Description

Technical Field

[0001] The utility model relates to the technical field of defoaming and dispersing paint, in particular to a swing-type defoaming and dispersing device for water-based architectural paint. Background Art

[0002] Any paint that uses water as a solvent or dispersion medium can be called a water-based paint. Water-based paint has excellent non-stickiness and durability. Water-based paint uses water as a solvent, saving a lot of resources. Water-based paint eliminates the risk of fire during construction and reduces air pollution. Water-based paint only uses a small amount of low-toxic alcohol ether organic solvents, which improves the working environment conditions.

[0003] During the production of water-based paint, a large number of bubbles may be generated inside the paint. These bubbles can be eliminated by defoaming agents. Existing water-based paints are generally defoamed by inserting a stirring rod into the reaction tank to ensure full contact between the defoaming agent and the paint. However, the traditional reaction tank is fixed and cannot be swung. If the stirring rod in the reaction tank is relied upon, the defoaming agent and the paint can only be stirred in a single direction, resulting in a lot of time required for defoaming and stirring, and low defoaming efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the utility model provides a swing-type water-based architectural paint defoaming and dispersing device, which can effectively solve the problems in the prior art.

DETAILED DESCRIPTION

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example: Refer to Figures 1 to 3 A swing-type water-based architectural paint defoaming and dispersion equipment includes a reaction tank 1, a swing component and a stirring component. The top of the reaction tank 1 is fixedly connected to a feed hopper 2, and a fixed seat 3 is installed at the bottom of the reaction tank 1. The bottom of the reaction tank 1 is fixedly connected to a lower hopper 10.

[0023] The swing assembly includes two rotating shafts 4 fixedly mounted on the front and rear sides of the reaction tank 1 respectively, and the outer walls of the two rotating shafts 4 are rotatably mounted with fixing frames 5, and the two fixing frames 5 are fixedly mounted on the top of the fixing seat 3. The outer wall of one of the rotating shafts 4 is fixedly sleeved with a swing frame 6, and a sliding hole 7 is opened on the surface of the swing frame 6. A crankshaft 8 is slidably connected in the sliding hole 7. The width of the sliding hole 7 is equal to the diameter of the crankshaft 8. A motor 9 for driving the crankshaft 8 is fixedly mounted on the inner wall of one of the fixing frames 5. When in use, the water-based paint and defoaming agent are first put into the reaction tank 1 through the feed hopper 2, and then the motor 9 is started to drive the crankshaft 8 to rotate. The circular motion of its curved section can make it slide up and down in the sliding hole 7, so as to move the swing frame 6 to drive the reaction tank 1 to swing back and forth through the rotating shaft 4, so that the defoaming agent and water-based paint in the reaction tank 1 can move back and forth, fully contact the defoaming agent and water-based paint, and improve the defoaming efficiency of the water-based paint.

[0024] The stirring assembly includes a first stirring shaft 11 rotatably mounted in the reaction tank 1 and extending outside the reaction tank 1. A first gear 12 is fixedly sleeved on the outer wall of one end of the first stirring shaft 11 located outside the reaction tank 1, and a plurality of first stirring blades 13 are fixedly connected to the outer wall of one end of the first stirring shaft 11 located inside the reaction tank 1. A second gear 14 is fixedly connected to the outer wall of one of the fixing frames 5, and the second gear 14 is engaged with the first gear 12. When the reaction tank 1 swings back and forth, the first gear 12 can roll back and forth on the second gear 14, so that the first stirring shaft 11 can also drive each first stirring blade 13 to stir the defoaming agent and the water-based paint reciprocatingly, so that the defoaming agent and the water-based paint are better and more fully contacted.

[0025] Furthermore, a second stirring shaft 15 is rotatably installed in the reaction tank 1, and a plurality of second stirring blades 17 are fixedly connected to the outer wall of the second stirring shaft 15, and the outer walls of the second stirring shaft 15 and the first stirring shaft 11 are fixedly sleeved with a third gear 16, and the two third gears 16 are engaged with each other. When the first stirring shaft 11 rotates back and forth, the second stirring shaft 15 can drive each second stirring blade 17 to swing back and forth through the mutual engagement between the two third gears 16, and the second stirring blade 17 rotates in the opposite direction to the first stirring blade 13, further fully stirring and contacting the defoaming agent and the water-based paint, thereby further improving the defoaming efficiency of the defoaming agent on the water-based paint.

[0026] Furthermore, the diameter of the first gear 12 is smaller than the diameter of the second gear 14, so that when the reaction tank 1 swings back and forth, the first gear 12 can roll quickly on the second gear 14, so that the first stirring blade 13 and the second stirring blade 17 can quickly stir the defoaming agent and the water-based paint, which is conducive to full and uniform contact between the defoaming agent and the water-based paint.

[0027] The working principle of this utility model is as follows:

[0028] When in use, firstly, water-based paint and defoaming agent are put into the reaction tank 1 through the feed hopper 2, and then the motor 9 is started to drive the crankshaft 8 to rotate. The crankshaft 8 can slide up and down in the slide hole 7 by utilizing the circular motion of its curved section, so as to move the swing frame 6 to drive the reaction tank 1 to swing back and forth through the rotating shaft 4, so that the defoaming agent and water-based paint in the reaction tank 1 can move back and forth, and the defoaming agent and water-based paint are fully in contact;

[0029] When the reaction tank 1 swings back and forth, the first gear 12 can roll back and forth on the second gear 14, so that the first stirring shaft 11 can also drive each first stirring blade 13 to stir the defoaming agent and the water-based paint back and forth, so that the defoaming agent and the water-based paint are better and more fully contacted;

[0030] At the same time, when the first stirring shaft 11 rotates back and forth, the mutual engagement between the two third gears 16 can also enable the second stirring shaft 15 to drive each second stirring blade 17 to swing back and forth, and the second stirring blade 17 rotates in the opposite direction to the first stirring blade 13, further fully stirring and contacting the defoaming agent and the water-based paint, thereby further improving the defoaming efficiency of the defoaming agent on the water-based paint.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
