Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a slag and shot magnetic separation device for shot blasting machines. Background Art

[0002] Traditional shot blasting machine separation devices often use simple screening or air separation methods. These methods have disadvantages such as low separation efficiency, easy clogging, and high maintenance costs. They are particularly ineffective when processing shot materials containing large amounts of complex impurities such as sticky sand and burrs. For example, in the precision casting industry such as water glass, casting, or silica sol, due to the high hardness of sticky sand and the easy wear of equipment, traditional separation methods are often unable to effectively separate the metal shot, resulting in high wear and tear of shot blasting machine parts and a short service life.

[0003] The reference patent name is a shot blasting waste recycling system (publication number CN205588159U), wherein the shot blasting waste recycling system includes a shot sand separator, a vibrating screening device and a magnetic separation device arranged in sequence, the shot sand separator is used to separate the shot material containing projectiles from the shot blasting waste, the vibrating screening device is used to screen the shot material into the projectiles and iron-containing ash, and the magnetic separation device is used to sort out iron powder from the iron-containing ash. The use of triple sorting can effectively recover the beneficial resources in the shot blasting waste: first, the shot sand in the shot blasting waste is initially separated by the shot blasting separator; then, the projectiles in the shot material are separated by the vibrating screening device; finally, the iron-containing resources in the undersize of the shot material are separated by the magnetic separation device, thereby maximizing the recovery of the beneficial resources in the shot blasting waste.

[0004] In the above patent, metal materials are screened out by a magnetic separation device. However, during the magnetic separation process, since the slag and shot magnetic separation materials are of different sizes, different sizes of materials are suitable for different magnetic fields, resulting in insufficient magnetic separation during specific application. For this reason, the utility model provides a slag and shot magnetic separation device for a shot blasting machine. Utility Model Content

[0025] In this embodiment, the driving assembly 22 includes a mounting plate 221 fixedly mounted on the outer wall of one side of the bracket 3, a first transmission wheel 222 is rotatably mounted on the lower end of the mounting plate 221, and a second transmission wheel 224 is rotatably mounted on the upper end of the mounting plate 221, a motor 223 is fixedly mounted on the front end of the mounting plate 221, a power output end of the motor 223 is connected to the power input end of the first transmission wheel 222, a transmission belt 225 is connected between the first transmission wheel 222 and the second transmission wheel 224, a reciprocating rod 226 is fixed to one end of the second transmission wheel 224, and a movable block 227 is rotatably connected to the other end of the reciprocating rod 226, and the movable block 227 is fixedly connected to the outer wall of one side of the screening box 212; the motor 223 is the first transmission wheel 222 outputs power, thereby driving the first transmission wheel 222 to rotate. The first transmission wheel 222 and the second transmission wheel 224 are connected by a transmission belt 225. When the first transmission wheel 222 rotates, the second transmission wheel 224 is driven to rotate synchronously by the transmission belt 225. A reciprocating rod 226 is fixed to one end of the second transmission wheel 224 (the reciprocating rod 226 is formed by two sections of rods movably connected), and the other end of the movable rod is rotatably connected to the movable block 227, and the movable block 227 is fixedly connected to one side outer wall of the screening box 212.

[0027] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] When working, first of all, the device is mainly composed of a material receiving box 1, a mobile screening mechanism 2 and a magnetic separation mechanism. The material receiving box 1 is used to carry the slag-shot mixture to be separated and is firmly supported by the bracket 3 at its lower end. At the upper end of the material receiving box 1, a mobile screening mechanism 2 is provided. The core of the mechanism lies in the coordinated work of the screening component 21 and the driving component 22. The screening component 21 includes two sets of track rods 211 and a screening box 212 slidably mounted thereon. The front and rear outer walls of the screening box 212 are provided with T-shaped sliders 213. These sliders can be horizontally moved along the preset track grooves on the track rods 211. The first and second transmission wheels 224 are connected to each other through a transmission belt 225. When the first and second transmission wheels 222 are rotated, the first and second transmission wheels 224 are rotated and mounted on the mounting plate 221. The first and second transmission wheels 222 are connected to each other through a transmission belt 225. When the first and second transmission wheels 222 are rotated, the first and second transmission wheels 224 are rotated and mounted on the mounting plate 221. When the first and second transmission wheels 222 are rotated, the first and second transmission wheels 224 are rotated and mounted on the mounting plate 221. When the first transmission wheel 222 rotates, the second transmission wheel 224 is driven to rotate synchronously through the transmission belt 225. A reciprocating rod 226 is fixed to one end of the second transmission wheel 224, and the other end of the movable rod is rotatably connected to the movable block 227. The movable block 227 is fixedly connected to the outer wall of one side of the screening box 212. Therefore, when the second transmission wheel 224 rotates, the reciprocating rod 226 and the movable block 227 are driven to make the screening box 212 reciprocate horizontally above the receiving box 1. This movement mode helps the slag and shot mixture to be fully mixed in the screening box 212. Screening separates particles of different particle sizes or densities. The slag-shot mixture after screening and magnetic separation is discharged into the magnetic separation chamber through the discharge nozzle 8 at the lower end of the material receiving box 1; in the magnetic separation mechanism, the rotating shaft 4 is rotatably installed on the inner wall of the bracket 3, on which the magnetic separation cylinder 5 is fixed. When the motor 223 is working, its power not only drives the screening box 212 to move through the transmission belt 225, but also drives the rotating shaft 4 and the magnetic separation cylinder 5 to rotate through the vertical meshing connection of the first bevel gear 6 and the second bevel gear 7. The magnetic separation cylinder 5 uses its magnetic attraction to separate ferromagnetic impurities in the slag-shot mixture, such as iron filings.

[0029] In summary, the present invention achieves efficient and accurate separation of slag shots for shot blasting machines by combining the screening effect of the mobile screening mechanism 2 with the magnetic separation effect of the magnetic separation mechanism, thereby improving production efficiency and product quality.
