best quality, good service, professional vacuum belt filter

Horizontal DU Rubber Vacuum Belt Filter Press is equipment using vacuum negative pressure as impetus to separate the solid and liquid. The Filter District is arranged levelly to sequentially finish the procedure of filter, rinse, dry and regeneration of the filter cloth with high efficiency, high output, good rinsing effect, low moisture, agile operation and low repair cost. It can be used to separate solid and liquid in the fields of metallurgy, mine, chemical industry, papermaking, food, pharmacy and environmental protection,especially for dehydration of gypsum in the processof smoke desulfurization

Horizontal Vacuum Belt Filters offer number advantages for process plants:

•High filtration rates and large tonnage capabilities

•Excellent washing efficiencies and lower cake moisture

•Long service intervals and low maintenancecosts

•Accomplish feeding, filtration, cake washing, sip up, cake discharge, cloth wash techniques operation continuously.

Structural Technical Features:

•Ring type rubber discharging belt is used with high tensile strength and long service life.

•Ring type abrasive belt is set between vacuum container and the rubber belt, water is used to airproof and lubricate which can keep stable and higher vacuum degree, good for stable operation state.

•Rubber belt is supported by air cushion or water to reduce the resistance and is good to prolong service life of the rubber belt.

•The whole structure adopts module design which can be consolidated freely, convenient for transportation and installation.

•Vacuum balance automatic discharging tank or steam-liquid separator is set to carry out zero potential difference automatic discharging or high potential difference discharging to satisfy requirements from different working states

•Air chamber type automatic deviation correction device is set to assure stable running of the filter cloth.

•The control system uses PLC technology to carry out PID regulation, provide safety guarantee of running and supervision of the procedure.

•The mother filtrate and others washing filtrate can be collected in different subsection. Meanwhile the washing can be in current washing and countercurrent washing way.

•It is convenient to remote automatic control and scene control for DCS.

Applications of horizontal vacuum belt filter

Typical applications for the horizontal vacuum belt filter include:

On the basis of introducing foreign technology of the same kind products, rubber belt vacuum filter is akind of highly efficient solid-liquid separating equipment through our research. It adopts settling vacuum chamber and the rubber belt moves on vacuum chamber. Vacuum chamber and rubber belt form a structure of moving and sealing. It in fact has realized continuous filtering, cake cleaning, residue unloading and filter fabrics cleaning and collecting the mother liquid and the cake cleaning efficient, low cake water, operation smart, maintenance simple and so on. Rubberbelt filter has experienced many times of improvement and perfection. The technical and quality have been the international advanced level. It has been widely used in sectors such as metallurgy, mining, chemical engineering, paper making, food, and pharmacyand environment protection.

Typical Process Chart

1. Vacuum Trip

Filtering trip beginning, pulp is uniform in filtering take, filter plate and filters synchronous forward movement, with the pulp of filter in vacuum suction operations under the action of slurry, until the vacuum dish to metal sensors, cut off the vacuum so far.

2. Return Trip

At this time the filter machine to continue at the same speed moved forward, and vacuum dish met contacts spacing device, vacuum switch valve action, filter plate to immediately release the vacuum, vacuum filter plate was delayed 0.5 seconds to return to cylinder quickly dragged back to the original location, so that the cycle of be vacuum suction filter process.

3. Washing, Blot, Discharging Slag Process

Filter the pulp with the vacuum suction filter, in order to better solution from the filter cake. Will filter cake wash, the filter cake can small mother content to 0.1%. after washing the filter cake sucked dry area blot, filter cake content and varies according to the material, the filter cake of washing, sucked dry by head round after radius of change and the song filter scraper will the dissection of the unloading.

4. The Cloth Wash Regeneration

Filters is equipped with high pressure flushing device, since filters filter cake after stripping into cleaning link, to prepare for continuous operation of equipment.

Vacuum Switch Valve Working Principle

1. Function of Vacuum Switch Valve:

Vacuum switch valve is PBF type consecutive vacuum belt type filter machine level one of important parts. Through the vacuum switch valve two-way switch, make continuous vacuum belt type filter machine level filtrate with control ruled out. Filters dragged to the vacuum filter plate with speed homonymous moved forward, with the pulp of filter under the action of forces in vacuum, vacuum filter plate until met trip contacts spacing device, and the gas control device reversing, this time the vacuum switch valve action program, turn off the vacuum channels open air channel vacuum dish to immediately release the vacuum and be returned back to the original starting location in drag cylinder, and at the same time limit contacts to signal, sort switch valve recovery procedure action, turn off the air, open channel vacuum, vacuum system through, so go round and round switch procedures.

2. Working Principle:

When compressed air cylinder head into the cylinder by the intake, the pistons downward motion, drive small seal seat to shut down and seal under vacuum orientation float, opened the atmosphere, completed the first switch program action, vacuum filter dish to return to the starting position, the trip contacts spacing device signal occurs, compressed air through the inlet into the cylinder, promote small pistons uplink, when compressed air forces greater than the vacuum suction, piston driven up small seal seat on vacuum, vacuum chamber and automatic vent connected tank, filtered. So go round and round, and atwo-way switch.

Automatic Liquid Discharge Can Work Principle

It is automatic liquid discharge under vacuum conditions of gas-liquid separation common equipment. It can be divided into leverage buoy type and gas-liquid conversion separated, lever buoy type flexibility gas and liquid separated conversion than poor, so gradually be separated out gas and liquid, gas to liquid conversion separated by tanks, sealing head, supporting feet, gas to liquid import, discharge valve of liquid.

Work initial state, liquid discharge valve is closed; filling body in avacuum state, gas to liquid mixture from import is tangent filling into the body. Liquid centrifugal force of its own gravity by rotation and with gas separation, when vacuum filter plate and switch valve borrow trip contacts spacing device cut off a vacuum, air through the imported into irrigation body, make the body cavity and filling liquid discharge valve of air pressure in balance.

Because the body weight of filling liquid and gas pressure than the pressure of the atmosphere, liquid discharge valve opens the liquid discharge irrigation outside, so go round and round. Complete vacuum system automatic liquid discharge process.
