Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and specifically to a wastewater treatment device for sodium carboxymethylcellulose. Background Art

[0002] Sodium carboxymethylcellulose is a common water-soluble polymer material, widely used in industries such as food, medicine, petroleum, and papermaking. It is a cellulose ether compound obtained by introducing carboxymethyl (-CH2COOH) groups onto the molecular chain of natural cellulose. Sodium carboxymethylcellulose has stable physical and chemical properties and exhibits excellent functions such as thickening, emulsifying, and bonding in various environments. A wastewater treatment device is a device used to treat various types of wastewater, aiming to remove pollutants in the wastewater, thereby reducing environmental pollution and waste of water resources.

[0003] Chinese patent application with the application number CN202311238125.3 discloses a wastewater treatment device, including a physical filtration chamber, a chemical reaction chamber, and a disinfection chamber connected in sequence; a filtration component is arranged in the physical filtration chamber, a driving mechanism is arranged at the upper end of the chemical reaction chamber, a stirring mechanism is arranged on the output shaft of the driving mechanism, a disinfection component and a partition board are arranged in the disinfection chamber, the partition board is located below the disinfection component, and a third drain pipe is arranged at the lower part of the disinfection chamber. This treatment device effectively improves the wastewater treatment efficiency and the wastewater treatment effect by improving the internal structural components;

[0004] 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 sundries in the wastewater. When filtering through the filter plate of this setting, after long-term use, the accumulated impurities will block the filter plate, thereby affecting the filtering durability of the filter plate. Summary of the Invention

[0005] The purpose of the present invention is to provide a wastewater treatment device for sodium carboxymethylcellulose to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] The present invention is a wastewater treatment device for sodium carboxymethylcellulose, including a housing. An inlet is provided at the top of the housing, a sewage outlet is provided on the outer wall of the housing, and a drain pipe is communicated with the top outer wall of the housing;

[0008] A cavity is arranged inside the bottom of the housing, a stirring component is rotatably installed inside the cavity, a motor is installed on the outer wall of the housing, and the output shaft of the motor penetrates the housing and is connected to the stirring component;

[0009] A filter screen is rotatably connected to the inner wall of the housing. One end of the filter screen forms an arc, and the other end of the filter screen inclines towards the port of the sewage outlet.

[0010] A return component is installed on the inner wall of the housing. The return component is close to the inner side of the port of the sewage outlet and is located above one end of the filter screen.

[0011] A tension spring is connected between one end of the filter screen and the bottom inner wall of the housing.

[0012] A cleaning component is arranged on the filter screen. The cleaning component operates during the rotation of the filter screen.

[0013] The purpose of the above settings is to pour the wastewater into the interior of the housing through the water inlet and filter it through the filter screen. When the filter screen is washed, the filter screen rotates. The filter screen filters the impurities and sundries in the wastewater. After rotation, it drives the cleaning component to operate. The filtered wastewater flows into the interior of the cavity. The motor drives the stirring component to operate, and 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 screen rotates, one end of the filter screen abuts against the return component 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 screen to reset. At this time, there is a gap between the filter screen and the return component. When pulling and resetting, it vibrates. At the same time, the cleaning component moves and resets. Affected by the vibration, the impurities slide down the slope of the filter screen, pass through the gap, and flow out along the port of the sewage outlet. Thus, after the wastewater is filtered, the blockage of the filter screen is reduced, and the service life of the filter screen is enhanced. The treated wastewater is discharged through the drain pipe.

[0014] Further, the stirring component includes a cylinder body. The cylinder body is rotatably connected to the inner wall of the housing. A rotating shaft is installed on the inner side wall of the cylinder body. The rotating shaft passes through the cylinder body and the housing and is connected to the output shaft of the motor. A plurality of arc-shaped vanes are installed on the outer wall of the cylinder body.

[0015] The purpose of the above settings is that the output shaft of the motor drives the rotating shaft and the cylinder body to rotate, thereby driving the arc-shaped vanes to rotate and stirring the wastewater in the cavity.

[0016] Further, through holes are provided on the outer wall of the cylinder body. A plurality of the through holes are annularly arranged on the outer wall of the cylinder body. A plurality of mounting rings are connected to the outer wall of the rotating shaft. Activated carbon rods are installed on the inner walls of the mounting rings.

[0017] The purpose of the above settings is that the wastewater passes through the through holes of the cylinder body and is adsorbed and filtered by the activated carbon rods.

[0018] Further, the return component includes a fixing plate installed on the inner wall of the housing. A rotating plate is rotatably connected to the bottom of the fixing plate. A spring is connected between the outer wall of the rotating plate and the outer wall of the fixing plate. 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 net.

[0019] 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 net. When the filter net rotates and tilts up, the rotating plate fits with the filter net to prevent wastewater from passing through. The spring cooperates with the rotation of the rotating plate to adapt to different rotation and tilting angles of the filter net, so that the rotating plate and the filter net remain in mutual fit during this process.

[0020] Further, two inclined plates are provided at the port of the water inlet. In the initial state, the filtering end of the filter net is in a tilted-up state, and the two inclined plates face the tilted-up end of the filter net.

[0021] The purpose of the above setting is that the wastewater flows along the inclined plates to impact this end of the filter net, thereby driving the filter net to rotate.

[0022] Further, the cleaning component includes a roller brush and moving groove rails. There are four moving groove rails, two in a group. The two groups of moving groove rails are respectively installed at both ends of the filter net. The two moving groove rails are respectively on the upper surface and the lower surface of the filter net. There are two roller brushes, and the two roller brushes are respectively on the upper surface and the lower surface of the filter net.

[0023] The purpose of the above setting is that due to the number and distribution of the roller brush and the moving groove rails, the middle position of the filter net rotates around a point on the inner wall of the housing, resulting in a change in the tilt angle. During this process, one end tilts up and changes to the other end tilting up. The two moving groove rails are respectively installed on the outer walls at both ends of the filter net. The two roller brushes respectively move between the moving groove rails through the rollers at both ends. The two roller brushes are respectively on the upper surface and the lower surface of the filter net. During the movement, the bristles of the roller brush rub against the holes of the filter net to clean both sides of the filter net.

[0024] Further, rollers are respectively rotatably connected to both ends of the roller brush, and the rollers move on the inner wall of the moving groove rail.

[0025] The purpose of the above setting is that the rollers move on the inner wall of the moving groove rail and roll. Compared with setting the movement of sliders, the moving friction is smaller, thus preventing the roller brush from getting stuck during the movement between the two moving groove rails.

[0026] The present invention has the following beneficial effects:

[0027] (1) Through the arrangement of the cleaning component, when no waste water is poured in, the pulling force of the tension spring pulls the filter net to reset. At this time, there is a gap between the filter net and the backstop component. After the pulling reset, the filter net touches the inside of the housing. The tension spring gives one end of the filter net elasticity, so that the filter net vibrates. At the same time, the cleaning component moves back to its original position. Affected by the vibration, impurities slide along the slope of the filter net, pass through the gap, and are discharged along the port of the sewage outlet. Thus, after the waste water is filtered, the blockage of the filter net is reduced, and the service life of the filter net is enhanced.

[0028] (2) Through the arrangement of the backstop component, 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 net. When the filter net rotates and tilts up, the rotating plate fits with the filter net to prevent waste water from passing through. The spring cooperates with the rotation of the rotating plate to adapt to different rotation and tilting angles of the filter net, so that the rotating plate and the filter net remain in mutual fit during this process.

[0029] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] The present invention is a sodium carboxymethylcellulose wastewater treatment device, as Figures 1 - 8 shown, including a housing 1. A water inlet 101 is provided at the top of the housing 1. A sewage outlet 102 is provided on the outer wall of the housing 1. A drain pipe 104 is communicated with the top outer wall of the housing 1;

[0043] A cavity 103 is provided inside the bottom of the housing 1. A stirring assembly 3 is rotatably installed inside the cavity 103. A motor 2 is installed on the outer wall of the housing 1. The output shaft of the motor 2 penetrates the housing 1 and is connected to the stirring assembly 3;

[0044] A filter screen 4 is rotatably connected to the inner wall of the housing 1. One end of the filter screen 4 forms an arc, and the other end of the filter screen 4 inclines towards the port of the sewage outlet 102;

[0045] A backstop assembly 5 is installed on the inner wall of the housing 1. The backstop assembly 5 is close to the inner side of the port of the sewage outlet 102, and the backstop assembly 5 is above one end of the filter screen 4;

[0046] A tension spring 6 is connected between one end of the filter screen 4 and the bottom inner wall of the housing 1;

[0047] A cleaning assembly is provided on the filter screen 4, and the cleaning assembly operates during the rotation of the filter screen 4;

[0048] In this embodiment, the purpose of the above settings is to pour wastewater into the interior of the housing 1 through the water inlet 101 and filter it through the filter screen 4. When the filter screen 4 is washed, the filter screen 4 rotates. The filter screen 4 filters impurities and sundries in the wastewater. After rotation, it drives the cleaning component to operate. After filtration, the wastewater flows into the interior of the cavity 103. The motor 2 drives the stirring component 3 to operate, and 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 screen 4 rotates, one end of the filter screen 4 abuts tightly against the blocking component 5 to prevent the wastewater from passing through the sewage outlet 102. When no wastewater is poured in, the pulling force 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 blocking component 5. When pulling to reset, it vibrates, and at the same time, the cleaning component moves to reset. Due to the vibration, the impurities slide down the slope of the filter screen 4, pass through the gap, and are discharged along the port of the sewage outlet 102. Thus, after the wastewater is filtered, the blockage of the filter screen 4 is reduced, and the service life of the filter screen 4 is enhanced. The treated wastewater is discharged through the drain pipe 104.

[0049] As an implementation method, as Figure 4 shown, further:

[0050] The stirring component 3 includes a cylinder body 301. The cylinder body 301 is rotatably connected to the inner wall of the housing 1. A rotating shaft 303 is installed on the inner side wall of the cylinder body 301. The rotating shaft 303 passes through the cylinder body 301 and the housing 1 and is connected to the output shaft of the motor 2. A number of arc-shaped blades 302 are installed on the outer wall of the cylinder body 301;

[0051] In this embodiment, the purpose of the above settings is that the output shaft of the motor 2 drives the rotating shaft 303 and the cylinder body 301 to rotate, thereby driving the arc-shaped blades 302 to rotate and stirring the wastewater inside the cavity 103.

[0052] As an implementation method, as Figure 4 shown, further:

[0053] Through holes are provided on the outer wall of the cylinder body 301. A number of through holes are arranged annularly on the outer wall of the cylinder body 301. A number of mounting rings 304 are connected to the outer wall of the rotating shaft 303. Activated carbon rods 9 are installed on the inner wall of the mounting rings 304;

[0054] In this embodiment, the purpose of the above settings is that the wastewater passes through the through holes of the cylinder body 301 and is adsorbed and filtered by the activated carbon rods 9.

[0055] As an implementation method, as Figure 5 shown, further:

[0056] The return component 5 includes a fixing plate 501 which is installed on the inner wall of the housing 1. A rotating plate 503 is rotatably connected to the bottom of the fixing plate 501. A spring 502 is connected between the outer wall of the rotating plate 503 and the outer wall of the fixing plate 501. The rotating plate 503 is in a vertical state, and there is a gap between the bottom end of the rotating plate 503 and the upper surface of the filter net 4.

[0057] In this embodiment, the purpose of the above setting is that in the initial state, the rotating plate 503 is in a vertical state, and there is a gap between the bottom end of the rotating plate 503 and the upper surface of the filter net 4. When the filter net 4 rotates and tilts up, the rotating plate 503 fits with the filter net 4 to prevent wastewater from passing through. The spring 502 cooperates with the rotation of the rotating plate 503 to adapt to different rotation and tilt angles of the filter net 4, so that the rotating plate 503 and the filter net 4 remain in mutual fit during this process.

[0058] As an implementation manner, as Figure 1 and Figure 5 shown, further:

[0059] There are two inclined plates arranged at the port of the water inlet 101. In the initial state, the filtering end of the filter net 4 is in a tilted state, and the two inclined plates face the tilted end of the filter net 4.

[0060] In this embodiment, the purpose of the above setting is that the wastewater flows along the inclined plates to impact this end of the filter net 4, thereby driving the filter net 4 to rotate.

[0061] As an implementation manner, as Figure 6 shown, further:

[0062] The cleaning component includes a roller brush 8 and a moving groove track 7. There are four moving groove tracks 7, two in a group. The two groups of moving groove tracks 7 are respectively installed at both ends of the filter net 4. The two moving groove tracks 7 are respectively on the upper surface and the lower surface of the filter net 4. There are two roller brushes 8, and the two roller brushes 8 are respectively on the upper surface and the lower surface of the filter net 4.

[0063] In this embodiment, the purpose of the above setting is that due to the number and distribution of the roller brush 8 and the moving groove track 7, the middle position of the filter net 4 rotates around a point on the inner wall of the housing 1, resulting in a change in the tilt angle. During this process, one end tilts up and changes to the other end tilting up. The two moving groove tracks 7 are respectively installed on the outer walls at both ends of the filter net 4. The two roller brushes 8 respectively move between the moving groove tracks 7 through the rollers at both ends. The two roller brushes 8 are respectively on the upper surface and the lower surface of the filter net 4. During the movement, the bristles of the roller brush 8 rub against the holes of the filter net 4 to clean both sides of the filter net 4.

[0064] As an implementation manner, asFigure 6 As shown, further:

[0065] The two ends of the roller brush 8 are rotatably connected with rollers, which move on the inner wall of the moving groove rail 7;

[0066] In this embodiment, the purpose of the above-mentioned setting is that the roller moves on the inner wall of the movable groove rail 7, and the roller rolls. 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.

[0067] When in 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 debris in the waste water. After the 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, so that the inclination angle changes. In this process, one end is tilted and transformed into the other end. The two movable grooves 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 grooves 7 through 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 to 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 blade 302 to rotate, stirring the wastewater inside the cavity 103, and 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 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 the 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 fitting together in this process to prevent the wastewater from passing through the sewage outlet 102;

[0068] When no waste water 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 elasticity to one end of the filter 4, 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 waste water is filtered, the blockage of the filter 4 is reduced, and the sustainability of the use of the filter 4 is enhanced. The waste water passes through the through hole of the cylinder 301, is adsorbed and filtered by the activated carbon rod 9, and is discharged through the drain pipe 104.
