With the development and utilization of coal and other mineral resources, mine safety issues have become increasingly prominent. Among them, as an important equipment in mining, the safety and stability of the medicine cabinet are very important for the safe production of mines. Therefore, this article will focus on the principle and design of mine insulated anti-medicine cabinets.
First, the principle of mine insulated anti-medicine cabinet.
The mine insulated anti-medicine cabinet is mainly composed of a cabinet body, an insulating layer, a heating system, a temperature control system and an alarm system. Its working principle is mainly based on the principle of heat conduction and heat convection.
First, heat conduction refers to the transfer of heat inside an object through the movement of molecules, atoms, or electrons. In the mine insulated anti-chemical cabinet, heat conduction mainly occurs between the insulation layer and the heating system. When an electric current is passed through the heating system, heat is generated, which is transferred to the insulation by means of heat conduction.
Secondly, thermal convection refers to the transfer of heat in a fluid medium through the flow of fluids. In the mine insulated anti-chemical cabinet, the thermal convection mainly occurs between the heating system and the cabinet. When the insulation receives heat, it will transfer heat to the cabinet in the form of thermal convection, which will increase the temperature in the medicine cabinet.
At the same time, the temperature control system and alarm system are also an important part of the mine insulated anti-medicine cabinet. The temperature control system detects the temperature in the medicine cabinet through the temperature sensing probe, and feeds back the temperature information to the control center, which adjusts the power of the heating system according to the feedback information to keep the temperature in the medicine cabinet within the set range. The alarm system is to send out an alarm and cut off the power supply when the temperature in the medicine cabinet exceeds the set range to prevent the occurrence of accidents.
Second, the design of mine insulated anti-medicine cabinet.
The following aspects should be considered in the design of mine insulated anti-medicine cabinets:
Material selection: The cabinet body should be made of high-temperature and corrosion-resistant materials to ensure that the medicine cabinet works normally in a high-temperature and high-humidity environment. The insulation layer should be made of materials with good insulation performance and high temperature resistance, such as ceramic fiber paper.
Structural design: The structural design of the medicine cabinet should be reasonable, so that heat conduction and heat convection can be carried out effectively. At the same time, the structural design should also take into account factors such as ease of cleaning and maintenance, as well as the prevention of dust accumulation.
Heating system design: The design of the heating system should take into account factors such as uniform heating and high efficiency. Heating elements such as electric ** and electric heating plates can be used, and appropriate power regulators should be set up to achieve accurate temperature control.
Temperature control system design: The temperature control system should have the characteristics of high precision and high stability, and can use advanced control algorithms and sensor technology to achieve accurate temperature control. At the same time, the alarm system should be linked with the temperature control system, and when the temperature exceeds the set range, an alarm will be issued in time and the power supply will be cut off.
Safety design: The medicine cabinet should be equipped with a safety door lock and an emergency stop button to prevent non-professional misoperation. At the same time, the medicine cabinet should also be equipped with explosion-proof devices to prevent accidents.
III. Conclusion. As an important equipment in mining, the safety and stability of the mine insulated anti-medicine cabinet are very important for the safety production of the mine. Therefore, the understanding and research of its principle and design should be strengthened to continuously improve its performance and reliability. At the same time, the management of its use and maintenance should also be strengthened to ensure its normal operation and safe use.
