Parameters
The diaphragm filter plate of o靜事ur company has won many national patent民從s and is widely used in soli坐動d-liquid separation in兵光 various industrial field分有s. Its main featu森學res are as follows:
(1) low pressure filt師話ration, effective數暗ly shorten the filtrati務術on cycle and improve produc廠線tivity.
(2) medium pressure filtr銀高ation, effectively草但 shorten the washing cycle, impr吃樂ove productivity.
(3) high pressure filtration can 照有more effectively reduce the moisture 我農content of filte鐘開r cake, reduce energy cons通吃umption or increase t件秒he yield.
(4) diaphragm replaceable diap師樹hragm filter plate, good sealing 習去performance, easy to di白司sassemble and replace鄉自, can greatly reduce the c什公ost of the product遠理ion process.
(5) special processing員資 technology, specific imported materi謝答als, long service life of fi笑些lter plate.
The diaphragm filter plat算商e is composed of two 習物diaphragm plates and 嗎近core plate, which is fed into the 但船external medium (wa懂自ter or compressed 雨木air, etc.) into the chamber betwee新員n the core plate and the diap師不hragm to make the diaphragm b術票ulge, so as to compress the f算得ilter chamber comp高歌osed of diaphragm filter plate and光話 chamber filter p有路late, so as to better separate and im都中prove the solid conten農朋t. The diaphragm is兒制 the main moving pa國器rt, and repeated movement is eas商是y to cause deformation a店車nd damage of the diaphrag火得m.
Diaphragm plate is 國看divided into rubb也去er diaphragm plat算章e and polypropylene diaphragm plate. Ru廠到bber diaphragm filter p照體late diaphragm is generally embedded 秒熱in the core of the groove, 日如easy to remove and replace, 拍農because the rubber diaphr頻森agm has a high degree of elasticity, 國姐so not easy to damage. Th件用e diaphragm of poly分美propylene filter plate is generally術子 welded in one piece. The場東 diaphragm formed by welding sha票黑ll not be replaced.
Advantages
1. Short filte錯土ring time
With the increase of間他 filtration time, t話畫he filter cake 謝路grows slower and slower. 裡跳In order to make the residual humi訊文dity in the filter residue low, th站行e filter plate frame and又農 the box filter plate need a東作 longer filtering time; The use o大區f JVK diaphragm 樹很filter plate can greatly reduce t一鐵he filtration time. The required 但一residual humidity is家舊 achieved by mechanica商光l extrusion of the ela土電stic diaphragm.
Residual humidity after filtration 長風of diaphragm filter plate:
A= diaphragm plate filtration en費體d point
B= end point of wing 城動filter
C= residual humidity aft做著er extrusion of diaph影綠ragm filter plate
A 'and C' are di畫會fferent possible out了業comes depending on the笑理 operation
Suitable operation point A can be愛文 determined aft風行er several filtration c從舞ycles.
2. Short washing time
The use of common filter e來錢lements can cause uneven c匠老ake formation, such as uneven washing 文輛due to wrinkling or 服亮cracking. The JVK di那西aphragm filter pla厭來te avoids this unevenness due to從說 the light press家新ure of the diaphragm during the washing問月 process. Because of the uniform c看訊apillary structure formed in the著文 filter cake, the washing effect i好白s very good, and the consumption讀慢 of washing liquid can be greatly reduc長土ed.
3. Low residual humidity
The high pressure filtration技雨 required in the filtration proces月舞s is replaced by a hig美老h elastic membrane extrus從我ion process on the filter 人民cake. The extrusio就山n process is not along the 喝他direction of the filter su喝我rface, but across the filt算章er surface. In a short time, the 懂志residual humidity in the filter cak地紅e decreased significantly, a技如nd the filtrate outflow increase動站d significantly. The benef河很its are as follows:算照
It saves energy costs
A special vacuum process 錯靜results in a solid content of almos鐵化t 100%
The blow-drying process is shortened
The filter cake sticks公行 less to the press cloth
The discharging time of fil藍志ter cake is obviously shorte錯很ned
The filtering process can be auto睡著mated
Lower pump costs
Because the filter報村 cake is compact and dry, the transpor玩車tation cost is reduced
Savings in storage costs
4. Diaphragm replaceabl林能e
The diaphragm can be 聽厭easily replaced 靜花inside or outsi吃呢de the filter press. If 市女the diaphragm is damaged on either s那物ide of the traditional diaphragm麗弟 plate, the entire diaphrag間是m plate should be replaced. Diaphrag西司m plate is a moving part of the p厭裡late, the maintenance cost們們s need to be consid舊科ered. The removable d資購iaphragm plate on either side can be妹可 replaced separately, and the co雪紙re plate continues to be u林答sed, greatly reducing maint媽美enance and replacement c她多osts.
5. The closing for新票ce of the filter短睡 press does not directly ac業裡t on the diaphragm
The diaphragm edge 湖對extends only to the seal of th你年e diaphragm plate core plate itself.制為 Therefore, the closing force of t民她he filter press does not 間如act on the diaphragm,可紙 but only on the 線機sealing surface of the filt間拍er plate core pl了化ate.
6. High elasticit離樂y of the diaphragm
Because of the good el些姐asticity of the membrane, the membrane照刀 can adjust itself without哥區 permanent deformat匠低ion for the une少器ven filter cake s的員urface formed during filtra鄉玩tion and the filter cake membrane知上 with different packing dens地好ity. This feature ensures even and 多一good cake extrusion.從技 JVK diaphragm filter plate pressure u術線p to 60bar, to meet a variety家吧 of industrial appl還到ications.
7. Even in the cavity state, the 小輛diaphragm movement will離音 not be out of order
The diaphragm is熱線 held in place where there is 業微no stress. The > diaph信要ragm can be squeezed into the 不聽cavity without failure, regardless of t和校he chamber depth.志習
The diaphragm filte友他r plate of JVK has no bolt什姐ed connection and is complet來睡ely sealed by the rubbe去文r diaphragm itself. Even if the 到很filter press is turned on when pres微湖sure is applied in the chamber of章水 the diaphragm chambe分制r by mistake, the 吃歌diaphragm on the JVK diaphra知坐gm plate will eject the fi跳事lter plate according to the pr制什essure to release the pressure, an不短d only need to be newly installed. The了件 traditional diap懂黑hragm plate is usually w文上elded or bolted, whic答吃h inevitably causes dama算厭ge.
8. There is no time l外說imit for diaphragm moveme電中nt
In some cases, the gradual increase議刀 and decrease of東視 pressure durin討的g feeding, washing and pressing ca南匠n be neglected. Thi廠她s process can be optimized with JV技森K diaphragm plates.
9. The filter p遠報late system has good能又 tightness
The filter plate core plate se如遠aling process is performed i用光n accordance with the German industry s快你tandard DIN 7129. T美道he diaphragm is secured on the perip就拿hery, so the chamber seals v見木ery well. The CGR design structur書兵e is a completely sealed str國能ucture of the JVK diaphragm filte熱我r plate.
10. Large filtrate outlet passa快還ge section
The diameter and number of fil呢計trate outflow channels from the filter路去 surface to the core of the filter pla黃她te are set according to the電上 requirements of the 頻老application. The diameter嗎兵 of the outlet channel 黑綠can be up to 10mm靜科, so the filtrate discharge can be黃秒 large, without soli女購d particles or crystals block購科ing the outlet channel.報子
11. Wide range of applications
The raw materials used上玩 at JVK ensure that t文快he product can be used i要費n almost all indust化煙ries and can be adapted to eac熱綠h specific working condition. With diap輛對hragm made of sp業動ecial elastomer and diaphragm plate c很我ore made of special material窗員, JVK diaphragm plate can be used 錯農for:
The temperature ranges from -20°C 自坐to +140°C
Filtration pressure up to 15bar
Press pressure去路 to at least 25bar
Extreme temperature change (sudd可吃en change in temperature章生)
Special chemical requirements
12. High safety 器街of diaphragm sy化數stem
There is no screw o事來r welded connectio視開n between the diaphragm a小會nd the sealing surface of the co拍著re plate. The pressure of the ext討小ruded media behind the diaphrag民村m can only be maintained by a closed fi黑會lter press. If the filter pr中商ess is open or just opened, but th現答ere is pressure in the diaphr計微agm, the diaphragm著木 will immediately move away from th說是e fixed groove, resulting 快為in a non-dangerous rel廠弟ease of pressure without damagi湖黑ng the diaphragm. The cost of sec電風urity maintenance ha白明s been significantly reduced.
