Description

Technical Field

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

[0002] Domestic sewage refers to wastewater generated by residents in their daily lives, mainly from kitchens, bathrooms, laundry rooms, and toilets. Its composition is complex, containing a large number of impurities and suspended solids. If discharged directly without treatment, it will cause serious pollution to water bodies, soil, and the ecological environment.

[0003] Existing wastewater treatment devices include a treatment tank, with a wastewater inlet pipe connected to one side of the top and a chemical feed pipe connected to the other side of the top. A filter screen is installed inside the treatment tank. During wastewater treatment, wastewater enters the treatment tank through the wastewater inlet pipe, and chemical agents are added through the chemical feed pipe to mix with the wastewater. The agents react with suspended solids and colloids in the wastewater to form larger flocs. These flocs settle onto the filter screen under gravity. The filter screen effectively intercepts impurities and flocs, allowing clean water to be discharged through the drain pipe.

[0004] Existing wastewater treatment devices typically add chemicals to the wastewater all at once, rather than dispensing them intermittently and quantitatively. This results in uneven chemical concentrations in some areas and insufficient concentrations in others, hindering the effective treatment of pollutants and preventing them from fully contacting and reacting with the wastewater. Furthermore, adding chemicals all at once may lead to some chemicals not being fully utilized during the reaction, resulting in waste. Therefore, an integrated wastewater treatment device is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes an integrated sewage treatment device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An integrated sewage treatment device of this utility model includes a treatment tank and a filter tank. A sewage inlet pipe is connected to one side of the top of the treatment tank, and a fixing frame is fixed to the other side of the top of the treatment tank. A chemical storage hopper is fixed to the top of the fixing frame, and a guide pipe is fixed to the bottom of the fixing frame, with the guide pipe positioned directly below the chemical storage hopper. A first motor is installed on the top side of the treatment tank, and a rotating disk is installed at the output end of the first motor. The rotating disk is positioned between the chemical storage hopper and the guide pipe, and a guide hole is provided on the rotating disk. The lower port of the chemical storage hopper is directly... The diameter of the feed pipe is the same as the diameter of the guide hole. When the agent is added to the sewage, the first motor operates to rotate the rotating disk, which in turn rotates the guide hole. When the guide hole rotates to coincide with the port of the agent storage hopper and the port of the feed pipe, the agent in the agent storage hopper will be put into the sewage in the treatment tank through the feed pipe. Through the rotation of the rotating disk and the design of the guide hole, the intermittent quantitative addition of the agent is realized, which helps to ensure that the agent and the pollutants in the sewage are fully contacted and reacted, thereby improving the treatment effect. At the same time, it avoids the phenomenon of wasting the agent due to the insufficient utilization of some agents during the reaction process caused by adding too much agent at one time.

[0007] Preferably, a bracket is fixed between the inner walls of both sides of the treatment tank. A second motor is installed on the top side of the treatment tank. The output end of the second motor is connected to a rotating rod, and the bottom end of the rotating rod passes through the bracket. Multiple horizontal stirring rods are fixed on the rotating rod, and multiple vertical stirring rods are fixed on each horizontal stirring rod. A scraper is fixed to the bottom end of the rotating rod, and the scraper is in contact with the outer surface of the first filter screen. When treating wastewater, during intermittent addition of chemicals, the second motor operates, causing the rotating rod to drive the horizontal stirring rods, vertical stirring rods, and scraper to rotate. The rotation and stirring of the horizontal and vertical stirring rods ensures the uniform distribution of the chemicals in the wastewater, allowing the chemicals to fully contact and react with the wastewater, thus improving the treatment effect. The rotation of the scraper removes the deposits on the surface of the first filter screen, maintaining the permeability of the filter screen and preventing clogging that could affect the treatment efficiency.

[0008] Preferably, a first positioning slot is provided on the inner wall of one side of the processing box, and a first through-hole is provided on the other side of the processing box. A first filter screen is inserted into the first positioning slot and the first through-hole. A first push-pull plate is fixed to one side of the first filter screen, and a first handle is mounted on the first push-pull plate. When using the device, the first filter screen can be easily replaced by cooperating with the first positioning slot and the first through-hole. Regular replacement of the filter screen can prevent clogging and ensure the subsequent filtration effect.

[0009] Preferably, a second positioning slot is provided on the inner wall of one side of the filter box, and a second opening is provided on the other side of the filter box. The second positioning slot and the second opening cooperate to insert a second filter screen plate. A second push-pull plate is fixed to one side of the second filter screen plate, and a second handle is mounted on the second push-pull plate. When using the device, the first filter screen plate can be easily replaced by cooperating with the first positioning slot and the first opening. Regular replacement of the filter screen can prevent clogging and ensure the subsequent filtration effect.

[0010] Preferably, a pump body is mounted on the top side of the filter box. The inlet of the pump body is connected to a water pumping pipe, and the other end of the water pumping pipe is connected to the bottom of the treatment box. The outlet of the pump body is connected to an outlet pipe, and the other end of the outlet pipe is located inside the filter box. A drain pipe is connected to the bottom side of the filter box. When treating sewage, the agent reacts with the suspended solids and colloids in the sewage to form larger flocs. The flocs settle onto the first filter screen under gravity. Through the action of the first filter screen, impurities and flocs can be intercepted. The pump body is started, so that the water after the first filtration flows into the filter box through the outlet pipe. Through the action of the second filter screen, fine impurities in the water can be further intercepted. Through staged filtration, the sewage treatment effect is improved.

[0011] The advantages of this utility model are:

[0012] 1. When adding chemicals to wastewater, the present invention uses a first motor to rotate a rotating disk, which in turn rotates the guide hole. When the guide hole rotates to coincide with the port of the chemical storage hopper and the port of the feed pipe, the chemicals in the chemical storage hopper will be fed into the wastewater in the treatment tank through the feed pipe. Through the rotation of the rotating disk and the design of the guide hole, the intermittent quantitative addition of chemicals is achieved, which helps to ensure that the chemicals fully contact and react with the pollutants in the wastewater, thereby improving the treatment effect. At the same time, it avoids the phenomenon of waste caused by adding too much chemicals at one time, which would result in some chemicals not being fully utilized during the reaction process.

[0013] 2. In the treatment of wastewater, when the agent is intermittently added, the second motor drives the rotating rod to rotate the horizontal stirring rod, the vertical stirring rod, and the scraper. The rotation of the horizontal and vertical stirring rods ensures the uniform distribution of the agent in the wastewater, allowing the agent to fully contact and react with the wastewater, thus improving the treatment effect. The rotation of the scraper removes the deposits on the surface of the first filter screen, maintaining the permeability of the filter screen and preventing clogging that could affect the treatment efficiency.

[0014] 3. When using this device, the plug-in design makes it easy to replace the filter screen. Regular replacement of the filter screen can prevent clogging and ensure the subsequent filtration effect. Attached Figure Description

[0023] 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 scope of protection of the present utility model.

[0024] Please see Figure 1-5As shown, an integrated wastewater treatment device includes a treatment tank 1 and a filter tank 2. A wastewater inlet pipe 3 is connected to one side of the top of the treatment tank 1, and a fixing frame 4 is fixed to the other side of the top of the treatment tank 1. A chemical storage hopper 5 is fixed to the top of the fixing frame 4, and a guide pipe 6 is fixed to the bottom of the fixing frame 4, positioned directly below the chemical storage hopper 5. A first motor 7 is installed on the top side of the treatment tank 1, and a rotating disk 8 is installed at the output end of the first motor 7, positioned between the chemical storage hopper 5 and the guide pipe 6. A guide hole 9 is provided on the rotating disk 8. The diameter of the lower port of the chemical storage hopper 5, the diameter of the guide pipe 6, and the diameter of the guide hole 9 are the same. During operation, chemicals need to be added to the wastewater for treatment. After the wastewater enters the treatment tank 1 through the wastewater inlet pipe 3, the first motor 7 operates, causing the rotating disk 8 to rotate, which in turn causes the guide hole 9 to rotate as well. When the guide hole 9 rotates to coincide with the port of the agent storage hopper 5 and the port of the guide pipe 6, the agent in the agent storage hopper 5 will flow into the guide pipe 6 through the guide hole 9, and then be put into the wastewater in the treatment tank 1 through the guide pipe 6. Through the rotation of the rotating disk 8 and the design of the guide hole 9, the intermittent quantitative dosing of the agent is realized, which helps to ensure that the agent and the pollutants in the wastewater are fully contacted and reacted, thereby improving the treatment effect. At the same time, it avoids the phenomenon of waste caused by the agent not being fully utilized during the reaction process due to excessive dosing at one time.

[0025] A bracket 10 is fixed between the inner walls of both sides of the treatment tank 1. A second motor 11 is installed on the top side of the treatment tank 1. The output end of the second motor 11 is connected to a rotating rod 12, and the bottom end of the rotating rod 12 passes through the bracket 10. Multiple horizontal stirring rods 13 are fixed on the rotating rod 12, and multiple vertical stirring rods 14 are fixed on each horizontal stirring rod 13. A scraper 15 is fixed to the bottom end of the rotating rod 12, and the scraper 15 is in contact with the outer surface of the first filter screen 18. During operation, when treating sewage and intermittently adding chemicals, the second motor 11 operates, causing the rotating rod 12 to drive the horizontal stirring rods 13, vertical stirring rods 14, and scraper 15 to rotate. The rotation and stirring of the horizontal stirring rods 13 and vertical stirring rods 14 ensures the uniform distribution of chemicals in the sewage, allowing the chemicals to fully contact and react with the sewage, thus improving the treatment effect. The rotation of the scraper 15 can scrape off the deposits on the surface of the first filter screen 18, maintaining the permeability of the filter screen and avoiding clogging that affects the treatment efficiency.

[0026] Please see Figure 3 and Figure 6As shown, a first positioning slot 16 is provided on the inner wall of one side of the processing box 1, and a first through-hole 17 is provided on the other side of the processing box 1. A first filter screen 18 is inserted into the first positioning slot 16 and the first through-hole 17. A first push-pull plate 19 is fixed to one side of the first filter screen 18, and a first handle 20 is mounted on the first push-pull plate 19. When the device is in operation, the first filter screen 18 can be easily replaced by the cooperation of the first positioning slot 16 and the first through-hole 17. Regular replacement of the filter screen can prevent clogging and ensure the subsequent filtration effect.

[0027] A second positioning slot 21 is provided on the inner wall of one side of the filter box 2, and a second opening 22 is provided on the other side of the filter box 2. A second filter screen 23 is inserted into the second positioning slot 21 and the second opening 22. A second push-pull plate 24 is fixed to one side of the second filter screen 23, and a second handle 25 is mounted on the second push-pull plate 24. When using the device, the second filter screen 23 can be easily replaced by the cooperation of the second positioning slot 21 and the second opening 22. Regular replacement of the filter screen can prevent clogging and ensure the subsequent filtration effect.

[0028] Please see Figure 2-3 As shown, a pump body 26 is installed on the top side of the filter box 2. The inlet of the pump body 26 is connected to a water pumping pipe 27, and the other end of the water pumping pipe 27 is connected to the bottom of the treatment box 1. The outlet of the pump body 26 is connected to an outlet pipe 28, and the other end of the outlet pipe 28 is located inside the filter box 2. A drain pipe 29 is connected to the bottom of one side of the filter box 2. During operation, when treating sewage, the agent reacts with the suspended solids and colloids in the sewage to form larger flocs. The flocs settle onto the first filter screen 18 under gravity. Through the action of the first filter screen 18, impurities and flocs can be intercepted. The pump body 26 is started, so that the water after the first filtration is drawn out through the water pumping pipe 27 and flows into the filter box 2 through the outlet pipe 28. Through the action of the second filter screen 23, fine impurities in the water can be further intercepted, so that the purified water is discharged through the drain pipe 29. Through staged filtration, the sewage treatment effect is improved.

[0029] Working Principle: Existing wastewater treatment devices typically add chemicals to the wastewater all at once, rather than dispensing them intermittently and quantitatively. This results in uneven chemical concentrations in some areas and insufficient concentrations in others, hindering the effective treatment of pollutants and reducing the chance of proper contact and reaction. Furthermore, the single-dose dosing may lead to waste as some chemicals are not fully utilized during the reaction. Therefore, this integrated wastewater treatment device addresses these issues. In this device, chemicals are added to the wastewater. After entering the treatment tank 1 through the inlet pipe 3, the first motor 7 rotates the rotating disk 8, causing the guide hole 9 to rotate as well. When the guide hole 9 aligns with the port of the chemical storage hopper 5 and the port of the feed pipe 6, the chemicals in the storage hopper 5 will flow through... The flow from the guide hole 9 into the feed pipe 6 is then fed into the wastewater in the treatment tank 1 through the feed pipe 6. The rotation of the rotating disk 8 and the design of the guide hole 9 enable intermittent, quantitative dosing of the reagent. This helps ensure sufficient contact and reaction between the reagent and pollutants in the wastewater, improving treatment efficiency. Simultaneously, it avoids the waste caused by excessive dosing, which results in some reagent not being fully utilized during the reaction. During intermittent dosing, the second motor 11 is simultaneously activated, causing the rotating rod 12 to drive the horizontal stirring rod 13, vertical stirring rod 14, and scraper 15 to rotate. The rotation and stirring of the horizontal and vertical stirring rods 13 and 14 ensure uniform distribution of the reagent in the wastewater, allowing for sufficient contact and reaction between the reagent and the wastewater, thus improving treatment efficiency. The rotation of the scraper 15 removes deposits from the surface of the first filter screen 18, maintaining the screen's permeability and preventing clogging that could affect treatment efficiency.

[0030] During wastewater treatment, the chemicals react with suspended solids and colloids in the wastewater to form larger flocs. These flocs settle onto the first filter screen 18 under gravity. The first filter screen 18 intercepts impurities and flocs. The pump 26 is then activated, allowing the water after the initial filtration to be drawn out through the pumping pipe 27 and flow into the filter box 2 through the output pipe 28. The second filter screen 23 further intercepts fine impurities in the water, allowing the purified water to be discharged through the drain pipe 29. Through this staged filtration, the wastewater treatment effect is improved.
