[0029] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those ordinarily skilled in the art without creative work fall within the scope of the present application.

[0030] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0031] Referring to FIG. 1, Figs. 1 to 3 The present embodiment provides a building waste crushing and sorting integrated equipment, mainly comprising a support 1, a crushing part 2, a screening part, a conveying part 4 and a magnetic separation part. The crushing part 2 is fixedly connected to the top of one side of the support 1, that is, among the functional parts, the crushing part 2 is located at the uppermost position. The screening part is also fixedly connected to the support 1 and located below the crushing part 2 and corresponds to the outlet of the crushing part 2, which receives the crushed materials from the crushing part 2. The conveying part 4 is arranged at the bottom of the support 1, that is, among the functional parts, the conveying part 4 is located at the lowermost position, and the feeding end of the conveying part 4 is located below the screening part to receive the qualified particle size materials obtained by the screening part. The magnetic separation part is fixedly connected to the support 1 and located above the conveying part 4, mainly comprising a belt conveyor 51, the belt conveyor 51 is arranged vertically to the conveying part 4, the starting end of the belt conveyor 51 is provided with an electromagnet 52 and located above the conveying part 4, the end of the belt conveyor 51 extends out of the conveying part 4, and a receiving box 6 is placed below the end.

[0032] In the utility model, the support 1 is fixedly connected with the crushing part 2, the screening part, the conveying part 4 and the magnetic separation part to form an integrated equipment, so that the structure is more compact, the material transfer process is reduced, and the processing efficiency is improved. The crushing part 2 can crush the bulky construction waste, and simultaneously preliminarily separate the mixed steel bars and other iron products from cement and lime, so that subsequent sorting is facilitated. The screening part can screen the crushed construction waste, the oversize material is discharged and can continue to circulate into the crushing part 2 for secondary crushing until the size is qualified, and the undersize material falls onto the conveying part 4 and is transported outward. The conveying part 4 can uniformly and flatly transport the construction waste with a suitable size crushed to below the magnetic separation part, so that the construction waste is prevented from piling up, and the magnetic separation part is facilitated to perform magnetic separation. For example, the conveying part 4 can adopt a common type of belt conveyor such as a DTL fixed landing belt conveyor and a TD75 belt conveyor. The electromagnet 52 in the magnetic separation part is powered on, and the magnetic force thereof can suck the iron product from the conveying part 4 through the conveyor belt below the belt conveyor 51, the iron product is abutted against the conveyor belt below the belt conveyor 51 and moves along the conveyor belt to the outside of the conveying part 4 until the iron product is moved out of the conveying part 4, at this time, the iron product also gradually separates from the magnetic force range of the electromagnet 52 and gradually falls into the receiving box 6 below, and the magnetic separation of the iron product in the construction waste is completed.

[0033] According to the above process, it is obvious that the magnetic separation part in the utility model does not need to turn on and off the electromagnet 52 to realize the suction and release of the iron product, and can continuously perform magnetic separation on the construction waste conveyed on the conveyor belt following the rhythm of crushing, screening and conveying, so that the efficiency of crushing and sorting of the construction waste is greatly improved.

[0034] Further optimization scheme, the crushing part 2 is a jaw crusher.

[0035] The jaw crusher can produce strong crushing force by extrusion of the movable jaw plate and the fixed jaw plate, has good adaptability to various materials, is not afraid of property changes, and has strong wear resistance; the construction waste is mostly bulky and hard material, and has different composition and hardness; therefore, according to the properties and working conditions of the construction waste, the jaw crusher is an ideal choice.

[0036] Further optimization scheme, the screening part includes a vibrating screen 31, the vibrating screen 31 is fixedly installed on the support 1 below the crushing part 2, the vibrating screen 31 is obliquely arranged, the lower end of the vibrating screen 31 extends out of the support 1, and a vibrating motor is fixedly connected to the bottom of the vibrating screen 31.

[0037] The vibrating screen 31 receives the construction waste particles crushed by the crushing part 2, the vibrating screen 31 is obliquely arranged and the lower end thereof extends out of the support 1, so that the oversize material can roll to the outside of the support 1 and can be mixed with the construction waste to be crushed and then enter the crushing part 2 again.

[0038] Further optimization scheme, the support 1 corresponding to the position below the vibrating screen 31 is fixedly connected with a conveying plate 32, the conveying plate 32 is inclinedly arranged, the higher end of the conveying plate 32 receives the undersize of the vibrating screen 31, and the lower end is smoothly connected with the feeding end of the conveying part 4.

[0039] The conveying plate 32 directly receives the undersize of the vibrating screen 31, and slowly slides the undersize to the conveying part 4 through the slope of the conveying plate 32, avoiding that the conveying part 4 directly receives the undersize of the vibrating screen 31, so that the conveying part 4 is damaged.

[0040] Further optimization scheme, the belt conveyor 51 and the electromagnet 52 are hung on the support 1 through the connecting frame 53.

[0041] The belt conveyor 51 and the electromagnet 52 are hung on the support 1, so that the number of supporting legs at the bottom of the equipment can be reduced, personnel or vehicles can be moved conveniently, and the magnetic separation process of the undersize can be observed conveniently.

[0042] Further optimization scheme, the electromagnet 52 is close to the inner plane of the conveying belt below the belt conveyor 51. It is easy to understand that “close” here does not mean “attached contact” only, but means that the distance between the two is small, so that the magnetic force can be maximized. When the iron content is high, the conveying belt may be in contact with the electromagnet 52 under the action of magnetic force, so the upper and lower surfaces of the electromagnet 52 should be smooth, and the electromagnet 52 can be further processed into a cylindrical shape (axial horizontal, and perpendicular to the conveying direction of the belt conveyor 51), or a plurality of cylindrical shapes are connected in parallel in the form of “conveying rollers”, so that the conveying force is much larger than the magnetic force.

[0043] The electromagnet 52 is close to the inner plane of the conveying belt below, the magnetic force is stronger, and the conveying belt can be supported to some extent to help resist the impact when iron products are attracted.

[0044] Further optimization scheme, the outer side of the conveying belt at the end of the belt conveyor 51 is abutted with a scraper 54, and the scraper 54 is fixedly connected to the connecting frame 53. Here, “outer side” refers to the end of the conveying direction, as shown in Fig. 3 .

[0045] The scraper 54 can scrape off the iron products such as iron debris that are easily adhered to the conveying belt, so as to avoid the iron products entering the next magnetic separation cycle with the conveying belt. The distance between the scraper 54 and the outer side of the conveying belt can be adjusted according to the processing object, so as to achieve good scraping effect and prevent damage to the conveying belt during scraping.

[0046] Further optimization scheme, a feeding machine 7 is arranged outside the feeding port of the crushing part 2.

[0047] The feeding machine 7 can realize uniform feeding of the crushing part 2.
