Embodiment Construction

[0014] Such as figure 1 , figure 2 As shown, the present invention includes a diaphragm sheet 1 and a core plate 3 . The two sides of the core plate 3 are respectively equipped with pressure-resistant diaphragms 5, and the surroundings are connected by screws 2 and nuts 4. Elastic sealing elements 6 and 7 are respectively installed between the diaphragm 5 and the core plate 3 to ensure the tightness of the pressing fluid. seal; figure 2 Middle 9 is diaphragm clamp, fixes with screw 10.

[0015] The end faces of the screws 2 and nuts 4 are blocked with plastic covers or plastic welding 8.

[0016] The material of the diaphragm 1 is polypropylene, polypropylene elastomer, hard rubber, polyethylene or fluoroplastic.

[0017] The material of the core plate is metal, polypropylene, polyethylene or fluoroplastic.

[0018] The size of the membrane filter plate is 250-3000 mm, the number of fixing screws 2 and nuts 4 is 2-100, and the core plate 3 can be metal or non-metal.

Abstract

The invention discloses a filter press membrane filter plate, comprising a diaphragm and a core board, wherein a pressure diaphragm piece is arranged at each side of the core board; the periphery of the core board is formed through the connection of screws and nuts; an elastic sealing element is arranged between the diaphtagm and the core board; the end faces of the screws and nuts are sealed by plastic cover or plastic welding. The filter press membrane filter plate has the advantages of no use of specialized welder, small investment, changeable diaphragm, high intensity, higher pressure, longer service life, and higher utilization strength.

Description

technical field [0001] The invention relates to a solid-liquid separation device, in particular to a diaphragm filter plate of a filter press. Background technique [0002] Common filter press diaphragm filter plates are manufactured by the following methods: the diaphragm and the core plate are fused together by heat and compression. The existing problems are high manufacturing cost, high rejection rate, poor sealing performance and high operating cost. The diaphragm and the core board are fitted together through the slots of the core board, but the existing problem is that the strength of the core board is weakened and easily damaged. Contents of the invention [0003] The purpose of the present invention is to provide a diaphragm filter plate of a filter press, which is connected with a diaphragm sheet and a core plate by fasteners. [0004] The technical scheme adopted in the present invention is: [0005] The invention includes a diaphragm sheet and a core plate. B...
