Stirring device applicable to medicines and chemical raw materials

Abstract

The invention discloses a stirring device applicable to medicines and chemical raw materials. The stirring device comprises a stirrer casing, wherein a stirrer casing cover covers the top of the stirrer casing, a motor is fixedly mounted at the top of the stirrer casing cover, a raw material inlet is arranged on one side of the motor, the front end of the motor is sleeved with a stirring shaft, a stirring vane is fixed at the bottom of the stirring shaft in a key joint manner, a horizontal blade is mounted at the bottom of an inner cavity of the stirrer casing, vertical blades are mounted on the periphery of the horizontal blade, a discharging pipeline is arranged at the lower part of the outer side of the stirrer casing, and a precipitation tank is arranged at the bottom of the stirrer casing. According to the stirring device applicable to the medicines and the chemical raw materials, the motor and the raw material inlet are mounted at the top of the stirrer casing cover, so that opening for replacement can be performed conveniently after internal components in a stirrer are damaged; the stirring vane and the stirring shaft are fixed in the key joint manner, and accordingly, the stirring vane is convenient to dismount and replace after damaged.

Description

technical field [0001] The invention relates to the technical field of stirring devices, in particular to a stirring device suitable for medical and chemical raw materials. Background technique [0002] Mixer is a kind of mechanical equipment that can evenly mix materials. It has been widely used in many industrial sectors, especially in the production of chemical raw materials and pharmaceuticals. Mixers are particularly important. Common mixers are divided into single-axis and double-axis according to the number of shafts. There are two types. The single-shaft mixer has only one main shaft, and the double-shaft mixer has two parallel main shafts. The mixing knife on the mixing shaft is generally a continuous spiral structure or a single blade, but the structure of the spiral mixing knife is complicated, and the mixing time of the blade mixing knife Long, the uniformity of the mixture is poor, it is difficult to meet the requirements, and in the process of mixing, due to t...

[0002] Mixer is a kind of mechanical equipment that can evenly mix materials. It has been widely used in many industrial sectors, especially in the production of chemical raw materials and pharmaceuticals. Mixers are particularly important. Common mixers are divided into single-axis and double-axis according to the number of shafts. There are two types. The single-shaft mixer has only one main shaft, and the double-shaft mixer has two parallel main shafts. The mixing knife on the mixing shaft is generally a continuous spiral structure or a single blade, but the structure of the spiral mixing knife is complicated, and the mixing time of the blade mixing knife Long, the uniformity of the mixture is poor, it is difficult to meet the requirements, and in the process of mixing, due to the crushing of the material or the incomplete mixing in the early stage, the mixing effect will also be affected. For example, the mixer with the patent number "201420590813.6" includes a fixed base , the stirring cylinder, the stirring device and the motor above the stirring cylinder, the stirring device includes a first stirring shaft, a second stirring shaft, a first stirring block and a second stirring block which are correspondingly arranged at the bottom of the first stirring shaft and the second stirring shaft block, the surface of the first stirring block and the second stirring block close to the inner wall of the mixing cylinder is a circular arc surface and matches the inner wall of the mixing cylinder, and grooves are respectively opened under the two stirring blocks. The whole device only adds more It is just a stirring shaft, which is still not significantly changed compared with the usual mixer, and the traditional mixer will convey the stirred raw materials after the mixing is completed. In many cases, a lot of impurities will be produced during the mixing process, which needs The impurities are further processed and then exported to ensure the purity of the stirred material and meet the needs of the next production step. Therefore, a mixer is needed that can achieve a better mixing effect when mixing different raw materials. It can also further crush the raw materials to make the mixing more thorough, and at the same time, it is necessary to deal with the impurities after mixing
