Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to wastewater treatment equipment and glass production lines. Background Technology

[0002] In the glass deep processing industry, drilling machines and edging machines require continuous water cooling and rinsing during operation, which generates a large amount of wastewater containing solid residues such as glass powder and particles. If this wastewater is discharged directly, it will not only clog sewer pipes and cause environmental pollution, but also lead to a serious waste of water resources.

[0003] Currently, the common treatment method is to set up a single sedimentation tank, allowing the wastewater to settle naturally in the tank, and then separating the supernatant for reuse or discharge. However, this single sedimentation method has significant drawbacks: First, the wastewater flow directly discharged into the equipment has a strong impact force, which continuously agitates the tank, disrupting the flow field stability in the sedimentation zone, resulting in low sedimentation efficiency and insufficient effluent clarity; second, a large number of extremely fine glass particles remain in the supernatant after one sedimentation, which are difficult to completely remove in a single sedimentation due to their slow settling speed, resulting in unsatisfactory effluent quality, and direct reuse may affect the cleanliness of nozzles in processing equipment or product surfaces. To improve water quality, it is usually necessary to add multi-stage sedimentation tanks or complex filtration systems, which significantly increases the floor space and equipment costs. Utility Model Content

[0004] The purpose of this application is to provide a wastewater treatment device and a glass production line, aiming to solve the problems of how to enhance the purification capacity of the wastewater treatment device and how to reduce energy consumption.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a wastewater treatment device is provided, comprising: a first water tank for storing wastewater; a second water tank for settling solid particles in the wastewater; a first pipe having an inlet end connected to the first water tank and an outlet end connected to the second water tank, the height of the inlet end being greater than the height of the outlet end, wherein the wastewater in the first water tank flows to the second water tank through the first pipe under the action of gravity; a second pipe connecting the first water tank and the second water tank; and a drive pump disposed in the second pipe, the drive pump being used to drive the settled wastewater to flow from the second water tank to the first water tank through the second pipe.

[0006] In some embodiments, the second water tank has a cavity for containing the wastewater, the cavity including a receiving section and a sedimentation section that are interconnected, the receiving section being connected to the outlet end, the inner diameter of the receiving section remaining constant along the direction of gravity, and the inner diameter of the sedimentation section gradually decreasing along the direction of gravity.

[0007] In some embodiments, the first pipeline is provided with a regulating valve, which is used to regulate the flow rate of the wastewater in the first pipeline.

[0008] In some embodiments, the first pipe is provided with a filter for filtering impurities in the wastewater.

[0009] In some embodiments, the wastewater treatment device includes a plurality of processing devices, a plurality of first water tanks are arranged at intervals, each first water tank is used to receive the wastewater generated by each of the processing devices, and a plurality of second water tanks are arranged at intervals, each second water tank corresponding to each of the first water tanks.

[0010] In some embodiments, the wastewater treatment device further includes an inlet pipe and an outlet pipe. The two ends of the inlet pipe are respectively connected to the processing equipment and the first water tank, and the two ends of the outlet pipe are respectively connected to the first water tank and the processing equipment. The wastewater generated by the processing equipment flows to the first water tank through the inlet pipe, and the wastewater after sedimentation in the second water tank flows to the processing equipment through the outlet pipe.

[0011] In some embodiments, the second water tanks are arranged at intervals along a vertical direction.

[0012] In some embodiments, the wastewater treatment device further includes a third pipe for connecting two adjacent second water tanks, wherein the solid particles deposited in the upper second water tank are discharged through the third pipe to the lower second water tank.

[0013] In some embodiments, the third pipeline is provided with a switching valve for controlling the on / off state of the third pipeline.

[0014] Secondly, a glass production line is provided, which includes the aforementioned wastewater treatment device.

[0015] The wastewater treatment device provided in this application involves wastewater in a first tank flowing through a first pipe to a second tank for sedimentation. After sedimentation, a pump drives the supernatant from the sedimentation in the second tank back to the first tank for further sedimentation. This cycle repeats, and through the cumulative effect of multiple sedimentations, the removal capacity for solid particles in the wastewater is greatly enhanced, thus improving the wastewater treatment device's purification capabilities. Furthermore, larger solid particles in the wastewater can undergo initial sedimentation in the first tank. Since the inlet height of the first pipe is greater than the outlet height, the wastewater in the first tank can naturally flow to the second tank under gravity, eliminating the need for an additional pump. This not only reduces energy consumption but also allows the wastewater to flow into the second tank at a gentle speed, minimizing disturbance to the sedimentation area and further enhancing the purification effect.

[0023] Please see Figures 1 to 4This application provides a wastewater treatment device, comprising a first water tank 10 for storing wastewater; a second water tank 20 for settling solid particles in the wastewater; a first pipe 30 having an inlet end 31 connecting the first water tank 10 and an outlet end 32 connecting the second water tank 20, the height of the inlet end 31 being greater than the height of the outlet end 32, the wastewater in the first water tank 10 flowing to the second water tank 20 under the action of gravity through the first pipe 30; a second pipe 40 connecting the first water tank 10 and the second water tank 20; and a drive pump 50 disposed in the second pipe 40, the drive pump 50 being used to drive the settled wastewater from the second water tank 20 to the first water tank 10 through the second pipe 40.

[0024] The wastewater treatment device of this application embodiment can be used to treat wastewater generated by glass drilling machines and edging machines. The first water tank 10 is a cubic or cylindrical container made of corrosion-resistant material, with a wastewater inlet at the top for connecting to the drain outlet of the glass drilling or edging machine to collect and store the original wastewater containing glass residue. The second water tank 20 is also made of corrosion-resistant material, and its overall volume may be slightly larger than that of the first water tank 10. The second water tank 20 is constructed as the main sedimentation zone, and its interior may optionally be equipped with inclined plates or the like to significantly increase the effective sedimentation area and accelerate the settling process of solid particles.

[0025] Both the first pipe 30 and the second pipe 40 refer to pipes used for transporting fluids, and can be pipes of various materials, such as rigid pipes (e.g., metal pipes) or flexible pipes. The first pipe 30 and the second pipe 40 are not limited to a single pipe body; they can include one or more pipe bodies, depending on the specific requirements. The first pipe 30 can be directly connected to the outlet of the first tank, or it can be indirectly connected to the outlet of the first tank through one or more other intermediate pipes. Similarly, the second pipe 40 can be directly connected to the outlet of the second tank, or it can be indirectly connected to the outlet of the second tank through one or more intermediate pipes. The drive pump 50 refers to a pump capable of providing driving force for the flow of fluid, such as a water pump, circulating pump, pneumatic pump, gear pump, peristaltic pump, etc., but not limited to these.

[0026] The wastewater treatment device of this embodiment operates as follows: Glass processing wastewater enters the first water tank 10 through the wastewater inlet. The first water tank 10 collects the wastewater, and some large glass particles in the water quickly settle to the bottom of the tank under their own gravity, completing primary sedimentation. The upper layer of wastewater in the first water tank 10 after primary sedimentation flows smoothly into the second water tank 20 through the first pipe 30 under gravity. In the stable environment of the second water tank 20, the wastewater is left to stand for a preset time, allowing the fine glass powder in the wastewater to slowly and fully settle to the bottom of the tank, achieving deep sedimentation and solid-liquid separation, and the water quality becomes clear. After sedimentation is completed, the drive pump 50 is started, and the clarified upper layer of liquid in the second water tank 20 is pumped back to the first water tank 10 through the second pipe 40. For extremely fine particles that cannot be removed in one sedimentation, they have multiple sedimentation opportunities as the sedimentation process is repeated, thus being effectively removed. This cyclic treatment mode greatly improves the removal rate of overall solid particles and achieves deep purification of water quality.

[0027] The wastewater treatment device provided in this application allows wastewater in the first water tank 10 to flow through the first pipe 30 to the second water tank 20 for sedimentation. After sedimentation, the driving pump 50 drives the supernatant after sedimentation in the second water tank 20 back to the first water tank 10 for further sedimentation. This cycle repeats, and through the cumulative effect of multiple sedimentations, the removal capacity of solid particles in the wastewater is greatly enhanced, which is beneficial to improving the purification capacity of the wastewater treatment device. In addition, larger solid particles in the wastewater can undergo preliminary sedimentation in the first water tank 10, and the height of the inlet end 31 of the first pipe 30 is greater than that of the outlet end 32. The wastewater in the first water tank 10 can flow naturally to the second water tank 20 under the action of gravity, so there is no need to install an additional water pump. This not only reduces energy consumption but also allows the wastewater to flow into the second water tank 20 at a gentle speed, thereby reducing disturbance to the sedimentation area of ​​the second water tank 20 and affecting the settling of solid particles, further enhancing the purification effect of the wastewater.

[0028] In some embodiments, the second water tank 20 has a cavity 21 for containing wastewater. The cavity 21 includes a receiving section 211 and a sedimentation section 212 that are interconnected. The receiving section 211 is connected to the outlet end 32. The inner diameter of the receiving section 211 remains constant along the direction of gravity, while the inner diameter of the sedimentation section 212 gradually decreases along the direction of gravity. Understandably, the constant inner diameter of the receiving section 211 forms a stable transition region, effectively receiving the water flowing in from the first pipe 30 and rapidly dissipating its remaining kinetic energy. This avoids the incoming water directly impacting the sedimentation area below, creating a stable environment for the settling of solid particles. The cone-shaped design of the sedimentation section 212, whose inner diameter gradually decreases along the direction of gravity, forms an efficient sludge guiding channel. This structure allows the settled solid particles to slide naturally towards the central area, preventing them from accumulating in the flat bottom area. After settling in the wide receiving section 211, the solid particles will quickly enter the guiding section and be concentrated, avoiding repeated suspension in the sedimentation zone, thus making the sedimentation efficiency higher and achieving better sedimentation effect in a smaller total volume.

[0029] In some embodiments, a regulating valve 61 is provided on the first pipe 30 to regulate the flow rate of wastewater in the first pipe 30. Understandably, the sedimentation efficiency of the second water tank 20 is limited. An excessively fast influent flow rate will shorten the actual residence time of the wastewater in the sedimentation zone, causing particles to be carried out before settling, affecting the effluent quality. By setting the regulating valve 61, the flow rate into the second water tank 20 can be precisely adjusted according to factors such as the actual sedimentation effect of the second water tank 20 or the concentration of solid particles in the wastewater, ensuring that the influent flow rate always matches the optimal treatment capacity of the second water tank 20. Furthermore, the throttling effect of the regulating valve 61 can control the water flow velocity within an extremely gentle range, ensuring a stable environment for the sedimentation process, which is conducive to the settling of solid particles, thereby further enhancing the sedimentation effect. Optionally, the regulating valve 61 can be a gate valve, globe valve, butterfly valve, or electrically operated regulating valve 61, etc.

[0030] In some embodiments, the first pipe 30 is equipped with a filter 62, which is used to filter impurities in the wastewater. Understandably, the filter 62 has a filter screen or filter element with a certain pore size, allowing water to flow through while trapping solid particles larger than the pore size on the surface of the filter screen or in the collection chamber inside. As a physical barrier, the filter 62 can effectively trap large particles or light floating matter carried in the wastewater, such as plastic fragments, sealant residue, or larger organic impurities. If these impurities enter the second water tank 20, they will not only be difficult to settle themselves, but will also disrupt the overall stability of the water body, and may even float to the surface to form scum, seriously affecting the quality of the final effluent. Furthermore, filtration can prevent pipe and valve blockage, ensure stable system operation, greatly reduce system failure rate and maintenance frequency, and guarantee the continuity and stability of the gravity flow process.

[0031] In some embodiments, the wastewater treatment device includes multiple processing devices 70, multiple first water tanks 10 arranged at intervals, each first water tank 10 being used to receive wastewater generated by each processing device 70, and multiple second water tanks 20 arranged at intervals, each second water tank 20 corresponding to each first water tank 10. Specifically, the processing device 70 is an edge grinding machine or a drilling machine. The wastewater generated by the edge grinding machine or drilling machine may have different particle size distributions and concentrations of glass powder. If all the wastewater is mixed for treatment, the differences in water quality may lead to unstable recycled water quality. However, by connecting each first water tank 10 to each processing device 70, it is ensured that the recycled water obtained by each device is relatively stable and controllable, avoiding the unpredictability caused by the mixing of wastewater from different devices, and helping to ensure the quality of high-precision processing.

[0032] In some embodiments, the wastewater treatment device further includes an inlet pipe 81 and an outlet pipe 82. The two ends of the inlet pipe 81 are respectively connected to the processing equipment 70 and the first water tank 10, and the two ends of the outlet pipe 82 are respectively connected to the first water tank 10 and the processing equipment 70. The wastewater generated by the processing equipment 70 flows to the first water tank 10 through the inlet pipe 81, and the wastewater after sedimentation in the second water tank 20 flows to the processing equipment 70 through the outlet pipe 82.

[0033] Wastewater from processing equipment 70 is collected in the first water tank 10 via inlet pipe 81. After system sedimentation and purification, the clean recycled water is returned to processing equipment 70 for reuse via outlet pipe 82. This allows the entire glass processing process to operate almost entirely without external continuous water supply and without discharging wastewater into the environment, achieving internal recycling and reuse of production water resources and maximizing water-saving and environmental benefits. Furthermore, inlet pipe 81 ensures that wastewater generated by processing equipment 70 can be discharged promptly and directionally, preventing wastewater from overflowing around the equipment and maintaining a clean workshop environment. Outlet pipe 82 establishes a stable and reliable dedicated water supply line for processing equipment 70, ensuring a continuous supply of recycled water and eliminating the risk of production stoppage due to external water supply interruptions or unstable water pressure, thus guaranteeing the continuity and stability of production.

[0034] In some embodiments, the second water tanks 20 are arranged at intervals in the vertical direction. Since the cost of floor space in industrial plants is high and fixed, by arranging multiple second water tanks 20 at intervals in the vertical direction, the water treatment system that originally required a huge floor area can be compressed into a smaller footprint, thereby making reasonable use of vertical space and improving space utilization.

[0035] In some embodiments, the wastewater treatment apparatus further includes a third pipe 83 for connecting two adjacent second water tanks 20. In any two adjacent second water tanks 20, solid particles deposited in the upper second water tank 20 are discharged through the third pipe 83 to the lower second water tank 20.

[0036] Understandably, the upper second water tank 20 can be configured to have a smaller volume, while the lower second water tank 20 can be configured to have a larger volume. Each of the upper second water tanks 20 can be periodically emptied according to a preset program, quickly discharging accumulated sediment into the lower second water tank 20 through the third pipe 83. This avoids excessive sediment buildup in each smaller second water tank 20, which would affect the sedimentation effect, and the operation is regular and simple. The larger lower second water tank 20 can centrally collect sediment and has sufficient volume to receive multiple empties from the upper second water tanks 20. This eliminates the need for frequent processing of each upper unit; operators only need to periodically perform a thorough sludge removal from the larger lower second water tank 20, effectively improving the convenience of maintenance.

[0037] In some embodiments, the third pipe 83 is equipped with a switch valve 63, which controls the opening and closing of the third pipe 83. By setting the switch valve 63, the system is allowed to sequentially and one by one open the third pipes 83 between adjacent second water tanks 20 according to a preset program. The valve between a specific upper second water tank 20 and a lower second water tank 20 is only opened when sewage discharge is required, and is closed immediately after sludge discharge is completed. If all third pipes 83 are constantly open, the thinner sediment in the upper layer will continuously interfere with the sediment in the lower layer that is being concentrated, destroying the sedimentation effect. The on / off control ensures that the sewage discharge operation of each second water tank 20 is carried out independently and orderly, maintaining the stability and effectiveness of the entire sedimentation process.

[0038] This application also proposes a glass production line, which includes a wastewater treatment device. The specific structure of the wastewater treatment device is as described in the above embodiments. Since this automotive glass sealing strip production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0039] In summary, the wastewater treatment device provided in this application allows wastewater in the first tank 10 to flow through the first pipe 30 to the second tank 20 for sedimentation. After sedimentation, the driving pump 50 drives the supernatant after sedimentation in the second tank 20 back to the first tank 10 for further sedimentation. This cycle, through the cumulative effect of multiple sedimentations, greatly enhances the removal capacity of solid particles in the wastewater, thus improving the wastewater treatment device's purification capacity. Furthermore, larger solid particles in the wastewater can undergo initial sedimentation in the first tank 10. Since the height of the inlet end 31 of the first pipe 30 is greater than the outlet end 32, the wastewater in the first tank 10 can naturally flow to the second tank 20 under gravity. Therefore, no additional water pump is required, which not only reduces energy consumption but also allows the wastewater to flow into the second tank 20 at a gentle speed, reducing disturbance to the sedimentation area of ​​the second tank 20 and thus affecting the settling of solid particles, further enhancing the wastewater purification effect.

[0040] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
