First, an overview
Belt filter press is the introduction of technology from the United States by the digestion and absorption, the successful development of a water treatment equipment, continuous pressure filtration of large amounts of sludge, the product uses high-strength materials, with a large capacity, high dewatering efficiency, the use of long life and so widely used in solid-liquid separation of the various sectors, the long life of bearing its configuration, while using high-quality filter with fully ensure the performance and quality of the filter press.
Second, the principle
Belt filter press is divided into three steps to carry out the functions of filtration and dehydration:
1, gravity dewatering
Pumped into the mixing of the sludge mixing tank with polymer flocculant (polymer), the wastewater treatment plant sludge, the sludge in small particles of suspended like latex formed by the bridging role of the polymer flocculant (floc) like larger particles, then a gravity flow to the top by the stirred tank overflow into subsequent dewatering operations.
2, pressure dehydration
Sludge pressure dehydration District by gravity dehydration District into the upper and lower cloth began to squeeze the sludge dewatering.
3, pressure dewatering zone
Sludge pressure dewatering area with the cloth move into the six were vertical like the wheel, according to the wheel diameter by the large and gradually smaller, gradually increasing pressure from small configuration, with the up and down the cloth in a variety of wheel shear forces generated between transform the upper and lower positions of sludge, the floc mud capillary water (capillary water) squeezed out to produce a drier sludge cake.
Third, the advantages
1, automatic control, continuous.
2, low energy consumption, long service life.
3, dehydration, high efficiency, mud cake solid rate.
4, easy to manage, easy maintenance.
5, low noise, less chemicals.
6, economical and reliable, and a wide range of applications.
Fourth, the performance
Scientific design and layout, to ensure that the filter press with high dewatering performance, the dehydration of the pressure roller is a hole design, not only the processing power increase, and the sludge on both sides at the same time dehydration, filter belt both sides of the rapid dehydration in a filter press process, shorten the drying time, behind the smaller the pressure roller arrangement and filter with a contact angle change to ensure the best combination of pressure and shear forces, thus greatly improving the cake solids rate and dewatering efficiency .
Fifth, the characteristics of
Filter belt tension by a pneumatic cylinder, so that the entire filter with maintaining a constant tension, and will not cause tension changes due to changes in the feed rate, easy to operate and manage, filter automatically detects the filter band pressure roller on the location and automatic correction of the compressed air control system, and comes with automatic sludge feed device to ensure wide filter belt filter press sludge balanced access to the filter belt, thereby enhancing the filtration efficiency and extend the life of the filter belt.
Six, the structure
Belt filter press with two filters, there is a longer gravity dehydration prior to the normal pressure dehydration, the unique structure not only improves the efficiency of dehydration, reduced chemicals, and significantly reducing power consumption.
7, the operating procedures
1, the preparatory work
a Please read this manual thoroughly and understanding described in the operating procedures and methods to skilled operation dehydration and its assembly components.
b, check the belt filter press and its components in good condition, and confirmed that no other debris left in the cloth and rollers.
c, check the reducer oil level.
d, check the filter cloth location is correct.
e, check the scraper and the cloth of appropriate exposure.
f, check the upper and lower cloth tension is appropriate, and adjusted for proper tension.
g, check the air compressor and adjust the machine's air pressure.
2, begin work
start the air compressor air tank control valve, the pressurized air into the pressure control unit.
b, adjust the air pressure to set the tension of the cloth, pre-adjustment, pay attention to the tension telescopic frame can not hit the rack.
hand slightly offset sensing device of moving cloth, to view the cylinder will operate normally, In addition, test emergency stop switch function is normal.
d start the filter cloth washing pump, and view the water pump and water pressure to meet the requirements (water pressure: 4kg/cm2).
e, and then start the belt filter press and check whether all devices are functioning normally.
f start the sludge supply pump.
g, if the cloth offset can not return to normal position, immediately stop operation.
h Remember that if the tension on the cloth not properly maintained, cloth offset control system may not be able to perform its functions.
3, stop working
a close the sludge supply pump.
b, then let the belt filter press operation for at least 20 minutes, the operation of the belt filter press, filter cloth washing pump and sludge transportation device should also continue to maintain the operation, until the residual sludge from the belt pressure filter machine and wash cloth.
c, and then determine the sludge cake is completely out of the belt filter press, belt filter press cloth and rollers are cleaned, then turn off the washing pump and sewage cake delivery devices.
Note: When operation stops for a longer period of time not to operate the belt filter press and filter cloth tension, then relax. (Before the reboot operation, do not forget to adjust the tension of a good cloth)Eight,
