Description

Technical Field

[0001] This invention belongs to the technical field of valve production equipment, and particularly relates to a valve soaking treatment tank and its usage method. Background Technology

[0002] During the production process, valves typically require soaking in an immersion treatment tank to remove impurities such as oil and grease from the valve surface, as well as to remove rust and oxide scale, thereby fully exposing the metal body of the valve and facilitating subsequent processing. Existing valve soaking treatment tanks typically consist of a soaking tank body and a valve placement platform. The valve placement platform is driven to move up and down by a lifting drive device. During valve soaking treatment, the valve is placed on the platform, and then the lifting drive device lowers the platform into the soaking tank body so that the soaking medium in the soaking tank body submerges the valve. After the soaking treatment is completed, the platform is raised, and after replacing a batch of valves, the soaking treatment operation continues. In the existing valve soaking treatment tank, the soaking medium in the main body of the tank is generally static during operation. This leads to insufficient soaking treatment of valves, and valves are prone to residual oil, grease, rust, or oxide scale after soaking, which affects the subsequent processing of valves. Therefore, it is necessary to make improvements. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned technical problems by providing a valve soaking treatment tank and its usage method, so as to effectively improve the soaking treatment effect of the valve soaking treatment tank on valves.

[0004] In view of this, the present invention provides a valve soaking treatment tank, comprising: A pool base, on which a pool body is mounted, and the pool body is filled with an immersion medium; A placement platform is provided above the main body of the pool, and the placement platform moves up and down along the axial direction of the main body of the pool via a lifting drive device. A drying mechanism is installed above the main body of the tank to dry the valves after soaking. Also includes: A dynamic flow generating mechanism is disposed within the pool body and located at the bottom of the pool body. The dynamic flow generating mechanism includes a stirring flow generating component that generates a dynamic flow of the medium by stirring the soaking medium.

[0005] In this technical solution, the dynamic flow generation mechanism forms a three-dimensional dynamic flow through the stirring flow generation component, which makes the soaking medium form a composite flow, fully covering the valve cavity, valve stem connection and other hidden parts, effectively eliminating soaking dead corners, effectively improving the removal efficiency of stubborn oil stains and rust, and effectively shortening the soaking time.

[0006] In the above technical solution, the stirring flow generating component further includes: A stirring main shaft is rotatably mounted at the bottom of the tank body and driven to rotate by a stirring motor. A stirring rod is provided at the top of the stirring main shaft. A secondary stirring shaft is provided, which is perpendicular to the main stirring shaft and distributed on both sides of the main stirring shaft. The secondary stirring shaft is connected to the main stirring shaft so as to rotate with the main stirring shaft. A secondary stirring rod is provided at the outer end of the secondary stirring shaft. The main stirring rod and the auxiliary stirring rod generate dynamic flows in the horizontal and vertical directions in the soaking medium by rotating.

[0007] Furthermore, the above technical solution also includes: A vertical jet tube is disposed at the outer end of the stirring main rod; The vertical jet pipe, as the stirring rod rotates, causes the soaking medium to be sprayed vertically upward to form a dynamic jet.

[0008] In the above technical solution, the dynamic flow generation mechanism further includes: A vibration flow generator is disposed at the bottom of the pool body; The vibration flow generator impacts the main body of the tank as the stirring shaft rotates, thereby using the vibration of the main body of the tank to generate a vibrational dynamic flow in the soaking medium.

[0009] In the above technical solution, the vibration flow generating component further includes: A concave cavity is provided at the bottom of the pool body and is formed by the inner bottom surface of the pool body being recessed downwards; An external vibrating ball is disposed in a concave cavity, a first magnet is disposed on the top of the external vibrating ball, and the interior of the external vibrating ball has a cavity; An inner vibrating ball is disposed in the cavity of an outer vibrating ball; The second magnet is disposed at the end of the stirring rod; The outer vibrating ball is suspended in the cavity via a first elastic connecting arm and is located directly below the stirring shaft. The inner vibrating ball is suspended in the cavity of the outer vibrating ball via a second elastic connecting arm.

[0010] In the above technical solution, the drying mechanism further includes: An air intake box, wherein the air intake box is annular and has an annular air intake chamber inside; An annular air pipe is installed above the pool body and the placement platform, and several air nozzles are distributed circumferentially on the annular air pipe. A turntable, which is ring-shaped, is rotatably mounted at the bottom of the air intake box, and has several air holes on the turntable that connect the air intake chamber with the external environment; A connecting airway, wherein the connecting airway has several circumferentially evenly distributed on an annular airway; An intake heating pipe is provided on one side of the top of the intake box to heat the outside air and deliver it to the intake chamber; One end of the connecting air pipe is fixedly connected to a turntable and communicates with the air inlet chamber through an air hole, while the other end is connected to and communicates with an annular air pipe. The turntable rotates with the delivery of external air through an airflow follower, and the annular air pipe rotates synchronously with the turntable.

[0011] In the above technical solution, the airflow follower further includes: Follow-up ring, the follow-up ring is disposed at the top of the air intake chamber, and a number of airflow baffles are evenly distributed on the upper surface of the follow-up ring along the circumference; The connecting rod has several rods that are evenly spaced along the circumference of the intake chamber; One end of the connecting rod is connected to the bottom surface of the follower ring, and the other end is connected to the upper surface of the turntable. The intake heating pipe delivers external air to the inlet of the intake chamber and is located on the same plane as the follower ring, and the axial direction of the intake heating pipe is tangent to the circumferential direction of the follower ring.

[0012] In the above technical solution, the intake heating pipe further includes: A heating tube section, wherein the exhaust port of the heating tube section is connected to the air inlet chamber, and an electric heating wire is provided in the heating tube section; An air intake pipe section is provided at the air inlet of the heating pipe section, and a fan is installed in the air intake pipe section.

[0013] Furthermore, the above technical solution also includes: A heat-conducting plate assembly, wherein the heat-conducting plate assembly is composed of several first heat-conducting plates and second heat-conducting plates that are alternately spaced along the axial direction of the heating pipe section; The heat-conducting sheet assembly is mounted on the electric heating wire. The edge of the first heat-conducting sheet is connected to the inner wall of the heating tube segment, and the center of the first heat-conducting sheet has a through hole for air to pass through. The edge of the second heat-conducting sheet has a gap for air to pass through between it and the inner wall of the heating tube segment.

[0014] Furthermore, in the above technical solution, the present invention also discloses a method of use applicable to the above-mentioned valve soaking treatment tank, comprising the following steps: S1 Valve placement: Control the lifting drive device to raise the placement platform and remove it from the soaking medium in the main body of the pool. Then place the valve to be soaked on the placement platform. S2 Immersion: After the valve is placed, control the lifting drive device to lower the placement platform into the main body of the pool, and ensure that the immersion medium completely submerges the valve; S3 generates dynamic flow of medium and controls the operation of the stirring motor. After the stirring motor starts running, the stirring flow generator produces dynamic flow in the horizontal direction and dynamic flow in the vertical direction in the immersion medium. At the same time, as the stirring sub-shaft rotates, the vibrating flow generator operates under the action of magnetic force and generates vibrating dynamic flow. S4 Drying: After the valve is soaked, the lifting drive device is controlled to raise the placement platform again. After the placement platform is completely removed from the soaking medium, the drying mechanism is started. The annular air pipe blows heated air from several nozzles to the valve. At the same time, the annular air pipe rotates synchronously during the blowing process.

[0015] In this technical solution, a multi-directional and multi-layered composite medium flow path is formed by a dynamic flow generation mechanism, which effectively improves the immersion treatment effect of the valve. At the same time, the drying mechanism can perform drying operations in all directions to ensure that hot air evenly covers the valve surface.

[0016] The beneficial effects of this invention are: 1. Thorough and efficient soaking: The dynamic flow generation mechanism forms a three-dimensional dynamic flow of "horizontal rotation + vertical rotation + vertical spray" through the stirring flow generation component. Combined with the vibrating dynamic flow generated by the vibrating flow generation component, the soaking medium forms a multi-directional and multi-layer composite flow, which fully covers the valve cavity, valve stem connection and other hidden parts, effectively eliminating soaking dead corners, effectively improving the removal efficiency of stubborn oil stains and rust, and significantly shortening the soaking time.

[0017] 2. Uniform and rapid drying: The drying mechanism adopts a rotary annular air pipe design, which achieves 360° all-round jetting under the drive of the airflow follower, ensuring that hot air evenly covers the valve surface; the heat-conducting fin group in the air intake heating pipe increases the heat exchange area, and the tortuous airflow path makes the air more fully heated, improves heating efficiency, shortens drying time, and avoids the problem of local overheating and oxidation.

[0018] 3. High energy efficiency: The operation of the vibrating flow generator and the rotation of the annular air pipe of the drying mechanism do not require additional driving devices, effectively utilizing existing driving energy and improving energy efficiency. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0033] This embodiment of a valve soaking treatment tank includes a tank base 1, a tank body 2, a placement platform 3, a lifting drive device 4, a drying mechanism 5, and a dynamic flow generation mechanism 6. These components work together to complete the soaking and drying operations of the valves. The specific structure is as follows: Basic support structure Pool base 1: Made of high-strength steel plate welded together, providing stable support for the entire equipment. Anti-slip pads can be installed at the bottom to enhance the stability of the equipment placement.

[0034] The main body of the tank 2 is a cylindrical barrel structure, fixedly connected to the tank base 1 via four supporting legs 7 at the bottom. Vibration damping pads 8 are installed on the supporting legs 7 to reduce the transmission of vibrations generated by the subsequent vibration flow generation mechanism. The interior of the main body 2 forms a cavity for filling with the soaking medium. The top is an open opening. The cavity volume is designed according to standard valve specifications, accommodating various valves in the DN50-DN300 range (such as gate valves, ball valves, and globe valves). The soaking medium can be an alkaline cleaning solution or a special rust remover, selected based on the valve cleaning requirements.

[0035] The placement platform 3 is a circular plate-shaped structure adapted to the cavity of the main body 2 of the pool. Its diameter is smaller than the inner diameter of the main body 2 of the pool, ensuring that there is no interference between the platform and the inner wall of the main body 2 when the platform is raised or lowered. Several drainage holes 9, with a diameter of 5-8mm, are evenly distributed on the placement platform 3 to facilitate the rapid return of the medium to the main body 2 of the pool after soaking, preventing residue. Protective railings can be welded to the edge of the platform to prevent the valve from slipping during raising and lowering.

[0036] The lifting drive device 4 includes two lifting cylinders (hydraulic or pneumatic) symmetrically distributed on both sides of the pool body 2, a support frame, and a connecting arm. The lifting cylinders are fixedly mounted on the pool base 1 via flanges. The support frame has a frame structure with a vertical guide groove on its upper part. One end of the connecting arm slides into the guide groove via a slider, and the other end is welded to the edge of the placement platform 3. The drive end of the lifting cylinder is connected to the middle of the connecting arm. Through the extension and retraction of the lifting cylinder, the connecting arm slides up and down along the guide groove, thereby achieving smooth lifting and lowering of the placement platform 3.

[0037] Dynamic flow generation mechanism 6 The dynamic flow generation mechanism 6 is located at the bottom of the pool body 2, and includes a stirring flow generator 10 and a vibration flow generator 11. The two work together to generate a multi-directional, multi-level dynamic flow of the medium. The specific structure is as follows: (1) Stirring flow generator 10 The stirring shaft 12, made of stainless steel, is rotatably mounted at the bottom center of the tank body 2 cavity via a conventional rotating bearing, with its axis coinciding with the axis of the tank body 2. The bottom end of the stirring shaft 12 penetrates the bottom of the tank body 2 and extends to the outside, connecting to the drive end of the stirring motor 13 via a coupling. A rotating sealing pair is provided at the penetration point between the stirring shaft 12 and the bottom of the tank body 2 to prevent leakage of the soaking medium. The stirring motor 13 is fixedly mounted at the bottom of the tank body 2 via a flange; a variable frequency motor is selected, and the speed can be adjusted (50-300 r / min) according to the soaking requirements.

[0038] The agitator shaft 15 mounting housing 14 is cylindrical with an internal cylindrical cavity. It has a connecting flange at the bottom and a central hole at the top for the agitator shaft 12 to pass through. The mounting housing is fixedly installed on the bottom surface of the tank body 2 cavity via the connecting flange, and is coaxially distributed with the agitator shaft 12. Symmetrical through holes 46 are provided on both sides for the agitator shaft 15 to pass through.

[0039] Two agitator shafts 15, made of stainless steel, are symmetrically distributed on both sides of the mounting housing, perpendicular to the main agitator shaft 12. The inner end of the agitator shaft 15 extends into the cavity of the mounting housing, and the outer end extends through the through hole 46 of the mounting housing into the cavity of the tank body 2. A rotary bearing is provided between the agitator shaft 15 and the through hole 46 of the mounting housing to achieve a circumferential rotation and axial fixation fit.

[0040] The transmission bevel gear set 16 includes a driving bevel gear and two driven bevel gears. The driving bevel gear is sleeved and fixed in the part of the stirring main shaft 12 located in the cavity of the mounting housing, and rotates synchronously with the stirring main shaft 12. The two driven bevel gears are respectively sleeved and fixed in the inner ends of the two stirring auxiliary shafts 15, and mesh with the driving bevel gear. When the stirring main shaft 12 rotates, the two stirring auxiliary shafts 15 are driven to rotate synchronously through the meshing transmission of the bevel gears, and the direction of rotation is perpendicular to the stirring main shaft 12.

[0041] The stirring rod 17 is made of stainless steel square tubing and is horizontally welded to the top of the stirring shaft 12. Its length is 1 / 3 to 1 / 2 of the inner diameter of the tank body 2, and its two ends are symmetrically distributed. A liquid inlet 20 is provided on the front side (one side along the direction of rotation) of the stirring rod 17.

[0042] Agitator rod 18: Also made of stainless steel square tubing, it is horizontally welded to the outer end of agitator shaft 15, with a length of 1 / 4 to 1 / 3 of the inner diameter of the tank body 2, and is distributed perpendicularly to agitator rod 17. The surface of agitator rod 18 may be uniformly welded with several turbulent protrusions to enhance the disturbance effect on the soaking medium.

[0043] Vertical jet tube 19: This is a stainless steel round tube, vertically welded to the upper surface of the outer end of the stirring main rod 17, with its bottom connected to the liquid inlet 20 on the stirring main rod 17. The top of the vertical jet tube 19 can have a slanted cut structure with a cut angle of 45°, facilitating the vertical upward spraying of the soaking medium. When the stirring main rod 17 rotates with the stirring main shaft 12, under the action of centrifugal force, the soaking medium enters the vertical jet tube 19 through the liquid inlet 20 and is sprayed vertically upward at high speed through the slanted cut, forming a dynamic jet in the vertical direction.

[0044] When the stirring flow generator 10 is working, the stirring main shaft 12 drives the stirring main rod 17 to perform a circular motion, generating a horizontal rotating fluid; the stirring secondary shaft 15 drives the stirring secondary rod 18 to perform a circular motion perpendicular to the main shaft, enhancing fluid disturbance in the vertical direction; at the same time, the vertical jet pipe 19 sprays a vertical dynamic jet, which superimposes with the horizontal fluid to form a three-dimensional dynamic flow of "horizontal rotation + vertical injection", which fully covers all parts of the valve and achieves thorough soaking.

[0045] (2) Vibration flow generator 11 Cavity 21: integrally formed with the main body of the tank 2, formed by the downward recess of the inner bottom surface of the main body of the tank 2, and can be in the form of a semi-cylindrical or hemispherical structure. There are two in total, symmetrically distributed on both sides of the mounting shell, and located directly below the two stirring shafts 15.

[0046] The outer vibrating ball 22 is made of wear-resistant rubber and has a diameter slightly smaller than the inner diameter of the cavity 21. It is suspended inside the cavity 21 by two or three first elastic connecting arms 23. The first elastic connecting arm 23 is an arc-shaped spring, with one end welded to the inner wall of the cavity 21 and the other end bonded or bolted to the outer wall of the outer vibrating ball 22. The two or three connecting arms are evenly distributed along the circumference of the outer vibrating ball 22 to ensure the stable suspension of the outer vibrating ball 22. A first magnet 24, a strong neodymium iron boron magnet, is bonded to the top of the outer vibrating ball 22 with its magnetic poles facing upwards. The interior of the outer vibrating ball 22 has a spherical cavity.

[0047] The inner vibrating ball 25 is made of hard plastic (non-magnetic material) and has a diameter of 1 / 3 to 1 / 2 of the inner diameter of the cavity of the outer vibrating ball 22. It is suspended inside the cavity of the outer vibrating ball 22 by two to four second elastic connecting arms 26. The second elastic connecting arms 26 are also arc-shaped springs, with one end bonded to the inner wall of the outer vibrating ball 22 and the other end bonded to the outer wall of the inner vibrating ball 25. The two to four connecting arms are evenly distributed along the circumference of the inner vibrating ball 25. The upper and lower sides of the inner vibrating ball 25 have integrally formed hemispherical protrusions 27 to enhance the impact effect.

[0048] The second magnet 28 is bonded and fixed to the end surface of the stirring rod 18. It is a strong neodymium iron boron magnet with the same specifications as the first magnet 24. Its magnetic poles are arranged downwards, and the magnetic poles opposite to the first magnet 24 are the same magnetic poles (both are N poles or both are S poles), forming a magnetic repulsion force.

[0049] When the vibration flow generator 11 is working, the stirring rod 18 rotates with the stirring shaft 15. When the second magnet 28 rotates to directly above the outer vibrating ball 22, it generates a strong magnetic repulsion force with the first magnet 24, pushing the outer vibrating ball 22 downward and stretching the first elastic connecting arm 23. When the stirring rod 18 rotates away, the magnetic repulsion force disappears, and the elastic restoring force of the first elastic connecting arm 23 drives the outer vibrating ball 22 to reset upward and impact the inner wall of the cavity 21, generating vibration. At the same time, during the movement of the outer vibrating ball 22, the inner vibrating ball 25 inside it impacts the inner wall of the outer vibrating ball 22 under the action of inertia, further enhancing the vibration intensity. This dual vibration mode of "outer ball impact + inner ball auxiliary impact" causes the pool body 2 to vibrate uniformly, thereby driving the soaking medium to generate a vibrating dynamic flow. The vibration frequency is synchronized with the rotation speed of the stirring shaft 15 (100-600 times / minute), which can effectively remove stubborn oil and rust from the valve surface.

[0050] Drying unit 5 Air intake box 29: Made of welded stainless steel sheet, it has a cylindrical ring structure and is fixedly installed on the main body of the pool 2. In this embodiment, the air intake box 29 is fixed by arranging a mounting bracket at the top of the support frame of the lifting drive device 4. The air intake box 29 forms a cylindrical ring-shaped air intake cavity 30 inside, and its bottom has concentrically distributed annular openings. The diameter of the annular openings is smaller than the diameter of the air intake cavity 30, so that the bottom of the air intake cavity 30 naturally forms an annular support platform.

[0051] Turntable 31: T-shaped cross-section, integrally formed from a panel and a web, both made of stainless steel. The diameter of the panel matches the inner diameter of the air intake chamber 30 and is mounted on the support platform of the air intake chamber 30; the diameter of the web matches the annular opening at the bottom of the air intake box 29 and is embedded within the annular opening. Movable sealing pairs are provided on the contact surfaces of the turntable 31 with the annular opening at the bottom of the air intake box 29 and the inner wall of the air intake chamber 30, ensuring that heated air can only flow out through the air holes 35 on the turntable 31; simultaneously, rotating bearings are provided on the contact surfaces to ensure the turntable 31 rotates flexibly. Several air holes 35 are evenly distributed circumferentially on the turntable 31.

[0052] The annular air pipe 32 is made of stainless steel round tubing and has an annular structure. It is positioned directly above the placement platform 3 and is fixedly connected to the bottom of the turntable 31 via several connecting air pipes 33. Several air nozzles 36 are evenly distributed circumferentially along the bottom of the annular air pipe 32. The air nozzles 36 have a universal adjustable structure, allowing the air outlet direction to be adjusted according to the valve height and shape. The air outlet of the air nozzles 36 is flat, enhancing the airflow coverage.

[0053] Connecting air tubes 33: There are three to six of them, made of stainless steel round tubes, and they are evenly distributed around the annular air tube 32. One end of the connecting air tube 33 is welded and fixed to the bottom of the turntable 31 and communicates with the air hole 35 on the turntable 31; the other end is welded and fixed to the top of the annular air tube 32, so as to realize the airflow connection between the air inlet chamber 30 and the annular air tube 32.

[0054] The intake heating pipe 34 includes a heating pipe section 40 and an intake pipe section 41, both made of stainless steel round tubing. One end of the heating pipe section 40 is fixed to the side wall of the intake box 29 via a flange structure or welding, communicating with the intake chamber 30; the other end is closed, and an electric heating wire 42 is installed inside. The electric heating wire 42 is a conventional nickel-chromium alloy heating wire, fixed to the center of the heating pipe section 40 via a ceramic insulator, with its control end extending to the outside of the closed end of the heating pipe section 40 for easy connection to a power supply and temperature control device. The intake pipe section 41 is welded to the lower part of the heating pipe section 40 away from the intake box 29, communicating with the interior of the heating pipe section 40. It contains a conventional fan, and its air inlet can be equipped with a high-efficiency filter element to filter dust and impurities in the air, preventing contamination of the valve surface.

[0055] The heat-conducting plate assembly 43 consists of several alternating first heat-conducting plates 44 and second heat-conducting plates 45, all made of copper and possessing excellent thermal conductivity. The heat-conducting plate assembly 43 is threaded onto the electric heating wire 42. The edges of the first heat-conducting plates 44 are welded and fixed to the inner wall of the heating tube section 40, and a circular through-hole 46 (with a diameter half the diameter of the first heat-conducting plate 44) is opened in the center. An annular gap 47 (with a width 1 / 5 the inner diameter of the heating tube section 40) is reserved between the edge of the second heat-conducting plate 45 and the inner wall of the heating tube section 40, and there is no through-hole 46 in its center. When air flows within the heating tube section 40, it passes sequentially through the through-hole 46 of the first heat-conducting plate 44 and the gap 47 of the second heat-conducting plate 45, forming a tortuous flow path, ensuring sufficient contact and heat exchange with the heat-conducting plates, and improving heating efficiency.

[0056] Airflow follower: Includes a follower ring 37 and three to six connecting rods 39. The follower ring 37 is made of stainless steel, has a ring structure, and its diameter is smaller than the diameter of the intake chamber 30. It is connected to the top of the turntable 31 via the connecting rods 39. The connecting rods 39 are stainless steel round rods, one end of which is welded and fixed to the bottom surface of the follower ring 37, and the other end is welded and fixed to the upper surface of the turntable 31. The three to six connecting rods 39 are evenly distributed circumferentially to ensure stable transmission. Several airflow baffles 38 are evenly welded circumferentially to the upper surface of the follower ring 37. The airflow baffles 38 are preferably open box-shaped structures, and their openings face the direction in which external air enters the intake chamber 30 when the intake heating pipe 34 delivers external air to the inlet of the intake chamber 30. When the air intake heating pipe 34 delivers heated air to the air intake chamber 30, the airflow impacts the airflow baffle 38, generating a driving force along the circumference of the follower ring 37, which drives the follower ring 37, connecting rod 39 and turntable 31 to rotate synchronously, thereby causing the annular air pipe 32 to rotate with the turntable 31, achieving 360° all-round drying.

[0057] auxiliary structure A liquid level sensor is installed on the inner wall of the main body 2 of the pool to monitor the liquid level of the soaking medium. When the liquid level is lower than the preset value, the control system will issue an alarm signal to remind the operator to add the medium.

[0058] The bottom of the main body 2 of the pool is provided with a drain outlet 48, and a solenoid valve 49 is provided at the drain outlet 48 to facilitate the periodic discharge of waste media and sediment.

[0059] The air inlet box 29 of the drying mechanism 5 is equipped with a temperature sensor to monitor the air temperature inside the air inlet chamber 30. The power of the electric heating wire 42 is adjusted by the temperature control device to ensure that the drying temperature is stable at 60-80℃, so as to avoid the valve surface from oxidizing due to excessive temperature.

[0060] Valve Immersion Treatment Tank Usage Method S1: Equipment Debugging and Preparation Check the connection status of each component of the equipment: ensure that the stirring main shaft 12 and stirring secondary shaft 15 rotate flexibly without jamming; the outer vibrating ball 22 of the vibrating flow generator 11 is suspended stably, and the inner vibrating ball 25 moves freely; the turntable 31 of the drying mechanism 5 rotates smoothly and is well sealed.

[0061] Inject soaking medium into the main body 2 of the pool: monitor the liquid level with a liquid level sensor to ensure that the liquid level of the medium is 10cm higher than the highest position of the valve to be treated, and close the solenoid valve 49 of the drain outlet 48.

[0062] Parameter settings: The stirring motor 13 is set to 200 r / min, the heating wire 42 is set to 70℃, the soaking time is 20 minutes, and the drying time is 15 minutes.

[0063] S2: Valve placement Start the lifting cylinder of the lifting drive device 4 to raise the placement platform 3 to the highest position, so that the platform is completely removed from the soaking medium.

[0064] Place the DN150 gate valve to be processed smoothly on the placement platform 3, ensuring that the bottom of the valve is in full contact with the platform.

[0065] S3: Immersion Operation Start the lifting cylinder to slowly lower the placement platform 3, so that the valve is fully immersed in the soaking medium. Stop when the platform reaches the lowest position.

[0066] When the stirring motor 13 is started, the stirring main shaft 12 begins to rotate, which drives the stirring auxiliary shaft 15 to rotate synchronously through the transmission bevel gear set 16. The stirring rod 17 moves in a circular motion with the stirring shaft 12, generating a rotating fluid in the horizontal direction; the vertical jet pipe 19 sprays the soaking medium vertically upward under the action of centrifugal force, forming a vertical dynamic jet, which superimposes with the horizontal fluid to form a three-dimensional dynamic flow, scouring the outer surface and inner cavity of the valve.

[0067] The stirring rod 18 rotates with the stirring shaft 15. The second magnet 28 at its end periodically passes above the outer vibrating ball 22 and generates magnetic repulsion with the first magnet 24, pushing the outer vibrating ball 22 to move up and down and hit the inner wall of the cavity 21. At the same time, the inner vibrating ball 25 hits the inner wall of the outer vibrating ball 22, generating a compound vibration, which drives the soaking medium to form a vibrating dynamic flow, peeling off stubborn oil and rust from the valve surface.

[0068] During the soaking process, the liquid level of the medium is monitored in real time by a liquid level sensor, and replenished in time if the liquid level drops; the flow status of the medium is observed through the observation window (a transparent observation window is provided on the two side walls of the main body of the pool) to ensure that the dynamic flow generation is normal.

[0069] After soaking for 20 minutes, turn off the stirring motor 13 to complete the soaking process.

[0070] S4: Drying Operation Start the lifting cylinder to slowly raise the placement platform 3, so that the valve is completely removed from the soaking medium. The platform stops after rising to the middle position (30cm away from the annular air pipe 32). The leakage hole 9 on the platform will return the medium remaining on the valve surface to the main body of the pool 2. The return time is 2 minutes.

[0071] Start the fan and electric heating wire 42 of the intake pipe section 41: Air enters the intake pipe section 41 after being filtered by a high-efficiency filter element and flows into the heating pipe section 40. The heat generated by the electric heating wire 42 is transferred to the heat-conducting fin assembly 43. The air flows along a tortuous path in the heating pipe section 40 and exchanges heat fully with the heat-conducting fins, and is heated to 70°C.

[0072] Heated air enters the intake chamber 30, impacts the airflow baffle 38 on the follower ring 37, and drives the follower ring 37, connecting rod 39 and turntable 31 to rotate synchronously (speed is 30r / min); air flows into the connecting air pipe 33 through the air hole 35 on the turntable 31, and then enters the annular air pipe 32, and is blown onto the valve surface in all directions through the jet nozzle 36 360°.

[0073] Adjust the angle of the jet nozzle 36 so that the airflow simultaneously covers the outer surface of the valve, the flange end face, and the valve stem connection, achieving uniform drying.

[0074] After drying for 15 minutes, turn off the fan and the electric heating wire 42 to complete the drying process.

[0075] S5: Finished Product Removal and Equipment Cleaning Start the lifting cylinder to raise the placement platform 3 to the highest position. The operator will then remove the treated valve and check its surface cleanliness and dryness.

[0076] Regularly clean the equipment: Open the solenoid valve 49 of the drain port 48 to discharge the waste soaking medium and sediment; remove the high-efficiency filter element of the air intake section 41 for cleaning or replacement; check the wear of each component and add lubricating oil to the rotating parts.

[0077] Working principle Principle of Three-Dimensional Dynamic Flow Generation The principle of horizontal-vertical composite flow: The stirring main shaft 12 drives the stirring main rod 17 to rotate, generating a horizontally rotating fluid using centrifugal force; the stirring auxiliary shaft 15 drives the stirring auxiliary rod 18 to rotate vertically, further agitating the horizontal fluid; simultaneously, the vertical jet pipe 19, under the action of centrifugal force, sprays the soaking medium at high speed vertically, forming a vertical jet. After the horizontal fluid and the vertical jet are superimposed, a three-dimensional flow field is formed. The fluid not only circulates horizontally but also exchanges vertically, ensuring that the soaking medium fully penetrates all concealed parts of the valve, achieving all-round cleaning.

[0078] The principle of vibration driven by magnetic repulsion: The second magnet 28 at the end of the stirring rod 18 and the first magnet 24 at the top of the outer vibrating ball 22 are of the same magnetic poles, generating periodic magnetic repulsion during rotation. This magnetic repulsion pushes the outer vibrating ball 22 downwards against the elastic force of the first elastic connecting arm 23. After the magnetic repulsion disappears, the restoring force of the elastic connecting arm causes the outer vibrating ball 22 to return to its original position and impact the cavity 21, generating vibration. Simultaneously, the inner vibrating ball 25 impacts the inner wall of the outer vibrating ball 22 under inertia, forming secondary vibration. This dual vibration is transmitted to the immersion medium, generating high-frequency vibration waves. These vibration waves can break down the adhesion of oil, rust, and valve surfaces, accelerating the cleaning process.

[0079] Rotary high-efficiency drying principle Airflow-driven rotation principle: When the intake heating pipe 34 delivers heated air to the intake chamber 30, the airflow impacts the airflow baffle 38 on the follower ring 37. Since the airflow direction is tangent to the circumference of the follower ring 37, a circumferential driving force is generated, causing the follower ring 37, connecting rod 39, and turntable 31 to rotate synchronously. The turntable 31 drives the annular air pipe 32 to rotate through the connecting air pipe 33, so that the jet nozzle 36 forms a 360° rotating jet, avoiding drying dead zones and ensuring uniform heating of all parts of the valve.

[0080] High-efficiency heat exchange principle: The heat-conducting fin group 43 inside the air inlet heating pipe 34 adopts an alternating design of first heat-conducting fin 44 and second heat-conducting fin 45. The first heat-conducting fin 44 has a closed edge and an open center, while the second heat-conducting fin 45 has an open edge and a closed center, which creates a tortuous flow path for the air within the heating pipe section 40. This path design prolongs the contact time between the air and the heat-conducting fins, increases the heat exchange area, allows the air to fully absorb heat, significantly improves heating efficiency, and reduces energy consumption.

[0081] Based on the above principles, this invention achieves high efficiency, uniformity, intelligence, and energy saving in valve soaking treatment, solves the technical defects of existing equipment, meets the needs of large-scale valve production, and has significant practical value and industrialization prospects.
