Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Such as figure 1 As shown, the belt filter press of the present invention includes an upper rotary crawler 1, a lower rotary crawler 2, and a pressure roller 3 rotatably arranged inside the upper rotary crawler. The outer wall of the pressure roller is provided with a plurality of The pressure blocks 4 extending radially and evenly spaced can contact the inner surface of the upper revolving track when the pressure roller 3 is driven to rotate and produce a pressing effect. The upper rotary track and the lower rotary track are arranged at intervals up and down, the upper rotary filter belt rotates counterclockwise under the drive of the upper rotary wheel 5, and the lower rotar...

Abstract

The invention discloses a belt filter press which comprises an upper slewing crawler belt, a lower slewing crawler belt and a press roll which is rotatably arranged inside the upper slewing crawler belt or the lower slewing crawler belt. Outer wall surface of the press roll is provided with multiple briquettes which extend radially along the press roll and are evenly spaced. When the press roll is driven to rotate, the briquettes can be contacted with the medial surface of the upper slewing crawler belt or the lower slewing crawler belt to produce an extruding effect. According to the belt sludge filter press, the two crawler belts are utilized to extrude sludge to be dehydrated, and the high-speed rotary briquettes of the press roll are alternately contacted with the upper slewing crawler belt so as to intermittently inject sludge into a front channel. As outside of the two crawler belts is sealed, moisture in the sludge is forced to pass through the crawler belts to be discharged, thus effectively raisin dehydration effect of the sludge. On-site low-noise treatment of sludge is realized, and sludge transport and reuse water problems are greatly alleviated.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a belt filter press. Background technique [0002] A large amount of silt will also be produced in urban construction, and it faces many problems such as noise, energy consumption, and transportation in silt treatment. At present, the silt drying technology at home and abroad mainly adopts chemical solidification method or dehydration drying method. The processing object of the chemical solidification method is mainly fluid sludge with high moisture content, which needs to add a large amount of curing agent and weighting agent, which is difficult and costly in actual use. The dehydration and drying method mainly uses mechanical dehydration to achieve solid-liquid separation. At present, a single solid-liquid separation equipment is often used, such as vacuum filter, plate and frame filter press, belt filter press or horizontal centrifuge for solid-liqui...
