Description

Filter plate handle of filter press

Technical Field

The utility model relates to a pressure filter field especially relates to a pressure filter plate handle.

Background

A mechanical device for dialyzing liquid by applying a certain pressure to a subject by using a special filter medium in a filter press is a common solid-liquid separation device. The method is applied to chemical production at the beginning of the 18 th century, and is still widely applied to the industries of chemical industry, pharmacy, metallurgy, dye, food, brewing, ceramics, environmental protection and the like until now. The filter press is composed of a frame, a pressing structure and a filtering mechanism, wherein the frame is a basic component of the filter press, two ends of the frame are provided with a thrust plate and a pressing head, the thrust plate and the pressing head are connected by crossbeams on two sides, and the crossbeams are used for supporting the filter plate, the filter frame and the pressing plate. The filter mechanism comprises filter plates, filter frames, filter cloth and squeezing diaphragms, wherein the two sides of each filter plate are coated by the filter cloth, and when the squeezing diaphragms need to be configured, one group of filter plates comprise diaphragm plates and side plates. The two sides of the base plate of the diaphragm plate are coated with rubber diaphragms, the outer sides of the diaphragms are coated with filter cloth, and the side plate is a common filter plate. The material enters each filter chamber from the material-passing holes on the thrust plate, solid particles are trapped in the filter chambers because the particle size of the solid particles is larger than the aperture of the filter medium (filter cloth), and filtrate flows out from the liquid outlet holes below the filter plates. When the filter cake needs to be squeezed, compressed air or steam can be introduced from a washing port besides being squeezed by a diaphragm, and the water content in the filter cake is flushed by airflow so as to reduce the water content of the filter cake. Because the filter pressing work belongs to 24-hour work system, the working time is longer, the handle screw of the filter plate is loosened, the filter plate is easy to damage, the workshop loss is larger, and in the filter plate replacing process, the filter plate handle belongs to the lifting position, and the filter plate is easy to fall off to cause personnel injury. The Chinese utility model with publication number CN104906846B discloses a novel simple filter plate handle for a filter press, which comprises a handle body, the upper end of the handle body is provided with a first connecting hole, the lower end of the handle body is provided with a second connecting hole, the right end of the handle body is provided with a hand inserting hole which is a waist-shaped hole and is inclined downwards from left to right, the inclination angle is 30-60 degrees, the lower end of the handle body is integrally provided with a connecting lug, the lower end surface of the connecting lug is provided with a threaded hole, a connecting screw rod is connected in the threaded hole, the lower end of the connecting screw rod is welded with a sliding block, an oil storage cavity is arranged at the position of the handle body right above the connecting lug, the upper end of the oil storage cavity is provided with a lubricating oil filling hole, this lubricating oil tank filler hole one end articulates there is sealed flip, the oil storage chamber lower extreme is provided with the oil outlet, the fixed governing valve that is provided with in oil outlet outer end. Although this technical scheme is favorable to manual pulling the filter plate, and also can motor-driven pulling filter plate, its handle body passes through two screws to be fixed on the filter plate, because filter-pressing work belongs to 24 hours work system, operating time is longer, and the handle screw of filter plate is not hard up, and is difficult for noticing, has the potential safety hazard.
