Description

Technical Field

[0001] This utility model relates to the field of vent valve control, and in particular to a foolproof interlock device for preventing forgetting to close a batching vent valve. Background Technology

[0002] In industrial production processes, the vent valve (Degassing Valve) of the batching system is a key component for ensuring process safety, product quality, and production efficiency. Its importance is mainly reflected in the following aspects:

[0003] 1. Ensure production safety

[0004] During ingredient preparation, mixing, or reaction processes, temperature changes or chemical reactions may generate gases, leading to increased system pressure. Vent valves release pressure promptly, preventing containers, pipes, or reaction vessels from deforming, rupturing, or even exploding due to overpressure. Some raw materials (such as industrial-grade white oil and PE powder) may contain volatile organic compounds (VOCs) or trace amounts of sulfides; vent valves remove these gases, preventing poisoning or explosion risks. In food and pharmaceutical production, vent valves prevent residual oxygen from causing oxidation and deterioration of raw materials.

[0005] 2. Improve product quality

[0006] When mixing PE powder and white oil, stirring or heating may introduce air, forming bubbles that affect the density (e.g., plastic granules) or appearance (e.g., cosmetic creams). Vent valves (especially vacuum vent valves) can effectively degas the mixture, improving its uniformity and stability. Polyethylene (PE) and white oil may oxidize and degrade at high temperatures; vent valves can remove oxygen, extending product lifespan (e.g., food packaging materials, cosmetic shelf life).

[0007] 3. Optimize production processes

[0008] In continuous production processes such as plastic granulation and cosmetic emulsification, vent valves can reduce downtime for cleaning air bubbles or adjusting pressure, thereby increasing production capacity. Atmospheric pressure venting: Used in ordinary mixing processes to remove air. Vacuum degassing: Used in high-end products (such as pharmaceutical-grade white oil and high-precision PE film) in conjunction with a vacuum pump for deep devolatilization.

[0009] In existing production processes, venting operations primarily rely on operator control. When venting is needed, the operator opens the vent valve; after venting, the operator closes the valve. However, this method heavily depends on the operator's responsibility and adherence to operating procedures to ensure proper closure. Human error is difficult to completely avoid. If the operator forgets to close the vent valve after completing the batching and venting process, material leakage may occur, leading to material waste, increased production costs, potential environmental pollution, and even safety accidents. The consequences of forgetting to close the vent valve are particularly severe on production lines with high material precision requirements and continuous production processes. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] like Figure 1-2 As shown in the figure, the non-foolproof interlocking device for the batching vent valve provided in this embodiment includes a control valve 1, a detection module, a control module, an alarm module, etc. One end of the control valve 1 is connected to the conveying pipe 2 used for conveying batching materials, and the other end is provided with a vent port 6. The control valve 1 is opened when venting is required and closed after venting is completed. The control valve 1 can be a solenoid valve, ball valve, gate valve, or other structure capable of opening and closing. The control valve 1 and the conveying pipe 2 are fixedly connected via a connecting flange. A sealing gasket can be provided at the connection position between the control valve 1 and the conveying pipe 2 to ensure the sealing performance of the connection position.

[0035] Please see Figure 1-2 In one embodiment of this utility model, the detection module can be disposed within the delivery pipe 2. The detection module is used to acquire pressure data and / or flow data within the delivery pipe 2; specifically, it can be disposed within the delivery pipe 2 near the control valve 1. The detection module includes a pressure sensor and / or a flow sensor disposed within the delivery pipe 2. Preferably, at least one pressure sensor and one flow sensor are disposed simultaneously within the delivery pipe 2 to collect pressure and flow information within the delivery pipe 2 and upload it to the control module for determining whether the purging operation is complete. The specific model of the sensor is not limited, as long as it can achieve the data acquisition function.

[0036] Please see Figure 1-2In one embodiment of this utility model, the control module is connected to the detection module and is used to control the opening and closing of the control valve 1. As an example, the control module can use a programmable logic controller (PLC) as the control core to receive signals from the sensor detection module and analyze and process the signals. As an example, the control logic design of the control module can be as follows: the vent valve is only allowed to open after the batching system issues a clear venting command; during the venting process, if the liquid level or flow rate fluctuates abnormally and exceeds the set normal range, the control system immediately activates an alarm and attempts to close the vent valve; after the venting operation is completed, if the vent valve is not closed within a specified time, the control system automatically controls the actuator to close the vent valve and continuously issues an alarm signal until the operator confirms the handling.

[0037] Please see Figure 1-2 In one embodiment of this utility model, the alarm module is used to issue alarm information according to the instructions of the control module. The alarm module includes a buzzer and / or a warning light to issue a valid alarm message upon receiving instructions from the control module.

[0038] Please see Figure 1-2 In one embodiment of this utility model, the specific structure of the control valve 1 is not limited. As an example, the control valve 1 includes a valve body, a valve core, and a valve stem. The valve core is disposed within the valve body to change the opening and closing state of the control valve 1. The valve stem is fixedly connected to the valve core to drive the valve core to rotate. A handle 3 is fixedly connected to the valve stem. The handle 3 facilitates manual operation of the control valve 1. Furthermore, a drive assembly is provided. The drive assembly drives and connects to the valve stem to drive the valve stem to rotate. The drive assembly is connected to the control module. When it receives a command from the control module, it can drive the valve stem to rotate, thereby driving the valve core to rotate and closing the control valve 1. The drive assembly can be an electric drive structure, such as a servo motor. The output shaft of the motor can be directly connected to the valve stem, or connected to the valve stem through a certain transmission assembly.

[0039] Please see Figure 1-2 In one embodiment of this utility model, a branch pipe 4 can be connected to the side of the conveying pipe 2. The end of the branch pipe 4 away from the conveying pipe 2 is closed. The branch pipe 4 can be used to place the sensor into the conveying pipe 2, and at the same time, facilitates the maintenance and replacement of the sensor. A housing 5 can be provided at the end of the branch pipe 4 away from the conveying pipe 2, and the control module is disposed in the housing 5. The housing 5 can be detachably connected to the branch pipe 4. The housing 5 closes the branch pipe 4 and provides an installation position for the control module. Specifically, the housing 5 includes a detachably connected upper cover and a lower cover, which together form an installation cavity.

[0040] The working principle of this utility model:

[0041] Installation and Commissioning: Fix the pressure sensor and flow sensor in the appropriate positions on the vent valve pipeline according to the correct installation method, seal the flange connection to prevent leakage, and ensure accurate detection of pressure and flow signals; connect the electric actuator (i.e., power unit) to the vent valve to ensure smooth valve stem movement; install the control module and alarm module inside or near the operation console in a location convenient for operation and maintenance, and connect the wiring between each module; commission the entire device, set the pressure and flow thresholds, and the logic parameters of the control module, to ensure normal communication between modules and accurate function implementation.

[0042] When a batching and venting operation is required, the operator issues a venting command on the control console. Upon receiving the command, the control module controls the electric actuator to open the venting valve. During the venting process, pressure and flow sensors monitor the pressure and flow data in the pipeline in real time and transmit the data to the control module. When venting is complete and the pressure and flow in the pipeline drop to the set threshold range, the sensors transmit corresponding signals to the control module. If the venting valve is not closed at this time, the control module immediately sends an alarm command to the alarm module and simultaneously controls the electric actuator to close the venting valve. After hearing the alarm sound or seeing the alarm light, the operator can promptly check the status of the venting valve. If a malfunction occurs during the automatic closing process, manual intervention can be performed.

[0043] This application incorporates a control module and a detection module to monitor the pressure and flow rate within the delivery pipe 2, thereby determining whether the venting operation is complete and monitoring the vent valve's closure status. It can promptly detect and issue an alarm if the vent valve is left open after the venting operation is complete. Furthermore, it can automatically close the vent valve, reducing reliance on operators, mitigating the impact of human error, effectively preventing material leakage due to the vent valve being left open, reducing the probability of safety accidents, and ensuring the safety of production personnel and facilities. Simultaneously, it prevents material waste and reduces additional costs such as cleanup and equipment repair due to material leaks. It also ensures the normal operation of the batching system, preventing production continuity disruptions caused by vent valve issues, and improving production efficiency and product quality.
