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

Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe the technical content.

[0025] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may 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 barrel 1, which comprises: a cylindrical barrel body 11 and a conical barrel bottom 12, and a heat-insulating sleeve 13 arranged on the outer periphery of the barrel body 11 and connected to the barrel bottom 12; a material blocking mechanism 2, located at the bottom of the barrel body 11 to separate the barrel body 11 from the barrel bottom 12; a stirring component 3, one end of which extends into the barrel body 11; a cylinder 4, connected to the heat-insulating sleeve 13; wherein before stirring, the barrel bottom 12 abuts against the material blocking mechanism 2 to make the blocking mechanism The baffles 21 in the material mechanism 2 close the blanking channel 121, that is, the material is blocked in the barrel body 11 above the material blocking mechanism 2; when discharging, the cylinder 4 is suitable for adjusting the descending distance of the barrel bottom 12 through the heat-insulating sleeve 13, so that the baffles 21 in the material blocking mechanism 2 adjust the opening of the blanking channel 121, that is, the material in the barrel body 11 is discharged from the barrel bottom 12; when blocking the material, the cylinder 4 is suitable for driving the barrel bottom 12 to reset and move, and closing the baffles 21 in the material blocking mechanism 2 to squeeze the material out of the barrel bottom 12.

[0027] Specifically, such as Figure 2 As shown, when feeding, the barrel bottom 12 and the baffles 21 in the material blocking mechanism 2 are abutted against each other, so that each baffle 21 is in a state of closing the material drop channel 121. At this time, the materials fed into the mixing barrel 1 are all located in the barrel body 11, and then the materials in the barrel body 11 are stirred by the stirring component 3; wherein, since the bottom of the barrel body 11 is flat, the stirring component 3 can stir the materials located at the bottom of the barrel, and there will be no situation where the conical bottom causes the materials to be unable to be stirred.

[0028] Specifically, such as Figure 3 As shown, when the mixing is completed, the cylinder 4 drives the barrel bottom 12 to drop to a certain height, so that the baffles 21 in the blocking mechanism 2 move outward to open the material drop channel 121. At this time, the material in the barrel body 11 can be quickly discharged from the conical barrel bottom 12; wherein, the cylinder 4 can adjust the dropping speed by adjusting the descending distance of the barrel bottom 12.

[0029] Specifically, when the material is blocked, the cylinder 4 drives the barrel bottom 12 to reset and move and closes the baffles 21 in the blocking mechanism 2. At this time, the space below the baffles 21 is reduced, and at the same time, the material part located between the baffles 21 is squeezed into the barrel bottom 12, thereby squeezing the material blocked in the barrel bottom 12 out of the barrel bottom 12.

[0030] Specifically, the heat-insulating sleeve 13 can keep the material in the barrel body 11 after low-temperature treatment warm, and prevent the material from thermal decomposition by reducing the heating rate of the material.

[0031] In this embodiment, a material blocking mechanism 2 is provided at the bottom of the barrel body 11, so that each baffle 21 in the material blocking mechanism 2 closes the material drop channel 121 to form a flat bottom before stirring, thereby facilitating the stirring assembly 3 to stir all the materials; and each baffle 21 in the material blocking mechanism 2 opens the material drop channel 121 when discharging the materials, so that the materials in the barrel body 11 are quickly discharged from the conical barrel bottom 12; and when the materials are blocked, the barrel bottom 12 is reset to move to squeeze the materials in the barrel bottom 12 to prevent blocking.

[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 together to close the material blanking channel 121 .

[0033] In this embodiment, before stirring, the baffles 21 are closed together to block the material drop channel 121 at the bottom of the barrel body 11. At this time, the mixing barrel 1 has a flat bottom, which prevents 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 body 11; wherein, the guide block 22 is slidably set in the guide groove 111, and the guide block 22 and the guide groove 111 are connected by a spring 23; when discharging, the barrel bottom 12 is suitable for lowering 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 blanking channel 121 by sliding the guide block 22 in the guide groove 111; wherein, when the baffle 21 is in the state of closing the blanking channel 121, the spring 23 is in a stretched state, so when the bottom of the barrel 12 drops in height, the stretched spring 23 will reset and pull the baffle 21 outward.

[0036] like Figure 4As shown, in some embodiments, a first guide slope 211 is provided on the lower surface of the baffle 21; a second guide slope 122 is provided on the upper surface of the barrel bottom 12; the second guide slope 122 is adapted to the first guide slope 211; when discharging, 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 to move outward.

[0037] In this embodiment, the existence of the guiding slope makes it easier for the barrel bottom 12 to push the baffle 21 to close and move during the upward movement.

[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 heat-insulating sleeve 13 .

[0039] In this embodiment, the function of the heat-insulating sleeve 13 is to reduce the temperature rise rate of the material after low-temperature treatment, that is, to prevent thermal decomposition of the material.

[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 is passed through the barrel cover 14 of the stirring barrel 1, and one end thereof extends into the barrel body 11; the stirring paddle 33 is arranged on the stirring shaft 32; the motor 31 is arranged on the barrel cover 14 and is 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 into a stirring tank 1 and stirring; performing sedimentation treatment after the stirring is completed; sending the supernatant liquid after the sedimentation treatment in the stirring tank 1 to a reactor; stirring the supernatant liquid in the reactor, and injecting hydrofluoric acid into the reactor until the pH is neutral; centrifuging the reaction liquid in the reactor to achieve solid-liquid separation; sending the solid in the reactor to a dryer for drying, and sending the liquid in the reactor to a liquid storage tank.

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

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

[0044] Specifically, when feeding, the barrel bottom 12 is against the baffles 21 in the baffle mechanism 2, so that the baffles 21 are in a state of closing the material drop channel 121. At this time, the materials fed into the mixing barrel 1 are all located in the barrel body 11, and then the materials in the barrel body 11 are stirred by the stirring component 3; wherein, since the bottom of the barrel body 11 is flat, the stirring component 3 can stir the materials at the bottom of the barrel, and there will be no situation where the materials cannot be stirred due to the conical bottom.

[0045] Specifically, when the stirring is completed, the cylinder 4 drives the barrel bottom 12 to drop to a certain height, so that the baffles 21 in the blocking mechanism 2 expand outward to open the material drop channel 121. At this time, the material in the barrel body 11 can be discharged quickly; at the same time, the cylinder 4 adjusts the descending distance of the barrel bottom 12 to achieve the adjustment of the material drop speed.

[0046] In some embodiments, the lithium carbonate raw material is first subjected to low-temperature treatment and then put into the stirring tank 1.

[0047] In some embodiments, a heat-insulating sleeve 13 is provided on the periphery of the stirring tank 1 to prevent thermal decomposition of the lithium carbonate in the stirring tank 1 .

[0048] Specifically, due to the presence of the heat-insulating sleeve 13 , the heat-insulating sleeve 13 can keep the material in the barrel body 11 after low-temperature treatment warm, thereby preventing thermal decomposition of the material.

[0049] In summary, the lithium fluoride feeding device and its production process are achieved by setting a material blocking mechanism 2 at the bottom of the barrel body 11, so that each baffle 21 in the material blocking mechanism 2 closes the material drop channel 121 to form a flat bottom before stirring, thereby facilitating the stirring component 3 to stir all the materials, and enabling each baffle 21 in the material blocking mechanism 2 to open the material drop channel 121 when discharging the materials, thereby facilitating the discharge of the materials from the barrel body 11.
