Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1

[0026] Please see Figures 1 to 3 This utility model is a filtration device for removing impurities from electroplating solution, including a water pump 1, a coarse filter component 2, and an impurity removal component 3. The impurity removal component 3 includes an impurity removal liquid loop pipe 301, a loop pipe sleeve 302, and a mixing component 303. By setting the coarse filter component 2 at the outlet end of the water pump 1 and the impurity removal component 3 at the outlet end of the coarse filter component 2, the water pump 1 pumps the electroplating solution into the coarse filter component 2 to filter and remove solid particulate impurities in the electroplating solution. The electroplating solution after filtering out solid particulate impurities flows into the impurity removal component 3, and an impurity removal agent is added to the electroplating solution through the impurity removal liquid loop pipe 301 in the impurity removal component 3. The electroplating solution after adding the impurity removal agent is discharged back into the electroplating tank and energized, thereby removing metal ion impurities in the electroplating solution.

[0027] Specifically, the impurity removal liquid ring pipe 301 is sleeved inside the ring pipe sleeve 302. The outer wall of the impurity removal liquid ring pipe 301 is connected to the inlet pipe 301a, which penetrates the ring pipe sleeve 302. A set of outlet holes 301b are circumferentially arrayed through the inner ring wall of the impurity removal liquid ring pipe 301. The mixing component 303 is located at the outlet of the lower end of the ring pipe sleeve 302. The coarse filter component 2 is located at the upper end of the ring pipe sleeve 302. The lower outlet end of the water pump 1 is connected to the upper end of the coarse filter component 2.

[0028] Furthermore, the coarse filter component 2 includes a coarse filter basket 201 and a basket sleeve 202. The lower end of the basket sleeve 202 is connected to the annular sleeve 302, and the upper end of the basket sleeve 202 is connected to the lower outlet end of the water pump 1 through a flange. The coarse filter basket 201 is a tube structure with an open upper end and a closed lower end. A set of coarse filter basket holes 201a are provided through the side wall and bottom of the coarse filter basket. A threaded sleeve 201b is fixed on the upper outer wall of the coarse filter basket 201. The threaded sleeve 201b is screwed into the upper inner wall of the basket sleeve 202. When the plating solution passes through the coarse filter basket holes 201a, it filters out solid impurity particles and retains them in the coarse filter basket 201.

[0029] The operation process in this embodiment is as follows:

[0030] Pump 1 pumps the electroplating solution from the electroplating tank into the coarse filter basket 202. When the electroplating solution passes through the coarse filter basket hole 201a, solid impurity particles are filtered and retained in the coarse filter basket 201. The electroplating solution after filtration through the coarse filter basket 202 enters the ring tube 302. The impurity removal solution enters the impurity removal solution ring tube 301 from the inlet pipe 301a and flows out from the outlet hole 301b, entering the electroplating solution flowing into the impurity removal solution ring tube 301. After being mixed by the mixing component, it is discharged back into the electroplating tank and energized to remove metal impurity ions from the electroplating solution.

[0031] Example 2

[0032] Please see Figures 1 to 5 Based on Example 1, the mixing component 303 includes a converging sleeve 303a, a rotating paddle 303b, and a rotating shaft seat 303c. By installing the converging sleeve 303a at the lower end of the annular sleeve 202, when the electroplating solution with added impurity remover flows into the converging sleeve 303a, it drives the rotating paddle 303b to rotate, thereby making the electroplating solution and the added impurity remover fully mixed.

[0033] Specifically, the convergence sleeve 303a is sleeved on the lower end of the annular sleeve 302, and the rotating shaft seat 303c is threaded onto the inner wall of the lower end of the convergence sleeve 303a. A set of connecting arms 303c-1 are fixedly arranged in a circumferential array on the inner wall of the rotating shaft seat 303c. A rotating shaft sleeve 303c-2 is fixedly provided at the end of each connecting arm 303c-1 away from the rotating shaft seat 303c. A rotating shaft 303b-1 is fixedly provided at the lower end of the rotating paddle 303b, and the rotating shaft 303b-1 is rotatably installed in the rotating shaft sleeve 303c-2.

[0034] Furthermore, a stirring paddle sleeve 303b-2 is threaded onto the outer side of one end of the rotating shaft 303b-1 that passes through the rotating shaft sleeve 303c-2. A set of stirring paddles 303b-3 are fixedly arranged in a circumferential array on the outer side wall of the stirring paddle sleeve 303b-2. When the electroplating solution passes through the rotating paddle 303b, it drives the rotating paddle 303b to rotate, which in turn drives the stirring paddles 303b-3 to rotate, thus mixing the electroplating solution with the impurity removal agent.

[0035] Furthermore, the converging sleeve 303a is integrally formed from top to bottom by an inlet section 303a-1, a converging section 303a-2, and an outlet section 303a-3. The converging section 303a-2 gradually converges downwards, and the rotating shaft seat 303c is threaded onto the inner wall of the outlet section 303a-3. The electroplating solution enters from the inlet section 303a-1, and after being converged by the converging section 303a-2, its flow rate increases, and then it flows out from the outlet section 303a-3, driving the rotating paddle 303b to rotate.

[0036] Furthermore, the outer wall of the outlet section 303a-3 is threaded with a liquid outlet pipe 303d, and the agitator 303b-3 is fitted onto the inner wall of the liquid outlet pipe 303d.

[0037] Furthermore, a flow-regulating sleeve 303d-1 is fixedly sleeved on the inner wall of the outlet pipe 303d. The flow-regulating sleeve 303d-1 is a tubular structure with openings at both the top and bottom. Flow-regulating plates 303d-2 are fixedly arranged in a circumferential array on the inner wall of the flow-regulating sleeve 303d-1. The surface of the flow-regulating plates 303d-2 is perpendicular to the pipe axis of the flow-regulating sleeve 303d-1. After the electroplating solution flows into the flow-regulating sleeve 303d-1, the eddy current generated by the rotation of the stirring paddle 303b disappears under the action of the flow-regulating plates 303d-2.

[0038] The operation process in this embodiment is as follows:

[0039] The electroplating solution enters from the inlet section 303a-1 and is accelerated after being constricted by the converging section 303a-2. It then flows out from the outlet section 303a-3. When the electroplating solution passes through the rotating paddle 303b, it drives the rotating paddle 303b to rotate, which in turn drives the stirring paddle 303b-3 to rotate, thus mixing the electroplating solution with the impurity remover. After the electroplating solution flows into the constant flow tube sleeve 303d-1, the eddies generated by the rotation of the stirring paddle 303b disappear under the action of the constant flow plate 303d-2. Furthermore, the eddies collide with the constant flow plate 303d-2, further mixing the impurity remover with the electroplating solution.
