The barrel module 1 is usually made of high-strength, corrosion-resistant materials, such as stainless steel or special alloys. During the manufacturing process, the material will undergo precise cutting, welding and machining to ensure that it can withstand high pressure and has sufficient structural strength and durability. The interior of the barrel module 1 should be polished to reduce material residue and facilitate cleaning. The barrel module 1 serves as the basic framework of the entire system, providing a stable support and a closed environment for accommodating other components and materials. Its design ensures that it can withstand the influence of internal pressure and external forces while maintaining airtightness to prevent material leakage, ensure that there is no material leakage during operation of the system, and meet the closed operation requirements.

[0024] The feed port 101 is arranged in the middle of the barrel module 1 to facilitate feeding. A filter screen 102 is arranged below the feed port 101. The key to selecting the filter screen 102 lies in its pore size and material. It is usually made of corrosion-resistant materials such as stainless steel, and micron-level holes are formed through precise laser cutting or etching processes. The filter screen 102 should be surface treated such as electrolytic polishing to improve its corrosion resistance and reduce material adhesion. The filter screen 102 is responsible for separating solid particles and liquids in the material. Its working principle is based on physical filtration, that is, the small size of the mesh is used to prevent solid particles from passing through, while allowing liquid to flow smoothly.

[0025] A squeezing piston 103 is provided on one side of the filter screen 102. The squeezing piston 103 is usually made of wear-resistant and high-strength materials such as hardened stainless steel or ceramics. The squeezing piston 103 pushes the solid matter accumulated on the filter screen 102 to the slag discharge valve 104 through physical pressure, and promotes the liquid to pass through the filter screen 102. Its movement is driven by the cylinder 105 and is precisely controlled by the pneumatic control system to force more liquid to pass through the filter screen 102 and improve the filtration efficiency. A slag discharge valve 104 is provided on one side of the squeezing piston 103. The slag discharge valve 104 is also made of corrosion-resistant materials such as stainless steel. It includes a pneumatic or electric driven mechanism for controlling the opening and closing of the slag discharge valve 104 to discharge the filter residue. The slag discharge valve 104 opens when the squeezing piston 103 pushes the solid matter to the valve port, thereby releasing the solid matter. When closed, the system is kept sealed to prevent material leakage.

[0026] A cylinder flange 4 is provided on the other side of the filter screen 102. The cylinder flange 4 is usually made of the same material as the cylinder, such as stainless steel, to ensure consistency and corrosion resistance.

The cylinder flange 4 is a key component for connecting the cylinder module 1 with pipelines, other equipment or closures. The system's sealing and structural integrity are ensured by bolting. A sealing assembly 3 is provided on one side of the cylinder flange 4. The sealing assembly 3 is usually composed of a variety of materials and components to achieve efficient sealing of the system. The reinforcing plate 301, the pressure cover 302 and the support rod 303 are all manufactured through precision machining and assembly processes. These components may be made of stainless steel or corrosion-resistant alloy materials. The material is to be squeezed and unclamped by the cylinder 105. To ensure durability and reliability in harsh environments, a cylinder 105 is arranged on one side of the sealing component 3. The cylinder 105 is responsible for driving the extrusion piston 103 to reciprocate. Its operation is based on the pneumatic principle. The compressed air generates a linear motion, thereby realizing the extrusion and release of the material. The cylinder 105 is located at the right end of the barrel module 1. A cylinder control module 2 is arranged on one side of the cylinder 105. The cylinder control module 2 is composed of precision mechanical parts and electronic control elements. The mechanical parts are processed by high-precision CNC machine tools to ensure precise matching between parts. It is responsible for receiving signals from the detection sensor 203, and instructing the solenoid valve 202 to adjust the compressed air flow in the air circuit 201 according to these signals, thereby controlling the action of the cylinder 105.

It will also undergo precise machining and necessary heat treatment processes to ensure that it has sufficient strength and durability. The set screw 7 is used to tightly fix adjacent components together, thereby ensuring the airtightness and stability of the entire system, and maintaining the integrity and safety of the structure even under high-pressure environments. A gasket 8 is arranged on one side of the set screw 7. The gasket 8 is usually made of a material with good pressure resistance and elasticity such as rubber or Teflon.

[0028] As a preferred embodiment, a flange 9 is provided on the outside of the filter screen 102. The flange 9 is usually made of the same material as the barrel module 1, such as stainless steel, and is processed by CNC machine tools to ensure the accuracy of the connecting holes and the flatness of the surface. For special applications facing corrosive environments, the surface of the flange 9 may also be specially treated or coated. The flange 9 is arranged at the left end of the barrel module 1 and connected to the slag discharge valve 104. A discharge port 10 is provided on one side of the flange 9. The discharge port 10 serves as a channel for discharging materials from the system. The design of the discharge port 10 should ensure smooth material flow while avoiding To avoid blockage and leakage, ensure that the material can be discharged from the system smoothly, and improve the discharge efficiency, one side of the flange 9 is connected to the cylinder flange 4, and a stuffing chamber 11 is arranged inside the cylinder flange 4. The stuffing chamber 11 is usually made of corrosion-resistant materials, such as stainless steel or special alloys. Its processing includes precise cutting, welding and machining to ensure that the cavity can withstand the pressure inside the system and remain sealed. The stuffing chamber 11 is used to accommodate the stuffing 14, and the gap between the cylinder 105 and the cylinder module 1 is closed by the compression of the stuffing 14, thereby ensuring the sealing and pressure stability of the system.

[0029] As a preferred embodiment, the sealing assembly 3 includes a reinforcing plate 301, a gland 302 and a support rod 303. The reinforcing plate 301 is generally made of high-strength materials such as stainless steel or alloy steel and is processed by a precision CNC machine tool. The surface treatment may include plating or heat treatment to improve wear resistance and corrosion resistance. The reinforcing plate 301 is used to increase the overall strength of the sealing assembly 3, especially when working under high pressure or extreme conditions, it can effectively resist deformation and stress concentration. A gland 302 is provided on one side of the reinforcing plate 301. The gland 302 is usually made of the same material as the cylinder module 1, such as stainless steel, and is processed by a high-precision CNC machine tool. The inner part of the gland 302 may be polished to ensure a good sealing effect. The gland 302 is tightly matched with the cylinder 105 and fixed in place by the support rod 303 to ensure that the sealing state is always maintained during operation. A support rod 303 is provided on one side of the gland 302. The support rod 303 is generally made of high-strength materials such as hardened stainless steel or alloy steel, and is manufactured through precision machining and heat treatment processes. The surface may be specially treated to improve wear resistance and fatigue resistance. The support rod 303 is an important component connecting the reinforcing plate 301 and the gland 302. It is fixed in a specified position by screws 12 to ensure that the entire sealing assembly 303 is in a sealed state. In order to improve the stability and sealing performance, a screw 12 is arranged on one side of the support rod 303. The screw 12 is generally made of high-strength steel or stainless steel and is produced through a standard machining process. The screw 12 is used to fasten the packing chamber 11 or other mechanical parts to ensure that they will not loosen due to vibration or pressure changes during use. The support rod 303 is connected to the cylinder 105 through the screw 12. A limit screw 13 is arranged at the center of one side of the gland 302. Two groups of limit screws 13 are arranged, and the two groups of limit screws 13 are evenly arranged along the vertical direction of the gland 302. The limit screw 13 is usually made of a strong material, such as hardened stainless steel, and is processed by a CNC machine tool. The processing obtains precise dimensions and threads. The limit screw 13 is used to limit the travel range of the cylinder 105 to ensure that it works within a safe and effective distance, thereby protecting the cylinder 105 from damage. One side of the limit screw 13 is connected to the packing chamber 11. A packing 14 is arranged inside the packing chamber 11. The packing 14 is usually made of a material with good elasticity and wear resistance, such as Teflon, rubber or flexible graphite. These materials can withstand temperature changes and maintain good sealing performance. The packing 14 is used to fill the tiny gap between the cylinder 105 and the barrel module 1, and achieves a sealing effect through its elasticity and compressibility to prevent leakage of the internal medium.

[0030] As a preferred embodiment, a speed regulating valve 15 is provided on one side of the cylinder 105. The speed regulating valve 15 is usually made of high-quality metal or alloy materials. The internal parts are precision-machined to achieve accurate control. The surface may be rust-proofed or plated to improve durability and appearance. The speed regulating valve 15 is used to control the flow rate of the gas in the system. The flow rate is changed by adjusting the degree of opening and closing of the speed regulating valve 15, thereby controlling the movement speed of the cylinder 105. One side of the speed regulating valve 15 is connected to the cylinder control module 2. The cylinder control module 2 includes an air circuit 201, an electromagnetic valve 202 and a detection sensor 203. The air circuit 201 is usually made of high-quality The air circuit 201 is made of metal pipes (such as stainless steel) or high-performance polymer materials. The pipes need to go through strict cutting, bending and welding processes to ensure the sealing and pressure resistance of the pipelines. The joints and connectors are made through precision casting and machining to ensure accurate matching with the air pipes. The air circuit 201 is used as a channel for transmitting compressed air, transmitting the compressed air from the air source to the cylinder 105. By adjusting the air flow in the air circuit 201, the speed and strength of the cylinder 105 can be controlled. A solenoid valve 202 is provided on one side of the air circuit 201. The solenoid valve 202 is mainly composed of a solenoid coil, a valve core and a valve body. These components are made through precision casting and machining.

The valve core and valve body are made of wear-resistant and corrosion-resistant materials and processed by CNC machine tools to ensure sealing and long life. The electromagnetic valve 202 controls the movement of the valve core through the magnetic force generated by the electromagnetic coil, thereby opening or closing the airflow in the air path 201. The electronic control system controls the power-on state of the electromagnetic coil through a voltage signal to achieve rapid on-off control of the airflow. A detection sensor 203 is provided on the other side of the air path 201.

[0031] As a preferred embodiment, the feed port 101 is arranged in the middle of the barrel module 1, and the material enters the filter screen 102 from the feed port 101. Furthermore, the feed port 101 is located in the middle of the barrel module 1. After the material enters from the feed port 101, it can be evenly distributed on the filter screen 102, thereby improving the filtration efficiency and uniformity. The reasonable feed position design enables the system to maintain efficient separation when processing large-flow materials, thereby improving the overall processing capacity. At the same time, the material can be quickly dispersed after entering the barrel module 1, avoiding pressure fluctuations and equipment damage caused by concentrated feeding. Since the material is evenly distributed, each area of ​​the filter screen 102 can be fully utilized, thereby improving the filtration efficiency.

[0032] As a preferred embodiment, the stuffing chamber 11 and the support rod 303 are combined with the cylinder 105 by means of screws 12, so that the reciprocating mechanism of the cylinder 105 is kept sealed by the stuffing 14 when it is displaced under the drive of the cylinder control module 2. Furthermore, the stuffing 14 is placed in the stuffing chamber 11. When the cylinder 105 reciprocates, the stuffing 14 can fit tightly between the cylinder wall and the piston rod to prevent gas or liquid leakage. The support rod 303 provides additional support to ensure that the stuffing 14 will not deform or fail under high pressure or high-speed movement. The stuffing chamber 11 and the support rod 303 are fixed to the cylinder 105 by screws 12 to ensure the stability and reliability of the entire sealing system. This design enables the stuffing 14 to adapt to the reciprocating motion of the cylinder 105, provide an efficient sealing effect, and prevent medium leakage. At the same time, the combined design of the stuffing 14 and the support rod 303 makes maintenance and replacement more convenient, and the operation can be performed by simply loosening the screws 12.

[0033] As a preferred embodiment, the intelligent recycling process includes the following steps: Step 1: The extrusion piston 103 is displaced to the rightmost end of the barrel module 1 through the cylinder 105, so that the material can smoothly enter the interior of the flange 9 through the feed port 101, wherein a signal is sent through the cylinder control module 2 to drive the cylinder 105 to drive the extrusion piston 103 to move to the rightmost end of the barrel module 1, and the material enters the barrel module 1 from the feed port 101, passes through the filter screen 102, and finally reaches the interior of the flange 9, ensuring that the material smoothly enters the system to avoid blockage and retention; Step 2: The movement of the cylinder 105 drives the extrusion piston 103 to move left and right, thereby extruding the material in the flange 9, allowing the impurities to enter the slag discharge valve 104 under the push of the extrusion piston 103, and the liquid enters the discharge port 10 through the filter screen 102, wherein the cylinder 105 drives the extrusion piston 103 to reciprocate left and right in the barrel module 1, and the extrusion piston 103 strongly squeezes the material in the flange 9, pushing the solid impurities into the slag discharge valve 104, realizing the effective separation of the solid-liquid mixture, and improving the separation efficiency and quality; Step three: The material after dry-wet separation is discharged from the device through the slag discharge valve 104, and the extrusion piston 103 is returned to the rightmost end of the cylinder module 1 through the pneumatic control of the air circuit 201 and the solenoid valve 202. Further, the slag discharge valve 104 is opened, and the material after dry-wet separation is discharged from the device. The air circuit 201 and the solenoid valve 202 control the cylinder 105 to drive the extrusion piston 103 back to the initial position, ensuring that the system quickly returns to its initial state after completing a working cycle and prepares for the next cycle of work.

[0034] The working process of the present invention is as follows: first, the material enters the barrel module 1 from the feed port 101, passes through the filter screen 102, the filter screen 102 intercepts solid impurities, and allows the liquid to pass into the discharge port 10, the cylinder 105 pushes the extrusion piston 103 to move to the left, squeezes the material in the flange 9, and pushes the impurities into the slag discharge valve 104, and the liquid continues to be discharged through the filter screen 102. The system separates the solid impurities and liquid in the solid-liquid mixture by physical interception. The filter screen 102 is used as the main interception element, and its pore size is used to intercept solid particles, while the liquid smoothly passes through the filter screen 102 into the discharge port 10, the slag discharge valve 104 is opened, and the material after dry and wet separation is discharged from the device, and the extrusion piston 103 returns to the barrel module. At the rightmost end of block 1, the sealing component 3 maintains the sealing of the reciprocating mechanism of the cylinder 105 during displacement. The combination of the stuffing 14, the stuffing cavity 11 and the support rod 303 ensures the sealing effect of the cylinder 105. At the same time, the speed regulating valve 15 adjusts the air flow speed of the cylinder control module 2. The solenoid valve 202 controls the air flow according to the signal of the sensor 203 to achieve precise control of the movement of the cylinder 105. After receiving the signal through the cylinder control module 2, the cylinder 105 reciprocates and pushes the extrusion piston 103 to move left and right. The movement of the extrusion piston 103 squeezes the material in the flange 9, and the impurities are pushed into the slag discharge valve 104 to discharge the system, while the liquid continues to be discharged through the filter. The above is the working principle of this solid-liquid separation intelligent recovery system.
