Embodiment Construction
[0012] refer to figure 1 , a drying diaphragm plate and frame filter press system, comprising a diaphragm plate and frame filter press 10, a conveyor belt 20 for receiving materials is arranged below the discharge port 11 of the diaphragm plate and frame filter press 10 for discharging materials, the A box body 30 is arranged on the transmission direction of the conveyor belt 20, and the two ends of the box body 30 are provided with openings for the conveyor belt 20 to enter and exit the box body 30, and the diaphragm plate frame filter press 10 passes through the compressed gas discharge pipe. 12 is connected to an air compressor (not shown in the figure), through which the compressed air discharged from the diaphragm plate and frame filter press 10 can be compressed and recovered again to avoid the compressed air discharged from the diaphragm plate and frame filter press 10 It is directly discharged into the external environment. The air compressor is connected with a heatin...

The invention discloses a drying diaphragm plate-frame pressure filtration system which comprises a diaphragm plate-frame filter press, wherein a conveyor belt is arranged under a discharging port of the diaphragm plate-frame filter press; a box is arranged along a conveying direction of the conveyor belt; the diaphragm plate-frame filter press is connected with an air compressor through a compressed air discharging pipe; a heating device is connected with the air compressor; an air feeding pipe is connected with the heating device; the other end of the air feeding pipe is connected with one end of the box. According to the invention, the heating device is used for heating the compressed air after being press-filtered by the diaphragm plate-frame filter press, and then the air feeding pipe is used for feeding the heated compressed air into the box for drying the materials, so that the heat energy loss of air caused by directly emitting the compressed air can be avoided, the moisture content of the materials can be further reduced and the social energy resource can be saved.
Description
technical field [0001] The invention relates to the field of filter press, in particular to a plate and frame filter press system with a drying function. Background technique [0002] Filter press is a kind of equipment that separates materials from solid and liquid through pressure filtration. It is widely used in food, chemical, environmental protection and sewage treatment industries, especially for the separation of sticky and fine matter. It has unique advantages. For example, the sludge produced by chemical and domestic sewage treatment has a water content of 95% -99%, and must be dehydrated to reduce its volume before it can be discharged. After dehydration treatment, the moisture content is reduced to below 60% before it can be landfilled or incinerated. [0003] Existing filter presses on the market deal with sludge with a moisture content of 60%-85%, and existing diaphragm plate-and-frame filter presses cannot further reduce the sludge moisture content to 50%-60%;...
