Embodiment 1

[0016] Such as figure 1 As shown, the combined structure of the compression plate and the spherical pad in the filter press includes a compression plate 1 and a spherical pad 2. The center of the compression plate 1 is concave to form a first groove, and the center of the bottom of the first groove is The concave form has a second groove 3, and the middle surface of the upper end surface of the spherical pad 2 is concavely formed with a hemispherical groove. Wherein, the first groove and the second groove 3 are both circular grooves, and the spherical pad 2 is composed of a hemispherical groove with a concave upper end surface of a cylinder and a perforated hole in the center. The spherical pad 2 of this embodiment is arranged in the first groove and there is a certain distance between the outer side wall and the inner side wall of the first groove, wherein the distance between the outer side wall of the spherical pad 2 and the inner side wall of the first groove is 2 ~4mm, p...

Embodiment 2

[0020] In order to save time and effort when the spherical pad 2 is installed on the pressing plate 1, this embodiment makes the following further limitations on the basis of embodiment 1: the vent hole 4 of this embodiment is a threaded hole, so, in this embodiment During the application, the spherical pad 2 can be hoisted into the first groove by driving the hoisting ring screw into the threaded hole, which is easy to operate and saves time and effort.

Abstract

The invention discloses a composite structure of a keep plate and a ball ring in a pressure filter, comprising a keep plate (1) and a ball ring (2), wherein a central part of the keep plate (1) indents to form a first groove. A bottom center of the first groove indents to form a second groove (3). A central part of an upper end face of the ball ring (2) indents to form a hemispherical groove. The ball ring (2) is arranged inside the first groove, and a gap exists between an outer side wall of the ball ring (2) and an inner side wall of the first groove. The ball ring (2) has an air hole (4) that is vertically arranged and that connects the second groove (3) and the outside. An opening of an upper end of the air hole (4) is located in a center of the hemispherical groove. The invention is simple in overall structure, easy in implementation, and low in costs. The invention is convenient in installation when being applied, saves both time and labor, and plays a role in autocorrection.

Description

technical field [0001] The invention relates to a filter press, in particular to a combined structure of a pressing plate and a spherical pad in the filter press. Background technique [0002] There are two types of connection between the oil cylinder and the pressure plate of the filter press: plane connection and spherical connection. Among them, when the oil cylinder and the pressure plate are connected by a spherical surface, a spherical pad needs to be set on the pressure plate, and the piston of the cylinder through the spherical pad and the cylinder rod contact. At present, when a spherical pad is installed on the pressure plate, a groove is usually arranged at the center of the pressure plate, and the spherical pad is matched with the groove at the center of the pressure plate. When the existing method is used for installation, the spherical pad has no movable margin in the pressing plate during the pressing process, and the automatic correction function cannot be...
