Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection coating material production, in particular to a static pressure kettle for preparing environmental protection coating materials. Background Technique

[0002] In the production process of environmental protection coatings, the static pressure kettle is a key device for dissolving and mixing environmental protection coatings. However, there are a series of problems in the existing static pressure kettle during the dissolution process of environmental protection coatings, which not only affect the dissolution effect of the coatings, but also further affect the production efficiency and product quality of the coatings.

[0003] There are some problems in the actual use of the existing static pressure kettle, especially during the dissolution process of environmental protection coating materials. The environmental protection coating materials are very easy to accumulate at the bottom of the kettle. Due to the self-weight pressure of the environmental protection coating materials, it is difficult for the environmental protection coating materials on the inner wall of the bottom of the kettle to come into full contact with water and dissolve. This results in a poor dissolution effect of the environmental protection coating materials, affecting the production efficiency and product quality of the environmental protection coating materials. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a static pressure kettle for preparing environmental protection coating materials.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A static pressure kettle for preparing environmental protection coating materials, including a kettle body, a steam generator and a servo motor. There is a feed inlet at the top of the kettle body. A water guide pipe runs through the top of the kettle body and is located on one side of the feed inlet. There is a liquid guide pipe at the bottom of the kettle body. The steam generator is fixedly connected to the side wall of the kettle body. An inlet pipe is connected to the bottom of the steam generator, and an outlet pipe is connected to the top of the steam generator. Both the inlet pipe and the outlet pipe are right-angle pipes. The ends of the inlet pipe and the outlet pipe far from the steam generator penetrate the side wall of the kettle body and extend into the interior of the kettle body. A filter mesh body is fixedly connected inside the kettle body. There is a movable roller inside the filter mesh body. The servo motor is fixedly connected to the front surface of the kettle body. The driving end of the servo motor is fixedly connected to a driving rod. The driving rod penetrates the front wall of the kettle body and the front wall of the filter mesh body. The driving rod eccentrically passes through the movable roller. The end of the driving rod far from the servo motor is rotatably connected to the inner rear wall of the filter mesh body. Connecting rods are fixedly connected to both the front and rear surfaces of the movable roller. The top ends of the connecting rods are fixedly connected to cleaning plates. The cleaning plates are located above the filter mesh body. The driving rod penetrates through the two connecting rods.

[0006] Preferably, the end of the inlet pipe far from the steam generator is located below the filter mesh body, and the end of the outlet pipe far from the steam generator is located above the filter mesh body.

[0007] Preferably, the cross-sectional view of the filter net body is semicircular, the top of the cleaning plate is an arc surface, and the top arc surface of the cleaning plate is adapted to the inner wall of the filter net body.

[0008] Preferably, the filter net body is located below the feed inlet, and the water guide pipe is located above the filter net body.

[0009] Preferably, the two connecting rods are in contact with the front and rear walls inside the filter net body near the outer surface of the kettle body respectively.

[0010] The utility model has the following beneficial effects:

[0011] 1. For the hydrostatic kettle for preparing environmental protection coating materials, the environmental protection coating materials in the kettle body are concentrated by the filter net body, which can ensure that only a small part of the environmental protection coating materials pass through the screening and fall on the inner bottom wall of the kettle body. This design enables the water introduced by the water guide pipe to contact the environmental protection coating materials more directly and effectively, thereby improving the dissolution efficiency. Due to the screening effect of the filter net body, the volume of the environmental protection coating material mass passing through is small, which means that the contact area between water and the environmental protection coating materials increases, further accelerating the dissolution process.

[0012] 2. For the hydrostatic kettle for preparing environmental protection coating materials, the movable roller driven by the servo motor can not only extrude the environmental protection coating materials in the filter net body, break up the environmental protection coating materials that have not passed through the screening, making them easier to pass through the screening, thus accelerating the screening process. By means of eccentric rotation, the movable roller can also ensure that the environmental protection coating materials are evenly extruded, avoiding problems caused by excessive or too small local pressure. The cleaning plate on the connecting rod can clean the inner wall of the filter net body to prevent the environmental protection coating materials from blocking the mesh holes of the filter net body. This function is crucial for ensuring the continuous and efficient operation of the equipment. At the same time, the cleaning plate can also break up the environmental protection coating materials that have not passed through the screening of the filter net body during the cleaning process, further improving the screening efficiency.

[0013] 3. For the hydrostatic kettle for preparing environmental protection coating materials, high-temperature and high-pressure steam is introduced into the kettle body through the inlet pipe of the steam generator, which can enable the environmental protection coating material solution on the inner bottom wall of the kettle body to be dissolved in a heating and pressurizing environment. This environment is conducive to the rapid dissolution and reaction of the environmental protection coating materials. The design of the outlet pipe enables the high-temperature and high-pressure steam to be recycled, which not only saves energy but also ensures the consistency and stability of the environment inside the kettle body, contributing to improving the dissolution effect of the environmental protection coating materials.

Specific implementation manner

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0018] As Figure 1-2 shown, the embodiment of the present invention provides a hydrostatic kettle for preparing environmentally friendly coating materials, including a kettle body 1, a steam generator 5 and a servo motor 13. A feed inlet 2 is provided at the top of the kettle body 1, and a water guide pipe 3 is connected through the top of the kettle body 1. The water guide pipe 3 is located on one side of the feed inlet 2. A liquid guide pipe 4 is provided at the bottom of the kettle body 1. The steam generator 5 is fixedly connected to the side wall of the kettle body 1. An inlet pipe 6 is connected to the bottom of the steam generator 5, and an outlet pipe 7 is connected to the top of the steam generator 5. Both the inlet pipe 6 and the outlet pipe 7 are right-angle pipes. The ends of the inlet pipe 6 and the outlet pipe 7 far from the steam generator 5 penetrate through the side wall of the kettle body 1 and extend into the interior of the kettle body 1. A filter net body 8 is fixedly connected inside the kettle body 1. A movable roller 9 is arranged inside the filter net body 8. The servo motor 13 is fixedly connected to the front surface of the kettle body 1. The driving end of the servo motor 13 is fixedly connected to a driving rod 10. The driving rod 10 penetrates through the front wall of the kettle body 1 and the front wall of the filter net body 8. The driving rod 10 eccentrically passes through the movable roller 9. The end of the driving rod 10 far from the servo motor 13 is rotatably connected to the inner rear wall of the filter net body 8. Connecting rods 11 are fixedly connected to both the front and rear surfaces of the movable roller 9. The top ends of the connecting rods 11 are fixedly connected to a cleaning plate 12. The cleaning plate 12 is located above the filter net body 8. The driving rod 10 penetrates through the two connecting rods 11.

[0019] The end of the inlet pipe 6 far from the steam generator 5 is located below the filter net body 8. This design ensures that the high-temperature and high-pressure steam can first contact the environmentally friendly coating material below the filter net body 8, thereby more directly heating and pressurizing the environmentally friendly coating material and improving its dissolution efficiency. The end of the outlet pipe 7 far from the steam generator 5 is located above the filter net body 8. In this way, when the steam circulates in the kettle body 1, it can take away the heat and the possible steam above the filter net body 8, ensuring uniform temperature distribution in the kettle body 1 and avoiding local overheating.

[0020] The cross-sectional view of the filter mesh body 8 is semi-circular. This design not only increases the filtration area but also facilitates the uniform distribution and screening of the environmentally friendly coating material. The top of the cleaning plate 12 is an arc surface, and this arc surface is adapted to the inner wall of the filter mesh body 8. This design enables the cleaning plate 12 to more effectively clean the inner wall of the filter mesh body 8, prevent the environmentally friendly coating material from clogging the mesh holes, and ensure the continuity and stability of the filtration effect.

[0021] The filter mesh body 8 is located below the feed inlet 2. In this way, the environmentally friendly coating material entering from the feed inlet 2 can directly fall on the filter mesh body 8, facilitating screening and dissolution. The water conduit 3 is located above the filter mesh body 8. This design enables the water introduced from the water conduit 3 to directly wash the environmentally friendly coating material on the filter mesh body 8, helping to accelerate the dissolution process.

[0022] The two connecting rods 11 are respectively in contact with the front and rear walls inside the filter mesh body 8 near the outer surface of the kettle body 1. This design ensures that when the connecting rods 11 drive the cleaning plate 12 and the movable roller 9, they can stably act on the filter mesh body 8, avoiding shaking or misalignment and ensuring the normal operation of the equipment.

[0023] Working principle: When using the static pressure kettle for preparing environmentally friendly coating materials, the environmentally friendly coating materials are introduced into the kettle body 1 through the feed port 2. The environmentally friendly coating materials will fall into the filter mesh body 8, and the movable roller 9 is located between the filter mesh body 8 and the feed port 2, so that the movable roller 9 can disperse the environmentally friendly coating materials into the filter mesh body 8. Then, the servo motor 13 can drive the driving rod 10 to drive the movable roller 9 to rotate, so that the movable roller 9 rotates to directly below the water guide pipe 3. Water can be injected into the kettle body 1 through the water guide pipe 3, and the movable roller 9 can also disperse the injected water, so that the water can fully contact the environmentally friendly coating materials. High-temperature and high-pressure steam in the steam generator 5 can be introduced into the kettle body 1 through the introduction pipe 6. The high-temperature and high-pressure steam can first contact the environmentally friendly coating materials below the filter mesh body 8, thereby heating and pressurizing the environmentally friendly coating materials more directly and improving their dissolution efficiency. The discharge pipe 7 can discharge the steam in the kettle body 1 to form a cycle. When the steam circulates in the kettle body 1, the discharge pipe 7 can take away the heat and the possible steam above the filter mesh body 8 to ensure uniform temperature distribution in the kettle body 1 and avoid local overheating. Since the environmentally friendly coating materials are received by the filter mesh body 8, the environmentally friendly coating materials in the kettle body 1 can be concentrated through the filter mesh body 8, ensuring that only a small part of the environmentally friendly coating materials pass through the screening and fall on the inner bottom wall of the kettle body 1. This design enables the water introduced by the water guide pipe 3 to contact the environmentally friendly coating materials more directly and effectively, thereby improving the dissolution efficiency. Due to the screening effect of the filter mesh body 8, the volume of the environmentally friendly coating material mass passing through is small, which means that the contact area between the water and the environmentally friendly coating materials increases, further accelerating the dissolution process. During the dissolution process of the environmentally friendly coating materials, the servo motor 13 drives the movable roller 9 to rotate eccentrically and the cleaning plate 12 to rotate circumferentially. The movable roller 9 can not only extrude the environmentally friendly coating materials in the filter mesh body 8, break up the environmentally friendly coating materials that have not passed through the screening, making them easier to pass through the screening, thus accelerating the screening process. By means of the eccentric rotation of the movable roller 9, the movable roller 9 can also ensure that the environmentally friendly coating materials are evenly extruded, avoiding problems caused by excessive or too small local pressure. During the circumferential rotation of the cleaning plate 12 on the connecting rod 11, the cleaning plate 12 contacts the inner wall of the filter mesh body 8, enabling the cleaning plate 12 to clean the inner wall of the filter mesh body 8 and prevent the environmentally friendly coating materials from blocking the mesh holes of the filter mesh body 8. This function is crucial for ensuring the continuous and efficient operation of the equipment. At the same time, the cleaning plate 12 can also break up the environmentally friendly coating materials that have not passed through the screening of the filter mesh body 8 during the cleaning process, further improving the screening efficiency. The environmentally friendly coating materials passing through the screening of the filter mesh body 8 are rapidly dissolved under the action of high-temperature and high-pressure steam, and the resulting environmentally friendly coating material solution is discharged from the kettle body 1 through the liquid guide pipe 4 on the kettle body 1.

[0024] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
