Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a scum baffle for a sedimentation tank. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. A sedimentation tank is a structure that uses sedimentation to remove suspended solids from water. It is a water purification device that uses the natural sedimentation or coagulation sedimentation of water to remove suspended solids. Baffles are installed in the discharge channel of the sedimentation tank to intercept any scum that is not removed during the purification process.

[0003] However, in practical use, existing sedimentation tank scum baffles still have the following drawbacks:

[0004] Most existing scum baffles have a fixed height, which cannot adapt to changes in the water level of the sedimentation tank; even those that are adjustable can only be adjusted manually, making it difficult to flexibly and accurately match the actual water level and scum accumulation under different working conditions.

[0005] Outdated cleaning methods: Highly viscous scum easily adheres to the baffle, affecting its normal operation. Existing scum baffles are mostly cleaned manually on a regular basis, which is inefficient and increases labor costs. In addition, workers working around the sedimentation tank may face safety risks such as slipping and drowning.

[0006] In response to this technical problem, this application proposes a scum baffle for a sedimentation tank. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a scum baffle for sedimentation tanks. This device achieves automatic height adjustment by converting rotational force into lifting motion through a lifting component. The height of the baffle can be automatically adjusted according to the water level and scum accumulation, making it easy to operate and highly adaptable. Secondly, it can accurately convert the rotational force of the connecting rod into the lateral movement of the scraper, efficiently cleaning scum, reducing residue, minimizing the impact of sedimentation, and avoiding secondary pollution.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A scum baffle for a sedimentation tank includes a fixed base: a fixed column is fixedly connected to the top of the fixed base; a sliding groove is formed on the left side of the fixed column; a limiting rod is fixedly connected to the top front side of the fixed column; a scum baffle is slidably connected to the inner side of the limiting rod; a telescopic rod is fixedly connected to the top front side of the scum baffle; a connecting rod is rotatably connected to the left end of the telescopic rod; a shaft is rotatably connected to the middle inner side of the connecting rod; the shaft is fixedly connected to the front side of the scum baffle; the bottom end of the connecting rod is connected to a scraper via a movable component; the scraper is connected to the scum baffle via the limiting component; a motor is fixedly connected to the top right end of the fixed base; a support arm is fixedly connected to the drive end of the motor; the right end of the support arm is slidably connected inside the sliding groove; and the right end of the support arm is connected to the scum baffle via a lifting component.

[0010] Furthermore, the fixing seat is connected to the sedimentation tank by fixing bolts.

[0011] Furthermore, the inner wall of the sedimentation tank is connected to one outer side of the limiting rod.

[0012] Furthermore, the movable component includes a second sliding groove and a third limiting rod. The second sliding groove is formed on the front and rear sides of the inner wall of the scraper, and the third limiting rod is fixedly connected to the bottom front side of the connecting rod.

[0013] Furthermore, the limiting rod three is slidably connected to the inner wall of the sliding groove two.

[0014] Furthermore, the limiting component includes a limiting block and a second limiting groove. The limiting block is fixedly connected to the inner side of the scraper, and the second limiting groove is opened on the front side of the slag baffle.

[0015] Furthermore, the lifting assembly includes a guide groove, a limiting groove one, and a limiting rod two. The guide groove is opened on the front side of the inner wall of the sliding groove one, the limiting groove one is opened on the top of the outer side of the support arm, and the limiting rod two is fixedly connected to the top of the rear side of the slag baffle plate.

[0016] Furthermore, the inner walls of both the guide groove and the limiting groove are slidably connected to the limiting rod.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, automatic height adjustment is achieved. The support arm is driven by a motor and slides stably up and down in the chute. The rotational force is accurately converted into the lifting force of the slag baffle plate by the lifting component. The height of the slag baffle plate can be automatically, flexibly and accurately adjusted according to different water levels and scum accumulation, without the need for manual intervention, which greatly improves the convenience and adaptability of operation.

[0019] 2. In this utility model, the rotational force of the connecting rod is accurately converted into the lateral movement of the scraper, which can accurately, stably and efficiently clean up scum and minimize the residue of scum in the sedimentation tank. This not only reduces the impact of scum on the sedimentation effect, but also avoids the risk of residual scum decomposing and deteriorating due to long-term accumulation, producing odor or causing secondary pollution to the water body, which is conducive to maintaining the cleanliness of the sedimentation tank and the surrounding environment.

[0028] 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.

[0029] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of a scum baffle for a sedimentation tank, comprising a fixed base 1: a fixed column 2 is fixedly connected to the top of the fixed base 1, and a sliding groove 7 is provided on the left side of the fixed column 2, providing a precise track for the sliding of the support arm 6, ensuring the stability and accuracy of the support arm 6 during movement; a limiting rod 3 is fixedly connected to the top front side of the fixed column 2, and a scum baffle 4 is slidably connected to the inner side of the limiting rod 3, which limits and guides the scum baffle 4, enabling it to slide stably along a predetermined trajectory; a telescopic rod 9 is fixedly connected to the top front side of the scum baffle 4, and a connecting rod 10 is rotatably connected to the left end of the telescopic rod 9; a shaft 11 is rotatably connected to the middle inner side of the connecting rod 10, and the shaft 11 is fixedly connected to the front side of the scum baffle 4. This connection method allows the connecting rod 10 to flexibly rotate around the shaft 11. The rotating mechanism works in conjunction with the telescopic rod 9. The bottom end of the connecting rod 10 is connected to the scraper 13 via the movable component 12. The scraper 13 is connected to the baffle plate 4 via the limiting component 14. The limiting component 14 further restricts the lateral movement range of the scraper 13, ensuring that it remains within the effective working area when cleaning scum, thus improving cleaning efficiency and preventing the scraper 13 from deviating from its normal working trajectory. A motor 5 is fixedly connected to the top right end of the fixed base 1. A support arm 6 is fixedly connected to the drive end of the motor 5. The right end of the support arm 6 is slidably connected inside the chute 7. The right end of the support arm 6 is connected to the baffle plate 4 via the lifting component 8. Driven by the motor 5, the support arm 6 can slide stably up and down along the chute 7, thereby driving the baffle plate 4 to achieve lifting and lowering functions through the lifting component 8, adapting to different water levels and scum accumulation conditions.

[0030] Reference Figure 2 , Figure 4 and Figure 6The fixing seat 1 is connected to the settling tank 15 via the fixing bolt 16. This connection method allows the fixing seat 1 to be stably installed on the settling tank 15, providing a solid and reliable foundation support for the entire scum baffle structure. The inner wall of the settling tank 15 is connected to the outer side of the limiting rod 3. This connection with the inner wall of the settling tank 15 further enhances the fit and stability of the entire structure with the settling tank 15. The movable component 12 includes a second sliding groove 1201 and a third limiting rod 1202. The second sliding groove 1201 is opened on the front and rear sides of the inner wall of the scraper 13, and the third limiting rod 1202 is fixedly connected to the connecting rod. At the front bottom end of the 10, the limiting rod 1202 is slidably connected to the inner wall of the chute 1201. The limiting component 14 includes a limiting block 1401 and a limiting groove 1402. The limiting block 1401 is fixedly connected to the inner side of the scraper 13, and the limiting groove 1402 is opened on the front side of the baffle plate 4. During operation, the movable component 12 and the limiting component 14 are tightly engaged. When the connecting rod 10 rotates around the shaft 11, the limiting rod 1202 of the movable component 12 slides in the chute 1201, which in turn engages with the limiting block 1401 of the limiting component 14 in the limiting groove 1402. The limiting function cleverly converts the rotational force of the connecting rod 10 into the lateral movement of the scraper 13, allowing the scraper 13 to slide precisely and stably in a specific direction under the drive of the connecting rod 10. This ensures the stability of the scraper 13 during movement, preventing wobbling or deviation, and ensuring efficient and precise cleaning of scum. The lifting assembly 8 includes a guide groove 801, a first limiting groove 802, and a second limiting rod 803. The guide groove 801 is located on the front side of the inner wall of the slide groove 7, the first limiting groove 802 is located at the top outer side of the support arm 6, and the second limiting rod 803... 3. Fixedly connected to the top rear side of the baffle plate 4, the inner walls of the guide groove 801 and the limiting groove 802 are slidably connected to the limiting rod 803. When the support arm 6 rotates, the limiting groove 802 at its outer top moves along the limiting rod 803. At the same time, the guide groove 801 guides and constrains the movement of the limiting rod 803. Through this structure, the rotational force of the motor 5 on the support arm 6 is converted into the lifting force of the baffle plate 4, so that the baffle plate 4 can stably and accurately realize the lifting function under different water levels and scum accumulation conditions, ensuring the smooth progress of the entire scum cleaning process.

[0031] Working principle: First, the fixing seat 1 is firmly installed on the sedimentation tank 15 by the fixing bolt 16. The sliding groove 7 on the fixing column 2 provides a sliding track for the support arm 6. The limiting rod 3 limits and guides the slag baffle 4. The motor 5 drives the support arm 6 to slide up and down in the sliding groove 7. The lifting component 8 converts the rotational force into the lifting force of the slag baffle 4 to adapt to different water levels and scum accumulation. The telescopic rod 9 on the slag baffle 4 cooperates with the connecting rod 10, so that the connecting rod 10 can rotate around the shaft 11. The limiting rod 1202 of the movable component 12 slides in the sliding groove 1201 of the scraper 13. Combined with the limitation of the limiting block 1401 in the limiting component 14 in the limiting groove 1402 of the slag baffle 4, the rotational force of the connecting rod 10 is converted into the lateral movement of the scraper 13, realizing efficient and precise cleaning of scum.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
