Description

Technical Field

[0001] The utility model relates to the technical field of municipal rainwater and sewage diversion, in particular to a municipal rainwater and sewage diversion device. Background Art

[0002] Rainwater is a natural resource. In order to make better use of rainwater resources, it is usually necessary to collect and treat rainwater. Since the cleanliness of rainwater is often greater than that of urban sewage, in order to reduce the pressure of water treatment, rainwater and sewage need to be discharged separately. Rainwater and sewage diversion is a drainage mechanism, which refers to the sewage discharge method of discharging rainwater and sewage separately, transporting them through their own pipes for discharge or subsequent treatment, so that water of different cleanliness can be treated separately to reduce the pressure of water treatment. However, when the rainwater discharge volume is small, it usually causes the dust on the ground to flow, and the cleanliness is low, so it needs to be discharged into the sewage pipe. When the rainwater discharge volume is large, the cleanliness is high and it can be discharged into the rainwater pipe.

[0003] Patent CN220394779U proposes a municipal pipeline rainwater and sewage diversion device, which can monitor the internal pressure of the municipal pipeline rainwater and sewage diversion device in real time through a pressure detection component. When the rainwater discharge volume is small, it usually causes the dust on the ground to flow, the cleanliness is low, the internal pressure of the municipal pipeline rainwater and sewage diversion device is small, and the sewage is discharged from the sewage pipe. When the rainwater discharge volume is large, the cleanliness is high, and the internal pressure of the municipal pipeline rainwater and sewage diversion device is large. At this time, it will switch to the rainwater pipe, and the rainwater will be discharged from the rainwater pipe.

[0004] In the above scheme, the pressure sensor monitors the pressure inside the device, thereby switching the discharge direction of the pipe. However, in this technology, when there is a lot of rain, it will drive mud and garbage in the environment into the device. If the pipe is directly converted to discharge it into the lake, it is easy to pollute the environment. The process of separating rainwater and sewage requires a certain amount of sedimentation time. In the existing technology, it is impossible to provide a stable sedimentation space under the condition of continuous discharge, which can easily lead to poor sedimentation effect, insufficient separation of rainwater and sewage, and other problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a municipal rainwater and sewage diversion device to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. Three groups of diversion layers are arranged in the outer box for alternating use. Impurities in rainwater and sewage are filtered through filter plates and then sent to the first group of diversion layers. After the diversion layers are filled with liquid, the suspended balls block the entry pipe to maintain a stable sedimentation environment. Rainwater and sewage are sent out separately from the discharge port and the delivery trough after sedimentation and stratification. In this process, the mixed liquid of rainwater and sewage is sent to the next group of diversion layers, which will not cause blockage of the drainage system. It can also improve the effect of sewage and rainwater separation and collection, avoid environmental pollution and also reduce the pressure of sewage treatment plants.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a municipal rainwater and sewage diversion device, including an outer box, a diversion box is fixed inside the outer box, and three groups of diversion layers are arranged inside the diversion box, an inclined surface is arranged on the top of the diversion layer, and an inlet pipe is opened at the center of the inclined surface of the diversion layer, delivery grooves are opened on the inner walls on both sides of the bottom of the diversion layer, and baffles are inserted inside the delivery grooves, a delivery outlet is opened on the middle inner wall of the diversion layer, and a plug is inserted inside the delivery outlet, a suspended ball is arranged inside the diversion layer, and the suspended ball can be inserted and blocked at the bottom of the inlet pipe, a first discharge pipe is opened at a position corresponding to the three groups of diversion layers on one side of the outer wall of the outer box, and the first discharge pipe is connected to the delivery outlet, a second discharge pipe is opened on the outer wall of the outer box at the bottom of the first discharge pipe, and the second discharge pipe is connected to the delivery groove, and a water inlet is opened on the top of one end of the outer box.

[0007] Furthermore, a filter plate is fixed inside the outer box between the water inlet and the diversion box, and a box door is installed on one side of the outer box located on the filter plate through a hinge.

[0008] Furthermore, slide rails are fixed to the inner walls on both sides of the diversion layer, and slide racks are fixed to both sides of the bottom of the suspension ball, and the slide racks slide along the slide rails.

[0009] Furthermore, a telescopic plate is fixed on the surface of the baffle and the plug column in the same vertical line in the diversion layer, and a clamping plate is fixed on the top of the telescopic plate, and the clamping plate can be pressed and contacted with the bottom of the suspension ball.

[0010] Furthermore, electric push rods are fixed on both sides of the outer box, and the extended ends of the electric push rods penetrate into the diversion layer and are fixed to the telescopic plate.

[0011] Furthermore, a conical surface is fixed on the bottom of the diversion layer, and the bottom of the baffle slides along the conical surface.

[0012] Furthermore, a guide seat is fixed to the top entrance end of the inlet pipe, and a push rod is slidably inserted inside the guide seat, a fence frame is fixed to the top of the push rod, and the fence frame can be slidably inserted into the filter groove of the filter plate, the push rod is located between the guide seat and the fence frame and is sleeved with a spring, and the bottom of the push rod is in extrusion contact with the suspended ball.

[0014] 1. The utility model filters larger impurities through the filter plate, and the box door is conveniently opened manually to clean the impurities remaining on the filter plate.

[0015] 2. In the utility model, as the water level rises, the slides on both sides slide along the slide rails until the suspension ball is inserted into the tube and squeezes the bottom of the top rod. The top rod drives the fence frame to move up along the guide seat and insert into the filter groove of the filter plate, so that sewage and rainwater will no longer flow into the diversion layer, thereby guiding them to flow into the next diversion layer.

[0016] 3. The utility model uses an electric push rod to push the two sets of telescopic plates to move quickly toward the middle. At this time, the two clamping plates are combined at the bottom of the suspension ball to keep the suspension ball from falling and continue to block the inlet pipe.

[0017] 4. Compared with the prior art, the utility model sets three groups of diversion layers in the outer box for alternating use. Impurities in rainwater and sewage are filtered through filter plates and then sent into the first group of diversion layers. After the diversion layers are filled with liquid, the suspended balls block the entry pipe to maintain a stable sedimentation environment. After the rainwater and sewage are separated by sedimentation and stratification, they are sent out separately from the discharge port and the delivery trough. In this process, the mixed liquid of rainwater and sewage is sent into the next group of diversion layers, which will not cause blockage of the drainage system, and can also improve the effect of separation, treatment and collection of sewage and rainwater, avoid environmental pollution and also reduce the pressure of sewage treatment plants.

A second discharge pipe 14 is provided on the outer wall of the outer box 1 at the bottom of the first discharge pipe 13, and the second discharge pipe 14 is connected to the delivery trough 32. A water inlet 11 is provided on the top of one end of the outer box 1. When the device is used, sewage and rainwater are sent into the outer box 1 through the water inlet pipe, and enter the three-group diversion layer 31 in sequence after being filtered through the filter plate 2. After sedimentation and stratification in the diversion layer 31, the rainwater and sewage are sent out through the first discharge pipe 13 and the second discharge pipe 14.

[0025] In this embodiment, a filter plate 2 is fixed inside the outer box 1 between the water inlet 11 and the diversion box 3, and a box door 12 is installed on one side of the outer box 1 on the filter plate 2 through a hinge. Larger impurities are filtered through the filter plate 2, and the box door 12 is convenient for manual opening to clean the impurities remaining on the filter plate 2.

[0026] In this embodiment, the inner walls of both sides of the diversion layer 31 are fixed with slide rails 310, the two sides of the bottom of the suspension ball 312 are fixed with slide racks 311, and the slide racks 311 slide along the slide rails 310, the top inlet end of the inlet pipe 34 is fixed with a guide seat 315, and the guide seat 315 is slidably inserted with a top rod 316, the top of the top rod 316 is fixed with a fence frame 317, and the fence frame 317 can be slidably inserted into the filter tank of the filter plate 2, and the top rod 316 is located between the guide seat 315 and the fence frame 317.

The top rod 316 drives the fence frame 317 to move up along the guide seat 315 and insert into the filter groove of the filter plate 2, so that sewage and rainwater will no longer flow into the diversion layer 31, thereby guiding it to flow into the next diversion layer 31.

[0027] In this embodiment, a telescopic plate 36 is fixed on the surface of the baffle 38 and the plug post 37 in the same vertical line in the diversion layer 31, and a clamping plate 313 is fixed on the top of the telescopic plate 36, and the clamping plate 313 can be squeezed and contacted with the bottom of the suspension ball 312, and electric push rods 35 are fixed on both sides of the outer box 1, and the extended end of the electric push rod 35 penetrates into the diversion layer 31 and is fixed to the telescopic plate 36, and a conical surface 39 is fixed at the bottom of the diversion layer 31, and the bottom of the baffle 38 slides along the conical surface 39.

The sewage on the lower layer is transported through the cone surface 39 and delivered to the sewage treatment plant through the second discharge pipe 14. After delivery, the plug 37 and the baffle 38 are reset, and the suspension ball 312 returns to the bottom of the diversion layer 31 (the water level inside the diversion layer 31 can be detected by a conventional liquid level sensor to open or close the electric push rod 35).

[0028] When the device is used, sewage and rainwater are sent into the outer box 1 through the water inlet pipe, filtered through the filter plate 2, and then enter the three groups of diversion layers 31 in sequence. After the suspension ball 312 blocks the inlet pipe 34, the plug column 37 blocks the discharge port, and the baffle 38 blocks the delivery slot 32.
