Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and in particular to a wastewater filtration and recycling device for a glass cleaning machine. Background Technology

[0002] After glass undergoes deep processing steps such as coating, screen printing, and tempering, a layer of volatile substances forms on the glass surface, and its temperature reaches approximately 70°C. To ensure the glass's light transmittance and effectively cool it, a glass washing machine is needed to clean both sides of the glass, thus achieving the purpose of cleaning and cooling. Common glass washing machines are generally equipped with water tanks. The water used in the washing process is collected and treated in the tanks, and then pumped back to the glass washing machine for further cleaning, achieving the purpose of water recycling.

[0003] For example, Chinese patent CN219943800U, with authorization announcement date of November 3, 2023, discloses "A water tank structure and a glass washing machine". In the process of wastewater circulation, the wastewater is filtered through a wastewater filtration device, and a drainage auxiliary device is used to prevent impurities from being discharged from the bottom of the tank, so as to achieve recycling.

[0004] The aforementioned comparative patent has the following problems: First, the water inside the tank is circulating, and impurities will move with the water flow. As a result, a lot of impurities will flow out from the drainage auxiliary device, which will put a great burden on the filtration of the wastewater filter, leading to the problem of frequent cleaning or replacement of the wastewater filter. Summary of the Invention

[0005] The purpose of this invention is to provide a wastewater filtration and circulation device for glass washing machines, which facilitates the removal of impurities.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a wastewater filtration and circulation device for a glass washing machine, comprising a water tank, a wastewater main pipe connected to the water tank, an outlet pipe connected to the water tank, a water pump installed on the outlet pipe, and a filtration mechanism. Multiple filter tanks are arranged on one side of the water tank. Multiple wastewater drain pipes communicating with the filter tanks are installed on the wastewater main pipe. Each filter tank has a drain pipe with drainage holes arranged in a circumferential array and extending out of the filter tank at its bottom. The filtration mechanism includes multiple filter cylinders, each installed on a plurality of drain pipes, for filtering wastewater flowing from the drain pipes. The filtration mechanism includes a filter cylinder rotatably installed outside the drain pipes, a first elastic limiting component installed at the bottom of the filter tank and filter cylinder and supporting the rotation of the filter cylinder, a filter screen wound around the periphery of the filter cylinder, and soft magnetic strips wrapped around the upper and lower edges of the filter screen. Insertion strips are provided at both ends of the filter screen along its length, one of which is vertically downward. The filter screen is inserted into the circumference of the filter cylinder; it also includes multiple winding shafts rotatably disposed in the filter tank, a second elastic limiting component disposed between the winding shaft and the filter tank and preventing the winding shaft from rotating, and a winding drive mechanism disposed on the water tank and simultaneously driving the multiple winding shafts to rotate. Another insertion strip of the filter screen is inserted into the circumference of the winding shaft in a vertically downward direction. The wastewater circulation filtration treatment method includes the following steps: (S1) Wastewater enters multiple filter tanks along the wastewater main pipe and wastewater branch pipe; (S2) Wastewater permeates the rolled filter screen for filtration and is discharged from the filter cylinder and drain pipe, enters the water tank, and is discharged from the outlet pipe; (S3) When impurities adhere to the surface of the rolled filter screen and affect the filtration efficiency, the winding drive mechanism moves to the winding shaft of the corresponding filter tank, overcomes the elastic force of the first elastic limiting component and the second elastic limiting component, and causes the winding shaft and filter cylinder to rotate so that the part of the filter screen with impurities on the surface is wound on the winding shaft to ensure the filtration efficiency of the filter cylinder and the rolled filter screen.

[0007] By adopting the above technical solution, the wastewater recycling filtration treatment method includes the following steps: (S1) Wastewater enters multiple filter tanks along the wastewater main pipe and wastewater branch pipes; (S2) Wastewater permeates the rolled-up filter screen for filtration, and is discharged from the filter cylinder and drain pipe, enters the water tank, and is discharged from the outlet pipe; (S3) When impurities adhere to the surface of the rolled-up filter screen, affecting the filtration efficiency, the winding drive mechanism moves to the winding shaft of the corresponding filter tank, overcoming the elastic force of the first elastic limiting component and the second elastic limiting component, causing the winding shaft and filter cylinder to rotate, so that the part of the filter screen with impurities on its surface is wound up on the winding shaft, so as to ensure... The process ensures the filtration efficiency of the filter cartridge and the rolled filter screen. Multiple filter grooves are used to guarantee filtration efficiency. Impurities on the surface of the filter screen are removed by winding it up, ensuring filtration efficiency. Soft magnetic strips are used to create gaps between adjacent filter screen layers, ensuring filtration efficiency and providing support for the upper and lower ends of the filter screen. During winding, the tension on the filter screen must overcome the elastic force of the first elastic limiting component. The soft magnetic strips strengthen the structure of the filter screen, making it less prone to deformation during winding and allowing it to self-adhere and fix itself when rolled up.

[0008] A further feature of the present invention is that during the process of the filter screen, which is wound and arranged around the periphery of the filter cylinder, being wound up by the winding shaft, the outer surface of the filter screen with impurities attached to it is wound up into the inner surface.

[0009] By adopting the above technical solution, during the process of the filter screen, which is wound and arranged around the filter cylinder, being wound by the winding shaft, the outer surface of the filter screen with impurities attached to it is wound into the inner surface, so that the impurities on the filter screen are not easily removed by the water flow.

[0010] A further feature of the present invention is that: a control valve is provided on the wastewater pipe; the filter cartridge is detachably disposed on the outside of the drainage pipe; the winding shaft is detachably disposed in the filter tank; and the winding drive mechanism is detachably disposed from the multiple winding shafts.

[0011] By adopting the above technical solution, when all the rolled-up filter screens on the filter cartridge are wound onto the take-up shaft, the control valve for the wastewater pipe of the corresponding filter tank can be closed first. After the wastewater in the filter tank is discharged, the filter cartridge and the take-up shaft can be connected. Since the take-up drive mechanism is not directly connected to the take-up shaft, it is convenient to disassemble and replace.

[0012] A further configuration of the present invention is as follows: the upper end of the drainage pipe is sealed, the filter cylinder is sleeved inside the drainage pipe, the bottom of the filter cylinder is provided with a rubber sealing ring that abuts against the bottom of the filter tank, the periphery of the filter cylinder is provided with an annular embedding groove for winding the filter screen, the upper and lower ends of the filter cylinder are provided with a first insertion groove communicating with the annular embedding groove, and one of the insertion strips is inserted into the first insertion groove; the drainage pipe is provided with a connecting shaft extending through the top of the filter cylinder, the upper surface of the filter cylinder is provided with a plurality of hemispherical limiting holes arranged in a circumferential array, and the first elastic limiting component includes a limiting sleeve that is telescopically mounted on the connecting shaft and has a plurality of limiting protrusions on its lower surface that match the limiting holes, a compression spring sleeved on the connecting shaft, and an anti-detachment adjustment cover that is threadedly connected to the upper end of the connecting shaft and realizes the adjustment of the initial elastic force of the compression spring.

[0013] By adopting the above technical solution, after the filter cartridge is installed, the rubber sealing ring at the bottom of the filter cartridge abuts against the bottom of the filter tank to seal it. The top of the filter cartridge is subjected to downward pressure by the compression spring of the first elastic limiting component, and the limiting protrusion of the limiting sleeve on the telescopic connecting shaft matches the limiting hole on the upper surface of the filter cartridge to prevent the filter cartridge from rotating. At the same time, when the filter screen is wound up, the filter screen exerts a pulling force on the periphery of the filter cartridge. At this time, the elastic force of the first elastic limiting component can be overcome to allow the filter cartridge to rotate. After rotation, the limiting protrusion and the limiting hole are used to re-limit the filter cartridge.

[0014] A further configuration of the present invention is as follows: a threaded hole is provided in the filter groove, a threaded seat threaded in the threaded hole is rotatably connected to the lower end of the take-up shaft, a quadrilateral limiting end is provided at the lower end of the take-up shaft, a second insertion groove is provided on the periphery of the take-up shaft, and one of the insertion strips is inserted into the second insertion groove; the second elastic limiting component includes a metal spring sheet in the shape of a "U" provided on the side wall of the filter groove, a fixing screw provided between the metal spring sheet and the inner wall of the filter groove, the two sides of the metal spring sheet abut against the two sides corresponding to the limiting end, and the two sides of the metal spring sheet expand outward during the rotation of the take-up shaft.

[0015] By adopting the above technical solution, during the rotation of the winding shaft, the two sides of the metal spring sheet expand outwards. When the winding shaft stops rotating, the two sides of the metal spring sheet return to their original position and abut against the two sides corresponding to the limiting end, thereby preventing the winding shaft from rotating on its own.

[0016] A further feature of the present invention is that the upper end of the take-up shaft is provided with a rotating end in the shape of a regular polygon; the take-up drive mechanism includes a flipping frame hinged to one side of the water tank, a fixing component disposed between the other side of the flipping frame and the filter tank, and a drive component disposed on the flipping frame and sleeved on the rotating end of multiple take-up shafts to drive multiple take-up shafts to rotate.

[0017] By adopting the above technical solution, the drive component of the winding drive mechanism is installed on the flipping frame. At this time, after the flipping frame rotates, it can be separated from multiple winding shafts, which facilitates the disassembly and replacement of the winding shafts.

[0018] A further configuration of the present invention is as follows: the drive assembly includes a plurality of support rods rotatably mounted on the tilting frame, a rotating sleeve mounted at the lower end of the support rods and for fitting onto the rotating end, a plurality of first pulleys mounted at one end of the support rods passing through the tilting frame, a reduction motor mounted on the tilting frame, a second pulley mounted on the output shaft of the reduction motor, and a chain belt mounted between the plurality of first pulleys and second pulleys.

[0019] By adopting the above technical solution, when the geared motor is running, the chain belt, the first pulley, and the second pulley can drive multiple support rods and rotating sleeves to rotate, thereby simultaneously driving multiple winding shafts to rotate.

[0020] A further configuration of the present invention is as follows: the fixing component includes a first connecting seat disposed on the top of one side of the filter tank, a second connecting seat disposed on the side of the flipping frame and corresponding to the first connecting seat, and a fixing knob bolt threaded onto the first connecting seat after passing through the second connecting seat.

[0021] By adopting the above technical solution, the fixing component includes a first connecting seat set at the top of one side of the filter tank, a second connecting seat set on the side of the flipping frame and corresponding to the first connecting seat, and a fixing knob bolt that passes through the second connecting seat and is threaded onto the first connecting seat, so as to fix the flipping frame.

[0022] A further feature of the present invention is that: a filter partition is provided inside the water tank to divide the water tank into an inlet area and a drain area; multiple filter tanks are located above the inlet area; the outlet pipe is connected to the drain area; and the water in the inlet area flows into the drain area after passing through the filter partition.

[0023] By adopting the above technical solution, the water tank is divided into an inlet area and a drain area by setting up a baffle. The water in the inlet area goes to the drain area after passing through the filter baffle, thereby further filtering the wastewater.

[0024] A further provision of the present invention is that a third insertion groove extending vertically is provided inside the water tank, and the filter baffle is inserted into the third insertion groove.

[0025] By adopting the above technical solution, the detachable design of the filter baffle allows for cleaning or replacement after disassembly. Attached Figure Description

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example: A wastewater filtration and circulation device for a glass washing machine, such as Figure 1 and Figure 2 As shown, the system includes a water tank 1, a wastewater main pipe 2 connected to the water tank 1, a water outlet pipe 3 connected to the water tank 1, a water pump 4 installed on the water outlet pipe 3, and a filtration mechanism 5. Multiple filter tanks 6 are arranged on one side of the water tank 1. Multiple wastewater branch pipes 21 connected to the filter tanks 6 are installed on the wastewater main pipe 2. Control valves 22 are installed on the wastewater branch pipes 21. Drainage pipes 61 with drainage holes arranged in a circular array around the periphery of the filter tanks 6 and extending out of the bottom of the filter tanks 6 are installed within the filter tanks 6.

[0031] like Figures 1 to 4 As shown, the filtration mechanism 5 includes multiple drain pipes 61 respectively, for filtering wastewater flowing out of the drain pipes 61.

The filter screen 53 has insert strips 531 at both ends along its length, one of which is inserted into the filter cylinder 51 along the vertical downward direction.

[0032] like Figure 2 , Figure 3 and Figure 5 As shown, the filter cartridge 51 is detachably mounted on the outside of the drain pipe 61. The upper end of the drain pipe 61 is sealed, and the filter cartridge 51 is fitted inside the drain pipe 61. The bottom of the filter cartridge 51 is provided with a rubber sealing ring 511 that abuts against the bottom of the filter tank 6. The periphery of the filter cartridge 51 is provided with an annular embedding groove 512 for the filter screen 53 to be rolled and wound. The upper and lower ends of the filter cartridge 51 are provided with a first insertion groove 513 that communicates with the annular embedding groove 512, and one of the insertion strips 531 is inserted into the first insertion groove 513. A connecting shaft 62 is provided on the drainage pipe 61, extending through the top of the filter cylinder 51. The upper surface of the filter cylinder 51 is provided with a plurality of hemispherical limiting holes 514 arranged in a circumferential array. The first elastic limiting component 52 includes a limiting sleeve 521 that is telescopically mounted on the connecting shaft 62 and has a plurality of limiting protrusions 5211 on its lower surface that match the limiting holes 514, a compression spring 522 that is sleeved on the connecting shaft 62, and an anti-detachment adjusting cover 523 that is threadedly connected to the upper end of the connecting shaft 62 and realizes the adjustment of the initial elastic force of the compression spring 522.

[0033] like Figures 1 to 5 As shown, it also includes multiple take-up shafts 7 rotatably disposed within the filter tank 6, a second elastic limiting component 8 disposed between the take-up shafts 7 and the filter tank 6 and preventing the take-up shafts 7 from rotating, and a take-up drive mechanism 9 disposed on the water tank 1 and simultaneously driving the multiple take-up shafts 7 to rotate. Another insert strip 531 of the filter screen 53 is inserted into the periphery of the take-up shaft 7 in a vertically downward direction. During the process of the filter screen 53, which is wound around the periphery of the filter cylinder 51, being taken up by the take-up shaft 7, the outer surface of the filter screen 53 with impurities attached is taken up as the inner surface.

[0034] like Figures 1 to 3 As shown, the take-up shaft 7 is detachably installed in the filter tank 6. The filter tank 6 is provided with a threaded hole 63. The lower end of the take-up shaft 7 is rotatably connected to a threaded seat 71 that is threaded into the threaded hole 63. The lower end of the take-up shaft 7 is provided with a square-shaped limiting end 72. The circumference of the take-up shaft 7 is provided with a second insertion groove 73, and one of the insertion strips 531 is inserted into the second insertion groove 73.

[0035] like Figures 1 to 3 As shown, the second elastic limiting component 8 includes a metal spring sheet 81 in the shape of a "U" disposed on the side wall of the filter tank 6, and a fixing screw 82 disposed between the metal spring sheet 81 and the inner wall of the filter tank 6. The two sides of the metal spring sheet 81 abut against the two sides corresponding to the limiting end 72. During the rotation of the winding shaft 7, the two sides of the metal spring sheet 81 are stretched outward.

[0036] like Figure 1 , Figure 2 and Figure 6As shown, the upper end of the winding shaft 7 is provided with a rotating end 74 in the shape of a regular polygon, and the winding drive mechanism 9 is detachably disposed from the multiple winding shafts 7. The winding drive mechanism 9 includes a tilting frame 91 hinged to one side of the water tank 1, a fixing component 92 disposed between the other side of the tilting frame 91 and the filter tank 6, and a drive component 93 disposed on the tilting frame 91 and fitted onto the rotating end 74 of the multiple winding shafts 7 to drive the multiple winding shafts 7 to rotate. The fixing component 92 includes a first connecting seat 921 disposed on the top of one side of the filter tank 6, a second connecting seat 922 disposed on the side of the tilting frame 91 and corresponding to the first connecting seat 921, and a fixing knob bolt 923 that passes through the second connecting seat 922 and is threaded onto the first connecting seat 921. The drive assembly 93 includes multiple support rods 931 rotatably mounted on the tilting frame 91, a rotating sleeve 932 located at the lower end of the support rods 931 and for fitting onto the rotating end 74, multiple first pulleys 933 located at the end of the support rods 931 that pass through the tilting frame 91, a reduction motor 934 mounted on the tilting frame 91, a second pulley 935 located on the output shaft of the reduction motor 934, and a chain belt 936 located between the multiple first pulleys 933 and the second pulleys 935. Furthermore, the inner cross-section of the rotating sleeve 932 is larger than the cross-section of the rotating end 74, allowing it to fit onto the rotating end 74 during the rotation of the tilting frame.

[0037] Meanwhile, the water tank 1 is equipped with a filter baffle 11 that divides the water tank 1 into an inlet area 12 and a drain area 13. Multiple filter tanks 6 are located above the inlet area 12, and the outlet pipe 3 connects to the drain area 13. The water in the inlet area 12 flows into the drain area 13 after passing through the filter baffle 11. The water tank 1 is equipped with a third insertion slot 14 extending vertically, and the filter baffle 11 is inserted into the third insertion slot 14.

[0038] The wastewater recycling filtration treatment method includes the following steps: (S1) Wastewater enters multiple filter tanks 6 along the wastewater main pipe 2 and wastewater branch pipe 21; (S2) Wastewater permeates the rolled filter screen 53 for filtration and is discharged from the filter cylinder 51 and drain pipe 61, enters the water tank 1, and is discharged from the outlet pipe 3; (S3) When impurities adhere to the surface of the rolled filter screen 53 and affect the filtration efficiency, the winding drive mechanism 9 moves to the winding shaft 7 of the corresponding filter tank 6, overcoming the elastic force of the first elastic limiting component 52 and the second elastic limiting component 8, so that the winding shaft 7 and the filter cylinder 51 rotate, so that the filter screen 53 with impurities on its surface is partially wound on the winding shaft 7, so as to ensure the filtration efficiency of the filter cylinder 51 and the rolled filter screen 53.

[0039] Implementation Results: The wastewater recycling filtration method includes the following steps: (S1) Wastewater enters multiple filter tanks 6 through the wastewater main pipe 2 and wastewater branch pipe 21; (S2) Wastewater permeates the rolled-up filter screen 53 for filtration and is discharged from the filter cylinder 51 and drain pipe 61, entering the water tank 1 and being discharged from the outlet pipe 3; (S3) When impurities adhere to the surface of the rolled-up filter screen 53, affecting the filtration efficiency, the winding drive mechanism 9 moves to the winding shaft 7 of the corresponding filter tank 6, overcoming the elastic force of the first elastic limiting component 52 and the second elastic limiting component 8, causing the winding shaft 7 and the filter cylinder 51 to rotate, so that the filter screen 53 with impurities on its surface is partially wound onto the winding shaft 7, thereby ensuring filtration efficiency. The filtration efficiency of the cylinder 51 and the rolled filter screen 53 is ensured by setting multiple filter grooves 6. The impurities on the surface of the filter screen 53 are removed by winding it up, thus ensuring filtration efficiency. The soft magnetic strip 54 creates gaps between adjacent layers of filter screens 53, ensuring filtration efficiency and providing support for the upper and lower ends of the filter screen 53. During the winding process, the tension on the filter screen 53 must overcome the elastic force of the first elastic limiting component 52. The soft magnetic strip 54 strengthens the structure of the filter screen 53, making it less prone to deformation during the pulling and winding process. It can also be self-adhesive and fixed when the filter screen 53 is rolled up.

[0040] When all the rolled-up filter screens 53 on the filter cartridge 51 are wound onto the take-up shaft 7, the control valve 22 of the wastewater pipe 21 of the corresponding filter tank 6 can be closed first. After the wastewater in the filter tank 6 is discharged, the filter cartridge 51 and the take-up shaft 7 can be connected. Since the take-up drive mechanism 9 is not directly connected to the take-up shaft 7, it is convenient to disassemble and replace.

[0041] After the filter cartridge 51 is installed, the rubber sealing ring 511 at the bottom of the filter cartridge 51 abuts against the bottom of the filter groove 6 to seal it. The top of the filter cartridge 51 is subjected to downward pressure by the compression spring 522 of the first elastic limiting component 52, and the limiting protrusion 5211 of the limiting sleeve 521 on the telescopic connecting shaft 62 matches the limiting hole 514 on the upper surface of the filter cartridge 51 to prevent the filter cartridge 51 from rotating. At the same time, when the filter screen 53 is wound up, the filter screen 53 exerts a pulling force on the periphery of the filter cartridge 51. At this time, the elastic force of the first elastic limiting component 52 can be overcome to allow the filter cartridge 51 to rotate. After rotation, the limiting protrusion 5211 and the limiting hole 514 are used to re-limit it.

[0042] During the rotation of the take-up shaft 7, the two sides of the metal spring 81 expand outwards. When the take-up shaft 7 stops rotating, the two sides of the metal spring 81 return to their original position and abut against the two corresponding sides of the limit end 72 to prevent the take-up shaft 7 from rotating on its own. The drive assembly 93 of the take-up drive mechanism 9 is mounted on the tilting frame 91. At this time, after the tilting frame 91 rotates, it can be separated from the multiple take-up shafts 7, thereby facilitating the disassembly and replacement of the take-up shafts 7. When the geared motor 934 is running, the chain belt 936, the first pulley 933, and the second pulley 935 can drive the multiple support rods 931 and the rotating sleeve 932 to rotate, thereby simultaneously driving the multiple take-up shafts 7 to rotate.
