Description

Technical Field

[0001] This utility model relates to the field of rainwater and sewage separation technology, specifically to a rainwater and sewage separation device for municipal engineering. Background Technology

[0002] Separating rainwater and sewage is a drainage system that separates rainwater and sewage, each transported through its own pipeline for discharge or subsequent treatment. Rainwater can be discharged directly into rivers through a rainwater pipe network, while sewage needs to be collected through a sewage pipe network and sent to a sewage treatment plant for treatment. Only after the water quality meets the corresponding national or local standards can it be discharged into rivers, thus preventing river pollution.

[0003] Application number CN202420635623.5 discloses a rainwater and sewage separation device for municipal engineering. An automatic separation blocker is installed inside the rainwater and sewage separation box and above the rainwater separation pipe inlet. During the rainy season, it achieves rainwater separation, diverting large amounts of water resources during the middle and later stages of rainfall into the municipal rainwater pipe network, improving rainwater utilization and preventing large amounts of rainwater from flowing into sewage treatment plants and increasing sewage treatment costs. However, the above design still has shortcomings. An inlet pipe is installed at the top of the rainwater and sewage separation box. This inlet pipe has a simple structure and can only accept water from a single source, limiting its application.

[0004] Therefore, we propose a rainwater and sewage separation device for municipal engineering. Utility Model Content

[0005] The main objective of this invention is to provide a municipal engineering rainwater and sewage separation device. By setting up two sets of relatively independent filter chambers and filter mechanisms, it achieves multi-channel water inlet and multi-stage filtration. The two sets of water inlet pipes can be connected to rainwater or sewage from different areas respectively. Compared with traditional rainwater and sewage separation devices with a single water inlet pipe, this greatly improves the applicability and scope of use of the device. At the same time, the filter mechanism composed of filter screen and filter cover fully filters the liquid before it enters the rainwater and sewage separation box, effectively reducing the entry of solid impurities into the rainwater and sewage separation box, reducing the risk of blockage inside the rainwater and sewage separation box, and improving the working efficiency and service life of the rainwater and sewage separation box. This effectively solves the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A municipal engineering rainwater and sewage separation device includes a rainwater and sewage separation box, a conveying pipe, and a pretreatment box.

A first base and a second base are respectively connected to the lower parts of both sides of the pretreatment box. A connecting pipe is fixedly inserted into the center of the bottom end of the pretreatment box. The pretreatment box has a cavity inside that communicates with the connecting pipe. The inner wall of the cavity has an installation groove for installing the separation box. The separation box is snapped into the pretreatment box.

[0008] The diversion box contains two sets of relatively independent filter chambers. Each filter chamber contains a filter mechanism, which includes a filter screen and a filter cover.

The filter screen is inclined and there are two sets of filter screens facing each other. The top of the pretreatment box and the diversion box are fastened together with a sealing cover. Two sets of relatively parallel water inlet pipes are vertically inserted into the upper surface of the sealing cover and are connected to the filter chamber.

[0009] By adopting the above technical solution

[0010] Specifically, the pretreatment box is a vertically arranged rectangular structure, and the bottom end of the connecting pipe is fixedly connected to and communicates with the top end of the conveying pipe.

[0011] Specifically, the bottom end of the filter cover passes through the mounting hole and is located below the diversion box, the upper outer part of the filter cover is snapped into the bottom end of the diversion box, and two sets of filter covers are arranged in parallel.

[0012] Specifically, the filter screen is located above the filter cover, and the filter screen is obliquely engaged with the inner wall of the filter chamber.

[0013] Specifically, the first base and the second base are arranged opposite to each other, the conveying pipe is located between the first base and the second base, and the upper part of the first base and the second base near the conveying pipe is provided with a positioning groove that matches the lower part of the pretreatment box. The first base and the second base are fixedly connected by a connecting rod.

[0014] Specifically, the bottom ends of the first base and the second base are fixedly connected to the top of the rainwater and sewage diversion box by the first bolt, and the upper part of the first base and the second base on the side away from the conveying pipe is fixedly connected to the bottom of the pretreatment box by the second bolt.

The upper surface of the sealing cover 7 is vertically inserted with two sets of relatively parallel water inlet pipes 8, which are connected to the filter chamber 12.

[0024] In use, by setting up two relatively independent filter chambers and filter mechanisms, multi-channel water inlet and multi-stage filtration are achieved; the two sets of water inlet pipes can be connected to rainwater or sewage from different areas respectively. Compared with the traditional rainwater and sewage diversion device with a single water inlet pipe, the applicability and scope of use of the device are greatly improved; at the same time, the filter mechanism composed of filter screen and filter cover fully filters the liquid before it enters the rainwater and sewage diversion box, effectively reducing the entry of solid impurities into the rainwater and sewage diversion box, reducing the risk of blockage inside the rainwater and sewage diversion box, and improving the working efficiency and service life of the rainwater and sewage diversion box.

[0025] This utility model also includes a pretreatment box 3 being a vertically arranged rectangular structure, and the bottom end of the connecting pipe 11 being fixedly connected and communicating with the top end of the conveying pipe 2.

[0026] The present invention also includes that the bottom end of the filter cover 6 passes through the mounting hole 15 and is located below the diversion box 5, the upper outer side of the filter cover 6 is snapped with the bottom end of the diversion box 5, and two sets of filter covers 6 are arranged in parallel relative to each other.

[0027] The present invention also includes that the filter screen plate 14 is located above the filter cover 6, and the filter screen plate 14 is inclinedly engaged with the inner wall of the filter cavity 12.

[0028] The present invention also includes that the first base 18 and the second base 19 are arranged opposite to each other, the conveying pipe 2 is located between the first base 18 and the second base 19, and the upper part of the first base 18 and the second base 19 near the conveying pipe 2 is provided with a positioning groove 16 that is adapted to the lower part of the pretreatment box 3. The first base 18 and the second base 19 are fixedly connected by a connecting rod 17.

[0029] The present invention also includes that the bottom ends of the first base 18 and the second base 19 are fixedly connected to the top of the rainwater and sewage diversion box 1 by the first bolt 20, and the upper part of the first base 18 and the second base 19 on the side away from the conveying pipe 2 are fixedly connected to the bottom of the pretreatment box 3 by the second bolt.

[0030] In use, the first base 18 and the second base 19 are first fixed to the top of the rainwater and sewage diversion box 1 by the first bolt 20.

[0032] When rainwater or sewage flows in from the inlet pipe 8, it first passes through the inclined filter screen 14. The filter screen 14 can intercept larger solid impurities. Due to its inclined design, the impurities will slide down the inclined surface, making it easy to clean. The liquid that has undergone preliminary filtration continues to flow downward and enters the filter cover 6 for secondary filtration. The filter cover 6 further filters out smaller impurities. The filtered liquid enters the rainwater and sewage diversion box 1 through the connecting pipe 11 and the conveying pipe 2, where it undergoes subsequent rainwater and sewage diversion treatment.
