[0027] The anti-rust infiltration equipment provided by the application, preferably, further comprises a plurality of magnets; the magnets are arranged on the side wall of the infiltration tank.

[0028] The above technical scheme has the following advantages or beneficial effects:

[0029] The anti-rust infiltration method and equipment provided by the application, in step S101, since the anti-rust liquid has an optimal use temperature, the best anti-rust effect can be obtained when the anti-rust liquid is coated on the surface of the iron product at the optimal use temperature, therefore, when the iron product is subjected to anti-rust infiltration, it is necessary to ensure that the temperature of the anti-rust liquid is uniform and constant; by setting the flowing position of the heat exchange medium, the heat exchange medium surrounds the infiltration tank and exchanges heat with the anti-rust liquid in the infiltration tank, the heat exchange mode of surrounding type can effectively improve the heating efficiency of the anti-rust liquid, prevent the anti-rust liquid from cooling down too fast, and maintain the temperature of the anti-rust liquid; at the same time, compared with putting a single heat source into the infiltration tank to heat the anti-rust liquid, the heat exchange mode of surrounding type can effectively prevent the temperature of the anti-rust liquid from being too high at the local part and too low at the edge, so as to make the temperature of the anti-rust liquid uniform.

[0030] In step S102, since the optimal use temperature of different anti-rust liquids is different, it is necessary to preset the heating temperature of the anti-rust liquid; the heat exchange medium is heated at a constant temperature, that is, the heat exchange medium is maintained at a constant temperature, by maintaining the temperature of the heat exchange medium at the optimal use temperature, the temperature of the anti-rust liquid which exchanges heat with the heat exchange medium can also be maintained at the optimal use temperature; by the secondary heating mode of first heating the heat exchange medium and then heating the anti-rust liquid by the heat exchange medium, the problem of uneven heat distribution caused by heating by a single heat source can be effectively avoided, the temperature of the heat exchange medium is constant, so as to ensure that the anti-rust liquid is heated at a constant temperature, and the problem that the temperature of the anti-rust liquid at the local part is far higher than the optimal use temperature of the anti-rust liquid and causes the anti-rust liquid to fail can be avoided;

[0031] In step S103, the iron product is put into the soaking tank, and a soaking time is preset, which is affected by the viscosity of the rust-proof liquid and the oscillation frequency; the iron product is oscillated up and down in the rust-proof liquid, at this time, the iron product needs to be completely immersed in the rust-proof liquid, so that the iron product is in full contact with the rust-proof liquid; because the air on the surface of the iron product is gradually replaced by the rust-proof liquid when the iron product is immersed in the rust-proof liquid, the air is easily squeezed to generate bubbles, the bubbles isolate the rust-proof liquid from the surface of the iron product, thereby affecting the soaking quality of the iron product, by oscillating the iron product up and down, the bubbles generated on the surface of the iron product can be removed, so that the rust-proof liquid is in full contact with the surface of the iron product, and the soaking quality of the iron product is improved; at the same time, in the process of oscillating the iron product up and down, the rust-proof liquid in the middle part can be driven to flow to the edge, so as to promote the flow of the rust-proof liquid in the soaking tank, and further improve the heating efficiency and temperature uniformity of the rust-proof liquid;

[0039] The present application will be further described below in conjunction with the drawings and specific embodiments, but is not limited to the present application.

[0040] Embodiment 1:

[0041] As Figure 1As shown, the anti-rust infiltration method provided by the embodiment 1 of the present application comprises the following steps:

[0042] S101: Put the anti-rust liquid into the infiltration tank, and heat the infiltration tank by surrounding the infiltration tank with the heat exchange medium;

[0043] S102: Pre-set the heating temperature, and heat the heat exchange medium at constant temperature to maintain the anti-rust liquid at the pre-set heating temperature;

[0044] S103: Put the iron product into the infiltration tank, and pre-set the infiltration time, and oscillate the iron product up and down in the anti-rust liquid within the pre-set infiltration time;

[0045] S104: After the oscillation is completed, take out the iron product from the infiltration tank, and drain the anti-rust liquid on the surface of the iron product.

[0046] The anti-rust infiltration method provided by the present application, in step S101, because the anti-rust liquid has an optimal use temperature, when it is at the optimal use temperature, the best anti-rust effect can be obtained by coating it on the surface of the iron product, therefore, when the iron product is subjected to anti-rust infiltration, it is necessary to ensure that the temperature of the anti-rust liquid is uniform and constant; by setting the flow position of the heat exchange medium, the heat exchange medium surrounds the infiltration tank and exchanges heat with the anti-rust liquid in the infiltration tank, the surrounding type of heat exchange method can effectively improve the heating efficiency of the anti-rust liquid, prevent the anti-rust liquid from cooling down too fast, and maintain the temperature of the anti-rust liquid; at the same time, compared with putting a single heat source into the infiltration tank to heat the anti-rust liquid, the surrounding type of heat exchange method can effectively prevent the temperature of the anti-rust liquid from being too high at the edge and too low at the edge, so as to make the temperature of the anti-rust liquid uniform;

[0047] In step S102, because different anti-rust liquids correspond to different optimal use temperatures, it is necessary to pre-set the heating temperature of the anti-rust liquid; the heat exchange medium is heated at constant temperature, that is, the heat exchange medium is maintained at a constant temperature, by maintaining the temperature of the heat exchange medium at the optimal use temperature, the temperature of the anti-rust liquid which exchanges heat with the heat exchange medium can also be maintained at the optimal use temperature; by the secondary heating method of first heating the heat exchange medium and then heating the anti-rust liquid by the heat exchange medium, the problem of uneven heat distribution caused by single heat source heating can be effectively avoided, the temperature of the heat exchange medium is constant, so as to ensure that the anti-rust liquid is heated at constant temperature, and to avoid that the temperature of the anti-rust liquid far exceeds the optimal use temperature of the anti-rust liquid, which leads to the failure of the anti-rust liquid;

[0048] In step S103, the iron product is placed in the immersion tank, and the immersion time is preset, which is affected by the viscosity of the rust-proof liquid and the oscillation frequency; the iron product is oscillated up and down in the rust-proof liquid, at this time, the iron product needs to be completely immersed in the rust-proof liquid, so that the iron product is in full contact with the rust-proof liquid; because the iron product is immersed in the rust-proof liquid, the air on the surface of the iron product is gradually replaced by the rust-proof liquid, and the air is easily bubbled when being squeezed, the bubbles isolate the rust-proof liquid from the surface of the iron product, thereby affecting the immersion quality of the iron product, by oscillating the iron product up and down, the bubbles generated on the surface of the iron product can be removed, so that the rust-proof liquid is in full contact with the surface of the iron product, and the immersion quality of the iron product is improved; at the same time, in the process of oscillating the iron product up and down, the rust-proof liquid in the middle part can be driven to flow to the edge, so as to promote the flow of the rust-proof liquid in the immersion tank, and further improve the heating efficiency and temperature uniformity of the rust-proof liquid.

[0049] In step S104, after oscillation is completed, the iron product is fished out of the immersion tank, and the rust-proof liquid on the surface of the iron product is drained, and the rust-proof immersion operation of the iron product is completed.

[0050] Preferably, in step S101, the rust-proof liquid can adopt a water-based rust-proof agent or a rust-proof oil.

[0051] Preferably, in step S103, the iron product is placed in the immersion tank; the iron powder on the surface of the iron product and in the rust-proof liquid is adsorbed by a magnet; and the immersion time is preset, and the iron product is oscillated up and down in the rust-proof liquid within the preset immersion time.

[0052] Because the surface of the iron product may be left with iron powder after processing, if the iron product with iron powder is placed in the immersion tank, part of the iron powder still adheres to the surface of the iron product, and another part of the iron powder floats in the rust-proof liquid; if the iron powder is adsorbed on the surface of the iron product, the contact between the rust-proof liquid and the surface of the iron product is interrupted; the magnet can avoid the influence of the iron powder adhering to the iron product or floating in the rust-proof liquid on the immersion effect of the iron product, the magnet adsorbs the iron powder, so that the rust-proof liquid can be in full contact with the surface of the iron product, and the immersion quality of the iron product is improved; and the magnet adsorbs the iron powder, which is convenient for the user to recycle and clean the iron powder.

[0053] Preferably, in step S104, after the iron product is fished out of the immersion tank, the rust-proof liquid is filtered, and the adsorbed iron powder is cleaned.

[0054] In the rust-proof immersion operation of the iron product in batches, the magnet cannot adsorb too much iron powder, therefore, after one or more rust-proof immersion operations, the rust-proof liquid is filtered, and the iron powder adsorbed on the magnet is cleaned, so that the rust-proof effect of the iron product after immersion can be effectively maintained.

[0062] Further, since the coil pipe 41 is distributed around the side wall of the first inner cavity 11, the coil pipe 41 can surround the anti-rust liquid to heat, improving the heating efficiency of the anti-rust liquid; at the same time, the lifting plate 2 vibrates up and down in the first inner cavity 11, which can drive the anti-rust liquid in the middle part to flow to the edge, further improving the heating efficiency of the anti-rust liquid; compared with using a single heat source to heat in the first inner cavity 11, the surrounding heating mode can make the anti-rust liquid evenly heated, avoiding that the infiltrated workpiece cannot achieve the optimal anti-rust effect;

[0063] Further, when the workpiece is immersed in the anti-rust liquid, the air on the surface of the workpiece is gradually replaced by the anti-rust liquid, and air is easily produced when air is extruded, which affects the workpiece infiltration quality, for this purpose, the lifting plate 2 is vibrated up and down in the first inner cavity 11, which can remove the air bubbles generated on the surface of the workpiece, so that the anti-rust liquid fully contacts the surface of the workpiece, improving the workpiece infiltration quality;

[0064] In the prior art, since the anti-rust liquid has an optimal use temperature, in a cold environment, the anti-rust effect of the coated iron product may be poor; by using the anti-rust infiltration equipment provided by the embodiment 2 of the present application, the anti-rust liquid in the infiltration tank 1 is heated at constant temperature by the constant temperature mechanism 4 to maintain the temperature of the anti-rust liquid, so that the iron product is infiltrated in the anti-rust liquid at a suitable temperature, and the workpiece has the optimal anti-rust effect.
