Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] An electrolytic manganese slag slurry screening machine, such as Figure 1As shown, it includes a mounting frame 5, a main body 1, a feeding hopper 7, an adjusting device, an elastic support device 4, and a vibration device 3. The main body 1 is equipped with a feed inlet 6, a fine discharge outlet 2, and a coarse discharge outlet 9, as shown. Figure 2 As shown, a screen 14 is installed inside the main body 1; the elastic support device 4 is fixedly connected to the mounting frame 5, the main body 1 is connected to the elastic support device 4 and is inclined, the vibration device 3 is fixedly connected to the mounting frame 5 and connected to the main body 1, and the vibration device 3 is used to generate vibration; the feeding hopper 7 is connected to the mounting frame 5 through an adjustment device, and the bottom of the feeding hopper 7 faces the feed inlet 6; as shown Figure 3 As shown, the adjusting device includes a reciprocating screw 10, a first driving device 19, and a limiting rod 13; the reciprocating screw 10 is rotatably connected to the mounting frame 5, the first driving device 19 is connected to the reciprocating screw 10, and the limiting rod 13 is fixedly connected to the mounting frame 5; a first connector 11 and a second connector 12 are fixedly connected to both sides of the feeding hopper 7, the first connector 11 is threadedly connected to the reciprocating screw 10, and the second connector 12 is slidably connected to the limiting rod 13.

[0029] The feed inlet 6 is used to feed materials into the main body 1, the fine discharge outlet 2 is used to discharge the screened fine materials, the coarse discharge outlet 9 is used to discharge the screened coarse materials, and the screen 14 is used to screen the materials. The elastic support device 4 is used to support the main body 1 and facilitate the vibration of the main body 1. The elastic support device 4, together with the vibration device 3, can ensure that the main body 1 vibrates. After the main body 1 vibrates, the materials inside are screened through the internal screen 14. The inclined main body 1 allows the materials to slide automatically downward under the action of gravity, thereby reducing the risk of the screen 14 being blocked. At the same time, it can also make the materials more evenly distributed on the surface of the screen 14, improving the screening efficiency. The adjusting device is used to make the feeding hopper 7 reciprocate, so that the feeding hopper 7 can evenly feed the materials onto the screen 14 inside the main body 1, preventing the materials from accumulating in a certain part of the screen 14 and causing blockage. Specifically, the first drive device 19 drives the reciprocating screw 10 to rotate, the reciprocating screw 10 drives the first connecting head 11 to reciprocate, and further drives the feeding head to reciprocate. The limiting rod 13 is mainly used to ensure the stability of the feeding hopper 7. It should be noted that the reciprocating screw 10 is a type of screw that enables the slider to reciprocate without changing the direction of the main shaft rotation. The reciprocating screw 10 is a form of three-dimensional cam pair, characterized by two threaded grooves with the same pitch but opposite directions of rotation. The two ends are connected by a transition curve. The rotation of the screw causes the side of the helical groove to push the slider placed within the helical groove to perform axial reciprocating motion. The reciprocating screw 10 is existing technology, and its specific structure will not be described in detail here.

[0030] In a preferred embodiment, such as Figure 2As shown, the bottom of the main body 1 is provided with a first inclined section 18 and a second inclined section 17. The first inclined section 18 and the second inclined section 17 are inclined in opposite directions, and the downward inclined side of the first inclined section 18 is close to the downward inclined side of the second inclined section 17. The fine discharge port 2 is located between the first inclined section 18 and the second inclined section 17. The downward-facing side of the first inclined section 18 and the downward-facing side of the second inclined section 17 are close to each other, forming a V-shaped structure. The fine discharge port 2 is located between these two inclined sections, which can improve the collection efficiency of fine materials.

[0031] In a preferred embodiment, such as Figure 2 As shown, the main body 1 includes a mounting body 16 and a top cover 15, which are detachably connected. A feed inlet 6 and a coarse discharge outlet 9 are located on the top cover 15, and a screen 14 is connected to the mounting body 16. The connection between the top cover 15 and the mounting body 16 is designed to be detachable, allowing the top cover 15 to be easily removed for maintenance, cleaning, or replacement of the screen 14 without disassembling the entire device.

[0032] In a preferred embodiment, such as Figure 1 As shown, a tension spring 8 is provided between the main body 1 and the mounting frame 5, with both ends of the tension spring 8 connected to the mounting frame 5 and the main body 1, respectively. The tension spring helps to improve the vibration effect, enabling the main body 1 to vibrate more effectively under the action of the vibration device 3, thereby improving the screening efficiency.

[0033] In a preferred embodiment, such as Figure 5 As shown, the elastic support device 4 includes a mounting plate 25, a base plate 30, a compression spring 27, a base 29, and a support column 28. The mounting plate 25 is fixedly connected to the main body 1, the base plate 30 is fixedly connected to the bottom of the mounting plate 25, the base 29 is located below the base plate 30, the compression spring 27 is connected at both ends to the base plate 30 and the base 29 respectively, and the support column 28 is connected to the base 29. Further optimized, several support vertical plates 26 are fixedly connected to one side of the mounting plate 25. The elastic support device 4 ensures the stability of the main body 1 during operation. The compression spring 27 provides sufficient elastic support, allowing the main body 1 to maintain an appropriate displacement range during vibration operation without affecting the overall structure of the equipment. The design of the support column 28 and the support vertical plates 26 enhances the stability of the equipment, enabling the elastic support device 4 to better bear the weight and dynamic loads from the main body 1, improving the safety and reliability of the equipment. The addition of the support vertical plates 26 not only increases the rigidity of the structure but also effectively distributes the load to a wider area, reducing the pressure on a single point and thus avoiding potential damage.

[0034] In a preferred embodiment, such as Figure 4As shown, the vibration device 3 includes a connecting seat 21, an eccentric wheel 22, a connecting shaft 20, a second drive device 23, and a support platform 24. The connecting seat 21 is fixedly connected to the main body 1, the eccentric wheel 22 is fixedly connected to the connecting shaft 20, the connecting shaft 20 and the connecting seat 21 are rotatably connected, the support platform 24 is fixedly connected to the mounting frame 5, the second drive device 23 is connected to the support platform 24, and the second drive device 23 is flexibly connected to the connecting shaft 20. The second drive device 23 drives the connecting shaft 20 to rotate. The eccentric wheel 22, in conjunction with the rotating connecting shaft 20, causes uneven mass distribution of the eccentric wheel 22, generating centrifugal force, thereby achieving efficient vibration and promoting material flow and screening. The flexible connection design of the second drive device 23 allows the vibration device 3 to adapt to different vibration conditions and requirements, effectively coping with variable speed operation conditions, reducing the impact on the drive system, and lowering the failure rate.

[0035] In a preferred embodiment, both the first drive device 19 and the second drive device 23 are electric motors. Compared to other power sources, electric motor drives can provide higher power efficiency and can operate continuously and stably.

[0036] In a preferred embodiment, the feeding hopper 7 has a structure with a large top opening and a small bottom opening. The large top opening of the feeding hopper 7 allows it to easily receive a large amount of material from the outside, ensuring sufficient passage during loading and improving loading efficiency. The small bottom opening, by limiting the outflow of material, helps to better control the material and ensures that the material can accurately enter the main body 1 through the feed inlet 6.

[0037] In a preferred embodiment, the screen 14 is detachably connected to the main body 1. This detachable design greatly simplifies the maintenance process of the screen 14, making regular cleaning or replacement efficient and ensuring the equipment remains in optimal working condition. Different materials may require screens 14 with different aperture sizes; by quickly replacing the screen 14, the equipment can be adapted to specific situations, improving production flexibility and meeting the needs of handling different materials.
