Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a device for reusing wastewater from construction site car wash troughs. Background Technology

[0002] With the continuous development of my country's infrastructure, more and more large-scale construction projects are settling in urban areas. Construction sites generate a lot of dust and mud, and construction vehicles often carry a lot of mud with them when they leave the site. These construction vehicles seriously affect the cleanliness of urban roads when they drive in the city. Therefore, in cities, it is required that vehicles entering and leaving construction sites must be cleaned, and it is strictly forbidden for vehicles with mud on their tires and exteriors to be driven on the road. The site layout must also be neat and there should be no obvious dust and mud. Therefore, construction sites will set up car wash troughs to wash vehicles entering and leaving the site. However, the wastewater from car washes contains a lot of impurities such as mud, sand and gravel, and most of it is discharged directly without effective recycling. This results in a high consumption of fresh tap water, which increases the water cost of construction sites and does not meet the current industry requirements for green construction and water conservation.

[0020] Example 1 See Figures 1 to 6 This utility model provides a wastewater reuse device for construction site car wash troughs. The device consists of a base 1 embedded in the ground, a water collection trough 2 on the base 1, a support platform 3 for washing vehicles above the water collection trough 2, side frames 4 on both sides of the support platform 3, and several nozzles on each side frame 4. The nozzles 13 are connected to a water source through a water pipe, and a cleaning pump is also installed on the water pipe. The lower surface of the water collection tank 2 is inclined, and a drain pipe 5 is installed at the lowest point of the lower surface of the water collection tank 2. A water tank 6 is provided on one side of the base 1, and a filter mechanism 7 is provided on the upper part of the water tank 6; The filtration mechanism 7 includes a filter barrel 8 rotatably mounted on the upper part of the water tank 6. The filter barrel 8 is a hollow frustum shape, and several filter holes are provided on the side wall of the filter barrel 8. The large end of the filter barrel 8 is an open end, which extends to the outside of the water tank 6 and is rotatably connected to the water tank 6. The small end has a through hole, through which the filter barrel 8 is rotatably connected to the drain pipe 5.

[0021] When the vehicle drives to the support platform 3 directly above the water collection tank 2 on the base 1, the nozzle 13 sprays cleaning water onto the vehicle body and wheels to wash away the mud and dust carried by the vehicle. The car wash wastewater generated by washing flows from the gap of the support platform 3 into the water collection tank 2 below due to gravity. Because the lower surface of the water collection tank 2 is inclined, the wastewater will automatically gather at the lowest point of the lower surface along the inclined surface and flow to the filter mechanism 7 through the drain pipe 5 at this point. The drain pipe 5 transports wastewater to the filter bucket 8. The wastewater flows along the inner wall of the filter bucket 8 towards the large end. During this process, impurities such as mud, sand and gravel in the wastewater are intercepted by the filter holes on the side wall of the filter bucket 8. The filtered clean water seeps into the water tank 6 through the filter holes for storage. The intercepted impurities continue to move towards the large end of the filter bucket 8 due to the inertia of the wastewater flow. Finally, they are discharged directly to the outside of the water tank 6 from the large end opening that extends to the outside of the water tank 6, achieving complete separation of impurities and clean water. The filtered clean water stored in the water tank 6 can be pumped back to the nozzle 13 by the cleaning water pump for subsequent vehicle cleaning, thus realizing the recycling of wastewater. Furthermore, a cleaning water pump is installed on one side of water tank 6. This cleaning water pump is connected to the side frame nozzles. It pressurizes and delivers the filtered clean water in the water tank to the side frame nozzles. At the same time, a liquid level linkage switch is added to the water pipe. When the water level in the water tank is higher than the set threshold (e.g., 20cm), the switch is automatically turned on, and the cleaning water pump can directly draw circulating water for the nozzles. If the water level is lower than the threshold, the switch will be linked to open the tap water supply pipeline to replenish clean water to the nozzles, ensuring that the vehicle cleaning operation is continuous and uninterrupted. This prioritizes the use of circulating water to save water and avoids affecting the efficiency of vehicles entering and leaving the construction site due to water shortage in the water tank.

[0022] When the impurities trapped in the filter barrel 8 accumulate to a certain amount, the structure of the filter barrel 8 extending to the outside of the water tank 6 can be used to empty and clean the impurities left in the barrel by rotating the large end of the filter barrel 8 or opening the large end opening. After cleaning, the large end opening can be closed and the device can continue to be used.

[0023] The drain pipe 5 has an elbow at one end inside the filter barrel 8. An impeller 9 is also fixedly installed inside the filter barrel 8, and the impeller 9 is fixedly installed at the lower end of the filter barrel 8.

[0024] After the wastewater transported by the drain pipe 5 enters the filter barrel 8, because the drain pipe 5 is located at one end inside the filter barrel 8 with an elbow, the wastewater is guided by the elbow and the sprayed wastewater directly impacts the impeller 9 fixed inside the filter barrel 8. Under the action of the water flow impact force, the impeller 9 drives the filter barrel 8, which is fixedly connected to it, to rotate as a whole. The filter barrel 8 is driven to rotate directly by the kinetic energy of the wastewater itself, without the need for additional power devices such as motors and water pumps. This reduces the power consumption of the device, simplifies the structural complexity, and lowers the manufacturing and maintenance costs of the equipment, thus meeting the energy-saving and consumption-reducing needs of construction sites.

[0025] A rinsing unit 10 is also provided inside the water tank 6. The rinsing unit 10 includes a rinsing water pump 11 fixedly installed inside the water tank 6. The inlet of the rinsing water pump 11 extends to the bottom of the water tank 6, and the outlet extends to the top of the filter bucket 8 through the rinsing pipe 12. Several nozzles 13 are provided on the rinsing pipe 12 above the filter bucket 8, and the water outlet of the nozzles 13 faces the filter bucket 8.

[0026] When the filter barrel 8 is used for a certain period of time and the filter holes become clogged due to residual fine impurities, the flushing water pump 11 in the water tank 6 is started. The flushing water pump 11 draws clean water from the bottom of the water tank 6 and delivers it to the nozzle 13 above the filter barrel 8 through the flushing pipe 12. The nozzle 13 sprays high-pressure water towards the side wall of the filter barrel 8 to perform reverse flushing of the filter holes, washing away the fine mud, sand and debris and other impurities attached to the inside of the filter holes. The impurities that are washed away flow in the filter bucket 8 with the flushing water, and eventually, together with the original impurities, are discharged from the large end opening to the outside of the water tank 6, thus completing the cleaning of the filter holes.

[0027] The high-pressure water flow of the flushing unit 10 can actively remove the fine impurities remaining in the filter holes, preventing the filtration speed from decreasing due to blockage after long-term use, keeping the filtration efficiency stable, and ensuring that the water tank 6 can continuously collect enough clean water for circulation. There is no need to frequently disassemble the filter canister 8 for manual cleaning. The filter holes can be cleaned by the rinsing unit 10, which reduces mechanical wear on the filter canister 8 and extends its service life.

[0028] A protective shell 14 is provided on the upper part of the water tank 6, and the protective shell 14 is fitted on the outside of the filter barrel 8.

[0029] When the filter bucket 8 rotates, the wastewater inside the bucket is easily thrown out of the filter holes by centrifugal force. The protective shell 14 is fitted on the outside of the filter bucket 8, which can firmly intercept the thrown wastewater inside the shell and let it fall back into the water tank 6 along the inner wall of the protective shell 14, so that it can participate in subsequent recycling instead of being directly lost to the ground and wasted.

[0030] A slot is provided at the lower part of the protective shell 14, and a filter element 15 is detachably installed in the slot. The filter element 15 is located below the filter barrel 8.

[0031] Filter element 15 includes a frame detachably connected to the slot, on which filter media is provided. The filter media is preferably stainless steel wire mesh, which is inexpensive and can be repeatedly washed and used. It can be rinsed with a high-pressure water gun, has a long service life, and reduces the frequency of replacement. Although most impurities have been removed from the water filtered by the filter canister 8, a small amount of fine silt or suspended matter may remain. The filter element 15 at the bottom of the protective shell 14 is located directly below the filter canister 8 and can perform secondary interception and filtration of the water seeping from the filter holes of the filter canister 8, further adsorbing or blocking fine impurities. The filter element 15 can be detached and installed through the slot at the bottom of the protective shell 14. After the filter element 15 has been used for a period of time, there is no need to disassemble the protective shell 14 or the filter canister 8. You can simply take out the old filter element 15 directly from the slot and replace it with a new filter element 15 to complete the maintenance. The operation is convenient and quick, greatly reducing the maintenance time.

[0032] When this utility model is in use, the vehicle drives to the support platform 3 directly above the water collection tank 2 on the base 1. At this time, the nozzle sprays cleaning water onto the vehicle body and wheels to wash away the mud, sand and dust carried by the vehicle. The car wash wastewater generated by washing flows from the gap of the support platform 3 into the water collection tank 2 below due to gravity. Because the lower surface of the water collection tank 2 is inclined, the wastewater will automatically gather at the lowest point of the lower surface along the inclined surface and flow to the filter mechanism 7 through the drain pipe 5 at this point. The drain pipe 5 transports wastewater to the filter bucket 8. The wastewater flows along the inner wall of the filter bucket 8 towards the larger end. During this process, impurities such as mud, sand, and gravel in the wastewater are intercepted by the filter holes on the side wall of the filter bucket 8. The filtered clean water seeps into the water tank 6 through the filter holes for storage. The intercepted impurities continue to move towards the larger end of the filter bucket 8 due to the inertia of the wastewater flow, and are finally discharged directly to the outside of the water tank 6 from the larger end opening that extends to the outside of the water tank 6, thus achieving complete separation of impurities and clean water.
