Description

Technical Field

[0001] This utility model belongs to the field of coating processing technology, and in particular to a chemical reaction vessel for coating preparation. Background Technology

[0002] Coatings are made by mixing special resins, pigments, fillers, curing agents and other additives in a certain proportion, and then preparing them through processes such as hot extrusion, crushing and sieving. In order to mix these coatings and additives, a reaction vessel is needed for stirring. However, most reaction vessels now use a fixed stirring rod, which has limited stirring effect, making it difficult to ensure the uniform distribution of the coating in the reaction vessel, thus affecting the quality of the coating.

[0003] A Chinese patent (authorization announcement number CN206715911U) discloses a coating reaction vessel, which "includes a tank body and a stirring device, and further includes a feeding device, wherein the feeding device includes a storage tank for holding materials and a feeding tank disposed inside the tank body, the feeding tank and the storage tank are connected through a first feeding pipe and a second feeding pipe, and the feeding tank is provided with a cavity."

[0004] It is evident that the cited patent document suffers from the problem of coatings being difficult to distribute evenly within the reactor. Utility Model Content

[0005] The purpose of this invention is to provide a chemical reaction vessel for coating preparation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chemical reaction vessel for coating preparation, comprising a reaction vessel body, a cover plate on the top surface of the reaction vessel body, a drive motor mounted on the top surface of the cover plate, a diamond-shaped rod connected to the output end of the drive motor through the cover plate, a rotating cylinder sleeved around the periphery of the diamond-shaped rod, a plurality of mixing rods for mixing coatings and additives being equidistantly mounted around the periphery of the rotating cylinder, an inverted U-shaped mounting frame mounted on the top surface of the cover plate, an electric push rod mounted on the top surface of the mounting frame, an inverted U-shaped lifting frame connected to the output end of the electric push rod, the bottom surface of the lifting frame penetrating the cover plate and located within the inner cavity of the reaction vessel body, and a rotating moving component mounted on the inner side wall of the lifting frame for driving the rotating cylinder to move longitudinally without affecting its rotation.

[0007] Preferably, the rotating moving assembly includes a connecting plate, a through hole, and a bearing, wherein the connecting plate is installed on the inner walls of both sides of the lifting frame.

[0008] Preferably, the through hole is formed on the top surface of the connecting plate, and the rotating cylinder is positioned at the center of the cavity inside the through hole.

[0009] Preferably, the bearing is disposed in the inner cavity of the through hole, the outer wall of the bearing is connected and fixed to the inner wall of the through hole, and the circumference of the top surface of the rotating cylinder passes through the bearing and is connected and fixed to the inner wall of the bearing.

[0010] Preferably, one end of each of the plurality of mixing rods is connected to a rubber spatula for cleaning the paint residue on the inner wall of the reactor.

[0011] Preferably, a base is installed on the periphery of the reactor body, and two cylinders are installed on the top surface of the base.

[0012] Preferably, two top plates are symmetrically installed on the periphery of the cover plate, and the piston rods of the two cylinders are respectively connected and fixed to the bottom surface of the two top plates.

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

[0014] This chemical reactor for coating preparation provides power to the lifting frame by activating the electric push rod. This power is then used to drive the rotating drum longitudinally via the connecting plate. In conjunction with the drive motor, the diamond-shaped rods rotate, allowing multiple mixing rods to move longitudinally during rotation. Compared to existing devices where the mixing rods are in a fixed position, this device enables the longitudinal movement of multiple mixing rods, thereby improving the mixing effect of coatings and additives.

[0015] By activating the cylinder, power can be provided to move the top plate, allowing the cover plate to detach from the reactor body and clean the interior of the reactor body.

[0016] The rubber spatula connected to multiple mixing rods can remove the paint residue left on the inner wall of the reactor, making it easy to clean up the residue. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 4 The chemical reaction vessel for coating preparation shown includes a reaction vessel body 1, a cover plate 2 on the top surface of the reaction vessel body 1, a feed pipe for adding coating connected to one side of the reaction vessel body 1, a base 14 installed around the reaction vessel body 1, two cylinders 15 installed on the top surface of the base 14, and two top plates 16 symmetrically installed around the cover plate 2. The piston rods of the two cylinders 15 are respectively connected and fixed to the bottom surface of the two top plates 16. By opening the cylinders 15, the top plates 16 can be moved upward, thereby moving the cover plate 2 upward and allowing the cover plate 2 to detach from the reaction vessel body 1, facilitating personnel to clean the inside of the reaction vessel body 1.

[0028] A drive motor 3 is installed on the top surface of the cover plate 2. The output end of the drive motor 3 passes through the cover plate 2 and is connected to a diamond-shaped rod 4. A rotating cylinder 5 is sleeved around the diamond-shaped rod 4. Several mixing rods 6 for mixing coatings and additives are installed at equal intervals around the rotating cylinder 5. After the coatings and additives are added into the reactor body 1, the drive motor 3 is turned on, which drives the diamond-shaped rod 4 to rotate, thereby driving the rotating cylinder 5 to rotate, and then driving the multiple mixing rods 6 to rotate, so as to mix the coatings and additives.

[0029] An inverted U-shaped mounting bracket 7 is installed on the top surface of the cover plate 2. An electric push rod 8 is installed on the top surface of the mounting bracket 7. The output end of the electric push rod 8 is connected to an inverted U-shaped lifting frame 9. The bottom surface of the lifting frame 9 penetrates the cover plate 2 and is located in the inner cavity of the reactor body 1. A rotating moving assembly is installed on the inner side wall of the lifting frame 9 to drive the rotating cylinder 5 to move longitudinally without affecting its rotation. The rotating moving assembly includes a connecting plate 10, a through hole 11, and a bearing 12. The connecting plate 10 is installed on the inner walls of both sides of the lifting frame 9. The through hole 11 is opened on the top surface of the connecting plate 10. The rotating cylinder 5 is located at the center of the inner cavity of the through hole 11. The bearing 12 is located in the inner cavity of the through hole 11. The outer side wall of the bearing 12 is connected and fixed to the inner side wall of the through hole 11. The periphery of the top surface of the rotating cylinder 5 passes through the bearing 12 and is connected to the inner side wall of the bearing 12. With the side wall connection fixed, when the mixing rod 6 mixes the coating and additives, the electric push rod 8 is activated, which drives the lifting frame 9 to perform longitudinal reciprocating motion, thereby driving the connecting plate 10 to perform longitudinal reciprocating motion. This causes the connecting plate 10 to drive the rotating cylinder 5 to perform longitudinal reciprocating motion around the rhomboid rod 4 via the bearing 12. This allows multiple mixing rods 6 to perform longitudinal reciprocating motion. Since the bearing 12 is provided between the connecting plate 10 and the rotating cylinder 5, the rotation of the rotating cylinder 5 will drive the inner ring of the bearing 12 to rotate. This allows the rotating cylinder 5 to still rotate via the rhomboid rod 4 while performing longitudinal reciprocating motion, so that multiple mixing rods 6 rotate while moving longitudinally. This uniformly mixes the coating in the reactor body 1, thereby improving the mixing effect of the coating and additives and reducing the impact on the coating quality.

[0030] One end of each of the multiple mixing rods 6 is connected to a rubber spatula 13 for cleaning the paint residue on the inner wall of the reactor body 1. One side of each rubber spatula 13 is in contact with the inner wall of the reactor body 1, so that when the multiple mixing rods 6 rotate, they will drive the rubber spatula 13 to engage with the inner wall of the reactor body 1 and rotate, thus allowing the rubber spatula 13 to remove the paint residue left on the inner wall of the reactor body 1, making cleaning convenient.

[0031] Working principle:

[0032] This chemical reaction vessel for coating preparation involves adding the coating and additives to be mixed into the reaction vessel body 1. Then, the drive motor 3 is turned on, which drives the rotating drum 5 via the rhomboid rod 4, thereby rotating multiple mixing rods 6 to mix the coating and additives. Then, the electric push rod 8 is turned on, which drives the lifting frame 9 to reciprocate longitudinally. This, in turn, drives the rotating drum 5 to reciprocate longitudinally around the rhomboid rod 4 via the connecting plate 10, allowing the multiple mixing rods 6 to reciprocate longitudinally. Because a bearing 12 is provided between the connecting plate 10 and the rotating drum 5, the rotating drum 5 continues to rotate via the rhomboid rod 4 during its longitudinal reciprocating motion, allowing the multiple mixing rods 6 to rotate simultaneously with their longitudinal movement. This ensures uniform mixing of the coating and additives within the reaction vessel body 1, improving the mixing effect of the coating and additives and reducing the impact on coating quality.
