Low-temperature evaporator for automatically treating sewage scales

Abstract

The invention relates to an evaporator, which has the effect of being easy and convenient to maintain. The invention discloses a low-temperature evaporator capable of automatically treating sewage scales. The low-temperature evaporator comprises a shell, wherein a plurality of water pipes parallel to the length direction of the shell are uniformly arrayed in the shell, the upper end and the lowerend in the shell are each provided with a partition plate for sealing the inner cavity of the shell, the water pipes penetrate through the two partition plates in an attached mode and are welded and fixed to the partition plates, the shell is provided with a refrigerant inlet and a refrigerant outlet which are located between the two partition plates, the shell is provided with a water inlet and awater outlet which are located outside the two partition plates respectively, a lifting plate which is located outside the partition plate and parallel to the partition plate is arranged in the shell, a plurality of scale scraping springs which are attached to and inserted into the water pipes respectively are arranged on the lifting plate, and an air cylinder which drives the lifting plate to ascend and descend in the length direction of the shell is arranged outside the shell. By means of cooperation of the scale scraping spring and the water pipes, automatic scale scraping is achieved, andregular cleaning is not needed.

Description

technical field [0001] The invention relates to an evaporator, more specifically, it relates to a low-temperature evaporator for automatically treating sewage scale. Background technique [0002] Generally speaking, an evaporator is a device that converts a liquid substance into a gaseous state. The evaporator is a very important part of the four major components of refrigeration. The low-temperature condensed liquid passes through the evaporator, exchanges heat with the outside air, vaporizes and absorbs heat, and achieves the effect of refrigeration. The evaporator is mainly composed of two parts: a heating chamber and an evaporation chamber. The heating chamber provides the heat needed for evaporation to the liquid, which promotes the boiling and vaporization of the liquid; the evaporation chamber completely separates the gas-liquid two phases. [0003] The patent with publication number CN110967317A and publication date 2020-04-07 discloses an evaporator scale detectio...
