Description

Technical Field

[0001] This utility model relates to the field of deep filtration technology for tap water, specifically a deep filtration device for tap water. Background Technology

[0002] A deep water filter is a device used for the deep purification of tap water. One type is a fully automatic self-cleaning filter, which consists of main components such as a drive mechanism, control piping, main pipe assembly, filter element assembly, cleaning mechanism, and connecting flanges. The default filtration accuracy is 100 microns, adjustable from 100 to 10000 microns. It typically uses filter media with a specific porous structure, such as activated carbon or fibers. When tap water passes through these filter media, suspended particles, colloids, bacteria, and other impurities are trapped by the pores of the filter media, thus purifying the water.

[0003] The aforementioned and existing related technologies often have the following drawbacks: tap water is filtered by the filter inside the inlet and then discharged from the outlet pipe, which is connected to the connecting pipe via a flange. Therefore, during the overall maintenance and replacement of the equipment, it is necessary to remove the outlet pipe and the connecting pipe by means of the flange. During the disassembly and assembly process, the flange relies on manual lifting or auxiliary support for positioning, and the bolt holes need to be repeatedly adjusted in angle to be aligned. Moreover, the hole position is easily deviated due to hand shaking. The installation accuracy depends on experience. Without auxiliary positioning, the coaxiality of the bolt holes is entirely controlled by the installer's feel, which can easily lead to illegal operations such as forcibly inserting a single bolt, causing flange deformation or uneven bolt stress. Long-term operation poses a risk of loosening and leakage and results in a significant waste of time.

[0004] Therefore, we propose a deep filtration device for tap water. Summary of the Invention

[0005] The purpose of this invention is to provide a deep filtration device for tap water to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deep filtration device for tap water, comprising a filter, a housing mounted on the arc surface of the filter, a drive mechanism mounted on the upper surface of the filter, an inlet connected to the arc surface of the filter, an outlet pipe connected to the arc surface of the filter on the other side relative to the inlet, a drain pipe connected to the lower surface of the filter, a flange fixedly connected to the end of the outlet pipe away from the filter, a plurality of screw holes evenly provided on one side of the flange, two connecting plates fixedly connected to the arc surface of the outlet pipe, the sides of the two connecting plates close to each other being fixedly connected to the outlet pipe, a support plate fixedly connected to the lower surface of the connecting plate, the two support plates located on the arc surface of the flange, a vertical plate fixedly connected to the inner wall of the support plate, a positioning rod slidably passing through one side of the vertical plate, the arc surface of the positioning rod slidably connected to the inner wall of the screw hole, and a circular plate fixedly connected to the end of the positioning rod away from the flange.

[0007] The aforementioned components achieve the following effect: they enable quick and precise alignment between the flange and bolts of the deep water filter, thereby minimizing difficulties in installing the flange and positioning the bolts during filter maintenance and replacement, reducing overall work efficiency and preventing problems that could affect the use of the deep water filter.

[0008] Preferably, the inner wall of the support plate is provided with an enlarged hole, which is located on the arc surface of the flange.

[0010] Preferably, the arc surface of the positioning rod is fitted with a spring, and the two ends of the spring are fixedly connected to the vertical plate and the circular plate, respectively.

[0011] The effect achieved by the above components is that pulling the circular plate causes the spring to unfold, and the spring achieves the effect of automatically moving the positioning rod.

[0012] Preferably, a pull ring is fixedly connected to the side of the circular plate away from the spring, and the pull ring has a semi-circular cross-section.

[0013] The effect achieved by the above components is that pulling the pull ring moves the positioning rod with the help of the circular plate, and the pull ring plays a better role in pulling the positioning rod.

[0014] Preferably, an L-shaped rod is fixedly connected to one side of the support plate, and the short arm of the L-shaped rod is slidably connected to the inner wall of the pull ring.

[0015] The effect achieved by the above components is that the pull ring drives the positioning rod to fit onto the short arm of the L-shaped rod, and the L-shaped rod achieves the effect of a temporary limiting positioning rod.

[0016] Preferably, a trapezoidal block is fixedly connected to the end of the positioning rod away from the circular plate, and the arc surface of the trapezoidal block is slidably connected to the inner wall of the screw hole.

[0017] The effect achieved by the above components is that the positioning rod is inserted into the screw hole with the help of the trapezoidal block, and the trapezoidal block plays the role of quickly positioning the positioning rod and the screw hole.

[0018] Preferably, the arc dimension of the positioning rod is adapted to the inner wall dimension of the screw hole.

[0019] The effect achieved by the above-mentioned components is to further reduce the micro-deviation between screw holes by using a positioning rod whose arc size matches the inner wall size of the screw hole.

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the support plate and the vertical plate, achieves the effect of rapid and accurate alignment between the flange and bolts of the deep water filter, which can effectively eliminate the slight deflection during pipeline installation, ensure that all bolt holes are inserted at one time, improve installation efficiency, significantly improve the effect in high-frequency maintenance scenarios, and greatly reduce the technical threshold for installation.

This innovation solves the pain points of traditional flange connection alignment difficulties, easy damage, and reliance on experience with mechanical structure, and has both low cost modification and high practicality, which is in line with the design trend of industrial equipment installation and low maintenance.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a deep filtration device for tap water, including a filter 1, a housing 2 mounted on the arc surface of the filter 1, a drive mechanism 3 mounted on the upper surface of the filter 1, an inlet 4 connected to the arc surface of the filter 1, an outlet pipe 5 connected to the arc surface of the filter 1 opposite to the inlet 4, a drain pipe 6 connected to the lower surface of the filter 1, a flange 7 fixedly connected to the end of the outlet pipe 5 away from the filter 1, a plurality of screw holes 8 evenly distributed on one side of the flange 7, and two connecting plates 9 fixedly connected to the arc surface of the outlet pipe 5, with the sides of the two connecting plates 9 close to each other connected to the outlet pipe. 5. Fixed connection: A support plate 10 is fixedly connected to the lower surface of the connecting plate 9. Two support plates 10 are located on the arc surface of the flange 7. A vertical plate 11 is fixedly connected to the inner wall of the support plate 10. A positioning rod 12 slides through one side of the vertical plate 11. The arc surface of the positioning rod 12 is slidably connected to the inner wall of the bolt hole 8. A circular plate 13 is fixedly connected to the end of the positioning rod 12 away from the flange 7. This achieves the effect of quick and accurate alignment between the flange 7 and the bolts of the deep water filter 1, thereby minimizing the difficulty in installing the flange 7 and positioning the bolts when maintaining and replacing the filter 1, reducing the overall work efficiency and causing problems that affect the use of the deep water filter.

[0028] like Figure 2 and Figure 3 as well as Figure 4 As shown, the inner wall of the support plate 10 has an enlarged hole 14, which is located on the arc surface of the flange 7. The bolt is inserted into the screw hole 8 at the position of the enlarged hole 14. The enlarged hole 14 facilitates the installation of bolts at the support plate 10. The arc surface of the positioning rod 12 is fitted with a spring 15. The two ends of the spring 15 are fixedly connected to the vertical plate 11 and the circular plate 13, respectively. Pulling the circular plate 13 causes the spring 15 to unfold, and the spring 15 achieves the effect of automatically moving the positioning rod 12. A pull ring 16 is fixedly connected to the side of the circular plate 13 away from the spring 15. The cross-section of the pull ring 16 is semi-circular. Pulling the pull ring 16 drives the positioning rod 12 to move with the help of the circular plate 13. The pull ring 16 plays a better role in pulling the positioning rod 12.

[0029] An L-shaped rod 17 is fixedly connected to one side of the support plate 10. The short arm of the L-shaped rod 17 is slidably connected to the inner wall of the pull ring 16. The pull ring 16 drives the positioning rod 12 to be sleeved on the short arm of the L-shaped rod 17. The L-shaped rod 17 achieves the effect of temporarily limiting the positioning rod 12. A trapezoidal block 18 is fixedly connected to the end of the positioning rod 12 away from the circular plate 13. The arc surface of the trapezoidal block 18 is slidably connected to the inner wall of the screw hole 8. The positioning rod 12 is inserted into the screw hole 8 with the help of the trapezoidal block 18. The trapezoidal block 18 plays the role of quickly positioning the positioning rod 12 and the screw hole 8. The arc size of the positioning rod 12 is adapted to the inner wall size of the screw hole 8. The positioning rod 12, whose arc size is adapted to the inner wall size of the screw hole 8, achieves the effect of further reducing the slight deviation between the screw holes 8.

[0030] Working principle: When deep filtration of tap water is required, first move the connecting pipe between the two support plates 10, then move the connecting pipe until it is in contact with the flange 7. At this time, the connecting pipe is located in the enlarged hole 14. Then move the pull ring 16 to disengage from the short arm of the L-shaped rod 17. The L-shaped rod 17 achieves the effect of temporarily limiting the positioning rod 12. At this time, the spring 15 is in a contracted state, and the spring 15 achieves the effect of automatically moving the positioning rod 12. With the help of the vertical plate 11, the circular plate 13 moves, and the positioning rod 12 slides through the circular plate 13 from the vertical plate 11. The positioning rod 12 is then inserted into the screw hole 8 of the flange 7 with the help of the trapezoidal block 18. The trapezoidal block 18 plays the role of quickly positioning the positioning rod 12 and the screw hole 8. At this time, slightly rotate the connecting pipe. Once the screw hole 8 of the flange 7 of the connecting pipe is aligned, the positioning rod 12 is again inserted into the screw hole 8 through the trapezoidal block 18 with the help of the contraction of the spring 15. The positioning rod 12, whose arc size is adapted to the inner wall size of the screw hole 8, achieves the effect of further reducing the slight deviation between the screw holes 8. Align the flange 7 and screw holes 8 of water pipe 5 to allow for bolt installation until the bolts are installed into the screw holes 8 of positioning rod 12. Then, pull the pull ring 16 onto the short arm of L-shaped rod 17. The pull ring 16 helps to better pull the positioning rod 12. At this time, spring 15 is in a stretched state. After the positioning rod 12 moves out of the screw holes 8, install the remaining two screw holes 8 using the enlarged hole 14. The enlarged hole 14 facilitates the installation of bolts at the support plate 10. By positioning the positioning rod 12 and the support plate 10, slight deflection during pipe installation can be effectively eliminated, ensuring that all bolt holes are inserted at once, improving installation efficiency. Then, start filter 1 through the housing 2. After tap water enters filter 1 through inlet 4, the filter element assembly in filter 1 performs deep filtration of tap water. The drive mechanism 3 can also drive the cleaning mechanism in filter 1 to automatically clean the filter element assembly, improving the deep filtration quality of tap water. After filtration, tap water enters the connecting pipe through outlet pipe 5, while impurities are discharged through drain pipe 6.
