Abstract

The utility model discloses a new waste sieving device which is essentially added and arranged with an inner sieving cylinder on the original waste saving rotating-drum sieving device. The hole of the screen stencil of the inner cylinder is larger than that of the outer sieving cylinder. The utility model comprises a motor, a convey belt, a convey belt carrier roller, a sieving body, an inner sieving cylinder, an outer sieving cylinder, a sieving cylinder support ring, a drive gear wheel and a sieving cylinder gear wheel. The utility model is characterized in that the motor drives the gear wheel drive to rotate, while the drive gear wheel meshes with the transmission sieving cylinder gear wheel which drives the outer sieving cylinder and the inner cylinder. Trashes enter from the sieving cylinder inlet, and after being sieved by the sieving cylinder, trashes with the bigger sizes are discharged from the outlet of the inner sieving cylinder into the furnace for processing, while trashes, mud and sands with the smaller sizes than that of the sieving net holes fall on the convey belt and are sent to be processed. The sieving body of the sieving cylinder is arranged non-sequent or horizontally on the sieving rack. The utility model has the advantages of simple structure, easy manufacturing, convenient installment and application, low manufacturing cost, simple operation, clean sieving or wastes and can be applied in trash sieving devices.

Description

Novel screening rubbish device

Technical field

The utility model belongs to refuse disposal installation, particularly a kind of novel screening rubbish device.

Background technology

Mostly existing garbage disposal is with vibratory sieve, plansifter, drum sieve screening thick rubbish such as paper, polybag, packing box, wooden root and so on to be selected, send incinerator to burn, slightly little sand, stone, mud and so on refuse difficult to burn then goes out from the sieve end, be directly used in compost or the plant that cultivates apple trees, also have directly garbage loading embeading handled, these equipment are not thorough because of screening, and stifled easily fire is unfavorable to burning in burning process.

Summary of the invention

The purpose of this utility model provides a kind of screen drum inner core at the rotary screening rubbish of original single sieve rotating cylinder device to be increased and a rotating cylinder screen drum is installed as interior screen drum, and interior screen drum is connected with outer screen drum and by being welded to connect fixing with the division post bar.Interior screen drum inner tube wall is evenly equipped with loose tooth.Screening rubbish device is removed nonflammable thing mud, sandstone, work a little completely, is beneficial to waste incineration, and simple in structure, cost is low, acts on greatly, is beneficial to sanitary, easy to manufacture, easy to install novelty and screens the rubbish device.Comprise motor, belt conveyor, belt pulley, cylinder thrust bearing, thrust basin, garbage inlet, garbage outlet, belt idler, sieve body, screen frame (unit), rubbish gateway end screen drum support ring.Screen frame (unit) is equipped with sieve body, outer screen drum, interior screen drum.Motor, belt idler, roller bearing, driving gear are installed.In the outer screen drum inner core interior screen drum is arranged, interior screen drum is to there being the division post bar to separate between the outer screen drum, and interior screen drum inner tube wall has loose tooth, there is the screen drum support ring at outer screen drum two ends, outer screen drum has the screen drum gear, screen drum gear and driving gear engagement, and driving gear is connected transmission with shaft of motor.

Interior screen drum, outer screen drum, the oblique screen frame (unit) that is installed in of sieve body, also the screen cloth that can become horizontal direction to be installed in screen frame (unit), outer screen drum and interior screen drum has mesh, outer screen drum is more smaller than the screen cloth mesh of interior screen drum, one interval is arranged between sieve body and the outer screen drum, be connected with the division post bar between interior screen drum and the outer screen drum and be welded to each other and be connected and fixed.The screen drum gear is fixed in an end of outer screen drum, and the screen drum inner tube wall was uniform in loose tooth was fixed in, and lays by spirality and installs.Axially have the thin slightly rubbish silt stone outlet of discharge along screen drum at the bottom of the sieve body, outlet is horn mouth.

The utility model has the advantages that increases an interior screen drum in original screen drum inner core, it is cleaner to become two screen drum screening rubbish, is more conducive to burning disposal rubbish.Simple in structure, easy to manufacture, easy to install, cost is low, can use on drum-type screening rubbish device.
