Description

Technical Field

[0001] This utility model relates to the field of coating production technology, specifically to a processing reaction device for water-based coatings. Background Technology

[0002] Water-based coatings typically require thorough mixing of materials such as deionized water, water-based resin, thickener, dispersant, defoamer, and film-forming aids before preparation. If impurities in the raw materials are not filtered out during the preparation process, the coating may not mix well, resulting in uneven coating particles and affecting its quality.

[0003] Because various solid raw materials are involved, uneven particle size is prone to occur, leading to insufficient mixing of solid raw materials. When solid raw materials with excessively large particle sizes are mixed with solvents, they fail to fully integrate, resulting in poor coating mixing effect. Existing water-based coating processing reactors do not have a structure to control the particle size of solid raw materials, and the problem of excessively large particles in solid raw materials has not been solved, resulting in poor coating mixing effect produced by water-based coating processing reactors.

Detailed Implementation

[0024] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples:

[0025] This utility model discloses a processing reaction device for water-based coatings, such as... Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, the reaction device includes a base 1 and a base 2. The base 2 is fixedly connected above the base 1. The top of the base 2 is provided with a feed inlet 3, and a screen 31 is inserted into the feed inlet 3. A first mixing mechanism 4 is provided in the base 2 below the feed inlet 3. A second mixing mechanism 6 is provided in the base 2 below the first mixing mechanism 4 and connected to the first mixing mechanism 4 via a transmission pipe 5. Both the first mixing mechanism 4 and the second mixing mechanism 6 are connected to a drive mechanism 7 to obtain power. The drive mechanism 7 includes a first power source 71. A stirring tank 8 with a temperature control device 81 is provided in the base 2 below the second mixing mechanism 6. A stirring mechanism 84 is provided in the stirring tank 8. Several conveying pipes 82 extending to the outside of the base 2 are provided on one side of the top of the stirring tank 8. A discharge port 83 is provided on the side wall of the stirring tank 8. A control box 9 is provided in the space inside the base 1. The control box 9 is electrically connected to the drive mechanism 7, the stirring mechanism 84 and the temperature control device 81 respectively.

[0026] It should be noted that: the raw materials for the coating enter through the feed inlet 3. When passing through the screen 31, the mesh on the screen 31 will initially remove particles with excessive diameter in the raw materials; then the raw materials enter the first mixing mechanism 4, where the first mixing mechanism 4 stirs and mixes the raw materials. The mixed coating raw materials are then transferred to the second mixing mechanism 6 through the transmission pipe 5; the second mixing mechanism 6 further mixes the raw materials and then transfers them to the mixing tank 8. At the same time, the conveying pipe 82 transfers the solvent of the coating to the mixing tank 8, where the reaction takes place under the stirring of the stirring mechanism 84 and the cooperation of the temperature control device 81, thereby forming the final water-based coating; the processed coating can be discharged out of the mixing tank 8 through the discharge port 83, and the operation of the drive mechanism 7, the stirring mechanism 84, and the temperature control device 81 in the reaction device can be controlled by the control box 9.

[0027] The screen 31 in the reaction device can initially separate large particles of raw materials. The coating raw materials processed by the first mixing mechanism 4 and the second mixing mechanism 6 are fully mixed and the particle size is uniform. The raw materials are then transferred to the stirring tank 8 and mixed with the solvent under the stirring action of the stirring mechanism 84, thereby ensuring the quality of the coating obtained after the reaction in the stirring tank 8 and automatically completing the entire water-based coating production process.

[0028] It needs to be further explained that, such as Figure 4 and Figure 5 As shown, the first mixing mechanism 4 includes a mixing cylinder 41 and a first stirring paddle 42. A first fixed seat 43 is provided in the base 2 below the feed inlet 3. Both ends of the mixing cylinder 41 in the axial direction are provided with first mating parts 411. The mating parts at both ends of the mixing cylinder 41 are respectively mated in the first mating holes 431 at both ends of the first fixed seat 43. The bottom end of the feed inlet 3 is connected to the mixing cylinder 41. Both ends of the first stirring paddle 42 in the axial direction are provided with second mating parts 421. The first mating parts 411 are provided with second mating holes 4111. The first stirring paddle 42 is connected to the mixing cylinder 41 through the mating of the second mating parts 421 and the second mating holes 4111. One of the second mating parts 421 of the first stirring paddle 42 is connected to the drive mechanism 7. Both ends of the mixing cylinder 41 are connected to transmission pipes 5.

[0029] Driven by the drive mechanism 7, the first stirring paddle 42 stirs the water-based coating raw material that enters the mixing cylinder 41 from the feed inlet 3, so that the raw material is fully mixed. In addition, the first stirring paddle 42 guides the raw material during the stirring process, causing the raw material to move to one of the axial ends of the mixing cylinder 41, so that the raw material enters any one of the transmission pipes 5, so as to achieve the purpose of moving the mixed raw material to the second mixing mechanism 6.

[0030] Specifically, such as Figure 5 As shown, the drive mechanism 7 also includes a first drive wheel 72 and a first drive belt 73. The output end of the first power source 71 and one of the second mating parts 421 of the first stirring paddle 42 are provided with the first drive wheel 72, and the two first drive wheels 72 are connected by the first drive belt 73.

[0031] In this system, the control box 9 controls the start of the first power source 71. The first transmission wheel 72 connected to the output end of the first power source 71 rotates under the drive of the first power source 71 and transmits power to the first transmission wheel 72 on the first stirring paddle 42 through the first transmission belt 73, thereby causing the first stirring paddle 42 to rotate. In turn, the first stirring paddle 42 stirs the water-based coating raw materials in the mixing cylinder 41. The structure of the drive mechanism 7 transmitting power to the first mixing mechanism 4 is simple.

[0032] It needs to be further explained that, such as Figure 1 , Figure 6 and Figure 7 As shown, the second mixing mechanism 6 includes a housing 61 and a roller 62. The bottom end of the housing 61 is fixed inside the base 2 below the first mixing mechanism 4. Both ends of the housing 61 are provided with third mating holes 611. Both ends of the roller 62 are provided with third mating parts 621. The roller 62 is mated to the housing 61 through the connection between the third mating parts 621 and the third mating holes 611. One of the third mating parts 621 extends through to the outside of the third mating hole 611 and is connected to the drive mechanism 7. The middle part of the third mating part 621 is provided with a fourth mating hole 6211. The bottom end of the transmission pipe 5 extends through the fourth mating hole 6211 into the roller 62. The side wall of the roller 62 is provided with several through holes 63.

[0033] After being processed by the first mixing mechanism 4, the raw materials enter the drum 62 through the transmission pipe 5. The drum 62 rotates under the drive mechanism 7, and the raw materials tumble inside the drum 62 for further mixing. The raw materials with particle sizes that can pass through the through hole 63 will enter the shell 61 and then be transferred from the shell 61 to the mixing tank 8. The raw materials with particle sizes that cannot pass through the through hole 63 will continuously impact the inner wall of the drum 62, thereby dispersing the raw materials with excessively large particle sizes through impact, forming them into a size that can pass through the through hole 63. Even if the size of the raw material particles does not change, these raw material particles that do not meet the size requirements can be further screened out to prevent them from entering the mixing tank 8.

[0034] Specifically, such as Figure 6 and Figure 7As shown, the drive mechanism 7 further includes a second drive wheel 74, a second drive belt 75, and a third drive wheel 76. The output end of the first power source 71 is provided with the second drive wheel 74. The third drive wheel 76 is provided in the base 2 outside the housing 61 through a rotating shaft. The second drive wheel 74 and the third drive wheel 76 are connected by the second drive belt 75. A fourth drive wheel 77 that fits into the third mating part 621 is fitted on the rotating shaft outside the third drive wheel 76.

[0035] In this system, the control box 9 controls the start of the first power source 71, and the second transmission wheel 74 on the output end of the first power source 71 rotates. It then transmits power to the rotating shaft through the second transmission belt 75 and the third transmission wheel 76, causing the rotating shaft to rotate. When the rotating shaft rotates, it drives the fourth transmission wheel 77 to rotate, and then transmits power to the third mating part 621 through the fourth transmission wheel 77, causing the third mating part 621 to rotate within the third mating hole 611, thereby causing the drum 62 to rotate. The structure of the drive mechanism 7 transmitting power to the second mixing mechanism 6 is simple.

[0036] It needs to be further explained that, such as Figure 8 As shown, the stirring mechanism 84 includes a second stirring paddle 85 and a second power source 86. The second power source 86 is disposed on the wall of the base 2 below the stirring tank 8. The second stirring paddle 85 is connected to the output end of the second power source 86 and extends into the stirring tank 8.

[0037] Among them, the control box 9 controls the second power source 86 to start, and the second power source 86 drives the second stirring paddle 85 to rotate, thereby stirring the coating raw materials and solvents in the stirring tank 8 to obtain water-based coatings. The stirring mechanism 84 has a simple structure.

[0038] It needs to be further explained that, such as Figure 3 and Figure 9 As shown, one end of the screen 31 is a handle 311, which extends to the outside of the side wall of the feed inlet 3.

[0039] The handle 311 allows people to easily remove the screen 31 from the feed inlet 3, preventing excessive raw material particles from accumulating on the screen 31 and promptly removing oversized raw material particles from the screen 31 to avoid affecting the transmission of raw materials.

[0040] It needs to be further explained that, such as Figure 8 As shown, the discharge port 83 is equipped with an electronic valve 87, which is electrically connected to the control box 9.

[0041] The control box 9 can control the opening and closing of the electronic valve 87, thereby controlling the opening and closing of the discharge port 83, and thus controlling the output of water-based coating in the mixing tank 8.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
