Technical scheme: filter candle, adopt sweat soldering between the coupling head of candle pipe, UNICOM's head and the candle pipe; Adopt sweat soldering between UNICOM's head, tail welding block and the outer tube; Adopt Bolt Connection to form between tail welding block and the backstay coupling block, connect sealing by sealing ring and clip realization between candle pipe and the filter cloth cover.

The utility model is compared with background technology, and the one, novel structure, uniqueness, simple; Two are to use corrosion resistant plastic material, in light weight, the intensity height, and cost is low, can carry out Separation of Solid and Liquid in adverse circumstances such as deep-etching; The 3rd, overall structure is firm, long service life; The 4th, it is convenient to unload cake.
