Description

Technical Field

The high-efficiency pickling device for pre-treatment of titanium alloy electroplating has good pickling effect and high efficiency, avoids over-pickling caused by too long pickling time, has oxygen supply capability, and avoids hydrogen penetration into the titanium alloy matrix during the pickling process.

[0003] In the prior art, during the pickling process of titanium alloy, the cleaning effect is achieved through a cleaning unit and an oxygen supply unit. At the same time, the solution tanks arranged on both sides of the prior art can continuously replenish the pickling solution, thereby improving the pickling efficiency. However, after the pickling of the titanium alloy is completed, the pickling solution needs to be replenished. During the long replenishment process, the concentration of the pickling solution will not meet the conditions for the pickling of the titanium alloy, which will increase the pickling time of the titanium alloy, thereby reducing the pickling efficiency of the titanium alloy.

[0004] Therefore, we designed a high-efficiency pickling device for titanium alloy pre-plating treatment. Utility Model Content

DETAILED DESCRIPTION

[0021] Reference Figure 1-Figure 4 A high-efficiency pickling device for titanium alloy electroplating pretreatment includes a pickling box 1. The pickling box 1 is a prior art and is mainly used for immersing titanium alloy parts in a pickling solution. The pickling work is completed by contacting the hydrogen in the pickling solution with the titanium alloy surface, and the pickling efficiency depends on the concentration of the pickling solution. The shelf net 2 is a prior art and is easy to take out of the titanium alloy parts after pickling through special acid-resistant treatment. The slide bar 3 is a component for fixing the shelf net 2 in the prior art. The shelf net 2 can be pulled out of the pickling box 1 by dragging the fixing part on the slide bar 3 with a tool. The circulation box 4 is a circulation device in the prior art and is mainly used to replenish and replace the pickling solution in the pickling box 1 so that there is always pickling solution with a concentration that meets the standard in the pickling box 1.

[0022] The pickling box 1 is provided with a suction pipe 5 for the pickling liquid to enter the circulation box 4. The suction pipe 5 mainly extracts part of the pickling liquid from the bottom of the pickling box 1 for circulation and filtration treatment. At the same time, impurities generated after the titanium alloy is pickled will fall to the bottom of the box and be extracted by the circulation box 4. The suction pipe 5 runs through the bottom of the pickling box 1, and one end protrudes from its outer wall. The outer wall of the suction pipe 5 is provided with multiple leakage holes. One end of the suction pipe 5 is connected to the circulation box 4 through a small pump. The small pump is a liquid pump in the prior art, which is driven by an external power supply and draws the pickling liquid in the pickling box 1 into the circulation box 4.

[0023] The circulation box 4 is provided with a stirring blade 6 for accelerating the flow of the pickling liquid. The stirring blade 6 is a prior art and has been specially treated. Its function is to separate the pickling liquid from impurities and use the vortex to improve the mixing of the newly added pickling liquid and the old pickling liquid. The stirring blade 6 rotates in the circulation box 4 through a rotating shaft. A driving motor is provided on the rotating shaft. The rotating shaft and the driving motor are prior art. The driving motor is driven by an external power supply. The circulation box 4 is provided with a partition plate 7 for reducing the impact of the pickling liquid. The partition plate 7 is used to reduce the impact force of the vortex to prevent the pickling liquid from splashing out of the circulation box 4 due to excessive impact force.

[0024] The circulation box 4 is provided with a plurality of honeycomb filter plates 8 for filtering pickling impurities. The honeycomb filter plates 8 are mainly used for absorbing pickling impurities in the vortex. At the same time, the pickling liquid can improve its purity by passing through the honeycomb filter plates 8. The circulation box 4 is provided with a return groove 9. The return groove 9 and the honeycomb filter plates 8 are in the same plane. The pickling liquid enters the return groove 9 through the honeycomb filter plates 8 and will continuously hit the inner wall of the return groove 9, thereby achieving the effect of reducing the flow of the pickling liquid. The honeycomb filter plates 8 are fixed to the side walls of the return groove 9 by means of a card slot. The return groove 9 is provided with a liquid suction groove 10 for collecting the pickling liquid. The liquid suction groove 10 is used for absorbing the pickling liquid and is also a collection area for the pickling liquid.

[0025] The pickling box 1 is provided with a feeding end 12 for increasing the concentration of the pickling liquid. The feeding end 12 is only used when the concentration of the pickling liquid in the pickling box 1 is insufficient. The pickling liquid is injected into the circulation box 4 through an external connection device. The feeding end 12 is provided with a sensor 13 for detecting the pickling concentration. The sensor 13 is a prior art and mainly detects the concentration of the pickling liquid in the circulation box 4, and at the same time gives feedback and replenishes the pickling liquid in time. The feeding end 12 is provided with an auxiliary pipe for discharging the pickling liquid, and the auxiliary pipe is used to guide the pickling liquid into the circulation box 4.

[0026] A first pump body 11 for guiding the pickling liquid into the pickling tank 1 is symmetrically provided on the circulation box 4. The first pump body 11 sucks the pickling liquid in the suction groove 10 out of the circulation box 4. A second pump body 14 is symmetrically provided on the side wall of the pickling tank 1. The second pump body 14 discharges the sucked pickling liquid into the pickling tank 1, and the second pump body 14 is connected to the first pump body 11 through an auxiliary pipe.

[0027] The working principle of the utility model is as follows: titanium alloy is placed in the shelf net 2 for pickling. After the pickling is completed, the sensor 13 determines whether new pickling liquid is needed according to the concentration of the pickling liquid in the circulation box 4. The newly added pickling liquid can improve the mixing degree with the old pickling liquid through the stirring blade 6. At the same time, the vortex of the stirring blade 6 will accelerate the separation of impurities and the pickling liquid, so that the impurities float on the surface of the pickling liquid and are adsorbed by the honeycomb filter plate 8, thereby improving the purity of the pickling liquid.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
