Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an environmentally friendly wastewater filtration device. Background Technology

[0002] Wastewater refers to water discharged from domestic and industrial sources that has been polluted to a certain extent and has lost its original function. It is mainly water used for domestic purposes, containing a relatively high amount of organic matter, and is relatively easy to treat. Wastewater needs to be treated by a wastewater filtration device before discharge. After prolonged use, impurities accumulate on the surface of the filter screen. To ensure the normal operation of the wastewater filtration device, these impurities need to be removed. At the same time, using a filter screen to filter wastewater plays an environmental protection role.

[0003] Existing environmentally friendly wastewater filtration and purification devices are prone to clogging if there are too many impurities in the wastewater, which affects the filtration efficiency. The impurities need to be cleaned again, or the filter screen can be tilted to allow the impurities to accumulate at the bottom and make the filtration at the top smoother. However, if the screen is not cleaned in time, it will also cause clogging. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an environmentally friendly wastewater filtration device that, through a rotating scooping device, a flocculation sedimentation device, and a squeezing filtration device, facilitates continuous filtration operation and is less prone to clogging.

[0005] This invention also provides an environmentally friendly wastewater filtration device, comprising: a filter box, an internal rotary scooping device, a flocculation sedimentation device and a rotary separation device at the bottom of the filter box, an internal transfer device within the flocculation sedimentation device, a surface treatment device on the surface of the flocculation sedimentation device, and a squeeze filtration device on the side surface of the filter box. The rotary scooping device, flocculation sedimentation device, and squeeze filtration device facilitate continuous filtration and reduce the likelihood of clogging.

[0006] According to the present invention, an environmentally friendly wastewater filtration device includes a filter box comprising a box body, a funnel-shaped inlet fixedly connected to the top of the box body, and an opening communicating with a squeezing filtration device on the side of the box body. A retaining sleeve is provided on the inner surface of the inlet. These components facilitate the fixing of wastewater discharge pipes, thereby preventing wastewater leakage.

[0007] According to the present invention, an environmentally friendly wastewater filtration device includes a rotating scooping device comprising a rotating shaft, both ends of which are fixedly connected to a housing. A filter screen is fixedly connected to the side surface of the rotating shaft. A filter chamber is fixedly located inside the filter housing, the bottom of which communicates with an opening. A scraper is movably connected to the side wall of the filter chamber via a spring. A filtrate hole is fixedly connected to the side surface of the filter chamber and communicates with the filter housing. Through these components, wastewater can be initially filtered by multiple rotating filter screens, removing solid particles and impurities.

[0008] According to the present invention, an environmentally friendly wastewater filtration device includes a dosing device and a flocculation inlet. The dosing device is disposed on the side surface of the filter box, and the flocculation inlet is located at the bottom of the filter box. A transmission pipe is disposed at the bottom of the flocculation inlet, and a discharge pipe is fixedly connected to the transmission pipe via a pump body. The outlet of the discharge pipe is located above the filter chamber. Through these components, wastewater can be flocculated, thereby allowing it to settle and be discharged.

[0009] According to the present invention, an environmentally friendly wastewater filtration device includes a dosing device comprising a rotating cylinder driven by a drive motor. The rotating cylinder contains a chemical agent, and its side surface has holes. A stirring rod is fixedly connected to the side surface of the rotating cylinder, and a dosing port is fixedly connected to the top of the rotating cylinder. The drive motor is fixedly connected to the bottom of a filter box, with the dosing port located at the top of the filter box, and the rotating cylinder located inside the filter box. These components allow for simultaneous discharge and stirring of the flocculant, resulting in faster flocculation and reduced mixing time.

[0010] According to the present invention, an environmentally friendly wastewater filtration device includes a transfer pump. An inlet pipe is fixedly connected to the input end of the transfer pump, with the inlet of the inlet pipe located at the flocculation port. An outlet pipe is fixedly connected to the input end of the transfer pump, and the outlet pipe is located inside the rotary separation device. Through these components, flocculated wastewater can be discharged into the rotary separation device.

[0011] According to the present invention, an environmentally friendly wastewater filtration device includes a surface treatment device comprising an electric telescopic rod, the output end of which is fixedly connected to a slider. An arc-shaped suction pipe is disposed inside the slider. The arc-shaped suction pipe is connected to a storage tank via a suction pump, and the storage tank is located outside the filter box. These components allow for the removal of floating debris from the surface after flocculation.

[0012] According to the present invention, an environmentally friendly wastewater filtration device includes a rotary separation device comprising a drainage chamber with a drain outlet on its side surface. A centrifugal chamber is rotatably connected inside the drainage chamber, and a connecting rod is fixedly connected to the center of the centrifugal chamber. A centrifugal motor is fixedly connected to one end of the connecting rod and is fixedly connected to the upper surface of the filter box. Through these components, incoming wastewater can be centrifugally filtered, and the internally treated wastewater can be discharged.

[0013] According to the present invention, an environmentally friendly wastewater filtration device includes a squeezing chamber, a cylinder at the bottom of the squeezing chamber, a pressure plate fixedly connected to the output end of the cylinder, filter holes inside the pressure plate, a door movably connected to the upper end of the squeezing chamber, and a filter box connected to the bottom end of the squeezing chamber. Through these components, sediment can be effectively pressurized and filtered, thereby discharging it.

[0014] An environmentally friendly wastewater filtration method, employing the environmentally friendly wastewater filtration device described above, includes the following steps:

[0015] S1. Pre-filtration: The generated wastewater enters the device through the feed inlet at the top of the filter box. Large particles and impurities are filtered by the rotating filter screen. During the rotation, it does not affect the subsequent entry of wastewater. The filtered material is transferred to the inside of the filter chamber by a scraper after the filter screen has rotated.

[0016] S2. Flocculation Filtration: The wastewater that has passed the initial filtration falls into the filter box. The dosing device rotates, while the flocculant inside is thrown out. At the same time, the internal part is stirred by the stirring rod. When the dosing ends, the internal stirring stops simultaneously.

[0017] S3. Flocculation treatment: The stirring of the wastewater is slowly stopped, and the flocculated wastewater impurities are transferred to the filter chamber through the discharge pipe.

[0018] S4. Compression process: The items inside the filter chamber enter the compression chamber through the opening. The cylinder drives the pressure plate to move, compressing and filtering the impurities inside. After the door is opened, the cylinder continues to move, expelling the impurities.

[0019] S5. Surface treatment: After the compression treatment is completed, the surface is positioned on the water surface by lifting the arc-shaped water suction pipe, and the floating objects on the surface are sucked into the storage box through the arc-shaped water suction pipe.

[0020] S6. Final treatment: Water is added to the centrifuge chamber by a transfer pump. The wastewater is filtered through the rotating centrifuge chamber to obtain the final treated water. The treated water is discharged through the drain outlet.

[0021] Beneficial effects:

[0022] This invention, through a rotating scooping device, a flocculation sedimentation device, and a squeezing filtration device, facilitates continuous water filtration operations and is less prone to clogging.

[0023] This invention uses a centrifugal and stirring-based dosing method to disperse the drug while simultaneously re-dispersing it, which reduces the time required for drug addition and stirring, resulting in faster flocculation. Attached Figure Description
