Description
Technical field
The utility model relates to the filter press in a kind of dehydration equipment field, particularly relates to a kind of many tensionings belt filter press.
Background technology
In the industrial and agricultural productions such as metallurgy, chemical industry, papermaking, process hides, alcohol sewage disposal, livestock culture, usually need to carry out waste residue, waste material dehydration, belt filter press is owing to have and can uninterruptedly produce continuously, simple to operate, operation expense is low, dewatering efficiency comparison high and being used widely.Existing belt filter press has been a kind of device product of comparative maturity through for many years development, but on the whole, the moisture of filter cake is still higher after its dehydration, the requirement that does not also reach subsequent treatment.
The belt filter press dehydration is exactly by strainer double team material, thereby material is squeezed at pressure roll to be leached wherein water partial pressure come, the moisture of filter cake height is by material suffered pressure size and Time dependent that is squeezed on pressure roll after the press filtration, suffered pressure is larger, extrusion time is longer, and the filter cake moisture content after the press filtration is just lower.The extruding force of pressure roll derives from the idler roller of belt filter press.Existing belt filter press generally has two tight rollers, and one is upper strainer idler roller, and by strainer in its tensioning, one is the lower filter belt idler roller, by its tensioning lower filter belt.So, as long as improve constantly in theory the tensile force of strainer idler roller and lower filter belt idler roller on the belt filter press, improve the pressure that material is subject at pressure roll, constantly increase the quantity of pressure roll, increase material in the time that pressure roll is squeezed, just can constantly reduce the moisture of filter cake after the material press filtration.
But facts have proved really not soly, at first, the tensile force of idler roller can not unlimited increase, and strainer has the limiting value of its pulling force that can bear, and tensile force is too large, also can cause the high-moisture material to run material; Secondly, the extruding force on each pressure roll can't equal the tensile force on the idler roller, because can produce friction loss etc., the pressure roll quantity in the pressure roll group is more, and the pressure loss is larger; The 3rd, because idler roller tensile force total amount is constant, the pressure roll quantity in the pressure group is more, and the pressure loss is more, extruding force on the pressure roll and the difference of the tensile force on the idler roller are just larger, therefore increase the further reduction that pressure roll quantity also can't realize filter cake moisture.
Therefore, address the above problem, the water content of material filter cake after the further reduction press filtration, wherein an important approach is exactly: in the scope that the belt filter press strainer can bear, and the high-moisture material do not run in the situation of material, suitably increases the tensile force of idler roller, takes simultaneously compensation mechanism, the pressure that loses on each pressure roll in the pressure roll group is compensated, it is consistent with the tensile force of idler roller as far as possible.In addition, can also be on the basis that keeps each pressure roll pressure not lose, by increasing pressure roll quantity, to reach the time that material is extruded that increases.Yet existing belt filter press can't resolve the problems referred to above.Therefore, need to innovate on the basis of existing belt filter press, a kind of technical scheme that can realize the compensation of the pressure roll pressure loss is provided.
In addition, the upper strainer rinse water pipe of existing belt filter press is installed in the top of strainer, sprays water from top to bottom strainer is cleaned, namely be that working face from upper strainer cleans, it is clear to form recoil, and cleaning performance is bad, has also affected to a certain extent the raising of equipment dewatering efficiency.The installation kit jacket degree of upper strainer regulating roller and lower filter belt regulating roller and upper strainer and lower filter belt is too little, and the strainer tuningout is insensitive, the easy sideslip of strainer.And because of the installation double team degree of upper strainer and lower filter belt too little, do not become the local larger gradient, cleaning when water pipe cleans strainer in time to make rinse water separate with strainer, can make rinse water cross and be about to along strainer inflow press filtration and also affect the dehydrating effect of equipment in the material of press filtration.More than these all need to innovate and are overcome and solve.
Because the defective that above-mentioned existing belt filter press exists, the inventor is based on being engaged in for many years abundant practical experience and professional knowledge of this type of product design manufacturing, and the utilization of cooperation principle, positive research and innovation in addition, in the hope of founding a kind of many tensionings belt filter press of new structure, can improve general existing belt filter press, make it have more practicality.Through constantly research, design, and after repeatedly studying sample and improvement, finally create the utility model that has practical value.
