Description

Technical Field

[0001] This invention belongs to the field of mining equipment technology, specifically a mining two-stage pump that is easy to fix and easy to move. Background Technology

[0002] Traditional pumps operate as follows: the pump casing is filled with the liquid to be pumped; after startup, the impeller rotates at high speed driven by the shaft, and the liquid between the blades must also rotate. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller at high speed and entering the volute pump casing. In the volute casing, the liquid decelerates due to the gradual expansion of the flow channel, converting some of its kinetic energy into static pressure energy, and finally flows into the discharge pipe at a higher pressure, delivering it to the required location. As the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed at the center of the impeller. Because the pressure above the liquid surface in the reservoir is greater than the pressure at the pump inlet, the liquid is continuously forced into the impeller. Therefore, as long as the impeller continues to rotate, the liquid will be continuously drawn in and discharged.

[0003] This pump body structure is extremely efficient; however, the high-speed rotation of the impeller makes it very easy for fine sand inside to accumulate and damage the impeller. For current mining applications, the water contains a lot of impurities, and large and small stones can easily clog the inlet screen, making traditional pump bodies unsuitable for mining conditions.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This easily fixed and easily movable mining two-stage pump, through the configuration of transmission gears, slide rods, sliding parts, sliding holes, water-cooling cylinders, connecting rods, and airtight cylinders, operates by rotating two transmission gears, which in turn drive the same slide rod in a circular trajectory. Simultaneously, the slide rod slides through a sliding hole in the inner wall of the sliding part, maintaining the reciprocating motion of the sliding part in two directions. This causes the sliding part to drive the two airtight cylinders in synchronous motion. As the airtight cylinders slide, they correspondingly control the pressure changes inside the water-cooling cylinders. When the airtight cylinder approaches the sealing plug, the one-way valve remains closed with the sealing plug. When the internal pressure increases, the water is discharged through the one-way manifold until the airtight cylinder moves a certain distance, pressing the pusher and causing it to slide out of the plug and squeeze the end of the water-cooling cylinder outward. When the airtight cylinder moves away from the plug, a negative pressure is formed inside the water-cooling cylinder, causing the water to return to its original position when it enters. At the same time, the one-way valve plate bends, allowing external water to enter. This method can maintain uninterrupted water transmission when the two airtight cylinders reciprocate in bipolar motion, and it avoids damage due to the absence of an impeller structure. It can also push out the water inlet to prevent the accumulation of impurities.

[0020] 2. This easily fixed and easily movable mining two-stage pump, by setting up an electromagnet, rotor, sun gear, planetary gears, internal gear ring, and external gear cover, operates as follows: when the electromagnet is activated, the rotor is energized and begins to rotate, causing the two sun gears to rotate. Subsequently, as the sun gears rotate at high speed, they drive several planetary gears on their surface to mesh with the inner wall of the internal gear ring and begin to move. The internal gear ring is fixed by a base, and when the planetary gears move, they drive the external gear cover to slide on the surface of the internal gear ring, thus completing the deceleration drive of the transmission gears by the external gear cover. This ensures that the airtight cylinder has sufficient pressure and suction to maintain its stable and uniform speed movement.

[0021] 3. This easily fixed and easily movable mining two-stage pump, equipped with a drive gear, driven gear, impeller, diversion shroud, rotary sealing ring, outlet, and inlet, discharges wastewater through a one-way manifold and hose in conjunction with an airtight cylinder during operation. The drive gear rotates synchronously with the outer gear cover, meshing with the driven gear to drive the impeller to rotate at high speed on the inner wall of the rotary sealing ring. As the impeller rotates, the suction force in the middle, combined with the diversion shroud, draws clean water in through the inlet and discharges it through the outlet. This method enables the discharge of wastewater from the mine while simultaneously drawing in or out clean water. This two-stage pump design is better suited for mining applications.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1 to 8The present invention provides a technical solution: a mine two-stage pump that is easy to fix and easy to move, comprising a sealed outer shell composed of a lower shell 1 and an upper shell 2. Two supports 3 are fixedly installed on the inner wall of the lower shell 1. A water supply mechanism 4 is fixedly installed through the surface of the support 3. A reciprocating sliding member 11 is installed on the opposite surface of the two water supply mechanisms 4. A sliding rod 10 slides through the inner wall of the sliding member 11.

[0034] Both ends of the slide bar 10 are fixed with transmission gears 7, and both transmission gears 7 are meshed with reduction mechanisms 6. The two reduction mechanisms 6 are connected to a drive mechanism 5 on opposite sides. The drive mechanism 5 is installed on the surface of the two brackets 3. The two water supply mechanisms 4 are connected to a one-way manifold 8. A hose 9 is provided at the top of the one-way manifold 8.

[0035] In use, as the electromagnet 52 is activated, the rotor 54 is energized and begins to rotate, causing the rotor 54 to drive the two sun gears 61 to rotate. As the sun gears 61 rotate at high speed, they drive several planetary gears 62 on their surface to mesh with the inner wall of the internal gear ring 63 and begin to move. The internal gear ring 63 is fixed by the base 65. When the planetary gears 62 move, they cause the outer gear cover 64 to slide on the surface of the internal gear ring 63, thus completing the deceleration drive of the outer gear cover 64 on the transmission gear 7. This ensures that the airtight cylinder 42 maintains sufficient pressure and suction to maintain its stable and uniform movement.

[0036] When the two transmission gears 7 rotate, they drive the same slide rod 10 to move in a circular trajectory. Simultaneously, the slide rod 10 slides through the sliding hole 12 on the inner wall of the slide member 11, maintaining the slide member 11 in reciprocating motion in two directions. This causes the slide member 11 to drive the two airtight cylinders 42 to move synchronously. As the airtight cylinders 42 slide, they correspondingly control the pressure change inside the water-cooling cylinder 41. When the airtight cylinder 42 approaches the seal 44, the one-way valve 45 remains closed with the seal 44, and... When the internal pressure increases, the water is discharged through the one-way manifold 8 until the airtight cylinder 42 moves to a certain distance, causing it to press the pusher 43, which slides out of the plug 44 and squeezes the end of the water-cooling cylinder 41 outward. When the airtight cylinder 42 moves away from the plug 44, a negative pressure is formed inside the water-cooling cylinder 41, so that when water flows in, it is reset by the water flow. At the same time, the one-way valve plate 45 bends, allowing external water to enter. With the cooperation of the two airtight cylinders 42, the hose 9 keeps transmitting water continuously.

[0037] Example 2

[0038] Basically the same as Example 1, but with a further improvement:

[0039] A drive gear 13 is rotatably driven through the upper surface of the inner wall of the lower casing 1. The drive gear 13 is connected to the reduction mechanism 6 located above. A driven gear 14, rotatably connected to the inner wall of the upper casing 2, meshes with the surface of the drive gear 13. A wheel 15 is fixed to the upper surface of the driven gear 14, and a rotating sealing ring 16 is rotatably sealed on the surface of the wheel 15. A flow guide hood 17 is fixedly connected to the inner wall of the rotating sealing ring 16. An inlet 18 penetrating the surface of the upper casing 2 is snapped into the inner wall of the flow guide hood 17. An outlet 19 is snapped into the arc-shaped side wall of the rotating sealing ring 16, and the two ends of the outlet 19 are respectively connected to the rotating sealing ring 16 and the upper surface of the upper casing.

[0040] With the cooperation of the airtight cylinder 42, the sewage is discharged through the one-way manifold 8 and the hose 9. The synchronous drive gear 13 rotates synchronously with the outer gear cover 64. The drive gear 13 meshes with the driven gear 14 to drive the wheel 15 to rotate at high speed on the inner wall of the rotating sealing ring 16. When the wheel 15 rotates, with the cooperation of the diversion cover 17, the suction force in the middle draws clean water into the inlet 18 and then discharges it through the outlet 19, realizing the discharge of sewage inside the mine and the simultaneous operation of drawing in or out clean water.

[0041] Specifically, such as Figure 3 As shown: The water supply mechanism 4 includes a water-cooling cylinder 41 fixed to the surface of the bracket 3. A plug 44 is fixedly connected to the inner wall of the water-cooling cylinder 41. An airtight cylinder 42 is slidably connected to the inner wall of the water-cooling cylinder 41. A pusher 43 is fixedly fixed through the surface of the plug 44. A one-way valve plate 45 with a medium-thick edge and thin edge is installed on one side of the plug 44. Several screen holes for blocking impurities are opened through the surfaces of the plug 44 and the pusher 43. A sliding hole 12 for the sliding rod 10 to slide back and forth is opened on the surface of the sliding member 11. By setting the water-cooling cylinder 41, the water-cooling cylinder 41 maintains good internal sealing and protection, enabling it to cooperate with the airtight cylinder 42 and the plug 44 to pressurize and transmit sewage. By setting the plug 44, the plug 44 can protect the inlet 18 and filter impurities. At the same time, the one-way valve plate 45 on the surface can maintain the effect of one-way flow of water. By setting the recommendation, the pusher 43 is a workpiece that fits into the shape of one side of the plug 44 and whose screen hole position is consistent. One side of its pusher slides through the surface of the plug 44 in a rod shape, making small-amplitude movements, which can maintain stable movement within a certain range.

[0042] Specifically, such as Figure 6As shown, the drive mechanism 5 includes mounting members 53 fixed to two brackets 3. Electromagnets 52 are mounted on the surfaces of the two mounting members 53, and rotating rotors 54 are mounted on the inner walls of the electromagnets 52. A support frame 51 for rotating and fixing the rotor 54 and mounting the carbon brushes is jointly fixed to the surfaces of the two mounting members 53. By providing the mounting members 53, the mounting members 53 can maintain the mounting effect on the electromagnets 52 and the support frame 51. Together with the support frame 51, the entire drive mechanism 5 can maintain a stable supported and installed state.

[0043] Specifically, such as Figure 6 As shown: The reduction mechanism 6 includes a sun gear 61 fixed to one end of the rotor 54. Several planet gears 62 mesh with the surface of the sun gear 61. The tops of the planet gears 62 are rotatably connected to an outer gear cover 64. An inner gear ring 63, which slides against the inner wall of the outer gear cover 64, meshes with the surfaces of the planet gears 62. A base 65, used to fix the inner gear ring 63, is fixedly connected to the upper surface of the support frame 51. The outer gear cover 64 meshes with a corresponding transmission gear 7. By setting the sun gear 61, as the sun gear 61 drives the planet gears 62 to rotate, the planet gears 62, supported by the inner gear ring 63, maintain their rotation and drive the outer gear cover 64 to slide on the surface of the inner gear ring 63. This allows the airtight cylinder 42 to maintain stable, slow movement even when the rotational speed decreases, while simultaneously increasing the overall operating torque and transmission pressure, thus ensuring good transmission of impurities in the wastewater.

[0044] Specifically, such as Figure 1 As shown: The surface of the transmission gear 7 is rotatably mounted on the inner wall of the lower housing via a bearing. By setting up the lower housing, the lower housing and the upper housing can maintain a good overall protective effect.

[0045] Specifically, such as Figure 5 As shown: The one-way manifold 8 includes two sealed chambers 81, each connected to the inner wall of a corresponding airtight cylinder 42. The two sealed chambers 81 are connected to a three-way pipe 84. A one-way valve ball 82 slides along the inner wall of each sealed chamber 81, and a spring 83 is mounted on the surface of the one-way valve ball 82. By setting the sealed chambers 81, the two sealed chambers 81 can connect to the two airtight cylinders 42 respectively, and can move in coordination with the movement of the two airtight cylinders 42. When water enters, the water flow pushes open the one-way valve ball 82, causing it to press against the spring 83, allowing the sewage to flow. Subsequently, the one-way valve ball 82 remains sealed under the action of the spring 83, preventing the sewage inside the two airtight cylinders 42 from connecting and affecting the transmission effect. The sewage from the two sealed chambers 81 can then be discharged through the three-way pipe 84 and the flexible hose 9.
