Description

Technical Field

[0001] This utility model relates to the technical field of car wash wastewater treatment, and in particular to an energy-saving car wash wastewater sand filtration purification and reuse device. Background Technology

[0002] Car washing uses a lot of water, resulting in a significant waste of water resources. Therefore, many car washes use technologies such as the car wash wastewater reuse equipment disclosed in utility model patent CN2564567Y and the car wash wastewater treatment and recycling device disclosed in utility model patent CN212894230U to treat and reuse wastewater.

[0003] However, during use, it was found that the existing wastewater treatment device has a relatively simple structure, and it is inconvenient to clean the filter sand after long-term use, and it is also inconvenient to replace the filter sand in different locations, resulting in poor practicality. Therefore, there is an urgent need for an energy-saving car wash wastewater sand filtration purification and reuse device to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an energy-saving car wash wastewater sand filtration purification and reuse device that pours filter sand into a support mechanism and discharges car wash wastewater into a filtration mechanism. The car wash wastewater is filtered through the filter sand in the support mechanism and the filtration mechanism. After the equipment has been used for a long time, the filter sand in the support mechanism is cleaned through a cleaning mechanism, thereby improving the practicality of the equipment.

[0005] This utility model discloses an energy-saving car wash wastewater sand filter purification and reuse device, which includes a filtration mechanism; it also includes a support mechanism and a cleaning mechanism, both of which are installed on the filtration mechanism. The filtration mechanism works in conjunction with the support mechanism to filter car wash wastewater, and the cleaning mechanism cleans the filter sand. Pour the filter sand into the support mechanism and discharge the car wash wastewater into the filtration mechanism. The car wash wastewater is filtered through the filter sand in the support mechanism and the filtration mechanism. After the equipment has been used for a long time, clean the filter sand in the support mechanism through the cleaning mechanism to improve the practicality of the equipment.

[0006] Preferably, the filtration mechanism includes a filter box, an inlet valve, a drain valve, and an activated carbon adsorption plate. The inlet valve is installed at the bottom of the filter box, and the drain valve and the activated carbon adsorption plate are both installed on the support mechanism. The support mechanism seals the inside of the filter box and positions the activated carbon adsorption plate inside the filter box. Then, the car wash wastewater is discharged into the filter box through the inlet valve. The filter sand in the support mechanism filters the impurities in the car wash wastewater, and the activated carbon adsorption plate adsorbs the odors in the car wash wastewater. Finally, the filtered car wash wastewater is discharged through the drain valve.

[0007] Preferably, the support mechanism includes multiple sets of hydraulic cylinders, a sealing plate, a rotating shaft, multiple sets of mesh baskets, and a drive motor. The sealing plate is installed on top of the multiple sets of hydraulic cylinders, the rotating shaft is rotatably installed on the sealing plate, the multiple sets of mesh baskets are all installed on the rotating shaft, the drive motor is installed on top of the sealing plate, and the drive motor provides power to the rotating shaft. The drain valve is installed on the sealing plate. Filter sand is poured into the multiple sets of mesh baskets, and the particle size of the filter sand in the multiple sets of mesh baskets gradually decreases from bottom to top. Then, the multiple sets of hydraulic cylinders retract, extending the multiple sets of mesh baskets into the filter box, and the sealing plate covers the top of the filter box to seal the top of the filter box. Then, the car wash wastewater in the filter box flows from bottom to top, and the filter sand in the multiple sets of mesh baskets cleans the impurities in the car wash wastewater. After the equipment has been used for a long time, the multiple sets of hydraulic cylinders extend, and the drive motor is turned on, causing the rotating shaft to drive the multiple sets of mesh baskets to rotate, and the filter sand in the multiple sets of mesh baskets is backwashed by the cleaning mechanism.

[0008] Preferably, each of the multiple sets of mesh baskets is provided with a sealing ring on its outer wall to prevent car wash wastewater from flowing through the gap between the mesh basket and the filter box.

[0009] Preferably, the cleaning mechanism includes a support shaft, a spring, a gear ring, a second drive motor, a gear, a water spray pipe, multiple sets of spray nozzles, and a pressurizing mechanism. The support shaft is slidably mounted on the side end of the filter box. The spring is fitted onto the support shaft, with one end of the spring rotatably connected to the bottom of the support shaft and the other end of the spring mounted on the side end of the filter box. The gear ring is fitted onto the support shaft. The second drive motor is fixedly mounted on the side end of the filter box. The gear is mounted on the output shaft of the second drive motor. The gear and the gear ring are meshed, and the gear ring can slide up and down while meshing with the gear. The water spray pipe is fixedly installed on the support shaft, and multiple sets of nozzles are installed on the water spray pipe. The pressurization mechanism is installed on the filter box. After the sealing plate rises, the mesh basket moves to the top of the filter box. At the same time, the support shaft rises due to the elasticity of the spring, moving the water spray pipe to the top of the filter box. By turning on the second drive motor, the support shaft is driven to rotate through the meshing of the gear and gear ring, moving the water spray pipe to the top of the mesh basket. Then, the pressurized water is discharged into the water spray pipe through the pressurization mechanism. The water is sprayed onto the filter sand in the mesh basket through multiple sets of nozzles to backwash the filter sand.

[0010] Preferably, the pressurizing mechanism includes a pressurizing cylinder, a drain pipe, a hose, a one-way valve, a piston, and a second hydraulic cylinder. The pressurizing cylinder is mounted on the filter box, the drain pipe is mounted on the pressurizing cylinder, and the drain pipe is connected to the interior of the spray pipe through the hose. The one-way valve is mounted on the top front end of the pressurizing cylinder, the piston is slidably mounted in the pressurizing cylinder, and the second hydraulic cylinder is fixedly mounted on the bottom of the pressurizing cylinder, with its top connected to the piston. Water is discharged into the pressurizing cylinder through the one-way valve, while the second hydraulic cylinder contracts, causing the piston to descend. After the second hydraulic cylinder contracts to its limit, it rapidly extends, the one-way valve closes, and the piston rapidly rises, pressurizing the water in the pressurizing cylinder. The pressurized water then passes through the drain pipe and the hose in sequence and enters the spray pipe.

[0011] Preferably, a drain valve is provided at the bottom of the side of the filter box to facilitate the discharge of wastewater from the filter box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: filter sand is poured into the support mechanism, and car wash wastewater is discharged into the filtration mechanism. The car wash wastewater is filtered through the filter sand in the support mechanism and the filtration mechanism. After the equipment has been used for a long time, the filter sand in the support mechanism is cleaned through the cleaning mechanism, thereby improving the practicality of the equipment.
