The gas mixing chamber is provided with an air inlet, a gas inlet and a gas mixture outlet; the air inlet is connected with the blower; the gas inlet is connected with the gas transmission pipe; the gas mixture outlet is connected with the burner. A hot air chamber and a heated air circulation device comprising a heat exchanger, an air extractor and a hot air grid are arranged in the furnace mantle; the heat exchanger and the air extractor is arranged in the hot air chamber; the heat exchanger is connected with the burning chamber in the hot air chamber; the hot air grid is arranged in the furnace chamber. The utility model is used for not only drying the marine product but also drying and making the fruit dry cargo of dried lychee, dried longan, etc.

Description

The combustion type hot-air drying stove

Technical field

The utility model relates to a kind of drying equipment, relates in particular to a kind of combustion type hot-air drying stove.

Background technology

Existing marine product drying oven structure has a furnace shell mostly, is provided with furnace chamber and electro-heat equipment in the furnace shell, the energy of electro-heat equipment coal commonly used or electric power.It is a large amount of as pernicious gases such as carbon monoxide, sulfide to adopt coal to be that the drying oven of the energy in use can produce, thereby does not meet environmental protection requirement, and can't control furnace temperature automatically, thereby can influence the quality of marine product.And adopt electric power is the drying oven of the energy, though temperature regulating device can be set with automatic control furnace temperature, its load is bigger, and the thermal efficiency is lower, and operating cost is too high and be difficult to enforcement.

Summary of the invention

The purpose of this utility model is at the problems referred to above, and a kind of combustion type hot-air drying stove is provided, and can reduce the pollution to environment to a certain extent, and the combustion gas low price, is convenient to automatic control.

For achieving the above object, the technical solution of the utility model is as follows: the combustion type hot-air drying stove, a furnace shell is arranged, and be provided with furnace chamber, electro-heat equipment and temperature regulating device in the furnace shell; Described electro-heat equipment is a fuel gas buring electro-heat equipment, is made up of a combustion chamber, at least one burner, a gas mixing chamber, an air blast and gas supply pipe, and at least one burner places in the combustion chamber; Gas mixing chamber has air intake, fuel gas inlet and mixed gas outlet, and air intake connects air blast, and fuel gas inlet connects gas supply pipe, and mixed gas outlet is connected with burner; And also be provided with a hot blast chamber and in the furnace shell and comprise that heat exchanger, air exhauster and hot blast delete the heated air circulation device of lattice, heat exchanger and air exhauster are located in the hot blast chamber, and heat exchanger is connected with the combustion chamber that places the hot blast chamber, and hot blast is deleted lattice and is located in the furnace chamber.

Said burner can be pipe burner.

The utility model makes combustion gas in the burner internal combustion owing to adopt said structure, adds hot-air and delivers to furnace chamber by heated air circulation device, and be aided with circulating hot blast and dry marine product.The utility model operating cost is lower, is convenient to automatic control, and less relatively to the pollution of environment.

Description of drawings

Fig. 1 is a structural representation one of the present utility model;

Fig. 2 is a structural representation two of the present utility model.

Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:

The specific embodiment

As shown in Figure 1 and Figure 2, combustion type hot-air drying stove described in the utility model has a furnace shell 1, is provided with furnace chamber 3, fuel gas buring electro-heat equipment, hot blast chamber 14, heated air circulation device, temperature regulating device 4 and reducing gear 13 in the furnace shell 1.The fuel gas buring electro-heat equipment is made up of a combustion chamber 9, two pipe burners 8, a gas mixing chamber 7, an air blast 15 and gas supply pipes 5, bottom, hot blast chamber is located in combustion chamber 9, two pipe burners place in the combustion chamber, gas mixing chamber has air intake, fuel gas inlet and mixed gas outlet, be connected with air blast 15, gas supply pipe 5 and two pipe burners respectively, fuel gas inlet also is provided with electromagnetic valve 6.Heated air circulation device is deleted lattice 2 by heat exchanger 10, air exhauster 12 and hot blast and is formed, and it is indoor that heat exchanger 10 is located at hot blast, and the one end is connected with the combustion chamber, and the other end is connected with smoke exhaust pipe 11; Air exhauster is installed on top, hot blast chamber; Hot blast is deleted lattice 2 and is located in the furnace chamber 3.

During the utility model operation, combustion gas enters in the gas mixing chamber with after the air of being forced by air blast to send into mixes fully by gas supply pipe earlier and enters burner combustion, the heat energy of burning generation is indoor by the heat exchanger heats air at hot blast, and delete lattice by air exhauster and hot blast and in furnace chamber, form hot air circulation, change marine product on the thing frame thereby can dry the furnace chamber inward turning.

The utility model is except that can be used for drying the marine product, can also be used to oven dry manufacture such as lichee do, fruit dried food and nuts such as dried longan.

Claims
