It is designed of unique, compact, and with high filtration efficiency, high transparency, fineness of filtrate, no material loss, no consumption of filter paper, filter cloth or filter elements. So the filtration cost is very low and convenient to operate, maintain and clean.

The filter blade adopts special multi-layer stainless steel wire mesh with long service life, high output and high precision. The original pressure mechanism ensures low oil content, easy to operate and discharge slag. It is suitable for filtration separation process of grease decolorization, clarification and crystallization in oil, chemical and pharmaceutical industries.

【结构及工作原理】：

板式密闭过滤机是一款自动化压力式过滤装置，主要由壳体、过滤板、起盖结构、自动排渣装置等组成，其中过滤板是由多层不锈钢滤材组成，安装在中心集液管上，拆装清理十分方便。

助滤剂在混合缸中与物料混合后，通过输送泵打循环使得滤网片上形成稳定的滤饼层，即进行助滤剂预涂。预涂好后开始过滤，细小的助滤剂颗粒可提供无数的细微通道，困住悬浮的杂物，只容许清澈的液体通过，并在过滤过程中通过不断添加硅藻土等助滤剂以形成新的过滤层，使得滤饼不会有所堵塞，这样物料就通过滤饼层进行实质性的过滤，去其杂质，流入滤叶内腔，再经出液管，流出清液。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 and working principle:

Plate hermetic filter is an automatic pressure filter device, which is mainly consist of shell, filter plate, capping structure, automatic slag discharge device, etc. The filter plate is composed of multi-layer stainless steel filter material, which is installed on the central collecting tube. It is very convenient to disassemble, assemble and clean.

After the filter aid is mixed with the material in the mixing cylinder, a stable cake layer is formed on the filter mesh through the circulation of the conveying pump, that is, the filter aid is pre-coated. After pre-coating, filtration begins. The fine filter aid particles can provide numerous fine channels to trap the suspended impurities and only allow clear liquid to pass through. During the filtration process, the filter cake will not be blocked by adding filter aids such as diatomite, so that the material will be filtered substantially through the cake layer to remove impurities and flow into the filter leaf, cavity, the outlet tube and the clear liquid flows out. If decolorization is needed during filtration, a certain proportion of activated carbon should be added. If it is used for separating dirty liquids, such as crude oil, there is no need to add filter aids.

【主要特点】：

■ 机壳密闭、垂直滤叶、结构紧凑、运动部件少、易维修保养；
■ 根据过滤精度要求选择不同精度的过滤组件，可作为粗滤或者精滤。

■ 滤液回收完全，没有残液;

■ 过滤不用滤纸、滤布或纸芯，而是采用不锈钢过滤组件，经久耐用，而只消耗少量的助滤剂，因此过滤成本很低；

■ 自动排渣，按排渣按钮，排渣口即能自动打开，滤渣便能十分方便自动清除，从而劳动强度大幅度降低；

■ 根据客户要求可以增加硅藻土混合罐，增加隔膜式自动计量添加泵，整个过滤过程实现全自动化；

■ 过滤温度不受限制，操作人员少，方法简单；

■ 设备造形新颖、结构紧凑、占地面积小、操作简单可靠、维护和保养十分方便，且运行平稳，振动性小,生产效率高、消耗低；

■ 过滤后的液体透明和细度好，无物料损耗、清理方便，运行费用低廉 。

Main features:

● Sealed case, vertical filter blade, compact structure, few moving parts and easy to maintain.

● According to the requirements of filtering accuracy, different precision filter components can be selected as coarse or fine filters.

● The filtrate is completely recovered without residue.

● Rather than adopting filter paper, cloth or paper core, but stainless steel filter components, which are durable and consuming only a small amount of filter aids, thus, the low filtration cost is guaranteed.

● Discharge slag automatically. Press the slag discharge button, the slag discharge outlet can be opened automatically, and the filter slag can be removed automatically and conveniently, thus reducing the labor intensity greatly.

● Diatomite mixing tank and diaphragm automatic metering and adding pump can be added according to customer's requirements. The whole filtration process can be fully automated.

● The filtering temperature is not limited with fewer operators and simple method.

● The equipment is of novel appearance, compact structure, small volume, simple and reliable operation, convenient maintenance and service, stable operation, low vibration, high production efficiency and low consumption.

● The filtered liquid is of good transparency and fineness, and no material loss, easy to clean and low operating cost.
