[0019] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0020] See also Figure 1-11 The present invention is described in detail below with reference to the accompanying drawings and embodiments: Embodiment 1: like Figure 1-2 As shown, a flexible anti-blocking device for medical waste pyrolysis equipment includes a speed reduction mechanism 1, a connecting pipe 21 and a conveying pipe 22, wherein the speed reduction mechanism 1 includes a driving electrical appliance and a speed reducer, wherein the connecting pipe 21 is fixedly installed on the right side of the speed reducer and sleeved on the outer side of the output shaft of the speed reducer, and a screw conveying shaft 6 is coaxially fixedly installed on the outer end of the output shaft of the speed reducer, and the screw conveying shaft 6 is located in the connecting pipe 21 and the conveying pipe 22, and the spiral blades on the screw conveying shaft 6 do not contact the inner wall of the conveying pipe 22 and have a gap, so that the friction generated when the screw conveying shaft 6 rotates is too large, causing damage to the spiral blades. The speed reduction mechanism 1 is a prior art and is not described in detail here; A flexible unloading mechanism 3 is provided between the connecting pipe 21 and the conveying pipe 22. When the screw conveying shaft 6 is inserted into the medical waste residue pile, the feeding end on the right side will be subject to the resistance of the medical waste residue, and the medical waste residue will also be continuously pushed to the feeding end position of the screw conveying shaft 6, generating thrust on the screw conveying shaft 6, the connecting pipe 21 and the conveying pipe 22. At this time, the flexible unloading mechanism 3 can unload part of the resistance and thrust, preventing the screw conveying shaft 6 and the spiral blades on its surface from radial and axial deformation, thereby extending the service life of the screw conveying shaft 6, the connecting pipe 21 and the conveying pipe 22; An auxiliary feeding mechanism 4 is provided at the right end of the conveying pipe 22. When a large number of medical waste particles are located at the feeding end of the conveying pipe 22, blockage may occur. At this time, the auxiliary feeding mechanism 4 can alleviate the feed blockage of the particle waste, so that it can be stably transported through the spiral conveying pipe 22.

[0021] like Figure 4-5 As shown, the flexible unloading mechanism 3 includes a plurality of sliding shafts 31, pressure spring members 32 and sliding bearings 33 which are circumferentially arranged between the connecting pipe 21 and the conveying pipe 22. The pressure spring member 32 is sleeved on the sliding shaft 31, and the sliding bearing 33 is sleeved and installed on the surface of the sliding shaft 31. The sliding shaft 31 bearing can assist the sliding shaft 33 to slide laterally more stably. The above-mentioned sliding shaft 31 bearing is a prior art and will not be described in detail herein.

[0022] like Figure 4-5 As shown, the sliding bearing 33 passes through the right end face of the connecting pipe 21, and the right annular gasket of the pressure spring member 32 is fixedly mounted on the left end face of the sliding bearing 31, and the connecting pipe 21, the sliding bearing 33 and the right annular gasket of the pressure spring member 32 are fixed together by bolts.

[0023] like Figure 4-5 As shown, the right end of the sliding shaft 31 passes through the right end surface of the conveying pipe 22 and is threadedly engaged. After one end of the sliding shaft 31 is installed on the conveying pipe 22, a nut is subsequently used to strengthen the fastening state of the sliding shaft 31 and the conveying pipe 22.

[0024] like Figure 4-5 As shown, a bolt member 311 is threadedly provided on the left end of the sliding shaft 31 . After the right end of the sliding shaft 31 is fixed, the bolt member 311 is used to fix the left end annular gasket of the pressure spring member 32 and the sliding shaft 31 together.

[0025] like Figure 4-5 As shown, a circular fixing plate 34 is provided between the delivery pipe 22 and the connecting pipe 21 , and a plurality of sliding shafts 31 all pass through the fixing plate 34 and are fixed thereto.

[0026] like Figure 1 , Figure 6 As shown, a circular sealing plate 222 is fixedly provided at the left end opening of the conveying pipe 22, and a discharge port 23 is opened on the lower surface of the conveying pipe 22 near the right side of the sealing plate 222, and an auxiliary discharge mechanism 5 is provided at the position of the discharge port 23.

[0027] like Figure 2 As shown, an exhaust pipe 221 communicating with the inner cavity is fixedly installed on the upper surface of the delivery pipe 22. The exhaust pipe 221 is used to naturally discharge the gas in the delivery pipe 22 out of the delivery pipe and then collect it centrally.

[0028] like Figure 4-5 As shown, a guide shaft 61, a spacer sleeve 63, and a pressure cover 64 are sleeved on the spiral conveying shaft 6 on the left side of the sealing plate 222 to prevent the spiral conveying shaft 6 from being radially deformed by external force. The inner ring of the guide shaft 61 is provided with multiple grooves, and a sealing ring 62 is installed in the groove. The right end of the guide shaft 61 is fixed to the sealing plate 222, and the guide shaft 61 passes through the middle of the fixed plate 34 and is fixed thereto. The spiral conveying shaft 6 can rotate circumferentially on the inner ring of the guide shaft 61, and the guide shaft 61 can also slide axially on the surface of the spiral conveying shaft 6.

[0029] like Figure 13-14 As shown, in order to enhance the use effect of the screw conveying shaft 6, a compensation shaft 66 can be arranged between the screw conveying shaft 6 and the reducer. The compensation shaft 66 replaces the screw conveying shaft 6 and is fixed to the output shaft of the reducer. A sliding frame 662 is fixedly arranged at the right end of the compensation shaft 66. A plurality of supporting shafts 663 are fixedly arranged in a circle inside the sliding frame 662, and a cover plate 665 is installed on the left side of the sliding frame 662. At this time, the compensation shaft 66 is located in the connecting pipe 21, and the plate surface at the left end of the screw conveying shaft 6 slides. In the sliding frame 662, the support shaft 663 passes through the plate surface at the right end of the spiral conveying shaft 6 and slides together. A support spring 664 is installed in the sliding frame 662 and is sleeved on the surface of the support shaft 663. The two ends of the support spring 664 are respectively in contact with the inner wall of the sliding frame 662 and the inner surface of the cover plate 665, and a sliding cavity 661 is opened on the right end surface of the compensation shaft 66. The shaft portion at the left end of the spiral conveying shaft 6 slides in the sliding cavity 661 to ensure the stability of the spiral conveying shaft 6 when it moves axially.

[0030] Specifically, when the screw conveyor shaft 6 is inserted into the medical waste residue pile, the feed end on the right side will be subject to resistance from the medical waste residue. At the same time, the medical waste residue will continue to be pushed to the feed end position of the screw conveyor shaft 6, generating thrust on the screw conveyor shaft 6. At this time, the support spring 664 can remove part of the resistance and thrust.

[0031] Furthermore, the spiral conveying shaft 6 conveys the particulate material on the right side in the conveying pipe 22. When the material reaches the position of the discharge port 23, a part of the material may not be transported through the discharge port 23 in time. As the material continues to enter, a thrust is applied to the sealing plate 222. If the thrust is not handled at this time, it will affect the spiral blades on the surface of the spiral conveying shaft 6. In this embodiment, the thrust will push the sealing plate 222 and the conveying pipe 22 together with the sliding shaft 31 and the fixed plate 34 to move laterally to the left, and cooperate with the pressure spring member 32 to offset this part of the thrust, thereby avoiding radial and axial deformation of the spiral conveying shaft 6 and the spiral blades on its surface, thereby extending the service life of the spiral conveying shaft 6.

[0032] like Figure 7-11 As shown, the auxiliary feeding mechanism 4 includes a feeding pipe 41, a connecting plate 42, a stepped rotating ring 47 and an annular connecting head 43. The left end of the feed pipe 41 is fixedly connected to the right end of the conveying pipe 22 by bolts, and the connecting plate 42 is fixedly arranged at the right end of the feed pipe 41. An annular groove 421 is opened on the right side surface of the connecting plate 42, and a driven gear 46 is rotatably arranged in the annular groove 421. A driving gear 412 is meshed above the driven gear 46, and a driving motor 411 is fixedly installed on the left side surface of the connecting plate 42. The output shaft of the driving motor 411 passes through the connecting plate 42 and is rotatably matched. The output shaft of the driving motor 411 is fixed to the driving gear 412. The above-mentioned driving motor 411 is a prior art and is not described in detail here.

[0033] Specifically, the driving motor 411 drives the driving gear 412 to rotate, thereby driving the driven gear 46 to rotate.

[0034] like Figure 7-11 As shown, a cover plate 422 is fixedly installed on the outer side of the connecting plate 42 by bolts to seal the annular groove 421 to prevent material particles from entering the annular groove 421 and affecting the rotation of the gear.

[0035] like Figure 7-11As shown, an annular groove three 461 is provided on the outer side surface of the driven gear 46, and the rotating ring 47 is axially slidably arranged in the annular groove three 461, and a plurality of fixed shafts 462 are fixedly arranged along the circumference of the annular groove three 461, and the fixed shaft 462 penetrates the rotating ring 47 and slides axially, and a pressure spring two 471 is sleeved on the outer end of the fixed shaft 462, and the right end of the pressure spring two 471 is fixed to the surface of the rotating ring 47, and the left end of the pressure spring two 471 abuts against the inner wall of the annular groove three 461, and a cover plate three 463 is provided on the outer side of the annular groove three 461, and the cover plate three 463 is fixed to the driven gear 46 by bolts, so as to seal the annular groove three 461 and limit the rotating ring 47 at the same time.

[0036] like Figure 7-11 As shown, the inner ring diameter of the driven gear 46 is the same as the inner ring diameter of the feed pipe 41, and a plurality of spiral bars 464 are fixedly arranged in a ring shape on the inner ring of the driven gear 46, and the spiral bars 464 can stir the material to prevent it from being blocked at the feed port.

[0037] like Figure 7-11 As shown, the connecting head 43 is arranged on the right side of the rotating ring 47, and an annular groove 432 is opened on the right side surface of the connecting head 43. A conical top head 44 is slidably arranged in the annular groove 432. A plurality of connecting shafts 441 are fixedly arranged on the left end surface of the top head 44 in a circular shape. A pressure spring 442 is provided on the outer sleeve of the connecting shaft 441. The left end of the pressure spring 442 is fixed to the top head 44, and the right end abuts against the inner wall of the annular groove 432. A cover plate 431 is arranged on the outer side of the annular groove 432. The cover plate 431 is fixed to the connecting head 43 by bolts, and is used to seal the annular groove 432 and limit the top head 44 at the same time.

[0038] like Figure 7-11 As shown, the connecting shaft 441 passes through the annular groove 461 and is slidably fitted. A plurality of spiral rods 45 are fixedly arranged in a ring shape between the connecting shaft 441 and the rotating ring 47. The spiral rods 45 can stir the material at the feed port of the feed pipe 41 to prevent the material from being blocked.

[0039] like Figure 7-11 As shown, a rotating bearing 433 is fixedly provided on the inner ring of the connecting head 43, and the right end of the screw conveying shaft 6 is fixed to the inner ring of the rotating bearing 433. The rotation of the screw conveying shaft 6 is not affected by the rotation of the connecting head 43. The above-mentioned rotating bearing 433 is a prior art and will not be described in detail here.

[0040] Specifically, experiments have shown that the pyrolysis residue formed after low-temperature pyrolysis of medical waste is in the form of particles or small blocks. The right end of the feed pipe 41 is inserted into the pyrolysis residue. At this time, the spiral conveying shaft 6 is driven by the reduction mechanism 1 to convey the material. At the same time, the drive motor 411 will drive the driven gear 46 to rotate intermittently in the reverse or forward direction. At this time, the rotation of several spiral rods 45 can assist the spiral conveying shaft 6 in conveying the material, and can stir the accumulated material, effectively avoiding blockage. When there is too much external material, a lateral thrust will be applied to the components in the auxiliary feeding mechanism 4 during the insertion process. At this time, the pressure spring 1 442 and the pressure spring 2 471 will partially offset the lateral thrust to increase the service life of the components in the auxiliary feeding mechanism 4.

[0041] Furthermore, when the drive motor 411 rotates forward, it is in the same direction as the rotation direction of the screw conveyor shaft 6, which can assist in feeding. When the drive motor 411 rotates reversely, it is in the opposite direction to the rotation direction of the screw conveyor shaft 6, which can break up the medical waste residues accumulated on the outside of the screw conveyor shaft 6 to avoid long-term accumulation and blockage at the feed port.

[0042] like Figure 6 As shown, the auxiliary discharging mechanism 5 includes a discharging frame 51, a spiral discharging shaft 53 and a protective frame 52. The discharging frame 51 is fixedly arranged at the discharge port 23 of the conveying pipe 22. The spiral discharging shaft 53 is located in the discharging frame 51, and its lower end is rotatably matched with the discharging frame 51. The lower end of the discharging frame 51 is provided with an outlet communicating with the outside world. The protective frame 52 is arranged on the surface of the spiral conveying shaft 6. The protective frame 52 can also slide on the surface of the spiral conveying shaft 6 without affecting the rotation of the spiral conveying shaft 6. An L-shaped plate is symmetrically fixedly arranged between the outer side surface of the protective frame 52 and the sealing plate 222 to fix the position of the protective frame 52.

[0043] like Figure 6 As shown, a bevel gear 2 65 is fixedly provided on the surface of the spiral conveying shaft 6 located in the protective frame 52, and a bevel gear 1 531 meshing with the bevel gear 2 65 is fixedly provided on the upper end of the spiral discharge shaft 53. The protective frame 52 is used to prevent the material transported laterally by the spiral conveying shaft 6 from affecting the meshing of the bevel gear 1 531 and the bevel gear 2 65. The rotation of the spiral discharge shaft 53 is driven by the rotation of the spiral conveying shaft 6, thereby assisting the discharge of materials at the discharge port 23 to reduce the accumulation of materials at the discharge port 23.

[0044] like Figure 7As shown, a slide groove 523 is provided on the lower end surface of the protective frame 52, and a slider 521 is slidably arranged in the slide groove 523. Both sides of the slider 521 have extension sections so that the slide groove 523 is always closed during the sliding process. This setting method is a conventional method and is not drawn in detail here. The function of this setting method is mainly to prevent medical waste from entering the protective frame 52. A bearing 522 is fixedly arranged in the slider 521, and the inner ring of the bearing 522 is fixed to the upper shaft neck of the spiral discharge shaft 53. When the conveying pipeline 22 is driven by the sealing plate 222 and moves laterally, the protective frame 52 will also move accordingly. At this time, the spiral discharge shaft 53 will not be affected by the movement of the protective frame 52, and the bevel gear 1 531 and the bevel gear 2 65 will not touch the inner wall of the protective frame 52 after the movement.

[0045] Embodiment 2: Based on the first embodiment, a cleaning sleeve 24 can be installed in the conveying pipe 22. The cleaning sleeve 24 is used to rotate and clean the inner wall of the conveying pipe 22 to prevent particulate materials from sticking to the inner wall of the conveying pipe 22 and affecting the transportation effect.

[0046] like Figure 6 As shown, the cleaning sleeve 24 includes a plurality of ring rods 241, which can rotate in the conveying pipe 22, and a strip rod 242 is symmetrically fixedly connected between every two ring rods 241, the strip rod 242 contacts the inner wall of the conveying pipe 22, and neither the ring rod 241 nor the strip rod 242 contacts the spiral blades on the spiral conveying shaft 6.

[0047] like Figure 6 As shown, a connecting rod 243 is fixedly provided on the leftmost ring rod 241, and the connecting rod 243 is fixedly sleeved on the surface of the spiral conveying shaft 6. The rotation of the spiral conveying shaft 6 drives the cleaning sleeve 24 to rotate, so as to clean the inner wall of the conveying pipe 22 in time. At the same time, the spiral conveying of the spiral conveying shaft 6 can effectively avoid congestion of medical waste in the conveying pipe 22.

[0048] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
