Description

Technical Field

[0001] This invention relates to the field of reaction vessel technology, specifically to a coating-processed silent reaction vessel. Background Technology

[0002] In the field of modern architecture, in order to ensure the service life and style of buildings, it is necessary to apply paint to building materials and building surfaces. In the industrial field, paint is also used to decorate and protect workpieces. The production process of paint requires the use of reaction kettles as production equipment.

[0003] Traditional coating reaction kettles mix materials by adding various auxiliary agents and reactants in a measured amount, and use a motor to drive a stirring rod to accelerate the reaction. After the reaction is complete, filtration and dilution are required. Therefore, users need to use multiple devices to perform different stages of the operation. During the stirring reaction, traditional reaction kettles do not have a mechanism to crush and filter the precipitates produced by the reaction, which can lead to incomplete material reaction and increase the user's workload. To address this, we have proposed a silent reaction kettle for coating processing. Summary of the Invention

[0007] Preferably, the bottom of the mounting shell is provided with a square groove, and the inner wall of the square groove is fixedly assembled with the outer wall of the filter screen. Both outer walls of the cleaning plate are provided with sliding holes, and the inner wall of the sliding hole is slidably connected to the outer edge of the sliding rod.

[0008] Preferably, the outer edges of roller one, roller two, and roller are all rotatably connected with steel wire ropes, the outer wall of the knob is fixedly fitted with a transmission rod, the bottom of the water collection tank is fixedly fitted with a drain pipe, the outer wall of the drain pipe is provided with a valve, and the knob is fixedly connected to the valve through the transmission rod.

[0014] Preferably, the inner wall of the filter element is divided into several spaces by several solenoid valves, and the several spaces are in an isolated state when the solenoid valves are closed.

[0015] The present invention has the following beneficial effects:

[0016] First, this invention, through its structure consisting of a main body, sealing cover, motor, auxiliary gear, worm gear, rotating shaft, and solenoid valve, utilizes the cooperation of the auxiliary gear and main gear to drive the worm gear and rotating shaft to rotate during the operation of the reactor. This allows the worm gear and rotating shaft to crush the precipitate during rotation. Simultaneously, a filter screen and filter element are used to filter the reaction product and fine precipitates, thus enabling the reactor to simultaneously perform filtering and crushing functions, reducing the user's workload.

[0017] Secondly, through the design of the air pump, main air pipe, and sealing cover structure, the present invention achieves this by having the main gear driven by the motor rotate and engage with the auxiliary gear. During this process, the temperature inside the sealing cover rises due to changes in the internal voltage of the motor. As a result, the air inside the sealing cover is discharged into the main body through the one-way valve and the main air pipe due to the thermal expansion and contraction effect. When the motor is operating continuously, the surface of the coating reaction liquid inside the main body is subjected to pressure due to changes in the pressure above the liquid surface, which increases the speed at which the reaction liquid passes through the filter screen and filter element, thereby improving the solid-liquid separation effect of the reaction vessel.

[0018] Third, through the design of the knob, mounting shell, long groove, spring, and filter screen, this invention allows the user to directly inject water into the inner wall of the reactor body through the injection shell after the reaction is completed, thereby cleaning the interior of the reactor body. After cleaning, the wastewater can be discharged through the water collection tank. During this process, the wastewater will be discharged and filtered through the water collection tank and the filter screen, respectively, facilitating the user's recycling of the cleaning water. When the valve is open during cleaning, the steel wire rope will continuously pull the cleaning plate to keep it on the inner wall of the mounting shell near the limit tube. After the valve is closed, the cleaning plate will automatically clean the sediment adhering to the filter screen and the inner wall of the mounting shell, thereby improving the user's cleaning efficiency of the reactor body.

[0028] 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.

[0029] Please see Figure 1-8 A silent reaction vessel for coating processing includes a body 1. A sealing groove 9 is formed on the top of the body 1. A sealing cover 2 is fixedly fitted onto the inner wall of the sealing groove 9. A sealing pipe 6 extends through the top of the sealing cover 2 to the inner wall of the sealing cover 2. A material injection shell 4 is fixedly fitted at the top of the sealing pipe 6. A solenoid valve 28 is installed at the connection between the material injection shell 4 and the sealing pipe 6. A through hole 10 is also formed on the top of the body 1. A gas supply pipe 27 is fixedly fitted onto the inner wall of the through hole 10. A main gas pipe 5 extends through the outer wall of the sealing pipe 6 to the inner wall of the gas supply pipe 27. A [missing information - likely a device or component] is fixedly fitted at the end of the main gas pipe 5 furthest from the gas supply pipe 27. A one-way valve 26 is provided. An air pump 3 is fixedly mounted on the outer wall of the sealing cover 2. A mounting shell 7 is fixedly mounted on the bottom of the main body 1. A knob 12 is rotatably connected to the outer wall of the mounting shell 7. A movable groove 13 is opened on the outer wall of the mounting shell 7. Long grooves 31 are opened on both inner walls of the mounting shell 7. A slide rod 32 is fixedly mounted on the inner wall of the long groove 31. A spring 33 and a cleaning plate 34 are respectively provided on the outer wall of the slide rod 32. A filter screen 35 is provided at the bottom of the mounting shell 7. Roller shaft 14 and roller shaft 2 15 are rotatably connected to the inner wall of the movable groove 13. A limit tube 16 is fixedly provided on the outer wall of the sealing cover 2. A roller 17 is rotatably connected to one end of the limiting tube 16 located outside the sealing cover 2. Vacuum groove 1 29 and vacuum groove 2 30 are respectively opened in the middle of the body 1. A water collection groove 11 is fixedly installed on the inner wall of vacuum groove 1 29. A motor 18 is fixedly installed on the inner wall of the sealing cover 2. A main gear 20 is fixedly sleeved on the output shaft of the motor 18. A secondary gear 19 meshes with the outer edge of the main gear 20. A rotating shaft 23 and a worm gear 25 are fixedly installed at the bottom of the secondary gear 19 and the main gear 20, respectively. A filter element 21 is fixedly sleeved in the middle of the rotating shaft 23. A solenoid valve 24 is fixedly sleeved on the inner wall of the filter element 21. The inner wall of the filter element 21 is fixedly equipped with a discharge pipe 8, and the outer wall of the rotating shaft 23 is provided with a filter screen 22. Through the structure of the discharge pipe 8, after the filter element 21 filters the reaction product and the precipitate, the reaction product can be directly discharged into the discharge pipe 8 through the solenoid valve 24. As the internal pressure of the body 1 continuously increases, and the pressure continuously increases when the solenoid valve 24 is open and closed, the reaction product can only be discharged through the discharge pipe 8, which makes it easier for users to distinguish between the sewage discharge point and the material discharge point, and reduces the possibility of misoperation.

[0030] The diameter of the gas supply pipe 27 is 20cm. The gas inside the sealing cover 2 flows in one direction through the main gas pipe 5 and the one-way valve 26. The output port of the vacuum pump 3 is fixedly connected to a cooling circulation pipe, and the end of the cooling circulation pipe penetrates the outer wall of the sealing cover 2 to the inner wall of the sealing cover 2. When the motor 18 is working, the hot air can be discharged through the main gas pipe 5 and completely enter the body 1. The hot air is restricted by the closure of the solenoid valve 28 and cannot leak from the injection shell 4. It can only enter the body 1 through the enveloping effect of the gas supply pipe 27, thereby achieving the effect of continuously pressurizing the liquid surface during the operation of the motor 18.

[0031] The bottom of the mounting shell 7 has a square groove, and the inner wall of the square groove is fixedly assembled with the outer wall of the filter screen 35. The outer walls on both sides of the cleaning plate 34 have sliding holes, and the inner wall of the sliding holes is slidably connected to the outer edge of the slide rod 32. The square groove makes it easy for the user to install the filter screen 35, improving the efficiency of the user to assemble the reactor. The sliding holes allow the cleaning plate 34 to move along the outer edge of the slide rod 32 when the user rotates the knob 12 in one direction, achieving the effect of self-cleaning and the functionality of the equipment, thus improving the user's cleaning efficiency of the reactor.

[0032] Among them, the outer edges of roller 14, roller 15, and roller 17 are all connected by steel wire ropes. The outer wall of knob 12 is fixedly mounted with a transmission rod. The bottom of water collection tank 11 is fixedly mounted with a drain pipe. The outer wall of the drain pipe is equipped with a valve. Knob 12 is fixedly connected to the valve through the transmission rod. One end of the steel wire rope is wrapped around the connection between knob 12 and mounting shell 7. The other end of the steel wire rope is fixedly mounted to the outer wall of cleaning plate 34. After the steel wire rope is tightened, the change in length can apply a pulling force to cleaning plate 34, so that cleaning plate 34 slides along the top of filter screen 35 towards limit tube 16, so that cleaning plate 34 has sufficient kinetic energy when the user opens the valve.

[0033] The outer wall of the cleaning plate 34 is attached to the inner wall of the mounting shell 7. When the valve is sealed, the cleaning plate 34 slides along the inner wall of the mounting shell 7 and the top of the filter screen 35. By utilizing the sliding of the cleaning plate 34 during the user's valve closing process and the connection between the mounting shell 7, the cleaning plate 34 and the filter screen 35, the cleaning plate 34 can clean the filter screen 35 and the mounting shell 7 when it moves, thereby improving the user's maintenance efficiency of the reactor.

[0034] The system includes several solenoid valves 24, which are evenly distributed along the inner wall of the filter element 21. During the material injection process, the user can use the solenoid valves 24 to ensure that the material remains in the body 1, thereby allowing for thorough mixing and reaction. After the mixing process is completed, the user can also open all the solenoid valves 24 to ensure that the pressure inside the filter element 21 is balanced with that inside the body 1, reducing the pressure on the filter element 21 and the rotating shaft 23, thus reducing the probability of damage to the filter element 21 and the rotating shaft 23 and extending the service life of the equipment.

[0035] The outer wall of the rotating shaft 23 is provided with an installation groove, and the outer wall of the filter screen 22 is fixedly assembled with the inner wall of the installation groove. The filter screen 22 is staggered with the solenoid valve 24 along the outer wall of the rotating shaft 23. The filter screen 22 can isolate the precipitate generated during the reaction process, allowing the reaction product to pass through the filter screen 22, while the precipitate can only remain in the main body 1, ensuring the filtration effect of the equipment on both. After filtration, the position and state of the precipitate can further improve the cleaning efficiency of the reactor for the user.

[0036] The bottom of the injection shell 4 is fixedly equipped with a guide pipe, and the bottom of the guide pipe is tightly fitted with the top of the air supply pipe 27. The outer wall of the spring 33 overlaps with the outer wall of the cleaning plate 34. The guide pipe can discharge all the material in the injection shell 4 into the main body 1, so that the device can perform various operations on the material. After the wire rope applies tension to the cleaning plate 34, the spring 33 can push the cleaning plate 34 to automatically reset when the wire rope is extended, thereby achieving the effect of integrating sewage discharge, wastewater recycling and automatic cleaning. This not only improves the user's work efficiency, but also improves the utilization rate of water resources.

[0037] The bottom ends of the rotating shaft 23 and the worm gear 25 are rotatably connected to the bottom inner wall of the body 1. The cleaning plate 34 is made of galvanized metal. Galvanized metal has the characteristics of wear resistance and hardness, which can reduce the wear of the cleaning plate 34 during frequent movement, thereby extending the service life of the cleaning plate 34.

[0038] The inner wall of filter element 21 is divided into several spaces by a number of solenoid valves 24. When the solenoid valves 24 are closed, the spaces are isolated. The internal space distribution of filter element 21 is separated by solenoid valves 24 after the initial injection of material. This ensures that the material cannot be discharged through the discharge pipe 8 when filter element 21 is in a closed state, thus ensuring the stirring effect of the reactor on the material. After the stirring operation is completed, when it is necessary to discharge the reaction product, the user can open the solenoid valves 24 one by one. This ensures that when the liquid level drops due to the discharge of the reaction product, the air pressure will not be reduced through the gap between the two solenoid valves 24, thus maintaining the stability of the air pressure and the uniformity of the reaction product passing through filter element 21.

[0039] When using this invention, after assembling the reactor, the user turns knob 12 to close the valve. At this time, the steel wire rope will continuously pull the cleaning plate 34 to the inner wall of the mounting shell 7 near the limit tube 16, ensuring that the material will not leak after injection. After obtaining a certain amount of material, the injection operation is carried out through the injection shell 4. After the solenoid valve 28 is opened, the material will be injected into the main body 1 through the guide pipe. Then, the user can use motor 18 to stir and crush the precipitates generated during the reaction, thereby improving the reaction effect between materials.

[0040] During the mixing and crushing process, the air inside the sealing cover 2 will be heated due to the operation of the motor 18. At this time, the hot air will squeeze the one-way valve 26, causing the one-way valve 26 to open. The hot air will be discharged into the main body 1 through the main air pipe 5, thereby increasing the pressure inside the main body 1. At the same time, the air pressure inside the sealing cover 2 will decrease, and the air pump 3 will start to operate. While ensuring the stability of the pressure inside the sealing cover 2, the outside air delivered by the air pump 3 can also be used to cool the motor 18.

[0041] After the stirring operation is completed, the user can open the solenoid valve 24 located at the end of the rotating shaft 23, allowing the reaction product to pass through the filter element 21 and filter screen 22 for filtration. The internal pressure will cause the liquid surface to be squeezed, allowing the reaction product to pass through the filter element 21 quickly, improving the filtration efficiency. Subsequently, the reaction product is discharged through the discharge pipe 8. The user collects the reaction product. During the discharge process, the liquid level drops. At this time, the user opens the other solenoid valves 24 one by one, so that the air pressure inside the rotating shaft 23 and filter element 21 is always maintained in a state of equilibrium with the internal pressure of the main body 1. After the discharge operation is completed, the user can start the cleaning and maintenance operation. First, close all the solenoid valves 24, and then inject water into the interior of the main body 1 through the filling shell 4. After the water injection is completed, the user can use the electric... The machine 18 stirs again to make the cleaning water tumble, ensuring that the adhered sediment is separated from the adhered state by the centrifugal force and the tumbling cleaning water. During this process, hot air is pressurized using the same working principle as above. After stirring, the user can turn the knob 12 to open the valve. At this time, the filter screen 35 will filter the discharged sewage. The user can recycle the filtered cleaning water. The sediment is separated from the cleaning water by the barrier effect of the filter screen 35. After the sewage is discharged, the user needs to close the valve again. During this process, the wire rope is released, causing the spring 33 to push the cleaning plate 34 to clean the top of the filter screen 35 and the inner wall of the mounting shell 7 respectively. The user can then recycle the cleaned sediment.
