Abstract

The invention discloses a mining heating system based on a graphene carbon fiber electrothermal film, which relates to the field of mining temperature control. The system comprises an electrical control system, a monitoring system and an electrothermal film fixing and protecting device, wherein the electrical control system is a double-temperature control system and comprises a power supply circuit, a load circuit, a double-control circuit, a PLC control circuit and a K-type temperature controller circuit. The monitoring system comprises configuration monitoring and video monitoring, temperature values and video information are collected through a temperature sensor and a video monitoring camera respectively, and alarm conditions are set for control; the electrothermal film fixing and protecting device comprises an electrothermal film fixing and protecting device body fixed to the gate and an electrothermal film fixing and protecting device body fixed to the residual load, each comprises an electrothermal film and an aluminum silicate heat preservation cotton layer, and heat is only conducted to a place needing to be heated. The problem of environmental pollution is effectively solved, a large amount of manpower, material resources and financial resources are saved, and the safety of heating or warming is guaranteed.

Description

technical field [0001] The invention relates to the field of mine temperature control, in particular to a mine heating system based on graphene carbon fiber electrothermal film. Background technique [0002] On the ground of some coal mines, coal storage bunkers with large reserves are generally built for loading of trains, and the lower part of the coal storage bunkers is provided with coal leakage nozzles and gates. In winter, effective anti-freezing measures must be taken to ensure that coal leaks and gates do not freeze, and to ensure that trains are delivered on time. In the past, coal-fired boilers were usually used in mines to provide hot air to the bottom of the coal storage bunker for anti-freezing purposes. For example, a 4,000-ton coal storage bunker needs to use 2 tons of coal per year. However, this method has high energy consumption and high pollution, and it belongs to the equipment that is explicitly eliminated by the environmental protection policy, so it n...
