Description

Technical Field

[0001] This utility model relates to the field of water-based coating production technology, specifically to a reaction device for producing water-based coatings. Background Technology

[0002] Water-based coatings are widely used in the construction and industrial fields due to their environmentally friendly and safe characteristics. The core of their production lies in the reaction device, which completes the mixing, dispersion and chemical reaction of raw materials in a closed container to ensure product stability and performance.

[0003] Traditional reaction equipment for producing water-based coatings mainly includes a reaction vessel. The raw materials are mixed by a stirring device inside the vessel, and the reaction temperature is controlled by a heating or cooling system to complete the initial preparation of water-based coatings and provide basic support for coating production.

[0004] However, traditional devices have certain limitations in practical use. Operators usually need to manually open the valves outside the reactor to guide the material into the external container. However, frequent valve opening and closing can easily introduce air or impurities, disrupting the sealed reaction environment inside the reactor and affecting the stability of the coating quality. Moreover, manual operation makes it difficult to control the sampling volume, and improper operation can easily lead to continuous leakage of material, causing waste and pollution. In addition, inconsistent sample quantities affect the accuracy and comparability of subsequent test results, making it difficult to truly reflect the state of the material inside the reactor. Therefore, a reaction device for producing water-based coatings is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] See attached document Figure 1-7 A reaction apparatus for producing water-based coatings, comprising: Reactor 1 consists of a vessel body, a drive motor, a stirring shaft, stirring blades, and a jacket structure. During the production of water-based coatings, raw materials are fed into the vessel through the inlet. The stirring and heating devices are then activated to ensure the raw materials react fully at a suitable temperature. Continuous stirring during the reaction ensures uniformity. After the reaction, subsequent processes such as filtration and color adjustment are performed to ultimately obtain a qualified water-based coating product. The drive motor utilizes existing mature technology and is connected to the stirring shaft via a coupling or reducer, providing a stable rotation speed for the stirring blades within reactor 1. This achieves forced convection and efficient mixing of the materials, ensuring uniform reaction. A sampling component is installed at the bottom of reactor 1, comprising: A connecting cylinder 2 is fixedly installed at the bottom of the reactor 1. A through groove 201 is provided between the top of the connecting cylinder 2 and the reactor 1. A discharge port 202 is provided at the bottom of the connecting cylinder 2, which is a channel for the material to be transferred from the reactor 1 to the sampling point. The material enters the connecting cylinder 2 through the through groove 201 and flows out through the discharge port 202 for sampling. A sealing gasket is provided between the through groove 201 and the rotating roller 3 to reduce the phenomenon of material leakage. A rotating roller 3 is rotatably connected to the inner cavity of the connecting cylinder 2. The outer peripheral wall of the rotating roller 3 is provided with a storage tank 302 for receiving material from the through groove 201 during rotation. The volume of the storage tank 302 is fixed, which promotes the consistency of the sampling amount each time. The inner wall of the storage tank 302 is coated with an anti-stick layer to reduce the phenomenon of material adhering to the inner wall of the storage tank 302. The rotating roller 3 rotates in the connecting cylinder 2. When the storage tank 302 rotates to be opposite to the through groove 201, it receives material from the reactor 1. It continues to rotate. When the storage tank 302 rotates to be opposite to the discharge port 202, the material falls from the storage tank 302 into the discharge port 202. A support rod 5 and a support plate 4 are fixedly installed at the bottom of the reactor 1. The sample storage container is placed on top of the support plate 4 to support the sample storage container and facilitate the receipt of coating samples.

[0020] A drive shaft 301 is fixedly installed inside the rotating roller 3, and the drive shaft 301 extends through the connecting cylinder 2 to the inner cavity of the support rod 5, transmitting external driving force to the rotating roller 3. When the drive shaft 301 is rotated, it drives the rotating roller 3 to rotate together.

[0021] A half gear 6 is fixedly installed on the outer wall of the drive shaft 301. A transmission rack 601 is slidably connected to the inner cavity of the support rod 5, and the transmission rack 601 meshes with the outer wall of the half gear 6. The transmission rack 601 slides up and down in the support rod 5, driving the half gear 6 to rotate, which in turn drives the drive shaft 301 to rotate, thereby adjusting the position of the storage tank 302. The movement of the transmission rack 601 drives the half gear 6 to rotate 180 degrees.

[0022] A connecting rod 602 is fixedly installed at the bottom of the transmission rack 601, and the bottom of the connecting rod 602 extends through the support rod 5 into the support plate 4 to extend the point of action of the transmission rack 601.

[0023] The support plate 4 has a groove at the top, and a push plate 401 is slidably connected to the inner wall of the groove. An extension block 402 is fixedly installed on the outer wall of the push plate 401, and the extension block 402 is fixedly connected to the connecting rod 602. In use, the container is placed on the support plate 4, and the push plate 401 is pushed downward by the weight of the container and the pressure of the user's hand. The downward-moving push plate 401 drives the extension block 402 to move downward. The downward-moving extension block 402 pulls the connecting rod 602 downward, which drives the transmission rack 601 to move downward, thereby driving the half gear 6 to rotate, causing the drive shaft 301 and the rotating roller 3 to rotate, thereby causing the storage tank 302 to rotate downward, so that the material in the storage tank 302 is put into the container.

[0024] The inner cavity of the support rod 5 has an arc-shaped groove 604, and a slider 603 is engaged with the inner wall of the arc-shaped groove 604. The slider 603 is fixedly connected to the half gear 6. A spring strip 605 is fixedly installed on the inner wall of the arc-shaped groove 604, and the other end of the spring strip 605 is fixedly connected to the slider 603. In the natural state, the spring strip 605 pushes the slider 603 to move upward along the inner wall of the arc-shaped groove 604. After sampling is completed, the user removes the container storing the material from the support plate 4. At this time, the push plate 401 has no pressure, and the pushing force of the spring strip 605 pushes the slider 603 to reset, thereby driving the drive shaft 301 and the rotating roller 3 to rotate back, so that the storage tank 302 is realigned with the upper through groove 201, ready for the next sampling.

[0025] Working principle: In use, firstly, the raw materials are fed into the reactor 1 through the feed inlet. The drive motor is turned on to rotate the stirring shaft and the stirring blades. Simultaneously, by controlling the reaction temperature, the raw materials are fully mixed, dispersed, and reacted under suitable conditions to form a uniform water-based coating base. When it is necessary to sample and test the material in the reactor, the operator places the sample storage container on top of the push plate 401. During the placement of the container, its gravity will press down on the push plate 401. The push plate 401 pulls the connecting rod 602 downward through the extension block 402, which in turn drives the transmission rack 601 fixed thereto to slide downward in the inner cavity of the support rod 5. The transmission rack 601 drives the half gear 6 meshing with it to rotate 180 degrees. The half gear 6 drives the drive shaft 301 and the rotating roller 3 fixed thereto to rotate synchronously. The material storage groove 302 on the outer wall of the rotating roller 3 is aligned with the upper through groove 20. The material receiving position 1 is rotated to the unloading position aligned with the discharge port 202 below. During this rotation, the quantitative material pre-stored in the storage tank 302 has a fixed volume and is discharged by gravity with the assistance of the anti-stick layer, accurately falling into the sample container below through the discharge port 202. This achieves precise and sealed sampling, effectively avoiding the problems of air introduction, pollution, leakage, and inconsistent sampling volume caused by frequent opening of traditional valve sampling. After sampling is completed, the operator removes the sample container from the support plate 4, and the push plate 401 loses pressure. At this time, the compressed spring strip 605 releases elastic potential energy, pushing the slider 603 to slide upward and reset along the inner wall of the arc groove 604, thereby driving the half gear 6, drive shaft 301 and rotating roller 3 to rotate 180 degrees in the opposite direction, so that the storage tank 302 is aligned with the through groove 201 again to receive new material and prepare for the next sampling.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
