Technical field
A kind of coalmine ventilation heater is the utility model is related to, belongs to coalmine ventilation technical field.
Background technology
In colliery, ventilating system is one of most important system in safe coal production.The Northeast of China room in the winter time
Outer temperature many places are indivedual local sometimes in subzero 40 DEG C at night in subzero less than 20 DEG C.Due to very cold, the Northeast
Colliery need in the winter time using boiler heating produce vapor, then heated using heat air delivery in blower fan phase mine.
With the continuous improvement of environmental requirement, heated using boiler, it is necessary to reequiped to boiler, meet environmental requirement, so
Cost is considerably increased, and is heated using steam, fan leaf easily freezes, and the operation to my fan brings very big pressure,
Energy consumption also increases, and is unfavorable for safeguarding.
Utility model content
To solve technical problem existing for prior art, the utility model provides a kind of simple in construction, environmental protection, heating effect
Rate is high, the coalmine ventilation heater being aerated using oil heating air.
To achieve the above object, technical scheme is coalmine ventilation heater used by the utility model, including air
Heater, blower fan is installed on the air heater, the inlet of the air heater passes through oil inlet pipe and deep fat casing
Oil-out be connected, the liquid return hole of air heater is connected by oil return pipe with the oil inlet of deep fat casing, the deep fat
Electric heater unit is provided with casing, is provided with the oil inlet pipe into oil control valve, oil return control is provided with the oil return pipe
Valve and oil strainer processed, are additionally provided with oil circulating pump on the oil return pipe, the blower fan, electric heater unit and oil circulating pump with
Electrical control cubicles are connected, and the inlet and liquid return hole of the deep fat casing are provided with stop valve.
Preferably, in addition to repairing casing, the oil return pipe of the repairing casing are connected with oil inlet pipe, the repairing casing
Oil inlet pipe be connected with oil return pipe, be provided with repairing control valve on the oil inlet pipe and oil return pipe of the repairing casing.
Preferably, it is additionally provided with level instruction device on the repairing casing.
Preferably, the deep fat casing, be provided with thermometer on oil return pipe, also set up discharge on the deep fat casing
Manage, exhaust-control valve is provided with the delivery pipe.
Compared with prior art, the utility model has following technique effect：The utility model is simple in construction, user
Just, air is heated using deep fat, heat air delivery is then carried out by blower fan, the thermal efficiency is high, and energy consumption is low, and energy-saving ring
Protect, greatly reduce operating cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order that technical problem to be solved in the utility model, technical scheme and beneficial effect are more clearly understood, with
Lower combination drawings and Examples, the utility model is further elaborated.It is it should be appreciated that described herein specific real
