Description

Technical Field

[0001] This utility model relates to the field of rotary filter technology, and more specifically, to a rotary filter that can be cleaned both internally and externally. Background Technology

[0002] To control the vacuum level during the crystal growth process of semiconductor crystal growth equipment, a vacuum pump is required to perform a vacuuming operation. However, oxide dust entering the vacuum pump can damage it. Therefore, a filtration system must be added before the vacuum pump to protect its normal operation. The filter element is an important component of the filtration system and must be cleaned to ensure its filtration efficiency.

[0003] In previous studies on filter element cleaning, the filter elements of the filtration system could only be cleaned after the furnace was shut down. During the filtration process, oxides would adhere to the filter elements, which would accumulate over time and affect the filtration efficiency of the filter elements. In addition, the filter element disassembly operation was troublesome and the disassembly process might damage the filter elements. Utility Model Content

One end of the upper cleaning liquid inlet pipe 222 is installed at one end of the upper tee control connector 221. The lower end of the upper tee control connector 221 is located on both the inner and outer walls of the upper conveying pipe 213. The lower control connector 228 is installed on both the inner and outer walls of the lower conveying pipe 214. The wastewater discharge tank 223 has two sets of openings. Furthermore, two sets of sewage discharge tanks 223 are respectively opened on the inner and outer walls of the two sides of the rotary filter core body 212. The waste collection and protection chamber 224 is installed inside the lower outer wall of the rotary filter core body 212. The inner wall of the waste collection and protection chamber 224 is provided with a water inlet tank. One end of the first diversion discharge pipe 226 and the second diversion discharge pipe 227 are respectively installed on the outer walls of the two sides of the waste collection and protection chamber 224.

After the upper conveying pipe 213 and the lower conveying pipe 214 are closed, water is injected through the upper cleaning liquid injection pipe 222 at the upper end. The upper cleaning liquid injection pipe 222 injects cleaning water into the rotating filter element body 212 to perform backwash cleaning. After the rotating filter element body 212 is cleaned, it is discharged through the sewage discharge trough 223 at the lower end of the rotating filter element body 212. After being discharged from the sewage discharge trough 223, it enters the collection chamber 225 and is discharged through the first diversion discharge pipe 226 and the second diversion discharge pipe 227 set on the side of the two sets of collection chambers 225. The device greatly enhances the convenience of cleaning and maintenance by using cleaning water backwashing.
