Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] In the present invention, the orientation words used such as "up, down, left, and right" usually refer to the up, down, left, and right shown in the accompanying drawings; inside and outside.

[0028] Such as figure 1 , figure 2 As shown, the press filter plate used in the electroosmotic sludge high-dry dehydration equipment of the present invention mainly includes a fixed plate frame 1, an anode plate 2, a movable platen 3, a cathode conductive net 106, a tympanic membrane 5 and a sludge guide cylinder 6. The cathode conductive net 104 is installed on the movable platen 3 , the anode plate 2 is installed on the fixed plate frame 1 , and the tympanic membrane 5 is installed between the fixed plate frame 1 pre-pressed and the movable platen 3 .

[0029] Such as figure 1 , figure 2 As shown, there are raised steps on the peripheral edge of the fixed plate f...

Abstract

The invention provides a pressing filter plate for electroosmotic sludge high-dryness dewatering equipment. The pressing filter plate comprises a filter plate frame, filter cloth, a filter disc and sludge conveying concentric holes, wherein the front surface of the filter plate frame unidirectionally sinks to form a pressing filter chamber; the filter disc is arranged at the bottom of the pressing filter chamber; the filter cloth is arranged on the filter disc; a cathode conductive filter screen connected with a cathode copper row is arranged between the filter disc and the filter cloth; an anode plate is arranged at the back of the plate frame; a cavity into which liquid or gas can be charged is formed between the filter disc and the plate frame; a push plate device is further arranged between the cavity and the filter disc; the cavity consists of a drum membrane, an inner steel base plate and an outer steel base plate; and the drum membrane is arranged on the inner peripheries of the steel base plates. By charging water to pressurize the cavity, a sludge pressing pressure is increased; meanwhile, through the push plate device, the uniformity of a pressing force is ensured and whole-process pressing is achieved; therefore, the moisture content of the sludge is further reduced.

Description

technical field [0001] The invention relates to the field of sludge disposal equipment components, in particular to a filter chamber mechanism in sludge electroosmosis high-dry dehydration equipment. Background technique [0002] On the market, plate and frame diaphragm filter press is mostly used for deep sludge dewatering equipment. Due to the need to add lime, iron salts and other chemicals for dehydration of the plate and frame diaphragm filter press sludge, it is difficult for the treated sludge to meet the national pollution control standards. After the sludge is treated, the moisture content is less than 50% before it can be sent to the domestic waste landfill. Buried for disposal. Moreover, additives to sludge reduce the calorific value of sludge as fuel, which is not conducive to the disposal and utilization of sludge in the later stage. [0003] Existing equipment The filter chamber mechanism in the high-dry sludge dewatering equipment presses, relying on the oil...
