Description

Technical Field

[0001] This utility model relates to the field of domestic sewage treatment technology, specifically to a dewatering device for domestic sewage treatment. Background Technology

[0002] The screw press sludge dewatering machine used for domestic sewage treatment is a highly efficient solid-liquid separation device. Through the rotation of the screw shaft and the filtration effect of the stacked disc structure, it concentrates, dewaters, and self-cleans the sludge, effectively removing moisture from the sludge and significantly reducing its water content. This reduces the sludge volume, facilitating subsequent transportation and disposal, and ultimately saving treatment costs, reducing land use, and minimizing environmental pollution.

[0003] For example, Chinese Patent Application No. 201810199945.9 discloses a screw press sludge dewatering machine, including an inclined screw press body. The screw press body includes a screw propeller and a filter cartridge, with the screw propeller located inside the filter cartridge. The pitch of the screw propeller's blades decreases along the propulsion direction. The filter cartridge is composed of stacked fixed rings and moving rings. This invention has the following advantages: a cylindrical filter structure formed by stacked fixed and moving rings with a screw shaft passing through them. While conveying sludge, the screw shaft drives the moving rings, automatically cleaning the filter gaps and preventing ring blockage, thus ensuring continuous and stable operation of the dewatering machine; continuous operation is possible, significantly reducing initial design and construction costs.

[0004] In the conventional use of dewatering machines for domestic sewage treatment, the discharge plate is often limited to a fixed angle, making it difficult to adapt to receiving devices of different heights or sizes, which can easily lead to material leakage. In addition, although the cover plate installed on the surface of the dewatering machine is used to protect the internal structure, it requires multiple screws to fix, making the installation and disassembly process cumbersome, thereby increasing the difficulty and time required for maintenance.

[0005] Therefore, it is necessary to redesign and modify the dewatering equipment used for domestic sewage treatment to effectively prevent material spillage or complex maintenance. Utility Model Content

[0012] As a preferred embodiment of this utility model, a reinforcing block is fixedly connected to the outer side of the support plate, and the bottom of the reinforcing block is fixedly connected to the top of the fixing plate.

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.

[0022] like Figures 1 to 4As shown, the present invention provides a dewatering device for treating domestic sewage, including a dewatering machine 1 and an angle adjustment mechanism. The angle adjustment mechanism includes a fixed plate 2 fixedly connected to the surface of the dewatering machine 1. Two support plates 3 are fixedly connected to the top of the fixed plate 2. Short rods 4 are movably connected to the inner walls of the support plates 3. Connecting rods 5 are fixedly connected to the inner sides of the short rods 4. A sliding block 6 is hinged to the top of the connecting rod 5. A limiting rod 7 is fixedly connected to the inner wall of the sliding block 6. A discharge plate 8 is fixedly connected to the left side of the limiting rod 7. A connecting block 9 is fixedly connected to the top right side of the discharge plate 8. A long rod 10 is fixedly connected to the inner wall of the connecting block 9. The front and rear ends of the long rod 10 are fixedly connected to the inner wall of the dewatering machine 1. The bottom of the connecting block 9 is fixedly connected to the top of the limiting rod 7. Protective mechanisms are provided on both the front and rear sides of the dewatering machine 1.

[0023] refer to Figure 4 The protective mechanism includes cover plates 11 installed on the front and rear sides of the dehydrator 1. Connecting plates 12 are fixedly connected to the left and right sides of the bottom of the cover plates 11. A rotating rod 13 is fixedly connected to the inner side of the connecting plate 12. Fixing blocks 14 are movably connected to the left and right sides of the surface of the rotating rod 13 through bearings. The inner side of the fixing blocks 14 is fixedly connected to the surface of the dehydrator 1. A drive mechanism is installed at the bottom of the dehydrator 1.

[0024] As a technical optimization of this utility model, by setting up a protective mechanism, through the combination of cover plate 11, connecting plate 12, rotating rod 13 and fixing block 14, the interior of the dehydrator 1 is effectively protected from external interference or damage, thereby improving the safety and service life of the equipment.

[0025] refer to Figure 3 The drive mechanism includes a dual-axis motor 15 fixedly connected to the top of the fixed plate 2. A bevel gear 16 is fixedly connected to the left output end of the dual-axis motor 15. A bevel gear 17 meshes with the surface of the bevel gear 16. The back of the bevel gear 17 is fixedly connected to the surface of the short rod 4. A transmission rod 18 is fixedly connected to the right output end of the dual-axis motor 15. A stabilizing plate 19 is movably connected to the right end of the transmission rod 18 through a bearing. The bottom of the stabilizing plate 19 is fixedly connected to the top of the fixed plate 2. A clutch mechanism is provided on the right side of the dual-axis motor 15.

[0026] As a technical optimization of this utility model, the synchronous driving of the angle adjustment mechanism and the protective mechanism is achieved by setting a drive mechanism, which not only simplifies the equipment structure but also improves work efficiency. At the same time, the design of the bevel gear and the transmission rod 18 makes the power transmission smoother and more reliable.

[0027] refer to Figure 3The clutch mechanism includes a transmission gear 20 fixedly connected to the surfaces of the transmission rod 18 and the rotating rod 13. A transmission wheel 21 is provided on the right side of each transmission gear 20. A transmission belt 22 is sleeved on the surface of the transmission wheel 21. After the transmission wheel 21 slides to the left, it can mesh with the transmission gear 20. A synchronizing plate 23 is movably connected to the right side of each transmission wheel 21 through a bearing. The synchronizing plate 23 can synchronize the left and right sliding of the two transmission wheels 21. A push plate 24 is fixedly connected to the right side of the synchronizing plate 23. The push plate 24 can be easily manually pushed to move the synchronizing plate 23.

[0028] As a technical optimization of this utility model, by setting a clutch mechanism, the user can choose whether to engage the transmission gear 20 with the transmission wheel 21 as needed, thereby achieving flexible control over the opening or closing of the cover plate 11. This not only improves the flexibility of the equipment, but also reduces energy consumption and noise.

[0029] refer to Figure 3 A handle 25 is fixedly connected to the top of the front of the push plate 24. The surface of the handle 25 is elastic and non-slip.

[0030] As a technical optimization of this utility model, the addition of a handle 25 provides users with a more convenient and comfortable operating experience. The elasticity and anti-slip properties of the handle 25 ensure that users will not slip or get injured when pushing the push plate 24.

[0031] refer to Figure 4 All the outer sides of the support plate 3 are fixedly connected with reinforcing blocks 26, and the bottom of the reinforcing blocks 26 is fixedly connected to the top of the fixed plate 2.

[0032] As a technical optimization of this utility model, the reinforcement block 26 further enhances the stability and load-bearing capacity of the support plate 3, thereby improving the overall stability and durability of the equipment. This helps ensure that the equipment maintains excellent performance and effectiveness during long-term use.

[0033] The working principle and usage process of this utility model: This equipment is a dewatering machine system 1 that integrates an angle adjustment mechanism and a protective mechanism. First, the dewatering machine 1 is responsible for processing sludge or materials, dewatering them through internal mechanical action. The angle adjustment mechanism, through components such as the support plate 3 on the fixed plate 2, short rod 4, and connecting rod 5, allows the discharge plate 8 to be adjusted in angle as needed. The sliding block 6 and the limiting rod 7 ensure the stability of the discharge plate 8 when adjusting the angle. At the same time, the connecting block 9 and the long rod 10 further enhance the stability of the structure while ensuring that the discharge plate 8 can be flipped around the long rod 10 as the axis point via the connecting block 9. The protective mechanism consists of cover plates 11 set at the front and rear of the dewatering machine 1. These cover plates 11 are connected to the dewatering machine 1 through the connecting plate 12, rotating rod 13, and fixed block 14, and can be opened or closed when needed to protect the interior of the dewatering machine 1 from external interference or damage. The drive mechanism is powered by a dual-shaft motor 15. One output of the motor drives a short rod 4 to rotate via bevel gear 16 and bevel gear 17, thereby adjusting the angle of the discharge plate 8 (the angle of the discharge plate 8 is changed by the sliding block 6 on the surface of the limit rod 7). The other output drives a rotating rod 13 to rotate via a transmission rod 18 and a transmission belt 22, which in turn drives the cover plate 11 to open or close. The clutch mechanism allows the user to select whether to engage the transmission gear 20 with the transmission wheel 21 as needed, thereby controlling the opening or closing of the cover plate 11. This avoids the inconvenience and complexity of disassembly caused by the inability to adjust the angle of the discharge plate 8 of the dewatering machine 1 and the need to manually remove the screws of the cover plate 11, making it easy to use.

[0034] In summary, when this utility model is used, under the action of the angle adjustment mechanism, the protective mechanism, the drive mechanism and the clutch mechanism, the discharge angle of the discharge plate 8 can be quickly adjusted, and the cover plate 11 can be opened and closed electrically. This avoids the inconvenience of discharge and the complexity of disassembly caused by the inability to adjust the angle of the discharge plate 8 of the dewatering machine 1 and the need to manually remove the screws of the cover plate 11. This gives it the advantage of being easy to use and solves the problems of inconvenient discharge and complex disassembly.
