Construction waste treatment device

Abstract

The invention discloses a construction waste treatment device. The device comprises a conveying frame, a conveyor body is fixedly arranged at the top of the conveying frame, rotating mechanisms are arranged on the two sides of the conveyor body; an iron removing mechanism is arranged on one side of the top of the rotating mechanism; a driving mechanism is arranged at the bottom of the rotating mechanism; the iron removing mechanism comprises a transverse plate; a plurality of sets of open holes distributed at equal intervals are formed in the bottom end of the transverse plate, sleeves are fixedly arranged on the inner walls of the open holes, threaded rods are connected to the inner walls of the sleeves in a threaded penetrating mode, the tops of the threaded rods are sleeved with nuts ina threaded mode, magnetic teeth are fixedly arranged at the bottom ends of the threaded rods, the bottom ends of the magnetic teeth are smooth curved surfaces, the rotating mechanism comprises a cylinder, and a vertical rod is slidably inserted into the cylinder. Construction waste crushed on a conveyor can be shifted and deironed alternately through the iron removing mechanisms on the two vertical rods, the iron removing effect is good, once the magnetic teeth break down, the magnetic force is reduced or disappears, the broken-down magnetic teeth can be detached and replaced with new magnetic teeth, normal iron removing of the construction waste is not affected, and convenience and trouble saving are achieved.

Description

technical field [0001] The invention relates to the field of waste treatment devices, in particular to a construction waste treatment device. Background technique [0002] Construction waste is solid waste generated during the process of new building, reconstruction, expansion or demolition of buildings. Construction waste has the following impacts: [0003] (1) Affecting air quality With the continuous development of cities, a large amount of construction waste is piled up randomly, which not only occupies land, but also pollutes the environment, and directly or indirectly affects air quality; [0004] (2) The vicinity of the construction site is mostly a temporary storage place for construction waste. Due to the convenience of construction and the lack of proper protective measures, under the influence of external factors, the construction waste pile collapses, blocking the road and even rushing to other buildings. phenomenon occurs from time to time; [0005] (3) After ...

AI Technical Summary

Problems solved by technology

[0003] (1) Affecting air quality With the continuous development of cities, a large amount of construction waste is piled up randomly, which not only occupies land, but also pollutes the environment, and directly or indirectly affects air quality;

[0004] (2) The vicinity of the construction site is mostly a temporary storage place for construction waste. Due to the convenience of construction and the lack of proper protective measures, under the influence of external factors, the construction waste pile collapses, blocking the road and even rushing to other buildings. phenomenon occurs from time to time;

[0005] (3) After long-term exposure to the sun and rain, the harmful substances in the garbage (including the polycyclic aromatic hydrocarbons released from the paint, coating and asphalt in the urban construction waste) seep into the soil through the landfill leachate, As a result, a series of physical, chemical and biological reactions occur, reducing soil quality;

[0006] (4) Under the action of various external forces, the urban construction waste piled in the open air will also enter the nearby soil, changing the material composition of the soil, destroying the structure of the soil, and reducing the productivity of the soil

[0012] Common iron removers are basically located on the conveyor, using the transmission belt of the magnetic separator to absorb the iron doped in the crushed construction waste, the iron removal is relatively simple, and some iron crushers are buried in the crushed construction waste inside, it is not easy to completely absorb, and the iron removal effect is not good, and when the magnetic separator belt fails, the entire magnetic separator belt needs to be disassembled, which affects the normal iron removal of construction waste, affects the iron removal effect and the progress of garbage treatment
