They are assembled on-site from custom-manufactured enamel-lined steel plates using self-locking bolts, with gaps sealed with sealant to ensure airtightness and stability. They possess numerous significant advantages: simple and quick installation, significantly shortening the construction period; excellent corrosion resistance, with internal and external enamel coatings resisting strong acids, alkalis, and high temperatures; stable and reliable quality, with standardized production guaranteeing product quality; flexibility for expansion and relocation; an attractive appearance; and relatively low cost. For these reasons, they are widely used in various fields, including wastewater treatment plants, biogas digesters and gas holders, softened water tanks in power plants, and storage of industrial water, edible oil, and grains, providing efficient and reliable storage solutions for various industries.
[0003] Existing enamel-lined assembled tanks require additional reinforcement structures, as their structural strength is insufficient and their stability is low. Utility Model Content
[0004] The purpose of this invention is to provide a stable, multi-layered enamel-coated tank structure that maintains high structural strength and stability without the need for additional reinforcement.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A stable, multi-layered enamel-lined assembled tank structure includes an assembled tank body, which is assembled from multiple enamel-lined steel plates. A connecting frame is integrally connected to the edge of each enamel-lined steel plate. The connecting frame is rectangular and has multiple through holes on its outer surface. Multiple connecting blocks are fixedly connected to the inner walls of adjacent sides of the connecting frame. A threaded hole is provided in the middle of each connecting block, and the threaded hole corresponds to the position of the through hole. Adjacent enamel-lined steel plates are fixedly connected by connecting bolts, which pass through the through holes and threaded holes.
[0007] By adopting the above technical solution, assembly can be convenient, while the overall structural strength and support are stable.
[0008] Furthermore, a rubber gasket is fitted and wrapped around the outer surface of the connecting frame, and the rubber gasket is bonded to the connecting frame with adhesive.
[0009] By adopting the above technical solution, the overall sealing performance was ensured.
[0010] Furthermore, an installation opening is provided on the outer surface of one of the enamel steel plates, and a transparent acrylic base is fixedly installed inside the installation opening.
[0011] By adopting the above technical solution, it is easier to observe the internal structure.
[0012] Furthermore, a sampling port is provided on the outer surface of the transparent acrylic base, and a sampling tube is fixedly installed at the sampling port.
[0013] By adopting the above technical solution, sampling operations can be performed, which is highly functional and practical.
[0014] Furthermore, two slots are provided on the upper surface of the sampling tube, and a first gate and a second gate are installed inside the two slots. The first gate is close to the inlet port of the sampling tube, and the second gate is close to the outlet port of the sampling tube.
[0015] By adopting the above technical solution, uncontrolled sampling can be avoided.
[0016] Furthermore, a cover plate is installed on one side of the transparent acrylic base.
[0017] By adopting the above technical solution, one side of the transparent acrylic base can be shielded and protected.
[0018] In summary, the beneficial technical effects of this utility model are as follows:
[0019] 1. This utility model allows for direct assembly of enamel steel plates by simply aligning them and connecting them with bolts. Because a rectangular frame is integrally connected to the edge of the enamel steel plate, the interconnected frames effectively enhance the overall structural strength of the assembled structure, thereby improving the structural strength and connection stability of the assembled tank body. Furthermore, rubber gaskets are adhered to the outer surface of the connecting frames, located at the joint between adjacent enamel steel plates, effectively improving the sealing and waterproofing of the assembled tank body.
[0020] 2. This utility model allows for internal inspection using a transparent acrylic base when storing materials in the assembled tank body, and sampling can be performed using a sampling tube. During sampling, the first gate is first pulled upwards to a certain position, allowing the material inside the assembled tank body to fill the sampling tube. Then, the first gate is pressed down to cut off the connection between the sampling tube and the interior of the assembled tank body. Finally, the second gate is pulled upwards to allow the material inside the sampling tube to drain out. This achieves effective sampling while avoiding uncontrollable material sampling, making it highly practical. Attached Figure Description

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.
[0025] Reference Figure 1 , Figure 2 A stable, multi-layered enamel-lined assembled tank structure includes an assembled tank body 1, which is assembled from multiple enamel-lined steel plates 2. A connecting frame 3 is integrally connected to the edge of each enamel-lined steel plate 2. The connecting frame 3 is rectangular in shape, and has multiple through holes on its outer surface. Multiple connecting blocks 6 are fixedly connected to the inner walls of adjacent sides of the connecting frame 3. A threaded hole is provided in the middle of each connecting block 6, and the threaded hole corresponds to the position of the through hole. Adjacent enamel-lined steel plates 2 are fixedly connected by connecting bolts 4, which pass through the through holes and threaded holes. A rubber gasket is fitted and wrapped around the outer surface of the connecting frame 3. 7. The rubber gasket 7 and the connecting frame 3 are bonded together with glue. During the assembly, the enamel steel plates 2 can be directly aligned and then connected using the connecting bolts 4. Since the rectangular frame-shaped connecting frame 3 is integrally connected to the edge of the enamel steel plate 2, the interconnected connecting frames 3 can effectively improve the structural strength of the overall assembly structure after the assembly is completed, thereby improving the structural strength and connection stability of the assembled tank body 1. Because the rubber gasket 7 is bonded to the outer surface of the connecting frame 3, and the rubber gasket 7 is located at the connection gap between two adjacent enamel steel plates 2, it can effectively improve the sealing and waterproof performance of the assembled tank body 1.
[0026] Reference Figure 1 , Figure 2One of the enamel steel plates 2 has an installation port on its outer surface, and a transparent acrylic base 8 is fixedly installed inside the installation port. A sampling port is provided on the outer surface of the transparent acrylic base 8, and a sampling tube 9 is fixedly installed at the sampling port. Two slots are provided on the upper surface of the sampling tube 9, and a first gate 10 and a second gate 11 are inserted into the two slots. The first gate 10 is near the inlet port of the sampling tube 9, and the second gate 11 is near the outlet port of the sampling tube 9. A cover plate 5 is installed on one side of the transparent acrylic base 8, which allows for the use of... When storing materials in the main body 1, the interior can be viewed using the transparent acrylic base 8 as needed. Simultaneously, sampling can be performed using the sampling tube 9. During sampling, first pull the first gate 10 upward to a certain position so that the material inside the main body 1 can fill the inside of the sampling tube 9. Then, press down the first gate 10 to cut off the internal connection between the sampling tube 9 and the main body 1. Then, pull the second gate 11 upward to allow the material inside the sampling tube 9 to be discharged. This achieves effective sampling while avoiding uncontrollable material sampling, making it highly practical.
[0027] Working Principle: In use, multiple enamel steel plates 2 are first assembled at designated locations to form the main body 1 of the assembled tank. During assembly, the enamel steel plates 2 are aligned and then connected using connecting bolts 4. Because rectangular frame-shaped connecting frames 3 are integrally connected to the edges of the enamel steel plates 2, the interconnected connecting frames 3 effectively improve the overall structural strength of the assembled structure after assembly, thereby enhancing the structural strength and connection stability of the main body 1 of the assembled tank. Rubber gaskets 7 are adhered to the outer surface of the connecting frames 3, located at the joints between adjacent enamel steel plates 2, effectively improving the assembly... The tank body 1 is airtight and waterproof. After assembly, it can be used normally. When using the assembled tank body 1 to store materials, the internal structure can be viewed using the transparent acrylic base 8 as needed. At the same time, sampling can be performed using the sampling tube 9. When sampling, first pull the first gate 10 upward to a certain position so that the material inside the assembled tank body 1 can fill the inside of the sampling tube 9. Then, press down the first gate 10 to cut off the internal connection between the sampling tube 9 and the assembled tank body 1. Then, pull the second gate 11 upward to allow the material inside the sampling tube 9 to be discharged. This achieves effective sampling while avoiding uncontrollable material sampling.
