Description

[0002] To ensure the cleanliness of the mine, a dust suppression spray system is needed to spray a solution of a certain concentration for regular or irregular dust removal. Before dust removal, a spray solution of a specific concentration must be prepared. Currently, most mines use electronic components to control the amount of raw materials used to prepare the spray solution of the required concentration. Specifically, current solution preparation devices extensively use level sensors and weight sensors to control the concentration of the spray solution. However, in engineering conditions such as those using rock dumping machines, the sensitivity of electronic components may decrease or even fail due to factors such as dust. This not only increases the maintenance cost of the solution preparation device but also affects the normal operation or effectiveness of dust removal in the mine. Summary of the Invention

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 and Figure 2 As shown, the mechanical liquid dispensing device of the dust removal spray system in this embodiment includes a box structure 100, a water volume control device 200, a material volume control device 300, a water delivery control device 400, a feeding control device 500, a liquid level control device 600, and a controller 570.

[0031] like Figure 2 As shown, the box structure 100 includes a storage tank 110, a mixing tank 120, a liquid storage tank 130, and a liquid inlet 140. The storage tank 110 is fixed to the middle of one side of the mixing tank 120, and the liquid storage tank 130 is fixed to the other side of the mixing tank 120. The storage tank 110 is smaller than the mixing tank 120, and the horizontal position of the liquid storage tank 130 is lower than the horizontal position of the mixing tank 120 to ensure that the mixing liquid flows into the liquid storage tank 130. The liquid inlet 140 is installed at the lower part of the other side of the mixing tank 120, and the mixing liquid flows into the liquid storage tank 130 through the liquid inlet 140 for later use. The storage tank 110 is used to store solutes such as CaCl2.

[0032] The water volume control device 200 and the material volume control device 300 have the same structure and are respectively installed on both sides of one side of the mixing tank 120. The water volume control device 200 and the material volume control device 300 are respectively used to control the amount of water and material poured into the mixing tank 120.

[0033] The water supply control device 400 is connected to both the water volume control device 200 and the mixing tank 120, and is used to control whether water is supplied to the water volume control device 200.

[0034] The feeding control device 500 is connected to both the material quantity control device 300 and the mixing tank 120, and is used to control whether the amount of material is fed into the material quantity control device 300.

[0035] The liquid level control device 600 is connected to the mixing tank 120 and is used to control the liquid level in the mixing tank 120;

[0036] The controller 570 is installed on the feed control device 500 and is used to control the operation of the water supply control device 400 and the feed control device 500.

[0037] like Figure 3 As shown, the water volume control device 200 includes a water tank 210, a rotating wheel 220, a buffer spring 230, and a weight adjustment frame 240. The weight adjustment frame 240 is connected to the bottom of the water tank 210. The rotating wheel 220 is installed at the right angle connecting the water tank 210 and the weight adjustment frame 240 and is connected to the mixing tank 120, and is used to realize the relative rotation between the water volume control device 200 and the mixing tank 120. The buffer spring 230 is installed at the bottom of the water tank 210 to ensure a small vibration impact when the water tank 210 collides with the mixing tank 120.

[0038] The water tank 210 can rotate 90°. A weight can be placed on the adjusting frame 240 to keep the water tank 210 horizontal when empty. As the water level in the tank increases, it tilts towards the mixing tank 120, pouring water into it. The amount of water in the tank can be adjusted by changing the weight on the adjusting frame 240, thus regulating the amount of water dispensed. When the water tank 210 tilts and collides with the mixing tank 120, the buffer spring 230 cushions the impact. One side of the rotating wheel 220 is welded to the water tank 210, and the other side is welded to the mixing tank 120, allowing the water tank 210 to rotate 90°.

[0039] The material quantity control device 300 includes a storage bin, a second rotating wheel, a second buffer spring, and a second adjusting frame. The second adjusting frame is connected to the bottom of the storage bin. The second rotating wheel is installed at the right angle connecting the storage bin and the second adjusting frame and is connected to the mixing tank 120, and is used to realize the relative rotation between the material quantity control device 300 and the mixing tank 120. The second buffer spring is installed at the bottom of the storage bin to ensure minimal vibration and impact when the storage bin collides with the mixing tank 120. The material quantity control device 300 has the same structure and function as the water quantity control device 200, and its operating principle is also the same.

[0040] like Figure 4As shown, the water supply control device 400 includes a water supply pipe 410, a water supply pipe welding point 420, a water supply pipe jog switch 430, and a counter 440. The outlet of the water supply pipe 410 extends above the water storage tank 210 and is used to supply water into the water storage tank 210. The water supply pipe 410 is preferably a rigid water pipe. The water supply pipe 410 is fixed by the water supply pipe welding point 420, which is connected to the mixing tank 120. The water supply pipe jog switch 430 is located near the welding point of the water supply pipe 410. The water supply pipe jog switch 430 is installed on the water supply pipe 410 and can contact the water storage tank 210. The switching action of the water supply pipe jog switch 430 is achieved by the action of the water storage tank 210. The counter 440 is welded to the water supply pipe welding point 420 and connected to the controller 570.

[0041] Specifically, when the water tank 210 is in a horizontal position, the jog switch 430 of the water supply pipe is open, and the water supply pipe 410 supplies water normally. When the water tank 210 rotates, it actuates the jog switch 430, at which point the jog switch 430 is closed, and the water supply pipe 410 stops supplying water. The counter 440 can be preset to count a number of times. Each time the water tank 210 completes a water-pouring action, it counts once. After reaching the preset number of counts, the controller 570 controls the jog switch 430 to be closed until the controller 570 controls the jog switch 430 to be opened again.

[0042] like Figure 5 As shown, the feeding control device 500 includes a support plate 510, three pulleys 520, a belt 530, several material boxes 540, a feeding control device jog switch 550, and the counter 560. The support plate 510 is connected to the mixing tank 120. The three pulleys 520 are respectively installed on the upper left, upper right, and lower left positions of the support plate 510. The belt 530 is installed on the three pulleys 520, and the inner side of the belt 530 meshes with the three pulleys 520. The several material boxes 540 are fixed to the belt 530 by bolts. On the outer side, the feed control device jog switch 550 is located at the lower right position of the support plate 510. The feed control device jog switch 550 is mounted on the support plate 510 and can contact the storage box 310. The feed control device jog switch 550 is electrically connected to the motor of the three pulleys 520. The switching action of the feed control device jog switch 550 is realized by the action of the storage box 310. The counter 560 and the controller 570 are welded to the support plate 510. The counter 560 and the controller 570 are connected.

[0043] The belt 530 rotates along with the pulley 520, thereby driving the material conveying box 540 to rotate and convey materials. Specifically, when the material storage box is in a horizontal position, the feed control device jog switch 550 is on, the pulley 520 rotates normally, and the material conveying box 540 conveys materials normally; when the material storage box rotates, it drives the feed control device jog switch 550 to operate, at which point the feed control device jog switch 550 is off, the pulley 520 stops rotating, and the material conveying box 540 stops conveying materials. The counter 560 can be preset to count a number of times. Each time the material storage box completes a material unloading action, it counts once. After reaching the preset number of counts, the controller 570 controls the feed control device jog switch 550 to be off until the controller 570 controls the feed control device jog switch 550 to be on again.

[0044] like Figure 6 As shown, the liquid level control device 600 includes a liquid level plate 610, a synchronizing rod 620, a liquid level control device guide rail 630, and a liquid level control device jog switch 640. The liquid level plate 610 is placed inside the stirring tank 120. The density of the material of the liquid level plate 610 is less than that of the stirring liquid, allowing it to float on the stirring liquid. One end of the liquid level plate 610 is connected to the synchronizing rod 620. The synchronizing rod 620 is slidably connected to the liquid level control device guide rail 630 to cooperate in realizing up and down movement. The liquid level control device guide rail 630 is fixed to the stirring tank 120. On the tank 120, the guide rail 630 of the liquid level control device is used to limit the up and down movement of the synchronizing rod 620. The synchronizing rod 620 is provided with several levels (preferably three levels) of liquid level control device jog switches 640 to adjust the synchronizing rod 620 to achieve different liquid levels. Each set of liquid level control device jog switches 640 is provided in two symmetrical sets and is electrically connected to the motors of the water supply pipe 410 and the three pulleys 520 respectively. The up and down movement of the synchronizing rod 620 realizes the synchronous switching of the two sets of liquid level control device jog switches 640.

[0045] The liquid level control device 600 prevents excessive overflow of the stirring liquid, which would lead to waste. A primary liquid level control device jog switch 640 controls a predetermined liquid level in the stirring tank 120. When the liquid level is below the level specified by a primary liquid level control device 600, both sets of jog switches 640 are in the "on" state, meaning the water supply pipe 410 and the pulley 520 controlled by both sets of jog switches 640 operate normally, and water and solute are transported normally to the stirring tank 120, which then operates normally. Conversely, when the liquid level is above the predetermined stirring liquid level, both sets of jog switches 640 are in the "off" state, meaning the water supply pipe 410 and the pulley 520 controlled by both sets of jog switches 640 stop operating, and water and solute are no longer transported to the stirring tank 120. When the liquid level falls below the specified stirring level, the liquid level plate 610 drives the synchronizing rod 620 to turn the two sets of liquid level control device jog switches 640 on, and water and solute continue to be transported into the stirring tank 120.

[0046] The working principle of this invention is as follows:

[0047] First, based on experience, the weights of the first and second weight adjustment frames are set, and the water flow rate of the water supply pipe 410 and the rotation speed of the pulley 520 are adjusted. Adjusting these parameters allows for the adjustment of the required solution concentration. A solute, such as CaCl2, is placed in the storage tank 110 for later use. After the system starts working, the water supply pipe 410 supplies water to the storage tank 210, while the material transport tank 540 transports CaCl2 into the storage tank (manually adding material to the material transport tank 540). When the water level in the storage tank 210 reaches a certain amount, the storage tank 210 is tilted towards the mixing tank 120 to pour the water into the mixing tank 120. When the material level in the storage tank 110 reaches a certain amount, the storage tank 110 is tilted towards the mixing tank 120 to pour the CaCl2 into the mixing tank 120, and the mixing tank 120 begins its mixing operation. After stirring is complete, the resulting stirred solution is transferred to the storage tank 130 through the inlet for later use, thus completing the preparation of a stirred solution of a quantitative concentration.

[0048] The counter 440 and the counter 560 can be preset to count a number of times within a solution preparation cycle, and are both controlled by the controller 570. After the preset number of times is completed, the water supply pipe jog switch 430 and the feed control device jog switch 550 are disconnected, stopping the water and / or feed operation. The counter 440 and the counter 560 count independently, and the solution preparation operation of the next cycle will only begin when all the preset counts within a solution preparation cycle are completed.

[0049] For example, if the counter 440 counts 10 times in one solution preparation cycle and the counter 560 counts 8 times in one solution preparation cycle, then the water tank 210 completes 10 water-pouring actions and the material tank completes 8 material-pouring actions as one solution preparation cycle. Only after both the water tank 210 and the material tank have completed the required number of water / material-pouring actions for one solution preparation cycle will the next solution preparation cycle begin, thereby achieving the purpose of adjusting the concentration of the spray solution.

[0050] Furthermore, when the level of the mixing liquid in the mixing tank 120 exceeds the level controlled by the jog switch 640 of a certain level control device, the level plate 610 rises, driving the synchronizing rod 620 to move, causing the jog switch 640 of the level control device to close, the water supply pipe 410 and the pulley 520 to stop working, and the mixing tank 120 continues to work until the level of the mixing liquid in the mixing tank 120 is lower than the fixed level, at which point the water supply pipe 410 and the pulley 520 continue to work.

[0051] This invention can be installed on mechanical devices that generate dust during operation in a mine to prepare dust removal solutions on-site. These mechanical devices can be rock dumpers or crushers, etc. The concentration of the prepared spray solution can be adjusted by adjusting the weights of the first and second weight adjustment frames and the number of counts by the first counter 440 and the second counter 560 within one solution preparation cycle.

[0052] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
