Description

Construction waste recovery device

Technical Field

The utility model belongs to the field of building construction, and particularly relates to a device for recycling and treating building waste.

Background

The construction waste refers to the collective name of dregs, waste concrete, waste masonry and other waste generated by people in the production activities of construction industries such as removal, construction, decoration, repair and the like; the construction waste can be classified into engineering residue soil, decoration garbage, removing garbage, engineering slurry and the like according to the generation source; the construction waste materials are classified according to the composition, and can be divided into slag soil, concrete blocks, crushed stone blocks, brick and tile fragments, waste mortar, slurry, asphalt blocks, waste plastics, waste metals, waste bamboo and wood and the like.

The recycling of the construction waste is to crush the construction waste into aggregate, screen and remove impurities to form building materials with certain particle size for recycling; some existing construction waste treatment equipment simply smashes the operation with the construction waste, can not classify the raw materials after smashing, because the constitution part of construction waste is mostly metal waste, wood waste and waste stone, and the recovery mode of three is different, does not separate it can influence the efficiency of follow-up recovery processing.

Aiming at the separation of metals in construction waste, china patent application No. 2022106615803 discloses a construction waste smashing and recycling device, the recycling device introduces a transfer assembly, wherein the transfer assembly comprises a rotating magnetic chuck and a scraping plate positioned at the lower part of the magnetic chuck, the magnetic chuck adsorbs iron metals on the transmission assembly and transfers the iron metals to a separating opening, the iron metals are scraped from the bottom of the magnetic chuck through the scraping plate, and the separation of the iron metals in the construction waste is realized.

Disclosure of Invention

The utility model aims at solving the problems of treating construction waste in the prior art and providing a construction waste recycling device capable of separating metal substances of the construction waste and classifying different particle sizes.

The utility model solves the technical problems by adopting the technical scheme that: the building waste recovery device comprises a shell, wherein a crushing cavity and a screening cavity are sequentially formed in an inner cavity of the shell from top to bottom, a feed inlet is formed in the upper part of the crushing cavity, a blanking pipe is arranged in the lower part of the crushing cavity, a material receiving pipe is arranged in the upper part of the screening cavity, the diameters of the blanking pipe and the material receiving pipe are the same, the blanking pipe and the material receiving pipe are opposite from each other up and down, a separation pipe is sleeved between the blanking pipe and the material receiving pipe, a separation cavity is formed between the separation pipe and the blanking pipe, the blanking cavity is communicated with the blanking cavity, a discharge cavity is formed between the screening cavity and the separation pipe, the discharge cavity is communicated with the separation cavity, and the discharge cavity is provided with a discharge port;

the screening cavity mainly comprises an upper shell and a lower shell, a plurality of screening shells are arranged in the screening cavity, the upper shell, the lower shell and the screening shells are conical shells, screening holes are formed in the screening shells, the screening shells are separated from the screening cavity to form a plurality of screening subchambers, and each screening subchamber is provided with a corresponding discharge hole;

the crushing cavity is internally provided with a crushing roller which is connected with the driving assembly;

and a plurality of electromagnets are arranged on the outer wall of the separation tube corresponding to the blanking cavity, distributed along the circumferential direction of the separation tube, and connected with a controlled current source.

Optionally, two screening shells are arranged in the screening cavity, and are distributed from top to bottom in sequence, and the 2 screening shells are separated from the screening cavity to form three screening subchambers.

The application mode and the principle of the utility model are as follows: connecting a controlled current source and a driving assembly with voltage, driving a crushing roller in a crushing cavity by the driving assembly to start crushing work, providing controllable current for an electromagnet on the outer wall of a separation pipe by the controlled current source, throwing the construction waste into the separation pipe from a feed inlet, and crushing, separating and screening the construction waste;

the principle of the utility model is that the construction waste is crushed by the crushing roller in the crushing cavity, the crushed construction waste enters the blanking pipe, passes through the blanking cavity, enters the receiving pipe, enters the screening cavity from the receiving pipe, and is subjected to particle screening classification in the screening cavity;

when the crushed building waste passes through the blanking cavity, metal substances in the building waste can be influenced by the magnetic force of the electromagnet on the outer wall of the separating pipe, enter the separating cavity from the blanking cavity and are adsorbed on the inner wall of the separating pipe, when the controlled current source stops supplying current to the electromagnet, the electromagnet loses the magnetic force, the metal substances on the inner wall of the separating pipe fall off, fall into the discharging cavity under the influence of gravity and are discharged through the discharging port of the discharging cavity;

after crushed building waste falls into the screening cavity, firstly enters the screening subcavities of the upper layer, falls on the conical screening shell, falls under the action of gravity, and in the falling process, small-particle building waste enters the next-layer cavity through the sieve holes on the screening shell, does not fall into particles of the next-layer cavity, is discharged through the discharge hole of the current screening subcavities, and is screened and classified into different particle sizes through the multi-layer screening subcavities.

Compared with the prior art, the utility model has the following beneficial effects: the utility model has simple structure, can effectively separate metal substances in the construction waste, and can screen and classify the size of crushed particles.
