Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage pipe network anti-blocking, in particular to an anti-blocking device for rural domestic sewage pipe network. Background Technique
[0002] The discharge points of rural domestic sewage are numerous and widespread, which are the main reasons for the blackening and stinking of water bodies in rural areas and the decline of the quality of the human settlement environment. Some rural concentrated residential areas are characterized by a large amount of domestic sewage generation, many sewage branch pipe networks, and small pipe diameters. After the construction of a centralized sewage collection and treatment system, due to problems such as the water use habits of villagers, the phenomenon of directly pouring domestic garbage and kitchen waste (leftovers, leftovers, grease, etc.) into the sewage pipe or inspection well has led to the blockage of rural sewage pipe networks becoming the primary problem encountered in the operation and maintenance process of the sewage system.
[0003] There are no effective preventive measures for the blockage of sewage pipe networks in rural areas, only treatment measures after blockage. Due to the weak economic foundation in rural areas and the small diameter of sewage pipes, it is not possible to adopt special equipment or manual underwater dredging. Hydraulic dredging and mechanical dredging are mainly used. However, due to reasons such as living habits, the sediments in rural sewage pipe networks are mostly large-sized substances such as leftovers and leftovers, with a relatively large specific gravity. The effect of hydraulic flushing is not ideal, and the water resources in rural areas are more inconvenient to obtain than in cities; mechanical dredging generally needs to be carried out in cooperation with equipment such as winches. In the case of serious blockage, the manual dragging is greatly restricted. In some rural areas, new pipes are dug and built again after blockage, resulting in a waste of manpower, material resources and financial resources; in some areas, it is left unattended, and only the inspection well is properly cleaned after it is full of blockage, resulting in problems such as frequent sewage overflowing and stinking from the inspection well.

[0027] Reference Figures 1-4As shown in the figure, an embodiment of the present utility model is as follows:
[0028] An anti-blocking device for rural domestic sewage pipe networks includes a first grille frame 1 on the slag inlet side and a second grille frame 2 on the slag blocking side. The lower end of the first grille frame 1 is hinged to the lower end of the second grille frame 2. Pulling ropes 3 are provided at the upper ends of both the first grille frame 1 and the second grille frame 2. When the pulling rope 3 on the first grille frame 1 is lifted, the first grille frame 1 flips towards the second grille frame 2 and encloses a grille basket that is vertically through. A slag storage mesh bag 4 is provided at the lower end of the grille basket.
[0029] As Figure 4 shown, the present utility model is installed in a pipe network inspection well. Specifically, the second grille frame 2 is placed at the position of the well outlet inside the well, the first grille frame 1 faces the slag inlet side, and the pulling rope of the first grille frame 1 is lowered to make the first grille frame 1 in a horizontal state so that larger particle wastes in the sewage can enter the second grille frame 2. The larger particle wastes are intercepted by the blockage of the second grille frame, and the sewage and small particle wastes then smoothly pass through the second grille frame 2 and flow to the downstream pipeline, effectively preventing the problem of pipe network blockage. During operation and maintenance, the anti-blocking device can be regularly cleaned. Specifically, a suspension ring 5 is provided at the other end of the pulling rope to be suspended and fixed on the anti-falling net hook at the wellhead. Open the inspection well, remove the anti-falling net at the wellhead, and first lift the pulling rope 3 on the first grille frame 1, then remove the suspension ring 5. First, lift the pulling rope 3 on the first grille frame 1 to make the first grille frame 1 flip towards the second grille frame 2, changing its state from horizontal to vertical. During this process, part of the wastes staying on the first grille frame 1 are pushed into the vertically through grille basket. Then, lift all the pulling ropes 3 together, and the anti-blocking device moves vertically and smoothly out of the inspection well. Large particle wastes such as garbage and suspended matters enter the slag storage mesh bag 4 by gravity. Move the anti-blocking device outside the well and clean the intercepted objects in the slag storage mesh bag, and clean the grille slag adhered to the grille. Then, slowly place the cleaned anti-blocking device in the bottom outlet chute of the well. After placing it in the designated position, first loosen the pulling rope 3 of the second grille frame 2, and then loosen the pulling rope 1 of the first grille frame 1 to make the first grille frame in a horizontal state. Hang the suspension ring 5 on the anti-falling net hook, restore the installation of the anti-falling net and close the manhole cover. The operation is simple and convenient, which can also reduce the manual work intensity, with low operation and maintenance difficulty. It forms a decentralized multi-stage solid waste collection and treatment at the front end where the sewage flows through, and can subcontract the operation and maintenance cleaning responsibility to individual villagers, reducing the operation and maintenance cost.
[0030] Specifically, both the first grille frame 1 and the second grille frame 2 include an outer frame 121. A number of slag blocking grilles 122 are spaced inside the outer frame. A pulling ring 6 for fixing the pulling rope 3 is provided at the upper end of the outer frame 121. The slag storage mesh bag 4 is provided at the lower end of the second grille frame 2.
[0031] In this embodiment, the grille basket formed by the first grille frame 1 and the second grille frame 2 is of a rectangular structure, that is: the second grille 2 is a grille frame formed by winding three sides in the rectangular structure, and the first grille frame 1 is the remaining single-sided grille frame. The first grille frame 1 and the second grille frame 2 are only hinged at the lower end through a hinge. In a specific embodiment, the specific material of the outer frame 121 is welded by stainless steel square tubes, the slag blocking grille 122 is made of stainless steel round steel, the spacing of the slag blocking grille 122 is 15-25 mm, the slag storage mesh bag 4 is made of high-strength polyethylene material, the mesh size is: 10 mm * 10 mm, and the depth of the bag is ≥ 150 mm. It can be understood that the first grille frame and the second grille frame 2 are not limited to a rectangular structure, and can also be other fence-shaped structures with a storage space, as long as it is ensured that the first grille frame 1 is a flat plane grille so as not to block the solid waste in the sewage from entering the storage space.
[0032] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
