Abstract
The utility model discloses a mining heater unit, and relates a steam heater unit which belongs to ventilation heating equipment, and is particularly suitable for ventilating and heating coal mine and various mine entrances. The mining heater unit comprises a fan positioned in a box body, wherein cold air needs to pass through an incoming air temperature sensor before passing through the fan; cold air blown from the fan passes through a steel aluminium finned tube exchanger, and hot air in the steel aluminium finned tube exchanger passes through an outgoing air temperature sensor so as to enter a mine; and the incoming air temperature sensor and the outgoing air temperature sensor are connected with an intelligent controller through cables. A steam inlet pipeline of the steel aluminium finned tube exchanger is provided with an electric control valve. The heater unit provided by the utility model has the advantages of high heat transfer effect and high outgoing air temperature precision, and can more save energy sources.
Description
Technical field
The utility model relates to a kind of steam warm-air machine group, belongs to ventilation and heating equipment, is specially adapted to colliery and various pithead ventilation heating.
Background technology
Antifreeze and the light pipe radiator of the existing antifreeze employing hot-blast stove of pithead heats, and this mode of heating not only thermal efficiency is low, causes the waste of the energy, and has naked light that the safety in production in colliery is also had certain unsafe factor at mine mouth.
The defects that heating exists for the hot-blast stove pithead, the purpose of this utility model provides a kind of brand-new steam warm-air machine group.This warm braw unit can not only improve heat exchange efficiency, avoid mine mouth naked light to occur, and the assembly of this warm-air drier is put the Intelligent central control system and can according to the variation of environment temperature regulating electric control valve voluntarily, be guaranteed that wind pushing temperature is constant, to guarantee comfortableness, reliability and the security of working environment.
Summary of the invention
It is a kind of according to temperature signal regulating electric control valve that the purpose of this utility model is to provide, the device of control steam flow, and the hot blast temperature of realizing entering mine mouth is constant.
The utility model is realized in the following way:
Mining warm braw unit comprises: the EAT sensor, and blower fan, the steel aluminum finned tube heat exchanger in the blower fan back will pass through the leaving air temp sensor from steel aluminum finned tube heat exchanger hot blast out; Intelligent controller and EAT sensor, leaving air temp sensor and electric control valve connect.
In above-mentioned mining warm braw unit, when cold air enters blower fan through the EAT sensor first, blower fan is sent cold wind the heating of to steel aluminum finned tube heat exchanger, enters mine after the hot blast of heating is by the leaving air temp sensor.
When the air EAT was low, the EAT sensor transferred temperature to electrical signal transfer to intelligent controller, and intelligent controller will be driven large electric control valve, make steam enter steel aluminum finned tube heat exchanger more, improved the leaving air temp of steel aluminum finned tube heat exchanger.
When leaving air temp is higher than the temperature of setting, the leaving air temp sensor transfers temperature to electrical signal transfer to intelligent controller, intelligent controller will turn down electric control valve, make steam enter less steel aluminum finned tube heat exchanger, reduce the leaving air temp of steel aluminum finned tube heat exchanger, temperature is controlled in the value range of setting.
The utility model has following effect:
1. the mining warm braw unit of the utility model, the air quantity that provides is larger, and blast is stable, and noise is little, and flames of anger during use is safe.
2. the leaving air temp of the mining warm braw unit of the utility model can be regulated and control as required, and along with Changes in weather, leaving air temp can be adjusted to the temperature of setting automatically.
3. the mining warm braw unit of the utility model adopts steel aluminum finned tube heat exchanger, and heat transfer effect is high, and the leaving air temp accuracy is high, the comparison in equipment energy savings.
4. the new mining warm braw unit of this practicality, type is simple in structure, and manufacture craft is simple, and is easy for installation, takes up an area the space little, therefore very practical.
Description of drawings
Fig. 1 is the mining hot air blower group structure schematic diagram that the utility model proposes.
The specific embodiment
Shown in Figure 1, the utility model is mining warm braw unit, comprise a blower fan 1 that is positioned at casing, cold wind is by passing through first EAT sensor 5 before the blower fan 1, the cold wind that blower fan 1 bloats is by steel aluminum finned tube heat exchanger 2, hot blast by steel aluminum finned tube heat exchanger 2 passes through leaving air temp sensor 3, enters mine; EAT sensor 5 links to each other with intelligent controller 6 by cable with leaving air temp sensor 3.Steam inlet pipeline at steel aluminum finned tube heat exchanger 2 is equipped with electric control valve 4.
When air enters the temperature reduction of blower fan 1, EAT sensor 5 transfers temperature to electrical signal transfer to intelligent controller 6, intelligent controller 6 will be driven large electric control valve 4, make steam enter steel aluminum finned tube heat exchanger 2 more, improve the leaving air temp of heat exchange unit.
When air enters the temperature rising of blower fan 1, leaving air temp sensor 3 transfers temperature to electrical signal transfer to intelligent controller 6, intelligent controller 6 will turn down electric control valve 4, make steam enter less steel aluminum finned tube heat exchanger 2, reduce the leaving air temp of mining warm braw unit, temperature is controlled in the value range of setting.
In sum, the utility model the is mining warm braw unit can be widely used in colliery, iron ore, etc. the mine mouth heating in winter of industry add and pine for, can be made into the mining warm braw unit of various models, will produce good social efficiency and economic benefit if be promoted.
