Abstract

The invention is widely applicable to the technical field of dehydration of paper mill sludge, electroplating sludge, leather sludge, domestic sludge and various types of sludge and particularly relates to a spiral filtration dehydrator. The spiral filtration dehydrator comprises a rack, wherein two spiral shafts are arranged on the rack in parallel, one end of each spiral shaft is connected with a spindle driving device, the two spiral shafts are respectively installed in two filter cartridges, towing wheel shafts are arranged between the outer side walls of the two filter cartridges and the two filter cartridges, one end of each towing wheel shaft is connected with a driving device, two ends of each filter cartridge are respectively a feeding port and a discharging port, the rack is provided with blanking port corresponding to the discharging ports, filtrate outlets are respectively formed in the middle positions, corresponding to the filter cartridges, on the rack, bristle brush roller devices are respectively arranged above the two filter cartridges, and a flushing water device is arranged on one side of the bristle brush roller devices. The spiral filtration dehydrator can decrease flocculant usage amount, adjust spiral and the roller rotation speed according to feeding concentration and control the staying and dehydration time of the sludge in a device. A dehydration effect is good, and material requirements are low. The outlet sludge concentration is adjustable, automatic operation is achieved, and labor intensity is low.

Description

technical field

[0001] The invention relates to a spiral filter dehydrator, which is widely applicable to various types of sludge pre-dehydration technologies such as papermaking sludge, chemical sludge, printing and dyeing sludge, heavy oil sludge, electroplating sludge, leather sludge, and domestic sludge. field. Background technique

[0002] The spiral filter dehydrator uses a porous filter medium sieve drum to intercept the solid particles in the mixture of liquid and solid particles, so as to achieve the purpose of solid-liquid separation. It can remove a large amount of free water from low-concentration sludge, further increase the sludge concentration, and reduce the dehydration pressure of the subsequent dehydration section. The existing spiral filter dehydrator uses a large amount of flocculant, the dehydration effect is poor, and the requirements for incoming materials are high. Contents of the invention
