Abstract

The invention discloses a garbage smashing and screening ball mill and a use method thereof. The garbage smashing and screening ball mill is characterized in that a discharging end cover of an existing grate ball mill is removed, a discharging grate plate is exposed, and a large hole is formed in the center of the discharging grate plate and externally connected with a shaft screen; garbage and water are delivered into the ball mill to be smashed at the same time, light garbage which cannot be easily smashed overflows from the large hole in the center of the discharging grate plate to the shaft screen so as to be discharged, and water can be sprayed to the shaft screen at the same time to clean the light garbage; perishable garbage and heavy garbage which can be easily smashed are discharged from seams in the discharging grate plate.

Description

A kind of garbage crushing screening ball mill and using method thereof

Technical field

The invention belongs to Solid Waste Treatment technical field, it is adaptable to the needs of garbage disposal, the rubbish concept being previously mentioned in the present invention contains mixed consumer waste, changing food waste, rubbish from cooking.

Background technology

The feature of rubbish is moisture content height, complicated component, and its composition can be divided three classes: light rubbish, weight rubbish, perishable rubbish.

Light rubbish specifically includes that plastics, bamboo wood, textile etc..

Perishable rubbish specifically includes that food garbage, waste paper etc..

Weight rubbish specifically includes that masonry sand, concrete block, glass, pottery, metal etc..

Current technology of garbage disposal is except burning and except landfill, and other technology is required for first rubbish being pulverized, sorts, cleans, and then just can carry out the utilization of resources；Owing to msw water content is high, complicated component, it is difficult to pulverizing, sorting, cleans, cause that this kind of technology is difficult to large-scale promotion application.

Summary of the invention

The invention aims to provide a kind of method and apparatus that can solve garbage crushing, sorting, a cleaning difficult problem.

Ball mill is Universal disintegrating equipment, is mainly used in the pulverizing of inoganic solids, is characterized in not being afraid of material water ratio height, complicated component, can be carried out pulverizing, and treating capacity is big, durable, operating cost is low, can meet the needs of extensive process；But owing to msw water content is high, complicated component, the structure of existing ball mill is difficult to meet it and pulverizes requirement, it is necessary to transformed.

Present disclosure is: removed by the crusher discharge end cover of existing grate ball mill, exposes discharge grate, opens a macropore at discharge grate center, the external shaft screen of macropore；Rubbish and water being simultaneously fed in this ball mill and pulverize, the light rubbish not easily pulverized is discharged from discharge grate central major aperture overflow to shaft screen, can to shaft screen water spray, light rubbish be carried out simultaneously；Perishable rubbish and the weight rubbish easily pulverized are discharged from the gap of discharge grate.

The invention have the advantage that in ball mill, water is few, what be conducive to perishable rubbish pulverizes the cleaning with light rubbish；Shaft screen is installed on ball mill and rotates, and forms a rotary screen, saves additional cleaning screen subset.

Accompanying drawing explanation

Accompanying drawing 1 is the population structure schematic diagram of one embodiment of the invention.

Detailed description of the invention

As shown in Figure 1, in one embodiment of the invention, the present invention includes: ball mill 1, discharge grate 2, gap 3, taper shaft screen 4, ball mill import 5, grate central major aperture 6.Using method is: rubbish and water enter ball mill 1 through ball mill import 5, and the light rubbish not easily pulverized is discharged from discharge grate central major aperture 6 overflow to taper shaft screen 4, and spray water to taper shaft screen 4 is carried out light rubbish simultaneously；Perishable rubbish and the weight rubbish easily pulverized are discharged from the gap 3 of discharge grate.

Claims

1. a garbage crushing screening ball mill and using method thereof, it is characterised in that: the crusher discharge end cover of existing grate ball mill is removed, exposes discharge grate, open a macropore at discharge grate center, the external shaft screen of macropore；Rubbish and water being simultaneously fed in this ball mill and pulverize, the light rubbish not easily pulverized is discharged from discharge grate central major aperture overflow to shaft screen, can to shaft screen water spray, light rubbish be carried out simultaneously；Perishable rubbish and the weight rubbish easily pulverized are discharged from the gap of discharge grate.
