Description

Technical Field

[0001] This utility model relates to the field of material screening technology, and in particular to a ceramicized zinc borate powder grading sieve. Background Technology

[0002] In the field of flame retardant materials, ceramicized zinc borate powder is widely used in the production of plastics, rubber, coatings and other products due to its excellent flame retardant and smoke-suppressing properties. The particle size distribution of the powder directly affects its flame retardant effect. Powder with uniform particle size can be more evenly dispersed in the substrate, thus improving the flame retardant efficiency. Therefore, grading sieves have become key equipment for processing ceramicized zinc borate powder, which needs to separate the powder according to particle size and screen out products that meet the production requirements.

[0003] Existing ceramicized zinc borate powder grading sieves mostly adopt a vibrating sieve structure. Their mechanical structure mainly includes a rectangular sieve box, multiple layers of screens installed inside the sieve box, a vibrating motor fixed to the bottom of the sieve box, a support spring connected to the bottom of the sieve box, a feed hopper on one side of the sieve box, and discharge ports at different heights on the other side. The screens are arranged from top to bottom according to their aperture size, from largest to smallest. One end of the support spring is connected to the sieve box, and the other end is fixed to the frame. The technical principle is that the vibrating motor drives the sieve box to perform high-frequency reciprocating vibration. After the ceramicized zinc borate powder enters the sieve box from the feed hopper, it moves along the sieve surface under the action of vibration. Powder smaller than the screen aperture passes through the screen and falls to the lower layer, while powder larger than the aperture continues to move along the sieve surface to the corresponding discharge port for discharge, thus achieving the grading of powders of different particle sizes.

[0004] However, existing technologies struggle to effectively handle agglomerated materials in powders, leading to decreased grading accuracy and reduced screening efficiency. During storage or transportation, ceramicized zinc borate powder is prone to agglomeration due to factors such as humidity and pressure, forming lumps with particle sizes far exceeding the normal range. These agglomerated materials, upon entering the screen box, cannot pass through any layer of screen due to their excessive size, accumulating on the screen surface. This not only clogs the screen pores, preventing even normally sized powders from passing smoothly, but also disrupts the powder's movement trajectory on the screen surface, causing some fine powder to be discharged from the coarse material outlet along with the coarse powder, resulting in grading accuracy deviations. Furthermore, the accumulated agglomerated material requires regular manual cleaning, increasing the workload of operators, interrupting screening operations, and reducing overall production efficiency, making it difficult to meet the production requirements for continuous, high-precision grading of ceramicized zinc borate powder. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ceramicized zinc borate powder grading sieve, which aims to improve the problem in the prior art that it is difficult to effectively process agglomerated materials in powder, resulting in reduced grading accuracy and affecting sieving efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ceramicized zinc borate powder grading sieve, comprising a device body, a spring fixedly connected to the outer wall of the device body, a vibrating base fixedly connected to one end of the spring, a discharge port fixedly connected to the outer wall of the device body, and a dispersing component provided on the outer wall of the device body. The dispersing component includes a connecting plate, the outer wall of which is fixedly connected to the outer wall of the device body. A connecting block is fixedly connected to the outer wall of the connecting plate. A bolt is provided on the inner wall of the connecting block. A connecting column is threadedly connected to the outer wall of the bolt. A feed inlet is fixedly connected to the outer wall of the connecting column. A screen and a motor are provided on the inner wall of the feed inlet. An eccentric wheel is fixedly connected to the output end of the motor.

[0007] Furthermore, a second screen is provided on the inner wall of the device body, and a handle is fixedly connected to the outer wall of the second screen.

[0008] Furthermore, a second connecting plate is fixedly connected to the outer wall of the device body, and a second connecting plate is fixedly connected to the outer wall of the second connecting plate.

[0009] Furthermore, a tension spring is fixedly connected to the inner wall of the second connecting plate, and a connecting post is fixedly connected to one end of the tension spring.

[0010] Furthermore, a connecting column four is fixedly connected to the outer wall of the connecting column three, and a connecting plate three is provided on the inner wall of the connecting column four.

[0011] Furthermore, the outer walls of the connecting plate are fixedly connected to limit posts, and the inner walls of the limit posts are rotatably connected to inclined columns.

[0012] Furthermore, the inner wall of the inclined column is fixedly connected with bolt two, and the outer wall of bolt two is threadedly connected to the inner wall of connecting column four.

[0013] Furthermore, the outer wall of the third connecting column is slidably connected to the second connecting column, and the outer wall of the second bolt is rotatably connected to the inner wall of the limiting column.

[0014] This utility model has the following beneficial effects: In this invention, the eccentric wheel driven by the starting motor initially disperses the agglomerated material on the screen at the feed inlet, effectively breaking up agglomerated zinc borate ceramic powder, preventing large pieces of material from clogging the screening channel, ensuring smooth subsequent grading and screening, and improving screening uniformity and efficiency. At the same time, the bolts on the rotating device body can disengage the feed inlet connecting column from the threaded connection, enabling quick replacement of the feed inlet. It can flexibly adapt to different feed specifications according to the characteristics of the powder, further optimizing the grading and screening efficiency and enhancing the applicability of the equipment.

[0015] In this invention, rotating the bolt drives the inclined column to move, releasing the restriction on the limiting column and allowing the limiting column to release its restriction on the handle. At the same time, the connecting plate outside the limiting column rotates inside the connecting column, and the connecting column slides inside another connecting column with the help of the tension spring, realizing quick screen replacement. This structure is easy to operate and can quickly complete the screen disassembly and assembly. It is convenient to replace screens of different specifications according to the powder particle size requirements, ensuring grading accuracy. At the same time, the components work together stably, improving the convenience of equipment maintenance and the flexibility of use. Attached Figure Description

[0022] Specifically, the second screen 22 inside the device body 4 is used for powder classification and screening. The handle 14 facilitates its disassembly and assembly.

The second connecting column 15 guides the third connecting column 17 to ensure stable limit.

[0023] Working principle: When it is necessary to classify and screen agglomerated zinc borate powder, firstly, the motor 8 is started, which drives the eccentric wheel 12 to initially break up the agglomerated material on the screen 1 inside the feed inlet 2. After being broken up, the powder enters the main body 4 of the device. The vibrating base 5 is activated to achieve high-frequency vibration, so that part of the powder is collected through the discharge port 3 and part of the powder continues to be screened downward through the screen 22, thereby achieving grading. Springs 6 are also installed in the main body 4 and the vibrating base 5 to reduce the vibration of the equipment and avoid damage to the equipment. In addition, when it is necessary to replace the feed inlet 2, the connecting column 11 outside the feed inlet 2 is disengaged from the threaded connection of the bolt 10 by rotating the bolt 10 outside the device body 4, thereby replacing the feed inlet 2 to improve the efficiency of grading and screening. Secondly, when it is necessary to replace the screen 22, by rotating the bolt 218, the inclined column 19 is moved accordingly, thereby releasing the inclined column 19 from the restriction of the limiting column 20, realizing the limitation of the limiting column 20 on the handle 14. At the same time, the connecting plate 321 connected to the outside of the limiting column 20 makes it rotate in the connecting column 423. At this time, the connecting column 317 is also caused by the force of the tension spring 16 to slide in the connecting column 225 outside the connecting column 423.
