Description

Technical Field

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

[0002] The amino paint mixing reaction device is used in the continuous production process of amino paint to mix various raw materials and allow them to undergo a chemical reaction in order to prepare amino paint products that meet quality requirements. The stirred tank is the main reaction site.

[0003] For example, CN222659158U discloses a high-efficiency low-temperature baking equipment for the production of water-based acrylic amino paint, including a fixed base plate, a baking oven fixedly connected to the top of the fixed base plate, a cabinet door hinged to the front of the baking oven, a heating tube fixedly installed on the top inner side of the baking oven, a cooler fixedly installed on the top inner side of the baking oven, a temperature sensor fixedly installed on the side inner wall of the baking oven, a rotating mechanism set inside the baking oven, and a fan mechanism set above the rotating mechanism.

[0004] However, in the existing technology, during the reaction process, some components in the material will form scale on the inner wall of the reactor if the reaction is insufficient. The scale will affect the heat transfer efficiency and make it difficult to control the temperature. Once the scale is loosened, it will mix into the product, affecting the product quality and generating solid impurities. These impurities and undissolved materials can easily block pipes, valves and discharge ports, affecting the continuity of production and, in severe cases, causing equipment damage. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that some components in the material will form scale on the inner wall of the reactor when the reaction is insufficient. The scale will affect the heat transfer efficiency and make it difficult to control the temperature. Once the scale is loosened, it will mix into the product, affecting the product quality and generating solid impurities. Therefore, a mixing reaction device for continuous production of amino paint is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mixing reaction device for continuous production of amino paint, comprising a reaction vessel body, wherein a cleaning component is fixedly installed on the top of the reaction vessel body;

[0007] The cleaning assembly includes a rack, a reinforcing rod, and a cleaning ring. One end of the reinforcing rod is fixedly connected to the bottom of the rack. The axis of the rack coincides with the axis of the reactor body. A connecting gear is meshed on one side of the rack. The edge of the cleaning ring is attached to the inner wall of the reactor body.

[0008] Preferably, a support platform is fixedly installed on the top of the reactor body, and a first servo motor is fixedly installed at both ends of the support platform.

[0009] Preferably, a support plate is fixedly installed on one side of the support platform, and a second servo motor is fixedly installed on one side of the top of the support plate.

[0010] Preferably, a worm gear is fixedly connected to the output end of the second servo motor, and the worm gear is located on one side of the connecting gear.

[0011] Preferably, a worm gear is fixedly installed on one side of the connecting gear, and the worm gear meshes with the worm.

[0012] Preferably, an arc-shaped plate is fixedly installed on one side of the bottom of the support plate, and the connecting gear and worm gear are rotatably connected to the two arc-shaped plates respectively.

[0013] Preferably, during the reaction process, some components in the material may form scale on the inner wall of the reactor if the reaction is insufficient. Scale will affect the heat transfer efficiency and make it difficult to control the temperature. Once the scale is loosened, it will mix into the product, affecting the product quality and generating solid impurities.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, a cleaning component is provided to scrape off residual materials on the inner wall of the reactor. During the production process, the toothed rod can drive the cleaning ring to move up and down. The friction between the cleaning ring and the reactor body cleans off the materials on the inner wall and scrapes the materials into the reactor body to allow them to react fully, preventing these substances from forming scale on the inner wall of the reactor. This avoids the problem of the structure affecting the heat transfer efficiency. Without the formation of scale, there will be no problem of scale mixing into the product.

[0016] 2. In this utility model, by setting a worm gear and worm transmission structure, the second servo motor can drive the worm gear through the worm during use, and use the connecting gear on the side of the worm gear to mesh with the rack to achieve the purpose of pushing the cleaning ring. This structure uses the self-locking function of the worm gear and worm to ensure the stability of the rack. Attached Figure Description

[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 2 , Figure 3 and Figure 4 As shown, this utility model provides a mixing reaction device for continuous production of amino paint, including a reaction vessel body 1, and a cleaning component 2 is fixedly installed on the top of the reaction vessel body 1;

[0025] The cleaning assembly 2 includes a rack 21, a reinforcing rod 26, and a cleaning ring 27. One end of the reinforcing rod 26 is fixedly connected to the bottom of the rack 21. The axis of the rack 21 coincides with the axis of the reactor body 1. A connecting gear 24 is meshed on one side of the rack 21. The edge of the cleaning ring 27 is attached to the inner wall of the reactor body 1. A support platform 3 is fixedly installed on the top of the reactor body 1. A first servo motor 4 is fixedly installed at both ends of the support platform 3.

[0026] The specific settings and functions of this embodiment are described below. The raw materials of amino paint are concentrated inside the reaction vessel body 1 for reaction. During use, the stirring rod at the output end of the first servo motor 4 can stir the material to allow it to react fully. The reaction vessel body 1 is equipped with a jacket, and circulating hot water or hot oil can be introduced into the jacket to precisely control the reaction temperature.

[0027] The rack 21 meshes with the connecting gear 24. During the processing, the connecting gear 24 meshes with the rack 21 and moves up and down, thereby driving the cleaning ring 27 to rub against the reactor body 1. This friction can remove some unreacted material that is stuck to the inner wall of the reactor, allowing it to be mixed with the material again, so as to ensure that all materials can react fully and avoid scaling on the inner wall of the reactor body 1.

[0028] The cleaning ring 27 is fixedly connected to the rack 21 by the reinforcing rod 26. The reinforcing rod 26 can ensure the structural stability of the cleaning ring 27 without affecting the use of the stirring rod. The support platform 3 can determine the position of the first servo motor 4 and the rack 21.

[0029] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, a support plate 22 is fixedly installed on one side of the support platform 3. A second servo motor 23 is fixedly installed on one side of the top of the support plate 22. A worm gear 28 is fixedly connected to the output end of the second servo motor 23. The worm gear 28 is located on one side of the connecting gear 24. A worm wheel 25 is fixedly installed on one side of the connecting gear 24. The worm wheel 25 meshes with the worm gear 28. An arc plate 29 is fixedly installed on one side of the bottom of the support plate 22. The connecting gear 24 and the worm wheel 25 are rotatably connected to the two arc plates 29 respectively. A groove 210 is provided on one side of the rack 21. The rack 21 is slidably connected to the support plate 22 through the groove 210.

[0030] The overall effect of this embodiment is that the second servo motor 23 is fixedly mounted on the support plate 22, and its output end is fixedly connected to a worm gear 28. The worm gear 28 is meshed with the worm wheel 25 on the side of the connecting gear 24. During the operation of the second servo motor 23, the meshing of the worm gear 28 and the worm wheel 25 drives the connecting gear 24, thereby achieving the purpose of pushing the rack 21 to move up and down.

[0031] The rack 21 is slidably connected to the support plate 22 through the groove 210 on the side, which can prevent the rack 21 from rotating and ensure that the whole can transmit normally. The connecting gear 24 and the worm gear 25 are respectively rotatably mounted on the two arc plates 29, which can ensure their own structural stability.

[0032] The method of use and working principle of this device: The raw materials of amino paint are concentrated inside the reaction vessel body 1 for reaction. When in use, the stirring rod at the output end of the first servo motor 4 can stir the material to allow it to react fully. The reaction vessel body 1 is equipped with a jacket, and circulating hot water or hot oil can be introduced into the jacket to precisely control the reaction temperature.

[0033] During the processing, the second servo motor 23 drives the worm gear 28, which in turn drives the connecting gear 24 via the worm wheel 25. This causes the connecting gear 24 to mesh with the rack 21 and move up and down, thereby causing the cleaning ring 27 to rub against the reactor body 1. This friction removes some unreacted material that adheres to the inner wall of the reactor, allowing it to be mixed with the other materials to ensure that all materials can react fully and prevent scale buildup on the inner wall of the reactor body 1.

[0034] 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.
