摘要

格柵機(jī)主要用于城市污水、造紙、石油化工、紡織、印染、食品加工、制藥等廢水處理的前級(jí)粗渣攔截處理中，分離污水中懸浮物、漂浮物。廢水通過(guò)格柵機(jī)攔截處理，既可保護(hù)水泵，還可保護(hù)后續(xù)污水處理中管道不被堵塞。
格柵是污水處理的第一道工序，主要是攔截進(jìn)廠(chǎng)污水中粗大的漂浮物和雜物，以保證后續(xù)處理設(shè)施能正常運(yùn)行的一種預(yù)先、處理方法。廢水經(jīng)過(guò)格柵機(jī)攔截處理，能夠除去廢水中的漂浮物或者部分懸浮狀態(tài)的污染物，減輕廢水的腐化程度和后續(xù)處理工藝的負(fù)荷。
本次設(shè)計(jì)，該學(xué)生查閱了大量資料，對(duì)于各種機(jī)械格柵做了充分的比較，并且利用所學(xué)的知識(shí)設(shè)計(jì)了鉤耙式自動(dòng)機(jī)械格柵機(jī)，包括工作機(jī)構(gòu)，傳動(dòng)系統(tǒng)，柵面，柵條等機(jī)構(gòu)的設(shè)計(jì)。其中進(jìn)行了必要的計(jì)算，同時(shí)繪制了相應(yīng)的零件圖和裝配圖。本套設(shè)備的主要特點(diǎn)是：打撈工作全部自動(dòng)進(jìn)行；結(jié)構(gòu)簡(jiǎn)單，操作方便；可以有效減輕勞動(dòng)強(qiáng)度，提高工作效率。

Abstract

Grid-mainly used for urban sewage, paper, petrochemicals, textiles, dyeingand printing, food processing, pharmaceuticals, and other waste water treatmentbefore therough Java-blocking treatment, sewage separation of suspended solids,floating on. Wastewater treatment through the grid-block, can protect the pump,but also the protection of follow-up treatment in the pipeline will not be blocked. Grid is the first sewage treatment processes, mainly to intercept sewage into the plant in the thick of the floating debris and to ensure follow-up treatment facilities to the normal operation of a pre-handling methods. Wastewater interception of the grille treatment, waste water to remove floating in the suspension of state or part of the pollutants, reduce the corruption level of wastewaterreatment and follow-up of the load. The design, the student access to a great deal of information for all kindsof machinery to do a full grid, and use the knowledge acquired by the designoa mechanical hook Rake automatic machine grid, including the work of agencies, drive system, the gate face, Shantiao bodies such as the design. Which carried out the necessary calculations, while drawing the corresponding parts and assembly plans. This set of equipment is the main characteristics: salvaging allthe work automatically; structure is simple, easy to operate; can effectively reduce labor intensity and enhance efficiency environmental protection of water
