Description

Technical Field

[0001] The utility model relates to the technical field of steel shot screening, in particular to a steel shot screening device. Background Technique

[0002] Steel shot is a commonly used metal workpiece processing material. The steel shot has a dense structure and uniform particle size. Treating the surface of metal workpieces with steel shot can increase the surface pressure of the metal workpieces and improve the anti-fatigue performance of the workpieces. Treating the surface of metal workpieces with steel shot has the characteristics of fast cleaning speed. The steel shot and steel grit have moderate hardness and good resilience performance. The inner corners and complex workpieces can be cleaned evenly and quickly, shortening the surface treatment time and improving the work efficiency. Therefore, it is a very good surface treatment material.

[0003] After the steel shot is used for a period of time, it is necessary to screen the steel shot, select the qualified steel shot, and recycle the unqualified steel shot and steel ash. At present, some factories need to manually screen the steel shot with the help of a sieve, which is inconvenient to operate, has low screening efficiency, and serious environmental pollution during screening; in addition, there are also some steel shot screening devices, such as a Chinese utility model patent with the patent number CN202020095816.8 and the patent name of a steel shot rough screening device, which includes a stirring cylinder, a steel shot adding port is installed on the left side of the end of the stirring cylinder, a driving motor is installed on the left side of the stirring cylinder, a base is arranged at the bottom of the driving motor, the driving end of the driving motor penetrates through the left side wall of the stirring cylinder and extends into the interior of the stirring cylinder to be connected with a stirrer, a waste collection box is installed at the bottom of the stirring cylinder, a first filter screen is installed on the left side of the end of the waste collection box and below the stirrer, a steel shot discharge port is installed on the right side of the stirring cylinder, a second filter screen is installed on the right side of the end of the waste collection box and below the steel shot discharge port, and a cover plate is installed on the front of the waste collection box through bolts. Although the above device can realize the screening of steel shot, it needs to rely on the driving motor to drive the spiral stirrer, and the spiral stirrer drives the steel shot to move and screen in the stirring cylinder. Since it is necessary to drive the steel shot to move through the spiral stirrer, the screening efficiency is relatively low, and if too many steel shots are put in at one time, it is easy to get stuck on the filter screen, resulting in blockage and affecting the screening quality.

[0031] Combined Figures 1 - 5 As shown, a steel shot screening device includes a frame 1. A multi-layer vibrating screen assembly 2 is inclined and connected to the frame 1. There are several tension springs 3 between the multi-layer vibrating screen assembly 2 and the frame 1. Specifically, the tension springs 3 are arranged on both sides of the multi-layer vibrating screen assembly 2, and the ends far from the multi-layer vibrating screen assembly 2 are fixedly connected to the frame 1. The top of the inclined multi-layer vibrating screen assembly 2 is connected to a lifting conveyor mechanism 4. The end of the lifting conveyor mechanism 4 far from the multi-layer vibrating screen assembly 2 is arranged in a mixed steel shot filling box 5. A waste collection hopper 6 abuts against the bottom of the multi-layer vibrating screen assembly 2. In this embodiment, the waste collection hopper 6 is fixed to the frame 1 through a support rod. The bottom of the waste collection hopper 6 is communicated with a waste box 7. The bottom of the inclined multi-layer vibrating screen assembly 2 is connected to a separation box 8. The separation box 8 is connected to a separation and collection box 9. Thus, the mixed steel shots in the mixed steel shot filling box 5 can be gradually conveyed to the multi-layer vibrating screen assembly 2 through the lifting conveyor mechanism 4. The inclined multi-layer vibrating screen assembly 2 can perform multi-level screening on the mixed steel shots, and the steel shots screened at different levels are respectively conveyed to different separation and collection boxes 9 through the separation box 8. At the same time, by using the vibration method for screening and cooperating with the sequential feeding of the lifting conveyor mechanism 4, the steel shots are not easily blocked in the mesh holes of the screen 203. By arranging the tension springs 3 between the multi-layer vibrating screen assembly 2 and the frame 1, elastic connection between the multi-layer vibrating screen assembly 2 and the frame 1 is achieved through the tension springs 3, which facilitates the vibration of the multi-layer vibrating screen assembly 2. By setting the waste box 7, the unqualified steel shots and steel ash after screening by the multi-layer vibrating screen assembly 2 can be recycled.

[0032] Combined with Figures 1 - 5 As shown, the multi-layer vibrating screen assembly 2 includes two baffles 201 arranged oppositely. The two baffles 201 are respectively connected to the frame 1 through a plurality of tension springs 3. Vibrators 202 are installed on both sides of the two baffles 201. The multi-layer vibrating screen assembly 2 can be driven to vibrate through the vibrators 202. A plurality of screen meshes 203 are arranged vertically between the two baffles 201. The screen mesh 203 arranged at the top of the baffle 201 is connected to the lifting conveyor mechanism 4. The bottom of the screen mesh 203 is connected to the separation box 8. By arranging a plurality of screen meshes 203 vertically, the plurality of screen meshes 203 can perform hierarchical screening on the steel shots. According to the different pore diameters of the screen meshes 203, the steel shots are divided into different diameters. In this embodiment, three layers of screen meshes 203 are provided, and the steel shots can be screened into three levels: large, medium, and small by the three layers of screen meshes 203;

[0033] In addition, an elastic material receiving plate is provided between the screen mesh 203 arranged at the top of the baffle 201 and the lifting conveyor mechanism 4.

Curtains 11 are respectively connected to the two ends of the dust covers 10 close to the lifting conveyor mechanism 4 and the separation box 8. Through the dust covers 10 and the curtains 11, when the multi-layer vibrating screen assembly 2 performs vibrating screening on the steel shots, steel dust is prevented from escaping due to vibration, thus affecting the working environment.

[0036] Combined with Figures 1 - 5As shown in the figure, the separation box 8 includes a box body 801. A number of separation plates 802 are arranged vertically on the box body 801. The number of separation plates 802 divides the inner cavity of the box body 801 into a number of separation chambers 803. One end of each of the number of separation chambers 803 close to the multi-layer vibrating screen assembly 2 is provided with a feed port 804. The feed port 804 is arranged corresponding to the screen mesh 203. Each separation chamber 803 is also communicated with a discharge chute 805. The discharge chutes 805 are respectively connected to the separation and collection box 9. By arranging a number of separation plates 802, the box body 801 can be divided into a number of separation chambers 803. Different separation chambers 803 are communicated with different screen meshes 203 through the feed ports 804, so that the steel balls screened by different screen meshes 203 can be transported into different separation and collection boxes 9 through the separation chambers 803 and the discharge chutes 805, thereby realizing the screening and separation of the steel balls.

[0037] Combined with Figures 1 - 5 As shown in the figure, the discharge chutes 805 are respectively arranged on different sides of the box body 801. By arranging the discharge chutes 805 on different sides of the box body 801 respectively, it is convenient to transport steel balls of different diameters to different positions respectively, which is convenient for the staff to identify and handle.

[0038] Combined with Figures 1 - 3 As shown in the figure, the lifting conveyor mechanism 4 includes a lifting frame 401. The mixed steel ball filling box 5 is arranged at the bottom of the lifting frame 401. The top and bottom of the lifting frame 401 are respectively rotatably installed with transmission rollers 402 through bearing seats.

By driving the transmission roller 402 to rotate by the driving motor 403, the transmission roller 402 drives the lifting belt 404 to synchronously drive during the rotation process. Since the lifting buckets 405 are arranged on the lifting belt 404, the lifting buckets 405 are driven to synchronously drive, and then the mixed steel balls in the mixed steel ball filling box 5 are transported to the inclined top of the multi-layer vibrating screen assembly 2, thereby realizing the automatic feeding of the steel balls.

[0039] For the convenience of understanding, the working process of this embodiment is given below:

[0040] Combined with Figures 1 - 5As shown in the figure, first, pour the mixed steel shots into the mixed steel shot filling box 5. Then, start the vibrator 202.

The drive motor 403 drives the transmission roller 402 to rotate. The transmission roller 402 drives the lifting belt 404 to synchronously drive. The lifting belt 404 drives the lifting bucket 405 to convey the mixed steel shots in the mixed steel shot filling box 5 to the top of the inclined multi-layer vibrating screen assembly 2. Then, pour the mixed steel shots in the lifting bucket 405 onto the multi-layer vibrating screen assembly 2.
