Description

Technical Field

[0001] The utility model relates to the technical field of veterinary drug intermediates, in particular to drying equipment for preparing veterinary drug intermediates. Background Art

[0002] Veterinary intermediates refer to chemical raw materials or products used to manufacture veterinary drugs. There are many types of veterinary intermediates, including antibiotics, antiparasitics, antimicrobials, etc. These intermediates usually go through a series of complex chemical synthesis and processing processes, including reaction, filtration, purification, concentration, drying, etc. Drying is an important part of the preparation process and directly affects the quality and stability of the intermediates.

[0003] The existing drying equipment for the preparation of veterinary drug intermediates on the market has the following defects: common drying equipment usually does not have an effective preheating function. Even if multi-stage drying is adopted, static drying is adopted, resulting in the granular veterinary drug intermediates being unable to reach a suitable temperature before entering the hot oven. This not only prolongs the drying time, but also affects the drying effect, resulting in uneven drying of the intermediates, which often leads to wall formation and caking, affecting product quality.

[0004] Therefore, a drying device for preparing veterinary drug intermediates is needed to solve the above technical defects. Utility Model Content

[0005] The purpose of the utility model is to provide a drying device for preparing veterinary drug intermediates, so as to solve the problem of lack of effective preheating function in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drying equipment for preparing veterinary drug intermediates, comprising a cylinder and a fixed seat, a hot oven is installed on the right side inside the cylinder, and a preheating feeding mechanism is arranged on the left side of the top end of the cylinder; the preheating feeding mechanism comprises a group of fixed seats movably assembled on the upper left side of the inner wall of the cylinder, and limited seats are arranged on the left and right sides of the fixed seat, and spring rods are respectively installed between the limited seat and the fixed seat, and two groups of spring columns are vertically arranged inside the fixed seat, and a vibration block is sleeved in the middle position of the spring column, and a group of eccentric disks are movably connected to the left side of the front end and the right side of the rear end of the vibration block, and a feeding channel is fixedly connected to the top of the fixed seat, an electric heating radiation plate is installed in the feeding channel, and a feeding port is arranged on the right side of the electric heating radiation plate, and a plurality of groups of anti-collision springs are evenly installed between the outer wall of the feeding channel and the cylinder.

Driven by the reduction motor, the spiral conveyor shaft pushes the particles out at a uniform speed. The material is discharged automatically and the discharge speed can be adjusted by controlling the speed of the reduction motor, thus reducing the time consumption of manual material collection.
