Belt filter press product introduction
Belt filter press It is a water treatment equipment successfully developed after introducing technology from the United States through digestion and absorption. It can continuously press and filter a large amount of sludge. The product is made of high-strength materials and has the characteristics of large processing capacity, high dehydration efficiency, and long service life. It is widely used in solid-liquid separation in various industries. The bearings it is equipped with have long service life. At the same time, it uses high-quality filter belts to completely ensure the performance and quality of the filter press.
Working principle of belt filter press
Belt filter press is divided into three steps for filtration and dehydration functions
Gravity dewatering area
The sludge of the wastewater treatment plant is processed After being pumped into the sludge stirring tank and mixed with the polymer flocculant, the fine suspended particles in the sludge are formed into larger latex-like particles through the bridging effect of the polymer flocculant, and then stirred by gravity flow. The upper end of the tank overflows into the subsequent pressing and dewatering operation.
, Pressure dehydration zone
After the sludge enters the pressure dehydration zone from the gravity dehydration zone, the upper and lower filter cloths begin to gradually squeeze the sludge to dehydrate.
, Pressurized dehydration area
The sludge moves with the filter cloth into the pressurized dehydration area. Between the six vertical rollers, the pressure gradually increases from large to small according to the diameter of the rollers. With the large configuration, the shear force generated by the upper and lower filter cloths on the sludge due to the changing of the upper and lower positions between different rollers squeezes out the capillary combined water (r) in the rubber sludge to produce drier sludge. cake.
Advantages of belt filter press
Automatic control, continuous operation.
, low energy consumption and long service life.
, high dehydration efficiency and high solid content of mud cake.
, easy to manage and easy to maintain.
, low noise, less chemicals.
, economical and reliable, with wide application range.
Belt filter press performance
Scientific design and reasonable layout ensure that the filter press has high dehydration performance. The main dehydration pressure roller adopts a perforated design, which not only increases the processing capacity, but also The sludge can be dewatered on both sides at the same time. Both sides of the filter belt are quickly dehydrated during the filtration process, shortening the dehydration time. The arrangement of smaller pressure rollers at the back and the change of the contact angle of the filter belt ensure the maximum pressure and shear force. The best combination can greatly improve the solid content of the mud cake and the dehydration efficiency.
Features of belt filter press
The tension of the filter belt is realized through the inflated cylinder, so that the entire filter belt maintains constant tension, and at the same time, the tension will not change due to changes in the feed amount. Easy to operate and manage, the filter press has an air pressure control system that automatically detects the position of the filter belt on the pressure roller and automatically corrects the deviation. The wide filter belt filter press is also equipped with an automatic sludge feeding device to ensure that the sludge enters the filter evenly. belt, thereby improving filtration efficiency and extending the life of the filter belt.
Belt filter press structure
The belt filter press has two filter belts and an extended gravity dehydration zone before the normal pressure dehydration zone. This unique structure not only improves dehydration efficiency but also reduces chemicals and greatly reduces energy consumption.
Belt filter press operating procedures
Preparation work
Please read this manual carefully and understand the operating procedures and methods described in order to skillfully operate the dehydrator and its assembly components.
b. Check whether the belt filter press and its components are completely in good condition, and confirm that no other debris remains on the filter cloth and rollers.
. Check the reducer oil level.
d. Check whether the position of the filter cloth is correct.
Check whether the scraper is in proper contact with the filter cloth.
Check whether the tension of the upper and lower filter cloths is appropriate and adjust it to the appropriate tension.
, check the air compressor and adjust the air pressure of the machine.
, start working
, start the control valve of the air storage tank of the air compressor, and send the pressurized air to the air pressure control unit.
b. Adjust the air pressure to set the filter cloth tension. When pre-adjusting, be careful that the tension telescopic frame does not touch the frame.
. Move the filter cloth offset sensing device slightly by hand to check whether the cylinder operates normally. In addition, test whether the emergency stop switch function is normal.
d. Start the filter cloth washing pump, and check whether the water volume and water pressure of the pump meet the requirements (water pressure: /m).
Then start the belt filter press and check whether all equipment is normal. operation.
, start the sludge supply pump.
If the filter cloth deviates and cannot return to its normal position, please stop operation immediately.
h. Remember that if the tension on the filter cloth is not properly maintained, the filter cloth offset control system may not be able to perform its function.
, stop working
, turn off the sludge supply pump.
b. Next, let the belt filter press run for at least 10 minutes. While the belt filter press is still running, the filter cloth washing pump and sludge conveying device need to continue to operate until the residual sludge can be completely separated. Belt filter press and clean filter cloth.
After making sure that the sludge cake is completely separated from the belt filter press and that the filter cloth and rollers have been washed, turn off the belt filter press, washing pump and sewage cake conveying device.
Note: After stopping operation, if the belt filter press is not operated for a long period of time, please relax the tension of the filter cloth. (Before restarting the machine, please do not forget to adjust the tension of the filter cloth).
