By improving the internal structural components, the treatment device effectively improves the wastewater treatment efficiency and the wastewater treatment effect. Although such a setting effectively improves the wastewater treatment efficiency and the wastewater treatment effect by improving the internal structural components, there may be some impurities and debris in the wastewater. When filtering through the filter plate of this setting, after long-term use, the accumulated impurities will cause clogging of the filter plate, thereby affecting the filtration durability of the filter plate. Summary of the Invention

[0004] The object of the present invention is to provide a novel sodium carboxymethylcellulose wastewater treatment device to solve the problems raised in the above background technology.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a novel sodium carboxymethylcellulose wastewater treatment device, comprising a shell, a water inlet is provided on the top of the shell, a sewage outlet is provided on the outer wall of the shell, and a drain pipe is connected to the outer wall of the top of the shell; A cavity is provided on the inner side of the bottom of the shell, a stirring assembly is rotatably installed inside the cavity, a motor is installed on the outer wall of the shell, and the output shaft of the motor passes through the shell and is connected to the stirring assembly; A filter screen is rotatably connected to the inner wall of the housing, one end of the filter screen is formed into an arc shape, and the other end of the filter screen is inclined toward the port of the sewage outlet; A return assembly is installed on the inner wall of the shell, the return assembly is close to the inner side of the sewage outlet port, and the return assembly is above one end of the filter screen; A tension spring is connected between one end of the filter screen and the bottom inner wall of the shell; The filter is provided with a cleaning component, and the cleaning component operates during the rotation of the filter; The purpose of the above-mentioned setting is to pour wastewater into the interior of the shell through the water inlet and filter it through the filter. When the filter is flushed, the filter rotates and filters impurities in the wastewater. After rotation, it drives the cleaning component to operate, and the filtered water flows into the interior of the cavity. The motor drives the stirring component to operate. Some reaction reagents can be mixed before the wastewater flows in. During the stirring process, the reaction between the wastewater and the reagent is accelerated, thereby accelerating the wastewater treatment. After the filter rotates, one end of the filter and the return component are pressed against each other to prevent the wastewater from passing through the sewage outlet. When no wastewater is poured in, the tension of the tension spring pulls the filter to reset. At this time, there is a gap between the filter and the return component. It shakes when pulling and resetting. At the same time, the cleaning component moves and resets. Due to the shaking, impurities follow the slope of the filter, pass through the gap, and are discharged along the port of the sewage outlet. Therefore, after the wastewater is filtered, the blockage of the filter is reduced, the sustainability of the filter is enhanced, and the treated wastewater is discharged through the drain pipe.

[0006] Furthermore, the stirring assembly includes a cylinder, which is rotatably connected to the inner wall of the shell, a rotating shaft is installed on the inner side wall of the cylinder, the rotating shaft passes through the cylinder and the shell and is connected to the output shaft of the motor, and a plurality of arc-shaped blades are installed on the outer wall of the cylinder; The purpose of the above arrangement is that the output shaft of the motor drives the rotating shaft and the cylinder to rotate, thereby driving the arc-shaped blades to rotate and stirring the wastewater inside the cavity.

[0007] Furthermore, the outer wall of the cylinder is provided with through holes, and a plurality of the through holes are arranged in a ring shape on the outer wall of the cylinder. A plurality of mounting rings are connected to the outer wall of the rotating shaft, and an activated carbon rod is mounted on the inner wall of the mounting ring. The purpose of the above arrangement is that the wastewater passes through the through holes of the cylinder and is adsorbed and filtered by the activated carbon rods.

[0008] Furthermore, the return assembly includes a fixed plate, the fixed plate is mounted on the inner wall of the housing, the bottom of the fixed plate is rotatably connected to a rotating plate, a spring is connected between the outer wall of the rotating plate and the outer wall of the fixed plate, the rotating plate is in a vertical state, and a gap is left between the bottom end of the rotating plate and the upper surface of the filter screen; The purpose of the above setting is that in the initial state, the rotating plate is in a vertical state, and there is a gap between the bottom end of the rotating plate and the upper surface of the filter screen. When the filter screen rotates and tilts up, the rotating plate and the filter screen fit together to prevent waste water from passing through. The spring cooperates with the rotating plate to rotate, thereby adapting to the different rotation and tilting angles of the filter screen, so that the rotating plate and the filter screen remain in contact with each other during this process.

[0009] Furthermore, two inclined plates are provided at the water inlet port. In the initial state, the filtering end of the filter screen is in a tilted state, and the two inclined plates face the tilted end of the filter screen. The purpose of the above arrangement is that the wastewater flows along the inclined plate and impacts this end of the filter screen, thereby driving the filter screen to rotate.

[0010] Furthermore, the cleaning assembly includes a roller brush and a movable groove rail, wherein four movable groove rails are provided, two in a group, and the two groups of movable groove rails are respectively installed at both ends of the filter screen, and the two movable groove rails are respectively located on the upper surface and the lower surface of the filter screen, and the two roller brushes are provided, and the two roller brushes are respectively located on the upper surface and the lower surface of the filter screen; The purpose of the above-mentioned setting is to set the number and distribution of roller brushes and movable grooves, and the middle position of the filter screen rotates around a point on the inner wall of the shell, so that the inclination angle changes. In this process, one end is tilted and changed to the other end. The two movable grooves are respectively installed on the outer walls of both ends of the filter screen, and the two roller brushes are moved between the movable grooves through the rollers at both ends. The two roller brushes are respectively on the upper and lower surfaces of the filter screen. During the movement, the burrs of the roller brush rub against the holes of the filter screen to clean both sides of the filter screen.

[0011] Furthermore, both ends of the roller brush are rotatably connected to rollers, which move on the inner wall of the movable groove rail; The purpose of the above setting is that the roller moves on the inner wall of the movable groove rail, and the roller rolls. Compared with setting the slider to move, the moving friction is smaller, thereby preventing the roller brush from getting stuck when moving between the two movable groove rails.

[0012] The present invention has the following beneficial effects: (1) The present invention sets a cleaning component. When no waste water is poured in, the tension of the tension spring pulls the filter to reset. At this time, there is a gap between the filter and the return component. After pulling and resetting, the filter and the inside of the shell touch each other. The tension spring gives elasticity to one end of the filter, so that the filter shakes. At the same time, the cleaning component moves and resets. Due to the shaking, impurities follow the slope of the filter, pass through the gap, and are discharged along the port of the sewage outlet. Therefore, after the waste water is filtered, the blockage of the filter is reduced and the sustainability of the filter is enhanced.

[0013] (2) The present invention sets a return assembly. In the initial state, the rotating plate is in a vertical state. A gap is left between the bottom end of the rotating plate and the upper surface of the filter screen. When the filter screen rotates and tilts up, the rotating plate and the filter screen fit together to prevent wastewater from passing through. The spring cooperates with the rotating plate to rotate, thereby adapting to the different rotation and tilting angles of the filter screen, allowing the rotating plate and the filter screen to maintain mutual fit during this process.

When the filter screen 4 is flushed, the filter screen 4 rotates, and the filter screen 4 filters the impurities and debris in the waste water. After rotation, it drives the cleaning component to operate, and the filtered water flows into the interior of the cavity 103. The motor 2 drives the stirring component 3 to operate. Some reaction reagents can be mixed before the waste water flows in. During the stirring process, the reaction between the waste water and the reagent is accelerated, thereby accelerating the waste water treatment. After the filter screen 4 rotates, One end of the filter screen 4 is pressed against the return assembly 5 to prevent wastewater from passing through the sewage outlet 102. When no wastewater is poured in, the tension of the tension spring 6 pulls the filter screen 4 to reset. At this time, there is a gap between the filter screen 4 and the return assembly 5. When pulled to reset, it shakes. At the same time, the cleaning assembly moves and resets. Due to the shaking, impurities follow the slope of the filter screen 4, pass through the gap, and are discharged along the port of the sewage outlet 102. Therefore, after the wastewater is filtered, the blockage of the filter screen 4 is reduced, the sustainability of the use of the filter screen 4 is enhanced, and the treated wastewater is discharged through the drain pipe 104.

The bottom of the fixed plate 501 is rotatably connected to a rotating plate 503. A spring 502 is connected between the outer wall of the rotating plate 503 and the outer wall of the fixed plate 501. The rotating plate 503 is in a vertical state, and a gap is left between the bottom end of the rotating plate 503 and the upper surface of the filter 4. In this embodiment, the purpose of the above-mentioned setting is that, in the initial state, the rotating plate 503 is in a vertical state, and a gap is left between the bottom end of the rotating plate 503 and the upper surface of the filter screen 4. When the filter screen 4 is rotated and tilted, the rotating plate 503 and the filter screen 4 fit together to prevent waste water from passing through. The spring 502 cooperates with the rotating plate 503 to rotate, thereby adapting to the different rotation and tilting angles of the filter screen 4, so that the rotating plate 503 and the filter screen 4 remain in contact with each other during this process.

In the initial state, the filtering end of the filter 4 is in a tilted state, and the two inclined plates face the tilted end of the filter 4. In this embodiment, the purpose of the above arrangement is that the wastewater flows along the inclined plate to impact the end of the filter screen 4, thereby driving the filter screen 4 to rotate.

[0023] As an implementation method, Figure 6 As shown, further: The cleaning assembly includes a roller brush 8 and a movable groove rail 7. Four movable groove rails 7 are provided, two in a group, and the two groups of movable groove rails 7 are respectively installed at both ends of the filter screen 4. The two movable groove rails 7 are respectively located on the upper surface and the lower surface of the filter screen 4. Two roller brushes 8 are provided, and the two roller brushes 8 are respectively located on the upper surface and the lower surface of the filter screen 4; In this embodiment, the purpose of the above-mentioned setting is that the number and distribution of the roller brushes 8 and the movable groove rails 7 are set, and the middle position of the filter screen 4 rotates around a point on the inner wall of the shell 1, so that the inclination angle changes.

Compared with setting the slider to move, the moving friction is smaller, thereby preventing the roller brush 8 from getting stuck when moving between the two movable groove rails 7.

[0025] During use, the waste water is poured into the interior of the shell 1 through the water inlet 101 and filtered through the filter screen 4. When the filter screen 4 is flushed, the filter screen 4 rotates, and the filter screen 4 filters the impurities and sundries in the waste water. After rotation, the cleaning component is driven to operate. The middle position of the filter screen 4 rotates around a point on the inner wall of the shell 1, thereby changing the tilt angle. In this process, one end is tilted and transformed into the other end. The two movable groove rails 7 are respectively installed on the outer walls of the two ends of the filter screen 4. The two roller brushes 8 are respectively moved between the movable groove rails 7 by the rollers at both ends. The two roller brushes 8 are respectively on the upper surface and the lower surface of the filter screen 4. During the movement, the burrs of the roller brush 8 rub against the holes of the filter screen 4 to clean both sides of the filter screen 4. The filtered water flows into the cavity 10 3, the output shaft of the motor 2 drives the rotating shaft 303 and the cylinder 301 to rotate, thereby driving the arc-shaped blade 302 to rotate, stirring the wastewater inside the cavity 103, and mixing some reaction reagents before the wastewater flows in. During the stirring process, the reaction between the wastewater and the reagent is accelerated, thereby accelerating the wastewater treatment. After the filter screen 4 rotates, in the initial state, the rotating plate 503 is in a vertical state, and a gap is left between the bottom end of the rotating plate 503 and the upper surface of the filter screen 4. When the filter screen 4 rotates and tilts up, the rotating plate 503 and the filter screen 4 fit together to prevent wastewater from passing through. The spring 502 cooperates with the rotating plate 503 to rotate, thereby adapting to the different rotation and tilting angles of the filter screen 4, so that the rotating plate 503 and the filter screen 4 keep fit with each other during this process, preventing wastewater from passing through the sewage outlet 102; When no wastewater is poured in, the tension of the tension spring 6 pulls the filter 4 to reset. At this time, there is a gap between the filter 4 and the return assembly 5. After pulling and resetting, the filter 4 and the inside of the shell 1 touch each other. The tension spring 6 gives one end of the filter 4 elasticity, so that the filter 4 shakes. At the same time, the cleaning assembly moves and resets. Due to the shaking, impurities follow the slope of the filter 4, pass through the gap, and are discharged along the port of the sewage outlet 102. Therefore, after the wastewater is filtered, the blockage of the filter 4 is reduced, and the sustainability of the use of the filter 4 is enhanced.
