Description

Primary garbage disposal system

Technical Field

The invention relates to a primary garbage disposal system, and belongs to the field of recycling of garbage disposal resources for building decoration.

Background

Traditional artifical letter sorting line of primary rubbish is incomplete to the letter sorting of rubbish, relies on artifical letter sorting, needs artifical long-term operation, and the processing cost of rubbish is also relatively higher.

The bouncing screen used in the sorting line is mainly characterized in that a screen plate is driven by an eccentric shaft, a shaftless drum screen is obliquely installed, and the screen plate is driven to move up and down and back and forth through the eccentric shaft during operation, so that screened materials on the screen plate are shaken and scattered into heavy and rolling 3D material parts (such as plastic bottles, woods, cans and the like) and light and flat 2D material parts (films, papers and paperboards) and undersize material parts (sand and food residues), and the treatment of subsequent procedures is facilitated. Under the action of a driving motor, the bouncing screen is connected with the supporting seat and the screen plate through a driving and driven transmission assembly consisting of a driving shaft, a driven shaft and an eccentric wheel to form a parallel four-bar mechanism, and the screen plate generates reciprocating circular motion similar to bouncing so as to separate materials input from a feed inlet into three types. During operation, the axial flow fan arranged at the tail part of the bouncing screen is matched with the separation of combustible materials, the axial flow centrifugal fan is directly arranged on the bouncing screen frame, and the fan blades are extremely easy to damage due to material winding, material splashing and the like.

The existing bouncing screen is mainly used for treating and sorting household garbage, kitchen garbage after squeezing, paper recycling and other industries; the screen plate has insufficient strength, and the condition that the screen plate is bent, deformed and blocked when the construction decoration garbage is screened; the transmission assembly is not suitable for garbage disposal of building decoration, the existing transmission assembly bearing of the bouncing screen has the defects of more utilization rate, higher failure rate, more combustible materials, woven bags, twines and the like in the large piece of garbage of the building decoration, easy winding of shafts on the transmission assembly, failure shutdown, even damage to the transmission assembly inner bearing and longer maintenance time.

The existing shaft coupling at the motor of the bouncing screen adopts a star-shaped shaft coupling, and the motor still runs when the screen plate is clamped, and the like, so that the damage to the screen plate and the bearing of the bouncing screen is easy to cause.

When screening the primordial building decoration rubbish, because primordial building decoration rubbish composition is complicated, massive combustible content is higher, if not isolate massive combustible, gets into follow-up screening, broken aggregate area, very easily causes equipment card to block up, and shut down clearance time is longer, influences production efficiency, causes equipment to damage even, influences equipment life.
