Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] The present utility model provides a technical solution: As Figures 1 to 4 shown, in this embodiment, a waste recycling device for molecular sieve raw materials includes a fixing frame 1. A discharge port is opened at the top of the fixing frame 1, and molecular sieves can be received at the bottom of the fixing frame 1 through a container. Both ends of the top of the fixing frame 1 are rotatably installed with a rotating rod 2 through bearings. One end of the rotating rod 2 is fixedly installed with a mounting plate 3. Between the two mounting plates 3, screening rods 4 are fixedly installed in an annular array with the central axis of the mounting plate 3 as the axis. The inner bottom end of the fixing frame 1 is rotatably installed with a rotating roller 5 through a bearing. On the outer side of the rotating roller 5, convex blocks 6 are fixedly installed in an annular array with the central axis of the rotating roller 5 as the axis. The convex blocks 6 pass through the gaps between the two screening rods 4. The rotating roller 5 can rotate, and the convex blocks 6 on the rotating roller 5 will sequentially pass through the gaps between the two screening rods 4 to prevent the molecular sieve material from blocking between the two screening rods 4. Inside one of the mounting plates 3, a fixing ring 7 is rotatably installed, and a feed inlet 8 is opened in the middle of the fixing ring 7.

[0022] As Figures 1 to 4 shown, a motor 9 is fixedly installed on one side of the fixing frame 1. The output end of the motor 9 is fixedly installed with a first pulley 10. One end of one of the rotating rods 2 close to the first pulley 10 is fixedly installed with a second pulley 11. A transmission belt 12 is installed between the second pulley 11 and the first pulley 10 for transmission.

[0023] By driving the first pulley 10 to rotate through the motor 9, the rotation of the rotating rod 2 will be driven through the transmission between the second pulley 11 and the first pulley 10 by the transmission belt 12, and then the screening container will be driven to rotate. The smaller molecular sieve particles will be discharged through the gaps between the several screening rods 4 into the inside of the fixing frame 1 and discharged from the bottom of the fixing frame 1, and the larger molecular sieve particles will remain inside the screening container to achieve the screening of the molecular sieve.

[0024] As shown Figures 1 to 4 in the figure, at one end of the rotating rod 2 installed with the second pulley 11 close to the mounting plate 3, a driving gear 13 is fixedly installed, and at the end of the rotating rod 5, a driven gear 14 is fixedly installed. The driven gear 14 is meshed and connected with the driving gear 13.

[0025] During the screening process, the rotation of the rotating rod 5 is driven by the meshing of the driven gear 14 and the driving gear 13, which can be used for cleaning between the two screening rods 4.

[0026] As shown Figures 1 to 4 in the figure, at a position corresponding to the feed port 8 on one side of the fixed ring 7, a blanking plate 15 is fixedly installed. Inside the mounting plate 3 installed with the fixed ring 7, a rotating groove 16 is opened. An integral rotating ring 17 is fixedly installed on the outer side of the fixed ring 7. The rotating ring 17 is rotatably connected with the rotating groove 16. The bottom of the blanking plate 15 is fixedly connected to the end on the fixed frame 1.

[0027] During continuous screening, the position of the fixed ring 7 will be relatively fixed, and the fixed ring 7 and the mounting plate 3 installed with the fixed ring 7 will rotate relative to each other, so that the molecular sieve waste can flow into the screening container from the blanking plate 15 continuously, realizing continuous screening of the molecular sieve waste.

[0028] As shown Figures 1 to 4 in the figure, a mounting hole 18 is opened on the outer ring of the mounting plate 3, and one of the screening rods 4 is slidably installed inside the mounting hole 18.

[0029] By sliding out the movable screening rod 4 from the inside of the mounting hole 18, and then controlling the device to continue operating, under the continuous rotation of the screening container, the large molecular sieve particles left after screening will be discharged from the screening container through the gap here and discharged from the bottom of the fixed frame 1, realizing the recovery of the molecular sieve.

[0030] As shown Figures 1 to 4 in the figure, a baffle 19 is rotatably installed at a position corresponding to the mounting hole 18 on the mounting plate 3 through damping.

[0031] By rotating the baffle 19, the position of the slidable screening rod 4 can be limited and the limit can be cancelled.

[0032] The present utility model provides a waste recycling device for molecular sieve raw materials, and the specific working principle is as follows:

[0033] When the device is in use, molecular sieve waste is filled into the screening container through the feed inlet 8. The first pulley 10 is driven to rotate by the motor 9. The transmission between the second pulley 11 and the first pulley 10 through the transmission belt 12 will drive the rotating rod 2 to rotate, and then drive the screening container to rotate. Smaller molecular sieve particles will be discharged through the gaps between several screening rods 4 into the inside of the fixed frame 1 and discharged from the bottom of the fixed frame 1. Larger molecular sieve particles will remain inside the screening container. During continuous screening, the position of the fixed ring 7 will be relatively fixed, and the fixed ring 7 and the mounting plate 3 on which the fixed ring 7 is installed will rotate relative to each other. The molecular sieve waste can be continuously fed into the screening container from the blanking plate 15 to achieve continuous screening of the molecular sieve waste. During the screening process, the driven gear 14 meshes with the driving gear 13 to drive the rotating rod 5 to rotate. The bumps 6 on the rotating rod 5 will sequentially pass through the gaps between the two screening rods 4 to prevent the molecular sieve material from blocking between the two screening rods 4, which is used for cleaning the device;

[0034] When there is more material left after screening in the screening container, stop the operation of the device, rotate the baffle 19, and slide out a movable screening rod 4 from the inside of the mounting hole 18. Then control the device to continue operating. Under the continuous rotation of the screening container, the large molecular sieve particles left after screening will be discharged from the screening container through this gap and discharged from the bottom of the fixed frame 1 to achieve the recovery of the molecular sieve.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
