DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] Please refer to the attached Figure 1-4 The utility model provides a closed integrated screening device and equipment, including a shell 1, a feeding port 2 is opened on one side of the top of the shell 1, a feeding hopper 3 is fixedly connected above the feeding port 2, a cover plate 4 is hinged on the top of the feeding hopper 3, and the steel slag to be recycled and processed is added into the shell 1 through the feeding hopper 3 and the feeding port 2. Under the action of the cover plate 4, the steel slag can be effectively prevented from splashing during the processing process. Two steel slag discharge ports 5 are fixedly connected at the bottom of the shell 1, and a partition plate 6 is vertically fixed at the bottom of the inner wall of the shell 1. The partition plate 6 is located between the two steel slag discharge ports 5, which can be used to separate and discharge the steel slag after screening according to the volume size. A crushing component, a separation component and a screening component are respectively arranged from top to bottom inside the shell 1;

[0021] The crushing assembly includes two crushing rollers 7 driven by a motor (not shown in the figure), the two crushing rollers 7 are meshed with each other, and the two crushing rollers 7 are located directly below the feed port 2, that is, when the steel slag to be recycled is fed through the feed port 2, it can be first squeezed and crushed by the two crushing rollers 7 driven by the motor;

[0022] The separation assembly includes a plurality of guide plates 8 arranged obliquely, the ends of the plurality of guide plates 8 are all obliquely fixed on both sides of the inner wall of the shell 1, and the plurality of guide plates 8 are staggeredly arranged in the shell 1, and an electromagnetic chuck 9 is fixed on the top of each guide plate 8. It should be noted that the electromagnetic chuck is a kind of electromagnetic principle, which generates magnetic force by energizing the internal coil, and demagnetizes when the coil is powered off and the magnetic force disappears. Therefore, under the action of the plurality of guide plates 8, the crushed steel slag and the slag can flow downward in sequence, and when the electromagnetic chuck 9 is in operation, a magnetic attraction can be generated to adsorb the steel slag, and the slag continues to flow downward, so that the crushed steel slag and the slag can be separated in time;

[0023] The separation component also includes a support plate 10, the end of the support plate 10 is fixed to the side of the inner wall of the shell 1, and an electric push rod 11 is vertically fixed to the top of the support plate 10. It should be noted that the electric push rod is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. A support block 12 is fixed to the top of the electric push rod 11, and a guide plate 13 is fixed to the top of the support block 12 at an angle. The guide plate 13 is located below a plurality of guide plates 8, and the guide plate 13 is staggered with a plurality of guide plates 8. An electromagnetic suction cup 14 is fixed to the top of the guide plate 13, that is, the crushed steel slag and slag can flow downward to the guide plate 13 and the electromagnetic suction cup 14, and then continue to flow. A slag discharge port 15 is opened on the side of the shell 1, and a slag discharge plate 16 is fixed in the slag discharge port 15 at an angle. Therefore, when the electric push rod 11 drives the guide plate 13 and the electromagnetic suction cup 14 to move up to contact with the slag discharge plate 16 (such as Figure 1 As shown), the slag that is not magnetically attracted can be discharged through the slag discharge plate 16 to complete the separation of the crushed steel slag and slag impurities;

[0024] The screening assembly includes a screening plate 17, the end of which is fixed obliquely to the inner wall side of the housing 1, the upper end of the screening plate 17 is located below the upper end of the slag feeding plate 16, and the bottom end of the screening plate 17 is fixed to the top of the partition 6. A plurality of screening holes 18 are evenly arranged on the screening plate 17, so when the electric push rod 11 drives the guide plate 13 and the electromagnetic suction cup 14 to move downward and no longer contact the slag feeding plate 16 (such as Figure 2 As shown), at this time, the electromagnetic suction cup 1 9 and the electromagnetic suction cup 2 14 are powered off, and then the previously magnetically attracted steel slag moves down to the screening plate 17 through the guide plate 1 8 and the guide plate 2 13 under the action of gravity, and then is screened through a plurality of screen holes 18, the steel slag with a smaller volume passes through the screen holes 18 and is then discharged through a steel slag discharge port 5, and the steel slag with a larger volume continues to flow downward from the screening plate 17 and is then discharged through another steel slag discharge port 5, thereby the steel slag separated from the slag impurities is screened according to the volume size;

[0025] Two slag collecting boxes 19 are placed under the shell 1, and the two slag collecting boxes 19 are respectively located under the two slag discharge ports 5. A slag collecting box 20 is placed on one side of the shell 1, and the slag collecting box 20 is located under the bottom end of the slag discharge plate 16;

[0026] It should be noted that the device and equipment are electrically connected to an external main controller and 220V AC power, and the main controller can be a computer or other existing technical equipment for control.

[0027] The use process of the utility model is as follows: the technicians in this field firstly energize the motor, electromagnetic suction cup 1 8 and electromagnetic suction cup 2 13 driving the crushing roller 7 through the external main controller, and control the operation of the electric push rod 11, so as to drive the guide plate 2 13 and the electromagnetic suction cup 2 14 to move up to the position in contact with the slag unloading plate 16, and then feed the steel slag to be recycled and processed through the feed hopper 3 and the feed port 2, and the steel slag can be first squeezed and crushed by the two crushing rollers 7 driven by the motor, and the crushed steel slag and the slag flow downward in sequence under the action of the guide plates 1 8 and the guide plates 2 13, and when the electromagnetic suction cup 1 9 and the electromagnetic suction cup 2 13 are energized, a magnetic attraction can be generated, thereby adsorbing the steel slag, and the slag continues to flow downward, that is, the crushed steel slag and the slag are separated in time, and the slag that is not magnetically attracted can be discharged into the slag collecting box 20 through the slag unloading plate 16 at this time, so as to complete the separation of the crushed steel slag and the slag impurities;

[0028] Then, the technicians in this field first control the operation of the electric push rod 11 through the external main controller, driving the guide plate 2 13 and the electromagnetic suction cup 2 14 to move downward, no longer in contact with the slag discharge plate 16, and cut off the power to the electromagnetic suction cup 1 9 and the electromagnetic suction cup 2 13 to make their magnetic force disappear. The steel slag that was previously magnetically attracted moves down to the screening plate 17 through the guide plate 1 8 and the guide plate 2 13 under the action of gravity, and then is screened through a number of sieve holes 18. The steel slag with a smaller volume passes through the sieve holes 18 and is then discharged into the corresponding steel slag collecting box 19 through a steel slag discharge port 5. The steel slag with a larger volume continues to flow downward from the screening plate 17, and is then discharged into the corresponding steel slag collecting box 19 through another steel slag discharge port 5, so that the steel slag separated from the slag impurities is screened according to its volume. In summary, the device and equipment can realize the integrated functions of crushing, separation and screening, and greatly improve the efficiency of steel recycling processing.
