Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, specifically to a mixing pipeline device for improving the uniformity of tank cleaning solution. Background Technology

[0002] In the production of solar cells, the uniformity of the chemical solution has a significant impact on the photoelectric conversion efficiency, stability, and lifespan of the cells. For example, in processes such as texturing, etching, and polishing, uneven mixing of the chemical solution can lead to inconsistent surface treatment of silicon wafers, resulting in large performance dispersion and abnormal appearance of the cells. Currently, traditional chemical solution mixing mainly uses circulating pumps for regulation. The conveying pipelines are mostly linear structures, and the chemical solution relies solely on its own laminar flow within the pipeline, resulting in poor mixing. Excessive circulation flow can easily cause abnormalities in the texturized / etched surfaces, making it difficult to meet the requirements of high-precision solar cell production. Although some existing technologies use static mixers or stirring devices to improve the mixing effect, these suffer from problems such as complex structures, easy chemical residue, and difficulty in adapting to the rapid switching and continuous delivery of multiple chemical solutions in solar cell production.

[0003] Therefore, there is an urgent need for a simple, efficient, and suitable liquid mixing device for solar cell manufacturing processes. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a mixing pipeline device for improving the uniformity of cleaning solutions in tank-type applications. By designing the pipeline as a spiral structure and incorporating symmetrical turbine blades, the turbulent mixing of the solution during transport is enhanced, significantly improving the uniformity of the solution and meeting the high-precision production requirements of solar cells.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mixing pipeline device for improving the uniformity of tank cleaning solution, comprising a pipeline body, an inlet at one end of the pipeline body and an outlet at the other end, a spiral premixing ridge on the inner side wall of the pipeline body, and a turbulence module in the middle of the pipeline body.

[0006] As a further improvement to the above technical solution:

[0007] The turbulence module includes symmetrically distributed turbulence fans, each of which is connected to the inner wall of the pipe body via a bracket.

[0008] The spoiler fan includes a positioning shaft connected to the bracket, a rotating sleeve is provided on the positioning shaft, and spoiler blades are provided on the side wall of the rotating sleeve.

[0009] The number of the baffles is multiple and they are evenly distributed along the circumference of the rotating sleeve. Each baffle has an angle of 30-60 degrees with the axial direction of the pipe.

[0010] The distance between the two aforementioned baffles is 2-5 times the diameter of the duct body.

[0011] The feed inlet is connected to the conveying pump, and pressure sensors are installed at both the feed inlet and the discharge outlet.

[0012] The spiral premixed ridges are numerous and evenly distributed along the inner wall of the pipe body.

[0013] The outer side of the pipe body is provided with a protective pipe, and a supporting rib is provided between the protective pipe and the pipe body.

[0014] The beneficial effects of this utility model embodiment are as follows: The mixing pipeline device for improving the uniformity of tank cleaning solution includes a pipeline body, one end of which is provided with an inlet and the other end with an outlet. The inlet is connected to a delivery pump. Pressure sensors are provided at both the inlet and outlet. Spiral premixing ridges are provided on the inner side wall of the pipeline body. A turbulence module is installed in the middle of the pipeline body. Compared with traditional complex mixing devices, this solution achieves the mixing function through innovative design of the pipeline structure. There are no complex moving parts, reducing equipment costs and maintenance difficulty. The pressure sensors monitor the pipeline pressure in real time to ensure the safe and stable operation of the device and avoid production disruptions caused by blockages. It can also be adapted to different flow rates and characteristics of the solution by changing the distance between the two turbulence fans or the tilt angle of the turbulence blades, meeting the diverse needs of production.

[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] like Figure 1 As shown, the mixing pipeline device for improving the uniformity of the cleaning solution in the tank in this embodiment includes a pipeline body 1. One end of the pipeline body 1 is provided with an inlet 2 and the other end is provided with an outlet 3. The inlet 2 is connected to a conveying pump. Pressure sensors 10 are provided at both the inlet 2 and the outlet 3. Spiral premixing ribs 4 are provided on the inner side wall of the pipeline body 1. A turbulence module is installed in the middle of the pipeline body 1.

[0023] like Figure 2 As shown, the turbulence module includes symmetrically distributed turbulence fans 5, each of which is connected to the inner wall of the pipe body 1 via a bracket 6.

[0024] like Figure 3 As shown, the spoiler fan 5 includes a positioning shaft 7 connected to the bracket 6, a rotating sleeve 8 is provided on the positioning shaft 7, and spoiler blades 9 are provided on the side wall of the rotating sleeve 8.

[0025] like Figure 4 As shown, there are multiple turbulence blades 9, which are evenly distributed along the circumference of the rotating sleeve 8, and each turbulence blade 9 has an angle of 45 degrees with the axial direction of the pipe.

[0026] like Figure 2 As shown, the distance between the two spoiler fans 5 is 5 times the diameter of the pipe body 1.

[0027] like Figure 4-5 As shown, there are multiple spiral premixed ridges 4, which are evenly distributed along the inner wall of the pipe body 1.

[0028] like Figure 2 As shown, a protective pipe 11 is provided on the outside of the pipe body 1, and a supporting rib 12 is provided between the protective pipe 11 and the pipe body 1.

[0029] The working principle of this solution is as follows: the liquid medicine enters the pipeline body 1 through the inlet 2 via a delivery pump. Under the action of the spiral premixing ribs 4, the liquid medicine is premixed. When the liquid medicine moves to the turbulence module, the two turbulence fans 5 rotate in opposite directions, which can push the liquid medicine in the forward and reverse directions, thereby improving the uniformity of the liquid medicine mixing. Compared with traditional complex mixing devices, this solution achieves the mixing function through innovative design of the pipeline structure. There are no complex moving parts, which reduces equipment costs and maintenance difficulty. The pressure sensor monitors the pipeline pressure in real time to ensure the safe and stable operation of the device and avoid production disruptions caused by blockages. It can also be adapted to liquid medicines with different flow rates and characteristics by changing the distance between the two turbulence fans or the tilt angle of the turbulence blades, thus meeting the diverse needs of production.
