Description

Technical Field

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

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.

[0003] Existing heat exchangers are assembled in a relatively integrated manner, which is not only difficult to disassemble and clean, but also has relatively fixed connections between structures. This requires forced disassembly for internal structural inspection. Therefore, those skilled in the art have provided a heat exchanger that is easy to clean to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a heat exchanger that is easy to clean, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat exchanger that is easy to clean, comprising two protective shells, with multiple heat exchange tubes tightly fitted between the two protective shells, rectangular boxes being snapped onto both sides of the two protective shells, and two screws being symmetrically threaded through the top and bottom of the two rectangular boxes, with both ends of the multiple heat exchange tubes passing through the two rectangular boxes, and nuts being threaded onto the outer walls of the multiple screws.

[0006] As a further improvement of this utility model: both the top and bottom of the two protective shells are fixedly connected with locking blocks, and the top inner wall and bottom inner wall of the two rectangular boxes are symmetrically provided with two locking slots, and the multiple locking slots are respectively connected to the multiple locking blocks through each other.

[0007] As a further improvement of this utility model: multiple rectangular grooves are vertically arranged on the inner walls of the two opposite sides of the rectangular boxes, and the two protective shells are engaged in the multiple rectangular grooves on the opposite sides.

[0008] As a further embodiment of this utility model: trapezoidal blocks are fixedly connected to the top and bottom of the two rectangular boxes, and multiple screws are threadedly connected to the multiple trapezoidal blocks respectively. The multiple screws are all arranged horizontally, and the inner sides of the multiple nuts are respectively attached to the outer sides of the two trapezoidal blocks on one side.

[0009] As a further improvement of this utility model: multiple through holes are vertically arranged on one side of both rectangular boxes, and the two ends of the multiple heat exchange tubes pass through the multiple through holes on both sides respectively.

[0010] As a further improvement of this utility model: rectangular blocks are fixedly connected to the sides of the multiple heat exchange tubes that are close to each other, and the opposite sides of the two protective shells are attached to the sides of the multiple rectangular blocks.

[0011] As a further improvement of this utility model: both sides of the two rectangular boxes are fixedly connected with support legs, and the inner walls of the opposite sides of the two trapezoidal blocks are tightly fitted to the two sides of the two protective shells.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] After removing the nuts from the screws, the screws can be rotated to remove them laterally from the trapezoidal block, which will release the two rectangular boxes from their fixation. Then, pull the two rectangular boxes to the sides, which will disengage the multiple slots from the multiple clips, allowing the two rectangular boxes to be removed from the sides of the protective shell. This will completely release the fixation on the multiple heat exchange tubes.

[0014] This utility model is simple to use. Multiple heat exchange tubes are connected and fixed by rectangular blocks. Multiple rectangular boxes are fixed to the protective shell by tenon and thread, which not only makes disassembly simple but also makes the fixation firm, thus facilitating the inspection and cleaning of the internal structure. In addition, the multiple structures are fixed by separate connection, which facilitates separate processing. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 In this embodiment of the utility model, a heat exchanger that is easy to clean includes two protective shells 1, with multiple heat exchange tubes 2 tightly fitted between the two protective shells 1. Rectangular boxes 5 are snapped onto both sides of the two protective shells 1, and two screws 4 are symmetrically threaded through the top and bottom of the two rectangular boxes 5. Both ends of the multiple heat exchange tubes 2 pass through the two rectangular boxes 5, and nuts 8 are threaded onto the outer walls of the multiple screws 4.

[0023] In this embodiment, the top and bottom of the two protective shells 1 are fixedly connected with the locking blocks 11, and the top inner wall and bottom inner wall of the two rectangular boxes 5 are symmetrically provided with two locking slots 7, and the multiple locking slots 7 are respectively connected to the multiple locking blocks 11 through the penetration.

[0024] In this embodiment, multiple rectangular slots 10 are vertically arranged on the inner walls of the two opposite sides of the two rectangular boxes 5, and the two protective shells 1 are engaged in the multiple rectangular slots 10 on the opposite sides.

[0025] In this embodiment, trapezoidal blocks 3 are fixedly connected to the top and bottom of the two rectangular boxes 5, and multiple screws 4 are threadedly connected to the multiple trapezoidal blocks 3 respectively. The multiple screws 4 are all arranged horizontally, and the inner side of the multiple nuts 8 is respectively attached to the outer side of the two trapezoidal blocks 3 on one side.

[0026] In this embodiment, multiple through holes 12 are vertically arranged on one side of each of the two rectangular boxes 5, and the two ends of the multiple heat exchange tubes 2 pass through the multiple through holes 12 on both sides respectively.

[0027] In this embodiment, rectangular blocks 9 are fixedly connected to the sides of the multiple heat exchange tubes 2 that are close to each other, and the opposite sides of the two protective shells 1 are attached to the sides of the multiple rectangular blocks 9.

[0028] In this embodiment, two rectangular boxes 5 are fixedly connected to two sides with support legs 6, and the inner walls of the opposite sides of the two trapezoidal blocks 3 are tightly fitted to the two sides of the two protective shells 1. The two rectangular grooves 10 can be engaged with the outer side of the protective shell 1 during installation, thereby enhancing the stability of the engagement. The multiple support legs 6 provide support for the two rectangular boxes 5.

[0029] The working principle of this utility model is as follows: After rotating multiple nuts 8 to remove them from screws 4, multiple screws 4 can be rotated to remove them laterally from trapezoidal blocks 3. At this time, the fixation on the two rectangular boxes 5 will be released. Then, the two rectangular boxes 5 are pulled to both sides, which can disengage multiple slots 7 from multiple locking blocks 11. Thus, the two rectangular boxes 5 can be removed from both sides of the protective shell 1. At this time, the fixation on multiple heat exchange tubes 2 will be completely released. Then, the removed components can be inspected and cleaned.
