AI Technical Summary

Technical Problem

During the preheating process of existing low-temperature vacuum evaporators, the water source is prone to cause uneven heating, resulting in uneven preheating temperature of the liquid inside the device body, affecting the overall preheating effect.

Method used

A low-temperature vacuum evaporator including a heat mixing device, a converging device and a scale-slimming device is designed. The heat mixing device ensures uniform heating of the water source through the coordination of the electric rotary rod, agitating plate and heating assembly; the convergence device promotes heat exchange of the water source in the heating barrel through the coordination of the spoiler frame and the flip plate; the scale-blocking device prevents scale erosion and bubble formation through the coordination of the sliding arc plate and the elastic arc plate.

Benefits of technology

The uniform heating of the water source is achieved, the preheating time of the device body is shortened, the uniformity of the liquid preheating temperature is ensured, the overall preheating efficiency is improved, and scale erosion and bubble formation are prevented.

Abstract

The invention discloses a low-temperature vacuum evaporator capable of rapidly preheating, and relates to the technical field of environmental protection equipment. The device comprises a heat preservation tank, a device body is arranged in the heat preservation tank, a circulating pipe is arranged between the outer wall of the device body and the inner wall of the heat preservation tank, a supporting frame is arranged on the outer wall of the heat preservation tank, and a heating barrel is arranged on the left side of the supporting frame. By means of the stirring plate, the situation that when the heating assembly heats a water source in the heating barrel, the water source is in a static state all the time, and consequently the heat exchange efficiency is affected is avoided, temperature fluctuation during water source temperature rising is reduced, and it is guaranteed that the water source is integrally and evenly heated; the temperature of a water source pumped by the water pumping gun is still balanced, and the situation that the preheating temperatures of liquid at different positions in the device body are different due to uneven water temperature is prevented.
