Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger production, in particular to a tube plate supporting mechanism for installing heat exchange tubes of a heat exchanger. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers part of the heat of a hot fluid to a cold fluid. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes.

[0003] The heat exchanger is mainly composed of an outer shell, heat exchange tubes and tube sheets used to fix the heat exchange tubes. The tube sheets mainly support and limit the heat exchange tubes and connect them to the outer shell. During the production process, the tube sheets need to be fixed vertically first, and then the heat exchange tubes are inserted into the mounting holes in the tube sheets. During this process, the tube sheets need to be clamped in a fixed position. The existing clamping equipment lacks the necessary support, resulting in a certain tilt when the pipes are inserted. The tilted tube sheets are prone to friction with the heat exchange pipes, which is not conducive to the pipe insertion work. Utility Model Content

[0004] The utility model aims at the defects in the prior art and provides a tube sheet supporting mechanism for installing heat exchange tubes of a heat exchanger.

[0005] The utility model is achieved through the following technical solutions:

[0006] A tube sheet support mechanism for installing heat exchange tubes of a heat exchanger, comprising a support base, a guide rod, a plug-in plate mechanism and a blocking mechanism. The guide rod is fixedly arranged on the inner side of the support base, the plug-in plate mechanism is sleeved on the outside of the guide rod, and the blocking mechanism is arranged on the back of the plug-in plate mechanism. The plug-in plate mechanism comprises a plug-in plate seat, a guide tube, a locking knob and a clamping knob. The guide tube is fixedly arranged on the outer bottom of the plug-in plate seat, the locking knob is threadedly connected to the guide tube, and the clamping knob is connected to one side of the plug-in plate seat.

[0007] In a preferred embodiment of the present invention, the blocking mechanism includes a connecting plate, a mounting tube, a screw and a blocking bar, wherein the mounting tube is fixedly arranged on the top of the outer side of the connecting plate, the screw is clamped inside the mounting tube, and the blocking bar is fixedly arranged on the top of the screw;

[0008] The blocking mechanism provides effective support behind the tube sheet to prevent the tube sheet from tilting during the insertion of the heat exchange tubes, thereby affecting the tube insertion operation.

[0009] In a preferred embodiment of the present invention, the guide tube is sleeved on the outside of the guide rod, and a locking groove is provided on the top of the guide rod to cooperate with the locking knob;

[0010] The sliding of the guide tube on the surface of the guide rod changes the fixed position of the tube plate, and the locking groove on the top of the guide rod facilitates the fixed locking work of the locking knob.

[0011] In a preferred embodiment of the present invention, locking nuts are provided on the outside of the screw rod, located on the outside of the top and bottom of the mounting tube;

[0012] The height of the screw is adjusted by adjusting the position of the locking nut to avoid interference between the baffle and the mounting hole on the tube sheet surface and affecting the tube threading work.

[0013] In a preferred embodiment of the present invention, a slot is provided on the inner side of the plugboard seat, and one side of the blocking bar and the inner wall of the slot on the inner side of the plugboard seat are located in the same plane.

[0014] The beneficial effects of the utility model are:

[0015] The tube sheet support mechanism for installing the heat exchanger heat exchange tube can be adjusted and locked according to the required installation position of the tube sheet to ensure the distance between the tube sheets. During the installation process, the tube sheet support mechanism is prevented from displacement and the back of the tube sheet is effectively supported to avoid the tube sheet from tilting due to factors such as friction during the tube insertion process of the heat exchange tube, thereby ensuring that the tube insertion work is carried out smoothly.

[0020] The following detailed description of preferred embodiments of the present invention, combined with the accompanying drawings, will facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby more clearly defining the scope of protection of the present invention. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0021] like Figure 1-3 The tube sheet support mechanism for installing the heat exchange tubes of a heat exchanger shown in the figure includes a support base 1, a guide rod 2, a plug-in plate mechanism 3 and a blocking mechanism 4. The guide rod 2 is fixedly arranged on the inner side of the support base 1, the plug-in plate mechanism 3 is sleeved on the outside of the guide rod 2, and the blocking mechanism 4 is arranged on the back of the plug-in plate mechanism 3. The plug-in plate mechanism 3 includes a plug-in plate seat 31, a guide tube 32, a locking knob 33 and a clamping knob 34. The guide tube 32 is fixedly arranged on the outer bottom of the plug-in plate seat 31, the locking knob 33 is threadedly connected to the guide tube 32, and the clamping knob 34 is connected to one side of the plug-in plate seat 31.

[0022] Specifically, the blocking mechanism 4 includes a connecting plate 41, a mounting tube 42, a screw 43 and a baffle 44. The mounting tube 42 is fixedly arranged on the top outer side of the connecting plate 41, the screw 43 is clamped inside the mounting tube 42, and the baffle 44 is fixedly arranged on the top of the screw 43. The guide tube 32 is sleeved on the outside of the guide rod 2, and a locking groove that cooperates with the locking knob 33 is opened on the top of the guide rod 2. The outside of the screw 43 is provided with a locking nut on the outside of the top and bottom of the mounting tube 42. A slot is opened on the inside of the plug-in plate seat 31, and one side of the baffle 44 is located in the same plane as the inner wall of the slot inside the plug-in plate seat 31.

[0023] In this embodiment, first adjust the distance between the guide tube 32 and the surface of the guide rod 2 according to the required installation position of the tube plate, and then Figure 2 The right inner side of the middle insert plate seat 31 is used as the reference for measuring the distance between the tube and the plate. After adjusting the position, tighten the locking knob 33 so that its bottom is in close contact with the bottom of the locking groove on the surface of the guide rod 2, so that the guide tube 32 is fixed on the surface of the guide rod 2. Then, clamp the tube plate into the inner slot of the insert plate seat 31 and tighten it. Figure 2 The clamping knob 34 on the left side of the blade seat 31 is shown to effectively fix the scraper in the blade seat 31.

[0024] Further, adjust the position of the blocking mechanism 4, screw the locking nut on the surface of the screw 43, so that the screw 43 can be adjusted in height in the mounting tube 42, so that the blocking bar 44 on the top of the screw 43 is raised and misaligned with the mounting hole on the tube plate surface, and then tighten the locking nut to lock the height of the screw 43. Figure 2 The inner wall on the right side of the middle insert plate seat 31 is in the same plane, so the inner side of the blocking bar 44 can fit with the surface of the tube sheet to provide effective limiting support, thereby ensuring that during the tube threading process of the heat exchange tube, the tube sheet will not tilt or deform due to factors such as friction, thereby facilitating the tube threading work.
