[0002] The shell-breaking cylinder on the electrolytic cell in the electrolytic aluminum workshop is used to open a hole on the hard shell surface of the electrolyte in the electrolytic cell for feeding. The existing shell-breaking cylinder is controlled by only one reversing valve, which is collectively referred to as the ordinary shell-breaking cylinder in the industry. It consists of two main components, the ordinary cylinder at the front and the reversing valve at the rear. The existing structure and technology have the defects of the cylinder extending and retracting too fast, the impact force is too strong, and the noise is too loud. The strong impact also reduces the reliability of the cylinder operation. Usually, maintenance is required after 6 months of operation. The cylinder has no perception ability and cannot return in time after breaking the shell surface. It is immersed in high-temperature aluminum liquid for a long time, resulting in severe thermal corrosion of the hammer head. It always runs at a high pressure state, consumes a lot of compressed air, and is energy-intensive and not energy-saving.

[0004] The cited patent documents also have the same problems, such as: the cylinder extends and retracts too quickly, the impact force is too strong, and the noise is too loud. The strong impact also reduces the reliability of the cylinder operation, and it usually needs maintenance after 6 months of operation. The cylinder has no perception ability and cannot return in time after breaking the shell surface. It is immersed in high-temperature aluminum liquid for a long time, which causes serious thermal corrosion of the hammer head. It always runs in a high-pressure state, consumes a lot of compressed air, and is energy-intensive and not energy-efficient. Utility Model Content

A connecting fork 4 is fixedly connected to the free telescopic end of the piston rod 3. The smart valve assembly 5 comprises:

[0034] The smart valve housing 6 is provided with a signal air hole 10 on its front side to facilitate receiving and transmitting electrical signals; shell breaking status valves 9 are symmetrically arranged on both sides to sense and respond to the shell breaking status of the shell breaking cylinder; two reversing valves 12 are installed on the top to switch the air flow direction and realize the extension and retraction action of the cylinder; a main air switch valve cover 15 is arranged on the outer wall of the smart valve housing 6, and a valve body is arranged inside the main air switch valve cover 15.

[0035] The main air switch valve is arranged on one side outer wall of the smart valve housing 6 to control the opening and closing of the main air source, ensuring that the shelling cylinder body 1 consumes compressed air only when needed;

[0036] The shell breaking status valve 9 is arranged on the outer wall on the other side opposite to the smart valve housing 6. The shell breaking status valve 9 can sense whether the shell breaking cylinder body 1 has successfully broken the hard shell surface of the electrolyte, and after sensing the shell breaking state, it triggers the timely retraction of the shell breaking cylinder to reduce the time of the hammer head being immersed in the high-temperature aluminum liquid and reduce the risk of thermal corrosion.

[0037] The time-delay throttle valve 8 is arranged on the bottom surface of the smart valve housing 6, and also has a main air throttle valve 7 and valve port air holes 18 arranged in a triangle;

[0038] The main air throttle valve 7 and the time delay throttle valve 8 are connected to the shell breaking cylinder body 1. By reducing the air supply pressure, the shell breaking cylinder body 1 is operated under a low air pressure state to reduce the operating speed, impact force and operating noise.

[0039] In this embodiment, rectangular notches 13 are provided at the three upper corners of the smart valve housing 6, one of the notches has two valve covers 11, and the other opposite notch has one valve cover 11 and a reset valve 14. A main air inlet hole 16 and two main valve covers 17 are provided on the back outer wall of the smart valve housing 6, which serve as the main air source access point and sealing device.

[0040] In this embodiment, the main air throttle valve 7 and the delay throttle valve 8 work together to adjust the air supply pressure so that the shelling cylinder operates under a low air pressure state.

[0041] In this embodiment, the top surface of the smart valve housing 6 is provided with a plurality of connection holes for connecting the electrical signal of the control cabinet and an operation status detection port of the shell breaking cylinder body 1, so as to monitor and feedback the operation status of the shell breaking cylinder body 1 in real time.

[0042] In this embodiment, the valve cover 11 , the main valve cover 17 and the reset valve 14 together provide sealing protection for the smart valve assembly 5 .

[0043] How it works

[0044] The dedicated smart valve structure of the shelling cylinder of the electrolytic cell, the dedicated smart valve assembly 5 of the shelling cylinder body 1 is in a standby state, the main gas switch valve is closed, the main gas source is not connected, the operator sends a start command through the control cabinet, the connection hole on the top surface of the smart valve housing 6 receives an electrical signal, the main gas switch valve is opened, and the main gas source enters the smart valve through the main gas inlet hole;

[0045] After the main air source enters the smart valve, it first passes through the main air throttle valve 7 and the delay throttle valve 8. These two valves work together to precisely adjust the air supply pressure so that the shelling cylinder body 1 operates under a low air pressure state. This low air pressure state helps to reduce the operating speed, impact force and operating noise of the shelling cylinder body 1, thereby reducing equipment wear and extending the service life;

[0046] The regulated compressed air is distributed into the shell-breaking cylinder body 1 through the valve port air hole 18, pushing the piston rod 3 to move, driving the hammer head connected to the connecting fork head 4 to perform shell-breaking operation on the electrolyte hard shell surface;

[0047] During the shell breaking process, the shell breaking status valve 9 continuously monitors the contact status between the hammer head and the electrolyte hard shell surface. When the hammer head successfully breaks the hard shell surface, the shell breaking status valve 9 immediately senses this change and sends a signal. After receiving the shell breaking signal, the control system inside the smart valve triggers the reversing valve 12 to change the airflow direction, prompting the shell breaking cylinder body 1 to quickly retract the hammer head. This process effectively reduces the time the hammer head is immersed in high-temperature aluminum liquid, greatly reducing the risk of thermal corrosion.

[0048] It should be noted that, in this article, relational terms such as one and two are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".
