Abstract

The invention relates to the field of waste treatment, in particular to a waste extruder. A technical scheme is adopted in the invention as follows in the waste extruder, a plurality of groups of upper and lower compression rollers are arranged on a frame; the distance between the upper and lower compression rollers of each group is set from one port of a feed port to one end of a discharge port from big to small; a workbench plate is tiled on the frame; and the upper roller surface of the lower compression roller is exposed on the upper plate face of the workbench plate. According to the technical scheme, after the waste is extruded by the compression rollers, the waste can achieve a dryness degree of over 90 percent, so that the energy is saved, and the roasting cost is reduced.

Description

A kind of rubbish extruder

Technical field

The present invention relates to the garbage disposal field, a kind of rubbish extruder of specific design.

Background technology

Along with The development in society and economy, living standards of the people improve constantly, and variation has also taken place the composition of domestic waste, mainly showing as content of organics increases, and inorganic component descends, and the refuse thermal value amount increases, this also just helps rubbish being turned waste into wealth burning electricity generation.

Domestic waste generally will be done simple classification before burning, for the waste incineration production procedure is delivered to roasting and the constant temperature virus killing lays the foundation smoothly.But in the domestic waste, especially the moisture in the changing food waste is higher, generally reach more than 85%, this just needs rubbish before burning electricity generation it to be carried out dry draining processing, general at present the employing burned the heat energy oven dry in the kiln, yet so just need to consume a large amount of heat energy in the kiln, have a strong impact on generating efficiency.

Summary of the invention

The purpose of this invention is to provide a kind of rubbish extruder, can carry out dry draining to rubbish effectively and handle.

For achieving the above object, the present invention by the following technical solutions, a kind of rubbish extruder, some groups of upper and lower pressure rollers are set on the frame, roll gap between every group of upper and lower pressure roller is by big and little setting to discharging opening one end from feeding mouth one end, the working plate that has tiling to be provided with on the frame, the upper end roll surface of lower compression roller is revealed in the upper head plate face of working plate.

By above technical scheme, pressure roller can reach the aridity more than 90% after to the rubbish extrusion process, has not only saved the energy but also reduced and cured cost.

The specific embodiment

A kind of rubbish extruder, some groups of upper and

lower pressure rollers

21,22 are set on the frame 10, roll gap between every group of upper and

lower pressure roller

21,22 is by big and little setting to discharging opening one end from feeding mouth one end, the working plate 30 that has tiling to be provided with on the frame 10, the upper end roll surface of lower compression roller 22 is revealed in the upper head plate face of working plate 30.Upper and

lower pressure roller

21,22 provides powered rotation by reductor, each is organized and adopts the mode of chain transmission or band transmission to connect between the rotating shaft of pressure roller, every group of pressure roller pushes because the centrifugal force of the generation that rotatablely moves can be pushed to rubbish between next group pressure roller along working plate 30 easily in pressing waste.

Further, described working plate 30 is to be made of the pallet unit that is arranged between the lower compression roller 22 at interval, so neither can influence the squeezing effect of 21,22 pairs of rubbish of upper and lower pressure roller, also can support effectively and guarantee that rubbish is transported to discharging opening from feeding mouth.

Column 11 is set on the frame 10, fixes the bearing block of upper and

lower pressure roller

21,22 on the column 11, be provided for the governor motion 40 that regulating shaft bearing 23 moves up and down between the bearing block 23 of last pressure roller 21 and the column 11.Governor motion 40 is a leading screw and nut mechanism, and the nut 41 of leading screw and nut mechanism is fixed on the column 11, and the thread segment shaft of screw mandrel 42 cooperates with nut 41, and the bearing block 23 of the lower end of screw mandrel 42 and last pressure roller 21 constitutes that above-below directions are spacing, the cooperating of circumferential rotation.

Further, described bearing block 23 comprises pedestal 231 and slide block 232, pedestal 231 and slide block 232 have two kinds of integral structure and split-type structurals, slide block 232 in the split-type structural is positioned at the top of pedestal 231, slide block 232 lower ends connect the upper end of spring 70, and the lower end of spring 70 connects pedestal 231.Slide block 232 offers chute with position, pedestal 231 both sides of the edge and is slidingly matched with column 11 formations, and the bottom bar head of the screw mandrel 42 of leading screw and nut mechanism is mushroom and places the big cavity in the little inside of the oral area that matches with the bar head shapes on the slide block 232.The cavity that matches with screw mandrel 42 bar head shapes on the slide block 232 is the zone that a pair of pressing plate of the recess that is provided with on the slide block 232 and this recess open-mouth setting surrounds, the side edge that two pressing plates recline mutually all has semicircle orifice, and two semicircle orifices constitute the circular hole that directly matches with screw mandrel 42 bar head place bars.Elder generation places the bar head of screw mandrel 42 in the cavity of slide block during assembling, by two block pressur plates it is compressed again, and pressing plate adopts bolting on the upper surface of slide block 232.When the turning handle of rotary screw rod 42, the bearing block that the circumferential screw of the shaft of screw mandrel 42 and the rectilinear motion of above-below direction will drive pressure roller 21 rectilinear motion about in the of 23 is realized the adjusting to last pressure roller 21 height.

Because the roll gap of the upper and

lower pressure roller

21,22 that close feeding mouth goes out is big and extruding degree rubbish is not high, the foreign material in the rubbish generally can not impact the rotating shaft of last pressure roller 21, so select the bearing block of pedestal 231 and slide block 232 integral structures for use; Less and rubbish is crushed substantially near the roll gap of the upper and lower pressure roller at discharging opening place, hard thing in the rubbish foreign material can increase the load of going up pressure roller 21 rotating shafts even cause fracture, so select the bearing block of pedestal 231 and slide block 232 separate type for use, when pressure roller was pressed onto foreign material, spring can be alleviated in the foreign material rigid shock of hard thing to upper and

lower pressure roller

21,22.

In order to be convenient to extruding more, simultaneously also can make things convenient for rubbish later stage burning electricity generation, each pallet unit of working plate 30 is interval with parallel groove on the material direction of advance, circular saw 50 is set in the groove, its card is axial perpendicular to lower compression roller 22, and rubbish also is cut when being extruded.

The bottom of working plate 30 is provided with the hopper 60 of collecting sewage, and the middle part of hopper 60 is provided with filter screen 61, and the lower end oral area of hopper communicates with blow-off line.Rubbish be extruded and cutting process in the sewage that produces along the gap between the roll surface of upper and

lower pressure roller

21,22 and the groove on the working plate 30 flow into the hopper 60 of working plate 30 bottoms, the filter screen 61 at the middle part of hopper 60 can filter the solid particle in the sewage, prevents to stop up blow-off line.

In order to prevent that rubbish from splashing at the sewage that the process that is extruded and cuts produces, and is provided with baffle plate 80 between the roller end of upper and

lower pressure roller

21,22 and the inboard of column 30.

Further the roll surface of described upper and

lower pressure roller

21,22 can be smooth roll or the squeezing effect that is made as concavo-convex raising pressure roller.
