Parameters
The diaphragm f中看ilter plate of our company has won man用內y national patents and is widely u學白sed in solid-liquid separa事年tion in various in光日dustrial fields. Its main和答 features are as follows:
(1) low pressure filtration, effective哥麗ly shorten the filtra機朋tion cycle and improve productivity.高為
(2) medium pressure filtration, e民知ffectively shorte她老n the washing cycle, im呢厭prove productivity.
(3) high pressure filtration can mor一木e effectively reduce the moisture conte鄉站nt of filter cak船要e, reduce energy con議還sumption or incr了習ease the yield.
(4) diaphragm repla見看ceable diaphragm filter plate, good sea大長ling performance, easy to disass讀熱emble and repla農飛ce, can greatly 微國reduce the cost of the productio匠在n process.
(5) special processin腦什g technology, specific imported ma電用terials, long service life of fi靜還lter plate.
The diaphragm fi議作lter plate is compose腦我d of two diaphragm plates and core plat報站e, which is fed into the external m要高edium (water or可影 compressed air, 廠師etc.) into the 人明chamber between the core plat森這e and the diaphragm to make the d跳對iaphragm bulge, so高師 as to compress 遠頻the filter chamber composed身機 of diaphragm fi子土lter plate and chamber fil技又ter plate, so as to better se文一parate and improve the solid con術行tent. The diaphragm is the main m資和oving part, and repea花麗ted movement is秒很 easy to cause deformation and damage 南些of the diaphragm.
Diaphragm plate is話國 divided into ru市美bber diaphragm plate錢中 and polypropylene diaphragm plate. Ru遠理bber diaphragm filter plate diaph日白ragm is generally 從章embedded in the core of the groove, ea件什sy to remove and replace, because 劇公the rubber diaphragm has弟呢 a high degree of elasticity, so not草又 easy to damage. The diaphra月這gm of polypropylene filter plate is錯的 generally welded in one pi在水ece. The diaphragm formed by weldin城睡g shall not be replaced.
Advantages
1. Short filtering time
With the increase of filtra了鐘tion time, the filter cak務好e grows slower and slower. 去在In order to make the residual humidity 計南in the filter re師能sidue low, the filter plate frame and 森坐the box filter plate need a大男 longer filtering近讀 time; The use of JVK diaphragm f也紅ilter plate can 公放greatly reduce the filtration習制 time. The required residual humidit樹生y is achieved by影都 mechanical extrusion 術拿of the elastic diaphragm.
Residual humidity after讀國 filtration of diaphragm filt動這er plate:
A= diaphragm plate filtr城些ation end point
B= end point o錢靜f wing filter
C= residual humidity afte拍校r extrusion of 雨電diaphragm filter plat煙校e
A 'and C' are differe一朋nt possible outcomes depending on the上厭 operation
Suitable operation point熱了 A can be determi紅答ned after several filtrat的頻ion cycles.
2. Short washing time
The use of common filter el用吃ements can cause uneven 亮嗎cake formation, such as uneven wa笑醫shing due to wr票市inkling or crackin音風g. The JVK diaphragm filter plate個畫 avoids this unevenness due to the l物從ight pressure of the diaphragm durin白低g the washing process. 內銀Because of the uniform capillar吧短y structure formed in th答街e filter cake, the海子 washing effect is very goo明房d, and the consumption of wash朋妹ing liquid can be gre商也atly reduced.
3. Low residual humidity
The high pressure街知 filtration required in t技吃he filtration process is replace醫照d by a high elas遠熱tic membrane extr相跳usion process on the filter ca美黃ke. The extrusi生工on process is not al土得ong the direction of 個山the filter surface, but acros樂很s the filter surface. In a sh道樹ort time, the r動謝esidual humidity in the那報 filter cake decreas著道ed significantly, and the 拍黑filtrate outflow in事睡creased significantly. The benefits are購科 as follows:
It saves energy costs
A special vacuum process results in 身雪a solid content of 到嗎almost 100%
The blow-drying proces年校s is shortened
The filter cake sticks友外 less to the pr湖風ess cloth
The discharging time of filter ca兒厭ke is obviously 錢站shortened
The filtering pr嗎說ocess can be automated
Lower pump costs
Because the filter數月 cake is compact and dry, the t窗書ransportation cos吧慢t is reduced
Savings in storage costs
4. Diaphragm replaceable
The diaphragm can be e關員asily replaced inside or outside the fi一林lter press. If 有年the diaphragm is damaged o嗎很n either side of the窗的 traditional diaph的熱ragm plate, the entire雜畫 diaphragm plate should be rep一商laced. Diaphragm plate is a 姐短moving part of the plate, the 城一maintenance costs化司 need to be considered. The 鄉路removable diaphragm plate on either下風 side can be replaced信西 separately, and the core plat相上e continues to be used, greatl刀照y reducing maintenance and repl兵熱acement costs.
5. The closing force of 弟火the filter press does not dire黃熱ctly act on the diaphragm
The diaphragm edge exte學水nds only to the seal of 兒人the diaphragm plate core plate i湖數tself. Therefore, the c匠空losing force of 但腦the filter pres吃做s does not act on the diaphragm, but o還工nly on the sealing surface of the filte筆湖r plate core plate.
6. High elasticity of the diaphragm
Because of the good elasti村議city of the membrane, the membrane 說嗎can adjust itself without permanen照體t deformation for the uneven filter 亮鄉cake surface formed 術睡during filtration and the filte還唱r cake membrane with differ秒商ent packing density. This featu會會re ensures even and good ca很吃ke extrusion. JVK diaphra校空gm filter plate pressure up to 60ba計民r, to meet a va鄉熱riety of industrial懂跳 applications.
7. Even in the cavity st湖雨ate, the diaphragm movemen湖媽t will not be out of orde靜水r
The diaphragm is held in plac少土e where there is no stress. The >習錢; diaphragm can be squ老來eezed into the cavity w店計ithout failure,低會 regardless of the 醫大chamber depth.
The diaphragm filter plate of 暗山JVK has no bolted connection and is com草來pletely sealed by the關謝 rubber diaphragm itself. E哥電ven if the filter press is turn習這ed on when pressur喝什e is applied in the光媽 chamber of the diaphragm chambe村關r by mistake, the diaphragm 中站on the JVK diaphragm plate wi資視ll eject the filter pl黑的ate according to城就 the pressure to release the pressure, 他低and only need to be newly inst信路alled. The traditional di有亮aphragm plate is usually welded or bolt志高ed, which inevitably causes damage.理拍
8. There is no time limit for d計市iaphragm movement
In some cases, the gradual in人從crease and decrease of press機喝ure during feeding, washing and pre笑照ssing can be neglected. This process ca了鐵n be optimized with JVK d業器iaphragm plates.
9. The filter plate system h爸跳as good tightness
The filter plate core plate 暗通sealing process is performed in a女刀ccordance with the German in自笑dustry standard DIN 7129. The di白林aphragm is secured on th到場e periphery, so t男分he chamber seals very well. T錯拿he CGR design s農明tructure is a completely請子 sealed structure of 也雨the JVK diaphragm filter件微 plate.
10. Large filtrate outlet passage sec我城tion
The diameter and number of fil紙高trate outflow channels from the filte她弟r surface to the core of the filte嗎綠r plate are set according 雨謝to the requirements of the appli但畫cation. The diameter of the 嗎公outlet channel can be up鐘地 to 10mm, so the filtr電員ate discharge can be la說跳rge, without solid particles or crysta紙子ls blocking the outlet channel.
11. Wide range of applicat靜玩ions
The raw materials used at JV小們K ensure that the product can b呢花e used in almost all industries愛新 and can be adapted to each specific w市化orking condition. With商你 diaphragm made of special el為知astomer and diaphragm p信黃late core made of special ma吧冷terial, JVK diaphragm plate can be 男妹used for:
The temperature ranges from -2雜就0°C to +140°C
Filtration pressure up to 15bar
Press pressure to at least 25bar
Extreme temperature chan理笑ge (sudden change要什 in temperature)
Special chemical requirements
12. High safety of diap北為hragm system
There is no screw or民資 welded connection b城費etween the diaphragm and the sealing su笑照rface of the core plate. T秒店he pressure of the extruded media農場 behind the diaphragm can到河 only be maintained by a closed filt近歌er press. If the filter press is open o空森r just opened, but there is pr金空essure in the diaphragm, the diap到西hragm will immediately move a日男way from the fixed groove, resul北對ting in a non-dangerous release of pre市大ssure without damaging the di去身aphragm. The cost 靜舊of security maintenance has相購 been significantly reduced.
