Description

The old refuse grinder of drum-type

Technical field

The utility model relates to a kind of special refuse grinder at old formula rubbish.

Background technology

Before domestic waste is made all processing and utilizing, all need rubbish is done broken preliminary treatment, and the quality of decision crushing effect, disintegrating machine is crucial.Existing refuse grinder, as China's patent No.: 200620032719.4 disclosed a kind of house refuse half wet crushing mills, its structure is as shown in Figure 3: comprise base 20, the casing 23 of band charging aperture 21 and discharging opening 22, rotating shaft 24 in the casing 23, be loaded on the crushing mechanism in the rotating shaft 24, the transmission device 30 that is connected with rotating shaft 24, its crushing mechanism comprises and is installed in the hammer leaf location-plate 25 that the several piece in the rotating shaft 24 is provided with at interval, all hammer leaf location-plates 25 link to each other by several bearing pins 26, on the bearing pin 26 between the adjacent two hammer leaf location-plates 25, several piece hammer leaf 27 is installed, the tooth plate 28 of inner surface indentation is installed at casing 23 inwalls, also be fixed with a scraper plate 29 on every hammer leaf location-plate 25, all scraper plates 29 are axially being arranged twist; Transmission device 30 drives rotating shaft 24 rotations during work, promoting rubbish by spiral helicine scraper plate 29 advances, by the strike of hammer leaf 27 and and tooth plate 28 between powerful collision, extruding and grind and realize pulverizing, in order to make rubbish be unlikely to pass from the gap between hammer leaf 27 and the tooth plate 28 and cause crushing effect bad, so the spacing between the hammer leaf 27, between hammer leaf 27 and the tooth plate 28 can not be too big, could carry out extruding cutting by force like this to the rubbish by wherein, play fragmentation preferably; But this structure is unsatisfactory for the crushing effect of old rubbish, because old rubbish has low but the characteristics that viscosity is strong especially of intensity hardness, because between the hammer leaf 27, hammer leaf 27 with spacing between the tooth plate 28 narrow and small and easy generation obstruction, cause crushing efficiency low, even lost efficacy, can not solve the broken problem of old rubbish well.

The utility model content

The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provides a kind of drum-type old refuse grinder, and it has good crushing effect to old rubbish.

The purpose of this utility model is achieved in that

The old refuse grinder of a kind of drum-type, comprise casing, rotating shaft in it, crushing mechanism in the rotating shaft, the transmission device that is connected with rotating shaft, it is characterized in that described casing is the cylinder that is provided with axial feed inlet and discharging opening, inner wall of rotary drum is provided with several flights of arranging in the shape of a spiral, cylinder is provided with at least two group support roller assemblies outward, and be installed with gear ring at cylinder outer wall, gear ring cooperates with gear on the one speed reducer output shaft, input shaft of speed reducer links to each other with Rolling motor, the compartment of terrain is installed with two bracing frames in the cylinder, and described rotating shaft two ends are installed on the bracing frame by bearing;

The course of work of the present utility model is: rubbish material enters in the cylinder from charging aperture, Rolling motor drives the cylinder rotation by decelerator and gear ring, flight is with the past cylinder top of material web, the mechanism that is broken when falling impacts, falls into the cylinder bottom, material is taken up, falls by flight once more, and carried to discharging opening, so circulation realizes old material is carried out fragmentation, until discharging from discharging opening;

As further improvement of the utility model, described inner wall of rotary drum charging aperture place is provided with equally distributed several flow distribution plates; Can make material enter cylinder equably, improve fragmentation quality;

As further improvement of the utility model, the bending of the tip of described flight, it is folded to consistent with the direction of rotation of cylinder; Rubbish material can be taken up and taken to higher position and fall again, improve fragmentation quality;

As further improvement of the utility model, described several flights are equidistant evenly layout on axial and circumferential; Can make the distribution of rubbish more even, further improve fragmentation quality;

In sum, the utility model need not extruding, grinds because fragmentation is carried out in the strike of the broken mechanism of breaking, and the spacing between crushing mechanism and the cylinder is bigger, is difficult for stopping up losing efficacy; Flight can realize to material repeatedly, broken repeatedly, have good crushing effect.
