Description

A mixing reaction tank

technical field

The utility model relates to a reaction tank, in particular to a mixing reaction tank for solid-liquid, liquid-liquid, especially high-viscosity materials. the

Background technique

In the production process of modified starch, it is necessary to put the starch raw material into the mixing reaction tank for a mixing reaction with chemicals to undergo a chemical reaction. During this process, the stirring mechanism needs to be continuously stirred. When the existing mixing reaction tank encounters materials with high viscosity, they often cannot fully mix them, and the materials rotate together with the stirring shaft, so that the materials are mixed unevenly. In addition, although some of the existing mixing reaction tanks have temperature measuring devices, they are generally installed at the discharge port, which cannot accurately grasp the temperature changes of the materials during the heating process of the mixing reaction tank, which is inconvenient for operators to control. the

Utility model content

The technical problem to be solved by the utility model is to provide a mixing reaction tank with good stirring effect and real-time observation of the temperature of the material in the tank. the

In order to solve the above technical problems, the utility model takes the following technical solutions:

A mixing reaction tank, including a tank body and a stirring shaft, the stirring shaft includes an outer shaft and an inner shaft, the inner shaft is sleeved in the outer shaft, the outer shaft is connected to the outer shaft motor installed on the upper end of the tank body, the inner shaft is connected to the The inner shaft motor on the upper end surface of the tank body is connected, and the outer shaft is connected with a frame that is slidingly fitted with the inner wall of the tank body, and the outer paddle blades are installed on the frame. Inner paddle blades spaced apart from the outer paddle blades and arranged in a staggered manner are installed on the inner shaft. the

The outer surface of the inner shaft is also equipped with a temperature sensing probe, and the temperature sensing probe is connected with a temperature display mounted on the upper end surface of the tank through a wire. the

The utility model adopts two motors to output two kinds of stirring mechanisms for relative motion, which has good stirring effect, avoids the phenomenon that the materials rotate with the paddle blades, and ensures that the materials are fully and uniformly mixed. In addition, a temperature sensing probe is installed on the inner shaft to observe the temperature of the material in the tank in real time, which is convenient for the operator to operate. the

Accompanying drawing 1 is the utility model sectional structure schematic diagram. the

Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings. the

As shown in accompanying drawing 1, a kind of mixing reaction tank comprises tank body 1 and stirring shaft, and stirring shaft comprises outer shaft 21 and inner shaft 31, and inner shaft 31 is sleeved in outer shaft 21, and outer shaft 21 is contained in tank body 1 is connected to the outer shaft motor 22 on the upper end surface, and the inner shaft 31 is connected to the inner shaft motor 32 installed on the upper end surface of the tank body 1. The outer shaft 21 is connected to a frame 4 that is slidingly fitted with the inner wall of the tank body 1. The frame 4 An outer paddle blade 41 is installed on the top, and an inner paddle blade 5 spaced apart from the outer paddle blade 41 and arranged in a staggered manner is installed on the inner shaft 31 . A temperature sensing probe 6 is also installed on the outer surface of the inner shaft 31, and the temperature sensing probe 6 is connected with a temperature display 7 mounted on the upper end surface of the tank body 1 through a wire. the

The utility model adopts two motors to respectively drive the outer shaft paddle blade and the inner shaft paddle blade to make relative motion, so that the material is more fully and evenly stirred; a temperature sensing probe is also arranged on the inner shaft in the tank body to sense the temperature of the material in the tank body in real time. The temperature is convenient for the staff to know the temperature of the material in real time. the

The above-mentioned embodiment is one of the preferred implementation modes of the utility model. It should be noted that any obvious replacement is within the protection scope of the utility model without departing from the inventive concept of the utility model. the
