Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage pipe networks, in particular to a municipal engineering sewage pipe network purification device. Background Art
[0002] Sewage pipes typically require pretreatment before entering a sewage treatment plant. The purpose of pretreatment is to remove large debris, perform preliminary sterilization, and remove some suspended solids through sedimentation, thereby reducing the burden on subsequent sewage treatment processes and improving overall treatment efficiency.
[0003] Existing pretreatment methods typically involve setting up a purification well at the confluence of sewage pipes, and installing a filter inside the well to intercept debris in the sewage. However, as sewage flow increases and debris accumulates, a large amount of debris tends to accumulate on the filter, gradually reducing its filtration efficiency. In severe cases, this can lead to pipe blockage, which not only affects the normal discharge and purification of sewage but can also cause overflows or damage to the pipe network due to increased pressure. Therefore, the filtered debris needs to be regularly processed. Traditional filtration processes are not effective in treating filtered waste, and each cleaning process requires a significant amount of manpower and material resources, which is time-consuming and labor-intensive.
[0004] Based on this, it is necessary to study a municipal engineering sewage pipe network purification device. Utility Model Content

DETAILED DESCRIPTION
[0028] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:
[0029] This embodiment aims to provide a municipal engineering sewage pipe network purification device, which is mainly used to pre-treat sewage in the municipal engineering sewage pipe network, and addresses the problem that debris intercepted by existing purification devices easily clogs the filter and is difficult to clean.
[0030] A municipal engineering sewage pipe network purification device, such as Figure 1 , comprising a purification well 1, a first filter plate 2, a water inlet pipe 3, a drain pipe 4, a sewage pipe 5, and a timing valve 6. A water inlet 101 and a drain outlet 102 are provided on the sidewall of the purification well 1, with the water inlet 101 located above the drain outlet 102. A sewage outlet 103 is provided at the bottom of the purification well 1. The first filter plate 2 is fixedly installed horizontally in the purification well 1 and located below the drain outlet 102, serving to separate the purification well 1 into two upper and lower areas connected only by the first filter plate 2. The first filter plate 2 is provided with a vertical through-port.
[0031] The water inlet pipe 3 passes through the water inlet 101 and the outlet in sequence and is connected to the area below the first filter plate 2 in the purification well 1, and is used to input sewage into the purification well 1. The size and shape of the water inlet pipe 3 correspond to and are adapted to the outlet.
[0032] The drain pipe 4 is connected to the drain outlet 102, and the sewage pipe 5 is connected to the sewage outlet 103, which is mainly used to output pre-treated sewage; the timing valve 6 is set in the sewage outlet 103 and periodically opens and closes the sewage outlet 103. The timing valve 6 opens and closes periodically, and an electronic timing solenoid valve can be used. The delay period that can meet the actual needs is set by designing test results. The timing valve 6 opens to discharge sewage after a delay period accumulates at the bottom of the purification well 1. The sewage pipe is connected to a sewage treatment equipment that specializes in treating high-impurity waste to centrally treat the waste.
[0033] When this embodiment is in use, the water inlet pipe 3 discharges sewage into the area below the first filter plate 2 in the purification well 1 and gradually accumulates. When the water level rises to the first filter plate 2, the sewage passes through the first filter plate 2 from bottom to top for filtration and overflows from the drain outlet 102 after filtration, thereby preventing debris from accumulating above the first filter plate 2; the debris gradually settles at the bottom of the purification well 1 and is regularly discharged through the sewage outlet 103 and the timing valve 6 at the bottom of the purification well 1, thereby avoiding manual cleaning of the garbage, effectively solving the problem that debris intercepted by the existing purification device easily clogs the filter screen and is inconvenient to clean, thereby reducing the maintenance cost of the sewage pipe network purification well 1.
[0034] Furthermore, considering that a certain amount of sewage is stored in the purification well 1 for a long time, it is possible to perform purification operations such as sterilization and sedimentation on the stored sewage. Figure 2 and Figure 3 A vertical barrel 7 is provided in the middle of the first filter plate 2. The barrel 7 is located below the first filter plate 2. The barrel 7 has a material cavity 701 with an upper opening. The side wall of the barrel 7 is provided with several filter holes 702 connected to the material cavity 701. The material cavity 701 is mainly used to accommodate the purification material rod 8.
[0035] like Figure 4 A limiting column 9 is provided at the upper end of the purification material rod 8. The purification material rod 8 can be an ultraviolet lamp rod for sterilizing sewage. In this case, the limiting column 9 can be connected to the purification material rod 8 by a threaded connection, and the limiting column 9 is mainly used as a lamp holder; the purification material rod 8 can also be a flocculant rod for precipitating sewage. In this case, the limiting column 9 can cover the purification material rod 8 by providing a net bag; the purification material rod 8 can also be an activated carbon rod for deodorizing sewage. In this case, the limiting column 9 can be connected to the purification material rod 8 by a snap connection; whether it is a threaded connection, a net bag connection or a snap connection, all adopt existing conventional technical means, which will not be repeated here, and is intended to fix the purification material rod 8 and the limiting column 9.
[0036] The upper end surface of the barrel 7 is fixedly connected to a limit seat 11, which contains a limit cavity 1104 with upper and lower openings. The upper opening of the limit cavity 1104 matches the shape of the limit block, and the lower opening of the limit cavity 1104 communicates with the material chamber 701. The diameters of the upper and lower openings are both smaller than the inner diameter of the limit cavity 1104. A limit block 10 is fixed to the side wall of the limit post 9. The upper end surface of the limit seat 11 is provided with a notch 1103 that matches the shape of the limit block 10. The limit block 10 can pass through the notch 1103 and enter the limit cavity 1104. It is then rotated to be fixed in the limit cavity 1104, which is used to detachably connect the limit post 9 to the limit seat 11, thereby retaining the purification material rod 8 in the material chamber 701.
[0037] Furthermore, in order to facilitate the processing of the limiting seat 11, as Figure 4 The limiting seat 11 is horizontally divided from the middle into a seat body 1101 and a ring cover 1102 connected by screws; the lower opening of the limiting cavity 1104 is opened at the bottom of the seat body 1101; the upper opening of the limiting cavity 1104 and the notch 1103 are opened on the ring cover 1102.
[0038] Furthermore, in order to facilitate the replacement of the purification material rod 8, the upper end face of the limiting column 9 is fixedly connected to an upwardly extending extension rod 12, and a handle 13 is fixed to the top of the extension rod 12. By holding the handle 13 and rotating it, the purification material rod 8 and the limiting column 9 can be quickly removed from the limiting seat 11.
[0039] Furthermore, a second filter plate 14 is provided on the upper end surface of the first filter plate 2 , and the inner diameter of the filter holes 702 of the second filter plate 14 is smaller than the inner diameter of the filter holes 702 of the first filter plate 2 , thereby forming a two-stage filtration and improving the filtration accuracy.
