Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of self-cleaning separation equipment, in particular to a horizontal self-cleaning filter with backwashing. BACKGROUND

[0002] In the fields of industrial production, municipal water supply and drainage, farmland irrigation, circulating water treatment, etc., the fluid often contains suspended particles, colloids, fibers, silt and other impurities. If effective filtration is not performed, it will lead to pipe blockage, equipment wear, product quality decline, and even system failure. Therefore, the fluid filtration equipment is the core auxiliary equipment in various fluid conveying and processing systems.

[0003] The patent with patent announcement number CN217472809U includes a filter tank, a water inlet pipe, a water suction pipe, a sewage discharge pipe, a motor, a stirring rod, a filter plate, a cleaning mechanism including a first connecting pipe, and a shielding mechanism. By setting the shielding mechanism, the external water pipe can be twisted to the inside of the first connecting pipe when washing the filter plate. During this process, the external water pipe pushes the block to the inside of the second connecting pipe. At this time, the extension spring contracts, so that the external water flow enters the inside of the second connecting pipe and is sprayed from the bottom of the spray pipe. After cleaning is completed, the external water pipe can be removed. At this time, the extension spring returns to its original position, so that the block is pushed to the top of the first connecting pipe by the T-shaped rod to shield, thereby saving a lot of time and providing convenience for subsequent use.

[0004] Although the above-mentioned patent can improve the water flow filtration efficiency to some extent, save operation time, and provide convenience for subsequent use, it still has obvious technical defects. In the process of long-term continuous filtration of sewage, suspended particles, colloids and fiber impurities in the sewage are easily attached and accumulated on the surface of the filter assembly, thereby blocking the filter holes of the filter assembly, increasing the filtration resistance of the equipment, and continuously reducing the filtration effect, making it difficult to ensure long-term stable filtration conditions.

[0010] The smoothing plate and the eccentric wheel are in contact with each other, the cleaning plate and the activated carbon plate are in contact with each other, the hollow plate and the sliding frame are in contact with each other, and the surface of the fixed rod is provided with a spring.

[0011] The scraping mechanism comprises a condensing mechanism mounted on the outer rotating plate, the condensing mechanism comprising a storage tank mounted on the shell, a hollow frame mounted on the buffer plate, a rounded plate mounted on the outer rotating plate, a sliding rod mounted on the hollow frame, a moving rod mounted on the hollow frame, an L-shaped sealing plate mounted on the shell, a trapezoidal block mounted on the moving rod, and a triangular block mounted on the sliding rod, the triangular block being pushed to move by the extrusion force.

[0012] The condensing mechanism further comprises a rounded plate mounted on the rotating plate, an elastic rod mounted on the rounded plate, an inclined block mounted on the filter cartridge, and a rounded block mounted on the elastic rod. Wherein, a spring is arranged between the rounded block and the rounded plate, and the rounded block is used to vibrate the filter cartridge.

[0013] The inclined block and the rounded block are in contact with each other, the moving rod is fixedly connected with the L-shaped sealing plate, the triangular block and the trapezoidal block are in contact with each other, and the rounded plate and the outer rotating plate are in contact with each other.

[0014] Compared with the prior art, the beneficial effects of the present application are: 1、In the process of filtering sewage, the sewage is first blocked by the buffer plate for buffering, preventing large particles in the water flow from directly impacting the filter cartridge, thereby protecting the filter cartridge from damage and deformation, prolonging the service life of the filter cartridge, and starting the backwashing mode for deep cleaning after the filter runs for a period of time. At this time, the filter stops filtering, and during cleaning, the suction scanner can evenly clean the inside of the filter cartridge, preventing impurities from being left behind, further eliminating cleaning dead angles, completely solving the problem of local dirt accumulation, and simultaneously scraping off the particle impurities embedded inside the mesh and attached to the inner and outer surfaces of the filter screen, effectively unblocking the blocked mesh, avoiding hole shrinkage and plugging, maintaining the permeability of the filter cartridge for a long time, maintaining the constant filtration flow of the equipment, preventing impurities from being dry and hard on the surface of the filter cartridge, slowing down the corrosion and aging rate of the filter cartridge, and during the process of treating impurities, the brush plate rotates to further contact the inner wall of the filter cartridge, and can contact the protrusions of the sand, so as to brush off the sand stuck in the pores of the filter cartridge, restore the effective water passage area of the filter cartridge, avoid flow attenuation caused by pore blockage, further ensure that the filter maintains the rated water passage flux for a long time, and real-time cleaning of pore sand embedding can be realized for harsh working conditions such as river water, circulating water, and farmland irrigation water with high sand content, avoiding sand accumulation vicious cycle, making the horizontal self-cleaning filter adapt to more complex water quality scenes, and greatly improving the running stability.

[0015] 2. In this invention, when treating impurities, it adsorbs odors, color, and organic pollutants in the water, and further traps fine particles and colloidal impurities, improving the filtration accuracy of wastewater. Simultaneously, it adsorbs emulsified oil, floating oil, and oily colloids in the water, preventing oil stains from adhering to the filter screen and forming an oil film, thus reducing the clogging rate of the filter cartridge. The rotation of the activated carbon plate increases its contact area with the water flow, significantly improving the adsorption and purification efficiency of odors, color, organic matter, and fine colloids in the water. It also creates moderate disturbance to the water flow inside the cartridge, breaking the static laminar flow phenomenon, allowing the water to fully contact the activated carbon micropores, preventing short-circuiting of the water flow, and improving the removal effect of odors and discoloration. When adsorbing odors, the cleaning plate moves downwards and contacts the surface of the activated carbon plate, brushing off fine impurities adhering to the surface of the activated carbon plate, preventing impurities from clogging the activated carbon micropores, preventing the adsorption channels from becoming blocked, and thus maintaining the adsorption and purification effect of activated carbon on odors, color, organic matter, and fine colloids in the water.

[0016] 3. In this invention, during the backwashing process, tiny colloids, suspended particles, and fine silt in the water can be agglomerated into large flocs, effectively trapping fine impurities that could originally penetrate the filter cartridge. This compensates for the insufficient screening precision of the filter cartridge, significantly improving the effluent purification effect. Simultaneously, it allows for intermittent discharge of chemicals, preventing excessive discharge and waste caused by long-term continuous chemical dosing, reducing chemical usage costs and operating expenses. It also prevents excessive chemical use and secondary water pollution. During backwashing, the elastic rod is reset by a spring and generates an impact force on the filter cartridge, actively shaking off silt, suspended debris, oil, and flocs adhering to the filter cartridge surface. This prevents long-term accumulation of impurities, reduces the surface contamination load of the filter cartridge, assists backwashing, and enhances the self-cleaning effect.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1:

[0021] Please see Figures 1-6 One embodiment of the present invention is: a horizontal self-cleaning filter with backwashing, comprising a housing 1, an inlet 2 mounted on the housing 1, an outlet 3 mounted on the housing 1, a servo motor 4 mounted on the housing 1, and an output shaft 5 mounted on the output end of the servo motor 4. The horizontal self-cleaning filter with backwashing further includes: A filtration mechanism, installed on the housing 1, is used to filter impurities in the water; A scraping mechanism, installed on the filtration mechanism, is used to improve the filtration efficiency of wastewater; An anti-clogging mechanism, installed on the output shaft 5, is used to prevent a decrease in filtration efficiency and avoid sewage blockage.

[0022] The filtration mechanism includes a filter cartridge 6 mounted on the housing 1 and a suction scanner 7 mounted on the output shaft 5. The filter cartridge 6 is used to perform preliminary filtration of impurities in the water. A buffer plate 18 is installed on the housing 1 to relieve the pressure of sewage and prevent large particles of impurities in the water flow from directly impacting the filter cartridge 6. The scraping mechanism includes a rotating plate 8 mounted on the output shaft 5, which rotates when the output shaft 5 rotates, a scraping plate 9 mounted on the rotating plate 8, a three-plate ring 10 mounted on the output shaft 5, and an outer rotating plate 11 mounted on the three-plate ring 10. The scraping plate 9 is used to treat impurities on the inner wall of the filter cylinder 6, and the outer rotating plate 11 is used to treat impurities on the outer wall of the filter cylinder 6. When the three-plate ring 10 rotates, it will drive the outer rotating plate 11 to rotate. In this embodiment, during wastewater filtration, water flows into the interior of the outer casing 1 through inlet 2 and then through filter cylinder 6. During filtration, coarse particles in the water are intercepted on the surface of filter cylinder 6. Simultaneously, as the wastewater enters the outer casing 1, it is first buffered by buffer plate 18 to prevent large particles from directly impacting filter cylinder 6, thus protecting it from damage and deformation, and extending its service life. After passing through the coarse filter screen on the left side of filter cylinder 6, the water enters the fine filter screen on the right side for further filtration. The filtered water is then discharged through outlet 3. After the filter has been running for a period of time, a backwash mode is activated for deep cleaning. At this time, the filter stops filtering, and the liquid inside the outer casing 1 is discharged through the drain port at the bottom of the outer casing 1. When the pressure difference between the inside and outside of the filter reaches a set value, a self-cleaning mode is activated. The drain valve connected to the drain pipe opens, and negative pressure is generated inside the suction nozzle of the suction scanner 7 to suck up impurities. During cleaning, the servo motor... 4. The start-up mechanism will drive the output shaft 5 to rotate, which in turn will drive the suction scanner 7 to rotate, enabling the suction scanner 7 to evenly clean the inside of the filter cartridge 6 and prevent impurities from remaining. At the same time, the rotation of the output shaft 5 will drive the three-plate ring 10 to rotate, which in turn will drive the outer rotating plate 11 to rotate. During the rotation of the outer rotating plate 11, it will contact the outer surface of the filter cartridge 6 and scrape off the impurities attached to the outer surface. Simultaneously, the rotation of the output shaft 5 will also drive the rotating plate 8 to rotate, which will drive the scraping plate 9 to rotate and process fine particulate impurities on the inner wall of the filter cartridge 6. This will further eliminate cleaning dead corners and thoroughly solve the problem of localized dirt accumulation and residue. It can also simultaneously scrape off particulate debris embedded in the mesh and attached to the inner and outer surfaces of the filter screen, effectively unclogging the mesh, preventing the holes from narrowing and blocking, maintaining the permeability of the filter cartridge 6 for a long time, maintaining a constant filtration flow rate of the equipment, preventing impurities from drying and hardening on the surface of the filter cartridge 6 for a long time, and slowing down the corrosion and aging rate of the filter cartridge 6.

[0023] The anti-clogging mechanism includes a perforated plate 12 mounted on the output shaft 5, a rotating rod 13 rotating during the rotation of the perforated plate 12, a rotating rod 13 mounted on the perforated plate 12, a transmission wheel 14 mounted on the rotating rod 13, and a brush plate 15 mounted on the rotating rod 13. During operation, the transmission wheel 14 rotates due to the friction between itself and the filter cylinder 6. The brush plate 15 is used to treat impurities in the pores of the filter cylinder 6. During the rotation of the brush plate 15, it will further contact the inner wall of the filter cylinder 6.

[0024] The scraper plate 9 is in contact with the filter cylinder 6, the outer rotating plate 11 is in contact with the filter cylinder 6, and the filter cylinder 6 is in contact with the drive wheel 14.

[0025] During the impurity treatment process, the rotation of the output shaft 5 synchronously drives the perforated plate 12 to rotate. The rotation of the perforated plate 12 drives the rotating rod 13 to rotate, which in turn drives the transmission wheel 14 to rotate. The transmission wheel 14 comes into contact with the filter cylinder 6 during rotation, generating friction that forces the transmission wheel 14 to rotate. The rotation of the transmission wheel 14 drives the rotating rod 13 to rotate, which in turn drives the brush plate 15 to rotate. The brush plate 15 further contacts the inner wall of the filter cylinder 6 and the protrusions of the sand and gravel, thereby brushing off the sand and gravel stuck in the pores of the filter cylinder 6, restoring the effective water flow area of ​​the filter cylinder 6, avoiding flow reduction due to pore blockage, and further ensuring that the filter maintains its rated water flow rate for a long time. For harsh working conditions with high sand content, such as river water, circulating water, and farmland irrigation water, it can clean the sand embedded in the pores in real time, avoiding the vicious cycle of sand accumulation, making the horizontal self-cleaning filter adaptable to more complex water quality scenarios, and greatly improving operational stability.

[0026] Example 2:

[0027] Please see Figures 7-8 Based on the above embodiments, in another embodiment of the present invention, the anti-clogging mechanism includes an adsorption mechanism 16 installed on the perforated plate 12. The adsorption mechanism 16 includes a rotating plate 161 installed on the output shaft 5 and an activated carbon plate 162 installed on the rotating plate 161. The rotation of the rotating plate 161 will drive the activated carbon plate 162 to rotate. The activated carbon plate 162 is used to adsorb impurities in sewage.

[0028] The anti-clogging mechanism also includes an eccentric wheel 163 mounted on a rotating rod 13, which rotates when the rotating rod 13 rotates, a fixed rod 164 mounted on a perforated plate 12, a sliding frame 165 mounted on the fixed rod 164, a support plate 166 mounted on the sliding frame 165, a cleaning plate 167 mounted on the sliding frame 165, and a smooth plate 168 mounted on the support plate 166. The cleaning plate 167 is used to improve the adsorption effect of the activated carbon plate 162, and the eccentric wheel 163 is used to apply pressure to the smooth plate 168, forcing the smooth plate 168 to move downward.

[0029] The smooth plate 168 is in contact with the eccentric wheel 163, the cleaning plate 167 is in contact with the activated carbon plate 162, the hollow plate 12 is in contact with the sliding frame 165, and the sliding frame 165 will drive the cleaning plate 167 to move downward when it moves downward. The surface of the fixing rod 164 is provided with a spring.

[0030] In this embodiment, during impurity treatment, the rotation of output shaft 5 drives the rotation of rotating plate 161, which in turn drives the rotation of activated carbon plate 162. This adsorbs odors, color, and organic pollutants in the water, and further traps fine particles and colloidal impurities, improving the filtration accuracy of wastewater. Simultaneously, it adsorbs emulsified oil, floating oil, and oily colloids in the water, preventing oil from adhering to the filter screen and forming an oil film, thus reducing the clogging rate of filter cartridge 6. Furthermore, the rotation of activated carbon plate 162 increases its contact area with the water flow, significantly improving the adsorption and purification efficiency of odors, color, organic matter, and fine colloids in the water. It also creates moderate disturbance to the water flow inside the cartridge, breaking the static laminar flow phenomenon and ensuring full contact between the water and the micropores of the activated carbon, preventing short-circuiting of the water flow and improving the removal effect of odors and discoloration. During odor adsorption… The rotation of the rotating rod 13 drives the eccentric wheel 163 to rotate. The rotation of the eccentric wheel 163 compresses the smooth plate 168 through the protrusions on its surface, forcing the smooth plate 168 to move downward. The downward movement of the smooth plate 168 drives the support plate 166 to move downward. The downward movement of the support plate 166 drives the sliding frame 165 to move downward. During the downward movement of the sliding frame 165, it compresses the spring set on the surface of the fixing rod 164. When the sliding frame 165 moves downward, it drives the cleaning plate 167 to move downward. When the cleaning plate 167 moves downward, it comes into contact with the surface of the activated carbon plate 162, thereby brushing off the fine impurities attached to the surface of the activated carbon plate 162, preventing impurities from blocking the micropores of the activated carbon, preventing the adsorption channels from being blocked, and thus maintaining the adsorption and purification effect of activated carbon on water odors, color, organic matter and fine colloids.

[0031] Example 3:

[0032] Please see Figures 8-11Based on the above embodiments, in another embodiment of the present invention, the scraping mechanism includes a condensation mechanism 17 mounted on the outer rotating plate 11. The condensation mechanism 17 includes a storage tank 171 mounted on the outer shell 1, a hollow frame 172 mounted on the buffer plate 18, a rounded plate 173 mounted on the outer rotating plate 11, the rounded plate 173 contacting the sliding rod 174 during rotation, the sliding rod 174 mounted on the hollow frame 172, the moving rod 175 mounted on the hollow frame 172, the moving rod 175 moving to the right when the trapezoidal block 177 moves to the right, an L-shaped sealing plate 176 mounted on the outer shell 1, the trapezoidal block 177 mounted on the moving rod 175, and a triangular block 178 mounted on the sliding rod 174. During the movement of the triangular block 178, it generates a squeezing force on the trapezoidal block 177, and the triangular block 178 will push the trapezoidal block 177 to move through the squeezing force.

[0033] In this embodiment, during backwashing, the outer rotating plate 11 rotates, causing the rounded plate 173 to rotate as well. During this rotation, the rounded plate 173 contacts the sliding rod 174 and, through pressure, pushes the sliding rod 174 upwards, which in turn pushes the triangular block 178 to move synchronously. The triangular block 178 exerts pressure on the trapezoidal block 177, pushing it to the right. This movement of the trapezoidal block 177 to the right causes the moving rod 175 to move to the right. The movement of the moving rod 175 then moves the L-shaped sealing plate 176. When the L-shaped sealing plate 176 moves, it closes the drain outlet of the storage tank 171. When the rounded plate 173 and the sliding rod 174 are no longer in contact, the sliding rod 174... The device will move downwards under gravity. At this time, the moving rod 175 will be reset by the surface spring and move to the left, thereby opening the drain port of the storage tank 171. At the same time, the water pump inside the storage tank 171 will start and spray the flocculant stored inside into the interior of the outer shell 1. This will agglomerate the tiny colloids, suspended particles, and fine silt in the water into large flocs, effectively trapping the fine impurities that could originally penetrate the filter cylinder 6. This compensates for the insufficient screening precision of the filter cylinder 6, significantly improving the effluent purification effect. It can also intermittently discharge the agent, avoiding excessive discharge and waste caused by long-term continuous dosing of the agent, reducing the cost of agent use and operating expenses, and preventing excessive agent use and secondary pollution of the water.

[0034] The condensation mechanism 17 also includes a rounded corner plate 179 mounted on the rotating plate 8, an elastic rod 1710 mounted on the rounded corner plate 179, an inclined block 1711 mounted on the filter cylinder 6, and a rounded corner block 1712 mounted on the elastic rod 1710. The rounded corner block 1712 will contact the inclined block 1711 during rotation. A spring is provided between the rounded corner block 1712 and the rounded corner plate 179. The rounded corner block 1712 is used to generate vibration of the filter cylinder 6. The movement of the rounded corner block 1712 will compress the spring on the surface of the elastic rod 1710.

[0035] The inclined block 1711 and the rounded corner block 1712 are in contact with each other, the moving rod 175 is fixedly connected to the L-shaped sealing plate 176, the triangular block 178 and the trapezoidal block 177 are in contact with each other, and the rounded plate 173 is in contact with the outer rotating plate 11.

[0036] During backwashing, the rotation of the rotating plate 8 drives the rounded corner plate 179 to rotate, which in turn drives the elastic rod 1710 to rotate. The rotation of the elastic rod 1710 drives the rounded corner block 1712 to rotate. During rotation, the rounded corner block 1712 comes into contact with the inclined block 1711 and is pushed to move by the squeezing force. At the same time, it drives the elastic rod 1710 to move. The movement of the rounded corner block 1712 compresses the spring on the surface of the elastic rod 1710. When the rounded corner block 1712 passes the inclined block 1711, the elastic rod 1710 will be reset by the spring and will generate an impact force on the filter cylinder 6. This can actively shake off the mud, suspended debris, oil and flocculated flocs adhering to the surface of the filter cylinder 6, avoid long-term adhesion and accumulation of impurities, reduce the dirt load on the surface of the filter cylinder 6, assist backwashing, and improve the self-cleaning effect.
