Description

Technical Field

[0001] This utility model belongs to the field of steel wire surface treatment, and relates to a phosphating tank, specifically a phosphating device with external circulation function. Background Technology

[0002] The bead wire produced by drawing needs to pass through a phosphating tank for surface treatment. After a period of use, waste residue will accumulate at the bottom of the phosphating tank, affecting the heating effect. The concentration of the phosphating solution at the bottom will also be higher than that at the top, resulting in uneven phosphating of the wire.

[0003] Existing phosphating devices can also lift the liquid at the bottom of the tank to the upper layer through a booster pump to make the phosphating solution uniform, but they usually only perform overall internal circulation within the tank, resulting in poor circulation and poor circulation effect. Utility Model Content

[0004] To address the shortcomings of existing phosphating devices and further enhance the circulation capacity of the phosphating solution within the phosphating tank, this invention provides a phosphating device with an external circulation function, comprising an external circulation tank, a phosphating tank, a connecting channel, and a circulation pump.

[0005] The external circulation tank is located next to the phosphating tank, with its inner bottom surface higher than that of the phosphating tank. Both ends of the external circulation tank are connected to the upper layer of the phosphating tank. A connecting channel is formed by a downward indentation in the middle of the bottom surface of the external circulation tank, and this connecting channel is connected to the bottom side of the phosphating tank. A circulation pump is installed above the middle of the external circulation tank, with its impeller positioned within the connecting channel. Thus, the high-concentration phosphating solution at the bottom of the phosphating tank flows into the connecting channel and, under the lifting action of the circulation pump, into the external circulation tank, and finally into the upper layer of the phosphating tank, achieving forced circulation of the phosphating solution. Because the length and volume of the external circulation tank can be set relatively large, it can achieve a larger circulation volume and smoother circulation compared to a typical internal circulation system, ultimately resulting in a more uniform concentration of the phosphating solution within the phosphating tank.

[0006] Furthermore, the aforementioned phosphating device with external circulation function also includes a water replenishment interface, which is connected to one side of the external circulation tank and is used to adjust the concentration of the phosphating solution in real time during circulation.

[0007] Furthermore, the aforementioned phosphating device with external circulation function is characterized in that it further includes dividing lines, nylon brushes, and support bars; dividing lines are respectively installed at both ends of the phosphating tank, and a nylon brush is also provided next to the dividing line at one end; multiple support bars are arranged at intervals in the phosphating tank; multiple steel wires can enter the phosphating tank and contact the phosphating solution after passing through the dividing lines, while the nylon brush can brush away impurities on the surface of the steel wires, and the support bars can support the steel wires.

[0008] Furthermore, a front cover plate is hinged above the opening of the phosphating tank, and a rear cover plate is laid above the opening of the external circulation tank, making the device safer.

[0009] Through the above technical solutions, this utility model has at least the following beneficial effects:

[0010] The phosphating device with external circulation function described in this application, compared with the existing in-tank overall internal circulation phosphating device, can achieve forced circulation of phosphating solution by setting a larger volume external circulation tank next to the phosphating tank, which can have a larger circulation volume and smoother circulation, and can make the concentration of phosphating solution in the phosphating tank more uniform.

[0017] refer to Figures 1 to 3 A phosphating device with external circulation function includes an external circulation tank 1, a phosphating tank 2, a connecting channel 101 and a circulation pump 3;

[0018] The external circulation tank 1 is located next to the phosphating tank 2. The inner bottom surface of the external circulation tank 1 is higher than the inner bottom surface of the phosphating tank 2. Both ends of the external circulation tank 1 are connected to the upper layer of the phosphating tank 2.
