DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] like Figure 1-6 As shown, an embodiment of the present invention discloses a lithium carbonate washing and filtering device, including a filter box 1, a feed port is arranged at the upper end of the filter box 1, a spray infusion pipe 16 connected to the liquid inlet is arranged at the top of the filter box 1, and a plurality of spray heads 17 are installed on the spray infusion pipe 16.

[0038] An annular mounting groove 10 is provided on the inner wall of the filter box 1, and a plurality of electromagnets 11 are embedded on the side walls of the mounting groove 10. An inner cavity 12 with openings at both ends and a cylindrical structure is sealed and embedded in the mounting groove 10. The inner wall of the inner cavity 12 is flush with the inner wall of the filter box 1, and an annular closed cavity is formed between the two. A pressure regulating pipe 14 is provided on one side of the filter box 1, one end of the pressure regulating pipe 14 is connected to the air pressure regulating mechanism, and the other end is branched into a plurality of output ends extending into the mounting groove 10, and the output ends of the pressure regulating pipe 14 are distributed at the upper and lower ends of each electromagnet 11. The inner cavity 12 includes a plurality of fixed heat-conducting rings 120 and a plurality of elastic rings 121 connected alternately in layers. The fixed heat-conducting rings 120 are fixedly mounted on the filter housing 1 through connectors 122. A plurality of heat-conducting pipes 123 are arranged around and in close contact with the outer wall of the fixed heat-conducting ring 120. A plurality of electric heating iron sheets 124 are embedded in the elastic ring 121 in a circular array. The positions of the plurality of electric heating iron sheets 124 correspond to the positions of the plurality of electromagnets 11 one by one. A heat dissipation fin 125 is arranged on one side of the electric heating iron sheet 124 facing the axis of the elastic ring 121.

[0039] In order to speed up the heat transfer of the electric heating iron sheet 124, the embodiment of the present invention is provided with heat dissipation fins 125 on the electric heating iron sheet 124. The heat dissipation fins 125 are generally metal sheets, which are easily corroded and damaged in a humid environment and in long-term contact with chemical reagents. However, if the electric heating iron sheet 124 is not provided with heat dissipation fins 125, its heat transfer efficiency will be greatly reduced. In the lithium carbonate preparation process, filtering and washing will create a humid environment with a high concentration of chemical reagents. Therefore, in these two processes, the inner cavity 12 can be set as follows: Figure 4 The state shown is specifically that the electromagnet 11 is powered on, at which time the electromagnet 11 firmly absorbs the electric heating iron sheet 124, and then the air pressure regulating mechanism connected to the pressure regulating tube 14 is started to pressurize the inside of the installation groove 10. At this time, all output ends of the pressure regulating tube 14 are simultaneously inflated into the installation groove 10, so that the elastic rings 121 located at the upper and lower ends of the electric heating iron sheet 124 swell in a direction close to each other until they fit each other. At this time, the elastic ring 121 completely wraps the side of the electric heating iron sheet 124 provided with the heat dissipation fin 125, thereby isolating the heat dissipation fin 125 from the space in the filter box 1, thereby achieving heat dissipation of the heat dissipation fin 125. The protection of 25 can protect the heat dissipation fins 125 from moisture and corrosion, and can keep the heat dissipation fins 125 dry to avoid additional heat loss; in the drying process, the humidity in the filter box 1 and the concentration of the chemical reagent are greatly reduced. At this time, in order to allow the electric heating iron sheet 124 to conduct heat to the material more directly, the electric heating iron sheet 124 can be directly exposed to the space in the filter box 1. Specifically, the electromagnet 11 is powered off. At this time, the electromagnet 11 no longer adsorbs the electric heating iron sheet 124, so that at this time, under the elastic recovery of the elastic ring 121, the electric heating iron sheet 124 is quickly reset and restored to the state as shown in the figure. Figure 3In the state shown, the heat dissipation fins 125 are directly exposed to the internal space of the filter box body 1, thereby realizing efficient heat conduction to the material; the air flow activity in the filter box body 1 can be intensified by controlling the repeated expansion or contraction of the elastic ring 121, especially in the drying stage, which can accelerate the discharge of moisture, thereby accelerating the drying speed, and controlling the repeated expansion or contraction of the elastic ring 121 can shake off the material adhered to the inner cavity 12.

[0040] In this embodiment, the elastic ring 121 is in a corrugated shape.

[0041] The embodiment of the present invention can achieve a longer stretching length of the elastic ring of this structure through the above arrangement, thereby reducing the requirements on the material of the elastic ring.

[0043] The embodiment of the present invention can be realized through the above-mentioned setting that when it is necessary to filter the lithium carbonate material, the lithium carbonate material can be put into the interior of the filter box 1 from the feed port of the filter box 1, and the lithium carbonate material can be filtered through the filter mesh shell 3 inside the filter box 1. At the same time, the impurities adhering to the top of the filter mesh shell 3 are cleaned by the pneumatic cleaning mechanism, and the impurities cleaned from the surface of the filter mesh shell 3 are sent to the inside of the collection box 2 through the discharge mechanism 4, and discharged into the inside of the discharge pipe 15, and the impurities are discharged from the inside of the filter box 1 through the discharge pipe 15. That is, the embodiment of the present invention can automatically discharge the impurities accumulated on the surface of the filter mesh shell 3 to the outside through the mutual cooperation of the pneumatic cleaning mechanism and the discharge mechanism, so as to avoid the accumulation of impurities on the surface of the filter mesh shell 3 to affect the filtering effect of the filter net.

The driving device can be a motor or other driving devices. When the stirring shaft 13 rotates, it drives the second synchronous wheel 52 to rotate, thereby driving the synchronous belt 53 to drive the first rotating rod 50 to rotate through the first synchronous wheel 51. The rotation of the first rotating rod 50 drives the first spur gear 54 to rotate, thereby driving the spur gear ring 56 to drive the rotating shell 55 to rotate.

[0047] The embodiment of the present invention can realize that the first arc scraper 30 is driven to rotate by the rotating shell 55, and the second spur gear 64 is driven to rotate by the second rotating rod 62 at the same time. Since the semi-spur gear ring 56 is fixed, the second spur gear 64 is driven by the outer wall teeth of the semi-spur gear ring 56 to drive the first large bevel gear 63 to rotate through the second rotating rod 62.
