Description

Technical Field

[0001] This utility model relates to the field of water circulation technology, specifically to a circulating and purifying device for car wash water. Background Technology

[0002] Car wash water is water specifically used for vehicle cleaning. It must meet requirements such as strong cleaning power, non-corrosiveness, and environmental friendliness. High-quality car wash water often contains active cleaning ingredients that can quickly break down oil stains and mud. At the same time, water wax is added, leaving the car body shiny and new after washing. It can also form a protective film, reduce dust adhesion, and extend the life of the car paint.

[0003] Using a circulating purification device allows car wash water to be reused after undergoing a series of treatment processes such as sedimentation, filtration, and disinfection. This significantly reduces the water consumption per car wash, effectively alleviating the pressure on water resources. Therefore, a circulating purification device is necessary. However, traditional car wash water circulating purification devices are not convenient for disassembling and replacing the filter purification material. If the material cannot be disassembled and replaced in a timely manner, its adsorption performance will be greatly weakened, making it difficult to fully remove impurities from the wastewater. This results in excessive levels of soluble pollutants in the circulating water, deterioration of the effluent water quality, and the car wash water may also exhibit odors, acidification, and other phenomena. Utility Model Content

[0004] The purpose of this invention is to provide a circulating purification device for car wash water to solve the problems mentioned in the background art.

[0015] 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.

[0016] Please see Figure 1-5 As shown, a car wash water recycling and purification device includes a wastewater tank 1 and a recycled water tank 3. A sludge tank 2 is fixed between the wastewater tank 1 and the recycled water tank 3. A support assembly 4 is installed on the top of the sludge tank 2, and a purification box 5 is installed on the top of the support assembly 4. The wastewater tank 1 stores the wastewater generated from car washing. The wastewater flows into the wastewater tank 1 for temporary storage after car washing, providing a source of water to be purified for subsequent treatment. The sludge tank 2 is used to collect the sludge generated during the wastewater purification process. The sludge generated after the car wash wastewater is treated will settle into the sludge tank 2. Regular cleaning can prevent sludge accumulation from affecting the entire process. When the device is in operation, the sludge is discharged through the valve at the bottom of the sludge tank 2. The recycled water tank 3 can store the purified water for car washing again. When the purified water flows into the recycled water tank 3 through the water suction component 16 and other structures, water can be directly drawn from the recycled water tank 3 during car washing operations to achieve water resource recycling. The purification tank 5, as the core place for sewage purification, can accommodate the filter component 6 and other materials to carry out physical and chemical purification treatment of sewage. After the sewage pump 8 pumps the sewage from the sewage tank 1 to the purification tank 5, the purification tank 5 uses the internal filter component 6 and flocculants and other substances to purify the sewage.

[0017] The filter assembly 6 is located inside the purification tank 5. The filter assembly 6 includes a stainless steel mesh 61 installed inside the purification tank 5. A ceramic granule filter media layer 62 is fixed to the bottom of the stainless steel mesh 61. An activated carbon layer 63 is fixed to the bottom of the ceramic granule filter media layer 62. A quartz sand layer 64 is fixed to the bottom of the activated carbon layer 63. In the filter assembly 6, the stainless steel mesh 61 can intercept large particulate impurities. The ceramic granule filter media layer 62 can further filter smaller suspended impurities and some organic matter in the water, while also playing a certain role in biodegradation. The activated carbon layer 63 removes odors, pigments and residual small molecule organic matter in the water through adsorption. The quartz sand layer 64 can filter fine impurities and improve water clarity. When sewage enters the purification tank 5, it will pass through the stainless steel mesh 61, the ceramic granule filter media layer 62, the activated carbon layer 63 and the quartz sand layer 64 in sequence to complete multi-stage filtration and purification. Finally, it is extracted by the water absorption assembly 16 and the shower head 17.

[0018] The disassembly assembly 7 is located above the filter assembly 6. The disassembly assembly 7 includes multiple sets of magnetic plates 71 fixed to the top of the stainless steel mesh 61. The inner wall of the purification box 5 is fixed with an iron plate 72 for magnetic connection with the magnetic plates 71. The disassembly assembly 7 consists of magnetic plates 71 and iron plates 72. Through magnetic connection, it is convenient to disassemble and replace the filter assembly 6. When the filter media of the filter assembly 6 needs to be replaced and maintained, the magnetic force between the magnetic plates 71 and iron plates 72 can be overcome by external force to remove the filter assembly 6 from the purification box 5. After maintenance, the filter assembly 6 is put back, so that the magnetic plates 71 and iron plates 72 automatically attract and fix it. It should be noted that the magnetic plates 71 are made of neodymium iron boron strong magnetic material and are coated with an anti-rust coating to avoid long-term contact with water and magnetic attenuation. At the same time, the surface of the iron plate 72 is also coated with an anti-rust coating and sprayed with epoxy resin or polyurethane paint with a thickness of ≥50μm to isolate water from metal contact.

[0019] The support assembly 4 includes a support base 41 fixed to the top of the sludge tank 2. Multiple sets of support columns 42 are fixed to the top of the support base 41, and one end of the support column 42 is fixedly connected to the bottom of the purification box 5. The support assembly 4 is composed of the support base 41 and the support column 42, which can provide a stable support for the purification box 5. The support base 41 is fixed to the top of the sludge tank 2, and the support column 42 lifts the bottom of the purification box 5, ensuring that the purification box 5 is stably positioned above the sludge tank 2, which facilitates the connection of other structural components.

[0020] The sewage tank 1 is equipped with a sewage pump 8. The outlet of the sewage pump 8 is connected to an installation pipe 9, and one end of the installation pipe 9 is connected to the inner wall of the purification tank 5. The sewage pump 8 can pump sewage out of the sewage tank 1 and transport it to the purification tank 5 through the installation pipe 9, providing power support for the sewage to enter the purification process and ensuring that the sewage can continuously flow from the sewage tank 1 to the purification tank 5 for purification treatment. The installation pipe 9 is the transmission channel for sewage from the sewage pump 8 to the purification tank 5, guiding the sewage pumped by the sewage pump 8 to smoothly enter the interior of the purification tank 5.

[0021] A flocculant tank 10 is fixed to the top of the sludge tank 2. A connecting pipe 11 is installed inside the flocculant tank 10, with one end of the connecting pipe 11 connected to a dosing pump 12. The flocculant tank 10 stores flocculant, which, under the action of the dosing pump 12, can be quantitatively added to the wastewater in the installation pipe 9 through the connecting pipe 11 and connecting pipe 13. This creates conditions for the flocculation and sedimentation of suspended particles and other impurities in the wastewater. The connecting pipe 11 connects the flocculant tank 10 to the dosing pump 12, allowing the flocculant in the flocculant tank 10 to... The flocculant can flow into the metering pump 12, which facilitates the extraction and delivery of the flocculant. The metering pump 12 can control the amount of flocculant added according to the amount of sewage and pump the flocculant from the flocculant tank 10 to the connecting pipe 13 to ensure that an appropriate amount of flocculant is mixed with the sewage, so that the suspended impurities in the sewage can be effectively flocculated and precipitated. When the metering pump 12 is turned on, the flocculant inside the flocculant tank 10 is extracted by the connecting pipe 11, delivered through the connecting pipe 13 to the installation pipe 9, and finally delivered to the purification tank 5.

[0022] The discharge end of the dosing metering pump 12 is connected to a connecting pipe 13, and one end of the connecting pipe 13 is connected to the inner wall of the installation pipe 9. The connecting pipe 13 is used to introduce the flocculant output by the dosing metering pump 12 into the installation pipe 9, so that the flocculant and the sewage pumped by the sewage pump 8 can be mixed in the installation pipe 9, providing a place for flocculation reaction.

[0023] Multiple sets of baffles 14 are fixed to the inner wall of the purification tank 5, and the baffles 14 are arranged vertically. A bracket 15 is fixed to the top of the reclaimed water tank 3, and a water suction component 16 is fixed to the top of the bracket 15. The baffles 14 prolong the residence time of sewage in the purification tank 5, allowing the sewage and flocculant to react fully, and promoting better sedimentation of flocculants. After the sewage enters the purification tank 5, it will flow in a circuitous manner under the obstruction and guidance of the baffles 14, thereby increasing the contact reaction time with the flocculant and the opportunity for flocculant sedimentation. The bracket 15 can support the water suction component 16 and the backwash component 18. The water suction assembly 16 and the backwash assembly 18 are fixed in a suitable position below the purification tank 5 to ensure their smooth operation. The water suction assembly 16 is used to draw water purified by the filter assembly 6 from the purification tank 5 and then transport it to the recycled water tank 3 to complete the collection and transfer of purified water. The purified water flows into the recycled water tank 3 for storage and later use. It is noted that the water suction assembly 16 consists of a water pump and two fixed pipes, and one end of the fixed pipe is connected to the inner wall of the shower head 17. When the water pump is turned on, clean water enters from the shower head 17, passes through the two fixed pipes, and finally flows to the recycled water tank 3.

[0024] Multiple showerheads 17 are provided on one side of the water absorption assembly 16, and the showerheads 17 are located below the filter assembly 6. A backwash assembly 18 for cleaning the filter assembly 6 is provided on the top of the bracket 15. The showerheads 17 are distributed on one side of the water absorption assembly 16 and below the filter assembly 6, so as to evenly receive the purified water absorbed by the water absorption assembly 16 and prevent the water flow from being too concentrated and impacting the recycled water tank 3. It should be noted that the showerheads 17 are connected to the fixed pipe in the water absorption assembly 16 for cleaning the purified water. The backwash assembly 18 consists of a backwash pump and two connecting pipes. The backwash pump is fixed to the top of the bracket 15. One set of connecting pipes connects to the inner wall of the purification tank 5 and is located at the bottom of the filter assembly 6. The other connecting pipe extends into the reclaimed water tank 3. During use, to maintain the cleanliness of the filter material, a backwash can be performed. The backwash pump uses clean water from the reclaimed water tank 3 to pressure flush the showerhead 17, quartz sand layer 64, activated carbon layer 63, and ceramsite filter media layer 62. It is explained here that... Figure 2 As shown, the L-shaped pipe on the outside of the installation pipe 9 is a return pipe. One end is connected to the purification box 5, and the other end is connected to the sewage tank 1. It is used to return the impurities of the filter material to the sewage tank 1. Because the backwash water flow direction is opposite to the normal filter water flow direction, it washes off the impurities attached to the filter material. Then, with the help of the water flow, the impurities can enter the return pipe.

[0025] Working principle: First, the wastewater from the car wash flows into the wastewater tank 1. The flocculant tank 10 at the top of the sludge tank 2 stores flocculant. After the dosing metering pump 12 is turned on, the flocculant in the flocculant tank 10 is extracted through the connecting pipe 11 and transported to the installation pipe 9 through the connecting pipe 13. At this time, the wastewater pump 8 also starts working, extracting the wastewater from the wastewater tank 1 and transporting it to the purification tank 5 through the installation pipe 9. In the installation pipe 9, the flocculant and wastewater are fully mixed. Under the action of the flocculant, suspended particles, colloids and other impurities in the wastewater are agglomerated into larger flocs, creating favorable conditions for subsequent filtration and separation. The wastewater containing flocculants enters the purification tank 5. In the purification tank 5, multiple sets of vertically arranged baffles 14 change the flow path of the wastewater, making it meandering. The flow of water not only prolongs the residence time of wastewater in the purification tank 5, but also allows for a more complete reaction between the wastewater and the flocculant, promoting better sedimentation of the flocculants. Simultaneously, the wastewater undergoes multi-stage filtration through the filter assembly 6. First, the stainless steel mesh 61 intercepts large particles of impurities in the wastewater. Next, the ceramic granule filter media layer 62 further filters smaller suspended impurities and degrades some organic matter. Subsequently, the activated carbon layer 63 uses adsorption to remove odors, pigments, and residual small-molecule organic matter from the water. Finally, the quartz sand layer 64 filters fine impurities, improving water clarity. After this series of treatments, the wastewater is effectively purified. The purified water reaches below the filter assembly 6 and is received by the showerheads 17 located there. The showerheads 17 and the fixed... With the pipes connected, the water pump of the water suction component 16 is activated, pumping purified water through two fixed pipes to the recycled water tank 3 for storage. During car washing operations, water can be directly drawn from the recycled water tank 3, realizing the recycling of water resources. The sludge generated during the sewage purification process settles to the bottom of the sludge tank 2. The valve at the bottom of the sludge tank 2 is opened periodically to discharge the sludge and clean it, preventing sludge accumulation from affecting the normal operation of the entire device. When it is necessary to replace the filter media in the filter component 6, the magnetic force between the magnetic plate 71 and the iron plate 72 is overcome by external force. At this time, the filter component 6 can be removed from the purification box 5 for maintenance. After maintenance, the filter component 6 is put back into the purification box 5, and the magnetic plate 71 and the iron plate 72 automatically adhere and fix it, ensuring the normal operation of the filter component 6 and maintaining the purification device. To ensure efficient operation, when the filter assembly 6 needs cleaning, the backwash pump is started to extract clean water from the recycled water tank 3. One connecting pipe extends from the recycled water tank 3 to introduce clean water, while the other connecting pipe is connected to the inner wall of the purification tank 5 and located at the bottom of the filter assembly 6. Under the pressure of the backwash pump, the clean water passes through the shower head 17 and flows in reverse through the quartz sand layer 64, the activated carbon layer 63, and the ceramic granule filter media layer 62, performing pressure rinsing on the filter materials. During the rinsing process, impurities on the filter assembly 6 are transported to the return pipe with the water flow. Since the return pipe is connected to the sewage tank 1, the impurities are finally discharged into the sewage tank 1, thus completing the cleaning of the filter assembly 6, restoring its filtration performance, and ensuring the continuous and stable operation of the entire purification process.
