Description

Steel piece separator {A steel piece separator}

The present invention relates to an iron slab sorter for sorting out iron shards included in construction waste raw materials including iron slabs and sand, etc., by overturning or scattering the raw construction wastes fed through a hopper and transported by a belt to obtain raw construction wastes. It relates to an iron piece sorter configured to sort out not only the surface but also iron pieces hidden in construction waste in the process of being conveyed by a belt.

In modern times, bridges and roads, including various buildings, are aging, and reconstruction or redevelopment is being actively promoted in many areas to improve housing culture. In this process, a large amount of construction waste is inevitably generated, and when the waste is buried as it is, a large area is required and a correspondingly enormous cost is required.

Representative construction waste materials include soil, waste bricks, steel bars, asbestos, waste synthetic resins, etc. These materials are inevitably adversely affecting the surrounding environment, so measures are being taken to recycle the wastes. Of course, various devices are being developed.

Usually, the waste generated during the dismantling of construction structures is collected in a designated place and reproduced as a high-quality resource through a series of treatment processes such as a crushing process and a foreign matter screening process, and then separated for incineration or recycling and used in various industrial fields. can be utilized

In relation to such a sorting device for construction waste materials, in the "magnetic sorter" disclosed in Korean Patent Registration No. 0432535, a magnet body with a built-in electromagnet is supported by a frame, and at the same time, a circulating belt is supported by a main roller and an auxiliary roller to the magnet body. It circulates around and is configured by attaching scrapers to the circulation belt at regular intervals.

However, in such a magnetic separator, the size of the magnet body is increased in order to extend the transport distance of ferrous metal attached to the lower surface of the circulation belt, and accordingly, the size of the magnetic separator itself must be significantly increased, and the circulation belt is made of non-woven fabric. There is a disadvantage in that the circulation belt is torn when ferrous metal is attached to the circulation belt with strong force by the electromagnetic force.

In addition, in the case of the "magnetic sorting device using a magnetic drum" known as Patent Registration No. 1269151, when the weak magnetic fragments stick to the upper surface of the circular drum by the magnetic force of the permanent magnet and continuously rotate, and are placed on the lower side of the circular drum It falls downward by its own weight, and the non-magnetic fragments are separated far outward by the rotational force of the circular drum so that weak magnetic fragments and non-magnetic fragments are separated.

In this method, since the circular drum and the fragments make point contact, the weak magnetic fragments do not adhere well to the surface of the circular drum, and the weak magnetic fragments also fall outward due to the rotational force of the circular drum. Even if it is, there is a case where weak magnetic fragments and a large amount of non-magnetic fragments are mixed.

In order to solve this problem, in Patent Registration No. 10-2152054 (August 31, 2020), in claim 1, "Conveyor belt for continuously transporting recycled aggregate produced by crushing raw construction waste into fine pieces in the horizontal direction ( 20), a hopper 30 for guiding the recycled aggregate from the conveyor belt to the processing path, and a damper structure 40 for sorting and separating the stainless steel included in the recycled aggregate, the hopper 30 ) Inside, the guide plates 31a and 31b are arranged to face each other in an inclined state so that the recycled aggregate transferred from the conveyor belt 20 is supplied to the damper structure 40 side, and the damper structure 40 includes an exterior housing 41, a magnet drum 42 installed to rotate by driving a motor within the exterior housing, and a scraping unit 43 for removing residue adhering to the surface by elastically adhering to the surface of the magnet drum 43. ) and discharge passages 44a and 44b for dividing and dispersing the sorted recycled aggregates formed on the lower surface of the exterior housing, respectively, and a diameter in the longitudinal direction around the outer circumference of the magnet drum 42. Different hollow permanent magnets 46a and yokes 46b are repeatedly arranged and fixedly installed by covers 47b at both ends, and at the same time, a protective ring 48 is covered around the outer circumference of the permanent magnet, and the yoke Permanent magnets 46a disposed on both sides of (46b) are arranged so that the same poles face each other, and the magnet drum 42 is vertically spaced in the outer housing 41 with its central axis spaced apart in the upward and downward directions. At the same time as being arranged, guide plates 50a and 50b for dropping the stainless steel separated from the recycled aggregate are installed around each magnet drum, and the scraping unit 43 removes the magnetic drum 42 from the exterior housing 41. A casing 51 mounted in a horizontal direction toward the central axis, a contact piece 52 installed at one end of the casing and in contact with the surface of the magnet drum 42, It consists of a screw shaft 53a and a spring 53b for providing elasticity to the contact piece, and the contact piece 52 has a slide rod 55 in the casing 51 to have fluidity through the connecting pin 54 Stainless steel sorting equipment from construction waste material, characterized in that a fixing cap 56 is installed to maintain the spring 53b inserted into the screw shaft 53a at the same time as being mounted on the screw shaft 53a.

However, the above conventional registration patent No. 10-2152054 stainless steel sorting equipment from construction waste materials uses the magnetic drum 42 installed in multiple stages in the housing to sort stainless steel, so it is space-saving, but However, when the raw construction waste material includes the raw construction waste material formed by clumping due to the iron slab and the soil around the iron slab, there is a problem that the magnetic force on the iron slab cannot overturn or scatter the clumped construction waste material.

In addition, since the stainless steel sorting equipment in the construction waste raw material of the above conventional registered patent No. 10-2152054 performs the sorting operation for stainless steel using only the magnetic drum 42 installed in multiple stages in the housing, the construction waste raw material When it contains construction waste material formed by aggregation due to the soil contained therein, the magnetic force for the iron piece does not reach due to the soil included in the agglomerated construction waste material, so the iron piece cannot be sorted out only by the magnetic drum 42 installed in multiple stages. There was a problem.

In addition, the stainless steel sorting equipment from the construction waste of the above conventional registered patent No. 10-2152054 performs the sorting operation for stainless steel using only the magnetic drum 42 installed in multiple stages in the housing, and before the magnetic drum 42 In the process of transporting construction waste materials on the conveyor belt 2, there is a problem in that stainless steel sorting, that is, iron piece sorting, is incomplete because stainless steel is not sorted.
