Abstract

The utility model relates to the garbage treatment technique, particularly a garbage crusher making the crushing treatment on domestic garbage. The utility model is characterized in that a crushing device is composed of a main shaft and a plurality of rotary discs, a plurality of sets of movable knife rows and a plurality of fixed knife rows fixed on the main shaft, wherein a plurality of sets of movable knife rows are hinged between the two rotary discs along the radial direction; the fixed knife rows are arranged on a first tangent point of the movable knife and are intercrossed with the movable knife rows, arranged and matched, and however, a certain gap is kept, and a discharge hole is a non-sieve open type. The utility model aims to provide a garbage crushing machine capable of crushing the domestic garbage. The utility model has the advantages of favorable garbage crushing effect, smooth feeding, timely discharge, pneumatic separation effect, etc.

Description

Refuse grinder

Affiliated technical field

The utility model relates to technology of garbage disposal, particularly a kind of refuse grinder that house refuse is carried out break process.

Background technology

Domestic waste is innoxious, minimizing, recycling treatment, is the important component part that realizes China's strategy of sustainable development.In the process that rubbish " three change " is handled, be wherein important step as the preliminary treatment fragmentation, and refuse grinder is exactly a key equipment wherein, the quality of its performance directly has influence on the overall process of whole garbage disposal.Owing to comprise fragility and flexible rubbish material in the house refuse, any simple breaker all is difficult to simultaneously they be handled at present.

Summary of the invention

The purpose of this utility model provides a kind of broken broken machine of rubbish that can broken house refuse.

In order to achieve the above object, the utility model adopts following technical solution: a kind of refuse grinder, comprise support, breaker, it is characterized in that breaker by main shaft, be fixed on some rotating disks on the main shaft, some groups of moving knife rows and stationary knife row and form, radially hinged some groups of moving knife row between two rotating disks, stationary knife row be located on first point of contact of moving knife, and arrange mutual cross arrangement with moving knife and cooperate, keep certain clearance, discharging opening is open for there not being sieve.

During disintegrating machine work, rubbish is fed by ribbon conveyer, moving knife under the effect of centrifugal inertial force to around open, the rubbish that enters in the casing is smashed, and the block that wherein proportion is bigger (stone, brick, tile fragment etc.) is in the process of fragmentation, owing to obtain kinetic energy, at full speed impact the also mutual bump of stationary knife and make rubbish further broken; Simultaneously, moving knife and stationary knife are thrown flexible rubbish to part is light on the one hand, shear as polybag, duds thing, cotton-wool, on the other hand to fragility rubbish impact, grinding.Rubbish is after inlet moving knife, stationary knife are just broken, the tiny wind-force that is produced by the rotating disk rotation blows out to be seen off, part does not reach dimensional requirement, still stay on the inlet stationary knife, the moving knife that is followed up later hits repeatedly, under composite force effects such as shearing, impact, grinding, finally incoherent, until drawing off.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a present embodiment left side pseudosection.

Fig. 2 is that Fig. 1 is along the A-A profile.

The specific embodiment

As shown in Figure 1 and Figure 2, present embodiment comprises support (5), breaker, breaker by main shaft (3), be fixed on some rotating disks (2) on the main shaft, some groups of moving knife rows (4) and stationary knife and arrange (6) and form.Between two rotating disks radially by the hinged some groups of moving knife rows of bearing pin (8) (4), hinged moving knife row (4) be four groups, be " ten " type layout.All be provided with stationary knife row (6), (9) respectively in charging aperture (1) below and discharging opening (7) the place ahead, and arrange mutual cross arrangement with moving knife and cooperate, the maintenance certain clearance forms two fracture area domain spaces.Charging aperture is a vertical, and it is smooth and easy that rubbish is entered, and can not cause the putty phenomenon, and discharging opening (7) is open for there not being sieve, and the rubbish after the fragmentation is in time discharged, can stuck machine.

During disintegrating machine work, rubbish is fed by ribbon conveyer, moving knife come under the effect of centrifugal inertial force to around open, rubbish is in first area of space, passive blade row and first stationary knife row in time carry out just broken, moving knife and stationary knife are on the one hand to the flexible rubbish of the light throwing of part, shear as polybag, duds thing, cotton-wool, on the other hand to fragility rubbish impact, grinding, and the block that wherein proportion is bigger (stone, brick, tile fragment etc.) is in the process of fragmentation, owing to obtain kinetic energy, at full speed impact the also mutual bump of stationary knife and make rubbish further broken.Rubbish after just breaking enters in second broken area of space, and passive once more blade row and second stationary knife row carry out carefully broken, further improve crushing effect.The tiny wind-force that is produced by the rotating disk rotation blows out sees off, and part does not reach dimensional requirement, still stays on the stationary knife row, and the moving knife that is followed up later hits repeatedly, and is finally incoherent under composite force effects such as shearing, impact, grinding, until drawing off.

Because moving knife row is freely to hang, when running into the material that can not smash, moving knife just turns round around bearing pin, thereby avoids damaging machine, plays good protective effect.

In sum, the utility model compared with prior art has the following advantages:

1, charging is smooth and easy, and discharging is timely.

2, refuse breaking is effective.

3, because brittle material is different with flexible material proportion, at the wind-force of turntable rotation generation Effect is lower, can automatically separate brittle material and flexible material, has the selection by winnowing effect.

4, the function that has the protection machine.

Claims

1, a kind of refuse grinder, comprise support (5), breaker, it is characterized in that breaker by main shaft (3), be fixed on some rotating disks (2) on the main shaft, some groups of moving knife rows (4) and stationary knife and arrange (6) and form, radially hinged some groups of moving knife rows (4) between two rotating disks, stationary knife row (6) is located on first point of contact of moving knife, and arrange mutual cross arrangement with moving knife and cooperate, keeping certain clearance, discharging opening (7) is open for there not being sieve.

2, refuse grinder according to claim 1 is characterized in that first stationary knife row (6) is located on the support (5) of charging aperture (1) below.
