Description

Technical Field

[0001] This utility model relates to the field of solvent condensation technology, and in particular to a condensation device for solvent purification equipment. Background Technology

[0002] In solvent purification processes in chemical, pharmaceutical, and food processing industries, shell-and-tube condensers are the core equipment for condensing and liquefying gaseous solvents. Cleaning solutions for shell-and-tube condensers often focus on the inside of the condenser tubes, using methods such as high-pressure water flushing and mechanical scraping to remove residual solvent residues or scale inside the tubes to ensure the flow efficiency of the medium inside the tubes. However, during use, impurities in the cooling medium gradually deposit on the outer wall of the condenser tubes, forming a scale layer. This scale layer significantly increases the thermal resistance of the condenser tubes, reduces the heat exchange efficiency of the tube wall, and leads to insufficient condensation of gaseous solvents. This not only causes a decrease in solvent recovery rate and an increase in purification energy consumption, but also affects production. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a condensation device for solvent purification equipment. The condensation device for solvent purification equipment includes a main component 1, including a shell 11. A tube sheet 12 is fixed inside the shell 11. The tube sheet 12 is fixed to the shell 11 by welding. A plurality of condensation tubes 13 are welded on the tube sheet 12.

[0029] The cleaning component 2, located on the outside of the condenser tube 13, includes a cleaning element 21. The cleaning element 21 is used to clean the scale on the outer wall of the condenser tube 13, thereby improving the heat exchange efficiency.

[0030] The cleaning component 21 includes a movable ring 211 that is slidably disposed within the housing 11. The size of the outer wall of the movable ring 211 corresponds to the inner wall of the housing 11. A through groove corresponding to the condenser tube 13 is opened on the movable ring 211. The condenser tube 13 is inserted into the through groove. A brush head is provided on the inner wall of the through groove. When the movable ring 211 slides relative to the condenser tube 13, the brush head on the inner wall of the through groove can clean the outer wall of the condenser tube 13 and scrape off the scale attached to its outer wall.

[0031] The bottom of the movable ring 211 is provided with a rotating plate 212. The bottom of the movable ring 211 has a notch and is not a complete circle. When the rotating plate 212 rotates to be on the same plane as the movable ring 211, the rotating plate 212 can fill the gap between the movable ring 211 and the inner wall of the outer shell 11.

[0032] A fixed shaft 213 is fixed inside the rotating plate 212. Support blocks 214 are connected to the bearings on both sides of the fixed shaft 213. The support blocks 214 are fixed on the moving ring 211 and are used to provide stable support for the fixed shaft 213.

[0033] Damping is provided in the bearing connection between the fixed shaft 213 and the support block 214. Part of the rotating plate 212 is in contact with the support block 214, and a high-temperature resistant friction block is provided between the two. Only when subjected to a large external force will the fixed shaft 213 and the support block 214 rotate relative to each other, that is, the rotating plate 212 rotates relative to the moving ring 211.

[0034] There are multiple moving rings 211. At the initial position, with... Figure 2 Based on the perspective, the leftmost moving ring 211 is separated from the left tube plate 12 by one unit length, and the remaining moving rings 211 are also separated by the same unit length, while the gap between the rightmost moving ring 211 and the right tube plate 12 is smaller.

[0035] Example 2 Reference Figures 4-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, a trigger plate 215 is fixed on the fixed shaft 213, a fixed block 216 is fixed on the inner wall of the outer casing 11, and a push block 217 is fixed on the fixed block 216. As the moving ring 211 moves, the trigger plate 215 can contact the push block 217, and the push block 217 will push the trigger plate 215 to rotate, thereby applying additional pressure to the rotating plate 212, causing it to rotate relative to the moving ring 211.

[0037] Specifically, there are multiple fixed blocks 216 and push blocks 217. The push blocks 217 are divided into two groups: right push block 217-1 and left push block 217-2. Figure 6 Based on the perspective, the right push block 217-1 is located to the right of the fixed block 216, while the left push block 217-2 is located to the left of the fixed block 216.

[0038] A right push block 217-1 is provided on one side of the left tube plate 12, while a left push block 217-2 is provided on one side of the right tube plate 12.

[0039] Specifically, the outer casing 11 has an inlet 11-1 and an outlet 11-2.

[0040] During cleaning, water can be added to the outer casing 11 through the inlet 11-1, and the water flow can carry the dirt out through the outlet 11-2.

[0041] When the moving ring 211 moves toward the outlet 11-2, the moving ring 211 is coaxial with the rotating plate 212. The rotating plate 212 can push the dirt toward the outlet 11-2. As the moving ring 211 moves, the right push block 217-1 will contact the trigger plate 215 and squeeze the trigger plate 215, causing the trigger plate 215 to rotate, which in turn drives the rotating plate 212 to rotate. It will not stick to the inner wall of the outer shell 11. Then the moving ring 211 moves away from the outlet 11-2. At this time, the rotating plate 212 will maintain an inclined state and will not push the dirt that has sunk to the bottom of the outer shell 11 away from the outlet 11-2. When the moving ring 211 is about to move to the initial position, the inclined trigger plate 215 will contact the left push block 217-2 and be squeezed by the left push block 217-2, causing the trigger plate 215 to rotate in the opposite direction, thereby resetting the rotating plate 212 and making it coplanar with the moving ring 211 again.

[0042] When the rotating plate 212 and the moving ring 211 push the dirt towards the outlet 11-2, the dirt will be located on the left side of the rotating plate 212. Under the action of the water flow, the dirt will also be driven to move towards the outlet 11-2. When the moving ring 211 moves a unit distance towards the outlet 11-2 and then resets, the positions of the two moving rings 211 coincide. When the moving ring 211 on the left moves, it can also carry the dirt that has been cleaned up by the moving ring 211 on its right. With the action of the water flow, the dirt is discharged from the outlet 11-2.

[0043] Specifically, a baffle 218 is fixed on the moving ring 211, and the rotating plate 212 can fit against the baffle 218.

[0044] The baffle 218 is provided to restrict the rotation of the rotating plate 212, so that the rotating plate 212 can only rotate in one direction.

[0045] Example 3 Reference Figure 7 and Figure 8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0046] Specifically, the cleaning component 2 also includes a pull member 22 located on the housing 11. The pull member 22 is configured to move the moving ring 211 to complete the cleaning operation.

[0047] There are multiple moving rings 211, and adjacent moving rings 211 are connected and fixed by a connecting rod 227. Each moving ring 211 can move synchronously.

[0048] The pulling component 22 includes a pull rope 221 fixed on the moving ring 211. A winding wheel 222 is provided on one side of the outer casing 11. The other end of the pull rope 221 is fixed on the winding wheel 222. A rotating shaft 223 is fixed inside the winding wheel 222. A handle 228 is fixed on one side of the rotating shaft 223. Rotating the handle 228 drives the rotating shaft 223 and the winding wheel 222 to rotate.

[0049] Auxiliary blocks 224 are connected to the bearings on both sides of the rotating shaft 223. The auxiliary blocks 224 are fixed on the outer shell 11 and provide support for the rotating shaft 223.

[0050] The pull cord 221 passes through the outer casing 11, with part of it located inside the outer casing 11 and part of it located outside the outer casing 11. The outer casing 11 has a through hole corresponding to the pull cord 221. A dynamic sealing component is provided at the through hole, which allows the pull cord 221 to move relative to the through hole and can fill the gap between the pull cord 221 and the inner wall of the through hole to block leakage and ensure the sealing of the outer casing 11. This is prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0051] Specifically, a locking block 225 is slidably disposed inside the auxiliary block 224. A spring 226 is fixed to one end of the locking block 225, and the other end of the spring 226 is fixed to the auxiliary block 224. A slot 222-1 is provided on the winding wheel 222. The spring 226 applies a continuous pushing force to the locking block 225 to ensure that the locking block 225 can engage with the slot 222-1. The spring 226 has a large elastic force. When the locking block 225 engages with the slot 222-1, the rotation of the winding wheel 222 will be restricted, thereby limiting the length of the pull rope 221.

[0052] Specifically, one side of the 225 card is arc-shaped.

[0053] The arc-shaped design allows the slot 222-1 to press against the arc end face of the block 225 when the take-up roller 222 rotates, thus compressing the spring 226. After that, the block 225 will not obstruct the rotation of the take-up roller 222.

[0054] Because the spring 226 has a large elastic force, a large force is required to overcome the elastic force of the spring 226 when the take-up wheel 222 is rotated. Only then can the take-up wheel 222 be rotated. Correspondingly, without other large external forces, the take-up wheel 222 cannot be rotated, thus locking the length of the pull rope 221 that the take-up wheel 222 unwinds.

[0055] Specifically, there are multiple slots 222-1, which are evenly distributed in a circle on the take-up reel 222. By setting multiple slots 222-1, after the take-up reel 222 stops rotating, the slots 222-1 can engage with the block 225, thereby restricting the rotation of the take-up reel 222.

[0056] Specifically, there are two sets of pull ropes 221 and take-up reels 222. One set of pull ropes 221 is fixed to the leftmost moving ring 211. Rotating the take-up reels 222 of this set will drive all the moving rings 211 to move towards the outlet 11-2. The other set of pull ropes 221 is located on the rightmost moving ring 211. Rotating the take-up reels 222 of this set will drive all the moving rings 211 to move away from the outlet 11-2.

[0057] When the rotation of both sets of winding wheels 222 is locked, the position of the moving ring 211 will be fixed relative to the outer casing 11. The moving ring 211 can also provide auxiliary support for the condenser tube 13.

[0058] During use, water is poured into the housing 11 from the inlet 11-1, and the outlet 11-2 is closed. Then, cleaning begins. The handle 228 near the outlet 11-2 is turned to rotate the shaft 223 and the winding wheel 222. The pull rope 221 pulls all the moving rings 211 toward the outlet 11-2. The grooves of the moving rings 211 and the brush head will clean the outer wall of the condenser tube 13 and scrape off the scale. At this time, the moving rings 211 and the rotating plate 212 are coaxial. The rotating plate 212 can push the dirt toward the outlet 11-2. As the moving rings 211 move, the right push block 217-1 will contact the trigger plate 215 and squeeze the trigger plate 215, causing the trigger plate 215 to rotate, which in turn drives the rotating plate 212 to rotate. It will not stick to the inner wall of the housing 11.

[0059] Then, rotating the handle 228 away from the outlet 11-2 drives the rotating shaft 223 and the winding wheel 222 to rotate. The pull rope 221 pulls all the moving rings 211 to move away from the outlet 11-2. At this time, the rotating plate 212 will remain tilted and will not push the dirt that has sunk to the bottom of the housing 11 away from the outlet 11-2. When the moving rings 211 are about to move to the initial position, the tilted trigger plate 215 will contact the left push block 217-2 and be squeezed by the left push block 217-2, causing the trigger plate 215 to rotate in the opposite direction, thereby resetting the rotating plate 212 and making it coplanar with the moving rings 211 again.

[0060] Repeat the above operation, while opening outlet 11-2 and continuously releasing water through inlet 11-1. Under the action of water flow, the dirt is carried out from outlet 11-2. Repeated operation causes the moving ring 211 to slide relative to the condenser tube 13, thereby hanging the dirt off the outer wall of the condenser tube 13, thus improving the heat transfer efficiency.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
