Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to an ecological filter tank with a large-area composite filler structure. Background Art

[0002] In modern industrial production and production life, a large amount of sewage of various types is generated, which contains a large amount of organic matter and harmful substances. Industrial wastewater contains a large amount of grease and organic matter, which usually needs to be treated before discharge. Untreated sewage will cause water hypoxia, and even produce odor and death of aquatic plants. It will also cause serious harm to the environment and human health. After multi-stage decontamination treatment, sewage can be used for normal industrial water or domestic water. Existing sewage treatment mostly adopts sewage treatment tanks to treat sewage in biological or chemical forms. Among them, the composite ecological filter can use a biological layer with fillers with physical properties and an aeration device to treat sewage according to the characteristics of the sewage to be treated. At present, the composite ecological filter mostly uses a microbial layer to biologically treat sewage. When the filter is not in use or suspended, the sludge and microbial layer in the sewage will be deposited to the bottom of the filter. When the filter is started again, the aeration mechanism is a certain distance away from the bottom of the pool. The microbial community and sludge accumulated at the bottom are not easy to diffuse back into the water body. In addition, when the wastewater is treated, it is affected by the aeration mechanism. A large amount of oil-containing foam often floats on the surface of the water body, blocking the contact between the water body and oxygen, reducing the efficiency of sewage treatment, and affecting the sewage treatment effect.

[0003] For example, a composite ecological filter for rural domestic sewage treatment with publication number CN117142659A includes a filter body, a No. 1 partition is fixedly installed on the inner wall of the filter body, a No. 1 water outlet is opened on the outer wall of the No. 1 partition, and a baffle is installed on the inner wall of the filter body, and there are several baffles. The layered biochemical pool is composed of a No. 1 sliding block 502 and a No. 2 sliding block 503, and the top of the vetiver 106 planted and the bottom composite microbial layer 202 is formed. The aeration pipe 201 is activated to allow the composite microbial layer 202 to spread and react better. The above-mentioned filter only uses the aeration pipe to diffuse the microbial community deposited at the bottom, and cannot disturb the water body at the bottom. It takes a long time of aeration to achieve the effect of uniform diffusion, and it cannot process the grease foam on the surface of the water body. Therefore, this application designs an ecological filter with a large-area composite filler structure that can diffuse the sludge and microorganisms at the bottom of the pool by stirring and vibrating, and process the foam on the surface of the water body by rotating.

DETAILED DESCRIPTION

[0030] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0031] like Figures 1 to 13As shown, the present application proposes an ecological filter tank with a large-area composite filler structure, including a tank body 1, a composite filler layer 2, an aeration mechanism 3, a transmission mechanism 4, and an adsorption mechanism 5 for adsorbing grease foam on the water surface; the composite filler layer 2 is arranged in the middle of the tank body 1, one end of the adsorption mechanism 5 is slidably connected to the upper part of the inner wall of the tank body 1, and the other end of the adsorption mechanism 5 is fixedly connected to the upper end of the transmission mechanism 4, the aeration mechanism 3 is arranged at the bottom of the tank body 1, and the lower part of the transmission mechanism 4 is fixedly connected to the aeration mechanism 3; an air blocking component 6 is arranged in the aeration mechanism 3, and the air blocking component 6 blocks the airflow and sprays it in a concentrated manner to aerate the aeration mechanism 3 with pressure; the aeration mechanism 3 rotates under the influence of the recoil force, and then the adsorption mechanism 5 is rotated through the transmission mechanism 4 to adsorb grease foam on the water surface. The tank body 1 is provided with a water inlet and a water outlet, and a microbial layer is arranged at the lower part of the tank body 1, and the composite filler layer 2 is composed of multiple layers of different fillers. The sewage to be treated enters the filter tank through the water inlet for treatment. The composite filler layer 2 composed of a variety of composite materials can filter and chemically react with different types of sewage, and the sewage is biologically treated through the microbial layer at the bottom of the tank body 1. When the filter tank is started, the gas enters the water body to be treated through the aeration mechanism 3, and the air flow in the aeration mechanism 3 is blocked by the air blocking component 6, so that the air pressure in the aeration mechanism 3 rises, and finally the gas is excited into the water body, so that the aeration mechanism 3 rotates under the action of the recoil force, and then the sludge and microbial layer accumulated at the bottom of the tank body 1 are scraped into the coverage range of the aeration mechanism 3, and the vibration generated by the pressure jet is used to spread the sludge and microbial community to the entire water body faster. At the same time, through the reverse transmission of the transmission mechanism 4, the rotation of the aeration mechanism 3 drives the adsorption mechanism 5 on the surface of the water body to rotate, so as to adsorb the grease foam on the surface of the water body to prevent it from hindering the contact between the water body and the air, and at the same time reduce the process of treating the grease foam alone.

[0032] As another example, Figures 1 to 4 As shown, the aeration mechanism 3 includes a main aeration pipe 31, an aeration plate 32, a through pipe 33, and a plurality of ring aeration pipes 34; the main aeration pipe 31 passes through the side wall of the tank body 1 and is rotatably connected to the middle of the ring aeration pipe 34, and a support frame 311 is fixedly provided on the main aeration pipe 31, and the other end of the support frame 311 is rotatably connected to the transmission mechanism 4. The plurality of ring aeration pipes 34 are interconnected, and the aeration plate 32 is connected to the ring aeration plate 32 through the through pipe 33. The aeration plate 32 is evenly distributed along the circumference of the ring aeration pipe 34, and the aeration plate 32 is tilted, and its tilt direction is rotatably arranged along the circumference of the ring aeration plate 32. The gas is transported by the main aeration pipe 31, enters the ring aeration pipe 34 from the middle position of the bottom of the tank body 1, and is transported to the ring aeration pipes 34 of each level, and finally enters the aeration plate 32 through the through pipe 33 for pressure aeration.

[0033] See also Figure 2 and Figure 3The lower part of the annular aeration tube 34 is provided with a spoiler scraper 341 and a supporting cylinder 342. The spoiler scraper 341 is provided in a plurality of groups, and the plurality of spoiler scrapers 341 are evenly arranged along the circumference of the annular aeration tube 34. The supporting cylinder 342 is provided in an array, and the supporting cylinder 342 is symmetrically arranged along the circumference of the annular aeration tube 34. The supporting cylinder 342 is used to assist in supporting the annular aeration tube 34. When the annular aeration tube 34 rotates, the supporting cylinder 342 further rolls on the bottom of the pool. The bottom of the spoiler ring plate is a soft gasket, and when the annular aeration tube 34 rotates, the sludge and microorganisms at the bottom of the pool body 1 are scraped up through the soft gasket.

[0034] As another example, Figures 5 to 9 As shown, a gas storage layer 321 is provided in the aeration plate 32, and the gas storage layer 321 is connected to the through pipe 33. Aeration holes 322 are provided on the surface of the aeration plate 32, and the aeration holes 322 are connected to the gas storage layer 321. The aeration holes 322 extend to both sides of the gas storage layer 321, and a trigger pin 3222 is fixed on the step 3221. The gas in the annular aeration pipe 34 flows into the gas storage layer 321 and is discharged through the aeration holes 322 connected to the gas storage layer 321.

[0035] See also Figure 7 and Figure 8 The air blocking component 6 includes a rotating shaft 61, a trigger rod 62 and an array of arc plates 63. The arc plates 63 are arranged in a circle. The middle of the arc surface of the arc plate 63 is fixedly connected to the rotating shaft 61, and the lower end of the trigger rod 62 is fixedly connected to the upper side of the rotating shaft 61. The straight edge end of the arc plate 63 is made of rubber material. When the array of arc plates 63 is closed, there is no gap, which can further limit the flow of air and prevent the air from entering the aeration hole 322. A torsion spring 325 is arranged in the rotating shaft 61, and the torsion spring 325 drives the rotation to rotate downward.

[0036] See also Figures 6 to 9A pressure plate 323 is provided at the connection point between the aeration hole 322 and the gas storage layer 321. The side of the pressure plate 323 is slidably connected to the inner wall of the aeration hole 322. The pressure plate 323 is a hollow structure. The arc plate 63 and the pressure plate 323 are rotatably connected at the middle of the pressure plate 323 through the rotating shaft 61. A limiting sealing ring plate 324 is provided at the lower part of the pressure plate 323. An array of springs 325 are fixedly provided around the upper part of the pressure plate 323. The other end of the spring 325 is fixedly connected to the steps 3221 extending to both sides of the aeration hole 322. As the airflow continues to enter the air storage chamber, the air pressure in the air storage chamber increases, and the pressure plate 323 drives the arc plate 63 to move upward along the inner wall of the aeration hole 322, thereby compressing the spring 325. When the trigger pin 3222 fits the trigger rod 62 and presses the trigger rod 62 downward, the rotating shaft 61 is driven to rotate, so that the arc plate 63 is opened, the airflow is stimulated, and enters the water body through the aeration hole 322 to generate vibration and recoil force, and the recoil force drives the annular aeration tube 34 to rotate, and the sludge and microorganisms are further diffused to other parts of the water body through vibration. After the airflow is stimulated, the air pressure decreases, and the pressure plate 323 is driven down by the spring 325, and the trigger pin 3222 is separated from the trigger rod 62. The rotating shaft 61 is reversed by the torsion spring 325, closing the arc plate 63. The limiting sealing ring plate 324 limits the arc plate 63 to prevent it from opening downward, and at the same time seals the position of the rotating shaft 61 to prevent gas from overflowing from the rotating shaft 61. As the pressure height increases, the pressure plate 323 rises again for cyclic aeration.

[0037] As another example, Figure 2 , Figures 10 to 13As shown, the transmission mechanism 4 includes a forward drive rod 41, a reverse drive rod 42, a first connecting rod 43, a second connecting rod 44 and a reverse assembly 45; the forward drive rod 41 is fixedly connected to the inner wall of the middle part of the ring aeration pipe 34 through the first connecting rod 43, and the reverse assembly 45 is fixedly connected to the inner wall of the main aeration pipe 31 through the second connecting rod 44. The upper part of the forward drive rod 41 extends into the reverse assembly 45, and the lower end of the reverse drive rod 42 extends into the reverse assembly 45. The upper end of the reverse drive rod 42 passes through the main aeration pipe 31 and extends to the surface of the water body. The upper end side wall of the reverse drive rod 42 is plugged into the adsorption mechanism 5; the reverse drive rod 42 is rotatably connected to the support frame 311 to vertically support the reverse drive rod 42 when it rotates. The reversing assembly 45 includes a protective cover 451, a driving bevel gear 452, a driven bevel gear 453 and a bevel gear 454. The driving bevel gear 452, the driven bevel gear 453 and the bevel gear 454 are all rotatably connected to the protective cover 451. The outer side of the protective cover 451 is fixedly connected to the second connecting rod 44. The upper part of the forward driving rod 41 passes through the protective cover 451 and is plugged into the driving bevel gear 452. The lower part of the reversing driving rod 42 passes through the protective cover 451 and is plugged into the driven bevel gear 453. The driving bevel gear 452 and the driven bevel gear 453 are meshed with the bevel gear 454. When the annular aeration tube 34 rotates, the forward driving rod 41 inside it is driven to rotate, which in turn drives the driving bevel gear 452 to rotate, so that the bevel gear 454 meshing with the driving bevel gear 452 rotates. The rotation of the bevel gear 454 drives the driven bevel gear 453 to rotate in the opposite direction relative to the driving bevel gear 452, and finally drives the reverse driving rod 42 to rotate in the opposite direction. The reverse driving rod 42 extends to the surface of the water body, driving the adsorption mechanism 5 to rotate.

[0038] See also Fig. 9The adsorption mechanism 5 includes a connecting column 51, a water-blocking curved panel 52 and an annular adsorption plate 53 for adsorbing grease foam; the water-blocking curved panel 52 is fixedly connected to the annular adsorption plate 53, one end of the annular adsorption plate 53 is plugged into the connecting column 51, and the other side of the annular adsorption plate 53 is slidably connected to the upper part of the inner wall of the pool body 1, and the end of the connecting column 51 away from the annular adsorption plate 53 is plugged into the reversing drive rod 42, and an oleophobic round nail 521 is provided on the surface of the water-blocking curved panel 52. The surface of the oleophobic round nail 521 is coated with an oleophobic coating, which can puncture the foam on the surface of the water body to prevent it from staying on the surface of the annular adsorption plate 53 due to surface tension. At the same time, the surface of the water body is located at a position lower than the upper end of the water-blocking curved panel 52, and the annular adsorption plate 53 is completely in the water body. As the adsorption mechanism 5 rotates, the water-blocking curved panel 52 contacts the water surface and punctures the foam. The water body moves downward due to resistance and is drawn into the annular adsorption plate 53. After the annular adsorption plate 53 absorbs grease, the water body flows out from the pores, avoiding the problem of small contact area between the conventional adsorption panel and the foam, resulting in low adsorption efficiency and incomplete adsorption. Due to the rotation of the aeration pipe, the spoiler scraper 341 drives the water body to rotate, so that the grease foam on the surface of the water body slowly rotates around the center of the pool body 1, so that the foam impacts the adsorption mechanism 5 rotating in the opposite direction, avoiding the water-blocking curved panel 52 pushing the water body and pushing the foam away when rotating.

[0039] Working principle: When in use, the sewage is drained into the pool body 1 through the water inlet, and then the device is started. The gas is transported to the annular aeration pipe 34 and the aeration plate 32 through the main aeration pipe 31, and the aeration operation is performed through the aeration holes 322, so that the water body and the gas are in contact and fused, and in contact with the composite filler layer 2, so as to achieve the purification of the sewage. The aeration plate 32 is aerated with pressure through the arranged air-blocking component 6, and the recoil force is formed to drive the annular aeration pipe 34 to rotate, and then drive the spoiler scraper 341 to rotate, disturbing the water body and the microbial community at the bottom of the pool body 1, and the vibration generated by the pressure aeration makes the microorganisms diffuse into the water body more quickly. Through the transmission of the reversing component 45, the annular aeration pipe 34 drives the reversing drive rod 42 to rotate in the opposite direction, and then drives the adsorption mechanism 5 on the upper part of the pool body 1 to rotate in the opposite direction relative to the water body to puncture and adsorb the grease foam on the surface of the water body.
