Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal processing waste chip breaking treatment, and particularly relates to a pre-screening device for metal processing waste chips before breaking treatment. BACKGROUND

[0002] Metal processing waste chips are various in types and forms, mainly including iron chips, copper chips, aluminum chips, titanium chips and the like, and are corner scraps and chips generated in the metal processing process and are a type of waste metal. If the waste chips are not treated in time, a large amount of space will be occupied and the environment will be polluted. Therefore, the waste chips are currently recycled and treated to improve resource utilization. In the mechanical processing process, according to different processing types such as turning, milling and drilling, the specifications of the generated waste chips are inconsistent, and the waste chips need to be treated to the same specification (particle) size before being subjected to operations such as remelting.

[0003] The waste chips are usually broken by a metal crusher as shown in Figure 1 During operation, the waste chips accumulated on the ground are separated into small groups by hand and then transferred to the feed inlet of the crusher, broken by the breaking tool in the crusher and discharged through the lower discharge port. In this treatment process, the waste chips are usually in a winding state, so that the small groups of waste chips are difficult to separate, and after separation, the small groups of waste chips need to be manually lifted and added to the feed inlet of the crusher using a tool, which causes continuous physical burden in operation; and before breaking, the specifications of the waste chips generated by different processing types are inconsistent, so that the larger specification needs to be put into the crusher for breaking, and the waste chips of the same size after breaking will be brought into the crusher for breaking together with the larger specification waste chips, causing unnecessary increase of energy consumption of the crusher (the overall waste chip treatment amount is increased by the small specification waste chips and the large specification waste chips, and the small waste chips do not need to be broken). SUMMARY

[0004] In view of the above problems, the present application aims to provide a pre-screening device for metal processing waste chips before breaking treatment, which can mechanically realize the transfer operation of the waste chips, greatly reducing the continuous physical burden problem in the current manual transfer process of the waste chips. At the same time, the small particle waste chips are separated in advance, so that the small particle waste chips do not enter the crusher for breaking, thereby reducing the volume of the waste chips entering the crusher for breaking, speeding up the processing efficiency of the waste chips and reducing the power consumption and the excessive wear of the breaking tool.

[0005] In order to achieve the above object, the technical scheme adopted by the present application is as follows: A pre-screening device for metal processing waste chips before crushing treatment, which is connected between the ground-accumulated treatment waste chips and the feeding port of a crusher, and conveys the ground treatment waste chips to the feeding port, and further comprises a screening mechanism for pre-screening the waste chips in the conveying process.

[0006] Preferably, the pre-screening device is a conveying belt connected between the treatment waste chips and the feeding port, and the conveying belt is of a mesh structure.

[0007] Preferably, the crusher has a driving motor, and the screening mechanism comprises a screening wheel connected to the driving motor, the screening wheel is provided with a convex part on the side periphery at an interval for lifting the conveying belt, and the conveying belt is not in contact with two adjacent convex parts at the same time.

[0008] Preferably, a collecting frame is arranged between the screening wheel and the treatment waste chips, and the collecting frame is hingedly arranged on the ground.

[0009] The beneficial effects of the present application are as follows: the pre-screening device is connected between the ground-accumulated treatment waste chips and the feeding port of the crusher, and can continuously convey the ground treatment waste chips to the feeding port, thereby mechanically realizing the transfer operation of the waste chips, and greatly reducing the continuous physical burden problem existing in the current manual transfer of waste chips.

[0010] And the small-particle waste chips mixed in the waste chips needing to be crushed in the conveying process are pre-separated by the screening mechanism, so that the small-particle waste chips do not enter the crusher for crushing, thereby reducing the volume of the waste chips entering the crusher for crushing, speeding up the processing efficiency of the waste chips, and reducing the power consumption and the excessive wear of the crushing cutter.

[0022] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] See attached document Figures 1-10 The device shown is a pre-screening device for metal processing waste before crushing, such as... Figure 5 As shown, the pre-screening device is connected between the processing waste piled on the ground and the feed inlet 1a of the crusher 1, and transports the processing waste from the ground to the feed inlet 1a, thereby mechanically realizing the transfer of waste and greatly reducing the continuous physical burden in the current manual transfer of waste.

[0024] To reduce the processing time and power consumption of the crusher, smaller-sized waste chips need to be pre-separated to reduce the overall volume of waste chips processed. This shortens the processing time, reduces power consumption, and minimizes premature wear on the crusher's internal blades. Therefore, if... Figure 7 As shown, the pre-screening device also includes a screening mechanism for pre-screening the waste debris during the conveying process. This screening mechanism pre-separates small particles of waste debris mixed in with the waste debris that needs to be crushed during transportation, preventing these small particles from entering the crusher for crushing, thereby reducing the volume of waste debris entering the crusher and accelerating the waste debris processing efficiency.

[0025] Specifically, such as Figure 3 , 5As shown, the pre-screening device is a conveyor belt 2 connected between the waste debris handling and the feed inlet 1a, which is continuously rotating during conveying, so that after one end of the conveyor belt 2 is connected with the ground where the waste debris to be handled is accumulated, the operator uses a tool to continuously convey the waste debris to the bottom end of the conveyor belt 2, and the waste debris is continuously conveyed to the feed inlet 1a of the crusher by the driving of the conveyor belt 2 and enters the crusher for crushing. Compared with the current manual operation which needs to separate the small groups of waste debris completely, this way does not need to separate the waste debris, such as Figure 5 As shown, the waste debris can be continuously conveyed by the conveyor belt 2, thereby effectively solving the physical burden during manual operation.

[0026] In order to screen the waste debris during conveying, as shown, Figure 4 The conveyor belt 2 is a mesh structure. Under the action of the continuous rotation of the conveyor belt 2, the small-particle waste debris (the waste debris is usually in a loose structure) falls to the surface of the conveyor belt 2 and falls through the mesh holes of the surface to the ground to be accumulated, so that the waste debris entering the crusher is large-size waste debris that needs to be crushed and handled, which can effectively reduce the handling volume of the waste debris.

[0027] Further, in order to realize the pre-screening of the waste debris, as shown, Figures 6-7 The crusher has a driving motor 3, and the screening mechanism includes a screening wheel 4 connected to the driving motor 3, which is provided with a protruding part 41 on the side periphery to lift the conveyor belt 2. During the rotation of the screening wheel 4 driven by the driving motor 3, the protruding part 41 acts on the conveyor belt 2, and at the same time cooperates with the rotating force of the conveyor belt 2 to make the conveyor belt 2 generate a certain vibration effect, thereby accelerating the separation and falling of the small-particle waste debris and the large-particle waste debris.

[0028] In order to further improve the vibration effect of the conveyor belt 2, as shown, Figure 7 That is, the conveyor belt 2 only contacts one of the protruding parts 41 during rotation, but does not contact two protruding parts 41 at the same time. Its function is that between the contact of the conveyor belt 2 with the current protruding part 41 and the contact with the next adjacent protruding part 41 after disengagement, the conveyor belt 2 will not contact any protruding part 41 intermittently. After the conveyor belt 2 contacts the protruding part 41, the protruding part 41 will lift the conveyor belt 2 to a certain height, so that when the conveyor belt 2 does not contact the protruding part 41, the conveyor belt 2 will fall, and after falling, it will immediately contact the next rotating protruding part 41, thereby lifting the conveyor belt 2 again. The reciprocating up and down can effectively increase the vibration effect of the conveyor belt 2, thereby accelerating the complete separation of the small-particle waste debris and the large-size waste debris, and further improving the screening effect.

[0029] In order to collect the small-particle waste debris pre-screened, as shown, Figure 8As shown, a collecting frame 5 is arranged between the screening wheel 4 and the processed waste chips, and the collecting frame 5 is hingedly arranged on the ground. The collecting state is as shown in Figure 9 As shown, the falling small-particle waste chips are accumulated in the collecting frame 5; and after a large amount of accumulation, the collecting frame 5 is driven to overturn, and the collected small-particle waste chips are poured from one side. The collecting frame 5 is arranged between the screening wheel 4 and the ground-accumulated waste chips, and is driven by the vibration of the screening wheel 4, so that the small-particle waste chips can be effectively separated before the waste chips are transferred to the screening wheel 4, thereby effectively collecting the small-particle waste chips in front of the screening wheel 4. Figure 10

[0030] The principle of the present application is that when the waste chips are crushed, the operator gradually transfers the waste chips to the bottom end of the conveying belt 2 by a tool, and continuously conveys the waste chips into the crusher by the conveying belt 2 for crushing treatment. In the conveying process of the conveying belt 2, the small-particle waste chips rely on their own gravity and the intermittent vibration of the conveying belt 2 caused by the driving of the screening wheel 4, so that the small-particle waste chips fall from the mesh of the conveying belt 2 to the bottom collecting frame 5, thereby reducing the volume of the waste chips entering the crusher for crushing, improving the crushing efficiency, reducing the power consumption and the wear of the crushing cutter.

[0031] The above shows and describes the basic principles, main features and advantages of the present application. Various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.​
