Description

Technical Field

[0001] The invention relates to the technical field of feed valves, in particular to a full-automatic feed valve system. Background Art

[0002] A feed valve (also called a feed valve or feed gate) is a valve used to control the flow of granular materials or fluids into equipment, pipes or containers. It is mainly used in industrial processes to accurately regulate the inflow of materials. Feed valves are widely used in industries such as chemical, mining, food processing, and pharmaceuticals.

[0003] In the prior art, people often use a cylinder to control the movement of a valve plate inside a feed valve and realize the opening and closing of the feed valve.

[0004] However, in actual use, if the movement of the cylinder is not smooth enough or the response is slow, the valve position will be inaccurate, thus affecting the flow control. At the same time, solid granular materials or high-viscosity fluids may affect the flow control of the valve. Granular materials may cause the valve to get stuck, affecting the accuracy of its opening and closing. In addition, unstable pressure of the air source will also cause unstable movement of the cylinder, thus affecting the control accuracy of the valve. In view of this, we propose a fully automatic feeding valve system. Summary of the invention

[0017] Working principle: When using this device, it needs to be connected to the feed pipe and the valve plate is zero-position detected. At this time, the position sensor will detect the angle information of the valve plate opening and closing axis and perform zero-position calibration. At this time, the material waiting to be fed can be put in, and the pressure sensor above the valve plate will detect the quality of the solid material above it and provide real-time feedback to the control panel; when the system receives the feed instruction, the drive motor starts to work, drives the valve plate opening and closing axis to rotate through the coupling, and then controls the opening and closing of the valve plate. At this time, the control algorithm in the control panel will calculate the opening and closing time of the valve plate according to the sensor information of the external material level sensor and the pressure sensor. The calculation process is as follows:

[0018] The fluid flow rate is calculated using the flow formula Q = A·v, where Q is the flow rate, A is the opening area of ​​the valve, and V is the fluid flow rate.

[0019] Calculate volume: According to the volume formula of fluid V = Q t, where V is volume, Q is flow rate, and t is time.

[0020] To calculate time: Divide the required volume by the flow rate Get the time when the valve is fully opened and closed.

[0021] At the same time, after a single valve plate operation, the purification chamber of the air intake treatment device is connected to the drive motor through a metal tube, and the airflow of the external air supply device is used to cool the metal tube to assist in heat dissipation, thereby reducing the heat generated by the motor during long-term braking movement. The filter plate will filter the gas entering the valve housing. In addition, aerodynamics will also drive the impeller to rotate. During the rotation of the impeller, the bristles on the brush plate will clean the surface of the filter plate to prevent impurities in the gas from affecting the quality of the material inside the valve housing.

[0022] The air chamber of the anti-sticking device injects compressed air into the sleeve through the air inlet pipe. Under the action of air pressure, the piston rod pushes the hidden plate as a whole to extend toward the inside of the valve shell. At the same time, the air nozzle on the hidden plate is aimed at the inner wall of the valve shell and outputs gas, thereby blowing away the material that may adhere to the valve plate and the valve shell. In this way, even when processing high-viscosity solid particulate materials, it can prevent the material from adhering to the feed pipeline or the inner wall of the valve shell and affecting the final feed amount. After the intermittent air intake and blowing are completed, due to the loss of air flow thrust, the spring at the end of the sleeve will pull the hidden plate toward the inner wall of the valve shell through its own elastic force and re-embed it into the inner wall of the valve shell to avoid blocking the material during its normal falling process and to prevent the material from adhering to its air nozzle.

[0023] The touch screen and control buttons on the control panel can realize precise control of the fully automatic feeding valve system. The operator can set parameters such as feeding amount and feeding speed according to actual needs, and monitor the working status of the valve in real time. When the system detects an abnormal situation, such as abnormal material quality detected by the pressure sensor or excessive deviation of the valve plate position detected by the position sensor, the system will automatically issue an alarm and take corresponding measures, such as stopping feeding or adjusting the opening and closing angle of the valve plate, to ensure the stability and safety of the entire feeding process.

[0024] The present invention provides a fully automatic feeding valve system, which has the following beneficial effects:

[0025] 1. The present invention can realize precise control of the feeding process according to the pressure sensor and the external material level sensor through the arranged pressure sensor, valve plate opening and closing shaft, position sensor, control panel and coupling, thereby ensuring the stable feeding of materials and avoiding material waste or production interruption due to improper operation or equipment failure. At the same time, the feeding process is not easily affected by factors such as air pressure by controlling the motor.

[0026] 2. The hidden plate, air bin, air inlet pipe, air nozzle, piston rod and sleeve provided in the present invention can effectively prevent the material from adhering to the feed pipeline or the inner wall of the valve housing when processing high-viscosity solid particle materials, thereby ensuring smooth feeding and accurate feeding amount. The telescopic action of the hidden plate cooperates with the blowing function of the air nozzle to ensure that the cleanliness of the equipment and the quality of the material are not affected, and after completing a single blowing process, the hidden plate will automatically retract to avoid it affecting the normal unloading process.

[0027] 3. The present invention can effectively filter the gas entering the valve housing through the connection block, purification chamber, rotating shaft, impeller, brush plate, and filter plate, ensuring the purity of the gas. At the same time, the rotation of the impeller drives the brush plate to clean the filter plate, avoiding the accumulation of impurities on the surface of the filter plate, extending the service life of the filter plate, and improving the filtering efficiency. In addition, the design of the purification chamber allows the gas to be fully purified before entering the valve housing, thereby ensuring the stable operation of the entire feeding system and the purity of the material.
