Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lithium carbonate purification, in particular to an anti-clogging pipeline system. Background Art
[0002] The continuous carbonization and pyrolysis process commonly used in the purification of industrial-grade lithium carbonate requires a thickener device that requires precise control of material flow and valve opening. If the flow rate is too large, it may cause overflow due to the inability of the thickener to keep up with the separation and sedimentation speed. Because all devices and pipelines are covered with thermal insulation materials, the overflowing lithium bicarbonate solution may not be completely decomposed and may continue to pyrolyze in the pipeline from the thickener to the precision filter, and may even pyrolyze in the precision filter. The pyrolysis of lithium bicarbonate solution will produce lithium carbonate solids. The lithium carbonate pyrolyzed in the pipeline can cause blockage of the pipeline and precision filter.
[0003] It is necessary to backwash or disassemble the pipes and precision filters to remove the blockage, which is time-consuming and labor-intensive, and affects the continuity of the industrial-grade lithium carbonate purification process. The existing technology also has a method of ensuring continuous production by connecting spare precision filters in parallel, but the precision filters are expensive, which greatly increases the production cost. Utility Model Content
[0004] In order to solve the technical problems existing in the background technology, the utility model proposes an anti-clogging pipeline system.
[0005] The anti-clogging piping system includes a first pipe body for connecting a thickener and a precision filter to transfer lithium carbonate solution and lithium bicarbonate solution overflowing from the thickener to the precision filter. The system also includes: a second pipe body, a container, and a pump. The second pipe body is connected to the first pipe body through a feed port provided on the side wall of the first pipe body, and the first and second pipe bodies are sealed. The second pipe body is connected to the container through the pump so that the pump injects the medium in the container into the first pipe body through the second pipe body to prevent lithium bicarbonate from being pyrolyzed into lithium carbonate and then precipitated in the first pipe body.
[0006] Furthermore, the medium is specifically carbon dioxide.
[0007] Furthermore, the medium is specifically pure water.
[0008] Furthermore, the medium is specifically a carbonic acid solution.
[0009] Furthermore, the anti-clogging piping system also includes a temperature regulating device, which is assembled in the container to reduce the temperature of the carbonated solution in the container to be lower than the temperature of the solution in the first pipe body.
[0010] Furthermore, a heat-insulating layer is provided on the second tube body so that the temperature of the carbonated solution in the container, which is lower than the temperature of the solution in the first tube body, is always lower than the temperature of the solution in the first tube body before being injected into the first tube body.
[0011] Furthermore, the anti-clogging pipeline system includes multiple second tubes, multiple pumps, and containers. Feed ports are opened on the side walls of the front section, middle section, and end section of the first tube. The multiple second tubes are connected to the first tube body through the multiple feed ports one by one. The multiple second tubes are sealed with the first tube body. The multiple second tubes are connected to the containers one by one through multiple pumps so that the pumps inject the medium in the container into the first tube body through the multiple second tubes.
[0012] Furthermore, the second tube body includes multiple branch tubes and a main tube. The multiple branch tubes are connected to the first tube body one by one through multiple feed ports located on the side walls of the front section, middle section, and end section of the first tube body, respectively. The other ends of the multiple branch tubes are connected to one end of the main tube, and the other end of the main tube is connected to the container through a pump, so that the pump injects the medium in the container into various places in the first tube body through the multiple feed ports.
[0013] The beneficial effects of the utility model are:
[0014] By adding low-cost equipment to the first tube, a second tube can be introduced into the first tube to prevent the lithium bicarbonate solution from thermally decomposing into lithium carbonate solids, effectively avoiding the risk of pipeline and precision filter clogging and ensuring the normal and continuous progress of the industrial-grade lithium carbonate purification process.
[0015] Providing a temperature regulating device in the container and providing a heat-insulating layer on the second tube body can reduce the temperature of the lithium bicarbonate solution in the first tube body, further preventing the lithium bicarbonate solution from thermally decomposing into lithium carbonate solid. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 This is a schematic diagram of the anti-clogging piping system according to the first embodiment of the present invention.
[0017] Figure 2 This is a schematic diagram of an anti-clogging piping system according to the second embodiment of the present invention. DETAILED DESCRIPTION
[0018] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.
[0019] like Figure 1 、 Figure 2As shown, the anti-clogging piping system includes a first tube body 1 for connecting a thickener and a precision filter, and is characterized in that it also includes: a second tube body 2, a container 3, and a pump 4. The second tube body 2 is connected to the first tube body 1 through a feed port opened on the side wall of the first tube body 1, and the first tube body 1 and the second tube body 2 are sealed. The second tube body 2 is connected to the container 3 through the pump 4 so that the pump 4 injects the medium in the container 3 into the first tube body 1 through the second tube body 2 to prevent lithium bicarbonate from being pyrolyzed into lithium carbonate in the first tube body 1 and then precipitated.
[0020] The medium is introduced into the first tube body 1 through the second tube body 2, which prevents the high-temperature lithium bicarbonate overflowing into the first tube body from being thermally decomposed into solid lithium carbonate, thereby avoiding the problem of clogging of the pipeline and the subsequent precision filter, and ensuring the normal and continuous operation of the industrial-grade lithium carbonate purification process.
[0021] The invention is characterized in that the medium is specifically carbon dioxide, which can effectively interfere with the pyrolysis of carbonic acid to form lithium carbonate solid.
[0022] The invention is characterized in that the medium is pure water, which can also interfere with the pyrolysis of carbonic acid to form lithium carbonate solid.
[0023] According to the anti-clogging pipeline system, the medium is specifically a carbonic acid solution, which can make carbon dioxide and lithium bicarbonate solution contact more effectively, thereby more effectively preventing the lithium bicarbonate solution from thermally decomposing into lithium carbonate solids.
[0024] The device further includes a temperature regulating device 5, which is mounted in the container 3 and is used to lower the temperature of the carbonic acid solution in the container 3 to a temperature lower than that of the solution in the first tube 1. The pyrolysis of lithium bicarbonate solution to produce lithium carbonate requires heat, and the introduction of a carbonic acid solution having a lower temperature than that of the lithium bicarbonate solution in the first tube 1 into the first tube 1 cools the lithium bicarbonate solution, further hindering the occurrence of the pyrolysis reaction.
[0025] The second tube body 2 is provided with a heat-insulating layer 6 so that the temperature of the carbonated solution in the container 3 , which is lower than the temperature of the solution in the first tube body 1 , is always lower than the temperature of the solution in the first tube body 1 before being injected into the first tube body 1 .
[0026] The provision of the heat-insulating layer 6 improves the cooling effect of the carbonic acid solution on the lithium bicarbonate solution in the first tube 1 , and more effectively hinders the occurrence of the pyrolysis reaction.
[0027] Example 1
[0028] like Figure 1As shown, the anti-clogging piping system includes multiple second tubes 2, multiple pumps 4, and containers 3. Feed ports are opened on the side walls of the front section, middle section, and end section of the first tube 1. Multiple second tubes 2 are connected to the first tube 1 through the multiple feed ports in a one-to-one correspondence. Multiple second tubes 2 are sealed with the first tube 1. Multiple second tubes 2 are connected to the container 3 in a one-to-one correspondence through multiple pumps 4 so that the pumps 4 inject the medium in the container 3 into the first tube 1 through the multiple second tubes 2. This arrangement ensures that the medium that prevents the lithium bicarbonate solution from pyrolyzing to produce solid lithium carbonate can be introduced into various places in the first tube 1, and more efficiently and reliably avoids the occurrence of blockage of the first tube 1 and the precision filter.
[0029] Example 2
[0030] Second tube body 2 includes multiple branch pipes and a main pipe. The multiple branch pipes connect to first tube body 1 through multiple feed ports located on the sidewalls of the front, middle, and rear sections of first tube body 1. The other ends of the multiple branch pipes are connected to one end of the main pipe. The other end of the main pipe is connected to container 3 via pump 4, so that pump 4 injects the medium in container 3 into various locations within first tube body 1 through the multiple feed ports. This arrangement saves pump usage and makes the anti-clogging piping system more compact.
[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
