[0034] The embodiment of the present invention can realize the above-mentioned arrangement by driving the driving motor to drive the driving shaft to rotate, so that the driving shaft drives the first cam, the second cam and the mixing element to rotate, so that the mixing element mixes and stirs the lithium carbonate mother liquor inside the processing kettle through rotation, and accelerates the cooling of the lithium carbonate mother liquor through stirring. And when the first cam rotates, the first cam will use its own structure to push the transmission wheel back and forth, so that the transmission wheel starts to drive the transmission element to move outward under the influence of the pushing, and the transmission element uses its own inclined surface to push the inclined surface of the force-bearing element during the outward movement, so that the force-bearing element is affected by the pushing of the inclined surface and drives the extrusion element to descend, so that the rotational force of the driving shaft is converted, and the rotational force is indirectly converted into extrusion force, thereby indirectly providing the water-cooling structure with circulating power of the coolant.

[0035] In this embodiment, a mounting shell 40 is provided on the top of the processing kettle 1; slide grooves 41 are arranged in a cross shape on the mounting shell 40; an extrusion member 42 is slidably installed inside the slide groove 41; the extrusion member 42 is located above the circulation bag 12;

[0036] Force bearing members 43 are arranged on the left and right sides of the top of the extrusion member 42 ; the inner side of the force bearing member 43 is an inclined structure; fanning shafts 44 are arranged on the left and right sides of the interior of the processing kettle 1 ; and connecting members 45 are arranged on the fanning shafts 44 .

[0037] A fan plate 46 is installed on the connecting member 45; the fan plate 46 is a rectangular structure; a first connecting wheel 47 is provided on the circumferential outer wall of the fan shaft 44; a guide member 48 is provided at the inner bottom end of the processing kettle 1; the guide member 48 is an L-shaped structure. A force block 49 is slidably installed on the guide member 48; a force wheel 490 is provided at the inner end of the force block 49;

[0039] The outer wall of the force wheel 490 contacts the outer wall of the second cam 491; a driving rack 492 is arranged on the top of the force block 49; baffles 493 are arranged on the front and rear sides of the force block 49; one end of a second return spring 494 is embedded and installed on the outer side of the baffle 493; the other end of the second return spring 494 is embedded and installed on the inner side of the guide member 48; a transmission shaft 5 is arranged on the left and right sides of the bottom end of the processing kettle 1. The transmission shaft 5 is a cylindrical structure; a second connecting wheel 50 is arranged on the transmission shaft 5; a transmission gear 51 is arranged on the circumferential outer wall of the transmission shaft 5; the transmission gear 51 is meshed and connected with the driving rack 492.

[0041] The embodiment of the present invention can realize that when the driving shaft drives the second cam to rotate, the second cam will use its own structure to start to push the force wheel back and forth, so that the force wheel is forced to drive the force block and the driving rack to move outward, so that the driving rack drives the transmission shaft and the second connecting wheel to rotate under the action of meshing with the transmission gear, and the second connecting wheel drives the driven shaft and the fourth connecting wheel to rotate under the action of the chain and the third connecting wheel, and the fourth connecting wheel drives the fan shaft, the connecting piece and the fan plate to rotate under the action of the chain and the first connecting wheel. When the second cam no longer pushes the force wheel, the force block can be restored under the action of the second reset spring, thereby indirectly resetting the fan shaft and the fan plate, and the fanning action of the fan plate is realized reciprocatingly in this way, so that the fan plate cools the lithium carbonate mother liquor by fanning.

[0042] The embodiment of the present invention can cool the lithium carbonate mother liquor in the processing kettle at the same time by providing a water cooling structure and a fan structure, thereby improving the cooling effect of the cooling device on the lithium carbonate mother liquor.

[0043] The embodiment of the present invention combines the rotational motion of the drive shaft, the up and down reciprocating motion of the extrusion piece, and the fanning motion of the fan plate, so that the stirring structure for stirring the lithium carbonate mother liquor in this embodiment is combined with the cooling structure and the stirring structure and the cooling structure share the same driving device, thereby reducing the number of driving devices arranged and reducing the production cost of lithium carbonate preparation.

[0044] The cooling device also includes a transfer mechanism for transferring the processing kettle 1, the transfer mechanism includes a transfer frame 20, a placement cavity 21 is provided on the top of the transfer frame 20, the processing kettle 1 is placed in the placement cavity 21, a fixed seat 22 is fixedly connected to the left side of the transfer frame 20, a moving wheel 23 is provided at the bottom of the fixed seat 22, and a pull rod 24 is provided at the top of the fixed seat 22. The transfer frame 20 includes a connecting seat 200, a cross plate 201, an auxiliary wheel 202 and a support rod 203. The connecting seat 200 is fixedly connected to the cross plate 201, the auxiliary wheel 23 is fixedly installed on the right bottom of the cross plate 201, the support rod 203 is fixedly installed on the top of the cross plate 201, the top of the connecting seat 200 is fixedly connected to the bottom of the placement cavity 21, and an installation groove 204 is opened on the right side of the connecting seat 200.

[0045] The embodiment of the present invention can place the processing kettle in the embodiment into the placement cavity through the above arrangement, and then the transfer mechanism can be moved by the moving wheels to drive the processing kettle to be transferred. At the same time, the support rod of the embodiment is used to support the placement cavity.

A handle 370 is provided on the top of the traction rod 37. The handle 370 is rotatably mounted on the rotating rod 33.

[0047] The above arrangement enables the embodiment of the present invention to achieve that when the handle drives the traction rod to move upward, the traction rod drives the plug-in block to move upward and compresses the spring, so that the plug-in block is no longer engaged with the tooth groove. When the moving wheel needs to be clamped and positioned, the clamping plate is driven to move toward one side of the moving wheel by rotating the rotating rod, so that the clamping plate clamps the outer wall of the moving wheel to prevent the moving wheel from moving accidentally. Then the handle is released and the plug-in block is driven to move downward under the elastic force of the spring, so that the bottom of the plug-in block is engaged with the tooth groove, thereby positioning the position of the rotating rod to prevent the clamping plate from loosening when the moving wheel is clamped.
