PVC stripping roller closed-loop circulating filtering cooling device

Abstract

The invention discloses a PVC stripping roller closed-loop circulating filtering cooling device. The device comprises a cabinet body, an upper layer plate and a lower layer plate are arranged in the cabinet body to divide the cabinet body into an upper cavity, a middle cavity and a lower cavity, and each cavity is provided with a front cabinet door and a rear cabinet door; a circulating pump, an input port and an output port are arranged in the lower chamber; two radiators are arranged in the middle cavity, the radiators are provided with first temperature sensors, and openings are formed in the positions, corresponding to the radiators, of the cabinet plates; the upper chamber is provided with a filtering water tank, a control electric box and a draught fan, a display and control panel isarranged outside the corresponding cabinet door, and a second temperature sensor and a liquid level sensor are arranged in the filtering water tank; and the input port is connected with the two radiators in series through pipelines, water enters the filtering water tank, passes through the circulating pump and is finally discharged from the output port, and all the temperature sensors, the liquidlevel sensor, the draught fan and the circulating pump are electrically connected with the control electric box. The device and a stripping roller realize closed-loop water circulating cooling, the water resource loss is small, the stripping roller is not polluted, the maintenance period is long, and the process temperature parameter of the stripping roller is ensured.

Description

technical field [0001] The invention relates to a PVC stripping roller closed-circuit circulation filtering and cooling device. Background technique [0002] There are many factors that determine the quality of PVC sheets in the PVC production line. One of the most critical factors is the temperature of the PVC stripping roller. If the temperature is too high, the stripping roller will not peel off cleanly. There are flow lines, and the shape of the sheet is poor, and the off-cut material is easy to break during online production, which affects production capacity and increases the labor intensity of employees. If the temperature is too high or too low, the quality of the PVC sheet will be unqualified. The typical unqualified phenomena are poor transparency, flow lines and uneven thickness. Not only is there a lot of waste, but also the production capacity is greatly reduced. [0003] Now most of the peeling rollers of PVC, PP, PE and other sheet production lines are equipp...

Problems solved by technology

It is not difficult to understand that every cleaning and maintenance must be carried out when the production line is shut down. Every shutdown will cause manpower and material resources and affect production. This is a great loss for the enterprise.
