Furthermore, it can be controlled intelligently without human intervention and boasts advantages such as small size, portability, and easy installation.

[0003] Although the aforementioned patent allows for the recycling of wastewater, car wash wastewater contains a large amount of impurities such as mud, oil, and detergent. During the filtration process, these impurities gradually adhere to the surface of the filter media, causing the filter media pores to become smaller or even clogged. If backwashing is not possible, these clogged filter media cannot be cleaned, the filtration efficiency will gradually decrease, and eventually the equipment will not work properly. Therefore, it is necessary to design a car wash wastewater recycling and purification device to solve the above problems. Utility Model Content

Detailed Implementation

[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 protection scope of the present utility model.

[0024] Example

[0025] like Figure 1-5 As shown, a car wash wastewater circulation and purification device includes a conveying pipe 1, a water pump 2 fixedly connected to one side of the outer surface of the conveying pipe 1, an inlet pipe 3 fixedly connected to one side of the upper surface of the conveying pipe 1, a wastewater inlet valve 4 fixedly connected to one side of the outer surface of the inlet pipe 3, a purification tank 5 fixedly connected to one end of the inlet pipe 3, an outlet pipe 6 fixedly connected to the middle of the lower surface of the purification tank 5, the outlet pipe 6 being fixedly connected to the conveying pipe 1, a purification water pipe 7 fixedly connected to the top of the outer surface of the outlet pipe 6, a purification water outlet valve 8 fixedly connected to one side of the outer surface of the purification water pipe 7, a connecting pipe 9 fixedly connected to the outer surface of the inlet pipe 3 near the wastewater inlet valve 4, the connecting pipe 9 being fixedly connected to the conveying pipe 1, a backwash outlet valve 10 fixedly connected to the outer surface of the connecting pipe 9, a backwash inlet valve 11 fixedly connected to the outer surface of the conveying pipe 1 near the inlet pipe 3, and a forward wash outlet valve 12 fixedly connected to the outer surface of the conveying pipe 1 near the backwash inlet valve 11.

[0026] In practical use, the wastewater from car washes enters the coagulation pipe via a wastewater pump through the conveying pipe 1, inlet pipe 3, outlet pipe 6, and connecting pipe 9. By adding flocculant, suspended solids in the water react with the flocculant to form flocs. The raw water, after flocculant addition, flows into a sedimentation tank for settling. The settled water undergoes wastewater purification treatment. The conveying pipe 1, through pump 2 and inlet pipe 3, introduces the wastewater from the sedimentation tank into the purification tank 5, and then delivers the purified water to the outlet pipe 6. Finally, it is discharged from the purified water pipe 7 to a designated location, allowing for the recycling of wastewater and preventing water waste. Pump 2 provides power for wastewater transport, ensuring smooth flow within the equipment and facilitating the entire purification process. The wastewater inlet valve 4 effectively controls the inflow rate and duration of the wastewater, allowing for flexible adjustment according to actual needs. The system allows for flexible adjustment to prevent excessive or insufficient wastewater flow from affecting the purification effect. The purified water pipe 7 transports the purified water to the usage location or other necessary locations. The purified water outlet valve 8 controls the outflow of purified water, allowing users to operate according to actual needs, such as pausing or adjusting the water flow. Before operation, backwashing is required. During backwashing, open the backwash inlet valve 11 and backwash outlet valve 10, while closing other valves. Then, backwash using a stainless steel backwash pump, flushing the water through the showerhead 15 and filter media directly into the wastewater equalization tank for treatment and reuse. Backwashing generally continues until the water is clear. After backwashing, forward washing is required. During forward washing, open the wastewater inlet valve 4 and forward wash outlet valve 12, and start the delivery pump to flush until the outlet is clear. This effectively removes impurities and blockages from the filter media surface, restores the filter media's filtration performance, and extends the equipment's service life.

[0027] In this embodiment, a first pressure gauge 13 is fixedly connected to one side of the outer surface of the water inlet pipe 3, and a second pressure gauge 14 is fixedly connected to one end of the water outlet pipe 6.

[0028] In practical use, the first pressure gauge 13 and the second pressure gauge 14 are installed on the inlet pipe 3 and the outlet pipe 6, respectively, to monitor the pressure of the inlet and outlet water in real time. By observing the readings of the pressure gauges, the operator can understand the operating status of the equipment in a timely manner and determine whether there is pipe blockage, filter media blockage or other abnormalities. For example, if the inlet water pressure is too high and the outlet water pressure is too low, it may mean that the filter media is seriously blocked and backwashing or replacement of the filter media is required in time.

[0029] In this embodiment, the purification tank 5 includes a tank body 501 fixed to one end of the water outlet pipe 6, and a top cover 502 is fixedly connected to the upper surface of the tank body 501 by connecting flanges and bolts.

[0030] In practical use, the tank body 501 is used to hold filter media and sewage. The top cover 502 is fixedly connected to the tank body 501 by connecting flanges and bolts. This connection method is not only firm and reliable, but also easy to disassemble and install. When it is necessary to maintain, replace filter media or inspect the inside of the purification tank 5, the top cover 502 can be easily opened to facilitate the operation of the operator.

[0031] In this embodiment, a sealing groove 503 is provided at the connection between the inner sides of the tank body 501 and the top cover 502, and a sealing ring 504 is movably connected inside the sealing groove 503.

[0032] In practical use, a sealing groove 503 is opened at the connection between the tank body 501 and the top cover 502, and a sealing ring 504 is installed in it, which can effectively prevent sewage from leaking from the connection and ensure the sealing performance of the equipment.

[0033] In this embodiment, a support column 505 is fixedly connected to the lower surface of the tank 501, and a fixing plate 506 is fixedly connected to the bottom of the outer surface of the support column 505.

[0034] In practical use, the support column 505 is fixed to the lower surface of the tank body 501 to support the entire purification tank 5 and keep it stable. The fixing plate 506 further enhances the stability of the support column 505, ensuring that the purification tank 5 will not shake or tilt during operation, so that the equipment can operate stably in various environments.

[0035] In this embodiment, a shower head 15 is fixedly connected to the inner bottom wall of the tank 501, and the shower head 15 is fixedly connected to the water outlet pipe 6. A bracket 16 is fixedly connected to the bottom of the inner side of the tank 501.

[0036] In practical use, the shower head 15 is installed on the inner bottom wall of the tank 501. During the purification process, the purified water is transported to the outside through the water outlet pipe 6. At the same time, during backwashing, the backwash water can be evenly distributed to the filter media to ensure the backwashing effect. The bracket 16 is used to support the net bag 17, providing a stable placement position for the filter media and ensuring that the filter media can be evenly distributed inside the tank 501 to give full play to the filtration function.

[0037] In this embodiment, a net bag 17 is movably connected to the upper surface of the support 16. The net bag 17 is provided in three sets, and the interior of the three sets of net bags 17 is filled with small quartz sand, activated carbon and ceramic filter material from the bottom to the top of the tank 501.

[0038] In practical use, the three sets of mesh bags 17 are filled with small quartz sand, activated carbon, and ceramsite filter media respectively. These filter media are placed in layers from the bottom to the top of the tank 501. Small quartz sand is mainly used to filter particulate impurities, such as silt, etc. Activated carbon has good adsorption performance and can effectively remove odors, pigments and some organic matter in sewage. Ceramsite filter media has a large specific surface area and porosity, which can further adsorb and filter fine particles and impurities in sewage. The layered filtration structure can deeply purify sewage and improve the purification effect. The modular design of the filter media is easy to install and replace, making the filling and installation of the filter media more convenient and greatly shortening the installation time and cost of the equipment.

[0039] In this embodiment, a stainless steel mesh 18 is movably connected to the top of the inner side of the tank 501, and a connecting rod 19 is fixedly connected to the bottom of the inner side of the top cover 502. One end of the connecting rod 19 is fixedly connected to a pressure block 20, and the pressure block 20 is movably connected to the stainless steel mesh 18.

[0040] In practical use, the stainless steel mesh 18 is installed on the top of the inner side of the tank 501 to prevent the filter material from being washed away by the water flow and to ensure that the filter material can remain stably inside the tank 501. The connecting rod 19 and the pressure block 20 further enhance the stability of the stainless steel mesh 18, so that it can be firmly fixed inside the tank 501, ensuring the normal operation of the equipment and the stability of the purification effect.

[0041] Working Principle: During use, backwashing is required before or after the equipment has been running for a period of time. At this time, open the backwash inlet valve 11 and the backwash outlet valve 10, while closing other valves. Then, start the stainless steel backwash pump. The backwash water flows through the backwash inlet valve 11 into the purification tank 5, passing through the showerhead 15, the filter media layer, and the stainless steel mesh 18, flushing away impurities and blockages on the surface of the filter media. Finally, the water is discharged from the equipment through the backwash outlet valve 10. The backwashing process effectively restores the filtration performance of the filter media, ensuring the normal operation of the equipment. After backwashing, open the wastewater inlet valve 4 and the forward wash outlet valve 10. Water valve 12, once the delivery pump is turned on, will flush until the outlet is clear. During normal operation, the car wash wastewater enters the coagulation pipe through the wastewater delivery pump. By adding flocculant, the suspended solids in the water and the flocculant react fully to form flocs. After the raw water is treated with flocculant, it flows into the sedimentation tank for sedimentation. The water after sedimentation is then treated for wastewater purification. The delivery pipe 1 introduces the wastewater from the sedimentation tank into the purification tank 5 through the water pump 2 and the inlet pipe 3, and then delivers the purified water to the outlet pipe 6. Finally, it is discharged from the purified water pipe 7 to the designated location, realizing the recycling of wastewater.
