Currently, the length of the shell and tube heat exchanger operating in industrial production is several meters or even more than ten meters. Long-term operation will cause the heat exchange tubes to be blocked by water scale, which will reduce the heat exchange efficiency, increase energy consumption, and shorten the service life. If the water scale cannot be cleaned in time, there will be risks of equipment maintenance, shutdown, or scrapping.

[0022] The present utility model provides a shell-and-tube heat exchanger, which includes a heat exchanger body 101, a fixed box 102 and a protection assembly. The protection assembly includes a fixed block 103, an adjustment disk 104, an adjustment rod 105, a sliding plate 106, two limiting rods 107, two groups of lifting members, a bearing member, an arc-shaped plate 108, two clamping blocks 109 and two groups of protection members.

The foregoing solution solves the problem that the heat exchanger does not have protection, is easily affected by surrounding foreign objects, and is likely to cause the tank body to be damaged if impacted by foreign objects, affecting the normal operation of the heat exchanger.

[0023] For this specific embodiment, the fixed box 102 is detachably connected to the heat exchanger body 101 and is located below the heat exchanger body 101. The protection assembly includes a fixed block 103, an adjustment disc 104, an adjustment rod 105, a sliding plate 106, two limiting rods 107, two groups of lifting members, a bearing member, an arc-shaped plate 108, two clamping blocks 109, and two groups of protection members. The fixed block 103 is fixedly connected to the fixed box 102 and is located inside the fixed box 102. The adjustment disc 104 is fixedly connected to one end of the adjustment rod 105 and is located outside the fixed box 102. The other end of the adjustment rod 105 is rotatably connected to the fixed block 103 and is located inside the fixed box 102, and the surface of the adjustment rod 105 has threads. The sliding plate 106 is threadedly connected to the adjustment rod 105 and is located outside the adjustment rod 105, and the adjustment rod 105 penetrates through the sliding plate 106. The two limiting rods 107 are fixedly connected to the fixed box 102 and penetrate through the sliding plate 106. The two groups of lifting members are symmetrically arranged. The lifting member is fixedly connected to the sliding plate 106 and is located above the fixed box 102. The bearing member is fixedly connected to the lifting member and is located above the lifting member. The arc-shaped plate 108 is detachably connected to the heat exchanger body 101 and is located below the heat exchanger body 101. The two clamping blocks 109 are fixedly connected to the arc-shaped plate 108 and are located below the arc-shaped plate 108. The two groups of protection members are symmetrically arranged. The protection member is fixedly connected to the arc-shaped plate 108 and is located outside the arc-shaped plate 108. The fixed box 102 is moved below the heat exchanger body 101. The arc-shaped plate 108 is sleeved below the heat exchanger body 101. The clamping block 109 and the bearing member are fixed by bolts, so that the arc-shaped plate 108 is fixed above the bearing member. The adjustment disc 104 drives the adjustment rod 105 to rotate. The adjustment rod 105 rotates outside the fixed block 103. The limiting rod 107 prevents the sliding block from shifting. The sliding block pushes the lifting member upward. The bearing member fits the arc-shaped plate 108 to the heat exchanger body 101. The protection member provides a buffer when the heat exchanger body 101 is impacted by foreign objects, reducing the impact force. In this way, the problem that the heat exchanger is not protected and is easily affected by surrounding foreign objects can be effectively solved.

[0024] Among them, the moving seat 110 is fixedly connected to the sliding plate 106 and is located above the sliding plate 106. The first rotating rod 111 is rotatably connected to the moving seat 110 and is located above the moving seat 110. The connecting rod 112 is rotatably connected to the first rotating rod 111 and penetrates through the first rotating rod 111. The sliding plate 106 drives the moving seat 110 to move. The first rotating rod 111 rotates around the connecting rod 112.

[0025] Secondly, the fixed seat 113 is fixedly connected to the fixed box 102 and is located above the fixed box 102. The second rotating rod 114 is rotatably connected to the fixed seat 113 and is located above the fixed seat 113. Moreover, the connecting rod 112 penetrates through the second rotating rod 114. The second rotating rod 114 rotates on the outside of the fixed seat 113, and the second rotating rod 114 rotates around the connecting rod 112, thereby pushing the bearing member upward.

[0026] Meanwhile, the support plate 115 is rotatably connected to the first rotating rod 111 and is located above the first rotating rod 111. The bearing block 116 is fixedly connected to the support plate 115 and is located above the support plate 115. The first rotating rod 111 and the second rotating rod 114 cooperate to push the support plate 115 upward. The bearing block 116 bears the arc-shaped plate 108, and through the upward movement of the support plate 115, the arc-shaped plate 108 is made to fit the heat exchanger body 101, so as to facilitate protecting it according to the installation height of the heat exchanger body 101.

[0027] In addition, two first dampers 117 are fixedly connected to the arc-shaped plate 108 and are located outside the arc-shaped plate 108. The protection plate 118 is fixedly connected to the two first dampers 117 and is located outside the first dampers 117. When an external object impacts the protection plate 118, the first dampers 117 buffer and offset the impact force, thereby preventing the external object from damaging the heat exchanger body 101.

[0028] When using a shell-and-tube heat exchanger of this embodiment, by setting the fixed box 102 and the protection assembly, during specific use, the fixed box 102 is moved to the lower part of the heat exchanger body 101, the arc-shaped plate 108 is sleeved on the lower part of the heat exchanger body 101, and the clamping block 109 is fixed to the bearing block 116 through bolts, so as to fix the arc-shaped plate 108 above the support plate 115. The adjusting disc 104 drives the adjusting rod 105 to rotate, the sliding block drives the moving seat 110 to move, the first rotating rod 111 rotates around the connecting rod 112, the second rotating rod 114 rotates around the connecting rod 112, thereby pushing the support plate 115 upward, and thus pushing the arc-shaped plate 108 upward to make the arc-shaped plate 108 fit the outside of the heat exchanger body 101. When the heat exchanger body 101 is impacted by a foreign object, the protection plate 118 cooperates with the first dampers 117 to buffer and offset the impact force, so as to effectively protect the heat exchanger and provide buffer protection when the heat exchanger is impacted by an external object, improving the protection performance of the heat exchanger.

[0029] The second embodiment of the present application is as follows:

[0030] Based on the first embodiment, please refer to Figure 4 , Figure 4 which is a schematic structural diagram of the second embodiment of the present utility model.

[0031] The present utility model provides a shell and tube heat exchanger which further includes an auxiliary component. The auxiliary component includes an upper top plate 201, two dampers II 202 and an upper guard plate 203.

[0032] For this specific embodiment, the upper top plate 201 is detachably connected to the arc-shaped plate 108 and is located above the heat exchanger body 101. The two dampers II 202 are fixedly connected to the upper top plate 201 and are located above the upper top plate 201. The upper guard plate 203 is fixedly connected to the two dampers II 202 and is located above the dampers II 202. The upper top plate 201 is fixed above the arc-shaped plate 108 by bolts, so as to fit with the heat exchanger body 101. The upper guard plate 203 protects the heat exchanger body 101 from being damaged by falling objects from a height, and the damper II 202 provides buffering when the upper guard plate 203 is hit by a falling object.

[0033] When using the shell and tube heat exchanger of this embodiment, by setting the auxiliary component, during specific use, the upper top plate 201 is fixed above the arc-shaped plate 108 by bolts, so as to fit with the heat exchanger body 101. The upper guard plate 203 protects the heat exchanger body 101 from being damaged by falling objects from a height, and the damper II 202 provides buffering when the upper guard plate 203 is hit by a falling object.
