Description

Technical Field

[0001] The present invention relates to the technical field of horizontal filters, and specifically to a horizontal filter capable of hierarchical treatment. Background Art

[0002] In industrial production and daily life, water filtration equipment plays a crucial role. With the enhancement of environmental awareness, the refined development of production processes, and the increasing demand for high-quality water, the performance requirements for filtration equipment are becoming increasingly stringent. In the current market, most common filters adopt a single filtration structure. For example, a simple screen filter can only remove large-particle impurities in water; or an activated carbon filter can adsorb some organic pollutants and odors, but it is difficult to handle various impurities with a wide range of particle sizes. These single filtration methods have obvious limitations and cannot meet the hierarchical filtration requirements for different particle-size impurities at the same time. When dealing with complex water quality, the filtration effect is not good, and the quality of the discharged water is difficult to meet high-standard requirements. In addition, after long-term use of a single filtration device, impurities are likely to accumulate in the filter, resulting in a decrease in filtration efficiency and serious blockage. Frequent replacement of the filtration medium will not only increase the equipment maintenance cost, but also may affect the normal operation and energy efficiency of the equipment. Summary of the Invention

[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: A horizontal filter capable of hierarchical treatment, comprising: a filter tank, on the bottom of which a support frame and a discharge pipe are respectively fixedly installed. The support frame is fixedly installed on both sides of the bottom of the filter tank, and the discharge pipe is fixedly installed in the middle of the bottom of the filter tank. On both sides of the outer surface of the filter tank, a cleaning conduit and a discharge conduit are respectively fixedly installed; A shunt assembly for guiding and collecting sewage. A guiding connection pipe is fixedly installed on the outer surface of the shunt assembly. There are three guiding connection pipes, and all three guiding connection pipes are fixedly installed on the top of the filter tank; An internal filter chamber group for primary filtration of sewage, which is arranged inside the filter tank; A guiding assembly for discharging the filtered liquid. The guiding assembly is communicated with the discharge conduit, the cleaning conduit, and the internal filter chamber group, and the guiding assembly is installed inside the filter tank. When the staff connects the horizontal filter to the pipeline, before the sewage in the pipeline enters the interior of the filter tank along the shunt assembly in the guiding connection pipe, the larger impurities are dispersed by the shunt assembly and enter the filter tank together with the sewage. The sewage in the filter tank is filtered by the internal filter chamber group and undergoes primary screening with the impurities. The water filtered in the internal filter chamber group is transported out of the filter tank along the guiding assembly. At this time, the filtering guide cylinder installed in the guiding assembly filters the filtered water again to achieve multi-stage filtration of the sewage.

[0004] Preferably, the internal filter chamber group includes an inner cylinder. A guide groove is fixedly installed inside the inner cylinder. A filter element is fixedly installed on the outer surface of the inner cylinder. An installation cover is fixedly installed on the surface of the inner cylinder close to the outlet pipe. A filter cover is fixedly installed inside the installation cover. After the sewage enters the filter tank, it enters the inside of the inner cylinder after being filtered by the filter cover and the filter element. Dense filter holes are provided on the surface of the filter cover to filter the impurities in the sewage.

[0005] Preferably, the inner cylinder is fixedly installed on the outer surface of the diversion component. There are six groups of the filter elements. The six groups of filter elements are circumferentially distributed on the surface of the inner cylinder. The filter element is adapted to the guide groove.

[0006] Preferably, the filter element includes an inner connection pad. There are two inner connection pads. A filter sheet is fixedly installed between the opposite surfaces of the two inner connection pads. A cover cylinder is sleeved on the outer surface of the filter sheet. Drainage grooves are formed on both sides of the outer surface of the cover cylinder.

[0007] Preferably, the inner connection pad is fixedly installed inside the guide groove. The cover cylinder is fixedly installed between the adjacent surfaces of the guide groove through the inner connection pad. The drainage groove is communicated with the guide groove. The sewage in the filter tank enters the cover cylinder along the drainage groove formed on the surface of the cover cylinder. The sewage contacts the filter sheet. The filter sheet adsorbs the impurities in the sewage. Then the sewage enters the guide groove along the drainage groove on the other side of the cover cylinder. The impurities in the sewage are adsorbed and filtered by multiple groups of filter sheets to improve the filtration efficiency.

[0008] Preferably, the diversion component includes a connection seat. An extension pipe is fixedly installed in the middle of the outer surface of the connection seat. A gasket ring is fixedly installed on the outer surface of the extension pipe. A positioning pipe is fixedly installed at the edge of the outer surface of the connection seat. There are four positioning pipes. One end of a diversion elbow is fixedly installed inside each of the four positioning pipes. The other end of the diversion elbow is fixedly installed with a filter guide cylinder. A liquid outlet pipe is fixedly installed at the axis of the outer surface of the filter guide cylinder. The water filtered in the inner cylinder enters the diversion elbow along the connection seat. A filter plate is installed at the connection of the diversion elbow and the positioning pipe. The filter plate intercepts and filters the impurities in the water flow. Then it is conveyed into the filter guide cylinder along multiple groups of diversion elbows. An activated carbon adsorption material is placed in the filter guide cylinder to filter the filtered water again.

[0009] Preferably, the connection seat is fixedly installed on the side of the inner cylinder away from the filter cover. The gasket ring is fixedly connected to the cleaning conduit, the liquid outlet pipe is fixedly connected to the outlet pipe, and both the extension pipe and the positioning pipe communicate with the inner cylinder. After the sewage filtration is completed, the staff injects clean water into the extension pipe through the cleaning conduit to wash the impurities intercepted and filtered in the inner filter cavity group. At this time, the sewage generated by the cleaning and the impurities in the filter tank are discharged along the discharge pipe at the bottom of the filter tank, which facilitates the subsequent cleaning of the filter and prevents impurities from easily accumulating in the filter, resulting in a decrease in filtration efficiency and serious blockage. Frequent replacement of the filter medium will not only increase the equipment maintenance cost but also may affect the normal operation and energy efficiency of the equipment.

[0010] Preferably, the shunt assembly includes a shunt member. The shunt member is fixedly installed inside the guiding connection pipe. A micro motor is fixedly installed at the axis inside the shunt member. The output end of the micro motor is fixedly installed with a rotating shaft. Blades are rotatably installed on the outer surface of the rotating shaft. A fitting piece is fixedly installed on the outer surface of the shunt member. A guiding vane is fixedly installed at the bottom of the fitting piece. There are four fitting pieces, and the four fitting pieces are distributed in a circular shape at the bottom of the shunt member. The staff connects the guiding connection pipe to the pipeline so that the sewage is discharged into the guiding connection pipe. The shunt member installed inside the guiding connection pipe shunts the sewage. The micro motor installed at the bottom of the shunt member drives the rotating shaft and the blades to rotate. At this time, the blades contact the sewage discharged from the shunt member and crush the larger impurities in the sewage to reduce the volume of the impurities, facilitating the cleaning of the filtered impurities. When the sewage is stirred by the blades, the rotation of the blades affects the flow direction of the water flow, causing the sewage to flow downward along the guiding vane into the filter tank.

[0011] Preferably, the shunt member includes a clamping seat. A positioning ring is fixedly installed inside the clamping seat. A circular ring cover is fixedly installed inside the positioning ring. Flow guiding holes are opened at the edge of the outer surface of the circular ring cover. A reinforcing seat is fixedly installed at the bottom of the clamping seat. An extension ring is fixedly installed at the bottom of the reinforcing seat.

[0012] Preferably, both the clamping seat and the reinforcing seat are fixedly installed on the inner wall of the guiding connection pipe. The circular ring cover is fixedly installed on the top of the micro motor. The extension ring is fixedly connected to the fitting piece. The clamping seat and the reinforcing seat are installed inside the guiding connection pipe. When the sewage is transported along the guiding connection pipe to above the circular ring cover, since the circular ring cover is arranged in an arc-shaped convex structure, it is convenient for the sewage to flow to the side of the circular ring cover and discharge along the flow guiding holes. The circular ring cover and the flow guiding holes limit the flow velocity of the sewage. The sewage is shunted by reducing the flow velocity of the sewage. The sewage enters the filter tank from the flow guiding holes. Using the principle of slow flow and sedimentation, large particle impurities will settle to the bottom of the filter tank.

[0013] The present invention provides a horizontal filter capable of hierarchical treatment, having the following beneficial effects: 1. For this horizontally - filter that can be hierarchically processed, the sewage in the filter tank enters the shroud through the drainage grooves opened on the surface of the shroud. The sewage contacts the filter discs, and the filter discs adsorb the impurities in the sewage. Then the sewage enters the guide groove through the drainage grooves on the other side of the shroud, and multiple groups of filter discs adsorb and filter the sewage impurities to improve the filtration efficiency.

[0014] 2. For this horizontally - filter that can be hierarchically processed, the water filtered in the inner cylinder enters the diversion elbow through the connecting seat. A filter plate is installed at the connection between the diversion elbow and the positioning pipe to intercept and filter the impurities in the water flow. Then it is conveyed into the filter guide cylinder along multiple diversion elbows. Activated carbon adsorption materials are placed in the filter guide cylinder to re - filter the filtered water.

[0015] 3. For this horizontally - filter that can be hierarchically processed, after the sewage filtration is completed, the staff injects clean water into the extension pipe through the cleaning conduit to wash the impurities intercepted and filtered in the inner filter cavity group. At this time, the sewage generated by the cleaning and the impurities in the filter tank are discharged through the discharge pipe at the bottom of the filter tank, which is convenient for the subsequent cleaning of the filter, avoiding the easy accumulation of impurities in the filter, resulting in a decrease in filtration efficiency and serious blockage. Frequent replacement of the filter medium will not only increase the equipment maintenance cost but also may affect the normal operation and energy efficiency of the equipment.

[0016] 4. For this horizontally - filter that can be hierarchically processed, the staff connects the guide connection pipe to the pipeline so that the sewage is discharged into the guide connection pipe. The flow - dividing part installed in the guide connection pipe divides the sewage. The micro - motor installed at the bottom of the flow - dividing part drives the rotation of the rotating shaft and the blades. At this time, the blades contact the sewage discharged from the flow - dividing part and crush the larger impurities in the sewage to reduce the volume of the impurities, which is convenient for the cleaning of the filtered impurities. When the sewage is agitated by the blades, the rotation of the blades affects the flow direction of the water flow, causing the sewage to flow downward along the guide vanes into the filter tank.

[0017] 5. For this horizontally - filter that can be hierarchically processed, the clamping seat and the reinforcement seat are installed inside the guide connection pipe. When the sewage is conveyed to above the circular shroud along the guide connection pipe, since the circular shroud is set as an arc - shaped convex structure, it is convenient for the sewage to flow to the side of the circular shroud and be discharged along the diversion holes. The circular shroud and the diversion holes limit the flow rate of the sewage, and the sewage is divided by reducing the sewage flow rate. The sewage enters the filter tank from the diversion holes, and using the principle of slow - flow sedimentation, the large - particle impurities will precipitate to the bottom of the filter tank.

The staff connects the horizontal filter to the pipeline. Before the sewage in the pipeline enters the filter tank 1 along the diverter component 6 in the guide pipe 3, the larger impurities are broken up by the diverter component 6 and enter the filter tank 1 at the same time as the sewage. The sewage in the filter tank 1 is filtered through the inner filter chamber group 8 to perform primary screening with the impurities. The filtered water in the inner filter chamber group 8 is transported to the outside of the filter tank 1 along the flow guide component 4. At this time, the filter guide cylinder 47 installed in the flow guide component 4 filters the filtered water again to achieve multi-stage filtration of the sewage.

[0022] The diversion assembly 4 includes a connection seat 45, an extension tube 43 is fixedly installed in the middle of the outer surface of the connection seat 45, a gasket 42 is fixedly installed on the outer surface of the extension tube 43, a positioning tube 44 is fixedly installed at the edge of the outer surface of the connection seat 45, and four positioning tubes 44 are provided.

Frequent replacement of the filter medium will not only increase the equipment maintenance cost, but also may affect the normal operation and energy efficiency of the equipment.

[0024] Second embodiment, on the basis of the first embodiment, please refer to Figures 6 to 8 As shown in the figure, the inner filter cavity group 8 includes an inner layer cylinder 81. A guide groove 85 is fixedly installed inside the inner layer cylinder 81. A filter element 82 is fixedly installed on the outer surface of the inner layer cylinder 81. An installation cover 84 is fixedly installed on the surface of the inner layer cylinder 81 close to the outlet pipe 5. A filter cover 83 is fixedly installed inside the installation cover 84. After the sewage enters the filter tank 1, it enters the inside of the inner layer cylinder 81 after being filtered by the filter cover 83 and the filter element 82. Dense filter holes are provided on the surface of the filter cover 83 to filter the impurities in the sewage.

[0025] The inner layer cylinder 81 is fixedly installed on the outer surface of the diversion assembly 4. Six groups of the filter elements 82 are provided. The six groups of the filter elements 82 are circumferentially distributed on the surface of the inner layer cylinder 81. The filter element 82 is adapted to the guide groove 85.

[0026] The filter element 82 includes an inner connecting pad 821. Two inner connecting pads 821 are provided. A filter sheet 824 is fixedly installed between the opposite surfaces of the two inner connecting pads 821. A cover cylinder 822 is sleeved on the outer surface of the filter sheet 824. Drainage grooves 823 are opened on both sides of the outer surface of the cover cylinder 822.

[0027] The inner connecting pad 821 is fixedly installed inside the guide groove 85. The cover cylinder 822 is fixedly installed between the adjacent surfaces of the guide groove 85 through the inner connecting pad 821. The drainage groove 823 is communicated with the guide groove 85. The sewage in the filter tank 1 enters the cover cylinder 822 along the drainage groove 823 opened on the surface of the cover cylinder 822. The sewage contacts the filter sheet 824. The filter sheet 824 adsorbs the impurities in the sewage. Then the sewage enters the guide groove 85 along the drainage groove 823 on the other side of the cover cylinder 822. The sewage impurities are adsorbed and filtered by multiple groups of filter sheets 824 to improve the filtration efficiency.

[0028] Third embodiment, on the basis of the first and second embodiments, please refer to Figures 1 to 11As shown, the shunt assembly 6 includes a shunt member 62, which is fixedly installed inside the guiding pipe 3. At the axis inside the shunt member 62, a micro-motor 65 is fixedly installed. The output end of the micro-motor 65 is fixedly installed with a rotating shaft 64. A blade 66 is rotatably installed on the outer surface of the rotating shaft 64. A fitting piece 61 is fixedly installed on the outer surface of the shunt member 62. At the bottom of the fitting piece 61, a guiding vane 63 is fixedly installed. There are four fitting pieces 61, and the four fitting pieces 61 are circumferentially distributed at the bottom of the shunt member 62. The staff connects the guiding pipe 3 with the pipeline so that sewage is discharged into the guiding pipe 3. The shunt member 62 installed in the guiding pipe 3 shunts the sewage. The micro-motor 65 installed at the bottom of the shunt member 62 drives the rotating shaft 64 and the blade 66 to rotate. At this time, the blade 66 contacts the sewage discharged from the shunt member 62 and crushes the larger impurities in the sewage to reduce the volume of the impurities, facilitating the cleaning of the impurities to be filtered out. When the sewage is stirred by the blade 66, the rotation of the blade 66 affects the flow direction of the water flow, causing the sewage to flow downward along the guiding vane 63 into the filtering tank 1.

[0029] The shunt member 62 includes a clamping seat 621. Inside the clamping seat 621, a positioning ring 626 is fixedly installed. Inside the positioning ring 626, a circular ring cover 622 is fixedly installed. At the outer surface edge of the circular ring cover 622, a guiding hole 623 is opened. At the bottom of the clamping seat 621, a reinforcing seat 625 is fixedly installed. At the bottom of the reinforcing seat 625, an extension ring 624 is fixedly installed.

[0030] Both the clamping seat 621 and the reinforcing seat 625 are fixedly installed on the inner wall of the guiding pipe 3. The circular ring cover 622 is fixedly installed on the top of the micro-motor 65. The extension ring 624 is fixedly connected with the fitting piece 61. When the clamping seat 621 and the reinforcing seat 625 are installed inside the guiding pipe 3 and the sewage is transported along the guiding pipe 3 to above the circular ring cover 622, since the circular ring cover 622 is arranged in an arc-shaped convex structure, it is convenient for the sewage to flow to the side of the circular ring cover 622 and be discharged along the guiding hole 623. The circular ring cover 622 and the guiding hole 623 limit the flow rate of the sewage, and the sewage is shunted by reducing the sewage flow rate. The sewage enters the filtering tank 1 from the guiding hole 623. Using the slow-flow sedimentation principle, the large-particle impurities will precipitate to the bottom of the filtering tank 1.

[0031] During use, the staff connects the horizontal filter with the pipeline. Before the sewage in the pipeline enters the inside of the filtering tank 1 along the shunt assembly 6 in the guiding pipe 3, the larger impurities are scattered by the shunt assembly 6 and enter the filtering tank 1 together with the sewage. The sewage in the filtering tank 1 is initially screened for filtration and impurities through the inner filter cavity group 8. The water filtered in the inner filter cavity group 8 is transported out of the filtering tank 1 along the guiding assembly 4. At this time, the filtering guide cylinder 47 installed in the guiding assembly 4 filters the filtered water again to achieve multi-stage filtration of the sewage.

[0032] The staff connects the guiding connecting pipe 3 with the pipeline to discharge sewage into the guiding connecting pipe 3. The flow dividing member 62 installed in the guiding connecting pipe 3 divides the sewage. The micro motor 65 installed at the bottom of the flow dividing member 62 drives the rotating shaft 64 and the blade 66 to rotate. At this time, the blade 66 contacts the sewage discharged from the flow dividing member 62 and crushes the larger impurities in the sewage to reduce the volume of the impurities, facilitating the cleaning of the filtered impurities. When the sewage is stirred by the blade 66, the rotation of the blade 66 affects the flow direction of the water flow, causing the sewage to flow downward along the guiding vane 63 into the filtering tank 1.

[0033] The clamping seat 621 and the reinforcing seat 625 are installed inside the guiding connecting pipe 3. When the sewage is conveyed along the guiding connecting pipe 3 to above the circular ring cover 622, since the circular ring cover 622 is set as an arc-shaped convex structure, it is convenient for the sewage to flow to the side of the circular ring cover 622 and discharge along the guiding holes 623. The circular ring cover 622 and the guiding holes 623 limit the flow velocity of the sewage, and the sewage is divided by reducing the sewage flow velocity. The sewage enters the filtering tank 1 from the guiding holes 623. Using the slow flow sedimentation principle, the large particle impurities will precipitate to the bottom of the filtering tank 1.

[0034] After the sewage enters the filtering tank 1, it enters the inside of the inner layer cylinder 81 after being filtered by the filtering cover 83 and the filtering member 82. The surface of the filtering cover 83 is provided with dense filtering holes to filter the impurities in the sewage.

[0035] The sewage in the filtering tank 1 enters the cover cylinder 822 along the drainage groove 823 opened on the surface of the cover cylinder 822. The sewage contacts the filter plate 824, and the filter plate 824 adsorbs the impurities in the sewage. Then the sewage enters the guide groove 85 along the drainage groove 823 on the other side of the cover cylinder 822, and the sewage impurities are adsorbed and filtered by multiple groups of filter plates 824 to improve the filtering efficiency.

[0036] The filtered water in the inner layer cylinder 81 enters the guiding elbow 41 along the connecting seat 45. A filter plate is installed at the connection of the guiding elbow 41 and the positioning pipe 44 to intercept and filter the impurities in the water flow. Then it is conveyed to the filtering guide cylinder 47 along multiple groups of guiding elbows 41. An activated carbon adsorption material is placed in the filtering guide cylinder 47 to filter the filtered water again.

[0037] After the sewage filtration is completed, the staff injects clean water into the extension pipe 43 through the cleaning conduit 7 to wash the impurities intercepted and filtered in the inner filter cavity group 8. At this time, the sewage generated by the cleaning and the impurities in the filtering tank 1 are discharged along the discharge pipe 9 at the bottom of the filtering tank 1, facilitating the subsequent cleaning of the filter, avoiding the easy accumulation of impurities in the filter, resulting in a decrease in the filtering efficiency and serious blockage. Frequent replacement of the filtering medium will not only increase the equipment maintenance cost, but also may affect the normal operation and energy efficiency of the equipment.
