[0002] In the production of metal materials, screening and impurity removal is a crucial step in ensuring product quality. Existing screening and impurity removal devices for metal material production are mainly used to remove impurities and non-compliant particle sizes from metal powders and granules. These impurities may include non-metallic substances (such as dust and sand), excessively large or small metal particles, etc., and their presence directly affects the performance and quality of the final product.

[0003] However, for metal materials mixed with various types of impurities, single-function screening and impurity removal equipment often requires multiple processes to achieve the desired effect. There is an urgent need for a screening and impurity removal device for metal material production to solve the above-mentioned problems. Utility Model Content

This utility model combines vibration screening, magnetic screening and air separation. First, it can remove lighter impurities through air separation, and then it can remove large or small particles through vibration. In this process, the metal impurities can be magnetically adsorbed.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a screening and impurity removal device for metal material production, comprising a screening and impurity removal box, a screening frame, and a connecting frame. Fan frames are bolted to the left and right sides of the upper end of the screening and impurity removal box. Small fans are installed inside each of the two fan frames.

Multiple spring-limiting cylinders are installed on the upper ends of the two side plates via flanges and bolts. Each of the multiple spring-limiting cylinders has a longitudinally inserted return spring. The suspended portion of the screening frame is in the screening and impurity removal... Inside the screening box, multiple connecting blocks are longitudinally welded to the left and right sides of the lower end of the screening frame. A vibrator is installed on the left end of the screening frame by bolts. First welding strips are welded to the left and right ends of the screening frame.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a screening and impurity removal device for metal material production, including a screening and impurity removal box 1, a screening frame 9, and a connecting frame 13. Fan frames 3 are bolted to the left and right sides of the upper end of the screening and impurity removal box 1. Small fans 4 are installed inside each of the two fan frames 3. Side plates 5 are welded to the left and right ends inside the screening and impurity removal box 1. Multiple spring limiting cylinders 6 are installed on the upper ends of the two side plates 5 via flanges and bolts. Each spring limiting cylinder 6 contains a longitudinally inserted return spring 7. The screening frame 9 is suspended inside the screening and impurity removal box 1, and multiple connecting blocks 8 are longitudinally welded to the left and right sides of the lower end of the screening frame 9. A vibrator 21 is bolted to the left end. The left and right ends of the screening frame 9 are welded with first welding plates 10. The upper ends of the two first welding plates 10 are fixed with large-hole magnet pieces 12 by bolts. The lower ends of the large-hole magnet pieces 12 are combined with large-hole screens 11. The connecting frame 13 is welded to the lower end of the screening and impurity removal box 1. The left and right ends of the connecting frame 13 are welded with second welding plates 14. The upper ends of the two second welding plates 14 are fixed with small-hole magnet pieces 16 by bolts. The lower ends of the small-hole magnet pieces 16 are combined with small-hole screens 15. This design solves the problem that the original single-function screening and impurity removal equipment often requires multiple processes to achieve the ideal effect.

[0019] As the first embodiment of this utility model: a feeding port 2 is provided at the upper end of the screening and impurity removal box 1, and a dust discharge pipe 18 is installed at the lower left end of the screening and impurity removal box 1. A filter pipe 19 is installed inside the dust discharge pipe 18. An activated carbon plate and a high-efficiency filter screen are installed longitudinally inside the filter pipe 19. The lighter impurities blown out by the two small fans 4 can be adsorbed and filtered by the added activated carbon plate and high-efficiency filter screen.

[0020] Multiple connecting blocks 8 are movably locked inside multiple spring limiting cylinders 6 and abut against multiple return springs 7 respectively. By adding multiple connecting blocks 8, which are movably locked inside multiple spring limiting cylinders 6 and abut against multiple return springs 7 respectively, multiple connecting blocks 8 can be driven to vibrate on the upper side of multiple return springs 7 when the vibrator 21 is vibrating, thereby realizing the vibration screening operation of the screening frame 9.

[0021] The front end of the screening and impurity removal chamber 1 is equipped with a movable door 20 via multiple hinges. This movable door 20 allows the front end of the screening and impurity removal chamber 1 to be easily opened, allowing the impurity collection box 17 to be removed. An external wrench can then be used to unscrew the bolts at the large-hole magnet 12 and the small-hole magnet 16, facilitating the removal of the filtered impurities and the collection of adsorbed metal materials. The impurity collection box 17 is located at the lower interior of the screening and impurity removal chamber 1, allowing smaller impurities to be collected.

[0022] As a second embodiment of this utility model: the mixed material is added into the screening and impurity removal box 1 through the feeding port 2, and it will fall onto the large-hole magnetic plate 12. The vibrator 21 is started, and the vibrator 21 drives the screening frame 9 to vibrate (during this process, multiple connecting blocks 8 and reset springs 7 vibrate within multiple spring limit cylinders 6). This allows qualified and smaller materials to pass through the large-hole magnetic plate 12 and the large-hole screen 11 and fall onto the small-hole magnetic plate 16. Larger materials will be intercepted on the large-hole magnetic plate 12, and due to the magnetic attraction of the large-hole magnetic plate 12, metal materials will be attracted. Smaller materials will then pass through the small-hole magnetic plate 16 and the small-hole screen 15 and fall into the impurity collection box 17. Smaller metal materials will be attracted by the small-hole magnetic plate. 16. Magnetic adsorption. Simultaneously, two small fans 4 are activated. The two small fans 4 can discharge light impurities in the screening and impurity removal box 1 through the dust discharge pipe 18. During this process, the light impurities will be adsorbed and filtered by the activated carbon plate and the high-efficiency filter. After completion, open the movable baffle 20. Use an external wrench to unscrew the bolts at the large-hole magnetic plate 12 and the small-hole magnetic plate 16. This will also make it easy to remove the large-hole magnetic plate 12 and the small-hole magnetic plate 16. Then, tilt the large-hole magnetic plate 12 and the small-hole magnetic plate 16. The non-metallic materials that have been intercepted and filtered will fall downwards, while the metallic materials that have not fallen will still be adsorbed at the large-hole magnetic plate 12 and the small-hole magnetic plate 16, which makes it easy for the staff to remove and collect them for processing.
