Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a dust-catching net device for building construction. Background Technique

[0002] . During the construction process at a building construction site, a large amount of dust is often generated and scattered everywhere with the air, seriously affecting the surrounding environment. Although there are also devices in the prior art to prevent the spread of dust, such as the Chinese patent (CN207554101U): a special dust-catching net for coal mines. This patent forms a water film on the dust-catching net through an overflow tank above the dust-catching net, and the overflow tank forms a water film on the dust-catching net through an overflow port to perform secondary adsorption and cleaning of dust, further improving the dust removal efficiency. At the same time, the sewage is filtered through a filter screen and then recycled by a circulating pump, saving energy.

[0003] However, after the filter screen is used for a long time, it will be blocked by large-particle mixtures and cannot complete the recycling of water. At the same time, tiny impurities enter the circulating pump through the filter screen, which is likely to cause damage to the circulating pump. Summary of the Utility Model

[0024] Embodiment 1

[0025] Please refer to the attached Figures 1-4 , this application provides a dust-catching net device for building construction, including a frame 1, a water supply mechanism 2, a dust-catching net 3, a dust collection mechanism 4 and a reflux mechanism 5. The dust-catching net 3 is laid flat in the middle of the frame 1. The water supply mechanism 2 is arranged on the top of the frame 1 and is used to discharge water towards the dust-catching net 3 so that the dust is adsorbed and collected. A diversion groove 6 is arranged directly below the dust-catching net 3 on the frame 1, and the diversion groove 6 is inclined;

[0026] The dust collection mechanism 4 includes a collection tank 401 and a dust baffle 402. The collection tank 401 is located below the dust-catching net 3, and a number of the dust baffles 402 are equidistantly distributed on the bottom plate of the collection tank 401;

[0027] The reflux mechanism 5 includes a reflux pipe 501, an air inlet pipe 502 and an air pump 503. The reflux pipe 501 is vertically arranged in the water body of the collection tank 401. The lower end of the reflux pipe 501 is communicated with the collection tank 401. The air inlet pipe 502 is arranged on the side wall of the lower end of the reflux pipe 501 in the water body of the collection tank 401. The air inlet pipe 502 passes through the side wall of the collection tank 401 and is connected to the air pump 503. The water outlet end of the reflux pipe 501 is connected to the water supply mechanism 2.

[0028] Before the device of the present application is used, first move the device to the dust suppression site, then supplement enough clean water in the water delivery mechanism 2, turn on the switch of the water delivery mechanism 2, and use the water delivery mechanism 2 to discharge water towards the dust-catching net 3 so that the flying dust is adsorbed and collected. The mixture adsorbed on the dust-catching net 3 flows along the dust-catching net 3 into the diversion trough 6 through the water flow on the dust-catching net 3. The diversion trough 6 guides the sewage containing the mixture to one side of the collection trough 401. It is possible that the mixture in the sewage accumulates on one side of the collection trough 401, which is convenient for subsequent cleaning. By arranging a plurality of dust baffle plates 402 in the collection trough 401, the mixture in the sewage is intercepted at multiple levels, improving the sewage treatment effect. Preferably, the length of the collection trough 401 is greater than the length of the water trough 201. A return pipe 501 is vertically arranged on the other side where the mixture in the collection trough 401 accumulates. The bottom side wall of the return pipe 501 communicates with the air inlet pipe 502. When the water surface in the collection trough 401 submerges the air inlet pipe 502, turn on the air pump 503. The air pump 503 fills the water in the return pipe 501 with air through the air inlet pipe 502. The water with bubbles enters the water delivery mechanism 2 upward along the return pipe 501, realizing the reuse of water, saving resources, and preventing impurities from entering the air pump 503 and damaging the air pump 503, improving the practicability of the device. Preferably, the air outlet end of the air inlet pipe 502 is bent upward so that the movement direction of the discharged gas is upward.

[0029] Specifically, the water delivery mechanism 2 includes a water trough 201, a water delivery pipe 202, and a liquid outlet nozzle 203. The water trough 201 is fixedly installed on the top of the frame 1. The bottom of the water trough 201 is provided with the water delivery pipe 202 passing through the top plate of the frame 1. The water delivery pipe is provided with the liquid outlet nozzle 203 facing the dust-catching net 3. The water trough 201 is installed on the top of the frame 1. The water in the water trough 201 passes through the water delivery pipe 202 and is sprayed from the liquid outlet nozzle 203 onto the dust-catching net 3, adsorbing the scattered dust on the dust-catching net 3, improving the dust removal efficiency. Moreover, the liquid outlet nozzle 203 continuously sprays water on the dust-catching net 3, washing off the mixture on the dust-catching net 3, preventing the dust-catching net 3 from being blocked by the mixture, and improving the adsorption effect of the dust-catching net 3.

[0030] Specifically, an elbow 7 is provided at the water outlet end of the return pipe 501. The angle between the elbow 7 and the return pipe 501 is 45°. The pipe orifice of the elbow 7 is located in the water body of the water tank 201. A connecting rod 8 is provided on the side wall of the water tank 201. The connecting rod 8 is fixedly connected to the return pipe 501 through a pipe support 9. Designing the water outlet end of the return pipe 501 as an elbow 7 is beneficial for the water with bubbles in the return pipe 501 to flow into the water tank 201. Moreover, the angle between the elbow 7 and the return pipe 501 is 45°, which separates the water and bubbles, and the water and bubbles enter the water body of the water tank 201 through the pipe orifice of the elbow 7, preventing the bubbles from running out of the water tank 201 and wasting resources. The functions of the connecting rod 8 and the pipe support 9 are to fix the return pipe 501 on the water tank 201, facilitating the water with bubbles in the return pipe 501 to flow into the water tank 201 and improving the stability of the return pipe 501.

[0031] Embodiment 2

[0032] Please refer to the attached Figures 1-4 In this embodiment, the difference from Embodiment 1 is that a support plate 10 is provided on the frame 1, and an oscillator 11 is installed on the support plate 10 and acts on the dust collection net 3. By oscillating the dust collection net 3 through the oscillator 11, the mixture on the dust collection net 3 is shaken off, preventing the dust collection net 3 from being blocked and affecting the dust adsorption effect of the dust collection net 3. The function of the support plate 10 is to support and fix the oscillator 11, improving the stability of the oscillator 11.

[0033] Specifically, a filter screen 12 is provided on the dust baffle 402. The filter screen 12 on the dust baffle 402 can better separate and filter the water and the mixture, improving the solid-liquid separation effect of the sewage and being beneficial to the recycling of water.

[0034] Specifically, the diameter of the return pipe 501 is 50 - 80 mm. Setting the diameter of the return pipe 501 to 50 - 80 mm ensures that the water flow with bubbles can enter the return pipe 501 and rise through the return pipe 501, realizing the recycling of water and saving resources.

[0035] Specifically, rollers 13 are provided at the bottom of the frame 1. Installing rollers 13 at the bottom of the frame 1 facilitates the movement of the device and improves the practicability of the device.

[0036] The above are only the specific implementation manners of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the claims.
