转鼓式格栅除污机

一、产品简介
转鼓式格栅是我厂参考进口设备，自行设计。该设备将水源取水口漂浮物和沉积物打捞清除，并将栅渣挤干脱水后排出，适用于城市给水／排水，工业给水／排水等取水口用以截除水体中的污物。

二、工作原理:

转鼓式格栅除污机又称细栅过滤器或螺旋格栅机，是一种集细格栅除污机、栅渣螺旋提升机和栅渣螺旋压榨机于一体的设备。
格栅片按栅间隙制成鼓形栅筐，处理水从栅筐前流入，通过格栅过滤，流向水池出口，栅渣被截留在栅面上，当栅内外的水位差达到一定值时，安装在中心轴上的旋转齿耙回转清污，当清渣齿耙把污物扒集至栅筐顶点的位置时(时钟1 2点)，开始卸渣(能靠自重下坠的栅渣卸入栅渣槽)；而后又后转150，被栅筐顶端的清渣齿板把粘附在耙齿上的栅渣自动刮除，卸入栅渣槽。栅渣由槽底螺旋输送器提升，至上部压榨段压榨脱水后外运，栅渣固含量可达35％—45％。

Drum type grille decontamination machine Product introduction The rotary drum type grille is designed by our factory with reference to imported equipment. The device removes the water source float and sediment from the water source, and squeezes the slag to dry and drain. It is suitable for urban water supply/drainage, industrial water supply/drainage and other water intakes to remove dirt from water bodies. Working principle: The drum type grid decontamination machine, also known as the fine grid filter or the spiral grid machine, is a device integrating a fine grid decontamination machine, a grid slag spiral hoist and a grid slag screw press. The grid sheet is made into a drum grid according to the gap of the grid, and the treated water flows in from the front of the grid basket. The sewage is filtered through the grid and flows to the outlet of the pool, and the grid residue is trapped on the grid surface. When the water level difference inside and outside the grid reaches a certain value, the rotary tooth harrow installed on the center shaft turns to clean the dirt. When the slag tooth rake collects the dirt to the position of the top of the grid basket (clock 1 or 2 o 'clock), it begins to discharge the slag (can rely on the self-falling grid slag into the grid slag groove). After turning back 150°, the gate slag is automatically scraped off the grid slag adhering to the rake teeth by the slag cleaning plate at the top of the grid basket and discharged into the grid slag groove. The grid slag is lifted by the screw conveyor at the bottom of the tank, and is transported to the upper press section after dewatering, and the solid content of the grid slag can reach 35%-45%.
