Space and thickness adjustable frame type filter plate

Abstract

The invention relates to the technical field of filter presses of filtering equipment, and further relates to a space and thickness adjustable frame type filter plate. A frame and the filter plate are arranged in an alternated manner, lifting eye bolts are respectively mounted on the middle positions of the tops of the frame and the filter plate, drilled square head bolts are respectively mounted in screw holes on the two sides of the filter plate and the frame, a round hole in the side surface of a cap of the drilled bolt is axially horizontal, a thread rope is threaded into the round holes in the side surfaces of the caps of the drilled bolts, a screw with a handle is mounted at the top of the cap of the drilled bolt, the thread rope is pressed, and the frame type filter plates are connected. The number and the thickness of the frame type filter plate are increased, decreased or changed by loosening the screw with the handle and regulating the length of the thread rope, the space and thickness adjustable frame type filter plate is simple in structure and convenient in dismounting, time for dismounting is greatly reduced, the filtering requirements for various materials are conveniently dealt with, and the liquid filtering efficiency is maximized.

Description

technical field [0001] The invention belongs to the field of filter presses of filter equipment, and more specifically relates to a plate-frame filter plate with adjustable spacing and thickness. Background technique [0002] Filter press is a kind of sewage filtration device commonly used in industrial production. It is an important equipment to realize solid-liquid separation of sewage. The plate and frame filter plate is the main filter element of filter press. Due to economic development, it is suitable for The material filtered by the plate and frame filter plate is gradually increasing. When the plate and frame filter plate is filtering, the material enters the filter chamber in the plate frame, and the filtrate is discharged from the outlet hole of the filter plate through the feed pressure, and the filter cake is formed in the plate frame. The composition of the frame filter plate is that a filter plate and a plate frame are combined into a set to filter. The materia...

AI Technical Summary

Problems solved by technology

[0003] The plate-and-frame filter plate has deficiencies in field use. There are many types of materials and each has its own characteristics. When some materials are filtered, the filter chamber is easily filled with filter cakes in a short time, resulting in the failure of the machine to clear the filter cakes. The frequency increases, which affects the filtration efficiency. When some materials are filtered, the amount of filtrate discharged is small, and the filtration efficiency is low. It is necessary to disassemble and replace a larger filter chamber or a large number of plate and frame filter plates to process the corresponding materials. The filtrate efficiency is maximized, but the disassembly and assembly of the connection device connecting the plate and frame filter plate is troublesome, and a lot of time is required for disassembly and assembly, which affects the production efficiency
