[0018] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0020] Example 1: This embodiment provides a wastewater treatment system for microcrystalline glass edging, including: Wastewater pond 1 is used to store wastewater discharged during production. The flocculation device includes a reagent dosing mechanism 2 and a wastewater mixing and reaction mechanism 3. The reagent dosing mechanism 2 is used to add reaction reagents to the wastewater mixing and reaction mechanism 3, and the wastewater mixing and reaction mechanism 3 is used to coagulate wastewater and reaction reagents to form sludge. Purification device 4 is connected to flocculation device and is used to separate sludge and clean water; Sludge collection tank 5 is connected to purification device 4 and is used to collect and store sludge discharged from purification device 4. The clean water collection tank 6 is connected to the purification device 4 and is used to collect and store the clean water discharged from the purification device 4. The filter press 7 is connected to the sludge collection tank 5 and is used to press the sludge in the sludge collection tank 5.

[0021] In this technical solution, a water pump is installed in the wastewater tank 1. The workshop grinding wastewater in the wastewater tank 1 is pumped to the wastewater mixing and reaction mechanism 3. The reagent dosing mechanism 2 delivers the reaction reagents for wastewater flocculation into the wastewater reaction mechanism. The reagent delivery mechanism is a commercially available product and will not be described in detail. The reagent delivery mechanism adds sodium hydroxide and polyaluminum chloride to the wastewater reaction mechanism in a measured amount using a mechanical diaphragm pump. The wastewater and reagents undergo sufficient reaction, flocculation, and coagulation to form a mixed liquid of clear water and sludge. The liquid then enters the purification device 4, which separates the clear water and sludge. The clear water is discharged into the clear water collection tank 6 for recycling, while the sludge is discharged into the sludge collection tank 5 and then pumped by a diaphragm pump to the filter press 7 for processing. Furthermore, the filter press 7 can be a plate and frame filter press, which can be purchased from the market. The plate and frame filter press is used to press the sludge, and the pressed water is recycled to the clean water collection tank 6. The pressed solid cake can be collected directly as ordinary solid waste and discharged centrally.

[0022] In summary, this microcrystalline glass edging wastewater treatment system first uses a wastewater mixing and reaction mechanism 3 to mix and react wastewater and reagents. Then, the reacted liquid is sent to a purification device 4 for separation, separating the sludge and clean water produced in the reaction. The clean water is recycled, while the sludge is further filtered using a filter press 7. The filtered water is also recycled, and the resulting sludge cake is discharged centrally. This system achieves rapid and efficient wastewater purification, and the purified water can be recycled, solving environmental pollution problems and saving a significant amount of water resources, thereby greatly reducing the company's production costs.

[0023] Example 2: This embodiment provides a microcrystalline glass edging wastewater treatment system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0024] Furthermore, the wastewater mixing and reaction mechanism 3 includes: The feeding pipeline includes a mixing pipe 31 and two feed pipes 32. The mixing pipe 31 is connected to the wastewater tank 1, and the two ends of the feed pipes 32 are respectively connected to the mixing pipe 31 and the reagent dispensing mechanism 2. A stirring assembly is provided on the mixing tube 31 and is used to stir the fluid inside the mixing tube 31. The reaction mixing tank 33 is connected to the mixing pipe 31 and is used to collect and store the mixed liquid of wastewater and reaction reagents.

[0025] Furthermore, the mixing pipe 31 includes a first pipe body 311 and a second pipe body 312 connected in sequence, and two feed pipes 32 are respectively connected to the first pipe body 311 and the second pipe body 312.

[0026] In this technical solution, the mixing pipe 31 includes a first pipe body 311 and a second pipe body 312 connected in sequence. The first pipe body 311 is corrugated and connected to the water pump in the wastewater tank 1. The second pipe body 312 is connected to the tail of the first pipe body 311. One feed pipe 32 is connected to the head of the first pipe body 311, and the other feed pipe 32 is connected to the tail of the first pipe body 311. The reagent dosing mechanism 2 first delivers the reagent into the first pipe body 311 through one feed pipe 32. Then, the reagent and wastewater flow and mix in the first pipe body 311. Then, the reagent dosing mechanism 2 delivers the second reagent to the tail of the first pipe body 311 through the other feed pipe 32. After the wastewater is mixed with the first reagent, it flows into the second pipe 312. At the tail end of the first pipe 311, it mixes with the second reagent and then flows into the reaction mixing tank 33 for a complete reaction. The reaction mixing tank 33 is equipped with stirring beads. When the wastewater and reagent flow into the tank, they impact the stirring beads, causing them to tumble and agitate the mixture, thus achieving the mixing reaction of the wastewater and reagent. A stirring assembly is installed at the connection between the first pipe 311 and the second pipe 312. This assembly stirs and premixes the wastewater containing the reagent, ensuring a thorough reaction between the reagent and the wastewater, reducing reagent consumption, accelerating the mixing reaction, lowering production costs, and improving work efficiency.

[0027] Example 3: This embodiment provides a microcrystalline glass edging wastewater treatment system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0028] Furthermore, the stirring assembly includes: The housing 34 is pipe-shaped and is disposed between the first pipe body 311 and the second pipe body 312; Transmission module 35, which is disposed within housing 34; The first stirring paddle 36 is disposed inside the first tube 311 and connected to the transmission module 35. The drive motor is located outside the housing 34 and is used to drive the transmission module 35 to work.

[0029] In this technical solution, a U-shaped connecting pipe 313 is provided for connecting the first pipe body 311 and the second pipe body 312. The two ends of the U-shaped connecting pipe 313 are respectively connected to the periphery of the first pipe body 311 and the periphery of the second pipe body 312. The housing 34 of the stirring assembly is pipe-shaped and is connected between the ends of the first pipe body 311 and the second pipe body 312 by fasteners, which enhances structural consistency and ensures the structural stability and aesthetics of the pipeline. The transmission module 35 consists of a rotating rod and a gear set. One end of the rotating rod is connected to the output end of the drive motor outside the housing 34 through a coupling, and the other end is connected to the gear set. The gear set can be a worm gear assembly or two bevel gears. The handle of the first stirring paddle 36 is connected to the gear set. By controlling the operation of the gear set with the drive motor, the first stirring paddle 36 is driven to rotate, thereby stirring and mixing the liquid flowing out of the first pipe body 311 and another agent, thereby accelerating the mixing efficiency and improving the wastewater treatment efficiency.

[0030] Furthermore, the stirring assembly also includes a second stirring paddle 37, which is disposed within the second pipe body 312 and connected to the transmission module 35. The gear set of the transmission module 35 consists of a driving bevel gear and two driven bevel gears meshing with the driving bevel gear. The two driven bevel gears are arranged opposite each other and are respectively connected to the first stirring paddle 36 and the second stirring paddle. The driving bevel gear is controlled to rotate by a drive motor, which drives the two driven bevel gears to rotate, thereby achieving synchronous rotation of the first stirring paddle 36 and the second stirring paddle 37 to stir the liquid. This allows the liquid to be stirred once when it flows out of the first pipe body 311 and mixes with another agent, and then the mixed liquid is stirred a second time when it flows into the second pipe body 312 through the connecting pipe. The two stirrings accelerate the mixing of wastewater and the agent, improving wastewater treatment efficiency.

[0031] Example 4: This embodiment provides a microcrystalline glass edging wastewater treatment system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0032] Furthermore, the water purification device includes: Tank body 41, which includes a top cover 411, a cylindrical part 412 and an inverted conical part 413 connected in sequence; A vortex separator 43 is disposed inside the cylindrical portion 412; Liquid inlet pipe 44, one end of which is connected to cylindrical part 412, and the other end of which is connected to reaction mixing tank 33; The outlet pipe 45 is connected at both ends to the top cover 411 and the clean water collection tank 6, respectively, for discharging clean water. The sewage pipe 46 is connected at both ends to the inverted cone part 413 and the sludge collection tank 5, respectively, for discharging sludge.

[0033] In this technical solution, a bowl-shaped swirl separator 43 is installed inside the tank 41. The periphery of the swirl separator 43 is connected to the inner wall of the tank 41 by several integrally formed connecting plates, forming a material passage between adjacent connecting plates. One end of the inlet pipe 44 is tangentially connected to the cylindrical part 412 of the pipe body and faces the swirl separator 43, while the other end is tangentially connected to the reaction mixing tank 33. The wastewater mixture flows through the inlet pipe 44 onto the swirl separator 43 and flows along the inner wall of the swirl separator 43. The wastewater mixture with a certain flow velocity enters the tank 41 and, after being guided by the swirl separator 43, generates a swirling flow within the tank 41. The centrifugal force generated by the swirling flow aggregates the flocculants and suspended particles in the wastewater mixture to form sludge, which is then thrown towards the inner wall of the tank 41. The aggregated sludge, due to its higher density, sinks, while the clear water in the wastewater mixture rises. As the wastewater mixture is continuously fed in, the clean water rises. After reaching the top cover 411, the clean water is discharged through the outlet pipe 45 into the clean water collection tank 6 for storage. The sludge settles and accumulates in the inverted cone 413, and is then periodically discharged through the sewage pipe 46 into the sludge collection tank 5 for storage, thus achieving the separation and discharge of sludge and clean water in the wastewater mixture.

[0034] In addition, some of the precipitated sludge may fall onto the cyclone separator plate 43, while the wastewater mixture that is subsequently flushed onto the cyclone separator plate 43 from the inlet pipe 44 can flush out the sludge that has fallen onto the cyclone separator plate 43 and let it fall into the inverted cone part 413, thus preventing the sludge from accumulating on the cyclone separator plate 43 and not being completely discharged.

[0035] Example 5: This embodiment provides a microcrystalline glass edging wastewater treatment system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0036] Furthermore, the wastewater mixing and reaction mechanism 3 includes: The reflux line 38 is connected to the reaction mixing tank 33.

[0037] In this technical solution, both the reaction mixing tank 33 and the inlet pipe 44 are connected to the return pipe 38. The liquid that has not fully reacted in the reaction mixing tank 33 can be sent back to the wastewater pool 1 through the return pipe 38. The clean water that cannot be discharged from the outlet pipe 45 in the tank 41 and some of the wastewater mixture that has not been completely purified can also return to the reaction mixing tank 33 through the inlet pipe 44, which has a certain cleaning effect on the inner wall of the reaction mixing tank 33. Then, it is sent back to the wastewater pool 1 through the return pipe 38 for subsequent purification treatment.

[0038] It is worth noting that the reflux line 38 includes a first branch and a second branch. The first branch and the second branch are respectively connected to the bottom and top of the reaction mixing tank 33. The liquid reflux preferentially flows into the reflux line 38 from the first branch. If the bottom of the reaction mixing tank 33 is blocked, it flows into the reflux line 38 from the top of the second branch.

[0039] Furthermore, the water purification device also includes: The first cleaning pipe 42 is connected to the top cover 411 and the clean water collection tank 6 respectively. The second cleaning pipe 47 is connected to the cylindrical part 412 and the first cleaning pipe 42 respectively. The first cleaning pipe 42 and the second cleaning pipe 47 are both used to clean the inside of the tank 41.

[0040] This structural design allows a water pump to transport clean water from the clean water collection tank 6 through the first cleaning pipe 42 from the top of the tank 41 into the tank 41, cleaning the inside of the tank 41. Clean water output from the clean water collection tank 6 can also be used to clean the inner wall of the tank 41 through the second cleaning pipe 47, washing away the sludge adhering to the inner wall of the tank 41, thus effectively cleaning the tank 41. It is worth noting that the number of second cleaning pipes 47 can be set according to actual needs to ensure a good cleaning effect on the inner wall of the tank 41.

[0041] Example 6: This embodiment provides a method for using a microcrystalline glass edging wastewater treatment system, including the following steps: S1. Wastewater in wastewater tank 1 and reaction reagents in reagent dosing device 2 are transported together into wastewater mixing reaction device 3 for coagulation to form sludge mixture; S2. The sludge mixture is fed into the purification device 4, where the sludge and clean water are separated. S3. The upper layer of clean water in the purification device 4 is discharged into the clean water collection tank 6, and the lower layer of sludge in the purification device 4 is discharged into the sludge collection tank 5. S4. The sludge in the sludge collection tank 5 is then transported to the filter press 7, where the remaining water in the sludge is squeezed out.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
