[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Please refer to the appendix. Figures 1-5 The present invention provides a multifunctional sand screening device, including a box 1, a bracket 2 symmetrically fixed at the bottom of the box 1, a sand inlet 3 fixedly connected to the top of the box 1, a sand outlet 4 opened at the bottom of the box 1, a metal debris screening component rotatably installed inside the box 1, and a sand filtration component detachably installed at the bottom inside the box 1.

[0024] The metal debris screening component includes two openings 5, which are respectively opened at both ends of the box 1 and are staggered. Support frames 6 are also fixed at both ends of the box 1. The two support frames 6 are respectively located at the two openings 5. A servo motor 7 is longitudinally fixed at the top of each support frame 6. A rotating seat 8 is fixed at the front end of the output shaft of each servo motor 7. A first guide plate 9 is fixed at the top of each rotating seat 8. The two first guide plates 9 are staggered and pass through the two openings 5. An electromagnetic chuck 10 is fixed at the top of the end of each first guide plate 9 located inside the box 1. Specifically, when the electromagnetic chuck 10 is running, it generates magnetic attraction when energized. Therefore, when sand flows over the first guide plate 9, the metal debris impurities in it can be magnetically attracted by the electromagnetic chuck 10. That is, the device can filter out metal debris in the sand. When the servo motor 7 is running, it can control the rotation of the first guide plate 9, thereby controlling the tilt direction and tilt angle of the first guide plate 9.

[0025] The first guide plate 9 is fixed to an end plate 11 at one end located outside the box 1. The bottom end of each end plate 11 is fixedly connected to a collection hopper 12. The end of each collection hopper 12 is fixedly connected to a conveying pipe 13. The end of each conveying pipe 13 is fixedly connected to a discharge hose 14. Specifically, after the sand passes through the first guide plate 9 and metal fragments are filtered out, the operator can control the servo motor 7 to tilt the first guide plate 9 to the outside of the box 1 (e.g., ...). Figure 5(as shown), then the electromagnetic chuck 10 is de-energized, so that the magnetic force disappears, and the metal scraps flow into the collection hopper 12 through the first guide plate 9 under the action of gravity. Then, they are discharged in a concentrated manner through the conveying pipe 13 and the discharge hose 14. That is, this device is convenient for discharging the screened metal scraps.

[0026] The sand screening assembly includes an impurity outlet 15, which is located on the side of the housing 1. A second guide plate 16 is fixedly and inclinedly to the side of the housing 1, with its end corresponding to and communicating with the impurity outlet 15. A support plate 17 is fixed to the bottom of the inner wall side of the housing 1. An insertion hole 18 is provided on the side of the housing 1. The sand screening assembly also includes a screen plate 19, which passes through the insertion hole 18 and has its end abutting against the top of the support plate 17. The screen plate 19 has several screen holes 20. The screen plate 19, the impurity outlet 15, and the second guide plate are connected. The 16 is inclined and correspondingly set, that is, the sand guided by the first guide plate 9 can flow through the surface of the inclined screen plate 9. At this time, under the sieving action of several screen holes 20, large sand and gravel and other impurities can be screened out. The screened impurities flow out through the impurity outlet 15 and the second guide plate 16. The sand with the impurities removed flows downward through the screen holes 20 and then is discharged through the sand discharge port 4. That is, the device can also filter out sand impurities. Moreover, the screen plate 19 can be disassembled by simply pulling it out, which makes it convenient to clean or replace the clogged screen plate 19.

[0027] A sand collection box 21 is placed below the sand discharge port 4, and an impurity collection box 22 is placed below the second guide plate 16. It should be noted that both the bottom of the sand collection box 21 and the bottom of the impurity collection box 22 are fixed with moving wheels for easy movement. Specifically, the screened sand discharged through the sand discharge port 4 can flow into the sand collection box 21 for centralized collection, and the impurities flowing out through the impurity outlet 15 and the second guide plate 16 can flow into the impurity collection box 22 for centralized collection. That is, this device can conveniently discharge and collect the screened impurities, and can also discharge and collect the screened sand.

[0028] In conclusion, this device is feature-rich, better meets user needs, and is suitable for widespread adoption.

[0029] It should be noted that the device is electrically connected to an external main controller and 220V AC mains power, and the main controller can be an existing technology device that controls switches, etc.

[0030] The usage process of this utility model is as follows: First, the operator controls the operation of the electromagnetic chuck 10, energizing it to generate magnetic attraction. Then, the sand to be screened is added into the housing 1 through the sand inlet 3. The sand is first guided by the first guide plate 9 and flows downwards. While flowing on the first guide plate 9, metal debris and impurities within the sand are magnetically attracted by the electromagnetic chuck 10, thus filtering out the metal debris. The sand with the metal debris filtered out flows to the surface of the screen plate 19 and is then screened through several screen holes 20. Under the filtration action of the several screen holes 20, large-volume impurities such as sand and gravel can be screened out. The screened impurities are discharged through the impurity outlet 15 and the second... The flow from the guide plate 16 flows into the impurity collection box 22. The sand with impurities removed flows downward through the screen holes 20 and then flows into the sand collection box 21 through the sand discharge port 4 for collection. Then, the operator controls the servo motor 7 to tilt the first guide plate 9 to the outside of the box 1. Then, the electromagnetic chuck 10 is de-energized, so that the magnetic force disappears, and the metal scraps flow into the collection hopper 12 under the action of gravity through the first guide plate 9. Then, they are discharged through the conveying pipe 13 and the discharge hose 14. Finally, the operator controls the servo motor 7 to run in the opposite direction and tilt the first guide plate 9 to the inside of the box 1, waiting for the next sand screening.

[0031] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
