Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, specifically a wastewater filtration device for water environment pollution prevention and control. Background Technology

[0002] Wastewater filtration is an important wastewater treatment method that aims to remove impurities, pollutants, and harmful substances from wastewater through physical, chemical, or biological means, thereby purifying the wastewater to meet specific usage or discharge standards. The purpose of wastewater filtration is to remove solid impurities: wastewater typically contains solid impurities of various sizes, such as silt, leaves, twigs, plastic fragments, and paper. If these solid impurities are not removed, they will affect the operation of subsequent wastewater treatment processes, clog pipes and equipment, and reduce the quality of the final effluent. Filtration intercepts these large solid particles outside the filter medium, thus initially purifying the wastewater. For example, in the pretreatment stage of urban wastewater treatment plants, large floating objects and solid impurities are first removed using coarse filtration equipment such as screens to prevent them from entering subsequent treatment units.

[0003] The existing technical solution has the following drawbacks: when filtering solid impurities in water, the solid impurities will clog the surface of the filter screen, which will cause the speed of sewage passing through the area to be greatly reduced, resulting in poor filtration efficiency and reduced filtration effect. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a sewage filtration device for water pollution prevention and control, which has the advantage of being easy to clean. It solves the problem that when filtering solid impurities in water, solid impurities will clog the surface of the filter screen, resulting in a significant reduction in the speed of sewage passing through this area, thus leading to poor sewage filtration efficiency and reduced sewage filtration effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater filtration device for water environment pollution prevention and control, comprising a coarse filter pipe, an inlet pipe connected to the top of the coarse filter pipe, a fine filter pipe connected to the bottom of the coarse filter pipe, a purification pipe connected to the bottom of the fine filter pipe, an outlet pipe connected to the bottom of the purification pipe, a drive mechanism provided inside the coarse filter pipe, and a recycling mechanism provided on the right side of the coarse filter pipe.

[0006] In a preferred embodiment of this utility model, the driving mechanism includes a motor frame, the bottom of which is fixedly connected to the top of the coarse filter tube. A drive motor is fixedly connected inside the motor frame, and a drive shaft is fixedly connected to the output end of the drive motor. A connecting frame is fixedly connected to the bottom of the drive shaft, and a filter screen is fixedly connected to the top of the connecting frame. A drive wheel is fixedly sleeved on the surface of the drive shaft, and a belt is rotatably sleeved on the surface of the drive wheel. A driven wheel is rotatably sleeved on the right side of the belt.

[0007] In a preferred embodiment of this invention, the recycling mechanism includes a housing, the outer side of which is fixedly connected to the inside of a coarse filter tube, a rotating rod rotatably connected to the inside of the housing, the top of which is fixedly connected to the inside of a driven wheel, a storage box communicating with the right side of the housing, and a collection frame slidably connected to the inside of the storage box.

[0008] As a preferred embodiment of this invention, a brush plate is fixedly connected inside the coarse filter tube, and the brush plate is used in conjunction with the filter screen.

[0009] As a preferred embodiment of this invention, a recycling tube is fixedly connected to the bottom of the storage box, and the output end of the recycling tube is used in conjunction with a coarse filter tube.

[0010] As a preferred embodiment of this invention, an observation window is fixedly connected to the rear side of the storage box, and the observation window is located to the right of the drive motor.

[0011] As a preferred embodiment of this invention, the surface of the rotating rod is provided with a circular hole, which is located at the top of the connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model involves wastewater flowing into the coarse filter tube through the inlet pipe. As the wastewater passes through the filter screen, solid impurities are left on its surface. The wastewater then flows into the fine filter tube and the purification tube. After filtration, the water is discharged through the outlet pipe. Starting the drive motor causes the drive shaft, connecting frame, filter screen, drive wheel, belt, driven wheel, and rotating rod to rotate. The filter screen rotates, collecting the solid impurities through the housing. The rotating rod then transports the solid impurities upwards to the storage box. Pulling the collection frame cleans the solid impurities inside. This solves the problem that when filtering water, solid impurities clog the filter screen surface, significantly reducing the speed of wastewater passing through this area and resulting in poor filtration efficiency. It also offers the advantage of easy cleaning.

[0014] 2. This utility model, by setting a drive mechanism, can be used in conjunction with a recycling mechanism. By starting the drive motor, the output end of the drive motor drives the drive shaft, connecting frame, filter screen, drive wheel, belt, driven wheel, and rotating rod to rotate. The filter screen drives the solid impurities to rotate, and the solid impurities are collected through the housing, thus improving the collection effect of solid impurities.
