Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of sewage treatment, and particularly relates to a microbial fermentation equipment for sewage treatment. BACKGROUND

[0002] With the acceleration of industrialization and the continuous growth of urban population, the problem of sewage treatment has become increasingly prominent. In the current technology, the biological fillings in the biological pool cultivate microorganisms, which is an indispensable part of sewage treatment. By placing fillings in the biochemical pool, the microorganisms attached thereto can convert organic matter, nitrogen, phosphorus and other pollutants in the sewage into inorganic substances in the fermentation metabolism process. In recent years, due to its high efficiency and low cost, biological filling technology has been widely used in the field of sewage treatment. Biological fillings mainly include soft fillings, semi-soft fillings and combined fillings. However, in practical application, the existing biological fillings still face some problems:

[0003] 1. Semi-soft fillings, also known as "snowflake" fillings, are mainly made of PP and PE and are formed by an injection molding machine. They decompose pollutants by being stirred with sewage in the biochemical pool. However, collisions between semi-soft fillings are prone to occur, which not only causes the falling of aged microorganisms, but also causes the shedding of unaged microorganisms, thereby affecting the efficiency of sewage treatment. Therefore, although the ring-shaped fillings improve the efficiency of sewage treatment to some extent, the efficiency still needs to be further improved.

[0004] 2. Soft fillings (composed of a plurality of filamentous fillings) and semi-soft fillings (composed of soft fillings and semi-soft fillings) usually need to be pulled and fixed by a central rope. Once the central rope is broken, the sewage in the biochemical pool must be emptied for replacement, which makes the maintenance process not only cumbersome but also time-consuming. In addition, during the installation and use of soft or semi-soft fillings, the filamentous fillings are prone to breakage. After the breakage of the filamentous fillings of the existing soft fillings and semi-soft fillings, the broken filamentous fillings enter the subsequent sewage treatment link with the sewage, and it is difficult for workers to judge the wear state of the fillings, and at the same time, the area of microorganism attachment is reduced, resulting in a decrease in the sewage treatment efficiency of the biochemical pool.

[0050] A plurality of driving units 30, a plurality of driving units 30 are arranged in the inside of the pool body 10, and the driving unit 30 is connected with the combined filler assembly 12, the driving unit 30 can drive the combined filler assembly 12 to move;

[0051] A plurality of limiting assemblies 40, a plurality of limiting assemblies 40 are arranged between the combined filler assembly 12 and the driving unit 30, the plurality of limiting assemblies 40 correspond one by one with the plurality of combined filler assemblies 12, and the limiting assembly 40 can fix the combined filler assembly 12;

[0052] Wherein, the guide cavity 26 is formed between the outer ring 21 and the inner ring 22, after the filament filler inside the bundle filler 23 breaks, the hollow ball 24 floats upward along the guide cavity 26.

[0053] It should be noted that the inside of the hollow ball 24 is provided with a through hole, and the bundle filler 23 penetrates the inside of the through hole.

[0054] In this embodiment, oxygen is inputted into the inside of the biochemical tank through the aeration assembly 11, and microorganisms in the biochemical tank are allowed to ferment and grow according to the existing microbial fermentation method. After the microorganisms form a film on the surface of the combined filler assembly 12, sewage is inputted into the inside of the tank body 10 through the water inlet pipe, and the organic matter, nitrogen, phosphorus and other pollutants in the sewage are converted into inorganic substances by the microorganisms. During installation or sewage treatment, if the filamentous filler in the bundle-shaped filler 23 is broken, the broken filamentous filler will enter the subsequent process with the sewage. At the same time, the bundle-shaped filler 23 after the filamentous filler is broken can no longer limit the hollow ball 24, and the hollow ball 24 floats upward along the guide cavity 26 and gathers in the inside of the gathering bottle 13. The number of the hollow balls 24 gathered in the inside of the gathering bottle 13 can quickly determine the loss state of the filler unit 20 in the combined filler assembly 12.

[0055] Secondly, in a preferred embodiment, the radius of the outer ring 21 is denoted as R1, the radius of the inner ring 22 is denoted as R2, and the diameter of the hollow ball 24 is denoted as D, and D < R1-R2.

[0056] In this embodiment, through the above-mentioned arrangement, after the filamentous filler in the bundle-shaped filler 23 is broken, the hollow ball 24 can smoothly float upward along the inside of the guide cavity 26 and gather in the inside of the gathering bottle 13, avoiding being stuck by the outer ring 21 and the inner ring 22.

[0057] Thirdly, please refer to Figure 4 , the end of the bundle-shaped filler 23 connected with the inner ring 22 is in a cylindrical shape, and the end of the bundle-shaped filler 23 away from the inner ring 22 is in a loose state.

[0058] Here, in order to make the drawings simple and clear, the bundle-shaped filler 23 in the drawings is in a block structure, and in actual application, the bundle-shaped filler 23 is in a loose filamentous state.

[0059] In this embodiment, the loose end of the bundle-shaped filler 23 extends through the inside of the avoidance slot 25 to the outside of the outer ring 21, which can simulate the shape of natural water grass, has the advantages of large specific surface area, high utilization rate, variable void and no blockage, etc.

[0060] Secondly, please refer to Figures 5 to 7 , the inside of the outer ring 21 is fixed with a plurality of T-shaped limiting rods 27, the sidewall of the inner ring 22 is provided with a plurality of guide grooves 28, the plurality of T-shaped limiting rods 27 and the plurality of guide grooves 28 are one-to-one corresponding, and the corresponding T-shaped limiting rod 27 and the guide groove 28 are slidably connected through the gap fit mode.

[0061] In this embodiment, through the above scheme, in the process of the sewage overturning, the gap between the T-shaped limiting rod 27 and the guide groove 28 matches the small amplitude shaking of the inner ring 22 inside the outer ring 21. Through the shaking of the inner ring 22, the microorganisms attached to the surface of the inner ring 22 can quickly fall off, and then new microorganisms can be attached to the surface of the inner ring 22, thereby ensuring the processing efficiency of the microorganisms on the surface of the inner ring 22 to the sewage.

[0062] Please refer again to Figure 6 and Figure 7 As shown, the upper end of the outer ring 21 outside is provided with external threads, and the lower end inside the outer ring 21 is provided with internal threads. In the same combined filler assembly 12, the outer rings 21 inside the adjacent two filler units 20 are threadedly connected through the cooperation of the external threads and the internal threads.

[0063] In this embodiment, in order to better describe the working state of the device, the filler unit 20 with large loss is marked as A, the filler unit 20 located at the upper end of A is marked as B, and the filler unit 20 located at the lower end of A is marked as C. When A needs to be replaced, the thread connection between the outer ring 21 in A and the outer ring 21 in B is released, and then the thread connection between the outer ring 21 in A and the outer ring 21 in C is released. A can be removed from the combined filler assembly 12, and then the outer ring 21 in the new filler unit 20 is threadedly connected with the outer ring 21 in B and the outer ring 21 in C in sequence, so that the replacement of the filler unit 20 can be completed.

[0064] Please refer again to Figure 3 and Figure 9 As shown, in the combined filler assembly 12, the outer ring 21 located at the uppermost end is threadedly connected with the collection bottle 13, and a plurality of air holes 14 are uniformly provided at the upper end of the outer side of the collection bottle 13.

[0065] It should be noted that in this embodiment, the lower end of the air hole 14 is cylindrical, the upper end of the air hole 14 is spherical, and during the sewage treatment process, the air hole 14 is located at the upper end of the liquid level of the sewage.

[0066] Further, in this embodiment, the color of the surface of the hollow ball 24 is preferably a color that can be easily distinguished in sewage, such as yellow, red or other colors that can be easily distinguished, so as to be easily distinguished by the staff.

[0067] In this embodiment, during the sewage treatment process, the arrangement of the air hole 14 can ensure that the water level inside the collection bottle 13 and the water level inside the pool body 10 remain consistent, which is convenient for the staff to observe the hollow ball 24 inside the collection bottle 13.

[0068] In a preferred embodiment, the material of the collection bottle 13 is transparent.

[0069] In this embodiment, the transparent material of the collecting bottle 13 enables the staff to observe the inside of the collecting bottle 13, and then determine the wear degree of the filler unit 20 according to the number of the hollow balls 24.

[0070] Please refer to Figure 10 and Figure 11 As shown in the figure, the driving unit 30 comprises four flange seats 31, two shaft rods 32, two first belt pulleys 33, two second belt pulleys 34, a first transmission belt 35, a second transmission belt 36 and a hand wheel 37. The four flange seats 31 are symmetrically fixed to the two sides inside the pool body 10. The two shaft rods 32 are respectively rotatably connected between the two flange seats 31 on the same side. The two first belt pulleys 33 are respectively fixed to the lower ends of the outer sides of the two shaft rods 32. The two second belt pulleys 34 are respectively fixed to the upper ends of the outer sides of the two shaft rods 32. The first transmission belt 35 is assembled to the outer sides of the two first belt pulleys 33. The second transmission belt 36 is assembled to the outer sides of the two second belt pulleys 34. The hand wheel 37 is fixed to the upper end of the outer side of one of the shaft rods 32 and located at the upper end of the pool body 10. The first transmission belt 35 and the limiting assembly 40 and the second transmission belt 36 and the limiting assembly 40 are connected to each other.

[0071] In this embodiment, when there are more hollow balls 24 collected in any of the collecting bottles 13, it indicates that the filler unit 20 in the corresponding combined filler assembly 12 has a large wear degree and needs to be replaced. By rotating the hand wheel 37, the shaft rod 32 is driven to rotate. Since the shaft rod 32 and the first belt pulley 33 and the shaft rod 32 and the second belt pulley 34 are fixedly connected, the shaft rod 32 drives the first belt pulley 33 and the second belt pulley 34 to rotate, and then drives the first transmission belt 35 and the second transmission belt 36 to rotate through the first belt pulley 33 and the second belt pulley 34. The limiting assembly 40 and the combined filler assembly 12 are synchronously moved through the first transmission belt 35 and the second transmission belt 36, so that the combined filler assembly 12 with a large wear degree moves towards the edge of the pool body 10. Until the staff can replace the combined filler assembly 12 at the edge of the pool body 10. The driving unit 30 enables the staff to conveniently replace the filler unit 20 with a large wear degree without emptying the sewage inside the pool body 10, greatly simplifies the steps of replacing the filler unit 20, and improves the maintenance efficiency.

[0074] In this embodiment, when replacing the filler unit 20, the fastening bolt between the first arc-shaped clamping ring 42 and the second arc-shaped clamping ring 43 is rotated to release the limiting of the clamp for the collecting bottle 13, the combined filler assembly 12 to be replaced is taken out, and the breakage of the bundle-shaped filler 23 in the filler unit 20 is checked one by one, the filler unit 20 with greater loss is replaced, after replacement is completed, the lower end of the combined filler assembly 12 is inserted into the inside of the positioning hole 46, and the clamp again forms limiting for the collecting bottle 13, so that the replacement of the filler unit 20 is completed.
