工作原理，将铝生产废水先从进水口5排放到过滤箱1内进行第一次净化，废水内经过进水口5后落到过滤板6表面，由于过滤板6的四个侧面被挡板和拦截板7所围挡，落到过滤板6表面的废水只能通过过滤板6向下排放，从而提高废水的净化率，废水经过过滤板6后，废水中较大颗粒的废料和垃圾遗留在过滤板6表面，启动电机带动第一丝杆11进行旋转，第一丝杆11带动除尘板9在过滤板6表面进行移动，对过滤板6表面的废料进行清除，当除尘板9推动废料移动到拦截板7侧边时，顶块10优先接触拦截板7，通过除尘板9的移动，顶块10将拦截板7的底部逐渐推离过滤板6，使过滤板6产生缺口，方便除尘板9推动的废料从过滤板6表面去除，拦截板7被打开时，由除尘板9对废水做围挡，减少废水从缺口处的排放，从过滤板6表面脱离的的废料落倒导料板12表面，再从导料板12表面通过过滤箱1开设的下料槽排放到收集箱13内部，进行统一收集，当除尘板9将废料推出过滤板6后，第一丝杆11开始进行翻转，除尘板9逐渐远离拦截板7,顶块10也随除尘板9远离，当顶块10脱离拦截板7的侧边后，拉伸弹簧8拉动拦截板7的底部，重新闭合过滤板6。Working principle: Aluminum production wastewater is first discharged from the water inlet 5 into the filter box 1 for the first purification. After passing through the water inlet 5, the wastewater falls on the surface of the filter plate 6. Since the four sides of the filter plate 6 are surrounded by baffles and interception plates 7, the wastewater falling on the surface of the filter plate 6 can only be discharged downward through the filter plate 6, thereby improving the purification rate of the wastewater. After the wastewater passes through the filter plate 6, larger particles of waste and garbage in the wastewater are left on the surface of the filter plate 6. The start motor drives the first screw 11 to rotate, and the first screw 11 drives the dust removal plate 9 to move on the surface of the filter plate 6 to remove the waste on the surface of the filter plate 6. When the dust removal plate 9 pushes the waste to move to the side of the interception plate 7, the top block 10 contacts the interception plate 7 first, and through the movement of the dust removal plate 9, The top block 10 gradually pushes the bottom of the intercepting plate 7 away from the filter plate 6, so that a gap is generated in the filter plate 6, which facilitates the removal of the waste pushed by the dust removal plate 9 from the surface of the filter plate 6. When the intercepting plate 7 is opened, the dust removal plate 9 acts as a barrier for the waste water to reduce the discharge of waste water from the gap. The waste separated from the surface of the filter plate 6 falls on the surface of the guide plate 12, and then is discharged from the surface of the guide plate 12 through the discharge chute opened in the filter box 1 to the inside of the collection box 13 for unified collection. When the dust removal plate 9 pushes the waste out of the filter plate 6, the first screw rod 11 begins to flip, and the dust removal plate 9 gradually moves away from the intercepting plate 7, and the top block 10 also moves away from the dust removal plate 9. When the top block 10 is separated from the side of the intercepting plate 7, the tension spring 8 pulls the bottom of the intercepting plate 7 to close the filter plate 6 again.
废水经过过滤板6后，会与混药箱14进行碰撞，混药箱14内部的药剂随废水的冲击与废水进行混合，一同落入沉淀池2内，在沉淀池2内部进行进一步的净化沉淀，废水经过沉淀后，水底会堆积一层沉淀物，通过第二丝杆15带动刮板16，将沉淀池2底部的沉淀物推向出料口，使沉淀物排出沉淀池2内部。经过沉淀的废水得到进一步的净化后，从沉淀池2侧边的出水口通过水管落入净化箱3内部，在经过层层过滤净化后，流入收集池4内部进行统一收集，实现废水的净化再利用。After the wastewater passes through the filter plate 6, it will collide with the mixing box 14. The medicine inside the mixing box 14 will mix with the wastewater with the impact of the wastewater and fall into the sedimentation tank 2 together. Further purification and sedimentation will be carried out inside the sedimentation tank 2. After the wastewater is precipitated, a layer of sediment will accumulate at the bottom of the water. The scraper 16 is driven by the second screw 15 to push the sediment at the bottom of the sedimentation tank 2 to the discharge port, so that the sediment is discharged from the sedimentation tank 2. After the precipitated wastewater is further purified, it falls into the purification box 3 through the water pipe from the outlet on the side of the sedimentation tank 2. After being filtered and purified layer by layer, it flows into the collection tank 4 for unified collection, realizing the purification and reuse of the wastewater.
