Technical Field

[0001] This utility model relates to the field of wastewater pretreatment technology, specifically to a wastewater pretreatment device for water supply and drainage pipelines. Background Technology

[0002] Wastewater pretreatment is the starting point of the wastewater treatment process. Its main purpose is to remove harmful substances such as suspended solids, oils, and heavy metals from wastewater through physical, chemical, or biological means, creating favorable conditions for subsequent treatment (such as biochemical treatment). In wastewater pretreatment, water supply and drainage pipelines mainly refer to the pipe network system used to collect and transport wastewater, including main pipes, branch pipes, and inspection wells. Its core function is to transport wastewater to the wastewater treatment plant for treatment.

[0003] The existing technology also has the following shortcomings. When pre-treating sewage in water supply and drainage pipelines, it is necessary to filter out large-volume impurities. Therefore, a bar screen is used for blocking. However, the existing bar screen is not easy to install and cannot effectively clean impurities attached to the surface. Long-term use can easily cause blockage at the water inlet and reduce the water inflow. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] This utility model provides a sewage pretreatment device for water supply and drainage pipelines, including a base plate 1:

[0026] The top of the base plate 1 is provided with a barrier mechanism 2 for filtering out large-volume impurities, the back of the base plate 1 is provided with a mounting mechanism 3 for locking the barrier mechanism 2, and the top surface of the barrier mechanism 2 is provided with a pushing mechanism 4 for cleaning the barrier mechanism 2.

[0027] The barrier mechanism 2 includes a support assembly disposed on the top of the base plate 1 and a filter assembly connected to the support assembly;

[0028] The mounting mechanism 3 includes a connecting component disposed at one end of the support component and a clamping component adapted to the connecting component;

[0029] The pushing mechanism 4 includes a pushing component disposed on top of the support component and a cleaning component connected to the pushing component.

[0030] Preferred:

[0031] like Figure 2 As shown, the support assembly includes an outer frame 21 fixedly installed on the top of the base plate 1, and an inner frame 22 fixedly installed on the top of the base plate 1, which serves to enclose the water flow to prevent leakage and to temporarily accumulate filtered impurities.

[0032] Preferred:

[0033] like Figure 2As shown, the filter assembly includes a fixed frame 23 placed on the top surface of the inner frame 22 and a grid body 24 fixed to the inner side wall of the fixed frame 23. A vertical plate 25 is fixedly installed at one end of the fixed frame 23. A through hole 26 is opened on one side of the vertical plate 25 and the corresponding side of the inner frame 22. The fixed frame 23 is used to assist water intake and support the grid body 24. The grid body 24 filters and blocks large-volume impurities, while the vertical plate 25 is used to limit the position and assist the installation operation.

[0034] further:

[0035] like Figure 2 As shown, the connecting assembly includes a bracket 31 fixedly installed at one end of the outer frame 21, and a screw 32 is threadedly connected through the center of one side of the bracket 31 to facilitate the extension and pushing of the screw.

[0036] in:

[0037] like Figure 3 As shown, the clamping assembly includes a push plate 33 rotatably connected to one end of the screw 32. A locking block 35 is fixedly installed on one side of the push plate 33, and a crossbar 34 is fixedly installed on the other side of the push plate 33. It can be pushed and inserted to lock the vertical plate 25 and the fixed frame 23 fixed thereto.

[0038] It is worth noting that:

[0039] like Figure 4 As shown, the pushing component includes a mounting plate 41 fixedly installed on the top surface of the fixed frame 23. An electric push rod 42 is fixedly installed on the inclined surface of the top of the mounting plate 41, which can push and adjust the position of the cleaning plate 43.

[0040] at last:

[0041] like Figure 4 As shown, the cleaning assembly includes a cleaning plate 43 fixedly installed at the output end of the electric push rod 42. Two telescopic rods 44, which are fixedly installed through the mounting plate 41, are fixedly installed at both ends of one side of the cleaning plate 43, which can ensure stable pushing and push large-volume impurities away from the grid body 24.

[0042] First, the grille body 24 needs to be installed and placed on the inner frame 22. Then, rotate the screw 32 and push the vertical plate 25 to move horizontally inside the bracket 31. To ensure the stability of the horizontal movement, the horizontal bar 34 will move laterally. The horizontal bar 34 and the bracket 31 are connected by a through sliding connection until the vertical plate 25 pushes the locking block 35 to move and passes through the vertical plate 25 and the inner frame 22 in sequence through the through hole 26, thereby realizing the insertion and clamping operation. At this time, the installation is completed. When disassembly is required, the installation method is reversed as described above.

[0043] During pretreatment, water from the water supply and drainage pipes will directly enter the interior of the outer frame 21 and pass through the grille body 24 into the inner frame 22. Then, it will be discharged downward through the corresponding drainage holes on the top of the bottom plate 1 for subsequent treatment. When passing through the grille body 24, the grille body 24 will block large-volume impurities and other floating objects, thereby achieving pretreatment filtration. Long-term blocking will cause a lot of impurities to adhere to the surface of the grille body 24, which is prone to clogging and reduces the water intake. At this time, it should be cleaned by the pushing mechanism 4.

[0044] During cleaning, the electric push rod 42 is directly activated to push the cleaning plate 43 to tilt downward. Since the cleaning surface of the cleaning plate 43 has cleaning teeth, it can push the impurities attached to the surface of the screen body 24 to the bottom, thereby avoiding blockage and ensuring water intake. It is only necessary to remove the cleaned impurities periodically. In addition, to ensure the stability of the cleaning plate 43 during movement, the telescopic rod 44 will be stretched when it is pushed. The two sets of telescopic rods 44 can improve the stable support force to ensure smooth operation.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
