Description

Technical Field

[0001] This application relates to the technical field of disinfectant dosing equipment, and in particular to a disinfectant dosing device for sewage treatment. Background Technology

[0002] Wastewater treatment is an important part of environmental protection, and disinfection is a key step to ensure that the effluent quality meets the standards. At present, wastewater treatment plants generally use chemical disinfection methods, such as adding disinfectants such as chlorine, ozone or chlorine dioxide. With the increasing environmental protection requirements and the development of automation technology, the traditional experience-based dosing method can no longer meet the needs of precise control.

[0003] The existing announcement number is CN209307011U, entitled "A Disinfectant Dosing Device for Wastewater Treatment," which includes a treatment tank. A first support frame is fixedly connected to the bottom of the treatment tank, and a dispensing box is fixedly connected to the top of the first support frame. A second support frame is fixedly connected to the top of the first support frame. The beneficial effects of this invention are as follows: Disinfectant powder is poured from a dispensing funnel into the dispensing box. A motor drives a rotating shaft to rotate, and dispensing plates on both sides of the top of the shaft begin to push the powder in the dispensing box towards one end of a baffle to one side of the inner wall of the dispensing box. From there, a bolt pushes the bottom of the dispensing box, and then dispensing plates on both sides of the bottom of the shaft push the powder from one side of the bottom of the dispensing box into a dispensing trough. The powder then falls into the treatment tank, adding disinfectant to the wastewater discharged through the inlet pipe. Several stirring plates agitate the wastewater, ensuring thorough mixing of the wastewater and disinfectant powder in the treatment tank, achieving the disinfection effect.

[0004] Regarding the aforementioned technologies, the inventors discovered that when disinfecting the wastewater, manual labor is required to move the disinfectant from the dosing port in the treatment tank. Adding disinfectant multiple times involves a large amount of labor and cannot meet the need for continuous dosing of multiple batches of wastewater. Utility Model Content

[0005] To overcome the limitations of existing wastewater disinfection methods, which require manual handling of disinfectants to be added through the dosing port in the treatment tank, resulting in excessive labor and making it impossible to continuously add disinfectants to multiple batches of wastewater, this application provides a wastewater treatment disinfectant dosing device.

[0006] The wastewater treatment disinfectant dosing device provided in this application adopts the following technical solution: A wastewater treatment disinfectant dosing device includes a dosing component, a storage cylinder, and a feeding component. The dosing component includes a pusher shell and a storage shell. One end of the top surface of the pusher shell has a vertically penetrating dosing port, and the other end of the bottom surface of the pusher shell has a vertically penetrating dosing port. The storage shell is horizontally slidably inserted into the inside of the pusher shell, and both the upper and lower ends of the storage shell have vertically penetrating through slots. The storage cylinder is vertically positioned above the top surface of the pusher shell, and both the upper and lower ends of the storage cylinder are open. A discharge plate is horizontally fixed at the lower end of the inside of the storage cylinder, and there is a discharge gap between the discharge plate and the inner wall of the storage cylinder. The bottom end of the storage cylinder is connected and fixed to the dosing port of the pusher shell. The feeding component includes a screw cap and a stirring rod. The screw cap is threadedly assembled on the top of the storage shell, and the middle of the screw cap is vertically rotatably connected to the stirring rod. The bottom end of the stirring rod is penetrating the discharge plate, and a rotating plate is horizontally fixed at the bottom end of the stirring rod.

[0007] By adopting the above technical solution, when disinfectant needs to be added during wastewater treatment, the disinfectant is pre-stored in a storage cylinder. When the disinfectant needs to be added to the wastewater tank, the storage shell in the pusher of the dosing device first slides laterally, causing the storage shell to reach below the dosing port of the pusher. Then, the stirring rod in the middle of the screw cap rotates, causing the rotating plate to rotate below the dosing plate. There is a gap between the rotating plate and the dosing plate, and the disinfectant stored in the storage cylinder falls through the gap between the rotating plate and the dosing plate. The disinfectant falls into the storage shell through the dosing port at the top of the pusher. Then, the stirring rod in the middle of the screw cap rotates... The rotating rod drives the rotating plate to rotate below the discharge plate, closing the gap between the rotating plate and the discharge plate. This pulls the storage shell to slide laterally within the pusher shell, moving it to the dosing port of the pusher shell. Under the influence of gravity, the disinfectant in the storage shell is released into the sewage tank. Thus, the disinfectant is pre-stored in the storage shell. Then, a fixed amount of disinfectant is added to the sewage tank in batches using the dosing device. Therefore, when adding disinfectant to the sewage, there is no need to manually move the disinfectant from the dosing port in the treatment tank, avoiding the labor-intensive process of adding disinfectant multiple times and enabling continuous multi-batch sewage dosing.

[0008] Optionally, a horizontal plate is fixed to the top surface of the storage shell, and the horizontal plate is used to block the dosing port.

[0009] By adopting the above technical solution, a horizontally fixed plate on the top surface of the storage shell is used to block the dosing port. When the storage shell slides horizontally in the pusher shell, the horizontal plate blocks the dosing port of the pusher shell, preventing the disinfectant from falling into the pusher shell and causing waste of disinfectant.

[0010] Optionally, a hydraulic pusher is horizontally fixed at one end of the pusher shell near the drug dispensing port, and the output end of the hydraulic pusher is fixed at the end of the storage shell.

[0011] By adopting the above technical solution, in order to facilitate the lateral sliding of the storage shell in the pusher shell, when the disinfectant is dispensed, the pusher hydraulic rod is activated to push the storage shell to slide laterally in the pusher shell, and the disinfectant is delivered by sliding laterally in the pusher shell.

[0012] Optionally, the inner wall of the storage cylinder is provided with an internal thread, and the internal thread is assembled and connected with the screw cap thread. A feeding motor is vertically fixed on the top surface of the screw cap, and the output end of the feeding motor is fixed to the top of the stirring rod.

[0013] By adopting the above technical solution, the storage cylinder and the screw cap are connected by a threaded assembly, which facilitates the disassembly and processing of the screw cap in the storage cylinder. The feeding motor is started to drive the stirring rod to rotate on the screw cap, which is used to control the interval of disinfectant dosing.

[0014] Optionally, a feeding cylinder is provided on one side of the screw cap at an angle downwards, and the upper part of the feeding cylinder is connected and fixed to the screw cap, while the lower part of the feeding cylinder is vertically connected and fixed to the inlet port.

[0015] By adopting the above technical solution, when adding disinfectant to the storage cylinder, the disinfectant is added from the feed port of the feeding cylinder, and after being transported in the feeding cylinder, the disinfectant is added to the storage cylinder from the discharge end of the feeding cylinder, thus feeding the storage cylinder.

[0016] Optionally, a feeding screw is rotatably connected inside the feeding cylinder, and a feeding motor is fixed to the end of the feeding cylinder, with the output end of the feeding motor fixed to the end of the feeding screw.

[0017] By adopting the above technical solution, the feeding motor at the end of the feeding cylinder is started to drive the feeding screw to rotate. The rotating feeding screw drives the internal disinfectant of the feeding cylinder to be transported in the feeding cylinder. After that, the disinfectant is added to the storage cylinder from the discharge end of the feeding cylinder, and the storage cylinder is fed.

[0018] Optionally, two hole seats are symmetrically and vertically fixed on the top surface of the push shell, and a rod is horizontally arranged above the two hole seats. The rod is vertically slidably inserted into the two hole seats, and fixing screws for fixing are installed on the rod.

[0019] By adopting the above technical solution, a rod frame is vertically slidably inserted into two hole seats fixed on the top surface of the push shell. The rod frame is fixed to the sewage tank with fixing screws and is used to vertically hoist the dosing device onto the sewage tank.

[0020] Optionally, a support spring is vertically fixed on the hole seat, and the other end of the support spring is fixed to the bottom end of the slide bar of the rod frame. A damping rod is vertically fixed on the top surface of the hole seat, and the other end of the damping rod is fixed to the top surface of the rod frame.

[0021] By adopting the above technical solution, in order to ensure the stability of drug delivery during use, the vibration generated by the pushing and pulling of the drug delivery causes the pusher shell to slide vertically on the rod frame, compressing the deformation of the support spring to absorb the vibration, and then the deformation potential energy of the support spring is canceled by the damping rod, thus ensuring the stability of drug delivery by the pusher shell.

[0022] In summary, this application includes at least one of the following beneficial technical effects: When using it for wastewater treatment, if disinfectant needs to be added, the disinfectant is pre-stored in a storage cylinder. When the disinfectant needs to be added to the wastewater tank, the storage shell in the pusher shell of the sliding dosing device first slides laterally, causing the storage shell to reach below the dosing port of the pusher shell. Then, the stirring rod in the middle of the screw cap rotates, causing the rotating plate to rotate below the dosing plate. There is a gap between the rotating plate and the dosing plate. The disinfectant stored in the storage cylinder falls through the gap between the rotating plate and the dosing plate, and the disinfectant falls into the storage shell through the dosing port at the top of the pusher shell. Then, the pusher shell rotates... The rotating rod in the middle of the screw cap rotates, causing the rotating plate to rotate below the discharge plate and close the gap between the rotating plate and the discharge plate. This pulls the storage shell to slide laterally in the push shell, moving the storage shell to the dosing port of the push shell. Under the action of gravity, the disinfectant in the storage shell is released into the sewage tank. Thus, the disinfectant is pre-stored in the storage shell. Then, a fixed amount of disinfectant is added to the sewage tank in batches using the storage shell in the dosing device. Therefore, when adding disinfectant to the sewage, it is not necessary to manually move the disinfectant to the dosing port in the treatment tank, avoiding the large amount of labor required for multiple additions of disinfectant and enabling continuous multi-batch sewage dosing.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a wastewater treatment disinfectant dosing device. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A wastewater treatment disinfectant dosing device, characterized in that it includes a dosing component 1, a storage cylinder 2, and a feeding component 3. The dosing component 1 includes a push shell 11 and a storage shell 14. A dosing port 12 is vertically penetrating one end of the top surface of the push shell 11, and a dosing port 13 is vertically penetrating the other end of the bottom surface of the push shell 11. The storage shell 14 is horizontally slidably inserted into the interior of the push shell 11, and vertical through slots are vertically penetrating at both the upper and lower ends of the storage shell 14. The storage cylinder 2 is vertically positioned above the top surface of the push shell 11, and the storage cylinder 2... Both the top and bottom ends are open. The lower end of the storage cylinder 2 is horizontally fixed with a discharge plate 21, and there is a discharge gap between the discharge plate 21 and the inner wall of the storage cylinder 2. The bottom end of the storage cylinder 2 is connected and fixed to the discharge port 12 of the push shell 11. The feeding component 3 has a screw cap 31 and a stirring rod 32. The screw cap 31 is threadedly assembled on the top of the storage shell 14, and the middle of the screw cap 31 is vertically rotatably connected to the stirring rod 32. The bottom end of the stirring rod 32 passes through the discharge plate 21, and the bottom end of the stirring rod 32 is horizontally fixed with a rotating plate 33. When using disinfectant for wastewater treatment, the disinfectant is first stored in the storage cylinder 2. When the disinfectant needs to be added to the wastewater tank, the storage shell 14 in the push shell 11 of the dosing device 1 slides laterally, moving it below the discharge port 12 of the push shell 11. Then, the stirring rod 32 in the middle of the screw cap 31 rotates, causing the rotating plate 33 to rotate below the discharge plate 21. A gap exists between the rotating plate 33 and the discharge plate 21, allowing the disinfectant stored in the storage cylinder 2 to fall through this gap. The disinfectant then falls into the storage shell 14 through the discharge port 12 at the top of the push shell 11. Finally, the stirring rod 32 in the middle of the screw cap 31 is rotated... The rod 32 rotates, causing the rotating plate 33 to rotate below the material drop plate 21 and close the gap between the rotating plate 33 and the material drop plate 21. This pulls the storage shell 14 to slide laterally in the push shell 11, moving the storage shell 14 to the dosing port 13 of the push shell 11. Under the action of gravity, the disinfectant in the storage shell 14 is added to the sewage tank. Thus, the disinfectant is pre-stored in the storage shell 1 cylinder 2. Then, a fixed amount of disinfectant is added to the sewage tank in batches using the storage shell 14 in the dosing device 1. Therefore, when adding disinfectant to the sewage, it is not necessary to manually move the disinfectant from the dosing port in the treatment tank, avoiding the large amount of labor required for multiple additions of disinfectant and enabling continuous multi-batch sewage dosing.

[0027] Reference Figure 4A horizontal plate 15 is fixed to the top surface of the storage shell 14, and the horizontal plate 15 is used to block the dosing port 13. The horizontal plate 15, fixed to the top surface of the storage shell 14, blocks the dosing port 12 of the push shell 11 as the storage shell 14 slides laterally within the push shell 11, preventing disinfectant from falling into the push shell 11 and wasting disinfectant. A hydraulic push rod 16 is horizontally fixed to one end of the push shell 11 near the dosing port 12, and the output end of the hydraulic push rod 16 is fixed to the end of the storage shell 14. To facilitate the lateral sliding of the storage shell 14 within the push shell 11, when dispensing disinfectant, the hydraulic push rod 16 is activated to push the storage shell 14 laterally within the push shell 11, transporting the disinfectant for dosing.

[0028] Reference Figure 3 and Figure 5 The storage cylinder 2 has an internal thread 22 on its upper inner wall, which is threadedly connected to the screw cap 31. A feeding motor 34 is vertically fixed on the top surface of the screw cap 31, and the output end of the feeding motor 34 is fixed to the top of the stirring rod 32. The threaded connection between the storage cylinder 2 and the screw cap 31 facilitates the disassembly and processing of the screw cap 31 within the storage cylinder 2. Starting the feeding motor 34 drives the stirring rod 32 to rotate on the screw cap 31, controlling the interval between disinfectant additions. A feeding cylinder 35 is inclined downwards on one side of the screw cap 31, with its upper discharge end connected and fixed to the screw cap 31. A feed port is vertically connected and fixed to the lower part of the feeding cylinder 35. When adding disinfectant to the storage cylinder 2, the disinfectant is added through the feed port of the feeding cylinder 35. After being transported within the feeding cylinder 35, the disinfectant is added to the storage cylinder 2 through the discharge end of the feeding cylinder 35, thus feeding the storage cylinder 2. A feeding screw 36 is rotatably connected inside the feeding cylinder 35, and a feeding motor 34 is fixed to the end of the feeding cylinder 35, with the output end of the feeding motor 34 fixed to the end of the feeding screw 36. Starting the feeding motor 34 at the end of the feeding cylinder 35 drives the feeding screw 36 to rotate. The rotating feeding screw 36 spirally drives the disinfectant inside the feeding cylinder 35, transporting it through the cylinder. The disinfectant is then added to the storage cylinder 2 from the discharge end of the feeding cylinder 35, thus feeding the storage cylinder 2.

[0029] Reference Figure 3 and Figure 4Two symmetrically vertically fixed hole seats 17 are fixed on the top surface of the push shell 11, and a rod frame 18 is horizontally arranged above the two hole seats 17. The rod frame 18 is vertically slidably inserted into the two hole seats 17, and a fixing screw 181 is installed on the rod frame 18 for fixing. The rod frame 18 is vertically slidably inserted into the two hole seats 17 fixed on the top surface of the push shell 11. The rod frame 18 is fixed to the sewage tank with fixing screws 181 for vertically suspending the dosing device 1 in the sewage tank. A support spring 171 is vertically fixed on the hole seat 17, and the other end of the support spring 171 is fixed to the bottom end of the sliding rod of the rod frame 18. A damping rod 19 is vertically fixed on the top surface of the hole seat 17, and the other end of the damping rod 19 is fixed to the top surface of the rod frame 18. In order to ensure the stability of drug delivery during use, the vibration generated by pushing and pulling the drug delivery causes the pusher shell 11 to slide vertically on the rod frame 18, compressing the support spring 171 to deform and absorb the vibration. Then, the deformation potential energy of the support spring 171 is canceled by the damping rod 19, thus ensuring the stability of drug delivery by the pusher shell 11.

[0030] The implementation principle of the wastewater treatment disinfectant dosing device in this application embodiment is as follows: When wastewater treatment is carried out and disinfectant needs to be added, the feeding motor 34 at the end of the feeding cylinder 35 is started to drive the feeding screw 36 to rotate. The rotating feeding screw 36 drives the disinfectant inside the feeding cylinder 35 to be transported in the feeding cylinder 35. After the disinfectant is added to the storage cylinder 2 from the discharge end of the feeding cylinder 35, the storage cylinder 2 is filled with disinfectant. The disinfectant is stored in the storage cylinder 2 in advance. When the disinfectant needs to be added to the wastewater tank, in order to facilitate the lateral sliding of the storage shell 14 in the push shell 11, the push hydraulic rod 16 is started to push the storage shell 14 to slide laterally in the push shell 11. The disinfectant is transported and slid laterally in the push shell 11 for dosing. The push shell 11 in the sliding dosing part 1 The storage shell 14 slides laterally, causing it to reach below the dispensing port 12 of the push shell 11. The stirring rod 32 in the middle of the screw cap 31 rotates, causing the rotating plate 33 to rotate below the dispensing plate 21. There is a gap between the rotating plate 33 and the dispensing plate 21. The disinfectant stored in the storage cylinder 2 falls through the gap between the rotating plate 33 and the dispensing plate 21. The disinfectant falls into the storage shell 14 through the dispensing port 12 at the top of the push shell 11. Then, the stirring rod 32 in the middle of the screw cap 31 rotates, causing the rotating plate 33 to rotate below the dispensing plate 21 and close the gap between the rotating plate 33 and the dispensing plate 21. This pulls the storage shell 14 to slide laterally in the push shell 11, causing it to move to the dispensing port 13 of the push shell 11. Under the action of gravity, the disinfectant in the storage shell 14 is dispensed into the sewage tank.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
