Description

Technical Field

[0001] The invention belongs to the technical field of ivermectin preparation, and particularly relates to a high-efficiency anti-parasitic special ivermectin preparation device and a preparation process. Background Art

[0002] Ivermectin, a highly effective antiparasitic drug, is a new type of broad-spectrum, highly effective, low-toxic antibiotic antiparasitic drug. It has a good killing effect on parasites inside and outside the body, especially nematodes and arthropods, and is often used for the treatment of animals. When preparing ivermectin, toluene and avermectin are added to the reactor in a reaction kettle, and a catalyst is added under the protection of protective gas. After the protective gas is replaced with hydrogen, the heating temperature is adjusted to 65-75°C and the pressure is 0.5-0.7MPa. Avermectin reacts with hydrogen to obtain ivermectin crude product. The ivermectin crude product is dissolved in a solvent, heated and stirred until completely dissolved and kept warm to obtain a crude solution. Purified water and formamide are added to the crude solution and the flow rate is controlled. The solution is cooled to obtain a diluent. Crystal seeds are added to the diluent and crystals are grown. The diluent is cooled to a certain temperature by a temperature control method. Finally, high-purity ivermectin powder is obtained by filtration, washing and drying.

2. A process for preparing a highly effective antiparasitic ivermectin, using the highly effective antiparasitic ivermectin preparation device according to claim 1, characterized in that: The following steps are involved: S1. Feeding and stirring: First, the feed pump (1021) is connected to the output end of the ivermectin crude solution conveying device, and then the preparation mechanism (1) is powered on and started. When the ivermectin crude solution enters the storage tank (1011), the servo motor (1031) converts electrical energy into rotational mechanical energy, and then transmits the rotational mechanical energy to the rotating rod (1032). The rotating rod (1032) rotates with the servo motor (1031) and drives the stirring tube (1033) to rotate. The ivermectin crude solution will move with the stirring of the stirring tube (1033) and form a vortex. At the same time, the ivermectin crude solution will pass through the stirring tube (1033) when moving. After the ivermectin crude solution is stirred, the crystallization mechanism (2) is used to crystallize the ivermectin crude solution. After the ivermectin crude solution is crystallized, the exhaust fan (1013) exhausts the excess gas in the storage tank (1011) after the reaction until the preparation of ivermectin is completed. S2. Heating and crystallizing: First, a seed crystal is placed in the storage box (2032), and then the storage box (2032) is placed in the limit slot (2022), and the limit frame (2021) is placed in the limit box (2011) along the limit slide (2012) until the closing plate (223) contacts and closes the access slot (2013), and then the ivermectin crude solution that has completed the stirring process is transported to the storage box (2032), and then the crystallization mechanism (2) is powered on and started. After the power is turned on, the heater (2043) will The electrical energy is converted into thermal energy, which is then transferred to the heat conducting plate (2041). The heat conducting plate (2041) transfers the heat to the heat conducting ring (2042). The heat conducting plate (2041) and the heat conducting ring (2042) transfer the heat to the ivermectin crude solution. The ivermectin crude solution and the seed crystals gradually undergo a crystallization reaction due to the heat. After the ivermectin crude solution and the seed crystals have completely completed the crystallization reaction, the limiting frame (221) can be removed from the access slot (2013) to take out the prepared ivermectin.
