Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, specifically a heat exchanger that is easy to assemble. Background Technology

[0002] In the field of heat exchanger manufacturing and maintenance, the traditional connection between the shell and the cover usually relies on bolts. Although this connection method is relatively stable in structure, it has some significant inconveniences in the assembly and disassembly process. The traditional connection method requires operators to pick up and position the bolts one by one during assembly, which is not only time-consuming and laborious, but also easy to lose or be difficult to align accurately in confined spaces or complex operating environments, which increases the difficulty of maintenance and repair. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a heat exchanger that is easy to assemble. It solves the problem that the traditional connection method requires operators to pick up and position the bolts one by one during assembly, which is not only time-consuming and laborious, but also easy to lose or be difficult to align accurately in small spaces or complex operating environments, which increases the difficulty of maintenance and repair.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger that is easy to assemble, comprising a shell, wherein a plurality of clamping blocks are fixedly connected to the outer wall of the shell, and a rotating shaft is rotatably connected between corresponding two clamping blocks. One end of the rotating shaft is fixedly connected to a bolt, and a baffle is fixedly connected to the end of the bolt away from the rotating shaft. A pressure plate is threadedly connected to the outer wall of the bolt. A first connecting member is fixedly installed on one side of the outer wall of the shell on the clamping block. A shell cover is provided on one side of the shell, and a second connecting member is fixedly connected to one side of the shell cover. Both the first connecting member and the second connecting member have slots corresponding to the bolts. The bolts pass through the slots, and the first connecting member and the second connecting member are fixed together by bolts and pressure plates.

[0005] As a further embodiment of this utility model: a bracket is fixedly connected to the lower part of the housing, a base is provided below the bracket, and several fixing blocks are fixedly installed on both sides of the bracket and the base respectively.

[0006] As a further embodiment of this utility model: the fixing blocks on both sides of the bracket correspond to the fixing blocks on both sides of the base, and a support column is provided between the two corresponding fixing blocks. A compression spring is sleeved on the outer wall of the support column between the two corresponding fixing blocks.

[0007] As a further embodiment of this utility model: an output motor is provided on one side of the base, and a rotating rod is provided at the output end of the output motor, the rotating rod passing through the base.

[0008] As a further embodiment of this utility model: the outer wall of the rotating rod is fixedly connected with a protrusion, and the number of the protrusions is two.

[0009] As a further embodiment of this utility model: a reserved groove is provided on the upper part of the base, and the position of the reserved groove corresponds to the position of the protrusion.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This easily assembled heat exchanger, by setting up clamping blocks, a rotating shaft, bolts, a pressure plate, a first connecting piece, and empty slots, allows for easy assembly of the shell and cover. Rotating the bolts causes them to rotate between corresponding clamping blocks via the rotating shaft, positioning them in the empty slots of the first and second connecting pieces. Rotating the pressure plate, which is threaded to the bolts, causes it to continuously tighten and compress the second connecting piece on the outer wall of the bolts. This results in the second connecting piece causing the cover to fit against one side of the shell and the first connecting piece, facilitating the assembly of the shell and cover. This method eliminates the traditional method of requiring operators to manually pick up and position each bolt during assembly, reducing the need for manual bolt positioning and saving time and effort, thus simplifying the assembly of the shell and cover.

[0012] 2. This easily assembled heat exchanger, by setting a fixed block, support column, compression spring, rotating rod, protrusion, and reserved groove, allows the output motor to be started during use. The output motor drives the rotating rod to rotate, which in turn drives the protrusion to rotate. As the protrusion rotates, it passes through the reserved groove and continuously strikes the bottom of the support column. This causes the support column and the shell to vibrate by squeezing the compression spring against the outer wall of the support column through the fixed block. This vibration reduces and delays the formation of scale, thereby improving the service life of the heat exchanger. Attached Figure Description

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a heat exchanger that is easy to assemble, including a shell 1. Several clamping blocks 2 are fixedly connected to the outer wall of the shell 1. A rotating shaft 3 is rotatably connected between corresponding pairs of clamping blocks 2. A bolt 4 is fixedly connected to one end of the rotating shaft 3, and a baffle 5 is fixedly connected to the end of the bolt 4 away from the rotating shaft 3. Because of the baffle 5, the baffle 5 limits the pressure plate 6 at the end of the bolt 4, preventing the pressure plate 6 from rotating too much and detaching from the bolt 4, thus avoiding loss. The outer wall of the bolt 4 is threaded with the pressure plate 6. The connection between the bolt 4 and the pressure plate 6... When the pressure plate 6 rotates and tightens the second connecting piece 9 on the outer wall of the bolt 4, the shell cover 8 is fixed to one side of the shell 1 by fixing the second connecting piece 9, which facilitates the assembly of the shell 1 and the shell cover 8. The outer wall of the shell 1 is fixedly installed on one side of the clamping block 2. The shell cover 8 is provided on one side of the shell 1. The second connecting piece 9 is fixedly connected to one side of the shell cover 8. The first connecting piece 7 and the second connecting piece 9 are both provided with slots 10 at the positions corresponding to the bolt 4. The bolt 4 passes through the slots 10. The first connecting piece 7 and the second connecting piece 9 are fixed together by the bolt 4 and the pressure plate 6.

[0019] A bracket 11 is fixedly connected to the lower part of the housing 1. A base 12 is located below the bracket 11. Several fixing blocks 13 are fixedly installed on both sides of the bracket 11 and the base 12. The fixing blocks 13 on both sides of the bracket 11 correspond to the fixing blocks 13 on both sides of the base 12. A support column 14 is provided between two corresponding fixing blocks 13. A compression spring 15 is sleeved on the outer wall of the support column 14 between the two corresponding fixing blocks 13. Because of the compression spring 15, the bracket 11 compresses the compression spring 15 on the outer wall of the support column 14 through the fixing blocks 13. The compression spring 15 rebounds and causes the housing 1 to vibrate through the bracket 11. Vibration can reduce and delay the formation of scale. The base 12... An output motor 16 is provided on one side, and a rotating rod 17 is provided at the output end of the output motor 16. The rotating rod 17 passes through the base 12, and a protrusion 18 is fixedly connected to the outer wall of the rotating rod 17. Because of the protrusion 18, the output motor 16 drives the protrusion 18 to rotate under the bracket 11 through the rotating rod 17 and continuously strike the bracket 11, causing the bracket 11 to drive the housing 1 to vibrate continuously, reducing the workload of the operator. There are two protrusions 18. A reserved slot 19 is provided on the top of the base 12. The position of the reserved slot 19 corresponds to the position of the protrusion 18. Because of the reserved slot 19, the reserved slot 19 provides enough space for the protrusion 18 to rotate and strike the bottom of the bracket 11, optimizing the use of space.

[0020] The working principle of this utility model is as follows: When assembling the shell 1 and the shell cover 8, align the second connecting piece 9 on the shell cover 8 with the slot 10 of the first connecting piece 7 on the shell 1. Rotate the bolt 4, and the bolt 4 will rotate between the two corresponding clamping blocks 2 through the rotating shaft 3 into the slot 10 of the first connecting piece 7 and the second connecting piece 9. Then rotate the pressure plate 6, and the pressure plate 6 will rotate on the outer wall of the bolt 4 to continuously tighten and squeeze the second connecting piece 9, thus fastening the second connecting piece 9 to one side of the first connecting piece 7, so that the shell 1 and the shell cover 8 can be assembled and connected. During the use of this heat exchanger, start the output motor 16, and the output motor 16 will drive the protrusion 18 to rotate through the rotating rod 17. When the protrusion 18 reaches the appropriate position, it will pass through the reserved slot 19 and strike the bottom of the bracket 11, so that the bracket 11 will drive the shell 1 to slide and squeeze the compression spring 15 on the outer wall of the support column 14 through the fixing block 13. The compression spring 15 will be squeezed and rebound, causing the shell 1 to vibrate. The vibration will reduce and delay the formation of scale.
