Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture heating, and in particular relates to an indirect-fired heater for aquaculture. Background Art

[0002] Breeding refers to the act of cultivating and breeding animals and plants. Breeding includes livestock breeding, poultry breeding, aquaculture and special breeding species. The breeding room needs to be heated, and a gas heater can be used. The main function of the gas heater in the breeding room is to provide a warm environment for the farm and ensure the healthy growth of animals. This equipment raises the temperature in the farm by emitting warm air, thereby creating an environment suitable for animal growth. However, the existing breeding room heating adopts direct combustion, which will directly discharge harmful substances into the house, causing impact. Therefore, a gas heater for breeding is proposed.

[0003] The above patent has the following problems:

[0004] Compared to existing farm gas heating, which typically uses direct combustion, this combustion consumes indoor oxygen and discharges harmful smoke into the shed, which has a certain negative impact on livestock. Furthermore, the existing technology increases ventilation to exhaust the hot air indoors, resulting in energy loss and reducing the efficiency of the device. In view of this, we propose an indirect-fired heater for livestock farming. Utility Model Content

[0005] The purpose of the utility model is to provide an indirect-fired heater for aquaculture in order to solve the above-mentioned technical problems, so as to prevent smoke from being discharged into the room and causing energy loss.

[0006] In view of this, the utility model provides an indirect-fired heater for breeding, comprising a casing, and further comprising: a heat exchange fan fixedly mounted on one end of the casing, a wind pressure detector fixedly mounted on the bottom of the heat exchange fan, a high-temperature protector fixedly mounted on the bottom of the wind pressure detector, a heat exchange tube fixedly mounted on one side of the high-temperature protector, the heat exchange tube having a serpentine structure, a fresh air inlet fixedly mounted on the other side of the heat exchange fan, a smoke exhaust port fixedly mounted on one end of the fresh air inlet, a gas inlet fixedly mounted on the other side of the smoke exhaust port, a gas valve fixedly mounted on the other side of the gas inlet, and a combustion fan fixedly mounted on the bottom of the gas valve.

[0007] Based on the above structure, heating can be carried out through the heat exchange fan. When there is a demand for heating, the combustion fan starts running. After the ignition is successfully carried out, the high-temperature flue gas heats the heat exchange tube, and the heat exchange fan starts running. The wind pressure detector is used to determine the wind pressure to ensure the normal operation of the heat exchange fan. The heat exchange fan blows out the high-temperature heat on the surface of the heat exchange tube in the form of warm air. When used in conjunction with the intermittent combustion method, the fresh air inlet is installed on the top, and the smoke exhaust port can discharge the smoke to the outside. The harmful smoke after combustion will not be discharged into the house and will not affect the poultry and livestock. The fresh air inlet and the smoke exhaust port can be connected to the external pipe to bring the combustion air from the outside and the smoke is discharged outdoors. The gas valve is opened and the heat exchange fan will run after normal combustion. There is no need to increase ventilation, which will not cause energy loss and increase the working efficiency of the device.

[0008] Preferably, hinges are movably installed on the sides of the casing, and side panels are fixedly installed on the bottoms of the hinges, which can be opened to facilitate cleaning of dirt on the heat exchange tubes.

[0009] Preferably, an air outlet is fixedly provided on one side of the casing, and upper and lower louvers and horizontal louvers are provided in the air outlet to facilitate adjustment of the air outlet direction.

[0010] Preferably, an electrical box is fixedly mounted on the bottom of the gas valve to facilitate the control of ignition and fan operation.

[0011] Preferably, a burner is fixedly mounted on one side of the electrical box to facilitate combustion, and the flame and high-temperature flue gas enter the heat exchange tube.

[0012] Preferably, a manifold is fixedly provided on the other side of the burner to facilitate the entry of gas into each burner.

[0013] Preferably, an ignition needle is fixedly provided on one side of the manifold, and a flame detection needle is fixedly installed on one end of the ignition needle to perform ignition work and detect whether the flame is successfully transmitted.

[0014] The beneficial effects of the utility model are:

[0015] 1. The indirect-fired heater for breeding can be used to start the combustion fan when there is a demand for heating. After the ignition is successful, the high-temperature flue gas heats the heat exchange tube, and the heat exchange fan starts to run. The wind pressure detector is used to determine the wind pressure to ensure the normal operation of the heat exchange fan. The heat exchange fan blows out the high-temperature heat on the surface of the heat exchange tube in the form of warm air. It is used in conjunction with the indirect-fired method. The fresh air inlet is installed on the top, and the smoke exhaust port can discharge the smoke to the outside. The harmful substances after combustion will not be discharged into the house and will not affect the poultry and livestock.

[0016] 2. The indirect-fired heater for breeding can utilize the fresh air inlet and smoke exhaust port to be connected to the external pipe, so that the combustion air comes from the outside and the smoke is discharged outdoors. The gas valve is opened and the heat exchange fan will only operate after normal combustion. There is no need to increase ventilation, which will not cause energy loss and increase the working efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS
