Description

Technical Field

[0001] The utility model belongs to the technical field of material mixing, in particular to a liquid preparation device for powdered aquatic veterinary medicine. Background Art

[0002] Veterinary drugs refer to substances used to prevent, treat, diagnose animal diseases or purposefully regulate animal physiological functions. Their production process is roughly the same as that of ordinary medicines, and the veterinary drug powder and solution need to be mixed and prepared during the production process. The mixing and preparation process requires the use of a liquid preparation device.

[0003] The traditional liquid dispensing device includes a tank body, in which a stirring mechanism is provided. The stirring mechanism includes a vertically arranged rotating shaft, and a plurality of stirring blades are installed on the outside of the rotating shaft. When performing the liquid dispensing operation, the rotating shaft is driven by a motor to rotate, and the rotating shaft drives the stirring blades to rotate, thereby causing the solution in the tank body to turn over and achieve a mixing effect.

[0004] In the actual working process, it was found that the above-mentioned liquid dispensing device has a relatively simple structure and a limited stirring range. When a large amount of powder needs to be put into the tank body for liquid dispensing operation at one time, some powders will clump to form large powder lumps. In addition, some powders themselves have poor solubility and are also prone to forming large powder lumps. Under the action of gravity, the above-mentioned powder lumps will settle at the bottom of the tank body. Due to the limitations of the stirring range of the stirring mechanism, the bottom of the tank body cannot be stirred, so that the powder material deposited at the bottom of the tank body cannot be fully mixed with the solution, resulting in uneven mixing of the liquid medicine. In addition, when using the above-mentioned liquid dispensing device, it is not convenient to clean the residual medicine on the inner wall of the tank body, resulting in residual medicine, which is easy to corrode the tank body and affect the subsequent liquid dispensing operation. Therefore, it is urgent to design a powder aquatic veterinary medicine dispensing device to solve the above-mentioned problems. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art by providing a device for dispensing aquatic veterinary powdered drugs with a rational structural design. The device can mix and stir the veterinary drug powder multiple times, preventing the powder from settling at the bottom of the tank and affecting the uniformity of the drug liquid mixing, thereby improving the mixing effect. Furthermore, the inner wall of the tank can be cleaned after the dispensing operation is completed, preventing drug liquid residue from affecting the subsequent dispensing process.

[0006] The utility model adopts the following technical solutions to solve the technical problems existing in the known technology: a device for dispensing liquid for powdered aquatic veterinary medicine comprises a mounting bracket, a dispensing tank body is fixedly connected to the mounting bracket, a tank cover is buckled on the top open portion of the dispensing tank body, a discharge port is opened at the bottom of the dispensing tank body and a discharge control valve is installed at the discharge port, and a liquid inlet is installed on the tank cover; a locking member for locking the liquid dispensing tank body and the tank cover is installed between the liquid dispensing tank body and the tank cover; the device also comprises a lifting drive assembly installed on the mounting bracket, which is used to drive the tank cover to lift and move; a stirring motor is fixedly connected to the tank cover, and a spring-loaded spring in the shape of a mountain is installed on the output shaft of the stirring motor.

The liquid after the primary mixing is diffused into the liquid dispensing tank through a plurality of water-permeable holes opened on the primary dissolution cylinder, and the stirring component arranged in the liquid dispensing tank can stir and mix the mixture in the liquid dispensing tank again. Since the primary mixing operation preliminarily mixes the veterinary medicine powder and the solution, it avoids the deposition of large pieces of veterinary medicine powder in the dispensing tank. The bottom of the tank body is cleaned, thereby improving the efficiency of the second mixing; by installing multiple sets of scrapers and bottom scrapers on the stirring assembly, the inner wall of the liquid preparation tank body can be cleaned after the discharge operation is completed, avoiding the residual liquid from corroding the inner wall of the liquid preparation tank body and affecting the subsequent liquid preparation operation; by setting a lifting drive assembly, the tank body cover and the stirring assembly installed thereon can be driven to rise, thereby allowing the multiple sets of scrapers to clean the entire inner wall of the liquid preparation tank body during the rotation and rise process, thereby improving the cleaning range of the scrapers; at the same time, it is convenient to remove the stirring assembly, multiple sets of scrapers and bottom scrapers for cleaning.
