Description

Technical Field

[0001] This application relates to the field of enamel steel plate assembly technology, and more specifically, to a modular enamel steel plate assembly structure. Background Technology

[0002] Enameled prefabricated tanks, as efficient and flexible storage and reaction containers, have demonstrated significant application value in various industrial fields, especially in environmental protection areas such as wastewater treatment and biogas fermentation. These tanks, with their unique ease of installation, short construction period, excellent corrosion resistance, and high scalability and mobility, have become the preferred alternative to traditional concrete or steel structure tanks. The enamel coating not only enhances the tank's resistance to chemical corrosion but also improves its overall durability and service life, adapting to the demands of complex and ever-changing working environments.

[0003] However, despite the numerous advantages of enamel-lined assembled tanks, their sealing performance has always been a key factor restricting their widespread application and long-term stable operation. The challenges of sealing design are particularly pronounced at critical joints in the tank structure, such as the junction between the bottom and sidewalls. These areas are subjected to multiple factors, including internal medium pressure, changes in the external environment, and installation stress, significantly increasing the risk of seal failure. Poor sealing not only leads to leakage of gas or liquid inside the tank, directly affecting processing efficiency and quality, but can also pollute the surrounding environment, contradicting the original design intent of environmental protection facilities. Existing tanks fall into two categories: one is a single-piece tank, which is inconvenient for installing agitators and requires deep penetration into the tank for operation; the other is a modular design, but lacks sufficient airtightness and is prone to leakage.

[0004] Therefore, this application proposes a modular enamel steel plate assembly structure, which solves the technical problems of insufficient airtightness and poor stirring effect of spliced ​​structures.

[0005] Therefore, developing a new sealing structure that can effectively guarantee long-term sealing performance while being easy to install, maintain, and expand is of great significance for improving the overall performance of enamel-lined assembled tanks, expanding their application areas, and ensuring the safe and efficient operation of environmental protection facilities. Utility Model Content

[0006] Based on the above problems, this application proposes a modular enamel steel plate assembly structure to solve technical problems such as poor assembly and sealing effect and complex installation.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A modular enamel steel plate assembly structure includes assembly plates. One of the assembly plates on one side of a set of assembly plates is provided with a notch, and the other assembly plate is provided with a protruding corner adapted to the notch. At the junction of the two assembly plates, one assembly plate is provided with a raised sealing strip, and the other assembly plate is provided with a sealing groove adapted to the sealing strip. Each assembly plate has an outer edge on its upper and lower sides to enhance sealing, with a sealing interlayer in the middle of the outer edge. Mounting holes are provided around the perimeter of each assembly plate. An agitator is installed inside the structure.

[0009] In one specific implementation, the sealing interlayer consists of two layers, the sealing interlayer is corrugated, and the two layers of the sealing interlayer engage with each other.

[0010] In one specific implementation scheme, the outer wall of the structure is provided with a feed inlet and a slag discharge outlet, and the feed inlet and the slag discharge outlet are connected to the interior of the structure.

[0011] In one specific implementation scheme, the structure is equipped with a positive and negative pressure protector and an overflow device, and a biogas discharge port is provided at the top of the structure, which is connected to the interior of the structure.

[0012] In one specific implementation, a stirrer is provided inside the structure, and the stirrer is mounted on the side of the structure via a bracket.

[0013] In one specific implementation, at least one agitator is provided. The agitator includes a mounting base mounted on the support, a first motor mounted on the mounting base, a support frame, a mounting bracket mounted on the support frame, the mounting bracket being hinged to the support frame, a second motor mounted on the mounting bracket, the second motor being hinged to the mounting bracket, the power output end of the first motor being connected to the second motor via a connecting rod, the two ends of the connecting rod being rotatably connected to the first motor and the second motor, and agitator blades being mounted on the power output end of the second motor.

[0014] The positive effects of this utility model are:

[0015] By designing a structure with interlocking notched and convex corners on the assembly panels, and adapting the raised sealing strips to the sealing grooves, the connection tightness and sealing performance between the assembly panels are greatly enhanced. This design not only simplifies the installation process, making assembly more convenient, but also ensures that the assembly structure maintains a good sealing state when subjected to multiple factors such as internal medium pressure, external environmental changes, and installation stress, effectively preventing gas or liquid leakage.

[0016] The sealing interlayer further enhances the sealing performance. The sealing interlayer adopts a corrugated design and has two interlocking layers. This structure not only increases the thickness and strength of the sealing layer, but also enhances the elasticity and adaptability of the sealing interlayer through the corrugated interlocking design, enabling it to better adapt to deformation and stress changes under different working conditions, thereby maintaining a stable sealing effect over a long period of time.

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

[0030] Example 1

[0031] like Figure 1-9 As shown, a modular enamel steel plate assembly structure includes assembly plates 1, each assembly plate 1 having mounting holes 7 around its perimeter. This facilitates the connection and fixing of the assembly plates 1, ensuring the stability and reliability of the assembly. The design of the mounting holes 7 makes the assembly process simpler and faster, reducing installation time and costs.

[0032] One of the assembly plates 1 on one side of the set of assembly plates 1 is provided with a notch 2, and the other assembly plate 1 is provided with a protruding corner 3 that matches the notch 2.

[0033] At the junction of the two assembly plates 1, one of the assembly plates 1 is provided with a raised sealing strip 4, and the other assembly plate 1 is provided with a sealing groove 5 that matches the sealing strip 4; each assembly plate 1 is provided with an outer edge on both the upper and lower sides to enhance the sealing performance, and a sealing interlayer 6 is provided in the middle of the outer edge. The sealing interlayer 6 is provided in two layers and is wavy, with the two layers of sealing interlayer 6 interlocking.

[0034] Each assembled panel 1 has outer edges on both its top and bottom sides to enhance sealing. These edges increase the contact area at the joints, further improving the sealing effect. The sealing interlayer 6 is wavy, with two interlocking layers. This design increases the contact area of ​​the sealing interlayer 6, improving the sealing effect. The wavy design also absorbs and disperses stress to a certain extent, enhancing the stability of the structure.

[0035] The combination of notch 2 and convex corner 3 ensures a tight fit between the assembled plates 1, reducing gaps at the joints and thus improving sealing performance. This design effectively prevents gas or liquid leakage, ensuring the tank's airtightness. Simultaneously, the combination of notch 2 and convex corner 3 reduces the shear stress on the sealing bolts when using the mounting hole 7 (see...). Figure 9 ).

[0036] The combination of physical structures further enhances the sealing effect at the joints. The design of the sealing strip 4 and the sealing groove 5 effectively prevents gas or liquid from leaking from the joints, improving the overall sealing performance of the tank.

[0037] The outer wall of the structure is provided with a feed inlet 8 and a slag discharge outlet 9, which are connected to the interior of the structure. The structure is provided with a positive and negative pressure protector 10 and an overflow device 11, and a biogas discharge outlet 12 is provided at the top of the structure, which is connected to the interior of the structure.

[0038] Example 2

[0039] The difference between this embodiment and the above embodiment is that the stirrer is described in more detail. The stirrer is installed inside the overall structure composed of multiple assembled plates 1. The stirrer is installed on the side of the structure by a bracket 13.

[0040] At least one agitator is provided. Each agitator includes a mounting base 14 mounted on the support 13, a first motor 15 mounted on the mounting base 14, a support frame 16, and a mounting bracket 17 mounted on the support frame 16. The mounting bracket 17 is hinged to the support frame 16. A second motor 18 is mounted on the mounting bracket 17 and is also hinged to the mounting bracket 17. The power output end of the first motor 15 is connected to the second motor 18 via a connecting rod 19. Both ends of the connecting rod 19 are rotatably connected to both the first motor 15 and the second motor 18. Agitator blades 20 are mounted on the power output end of the second motor 18. This design improves the mixing efficiency of the medium in the tank, ensuring better treatment results. The agitator design enables large-field mixing, improving mixing efficiency and ensuring uniform mixing of the medium in the tank, thus enhancing the treatment effect. Installing multiple independent agitators ensures better mixing quality and prevents poor mixing due to an oversized assembled structure.

[0041] Working principle

[0042] Assembly process:

[0043] The assembly plates 1 are secured together using the mounting holes 7 around their perimeter. The notched corners 2 and convex corners 3 between the assembly plates 1 ensure a tight fit at the joints, minimizing gaps. The sealing strips 4 and sealing grooves 5 at the joints of the assembly plates 1 further enhance the sealing effect. The outer edges on the upper and lower sides of the assembly plates 1 and the wavy sealing interlayer 6 further improve sealing performance, ensuring the overall sealing of the tank.

[0044] Operation process:

[0045] Material is fed into the tank through inlet 8 and processed inside. An agitator is mounted inside the structure via bracket 13. A first motor 15 and a second motor 18 drive the agitator blades 20, achieving large-field mixing and improving the mixing efficiency of the medium within the structure, ensuring effective treatment. The generated biogas is discharged through biogas outlet 12, ensuring stable pressure inside the tank. A positive and negative pressure protector 10 automatically regulates the tank pressure to prevent leakage and structural damage due to pressure changes. An overflow device 11 prevents liquid from overflowing, ensuring safe operation of the tank. The treated material is discharged through slag outlet 9, completing the entire treatment process.
