Problems solved by technology

[0002] At present, in the oil fractionation process, the filtered oil needs to be observed in real time for its fineness, which cannot be achieved by ordinary filter presses, and the solid content of the filter cake is low. After each filtration, the residual crystalline oil in the filter chamber will Blocking the filter cloth will affect the next filtration

Embodiment 1

[0009] Embodiment 1: with reference to attached figure 1 . A special filter press for oil fractionation, which includes a filter press frame, the frame contains a thrust plate, a compression plate, a main beam, etc., and is a prior art, which will not be described here. The filter system 6 is located between the pressing plate 7 and the thrust plate 4 in the frame. The filter system 6 is composed of a plurality of diaphragm filter plates stacked and can be compressed or opened. Its structure and working method are prior art, here No narrative. The blowback system 1 is composed of a fluid generating source, a pipeline, and a valve. The outlet of the fluid generating source (air compressor or a nozzle for compressed air source) communicates with the inlet of the pipeline (pipeline), and the outlet of the pipeline passes through the valve and The pipes are respectively connected with the fluid inlets in the upper and middle parts of the pressure plate, and the purpose is to dry...

Embodiment 2

[0011] Embodiment 2: On the basis of Embodiment 1, the fractionation process of the special filter press for oil fractionation, in the process of oil filtration, multiple diaphragms in the filtration system between the compression plate and the thrust plate in the frame Under the action of the hydraulic cylinder, the filter plate compresses the multiple diaphragm filter plates in the filtration system through the compression plate, and then starts the diaphragm pressing system, so that the diaphragm tympanic membrane in the diaphragm filter plate can perform tympanic compression on the formed filter cake, and filter The branched transparent hose in the transparent flow-to-dark flow system of the discharged oil is discharged into the main pipe and then discharged into the container from the main pipe. After the filtration is completed, the washing system washes the filter plate, and then starts the back blowing system to blow off the remaining oil. Dry.

Abstract

The invention relates to a special pressure filter used for oil fractionation and a fractionation process thereof, and the filter comprises a pressure filter frame, a filter system is positioned between the pressure strip and the thrush strip in the frame, the fluid outlet of a reverse flowing system is communicated with the fluid inlets at the upper part and the middle part of the pressure strip, the fluid outlets at the upper part and the middle part of the pressure strip are respectively communicated with the fluid inlet holes of the filter system, the fluid outlets of a diaphragm pressing system are respectively communicated with the pressing cavities of a plurality of diaphragm filter plates in the filter system by flexible pipes, the fluid outlet of a washing system is communicated with the fluid inlet of the thrust strip, the fluid outlet in the thrust strip is communicated with the fluid inlet hole of the filter system, and the fluid inlets of a system of the open stream converting to dark stream are respectively communicated with the fluid outlets at the side parts of a plurality of diaphragm filter plates in the filter system by flexible pipes.

Description

technical field [0001] The invention relates to a patented filter press used for oil fractionation and its fractionation process, which belongs to the field of oil filter press manufacturing. Background technique [0002] At present, in the oil fractionation process, the filtered oil needs to be observed in real time for its fineness, which cannot be achieved by ordinary filter presses, and the solid content of the filter cake is low. After each filtration, the residual crystalline oil in the filter chamber will Blocking the filter cloth will affect the next filtration. Contents of the invention [0003] Design purpose: to avoid the deficiencies in the background technology, to design a filter that can not only observe the color of the oil at any time, but also effectively increase the solid content of the filter cake. Special filter press and fractionation process for oil fractionation. [0004] Design scheme: In order to achieve the above design purpose. 1. The design...
