Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for water supply and drainage, and in particular to an anti-clogging device for building water supply and drainage. Background Technology

[0002] Water supply and drainage science and engineering studies the social cycle of water. On the one hand, it is about "water supply," which involves purifying natural water drawn from rivers and lakes into tap water that meets domestic water standards and then delivering it to households. On the other hand, it is about "drainage," which involves treating used sewage and wastewater and then discharging it cleanly into rivers and lakes. It is an important structure in current building engineering.

[0003] Pipe blockage is a common problem in building water supply and drainage systems, especially when dealing with sewage containing fibers, solid particles, or grease. Traditional filtration devices often have the following limitations: when conventional filtration equipment becomes clogged, the system needs to be shut down for cleaning, interrupting drainage and affecting the normal use of the building; most systems rely on manual physical unblocking or chemical dissolution, lacking a bypass channel design for quick switching, making it difficult to cope with sudden severe blockages, and unable to guarantee continuous system operation during maintenance.

[0004] Therefore, it is necessary to provide an anti-clogging device for building water supply and drainage to solve the above-mentioned technical problems. Utility Model Content

[0026] A blockage prevention device for building water supply and drainage includes: an inlet pipe 1, a first outlet pipe 2, and a second outlet pipe 11. A first control valve 3 and a second control valve 4 are respectively provided at the upper and lower parts of the first outlet pipe 2. A processing chamber 5 is provided between the first outlet pipe 2 and the inlet pipe 1. The processing chamber 5 is located between the first control valve 3 and the second control valve 4. An installation groove 6 is provided on the processing chamber 5. A filter assembly 7 is provided inside the processing chamber 5. A pressing part 8 is provided on the outside of the processing chamber 5. A crushing blade assembly 9 is provided on the upper part of the filter assembly 7. A fixing blade assembly 10 is fixedly connected to the inner wall of the processing chamber 5. The upper and lower ends of the second outlet pipe 11 are fixedly connected to the lower ends of the inlet pipe 1 and the first outlet pipe 2, respectively. A third control valve 12 is provided at the upper end of the second outlet pipe 11. An auxiliary unblocking part 13 is provided above the second control valve 4.

[0027] By using the diversion design of the inlet pipe 1 with the first outlet pipe 2 and the second outlet pipe 11, and in conjunction with the layout of multiple control valves including the first control valve 3, the second control valve 4 and the third control valve 12, the filtration area can be quickly isolated when the treatment room 5 is blocked and requires maintenance, forming a bypass channel to ensure continuous system operation. The treatment room 5 crushes foreign objects before outputting them as water flows through it, preventing subsequent pipe blockage. The crushing blade assembly 9 and the fixed blade assembly 10 are used to crush foreign objects, and the auxiliary unblocking part 13 blows the foreign objects stuck on the filter assembly 7 upwards and crushes them, reducing the possibility of the filter assembly 7 becoming blocked after long-term operation and affecting the normal filtration function.

[0028] The filter assembly 7 includes an arc-shaped cover plate 71, a filter screen 72, a positioning block 74, and a sealing ring 75. The arc-shaped cover plate 71 is rotatably connected to the mounting groove 6. The filter screen 72 has a positioning groove 73 on its outer side, and the positioning groove 73 corresponds to the positioning block 74.

[0029] The curved cover plate 71 is rotatably connected for easy opening and closing. The positioning groove 73 and the positioning block 74 cooperate to ensure the precise positioning of the filter screen 72. The modular design supports quick removal of the filter screen 72 for maintenance and cleaning, shortening maintenance downtime.

[0030] The pressing part 8 includes an annular pressing member 81, a first sliding groove 82, a second sliding groove 83, and a buckle 84. The first sliding groove 82 is located below the mounting groove 6, and the second sliding groove 83 is located on the processing chamber 5 on the side away from the first sliding groove 82. The annular pressing member 81 is slidably connected to the first sliding groove 82 and the second sliding groove 83 respectively. The two sides of the annular pressing member 81 are rotatably connected to the locking blocks 85, and the locking blocks 85 correspond to the buckles 84.

[0031] The annular clamping element 81 applies uniform pressure to the arc-shaped cover plate 71, and the snap-locking mechanism provides tactile feedback to ensure proper operation. The feature of not requiring complicated tools for disassembly and assembly improves maintenance efficiency.

[0032] The crushing blade assembly 9 includes a drive motor 91, and a rotating shaft 92 is provided at the output end of the drive motor 91. Two sets of sleeves 93 are fixedly connected to the rotating shaft 92, and multiple sets of equidistantly distributed crushing blades 94 are fixedly connected to the sleeves 93.

[0033] The multi-angled, staggered crushing blades 94 form a three-dimensional cutting network, and the equidistant arrangement design ensures uniform crushing of materials and prevents local overload.

[0034] The fixed blade assembly 10 includes a connecting seat 101, which is fixedly connected to the inner wall of the processing chamber 5. A symmetrically distributed fixed blade group 102 is fixedly connected to the connecting seat 101. The fixed blade group 102 is staggered with the crushing blade 94. A reinforcing plate 103 is fixedly connected between the fixed blade groups 102.

[0035] The symmetrical blade assembly and the movable blade form a shearing crushing process, which improves the crushing efficiency of blockages. The reinforcing plate 103 improves the impact resistance of the fixed blade assembly 10, and the staggered layout generates a turbulence effect, which increases the probability of secondary crushing of materials.

[0036] The auxiliary unblocking unit 13 includes an air blowing pipe 131, on which an air valve 132 is provided, and the end of the air blowing pipe 131 is connected to the bottom of the filter assembly 7.

[0037] The gas impact design enables non-contact unblocking, which can push the blockages in the filter screen upwards, where they are crushed by the crushing blades and the fixed blade assembly, effectively removing the sediment at the bottom of the filter screen.

[0038] The working principle of the anti-clogging device for building water supply and drainage provided by this utility model is as follows:

[0039] By using the diversion design of the inlet pipe 1 with the first outlet pipe 2 and the second outlet pipe 11, and in conjunction with the layout of multiple control valves including the first control valve 3, the second control valve 4 and the third control valve 12, the filtration area can be quickly isolated when the treatment room 5 is blocked and requires maintenance, forming a bypass channel to ensure continuous system operation. The treatment room 5 crushes foreign objects before outputting them as water flows through it, preventing subsequent pipe blockage. The crushing blade assembly 9 and the fixed blade assembly 10 are used to crush foreign objects, and the auxiliary unblocking part 13 blows the foreign objects stuck on the filter assembly 7 upwards and crushes them, reducing the possibility of the filter assembly 7 becoming blocked after long-term operation and affecting the normal filtration function.

[0040] Compared with related technologies, the anti-clogging device for building water supply and drainage provided by this utility model has the following beneficial effects:

[0041] When a blockage occurs in the processing room 5 and maintenance is required, the filtration area can be quickly isolated. The second output pipe 11 forms a bypass channel to ensure continuous system operation and improve system flexibility and emergency response capabilities. The crushing blade assembly 9 and the fixed blade assembly 10 are staggered to improve the ability to handle blockages. The auxiliary unblocking section 13 blows the foreign objects stuck on the filter assembly 7 upwards and crushes them, reducing the probability of blockage in the filter assembly 7.
