Description

Technical fields:

[0001] This utility model relates to a water heating control device, and more particularly to a water heating control device for poultry farms. Background technology:

[0002] Heating systems are essential for intensive poultry farms. Current technology utilizes piped hot water circulation to deliver heat into the sheds, achieving the purpose of heating and insulation. Common control methods include circulating pump on / off control and heater on / off control. A common drawback of both methods is that the circulating pump and heater operate independently. When the water temperature is insufficient, the heater blows cold air directly onto the chickens; conversely, when the water temperature rises, warm air is blown onto the chickens. This fluctuating temperature can easily lead to illness in the flock. Even if the chickens don't get sick, it can reduce the feed conversion ratio, thus lowering economic returns. Utility Model Content

[0003] The purpose of this utility model is to address the problem of uneven heating in existing poultry house heating devices by providing a water heating control device for poultry houses, which avoids alternating cold and warm air blowing on the chickens during operation, thereby reducing the chance of the chickens getting sick due to sudden temperature changes.

[0004] This utility model adopts the following technical solution:

[0005] A water heating control device for poultry farms includes a water tank 1, with a drain pipe 3 and a return pipe 4 connected to the upper and lower parts of the water tank, respectively. A circulation pump 2 is installed at the initial section of the drain pipe 3 connected to the water tank. A set of water heating radiators is connected between the drain pipe 3 and the return pipe 4. Each radiator is equipped with a warm air blower to blow warm air from the radiator into the poultry farm. The device is characterized by:

[0006] The water tank outlet is equipped with a water temperature detection probe. w0 Its measured value is used to control the start and stop of the circulating pump P;

[0007] Each radiator is equipped with an inlet water temperature detection probe and an outlet water temperature detection probe, respectively. The measured values ​​are used to control the start and stop of the corresponding heater.

[0008] A set of air temperature detection probes is installed in the poultry house, corresponding to the heating area supplied by the radiator.

[0009] Temperature probes for non-heating areas are installed between the poultry house and adjacent radiators.

[0010] The system is equipped with a controller MCU. Each temperature probe is connected to the controller MCU via an RS485 bus. The measured values ​​from the various temperature probes are transmitted to the controller MCU. The controller MCU runs a control program and issues commands to drive the corresponding switching devices through the connected drive circuit to control the start or stop of the heater and the circulating pump.

[0011] Advantages and effects of this utility model compared with the prior art:

[0012] This device ensures that the water temperature in the radiator is within the required range when the heater is started, preventing cold air from blowing onto the chickens. It effectively prevents alternating hot and cold air blowing and reduces the risk of chickens getting sick from being exposed to cold air. Attached Figure Description
