Description

Technical Field

[0001] The utility model relates to the technical field of chemical products, in particular to a heat exchange equipment for propane deasphalting. Background Art

[0002] Propane deasphalting is a commonly used deasphalting method, which can remove asphalt by converting asphalt from solid to liquid or gas by heating. In this process, commonly used heat exchange equipment includes heating furnaces, heat exchangers and coolers. Heat exchange equipment is also commonly called heat exchanger or heat converter. It is a device for heat transfer, which can achieve heat transfer or conversion between different fluids. The basic principle of the heat exchange device is to achieve heat transfer by making two fluids (such as heat source fluid and heated fluid) contact on the exchange surface. The heat exchange device is usually composed of a shell and an internal heat transfer surface (such as pipes, plates, etc.). Among them, one fluid transfers its heat to another fluid through the heat transfer surface.

[0003] A heat exchanger is also called a heat exchanger. Currently, heat exchangers are generally fixed and installed by bolts. Although the installation is relatively firm, it is not convenient for subsequent disassembly, inspection and maintenance. At the same time, after installation, the vibration generated when the exchanger body is working can easily loosen the parts in the shell and tube heat exchanger, thereby accelerating the wear of the equipment, reducing the life of the equipment and increasing the cost of maintenance and repair. Utility Model Content

[0004] The utility model aims to provide a propane deasphalting heat exchange equipment to solve the problems raised in the above background technology.

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

[0013] When the heat exchange device body generates vibration during operation, the pressure is pressed down by the positioning column to squeeze one of the sliding rings. At this time, the sliding ring drives the movable plate to buffer the squeezing of the spring, thereby offsetting a certain vibration pressure. The twisting block is rotated to rotate the threaded rod in the inner cavity of the threaded sleeve to move the clamping ring. When the clamping ring moves, it contacts and positions with the heat exchange device body, thereby facilitating installation. When the user needs to disassemble the heat exchange device body, the twisting block is twisted to drive the threaded rod to separate the clamping ring from the surface of the heat exchange device body, so that the device can be quickly disassembled.

DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] See also Figure 1-4 As shown, a heat exchange equipment for propane deasphalting includes a positioning plate 1, and also includes: a heat exchange device body 2 arranged on the top of the positioning plate 1, positioning columns 3 are fixedly connected to both sides of the top of the positioning plate 1, and a support column 4 is arranged on the top of the inner cavity of the positioning column 3; a positioning ring 5 is arranged on the top of the support column 4, and the front and rear sides of the positioning ring 5 are fixedly connected to connecting plates 6; and a buffer mechanism 7 is arranged in the inner cavity of the positioning column 3.

[0021] refer to Figure 2 and Figure 3 As shown, the front and rear sides of both sides of the positioning plate 1 are fixedly connected with mounting plates 8, the top of the mounting plate 8 is provided with mounting holes 9, both sides of the positioning column 3 are fixedly connected with reinforcement blocks 10, the bottom of the reinforcement block 10 is fixedly connected to the positioning plate 1, the opposite sides of the two connecting plates 6 are provided with threaded sleeves 11, the inner cavity of the threaded sleeves 11 is provided with threaded rods 12, the opposite sides of the two threaded rods 12 are fixedly connected with torsion blocks 13, the opposite sides of the two threaded rods 12 are fixedly connected with clamping rings 14, the side of the clamping ring 14 close to the connecting plate 6 is fixedly connected with a limiting rod 15, the opposite sides of the two limiting rods 15 penetrate to the outside of the connecting plate 6 and are fixedly connected with a limiting ring 16.

[0022] It should be noted that: through the arrangement of the mounting plate 8 and the mounting hole 9, it is convenient to install and fix the positioning plate 1. The fixed connection between the reinforcement block 10 and the positioning plate 1 plays the role of reinforcing the positioning column 3. By placing the heat exchange device body 2 on the top of the positioning ring 5, the twisting block 13 is rotated to rotate the threaded rod 12 in the inner cavity of the threaded sleeve 11 to move the clamping ring 14. When the clamping ring 14 moves, it contacts and positions with the heat exchange device body 2, thereby facilitating installation. When the user needs to disassemble the heat exchange device body 2, the twisting block 13 is twisted to drive the threaded rod 12 to rotate in the inner cavity of the threaded sleeve 11 to move the clamping ring 14. When the clamping ring 14 moves, it drives the limit rod 15 to move in a limited manner to detach from the heat exchange device body 2 for quick disassembly. The limit rod 15 can be limited by the limit ring 16 to prevent slipping.

[0023] refer to Figure 1 Figure 2 and Figure 4As shown, the buffer mechanism 7 includes a positioning rod 701, the bottom of which is fixedly connected to the inner wall of the positioning column 3, the top and bottom of the surface of the positioning rod 701 are sleeved with sliding rings 702, the opposite sides of the two sliding rings 702 are fixedly connected with movable plates 703 through hinges, the sides of the two movable plates 703 away from the sliding rings 702 are connected through hinges, the opposite sides of the two sliding rings 702 are fixedly connected with springs 704, the front and rear sides of the positioning column 3 are provided with openings for use with the movable plates 703, and the damper body 705 is fixedly connected between the two movable plates 703 through hinges.

[0024] It should be noted that: when the heat exchange device body 2 generates vibration during operation, the pressure is pressed down through the positioning column 3 to squeeze one of the sliding rings 702. At this time, the sliding ring 702 is forced to drive the movable plate 703 to descend, and the spring 704 is squeezed when the movable plate 703 descends, thereby achieving a certain buffering effect on the pressure. At the same time, when the movable plate 703 is squeezed, the damper body 705 will be squeezed, thereby assisting shock absorption and reducing the negative impact of vibration on the heat exchange device body 2.

[0025] Working principle: First, install the positioning plate 1 through the installation hole 9, then place the heat exchange device body 2 on the top of the positioning ring 5, and rotate the twisting block 13 to rotate the threaded rod 12 in the inner cavity of the threaded sleeve 11 to move the clamping ring 14. When the clamping ring 14 moves, it contacts and positions with the heat exchange device body 2, so as to facilitate installation. When the heat exchange device body 2 vibrates during operation, the pressure is pressed down by the positioning column 3 to squeeze one of the sliding rings 702. At this time, the sliding ring 702 is forced to drive the movable plate 703 to descend. When 703 descends, it squeezes the spring 704, thereby achieving a certain buffering effect on the pressure. At the same time, when the movable plate 703 is squeezed, the damper body 705 will be squeezed, thereby assisting in shock absorption and reducing the negative impact of vibration on the heat exchange device body 2. When the user needs to disassemble the heat exchange device body 2, the twisting block 13 drives the threaded rod 12 to rotate in the inner cavity of the threaded sleeve 11 to move the clamping ring 14. When the clamping ring 14 moves, it drives the limit rod 15 to move and separate from the heat exchange device body 2 for quick disassembly.
