Description

Concentration evaporation equipment

Technical Field

The utility model relates to the field of stirring equipment, in particular to concentration and evaporation equipment.

Background

In the chemical production process, the concentration of the solution is needed to be increased in many places by concentration and evaporation, so that other working procedures are more economical and reasonable. In the whole concentration process, the solution is heated to boil, and moisture or other volatile solution parts in the solution reach a gasification state and are continuously removed, so that solid substances or solutes in the solution are concentrated.

Most of the current market adopts a thin film evaporator, the thin film evaporator heats and gasifies the solution in the container through the jacket, the liquid level in the container is continuously reduced along with continuous evaporation of water or volatile solution, the height position of the jacket heating part is inconsistent with that of the solution, most of the jacket heating area cannot be in contact with the solution for heat transfer, the evaporation area is continuously reduced, the energy waste is serious, and the exposed heating inner wall enables the solution on the wall to be coked and shed, so that the quality of the concentrate is influenced.

Disclosure of utility model

In order to overcome the defects of the background technology, the utility model provides the concentrating and evaporating equipment which reduces energy consumption and time and improves concentrating efficiency and quality.

The utility model adopts the technical scheme that: the utility model provides a concentrated evaporation equipment, its includes the container that has the heating jacket, inserts (mixing) shaft and the pivoted driving piece of drive (mixing) shaft in the container, the circumference of (mixing) shaft is equipped with the body that a plurality of both ends link up, the distance between body upper end and the (mixing) shaft is greater than the distance between body lower extreme and the (mixing) shaft.

The pipe body adopts a round pipe or an elliptic pipe.

The pipe body is 30-60 degrees with the axis of the stirring shaft, and the number of the pipe bodies is 2-4.

The distance between the upper end of the pipe body and the inner wall of the container is 10-50mm.

The length-diameter ratio of the container is 1-1.5:1, and the charging coefficient is less than 80%.

A plurality of connecting rods which are fixedly connected with the stirring shaft and the pipe body are arranged between the stirring shaft and the pipe body.

The beneficial effects of the utility model are as follows: according to the technical scheme, the solution to be evaporated is continuously conveyed to the jacket heating surface through the pipe body in a lifting manner by stirring and rotating centrifugal force, so that the initial and final solution evaporation areas are kept unchanged, the concentration efficiency and quality are greatly improved, and the energy consumption and the operation time are reduced.
