Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an intelligent flocculant dosing device for integrated wastewater treatment equipment. Background Technology

[0002] Integrated wastewater treatment equipment is a complete set of equipment that integrates multiple wastewater treatment units (such as sedimentation, biochemical treatment, filtration, disinfection, etc.) into a compact device, suitable for small and medium-scale wastewater treatment scenarios. Some solutions for integrated wastewater treatment equipment have been disclosed in related technologies. For example, the authorized patent document with application number CN202322264410.4 discloses an integrated wastewater treatment device including a bar screen, a treatment tank, a filter tank, and a support frame. The treatment tank has an inlet pipe on one side. The interior of the treatment tank is divided into a screening zone and a sedimentation zone. The bar screen is located within the screening zone, and a sieve plate is provided between the screening zone and the sedimentation zone. The bar screen is positioned close to the sieve plate. A stirring mechanism is provided in the sedimentation zone, including a first stirrer and a second stirrer. The first and second stirrers rotate in opposite directions, and a transmission component connects the first and second stirrers. The transmission component is located at the top of the treatment tank. A sludge removal mechanism is located at the bottom of the sedimentation zone, and a flocculant tank is located at the top of the sedimentation zone.

[0003] In the above-mentioned solution, the flocculant in the flocculant tank is discharged into the treatment tank, and then the flocculant and sewage are mixed evenly by a stirring mechanism. However, the flocculant tank is fixed in position on the treatment tank, which causes the flocculant to be discharged into the treatment tank from a fixed position. This results in low dispersion of the flocculant in the sewage during the dosing process, making it difficult to achieve rapid and uniform mixing between the flocculant and the sewage. In addition, the concentration of the agent at the discharge port of the flocculant tank is too high, which can easily reduce the utilization rate of the flocculant if rapid dispersion cannot be achieved. Therefore, the flocculant dosing device in the above-mentioned solution has the problems of low efficiency in uniform mixing of flocculant and sewage and low flocculant utilization rate. Based on this, this application proposes an intelligent flocculant dosing device for an integrated sewage treatment equipment. Utility Model Content

[0020] 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.

[0021] This utility model provides embodiments: Please refer to Figures 1-5The integrated wastewater treatment equipment includes an intelligent flocculant dosing device, comprising a flocculant storage tank 1 containing flocculant that can be directly added to the integrated wastewater treatment equipment. A level gauge 21 is installed on the flocculant storage tank 1 to monitor the flocculant content in the tank in real time and upload the monitoring results to the controller of this application. The controller analyzes the monitoring results so that staff can replenish the flocculant in a timely manner. A flocculant replenishment port is located on the top of the flocculant storage tank 1, and the port is sealed with a sealing cap.

[0022] The inner cavity of the flocculant storage tank 1 is provided with a separation discharge structure. The separation discharge structure includes a fixed plate 5 that is movably connected to the inner cavity of the flocculant storage tank 1. The fixed plate 5 is connected to the flocculant storage tank 1 through a lifting structure 2. The lifting structure 2 can be an electric telescopic rod in the prior art. Under the action of the lifting structure 2, the height of the fixed plate 5 in the flocculant storage tank 1 can be changed. The outer ring of the fixed plate 5 is uniformly provided with through holes. Under the action of the through holes, the flocculant will not affect the movement of the fixed plate 5.

[0023] A driving assembly is provided on the top of the fixed plate 5, and a movable plate 6 is movably connected to the bottom of the fixed plate 5. The movable plate 6 is driven by the driving assembly. In one embodiment of this application, the driving assembly includes a servo motor 8. A protective cover 7 is connected to the middle of the top of the fixed plate 5, and the servo motor 8 is fixedly connected to the inner cavity of the protective cover 7. The output shaft end of the servo motor 8 is connected to the middle of the top of the movable plate 6 through a reducer. When the servo motor 8 rotates, it can drive the movable plate 6 to rotate. Another through hole is evenly provided on the outer ring of the movable plate 6, and under the action of the servo motor 8, the other through hole and the through hole can be in a staggered state or an overlapping state. When the through hole on the fixed plate 5 and the through hole on the movable plate 6 are in an overlapping state, The fixed plate 5 and the movable plate 6 move within the flocculant storage tank 1. When the through holes on the fixed plate 5 and the movable plate 6 are misaligned, the structure formed by the fixed plate 5 and the movable plate 6 creates a partition plate, dividing the flocculant storage tank 1 into two parts. Under the action of the lifting structure, the downward movement of the partition plate allows the flocculant in the flocculant storage tank 1 to be discharged through the flocculant storage tank outlet. Thus, in actual use, the controller of this application controls the operation of the lifting structure according to the flocculant dosage required by the integrated wastewater treatment equipment. The lifting structure drives the fixed plate 5 and the movable plate 6 to move until the volume of flocculant in the area below the partition plate meets the actual requirements. In use, this application can achieve intelligent quantitative discharge.

[0024] A flocculant storage tank 1 has an isolation chamber 3 at its bottom. A stirring structure and a dosing structure are located in the middle of the isolation chamber 3. The stirring structure includes alternating transmission pipes 4 and stirring blades. The top of the stirring structure is movably connected to the isolation chamber 3. A drive structure is located inside the isolation chamber 3. In one embodiment of this application, the drive structure includes a servo motor 11. The output shaft of the servo motor 11 is fixedly connected to a gear 12 via a reducer. A gear 13 is fixedly connected to the top of the stirring structure. Gear 12 and gear 13 are meshed. When the servo motor 11 rotates, it drives the connected gear 12 to rotate. Gear 12, through the meshing gear 13, drives the stirring structure to rotate. The rotation of the stirring structure causes the stirring blades to rotate, which in turn agitates the surrounding wastewater, increasing the wastewater flow rate. The stirring blades include two blades 10, with one side of each blade 10 connected by a connecting block 22.

[0025] The dosing structure includes a flocculant delivery pipe 20 that is movably connected to the inner cavity of the transmission pipe 4. A hollow ring 14 is fixedly connected to the top of the transmission pipe 4. The inner wall of the hollow ring 14 is connected to a servo motor 15. The output shaft of the servo motor 15 is connected to the top of the flocculant delivery pipe 20 through a reducer. When the servo motor 15 rotates, it can drive the flocculant delivery pipe 20 to rotate. When the stirring structure rotates, it can drive the dosing structure to rotate, thereby making the stirring structure and the dosing structure relatively stationary.

[0026] Hollow drain plates 9 are evenly arranged on the outer wall of the flocculant delivery pipe 20. The hollow drain plates 9 are located between the two blades 10 of the stirring blade. Figure 4 As shown, a connecting hole one is provided on the side wall of the flocculant delivery pipe 20, and a connecting hole two is provided on the inner wall of the hollow drain plate 9. The connecting hole one and the connecting hole two are in an overlapping state. Under the action of the connecting hole one and the connecting hole two, the inner cavity of the hollow drain plate 9 is connected to the inner cavity of the flocculant delivery pipe 20. Flocculant discharge holes 19 are provided at the top and bottom of the inner cavity of the hollow drain plate 9.

[0027] As described above, under the action of the servo motor 15, the position of the hollow drain plate 9 can be changed. Furthermore, during the addition of flocculant, the hollow drain plate 9 and the impeller 10 rotate together at a fixed offset angle, facilitating the discharge of flocculant from the hollow drain plate 9. When no flocculant is added, the hollow drain plate 9 and the stirring impeller are in an overlapping state. Figures 1 to 4 As shown, the blade 10 blocks the flocculant discharge hole 19 at this time to prevent the flocculant discharge hole 19 from being blocked when impurities in the sewage flocculate. Furthermore, the dimensions of the stirring structure and the dosing structure can be set according to the size of the sewage chamber of the integrated sewage treatment equipment to which they are applied, and are not limited here.

[0028] The inner cavity of the hollow ring 14 is connected to the inner cavity of the flocculant delivery pipe 20 via a connecting pipe 16. The connecting pipe 16 is a telescopic pipe, which can be a corrugated pipe. One end of the connecting pipe 16 extends into the inner cavity of the hollow ring 14, and the other end extends into the inner cavity of the flocculant delivery pipe 20. A connecting ring 18 is movably sleeved on the outer wall of the hollow ring 14. The outer wall of the inner cavity of the hollow ring 14 is evenly provided with mesh holes. The inner cavity of the hollow ring 14 is connected to the connecting ring 18 through the mesh holes. The inner cavity of 8 is connected, and the outer wall of the connecting ring 18 is connected to the connecting pipe 2 17. The top of the connecting pipe 2 17 extends to the inner cavity of the flocculant storage tank 1, and the top of the connecting pipe 2 17 is at the same height as the top of the inner cavity of the flocculant storage tank 1. The inner cavity of the connecting ring 18 is connected to the inner cavity of the flocculant storage tank 1 through the connecting pipe 2 17. The connecting ring 18 is connected to the flocculant storage tank 1 through the connecting pipe 2 17, and an electric ball valve is provided at one end of the connecting pipe 2 17.

[0029] As described above, when the electric ball valve is in the open state, the flocculant in the flocculant storage tank 1 enters the inner cavity of the connecting ring 18 through the connecting pipe 17. The flocculant in the inner cavity of the connecting ring 18 enters the inner cavity of the hollow ring 14 through the mesh. The flocculant in the inner cavity of the hollow ring 14 enters the inner cavity of the flocculant delivery pipe 20 through the connecting pipe 16. The flocculant in the inner cavity of the flocculant delivery pipe 20 enters the inner cavity of the hollow drain plate 9 and mixes with the sewage through the flocculant discharge hole 19.

[0030] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0031] In summary: When the intelligent flocculant dosing device of this integrated sewage treatment equipment is in use, the isolation chamber 3 is fixed to the existing integrated sewage treatment equipment. The end of the stirring structure away from the isolation chamber 3 is located inside the integrated sewage treatment equipment. When flocculant needs to be added, the controller of the device controls the lifting structure 2 to work according to the flocculant dosage required by the integrated sewage treatment equipment. The lifting structure 2 drives the fixed plate 5 and the movable plate 6 to move until the flocculant dosage below the movable plate 6 meets the requirements. At this time, the servo motor 8 works and drives the movable plate 6 to rotate until the through hole on the movable plate 6 is misaligned with the through hole on the fixed plate 5. At this time, the movable plate 6 and the fixed plate 5 form a partition plate, and the flocculant dosage below the movable plate 6 is fixed. After the flocculant is metered, servo motor 15 drives the flocculant delivery pipe 20 to rotate, and the flocculant delivery pipe 20 drives the hollow drain plate 9 to rotate until the flocculant discharge hole 19 and the blade plate 10 are misaligned. The electric ball valve is in the open state, and the lifting structure drives the partition plate to move down. Under the action of gravity and the squeezing force brought about by the downward movement of the partition plate, the flocculant is discharged along the connecting pipe 17, connecting ring 18, hollow ring 14, connecting pipe 16, flocculant delivery pipe 20, hollow drain plate 9 and flocculant discharge hole 19. The flocculant mixes with the sewage. During the flocculant addition process, servo motor 11 drives the stirring structure to rotate, and the stirring structure drives the addition structure to rotate. The stirring blade and the hollow drain plate 9 simultaneously agitate the sewage and change the addition position of the flocculant, so that the flocculant is highly dispersed during addition, ensuring the effect of the flocculant and improving the mixing speed of sewage and flocculant.
