Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a shell and tube condenser. Background Art

[0002] Power plants use many condensers to condense the steam discharged from turbines. Condensers are used in refrigeration plants to condense refrigerant vapors such as ammonia and Freon. Condensers are used in the petrochemical industry to condense hydrocarbons and other chemical vapors. In the distillation process, the device that converts vapor into liquid is also called a condenser. All condensers operate by removing heat from gases or vapors.

[0003] During the operation of the condenser, vibration will be generated when the inlet and outlet water are exchanged due to the unstable flow pressure of the cooling medium. During the vibration, the base and the shell of the condenser collide with each other. The existing technology has poor shock absorption effect, which easily causes damage to the condenser equipment and reduces the service life of the condenser. Therefore, we propose a shell and tube condenser to solve the above problems. Utility Model Content

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figures 1-4 As shown, a shell and tube condenser includes a fixed plate 1, a connecting member 4 and an anti-slip pad 15. A slider 12 is slidably connected to the front and rear positions of the inner surface of the fixed plate 1. A first rotating seat 11 is fixedly installed at the top center of the slider 12. Guide rods 10 are fixedly connected to the front and rear inner surfaces of the fixed plate 1 on both sides. The outer surface of the guide rod 10 is sleeved with a first buffer spring 13. Second rotating seats 8 are fixedly installed at the front and rear positions on both sides of the bottom of the connecting member 4. A connecting rod 9 is fixedly connected to the opposite side of the first rotating seat 11 and the second rotating seat 8. Damper 2 is fixedly installed on both sides of the front and rear outer surfaces of the fixed plate 1. The outer surface of the damper 2 is sleeved with a second buffer spring 3. Columns 14 are fixedly connected to the front and rear positions on both sides of the top of the anti-slip pad 15.

[0023] The effect achieved by the entire embodiment 1 is as follows: Figure 1 and Figure 3 As shown, when vibration is generated during the operation of the condenser body 5, the vibration can be buffered by the mutual cooperation of the first rotating seat 11, the second rotating seat 8, the slider 12, the guide rod 10 and the first buffer spring 13, and the second buffer spring 3 and the damper 2 can play an auxiliary buffering role, thereby protecting the entire condenser body 5 and extending its service life.

[0024] Example 2, as Figures 1-4As shown, both sides of the first buffer spring 13 are fixedly connected to the front and rear outer surfaces of the slider 12, one end of the second buffer spring 3 is fixedly connected to the outer surface of the fixed plate 1, and the other end of the second buffer spring 3 is fixedly connected to the bottom surface of the connecting member 4. The inner surface of the connecting member 4 is slidingly connected to the condenser body 5. The front and rear outer surfaces of the connecting member 4 are threaded with bolts 6 near the top position. Threaded holes 7 are provided on the front and rear outer surfaces of the connecting member 4 at the position of the bolt 6. The inner wall of the threaded hole 7 is threadedly connected to the outer surface of the bolt 6. The outer surface of the bolt 6 threads through the outer surface of the condenser body 5. An electric push rod 17 is fixedly installed at the inner bottom center of the column 14. The protruding end of the electric push rod 17 is fixedly connected to the connecting rod 16. The top end face of the connecting rod 16 is fixedly connected to the bottom surface of the fixed plate 1, and the outer surface of the connecting rod 16 is slidingly connected to the inner surface of the column 14.

[0025] The effect achieved by the entire embodiment 2 is as follows: Figure 1 As shown, the condenser body 5 is fixed to the inside of the connecting member 4 by means of bolts 6. The arrangement of the bolts 6 and the threaded holes 7 makes it convenient for users to disassemble and assemble it, and the disassembly and assembly process is relatively simple, so that it does not take too much time each time of disassembly and assembly. The height of the condenser body 5 is adjustable by means of the electric push rod 17 and the connecting rod 16, so that it can be adjusted according to different usage requirements later. The arrangement of the anti-slip pad 15 prevents the overall displacement during use.

[0026] Working principle: After the user puts the condenser body 5 into the interior of the connector 4, multiple bolts 6 can be screwed into the corresponding threaded holes 7. Screwing in the bolts can limit the condenser body 5 so that it can be stably placed on the connector 4. If the height of the condenser body 5 needs to be adjusted, the electric push rod 17 is started to extend or retract, driving the connecting rod 16 to move up and down in the column 14. The connecting rod 16 can move the fixing plate 1, the connector 4 and the condenser body 5, so that the height of the condenser body 5 can be adjusted so that it can be better used later. When the condenser body 5 vibrates during operation, the second rotating seat 8 first feels the force and moves downward. At this time, the connecting rod 9 will change its inclination angle, driving the first rotating seat 11 and the slider 12 to move toward the center. When moving, the first buffer spring 13 can be squeezed. Through the cooperation of the first buffer spring 13, the force can be reduced, and when the connecting part 4 moves downward under the force, the damper 2 and the second buffer spring 3 are forced to change their own state. Through the cooperation of the two, they can play a role of auxiliary buffering and absorption, thereby protecting the condenser body 5.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
