A preprocessing stage, the solids content of the original slurry is generally low, must be the use of gravity sedimentation or other means to improve the concentration of the slurry, in order to reduce processing costs. The common pretreatment belt filter: the concentrated sludge and polymer flocculant mixing materials flocculant effect of fine particles aggregate, shape, and preliminary precipitation, Sludge Dewatering ready condition.Second, the gravity dehydration stage, sludge added after the flocculation pretreatment belt filter by filtration belt, they wear under the effect of gravity, of the free water outside the floc filter belt was filtered off, reducing the sludge containing water.Third, wedge preload dehydration stage, sludge after dewatering of gravity began to enter the wedge squeezed section belt filter filter band gap narrowing, applied extrusion and shearing of sludge, the sludge again dehydrated. After this stage the fluidity of sludge is almost completely lost, thus ensuring under normal circumstances will not be squeezed out of the sludge in the dewatering section.Dewatering stage, the sludge after the well-designed press rolls Department of repeated extrusion and shearing off a large number of capillary action of water, sludge moisture gradually reduced, the formation of sludge cake, in the re-election of belt filter machine filter with separate at the cake discharge scraper scraped, the filter cloth cleaned after the discharge into the next cycle.

belt filter press structure is compact, innovative style, easy operation and management, processing power, low moisture content of the filter cake, the effect is good.

Compared with the same type of equipment has the following characteristics:1, the first gravity dewatering section is inclined so that the sludge from the ground up to 1700mm, the sludge in the gravity dewatering section height increased and the gravitational dewatering capacity.2, gravity dewatering section, the first and second gravitational dewatering section of the total length of 5m, the sludge before pressing sufficiently dehydrated to lose fluidity. At the same time, the gravity dehydration segment also set the Reverse special institutions, wedge-shaped, the role of the press "S" to get the lowest water content of sludge cake.3, the first dewatering roll "T" type sinks, so that the large amount of water after pressing to rapidly discharge, thereby improving the dewatering effect.4, the belt filter press filter with a deviation has automatic control device, the filter belt tension and filtered with movement speed can be freely adjusted, easy operation and management.5, low noise, no vibration.6, the belt filter press for chemical drugs less View Details

Sludge under out: Domestic pressure filter structure is sludge from the filter press upper into filter press, and finally from the filter press the lower part of the mud after pressure slag barrel originally pressed dry sludge water tray overflow water wet sludge reach pressure dry, the impact of the effect of the use of a filter press. Filter Press overcome these shortcomings, the use of sludge on the avoid the sludge would have been pressed dry sludge overflow water dish to get wet, and greatly improve the use of the effect of the filter press. 2, the whole machine is made of 304 quality stainless steel, one-time investment, long-term use. belt filter press are installed in serious environmental pollution, and acid-base properties of relatively large, ordinary carbon steel material to do the anti-corrosion treatment, but are unable to bear the impact of the harsh environment, over a period of time will be born rust, greatly shorten the life of the machine. The filter press 304 quality stainless steel material, to overcome the above disadvantages, durable and will never rust, nice machine, greatly reducing maintenance trouble, comply with the requirements of environmental protection. 3, an octagonal stirring dehydration cage device: This device is mainly applied to the material before the belt filter press dewatering system, the structural principle is found based on the actual use of the process shortcomings, consider focusing on the material before extrusion into the filter chamber, the high moisture content of the material through the octagonal stirred dehydration cage means, so that the material moisture is reduced by 50% or more, the volume of the material is also correspondingly reduced by about half. So, enter the filter with extruded materials be doubled, the the filter belt speed can also be a corresponding increase in the mud filter press. Utility model conventional belt filter press, compared to the same filter width, and its efficiency is more than doubled, while also saving energy consumption, reduce the cost of equipment. 4 the preservative-axis of a belt filter press, sets of transmission structure: This structure is found shortcomings in the actual process of using the focus to consider the transmission part of the anti-corrosion material selection problem, the entire structure completely solve the problem of corrosion, the drive shaft is made of high quality stainless steel sleeve optional PTFE material. The two materials of the shaft and sleeve never rust. Wear factor is very small, slow operation and extended service life. No mechanical rotating sound of the collision, in a slow operation, no noise, and conforms to the requirements of environmental protection. 5, a single active rubber tire drive shipped agencies: Seen from the utility model of the principles of the structure and use, there are the following advantages: the main roller and the driven roller without the same diameter, the line speed of its operation depends on the initiative rubber tire, in fact, is a synchronous operation, also played a belt calender filtered results without using sprockets and a chain drive, to reduce the material and parts, the overall structure is simple, the installation and maintenance is extremely convenient, extend the service life of the machine, the noise generated when the machine operation is particularly small, comply with environmental protection requirements. Avoid two different rubber tire diameter, filter with folding phenomenon appears to shorten the service life of the filter belt. 6, the machine clean and beautiful, in line with the requirements of environmental protection: The sides of the chassis plate is fully enclosed with ABS board, avoid sludge, sewage spilled out, polluting the environment, and the entire machine is clean and beautiful, to comply with environmental requirements.
