Description

Technical Field

[0001] This invention belongs to the field of chemical equipment technology, specifically referring to a continuous sublimation device. Background Technology

[0002] Sublimation refers to the physical process by which a solid substance transforms directly into a gaseous state under certain temperature and pressure conditions, bypassing a liquid phase. Utilizing the properties of sublimation, the separation, purification, and property control of solid materials can be achieved. Therefore, sublimation equipment is widely used in chemical, fine chemical, pharmaceutical, agrochemical, and materials preparation fields. Generally, a sublimation device refers to equipment capable of causing solid raw materials to sublimate under controlled temperature, pressure, and atmosphere conditions and collecting the sublimation products.

[0003] Existing sublimation devices mostly employ intermittent operation, promoting sublimation of solid raw materials through overall or localized heating in a vacuum or inert gas environment. However, in practical applications, these devices generally suffer from incomplete sublimation or slow sublimation rates. On the one hand, solid raw materials are prone to agglomeration, sintering, or localized melting during sublimation, leading to a rapid reduction in the effective sublimation interface and hindering the sublimation process. On the other hand, regions rich in sublimate molecules tend to form near the sublimation interface, restricting molecule diffusion and thus reducing the overall sublimation driving force. Furthermore, the temperature field and material distribution inside the sublimation chamber are often uneven, further affecting sublimation efficiency and process stability.

[0004] Meanwhile, traditional sublimation devices rely on a single heating method and static material state, making it difficult to achieve continuous operation of the sublimation process. This results in low equipment utilization, high energy consumption, and inconvenience in cleaning and maintenance. Summary of the Invention

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The gas delivery mechanism can effectively destroy the local saturated boundary layer formed at the sublimation interface after water vapor and nitrogen enter the sublimation chamber in the early stage of sublimation, thus preventing the sublimation molecules from accumulating near the solid surface and inhibiting subsequent sublimation. This solves the problem of the sublimation rate decaying rapidly over time, making the sublimation process more stable and continuous.

[0017] (2) The lifting assembly is set up so that the solid raw materials and porous ceramic particles are continuously lifted and turned by the arc-shaped shovel plate, so that the solid raw materials are dispersed and attached to the surface of the porous ceramic particles in a thin layer, effectively reducing the direct contact between raw material particles. Even under conditions close to the softening temperature, it can significantly reduce the occurrence of agglomeration, sintering and agglomeration.

[0018] (3) The dynamic movement formed by the metal mesh, the arc-shaped shovel and the porous ceramic particles causes the solid raw material to continuously undergo "drop-collision-redispersal" during the sublimation process. The inert surface after sublimation is continuously peeled off, and new high-energy surfaces are continuously exposed, thereby avoiding the formation of "sublimation dead layer" and significantly increasing the number of effective sublimation interfaces per unit volume.

[0019] (4) Porous ceramic particles have good thermal stability and thermal buffering capacity. During the feeding process, they are fully mixed with solid raw materials and participate in heat exchange, so that the heat is evenly distributed in the sublimation chamber, avoiding the problems of local overheating or insufficient local temperature rise.

[0020] (5) By using a second vacuum pump to extract and collect the sublimation gas and inert gas together after sublimation, and because the solid raw material is supported and turned over by porous ceramic particles instead of being directly blown by violent airflow, the risk of dust being carried into the gas phase is significantly reduced, which is conducive to obtaining sublimation products with higher purity.

[0021] (6) The dust removal components are set up so that the airflow and rotating parts can clean the sublimation chamber inner wall, metal mesh, pipes and other areas that are prone to dust accumulation online. At the same time, the shovel head removes the attached materials, which effectively reduces the frequency of downtime for disassembly and cleaning, extends the continuous operation time of the device and reduces maintenance costs.

The heating wire 47 is installed at the bottom of the interior of the sealed generating chamber 46.

[0034] The dust removal assembly 4 includes a fan 51, a second output pipe 52, a sixth solenoid valve 53, a third output pipe 54, a seventh solenoid valve 55, a dust collection box 56, a filter bag 57, and an air outlet 58. The fan 51 is fixedly installed on the side wall of the sublimation chamber 9. The output end of the fan 51 is connected to one end of the second output pipe 52, and the other end of the second output pipe 52 is connected to the upper end of the fixed pipe 25. The sixth solenoid valve 53 is installed on the end of the second output pipe 52 near the fixed pipe 25.

[0036] In practical use, open the sealing cap 11, pour the solid raw material into the sublimation chamber 9 through the feed port 10, then tighten the sealing cap 11 onto the feed port 10, close the first solenoid valve 31 and the second solenoid valve 32, start the first vacuum pump 41, open the fourth solenoid valve 45 to extract the air from the sublimation chamber 9, then start the heating wire 47, open the fifth solenoid valve 50 to heat the water in the sealed generating chamber 46, thereby generating water vapor. Then open the pressure reducing valve 40 and the third solenoid valve 39, and the nitrogen compressed in the nitrogen storage tank 37 enters the fixed pipe 25 through the gas delivery pipe 38. Then open the second solenoid valve 32, and by controlling the pressure reducing valve 40, a small amount of water vapor and nitrogen are released through the first solenoid valve on the second turntable 24. Turntable 23 is introduced into sublimation chamber 9. The inert gas is not merely used as a protective gas, but as a "sublimation atmosphere modulation medium." Water vapor, as a gas with a high diffusion coefficient, dilutes the sublimate molecules at the sublimation interface, reducing the effective partial pressure of the sublimate at the interface and forming a larger partial pressure gradient, thus promoting the detachment of sublimate molecules from the solid phase surface. Subsequently, the second solenoid valve 32, pressure reducing valve 40, third solenoid valve 39, fifth solenoid valve 50, and heating wire 47 are closed, and heating element 21 is activated. Simultaneously, the output end of motor 27 rotates, driving the first bevel gear 28 to rotate. The rotation of the first bevel gear 28 drives the rotation of the second bevel gear 29, which in turn drives the rotation of the second drive tube 26, which in turn drives the first turntable 23 to rotate. The rotation of the first turntable 23 drives the first drive tube 15 to rotate, which in turn drives the arc-shaped connecting plate 16 to rotate. The rotation of the arc-shaped connecting plate 16 drives the drive ring 17 to rotate, which in turn drives the metal mesh 18 to rotate. The rotation of the metal mesh 18 drives the arc-shaped shovel plate 19 to rotate, thus scooping up the solid raw material and porous ceramic particles 22 from the bottom of the sublimation chamber 9. As the arc-shaped shovel plate 19 rotates, the solid raw material and porous ceramic particles 22 are thrown down in the hollow, which significantly increases the sublimation rate, greatly reduces the agglomeration and sintering of the solid raw material, and makes the temperature field significantly more uniform. After sublimation is completed, the first solenoid valve 31 and the eighth solenoid valve 60 are opened, and the second vacuum pump 42 is started. The sublimation is then carried out by the second vacuum pump 42. The sublimated gas and nitrogen in chamber 9 are extracted and collected from the outlet pipe 44. Finally, the opening and closing door 61 is opened to collect the porous ceramic particles 22 and fertilizer. When it is necessary to clean the sublimation chamber 9 and its pipes, the eighth solenoid valve 60, the fourth solenoid valve 45 and the second solenoid valve 32 are closed, and the first solenoid valve 31 and the seventh solenoid valve 55 are opened. At the same time, the first bevel gear 28 and the fan 51 are started. The dust in the sublimation chamber 9, the metal mesh 18, the second drive pipe 26 and the connecting pipe 59 is collected by airflow onto the filter bag 57 in the dust collection box 56. The shovel head 20 is used to clean the unreacted material attached to the inner wall of the sublimation chamber 9. The above is the overall working process of the present invention. This step can be repeated for the next use.
