Crude benzene filter with high filtering efficiency

Abstract

The invention discloses a crude benzene filter with high filtering efficiency. The crude benzene filter comprises a filtering casing, wherein a liquid inlet pipe is fixedly communicated onto the top of the filtering casing; a first installing casing is fixedly connected in a position, corresponding to an opening of the liquid inlet pipe, on the top of the inner wall of the filtering casing; the bottom of the filtering casing is fixedly connected with a sealed bottom cover through fixing screw bolts; the left side of the bottom of the sealed bottom cover is fixedly communicated with a liquid outlet pipe. Through the mutual matching of a first installing case, the sealed bottom cover, a second installing case, a filter core tube, a first sealing pad, a second sealing pad, a support plate, aposition limiting rod, a position limiting sleeve, a driving motor, a driving rotating shaft, a support rod, a buffer spring and a scraping plate, impurities adhered onto the crude benzene filter canbe cleaned, so that the filtering efficiency is improved; the inner wall of the filter core tube is kept away from the impurities; the efficient filtering level is always maintained; the filtering efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of crude benzene filtering equipment, in particular to a crude benzene filter with high efficiency. Background technique [0002] Crude benzene is one of the products in the crude gas generated by coal pyrolysis. The benzene series compounds recovered from the coke oven gas after deamination are mainly composed of benzene, which is called crude benzene. Crude benzene is one of the products in the crude gas generated by coal pyrolysis. Crude benzene will carry a large amount of impurities after it is produced, and it needs to be filtered through a crude benzene filter, and the filtered crude benzene is then processed to prevent impurities from affecting the processed benzene and toluene. However, in the existing crude benzene filter, since the filter residue adheres to the inner wall of the filter core, the crude benzene liquid is hindered from passing through the filter core, resulting in a decrease in filt...
