Description

TECHNICAL FIELD

[0002] Ceramics are widely used in the fields of building materials, daily-use ceramics, industrial ceramics, etc. During the production process, industrial wastewater containing a large amount of solid impurities and suspended pollutants is generated. If the wastewater is directly discharged, the ecological environment such as water bodies and soil will be seriously polluted, and relevant environmental protection regulations may be violated. Meanwhile, the wastewater resources are not reasonably recycled and utilized, resulting in resource waste. Therefore, it is an important requirement to meet environmental protection requirements and improve resource utilization rate to develop an industrial wastewater treatment device for ceramic production, which is efficient in filtration, accurate in purification and convenient in operation.

Pressure rollers 13 are rotatably connected to the lower ends of the front and rear guide plates 12, and the pressure rollers 13 abut against the top surface of the grid plate 11.

[0019] Example 3: The technical solution is basically the same as that of Example 1, except that, as Figure 6 , Figure 7 , Figure 8As shown, a circular filter screen 24 is vertically installed inside the second tank 3. A fixing frame 25 is installed on the outer side of the lower end of the circular filter screen 24. A lifting frame 26 is connected to the outer side of the fixing frame 25. The output shafts of electric actuators 27 are connected to the four ends of the bottom surface of the lifting frame 26. The electric actuators 27 are installed on the bottom surface of the base 4.

The aeration disc 28 facilitates the generation of aeration effect, promotes the decomposition of pollutants, and accelerates the sedimentation of impurities.

[0020] Working principle: In this embodiment, the present invention also proposes a method for using an industrial wastewater treatment device for ceramic production, including the following steps: Step 1: Before starting the wastewater treatment operation, connect all electrical equipment to the power supply and ensure that all components and mechanisms are in normal working order. After preparation, the industrial wastewater generated during ceramic production flows slowly and steadily into the first tank 1 through the feed hopper 5 installed at the top inlet of the tank cover 2. The feed hopper 5 effectively avoids splashing and uneven feeding of wastewater, ensuring that the wastewater enters the filtration stage at a uniform speed. At the same time, the trapezoidal guide plates 12 installed at the front and rear ends of the top of the first tank 1 collect and guide the flowing wastewater, ensuring that all wastewater can flow through the upper grid plate 11 for filtration, preventing wastewater from leaking out and flowing directly into the second tank 3 without filtration. In addition, the pressure rollers 13 rotatably connected to the lower sides of the guide plates 12 at the front and rear ends are connected to the grid plate. The top surface of 11 abuts against each other, ensuring that the chain plate composed of multiple connecting plates 10 maintains a U-shaped state and preventing the transmission roller 7 from spinning idly and affecting the normal operation of the filter assembly. Then, the reduction motor 9 is started, and its output shaft drives the transmission roller 7 on the lower side to rotate through the coupling. Since the transmission roller 7 is longitudinally connected to the four corners inside the first tank 1, and the distance between the two upper transmission rollers 7 is greater than that between the two lower transmission rollers 7, when the transmission roller 7 rotates, it will drive the hexagonal turntable 8 installed at its front and rear ends to rotate synchronously. During the rotation of the hexagonal turntable 8, the connecting rod in its groove is driven to move. The connecting plate 10 that is movably hinged at the front and rear ends of the two adjacent connecting rods drives all the connecting rods to move synchronously, thereby making the grid plate 11 rotatably connected on the connecting rods operate in an orderly manner. When the wastewater flows through the grid plate 11, the larger impurities contained therein are effectively intercepted by the grid plate 11, completing the initial filtration of the wastewater. Step two: As the filtration process continues, the grid plate 11, with a large amount of larger impurities adsorbed on its surface, will move in a circular motion along the chain plate composed of connecting plates 10 until it reaches the cleaning tank 14 at the outlet on one side of the first tank 1. Because the width of the grid plate 11 is greater than the distance between two adjacent connecting rods, and the grid plate 11 is rotatably connected to the connecting rods, the grid plate 11 will naturally flip over as it enters the cleaning tank 14. At the moment of flipping, the front of the grid plate 11 collides with the inner wall of the cleaning tank 14, which can shake off some of the impurities attached to the surface, preparing for subsequent cleaning. At this time, the external water supply device is activated, and the cleaning water is stably delivered through the water pipe 16 installed above the cleaning tank 14. Multiple nozzles 1 are installed at the front end of the bottom of the water pipe 16. 7. The cleaning water is sprayed downwards in the form of a high-pressure water jet to thoroughly rinse the surface and back of the grating plate 11, completely washing away the impurities attached to the grating plate 11 and effectively preventing the grating plate 11 from clogging and affecting the filtration efficiency. The wastewater generated during the cleaning process, as well as the impurities that are washed away and shaken off, will flow into the drain pipe 15 installed at the drain outlet at the lower rear end of the cleaning tank 14, and finally be discharged from the cleaning tank 14 through the drain pipe 15, completing the cleaning of the grating plate 11. After cleaning, the grating plate 11 will continue to circulate with the chain plate and return to the filtration position in the first tank 1 to continue the wastewater filtration operation, realizing the recycling of the filtration components and ensuring the continuous and stable operation of the filtration operation. Step 3: After preliminary filtration and removal of larger impurities by the filter assembly inside the first tank 1, the wastewater will naturally flow into the second tank 3, which is connected to the bottom of the first tank 1. At this time, the sedimentation discharge mechanism inside the second tank 3 is activated to begin the deep treatment of the wastewater. In the sedimentation discharge mechanism, the support frame 18, which is horizontally installed on the upper part of the inner wall of the second tank 3, provides stable mounting support for the servo motor 19 with a protective shell installed in the middle of its top surface. After the servo motor 19 is started, its output shaft passes through the support frame 18 and drives the lower rotating part through the flange. Shaft 20 rotates; when shaft 20 rotates, it will synchronously drive the connecting frame 21, which is horizontally connected to its upper end via flange, to rotate. The connecting rod 22, which is vertically fixed at four ends of the connecting frame 21, rotates synchronously with the connecting frame 21. Since the lower end of the connecting rod 22 is vertically connected to the stirring rod 23, the stirring rod 23 will rotate on its own axis while revolving with the connecting rod 22 under the resistance of the wastewater. This will fully stir the wastewater in the second tank 3, promote the coagulation of fine impurities in the wastewater, accelerate the sedimentation speed of impurities, and improve sedimentation efficiency. Step four: While stirring and settling, the external air supply device is activated. Gas is stably delivered to the aeration disc 28, which is connected to the rear end of the aeration disc 28 installed on the bottom surface of the second tank 3, through an air pipe. The aeration disc 28 converts the gas into fine bubbles and releases them into the wastewater, creating an aeration effect. During aeration, pollutants in the wastewater are decomposed, further accelerating the sedimentation of fine impurities and improving the purification accuracy of the wastewater. In addition, the vertically arranged circular filter 24 inside the second tank 3 can further intercept fine impurities that have not completely settled after stirring and settling, further removing impurities from the wastewater and ensuring the wastewater treatment effect. A fixed frame 25 is installed on the lower outer side of the filter screen 24 and connected to the lifting frame 26. The four ends of the bottom surface of the lifting frame 26 are respectively connected to the output shaft of the electric push rod 27 installed on the bottom surface of the base 4. The lifting and lowering of the circular filter screen 24 can be controlled by the electric push rod 27. At the same time, the rotating shaft 20 is placed inside the circular filter screen 24, and the spiral blades installed on the outer side of the rotating shaft 20 abut against the inner wall of the circular filter screen 24. When the rotating shaft 20 rotates, the spiral blades will scrape and clean the inner wall of the circular filter screen 24, preventing fine impurities from adhering to the filter screen and causing blockage. At the same time, it can slowly push the impurities deposited in the circular filter screen 24 to the bottom for easy subsequent discharge. Step 5: After the wastewater in the second tank 3 has completed sedimentation and purification and meets the discharge standards, the wastewater and sediment can be discharged separately. If it is necessary to discharge the treated clean water, simply open the discharge valve 6 installed at the discharge port on the bottom of the base 4 and simultaneously close the servo motor 19. Since the lower end of the circular filter screen 24 abuts against the discharge port of the base 4, the circular filter screen 24 can intercept the sedimented impurities inside the circular filter screen 24, and the purified clean water can pass through the circular filter screen 24 and be discharged smoothly through the discharge valve 6. After all the clean water is discharged, start the electric push rod 27. The output shaft of the electric push rod 27 drives the lifting frame 26 to rise and fall. The lifting frame 26 drives the circular filter screen 24 to rise synchronously through the fixed frame 25 until the circular filter screen... When the filter screen 24 is disengaged from the discharge port of the base 4, the servo motor 19 is activated, and the rotating shaft 20 drives the spiral blades to rotate, accelerating the pushing of the impurities precipitated in the circular filter screen 24 to the discharge port of the base 4. The impurities are discharged through the discharge valve 6. After all the sediment is discharged, the discharge valve 6 is closed, and the servo motor 19, external water supply device, and external air supply device are also turned off. All electrical equipment is powered off. After a simple inspection of the device, the entire treatment operation of the ceramic production industrial wastewater is completed. Throughout the process, the first tank 1, the tank cover 2, the second tank 3, and the base 4 provide stable installation support for each component and mechanism, ensuring coordinated operation of each link and improving the efficiency and effect of wastewater treatment.
