Description

Technical Field

[0001] This utility model relates to the field of water recycling technology, specifically to a water recycling and filtration device for linen washing equipment. Background Technology

[0002] Linen washing equipment is a professional system designed for washing large quantities of linens (such as sheets, duvet covers, towels, tablecloths, etc.). This equipment is commonly used in hotels, hospitals, restaurants, laundries, and any place that requires the cleaning and management of large quantities of linens.

[0003] The washing of linens generates a large amount of wastewater. If discharged directly without treatment, it will cause serious pollution to water bodies and damage the ecological environment. Through water recycling and filtration devices, the wastewater generated by the linen washing equipment can be collected and filtered, reducing environmental pollution and protecting water resources and the ecological environment. The filtration device is generally equipped with a filter screen to intercept and filter impurities in the washing water. After long-term operation, impurities will accumulate on the surface of the filter screen, affecting the filtration effect. Under normal circumstances, the filter screen needs to be manually inspected and maintained regularly, which not only increases labor and time costs, but may also lead to filter screen blockage problems that cannot be solved in time due to human negligence or misjudgment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 One embodiment of this utility model is a water recovery and filtration device for linen washing equipment, comprising: a filter device body 1, and further comprising...

[0024] Water inlet pipe 3 is located at the top of one side of the filter device body 1. By connecting the water inlet pipe 3 on the filter device body 1 to the water outlet pipe of the linen washing equipment, the wastewater generated by the linen washing equipment enters the filter device body 1 through the water inlet pipe 3.

[0025] A water inlet channel 19 is provided at one end of the water inlet pipe 3, and a ball stopper 18 is provided at the center of the water inlet pipe through a return spring 17.

[0026] When water flows into the inlet pipe 3, it exerts pressure on the plug ball 18, causing it to squeeze the return spring 17 and open the inlet channel 19 to facilitate water inflow. When sewage attempts to flow in the reverse direction, the plug ball 18 is squeezed in the reverse direction, causing the return spring 17 to stretch and the plug ball 18 to block the inlet channel 19, thus preventing untreated sewage from flowing back into the linen washing equipment and causing secondary pollution.

[0027] The ball stopper 18 is pressed tightly against one end of the water inlet channel 19, and a sealing ring 20 is provided on the inner edge of the water inlet channel 19 near the end of the ball stopper 18 to increase the sealing performance after the ball stopper 18 and the water inlet channel 19 are connected.

[0028] Guide grooves 21 are provided on both sides of the inside of the water inlet pipe 3, and guide blocks matching the guide grooves 21 are provided on both sides of the ball plug 18 to restrict the position of the reset spring 17 so that it is not easy to twist or deviate.

[0029] Filter screen 5 is located on one side inside the main body 1 of the filter device. After sewage enters the main body 1 of the filter device, it is first intercepted and filtered by the filter screen 5 to remove impurities.

[0030] A partition plate 12 is provided in the center of the main body 1 of the filter device, and a water outlet is provided on the top of the partition plate 12. An ultraviolet germicidal lamp 11 is provided on one side of the partition plate 12. The filtered water enters the irradiation range of the ultraviolet germicidal lamp 11 through the water outlet on the partition plate 12, which can effectively sterilize and disinfect the water and improve the safety of the water quality.

[0031] Two sets of reflectors 7 are rotatably connected to the filter device body 1 on one side of the ultraviolet germicidal lamp 11 via rotating seats.

[0032] It can reflect the light emitted by the ultraviolet germicidal lamp 11, so that it can be more concentrated on the target area, which helps to ensure that the target area receives sufficient ultraviolet radiation and achieves the expected sterilization and disinfection effect.

[0033] The filter device body 1 on one side of the reflector 7 is equipped with an electric push rod 9. The output end of the electric push rod 9 is connected to the reflector 7 through a telescopic rod. The angle of the reflector 7 can be adjusted by extending and shortening the electric push rod 9, which can adapt to different illumination needs, optimize the lighting effect and avoid light interference. The bottom end of the filter device body 1 on the other side is provided with a water outlet 10 for exporting filtered water.

[0034] Differential pressure sensor 6 is located at one end of the top of the filter device body 1. The differential pressure sensor 6 is connected to a high pressure end 14 and a negative pressure end 15 via wires. The high pressure end 14 and the negative pressure end 15 are respectively provided with the front and rear ends of the filter screen 5, and the differential pressure between the front and rear ends of the filter screen 5 is monitored in real time.

[0035] A lead screw 2 is installed inside the filter device body 1 on the side of the filter screen 5 near the water inlet pipe 3. A drive block 4 is sleeved on the lead screw 2, and a cleaning brush 16 is installed on the side of the drive block 4 near the filter screen 5.

[0036] The base 8 is located at the bottom of the filter device body 1, and a drive motor 13 is fixed inside the base 8. The output end of the drive motor 13 is connected to the lead screw 2.

[0037] When the pressure difference across the filter screen 5 exceeds the preset threshold, the drive motor 13 drives the lead screw 2 to rotate, causing the drive block 4 to move down along the lead screw 2, and the cleaning brush 16 on one side scrapes away the impurities accumulated on the surface of the filter screen 5.

[0038] Since clogging of filter screen 5 can cause an increase in the pressure difference between the inlet and outlet sides, the differential pressure sensor 6 monitors the pressure difference changes before and after filter screen 5 and automatically cleans filter screen 5, reducing the need for manual inspection, disassembly, cleaning and reinstallation of filter screen 5, thereby reducing labor and time costs.

[0039] The specific models and specifications of the differential pressure sensor 6, electric push rod 9, ultraviolet germicidal lamp 11, and drive motor 13 need to be determined based on the specifications and parameters of the device. The selection and calculation method is existing technology, so it will not be described in detail here.

[0040] Working Principle: In this embodiment, the inlet pipe 3 on the filter device body 1 is connected to the outlet pipe of the linen washing equipment. Wastewater generated by the linen washing equipment enters the filter device body 1 through the inlet pipe 3. When the water flows into the inlet pipe 3, it exerts pressure on the plug ball 18, causing it to squeeze the return spring 17 and simultaneously opening the inlet channel 19 to facilitate water flow. When the wastewater attempts to flow backward, the plug ball 18 is squeezed in the opposite direction, causing the return spring 17 to stretch and the plug ball 18 to block the inlet channel 19, preventing untreated wastewater from flowing back into the linen washing equipment and causing secondary pollution. After entering the filter device body 1, the wastewater is first intercepted and filtered by the filter screen 5, and then enters the irradiation range of the ultraviolet germicidal lamp 11 through the water outlet on the partition plate 12. This effectively sterilizes and disinfects the water, improving water quality safety. The reflector 7 reflects the light emitted by the ultraviolet germicidal lamp 11, making it more concentrated on the target area. This helps ensure that the target area receives sufficient ultraviolet irradiation to achieve the expected sterilization and disinfection effect. In addition, by connecting the high-pressure end 14 and the negative-pressure end 15 of the differential pressure sensor 6 to the front and rear ends of the filter screen 5 respectively, the differential pressure between the front and rear ends of the filter screen 5 is monitored in real time. When the differential pressure exceeds the preset threshold, the drive motor 13 drives the lead screw 2 to rotate, causing the drive block 4 to move down along the lead screw 2. The cleaning brush 16 on one side scrapes away the impurities accumulated on the surface of the filter screen 5. Since the filter screen 5 is clogged, the pressure difference between the inlet and outlet sides will increase. Therefore, the differential pressure sensor 6 monitors the pressure difference changes generated before and after the filter screen 5 and automatically cleans the filter screen 5, reducing the need for manual inspection, disassembly, cleaning and reinstallation of the filter screen 5, thereby reducing labor and time costs.
