Description

Technical Field

[0001] The utility model relates to the technical field of lithium carbonate production and processing, in particular to a heating type centrifugal separator for producing lithium carbonate. Background Art

[0002] Lithium is known as the "energy metal of the 21st century" due to its special properties. Lithium and its compounds are called "industrial MSG", and their product uses span the lithium industry chain of multiple cutting-edge industries. Lithium and its compounds are mainly derived from the extraction of lithium ore and salt lake lithium resources. As one of the basic lithium salt products, lithium carbonate is divided into three categories by domestic enterprises according to existing product standards: industrial-grade lithium carbonate (main content <99.50%), battery-grade lithium carbonate (99.50%≤content <99.99%) and high-purity lithium carbonate (main content ≥99.99%). They are mainly used in ceramics, glass, atomic energy, aerospace, lithium batteries, lithium alloys, medicine and other fields.

[0003] In the lithium carbonate production process, the raw materials react in the reactor to form a mixture containing lithium carbonate and liquid. However, the existing separation devices have some problems in separating the solid and liquid of this mixture: the operation is complicated and the efficiency is low. Since the mixture of lithium carbonate and liquid is easy to agglomerate in the separation device, the difficulty of solid-liquid separation increases, which in turn affects the separation effect of the device on the raw materials.

[0009] The technical effect of adopting the above further solution is: the liquid flows out of the interior of the separation barrel through the discharge pipe.

[0010] As a preferred embodiment, a one-way valve is fixedly installed inside the discharge pipe and close to the bottom of the separation barrel, and three support columns are fixedly installed at the bottom of the separation barrel.

[0011] The technical effect of adopting the above further solution is: the setting of the support column can support the entire device, making the device run more smoothly.

[0012] As a preferred embodiment, a barrel cover is movably connected to the top outer surface of the separation barrel, and a second rotating shaft is movably embedded in the inner center of the barrel cover.

[0019] The technical effect of adopting the above further solution is: the separation barrel is heated by the heating rod.

[0020] Compared with the prior art, the advantages and positive effects of the utility model are:

[0021] 1.

A sieve barrel 107 is fixedly installed on the top of the shaft 102, and a plurality of slots 108 are opened inside the sieve barrel 107. Slide grooves 109 are opened at the centers of both sides of the inner wall of the sieve barrel 107, and a sieve basket 110 is movably embedded inside the sieve barrel 107. Slide blocks 111 are fixedly installed at the centers of both sides of the sieve basket 110, and the outer surfaces of the two slide blocks 111 are slidably connected to the inner surfaces of the slide grooves 109. A discharge pipe 112 is fixedly installed at the center of the bottom of the separation barrel 1, and a one-way valve 113 is fixedly installed inside the discharge pipe 112 and near the bottom of the separation barrel 1, and three support columns 114 are fixedly installed at the bottom of the separation barrel 1, and a barrel cover 2 is movably connected to the outer surface of the top of the separation barrel 1, and a heating rod 205 is fixedly embedded on the left side of the barrel cover 2 and inside the separation barrel 1.

[0031] In this embodiment, the staff can first pick up the screen basket 110, make the slider 111 first embedded in the inner surface of the slide groove 109, and then continue to press the screen basket 110, drive the slider 111 to slide on the inner surface of the slide groove 109, so that the screen basket 110 is embedded in the inside of the screen barrel 107, and then cover the separation barrel 1 with the barrel cover 2, and then put the raw material into the screen basket 110 through the feed pipe 204. After the raw material is put in, the first motor 105 is turned on through the power supply system of the first motor 105 of the support plate 104, so that the first When the motor 105 is running, it is transmitted to the first bevel gear 103 through the second bevel gear 106, thereby driving the first rotating shaft 102 embedded in the connecting plate 101 to rotate, and when the first rotating shaft 102 rotates, it drives the screen barrel 107 to rotate, so that the screen basket 110 rotates synchronously, and then the liquid contained in the raw material inside the screen basket 110 is thrown out of the screen basket 110 through the centrifugal force, and then thrown out of the screen barrel 107 through the notch 108, so as to separate the raw material into solid and liquid.

When the raw materials are put in, the power supply system of the first motor 105 of the support plate 104 is turned on to make the first motor 105 When the machine 105 is running, the second bevel gear 106 transmits the transmission to the first bevel gear 103, thereby driving the first rotating shaft 102 embedded in the connecting plate 101 to rotate, and when the first rotating shaft 102 rotates, it drives the screen barrel 107 to rotate, so that the screen basket 110 rotates synchronously, and then the liquid contained in the raw material inside the screen basket 110 is thrown out of the screen basket 110 through the centrifugal force, and then thrown out of the screen barrel 107 through the notch 108, so as to separate the raw material into solid and liquid. During separation, the heating rod 205 is turned on through the power supply system of the heating rod 205, and then the separation barrel 1 is heated by the heating rod 205, so that the raw materials can be prevented from agglomerating when the raw materials are separated, thereby affecting the separation effect. After the liquid separation is completed, the one-way valve 113 is opened again to allow the liquid to flow out of the interior of the separation barrel 1 through the discharge pipe 112. Through the first motor 105, the screen barrel 107, the heating rod 205 and other structures, the device forms a relatively closed device when separating the raw materials, making the separation process more concentrated and coherent, and being able to quickly separate solids and liquids to improve the separation efficiency. At the same time, heating the separation barrel 1 can increase the solubility of the raw materials, prevent the raw materials from agglomerating, and improve the separation effect. Through the setting of the support column 114, the entire device can be supported, making the device run more smoothly. Through the setting of the slider 111 and the slide 109, it can be prevented that when the screen barrel 107 drives the screen basket 110 to rotate, the screen basket 110 is prevented from rotating and bumping inside the screen barrel 107, thereby affecting the use of the structure. During use, when the screen basket 110 is rotating and separating, the staff can turn on the second motor 203 through the power supply system of the second motor 203, so that the second motor 203 drives the paddle 202 to rotate inside the screen basket 110 through the second rotating shaft 201 when rotating, thereby stirring the raw materials inside the screen basket 110, and through the linkage structure such as the second motor 203 and the paddle 202, the screen basket 110 can stir the raw materials when separating the raw materials, preventing the raw materials from adhering to the inner wall of the screen basket 110 during the rotational separation of the raw materials, resulting in incomplete separation, and further increasing the separation effect of the device (it should be noted that the first motor 105 and the second motor 203 are model Y90S-4, with a power of 1.1KW).
