Description

A dust suppression device for construction Technical Field

[0001] This utility model belongs to the field of dust suppression technology, specifically relating to a dust suppression device for building construction. Background Technology

[0002] Construction sites generate a large amount of dust, and the overflow of this dust can cause environmental pollution. Therefore, dust suppression treatment is necessary. In existing technologies, most dust suppression is achieved by spraying a mist of water.

[0003] The applicant currently uses a mist-like water curtain to suppress dust at the construction site, which results in a waste of water resources. In addition, the mist-like water curtain causes the road surface to become wet when construction vehicles pass by, and the wet soil sticks to the tires of the construction vehicles, causing a large amount of soil to fall onto the city roads near the construction site, which requires special personnel to clean up. Summary of the Invention

[0004] The purpose of this invention is to provide a dust suppression device for construction work, thereby solving the problems mentioned in the background section. The dust suppression device provided by this invention not only achieves dust suppression but also conserves water resources and prevents roads from becoming damp.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for construction, comprising water tanks and spray components symmetrically arranged on both sides of a road. The spray components include a mounting bracket, a connecting pipe mounted on the mounting bracket, and several nozzles mounted on the connecting pipe. A centrifugal pump is installed in the middle of one side of the water tank, with the inlet end of the centrifugal pump connected to the water tank and the outlet end of the centrifugal pump connected to the connecting pipe via a water pipe.

[0006] To make the water stream from the nozzle flat, thus reducing the need for nozzles, the nozzle is further designed with a flat structure.

[0007] To increase the water tank's surface area and prevent water from spilling onto the outside of the tank, a flared opening is connected to the top of the tank.

[0008] To further obstruct the water flow and prevent it from splashing outside the water tank, a baffle is connected above the horn on the side away from the water spray assembly.

[0009] In order to regularly drain the water in the tank and clean the sludge, a drain outlet is connected to the bottom of the tank, and a valve is installed at the end of the drain outlet.

[0010] In order to automatically replenish water when the water level is lower than the set value, and to prevent the water in the tank from decreasing due to evaporation or slight spillage, a water replenishment pipe is installed at the top of the water tank, and a float level gauge is installed at the outlet of the water replenishment pipe.

[0011] To reduce the impact of the water flow on the water in the tank and facilitate the settling of dust particles in the tank, a second, downward-sloping buffer plate is installed inside the flared nozzle, with the connecting edge of the second buffer plate located on the side close to the water spray assembly.

[0012] In order to reduce the impact of water flow on the water in the tank and facilitate the settling of dust particles in the tank, a first buffer plate inclined downward is installed inside the flared mouth below the second buffer plate, and the connecting edge of the first buffer plate is located on the side away from the water spray assembly.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a nozzle to spray water to form a water belt that adsorbs dust, thereby treating dust. The water sprayed from the nozzle is recycled through a water tank, which can reduce the waste of water resources and prevent roads from becoming wet.

[0015] 2. The nozzle of this utility model has a flat structure, which makes the water flow from the nozzle flat, thereby reducing the use of the nozzle.

[0016] 3. The upper end of the water tank of this utility model is connected to a flared mouth to increase the water receiving area of ​​the water tank. A baffle is connected above the flared mouth on the side away from the water spray component. The baffle blocks the water flow and prevents the water from splashing outside the water tank.

[0017] 4. The water tank of this utility model is equipped with a water supply pipe at the top and a float level gauge at the outlet of the water supply pipe. When the water level is lower than the set value, water is automatically replenished to prevent the water in the tank from decreasing due to evaporation or a little spillage.

[0018] 5. The inside of the flared opening of this utility model is equipped with a second buffer plate that is inclined downwards, and a first buffer plate that is inclined downwards is installed below the second buffer plate, which reduces the impact force of the water flow on the water in the water tank and is conducive to the settling of dust particles in the water tank.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please refer to Figures 1-2. This utility model provides the following technical solution: A dust suppression device for construction, including a water tank 1 symmetrically arranged on both sides of the road and a water spraying assembly. The water spraying assembly includes a mounting bracket 7, a connecting pipe 6 installed on the mounting bracket 7, and several parallel nozzles 5 installed on the connecting pipe 6. During installation, the angle of the nozzles 5 is adjusted by rotating the connecting pipe 6 so that the water sprayed from the nozzles 5 falls into the water tank 1. Then the connecting pipe 6 is fixed. A centrifugal pump 2 is installed in the middle of one side of the water tank 1. The centrifugal pump 2 is a CDLF4-20 model from Southern Pump Industry. The water inlet of the centrifugal pump 2 is connected to the water tank 1, and the water outlet of the centrifugal pump 2 is connected to the connecting pipe 6 through a water pipe.

[0025] By adopting the above technical solution, this utility model uses the nozzle 5 to spray water to form a water belt to adsorb dust, thereby achieving the treatment of dust. The water sprayed from the nozzle 5 is recycled through the water tank 1, which can reduce the waste of water resources on the one hand, and prevent the road from becoming wet on the other hand.

[0026] It should be noted that the dust consists of relatively fine particles, and its incorporation into the water will not affect the operation of centrifugal pump 2.

[0027] Specifically, nozzle 5 has a flat structure.

[0028] By adopting the above technical solution, the water flow sprayed from nozzle 5 is made flat, thereby reducing the use of nozzle 5.

[0029] Specifically, the upper end of water tank 1 is connected to a flared port 3.

[0030] By adopting the above technical solution, the water-receiving area of ​​water tank 1 is increased, preventing water from spilling onto the outside of water tank 1.

[0031] Specifically, the bottom of the water tank 1 is connected to a drain outlet 8, and a valve is installed at the end of the drain outlet 8.

[0032] The above technical solution is used to periodically drain the water in water tank 1 and clean the silt.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that, specifically, a baffle 4 is connected to the side of the horn 3 away from the water spray assembly.

[0035] By adopting the above technical solution, the water flow is blocked by the baffle 4, further preventing water from splashing onto the outside of the water tank 1.

[0036] Example 3

[0037] The difference between this embodiment and embodiment 1 is that: specifically, a water supply pipe 9 is installed at the upper end of the water tank 1, a float level gauge 10 is installed at the outlet end of the water supply pipe 9, and the inlet end of the water supply pipe 9 is connected to tap water.

[0038] By adopting the above technical solution, when the water level is lower than the set value, automatic water replenishment is achieved, avoiding the water in the water tank 1 from decreasing due to evaporation or slight spillage.

[0039] Example 4

[0040] The difference between this embodiment and embodiment 1 is that, specifically, a downwardly inclined second buffer plate 12 is installed inside the horn mouth 3, and the connecting edge of the second buffer plate 12 is located on the side close to the water spray assembly.

[0041] By adopting the above technical solution, the impact force of the water flow on the water in the water tank is reduced by the second buffer plate 12, which is conducive to the settling of dust particles in the water tank 1.

[0042] Specifically, inside the horn 3, below the second buffer plate 12, a first buffer plate 11 is installed at an angle downwards, and the connecting edge of the first buffer plate 11 is located on the side away from the water spray assembly.

[0043] By adopting the above technical solution, the impact force of water flow on the water in water tank 1 is further reduced, which is conducive to the settling of dust particles in the water tank.

[0044] In summary, this invention uses nozzle 5 to spray water to form a water stream that adsorbs dust, thus treating dust. The water sprayed from nozzle 5 is recycled through water tank 1, reducing water waste and preventing roads from becoming damp. The nozzle 5 has a flat structure, making the water stream flat and reducing its usage. A flared nozzle 3 is connected to the upper end of water tank 1, increasing its water-receiving area. A baffle 4 is connected above the flared nozzle 3, away from the spray assembly, to block the water flow and prevent spillage. A water supply pipe 9 is installed at the upper end of water tank 1, and a float level gauge 10 is installed at the outlet of the water supply pipe 9. When the water level falls below a set value, automatic water replenishment is achieved, preventing the water in tank 1 from decreasing due to evaporation or minor spillage. The inside of the flared mouth 3 of this utility model is equipped with a second buffer plate 12 that is inclined downwards, and a first buffer plate 11 that is inclined downwards is installed below the second buffer plate 12. This reduces the impact force of the water flow on the water in the water tank 1 and is conducive to the settling of dust particles in the water tank.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
