Description

Technical Field

[0001] This application relates to the technical field of mother liquor recovery devices, specifically a quetiapine intermediate mother liquor recovery device. Background Technology

[0002] Currently, chemical companies generate a large amount of mother liquor during the preparation of reagents or products. In order to improve the utilization rate of mother liquor, it is necessary to recycle it. Traditional mother liquor recycling devices recycle mother liquor through recycling tanks.

[0003] An existing patent (publication number: CN221107999U) discloses a high-efficiency polycarboxylate mother liquor recovery device, including a base, a tank body fixedly connected to the upper ends of three supporting legs, a sliding groove on the upper end of the tank body, four sliding seats slidably connected to the tank body through the sliding groove, a cover plate fixedly connected to the upper ends of the four sliding seats, a connecting mechanism connected to the lower middle part of the cover plate via a bearing, a filter assembly provided on the upper part of the outer surface of the connecting mechanism, six slots of No. 1 on the upper part of the inner wall of the tank, a No. 1 gear fixedly connected to the outer surface of the cover plate, and a support fixedly connected to the upper right part of the outer surface of the tank. This utility model discloses a high-efficiency polycarboxylate mother liquor recovery device that can scrape off the polycarboxylate mother liquor adhering to the inner wall of the tank, the arc-shaped seats, the No. 1 filter plate, the No. 2 filter plate, and the cover plate, achieving efficient recovery, improving the polycarboxylate mother liquor recovery effect, and reducing the waste of polycarboxylate mother liquor.

[0004] Since quetiapine intermediate mother liquor is prone to crystallization when the temperature drops, and the aforementioned comparative documents do not include a corresponding structure to address this issue, the mother liquor is prone to crystallization. If the crystals remain in the recovery tank for a long time, it will cause blockage of the recovery tank and affect the subsequent flow of mother liquor. In order to reduce the probability of crystallization in quetiapine intermediate mother liquor, a quetiapine intermediate mother liquor recovery device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a quetiapine intermediate mother liquor recovery device, which can maintain a certain temperature in the collection pipe and collection box through circulating heating, thereby reducing the probability of crystallization in the mother liquor and avoiding affecting the subsequent flow of the mother liquor.

[0006] To achieve the above objectives, this application provides the following technical solution: a quetiapine intermediate mother liquor recovery device, comprising a collection box, a metal heat-conducting collection pipe, and a base plate. A heating mechanism is provided between the collection box and the metal heat-conducting collection pipe. The heating mechanism includes a heating chamber fixedly connected to the upper surface of the collection box and a heating rod installed at the top of the heating chamber, as well as a first liquid pump and a second liquid pump installed on one side of the heating chamber. A metal serpentine tube is sleeved on the outside of the metal heat-conducting collection pipe, and the two ends of the metal serpentine tube are respectively connected to the first liquid pump and the second liquid pump. A metal heat-conducting cylinder is connected to the bottom of the heating chamber and is located inside the collection box. A scraping mechanism is provided at the bottom of the collection box.

[0007] The scraping mechanism includes a servo motor fixedly connected to the bottom surface of the base plate. The output shaft of the servo motor passes through the base plate and is fixedly connected to a connecting rod. Two first wall scrapers and two second wall scrapers are fixedly connected to the upper surface of the connecting rod. The two first wall scrapers are adapted to the inner wall of the collection box, and the two second wall scrapers are adapted to the outer surface of the metal heat-conducting cylinder.

[0008] The above solution enables continuous heat preservation of the collection box and the metal heat-conducting collection pipe through a heating mechanism, ensuring that the temperature inside both the collection box and the metal heat-conducting collection pipe is higher than the crystallization temperature of the quetiapine intermediate mother liquor. This prevents crystallization of the quetiapine intermediate mother liquor during collection. The scraping mechanism can both agitate the mother liquor inside the collection box and scrape off the crystals adhering to the inner wall of the collection box and the surface of the metal heat-conducting cylinder, effectively preventing crystals from remaining inside the collection box for a long time and facilitating the flow and collection of the mother liquor.

[0009] Furthermore, the metal heat-conducting collection pipe is installed at the top of the collection box, and evenly distributed positioning bolts are provided between the collection box and the bottom plate. The bottom plate is installed on the bottom surface of the collection box by a number of positioning bolts.

[0010] The above solution allows for easy disassembly and assembly of the base plate by setting positioning bolts, and enables regular cleaning of the inside of the collection box.

[0011] Furthermore, the output end of the first liquid pump and the input end of the second liquid pump are both connected to the interior of the heating chamber.

[0012] By defining the relationship between the first liquid pump, the second liquid pump, and the heating tank, the hot water in the heating tank can be circulated and transported through the first and second liquid pumps in the metal serpentine tube. This allows the metal heat-conducting collection tube to maintain a certain temperature and prevents crystallization of the quetiapine intermediate mother liquor during the collection process.

[0013] Furthermore, a measuring bar is installed on the outer surface of the heating box, and the inner wall of the measuring bar is inlaid with transparent glass.

[0014] The above scheme allows for real-time monitoring of the water content inside the heating chamber by setting a range bar, facilitating timely replenishment of water.

[0015] Furthermore, a water inlet is installed at the top of the heating box, and a water outlet is installed on one side of the heating box.

[0016] The above solution allows for easy addition of water to the heating tank by setting up an inlet and an outlet, and also facilitates the drainage of water from the heating tank, which is beneficial for regularly replacing the water in the heating tank.

[0017] Furthermore, a drain outlet is installed on one side of the collection box, which is connected to the interior of the collection box, and a valve is installed inside the drain outlet.

[0018] The above scheme allows for the convenient centralized discharge of the quetiapine intermediate mother liquor collected in the collection tank by setting up a drain outlet and valve.

[0019] Furthermore, a controller is installed on the outer surface of the collection box, and the heating rod, the first liquid pump, the second liquid pump, and the servo motor are all electrically connected to the controller.

[0020] The above solution allows for convenient control of the various electrical components in the device by setting up a controller, thus optimizing the operation process.

[0021] Furthermore, four support columns are fixedly connected to the outer surface of the collection box, and each support column is provided with an anti-slip pad at its bottom.

[0022] The above-mentioned scheme improves the stability of the device by setting up support columns and anti-slip pads, enabling more stable collection of quetiapine intermediate mother liquor.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This quetiapine intermediate mother liquor recovery device continuously maintains the temperature of the collection tank and the metal heat-conducting collection pipe through a heating mechanism, ensuring that the temperature inside both the collection tank and the metal heat-conducting collection pipe is higher than the crystallization temperature of the quetiapine intermediate mother liquor. This prevents crystallization of the quetiapine intermediate mother liquor during collection. A scraping mechanism is also included to agitate the mother liquor inside the collection tank, preventing localized overcooling and crystallization, and to scrape away crystals adhering to the inner wall of the collection tank and the surface of the metal heat-conducting cylinder, preventing prolonged crystal retention and ensuring smooth flow and effective collection of the mother liquor. This design guarantees both temperature control and good fluidity of the mother liquor, effectively preventing crystal accumulation and optimizing the collection quality. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 4This embodiment of a quetiapine intermediate mother liquor recovery device includes a collection box 1, a metal heat-conducting collection pipe 2, and a base plate 3. The metal heat-conducting collection pipe 2 is installed at the top of the collection box 1. Evenly distributed positioning bolts 10 are provided between the collection box 1 and the base plate 3. The base plate 3 is installed on the bottom surface of the collection box 1 by several positioning bolts 10. The positioning bolts 10 facilitate the disassembly and assembly of the base plate 3 and enable regular cleaning of the inside of the collection box 1. A drain port 6 is installed on one side of the collection box 1 and is connected to the inside of the collection box 1. A valve 7 is installed inside the drain port 6. The drain port 6 and valve 7 facilitate the centralized discharge of the quetiapine intermediate mother liquor collected in the collection box 1. Four support columns 9 are fixedly connected to the outer surface of the collection box 1. Each support column 9 has an anti-slip pad at its bottom. The support columns 9 and anti-slip pads improve the stability of the device and enable more stable collection of the quetiapine intermediate mother liquor.

[0033] Please see Figure 2 , Figure 3 and Figure 4 A heating mechanism 4 is provided between the collection tank 1 and the metal heat-conducting collection pipe 2. The heating mechanism 4 includes a heating box 401 fixedly connected to the upper surface of the collection tank 1, a heating rod 402 installed at the top of the heating box 401, and a first liquid pump 403 and a second liquid pump 404 installed on one side of the heating box 401. The heating rod 402 can heat the water in the heating box 401 to maintain a certain temperature and prevent the mother liquor from crystallizing due to excessively low temperature during the collection process. A metal serpentine tube 405 is sleeved on the outside of the metal heat-conducting collection pipe 2. The two ends of the metal serpentine tube 405 are respectively connected to the first liquid pump 403 and the second liquid pump 404. The output end of the first liquid pump 403 and the input end of the second liquid pump 404 are both connected to the inside of the heating box 401. By defining the relationship between the first liquid pump 403, the second liquid pump 404, and the heating box 401, the hot water in the heating box 401 can be circulated and transported through the first liquid pump 403 and the second liquid pump 404 in the metal serpentine tube 405, so that the metal heat-conducting collection tube 2 can maintain a certain temperature and avoid crystallization when the quetiapine intermediate mother liquor flows in the metal heat-conducting collection tube 2. The bottom end of the heating box 401 is connected to a metal heat-conducting cylinder 406, which is located inside the collection box 1. By setting the metal heat-conducting cylinder 406, the mother liquor inside the collection box 1 can be easily exchanged with the metal heat-conducting cylinder 406, so that the mother liquor collected inside the collection box 1 can maintain a certain temperature and prevent a large amount of crystallization.

[0034] Please see Figure 2 , Figure 3 and Figure 4The heating chamber 401 has a measuring bar 407 installed on its outer surface. The inner wall of the measuring bar 407 is inlaid with transparent glass. By setting the measuring bar 407, the water content inside the heating chamber 401 can be monitored in real time, making it convenient to add water to the heating chamber 401 in a timely manner. The top of the heating chamber 401 is equipped with a water inlet 408, and the side of the heating chamber 401 is equipped with a water outlet 409. By setting the water inlet 408 and the water outlet 409, it is convenient to add water to the heating chamber 401 and also convenient to drain the water in the heating chamber 401, which is conducive to the regular replacement of the water in the heating chamber 401.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The bottom of the collection box 1 is equipped with a scraping mechanism 5. The scraping mechanism 5 includes a servo motor 501 fixedly connected to the bottom surface of the base plate 3. The output shaft of the servo motor 501 passes through the base plate 3 and is fixedly connected to a connecting rod 502. Two first scraping blades 503 and two second scraping blades 504 are fixedly connected to the upper surface of the connecting rod 502. The two first scraping blades 503 are adapted to the inner wall of the collection box 1, and the two second scraping blades 504 are adapted to the outer surface of the metal heat-conducting cylinder 406. When the servo motor 501 is started, it will drive the connecting rod 502 to rotate. The rotation of the connecting rod 502 will cause the two first scraping blades 503 and the two second scraping blades 504 to rotate. The rotation of the first scraping blades 503 will scrape the contents of the collection box 1. The crystals adhering to the wall are scraped off. The rotation of the second wall scraper 504 can scrape off the crystals adhering to the surface of the metal heat-conducting cylinder 406. At the same time, the rotation of the second wall scraper 504 and the first wall scraper 503 can agitate the mother liquor inside the collection tank 1, so that the mother liquor can exchange heat more comprehensively with the metal heat-conducting cylinder 406, and maintain a certain temperature in the collection tank 1. This effectively prevents the mother liquor from crystallizing in large quantities inside the collection tank 1. A controller 8 is installed on the outer surface of the collection tank 1. The heating rod 402, the first liquid pump 403, the second liquid pump 404 and the servo motor 501 are all electrically connected to the controller 8. By setting the controller 8, the operation of each electrical component in the device can be easily controlled, and the operation process is optimized.

[0036] In this embodiment, a quetiapine intermediate mother liquor recovery device can continuously keep the collection tank 1 and the metal heat-conducting collection pipe 2 warm through the heating mechanism 4, so that the temperature inside the collection tank 1 and the metal heat-conducting collection pipe 2 is higher than the crystallization temperature of the quetiapine intermediate mother liquor, thus avoiding crystallization of the quetiapine intermediate mother liquor during the collection process. By setting up a scraping mechanism 5, the mother liquor inside the collection tank 1 can be stirred, and the crystals attached to the inner wall of the collection tank 1 and the surface of the metal heat-conducting cylinder 406 can be scraped off, effectively preventing the crystals from remaining in the collection tank 1 for a long time, which is beneficial to the flow and collection of the mother liquor.

[0037] It should be noted that since the scraping mechanism 5 is installed on the base plate 3, the scraping mechanism 5 will be removed together when the base plate 3 is removed. This makes it convenient to clean the inside of the collection box 1 regularly and facilitates reuse.

[0038] The working principle of the above embodiment is as follows: the quetiapine intermediate mother liquor is injected into the collection tank 1 through the bottom plate 3 for collection. Then, by starting the heating rod 402, the water in the heating tank 401 and the metal heat-conducting cylinder 406 can be kept at a certain temperature. Then, the first liquid pump 403 and the second liquid pump 404 are started to circulate the hot water through the metal serpentine tube 405. This keeps the metal heat-conducting collection tube 2 at a certain temperature, preventing the quetiapine intermediate mother liquor from crystallizing during the collection process. The quetiapine intermediate mother liquor will be collected in the collection tank 1. Then, the servo motor 501 is started to rotate the two first wall scrapers 503 and the two second wall scrapers 504 through the connecting rod 502. The rotation of the 04 agitates the mother liquor collected inside the collection tank 1, allowing it to fully contact the metal heat-conducting cylinder 406, thereby increasing the temperature of the mother liquor and maintaining it at a certain temperature to prevent crystallization. At the same time, the rotation of the first scraper 503 and the second scraper 504 can also scrape off any crystals that accidentally crystallize on the inner wall of the collection tank 1 and the surface of the metal heat-conducting cylinder 406, allowing the crystals to mix with the mother liquor again and then be agitated to dissolve them. This effectively solves the problem of crystallization that easily occurs when the mother liquor temperature drops. The collected mother liquor can then be centrally transported through the drain port 6 and the valve 7. Finally, the bottom plate 3 can be removed from the bottom of the collection tank 1 using the positioning bolts 10, and the interior of the collection tank 1 can be cleaned periodically.
