Description

Technical Field

[0001] This utility model belongs to the field of filter-related technical technology, and in particular relates to a fully automatic high-pressure backwashing filter. Background Technology

[0002] An automatic high-pressure backwash filter is a device for precision filtration and automatic removal of impurities from fluid media. Its core is to trap suspended particles, pollutants and other impurities in the media through a high-precision filter screen. When the impurities trapped by the filter screen cause the inlet and outlet pressure difference to reach a set value, or when triggered by a timer controller, the system will automatically start the high-pressure backwashing mechanism. The high-pressure medium will impact the filter screen surface in the reverse direction, quickly peeling off and discharging the attached impurities. The entire process requires no manual operation and does not interrupt the operation of the main system.

[0003] However, it still has the following drawbacks in actual use: the existing fully automatic high-pressure backwash filter can only be backwashed when it is not in use, and it cannot achieve the function of cleaning while filtering during normal use, so there is still room for further optimization. Utility Model Content

[0004] The purpose of this utility model is to provide a fully automatic high-pressure backwash filter, which solves the problem that existing fully automatic high-pressure backwash filters cannot be cleaned while in use by setting up a main body component, a water supply component and a partition component.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a fully automatic high-pressure backwash filter, including a main body assembly, a water supply assembly and a separation assembly. The main body assembly includes a base, an outer cylinder is fixed on the upper surface of the base, and a filter cylinder one and a filter cylinder two are provided in the inner cavity of the outer cylinder. The outlet end of filter cylinder one passes through and protrudes from the upper end surface of the outer cylinder, and the outlet end of filter cylinder two passes through and protrudes from the upper end surface of the outer cylinder. The water supply assembly includes an inlet pipe, an outlet pipe, a drain pipe, and a backflushing pipe. The inlet pipe is a three-way water pipe with two branch pipes, namely inlet pipe one and inlet pipe two. The main pipe of the inlet pipe is inlet pipe three. Inlet pipe one and inlet pipe two are both connected to the outer cylinder peripheral wall. The partition assembly includes a partition plate 1 fixed to the center of the inner cavity of the outer cylinder, a partition plate 2 movably connected to one side of the partition plate 1, and a CNC telescopic rod fixed to the top of the outer cylinder, with the telescopic end of the CNC telescopic rod penetrating the end wall of the base and fixedly connected to the partition plate 2.

[0006] Furthermore, the water outlet fitting is a three-way water pipe, with two branch pipes being water outlet pipe one and water outlet pipe two, and the main pipe being water outlet pipe three. The water outlet pipe three is connected to the outlet end of filter cartridge one, and the water outlet pipe two is connected to the outlet end of filter cartridge two.

[0007] Furthermore, the drainage pipe fitting is a tee pipe, with two branch pipes being drainage pipe one and drainage pipe two, and the main pipe being drainage pipe three. Both drainage pipe one and drainage pipe two are connected to the outer cylinder's circumferential side wall.

[0008] Furthermore, the backwash fitting is a three-way water pipe, with two branch pipes being backwash pipe one and backwash pipe two, and the main pipe being backwash pipe three. Backwash pipe one is connected to the outlet end of filter cartridge one, backwash pipe two is connected to the outlet end of filter cartridge two, and backwash pipe three is connected to the inlet pipe three.

[0009] Furthermore, numerically controlled valves are installed on water inlet pipe 1, water inlet pipe 2, water outlet pipe 1, water outlet pipe 2, drain pipe 1, drain pipe 2, backflush pipe 1, and backflush pipe 2.

[0010] Furthermore, water passage holes are staggered on partition plate one and partition plate two, water inlet pipe one and water inlet pipe two are located on both sides of the partition assembly, and drain pipe fitting one and drain pipe fitting two are located on both sides of the partition assembly.

[0011] This utility model has the following beneficial effects: 1. This utility model, by setting up a main component, a water-passing component, and a partition component, divides the inner cavity of the outer cylinder into two independent areas, left and right, during backwashing. Then, the CNC valves of the inlet pipe 1 and outlet pipe 1 are closed, while the CNC valves of the backwash pipe 1 and drain pipe 1 are opened. At this time, the high-pressure medium in the inlet pipe 3 is divided into two paths. One path continues to flow into the right area of ​​the outer cylinder through the inlet pipe 2, passes through the filter cylinder 2 for filtration, and is discharged from the outlet pipe 2 and outlet pipe 3, ensuring that the filtration function of the main system is not interrupted. The other path of high-pressure medium flows in reverse through the backwash pipe 3 and backwash pipe 1 into the outlet end of the filter cylinder 1, impacting the inner wall of the filter screen of the filter cylinder 1 with high pressure, quickly peeling off the attached impurities. The peeled impurities and the backwashed sewage are collected in the left area of ​​the outer cylinder under high pressure, and then discharged from the system through the drain pipe 1 and drain pipe 3. The cleaning of the filter cylinder 2 is carried out in the same way, solving the problem that existing fully automatic high-pressure backwash filters cannot be cleaned while in use.

[0012] 2. The main component of this utility model has two filter cartridges inside. During normal use, the fluid entering from the inlet end can be filtered through the two filter cartridges, which greatly improves the filtration efficiency and solves the problem of low filtration efficiency of fully automatic high-pressure backwash filters.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1-5 As shown, this utility model is a fully automatic high-pressure backwash filter. The core of this filter is to achieve simultaneous filtration and backwashing through the alternating use of two filter cartridges without interrupting the operation of the main system. During use, it relies on the coordinated automatic control of the CNC valve 25 and the CNC telescopic rod 33. It includes a main component 1, a water supply component 2, and a separation component 3. The main component 1 includes a base 11, and an outer cylinder 12 is fixed on the upper surface of the base 11. The inner cavity of the outer cylinder 12 is provided with a first filter cartridge 13 and a second filter cartridge 14. The outlet end of the first filter cartridge 13 passes through and protrudes from the upper end surface of the outer cylinder 12, and the outlet end of the second filter cartridge 14 passes through and protrudes from the upper end surface of the outer cylinder 12.

[0017] In the main component 1, the base 11 provides overall support and a stable installation foundation for the outer cylinder 12 and other upper structures. The outer cylinder 12 serves as the core housing, forming a closed filtration space and providing a working environment for filter cartridge 13 and filter cartridge 2 14. Filter cartridge 13 and filter cartridge 2 14 are the core components for filtration. Their high-precision filter screens can trap suspended particles, pollutants and other impurities in the medium. The outlet ends of both are used to discharge the filtered clean medium out of the outer cylinder 12.

[0018] The water circulation assembly 2 includes an inlet pipe 21, an outlet pipe 22, a drain pipe 23, and a backwash pipe 24. The inlet pipe 21 is a three-way water pipe with two branch pipes, namely inlet pipe one 211 and inlet pipe two 212. The main pipe of the inlet pipe 21 is inlet pipe three 213. Inlet pipe one 211 and inlet pipe two 212 are both connected to the side wall of the outer cylinder 12. The water circulation assembly 2 undertakes the functions of media transportation, backwashing, and sewage discharge. The inlet pipe 21 has a three-way structure. Inlet pipe three 213 serves as the main pipe and is connected to the original medium to be filtered. Inlet pipe one 211 and inlet pipe two 212 serve as branch pipes and are connected to both sides of the outer cylinder 12 respectively, which can divert the original medium to the areas of filter cartridge one 13 and filter cartridge two 14 inside the outer cylinder 12.

[0019] The partition assembly 3 includes a partition plate 31 fixed to the center of the inner cavity of the outer cylinder 12, a partition plate 32 movably connected to one side of the partition plate 31, and a CNC telescopic rod 33 fixed to the top of the outer cylinder 12. The telescopic end of the CNC telescopic rod 33 passes through the end wall of the base 11 and is fixedly connected to the partition plate 32. The partition assembly is used to achieve flexible isolation of the internal space of the outer cylinder 12. The partition plate 31 is fixed to the center of the inner cavity of the outer cylinder 12 as a basic partition structure. The partition plate 32 is movably connected to the partition plate 31. The surfaces of the two are provided with staggered water passage holes. The connection state of the two sides of the outer cylinder 12 can be controlled by adjusting the position. The telescopic end of the CNC telescopic rod 33 is fixed to the partition plate 32 and can drive the partition plate 32 to move along the surface of the partition plate 31. By adjusting the alignment or staggering of the water passage holes of the two, the independence or connection of the two sides of the outer cylinder 12 can be achieved, providing space conditions for the alternating operation of the two filter cartridges.

[0020] Furthermore, the water outlet fitting 22 is a three-way water pipe. The two branch pipes of the water outlet fitting 22 are water outlet pipe one 221 and water outlet pipe two 222, respectively. The main pipe of the water outlet fitting 22 is water outlet pipe three 223. Water outlet pipe one 221 is connected to the outlet end of filter cartridge one 13, and water outlet pipe two 222 is connected to the outlet end of filter cartridge two 14. The water outlet fitting 22 is also a three-way structure. Water outlet pipe one 221 and water outlet pipe two 222 are respectively connected to the outlet ends of filter cartridge one 13 and filter cartridge two 14, and are used to collect the clean media filtered by the two filter cartridges, and then discharge them through the main pipe of water outlet pipe three 223.

[0021] Furthermore, the drain fitting 23 is a tee pipe, with two branch pipes being drain pipe one 231 and drain pipe two 232, and the main pipe of the drain fitting 23 being drain pipe three 233. Drain pipe one 231 and drain pipe two 232 are both connected to the side wall of the outer cylinder 12. The drain fitting 23 is still a tee structure. Drain pipe one 231 and drain pipe two 232 are set in the areas on both sides of the outer cylinder 12 to discharge the impurities and sewage stripped off during the backwashing process, and finally discharged from the system through the main pipe of drain pipe three 233.

[0022] Furthermore, the backwash fitting 24 is a three-way water pipe. The two branch pipes of the backwash fitting 24 are backwash pipe one 241 and backwash pipe two 242, respectively. The main pipe of the backwash fitting 24 is backwash pipe three 243. Backwash pipe one 241 is connected to the outlet end of filter cartridge one 13. Backwash pipe two 242 is connected to the outlet end of filter cartridge two 14. Backwash pipe three 243 is connected to water inlet pipe three 213. The backwash fitting 24 is still a three-way structure. Backwash pipe three 243 is connected to water inlet pipe three 213, which can introduce high-pressure medium. Backwash pipe one 241 and backwash pipe two 242 are connected to the outlet ends of filter cartridge one 13 and filter cartridge two 14, respectively, which can reverse the flow of high-pressure medium into the filter cartridge to achieve backwashing of the filter screen.

[0023] Furthermore, each of the following pipes is equipped with a numerically controlled valve 25: inlet pipe 211, inlet pipe 212, outlet pipe 221, outlet pipe 222, drain pipe 231, drain pipe 232, backwash pipe 241, and backwash pipe 242. The numerically controlled valve 25 can automatically switch the on / off state of each pipe and is a key control component for switching between filtration and backwashing modes.

[0024] Furthermore, water passage holes are staggered on partition plate 1 31 and partition plate 2 32, water inlet pipe 1 211 and water inlet pipe 212 are arranged on both sides of partition component 3, and drain pipe 1 and drain pipe 232 are arranged on both sides of partition component 3. By aligning or staggering the water passage holes of the two, the independent or connected areas on both sides of the outer cylinder 12 can be realized, providing space for the alternating operation of the two filter cartridges.

[0025] The specific working principle of this utility model is as follows: In the initial state, the CNC telescopic rod 33 drives the partition plate 2 32 to move, so that the partition plate 2 32 and the staggered water passage holes of the partition plate 1 31 are completely fitted together, and the inner cavity of the outer cylinder 12 is a whole area. At this time, the CNC valves 25 of the water inlet pipe 3 213, water inlet pipe 1 211, water inlet pipe 2 212, water outlet pipe 1 221, water outlet pipe 2 222 and water outlet pipe 3 223 are opened, and all CNC valves 25 of the backflushing pipe fitting 24 and the drain pipe fitting 23 are closed. After a while... After the high-pressure filter medium enters through inlet pipe 3 213, it flows into the left and right sides of the outer cylinder 12 through inlet pipe 1 211 and inlet pipe 2 212 respectively. Then the medium passes through the high-precision filter screens of filter cylinder 1 13 and filter cylinder 2 14. Suspended particles, pollutants and other impurities are intercepted by the filter screens. The filtered clean medium flows out from the outlet end of filter cylinder 1 13 and filter cylinder 2 14, and is collected through outlet pipe 1 221 and outlet pipe 2 222 to outlet pipe 3 223, and finally discharged into the main system, realizing synchronous filtration of dual filter cylinders.

[0026] When the filter screen of filter cartridge 13 traps too many impurities, causing the pressure difference between its inlet and outlet to reach the set value, the system automatically starts the backwashing program. The CNC telescopic rod 33 drives the partition plate 2 32 to move, so that the staggered water passages of partition plate 2 32 and partition plate 1 31 are completely misaligned. The inner cavity of the outer cylinder 12 is divided into two independent areas, corresponding to the working spaces of filter cartridge 13 and filter cartridge 2 14, respectively. Then, the CNC valves 25 of inlet pipe 1 211 and outlet pipe 1 221 are closed, while the CNC valves 25 of backwash pipe 1 241 and drain pipe 1 231 are opened. At this time, the inlet pipe 3 213... The high-pressure medium is divided into two paths. One path continues to flow into the right side area of ​​the outer cylinder 12 through the inlet pipe 212, passes through the filter cylinder 214 for filtration, and is discharged from the outlet pipe 222 and outlet pipe 323 to ensure that the filtration function of the main system is not interrupted. The other path of high-pressure medium flows in the opposite direction into the outlet end of the filter cylinder 13 through the backwash pipe 3243 and backwash pipe 1241. It impacts the inner wall of the filter screen of the filter cylinder 13 with high pressure, which quickly peels off the attached impurities. The peeled impurities and the backwashed sewage are collected in the left side area of ​​the outer cylinder 12 under high pressure, and then discharged from the system through the drain pipe 1231 and drain pipe 3233.

[0027] After backwashing of filter cartridge 13 is completed, the system closes the CNC valve 25 of backwash pipe 1241 and drain pipe 1231, and reopens the CNC valve 25 of inlet pipe 1211 and outlet pipe 1221. Filter cartridge 13 resumes its filtration function. If filter cartridge 24 needs backwashing subsequently, the operation procedure is the same as that of filter cartridge 13: close the CNC valve 25 of inlet pipe 212 and outlet pipe 222, and open the CNC valve 25 of backwash pipe 242 and drain pipe 232. The high-pressure medium from inlet pipe 313 backwashes filter cartridge 244 through backwash pipe 242, and the wastewater is discharged from drain pipe 232. Meanwhile, filter cartridge 13 continues normal filtration. Throughout the process, the CNC components precisely control the pipeline opening and closing and the position of the partition plate, realizing the automated alternation of filtration and backwashing.

[0028] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
