Automatic cleaning device for evaporating pot heat exchange tube

Abstract

The invention discloses an automatic cleaning device for an evaporating pot heat exchange tube. The automatic cleaning device comprises a center column, a sliding fame driving mechanism, a machine frame portion, a machine frame wheel portion, a machine frame driving portion, a water pipe clamping wheel mechanism and a water pipe conveying mechanism; one end of the machine frame portion is hinged to the center column, the other end of the machine frame portion is connected with the machine frame wheel portion in a positioned mode, and the length of the machine frame portion can be changed by adding a connection machine frame portion; the machine frame driving mechanism is arranged a front machine frame of the machine frame portion and drives the machine frame portion to rotate around the center column, the sliding frame driving mechanism drives the water pipe clamping mechanism to slide on the side face of the machine frame portion, and the heat exchange tube is positioned in a polar coordinate mode; the water pipe conveying mechanism and the water pipe clamping mechanism are combined to achieving conveying and retracting of a water pipe. The automatic cleaning device for the evaporating pot heat exchange tube can achieve automatic cleaning, the length of the machine frame portion can be enlarged according to the size of an evaporating pot, no cleaning dead space exist in a cleaning range, and the phenomenon that machine frame wheels are blocked because of walking on the surface of an irregular evaporating pot can be avoided.

Description

technical field [0001] The invention relates to the field of cleaning evaporation tanks, and is particularly suitable for cleaning tube-and-tube heaters by high-pressure water jets. technical background [0002] In actual production, due to the influence of the sugar refining process in the sugar factory, after a period of use, the tube heater will deposit calcium sulfite scale with uneven thickness on the inner wall of the tube. Fouling greatly reduces the heat transfer efficiency of the heater, which directly affects the normal progress of the sugar making process. Therefore, it is necessary to descale the heat exchange tubes of the evaporating tank. In the past, chemical descaling methods, manual machinery and high-pressure water cleaning were generally used. The chemical descaling method is time-consuming, high in cost, and corrodes the heat exchange tubes. Manual machinery and high-pressure water cleaning are labor-intensive, inefficient, and unsafe. The tube heaters...
