Description

Technical Field

[0001] This utility model relates to the field of control combination valve technology, and in particular to an anti-pollution control combination valve for intelligent shelling of aluminum electrolysis cells. Background Technology

[0002] In aluminum electrolysis production, the shell-breaking operation of the electrolytic cell relies on a conventional shell-breaking system. The core of this system consists of a shell-breaking cylinder, a pneumatic air source, and matching valves. The pneumatic air source provides pressure, driving the shell-breaking cylinder to move the hammer head to impact the electrolyte shell surface, thus clearing the material feeding channel. The matching valves control the on / off of the air source and pressure transmission. Some systems have experimented with seated valves to improve their anti-contamination capabilities and optimize sealing performance. However, the high-frequency vibration of the equipment in the existing shell-breaking operation directly causes the connections in this area to gradually loosen, resulting in gaps. Corrosive gases and dust from the aluminum electrolysis workshop can then seep into the valve through these gaps, leading to seal failure. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the high-frequency vibration of the equipment in the existing shelling operation directly leads to the gradual loosening of the connection in this part. To address this, we propose an anti-pollution control combination valve for intelligent shelling of aluminum electrolysis cells.

[0004] To achieve the above objectives, this application adopts the following technical solution: a pollution control combination valve for intelligent shelling of aluminum electrolytic cells, comprising a valve body and a drive execution body installed on one side of the valve body. The drive execution body has a pressure detection body and a logic control chip installed inside. Both ends of the valve body are provided with mounting ports for installing cylinder connectors. A sealing body is fixedly connected to the inner wall of the mounting port. A first reinforcement component and a second reinforcement component are respectively installed on both sides of the inner wall of the mounting port. After the cylinder connector penetrates the sealing body, it is reinforced by the first reinforcement component and the second reinforcement component.

[0005] Furthermore, the sealing body is arranged around the inner wall of the mounting port, and the interior of the sealing body is a hollow structure. The surrounding layout allows the sealing body to form a full circumferential fit with the outer wall of the cylinder connector, eliminating the dead angle of traditional planar seals and blocking potential gaps between the mounting port and the cylinder connector in space.

[0006] Furthermore, the first reinforcement component and the second reinforcement component are symmetrically distributed about the center of the mounting port, and the first reinforcement component and the second reinforcement component have the same composition structure.

[0007] Furthermore, the second reinforcement component includes a mounting groove formed on the inner wall of the mounting port, a reinforcement block body slidably connected to the inner wall of the mounting groove, one end of the reinforcement block body being fitted to the cylinder connector, and the other end being fixedly connected to the mounting block, a push plate body being axially connected to the end of the mounting block away from the reinforcement block body, and a slider body being fixedly connected to the end of the push plate body away from the mounting block.

[0008] Furthermore, the bottom of the mounting groove is provided with an active channel, and the slider body is slidably connected to the inner wall of the active channel. An elastic element is fixedly connected to one side of the slider body, and the end of the elastic element away from the slider body is fixedly connected to the inner wall of the active channel. Through the continuous elastic force of the elastic element, adaptive elastic clamping of the cylinder connector is achieved. Even if the high-frequency vibration causes the connector to shake slightly, the elastic element can compensate by expansion and contraction to make the reinforcing block body fit synchronously, avoiding clamping force failure.

[0009] Furthermore, in the relaxed state of the elastic element, one end of the reinforcing block body protrudes from the opening of the mounting groove, and the reinforcing block body is a component made of rubber material. Rubber material has high elasticity and high friction. The elasticity can buffer the clamping pressure and avoid rigid damage to the cylinder joint, while the friction can further enhance the clamping stability.

[0010] The technical effects and advantages of this utility model are as follows: In this invention, when the equipment enters the shell-breaking operation state and high-frequency vibration is generated, if the vibration causes a slight displacement of the cylinder joint, the elastic element will compensate through expansion and contraction, driving the slider body and push plate body to adjust synchronously, ensuring that the reinforcing block body always fits the cylinder joint, preventing the joint from loosening or shifting. At the same time, the sealing body, with its surrounding structure and internal hollow elasticity, deforms synchronously with the displacement of the cylinder joint, always maintaining a full circumferential seal with the outer wall of the joint, avoiding gaps caused by displacement. The drive actuator monitors the pressure inside the valve in real time, and if an abnormality is detected, it will adjust the operating parameters in time to help ensure the sealing effect. Throughout the process, the drive actuator regulates the operating rhythm, the reinforcing components resist vibration and prevent loosening through elastic clamping, and the sealing body blocks the intrusion of contaminants through elastic fit. All components are interlocked to ensure stable operation of the valve under harsh working conditions. This solves the problem that in existing shell-breaking operations, high-frequency vibration of the equipment directly causes the connection in this part to gradually loosen, thus gradually creating gaps. Corrosive gases and dust from the aluminum electrolysis workshop can then enter the valve through these gaps, leading to sealing failure. Attached Figure Description

[0013] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0014] Reference Figures 1-4 As shown, in order to solve the problem that high-frequency vibration of equipment in the existing shell-breaking operation will directly cause the connection of this part to gradually loosen, thus gradually creating gaps. Corrosive gases and dust from the aluminum electrolysis workshop will then enter the valve through the gaps, leading to sealing failure. The following preferred technical solution is provided: A pollution-resistant control combination valve for intelligent shelling of aluminum electrolytic cells includes a valve body 1 and a drive actuator 2 installed on one side of the valve body 1. The drive actuator 2 has a pressure detection body and a logic control chip installed inside. The device uses the valve body 1 as the core control carrier. The drive actuator 2 installed on one side, with its built-in pressure detection body and logic control chip, provides precise control for intelligent shelling operations. The mounting ports 3 at both ends of the valve body 1 are used to connect to cylinder connectors 4. The sealing body 5 on the inner wall of the mounting port 3, together with the symmetrically distributed first reinforcement component 6 and second reinforcement component 7, constitute a dual protection system of sealing and reinforcement. The cylinder connector 4 needs to penetrate the sealing body 5 and then be reinforced and fixed by the first reinforcement component 6 and the second reinforcement component 7 to ensure that the connection part can resist high-frequency vibration and avoid loosening. The sealing body 5 is arranged around the inner wall of the mounting port 3, and its interior has a hollow structure. This surrounding layout ensures a full-circumferential fit between the sealing body 5 and the outer wall of the cylinder connector 4, eliminating the dead angles of traditional planar seals and spatially blocking potential gaps between the mounting port 3 and the cylinder connector 4. The hollow design gives the sealing body 5 elastic deformation capability. When high-frequency vibration causes slight displacement of the cylinder connector 4, the sealing body 5 can deform itself to synchronously fit the outer wall of the connector, preventing displacement from causing the sealing surface to detach and creating new gaps. Compared to traditional seals, the surrounding structure increases the sealing area and significantly enhances the sealing performance. The elastic deformation of the hollow design can completely offset the displacement caused by vibration, reducing the intrusion channels of corrosive gases and dust from the source, while also preventing wear of rigid seals due to vibration. The first reinforcing component 6 and the second reinforcing component 7 are symmetrically distributed about the center of the mounting port 3, and their structures are completely identical. This symmetrical distribution ensures that the clamping force of the two components on the cylinder connector 4 is evenly applied to both sides of the connector, preventing uneven force that could cause connector misalignment or tilting. This ensures that the cylinder connector 4 remains coaxial with the mounting port 3, maintaining a uniform fit with the sealing body 5. The identical structural design ensures consistent reinforcing force and synchronized vibration response between the two components, preventing loosening of the connection due to unilateral reinforcement failure. The balanced clamping force improves the connection stability between the cylinder connector 4 and the mounting port 3, resisting high-frequency vibration and effectively preventing the connector from gradually loosening due to long-term vibration. Simultaneously, it ensures that the sealing body 5 is always under uniform pressure, avoiding gaps caused by insufficient local sealing pressure, further enhancing the overall sealing effect. The mounting groove 71 of the second reinforcing component 7 is opened on the inner wall of the mounting opening 3 to provide installation space for internal components; the reinforcing block body 72 is slidably connected to the inner wall of the mounting groove 71, one end of which is attached to the outer wall of the cylinder connector 4 to directly provide clamping force, and the other end is axially connected to the push plate body 74 through the mounting block 73. The end of the push plate body 74 away from the mounting block 73 is fixed to the slider body 75. The slider body 75 is slidably connected to the movable channel 76 at the bottom of the mounting groove 71, and one side of the slider body 75 is fixed to the inner wall of the movable channel 76 through the elastic element 77. When the cylinder connector 4 is inserted into the mounting port 3, it compresses the reinforcing block body 72 into the mounting groove 71. The reinforcing block body 72 pushes the push plate body 74 through the mounting block 73, causing the slider body 75 to slide along the movable channel 76 and compress the elastic element 77. The reaction force of the elastic element 77 is transmitted along the slider body 75, the push plate body 74, the mounting block 73, and the reinforcing block body 72, ensuring that the reinforcing block body 72 is always tightly attached to the outer wall of the cylinder connector 4, forming a continuous clamping force. Through the continuous elastic force of the elastic element 77, the cylinder connector 4 is adaptively and elastically clamped. Even if the high-frequency vibration causes slight shaking of the connector, the elastic element 77 can compensate for the expansion and contraction to keep the reinforcing block body 72 in contact synchronously, avoiding clamping force failure. The sliding connection structure avoids rigid collision between the reinforcing block and the connector, ensuring the reinforcement effect and preventing scratches on the outer wall of the cylinder connector 4, thus reducing maintenance costs. In the relaxed state of the elastic element 77, one end of the reinforcing block body 72 protrudes from the opening of the mounting groove 71; and the reinforcing block body 72 is made of rubber. This protruding design in the relaxed state allows the cylinder connector 4 to immediately contact the reinforcing block body 72 when inserted into the mounting port 3, automatically triggering the clamping action without the need for additional tools or operations. The rubber material has high elasticity and high friction; the elasticity buffers the clamping pressure, preventing rigid damage to the cylinder connector 4, while the friction further enhances clamping stability, preventing the connector from slipping during vibration. Simultaneously, the rubber material fills the tiny gaps between the reinforcing block and the connector, helping to improve sealing. The automatic reinforcement design significantly improves installation efficiency; the elasticity and high friction characteristics of the rubber material ensure both reinforcement stability and connector protection, while the auxiliary sealing function further reduces the intrusion path of corrosive gases and dust.

[0015] Specifically, taking the valve body 1 as the basic carrier, the drive actuator 2 on one side of it has a built-in pressure detection body and logic control chip. During operation, it will output control signals according to the shell-breaking requirements to regulate the valve body 1, providing intelligent operation guarantee for the entire device. When connecting the cylinder connector 4, it needs to be aligned with the mounting ports 3 at both ends of the valve body 1. First, it passes through the sealing body 5 which is set around the inner wall of the mounting port 3. The hollow structure inside the sealing body 5 will first form a preliminary fit with the outer wall of the cylinder connector 4, laying the foundation for subsequent sealing. As the cylinder connector 4 continues to be inserted, it will compress the first reinforcing component 6 and the second reinforcing component 7, which are symmetrically distributed on the inner wall of the mounting port 3. The two components have the same structure and move synchronously. The outer wall of the cylinder connector 4 first contacts the rubber reinforcing block body 72 protruding from the mounting groove 71, pushing the reinforcing block body 72 to retract into the mounting groove 71. At this time, the reinforcing block body 72 drives the push plate body 74 to rotate through the mounting block 73. The push plate body 74 then pushes the slider body 75 to slide along the active channel 76, thereby compressing the elastic element 77 on one side of the slider body 75. The elastic element 77 generates a reaction force after being compressed, which is transmitted to the reinforcing block body 72, so that the reinforcing block body 72 fits tightly against the outer wall of the cylinder connector 4, forming a continuous clamping. When the equipment enters the shell-breaking operation state, high-frequency vibration is generated. If the vibration causes a slight displacement of the cylinder joint 4, the elastic element 77 will compensate through expansion and contraction, driving the slider body 75 and the push plate body 74 to adjust synchronously. This ensures that the reinforcing block body 72 always fits the cylinder joint 4, preventing the joint from loosening or shifting. At the same time, the sealing body 5, with its surrounding structure and internal hollow elasticity, deforms synchronously with the displacement of the cylinder joint 4, always maintaining a full circumferential seal with the outer wall of the joint, avoiding gaps caused by displacement. The drive actuator 2 monitors the pressure inside the valve in real time. If an abnormality is detected, it will adjust the operating parameters in time to help ensure the sealing effect. Throughout the process, the drive actuator 2 regulates the operating rhythm, the reinforcing components resist vibration and prevent loosening through elastic clamping, and the sealing body 5 blocks the intrusion of contaminants through elastic fitting. All components are interlocked to ensure stable operation of the valve under harsh working conditions. This solves the problem that in existing shell-breaking operations, high-frequency vibration of the equipment directly causes the connection in this part to gradually loosen, thus gradually creating gaps. Corrosive gases and dust from the aluminum electrolysis workshop can then enter the valve through these gaps, leading to sealing failure.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
