Description

Technical Field

[0001] The utility model relates to the technical field of paint production, in particular to a closed paint powder dispersion device. Background Art

[0002] Paint dispersion refers to stably and evenly dispersing pigments in a solid state in a specific medium, which is one of the key steps in preparing colored paints. There are many ways of paint dispersion, among which the common ones are mechanical dispersion and chemical dispersion. Mechanical dispersion means separating pigments from the original medium by mechanical force and then dispersing them in a new medium through methods such as screening and grading; chemical dispersion means that under the action of chemicals such as surfactants and colloid stabilizers in the solution, the pigments are evenly dispersed in the medium.

[0003] In the mechanical dispersion process, a disperser is usually used to break up paint powder. For example, a paint disperser disclosed in patent CN220900326U drives a dispersion moving shaft, a spiral dispersion plate and a diversion inclined plate to move together through a gear set when working, so as to disperse the paint in the storage barrel. However, the upper end of its storage barrel is an open structure. When adding paint powder into the storage barrel or during the stirring process, a large amount of dust will be generated or the paint will splash out. The dust will pollute the production environment and there is a risk of being inhaled by workers; the splashed paint has extremely strong adhesion, especially it is very difficult to clean it after drying, making the paint residues everywhere on the workshop floor, production equipment and workers' clothes, seriously affecting the cleanliness of the production environment.

[0004] Therefore, the existing paint dispersion devices need to be improved. Content of the Utility Model

A plurality of stirring blades are arranged at the lower end of the stirring shaft. The feeding mechanism is arranged on the base and on one side of the dispersion tank. A feeding port is arranged on the sealing cover, a discharge port is arranged at the bottom of the dispersion tank, and a discharge pipe is connected to the discharge port and extends outside the support seat.

[0006] Further, the feeding mechanism includes a feeding pump, a feed pipe, a feeding pipe, a rotary joint, and a telescopic pipe. The feeding pump is fixedly arranged on the base.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0021] In the description of the embodiments, unless otherwise clearly specified and limited, terms such as "set" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or connected through an intermediate medium, or the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] As Figures 1-3 shown, the closed - type coating powder dispersion device in this embodiment includes a base 1, a support base 2, a dispersion tank 3, a sealing cover 4, a stirring motor 5, a stirring shaft 6, stirring blades 7, and a feeding mechanism. The support base 2 is arranged on the base 1, the dispersion tank 3 is arranged on the support base 2, the sealing cover 4 is arranged on the top of the dispersion tank 3, the stirring motor 5 is arranged on the sealing cover 4, the stirring shaft 6 is arranged at the bottom of the stirring motor 5 and passes through the sealing cover 4 and extends into the dispersion tank 3, and a plurality of stirring blades 7 are arranged at the lower end of the stirring shaft 6; the stirring motor 5 drives the stirring shaft 6 and the stirring blades 7 to rotate, so as to disperse the coating in the dispersion tank 3.

[0023] The sealing cover 4 is provided with a feeding port 8, and a sealing plate 9 is arranged outside the feeding port 8. One end of the sealing plate 9 is rotatably connected to the sealing cover 4 through a hinge 10, and the other end is locked to the sealing cover 4 through a bolt 11. The feeding port 8 is used to add powder materials and a dispersion medium (mainly water) into the dispersion tank 3. Among them, the powder materials are added into the tank through a special powder conveyor, and the dispersion medium is added into the tank through a feeding mechanism. When feeding, loosen the bolt 11 and turn up the sealing plate 9 upward to expose the feeding port 8. At this time, materials can be added into the dispersion tank 3. After feeding is completed, close the sealing plate 9 and tighten the bolt 11.

[0024] The bottom of the dispersion tank 3 is of a funnel-shaped structure. An outlet 12 is arranged at the central position of the bottom of the dispersion tank 3, and a discharge pipe 13 is connected to the outlet 12. The discharge pipe 13 extends outside the support base, and a discharge valve 14 is further arranged at the end of the discharge pipe 13. When the coating dispersion is completed, open the discharge valve 14, and the coating in the dispersion tank 3 flows out from the discharge pipe 13, and the funnel-shaped tank bottom helps to discharge the coating completely.

[0025] A liquid level gauge 15 is arranged on the outer wall of the dispersion tank 3, and both the upper and lower ends of the liquid level gauge 15 are communicated with the inside of the dispersion tank 3. Specifically, the liquid level gauge 15 can adopt a magnetic flap liquid level gauge, which is made according to the buoyancy principle and magnetic coupling principle. When the liquid level in the dispersion tank 3 rises or falls, the magnetic float in the main body pipe of the liquid level gauge also rises or falls accordingly. The permanent magnet in the float transmits through magnetic coupling to the magnetic flap indicator, driving the red and white flaps to flip 180°. When the liquid level rises, the flaps change from white to red, and when the liquid level falls, the flaps change from red to white. The red and white junction of the indicator is the actual height of the liquid level inside the container, thus realizing clear indication of the liquid level in the dispersion tank 3.

[0026] The feeding mechanism is arranged on the base 1 and is located on one side of the dispersion tank 3. The feeding mechanism includes a feeding pump 16, a feed pipe 17, a feeding pipe 18, a rotary joint 19 and a telescopic pipe 20. The feeding pump 16 is fixedly arranged on the base 1, the feed pipe 17 is connected to the inlet of the feeding pump 16, the feeding pipe 18 is arranged on one side of the dispersion tank 3 through a connecting bracket 21 and the lower end is connected to the outlet of the feeding pump 16, the rotary joint 19 is arranged at the upper end of the feeding pipe 18, and the telescopic pipe 20 is arranged at the end of the rotary joint 19; among them, the telescopic pipe 20 can adopt a tubular structure such as a corrugated pipe.

[0027] When it is necessary to add a dispersion medium into the dispersion tank 3, rotate the rotary joint 19 to align and insert the telescopic pipe 20 into the feeding port 8, and then start the feeding pump 16 to extract and feed the dispersion medium into the dispersion tank 3. During the feeding and dispersion process, the dispersion tank 3 is always in a closed state, and there will be no problems such as dust diffusion or coating splashing, which is beneficial to keeping the production environment clean and tidy, reducing the pollution of the production environment by dust and the harm caused to the workers' bodies.
