Description

Spiral heat exchange type heating stove

Technical field

The utility model relates to civil heating stove and accessory technical field, is a kind of spiral heat exchange type heating stove.

Background technology

At present, the general heating stove of Shi Yonging, be in body of heater, to be provided with water jacket around the burner hearth welding all around, water jacket generally is to connect in the body of heater by the mode that weld many places, owing to be that the many places pad is arranged, the welding job amount is big, also cause easily and leak, in addition, water jacket be arranged in the burner hearth around, heat exchange area is bigger, heat in a large amount of absorption burner hearths, cause the temperature in the burner hearth low, make bunker coal nonflammable fully, reduced efficiency of combustion, fuel consumption is big, also cause simultaneously and heat up slowlyer as the water of heat exchange medium, form the slow water at low temperature of flowing velocity, make the heating effect relatively poor.

Summary of the invention

The purpose of this utility model provides a kind of spiral heat exchange type heating stove, and it adopts helix tube to replace common water jacket, has reduced the welding job amount, has avoided the generation of the water jacket drainage in the body of heater; Burner hearth internal combustion temperature is raise, and fired coal combustion is abundant, thermal efficiency height, and waste of fuel is little, makes the water temperature quick heating in the helix tube, the water temperature height, hot water flow speed is fast, thereby has improved the heating effect greatly.

For achieving the above object, the utility model is taked following design:

A kind of spiral heat exchange type heating stove, it includes body of heater, middle part in this body of heater is a burner hearth, fire grate is arranged at the bottom of this burner hearth, have the fire door passage in side wall of furnace, it is characterized in that: in burner hearth, be provided with by refractory cement and be coated on helix tube in the burner hearth wall, the conveyor screw of this pipe with spiral pipe and burner hearth are coniform, opening at the spirochetal middle part of pipe with spiral pipe has dehiscing by the fire door passage, fire door place in the burner hearth upper end is provided with the ring-shaped water jacket that is coated by refractory cement, this ring-shaped water jacket one side is communicated with the helix tube upper end by one section adapter, and this ring-shaped water jacket opposite side is communicated with water out adapter.

Between the helix tube of inboard wall of furnace body and refractory cement coating, be provided with pearlite insulating layer.

The lower end of described helix tube is provided with the water supply connector of stretching out from sidewall of the furnace body, is coated with water jacket in the chimney outside of body of heater upper lateral part, and the water out adapter of described ring-shaped water jacket and the lower end of water jacket are connected, and are provided with water out adapter in the upper end of water jacket.

The water out adapter of described water jacket upper end is provided with two, lays respectively at the both sides of chimney, is with outer cover in the outside of water jacket.

This spiral heat exchange type heating stove, the water jacket that replaces existing welding by pipe with spiral pipe, and the conveyor screw of helix tube is coniform and is arranged in the body of heater, water capacity in the helix tube has bigger reduction than existing water jacket, but the surface area of helix tube in body of heater is much higher than water jacket, and helix tube is coated in the refractory cement of burner hearth, makes the outer surface of helix tube obtain heating, simultaneously, pearlite insulating layer also can improve the heat insulation effect of body of heater; Because the conveyor screw integral body of helix tube is coniform, the water capacity that forms every circle more up is more little, and water temperature is then high more, forms higher leaving water temperature.Therefore, the water in the helix tube heats up very fast.After water enters in the helix tube from water supply connector, rapid intensification is also spiraled upwards mobile along helix tube, because the pipeline of helix tube is longer, water in the pipeline constantly is heated intensification in body of heater, behind the ring-shaped water jacket by fire door place, burner hearth upper end, temperature further is enhanced, and the speed of current is also constantly accelerated, the hot water that this high temperature flows fast can improve the water yield and the temperature of ring-shaped water jacket water out adapter; This ring-shaped water jacket water out adapter is connected with the water jacket of chimney outside, also can utilize the waste heat of chimney that the water in this water jacket is incubated, and two water jacket water out adapters of this water jacket upper end can connect radiator and hot water water pipe according to instructions for use.Because temperature height in the burner hearth, fired coal combustion is abundant, thermal efficiency height, and waste of fuel is little, not only economy but also practicality.

The utility model has the advantages that: owing to adopt helix tube to replace common water jacket, reduced the welding job amount, avoided the generation of the water jacket drainage in the body of heater; Burner hearth internal combustion temperature is raise, and fired coal combustion is abundant, thermal efficiency height, and waste of fuel is little, makes the water temperature quick heating in the helix tube, the water temperature height, hot water flow speed is fast, thereby has improved heat exchange heating effect greatly.
