Description

Technical Field

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

[0003] The utility model with the publication number CN214571421U provides a decentralized water purification device coupling electrocatalytic ozone and 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 disk is installed at the bottom. The electrocatalytic ozone unit further 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 disk to disperse the generated ozone gas into the water through the aeration disk. The biological activated carbon unit is filled with activated carbon attached with microorganisms.

[0004] When the water purification device in the above patent is in use, ozone is dispersed into the water through the aeration disk for sterilization and disinfection, and a microcurrent is passed between the anode and cathode by setting the anode and cathode electrodes in cooperation to generate hydrogen peroxide at the cathode. The strongly oxidizing hydroxyl radicals generated by the reaction of hydrogen peroxide and ozone are used for water purification. However, in actual application, the ozone bubbles generated by the aeration disk are large in volume, with a small reaction area in contact with the water body. Moreover, since the bubbles are easily attracted and concentrated and piled up, the dissolution amount of ozone is reduced. Although the anode and cathode electrodes can be used to control the generation of hydroxyl radicals to enhance the disinfection effect, the reaction rate is slow, the number of generated hydroxyl radicals is low, and factors such as current fluctuations, the pH value and temperature of the solution will all affect the reaction. And when the current is too large, side reactions will also occur, resulting in poor water purification stability. Since it is used in remote areas, there are generally more impurities in the water source, and a filtering mechanism needs to be installed at the water inlet to intercept larger impurities. After the filtering mechanism is used for a long time, it needs to be regularly disassembled and cleaned, which is very troublesome, and if the cleaning is not timely, it will affect the water purification transportation efficiency. Summary of the Invention

The electromagnetic ring is electrically connected to the liquid level sensor and repels the elastic magnetic plug when electrified. A through hole is arranged on the outer wall of the upper cavity, and a friction air bag is fixedly connected to the outer periphery of the lower cavity.

[0009] Furthermore, a diversion pipe passing through the lower cavity is fixedly inserted on the outer periphery of the cleaning ring. An inclined downward slope towards the axis is arranged on the inner wall of the cleaning ring. The cleaning ring can sink into the water.

[0010] Furthermore, a sewage discharge groove is arranged between the sealing cover and the upper wall of the filter drum, and a miscellaneous storage cavity is arranged between the sealing cover and the outer wall of the filter drum. A touch switch is fixedly sleeved on the water inlet pipe. The touch switch is movably abutted against the inner wall of the sealing cover. The touch switch is used to control the power-off of the electromagnetic ring. A fixed magnetic ring capable of attracting the electrified electromagnetic ring is fixedly connected to the lower wall of the inner cavity of the sealing cover.

[0011] Further, a driving shaft is rotatably connected to the left end of the biological activated carbon column. The driving shaft is driven by a motor installed on the left side of the biological activated carbon column. A transmission belt is movably sleeved between the driving shaft and the filter drum.

[0012] Further, a first filtering part and a second filtering part are respectively arranged on the upper and lower sides of the filter drum. The first filtering part and the second filtering part are respectively composed of multiple rows of filter holes circumferentially opened on the side wall of the filter drum. The first filtering part faces the spray ring. The liquid level sensor is arranged at a position higher than the first filtering part. The filter holes in the second filtering part are offset from the drain port. The second filtering part is communicated with the water storage cavity.

[0013] Further, the swirling and mixing assembly includes a micro liquid pump circumferentially installed on the upper wall of the water storage cavity. A swirling and mixing tooth tube connected to the output end of the micro liquid pump is rotatably connected to the upper wall of the water storage cavity. The bottom of the inner cavity of the swirling and mixing tooth tube is conical and the upper part is contracted. A tooth ring meshed with the swirling and mixing tooth tube is fixedly connected to the periphery of the filter drum. An ozone generator is fixedly connected to the left wall of the ozone chamber. An air guide pipe is fixedly inserted into the inner wall of the ozone chamber. An air guide cover movably and sealingly sleeved on the swirling and mixing tooth tube is fixedly connected to the outer end of the air guide pipe. One-way air guide grooves communicated with the air guide cover are circumferentially opened on the side wall of the swirling and mixing tooth tube. The one-way air guide grooves are horizontally inclined relative to the axis of the swirling and mixing tooth tube.

[0014] Further, multiple rows of conical atomizing spray holes are circumferentially opened on the inner wall of the spray ring.

[0015] Further, an exhaust water blocking valve passing through the ozone chamber and communicated with the reaction chamber is fixedly inserted into the right wall of the sleeve housing.

[0016] The beneficial effects of the present invention are as follows: When the filter drum performs centrifugal filtration in the present invention, a part of the filtered water is conveyed to the water storage cavity and is controlled by the swirling and mixing assembly to perform swirling reaction with ozone. The ozone is fully dispersed and the contact area with the filtered water is increased, thereby improving its dissolution efficiency. The reaction is sufficient and the water purification effect is good. The purified filtered water is conveyed to the spray ring and is sprayed out by the swinging of the spray ring, colliding with another part of the filtered water output by the rotation of the filter drum. As a result, both parts of the filtered water are cracked into smaller units under the impact, further strengthening the reaction contact area and improving the ozone dissolution efficiency, thereby enhancing the disinfection and purification effect, ensuring stable water purification, and reducing the purification difficulty of the subsequent biological activated carbon column and ultrafiltration base.

[0017] When the filter drum is blocked by impurities and the water inlet pipe still supplies water according to the normal purified water supply volume, the water level in the filter drum continuously rises. When it reaches the liquid level sensor, the cleaning component is automatically controlled to move upward along the inner wall of the filter drum, scraping the impurities upward and pushing them outside the filter drum, so as to clean the impurities in time and ensure stable and efficient water purification.

Detailed Embodiments

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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.

[0021] Embodiment 1, as Figures 1-8As shown in the figure, an integrated water purification device combining ozone, biological activated carbon and ultrafiltration includes an ultrafiltration base 1 and a biological activated carbon column 2 fixedly connected thereto. An 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 expands and drainage 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 assembly for automatically cleaning the inner wall of the filter drum 3 is movably sleeved on the water inlet pipe 4; A casing 6 is fixedly connected to the top of the biological activated carbon column 2 and is movably and sealingly sleeved around the filter drum 3. An ozone chamber 61 is provided on the inner wall of the casing 6. A reaction chamber and a water storage chamber are respectively formed between the casing 6 and the filter drum 3 from top to bottom. An exhaust water-blocking valve 65 passing through the ozone chamber 61 and communicating with the reaction chamber is fixedly inserted into the right wall of the casing 6. A spray ring 73 capable of swinging is rotatably connected to the upper wall of the reaction chamber. A swirl mixing assembly for mixing and conveying 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.

[0022] A water outlet communicating with 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 rotationally and sealingly connected to the middle of the filter drum 3.

[0023] A drive shaft 21 is rotatably connected to the left end of the biological activated carbon column 2. The drive shaft 21 is driven by a motor installed on the left side of the biological activated carbon column 2. A transmission belt is movably sleeved between the drive shaft 21 and the filter drum 3.

[0024] Filtering parts one and two are respectively provided on the upper and lower sides of the filter drum 3. Filtering parts one and two are respectively composed of multiple rows of filter holes circumferentially opened on the side wall of the filter drum 3. Filtering part one is opposite to the spray ring 73. The installation position of the liquid level sensor 31 is higher than that of filtering part one. The filter holes in filtering part two are staggered from the drainage ports. Filtering part two communicates with the water storage chamber.

[0025] When initially used, control the motor to drive the drive shaft 21 and use the transmission belt to drive the filter drum 3 to rotate rapidly at a corresponding rate, and control the water inlet pipe 4 to input the water to be treated into the filter drum 3 through the water outlet. The water passing rate is controlled so that when the first filtering part and the spray ring 73 output normally, the liquid level in the filter drum 3 always remains not exceeding the first filtering part. In the initial stage of water input, under the action of centrifugal force, it is continuously filtered through the second filtering part and thrown into the water storage cavity. As the water is continuously input, the water storage cavity is filled and gradually rises close to the first filtering part. During this period, the flowmeter 41 monitors the water supply. When the incoming water is about to be filtered and thrown out by the first filtering part, the swirling mixing component automatically operates, extracts the water in the water storage cavity and extracts the ozone in the ozone chamber 61, and mixes and reacts the two. The sterilization and disinfection reaction is rapid and sufficient, the water purification effect is good, and the purified filtered water is transported to the spray ring 73 and sprayed out by the swinging of the spray ring 73. Subsequently, the first filtering part just uses centrifugal force to disperse and throw out the filtered water, which collides with the ozone-containing purified water dispersed and output by the spray ring 73, so that the two parts of the filtered water are cracked into smaller units under the impact, further strengthening the reaction contact area and improving the ozone dissolution efficiency, thereby enhancing the disinfection and purification effect. The water after the collision is fully disinfected and purified and then falls to the bottom of the reaction cavity, and is input into the biological activated carbon column 2 through the drain outlets on the front and rear sides of the bottom of the filter drum 3, absorbs pollutants such as organic matter and ammonia nitrogen, and is filtered again by the ultrafiltration base 1 to intercept macromolecular substances such as colloids, bacteria, and viruses in the water. After the water meets the domestic drinking water standard, it is discharged through the water outlet pipe 11. During this period, the exhaust water blocking valve 65 can automatically relieve pressure and exhaust when the internal pressure of the reaction cavity is too high; When a part of the first filtering part or the second filtering part of the filter drum 3 is blocked by impurities and the water inlet pipe 4 still supplies water according to the normal purified water supply volume, since the output of the filter drum 3 decreases, the water surface in the filter drum 3 continuously rises, and when it exceeds the first filtering part and reaches the liquid level sensor 31, the liquid level sensor 31 feeds back to control the cleaning component to automatically operate and move up along the inner wall of the filter drum 3, scraping the impurities upward and pushing them outside the filter drum 3, so as to clean the impurities in time and ensure stable and efficient water purification.

[0026] Embodiment 2, on the basis of the above embodiment, the cleaning component includes a support sleeve 5 slidably sleeved on the water inlet pipe 4. The outer wall of the water inlet pipe 4 is provided with a spiral groove, and the inner wall of the support sleeve 5 is provided with a pin protrusion meshed with the spiral groove. The periphery of the support sleeve 5 is fixedly connected with a cleaning ring 51 with an L-shaped cross section. Two cavities communicating with each other are respectively opened on the upper and lower sides inside the cleaning ring 51. The top of the upper cavity is fixedly connected with an electromagnetic ring 52, and the inner wall is slidably connected with an elastic magnetic plug 53 elastically connected with the electromagnetic ring 52. The electromagnetic ring 52 is electrically connected with the liquid level sensor 31 and repels the elastic magnetic plug 53 when energized. The outer wall of the upper cavity has a through hole, and the periphery of the lower cavity is fixedly connected with a friction airbag 54.

[0027] The initial pin protrusion is snap-connected to 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, facilitating the output of water from both the upper and lower sides of the cleaning ring 51 through the first filtering part. When the liquid level sensor 31 monitors that the water surface in the filter drum 3 is continuously rising and exceeds the first filtering part, the liquid level sensor 31 feeds back to control the energization of the electromagnetic ring 52 to repel the elastic magnetic plug 53 to move downward, thereby pressing the air in the upper cavity into the lower cavity, prompting the friction airbag 54 to expand and abut against the filter drum 3. Since the filter drum 3 is in a rapid rotation state, the support sleeve 5 is driven to rotate rapidly synchronously. Under the limitation of the snap connection between the pin protrusion 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 dredge the first and second filtering parts, ensuring the smooth output of filtered water and achieving efficient water purification.

[0028] Embodiment 3, on the basis of the above embodiment, a diversion pipe 55 passing through the lower cavity is fixedly inserted around the cleaning ring 51, and an inclined downward slope is provided on the inner wall of the cleaning ring 51 in the axial direction, and the cleaning ring 51 can sink into the water.

[0029] When the cleaning ring 51 moves upward, it drives the friction airbag 54 to squeeze the inner wall of the filter drum 3 to scrape and push the impurities upward. When it exceeds the water surface, the diversion pipe 55 can discharge the water between the cleaning ring 51 and the inner wall of the filter drum 3, avoiding taking the water out together and causing an increased subsequent cleaning burden; by using the inclined downward slope provided on the inner wall of the cleaning ring 51 in the axial direction, when the cleaning ring 51 sinks to the bottom, the water supply from the water inlet pipe 4 to the filter drum 3 can form a downward pressure on the cleaning ring 51 by means of the slope, preventing the accidental lifting of the cleaning ring 51 due to the impact of the bottom water flow and resulting in incomplete cleaning of the impurities.

[0030] Embodiment 4, on the basis of the above embodiment, there is a sewage discharge groove between the sealing cover 8 and the upper wall of the filter drum 3, and there is a impurity storage cavity between the sealing cover 8 and the outer wall of the filter drum 3; A touch switch 42 is fixedly sleeved on the water inlet pipe 4, 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 power-off of the electromagnetic ring 52, and a fixed magnetic ring 81 capable of attracting the energized electromagnetic ring 52 is fixedly connected to the lower wall of the inner cavity of the sealing cover 8.

[0031] When the cleaning ring 51 drives the friction airbag 54 to move upward to the sewage discharge groove, the friction airbag 54 disengages from the inner wall of the filter drum 3. However, the cleaning ring 51 still maintains its rotational inertia. And because the fixed magnetic ring 81 attracts the energized electromagnetic ring 52, the upward movement speed of the cleaning ring 51 is thus accelerated, and at the same time, the rotational speed increases. The friction airbag 54 stably scrapes and pushes the impurities at the edge and throws them into the impurity storage cavity through the sewage discharge groove. And when the cleaning ring 51 moves upward to the topmost position, the support sleeve 5 just squeezes the touch switch 42, thereby controlling the electromagnetic ring 52 to cut off the power. The elastic magnetic plug 53 automatically moves upward to reset and drives the friction airbag 54 to contract and recover. Part of the cleaning ring 51 can sink to the bottom of the water again under the action of gravity. Subsequently, the sealing cover 8 can be unscrewed to clean the impurities in the impurity storage cavity, which is convenient and fast.

[0032] Embodiment 5, on the basis of the above embodiments, the swirling and mixing assembly includes a micro liquid pump 7 circumferentially installed on the upper wall of the water storage cavity. The upper wall of the water storage cavity is rotatably connected with a swirling and mixing tooth tube 71 connected to the output end of the micro liquid pump 7. The bottom of the inner cavity of the swirling and mixing tooth tube 71 is conical and the upper part is contracted. A tooth ring 32 meshingly connected with the swirling and mixing tooth tube 71 is fixedly connected to the periphery of the filter drum 3; The left wall of the ozone chamber 61 is fixedly connected with an ozone generator 62. A gas guide tube 63 is fixedly inserted into the inner wall of the ozone chamber 61. The outer end of the gas guide tube 63 is fixedly connected with a gas guide hood 64 movably and sealingly sleeved on the swirling and mixing tooth tube 71. A one-way gas guide groove communicating with the gas guide hood 64 is circumferentially formed on the side wall of the swirling and mixing tooth tube 71. The one-way gas guide groove is horizontally inclined relative to the axis of the swirling and mixing tooth tube 71.

[0033] At the initial stage of water purification, when the flowmeter 41 monitors that the water volume input into the filter drum 3 and the water storage cavity is sufficient, the flowmeter 41 feeds back to control the micro liquid pump 7 to operate, pumping out the filtered water in the water storage cavity and pressing it into the swirling and mixing tooth tube 71. Since the bottom of the inner cavity of the swirling and 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 a negative pressure is formed inside it, so that the ozone gas in the ozone chamber 61 is automatically inhaled through each one-way gas guide groove. And because the one-way gas guide groove is horizontally inclined relative to the axis of the swirling and mixing tooth tube 71, the ozone in each one-way gas guide groove is thus inclined and inhaled into the swirling and mixing tooth tube 71, thus automatically realizing swirling flow. Moreover, since the filter drum 3 drives the swirling and mixing tooth tube 71 to rotate at high speed by using the tooth ring 32 when rotating, the ozone and the filtered water rotate at high speed after mixing. Under the action of the speed difference and shear force, they are repeatedly dispersed and mixed, and the degree of turbulence is increased. The larger ozone bubbles are automatically cracked into a large number of microbubbles, and the ozone is fully dispersed, increasing the contact area with the filtered water, thereby improving the dissolution efficiency of ozone and enhancing its sterilization and disinfection effect.

[0034] Embodiment Six. On the basis of the above embodiments, multiple rows of conical atomizing spray holes are formed in the inner circumference of the inner wall of the spray ring 73. A torsion spring 74 is fixedly connected between the spray ring 73 and the inner wall of the housing 6. On one side of the bottom of the spray ring 73 close to the swirl mixing tooth tube 71, a circumferentially arrayed inclined plate 75 is fixedly connected. An abutting plate 72 capable of extruding the inclined plate 75 is fixedly connected to the outer wall of the swirl mixing tooth tube 71. The bottom of the inner cavity of the spray ring 73 is rotationally and sealingly connected with a sealing ring plate 76, and the swirl mixing tooth tube 71 is rotationally and sealingly connected to the sealing ring plate 76.

[0035] When the ozone-sterilized and disinfected filtered water is output to the spray ring 73 through the high-speed rotation of the swirl mixing tooth tube 71, the spray ring 73 can relatively atomize and spray the filtered water after sterilization and disinfection by using the conical atomizing spray holes. During this period, the swirl mixing tooth tube 71 drives the abutting plate 72 to intermittently extrude the inclined plate 75, so as to drive the spray ring 73 to reciprocate and deflect and swing to spray the filtered water with the recovery performance of the torsion spring 74, 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 deflects, and the supply of the filtered water to the spray ring 73 is stable. Synchronously, since the first filter part on the filter drum 3 rotates and sprinkles the filtered water towards the spray ring 73 at the same time, the output filtered water is also relatively atomized and dispersed based on the rotational force, and the two are opposed to each other, so that the two parts of the filtered water are further cracked into smaller units by the impact, further increasing the contact reaction area between them, increasing the ozone solubility, and the unreacted ozone output from the spray ring 73 can also further react with the mixed atomized filtered water again, increasing the ozone consumption and avoiding discharging to the outside.

[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
