Technical Field

[0001] The invention belongs to the technical field of paint storage devices, and in particular relates to a nano-level photocatalyst paint storage device. Background Art

[0002] Titanium dioxide photocatalyst coatings are mainly used in indoor environmental purification and other fields. After being coated on the surface of various substrates, they can absorb light energy equivalent to below the band gap energy under light, causing their surface to be excited to produce electrons (e-) and holes (h+); these electrons and holes have strong reduction and oxidation capabilities, and can react with water or stored oxygen to produce hydroxyl free radicals (·0H) and super anion ions (·0) with extremely strong oxidation capabilities, which can decompose or harmlessly treat various harmful chemicals and malodorous substances, thereby achieving the purpose of purifying the air and resisting pollution and deodorizing.

[0003] In the prior art, titanium dioxide photocatalyst coatings are usually poured into a tank for storage. Since the composite liquid in the tank is usually in a static state, the composite liquid is prone to stratification after a certain period of time, resulting in the need to vigorously shake the tank when taking the coating in the tank to ensure the effectiveness of the particle concentration in the composite liquid taken, but this method consumes too much physical strength of the workers. However, the stirring blades of the prior art can generally only stir horizontally, requiring more time and electricity to stir evenly, and it cannot be sprayed, and needs to be discharged before spraying, which is inefficient and time-consuming and labor-intensive. Therefore, we propose a nanoscale photocatalyst coating storage device. Summary of the invention

The water inlet pipe of the submersible pump 14 passes through the shell of the storage tank 6 and extends into the interior thereof.

[0032] The main shaft 7 is sleeved with a first sleeve 12 , and a first annular mounting plate 11 is welded to the first sleeve 12 through a connecting pipe, and a plurality of stirring blades 10 are embedded on the first annular mounting plate 11 .

[0033] The first sleeve 12 is connected to the main shaft 7 by bolts, and the stirring blade 10 is a ceramic wear-resistant plate.

[0034] The vertical lifting stirring mechanism 8 includes a second annular mounting plate 83 , the upper part of which is connected to a first connector 81 , the first connector 81 is connected to a first tube body 82 , the second annular mounting plate 83 is connected to a second sleeve 84 via a first connecting rod 85 , and the second sleeve 84 is connected to the main shaft 7 .

[0035] The first connector 81 includes a first semicircular clamp 812 and a first connecting plate 811 , and the first semicircular clamp 812 and the first connecting plate 811 are connected by bolts.

[0036] The first tube body 82 is provided with a chamfered portion 821 , and the first tube body 82 is provided with a vertical portion 822 .

[0039] Working principle: The vertical lifting stirring mechanism 8 comprises a second annular mounting plate 83, a first connector 81 and a first tube body 82, wherein the first connector 81 is composed of a first semicircular clamp 812 and a first connecting plate 811. The mechanism connects the second annular mounting plate 83 with the second sleeve 84 through a first connecting rod 85, and the latter is fixedly connected to the main shaft 7. The first tube body 82 is provided with a chamfered portion 821 and a vertical portion 822, and this design enables the paint to form a spiral upward flow in the storage tank 6 during stirring.

[0040] Existing paint storage devices often cannot effectively prevent the paint from stratification or sedimentation when it is stationary, especially when storing nano-scale photocatalyst paint, the sedimentation of particles will cause the paint performance to deteriorate. The design of the vertical lifting stirring mechanism 8 ensures that the paint can maintain a uniform state during storage, avoiding the sedimentation problem, thereby improving the stability and use effect of the paint.

[0041] The submersible pump 14 and the air pump 13 are respectively installed in the water pump housing 5 and the nozzle magnetic suction housing 3, and are connected to the spray gun 16 through a hose. A mixing chamber is provided in the spray gun 16 for mixing air and paint and spraying them through the nozzle 4. An iron sleeve is fixed on the outside of the spray gun 16, which increases the stability and durability of the spray gun 16.

[0042] Conventional spraying equipment often has difficulty in achieving uniform spraying of nano-scale coatings, especially for coatings with high viscosity, which are prone to problems such as uneven spraying and clogging. The present invention effectively solves this problem by using a submersible pump 14 and an air pump 13 in combination.

[0043] The submersible pump 14 can extract the paint in the storage tank 6 and atomize it through the compressed air provided by the air pump 13, ensuring that the paint can be evenly sprayed on the target surface. The mixing chamber design inside the spray gun 16 allows the air and paint to be fully mixed before spraying, further improving the uniformity and adhesion of the spraying. The use of the iron sleeve increases the mechanical strength of the spray gun 16, prevents the wear problem after long-term use, and extends the service life of the spray gun 16.

[0044] When in use, first add the nano-scale photocatalyst coating into the storage tank 6 through the feed port 2. At this time, the cover installed on the upper part of the feed port 2 ensures the sealing during the feeding process to prevent the coating from leaking.

[0045] When the paint is added to the storage tank 6, the DC motor 1 located at the upper part of the storage tank 6 is started. The lower end of the output shaft of the DC motor 1 passes through the top of the storage tank 6 and is connected to the main shaft 7, driving the main shaft 7 to rotate. The main shaft 7 is equipped with a vertical lifting stirring mechanism 8 and an oblique lifting stirring mechanism 9, and as the main shaft 7 rotates, these two mechanisms also start to operate.

[0046] The vertical lifting and stirring mechanism 8 is connected to the main shaft 7 through the second annular mounting plate 83 and the first connector 81. The first connector 81 includes a first semicircular clamp 812 and a first connecting plate 811, which are connected by bolts to ensure the stability of the connection. The first tube body 82 is provided with a chamfered portion 821 and a vertical portion 822. As the main shaft 7 rotates, the first tube body 82 forms a spiral upward flow in the paint, driving the paint to move upward, thereby realizing vertical lifting and stirring.

[0047] The oblique lifting and stirring mechanism 9 is connected to the main shaft 7 through the third annular mounting plate 91 and the second connector 92. The second tube body 93 includes a transverse portion 931 and an oblique portion 932, and the angle between the two is 30-45 degrees. As the main shaft 7 rotates, the second tube body 93 generates an oblique driving force in the paint, causing the paint to flow in the horizontal direction, and combined with the vertical lifting and stirring, realizes multi-dimensional uniform mixing of the paint in the storage tank 6.

[0048] During the stirring process, the plurality of stirring blades 10 embedded on the first annular mounting plate 11 rotate with the main shaft 7, further enhancing the mixing effect of the coating. The stirring blades 10 are ceramic wear-resistant plates with good wear resistance and corrosion resistance, and are suitable for stirring the nano-level photocatalyst coating for a long time without being easily damaged.

[0049] After the stirring is completed, the submersible pump 14 and the air pump 13 are started. The submersible pump 14 is located in the water pump housing 5, and draws the paint from the storage tank 6 through the water inlet pipe and delivers it to the spray gun 16 through a hose. The air pump 13 is located in the nozzle magnetic suction housing 3, and provides compressed air to the spray gun 16 through another hose. The spray gun 16 is provided with a mixing chamber for mixing air and paint and spraying them through the nozzle 4.

[0050] The iron sleeve of the spray gun 16 enhances the stability and durability of the spray gun 16, and the spray head 4 is fixed by the spray head magnetic suction box 3, which is convenient for disassembly and replacement. The synergistic effect of the submersible pump 14 and the air pump 13 enables the paint to be evenly atomized before spraying, ensuring the uniformity and adhesion of the spraying.

[0051] During the entire working process, the battery 15 provides power support for the submersible pump 14 and the air pump 13. The battery 15 is covered with a waterproof shell to prevent water from invading and ensure the safe operation of the electrical components. A charging port is provided on the front side of the water pump housing 5 to facilitate charging and maintenance of the battery 15.

[0052] Through the above working principle, the present invention realizes an efficient integrated solution for storage and spraying of nano-scale photocatalyst coatings, which not only ensures uniform mixing of the coatings during storage, but also improves the spraying efficiency and quality, and has important practical value.

[0053] The above embodiments are only used to help understand the method and core idea of ​​the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
