Description

Technical Field

[0001] This utility model belongs to the field of environmental protection and comprehensive resource utilization technology, specifically relating to a sludge feeding anti-collision falling cylinder. Background Technology

[0002] In today's society, with the acceleration of urbanization and rapid industrial development, the amount of sewage sludge generated is increasing daily. Sludge comes from a wide range of sources. Municipal wastewater treatment plants generate large amounts of municipal sludge during the purification of urban sewage; various industrial enterprises, such as chemical, printing and dyeing, and papermaking industries, also generate industrial sludge of varying properties when treating industrial wastewater. If this sludge is not effectively treated, it will lead to a series of serious environmental problems.

[0003] Effective sludge treatment is of great significance to environmental protection. It is not only a key measure to reduce environmental pollution and maintain ecological balance, but also an inevitable requirement for realizing resource recycling and promoting sustainable development. In the past, many sludge treatment equipment adopted a relatively simple and direct feeding method, that is, allowing sludge to fall freely into the treatment equipment through a common drop cylinder. Due to the fluidity and irregularity of sludge itself, it is difficult to accurately control its speed and direction during the fall. At the same time, the drop cylinders of existing technologies are all designed as a whole and cannot be disassembled in sections. When a single section needs maintenance, the entire drop cylinder needs maintenance, resulting in waste of resources. Therefore, a sludge feeding anti-collision drop cylinder is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to connect the cascading cylinder in layers for quick disassembly and how to prevent collisions during feeding. In view of the shortcomings of the prior art, this utility model provides a sludge feeding anti-collision cascading cylinder.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sludge feeding anti-collision falling cylinder, including a buffer cylinder and a first fixing ring. The buffer cylinder is provided with a layered quick-release connection mechanism on its exterior and a diversion mechanism on its interior. The layered quick-release connection mechanism includes a first fixing block, which is fixedly connected to the surface of the first fixing ring. The first fixing block is provided with a bolt with one end extending to its exterior. The surface of the buffer cylinder is provided with a second fixing block. The end of the bolt away from the first fixing block passes through to the exterior of the second fixing block. A nut is threaded onto the surface of the bolt.

[0006] Furthermore, the diversion mechanism includes a fixed column located inside the buffer cylinder. The surface of the fixed column is provided with multiple guide plates, and the ends of the multiple guide plates away from the fixed column are fixedly connected to the inner wall of the buffer cylinder.

[0007] Furthermore, it also includes a feed cylinder, which is disposed on the surface of the first fixed ring and extends into its interior at one end, thereby driving the first fixed ring to be disposed at one end of the buffer cylinder. The end of the feed cylinder away from the first fixed ring is connected to a feeding cylinder, and the other end of the buffer cylinder is provided with a second fixed ring. One end of the second fixed ring is connected to a conical cylinder, and the other end of the conical cylinder is connected to a discharge pipe.

[0008] Furthermore, there are two layered quick-release connecting mechanisms, which are located at both ends of the buffer cylinder and are used to connect the feed cylinder and the conical cylinder, respectively.

[0009] Furthermore, both the first fixing block and the second fixing block are provided with through holes, and the size of the two through holes is adapted to the size of the bolt.

[0010] Furthermore, the inner wall of the buffer cylinder is provided with a rubber layer, the size of which is adapted to the size of the buffer cylinder.

[0011] Furthermore, a sealing ring is provided between the first fixing ring and the buffer cylinder, and a sealing ring is provided between the second fixing ring and the buffer cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By adopting a layered quick-release connection mechanism, the drop cylinder can be quickly disassembled and connected in sections. At the same time, sealing rings are used between each section to prevent leakage. There is no need to disconnect the upstream and downstream pipes during disassembly, which allows the drop cylinder to be maintained section by section, saving time and resources and improving the practicality and convenience of the drop cylinder.

[0013] 2. By adopting a diversion mechanism, the internal flow of the buffer cylinder can be diverted, thereby reducing the collision inside the buffer cylinder and making it less prone to clogging. In addition, a rubber layer is set on the inner wall of the buffer cylinder to further reduce the collision of sludge inside the buffer cylinder. Attached Figure Description

[0017] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0018] In this embodiment, see Figure 1-4 A sludge feeding anti-collision falling cylinder includes a buffer cylinder 1 and a first fixing ring 2. The buffer cylinder 1 is provided with a layered quick-release connection mechanism on the outside and a diversion mechanism on the inside. The layered quick-release connection mechanism includes a first fixing block 8, which is fixedly connected to the surface of the first fixing ring 2. The first fixing block 8 is provided with a bolt 9 extending to the outside of it at one end. The surface of the buffer cylinder 1 is provided with a second fixing block 10. The end of the bolt 9 away from the first fixing block 8 passes through to the outside of the second fixing block 10. A nut 11 is threadedly connected to the surface of the bolt 9.

[0019] It should be noted that the bolt 9 has threads on its surface and the nut 11 has threads on its inner wall. The threads on the surface of the bolt 9 and the threads on the inner wall of the nut 11 are matched in size. The purpose of this is to allow the lowering cylinder to be disassembled in sections, so that only one section needs to be maintained during maintenance, thus shortening the maintenance time.

[0020] Technical effect: By using the cooperation of the first fixing block 8, bolt 9, second fixing block 10 and nut 11, the feeding cylinder can be disassembled in sections for quick disassembly. This allows the feeding cylinder to be disassembled when a single section needs maintenance, thus eliminating the need to maintain the entire feeding cylinder, reducing the maintenance time of the feeding cylinder, saving materials used during maintenance, and indirectly saving resources.

[0021] Optionally, see Figure 2-3 The diversion mechanism includes a fixed column 12, which is located inside the buffer cylinder 1. The surface of the fixed column 12 is provided with multiple guide plates 13, and the ends of the multiple guide plates 13 away from the fixed column 12 are fixedly connected to the inner wall of the buffer cylinder 1.

[0022] It should be noted that the guide plate 13 divides the interior of the buffer cylinder 1 into multiple spaces, thus preventing congestion inside the buffer cylinder 1 during sludge fall. This also allows the sludge to fall evenly within the buffer cylinder 1, preventing it from colliding with the inner wall and improving the efficiency of sludge fall. It also reduces collisions with the internal equipment of the falling cylinder.

[0023] Technical effect: By using the combination of fixed column 12 and multiple guide plates 13, the flow inside the buffer cylinder 1 can be diverted, so that the sludge will not accumulate inside the buffer cylinder 1, thereby avoiding the collision of sludge with the inside of the buffer cylinder 1.

[0024] Optionally, it also includes a feed cylinder 3, which is disposed on the surface of the first fixed ring 2 and extends into its interior at one end, thereby driving the first fixed ring 2 to be disposed at one end of the buffer cylinder 1. The end of the feed cylinder 3 away from the first fixed ring 2 is connected to a feeding cylinder 4, and the other end of the buffer cylinder 1 is provided with a second fixed ring 5. One end of the second fixed ring 5 is connected to a conical cylinder 6, and the other end of the conical cylinder 6 is connected to a discharge pipe 7.

[0025] The feeding cylinder 4 is funnel-shaped when viewed from the front. Its purpose is to allow sludge to enter the interior of the buffer cylinder 1 quickly, so that the sludge inside the buffer cylinder 1 falls evenly. Meanwhile, the conical cylinder 6 is designed to allow sludge to flow smoothly out of the interior of the buffer cylinder 1, thereby improving the efficiency of sludge discharge and preventing sludge from accumulating inside the conical cylinder 6.

[0026] Optionally, there are two layered quick-release connection mechanisms, which are located at both ends of the buffer cylinder 1 and are used to connect the feed cylinder 3 and the conical cylinder 6, respectively.

[0027] In addition, the purpose of setting up multiple layered quick-release connection mechanisms is to allow the discharge pipe 7 and the feed cylinder 3 to be disassembled and maintained separately, so that when a certain section needs maintenance, it can be disassembled. At this time, it is not necessary to maintain the entire discharge cylinder, saving resources and improving the efficiency of discharge cylinder maintenance.

[0028] Optionally, both the first fixing block 8 and the second fixing block 10 are provided with through holes. The size of the two through holes is adapted to the size of the bolt 9. Their function is to facilitate the installation of the feed cylinder 3 and the discharge pipe 7, thereby making the feed cylinder 3 and the discharge pipe 7 more stable after installation and improving the stability of the installation of the feed cylinder 3 and the discharge pipe 7.

[0029] Optionally, the inner wall of the buffer cylinder 1 is provided with a rubber layer, the size of which is adapted to the size of the buffer cylinder 1. Its function is to reduce the impact force of the sludge colliding with the inner wall of the falling cylinder or the internal components of the equipment during the falling process by using the elasticity of the buffer material, thereby reducing the impact of the sludge on the inner wall of the buffer cylinder 1 to a certain extent.

[0030] Optionally, a sealing ring is provided between the first fixing ring 2 and the buffer cylinder 1, and a sealing ring is provided between the second fixing ring 5 and the buffer cylinder 1, which can achieve the purpose of sealing the entire falling cylinder, so that the sludge will not leak out when the falling cylinder is in use, further improving the sealing performance of the falling cylinder installation, and at the same time, it will not affect the use of the layered quick-release connection mechanism.

[0031] Working principle: When a section of the falling cylinder needs to be disassembled for maintenance, the nut 11 and bolt 9 need to be removed first to separate them. Then, the bolt 9 is removed from the inside of the second fixing block 10, and the section to be disassembled is then removed for maintenance. When anti-collision treatment is carried out on the falling sludge, the sludge is first fed from the feeding cylinder 4 through the feeding cylinder 3 into the inside of the buffer cylinder 1. Then, the sludge falls evenly inside the buffer cylinder through the action of the guide plate 13. Due to the rubber layer, the collision of the sludge with the inner wall of the buffer cylinder 1 is reduced.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
