Description

Technical Field

[0001] This utility model relates to the field of separation and purification equipment technology, specifically to a separation and purification equipment for avermectin production. Background Technology

[0002] Avermectin is a sixteen-membered macrocyclic lactone compound with insecticidal, acaricidal, and nematicidal activities, produced by the fermentation of Streptomyces griseus. It is mainly used as an agricultural insecticide, nematicide, and veterinary anthelmintic. The processing of avermectin generally involves mixing the raw materials and then performing a series of operations such as shaping and drying to form a complete agent. The raw materials are usually mixed with other substances. During extraction, separation and purification equipment is used to extract the required materials, generally by distillation, based on the different boiling points of the substances.

[0003] For example, Chinese patent CN216909171U discloses a separation and purification device for small molecule drug production, including a base. An insulation shell is fixedly connected to the upper surface of the base, and a heating component is installed at the bottom of the insulation shell. A holding container is detachably connected to the upper surface of the heating component, and a top cover is detachably connected to the upper surface of the holding container. A speed reducer is installed on the upper surface of the top cover. This separation and purification device for small molecule drug production, by incorporating a water tank, a high-pressure pump, a cleaning pipe, and a nozzle, forms a cleaning system. After use, the high-pressure pump draws water from the tank into the cleaning pipe, which is then sprayed onto the holding container by the nozzle for cleaning. This ensures the holding container remains clean and improves the overall effectiveness of the separation and purification device.

[0004] Although the aforementioned patent improves the effectiveness of the separation and purification device for small molecule drug production, the cleaning effect is generally limited due to the use of at least two nozzles to clean the inside of the container. Furthermore, substances adhering to the inner wall of the container may not be completely removed, thus reducing its practicality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a separation and purification device for avermectin production, which has advantages such as improved cleaning effect and cleaning efficiency. It solves the problem that cleaning the inside of the container using no fewer than two nozzles generally results in poor cleaning effect and may fail to remove substances adhering to the inner wall of the container, thus reducing its practicality.

The two scrapers are all located on the opposite sides of the left and right connecting rods, and the opposite sides of the left and right scrapers are in contact with the left and right side walls of the inner cavity of the tank. The two spray pipes are all connected to the left and right sides of the rotating pipe. The at least two nozzles are all connected to the lower surface of the left and right spray pipes. The water tank is located on the left side of the tank, and the high-pressure pump is located on the upper surface of the water tank.

[0009] By adopting this technical solution, the scrapers on the left and right sides can remove the waste materials adhering to the inner wall of the tank, thereby improving the cleaning effect and efficiency.

[0010] Furthermore, the connecting pipe is connected to the output end of the high-pressure pump, and the end of the connecting pipe away from the high-pressure pump is rotatably connected to the top of the rotating pipe through a sealed bearing. The input end of the high-pressure pump passes through the water tank through a pipe and extends into the tank.

[0011] By adopting this technical solution, water inside the water tank can be pumped into the interior of at least two nozzles using a high-pressure pump.

[0012] Furthermore, a water inlet pipe is connected to the left side of the upper surface of the water tank, and a pipe cap is threaded to the top of the water inlet pipe.

[0013] By adopting this technical solution, a certain amount of water can be injected into the water tank through the water inlet pipe.

[0014] Furthermore, the discharge structure includes a first discharge pipe, with a valve connected to the outside of the first discharge pipe and a second discharge pipe connected to the inside of the valve.

[0015] By adopting this technical solution, the remaining substances inside the tank can be discharged through the discharge structure, and the dirt after cleaning can also be discharged.

[0016] Furthermore, a limiting frame is provided on the right side of the upper surface of the base, and a collection frame is slidably inserted into the limiting frame.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] 1. The separation and purification device for abamectin production, after separation and purification, starts a high-pressure pump. Water from the tank is pumped into the rotating tube through pipes and connecting pipes, and then flows into the left and right spray pipes. It is then sprayed out by no fewer than two nozzles to clean the inside of the tank. During cleaning, the motor is started to drive the left and right nozzles to rotate, which can improve the cleaning effect. At the same time, the left and right scrapers can be driven to rotate through the connecting rods on the left and right sides.

[0039] It should be noted that when cleaning, starting the motor 81 drives the rotating tube 84 and at least two nozzles 874 on the left and right sides to rotate, which can improve the cleaning effect. At the same time, the connecting rods 871 on the left and right sides can drive the scrapers 872 on the left and right sides to rotate.

[0040] The working principle of the above embodiment is as follows: the mixed material can be poured into the tank 2 through the feed cylinder 10, and the sealing cap 11 is twisted and fixed on the outside of the top of the feed cylinder 10. The motor 81 and the heating plate 9 can be started, and the first rotating wheel 82, the second rotating wheel 83, the rotating tube 84, the fixed rod 85 and at least two stirring paddles 86 can be rotated to stir the mixed material inside the tank 2 evenly. The mixed material inside the tank 2 is heated by the heating plate 9. When the mixed material is heated, it is purified by the different boiling points of each substance. The vaporized abamectin flows into the condensation structure 5 through the second discharge pipe 14 for condensation, and then flows into the collection frame 13 through the first discharge pipe 6 for collection. After the process is completed, the high-pressure pump 876 is turned on, and the water inside the water tank 875 is pumped into the rotating pipe 84 through the pipe and connecting pipe 877, and then flows into the left and right spray pipes 873. It is then sprayed out by no less than two nozzles 874 to clean the inside of the tank 2. When cleaning, the motor 81 is started to drive the rotating pipe 84 and the left and right nozzles 874 to rotate, which can improve the cleaning effect. At the same time, the left and right scrapers 872 can be driven to rotate through the connecting rods 871 on the left and right sides. When the left and right scrapers 872 rotate, they can scrape off the remaining material after extraction that is attached to the inner wall of the tank 2, and then discharge it through the discharge structure 3, which improves the cleaning effect and cleaning efficiency.
