Description

Technical Field

[0001] The utility model belongs to the technical field of air heaters, in particular to a drum-type indirect-fired air heater. Background Art

[0002] At present, most of the heating devices on the market use boiler water heating systems. However, in large spaces and extremely cold areas, the water heating system has poor adaptability and low heating efficiency. For example, the water system is prone to freezing, causing pipe bursts and damage to equipment. To avoid pipe bursts, it is necessary to heat all the time, wasting energy, especially at night when no one is around. In large spaces, the water heating system dissipates heat quickly and the effect is not obvious. In large spaces, such as warehouses, factories, hangars, etc., the boiler water heating system does not have a ventilation function in summer, and a ventilation system needs to be designed separately. At the same time, the water heating system also needs to design a boiler separately, which occupies a large area. Therefore, a drum-type inter-fired heater is proposed.

[0003] For example, a Chinese patent with publication number CN210580414U discloses an intermittent-fired suspended gas heater device, comprising a shell, a gas tank is fixedly mounted on the back of the shell, an air outlet pipe is fixedly mounted on one side of the gas tank, the other end of the air outlet pipe is fixedly mounted on a gas filter device, an air supply pipe is fixedly mounted on the other end of the gas filter device, and one end of the air supply pipe extends deep into the combustion chamber.

[0004] The existing technical documents have the following problems:

[0005] The existing technical documents have some shortcomings when used, such as: in large spaces, the water heating system has a poor heat dissipation effect, the boiler water heating system does not have a ventilation function in summer, and a separate ventilation system needs to be designed. At the same time, the water heating system also needs a separate boiler design, which results in a large occupied area. Moreover, when the equipment is used outdoors, especially in cold areas, it is easy to affect the inside of the equipment and produce frost and fog, thereby reducing the service life of the equipment. In view of this, we propose a drum-type inter-fired heater. Utility Model Content

[0006] The purpose of the utility model is to provide a drum-type indirect-fired heater to solve the above-mentioned technical problems, so as to achieve the effect of convenient heat dissipation and a smaller space area and increase the service life.

[0007] In view of this, the utility model provides a drum-type intermittent combustion heater, comprising a sheet metal shell, and also includes: a burner connecting plate is fixedly installed on one side of the sheet metal shell, a heat preservation cotton is fixedly arranged on the inner wall of the sheet metal shell, an air outlet is fixedly arranged on the top of the sheet metal shell, a bottom plate is fixedly installed on the bottom end of the interior of the sheet metal shell, a connecting frame is fixedly installed on the top of the interior of the sheet metal shell, a mounting plate is fixedly installed on the bottom of the sheet metal shell, a control box is fixedly installed on one side of the mounting plate, a junction box is fixedly installed on one side of the control box, a mounting frame is fixedly installed between the mounting plates, a bolt is installed through the bottom end of the interior of the mounting frame, a heat exchange fan is fixedly installed between the mounting frames, a base is fixedly installed on the bottom of the mounting plate, and a new air inlet is fixedly arranged on the top of the base.

[0008] Based on the above structure, the whole process is to heat the fresh air without heating the water system, so the possibility of bursting of the heat exchanger of the water system in extremely cold areas is avoided. At the same time, it can be heated at any time to save energy, reduce the overall space occupied by the equipment, and improve practical convenience. The insulation cotton uses thicker high-quality mineral wool for sealing to ensure that the inside of the equipment will not cause fog and frost due to excessively low ambient temperature, which will not affect the life of the equipment.

[0009] Preferably, a connection port is fixedly provided on one side of the burner connection plate, and the shape of the connection port is circular. The burner connection plate is used to increase the sealing of the connection between the combustion heat exchanger and the external pipeline, and the connection port is used to connect the burner.

[0010] Preferably, the bottoms of the bolts are all sleeved with ceramic shock-absorbing pads, which are made of ceramic rubber to avoid damage caused by vibration during the operation of the fan.

[0011] Preferably, a temperature control probe support frame is provided at the bottom end of the connecting frame, and hanging ears are equidistantly installed on the top of the connecting frame. A combustion heat exchanger is fixedly installed on the top of the temperature control probe support frame, and the combustion heat exchanger is used for heat exchange.

[0012] Preferably, an air inlet is fixedly provided on one side of the combustion heat exchanger, and a smoke exhaust port is fixedly provided on the other side of the combustion heat exchanger, so that heat exchange work can be conveniently performed through the air inlet and the smoke exhaust port.

After the equipment is started, the heat exchanger burns and transfers heat. After the temperature is reached, the heat exchange fan is started for heat exchange, and the heated fresh air is transported to the place that needs to be heated to realize the heating function. The whole process is to heat the fresh air, and there is no heating water system, so the possibility of the heat exchanger of the water system bursting in extremely cold areas is avoided. At the same time, it can also be heated at any time, saving energy, reducing the overall space occupied by the equipment, and improving practical convenience.
