Screening machine for preparing quartz sand filter materials for sewage treatment

Abstract

The invention relates to a screening machine, in particular to a screening machine for preparing quartz sand filter materials for sewage treatment. According to the screening machine for preparing thequartz sand filter materials for sewage treatment, multistage screening can be conducted on quartz sand, the blockage phenomenon can be prevented, and collecting can be conducted conveniently. The screening machine for preparing the quartz sand filter materials for sewage treatment comprises a rack and the like. The left side of the inner top of the rack is connected with a driving mechanism. Theupper part of the inner right side of the rack is connected with a screening mechanism. According to the screening machine for preparing the quartz sand filter materials for sewage treatment, the purposes that multistage screening can be conducted on the quartz sand, the blockage phenomenon can be prevented, and collecting can be conducted conveniently are achieved, the purpose of screening the quartz sand is achieved through the arrangement of the driving mechanism and the screening mechanism, and in order to avoid the blockage phenomenon during screening through a filter screen, a first pulling rod is continuously pulled to be loose.

Description

technical field [0001] The invention relates to a screening machine, in particular to a screening machine for preparing quartz sand filter material for sewage treatment. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] Quartz sand filter material is made of natural quartz ore, which is processed through crushing, washing, screening and other processes. It is the most widely used water purification material in the water treatment industry. [0004] Most of the existing screening equipment is a single screening of quartz sand filter material, which cannot accurately measure the indiv...
