Description

Technical Field

[0001] This utility model relates to the field of air circuits for the bottom cover of a four-line extraction tank, and in particular to an optimized interlocking air circuit system for the bottom cover of a four-line extraction tank. Background Technology

[0002] In industrial production, especially in processes involving material extraction, the safe and efficient operation of extraction tanks is crucial. Traditional four-line extraction tank bottom cover pneumatic systems have numerous problems, limiting improvements in production efficiency and safety. Early extraction tank pneumatic systems often employed a simple single-stage control mode, with a three-position four-way manual valve directly connected to the compressed air main. The cylinder actuation was controlled by changing the airflow direction via the manual valve, lacking an effective independent control mechanism between each extraction tank. This meant that a malfunction in one extraction tank often affected the entire pneumatic system, even forcing other normally operating extraction tanks to stop operating, severely impacting production continuity. For example, in some traditional Chinese medicine extraction workshops, a malfunctioning manual valve in one extraction tank, causing compressed air leakage, could lead to unstable pressure throughout the pneumatic system, preventing other extraction tanks from performing extraction operations normally, resulting in material waste and production delays. Furthermore, the frequent use of the manual valve could cause leaks in the valve's seal, resulting in uneven cylinder operation and inability to fully close and lock. To address this issue, the manual valve was replaced with a solenoid valve for directional control. However, the fixed-path control method used in the traditional system makes it difficult to flexibly adjust to different production conditions and process requirements in terms of control precision. Furthermore, the traditional system lacks effective safety protection and fault warning mechanisms. Relying solely on simple mechanical interlocks or manual monitoring for opening and closing the extraction tank's bottom cover is insufficient to promptly detect and handle abnormalities. In the event of a misoperation, such as opening the bottom cover while the extraction tank is in operation, it could potentially lead to serious safety accidents such as material leakage and explosions, threatening personnel lives and company property. Simultaneously, valve malfunctions cannot be promptly reported to operators, hindering timely repair efforts and further exacerbating safety hazards.

[0003] With the development of industrial automation and intelligence, higher requirements have been placed on the gas circuit system of the bottom cover of the four-line extraction tank. There is an urgent need for a new type of gas circuit system that can achieve precise control, efficient operation, and safety and reliability to meet the increasingly complex production needs. Utility Model Content

[0004] The main purpose of this invention is to provide an optimized four-line extraction tank bottom cover interlocking gas circuit system, which solves the technical problems of current gas circuit systems that cannot be accurately controlled, have low efficiency and low safety.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an optimized four-line extraction tank bottom cover interlocking air circuit system, comprising:

[0006] The intelligent precision control module is used to control and select the compressed air delivery channel;

[0007] The dual-stage safety protection solenoid valve module has one end connected to the intelligent precision control module to establish a high-speed data interaction electrical connection, and the other end is connected to the extraction tanks one by one through a dedicated compressed air main pipe to control the opening and closing of the corresponding extraction tanks.

[0008] The four-line extraction tank module includes several sets of extraction tanks and a solenoid valve group module at the front end of each extraction tank.

[0009] The solenoid valve assembly separates the two extraction tanks of the four-wire integrated system. In the preferred embodiment, the four-wire extraction tank module contains at least two extraction tanks, and the extraction tanks and their corresponding solenoid valve assemblies are independent of each other.

[0010] The solenoid valve assemblies are all directly connected to the main compressed air pipe.

[0011] In the preferred embodiment, a communication module is also included, which is located between the intelligent precision control module and the dual-stage safety protection solenoid valve group module. This module is used to receive commands from the intelligent precision control module and to enable bidirectional communication between the two.

[0012] In the preferred embodiment, the dual-stage safety protection solenoid valve assembly module is also equipped with a sensor module, which includes a pressure sensor and a flow sensor to monitor the pressure and flow of compressed air in real time and feed the data back to the intelligent precision control module through the communication enhancement module.

[0013] In the preferred embodiment, the dual-stage safety protection solenoid valve assembly module is also equipped with a local intelligent control unit. When it receives the instruction from the intelligent precision control module, it first performs instruction verification and optimization locally. If an abnormal instruction is detected, it immediately feeds back to the intelligent precision control module for correction through the communication enhancement module; if the instruction is correct, it is executed quickly.

[0014] In the preferred embodiment, an alarm module is also provided. When the opening and closing status of the extraction tank is inconsistent with the control command, such as when a closing command is issued but the extraction tank does not close normally, or when the solenoid valve malfunctions and cannot act according to the command, or when abnormal pressure or flow rate is detected to exceed the set threshold, an alarm is triggered.

[0015] In the preferred embodiment, the alarm module adopts an audible and visual alarm method, with alarm lights and buzzers installed in the central control room and on-site, and alarm information is sent to the user terminal through the communication enhancement module.

[0016] This invention provides an optimized four-line extraction tank bottom cover interlocking air circuit system. The intelligent and precise control module, based on preset production process parameters and real-time monitored air circuit status, uses advanced algorithms and precision control technology to send commands to the control dual-stage safety protection solenoid valve group module. The latter receives the control commands in real time and opens the corresponding solenoid valve, allowing compressed air to enter the corresponding extraction tank through a dedicated compressed air main pipe, thus opening the extraction tank. The solenoid valve group controls the flow of compressed air according to the commands, thereby achieving individual control of the extraction tank. This system enables dynamic adjustment of the compressed air delivery channel according to complex working conditions, ensuring delivery along the optimal path and with high precision, significantly improving the quality and efficiency of the extraction operation.

[0017] When an extraction tank or its corresponding solenoid valve assembly malfunctions, it will not affect the normal operation of other extraction tanks, significantly enhancing the system's stability and reliability and effectively ensuring production continuity. Through the coordinated work of each module, efficient, safe, and stable operation is achieved, providing strong support for the company's production activities and reducing production costs.

[0024] Example 1

[0025] like Figure 1-5 As shown, an optimized four-line extraction tank bottom cover interlocking gas circuit system includes:

[0026] The intelligent precision control module is used to control and select the compressed air delivery channel;

[0027] The dual-stage safety protection solenoid valve module has one end connected to the intelligent precision control module to establish a high-speed data interaction electrical connection, and the other end is connected to the extraction tanks one by one through a dedicated compressed air main pipe to control the opening and closing of the corresponding extraction tanks.

[0028] The four-line extraction tank module includes several sets of extraction tanks and a solenoid valve group module at the front end of each extraction tank.

[0029] The solenoid valve assembly separates the two extraction tanks that are integrated into a four-wire system.

[0030] In the preferred embodiment, the four-line extraction tank module contains at least two extraction tanks, and the extraction tanks (9#, 10#) and the corresponding solenoid valve groups (YV9, YV10) are all independent of each other;

[0031] The solenoid valve assemblies are all directly connected to the main compressed air pipe.

[0032] like Figure 1 As shown in this embodiment, the intelligent precision control module determines the extraction tanks that need to be opened and closed based on preset production process parameters and real-time monitored air path status. It selects the compressed air delivery channel, directs it to the corresponding dual-stage safety protection solenoid valve group module, and sends commands to the control module. The latter receives the control commands in real time, opens the corresponding solenoid valve, and allows compressed air to enter the corresponding extraction tank through a dedicated compressed air main pipe, thus opening the extraction tank. The solenoid valve group controls the flow of compressed air according to the commands, thereby achieving individual control of the extraction tank. This enables dynamic adjustment of the compressed air delivery channel based on complex operating conditions, ensuring delivery along the optimal path and with high precision, greatly improving the quality and efficiency of the extraction operation. Furthermore, when a certain extraction tank or its corresponding solenoid valve group malfunctions, it will not affect the normal operation of other extraction tanks, significantly enhancing the stability and reliability of the system and effectively guaranteeing the continuity of production.

[0033] The entire system, through optimized gas path design and intelligent control, reduces compressed air leakage and energy loss, thereby improving energy utilization efficiency. Simultaneously, the rapid-response control mechanism significantly shortens the opening and closing time of the extraction tank, accelerating the production pace and improving overall production efficiency.

[0034] In this embodiment, the original solenoid valve assembly is as follows: Figure 2 As shown, the improved solenoid valve assembly used is as follows: Figure 3 As shown, new solenoid valves YV9 and YV10 are added as compressed air switches for two solenoid valve groups: solenoid valves YV9 and YV10 are controlled by the operator in the central control room. This embodiment is described based on solenoid valves YV9 and YV10.

[0035] 1) Compressed air supply: The "compressed air" pipeline at the top of the diagram provides the air source for the entire system and is the power basis for the system's operation.

[0036] 2) Solenoid Valve Control: Compressed air enters different solenoid valve groups via solenoid valves YV9 and YV10. YV9 and YV10 act as compressed air switches, controlled by the central control room, determining whether to supply air to the corresponding extraction tank's solenoid valve group. For example, when extraction tank #9 needs to open its bottom cover to discharge slag, the central control room opens YV9, allowing compressed air to enter the subsequent air path.

[0037] 3) Solenoid Valve Assemblies: There are two solenoid valve assemblies, corresponding to extraction tanks #9 and #10 respectively. The solenoid valve assembly corresponding to extraction tank #9 includes Y10, Y20, Y11, and Y21; the solenoid valve assembly corresponding to extraction tank #10 includes Y30, Y40, Y31, and Y41. These solenoid valves are responsible for performing actions such as unlocking, opening, locking, and closing the bottom cover of the extraction tanks. For example, Y10 may control the unlocking of extraction tank #9, and Y20 may control the opening of the bottom cover of extraction tank #9.

[0038] 4) Extraction Tank Operations: Each extraction tank has four corresponding actions: unlocking, opening the lid, locking the cable, and closing the lid. These actions are controlled by the solenoid valves in the corresponding solenoid valve group, which control the flow of compressed air. For example, the unlocking and opening actions of extraction tank #9 are initiated by YV9 and then completed by the corresponding solenoid valve components; the closing and locking actions are handled similarly. The control logic for extraction tank #10 is the same as #9, with YV10 and the corresponding solenoid valve group controlling the corresponding actions.

[0039] Under normal circumstances, YV9 and YV10 are in the off state.

[0040] During operation: When the bottom cover of extraction tank #9 needs to be opened to discharge slag, the operator in the central control room opens the YV9 solenoid valve, and compressed air is introduced into the solenoid valve group of extraction tank #9. Only then can the on-site operator unlock and open the bottom cover of extraction tank #9.

[0041] After the slag discharge is completed, and the steps of closing and locking the lid are completed, the operator in the central control room closes the YV9 solenoid valve and cuts off the compressed air of the solenoid valve group, which effectively prevents operator misoperation, resulting in liquid leakage or equipment accident. The operation steps of other extraction tanks are the same.

[0042] In the four-line integrated structure, the solenoid valve assembly at the front end of each extraction tank plays a crucial role. When the dual-stage safety-protected solenoid valve assembly module switches on compressed air, the compressed air enters the corresponding extraction tank's front-end solenoid valve assembly. Based on its pre-set logic, the current solenoid valve assembly further precisely controls the flow rate and pressure of the compressed air entering the extraction tank, ensuring the extraction tank operates under optimal conditions. Simultaneously, the solenoid valve assemblies separate the two extraction tanks within the four-line integrated structure, enabling independent control and management of each tank and preventing mutual interference.

[0043] In the preferred embodiment, a communication module is also included, which is located between the intelligent precision control module and the dual-stage safety protection solenoid valve group module. This module is used to receive commands from the intelligent precision control module and to enable bidirectional communication between the two.

[0044] In this embodiment, the communication enhancement module employs a high-speed, low-latency communication chip and redundant communication lines to ensure stable and high-speed bidirectional communication between the intelligent precision control module and the dual-stage safety protection solenoid valve assembly module. The dual optimization of hardware and data processing not only enables rapid transmission of commands and feedback information but also allows for data preprocessing and command priority sorting, significantly improving system response speed and achieving real-time control.

[0045] In the preferred embodiment, the dual-stage safety protection solenoid valve assembly module is also equipped with a sensor module, which includes a pressure sensor and a flow sensor to monitor the pressure and flow of compressed air in real time and feed the data back to the intelligent precision control module through the communication enhancement module.

[0046] The dual-stage safety protection solenoid valve module is optimized in both hardware and control logic. On the hardware side, it employs high-sensitivity components and fast-response valve cores, combined with real-time monitoring by pressure and flow sensors. On the control logic side, a local intelligent control unit is set up to verify and optimize commands. Under normal conditions, YV9 and YV10 are closed; during operation, they are opened according to the procedure and closed promptly after completion, eliminating the risk of misoperation and ensuring safe system operation.

[0047] In the preferred embodiment, the dual-stage safety protection solenoid valve assembly module is also equipped with a local intelligent control unit. When it receives the instruction from the intelligent precision control module, it first performs instruction verification and optimization locally. If an abnormal instruction is detected, it immediately feeds back to the intelligent precision control module for correction through the communication enhancement module; if the instruction is correct, it is executed quickly.

[0048] In this embodiment, the local intelligent control unit verifies and optimizes commands. Under normal conditions, YV9 and YV10 are closed; during operation, they are opened according to the procedure and closed promptly upon completion to prevent potential misoperation and ensure safe system operation. If the command is correct, the local intelligent control unit directs the solenoid valve assembly to respond quickly and execute the corresponding action. When an open signal is received, the solenoid valve assembly opens, allowing compressed air from the dedicated compressed air main to flow into the corresponding extraction tank, driving the extraction tank's switching mechanism to open it. When a close signal is received, the solenoid valve assembly closes, cutting off the compressed air supply, and the extraction tank's switching mechanism closes the extraction tank under the action of the reset device. Simultaneously, the dual-stage safety protection solenoid valve assembly module continuously monitors its own operating status and parameters such as compressed air pressure and flow rate in real time, feeding this data back to the intelligent precision control module for real-time monitoring and adjustment.

[0049] In the preferred embodiment, an alarm module is also provided. When the opening and closing status of the extraction tank is inconsistent with the control command, such as when a closing command is issued but the extraction tank does not close normally, or when the solenoid valve malfunctions and cannot act according to the command, or when abnormal pressure or flow rate is detected to exceed the set threshold, an alarm is triggered.

[0050] In the preferred embodiment, the alarm module adopts an audible and visual alarm method, with alarm lights and buzzers installed in the central control room and on-site, and alarm information is sent to the user terminal through the communication enhancement module.

[0051] In this embodiment, when the alarm module detects abnormal equipment status, abnormal command execution, or abnormal gas path parameters, it alerts relevant personnel in the central control room and on-site through audible and visual alarms, and simultaneously sends the alarm information to the user terminal, thereby improving safety protection.

[0052] like Figure 4 The diagram shown is a schematic of the improved interlocking gas circuit control system in this implementation.

[0053] The red sections represent the newly added YV1~YV12 solenoid valve positions, which correspond to the compressed air switches of the solenoid valve groups for extraction tanks #1~#12.

[0054] like Figure 5 As shown, the area within the green dashed box includes the newly added solenoid valves, precision control module, and control circuitry. The local control box is used by personnel to operate the push-button switches to control the corresponding solenoid valves on the solenoid valve assembly to open or close, thereby opening and closing the bottom cover.

[0055] In this embodiment, the operator in the central control room clicks on point 36 corresponding to module D0309 of the automatic control system on the computer, outputting a signal to the relay module, controlling relay 3KA29 to provide 24V voltage to solenoid valve YV9, causing solenoid valve YV9 to change from the closed state to the open state. The control principle of solenoid valves YV1~YV12 is the same.

[0056] This embodiment, through real-time communication and efficient collaboration between the central control room and the field, avoids human error, improves the safety and efficiency of the extraction tank throughout the entire workflow, optimizes the production process, and enhances overall production efficiency.

[0057] In operation, the entire system, through optimized air path design and intelligent control, reduces compressed air leakage and energy loss, improving energy utilization efficiency. Simultaneously, the rapid-response control mechanism significantly shortens the opening and closing time of the extraction tank, accelerating the production pace and improving overall production efficiency. The local intelligent control unit's rapid processing of commands also contributes to improving the system's overall response speed, further enhancing operational efficiency. The alarm module, upon detecting abnormalities, can quickly notify all parties, preventing prolonged production downtime due to equipment failure or abnormal operation, thereby improving production efficiency.

[0058] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
