Description

Technical Field

[0001] The invention relates to the technical field of filling pumps, and in particular to a filling device for mining. Background Art

[0002] In various industrial fields, when materials need to be pumped to a farther or higher position, a filling device is required. In mining, this device can transport filling materials such as tailings and cement to the goaf for filling; it usually includes a hopper, two piston pumps and an S valve. When the piston pump is working, the reciprocating motion of the piston forms negative and positive pressures in the pump body, thereby achieving the suction and discharge of concrete. By setting a swinging S valve, one of its active ends is alternately connected to the two piston pumps, so that when one piston pump sucks concrete, the other piston pump discharges concrete. When the concrete is discharged from the piston pump, it passes through the discharge pipe to the target position, thereby achieving the pumping work.

[0003] However, the filling device in the prior art will disturb the concrete in the hopper when driving the S-valve to swing. When the S-valve swings at a high frequency, the S-valve will be subject to the resistance of the material and will not be able to reach the switching position in time. As a result, when the piston pump pumps out concrete, it will cause discontinuous and uneven pumping of materials, affecting the filling effect and efficiency. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention proposes a filling device for mining, which solves the problem in the prior art that the S valve is subject to resistance from materials when swinging and cannot reach the switching position in time, as well as the problem that the filling effect and efficiency are affected.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] like Figures 1 to 9 As shown, a filling device for mining provided by an embodiment of the present invention includes a base 100, a fixed shell 200, a movable shell 300, a power assembly 400, a driving mechanism 500 and a control system.

[0044] The base 100 is detachably fixedly connected with a hopper 110 and a water tank 120. The water tank 120 is used to meet the water demand during the filling process and maintain the stable operation of the system. The hopper 110 is filled with concrete; a pumping pipe 111 is fixedly connected to one side of the hopper 110. The pumping pipe 111 extends along a first direction and is connected to the hopper 110;

[0045] Two fixed shells 200 are arranged at intervals along the second direction, and the second direction is perpendicular to the first direction; the fixed shells 200 are fixedly installed in the hopper 110;

[0046] The power assembly 400 includes a first piston pump 410, a second piston pump 420, a first tube 430 and a second tube 440; the first piston pump 410 and the second piston pump 420 are arranged at one side of the hopper 110 at intervals, and both extend along the first direction, and one end of the first piston pump 410 and the second piston pump 420 facing the hopper 110 is fixedly connected to one end of the hopper 110 away from the pumping tube 111, and the first piston pump 410 and the second piston pump 420 are in communication with the hopper 110;

[0047] The first tube 430 and the second tube 440 both include a fixed tube 431 and a movable tube 432, and both the fixed tube 431 and the movable tube 432 are right-angled bend tubes; the first tube 430 is connected to the first piston pump 410, and the second tube 440 is connected to the second piston pump 420; the two fixed tubes 431 are both arranged horizontally and fixedly connected to the fixed shell 200, one end of the two fixed tubes 431 is respectively fixedly connected to the first piston pump 410 and the second piston pump 420 one end facing the hopper 110, and the other end is coaxial with the movable shell 300 and extends toward the movable shell 300; the two movable tubes 432 are fixedly connected to the movable shell 300, and the inflection points of the two movable tubes 432 are abutted and cross-shaped; one end of the two movable tubes 432 is respectively rotatably connected to the two fixed tubes 431, and the other end extends outward along the radial direction of the movable shell 300; the movable tube 432 is rotatably connected to the fixed tube 431 through the clamping ring 450; the driving mechanism 500 is used to drive the movable shell 300 to rotate around its own axis;

[0048] The control system is used to control the operation of the driving mechanism 500 , the first piston pump 410 and the second piston pump 420 .

[0049] During filling, concrete is filled into the hopper 110; the driving mechanism 500 is started through the control system, and the driving mechanism 500 drives the movable shell 300 to rotate around its own axis. When the movable shell 300 rotates, it drives the two movable pipes 432 to rotate synchronously. During the rotation process, the two movable pipes 432 are alternately connected to the pump pipe 111.

[0050] When the movable tube 432 of the first tube 430 is connected to the hopper 110, the control system puts the first piston pump 410 in a liquid suction state, and the pump cavity gradually increases, so that the concrete in the hopper 110 enters the pump cavity of the first piston pump 410 through the movable tube 432 and the fixed tube 431 in sequence, and the second piston pump 420 is in a liquid discharge state; as the movable housing 300 rotates, the movable tube 432 of the first tube 430 is connected to the pumping pipe 111, and the first piston pump 410 and the second piston pump 420 are switched through the control system. The first piston pump 410 is in a discharging state, and the pump chamber gradually decreases, so that the concrete in the pump chamber is pumped out from the pumping pipe 111 through the fixed pipe 431 and the movable pipe 432 in sequence for filling; while the first piston pump 410 is discharging, the second piston pump 420 is in a suction state, and the concrete in the hopper 110 is drawn into the pump chamber of the second piston pump 420. Thereafter, the movable housing 300 continues to rotate, and the first pipe 430 and the second pipe 440 are alternately connected to the pumping pipe 111, thereby completing the pumping work.

[0051] The present invention changes the S valve that reciprocates in the hopper 110 in the prior art into a movable shell 300 that continuously rotates in one direction and a first tube 430 and a second tube 440 arranged inside the shell, thereby reducing the friction resistance between the concrete and the shell when switching the connection state, solving the problem in the prior art that the large resistance of the concrete during switching causes the switching to fail to be in place and affects the pumping of materials, thereby ensuring the filling quality and filling efficiency.

[0052] In a further embodiment, a material storage shell 310 is provided outside the movable shell 300, and the two ends of the material storage shell 310 in the second direction are respectively fixedly connected to the two fixed shells 200; the material storage shell 310 is located on the side of the movable shell 300 facing the pumping pipe 111; the material storage shell 310 and the movable shell 300 define a material storage cavity 311, and the material storage cavity 311 is connected to a transition pipe 312, and the transition pipe 312 is connected to the pumping pipe 111.

[0053] When the movable tube 432 of the first tube 430 is connected to the hopper 110, the control system puts the first piston pump 410 in a liquid suction state, and the pump chamber gradually increases, so that the concrete in the hopper 110 is sucked into the pump chamber of the first piston pump 410. As the movable shell 300 rotates, the movable tube 432 of the first tube 430 rotates to the storage chamber 311, and the first piston pump 410 and the second piston pump 420 are switched through the control system. At this time, the first piston pump 410 is in a liquid discharge state, and the pump chamber gradually decreases, thereby discharging the concrete in the pump chamber into the storage chamber 311. When the storage chamber 311 is filled with concrete, the concrete in the storage chamber 311 enters the pump pipe 111 through the transition pipe 312 under the action of pressure to carry out the filling work.

[0054] When the first piston pump 410 is in a discharging state, the second piston pump 420 is in a sucking state, and the concrete in the hopper 110 is pumped into the pump chamber of the second piston pump 420; at the same time, the movable shell 300 is continuously rotated under the drive of the driving mechanism 500, and the first piston pump 410 and the second piston pump 420 continuously inject concrete into the storage chamber 311, and then continuously pump material through the transition pipe 312 and the pumping pipe 111 to complete the filling.

[0055] Since the projection of the storage chamber 311 on the plane perpendicular to the first direction is fan-shaped, the concrete in the first piston pump 410 and the second piston pump 420 can be discharged continuously, rather than only when facing the pump pipe 111. Therefore, the movable shell 300 rotates continuously without braking, which solves the problem of damage to the device parts when the S valve switches to the connected state due to the large braking torque of the filling device in the prior art, thereby extending the service life of the filling device.

[0056] In a further embodiment, the projection of the storage cavity 311 on a plane perpendicular to the first direction is fan-shaped, and the corresponding central angle is greater than 180°.

[0057] Reference Figure 8 When the movable tube 432 of the first tube 430 is connected to the material storage chamber 311, the first piston pump 410 is in a liquid discharge state, and the second piston pump 420 is in a liquid suction state. As the movable housing 300 rotates, the movable housing 300 rotates to Fig. 9 state, the first tube 430 and the second tube 440 are connected to the storage chamber 311 at the same time, and the two are in a discharge state through the control system. When the movable shell 300 continues to rotate at a preset angle, the first tube 430 leaves the storage chamber 311 and is connected to the hopper 110. At this time, the second tube 440 is still connected to the storage chamber 311, the first piston pump 410 is in a suction state, and the second piston pump 420 is in a discharge state. By making the central angle of the projection of the storage chamber 311 on the plane perpendicular to the first direction greater than 180°, it is ensured that the positive pressure state is continuously maintained in the storage chamber 311, and concrete is continuously output to the transition pipe 312 and the pumping pipe 111, which solves the backflow problem of the filling device in the prior art when switching the S-valve connection state, and further improves the filling efficiency.

[0058] In a further embodiment, the pumping speed of the first piston pump 410 and the second piston pump 420 is greater than the discharging speed, so as to ensure that the first pipe 430 and the second pipe 440, when connected with the hopper 110, suck in enough concrete to ensure that the first pipe 430 and the second pipe 440, when connected with the material storage chamber 311, continuously discharge concrete into the material storage chamber 311, thereby avoiding intermittent discharge, preventing air from entering the material storage chamber 311, and preventing the filling effect from being affected by uneven discharge.

[0059] In a further embodiment, the two ends of the storage chamber 311 along the circumferential direction of the movable shell 300 are respectively set as a first end and a second end, the first end is located below the second end, and the rotation direction of the movable shell 300 is set so that the movable tube 432 enters the storage chamber 311 from the first end and leaves the storage chamber 311 from the second end.

[0060] When any one of the movable tubes 432 leaves the material storage chamber 311 from the second end, as the movable shell 300 rotates, the concrete in the hopper 110 is sucked from top to bottom. Even in the case where the slump of the concrete is small, after the concrete in the hopper 110 is sucked, the concrete located above has sufficient time to collapse and flow downward. When the other movable tube 432 leaves the discharge chamber from the second end, the position in the hopper 110 that is sucked has been filled with concrete, thereby ensuring that the concrete entering the first piston pump 410 or the second piston pump 420 is in a uniform state. This solves the problem in the prior art that when the filling device sucks concrete with a small slump, after the concrete at the position of the suction port is sucked, the concrete above it has not yet filled the position, but the suction process continues, causing gas to enter the first piston pump 410 or the second piston pump 420, further ensuring the filling effect and filling efficiency.

[0061] In a further embodiment, the driving mechanism 500 includes a rotating motor 510, a rotating shaft 520, a gear 530 and a ring gear 540; the rotating motor 510 is fixedly connected to the base 100; one end of the rotating shaft 520 is synchronously rotatably connected to the output shaft of the rotating motor 510, and the other end passes through the fixed shell 200 and is synchronously rotatably connected to the gear 530; the ring gear 540 is fixedly connected inside the movable shell 300, and the ring gear 540 is meshed with the gear 530 for transmission.

[0062] When filling is required, the driving motor is started, and the driving motor drives the rotating shaft 520 to rotate synchronously, and the rotating shaft 520 drives the gear 530 to rotate synchronously. When the gear 530 rotates, it drives the ring gear 540 to rotate, and then drives the rotating shell to rotate synchronously. When the rotating shell rotates, it drives the two movable pipes 432 to rotate synchronously, and cooperates with the alternating operation of the first piston pump 410 and the second piston pump 420 to pump the concrete in the hopper 110 into the pumping pipe 111.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
