Description

Technical Field

[0001] The present invention relates to the technical field of ore dressing equipment, and particularly to a sawtooth wave jig for ore dressing. Background Art

[0002] Ore dressing refers to the process of separating useful minerals from ores and removing waste minerals. A sawtooth wave jig is a device for gravity ore dressing, mainly used for the separation and enrichment of minerals. It adopts the jigging principle and combines the jigging action of a sawtooth waveform, which can efficiently separate heavy minerals and light minerals in minerals. When using a sawtooth wave jig for gravity separation of minerals, a cam mechanism is used for transmission, and the generated sawtooth waveform pulsation curve makes the upward flow of the jig even and the downward flow rapid, so that mineral particles are stratified according to density differences in the water flow. Heavy mineral particles will settle at the bottom of the trough, while light mineral particles will float or be carried away with the water flow, effectively improving the recovery rate of fine-grained minerals and having a good ore dressing effect on fine-grained materials.

[0003] However, the existing sawtooth wave jigs have the following deficiencies: 1) In the prior art, during the working process of the diaphragm of a sawtooth wave jig, it needs to withstand repeated stretching and compression. Long-term vibration and mechanical pressure will cause wear, aging or tearing of the diaphragm. In order to increase the service life of the diaphragm, lubricating oil needs to be manually and evenly coated on the contact surface between the diaphragm and the connecting hopper, and the operation needs to be stopped, which increases the use cost of the jig. 2) When the diaphragm is damaged and needs to be replaced, the equipment needs to be stopped, and then the fixing ring on the diaphragm needs to be removed with tools. The operation is cumbersome and the replacement of the diaphragm cannot be quickly completed, which increases the maintenance cost of the jig. 3) In the prior art, ore materials are directly poured into the ore dressing tank, and there is a certain drop during the process of pouring the ore materials into the ore dressing tank, which causes the ore materials to impact the screen plate. Over time, it is easy to damage the screen plate and reduce the service life of the screen plate.

[0004] Therefore, we propose a sawtooth wave jig for ore dressing to solve the problems mentioned above. Summary of the Invention

[0005] The object of the present invention is to provide a sawtooth wave jig for ore dressing, which can add lubricating oil to the diaphragm more quickly while realizing non-stop operation. First, the knob drives the threaded rod to move, and then the threaded rod drives the fixed frame to move in the moving groove, and the telescopic rod limits the moving path of the fixed frame. Then, the fixed frame drives the baffle to move, so that the baffle moves into the storage groove from the annular drain port. Then, the lubricating oil will fall on the surface of the connecting hopper from the annular drain port, and a part of the lubricating oil flows into the groove through the drainage groove. Since the operation is not stopped, the movement of the diaphragm and the convex block will evenly coat the lubricating oil on the surfaces of the connecting hopper and the groove, and the movement path of the diaphragm is limited by the groove and the convex block, improving the stability of the diaphragm movement. After the lubricating oil is added to a certain extent, the knob can be used to drive the threaded rod to move, and then the threaded rod drives the fixed frame and the baffle to move back to their original positions, and the sealing strip can increase the sealing performance at the fixed frame and the baffle, reducing the use cost of the jig to solve the problems raised in the above background technology.

The liquid storage box 201 is fixedly installed on the outer surface of the connecting hopper 104. Storage grooves 202 are opened on both sides of the outer surface of the liquid storage box 201. A baffle 203 is slidably connected to the inside of the storage groove 202. A fixing frame 204 is fixedly installed on the outer surface of the baffle 203. A threaded rod 205 is fixedly installed on one side of the outer surface of the fixing frame 204. A knob 206 is fixedly installed at one end of the outer surface of the threaded rod 205.

The convex block 211 is fixedly installed inside the diaphragm 105. A drainage groove is opened at one end inside the groove 210.

[0023] The effect achieved by the entire Embodiment 1 is as follows: While achieving non-stop operation, lubricating oil can be added to the diaphragm 105 more quickly. First, the knob 206 drives the threaded rod 205 to move. Subsequently, the threaded rod 205 drives the fixed frame 204 to move in the moving groove, and the telescopic rod 208 limits the moving path of the fixed frame 204. Then, the fixed frame 204 drives the baffle 203 to move, causing the baffle 203 to move into the storage groove 202 from the annular drainage port. Then, the lubricating oil will fall onto the surface of the connecting hopper 104 from the annular drainage port, and a part of the lubricating oil flows into the groove 210 through the drainage groove. Due to the non-stop operation, the movement of the diaphragm 105 and the convex block 211 evenly coats the lubricating oil on the surfaces of the connecting hopper 104 and the groove 210, and the movement path of the diaphragm 105 is limited by the groove 210 and the cam, improving the stability of the movement of the diaphragm 105. After the lubricating oil is added to a certain extent, the knob 206 can be used to drive the threaded rod 205 to move. Subsequently, the threaded rod 205 drives the fixed frame 204 and the baffle 203 to move back to their original positions, and the sealing strip 209 can increase the sealing performance at the fixed frame 204 and the baffle 203, reducing the use cost of the jig.

[0024] Embodiment 2, according to Figure 3 、 Figure 5 and Figure 6 As shown, the replacement mechanism 3 includes a base 301, the base 301 is fixedly installed at the bottom end of the diaphragm 105, both sides of the bottom end of the base 301 are fixedly installed with insertion plates 302, the top end of the conical hopper 106 is provided with a slot 303, the insertion plates 302 are slidably connected to the inner side of the slot 303, and both sides of the outer surface of the insertion plates 302 and the inner side of the conical hopper 106 are provided with card slots, the inner side of the card slots is slidably connected with a limiting block 304, one end of the outer surface of the limiting block 304 is fixedly installed with a first return spring 305 and a pull rod 306, one end of the outer surface of the first return spring 305 is fixedly installed inside the card slot, one end of the outer surface of the pull rod 306 is fixedly installed with a limiting rod 307, and the pull rod 306 is slidably connected to the inner side of the conical hopper 106, and the limiting rod 307 is slidably connected to the inner side of the insertion plate 302.

[0025] The effect achieved by the entire Embodiment 2 is as follows: The rapid replacement of the diaphragm 105 is realized. First, the diaphragm 105 is knocked off the connecting hopper 104, and then the pull rod 306 is pulled, so that the pull rod 306 drives the limiting rod 307 and the limiting block 304 away from the insertion plate 302, and the moving path of the limiting block 304 can be limited by the limiting rod 307. Then, the base 301 and the diaphragm 105 can be removed for replacement. Subsequently, the pull rod 306 is pulled, so that the pull rod 306 drives the first return spring 305 to be compressed. Then, the insertion plate 302 on the base 301 is aligned with the slot 303 and inserted, and the pull rod 306 is released. Then, the reset of the first return spring 305 drives the limiting block 304 and the limiting rod 307 to insert into the insertion plate 302, thereby completing the limitation of the base 301, and reducing the maintenance cost of the jig.

[0026] Embodiment 3, according to Figure 3 、 Figures 7-9 As shown in, the guiding mechanism 4 includes a guiding plate 401. The guiding plate 401 is fixedly installed at the bottom end of the feeding hopper 103, and a movable plate 402 is slidably connected to the inner side of the guiding plate 401. A slider 404 is fixedly installed on the outer surface of the movable plate 402, and the bottom end of the movable plate 402 is in contact with the sieve plate 102. A chute 403 is formed on the outer surface of the guiding plate 401, and the slider 404 is slidably connected to the inner side of the chute 403. A plurality of groups of second return springs 405 are fixedly installed at the top end and the bottom end of the guiding plate 401 and the movable plate 402, and a telescopic plate 406 is fixedly installed at the top end of the movable plate 402. The top end of the telescopic plate 406 is fixedly installed at the bottom end of the guiding plate 401.

[0027] The effect achieved by the entire Embodiment 3 is as follows: While guiding the ore to be input, the ore accumulated on the movable plate 402 can be washed down more quickly. First, the ore will fall on the sieve plate 102 after passing through the arc-shaped moving path composed of the guiding plate 401 and the movable plate 402, preventing the ore from directly falling and damaging the sieve plate 102. Then, the fluctuation of the water flow will drive the movable plate 402 to reciprocate inside the guiding plate 401, and the moving path of the movable plate 402 is limited by the chute 403 and the slider 404. Then, the movable plate 402 drives the second return spring 405 and the telescopic plate 406 to move. The telescopic plate 406 is located at the connection between the movable plate 402 and the guiding plate 401, which can prevent the ore from splashing into the inside of the guiding plate 401 and affecting the normal movement of the movable plate 402. Then, through the reciprocating movement of the movable plate 402 in cooperation with the fluctuation of the water flow, the ore accumulated on the movable plate 402 can be washed down on the sieve plate 102 more quickly, improving the separation efficiency of the jig.

[0028] The working principle of the whole device is as follows: During the use of the jig, water is first added into the beneficiation tank 101 through the communication port on the connecting hopper 104, so that the water passes through the sieve holes on the sieve plate 102 to form a water flow in the beneficiation tank 101. Then, the motor 108 drives the cam in the cam drive box 109 to move up and down, causing the cam to drive the conical hopper 106 to move up and down. Subsequently, the conical hopper 106 drives the diaphragm 105 to move up and down on the surface of the connecting hopper 104, and the reciprocating compression and expansion of the diaphragm 105 generate a sawtooth-shaped jigging force, making the water flow in the beneficiation tank 101 rise evenly and fall rapidly. During the movement of the diaphragm 105, the shock-absorbing spring 112 can buffer the movement of the conical hopper 106 and the support plate 110, and the groove 210 and the convex block 211 limit the movement path of the diaphragm 105, improving the stability of the movement of the diaphragm 105. Subsequently, the ore is fed from the feed hopper 103. The ore will pass through the arc-shaped movement path composed of the guide plate 401 and the movable plate 402 and then fall on the sieve plate 102 to prevent the ore from directly falling and damaging the sieve plate 102. Then, the ore will be stratified according to the density difference in the water flow and discharged from the discharge pipes on the conical hopper 106 and the beneficiation tank 101 respectively. During the feeding process of the ore, the fluctuation of the water flow will drive the movable plate 402 to reciprocate inside the guide plate 401, and the chute 403 and the slider 404 limit the movement path of the movable plate 402. Then, the movable plate 402 drives the second return spring 405 and the telescopic plate 406 to move. The telescopic plate 406 is located at the connection between the movable plate 402 and the guide plate 401, which can prevent the ore from splashing into the inside of the guide plate 401 and thus affecting the normal movement of the movable plate 402. Then, through the reciprocating movement of the movable plate 402 in cooperation with the fluctuation of the water flow, the ore accumulated on the movable plate 402 can be washed onto the sieve plate 102 more quickly, improving the sorting efficiency of the jig. When it is necessary to coat lubricating oil on the connection between the diaphragm 105 and the connecting hopper 104, the knob 206 can be rotated to drive the threaded rod 205 to move. Subsequently, the threaded rod 205 drives the fixing frame 204 to move in the moving groove, and the telescopic rod 208 limits the movement path of the fixing frame 204. Then, the fixing frame 204 drives the baffle 203 to move, so that the baffle 203 moves into the storage groove 202 from the annular drain port. Then, the lubricating oil will fall on the surface of the connecting hopper 104 from the annular drain port, and a part of the lubricating oil will flow into the groove 210 through the drainage groove. Since the operation is not stopped, the movement of the diaphragm 105 and the convex block 211 will evenly coat the lubricating oil on the surfaces of the connecting hopper 104 and the groove 210. After the lubricating oil is added to a certain extent, the knob 206 can be rotated to drive the threaded rod 205 to move. Subsequently, the threaded rod 205 drives the fixing frame 204 and the baffle 203 to move back to their original positions, and the sealing strip 209 can increase the sealing performance at the fixing frame 204 and the baffle 203.While the operation is in progress without shutting down the machine, the work of adding lubricating oil to the diaphragm 105 can be completed more quickly, reducing the usage cost of the jigger. When the diaphragm 105 needs to be replaced, first knock the diaphragm 105 off the connecting hopper 104, and then pull the pull rod 306, so that the pull rod 306 drives the limiting rod 307 and the limiting block 304 away from the plug board 302, and the movement path of the limiting block 304 can be limited by the limiting rod 307. Then the base 301 and the diaphragm 105 can be removed for replacement. Subsequently, pull the pull rod 306, so that the pull rod 306 drives the first return spring 305 to be compressed. Then insert the plug board 302 on the base 301 into the slot 303, and release the pull rod 306. Then, driven by the return of the first return spring 305, the limiting block 304 and the limiting rod 307 are inserted into the plug board 302, thus completing the limitation of the base 301, providing convenience for the quick replacement of the diaphragm 105 and reducing the maintenance cost of the jigger.
