Abstract
The present invention discloses a powerful cabinet type press filter, which comprises a frame portion, a filtration portion and a filtration plate pressing device, wherein the frame portion comprises a bracket, two parallel cross beams on the bracket, a thrust plate erected on the cross beam and a pressing plate erected on the cross beam, the filtration portion comprises a plurality of filtration plates aligned between the thrust plate and the pressing plate, filtration plates are adjacent to each other so as to form the filtration chamber, the center and the edge corner of the filtration plate are provided with through holes, the through holes in the centers form a liquid inlet channel after assembly, the liquid inlet channel is communicated with a water pump, the through hole on the edge corner is communicated with the liquid outlet on the filtration plate bottom corner, the filtration plate pressing device is positioned on one end of the cross beam and is movably connected with the pressing plate, one side of the filtration plate is provided with a compressed air inlet, and a gas inlet pipeline is communicated with an air compressor. According to the present invention, the water content of the filter residue obtained through pressure filtration is low, the filter residue is dry and hard, and the weight is reduced by about 3/5, such that the waste residue treatment cost of the enterprise is substantially reduced; and most of the filter residue components are fiber particles, such that the waste can be changed into treasure, and can be used as the fuel during the production process of the enterprise.
Description
Technical field
The present invention relates to treatment of dyeing wastewater apparatus field, be specifically related to a kind of powerful chamber-type press filter.
Background technology
A large amount of dyeing waste water can be produced in printing and dyeing enterprise production process, wherein containing a certain amount of fiber grain, process respectively again after needing solid-liquid pressure-filtering to be separated.Chamber-type press filter is mainly used in the slurries Separation of Solid and Liquid process of sewage sludge, under the pressure effect of dehvery pump, by needing the feed liquid of filtering to send each filter chamber to, on filter cloth, form filter residue by filter medium, until be full of filter chamber formed filter cake, then by filter cake from removal filter screen.In actual production process, filter pressure is generally provided by pan feeding pump, so affect the feeding pressure that the very important factor of the rate of filtration is exactly pan feeding pump, find in actual use, in filter-press dehydration process, reduced the porosity of filter cake by hydrostatic pressure, most of moisture can be discharged, but only by improving hydrostatic pressure, dehydrating effect is unsatisfactory, and the waste residue moisture content after process is too high.The mode of printing and dyeing enterprise process filter residue is generally that defrayment processes to filter residue special disposal enterprise by weight, and the producing cost therefore born at this one-phase is very considerable.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of powerful chamber-type press filter, and the filter residue water content be press-filtered out is low, and filter residue is dry and hard, weight saving about 3/5, greatly reduces enterprise's Solid state fermentation cost; And filter residue composition mostly is fiber grain, can turn waste into wealth, the fuel as enterprise production process uses.
The present invention is achieved through the following technical solutions:
A kind of powerful chamber-type press filter, comprises rack section, filtration fraction and filtering board pressing device, and described rack section comprises twice parallel beams on support, support and the thrust plate be erected on crossbeam and pressure strip; Described filtration fraction is made up of multiple filter plate be arranged between thrust plate and pressure strip, filter plate is adjacent composition filter chamber between two, and filter plate center and corner are provided with through hole, and assembling rear center through hole forms feed pathway, feed pathway is communicated with water pump, and corner through hole is communicated with the liquid outlet at filter plate base angle; Described filtering board pressing device is positioned at crossbeam one end, and with pressure strip mobile link, described filter plate side is provided with compressed air inlet port, and air inlet duct is communicated with air compressor machine.
The further improvement project of the present invention is, described air compressor machine is communicated with a main pipeline, and multiple branch pipe(tube) that main pipeline is arranged is communicated with the air inlet on each filter plate respectively.
The present invention further improvement project is, before and after described filter plate, two sides is equipped with boss, and filter cloth covers on it.
The present invention further improvement project is, described filtering board pressing device comprises the thread spindle that is connected with pressure strip and drives with thread spindle the motor be connected.
The present invention compared with prior art, has following obvious advantage:
The present invention carries compressed air due in the filter chamber that formed to filter plate, strengthen the pressure in filter chamber, solid-liquid separation effect is significantly promoted, the filter residue of about 12 tons formed after the dyeing waste water press filtration of script 100 tons, filter residue after press filtration of the present invention only has about 5 tons, weight saving about 3/5, significantly reduces Solid state fermentation expense.And filter residue composition mostly is fiber grain, dry and hard filter residue, can research and develop and use as the fuel needed for enterprise production process, turn waste into wealth.
