Description

Technical Field

[0001] This invention relates to the field of rainwater and sewage separation system technology, and specifically to a rainwater and sewage separation system for municipal underground pipeline projects. Background Technology

[0002] Rainwater and sewage separation is a drainage system that separates rainwater and sewage, each using its own pipeline for discharge or subsequent treatment. Rainwater is discharged directly into rivers through the rainwater pipe network, while sewage is collected through the sewage pipe network and sent to sewage treatment plants for treatment, thus preventing sewage from directly entering rivers and causing pollution. However, existing rainwater and sewage separation systems have certain inconveniences in use.

[0003] Chinese invention patent application number CN202010132609.X discloses a rainwater and sewage separation system for municipal engineering. This invention separates rainwater and domestic sewage through a rainwater and sewage separation device. Rainwater is collected through a water guide channel and flows into the rainwater chamber from the filter plate, while domestic sewage enters the sewage chamber through the sewage inlet pipe. The collected rainwater is discharged through the rainwater drain pipe, and the collected sewage is discharged through the sewage drain pipe. This rainwater and sewage separation system is relatively convenient. However, this rainwater and sewage separation system is not convenient for separating debris in rainwater and is not convenient for cleaning and collection. In addition, it is not convenient for cleaning mud and dirt contained in sewage, which can easily cause pipe blockage. Furthermore, the rainwater and sewage separation system is not convenient for disassembly and assembly. Due to the special working environment, the pressure resistance and corrosion resistance of the rainwater and sewage separation system are generally poor. Therefore, we propose a rainwater and sewage separation system for municipal underground pipeline engineering. Summary of the Invention

This provides a limiting and fixing effect for the connector rod, facilitating quick disassembly and assembly of the diversion tank. The protective rubber pads and blocks at the bottom of the fixed base plate provide pressure resistance for the diversion tank, and the rubber material of the protective rubber pads and blocks has good corrosion resistance. The second drive motor can drive the sedimentation base to rotate during use, allowing the cleaning scraper to adhere to the surface of the sedimentation base and clean and remove the sludge settled on the surface of the sedimentation base. The removed sludge will flow into the sludge discharge valve pipe for discharge. Attached Figure Description

A lever 23 is welded to the outer wall of the shaft 21. A connecting rod 25 is fixedly connected between the shaft 21 and the separation screen cylinder 24. When the separation pipe 3 is in use, the shaft 21 can be rotated through the bearing seat 22. During the process of rainwater and sewage entering the separation pipe 3, the lever 23 on the shaft 21 will be impacted, which will cause the shaft 21 to rotate.

Then, the limiting pin 13 is inserted into the insertion groove 30 through the pin hole 31 and rotated so that it is connected and fixed to the screw hole 34 on the plug rod 32 through the thread 33. This can limit and fix the plug rod 32, which facilitates quick disassembly and assembly of the diversion tank 1. In addition, the protective rubber pad 14 and rubber block 29 at the bottom of the fixed bottom plate 12 can provide pressure resistance for the diversion tank 1, and the rubber material of the protective rubber pad 14 and rubber block 29 has good corrosion resistance.

[0024] In another embodiment of the present invention, an equipment electrical box 2 is bolted to the top outer surface of the diversion tank 1. The equipment electrical box 2 mainly serves to supply power during use. The outer wall of the diversion tank 1 is detachably connected to a sewage discharge valve pipe 5, a sludge discharge valve pipe 6, and a rainwater discharge valve pipe 7. The sewage discharge valve pipe 5 is located above the sludge discharge valve pipe 6, and the sludge discharge valve pipe 6 is located on one side of the rainwater discharge valve pipe 7. The sewage discharge valve pipe 5 facilitates the discharge of sewage, the sludge discharge valve pipe 6 facilitates the discharge of sludge from the sewage, and the rainwater discharge valve pipe 7 facilitates the discharge of rainwater.

[0025] In one embodiment of the present invention, the separating mesh cylinder 24 extends into the interior of the diversion tank 1, and the separating mesh cylinder 24 and the collection tank 4 are interconnected. The number of the baffles 23 is 5 to 8. When in use, the separating mesh cylinder 24 is mainly used to separate debris from rainwater and sewage.

[0026] In another embodiment of the present invention, the spiral rod 26 penetrates the collection tank 4 and is located at the center of the collection tank 4. The first drive motor 10 is electrically connected to the equipment electrical box 2. When in use, the first drive motor 10 can drive the spiral rod 26 to rotate in both directions, which can cause the spiral rod 26 to drive the movable slider 27 to move up and down.

[0027] In another embodiment of the present invention, the protective pad 14 and the rubber block 29 are integrally formed. The protective pad 14 and the rubber block 29 are made of rubber. The insertion groove 30 and the pin hole 31 are through structures. The limiting pin 13 is connected to the screw hole 34 through the thread 33.

[0028] In one embodiment of the present invention, the sedimentation base 18 has a conical structure, the cleaning scraper 20 is in contact with the surface of the sedimentation base 18, the sedimentation base 18 is installed at the output shaft end of the second drive motor 17, the second drive motor 17 is electrically connected to the equipment electrical box 2, the discharge hole 19 has an inclined structure, the second drive motor 17 can drive the sedimentation base 18 to rotate during use, so that the cleaning scraper 20 can be in contact with the surface of the sedimentation base 18 to clean and remove the mud and dirt deposited on the surface of the sedimentation base 18, and the removed mud and dirt will flow into the mud and dirt discharge valve pipe 6 for discharge.

[0029] It should be noted that this invention is a rainwater and sewage separation system for municipal underground pipeline projects. Before installing the diversion tank 1, the fixed base plate 12 can be fixed at the installation location. Then, the fixed top plate 11 at the bottom of the diversion tank 1 can be inserted into the insertion groove 30 in the fixed base plate 12 via the insertion rod 32. Then, the limiting pin 13 is inserted into the insertion groove 30 through the pin hole 31, and the limiting pin 13 is rotated so that it is connected and fixed to the screw hole 34 on the insertion rod 32 through the thread 33. This can limit and fix the insertion rod 32, which facilitates quick disassembly and assembly of the diversion tank 1. In addition, the protective rubber pad 14 and rubber block 29 at the bottom of the fixed base plate 12 can provide pressure resistance for the diversion tank 1. Furthermore, the rubber material of the protective pads 14 and 29 has good corrosion resistance. During use, the rainwater and sewage inlet pipe 8 can be connected to the municipal underground pipeline. During rainwater and sewage discharge, the rainwater and sewage will enter the separation pipe 3 through the rainwater and sewage inlet pipe 8. At this time, the rainwater and sewage will impact the deflector 23 on the shaft 21, causing the shaft 21 to rotate through the bearing seat 22. The shaft 21, through the connecting rod 25, will drive the separation screen cylinder 24 to rotate. The separation screen cylinder 24 can filter impurities in the rainwater and sewage, and the impurities will rotate and slide down into the collection tank 4 for collection. After collecting the filtered impurities, the collection tank 4 stores them on the carrier plate 28. When it is necessary to clean the impurities, the sealing cover 9 can be opened first, and then... Restart the first drive motor 10, which provides the screw rod 26 to drive the moving slider 27 upward, allowing the carrier plate 28 to push out the collected debris for easy cleaning. The filtered rainwater and sewage will enter one side of the separator plate 16. Due to the large flow rate of the rainwater and sewage, the water level in the diversion tank 1 will gradually rise, and the mud and sludge contained in the rainwater and sewage will settle and adhere to the sedimentation base 18. At this time, the relatively clean rainwater above will be discharged into the other side of the separator plate 16 through the discharge hole 19 and discharged through the rainwater discharge valve pipe 7. The relatively mixed sewage at the bottom of one side of the separator plate 16 can be discharged through the sewage discharge valve pipe 5. When it is necessary to clean the settled mud and sludge, the second drive motor can be started. Motor 17, the second drive motor 17 can drive the sedimentation base 18 to rotate, so that the cleaning scraper 20 can be attached to the surface of the sedimentation base 18 to clean and remove the mud and dirt settled on the surface of the sedimentation base 18. The cleaning scraper 20 is fixed next to the port of the mud and dirt discharge valve pipe 6. When the mud and dirt are scraped off and accumulated, they will slide into the mud and dirt discharge valve pipe 6 for discharge. In normal weather without rain, the discharged sewage will be separated into the same way as the debris, and then the sewage will fall into one side of the partition plate 16. Since the daily sewage flow is small and can be continuously discharged through the sewage discharge valve pipe 5, the sewage cannot enter the other side of the partition plate 16. In rainy weather with a large rain and sewage flow, it can better separate rain and sewage.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
