Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a carbon source replenishment device for wastewater treatment plants. Background Technology
[0002] In recent years, with the increasing awareness of environmental protection, sewage treatment has become one of the unavoidable and urgent ecological and environmental problems in people's daily lives. In sewage treatment, the reduction of COD and TN, the main pollutants, depends on the action of nitrifying and denitrifying bacteria. If the BOD content of the sewage treatment plant influent is relatively low, the growth of denitrifying bacteria will be limited, the denitrification capacity will be weakened, and the phosphorus and nitrogen removal capacity of the biological treatment section will not be able to meet the requirements of pollutant removal. At present, the vast majority of sewage treatment in my country has adopted the measure of adding external carbon sources, mainly methanol and sodium acetate, to improve the removal efficiency.
[0003] Currently, wastewater treatment plants typically add carbon sources to wastewater ponds by manually sprinkling or using tools, depending on the scale of the wastewater being treated. However, the sprinkled carbon sources tend to clump together, resulting in uneven distribution of the carbon sources on the wastewater. This leads to incomplete removal of pollutants in areas of wastewater that are not in contact with the carbon sources, thus affecting the overall treatment efficiency of the wastewater treatment plant. Therefore, it is necessary to design a carbon source replenishment device for wastewater treatment plants to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a carbon source replenishment device for wastewater treatment plants to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a carbon source replenishment device for a wastewater treatment plant, comprising:
[0006] The mounting base has a support column fixedly welded to its top wall. A connecting column is provided on the support column, and a mounting rod is fixedly welded to the top of the connecting column. Multiple equidistantly distributed storage cylinders are installed on the mounting rod. A discharge pipe is fixedly installed at the bottom of each storage cylinder, and a control valve is installed on the discharge pipe. A material dispensing box is fixedly welded to the bottom wall of the mounting rod. The bottom end of the discharge pipe extends through the mounting rod into the inner cavity of the material dispensing box. A material distribution plate is provided on the material dispensing box, and several evenly distributed leakage holes are opened on the material distribution plate.
[0007] Preferably, the top wall of the support column is provided with an installation groove, the connecting column is rotatably mounted on the support column through a set bearing, a drive motor is fixedly installed in the installation groove, the output end of the drive motor is connected to a rotating rod, and the top end of the rotating rod is fixedly installed on the bottom wall of the connecting column.
[0008] Preferably, a pair of fixed seats are fixedly welded to the front and rear side walls of the material dispensing box, and two pairs of connecting rods are fixedly welded to the material distribution plate, with the two pairs of connecting rods slidably connected to the two pairs of fixed seats respectively.
[0009] Preferably, a disc is fixedly welded onto the support column, and multiple annularly distributed hemispheres are fixedly welded onto the top wall of the disc. A push rod is fixedly welded onto the bottom wall of the material distribution plate, and a trigger ball is fixedly welded to the bottom end of the push rod.
[0010] Preferably, a cylinder cover is threaded onto the top of the storage cylinder, and a handle is fixedly installed on the cylinder cover.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. When it is necessary to add carbon source to sewage, the drive motor can be turned on. The drive motor drives the connecting column to rotate at low speed on the support column through the rotating rod, thereby driving the installation rod to rotate around the support column. During the rotation of the installation rod, the powdered carbon source in the storage cylinder is discharged into the distribution plate of the spreading box through the discharge pipe, and falls into the sewage through the leakage hole, so as to achieve the effect of spreading carbon source in all directions in the sewage tank.
[0013] 2. During the material spreading process, the trigger ball of this utility model can sequentially contact multiple hemispheres. When it collides with a hemisphere, the trigger ball will be squeezed and move upward, driving the push rod to push the material distribution plate upward. When the trigger ball rotates past the top of the hemisphere, the material distribution plate will move downward due to its own gravity. This cycle allows the material distribution plate to shake up and down repeatedly when the mounting rod rotates. This not only facilitates material leakage through the leakage hole and avoids clogging, but also disperses the powdered carbon source on the material distribution plate, expanding the spreading range and improving the uniformity of spreading.

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.
[0019] Please see Figure 1-3 This utility model provides a technical solution: a carbon source replenishment device for a wastewater treatment plant, comprising:
[0020] Mounting base 1, a support column 2 is fixedly welded to the top wall of mounting base 1, a connecting column 3 is provided on the support column 2, a mounting rod 4 is fixedly welded to the top of the connecting column 3, a plurality of equidistantly distributed storage cylinders 5 are installed on the mounting rod 4, a discharge pipe 6 is fixedly installed at the bottom end of the storage cylinder 5, a control valve is installed on the discharge pipe 6, a spreading box 7 is fixedly welded to the bottom wall of mounting rod 4, the bottom end of the discharge pipe 6 extends through the mounting rod 4 into the inner cavity of the spreading box 7, a distributing plate 8 is provided on the spreading box 7, and a plurality of evenly distributed leakage holes 9 are opened on the distributing plate 8.
[0021] The top wall of the support column 2 is provided with an installation groove 16. The connecting column 3 is rotatably mounted on the support column 2 through a bearing. A drive motor 17 is fixedly installed in the installation groove 16. The output end of the drive motor 17 is connected to a rotating rod 18. The top end of the rotating rod 18 is fixedly mounted on the bottom wall of the connecting column 3. After the drive motor 17 is started, it can drive the rotating rod 18, which drives the connecting column 13 to rotate on the support column 2, thereby driving the installation rod 4 to rotate around the support column 2.
[0022] A pair of fixed seats 10 are fixedly welded to the front and rear side walls of the material dispensing box 7. Two pairs of connecting rods 11 are fixedly welded to the material dispensing plate 8. The two pairs of connecting rods 11 are slidably connected to the two pairs of fixed seats 10 respectively. The material dispensing plate 8 can move up and down in the material dispensing box 7 through the sliding cooperation between the connecting rods 11 and the fixed seats 10.
[0023] A disc 12 is fixedly welded to the support column 2. Multiple annularly distributed hemispheres 13 are fixedly welded to the top wall of the disc 12. A push rod 14 is fixedly welded to the bottom wall of the distribution plate 8. A trigger ball 15 is fixedly welded to the bottom end of the push rod 14. When the mounting rod 4 rotates, it can drive the trigger ball 15 to rotate around the support column 2. During the rotation, when the trigger ball 15 collides with the hemispheres 13, the trigger ball 15 will be squeezed and move upward, driving the push rod 14 to push the distribution plate 8 upward. When the trigger ball 15 rotates past the top of the hemispheres 13, the distribution plate 8 will move downward due to its own gravity. This cycle allows the distribution plate 8 to shake up and down repeatedly when the mounting rod 4 rotates. This not only facilitates the leakage of material from the leakage hole 9 and avoids clogging, but also disperses the powdered carbon source on the distribution plate 8, expanding the spreading range.
[0024] The top of the storage cylinder 5 is threaded with a cylinder cover 19, and a handle 20 is fixedly installed on the cylinder cover 19. The cylinder cover 19 can prevent rainwater from entering.
[0025] Working Principle: In use, the mounting base 1 of this device is fixedly installed in the middle of the sewage tank, ensuring that the water level in the tank does not exceed that of the disc 12. Powdered carbon source is sequentially added to multiple storage cylinders 5. When it is necessary to replenish the carbon source in the sewage, the drive motor 17 is turned on. The drive motor 17 drives the connecting column 13 to rotate at low speed on the support column 2 via the rotating rod 18, thereby causing the mounting rod 4 to rotate around the support column 2. During the rotation of the mounting rod 4, the powdered carbon source in the storage cylinder 5 is discharged through the discharge pipe 6 onto the distribution plate 8 of the spreading box 7, and falls into the sewage through the leakage hole 9, thus achieving the goal of treating the sewage. The effect of omnidirectional carbon source dispensing in the water tank is achieved by the set-up trigger ball 15, which can contact multiple hemispheres in sequence during the dispensing process. When it collides with the hemisphere 13, the trigger ball 15 will be squeezed and move upward, driving the push rod 14 to push the dispensing plate 8 upward. When the trigger ball 15 rotates past the top of the hemisphere 13, the dispensing plate 8 will move downward due to its own gravity. This cycle allows the dispensing plate 8 to shake up and down repeatedly when the mounting rod 4 rotates. This not only facilitates the leakage of material through the leakage hole 9 and avoids clogging, but also disperses the powdered carbon source on the dispensing plate 8, expands the dispensing range, and improves the uniformity of dispensing.
