Technical Field

[0001] The utility model belongs to the technical field of dust reduction devices in coal mines, and particularly relates to a non-powered adding device for a wetting type dust reduction agent. Background Art

[0002] Wetting-type dust suppressants primarily reduce the surface tension of water by adding surfactants, thereby increasing the wettability of water on dust particles and achieving dust reduction. These dust suppressants are widely used in dust control applications such as coal mines and construction sites, often employing a spraying method. The key to their dosing mechanism is how to mix the dust suppressant with water in the correct proportion and evenly spray it over the desired area.

[0003] Existing automatic dust suppressant adding devices require external energy and power, which not only consumes energy and increases equipment costs, but also has a complex structure, a high failure rate, and is difficult to use and maintain. Other automatic dust suppressant adding devices achieve addition by sucking in the dust suppressant through the negative pressure formed by a jet water column, but there is a problem that the amount of addition is difficult to accurately control.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-3As shown, a non-powered adding device for a wettable dust suppressant comprises a tank body 1, a tank cover 2, a mixing box 10, a hydraulic bag 22 and a floating plate 24. The tank cover 2 is arranged at the upper end of the tank body 1, and the mixing box 10 is fixed to the side wall of the tank body 1. The hydraulic bag 22 and the floating plate 24 are located in the tank body 1, and the floating plate 24 is located below the hydraulic bag 22. The diameter of the floating plate 24 is smaller than the smallest inner diameter of the tank body 1 to ensure that the floating plate 24 can move freely in the tank body 1. Three legs 21 are evenly arranged around the bottom surface of the tank body 1.

[0020] The tank cover 2 is provided with a feeding funnel 3, an exhaust pipe 5 and a return joint 7, the feeding funnel 3 is provided with a feeding stop valve 4, the exhaust pipe 5 is provided with an exhaust stop valve 6, the return joint 7 is provided with a return stop valve 8, the feeding funnel 3, the exhaust pipe 5 and the lower end of the return joint 7 are connected to the hydraulic bag 22, the mixing box 10 is provided with a water inlet 11 on one side and a water outlet 12 on the other side, the water outlet 12 is provided with a stop valve 25, and the top surface is provided with a feeding joint 11. The feed joint 14 is provided with a flow regulating valve 13 for adjusting the flow of the dust suppressant to achieve precise control of the liquid ratio. The water outlet joint 15 is provided with a water outlet stop valve 16. The return joint 7 is connected to the feed joint 14 through a return hose 9. The bottom of the tank body 1 is provided with a water inlet joint 18 and a drain pipe 19. The water outlet joint 15 is connected to the water inlet joint 18 through a water inlet pipe 17. The drain pipe 19 is provided with a drain stop valve 20.

[0021] The working process of this utility model:

[0022] During use, the water inlet 11 is externally connected to the working face water supply system or the water outlet of the booster pump, and the water outlet 12 is externally connected to the pipeline of the coal mining machine dust suppression water supply system. Before supplying water, the drainage stop valve 20 is opened, and the regulated water 24 in the tank body 1 is drained and then closed. The feeding stop valve 4 and the exhaust stop valve 6 are opened, and the return stop valve 8, the water outlet stop valve 16 and the stop valve 25 are closed. According to the calculation of the staff, the dust suppressant is added to the feeding funnel 3, and the dust suppressant then enters the feeding air bag 22 until it is full. During the feeding process, the gas in the feeding air bag 22 is discharged from the exhaust pipe 5 to ensure that the dust suppressant can smoothly enter the feeding air bag 22;

[0023] After the addition is completed, the feeding stop valve 4 and the exhaust stop valve 6 are closed, the return material stop valve 8 is opened, and the water supply system starts to supply water. Water enters the mixing box 10 from the water inlet 11. When the water in the mixing box 10 is full, the water enters the tank body 1 from the water outlet joint 15 along the water inlet pipe 17 and the water inlet joint 18 under the water pressure of the water supply system. As the regulating water 24 in the tank body 1 increases, the float 23 floats and rises. When it rises to support the feeding air bag 22, as the regulating water 24 continues to increase, the float 23 rises to squeeze the feeding air bag 22, so that the dust suppressant is discharged from the return material joint. The head 7 enters the mixing box 10 along the return hose 9 and the feed connector 14, mixes with the water in the mixing box 10 to form the liquid required for dust reduction, and completes the liquid proportioning operation. During the proportioning process, the flow regulating valve 13 can be adjusted according to demand to accurately control the proportion of the dust reduction liquid in real time. After the dust reduction liquid proportioning is completed, the stop valve 25 is opened, and the liquid is discharged from the water outlet 12 to supply the pipeline of the downstream coal mining machine dust reduction water supply system for use. During the whole process, the above process is repeated to obtain the required dust reduction liquid continuously to meet the downstream needs.
