Description

Technical Field

[0001] The invention relates to the field of crushing, in particular to a rare earth phosphor waste mixing and stirring device with a crushing function. Background Art

[0002] Phosphor, commonly known as glow-in-the-dark powder, is made from high-purity single rare earth compounds and other fluorescent-grade chemical raw materials processed at high temperatures. When exposed to natural light, fluorescent light, ultraviolet light, etc., phosphor can store light energy, and then slowly release it in the form of fluorescence after the light exposure stops. It can glow for a long time at night and in the dark. Since rare earth tri-color phosphors are currently commonly used, if they are not properly treated, the recycling process of this rare earth element is prone to secondary pollution. Therefore, the phosphor waste needs to be crushed before treatment.

[0003] Since phosphors are powdery in texture, but waste materials often have a compacted, blocky solid structure, the treatment of phosphor waste requires two processes: crushing and grinding. The grinding stage has high requirements for the particle size after grinding. This means that a single device cannot complete the crushing and grinding processes simultaneously. Multiple devices are required, which takes up a lot of space. In addition, the crushed particles need to be transferred in the middle. The large-scale dispersion of powder during the transfer process will also cause environmental pollution and pose a threat to workers' health.

[0004] Therefore, a new type of rare earth phosphor waste mixing and stirring device with a crushing function is needed to solve the above problems and simultaneously complete the crushing and grinding of the phosphor waste. Summary of the Invention

[0029] The following is a diagram of the present invention Figures 1-8 , clearly and completely describe the specific technical solutions of the present invention;

[0031] This embodiment provides a rare earth phosphor waste mixing and stirring device with a crushing function, comprising a grinding bowl 1, the top and side of which are respectively provided with a top cover 5 and a discharge port 7 for feeding and discharging materials. The bottom of the grinding bowl 1 is connected to a drive motor 2, the output end of the drive motor 2 is connected to a drive shaft 3 in the center of the grinding bowl 1, and a crushing hammer 4 is eccentrically connected to the drive shaft 3. The crushing hammer 4 is arranged to fit the side walls and bottom surface of the grinding bowl 1, and the interior is a hollow centripetal fan blade structure.

[0032] The waste blocks are crushed by setting the hollow centripetal fan blade structure crushing hammer 4 in cooperation with the grinding bowl 1 structure. The centripetal fan blade structure improves the grasping ability of the waste blocks. At the same time, the gap between the fan blade structure also provides a retention space for the waste blocks. While ensuring a small gap between the crushing hammer 4 and the grinding bowl 1, the crushing load is reduced. There is no need to refine the waste blocks in one go. That is, the waste is crushed and refined through multiple actions while ensuring the maximum refining ability, reducing the burden, and then the refined waste is ground by the bottom contact surface.

[0033] Among them, the top of the grinding bowl 1 is fixedly connected with an annular side drive ring 6, and the inner side of the side drive ring 6 has a protruding toothed disc structure. The top of the crushing hammer 4 is provided with a toothed disc structure that engages with the side drive ring 6 for transmission. The crushing hammer 4 is driven by the toothed disc to improve the driving force.

[0034] The pulverizing hammer 4 includes a grinder 41, a vibrating hammer 42, and a driving cover 45. The grinder 41 is a centripetal impeller structure with a hollow interior. The driving cover 45 is fixedly connected to the top and is rotatably connected to the drive shaft 3 through the driving cover 45. The vibrating hammer 42 is provided inside the grinder 41 and reciprocates up and down.

[0035] By disposing the vibrating hammer 42 , an up and down vibrating impact force can be generated during the grinding process, thereby improving the grinding effect.

[0036] Specifically, the vibrating hammer 42 includes a hammer body 421 and a limiter 423. The hammer body 421 is slidably disposed inside the grinder 41 and the drive cover 45. The top of the hammer body 421 is connected to the limiter 423. There are protruding transmission keys on both sides of the limiter 423. There are corresponding groove structures on the drive shaft 3 to limit the angle of the limiter 423. There is an annular inclined surface structure inside the drive cover 45, which engages with the transmission key of the limiter 423 to drive the vibrating hammer 42 up and down.

[0037] The vibration hammer 42 is driven by the interference between the annular inclined surface and the transmission key on the vibration hammer 42, thereby reducing the number of driving components.

[0038] Furthermore, a laterally protruding annular connecting member 422 is provided between the hammer body 421 and the limiting member 423. The hammer body 421 and the limiting member 423 are indirectly threadedly connected via the connecting member 422. A mounting plate 44 is fixed between the grinder 41 and the drive cover 45 and is sleeved on the outer side of the vibrating hammer 42. A vibrating spring 43 is provided between the mounting plate 44, the connecting member 422, and the hammer body 421 to elastically support the vibrating hammer 42.

[0039] The vibration hammer 42 is supported by the vibration spring 43, which reduces the vertical force required to drive the vibration hammer 42 and reduces the load of the vibration movement. At the same time, through the elastic connection, the one-way hammering is changed to reciprocating bouncing when the spring is reset, which not only reduces the impact on the structure but also refines the vibration effect and the vibration activity effect.

[0040] Furthermore, when the vibrating hammer 42 is not driven by the annular inclined surface of the driving cover 45 but only supported by the vibrating spring 43, the transmission key height of the top limiter 423 corresponds to the midpoint position of the annular inclined surface of the driving cover 45, so that the vibrating spring 43 has a two-way activity space for the action on the vibrating hammer 42, providing more fine up and down vibrations and improving the grinding effect.

[0041] Specifically, the grinder 41 includes a grinding disc 411, grinding strips 412, guide blades 413, and a connecting cover 414. The upper surface of the grinding disc 411 is connected to an annularly distributed arc-shaped fan-shaped guide blade 413, and the top of the guide blade 413 is connected to the connecting cover 414. The grinding disc 411, guide blade 413, and connecting cover 414 together form a centripetal fan wheel structure. The vibrating hammer 42 is set in the central gap of the annularly distributed guide blade 413. The bottom surface of the grinding disc 411 is fixed with an arc-shaped grinding strip 412 by screws.

[0042] The centripetal impeller structure formed by the grinding disc 411, the guide vane 413 and the connecting cover 414 can rotate after being driven, and can guide the crushed waste fragments through the guide vane 413 structure and guide them to the central vibrating hammer 42 position. The vibrating hammer 42 further refines the fragments, and then the refined overflowed powder waste is finally ground and refined by the grinding bar 412 on the bottom to reduce the particle size. The grinding bar 412 is fixed with screws to facilitate the replacement of the grinding bar 412 after it is worn.

[0043] Furthermore, a through hole structure corresponding to the bottom surface of the vibrating hammer 42 is opened at the center of the bottom of the grinding disc 411;

[0044] By providing the through hole, the vibrating hammer 42 changes the crushing of the waste block to biting, thereby avoiding the problem of the waste sticking to the bottom surface of the vibrating hammer 42 and the pressed plate forming a block after being pressed.

[0045] Furthermore, the upper surface of the grinding disc 411 is a conical surface with high edges and low center, which guides the waste blocks entering the centripetal impeller structure of the grinder 41 to flow to the active position of the central vibrating hammer 42 for crushing.

[0046] Furthermore, the guide piece 413 is arranged in the opposite direction of the arc warping of the grinding strip 412;

[0047] The waste materials on the upper and lower sides of the grinding disc 411 are diverted in opposite directions. The upper side diverts the flow toward the center to cooperate with the vibration hammer 42 to crush the small pieces of waste materials. The lower side diverts the crushed and ground powder outward to avoid powder accumulation in the center.

[0048] When implementing the technical solution described in this embodiment, the fluorescent powder waste is injected into the grinding bowl 1 through the top cover 5, and the driving motor 2 is started. The driving motor 2 drives the crushing hammer 4 to perform orbital motion along the side wall of the grinding bowl 1 through the driving shaft 3. At the same time, the crushing hammer 4 rotates under the action of the side drive ring 6, and the block waste is drawn in through the side guide bar 413 structure, and the waste block is crushed in conjunction with the grinding bowl 1 structure. At the same time, the crushed waste fragments are guided by the guide plate 413 structure and guided to the central vibrating hammer 42 position. The fragments are further refined by the up and down movement of the vibrating hammer 42 and the engagement of the grinding disc 411 structure. Then, the refined powder waste is finally ground and refined by the grinding bar 412 on the bottom to reduce the particle size. Finally, after the crushing and grinding is completed, it is discharged through the discharge port 7.
