A continuous supply of cooling water into the seal trough overflows into the SSC. 一個裝有水的不銹鋼制的水封槽安放在渣井結構上用以確保鍋爐和渣井之間的密封，連續(xù)供應的冷卻水注入水密槽并溢流進撈渣機（ SSC） A series of flushing nozzles are provided on the sides of the seal trough to aid in the removal of entrained ash particles. 一系列的沖洗水噴嘴安裝在水封槽的側面以助沖走渣塊。 Buyer : Guangdong Guohua Yeudian Taishan Electric Power Plant Project : Taishan Power Plant Phase I 3 x 600MW CBMH Project No. C6196 Contract No. 2020RCC/13069UK Document No. C6196/MM/1 Operating and Maintenance Instructions 7 Submerged Scraper Conveyor 刮板撈渣機 The top horizontal trough of the conveyor is water filled to a minimum depth of 2020mm. The water temperature is maintained at or below 60186。C during times of normal operation by means of a continuous cooling water supply from the station cooling water system. The overflow water passes through a lamellar filter then over a weir located on the inside of the trough. It is then discharged via two overflows down pipes to drain. 撈渣機槽的水面最小深度是 2020mm. 在正常工作狀態(tài)下 連續(xù)供應的冷卻水系統(tǒng)保持水溫為60186。C 或低于 60186。C。 溢流水通過一個薄的澄清板然后流過水槽里面的鋸齒板，通過兩個溢流水管道排走。 The casing is a minimum of 14 mm thick and is suitably stiffened. The bottom internal surface is lined with a 26mm thick abrasive resistant material having a minimum 400 BHN and the inclined surface is basalt lined with a chevron strip pattern in order to assist the dewatering of ash prior to discharge onto the belt conveyor. 箱體有最少 14mm的厚度，并被適度加強。 水平段內部是 26mm厚的耐磨鋼板，最小400BHN。斜升段設有帶 v形槽的鑄石板以利于撈渣機渣的脫水。 The return trough is lined with basalt tiles and is open (but suitably guarded) in order to facilitate ease of access at times of maintenance. 鋪有鑄石板的返回槽是開口的（用于適當監(jiān)查）以保證維修時方便 Removable side plates are incorporated into one side of the top horizontal trough to enable the conveyor to be retracted from the operating position at times of plant maintenance. 水平槽的上部側面有可移動的側板可保證鍋爐維修時把撈渣機拖出來。 The conveyor and associated chains are suitably sized to acmodate all modes of specified operation and are designed to be able to extract ash when the SSC trough is full. 撈渣機和相配的鏈條選型恰當可適應各種工礦條件， SSC 槽滿時可以把渣撈出來。 An automatic hydraulic chaintensioning unit is incorporated into the tail section of the conveyor plete with alarm indication. 在撈渣機尾部配有報警顯示的自動液壓鏈輪張緊裝置。 The conveying chain is of the round link design and has a surface hardness of 800 HV minimum. The wear edges of the conveying flight bars are of abrasive resistant material and are designed to have a minimum of 16000 operating hours. Bearing service life is in the order of 40000 operating hours and the submerged bearings are suitable for operation between a temperature range of 20186。C to +85186。C, all bearings are grease lubricated. 鏈條是圓環(huán)設計，最低表面硬度 800HV。傳送刮板的接觸面由耐磨材料制成，工作壽命為最低 16000工作小時。軸承的工作壽命是 40000工作小時。浸水軸承可以在 20186。C到 +85186。C的溫度范圍內工作， 所有軸承由潤滑脂潤滑。 A hydraulic power pack is installed at the base of the conveyor incline and is suitably designed to drive the conveyor at all times under all modes of operation. The maximum forward speed of the chain is m/min and SSC trough pletely full of ash. 液壓動力站安裝在斜升段的底部，合理設計以保證在各種工礦下工作。鏈條的向前速度是 米 /分鐘和反轉速度是 /分鐘 。在撈渣機槽充滿底渣停止工作后驅動裝置能夠啟動運行。 All necessary pipework and associated supports for cooling, makeup and chain cleaning supplies are provided. Exact location of the chain cleaning sprays ensures that only the chain Buyer : Guangdong Guohua Yeudian Taishan Electric Power Plant Project : Taishan Power Plant Phase I 3 x 600MW CBMH Project No. C6196 Contract No. 2020RCC/13069UK Document No. C6196/MM/1 Operating and Maintenance Instructions 8 is cleaned, this ensures that there is minimum water effect to the conveying ash and the downstream equipment. 隨附的還有管路和與冷卻，補充水，鏈條清洗相關的支撐。鏈條清洗噴嘴的準確定位能保證鏈條的清洗，益于渣的傳輸和對下游設備影響最小。 Crusher amp。 Ash Conveyor (Unit 3 only) 碎渣機 amp。二級刮板（僅 3機組） The submerged scraper conveyor deposits ash via a feed chute and a twin roll crusher direct onto a smaller ash scraper conveyor. 底渣由刮板撈渣機的斜槽和一個雙輥的碎渣機直接落到一個小的二極刮板上。 The crusher is designed to acmodate the maximum tonnage rates of the SSC. The crusher drive is hydraulic and oil is supplied from the same hydraulic powerpack as the SSC. The crusher is mounted on rails for easy removal to the maintenance position. 碎渣機的設計來適應撈渣機的最大排渣量。碎渣機的液壓驅動和液壓油都是來自撈渣機的液壓動力站。安裝在軌道上的碎渣機易于移動到檢修位置。 After crushing the ash is deposited onto the ash conveyor and transported along the basalt lined conveyor bottom deck. 然后磨碎的渣落入二級刮板中并沿著二級刮板鋪有鑄石板的底板傳輸。 The conveying chain is of the round link design and the wear edges of the flight bars are of abrasive resistant material and are designed to have a minimum of 16000 operating hours. 鏈條屬于圓環(huán)設計，刮板耐磨板屬于耐磨材料， 工作壽命最少是 16000工作小時 The ash is conveyed up the conveyor incline and deposited via a discharge chute into the ash silo. For maintenance purposes a stairway is provided along the length of the conveyor for access to the silo top and the conveyor inspection doors. 底渣被運輸?shù)叫鄙稳缓笸ㄟ^卸料槽進入渣倉。為便于檢修，沿二級刮板到渣倉和二級刮板的觀察門設有通道平臺。 A variable speed electric drive and gearbox is mounted at the head of the conveyor on top of the silo. The speed is controlled via a frequency inverter mounted in the ash conveyor local panel. 在渣倉頂部二級 刮板的頭部裝有一個可調速的電驅動裝置。速度通過二級刮板上的就地控制盤中的變頻器調節(jié)。 A screw take up arrangement at the tail end effects the chain tensioning.
