Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a water-based paint batching device. Background Art

[0002] Any coating that uses water as a solvent or dispersion medium can be called a water-based coating. Water-based coatings include three types: water-soluble coatings, water-dilutable coatings, and water-dispersible coatings (latex coatings). Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products. In addition, there are water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins.

[0003] The essence of coatings with different properties and different uses lies in their different composition. For example, epoxy resin, acrylic resin, polyurethane resin, pure acrylic emulsion, hydroxyethyl acrylate copolymer, water-based acrylic resin, water-based polyurethane resin, water-based epoxy resin, etc. Different water-based coatings can be obtained by mixing various raw materials in different types and proportions.

[0004] The batching process of water-based paint is a mixing process of multiple raw materials. Different raw materials are often mixed into the final paint product by stirring and mixing. Water-based paint has very high requirements for uniform mixing. If it is not mixed evenly, the final sprayed paint surface will have very obvious errors. The traditional stirring setting usually improves the mixing efficiency by extending the stirring and mixing time, but this still cannot ensure that the raw materials are mixed evenly, and the mixing process is also very time-consuming. If the raw materials of the paint contain a small amount of solid powder, then the inefficient mixing equipment is also prone to cause solid powder agglomeration. Utility Model Content

[0025] Example

[0026] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 3 As shown, the water-based paint dispensing equipment of this embodiment is characterized by: comprising a mixing tank 11, a plurality of feeding devices arranged above the mixing tank 11, a feeding pipe 16 arranged inside the mixing tank 11 and sealed at the lower end, a plurality of feeding ports 17 opened on the side wall of the lower end of the feeding pipe 16, and a stirring device arranged in the mixing tank 11; the feeding device comprises a feeding tank 12, a feeding pipe 13 arranged at the upper end of the feeding tank 12, a conduit 15 arranged at the lower end of the feeding tank 12, and a pressurizing device connected to the feeding tank 12; the plurality of conduits 15 are all connected to the feeding pipe 16. Specifically, when in use, the raw materials are added to the feeding tank 12 through the feeding pipe 13, and then the feeding tank 12 is pressurized by a pressure device, and the raw materials in multiple feeding tanks 12 are pumped into the feeding pipe 16 at the same time, so that the raw materials are sprayed into the mixing tank 11 through the feeding port 17 after completing preliminary mixing in the feeding pipe 16, and then the final mixing is performed by the stirring device in the mixing tank 11. In this process, the pumping rate of the materials can be controlled by controlling the pressure of the pressure device on the feeding tank 12, so that all the materials are added at the same time, which can significantly speed up the mixing efficiency of various materials, not only improve the dispersibility after mixing, but also significantly reduce the mixing time and improve production efficiency.

[0027] The mixing tank 11 in this embodiment is connected with a negative pressure device. By pumping negative pressure on the mixing tank 11 through the negative pressure machine and the negative pressure pipe 113, the efficiency of the raw materials entering the mixing tank 11 can be improved.

[0028] In this embodiment, a spiral plate 18 is provided inside the feed pipe 16. Specifically, the spiral plate 18 can cause the material to generate a spiral flow in the feed pipe 16, so that the material can be better mixed.

[0029] The mixing tank 11 in this embodiment is provided with a powder box inside, and a plurality of feeding holes 110 are provided on the lower end wall of the powder box, and a powder pipe 111 is connected to the powder box. A vibration motor 112 is connected to the powder box. The powder box is arranged above the feed port 17. Specifically, the powder box is used to add solid materials (mainly powders), and the powder box is continuously shaken by the vibration motor 112, so that the materials in the powder box can be evenly sprinkled into the mixing tank 11, and the liquid raw material is also sprayed out from the feeding pipe 13 at this time, so that the powder material can be more fully and evenly dispersed in the liquid material, and agglomeration can be effectively avoided.

[0030] The stirring device in this embodiment includes a stirring blade 21 disposed at the lower part of the mixing tank 11 and a driving motor 22 for driving the stirring blade 21 to rotate.

[0031] The pressurizing device in this embodiment includes an air pipe 14 connected to the feeding tank 12, and an air compressor connected to the air pipe 14. Specifically, the pressurizing device can not only pressurize the feeding tank 12 through the air pipe 14, but also extract the gas in the feeding tank 12 to form a negative pressure, which is more conducive to the raw material entering through the feeding pipe 13. At this time, an automatic valve needs to be set on the conduit 15.

[0032] In summary, the water-based paint batching equipment in this embodiment, when in use, adds the raw materials into the feeding tank 12 through the feeding pipe 13, and then uses a pressure device to pressurize the feeding tank 12, and at the same time pumps the raw materials in multiple feeding tanks 12 into the feeding pipe 16, so that the raw materials are sprayed into the mixing tank 11 through the feeding port 17 after completing preliminary mixing in the feeding pipe 16, and then the final mixing is performed by the stirring device in the mixing tank 11. In this process, the pumping rate of the material can be controlled by controlling the pressure of the pressure device on the feeding tank 12, so that all the materials are added at the same time, which can significantly speed up the mixing efficiency of various materials, not only can improve the dispersibility after mixing, but also can significantly reduce the mixing time and improve production efficiency.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
