Description

Technical Field

[0001] The utility model relates to the technical field of biological turntables, in particular to a biological turntable used for treating micro-polluted water bodies in rivers. Background Art

[0002] Bio-disc equipment is usually used in the process of treating micro-polluted water bodies in rivers. The sewage in the river is transported to the inside of the bio-disc equipment through a water pump. The discs in the bio-disc can form biofilm and degrade pollutants under micro-pollutant conditions, thereby improving the water quality. Finally, the water treated by the bio-disc is discharged back into the river.

[0003] For example, a Chinese utility model patent disclosed in the Chinese patent publication number CN219689484U and the authorization announcement date September 15, 2023 discloses a biological turntable for treating micro-polluted water bodies in rivers, which belongs to the field of biological turntable technology. Its technical scheme is: it includes a biological turntable body, and a water inlet buffer waterfall mechanism is arranged at the water inlet of the biological turntable body. The water inlet buffer waterfall mechanism includes a hollow shell, and a water flow inlet is arranged on one side of the shell, and the water flow inlet is connected to the water inlet; a water flow outlet is arranged on the other side of the shell opposite to the water flow inlet, and an overflow weir is detachably installed on the water flow outlet.

[0004] Although the above-mentioned biological turntable reduces the water flow rate at the water inlet end of the sewage tank by setting a water inlet buffer waterfall mechanism at the water inlet, thereby reducing the impact on the microorganisms attached to the disc inside the sewage tank and reducing problems such as biofilm shedding caused by the impact, the above-mentioned biological turntable does not have a filtering mechanism at the water inlet. Since the sewage in the river contains a lot of solid waste such as mud, dead branches and leaves, if these solid wastes directly enter the biological turntable, they will come into contact with the disc in the biological turntable. In this way, the microorganisms attached to the disc will be continuously washed away by the solid waste, which will lead to the shedding of the biofilm, which will affect the sewage treatment effect of the biological turntable. Utility Model Content

[0005] The utility model aims to provide a biological rotating disk used for treating slightly polluted water bodies in rivers, so as to solve the problem that solid wastes in sewage easily cause the biofilm on the biological rotating disk to fall off.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a biological turntable used for treating micro-polluted water bodies in rivers, comprising a reaction tank, one end of the reaction tank is connected to a water storage tank, one end of the water storage tank is connected to a filter box, one end of the inner wall of the filter box is rotatably connected to a conveyor belt, the conveyor belt is inclined, and one end extends to the outside of the filter box, a plurality of filter holes are provided on the surface of the conveyor belt, a plurality of baffles are fixedly connected to the surface of the filter box, a first motor is fixedly connected to one end of the outer wall of the filter box, the output end of the first motor is fixedly connected to the input shaft of the conveyor belt, the filter box is located above the conveyor belt and is fixedly connected to a water pump, and a connecting pipe is provided at the output end of the water pump.

[0007] Preferably, a second motor is fixedly connected to one end of the reaction tank away from the water tank, a rotating shaft is fixedly connected to the output end of the second motor, and a plurality of discs are fixedly connected to the middle of the rotating shaft.

[0008] Preferably, the filter box is provided with a first through hole at the bottom of one end of the water storage tank, and the filter box is connected with the water storage tank through the first through hole.

[0009] Preferably, a support plate is fixedly connected to one end of the top of the filter box, and the support plate is fixedly connected to the water pump.

[0010] Preferably, two support arms are fixedly connected to one end of the side wall of the filter box, and the support arms are rotatably connected to the conveyor belt.

[0011] Preferably, the water storage tank is provided with a plurality of second through holes at one end of the reaction tank, and the water storage tank is connected with the reaction tank via the second through holes.

[0012] Preferably, a drain pipe is provided at the bottom of one end of the reaction tank away from the water storage tank.

[0013] Preferably, four supporting legs are fixedly connected to the bottom of the reaction tank.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model arranges a filter box, a conveyor belt and a filter hole at one end of the water inlet of the reaction tank, so that the solid waste in the sewage can be intercepted by the conveyor belt before entering the reaction tank, thereby preventing the solid waste from scouring the disc in the reaction tank, thereby avoiding the biofilm on the disc from falling off. In addition, the conveyor belt can be driven to rotate by the first motor, so that the intercepted solid waste is discharged from the filter box, thereby avoiding the accumulation of solid waste in the filter box, thereby blocking the filter hole on the conveyor belt. In addition, the design of the water storage tank allows the sewage to have a buffering effect before entering the reaction tank, thereby preventing the water flow speed from being too fast and scouring the biofilm on the disc. The design of the first through hole allows the filtered sewage to smoothly enter the water storage tank from the filter box, and the design of the second through hole allows the sewage in the water storage tank to smoothly enter the reaction tank, wherein the first through hole is located at the bottom of the side wall of the water storage tank, and the second through hole is located at the top of the side wall of the water storage tank, so that only after the water storage tank is full of sewage, the sewage will flow into the reaction tank through the second through hole, thereby reducing the flow speed of the sewage.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figure 1-6 The utility model provides a technical solution: a biological turntable used for treating micro-polluted water bodies in rivers, comprising a reaction tank 1, one end of the reaction tank 1 is connected to a water storage tank 2, one end of the water storage tank 2 is connected to a filter box 3, one end of the inner wall of the filter box 3 is rotatably connected to a conveyor belt 4, the conveyor belt 4 is inclined, and one end extends to the outside of the filter box 3, a plurality of filter holes 5 are arranged on the surface of the conveyor belt 4, a plurality of baffles 6 are fixedly connected to the surface of the filter box 3, a first motor 7 is fixedly connected to one end of the outer wall of the filter box 3, the output end of the first motor 7 is fixedly connected to the input shaft of the conveyor belt 4, the filter box 3 is located above the conveyor belt 4 and is fixedly connected to a water pump 8, and a connecting pipe 9 is arranged at the output end of the water pump 8,

[0025] In this embodiment, through the design of the filter box 3, the conveyor belt 4 and the filter holes 5, the solid waste in the sewage is intercepted by the conveyor belt 4 before entering the reaction tank 1. In addition, the conveyor belt 4 can be driven to rotate by the first motor 7, so that the intercepted solid waste is discharged from the filter box 3, thereby avoiding the accumulation of solid waste in the filter box 3 and blocking the filter holes 5 on the conveyor belt 4. Since the conveyor belt 4 is inclined, a plurality of baffles 6 are provided on the conveyor belt 4 to increase the friction between the conveyor belt 4 and the solid waste, thereby preventing the solid waste from rolling on the conveyor belt 4 during the conveying process. In this way, the conveyor belt 4 can smoothly discharge the solid waste from the filter box 3. In addition, through the design of the water storage tank 2, the sewage has a buffering effect before entering the reaction tank 1, thereby preventing the water flow speed from being too fast and reducing the treatment effect.

[0026] During operation, first, the input end of the water pump 8 is connected to the sewage in the river channel through a water pipe, and then the water pump 8 is turned on. Under the action of the water pump 8, the sewage in the river channel will flow out from the connecting pipe 9 and fall onto the conveyor belt 4. At this time, the liquid in the sewage will pass through the filter holes 5 on the conveyor belt 4 and fall to the bottom of the filter box 3, while the solid waste in the sewage will be intercepted by the conveyor belt 4. Then the first motor 7 is turned on, and the conveyor belt 4 will rotate under the drive of the first motor 7, thereby discharging the solid waste from the filter box 3 to the outside, and the filtered sewage will flow into the water storage tank 2. Under the action of the water storage tank 2, the flow rate of the sewage will be greatly reduced, thereby preventing the water flow rate from being too fast and reducing the treatment effect.

[0027] A second motor 10 is fixedly connected to one end of the reaction tank 1 away from the water storage tank 2, a rotating shaft 11 is fixedly connected to the output end of the second motor 10, and a plurality of discs 12 are fixedly connected to the middle of the rotating shaft 11. In the present embodiment, when sewage flows from the water storage tank 2 into the reaction tank 1, the sewage will contact the disc 12, and the disc 12 can form a biofilm and degrade pollutants under micro-pollution conditions, thereby improving the water quality. At this time, the second motor 10 is turned on, and the rotating shaft 11 will rotate under the drive of the second motor 10, thereby driving the disc 12 to rotate, thereby improving the sewage treatment efficiency of the disc 12.

[0028] The filter box 3 is located at the bottom of one end of the water tank 2 and is provided with a first through hole 13. The filter box 3 is connected to the water tank 2 through the first through hole 13. In this embodiment, the design of the first through hole 13 allows the sewage in the filter box 3 to flow smoothly into the water tank 2, wherein the first through hole 13 is located at the bottom of the side wall of the filter box 3 and below the conveyor belt 4, so that unfiltered sewage can be prevented from flowing into the water tank 2 through the first through hole 13.

[0029] A support plate 14 is fixedly connected to one end of the top of the filter box 3, and the support plate 14 is fixedly connected to the water pump 8. In this embodiment, the design of the support plate 14 allows the water pump 8 to be smoothly fixed on the top of the filter box 3 and located above the conveyor belt 4, so that the sewage transported from the water pump 8 can smoothly fall onto the conveyor belt 4 and then be filtered by the conveyor belt 4.

[0030] Two support arms 15 are fixedly connected to one end of the side wall of the filter box 3, and the support arms 15 are rotatably connected to the conveyor belt 4. In this embodiment, the support arms 15 are designed to support one end of the conveyor belt 4 extending to the outside of the filter box 3, thereby ensuring the stability of the conveyor belt 4.

[0031] The water tank 2 is located at one end of the reaction tank 1 and is provided with a plurality of second through holes 16. The water tank 2 is connected to the reaction tank 1 via the second through holes 16. In this embodiment, the design of the second through holes 16 allows the sewage in the water tank 2 to flow smoothly into the reaction tank 1, and the second through holes 16 are located at the top of the side wall of the water tank 2, so that the sewage will not immediately flow into the reaction tank 1 after entering the water tank 2, thereby playing a buffering role.

[0032] A drain pipe 17 is disposed at the bottom of one end of the reaction tank 1 away from the water storage tank 2 . In this embodiment, the design of the drain pipe 17 allows the treated sewage to be smoothly discharged from the reaction tank 1 .

[0033] Four supporting legs 18 are fixedly connected to the bottom of the reaction tank 1. In this embodiment, the reaction tank 1 is supported by the design of the supporting legs 18, thereby improving the stability of the entire structure.

[0034] Working principle: when in use, first connect the input end of the water pump 8 to the sewage in the river through a water pipe, then turn on the water pump 8. Under the action of the water pump 8, the sewage in the river will flow out from the connecting pipe 9 and fall onto the conveyor belt 4. At this time, the liquid in the sewage will pass through the filter holes 5 on the conveyor belt 4 and fall to the bottom of the filter box 3, while the solid waste in the sewage will be intercepted by the conveyor belt 4. Then turn on the first motor 7. The conveyor belt 4 will rotate under the drive of the first motor 7, thereby discharging the solid waste from the filter box 3 to the outside. Since the conveyor belt 4 is inclined, a plurality of baffles 6 are arranged on the conveyor belt 4 to increase the friction between the conveyor belt 4 and the solid waste, thereby preventing the solid waste from rolling on the conveyor belt 4 during the transmission process, so that the conveyor belt 4 can smoothly transport the solid waste. The wastewater is discharged from the filter box 3, and the filtered wastewater flows into the water storage tank 2 through the first through hole 13. When the wastewater in the water storage tank 2 increases, the water level inside the water storage tank 2 increases. When the water level in the water storage tank 2 rises to the position of the second through hole 16, the wastewater flows into the reaction tank 1 through the second through hole 16. In this way, the flow rate of the wastewater is greatly reduced under the action of the water storage tank 2, thereby avoiding the biofilm on the disc 12 from being washed away due to the excessive flow rate of the wastewater. When the wastewater enters the reaction tank 1, it contacts the disc 12. The disc 12 can form a biofilm and degrade pollutants under micro-pollution conditions, thereby improving the water quality. At this time, the second motor 10 is turned on, and the shaft 11 rotates under the drive of the second motor 10, thereby driving the disc 12 to rotate, thereby improving the wastewater treatment efficiency of the disc 12.

The scope of the present invention is defined by the appended claims and their equivalents.
