Description

Technical Field

[0001] The utility model relates to the field of heat exchangers, in particular to a sealing box for a heat exchanger. Background Art

[0002] The plate-and-frame fully welded heat exchanger combines the advantages of plate heat exchangers and shell-and-tube heat exchangers. It not only maintains the advantages of traditional plate heat exchangers, such as high heat transfer efficiency, compact structure, high temperature resistance, good sealing performance, stability and reliability, but can also be used under higher pressure and temperature conditions. It is suitable for steam condensation and liquid-liquid heat exchange, and is particularly suitable for heat exchange requirements of special media in industries such as power, petrochemical, coking, pharmaceutical, metallurgy, refrigeration, and pulp and paper industry.

[0003] However, the pressure bearing capacity of the plate-frame fully welded heat exchanger mainly depends on the sealing structure of the column and the box plate. Once the sealing structure has problems, the pressure bearing capacity of the entire equipment is almost zero. That is, compared with the traditional detachable heat exchanger, the advantages of high heat exchange efficiency, high pressure bearing capacity, and high temperature resistance are all gone. The existing plate-frame fully welded heat exchanger has low installation efficiency and insufficient sealing. Utility Model Content

[0004] In order to overcome the disadvantage of poor sealing of the existing plate-frame heat exchanger, the utility model provides a heat exchanger sealing box.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a heat exchanger sealing box, including side box plates, a top plate, a sealing plate, columns, protrusions, circular holes, and sealing members, wherein four side box plates fixedly connected together form an outer frame, the openings at both ends of the frame are respectively fixedly connected with the top plates, the outer frame is fixedly connected with an inner frame, the inner frame is composed of four sealing plates fixedly connected together, a sealing member is arranged between the columns and the sealing plates, a plurality of protrusions are arranged in sequence on the outer walls of the columns, and a plurality of circular holes for matching the protrusions are arranged in sequence on the side box plates.

[0006] According to another embodiment of the utility model, the sealing component further includes a gasket and a supporting spring washer.

[0007] According to another embodiment of the utility model, a groove for matching a sealing member is further provided between the column and the sealing plate.

[0008] According to another embodiment of the present invention, the gasket is further comprised of a curved sheet.

[0009] According to another embodiment of the utility model, four side box panels are further welded and fixed together.

[0010] According to another embodiment of the present invention, four sealing members are further welded and fixed together.

[0011] According to another embodiment of the utility model, a flange is further provided on the side box plate.

[0012] According to another embodiment of the utility model, a hanging ring is further provided on the top plate of the sealing box.

[0013] According to another embodiment of the utility model, the top plate at the bottom of the sealing box is further provided with supporting feet.

[0014] The beneficial effect of the utility model is that the utility model can quickly locate the positions of the column and the side box plate through the convex points on the column and the round holes on the side box plate, and can prevent the side box plate from moving radially. The sealing performance of the sealing is improved through the sealing element. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a structural schematic diagram of the utility model; Figure 2 It is a structural schematic diagram of the sealing element of the utility model.

[0020] A sealed box for a heat exchanger comprises a side box plate 1, a top plate 2, a sealing plate 3, a column 4, a convex point 5, a circular hole 6 and a sealing member 7. Four side box plates 1 are fixedly connected together to form an outer frame. The top plates 2 are fixedly connected to the openings at both ends of the frame respectively. An inner frame is fixedly connected inside the outer frame. The inner frame is composed of four sealing plates 3 fixedly connected together. A sealing member 7 is arranged between the column 4 and the sealing plate 3. Several convex points 5 are arranged in sequence on the outer wall of the column 4. Several circular holes 6 for matching the convex points 5 are arranged in sequence on the side box plates 1.

[0021] The sealing member 7 includes a gasket 71 and a supporting spring washer 72 .

[0022] A groove for fitting the sealing member 7 is provided between the column 4 and the sealing plate 3 .

[0023] The gasket 71 is a curved sheet.

[0024] The four side box panels 1 are welded and fixed together.

[0025] The four sealing members 7 are fixed together by welding.

[0026] A flange 8 is provided on the side box plate 1.

[0027] A hanging ring 9 is provided on the top plate 2 at the top of the sealing box.

[0028] The top plate 2 at the bottom of the sealed box is provided with a support leg 10

[0029] The circular hole 6 on the side box plate 1 is aligned with the convex point 5 on the column 4, so that the quick side box plate 1 can be quickly positioned. This can also prevent the side box plate 1 from moving radially, thereby improving the structural strength of the sealed box. When the side box plate 1 presses the column 4, the sealing member 7 is directly pressed against the sealing member 7 and fits tightly together, thereby greatly improving the sealing performance of the sealed box.
