Description

Technical Field

[0001] This invention belongs to the field of valve manufacturing technology, and in particular relates to an internal residue cleaning device for valve manufacturing. Background Technology

[0002] During the manufacturing process, valves are prone to leaving internal impurities such as metal shavings, oil stains, and welding slag. If not thoroughly cleaned, these impurities will severely affect their performance and lifespan. After the valve is put into use, these residues may enter the pipeline system with the medium flow, causing scratches on the sealing surface, blockage of the flow channel, or interference with control components, leading to leaks or even system failures. Especially under high pressure, high purity, or corrosive media conditions, even tiny impurities can induce major safety accidents. In addition, residues will accelerate internal corrosion and reduce valve durability. Therefore, a rigorous internal cleaning must be performed before leaving the factory to ensure that the fluid cleanliness meets the standards, guarantee flexible valve opening and closing, reliable sealing, meet the stringent safety and stability requirements of industrial systems, and improve overall operating efficiency and equipment reliability.

[0003] When cleaning residues inside valves, ultrasonic cleaning is usually used. Although ultrasonic waves have a good cleaning effect, impurities that fall off during the cleaning process will settle to the bottom of the cleaning tank with the liquid and accumulate. If these deposits are not removed in time, they will not only increase the difficulty of subsequent cleaning, but may also adhere to the inner wall of the container, causing secondary pollution and affecting the subsequent cleaning effect.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: When cleaning the valve, liquid is injected into the cleaning tank, and the valve is placed on the drying assembly. The assembly is then pushed along the first support frame to the designated position, immersing the valve in the liquid.

Then, the one-way valve of the drain pipe opens, draining the liquid from the cleaning tank. The impurity removal assembly removes impurities from the bottom of the tank, ensuring the cleaning tank is clean and ready for the next cleaning. Attached Figure Description

[0015] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0016] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] Please see Figures 1 to 6 This invention provides an internal residue cleaning device for valve manufacturing, comprising: a base frame 1; a cleaning tank 2 mounted on the base frame 1, wherein an ultrasonic cleaning module is mounted on the cleaning tank 2; a drain pipe 3 installed at the bottom of the cleaning tank 2; a first support frame 4 mounted on the base frame 1 on one side of the cleaning tank 2; a placement and drying assembly mounted on the first support frame 4 for placing valves in the cleaning tank 2 and for drying the cleaned valves; and an impurity removal assembly installed in the cleaning tank 2.

[0018] Furthermore, the ultrasonic cleaning module includes: multiple ultrasonic generators 5 installed at the bottom of the cleaning tank 2, and an ultrasonic transducer 6 installed inside the cleaning tank 2.

[0019] The above scheme is as follows: When cleaning the valve is required, liquid is added to the cleaning tank 2, the valve is placed in the drying assembly, and then the drying assembly is slid on the first support frame 4 to a preset position, immersing the valve in the liquid of the cleaning tank 2. Through the coordinated work of the ultrasonic generator 5 and the ultrasonic transducer 6, ultrasonic waves propagate in the liquid and generate bubbles. The shock waves generated when the bubbles burst can powerfully peel off the residue from the inner wall, gaps, and blind holes of the valve. After cleaning, the drying assembly moves in the opposite direction, causing the valve to be removed from the cleaning tank 2 and dried. Subsequently, the one-way valve in the drain pipe 3 opens, and the liquid in the cleaning tank 2 is drained. At the same time, the impurity removal assembly removes the impurities accumulated at the bottom of the tank, keeping the cleaning tank 2 clean and preparing it for the next cleaning.

[0020] It should be noted that the ultrasonic cleaning module is existing technology.

[0021] Furthermore, the placement and drying assembly includes: a first slider 7 slidably connected to the first support frame 4; a first motor 8 mounted on the first support frame 4; a first reciprocating screw 9 mounted on the output end of the first motor 8; and the first slider 7 being threadedly connected to the first reciprocating screw 9.

[0022] Furthermore, a placement frame 10 is fixedly connected to one side of the first slider 7; a support frame 11 is fixedly connected to the top of the placement frame 10, and a first slide rail 12 is provided on the support frame 11.

[0023] Furthermore, an electric slider 13 is slidably connected within the first slide rail 12; an electric telescopic rod 14 is installed at the bottom of the electric slider 13; a first fixing plate 15 is fixedly connected to the extended end of the electric telescopic rod 14, and two symmetrically arranged fans 16 are installed on the first fixing plate 15.

[0024] Using the above method: When in use, place the valve to be cleaned into the placement rack 10 and arrange them neatly. Then start the first motor 8, and its output end rotates to drive the first reciprocating screw 9 to rotate. Due to the threaded connection, the rotation of the first reciprocating screw 9 pushes the first slider 7 to slide along the first support frame 4, so that the placement rack 10 moves to one side of the cleaning tank 2, immersing the valve in the liquid. Ultrasonic cleaning begins. After cleaning is completed, the first reciprocating screw 9 rotates in the reverse direction, the placement rack 10 moves in the reverse direction, and the valve is removed from the liquid. Subsequently, the electric telescopic rod 14 lowers the first fixed plate 15, the fan 16 starts and blows gas toward the valve, and at the same time the electric slider 13 moves back and forth in the first slide rail 12 to ensure that the gas is blown evenly toward the valve, completing the air drying process.

[0025] Furthermore, the impurity removal assembly includes: a second reciprocating screw 17 rotatably connected to the cleaning tank 2, and a first fixing bracket 18 threadedly connected to the second reciprocating screw 17; a second motor 19 is installed on one side of the cleaning tank 2, and one end of the second reciprocating screw 17 is fixedly connected to the output end of the second motor 19.

[0026] Furthermore, two symmetrically arranged first telescopic rods 20 are installed on both sides of the first fixed frame 18, and a connecting ring 21 is fixedly connected to the extended end of the first telescopic rod 20; a spring 22 is installed between the connecting ring 21 and the first fixed frame 18; a first rotating shaft 23 is rotatably connected inside the connecting ring 21; two symmetrically arranged cleaning rollers 24 are installed on the first rotating shaft 23, and a pulley 25 that contacts the bottom wall of the cleaning tank 2 is fixedly connected to the middle of the first rotating shaft 23.

[0027] Furthermore, a second rotating shaft 26 is rotatably connected inside the drainage pipe 3; a spiral blade 27 is installed on the second rotating shaft 26; a synchronous pulley 28 is installed at one end of both the second rotating shaft 26 and the second reciprocating screw 17, and a synchronous belt 29 is sleeved on the synchronous pulley 28.

[0028] Using the above scheme: In use, when residual impurities need to be removed from the bottom of the cleaning tank 2, the liquid in the cleaning tank 2 is discharged through the drain pipe 3. The second motor 19 starts, its output end rotates and drives the second reciprocating screw 17 to rotate, thereby pushing the first fixed frame 18 to move. During the movement of the first fixed frame 18, the first telescopic rod 20 extends under the force of the spring 22, applying force to the connecting ring 21, so that the pulley 25 is in close contact with the bottom wall of the cleaning tank 2. At the same time, the two cleaning rollers 24 are also in close contact with the bottom wall of the cleaning tank 2. The movement of the first fixed frame 18 drives the pulley 25 to roll, thereby causing the first rotating shaft to... 23 rotates synchronously, and the cleaning roller 24 rotates accordingly, stirring and agitating the residual impurities at the bottom of the cleaning tank 2, causing them to enter the drain pipe 3 along with the liquid. The rotation of the second reciprocating screw 17 also drives the synchronous wheel 28 and the synchronous belt 29, causing the second rotating shaft 26 to rotate synchronously. The forward rotation of the spiral blade 27 transports the liquid in the drain pipe 3, preventing impurities from clogging the drain pipe 3. When the second reciprocating screw 17 rotates in the reverse direction, the spiral blade 27 also reverses, and the liquid is pushed back into the cleaning tank 2 in the reverse direction. Combined with the reset movement of the cleaning roller 24, the residual impurities are agitated a second time, preventing the impurities from settling to the bottom.

[0029] Working principle of the invention: When valves need cleaning, liquid is added to the cleaning tank 2. The valves to be cleaned are placed in the placement rack 10 and arranged neatly. The first motor 8 is started, and its output rotates, driving the first reciprocating screw 9 to rotate. Due to the threaded connection, the rotation of the first reciprocating screw 9 pushes the first slider 7 to slide along the first support frame 4, moving the placement rack 10 to one side of the cleaning tank 2, immersing the valves in the liquid. Through the coordinated work of the ultrasonic generator 5 and the ultrasonic transducer 6, ultrasonic waves propagate in the liquid and generate bubbles. The shock waves generated when the bubbles burst can powerfully peel away residues from the valve's inner wall, gaps, and blind holes. After cleaning, the first reciprocating screw 9 rotates in the reverse direction, the placement rack 10 moves in the reverse direction, and the valves are removed from the liquid. Subsequently, the electric telescopic rod 14 lowers the first fixed plate 15, the fan 16 starts, and blows gas towards the valves. Simultaneously, the electric slider 13 reciprocates within the first slide rail 12, ensuring that the gas is evenly blown onto the valves, completing the drying process. Then, the one-way valve in the drain pipe 3 opens, and the liquid in the cleaning tank 2 is drained. When residual impurities need to be removed from the bottom of the cleaning tank 2... The liquid in the cleaning tank 2 is discharged through the drain pipe 3. The second motor 19 starts, and its output end rotates, driving the second reciprocating screw 17 to rotate, which in turn pushes the first fixed frame 18 to move. During the movement of the first fixed frame 18, the first telescopic rod 20 extends under the force of the spring 22, applying force to the connecting ring 21, so that the pulley 25 is pressed tightly against the bottom wall of the cleaning tank 2. At the same time, the two sweeping rollers 24 are also pressed tightly against the bottom wall of the cleaning tank 2. The movement of the first fixed frame 18 drives the pulley 25 to roll, which in turn causes the first rotating shaft 23 to rotate synchronously, and the sweeping rollers 24 follow suit. The rotation of the screw 17 agitates and stirs the residual impurities at the bottom of the cleaning tank 2, causing them to enter the drain pipe 3 along with the liquid. The rotation of the second reciprocating screw 17 also drives the synchronous pulley 28 and the synchronous belt 29, causing the second shaft 26 to rotate synchronously. The forward rotation of the spiral blades 27 transports the liquid in the drain pipe 3, preventing impurities from clogging the drain pipe 3. When the second reciprocating screw 17 rotates in the reverse direction, the spiral blades 27 also reverse, and the liquid is pushed back into the cleaning tank 2. Combined with the reset movement of the cleaning roller 24, the residual impurities are agitated a second time, preventing them from settling to the bottom.
