Description

Technical Field

[0001] The present invention relates to the technical field of water purification equipment, and in particular to an ozone-biological activated carbon combined with ultrafiltration integrated water purification device. Background Art

[0002] The utility model with publication number CN214571421U provides a decentralized water purification device of electrocatalytic ozone coupled with biological activated carbon. The device includes an electrocatalytic ozone unit, a biological activated carbon unit and a water storage unit arranged in sequence from top to bottom; at least two pairs of electrodes are installed in the electrocatalytic ozone unit, and an aeration plate is installed at the bottom; the electrocatalytic ozone unit also includes a DC power supply and an ozone generator, the DC power supply is electrically connected to the electrodes to supply power to the electrodes, and the ozone generator is connected to the aeration plate to disperse the generated ozone gas into the water through the aeration plate; the biological activated carbon unit is filled with activated carbon with attached microorganisms.

[0003] When in use, the water purification device of the above-mentioned patent disperses ozone into water through an aeration disk for sterilization and disinfection. A microcurrent is controlled by setting up anode and cathode electrodes to pass between the cathode and cathode electrodes, thereby generating hydrogen peroxide at the cathode. The water is purified by utilizing the highly oxidizing hydroxyl radicals generated by the reaction of hydrogen peroxide and ozone. However, in actual use, the ozone bubbles generated by the aeration disk are large in volume, and the reaction area in contact with the water is small. In addition, the bubbles are easily attracted and concentrated, thereby reducing the amount of ozone dissolved. Although the generation of hydroxyl radicals to enhance the disinfection effect can be controlled by the cathode and cathode electrodes, the reaction rate is slow and the number of hydroxyl radicals generated is low. Moreover, current fluctuations, the pH value and temperature of the solution can all affect the reaction. Excessive current can also cause side reactions, resulting in poor water purification stability. Since the water source is generally rich in impurities, a filter mechanism needs to be installed at the water inlet to intercept larger impurities. The filter mechanism needs to be regularly disassembled and cleaned after long-term use, which is very troublesome. In addition, untimely cleaning can also affect the water purification delivery efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] Example 1, as Figures 1-8 As shown, an ozone-biological activated carbon combined with ultrafiltration integrated water purification device includes an ultrafiltration base 1 and a biological activated carbon column 2 fixedly connected thereto. A water outlet pipe 11 is provided on the right side of the ultrafiltration base 1. The upper end of the biological activated carbon column 2 is rotatably connected to a filter drum 3 with an open top. A liquid level sensor 31 is provided on the inner wall of the filter drum 3. The bottom of the filter drum 3 is expanded and drain ports are provided on both the front and rear sides. A water inlet pipe 4 is provided in the middle of the filter drum 3. A flow meter 41 is provided on the inner wall of the water inlet pipe 4. A cleaning component for automatically cleaning the inner wall of the filter drum 3 is movably sleeved on the water inlet pipe 4.

[0033] The top of the biological activated carbon column 2 is fixedly connected to a casing 6 that is movably sealed and sleeved on the periphery of the filter drum 3. The inner wall of the casing 6 has an ozone chamber 61. A reaction chamber and a water storage chamber are formed between the casing 6 and the filter drum 3 from top to bottom. An exhaust water-blocking valve 65 that passes through the ozone chamber 61 and is connected to the reaction chamber is fixedly connected to the right wall of the casing 6. A swingable spray ring 73 is rotatably connected to the upper wall of the reaction chamber. A rotary mixing component for mixing and transporting ozone and water to the spray ring 73 is provided between the ozone chamber 61 and the water storage chamber. A sealing cover 8 is threadedly connected to the top of the casing 6.

[0034] A water outlet connected to the inner cavity of the filter drum 3 is provided at the bottom of the water inlet pipe 4 . The water inlet pipe 4 is fixedly connected to the upper end of the biological activated carbon column 2 , and is rotatably and sealedly connected to the middle of the filter drum 3 .

[0035] The left end of the biological activated carbon column 2 is rotatably connected to a drive shaft 21 , which is driven by a motor installed on the left side of the biological activated carbon column 2 , and a transmission belt is movably connected between the drive shaft 21 and the filter drum 3 .

[0036] Filter part 1 and filter part 2 are respectively provided on the upper and lower sides of the filter drum 3. Filter part 1 and filter part 2 are respectively composed of multiple rows of filter holes circumferentially opened on the side wall of the filter drum 3. Filter part 1 is opposite to the spray ring 73. The liquid level sensor 31 is arranged at a position higher than filter part 1. The filter holes in filter part 2 are staggered with the drain outlet, and filter part 2 is connected to the water storage chamber.

[0037] During initial use, the motor is controlled to drive the drive shaft 21 and use the transmission belt to drive the filter drum 3 to rotate rapidly at a corresponding speed, and the water inlet pipe 4 is controlled to use the water outlet to input the water to be treated into the filter drum 3. When the water flow rate is controlled at the normal output of the filter part 1 and the spray ring 73, the liquid level in the filter drum 3 is always kept within the filter part 1. In the initial stage of water input, under the action of centrifugal force, the water is continuously filtered and thrown into the water storage chamber through the filter part 2. With continuous input, the water storage chamber is filled and gradually rises to approach the filter part 1. During this period, the flow meter 41 monitors the water supply. When the supplied water is about to be filtered and thrown out by the filter part 1, the rotary mixing component automatically runs to extract the water in the water storage chamber and extract the ozone in the ozone chamber 61 to perform a rotary mixing reaction between the two. The sterilization reaction is fast and sufficient, and the water purification effect is good. The purified filtered water is output It is sent to the spray ring 73 and sprayed out by the swing of the spray ring 73. Then, the filter part uses centrifugal force to disperse and throw out the filtered water, which impacts the ozone-containing purified water dispersedly output by the spray ring 73, so that the two parts of filtered water are broken into smaller units by the impact, further enhancing the reaction contact area and improving the ozone dissolution efficiency, thereby enhancing the disinfection and purification effect. The water after the flushing is fully disinfected and purified and falls into the bottom of the reaction chamber. It is input into the biological activated carbon column 2 through the drainage ports on the front and back sides of the bottom of the filter drum 3 to absorb pollutants such as organic matter and ammonia nitrogen, and is filtered again by the ultrafiltration base 1 to intercept colloids, bacteria, viruses and other macromolecular substances in the water. After the water meets the standards for drinking water, it is discharged through the outlet pipe 11. During this period, the exhaust water blocking valve 65 can automatically relieve the pressure and exhaust when the pressure inside the reaction chamber is too high;

[0038] When the filter part 1 or the filter part 2 of the filter drum 3 is clogged by impurities and the water inlet pipe 4 still takes in water according to the normal purified water supply, the output of the filter drum 3 decreases, and the water level in the filter drum 3 continues to rise. When it exceeds the filter part 1 and reaches the liquid level sensor 31, the liquid level sensor 31 feedback controls the cleaning component to automatically move upward along the inner wall of the filter drum 3, scraping the impurities upward to the outside of the filter drum 3, thereby cleaning the impurities in time and ensuring stable and efficient water purification.

[0039] Example 2, on the basis of the above example, the cleaning component includes a support sleeve 5 that is slidably sleeved on the water inlet pipe 4, the outer wall of the water inlet pipe 4 is provided with a spiral groove, the inner wall of the support sleeve 5 is provided with a pin protrusion that engages with the spiral groove, the outer periphery of the support sleeve 5 is fixedly connected to a cleaning ring 51 with an L-shaped cross-section, the upper and lower sides of the interior of the cleaning ring 51 are respectively provided with two connected cavities, the top of the upper cavity is fixedly connected to an electromagnetic ring 52, and the inner wall is slidably connected to an elastic magnetic plug 53 elastically connected to the electromagnetic ring 52, the electromagnetic ring 52 is electrically connected to the liquid level sensor 31 and is energized to repel the elastic magnetic plug 53, the outer wall of the upper cavity has a through hole, and the outer periphery of the lower cavity is fixedly connected to a friction airbag 54.

[0040] Initially, the pin convex is engaged with the bottom of the spiral groove, and there is a gap between the bottom of the cleaning ring 51 and the lower wall of the inner cavity of the filter drum 3, so that water can be output from the upper and lower sides of the cleaning ring 51 through the filter part 1. When the liquid level sensor 31 detects that the water level in the filter drum 3 is constantly rising and exceeds the filter part 1, the liquid level sensor 31 feedback controls the electromagnetic ring 52 to energize and repel the elastic magnetic plug 53 to move downward, thereby pressing the air in the upper cavity into the lower cavity, causing the friction airbag 54 to expand and abut against the filter drum 3. Since the filter drum 3 is in a fast-rotating state, the support sleeve 5 is synchronously driven to rotate rapidly. Under the restriction of the engagement of the pin convex and the spiral groove, the cleaning ring 51 and the support sleeve 5 climb along the water inlet pipe 4, and the friction airbag 54 is driven to scrape and push the blocked impurities upward to clear the filter parts 1 and 2, ensuring smooth output of filtered water and achieving efficient water purification.

[0041] Embodiment 3: Based on the above embodiment, a guide tube 55 passing through the lower cavity is fixedly inserted on the periphery of the cleaning ring 51, and the inner wall of the cleaning ring 51 is provided with a slope inclined downward toward the axis, so that the cleaning ring 51 can sink into water.

[0042] The cleaning ring 51 moves upward to drive the friction airbag 54 to squeeze the inner wall of the filter drum 3 to scrape the impurities upward. When it exceeds the water surface, the guide pipe 55 can discharge the water between the cleaning ring 51 and the inner wall of the filter drum 3 to avoid carrying out the water together, which will increase the subsequent cleaning burden. The inner wall of the cleaning ring 51 is provided with a slope inclined downward in the axial direction. When the cleaning ring 51 sinks to the bottom, the water inlet pipe 4 supplies water to the filter drum 3 and can use the slope to form a downward pressure on the cleaning ring 51, thereby avoiding the impact of the bottom water flow causing the cleaning ring 51 to be accidentally lifted, resulting in an inability to completely clean the impurities.

[0043] Embodiment 4, based on the above embodiment, a sewage drain groove is provided between the sealing cover 8 and the upper wall of the filter drum 3, and a storage cavity is provided between the sealing cover 8 and the outer wall of the filter drum 3;

[0044] A touch switch 42 is fixedly sleeved on the water inlet pipe 4, and the touch switch 42 is movably abutted against the inner wall of the sealing cover 8. The touch switch 42 is used to control the electromagnetic ring 52 to cut off the power. A fixed magnetic ring 81 that can attract the energized electromagnetic ring 52 is fixedly connected to the lower wall of the inner cavity of the sealing cover 8.

[0045] When the cleaning ring 51 drives the friction airbag 54 to move up to the sewage trough, the friction airbag 54 is separated from the inner wall of the filter drum 3, but the cleaning ring 51 still maintains the rotational inertia, and because the fixed magnetic ring 81 attracts the energized electromagnetic ring 52, the upward speed of the cleaning ring 51 is accelerated, and the rotation speed is increased. The friction airbag 54 stably pushes the impurities scraped from the edge through the sewage trough into the storage chamber, and when the cleaning ring 51 moves to the top, the support sleeve 5 just squeezes the touch switch 42, thereby controlling the electromagnetic ring 52 to cut off the power, and the elastic magnetic plug 53 automatically moves up and resets and drives the friction airbag 54 to shrink and recover. The cleaning ring 51 part can sink to the bottom of the water again under the action of gravity, and the sealing cover 8 can be unscrewed later to clean out the impurities in the storage chamber, which is convenient and quick.

[0046] Example 5, based on the above example, the mixing assembly includes a micro-liquid pump 7 circumferentially mounted on the upper wall of the water storage chamber. The upper wall of the water storage chamber is rotatably connected to a mixing tooth tube 71 connected to the output end of the micro-liquid pump 7. The bottom of the inner cavity of the mixing tooth tube 71 is conical and the upper part is contracted. The outer periphery of the filter drum 3 is fixedly connected to a gear ring 32 meshing with the mixing tooth tube 71.

[0047] An ozone generator 62 is fixedly connected to the left wall of the ozone chamber 61, an air guide tube 63 is fixedly inserted into the inner wall of the ozone chamber 61, and the outer end of the air guide tube 63 is fixedly connected to an air guide cover 64 that is movably sealed and sleeved on the mixing tooth tube 71. A one-way air guide groove is opened on the circumference of the side wall of the mixing tooth tube 71 and is connected to the air guide cover 64. The one-way air guide groove is horizontally inclined relative to the axis of the mixing tooth tube 71.

[0048] At the beginning of water purification, when the flow meter 41 detects that the amount of water input to the filter drum 3 and the water storage chamber is sufficient, the flow meter 41 feedback controls the micro liquid pump 7 to operate to extract the filtered water in the water storage chamber and pressurize it into the vortex mixing tooth tube 71. Since the bottom of the inner cavity of the vortex mixing tooth tube 71 is conical and the upper part is contracted, the flow rate of the filtered water is accelerated when passing through the contraction section, and negative pressure is formed inside, thereby automatically sucking the ozone gas in the ozone chamber 61 through each one-way air guide groove. Since the one-way air guide groove is horizontally inclined relative to the axis of the vortex mixing tooth tube 71, each The ozone in the one-way air guide groove is thus obliquely sucked into the vortex mixing tooth tube 71, thereby automatically realizing vortex flow. Moreover, since the vortex mixing tooth tube 71 is driven by the gear ring 32 to rotate at high speed when the filter drum 3 rotates, the ozone and the filtered water are mixed and rotated at high speed. Under the action of the speed difference and shear force, they are repeatedly dispersed and mixed, and the turbulence level is increased. The larger ozone bubbles are automatically broken down into a large number of microbubbles. The ozone is fully dispersed, and the contact area between the ozone and the filtered water is increased, thereby improving the dissolution efficiency of the ozone and enhancing its sterilization and disinfection effect.

[0049] Example 6. On the basis of the above-mentioned example, a plurality of rows of conical atomizing spray holes are provided on the inner circumference of the spray ring 73. A torsion spring 74 is fixedly connected between the spray ring 73 and the inner wall of the casing 6. A circumferential array of inclined plates 75 is fixedly connected to the side of the bottom of the spray ring 73 close to the rotary mixing tooth tube 71. A stop plate 72 capable of squeezing the inclined plate 75 is fixedly connected to the outer wall of the rotary mixing tooth tube 71. A sealing ring plate 76 is rotatably sealed and connected to the bottom of the inner cavity of the spray ring 73. The rotary mixing tooth tube 71 is rotatably sealed and connected to the sealing ring plate 76.

[0050] When the filtered water sterilized by ozone is output to the spray ring 73 through the high-speed rotation of the rotary mixing tooth tube 71, the spray ring 73 can relatively atomize and spray the sterilized filtered water using the conical atomizing nozzle. During this period, the rotary mixing tooth tube 71 drives the abutment plate 72 to intermittently squeeze the inclined plate 75, thereby cooperating with the recovery performance of the torsion spring 74 to drive the spray ring 73 to reciprocate and swing to spray the filtered water, and the atomization effect is better. During this period, the sealing ring plate 76 is used to ensure that the filtered water will not leak when the spray ring 73 is deflected, and the filtered water supply to the spray ring 73 is stable. Synchronously, due to the simultaneous rotation of the filter part on the filter drum 3, the filtered water is thrown toward the spray ring 73. The output filtered water is also relatively atomized and dispersed based on the rotational force. The two offset each other, so that the two parts of the filtered water are further decomposed into smaller units by the impact, further increasing the contact reaction area between each other and improving the ozone solubility. In addition, the ozone output from the spray ring 73 that has not completely reacted can also further react with the mixed atomized filtered water again, increasing ozone consumption and avoiding discharge.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
