[0031] The preferred embodiments of the present application will be described in detail below with reference to the drawings, wherein the drawings form a part of the present application, and are used together with the embodiments of the present application to explain the principles of the present application, and are not used to limit the scope of the present application.

[0032] The self-circulating stirring device of the paint storage tank in the present embodiment relates to the paint stirring technical field, the liquid and the gas are input to the bottom layer of the liquid paint in the tank body 100, the stirring of the liquid paint is realized, the substances precipitated in the lower layer of the tank body 100 are floated, the uniform distribution of the substances of the liquid paint is promoted, and the consistency of the filling product is improved.

[0033] Please refer to Figures 1 to 6The self-circulation stirring device of the paint storage tank in the embodiment comprises a tank body 100, a liquid circulation stirring system 200, and a gas circulation stirring system 300. The tank body 100 is used for storing liquid paint. The liquid circulation stirring system 200 can input liquid paint to the lower layer of the tank body 100, impact stir the relatively thick paint, and promote the uniform distribution of substances. The gas circulation stirring system 300 can input gas to the lower layer of the tank body 100. The gas can promote the substances in the liquid paint to uniformly diffuse to the upper layer, and promote the uniform distribution of substances.

[0034] The liquid circulation stirring system 200 comprises a plurality of liquid jet units 210 arranged in the tank body 100. The liquid jet units 210 extract liquid paint from the middle or upper part of the tank body 100, and spray the liquid paint at high speed to the bottom after pressurization. The liquid has a large kinetic energy during the spraying process, which can effectively stir the liquid inside the tank body 100, promote the thorough mixing of thick sediments and relatively thin upper paint, break the stratification phenomenon formed due to standing, and ensure the uniformity of the liquid paint during filling.

[0035] The gas circulation stirring system 300 comprises an aeration nozzle 310 arranged in the tank body 100. The aeration nozzle 310 is downwardly open. The aeration nozzle 310 can spray a large amount of gas downward from the bottom of the tank body 100. The bubbles formed by the gas automatically float upward after impacting the thick paint downward, drive the paint substances to mix with the relatively thin liquid in the upper part, and promote the uniform distribution of substances. The aeration nozzle 310 can be unidirectionally opened from inside to outside, which can avoid the liquid paint in the tank body 100 from entering the aeration nozzle 310, so that the aeration nozzle 310 is not blocked.

[0036] The liquid sprayed by the liquid jet units 210 can make the paint flow in a large range and break the stratification. The aeration nozzle 310 can microscopically disturb the liquid by the rising of bubbles, ensure the further refined mixing of the thick paint at the bottom and the thin paint in the upper part, and maintain the dynamic balance of the paint during storage. Even if the tank body 100 is left standing for a period of time, the paint still maintains a uniform state. During filling, the thin or excessively thick paint can be avoided, and the product quality consistency can be ensured every time.

[0037] In some embodiments, please refer to Figures 2 to 4, the aeration nozzle 310 includes a nozzle body 311 and a one-way valve 312, the nozzle body 311 is provided with an inner cavity for storing high-pressure air, one end of the nozzle body 311 is provided with a plurality of communication holes, both ends of the communication holes are communicated with the inner cavity of the nozzle body 311 and the outside, and the high-pressure air in the inner cavity can be sprayed into the liquid paint outside through the communication holes. The one-way valve 312 is arranged in the communication hole, and the one-way valve 312 in the nozzle ensures that the gas can only pass in one direction, that is, the high-pressure air can be sprayed outwards from the inner cavity, but the liquid outside cannot flow back into the inner cavity of the nozzle through the communication hole. The arrangement of the one-way valve 312 can prevent the liquid paint in the storage tank, especially the relatively viscous paint, from flowing back into the gas pipeline, avoid pipeline blockage and equipment damage, improve the service life and reliability of the equipment.

[0038] The one-way valve 312 is a spring type one-way valve 312, which includes a spring and a valve core arranged in the communication hole. When there is no gas pressure, the spring presses the valve core against the valve seat. When there is gas flow, the gas pressure pushes the valve core away, allowing the gas to pass. Once the gas flow stops or reverses, the spring makes the valve core return to the closed position to prevent backflow.

[0039] The one-way valve 312 is a ball type one-way valve 312, which uses a lightweight ball as a valve core. When the gas flow is forward, the gas pressure pushes the ball away, and the gas passes through. When the gas flow is reversed, the ball returns to the valve seat under the action of gravity or pressure, closing the channel.

[0040] The one-way valve 312 is a check valve, and the valve core of the check valve can swing freely. When the forward gas flow pushes the valve core away, the gas passes through. When the reverse liquid flow, the valve core closes under the action of gravity or reverse pressure.

[0041] In some embodiments, referring to Figure 1 The gas circulation stirring system 300 further includes an air driver 320, one end of the air driver 320 is communicated with the nozzle body 311 through a pipeline, and the other end of the air driver 320 is communicated with the top of the tank body 100 through a pipeline. The gas released from the nozzle body 311 forms floating bubbles, the bubbles break at the liquid surface, releasing the gas into the upper cavity of the tank body 100. The gas may contain some solvents or irritating substances, and the air driver 320 can recover this part of the gas, for secondary action on the liquid paint in the tank body 100, avoiding direct discharge of the gas into the air, causing waste and continuous pollution.

[0042] In the specific implementation process, the air driver 320 is an air compressor, a fan or an air pump, which can generate strong suction power, pressurize the air and promote the movement of the air.

[0043] In some embodiments, referring to Figure 2 and Figure 5The liquid spouting unit 210 comprises a submersible pump 211 arranged at the bottom of the tank body 100, and the shell of the submersible pump 211 is fixedly connected with the inner wall of the tank body 100. The liquid inlet of the submersible pump 211 is communicated with the upper layer of the liquid coating through a pipeline, and the liquid outlet of the submersible pump 211 is arranged opposite to the lower layer of the liquid coating. The submersible pump 211 generates an attraction force on the liquid coating and an impact force on the layer of the liquid coating, so as to promote the liquid in the lower layer to move to the upper layer and promote the uniform distribution of the position.

[0044] As a further embodiment, the liquid spouting unit 210 further comprises a movable spouting head 212, which is a bellows spray head. The spouting head 212 is connected with the liquid outlet of the submersible pump 211. The bellows spray head can swing under the reaction of the spouting liquid, and the spouting head can automatically adjust according to the change of the reaction force of the liquid. The swing state of the bellows spray head can effectively expand the area covered by the liquid spouting, and enhance the flowability of the liquid at different positions in the tank body 100, so as to avoid the stirring dead angle and ensure the uniform distribution of the coating in the entire storage tank.

[0045] In some embodiments, referring to Figure 2 and Figure 6 The self-circulating stirring device of the paint storage tank further comprises an anti-spouting assembly 400, which comprises an anti-spouting screen 410 arranged above the tank body 100 and installed along the cross section of the tank body 100. The anti-spouting screen 410 can effectively block the liquid spouting caused by the action of gas or liquid in the tank body 100, so as to avoid the overflow of the paint spouting and reduce the leakage of the liquid coating, thereby effectively reducing the waste of materials.

[0046] As a further embodiment, the anti-spouting assembly 400 further comprises a buoyancy ring 420, which is arranged to float on the surface of the liquid coating, and the anti-spouting screen 410 is connected with the buoyancy ring 420. The buoyancy ring 420 can automatically float with the rise and fall of the liquid surface of the liquid coating, so that the anti-spouting screen 410 is always near the liquid surface and dynamically adapts to different liquid levels. The anti-spouting screen 410 can always maintain a set height from the liquid surface, so as to avoid that the height of the anti-spouting screen 410 is too high or too low relative to the liquid surface, which interferes with the corresponding blocking effect of the anti-spouting screen 410.

[0047] Workflow: First, the liquid circulation stirring system 200 starts, the submersible pump 211 extracts the paint from the bottom or middle of the storage tank. The extracted paint is pumped to the bottom of the storage tank and sprayed back into the tank through the corrugated pipe nozzle. The corrugated pipe nozzle can swing, so that the liquid is sprayed at multiple angles, increasing the coverage of the stirring, pushing the paint to flow uniformly in the storage tank, thereby avoiding the stratification and precipitation of the liquid paint. Then, the gas circulation stirring system 300 assists in mixing, and the aeration nozzle 310 sprays a large amount of high-pressure gas through the one-way valve 312 to inject air into the paint to form bubbles. The sprayed gas churns upward, and the bubbles disturb the paint during their upward journey in the liquid, promoting the mixing of the upper and lower layers of paint. The disturbance of the gas enhances the flowability of the paint, further disrupting the stratification of the liquid paint and ensuring uniform distribution of the paint in each layer.

[0048] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the present application.
