Description

Technical Field

[0001] The invention relates to the technical field of pure water classification filtration and cleaning, in particular to an automated pure water ultrafiltration treatment device. Background Art

[0002] Pure water ultrafiltration treatment is a highly efficient water purification technology that uses membrane separation principles to push water molecules through ultrafiltration membrane cartridges of specific pore sizes through pressure. Ultrafiltration membrane cartridges have extremely small pore sizes (usually between 0.005-0.1 microns), which can effectively remove suspended matter, colloids, bacteria, viruses and other macromolecules in the water, ensuring the purity of the water quality, thereby achieving effective removal of impurities in the water.

[0003] The prior art still has the following defects when used specifically:

[0004] 1. Since the ultrafiltration membrane cartridge uses its tiny pores to intercept suspended matter, colloids, bacteria and other impurities in the water, these impurities gradually accumulate on the membrane surface to form a pollution layer. The pollution on the surface of the ultrafiltration membrane cartridge includes organic pollution, inorganic pollution, microbial pollution and other types. These pollutants have different physical and chemical properties, which makes the cleaning process complicated and hinders the normal passage of water molecules. Since the existing equipment cannot automatically clean the surface of the ultrafiltration membrane cartridge after filtering pure water, it will cause the ultrafiltration membrane cartridge to accumulate for a long time, resulting in the generation of organic, inorganic, microbial and other pollutants on the surface of the ultrafiltration membrane cartridge, so that all types of pollutants cannot be completely removed during cleaning, resulting in reduced water quality treatment effect.

[0005] 2. The existing pure water cannot collect the cleaned impurities uniformly after ultrafiltration, resulting in the impurities settling at the bottom. Impurities that are not effectively collected may be released back into the water, causing the quality of the treated water to deteriorate and fail to meet the expected purity requirements. Some impurities may contain harmful substances, such as heavy metals, bacteria, etc. If they are not effectively removed, they may pose a potential threat to human health.

[0006] Therefore, an automated pure water ultrafiltration treatment device is proposed to solve the above problems. Summary of the invention

[0018] Compared with the prior art, the present invention provides an automated pure water ultrafiltration treatment device having the following features:

[0019] Beneficial effects:

[0020] 1. Through the setting of the ratchet and the slot ring in the multifunctional rotating adjustment mechanism, when the motor is set to rotate clockwise, it will drive the ultrafiltration membrane cartridge assembly to work efficiently. By utilizing the screening effect of the membrane pore size, the flow characteristics of dynamic filtration help to enhance the flushing effect on impurities in the water. With the continuous rotation of the membrane surface, impurities such as suspended matter, colloids and bacteria in the water flow are more easily peeled off the membrane surface and discharged with the water flow under the combined effect of the shear force and centrifugal force of the water flow. This flushing effect not only reduces the pollutant load on the membrane surface, but also avoids the blockage of the membrane pores caused by the accumulation of pollutants, thereby ensuring the stability and high efficiency of the filtration efficiency;

[0021] Compared with the existing technology of ultrafiltration of pure water by fixedly pressurizing it onto the ultrafiltration membrane, the sensor automatically identifies and controls the direction of motor rotation so that the spray chamber can perform ultrafiltration at different heights of the ultrafiltration membrane cylinder. This can not only avoid excessive accumulation of pure water on the membrane surface and reduce mechanical stress and chemical erosion on the membrane surface, but also timely clean and maintain the membrane surface, which can significantly extend the service life of the ultrafiltration membrane and reduce replacement costs. Compared with fixed pressurization, the automatic adjustment system can be flexibly adjusted according to different water quality, water volume and treatment requirements. This flexibility enables the system to better adapt to various complex and changeable working environments and improve the overall treatment effect.

[0022] 2. When the pure water ultrafiltration is completed and the motor is adjusted to rotate counterclockwise, the system automatically switches to the cleaning mode. At this time, the motor drives the spray chamber to reciprocate in the ultrafiltration membrane cylinder to thoroughly clean the surface of the ultrafiltration membrane cylinder. The arrangement of the present invention not only solves the problem that impurities are easily accumulated on the membrane surface in the traditional ultrafiltration process, but also effectively prevents the occurrence of membrane pollution and blockage. By automatically cleaning after the ultrafiltration is completed, not only the service life of the ultrafiltration membrane cylinder is extended, but also the stability of the filtration efficiency and the continuous high quality of the effluent water are guaranteed.

[0023] 3. Through the setting of automatic cleaning and sewage discharge mechanism, the bottom of the liquid spray chamber is linked with the push column while the liquid spray chamber is reciprocating for cleaning. When the liquid spray chamber is squeezed onto the surface of the push column, the sewage discharge port opened in the rotatable closing disk and the fixed closing disk will be driven to be connected to each other, so that the dirt cleaned on the surface of the ultrafiltration membrane cylinder can be discharged into the dirt collection bucket through the sewage discharge port for collection through the sewage discharge port. The automatic cleaning and sewage discharge mechanism can accurately drive the rotatable closing disk and the sewage discharge port in the fixed closing disk to be connected to each other, ensuring that the dirt generated during the cleaning process can be accurately discharged into the dirt collection bucket through the sewage discharge port. The sewage discharge design in the present invention avoids secondary pollution of dirt and ensures the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0037] Example

[0038] Please refer to Figures 1 to 7 As shown:

[0039] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an automated pure water ultrafiltration treatment device, including a filter chamber 1, a pure water injection device 11 is installed on one side of the upper surface of the filter chamber 1, a cleaning injection device 12 is installed on the other side of the upper surface of the filter chamber 1, a separation tank 13 is fixedly connected to the middle of the filter chamber 1, an ultrafiltration membrane cartridge 14 is arranged in the middle of the separation tank 13, and also includes a multifunctional rotation adjustment mechanism 2 and an automatic cleaning and sewage discharge mechanism 3, the multifunctional rotation adjustment mechanism 2 is arranged above the filter chamber 1, and the automatic cleaning and sewage discharge mechanism 3 is arranged at the bottom of the filter chamber 1;

[0040] The multifunctional rotating adjustment mechanism 2 is used for filtering and cleaning the ultrafiltration membrane cartridge 14;

[0041] The automatic cleaning and drainage mechanism 3 is used to collect dirt after the ultrafiltration membrane cartridge 14 is cleaned;

[0042] The multifunctional rotating adjustment mechanism 2 includes a reciprocating screw 21, a water injection groove is provided in the middle of the reciprocating screw 21, the water injection groove at one end of the reciprocating screw 21 is fixedly connected to the pure water injection device 11 and the cleaning injection device 12, and the other end of the reciprocating screw 21 is fixedly connected to the spray chamber 28, and an arc-shaped extrusion groove is provided in the reciprocating screw 21;

[0043] An arc-shaped extrusion block 22 is slidably connected in the arc-shaped extrusion groove of the reciprocating screw rod 21 , and a gear ring 23 is rotatably connected to the middle of the arc-shaped extrusion block 22 .

[0044] One end of the torsion spring is fixedly connected to the pawl 24, and the other end is fixedly connected to the gear ring 23. A slot ring 25 is arranged outside the gear ring 23. The bottom of the slot ring 25 is slidably connected to the upper end of the ultrafiltration membrane cylinder 14. A slot is provided in the slot ring 25, and the pawl 24 is engaged in the slot of the slot ring 25.

[0045] A turntable 26 is engaged in the middle of the upper surface of the ultrafiltration membrane cartridge 14, and the outer periphery of the turntable 26 is rotatably connected to the inner wall of the separation tank 13. An angled toothed belt ring 27 is fixedly connected to the outer periphery of the upper surface of the turntable 26, and the tooth surface of the angled toothed belt ring 27 is meshed with conical teeth 29, and the middle part of the conical teeth 29 is rotatably connected to the inner wall of the separation tank 13;

[0046] The outer ring of the gear ring 23 is provided with a sliding groove, the sliding groove of the gear ring 23 is rotatably connected with a ratchet 24, and the ratchet 24 is provided with a torsion spring;

[0047] In the prior art, since the existing equipment cannot automatically clean the surface of the ultrafiltration membrane cylinder 14 after filtering pure water, it will cause the ultrafiltration membrane cylinder 14 to produce various pollutants such as organic matter, inorganic matter, and microorganisms on the surface of the ultrafiltration membrane cylinder 14 after a long period of accumulation, so that all types of pollutants cannot be completely removed during cleaning, resulting in reduced water quality treatment effect. Compared with the prior art, through the implementation of this embodiment, the sensor automatically identifies and controls the rotation direction of the motor so that the spray chamber 28 can perform ultrafiltration at different positions and heights of the ultrafiltration membrane cylinder 14, which can not only avoid excessive accumulation of pure water on the membrane surface, reduce mechanical stress and chemical erosion on the membrane surface, but also timely clean and maintain the membrane surface, which can significantly extend the service life of the ultrafiltration membrane and reduce replacement costs. Compared with fixed boosting, the automatic adjustment system can be flexibly adjusted according to different water quality, water volume and treatment requirements. This flexibility enables the system to better adapt to various complex and changeable working environments and improve the overall treatment effect.

[0048] For further examples, please refer to Figures 1 to 7 As shown:

[0049] The automatic cleaning and sewage discharge mechanism 3 includes a push column 31, an arc groove 32 is formed on the outer surface of the push column 31, a rotatable closing disk 33 and a fixed closing disk 34 are sleeved on the outer surface of the middle part of the push column 31, and the rotatable closing disk 33 is slidably connected to the upper surface of the fixed closing disk 34;

[0050] The fixed closing disk 34 is fixedly connected with an extrusion column, and the extrusion column is slidably connected in the arc groove 32. The outer periphery of the fixed closing disk 34 is rotatably connected with a fixed support plate 36. The bottom of the fixed support plate 36 is fixedly connected to the middle of the filter bin 1. The outer periphery of the rotatable closing disk 33 is fixedly connected to the fixed support plate 36.

[0051] A return spring 35 is fixedly connected to the bottom of the push column 31, and a bracket is fixedly connected to one end of the return spring 35 away from the push column 31, and the bracket is fixedly connected to the fixed support plate 36 on all sides. A dirt collection bucket 37 is threadedly connected to the bottom of the filter bin 1, and the dirt collection bucket 37 is used to collect filtered sludge and impurities;

[0052] Wherein: a sensor device is arranged in the ultrafiltration membrane cylinder 14, through which the rotation of the motor can be controlled; a connection control valve is arranged on the reciprocating screw 21, which can control the connection switching between the middle part of the reciprocating screw 21 and the pure water injection device 11 and the cleaning injection device 12.

[0053] In the prior art, the impurities washed after ultrafiltration of pure water cannot be uniformly collected by washing, resulting in the precipitation of impurities at the bottom. Impurities that are not effectively collected may be released into the water again, causing the quality of the treated water to deteriorate and fail to meet the expected purity requirements. Some impurities may contain harmful substances, such as heavy metals, bacteria, etc., which may pose a potential threat to human health if they are not effectively removed. Compared with the prior art, through the implementation of this embodiment, the spray chamber 28 is reciprocated while washing, and the bottom of the spray chamber 28 is linked with the push column 31. When the spray chamber 28 is squeezed to the push column 31, the spray chamber 28 is pressed to the push column 31. When the surface of the column 31 is cleaned, the rotatable closing disk 33 will be driven to communicate with the sewage outlet opened in the fixed closing disk 34, so that the dirt cleaned on the surface of the ultrafiltration membrane cartridge 14 can be discharged into the dirt collection bucket 37 through the sewage outlet for collection. The automatic cleaning sewage discharge mechanism 3 is set to be able to accurately drive the rotatable closing disk 33 and the sewage outlet in the fixed closing disk 34 to communicate with each other, ensuring that the dirt generated during the cleaning process can be accurately discharged into the dirt collection bucket 37 through the sewage outlet. The sewage discharge design in the present invention avoids secondary pollution of dirt and ensures the cleaning effect.

[0054] Everything in the above example works like this:

[0055] In the initial state: the return spring 35 is not compressed and the motor is not started.

[0056] The following is the working process of the multifunctional rotary adjustment mechanism 2 for filtering and cleaning the ultrafiltration membrane cartridge 14:

[0057] When the pure water filtration is started, the pure water injection device 11 is connected to the reciprocating screw 21 by the valve control device arranged above the reciprocating screw 21, and the pure water is pressurized and delivered to the spray chamber 28 through the pure water injection device 11. At this time, under the control of electric start, the motor starts to rotate clockwise. When the motor rotates clockwise, as shown in FIG. Figure 4 As shown, because the motor drive shaft is fixedly connected to the middle of the conical tooth 29, and the tooth surface of the conical tooth 29 is meshed with the bevel tooth belt ring 27, the clockwise rotation of the motor drive shaft will drive the conical tooth 29 to drive the bevel tooth belt ring 27 to start counterclockwise rotation around the reciprocating screw 21. At this time, because the bottom of the bevel tooth belt ring 27 is fixedly connected to the turntable 26, the counterclockwise rotation of the bevel tooth belt ring 27 will drive the turntable 26 to start synchronous rotation;

[0058] At this time, because the upper end of the pawl 24 is stuck in the middle of the turntable 26, the turntable 26 rotates counterclockwise to drive the ultrafiltration membrane cartridge 14 to start rotating counterclockwise synchronously. Figure 5 As shown, because the internal groove of the groove ring 25 fixedly connected to the middle part of the upper end of the ultrafiltration membrane cartridge 14 is engaged with the pawl 24, due to the setting of the groove, when the ultrafiltration membrane cartridge 14 drives the groove ring 25 to rotate, the groove of the groove ring 25 and the surface of the pawl 24 are squeezed against each other, causing the pawl 24 to begin to close in the gear ring 23 in the counterclockwise direction. At this time, the counterclockwise rotation of the groove ring 25 will not drive the gear ring 23 and the reciprocating screw 21 to rotate, so that when the cleaning injection device 12 is driven by the motor to rotate, pure water is pressurized and sprayed onto the ultrafiltration membrane of the ultrafiltration membrane cartridge 14 through the pure water injection device 11 for filtration. At this time, the rotation of the ultrafiltration membrane cartridge 14 will evenly cover the pure water on the ultrafiltration membrane cartridge 14, and the rotation of the ultrafiltration membrane The water forms a dynamic flow on the membrane surface, which is not only conducive to reducing the deposition of pollutants on the membrane surface and improving the filtration flux, but the flow characteristics of dynamic filtration are also helpful to enhance the flushing effect on impurities in the water. As the membrane surface continues to rotate, impurities such as suspended matter, colloids and bacteria in the water flow are more easily peeled off the membrane surface and discharged with the water flow under the combined action of the shear force and centrifugal force of the water flow. This flushing effect not only reduces the pollutant load on the membrane surface, but also avoids the blockage of the membrane pores caused by the accumulation of pollutants, thereby ensuring the stability and efficiency of the filtration efficiency. In the process of rotation, pure water can be more evenly distributed on the membrane surface, avoiding excessive pollution or blockage in local areas, thereby improving the overall filtration efficiency.

[0059] Through the setting of the ratchet 24 and the groove ring 25 in the multifunctional rotating adjustment mechanism 2, when the motor is set to rotate clockwise, it will drive the ultrafiltration membrane cartridge 14 assembly to work efficiently, and utilize the screening effect of the membrane pore size to effectively intercept impurities such as suspended matter, colloids, bacteria, etc. in the water, thereby achieving pure water filtration. This process ensures the purity of the effluent water quality;

[0060] Compared with the prior art which performs ultrafiltration of pure water by fixedly pressurizing pure water onto an ultrafiltration membrane, the sensor automatically identifies and controls the rotation direction of the motor so that the spray chamber 28 can perform ultrafiltration at different heights of the ultrafiltration membrane cylinder 14, which can not only avoid excessive accumulation of pure water on the membrane surface, but also reduce the mechanical stress and chemical erosion on the membrane surface.

[0061] Please refer to the above working process Figures 1 to 7 .

[0062] The following is the working process of the automatic cleaning and drainage mechanism 3 for anti-floating collection of stains:

[0063] When the pure water filtration is completed as described above, the motor starts to rotate counterclockwise through the automatic control of the controller. As described above, the counterclockwise rotation of the motor will cause the conical teeth 29 to drive the bevel gear belt ring 27 to start rotating clockwise. At this time, the clockwise rotation of the bevel gear belt ring 27 will drive the turntable 26 to drive the ultrafiltration membrane cartridge 14 to start rotating clockwise. Figure 5 As shown, when the slot in the slot ring 25 rotates counterclockwise, it will engage with the pawl 24. The counterclockwise rotation of the slot ring 25 will drive the pawl 24 to drive the gear ring 23 to start rotating counterclockwise. At this time, since a reciprocating groove is provided in the reciprocating screw 21, and the arc-shaped extrusion block 22 is slidably connected in the reciprocating groove, and since the arc-shaped extrusion block 22 is rotatably connected to the surface of the gear ring 23, the counterclockwise rotation of the gear ring 23 will drive the arc-shaped extrusion block 22 to slide in the reciprocating groove. Under the action of the arc-shaped extrusion block 22 and the reciprocating groove, the reciprocating screw 21 will start to slide back and forth in the ultrafiltration membrane cylinder 14.

[0064] When the pure water ultrafiltration is completed, the motor is adjusted to rotate counterclockwise, and the system automatically switches to the cleaning mode. At this time, the reciprocating screw 21 is driven by the motor to drive the spray chamber 28 to reciprocate in the ultrafiltration membrane cylinder 14, so as to thoroughly clean the surface of the ultrafiltration membrane cylinder 14. With the reciprocating motion of the spray chamber 28, the ultrafiltration membrane cylinder 14 rotates synchronously counterclockwise, and the tiny impurities and dirt attached to the ultrafiltration membrane cylinder 14 are cleaned by the cleaning agent in the spray chamber 28 under the rotation of the ultrafiltration membrane cylinder 14. Under the action of the water, the dirt attached to the ultrafiltration membrane pores is peeled off one by one and flows downward with the water. This process is not only a deep cleaning of the ultrafiltration membrane cartridge 14, but also solves the problem of impurities easily accumulating on the membrane surface in the traditional ultrafiltration process, effectively preventing the occurrence of membrane pollution and blockage, but also is a strong guarantee for its service life and filtration efficiency. Moreover, through automatic cleaning after the ultrafiltration is completed, not only the service life of the ultrafiltration membrane cartridge 14 is extended, but also the stability of the filtration efficiency and the continuous high quality of the effluent water are guaranteed.

[0065] When the reciprocating screw rod 21 drives the spray chamber 28 to slide until it is pressed against the push post 31, the return spring 35 begins to be compressed on the fixed frame in the middle of the fixed support plate 36. The push post 31 starts to slide downward for a distance through the downward pressure of the spray chamber 28, and then the reciprocating screw rod 21 slides upward again through the reciprocating slide groove. Figure 7As shown, when the push post 31 slides downward, the squeezing post on the rotatable closing disk 33 is slidably connected in the arc groove 32, so the push post 31 slides downward, which drives the rotatable closing disk 33 to start rotating counterclockwise on the fixed support plate 36. At this time, because the rotatable closing disk 33 and the fixed closing disk 34 fit each other, and the sewage outlets opened in the rotatable closing disk 33 and the fixed closing disk 34 are closed to each other, and because the fixed closing disk 34 is fixedly connected to the fixed support plate 36, when the rotatable closing disk 33 is rotated, the rotatable closing disk 33 and the fixed closing disk 34 are rotated. When the closing disk 33 rotates counterclockwise on the fixed support plate 36, the sewage outlets of the rotatable closing disk 33 and the fixed closing disk 34 are gradually connected to each other. At this time, the dirt cleaned on the ultrafiltration membrane cartridge 14 will fall into the dirt collection bucket 37 through the sewage outlet for collection. When the push column 31 is no longer squeezed, the push column 31 will slide upward under the elastic action of the return spring 35. At this time, the squeeze between the arc groove 32 and the squeezing column will drive the sewage outlets of the rotatable closing disk 33 and the fixed closing disk 34 to close again. The liquid spray chamber 28 is reciprocatingly cleaned while the bottom of the liquid spray chamber 28 is linked with the push column 31. When the liquid spray chamber 28 is squeezed onto the surface of the push column 31, the rotatable closing disc 33 is driven to communicate with the sewage outlet opened in the fixed closing disc 34, so that the dirt cleaned on the surface of the ultrafiltration membrane cartridge 14 can be discharged into the dirt collection bucket 37 through the sewage outlet for collection. The automatic cleaning sewage discharge mechanism 3 is set to accurately drive the rotatable closing disc 33 to communicate with the sewage outlet in the fixed closing disc 34, and the liquid spray chamber During the movement, 28 will periodically press the push column 31, and this action will cause the sewage outlet at the bottom of the separation tank 13 to open and close regularly. When the spray chamber 28 applies pressure to the push column 31, the sewage outlet is opened, allowing the sewage and impurities generated during the cleaning process to be discharged smoothly; and when the pressure is released, the rotatable closing disk 33 and the fixed closing disk 34 work closely together to quickly close the sewage outlet, ensuring that the cleaning liquid circulates fully inside the ultrafiltration membrane cartridge 14, and deeply cleans the tiny impurities deposited at the bottom of the pool.

[0066] After this round of efficient cleaning, the cleaning liquid and the impurities it carries will flow through the filter chamber 1. The ultrafiltration membrane here is like a precise screen, intercepting impurities at the bottom of the ultrafiltration membrane cylinder 14 and allowing clean water to pass through; then, simply operate the drain valve at the bottom of the filter chamber 1 to discharge the cleaning liquid accumulated in the filter chamber 1. At the same time, as the spray chamber 28 continues to clean the ultrafiltration membrane cylinder 14, not only can the dirt on the surface of the ultrafiltration membrane be removed, but also the special design of the pressing push column 31 can achieve partial dehydration of the dirt. These preliminarily treated dirt are finally collected in the designated dirt collection bucket 37 for subsequent further processing or safe disposal. The whole process demonstrates the excellent performance of the present invention in terms of cleaning efficiency, degree of automation and resource recovery. Further, the design of the sewage discharge in the present invention can avoid secondary pollution of dirt and ensure the cleaning effect.
