[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] First, as Figure 1As shown, in some exemplary embodiments of the present application, a wastewater recovery and treatment mechanism for treating glass grinding wastewater is provided, which mainly includes an aeration component 10, a filtration component 20, a particle treatment component 30 and a water treatment component 40. The aeration component 10 includes an aeration tank 11, an aeration structure 12 and a liquid inlet 13. The output port of the aeration structure 12 is located in the aeration tank 11, and the liquid inlet 13 is connected to the aeration tank 11 for the introduction of glass grinding wastewater; the filtration component 20 includes a liquid inlet end 21, a liquid outlet end 22, a slag outlet end 23 and a first pump 24, and the first pump 24 is located between the liquid inlet end 21 and the aeration tank 11; the particle treatment component 30 is connected to the slag outlet end 23 for cleaning and drying glass particles; the water treatment component 40 is connected to the liquid outlet end 22 for water treatment of glass grinding wastewater.

[0030] The liquid outlet 22 and the residue outlet 23 of the filter assembly 20 can separate the liquid from the residue, and guide the liquid to the water treatment assembly 40 and the particle treatment assembly 30, respectively. The particle treatment assembly 30 and the water treatment assembly 40 then process the residue and the water, respectively, to obtain glass particles and recycled water, thereby achieving dual solid and liquid recovery and improving the effective recovery rate of glass grinding waste liquid. This application effectively solves the problem of poor treatment effect of glass grinding waste liquid and the inability to effectively recover glass particles in the prior art.

[0031] like Figure 1 As shown, in some exemplary embodiments of the present application, the aeration structure 12 includes an aeration pump 121 and an aeration pipeline 122. The aeration pipeline 122 is inserted into the aeration tank 11 and is provided with multiple air outlets. The aeration pump 121 is connected to an air source at one end remote from the aeration pipeline 122. The operation of the aeration pump 121 increases the dissolved oxygen content of the glass grinding wastewater in the aeration tank 11, thereby promoting the decomposition and conversion of organic matter and providing a stirring and mixing effect.

[0032] It should be noted that the aeration pipeline 122 is inserted from the side of the aeration tank 11 close to the bottom, and the position after insertion is also close to the bottom of the aeration tank 11. This arrangement allows the gas to stir the bottom of the aeration tank 11 during aeration, and impurities will move with the movement of the airflow, thereby preventing impurities such as glass particles from being deposited at the bottom of the aeration tank 11 and affecting subsequent treatment.

[0033] like Figure 1 As shown, in some exemplary embodiments of the present application, the water treatment component 40 includes a blending tank 41, a filtration tank 42 and an output pipeline 43 connected in sequence, and the output pipeline 43 includes a recovery branch line 431 and a liquid supply branch line 432, and the liquid supply branch line 432 is connected to the particle treatment component 30.

[0034] The blending tank 41 and filtration tank 42 are used to blend and filter water, cleaning and restoring it for reuse. A recovery branch line 431 connects to the workshop's glass grinding equipment or its water supply system, facilitating direct glass grinding. A liquid supply branch line 432 provides cleaning water for the particle processing assembly 30, further cleaning and separating particulate matter within the assembly, leaving relatively pure glass particles for easy recycling.

[0035] It should be noted that in order to facilitate the control of the supply and demand relationship between the recovery branch line 431 and the liquid supply branch line 432, the recovery branch line 431 can be connected to the liquid storage tank to facilitate the collection of the recovered liquid. A second valve 433 is provided on the recovery branch line 431, and a third valve 434 is provided on the corresponding liquid supply branch line 432 for controlling the on and off of the liquid supply branch line 432.

[0036] When the wastewater recycling and treatment mechanism is in operation, the third valve 434 on the liquid supply branch line 432 is preferentially opened to fully utilize the recovered liquid to supply water to the particle processing assembly 30. It is understood that to ensure stable liquid pressure, a liquid storage tank is provided within the particle processing assembly 30, and the corresponding third valve 434 is configured as a safety valve. As the amount of recovered liquid stored in the liquid storage tank gradually increases, the pressure at the end of the safety valve closest to the liquid storage tank increases, automatically closing the third valve 434 to protect the liquid storage tank and the particle processing assembly 30.

[0037] Furthermore, the second valve 433 can be configured as a relief valve. When the third valve 434 is closed, the fluid pressure on the recovery branch line 431 gradually increases, thereby achieving the purpose of opening the relief valve, allowing the recovered liquid to flow to the outside through the relief valve.

[0038] In some optional embodiments, the second valve 433 and the third valve 434 can be configured as solenoid valves, and the valves can be opened and closed in coordination with each other through a control component.

[0039] In some optional embodiments, fluid flow meters and fluid pressure gauges can be installed on both the recovery branch line 431 and the liquid supply branch line 432 to facilitate the observation of the fluid pressure in the pipeline at any time to avoid excessive or insufficient pressure that affects other processes.

[0040] In some exemplary embodiments of the present application (not shown in the figure), the mixing tank 41 is provided with an automatic dosing device. The mixing tank 41 is provided to adjust the internal components of the initially separated recovery liquid so that its physical and chemical properties can meet the grinding and cleaning effects.

[0041] The automatic dosing device can specifically include a pH detection structure, a water adding structure, a dosing structure and a stirring structure. The pH detection structure is used to measure the pH value of the recovered liquid to facilitate the dosing structure to control the amount of dosing. The water adding structure can adjust the overall viscosity and fluidity of the recovered liquid. The stirring structure can fully stir the recovered liquid to make the water body more uniform after adding medicine or water, which is convenient for stabilizing the detection results.

[0042] A connecting line 44 and a fourth valve 45 are provided between the blending tank 41 and the filtration tank 42. The connecting line 44 connects the two, and the fourth valve 45 is configured to control the opening and closing of the connecting line 44, thereby facilitating sufficient blending in the blending tank 41. The fourth valve 45 can be configured as a solenoid valve, which is opened and closed by a control component to coordinate the blending tank 41 and the filtration tank 42 in different processes.

[0043] In some exemplary embodiments of the present application (not shown in the figure), a reverse osmosis device is provided in the filter tank 42. The reverse osmosis device is used to perform osmotic filtration on the prepared liquid to further remove dissolved salts and organic matter in the recovered liquid, thereby improving the quality of the recovered liquid.

[0044] The reverse osmosis device may specifically be a reverse osmosis membrane disposed in the filter pool 42 . The reverse osmosis membrane divides the filter pool 42 into two spaces. The first space is connected to the connecting pipeline 44 , and the second space is connected to the output pipeline 43 .

[0045] like Figure 1 As shown, in some exemplary embodiments of the present application, the particle processing assembly 30 includes a cleaning structure 31, a drying structure 32, and a conveyor belt 33. The conveyor belt 33 is disposed between the cleaning structure 31 and the drying structure 32, and the liquid supply branch line 432 is connected to the cleaning structure 31. The cleaning structure 31 is used to wash away impurities such as dust adhering to the glass particles, and at the same time, screen out glass particles above a certain size to ensure that the physical and chemical properties of the glass particles are consistent during subsequent use.

[0046] The cleaning structure 31 may specifically be a spray head, which sprays water mist or fluid with a certain pressure like glass particles to remove light impurities.

[0047] The conveyor belt 33 is used to transport the glass particles and send them to the drying structure 32 to remove moisture and form dry glass particles for subsequent transportation and use. The drying structure 32 can be an electric heater for releasing heat to dry the moisture.

[0048] A recycler 35 is provided at the output port of the drying structure 32 to collect the dried glass particles for subsequent packaging and transportation. The recycler 35 can be a cullet hopper that can carry and transport the glass particles.

[0049] like Figure 1 As shown, in some exemplary embodiments of the present application, the cleaning structure 31 includes a water collection tank 311, a second pump 312, and a recovery pipeline 313. The recovery pipeline 313 is connected to the water collection tank 311 and the aeration tank 11 respectively, and the second pump 312 is located on the recovery pipeline 313. The water collection tank 311, the second pump 312, and the recovery pipeline 313 are configured to collect and recycle the wastewater used to clean the glass particles and transport it back to the aeration tank. This configuration allows the cleaning water to be treated multiple times. On the one hand, it can avoid direct waste of the recovered liquid. On the other hand, the particulate matter content in the cleaning water is lower than that in the glass grinding wastewater. When added to the aeration tank 11, it can mix with the glass grinding wastewater, reducing the percentage of particulate matter and increasing its fluidity, making it easier for it to enter the filter assembly 20.

[0050] like Figure 1 As shown, in some exemplary embodiments of the present application, the recovery line 313 is connected to the side of the aeration tank 11 away from the bottom of the tank, and its vertical height is higher than the height of the liquid inlet 13. Such a setting can increase the falling height of the recovered liquid in the recovery line 313, play the effect of dispersing the glass grinding wastewater, disrupt the stability of the water body, and facilitate uniform mixing.

[0051] like Figure 1 As shown, in some exemplary embodiments of the present application, a screw conveyor 34 is provided between the cleaning structure 31 and the slag discharge end 23. The provision of the screw conveyor 34 facilitates the transfer of waste slag with a high solid content, and the delivery is achieved through the internal spiral blades.

[0052] The screw conveyor 34 is controlled by a separate motor to maintain continuous rotation and avoid the occurrence of agglomeration of particles.

[0053] like Figure 1 As shown, in some exemplary embodiments of the present application, the filtration assembly 20 includes a dual-selection integrated machine 25, with at least two slag discharge ends 23 located on the dual-selection integrated machine 25, and a screw conveyor 34 with corresponding slag discharge openings corresponding to the slag discharge ends 23. The dual-selection integrated machine allows the glass grinding wastewater to settle to the bottom under the action of gravity, facilitating the discharge of the waste residue. The dual-selection integrated machine is specifically an SS dual-selection integrated machine, which has an internal power mechanism that can drive a scraper within the trough to scrape the bottom sediment and transport it to the slag discharge end 23.

[0054] Furthermore, if Figure 1As shown, in some exemplary embodiments of the present application, the slag discharge end 23 is connected to a discharge pipeline 26, which is provided with a first valve 27. The slag discharge end 23 is provided at the bottom of the trough of the SS dual-selection machine, and the glass particles settled at the bottom are discharged through the first valve 27 and the discharge pipeline 26.

[0055] It is understandable that under the action of the SS dual-selection machine, the glass particles deposited at the bottom will gradually increase. At this time, the first valve 27 is opened, and under the action of gravity, the glass particles mixed with a small amount of waste liquid are discharged downward under the action of the scraper and enter the screw conveyor 34. The screw conveyor 34 then discharges the waste residue through its downward-opening drop port 341, and the waste residue enters the cleaning structure 31 through the residue collecting pipe 314.

[0056] The size of the slag discharge end 23 gradually decreases as it approaches the screw conveyor 34, so that a slope is formed on the side wall of the pipe, so that the waste slag adhering to the side wall will be affected by gravity, increasing the force of sliding downward, making it easier to discharge.

[0057] It should be noted that the discharge port 341 of the screw conveyor 34 is smaller than the opening of the slag collecting pipe 314, and the slag collecting pipe 314 gradually decreases in the direction away from the opening, which makes it easier for the waste slag to be concentrated in the cleaning structure 31, which is beneficial to the cleaning effect.

[0058] In one embodiment, the operation process of the wastewater recycling and treatment mechanism is as follows:

[0059] The glass grinding wastewater in the workshop is introduced into the aeration tank 11, and the aeration structure 12 is opened to increase the dissolved oxygen content of the glass grinding wastewater. The first pump 24 is turned on to send the glass grinding wastewater into the dual-selection machine for sedimentation of the glass grinding wastewater. During the sedimentation process, the upper clear liquid is transported to the water treatment component 40 for mixing and reverse osmosis filtration to produce recovered liquid. At this time, the third valve 434 is opened, the second valve 433 is closed, and the recovered liquid is sent to the workshop for storage.

[0060] When the waste glass accumulates in the trough of the dual-selection machine, and when the waste glass accumulates to a certain amount, the third valve 434 is closed, and the second valve 433 and the first valve 27 are opened to simultaneously feed the recovery liquid and the waste glass into the cleaning structure 31 to clean the glass particles.

[0061] After cleaning is completed, the cleaning wastewater is collected by the sump 311 and re-introduced into the aeration tank 11 through the second pump 312 and the recovery pipeline 313, while the glass particles are conveyed into the drying structure 32 by the conveyor belt 33 for drying and finally discharged into the recycler 35 to realize the recovery of the glass particles and can be transported to the batching workshop for recycling.

[0062] Secondly, in some exemplary embodiments of the present application, a wastewater treatment apparatus is provided, which primarily includes a control component and a wastewater recovery and treatment mechanism as described in any of the aforementioned embodiments. The control component is electrically connected to the aeration structure 12, the first pump 24, the particle treatment component 30, and the water treatment component 40. The beneficial effects of the wastewater recovery and treatment mechanism are described in the aforementioned embodiments and are not further elaborated here. The control component is configured to automate the wastewater recovery and treatment mechanism, enabling real-time monitoring of its operation, thereby reducing manual intervention and improving wastewater treatment efficiency.

[0063] In an optional embodiment, the aeration pump of the aeration structure 12, the fifth valve 221 on the liquid outlet 22, the first pump 24, the dual-selection machine 25, the first valve 27, the cleaning structure 31, the second pump 312, the drying structure 32, the conveyor belt 33, the screw conveyor 34, the water treatment component 40, the second valve 433, the third valve 434, and the fourth valve 45 are all electrically connected to the control component, so that the treatment process of the glass grinding wastewater can be controlled.

Those skilled in the art will understand that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present application.
