Problems solved by technology

At present, China's domestic waste classification legislation is not perfect, and the waste composition is complex, and various corrosive substances and hard objects are mixed in it, which puts forward higher requirements for the treatment device
Therefore, there is no garbage extrusion separation device that is suitable for the dry-wet separation of domestic garbage and meets the requirements of resource recovery.

Embodiment 1

[0025] Such as figure 1 , 2 , 3 and 4, an extrusion separation device for dry-wet separation of municipal solid waste, including feeding mechanism 1, pre-pressing mechanism 2 and 2', extrusion mechanism 3 and 3', discharge mechanism 4, body 5. The rotating mechanism 6 and the driving mechanism 7.

[0026] The feeding mechanism 1 is a hydraulic cylinder propulsion structure; the pre-pressing mechanism 2 and 2' is a pair of 10Mpa-50Mpa hydraulic cylinder structure distributed on top; the extrusion mechanism 3 and 3' is a 50Mpa-100Mpa hydraulic cylinder distributed on top structure, that is, a pressurized hydraulic cylinder, and a hydraulic cylinder structure that can withstand high pressure on the top; the discharge mechanism 4 is a hydraulic cylinder structure. The rotating mechanism 6 is arranged on the central axis inside the machine body 5 . A feeding mechanism 1, a pre-pressing mechanism 2 and 2', an extruding mechanism 3 and 3', a discharge mechanism 4 and a driving mec...

Embodiment 2

[0030] Such as Image 6 , 7 As shown, another extrusion separation device for dry-wet separation of MSW is different from Embodiment 1 in that: the outer circumference of the turntable 9 is provided with teeth, and the rotation mechanism 6 and the drive mechanism 7 are arranged in parallel.

[0031] The driving mechanism 7 includes a reducer 13 and a hydraulic motor 14. The reducer 13 is arranged inside the body 5, and the hydraulic motor 14 is arranged outside the body 5. The output shaft of the hydraulic motor 14 is connected to the shaft of the reducer 13, and the reducer 13 adopts a gear Box, the rotation of the turntable 9 is realized by means of the gear of the gear box meshing with the teeth on the turntable 9, and the parallel arrangement of the rotation mechanism 6 and the drive mechanism 7 is realized.

[0032] The working process of the present invention: the feeding mechanism 1 transfers the garbage into the device and sends it to the working surfaces of the pre-p...

Abstract

The invention relates to waste disposal equipment, in particular to an extruding-separating device for dry and wet separation of municipal solid waste. The extruding-separating device solves the problem that dry and wet separation of municipal solid waste in China cannot meet the requirement for recycling resources. A feeding mechanism, a pre-pressing mechanism, an extruding mechanism and a discharging mechanism are arranged on the outer side of a machine body, the feeding mechanism and the pre-pressing mechanism are arranged perpendicular to each other, the pre-pressing mechanism, the extruding mechanism and the discharging mechanism are arranged in parallel, the axis of the pre-pressing mechanism, the axis of the extruding mechanism and the axis of the discharging mechanism are located in the same circumferential line and are arranged at 120-degree intervals, a rotating mechanism is arranged on the central axis in the machine body, the rotating mechanism and a driving mechanism are arranged coaxially or in parallel, and the driving mechanism is arranged on the outer side of the machine body. The extruding-separating device can ensure dry and wet separation of municipal solid waste in China, the water content of the dry municipal solid waste is lower than 30%, and outstanding improvements are made in the respects of waste adaptability, equipment maintainability, equipment reliability, cost reduction and the like.

Description

technical field [0001] The invention relates to a garbage treatment device, in particular to an extrusion separation device for dry-wet separation of municipal domestic garbage. Background technique [0002] Domestic waste disposal is still dominated by landfill and incineration, which inevitably brings secondary pollution. Recycling after garbage disposal is a very promising solution to the garbage problem. [0003] The high-pressure extrusion separation process is a new process for treating garbage and recycling resources. In this process, the garbage treatment equipment separates the garbage from wet and dry. When the moisture content of dry solid garbage (inorganic part) is lower than 30%, it can be prepared as garbage-derived fuel; wet liquid garbage can be processed to produce biogas. It can be seen that the high-pressure extrusion treatment of garbage, the completion of dry-wet separation and the garbage treatment equipment that ensures the moisture content of dry g...
