An Automatically Controlled Mixed Phase Change Material Melting and Filling Device

Abstract

The invention discloses an automatically controlled hybrid phase change material melting and filling device which contains a temperature controllable heating constant-temperature cycle working medium case and an automatic filling, immersion and heating furnace. The heating constant-temperature cycle working medium case is composed of an electric heater and a case body. The bottom of the heating constant-temperature cycle working medium case is provided with two pairs of universal wheels, a heating working medium compensation port, an overflow port and a dirt discharge port. A heating working medium outlet and a heating working medium inlet are formed in the side face of the case body. A plurality of holes are dispersed in a cover plate on the top of the case body, and unit tubes to be filled are inserted in the holes. The outer layer of the automatic filling, immersion and heating furnace is a heating cycle working medium channel which is provided with a heating working medium inlet, a heating working medium outlet and a liquid level meter. The inner layer of the automatic filling, immersion and heating furnace is filled with a phase change material to be molten. The bottom of the automatic filling, immersion and heating furnace is connected with an unloading pipe and an electric adjusting valve. A lifting stirrer is arranged in the hollow portion of the automatic filling, immersion and heating furnace. Since a loading device adopts a belt with the discharging amount controlled by weighing to conduct conveying, multi-batch quantitative automatic filling is achieved. The case body and an outer cavity of a melting furnace form a cycle heating working medium loop with the whole process being constant in temperature. The automatically controlled hybrid phase change material melting and filling device is reasonable in structure, reliable in performance, easy and convenient to operate and high in filling speed.

Description

technical field [0001] The invention relates to a melting and filling device for mixed phase change materials, in particular to a stirring mixing and batch integrated filling of various materials soaked in a bath and heated until melting, which is suitable for the homogeneity of phase change materials and their auxiliary materials and composite materials in various temperature ranges. Substance preparation realizes liquid filling of phase change material storage and packaging units. Background technique [0002] The energy storage theory and application research of phase change materials has achieved rapid development in recent years. Among them, the hydrated salt refers to the compound substance containing crystal water. The water in it is combined with the internal structure of the substance in a certain stable state, so it is a hydrate with a fixed ratio of crystal water in a relatively stable state and a high thermal effect. For inorganic hydrated salt phase change mate...
