Description

Agricultural straw boiler with safety anti-explosive function

Technical field

The utility model relates to the arcola that a kind of domestic heating is used, and particularly relating to a kind of is fuel and agricultural straw boiler with safety anti-explosive function with the stalk, is to the improvement of existing Agriculture boiler structure, belongs to the boiler manufacturing technology.

Background technology

At present, most of families in rural area are the main fuel of cooking, warming oneself with stalk still, but old-fashioned cooking stove is brick, the straight-through heated kang within doors of its flue, heat utilization efficiency is undesirable, and floor space is excessive, and the middle Room temperature at cooking stove place is cold excessively, and unhygienic, do not meet the requirement of New Countryside Construction.People work out multiple Agriculture boiler for this reason, for example, be disclosed as the Chinese utility model patent " straw boiler " of CN2423503, its body of heater is a rectangular shape, become double-deck water wall by the steel plate seam, it is characterized in that: the front at body of heater is provided with fire door, be provided with kitchen range eye and water outlet tube head above, the water outlet tube head communicates with the interlayer of double-deck water wall, the side is provided with the side flue, is provided with the backwater tube head in the bottom of side, and backwater tube head and double-deck water wall interlayer communicate, the back side is opened wide to the flue collector mouth, is provided with fire grate below.Though this straw boiler that technique scheme provides has the burning a heatable brick bed, heating supply and the function of cooking, but its water outlet tube head be located at body of heater above, influenced the raising of leaving water temperature, its body of heater becomes double-deck water wall by the steel plate seam, make the body of heater can't be to the middle Room at place radiations heat energy, middle Room temperature is cold excessively, will certainly influence the temperature in room, both sides, particularly do not possess the safety anti-explosive device, in use in case because of the air bleeding valve of room heater breaks down can't normal exhaust, recirculated water in the double-deck water wall of boiler furnace is ' boiling ' state again, a large amount of steam that moment produces can make the double-deck water wall or the room heater pipeline burst of boiler furnace because of drainage nowhere, thereby cause the generation of scald accident.

The utility model content

The purpose of this utility model is to improve the defective of existing Agriculture boiler, provides a kind of novel agricultural straw boiler with safety anti-explosive function.It is main fuel that this agricultural straw boiler adopts straw or straw, except that on boiler body, being provided with the water jacket, also be equipped with the safety anti-explosive device, when delivery is given the heating system in the room and high-temperature flue gas is introduced heated kang flue in the room in water jacket, also to the middle Room at place radiations heat energy, Room temperature is improved in making, the indirect temperature of having stablized the rooms, both sides, particularly change the manual exhaust of air bleeding valve in traditional room heater system the pressure limiting of into blast pipe automatic vent, thereby stopped to suppress the generation of the security incident of water jacket on the quick-fried boiler body or room heater pipeline because of gas discharging is untimely, simultaneously, because the gas discharging in time, also accelerated the circulation rate of hot water in the caliduct, made the fast and heat utilization efficiency height of radiator heat conduction in the room.

The technical scheme that the utility model provides is: this agricultural straw boiler with safety anti-explosive function, include boiler body, the bottom of boiler body is provided with fire door, the boiler body end face is provided with the kitchen range eye, boiler body is provided with floss hole, the inwall of boiler body is provided with water jacket, water jacket is provided with water swivel and backwater joint, the inwall bottom of boiler body is provided with fire grate, the last water swivel that is characterized in described water jacket is located at the floss hole place, the backwater joint of described water jacket is located on the sidewall of water jacket bottom boiler body, also include by three-way pipe in the described agricultural straw boiler, blast pipe, the safety anti-explosive device that uncovered water tank and return duct are formed, wherein said three-way pipe respectively with the last water swivel of water jacket, the water inlet pipe and the blast pipe of room heater sheet are connected, the other end of described blast pipe and uncovered water tank are connected, the bottom of uncovered water tank is provided with return duct, and the other end of this return duct and the backwater joint of water jacket are connected.

For better realizing the purpose of this utility model, the water jacket that the inwall of described boiler body is provided with is arranged on the fire door of boiler body, promptly forms half jacket structure for water, is heat conductivility good metal plate under the fire door of boiler body.

For better realizing the purpose of this utility model, the floss hole that described boiler body is provided with is arranged on the sidewall with the boiler body of the corresponding one side of fire door, certainly this floss hole also can be arranged on the sidewall of other face of boiler body, can also be arranged on the end face of boiler body.

In the technique scheme that the utility model provides, the outward appearance of described boiler body is a rectangle, also can be square or circular, can also be other shape and combination thereof.

In the technique scheme that the utility model provides, the water jacket on the described boiler body can adopt full jacket structure for water, also can adopt half jacket structure for water.

Compared with prior art, the beneficial effects of the utility model are:

1. the utility model is provided with the safety anti-explosive device, adopted the pressure limiting of blast pipe automatic vent, thereby stopped to suppress the generation of the security incident of water jacket on the quick-fried boiler body or room heater pipeline because of gas discharging is untimely, simultaneously, because the gas discharging in time, also accelerated the circulation rate of hot water in the caliduct, made the fast and heat utilization efficiency height of radiator heat conduction in the room;

2. when the utility model adopts half jacket structure for water, the position is a heat conductivility good metal plate under the fire door of its boiler body, delivery is given the heating system in the room in water jacket, and when high-temperature flue gas introduced heated kang flue in the room, do not forget to the middle Room at place radiations heat energy yet;

3. the utility model is located at the floss hole place with the last water swivel of water jacket, rather than the top of boiler, is because the temperature at floss hole place is the highest, thus herein on the water jacket hot water temperature in the water swivel the highest;
