Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a phosphorus removal agent feeding device for wastewater treatment. Background Technology

[0002] The activated sludge process is a treatment technology used in most wastewater treatment plants. The general process of wastewater treatment using the activated sludge process is as follows: wastewater → trash rack → sedimentation tank → biological treatment tank (aeration tank) → secondary sedimentation tank → disinfection tank (ultraviolet disinfection) → discharge after meeting standards. It utilizes the biological coagulation, adsorption, and oxidation of activated sludge to decompose and remove organic pollutants in wastewater. In the operation and management of wastewater treatment processes, the mixed liquor concentration, settling ratio, sludge index, and influent and effluent water quality in the aeration tank are used as the main parameters to guide operation. By measuring the sludge settling ratio, the flocculation and sedimentation process of activated sludge can be observed at any time to understand the characteristics of activated sludge, control the amount of activated sludge, and judge the operation status of the aeration tank process.

[0003] Currently, our company's research on activated sludge performance in wastewater treatment plants is limited to sludge settling properties, sludge loading, and sludge age, lacking a comprehensive analysis of all sludge performance factors and parameters affecting sludge performance. Furthermore, there is a lack of scientific operational plans for phosphorus removal agent dosing in activated sludge systems. Therefore, to improve the treatment efficiency of activated sludge systems in wastewater treatment plants, it is essential to analyze sludge performance factors and research phosphorus removal agent dosing schemes.

[0004] Currently, polymeric AlCl3 is commonly used as a chemical phosphorus removal agent. When adding it to wastewater treatment ponds, the bagged phosphorus removal agent is typically poured into a conveyor elevator, mixed, and then directly added to the wastewater. This results in uneven distribution of the phosphorus removal agent and a tendency for clogging during addition. Therefore, there is an urgent need to design a phosphorus removal agent feeding device for wastewater treatment to solve these problems. Utility Model Content

[0035] In this embodiment, a storage tank 1 is included;

[0036] Specifically, the top of the storage bin 1 is provided with a lid 11, and a pull ring 12 is provided on the outer wall of the top of the lid 11. The lid 11 is used to seal the top of the storage bin 1. The pull ring 12 is a folding structure, which makes it easy to remove the lid 11 from the top of the storage bin 1.

[0037] Specifically, a discharge pipe 13 is provided at the bottom of the storage tank 1, and the container 3 is slidably inserted into the inside of the discharge pipe 13;

[0038] Specifically, a guide groove is provided on one side of the discharge pipe 13, and the slider 34 of the container 3 is slidably inserted into the inside of the guide groove, ensuring that the container 3 can move vertically in a straight line.

[0039] In this embodiment, a support component 2 is fixedly installed at the bottom of the storage tank 1. The support component 2 is used for at least the fixed installation and stable support of the storage tank 1.

[0040] Specifically, the support component 2 includes a fixing ring 21 installed at the bottom of the storage tank 1, and a number of support legs 22 are provided on the outer wall of the bottom of the fixing ring 21, and a base 23 is fixedly installed at the bottom end of the support legs 22.

[0041] Specifically, the support leg 22 has an arc-shaped structure, and a guide groove 24 is provided on one side of the support leg 22. A collection cup 25 is provided on one side of the support leg 22 above the base 23. When the phosphorus removal agent is sprayed by the dispersion mechanism 4, the phosphorus removal agent blocked by the support leg 22 can slide down along the guide groove 24 and be collected by the collection cup 25, thereby realizing the recovery of the phosphorus removal agent.

[0042] In this embodiment, a sliding container 3 is provided at the bottom of the storage tank 1. The container 3 is used at least to measure the amount of dephosphorizing agent added at one time.

[0043] Specifically, container 3 includes a material cylinder 31. A liner 33 is provided on the outer wall of the top side of the material cylinder 31. A top plate 32 is fixedly installed on the top of the liner 33. The liner 33 is used to achieve a fixed connection between the material cylinder 31 and the top plate 32, forming a large opening on one side of container 3. After container 3 is raised and enters the storage tank 1, it is convenient for the dephosphorizing agent inside the storage tank 1 to enter container 3. A slider 34 is provided on the outer wall of the top plate 32. The slider 34 is used to limit the up and down movement of container 3.

[0044] In this embodiment, a dispersing mechanism 4 located directly below the storage tank 1 is installed on the support component 2. The dispersing mechanism 4 is used at least to uniformly disperse the phosphorus removal agent discharged from the storage tank 1 in the sewage tank.

A motor 42 is provided at the bottom of the mounting frame 41, and a turntable 43 connected to the motor 42 is provided at the top of the mounting frame 41. Several baffles 44 are provided on the outer wall of the top of the turntable 43 in a ring at equal intervals. When the motor 42 is started, it can drive the turntable 43 to rotate at high speed, so that the baffles 44 can hit the dephosphorizing agent. Under the action of centrifugal force of the turntable 43 and the baffles 44, the dephosphorizing agent is evenly thrown outward.

[0046] Specifically, the baffle plate 44 has an arc structure, and the edge of the turntable 43 is provided with an upward protrusion. The protrusion is used to change the angle at which the descaling agent is thrown upward, so that it can be thrown a greater distance.

The outer wall of the container 3 has a rack 54 that meshes with the drive gear 52. When spraying the dephosphorizing agent, the motor 53 can be started first, and the drive gear 52 drives the rack 54 to move, allowing the container 3 to move upward inside the discharge pipe 13 and into the storage tank 1. This allows the dephosphorizing agent inside the storage tank 1 to enter the container 3, achieving one metering of the dephosphorizing agent. After the container 3 is filled with dephosphorizing agent, the container 3 is then lowered.

[0049] In this embodiment, a material feeding component 6 is provided above the interior of the container 3. The material feeding component 6 is at least used to ensure that the descaling agent inside the storage tank 1 can smoothly enter the interior of the container 3, so as to avoid blockage of the descaling agent.

[0050] Specifically, the feeding assembly 6 includes a motor 61 fixed to the top of the container 3. The motor 61 is located inside the lower part of the storage tank 1. The output shaft at the bottom of the motor 61 is equipped with a transmission shaft 62 located inside the container 3. Several blades 63 are arranged in upper and lower layers on the outer wall of the transmission shaft 62. When the container 3 is being filled, the feeding assembly 6 is activated, and the motor 61 starts to drive the blades 63 to rotate, allowing the descaling agent inside the storage tank 1 to smoothly enter the interior of the container 3, avoiding blockage of the descaling agent at the discharge pipe 13.

[0051] In this embodiment, an opening and closing module 7 is provided on one side of the bottom of the container 3. The opening and closing module 7 is used at least for opening and closing the bottom opening of the container 3.

[0052] Specifically, the opening and closing module 7 includes a motor 71 installed on the lower side of the outer wall of the container 3. A sealing plate 72 connected to the motor 71 is provided inside the lower part of the container 3. A shaft is provided in the middle of the sealing plate 72, and bearing seats 73 fixed to the outer walls of both sides of the container 3 are provided at both ends of the shaft. After the container 3 is filled once, the motor 71 is started. The motor 71 drives the sealing plate 72 to rotate, thereby opening the opening at the bottom of the container 3 and allowing the phosphorus removal agent inside the container 3 to fall onto the dispersion mechanism 4. The dispersion mechanism 4 is used to spray the phosphorus removal agent into the sewage tank.

[0053] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
