Description

Technical Field

[0001] This utility model relates to the field of refining equipment technology, specifically a vacuum decompression concentrator. Background Technology

[0002] In many industrial sectors such as chemical, pharmaceutical, and food processing, material concentration is a common production step used to remove moisture or other solvents from materials, increasing their concentration to meet the requirements of subsequent processing or product storage. Vacuum vacuum concentration technology is widely used due to its significant advantages, such as achieving concentration at lower temperatures and effectively protecting heat-sensitive substances. However, existing vacuum concentrators still face some problems that urgently need to be addressed during actual operation.

[0003] On the one hand, during material concentration, uniform heating is a key factor affecting the concentration effect and product quality. Due to limitations in the heating and stirring methods within the concentration tank, localized overheating or uneven heating can easily occur. Localized overheating can lead to the decomposition and deterioration of the active ingredients in the material, affecting product quality; while uneven heating can cause some materials to be over-concentrated and others under-concentrated, resulting in uneven product concentration, reduced production efficiency, and lower product qualification rate. On the other hand, the material concentration process generates a large amount of high-temperature steam, which is usually directly released into the atmosphere, resulting in a significant waste of thermal energy. Therefore, a vacuum pressure reducing concentrator is proposed to address these issues. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vacuum depressurization concentrator includes a concentrator body and a base fixedly connected to the bottom of the concentrator body. The top of the concentrator body is provided with a stirring assembly for uniformly heating the material.

[0007] The stirring assembly includes a motor fixedly connected to the top of the concentration tank body. The output shaft of the motor is fixedly connected to a connecting rod. A mounting shell is fixedly connected to the outer side of the connecting rod. Elastic telescopic members are fixedly connected to both the left and right sides of the mounting shell.

[0008] The back of the concentration tank is equipped with a recovery component for waste heat recovery and utilization.

[0009] Furthermore, a material injection pipe and a connecting pipe are fixedly connected to the top of the concentration tank body, and a first discharge valve and a support foot are fixedly connected to the bottom of the concentration tank body.

[0010] Furthermore, the recycling assembly includes a first exhaust valve fixedly connected to the back of the concentration tank body. The exhaust end of the first exhaust valve is fixedly connected to a fixed pipe, and the other end of the fixed pipe is fixedly connected to a recycling box. A partition is fixedly connected to the inner side of the recycling box, and heat-conducting fins are fixedly connected to the inner side of the partition.

[0011] Furthermore, the recycling bin is fixedly connected to the top of the base, a second exhaust valve is fixedly connected to the left side of the recycling bin, a feed valve is fixedly connected to the right side of the recycling bin, a feed pipe is fixedly connected to the feed end of the feed valve, and a second discharge valve is fixedly connected to the bottom of the recycling bin.

[0015] Furthermore, the scraper has an installation port on its inner side, and the stirring paddles on the left and right sides are respectively fixedly connected to the inner side of the corresponding installation port.

[0016] Compared with the prior art, the present invention provides a vacuum concentrator with the following advantages:

[0017] This vacuum depressurization concentrator uses a scraper that moves in a circular motion along the inner wall of the concentrator tank to promptly remove material adhering to the tank wall, preventing scale buildup and ensuring even heat transfer. Simultaneously, a stirring paddle thoroughly agitates the material inside, causing it to tumble and mix continuously, preventing localized overheating or uneven heating. Furthermore, the high-temperature steam generated by the concentrator tank enters the recovery tank through the first exhaust valve and a fixed pipe. In the recovery tank, the design of baffles and heat-conducting fins increases the heat transfer area and efficiency, allowing the heat from the high-temperature steam to be quickly and effectively transferred to the space below the baffles. The material to be preheated enters this space through the feed pipe and feed valve, making full contact with the area that has undergone heat transfer, absorbing heat and increasing its temperature, thus achieving waste heat recovery and utilization.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3 The vacuum decompression concentrator in this embodiment includes a concentrator body 1 and a base 2 fixedly connected to the bottom of the concentrator body 1. The top of the concentrator body 1 is provided with a stirring assembly for uniformly heating the material.

[0024] Please see Figure 1 In this embodiment, the stirring assembly includes a motor 3 fixedly connected to the top of the concentration tank body 1. The output shaft of the motor 3 is fixedly connected to a connecting rod 4. A mounting shell 5 is fixedly connected to the outer side of the connecting rod 4. Elastic telescopic members 6 are fixedly connected to both the left and right sides of the mounting shell 5. Scrapers 7 are fixedly connected to the opposite ends of the elastic telescopic members 6 on both sides. A stirring paddle 8 is fixedly connected to the inner side of the scraper 7.

[0025] The back of the concentration tank body 1 is provided with a recovery assembly for waste heat recovery and utilization. The recovery assembly includes a first exhaust valve 13 fixedly connected to the back of the concentration tank body 1. The exhaust end of the first exhaust valve 13 is fixedly connected to a fixed pipe 14. The other end of the fixed pipe 14 is fixedly connected to a recovery box 15. A partition 16 is fixedly connected to the inner side of the recovery box 15. A heat-conducting fin 17 is fixedly connected to the inner side of the partition 16.

[0026] Specifically, the top of the concentration tank body 1 is fixedly connected to a feeding pipe 9 and a connecting pipe 10, and the bottom of the concentration tank body 1 is fixedly connected to a first discharge valve 11 and a support leg 12.

[0027] It should be noted that the injection pipe 9 is used to inject the material to be concentrated into the concentration tank body 1. Its pipe diameter and material should be reasonably selected according to the properties of the material to ensure that the material can enter the tank smoothly and safely.

[0028] Specifically, the recycling bin 15 is fixedly connected to the top of the base 2, a second exhaust valve 18 is fixedly connected to the left side of the recycling bin 15, a feed valve 19 is fixedly connected to the right side of the recycling bin 15, a feed pipe 20 is fixedly connected to the feed end of the feed valve 19, and a second discharge valve 21 is fixedly connected to the bottom of the recycling bin 15.

[0029] It should be noted that the second exhaust valve 18 is used to discharge the gas remaining in the recovery tank 15 after the waste heat has been utilized.

[0030] Specifically, the second exhaust valve 18 is located above the partition 16, and the feed valve 19 is located below the partition 16.

[0031] It should be noted that after the high-temperature gas enters the recovery box 15 from the concentration tank body 1, it will accumulate in the space above the partition 16. The second exhaust valve 18 is set here to discharge the gas in time and maintain the pressure stability in the recovery box 15. The feed valve 19 is located below the partition 16, so that the material to be preheated can directly enter the space below the partition 16 and fully contact the heat transferred through the partition 16 and the heat-conducting fins 17 to achieve efficient waste heat utilization.

[0032] Specifically, the top of the base 2 is provided with a guide groove, which is located directly below the first discharge valve 11, and the front of the base 2 is provided with a receiving recess that is compatible with the second discharge valve 21.

[0033] It should be noted that when the concentrated material is discharged from the first discharge valve 11, the guide chute can guide the material to flow in a predetermined direction, preventing the material from accumulating on the top of the base 2. The receiving recess provides space for the installation and operation of the second discharge valve 21, and also facilitates placing the container that collects the material after waste heat preheating in a suitable position.

[0034] Specifically, each of the four corners of the base 2 is fixedly connected to a movable wheel, and each movable wheel is equipped with a brake.

[0035] Specifically, the scraper 7 has an installation port on its inner side, and the stirring paddles 8 on the left and right sides are respectively fixedly connected to the inner side of the corresponding installation port.

[0036] The working principle of the above embodiments is as follows:

[0037] When the material concentration operation begins, the motor 3, which is fixedly connected to the top of the concentration tank body 1, is first started. The output shaft of the motor 3 begins to rotate, driving the connecting rod 4, which is fixedly connected to it, to rotate together. The mounting shell 5, which is fixedly connected to the outside of the connecting rod 4, rotates accordingly. The elastic telescopic parts 6 on the left and right sides of the mounting shell 5 move in a circular motion under the drive of the mounting shell 5. Since the elastic telescopic parts 6 have a certain elasticity, during the rotation, the elastic telescopic parts 6 will adjust their extension and contraction according to the centrifugal force and the resistance of the material, thereby driving the scraper 7, which is fixedly connected to the opposite end of the elastic telescopic parts 6, to move in a circular motion along the inner wall of the concentration tank body 1. During the movement, the scraper 7 can continuously scrape off any material that may be attached to the inner wall of the concentration tank body 1, preventing the material from scaling on the tank wall and ensuring that heat can be evenly transferred to the material. At the same time, the stirring paddle 8, which is fixedly connected to the inner side of the scraper 7, rotates together with the scraper 7. The stirring paddle 8 fully stirs the material in the concentration tank body 1, causing the material to continuously roll and mix in the tank, thereby achieving uniform heating of the material.

[0038] During the material concentration process, high-temperature steam is generated inside the concentration tank 1. This high-temperature steam is discharged through the first exhaust valve 13 fixedly connected to the back of the concentration tank 1 and enters the fixed pipe 14 fixedly connected to the exhaust end of the first exhaust valve 13. The high-temperature steam enters the recovery box 15 fixedly connected to the other end of the fixed pipe 14. After entering the recovery box 15, the high-temperature steam will accumulate in the space above the partition 16. The heat in the high-temperature steam is transferred to the space below the partition 16 through the partition 16 and the heat-conducting fins 17. At the same time, the material to be preheated enters the space below the partition 16 in the recovery box 15 through the feed pipe 20 and the feed valve 19. The material below the partition 16 comes into full contact with the heat transferred through the partition 16 and the heat-conducting fins 17, and its temperature rises after absorbing the heat, realizing the recovery and utilization of waste heat. The temperature of the preheated material increases, which can reduce the heating energy consumption in the subsequent process and improve the energy utilization efficiency of the entire production process.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
