Description

Technical Field

[0001] This utility model relates to the field of heat exchanger manufacturing technology, specifically a heat exchanger tube bundle insertion device. Background Technology

[0002] Heat exchangers are used for heating materials, recovering waste heat, and are widely used in various industrial fields. There are many types of heat exchangers, among which shell-and-tube heat exchangers are commonly used. These heat exchangers generally consist of a cylindrical shell, inside which are arranged multiple tube bundles and multiple tube bundles with good thermal conductivity. These tube bundles pass through the tube bundles and are fixed to the tube bundles. During assembly, the tube bundles need to be inserted into the tube bundles from one end of the shell. To ensure the stability of the tube bundles, the fit clearance between the tube bundles and the tube bundles is small.

[0003] Existing patent CN212705389U discloses a tube-threading device for assembling heat exchanger tube bundles, including a support guide rail, on which a traction seat, a positioning seat, and a tube bundle support seat are sequentially arranged. The traction seat is connected to a drive mechanism and has a detachable positioning plate. The positioning seat has a detachable housing, inside which multiple support plates and multiple traction rods are arranged. The diameter of the traction rods is smaller than the outer diameter of the heat exchanger tube bundle. This device can assemble all tube bundles in one operation.

[0004] However, the tube insertion device still has some defects. During use, the tube bundle is pulled by a traction rod. However, the traction rod is relatively long and is prone to bending due to gravity, which makes it impossible for the traction rod to pass through the shell. In addition, the tube bundle is pre-supported by the support through hole inside the support column. However, the inner diameter of the support through hole is similar to the diameter of the tube bundle, which makes the operation of inserting the tube bundle more cumbersome.

[0005] Based on this, a heat exchanger tube bundle insertion device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a heat exchanger tube bundle insertion device to solve the problems of cumbersome operation and poor insertion effect in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A heat exchanger tube bundle insertion device includes a base plate. Two first electric slide rails are installed on the top right sides of the base plate, and a first slider is slidably connected inside the first electric slide rails. Two second electric slide rails are installed in the middle of the top right side of the base plate, and a second slider is slidably connected inside the second electric slide rails.

[0009] A support assembly is installed on the top left side of the base plate;

[0010] A guide assembly is installed on the top of the first slider. The guide assembly includes a fixing plate. The fixing plate is installed on the top of the first slider. A support frame is installed in the middle of the top of the fixing plate. A support tube is installed inside the support frame. A guide tube is installed on the right side of the support tube. A silicone layer is installed on the left side of the support tube.

[0011] A lubrication assembly is installed on the top left side of the fixing plate;

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model supports the outer shell through a support component, which facilitates the rotation of the outer shell to adjust its angle. The guide component and lubrication component work together to facilitate the insertion of the tube bundle into the internal hole of the support tube for support. The inner diameter of the internal hole of the guide tube is smaller on the left and larger on the right, which facilitates the guidance of the inserted tube bundle into the support tube for support. The lubrication component lubricates the tube bundle, improving the practicality and convenience of the device.

[0023] 2. This utility model facilitates the pushing of the tube bundle inside the support tube by using the fixed component and the pushing component together, so that the tube bundle can be inserted into the shell. The operation of the electric push rod causes the push rod to move the silicone head, thereby pushing the tail end of the tube bundle out of the support tube and into the shell, which improves the convenience and practicality of the device.

[0035] In this embodiment, the operation of the first electric slide rail 11 drives the first slider 12 inside it to move, thereby driving the guide assembly to move. The operation of the second electric slide rail 13 drives the second slider 14 to move, causing the fixing assembly to move. The fixing plate 2 supports the support frame 21, the support frame 21 supports the support tube 22, the guide tube 23 on one side of the support tube 22 guides the tube bundle, and the silicone layer 24 adheres to the tube bundle to achieve a certain friction and anti-slip effect.

[0036] In one embodiment, such as Figure 1 and Figure 3 As shown, the support assembly includes a support plate 15, which is installed on the top left side of the base plate 1. A drive roller 16 is installed on the left side of the support plate 15, and a support roller 17 is installed on the top right side of the support plate 15. A housing 18 is placed on top of the support roller 17 and the drive roller 16. The support plate 15 supports the drive roller 16 and the support roller 17, and the drive roller 16 and the support roller 17 support the housing 18. The operation of the drive roller 16 drives the housing 18 to rotate and adjust its angle.

[0037] In one embodiment, such as Figure 1 and Figure 2 As shown, a limiting component is installed on the left side of the base plate 1 to limit the tube bundle.

[0038] In one embodiment, such as Figure 1 Figure 2As shown, the limiting component includes a side plate 19, which is installed on the left side of the base plate 1. A buffer plate 110 is installed on one side of the side plate 19. The buffer plate 110 on one side of the side plate 19 limits the tube bundle and prevents the tube bundle from falling off the left side of the outer shell 18.

[0039] In one embodiment, such as Figure 1 and Figure 3 As shown, the lubrication assembly includes a storage tank 25, which is installed on the top left side of the fixed plate 2.

A push rod 36 is installed on one side of the push plate 35, and a silicone head 37 is installed on one side of the push rod 36. The operation of the electric push rod 34 drives the push plate 35 to move, thereby causing the silicone head 37 on one side of the push rod 36 to enter the interior of the support tube 22, thereby pushing the tube bundle into the outer shell 18.

[0043] The above embodiment discloses a heat exchanger tube bundle insertion device. The outer shell 18 is placed on top of the drive roller 16 and the support roller 17. The drive roller 16 rotates the outer shell 18, facilitating angle adjustment and improving device convenience.

The silicone layer 24 on the left side of the support tube 22 adheres to the outer side of the tube bundle, providing damping and anti-slip effects. Simultaneously with tube bundle insertion, the pump 26 draws lubricant from the storage tank 25 and sends it into the outlet ring 27. The lubricant is atomized and sprayed onto the tube bundle through the atomizing nozzle 28 inside the outlet ring 27, facilitating insertion of the tube bundle into the support tube 22 and improving device convenience. The device offers convenience and practicality. The operation of the first electric slide rail 11 moves the support tube 22 and its internal tube bundle to one side of the outer shell 18.
