Description

Technical Field

[0001] The utility model relates to the technical field of scrap steel recovery equipment, and specifically discloses a scrap steel recovery and sorting device. Background Art

[0002] In the process of recycling scrap steel in items, a crusher is usually used to directly break the items into crushed materials. These crushed materials often contain materials of various materials, such as plastic, glass, crushed steel, etc., so they need to be sorted in the subsequent recycling process.

[0003] When recycling scrap steel from crushed materials, traditional scrap steel recycling stations first use a vibrating screen to remove small particles such as dust and broken plastic from the material, and then use a magnetic conveyor belt for magnetic separation. The entire scrap steel sorting process requires at least two sets of equipment, a vibrating screen and a magnetic conveyor belt, which not only causes the equipment of the entire sorting line to occupy a large area, but also uses a method of first vibrating screening and then magnetic screening, which will cause some small particles of steel fragments to be screened and removed, making it impossible to effectively recycle this part of the scrap steel, thereby causing material waste. Therefore, based on the above-mentioned deficiencies of the equipment used in the existing scrap steel recycling and sorting steps, the present application proposes a scrap steel recycling and sorting machine that can effectively solve this technical problem.

[0018] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0019] Example 1

[0020] Example 1 discloses a scrap steel recycling and sorting device, see the attached Figure 1-4 , its main part includes a sorting box 1 and a hopper 2. The hopper 2 is set at one end of the upper surface of the sorting box 1, so that the crushed material is poured from the hopper 2 into the inside of the sorting box 1. A downwardly inclined vibrating screen plate 3 is set in the sorting box 1 below the hopper 2. When specifically set, convex plates 104 are set on the front and rear inner walls of the sorting box 1, and then the front and rear side ends of the vibrating screen plate 3 are connected to the convex plates 104 through the first spring 105. At the same time, a corresponding vibration motor 301 is installed on the vibrating screen plate 3, so that the crushed material can slide downward and be screened and sorted under the high-frequency vibration of the vibrating screen plate 3.

[0021] A conveyor belt 4 is arranged in the sorting box 1 located above the vibrating screen plate 3, and one side of the lower end of the conveyor belt 4 is arranged parallel to the upper surface of the vibrating screen plate 3, and then a plurality of bar magnets 5 are arranged at equal intervals on the outer surface of the conveyor belt 4. In the specific arrangement, the cross section of the conveyor belt 4 is arranged in a triangular shape, and three belt rollers 401 acting on the conveyor belt 4 are arranged in rotation in the sorting box 1, and the end of one of the belt rollers 401 is connected to a first driving device 402, so that the conveyor belt 4 can be driven to move at a uniform speed and sequentially under the action of the first driving device 402. In addition, in order to ensure that the bar magnet 5 can have a good adsorption effect on the scrap steel on the upper surface of the vibrating screen plate 3, the distance between the side of the conveyor belt 4 parallel to the upper surface of the vibrating screen plate 3 and the vibrating screen plate 3 is set between 5-20cm.

[0022] A magnetic roller 6 is rotatably installed in the sorting box 1 on the side away from the hopper 2, and one end of the conveyor belt 4 is arranged close to the magnetic roller 6. At the same time, the magnetic attraction force of the magnetic roller 6 on the scrap steel is much greater than the magnetic attraction force of the bar magnet 5 on the scrap steel, so that when the bar magnet 5 carries the scrap steel and moves to a position close to the magnetic roller 6, the scrap steel can be transferred to the magnetic roller 6.

[0023] In addition, a shovel plate 7 is provided in the sorting box 1 and is fitted with the lower half of the magnetic roller 6. In the specific design, one end of the shovel plate 7 is rotatably connected to the rotating seat 701 on the inner end wall of the sorting box 1, and the other end is fitted with the lower half of the magnetic roller 6. Then, a second spring 702 is connected between the shovel plate 7 and the inner end wall of the sorting box 1. Through the action of the second spring 702, one end of the shovel plate 7 can be set tightly against the lower half of the magnetic roller 6, and then the shovel plate 7 can shovel all the scrap steel materials adsorbed on its surface off.

[0024] Finally, the lower part of the sorting box 1 is divided into a fine material collection area 101, a large material collection area 102 and a scrap steel collection area 103 by two partitions. The fine material collection area 101 is located below the vibrating screen plate 3, the scrap steel collection area 103 is located below the magnetic roller 6, and the large material collection area 102 is located between the fine material collection area 101 and the scrap steel collection area 103. Then, the first receiving trough 8, the second receiving trough 9 and the third receiving trough 10 are provided at the lower end of the front side of the sorting box 1, extending into the fine material collection area 101, the large material collection area 102 and the scrap steel collection area 103.

[0025] The specific operating principle and working steps of the scrap steel recovery and sorting device disclosed in this embodiment 1 are as follows:

[0026] During the unloading process of the hopper 2, the vibration motor 301 and the first driving device 402 are started synchronously, and the vibration screen plate 3 can vibrate at a high frequency under the action of the vibration motor 301, so that the crushed materials falling on the upper surface of the vibration screen plate 3 can slide down along the surface and be filtered. Under the action of the first driving device 402, the conveyor belt 4 is moved cyclically at a set speed, and the bar magnet 5 on the conveyor belt 4 is close to the upper surface of the vibration screen plate 3. The scrap steel in the crushed materials is adsorbed, thereby separating it from other crushed materials.

[0027] After separation, the small particles and dust in other broken materials fall into the scrap steel collection area 103 through the sieve holes on the vibrating screen plate 3 and are received by the first receiving trough 8. The unscreened large blocks slide down the upper surface of the vibrating screen plate 3 and fall into the large block collection area 102 and are received by the second receiving trough 9.

[0028] The scrap steel material attracted by the bar magnet 5 is transported and moved to the vicinity of the magnetic roller 6 along with the conveyor belt 4. Since the magnetic field of the magnetic roller 6 is greater than that of the bar magnet 5, the scrap steel material attracted by the bar magnet 5 is transferred to the outer surface of the magnetic roller 6. Then, during the rotation of the magnetic roller 6, the scrap steel material attracted and fixed on the roller body of the magnetic roller 6 is shoveled off by the shovel plate 7 and falls into the scrap steel collection area 103 to be received by the third receiving trough 10, thereby completing the sorting operation in the scrap steel recycling process.

[0029] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
