[0002] The scroll disc mainly includes a base and scroll part, the scroll part is arranged at the top end of the base, three lugs are arranged on the base along the circumference, a through hole is arranged on each lug, and a plurality of grooves are arranged at the bottom end of the base, and the contour requirement of the scroll disc after processing is high. After the scroll disc is processed, surface treatment needs to be carried out, and the specific treatment mode is as follows: a plurality of scroll discs are fixed on the conductive plate, the scroll disc is immersed in the sulfuric acid solution of the oxidation tank body, then the scroll disc is electrified by the conductive plate, sulfuric acid is used as the cathode, and the scroll disc is used as the anode, and oxidation-reduction reaction is carried out, so that a plating layer is formed on the surface of the scroll disc. In addition, the bottom of the oxidation tank body is provided with a gas pipe for blowing gas towards all the scroll discs, so as to promote the flow of the sulfuric acid solution at the scroll disc. However, with the oxidation-reduction reaction, the flow and concentration of the sulfuric acid solution at different parts of the scroll disc are quite different, resulting in uneven thickness of the plating layer, so that the contour of the scroll disc cannot meet the requirements. SUMMARY

[0003] In view of the defects in the prior art, the utility model aims to provide a scroll disc plating layer surface treatment blowing device to solve the technical problem that the contour of the scroll disc does not meet the requirements due to uneven thickness of the plating layer after surface treatment.

[0004] To solve the above technical problems, the utility model provides a scroll disc plating layer surface treatment blowing device, which comprises an oxidation tank body, a connecting plate, an air inlet pipe, a plurality of first air outlet pipes and a plurality of conductive seats, the connecting plate is arranged in the oxidation tank body, the plurality of conductive seats are connected to the front end of the connecting plate in a spaced distribution mode, each conductive seat is connected to a scroll disc, the connecting plate is provided with an air channel, the air inlet pipe is connected to the connecting plate and communicates with the air channel, each first air outlet pipe is connected to the connecting plate and communicates with the air channel, a plurality of first air outlet pipes are horizontally arranged below each conductive seat, and each first air outlet pipe is arranged obliquely upwards and faces the scroll disc on the conductive seat.

[0005] With the above structure, the air blowing device for surface treatment of vortex disk coating of this utility model has the following advantages: compressed gas is introduced by the air inlet pipe and blown out from each first air outlet pipe through the air passage. Several horizontally distributed first air outlet pipes are correspondingly arranged below each vortex disk. The gas blown out by the first air outlet pipe flows towards the vortex disk and can cover the entire vortex disk as much as possible. It will also flow from bottom to top through the entire vortex disk, promoting the flow of sulfuric acid solution near the entire vortex disk. This allows the sulfuric acid solution to flow fully inside and outside the vortex part of the vortex disk, making the flow state and concentration of sulfuric acid solution near the vortex disk more uniform. The coating thickness after surface treatment of the vortex disk is more uniform, and the contour of the vortex disk meets the requirements.

[0006] As an improvement, several second air outlet pipes are connected to the left and right side walls of the connecting plate. Each second air outlet pipe is connected to the air passage. The second air outlet pipes are distributed vertically and each second air outlet pipe is set obliquely upward. With this structure, the second air outlet pipes play an auxiliary role in blowing air, further promoting the flow of sulfuric acid solution near the vortex disk and improving the uniformity of the coating after the surface treatment of the vortex disk.

[0007] As an improvement, each first and second exhaust pipe is equipped with a flared end. This structure expands the blowing range by setting the flared end, allowing the gas to flow through the entire vortex disk and drive the sulfuric acid solution to flow, resulting in a more uniform coating thickness after the vortex disk surface treatment.

[0008] As an improvement, the connecting plate is provided with several through holes; this structure allows the sulfuric acid solution to flow to the vortex disk through the through holes, preventing the connecting plate from blocking the sulfuric acid solution.

[0009] As an improvement, a pressure regulating valve is connected in series on the intake pipe; this structure makes the gas blown out of the first exhaust pipe more stable, thereby improving the uniformity of the coating after the surface treatment of the scroll plate.

[0010] As an improvement, the oxidation tank is equipped with a first main gas pipe in the shape of a rectangular frame. The first main gas pipe has several gas outlets facing the connecting plate. The first main gas pipe is connected to a second main gas pipe. One end of the second main gas pipe is located outside the oxidation tank and is equipped with a gas inlet. With this structure, air is blown from the gas outlet of the first main gas pipe to replenish sulfuric acid solution to the connecting plate, thereby improving the uniformity of the coating after the surface treatment of the vortex disk.

[0011] As an improvement, a conductive frame is installed on the oxidation tank, and a connecting plate is connected to the conductive frame.

[0012] As an improvement, the top of the oxidation tank is connected to two connecting blocks, one on the left and one on the right. Each connecting block has a limiting groove at its top, and the width of the limiting groove gradually decreases from top to bottom. The conductive frame has two limiting parts on the left and right that match the shape of the limiting groove. The two limiting parts are respectively engaged in the two limiting grooves. With this structure, the conductive frame can be directly separated from the connecting blocks upwards. Moreover, the limiting groove and the limiting parts enable the conductive frame to be accurately and stably fixed on the oxidation tank. It is not only simple in structure but also convenient to connect. Attached Figure Description

The connecting plate 2 is disposed inside the oxidation tank 1. Specifically, a conductive frame 13 is mounted on the oxidation tank 1, and the connecting plate 2 is connected to the conductive frame 13. Figure 1 As shown, the top of the oxidation tank 1 is connected to two connecting blocks 14 on the left and right. Each connecting block 14 has a limiting groove 15 at its top. The width of the limiting groove 15 gradually decreases from top to bottom. Here, the width refers to the width of the limiting groove 15 in the front-back direction. In this embodiment, the cross-section of the limiting groove 15 is an isosceles trapezoid. The conductive frame 13 is provided with two limiting parts 16 on the left and right with shapes matching the limiting groove 15. That is to say, the cross-section of the limiting part 16 is also an isosceles trapezoid. The two limiting parts 16 are respectively engaged in the two limiting grooves 15. The lifting mechanism drives the conductive frame 13 to lift and lower, which can realize loading and unloading.

[0020] likeFigure 2 As shown, several conductive seats 5 are distributed at intervals on the front end of the connecting plate 2. Specifically, the conductive seats 5 are distributed in a matrix on the front end of the connecting plate 2. In this embodiment, the front end of the connecting plate 2 is provided with three rows and two columns of conductive seats 5. Each conductive seat 5 is connected to a vortex disk. The connecting plate 2 is provided with an air passage. The air inlet pipe 3 is connected to the connecting plate 2 and communicates with the air passage. The air inlet pipe 3 is connected to the upper end face of the connecting plate 2, and a pressure regulating valve 9 is connected in series on the air inlet pipe 3. Each first air outlet pipe 4 is connected to the connecting plate 2 and communicates with the air passage. Several horizontally distributed first air outlet pipes 4 are provided below each conductive seat 5, so that the first air outlet pipes 4 can basically cover the vortex disk in the horizontal direction. Each first air outlet pipe 4 is obliquely upward and faces the vortex disk on the conductive seat 5. Most of the first air outlet pipes 4 are located on the front end face of the connecting plate 2, while the bottom row of first air outlet pipes 4 is located at the bottom end of the connecting plate 2.

[0021] In addition, such as Figure 2 As shown, several second air outlet pipes 6 are connected to both the left and right side walls of the connecting plate 2. Each second air outlet pipe 6 is connected to an air passage. The second air outlet pipes 6 are distributed vertically and are all angled upwards. Similarly, at least one second air outlet pipe 6 is provided next to each vortex plate, and as shown... Figure 2 and Figure 4 As shown, each first air outlet pipe 4 and each second air outlet pipe 6 has a flared end 7 at its outlet. Figure 2 As shown, the connecting plate 2 has several through holes 8.

[0022] like Figure 1 and Figure 3 As shown, the oxidation tank 1 is provided with a first main gas pipe 10 in the shape of a rectangular frame. The first main gas pipe 10 is provided with a number of gas outlets 17 facing the connecting plate 2. The gas outlets 17 are only provided on the two long sides of the first main gas pipe 10 and are distributed at equal intervals along the left and right directions. The first main gas pipe 10 is connected to a second main gas pipe 11. One end of the second main gas pipe 11 is located outside the oxidation tank 1 and is provided with a gas inlet 12.

[0023] Air is drawn in through the intake pipe 3 and compressed gas is blown out through the air passage from each first exhaust pipe 4. Several horizontally distributed first exhaust pipes 4 are correspondingly arranged below each vortex disk. The gas blown out by the first exhaust pipes 4 flows towards the vortex disk and can cover the entire vortex disk as much as possible. It will flow from bottom to top across the entire vortex disk, promoting the flow of sulfuric acid solution near the entire vortex disk. This allows the sulfuric acid solution to flow fully inside and outside the vortex part of the vortex disk, making the flow state and concentration of sulfuric acid solution near the vortex disk more uniform. The coating thickness after the surface treatment of the vortex disk is more uniform, and the contour of the vortex disk meets the requirements.
