The utility model includes a filtering device, a fixing device and a protective device, and the protective device and the fixing device are both arranged inside the filtering device. The utility model implements multi-layer filtration of veterinary drugs through the filtering device to improve the purity of veterinary drugs. At the same time, the fixing device is used to install and fix the filter screen inside the filtering device, which is convenient for the removal and cleaning of the filter screen after the filtration is completed, which greatly facilitates the use. The protective device effectively reduces the impact force of the liquid medicine during the dosing process, prevents the liquid medicine from directly impacting the filter screen, causing damage to the filter screen, improves the protectiveness of the filter screen, and at the same time improves the sealing of the device, effectively preventing the liquid medicine from splashing during the dosing process and splashing out of the device, causing waste.

[0004] The above-mentioned veterinary drug filter tank is equipped with a double-layer filter screen in the filter tank to filter and intercept particulate matter in the veterinary drug solution. However, the problem with this design is that after the filter screen has been used for a period of time, a certain amount of filter interception material will accumulate on the surface of the filter screen, thereby slowing down the flow rate of the filter medium. It is also very troublesome to disassemble and clean the filter screen in the filter tank. Utility Model Content
