DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a high-efficiency pickling device for cadmium-titanium alloy electroplating pretreatment, comprising:

[0023] A filter box 1 is filled with pickling liquid. A pickling box 2 is installed on the upper end of the filter box 1 and is connected to the filter box 1. A return pipe 13 is installed on the filter box 1. The return pipe 13 is connected to the pickling box 2. The pickling liquid in the pickling box 2 can flow into the filter box 1 through the return pipe 13. However, the liquid pump 8 can only work to meet the amount of pickling liquid required for pickling.

[0024] The material taking mechanism is convenient for taking materials; the material taking mechanism includes a rectangular frame 6 installed on the pickling box 2 and capable of being lifted and lowered, a bracket 3 is installed on the upper end of the pickling box 2, two electric push rods 4 are installed on the bracket 3, the output end of the electric push rod 4 is fixedly connected to the upper end of the rectangular frame 6, and the electric push rod 4 can realize the up and down movement of the rectangular frame 6; a fan 5 opposite to the rectangular frame 6 is installed on the bracket 3, and the fan 5 can blow off the pickling liquid on the surface of the workpiece and the pickling liquid on the mesh placement box 7, making it convenient to remove the mesh placement box 7 and safer. Then the staff can place other mesh placement boxes 7 in the rectangular placement slot 14 and wait for the pickling work. In this way, there is no need to remove the workpiece on the mesh placement box 7 and put a new workpiece, which can improve the efficiency of pickling;

[0025] The inner wall of the rectangular frame 6 is provided with a rectangular placement groove 14, in which a mesh placement box 7 containing cadmium titanium alloy is placed. Two first handles 15 and two second handles 16 are fixed to the mesh placement box 7. The first handle 15 has a larger span. If there are many heavy workpieces inside the mesh placement box 7, the mesh placement box 7 can be removed by passing through the first handle 15 using a forklift or the like. If there are few light workpieces inside the mesh placement box 7, the mesh placement box 7 can be removed manually by holding the first handle 15 or the second handle 16, which is convenient to use.

[0026] The pickling mechanism can circulate the pickling liquid in the filter box 1 and the pickling box 2 and can drive the cadmium titanium alloy to move. The pickling mechanism includes a liquid pump 8 installed on the filter box 1. The liquid inlet end of the liquid pump 8 is installed with a liquid inlet pipe, and the liquid inlet pipe is connected to the filter box 1;

[0027] Among them, a filter screen is installed in the filter box 1, and the filter screen is located between the liquid inlet pipe and the return pipe 13. The pickling liquid can be filtered through the filter screen to prevent impurities from entering the liquid pump 8 and causing damage to it;

[0028] The liquid outlet end of the liquid pump 8 is provided with a liquid outlet pipe 9, a tee pipe 11 is provided on the liquid outlet pipe 9, two delivery pipes 10 are provided on the tee pipe 11, the two delivery pipes 10 are connected to the pickling tank 2 and are symmetrically arranged, and a solenoid valve 12 is provided on each of the two delivery pipes 10, wherein the two solenoid valves 12 are controlled by a relay so that the two solenoid valves 12 work intermittently, similar to a traffic light. For example, the two solenoid valves 12 are alternately switched on and off every 1 minute of operation. This is a PLC technology, which is an existing technology and will not be described in detail.

[0029] Specifically, the workpiece is placed in the mesh placement box 7 and then the electric push rod 4 is started. The electric push rod 4 drives the rectangular frame 6 and the mesh placement box 7 to move downward, so that the mesh placement box 7 and the workpiece are located below the liquid level of the pickling liquid. At this time, the first handle 15 and the second handle 16 are located above the liquid level, and the workpiece can be pickled by the pickling liquid.

[0030] Start the liquid pump 8. When the liquid pump 8 works, it can deliver the pickling liquid in the filter box 1 to the pickling box 2 through the liquid outlet pipe 9, the tee pipe 11 and the delivery pipe 10, so as to realize the circulation of the pickling liquid. When one of the solenoid valves 12 is opened, the pickling liquid is delivered to the pickling box 2 through the delivery pipe 10, so as to realize the flow of the pickling liquid, thereby removing the impurities on the surface of the workpiece after pickling. At the same time, the workpiece can be driven to move in the mesh placement box 7, changing the position between the workpiece and the mesh placement box 7, so as to achieve more comprehensive pickling of the workpiece.

[0031] Then the electromagnetic valve 12 is closed and the other electromagnetic valve 12 is opened, so that the flow direction of the pickling liquid is reversed, driving the workpiece to move again, thereby further improving the pickling effect on the workpiece.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
