Description

Technical Field

[0001] The invention relates to water treatment equipment, and more specifically to a water filtering and purifying component, and also to a sewage filtering and purifying system having the water filtering and purifying component. Background Art

[0002] Industrial wastewater usually contains a large amount of impurities and harmful substances. It is necessary to purify the wastewater during treatment. Through multiple treatment processes such as filtration separation, harmful substance treatment, and degradation, the wastewater can meet the discharge standards or form recyclable recycled water. The filtration and separation of wastewater is the most critical part of the wastewater treatment process. Most of the impurities and pollutants can be removed through filtration. Among them, fiber membrane filtration is a commonly used filtration equipment, which uses hollow filter fibers as filtration modules. Compared with traditional filter membranes, hollow filter fibers have a larger specific surface area and can improve the filtration efficiency.

[0003] The hollow filter fiber assembly usually has an upper tube body, a lower tube body and a plurality of hollow filter fibers. The upper tube body and the lower tube body are in a structure that is distributed in parallel up and down. The upper and lower ends of the hollow filter fiber are respectively connected to the upper tube body and the lower tube body, and interfaces are installed on the upper and lower tube bodies. By applying negative pressure suction to the interface between the upper and lower tube bodies, a negative pressure suction effect can be generated in the hollow filter fiber. Outside the hollow filter fiber, relatively clean water can enter the tube cavity from the tiny holes on the outside of the hollow filter fiber, and then flow out to the upper and lower ends of the hollow filter fiber to achieve sewage filtration treatment.

[0004] Due to the negative pressure adsorption force at the upper and lower ends of the hollow filter fiber, the water in the lumen near the upper end of the hollow filter fiber usually flows upward, and the water in the lumen near the lower end usually flows downward. The water flow near the two ends is relatively faster, and the lumen near the middle section of the hollow filter fiber is in a relatively balanced state due to the relatively close suction effects at the upper and lower ends. This results in a lower flow rate in the middle section of the hollow filter fiber, which leads to poor flow of part of the middle section of the hollow filter fiber, and tiny particles gather in the lumen to cause blockage.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] This embodiment discloses a water purification component, referring to Figure 1-Figure 5 As shown, it includes a frame 1 and several water filter components. The frame 1 can support the water filter components, and the filtering part of the water filter components is mainly hollow filter fibers 23, which can filter and treat sewage to achieve sewage purification.

[0035] Reference Figure 1 , Figure 2 and Figure 3 As shown, the frame 1 includes an upper support frame 11, a lower support frame 13 and a connecting frame 12, wherein the lower support frame 13 is located at the lower side of the upper support frame 11, wherein the upper support frame 11 and the lower support frame 13 are both quadrilateral frame structures, and the upper support frame 11 and the lower support frame 13 are connected and fixed by the connecting frame 12.

[0036] Reference Figure 2 As shown, the water filter assembly includes an upper tube body 21, a lower tube body 22 and a plurality of hollow filter fibers 23. The upper tube body 21 is fixedly mounted on the frame 1, and the upper tube body 21 is specifically fixedly mounted on the upper support frame 11. The lower tube body 22 is located at the lower side of the upper tube body 21, the upper end of the hollow filter fiber 23 is connected to the upper tube body 21, and the lower end of the hollow filter fiber 23 is connected to the lower tube body 22.

[0037] The upper tube body 21 is provided with an upper interface 211, and the lower tube body 22 is provided with a lower interface 221. The upper interface 211 can be connected to an external water suction pipe, and the lower interface 221 can also be connected to an external water suction pipe, and negative pressure can be formed in the hollow filter fiber 23 through the upper interface 211 and the lower interface 221. The hollow filter fiber 23 is immersed in the sewage, and the particulate impurities in the sewage can be blocked outside the hollow filter fiber 23, and relatively clean water can be sucked into the inner cavity of the hollow filter fiber 23, thereby realizing the filtration and separation of sewage.

[0038] In addition, the water purification assembly further includes an adjustment rod 3 and a counterweight frame 31. The adjustment rod 3 is mounted on the counterweight frame 31. The adjustment rod 3 is arranged transversely. The middle section of the hollow filter fiber 23 is wound outside the adjustment rod 3 and forms a winding portion 231. The hollow filter fiber 23 is wound 1-2 times. Figure 4 shown.

[0039] The lower tube body 22 can be adjusted up and down. When the lower tube body 22 is adjusted downward, the hollow filter fiber 23 can be tensioned up and down. After the hollow filter fiber 23 is tensioned, the winding portion 231 of the hollow filter fiber 23 is pressed against the adjusting rod 3. After the winding portion 231 of the compressed hollow filter fiber 23, the fiber cavity will be flattened, and the upper end 232 and the lower end 233 of the hollow filter fiber 23 can be blocked.

[0040] After the middle section of the hollow filter fiber 23 can be blocked, the upper and lower sections will not circulate with each other. The water flow of the upper section of the hollow filter fiber 23 can flow upward and flow out from the upper interface 211 of the upper tube body 21, and the water flow of the lower section can flow downward and flow out from the lower interface 221 of the lower tube body 22, thereby achieving water flow in the upper and lower sections of the hollow filter fiber 23. Since the upper and lower sections have only one outlet, each section of the inner cavity of the hollow filter fiber 23 has water flow, which will not cause a section of the hollow filter fiber 23 to stay for a long time and cause the problem of stopping and blocking.

[0041] The adjusting rod 3 can be adjusted up and down. During the adjustment process, the winding portion 231 of the hollow filter fiber 23 follows the adjustment rod 3 to adjust up and down, thereby changing the boundary point between the upper half and the lower half of the hollow filter fiber 23. The upper part of the winding portion 231 of the hollow filter fiber 23 is the upper half, and the lower part is the lower half.

[0042] During the adjustment process, the lower tube body 22 can generally be adjusted upward to loosen the hollow filter fiber 23, so that the winding portion 23 of the hollow filter fiber 23 outside the adjustment rod 3 can be in a relaxed state, so that it can be adjusted up and down smoothly.

[0043] Specifically, the upper tube body 21 and the lower tube body 22 are arranged horizontally and in parallel, and the hollow filter fibers 23 are oriented vertically, and the upper tube body 21 and the lower tube body 22 can be connected through the hollow filter fibers 23. When the hollow filter fibers 23 are in a relaxed state, the winding portion 231 of the hollow filter fibers 23 is also in a relaxed state, and water can flow through the hollow filter fibers 23.

[0044] Reference Figure 3 As shown, a plurality of groups of hollow filter fibers 23 are arranged between the upper tube body 21 and the lower tube body 22, and each group of hollow filter fibers 23 is evenly distributed at intervals.

[0045] The adjusting rod 3 is also horizontal and arranged in parallel with the upper tube body 21 and the lower tube body 22. The adjusting rod 3 passes through the winding part 231 of each group of hollow filter fibers 23. The hollow filter fibers 23 in the same group of water filter components are all wound outside the adjusting rod 3, and the winding direction is consistent. The outer periphery of the adjusting rod 3 is a circular tubular structure, and the outer peripheral surface of the adjusting rod 3 is relatively smooth, so that the adjusting rod 3 can move smoothly during the lifting and lowering adjustment process.

[0046] Reference Figure 1 , Figure 2 As shown, the counterweight frame 31 is a frame structure, surrounding the outer periphery of the frame 1. The counterweight frame 31 includes two adjustment cross bars 311 and two adjustment auxiliary bars 312, the two adjustment cross bars 311 are arranged opposite to each other, the two adjustment auxiliary bars 312 are also arranged opposite to each other, and the four bars are fixedly connected to form a quadrilateral frame.

[0047] Both ends of the adjusting rod 3 are respectively mounted on the counterweight frame 31 , and the deadweight of the counterweight frame 31 can counterweight the adjusting rod 3 downward to keep the upper half of the hollow filter fiber 23 taut.

[0048] Linkage seats 300 are installed at both ends of the adjustment rod 3. The linkage seats 300 are fixedly connected to the counterweight frame 31 and fixedly installed on the adjustment cross bar 311. Each adjustment rod 3 can be supported by the adjustment cross bar 311.

[0049] Reference Figure 5 As shown, a linkage cavity 301 is provided in the linkage seat 300, and a linkage slot 302 extending upward and downward is provided on the outer side of the linkage seat 300, and the linkage slot 302 is provided toward the direction of the adjustment rod 3. The size of the linkage slot 302 is adapted to the adjustment rod 3, and the adjustment rod 3 can be adjusted upward and downward in the linkage slot 302.

[0050] A vertically extending slide groove 303 is provided on the inner wall of the linkage cavity 301, and a slide seat 308 is slidably connected in the slide groove 303. A support shaft 307 is fixedly connected to the end of the adjustment rod 3, and the support shaft 307 is rotatably connected to the slide seat 308 through a bearing 309. On the one hand, the adjustment rod 3 can be supported for rotation, and on the other hand, the adjustment rod 3 can be guided to slide up and down.

[0051] The counterweight frame 31 can be adjusted up and down, and a guide structure is provided between the counterweight frame 31 and the frame 1, so that the counterweight frame 31 can slide up and down smoothly.

[0052] When the counterweight frame 31 is adjusted upward, the counterweight frame 31 can move up and down relative to the adjusting rod 3 and the end of the adjusting rod 3. The lower end of the slide groove 303 abuts against the slide seat 308, which can press and drive the adjusting rod 3 to move upward, thereby driving the adjusting rod 3 to move upward.

[0053] The position where the adjusting rod 3 extends into the linkage chamber 301 is coaxially fixedly connected with a gear 306. The upper inner part of the linkage chamber 301 is fixedly connected with a limit block 304, and the lower side of the limit block 304 is provided with a limit tooth 305, which can be snap-fitted with the gear 306.

[0054] When the counterweight frame 31 is adjusted downward, that is, when the deadweight of the counterweight frame 31 decreases, it tends to move downward. When the hollow filter fiber 23 is in tension, the hollow filter fiber 23 and the adjustment rod 3 will be in a state of friction tension and limit. When the counterweight frame 31 moves downward, the limit teeth 305 and the gear 306 can be engaged, thereby maintaining the adjustment rod 3, the linkage seat 300 and the counterweight frame 31 in a relatively fixed state.

[0055] When the counterweight frame 31 is adjusted upward, the counterweight frame 31 is adjusted upward, the adjusting rod 3 is limited by the hollow filter fiber 23, the linkage seat 300 of the counterweight frame 31 can be adjusted upward relative to the adjusting rod 3 (the gear 306 at the end of the adjusting rod 3), and the limiting teeth 305 and the gear 306 can be disengaged from each other, so that the adjusting rod 3 can rotate adaptively. When the counterweight frame 31 is adjusted upward, the limiting teeth 305 and the gear 306 can be disengaged from each other, the adjusting rod 3 can rotate freely, and the adjusting rod 3 and the hollow filter fiber 23 are in a state of rolling activity with each other. The contact position between the hollow filter fiber 23 and the adjusting rod 3 is relatively rolling, and its friction is less than the relative slippage, so that the adjusting rod 3 and the hollow filter fiber 23 can smoothly move up and down.

[0056] Reference Figure 1 , Figure 2As shown, several water filter assemblies are evenly arranged in the horizontal direction, and the hollow filter fibers 23 in each group of water filter assemblies form a roughly rectangular array distribution structure. A lower connecting rod 222 is installed and fixed between the lower tubes 22 of each water filter assembly, and the lower tubes 22 of the water filter assembly can be fixed as a whole through the lower connecting rod 222, so that the lower tubes 22 of each water filter assembly can maintain a synchronous active state.

[0057] The lower tube body 22 of the water filter assembly is raised and lowered by a lifting assembly. The lifting assembly is located at the lower part of the lower tube body 22 of the water filter assembly, and the lifting assembly includes a lifting support frame that can be raised and lowered. The lifting support frame supports the lower tube body 22 and the lower connecting rod 222 by pressing. When the lifting support frame rises, it can push the lower tube body 22 and the lower connecting rod 222 to move upward, and when it falls, it can make the lower tube body 22 and the lower connecting rod 222 move downward, thereby making the hollow filter fiber 23 stretched and tensioned.

[0058] The present embodiment also discloses a sewage filtration and purification system, including the water filtration and purification component as described above, and also including a container for accommodating sewage, the water filtration and purification component being installed in the container; and the hollow filter fiber 23 of the water filtration and purification component is immersed in the sewage in the container, thereby being able to purify the sewage.

[0059] In this embodiment, the sewage filtration and purification system also includes two negative pressure self-priming water pipes, which are respectively connected to the upper interface 211 and the lower interface 221, so that water can flow out, thereby realizing sewage self-priming purification and filtration treatment.

[0060] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
