Megalith, Filter press - MATEC INDUSTRIES

Mechanical dewatering with high-pressure technology.

Dewatering by high/pressure technology (HPT) means a higher force to drive or compress the filter cake, achieving a dryer filter cake as low as 10% residual moisture, giving back up to 98% water to the process.

The NEW HPT30 bar allows you to filter at an even higher pressure than before.

The MEGALITH with its simple design, consisting of 6 pushing type hydraulic cylinders, used to close the filter press, disturbing the closing pressure evenly, and open the filter press of which the first 10 plates are shifted.

Simple also means the filter press consists of recessed chamber plates, linked together by chain, and a shaker system consisting of pneumatic cylinders, all standard with the MEGALITH filter press.

Structurally sound and all put together by a fixed carbon steel head, end and 4 lengths of double welded rectangular tubing, for side beams. Making this filter press the only filter press capable in reaching 30 bar safely.

With the demand for filtration technology increasing and the material to be filtered becoming more challenging, the need for NEW technology becomes more prominent.

By creating the BIGGEST filter press out there that makes use of the Highest feed pressures currently possible, we are solving dewatering problems by giving a single solutions to the solid – liquid seperation challenges.

Air Gasser® Automatic Shaker

Pneumatic system to guarantee the detachment of the filtering cloth panels created with a series of high efficiency pneumatic cylinders. They lift a stainless steel bar by means of special pivots and then release the plate in order to give it a suitable ver- tical stress. Our shaker does not wear out and guarantees an efficient vertical shaking of the plate and the complete detachment of the mud cake. Protection and safety systems :

  • Emergency ropes (Standard equipment for every Filter press)
  • Stainless steel cover AISI 304 for machine protection and safety.
  • Photoelectric barriers.
  • Safety gates.

Cake Dryer

The Cake-Dryer is a 100% automatic system for the drying of the cakes of mud through the use of compressed air. The system is similar to that of the Core-Blow; the jet of compressed air is blown into the central hole of supply of the plates, thus allowing a drying of block of 20 plates, to have a final cake completely dry.

Cake Washing

A close circuit system for special mud with chemicals. It usually workstogether with the membrane plate system, allowing a clean water flowinside the plate chambers before cakes are discharged. This processrinses the cakes, to lower chemicals’ level under the “special mud” threshold.

REQUEST A QUOTE

Core Blow

Core blow system is projected to clean the core at the end of the filtering process from the residual unsqueezed mud gathered in the diffusion conduit through the plates. The Filter press is equipped with an air conduit in the mobile plate to blow, at the end of the filtration process, the residual liquid mud back out of the plates. An appropriate valve system let the blown mud bypass the mud pump and be discharged in the mud tank again.

Drip Tray

During the filtering cycle a few drops of water can escape from the cloths, especially if these are new, so to avoid that fall of water on the mud cakes already discharged, Matec has created two particular types of drip. The “drip tray” system consists in a tray, composed by one or two tanks shifted, which occupies the part underneath the filter press during the filtering phase, then collecting the drops of water that escape; once the filtering phase has finished, the tanks are then moved by a motor to allow the discharge of the cakes. The “bomb doors” model has two doors that rotate to occupy the space below the filter. They are positioned with an inclination that allows them to collect the water that comes out, and then redirect it to lateral drips, where it will be sent back to the waste water tank.

HPT 16/21

Matec filter presses have been created for the aggregates sector where HPT is essential for obtaining excellent results with difficult muds. While our competitors come from sectors such as olive oil, marble, and chemi- cals. HPT is more expensive, it needs MORE QUALITY and better components:

  • Bigger piston bore
  • Bigger oleodynamic power unit
  • More iron for the frame structure

Real Washing

The filter press can be equipped with an automatic washing system forplates and cloths. The system is composed by one valve and one system of pipes on the mud head side of the filter press, and discharging val- ves on every single plate. The feeding pump sends clean water to wash the residual mud. The sytem washes the plates 20 by 20. The frequency of the wa- shing cycle is set through the operator panel.

REQUEST A QUOTE

Robo Wash

The RoboWash washing operation is a fully automated cloth washing system that can be put into operation at the touch of a button. The high pressure sprayer located at the end of a drop down curtain, slides between each plate and applies high- pressure wash water to the full area of the filter cloth, dislodging and cleaning any build up of dirt on the filter cloth.

Squeezing Membrane Plates

The membrane plates are special plates with one internal chamber and one membrane. The membrane allows a bettermechanical squeezing of drying mud cakes. Basically, the membrane is inflated with water and grows in volume pressing on the sludge whi- ch is pumped into the chamber. A non-fixed volume is the main difference with standard plates. The special plate, together with the drainage system, guarantees a dryer final product and a more efficient filtration cycle. Also the discharging of the cakes is bene- fited. The material for the membrane may vary using different techno-polymers to meet customers’ requirements and depen- ding on the material to be treated, usually it is a variety of polypropylene.

Tilt Sensor

This system consists of proximity sensors, upper and lower ones, to control the tilting of the last closing plate. In the software that manages the filter press you can set the delay time between the two sensors. If the second sensor activates within the set time after the first one, the machine can continue its cycle normally. Otherwise an alarm will go off.

REQUEST A QUOTE

Torbidity sensor

It is placed in the freshwater storage tank, turbidity meter consisting of a candle measuring machine (sensor) immersed in water, with dissolved particles. Based on the feedback that is obtained from the measurement system, it is possible to determine where to direct the flow of water. Through pre-set values, if it is detected a too high level of turbidity, the system switches two valves and diverts the flow of water from the fresh water tank to the waste water collection tank, to resubmit the water to the clarification phase.

TT2 Fast System

The TT2 System is patented by Matec to solve the problem of sludge discharging opening and closing dead time in filter presses. Thanks to this system that reduces also the length of the machine, the process of plate discharging has decreased from the usual 15/20 min to 3 min for 150 plates. This system guarantees also a 30% increase in productivity and a reduction in operating and maintenance electrical costs, in addition to an easier use of the machine. The TT2 works by opening the main cylinder just once, then it closes, in order to open the first 10 plates. The quick opening of the plates is used to open 10 plates at a time through the back and forth shifting. The two oleodynamic cylinders “TT2 Fast”, installed on lateral bars and provided with mechanical modules. The opening of 2 cylinders works at high speed through the oleodynamic power unit.
