Description

TECHNICAL FIELD

[0001] The present application relates to the field of biochemistry, in particular to a biochemical filler protection structure and an aeration tank. BACKGROUND

[0002] The moving bed biofilm reactor (MBBR) process is a new type of wastewater treatment process. It combines the advantages of activated sludge method and biofilm method. It is widely used in urban wastewater treatment, industrial wastewater treatment and other fields. The moving bed biofilm reactor process can be used as an efficient and energy-saving treatment technology, and has good effect on the removal of some refractory organic matter in industrial wastewater treatment, such as papermaking wastewater and printing and dyeing wastewater treatment. The principle of moving bed biofilm reactor process is to add a certain amount of suspended filler to the aeration tank, and use the suspended filler as the growth carrier of microorganisms. When the wastewater flows through the filler continuously, the wastewater is purified through the action of microorganisms.

[0003] However, in the operation process of the traditional aeration tank, due to the flow direction of the wastewater and the movement characteristics of the filler, the filler is easy to accumulate at the drainage end, block the drainage pipeline, and affect the normal operation of the aeration tank. This not only needs to be cleaned regularly, but also the cleaning process is complex, which may affect the stability of the wastewater treatment system. CONTENT OF THE INVENTION

[0005] The first aspect of the present application provides a biochemical filler protection structure, which comprises:

[0006] The groove frame is located at the top end of the mesh grid, and the mesh grid is connected to the groove frame in a wrapped form. The space formed by the mesh grid and the groove frame is used for placing biochemical fillers. The pore size of the mesh grid is smaller than the outer diameter of the biochemical fillers.

[0007] Optionally, the bottom of the mesh grid is spaced apart and has a hole area and a bottom plate.

[0008] Optionally, the top of the groove frame is provided with a support on both sides, and the support is used for clamping the inner wall of the aeration tank.

[0016] The tank body is provided with an aeration pipe at the inner bottom, and the biochemical filler protection structure is arranged in the tank body and located above the aeration pipe.

[0017] From the above technical solutions, the present application has the following advantages:

[0018] The structure of the groove frame and the mesh provides a stable placement space for the biochemical fillers. By setting the mesh holes on the mesh to be smaller than the size of the fillers, the fillers are always placed in the area surrounded by the frame, which can effectively limit the biochemical fillers in a specific space, thereby avoiding the fillers from moving to the drain position to cause the blockage of the drain pipe. In the traditional aeration tank, the biochemical fillers are prone to accumulate and block the drain pipe at the drain end during operation. The biochemical protection structure of the present application avoids the blockage, and does not need to perform complex regular cleaning work, thereby reducing the interference on the sewage treatment system caused by cleaning the filler accumulation, improving the reliability and continuity of the operation of the entire sewage treatment system, and improving the treatment efficiency of the sewage.

[0029] The technical solutions in the present application will be described clearly and completely in the following with reference to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 , the present application provides a biochemical filler protection structure, comprising:

[0031] The groove frame 01 is connected to the mesh 02 in a wrapped manner, and the mesh 02 and the groove frame 01 cooperate to form a space for placing the biochemical filler. The mesh 02 has a pore size smaller than the outer diameter of the biochemical filler.

[0032] The groove frame 01 is located at the top of the mesh 02 and cooperates with the mesh 02 to provide a stable containing space for the biochemical filler. The groove frame 01 and the mesh 02 together ensure that the biochemical filler is uniformly distributed in the mesh 02. The mesh 02 has a pore size smaller than the outer diameter of the biochemical filler, and the biochemical filler is limited in the space formed by the groove frame 01 and the mesh 02, allowing gas to enter and exit the mesh 02 through the pores of the mesh 02, and preventing the biochemical filler from overflowing from the mesh 02.

[0033] The structure of the groove frame 01 and the mesh 02 provides a stable placement space for the biochemical filler. By setting the mesh hole on the mesh 02 to be smaller than the size of the filler, the filler is always in the area surrounded by the groove frame 01, which effectively limits the biochemical filler in a specific space, thereby avoiding the filler moving to the drain position and causing the drain pipe to be blocked. The traditional aeration tank is prone to accumulation of biochemical fillers at the drain end, which can block the drain pipe. The biochemical protection structure of the present application avoids the occurrence of blockage, does not need to perform complex regular cleaning work, reduces the interference caused by cleaning the filler accumulation on the sewage treatment system, and improves the reliability and continuity of the operation of the entire sewage treatment system and the treatment efficiency of the sewage.

[0034] In an optional embodiment, the mesh 02 bottom is spaced apart with a hole area and a bottom plate 06.

[0035] Please continue to refer to Figure 5 In this embodiment, the hole area and the bottom plate 06 are spaced apart at the bottom of the mesh 02. The hole area has a certain shape and size to allow gas to pass through. The bottom plate 06 provides structural support for the mesh 02, enhancing the overall stability of the mesh 02, and the bottom plate 06 can prevent the mesh 02 from deforming. When the aeration pipe 010 is running and continuously aerating, the gas passes through the hole area at the bottom of the mesh 02 from bottom to top, and under the action of aeration, a circulating flow is formed in the area corresponding to the hole area and the bottom plate 06. The circulating flow keeps the biochemical filler in motion in the space of the mesh 02, thereby ensuring that the biochemical filler and the sewage are in full contact and reaction, and improving the reaction efficiency.

[0036] In an optional embodiment, the groove frame 01 top is provided with a support 03 on both sides, and the support 03 is used to be clamped in the inner wall of the aeration tank.

[0037] In the embodiment, the groove frame 01 serves as the top part of the whole structure, providing support for the mesh grid 02 and ensuring the stability of the whole structure. The connection between the groove frame 01 and the mesh grid 02 is tight, preventing the biochemical filler from leaking during use and ensuring that the filler is in full contact with the sewage in the aeration tank.

[0038] The support 03 on both sides of the top of the groove frame 01 can be clamped to the inner wall of the aeration tank, accurately fixing the groove frame 01 and the mesh grid 02 structure at a specific position in the aeration tank, ensuring that the structure does not move during aeration. The support 03 is clamped to the inner wall of the aeration tank, greatly enhancing the stability of the whole structure in the aeration tank. The presence of the support 03 also enables the groove frame 01 and the mesh grid 02 structure to withstand the fluctuating external forces generated by the air flow from the operation of the aeration device, maintaining the integrity of the structure and ensuring the effectiveness of the biochemical filler during treatment.

[0039] In an alternative embodiment, the support 03 and the groove frame 01 are integrally formed.

[0040] In the embodiment, the support 03 and the groove frame 01 are integrally formed, and the monolithic structure can withstand greater external forces and is less likely to break or deform in the complex environment of the aeration tank. Integrally forming ensures the stability of the connection between the support 03 and the groove frame 01. When installed on the inner wall of the aeration tank, the support 03 can be more securely clamped to the inner wall of the aeration tank, preventing the entire structure from shifting or moving during use, thereby ensuring the effectiveness of the biochemical filler during treatment. The integrally forming process can accurately control the relative position and size of the support 03 and the groove frame 01. Since the structure is stably fixed in the aeration tank and cannot be moved arbitrarily by water flow and air flow, interference with the aeration device is avoided.

[0041] In an alternative embodiment, the support 03 and the inner wall of the aeration tank are connected by bolts 05.

[0042] In the embodiment, the support 03 and the inner wall of the aeration tank are connected by bolts 05, which provide strong connection force. By tightening the bolts 05, the support 03 is securely fixed to the inner wall of the aeration tank, ensuring the stability of the entire groove frame 01 and mesh grid 02 structure in the aeration tank. This secure connection can withstand various external forces such as water flow in the aeration tank, vibration generated by aeration, and the weight of the biochemical filler, preventing the structure from shifting, moving, or falling off during use.

[0043] The mounting process of the bolt 05 is relatively simple. The corresponding bolt holes are pre-set on the inner wall of the aeration tank and the support 03, and then the bolt 05 is passed through the hole and tightened. During the installation process, if it is necessary to adjust the position of the structure according to the actual situation, the bolt 05 can be loosened for fine adjustment, and then the bolt 05 is tightened to fix it.

[0044] In an optional embodiment, the side wall of the grid 02 is provided with a fixing structure 04 which is connected to the grid 02 by welding.

[0045] In this embodiment, the fixing structure 04 is located on the side wall of the grid 02, and its shape and size are specially designed according to the overall installation and fixing requirements of the grid 02 to ensure that the grid 02 can be stably fixed and prevent local stress from being too large to cause deformation or damage.

[0046] The fixing structure 04 is connected to the grid 02 by welding, and a firm whole is formed between the fixing structure 04 and the grid 02. When external force is applied, the welding point can effectively transfer stress to avoid loosening or separation between the fixing structure 04 and the grid 02.

[0047] In an optional embodiment, the fixing structure 04 and the grid 02 are both made of stainless steel material.

[0048] In this embodiment, stainless steel has high strength and hardness, and its strength can meet the requirement of bearing external force under different working conditions. When external force is applied, the stainless steel material will not easily deform or be damaged. At the same time, the hardness characteristics make the stainless steel surface have good wear resistance, which can maintain the shape and structural integrity of itself during contact or friction with other objects.

[0049] Specifically, the fixing structure 04 is two stainless steel pipes arranged in cross, which are welded on the side of the grid 02, so as to enhance the strength of the grid 02 and prevent the grid 02 from being cracked due to the expansion of the biochemical filler.

[0050] In an optional embodiment, the holes on the grid 02 are regular hexagons, and the surface of the bottom plate 06 is provided with a corrosion-resistant coating.

[0051] In this embodiment, the angle between adjacent sides of the regular hexagon is 120°, and this angle characteristic makes the force more evenly distributed around the hole when the grid 02 bears external force.

[0052] The surface of the bottom plate 06 is provided with a corrosion-resistant coating, and the surface of the corrosion-resistant coating is made of special corrosion-resistant material. The corrosion-resistant coating is uniformly covered on the surface of the bottom plate 06 by spraying, dipping or chemical plating process, so as to isolate the bottom plate 06 from corrosive medium and prevent the bottom plate 06 from rusting or being corroded.

[0053] In an alternative embodiment, the tank frame 01 and the mesh 02 are connected in a detachable manner.

[0054] In this embodiment, the tank frame 01 and the mesh 02 are equipped with specially designed connecting components to achieve detachable connection. When the connecting components are connected by the card slot 08 and the card block 07, the inner wall of the tank frame 01 is provided with the card slot 08, and the shape and size of the card slot 08 are accurately matched with the card block 07 on the edge of the mesh 02. The card slot 08 has a certain depth and width, which can firmly accommodate the card block 07, and can provide stable connection after being carded in. The inner wall of the card slot 08 has a certain roughness or is provided with anti-skid lines, which can increase the friction between the card block 07 and the card slot 08 when the card block 07 is carded into the card slot 08, preventing the card block 07 from easily sliding out when subjected to external force.

[0055] The detachable connection makes it very easy to maintain, replace and clean the equipment. By using detachable connection, parts can be easily replaced, and the equipment can be regularly maintained, thereby prolonging its service life.

[0056] Please refer to Figure 4 , another aspect of the present application provides an aeration tank, comprising:

[0057] The tank body 09 is provided with an aeration pipe 010 on the inner bottom, and the biochemical filler protection structure is arranged in the tank body 09 and located above the aeration pipe.

[0058] The aeration pipe 010 is installed on the bottom of the tank body by a special fixing device, which is composed of a series of pipelines, and the pipelines are uniformly distributed with aeration holes. The material of the aeration pipe 010 is usually corrosion-resistant plastic or metal material to adapt to the sewage environment and prevent rust or corrosion. The aeration pipe 010 continuously outputs gas to promote the reaction of the biochemical filler, and the biochemical filler protection structure prevents the biochemical filler from blocking the drain pipe of the aeration tank.

[0059] It should be noted that the above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
