Description

Technical Field

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

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

[0003] First, traditional water plants generally use concrete structures, which rely on formwork support and grouting, and are assembled using a skid-mounted method, resulting in long construction cycles and poor sealing performance.

[0004] Secondly, although the improved technology introduces a welded structure (by overlapping the front and back and then welding the top and bottom sections), which enhances sealing, it still faces serious problems: the label plates are not standardized in size, and the existing production capacity cannot meet the water plant's demand for hundreds or thousands of labels. Specifically, label plate production relies on manual loading and unloading, resulting in extremely low installation efficiency, especially when the label plates vary in size (some are long and some are short), making automated production difficult.

[0005] In addition, the thick corrugated board forming technology is not mature - the current method of producing corrugated boards using bending machines is only suitable for manufacturing thin boards (such as 1-2mm thick container boards), and this method cannot be applied to pressing the deep corrugated boards (5-6mm thick corrugated boards) required for water plants.

[0006] During the process of preparing thick corrugated plates by pressing: the plate material will rebound and deform, and the size is difficult to control; if asymmetrical steel is used for welding (such as the welding of a combination of upper channel steel and lower pipe), asymmetrical stress will be triggered, causing the product to deform and form an arched structure similar to an arch bridge. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a prefabricated standard plate for water tanks that is conducive to automated production in factories.

[0008] This type of prefabricated standard plate for water tanks, which is conducive to automated production in factories, includes: side beams and corrugated plates formed by mold pressing (molds worth millions of yuan have been designed and production lines worth tens of millions of yuan have been built). Side beams are welded to both sides of the corrugated plates; the corrugation direction of the corrugated plates is parallel to the length direction of the side beams, or the corrugation direction of the corrugated plates is perpendicular to the length direction of the side beams.

[0009] 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 (full water height, working medium, operating conditions and service life)), and the thickness of the corrugated plate is 0.1 cm to 0.8 cm.

[0010] Prefabricated standard panels are divided into three types: Type 1, Type 2, and Type 3.

[0011] In the first type of prefabricated standard plate, end beams are welded to both ends of the side beams;

[0012] In the second type of prefabricated standard plate, 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 part of the corrugated plate is not welded to the side beam, forming an unwelded section.

[0013] In the third type of prefabricated standard plate, no end beams are set at both ends of the side beam. At both ends of the side beam, the two ends of the corrugated plate extend beyond the side beam by a certain length. The two extended parts of the corrugated plate are not welded to the side beam, forming unwelded sections at both ends of the corrugated plate.

[0014] 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.

[0015] Preferably, the wavelength of the sine wave is 0.15 m to 0.30 m.

[0016] As a preferred option, the width of the prefabricated standard plate is 1 m to 2 m, and the length of the prefabricated standard plate is 1 m to 12 m, which enables mass production and greatly improves efficiency.

[0017] Preferably, the mold is provided with positioning roller grooves, pressing roller grooves, and take-up roller grooves; an 800-ton press equipped with positioning rollers, pressing rollers, and take-up rollers is respectively installed above the positioning roller grooves, pressing roller grooves, and take-up roller grooves; a heating layer is provided on the outer surface of the pressing roller, which can reduce internal stress and rebound deformation during the cold forming process, thereby stabilizing the dimensional accuracy of the corrugated plate and solving the problem of dimensional loss of control caused by rebound when pressing thick plates; the positioning roller is used to guide the feeding of the corrugated plate roll, the take-up roller is used to adjust the tension of the roll, and the pressing roller is used to work with the positioning roller and take-up roller to press the roll.

[0018] Preferably, the temperature of the heating layer is 40℃~60℃.

[0019] Preferably, a stretching device is also provided for pre-stretching the corrugated plate before welding it to the side beam and / or end beam. The stretching device stretches the corrugated plate by 2 to 3 cm in advance to counteract the shrinkage of the corrugated plate that occurs during welding.

[0020] As a preferred option, the side beams welded on both sides of the corrugated plate adopt a symmetrical structure, such as angle steel, channel steel or square tube, to further eliminate the risk of deformation during welding.

[0021] Preferably, a robot is also provided for synchronous welding of corrugated plates on both sides of the side beam and both sides of the end beam.

[0022] Preferably, the corrugated plate is made of titanium steel or stainless steel with a thickness of 0.5 cm to 0.6 cm. The surface of the corrugated plate is also coated with a paint coating, which includes an 80 to 120 μm thick epoxy zinc-rich primer layer and a 60 to 100 μm thick polyurethane topcoat layer. This coating 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 can form 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.

[0023] The beneficial effects of this utility model are:

[0024] This invention designs a standardized standard plate that can be produced on million-dollar molds and tens-of-millions-dollar automated production lines. This corrugated plate can be mass-produced, solving the problem of low efficiency in the production of traditional non-standard corrugated plates. The corrugated plate has a waveform depth of 5 cm to 15 cm, which can disperse water pressure stress. It also includes a tensioning device for pre-stretching the corrugated plate before welding it to the side beams and / or end beams, which can counteract the shrinkage deformation of the corrugated plate during welding. The use of symmetrical side beams (angle steel / channel steel) and synchronous robotic welding can improve bending strength and eliminate the risk of arching distortion. Three types of standard plates can adapt to diverse scenarios. The composite coating on the surface of the corrugated plate can form a chemical bond-physical interlocking double protective layer, providing corrosion resistance and a long service life. It has certain functional expandability, allowing selection of sinusoidal / arc / trapezoidal corrugated plates according to actual application scenarios to optimize fluid resistance and improve anti-sludge accumulation efficiency. The unwelded section is used for fine-tuning the dimensions during welding, and with the socket interface (positioning pin + spring lock), it can be quickly spliced ​​and welded into assembled standard plates.
