Embodiment Construction

[0008] The thermal oil system of the present invention is described in conjunction with the accompanying drawings. Such as figure 1 As shown, the system is mainly composed of thermal oil furnace 1, pump 2, platinum thermal resistance 3, thermal oil roller 4, electric proportional three-way valve 5, large circulation pump 6, and pipeline 7; under the set conditions, a large Circulation: The high-temperature heat-carrying oil from thermal oil furnace 1 passes through line a——b——c——electric proportional three-way valve 5——h—large circulation pump 6——i and returns to thermal oil furnace 1, Such a cycle; also can form a small cycle: high temperature heat transfer oil through the line d - e - pump 2 - platinum thermal resistance 3 - hot oil roller 4 - f - g and then return to d, and so on.

[0009] 1. Set the temperature of the heat carrier after deployment according to the needs. When the set requirements are met, the electric proportional three-way valve (5) is in the closed stat...

Abstract

The invention discloses a control system which belongs to a deep fat drying plant in textile industry and mainly consists of a thermal oil heater, a pump, a platinum resistance thermometer, thermal oil rollers, an electric proportion triple valve, a large circulating pump and a pipeline; under set conditions, the large circulation can be formed: the high temperature heat-carrying oil from the thermal oil heater sequentially passes through lines a-b-c-the electric proportion triple valve (5)-h-the large circulating pump i-the thermal oil heater, the circulation proceeds; a small circulation can be formed as well: the high temperature heat-carrying oil sequentially passes through lines d-e-the pump-the platinum resistance thermometer-the thermal oil rollers (4)-f-g-d, so does the circulation proceed. The control system causes excellent temperature uniformity of the thermal oil roller.

Description

technical field [0001] The invention belongs to the control system of hot oil roller drying equipment in the textile industry. Background technique [0002] With the development of society, the requirements for product quality are getting higher and higher, and there are also higher requirements for the temperature uniformity of the hot roller surface. Because the uniformity of the roller surface temperature directly affects the quality of the product and its quality stability. In the past, in order to improve the uniformity of the roller surface temperature, a method was often found on the structure of the hot oil roller, which made the structure of the hot oil roller complicated, difficult to manufacture, and high in cost. Even so, when the length of the roller surface continues to increase, the temperature difference between the left and right sides of the roller surface can only be controlled at about ±7°C, which cannot meet the requirements of some fabrics with higher ...
