Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic systems, and particularly to an emulsion liquid tank for a mine roadway and a control method thereof. Background Art

[0002] In the prior art, an integrated liquid supply system underground in coal mines is a key device in a fully mechanized coal mining face. The emulsion liquid pump station in the integrated liquid supply system provides a power source for hydraulic supports. Among them, the emulsion liquid tank is an auxiliary device of the integrated liquid supply system, which is used to store emulsion liquid and supply emulsion liquid to the emulsion liquid pump station.

[0003] Due to the limited height of the fully mechanized coal mining face and the width of the equipment transport train, the emulsion liquid tank is generally designed in a slender structure to facilitate the transportation of the emulsion liquid tank in the fully mechanized coal mining face. The fully mechanized coal mining face is driven along the extension direction of the strata structure and usually has large undulations with a certain slope.

[0004] Since the pipeline pump is only arranged at one end of the oil liquid storage tank. When the oil liquid storage tank is on an inclined plane, the emulsion liquid in the oil liquid storage tank will deviate from one end of the oil liquid storage tank as the liquid level drops. This causes that when the end where the pipeline pump is located is at a high position, the pipeline pump cannot suck the emulsion liquid below its liquid inlet pipe, and the emulsion liquid in the oil liquid storage tank cannot be fully utilized, thus the emulsion liquid cannot be stably supplied to the emulsion liquid pump station, greatly reducing the working efficiency.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0030] In the embodiments of the present invention, an emulsion liquid tank for a mine roadway is introduced.

[0031] As Figure 1 and Figure 2 shown, the emulsion liquid tank mainly includes a base, an oil liquid storage 100, and a pipeline pump 200. The oil liquid storage 100 is fixed above the base by welding. The pipeline pump 200 is arranged at one end in the length direction of the oil liquid storage 100. And, the liquid inlet pipe 210 of the pipeline pump 200 is installed on the end face of the oil liquid storage 100.

[0032] Specifically, an interface for mating connection with the liquid inlet pipe 210 is provided on the end face of the oil liquid storage 100. The liquid inlet pipe 210 is in communication with the accommodation cavity 110 of the oil liquid storage 100 through the interface.

[0033] In order to adapt to the height of the fully mechanized coal mining face and the width of the equipment transportation train for easy transportation. The box body of the oil liquid storage 100 is set to a slender structure, so as to ensure that the accommodation cavity 110 of the oil liquid storage 100 can hold an enough capacity of emulsion liquid. Among them, the box body of the oil liquid storage 100 is made by welding steel plates. The length of the box body is several times its width or its height.

[0034] However, since the fully mechanized coal mining face is driven along the extension direction of the strata structure, it usually has undulations with a large slope. For example, Figure 4 and Figure 5 As shown, when the oil storage tank 100 is on an inclined plane, the emulsion in the oil storage tank 100 will deviate from one end of the oil storage tank 100 as the liquid level drops. This causes the end with the pipeline pump 200 to be at a high position, and the pipeline pump 200 cannot suck the emulsion.

[0035] Therefore, a guiding pipe 300 and a pulling mechanism 400 are arranged in the accommodating cavity 110. The outlet end 320 of the guiding pipe 300 is communicated with the liquid inlet pipe 210. The inlet end 310 of the guiding pipe 300 is connected to the pulling mechanism 400. Thus, when the heights of the two ends of the oil storage tank 100 are different, the pulling mechanism 400 drives the inlet end 310 to move towards the end of the accommodating cavity 110 at the lower position.

[0036] In this embodiment, by arranging the pulling mechanism 400 to drive the guiding pipe 300, the inlet end 310 of the guiding pipe 300 can move correspondingly to the bottom of the emulsion along with the change of the height positions of the two ends of the oil storage tank 100, ensuring that the emulsion can be stably transported before the emulsion is exhausted when the emulsion tank is on an inclined ground, avoiding the phenomenon that the emulsion cannot be normally transported when the emulsion deviates from one end of the oil storage tank 100, and enabling the emulsion tank to be applicable to the working face with a large slope.

[0037] On the basis of the above embodiment, in another embodiment of the present invention, an emulsion tank for a mine roadway is introduced.

[0038] As Figure 1 and Figure 2 shown, the pulling mechanism 400 includes a rotating assembly 410 and a traction member 420. Among them, the rotating assembly 410 is installed on the side wall of the oil storage tank 100. The traction member 420 is in transmission connection with the rotating assembly 410.

[0039] The two rotating assemblies 410 are respectively arranged at the two ends of the accommodating cavity 110. And the two rotating assemblies 410 tension the traction member 420 along the length direction of the accommodating cavity 110. The inlet end 310 is connected to the traction member 420.

[0040] Thus, when the rotating assembly 410 rotates clockwise or counterclockwise, the traction member 420 can drive the inlet end 310 of the guiding pipe 300 to reciprocate between the two ends of the accommodating cavity 110 along the length direction of the accommodating cavity 110.

[0041] Further, the rotating assembly 410 is set as a motor and a sprocket. The transmission member is set as a chain. The sprocket is sleeved on the output shaft of the motor. The chain is in transmission connection with the sprocket. By controlling the operation of the motor to drive the sprocket to rotate, the chain moves circumferentially along the length direction of the accommodating cavity 110.

[0042] Further, the rotating assembly 410 can also be set as a motor and a pulley. The corresponding transmission member is set as a belt.

[0043] Preferably, the rotating assembly 410 further includes a rotating shaft. The sprocket or the pulley is sleeved on the rotating shaft. The motor is connected to the rotating shaft, so as to drive the sprocket or the pulley to rotate through the rotating shaft. In this way, a plurality of guiding tubes 300 can be arranged in the accommodating cavity 110, and by sleeving a plurality of synchronously rotating sprockets or pulleys on the rotating shaft, the inlet end 310 of the guiding tube 300 is driven to move in the accommodating cavity 110.

[0044] On the basis of the above embodiments, in another embodiment of the present invention, an emulsion liquid tank for a mine roadway is introduced.

[0045] Generally, the guiding tube 300 is set as a flexible hose. And the length of the guiding tube 300 is set to be greater than the length of the accommodating cavity 110, so that the inlet end 310 of the guiding tube 300 can be moved to any position in the accommodating cavity 110 to meet the requirement of stably sucking the emulsion liquid.

[0046] However, during actual use, when the inlet end 310 of the guiding tube 300 is driven to be close to its outlet end 320, the guiding tube 300 is prone to be bent. At this time, the tube walls of the guiding tube 300 are squeezed together, greatly reducing the flow rate of the emulsion liquid, and even blocking the guiding tube 300.

[0047] To avoid the guiding tube 300 from being bent during the operation of the equipment, a telescopic structure 330 is arranged on the tube wall of the guiding tube 300.

[0048] Specifically, the guiding tube 300 includes an inlet end 310, an outlet end 320 and a telescopic structure 330. The telescopic structure 330 is located between the inlet end 310 and the outlet end 320, and is used to adaptively adjust the length of the guiding tube 300 along with the reciprocating movement of its inlet end 310 in the accommodating cavity 110.

[0049] Among them, the telescopic structure 330 can be composed of a plurality of short tubes with different diameters and capable of sliding relative to each other along the central axis direction and overlapping and sleeving. When the pulling mechanism 400 drives the inlet end 310 to move along the length direction of the accommodating cavity 110, any short tube can slide out or retract from the adjacent short tube along the central axis direction.

[0050] Furthermore, the telescopic structure 330 can also be set as a corrugated pipe wall formed by folding along the radial direction. When the pulling mechanism 400 drives the inlet end 310 to move along the length direction of the accommodating cavity 110, the corrugated pipe wall can be unfolded or folded along with the movement of the inlet end 310, so as to adaptively adjust the length of the guiding pipe 300.

[0051] Based on the above embodiments, in another embodiment of the present invention, an emulsion liquid tank for a mine roadway is introduced.

[0052] In order to enable the pipeline pump 200 to cooperate with the pulling mechanism 400 for operation, the emulsion liquid tank is further provided with a controller 500 installed on the pipeline pump 200. The controller 500 is electrically connected to the pipeline pump 200 and the pulling mechanism 400 respectively.

[0053] When using the emulsion liquid tank to supply liquid to the hydraulic support in the fully mechanized coal mining face, the controller 500 first starts the pulling mechanism 400 to move the inlet end 310 to the lower part of the accommodating cavity 110, and then starts the pipeline pump 200 to pump the emulsion liquid in the accommodating cavity 110.

[0054] In this embodiment, the controller 500 can control the sequential operation of the pulling mechanism 400 and the pipeline pump 200, so that the inlet end 310 of the guiding pipe 300 always sucks the emulsion liquid from the lowest position, ensuring that the emulsion liquid can be stably transported when the emulsion liquid tank is on an inclined ground.

[0055] Based on the above embodiments, in another embodiment of the present invention, an emulsion liquid tank for a mine roadway is introduced.

[0056] A liquid level sensor 600 for monitoring the liquid level height is arranged in the oil liquid storage 100. One liquid level sensor 600 is arranged at each of the two end faces in the length direction of the accommodating cavity 110.

[0057] The controller 500 is electrically connected to the liquid level sensor 600 for receiving the liquid level signal and judging the height of the two ends of the accommodating cavity 110.

[0058] As Figure 4 and Figure 5 shown, the controller 500 obtains a first height value of the end face of the accommodating cavity 110 close to the pipeline pump 200 below the emulsion liquid level through the left liquid level sensor 600. The controller 500 obtains a second height value of the end face of the accommodating cavity 110 far from the pipeline pump 200 below the emulsion liquid level through the right liquid level sensor 600.

[0059] By comparing the magnitudes of the first height value and the second height value, it is possible to determine the lower end of the oil liquid storage tank 100, and then control the pulling mechanism 400 to drive the inlet end 310 to move towards the lower end of the accommodation cavity 110. Obviously, when the oil liquid storage tank 100 is placed on an inclined ground, the larger the height value, the greater the depth of the emulsion, that is, the end with the larger height value is at the lower position.

[0060] Based on the above embodiments, in another embodiment of the present invention, an emulsion tank for a mine roadway is introduced.

[0061] Among them, two pipeline pumps 200 are configured, one for standby, to ensure that the emulsion tank can operate continuously without interruption. When one pipeline pump 200 is damaged, another pipeline pump 200 can be immediately switched to operate, which not only improves the reliability but also can improve the efficiency of coal mining work.

[0062] Specifically, as Figure 3 shown, the two pipeline pumps 200 are arranged at the same end of the oil liquid storage tank 100. Two corresponding guiding pipes 300 are arranged in the accommodation cavity 110. The two guiding pipes 300 are arranged in parallel at intervals. And, the two guiding pipes 300 connect their respective inlet ends 310 to the pulling mechanism 400.

[0063] Furthermore, a butterfly valve 800 is further included, which is arranged between the liquid inlet pipe 210 and the oil liquid storage tank 100, and is used to cut off the connection state between the pipeline pump 200 and the accommodation cavity 110.

[0064] The butterfly valve 800 is used to cut off the connection between the pipeline pump 200 and the oil liquid storage tank 100, and its main functions are as follows: 1. When both butterfly valves 800 are closed, it can be used for replacing and repairing the damaged pipeline pump 200; 2. By opening the butterfly valve 800 connected to the working liquid tank pipeline pump 200 and closing the other butterfly valve 800, the effect of one for standby can be ensured for the pipeline pump 200.

[0065] Based on the above embodiments, in another embodiment of the present invention, an emulsion tank for a mine roadway is introduced.

[0066] Existing emulsion tanks do not have an alarm device. During use, when the pipeline pump 200 sucks air, there is no alarm device to remind the operator, and the pipeline pump 200 will continue to operate in the air-sucking state, resulting in damage to the pipeline pump 200.

[0067] Therefore, a water pressure sensor 700 is provided on the liquid outlet pipe 220 of the pipeline pump 200. The controller 500 is electrically connected to the water pressure sensor 700 and is used to obtain a water pressure signal. When the water pressure is less than the set value, the controller 500 can control the pipeline pump 200 to stop running, avoiding damage to the pipeline pump 200.

[0068] On the basis of the above embodiments, in another embodiment of the present invention, a control method for an emulsion tank is introduced.

[0069] Among them, the emulsion tank further includes a controller 500. The controller 500 is electrically connected to the pipeline pump 200 and the pulling mechanism 400 respectively. When the emulsion tank is used to supply liquid to the hydraulic support in the fully mechanized coal mining face, the controller 500 first starts the pulling mechanism 400 to move the inlet end 310 to the lower part of the accommodating cavity 110, and then starts the pipeline pump 200 to pump the emulsion in the accommodating cavity 110.

[0070] A liquid level sensor 600 electrically connected to the controller 500 is provided at both ends of the accommodating cavity 110, which is used to receive a liquid level signal and judge the height of both ends of the accommodating cavity 110.

[0071] The control method is applied to the emulsion tank in any of the above embodiments, and the steps are as follows: S1. Obtain the height values of the end faces at both ends of the accommodating cavity 110 below the liquid level; S2. Compare the magnitudes of the height values, and control the inlet end 310 to move towards the end with the larger height value; S3. Control the pipeline pump 200 to run.

[0072] Specifically, as Figure 4 and Figure 5 shown, the controller 500 obtains the first height value of the end face of the accommodating cavity 110 close to the pipeline pump 200 below the emulsion liquid level through the liquid level sensor 600 on the left side. The controller 500 obtains the second height value of the end face of the accommodating cavity 110 far from the pipeline pump 200 below the emulsion liquid level through the liquid level sensor 600 on the right side.

[0073] By comparing the magnitudes of the first height value and the second height value, it is possible to determine the end of the oil storage tank 100 at the lower position, and then control the pulling mechanism 400 to drive the inlet end 310 to move towards the end with the larger height value. After that, control the pipeline pump 200 to start.

[0074] When the emulsion tank is used in the fully mechanized mining face, the oil storage tank 100 mainly has three states: 1. The oil storage tank 100 is on a horizontal working face; 2. The end of the oil storage tank 100 where the pipeline pump 200 is provided is at a high position, as Figure 4As shown in; 3. One end of the pipeline pump 200 in the oil storage tank 100 is at a lower position, such as Figure 5 shown.

[0075] Correspondingly, when the oil storage tank 100 is on a horizontal working surface, the liquid level sensors 600 at both ends of the accommodation cavity 110 can detect the liquid level. And the detected liquid level height values are equal.

[0076] At this time, the controller 500 can normally control the start and stop of the pipeline pump 200. When the pipeline pump 200 is working, the water pressure sensor 700 can detect the water pressure output by the pipeline pump 200. If the liquid level sensors 600 at both ends of the accommodation cavity 110 cannot detect the liquid level, it indicates that the emulsion in the oil storage tank 100 is exhausted. The controller 500 controls the pipeline pump 200 to stop working. When the liquid level is replenished to a position above the liquid level sensor 600, the controller 500 can control the liquid tank pipeline pump 200 to start working.

[0077] Furthermore, when one end of the pipeline pump 200 in the oil storage tank 100 is at a higher position, the liquid level sensor 600 near the pipeline pump 200 cannot detect the liquid level, and the liquid level sensor 600 at the end far from the pipeline pump 200 can detect the liquid level. At this time, the controller 500 controls the pulling mechanism 400 to drive the inlet end 310 of the guiding pipe 300 to move to the end far from the pipeline pump 200. Then, it controls the pipeline pump 200 to start. At this time, the water pressure sensor 700 can detect the output water pressure of the pipeline pump 200.

[0078] If the liquid level sensors 600 at both ends of the accommodation cavity 110 cannot detect the liquid level, it means that the emulsion in the oil storage tank 100 is exhausted. Control to close the pipeline pump 200 and give an alarm to prompt the replenishment of the emulsion. If the liquid level sensors 600 at both ends of the accommodation cavity 110 can detect the liquid level, it means that the emulsion in the oil storage tank 100 is relatively full. The inlet end 310 of the guiding pipe 300 is below the emulsion liquid level, and the controller 500 can directly start the pipeline pump 200 without controlling the adjustment of the guiding pipe 300.

[0079] Furthermore, when one end of the pipeline pump 200 in the oil storage tank 100 is at a lower position, the liquid level sensor 600 near the pipeline pump 200 can detect the liquid level, and the liquid level sensor 600 at the end far from the pipeline pump 200 cannot detect the liquid level. At this time, the controller 500 controls the pulling mechanism 400 to drive the inlet end 310 of the guiding pipe 300 to move to the end near the pipeline pump 200. Then, it controls the pipeline pump 200 to start. At this time, the water pressure sensor 700 can detect the output water pressure of the pipeline pump 200.

[0080] In this embodiment, by arranging a liquid level sensor 600 and a water pressure sensor 700 in the emulsion tank and adopting the above control method, the liquid level of the emulsion in the oil storage tank 100 can be automatically detected, which improves the automation level of the equipment, can improve the working efficiency of the fully mechanized coal mining face, and meets the requirements of coal mining enterprises.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

[0082] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
