Presser filter plate frame with self-guided sleeve shaft constant force plunger cylinders

Abstract

The invention discloses a presser filter plate frame with self-guided sleeve shaft constant force plunger cylinders. The presser filter plate frame comprises a bearing plate frame, a moving plate frame and a plurality of plunger cylinders with second-stage self-guided sleeve shafts; each plunger cylinder comprises a cylinder body, a cylinder bottom and a plunger rod; each plunger rod can used as afirst-stage guide shaft and a second-stage guide sleeve seat, a convex rod at each cylinder bottom acts as a second-stage guide shaft, each cylinder body can be used as a first-stage guide sleeve seat, and a process oil channel is arranged in the surrounding border of the bearing plate frame; and an eccentric compensation adjustment ring is arranged at the position, located at the connection of the moving plate frame and the head part of each plunger rod, in a mounting hole in the moving plate frame, the inner ring of the eccentric compensation adjustment ring is elliptical, and the outer ring of the eccentric compensation adjustment ring is circular. By means of the presser filter plate frame with self-guided sleeve shaft constant force plunger cylinders, the parallelism of the bearing plate frame and the moving plate frame in the pressing process can be ensured, the position error of the machining holes of the bearing plate frame and the moving plate frame can be automatically compensated and adjusted by arranging the eccentric compensation adjustment ring, the rigidity of a bearing plate frame steel casting is high, and the bearing plate frame steel casting is unlikely to deform.

Description

technical field [0001] The invention belongs to the technical field of deep sludge dewatering, and relates to deep sludge dewatering equipment, in particular to a press filter plate frame with a self-guiding sleeve shaft constant force plunger cylinder. Background technique [0002] Ultra-high pressure elastic press is a kind of equipment that separates materials from solid and liquid through pressure filtration. It can be widely used in municipal, petrochemical, light industry, chemical fiber, paper, pharmaceutical, leather, food, mineral, metallurgy, electric power, construction and Sewage treatment projects in industries such as agriculture, forestry and water conservancy, especially have unique advantages for the separation of slime. [0003] The filter plate frame of the traditional ultra-high pressure elastic press is to set a number of springs around the fixed plate frame (bearing plate frame) and the movable plate frame, and completely rely on the compression spring ...

AI Technical Summary

Problems solved by technology

The disadvantages of adopting this structure are: the sealing force of the spring body is small when it is initially compressed, and the sealing force between the plate frame and the plate frame is insufficient, which makes it easy to spray mud when entering the mud; the spring is easy to break, causing production to stop, and replacing the spring is time-consuming and laborious ; After the guide shaft between the plate frame and the plate frame is worn or stuck, it will cause misalignment between the plate frame and the plate frame, seal failure, and mud spraying

But there are still the following problems: (1) During the pressing process, the fixed plate frame (bearing plate frame) and the movable plate frame of the filter plate frame must keep moving in parallel

This processing position error will bring great difficulties to the assembly of the bearing plate frame and the movable plate frame, and will increase the frictional resistance of the stainless steel plunger rod during the action
