Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger plates, in particular to a fully welded plate heat exchanger plate structure made of duplex steel 2304. Background Art

[0002] A heat exchanger is a device used to transfer heat between fluids at different temperatures. It is widely used in many fields such as industry, civil, aerospace, etc. The performance of heat exchanger plates, as a key component of the heat exchanger, directly affects the efficiency and effect of the entire heat exchanger. With the continuous advancement of science and technology and the improvement of environmental awareness, heat exchanger plates will develop in the direction of greater efficiency, greater environmental protection, and greater intelligence.

[0003] For example, a Chinese patent (publication number: CN206601060U) discloses a plate of a plate-type heat exchanger, comprising a main body, a medium inlet, a medium outlet, a corrugated flow channel and a barrier guide structure arranged on the main body. The corrugated flow channel connects the medium inlet and the medium outlet, and the barrier guide structure divides the corrugated flow channel into several sections. The heat exchanger plate of this utility model is provided with a barrier guide structure to directionally guide the medium to flow in a "snaking" manner, thereby extending the flow stroke of the medium in the channel. This directional "snaking" flow increases the channel length on the side of the small flow medium, and the flow velocity of the small flow medium is within a reasonable range. The plate-type heat exchanger composed of the plates provided by the utility model can produce high heat transfer efficiency under conditions of a large flow ratio (greater than 3) under normal channel cross-section and single-flow structure, while ensuring convenient maintenance.

[0004] However, the strength of the plate is not high. If the plate encounters special occasions, such as occasions requiring stronger corrosion resistance and higher strength, this plate may not meet the requirements. Therefore, a fully welded plate heat exchanger plate structure made of duplex steel 2304 is proposed to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a fully welded plate heat exchanger plate structure made of duplex steel 2304, which has the advantage of high strength and solves the problem of insufficient strength in special occasions.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a fully welded plate heat exchanger plate structure made of duplex steel, comprising a plate body, a stabilizing assembly provided on the outer surface of the plate body for securing the plate body for easy transportation, a clamping assembly provided on the bottom of the stabilizing assembly for facilitating opening the stabilizing assembly, and a base fixed to the back of the stabilizing assembly;

[0016] By adopting this technical solution, the depth of the corrugated groove is set to be less than 2.6 mm, in order to avoid cracks caused by excessive extension of the material during the pressing process.

[0017] Furthermore, the stabilizing component includes a shell, two stabilizing blocks and a movable part. The shell is annular, and the outer surface of the shell is fixed to the two stabilizing blocks. The movable part is provided on the left side of the shell, and the backs of the two stabilizing blocks are fixed to the base.

[0018] By adopting this technical solution, the use of a stable component can achieve a good fixing effect on the plate body, further facilitating the loading, unloading and transportation of the heat exchanger plate structure.

[0019] Furthermore, the movable part includes a movable block and a toggle block, the movable block is movably connected to the inner cavity of the shell, the toggle block is fixed to the front of the movable block, a movable groove is opened on the front of the shell, the movable groove is connected to the inner cavity of the shell, and the movable groove is adapted to the toggle block.

[0020] By adopting this technical solution, the movable part can slide freely in the shell. When the plate body needs to be removed, it can be easily removed by sliding the movable part to the inside.

[0021] Furthermore, the clamping assembly includes a clamping block, a stabilizing plate, and a compression spring. The outer wall of the shell is provided with a clamping hole and a spring hole.

The part of the clamping block located on the inner side of the shell is adapted to the clamping groove.

[0022] By adopting this technical solution, a clamping portion is provided to fix the movable portion, thereby further improving the stability of the movable portion. When the plate body needs to be fixed, stable fixation can be ensured.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The fully welded plate heat exchanger plate structure is made of duplex steel. The plate body itself is made of stainless steel with good mechanical properties. The overall stability and sealing of the plate body are ensured by the fixation of reinforcing ribs and the fully welded structure. The plate body is fixed by the cooperation of the stabilizing components and the base, which further facilitates transportation.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 2 and Figure 6 In this embodiment, a fully welded plate heat exchanger plate structure made of duplex steel 2304 includes a plate body 1. The outer surface of the plate body 1 is provided with a stabilizing component 2 for fixing the plate body 1 for easy transportation. The bottom of the stabilizing component 2 is provided with a snap-on component 3 for facilitating the opening of the stabilizing component 2. A base 4 is fixed on the back of the stabilizing component 2.

[0034] In addition, the plate body 1 includes a base layer 101, two corrugated layers 102, two protective layers 103 and reinforcing ribs 104. The front and back sides of the base layer 101 are fixed to the two corrugated layers 102 respectively, and the opposite sides of the two corrugated layers 102 are sprayed with the two protective layers 103 respectively. The reinforcing ribs 104 are fixed to the outer surfaces of the base layer 101 and the two corrugated layers 102. The reinforcing ribs 104 can increase the sealing of the plate body 1, and the strength of the plate body 1 itself can be enhanced by cooperating with the base layer 101 and the two corrugated layers 102. The plate body 1 is provided with connecting holes on the upper and lower sides at the axis. The connecting holes are opened on the bottom surface and the processing order of punching first and then pressing is determined. The optimization of this step significantly reduces the pressing defects, especially the generation of cracks, thereby ensuring the quality and performance of the plate. The plate body 1 is circular as a whole. The circular design can balance the stress distribution during the pressing process, thereby effectively reducing the pressing deformation.

[0035] It should be further explained that the base layer 101 and the two corrugated layers 102 are both made of 2304 bidirectional stainless steel. 2304 bidirectional stainless steel has good mechanical properties and high strength. The two corrugated layers 102 are provided with multiple corrugated grooves on the opposite sides. The corrugated grooves can increase the heat exchange area and further improve the heat exchange efficiency. The depth of the multiple corrugated grooves is less than 2.6 mm. The depth of less than 2.6 mm can effectively avoid cracks caused by excessive elongation of the material during the pressing process. The multiple corrugated grooves are all elliptical, and the corrugated grooves can also be set to chocolate-like. This shape can also effectively increase the heat exchange area.

[0036] It can be known that the two protective layers 103 are both made of polytetrafluoroethylene, the reinforcing ribs 104 are fixed to the base layer 101 and the two corrugated layers 102 by welding, and the base layer 101 and the two corrugated layers 102 are fixed by welding. Polytetrafluoroethylene has excellent heat resistance, cold resistance, corrosion resistance, aging resistance, non-stickiness and low friction coefficient. It can protect the plate body 1 and ensure that the plate body 1 can work under certain corrosive conditions.

[0037] It should be noted that the cooperation between the base layer 101 and the corrugated layer 102 can effectively improve the overall strength and improve the heat transfer efficiency. The cooperation between the protective layer 103 and the reinforcing ribs 104 can greatly enhance the corrosion resistance and sealing of the plate body 1, thereby greatly improving the service life of the plate body 1.

[0038] Please refer again Figure 1 and Figures 3 to 5 In order to facilitate transportation, the stabilizing component 2 in this embodiment includes a shell 201, two stabilizing blocks 202 and a movable part 203. The shell 201 is annular, and the outer surface of the shell 201 is fixed to the two stabilizing blocks 202. The movable part 203 is provided on the left side of the shell 201, and the backs of the two stabilizing blocks 202 are fixed to the base 4.

[0039] In addition, the movable part 203 includes a movable block 2031 and a toggle block 2032. The movable block 2031 is movably connected to the inner cavity of the outer shell 201, and the toggle block 2032 is fixed to the front of the movable block 2031. A movable groove is provided on the front of the outer shell 201. The provision of the movable groove can facilitate the movement of the toggle block 2032 and further facilitate the adjustment of the specific position of the movable block 2031. The movable groove is communicated with the inner cavity of the outer shell 201, and the movable groove is adapted to the toggle block 2032.

[0040] It can be seen that the clamping assembly 3 includes a clamping block 301, a stabilizing plate 302, and a compression spring 303. The outer wall of the housing 201 is provided with a clamping hole and a spring hole. The outer side of the clamping hole is connected to the spring hole. The connection between the clamping hole and the spring hole can ensure that the force of the compression spring 303 is smoothly transmitted to the clamping block 301, further promoting the clamping block 301 to complete the clamping and realize the fixation of the movable block 2031. The clamping block 301 passes through the housing 201 through the clamping hole. Inside, the bottom of the stabilizing plate 302 and the outer surface of the clamping block 301 are fixed with the compression spring 303, and the end of the compression spring 303 away from the stabilizing plate 302 is fixed to the shell 201. The outer surface of the movable block 2031 is provided with a clamping groove, and the clamping block 301 and the part located on the inner side of the shell 201 are adapted to the clamping groove. The clamping block 301 is adapted to the clamping groove, which can ensure that the clamping block 301 can smoothly enter the clamping groove, thereby further realizing the fixation of the movable block 2031.

[0041] In this embodiment, by cooperating with the clamping block 301 and the movable block 2031, the plate body 1 can be removed at any time. It is only necessary to pull the clamping block 301 outward to separate the clamping block 301 from the clamping slot, and then move the toggle block 2032. This method can easily install and fix the plate body 1, and further facilitate the transportation of the plate body 1.

[0042] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The power supply provided by the battery is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0043] The working principle of the above embodiment is:

[0044] The cooperation between the base layer 101, the corrugated layer 102 and the reinforcing ribs 104 can enhance the stability and sealing of the plate body 1, further enhance its own strength, and increase the corrosion resistance by spraying the protective layer 103, greatly improving the service life of the plate body 1, and making the plate body 1 suitable for long-term operation or working in a highly corrosive environment. When the plate body 1 needs to be fixed, it is only necessary to align the outer surface of the plate body 1 with the inner side of the shell 201, and hold the toggle block 2032 to make the movable block 2031 and the shell 2032 move. 01 together to wrap the outer surface of the plate body 1, pull out the clamping block 301 at the same time, and move the movable block 2031 to align the clamping block 301 with the clamping groove, and then release the clamping block 301. Under the action of the compression spring 303, the clamping block 301 is prompted to enter the clamping groove to achieve the clamping of the movable block 2031. The plate has good mechanical properties, high strength and corrosion resistance, and is easy to carry and transport. The plate reduces pressing deformation, avoids the generation of pressing cracks, and further improves the overall performance of the plate.
