Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater recycling device for coated glass production. Background Technology

[0002] The production of coated glass generates wastewater. Before coating, the glass undergoes surface treatment processes such as cleaning, etching, and varnishing. These processes use a large amount of cleaning agents and chemicals, resulting in wastewater containing impurities and chemicals. If this wastewater is discharged directly into rivers without treatment, it will impact the ecological environment near the rivers. Wastewater treatment mainly includes the following steps: first, filtering impurities (such as glass fragments) from the wastewater; then, adding agents (such as coagulants and flocculants) to react with suspended solids in the wastewater; and finally, discharging it into a sedimentation tank for further treatment.

[0003] For example, the wastewater treatment filtration device disclosed in patent CN219489626, although it uses stirring blades to agitate the filtered water in the storage tank to accelerate the mixing of the filtered water and disinfectant, thereby speeding up the disinfection of the filtered water, has the following drawbacks in actual use: since the filter plate is fixed in the slot, when the wastewater comes into contact with the filter plate, impurities on it may clog some of the filter holes on the filter plate, thus affecting its filtration effect. Therefore, it needs to be improved. Utility Model Content

[0031] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0032] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0033] Please see Figures 1-2This embodiment of a wastewater recycling device for coated glass production includes a recycling tank 100. The recycling tank 100 has a cavity with an open top. A partition frame 220 is provided inside the cavity, dividing the cavity into an upper cavity and a lower cavity. A liftable filter box 200 is provided in the upper cavity. The filter box 200 has an open top and its bottom end abuts against the partition frame 220. The bottom end of the filter box 200 has multiple filter holes 301. A driving component for driving the filter box 200 to move up and down is provided in the lower cavity. A stirring assembly is also provided in the lower cavity. The stirring assembly includes a swing plate 230 that is arranged opposite to each other and can swing. The driving component can also drive the swing plate 230 to swing.

[0034] In this embodiment, a detachable cover plate 110 is provided at the opening of the upper cavity by screws. The cover plate 110 is provided with a water inlet pipe 111. A dosing pipe 250 and a water outlet pipe 101 are respectively provided on the side wall of the recovery tank 100. Both the water outlet pipe 101 and the dosing pipe 250 are provided with openable and closable valves. When treating wastewater, the wastewater is first added into the filter box 200 through the water inlet pipe 111. After being filtered through the filter holes 301, it falls into the lower cavity, leaving impurities (such as glass fragments) in the filter box 200 to achieve the recovery of impurities for reuse. The chemicals (such as coagulants and coagulant aids) are added into the lower cavity through the dosing pipe 250. The chemicals and wastewater are mixed by the stirring assembly. After a period of mixing, the valve in the water outlet pipe 101 is opened to discharge the wastewater mixed with chemicals from the water outlet pipe 101 for subsequent treatment.

[0035] In this embodiment, the filter box 200 is height-adjustable, allowing the wastewater and impurities in the filter box 200 to rise and fall accordingly. Compared with the existing method, impurities in the wastewater are less likely to accumulate in the filter holes 301, reducing the possibility of the filter holes 301 being blocked and thus ensuring the filtration effect.

[0036] The mixing component allows for the stirring of wastewater and chemicals in the lower chamber, promoting their mixing.

[0037] The drive unit not only lifts and lowers the filter box 200 to ensure its filtration effect, but also swings the swing plate 230 to promote the mixing of the reagent and wastewater in the lower chamber, giving the drive unit multiple functions.

[0038] Combination Figures 1-6As shown, in this embodiment, a detachable cover plate 110 is provided at the opening of the upper cavity, a plurality of positioning rods 210 are provided opposite to each other on the partition frame 220, a positioning hole 300 is provided on the filter box 200 for the positioning rods 210 to pass through, a spring 211 is provided at the top of the positioning rod 210, the spring 211 is used to push the filter box 200 to move downward, and the driving component includes a rotating shaft 510 disposed in the lower cavity and rotatable, a cam 610 is provided opposite to each other on the rotating shaft 510, the cam 610 is disposed at the bottom end of the filter box 200, and the rotation of the cam 610 is used to push the filter box 200 to move upward.

[0039] In this embodiment, one end of the spring 211 abuts against the bottom end of the cover plate 110, and the other end abuts against the top end of the filter box 200. When the rotating shaft 510 rotates, when the protruding part of the cam 610 contacts the bottom end of the filter box 200, the cam 610 will lift the filter box 200, causing the filter box 200 to move upward. At this time, the spring 211 is compressed. When the protruding part of the cam 610 disengages from the bottom end of the filter box 200, the filter box 200 moves downward under the elastic force of the spring 211. This process is repeated continuously, so that the filter box 200 and the wastewater and impurities inside it continuously rise and fall, thereby reducing the possibility of impurities clogging the filter hole 301.

[0040] The positioning rod 210 and the positioning hole 300 restrict the lifting direction of the filter box 200, meaning it can only move along the extension direction of the positioning rod 210.

[0041] In practical use, when wastewater falls from the inlet pipe 111 into the filter box 200, most of the wastewater will directly pass through the filter hole 301 and fall into the lower cavity. Only a small amount of wastewater and impurities will accumulate at the bottom of the filter box 200. Moreover, the lifting range of the filter box 200 is small. During the continuous lifting and lowering process of the filter box 200, the wastewater and impurities in the filter box 200 are not easy to spill out from the upper opening of the filter box 200, so that the wastewater falls into the lower cavity without being filtered. After the treatment of a batch of wastewater is completed, the cover plate 110 can be removed, and then the filter box 200 can be taken out and cleaned.

[0042] In order to cushion the rising and falling filter box 200, a rubber pad is provided at the top of the partition frame 220. This reduces the impact between the filter box 200 and the partition frame 220 when they come into contact, thereby reducing the damage caused by the impact. In addition, there is a certain gap between the filter box 200 and the side wall of the upper cavity, so that the filter box 200 will not rub against the inner wall of the recycling box 100 when it rises and falls.

[0043] Combination Figures 1-6As shown, in this embodiment, the bottom end of the lower cavity is provided with a base plate, and the base plate is provided with a rotatable swing shaft 620. The swing plate 230 is provided on the swing shaft 620. A rotating wheel 611 is also provided on one side of the cam 610. The rotating wheel 611 is provided with an inclined groove 612 along its radial direction. A fixed rod 621 is provided on the swing plate 230. The fixed rod 621 is abutted against the inclined groove 612. The rotating wheel 611 rotates to drive the swing plate 230 to swing.

[0044] In this embodiment, a bearing is provided in the base plate, and the lower end of the swing shaft 620 extends into the bearing. This allows the swing shaft 620 to swing within the lower cavity. When the cam 610 rotates, it drives the rotating wheel 611 to rotate. When the protruding part of the inclined groove 612 contacts the fixing rod 621 on one side of the swing plate 230, it drives one side of the swing plate 230 to swing away from the cam 610. At this time, the fixing rod 621 on the other side of the swing plate 230 contacts the recessed part of the inclined groove 612. The rotating wheel 611 continues to rotate. When the protruding part of the inclined groove 612 contacts the fixing rod 621 on the other side of the swing plate 230, it drives one side of the swing plate 230 to swing closer to the cam 610. This process is repeated continuously, causing the swing plate 230 to swing continuously and mix the wastewater and medicine in the lower cavity.

[0045] Specifically, a second motor 102 for driving the rotating shaft 510 to rotate is provided on the side wall of the recycling bin 100. A bearing is provided on the side wall of the recycling bin 100, and the rotating shaft 510 is rotatably installed in the recycling bin 100 through the bearing. A sealing gasket is also provided on the side wall of the recycling bin 100, which can prevent wastewater from leaking out of the recycling bin 100.

[0046] Combination Figures 1-7 As shown, in this embodiment, the stirring assembly also includes a first stirring shaft 240 and a second stirring shaft 500 disposed in the lower cavity. Both the first stirring shaft 240 and the second stirring shaft 500 are rotatably disposed. The recycling tank 100 is also provided with an equipment cavity 700. The bottom ends of the first stirring shaft 240 and the second stirring shaft 500 extend into the equipment cavity 700. The equipment cavity 700 is provided with an asynchronous component that drives the first stirring shaft 240 and the second stirring shaft 500 to rotate in opposite directions.

[0047] In this embodiment, a plurality of stirring blades 600 are provided on the first stirring shaft 240 and the second stirring shaft 500 along their axial direction. When the first stirring shaft 240 and the second stirring shaft 500 rotate, they can mix the wastewater and the medicine in the lower chamber.

[0048] The asynchronous component enables the first stirring shaft 240 and the second stirring shaft 500 to rotate in opposite directions. This allows the wastewater and reagents near the first stirring shaft 240 and the second stirring shaft 500 to rotate in opposite directions as well. In conjunction with the swing plate 230, this causes turbulence in the wastewater in the lower chamber during mixing, resulting in better mixing of the reagents and wastewater.

[0049] Combination Figures 1-7 As shown, in this embodiment, the asynchronous component includes a rotating rod 710 that is rotatable and located within the equipment cavity 700. A first pulley 730 is provided on a second stirring shaft 500 located within the equipment cavity 700. A second pulley 712 is provided on the rotating rod 710. A connecting belt 731 is sleeved on the second pulley 712 and the first pulley 730. The rotation of the second stirring shaft 500 is used to drive the rotating rod 710 to rotate in the same direction. A first gear 711 is also provided on the rotating rod 710. A second gear 701 is also provided on the first stirring shaft 240 located within the equipment cavity 700. The second gear 701 is meshed with the first gear 711. The rotation of the rotating rod 710 is used to drive the first stirring shaft 240 to rotate in the opposite direction.

[0050] In this embodiment, when the second stirring shaft 500 rotates, it can drive the first pulley 730 to rotate. Under the transmission of the connecting belt 731, the second pulley 712 drives the rotating rod 710 to rotate in the same direction. Under the transmission of the second gear 701 and the first gear 711, the second stirring shaft 500 and the first stirring shaft 240 can rotate in opposite directions.

[0051] Among them, the first pulley 730 and the second pulley 712 are toothed pulleys, and the connecting belt 731 is a toothed belt. The inner circumference of the connecting belt 731 is toothed and it meshes with the toothed pulley. As a result, the connecting belt 731 is not easy to slip between the first pulley 730 and the second pulley 712, so as to ensure the transmission effect.

[0052] Specifically, the bottom of the recycling bin 100 is provided with a first motor for driving the second stirring shaft 500 to rotate, and the bottom of the recycling bin 100 is provided with a support leg 103, which can raise the recycling bin 100 so that the first motor can be installed at the bottom of the recycling bin 100.

[0053] The base plate is equipped with bearings, and the first stirring shaft 240 and the second stirring shaft 500 are rotatable on the base plate through the bearings. The base plate is also equipped with a sealing gasket, which can prevent wastewater in the lower chamber from flowing into the equipment chamber 700.

[0054] In this embodiment, when treating wastewater, the wastewater is first added into the filter box 200 through the inlet pipe 111. After being filtered through the filter holes 301, it falls into the lower chamber. The second motor 102 is started, causing the rotating shaft 510 to rotate, which causes the filter box 200 and the wastewater inside it to rise and fall continuously, and causes the swing plate 230 to swing continuously. The reagents (such as coagulants and coagulant aids) are added into the lower chamber through the dosing pipe 250. The first motor is started, which causes the second stirring shaft 500 and the first stirring shaft 240 to rotate in opposite directions to mix the reagents and wastewater. After mixing for a period of time, the valve in the outlet pipe 101 is opened, and the wastewater mixed with the reagents is discharged from the outlet pipe 101.

[0055] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
