DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] like Figure 1-2 As shown, a municipal sludge treatment screen breaking machine provided by one embodiment of the present invention includes a machine base 14 and also includes:

[0033] A screen drum 5, wherein an end seat 3 is fixed at both ends of the screen drum 5, and the ends of the two end seats 3 away from the screen drum 5 are respectively connected with a miscellaneous pipe 1 and a feed pipe 2 25, and the miscellaneous pipe 1 and the feed pipe 2 25 are respectively rotatably mounted with a support 2 and a support 2 12, and the inner side of the screen drum 5 is circumferentially distributed with a plurality of crushing shafts 8, and a plurality of groups of crushing components are fixed on the crushing shaft 8, and the two ends of the crushing shaft 8 are correspondingly connected to the two end seats 3 for rotation, and the side close to the support 1 2 and the support 2 12 is fixed with a support cylinder 23, and a gear ring 24 is fixed on the support cylinder 23, and the two ends of the crushing shaft 8 are respectively fixed with a gear 1 22 meshingly connected with the two gear rings 24;

[0034] A driving assembly, the driving assembly is mounted on the support 1 2 or the support 2 12, and the driving assembly is used to drive the integral rotation of the impurity outlet pipe 1, the end seat 3, the screen drum 5 and the feed pipe 2 25;

[0035] The impurity removal component is installed on the machine base 14, and the impurity removal component is also connected to the support 1 2 and the support 2 12. The impurity removal component is used to support the entirety of the impurity outlet pipe 1, the end seat 3, the screen drum 5, the feed pipe 25, the support 1 2 and the support 2 12. The impurity removal component is also used to control the inclination of the screen drum 5, so as to discharge impurities through the impurity outlet pipe 1.

[0036] In the embodiment of the present invention, the sludge is added into the inner cavity of the screen drum 5 through the second feed pipe 25. The driving assembly drives the whole body composed of the outlet pipe 1, the end seat 3, the screen drum 5 and the second feed pipe 25 to rotate. During this rotation process, the sludge is fully turned over in the screen drum 5, so that it can be effectively screened out through the screen holes of the screen drum 5.

[0037] The clever coordination of the gear 1 22, the support cylinder 23 and the gear ring 2 24 enables the gear 1 22 to smoothly rotate along the surface of the gear ring 2 24 when the crushing shaft 8 rotates in the screen cylinder 5, thereby driving the rotation of the crushing assembly. This design enables the crushing assembly to efficiently crush the sludge in the screen cylinder 5, greatly accelerating the process of sludge being screened out of the screen cylinder 5.

[0038] In addition, the setting of the impurity removal component not only has the function of controlling the inclination of the screen drum 5, so as to facilitate the discharge of impurities through the impurity discharge pipe 1; at the same time, in the process of crushing and screening the sludge, the impurity removal component can also control the screen drum 5 to shake. This shaking, combined with the rotation of the crushing component and the rotation of the screen drum 5, can further improve the crushing effect and screening efficiency of the sludge, making the entire sludge treatment process more efficient and smooth.

[0039] like Figure 1-5 As shown, as a preferred embodiment of the present invention, the end seat 3 is a conical structure, and the inner cavity of the screen drum 5 is smoothly connected to the outlet pipe 1 and the feed pipe 25 through two end seats 3, so that the sludge can flow smoothly and the reliability is improved.

[0040] The crushing assembly includes a crushing plate 6, and a plurality of crushing plates 6 are evenly distributed circumferentially on the crushing shaft 8, and one end of the crushing plate 6 away from the crushing shaft 8 is inclined toward the feeding direction, that is, inclined toward the feed pipe 25, and the specific inclination is not limited. This limitation can improve the crushing effect of the sludge and allow the sludge to fully stay in the screen drum 5 and be processed.

[0041] In one embodiment, a plurality of semicircular guide plates 7 are fixed in the screen drum 5, the guide plates 7 are arranged perpendicular to the inner wall of the screen drum 5, two adjacent guide plates 7 are arranged alternately, and the crushing shaft 8 passing through the guide plates 7 is rotatably connected thereto, that is, the crushing shaft 8 can also be stably supported by the guide plates 7. With this definition, when the screen drum 5 is tilted, the guide plates 7 are used for diversion to improve the thoroughness of sludge treatment, and the rotation of the screen drum 5 is used to improve the treatment effect.

[0042] The driving assembly includes a ring gear 1 21, a second gear 26 and a motor 27, wherein a ring gear 1 21 is fixed on one of the end seats 3, and a motor 27 is fixed on the adjacent support 1 2 or support 2 12, and a second gear 26 meshingly connected with the ring gear 1 21 is fixed on the output end of the motor 27. According to this definition, the motor 27 drives the second gear 26 to rotate, thereby driving the ring gear 1 21 and the end seat 3 to rotate, thereby realizing the overall rotation of the screen drum 5.

[0043] Preferably, the support cylinder 23 fixed on the support 1 2 is also rotatably connected to the outlet pipe 1, and the support cylinder 23 fixed on the support 2 12 is also rotatably connected to the feed pipe 2 25, thereby improving the stability of the support cylinder 23 supporting the gear ring 2 24 and the reliability of the rotation of the outlet pipe 1 and the feed pipe 2 25.

[0044] The impurity removal assembly includes a telescopic cylinder 13 and a bracket 19, the lower end of the support 1 2 is hinged with the bracket 19, the lower end of the bracket 19 is fixed to the machine base 14, the lower end of the support 2 12 is hinged with the telescopic cylinder 13, and the lower end of the telescopic cylinder 13 is hinged to the machine base 14. By controlling the telescopic cylinder 13 to extend and retract, the inclination of the screen drum 5 can be adjusted, thereby achieving the desired function.

[0045] In one embodiment, the municipal sludge treatment screening machine also includes a feed assembly, which includes a hopper 9, a feed pipe 10 and a bracket 11. The end of the feed pipe 25 is rotatably connected to the feed pipe 10. The feed pipe 10 adopts an L-shaped structure. The upper end of the vertical portion of the feed pipe 10 is cooperatively connected to the hopper 9. The feed pipe 10 is also connected and fixed to the support 12 through the bracket 11. The bracket 11 can stably support the hopper 9 and the feed pipe 10, so that the sludge added to the hopper 9 can be introduced into the feed pipe 25 through the feed pipe 10, and finally enters the screen cylinder 5.

[0046] In one embodiment, the municipal sludge treatment screening machine also includes a protective material receiving assembly, which includes a protective cylinder 4, a feed shaft 15, a threaded blade 16, a feed cylinder 17 and a discharge pipe 18. The outer side of the screen cylinder 5 is sleeved with a protective cylinder 4, and the two ends of the protective cylinder 4 are rotatably connected to the two end seats 3 respectively. The lower part of the protective cylinder 4 is cooperatively connected with the feed cylinder 17, and the inner cavity of the protective cylinder 4 is connected to the inner cavity of the feed cylinder 17. A feed shaft 15 is provided in the inner cavity of the feed cylinder 17, and the two ends of the feed shaft 15 are rotatably connected to the feed cylinder 17. The output end of the motor 27 is also transmission-connected to the feed shaft 15. A threaded blade 16 is also fixed on the feed shaft 15 in the feed cylinder 17, and a discharge pipe 18 is also provided at the end of the threaded blade 16 in the feeding direction at the bottom of the feed cylinder 17. In order to keep the protection cylinder 4 and the receiving cylinder 17 stable, the two ends of the receiving cylinder 17 are respectively fixed with fixing frames 20, and the fixing frames 20 are correspondingly fixedly connected to the support 1 2 and the support 2 12. Through this definition, the protection cylinder 4 plays a protective role, and the rotation of the screen cylinder 5 will not affect the protection cylinder 4, the receiving cylinder 17, etc. The motor 27 can also drive the feed shaft 15 to rotate, and the sludge screened by the screen cylinder 5 can be transported through the threaded blades 16, and then discharged through the discharge pipe 18; the whole structure also has the function of preventing dust, protecting the surrounding environment from being affected.

[0047] In one embodiment, Figure 3-5As shown, the inner sides of the outlet pipe 1 and the feed pipe 2 25 are respectively installed with a dustproof piece 1 28 and a dustproof piece 29, and the structures of the dustproof piece 1 28 and the dustproof piece 2 29 are the same, and both the dustproof piece 1 28 and the dustproof piece 2 29 include a plurality of fan-shaped spring pieces evenly distributed in the circumferential direction; when there is no external force, the dustproof piece 1 28 is a conical structure with the middle part tilted away from the screen drum 5, and the dustproof piece 2 29 is a conical structure with the middle part tilted toward the screen drum 5; when there is no external force, the plurality of fan-shaped spring pieces abut together and block the inner cavities of the outlet pipe 1 and the feed pipe 2 25. Through the limitation and structural setting of the dustproof piece 1 28 and the dustproof piece 2 29, the dustproof piece 1 plays a role of blocking and dust prevention, and does not affect the passage of materials; when the materials pass through, the materials will push the fan-shaped spring pieces, so as to pass through, and do not affect the feeding and discharging.

[0048] like Figure 6-7 As shown, as a preferred embodiment of the present invention, the municipal sludge treatment screening machine also includes a feeding auxiliary component, which includes a cam 30, a transmission plate 31, a limit cap 32, a spring 33, a guide rod 34, a bearing seat 35, a bulk shaft 36, a sleeve 37, a bulk rod 38 and a slider 40. The cam 30 is fixed on the feed pipe 25, and a transmission plate 31 matching the cam 30 is provided on the lower side of the feed pipe 10 (note that the installation position of the bracket 11 should be adjusted so as not to affect the transmission plate 31, which is not limited). A plurality of guide rods 34 are slidably provided on the transmission plate 31, and the upper ends of the guide rods 34 are fixedly connected to the feed pipe 10, and the lower ends of the guide rods 34 are fixedly provided with a limit cap 32. The guide rods 34 between the feed pipe 10 and the transmission plate 31 are also sleeved with a spring. Spring 33, one end of the spring 33 is fixedly connected to the feed pipe 10, and the other end of the spring 33 is fixedly connected to the transmission plate 31; a bulk shaft 36 is also provided on the inner side of the feed pipe 10, and the bulk shaft 36 is coaxially arranged with the vertical part of the feed pipe 10, and a plurality of bulk rods 38 are circumferentially distributed and fixed on the upper end of the bulk shaft 36, and the bulk rods 38 are arranged to be inclined downward at one end away from the bulk shaft 36, and the bulk shaft 36 is rotatably extended from the bottom wall of the feed pipe 10, and a sleeve 37 is fixed on the outer side of the feed pipe 10 to be slidably and rotatably connected to the bulk shaft 36, and an arc groove 39 is provided on the inner side of the sleeve 37, and a slider 40 slidably connected to the arc groove 39 is also fixed on the bulk shaft 36, and a bearing seat 35 is rotatably installed on the lower end of the bulk shaft 36, and the bearing seat 35 is fixed on the transmission plate 31.

[0049] When in use, with the help of the rotation of the feed pipe 25, the cam 30 can push the transmission plate 31 to move downward, the guide rod 34 can be used to stably guide the transmission plate 31, and the spring 33 can make the transmission plate 31 always close to the cam 30; when the transmission plate 31 drives the bulk shaft 36 to rise and fall, the bulk shaft 36 can rotate by using the matching setting of the arc groove 39 and the slider 40, and the bearing seat 35 can support the rotation of the bulk shaft 36, so that the bulk rod 38 can be lifted and rotated, which is beneficial to break up the sludge, thereby facilitating smooth feeding. At the same time, the inclined structure of the bulk rod 38 reduces the resistance of the bulk rod 38 when it rises, and at the same time, when the bulk rod 38 descends, it can push the sludge downward, thereby improving the effect of auxiliary feeding.

[0050] The present invention provides a sieving machine for municipal sludge treatment, wherein the sludge in the hopper 9 is smoothly introduced into the feed pipe 25 through the feed pipe 10, and finally enters the screen cylinder 5. The driving assembly drives the whole composed of the outlet pipe 1, the end seat 3, the screen cylinder 5 and the feed pipe 25 to rotate, and the sludge is turned inside the screen cylinder 5 and effectively screened out through the screen cylinder 5.

[0051] It is worth mentioning that the clever combination of gear 1 22, support cylinder 23 and gear ring 2 24 enables the crushing shaft 8 to smoothly rotate along the surface of gear ring 2 24 when the screen cylinder 5 rotates, thereby driving the crushing assembly to rotate. This design significantly improves the crushing efficiency of the sludge in the screen cylinder 5, thereby accelerating the sludge screening process.

[0052] In addition, the inclined design of the crushing plate 6 not only improves the crushing effect of the sludge, but also ensures that the sludge can fully stay in the screen drum 5 and be effectively processed.

[0053] The design of the impurity removal component allows the inclination of the screen drum 5 to be adjusted by controlling the extension and contraction of the telescopic cylinder 13. This function not only facilitates the discharge of impurities through the impurity discharge pipe 1, but also the guide plate 7 can play a good role in guiding the flow when the screen drum 5 is tilted, further improving the thoroughness of sludge treatment. At the same time, the impurity removal component can also control the shaking of the screen drum 5 when crushing and screening the sludge, and combined with the crushing component and the rotation of the screen drum 5, significantly improve the crushing and screening effect of the sludge.

[0054] The setting of the protective material receiving assembly further enhances the practicality and environmental protection of the sieve crusher. The protective cylinder 4 plays an effective protective role and does not affect the rotation of the screen cylinder 5. The motor 27 drives the feed shaft 15 to rotate, and the sludge screened by the screen cylinder 5 is transported to the discharge pipe 18 through the threaded blades 16 for discharge. The entire structure also has a dust-proof function, which effectively protects the surrounding environment.

[0055] The design of the dustproof piece 1 28 and the dustproof piece 2 29 is ingenious, which not only plays the role of blocking dust, but also does not affect the passage of materials. When the materials pass through, the fan-shaped spring pieces will be pushed open by the materials, thereby ensuring the smoothness of feeding and the efficiency of discharging.

[0056] Finally, the addition of the feeding auxiliary component further improves the performance of the screen breaker. With the rotation of the feed pipe 25, the cam 30 pushes the transmission plate 31 to move up and down, thereby driving the bulking shaft 36 to move up and down. The lifting and rotating design of the bulking rod 38 allows the sludge to be better broken up and smoothly enter the screen drum 5. At the same time, its inclined structure also reduces the resistance when rising and pushes the sludge when falling, further enhancing the effect of auxiliary feeding.

[0057] The PLC controller disclosed in the prior art can be used to control each component. The model and circuit connection of each component are not specifically limited and can be flexibly set in actual application.

[0058] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
