Description

Technical Field

[0001] This utility model belongs to the technical field of plate and shell heat exchangers, and in particular relates to a detachable fully welded plate and shell heat exchanger. Background Technology

[0002] All-welded plate heat exchangers are a type of efficient and compact heat exchange equipment. Existing all-welded plate heat exchangers typically enclose the heat exchange core with side plates and are fixed with a large number of bolts. When the heat exchanger needs to be disassembled, the side plates need to be removed. However, due to the large number of bolts, the disassembly process is cumbersome and inefficient, requiring multiple workers to work together. Therefore, we propose a detachable all-welded plate heat exchanger. Utility Model Content

[0003] The purpose of this utility model is to provide a detachable fully welded plate-shell heat exchanger. After the side plate is placed on the side of the heat exchange core, the insert rod is inserted into the two fixing blocks, and then the locking nut is used to lock it in place, thus completing the installation of the side plate. When disassembly is required, the locking nut on the insert rod is removed, the insert rod is pulled out, and then the side plate is pulled out for disassembly. This method does not require multiple people to disassemble a large number of bolts, making disassembly simpler, more convenient, and more efficient. It solves the problem that existing fully welded plate-shell heat exchangers require the side plate to be disassembled when disassembly is needed, but due to the large number of bolts installed, the disassembly operation is cumbersome and inefficient, requiring multiple workers to cooperate in the disassembly.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a detachable, fully welded plate-shell heat exchanger, comprising a heat exchanger body, which includes a support base. Support legs are fixedly connected to the four corners of the bottom of the support base. A heat exchange core is fixedly connected to the top of the support base via bolts. Side plates are provided on both the front and back of the heat exchange core. Several mounting columns are fixedly connected to the outer sides of the side plates. Fixing blocks are fixedly connected to the top and bottom of each mounting column. Each fixing block has an insertion hole inside, into which a rod is inserted. The rod has threads on its outer side, and a locking nut is threaded onto the threads of the rod. A sealing gasket is provided on the side of the side plate facing the heat exchange core. The mounting columns are fixed to the side plates by welding, and the rods are used to simultaneously insert into the fixing blocks on both sides, facilitating subsequent installation and fixation of the side plates.

[0006] Furthermore, a support assembly is provided at the bottom of the side panel. The support assembly includes a fixed frame fixedly connected to the support leg. Two support plates are fixedly connected to the bottom of the fixed frame. The top of the support plates contacts the bottom of the side panel. The support plates are used to support the side panel during installation, making it easier for workers to install the side panel.

[0007] Furthermore, two positioning blocks are fixedly connected to the side of the mounting column facing the side plate. The two positioning blocks are respectively distributed at the top and bottom of the side plate. Four square grooves are opened inside the side plate. Four inserts that cooperate with the square grooves are fixedly connected to the side of the sealing gasket facing the side plate. The top of the inserts is provided with an inclined groove. The inserts are used to position the installation of the sealing gasket and facilitate the subsequent pressing and fixing of the sealing gasket to the side plate.

[0008] Furthermore, an extrusion assembly is provided on the outer side of the side plate. The extrusion assembly includes an extrusion rod, a limit ring is fixedly connected to the top of the extrusion rod, a support block is provided above the extrusion rod, the side of the support block facing the side plate is fixedly connected to the surface of the side plate, a threaded rod is threadedly connected inside the support block, and a throttle is fixedly connected to the top of the threaded rod. The limit ring, through cooperation with the limit convex shaft, enables the threaded rod to smoothly push and pull the extrusion rod.

[0009] Furthermore, a limiting convex shaft is fixedly connected to the bottom of the threaded rod, and the limiting convex shaft is rotatably connected to the limiting ring. The threaded rod is rotatably connected to the limiting ring through the limiting convex shaft. The outer surface of the extrusion rod is slidably limited to the surface of the side plate. The extrusion rod is adapted to the inclined groove. After the extrusion rod enters the inclined groove, it will push the insert block under the action of the inclined surface.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model uses an installation column. Specifically, after the side plate is placed on the side of the heat exchange core, the insertion rod is inserted into two fixing blocks and then locked with a locking nut to complete the installation of the side plate. When disassembly is required, the locking nut on the insertion rod is removed, the insertion rod is pulled out, and then the side plate is pulled out for disassembly. This method does not require multiple people to disassemble a large number of bolts, making disassembly simpler, more convenient, and more efficient.

[0012] 2. This utility model uses a compression assembly. Specifically, the sealing gasket is inserted into the square groove on the side plate via an insert block. Then, the handle is turned clockwise to move the threaded rod downward, causing the compression rod to enter the inclined groove and push the insert block, thus making the sealing gasket fit tightly against the side plate to complete the installation. By turning the handle counterclockwise, the compression rod is moved upward and away from the inclined groove, thereby releasing the sealing gasket from its fixation, which facilitates subsequent replacement or maintenance. The operation is simple and convenient.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] Please see Figures 1-5As shown, this utility model is a detachable fully welded plate-shell heat exchanger, including a heat exchanger body 1. The heat exchanger body 1 includes a support base 2. Support legs 21 are fixedly connected to the four corners of the bottom of the support base 2. A heat exchange core 11 is fixedly connected to the top of the support base 2 by bolts. Side plates 12 are provided on the front and back of the heat exchange core 11. Several mounting columns 13 are fixedly connected to the outer side of the side plates 12. Fixing blocks 131 are fixedly connected to the top and bottom of the mounting columns 13. Insertion holes are opened inside the fixing blocks 131, and insertion rods 132 are inserted into the insertion holes. The outer side of the insertion rods 132 is provided with... The insert rod 132 has threads, and a locking nut is threaded onto the outer thread. A sealing gasket 121 is provided on the side of the side plate 12 facing the heat exchange core 11. After the side plate 12 is placed on the side of the heat exchange core 11, the insert rod 132 is inserted into the two fixing blocks 131 and then locked with the locking nut to complete the installation of the side plate 12. When disassembly is required, the locking nut on the insert rod 132 is removed, the insert rod 132 is pulled out, and then the side plate 12 is pulled out for disassembly. This method does not require multiple people to disassemble a large number of bolts, making disassembly simpler, more convenient, and more efficient.

[0024] A support assembly 14 is provided at the bottom of the side plate 12. The support assembly 14 includes a fixed frame 141 fixedly connected to the support leg 21. Two support plates 142 are fixedly connected to the bottom of the fixed frame 141. The top of the support plate 142 contacts the bottom of the side plate 12.

[0025] The mounting post 13 is fixedly connected to two positioning blocks 133 on the side facing the side plate 12. The two positioning blocks 133 are respectively distributed on the top and bottom of the side plate 12. The side plate 12 has four square grooves. The sealing gasket 121 is fixedly connected to four inserts 211 that are positioned and matched with the square grooves on the side facing the side plate 12. The top of the inserts 211 has a slanted groove 212.

[0026] An extrusion assembly 15 is provided on the outer side of the side plate 12. The extrusion assembly 15 includes an extrusion rod 151. A limit ring 152 is fixedly connected to the top of the extrusion rod 151. A support block 153 is provided above the extrusion rod 151. The side of the support block 153 facing the side plate 12 is fixedly connected to the surface of the side plate 12. A threaded rod 154 is threadedly connected inside the support block 153. A handle 155 is fixedly connected to the top of the threaded rod 154. The sealing gasket 121 is inserted into the square groove on the side plate 12 through the insert block 211. Then, the handle 155 is rotated clockwise to drive the threaded rod 154 downward, so that the extrusion rod 151 enters the inclined groove 212 and pushes the insert block 211, so that the sealing gasket 121 is tightly attached to the side plate 12 to complete the installation. By rotating the handle 155 counterclockwise, the extrusion rod 151 is moved upward and away from the inclined groove 212, thereby releasing the fixing of the sealing gasket 121, which is convenient for subsequent replacement or maintenance. The operation is simple and convenient.

[0027] The bottom of the threaded rod 154 is fixedly connected to the limiting cam 156, which is rotatably connected to the limiting ring 152.

The outer surface of the extrusion rod 151 is slidably limited to the surface of the side plate 12, and the extrusion rod 151 is adapted to the inclined groove 212.

[0028] One specific application of this embodiment is:

[0029] In use, the heat exchange core 11 is fixed to the top of the support base 2 with bolts. Then, the sealing gasket 121 is inserted into the square groove on the side plate 12 through the insert block 211. Then, the handle 155 is turned clockwise to drive the threaded rod 154 to move downward. The threaded rod 154, through the connection of the limiting cam 156 and the limiting ring 152, drives the extrusion rod 151 to move downward. Since the extrusion rod 151 is in contact with the surface of the side plate 12, the extrusion rod 151 will move in a straight line. When the extrusion rod 151 enters the inclined groove 212, it will push the insert block through the inclined surface of the inclined groove 212. When 211 is pushed, the insert block 211 will drive the sealing gasket 121 to move together, so that the sealing gasket 121 is in close contact with the side plate 12. Then the side plate 12 is placed on the support plate 142, and the sealing gasket 121 is in contact with the side of the heat exchange core 11. After the side plates 12 are placed on both sides of the heat exchange core 11, the insert rod 132 is inserted into the two fixing blocks 131. Then the locking nut is installed on the threaded part of the insert rod 132 and locked. At this time, the side plate 12 is installed, and the sealing gasket 121 is squeezed by the locking, which plays a sealing role.

[0030] When the heat exchange core 11 needs to be disassembled, remove the locking nut on the insert rod 132 and pull out the insert rod 132. Then pull out the side plate 12 to disassemble it. When the sealing gasket 121 needs to be replaced, turn the handle 155 counterclockwise to drive the threaded rod 154 upward, which will pull the extrusion rod 151 upward and away from the inclined groove 212, thereby releasing the fixing of the sealing gasket 121. Finally, pull out the sealing gasket 121 to replace it.
