Description

Technical Field

[0001] The utility model relates to the technical field of vibration screen equipment, and more specifically to a material collecting device for negative electrode material screening equipment. Background Art

[0002] In the powder material preparation industry, especially in the production of negative electrode materials, screening equipment is used to screen the powder materials to remove foreign matter from the powder materials. As the client's requirements for the use of powder materials increase, the number of screen meshes used in the screening equipment is getting higher and higher. As the number of screen meshes increases, the screening effect of powder materials will also become better and better. In order to be able to screen out particles of different sizes, screens of different meshes will be added to the vibrating screen to achieve the effect of multiple screening of the material. Multi-layer screening helps to more accurately control the particle size distribution of the final product and improve product quality.

[0003] In order to improve the efficiency of the screen, a return tray will be set between two adjacent screens. The return tray is also called a collection hopper. The bottom of the return tray has an arc, and a hole is opened at the bottom to guide the material falling from the upper screen to the center of the bottom screen, which helps the material to contact the screen more fully and improve the screening efficiency. Chinese patent application number 202220923063.4 discloses a screen and an ultrasonic vibrating screen using the screen. A collection hopper is installed inside the vibrating screen. The collection hopper is located between two adjacent screens, so that the fallen raw materials can be well gathered, making it convenient for secondary screening. The screen and the ultrasonic vibrating screen using the screen also have the following problems in daily production and use;

[0004] The height of the hopper cannot be adjusted. When the hopper is too low, when screening a large amount of material, it will cause the accumulation of raw materials in the center of the lower screen, thereby hindering the efficiency of material movement, causing blockage or slowing down the material screening speed; and when the height of the hopper is too high, although it can reduce the accumulation of materials at the bottom, the material falls freely from a higher position, reducing the sliding or rolling time on the screen surface, which is not conducive to fine particles passing through the sieve holes, reducing the screening efficiency, especially for fine-grained materials that require a longer screening time. At the same time, the impact force increases when the material falls from a high place, which will increase the impact wear on the screen, shorten the service life of the screen, and increase maintenance costs and downtime.

[0005] Therefore, it is necessary to propose a material collecting device for negative electrode material screening equipment to solve the above problems. Utility Model Content

The height of the inner sleeve ring 103 is greater than twice the height of the adjustment slot 104. When the fixing rod 105 is located in the adjustment slot 10 4, the top part of the inner ring 103 can also cover the top part of the adjustment groove 104 to prevent the material from running out. The same is true when the fixing rod 105 is at the highest point. An inclined adjustment groove 104 is provided on the outer ring surface of the middle cylinder 101. The adjustment groove 104 is inclined, and the height of one end is higher than the other end.

[0037] Specifically, refer to Figure 6 and Figure 7 One end of the spline sleeve 113 away from the adjustment handle 114 is connected to a circular plate 117 , and a spring 118 pushes the spline sleeve 113 to move toward the gear 110 through the circular plate 117 . The spring 118 is connected between the circular plate 117 and the inner wall of the cavity 109 .

[0038] Specifically, refer to Figure 8 , both ends of the outer ring 107 are connected with ribs 119, and strip grooves 120 are symmetrically opened on the ribs 119. When the multiple outer rings 107 move outward, the connecting component 121 will move in the strip groove 120. The connecting component 121 is used to limit the multiple outer rings 107 from rotating. The connecting component 121 is arranged in the strip groove 120, and two adjacent ribs 119 are connected by the connecting component 121.

[0039] Specifically, refer to Figure 8The connecting assembly 121 is composed of a strip plate, a nut, a spring 118 and a U-shaped rod.

[0042] When it is necessary to adjust the height of the return tray 102 in the middle tube 101, the adjustment handle 114 is first pulled out, and the adjustment handle 114 drives the protrusion 116 to be pulled out from the block 115, so that the block 115 loses its restrictive effect on the protrusion 116, and the adjustment handle 114 drives the spline sleeve 113 and the annular plate 117 located in the cavity 109 to move, and the spring 118 on one side of the annular plate 117 is compressed. At this time, the adjustment handle 114 is rotated, and the adjustment handle 114 will drive the spline rod 112 to rotate through the spline connection, and the spline rod 112 drives the threaded sleeve 106 and the gear 110 on one side. The ring 111 rotates, and when the gear ring 111 rotates, it drives multiple other gears 110 to rotate through threaded connection. The multiple gears 110 drive the threaded sleeve 106 on the other side to rotate. The threaded sleeve 106 drives the outer sleeve 107 to move toward the side away from the inner sleeve 103 through the thread of the outer wall, thereby increasing the distance between the inner sleeve 103 and the outer sleeve 107, making it lose the ability to be fixed on the middle cylinder 101. At this time, the fixing ring 108 can be held by hand to drive the fixing rod 105 to move in the adjustment groove 104, so as to adjust the height of the return tray 102 in the middle cylinder 101;

[0043] After the position is determined, the adjustment handle 114 is rotated in the reverse direction to reduce the distance between the outer ring 107 and the inner ring 103, thereby fixing the return material tray 102 inside the middle cylinder 101;

[0044] At this time, the adjustment handle 114 is released, and the spring 118 in the cavity 109 is reset, driving the spline sleeve 113 to move toward the side close to the gear 110 through the annular plate 117. The spline sleeve 113 will drive the protrusion 116 on one side of the adjustment handle 114 to insert into the groove in the block 115. The protrusion 116 can fix the adjustment handle 114 to prevent shaking during use.
