[0042] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] like Figure 1-6 As shown, the present invention provides an integrated bolt protection device and method. The integrated bolt protection device includes:

[0045] The soaking tank 1 has a mesh rotating cylinder 12 connected to the agitation component inside, and the soaking tank 1 is filled with rust removal liquid.

[0046] Neutralizing liquid storage tank 2 is filled with neutralizing liquid and the interior of the neutralizing liquid storage tank (2) is divided into multiple independent spaces by a partition (21);

[0047] Passivating agent storage tank 3, which is equipped with passivating agent inside;

[0048] Rust inhibitor storage tank 4 is filled with rust inhibitor and is connected to air storage tank 5 and spray gun.

[0049] In practice, the soaking tank 1 is equipped with a mesh rotating drum 12 inside. The bolts and / or nuts to be treated are placed inside the mesh rotating drum 12. The agitation component can drive the mesh rotating drum 12 to rotate, ensuring that the rust removal liquid penetrates into the rust layer and achieves a better rust removal effect. The neutralizing liquid storage tank 2 is equipped with a partition 21 inside. The partition 21 is in the shape of a straight line or a cross, which can divide the interior of the neutralizing liquid storage tank 2 into two or four areas, enabling multi-stage neutralization. The bottom of the rust-preventive liquid storage tank 4 is equipped with a base. One side of the rust-preventive liquid storage tank body 41 is equipped with a liquid outlet pipe 42. The top of the rust-preventive liquid storage tank body 41 is equipped with an opening, and a suitable tank cover 43 is provided at the opening. The bottom of the air storage tank body 51 of the air storage tank 5 is equipped with a base, and the top is equipped with an air inlet pipe 52, an air outlet pipe 53, a pressure gauge 54, and a safety valve 55. The rust-preventive liquid storage tank 4 and the air storage tank 5 are used in conjunction with the use of the rust-preventive liquid spray gun to spray the rust-preventive liquid onto the outside of the bolts and nuts.

[0050] In some embodiments, the soaking tank 1 includes an outer cylinder 11 and a first cylinder cover 13, a mesh rotating cylinder 12 is disposed inside the outer cylinder 11, and the first cylinder cover 13 is adapted to the outer cylinder 11 and fastened to the opening at the top of the outer cylinder 11.

[0051] In practice, the outer cylinder 11 and the first cylinder cover 13 are naturally sealed by the smoothness of the surface, or a sealing gasket can be added.

[0052] In some embodiments, the disturbance component includes a rotating shaft 14, a first handwheel 15, and a bearing 16. The bearing 16 is disposed on the first cylinder cover 13, the rotating shaft 14 passes through the bearing 16 and is connected to the mesh rotating cylinder 12, and the first handwheel 15 is disposed on the rotating shaft 14 at one end away from the mesh rotating cylinder 12.

[0053] In practice, the first handwheel 15 is turned to drive the rotating shaft 14 to rotate within the bearing 16. The rotating shaft 14 drives the mesh rotating drum 12 to rotate. The rotation of the mesh rotating drum 12 disturbs the bolts and nuts inside the mesh rotating drum, thereby improving the rust removal effect.

[0054] In some implementations, the passivation agent storage tank 3 includes a cylinder 31, a support 32, an adjusting screw 33, a second handwheel 34, a lifting ring 35, a connecting chain 36, and a second cylinder cover 37. One end of the support 32 is fixedly installed on one side of the outer edge of the cylinder 31, and the other end of the support 32 has a screw hole. The adjusting screw 33 is adapted to be installed in the screw hole. The adjusting screw 33 is coaxially installed with the cylinder 31. The end of the adjusting screw 33 near the cylinder 31 is fixedly connected to the second cylinder cover 37 through the connecting chain 36 and the lifting ring 35. The second cylinder cover 37 can be fastened to the cylinder 31.

[0055] In specific implementation, the bracket 32 ​​is an L-shaped support frame. Its relatively long end is vertically fixed to one side of the outer edge of the cylinder 31, and the other end is horizontally placed on the cylinder 31 with a screw hole. When the second handwheel 34 is turned, the adjusting screw 33 is driven to rotate. The position of the second cylinder cover 37 is controlled by the lifting ring 35 and the connecting iron chain 36. The top of the cylinder 31 is provided with a groove, and the second cylinder cover 37 is provided with a protrusion relative to the groove. The seal is achieved by the matching and meshing of the protrusion and the groove.

[0056] On the other hand, this application also provides a protection method applied to an integrated bolt protection device, specifically including the following steps:

[0057] S1. Place the bolts and / or nuts to be treated in a soaking tank 1 containing rust removal solution for soaking and rust removal for a soaking time of not less than 12 hours;

[0058] S2. After soaking in the soaking tank 1, the bolts and / or nuts are soaked in the neutralizing liquid storage tank 2 containing the neutralizing liquid for neutralization, and the neutralization is carried out 2-4 times.

[0059] S3. Place the neutralized bolts and / or nuts in a passivating agent storage tank 3 containing passivating agent for passivation;

[0060] S4. Dry the passivated bolts and / or nuts;

[0061] S5. Spray rust-preventive liquid onto the dried bolts and / or nuts to form a rust-preventive coating.

[0062] In practice, bolts and nuts are soaked in soaking tank 1 for rust removal for more than 12 hours. Then they are transferred to neutralization solution storage tank 2 for neutralization. Neutralization solution storage tank 2 is equipped with baffles 21, which allows for 2-4 neutralization cycles to achieve a better neutralization effect. Then they are transferred to passivation agent storage tank 3 for passivation. Finally, they are dried and sprayed with rust inhibitor to achieve long-term protection.

[0063] In some embodiments, in S1, bolts and / or nuts are placed inside a mesh drum 12, and the mesh drum 12 is rotated during the soaking process to agitate the soaking bolts and / or nuts.

[0064] In practice, the rust removal effect can be improved by rotating the mesh drum 12 to agitate the soaked bolts and / or nuts. During this process, a wire brush can be used to disturb the rust layer on the bolts and nuts to ensure that the rust removal liquid penetrates into the rust layer and achieves a better rust removal effect.

[0065] In some embodiments, the rust remover comprises the following components in parts by volume:

[0066] 1 part alcohol; 1 part dish soap; 1.5 parts acetic acid solution; 6.5 parts purified water.

[0067] In practice, mix 100 ml of alcohol (one part alcohol), 100 ml of dish soap (one part dish soap), 150 ml of acetic acid solution (one and a half parts acetic acid solution), and 650 ml of purified water (six and a half parts purified water). Combine the four solutions thoroughly and stir well. Place the mixture in a sealable container. Immerse the bolts that need rust removal in the prepared solution for at least 12 hours. This utilizes the wetting properties of alcohol, the decomposing and peeling properties of dish soap, and the acidity of acetic acid to react chemically with ferric oxide and magnetite.

[0068] In some embodiments, the rust remover may also comprise the following components in parts by weight: 1 part alcohol, 1 part dishwashing liquid, 1 part citric acid, and 7 parts purified water.

[0069] In some embodiments, the neutralizing solution comprises the following components in parts by weight:

[0070] 1 part soda ash; 24 parts purified water.

[0071] In practice, the solution includes 20 grams of soda ash (one part soda ash) and 480 ml of purified water (24 parts purified water). This solution is alkaline and can neutralize the bolts, eliminating the acidity carried over from soaking in the acetic acid solution. Simply immerse the bolts completely in the neutralizing solution for 10-15 minutes.

[0072] In some embodiments, the passivating agent is one or a combination of passivating agents, lubricating oils, and lubricating greases.

[0073] In practice, the passivating agent is evenly mixed with lubricating oil or grease and then applied to the inner and outer surfaces of the bolts and nuts to achieve passivation, minimizing the corrosion rate and preventing rust. Commonly used passivating agents are carbonyl condensates of amines, such as N,N′-disaccharide-1,2-propanediamine. Metal passivating agents react with metal ions to form chelates, placing the metal in a passivated state that eliminates its oxidation-promoting effects. The addition amount is approximately 0.0003–0.001% (by weight).

[0074] In some embodiments, the anti-rust coating is an anti-rust enamel.

[0075] In practice, the cleaned bolts and nuts are placed on a wire mesh rack and dried with hot air using a hair dryer. During the drying process, the bolts and nuts are kept at a certain temperature for 3-5 minutes to ensure they are thoroughly dried. The rust inhibitor or rust-preventive liquid to be sprayed includes thinner and rust-preventive paint. The rust-preventive paint is mixed with thinner and sprayed evenly on the outer surface of the bolts and nuts to form a rust-preventive coating. After drying fully under natural conditions, they are placed in a storage box for later use.
