Problems solved by technology

[0003] Because solid garbage has been soaked in sewage for a long time, some materials with good water absorption (such as absorbent cotton and other textile materials) have certain adhesion after absorbing a large amount of water. After being filtered by the filter, they will adhere to the filter. , it is difficult to fall off, resulting in a great reduction in the filtration efficiency of the filter screen, and it is necessary to manually clean the filter screen regularly
It consumes manpower and material resources, and at the same time, manual cleaning is prone to untimely situations, resulting in low overall efficiency of sewage treatment

Embodiment 1

[0023] refer to Figure 1-2 , a high-efficiency sewage treatment filter equipment, including equipment base 1, the upper end of the equipment base 1 is provided with a water inlet 2, the side wall of the equipment base 1 is provided with a circular groove 3 communicating with the water inlet 2, the circular groove 3 The inner coaxial seal is rotatably connected with a turntable 4 , the side wall of the turntable 4 is provided with a plurality of through holes 41 of different sizes, and the side wall of the turntable 4 is coaxially fixedly connected with a water wheel 5 . A water outlet 7 communicating with the inside of the circular groove 3 is opened on the side wall of the equipment base 1 .

[0024] It should be noted that the blades of the water wheel 5 and the through hole 41 are arranged in a misaligned position, so as to prevent the blades of the water wheel 5 from blocking the through hole 41 and obstructing the flow of sewage. The calibers of the water inlet 2 and th...

Embodiment 2

[0032] refer to image 3 , and the difference from the first embodiment is that the buoyancy scraper 8 is made of magnetic material, the filter screen 9 is made of a hollow structure, and the filter screen 9 is embedded with a plurality of iron springs 91 .

[0033] In this embodiment, since the buoyant scraper 8 is made of magnets and the springs 91 are made of iron, the buoyant scraper 8 will be close to each spring 91 in the filter screen 9 during the process of floating up and down.

[0034] Whenever the magnetic buoyancy scraper 8 approaches a certain spring 91, the spring 91 will shrink along the direction of the buoyancy scraper 8, and when the buoyancy scraper 8 leaves, the spring 91 will elongate and recover under the action of the elastic force. In this way, during the up-and-down floating process of the buoyancy scraper 8, the springs 91 in the filter screen 9 are stretched one by one, and the outer wall of the filter screen 9 is continuously shaken, which can promo...

Embodiment 3

[0036] refer to Figure 4-5 , and the difference from the second embodiment is that the side wall of the device base 1 is provided with an air inlet 6 communicating with the water outlet 7, and the air inlet 6 communicates with the inside of the filter screen 9. Such as Figure 4 As shown, the air inlet 6 communicates with the water outlet 7 , and the air outlet end of the air inlet 6 is arranged inside the hollow filter screen 9 .

[0037] In this embodiment, when the sewage flows in the water outlet 7, because the water flow velocity in the water outlet 7 is fast and the pressure is low, the air flow velocity in the air inlet 6 connected with the water outlet 7 is slow and the pressure is strong, so that the water flow in the air inlet A pressure difference is generated in the hole 6, and the air is continuously sucked in from the air inlet hole 6, and the air flowing in from the air inlet hole 6 will enter the filter screen 9 and be discharged from the filter hole of the f...

Abstract

The invention discloses efficient filtering equipment for sewage treatment. The equipment comprises an equipment base body, a water inlet is formed in the upper end of the equipment base body; a circular groove communicated with the water inlet is formed in the side wall of the equipment base body; a rotary disc is coaxially, hermetically and rotatably connected into the circular groove; a plurality of through holes with different sizes are formed in the side wall of the rotary disc, a water wheel is coaxially and fixedly connected to the side wall of the rotary disc, a water outlet communicating with the interior of the circular groove is formed in the side wall of the equipment base body, a filter screen is embedded in the water outlet, and a buoyancy scraper matched with the filter screen is slidably connected into the water outlet. Sewage flows out through the through holes with different sizes, and the liquid level in the water outlet can continuously fluctuate up and down, so that the buoyancy scraper in the water outlet moves up and down along with the liquid level, garbage and impurities adhered to the filter screen can be scraped into a storage tank under the filter screenin time, good permeability of the filter screen is kept, and the sewage treatment efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of equipment related to sewage treatment, in particular to a high-efficiency filter equipment for sewage treatment. Background technique [0002] In the initial stage of sewage treatment, it is often necessary to separate the solid waste in the sewage to facilitate subsequent treatment of the sewage. [0003] Because solid garbage has been soaked in sewage for a long time, some materials with good water absorption (such as absorbent cotton and other textile materials) have a certain degree of adhesion after absorbing a large amount of water. , It is difficult to fall off, which greatly reduces the filtration efficiency of the filter screen, and the filter screen needs to be manually cleaned regularly. It consumes manpower and material resources, and at the same time, manual cleaning is prone to untimely situations, resulting in low overall efficiency of sewage treatment. Accordingly, this application docum...
