Description

Technical Field

[0001] This utility model relates to the technical field of microbial biofilm attachment devices, and in particular to a microbial biofilm attachment device that is easy to clean. Background Technology

[0002] In recent years, river surface water ecosystems have suffered varying degrees of damage. To restore or maintain river channels, biofilms are often placed in the waterways. In traditional biofilm devices, microorganisms are typically used to purify river wastewater. Microbial carriers are placed in containers, and river water is introduced into the containers. The microorganisms purify the river water, and then the water carrying the microorganisms is returned to the river, thus completing the biofilm process.

[0003] However, microbial carriers require regular cleaning during prolonged use to prevent microbial imbalance or excessive biofilm thickness. Most biofilm attachment devices typically fix the biological carrier to the support frame during use, resulting in a complex structure that is difficult to disassemble and clean, thus reducing cleaning efficiency. To better address these issues and promote the development of industry technology and enhance core competitiveness, this application proposes a new compositional structure that differs from existing technologies.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 A microbial biofilm attachment device that is easy to clean includes a cylinder 1, a fixing frame 7 fixedly connected to the outside of the cylinder 1, and an inspection door 2 opened on the outside of the cylinder 1.

[0024] The bottom of the cylinder 1 is rotatably connected to a rotating shaft 13 via a bearing. Two slides 9 are fixed to the outside of the rotating shaft 13 by bolts. Both ends of the two slides 9 are provided with slide grooves 21. Two first slides 23 and second slides 29 are slidably connected in the multiple slide grooves 21. A biological carrier 8 is provided on one side of the two first slides 23 and the second slides 29. The biological carrier 8 refers to a substance that enables microorganisms to attach, grow and form a biofilm, such as common biological fillers and microbial carriers. It has a large specific surface area to increase the attachment space and increase the contact area between sewage and biofilm, thereby improving the effect of microbial sewage purification.

[0025] The biological carrier 8 can be placed inside a metal mesh tube, which is fixedly connected to the first slider 23 and the second slider 29;

[0026] Guide rods 28 are inserted into both sides of the second slider 29. The guide rods 28 are rubber rods and pass through the first slider 23 and are slidably connected to the first slider 23.

[0027] Two U-shaped frames 22 are rotatably connected to one side of each of the two slides 9 via a pivot. Fixing blocks 18 corresponding to the U-shaped frames 22 are welded to the other side of the two slides 9. Pins 17 are slidably connected inside the multiple fixing blocks 18, and the pins 17 pass through one end of the U-shaped frame 22.

[0028] The top of the second slider 29 is provided with an adjustment component for adjusting the distance between the sliders, and the bottom of the cylinder 1 is provided with a drive component for rotating the shaft 13. When in use, the inspection door 2 is opened, then the nut 19 is loosened, the pin 17 is pulled out, and then the first slider 23 and the second slider 29 are pulled out, thereby completing the disassembly and cleaning of the biological carrier 8 and increasing the cleaning efficiency.

[0029] The adjustment assembly includes bolts 26, which are rotatably connected to the top of the second slider 29 via bearings. Threaded blocks 27 are threaded to the outer sides of multiple bolts 26, and connecting rods 25 are rotatably connected to both sides of the multiple threaded blocks 27. Mounting blocks 24 are welded to the top of multiple first sliders 23, and one end of each connecting rod 25 is rotatably connected to the first slider 23. In use, rotating the bolts 26 causes the threaded blocks 27 to move. Since the connecting rods 25 are rotatably connected to the threaded blocks 27, and one end of the connecting rods 25 rotates with the first slider 23, when the threaded blocks 27 move upward, they will drive the connecting rods 25 to move together, thereby causing the two first sliders 23 to move towards each other. This adjusts the distance between the biological carriers 8, thereby promoting the growth of heterotrophic bacteria by expanding the spacing, strengthening the dominant nitrifying bacteria population by compressing the spacing, and increasing the applicability of the device.

[0030] The drive assembly includes a rotating blade 11, which is keyed to the bottom of the rotating shaft 13. The bottom of the cylinder 1 is fixed to the housing 12 by bolts, and the rotating blade 11 is located inside the housing 12. A conveying pipe 14 is welded to the outside of the housing 12. A valve is installed on the conveying pipe 14. The conveying pipe 14 can be directly aligned with the river or can be used in conjunction with other sewage conveying equipment to deliver river water carrying microorganisms out of the device.

[0031] In use, the rotating blade 11 is rotated by the impact of the river water, which drives the rotating shaft 13 to rotate, thereby causing the slide 9 to drive the biological carrier 8 to rotate.

[0032] In this utility model, a water pump 4 is provided at the top of the cylinder 1 and the water pump 4 is connected to the inside of the cylinder 1. A water inlet pipe 10 is welded to the bottom of the cylinder 1. When in use, the water pump 4 draws river water from the river channel into the shell 12. The river water enters the shell 12 axially through the conveying pipe 14 to impact the rotating blades 11. Then, it enters the cylinder 1 through the water inlet pipe 10. A detachable guardrail 15 is fixed to one side of the conveying pipe 14 with bolts. The guardrail 15 can intercept garbage and water plants in the river channel. When the water flow rate is observed to slow down, the valve can be closed and the cylinder can be disassembled for cleaning.

[0033] Each of the multiple pins 17 has a threaded groove 20 at its bottom, and each of the multiple threaded grooves 20 is threaded with a nut 19, which can lock the pin 17 by the cooperation of the nut 19 and the threaded groove 20.

[0034] Two hinges 3 are fixed to the outside of the cylinder 1 by bolts, and the other end of the hinges 3 is fixed to the inspection door 2. A buckle 5 is fixed to the outside of the cylinder 1 by bolts, and the other end of the buckle 5 is fixed to the inspection door 2. A handle 6 is fixed to one side of the inspection door 2 by bolts. When in use, the buckle 5 is opened and the handle 6 is pulled to make the inspection door 2 rotate and open through the hinges 3, which increases the convenience of the device.

[0035] Working principle: When it is necessary to carry out microbial biofilm formation on the river water, close the valve on the delivery pipe 14, start the water pump 4, and use the pumping force of the water pump 4 to drive the river water through the delivery pipe 14 into the shell 12 axially. Place part of the shell 12 underwater until the sewage completely covers all the biological carriers 8. Then open the valve, and the water pump 4 continues to carry water. As the river water enters the shell 12 axially, the rotating blades 11 will rotate due to the impact of the river water. The rotating blades 11 will drive the rotating shaft 13 to rotate, thereby causing the slide 9 to drive the biological carriers 8 to rotate. Through the contact between the biological carriers 8 and the river water, the microorganisms will flow away with the river water, which will facilitate the subsequent sewage to return to the river and the microorganisms to purify the river water.

[0036] When it is necessary to clean the biological carrier 8, open the latch 5, pull the handle 6 to open the access door 2 by rotating the hinge 3, then loosen the nut 19, pull out the pin 17, and then pull out the first slider 23 to disassemble and clean the biological carrier 8, thereby increasing the cleaning efficiency.

[0037] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
