Description

Technical Field

[0001] This invention belongs to the field of stirring technology, specifically relating to the stirring of lithium fluoride, and more particularly to a lithium fluoride feeding device and its production process. Background Technology

[0002] Existing feeding devices typically feed materials into a mixing tank with a flat bottom, allowing the materials to be mixed before feeding. However, this type of mixing tank with a flat bottom makes discharging difficult.

[0003] In related technologies, to solve the material discharge problem, the bottom of the mixing tank is set to be conical; however, setting the bottom of the mixing tank to be conical makes it difficult for the material inside the conical part to be stirred, resulting in uneven mixing of the material in that area.

[0004] Therefore, how to solve the technical problem that the material inside the cone-shaped part of the existing mixing tank with a cone-shaped bottom is difficult to be stirred during the stirring process is a problem that urgently needs to be solved by those skilled in the art.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0006] This disclosure provides at least one lithium fluoride feeding device and its production process.

[0008] In one alternative embodiment, the material blocking mechanism includes: a plurality of baffles; wherein each of the baffles is adapted to form a circle when closed to close the material discharge channel.

[0009] In one optional embodiment, a guide block is provided on the outer side of the baffle; a guide groove is provided on the inner wall of the barrel; the guide block is slidably disposed in the guide groove, and the guide block and the guide groove are connected by a spring; during discharge, the bottom of the barrel is adapted to lower so that the corresponding spring pulls the corresponding baffle to move outward to open the discharge channel.

[0010] In one optional embodiment, the lower surface of the baffle is provided with a first guide slope; the upper surface of the barrel bottom is provided with a second guide slope; the second guide slope is adapted to the first guide slope; during discharge, the second guide slope of the barrel bottom is adapted to descend, causing the corresponding spring to pull the corresponding baffle outward.

[0011] In one alternative embodiment, the cylinder is mounted on the side wall of the barrel, and its drive end is connected to the insulation sleeve.

[0012] In one optional embodiment, the stirring assembly includes: a motor, a stirring shaft, and a stirring paddle; the stirring shaft passes through the lid of the stirring tank, and one end of it extends into the tank body; the stirring paddle is disposed on the stirring shaft; the motor is disposed on the lid and connected to the stirring shaft.

[0013] Secondly, this disclosure also provides a production process for a lithium fluoride feeding device, comprising: adding ultrapure water and lithium carbonate to a stirring tank and stirring; performing sedimentation treatment after stirring; sending the supernatant after sedimentation treatment in the stirring tank to a reaction vessel; stirring the supernatant in the reaction vessel while injecting hydrofluoric acid into the reaction vessel until the pH is neutral; centrifuging the reaction liquid in the reaction vessel to achieve solid-liquid separation; sending the solid in the reaction vessel to a dryer for drying treatment; and sending the liquid in the reaction vessel to a liquid storage tank.

[0014] In one optional embodiment, the baffle mechanism inside the mixing tank is in a closed state when the mixing tank is mixing; and in an open state when the mixing tank is discharging material.

[0015] In one alternative embodiment, the lithium carbonate raw material is first subjected to low-temperature treatment before being added to the mixing tank.

[0016] In one alternative embodiment, an insulating sleeve is provided around the mixing tank to prevent the thermal decomposition of lithium carbonate inside the mixing tank.

[0017] The beneficial effects of this invention are that the lithium fluoride feeding device and its production process are achieved by setting a baffle mechanism at the bottom of the barrel, so that each baffle in the baffle mechanism closes the material discharge channel before stirring to form a flat bottom, thereby facilitating the stirring component to stir all materials, and by setting each baffle in the baffle mechanism to open the material discharge channel during material discharge, thereby facilitating the material discharge from the barrel.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figures 1 to 3 As shown, at least one embodiment provides a lithium fluoride feeding device, comprising: a stirring tank 1, which includes: a cylindrical tank body 11 and a conical tank bottom 12, and an insulating sleeve 13 fitted around the tank body 11 and connected to the tank bottom 12; a baffle mechanism 2, located at the bottom of the tank body 11 to separate the tank body 11 from the tank bottom 12; a stirring assembly 3, one end of which extends into the tank body 11; and a cylinder 4 connected to the insulating sleeve 13; wherein before stirring, the tank bottom 12 abuts against the baffle mechanism 2 to prevent the baffle from being stirred. The baffles 21 in the material feeding mechanism 2 close the material discharge channel 121, thus blocking the material in the barrel body 11 above the material feeding mechanism 2. During discharge, the cylinder 4 is adapted to adjust the descent distance of the barrel bottom 12 through the heat insulation sleeve 13, so that the baffles 21 in the material feeding mechanism 2 adjust the opening of the material discharge channel 121, that is, the material in the barrel body 11 is discharged from the barrel bottom 12. During blockage, the cylinder 4 is adapted to drive the barrel bottom 12 to reset and move, and to close the baffles 21 in the material feeding mechanism 2 so that the material is squeezed out of the barrel bottom 12.

[0027] Specifically, such as Figure 2 As shown, during feeding, the bottom 12 of the bucket abuts against each baffle 21 in the material blocking mechanism 2, so that each baffle 21 is in the closed material discharge channel 121 state. At this time, the material fed into the mixing bucket 1 is located in the bucket body 11. Then, the mixing component 3 mixes the material in the bucket body 11. Since the bottom of the bucket body 11 is flat, the mixing component 3 can mix the material located at the bottom of the bucket, and there will be no situation where the material cannot be mixed due to the conical bottom.

[0028] Specifically, such as Figure 3 As shown, after the mixing is completed, the cylinder 4 drives the bottom 12 of the barrel to drop a certain height, causing the baffles 21 in the baffle mechanism 2 to move outward and open the material discharge channel 121. At this time, the material in the barrel body 11 can be quickly discharged from the cone-shaped bottom 12 of the barrel. The cylinder 4 can adjust the material discharge speed by adjusting the descent distance of the bottom 12 of the barrel.

[0029] Specifically, when material blockage occurs, the cylinder 4 drives the barrel bottom 12 to reset and move, causing each baffle 21 in the material blocking mechanism 2 to close. At this time, the space below the baffle 21 is reduced, and the material located between each baffle 21 is squeezed into the barrel bottom 12, thereby squeezing out the material blocking the barrel bottom 12.

[0030] Specifically, the insulation sleeve 13 can keep the material inside the barrel 11 after it has been treated at low temperature, and prevent the material from thermally decomposing by reducing the heating rate of the material.

[0031] In this embodiment, by providing a baffle mechanism 2 at the bottom of the barrel 11, each baffle 21 in the baffle mechanism 2 closes the discharge channel 121 before stirring to form a flat bottom, thereby facilitating the stirring assembly 3 to stir all materials; and each baffle 21 in the baffle mechanism 2 opens the discharge channel 121 during discharge, so that the material in the barrel 11 can be quickly discharged from the conical barrel bottom 12; and in case of blockage, the material in the barrel bottom 12 is squeezed by the reset movement of the barrel bottom 12 to prevent blockage.

[0032] In some embodiments, the material blocking mechanism 2 includes: a plurality of baffles 21; wherein each baffle 21 is adapted to form a circle when closed to close the material discharge channel 121.

[0033] In this embodiment, before stirring, each baffle 21 is brought together to block the material discharge channel 121 at the bottom of the barrel 11. At this time, the stirring barrel 1 has a flat bottom, which avoids the material from accumulating in the conical barrel bottom 12.

[0034] like Figure 4 As shown, in some embodiments, a guide block 22 is provided on the outer wall of the baffle 21, and a guide groove 111 is provided on the inner wall of the barrel 11; wherein, the guide block 22 is slidably disposed in the guide groove 111, and the guide block 22 and the guide groove 111 are connected by a spring 23; during discharge, the bottom of the barrel 12 is adapted to lower the height so that the corresponding spring 23 pulls the corresponding baffle 21 outward to open the discharge channel 121.

[0035] In this embodiment, the baffle 21 opens and closes the material discharge channel 121 by sliding the guide block 22 in the guide groove 111; wherein, when the baffle 21 is in the closed material discharge channel 121, the spring 23 is in the stretched state, so when the bottom of the barrel 12 drops, the stretched spring 23 will reset and pull the baffle 21 outward.

[0036] like Figure 4As shown, in some embodiments, the lower surface of the baffle 21 is provided with a first guide slope 211; the upper surface of the barrel bottom 12 is provided with a second guide slope 122; the second guide slope 122 is adapted to the first guide slope 211; during discharge, the second guide slope 122 of the barrel bottom 12 is adapted to descend, so that the corresponding spring 23 pulls the corresponding baffle 21 outward.

[0037] In this embodiment, the presence of the guide ramp makes it easier to push the baffle 21 to close and move during the upward movement of the barrel bottom 12.

[0038] In some embodiments, the cylinder 4 is disposed on the side wall of the barrel body 11, and its driving end is connected to the insulation sleeve 13.

[0039] In this embodiment, the function of the heat insulation sleeve 13 is to reduce the heating rate of the material after low-temperature treatment, that is, to prevent the material from thermally decomposing.

[0040] like Figure 2 As shown, in some embodiments, the stirring assembly 3 includes: a motor 31, a stirring shaft 32, and a stirring paddle 33; the stirring shaft 32 passes through the lid 14 of the stirring tank 1, and one end of it extends into the tank body 11; the stirring paddle 33 is disposed on the stirring shaft 32; the motor 31 is disposed on the lid 14 and connected to the stirring shaft 32.

[0041] At least one embodiment also provides a production process for a lithium fluoride feeding device, comprising: adding ultrapure water and lithium carbonate to a stirring tank 1 and stirring; performing sedimentation treatment after stirring; sending the supernatant after sedimentation treatment in the stirring tank 1 to a reaction vessel; stirring the supernatant in the reaction vessel while injecting hydrofluoric acid into the reaction vessel until the pH is neutral; centrifuging the reaction liquid in the reaction vessel to achieve solid-liquid separation; sending the solid in the reaction vessel to a dryer for drying treatment; and sending the liquid in the reaction vessel to a liquid storage tank.

[0042] For the specific structure and implementation process of the lithium fluoride feeding device, please refer to the relevant discussion in the above embodiments, which will not be repeated here.

[0043] In some embodiments, when the mixing tank 1 is mixing, the baffle mechanism 2 inside the mixing tank 1 is in a closed state; when the mixing tank 1 is discharging material, the baffle mechanism 2 inside the mixing tank 1 is in an open state.

[0044] Specifically, during feeding, the bottom 12 of the bucket abuts against each baffle 21 in the material blocking mechanism 2, so that each baffle 21 is in the closed material discharge channel 121 state. At this time, the material fed into the mixing bucket 1 is located in the bucket body 11. Then, the mixing component 3 mixes the material in the bucket body 11. Since the bottom of the bucket body 11 is flat, the mixing component 3 can mix the material located at the bottom of the bucket, and there will be no situation where the material cannot be mixed due to the conical bottom.

[0045] Specifically, after mixing is completed, the cylinder 4 drives the bottom 12 of the barrel to descend a certain height, causing the baffles 21 in the baffle mechanism 2 to expand outward and open the material discharge channel 121, at which time the material in the barrel 11 can be discharged quickly; at the same time, the cylinder 4 adjusts the descent distance of the bottom 12 of the barrel to adjust the material discharge speed.

[0046] In some embodiments, the lithium carbonate raw material is first subjected to low-temperature treatment before being added to the mixing tank 1.

[0047] In some embodiments, an insulating sleeve 13 is provided around the stirring tank 1 to prevent the thermal decomposition of lithium carbonate inside the stirring tank 1.

[0048] Specifically, due to the presence of the insulation sleeve 13, the insulation sleeve 13 can keep the material inside the barrel 11 after low-temperature treatment warm, thereby preventing the material from thermally decomposing.

[0049] In summary, this lithium fluoride feeding device and its production process, by setting a baffle mechanism 2 at the bottom of the barrel 11, allows each baffle 21 in the baffle mechanism 2 to close the material discharge channel 121 before stirring to form a flat bottom, thereby facilitating the stirring component 3 to stir all materials, and allows each baffle 21 in the baffle mechanism 2 to open the material discharge channel 121 during material discharge, thereby facilitating the discharge of materials from the barrel 11.
