Description

Technical Field

[0001] The utility model relates to the technical field of industrial paint production, and particularly relates to a high-speed intermediate paint dispersion kettle. Background Art

[0002] Industrial paint is used for the protection and decoration of equipment, ships, containers, bridges, gas holders, port machinery, chemical equipment, railway tank cars, power machinery, storage tanks, inner walls of pipelines, various steel structures, concrete, etc. produced by industrial enterprises. When spraying equipment with industrial paint, it is divided into primer, intermediate paint and topcoat. Among them, the main function of the intermediate paint is to increase the film thickness of the paint. Since the paint coating as an anti-corrosion coating is not completely closed, increasing the thickness is an effective and low-cost means to enhance the anti-corrosion effect.

[0003] During the production process, various materials need to be mixed and stirred for pre-dispersion, stirring, high-speed dispersion, paint adjustment and color adjustment. These operations require the use of a dispersion kettle. The existing dispersion kettle is prone to paint stratification, resulting in uneven stirring. Moreover, during the dispersion and stirring process, as time goes by, the temperature of the dispersion kettle body also rises. The stirring temperature of the paint needs to be within a suitable range. If the temperature rises too high, it will affect the quality of the paint. Summary of the Utility Model

[0004] Based on the above description, the utility model provides a high-speed intermediate paint dispersion kettle to solve the disadvantages of poor mixing effect of existing mixing and stirring equipment and lack of cooling function.

[0005] The utility model is realized through the following technical solutions:

[0008] Furthermore, a driving ring is sleeved on the outer side wall of the reaction kettle. A driving tooth is arranged in a surrounding manner on the outer side of the driving ring. A driving motor is fixedly installed on the top surface of the base through a motor base. The output end of the driving motor is arranged downward and a gear is connected to the end. The gear meshes with the driving tooth on the outer wall of the driving ring.

[0009] Furthermore, both the inner walls of the cover plate and the reaction kettle are arranged in a hollow manner and are interconnected. Water injection holes are respectively arranged on the outer side walls at both ends of the stirring shaft. The water injection holes are interconnected with the internal spaces of the cover plate and the side wall of the reaction kettle.

[0010] Furthermore, a connecting member is further arranged at the bottom of the cover plate. The connecting member is a planetary gear.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0015] 1. The present application is improved based on the existing stirring and mixing equipment.

Detailed implementation manners

[0022] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to the relevant drawings. Embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of this application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] Combined with Figures 1-5 As shown, a high-speed intermediate paint dispersion kettle includes:

[0025] Base 1, which is a rectangular pedestal for supporting the stirring equipment to ensure its stability during operation;

[0026] Reactor 2, which is a stirring container for paint liquid. Workers stir the raw materials inside it at high speed to make them fully mixed into qualified paint liquid inside. There is a feed inlet 23 on its side wall, a protruding part 22 at the bottom, and a discharge port 24 on the outer side wall of the protruding part 22. There is a sealing cover on the feed inlet 23 to prevent the smell of paint from spreading everywhere during the stirring process. There is a valve on the discharge port 24 for quantitative discharge for sub-packaging;

[0027] Stirring shaft 3, which is vertically arranged inside the reactor 2 and accelerates the rapid mixing of the paint liquid raw materials inside the reactor 2 by rotating;

[0028] The cooling component 4 is arranged at the top of the reactor 2 and communicated with the stirring shaft 3, and absorbs the heat generated by the stirring shaft 3 during operation through a refrigerant, so as to ensure that the paint quality will not be affected by high temperature.

[0029] Specifically, in this embodiment, a mounting hole is provided at the center of the top surface of the base 1, and the reactor 2 is rotatably mounted in the mounting hole through a bearing, so that the lower half is located below the base 1, so that the reactor 2 can rotate flexibly on the base 1.

[0030] The top and bottom ends of its stirring shaft 3 are movably assembled with the inner top surface and inner bottom surface of the reactor 2 through ball bearings, and gaskets are used for sealing on both sides of the ball bearings. In addition, in order to further improve the coverage range of the stirring shaft 3, a stirring frame 31 should also be arranged on its outer side wall synchronously, so as to accelerate the accelerated mixing of the raw materials inside the reactor 2.

[0031] In the conventional stirring method, generally, a motor is directly arranged at the top or bottom of the reactor 2 to drive the stirring shaft 3 to rotate and stir. This stirring method has relatively general effects. In order to effectively improve the production efficiency of this embodiment, a planetary stirring structure is adopted in this embodiment.

[0032] That is, a connecting piece 25 is arranged inside the reactor 2, and the connecting piece 25 is a planetary gear. For example Figure 4 As shown, the sun gear in the planetary gear structure is directly sleeved on the stirring shaft 3 and fixedly connected, and the outer wall of the tooth ring of the planetary gear is directly fixedly connected with the inner wall of the reactor 2;

[0033] Based on the above planetary drive structure, a drive motor 11 is also arranged on the top surface of the base 1. The drive motor 11 is fixedly installed through a motor base, and its output end is arranged vertically downward. At the same time, a drive ring 21 is sleeved on the outer side wall of the reactor 2. The outer side of the drive ring 21 is provided with tooth blocks, and a gear is arranged on the output end of the drive motor 11 and meshes with the tooth blocks on the outer wall of the drive ring 21.

[0034] To sum up, when the drive motor 11 drives the entire reactor 2 to rotate, the reactor 2 can synchronously drive the stirring shaft 3 to rotate in the reverse direction through the planetary gear structure. Moreover, during this process, the stirring shaft 3 achieves a speed increase effect, and its transmission ratio remains between 0.25 and 0.67; this enables the reactor 2 and the stirring shaft 3 to stir simultaneously, greatly improving its mixing efficiency and accelerating the production speed of the intermediate paint.

[0035] During the actual use process, the high-speed stirring process will cause the paint liquid to heat up rapidly. In order to avoid the production quality being affected due to the paint liquid being mixed at high temperature, it should be cooled in this embodiment.

[0036] The cooling assembly 4 includes a connecting seat 41. A sealing cover plate 26 is also provided at the top of the reaction kettle 2. One of the connecting seats 41 is fixedly installed at the center of the top surface of the cover plate 26, and the other is at the center of the bottom surface of the protruding part 22 at the bottom. A ball bearing is provided inside the connecting seat 41, and a water delivery pipe 42 is inserted therein. The other ends of the two water delivery pipes 42 are both communicated with the same water storage tank 43, and a water pump 44 is also provided at the water outlet end of the water storage tank 43.

[0037] In the above structure, even if the reaction kettle 2 rotates rapidly, it will not affect the normal delivery of its water delivery pipe 42. Therefore, it can ensure that the cooling assembly 4 and the stirring structure operate synchronously.

[0038] In addition, the stirring shaft 3 and the stirring frame 31 provided on its side wall should both be hollow, so as to cooperate with the water delivery pipe 42 to convey the refrigerant, in order to cool the paint liquid in the middle. At the same time, a cavity should also be provided inside the side wall of the reaction kettle 2, and this cavity should be communicated with the internal space of the stirring shaft 3, for example Figure 3 as shown.

[0039] Water injection holes 32 are provided at both the upper and lower ends of the stirring shaft 3. There are several of these water injection holes 32 and they surround the outer wall of the stirring shaft 3 and are exactly inside the cover plate 26. Therefore, when the refrigerant is injected from the top through the water delivery pipe 42, part of the refrigerant directly flows through the inside of the stirring shaft 3 for delivery, and the other part quickly diffuses to the inside of the side wall of the reaction kettle 2 from the top water injection port towards the four sides, so that it can be cooled from both the side wall and the center simultaneously, greatly improving the cooling effect. After the cooling is completed, the refrigerant inside the side wall of the reaction kettle 2 can then re-converge into the inside of the stirring shaft 3 through the water injection holes 32 at the bottom and be recycled back into the water storage tank 43 through the water delivery pipe 42 at the bottom.

[0040] In the above process, the refrigerant is completely isolated from the internal paint liquid, so it can be reused. Moreover, the effect of cooling from the center and the outer wall simultaneously is more obvious and efficient compared with the existing cooling effect, and it can effectively ensure the production quality of the paint liquid while ensuring the production speed.

[0041] A temperature sensor 5, a PT1000 or PT1100 temperature sensor, should also be additionally arranged on the top of the cover plate 26, and a display should be equipped for it. Moreover, it can be remotely connected to the water pump 44 on the water storage tank 43 by using a Bluetooth module, and the delivery speed of the refrigerant can be controlled according to the internal temperature to achieve the effect of automatic temperature adjustment.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of the present invention.
