Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment and anaerobic fermentation technology, and in particular to a device for unclogging the overflow port of an anaerobic tank. Background Technology

[0002] Anaerobic digesters are the core process equipment in food waste treatment plants, and their stable operation directly affects the plant's overall capacity and efficiency. The overflow port is a key component on the anaerobic digester used to maintain a constant liquid level, ensure continuous discharge, and prevent tank overload. Its unobstructed flow is crucial to the hydraulic retention time and operational stability of the anaerobic digestion process.

[0003] Because food waste has a complex composition, containing large amounts of fibers, grease, bone shells, and other easily deposited substances, these materials readily accumulate and harden inside the overflow pipe during anaerobic digester operation, forming solid blockages. In existing technologies, the overflow port is typically a U-shaped groove welded to the tank wall. Its unique structure makes it impossible for operators to directly access and clear the blockage from the outside once an internal blockage occurs. Traditional unblocking methods (such as external poking) are completely ineffective, and the only solution is often to stop operation, empty the tank, and manually clean it. This process is not only time-consuming, labor-intensive, and costly, but also poses risks associated with working in confined spaces and can lead to prolonged shutdowns and significant economic losses.

[0004] Therefore, there is an urgent need in this field for a specialized tool that can efficiently, safely, and non-invasively unclog the blockage point inside the overflow port from outside the anaerobic tank. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] The following is combined Figures 1-4This invention describes an apparatus for unclogging the overflow port of an anaerobic tank according to an embodiment of the present invention.

[0022] like Figure 1-3 As shown, this utility model embodiment provides a device for unblocking the overflow port of an anaerobic tank. The overflow port 11 is provided on the side wall of the anaerobic tank 1; the inner baffle 12 is provided on the inner wall of the anaerobic tank 1; and the outer baffle 13 is provided on the outer wall of the anaerobic tank 1, forming a U-shaped overflow channel with the inner baffle 12. The unblocking pipe 2 has one end bent to allow it to extend into the anaerobic tank 1 along the overflow channel; the connecting pipe 3 has one end connected to the end of the unblocking pipe 2 away from the overflow channel; and the pump body 4 is connected to the end of the connecting pipe 3 away from the unblocking pipe 2.

[0023] It should be understood that the anaerobic digester 1 is the core process equipment for treating kitchen waste. An overflow port 11 is provided on the top side wall of the anaerobic digester 1 to maintain a constant liquid level, ensure continuous discharge, and prevent tank pressure overload. Therefore, the unobstructed flow of the overflow port 11 is crucial to the hydraulic retention time and operational stability of the anaerobic digestion process. In this embodiment, the end of the unblocking pipe 2 is bent to fit the structure of the overflow channel. The unblocking pipe 2 extends into the anaerobic digester 1 through the overflow port 11. The pump body 4 provides high-pressure fluid, and the impact force provided by the high-pressure fluid can accurately and effectively break up blockages, achieving rapid unblocking of the overflow port 11. There is no need to empty the tank, ensuring continuous production. Unblocking operations can be performed by a single person outside the tank, eliminating the need to enter the tank and avoiding the safety risks associated with personnel entering the tank.

[0024] In some possible implementations, both the inner baffle 12 and the outer baffle 13 are welded and fixed to the anaerobic tank 1; the unblocking pipe 2 is made of metal, such as stainless steel, and the connecting pipe 3 is made of flexible material, such as plastic or rubber; the bend of the unblocking pipe 2 can be U-shaped to fit the U-shaped overflow channel, and the main body of the unblocking pipe 2 is straight, so the unblocking pipe 2 is J-shaped, which allows the unblocking pipe 2 to naturally fit the inner wall of the overflow channel and bend inward until its outlet is aligned with the blockage inside the anaerobic tank 1. This allows the high-pressure water flow to be accurately guided to the inner force point of the blockage, and the shearing, impact and wedging action of the high-pressure water jet can break up the slab from the root, making the unblocking efficiency much higher than that of external operation.

[0025] like Figure 4 As shown, according to an embodiment of the present invention, a device for unblocking the overflow port of an anaerobic tank is provided. The unblocking pipe 2 includes: a first pipe body 21, which is bent and located in the overflow channel, with its two ends located on the inner and outer sides of the anaerobic tank 1, respectively; and a second pipe body 22, one end of which is connected to the end of the first pipe body 21 located on the outer side of the anaerobic tank 1, and the other end of which is connected to a connecting pipe 3.

[0026] It should be understood that the drain pipe 2 can be integrally formed, or it can be formed by splicing the first pipe body 21 and the second pipe body 22 as in the above embodiment. The integrally formed drain pipe 2 has good integrity and does not require on-site installation, and can be put into use directly. However, its disadvantage is that it is less flexible. When encountering overflow channels of different depths and widths, it may not be able to be accurately adapted. On this basis, the drain pipe 2 with separate components has higher flexibility. It can replace the first pipe body 21 with different models according to the size of different overflow channels, and use different models of first pipe body 21 to connect with the second pipe body 22, which can improve the adaptability and flexibility of the drain pipe 2.

[0027] In some possible implementations, the first tube 21 and the second tube 22 are detachably connected by threads.

[0028] like Figure 4 As shown, according to an embodiment of the present invention, a device for unblocking the overflow port of an anaerobic tank is provided. The first pipe body 21 includes: a first bent section 211, one end of which is connected to a second pipe body 22, and the other end of which extends through the overflow port 11 toward the inner side of the anaerobic tank 1; and a second bent section 212, one end of which is connected to the end of the first bent section 211 away from the second pipe body 22, and the other end of which extends along the inner wall of the anaerobic tank 1.

[0029] It should be understood that, based on the separate configuration of the first pipe body 21 and the second pipe body 22, the first pipe body 21 is further divided into a first bending section 211 and a second bending section 212. For different lengths of the vertical and horizontal sections of the overflow channel, different models (length or curvature) of the first bending section 211 or the second bending section 212 can be selected for connection. Based on the aforementioned embodiments, the goal of achieving higher precision and adaptability is achieved, thereby improving the dredging efficiency and the user experience of the operators.

[0030] According to an embodiment of the present invention, a device for unblocking the overflow port of an anaerobic tank is provided, wherein the first bending section 211 and the second bending section 212 are detachably connected, and the second bending section 212 and the second pipe body 22 are detachably connected.

[0031] In some possible implementations, the first bend segment 211 and the second bend segment 212 are detachably connected by threads, and the second bend segment 212 and the second pipe body 22 are detachably connected by threads.

[0032] According to an embodiment of the present invention, a device for unblocking the overflow port of an anaerobic tank is provided, wherein the second pipe body 22 is composed of multiple detachable unit pipes connected together.

[0033] In some possible implementations, the multi-segment unit pipes of the second pipe body 22 are detachably connected by threads.

[0034] It should be understood that the second tube 22 can be a one-piece molded tube with good integrity and stability. However, due to differences in the height and usage habits of operators, the required length of the second tube 22 will also vary. In this case, the second tube 22 can be designed as a multi-segment or expandable type. For example, the second tube 22 can be designed as a multi-segment metal tube with threads at both ends. Operators can choose to use only one segment of the metal tube or connect multiple segments together. This takes into account the operating habits of operators, improves the user experience and the efficiency of the device.

[0035] like Figure 4 As shown, a device for unblocking the overflow port of an anaerobic tank according to an embodiment of the present invention further includes: a pressurizing nozzle 5, which is detachably disposed at one end of the first tube 21 located inside the anaerobic tank 1.

[0036] It should be understood that, in order to further enhance the water pressure at the end of the first pipe body 21 and improve the efficiency and effect of breaking up blockages, a pressure nozzle 5 can also be installed at the end of the first pipe body 21. Any commercially available pressure nozzle 5 can be used.

[0037] like Figure 4 As shown, a device for unblocking the overflow port of an anaerobic tank according to an embodiment of the present invention further includes: a valve 6, which is disposed at one end of the second pipe body 22 near the connecting pipe 3.

[0038] It should be understood that valve 6 is installed in the second pipe body 22 and can regulate water flow rate, as well as water flow velocity and water pressure. Valve 6 can be a common ball valve or a gate valve.

[0039] like Figure 3 As shown, a device for unclogging the overflow port of an anaerobic tank according to an embodiment of the present invention further includes: a connector 7, which is disposed at the connection between the connecting pipe 3 and the unclogging pipe 2.

[0040] In some possible implementations, the connector 7 can be a union to connect the flexible connecting pipe 3 to the rigid drain pipe 2; or a stainless steel clamp can be used to secure the connecting pipe 3 to the drain pipe 2.

[0041] According to an embodiment of the present invention, a device for unblocking the overflow port of an anaerobic tank further includes: a gripping part 8, disposed on the unblocking pipe 2, suitable for the operator to grip.

[0042] In some possible implementations, the grip 8 is sleeved onto the drain pipe 2 and bonded to it; further, the grip 8 can be made of materials such as plastic or rubber, and the grip 8 can be designed in an ergonomic curved shape, or designed in the shape of a handle, so as to facilitate the operator's grip and prevent the operator from slipping out of their hand due to excessive water pressure during operation, thus avoiding danger; further, the surface of the grip 8 can also be provided with regular or irregular bumps or textures to further enhance friction and improve the safety factor.

[0043] It should be understood that for the integral type of drain pipe 2, the grip part 8 can be set in the middle of the drain pipe 2, which conforms to the operating habits of most operators; for the split type of drain pipe 2, the grip part 8 can be set on one of the unit pipes, as long as the unit pipe is in an appropriate position for easy gripping during use.

[0044] like Figure 3 As shown, a device for unclogging the overflow port of an anaerobic tank according to an embodiment of the present invention further includes: a moving mechanism 9, which is disposed on the ground, and a pump body 4 is disposed on the moving mechanism 9.

[0045] In some possible implementations, the mobile mechanism 9 can be a vacuum truck, in which case the pump body 4 is a high-pressure water pump that is built into the vacuum truck; the mobile mechanism 9 can also be other vehicle carriers, or even mobile flatbed trucks, as long as they can carry the high-pressure water pump and power it.

[0046] like Figure 3 As shown in a specific embodiment of this utility model, the device for unblocking the overflow port of an anaerobic tank provided in this embodiment operates as follows: The operator inserts the unblocking pipe 2 into the external port of the overflow outlet 11. Due to the J-shaped design of the unblocking pipe 2, it can naturally conform to the inner wall of the overflow channel and bend inward until its outlet is aligned with the blockage on the inside. Then, one end of the connecting pipe 3 is connected to the unblocking pipe 2 through the connector 7, and the other end of the connecting pipe 3 is connected to the external high-pressure water pump. After the high-pressure water pump is turned on, the high-pressure water flows through the connecting pipe 3, the second pipe body 22 and the first pipe body 21 in sequence, and finally shoots out at high speed from the outlet of the first pipe body 21, directly impacting the inner surface of the blockage. During the unblocking process, the operator can slightly adjust the insertion angle and depth of the first pipe body 21 until the blockage is completely broken up and dispersed, restoring the unobstructed flow of the overflow outlet 11.

[0047] The application of the device provided in this embodiment can ensure the long-term stable operation of the core equipment, the anaerobic tank 1, effectively guaranteeing the continuous production and economic benefits of the entire food waste treatment plant. In addition, the device has a simple structure, low manufacturing cost, and can adapt to overflow ports 11 with different pipe diameters and heights; it only needs to be connected to a common high-pressure water source on site to operate, resulting in extremely low operation and maintenance costs and making it easy to promote and popularize on a large scale in the industry.

The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
