Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment technology, specifically relating to a floating debris removal device for sewage treatment. Background Technology

[0002] In the field of industrial wastewater and municipal sewage treatment, efficient removal of floating debris from the water surface is a key step to ensure the normal operation of subsequent purification processes. This is especially important for sewage containing complex components such as oil, plastic particles, and algae. Traditional sewage treatment systems typically use filter plates to screen floating debris in the sewage. While this method can intercept floating debris to some extent, its structural design is relatively simple, and its filtration precision is limited. It cannot adapt to complex water environments with varying pollution levels and different pollutant compositions. With the diversification of industrial production, the composition of discharged sewage is becoming increasingly complex, and the filtration effect of a single type of filter plate is clearly insufficient. Operators need to frequently replace filter plates with different pore sizes and materials to cope with changing water quality conditions.

[0003] In scenarios involving significant seasonal water quality changes or mixed treatment of multiple types of wastewater, equipment maintenance personnel need to quickly adjust the treatment process based on real-time monitoring data. This places higher demands on the adaptability of the floating debris removal device. The filter plate replacement process in existing technologies usually requires shutdown operations, and the disassembly process is cumbersome, involving the disassembly and assembly of multiple fasteners, which is time-consuming. In actual operation, this design, which is not convenient for quick disassembly and installation, significantly reduces the operating efficiency of the treatment system, increases downtime and maintenance costs, and also limits the equipment's emergency response capability to sudden changes in water quality, failing to meet the urgent needs of modern wastewater treatment plants for efficient and flexible operation.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a floating debris removal device for sewage treatment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A floating debris removal device for sewage treatment includes a support frame with a screening mechanism. The screening mechanism includes a filter plate and a lifting mechanism. The filter plate is installed on the outside of the support frame. A quick-installation mechanism is provided on the support frame, including a rod and a fixed sleeve. The fixed sleeve is inserted into the top of the rod. The outer wall of the rod has a slot. The outer wall of the fixed sleeve has a movable groove. Multiple sets of movable grooves are provided, and push blocks are slidably installed inside each groove. Slider blocks are fixedly installed on the bottom surface of each set of push blocks. Slider blocks slide on the outer wall of the fixed sleeve, and a locking block is fixedly installed at their bottom ends. A limiting mechanism is provided on the outside of the fixed sleeve. The limiting mechanism includes a limiting sleeve and a rotating sleeve. The limiting sleeve slides on the outer wall of the fixed sleeve and has a limiting groove on its outer side. The rotating sleeve rotates on the outer wall of the fixed sleeve and has a limiting rod fixedly installed on its outer side. Multiple sets of limiting rods are provided, and each has a limiting block fixedly installed on its inner wall. Multiple sets of limiting blocks are provided and slide within the limiting grooves.

[0007] Furthermore, the lifting mechanism includes a rotating rod and a lifting shovel. Multiple sets of rotating rods are respectively rotatable on the outside of the support frame. Each end of each set of rotating rods is fixed with a hinge wheel, and each set of hinge wheels is connected to a hinge chain on its outer side. Multiple sets of lifting shovels are respectively fixed between the multiple sets of hinge chains. A motor is fixed to the outer wall of the support frame, and the output end of the motor is fixedly connected to the rotating rod. This design forms a continuous motion chain system, enabling automatic retrieval and transport of floating objects on the water surface. The multi-point distribution of the lifting shovels increases the operating coverage area, and the hinge connection method allows the lifting shovels to adapt to changes in water level and maintain the optimal working angle.

[0008] Furthermore, multiple sets of push springs are connected between the inner walls of the push blocks and the movable grooves. The push springs provide restoring force to the push blocks, enabling the locking system to have a self-locking function. This ensures that the push blocks will not move on their own in a vibration environment, and at the same time, it facilitates the push blocks to quickly return to their original position when unlocking, thereby improving the ease of operation and safety of the device.

[0009] Furthermore, an unlocking slot is provided on the outer side of the limiting slot. Multiple sets of unlocking slots are provided. The design of the unlocking slots allows the limiting block to release the limiting sleeve at a specific position, realizing a one-step unlocking operation, simplifying the operation process, reducing unlocking time, and improving maintenance efficiency.

[0010] Furthermore, the outer walls of the multiple sets of push blocks are all set as inclined surfaces, and the inner walls of the limiting sleeves are set as arc shapes. The inclined surface and arc shape design reduces the contact friction between the push blocks and the limiting sleeves, allowing the limiting sleeves to slide smoothly, reducing the operating force, and improving the wear resistance and service life of the components.

[0011] Furthermore, both the support frame and the filter plate are provided with insertion holes, and the insertion rod is inserted into the insertion hole. The matching design of the insertion hole and the insertion rod ensures the precise positioning of the filter plate installation position, prevents the filter plate from shifting during operation, simplifies the alignment process, and improves installation efficiency and accuracy.

[0012] Furthermore, the insertion rod has a sliding hole, and a top block is movably installed in the sliding hole. A compression spring is connected between the top block and the sliding hole. The combination design of the compression spring and the top block enables the insertion rod to automatically pop out. When the locking is released, the insertion rod can be actively pushed out without the need for additional tools to assist in disassembly, which greatly simplifies the disassembly process and improves maintenance efficiency.

[0013] Furthermore, a collection box is installed at the top of the support frame. The collection box is designed to facilitate the centralized storage of the screened floating objects, avoiding secondary pollution, and also facilitating subsequent processing and cleaning, thereby improving the working efficiency and environmental performance of the entire removal system.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) The screening mechanism of this utility model adopts an innovative combination design of filter plate and lifting shovel. Multiple sets of rotating rods drive the hinge wheel to rotate. The hinge wheel is connected to the lifting shovel through the hinge to form a continuous motion chain, realizing the automatic collection and transportation of floating objects on the water surface. The motor drives the entire system to operate stably to ensure work efficiency. The filter plate design can select the appropriate aperture according to different sewage types. The multi-point distribution of the lifting shovel increases the coverage area of ​​a single operation. The hinge connection method enables the lifting shovel to adapt to water level changes and maintain the best working angle. The collection box is set up to facilitate centralized storage of the screened floating objects for subsequent processing. The overall structure forms a set of efficient and continuous floating object collection, screening and collection system, which significantly improves sewage treatment efficiency and treatment quality.

[0015] (2) The quick-installation mechanism of this utility model adopts a quick connection structure with the insertion rod and the fixed sleeve. The interlocking of the slot and the block achieves a firm connection. Multiple push blocks slide along the movable slot to control the extension and retraction of the block. The slider, as a force transmission component, ensures the accuracy of the block movement. The push spring provides the restoring force for the push block, enabling the system to have a self-locking function. The design of the insertion rod into the insertion hole makes the filter plate accurately positioned and not easily offset. The combination of the compression spring and the top block gives the insertion rod an automatic pop-out function, which is convenient for disassembly. The inclined push block reduces the operating resistance and improves the assembly smoothness. The overall structure can be quickly installed and disassembled without tools, which greatly reduces the equipment maintenance time and labor intensity, and improves the maintenance efficiency and adaptability of the equipment.

[0016] (3) The limiting mechanism of this utility model achieves reliable locking of the quick-installation mechanism through the coordinated work of the limiting sleeve and the rotating sleeve. The sliding sleeve of the limiting sleeve forms an effective constraint on the push block on the outer wall of the fixed sleeve. The rotating sleeve drives the limiting rod and the limiting block to move through rotation to achieve the locking and unlocking functions. The design of the limiting groove and the unlocking groove ensures that the limiting block can only move in the predetermined track to prevent misoperation. The arc-shaped inner wall of the limiting sleeve reduces the friction between it and the push block and enhances the smoothness of operation. The setting of multiple sets of limiting blocks disperses the bearing force and improves the stability and reliability of locking. The ingenious design of the unlocking groove enables the limiting block to release the limiting sleeve at a specific position to achieve one-step unlocking. The whole system forms a safe and reliable double locking system, which effectively prevents the filter plate from loosening and falling off during use and significantly improves the safety and stability of the equipment under harsh working conditions.

[0019] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example See appendix Figure 1-5A floating debris removal device for sewage treatment includes a support frame 1, on which a screening mechanism is provided. The screening mechanism includes a filter plate 2 and a lifting mechanism. The filter plate 2 is installed on the outside of the support frame 1. A quick-installation mechanism is provided on the support frame 1, which includes an insertion rod 3 and a fixing sleeve 4. The fixing sleeve 4 is inserted into the top of the insertion rod 3. A slot 5 is formed on the outer wall of the insertion rod 3, and a movable groove 6 is formed on the outer wall of the fixing sleeve 4. Multiple sets of push blocks 7 are provided in the movable groove 6 and slide inside. The bottom surfaces of the multiple sets of push blocks 7 are fixed. A slider 8 is provided, and multiple sets of sliders 8 slide on the outer wall of the fixed sleeve 4 and a locking block 9 is fixed at the bottom. A limiting mechanism is provided on the outside of the fixed sleeve 4. The limiting mechanism includes a limiting sleeve 10 and a rotating sleeve 11. The limiting sleeve 10 slides on the outer wall of the fixed sleeve 4 and a limiting groove 12 is opened on the outside. The rotating sleeve 11 rotates on the outer wall of the fixed sleeve 4 and a limiting rod 13 is fixed on the outside. Multiple sets of limiting rods 13 are provided, and each of them has a limiting block 14 fixed on its inner wall. Multiple sets of limiting blocks 14 are provided and slide in the limiting groove 12.

[0021] The lifting mechanism includes a rotating rod 15 and a lifting shovel 16. The rotating rod 15 has multiple sets that rotate on the outside of the support frame 1. Each end of the rotating rod 15 is fixed with a hinge wheel 17, and each hinge wheel 17 is connected to a hinge 18 on its outside. The lifting shovel 16 has multiple sets that are fixed between the multiple sets of hinges 18. A motor 19 is fixedly installed on the outer wall of the support frame 1. The output end of the motor 19 is fixedly connected to the rotating rod 15. This mechanism drives the rotating rod 15 to rotate through the motor 19, which in turn drives the hinge wheels 17 to rotate. The hinge wheels 17 drive the lifting shovel 16 to form a continuous lifting action through the hinges 18, thereby realizing the automatic retrieval and transportation of floating objects on the water surface. The multi-point distribution design increases the operating coverage area and improves the removal efficiency.

[0022] Push springs 20 are connected between the inner walls of multiple sets of push blocks 7 and the movable groove 6. Multiple sets of push springs 20 are provided to provide continuous restoring force to the push blocks 7, so that the snap-fit ​​system has a self-locking function. When the external force is released, the push blocks 7 can automatically return to the locked state under the action of the push springs 20, ensuring that the snap-fit ​​system remains stable and reliable in the environment of equipment vibration.

[0023] An unlocking slot 21 is provided on the outer side of the limiting slot 12. Multiple sets of unlocking slots 21 are provided. The unlocking slot 21 and the limiting slot 12 form a dual-position guide system. When unlocking is required, the limiting block 14 slides from the limiting slot 12 into the unlocking slot 21 to release the constraint on the limiting sleeve 10, realize the quick unlocking function, and simplify the operation process.

[0024] The outer walls of multiple push blocks 7 are all set as inclined surfaces, and the inner walls of the limiting sleeve 10 are set as arcs. The structural design of the inclined surface and the arc reduces the contact friction between the push block 7 and the limiting sleeve 10, allowing the limiting sleeve 10 to slide smoothly on the inclined surface, reducing operating resistance, while increasing the contact area to disperse stress and improve the durability of the components.

[0025] Both the support frame 1 and the filter plate 2 are provided with insertion holes 22. The insertion rod 3 is inserted into the insertion hole 22. The cooperation design of the insertion hole 22 and the insertion rod 3 constitutes a preliminary positioning system, which ensures that the filter plate 2 and the support frame 1 are accurately aligned and installed, preventing positional deviation during operation. It also simplifies the disassembly and assembly process and improves maintenance efficiency.

[0026] The insertion rod 3 has a sliding hole 23, and a top block 24 is movably installed in the sliding hole 23. A compression spring 25 is connected between the top block 24 and the sliding hole 23. The compression spring 25 and the top block 24 form an elastic ejection mechanism. When the locking is released, the compression spring 25 releases energy to push the top block 24, thereby pushing the insertion rod 3 to pop out automatically. No additional tools are needed for disassembly, which greatly simplifies the disassembly operation.

[0027] A collection box 26 is installed at the top of the support frame 1. The collection box 26 serves as a temporary storage container for floating objects, receiving floating objects transported up by the lifting shovel 16. This enables centralized collection and closed storage of waste, avoids secondary pollution, facilitates subsequent regular cleaning and treatment, and completes the working loop of the entire system.

[0028] In use, the support frame 1 is placed in the sewage or the sewage is transported to the outside of the filter plate 2 via an external conveying device. The motor 19 is started, driving the rotating rod 15 to rotate. The rotating rod 15 drives multiple sets of hinged wheels 17 to rotate, which in turn drives the hinges 18 to move. The hinges 18 then drive multiple lifting shovels 16 to lift floating objects in the sewage. These floating objects are then filtered through the filter plate 2 and transported to the collection box 26. When the filter plate 2 needs to be replaced, the rotating sleeve 11 is rotated... Multiple sets of limiting rods 13 rotate, causing multiple sets of limiting blocks 14 to slide into the unlocking groove 21, releasing the limiting sleeve 10 from the limiting blocks 14, pushing the limiting sleeve 10 to release its contact with the multiple sets of push blocks 7, and pushing the push blocks 7 to slide along the movable groove 6 through multiple sets of push springs 20, and pulling the locking block 9 out of the locking groove 5 through the slider 8, thereby releasing the locking of the insertion rod 3, and pushing the top block 24 to reset through the compression spring 25, while pushing the insertion rod 3 to disengage from the fixing sleeve 4 and the insertion hole 22, thereby disassembling the filter plate 2.

[0029] When the filter plate 2 needs to be installed, align the insertion hole 22 on the filter plate 2 with the insertion hole 22 on the support frame 1, insert the insertion rod 3 into the insertion hole 22 and then insert it into the fixing sleeve 4. The top block 24 abuts against the inner wall of the fixing sleeve 4 to compress the compression spring 25, pushing the limiting sleeve 10 to abut against the outer wall of the multiple sets of push blocks 7 so that the multiple sets of push blocks 7 slide along the movable groove 6 and compress the push spring 20. At the same time, the slider 8 pushes the locking block 9 to engage in the locking groove 5, inserting the insertion rod 3. At this time, the multiple sets of limiting blocks 14 are in the unlocking groove 21. Rotate the rotating sleeve 11 to drive the limiting block 14 to slide into the limiting groove 12 through the multiple sets of limiting rods 13, thereby limiting the limiting sleeve 10 and completing the fixed installation of the filter plate 2.

[0030] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
