Description

Technical Field

[0001] This utility model relates to the field of hydrometallurgical technology, specifically a continuous saponification device in a continuous extraction process. Background Technology

[0002] A continuous saponification unit is an industrial device used for continuous saponification reactions. Simply put, saponification is the process by which oils or fats react with an alkali (usually sodium hydroxide or potassium hydroxide) to produce soap and glycerin.

[0003] For example, the patent with authorization announcement number CN219059077U describes a continuous saponification device in a continuous extraction process. The described scheme is as follows: a saponification tank is set up so that the organic and sodium hydroxide solution after P204 washing are continuously added into the saponification tank through a flow meter. After the concentration of hydrogen ions in the post-saponification organic meets the requirements of the extraction process, the post-saponification organic is gradually released into the mixing chamber, thereby realizing the continuous and stable flow of post-saponification organic into the next process. The operation is simple, easy to carry out continuous production on site, and conducive to the stable operation of the extraction box.

[0004] The aforementioned technology has the drawback that, when using a continuous saponification unit, unreacted raw materials, byproducts, or other impurities may remain in the material after the reaction is complete. If these impurities are discharged directly without treatment, they may adversely affect subsequent process flows. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-4As shown, a continuous saponification device in a continuous extraction process includes: a protective enclosure 100, a saponification tank 200, a mixing tank 300, and a stirring assembly for stirring liquids. The saponification tank 200 is installed on one side of the inner bottom wall of the protective enclosure 100, and the mixing tank 300 is installed on the other side of the inner bottom wall of the protective enclosure 100. The stirring assembly includes two motors 401, which are respectively installed on the top of the saponification tank 200 and the mixing tank 300. A stirring shaft 402 is installed at the output end of the motor 401, and stirring blades 403 are installed on the outer wall of the stirring shaft 402. A liquid inlet pipe 404 is connected to one side of the top of the saponification tank 200, and a liquid drain pipe 405 is connected to the bottom of the mixing tank 300. By starting the two motors 401 respectively, the two stirring shafts 402 are driven to rotate, thereby driving the two stirring blades 403 to rotate, thus effectively mixing the materials and ensuring a more thorough reaction.

[0031] The saponification tank 200 is equipped with a monitoring component for monitoring the liquid level.

[0032] The drain pipe 405 is equipped with a filter assembly for filtering impurities.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the monitoring component includes 501. The cross-shaped sliding groove 501 is opened on one side inside the saponification tank 200. 502 is slidably connected inside the cross-shaped sliding groove 501. 503 is installed on one side of the cross-shaped sliding block 502. A blocking block 504 is installed on the top of the floating block 503. 505 is slidably connected to the top of the saponification tank 200. 504 is movably abutted against the bottom end of the sliding column 505. When the liquid level rises, the floating block 503 drives the cross-shaped sliding block 502 to slide upwards in the cross-shaped sliding groove 501. When the liquid level falls, the floating block 503 and the cross-shaped sliding block 502 slide downwards. The blocking block 504 on the top of the floating block 503 moves up and down with the movement of the floating block 503. When the liquid level rises to a certain height, the blocking block 504 abuts against the bottom end of the sliding column 505. The state of the sliding column 505 can be observed to determine whether the liquid level has reached the upper limit, thus serving as a liquid level warning.

[0034] In one embodiment, such as Figure 2 and Figure 4As shown, the filter assembly includes 601. The filter box 601 is installed at the bottom end of the drain pipe 405. 602 is slidably connected inside the filter box 601. 603 is installed on one side of the filter plate 602. 604 is installed at both ends of the side cover 603 near the filter plate 602. An iron block is installed on one side of the filter box 601. The side cover 603 movably abuts against the filter box 601. The magnetic block 604 attracts the iron block, causing the side cover 603 to tightly abut against the filter box 601, fixing the filter plate 602. When it is necessary to clean or replace the filter plate 602, the side cover 603 is opened, and the filter plate 602 is pulled out for operation.

[0035] In one embodiment, such as Figure 1 and Figure 3 As shown, both the saponification tank 200 and the mixing tank 300 are equipped with a breather valve 601 on their tops; used to balance the air pressure inside the saponification tank 200 and the mixing tank 300.

[0036] In one embodiment, such as Figure 2 As shown, the reflux assembly includes a first water pump 801, which is disposed on one side of the saponification tank 200. The discharge end of the first water pump 801 is connected to the saponification tank 200. A liquid outlet pipe 802 is connected to one side of the bottom of the saponification tank 200. A first reflux pipe 803 is connected to one side of the mixing tank 300. A three-way valve 804 is installed at one end of the liquid outlet pipe 802. A suction pipe 805 is connected to the suction end of the first water pump 801. Both the return pipe 803 and the suction pipe 805 are connected to the three-way valve 804. When reflux is required, the first water pump 801 is started and the liquid is drawn from the three-way valve 804 through the suction pipe 805. The liquid is then transported back to the saponification tank 200 through the discharge end. When the material in the mixing tank 300 has not completely reacted, the first water pump 801 is used to draw the liquid from the first return pipe 803 by switching the three-way valve 84, and the unreacted material is returned to the interior of the saponification tank 200.

[0037] In one embodiment, such as Figure 2 and Figure 3 As shown, a second water pump 901 is provided on one side of the saponification tank 200. The suction end of the second water pump 901 is connected to the saponification tank 200 through a pipe, and the discharge end of the second water pump 901 is connected to a second return pipe 902, which is connected to the mixing tank 300. The second water pump 901 can transport the liquid in the saponification tank 200 to the mixing tank 300.

[0038] In one embodiment, such as Figure 1 and Figure 3As shown, a scale line is provided on one side of the sliding column 505; the liquid level in the saponification tank can be read intuitively through the scale line, which makes it convenient for operators to accurately grasp the liquid level information, adjust the liquid inlet in time, and ensure the stable operation of the device.

[0039] The above embodiment discloses a continuous saponification device in a continuous extraction process. In operation, the liquid required for the reaction is injected into the saponification tank 200 through the inlet pipe 404. Then, two motors 401 are started, driving two stirring shafts 402 to rotate, which in turn drives two stirring blades 403 to rotate, effectively mixing the materials and ensuring a more thorough reaction. A monitoring component monitors the liquid level to ensure that the liquid in the saponification tank 200 does not exceed a preset range. When the liquid level rises, the float block 503 drives the cross-sliding block 502 to slide upwards within the cross-sliding groove 501. When the liquid level falls, the float block 503 and the cross-sliding block 502 slide downwards. The block 504 at the top of the float block 503 moves up and down with the movement of the float block 503. When the liquid level rises to a certain height, the block 504 abuts against the bottom of the sliding column 505. The liquid level is determined by observing the state of the sliding column 505, which serves as a liquid level warning. When backflow is required, the first water pump 801 is started, and liquid is drawn from the three-way valve 804 through the suction pipe 805. The liquid is then transported back to the saponification tank 200 through the discharge end. When the material in the mixing tank 300 has not completely reacted, the first water pump 801 is used to draw liquid from the first return pipe 803 by switching the three-way valve 804, and the unreacted material is returned to the inside of the saponification tank 200. When the liquid in the mixing tank 300 is discharged, impurities are filtered by the filter plate 604. The magnetic block 604 and the iron block attract each other, so that the side cover 603 is tightly abutted against the filter box 601, fixing the filter plate 602. When the filter plate 602 needs to be cleaned or replaced, the side cover 603 is opened and the filter plate 602 is pulled out for operation.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
