Description

Technical Field

[0001] This utility model relates to the field of anaerobic digester technology, and in particular to a novel protective structure for the top of a digester. Background Technology

[0002] An anaerobic digester is a closed system used for anaerobic biodegradation. It utilizes anaerobic microorganisms under anaerobic or oxygen-deficient conditions to convert organic waste (such as sewage, garbage, and agricultural waste) into biogas (mainly methane) and other byproducts. This process not only effectively reduces organic pollutants but also provides renewable energy for industrial production. In an anaerobic environment, anaerobic microorganisms decompose organic matter, producing gases such as methane, carbon dioxide, and ammonia, and generating some solid residue.

[0003] In existing technologies, when performing weld maintenance on the top of an anaerobic digester, safety equipment is required. This equipment consists of a hook rope. By attaching the hook rope to the guardrail, when workers move or operate tools, the hook rope will form a strong pull through the fixed support of the guardrail, directly preventing personnel from falling from the top of the digester and avoiding personal injury caused by falls from heights. However, because the guardrail is welded together with vertical and longitudinal objects, when moving it, the vertical objects may obstruct the movement, requiring the hooks to be removed and then hung in another area. At the moment the hooks are removed, the workers are in a state of no direct protection, which makes it inconvenient for the operators to move the guardrail. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] like Figures 1-5As shown, this utility model provides a technical solution: a novel tank top protection structure, including a protection mechanism 1, with an anti-fall mechanism 2 at the top of the protection mechanism 1. The protection mechanism 1 includes a gas-water separation zone 13, with a central column 113 at the top of the gas-water separation zone 13. The top of the gas-water separation zone 13 is fixedly connected to the bottom of the central column 113. A spiral spring 14 is provided on one side of the central column 113, and one end of the spiral spring 14 is fixedly connected to one side of the central column 113. A pull strap 15 is provided on the other end of the spiral spring 14, and one end of the pull strap 15 is fixedly connected to one end of the pull strap 15. An outer ring 16 is provided on the other end of the pull strap 15, and the other end of the pull strap 15 is fixedly connected to the inner side of the outer ring 16. The bottom of the outer ring 16 is fixedly connected to the top of the gas-water separation zone 13. A fixing ring 17 is provided on the inner wall of the outer ring 16, and the inner wall of the outer ring 16 is connected to the fixing ring 17. The inner side is fixedly connected, and a fitting strip 18 is provided on one side of the fixing ring 17. One side of the fixing ring 17 is fixedly connected to one end of the fitting strip 18. A connecting plate 19 is provided at one end of the fitting strip 18. One end of the fitting strip 18 is fixedly connected to the middle of one side of the connecting plate 19. A binding strip 110 is provided at one end of the connecting plate 19. One end of the connecting plate 19 is fixedly connected to one end of the binding strip 110. A limiting wheel 112 is provided at one side of the outer ring 16. One side of the outer ring 16 is rotatably connected to one end of the limiting wheel 112. The outer side of the limiting wheel 112 is rotatably contacted with one side of the fitting strip 18. The bottom end of the gas-liquid separation zone 13 is fixedly connected to the center of the top of the anaerobic tank 11. A guardrail 12 is provided at the edge of the top of the anaerobic tank 11. The edge of the top of the anaerobic tank 11 is fixedly connected to the bottom end of the guardrail 12. The top of the middle column 113 is fixedly connected to the center of the bottom side of the top plate 111.

[0022] In this embodiment, when the novel protective structure of the tank top is in use, a gas-liquid separation zone 13 is automatically installed at the center of the top of the anaerobic tank 11. The gas-liquid separation zone 13 is cylindrical, and a central column 113 is fixed at the top of the gas-liquid separation zone 13. The central column 113 is located at the center of the gas-liquid separation zone 13, and a spiral spring 14 is installed on the outside of the central column 113. The other end of the spiral spring 14 is fixed to one end of the pull strap 15, and the other end of the pull strap 15 is fixed to the inside of the outer ring 16. The diameter of the outer ring 16 is larger than that of the central column 113. At the same time, the central column 113 is located at the center of the outer ring 16. The outer ring 16 can rotate at the top of the gas-liquid separation zone 13. Then, when the outer ring 16 rotates, the spiral spring 14 wrapped around the outside of the central column 113 will gradually contract with the pull of the pull strap 15. A fixing ring 17 is installed and fixed on the inner wall of the outer ring 16. An adhesive strip 18 is fixed on one side of the fixing ring 17 and the adhesive strip 18 is attached to the fixing ring 17. The other end is fixed to the connecting plate 19. The connecting plate 19 has a restraint strip 110. By fixing the restraint strip 110 to the waist, the anaerobic tank 11 can move freely within the range when inspecting the weld at the top of the anaerobic tank 11 with the center of the top as the axis. During the movement, the adhesive strip 18 extends with the movement of personnel, causing the outer ring 16 to rotate. At the same time, the spiral spring 14 on the outside of the center column 113 is pulled and synchronously contracted with the pull belt 15. The adhesive strip 18 always maintains a moderate tension. Therefore, when maintaining the weld, it is no longer necessary to hang it on the guardrail 12 by hook, thus eliminating the limitation of the maintenance range by the position of the guardrail 12. By designing multiple limiting wheels 112 along the circumferential direction on the outer side of the outer ring 16, and the bonding tape 18 is located between the limiting wheels 112 and the fixing ring 17, the bonding tape 18 is effectively constrained by the channel formed by the limiting wheels 112 and the fixing ring 17 during the extension process, thus preventing the bonding tape 18 from coming off the fixing ring 17. When the restraint strap 110 is removed from the waist, the spiral spring 14 uses its own restoring energy to reverse the outer ring 16 and tighten the fitting strap 18 to prevent tangling due to external environmental factors when not in use. Example

[0023] like Figures 1-2 As shown, the anti-fall mechanism 2 includes a retaining ring 21, a net ring 22 is provided on the outer side of the retaining ring 21, the outer side of the retaining ring 21 is fixedly connected to the inner side of the net ring 22, and an anaerobic tank 11 is provided at the bottom end of the retaining ring 21, the bottom end of the retaining ring 21 is fixedly connected to the top end of the anaerobic tank 11.

[0024] In this embodiment, a retaining ring 21 is designed at the top edge of the anaerobic tank 11. The retaining ring 21 can prevent tools from falling from the top of the tank due to operator error or temporary instability during maintenance work, providing additional safety protection for high-altitude operations and reducing the risk of safety accidents. At the same time, a mesh ring 22 is designed on the outside of the retaining ring 21. The holes of the mesh ring 22 are aligned with the holes of the retaining ring 21. The two work together to form an efficient drainage system. Especially in heavy rain and other heavy precipitation weather, it can quickly drain the water accumulated on the top of the tank and prevent water from stagnating on the top of the anaerobic tank 11 and causing corrosion to the metal structure of the tank top.

[0025] Working principle: like Figures 1-5As shown, a fixing ring 17 is installed and fixed on the inner wall of the outer ring 16. An adhesive strip 18 is fixed on one side of the fixing ring 17 and adheres to the fixing ring 17. The other end is fixed to the connecting plate 19. There is a restraint strip 110 on the connecting plate 19. By fixing the restraint strip 110 to the waist, the anaerobic tank 11 can move freely within the range when inspecting the weld at the top of the anaerobic tank 11 with the center of the top as the axis. During the movement, the adhesive strip 18 extends with the movement of personnel, causing the outer ring 16 to rotate. At the same time, the spiral spring 14 on the outside of the center column 113 is pulled and synchronously contracted with the pull strap 15, thus getting rid of the restriction of the maintenance range by the position of the guardrail 12. When the restraint strip 110 is released from the waist, the spiral spring 14 uses its own restoring energy to reverse the outer ring 16 and tighten the adhesive strip 18 to prevent entanglement due to external environmental influences when not in use. By fixing a retaining ring 21 at the top edge of the anaerobic tank 11, and fixing a mesh ring 22 on the outside of the retaining ring 21, the mesh ring 22 and the retaining ring 21 have the same holes. The retaining ring 21 can prevent tools from falling from the top of the tank due to operator error or temporary instability, while the mesh ring 22 can prevent water from stagnating at the top of the anaerobic tank 11 and causing corrosion to the metal structure of the tank top.
