Description

Technical Field

[0001] The utility model relates to the technical field of rare earth polishing powder, in particular to a multi-stage filtering and recovery device for waste materials in rare earth polishing powder. Background Art

[0002] Rare earth polishing powder refers to a powder of mixed light rare earth oxides with cerium oxide as the main component, which is used to improve the surface finish of products or parts. It has the advantages of fine particle size, good chemical activity, strong grinding ability and long service life. It is widely used in the polishing of optical glass parts, TV picture tube glass shells, eyeglass lenses, flat glass, oscilloscopes and organic glass products. In order to avoid the waste contained in it from polluting the environment, it needs to be processed through a multi-stage filtration and recovery device.

[0003] At present, when using a filtering and recycling device, there is a lack of a circulating filtering and conveying mechanism. Usually, when performing multi-stage filtering processing on the waste materials in the rare earth polishing powder, a larger volume is required to achieve multi-stage filtration of the waste materials, which easily increases the floor space and use cost, and the filtered waste materials are difficult to achieve the screening effect, resulting in the flexibility of the device being relatively general. Therefore, a multi-stage filtering and recycling device for the waste materials in the rare earth polishing powder is proposed, so as to increase the circulating filtering and conveying mechanism, and utilize the methods of flipping, displacement, and multiple screening to perform multi-stage filtering processing on the waste materials in the rare earth polishing powder. It can not only reduce the volume of the device and the space occupied, but also realize multiple screening of the waste materials, improve the subsequent recovery quality, and thus improve the use effect.

[0007] By adopting the above technical solution, it is convenient to add a circulating filtration and screening mechanism, and use the methods of flipping, displacement, and multiple filtration to perform multiple, repeated, and cyclic filtration on the rare earth polishing powder, thereby improving the filtration and recovery quality of the waste material. At the same time, it can also play an auxiliary conveying and screening role, making it more reasonable and reliable to use.

[0008] Specifically, the limiting assembly includes a circular frame, and the circular frame is connected to the feeding hopper by bolts. The inner side of the circular frame is rotatably connected to a clamping plate, both ends of the clamping plate are connected to a rotating shaft by bolts, and the clamping plate is rotatably connected to the circular frame through the rotating shaft.

[0009] By adopting the above technical solution, it is convenient to add an auxiliary clamping and limiting mechanism, and use rotation to limit the bag opening, thereby reducing the gap between the feeding hopper and the bag opening, which is beneficial to reducing the generation of dust and improving resource utilization.

[0010] Specifically, the surface of the shell is connected to the stepping motor via bolts, and the stepping motor is connected to the rotating roller via a driving shaft. A waste discharge port is opened on one side of the bottom of the shell.

[0011] By adopting the above technical solution, it is easy to drive the rotating roller to rotate, thereby driving the rare earth polishing powder and its waste to perform flipping, filtering and screening actions.

[0016] Beneficial effects of the utility model:

[0017] (1) The utility model is a multi-stage filtering and recovery device for waste materials in rare earth polishing powder. By providing a shell, a filter chamber, a rotating roller, a filter plate and an inclined trough, an auxiliary circulation filtering and conveying mechanism can be added.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] In order to facilitate multi-stage filtration of waste materials in rare earth polishing powder and improve the subsequent recycling quality, thus improving the use effect, such as Figure 1-3 As shown, the utility model is a multi-stage filtering and recovery device for waste materials in rare earth polishing powder, comprising a housing 1, a filter cavity 2 and a material turning assembly 3. The housing 1 is provided with filter cavities 2 at equal intervals, and the filter cavities 2 are all rotatably connected to the material turning assembly 3. The top of the housing 1 is connected to a feeding hopper 4 by bolts, and the top of the feeding hopper 4 is provided with a limit assembly 5.

[0027] The turning assembly 3 includes a rotating roller 301 , the periphery of the rotating roller 301 is connected to a filter plate 302 via bolts, the filter plate 302 includes filter holes 303 , an inclined groove 101 is provided between the filter chambers 2 in the shell 1 , and the filter chambers 2 are connected to each other via the inclined groove 101 .

[0028] During use, the shell 1, the filter chamber 2, the rotating roller 301, the filter plate 302, the filter hole 303 and the chute 101 are used to facilitate the addition of a circulating filtration and screening mechanism. The rare earth polishing powder is filtered multiple times, repeatedly and cyclically by means of flipping, displacement and multiple filtration, thereby improving the filtering and recycling quality of the waste material. At the same time, it can also play an auxiliary role in conveying and screening, making it more reasonable and reliable to use.

[0029] In order to improve resource utilization, for example, Figure 1 、 Figure 4 As shown, the present invention also includes that the limiting assembly 5 includes a circular frame 501, and the circular frame 501 is connected to the feeding hopper 4 by bolts, the inner side of the circular frame 501 is rotatably connected to a splint 502, both ends of the splint 502 are connected to a rotating shaft 503 by bolts, and the splint 502 is rotatably connected to the circular frame 501 through the rotating shaft 503.

[0030] When in use, the auxiliary clamping and limiting mechanism is added through the circular frame 501, the splint 502, and the rotating shaft 503, and the bag opening is limited by rotation, thereby reducing the gap between the feeding hopper 4 and the bag opening, which is beneficial to reducing the generation of dust and improving resource utilization.

[0031] For example, Figure 1 、 Figure 2 As shown, the present invention further includes that the surface of the shell 1 is connected to the stepper motor 6 via bolts, and the stepper motor 6 is connected to the rotating roller 301 via a driving shaft, and a waste outlet 102 is opened on one side of the bottom of the shell 1.

[0032] When in use, the stepping motor 6 drives the rotating roller 301 to rotate, thereby driving the rare earth polishing powder and its waste to perform flipping, filtering and screening.

[0033] For example, Figure 4 As shown, the present invention further includes that a coil spring 504 is sleeved on the outer periphery of the rotating shaft 503 , and one end of the coil spring 504 is connected to the rotating shaft 503 by welding, and the other end of the coil spring 504 is connected to the circular frame 501 through a slot.

[0034] When in use, the coil spring 504 utilizes elastic deformation to drive the rotating shaft 503 and the clamping plate 502 to flip outwards to perform a clamping action.

[0035] For example, Figure 2 As shown, the present invention further includes that a discharge port 7 is provided at the bottom of the shell 1 , and a sieve plate 701 is connected to the discharge port 7 by bolts.

[0036] When in use, the sieve plate 701 facilitates filtering of waste materials before discharge.

[0037] When the utility model is in use, the operator first places the bagging mouth filled with rare earth polishing powder into the circular frame 501, and uses the elastic deformation of the coil spring 504 to drive the rotating shaft 503 and the clamping plate 502 to rotate outward, so as to clamp and limit the bag opening. In the process of feeding the material into the shell 1 through the feeding hopper 4, the generation of dust can be greatly reduced, which can not only reduce environmental pollution, but also improve the utilization rate of rare earth polishing powder and reduce resource waste. The utility model has a simple structure, is easy to operate, and is more reasonable and reliable to use.

[0038] After the rare earth polishing powder enters the filter chamber 2 in the shell 1, the stepper motor 6 is manually turned on to drive the rotating roller 301 to drive the filter plate 302 to flip, and the fallen rare earth polishing powder is filtered through the filter holes 303 of the filter plate 302, wherein the screened waste is intercepted on the surface of the filter plate 302, and enters the adjacent filter chamber 2 from the inclined slot 101 through the flipping of the filter plate 302, thereby realizing multi-stage, repeated, and cyclic filtration treatment. At the same time, the setting of filter holes 303 of different sizes can play an auxiliary screening effect on the waste. Finally, the waste is sent out from the corresponding discharge port 7 in turn to complete the screening and recovery. The overall structure is simple and easy to operate, and it can also improve the filtering and recovery quality of the waste, and has high practical value.

[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
