鏈條式刮泥機

鏈條式刮泥機其主要由驅動機構、主梁、中心旋轉支座、導流筒、刮泥系統、排渣斗及沖洗機構、鉸接式刮渣耙、撇渣板、撇渣斗、出水三角沿板、浮渣擋板、控制箱等部件組成，浮渣刮板將液面的浮渣由池中心撇向池周，收集在鉸鏈式刮渣耙區內，收集的浮渣隨主機在池周運動至撇渣斗，通過刮渣耙的鉸鏈活動刮至撇渣斗內，排至池外。

鏈條式刮泥機是一種懸掛式除泥設備，適用于水處理工程中圓形的初沉池、二沉池、濃縮池排除污泥。沉淀池為混凝土或鋼結構，池底稍呈圓錐形，池底中央為排泥斗外接排泥管。工作橋為混凝土或鋼結構，本設備不包括池體和工作橋，用戶自行解決，我廠可設計制造鋼結構池體和工作橋，供應用戶,刮泥機由耙架、豎軸驅動裝置和過扭距安全裝置等組成。

耙齒底邊距池底保持50mm允差±100mm。豎軸下端,在排泥斗上方，裝滑動軸承，尼龍襯套，采用壓國清水潤滑。必須設置Dg15潤滑水管，由池外引至池底，埋設在池底，水管外面表面不可以高于池底表面，在排泥斗外側伸出 ，與滑動軸承的管接頭接通。引入常壓力清水，保證潤滑良好，才可以試車運行。正常運行時，也必須在開車前，接通壓力清水，保持水下軸承潤滑良好。豎軸上端向心軸承和止推軸承組件，采用潤滑脂潤滑，要求潤滑良好。試車時，整機空負荷運行不少于2小時，要求運行平穩 ，噪音在80dB以下。帶負荷試運行不少于24小時。

傳動刮吸泥機適用于大中型幅流式二次沉淀池的機械排泥。依據池徑大小不同又分為單周邊傳動和雙周邊傳動,功效基本同于傳動刮泥機，主要用于大型(一般指池徑大于20m)污水廠的初沉及二沉池中，刮集池底沉泥(比重一般小于1.2且不易板結),一般上部設浮渣(或浮沫)刮集系統,即具有刮沉刮浮功能,工藝一般為中心進水,周邊出水,中心排泥。

The chain scraper is mainly composed of driving mechanism, main beam, central rotating support, guide cylinder, scraper system, slag hopper and flushing mechanism, articulated scraper, skimming board, skimming bucket, outlet triangle plate, scum baffle, control box and other components. The scum scraper skims the liquid surface from the center of the pool to the periphery of the pool and collects the scum in the hinge scraper area The main engine moves to the skimming bucket around the pool, scrapes to the skimming bucket through the hinge of the scraping rake, and discharges to the outside of the pool.

The chain scraper is a kind of suspended desilting equipment, which is suitable for the removal of sludge from the round primary sedimentation tank, secondary sedimentation tank and concentration tank in the water treatment project. The sedimentation tank is of concrete or steel structure, the bottom of the tank is slightly cone-shaped, and the center of the tank bottom is the sludge discharge bucket connected with the sludge discharge pipe. The working bridge is of concrete or steel structure. This equipment does not include the pool body and working bridge. The user can solve it by himself. Our factory can design and manufacture the steel structure pool body and working bridge for the user. The scraper is composed of rake frame, vertical shaft drive device and over torque safety device.

The tolerance between the bottom edge of the rake teeth and the pool bottom shall be 50mm ± 100mm. At the lower end of the vertical shaft, install the sliding bearing and nylon bushing above the sludge discharge bucket, and lubricate it with compressed water. The dg15 lubricating water pipe must be set, which is led to the bottom of the pool from the outside of the pool and buried at the bottom of the pool. The external surface of the water pipe cannot be higher than the surface of the pool bottom. It extends outside the mud hopper and connects with the pipe joint of the sliding bearing. Only when constant pressure water is introduced to ensure good lubrication, can the test run be carried out. During normal operation, it is also necessary to switch on the pressure clean water before start-up to keep the underwater bearing well lubricated. The centripetal bearing and thrust bearing components at the upper end of the vertical shaft are lubricated with grease, which is required to be well lubricated. During the test run, the whole machine shall run at no load for no less than 2 hours, and the operation shall be stable with noise below 80dB. The on load test run shall not be less than 24 hours.

The drive scraper is suitable for the mechanical discharge of large and medium-sized secondary sedimentation tanks. It can be divided into single peripheral drive and double peripheral drive according to the size of the pool diameter. Its function is basically the same as that of the drive scraper. It is mainly used in the primary and secondary settling tanks of large-scale (generally larger than 20 m) sewage plants. The bottom of the scraper (the proportion is generally less than 1.2 and not easy to harden). Generally, the upper part of the scraper is equipped with a scum (or foam) scraping system, which has the function of scraping, settling, scraping and floating. The process is generally the central water inflow, The surrounding water is discharged and the center is discharged with mud.
