Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and more specifically, to a water-based coating feeding structure. Background Technology

[0002] In existing water-based coating feeding systems, stable coating delivery and uniformity are crucial to coating quality.

[0003] Based on the above, the inventors have discovered that traditional feeding structures typically employ non-thermal pipelines or simple insulation layers during use, making it impossible to regulate the coating temperature. Especially in low-temperature environments, water-soluble resins and additives in the coating are prone to precipitation and crystallization, increasing the resistance to coating feeding and even causing pipeline blockage. Furthermore, pigments and fillers in water-based coatings usually require uniform dispersion, but traditional water-based coating feeding structures typically rely on low-speed stirring paddles at the bottom of the tank, which cannot provide sufficient shear force to break up pigment agglomerates, leading to pigment flocculation and sedimentation, resulting in stratification and affecting coating quality. Therefore, in view of this, the inventors have researched and improved existing structures to provide a water-based coating feeding structure with greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a water-based coating feeding structure. It can utilize a turbine impeller, rod-type stirring blades, and a propeller impeller, along with a variable frequency motor, to achieve segmented speed control. This provides sufficient shear force to break up pigment agglomerates, preventing pigment flocculation and sedimentation that could lead to stratification. At the same time, a spiral copper pipe is added between the outer and inner tanks, through which circulating warm water is introduced, keeping the interior of the inner tank at a constant temperature and effectively preventing the coating from crystallizing due to temperature fluctuations.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A water-based coating feeding structure includes an outer tank and an inner tank fixed inside the outer tank. A temperature control chamber is provided between the outer tank and the inner tank. A spiral copper tube is fixedly installed in the temperature control chamber. A top cover is installed on the top of the outer tank. A discharge pipe is fixedly connected to the bottom of the inner tank. A support frame is fixedly connected to the inner side of the discharge pipe. A stirring shaft is rotatably connected between the top cover and the support frame via a bearing. A turbine impeller, a rod-type stirring blade, and a propeller impeller are fixedly installed sequentially from bottom to top on the outer circumference of the stirring shaft. Several baffles are fixedly connected to the inner side wall of the inner tank.

[0009] Furthermore, both ends of the spiral copper tube extend to the outside of the outer barrel and are respectively equipped with a water inlet and a water outlet.

[0010] Furthermore, a variable frequency motor is fixedly installed at the top center of the top cover, and the top end of the stirring shaft extends to the top of the top cover and is connected to the output end of the variable frequency motor via a coupling.

[0011] Furthermore, the top of the top cover is provided with a feeding port, and the bottom end of the discharge pipe extends to the bottom of the outer barrel.

[0012] Furthermore, the rod-type stirring blades are provided in multiple sets and are located between the turbine impeller and the propeller impeller.

[0013] Furthermore, a baffle plate is rotatably mounted inside the discharge pipe via a pin, and a stepper motor is installed at the bottom of the outer barrel. One end of the pin extends to the outside of the outer barrel and is connected to the output end of the stepper motor via a coupling.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) In this solution, a spiral copper pipe is added between the outer and inner barrels, and circulating warm water is introduced into the spiral copper pipe to keep the inner barrel at a constant temperature. This method can effectively prevent the coating from crystallizing due to temperature.

[0017] (2) In this scheme, by setting up a turbine impeller, a rod-type stirring blade and a propeller impeller, the turbine impeller at the bottom can prevent the paint from settling, the rod-type stirring blade in the middle can dissolve the paint agglomerates, and the propeller impeller at the top can eliminate air bubbles in the paint. With the cooperation of the stirring shaft and the variable frequency motor, the speed can be controlled in segments, providing sufficient shear force to break up pigment agglomerates and avoid pigment flocculation and settling, resulting in stratification.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0043] Example:

[0044] Please see Figures 1-4A water-based coating feeding structure includes an outer tank 1 and an inner tank 2 fixed inside the outer tank 1. A temperature control chamber 3 is provided between the outer tank 1 and the inner tank 2. A spiral copper tube 4 is fixedly installed in the temperature control chamber 3. A top cover 5 is installed on the top of the outer tank 1. A discharge pipe 6 is fixed and connected to the bottom of the inner tank 2. A support frame 7 is fixedly connected to the inner side of the discharge pipe 6. A stirring shaft 8 is rotatably connected between the top cover 5 and the support frame 7 through a bearing. A turbine impeller 9, a rod-type stirring blade 10, and a propeller impeller 11 are fixedly installed on the outer periphery of the stirring shaft 8 from bottom to top. Several baffles 12 are fixedly connected to the inner side wall of the inner tank 2. In use, the turbine impeller 9 at the bottom can prevent the coating from settling, the rod-type stirring blade 10 in the middle can dissolve the coating agglomerates, and the propeller impeller 11 at the top can eliminate air bubbles in the coating. In addition, the baffles 12 can reduce eddies and improve shear uniformity.

[0045] See Figure 2 Both ends of the spiral copper tube 4 extend to the outside of the outer tub 1 and are respectively equipped with a water inlet 13 and a water outlet 14. During use, warm water can be introduced into the spiral copper tube 4 through the water inlet 13 and the water outlet 14 and circulate, so that the inside of the inner tub 2 is kept at a constant temperature.

[0046] See Figure 3 A variable frequency motor 15 is fixedly installed at the top center of the top cover 5. The top end of the stirring shaft 8 extends to the top of the top cover 5 and is connected to the output end of the variable frequency motor 15 through a coupling. During use, the stirring shaft 8 and the variable frequency motor 15 work together to achieve segmented speed control, providing sufficient shear force to break up pigment agglomerates and avoid pigment flocculation and sedimentation, resulting in stratification.

[0047] See Figure 3 The top of the top cover 5 is provided with a feed port 16, and the bottom end of the discharge pipe 6 extends to the bottom of the outer barrel 1.

[0048] See Figure 3 Multiple sets of rod-type stirring blades 10 are provided and located between the turbine impeller 9 and the propeller impeller 11.

[0049] See Figure 3 Inside the discharge pipe 6, a baffle plate 18 is rotatably mounted via a pin 17. A stepper motor 19 is mounted at the bottom of the outer barrel 1. One end of the pin 17 extends to the outside of the outer barrel 1 and is connected to the output end of the stepper motor 19 via a coupling. In use, the stepper motor 19, under the action of the pin 17, drives the pin 17 to rotate the baffle plate 18, thereby opening and closing the discharge pipe 6 and controlling the loading and unloading of the coating.

[0050] In use: Warm water is introduced into the spiral copper pipe 4 through the water inlet 13 and water outlet 14 and circulated to keep the inner barrel 2 at a constant temperature. This effectively prevents the coating from crystallizing due to temperature. After the coating is placed in the inner barrel 2 through the feed port 16, the variable frequency motor 15 is started. Under the action of the stirring shaft 8, the turbine impeller 9, the rod stirring blade 10, and the propeller impeller 11 all rotate and stir the coating. The turbine impeller 9 at the bottom prevents the coating from settling, the rod stirring blade 10 in the middle breaks up coating agglomerates, and the propeller impeller 11 at the top eliminates air bubbles in the coating. The variable frequency drive of the variable frequency motor 15 enables segmented speed control, providing sufficient shear force to break up pigment agglomerates and prevent pigment flocculation and sedimentation that leads to stratification.
