Description

Technical Field

[0001] This application relates to the field of municipal wastewater treatment technology, and in particular to a municipal wastewater treatment device with good filtration effect. Background Technology

[0002] Sewage includes domestic sewage, industrial wastewater, and runoff within urban areas. It is generally collected by urban pipe networks and treated at urban wastewater treatment plants before being discharged into water bodies. Municipal wastewater treatment is the process of treating urban domestic sewage and some industrial wastewater to meet discharge or reuse standards.

[0003] Chinese utility model patent CN222389600U discloses a multi-stage filtration municipal wastewater treatment device, comprising a wastewater treatment channel body and a first plate and a second plate. The first plate is installed above the wastewater treatment channel body, and the second plate is located on the left side of the first plate. The municipal wastewater treatment device provided by this utility model features a two-stage filtration system. The first stage of filtration involves the coordinated operation of the first and second plates. The second plate uses a driving component to move the first plate to one side, enabling automated cleaning during filtration without requiring the pipes to be sealed. Furthermore, multiple secondary filter plates inside the wastewater treatment channel body also perform secondary filtration. This multi-stage filtration system ensures more thorough initial filtration of municipal wastewater, reduces the time interval for cleaning the filter screens, and thus improves the practicality of the equipment.

[0004] In actual use, since the sewage pipe is located above the main body of the sewage treatment channel, the second plate uses a drive component to drive the first plate to move to one side. When cleaning the filter screen, only the second plate can be cleaned. The first plate is located on the main body of the channel, and the garbage remaining on the first plate is not easy to clean. It can only be cleaned by staff. When the staff cleans it, there is a risk of garbage falling into the main body of the channel. Utility Model Content

[0005] To facilitate cleaning of the filter plates, this application provides a municipal wastewater treatment device with good filtration effect.

[0006] This application provides a municipal wastewater treatment device with good filtration effect, which adopts the following technical solution:

[0007] A municipal sewage treatment device with good filtration effect includes a channel body, a first filter plate and a second filter plate. Both the first filter plate and the second filter plate are provided with filter screens. The first filter plate and the second filter plate are arranged vertically. A driving mechanism is provided on the channel body. The driving mechanism drives the first filter plate to slide. The sliding of the first filter plate drives the second filter plate to slide. Both the first filter plate and the second filter plate are slidably disposed on the channel body. The sliding direction of the first filter plate and the second filter plate is perpendicular to the length direction of the channel body.

[0008] By adopting the above technical solution, when sewage is discharged from the main body of the channel, garbage remains on the first or second filter plate. The driving mechanism drives the first filter plate to slide, which in turn drives the second filter plate to slide. When the first filter plate slides out of the main body of the channel, the garbage on the first filter plate can be cleaned. At the same time, the second filter plate replaces the first filter plate to perform sewage filtration. After a suitable time, the driving mechanism drives the first filter plate to slide, so that the first filter plate is back above the main body of the channel to perform sewage filtration. At this time, the second filter plate is outside the main body of the channel, and the second filter plate can be cleaned. The filter plate is easy to clean.

[0009] Optionally, both the first filter plate and the second filter plate have grooves, and the filter screen is disposed at the bottom of the groove.

[0010] The above technical solution is mainly used to retain the waste filtered after sewage discharge, so that the waste is not easily washed into the main body of the channel during subsequent sewage discharge.

[0011] Optionally, the main body of the channel is provided with a splash guard plate, through which a sewage pipe passes. The sewage pipe is used to discharge sewage, and the splash guard plate is located above the first filter plate or the second filter plate.

[0012] By adopting the above technical solution, the splash guard prevents sewage from splashing out during sewage discharge, and all sewage can be filtered through the first or second filter plate, thereby improving the sewage treatment effect.

[0013] Optionally, the driving mechanism includes a motor and a threaded rod. The motor is located on one side of the channel body, and the threaded rod is coaxially located at the output end of the motor. A sliding block is threadedly connected to the threaded rod, and the sliding block is located on the first filter plate. The motor drives the threaded rod to rotate and causes the sliding block to slide back and forth. The sliding block causes the first filter plate to slide.

[0014] By adopting the above technical solution, the sliding block is driven to slide by the motor and the threaded rod. The sliding block drives the first filter plate to slide back and forth. When the first filter plate filters sewage, the second filter plate cleans up the garbage, or when the second filter plate filters sewage, the first filter plate cleans up the garbage. The forward and reverse rotation of the motor enables the cleaning of garbage between the first filter plate and the second filter plate.

[0015] Optionally, the first filter plate and the second filter plate are rotatably connected by a hinge. The sliding block is disposed at the end edge of the first filter plate near the second filter plate. The sliding block is provided with a rotating shaft, and the first filter plate is provided with a rotating groove for the rotating shaft to rotate.

[0016] By adopting the above technical solution, when the second filter plate is filtering, the first filter plate and the second filter plate are rotatably connected by a hinge, and at the same time, the rotating shaft is rotatably connected to the first filter plate. The first filter plate is tilted and the garbage is emptied by the hinge and the rotating shaft. After the garbage is emptied, the first filter plate is pulled and slid by the motor.

[0017] Optionally, storage boxes are provided on both sides of the main channel.

[0018] By adopting the above technical solution, the storage box is used to store the garbage dumped from the first filter plate and the second filter plate.

[0019] Optionally, inclined blocks are provided on both sides of the channel body, which support the first or second filter plate when it is tilted.

[0020] By adopting the above technical solution, the tilting block is used to support the tilt of the first filter plate or the second filter plate, preventing the hinge from being damaged due to excessive tilt angle of the first filter plate or the second filter plate.

[0021] Optionally, a secondary filter plate is provided on the main body of the channel.

[0022] By adopting the above technical solution, the secondary filter plate provides the effect of sewage filtration and prevents residual waste.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Regardless of which filter plate is filtering wastewater, the other filter plate can be cleaned of debris, making the filter plates easy to clean;

[0025] 2. The groove retains the waste filtered after sewage discharge;

[0026] 3. The first filter plate is tilted and the garbage is emptied by using the hinge and pivot. Attached Figure Description

Filter screens 41 are fixed on both the first filter plate 2 and the second filter plate 3, and the first filter plate 2 and the second filter plate 3 are arranged vertically. A secondary filter plate 9 is fixed on the channel body 1. A driving mechanism 5 is provided on the channel body 1, which drives the first filter plate 2 to slide. The sliding of the first filter plate 2 causes the second filter plate 3 to slide. Both the first filter plate 2 and the second filter plate 3 are slidably connected to the channel body 1, and the sliding direction of the first filter plate 2 and the second filter plate 3 is perpendicular to the length direction of the channel body 1.

[0034] Reference Figure 1 , Figure 2 Both the first filter plate 2 and the second filter plate 3 have grooves 42, and the filter screen 41 is fixed to the bottom of the groove 42. A splash guard 43 is fixed on the main body of the channel 1, and the sewage pipe passes through the splash guard 43. The sewage pipe is used to discharge sewage, and the splash guard 43 is located above the first filter plate 2 or the second filter plate 3.

[0035] Reference Figure 1 , Figure 2 , Figure 3The drive mechanism 5 includes a motor 51 and a threaded rod 52. The motor 51 is fixed to one side of the channel body 1, and the threaded rod 52 is coaxially fixed to the output end of the motor 51. A sliding block 6 is threadedly connected to the threaded rod 52. The sliding block 6 is fixed to the first filter plate 2. The motor 51 drives the threaded rod 52 to rotate and drives the sliding block 6 to slide back and forth. The sliding block 6 drives the first filter plate 2 to slide.

[0036] Reference Figure 2 , Figure 3 , Figure 4 The first filter plate 2 and the second filter plate 3 are rotatably connected by a hinge. The sliding block 6 is fixed to the end edge of the first filter plate 2 near the second filter plate 3. A rotating shaft 71 is fixed on the sliding block 6. A rotating groove 72 is provided on the first filter plate 2 for the rotating shaft 71 to rotate and connect.

[0037] Reference Figure 1 , Figure 2 Storage boxes 73 are fixed on both sides of the main channel 1. Inclined blocks 8 are fixed on both side walls of the main channel 1, which support the first filter plate 2 or the second filter plate 3 when tilted. Water outlet pipes 74 are fixed on the opposite side walls of the splash guard plate 43. The water outlet pipes 74 spray water onto the first filter plate 2 and the second filter plate 3.

[0038] The implementation principle of a municipal sewage treatment device with good filtration effect according to an embodiment of this application is as follows: When sewage is discharged from the main body of the channel 1, garbage remains on the first filter plate 2 or the second filter plate 3. The motor 51 drives the sliding block 6 to slide, and the sliding block 6 drives the first filter plate 2 to slide. The first filter plate 2 drives the second filter plate 3 to slide. When the first filter plate 2 slides out of the main body of the channel 1, the first filter plate 2 is tilted by the rotating shaft 71 and the hinge to dump the garbage. The water outlet pipe 74 washes the garbage remaining on the first filter plate 2. When the first filter plate 2 is on the main body of the channel for filtration, the second filter plate 3 tilts to dump the garbage, and the water outlet pipe 74 washes the garbage remaining on the second filter plate 3. Moreover, due to the splash guard 43, the garbage is not easy to stay in the main body of the channel 1, and the sewage treatment effect is better. The first filter plate 2 is driven to slide back and forth by the forward and reverse rotation of the motor 51. Both the first filter plate 2 and the second filter plate 3 can be cleaned. The time for the staff to clean the filter screen 41 is greatly reduced, and the filter plate is easy to clean.
