Abstract

The utility model relates to a refuse treatment device which can sieve urban refuses. The refuse treatment device takes a motor and a speed reducer as a power section to drive rubber rollers mounted on a machine frame, and then an integral roller sieve cylinder comprising a frame is driven to do swivel motions. During sieving, the utility model can effectively separate large granules from small granules, and pick out light articles such as plastic and paper. The removable sieve mesh plate of the roller sieve cylinder can be changed according to different requirements, with multiple uses.

Description

Octagonal screening machine

The utility model is a kind of refuse treatment plant, relates in particular to the sifting sort technology of municipal refuse.

Screening machine before the utility model, mostly be that garden shape roller screen tube carries out sorting work, adopt overall screen web plate structure in the cylindrical shell, inconvenience is changed in repair, and expensive big, the interior nothing of cylinder prevents twining, blocking device, twines easily, stops up in the sub-sieve process, sieve not thorough, the light-weight articles in the rubbish can't go-on-go etc. shortcoming.

The utility model is in order to overcome the shortcoming of above-mentioned refuse treatment plant, to propose a kind of refuse treatment plant of new structure.

The utility model is to realize like this, the roller screen tube of the horizontal rotation of four rolling rubber tires and its support is housed on the frame plane, screen drum is made of garden, two ends shape dead turn and middle rigid frame, the polylith sieve plate is fixed on the framework, charging aperture is arranged at roller screen tube one end top, and discharging opening is arranged at other end bottom.There is an openable hood horizontal roller screen tube outside, frame two ends frame a fixedly long tube that passes in the roller screen tube, long tube is positioned at roller screen tube axis top, be furnished with a plurality of hooks on the pipe, hang many hoisting chains, an end is fixed an end and is dangled, and has one to collect mouth at roller screen tube discharge port end middle part, collect in a mouthful end and the screen drum and communicate gatherer that constitutes by negative pressure source of another termination.The axis and the horizontal plane of roller screen tube integral body have a slanted angle, and the feed inlet end position is higher than the discharge port end position, is convenient to the screening of material.

Adopt sieving garbage treatment facility provided by the utility model, decapacitation is carried out fragment of brick, sandstone etc. in the domestic waste outside the go-on-go, and can also collect light-weight articles such as paper and plastics, owing to adopted the removable sieve plate of polylith, can require to select for use the sieve plate of different size according to sieving technology, the rubber tire frictional drive is adopted in the realization of screening process, and running is steady, and noise is little.Overall structure is simple, and is easy to maintenance, for the go-on-go municipal refuse provides a kind of novel device, general dissemination arranged.

Below in conjunction with detailed the describing of structure chart of the present utility model:

Accompanying drawing 1 is a side view of the present utility model;

Accompanying drawing 2, be the utility model accompanying drawing 1 to view;

When sieving work, actuating motor (1) at first, by reductor (2), transmission of power to the rubber roll (4) that links to each other with two power transmission shafts (3), four rubber rolls are supporting horizontal roller screen tube (5), be the active rubber roll in the side that motor is housed, opposite side is two independently rubber rolls, be driven pulley, the rotation of roller screen tube is by the friction rubber roll of four supports and dead turn (6) frictional drive of roller screen tube, cylindrical shell is done uniform rotation, the roller screen tube is made of garden, two ends shape dead turn and middle rigid frame (7), on it polylith sieve plate can be installed, there are an openable hood (8), the installation of roller screen tube in roller screen tube outside, its axis and horizontal plane have a slanted angle, feed inlet end is higher than discharge port end, and whole parts in addition are installed in frame (9) and upward are fixed on the cement support plane by four supporting legs (10), guarantee the steady of running.For preventing moving horizontally of roller screen tube, there is a small wheel that is fixed on the frame to contact at roller screen tube port of export dead turn place with the dead turn end face, overcome axial force.The hood that tube is outer, the first half can be raised and be convenient to repair and change sieve plate, and the bottom is fixed, and is making funneling near the screen bottom place, so that the material of concentrating screen cloth to fall.Erect one at the frame two ends and be higher than roller screen tube axis by its position of fixedly long tube (11) in the roller screen tube, be furnished with a plurality of hooks on the long tube with sitting in the roller screen tube not contact fixedly, collude and hang many hoisting chains (12), one end colludes an end and freely dangles, and its length should be as the criterion not contact sieve plate.One end of roller screen tube has charging aperture (13), and discharging opening (14) is arranged at the bottom of the other end, has a light-weight articles to collect mouthful (15) at the middle part of discharge port end.The rubbish of preliminary screening is sent in the roller screen tube by charging aperture, and rubbish flows on the sieve plate of roller screen tube with the at the uniform velocity revolution of roller screen tube, because the roller screen tube has certain angle of inclination, rubbish can flow to the port of export by going into entrance point.In this process, the rubbish that is put together by sieve plate and quilt is satisfactory.The rotation that does not thereupon stop, bulky grain and some lightweight bulk article have been detained on the sieve plate, moving to the port of export, rubbish by in the tube between the sieve plate angle fall by deadweight after lifting eminence, in falling process, the collection mouth at port of export place can be collected paper, plastics and other light-weight articles go-on-go owing to connecting a negative pressure source, the chain that hangs in the tube, relative to rotating of cylindrical shell, play helping to stir, the effect of collision rolling rubbish prevents rubbish unnecessary winding in rolling, guarantee to twine stifledly, finish the screening of rubbish and handle.

Claims

1, a kind of garbage disposal screening plant, it comprises motor, reductor and frame, it is characterized in that: the roller screen tube that the horizontal rotation of four rolling rubber tires and its support is housed on the frame plane, screen drum is made of garden, two ends shape dead turn and middle rigid frame, the polylith sieve plate is fixed on the framework, charging aperture is arranged at roller screen tube one end top, discharging opening is arranged at other end bottom, there is an openable hood horizontal roller screen tube outside, frame two ends frame one and is positioned at roller screen tube axis top by the fixedly card pipe range amount in the roller screen tube, many hoisting chains are housed on the pipe, have one to collect mouth at roller screen tube discharge port end middle part.

2, according to the described device of claim 1, it is characterized in that: the axis of roller screen tube and horizontal plane have a slanted angle.
