往復式矩形池底刮泥機是集污泥連續輸送與濃縮于一體的液壓往復式矩形池底刮泥機。矩形池底刮泥機由代鋼索拖拉刮板式、第二代桁車走橋吸泥式、第三代鏈條刮板式演變到現在的第四代液壓往復式，液壓往復式矩形池底刮泥機具有運動部件少、維護少、污泥連續輸送、可靠性高、安裝簡便、污泥濃縮等特性。往復式刮泥機已成功應用于大量不同型式的污泥沉淀系統，適用范圍廣。
齒輪油泵向液壓油缸提供動力，一組三角架將油缸的豎直運動轉換為水平運動、最后帶動-組楔形刮板在矩形池底作往復運動;往復運動的行程大于單根刮板的間距，相當于后-根刮板向前一根刮板傳遞污泥;刮板組前進的速度大約是后退速度的一半;前進時，楔形刮板的凹面在前、向池子的積泥溝推送積泥;后退時、很小的楔形銳角不會帶動污泥向后運動、而快速后退的凹面產生的負壓、會使-定厚度的污泥層保持向前運動的慣性。
因此當刮板作往復運動時、池底有一-層污泥始終在向前運動，直至跌入集泥溝。當池底積泥達到某- -厚度時、刮泥機的高。刮板的往復移動同時具有濃縮污泥的作用(可達3%)，這種特性在實際應用中突顯重要。當排污量相等時、污泥的濃度越高、其耗水率越低，這樣也就減少了水源與能源的損耗。
A gear oil pump provides driving force for a hydraulic oil cylinder. A set of triangular supports turns the vertical movements of the oil cylinder into horizontal movements and finally drives a set of wedge- -shaped scraping plates to reciprocate at the bottom of a rectangular tank. The travel of reciprocating movements is larger than the distance between scraping plates. In other words, the back scraping plate passes mud to the front scraping plate. The speed of advancing scraping plates is about half of that of backing scraping plates. When scrapping plates advance, the concave surface of the wedge- -shaped scraping plates is in the front and pushes mud towards a mud channel. When scrapping plates move backwards, the very small wedge - shape sharp corners won't carry sludge to move backwards and the negative pressure produced by rapid backward movements of the concave surface will keep the inertia of forward movements of sludge layers with a certain thickness.
Therefore, when scraping plates reciprocate, a layer of sludge at the tank bottom always moves forward until it falls into the mud trough.When mud at the tank bottom reaches a certain thickness, the efficiency of the mud scraper is highest. The reciprocation of scraping plates also has the function of sludge concentration (3%). This characteristic is very prominent in practical application. When the amount of mud discharge is the same, the higher the concentration of sludge is, the lower the water consumption rate is so the loss of water and energy is also reduced.
