Description

Technical Field

[0001] The utility model relates to the field of deodorizing biological filters, in particular to a deodorizing biological filter. Background Art

[0002] During the wastewater treatment process, a biological filter is usually used to filter organic substances, inorganic suspended substances, colloidal particles, etc. in the wastewater. For some wastewater that emits odors, a deodorizing structure is usually arranged at the liquid inlet end of the biological membrane filter to deodorize the wastewater before it enters the biological membrane filter;

[0003] A prior art wastewater deodorizing device with the publication number CN220597064U includes a deodorizing reaction tank and a filtering tank. A protective shell is fixedly connected to the top of the filtering tank. A motor is fixedly connected to the inner top wall of the protective shell. The output end of the motor is fixedly connected to a first rotating rod that extends to the inside of the deodorizing reaction tank. A plurality of stirring rods are fixedly connected to the outer side of the first rotating rod. A first bevel gear located inside the protective shell is fixedly connected to the outer side of the first rotating rod. This wastewater deodorizing device has advantages such as good deodorizing effect, and solves the problems that in the existing wastewater deodorizing device during deodorization, due to the fixed setting of the device, the reaction time between the deodorant and the wastewater is relatively long, and since the filter plate in the filtering tank is generally in a static state and cannot move, only the wastewater in the nearby area can be adsorbed and filtered during filtration, resulting in poor filtration efficiency;

[0004] As in the above patent, the structures for deodorizing wastewater at the liquid inlet end of a biological membrane filter in the prior art usually have the following problems: Since the feeding of the deodorant in the prior art is set as static feeding and is carried out from the upper end of the mixing cylinder and then stirred and mixed, such a setting makes it take a long time for the deodorant to be fully and evenly mixed into the wastewater, greatly reducing the efficiency of the wastewater deodorization work. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the prior art problems, the purpose of the present utility model is to provide a deodorizing biological filter that can evenly feed the deodorant into the deodorizing reaction tank from top to bottom or from bottom to top in the deodorizing reaction tank.

[0006] To solve the prior art problems, the technical solution of the present utility model is as follows:

[0007] A deodorizing biological filter includes a deodorizing reaction tank and a biological filter. The liquid outlet end of the deodorizing reaction tank is connected to the liquid inlet end of the biological filter through a pipeline. A stirring assembly is rotatably installed on the inner wall of the deodorizing reaction tank. A feeding assembly for feeding the deodorant into the inner side of the deodorizing reaction tank from bottom to top or from top to bottom is installed on the stirring assembly.

[0008] Preferably, the stirring assembly includes a rotating shaft rotatably connected to the inner wall of the deodorization reaction tank through a bearing.

A worm is rotatably connected to the top of the deodorization reaction tank through a bearing. The worm gear is meshed with the worm. A motor is fixed at the top of the deodorization reaction tank. One end of the worm is fixed to the output end of the motor.

[0010] Preferably, the feeding assembly includes a first inner cavity formed in the middle of the rotating shaft. A second inner cavity is formed in the middle of the stirring blade. The first inner cavity is communicated with the second inner cavity. A plurality of discharge ports are equidistantly formed on one side of the stirring blade. A sealing plate is slidably mounted on the outer wall of the stirring blade near the discharge port. A plurality of communication grooves are equidistantly formed on the sealing plate. The communication grooves are matched with the discharge ports. A moving assembly for driving the sliding of the sealing plate to switch between the first state of opening the discharge port and the second state of closing the discharge port is fixed on the outer wall of the stirring blade.

The roller abuts against the inner wall of the deodorization reaction tank. Two sets of driving arc-shaped blocks are symmetrically fixed on the inner wall of the deodorization reaction tank. Each set of driving arc-shaped blocks is distributed in a stepped manner from top to bottom on the inner side of the deodorization reaction tank. The driving arc-shaped blocks are matched with the rollers.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] When the feeding assembly provided in the present application feeds the deodorant, the effect of uniformly feeding the deodorant from top to bottom or from bottom to top in the deodorization reaction tank can be achieved, so that the deodorant can be quickly distributed in the wastewater at each layer position in the deodorization reaction tank, and the efficiency of mixing the deodorant and the wastewater evenly is improved;

Detailed Embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Please refer to Figures 1 to 8 , this embodiment provides a deodorizing biological filter 2, including a deodorization reaction tank 1 and a biological filter 2. The liquid outlet end of the deodorization reaction tank 1 is connected and communicated with the liquid inlet end of the biological filter 2 through a pipeline. A stirring component 3 is rotatably installed on the inner wall of the deodorization reaction tank 1;

[0027] The biological filter 2 is a prior art, and its specific structure and working principle will not be elaborated here;

[0028] In the deodorization filtration work, the wastewater enters the deodorization reaction tank 1 for deodorization. After the deodorization is completed, it enters the biological filter 2 through a pipeline for filtration. A valve can be installed on the pipeline between the deodorization reaction tank 1 and the biological filter 2 to control the opening and closing, and the valve is not shown in the figure;

[0029] The stirring assembly 3 includes a rotating shaft 31 rotatably connected to the inner wall of the deodorization reaction tank 1 through a bearing. Two groups of stirring blades 32 are symmetrically fixed on the outer wall of the rotating shaft 31. Each group of stirring blades 32 is arranged at equal intervals from top to bottom on the outside of the rotating shaft 31. A rotating assembly 33 for driving the rotating shaft 31 to rotate is fixed on the top of the deodorization reaction tank 1;

[0030] The rotating assembly 33 includes a worm gear 331 fixed on the outer wall of the upper end of the rotating shaft 31. A worm 332 is rotatably connected to the top of the deodorization reaction tank 1 through a bearing. The worm gear 331 is meshed with the worm 332. A motor 333 is fixed on the top of the deodorization reaction tank 1, and one end of the worm 332 is fixed to the output end of the motor 333;

[0031] During the mixing work in the process of adding the deodorant, by driving the motor 333 to rotate, the worm 332 is driven to rotate, and the worm gear 331 is toggled to rotate, so that the rotating shaft 31 can be driven to rotate, and then multiple stirring blades 32 can stir the wastewater in the deodorization reaction tank 1 in a circular motion, so that the wastewater and the deodorant are fully mixed;

[0032] A feeding assembly 4 for feeding the deodorant into the inner side of the deodorization reaction tank 1 from bottom to top or from top to bottom is installed on the stirring assembly 3. The feeding assembly 4 includes a first inner cavity 41 formed in the middle of the rotating shaft 31. A second inner cavity 42 is formed in the middle of the stirring blade 32. The first inner cavity 41 is communicated with the second inner cavity 42. A plurality of discharge ports 43 are equidistantly arranged on one side of the stirring blade 32. A sealing plate 44 is slidably installed on the outer wall of the stirring blade 32 close to the discharge port 43. Two limiting strips 5 are symmetrically fixed on the side of the stirring blade 32 close to the sealing plate 44. The sealing plate 44 is slidably connected between the two limiting strips 5. A plurality of communication grooves 45 are equidistantly arranged on the sealing plate 44. The communication grooves 45 cooperate with the discharge ports 43. A moving assembly 46 for driving the sealing plate 44 to slide to switch between the first state of opening the discharge port 43 and the second state of closing the discharge port 43 is fixed on the outer wall of the stirring blade 32. A feed pipe 47 is fixed on the top of the deodorization reaction tank 1, and the end of the feed pipe 47 is rotatably connected to the outer wall of the upper end of the rotating shaft 31 through a sealing bearing;

[0033] The deodorant is pumped into the feed pipe 47 by a power device such as a water pump, then enters the first inner cavity 41 on the rotating shaft 31, and then enters the second inner cavity 42. By controlling the sliding of the sealing plate 44 through the moving component 46, when the sealing plate 44 slides to make the communication groove 45 face the discharge port 43, the deodorant enters the inside of the deodorization reaction tank 1 through the discharge port 43 and the communication groove 45;

[0034] For the two groups of stirring blades 32, the moving components 46 on the stirring blades 32 are controlled to work in the order from bottom to top. When the rotating shaft 31 rotates, first, the discharge port 43 on the stirring blade 32 at the lowest position in the two groups of stirring blades 32 is opened. At this time, the deodorant can enter the wastewater at the lower end in the deodorization reaction tank 1, and the discharge ports 43 on the remaining stirring blades 32 are in the second state blocked by the sealing plates 44 thereon. Subsequently, the discharge port 43 on the stirring blade 32 at the lowest position in the two groups of stirring blades 32 is closed, and the discharge port 43 on the second-lowest stirring blade 32 counted from bottom to top in the two groups of stirring blades 32 is opened, and the discharge ports 43 of the remaining stirring blades 32 are closed. The deodorant enters the wastewater in the lower part of the deodorization reaction tank 1. In this way, the input work of the deodorant is continuously carried out, so that the deodorant can be evenly input into the wastewater at each layer position in the deodorization reaction tank 1 from bottom to top, improving the efficiency of uniform mixing of the wastewater and the deodorant;

[0035] When the moving components 46 on the stirring are controlled to work in the order from top to bottom, the input work is opposite to the above. First, the discharge port 43 of the uppermost stirring blade 32 is opened, and finally the discharge port 43 of the lowermost stirring blade 32 is opened;

[0036] The moving component 46 includes a spring piece 461 fixed at one end of the outer wall of the stirring blade 32 close to the rotating shaft 31. The end of the spring piece 461 away from the rotating shaft 31 is fixed to the outer wall of the sealing plate 44. A roller 462 is rotatably connected to the end of the sealing plate 44 away from the spring piece 461. The roller 462 abuts against the inner wall of the deodorization reaction tank 1. Two groups of driving arc-shaped blocks 463 are symmetrically fixed on the inner wall of the deodorization reaction tank 1 in a central symmetry manner. Each group of driving arc-shaped blocks 463 is distributed in a stepped manner from top to bottom on the inner side of the deodorization reaction tank 1. The driving arc-shaped blocks 463 cooperate with the rollers 462;

[0037] The work of the moving component 46 is mechanically linked to the rotation of the rotating shaft 31. When the rotating shaft 31 rotates, the roller 462 rolls along the inner wall of the deodorization reaction tank 1 until it reaches the driving arc-shaped block 463 and is pushed open by the driving arc-shaped block 463, pushing the sealing plate 44 to slide and compress the spring piece 461. The sliding of the sealing plate 44 makes the communication groove 45 face the discharge port 43 for the input work of the deodorant;

[0038] The two sets of driving arc-shaped blocks 463 distributed in a stepped manner can enable a plurality of longitudinally distributed sealing plates 44 to slide open the discharge port 43 in sequence when the rotating shaft 31 rotates. Specifically, whether the deodorant is put into the deodorization reaction tank 1 in a top-down order or a bottom-up order can be achieved by controlling the forward and reverse rotation of the motor 333;

[0039] In summary, the present application can achieve the effect of uniformly putting the deodorant into the deodorization reaction tank 1 from top to bottom or from bottom to top, enabling the deodorant to be quickly distributed in the wastewater at each layer position in the deodorization reaction tank 1, reducing the mixing time of the deodorant and the wastewater, and improving the efficiency of uniform mixing of the deodorant and the wastewater.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
