Description

TECHNICAL FIELD

[0001] The utility model belongs to metal degreasing, phosphating equipment technical field, concretely relates to a kind of degreasing phosphating tank. BACKGROUND

[0002] After the processing or welding polishing of metal products, especially black metal products, such as steel, the surface thereof needs to be sprayed. In order to make the sprayed layer better adhere to the surface of the product and improve the bonding strength of the coating and the product, and avoid peeling and other problems during use, the metal product needs to be degreased and phosphated, so as to significantly enhance the adhesion during the spraying process and improve the weather resistance and strength of the coating. In the traditional degreasing and phosphating process, the product is immersed in a degreasing solution, then washed with water, immersed in a phosphating tank for a certain period of time after the water washing is completed, taken out, washed with water again, and then dried before being sprayed. However, during the immersion process, the ion diffusion and movement ability in the tank is limited, so the concentration of effective substances around the product after reaction is reduced, and the substances at other positions do not have sufficient diffusion speed to supplement them, so that the reaction speed is difficult to maintain in a better state, and the consistency of the surface treatment of the product is difficult to guarantee. SUMMARY

[0003] The utility model aims to provide a kind of degreasing phosphating tank, which aims to improve the degreasing and phosphating effect of the surface of the product.

[0004] To solve the above technical problems, the utility model aims to achieve the following:

[0005] A degreasing phosphating tank includes a tank body and a plurality of circulating assemblies. The circulating assemblies are symmetrically arranged on the side wall of the tank body. The inlet of the circulating assembly is in communication with the position adjacent to the bottom of the tank body, and the outlet is in communication with the position adjacent to the upper edge of the tank body, so that the liquid in the tank body flows from top to bottom.

[0006] As a preferred embodiment of the above-mentioned scheme, the middle part of the bottom of the tank body has a raised portion upward, so that the bottom of the tank body is spherical. The edge of the raised portion is transitioned with the bottom arc of the tank body.

[0007] As a preferred embodiment of the above-mentioned scheme, the circulating assembly includes a circulating pump, a water inlet pipe and a water outlet pipe. The inlet of the water inlet pipe is in communication with the side wall of the tank body adjacent to the bottom of the tank body. The outlet of the water outlet pipe is in communication with the position adjacent to the upper edge of the tank body.

[0008] As a preferred embodiment of the above-mentioned scheme, the tank body is cylindrical, and the circulating assembly is distributed along the radial direction of the tank body.

[0009] The utility model discloses a compared with prior art outstanding and beneficial technical effect is: through the circulating pump of circulating assembly, inlet water line and outlet water line realize the liquid in the groove body forms the circulation flow from top to bottom, thereby make the liquid concentration area of each place in the groove body consistent, that is to say, the product can update the concentration of the substance reduced in time when carrying out the soaking treatment, thereby improve the reaction speed, shorten the processing time, improve production efficiency, in addition, the liquid of outlet water line export has certain flow rate, and it can be washed to the product surface placed in the groove body, thereby the product surface is washed more quickly, improves the effect of degreasing.

[0012] In order to make the purpose, technical scheme and advantage of the present application more clear, the technical scheme in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment, obviously, the described embodiment is only a part of the present application, instead of all the embodiments. Based on the embodiment given, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the scope of protection of the present application.

[0013] In the description of the present application, it needs to be understood that the orientation or position relationship indicated by the terms "upper", "lower" etc. is based on the orientation or position relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as the limitation of the present application.

[0014] In the description of the present application, the terms "first", "second" etc. are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0015] See Figures 1-2As shown, the application discloses a defatting phosphating tank, which comprises a tank body 10 and a plurality of circulating assemblies 20; the circulating assemblies 20 are symmetrically arranged on the side wall of the tank body 10, the inlet of the circulating assembly 20 is communicated with the position adjacent to the bottom of the tank body 10, and the outlet is communicated with the position adjacent to the upper edge of the tank body 10, so that the liquid in the tank body 10 flows from top to bottom. Specifically, in the embodiment, the circulating assembly 20 comprises a circulating pump 21, a water inlet pipeline 22 and a water outlet pipeline 23, the inlet 22a of the water inlet pipeline 22 is communicated with the position adjacent to the bottom of the tank body 10 on the side wall of the tank body 10, and the inlet 22a slightly extends into the tank body 10; the outlet 23a of the water outlet pipeline 23 is communicated with the position adjacent to the upper edge 11 of the tank body 10, and the outlet 23a slightly extends into the tank body 10. In this way, the liquid in the tank body 10 can be fully flowed as much as possible. Preferably, the tank body 10 is in a cylindrical shape, and the circulating assemblies 20 are distributed along the radial direction of the tank body 10, so that the liquid flows around the product more fully and avoids the existence of dead angles; in addition, such an arrangement can more fully make the flowing liquid more fully flush the surface of the product, thereby improving the reaction speed and shortening the defatting cleaning time.

[0016] In addition, in the embodiment, as shown in the detailed description Figure 2 As shown, it is further preferred that the middle part of the bottom of the tank body 10 has a raised portion 12 upwardly, so that the bottom of the tank body 10 is in a spherical shape; the edge of the raised portion 12 is connected to the bottom of the tank body 10 through a circular arc 13. The arrangement of the structure of the tank body bottom can make the liquid flowing from top to bottom flow along the bottom of the spherical tank to the periphery, and can accelerate the flow rate, so that the solid reactants existing in the tank can be dissolved more quickly, and the solid reactants are prevented from precipitating at the bottom of the tank, so as to be difficult to participate in the reaction or slowly participate in the reaction; thereby the utilization rate of the reactants can be improved, and the consistency of product processing can be effectively improved.

[0017] Of course, a filter can also be connected in series in the water inlet pipeline, so that the solid particles falling off from the surface of the product or the solid substances possibly generated in the reaction process are immediately filtered out, thereby avoiding that the product surface is scratched by the high-speed liquid flowing out at the outlet of the water outlet pipeline, and of course, the solid particles can also avoid the abrasion of the circulating pump.

[0018] The above embodiment is only a preferred embodiment of the present application, and does not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
