Description

Technical Field

[0001] The utility model relates to the technical field of a multi-stage dust reduction device for a mixing station, in particular to a multi-stage dust reduction device for a mixing station. Background Art

[0002] The mixing station is composed of a mixing device, an aggregate supply device, a powder storage device, a metering device, a control device and external supporting equipment. The mixing station is mainly used in concrete construction projects to mix raw materials. Concrete refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. Usually, concrete refers to cement as a cementitious material, sand and stone as aggregates; mixed with water in a certain proportion, and the obtained cement concrete, also known as ordinary concrete, is widely used in civil engineering. The backstage material yard of the mixing station is in a semi-closed state, and a large amount of dust will be generated when sand and gravel are poured in. The diffusion of dust will cause dust to fly in the material yard. The suspended dust leads to a poor working environment in the material yard, and the air is turbid due to the flying dust, which seriously affects the workers' work. The workers' inhalation of dust during work will also affect their health. At present, most mixing stations have taken certain dust removal measures for their dust emissions, and often use fog cannons and fog machines for dust reduction operations; when using fog cannons, the dust reduction coverage area of ​​the device is large, and the use effect is good in material yards with a large amount of dust, but because it uses an annular nozzle and the water output is difficult to control, the water output is too much during use, and continuous use will cause serious water accumulation in the material yard, which is inconvenient for workers to walk. The air in the concrete mixing station contains dust, which leads to environmental pollution of the concrete mixing station. Dust reduction operations are carried out through dust reduction devices. The height of the spray barrel on the general mobile dust reduction device is fixed, and the height of the sprayed water mist cannot be adjusted. It is inconvenient to use, and the dust-carrying air cannot be further collected or processed. The dust falls to the ground. If the dust removal equipment does not continue to work, the dust falling to the ground will form dust again after drying, and the dust removal effect cannot be achieved. Therefore, this patent proposes a multi-stage dust reduction device for mixing stations to solve such problems. During use, multi-stage adjustment can be achieved, which is convenient to use and has a wide range of applications. Utility Model Content

[0018] Reference Figure 1-2 The utility model provides a multi-stage dust reduction device for a mixing station, including a rotating nut 1, the inner wall of the rotating nut 1 is threadedly connected with a water tank 2, the middle part of the rotating nut 1 is fixedly connected with an inner auxiliary pipe 6, the bottom of the inner auxiliary pipe 6 is fixedly connected with a bottom movable cover 7, the circumferential movably connected with the water tank 2, the middle part of the bottom movable cover 7 is fixedly connected with a water pipe 8, the middle part of the water pipe 8 is fixedly connected with a water pump 9, the top of the water pipe 8 is fixedly connected with a water storage tank 10, the middle part of the water storage tank 10 is fixedly connected with a water spray pipe 5, the outside of the water storage tank 10 is sleeved with a top fixed pipe 4, and the bottom of the top fixed pipe 4 is fixedly connected with a sliding ring 3.

[0019] The structure of the water spray pipe 5 is three-layered, and the water spray pipe 5 is evenly distributed on the circumference of the water storage tank 10. After the water spray pipe 5 is fixedly connected to the water storage tank 10, the pitch angle of the water spray pipe 5 can be adjusted so that the distance of the water spray can be changed.

[0020] The middle of the water spray pipe 5 is connected with the top fixed pipe 4, and the circumference of the middle of the top fixed pipe 4 is evenly provided with round holes. The bottom movable cover 7 is adapted to the water delivery tank 2, and the structure of the rotating nut 1 is a cylinder, and a round hole is provided on the top of the rotating nut 1; as the rotating nut 1 rotates, the bottom movable cover 7 can move downward with the rotating nut 1, so that the water pressure inside the water delivery tank 2 is constant, and the spraying distance of the water from the top is not affected.

[0021] The water spray pipe 5 is made of rubber and moves in the circular hole of the top fixed pipe 4. The structure of the water delivery tank 2 is a cylinder, and the rotating nut 1 moves up and down outside the water delivery tank 2, and the outside of the water delivery tank 2 is provided with a thread; the rotation of the rotating nut 1 can drive the movement of the top fixed pipe 4 and the movement of the inner auxiliary pipe 6, so that the water spray dust suppression device works stably.

[0022] The working principle of the utility model is as follows: when performing dust reduction in a mixing station, the dust reduction device is placed in the middle of the mixing station, and then the water pump 9 is turned on to pump water, and the water at the bottom of the water pipe 8 is pumped into the inside of the water storage tank 10, and then discharged. During use, the rotating nut 1 is located outside the water tank 2 and can be rotated. While rotating, the rotating nut 1 moves up and down on the top of the water tank 2, so that the top fixed pipe 4 and the inner auxiliary pipe 6 move up and down. Circular holes are evenly opened in the middle of the top fixed pipe 4, and a water spray pipe 5 is arranged in the middle of the circular hole.
