[0022] The water adding main pipe 3 is a hollow circular tubular structure considering the stability and uniformity of water flow. To solve the problem of uneven spraying caused by insufficient water flow in the distal branch pipeline 4, the diameter of the water adding main pipe 3 gradually decreases along the water flow direction, which increases the water pressure and flow rate of the distal branch pipeline 4 by reducing the pipe diameter, thereby ensuring more uniform distribution of system flow. At the same time, the water adding main pipe 3 is connected to an external water source through a water pump 6, which provides stable water flow for the entire system, ensuring the sustainability and reliability of long-term operation of the equipment.

[0023] The water adding main pipe 3 has multiple branch pipelines 4 distributed at equal intervals along its length direction. The branch pipelines 4 are introduced from the pipe wall of the water adding main pipe 3 in a vertical, inclined or radial manner according to the distribution characteristics of the material and the spraying demand, and are arranged at uniform intervals. The arrangement form of the branch pipelines 4 matches the working area of the conveying belt and the characteristics of the material, which can effectively avoid the phenomenon of excessive or insufficient local spraying, and significantly improve the spraying uniformity. The branch pipelines 4 are made of stainless steel or corrosion-resistant alloy materials, which have excellent corrosion resistance and can maintain good structural stability during long-term operation.

[0024] By optimizing the structure of the water supply main pipe 3 and the branch pipes 4, the uniformity and reliability of the spraying system are significantly improved. The water supply main pipe 3 adopts a hollow circular tubular structure, which gradually reduces in diameter along the water flow direction, ensuring that the distal branch pipes 4 obtain sufficient water pressure and flow rate, solving the problem of uneven spraying. This design increases the flow rate by reducing the pipe diameter, meeting the minimum flow rate standard required in water systems, and avoiding the phenomenon of uneven spraying caused by excessively low flow rate.

[0025] The branch pipes 4 are arranged at equal intervals along the length direction of the water supply main pipe 3, and are led out in a vertical, inclined or radial manner according to the material distribution characteristics and spraying requirements, ensuring the uniformity of spraying coverage. This arrangement effectively avoids the phenomenon of excessive or insufficient local spraying, significantly improving the uniformity of spraying.

[0026] In addition, the branch pipes 4 are made of stainless steel or corrosion-resistant alloy materials, which have excellent corrosion resistance, ensuring structural stability during long-term operation, prolonging the service life of the equipment, and reducing maintenance costs.

[0027] The spraying units 5 are arranged at the end of the branch pipes 4 or at equal intervals along the length direction of the branch pipes 4. Each spraying unit 5 includes an electric valve 51 and a nozzle 52, and the nozzle 52 is connected to the branch pipe 4 through the electric valve 51. The electric valve 51 is used to adjust the on-off state of the nozzle 52 to realize precise control of the spraying amount. The jet direction of the nozzle 52 forms an angle of 30° to 90° with the axis of the branch pipe 4, which can optimize the jet coverage range and ensure that the water flow is uniformly distributed on the material surface above the conveyor belt. The electric valve 51 is connected to the control unit 22, and the control unit 22 adjusts the action of the spraying unit 5 in real time according to the instantaneous flow data provided by the belt scale measurement module 1, thereby realizing precise control of the water adding process.

[0028] Further devices also include a humidity sensor 7 arranged at the discharge end of the conveyor belt, which is used to monitor the humidity of the material and transmit the humidity data to the control unit 22. The control unit 22 dynamically adjusts the working state of the spraying unit 5 according to the feedback information of the humidity sensor 7, to ensure that the humidity of the material meets the process requirements, and to avoid affecting the material quality due to excessively high or low humidity. Through the cooperation of the humidity sensor 7 and the belt scale measurement module 1, the device realizes double monitoring of the instantaneous flow and wetness of the material, making the water adding process more intelligent.

[0029] In the multi-point automatic water adding device based on the instantaneous flow of belt scale, the belt scale measurement module 1 selects the PLR-1 type single idler three electronic belt scale of Saimo Electric Co., Ltd. The device has the characteristics of dynamic cumulative error ±0.5% to ±1.0%, and can automatically switch to the normal auxiliary cumulative meter when a weighing sensor fails or is abnormal, ensuring the continuous and reliable operation of the system.

The module provides 8-way differential input, supports multiple input types, has 16-bit resolution and 3000 VDC isolation voltage, and is suitable for industrial measurement and monitoring applications.
