Casting waste heat recycling device based on radiant heat exchange

Abstract

The invention relates to a casting waste heat recycling device based on radiant heat exchange. The casting waste heat recycling device comprises a steel caterpillar band, an aluminum waste heat recycling device, a water storage box, a circulating water pump, a circulating water pipe, a temperature sensor, a temperature controller, solenoid valves, an absorption refrigeration device and a heating pipe net device; the aluminum waste heat recycling device with the model cross section is arranged on the steel caterpillar band; a water outlet of the water storage box is connected with a water inlet of the waste heat recycling device through the circulating water pipe, and the circulating water pump is arranged on the circulating water pipe; a water outlet of the waste heat recycling device is provided with the temperature sensor and the temperature controller, and the temperature controller is used for controlling opening and closing of the two solenoid valves; and hot water pipes behind the solenoid valves are connected with the water storage box, the absorption refrigeration device and the heating pipe net device. According to the casting waste heat recycling device, while high temperature casting waste heat is recycled, the internal structure character of a casting is not influenced. The overall device is fewer in motion part, safe, reliable, long in service life, easy to maintain and environment-friendly, and continuous recovering of the high temperature casting waste heat under intermittent production of small and medium size casting enterprises can be achieved.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery and utilization, in particular to a high-temperature casting waste heat recovery and utilization device based on radiation heat exchange, specifically a device for effectively recovering and utilizing the waste heat of exposed high-temperature castings after sand falling. Background technique [0002] With the rapid development of society, energy conservation and emission reduction have been paid more and more attention, and the recovery and utilization of industrial waste heat has always been the focus of energy conservation and emission reduction. At present, the high, medium and low-grade waste heat recovery and utilization technologies involved in continuous production enterprises are basically mature, but in intermittent production industries such as foundry industry, the development and promotion of waste heat recovery and utilization technologies still need to be strengthened.
