Case description


铅酸蓄电池PE隔板混炼挤出成型生产线 900 水印.jpg


I. Raw material automatic feeding system:

Load the raw material UHMWPE, SiO2, carbon black, anti-oxidant and additive into the charging hopper, feed according as proportion measuring into weighing hopper by solid (powder, granule) weighing sensor interlock each motor driven of charging hopper, the special filling oil liquid is fed into liquid weighing hopper by liquid measuring pump, the control accuracy of solid and liquid weighing sensor is 0.5%, control system adopts Siemens PLC interlock control.

II. Twin screw extruder and sheet extrusion system:

Use twin screw extruder for compounding dispersing and extruding of the mixed raw material. The bed is movable bed, convenient for screw replacing and cleaning, equipped with liquid injection system, adding percentage of special oil can be modified on-line according to the process requirements. After passing through a filter, the melt is booster by a melt pump, and then evenly extruded to casting wide fabrics by the sheet die, and move into next step of sheet forming. 

III. Five-roller sheet forming unit:

5-roller calender to make calendaring, shaping and forming of the last sheet die casting melt. Use independent mold temperature controller to control the roller temperature by thermal oil, temperature control accuracy: ≤±1℃. Roller is driven by vertical reducer and speed controlled by inverter and interlock with PLC, hydraulic adjusting for the gap of roller, accuracy can be adjusted to ±0.015mm to ensure the uniform thickness of the PE separator . Through the trimming device, cooling conveying bracket, online thickness gauge, the forming sheet  is conveyed to next step by hauling machine .

IV. Deoiling tank:

Adopt special adjustable stainless steel tank body, the tank is separated to 7 pcs inner tanks, which is for storage of the TCE liquid according to the ladder in order to dilute the special oil step-by-step. Each inner tank is configured up and down rollers, down roller can be lifted up and down so that the sheet can be immersed into the TCE liquid along as the down roller after winding, it can control the sheet staying time in the deoiling tank by adjusting the lifting height to ensure the deoiling capacity meet the process requirements. The rollers are driven by reduction motor, transmitted by double row chain wheel and chain, speed controlled by AC inverter and interlock with PLC, ensure to be synchronous with the line velocity of the sheet, adjustable range of line velocity: 5~12m/min.

V. Drying tank:

Adopt by stainless steel tank. 16 big diameter rollers with heating are evenly distributed inside the tank. Each pair of heating roller configured up and down to heat the PE separator uniformly. Heating roller heat and volatile the TCE on the micro hole PE separator, the volatized TCE gas was pump into condensation adsorption device for online recycling. The rollers are driven by reduction motor, transmitted by double row chain wheel and chain, speed controlled by AC inverter and interlock with PLC, ensure to be synchronous with the line velocity of the sheet, adjustable range of line velocity: 5~12m/min. 

VI. Coating tank:

Adopt stainless steel tank, the coating is coated on the surface of the separator when the PE separator pass  through the tank, the roller is configured up and down inside the tank, down roller is with up and down movable adjusting structure to control the PE separator passing time to the coating tank to ensure the surface coating meet the process requirements. The rollers are driven by reduction motor, transmitted by double row chain wheel and chain, speed controlled by AC inverter and interlock with PLC, ensure to be synchronous with the line velocity of the sheet, adjustable range of line velocity: 5~12m/min.

VII. Coating drying tank:

 Adopt stainless steel tank, 14 pairs big diameter rollers with heating are evenly distributed inside the tank. Each pair of heating roller configured up and down to heat the PE separator uniformly to achieve the drying purpose of coating. The rollers are driven by reduction motor, transmitted by double row chain wheel and chain, speed controlled by AC inverter and interlock with PLC, ensure to be synchronous with the line velocity of the sheet, adjustable range of line velocity: 5~12m/min.

VIII. On-line infrared hole measure monitoring device:

The device is consisting of light source, CCD group, data processing unit, IPC, displayer and mechanical framework etc. The collected data by the CCD imaging sensor is displayed on the displayer after making processing and analyzing which for on-line detecting the pore diameter size and other defectives on the PE seperator. Light alarm to the micro hole on PE separator which is bigger than rated size(4μm) and make records at the same time and interlock with the PLC system. Quantity: 2sets. One is placed on the front of the entrance of deoiling tank, another is placed on the behind of the exit of coating drying tank.

IX. Electric cotnrol system:

Adopt Siemens PLC control system for interlock control of complete equipments. Control system gathers all kinds of data and provides HMI to make all kinds of information to be processed in real time, realize automation and informatization management. PLC interlock control range:  Auto feeding system, mixing system, twin screw extruder, 5-roller calender, deoiling tank, oven drying tank, coating tank, drying tank,  on-line infrared hole measuring system. PLC module is Siemens S7-1200 series, adopt 12” inches Siemens color touch screen.

X. TCE gas condensation recycling device:

Adopt condensation and deep adsorption integrated process, first condensate the mixed gas of TCE gas and air to -40℃, most of the TCE gas in the mixed air liquefied and discharge into oil storage tank after through oil-water separator, the residual gas mixture goes into the adsorption tank which filled with activated carbon to adsorb the remaining TCE, pump out the adsorbed TCE and then put into condenser to condensate into liquid to recycling and discharge the processed air into atmosphere.  Processing capacity of the device: 600Nm3/h, explosion-proof grade: dⅡBT4, TCE gas recovery≧95%.

XI. Oil separating device:

The collected oil from the deoiling tank and TCE mixture liquid go into the oil  special reaction kettle, reaction kettle is stainless steel, volume is 500~1500L, equipped with electric heating device and mixing blade to make the liquid heat evenly, use the characteristics that the boiling point of TCE is lower than oil, the reaction kettle equipped with vertical fractionating column for separating the volatile TCE gas and oil liquid. The separated oil goes into recycling tank, the TCE gas is recycled after condensation.
