Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a packing tray for wastewater treatment. Background Technology

[0002] In the field of wastewater treatment, efficient treatment equipment is crucial for improving wastewater treatment quality and reducing environmental pollution. Among them, packing trays, as key components of wastewater treatment systems, directly affect the efficiency and effectiveness of wastewater treatment. However, existing wastewater treatment packing trays have revealed many problems that urgently need to be solved in practical applications.

[0003] First, existing packing trays cannot adaptively adjust the height of the packing material according to changes in the wastewater level. During wastewater treatment, the wastewater level fluctuates due to various factors, such as uneven wastewater discharge and changes in water volume at different stages of the treatment process. The packing material on traditional packing trays is usually fixed in a specific position and cannot be adjusted accordingly based on changes in the water level. When the water level is low, some packing material cannot fully contact the wastewater, resulting in its purification function not being fully utilized and wasting packing material resources. When the water level is high, the packing material may be over-submerged, which also affects its contact effect with the wastewater, resulting in a significant reduction in purification efficiency. This inability to adaptively adjust the height of the packing material according to the water level severely restricts the purification efficiency of wastewater treatment and makes it difficult to meet the complex and ever-changing operating conditions required in actual wastewater treatment processes.

[0004] Secondly, existing packing trays are insufficient in their capacity to treat solid waste in sewage. Sewage often contains a large amount of solid waste, such as silt, suspended solids, and garbage fragments. Traditional packing trays lack effective solid-liquid separation and diversion storage mechanisms. When these solid wastes flow into the packing tray, they tend to accumulate at the inlet, hindering the smooth flow of sewage. As solid wastes accumulate, they may block subsequent treatment channels, affecting the normal operation of the entire sewage treatment process. Moreover, unseparated solid wastes entering the treatment stage along with sewage will increase the burden on the treatment equipment, reduce treatment efficiency, and may even cause wear and damage to the treatment equipment, shortening its service life. Utility Model Content

[0005] The purpose of this utility model is to provide a packing tray for sewage treatment, so as to solve the problems mentioned in the background art that the existing packing trays are difficult to adaptively adjust the packing height according to changes in sewage water level and have insufficient capacity to treat solid waste in sewage.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a filler tray for sewage treatment, including a support frame, a central column fixedly disposed in the center of the upper surface of the support frame, and a rotating connecting flange fixedly installed at the upper end of the central column; the surface of the support frame is provided with an adjustment and purification mechanism, which realizes the switching of the filler position by detecting the sewage injection state, thereby enabling the filler to adaptively adjust the suspension height according to the water level.

[0007] The adjustment and purification mechanism includes: an impeller, which is rotatably installed inside the lower end of the central column, and a connecting rod is fixedly connected to the lower end of the impeller shaft. A rotating disk is fixedly connected to the upper end of the connecting rod. A clearance groove is provided on the outer surface of the support frame. A lifting ring is fixedly provided on the inner surface of the clearance groove. A guide ring is fixedly provided on the upper surface of the rotating disk. One end of a connecting chain is fixedly connected to the outer surface of the lifting ring, and the other end of the connecting chain passes through the guide ring. A suspended packing is fixedly connected to the upper end of the connecting chain.

[0008] The upper end of the central column is equipped with a waste diversion mechanism, which ensures the smooth inflow of sewage and solid-liquid separation by diverting and storing solid waste;

[0009] The waste diversion mechanism includes: a waste storage plate, which is fixedly installed on the upper outer surface of the central column, a filter screen is fixedly installed inside the upper end of the central column, and a sliding closing plate is installed on the lower outer surface of the waste storage plate.

[0010] Preferably, the rotary disk is rotatably connected to the central column, and the surface of the rotary disk has a slot that matches the shape of the clearance groove.

[0011] By adopting the above technical solution, the rotating disc can rotate flexibly around the central column, thereby achieving precise adjustment of the position of the suspended packing.

[0012] Preferably, the lifting ring and the guide ring are arranged in a one-to-one correspondence, and the guide ring and the lifting ring are distributed at equal angles.

[0013] By adopting the above technical solution, it is possible to ensure that the suspended packing is evenly distributed around the support frame, so that the purification effect of the packing on the sewage is more balanced at different positions, thereby improving the overall sewage treatment effect.

[0014] Preferably, the waste storage plate is a frustum-shaped design with a smaller top and a larger bottom, and the waste storage plate is hollow, with an open bottom.

[0015] The above technical solution uses a frustum-shaped design that is smaller at the top and larger at the bottom to guide the intercepted solid waste to slide down the surface of the waste storage plate into the internal storage. The hollow design increases the waste storage space, and the open design at the bottom facilitates the subsequent cleaning of solid waste and centralized processing, effectively realizing the function of diverting and storing solid waste.

[0016] Preferably, the filter screen is tapered, and the lower end of the filter screen is fixedly connected to the upper end of the waste storage plate.

[0017] By adopting the above technical solution, the conical filter screen can increase the contact area with sewage and improve the interception efficiency of solid waste. At the same time, its inclined surface makes it easy for solid waste to slide smoothly into the waste storage plate under the action of gravity and be tightly connected with the waste storage plate, ensuring the continuity and efficiency of the solid-liquid separation process.

[0018] Preferably, the lower inner surface of the sealing plate is in contact with the lower opening of the waste storage plate, and a spring is connected between the sealing plate and the outer surface of the waste storage plate.

[0019] Using the above technical solution, during normal wastewater treatment, the spring force keeps the sealing plate tightly fitted to the lower opening of the waste storage plate, preventing solid waste leakage and ensuring solid-liquid separation. When it is necessary to clean the solid waste, simply overcome the spring force to pull open the sealing plate; the operation is simple, enabling convenient cleaning and maintenance of the waste inside the waste storage plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the wastewater treatment packing tray:

[0021] 1. The adjustment and purification mechanism works in concert with components such as impeller, connecting rod, rotating disk, guide ring, lifting ring and connecting chain. It can switch the position of the packing material according to the sewage injection status. When the sewage level changes, the water flow impacts the impeller to rotate, which drives the connecting rod and rotating disk to rotate. This causes the connecting chain to pull the suspended packing material, realizing adaptive adjustment of the suspension height. This ensures that the packing material and sewage always maintain good contact, improves the sewage treatment and purification efficiency, and avoids the problem of poor treatment effect caused by water level changes.

[0022] 2. Furthermore, the waste storage plate is a hollow, frustum-shaped structure with a smaller top and a larger bottom, and an opening at the bottom. Combined with a conical filter screen, it can effectively separate solids and liquids in wastewater. When wastewater flows in, solid waste is intercepted by the filter screen and slides down the surface of the waste storage plate into the plate for storage, thus achieving solid-liquid separation. This ensures that wastewater flows smoothly into subsequent treatment stages and reduces the interference of solid waste on the treatment process.

[0023] Furthermore, the sealing plate installed on the lower outer side of the waste storage plate fits into the lower opening of the waste storage plate under the action of a spring. When it is necessary to clean up solid waste, simply overcome the spring force and pull the sealing plate upward to easily discharge the solid waste inside the waste storage plate. The maintenance process is simple and convenient. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1-6 This utility model provides a technical solution: a packing tray for sewage treatment.

[0033] Example 1

[0034] This embodiment discloses: a support frame 1, a central column 2 fixedly installed in the middle of the upper surface of the support frame 1, and a rotating connecting flange 3 fixedly installed at the upper end of the central column 2. The surface of the support frame 1 is provided with an adjustment and purification mechanism, which realizes the switching of the packing position by detecting the sewage injection state, so that the packing can adaptively adjust the suspension height according to the water level.

[0035] The adjustment and purification mechanism includes: an impeller 4, which is rotatably installed inside the lower end of the central column 2, and a connecting rod 5 is fixedly connected to the lower end of the shaft of the impeller 4. A rotating disk 6 is fixedly connected to the upper end of the connecting rod 5. A clearance groove 7 is opened on the outer surface of the support frame 1. A lifting ring 8 is fixedly installed on the inner surface of the clearance groove 7. A guide ring 9 is fixedly installed on the upper surface of the rotating disk 6. One end of a connecting chain 10 is fixedly connected to the outer surface of the lifting ring 8, and the other end of the connecting chain 10 passes through the guide ring 9. A suspended packing 11 is fixedly connected to the upper end of the connecting chain 10.

[0036] The rotary disk 6 is rotatably connected to the central column 2, and the surface of the rotary disk 6 is provided with a slot that matches the shape of the relief groove 7.

[0037] The lifting ring 8 and the guide ring 9 are set in a one-to-one correspondence, and the guide ring 9 and the lifting ring 8 are distributed at equal angles;

[0038] When sewage is injected from the pipe connected to the connecting flange 3, the water flow will impact the impeller 4 installed inside the lower end of the central column 2, causing it to rotate. The shaft of the impeller 4 is fixedly connected to the connecting rod 5, so the rotation of the impeller 4 will drive the connecting rod 5 to rotate, which in turn will cause the disc 6 connected to the upper end of the connecting rod 5 to rotate together. Since the rotating disk 6 is rotatably connected to the central column 2, and its surface has a slot that matches the shape of the relief groove 7, smooth rotation is ensured. A lifting ring 8 is fixedly installed inside the relief groove 7 on the outer surface of the support frame 1. The lifting ring 8 is connected to the suspended packing 11 through the connecting chain 10. As the rotating disk 6 rotates, the position of the guide ring 9 changes, pulling the connecting chain 10. This allows the suspended packing 11 to switch positions according to the sewage injection state under the action of the connecting chain 10. When the sewage is first injected, the water level is low. At this time, the suspended packing 11 is driven to move downward to ensure that the suspended packing 11 can be submerged in the water and ensure full contact with the lower water body. As the sewage injection is completed, the suspended packing 11, under the action of buoyancy, pulls the guide ring 9 in the opposite direction through the connecting chain 10, causing the rotating disk 6 to rotate in the opposite direction. This allows the suspended packing 11 to float upward. At this time, the suspended packing 11 finally stops at a suitable position in the sewage treatment tank to ensure the purification effect when the water level is high.

[0039] Example 2

[0040] This embodiment discloses, based on embodiment 1, that: a waste diversion mechanism is provided at the upper end of the central column 2, which ensures the smooth inflow of sewage and solid-liquid separation by diverting and storing solid waste;

[0041] The waste diversion mechanism includes: a waste storage plate 12, which is fixedly installed on the upper outer surface of the central column 2, a filter screen 13 is fixedly installed inside the upper end of the central column 2, and a sliding closing plate 14 is installed on the lower outer surface of the waste storage plate 12.

[0042] The waste storage plate 12 is a frustum-shaped design with a smaller top and a larger bottom, and the waste storage plate 12 is hollow, with an open bottom.

[0043] The filter screen 13 has a conical design, and the lower end of the filter screen 13 is fixedly connected to the upper end of the waste storage plate 12.

[0044] The lower inner surface of the sealing plate 14 is in contact with the lower opening of the waste storage plate 12, and a spring is connected between the sealing plate 14 and the outer surface of the waste storage plate 12.

[0045] When wastewater flows into the central column 2, it first passes through the conical filter screen 13 located inside the upper end of the central column 2. Because the filter screen 13 is conical and its lower end is fixedly connected to the upper end of the waste storage plate 12, solid waste in the wastewater is intercepted by the filter screen 13 and slides down the conical surface of the filter screen 13 into the waste storage plate 12 for storage. A sealing plate 14 is installed on the lower outer surface of the waste storage plate 12. Under the action of a spring, the lower inner surface of the sealing plate 14 is tightly fitted with the lower opening of the waste storage plate 12 to prevent solid waste stored in the waste storage plate 12 from falling out. When it is necessary to clean the solid waste, simply overcome the elastic force of the spring and slide the sealing plate 14 upward to open it, and the solid waste can be discharged from the lower opening of the waste storage plate 12. Through such a waste diversion mechanism, the solid waste in the wastewater is diverted and stored, ensuring that the wastewater can flow smoothly into the subsequent treatment stage, effectively realizing solid-liquid separation, and reducing the interference of solid waste on the wastewater treatment process.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
