Description

Technical Field

[0001] This invention relates to an automatic car wash system, and more specifically, to an automatic car wash system with a wastewater treatment tank. Background Technology

[0002] With the continuous development of society and economy, cars have become a common means of transportation for people to go out, and car washing has become a must for car owners. Most car owners choose to take their cars to car wash shops for cleaning. In recent years, with the continuous development and improvement of intelligent automation technology, self-service car wash equipment such as automatic car wash machines have appeared in many cities. This type of car washing is convenient, efficient and inexpensive, and is loved by the majority of car owners.

[0003] Currently, car wash wastewater discharge is achieved by digging underground drainage ditches and constructing three-stage sedimentation tanks. Two five-cubic-meter sedimentation tanks are dug underground, and wastewater is directly discharged into them. After the wastewater seeps into the ground, the sediment accumulates to a certain level, at which point it is manually dredged and removed. This drainage method, involving direct discharge, is highly wasteful of water resources and results in high car wash costs. Summary of the Invention

[0039] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments.

[0040] Example

[0041] Combination Figure 1 This embodiment of an automatic car wash system with a wastewater treatment tank includes a washing platform 1, a top frame 2, a car body washing assembly, and a wheel cleaning assembly. The top frame 2 is connected to the top plate of the washing platform 1 by four support columns. The front-to-back length of the washing platform 1 is greater than the front-to-back length of the top frame 2, and both the front and back ends of the washing platform 1 extend beyond the front and back ends of the top frame 2. This design ensures the collection of car wash wastewater. The car body washing assembly consists of two sets of first washing assemblies symmetrically arranged in the front-to-back direction and two sets of second washing assemblies symmetrically arranged in the left-to-right direction. The second washing assemblies are located between the left and right support columns and are connected by a second shear. The first scissor lift drive assembly is installed on the top frame, and the second scissor lift drive assembly can drive the second cleaning assembly to move up and down; the first cleaning assembly is connected to the drive end of the front and rear telescopic drive assembly 5 through the first scissor lift drive assembly 4, and the front and rear telescopic drive assembly 5 is installed on the top frame 2, wherein the telescopic direction of the front and rear telescopic drive assembly 5 is perpendicular to the lifting direction of the first scissor lift drive assembly 4, and the front and rear telescopic drive assembly 5 can drive the first scissor lift drive assembly 4 to move back and forth, and the first scissor lift drive assembly 4 can drive the first cleaning assembly to move up and down; the wheel cleaning assembly is movably set between the front and rear support columns through the first front and rear moving drive assembly 6.

[0042] Continuing and combining Figure 2 The top plate of the cleaning platform 1 has a first opening, and a water-retaining support plate 1-1 is provided at the first opening to support the vehicle in the front-to-back direction. The cleaning platform 1 has a sewage collection chamber 1-2 that communicates with the first opening. A drainage ditch 1-3 that runs through the sewage collection chamber in the front-to-back direction is formed in the middle of the bottom wall of the sewage collection chamber. Both ends of the drainage ditch 1-2 are connected to sewage treatment tanks 7. The clean water outlet pipe 7-1 of the sewage treatment tank 7 is connected to the first cleaning component, the second cleaning component, and the wheel cleaning component.

[0043] In this embodiment, when the vehicle drives onto the washing platform 1, the wheels are required to be supported on the drain support plate 1-1. Then, the vehicle body washing component is controlled to automatically wash the vehicle body, and the wheel cleaning component is controlled to automatically wash the wheels, thus achieving automatic car washing. The car wash wastewater is collected by the sewage collection chamber 1-2 and flows into the two sewage treatment tanks 7 through the drainage ditch 1-3 for sewage treatment. The treated water is then distributed to the first washing component, the second washing component, and the wheel cleaning component through the clean water outlet pipe 7-1, realizing water recycling and greatly saving water consumption.

[0044] Furthermore, in order to allow the water collected in the sewage collection chamber 1-2 to better converge towards the drainage ditch 1-3, the bottom of the sewage collection chamber 1-2 is designed with a V-shaped cross-section, so that the collected water can flow into the drainage ditch 1-3 better and faster along the inclined surface.

[0045] Continuing and combining Figure 3 The wastewater treatment tank includes a tank body 7-2, inside which a self-cleaning filter partition assembly is installed. The interior of the tank body 7-2 is divided into a left wastewater inlet chamber 7-4 and a right wastewater filter chamber 7-5 by the self-cleaning filter partition assembly, and the left wastewater inlet chamber 7-4 is connected to the right wastewater filter chamber 7-5 through the self-cleaning filter partition assembly. The left wastewater inlet chamber 7-4 is connected to a drainage ditch 1-3. A self-cleaning filter 10 with bottom inlet and top outlet is installed in the right wastewater filter chamber 7-5. The self-cleaning filter 10 is installed inside the tank body 7-2 through a filter mounting plate 7-3. The top of the self-cleaning filter 10 is connected to... A clean water outlet pipe 7-1 is connected; car wash wastewater enters the left sewage inlet chamber 7-4 through the drainage ditch 1-3, then undergoes the first filtration through the self-cleaning filter separator component before entering the right sewage filter chamber 7-5, and then undergoes the second filtration through the self-cleaning filter 10 before flowing out through the clean water outlet pipe 7-1. Both the self-cleaning filter separator component and the self-cleaning filter 10 have a self-cleaning function, which means that when the filtration effect is not good and cleaning is required, the self-cleaning filter separator component and the self-cleaning filter 10 can clean themselves automatically without the need for a person to enter the sewage treatment tank for cleaning.

[0046] Continuing and combining Figure 4The self-cleaning filter separator assembly includes a separator plate 7-6, a filter grid 7-7, and a grid cleaning assembly for cleaning the filter grid 7-7. The bottom end and the front and rear ends of the separator plate 7-6 are fixedly connected to the bottom wall and the front and rear side walls of the housing 7-2, respectively. A filter port is provided on the separator plate 7-6, and the filter grid 7-7 is disposed in the filter port. The filter grid 7-7 includes an upper baffle mounting roller, a lower baffle mounting roller, and multiple baffles tensioned and sleeved between the upper baffle mounting roller and the lower baffle mounting roller. The multiple baffles are arranged sequentially at intervals along the front and rear direction. The support shafts at the front and rear ends of the upper baffle mounting roller are rotatably supported on the top of two vertical mounting plates 7-8, respectively. The support shafts at the front and rear ends of the lower baffle mounting roller are rotatably supported on the bottom of two vertical mounting plates 7-8, respectively. The two vertical mounting plates 7-8 and the separator plate 7-6 are both arranged perpendicular to each other, and the two vertical mounting plates 7-8 are fixedly connected to the front and rear side walls of the filter port, respectively.

[0047] The grid cleaning assembly includes a first rotary drive 11-1 fixed to the top of the partition plate, a first roller brush 11-2 located in the left sewage inlet chamber 7-4, and a first water spray cleaning pipe 11-3. Multiple first nozzles are arranged on the side of the first water spray cleaning pipe 11-3 facing the filter grid 7-7. The front and rear ends of the first water spray cleaning pipe 11-3 are respectively supported on the tops of two vertical mounting plates 7-8. The first roller brush 11-2 is located below the first water spray cleaning pipe 11-3, and the support shafts at the front and rear ends of the first roller brush 11-2... Each is rotatably supported on the top of two vertical mounting plates 7-8; the first rotary driver 11-1 is connected to the upper baffle mounting roller and the first roller brush 11-2 respectively through the first transmission mechanism; the first transmission mechanism here is a belt drive mechanism, including a first driven wheel fixed on the support shaft at one end of the first roller brush 11-2, a first driving wheel fixed on the upper baffle mounting roller, and a first belt tensioned and sleeved outside the first driven wheel and the first driving wheel, wherein the driving wheel is fixedly connected to the driving end of the first rotary driver 11-1.

[0048] During filtration by the self-cleaning filter separator assembly, wastewater in the left wastewater inlet chamber 7-4 enters the right wastewater filter chamber 7-5 through the filter grid 7-7. Specifically, water passes through the gap between two adjacent baffles, while sludge and impurities are blocked by the baffles. When the self-cleaning filter separator assembly automatically cleans, the first rotary drive 11-1 is activated, which then drives the first roller brush 11-2 and the upper baffle mounting roller to rotate together via the first transmission mechanism. Here, the rotation of the first roller brush 11-2 cleans the baffles. The upper and lower baffle mounting rollers are connected by a baffle, and the rotation of the upper baffle mounting roller drives the rotation of the lower baffle mounting roller and the baffle. This, combined with the first roller brush 11-2, can clean the entire baffle. In addition, water in the first water spray cleaning pipe is sprayed out from the first nozzle onto the baffle, so that the first roller brush 11-2 can clean while water is sprayed, resulting in a more thorough cleaning. The water in the first water spray cleaning pipe can be water treated by the sewage treatment tank 7 or other clean water.

[0049] Continuing and combining Figure 5 The self-cleaning filter includes a housing 10-1, a filter element 10-2, and a filter element cleaning assembly for cleaning the filter element 10-2. The upper and lower ends of the housing 10-1 are respectively fixedly connected to an upper outlet pipe 10-3 and a lower inlet pipe 10-4, which communicate with the interior of the housing 10-1. The housing 10-1 is fixed to the filter mounting plate 7-3 via the upper outlet pipe 10-3. The top of the filter element 10-2 has an outlet pipe 10-5 communicating with the water outlet chamber inside the filter element 10-2, and the bottom of the filter element 10-2 has a rotating shaft 10-6 fixedly installed.

The water outlet pipe 10-5 and the clean water outlet pipe 7-1, as well as the water outlet pipe 10-5 and the upper outlet pipe 10-3, are rotatably and sealingly connected. The rotating shaft 10-6 at the bottom of the filter element 10-2 is rotatably supported on the filter element mounting plate 10-7. The filter element mounting plate 10-7 is fixed inside the outer shell 10-1 and has holes for connecting the water inlet chamber and the lower inlet pipe 10-4.

[0050] The filter element cleaning assembly includes a second rotary actuator 12-1, a first lead screw 12-2, and a cleaning housing 12-3 arranged along the length of the filter element 10-2. The cleaning housing 12-3 is fixed to one side of the housing 10-1 and communicates with the interior of the housing 10-1. A first nozzle seat 12-4 is provided inside the cleaning housing 12-3 and slides vertically therewith.

[0051] During filtration in a self-cleaning filter, the water to be filtered in the right wastewater filtration chamber enters the inlet chamber through the lower inlet pipe 10-4, then passes through the filter element 10-2 before entering the interior of the filter element 10-2 and finally flowing out through the outlet pipe 10-5. To allow the filter element 10-2 to rotate for automatic cleaning, the outlet pipe 10-5 at the top of the filter element 10-2 is rotatably and sealingly connected to the upper outlet pipe 10-3 at the top of the outer casing 10-1. The rotating shaft 10-6 at the bottom of the filter element 10-2 is rotatably supported on the filter element mounting plate 10-7. The holes in the filter element mounting plate 10-7 ensure that the water to be filtered can enter from the space below the filter element mounting plate 10-7 in the outer casing 10-1 and then enter the space above the filter element mounting plate 10-7 in the outer casing 10-1, thus smoothly passing through the filter element 10-2 for filtration. When the cleaning filter is automatically cleaned, the second rotary drive 12-1 is controlled to drive the first lead screw 12-2 to rotate. Since the first nozzle seat 12-4 is connected to the first lead screw 12-2 through the first ball nut, it can drive the first nozzle seat 12-4 to move up and down. In this way, the second nozzle on the first nozzle seat 12-4 can spray water onto the filter element 10-2 for cleaning. Since the first lead screw 12-2 is connected to the water outlet pipe 10-5 at the top of the filter element 10-2 through the second transmission mechanism, it can drive the water outlet pipe 10-5 to rotate, which in turn drives the filter element 10-2 to rotate. In this way, the second nozzle can clean the entire outer circumference of the filter element 10-2. In addition, the water sprayed by the second nozzle can be supplied by the water treated by the sewage treatment tank 7 or other clean water.

[0053] The bottom wall of the housing 7-2 has recessed drainage ditches 7-9 arranged in the front-to-back direction at both ends. Each drainage ditch 7-9 is equipped with an auger 14. One end of the auger 14 is connected to the fourth rotary drive 15, which is fixed on the side plate of the housing 7-2 near the cleaning platform 1. The other end of the auger 14 is directly opposite the drain outlet 7-10, which is located on the side plate of the housing 7-2 away from the cleaning platform 1.

[0054] When the bottom wall cleaning component performs automatic cleaning, the third rotary drive 13-1 is controlled to drive the bidirectional threaded screw 13-2 to rotate. Since both the positive thread section and the negative thread section are connected to the scraper 13-3 through the second ball nut, the two scrapers 13-3 can move in opposite directions to scrape off the sludge on the bottom wall of the box 7-2 and push it into the drainage ditch 7-9. Finally, the fourth rotary drive 15 is controlled to drive the auger 14 to rotate, and the auger 14 discharges the sludge and impurities in the drainage ditch 7-9 from the drain outlet 7-10.

[0055] Continuing and combining Figure 6 In order to collect the sludge and impurities discharged from the sewage outlet 7-10, an auxiliary box 7-11 is fixed on the outer side of the box 7-2 away from the cleaning platform 1. Sludge collection boxes 7-12 are set in the auxiliary box 7-11 corresponding to the two sewage outlets 7-10. The two sludge collection boxes 7-12 are driven up and down by a lifting linkage mechanism. When sludge needs to be collected, the lifting linkage mechanism controls the two sludge collection boxes 7-12 to descend below the sewage outlet 7-10, which facilitates the collection of sludge. When the sludge is collected and processed, the lifting linkage mechanism controls the two sludge collection boxes 7-12 to rise and extend out of the auxiliary box 7-11, which facilitates the cleaning personnel to remove the sludge.

[0056] The lifting linkage mechanism here includes two scissor-type lifting components 16-5 and a seventh rotary actuator 16-1.

[0061] The valve stem 17-9 includes a first sealing section, a first connecting section, a second sealing section, a second connecting section, and an abutment section for abutting against the wheel, connected in sequence. The diameter of the first connecting section is smaller than the diameter of both the first and second sealing sections. The second sealing section is slidably and sealingly connected to the through hole connecting the second cleaning outlet chamber 17-4-3 and the pawl mounting chamber 17-4-4. The two ends of the spring 17-10 sleeved on the second sealing section abut against the pawl mounting chamber 17-4-4. -4-4 The bottom of the cavity and the stepped surface on the second sealing section; wherein, when the first sealing section blocks the through hole connecting the first cleaning water outlet cavity 17-4-1 and the cleaning water inlet cavity 17-4-2, the cleaning water inlet cavity 17-4-2 and the second cleaning water outlet cavity 17-4-3 are connected; when the second sealing section blocks the through hole connecting the cleaning water inlet cavity 17-4-2 and the second cleaning water outlet cavity 17-4-3, the first cleaning water outlet cavity 17-4-1 and the cleaning water inlet cavity 17-4-2 are connected;

[0062] When the spring 17-10 is in its natural state, the first sealing section blocks the through hole connecting the first cleaning water outlet chamber 17-4-1 and the cleaning water inlet chamber 17-4-2, and the cleaning water inlet chamber 17-4-2 and the second cleaning water outlet chamber 17-4-3 are connected; when the spring 17-10 is in its compressed state, the first sealing section is located inside the first cleaning water outlet chamber 17-4-1, and the second sealing section blocks the through hole connecting the cleaning water inlet chamber 17-4-2 and the second cleaning water outlet chamber 17-4-3, and the first cleaning water outlet chamber 17-4-1 and the cleaning water inlet chamber 17-4-2 are connected.

[0063] A cross support frame 17-9-1 is fixed on the second connecting section and located in the pawl mounting cavity 17-4-4; four clearance notches 17-4-5 are provided on the open edge of the valve barrel 17-4 corresponding to the four ends of the cross support frame 17-9-1, which are arranged along the axial direction of the valve barrel 17-4; a pawl 17-11 is hinged in each clearance notch 17-4-5, one end of the pawl 17-11 is hinged to the end of the cross support frame 17-9-1 by a hinge shaft, and the hinge shaft is slidably engaged with the sliding groove hole 17-11-1 provided on the pawl 17-11 along the length direction of the pawl 17-11; the other end of the pawl 17-11 extends out of the pawl mounting cavity 17-4-4, and a fourth nozzle is provided on the side of the other end of the pawl 17-11 facing the valve stem 17-9;

[0065] When the wheel is being cleaned, when the spring 17-10 is in its natural state, the first sealing section seals the through hole connecting the first cleaning water outlet chamber 17-4-1 and the cleaning water inlet chamber 17-4-2. The cleaning water inlet chamber 17-4-2 and the second cleaning water outlet chamber 17-4-3 are connected, and the four pawls are in the unfolded state.

[0066] First, perform wheel hub cleaning: Control the scissor telescopic drive assembly 17-5 to work, so that the fourth nozzle on the four pawls faces the wheel hub directly, and at the same time, water is supplied to the cleaning inlet chamber 17-4-2. Since the second cleaning outlet chamber 17-4-3 is connected to the fourth nozzle through a water pipe, water can enter the fourth nozzle through the second cleaning outlet chamber 17-4-3, thereby enabling the fourth nozzle to spray water to clean the wheel hub.

[0067] Then, tire cleaning is performed: Continue controlling the scissor-type telescopic drive assembly 17-5, causing the driven section of the swing arm 17-7 to move upwards towards the wheel, and causing the valve stem 17-9 to abut against the center point of the wheel hub. At this time, the spring 17-10 is compressed, and the valve stem 17-9 slides away from the wheel. The sliding of the valve stem 17-9 drives the hinge shaft to move away from the wheel within the slide hole 17-11-1, causing the free end of the pawl 17-11 to rotate towards the valve stem 17-9. Continue controlling the scissor-type telescopic drive assembly 17-5 until the first sealing section seals the through hole connecting the first cleaning outlet chamber 17-4-1 and the cleaning inlet chamber 17-4-2, and the cleaning inlet chamber... When the first cleaning water outlet chamber 17-4-2 and the second cleaning water outlet chamber 17-4-3 are connected, the four pawls 17-11 retract, and the driven section of the swing arm 17-7 extends above the wheel. Since the first cleaning water outlet chamber 17-4-1 and the second water spray cleaning pipe 17-3 are connected by a water pipe, the third nozzle on the second water spray cleaning pipe 17-3 can spray water to clean the tire. Since the swing drive component can drive the swing arm 17-7 to swing, it can swing back and forth to clean the tire. The water pressure is large and the cleaning effect is good. The tire cleaning and wheel hub cleaning share a cleaning water supply system, and the water pressure is concentrated first for wheel hub cleaning and then for tire cleaning, resulting in a good cleaning effect.

[0068] Further, see Figure 2 To clean the wheel rims, a wheel rim cleaning assembly is installed inside the sewage collection chamber 1-2 and below each leaking support plate 1-1.
