Description

A kind of sewage disposal lime block screening installation

Technical field

The present invention is a kind of sewage disposal lime block screening installation, belongs to lime block screening installation field.

Background technology

B.C. 8th century Greeks have been used for building, and China also begins to use lime in B.C. 7th century.So far stone Ash is still widely used construction material.Lime has quick lime and white lime (i.e. calcium hydroxide), by its content of magnesia (with 5% is limited) and calcareous lime and magnesium lime can be divided into.Since its feed distribution is wide, simple production process is of low cost.Stone Ash has stronger alkalinity, at normal temperatures, can be with the active silica or active oxidation reactive aluminum of glassy state, and generating has the hydraulicity Product, generate it is cementing.Therefore, raw material important in lime or building material industry.

Lime block is chiefly used in building material industry, usual in use, it is generally necessary to people remove screening lime manually Block, it is not high enough and screen not careful to lead to screen lime block efficiency, has been directed to this in the market and devises proprietary screening and sets It is standby, but there are one disadvantages for this equipment, that is,：Be not suitable for sewage disposal, screened using this kind of equipment, screening is surplus Remaining lime block, which needs to carry out additional processing, could carry out sewage disposal, increase workload, and working efficiency is low.

Invention content

In view of the deficienciess of the prior art, it is an object of the present invention to provide a kind of sewage disposal lime block screening installation, Remaining lime block is screened with lime block screening installation to solve sewage disposal to need to carry out additional processing that sewage could be carried out Processing increases workload, ineffective problem.

To achieve the goals above, the present invention is to realize by the following technical solutions：A kind of sewage disposal lime Block screening installation, structure include lime block input bucket, shell, side extension support column, damping spring, supporting rack, vibration motor, Lime block screening plant, lime block input bucket are fixedly mounted on cover top portion side and run through cover top portion panel It is connected with lime block screening plant, the lime block screening plant is installed in the shell, and the side extends support column and sets There are four and be in that symmetrical structure is set in shell side and is welded with shell machinery, four branch at the top of the supporting rack two-by-two Damping spring is mounted on strut, the both ends of the damping spring extend support column with side respectively, supporting rack is mechanically connected, The vibration motor is fixedly mounted on outer casing bottom；
