Energy-saving plate-type micro filter device

Abstract

The invention discloses an energy-saving plate-type micro filter device which comprises a fixed compressing plate (1), filter plate sheets (2), a movable compressing plate (9) and a support column (10). The fixed compressing plate (1) is connected with the support column (10) through an upper guide rod (6) and a lower guide rod (13), the movable compressing plate (9) is arranged between the fixed compressing plate (1) and the support column (10), no less than 2 filter plate sheets (2) are arranged between the fixed compressing plate (1) and the movable compressing plate (9), a gasket is arranged between two adjacent filter plate sheets (2), and the fixed compressing plate (1), the movable compressing plate (9) and the filter plate sheets (2) are fixedly connected through clamping stubs. A filter water inlet (4), a filter water outlet (11), a backflushing water inlet (5) and a backflushing water outlet (14) are arranged on the fixed compressing plate (1). The energy-saving plate-type micro filter device can conduct advanced treatment on sewage, has the advantages of being small in occupation area, high in treatment efficiency and convenient to wash, and additionally is applicable to various pressure fields and wide in application scope.

Description

technical field [0001] The invention relates to filtering equipment, in particular to an energy-saving plate-type micro-filtering equipment, which belongs to the field of water treatment. Background technique [0002] In the prior art, sand filtration is usually used to filter sewage. However, after the equipment has been in operation for a period of time, solid particles will accumulate, and it needs to be shut down for backwashing, interrupting the treatment process, and equipped with backwashing equipment. This water treatment method occupies a large area, has low treatment efficiency and high input costs. [0003] In the advanced treatment of sewage, the advanced treatment part also uses a rotary micro-filter, which can wash or replace the filter cloth during the operation of the equipment, and the filtration accuracy of the equipment can be changed by changing different types of filter cloth. Due to the structure of the equipment, it can only be used in the occasion of...

Problems solved by technology

Due to the structure of the equipment, it can only be used in the occasion of low working pressure. High pressure will damage the filter cloth, and a certain impact will damage the equipment and affect the normal use of the equipment; although the backwashing of the filter cloth and the filter The replacement of the cloth is very convenient, but the equipment needs to be installed in the pool. In order to prevent large-diameter dirt from entering the equipment and damaging the filter cloth, the pool needs to be cleaned regularly, and it is difficult to maintain other parts of the equipment.
