Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically a double cone vacuum dryer with crushing function. Background Technology

[0002] A vacuum dryer is a device that uses the low pressure of a vacuum environment to lower the boiling point of materials and achieve low-temperature drying. It is used in fields such as pharmaceuticals, chemicals, and food where there are high requirements for drying heat-sensitive materials. During the drying process, the equipment heats the material in the inner chamber through jacket heating, while a vacuum pump continuously extracts air from the inside of the chamber, allowing the material to lose moisture at a lower temperature.

[0003] Although vacuum dryers can achieve uniform heating under low-temperature vacuum conditions, in the actual drying process, materials may have poor flowability due to their own properties. In particular, some powdery or highly viscous materials are prone to local agglomeration or even overall clumping after being heated and dehydrated. Once large particles clump together, it will not only lead to uneven drying but also affect the moisture content of the final product.

[0004] Therefore, there is an urgent need for a double-cone vacuum dryer with crushing function to solve the above-mentioned technical defects. Utility Model Content

[0005] The purpose of this invention is to provide a double cone vacuum dryer with crushing function to solve the problems mentioned in the background art, such as poor material flowability, easy agglomeration, and poor drying effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-cone vacuum dryer with crushing function, comprising a base plate and a frame. A set of frames is fixed on each of the top two sides of the base plate. An outer casing is mounted on the middle of the frame. An inner liner is provided inside the outer casing. A jacket surrounds the inner liner. The frame is covered with a support casing. A crushing blade is inserted through the left side of the outer casing. A vacuum filter cover is installed at the front end of the crushing blade. A driving device is installed inside the frame. The driving device drives the crushing blade to rotate through a transmission belt and a transmission sprocket. A blade is fixed at the front end of the crushing blade.

[0007] As a further technical solution of this utility model, the blade is a double conical blade structure, which is fixed to the front end of the crusher by screws, and the blade is located in the middle of the inner liner.

[0011] As a further technical solution of this utility model, a frame side door is installed on the left side of the frame for maintenance of the drive components.

[0012] As a further technical solution of this utility model, a feed inlet cover is installed at the top of the inner liner, a breather is installed at the top of the feed inlet cover, a quick-install sanitary ball valve is installed at the breather, and an air vent ball valve is also installed at the feed inlet cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the double cone vacuum dryer with crushing function not only eliminates agglomeration and accelerates drying, but also avoids powder backflow and vacuum blockage, and avoids vacuum leakage or cross-contamination.

[0014] (1) By setting up a drive device, crushing knife and blade, the material is dispersed by the high-speed reamer in the cone during the drying process, avoiding the impact of agglomeration on drying uniformity and efficiency, thereby achieving the purpose of efficient dehydration and stable drying of agglomerated materials in a low-pressure and low-temperature environment in the double cone vacuum dryer.

[0015] (2) By setting up a vacuum tube, a vacuum flange bellows, a vacuum gauge and a vacuum filter cover, a more thorough and non-clogging gas discharge effect can be achieved during the vacuuming process. The internal pressure of the cavity is monitored in real time and nitrogen protection is provided, thereby ensuring a stable vacuum state without affecting the smooth flow of gas, avoiding powder backflow, contamination of the vacuum system and blockage of the outlet.

[0016] (3) By setting up a feed inlet cover, a breather, a quick-install sanitary ball valve, a discharge port, a handwheel-type butterfly valve and a drain ball valve, the sealing performance of the whole machine is improved, and high sealing control of the feed inlet and outlet is achieved throughout the drying process, avoiding vacuum leakage or cross-contamination, ensuring a stable drying environment, and suitable for applications in industries with high cleanliness requirements such as pharmaceuticals and fine chemicals.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 Figure 1-4 An embodiment of this utility model is provided: a double cone vacuum dryer with crushing function, including a base plate 8 and a frame 6. A set of frames 6 is fixed on each of the top two sides of the base plate 8. A tank outer casing 3 is mounted in the middle of the frame 6. An inner liner 1 is provided inside the tank outer casing 3. A jacket 2 surrounds the inner liner 1. The frame 6 is covered with a support outer casing 7. A crushing blade 19 is installed on the left side of the tank outer casing 3. A vacuum filter cover 11 is installed at the front end of the crushing blade 19. A driving device 22 is installed inside the frame 6. The driving device 22 drives the crushing blade 19 to rotate through a transmission belt and a transmission sprocket. A blade 25 is fixed at the front end of the crushing blade 19. The blade 25 is a double cone blade structure and is fixed to the front end of the crushing blade 19 by screws. The blade 25 is located in the middle of the inner liner 1.

[0024] Specifically, such as Figure 1 and Figure 4As shown, the drive device 22 is installed on the left side of the frame 6. It drives the crusher 19 to rotate through the transmission belt and sprocket, which in turn drives the double cone structure blade 25 fixed at its front end to rotate at high speed. The blade 25 achieves high-frequency shearing in the mixing chamber, which can break and disperse the agglomerated particles that have been generated, thereby enhancing the fluidity of the material. During the drying process, the material is dispersed by the high-speed reamer in the cone, resulting in efficient dehydration.

[0025] The left side of the jacket 2 is connected to the inlet pipe 20 and the return pipe 21. The bottom end of the jacket 2 is connected to the drain outlet 23. The right side of the outer casing 3 of the tank is provided with a vacuum tube 13. A vacuum flange-type corrugated pipe 16 is installed on the right side of the vacuum tube 13. A vacuum gauge 14 is installed at the connection between the vacuum flange-type corrugated pipe 16 and the vacuum tube 13. A nitrogen pipe 17 is provided inside the vacuum tube 13. A platinum resistance sensor 15 is installed on the right side of the nitrogen pipe 17. The left side of the vacuum tube 13 extends into the outer casing 3 of the tank. A vacuum filter cover 11 is fixedly connected to the left side of the vacuum tube 13. There are three sets of vacuum filter covers 11. Each set of vacuum filter covers 11 is equipped with a filter cloth bag 24 at the front end.

[0026] Specifically, such as Figure 1 As shown, the vacuum tube 13 extends from the right side of the outer casing 3 of the tank to the inside. Its left end is fixedly connected to three sets of vacuum filter covers 11. Each set of vacuum filter covers 11 is equipped with a filter cloth bag 24 at the front end, which can effectively block powder particles from being drawn into the pipe, prevent filter cloth blockage and vacuum efficiency reduction. The vacuum flange bellows 16 is connected to the vacuum gauge 14 and the nitrogen pipe 17 to monitor the internal pressure of the cavity in real time and provide nitrogen protection to prevent powder backflow.

[0027] The top of the outer casing 3 is fixedly connected to the inlet cover 4, the bottom of the outer casing 3 is installed with the outlet 12, the outlet 12 is installed with a handwheel clamp butterfly valve 5, the left side of the frame 6 is installed with a frame side door 18 for maintenance of the drive components, the top of the inner liner 1 is installed with the inlet cover 4, the top of the inlet cover 4 is installed with a breather 10, the breather 10 is installed with a quick-install sanitary ball valve 9, and the inlet cover 4 is also installed with an empty ball valve 26.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the feed port cover 4 is located on the top of the outer casing 3 of the tank. The top is equipped with a breather 10 and a quick-install sanitary ball valve 9 for feeding and breathing pressure differential regulation. The bottom discharges the dry material through a handwheel-operated clamp butterfly valve 5 and a discharge port 12. The vent ball valve 26 is used for final residual liquid or inert gas discharge control to avoid vacuum leakage or cross-contamination.

[0029] The computer software involved in the drive device 22 carrier in the technical solution is software technology known to those skilled in the art; it is merely applied to the aforementioned hardware carrier. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carrier, nor is it a key technical point of the invention.

[0030] Therefore, it can be seen that the "quick-install sanitary ball valve 9", "vacuum gauge 14", "platinum resistance sensor 15", "venting ball valve 26" and other items involved in this application are all physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of this application, in order to solve the corresponding technical problems to be solved by this application.

[0031] Working Principle: When this double-cone vacuum dryer with crushing function is running, the material to be dried is first added to the inner liner 1 through the feed inlet cover 4. During the feeding process, the quick-connect sanitary ball valve 9 and the breather 10 work together to achieve air pressure balance, preventing the introduction of moisture or contaminants from the outside air. After feeding is completed, the feed inlet cover 4 is sealed, and the vacuum system is activated. The vacuum tube 13 is connected to the vacuum flange-type bellows 16, with one end leading into the inner liner 1 and the other end connected to the vacuum gauge 14 and the vacuum filter hood 11. During the vacuuming process, the filter bag 24 inside the vacuum filter hood 11 filters out powder particles, preventing them from entering the vacuum tube 13 and causing blockage. Simultaneously, the vacuum gauge 14 monitors the internal negative pressure in real time to ensure a stable vacuum environment. The nitrogen pipe 17 can be used to introduce inert gas after vacuuming, improving the safety of the drying process. The material begins to heat under the heating action of the jacket 2. The left side of the jacket 2 is connected to the water inlet pipe 20 and the water return pipe 21, respectively. A drain port 23 is provided at the bottom for introducing and recovering heat. The liquid is cooled and the internal sediment is cleaned. The jacket 2 surrounds the inner tank 1 to achieve uniform heat transfer. The inlet cover 4 is fixedly installed on the top of the outer casing 3 of the tank and connected to the outlet 12 below. The outlet 12 is equipped with a handwheel-operated wafer-type butterfly valve 5 for sealing and controlling the discharge operation. The bottom is also equipped with a vent ball valve 26 for the final release of residual liquid or gas. While the heating and vacuuming process is in progress, the drive device 22 installed on the left side of the frame 6 is started, driving the transmission belt and sprocket to drive the crusher 19 to rotate. The front end of the crusher 19 is fixedly equipped with a double-cone blade 25. The blade 25 rotates at high speed inside the inner tank 1, continuously breaking and shearing the material to enhance the material flowability. After drying, the material is discharged by opening the handwheel-operated wafer-type butterfly valve 5 through the outlet 12. If necessary, the vent ball valve 26 can be opened first to discharge inert gas or residual water vapor. After the entire drying process is completed, the drive device 22 and other transmission parts can be maintained and inspected through the side door 18 of the frame.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
