Technical Field
[0001] This utility model relates to the field of coating preparation equipment technology, and in particular to a multi-stage stirred reactor for preparing Toledo crystal colored stone coating. Background Technology
[0002] With the development of the building decoration industry, the demand for and quality requirements of coatings are constantly increasing. Toledo Crystal Stone Coating, as a coating with unique decorative effects, is favored by the market. It can simulate the appearance of natural stone, has rich colors and textures, and is widely used in the decoration of building facades and other fields.
[0003] In existing technology, a multi-stage stirred reactor for preparing Toledo crystalline stone coatings may not adequately mix materials near the inner wall of the reactor due to limitations in the rotation direction and position of the stirring blades. This results in uneven distribution of components in the coating, affecting color consistency. Since the color effect of crystalline stone coatings depends on the uniform dispersion of pigments, uneven mixing can lead to areas that are too dark or too light, reducing product quality. Therefore, we propose a multi-stage stirred reactor for preparing Toledo crystalline stone coatings to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a multi-stage stirred reactor for preparing Toledo crystal stone coatings, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A multi-stage stirred reactor for preparing Toledo crystal stone coating includes: a reactor body, a top cover movably connected to the top of the reactor body, a frame fixedly installed on the top of the top cover, a rotating shaft, a stirring shaft, and a rotating rod rotatably installed inside the frame, two sets of worm gears fixedly installed on the outer side of the rotating rod, worm wheels fixedly installed on the outer side of both the rotating shaft and the stirring shaft, a sleeve rotatably installed inside the top cover and the frame, a driven gear and a driving gear fixedly installed on the outer side of the sleeve and the rotating shaft respectively, four sets of connecting rods fixedly installed on the outer side of the sleeve, a scraper fixedly installed at one end of each of the four sets of connecting rods, multiple sets of stirring blades fixedly installed on one side of each of the four sets of scrapers and the outer side of the stirring shaft, a feed inlet connected to the top of the top cover, a discharge valve connected to the bottom of the reactor body, a heating wire installed inside the reactor body, an installation frame fixedly installed on the outer side of the reactor body, and four sets of support legs fixedly installed at the bottom of the installation frame.
[0007] Preferably, the reactor body has two sets of insert rods, two sets of limiting plates, and two sets of limiting rods slidably installed inside. The two sets of insert rods are movably inserted into the outside of the top cover. One end of the insert rod and the limiting rod on the same side is fixedly installed with a connecting seat. A pull ring is fixedly installed on one side of each of the two sets of connecting seats. A return spring is sleeved on the outside of each of the two sets of limiting rods.
[0008] Preferably, the two sets of worm gears mesh with the corresponding worms, the driving gear meshes with the driven gear, the two sets of worm gears, the two sets of worms, the driving gear and the driven gear are installed in the frame, and the sleeve is rotatably installed on the outside of the stirring shaft.
[0009] Preferably, a motor is fixedly installed on one side of the frame, and one end of the rotating rod is fixedly installed on the output end of the motor.
[0010] Preferably, the top of the reactor body is provided with a fixing groove, the top cover is movably inserted into the fixing groove, and the outer side of the top cover is provided with two sets of slots, and the two sets of insert rods are movably inserted into the corresponding slots.
[0011] Preferably, the reactor body has two sets of limiting grooves inside, the two sets of limiting plates are slidably installed in the corresponding limiting grooves, and the two ends of the two sets of reset springs are respectively fixedly installed on one side of the corresponding limiting plate and one side of the corresponding limiting groove.
[0012] In this invention, a multi-stage stirred reactor for preparing Toledo polycrystalline stone coatings utilizes the cooperation of a pull ring, connecting seat, insert rod, limiting rod, and limiting plate. The retraction of the return spring disengages the insert rod from the slot in the top cover, and the limiting plate slides within the limiting groove, releasing the displacement restriction on the top cover. Through the elastic force of the return spring, all components can be reset without external force, and the top cover can be re-locked. No complex tools or additional auxiliary equipment are required. Compared to traditional complex reactor disassembly methods, this significantly saves time and effort and improves the efficiency of cleaning work.
[0013] This utility model features a reasonable structural design. By incorporating a feed inlet and heating wire, it ensures the stable entry of materials for preparing Toledo polycrystalline stone coatings into the reactor and facilitates heating. Through the interaction of the motor, rotating rod, and two sets of worm gears, the worm wheels mesh with each other, driving the two sets of worm wheels to rotate. The rotating shaft and stirring shaft rotate synchronously in the forward direction, which in turn drives the driving gear to rotate. The driving gear meshes with the driven gear, driving the driven gear to rotate in the reverse direction, which in turn drives the sleeve to rotate in the reverse direction. This, in turn, causes the connecting plate and scraper to scrape the inner wall of the reactor, allowing the material adhering to the inner wall to detach. The stirring shaft's outer agitator... The stirring blades on one side of the mixing blade and the scraper blade stir in opposite directions, which can fully mix the materials in the reaction vessel. After mixing, the materials are discharged through the discharge valve. This design allows the stirring blades on the outside of the stirring shaft and the stirring blades on the scraper side to stir in opposite directions. When stirring the Toledo crystalline stone coating material, the stirring flow in different directions interacts, which can break the stirring dead zone that may be generated by stirring in one direction. This scraping action can effectively remove the material adhering to the inner wall of the reaction vessel. Toledo crystalline stone coating contains sticky components, which are easy to adhere to the vessel wall during stirring. Through scraping, these adhered materials can be detached and participate in the mixing again, avoiding the waste of raw materials. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-5 A multi-stage stirred reactor for preparing Toledo polycrystalline stone coating includes: a reactor body, a top cover movably connected to the top of the reactor body, a frame fixedly installed on the top of the top cover, a rotating shaft, a stirring shaft, and a rotating rod rotatably installed inside the frame, two sets of worm gears fixedly installed on the outer side of the rotating rod, worm wheels fixedly installed on the outer side of both the rotating shaft and the stirring shaft, a sleeve rotatably installed inside the top cover and the frame, a driven gear and a driving gear fixedly installed on the outer side of the sleeve and the rotating shaft respectively, four sets of connecting rods fixedly installed on the outer side of the sleeve, a scraper fixedly installed at one end of each of the four sets of connecting rods, multiple sets of stirring blades fixedly installed on one side of each of the four sets of scrapers and the outer side of the stirring shaft, a feed inlet connected to the top of the top cover, a discharge valve connected to the bottom of the reactor body, a heating wire installed inside the reactor body, an installation frame fixedly installed on the outer side of the reactor body, and four sets of support legs fixedly installed at the bottom of the installation frame.
[0022] In this embodiment, two sets of insert rods, two sets of limiting plates, and two sets of limiting rods are slidably installed inside the reactor body. The two sets of insert rods are movably inserted into the outside of the top cover. One end of the insert rod and the limiting rod on the same side is fixedly installed with a connecting seat. A pull ring is fixedly installed on one side of each of the two sets of connecting seats. A return spring is sleeved on the outside of each of the two sets of limiting rods. No complicated tools or additional auxiliary equipment are required. Compared with the traditional complicated reactor disassembly method, this method greatly saves time and effort and improves the efficiency of cleaning work.
[0023] In this embodiment, two sets of worm gears mesh with corresponding worms, and the driving gear meshes with the driven gear. The two sets of worm gears, two sets of worms, driving gear and driven gear are installed in the frame. The sleeve is rotatably installed on the outside of the stirring shaft. The precise transmission ratio can ensure that the stirring blade and scraper rotate according to the design requirements, so as to achieve efficient stirring and scraping.
[0024] In this embodiment, a motor is fixedly installed on one side of the frame, and one end of the rotating rod is fixedly installed on the output end of the motor, thus avoiding energy loss and insufficient power caused by power dispersion.
[0025] In this embodiment, a fixing groove is provided on the top of the reactor body, and the top cover is movably inserted into the fixing groove. Two sets of slots are provided on the outer side of the top cover, and two sets of insert rods are movably inserted into the corresponding slots. This tight insertion structure can effectively prevent paint leakage and ensure the sealing of the reactor interior.
[0026] In this embodiment, the reactor body has two sets of limiting grooves inside, and two sets of limiting plates are slidably installed in the corresponding limiting grooves. The two ends of the two sets of reset springs are respectively fixedly installed on one side of the corresponding limiting plate and one side of the corresponding limiting groove, ensuring the orderliness and accuracy of the entire operation process.
[0027] In this embodiment, during use, the material for preparing Toledo Crystal Stone Coating is placed in the reactor body through the feed inlet. The heating wire is energized, and the motor is started to drive the rotating rod and two sets of worm gears to rotate. Through the meshing between the worm wheel and the worm, the two sets of worm wheels are driven to rotate. The rotating shaft and the stirring shaft rotate synchronously in the forward direction, which in turn drives the driving gear to rotate. Through the meshing between the driving gear and the driven gear, the driven gear is driven to rotate in the reverse direction, which in turn drives the sleeve to rotate in the reverse direction. This causes the connecting plate and the scraper to scrape the inner wall of the reactor, allowing the material adhering to the inner wall of the reactor to fall off. Through the stirring of the stirring blades on the outside of the stirring shaft and the stirring blades on the side of the scraper in opposite directions, the material in the reaction vessel can be fully mixed. After mixing, the material is discharged through the discharge valve.
[0028] When cleaning the stirring blades or the inner wall of the reactor, the pull ring is pulled simultaneously to move the insert rod, limit rod, and limit plate relative to each other through the corresponding connecting seat. The reset spring retracts, the insert rod disengages from the slot of the top cover, and the limit plate slides in the limit groove, thereby releasing the displacement restriction on the top cover. After cleaning, the components can be reset without external force by the elastic force of the reset spring, and the top cover can be locked again.
[0029] The above provides a detailed description of the multi-stage stirred reactor for preparing Toledo polycrystalline stone coatings provided by this utility model. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are only intended to aid in understanding the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
