Description

Technical Field

[0001] The utility model belongs to the technical field of condensers, and particularly relates to a drainage structure for a condenser. Background Art

[0002] A condenser is a key component in a refrigeration system and belongs to a type of heat exchanger. Among them, a shell-and-tube condenser is a condenser that uses a shell and tubes as a heat transfer medium and is widely used in refrigeration devices. The shell-and-tube condenser mainly consists of components such as a shell, an inner cylinder, an outer cylinder, a partition plate, and fastening bolts. A tube bundle is arranged inside it, and the medium to be condensed (such as refrigerant gas) flows inside the tube bundle, while the outside of the tube bundle is cooled by a cooling medium (such as water, air, etc.). When the high-temperature and high-pressure refrigerant gas enters the tube bundle, it exchanges heat with the cooling medium outside the tube bundle, transfers the heat to the cooling medium, thereby cooling the refrigerant gas and condensing it into a liquid. In a shell-and-tube condenser, hot gas or vapor enters the condenser tube through a pipeline. Outside the condenser tube, the cooling medium (such as water or air) absorbs heat through natural convection or forced convection. During this process, the hot gas or vapor cools and condenses into a liquid, and these liquids are the condensed water. The drain outlet of the shell-and-tube condenser is usually designed at the bottom or side of the condenser to effectively collect and discharge the condensed water.

[0003] The problem existing in the prior art is that after the shell-and-tube condenser performs heat exchange work, if the condensed water in it is not discharged in time, the condensed water stays in the condenser for a long time, forming a water film covering the surface of the condenser tube, which will hinder the effective transfer of heat and reduce the heat exchange efficiency of the condenser. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides a drainage structure for a condenser, which has the advantages of fixedly docking the discharge pipeline at the bottom of the discharge pipe of the condenser to ensure that the condensed water can be discharged quickly and smoothly after being generated, and solves the problem that after the existing shell-and-tube condenser performs heat exchange work, if the condensed water in it is not discharged in time, the condensed water stays in the condenser for a long time, forming a water film covering the surface of the condenser tube, which will hinder the effective transfer of heat and reduce the heat exchange efficiency of the condenser.

[0020] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 to 4 shown, a drainage structure for a condenser provided by an embodiment of the present utility model includes a main body 1, a fixing structure 2, a positioning structure 3, a fixing block 4 and a fixing component 5.

A positioning structure 3 is fixedly connected to the front surface of the main fixing ring 201. The positioning structure 3 includes a fixing block 4 and a fixing component 5. The fixing component 5 is arranged inside the fixing block 4.

[0022] Refer to Figure 3 and Figure 4, the fixed block 4 is arranged on the front surface of the main fixed ring 201, the back surface of the fixed block 4 is fixedly connected to the front surface of the main fixed ring 201, a slotted groove 8 is formed on the right side of the fixed block 4, the fixed block 4 is sleeved on the inner wall of the connecting block 7 through the slotted groove 8, and fixing rods 9 are fixedly connected to the upper and lower sides of the inner wall of the fixed block 4.

[0023] With the above scheme: by arranging the fixed block 4, the connecting block 7 can extend into the interior of the fixed block 4 through the slotted groove 8, so that the connecting block 7 can be fixed and limited by the fixing assembly 5, thereby fixedly connecting the main fixed ring 201 and the auxiliary fixed ring 202, and fixedly connecting the water outlet pipe 6 to the bottom of the discharge pipe 103 to carry out the drainage work.

[0024] Reference Figure 3 and Figure 4 , the fixing assembly 5 includes a linkage block 10, the linkage block 10 is arranged on the left side of the fixed block 4, the right end of the linkage block 10 extends and penetrates into the inner wall of the fixed block 4, a pressing block 11 is fixedly connected to the left side of the linkage block 10, and two linkage arms 12 are arranged on the right side of the linkage block 10.

[0025] With the above scheme: by arranging the linkage block 10, when the pressing block 11 is pressed, it can drive the linkage block 10 to move to the right, and thus the linkage block 10 can drive the two linkage arms 12 to move simultaneously during the movement process.

[0026] Reference Figure 4 , the two linkage arms 12 are both arranged on the inner wall of the fixed block 4, the two linkage arms 12 are arranged in a staggered manner respectively, the left ends of the two linkage arms 12 are respectively fixedly connected to the right side of the linkage block 10, linkage grooves 13 are respectively formed on the surfaces of the two linkage arms 12, and linkage rods 14 are respectively sleeved on the inner walls of the two linkage grooves 13.

[0027] With the above scheme: by arranging the linkage arms 12, the two linkage arms 12 can squeeze the surfaces of the two linkage rods 14 through the linkage grooves 13 during the movement process, so as to drive the two linkage rods 14 to move respectively.

[0029] With the above scheme: by arranging the linkage rods 14, when the two linkage arms 12 move, they squeeze the surfaces of the two linkage rods 14 through the linkage grooves 13, causing the two linkage rods 14 to move in a staggered manner, and thereby driving the two moving arms 15 to move respectively.

[0030] Reference Figure 4, the middle parts of the two moving arms 15 are respectively slidably connected to the outer surface of the fixed rod 9. On one side where the two moving arms 15 are close to each other, a fixed spring 16 is fixedly connected. The fixed spring 16 is sleeved on the surface of the fixed rod 9. Positioning blocks 17 are respectively arranged at the right ends of the two moving arms 15.

[0031] With the above solution: By setting the moving arms 15, the two linkage rods 14 can respectively drive the two moving arms 15 to slide close on the surface of the fixed rod 9, and compress the fixed spring 16. The two moving arms 15 slide close and respectively drive the movement of the two positioning blocks 17 closer.

[0032] Reference Figure 4 , the two positioning blocks 17 are respectively fixedly connected to the sides of the right ends of the two moving arms 15 that are far from each other. The ends of the two positioning blocks 17 that are far from each other are respectively inserted into the inner wall of the connection groove 701.

[0033] With the above solution: By setting the positioning blocks 17, when the two positioning blocks 17 move closer, they can respectively disengage from the connection groove 701 to release the fixed limit on the connection block 7, thereby releasing the fixed connection between the secondary fixing ring 202 and the main fixing ring 201.

[0034] During use, connect the water outlet pipe 6 to the bottom of the discharge pipe 103. Then, sleeved the main fixing ring 201 and the secondary fixing ring 202 on the connection part of the water outlet pipe 6 and the discharge pipe 103, and make the two rubber sleeves 203 wrap and tightly adhere to the connection part. Then, press the front sides of the main fixing ring 201 and the secondary fixing ring 202 tightly, so that the secondary fixing ring 202 can drive the connection block 7 to be inserted into the inner wall of the fixing block 4 through the slot 8. The connection block 7 moves leftward and squeezes the two positioning blocks 17 to move away. As the connection block 7 moves away, the fixed spring 16 pulls the two moving arms 15 to slide close on the surface of the fixed rod 9, thereby driving the two positioning blocks 17 to be respectively inserted into the inner wall of the connection groove 701 to fix and limit the connection block 7, and making the main fixing ring 201 and the secondary fixing ring 202 fixedly connected. Subsequently, the water flow inside the main body 1 flows into the water outlet pipe 6 through the discharge pipe 103 and is discharged to carry out the drainage work. After completion, press the pressing block 11 to drive the movement of the linkage block 10, and thereby drive the movement of the two linkage arms 12. The two linkage arms 12 move and respectively squeeze the two linkage rods 14 to move closer through the linkage grooves 13, so that the two linkage rods 14 respectively drive the two moving arms 15 to slide close on the surface of the fixed rod 9, and compress the fixed spring 16. The two moving arms 15 slide close and then drive the movement of the positioning blocks 17 closer, so that the two positioning blocks 17 disengage from the connection groove 701 to release the fixed limit on the connection block 7. Subsequently, the secondary fixing ring 202 can be rotated to the right, driving the connection block 7 to disengage from the slot 8, releasing the fixed connection between the main fixing ring 201 and the secondary fixing ring 202, and the water outlet pipe 6 can be removed.
