Operation guide book

Preface

Correct operation, serious maintenance and observing safety regulation are of necessity for raising operation efficiency, prolonging service life and ensuring safety. To avoid accident and raise production efficiency, the operator should know the operation of filter press well and be familiar with its’ structure and filtration principle.

Now we manufacture box filter, plate-frame filter and diaphragm filter press and box filter press is our main product. So this Manual is based on box type. The working principle of plate-frame one is similar with box type, so the Manual is also used for plate-frame one as a reference.

前言

正确安装使用压滤机，认真维护、保养和严格遵守安全操作规程是提高设备使用效率、延长设备使用寿命、保证安全生产的必要条件。因此操作者应熟练掌握压滤机的正确操作方法，还应熟悉压滤机的基本结构和过滤基本原理，才能提高生产效率及避免不必要的设备事故或损坏。

目前我公司生产的压滤机主要有厢式、板框式和隔膜压榨式等系列，厢式压滤机与板框式压滤机相比有许多优越性。在实际生产中以厢式压滤机为主。本说明书也是根据厢式压滤机操作特点而编写的，但板框式压滤机与厢式压滤机工作原理基本相似，所以也能参考。

Briefing

The principle of filter press is that the pressure difference on two side of filter cloth push the liquid in material penetrating the cloth and exiting the filter press and the material remains in filter as filter cake. Filter press is widely used in chemical, pharmacy, ceramic, sugar, dye, cement, silicate and other industry.

                         概述

压滤机是利用滤布两边的压力差，迫使物料中的绝大部分水份透过滤布，流出机体外，而物料被阻隔在滤室内形成滤饼，以达到过滤的目的。目前，压滤机已广泛用于化工、制药、冶金、陶瓷、制糖、颜料、染料、水泥、硅酸盐等工业以及市政与工业污泥脱水等方面。

                    Installation

1. Filter press shall be installed on cement foundation horizontally and secondary grouting is necessary.(The pedestal of thrust plate shall be fixed with bolts and the pedestal of oil cylinder shall not be fixed).

To convenient discharging, one meter free space around filter should be arranged. Filter shall avoid rain and direct sunshine.

2. Connecting power. The motor shall rotate clockwise.

3. Open air cleaner and add hydraulic oil to a level lower than motor

4. Mount return pipe, stop valve and pressure gauge.

5. Mount filter cloth.

6. Final check.

安装

1.压滤机应水平安装于混凝土基础结构上，安装的基础应采用二次灌浆。（注意在止推板下方的支架处用螺栓固定，油缸下方支架不需固定，不要包水泥）以保证压滤机在受压情况下的自由度。考虑到压滤机在卸料时便于操作，机架周围应留一米左右的空间。

2.接好电源，电机需顺时针旋转。

3. 打开空气滤清器注入液压油，油面高度与电机盖板水平稍低一些。

4. 进料管处应安装回流管、截止阀和压力表。

5. 装上滤布。

6．zui后的检查工作。

Piping installation and operation sequence

1. See sketch for piping installation.

2.  operation sequence

(1) press plate and frame

(2) open charging valve, shut return valve

(3) start charging pump

(4) control the filtration pressure by adjusting return valve to required pressure , but no higher than 0.4Mpa

 (5) adjust charging pressure by control return valve. When filter liquid’s flow rate becomes rather low, shut down charging pump and release the filter plate to unload filter cake.

 (6) If the filter cake is not dry enough, press the filter plate and filtrate again.

工艺管线安装和操作程序

1.工艺管线安装示意图

2．操作程序

（1）压紧板框；

（2）打开进料阀，关闭回流阀；

（3）启动进料泵；

（4）观察压力表在过滤过程中的压力，根据实际情况控制过滤压力，打开回流阀，使压力控制在0.4Mpa以下;

（5）用回流阀调节进料压力,直至过滤的出液量很小,即可关闭进料泵,若不需要洗涤,既可打开滤板,卸料;

（6）如打开滤板,感到滤饼不够干,可继续合上压紧板，再度过滤；

Precaution

1. Filter press shall be operated with the required filter plates installed by specified sequence .

2. The pressure of oil cylinder shall not exceed rated value.

3. The Valves shall be opened in a sequence specified in Operation Manual.

4. The temperature of filter material shall not higher than 80℃.

5. when moving filter plate, care must be taken to avoid collision and protect the sealing surface and handles.

6. After unloading filter cake, filter plate and filter cloth shall be cleaned and no residual shall be left on the sealing surface and passage.

7. Right filter cloth shall be used to meet filtration requirement.

8. Filter cloth shall be checked periodically.

9. The hydraulic elements of oil box, oil cylinder, oil pump and return valve shall be no-load operated periodically and cleaned .

10.Normally the oil shall be changed after first operation and then every six month. The oil shall be filtrated to 20um.

11. For lifting filter press, see sketch  .

注意事项

1．必须按次序和规定的数量放置滤板。

2.油缸的压力不得超过额定值。

3.阀门必须按操作程序启用。

4.过滤的滤浆温度必须控制在不高于80℃。

5.移动滤板时，用力应均匀适当，不得碰撞摔打，以免损坏密封面及手柄。

6.卸饼后的滤板和滤布必须冲洗干净，绝不允许有残渣贴在密封面或孔道上。

7.滤布选择一定要符合滤浆的过滤要求。

8.滤布在需定期检查。

9.油箱、油缸、油泵和溢流阀等液压元件需定期进行空载运行，循环清洗干净。    

10.在一般工作环境下*次使用的压滤机应在一个月内换油。工作油的过滤精度为20um，工作油的更换周期为6个月。
