Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment system with manual chemical dosing. Background Technology
[0002] With the acceleration of industrialization and the improvement of urbanization, the discharge of domestic sewage and industrial wastewater continues to increase. If the organic matter, heavy metals, suspended pollutants and nutrients contained in these wastewaters are discharged directly without effective treatment, it will cause eutrophication of water bodies, soil pollution, damage the ecological balance and threaten drinking water safety.
[0003] In existing technologies, the current wastewater treatment system using manual dosing involves the manual addition of chemicals (caustic soda, citric acid, PAC, PAM). This method is prone to errors in human judgment, leading to dosage deviations (±15%-20%). Overdosing can cause secondary pollution (such as excessive aluminum ions due to PAC residue). It also cannot respond in real time to changes in influent water quality (such as requiring more than 30 minutes to adjust when pH changes suddenly), resulting in unstable coagulation and sedimentation effects (turbidity fluctuations of up to ±10 NTU). A single station wastes approximately 50,000-80,000 yuan worth of chemicals annually, requires 2-3 dedicated personnel to operate in shifts, resulting in high labor costs, and the filter plates used for filtration require frequent manual cleaning, which is very troublesome. Utility Model Content
[0004] This utility model mainly provides a manual chemical dosing wastewater treatment system that can automatically control the dosage, automatically detect changes in water quality, and automatically replace and clean the filter plates.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a manual chemical dosing wastewater treatment system, comprising a chassis, a top cover bolted to the top of the chassis, a first motor mounted on the top of the top cover, the output end of the first motor penetrating the bottom of the top cover and fixed to a stirring shaft, multiple stirring blades fixed on the outer wall of the stirring shaft, a discharge pipe fixed to the bottom of the chassis, a metering pump installed inside the discharge pipe, a flow meter installed on the outer wall of the discharge pipe, a turbidity meter installed on the outer wall of the chassis, a main frame slidably placed inside the chassis, a secondary frame fixed to one end of the main frame, and filter plates rotatably connected to both the main frame and the secondary frame.
[0006] Preferably, a first connecting plate is fixed on the outer wall of the chassis, an electric push rod is installed at one end of the first connecting plate, and a second connecting plate is fixed at the output end of the electric push rod. The second connecting plate is fixed to the sub-frame. By operating the electric push rod, the second connecting plate can be moved, thereby moving the sub-frame so that the sub-frame seamlessly connects to the position of the main frame and pushes out the main frame, which is convenient for subsequent automatic cleaning.
[0007] Preferably, support plates are fixed at both ends of the casing, a water pump is installed at the top of the support plate, a connecting pipe is fixed at the bottom of the water pump, the bottom of the connecting pipe passes through the support plate and is fixed with a water outlet pipe, multiple nozzles are installed at the bottom of the water outlet pipe, the water outlet pipe is located above the filter plate, a water supply pipe is fixed at the top of the water pump, and a second flange is fixed to the outer wall of the top of the water supply pipe. By operating the water pump, water is drawn from the external water supply pipe connected to the water supply pipe, flows through the connecting pipe, enters the water outlet pipe, and is then sprayed out through the nozzles, enabling automatic rinsing of the removed filter plate.
[0008] Preferably, a second motor is installed in both the main frame and the sub-frame. The output ends of the two second motors are respectively fixed to the two filter plates. The operation of the second motors can drive the filter plates to rotate. During automatic cleaning of the filter plates, the rotation can improve the rinsing effect.
[0009] Preferably, a connecting cavity is provided at the top of the main frame inside the chassis. A connecting pipe is fixed on the inner wall of the connecting cavity, and a control valve is installed on the outer wall of the connecting pipe. By opening the control valve, the mixed medicine solution inside the chassis can enter the main frame or sub-frame through the connecting pipe for filtration.
[0010] Preferably, a feed pipe is fixed on both sides of the top of the top cover, and a first flange is fixed on the outer side of the top of each of the two feed pipes. Support legs are fixed at the four corners of the bottom of the machine. The two feed pipes can be connected to the external drug feeding mechanism and water feeding mechanism respectively, which facilitates subsequent mixing in the machine.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the dosage of chemicals poured into the sewage tank through the discharge pipe can be precisely controlled by setting up a flow meter and a metering pump, saving 15%-20% of the chemicals. With the turbidity meter, during use, simply placing the output end of the turbidity meter into the sewage tank beforehand allows for automatic detection of changes in turbidity, ensuring that the effluent meets environmental standards. When the filter plates need cleaning, simply operating the electric push rod moves the second connecting plate, which in turn moves the sub-frame, seamlessly connecting it to the main frame and pushing the main frame out. Then, the water pump operates, allowing water from the external water supply pipe connected to the water supply pipe to flow through the connecting pipe into the outlet pipe, and then spraying it out through the nozzles, automatically rinsing the removed filter plates. Simultaneously, the operation of the second motor rotates the filter plates, resulting in better rinsing. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0016] Please see Figures 1-4This utility model provides a technical solution: a manual chemical dosing wastewater treatment system, including a casing 1. A top cover 2 is bolted to the top of the casing 1. A first motor 3 is mounted on the top of the top cover 2. The output end of the first motor 3 passes through the bottom end of the top cover 2 and is fixed to a stirring shaft 4. Multiple stirring blades 5 are fixed on the outer wall of the stirring shaft 4. A discharge pipe 26 is fixed to the bottom of the casing 1. A metering pump 27 is installed inside the discharge pipe 26. A flow meter 28 is installed on the outer wall of the discharge pipe 26. A turbidity meter 8 is installed on the outer wall of the casing 1. A main frame 9 is slidably placed inside the casing 1. A secondary frame 10 is fixed to one end of the main frame 9. Filter plates 1 are rotatably connected inside both the main frame 9 and the secondary frame 10. 2. After the medicine and water enter the casing 1, the operation of the first motor 3 drives the stirring shaft 4 to rotate, which in turn drives the stirring blade 5 to rotate, so that the medicine and water are fully mixed. The mixed medicine solution enters the connecting pipe 17 through the opening of the control valve 18, and finally enters the corresponding main frame 9 or secondary frame 10. It is filtered by the filter plate 12. The filtered medicine solution enters the discharge pipe 26. The discharge volume is precisely controlled by the metering pump 27 and the flow meter 28. With the setting of the turbidity meter 8, when in use, it is only necessary to place the output end of the turbidity meter 8 into the sewage tank in advance to automatically detect the change of turbidity in the sewage tank, ensuring that the effluent meets the environmental protection standards.
[0017] like Figure 1-4 As shown, a first connecting plate 13 is fixed on the outer wall of the casing 1. An electric push rod 14 is installed at one end of the first connecting plate 13. A second connecting plate 15 is fixed at the output end of the electric push rod 14. The second connecting plate 15 is fixed to the sub-frame 10. By operating the electric push rod 14, the second connecting plate 15 can be moved, thereby moving the sub-frame 10 so that the sub-frame 10 can seamlessly connect to the position of the main frame 9 and push the main frame 9 out, which is convenient for subsequent automatic cleaning.
[0018] like Figure 1-4 As shown, support plates 19 are fixed at both ends of the casing 1. A water pump 20 is installed at the top of the support plate 19. A connecting pipe 21 is fixed at the bottom of the water pump 20. The bottom of the connecting pipe 21 passes through the support plate 19 and is fixed with an outlet pipe 22. Multiple nozzles 23 are installed at the bottom of the outlet pipe 22. The outlet pipe 22 is located above the filter plate 12. A water supply pipe 24 is fixed at the top of the water pump 20. A second flange 25 is fixed on the outer wall of the top of the water supply pipe 24. By operating the water pump 20, water is supplied from the external water supply pipe connected to the water supply pipe 24 through the connecting pipe 21 and enters the outlet pipe 22. The water is then sprayed out through the nozzles 23, which can automatically rinse the removed filter plate 12.
[0019] like Figure 1-4As shown, a second motor 11 is installed in both the main frame 9 and the sub-frame 10. The output ends of the two second motors 11 are fixed to the two filter plates 12 respectively. The operation of the second motors 11 can drive the filter plates 12 to rotate. When the filter plates 12 are automatically cleaned, their rotation can improve the rinsing effect.
[0020] like Figure 1-4 As shown, a connecting cavity 16 is provided at the top of the main frame 9 inside the casing 1. A connecting pipe 17 is fixed on the inner wall of the connecting cavity 16. A control valve 18 is installed on the outer wall of the connecting pipe 17. By opening the control valve 18, the mixed medicine solution in the casing 1 can enter the main frame 9 or the secondary frame 10 through the connecting pipe 17 for filtration.
[0021] like Figure 1-4 As shown, feed pipes 6 are fixed on both sides of the top of the top cover 2, and first flanges 7 are fixed on the outer sides of the top of the two feed pipes 6. Support legs 29 are fixed at the four corners of the bottom of the machine box 1. The two feed pipes 6 can be connected to the external drug feeding mechanism and water feeding mechanism respectively, which facilitates subsequent mixing in the machine box 1.
[0022] The device's operation and working principle are as follows: During use, the device connects to external drug and water inlet mechanisms via two feed pipes 6. Drugs and water enter the casing 1 through these pipes. The first motor 3 drives the stirring shaft 4, which in turn rotates the stirring blades 5, ensuring thorough mixing of the drugs and water. The mixed solution then flows through the control valve 18 into the connecting pipe 17, and finally into the corresponding main frame 9 or secondary frame 10. It is then filtered by the filter plate 12. The filtered solution enters the discharge pipe 26, where the discharge volume is precisely controlled by the metering pump 27 and flow meter 28. The turbidity meter 8 is used; during operation, simply pre-set the turbidity meter 8... When the output end is placed in the sewage tank, it can automatically detect changes in turbidity in the sewage tank to ensure that the effluent meets environmental protection standards. When the filter plate 12 needs to be cleaned, the operation of the electric push rod 14 can drive the second connecting plate 15 to move, thereby driving the sub-frame 10 to move, so that the sub-frame 10 seamlessly connects to the position of the main frame 9 and pushes out the main frame 9. Then, through the operation of the water pump 20, water from the external water supply pipe connected to the water supply pipe 24 flows through the connecting pipe 21 into the water outlet pipe 22, and is sprayed out through the nozzle 23, which can automatically rinse the removed filter plate 12. At the same time, through the operation of the second motor 11, the filter plate 12 can be rotated, resulting in a better rinsing effect.
[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
