Description

Technical Field

[0001] The present invention belongs to the technical field of mining equipment, and particularly relates to a jig with a flushing mechanism. Background Art

[0002] The diaphragm jig mainly generates pulsating water flow through the reciprocating motion of the diaphragm to separate minerals. In the diaphragm jig, the reciprocating motion of the diaphragm generates pulsating water flow, causing mineral particles to stratify according to density: large particles and high-density materials sink to the bottom, while light particles float on the upper layer.

[0003] The Chinese invention patent with the authorization announcement number CN113634359B discloses a self-circulating environmental protection diaphragm jig, including: a jig body, a reflux and reuse mechanism, a vibration screening mechanism, a purification and filtration mechanism, an adsorption and cleaning mechanism; a discharge port is connected to one side of the jig body; the reflux and reuse mechanism is arranged on the side of the discharge port away from the jig body and below the discharge port, and the reflux and reuse mechanism includes a reflux tank; the vibration screening mechanism is arranged in the reflux tank, and the vibration screening mechanism includes a screening mesh, and a fixed frame is arranged outside the screening mesh. By adding a corresponding screening and reflux mechanism to the diaphragm jig, the discharged water flow and materials can be sorted and recycled. In the above solution, when minerals are deposited on the surface of the diaphragm, some mineral particles are likely to remain in the gap between the diaphragm and the installation part. During the reciprocating motion of the diaphragm, the particles in the edge gap are likely to wear the surface of the diaphragm, affecting the overall service life. Summary of the Invention

[0004] The purpose of the present invention is to provide a jig with a flushing mechanism to solve the problem that some mineral particles are likely to remain in the gap between the diaphragm and the installation part, and the particles in the edge gap are likely to wear the surface of the diaphragm during the reciprocating motion of the diaphragm.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A jig with a flushing mechanism includes a base. A bunker is connected to the top of the base through a pillar. The bottom of the bunker is connected with a protective shell, and an installation seat is arranged in the inner cavity of the protective shell. A diaphragm main body is installed in the installation seat. A driving part is arranged on the top of the base. The diaphragm main body is driven by the driving part to drive the sampling medium in the bunker. A shielding mechanism is installed in the inner cavity of the installation seat to shield the gap between the diaphragm main body and the installation seat. The shielding mechanism includes a shielding pad, and a plurality of flushing guiding mechanisms are arranged on the periphery of the shielding pad to pump the flushing liquid out of the gap between the diaphragm main body and the installation seat for flushing.

[0007] As a further description of the above technical solution:

[0008] A fitting portion is integrally connected to the bottom of the shielding pad. The cross-sectional shape of the fitting portion is conical, and the conical end of the fitting portion is located radially inside the mounting seat. A receiving gap is formed between the conical surface of the fitting portion and the peripheral side of the inner cavity of the mounting seat.

[0009] As a further description of the above technical solution:

[0010] A plurality of receiving grooves are circumferentially formed along the axis on the peripheral side of the conical portion of the shielding pad. An excitation mechanism is provided in the receiving groove. The excitation mechanism includes an excitation block, and the excitation block is configured to jump along the axis direction of the shielding pad. The flushing liquid is ejected from the receiving gap by the movement of the jumping excitation block to flush the gap between the diaphragm body and the mounting seat.

[0011] As a further description of the above technical solution:

[0012] One side of the excitation block is connected to a fixing plate. Both sides of the top of the fixing plate are connected with telescopic rods. A supporting plate is connected between the other ends of the two telescopic rods. Both sides of the top of the supporting plate are connected with mounting members. The mounting members are connected to one side top of the inner cavity of the receiving groove. A spring is sleeved on the outer side wall of the telescopic rod, and both ends of the spring are respectively connected to corresponding positions on one side of the fixing plate and the supporting plate.

[0013] As a further description of the above technical solution:

[0014] The cross-sectional shape of the side of the excitation block close to the mounting seat is arc-shaped, and the side surface of the excitation block in contact with the receiving groove on the inner side has a conical surface. The flushing liquid contacts the conical surface of the excitation block through the flushing guiding mechanism to push the excitation block to move upward.

[0015] As a further description of the above technical solution:

[0016] The flushing guiding mechanism includes a receiving seat. The receiving seat is connected to one side of the inner cavity of the mounting seat. A plurality of liquid inlet holes are formed in the bottom of the receiving seat along the width direction. A guiding groove is connected to the bottom of the receiving seat. One side of the guiding groove is communicated with a fitting block. The liquid outlet at the top of the fitting block extends to one side of the shielding pad. A liquid injection ring is connected between the tops of the plurality of receiving seats, and the liquid injection ring is communicated with an external pumping mechanism through a pipeline.

[0017] As a further description of the above technical solution:

[0018] The cross-sectional shape of the fitting block is triangular, and the inclined surface at the top of the fitting block extends to the bottom of the shielding pad.

[0019] As a further description of the above technical solution:

[0020] The flushing guiding mechanism further includes a guiding pad. One side of the guiding pad is connected with a moving block. The moving block is slidably connected in a chute opened on the periphery of the shielding mechanism. The other side of the moving block is connected with a contraction part. The contraction part is connected to the inner cavity of the accommodating seat. The guiding pad is driven by water flow to drive the contraction part to contract, accelerating the flow of the flushing liquid in the inner cavity of the accommodating seat.

[0021] As a further description of the above technical solution:

[0022] The contraction part is a flexible membrane body, and the middle part of the flexible membrane body is connected to one side of the moving block.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In the present invention, through the designed shielding mechanism, when ore particles are deposited on the top side of the diaphragm main body, the shielding pads and the fitting parts located on the periphery can fully seal the device gap between the diaphragm main body and the mounting seat, which is beneficial to avoid the wear of the fine particles on the periphery of the diaphragm main body through the setting of the fitting parts. The bottom side of the fitting part can be injected and flushed through the flushing guiding mechanism. The flushing liquid can flush the fine particles from the side of the diaphragm main body to the axis position. Compared with the traditional diaphragm main body placed in the device, it is beneficial to improve the wear-resistant life of the periphery of the diaphragm main body.

[0025] 2. In the present invention, through the designed excitation mechanism, in order to avoid the accumulation of fine mineral particles when the shielding pad fitting part contacts the diaphragm main body, when the external pumping equipment sends the flushing liquid into the flushing guiding mechanism, the flushing mechanism can spray the flushing liquid from the liquid outlet of the fitting block to the accommodating gap formed by the conical surface of the fitting part and the inner periphery of the mounting seat cavity. Under the action of closing, the accommodating gap overflows into the accommodating groove on the periphery of the fitting part. The overflowing liquid can contact the excitation block at the corresponding position on the front side. The inner conical surface of the excitation block can move upward under the impact of the water liquid to open the overflow liquid gap. The sprayed water liquid can laterally flush the fine mineral particles accumulated on the front side of the excitation block. Through the flushing from the bottom side of the shielding pad and the fitting part, it can be closer to the position where the fine particles accumulate. Cooperating with the vertical water flow of the jig, it can effectively improve the backwashing effect and avoid the interference of the fine particles with the diaphragm main body.

[0026] 3. In the present invention, through the designed flushing guiding mechanism, when the diaphragm body vibrates to stimulate water flow, the guiding pad can be pushed. The bottom inclined surface of the guiding pad drives the moving block to move under the impact of the water flow. The movement of the moving block can squeeze one side of the contraction part. When the contraction part is pressed, the pressure in the inner cavity of the accommodation seat can change. The pressed accommodation cavity can cause the water liquid injected inside to be accelerated and sprayed from the bottom guiding groove to the liquid outlet of the fitting block. The water liquid sprayed from the liquid outlet of the fitting block can be ejected and trigger the excitation block to move upward. The upward moving excitation block can open the flushing gap, enabling water to be added to the bin during the working process. Moreover, the water pressure when the water flow rushes out can prevent large particles from entering the fitting part and the top of the excitation block, improving the gap fitting effect of the diaphragm body. Through the conical fitting of the fitting part, the sliding particles can be guided by the conical surface to roll towards the inner side away from the gap, reducing the residual gap particles of the shielding pad fitting part and improving the durability effect.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0042] Please refer to Figures 1 - 12 , the present invention provides a technical solution: a jig with a flushing mechanism, including a base 1, a hopper 2 is connected to the top of the base 1 through a support pillar 4, the bottom of the hopper 2 is connected with a protective shell 5, and a mounting base 6 is arranged in the inner cavity of the protective shell 5. A diaphragm body 10 is installed in the mounting base 6. A driving part 3 is arranged on the top of the base 1. By driving the diaphragm body 10 by the driving part 3, the sampling medium in the hopper 2 is driven. A shielding mechanism 7 is installed in the inner cavity of the mounting base 6. The gap between the diaphragm body 10 and the mounting base 6 is shielded by the shielding mechanism 7. The shielding mechanism 7 includes a shielding pad 701. A plurality of flushing guiding mechanisms 8 are arranged on the periphery of the shielding pad 701. The flushing liquid is pumped out from the gap between the diaphragm body 10 and the mounting base 6 through the flushing guiding mechanisms 8 for flushing;

[0043] The bottom of the shielding pad 701 is integrally connected with a fitting part 702. The cross-sectional shape of the fitting part 702 is conical, and the conical end of the fitting part 702 is located radially inside the mounting base 6. A accommodating gap is formed between the conical surface of the fitting part 702 and the peripheral side of the inner cavity of the mounting base 6.

[0044] Specifically, through the designed shielding mechanism 7, when ore particles are deposited on the top side of the diaphragm body 10, the shielding pads 701 and the fitting parts 702 located on the peripheral side can fully enclose the device gap between the diaphragm body 10 and the mounting seat 6, which is beneficial to avoiding the wear of the fine particles and the peripheral side of the diaphragm body 10 through the setting of the fitting parts 702. The bottom side of the fitting part 702 can be flushed with liquid through the flushing guiding mechanism 8. Through the flushing liquid, the fine particles can be flushed from the side of the diaphragm body 10 to the axial position. Compared with the diaphragm body 10 placed in the traditional device, it is beneficial to improve the wear-resistant life of the peripheral side of the diaphragm body 10.

[0045] Please refer to Figures 10 - 12 , a plurality of accommodating grooves 703 are formed around the conical part of the shielding pad 701 along the axis. An excitation mechanism 9 is arranged in the accommodating grooves 703. The excitation mechanism 9 includes an excitation block 901, and the excitation block 901 is configured to jump along the axis direction of the shielding pad 701. Through the movement of the jumping excitation block 901, the flushing liquid is ejected from the accommodating gap to flush the gap between the diaphragm body 10 and the mounting seat 6;

[0046] Specifically, through the designed excitation mechanism 9, in order to avoid the accumulation of fine mineral particles when the fitting part 702 of the shielding pad 701 contacts the diaphragm body 10, when the external pumping equipment sends the flushing liquid into the flushing guiding mechanism 8, the flushing mechanism can eject the flushing liquid from the liquid outlet side of the fitting block 807 to the accommodating gap formed by the conical surface of the fitting part 702 and the peripheral side of the inner cavity of the mounting seat 6. Under the action of closing, the accommodating gap overflows into the accommodating grooves 703 on the peripheral side of the fitting part 702. The overflowing liquid can contact the corresponding excitation block 901 at the front side. The inner conical surface of the excitation block 901 can move upward under the impact of the water liquid to open the overflow liquid gap. At this time, the ejected water liquid can laterally flush the fine mineral particles accumulated on the front side of the excitation block 901. Through the flushing from the bottom side of the shielding pad 701 and the fitting part 702, it can be closer to the position where the fine particles accumulate, improve the backwashing effect, and avoid the interference of the fine particles with the diaphragm body 10.

[0047] The cross-sectional shape of the excitation block 901 on the side close to the mounting seat 6 is arc-shaped, and the side surface of the excitation block 901 in contact with the accommodating groove 703 on the inner side has a conical surface. The flushing liquid contacts the conical surface of the excitation block 901 through the flushing guiding mechanism 8 and pushes the excitation block 901 to move upward.

[0048] Furthermore, the arc surface of the excitation block 901 on the side close to the mounting seat 6 can reduce the water body contact resistance when moving upward, improve the processing efficiency, and the inner conical surface of the excitation block 901 can improve the contact effect with the excitation water flow, increase the water flow velocity and the jacking effect through the abutment against the water flow.

[0049] One side of the excitation block 901 is connected to a fixed plate 902. Both sides of the top of the fixed plate 902 are connected to telescopic rods 903. A support plate 905 is connected between the other ends of the two telescopic rods 903. Both sides of the top of the support plate 905 are connected to mounting members 906. The mounting members 906 are connected to one side of the top of the inner cavity of the accommodation groove 703. A spring 904 is sleeved on the outer side wall of the telescopic rod 903. The two ends of the spring 904 are respectively connected to the corresponding positions on one side of the fixed plate 902 and the support plate 905;

[0050] Furthermore, through the designed telescopic rod 903 and spring 904, the telescopic rod 903 has a fixed part and a telescopic part that are coaxially arranged and can slide relative to each other. When the telescopic part expands and contracts, it can press the spring 904. The spring 904 can use its own elastic force to make the excitation block 901 fully contact the bottom diaphragm body 10 at the end of backwashing, which is beneficial to improving the effect of the shielding pad 701 fitting part 702 and the excitation block 901 closing the diaphragm body 10;

[0051] Please refer to Figures 5 - 9 , the flushing guiding mechanism 8 includes an accommodation seat 804. The accommodation seat 804 is connected to one side of the inner cavity of the mounting seat 6. A plurality of liquid inlet holes 805 are opened in the bottom of the accommodation seat 804 along the width direction. A guiding groove 806 is connected to the bottom of the accommodation seat 804. One side of the guiding groove 806 communicates with a fitting block 807. The liquid outlet at the top of the fitting block 807 extends to one side of the shielding pad 701. A liquid injection ring 11 is connected between the tops of a plurality of accommodation seats 804, and the liquid injection ring 11 is connected to an external pumping mechanism through a pipeline;

[0052] The cross-sectional shape of the fitting block 807 is triangular, and the inclined surface at the top of the fitting block 807 extends to the bottom of the shielding pad 701;

[0053] The flushing guiding mechanism 8 further includes a guiding pad 801. One side of the guiding pad 801 is connected to a moving block 802. The moving block 802 is slidably connected to a sliding groove opened on the periphery of the shielding mechanism 7. The other side of the moving block 802 is connected to a contraction part 803. The contraction part 803 is connected to the inner cavity of the accommodation seat 804. The guiding pad 801 is driven by water flow to drive the contraction part 803 to contract, accelerating the flow of the flushing liquid in the inner cavity of the accommodation seat 804;

[0054] The contraction part 803 is a flexible membrane body, and the middle of the flexible membrane body is connected to one side of the moving block 802.

[0055] Specifically: Through the designed flushing guiding mechanism 8, when the diaphragm body 10 vibrates, the flow of the liquid can push the guiding pad 801. The bottom inclined surface of the guiding pad 801 can drive the moving block 802 to move when impacted by the water flow. The movement of the moving block 802 can squeeze one side of the contraction part 803. When the contraction part 803 is pressed, the pressure in the inner cavity of the accommodating seat 804 can change. The pressed accommodating cavity can cause the internally injected liquid to be accelerated and sprayed from the bottom guiding groove 806 to the liquid outlet of the fitting block 807. The liquid sprayed from the liquid outlet of the fitting block 807 can be ejected and trigger the excitation block 901 to move upward. The upward moving excitation block 901 can open the flushing gap, thereby enabling the addition of water to the bin 2 during the working process. And the water pressure when the water flow flushes out can prevent large particles from entering the fitting part 702 and the top of the excitation block 901, improving the gap fitting effect of the diaphragm body 10. Through the tapered fitting of the fitting part 702, the sliding particles can be guided by the conical surface to roll away from the gap towards the inner side, reducing the residual particles in the gap between the shielding pad 701 and the fitting part 702, and improving the durability effect.

[0056] Through the designed contraction part 803, the impact during the movement of the slider can drive the contraction of the flexible membrane body inside the chassis to change the pressure in the liquid cavity of the accommodating seat 804, accelerating the pumping of the flushing liquid;

[0057] Among them, in this embodiment, the added liquid can be other jigging media that can be understood by those skilled in the art;

[0058] Working principle: During use, when an external pumping device sends the flushing liquid into the flushing guiding mechanism 8, the flushing mechanism sprays the flushing liquid from the liquid outlet side of the fitting block 807 into the accommodating gap formed between the tapered surface of the fitting part 702 and the circumferential side of the inner cavity of the mounting seat 6. Under the action of being closed, the accommodating gap overflows into the accommodating groove 703 on the circumferential side of the fitting part 702. The overflowing liquid contacts the excitation block 901 at the corresponding position on the front side. The inner tapered surface of the excitation block 901 moves upward under the impact of the liquid to open the overflow liquid gap. At this time, the sprayed liquid laterally flushes the mineral fine particles accumulated on the front side of the excitation block 901;

[0059] When the diaphragm body 10 vibrates, the flow of water liquid drives the guiding pad 801. The bottom inclined surface of the guiding pad 801 drives the moving block 802 to move under the impact of the water flow. The moving block 802 moves and squeezes the contraction part 803 on one side. When the contraction part 803 is pressed, the internal pressure of the accommodating seat 804 changes. The pressed accommodating cavity causes the water liquid injected inside to be accelerated and sprayed from the bottom guiding groove 806 to the liquid outlet of the fitting block 807. The water liquid sprayed from the liquid outlet of the fitting block 807 sprays out and triggers the excitation block 901 to move upward. The flushing gap is opened by the upward moving excitation block 901. During the working process, when adding water to the bin 2, the water pressure when the water flow rushes out prevents large particles from entering the fitting part 702 and the top of the excitation block 901, improving the gap fitting effect of the diaphragm body 10.
