Description

Technical Field

[0001] This utility model relates to the technical field of coating production equipment, specifically to a vortex stirring device for the production of water-based environmentally friendly coatings. Background Technology

[0002] In today's society, with the increasing awareness of environmental protection, water-based environmentally friendly coatings have been widely used in many fields such as construction, furniture, and automobiles due to their advantages such as low volatile organic compound (VOC) emissions, environmental friendliness, and minimal harm to human health. However, in the production process of water-based environmentally friendly coatings, the mixing process is a crucial step, directly affecting the quality and performance of the coating. Traditional coating mixing equipment has some problems during the mixing process, such as insufficient mixing, leading to inconsistencies in the color, viscosity, and other performance indicators of the coating, affecting the coating's performance and quality stability. This is because the mixing blades of traditional mixing equipment are relatively simple in design, making it difficult to form effective vortices during mixing, resulting in insufficient mixing between the various components of the coating.

[0003] Meanwhile, some traditional mixing equipment has poor stability and is prone to shaking during operation. This not only damages the equipment itself and shortens its service life, but may also cause paint to spill during mixing, resulting in waste of raw materials and pollution of the production environment.

[0004] Furthermore, in terms of material feeding, some traditional equipment lacks effective pre-mixing functions, directly adding various raw materials into the mixing tank. This results in a prolonged period after the raw materials enter the mixing tank before reaching a uniform mixing state, reducing production efficiency. In addition, the lack of proper sealing measures at the feeding port makes it easy for dust and other impurities to mix into the raw materials, affecting the purity and quality of the coating.

[0005] In view of this, we propose a vortex mixing device for the production of water-based environmentally friendly coatings. Utility Model Content

[0028] A vortex mixing device for producing water-based environmentally friendly coatings includes a tank 1. An internal mixing mechanism is installed inside the tank 1. The internal mixing mechanism includes an internal mixing shaft 10 rotatably mounted inside the tank 1. Several internal mixing blades 11 are fixedly installed on the outer circumference of the internal mixing shaft 10. Several unevenly distributed guide points 13 are integrally formed on the outer wall of the internal mixing blades 11. These guide points 13 can change the flow direction of the fluid during mixing, forming a vortex and improving the mixing effect. A support leg 2 is fixedly installed on each side of the tank 1, and a first mixing motor 6 with an output shaft coaxially fixed to the internal mixing shaft 10 is installed on one of the support legs 2 to drive the internal mixing shaft 10 to rotate. A bottom support plate 4 is fixedly installed between the bottoms of the two support legs 2 to enhance the stability of the equipment. A discharge pipe is fixedly installed at the center of the bottom of the tank 1, and a first valve is installed on the discharge pipe to control the discharge of coatings. A feeding hopper 5 is installed on the top of the tank 1, and a pre-mixing mechanism is installed inside the feeding hopper 5 to perform preliminary mixing of the added raw materials.

[0029] As a preferred embodiment, each support leg 2 is welded and fixed with a diagonal brace 3 on both sides, and the bottom of the diagonal brace 3 is fixedly connected to the bottom support plate 4, which further improves the stability of the support leg 2 and prevents the equipment from shaking during operation.

[0030] As a preferred embodiment, the bottom support plate 4 includes a disc located in the middle and connecting plates integrally formed on both sides of the disc. The connecting plates are welded and fixed to the support legs 2. The disc is located directly below the discharge pipe and can play a certain role in bearing the load and preventing paint from dripping onto the ground.

[0031] As a preferred embodiment, the feeding hopper 5 includes a shell 50, a pre-stirring mechanism is installed inside the shell 50, a feeding port is provided on the top of the shell 50, and a flip cover 52 is hinged to the feeding port by a hinge 53. A handle 54 is fixedly installed on the top of the flip cover 52 to facilitate opening and closing the feeding port and reduce the entry of dust and other impurities into the feeding hopper 5.

[0032] As a preferred embodiment, the pre-stirring mechanism includes an outer stirring shaft 51 rotatably mounted on the top of the outer casing 50, with a plurality of outer stirring blades 57 fixedly connected to the outer circumference of the outer stirring shaft 51, and a second stirring motor 55 with an output shaft coaxially fixed to the outer stirring shaft 51 mounted on the top of the outer casing 50, which can perform preliminary stirring on the added raw materials, making the raw materials more uniform before entering the tank 1.

[0033] As a preferred embodiment, the bottom of the outer shell 50 is integrally formed with a conical hopper 56, and a feed pipe 58 is installed at the bottom of the conical hopper 56. A second valve 59 is installed on the feed pipe 58 to facilitate control of the speed and amount of raw materials entering the tank 1.

[0034] As a preferred embodiment, a drive shaft 12 is integrally formed on the inner stirring shaft 10, and the drive shaft 12 is fixed coaxially with the first stirring motor 6 to ensure effective power transmission.

[0035] As a preferred embodiment, both the first valve and the second valve 59 are solenoid valves, which can be electrically controlled to achieve automated operation and improve production efficiency.

[0036] In operation, the vortex mixing device for water-based environmentally friendly coating production of this utility model first opens the flap 52 of the feeding hopper 5, adds the raw material into the feeding hopper 5, and then closes the flap 52. The second mixing motor 55 is then started, driving the outer mixing shaft 51 and outer mixing blades 57 to rotate, performing preliminary mixing of the raw material. After mixing for a period of time, the second valve 59 is opened, allowing the raw material to enter the tank 1 through the discharge pipe 58. During this process, pre-mixing makes the raw material more uniform, reducing the burden on subsequent internal mixing and improving overall mixing efficiency. Simultaneously, the sealing design of the flap 52 of the feeding hopper 5 ensures the purity of the raw material.

[0037] Simultaneously, the first stirring motor 6 is started, driving the inner stirring shaft 10 and inner stirring blades 11 to rotate, stirring the coating around the inner stirring shaft 10. The guide points 13 on the inner stirring blades 11 will form vortices during the stirring process, making the coating more uniformly stirred. The vortices formed during the internal stirring process greatly improve the uniformity of the coating and enhance the production quality of the coating.

[0038] Once the coating is mixed, open the first valve to allow the coating to be discharged from tank 1 through the discharge pipe. Because the first valve is a solenoid valve, automated operation improves discharge efficiency and reduces human error.

[0039] Application Examples

[0040] Suppose a paint manufacturer needs to produce a batch of water-based environmentally friendly paint using the vortex mixing equipment of this invention. The operator first prepares all raw materials according to the formula ratio, opens the hopper lid, adds the raw materials sequentially, and then closes the lid. The second mixing motor is started, and the pre-mixing time is set to 5 minutes for initial mixing of the raw materials. After 5 minutes, the second valve is opened, allowing the raw materials to slowly flow into the tank. Simultaneously, the first mixing motor is started, and the mixing time is set to 30 minutes. During the mixing process, vortices are formed at the guide points on the inner mixing blades, ensuring thorough mixing of the paint. After 30 minutes, mixing is complete, and the first valve is opened to discharge the mixed paint into a storage container. Testing shows that the uniformity and quality of the produced paint meet the company's production standards. Moreover, due to the equipment's good stability and high mixing efficiency, this production process saves approximately 20% of the time compared to previously used equipment, while reducing the paint defect rate by approximately 15%.
