Abstract

PURPOSE:To make it possible to prevent the damage of a filter segment caused by accumulation and hardening of fine particles in a raw liquid, by a method wherein piercing perforations mutually communicating filter grooves to the outside of a filtrate guide orifice are provided in spaced relation to a ring shaped filter segment forming a filter body and the interiors of a filter grooves are enlarged. CONSTITUTION:A raw liquid is supplied from a supply port 11a to rotate all filter bodies 2 to a same direction and water in the raw liquid is passed through a filtrate guide orifice 25 and a filtrate chamber 12 from filter grooves 22a to be discharged out of a system from a discharge port 12a. Fine particles in the raw liquid accumulated in the filter grooves 22a are pushed into piercing perforations 26 provided to filter segments 21 when the filter segments of the filter body 2 are protruded into the filter grooves 22a. By this mechanism, filtering pores between fine particles in the filter grooves 21a are re-formed to enable continuous filtration and fine particles are not hardened and fixed because passed through the piercing perforations 26. When a cake is filled between the row formed by two rows of the filter bodies 2 and the raw liquid is not issued from a cake take-out port 11b directly, a lid C is opened to continuously take out the cake from the take-out port 11b.

能となることが判った。Several types of filtration devices are known in which a plurality of two bodies are provided, each having an inner hole in the filter bill placed between two pieces. They are made up of 7 pieces made by stacking 2 pieces and a gap alternately, and the fine particles pushed into the filter groove between each piece by the 7 pieces of the adjacent body are laminated and hardened inside. If you fix it there, the torque of the body will become large and it will not work or)? Sometimes the pieces were damaged. Therefore, as a means to prevent this, the inventor of the present invention attempted to eliminate the layered hardening of fine particles that entered the filter grooves by widening the width between the r pieces of each r body, that is, the width of the merging groove. However, this did not achieve the purpose of hardening and fixation;
It was found that the fine particles could not be removed in the filter grooves, and the fine particles directly came out of the system through the inner hole of the J-shaped pipe, making the filtration effect poor and impossible.
