Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of biological filter tanks, and particularly relates to a biological filter tank with self-leveling filter materials. Background Art
[0002] The aerated biological filter is a biological filter that combines contact oxidation and filtration. It uses artificial aeration, intermittent backwashing and other measures to mainly remove organic pollutants and suspended solids. The pool is filled with granular filter carriers to form a fixed bed, and the microbial community attaches to the surface of the carrier to form a biofilm. Aeration and oxygenation are carried out in the middle and lower part of the filter layer. As the operating time increases, the bottom of the aerated biological filter will be blocked and water cannot enter after the filter media is lost. Backwashing is required to flush away the aging biofilm and the overflowing debris.
[0003] However, there are some problems with the existing technology: since it is necessary to introduce a large amount of air during backwashing, the filter material on the surface of the pool body is uneven, so it is necessary to perform a leveling operation to achieve a stable state of water discharge from the filter material and microorganisms. However, the traditional leveling method is for workers to use tools to enter the filter body to perform the operation, which is not only time-consuming and labor-intensive, but certain gases in the filter tank that are harmful to the human body can also easily harm the workers. Therefore, we propose a biological filter with self-leveling filter material. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a biofilter with self-leveling filter material, in which the granular filter material is flattened by a pressing plate, thereby reducing the labor intensity of the staff and improving the work efficiency.
[0005] The utility model is implemented as follows: a biological filter tank with self-leveling filter material comprises a tank body, a supporting layer is arranged inside the tank body, granular filter material is laid on the supporting layer, a compacting mechanism and a driving mechanism are arranged on the tank body, the compacting mechanism and the driving mechanism are connected by a belt, the compacting mechanism comprises a circular shaft, the circular shaft is rotatably connected to the tank body, a circular shaft is fixedly connected to a circular disc, a square plate is arranged in the inner cavity of the tank body, a connecting rod is hinged between the circular disc and the square plate, a pressing plate is arranged at the bottom of the square plate, and the driving mechanism comprises a driving motor, and the driving motor is fixedly mounted on the surface of the tank body.
[0006] Optionally, a guide rod is fixedly connected to the pressure plate, and the top of the guide rod passes through the square plate.
[0007] Optionally, a spring is movably sleeved on the outer surface of the guide rod, and two ends of the spring are respectively fixedly connected to the surfaces of the square plate and the pressure plate.
[0008] Optionally, the output shaft of the driving motor is fixedly sleeved with a rotating shaft, the other end of the rotating shaft passes through the pool body and is fixedly sleeved with a driving wheel, and a stirring frame is fixedly installed on the surface of the rotating shaft.
[0009] Optionally, a driven wheel is fixedly sleeved on the circular shaft, and the belt transmission is connected between the driven wheel and the driving wheel.

[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The utility model provides a square plate, a connecting rod and a pressure plate, and the circular shaft can be rotated by a driving mechanism, so that the circular disc drives the connecting rod to rotate, and then the square plate drives the pressure plate to reciprocate up and down. Due to the movement of the pressure plate, the top of the granular filter material will be squeezed and impacted, so that the uneven part of the top of the granular filter material can be leveled, without the need for staff to use tools for leveling, and also avoiding certain gases harmful to the human body in the filter tank from harming the staff.

DETAILED DESCRIPTION
[0019] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0020] like Figures 1 to 4As shown, a biofilter with self-leveling filter material provided by an embodiment of the utility model comprises a tank body 1, a supporting layer 2 is arranged inside the tank body 1, a granular filter material 3 is laid on the supporting layer 2, a compacting mechanism and a driving mechanism are arranged on the tank body 1, the compacting mechanism and the driving mechanism are connected by a belt 4, the compacting mechanism comprises a circular shaft 5, the circular shaft 5 is rotatably connected to the tank body 1, a circular disc 7 is fixedly connected to the circular shaft 5, a square plate 8 is arranged in the inner cavity of the tank body 1, a connecting rod 9 is hinged between the circular disc 7 and the square plate 8, a pressing plate 10 is arranged at the bottom of the square plate 8, and the driving mechanism comprises a driving motor 13, and the driving motor 13 is fixedly mounted on the surface of the tank body 1.
[0021] Furthermore, a guide rod 11 is fixedly connected to the pressing plate 10 , and the top of the guide rod 11 passes through the square plate 8 .
[0022] Furthermore, a spring 12 is movably sleeved on the outer surface of the guide rod 11, and the two ends of the spring 12 are respectively fixedly connected to the surface of the square plate 8 and the pressure plate 10. Through the design of the guide rod 11 and the spring 12, there is a buffer space between the square plate 8 and the pressure plate 10. When the disc 7 drives the connecting rod 9 to rotate, the square plate 8 drives the pressure plate 10 to reciprocate up and down, so that the pressure plate 10 can hit and squeeze the granular filter material 3. When there is an uneven bulge on the top of the granular filter material 3, the pressure plate 10 cannot drop to the lowest point of the normal stroke, so it will squeeze the spring 12, so that the distance between the pressure plate 10 and the square plate 8 is reduced, thereby ensuring that the disc 7 can continue to rotate without getting stuck.
[0023] Furthermore, the output shaft of the driving motor 13 is fixedly sleeved with a rotating shaft 14, the other end of the rotating shaft 14 penetrates the pool body 1 and is fixedly sleeved with a driving wheel 15, and a stirring frame 16 is fixedly installed on the surface of the rotating shaft 14. By starting the driving motor 13, the rotating shaft 14 can drive the stirring frame 16 to rotate, so that the granular filter material 3 can be stirred, and the gaps between the granular filter materials 3 can be reduced to achieve a better leveling effect.
[0024] Furthermore, a driven wheel 6 is fixedly sleeved on the circular shaft 5, and a belt 4 is connected between the driven wheel 6 and the driving wheel 15. When the driving motor 13 is started to rotate the driving wheel 15, the driven wheel 6 and the circular shaft 5 can be driven to rotate together through the belt 4, so that the disc 7 can drive the connecting rod 9 to rotate.
[0025] Further, the stirring frame 16 is arranged in an arc shape, and the stirring frame 16 is evenly distributed on the surface of the rotating shaft 14. The stirring frame 16 is in an arc shape, and a cavity is formed between the stirring frame 16 and the rotating shaft 14, so that the resistance during rotation can be reduced.
[0026] During use, when it is necessary to level the granular filter material 3, the staff can start the drive motor 13. Due to the operation of the drive motor 13, the rotating shaft 14 will drive the driving wheel 15 and the stirring frame 16 to rotate. Due to the rotation of the stirring frame 16, the granular filter material 3 will be stirred to reduce the gap between the granular filter materials 3 and improve the subsequent leveling effect. Due to the rotation of the driving wheel 15, the belt 4 will drive the driven wheel 6 to rotate, so that the circular shaft 5 can drive the disc 7 to rotate together, and then the connecting rod 9 can drive the square plate 8 to reciprocate up and down, so that the pressing plate 10 will reciprocate up and down to hit and squeeze the top of the granular filter material 3, thereby achieving the leveling of the uneven top of the granular filter material 3.
[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
