Description

Technical Field

[0001] This utility model belongs to the field of coating production technology, and in particular relates to an energy-saving reaction vessel for coating production. Background Technology

[0002] Applying paint to the surface of an object creates an effective barrier, preventing the object from being exposed to the natural environment and thus protecting it, increasing its applicability in various environments. Paint also provides rich decoration, greatly enhancing and altering the appearance of objects. These characteristics have led to the frequent use of paint in daily processing, promoting the development of the paint industry. To meet market demand, large-scale paint production and processing are necessary. The paint processing requires the use of reaction vessels, which consist of a vessel body, stirring device, jacket structure, and internal coils.

[0003] A search revealed a reaction vessel for paint production in patent document CN 223082785 U, comprising a base, a vessel body mounted on the upper end of the base, a sealing mechanism at the upper end of the vessel body, and a working mechanism. A long-shaft motor with a stirring rack mounted on its output end drives the stirring rack to rotate, enabling the mixing reaction of water-based paints. When processing another type of water-based paint, two lifting pipe supports are slidably connected to the rotating frame, lifting the two lifting pipe supports upwards to detach the stirring rack from the vessel body. Simultaneously, the limiting structure is adjusted to prevent it from limiting the sleeve. Then, the rotating frame is rotated to swap the positions of the stirring rack and the cleaning rack. When no force is applied to the handles between the two lifting pipe supports, the cleaning rack falls into the vessel body. By activating the long-shaft motor with the cleaning rack fixed at its input end, the cleaning rack scrapes off the paint adhering to the inner wall of the vessel. Simultaneously, because the stirring rack is located outside the vessel body, it is convenient to clean the stirring rack.

[0004] However, existing reaction vessels used in paint production still have the following shortcomings in actual use: 1. First, the top surface of the vessel body is abutted by a top cover. The top surface of the top cover is connected to a ring array of fastening bolts. The lower end of the fastening bolts is threaded to the top cover. The top end of the top cover has a feed port. The upper end of the feed port is threaded to a sealing cap. The sealing cap is removed by rotating it counterclockwise. The raw materials of the coating are introduced into the vessel body through the feed port. The stirring mechanism is started to stir and mix the raw materials of the coating inside the vessel body. However, the raw materials of the coating enter the vessel body in a concentrated manner through the feed port, which will cause the raw materials of the coating to concentrate on one side of the vessel body, making it inconvenient to mix and stir. It is necessary to extend the stirring time and increase the demand for electricity. 2. Secondly, when processing another type of water-based coating, the two lifting tube frames are slidably connected to the rotating frame. By grasping the handle structure between the two lifting tube frames and lifting them, the stirring frame is detached from the vessel body. At the same time, the limiting structure is adjusted so that it does not limit the sleeve. Then, rotating the rotating frame allows the positions of the stirring frame and the cleaning frame to be swapped. When no external force is applied to the handle structure between the two lifting tube frames, the cleaning frame can fall into the vessel body. By starting the long shaft motor with the cleaning frame fixed at the input end, the cleaning frame can scrape off the coating adhering to the inner wall of the vessel. At the same time, since the stirring frame is located outside the vessel body, it is convenient to clean the stirring frame. However, when cleaning the coating residue on the inner wall of the vessel body, the operation steps are cumbersome, the cleaning time is extended, the downtime is increased, and the production efficiency of the coating is reduced.

[0005] To address these issues, we provide an energy-saving reactor for paint production. Utility Model Content

[0006] The purpose of this utility model is to provide an energy-saving reactor for coating production. By setting up a feeding component, the raw materials of the coating are dispersed into the interior of the reactor, which facilitates rapid and uniform mixing, reduces mixing time, and reduces power consumption. Furthermore, by setting up a cleaning component, the steps of cleaning residual coating inside the reactor are simplified, reducing workload, shortening cleaning time, and reducing downtime, which helps to accelerate the production efficiency of coatings, thereby solving the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an energy-saving reaction vessel for coating production, comprising a vessel body, a feeding assembly on the upper surface of the vessel body, the feeding assembly including a vessel cover abutting against the vessel body, a hopper being fixedly connected to the upper end of a main pipe rotatably connected to the upper surface of the vessel cover, and branch pipes being fixedly connected to the lower periphery of the main pipe in a ring array; a cleaning assembly is provided at the lower end of the main pipe, the cleaning assembly including a stirring shaft installed at the lower end of the main pipe, a scraper mounted at the lower end of the stirring shaft abutting against the inner wall of the vessel body, and a stirring rod installed on the side wall of the stirring shaft connected to the inner wall of the scraper.

[0008] The present invention is further configured such that a collar seat is fixedly connected to the lower edge of the outer periphery of the vessel body, and a support foot is installed in a ring array on the lower surface of the collar seat. A valve is installed on the discharge pipe that is connected and fixed to the lower surface of the vessel body.

[0009] The present invention is further configured such that the support leg is an L-shaped structure, and a reinforcing plate is obliquely fixed to the support leg.

[0010] The present invention is further configured such that a lower sleeve plate is fixedly connected to the upper edge of the outer periphery of the vessel body, an upper sleeve plate fixedly connected to the lower edge of the outer periphery of the vessel cover abuts against the lower sleeve plate, and bolts are connected to the upper surface of the upper sleeve plate in an annular array of threads, with the lower end of the bolts threadedly connected to the lower sleeve plate.

[0011] The present invention is further configured such that the upper surface of the kettle lid is connected to an air outlet pipe and a water inlet pipe, an actuated valve is installed on the air outlet pipe, and a valve is installed on the water inlet pipe.

[0012] The present invention is further configured such that a motor is provided on the lid of the vessel, the output end of the motor is connected to a rotating shaft, a driving gear is fixedly connected to the circumference of the rotating shaft, and a driven gear that is meshed with the driving gear on the side is fixedly connected to the circumference of the main pipe.

[0013] The present invention is further configured such that a protective box is installed on the lid of the vessel, a cover is installed on the upper surface of the protective box, and the rotating shaft and the main pipe are rotatably connected to the cover.

[0014] The present invention is further configured such that a spiral impeller is installed at the lower end of the stirring shaft, and the spiral impeller is disposed inside the discharge pipe.

[0015] This utility model has the following beneficial effects: 1. This utility model, through the installation of a feeding assembly, allows the motor to drive a drive gear via a rotating shaft after being powered on. This drive gear, along with the driven gear and the connected main pipe, hopper, and branch pipes, rotate together. The coating raw materials are added from the hopper, distributed through the main pipe to the branch pipes, and finally dispersed and sprinkled into the reactor. This feeding method effectively avoids localized accumulation of raw materials within the reactor, facilitating rapid and uniform mixing, thereby shortening mixing time, reducing motor energy consumption, and achieving energy savings. 2. This utility model incorporates a cleaning component. When the main pipe rotates, it drives the stirring shaft, stirring rod, and scraper to rotate, uniformly mixing the paint raw materials and water inside the vessel, thus accelerating the mixing efficiency. When it is necessary to discharge the paint from the vessel, the rotating stirring shaft drives the spiral impeller to rotate, pushing the paint inside the vessel downwards for discharge, making the discharge of paint from the vessel more rapid. When it is necessary to clean the paint residue on the inner wall of the vessel, cleaning water is introduced into the hopper. The cleaning water falls into the vessel through the main pipe and branch pipes, rinsing the vessel and the cleaning component. At the same time, the rotating scraper cleans the paint residue on the inner wall of the vessel, simplifying the steps of cleaning the paint residue on the inner wall of the vessel, reducing cleaning time, reducing downtime, and helping to accelerate the production efficiency of paint.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0018] Please see Figure 1 and Figure 2 This utility model is an energy-saving reaction vessel for paint production, including a vessel body 1, a discharge pipe 104 and a valve 105. When the valve 105 on the discharge pipe 104 is opened, the paint inside the vessel body 1 is discharged through the discharge pipe 104. Specifically, a collar seat 101 is fixedly connected to the lower edge of the outer periphery of the vessel body 1, and a support leg 102 is installed in a ring array on the lower surface of the collar seat 101. A valve 105a is installed on the discharge pipe 104 that is connected and fixed to the lower surface of the vessel body 1. Furthermore, the support leg 102 has an L-shaped structure, and a reinforcing plate 103 is fixedly attached to the support leg 102 at an angle. The support leg 102 creates a gap between the lower surface of the vessel body 1 and the ground, which facilitates the discharge of the coating inside the vessel body 1. The reinforcing plate 103 strengthens the support leg 102 and supports the vessel body 1 more stably. The operation process of this embodiment is as follows: After the production of the coating is completed inside the vessel 1, the operator opens the valve 105a on the discharge pipe 104 to remove the obstruction to the coating inside the vessel 1, allowing the coating inside the vessel 1 to be discharged into the discharge pipe 104 by automatic weight; conversely, the operator closes the valve 105a on the discharge pipe 104 to seal the outlet of the discharge pipe 104 and prevent the coating inside the vessel 1 from being discharged. Example 2

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on the first specific embodiment, a feeding component 2 is provided. The feeding component 2 includes a lid 201, a main pipe 204, a hopper 204a, and branch pipes 204b. The coating material inside the hopper 204a enters the main pipe 204. Since the main pipe 204 has a ring array of branch pipes 204b, the coating material inside the main pipe 204 is dispersed into the vessel body 1 through multiple branch pipes 204b, which avoids the coating material inside the vessel body 1 being too concentrated, facilitates quick and even mixing, shortens the mixing time, reduces the running time of the motor 208, thereby reducing the demand for electricity and achieving the purpose of saving electricity. Specifically, the lid 201 abuts against the body 1, and the upper end of the main pipe 204 rotatably connected to the upper surface of the lid 201 is connected to and fixedly connected to the hopper 204a. The lower edge of the main pipe 204 is connected to and fixedly connected to the branch pipe 204b in a ring array. Furthermore, a lower sleeve plate 106 is fixedly connected to the upper edge of the outer periphery of the vessel body 1, and an upper sleeve plate 201a fixedly connected to the lower edge of the outer periphery of the vessel cover 201 abuts against the lower sleeve plate 106. Bolts 205 are connected to the upper surface of the upper sleeve plate 201a via a ring-shaped array of threads, and the lower ends of the bolts 205 are threaded onto the lower sleeve plate 106. An air outlet pipe 202 and a water inlet pipe 203 are connected to the upper surface of the vessel cover 201. A pneumatic valve 202a is installed on the air outlet pipe 202, and a pneumatic valve 202a is installed on the water inlet pipe 203. There is a valve 105a. A motor 208 is installed on the lid 201. The output end of the motor 208 is connected to a rotating shaft 208a. A drive gear 206 is fixed to the circumference of the rotating shaft 208a. A driven gear 206a, which is meshed with the drive gear 206, is fixed to the circumference of the main pipe 204. A protective box 207 is installed on the lid 201. A cover 207a is installed on the upper surface of the protective box 207. The rotating shaft 208a and the main pipe 204 are rotatably connected to the cover 207a. The operation process of this embodiment is as follows: The motor 208 is energized, driving the rotating shaft 208a to rotate, causing the drive gear 206 to rotate, which in turn drives the driven gear 206a to rotate, thereby causing the main pipe 204 to rotate. The hopper 204a rotates accordingly, simultaneously driving the branch pipes 204b to rotate, guiding the coating material into the hopper 204a. The coating material inside the hopper 204a flows downwards into the main pipe 204 due to its own weight. The coating material in the main pipe 204 passes through multiple branch pipes 204b, which are rotating, causing the coating material to fall into the vessel 1 in a dispersed manner, preventing the coating material from becoming too concentrated. The valve on the water inlet pipe 203 is then opened. 105. Water is introduced into the water inlet pipe 203. The water inside the water inlet pipe 203 falls into the vessel body 1 by its own weight, so that the paint raw materials are mixed with the water. When it is necessary to remove the vessel cover 201, the operator uses a wrench to rotate the bolt 205 counterclockwise. The bolt 205 rotates counterclockwise and moves upward until the bolt 205 is disengaged from the lower sleeve plate 106, thus releasing the fixation of the vessel cover 201. The vessel cover 201 is then pulled upward to remove it. Conversely, the operator places the vessel cover 201 against the vessel body 1 and uses a wrench to rotate the bolt 205 clockwise until the bolt 205 is threadedly connected to the lower sleeve plate 106, thus fixing the position of the vessel cover 201 on the vessel body 1. Example 3

[0020] Please see Figure 2 Based on specific embodiments one and two, a cleaning component 3 is provided. The cleaning component 3 includes a scraper 301, a stirring rod 302 and a stirring shaft 303. The main pipe 204 rotates, causing the stirring rod 302 and the stirring shaft 303 to stir and mix the paint raw materials and water in the mixing vessel 1, thereby accelerating the mixing efficiency. At the same time, the scraper 301 rotates to clean the paint on the inner wall of the vessel 1, thereby reducing the amount of paint residue on the inner wall of the vessel 1. Specifically, the stirring shaft 303 is installed at the lower end of the main pipe 204, and the scraper 301 installed at the lower end of the stirring shaft 303 abuts against the inner wall of the vessel body 1. The stirring rod 302 installed on the side wall of the stirring shaft 303 is connected to the inner wall of the scraper 301. Furthermore, a spiral impeller 304 is installed at the lower end of the stirring shaft 303, and the spiral impeller 304 is located inside the discharge pipe 104; The operation process of this embodiment is as follows: The motor 208 is energized, causing the main pipe 204 to rotate, which in turn drives the stirring shaft 303 to rotate, stirring the paint raw materials and water inside the vessel 1. Simultaneously, the rotating stirring shaft 303 drives the stirring rod 302 to rotate, further stirring the paint raw materials and water inside the vessel 1. The scraper 301 also rotates with the stirring shaft 303, cleaning the paint on the inner wall of the vessel 1 and reducing paint residue inside the vessel 1. When it is necessary to discharge the paint from inside the vessel 1, the valve 105 on the discharge pipe 104 is opened. The rotating stirring shaft 303 drives the spiral impeller 304 to rotate, drawing the paint from inside the vessel 1 into the discharge pipe 104. At the same time, the discharge pipe 104 is pushed... 4. The coating inside moves downward and is discharged, allowing the coating to be fed by its own weight and the cooperation of the rotating spiral impeller 304. When it is necessary to clean the coating residue on the inner wall of the vessel 1, cleaning water is introduced into the hopper 204a. The cleaning water enters the main pipe 204 by its own weight. The water in the main pipe 204 enters the vessel 1 through multiple branch pipes 204b. At the same time, the rotating stirring shaft 303 drives the scraper 301 to rotate, cleaning the coating residue on the vessel 1. Meanwhile, the cleaning water rinses and cleans the cleaning component 3. During the feeding and mixing process, the scraper 301 rotates with the shaft, assisting in bringing the raw material on the wall into the main mixing area. During the cleaning process, the scraper 301 closely adheres to the inner wall to achieve thorough scraping.
