Constant-temperature stirring tank

Abstract

The invention discloses a constant-temperature stirring tank. The constant-temperature stirring tank comprises a tank body. A motor is arranged in the middle of the upper end of the tank body. The output end of the motor is connected with a stirring shaft extending into the tank body. The stirring shaft is provided with two short stirring arms and two long stirring arms. Stirring blades are arranged at the tail ends of the short stirring arms and the tail ends of the long stirring arms. Heating devices are embedded into the short stirring arm and the long stirring arm on one side, and cooling devices are embedded into the short stirring arm and the long stirring arm on the other side. A temperature inductor is embedded into the stirring shaft. A temperature controller is arranged on the right side of the tank body. A feeding pipe is arranged on the left side of the upper end of the tank body, a discharging pipe is arranged at the lower end of the right side of the tank body, dustproof covers are arranged at the tail ends of the discharging pipe and the feeding pipe, and the discharging pipe is provided with a sampling pipe. A partition plate is arranged at the bottom end in the tank body and obliquely arranged. The bottom side of the partition plate is connected with the interior of the tank body through a supporting column. The constant-temperature stirring tank is simple in structure and convenient to use, constant-temperature stirring can be achieved, residues of materials on the bottom are reduced, and stirring is even.

Description

Technical field [0001] The invention relates to the field of stirring devices, in particular to a constant temperature stirring tank. Background technique [0002] The mixing tank is a kind of equipment that mixes the materials evenly through mixing. It mainly uses the mixing shaft to drive the rotation of the mixing gear to mix the materials. Although the existing mixing tank has heating or cooling steps, the temperature control cannot be very precise. For some biological and chemical products that require relatively high temperature, improper temperature control will cause the biological products to deteriorate and also Increase the side reactions of chemical products. The bottoms of the existing mixing tanks are all flat bottoms. When the material is discharged after mixing, the scraper cannot be cleaned to the bottom of the tank. The materials at the bottom of the tank are difficult to clean. Long-term accumulation at the bottom of the tank will affect the purity of the late...

Problems solved by technology

Although the existing mixing tank has heating or cooling steps, the temperature control cannot be very precise. For some biological and chemical products that have relatively high temperature requirements, improper temperature control will cause the biological products to deteriorate. Increase the side reactions of chemical products

Existing mixing tanks have flat bottoms. When discharging after mixing, the scraper cannot clean up to the bottom of the tank. The material at the bottom of the tank is difficult to clean. If it accumulates at the bottom of the tank for a long time, it will affect the purity of the material in the later stage, and if it is cooled and solidified The materials piled up at the bottom of the tank will affect the mixing work in the later stage

And when the stirring device is working, the stirring blade can only stir a layer of raw materials close to the inner wall of the stirring shaft, but a large part of the material between the stirring shaft and the inner wall of the stirring tank cannot be well stirred, so it is prone to uneven stirring Happening
