Background technology

Along with the great attention of country to environmental protection, the regional trade effluent of China, the scheme of centralized treatment of urban sewage is progressively implemented, and big-and-middle-sized sewage treatment plant in all parts of the country builds just energetically and comes into operation successively.And how to make good use of the facility of these constructions fully, the efficient low-consume high-quality handle a large amount of sewage well, benefit the society and the people, just the particularly important problem that faces of our sewage treatment industry.Because it is abundant to flow in the various sewage of sewage treatment plant impurity content, particularly in the trade effluent contained sewage various rubbish such as sandstone, fiber, cloth hair, gummed paper, its shape such as adhesive tape differs; Not of uniform size; Carry out the early stage of sewage and filter, catch all in one draft the various impurity that are rich in the sewage as much as possible, the minimizing dosage of subsequent treatment; Increase the dilatation of sewage disposal, guarantee that quality of sewage disposal has great significance.Very fast in China's paper industry development simultaneously; Spread all over the place in the rivers and lakes in the whole nation; A lot of irregular paper mills every days is when gulping down into great amount of water resources; Discharge the plain boiled water that is rich in paper pulp be equal to again, both polluted human water resource of depending on for existence, in vain loss the has been arranged valuable resources of production.So we need a kind of existing very big filter ability badly, have the machine of fine filtering ability to help the recycle that paper industry is accomplished energy-saving and emission-reduction and industrial water again.

At present the wastewater treatment in China industry is used blocks dirty barrier, is mostly the fence form, with planar grid plate plug-in type, to change the hub grid board-like and the crawler belt screen is circulating in the majority.The plane screen is plug-type to be that several screens use in turn, or inserts irrigation canals and ditches and block dirt, or slings artificial scarfing cinder; Changeing hub screen formula is to arrange that on the commentaries on classics hub of circle rectangular Turbogrid plates, sewage flow into commentaries on classics hub inside, flow out after barrier filters; Disclosed a kind of water treatment facilities in circulating crawler belt screen such as the Chinese patent numbers 200420022743.0; It mainly comprises support, is provided with crawler type grid net in the said support, and the grid net is done at the bottom of the irrigation canals and ditches up circular flow and reached and block dirty purpose; Both sides ride on the roller in groups, roller has chain drive; The grid net is formed by connecting straight plate washer and grizzly bar, and above-mentioned grizzly bar itself is thicker, between the gap also bigger.In sum, the common fault of blocking dirty barrier of sewage treatment industry use at present is exactly for the impact of resisting current and guarantees effective filtration area, and the barrier bar must be sturdy; And sparse, mostly its grid hole is prolate shape, is of a size of several millimeters to hundreds of millimeters; Therefore can only stop some gummed papers, adhesive tape, float stone, cloth waste, and for accounting for various more tiny fibers most in the sewage, the filtration of impurity etc. but is like water off a duck's back; And often overworked strip, block rubbish; Seal mesh, be difficult to cleaning, so its effect performs practically no function.Cause the flow burden of sewage disposal to increase, dosage increases, and the capacity of final sewage disposal reduces.

Chinese patent ZL200720005184.X is disclosed a kind of many with crawler belt sewage water filtration machine, is predecessor of the present invention, is a kind of small-sized, better simply filter; It mainly includes the convex cabinet of inclination 45 degree of intake-outlet, and oblique cutting is gone into the frame of cabinet, and frame is provided with driven roller; Jockey pulley, regulating roller, bottom roller and upper and lower supporter rack; Annular grid filter screen is coated on driven roller and the bottom roller, makes shuttling movement from the bottom to top, and sewage flows into from the pop-up rack; The current that filtered flow away from off the net, and filter residue is gone to off line by guipure to driven roller, are removed down by scummer.The upper and lower supporter rack is the grid that is welded into band steel, slides in the above in order to the support filter screen, and the filter screen limit that rubber is pushed down operation is equipped with in the cabinet both sides, in order to isolating filtering area and filtering area, regulating roller with visit the limit switch and cooperate in order to adjusting filter screen sideslip.Above-mentioned filter can filter out big small impurities from sewage, filter screen can not hung slag yet, and it is also easy to clean; But exist some problems: one be 45 the degree the screen pack angle excessive; When in big flow, polymictic environment, working,, can produce the impurity layer snowball effect that rolling increases of rolling downwards because it is thicker attached to the impurity layer on the 45 degree wire sides to filter the back; The intersection that the impurity of rolling is kept afloat with filter screen rolls, and has influenced on filter effect and the filter residue and has sent; The 2nd, the upper and lower supporter rack of this machine is because band steel is skewed grid; And the frame of pop-up rack is that angle steel is made, so overall construction intensity is not enough, at big flow, many impurity; Water depth pressure is big, when water flow impact pressure is big; Bulk deformation rocks, and causes structure crack, scratches filter screen and isolated failure; The 3rd because upper and lower supporter rack and filter screen are direct sliding friction, when filter screen bears bigger hydraulic pressure and impulsive force, cause frictional force increase several times, consequently the stressed increase of machine and skid, filter screen and holder net bar ground away very soon; The 4th, fix owing to isolate offset plate, directly compress the filter screen of operation, add the effect of water pressure, filter screen and offset plate are also ground away soon; The 5th, regulating roller is arranged on the rear of jockey pulley; Because filter screen is in a steering angle and arrive vertical jockey pulley again on regulating roller, so work as filter screen sideslip (looking down the plane of frame) to the inside, regulating roller is controlled when traversing left (see push-and-pull in this patent specification accompanying drawing 1 adjusting deviation device 7 traverse regulating roller); Should make the outer side shifting correction of filter screen to frame; But when regulating roller is moved to the left, be coated on the regulating roller that inboard filter screen moves to left along with regulating roller and tensile force fluffs, cause filter screen skew to the inside again; So two kinds of physical force make the direction of filter screen skew conflicting, do not reach the effect of filter screen tuningout.
