Embodiment 1

[0011] Embodiment 1: with reference to attached figure 1 . The inlet chuck of the diaphragm filter plate is composed of a ring-shaped chuck with one or two rings and radially seals and tightens the inlet formed by the diaphragm and the filter plate core. The ring chuck is made of plastic or polymer material or metal material. One end of the ring chuck is provided with or without flange. The feed inlet chuck is composed of a ring-shaped chuck 4 and is directly tightened in the feed inlet of the diaphragm, or is composed of a ring-shaped chuck 4 and a ring-shaped support chuck 5, and the ring-shaped chuck 4 is tightened in the diaphragm In the feed inlet, the ring-shaped support chuck 5 is screwed into the ring-shaped chuck 4, and the radial tension force of the ring-shaped chuck 4 is kept constant for the second time. The inner side of the ring-shaped chuck 4 is provided with a threaded button, and the outer bottom has a circle of outward flanging 7, and the ring-shaped sup...

Embodiment 2

[0012] Embodiment 2: On the basis of Embodiment 1, the feed port of the plastic diaphragm filter plate is formed by the chuck of the feed port of the diaphragm filter plate, and the rear part of the flange of the feed port of the diaphragm 2 has a circle or more Platform 8, there is an annular groove in the middle part of the inner side of the feed port of the filter plate 1, and the diaphragm located on both sides of the filter plate, and the boss 8 arranged in one or more circles at the rear of the feed port in the diaphragm is located at the feed port of the filter plate. In the annular groove inside the mouth, the ring-shaped chuck 4 is located in the feed port of the diaphragm and radially tightens the diaphragm feed port on the filter plate, and the ring-shaped support chuck 5 is screwed into the plastic radial chuck. A sealing ring (O-shaped sealing ring) 3 or not is provided between the annular boss between the diaphragm and the filter plate. The production and product...

Abstract

A clamping chuck for the material inlet of diaphragm-filter plate is composed of one or two ring-shaped clamping chucks, which can seal the material inlet consisting of diaphragm and filter plate core. Its advantages are high sealing effect and corrosion resistance, low service life, low cost and no release of filter plate.

Description

Technical field: [0001] The invention relates to a diaphragm filter plate inlet chuck for a diaphragm filter plate and a diaphragm filter plate inlet formed by the diaphragm filter plate inlet chuck, belonging to the field of diaphragm filter plate manufacturing. Background technique: [0002] At present, the feed ports of split combined plastic diaphragm plates on the market all use metal clamps (see attached figure 2 ) fastening, due to the inherent poor corrosion resistance, heavy weight and high cost of the metal itself, especially the higher price of special metals, it seriously restricts the popularization and application of split combined plastic diaphragms. Invention content: [0003] Design purpose: To avoid the deficiencies in the background technology, through the improvement of the structure of the filter plate and the diaphragm, design a collet of the feed port of the diaphragm filter plate and the feed port of the diaphragm plate that can match it. [0004] ...
