Description

Technical Field

[0001] The invention relates to the technical field of horizontal filters, in particular to a horizontal filter capable of graded treatment. Background Art

[0002] Water filtration equipment plays a vital role in industrial production and daily life. With the increasing awareness of environmental protection, the refinement of production processes, and the increasing demand for high-quality water, the performance requirements for filtration equipment are becoming increasingly stringent.

[0003] Currently, most common filters on the market use a single filtration structure. For example, simple mesh filters can only remove larger particles of impurities in the water; or activated carbon filters, although they can absorb some organic pollutants and odors, have difficulty dealing with a wide range of impurities with a wide range of particle sizes. These single filtration methods have obvious limitations and cannot simultaneously meet the needs of graded filtration of impurities of different particle sizes. When dealing with complex water quality, the filtration effect is poor, and the effluent water quality is difficult to meet high standards. In addition, after long-term use of single filtration equipment, impurities easily accumulate in the filter, resulting in reduced filtration efficiency and severe clogging. Frequent replacement of filter media not only leads to increased equipment maintenance costs, but may also affect the normal operation and energy efficiency of the equipment. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a horizontal filter capable of graded treatment, comprising: a filter tank, a support frame and a discharge pipe are fixedly installed at the bottom of the filter tank, the support frame is fixedly installed on both sides of the bottom of the filter tank, the discharge pipe is fixedly installed in the middle of the bottom of the filter tank, and a cleaning conduit and a discharge pipe are fixedly installed on both sides of the outer surface of the filter tank;

[0005] A diversion assembly is used to divert and collect sewage. A guide tube is fixedly installed on the outer surface of the diversion assembly. Three guide tubes are provided and all three guide tubes are fixedly installed on the top of the filter tank;

[0006] An inner filter chamber group, which is used for primary filtration of sewage and is arranged inside the filter tank;

[0007] The diversion assembly is used to guide the filtered liquid out. The diversion assembly is connected to the outlet pipe, the cleaning conduit, and the inner filter chamber group. The diversion assembly is installed inside the filter tank. The staff connects the horizontal filter to the pipeline. Before the sewage in the pipeline enters the filter tank along the diversion assembly in the diversion pipe, larger impurities are broken up by the diversion assembly and enter the filter tank at the same time as the sewage. The sewage in the filter tank is filtered through the inner filter chamber group to undergo primary screening of impurities. The filtered water in the inner filter chamber group is transported out of the filter tank along the diversion assembly. At this time, the filter guide cylinder installed in the diversion assembly filters the filtered water again to achieve multi-stage filtration of the sewage.

[0008] Preferably, the inner filter chamber assembly includes an inner tube having a guide groove fixedly mounted therein, a filter element fixedly mounted on the outer surface of the inner tube, a mounting cover fixedly mounted on the surface of the inner tube near the outlet pipe, and a filter cover fixedly mounted within the mounting cover. After sewage enters the filter tank, it is filtered by the filter cover and the filter element before entering the interior of the inner tube. The filter cover is provided with dense filter holes on its surface to filter impurities in the sewage.

[0009] Preferably, the inner cylinder is fixedly mounted on the outer surface of the guide assembly, and six groups of filter elements are provided. The six groups of filter elements are distributed in a circular shape on the surface of the inner cylinder, and the filter elements are adapted to the guide grooves.

[0010] Preferably, the filter element includes an internal pad, two of which are provided, a filter disc is fixedly installed between opposite surfaces of the two internal pads, a cover tube is provided on the outer surface of the filter disc, and drainage grooves are provided on both sides of the outer surface of the cover tube.

[0011] Preferably, the internal gasket is fixedly mounted within the guide groove, the cover tube is fixedly mounted between adjacent surfaces of the guide groove via the internal gasket, and the drainage groove is connected to the guide groove. Sewage in the filter tank flows into the cover tube along the drainage groove provided on the surface of the cover tube, where it contacts the filter discs, which adsorb impurities in the sewage. The sewage then flows into the guide groove along the other side of the cover tube, where it is adsorbed and filtered by multiple groups of filter discs, thereby improving filtration efficiency.

[0012] Preferably, the diversion assembly includes a connecting seat, an extension tube fixedly mounted in the middle of the outer surface of the connecting seat, a gasket fixedly mounted on the outer surface of the extension tube, a positioning tube fixedly mounted on the edge of the outer surface of the connecting seat, four positioning tubes provided, one end of a diversion elbow fixedly mounted inside each of the four positioning tubes, a filter guide fixedly mounted on the other end of the diversion elbow, and a liquid outlet pipe fixedly mounted at the axis of the outer surface of the filter guide. Water filtered in the inner tube flows through the connecting seat into the diversion elbow, a filter plate is mounted at the connection between the diversion elbow and the positioning tube, the filter plate intercepts and filters impurities in the water flow, and then transports the impurities along multiple groups of diversion elbows to the filter guide, which contains activated carbon adsorption material for further filtering and treating the filtered water.

[0013] Preferably, the connecting seat is fixedly mounted on the side of the inner tube away from the filter housing, the gasket is fixedly connected to the cleaning conduit, the liquid outlet pipe is fixedly connected to the outlet pipe, and the extension pipe and the positioning pipe are both in communication with the inner tube. After the sewage is filtered, the staff injects clean water into the extension pipe through the cleaning conduit to flush 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 to facilitate the subsequent cleaning of the filter, thereby preventing impurities from easily accumulating in the filter, resulting in reduced filtration efficiency and serious clogging. Frequent replacement of the filter medium will not only increase the maintenance cost of the equipment, but may also affect the normal operation and energy efficiency of the equipment.

[0014] Preferably, the diversion assembly includes a diversion member, which is fixedly mounted inside the guide tube, a micro motor is fixedly mounted at the axis of the diversion member, a rotating shaft is fixedly mounted on the output end of the micro motor, a blade is rotatably mounted on the outer surface of the rotating shaft, a fitting sheet is fixedly mounted on the outer surface of the diversion member, a guide sheet is fixedly mounted on the bottom of the fitting sheet, four fitting sheets are provided, and the four fitting sheets are distributed in a circular shape at the bottom of the diversion member. The staff connects the guide tube to the pipeline to discharge the sewage into the guide tube, the diversion member installed in the guide tube diverts the sewage, and the micro motor installed at the bottom of the diversion member drives the rotating shaft and blades to rotate. At this time, the blades come into contact with the sewage discharged from the diversion member and crush larger impurities in the sewage to reduce the volume of the impurities and facilitate 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, causing the sewage to flow down along the guide sheet into the filter tank.

[0015] Preferably, the diverter includes a snap-fit ​​seat, a positioning ring is fixedly installed inside the snap-fit ​​seat, a circular cover is fixedly installed inside the positioning ring, a guide hole is opened at the edge of the outer surface of the circular cover, a reinforcement seat is fixedly installed at the bottom of the snap-fit ​​seat, and an extension ring is fixedly installed at the bottom of the reinforcement seat.

[0016] Preferably, the adapter and the reinforcement seat are both fixedly mounted on the inner wall of the guide tube, the annular cover is fixedly mounted on the top of the micromotor, and the extension ring is fixedly connected to the bonding sheet. The adapter and the reinforcement seat are mounted inside the guide tube. When sewage is transported along the guide tube to the top of the annular cover, the annular cover is configured as an arc-shaped raised structure, allowing the sewage to flow toward the side of the annular cover and be discharged through the diversion hole. The annular cover and the diversion hole limit the flow rate of the sewage, thereby diverting the sewage by reducing the flow rate. The sewage enters the filter tank through the diversion hole, and large particles of impurities are deposited at the bottom of the filter tank by utilizing the slow flow sedimentation principle.

[0017] The present invention provides a horizontal filter capable of graded treatment, which has the following beneficial effects:

[0018] 1. This horizontal filter with graded treatment allows the sewage in the filter tank to enter the cover barrel along the drainage groove opened on the surface of the cover barrel. The sewage contacts the filter disc, which adsorbs impurities in the sewage. Then the sewage enters the guide groove along the drainage groove on the other side of the cover barrel. The sewage impurities are adsorbed and filtered through multiple groups of filter discs to improve the filtration efficiency.

[0019] 2. The horizontal filter with graded treatment, the water after being filtered in the inner tube enters the diversion elbow along the connecting seat. A filter plate is installed at the connection between the diversion elbow and the positioning tube. The filter plate intercepts and filters the impurities in the water flow, and then transports it along multiple groups of diversion elbows to the filter guide tube. Activated carbon adsorption material is placed in the filter guide tube to filter and treat the filtered water again.

[0020] 3. After the horizontal filter with graded treatment completes the sewage filtration, the staff injects clean water into the extension pipe through the cleaning catheter to flush the impurities intercepted and filtered in the inner filter chamber group. At this time, the sewage generated by cleaning and the impurities in the filter tank are discharged along the discharge pipe at the bottom of the filter tank to facilitate subsequent cleaning of the filter, avoiding the accumulation of impurities in the filter, resulting in reduced filtration efficiency and serious blockage. Frequent replacement of filter media will not only increase the equipment maintenance cost, but may also affect the normal operation and energy efficiency of the equipment.

[0021] 4. The horizontal filter with graded treatment is connected to the pipe by the staff to discharge the sewage into the pipe. The diverter installed in the pipe diverts the sewage. The micro motor installed at the bottom of the diverter drives the shaft and blades to rotate. At this time, the blades come into contact with the sewage discharged from the diverter and crush the larger impurities in the sewage to reduce the volume of the impurities and facilitate 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, causing the sewage to flow downward along the guide plate into the filter tank.

[0022] 5. The horizontal filter with graded treatment is installed inside the guide tube through a clamping seat and a reinforcement seat. When the sewage is transported along the guide tube to the top of the annular cover, the annular cover is provided with an arc-shaped convex structure, so that the sewage flows to the side of the annular cover and is discharged along the diversion hole. The annular cover and the diversion hole limit the flow speed of the sewage, and the sewage is diverted by reducing the flow rate of the sewage. The sewage enters the filter tank from the diversion hole, and the large particles of impurities will settle to the bottom of the filter tank by using the slow flow sedimentation principle.

[0036] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: a horizontal filter capable of graded treatment, comprising: a filter tank 1, a support frame 2 and a discharge pipe 9 are fixedly mounted on the bottom of the filter tank 1, the support frame 2 is fixedly mounted on both sides of the bottom of the filter tank 1, the discharge pipe 9 is fixedly mounted in the middle of the bottom of the filter tank 1, and a cleaning guide 7 and a discharge pipe 5 are fixedly mounted on both sides of the outer surface of the filter tank 1;

[0037] A diverter assembly 6 is used to divert and collect sewage. A guide tube 3 is fixedly mounted on the outer surface of the diverter assembly 6. Three guide tubes 3 are provided. All three guide tubes 3 are fixedly mounted on the top of the filter tank 1.

[0038] An inner filter chamber group 8, which is used for primary filtration of sewage and is disposed inside the filter tank 1;

[0039] The diversion assembly 4 is used to guide the filtered liquid out. It is connected to the outlet pipe 5, the cleaning conduit 7, and the inner filter chamber group 8. The diversion assembly 4 is installed inside the filter tank 1. When the staff connects the horizontal filter to the pipeline, the sewage in the pipeline flows along the diversion assembly 6 in the diversion pipe 3 before entering the filter tank 1. Larger impurities are broken up by the diversion assembly 6 and enter the filter tank 1 simultaneously with the sewage. The sewage in the filter tank 1 is filtered through the inner filter chamber group 8 for primary screening of impurities. The filtered water in the inner filter chamber group 8 is then transported out of the filter tank 1 along the diversion assembly 4. At this time, the filter guide cylinder 47 installed in the diversion assembly 4 filters the filtered water again, achieving multi-stage filtration of the sewage.

[0040] The diversion assembly 4 includes a connection seat 45, with an extension tube 43 fixedly mounted in the middle of the outer surface of the connection seat 45. A gasket 42 is fixedly mounted on the outer surface of the extension tube 43. A positioning tube 44 is fixedly mounted on the edge of the outer surface of the connection seat 45. Four positioning tubes 44 are provided, each of which has one end of a diversion elbow 41 fixedly mounted inside. A filter guide 47 is fixedly mounted on the other end of the diversion elbow 41. A liquid outlet pipe 46 is fixedly mounted at the axis of the outer surface of the filter guide 47. The filtered water in the inner tube 81 flows through the connection seat 45 into the diversion elbow 41. A filter plate is installed at the connection between the diversion elbow 41 and the positioning tube 44. The filter plate intercepts and filters impurities in the water flow, and then transports the impurities along the multiple diversion elbows 41 to the filter guide 47. The filter guide 47 contains activated carbon adsorption material to further filter and treat the filtered water.

[0041] The connecting seat 45 is fixedly mounted on the side of the inner tube 81 away from the filter cover 83, the gasket 42 is fixedly connected to the cleaning conduit 7, the liquid outlet pipe 46 is fixedly connected to the outlet pipe 5, and the extension pipe 43 and the positioning pipe 44 are both in communication with the inner tube 81. After the sewage filtration is completed, the staff injects clean water into the extension pipe 43 through the cleaning conduit 7 to flush 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 filter tank 1 are discharged through the discharge pipe 9 at the bottom of the filter tank 1 to facilitate the subsequent cleaning of the filter and prevent impurities from accumulating easily in the filter, resulting in a decrease in filtration efficiency and serious clogging. Frequent replacement of the filter medium will not only increase the maintenance cost of the equipment, but may also affect the normal operation and energy efficiency of the equipment.

[0042] The second embodiment, based on the first embodiment, see Figures 6 to 8As shown, the inner filter chamber group 8 includes an inner tube 81, a guide groove 85 fixedly installed inside the inner tube 81, a filter element 82 fixedly installed on the outer surface of the inner tube 81, and a mounting cover 84 fixedly installed on the surface of the inner tube 81 near the outlet pipe 5. A filter cover 83 is fixedly installed inside the mounting cover 84. After the sewage enters the filter tank 1, it is filtered by the filter cover 83 and the filter element 82 before entering the interior of the inner tube 81. The surface of the filter cover 83 is provided with dense filter holes to filter impurities in the sewage.

[0043] The inner tube 81 is fixedly mounted on the outer surface of the guide assembly 4 . Six groups of filter elements 82 are provided. The six groups of filter elements 82 are distributed in a circular shape on the surface of the inner tube 81 . The filter elements 82 are adapted to the guide grooves 85 .

[0044] The filter element 82 includes an internal pad 821, two of which are provided. A filter disc 824 is fixedly installed between the opposite surfaces of the two internal pads 821. The outer surface of the filter disc 824 is sleeved with a cover tube 822, and drainage grooves 823 are opened on both sides of the outer surface of the cover tube 822.

[0045] The internal gasket 821 is fixedly mounted inside the guide groove 85. The cover tube 822 is fixedly mounted between adjacent surfaces of the guide groove 85 via the internal gasket 821. The drainage groove 823 is connected to the guide groove 85. The sewage in the filter tank 1 flows into the cover tube 822 along the drainage groove 823 provided on the surface of the cover tube 822. The sewage contacts the filter disc 824, which absorbs impurities in the sewage. The sewage then flows into the guide groove 85 along the drainage groove 823 on the other side of the cover tube 822. The sewage is then absorbed and filtered by multiple groups of filter discs 824, thereby improving filtration efficiency.

[0046] The third embodiment, based on the first and second embodiments, see Figures 1 to 11As shown, the diverter assembly 6 includes a diverter 62, which is fixedly mounted inside the guide tube 3, and a micro motor 65 is fixedly mounted at the axis inside the diverter 62, and a rotating shaft 64 is fixedly mounted on the output end of the micro motor 65, and a blade 66 is rotatably mounted on the outer surface of the rotating shaft 64, and a fitting sheet 61 is fixedly mounted on the outer surface of the diverter 62, and a guide sheet 63 is fixedly mounted on the bottom of the fitting sheet 61, and four fitting sheets 61 are provided, and the four fitting sheets 61 are distributed in a circular shape at the bottom of the diverter 62. The staff connects the guide tube 3 to the pipeline to discharge the sewage into the guide tube 3. The diverter 62 installed in the guide tube 3 diverts the sewage. The micro motor 65 installed at the bottom of the diverter 62 drives the rotating shaft 64 and the blades 66 to rotate. At this time, the blades 66 come into contact with the sewage discharged from the diverter 62 and crush the larger impurities in the sewage to reduce the volume of the impurities and facilitate the cleaning of the filtered impurities; when the sewage is stirred by the blades 66, the rotation of the blades 66 affects the flow direction of the water, so that the sewage flows downward along the guide plate 63 into the filter tank 1.

[0047] The diverter 62 includes a clamping seat 621, a positioning ring 626 is fixedly installed inside the clamping seat 621, a circular ring cover 622 is fixedly installed inside the positioning ring 626, a guide hole 623 is opened at the edge of the outer surface of the circular ring cover 622, a reinforcement seat 625 is fixedly installed at the bottom of the clamping seat 621, and an extension ring 624 is fixedly installed at the bottom of the reinforcement seat 625.

[0048] The clamping seat 621 and the reinforcement seat 625 are both fixedly mounted on the inner wall of the guide tube 3, the annular cover 622 is fixedly mounted on the top of the micro-motor 65, and the extension ring 624 is fixedly connected to the bonding sheet 61. The clamping seat 621 and the reinforcement seat 625 are mounted inside the guide tube 3. When sewage is transported along the guide tube 3 to the top of the annular cover 622, the annular cover 622 is configured as an arc-shaped raised structure, allowing the sewage to flow toward the side of the annular cover 622 and be discharged through the diversion hole 623. The annular cover 622 and the diversion hole 623 limit the flow speed of the sewage, thereby diverting the sewage by reducing the sewage flow rate. The sewage enters the filter tank 1 through the diversion hole 623, and large particles of impurities are deposited at the bottom of the filter tank 1 by utilizing the slow flow sedimentation principle.

[0049] During use, the staff connects the horizontal filter to the pipeline. Before the sewage in the pipeline enters the filter tank 1 along the diversion component 6 in the guide tube 3, the larger impurities are broken up by the diversion 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 cavity group 8 and the impurities are initially screened. The filtered water in the inner filter cavity group 8 is transported to the outside of the filter tank 1 along the guide component 4. At this time, the filter guide cylinder 47 installed in the guide component 4 filters the filtered water again to achieve multi-stage filtration of the sewage.

[0050] The staff connects the guide tube 3 to the pipeline to discharge the sewage into the guide tube 3. The diverter 62 installed in the guide tube 3 diverts the sewage. The micro motor 65 installed at the bottom of the diverter 62 drives the rotating shaft 64 and the blades 66 to rotate. At this time, the blades 66 come into contact with the sewage discharged from the diverter 62 and crush the larger impurities in the sewage to reduce the volume of the impurities and facilitate the cleaning of the filtered impurities; when the sewage is stirred by the blades 66, the rotation of the blades 66 affects the flow direction of the water, so that the sewage flows downward along the guide plate 63 into the filter tank 1.

[0051] The clamping seat 621 and the reinforcement seat 625 are installed inside the guide tube 3. When the sewage is transported to the top of the annular cover 622 along the guide tube 3, the annular cover 622 is set as an arc-shaped convex structure, so that the sewage flows to the side of the annular cover 622 and is discharged along the diversion hole 623. The annular cover 622 and the diversion hole 623 limit the flow speed of the sewage, and the sewage is diverted by reducing the sewage flow rate. The sewage enters the filter tank 1 from the diversion hole 623. Using the slow flow sedimentation principle, large particles of impurities will settle to the bottom of the filter tank 1.

[0052] After the sewage enters the filter tank 1, it is filtered through the filter cover 83 and the filter element 82 and then enters the interior of the inner tube 81. The surface of the filter cover 83 is provided with dense filter holes to filter impurities in the sewage.

[0053] The sewage in the filter tank 1 enters the cover tube 822 along the drainage groove 823 opened on the surface of the cover tube 822, and the sewage contacts the filter disc 824, which adsorbs impurities in the sewage. Then the sewage enters the guide groove 85 along the drainage groove 823 on the other side of the cover tube 822, and the sewage impurities are adsorbed and filtered through multiple groups of filter discs 824 to improve the filtration efficiency.

[0054] The filtered water in the inner tube 81 enters the diversion elbow 41 along the connecting seat 45. A filter plate is installed at the connection between the diversion elbow 41 and the positioning tube 44. The filter plate intercepts and filters impurities in the water flow, and then transports it along multiple groups of diversion elbows 41 to the filter guide tube 47. Activated carbon adsorption material is placed in the filter guide tube 47 to filter and treat the filtered water again.

[0055] After the sewage filtration is completed, the staff injects clean water into the extension tube 43 through the cleaning conduit 7 to flush the impurities intercepted and filtered in the inner filter chamber group 8. At this time, the sewage generated by cleaning and the impurities in the filter tank 1 are discharged along the discharge pipe 9 at the bottom of the filter tank 1 to facilitate subsequent cleaning of the filter, avoiding the accumulation of impurities in the filter, resulting in reduced filtration efficiency and serious blockage. Frequent replacement of filter media will not only increase the equipment maintenance cost, but may also affect the normal operation and energy efficiency of the equipment.
