The new des器個ign makes the rubber diaphragm 友筆tympanum more su多人fficient, and the pressure and a話事ir volume used are relat好黑ively small. Under the same air source機商 air volume, the rubber diap黑白hragm The tympanic membrane is th小相ree times that of the polymer 影還diaphragm tympanic membran美答e, which can grea笑子tly reduce energy consumption.
Polymer elastomer diaphragm filter土機 press is used in strong acid, strong a門件lkali and organic solvent 們冷materials, with relatively be商區tter performance and longer service區照 life. Its pressin章水g forms are divided in些綠to gas (air) pressing and liqui務冷d (water) pressi爸線ng, which can meet the needs 她拿of different industries. The p民樹ressing components can be 村女configured with food 很電grade and ordinary grade according to土你 customer needs, an可費d the control can a說樹dopt PLC and man-machine 什讀interface. For general materials,的兒 after 3-15 minutes of 訊志diaphragm tympanu道美m, it can fully exert the 地現effect of dehydra白的tion. For some sp說木ecial materials, it is also po大書ssible to use the staged p錢答ressing method of男看 low pressure pressing followed by得間 high pressure pressing.
The diaphragm filt窗姐er press realizes a highly efficient就明 dewatering filtra還熱tion process, and 對術can ensure that the filte山我r press exerts a 就船good filtering ef愛對fect, greatly reducing the water co能木ntent of the filter ca朋村ke. After the feeding間去 process is completed, 做懂the filter cake is pressed to花鐵 improve the dehydration 醫我efficiency of the whole machi校喝ne, the dryness of 光明the filter cake is暗們 increased, the pollution is reduce山爸d and the labor is reduced, and eve歌家n the drying pro時農cess can be elimin林謝ated in some processes.

Working principle
The main difference between d討少iaphragm filter presses 為做and ordinary box filter pr學子esses is that an elastic 為雨membrane diaphragm plate 電文is installed between the fi雪理lter plate and the f看一ilter cloth. During the operation船刀, when the feeding is completed, the hi民報gh-pressure fluid medi線跳um can be inject舊好ed between the filter plate少分 and the diaphragm. 城章At this time, t間問he entire diaphragm will swell 要船and press the filter要湖 cake, thereby achieving further deh嗎空ydration of the 聽筆filter cake, that is, squeez弟生ing and filtering.
The first is positive pr好資essure and pressur草黑e dewatering, also known看是 as slurry dewatering, that is, a cert南朋ain number of filter 習拿plates are closely 唱得aligned in a row 工兵under the action of strong mechan時文ical force. A filter chamb間技er is formed between the filter plate s視公urface and the filter plate surface. Th秒頻e solid part of the filter materi美睡al that is sent門跳 to the filter chamber under positive 個算pressure is trapped by the filter med線務ium (such as filter cloth土上) to form a filter cake, and 有子the liquid part passes through 公樂the filter medium and is di見上scharged out of the filter chamber火聽 to achieve the 什外purpose of solid-liquid separ北筆ation. With the明火 increase of positi行請ve pressure, solid-liquid sep行愛aration becomes more thorough, 動要but from the pe著森rspective of energy an請我d cost, excessively high positive說河 pressure is not cost-effective.
After the pulp is d東吃ewatered, a filter p兒作ress equipped with a rubber squeeze 日制film is used. The comp務微ressed medium (such as g購火as and water) enters the船藍 back of the squ快老eeze film to push the squeeze film t放舞o further dewater the squeeze fil靜得ter cake, which is called squeeze唱資 dehydration. After the pulp is dew街務atered or squeezed,玩多 the compressed air e城藍nters one side of the filter 她樂cake and penetrates the filter慢答 cake. It carries liquid moisture街劇 from the other side of the fi志算lter cake through 玩醫the filter cloth and 什志exits the filter room. If filter南些 cloth is applied 用農to both sides o拿冷f the filter ch物木amber, the liquid part can be evenly也暗 penetrated through the filter cloth on你她 both sides of 我鐵the filter chamber and 爸白discharged from the f煙大ilter chamber, so that the filte匠上r chamber is dehy答到drated on both sides.
After the dehydration is co拍人mpleted, the mechanical pr些醫essing force of the filter pla中水te is released, and the single pi請音ece of the filter plate is gradua到說lly opened, and th風多e filter chamber is o議海pened to perform cake un那相loading as a main work cycle. Depend草林ing on the nature of t對校he material being filtered, the filter說快 press can be eq來綠uipped with feed dewatering, 坐用squeeze dewatering, wind-blown dewat靜問ering, or single or double-sided dewate微輛ring, the purpose 人作of which is to reduce th木了e water content of th匠關e filter cake.
