Basic Specification:

Candle filter is also known as cake layer filter and a single internal integrate multiple tubular filter elements. After filtering to a certain pressure difference and the liquid being emptied, filter elements can be reused by removing the cake using reverse blowing. Candle filter has the outstanding characteristics of airtight operation, multi-function, large filtering area, strong contamination capacity, easy back-blown filter cake and automatic operation. Meanwhile, it has five functions: direct filtration, pre-coating filtration, slurry concentration, cake recovery and cake washing. It can be applied to high impurity content, viscous liquid, extremely high precision, high temperature and other special filtering occasions. For example, filter aids of diatomite, cellulose and perlite can be used as pre-coated. A parallel system consists of two filters with the procedure of continuous filtering, PLC control, automatic implementation of pre-coating, filtering, slag discharge, cleaning and so on. Multiple candle filters can be integrated into a large-scale filtering system.

    烛式过滤机是一款自动化压力式过滤装置，主要由筒体、滤芯、滤布、助滤剂、电脑控制系统和配件等组成，其他辅助设备包含空压机，压力感应器等，筒体和滤芯的材质主要为不锈钢（304/316/321）、碳钢、钛材，滤布的材质主要为PP(聚丙烯）、PE（聚酯）、PPS(聚苯硫醚)、PTFE(聚四氟乙烯)、尼龙纤维等，助滤剂则按生产过程中的过滤标准要求来配置，主要有活性炭、硅藻土等。

    滤布支撑管由一支无孔中心管与六根多孔管组成，截面为梅花型，中心管能够排尽滤元内驻存液体，减少物料浪费。

    过滤状态：液体透过滤布，从外部多孔管中流向中心管，再流向集液管。滤布受压贴附于支撑管外表面，凹凸的支撑管能够增大过滤面积并帮助固定滤饼，防止滤饼脱落，从而稳定过滤效果。

    反吹状态：通入反吹气体，从无孔中心管流向外部多孔管，滤布鼓胀变圆，有效振飞剥离滤饼，同时可以振去滤布纤维中的微粒，提高反吹效率，快速恢复滤布过滤能力。

Structure and working principle:

Candle filter, an automatic pressure filter device, is mainly composed of cylinder, filter element, filter cloth, filter aids, computer control system and accessories. Other auxiliary equipment includes air compressor, pressure sensor, etc. The material of cylinder and filter core is mainly stainless steel (304/316/321), carbon steel and titanium. The material of filter cloth is mainly PP (polypropylene), PE (polyester), PPS (polyester), PTFE (polytetrafluoroethylene), nylon fibers, etc. Filter aids are allocated according to the filter standard requirements in the production process, mainly including activated carbon, diatomite and so on.

The filter cloth support pipe is composed of a non-porous central pipe and six porous pipes. The cross-section is plum blossom type. The central pipe can drain the liquid stored in the filter element and reduce material waste.

Filtering state: liquid passes through the filter cloth, flows from the external porous tube to the central tube, and then to the collecting tube. The filter cloth is pressed and attached to the outside surface of the supporting pipe. The concave and convex supporting pipe can increase the filtering area and help fix the filter cake, which prevents the cake from falling off, thus stabilizing the filtering effect.

Reverse blow state: starting reverse blowing gas, it flows from the non-hole central pipe to the external porous pipe and the filter cloth swells and turns round, so the filter cake can be effectively peeled by vibration and flying, and meanwhile, the particles in the filter cloth can be vibrated to improve the reverse blow efficiency and quickly recover the filtering capacity of the filter cloth.

【主要特点】：

■ 用于液体的澄清时，可在料浆中直接加硅藻土、活性炭等助剂，使过滤速率更快，滤液更澄清。
■ 全密闭操作，既适合于一般物料的过滤，也可用于易燃易爆、有毒或剧毒的危险产品及不允许有污染的鲜美食品、生物制品及药品等的过滤。

■ 在过滤后期，如底部残留料浆不能排回料浆槽，这时可用泵抽出底部的残留料浆，再返回顶部中央的过滤机顶盖内，并通过喷嘴均匀喷洒到过滤管上，通过机内输入压缩气体使残留的液体全部滤出。

■ 由于本机可再过滤时形成均匀的滤饼层，因而可在机内通入洗涤液很方便地对滤饼进行洗涤。如通过顶部喷淋的方法对滤饼进行洗涤，则可大大节省洗涤液。

■ 如要得到干燥滤饼，则在过滤后或洗涤过滤后在机内通入常温空气、热空气或蒸汽等，使他们穿过滤饼层，直至使滤饼达到所需的干度后再使机内泄压，并反吹滤饼从底部卸料。

Main features:

● When used for liquid clarification, diatomite and activated carbon can be added directly to the slurry to make the filtration rate faster and the filtrate clearer.

● Fully closed operation, which is suitable for the filtration of general materials, also for flammable, explosive, toxic or highly toxic dangerous products as well as delicious food without pollution, biological products and pharmaceuticals.

● In the later stage of filtration, when the residual slurry at the bottom cannot be discharged back to the slurry trough, the residual slurry at the bottom can be pumped out and returned to the top cover of the filter in the middle of the top. The residual liquid can be filtered out by spraying uniformly on the filter tube through the nozzle and injecting compressed gas into the filter.

● Because this machine can form a uniform cake layer when it is re-filtered, it is very convenient to wash the cake by introducing washing liquid into the machine. If the filter cake is washed by top spraying method, the washing liquid can be greatly saved.

● If dry filter cake is to be obtained, normal temperature air, hot air or steam will be introduced into the machine after filtering or washing and filtering, so that they can pass through the filter cake layer until the filter cake reaches the required dryness, then the pressure will be released in the machine, and the filter cake will be discharged by reverse blowing from the bottom.
