Automatic constant temperature infrared catalytic combustion heater

Abstract

The invention discloses an automatic constant temperature infrared catalytic combustion heater, which comprises an air inlet, a gas nozzle is installed on the air inlet, the gas nozzle is connected with an air inlet pipe, an air inlet control valve is arranged on the air inlet pipe, and the air inlet control valve includes The temperature control sensing structure, the adjustment structure and the valve control structure connecting the two; the present invention senses the temperature in the breeding shed through the temperature control sensing structure, and converts the temperature change into mechanical deformation through the liquid in the temperature control sensing structure, Then the mechanical deformation is linked with the valve core of the valve control structure, and then the opening or closing of the valve is controlled. Through the control of the air intake of the heater, the heater can automatically adjust the temperature according to the temperature change of the breeding shed. Purpose, the method of adjusting temperature in the present invention does not require external power supply, temperature sensor and data processing center, and the manufacturing cost is low, which can greatly reduce the breeding cost of the breeding factory.

Description

technical field [0001] The invention relates to the field of breeding, in particular to an automatic constant temperature infrared catalytic combustion heater. Background technique [0002] In the breeding process, in order to provide animals with a more comfortable growth environment, heaters are generally used to maintain the temperature of the farm to facilitate the growth of animals. For example, to raise chickens in a greenhouse, it is generally required that the temperature in the shed should not be lower than 18°C ​​and not higher than 35°C. If the temperature is too high, the chickens do not like to move, which is not conducive to growth. If the temperature is too low, the chickens like to crowd together, have a poor appetite, tend to scream and get sick. [0003] Most of the existing heaters are gas-fired infrared heaters. There are two ways to adjust the temperature of this type of heater, one is manual adjustment, and the other is adjustment by using a proportion...

Problems solved by technology

Among them, manual adjustment is to manually open the size of the intake valve, change the supply of gas, make the gas and air mix and burn, and then release heat, so as to achieve the purpose of temperature control, but manual adjustment is inconvenient and inaccurate. , and cannot automatically adjust and other issues; if a proportional control valve is used, the control principle of the proportional control valve is to continuously control the flow, pressure and direction of the intake air in proportion to the control valve according to the input electrical signal, so it must be equipped with an electric control valve. Control components generally include electromagnets, torque motors, and DC servo motors, all of which require an external power supply to drive

In addition, in order for the proportional control valve to control the size of the intake air according to the temperature, it is necessary to set up a corresponding temperature sensor, detect the temperature through the temperature sensor, and then transmit the temperature signal to the data processing center, the data processing center receives the temperature signal, according to the preset A certain fixed temperature corresponds to the opening of the proportional valve, and the output of the electric control element is controlled, and then the opening of the proportional valve is controlled to realize the control of the intake air volume. The whole control process is complicated, and adjusting the temperature in this way will greatly increase the heater Production costs, not applicable to ordinary farms
