Description

Technical Field

[0001] The present invention relates to the field of single crystal silicon manufacturing equipment, and in particular to a pipeline cleaning device, a control method and a control system. Background Art

[0002] In the production process of photovoltaic monocrystalline silicon, the single crystal furnace is the main equipment for producing monocrystalline silicon rods. Generally, the silicon crystal is heated to melt by a graphite heater, and the single crystal silicon rod is pulled out by the CZ method. The single crystal furnace will produce a large amount of oxides during operation, and the oxides are discharged to the outside of the furnace through the exhaust pipe of the single crystal furnace. The exhaust system of the single crystal furnace is generally set on the bottom plate of the single crystal furnace. Therefore, the vacuum pipe at the bottom of the single crystal furnace is one of the key equipment for discharging waste gas and residue. Oxides are easy to adhere to the exhaust pipe. When the oxides accumulate to a certain extent, the exhaust pipe will be blocked, which is not conducive to the exhaust of the single crystal furnace during operation, thereby reducing the quality of the silicon rod.

[0003] There are multiple exhaust pipes on the bottom plate of the single crystal furnace to improve the exhaust efficiency of the single crystal furnace and speed up the discharge of oxides and impurities. However, since the pipes are located at the bottom of the furnace, it is very difficult to clean them. In the case of blockage of oxides in the exhaust pipes, brushes, scrapers and other dredging tools are generally used to connect with a pistol drill for cleaning, which is cumbersome. In addition, due to the narrow operating space and incomplete cleaning, the pipes are easily blocked again, affecting the normal operation of the single crystal furnace. Summary of the invention

When the turning point of the pipeline is detected, the telescopic component 4 is stopped from descending, the steering component 8 is controlled to monitor the direction of the turning point, and the extension 5 is started to release the cleaning brush head 6 so that it can pass the turning point smoothly and clean the remaining space of the pipeline. Through the designed cleaning equipment, the inside of the exhaust pipe of the single crystal furnace can be automatically cleaned, and the inside of the narrow and complex pipeline can be cleaned, which can improve the cleaning efficiency.

[0043] The cleaning device has stable support and fixing functions, and can carry the cleaning mechanism 2 and the control system. The main structure is made of high temperature resistant and corrosion resistant materials including but not limited to stainless steel, nickel-based alloy or tungsten alloy, etc., to ensure stability and reliability in the working environment of the single crystal furnace 1.

[0044] The cleaning mechanism 2 includes a telescopic component 4, an extension piece 5 is arranged inside the telescopic component 4, and a cleaning brush head 6 is arranged below the extension piece 5. The cleaning brush head 6 is pushed into the pipe by the telescopic component 4 and the extension piece 5.

[0045] In this embodiment, the telescopic component 4 can be a telescopic rod with a hollow design on the inside, which is connected to a driving motor and driven by a gear or chain to move the telescopic rod axially, thereby realizing the lifting and lowering of the cleaning brush head 6. The extension member 5 is arranged on the inner side of the telescopic component 4. The extension member 5 can be a hose made of silicone rubber material, which has a bendable effect and its material has a certain supporting effect, which can push the cleaning brush head 6 to move inside the pipe.

[0046] The cleaning brush head 6 is connected to the motor 3 , and the motor 3 is installed on one side of the extension member 5 .
