Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a polymer reaction vessel for acrylic resin coatings. Background Technology

[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Acrylic resin coatings are thermoplastic or thermosetting resin coatings or acrylic radiation coatings made by copolymerizing (meth)acrylates and styrene with other acrylates. In automobile manufacturing, acrylic resin coatings are widely used for body painting on production lines.

[0003] A known authorized patent with application number CN202220671999.2 discloses a reaction vessel for acrylic resin coatings. Its background art addresses the problem that "acrylic resin easily adheres to the walls, causing different batches of coatings to mix. Furthermore, during reaction vessel installation, minor adjustments and leveling are inconvenient, and during operation, only vertical blade stirring delays the completion time." The proposed solution addresses this problem by including a reaction vessel, an upper head, and a fixing component. A displacement motor is symmetrically fixed to the top outer wall of the fixing component, an observation window is fixedly connected to the top outer wall of the fixing component, and a displacement rotation shaft is fixedly connected to the drive end of the displacement motor.

[0004] However, the following problems were found in the implementation of the above technical solution: Although the provided technical solution achieved the effects of cleaning, leveling and vertical stirring of the inner wall of the reactor, it is not convenient to efficiently clean the material remaining on the inner wall of the reactor during use. The method of cleaning the inner wall of the reactor by relying solely on scrapers is ineffective and difficult to clean stubborn residual materials. This easily causes material to remain on the inner wall of the reactor and the scrapers, thereby reducing the effectiveness of the reactor and the quality and efficiency of coating production. Utility Model Content

[0005] This invention proposes a polymer reactor for acrylic resin coatings, which solves the problem in related technologies of the inconvenience of efficiently cleaning the material remaining on the inner wall of the reactor.

[0006] The technical solution of this utility model is as follows: A polymer reactor for acrylic resin coatings includes: a reactor body and a cover bolted to its top, wherein a stirring mechanism is provided in the reactor body; a rotating sleeve rotatably connected to the top of the cover, the rotating sleeve being rotated by a power mechanism provided on the cover; four housings fixedly installed on the surface of the rotating sleeve; a lead screw rotatably connected between the two sides of the inner wall of the housing, one end of the lead screw passing through the housing and rotating with the rotating sleeve through a linkage mechanism provided in the cover; a slider threadedly connected to the surface of the lead screw and slidably connected to the housing; a spray cylinder fixedly installed at the bottom of the slider, the surface of the spray cylinder being equipped with a nozzle; two electric push rods symmetrically fixedly installed on the surface of the rotating sleeve and located below the housing; and a cleaning scraper fixedly connected to the output end of the electric push rods.

[0007] Preferably, the linkage mechanism includes an annular shell fixedly installed on the inner wall of the cover, a rubber wheel one fixedly connected to one end of the screw and pressed against the top of the annular shell, a connecting block fixedly installed at one end of the bottom of the shell, and a rubber wheel two rotatably connected to the side of the connecting block one and pressed against the inner top wall of the annular shell, wherein the rubber wheel two and the rubber wheel one together clamp the annular shell.

[0008] Through the above structure, the present invention enables the first and second rubber wheels to rotate along the annular shell during the rotation of the shell. This causes the first rubber wheel to rotate the lead screw, which in turn drives the slider to move back and forth within the shell. This, in turn, drives the spray cylinder to move back and forth to diffuse and reduce the spray volume, ensuring the uniformity of the spray.

[0009] Preferably, the power mechanism includes a motor fixedly installed on one side of the top of the cover, and two meshing gears fixedly installed on the output end of the motor and the surface of the rotating sleeve, respectively.

[0010] Through the above structure, the present invention uses a motor to rotate in both directions, and under the action of two gears, drives the rotating sleeve to rotate in both directions, thereby driving the shell and the spraying cylinder to rotate, so that the cleaning agent sprayed from the spraying cylinder can be diffused and sprayed on the inner wall of the reaction vessel.

[0011] Preferably, two liquid inlet pipes are symmetrically installed through the top of the cap, and the four spray cylinders are connected to the two liquid inlet pipes in pairs via branch telescopic hoses.

[0012] This utility model, through the above structure and the provision of an inlet pipe, facilitates the input of liquid into the spray nozzle.

[0013] Preferably, the stirring mechanism includes a stirring rod rotatably connected to a rotating sleeve via a bearing, multiple stirring blades fixedly installed on the surface of the stirring rod, a fixing block fixedly installed on the cover, and a second motor fixedly installed on the top wall of the fixing block and whose output end is connected to the stirring rod.

[0014] Through the above structure, the present invention uses a motor to drive the stirring rod to rotate, which in turn drives the stirring blades to stir the raw materials, so as to make the raw materials evenly mixed.

[0015] Preferably, a discharge pipe is fixedly installed at the bottom of the reactor body, a valve is provided on the surface of the discharge pipe, and a feed pipe is fixedly installed on one side of the top of the cover, with a sealing cap threaded to the top of the feed pipe.

[0016] Through the above structure, this utility model can discharge the coating produced inside the reactor body by setting a discharge pipe, and facilitate the entry of raw materials into the reactor body for processing by setting a feed pipe.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] During the cleaning of the reactor vessel, the cleaning agent is injected into the spray nozzle through the inlet pipe and branch telescopic hose. Simultaneously, the power mechanism drives the rotating sleeve to rotate back and forth, thereby rotating the shell and the spray nozzle. This causes the sprayed cleaning agent to rotate and diffuse onto the inner wall of the reactor vessel. At the same time, the rubber wheel rotates along the annular shell, driving the lead screw to rotate, causing the slider to move the spray nozzle back and forth to diffuse and reduce the spray. Then, the electric push rod drives the cleaning scraper to move and contact the inner wall of the reactor vessel. The cleaning scraper can easily scrape off the residue on the inner wall of the reactor vessel. Therefore, the combined use of sprayed cleaning agent and cleaning scraper achieves a highly efficient cleaning effect on the inner wall of the reactor vessel, avoiding the situation where stubborn raw materials are left behind when relying solely on the cleaning scraper. It also prevents raw materials from remaining on the cleaning scraper, ensuring thorough cleaning and effectively improving the use effect of the reactor vessel and the quality and efficiency of coating production.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example

[0028] Please see Figure 1 - Figure 5 This utility model provides a polymer reactor for acrylic resin coatings, comprising: a reactor body 1 and a cover 22 bolted to its top; a stirring mechanism is provided inside the reactor body 1; a rotating sleeve 2 rotatably connected to the top of the cover 22, the rotating sleeve 2 being rotated by a power mechanism provided on the cover 22; four housings 3 fixedly installed on the surface of the rotating sleeve 2; a lead screw 4 rotatably connected between the two sides of the inner wall of the housing 3, one end of the lead screw 4 passing through the housing 3, and rotating with the rotating sleeve 2 through a linkage mechanism provided in the cover 22; a slider 5 threadedly connected to the surface of the lead screw 4 and slidably connected to the housing 3; a spray cylinder 6 fixedly installed at the bottom of the slider 5, the surface of the spray cylinder 6 being equipped with a nozzle; two inlet pipes 15 symmetrically installed through the top of the cover 22; the four spray cylinders 6 being connected in pairs to the two inlet pipes 15 respectively through branch telescopic hoses; two electric push rods 7 symmetrically fixedly installed on the surface of the rotating sleeve 2 and located below the housing 3; and a cleaning scraper 8 fixedly connected to the output end of the electric push rods 7.

[0029] The linkage mechanism includes an annular shell 9 fixedly installed on the inner wall of the cover 22, a rubber wheel 10 fixedly connected to one end of the screw 4 and pressed against the top of the annular shell 9, a connecting block 11 fixedly installed at one bottom end of the housing 3, and a rubber wheel 2 12 rotatably connected to one side of the connecting block 11 and pressed against the inner top wall of the annular shell 9. The resultant force between the rubber wheel 2 12 and the rubber wheel 10 is zero, causing the two to clamp the annular shell 9.

[0030] The technical solution provided in this embodiment is as follows: When using acrylic resin coatings in production, the raw materials inside the reactor body 1 are stirred and mixed by a stirring mechanism. After the coating production is completed, when cleaning the inside of the reactor body 1, the inlet pipe 15 is connected to an external liquid delivery component, so that the cleaning agent (such as environmentally friendly biodegradable cleaning agent and sodium hydroxide solution, etc.) is injected into the spray cylinder 6 through the inlet pipe 15 and the branch telescopic hose. At the same time, the power mechanism drives the rotating sleeve 2 to rotate back and forth (to avoid the branch telescopic hose, etc. from getting tangled), thereby driving the shell 3 and the spray cylinder 6 to rotate, so that the sprayed cleaning agent can be rotated and diffused onto the inner wall of the reactor body 1 to ensure the spraying range. At the same time, during the rotation of the shell 3, the rubber wheel 10 and the rubber wheel 12 can be driven to rotate along the annular shell 9, thereby driving the rubber wheel 10 to drive the filament The rod 4 rotates, and the lead screw 4 drives the slider 5 to move back and forth inside the housing 3, so as to drive the spraying cylinder 6 to move back and forth to spread and reduce the spray, ensuring the uniformity of the spray. After the cleaning agent dissolves the coating for a period of time, the electric push rod 7 drives the cleaning scraper 8 to move and contact the inner wall of the reactor body 1. The power mechanism drives the rotating sleeve 2 and the cleaning scraper 8 to rotate, so that the cleaning scraper 8 can easily scrape off the residue on the inner wall of the reactor body 1. Finally, clean water is introduced into the spraying cylinder 6 to rinse the inner wall of the reactor body 1. Therefore, the inner wall of the reactor body 1 is cleaned efficiently, avoiding the situation where stubborn raw material residue is easily caused by relying solely on the cleaning scraper 8. It can also prevent raw material residue from remaining on the cleaning scraper 8, ensuring the thoroughness of the cleaning, and effectively improving the use effect of the reactor body 1 and the quality and efficiency of the coating.

[0031] Furthermore, the power mechanism includes a motor 13 fixedly mounted on one side of the top of the cover 22, and two meshing gears 14 fixedly mounted on the output end of the motor 13 and the surface of the rotating sleeve 2, respectively.

[0032] Specifically, during the cleaning process of the inner wall of the reactor body 1, the motor 13 rotates in both directions and drives the rotating sleeve 2 to rotate back and forth under the action of the two gears 14, thereby driving the shell 3 and the spraying cylinder 6 to rotate, so that the cleaning agent sprayed from the spraying cylinder 6 can be spread and sprayed on the inner wall of the reactor body 1 to ensure the spraying range. At the same time, the lead screw 4 can rotate with the rotating sleeve 2 through the linkage mechanism, so as to drive the spraying cylinder 6 to move back and forth to spread and shrink, ensuring the uniformity of spraying.

[0033] Furthermore, the stirring mechanism includes a stirring rod 16 rotatably connected to the rotating sleeve 2 via a bearing, a plurality of stirring blades 17 fixedly installed on the surface of the stirring rod 16, a fixing block 18 fixedly installed on the cover 22, and a motor 19 fixedly installed on the inner top wall of the fixing block 18 and whose output end is connected to the stirring rod 16.

[0034] Specifically, during the operation of the reactor body 1, the stirring rod 16 is driven to rotate by the motor 2 19. Since the stirring rod 16 and the rotating sleeve 2 are rotatably connected, the rotating sleeve 2 will not rotate with the stirring rod 16, and vice versa. Thus, the stirring rod 16 can drive the stirring blade 17 to rotate and stir the raw materials so that the raw materials are evenly mixed.

[0035] Furthermore, a discharge pipe 20 is fixedly installed at the bottom of the reactor body 1, and a valve is provided on the surface of the discharge pipe 20. A feed pipe 21 is fixedly installed on one side of the top of the cover 22, and a sealing cap is threaded to the top of the feed pipe 21.

[0036] Specifically, by setting the valve on the discharge pipe 20 to open, the coating produced inside the reactor body 1 can be discharged through the discharge pipe 20. By opening the sealing cover on the feed pipe 21, the raw materials can be easily fed into the reactor body 1 through the feed pipe 21 for processing.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
