Description

Technical Field

[0001] This utility model relates to the field of chemical process machinery and equipment technology, and in particular to an energy-saving double-effect extraction and concentrator. Background Technology

[0002] The energy-saving double-effect extractor concentrator is a highly efficient liquid concentration device, widely used in industries such as traditional Chinese medicine, Western medicine, food, and chemicals. It mainly consists of a first-effect tube heater, an evaporation chamber, a second-effect tube heater, a concentration pot, a condenser, a vacuum solvent recovery tank, a plate heat exchanger, and a vacuum buffer tank.

[0003] The energy-saving double-effect extractor and concentrator combines external heating and natural circulation with vacuum negative pressure evaporation. Its working principle is as follows: boiler steam enters the shell side of the first-effect heating chamber, heating the liquid material inside the tubes. As the liquid level rises, it is sprayed into the evaporation chamber through nozzles for vapor-liquid separation. Due to the density difference between the separated liquid and the unboiled liquid in the circulation tube, as well as the expansion kinetic energy generated by heating, the separated liquid returns to the lower part of the heating chamber for reheating, thus forming a natural circulation. The energy-saving double-effect extractor and concentrator is widely used in various fields. In the pharmaceutical industry, it plays a vital role in both the concentration of traditional Chinese medicine extracts and the processing of Western medicine solutions. Through low-temperature vacuum concentration, it effectively protects the heat-sensitive components in drugs, improves drug quality, and reduces vibrations. These vibrations are directly transmitted to various parts of the equipment, which over time can lead to loosening of connections, damage to seals, accelerated wear, reduced equipment lifespan, increased maintenance costs and downtime. Bolts at pipe connections may gradually loosen due to vibration, causing material leakage. The fixing devices of heating elements may be damaged by vibration, affecting the heating effect. Therefore, an energy-saving double-effect extraction and concentration device is proposed to solve the above problems. Utility Model Content

[0007] As a further description of the above technical solution:

[0008] The sealing assembly includes a first transmission pipe, the right end of which is fixedly connected to the top outer wall of the first heating tank.

[0011] As a further description of the above technical solution:

[0012] Spring 3 is fixedly connected to the far side of each of the two L-shaped plates, and two inclined blocks are fixedly connected to the outer wall of each of the connecting plates 2;

[0013] As a further description of the above technical solution:

[0014] The bottom ends of the plurality of sliders are slidably connected to the top of the support plate, and the outer wall of the fixing block is slidably connected to the top of the transmission tube.

[0015] As a further description of the above technical solution:

[0016] The top ends of the multiple connecting plates are rotatably connected to the bottom end of the fixed plate, and the left and right ends of the multiple springs are fixedly connected to the outer walls of the multiple sliders.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when vibration occurs, the slider slides along the guide rod and compresses the first spring, causing the first connecting plate to move. The second spring connects the support frame and the first fixed plate, providing buffer support for the first heating tank. The vibration damping component can prevent structural fatigue damage caused by long-term severe vibration, such as bracket deformation and cracking of shell welds, which could lead to potential safety hazards. Especially under high pressure and high temperature concentration conditions, a stable equipment structure can effectively reduce the risk of material leakage and ensure production safety. In addition, the vibration damping design can also reduce the occurrence of parts falling off or foreign objects entering the equipment due to vibration, avoid production accidents caused by mechanical failure, and improve the reliability of equipment operation.

[0023] 2. In this utility model, by rotating the connecting plate two on the outer wall of the fixed plate two, the connecting rod one is driven to operate. The connecting rod one drives the fixed block to slide on the top of the transmission pipe one, engaging with the connecting rod two fixed to the transmission pipe two. The inclined blocks fixed on both sides of the connecting plate two contact the L-shaped plate rotating on the mounting plate. The L-shaped plate is reset by the spring three, fixing the connecting plate two and achieving a sealing effect. During the concentration process, the material usually has certain value, especially in the pharmaceutical and chemical industries. The sealing structure ensures the circulation and concentration of the material within the equipment, preventing material waste due to leakage, reducing production costs, and preventing external dust and impurities from entering the material, ensuring the purity and quality of the concentrated product. This is crucial for industries with high hygiene requirements, such as pharmaceuticals and food, and helps meet relevant quality standards and regulations. Attached Figure Description

A sealing component for sealing is installed at the top of the heating tank 9. The top of the heating tank 9 provides the installation position for the sealing component. The sealing component achieves the sealing of the heating tank 9.

[0033] Reference Figures 2 to 4 The sealing assembly includes a transmission pipe 10, which serves as a conveying channel for transporting materials or steam. The right end of the transmission pipe 10 is fixedly connected to the top outer wall of the heating tank 9. The top outer wall of the heating tank 9 provides an installation position for the transmission pipe 10. The fixed connection allows the transmission pipe 10 to communicate with the interior of the heating tank 9, serving as an output channel for materials or steam. An installation plate 11 is fixedly connected to the outer wall of the transmission pipe 10, providing an installation base for the installation plate 11. The fixed connection makes the installation plate 11 perpendicular to the transmission pipe 10, providing a support platform for other components of the sealing assembly. Two fixing plates 12 are fixedly connected to the top of each installation plate 11. The top of the installation plate 11 provides installation points for the two fixing plates 12, preventing internal component transport from shaking. A connecting plate 13 is rotatably connected to the adjacent side of each of the two fixing plates 12. The adjacent side of the fixing plates 12 provides a rotation fulcrum for the connecting plate 13. The connecting plate 13 can rotate between the fixing plates 12 through a shaft hole fit.

The top left side of the mounting plate 11 is rotatably connected to two L-shaped plates 18. The top left side of the mounting plate 11 provides a rotation fulcrum for the two L-shaped plates 18. The L-shaped plates 18 can rotate on the mounting plate 11 through the shaft hole cooperation.

[0035] Reference Figures 2 to 4 The tops of the two support frames 1 are fixedly connected to the heating tank 21, providing installation support for the heating tank 21 and forming a double-effect extraction and concentration structure to improve energy utilization. The outer wall of the heating tank 9 is fixedly connected to the transmission pipe 22, providing an installation position for the transmission pipe 22.

Two inclined blocks 20 are fixedly connected to the outer wall of the connecting plate 2 13. The outer wall of the connecting plate 2 13 provides a mounting base for the inclined blocks 20. The fixed connection allows the inclined blocks 20 and the connecting plate 2 13 to move synchronously. The bottom ends of multiple sliders 4 are slidably connected to the top of the support plate 2. The top of the support plate 2 provides sliding support for the sliders 4. The plane contact allows the sliders 4 to slide along the top of the support plate 2, limiting the movement trajectory of the sliders 4.

[0036] The outer wall of the fixed block 15 is slidably connected to the top of the transmission tube 10. The top of the transmission tube 10 provides a sliding track for the fixed block 15. The fixed block 15 can slide along the top of the transmission tube 10 through the design of the groove or guide rail, ensuring its stability during movement. The top ends of multiple connecting plates 6 are rotatably connected to the bottom end of the fixed plate 8. The bottom end of the fixed plate 8 provides a rotation fulcrum for the connecting plate 6. The connecting plate 6 can rotate freely at the bottom end of the fixed plate 8 through the shaft hole fit. The left and right ends of multiple springs 5 ​​are fixedly connected to the outer walls of multiple sliders 4. The two ends of the springs 5 ​​are respectively connected to the adjacent sliders 4, providing buffer and restoring force when the sliders 4 move, enhancing the stability of the structure. The outer walls of the two L-shaped plates 18 are in contact with the tops of the two inclined blocks 20. The L-shaped plates 18 achieve the effect of fixing the connecting plate 13 through contact with the inclined blocks 20.

[0037] The outer wall of the fixing block 15 has a slot for engaging with the connecting rod 17. The slot structure can lock or release the connecting rod 17, thereby locking and unlocking the transmission tube 16. The other ends of the two springs 19 are fixedly connected to the outer wall of the mounting plate 11. The outer wall of the mounting plate 11 provides a fixed end for the springs 19. The elasticity of the springs 19 ensures that the L-shaped plate 18 maintains its initial position when not in operation, facilitating the next operation. The outer wall of the fixing block 15 contacts the outer wall of the connecting rod 17. The outer wall of the fixing block 15 and the outer wall of the connecting rod 17 are in planar contact. When the fixing block 15 moves, it pushes the connecting rod 17, thereby causing the transmission tube 16 to slide.

[0038] Working principle: When the heating tank 9 vibrates, the vibration is transmitted to the fixed plate 8 connected to the inner wall. Under the buffering action of the spring 7, the fixed plate 8 drives the multiple connecting plates 6 connected to it to swing, which in turn causes the slider 4 connected to the bottom of the connecting plate 6 to slide on the outer wall of the guide rod 3, squeezing the spring 5 sleeved on the guide rod 3, thus buffering the heating tank 9. The support frame 1 provides support for the heating tank 9, which can prevent structural fatigue damage caused by long-term severe vibration, such as support deformation and cracking of shell welds, which are potential safety hazards. Especially under high pressure and high temperature concentration conditions, the stable equipment structure can effectively reduce the risk of material leakage and ensure production safety.

[0039] When sealing is required for transmission pipe 10 and transmission pipe 2 16, when connecting plate 2 13 is moved, it rotates between fixing plate 2 12, causing connecting rod 1 14, which is rotatably connected at the right end, to move. Connecting rod 1 14 pushes fixing block 15, which is rotatably connected at the right end, to slide along the top of transmission pipe 10. At the same time, the inclined block 20 fixed to the outer wall of connecting plate 2 13 swings with connecting plate 2 13, squeezing the L-shaped plate 18 in contact with it, causing the L-shaped plate 18 to rotate on the left side of the top of mounting plate 11. When the L-shaped plate 18 rotates, it pushes spring 3 19. After compression, the fixing block 15 slides to contact the connecting rod 17 and then locks the connecting rod 17 in place through the slot on the outer wall. The L-shaped plate 18 is reset by the spring 19 and the connecting plate 13 is fixed, thus achieving a sealed connection between the transmission pipe 10 and the transmission pipe 16. When disassembly is required, the L-shaped plate 18 is moved to both sides first, and then the connecting plate 13 is moved to drive the connecting rod 14 to move towards the square box, thereby separating the fixing block 15 from the connecting rod 17 and achieving the disassembly effect.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
