Description

Technical Field

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

[0002] In the preparation process of water-based coatings, the reaction vessel is a key piece of equipment. It provides a place for the various components of the coating to mix and react, ensuring the uniformity and stability of the coating and meeting the performance requirements of water-based coatings in different scenarios.

[0003] Traditional water-based coatings use reaction vessels that rely primarily on stirring devices to mix the internal materials. During the stirring process, the materials continuously tumble within the reaction vessel to achieve a uniform mixture, thus completing the subsequent coating preparation process.

[0004] However, traditional reaction vessels still have certain shortcomings in practical use. During stirring, some materials tend to float on the liquid surface and form clumps. These unfused clumps can lead to incomplete reactions, affecting the uniformity of the coating and the quality of the final product. Moreover, traditional reaction vessels, relying solely on the stirring shaft, cannot effectively carry the surface clumps into the liquid phase. The only possible solution is to extend the stirring time, which not only prolongs the mixing time and increases energy consumption but also reduces overall production efficiency, placing significant cost pressure on enterprises. Therefore, a reaction vessel for water-based coatings is proposed to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a reaction vessel for water-based coatings, which can effectively solve the problems in the existing technology where some materials tend to float on the liquid surface and form clumps. These unfused clumps will lead to incomplete reaction, affecting the uniformity of coatings and the quality of the final product. The present invention also addresses the problem that traditional reaction vessels rely solely on the stirring shaft to effectively carry the surface clumps into the liquid phase.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a reaction vessel for water-based coatings, comprising: The reactor body includes a processing chamber and an operating chamber inside. A mixing shaft for stirring materials is rotatably mounted within the reactor body. The operating chamber contains a pushing assembly for pushing unblended material clumps floating on the liquid surface into the liquid. This pushing assembly includes: A push plate, with a connecting pipe fixedly installed on its top, and the connecting pipe is slidably sleeved on the outer wall of the mixing shaft; The moving unit includes a drive motor, a rotating disk, and a transmission component. The drive motor is fixedly installed on the outer wall of the reactor body. A rotating shaft is fixedly provided at the output end of the drive motor and is fixedly connected to the rotating disk. The transmission component is connected between the rotating disk and the connecting pipe to convert the rotational motion of the rotating disk into the axial reciprocating motion of the connecting pipe along the mixing shaft, thereby driving the push plate to move up and down.

[0007] Preferably, the transmission component includes a push rod and a fixed plate. The push rod is eccentrically fixed to the outer wall of the rotating disk, and the fixed plate is fixedly installed on the top of the connecting pipe. An axial sliding groove is provided on the outer wall of the fixed plate, and the push rod is movably engaged in the sliding groove.

[0008] Preferably, a limiting rod is fixedly provided on the top of the push plate, and the top of the limiting rod extends through the operating chamber into the processing chamber.

[0009] Preferably, a fixing rod is fixedly installed inside the processing chamber, and a connecting groove is opened at the bottom of the fixing rod. A sliding plate is movably engaged with the inner wall of the connecting groove, and the sliding plate is fixedly connected to the limiting rod.

[0010] Preferably, a wrapping pad is fixedly provided at the top of the inner cavity of the treatment chamber, and the wrapping pad is movably sleeved on the outer wall of the limiting rod.

[0011] Preferably, the outer wall of the pusher plate has a through hole, and a feed pipe is fixedly installed on the main body of the reactor, with the feed pipe extending into the processing chamber through the through hole.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: In this invention, a moving unit consisting of a drive motor, a rotating disk, a push rod, and a connecting pipe with a sliding groove is provided. This unit, along with a push plate that can slide along the mixing axis, effectively compresses unblended material clumps floating on the surface of the liquid in the processing chamber into the liquid, ensuring the clumps fully contact the liquid and participate in the reaction. This solves the problem of traditional reactors where stirring alone is insufficient to bring surface clumps into the liquid phase, improving material mixing and reaction completeness, reducing stirring time, lowering energy consumption, and increasing production efficiency. Simultaneously, the limiting rod and fixing rod work together to restrict the push plate's rotation, and the padding prevents material leakage, ensuring stable operation of the reactor.

[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 1-5 A reaction vessel for water-based coatings, comprising: The reactor body 1 contains a processing chamber 101 and an operating chamber 102. The processing chamber 101 is where water-based coating materials are mixed, reacted, and subsequently processed. The operating chamber 102 provides space for the installation and operation of auxiliary devices such as the pushing component, ensuring that these devices can function properly and assist in the material processing within the processing chamber 101. A mixing shaft 2 for stirring materials is rotatably installed inside the reactor body 1. This mixing shaft 2 is typically driven by an external rotary motor, which then transmits the rotational motion to the stirring blades. The stirring blades generate stirring force as they rotate within the material, achieving mixing. The operating chamber 102 contains a pushing component for squeezing unblended material clumps floating on the liquid surface into the liquid. This pushing component includes: The pusher plate 4 has a connecting pipe 401 fixedly installed on its top, and the connecting pipe 401 is slidably sleeved on the outer wall of the mixing shaft 2. It is used to squeeze the unfused material clumps floating on the liquid surface of the processing chamber 101 into the liquid, so that the clumps can fully contact the liquid and participate in the reaction, thereby improving the mixing effect and reaction completeness of the material. When the connecting pipe 401 is subjected to the force of the transmission component, since the connecting pipe 401 and the mixing shaft 2 are in sliding fit, the connecting pipe 401 will drive the pusher plate 4 to move up and down along the axial direction of the mixing shaft 2, thereby squeezing the material clumps. The moving unit includes a drive motor 5, a rotating disk 502, and a transmission component. The drive motor 5 is fixedly installed on the outer wall of the reactor body 1. A rotating shaft 501 is fixedly installed at the output end of the drive motor 5. The drive motor 5 is the power source of the entire moving unit, providing power for the rotation of the rotating disk 502. The rotating shaft 501 is fixedly connected to the rotating disk 502. After the drive motor 5 starts, its output shaft drives the rotating shaft 501 to rotate. The rotating shaft 501 then transmits the rotational motion to the rotating disk 502, causing the rotating disk 502 to perform circumferential motion around the rotating shaft 501. The transmission component is connected between the rotating disk 502 and the connecting pipe 401, and is used to convert the rotational motion of the rotating disk 502 into the axial reciprocating motion of the connecting pipe 401 along the mixing shaft 2, thereby driving the push plate 4 to move up and down.

[0020] The transmission components include a push rod 503 and a fixed plate 504. The push rod 503 is eccentrically fixed to the outer wall of the rotating disk 502, and the fixed plate 504 is fixedly installed on the top of the connecting pipe 401. The outer wall of the fixed plate 504 is provided with an axial sliding groove 505. The push rod 503 is movably engaged in the sliding groove 505. When the rotating disk 502 rotates, the eccentrically set push rod 503 makes a circular motion and slides in the sliding groove 505. Since the sliding groove 505 is axially opened, the force applied by the push rod 503 to the inner wall of the sliding groove 505 will cause the fixed plate 504 to drive the connecting pipe 401 to reciprocate along the axial direction of the mixing shaft 2, thereby driving the push plate 4 to move up and down.

[0021] A limiting rod 603 is fixedly installed on the top of the push plate 4. The top of the limiting rod 603 extends through the operating chamber 102 into the processing chamber 101. A fixing rod 6 is fixedly installed inside the processing chamber 101. A connecting groove 601 is opened at the bottom of the fixing rod 6. A sliding plate 602 is movably engaged with the inner wall of the connecting groove 601. The sliding plate 602 is fixedly connected to the limiting rod 603. When the push plate 4 moves up and down under the action of the moving unit, the limiting rod 603 will move up and down accordingly. Since the sliding plate 602 is fixedly connected to the limiting rod 603 and the sliding plate 602 is movably engaged in the connecting groove 601 of the fixing rod 6, the sliding plate 602 can only slide up and down in the connecting groove 601, thereby restricting the rotation of the limiting rod 603, and thus restricting the rotation of the push plate 4.

[0022] A coating pad 604 is fixedly installed at the top of the inner cavity of the processing chamber 101, and the coating pad 604 is movably sleeved on the outer wall of the limiting rod 603. The coating pad 604 has a certain elasticity and sealing performance. It is tightly sleeved on the outer wall of the limiting rod 603. When the limiting rod 603 moves up and down, the coating pad 604 will elastically deform accordingly, always maintaining close contact with the limiting rod 603, thereby preventing the material in the processing chamber 101 from leaking from the gap between the limiting rod 603 and the operating chamber 102, ensuring the sealing of the reactor, and avoiding material waste and environmental pollution.

[0023] The outer wall of the push plate 4 has a through hole, and the main body of the reactor 1 is fixedly equipped with a feed pipe 103. The feed pipe 103 extends into the processing chamber 101 through the through hole. The feed pipe 103 is a channel for conveying water-based coating raw materials into the reactor, ensuring that various raw materials can enter the processing chamber 101 accurately and smoothly, providing a material basis for subsequent mixing and reaction.

[0024] The main body 1 of the reactor is fixedly equipped with a heating tube 3 for heating materials. The heating tube 3 generates heat by being energized and transfers the heat to the surrounding materials. The temperature of the materials is raised through heat conduction and convection to meet the specific temperature conditions required in the preparation of certain water-based coatings, thereby promoting the chemical reaction and improving the reaction efficiency and product quality.

[0025] Working principle: During operation, the operator feeds water-based coating raw materials into the processing chamber 101 through the feed pipe 103. After the materials are fed in, the external rotary motor is started to drive the mixing shaft 2 to rotate for conventional stirring. At the same time, the heating pipe 3 is turned on to provide the required temperature for the reaction. At this time, some light materials tend to float on the liquid surface and form unfused clumps. The operator then starts the drive motor 5, which is fixedly installed on the outer wall of the reactor body 1. The drive motor 5 drives the rotating disk 502 to rotate through the rotating shaft 501, causing the push rod 503, which is eccentrically fixed to its outer wall, to make a circular motion. Because the push rod 503 is axially engaged with the outer wall of the connecting pipe 401... Within the chute 505, the rotational motion is converted into the reciprocating motion of the connecting pipe 401 along the axis of the mixing shaft 2. The connecting pipe 401 drives the push plate 4 at its bottom and the limiting rod 603 at its top to move up and down stably together. The limiting rod 603 restricts rotation by sliding the top slide plate 602 in the connecting groove 601 at the bottom of the fixed rod 6. The coating pad 604 is movably sleeved on the outer wall of the limiting rod 603 to maintain dynamic sealing. The reciprocating motion of the push plate 4 continuously presses the liquid agglomerates into the liquid phase of the treatment chamber 101, so that the agglomerates fully contact the liquid and participate in the reaction, promoting the preparation of a uniform and stable water-based coating product.

[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.
