Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment devices, and in particular relates to a water tank that is conducive to automated assembly and production in factories. Background Technology

[0002] The following technological bottlenecks exist in the current water treatment equipment manufacturing field:

[0003] Traditional water treatment plants (such as sedimentation tanks and biological treatment tanks) generally use concrete casting structures, relying on on-site formwork support for grouting construction. The construction cycle for a single tank is long, and the leakage rate at the joints is high (skid-mounted assembly makes it difficult to guarantee sealing). Although steel plate welding structures have been introduced, the lack of standardization of standard plate dimensions makes mass production impossible. As a result, when expanding a water treatment plant, thousands of irregularly shaped standard plates need to be customized, and manual assembly is inefficient.

[0004] Existing bending machine processes are only suitable for bending thin plates (such as 1-2mm container plates). When bending corrugated plates (5-6mm thick) required for water treatment, the material rebounds and deforms, resulting in errors and irregularities in the waveform. More seriously, the use of asymmetrical steel sections for welding easily induces asymmetrical stress, leading to overall arching deformation of the corrugated plate.

[0005] During on-site assembly, dimensional errors in the standard plates (gap between adjacent plates exceeding 3mm) can lead to loosening and leakage after prolonged use due to insufficient welding strength. Additionally, the poor adhesion of ordinary coatings causes them to peel off quickly under corrosive wastewater conditions. These issues pose risks of welding deformation and corrosion. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a water tank that is conducive to automated assembly production in factories.

[0007] This type of water tank, which is conducive to automated assembly and production in factories, includes a bottom plate, a cover plate, and multiple assembled standard plates that are spliced ​​and welded together between the bottom plate and the cover plate; the bottom plate and the cover plate are also multiple assembled standard plates that are spliced ​​and welded together.

[0008] The prefabricated standard plate includes side beams and corrugated plates formed by mold pressing. Side beams are welded to both sides of the corrugated plate, and the surface of the corrugated plate is also coated with paint. The corrugated plate has a corrugated direction that is parallel to the length direction of the side beams, or the corrugated plate has a corrugated direction that is perpendicular to the length direction of the side beams.

[0009] Prefabricated standard panels are divided into three types: Type 1, Type 2, and Type 3. The water tank is assembled and welded from Type 1, Type 2, and Type 3 prefabricated standard panels. In Type 1 prefabricated standard panels, end beams are welded to both ends of the side beams. In Type 2 prefabricated standard panels, an end beam is welded to one end of the side beam. At the other end of the side beam, the end of the corrugated plate extends beyond the side beam by a certain length, and the extended portion of the corrugated plate is not welded to the side beam, forming an unwelded section. In Type 3 prefabricated standard panels, no end beams are provided at either end of the side beam. At both ends of the side beam, the ends of the corrugated plate extend beyond the side beam by a certain length, and neither of the extended portions of the corrugated plate is welded to the side beam, forming unwelded sections at each end of the corrugated plate.

[0010] The waveform depth of the corrugated plate is 5 cm to 15 cm (the waveform depth can be adjusted according to the water pressure conditions), and the thickness of the corrugated plate is 0.1 cm to 0.8 cm; the width of the assembled standard plate is 1 m to 2 m, and the length of the assembled standard plate is 1 m to 12 m, realizing mass production and greatly improving efficiency.

[0011] As a preferred option, the corrugated plate is a continuously formed sine wave, arc, trapezoid, or rectangle. The waveform conforms to fluid mechanics. Compared with the rectangular wave produced by existing bending machines, the arc wave has significant advantages—it can reduce water flow resistance and effectively prevent mud accumulation.

[0012] Preferably, the wavelength of the sine wave is 0.15 m to 0.30 m.

[0013] As a preferred option: each water tank can be used independently for water treatment processes (such as A). 2 In processes such as O2, MBR, and CASS, multiple water tanks can be combined, spliced, and welded to meet the requirements of large, medium, and small water volume treatment processes, forming a small modular sewage treatment system. The small modular sewage treatment system includes a pretreatment tank, sedimentation tank, biological treatment tank, membrane tank, and disinfection effluent tank.

[0014] Preferably, the water tank has a length of 3 m to 12 m, a width of 1 m to 3 m, and a height of 1.5 m to 3 m.

[0015] Preferably, the corrugated plate is made of titanium steel or stainless steel plate with a thickness of 0.5 cm to 0.6 cm. The paint coating includes an 80 to 120 μm thick epoxy zinc-rich primer layer and a 60 to 100 μm thick polyurethane topcoat layer. This can prevent the corrugated plate from being electrochemically corroded and extend its service life. The epoxy zinc-rich primer layer provides a good adhesion base for the polyurethane topcoat layer (the surface energy of the epoxy zinc-rich primer forms a dual combination of chemical bonds and physical interlocking with the subsequent polyurethane topcoat, preventing the topcoat from falling off due to insufficient adhesion). The polyurethane topcoat layer has wear resistance and corrosion resistance.

[0016] The beneficial effects of this utility model are:

[0017] This utility model improves manufacturing and installation efficiency and accuracy by designing standardized standard panels and using three types of prefabricated standard panels. During on-site installation, the dimensions can be finely adjusted through unwelded sections. The corrugated panels have a certain corrugation depth, which can disperse water pressure stress and has high bending strength, thus avoiding arch deformation. The corrugated panels are fully welded to the side beams, and unwelded sections can be repaired on-site, eliminating the risk of leakage in the concrete structure and providing high welding strength. The surface of the corrugated panels has a composite layer of epoxy zinc-rich primer and polyurethane topcoat, which is corrosion-resistant and has a long service life. Different materials can be selected for the corrugated panels according to the working conditions, which can reduce maintenance costs. Multiple water tanks can be combined to form pretreatment tanks, sedimentation tanks, and other modules, enabling rapid construction of template tanks, saving time and increasing efficiency.

[0018] The water tank designed in this utility model is conducive to automated assembly and production in factories. It facilitates automated batch welding and assembly, improves product quality and automated production efficiency, reduces the production cost of non-standard parts, and also facilitates batch transportation of standard box process packages and overall on-site assembly.

The surface of the corrugated plate 1 is also coated with paint. The corrugated plate 1 is a continuously formed sinusoidal waveform, conforming to fluid mechanics.

The polyurethane topcoat layer has wear resistance and corrosion resistance.

[0036] The prefabricated standard plate 100 is divided into three types: Type 1, Type 2, and Type 3.
