I. overview

机械格栅是水处理过程中必不可少的清污拦渣处理设备，其变化和发展受到给排水专业人士的关注。它不仅能保证水处理后序工段和设备的正常运行，而且还直接影响出水水质。阶梯型格栅是我公司对国外技术消化后，结合国内污水处理工程的具体情况自行研究、开发、制造的一种新型格栅。

Mechanical grille is an essential cleaning and slag disposal equipment in water treatment process. Its change and development are paid close attention to by professionals of water supply and drainage. It can not only guarantee the normal operation of the water treatment section and equipment, but also affect the water quality of the effluent directly. The ladder type grille is a new type of grille designed and developed by our company after the digestion of foreign technology and the concrete situation of domestic sewage treatment works.

二、使用范围

Two, the scope of use

阶梯型格栅可广泛应用于城市污水及工业废水处理的漂浮物和悬浮物，也可用于泵站污物的消除，是水源处理的理想设备。

The ladder type grille can be widely used in urban sewage and industrial wastewater treatment of floating objects and suspended solids, and can also be used for pumping station sewage elimination, and is an ideal equipment for water treatment.

三、工作原理

Three, working principle

阶梯型格栅是从根本上改变了以往机械格栅依靠链传动或钢丝绳牵引粑齿，作回转和往复直线运动对格栅栅面所拦截的渣物进行消除的模式，而是利用爬阶梯一样的形式来提升渣物。

The ladder type grille is fundamentally changed in the past rely on mechanical grid chain drive or wire rope traction gear for rotary slag cake, and the interception of reciprocating motion of the grid surface elimination mode, but the use of the same ladder form to raise slag.

阶梯型格栅主要由机架、动静栅片组、驱动装置、传动机构及控制等部分组成。

The ladder type grille is mainly composed of a frame, a dynamic and static grid piece, a drive device, a transmission mechanism and a control part.

阶梯型格栅的工作原理是通过电气控制系统指令，控制置于格栅上部的驱动装置带动传动机构及动栅片组相对于静栅片组交替运动，利用动、静栅片组的阶梯型齿面将水中的漂浮物拦截，并缓慢逐级提升至格栅卸渣出口处，实现拦污、清渣的目的。

The working principle of ladder type grille is through the electrical control system in the upper part of the grid control instruction, the driving device drives the transmission mechanism and dynamic grid plate group relative to the static grid plate group alternating motion, using ladder type tooth surface static and dynamic grid plate group will float in water interception, and slowly raised step by step to grid slag discharge at the exit, to achieve the purpose of cleaning, trash.

四、主要特点

Four, the main features

阶梯格栅由于其独特的结构形式和工作方式，具有以下特点：

Because of its unique structure and working mode, the stepped grid has the following characteristics:

1、结构简单，无水下传动部件，易于维护管理；

1 、 simple structure, no water drive parts, easy maintenance and management;

2、运动无卡、堵，栅片具有自洁净能力；

2. No jam or jam in movement. The grid has self-cleaning ability;

3、水下运动部件均采用不锈钢材质制造，耐腐蚀性好，使用寿命长。

3 、 underwater moving parts are made of stainless steel, good corrosion resistance and long service life.

4、动、静栅片均为嵌插式，无需在断流的情况下进行栅片的更换、维护检修方便；

4, the moving and static grid are embedded type, no need to stop in the case of the replacement of the grid, maintenance, easy to repair;

5、分离效率高，格栅栅条间隙小，且能连续或间歇式运行，除渣效果好；

5 、 separation efficiency is high, the grid bar clearance is small, and can be continuous or intermittent operation, slag removal effect is good;

6、操作条件好，本装置可为封闭结构，运行噪音低，不影响周围环境；

6, the operating conditions are good, the device can be closed structure, running noise is low, does not affect the surrounding environment;

7、安装方便。阶梯格栅为一体化结构，安装时整机放入渠沟内，十分方便。

7, easy installation. Step grid integration structure, install the machine into the trench, very convenient.

五、润滑

Five, lubrication

阶梯格栅传动系统的关键部件和运动支承应定期进行加注润滑油或换润滑脂，并定期进行更换和清洗。

The key components and moving support of the transmission system shall be periodically filled with lubricating oil or grease, and replaced and cleaned regularly.
