[0002] Concrete, abbreviated as concrete, is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; mixed with water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering. When producing concrete, a large amount of raw materials such as sand, cement, and stone are needed. These raw materials will generate a lot of dust during use, causing environmental pollution and endangering the health of workers.

[0003] At present, spraying and dust reduction is usually carried out by installing spraying equipment such as fog cannons and nozzles at dust hazard concentration points such as silos and factory gates. However, the amount of dust will only exceed the dust control red line when raw materials enter or exit the factory, and dust reduction is required. If the spraying equipment is always turned on, it will cause a large amount of water and electricity consumption. If staff are arranged separately to control the opening and closing of the spraying equipment, the workload of the staff will increase, and then there is a problem that it is difficult to automatically reduce dust according to the amount of dust generated. Utility Model Content

In this embodiment, the dust detector 4 is a laser dust meter; the control panel 5 is installed on the rack 1, and the control panel 5 is electrically connected to both the dust detector 4 and the water pump 32.

[0034] The staff places the rack 1 at the concentrated points of dust hazards such as the silo and the factory gate. The dust detector 4 detects the dust concentration in the ambient air in real time. When the dust detector 4 detects that the dust concentration in the ambient air is greater than the dust control red line, the dust detector 4 sends an electrical signal to the control panel 5.

After receiving the electrical signal, the control panel 5 controls the water pump 32 to stop, and the spraying of the nozzle 2 can be stopped, realizing the real-time detection of the dust concentration at the concentrated points of dust hazards such as the silo and the factory gate, and being able to control whether to supply water according to the dust concentration in the ambient air, so as to realize automatic dust reduction, effectively improving the problem that it is difficult to perform automatic dust reduction according to the dust generation amount.

[0035] Refer to Figure 1 , Figure 2The collecting mechanism 6 is installed on the frame 1. The collecting mechanism 6 is used to collect water mist. The collecting mechanism 6 includes a water collecting bucket 61, a sedimentation box 62 and a filter assembly 63. The water collecting bucket 61 is installed on the frame 1. The water collecting bucket 61 is located below the nozzle 2. The water collecting bucket 61 is used to collect water mist in the ambient air. The water collecting bucket 61 includes a vertical rod 611, a sliding sleeve 612, a support rod 613, a waterproof cloth 614 and a control member 615. The vertical rod 611 is vertically installed on the frame 1. The sliding sleeve 612 is slidably mounted on the vertical rod 611. The support rod 613 is hingedly installed with multiple intervals on the sliding sleeve 612 in the circumferential direction. The waterproof cloth 614 is installed on the vertical rod 611 , one end of the original sleeve 612 of multiple support rods 613 is hingedly installed on the waterproof cloth 614 at circumferential intervals, and the bottom of the waterproof cloth 614 is connected to the sedimentation box 62 through a corrugated hose. In this embodiment, the waterproof cloth 614 is made of polyurethane, which has the characteristics of light weight, softness, wear resistance, and waterproofness; the control component 615 is installed on the vertical rod 611, and the control component 615 is used to drive the sleeve 612 to slide on the vertical rod 611.

The piston rod of the electric push rod 6151 is connected to the sleeve 612, and the electric push rod 6151 is electrically connected to the control panel 5.

[0036] When the control panel 5 controls the water pump 32 to start, it also controls the piston rod of the electric push rod 6151 to retract, so that the sliding sleeve 612 slides upward on the vertical rod 611, and the sliding sleeve 612 drives the multiple support rods 613 to move upward to an expanded state, and the multiple support rods 613 can open the waterproof cloth 614, and the water mist sprayed by the nozzle 2 can fall into the expanded waterproof cloth 614 for collection; when the control panel 5 controls the water pump 32 to stop, it also controls the piston rod of the electric push rod 6151 to extend, so that the sliding sleeve 612 slides downward on the vertical rod 611, and the sliding sleeve 612 drives the multiple support rods 613 to move downward to a retracted state, and the multiple support rods 613 can drive the waterproof cloth 614 to be retracted, so that the water collecting bucket 61 can be conveniently unfolded or retracted according to whether water mist is sprayed to reduce dust, thereby reducing the space occupied by the water collecting bucket 61 when dust reduction is not required, and improving the problem that the water collecting bucket 61 is always in an expanded state and affects passing vehicles and pedestrians.

[0037] Reference Figure 1 , Figure 2 The sedimentation box 62 is installed on the frame 1, and the sedimentation box 62 is located above the water tank 31. The side wall of the sedimentation box 62 close to the top wall is connected with the water tank 31 through a pipeline.

[0038] When the nozzle 2 sprays water mist for dust reduction, the waterproof cloth 614 unfolds to collect the falling water mist. Then, the water in the waterproof cloth 614 flows into the sedimentation tank 62 under the action of gravity for sedimentation. The water after sedimentation then flows into the water tank 31 from the side wall of the sedimentation tank 62 near the top wall, and is pumped and utilized by the water supply pump 32, thereby realizing the reuse of water sources, effectively improving the utilization rate of water sources. Moreover, the connection between the sedimentation tank 62 and the water tank 31 is arranged on the side wall of the sedimentation tank 62 near the top wall, so that the upper layer of water source after static sedimentation in the sedimentation tank 62 enters the water tank 31, improving the cleanliness of the water entering the water tank 31 from the sedimentation tank 62.

[0039] Refer to Figure 1 、 Figure 3 A sewage outlet 7 is connected and installed at the bottom of the sedimentation tank 62, and a sewage valve 8 is installed on the sewage outlet 7. In this embodiment, the sewage valve 8 is a gate valve, and a cover plate is hinged and installed at the top of the sedimentation tank 62.

[0040] When it is necessary to clean the sedimentation tank 62, the staff opens the cover plate at the top of the sedimentation tank 62 and opens the sewage valve 8, then the inside of the sedimentation tank 62 can be cleaned, and the sundries to be cleaned are discharged from the sewage outlet 7, effectively improving the convenience for the staff to clean the sedimentation tank 62.

[0041] Refer to Figure 1 、 Figure 3 A filtering component 63 is installed on the sedimentation tank 62. The filtering component 63 is used to filter the water flowing from the sedimentation tank 62 into the water tank 31. The filtering component 63 includes a conical sleeve 631 and a filter net 632. The conical sleeve 631 is arranged in a conical shape and is hollow inside. The conical sleeve 631 is inserted at the connection between the sedimentation tank 62 and the water tank 31. The filter net 632 is covered on the conical sleeve 631 and blocks the opening of the conical sleeve 631. In this embodiment, the filter net 632 is a stainless steel net, and rubber is covered on the outer side wall of the conical sleeve 631 to enhance the friction between the conical sleeve 631 and the sedimentation tank 62.

[0042] Before the water in the sedimentation tank 62 enters the water tank 31, the filter net 632 filters the impurities in the water, further improving the cleanliness of the water entering the water tank 31 from the sedimentation tank 62. When it is necessary to clean the filter net 632, the staff pulls out the conical sleeve 631 from the connection between the sedimentation tank 62 and the water tank 31, then the filter net 632 can be taken out of the sedimentation tank 62 for cleaning or replacement. Then, the cleaned or replaced conical sleeve 631 is inserted into the connection between the sedimentation tank 62 and the water tank 31, and the filter net 632 can block the connection between the sedimentation tank 62 and the water tank 31, effectively improving the convenience for the staff to clean or replace the filter net 632.

[0043] The implementation principle of a dust real-time detection and automatic dust reduction device in an embodiment of this application is as follows: The dust detector 4 detects the dust concentration in the ambient air. After detecting that the dust concentration in the ambient air is greater than the dust control red line, the dust detector 4 sends an electrical signal to the control panel 5. The control panel 5 controls the water pump 32 to start and simultaneously controls the water collecting hopper 61 to unfold, so that water can be sprayed from the nozzle 2 for spray dust reduction. The sprayed water is collected by the water collecting hopper 61 and then utilized. After the dust detector 4 detects that the dust concentration in the ambient air is lower than the dust control red line, it sends an electrical signal to the control panel 5 again. The control panel 5 controls the water pump 32 to stop supplying water and simultaneously controls the water collecting hopper 61 to retract, thereby realizing automatic dust reduction according to the dust concentration in the ambient air and effectively improving the problem that it is difficult to perform automatic dust reduction according to the dust generation amount.
