Description

Technical Field

[0001] This utility model relates to the technical field of paint baking heating equipment, and in particular to a heating reaction equipment for the production of amino paint. Background Technology

[0002] Amino paint is composed of amino resin, alkyd resin, pigments, fillers, solvents and additives. In the production process, it is often necessary to heat the raw materials through heating reaction equipment to promote the chemical reaction between the components, thereby obtaining high-performance amino paint products.

[0003] For example, Chinese patent CN215695524U discloses a heating device for high-solids amino baking paint, including a main body. A reciprocating screw is rotatably connected inside the main body. Two sets of limiting plates are fixed on both sides of the reciprocating screw. A movable plate that contacts the limiting plates is sleeved on the outer wall of the reciprocating screw. A triangular strip set is fixed on the inner wall of the main body. A spiral copper tube is wound inside the main body. One end of the spiral copper tube extends into the interior of the main body and is provided with a smoke exhaust pipe. A water tank is provided inside the main body. The other end of the spiral copper tube is provided with an L-shaped pipe that extends into the interior of the water tank.

[0004] Existing heating reaction equipment for amino paint production only heats the bottom of the reaction vessel, resulting in uneven heating, incomplete reaction, and poor quality of the amino paint. In addition, during the heating process, the raw materials of amino paint may coke due to local overheating or prolonged heating, especially at the bottom or around the side walls of the reaction vessel. Due to heat accumulation, the material is prone to forming coke lumps. These coke lumps not only reduce the yield of amino paint but may also mix into the product, affecting its appearance and quality. To address the above problems, a heating reaction equipment for amino paint production is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art, and to propose a heating reaction device for the production of amino paint.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heating reaction device for the production of amino paint, comprising a heating mechanism and a stirring mechanism. The heating mechanism includes a heater, a heat transfer oil heating tank, a spiral heat transfer pipe, a circulating pump, a reaction vessel body, and an electric heating wire. A heat insulation shell is provided on the outer wall of the reaction vessel body, and an electric heating wire is provided between the heat insulation shell and the reaction vessel body. The electric heating wire is evenly wound on the outer wall of the reaction vessel body. The spiral heat transfer pipe is spirally distributed at the bottom of the reaction vessel body and is connected to the heat transfer oil heating tank through the circulating pump. The stirring mechanism includes a top cover, a toothed ring, a motor, a rotating rod, and two scrapers. The motor is installed at the top of the reaction vessel body, and the rotating rod is connected to the output shaft of the motor. The rotating rod passes through the top of the reaction vessel body and extends to the bottom of the reaction vessel body. Two sets of extension plates are symmetrically fixedly connected to the outer edge of the rotating rod. The two sets of extension plates are connected to each other through scrapers, and the scrapers are in close contact with the side wall of the reaction vessel body. The extension plate at the bottom is in close contact with the bottom wall of the reaction vessel body.

[0007] Preferably, the bottom of the top cover is fixedly installed to the top of the reactor body, and the toothed ring is fixed to the top of the top cover.

[0008] Preferably, a movable rod is rotatably connected between the two sets of extension plates, and a gear is fixedly connected to the top of the movable rod through the top cover, with the outer edge of the gear meshing with the inner edge of the gear ring.

[0009] Preferably, a stirring rod is symmetrically and fixedly connected to the bottom end of the movable rod, and multiple stirring blades are uniformly and fixedly connected between the stirring rod and the movable rod.

[0010] Preferably, the top of the top cover is fixedly connected to a feeding pipe, and the bottom of the top cover is fixedly connected to a discharge pipe.

[0011] Preferably, a control valve is fixedly connected to one end of the discharge pipe, and a support frame is fixedly installed on the outer side of the bottom of the heat insulation shell.

[0012] Preferably, the heater is fixedly installed on the outside of the heat-insulating shell.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the heater initially heats the reactor body through an electric heating wire to bring it to a certain temperature. When the reactor body temperature approaches the set value, the heat transfer oil circulates in the spiral heat transfer tube under the action of the circulating pump. By combining the electric heating wire with the circulating heat transfer oil, and by setting a heat insulation shell on the outer wall of the reactor body, uniform heating of the materials in the reactor body is achieved, improving energy utilization and effectively solving the problems of uneven heating and energy waste. This is beneficial to improving the quality of amino paint and reducing production costs.

[0015] 2. In this utility model, by setting up a stirring assembly, a motor drives a rotating rod, an extension plate, and a scraper to rotate. The scraper is in close contact with the side wall of the reactor body, and the extension plate at the bottom is in close contact with the bottom wall of the reactor body. While stirring the material in the reactor body, the scraper and extension plate scrape up the material adhering to the bottom and side walls of the reactor body, preventing the material adhering to the bottom and side walls of the reactor body from coking due to localized prolonged heating, thus improving the production quality of amino paint. In addition, the stirring rod and multiple stirring blades revolve around the rotating rod while rotating on their own axis. Through the synergistic action of the scraper, extension plate, and multiple stirring blades, the raw materials in the reactor body can be fully mixed, improving the reaction efficiency.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a heating reaction device for the production of amino paint, including a heating mechanism 1 and a stirring mechanism 2. The heating mechanism 1 includes a reaction vessel body 19, a heater 12, a heat transfer oil heating tank 14, a spiral heat transfer pipe 15, a circulating pump 17, and an electric heating wire 110. A heat insulation shell 11 is provided on the outer wall of the reaction vessel body 19, and an electric heating wire 110 is provided between the heat insulation shell 11 and the reaction vessel body 19. The electric heating wire 110 is evenly wound on the outer wall of the reaction vessel body 19. The spiral heat transfer pipe 15 is spirally distributed at the bottom of the reaction vessel body 19 and is connected to the heat transfer oil heating tank 14 through the circulating pump 17. The stirring mechanism 2 includes a top cover 21, a toothed ring 22, a motor 24, a rotating rod 25, and two scrapers 27. 24 is installed on the top of the reactor body 19. The rotating rod 25 is connected to the output shaft of the motor 24. The rotating rod 25 passes through the top of the reactor body 19 and extends to the bottom of the reactor body 19. Two sets of extension plates 26 are symmetrically fixedly connected to the outer edge of the rotating rod 25. The two sets of extension plates 26 are connected by scrapers 27. The scrapers 27 are close to the side wall of the reactor body 19. The extension plate 26 at the bottom is close to the bottom wall of the reactor body 19. The top of the top cover 21 is fixedly connected to the feeding pipe 23, and the bottom of the top cover 21 is fixedly connected to the discharge pipe 16. One end of the discharge pipe 16 is fixedly connected to the control valve 18. The bottom outer side of the heat insulation shell 11 is fixedly installed with a support frame 13. The heater 12 is fixedly installed on the outer side of the heat insulation shell 11.

[0025] The specific settings and functions of this embodiment are described below: Open the cover of the feeding pipe 23, and add the various raw materials required for the production of amino paint into the reaction vessel 19 according to the formula ratio. Close the cover of the feeding pipe 23, start the control system, and set the required temperature parameters for the reaction on the operation panel. First, start the heater 12. The heater 12 uses the electric heating wire 110 to initially heat the reaction vessel 19, allowing it to reach a certain temperature. When the temperature of the reaction vessel 19 approaches the set value, start the heat transfer oil heating tank 14 and the circulating pump 17. The heat transfer oil... Under the action of the circulating pump 17, the material circulates in the spiral heat-conducting pipe 15 to uniformly heat the bottom of the reactor body 19, ensuring that the material inside the reactor body 19 is heated evenly. By combining electric heating wire 110 with heat-conducting oil circulation heating, and by setting a heat-insulating shell 11 (the heat-insulating shell 11 is made of ceramic fiber material) on the outer wall of the reactor body 19, uniform heating of the material inside the reactor body 19 is achieved, improving energy utilization efficiency and effectively solving the problems of uneven heating and energy waste. This is beneficial to improving the quality of amino paint and reducing production costs.

[0026] Simultaneously, while heating the material, the stirring mechanism 2 is activated. The stirring motor 24 drives the rotating rod 25, the extension plate 26, and the scraper 27 to rotate, stirring and mixing the raw materials in the reactor body 19. At the same time, the scraper 27 is in close contact with the side wall of the reactor body 19, and the extension plate 26 at the bottom is in close contact with the bottom wall of the reactor body 19. While stirring the material in the reactor body 19, the scraper 27 and the extension plate 26 scrape up the material adhering to the bottom and side wall of the reactor body 19, preventing the material adhering to the bottom and side wall of the reactor body 19 from coking due to localized prolonged heating, thus improving the production quality of amino paint.

[0027] Example 2: Figure 4 and Figure 5 As shown, the bottom of the top cover 21 is fixedly installed with the top of the reactor body 19, the toothed ring 22 is fixed to the top of the top cover 21, and the two sets of extension plates 26 are rotatably connected with movable rods 28. The top of the movable rod 28 passes through the top cover 21 and is fixedly connected with a gear 29, and the outer edge of the gear 29 meshes with the inner edge of the toothed ring 22. The bottom end of the movable rod 28 is symmetrically fixedly connected with stirring rods 210, and multiple stirring blades 211 are evenly fixedly connected between the stirring rod 210 and the movable rod 28.

[0028] The overall effect of this embodiment is that, while the rotating rod 25 and the extension plate 26 rotate, the movable rod 28 rotates, thereby driving the top gear 29 to rotate around the rotating rod 25. The outer wall of the gear 29 meshes with the inner wall of the gear ring 22. Therefore, the movable rod 28 can rotate on its own axis while rotating around the rotating rod 25, so that the stirring rod 210 and multiple stirring blades 211 can rotate on their own axis while revolving around the rotating rod 25. Through the synergistic action of the scraper 27, the extension plate 26 and the multiple stirring blades 211, the raw materials in the reactor body 19 can be fully mixed, improving the reaction efficiency. When the reaction is completed, the heating mechanism 1 and the stirring mechanism 2 are stopped, and the discharge pipe 16 is opened through the control valve 18 to discharge the reacted amino paint product from the reactor body 19.

[0029] The method of use and working principle of this device: Various raw materials required for the production of amino paint are put into the reaction vessel 19 according to the formula ratio. The heater 12 is started. The heater 12 initially heats the reaction vessel 19 through the electric heating wire 110. When the temperature of the reaction vessel 19 approaches the set value, the heat transfer oil circulates in the spiral heat transfer tube 15 under the action of the circulation pump 17. Through the combination of electric heating wire 110 and heat transfer oil circulation heating, and the heat insulation shell 11 set on the outer wall of the reaction vessel 19, uniform heating of the materials in the reaction vessel 19 is achieved, thereby improving the quality of amino paint and reducing production costs.

[0030] Simultaneously, while heating the material, the stirring mechanism 2 is activated. The scraper 27 is in close contact with the side wall of the reactor body 19, and the extension plate 26 at the bottom is in close contact with the bottom wall of the reactor body 19. While stirring the material in the reactor body 19, the scraper 27 and the extension plate 26 scrape up the material adhering to the bottom and side wall of the reactor body 19 to prevent the material from coking due to prolonged local heating. At the same time, the stirring rod 210 and multiple stirring blades 211 revolve around the rotating rod 25 while rotating on their own axis. Through the synergistic action of the scraper 27, the extension plate 26 and the multiple stirring blades 211, the raw materials in the reactor body 19 can be fully mixed, improving the reaction efficiency.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
