Description

Technical Field

[0001] The invention relates to a compound purification technology, and in particular to a compound purification device. Background Art

[0002] Lithium is a metallic element with the symbol Li. Its corresponding single substance is a silvery-white soft metal and the metal with the lowest density. It is used in atomic reactors, light alloys and batteries. Lithium and its compounds are not as typical as other alkali metals, because lithium has a large charge density and a stable helium-type double electron layer, which makes it easy for lithium to polarize other molecules or ions, but it itself is not easily polarized, which affects the stability of it and its compounds.

[0003] Purification refers to the separation of impurities in a mixture to improve its purity. It is an important chemical method for purifying lithium ions from their compounds.

[0004] A Chinese invention patent with publication number CN115501830A discloses a lithium compound purification device and method. The nucleic acid throat swab automatic collection device is driven by a push ring, which drives the card block to move through a connecting rod. The first spring is deformed by force to generate elastic force, and the concave block is placed in the concave groove on the surface of the fixed ring. The push ring is loosened, and the first spring releases the elastic force to drive the card block to be inserted into the slot on the surface of the concave block. When the stirring rod rotates, the scraper can be driven to rotate and clean, and the device can be used. By setting a cleaning device, it is convenient to clean the device. The cleaning is carried out. At the same time, when spraying is needed, the water pipe supplies water to the nozzle through the conduit, and the nozzle sprays and washes the scraper. The motor is turned on, and the motor drives the threaded rod to rotate through the belt, and the threaded rod drives the rack to move in the slide rod. The rack cooperates with the gear to drive the nozzle and the drive rod to rotate and adjust, so as to improve the spraying effect. By setting up the spraying device, it is convenient to spray the cleaning part of the equipment, which can effectively reduce the phenomenon that the surface is easily contaminated with cleaning objects during cleaning, reduce the poor subsequent cleaning effect of the equipment, and thus improve the overall usability of the equipment.

[0005] However, in actual application, there are the following problems:

DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Embodiment 1:

[0039] See also Figure 1-Figure 5 , Figure 7-Figure 8 A compound purification device comprises a kettle body 1, a hollow rotating shaft 2 arranged on the inner wall of the kettle body 1 and a plurality of fixed stirring plates 3 arranged outside the hollow rotating shaft 2, a cleaning mechanism 4 is arranged outside the hollow rotating shaft 2, the cleaning mechanism 4 comprises a connecting shell 41 fixedly connected to the outer surface of the hollow rotating shaft 2, a movable stirring plate 42 is slidably connected to the inner wall of the connecting shell 41, a first electric telescopic rod 43 is fixedly connected to the inner wall of the connecting shell 41, a connecting groove 44 is opened on the inner wall of the kettle body 1, a water retaining bar 45 is arranged on the inner wall of the connecting groove 44, a connecting component 46 is arranged between the water retaining bar 45 and the connecting groove 44, and an assembly component 47 is arranged between the movable stirring plate 42 and the water retaining bar 45;

[0040] The water retaining bar 45 includes a scraper head 451 disposed on one side thereof close to the inner wall of the kettle body 1. The water retaining bar 45 is provided with a flat surface portion 452 located on both sides of the scraper head 451 on one side thereof close to the inner wall of the kettle body 1. The scraper head 451 is slidably connected to the inner wall of the connecting groove 44.

[0041] Specifically, the shape and size of the scraper head 451 are compatible with the connection groove 44, so that after the scraper head 451 enters the connection groove 44, it can better fit with the inner wall of the connection groove 44, so that the connection stability between the water retaining strip 45 and the inner wall of the kettle body 1 is better.

[0042] The connecting assembly 46 is used to connect and fix the water retaining strip 45 to the connecting groove 44;

[0043] The assembly component 47 is used to loosen the connection between the water retaining bar 45 and the connecting groove 44 , and to connect and fix the water retaining bar 45 to the movable stirring plate 42 .

[0044] In this embodiment, the telescopic end of the first electric telescopic rod 43 is fixedly connected to the movable stirring plate 42 , and the telescopic end of the first electric telescopic rod 43 can drive the movable stirring plate 42 to slide linearly along the inner wall of the connecting shell 41 .

[0045] In this embodiment, the connecting component 46 includes a guide groove symmetrically opened on the inner wall of the scraper head 451, and the inner side surface of the guide groove is slidably connected with a clamping rod 461, and an extrusion spring 462 is fixedly connected between the clamping rod 461 and the inner wall of the guide groove. Clamping grooves 463 that are compatible with the clamping rod 461 are opened on both sides of the inner wall of the connecting groove 44.

[0046] Specifically, the clamping rod 461 can be inserted into the inside of the clamping slot 463, and the outer surface of the clamping rod 461 after entering the clamping slot 463 fits with the inner wall of the clamping slot 463, so that the connection stability between the water retaining strip 45 and the inner wall of the kettle body 1 is better.

[0047] In this embodiment, the assembly component 47 includes a vertical groove opened inside the movable stirring plate 42, the bottom end of the inner wall of the vertical groove is fixedly connected with a support spring 471, the top of the support spring 471 is fixedly connected with a clamping plate 472, the clamping plate 472 is provided with a guide inclined portion 473 on the side close to the water retaining bar 45, the water retaining bar 45 is provided with a working groove on the side close to the movable stirring plate 42, the inner side surface of the working groove is slidably connected with a closing block 474, a connecting spring 475 is fixedly connected between the closing block 474 and the inner wall of the working groove, the inner side surface of the working groove is provided with a clamping groove 476 matched with the clamping plate 472, and the position, shape and size specifications of the working groove are all matched with the movable stirring plate 42.

[0048] As the clamping plate 472 moves to the position corresponding to the engaging groove 476, the clamping plate 472 is reset in the reverse direction and enters the engaging groove 476 under the action of the rebound force of the support spring 471, so that the movable stirring plate 42 can be stably connected to the water retaining bar 45 under the cooperation of the clamping plate 472 and the engaging groove 476.

[0049] In this embodiment, the inner wall of the scraper head 451 is provided with an installation cavity connected to the guide groove, the inner side surface of the installation cavity is slidably connected with a sliding block 477, and a linkage rod 478 is rotatably connected between the clamping rod 461 and the sliding block 477. A straight groove connecting the installation cavity and the working groove is provided inside the scraper head 451, and a connecting plate 479 is slidably connected to the inner side surface of the straight groove. The connecting plate 479 is slidably connected to the inner side surface of the straight groove, and the connecting plate 479 is fixedly connected to the sliding block 477. The side of the closing block 474 close to the connecting plate 479 is fixedly connected with a top plate 4710, and the position and size specifications of the top plate 4710 are compatible with the connecting plate 479. When the top plate 4710 drives the sliding block 477 to move away from the top plate 4710, the linkage rod 478 drives the clamping rods 461 on both sides to move closer to each other.

[0050] Specifically, under the limiting and guiding action of the straight groove, the connecting plate 479 can only perform a linear motion consistent with its length direction, and under the guiding action of the connecting plate 479, the movement of the sliding block 477 can be restricted and can only move synchronously with the connecting plate 479.

[0051] In this embodiment, an installation groove is opened inside the movable stirring plate 42, and a second electric telescopic rod 4711 is fixedly installed on the inner side of the installation groove. A wire groove is opened between the installation groove and the straight groove, and a traction wire 4712 that runs through the wire groove is fixedly connected between the telescopic end of the second electric telescopic rod 4711 and the bottom of the clamping plate 472.

[0052] Specifically, after the cleaning work is completed, the telescopic end of the second electric telescopic rod 4711 is contracted to pull one end of the traction line 4712, so that the other end of the traction line 4712 pulls the card plate 472, so that the card plate 472 moves into the vertical groove and withdraws from the inside of the card groove 476, thereby ensuring that the movable stirring plate 42 and the water retaining bar 45 share the force, so that the water retaining bar 45 can be reconnected to the inner wall of the kettle body 1.

[0053] When the kettle body 1 needs to be cleaned during use, the position of the movable stirring plate 42 is aligned with the water retaining bar 45, and then the telescopic end of the first electric telescopic rod 43 is extended to drive the movable stirring plate 42 to move close to the water retaining bar 45, and squeeze the closing block 474, so that the closing block 474 moves toward the inside of the working groove, and compresses the connecting spring 475. As the closing block 474 moves toward the inside of the working groove, the movable stirring plate 42 gradually enters the inside of the working groove. At this time, the card plate 472 moves along with the movable stirring plate 42 in the direction of the card groove 476. The guide inclined surface 473 will contact the corners at the notch of the working groove. As the card plate 472 continues to move, the guide inclined surface 473 will contact the corners at the notch of the working groove. There is an extrusion force between the surface 473 and the corners at the notch of the working groove, and under the guiding action of the guiding inclined surface 473, the clamping plate 472 is subjected to a component force in the same direction of the length of the vertical groove, so that the clamping plate 472 moves toward the inside of the vertical groove and compresses the support spring 471. As the clamping plate 472 gradually enters the inside of the vertical groove, the clamping plate 472 can enter the inside of the working groove. When the clamping plate 472 moves to a position corresponding to the clamping groove 476, under the action of the rebound force of the support spring 471, the clamping plate 472 is reset in the reverse direction and enters the inside of the clamping groove 476, so that under the cooperation of the clamping plate 472 and the clamping groove 476, the movable stirring plate 42 can be stably connected to the water retaining bar 45;

[0054] When the closing block 474 moves toward the inside of the working tank, it will drive the top plate 4710 to move. The movement of the top plate 4710 will gradually contact the connecting plate 479, so that the connecting plate 479 can move synchronously with the top plate 4710. The movement of the connecting plate 479 drives the sliding block 477 to move. The movement of the sliding block 477 drives the linkage rod 478 to move. When the linkage rod 478 moves, it can drive the clamping rods 461 on both sides to continue to move synchronously close to each other and gradually withdraw from the clamping groove 463, so that the scraper head 451 can withdraw from the connecting groove 44. At this time, through the contraction of the telescopic end of the first electric telescopic rod 43, the scraper head 451 can be driven to withdraw from the inside of the connecting groove 44 until its end face is flush with the inner wall of the kettle body 1, and then the hollow rotating shaft 2 is rotated to drive the movable stirring plate 42 to rotate, so that the water retaining bar 45 can rotate, so that the scraper head 451 can rotate synchronously to scrape off the residual compounds attached to the inner wall of the kettle body 1.

[0055] Embodiment 2:

[0056] See also Figure 1-Figure 6 , Figure 8 This embodiment provides a technical solution based on the above embodiment: a spray mechanism 5 is arranged inside the water retaining bar 45, and the spray mechanism 5 includes water inlet grooves 51 symmetrically opened on both sides of the water retaining bar 45, and a plurality of spray ports 52 are arranged on the surface of the plane portion 452, and the spray ports 52 are connected to the water inlet groove 51, and a conducting component 53 is arranged between the closing block 474 and the movable stirring plate 42, and the top of the hollow rotating shaft 2 is fixedly connected to an external water pipe 54 through a connector.

[0057] Specifically, the external water pipe 54 is used to communicate with an external water source to supply water for cleaning work;

[0058] Further, the connector here is used to connect the external water pipe 54, the hollow shaft 2 and the driving source for driving the hollow shaft 2, so as to ensure that the external water pipe 54 can supply water normally during the rotation of the hollow shaft 2;

[0059] Furthermore, the external water pipe 54 here can be fixedly connected to one end of the connector, and the hollow shaft 2 can be fixedly connected to the other end of the connector. At this time, the hollow shaft 2 can rotate relative to the external water pipe 54, and the driving source is connected to the hollow shaft 2 through a pulley drive, so that it can meet the needs of work. The above-mentioned connector connection method is a commonly used method and will not be repeated here.

[0060] In this embodiment, the conducting component 53 includes a first circular groove opened inside the movable stirring plate 42, a sealing sleeve 531 is slidably connected to the inner side of the first circular groove, a first spring 532 is fixedly connected between the sealing sleeve 531 and the inner wall of the first circular groove, an end of the sealing sleeve 531 away from the inner wall of the first circular groove extends to the outside of the first circular groove, a conducting tube 533 is fixedly connected to the inner wall of the first circular groove, an end of the conducting tube 533 away from the inner wall of the first circular groove is flush with an end of the sealing sleeve 531 away from the inner wall of the first circular groove, and a conducting tube 533 is fixedly connected to the hollow rotating shaft 2. The outer side surface of the hose 534 and the conducting pipe 533 is equidistantly provided with a plurality of drain outlets 535, the surface of the closing block 474 is provided with a second circular groove 539 corresponding to the position of the first circular groove, the inner side surface of the second circular groove 539 is slidably connected with a closing plate 536, a second spring 537 is fixedly connected between the closing plate 536 and the inner wall of the second circular groove 539, an annular groove 538 is provided on the inner wall of the closing block 474, a plurality of through grooves 5310 are provided between the annular groove 538 and the second circular groove 539, and a connecting pipe 5311 is fixedly connected between the water inlet groove 51 and the annular groove 538.

[0061] In this embodiment, the shape and size specifications of the conducting tube 533 are compatible with the second circular groove 539. The conducting tube 533 can be inserted into the interior of the second circular groove 539. The diameter value of the second circular groove 539 is smaller than the outer ring diameter value of the closed sleeve 531. The conducting tube 533 is slidably connected to the interior of the closed sleeve 531.

[0062] Specifically, in the non-transportation state, the drainage port 535 on the conducting pipe 533 can be sealed by the sealing sleeve 531;

[0063] Furthermore, when the sealing sleeve 531 moves synchronously with the movable stirring plate 42, it will contact the surface of the sealing block 474 and cannot continue to move forward due to the restriction of the surface, so that the conducting tube 533 can slide relative to the sealing sleeve 531 and enter the second circular groove 539.

[0064] In this embodiment, the number, position and size of the through grooves 5310 match those of the drain port 535 , so that the clean water discharged from the conducting pipe 533 can enter the annular groove 538 .

[0065] When the movable stirring plate 42 moves into the working groove, the sealing sleeve 531 moves to contact the surface of the sealing block 474 and cannot continue to move relative to the sealing block 474. Therefore, the continued movement of the movable stirring plate 42 will drive the guide tube 533 to move and slide relative to the sealing sleeve 531, so that the guide tube 533 can squeeze the sealing plate 536 and enter the second circular groove 539. Under the squeezing of the guide tube 533, the sealing plate 536 moves toward the inside of the second circular groove 539 and compresses the second spring 537. After the guide tube 533 enters the second circular groove 539, it is connected to the drain port 535 and the drain port 535. Under the cooperative connection effect of the through groove 5310, it can be connected with the annular groove 538, so that after the water retaining bar 45 is connected and fixed to the movable stirring plate 42, the conducting pipe 533 and the annular groove 538 are also in a stable connection state. After the connection is completed, clean water is supplied through the external water pipe 54, and under the transportation of the conducting pipe 533, the clean water can enter the annular groove 538, and under the transportation of the connecting pipe 5311, the clean water can enter the water inlet groove 51, and finally be sprayed out from the spray port 52. During the operation of the scraper head 451, both sides of the working part of the scraper head 451 are sprayed synchronously, so that the spray cleaning effect can be better.

[0066] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
