Abstract
The utility model discloses a curing refuse series cylinder screen, comprising a thick screen cylinder and a thin screen cylinder which are connected in series into integration. The screen cylinder is arranged on a screen frame in a rotatable way in the state of inclination, wherein, the position of the thin screen cylinder part is higher than the thick screen cylinder part. The curing refuse is sent in by the open end of the thin screen cylinder; the fine materials of the 55% of the total amount are screened out by the thin screen cylinder, and the diameters of the fine materials are less than 10 millimeters; the remainder parts are screened into about 30% fine materials whose diameters are 10-40 millimeters and the coarse materials whose diameters are more than 40 millimeters. Accordingly, the users can screen out the 55% of the fine materials only needing the thin screen cylinder at one time through adopting the cylinder screen of the utility model, and therefore, the effect of energy saving is very obvious.
Description
The utility model relates to sieving garbage equipment, particularly a kind of garbage curing serial connection rotary screen.
At present, a kind of treatment of urban garbage process commonly used is, at first the crude waste fermentation made it slaking, and then garbage curing is sieved into carse, medium and small three kinds of particulate material, handles in order to later process, and existing screening plant has two types substantially.First type comprises the coarse fodder rotary screen, belt conveyor and fines rotary screen, it is middle fines below 40 millimeters that garbage curing earlier sifts out about diameter more than 80% through the coarse fodder rotary screen, and then middle fines is delivered to the fines rotary screen by belt conveyor, sift out about 55% left and right sides diameter less than 10 millimeters fines, this type screening plant exists equipment to disperse, floor space is big, shortcomings such as energy consumption height, especially in screening process, account for the fines of garbage curing more than 55% and stood twice screening in front and back, like this, rotary screen must have bigger capacity and power, is unfavorable for very much energy savings.Second type screening plant such as Chinese patent CN87207485 put down in writing, this equipment comprises the pair of lamina rotary screen, nexine is the scalping tube, skin is the dusting cover tube, garbage curing at first passes through the scalping tube, with about diameter more than 80% is that middle fines below 40 millimeters is sieved into the dusting cover tube, and the dusting cover tube sifts out about 55% diameter approximately less than 10 millimeters fines.Second type rotary screen is than the first kinds of structures compactness, and owing to omitted a middle fines belt conveyor, energy consumption also decreases, but, because second type equipment will account for the fines front and back of garbage curing total amount about 55% and sieve twice, require rotary screen that bigger capacity and power are arranged equally, thereby still be unfavorable for energy savings.
The purpose of this utility model provides a kind of compact conformation, energy-efficient garbage curing serial connection rotary screen.
Technical solution of the present utility model is:
A kind of garbage curing serial connection rotary screen, comprise: be skewed cylindrical scalping tube and the dusting cover tube that is rotatably installed on the frame, feed hopper, slightly, in, each discharge bucket of fines and power source, transmission mechanism, wherein, described thick, the dusting cover tube is concatenated into one mutually, the length of dusting cover tube is thick, the 50%-80% of the total length after the dusting cover tube serial connection, wherein, dusting cover tube part position is higher, and scalping tube part position is lower, described feed hopper is installed in the openend top of dusting cover tube part and dusting cover tube openend is partly stretched in the outlet of feed hopper, described coarse fodder discharge bucket is installed in the openend below of scalping tube part, and the openend of scalping tube part stretches into the import of coarse fodder discharge bucket.Material discharge bucket and fines discharge bucket are installed in the below of scalping tube part and dusting cover tube part respectively in described, and their import is aimed at all sieve apertures of downside of scalping tube part and dusting cover tube part respectively.
Adopt rotary screen of the present utility model, after garbage curing sent into rotary screen by feed hopper, at first partly sift out and account for total amount about 55% through the dusting cover tube, diameter is less than 10 millimeters fines, remaining part is partly sifted out the middle material that about 30% diameter is the 10-40 millimeter through the scalping tube again, and Sheng Xia coarse fodder draws off from the openend of scalping tube part at last.From said process as seen, rotary screen of the present utility model only need the dusting cover shaft screen once can will account for the diameter of total amount about 55% sift out less than 10 millimeters fines, equipment need not bigger capacity and power, its energy-conserving action is fairly obvious; And thick, dusting cover tube is concatenated into one, and structure is very compact, and operating efficiency also improves greatly.
Below in conjunction with accompanying drawing, describe most preferred embodiment of the present utility model in detail, further specifying other purpose of the present utility model, feature and advantage, wherein:
Fig. 1 has schematically illustrated a kind of structure of garbage curing serial connection rotary screen.
Referring to Fig. 1, a kind of garbage curing serial connection rotary screen, comprise: a cylindrical scalping tube 1, one is connected in series the cylindrical dusting cover tube 2 of all-in-one-piece with scalping tube 1, the length of dusting cover tube 2 is the 50%-80% of the total length after thick, the dusting cover tube serial connection, and thick, dusting cover tube after the serial connection are skewed and are rotatably installed on the frame 3, its inclination alpha is 6 °, wherein, dusting cover tube part 2 positions are higher, and scalping tube part 1 position is lower.One feed hopper 4 is installed in openend 201 tops of dusting cover tube part 2, and the openend 201 of dusting cover tube part 2 is stretched in its outlet, so that by feed hopper 4 garbage curing is sent in the rotary screen.One coarse fodder discharge bucket 5 is installed in the below of the openend 101 of scalping tube part 1, and the openend 101 of scalping tube part stretches into the import of coarse fodder discharge bucket 5, so that the surplus coarse fodder of sieve can be sent into hopper 5 by openend 101.A material discharge bucket 6 and a fines discharge bucket 7 are installed in the below of scalping tube part 1 and dusting cover tube part 2 respectively in one, and their opening is aimed at all sieve apertures of downside of scalping tube part 1 and dusting cover tube part 2 respectively, is used for collecting respectively the material and the fines that sift out.Slightly, the dusting cover tube is connected with power source through transmission mechanism, its traditional approach can be the known mode of those skilled in that art, for example gear drive or frictional drive etc. do not repeat them here.
In order to prevent in screening process, rubbish stops up the sieve aperture of screen drum, can in above-mentioned thick, dusting cover tube, rotatably install a cylindrical clear hole brush 8, one side of its cylindrical brush hair side and the inner surface of thick, dusting cover tube 1,2 is inscribe mutually, the axle of this clear hole brush 8 is connected with power source by clear hole brush transmission mechanism, and be mounted to when rotary screen is worked, clear hole brush 8 turn to slightly, dusting cover tube 1,2 turn to identical.Its kind of drive also can be the known mode of those skilled in the art, and for example chain transmission etc. does not repeat them here.
Above-mentioned clear hole brush 8, when rotary screen is worked, hole clearly, can brush wall again, when rubbish has surperficial moisture content, before forming sticking hole as yet, just it can not destroyed, therefore clear hole effect is fine, msw water content less than 30% situation under, rotary screen can normally be worked continuously.
According to design of the present utility model, within the scope of the claims, those skilled in the art also can do some conspicuous changes to the foregoing description, or designs the embodiment of other similar structures.
