Embodiment 1

[0030] Example 1 as Figure 1-7 As shown, a kind of electroosmotic belt press sludge dewatering equipment is a daily treatment of 50 tons of 80% sludge sludge dewatering device, including a top frame 15, a base 16 and two dewatering units, and two A dehydration unit, wherein the dehydration unit includes frame 1, upper press belt 2, lower press belt 3, guide rail 4, transmission shaft 6, single-sided toothed synchronous belt 7, driving structure 8, tensioning device 9, filter belt 10, DC The power supply 11, the support wheel 12, the cooling and dehumidification isolation air duct 13 and the sludge discharge water channel 14 are inserted into the guide rail 4 in the installation groove of the frame 1, and the frame 1, the top frame 15, and the base 16 are all resin, Fiber-reinforced or clad metal-reinforced composite materials, frame 1 is a multi-layer module of horizontal long composite material structure, which is convenient for capacity expansion and maintenance. The guide...

Embodiment 2

[0035] This embodiment is an electro-osmosis belt press sludge dewatering equipment for daily treatment of 75 tons of 80% sludge. Its structural parameters: length and width are exactly the same as those in Example 1, and only one dehydration unit is added to the height.

Abstract

The invention discloses an electroosmotic belt press sludge dehydration equipment, which comprises a top frame, a base and two dehydration units. Toothed synchronous belt, double-sided toothed synchronous belt, tensioning device, filter belt, supporting wheel, air duct, water channel and power supply, powered by double-sided toothed synchronous belt, and the frame is surrounded by an upper press belt and a lower press belt moving around Belt, a plurality of single-sided synchronous belts arranged alternately as a link, upper or lower bridge plates arranged in a horizontal order according to the width of the upper bridge plate or lower bridge plate to form a crawler structure, the upper press belt and the lower press belt respectively Connected to the positive and negative poles of the DC power supply, the upper press belt and the lower press belt clamp the filter belt and enter the dehydration area of ​​the rack to promote the flow of water molecules in the sludge to the lower bridge plate with negative potential. The efficiency of pressing and dehydration is greatly improved, the sludge volume is significantly reduced, and the high-dryness sludge cake produced is conducive to the later utilization of resources.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and relates to a mechanical equipment for sludge dewatering, in particular to an electroosmotic belt press sludge dewatering equipment. Background technique [0002] The by-product of treating industrial sewage and urban domestic sewage is viscous sludge, because this kind of sludge has high water content, is not easy to accumulate, is difficult to store and transport in a centralized manner, and is not convenient for later resource utilization. In order to meet the government's requirements on sludge reduction, recycling, and harmless treatment, physical dehydration is usually used in projects to obtain sludge cakes with a certain dryness. At present, the most widely used dewatering equipment in engineering is the belt press dehydrator. This type of equipment relies on the double-layer press belts that move synchronously and is wound repeatedly to squeeze the wet sludg...
