Description

Technical Field

[0001] The embodiments of the present application relate to the field of fixing, and in particular to a connection and fixing device for a plate heat exchanger. Background Art

[0002] A heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Stainless steel heat exchangers are currently widely used in many fields. Made of food-grade stainless steel, this heat exchanger has outstanding rust and scale resistance.

[0003] In the prior art, when stainless steel plate heat exchangers are used, there is a need for multiple heat exchangers to work simultaneously. However, direct stacking or placement will cause the heat exchangers to shift or even tilt or fall during operation, resulting in reduced working efficiency of the heat exchangers. Summary of the Invention

[0004] An embodiment of the present application discloses a fixing device for a plate heat exchanger, which is used to alleviate the reduction in the working efficiency of the heat exchanger caused by displacement, even tilting or tipping of the heat exchanger, and improve the working efficiency of the heat exchanger.

[0005] The present application provides a fixing device for a plate heat exchanger, comprising:

[0006] U-shaped grooves, connecting gussets and bolts;

[0007] A bolt hole is provided at the upper end of the U-shaped groove;

[0008] The bolts connect the U-shaped groove and the connecting gusset plate;

[0009] The bolt head is sunken to form a receiving groove, and the receiving groove matches the bolt tail.

[0010] Optionally, the fixing device further includes:

[0011] Wings are provided on both sides of the connecting gusset plate;

[0012] Both sides of the tail portion of the wing portion extend backward to form a tail wing.

[0013] Optionally, the tail wing is provided with a through hole matching the bolt hole.

[0014] Optionally, the bolt connection between the U-shaped groove and the connecting gusset plate includes:

[0015] The bolt passes through the through hole and the bolt hole to connect the U-shaped groove and the connecting buckle plate.

[0016] Optionally, a notch matching the heat exchanger fin is provided on the outside of the U-shaped groove.

[0017] Optionally, a pipe opening is provided on the outer side of the U-shaped groove.

[0018] Optionally, the connecting buckle plate is provided with an exhaust port.

[0019] Optionally, a limiting protrusion is provided on one side of the lower end of the U-shaped groove, and a limiting hole matching the limiting protrusion is provided at a relative position on the other side.

[0020] Optionally, the surface of the fixing device is coated with an anti-corrosion coating.

[0021] Optionally, the U-shaped groove and the connecting buckle plate are connected in a detachable manner.

[0022] It can be seen from the above technical solution that the head of the bolt connecting the U-shaped groove and the connecting buckle plate is provided with a recess matching the tail, which limits the position of the fixing device when it is stacked as a whole. The heat exchangers are stacked in an orderly manner through the fixing device, which reduces the working efficiency of the heat exchanger caused by displacement or even tilting or tipping of the heat exchanger, thereby improving the working efficiency of the heat exchanger.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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] The embodiment of the present application provides a connecting and fixing device for a plate heat exchanger, which is used to alleviate the situation where the working efficiency of the heat exchanger is reduced due to displacement, tilting or tipping of the heat exchanger, thereby improving the working efficiency of the heat exchanger. The positional relationship of each component described in the following embodiment is based on Figure 1 As the basis.

[0034] See Figures 1 to 5 The embodiment of the present application discloses a fixing device for a plate heat exchanger, which is used to alleviate the reduction in the working efficiency of the heat exchanger caused by displacement or even tilting or tipping of the heat exchanger, thereby improving the working efficiency of the heat exchanger.

[0035] The present application provides a fixing device for a plate heat exchanger, comprising:

[0036] U-shaped groove 1, connecting plate 2 and bolt 3;

[0037] The upper end of the U-shaped groove 1 is provided with a bolt hole 4;

[0038] The bolt 3 connects the U-shaped groove 1 and the connecting gusset plate 2;

[0039] The head of the bolt 3 is sunken to form a receiving groove 5 , and the receiving groove 5 matches the tail 14 of the bolt 3 .

[0040] Among them, the bolt holes 4 of the U-shaped groove 1 are located on both side wings of the upper end of the U-shaped groove 1. On the outside of the middle part of the U-shaped groove 1, notches 9 for accommodating the heat sink are evenly distributed according to the size of the heat sink of the plate heat exchanger. The notches 9 are mainly used to fix the position of the heat exchanger fins, and secondly, they have the function of accelerating air circulation to cool the plate heat exchanger and accelerating the circulation of vaporized liquid.

[0041] The exhaust port 11 in the connecting buckle plate 2 is mainly used to accelerate air circulation to cool the plate heat exchanger and accelerate the discharge of vaporized liquid and support the plate heat exchanger. The plate radiator is provided with a pipe for collecting and discharging liquefied gas, which extends out of the fixing device through the pipe port 10.

[0042] In order to prevent the overflowed vaporized liquid from corroding the fixture, a layer of anti-corrosion coating is sprayed on the surface of the fixture. The coating is used to isolate the fixture body from contact with the air and slow down the oxidation rate of the fixture.

[0043] The U-shaped groove 1 and the connecting buckle plate 2 are connected by bolts 3. The upper end of the U-shaped groove 1 and the tail of the tail wing 7 of the connecting buckle plate 2 are provided with bolt holes 4 and through holes 8 through which the bolts 3 can pass. The bolts 3 pass through the bolt holes 4 and through holes 8. The tail kit is installed at the tail 14 of the bolt 3, and the bolt 3 is fixed with the head of the bolt 3 to connect the U-shaped groove 1 and the connecting buckle plate 2.

[0044] In actual use, please refer to Figure 5 , two fixing devices of the same model form a rectangular frame that matches the size of the plate heat exchanger, and multiple rectangular frames are stacked in order through limiting components. The bottom end of the U-shaped groove 1 is provided with a limiting protrusion 12 and a limiting hole 13. When stacking and connecting, the limiting protrusion 12 is inserted into the limiting hole 13 to clamp and close the connecting buckle plate 2. Secondly, the head of the bolt 3 is recessed to form a receiving groove that matches the kit of the tail 14. When stacking the fixing devices, the limiting protrusion 12 and the limiting hole 13 can assist in limiting multiple fixing devices and plate heat exchangers to achieve the effect of forming a rectangular frame to support and fix the plate heat exchanger.

[0045] It can be seen from the above technical solution that the head of the bolt 3 connecting the U-shaped groove 1 and the connecting buckle plate 2 is provided with a depression matching the tail 14, which cooperates with the limiting protrusion 12 and the limiting hole 13 at the lower end of the U-shaped groove to limit the position of the fixing device as a whole when stacking. The heat exchanger is stacked in an orderly manner through the fixing device, which reduces the reduction in the working efficiency of the heat exchanger due to displacement or even tilting or tipping of the heat exchanger, thereby improving the working efficiency of the heat exchanger.

[0046] It should be noted that the above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
