Belt Filter Press

The stomach press channel press is made out of stomach plates and chamber channel plates organized to frame a channel chamber. The slurry is taken care of into the chamber under the strain of the feed siphon, and the solids and fluid in the slurry are isolated through the channel medium (channel fabric), and when the solids in the slurry structure a cake, air is then passed to the stomach to completely press the solids in the chamber.

Stomach press channel presses lessen the water content. This machine is especially valuable for the filtration of thick materials and for clients with high water content necessities. The channel plate is made of supported polypropylene and the stomach is decorated with the polypropylene plate, which is solid and dependable, difficult to tumble off and has a long assistance life. It is outfitted with different wellbeing gadgets to guarantee the security of the administrator and the typical activity of the channel press.

The suspension is siphoned into each shut office of the channel press, and under the activity of the functioning tension, the filtrate is released through the channel layer or other channel materials through the power source, while the channel buildup is left in the edge to frame a channel cake, subsequently accomplishing strong fluid partition.

The stomach press channel press is utilized for strong fluid detachment of different suspensions and has a wide scope of utilization, appropriate for drug, food, compound, natural security, water treatment and other modern fields.

Belt channel press for cows conceal tannery wastewater treatment project

A cowhide tannery in Jiangsu Province is one of the bigger Membrane Filter Press cowhide tanneries in China. Its wastewater release is around 1800m3/d, with high convergence of natural toxins, suspended matter and harmful substances like weighty metal chromium, and has a grimy appearance and terrible smell. The undertaking has a unique sewage treatment framework, which involves synergist oxidation for desulphurisation prior to being released by coagulation and sedimentation.

With the improvement of neighborhood natural insurance necessities, the complete release from the first office was a long way from fulfilling the optional release guideline for tannery wastewater in the new GB8978-1996 wastewater release standard. Therefore, the proprietor appointed our organization to remodel the first wastewater treatment framework. After over four months of appointing, the framework is running dependably and the profluent is steady and up to norm, while the working expense has been altogether decreased based on persistent improvement of the working parameters.1 Source and qualities of the wastewater The tannery creation process is displayed in Figure 1.

The tannery wastewater chiefly comes from the readiness segment and the tanning segment, including the first calfskin washing water and corrosive filtering water containing high grouping of chloride, the solid soluble debarking and splashing debris wastewater containing lime and sodium sulfide, the blue chrome tanning wastewater containing trivalent chromium, the tea-earthy colored vegetable tanning wastewater containing tannin and gallic corrosive, the de-esterification wastewater containing oil and its saponification, the oil coloring wastewater and the flushing wastewater of each segment, and so forth Among them, the degreasing wastewater, the debarking and dousing debris wastewater and the chrome tanning wastewater are the most dirtied. The most genuine contamination is the degreasing wastewater, the debarking and dousing wastewater and the chrome tanning wastewater. The volume of tannery wastewater changes enormously with time, and is frequently released irregularly, during the pinnacle release time of 5h, the volume of release can represent 70% of the all out volume of release; the nature of water likewise shifts extraordinarily, the centralization of wastewater in this plant is high: CODcr=16000mg/l, Cr3 =800mg/l, S2-=300mg/l; when it is low: CODcr=600mg/l, Cr3 =2mg/l, S2-=10mg/l; blended wastewater: CODcr=600mg/l, Cr3 =2mg/l, S2-=10mg/l. =10mg/l; blended wastewater is soluble, poisonous, high substance of difficult to-debase substances, messy appearance, disagreeable smell, release is 1200~1800m3/d, water quality record: pH 8.5~10, CODcr is 5000~12000mg/l, BOD5 is 2000~6000mg/l, Cr3 is 80~180mg/l, S2-is 40~200mg/l, SS 3000~5000mg/l, Tss 8000~16000mg/l, chromaticity 120~300 occasions.

Establishment of the channel plate a) The head plate of the channel press has been introduced and fixed on the plug plate of the channel press. (manufacturing plant introduced) b) The tail plate is introduced and fixed on the strain plate of the channel press. (plant introduced) 4. Change of water driven framework a) Hydraulic oil of the necessary quality, separated through a 20μm screen opening and added to the oil tank to the maximum furthest reaches of the sight glass. b) Start the oil siphon to press the oil into the water driven chamber, right now the fluid level ought to be situated in the center line of the sight glass.
