Description

Technical Field

[0001] This utility model relates to the field of river water purification technology, specifically a river water purification device based on a biofilm. Background Technology

[0002] Rivers are areas where rainwater or water that springs from underground collects in low-lying areas and flows regularly or periodically along the depressions created by the water itself under the influence of gravity. With industrial development and the increase in urban population, a large amount of pollutants are discharged into rivers. Therefore, it is necessary to purify the water quality of rivers through biofilm purification devices.

[0003] Traditional purification devices work by installing a biofilm inside the housing, allowing river water to enter through the inlet pipe, filtering the water through the biofilm, and then discharging it through the outlet pipe.

[0004] However, traditional purification devices mostly use bolts to install biofilms. This means that during installation, not only must the biofilm be precisely aligned with the mounting holes on the shell, but also each bolt must be tightened with the same force to prevent uneven stress on the biofilm and damage. In addition, frequent use of bolts to install and remove the biofilm can easily lead to wear and stripping of the mounting holes, resulting in reduced installation effectiveness and making it inconvenient to install the biofilm. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a river water purification device based on a biofilm. It solves the problems of traditional purification devices, which require precise alignment of the biofilm with the mounting holes on the shell during biofilm installation, as well as ensuring that each bolt is tightened with consistent force to prevent damage to the biofilm due to uneven stress. Furthermore, frequent use of bolts to install and remove the biofilm can easily lead to wear and stripping of the mounting holes, making biofilm installation inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biofilm-based river water purification device, comprising a shell, with an inlet pipe and an outlet pipe respectively connected to one side and the bottom of the shell, and a biofilm disposed inside the shell. The biofilm-based river water purification device further includes an installation mechanism located at the top of the shell; a sealing mechanism located inside the shell; and a buffer mechanism located on the side of the shell near the inlet pipe. The installation mechanism facilitates the installation of the biofilm, the sealing mechanism improves the sealing performance during biofilm installation, and the buffer mechanism protects the biofilm. The installation mechanism includes a housing, which is fixed... The frame is attached to the top of the shell; both ends of the rotating shaft are rotatably connected to the inner wall of the housing via bearings; there are two worm gears, each rotatably connected to the inner wall of the housing via bearings; there are two worm wheels, each meshing with the bottom of the two worm gears and fixed to the outer wall of the rotating shaft; there are two crossbars, each fixed to the outer wall of the rotating shaft and extending to the outside of the housing through an opening; the top of the frame is inserted into the inside of the crossbars, and the inner wall is fixed to the outer wall of the biofilm and inserted into the inner wall of the shell; the drive assembly is located outside the housing; wherein, the frame containing the biofilm is inserted into the shell, and the worm wheels, driven by the worm gears, cause the rotating shaft to drive the crossbars to rotate and insert into the frame.

[0007] Preferably, the drive assembly includes a connecting column, which is rotatably connected to the inner wall of the housing via a bearing; a handwheel is fixed to the beginning of the connecting column; a first gear is fixed to the inner wall of the connecting column; and two second gears are respectively fixed to the outer walls of the two worm gears; wherein, under the drive of the handwheel, the connecting column causes the first gear to drive the second gear to rotate, thereby causing the worm gear to rotate.

[0008] Preferably, the sealing mechanism includes a first sealing gasket, which is fixed to the lower inner wall of the housing and the inner wall is attached to the bottom of the frame; a second sealing gasket is fixed to the upper inner wall of the housing and the top is attached to the upper outer wall of the frame; wherein, the cooperation of the first sealing gasket and the second sealing gasket improves the sealing performance of the frame.

[0009] Preferably, the buffer mechanism includes a support column, which is fixed to the top of the inner wall of the housing near the water inlet pipe; an arc-shaped plate is rotatably connected to the outer wall of the support column via a pin; an elastic sheet is fixed to the upper side wall of the arc-shaped plate by bolts; a mounting column is fixed to the top of the inner wall of the housing near the support column, and its outer wall is fixed to one side of the elastic sheet by bolts; and an auxiliary component is disposed on one side of the arc-shaped plate; wherein, the arc-shaped plate and the elastic sheet buffer the river water and reduce the impact force of the river water.

[0010] Preferably, the auxiliary component includes a first baffle fixed to the inner wall of the housing near the side of the arc-shaped plate; and a second baffle fixed to the inner wall of the housing near the side of the first baffle; wherein the first baffle and the second baffle further reduce the impact force of the river water. Beneficial effects

[0011] This invention provides a biofilm-based river water purification device. It offers the following advantages: This biofilm-based river water purification device, through the cooperation of a housing, worm gear, worm wheel, rotating shaft, cross column, frame, and drive assembly, facilitates the installation of the biofilm. It solves the problems of traditional purification devices, which require precise alignment of the biofilm with the mounting holes on the housing, consistent tightening of each bolt to prevent damage due to uneven stress, and frequent bolt installation and removal that easily leads to wear and stripping of the mounting holes, making biofilm installation inconvenient.

[0012] By combining curved plates, support columns, elastic sheets, mounting columns, and auxiliary components, the impact force of river water is reduced, protecting the biofilm. This solves the problem that when purifying river water, the water rushes directly into the device from the inlet pipe, and the turbulent water flow acts on the biofilm with a large impact force, which not only easily damages the structure of the biofilm and causes its microbial community to become unbalanced, but also reduces its ability to degrade pollutants.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Traditional purification devices require precise alignment of the biofilm with the mounting holes on the housing during installation. They also need to ensure that each bolt is tightened to the same degree to prevent damage to the biofilm due to uneven stress. Furthermore, frequent use of bolts to install and remove the biofilm can easily lead to wear and stripping of the mounting holes, making it inconvenient to install the biofilm.

[0021] In view of this, the present invention provides a river water purification device based on a biofilm. Through the cooperation of the housing, worm gear, worm wheel, rotating shaft, cross column, frame and drive assembly, it realizes convenient installation of biofilm. It solves the problems of traditional purification devices, which require precise alignment of biofilm with the installation holes on the housing and ensure that the tightening force of each bolt is consistent to prevent damage to the biofilm due to uneven stress. Moreover, frequent use of bolts to install and remove biofilm can easily lead to wear and stripping of the installation holes, making it inconvenient to install biofilm.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-5It is known that a biofilm-based river water purification device includes a shell 1, with an inlet pipe 2 and an outlet pipe 4 connected to one side and bottom of the shell 1, respectively. A biofilm 3 is disposed inside the shell 1. The biofilm-based river water purification device also includes an installation mechanism 5, a sealing mechanism 6, and a buffer mechanism 7. The installation mechanism 5 is located at the top of the shell 1; the sealing mechanism 6 is located inside the shell 1; and the buffer mechanism 7 is located on the side of the shell 1 near the inlet pipe 2. The installation mechanism 5 facilitates the installation of the biofilm 3, the sealing mechanism 6 improves the sealing performance during installation, and the buffer mechanism 7 protects the biofilm 3. The installation mechanism 5 includes a housing 51, a worm gear 52, a worm wheel 53, a rotating shaft 54, a cross column 55, a frame 56, and a drive assembly 57. The housing 51... The frame 56 is fixed to the top of the housing 1; both ends of the rotating shaft 54 ​​are rotatably connected to the inner wall of the housing 51 via bearings; there are two worm gears 52, both of which are rotatably connected to the inner wall of the housing 51 via bearings; there are two worm wheels 53, which are respectively meshed with the bottom of the two worm gears 52 and fixed to the outer wall of the rotating shaft 54; there are two cross columns 55, both of which are fixed to the outer wall of the rotating shaft 54 ​​and extend to the outside of the housing 51 through an opening; the top of the frame 56 is inserted into the inside of the cross columns 55, and the inner wall is fixed to the outer wall of the biofilm 3 and inserted into the inner wall of the housing 1; the drive assembly 57 is located outside the housing 51; wherein, the frame 56 containing the biofilm 3 is inserted into the housing 1, and the worm wheels 53, driven by the worm gears 52, cause the rotating shaft 54 ​​to drive the cross columns 55 to rotate and insert into the frame 56;

[0024] In the specific implementation process, it is worth noting that the staff installs multiple biofilms 3 into the shell 1 through the installation mechanism 5. The biofilm 3 is made of porous polyurethane sponge, which is an ideal material with a three-dimensional network structure. The interior is filled with a large number of interconnected pores, and the specific surface area can reach tens of square meters per gram, which can provide sufficient attachment space for microorganisms. At the same time, the surface of polyurethane sponge has good hydrophilicity and stable chemical properties, and will not inhibit the growth and metabolism of microorganisms. This is conducive to the formation of a stable biofilm 3 structure on its surface. After completion, the staff opens the valves on the inlet pipe 2 and the outlet pipe 4. River water enters the shell 1 through the inlet pipe 2. The impact force of the river water is reduced by the buffer mechanism 7. The biofilm 3 adsorbs impurities in the river water and purifies the river water. After completion, the river water is discharged from the shell 1 through the outlet pipe 4.

[0025] Specifically, the staff installs multiple biofilms 3 into the shell 1 through the installation mechanism 5. River water enters the shell 1 through the inlet pipe 2. The impact force of the river water is reduced by the buffer mechanism 7. The biofilms 3 adsorb impurities in the river water and purify the river water. After completion, the river water is discharged from the shell 1 through the drain pipe 4.

[0026] Specifically, when installing the biofilm 3, the worker first holds the through slot at the top of the frame 56 and inserts the frame 56 containing the biofilm 3 into the housing 1. After that, the worm gear 52 is rotated, which drives the worm wheel 53 to rotate. The worm wheel 53 drives the rotating shaft 54 ​​to rotate. The rotating shaft 54 ​​is locked after rotation by the self-locking of the worm gear 52 and the worm wheel 53. The rotating shaft 54 ​​drives the horizontal column 55 to rotate. The horizontal column 55 is inserted into the top of the frame 56, pressing down and fixing the frame 56, thus facilitating the installation of the biofilm 3.

[0027] Example 2: From Figure 1-5 It is known that the drive assembly 57 includes a connecting column 571, a first gear 572, a second gear 573, and a handwheel 574. The connecting column 571 is rotatably connected to the inner wall of the housing 51 via bearings; the handwheel 574 is fixed to the beginning of the connecting column 571; the first gear 572 is fixed to the inner wall of the connecting column 571; there are two second gears 573, which are respectively fixed to the outer walls of two worm gears 52; wherein, under the drive of the handwheel 574, the connecting column 571 causes the first gear 572 to drive the second gear 573 to rotate, thereby causing the worm gears 52 to rotate.

[0028] In the specific implementation process, it is worth noting that when the staff turns the handwheel 574, the handwheel 574 drives the connecting column 571 to rotate, the connecting column 571 drives the first gear 572 to rotate, the first gear 572 drives the second gear 573 to rotate, and the two second gears 573 drive the worm gear 52 to rotate, thereby driving the installation mechanism 5 to work.

[0029] Furthermore, the sealing mechanism 6 includes a first sealing gasket 61 and a second sealing gasket 62. The first sealing gasket 61 is fixed to the lower inner wall of the housing 1, and the inner wall is attached to the bottom of the frame 56. The second sealing gasket 62 is fixed to the upper inner wall of the housing 1, and the top is attached to the upper outer wall of the frame 56. The cooperation of the first sealing gasket 61 and the second sealing gasket 62 improves the sealing performance of the frame 56.

[0030] In the specific implementation process, it is worth noting that the first sealing gasket 61 and the second sealing gasket 62 are made of highly elastic and water-resistant rubber material. When the frame 56 is inserted into the housing 1, the first sealing gasket 61 and the second sealing gasket 62 are attached to the outer wall of the frame 56, effectively filling the gap between the frame 56 and the housing 1, preventing water from leaking from the connection, and improving the sealing between the frame 56 and the housing 1.

[0031] Furthermore, the buffer mechanism 7 includes an arc-shaped plate 71, a support column 72, an elastic sheet 73, a mounting column 74, and an auxiliary component 75. The support column 72 is fixed to the top of the inner wall of the housing 1 near the water inlet pipe 2. The arc-shaped plate 71 is rotatably connected to the outer wall of the support column 72 via a pin. The elastic sheet 73 is fixed to the upper side wall of the arc-shaped plate 71 by bolts. The mounting column 74 is fixed to the top of the inner wall of the housing 1 near the support column 72, and its outer wall is fixed to one side of the elastic sheet 73 by bolts. The auxiliary component 75 is disposed on one side of the arc-shaped plate 71. The arc-shaped plate 71 and the elastic sheet 73 buffer the river water and reduce the impact force of the river water.

[0032] In the specific implementation process, it is worth noting that when the river water enters the shell 1 from the inlet pipe 2, the water flow first impacts the arc plate 71. At this time, under the impact of the water flow, the arc plate 71 rotates around the pin on the support column 72. The arc plate 71 drives the elastic sheet 73 to produce elastic deformation, thereby absorbing the water flow energy, reducing the impact force of the water flow, and reducing the impact force of the river water to protect the biofilm 3.

[0033] Furthermore, the auxiliary component 75 includes a first baffle 751 and a second baffle 752. The first baffle 751 is fixed to the inner wall of the housing 1 on the side near the arc-shaped plate 71; the second baffle 752 is fixed to the inner wall of the housing 1 on the side near the first baffle 751. The impact force of the river water is further reduced by the first baffle 751 and the second baffle 752.

[0034] In the specific implementation process, it is worth noting that the surfaces of the first baffle 751 and the second baffle 752 are provided with holes. The holes on the surface of the first baffle 751 are larger than the holes on the surface of the second baffle 752. When the river water is buffered by the arc plate 71, it first flows through the first baffle 751, then through the second baffle 752, and finally comes into contact with the biofilm 3. This allows the first baffle 751 and the second baffle 752 to further block and divert the water flow, change the direction of the water flow, and disperse the impact force of the water flow.

[0035] Specifically, during the installation of the biofilm 3, the worker first holds the through slot at the top of the frame 56 and inserts the frame 56 containing the biofilm 3 into the housing 1. Then, the worker turns the handwheel 574, which drives the connecting column 571 to rotate. The connecting column 571 drives the first gear 572 to rotate, which in turn drives the second gear 573 to rotate. The two second gears 573 drive the worm gear 52 to rotate, which in turn drives the worm wheel 53 to rotate. The worm wheel 53 drives the rotating shaft 54 ​​to rotate, which in turn drives the horizontal column 55 to rotate. The horizontal column 55 is inserted into the top of the frame 56, pressing the frame 56 down and fixing it in place. At the same time, the first sealing gasket 61... The second sealing gasket 62 is attached to the outer wall of the frame 56, effectively filling the gap between the frame 56 and the shell 1, preventing water leakage from the connection. After installation, when river water enters the shell 1 from the inlet pipe 2, the water flow first impacts the arc plate 71. At this time, under the impact of the water flow, the arc plate 71 rotates around the pin on the support column 72. The arc plate 71 drives the elastic sheet 73 to produce elastic deformation, thereby absorbing the water flow energy and reducing the impact force of the water flow. At the same time, the river water buffered by the arc plate 71 first flows through the first baffle 751, then through the second baffle 752, and finally comes into contact with the biofilm 3 to purify the river water.

[0036] 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.
