Detailed Embodiments

[0019] In order to clearly and completely describe the purpose and technical solutions of the present invention and make its advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Please refer to Figures 1 to 12 , the present invention provides a technical solution: a drying and collecting device for nuclear power three-waste treatment.

[0021] Embodiment 1, a drying and collecting device for nuclear power three-waste treatment, comprising: a crushing chamber 8 is provided inside a processing box 2, a motor 3 is fixed on the outer surface of the processing box 2, a driving gear 17 is fixed at the output end of the motor 3, two stirring shafts 5 are movably clamped on the side surface of the driving gear 17, a first stirring blade 14 and a second stirring blade 15 are respectively fixed on the outer surfaces of the two stirring shafts 5, and the first stirring blade 14 and the second stirring blade 15 are located inside the crushing chamber 8. Since the two stirring shafts 5 are symmetrically distributed and the first stirring blade 14 and the second stirring blade 15 are cross-distributed, when the solid waste falls between the two stirring shafts 5 through the through slot 24, the alternating first stirring blade 14 and second stirring blade 15 will crush the solid waste bidirectionally, making the solid waste crushed more completely, thereby avoiding the situation of blocking the filter plate 6.

[0022] A second driving gear 19 and a driven gear 26 are movably arranged inside a transmission chamber 23. A first storage bin 11 and a second storage bin 16 are fixed at the upper end of the driven gear 26. Bottom covers 21 are movably arranged at the lower ends of the first storage bin 11 and the second storage bin 16. A sliding rod 28 is fixed on the side surface of the bottom cover 21. A fixing plate 20 is arranged above the driven gear 26. A slide rail 29 is provided on the upper surface of the fixing plate 20. Since the side of the second driving gear 19 close to the through slot 24 is concave, the sliding rod 28 will move along the slide rail 29 towards the axis of the fixing plate 20, and then the bottom cover 21 will move towards the axis of the fixing plate 20, thereby opening the bottom opening of the storage bin located at the position of the second storage bin 16 and sending the solid waste inside it into the crushing chamber 8. This feeding mechanism realizes the effect of automatic feeding and the effect of intermittent feeding, and avoids the situation of excessive feeding at one time, which increases the crushing difficulty.

[0023] On the basis of the first embodiment, in order to achieve more complete crushing of solid waste, a feed bin 1 is fixed at the upper end of the treatment box 2. Inside the treatment box 2, a material distribution bin 7, a transmission bin 23, and a crushing bin 8 are respectively arranged from top to bottom. On the upper surface of the inner wall of the feed bin 1, a cylinder 9 is fixed. The output end of the cylinder 9 is fixed with a baffle 10. When the smooth part of the second transmission gear 19 corresponds to the passive gear 26, the first storage bin 11 is exactly located below the feed port 22. The cylinder 9 drives the baffle 10 to move upward, so that the solid waste in the feed bin 1 enters the inside of the first storage bin 11 through the feed port 22. When the toothed part of the second transmission gear 19 corresponds to the passive gear 26, the cylinder 9 will drive the baffle 10 to move downward to close the feed port 22. A feed port 22 is opened on the bottom surface of the inner wall of the feed bin 1. The feed port 22 communicates the feed bin 1 and the material distribution bin 7. The baffle 10 corresponds to the feed port 22 and is movably clamped. A through groove 24 is opened on the bottom surface of the inner wall of the material distribution bin 7. The through groove 24 communicates the material distribution bin 7 and the crushing bin 8.

[0024] A driving bevel gear 18 is fixed at the end of the driving gear 17. The stirring shaft 5 is movably inserted through the inner wall of the crushing bin 8. A first transmission gear 13 is fixed at the end of the stirring shaft 5 close to the motor 3. The first transmission gear 13 corresponds to the driving gear 17 and is movably clamped. Starting the motor 3 drives the driving gear 17 to rotate. The rotation of the driving gear 17 will drive the two stirring shafts 5 to rotate through the first transmission gear 13. And the two stirring shafts 5 rotate in opposite directions, which will crush the solid waste bidirectionally.

[0025] A rotating rod 4 is movably arranged on the side surface of the treatment box 2. The rotating rod 4 is located above the motor 3. Transmission bevel gears 12 are fixed at both ends of the motor 3. A driven bevel gear 27 is fixed at the lower end of the second transmission gear 19. Only half of the side surface of the second transmission gear 19 is fixed with teeth. The second transmission gear 19 and the passive gear 26 have the same diameter. The second transmission gear 19 corresponds to the passive gear 26 and is movably clamped. Since only half of the side surface of the second transmission gear 19 has teeth and the second transmission gear 19 and the passive gear 26 have the same diameter, the second transmission gear 19 rotates one circle and only drives the passive gear 26 to rotate half a circle, achieving the effect of automatic feeding and achieving the effect of intermittent feeding, avoiding excessive feeding at one time and increasing the crushing difficulty. The transmission bevel gear 12 fixed at the lower end of the rotating rod 4 corresponds to and is clamped with the driving bevel gear 18. The transmission bevel gear 12 fixed at the upper end of the rotating rod 4 corresponds to and is clamped with the driven bevel gear 27.

[0026] A support frame 25 is fixed on the upper surface of the driven gear 26. The first storage bin 11 and the second storage bin 16 are fixed at both end parts on both sides of the support frame 25. The first storage bin 11 and the second storage bin 16 are symmetrically distributed. The fixing plate 20 is fixed on the surface of the material distribution bin 7. The support frame 25 movably penetrates through the axis of the fixing plate 20. The first storage bin 11 and the second storage bin 16 are exactly the same. The inner wall diameter of the first storage bin 11 is the same as and corresponds to the diameter of the feed inlet 22. The second storage bin 16 corresponds to the through groove 24. This feeding mechanism realizes the effect of automatic feeding and the effect of intermittent feeding, and avoids the difficulty of crushing caused by excessive feeding at one time.

[0027] The side of the slide rail 29 close to the through groove 24 is concave. The sliding rod 28 corresponds to the slide rail 29 and is movably clamped. A positioning block 30 is fixed on the upper surface of the bottom cover 21. A positioning groove 31 is opened at the lower end of the second storage bin 16. The positioning block 30 corresponds to the positioning groove 31 and is movably clamped. Since the side of the second transmission gear 19 close to the through groove 24 is concave, the sliding rod 28 will move along the slide rail 29 towards the axis of the fixing plate 20, and then the bottom cover 21 will move towards the axis of the fixing plate 20, thereby opening the bottom opening of the storage bin at the position of the second storage bin 16 and sending the solid waste inside it into the crushing bin 8. This feeding mechanism realizes the effect of automatic feeding. The two stirring shafts 5 are symmetrically distributed inside the crushing bin 8. The first stirring blades 14 and the second stirring blades 15 are cross-distributed. The central parts of the two stirring shafts 5 correspond to the through groove 24. A filter plate 6 is arranged on the bottom surface of the inner wall of the crushing bin 8.

[0028] During actual use, when it is necessary to crush and collect the dried solid waste, the motor 3 is started to drive the driving gear 17 to rotate. The rotation of the driving gear 17 will drive the two stirring shafts 5 to rotate through the first transmission gear 13, and the two stirring shafts 5 rotate in opposite directions. The rotation of the two stirring shafts 5 will drive the first stirring blades 14 and the second stirring blades 15 to rotate inside the crushing bin 8. Since the two stirring shafts 5 are symmetrically distributed and the first stirring blades 14 and the second stirring blades 15 are cross-distributed, when the solid waste falls between the two stirring shafts 5 through the through groove 24, the alternating first stirring blades 14 and second stirring blades 15 will crush the solid waste in two directions, making the solid waste crushed more completely, thus avoiding the situation of blocking the filter plate 6. Before crushing the solid waste, it is first stored in the feed bin 1. When the crushing assembly is running, the motor 3 will simultaneously drive the rotating rod 4 to rotate through the engagement of the driving bevel gear 18 and the transmission bevel gear 12. The rotating rod 4 will drive the second transmission gear 19 to rotate through the engagement of the transmission bevel gear 12 and the driven bevel gear 27. Since there are only half of the teeth on the side surface of the second transmission gear 19 and the second transmission gear 19 and the driven gear 26 have the same diameter, the second transmission gear 19 will only drive the driven gear 26 to rotate half a turn when it rotates one circle. Therefore, when the smooth part of the second transmission gear 19 corresponds to the driven gear 26, the first storage bin 11 is exactly located below the feed inlet 22. The air cylinder 9 drives the baffle 10 to move upward, enabling the solid waste in the feed bin 1 to enter the interior of the first storage bin 11 through the feed inlet 22. When the toothed part of the second transmission gear 19 corresponds to the driven gear 26, the air cylinder 9 drives the baffle 10 to move downward to close the feed inlet 22. Meanwhile, the teeth on the outer surface of the second transmission gear 19 drive the driven gear 26 to rotate, and the first storage bin 11 rotates half a circle to be located at the position of the second storage bin 16 in the attached drawing, so as to pour the solid waste stored inside it into the crushing bin 8 through the through slot 24; When the first storage bin 11 rotates towards the position of the second storage bin 16, the sliding rod 28 first makes a circular motion centered on the axis of the fixed plate 20 inside the slide rail 29. When the first storage bin 11 is about to reach the position of the second storage bin 16, since the side of the second transmission gear 19 near the through slot 24 is concave, the sliding rod 28 will move along the slide rail 29 towards the axis of the fixed plate 20, and then the bottom cover 21 will move towards the axis of the fixed plate 20, thus opening the bottom opening of the storage bin at the position of the second storage bin 16 and sending the solid waste inside it into the crushing bin 8. This feeding mechanism achieves the effect of automatic feeding and the effect of intermittent feeding, avoiding excessive feeding at one time and increasing the crushing difficulty.

[0029] Although the above describes the illustrative specific embodiments of the present application for the convenience of those skilled in the art to understand the present application, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present application defined and determined by the appended claims, all applications and creations using the concept of the present application are within the scope of protection.
