Description

Technical Field

[0001] The invention relates to the technical field of rare earth extraction, in particular to a rare earth liquid metering and conveying device for a rare earth extraction tank. Background Art

[0002] Rare earth oxides refer to oxides of 15 lanthanide elements with atomic numbers 57 to 71 in the periodic table, as well as oxides of 17 elements such as scandium (Sc) and yttrium (Y) that have similar chemical properties to lanthanide elements. Rare earth elements have been widely used in the fields of petroleum, chemical industry, metallurgy, textile, ceramics, glass, permanent magnet materials, etc.

[0003] In a rare earth liquid metering and conveying device in a rare earth extraction tank disclosed by authorization announcement number CN207376106U, the device includes an extraction tank body, an observation port is provided on the inner wall of the extraction tank body, a metering box is fixedly connected to the inner wall of the extraction tank body, a placement groove is provided on the outer surface of the metering box, an observation window is fixedly connected to the inner wall of the placement groove, a scale is fixedly connected to the front of the observation window, an exhaust pipe is provided on the outside of the metering box, the exhaust pipe is connected to the metering box, and a connecting pipe is provided on the outside of the metering box. The rare earth liquid metering and conveying device in the rare earth extraction tank can convey the rare earth liquid in the metering box through the output pipe by driving the piston up and down by a motor, which effectively reduces the layout of the pipeline. Compared with the electromagnetic pump, this solution conveying device is more stable, efficient and cheaper. The above-mentioned device directly extracts and conveys the liquid through the movement of the piston, and cannot achieve absolute sealing. The piston needs to move when in use, and the movement of the piston will affect the sealing of the piston. Therefore, the liquid may leak through the piston. When conveying rare earth liquid, a metering pump is generally used for conveying. When using the metering pump, as long as the elastic membrane is not damaged, the liquid will not leak. However, no matter whether the above-mentioned direct piston conveying or metering pump conveying is used for conveying, during conveying, the piston first sucks the liquid and then presses the liquid out for one reciprocating movement. In this way, the piston can only complete one liquid conveying for one reciprocating movement, which is not only inefficient, but also not stable enough for such conveying.

[0004] To this end, we propose a rare earth liquid metering and conveying device for a rare earth extraction tank to solve the above problems. Summary of the invention

In this way, the position of the vertical rod 29 is adjusted to change the length of the vertical rod 29 driving the strip sleeve 15 to make a reciprocating movement, and the length of the strip sleeve 15 to make a reciprocating movement can be changed. The length of the strip sleeve 15 to drive the connecting rod 16, the slide rod 11 and the piston 10 to reciprocate can be changed. By adjusting the length of the reciprocating movement of the piston 10, the amount of liquid pressed out during one reciprocating movement of the piston 10 can be adjusted, thereby changing the speed of the device when conveying liquid.

[0037] Furthermore, a support plate 43 is fixedly sleeved on the outer wall of the end cover 6, and the bottom of the support plate 43 is fixedly connected to the bottom plate 2; by providing the support plate 43, the end cover 6 can be supported.

[0038] In the present invention, when it is necessary to extract the liquid in the extraction tank body 1, the motor 21 can be started, so that the motor 21 drives the second gear 20 to rotate, the rotating second gear 20 drives the first gear 19 to rotate, the rotating first gear 19 drives the support tube 18 to rotate, the rotating support tube 18 drives the housing 22 to rotate, and the rotating housing 22 can drive the slider 24, the vertical rod 29 and the sleeve cap 42 to rotate, so that the sleeve cap 42 drives the strip sleeve 15 and the connecting rod 16 to reciprocate, and the reciprocating connecting rod 16 drives the two slide bars 11 to reciprocate. When the left slide bar 11 moves to the right, the moving slide bar 11 drives the piston 10 connected thereto to move right, so that the piston 10 presses the medium in the cavity 8 into the cavity 4, and the medium entering the cavity 4 presses the elastic membrane 5, so that the elastic membrane 5 is deformed, and the deformed elastic membrane 5 presses the medium in the cavity 4 out through the upper one-way valve 14 to complete the delivery of the liquid.

[0039] When the left slide bar 11 moves to the right, the right slide bar 11 moves to the right at the same time, and the moving slide bar 11 drives the piston 10 connected thereto to move to the right, and the moving piston 10 extracts the medium in the cavity 4, so that negative pressure is generated on one side of the cavity 4, and the cavity 4 with negative pressure drives the elastic membrane 5 to deform. At this time, the cavity 4 extracts the liquid in the extraction tank body 1 through the one-way valve 14 and the three-way pipe 13 under the connecting shell 3, so that when the right slide bar 11 moves to the left, the liquid is pressed out. In this way, two cavities 4 are set up, and when one cavity 4 and the elastic membrane 5 are absorbing liquid, the other cavity 4 and the elastic membrane 5 therein are discharging liquid, and there will be no pause, which not only improves the stability of liquid transportation, but also improves the efficiency of liquid transportation;

[0040] When adjusting the speed of liquid feeding, the toggle ring 37 can be rotated so that the toggle ring 37 drives the rotating rod 36 to rotate, the rotating rotating rod 36 drives the worm 35 to rotate, the rotating worm 35 drives the worm wheel 33 to rotate, the rotating worm wheel 33 drives the shaft 31 and the second wire drum 32 to rotate, the rotating second wire drum 32 winds and pulls the second pull rope 34, so that the second pull rope 34 pulls the adapter block 28, so that the adapter block 28 moves, the moving adapter block 28 pulls the first pull rope 27, so that the first pull rope 27 drives the first wire drum 26 to rotate, and the rotating first wire drum 26 drives the first threaded rod 2 5 is rotated, the rotating first threaded rod 25 drives the slider 24 to move, and the moving slider 24 drives the vertical rod 29 and the sleeve cap 42 to move. In this way, the positions of the vertical rod 29 and the sleeve cap 42 are adjusted to change the length of the vertical rod 29 and the sleeve cap 42 driving the strip sleeve 15 to make a reciprocating movement. Changing the length of the reciprocating movement of the strip sleeve 15 can change the length of the reciprocating movement of the connecting rod 16, the slide rod 11 and the piston 10 driven by the strip sleeve 15. By adjusting the reciprocating length of the piston 10, the amount of liquid pressed out during one reciprocating movement of the piston 10 can be adjusted, thereby changing the speed of the device when conveying liquid;

[0041] When the positions of the vertical rod 29 and the cap 42 are adjusted in reverse, the toggle ring 37 is reversed. After the toggle ring 37 is reversed, the mainspring 41 drives the first threaded rod 25 to reverse, and the reversed first threaded rod 25 drives the vertical rod 29 and the cap 42 to move in the opposite direction.

[0042] When the first threaded rod 25 rotates and drives the slider 24 and the vertical rod 29 to move, the second threaded rod 38 rotates accordingly. The rotating second threaded rod 38 can drive the counterweight 39 to move. The moving counterweight 39 balances the weight offset generated when the slider 24 and the vertical rod 29 move, so as to ensure the weight balance of the housing 22 and the stability of the housing 22 when it rotates.

[0043] And because the first pull rope 27 and the second pull rope 34 are connected by the adapter block 28, when the first pull rope 27 rotates, the rotating first pull rope 27 will not drive the second pull rope 34. In this way, when the device is running, the first pull rope 27 can also be pulled by the shaft rod 31 and the second pull rope 34 for adjustment, thereby facilitating the adjustment of the speed of conveying the liquid.
