[0024] The technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Please refer to Figures 1-3 , the semiconductor material mixing and stirring transfer device includes a moving frame 10 with a universal wheel installed at the bottom and a mixing kettle body 1 fixedly installed on the moving frame 10. The inner liner of the mixing kettle body 1 is made of polytetrafluoroethylene material, which can avoid the introduction of metal impurities and improve product production yield.

[0026] The mixing kettle body 1 is provided with a pneumatic stirrer 2 and a flushing nozzle 3. The flushing nozzle 3 is a pneumatic rotary spray head, the top seat of which is fixed on the top wall of the mixing kettle body 1, and the bottom extends into the mixing kettle body 1. A pneumatic pump 4 is also installed on the moving frame 10. The pneumatic pump 4 is intermittently connected with the pneumatic stirrer 2 and the flushing nozzle 3. Specifically, the outlet of the pneumatic pump 4 is connected with the air inlet of the pneumatic stirrer 2 and the air inlet of the flushing nozzle 3 through detachable conveying pipes.

[0027] During mixing and stirring, the conveying pipe connects the pneumatic pump 4 with the pneumatic stirrer 2. The pneumatic pump 4 is used to provide compressed air to the pneumatic stirrer 2. The compressed air is used as a power source to drive the pneumatic motor or pneumatic cylinder in the pneumatic stirrer 2, so as to drive the stirring shaft of the pneumatic stirrer 2 extending into the mixing kettle body 1 to rotate. When the stirring shaft rotates, the stirring blades fixed on the stirring shaft drive the materials in the mixing kettle body 1 to mix and stir.

[0028] When the materials are stirred and discharged, the conveying pipe connects the pneumatic pump 4 with the flushing nozzle 3. The pneumatic pump 4 provides compressed air to the flushing nozzle 3. The compressed air enters the power conversion mechanism such as the pneumatic motor or pneumatic cylinder in the flushing nozzle 3 through the air inlet of the flushing nozzle 3, and converts the pressure energy of the compressed air into mechanical energy to provide power for the rotation of the flushing nozzle 3. For example, in some small pneumatic rotary spray heads, the compressed air drives the piston in the pneumatic cylinder to move, and drives the bottom head of the pneumatic rotary spray head to rotate through the transmission mechanism in the flushing nozzle 3. The flushing nozzle 3 is provided with spray nozzles at the top, middle and bottom of the head in the mixing kettle body 1. The spray nozzles at the top are directed towards the top wall of the mixing kettle body 1, the spray nozzles at the middle are directed towards the side wall of the mixing kettle body 1, and the spray nozzles at the bottom are directed towards the bottom wall of the mixing kettle body 1.

[0029] The flushing nozzle 3 is further connected with a cleaning liquid supply device. When the cleaning liquid with a certain pressure passes through the spray nozzles of the flushing nozzle 3, the sprayed cleaning liquid forms a specific spray range under the rotation of the flushing nozzle 3, so as to realize uniform spraying in a large area, and the cleaning is more thorough and efficient.

[0030] Compared with the traditional mechanical pump, the pneumatic pump 4 has a smaller size. The standard configuration of the mechanical pump is 380V, and the conversion needs to be performed during operation. The pneumatic pump 4 does not need this operation.

[0031] Please refer to Figures 1-2 , the mixing, stirring and transferring device for semiconductor materials, the moving frame 10 is further fixedly provided with a filter 5 connected in series with the pneumatic pump 4.

[0032] The outlet of the filter 5 is connected with the inlet of the pneumatic pump 4, and is used to filter the air entering the pneumatic pump 4 to avoid impurities entering. A pressure gauge 6 is connected in series between the pneumatic pump 4 and the filter 5, and the pressure gauge 6 is fixed on the moving frame 10.

[0033] Referring to Figure 1 , the semiconductor material mixing and stirring transfer device, the mixing kettle body 1 top wall is further provided with exhaust valve 7, discharge port 8, respectively for the discharge of excess gas and material into, discharge port 8 can be simultaneously connected to multiple material conveying pipeline.

[0034] Referring to Figure 1 , the semiconductor material mixing and stirring transfer device, the mixing kettle body 1 top wall is further provided with transparent observation window, convenient and intuitive observation of the mixing of the material;

[0035] And the transparent observation window outside cover has light shield 9, when not observing, close the light shield 9 and cover the transparent observation window.

[0036] It is worth mentioning that the pneumatic pump 4, filter 5, pneumatic stirrer 2, pneumatic rotary shower head specific model mentioned in the embodiment, and its matching power supply and control switch can also be provided by the manufacturer, the circuit and electronic components and modules are all prior art, and those skilled in the art can realize without unnecessary description.

[0037] Referring to Figures 1-2 , the semiconductor material mixing and stirring transfer device, the moving frame 10 has a handrail.

[0038] Referring to Figures 1-2 , the semiconductor material mixing and stirring transfer device, the mixing kettle body 1 top has a top cover that can be opened and closed, the pneumatic stirrer 2 and the flushing shower head 3 are installed on the top cover, and the discharge port 8, the exhaust valve 7 and the transparent observation window are also located on the top cover.

[0039] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
