2.0快速型壓濾機結構型快速高效隔膜壓濾機由主機、液壓系統、電控系統、卸料機構等組成。主機由機架部分、濾板組件、濾板拉開合攏機構、濾板壓緊機構組成。

2.1機架機架是機體的主體結構部分，兩平行的主梁分別與固定壓板組件和后支架相連構成矩形框架，主梁用以裝配濾板拉開合攏機構并支撐濾板組件、壓緊機構、自動卸料機構等零部件。

2.2濾板組件壓榨濾板組件和過濾板組件交替排列在主梁上，在濾板過濾面覆蓋一層濾布，形成一個個過濾腔室，壓榨濾板組件中，濾板和濾布之間覆蓋有隔膜。過濾時，料漿在料泵壓力作用下，經固定壓板、進料濾板、活動壓板上的進料口進入各個過濾腔室，料漿中的液體借助入料壓力作用，透過過濾介質匯集到排液孔，經明流孔和暗流孔同時排出。料漿中的固體顆粒則被過濾介質截留在過濾腔室內形成濾餅。當物料充滿過濾腔室時，過濾階段結束，壓縮空氣進入隔膜與濾板之間，使得隔膜產生彈性變形擠壓濾餅，進行二次壓榨脫水。

2.3濾板壓緊機構活動壓板帶動活動油缸座及濾板初步合攏后，活動油缸座上個鎖緊油缸帶動滑塊組件伸出，限制活動油缸座后移。主油缸活塞桿伸出，壓緊濾板。電控系統自動控制液壓系統使主油缸、副油缸同時進入保壓狀態。當濾餅形成并壓榨脫水后，主油缸帶動副油缸、活動壓板松開退回，鎖緊油缸帶動滑塊組件縮回復位，濾板拉開合攏機構開始工作。

2.4卸料機構卸料油缸的伸出與縮回實現卸料大梁的上下運動。擺動桿上的濾布隨之上下移動，使濾餅脫落。

2.5液壓系統它是壓濾機的動力裝置，由油泵、液壓控制元件、液壓執行元件、高位油箱、液壓管路等組成。各執行油路均設有減壓閥，主油路設置系統溢流閥。2.6控制系統由控制部分、信號部分、執行部分組成，具備手動、自動化操作功能。

(1) The control part consists of programmable controller, programmable text display terminal and control panel, buttons, switching power supply, AC contactor and so on. It takes the programmable controller and programmable text display terminal as the core, and sends out action instructions to the mechanism according to the input procedure and the feedback information of the signalling system.

(2) Signal system main cylinder expansion and contraction limit; filter plate pull open and close limit; slider assembly lifting limit; hydraulic system oil pressure measurement and other sensors will be institutional action information and hydraulic system parameters feedback to the control part.

(3) the implementation of the part of the hydraulic station oil pump motor, electromagnetic reversing valve, pipeline system electronic control valves, etc., according to the instructions issued by the control part, to complete the action requirements of each step.

(4) Automatic operation During automatic operation, the control system starts the motor oil pump, and the motor runs without load. The control system issues a command, electro-hydraulic directional valve action, the main cylinder rodless chamber rapid action, vice cylinder from the high level tank oil replenishment with the action. The pressure of the hydraulic system rises after the filter plate is pressed, the system sequence valve opens, and the pressure of the main and sub-cylinder rises at the same time. When the pressure reaches the set upper limit value, the pressure sensor feeds back the signal to the control system, the control system sends out the motor oil pump stopping instruction, and the main cylinder is in the process of keeping pressure. When the pressure drops to the set lower limit value, the control system starts the motor oil pump again according to the feedback signal, until the pressure rises to the set upper limit value again. The feed pump presses the slurry into each filter chamber for filtration, and after the cake fills the filter chamber, the compressed air enters between the diaphragm and the filter plate for the second pressing and dewatering. At the end of pressing, the motor oil pump starts again, the electro-hydraulic reversing valve moves, the main cylinder rod chamber feeds oil, and the vice cylinder follows. Filter plate loosening, control locking cylinder electromagnetic reversing valve action, locking cylinder drive slider assembly reset, control a pull-open hydraulic motor electromagnetic reversing valve action, the motor through the drive chain drive movable pressure plate, movable cylinder seat moving pull-open filter plate unloading. Once pulled open in place, the control system to start the second pull-open hydraulic motor for the second unloading, the second in place, through the electromagnetic reversing valve reversing action, making the second pull-open motor reversal, feed filter plate drive filter plate three times pulled open unloading. After the end of unloading, start a pull-open motor reversal, drive the activity of the pressure plate, the activity of the cylinder seat and the filter plate together in place, the locking cylinder drives the slider assembly will be the cylinder seat locking, to complete a cycle of work, the motor oil pump stops working.

(5) Manual operation manual operation, through the control cabinet panel buttons step by step to complete the closure and compression, into the material filtration, pressing dehydration, grouped unloading unloading a complete stage of operation.

2.7快速壓濾機自控系統

(1) System configuration for the completion of intelligent control, the selection of programmable controllers. It is a module for road switching input and road switching output. Block for the road switching input, road switching output expansion module. Input signals are buttons, oil pumps and material pumps, conveyor operation feedback signals, valve feedback signals. Output signals are: indicator, alarm, intermediate relay for control (oil pump, material pump, conveyor, valve, etc.). It is a miniature programmable terminal of programmable controller, which is used for on-site monitoring in the control system of rapid filter press, real-time display of the working status of each process of the system, precise positioning of process alarms and faults, and setting of process parameters during automatic operation, etc. It also collects the external switching signals, which can be used for the control of filter press. It collects the external switching signals and controls the output signals, indicator lights, alarms or intermediate relays by running the control programme stored in it, so as to achieve the control of the field equipment and complete the control functions required by the process.

（2）軟件編制采用梯形圖編程語言，根據工藝要求首先在計算機上應用編程軟件編制應用程序，然后通過編程電纜與通信進行在線調試，調試成功后即可將程序下傳至。程序流程：初始化閥門!參數設定!手自動檢測!臨時停車檢測!故障檢測!油泵啟動!壓緊!保壓!補壓!入料!壓榨!反吹!卸料!復位。經過近運行，效果良好。
