Description

Technical Field

[0001] This utility model relates to the field of electrolysis equipment technology, specifically to an automated hydraulic distributor for an electrolytic cell extruder. Background Technology

[0002] A hydraulic distributor, also known as a hydraulic distribution valve or hydraulic manifold, is a device used to regulate the flow direction, pressure, and flow rate of hydraulic oil in a hydraulic system. It distributes the pressurized oil supplied by the hydraulic pump to different actuators according to system requirements, enabling independent or coordinated control of multiple hydraulic components. The hydraulic distributor is one of the core components of a hydraulic system, ensuring that each actuator (such as a cylinder or hydraulic motor) in hydraulic equipment receives the required working pressure and flow rate. It is widely used in industrial machinery, aerospace, and automotive manufacturing, playing a crucial role in the stability and efficiency of hydraulic systems.

[0003] An electrolytic cell extrusion press is a device used during the assembly of electrolytic cells to extrude and seal various components, ensuring the overall structural stability and sealing of the electrolytic cell. In electrolytic cell production, it applies appropriate pressure to tightly bond the various components, preventing electrolyte leakage and ensuring the safety and efficiency of the electrolytic cell in subsequent operations. A common extrusion method using an electrolytic cell extrusion press is to tighten the components with a hydraulic cylinder.

[0004] The utility model patent with authorization announcement number CN 220487969 U and patent name "A Hydraulic System for an Electrolytic Cell Extruder" describes an electrolytic cell extruder whose hydraulic distributor controls the cylinder by changing the flow path and flow rate of the hydraulic oil through the position of the valve core. However, the extrusion pressure of the cylinder is adjusted by manually controlling the pressure reducing valve. This method cannot achieve precise pressure control, cannot provide uniform and stable pressure, and will cause poor sealing between the various components of the electrolytic cell, resulting in electrolyte leakage, malfunction of the electrolytic cell, production accidents, and waste of raw materials. Utility Model Content

[0005] To address the aforementioned technical problems, this invention provides an automated hydraulic distributor for an electrolytic cell extrusion press to achieve precise control of the hydraulic cylinder extrusion pressure.

[0006] The technical solution adopted by this utility model is as follows:

[0007] An automated hydraulic distributor for an electrolytic cell extrusion press includes a throttling check valve, a pressure reducing valve, a manual directional valve, a hydraulically controlled check valve, and a safety valve. The automated hydraulic distributor has ports P, T, DR, A, and B. Inlet P of the automated hydraulic distributor is sequentially connected to the throttling check valve, the pressure reducing valve, the manual directional valve, the hydraulically controlled check valve, and the safety valve. The hydraulically controlled check valve and the safety valve are both connected to port A of the automated hydraulic distributor. The manual directional valve is connected to ports B and T of the automated hydraulic distributor. The pressure reducing valve is connected to port DR of the automated hydraulic distributor. A pressure gauge is installed between the outlet of the pressure reducing valve and the manual directional valve. It also includes a PLC control system, a proportional pressure reducing valve, a solenoid ball valve, and a high-pressure shut-off valve. The high-pressure shut-off valve includes high-pressure shut-off valve one, high-pressure shut-off valve two, and high-pressure shut-off valve three. The outlet of the throttling check valve is connected in sequence to high-pressure shut-off valve one, the proportional pressure reducing valve, high-pressure shut-off valve two, and port A of the automatic hydraulic distributor. High-pressure shut-off valve one is connected to the inlet of the proportional pressure reducing valve, and high-pressure shut-off valve two is connected to the outlet of the proportional pressure reducing valve. The outlet of the proportional pressure reducing valve is also connected to pressure sensor two and pressure gauge three. High-pressure shut-off valve three is also connected to the proportional pressure reducing valve. High-pressure shut-off valve three is connected to port DR of the automatic hydraulic distributor.

[0008] The electromagnetic ball valve is connected to port A of the automated hydraulic distributor and high-pressure shut-off valve 2. The electromagnetic ball valve is also connected to the oil tank. Port A of the automated hydraulic distributor is also connected to pressure sensor 1 and pressure gauge 2.

[0009] The PLC control system is electrically connected to the solenoid ball valve, the proportional pressure reducing valve, pressure sensor 1, and pressure sensor 2. Pressure sensor 1 and pressure sensor 2 send pressure signals to the PLC control system, which then controls the solenoid ball valve and the proportional pressure reducing valve.

[0010] Furthermore, a filter is provided between the high-pressure shut-off valve 1 and the proportional pressure reducing valve 7.

[0011] Furthermore, a check valve is provided between the proportional pressure reducing valve and the second high-pressure shut-off valve. The inlet of the check valve is connected to the outlet of the proportional pressure reducing valve, and the outlet of the check valve is connected to the second high-pressure shut-off valve.

[0012] Furthermore, a check valve is installed between the high-pressure shut-off valve II and port A of the automatic hydraulic distributor, and the check valve is connected to the oil tank.

[0013] Furthermore, pressure sensor one and pressure gauge two are connected to the solenoid ball valve.

[0014] Furthermore, pressure sensor one and pressure sensor two, as well as pressure gauge one, pressure gauge two and pressure gauge three, are all connected to shut-off valves.

[0015] The beneficial effects of this utility model are as follows:

[0016] The pressure of the hydraulic cylinder is controlled by a proportional pressure reducing valve controlled by a PLC. The PLC compares the feedback signal from the pressure sensor with the set value and controls the proportional pressure reducing valve and the solenoid ball valve to form a closed-loop control, which enables precise pressure control. This provides uniform and stable pressure to the electrolytic cell extruder, making the seals between the various components of the electrolytic cell more tight, effectively preventing electrolyte leakage, ensuring the normal operation of the electrolytic cell, and reducing production accidents and raw material waste caused by leakage.

The outlet of the throttling check valve 1 is sequentially connected to high-pressure shut-off valve one 8, proportional pressure reducing valve 7, high-pressure shut-off valve two 9, and port A of the automatic oil pressure distributor. The inlet of proportional pressure reducing valve 7 is connected to high-pressure shut-off valve one 8, and the outlet of proportional pressure reducing valve 7 is connected to high-pressure shut-off valve two 9. The outlet of proportional pressure reducing valve 7 is also connected to pressure sensor two 15 and pressure gauge three 13 to detect the oil pressure output after being regulated by proportional pressure reducing valve 7. High-pressure shut-off valve three 10 is also connected to proportional pressure reducing valve 7 and is connected to port DR of the automatic oil pressure distributor. When the pressure is too high, it can reduce the pressure.

[0023] The A port of the automated hydraulic distributor is connected to a pressure sensor 14 and a pressure gauge 12 to detect the oil pressure at the A port of the automated hydraulic distributor; the solenoid ball valve 6 is connected to the A port of the automated hydraulic distributor and the high-pressure shut-off valve 9, and the solenoid ball valve 6 is also connected to the oil tank to unload the oil at the A port of the automated hydraulic distributor.

[0024] The PLC control system is electrically connected to the solenoid ball valve 6, the proportional pressure reducing valve 7, the pressure sensor 14, and the pressure sensor 25. The pressure sensor 14 and the pressure sensor 25 send pressure signals to the PLC control system, which then controls the solenoid ball valve 6 and the proportional pressure reducing valve 7.

[0025] Furthermore, a filter 16 is installed between the high-pressure shut-off valve 8 and the proportional pressure reducing valve 7 to filter impurities in the input oil and ensure the cleanliness of the hydraulic oil.

Pressure sensors 14 and 15 monitor and provide feedback signals to the PLC control system in real time. The PLC control system will then...

Based on the comparison result, the input electrical signal is adjusted, thereby driving the proportional pressure reducing valve 7 to adjust the valve core position and stabilize the outlet pressure of the proportional pressure reducing valve 7 at the set value. The PLC control system compares the pressure signal from port A of the automatic hydraulic distributor, fed back by pressure sensor 25, with the set value.
