Description

Technical Field

[0001] This utility model relates to the field of shell-and-tube condenser technology, and in particular to a shell-and-tube condenser that is easy to clean and assemble. Background Technology

[0002] Shell-and-tube condensers are key heat exchange equipment in refrigeration, chemical, and other fields. Their core structure includes a shell and tubes, end caps, and internal heat exchange tubes. They achieve condensation through heat exchange between the tube-side and shell-side media. During long-term use, scale and impurities can easily accumulate inside the condenser, requiring regular disassembly and cleaning to ensure heat exchange efficiency.

[0003] In existing shell-and-tube condensers, the shell and end caps are mostly connected by flanges, secured by bolts evenly distributed along the flange circumference. However, the large number of bolts required necessitates individual disassembly or tightening of multiple bolts, making the operation cumbersome and time-consuming, and increasing the labor costs for cleaning and maintenance.

[0004] Therefore, we propose a shell-and-tube condenser that is easy to clean and assemble. Utility Model Content

[0005] In view of this, the present invention provides a shell-and-tube condenser that is easy to clean and assemble, in order to solve the problem of low disassembly and assembly efficiency between the shell and end cap of the existing shell-and-tube condenser.

[0006] A shell-and-tube condenser that is easy to clean and assemble includes a tube shell, end caps, and clamps. The end of the tube shell is provided with an integral flange, the flange has a pin hole, and a pin is fixedly connected to the rounded end face of the end cover, the pin can be aligned and inserted into the pin hole. An arc-shaped clamping block is fixedly connected to the inner wall of the clamp. A V-shaped groove is provided on the surface of the clamping block that clamps inward. When the flange and the round edge of the end cover are in contact, the V-shaped groove can simultaneously lock onto the flange and the circumference of the round edge.

[0007] Preferably, the length of the aforementioned pin is less than the depth of the pin hole.

[0008] Preferably, a sealing gasket is also installed between the flange and the end cover, and the sealing gasket has a round hole, through which the pin can be aligned and passed.

[0009] Preferably, the aforementioned clamping block is made of high-strength, wear-resistant stainless steel, and multiple clamping blocks are evenly arranged on the inner sidewall of the clamping hoop.

[0010] Preferably, the clamp is made of carbon steel and includes an upper half-ring and a lower half-ring, the ends of which are fixedly connected by bolts.

[0011] Preferably, the lower half of the ring hoop has thickened portions at both ends, with threaded holes on the thickened portions, and a through hole at the end of the upper half of the ring hoop, with one end of the bolt passing through the through hole and threadedly connected to the threaded hole.

[0012] Implementing the embodiments of this utility model will have the following beneficial effects: The aforementioned shell-and-tube condenser, which is easy to clean and assemble, was adopted. The clamps, clamps, and V-grooves are used to press and fix the pipe shell from the circumference of the flange and end cap without affecting the sealing effect. This achieves boltless installation, enables quick disassembly and assembly, and improves the disassembly and assembly efficiency before and after cleaning. The pre-positioning structure of "pin-hole" allows for quick alignment of the flange and end cap of the pipe shell, eliminating the alignment process of traditional bolted connections. This design is simple, highly adaptable, and requires no complex auxiliary components, making it easy to mass-produce and replace, and applicable to a wide range of situations.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0019] Please see Figure 1-5 A shell-and-tube condenser that is easy to clean and assemble includes a shell 100, an end cap 200, and a clamp 300; wherein, the end of the shell 100 is provided with an integral flange 101, the flange 101 is provided with a pin hole 102, and a pin 202 is fixedly connected to the round edge 201 end face of the end cap 200, the pin 202 can be aligned and inserted into the pin hole 102. In implementation, such as Figure 5 As shown, an arc-shaped clamping block 500 is fixedly connected to the inner wall of the clamp 300. A V-shaped groove 501 is provided on the surface of the clamping block 500 that clamps inward. When the flange 101 is in contact with the round edge 201 of the end cover 200, the V-shaped groove 501 can be simultaneously locked on the flange 101 and the circumference of the round edge 201.

[0020] Note: The opening angle of the V-groove 501 is 30°-60°, the inner wall of the V-groove 501 is smooth, and the maximum opening width of the V-groove 501 is greater than the sum of the thicknesses of the flange 101, the round edge 201, and the sealing gasket 400.

[0021] Specifically, the length of the pin 202 is less than the depth of the pin hole 102. The main purpose of this design is to prevent the pin 202 from protruding from the other end of the pin hole 102, thereby affecting the position of the clamping block 500. In implementation, if the sealing gasket 400 is thick, the length of the pin 202 can be appropriately increased, as long as one end of the pin 202 does not protrude from one end of the pin hole 102 after the clamping clamp 300 is tightened.

[0022] like Figure 4 In the middle, a sealing gasket 400 is also installed between the flange 101 and the end cover 200. The sealing gasket 400 has a round hole 401, and the pin 202 can be aligned and pass through the round hole 401. The sealing gasket 400 is a rubber sealing gasket.

[0023] In implementation, such as Figure 5 As shown, the clamping block 500 is made of high-strength wear-resistant stainless steel, and multiple clamping blocks 500 are evenly arranged on the inner side wall of the clamping hoop 300. In implementation, 4, 6, 8, 10 or 12 can be set, and the appropriate size can be selected according to the required size.

[0024] In practice, the clamp 300 is made of carbon steel and includes an upper half-ring clamp 304 and a lower half-ring clamp 301. The ends of the upper half-ring clamp 304 and the lower half-ring clamp 301 are fixedly connected by bolts 600.

[0025] Specifically, the lower half ring hoop 301 has thickened parts 302 at both ends, and threaded holes 303 are provided on the thickened parts 302. The upper half ring hoop 304 has a through hole 305 at its end, and one end of the bolt 600 passes through the through hole 305 and is threadedly connected to the threaded hole 303.

[0026] When using, such as Figure 4 As shown, after aligning the end cap 200, sealing gasket 400 and flange 101, insert the pin 202 into the pin hole 102, then align the clamping blocks 500 on the upper half ring 304 and lower half ring 301 and clamp them onto the circumference of the flange 101 and the round edge 201, and then tighten the bolts 600 to complete the assembly, which is very convenient and quick.

[0027] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
