Background
Many filtering devices such as rotary disc vacuum filters, tilting disc filters, etc. suffer from scaling problems of varying degrees, especially the wet slag hopper of a semi-hydrated phosphoric acid rotary disc filter, which causes severe scaling and blockage due to hydration of semi-hydrated phosphogypsum. If the inner surface of the slag bucket cannot be cleaned in time, the volume of the inner cavity of the slag bucket becomes smaller and smaller, and when the inner surface of the slag bucket is serious, the accumulated objects can still climb up to the filter disc along the inner wall of the slag bucket all the time, so that the normal operation and the discharging of the filter are influenced.
The traditional method is to use a pipe type flusher to intermittently or uninterruptedly flush the inner cavity of the slag bucket, the pipe type flusher is usually made of a simple steel pipe, a small spraying hole is drilled at a certain distance under or obliquely below the steel pipe, and sometimes a square water distribution plate is additionally welded at each water outlet in order to enhance the spraying effect.
The tubular flusher reduces the blockage risk of the slag bucket to a certain extent, and has the following disadvantages in practical use:
1. the spraying effect is uneven, the water quantity sprayed by the small holes close to the water inlet end is larger, the water quantity sprayed by the small holes far away from the water inlet end is smaller, the phenomenon is particularly obvious when the washing water quantity is smaller, and the uneven spraying effect is extremely adverse to the guarantee of washing the slag bucket.
2. The main pipe is easy to have scaling and blockage phenomena, the inside of a long and narrow pipeline is difficult to clean, and once the blockage phenomenon is formed inside the pipeline, the flushing effect of the tubular flusher is greatly reduced.
3. The tubular flusher mostly adopts the fixed welding of dispersed otic placode and counts more, and inconvenient person in charge takes out, clears up.
