Description

Technical Field

[0001] The invention relates to the technical field of steel processing waste recycling systems, and in particular to a processing waste steel grading system. Background Art

[0002] After cutting and welding of steel, scraps of different sizes will be generated. These scraps need to be recycled to avoid wasting iron resources and causing adverse effects on the surrounding environment (if the smallest iron filings are not processed, they will cause damage to the environment). In the existing technology, the scraps are directly collected and packaged and sent to the next step for processing. During this process, large and small scrap steels are mixed together and need to be classified again before the next step of processing. In addition, during transportation, some small scrap steels are easy to fall, causing waste and environmental damage. Summary of the invention

[0003] In view of the shortcomings of the prior art, the invention provides a scrap steel grading system, which solves the problem in the prior art that the packaged scrap steel needs to be graded again before further processing, and small particles of scrap steel are easily dropped during transportation, causing waste and environmental damage.

[0004] According to an embodiment of the invention, a system for grading scrap steel includes a base and a grading box elastically mounted on the base, a feed hopper is mounted on the upper end of the grading box, a first grading component, a second grading component and a third grading component are elastically mounted in the grading box from top to bottom, the scrap steel enters the grading box from the feed hopper and is graded by the first grading component to produce a first oversize, the scrap steel is graded by the second grading component to produce a second oversize, and the scrap steel is graded by the third grading component to produce a third oversize; and the system also includes three collecting components inserted from outside the grading box into the grading box for collecting the first oversize, the second oversize and the third oversize, respectively.

[0005] In the above technical scheme, scrap steel of mixed sizes is fed into the system from the feed hopper, and after being graded by the first to third grading components, the first oversize material, the second oversize material and the third oversize material are formed respectively, and then three magnetic plates are used to collect the first oversize material, the second oversize material and the third oversize material respectively, and then they can be graded and packaged.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The system first grades the mixed scrap steel step by step, and then uses multiple collection components to collect the graded screen material. After collection, it is graded and packaged in a targeted manner. There is no need to grade the packaged scrap steel again when further processing it. In addition, during transportation, the graded and packaged scrap steel is processed in a targeted manner, so there will be no falling due to mixed loading. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0014] like Figures 1 to 4 As shown, this embodiment provides a scrap steel grading system, which includes a base 1, and a grading box 2 elastically mounted on the base 1, a feeding hopper 3 for the scrap steel to enter the grading box 2 is installed on the upper end of the grading box 2, and a first grading component, a second grading component and a third grading component are elastically mounted from top to bottom in the grading box 2, and they all include a plurality of first mounting seats 4 fixedly mounted on the inner wall of the grading box 2 and a support frame 5 elastically connected to the corresponding first mounting seats 4, wherein:

[0015] The inner frame wall of the support frame 5 of the first grading component is connected with a first screen 6, the inner frame wall of the support frame 5 of the second grading component is connected with a second screen 7, and the inner frame wall of the support frame 5 of the third grading component is connected with a third screen 8, and the mesh of the first screen 6 is larger than the mesh of the second screen 7, and the mesh of the second screen 7 is larger than the mesh of the third screen 8;

[0016] After the scrap steel enters the grading box 2 from the feed hopper 3, it is graded by the first grading assembly to produce the first screen material with the largest size, graded by the second grading assembly to produce the second screen material with a larger size, and graded by the third grading assembly to produce the third screen material with a smaller size;

[0017] In order to collect the classified scrap steel, the system further includes three collecting assemblies inserted from outside the classification box 2 into the classification box for collecting the first oversize, the second oversize and the third oversize respectively.

[0018] In particular, in order to effectively collect the undersize of the third grading assembly of the smallest size, the system further comprises a magnetic collecting plate 9 which is inserted into the grading box 2 from outside and is located below the third grading assembly.

[0019] In the above embodiment, scrap steel of mixed sizes is fed into the system from the feed hopper 3, and is graded by the first to third grading components to form the first oversize, the second oversize and the third oversize respectively. Then, three collecting components are used to collect the first oversize, the second oversize and the third oversize respectively, and at the same time, a magnetic collecting plate 9 is used to collect the scrap steel of the smallest size, which can then be graded and packaged.

[0020] Preferably, the first mounting seat 4 is respectively located on the upper and lower sides of the corresponding support frame 5, and a first spring 10 is also fixedly connected between the first mounting seat 4 and the support frame 5. In order to achieve stable elastic support for the support frame 5 and the screen thereon, the first mounting seat 4 is respectively arranged on the three inner walls of the grading box 2, and the fourth inner wall is used to install the collection component.

[0021] Preferably, the collecting assembly includes a magnetic plate 11 inserted from outside the grading box 2, and one side of the magnetic plate 11 is placed on the corresponding support frame 5, and a smooth transition is made between the support frame 5 and the magnetic plate 11, so as to achieve magnetic adsorption of the screened material during vibration. In particular, a space for the magnetic plate 11 to be inserted and pulled out is provided on the grading box 2, and a protective plate 12 covering the space and located outside the grading box 2 is fixedly connected to the magnetic plate 11;

[0022] In order to ensure that the magnetic plate 11 vibrates synchronously with the corresponding grading assembly, three second mounting seats 13 located above each magnetic plate 11 are fixedly installed on the inner wall of the grading box 2, and the second mounting seats 13 are fixedly connected to the second springs 14, which extend downward and are fixedly connected to the upper top plate 15 that rests on the corresponding magnetic plate 11.

[0023] Preferably, in order to collect the non-ferrous impurities screened out by each grading component, the collecting component also includes three collecting boxes 16 located below each of the magnetic plates 11, and the collecting boxes 16 are fixedly mounted on the inner wall of the grading box 2, and the collecting boxes 16 are provided with an opening located directly below the corresponding magnetic plate 11, and the collecting box 16 is also fixedly connected to the collecting box 16, and the third spring 17 is extended upward and fixedly connected to a lower top plate 18 resting on the corresponding magnetic plate 11, wherein the upper top plate 15 and the lower top plate 18 jointly realize stable elastic support for the magnetic plate 11, in particular, in the initial state, the upper top plate 15 and the lower top plate 18 are only in contact with the magnetic plate 11, and there is no interaction force, which can ensure that the non-magnetic blocks can also be normally pulled out and inserted.

[0024] Preferably, a fourth spring 19 is also fixedly connected to the collection box 16, and the fourth spring 19 is fixedly connected to the corresponding support frame 5 after extending upward. The support frame 5 is also fixedly connected to a baffle 20 that is inserted downward into the corresponding opening. The setting of the fourth spring 19 allows the side of the support frame 5 close to the magnetic plate 11 to be elastically supported, thereby improving its vibration stability. The setting of the baffle 20 can prevent non-ferrous impurities from escaping from the corresponding collection box 16.

[0025] Preferably, the grading box 2 is hingedly provided with a first opening and closing door 21 for opening and closing each of the collecting boxes 16 , so that the non-ferrous impurities can be collected through the first opening and closing door 21 .

[0026] Preferably, in order to realize the up and down vibration of the grading box 2, a plurality of first vertical through holes 22 are provided on the base 1, and a telescopic rod 23 extending upward is provided in each first vertical through hole 22, and the upper end of the telescopic rod 23 is fixedly connected to the grading box 2, and each telescopic rod 23 is also wound with a fifth spring 24, the upper end of which is fixedly connected to the grading box 2 and the lower end of which is fixedly connected to the base 1. Such a setting can ensure the normal up and down vibration of the grading box 2.

[0027] Preferably, the base 1 is also provided with a second vertical through hole 25 located in the center, and a vibration motor 26 fixedly installed on the bottom of the grading box 2 is provided above the second vertical through hole 25. The vibration motor 26 can drive the grading box 2 and the components therein to vibrate up and down when running, and the setting of the second vertical through hole 25 can ensure that the vibration motor 26 will not be hit by the base 1.

[0028] When the system provided in this embodiment is running:

[0029] First, a non-magnetic block of the same size as the magnetic plate 11 is inserted to cover the position directly above each collection box 16, and then the scrap steel to be graded is put into the feed hopper 3, and the vibration motor 26 is started. After the grading operation is completed, the vibration motor 26 is stopped, the non-magnetic block is taken out, and the magnetic plate 11 is reinserted and the vibration motor 26 is started again to collect the screened material. After the screened material is collected and accepted, the vibration motor 26 is stopped, the magnetic plate 11 is taken out to collect and pack the adsorbed material thereon, and after taking it out, the vibration motor 26 is started again to recover the non-ferrous impurities, and finally the magnetic disk is taken out and the non-ferrous impurities therein are poured out (due to magnetic adsorption, the ferrous impurities will not fall off), and then the ferrous impurities adsorbed thereon are packaged.

[0030] The system provided in this embodiment first grades the mixed scrap steel step by step, and then uses a plurality of magnetic plates 11 to collect the graded material on the screen, and uses a magnetic collection plate 9 to collect the final material under the screen. After collection, targeted graded and packaged materials are performed, and there is no need to grade the packaged scrap steel again when further processing is performed. In addition, during transportation, the graded and packaged materials are processed in a targeted manner, so there will be no falling caused by mixed loading.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
