The technical scheme includes that the hot blast stove comprises a blower, a casing, a support and a plurality of heaters, wherein an outlet end of the blower is communicated with one end of the casing arranged on the support, the plurality of heaters are installed in the casing along the length direction at an equal interval, each of the heaters comprises a plurality of electrical heated tubes arranged in a matrix form, a far infrared coating is arranged on each of the electrical heated tubes, crystallized magnesium oxide is filled into each of the electrical heated tubes, and the casing is sequentially composed of an inner layer plate, a thermal protective layer and an outer layer plate from inside to outside. The hot blast stove is applied to mine entrances for freeze proofing.
Description
Technical field
The utility model relates to a kind of hot-blast stove.
Background technology
The 102 regulation of China's " safety regulations in coal mine ": the air themperature below the air intake well head must be more than 2 degrees centigrade.Well head is antifreeze to be the important assurance of colliery safety in production in winter.Get into winter, mine must be taked effective antifreezing measures, guarantees wellhead temperature more than 2 degrees centigrade, prevents that well head from freezing.
Home and abroad colliery tradition well head winterization system mainly provides the mode of steam source to solve by coal-burning boiler at present.In decades, China's well head is antifreeze also to be to continue to use this mode always, use comparatively extensive, this mode exist take up an area of many, investment is big, the consumption coal is high, energy consumption greatly, the shortcoming of contaminated environment, economic benefit and environmental benefit are relatively poor.
The utility model content
The purpose of the utility model provides a kind of mine well head electrical heating type hot-blast stove that is used for, with solve the present colliery antifreeze use coal-burning boiler of tradition well head exist take up an area of many, investment is big, the consumption coal is high, energy consumption greatly, problem of environment pollution caused.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: said hot-blast stove comprises pressure fan, housing and support; Said hot-blast stove also comprises a plurality of heaters, and the port of export of pressure fan is communicated with an end of housing, and housing is contained on the support; Equidistantly be provided with a plurality of heaters along its length direction in the housing; Each heater comprises a plurality of electrothermal tubes, and a plurality of electrothermal tubes are cells arranged in matrix, and each electrothermal tube is provided with the far infrared coating; Fill crystal magnesium oxide in each electrothermal tube, housing is made up of inner plating, thermal insulation layer and lamina rara externa from the inside to the outside successively.
The utlity model has following beneficial effect: the utlity model has simple in structure, floor space is little, investment is little, characteristics such as pollution-free; It is heater antifreeze for the mine well head and that heating provides; With electric energy is main heat; (replacing traditional fuel hot-blast stoves such as fire coal, combustion gas) takes place in no any fuel and pernicious gas, is the antifreeze preferred equipment of mine well head.
