Description

Technical Field

[0001] This utility model relates to the field of solvent extraction equipment technology, and more specifically, to a high-efficiency solvent extraction equipment. Background Technology

[0002] Desolvation refers to the phenomenon in which solute atoms in a supersaturated solid solution agglomerate and precipitate a new phase. A desolvation vessel is required in the desolvation process.

[0003] Existing solvent extraction vessels require stirring and heating to accelerate solvent evaporation during solvent extraction, so that pure solid substances can precipitate and crystallize. However, due to the limited distribution and heating range of traditional heating structures, the heating uniformity of materials in the solvent extraction vessel is poor, resulting in unsatisfactory solvent evaporation and thus reducing solvent extraction efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a high-efficiency solvent removal vessel, which has the advantage of improving the solvent evaporation effect, thereby solving the problems in the background art mentioned above.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned advantages in improving solvent evaporation, the specific technical solution adopted by this utility model is as follows: A high-efficiency solvent extraction vessel includes a vessel body. A motor is fixed to the top of the vessel body, and a stirring paddle is fixed to the output end of the motor via a coupling. Several stirring rods are fixed to the lower part of the stirring paddle extending into the vessel body, and several hollow discs are welded equidistantly to the surface of each stirring rod. An annular groove is formed on the lower surface of the vessel body shell, and several electric heating elements are fitted into the inner side of the annular groove. Several openings are formed through the annular groove on the lower surface of the vessel body shell, and an arc-shaped cover plate is fixed to the inner side of each opening by screws. A feed nozzle is provided on the left side of the top surface of the vessel body, and a liquid inlet pipe is connected to the right side of the top surface of the vessel body. An air inlet pipe is inserted through the surface of the liquid inlet pipe of the vessel body. A discharge nozzle is connected to the bottom of the vessel body, and a temperature controller electrically connected to the electric heating elements is installed on the upper surface of the vessel body shell. A temperature sensor electrically connected to the temperature controller is provided inside the annular groove, and the probe of the temperature sensor extends into the interior of the vessel body.

[0008] Furthermore, the surface of the air-filling pipe is provided with several connecting blocks that are connected to the inner wall of the vessel at equal intervals, and the lower surface of the flushing pipe is provided with several through holes.

[0009] Furthermore, each of the hollowed-out discs of the stirring rod has several circular holes on its surface.

[0010] Furthermore, the top surface of the vessel is connected to an exhaust port, and a pressure relief valve is installed on the surface of the exhaust port.

[0011] Furthermore, a mounting block is welded to the corresponding opening inside the annular groove, and the mounting block fits into the concave surface of the arc-shaped cover plate, and screws are fixed between the mounting block and the arc-shaped cover plate.

[0012] Furthermore, several of the electric heating elements are arranged around the inner side of the annular groove, and each electric heating element has an arc-shaped structure, and the concave surface of each electric heating element is in close contact with the inner side of the annular groove.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a highly efficient desolvation vessel with the following beneficial effects:

[0015] (1) In this utility model, an annular groove is provided on the lower surface of the outer shell of the vessel, and several electric heating elements are installed around the inner side of the annular groove. When the several electric heating elements connected in series in the annular groove are started, they cause the several electric heating elements to heat the solution in the vessel evenly. The constant temperature heating of the electric heating elements is achieved by the temperature controller and temperature sensor. Compared with the prior art, the use of several electric heating elements installed around the vessel, combined with the hollowed-out disk with several holes on the stirring rod, facilitates the full stirring of the solution while heating evenly, and accelerates the evaporation process of the solvent to the greatest extent, thereby improving the efficiency of the desolvation vessel.

[0016] (2) In this utility model, an air-filling pipe is inserted into the liquid inlet pipe and extends into the interior of the vessel. Since the air-filling pipe is installed in close contact with the inner wall of the vessel through the connecting block, and combined with the through hole opened on the lower surface of the air-filling pipe, as the inert gas is introduced into the air-filling pipe, the inert gas enters the solution in the vessel through several through holes of the air-filling pipe, which is used to accelerate the disturbance of the solution in the vessel. This increases the mixing efficiency of the substance to be desolvated and the solvent without reacting with the material. Moreover, the installation method of being built into the liquid inlet pipe eliminates the need to open holes in the outer shell of the vessel, which is beneficial to ensuring the sealing of the vessel.

[0024] According to an embodiment of the present invention, a highly efficient desolventizing vessel is provided.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3As shown, a high-efficiency desolvation vessel according to an embodiment of the present invention includes a vessel body 1. A motor 2 is fixed to the top of the vessel body 1, and a stirring paddle 4 is fixed to the output end of the motor 2 via a coupling. Several stirring rods 11 are fixed to the lower part of the stirring paddle 4 extending into the inner side of the vessel body 1, and several hollow discs 12 are welded to the surface of each stirring rod 11 at equal intervals. An annular groove 8 is formed on the lower surface of the outer shell of the vessel body 1, and several electric heating elements 9 are fitted to the inner side of the annular groove 8. Several openings are formed through the annular groove 8 on the lower surface of the outer shell of the vessel body 1, and an arc-shaped cover plate 10 is fixed to the inner side of each opening by screws. A feed nozzle 3 is provided on the left side of the top surface of the vessel body 1, and a liquid inlet pipe 5 is connected to the right side of the top surface of the vessel body 1. An air inlet pipe 7 is inserted through the surface of the liquid inlet pipe 5 of the vessel body 1. A discharge nozzle 13 is connected to the bottom of the vessel body 1, and the outer shell of the vessel body 1... A temperature controller 14 electrically connected to an electric heating element 9 is installed on the upper surface of the vessel. A temperature sensor 17 electrically connected to the temperature controller 14 is provided inside the annular groove 8, and the probe of the temperature sensor 17 extends into the interior of the vessel body 1. To ensure the heating range, two sets of electric heating elements 9 are arranged around the annular groove 8. The output end of the temperature controller 14 is electrically connected to the electric heating element 9. The ambient temperature is automatically sampled and monitored in real time by the temperature sensor 17, which facilitates temperature control. The principle of the temperature controller 14 is a known existing technology, and there are mature products available. Therefore, its principle will not be further explained. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices. Therefore, the control method and wiring arrangement will not be explained in detail.

[0026] In one embodiment, the surface of the air-filling pipe 7 is provided with a plurality of connecting blocks 18 that are connected to the inner wall of the vessel body 1 at equal intervals, and the lower surface of the flushing pipe is provided with a plurality of through holes 16. The connecting blocks 18 are provided so that the air-filling pipe 7 is in close contact with the inner wall of the vessel body 1, preventing the air-filling pipe 7 from interfering with the stirring rod 11.

[0027] In one embodiment, each of the perforated discs 12 of the stirring rod 11 has several circular holes on its surface. The perforated discs 12 increase the stirring area and facilitate the breaking up of clumps of material.

[0028] In one embodiment, the top surface of the vessel body 1 is connected to an exhaust nozzle 6, and a pressure relief valve is installed on the surface of the exhaust nozzle 6. The exhaust nozzle 6 and the pressure relief valve are configured to release pressure when the pressure in the vessel body 1 is too high.

[0029] In one embodiment, a mounting block 15 is welded to the opening inside the annular groove 8, and the mounting block 15 fits against the concave surface of the arc cover plate 10. Screws are fixed between the mounting block 15 and the arc cover plate 10. The mounting block 15 provides an installation structure for the arc cover plate 10.

[0030] In one embodiment, a plurality of electric heating elements 9 are arranged around the inner side of the annular groove 8, and each electric heating element 9 has an arc-shaped structure, and the concave surface of each electric heating element 9 is in close contact with the inner side of the annular groove 8. In order to maintain the uniform heating effect of the electric heating elements 9, the plurality of electric heating elements 9 are connected in series. When a single electric heating element 9 is damaged, the other electric heating elements 9 will not work, thus avoiding the phenomenon of uneven heating of the vessel body 1 caused by local heating.

[0031] Working principle: First, the substance to be desolvated and the solvent are injected into the vessel body 1 through the feed nozzle 3 and the liquid inlet pipe 5, respectively. Then, the motor 2 is started to drive the stirring paddle 4 at its output end to rotate, causing several stirring rods 11 mounted on the lower surface of the stirring paddle 4 to rotate. Several hollowed-out discs 12 welded to the surface of the stirring rods 11 break up any clumps of solution in the vessel body 1, ensuring a good stirring effect. During this process, as several electric heating elements 9 connected in series in the annular groove 8 are activated, they uniformly heat the solution in the vessel body 1. The electric heating element 9 is kept at a constant temperature by the temperature controller 14 and the temperature sensor 17. As the temperature rises, the solvent in the solution begins to evaporate. After the solvent is completely evaporated, the pure solid substance precipitates and crystallizes. At the same time, by connecting the gas filling pipe 7 to an external inert gas storage tank, the inert gas is introduced into the gas filling pipe 7 and enters the solution in the vessel 1 through several through holes 16 of the gas filling pipe 7. This is used to accelerate the disturbance of the solution in the vessel 1 and increase the mixing efficiency of the substance to be desolvated and the solvent without reacting with the material.
