe and the bottom box are continuously replaced to maintain good permeability, isolate dust particles, and allow water to pass through into the water tank 2, which is convenient for secondary dust reduction. When the screen passes through the middle frame 12 , limited and guided by the inner wall slide rails 121 on both sides of the middle frame 12, it maintains a flat state, and when passing through the middle frame 12, it contacts the upper and lower sets of scrapers 53, and the scrapers 53 scrape off the wet dust on the surface of the gauze 52, which is convenient for manual centralized cleaning, and after circling around for one week, the gauze 52 can continue to be used. The scraper 53 not only cleans the surface of the gauze 52, but also limits the position of the screen passing through the roller 51, so that the area of ​​the gauze 52 wrapped on the surface of the roller 51 exceeds half of the roller 51, and maintains sufficient contact area to realize friction rotation force.
