产品概述

DZBL高效密闭板式过滤机属于叶片过滤机，是我司在借鉴国外技术的基础上设计开发的新一代过滤设备，是一种高效、节能、密闭操作的精密清过滤设备。该产品设计结构独特，体积小，过滤波动，过滤效率高、滤液透明度和澄清度好，无物料消耗。不消耗滤纸，滤布或滤芯，只消耗少量的助滤剂，因而过滤成本很低，设备操作、维护、清理方便。该设备可以定制为手动排渣和自动排渣两种，过滤面积从2 平方到200平方，根据过滤的工艺要求，密闭容器有碳钢与不锈钢两种材质供用户选择。

Product Instruction

DZBL high efficiency inclosed leaf filter belongs tostainless steel woven mesh filter. It is the new generation filtration equipment that we developed refferencing foreign technology. The filter has unique and compacted design, and high filtering efficiency. It does not consume the filter cloth, filter paperor filter cartridge, just uses a little filter aid, so thee filtration cost is low. And the machine is easy to operate， maintain and clean. Manual discharging and auto discharging are available according to custorner's，requirement. The filter area ranges from 2 m² to 200 m². The housing material can be carbon steel or stainless steel to meet clients' different needs.

主要结构及工作原理

DZBL型高效密闭板式过滤机主体是由壳体、滤网片、起盖机构、自动排渣装置等组成，还可以根据过滤介质的不同定制完整的过滤系统（含过滤器主机和混合缸、输送泵、输送泵、管道、阀门、电气控制等），其中滤网片是由多层不锈钢网组成，安装在中心集料管上，装拆清理十分方便。

助渗剂在混合缸中与物料混合后，通过输送泵打循环使得滚网片上形成得定的滤饼层，即进行助诱剂预涂。预涂好后开始过滚，细小的助滤剂颗粒可提供无数的细微通道，图住悬浮的杂物，只容许清意的流体通过，并在过渡过程中通过不断添加硅藻土等助诱剂以形成新的过滤层，使得滤饼不会有所堵塞，这样物料就通过滤浮显进行实质性的过滤，去其杂质，流入滚叶内腔，再经出液管，流量，流管，流出清液，流液，如果过滤时需要脱色，还需加入一定比例的活性碳。若用于机榨毛油等比较脏的液体固液分离作业，则无需添加助滤剂。

Structure & Principle

The leaf filter consists of filter housing, filter screen, head lifting device and discharging device. According to the different filter materials it can customize various whole filtration system (Include the filter, mixing tank, feeding pump, pipes, valves, ccontrol system, etc.). The leaf is made of layers of sstainless steel wire screens, then installed on the central filtrate collecting tube, so it's convenient to discharge and clean.

The material mixed with filter aids in the mixingtank first, then pumped it into the filter circularlyto form a layer of filter cake. This process called the diatomite precoating and then begin to filter. The tiny filter aid particles can provide countless wispychannels to block the suspended solids, and onlythe clean liquid can go through. And while filtering,the new layers will be formed, and it will not cause block, thus realize filtering via filter cake layer. When filtering, if need decoloration, activated carboln might be needed. If filter the dirty liquid, such assqueezed crude oil, no need adding the filter aid.
