Description

Greenhouse heater

technical field

The utility model relates to heating equipment, in particular to a greenhouse heater.

Background technique

With the development of economy and technology, in recent years, the perennial breeding of aquaculture and the off-season planting and sale of vegetables and fruits have improved people's quality of life. The off-season planting of vegetables and fruits generally needs to be done in greenhouses. Various heaters and hot air stoves have also appeared in heating equipment. Some of them use water as the medium to conduct heat and then dissipate heat. This kind of heating equipment requires a certain number of pipes and heat sinks. The installation is complicated and expensive. In addition, during the heat conduction process, the water itself consumes part of the heat energy, and the heat conduction speed is slow. In this way, 40% of the heat energy can not be used and wasted, which increases the cost; some are directly burned to obtain heat, which has the risk of carbon dioxide poisoning to the aquaculture industry, and this method of heating can not keep the room temperature balanced, consumes a lot of energy, and has poor heating effect. Environmental pollution is also relatively large.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a greenhouse heater with simple structure, convenient installation, low cost and good heating effect.

In order to solve the above-mentioned technical problems, the greenhouse warm air stove of the present utility model comprises a furnace body, a furnace is provided in the furnace body, an air inlet and a feed port are provided at the bottom of the furnace, a chimney is provided at the top of the furnace body, and the furnace body is formed by a The large furnace body and the upper small furnace body are composed of an annular heat conduction plate between the large furnace body and the small furnace body and the furnace, and an annular heat conduction plate is provided between the large furnace body and the small furnace body and their respective internal heat conduction plates. In the warm air chamber, the sides of the large furnace body and the small furnace body are respectively provided with an air inlet and an air outlet connected to the warm air chamber, and the outer port of the air inlet is connected to a fan.

The air inlet and the air outlet are arranged on opposite sides of the warm air chamber to communicate with each other, and the air inlet is arranged lower than the air outlet.

A baffle plate is provided at the junction of the large furnace body and the small furnace body in the furnace.

The top of the furnace is provided with a waste heat deflection cover.

With the above structure, the heat energy generated by the combustion of fuel in the furnace can transfer heat to the air in the warm air chamber through the heat conduction plate, and then dissipate the hot air in the warm air chamber through the fan. The fans are connected separately, which can make full use of the heat of the air in the furnace, and directly send heat through the air for heating, so as to achieve the effect of fast transmission, balanced heat dissipation, and efficient heating. Pressure, no blockage, no condensed water; the baffle plate and the waste heat baffle cover can make the rising high-temperature air return downward, so that the high-temperature air stays in the furnace for a longer time, and the heat exchange is more sufficient; the utility model has a simple structure, The design is scientific and reasonable, and the upper and lower heating chambers are used for heating, with high heat exchange efficiency, good heating effect, energy saving and environmental protection.

Detailed ways

As shown in Figure 1, the greenhouse heater of the present invention includes a furnace body, which is composed of a large furnace body 1 at the bottom and a small furnace body 2 at the top. The large furnace body 1 and the small furnace body 2 are internally connected with Furnace 3, the lower part of the furnace 3 is provided with an air inlet 4 and a feed port 5, the top of the small furnace body 2 is provided with a chimney 6, and an annular heat conducting plate 7 is arranged between the large furnace body 1 and the furnace 3, and the small furnace body 2 and the furnace 3 is provided with an annular heat conduction plate 8, an annular warm air chamber 9 is formed between the large furnace body 1 and the heat conduction plate 7, an annular warm air chamber 10 is formed between the small furnace body 2 and the heat conduction plate 8, and the large furnace body The side of 1 is provided with an air inlet 11 and an air outlet 12 communicating with the warm air chamber 9, the outer port of the air inlet 11 is connected to a fan 13, and the side of the small furnace body 2 is provided with an air inlet 14 and an air outlet 15 communicating with the warm air chamber 10, The outer port of the air inlet 14 is connected to the blower fan 16, a baffle plate 17 is provided at the junction of the large furnace body 1 and the small furnace body 2 in the furnace 3, and a waste heat deflector cover 18 is provided on the top of the furnace 3. The air inlet 11 and the air outlet 12 are arranged on the opposite side of the warm air chamber 9 and the air inlet 11 is lower than the air outlet 12, and the air inlet 14 and the air outlet 15 are arranged on the opposite side of the warm air chamber 10 and the air inlet 14 is lower than the air outlet 15.

When in use, fuel is fed into the furnace 3 through the feed port 5, and the fuel burns in the furnace 3 to generate heat, and the heat passes through the heat conducting plate 7 and the heat conducting plate 8 to heat up the air in the warm air chamber 9 and the warm air chamber 10, and then the fan 13 And the fan 16 blows hot air out of the warm air chamber 9 and the warm air chamber 10, and transfers the heat to the greenhouse or the room through the air outlet 11 and the air outlet 15. The air temperature at the air outlet 12 is between 120°C and 200°C. The air temperature in the room is between 80°C and 150°C, so that the temperature of the greenhouse or the room can be increased rapidly, so that the crops or farmed animals can maintain a good growth temperature.
