DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1-Figure 4 The present invention provides the following technical solution: a magnetic separator for recycling construction material waste, including a belt conveyor 1, an electromagnet 2 is fixed inside the belt conveyor 1, and also includes a feeding mechanism 3, and the feeding mechanism 3 includes: a No. 1 side plate 31, a metering bucket 32, a feeding bucket 33, a rotating roller 34 and a No. 1 driving motor 35.

[0047] Further, by Figure 1 and Figure 2As shown, in this embodiment, two feeding mechanisms 3 are symmetrically fixed to the top of the belt conveyor 1, and the metering bucket 32 ​​is fixed between the two No. 1 side plates 31. The metering bucket 32 ​​is a hollow cylindrical structure with a notch at the top, and the bottom of the metering bucket 32 ​​has a discharge port 321. The upper hopper 33 is fixed at the notch at the top of the metering bucket 32. The rotating roller 34 is rotatably installed in the metering bucket 32, and the outer wall of the rotating roller 34 has a plurality of metering grooves 341 evenly spaced along the circumferential direction. The No. 1 driving motor 35 is fixed on the No. 1 side plate 31 to drive the rotating roller 34 to rotate. After adopting the above scheme, when in use, the belt conveyor 1 is started and the electromagnet 2 is energized, and the No. 1 driving motor 35 is started at the same time to drive the rotating roller 34 to rotate, and the building material waste to be deironed is directly put into the upper hopper 33. , or after being crushed and processed, it is put into the upper hopper 33, and the waste building materials pass through the upper hopper 33 and the gap at the top of the quantitative hopper 32 and enter the quantitative slot 341. With the rotation of the rotating roller 34, an equal amount of waste building materials is stored in each quantitative slot 341. When the quantitative slot 341 rotates to coincide with the discharge port 321, the waste building materials are discharged and fall onto the belt of the belt conveyor 1 for transportation. The waste building materials are transmitted by the belt conveyor 1, and the electromagnet 2 has magnetism after being energized, which can attract iron. The iron contained in the waste building materials will be adsorbed on the belt of the belt conveyor 1. The magnetic separator of the present invention ensures that the waste building materials fall more evenly on the belt of the belt conveyor 1 for transportation through quantitative feeding, thereby avoiding the accumulation of waste building materials affecting the adsorption of iron by the belt, and greatly improving the iron removal effect.

[0048] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the outer wall of the rotating roller 34 is in contact with the inner wall of the metering bucket 32, and the size of the metering groove 341 is equal to the size of the top notch of the metering bucket 32. After adopting the above design, it is ensured that the construction waste can fall into the metering groove 341 reliably, and the gap between the rotating roller 34 and the inner wall of the metering bucket 32 ​​is avoided to cause the material to get stuck.

[0049] It should be noted that, through the loading method of the present invention, during the loading process, the rotating roller 34 and the belt conveyor 1 always keep running. Therefore, when the construction waste falls onto the belt of the belt conveyor 1, it will definitely not fall to the same position on the belt, which can effectively avoid the problem of construction waste accumulation affecting iron removal.

[0050] Preferably, by Figure 1 and Figure 3As shown, in this embodiment, an agitation mechanism 4 is also included, and the agitation mechanism 4 includes: a rotating arm 41, a fixed rod 42, a No. 2 drive motor 43 and a rotating cylinder 44. The two rotating arms 41 are symmetrically distributed and rotatably installed on the opposite surfaces of the two No. 1 side plates 31. The fixed rod 42 is fixed between the two rotating arms 41. The No. 2 drive motor 43 is fixed on the No. 1 side plate 31 to drive the rotating arm 41 to rotate. The rotating cylinder 44 is hollowly sleeved on the fixed rod 42. After adopting the above scheme, when working, the No. 2 drive motor 43 is started to drive the rotating arm 41 to rotate, and the rotating arm 41 drives the rotating cylinder 44 to make a circular motion. The rotating cylinder 44 continuously hits the belt of the belt conveyor 1 to make the belt vibrate, which can make the building material waste more evenly transported, avoid the accumulation of building material waste, and improve the iron removal effect.

[0051] It is worth noting that the present invention uses a hollow-type installed rotating cylinder 44 to hit the belt of the belt conveyor 1. In fact, a fixedly installed rotating cylinder 44 can also achieve the same hitting effect, but it is preferred in the present invention because the rotating cylinder 44 will continue to contact the belt for a period of time during the entire process of completing a hit. During this period of time, as the rotating arm 41 rotates, the rotating cylinder 44 will also rotate due to the friction between the belt, converting the sliding friction into rolling, reducing the sliding friction and avoiding wear.

[0052] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, it also includes: a rubber sleeve 45, which is sleeved on the rotating cylinder 44. The rubber sleeve 45 is flexible, and the belt of the belt conveyor 1 is hit by the rubber sleeve 45, which is safer.

[0053] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, a cleaning mechanism 5 is also included. The cleaning mechanism 5 is distributed at the bottom end of the belt conveyor 1, and the cleaning mechanism 5 includes: a No. 2 side plate 51, a bottom plate 52, a lifting plate 53, a brush 54 and a threaded screw 55. The two No. 2 side plates 51 are symmetrically fixed to the bottom end of the belt conveyor 1, the bottom plate 52 is fixed to the bottom end of the No. 2 side plate 51, the lifting plate 53 is located on the upper side of the bottom plate 52, the brush 54 is elastically connected to the lifting plate 53, the threaded screw 55 is installed on the bottom plate 52 by threaded engagement, and the top of the threaded screw 55 is rotatably connected to the lifting plate 53 by a bearing. After adopting the above scheme, when working, by rotating the threaded screw 55, the threaded screw 55 drives the lifting plate 53 to move under the action of threaded engagement, and the initial height of the brush 54 is adjusted so that the brush 54 contacts the belt of the belt conveyor 1. As the belt conveyor 1 runs, the brush 54 is used to clean the belt of the belt conveyor 1.

[0054] Optionally, by Figure 1 and Figure 4 As shown, in this embodiment, the cleaning mechanism 5 also includes: a threaded rod 57, a locking nut 58 and a telescopic spring 59. The threaded rod 57 is fixed to the bottom surface of the brush 54, and the threaded rod 57 passes through the lifting plate 53. The locking nut 58 is installed on the protruding end of the threaded rod 57 by threaded engagement. The telescopic spring 59 is sleeved on the threaded rod 57 and is located between the lifting plate 53 and the threaded rod 57, thereby realizing the elastic installation of the brush 54, ensuring that the brush 54 reliably contacts the belt of the belt conveyor 1, and improving safety.

[0055] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, the cleaning mechanism 5 further includes: a knob 551 , which is fixed to the bottom end of the threaded screw 55 , and the threaded screw 55 is easily rotated by the arrangement of the knob 551 .

[0056] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, the cleaning mechanism 5 also includes: guide columns 56, two guide columns 56 are symmetrically fixed to the bottom surface of the lifting plate 53, and the guide columns 56 pass through the bottom plate 52. After adopting the above scheme, the two guide columns 56 are used to guide the lifting plate 53, thereby improving the stability of the lifting plate 53.

[0057] It should be noted that the belt conveyor 1, the No. 1 drive motor 35 and the No. 2 drive motor 43 are all conventional commercially available equipment with built-in power switches. Those skilled in the art can make conventional selections according to usage requirements. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, and will not be elaborated in this article.

[0058] The circuit connection involved in the present invention is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments, and it belongs to the widely used existing technology.

[0059] Components not described in detail herein are prior art.

[0060] Working principle and use process of the present invention: When the magnetic separator of the present invention is used, the belt conveyor 1 is started and the electromagnet 2 is energized, and the No. 1 driving motor 35 is started to drive the rotating roller 34 to rotate, and the building material waste to be deironed is directly put into the upper hopper 33, or is put into the upper hopper 33 after being crushed;

[0061] The waste building materials pass through the gaps at the top of the upper hopper 33 and the quantitative hopper 32 and enter the quantitative slots 341. As the rotating roller 34 rotates, an equal amount of waste building materials is stored in each quantitative slot 341. When the quantitative slots 341 rotate to coincide with the discharge port 321, the waste building materials are discharged and fall onto the belt of the belt conveyor 1 for transportation. The waste building materials are transported by the belt conveyor 1, and the electromagnet 2 has magnetism after being energized, and can attract iron. The iron contained in the waste building materials will be adsorbed on the belt of the belt conveyor 1.

[0062] The magnetic separator of the present invention ensures that the waste building materials fall onto the belt of the belt conveyor 1 more evenly for transportation through quantitative feeding, thereby preventing the accumulation of waste building materials from affecting the adsorption of iron by the belt, and greatly improving the iron removal effect;

[0063] It should be noted that the cleaning mechanism 5 provided in the present invention can also scrape off the iron on the belt conveyor 1. A small amount of iron will still be adsorbed on the belt of the belt conveyor 1 due to the adsorption effect of the electromagnet 2. When the iron needs to be further cleaned later, the belt conveyor 1 is started and the electromagnet 2 is turned off at the same time. After the electromagnet 2 is powered off, it loses its magnetism and the iron will not be adsorbed, so it will fall out naturally under the action of its own gravity.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
