Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and more specifically, to a heat exchange plate structure. Background Technique

[0002] A plate heat exchanger is composed of concave and convex stainless steel plates formed by stamping. The concave and convex patterns between two adjacent plates are combined relatively at 180 degrees. Therefore, the concave and convex ridge lines between the two plates of the plate heat exchanger form staggered contact points. After the contact points are combined by vacuum welding, a high-pressure resistant staggered flow structure of the plate heat exchanger is formed. These staggered flow structures cause strong turbulence of the cold and hot fluids in the plate heat exchanger to achieve a high heat exchange effect. A plate heat exchanger is composed of a group of corrugated metal plates. There are four corner holes on the plates for two liquids for heat transfer to pass through. The metal plates are installed in a frame with a fixed plate and a movable pressing plate on one side and are clamped by clamping bolts. Sealing gaskets are installed on the plates to seal the fluid channels and guide the fluids to flow into their respective flow channels alternately to form heat exchange. The flow rate, physical properties, pressure drop and temperature difference of the fluids determine the number and size of the plates. The corrugated plates not only increase the degree of turbulence but also form many support points sufficient to withstand the pressure difference between the media.

[0003] Since when the existing adjustable heat exchange plates are adjusted, the pressure is too high, which easily causes the ends of the intermediate support plates to bend under the action of the pressure and cause leakage. The on-site steam supply pipeline has a temperature of 180 °C to meet the demand of the subsequent label sleeving. The EPDM material can withstand a temperature of about 140 °C. Although the steam at the sterile water inlet has decreased, it still exceeds the temperature tolerance range of the EPDM material, resulting in the deformation of the sealing ring baffle and the inability to be completely sealed, causing the sealing ring to run out. Therefore, we propose a heat exchange plate structure to solve the above existing problems. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment:

[0029] Please refer to Figures 1-4 , a heat exchange plate structure, including a splint 1, a plate 2 installed between the splints 1 and bolts 3, nuts 4 screwed at both ends of the bolts 3, a pipe 5 passing through the plate 2, and a steam supply pipeline 10 in conduction connection with the pipe 5. Symmetrically fixed to the part of the pipe 5 corresponding to the steam supply pipeline 10 are support plates 6 arranged in a circular structure;

[0030] A sealing ring 7 is closely attached between the support plate 6 and the plate 2;

[0031] A reinforcing rod 8 arranged in a columnar structure is welded between the support plates 6, and a plurality of reinforcing rods 8 are arranged in the radial position of the support plates 6;

[0032] It should be noted that in the existing plate heat exchanger, when the adjustable plate 2 for heat exchange is adjusted, due to excessive pressure, the end of the intermediate support plate 6 is likely to be bent under the pressure, resulting in the displacement of the sealing ring 7 and leakage. Therefore, a reinforcing rod 8 is welded between the two support plates 6 to enhance the structural strength and reduce the leakage situation.

[0033] As Figure 2 shown, at the combined part of the end of the reinforcing rod 8 and the support plate 6, a reinforcing rib 9 arranged in a right triangle structure is welded, and a plurality of reinforcing ribs 9 are arranged in the radial position of the reinforcing rod 8;

[0034] It should be noted that by setting the reinforcing rib 9, the strength, rigidity and torsional resistance of the reinforcing rod 8 are enhanced, and the warping and deformation of the product caused by uneven stress due to the diameter difference of the reinforcing rod 8 can be overcome, so as to increase the strength of the joint surface.

[0035] As Figure 4 shown, there are specifically three reinforcing rods 8, and the included angle between two adjacent reinforcing rods 8 corresponding to the axis line of the pipeline 5 is 120°;

[0036] It should be noted that the force on the connecting part of the reinforcing rod 8 and the support plate 6 is made uniform, thus ensuring the positioning effect on the support plate 6.

[0037] As Figure 2 shown, the weld seam between the reinforcing rod 8 and the support plate 6 is arranged around the end part of the reinforcing rod 8;

[0038] It should be noted that by increasing the length of the weld seam between the reinforcing rod 8 and the support plate 6, the welding stability between the support plate 6 and the reinforcing rod 8 can be effectively improved.

[0039] As Figure 2 shown, an opening is provided at the butt joint of the plate 2 and the pipeline 5, and the opening is conductively connected to the pipeline 5. The sealing ring 7 is made of ethylene propylene diene monomer rubber;

[0040] It should be noted that by providing the sealing ring 7 at the opening, the leakage at the connecting part of the opening and the pipeline 5 can be effectively prevented, and the sealing ring 7 is made of EPDM material and can withstand a high temperature of about 140°C.

[0041] As Figure 4 shown, the included angle between the two connection parts of the steam supply pipeline 10 and the pipeline 5 at both ends is 90°, and there is a gap between the two ends of the steam supply pipeline 10;

[0042] It should be noted that interference with the connection part between the steam supply pipeline 10 and the pipeline 5 is avoided during the process of welding multiple reinforcing rods 8 between the support plates 6.

[0043] During use: Since the adjustable plate 2 for heat exchange in the existing plate heat exchanger is prone to bending of the end part of the intermediate support plate 6 under pressure during adjustment, resulting in displacement of the sealing ring 7 and leakage. Therefore, a reinforcing rod 8 is welded between the two support plates 6 to prevent the support plate 6 from deforming, and thus ensure that the sealing ring 7 is not displaced, so as to enhance the structural strength and reduce the leakage situation.

[0044] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
