Ease of use
The drum is supported by a large diameter trunion on the valve end and a bearing on the drive end
The drum face is divided into circumferential sectors each forming a separate vacuum cell
The internal piping that is connected to each sector passes through the trunion and ends up with a wear plate having ports that correspond to the number of sectors
A valve with a bridge setting controls the sequence of the cycle so that each sector is subjected to vacuum, blow and a dead zone
When a sector enters submergence vacuum commences and continues through washing, if required, to a point that it is cut-off and blow takes place to assist in discharging the cake
The valve has on certain filters adjustable blocks and on others a fixed bridge ring
Adjustable bridge blocks enable the optimization of form to dry ratio within the filtration cycle as well as the "effective submergence" of the drum when the slurry level in the tank is at the maximum
The majority of drum filters have a valve with three bridge blocks and a single row pipe plate as shown below and on the right
The duty of the bridges is: Vacuum and blow zones separating bridge. This bridge cuts off the vacuum so it is slightly wider than the internal pipe port
Dead zone bridge: This bridge opens to vacuum once a compartment submerges
Start-up assist bridge: At start-up, the upper vacuum zone is open to atmosphere and a cake may be formed only when closing the valve that controls this zone
Once the cake starts to emerge from the tank the valve is gradually opened and fully opened when the entire drum face is wrapped in the cake
Since in continuous operation both lower and upper zones are under vacuum this bridge is slightly narrower than the internal pipe port so that the vacuum is continuous and the cake is held onto the drum
The drum deck is divided into separately isolated compartments each subjected to vacuum or blow while the drum is in rotation
The timing of vacuum or blow depends on the bridge set of the main valve
The compartments are divided with grooved division strips along the drum face and around the circumference of the drum head
These division strips are holding synthetic grids shown on the right that covers the entire drum and serve to support the filter cloth
The filter cloth itself is fastened to the drum face by inserting special caulking ropes into the grooves
The filter cloth retains the cake and is fastened to the drum face by inserting special caulking ropes into the grooved division strips
Nowadays, with some exceptions, they are made from synthetic materials such as polypropylene or polyester with monofilament or multifilament yarns and with sophisticated weaves and layers
The image on the right shows the method of joining the cloth ends with clippers and to retain the fines from passing through to the filtrate multifilament strings are threaded across the entire cloth width
Another option quite often used on belt discharge filters is to join the ends with a special sewing machine
Innovation is our forte and we strive to design and develop a precision engineered range of Activated Carbon Filters. All these filters are designed in order to remove color, odor and bad taste from the water. These filters treat activated carbon with oxygen traps the particles and adsorb other impurities from the flowing stream of water. The offered range of carbon filters is highly effective in removing chlorine, sediment, and volatile organic compounds (VOCs). To attract the impurities, the vast area of activated charcoal gives these filters countless bonding sites. We also offer these filters in custom-built range and at market leading prices.
As compared to other continuous filtration processes, Horizontal Leaf Filter offers the simplicity of the process, easy operation, and maintenance, modest space requirement low energy consumption and low capital outlay.
Apart from bag filters other equipment such as cyclones, venturi, scrubbers, electrostatic precipitates etc. can be used for the recovery of particulate matter. However, out of all these equipment bag filters becomes the best choice under the following circumstances:
The final product is very expensive and as a result, high collection efficiency is required.
With our expertise in this domain, we are offering our valued customers with a wide range of Sand Filter. These products are widely used in homes, distilleries and food and beverage industries as they are best known for their quality filtration and superior quality water. We offer all our filters at unmatched market prices so that our customer will be maximum benifited.
