二、产品特点Product features：

 系列带式压滤机的构造紧凑、式样新颖、操作管理方便，处理能力大、滤饼含水率低，效果好。它与同类型设备相比，具有以下特点：

 The series belt filter press has the advantages of compact structure, novel pattern, convenient operation and management, large processing ability, low water content of filter cake and good effect. Compared with the same type of equipment, it has the following characteristics:

 1、..重力脱水段为倾斜式，使污泥距地面高达1700mm，使污泥在重力脱水段高度增加，提高了重力脱水能力。

 The first gravity dehydration section is tilted, which makes the sludge from the ground up to 1700mm, which increases the height of the sludge in the gravity dehydration section and improves the dehydration capacity of the gravity.

 2、重力脱水段长，..与第二重力脱水段总长5m多，使污泥在压榨前充分脱水失去流动性。同时，重力脱水段还设置反转等特殊机构，经“楔”形、“S”形压榨等作用使污泥滤饼获得.低含水量。

 The gravity dehydration section is long, the first and second gravity dehydration sections are more than 5m, so that the sludge is dehydrated before the press is fully dehydrated. At the same time, special mechanisms such as reversal are also set in the gravity dehydration section, and the minimum water content of the sludge filter cake is obtained by the effect of "wedge" shape and "S" form pressing.

3、..个脱水辊采用“T”型泄水槽，使压榨后的大量水迅速排出，从而提高了脱水效果。

 The first dehydrating roll adopts the "T" type discharge tank, which makes a large amount of water discharged rapidly after the press, thus improving the effect of dehydration.

4、滤带跑偏等设有自动控制装置，滤带张力和滤带移动速度可自由调整，操作管理方便。

 There is an automatic control device for the running of the filter belt and so on. The tension of the filter belt and the moving speed of the filter belt can be adjusted freely, and the operation and management are convenient.

5、噪音低、无振动。

Low noise and no vibration.

6、化学药物用量少。

The dosage of chemical drugs is less.

三、工作原理The working principle：

 经过浓缩的污泥与一定浓度的絮凝剂在静、动态混合器中充分混合以后，污泥中的微小固体颗粒聚凝成体积较大的絮状团块，同时分离出自由水，絮凝后的污泥被输送到浓缩重力脱水的滤带上，在重力的作用下自由水被分离，形成不流动状态的污泥，然后夹持在上下两条网带之间，经过楔形预压区、低压区和高压区由小到大的挤压力、剪切力作用下，逐步挤压污泥，以达到.大程度的泥、水分离，.后形成滤饼排出。

 After the sludge concentration and flocculant concentration in static and dynamic mixer mixing, tiny solid particles in the sludge into larger poly flocculent masses, and separation of free water, flocculated sludge is transported to the concentrated gravity dewatering filter belt, are separated in the free water under the action of gravity the formation of the flow state of the sludge, and then sandwiched between the upper and lower two belts with wedge after preloading, the low pressure zone and the high pressure area from the extrusion pressure, shear stress, gradually squeezing sludge, mud and water in order to achieve the maximum degree of separation, and finally form a cake discharge.

1、化学预处理脱水Chemical pretreatment dehydration

 为了提高污泥的脱水性,改良滤饼的性质,增加物料的渗透性,需对污泥进行化学处理,本机使用独特的“水中絮凝造粒混合器”的装置以达到化学加药絮凝的作用，该方法不但絮凝效果好，还可节省大量药剂，运行费用低，经济效益十分明显。

 In order to improve the dewatering performance of sludge, improved the properties of filter cake, increase the permeability of the material, the need for sludge chemical treatment, the machine uses a unique "water flocculation mixer" device to achieve chemical flocculation effect, this method not only has good flocculation effect, can save a lot of drugs, low operation cost. The economic benefit is very obvious.

2、重力浓缩脱水段Gravitational dehydration section

 污泥经布料斗均匀送入网带，污泥随滤带向前运行，游离态水在自重作用下通过滤带流入接水槽，重力脱水也可以说是高度浓缩段，主要作用是脱去污泥中的自由水，使污泥的流动性减小，为进一步挤压做准备。

 The sludge hopper evenly into the net with the sludge with the filter belt to move, free water under gravity through the filter belt into the gutter, gravity dehydration can also be said to be highly concentrated, the main role is to remove the free water in the sludge, the sludge flow decreases, preparing for further extrusion

 3、楔形区预压脱水段Prepressure dehydration section in wedge-shaped region

 重力脱水后的污泥流动性几乎完全丧失，随着带式压滤机滤带的向前运行，上下滤带间距逐渐减少，物料开始受到轻微压力，并随着滤带运行，压力逐渐增大，楔形区的作用是延长重力脱水时间，增加絮团的挤压稳定性，为进入压力区做准备。

 The flow of the sludge gravity dehydration after almost completely lost, with the belt press filter belt is moving forward on the filter belt spacing gradually reduced, the material began to be slight pressure, and with the filter belt running, pressure gradually increases, the wedge area is the role of extended gravity dehydration time, extrusion stability increased floc, do prepared to enter the pressure zone.

 4、挤压辊高压脱水段The high pressure dehydration section of the extrusion roll

 物料脱离楔形区就进入压力区，物料在此区内受挤压，沿滤带运行方向压力随挤压辊直径的减少而增加，物料受到挤压体积收缩，物料内的间隙游离水被挤出，此时，基本形成滤饼，继续向前至压力尾部的高压区经过高压后滤饼的含水量可降至.低。

 The material from the wedge into the pressure zone, the material in this area by squeezing, running along the direction of the filter belt pressure increases with the decrease of extrusion roller diameter, material by extrusion shrinkage, clearance of free water in material is extruded, the basic form filter cake, high pressure area continued to pressure the pressure after the tail the water content of the filter cake can be reduced to the lowest.

5、物料排出Discharge of material

 物料经过以上各阶段的脱水处理后形成滤饼排出，通过刮泥板刮下，上下滤带分开，经过高压冲洗水清除滤网孔间的微量物料，继续进入下一步脱水循环。

 After dewatering, the material is filtered out, scraped down through the scraper plate, separated from the upper and lower filter strips. After the high-pressure rinse water is removed, the trace materials between the holes of the filter mesh are removed, and proceed to the next dehydration cycle.
