The filter press uses a special filter medium

        The filter press adopts a special filter medium, and its surface is embedded in alloy steel castings. The filter press manufacturer and the parent and child parts form a variable filter chamber. When the sludge enters the filter chamber from the center to a certain amount, the hydraulic pressure only provides pressure. The pressure plate acts on the sludge in the filter chamber to achieve the purpose of deep dewatering of the sludge.

What is the feed pressure of the ultra-high pressure sludge dryer? After the sludge is adjusted, the high-pressure pump sends the material into the filter chamber. The feed pressure between the filter press and the belt filter press is 1.2-2 MPa, of course There is also an ultra-high pressure sludge filter printing machine. An opportunity is installed between the feed pump outlet and the filter press inlet to monitor the feed pressure to control the feed rate and return to the valve.

The so-called feed pressure is usually called the feed pump pressure when the filter press is running. Different filter cloths and sludge concentrations require different feed pressures. When the sludge moisture content is high, the sludge concentration is very low. At this time, a lot of pressure is required, and the sludge is dehydrated into cakes through high-pressure filtration, which also shortens the feeding time, but increases the strength of the filter cloth.

In recent years, with the continuous development of the economic construction of small filter presses, many cities have had to restrict hydroelectric power generation. For the water supply pumping station, most of the existing equipment is outdated, and the process and power supply equipment are outdated. The filter press sends the input filtrate to the filter.
Under the action of the shunt pipe, the filter is divided into plate type and frame type filter plate, which is composed of two filter cloth bags and filter cloth. At this time, the filter cloth is used to contact the filter press. The filter cake can be used for liquids to pass through the filter cloth. The box filter presses the liquid filter on both sides of the plate frame under the action of interception, guidance and convergence, and the filtered liquid is discharged from the plate filter press device.

A small filter press guides the filtered liquid into two solid filter plates, and uses the space in the middle concave space to achieve the filtering and separation function. The water outlet under each filter plate passes through a box-type filter press. The pipe discharges the filtered liquid. Frame filter press.

The filter press produced will be widely used in municipal sludge. In environmental protection industries such as printing and dyeing sludge, electroplating sludge, coal sludge, chemical sludge, river dredging, etc., filter press is a kind of chemical dewatering machinery. Although the filter press generally runs intermittently, it has a large basic investment and low filtration capacity, but it has a large filter driving force, a high solid content in the filter cake, a clear filtrate, a high solid recovery rate, and an adjustable drug. Some small sewage treatment plants still widely adopt advantages such as low energy consumption.
