ZNW系列圓網(wǎng)濃縮機(jī)

ZNW系列圓網(wǎng)濃縮機(jī)/ ZNW Series Cylinder Wire Thickener

用 途:

ZNW系列圓網(wǎng)濃縮機(jī)是用于造紙制漿流程中各種低濃段漿料濃縮洗滌的重力過濾設(shè)備。其進(jìn)漿濃度為0.5%-1%，出漿 濃度根據(jù)不同漿種為4-6%之間。

結(jié)構(gòu)特點(diǎn):

圓網(wǎng)濃縮機(jī)對(duì)漿料的濃縮主要是靠網(wǎng)籠內(nèi)外液位差進(jìn)行的，同時(shí)漿料也靠壓棍和網(wǎng)籠之間的擠壓力脫水實(shí)現(xiàn)濃縮的。

網(wǎng)籠是圓網(wǎng)濃縮機(jī)的主要部件，它由端輪幅，中間輪幅、濾網(wǎng)、主軸組成。目前濾網(wǎng)主要材料由鋼板鉆孔或高分子聚乙稀材料制造，使用時(shí)套上相應(yīng)目數(shù)的網(wǎng)布。

在圓網(wǎng)濃縮機(jī)上還裝有壓棍和刮刀，壓棍支承在網(wǎng)的側(cè)板上，由網(wǎng)籠帶動(dòng)。壓棍為包膠棍，輥面硬度為60-65°(肖 氏)。壓棍的壓力為手輪調(diào)節(jié)，壓輥配有刮刀，刀刃緊貼輥面，以剝落漿層。

圓網(wǎng)濃縮機(jī)在操作時(shí)應(yīng)注意兩點(diǎn)：一是要保持漿位的穩(wěn)定，防止溢漿和糊網(wǎng);二是要注意密封帶的緊固，阻止了漿料濃縮。

Application:

ZNW series Cylinder Wire Thickener can be used in the washing and dewatering of low con- sistency stock in paper making and pulping pro- cess. It works like a filter by gravity. The inlet consistency is around 0.5-1%, and outlet con- sistency is 4-6% based on different stock.

Design Features:

Its working principle is to dewater through the level difference between stock outside and inside of cylinder as well as press between press roll and cylinder.

As a main part of thickener, the cylinder con- sists of end spoke, middle spoke, filter wire and main shaft. The wire is made by steel plate with holes or UHMWPE plate covered with wires of different meshes.

It also have press roll and blade in the thicken- er. The press roll is driven by cylinder on the side plate, it is covered by rubber, the hardness of roll surface is 60-65 ° (Shore) . The pres- sure of press roll is adjusted by hand wheel. The press roll is equipped with blade, the blade is cling roll surface for peeling stock.

There are two points shall be pay attention when operation, one is to keep the stable stock level to avoid overflow and wire blocking, the other is that the tightened seal belt obstructs stock from thickening.
