Description

Technical Field

[0001] This application relates to the field of drying equipment technology, specifically a flash drying device. Background Technology

[0002] Flash dryers are a type of drying equipment commonly used in industries such as chemical, pharmaceutical, and food processing. Their advantage lies in their ability to quickly convert liquid materials into powdery or granular dry materials, thereby improving production efficiency and product quality.

[0003] The working principle of existing flash dryers is as follows: liquid material is evenly sprayed into the drying chamber through a high-speed rotating sprayer, while hot air is heated and delivered into the drying chamber. Inside the drying chamber, after the liquid material comes into contact with the hot air, the moisture evaporates rapidly under the action of high temperature, forming tiny granular or powdery dried material, which is finally discharged through the discharge port, completing the drying of the material. For example, Chinese utility model patent with publication number CN218155408U discloses a flash dryer with dust removal function. This device removes dust by setting a dust removal box inside the chamber and using the adsorption capacity of water.

[0004] However, in the implementation of the above technical solution, although the filtration effect can be achieved by setting the first filter layer and the second filter layer, and spraying dust into the box by the spraying component, in actual use, the dust and water mix and easily stick to the filter layer. After long-term use, a large amount of dust will accumulate, causing the filter layer to become clogged. This not only affects the dust removal effect, but also makes it difficult to discharge the dried material, affecting the original drying function.

[0005] Therefore, it is necessary to provide a flash drying device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a flash drying device that, by setting cleaning holes, cleans the filter screen in a timely manner, effectively preventing the filter screen from becoming clogged and affecting the drying process.

[0008] The technical solution adopted by this application to solve its technical problem is: a flash drying device, comprising:

[0009] A heated air supply assembly, wherein the heated air supply assembly is used to provide a heat source;

[0010] A feeding hopper, wherein the feeding hopper has a feeding port;

[0011] A drying assembly, which is connected to the feed hopper pipeline;

[0012] The drying assembly includes:

[0015] A filter screen is disposed inside the second drying chamber;

[0016] A cover plate, wherein the cover plate is disposed above the second drying chamber;

[0017] The discharge port is provided on the cover plate;

[0018] Cleaning hole, which is provided on the cover plate.

[0019] In the implementation of the technical solution of this application, by setting a first drying chamber and a second drying chamber, and setting a cleaning hole on the cover plate, when it is necessary to clean the filter screen, it is only necessary to open the cleaning hole to achieve this, thus preventing the filter screen from becoming clogged.

[0020] Furthermore, the heating and air supply assembly includes a blower, the output end of which is connected to a heating box, and a heater is installed inside the heating box, which is connected to a power source.

[0021] Furthermore, the first drying chamber is conical, and the bottom opening of the first drying chamber is smaller than the top opening.

[0022] Furthermore, a pressure valve is provided on the cover plate.

[0023] Furthermore, a flexible hose is provided between the feed hopper and the drying assembly.

[0024] The beneficial effects of this application are as follows: The flash drying device provided by this application has a first drying chamber and a second drying chamber, and a cleaning hole is provided on the cover plate. When it is necessary to clean the filter screen, it is only necessary to open the cleaning hole to achieve this, which prevents the filter screen from clogging. In addition, the first drying chamber is conical, and during the drying process, the material will slide down along its inner wall, thereby reducing accumulation.

[0025] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. A further detailed description of this application will be provided below with reference to the figures. Attached Figure Description

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] like Figures 1-2 As shown, this application provides a flash drying device for drying liquid materials. The device includes a heating and air supply assembly 1, which provides a heat source for the device to achieve the drying effect. The heating and air supply assembly 1 includes a blower 11, the output end of which is connected to a heating chamber 12. A heater 13 is installed inside the heating chamber 12 and is connected to a power source (not shown in the figure). After the power is turned on, the heater 13 heats the air inside the heating chamber 12 and supplies air through the blower 11.

[0035] The heating box 12 is connected to the feeding hopper 2, which is provided with a feeding port 21. The feeding hopper 2 is used to receive the material to be dried. When the material is liquid, the material to be dried can be sprayed into the feeding hopper 2 through a high-pressure nozzle, so as to spray the material to be dried evenly and improve the drying effect. The structure of the high-pressure nozzle can be referred to the invention patent with publication number CN117734110A, and will not be described in detail in this embodiment.

[0036] The feed hopper 2 is connected to a flexible hose 3, which is connected to a drying assembly 4. The drying assembly 4 receives the material to be dried from the feed hopper 2 and receives hot air from the heating and air supply assembly 1 to dry the material. Figure 1 As shown, the drying assembly 4 includes a connecting pipe 41, which is sealed to the hose 3. The other end of the connecting pipe 41 is provided with a first drying chamber 42, which is a cone with a bottom opening smaller than the top opening. During the drying process, some material will fall along the inclined surface of the first drying chamber 42, thus preventing it from sticking to its inner wall. After long-term drying, when it is necessary to remove the material deposited at the bottom, it is only necessary to disassemble any one end of the hose 3. Since the hose 3 can move laterally, it is not necessary to remove the entire hose 3, resulting in high disassembly and assembly efficiency.

[0037] A second drying chamber 43 is also provided on the first drying chamber 42. The second drying chamber 43 is cylindrical and is provided with a cover plate 44. The cover plate 44 is sealed to the second drying chamber 43 and is provided with a discharge port 45. During the drying process, the dried material, which is lighter in weight, will enter the second drying chamber 43 under the blowing of hot air. The material that is not yet dried, which has a higher water content and is heavier, will remain in the drying assembly 4. The discharge port 45 can be connected to a collection device to promptly discharge the dried material.

[0038] like Figure 2 As shown, in order to prevent some large particles that have not yet been dried from being mistakenly collected during the drying process, a filter screen 48 is provided in the second drying chamber 43. During the drying process, materials larger than the filter holes of the filter screen 48 cannot be discharged through the discharge port 45, but continue to dry.

[0039] like Figure 1 As shown, a cleaning hole 47 is provided on the cover plate 44. After the cleaning hole 47 is opened, a cleaning tool can be inserted to clean the filter screen 48 to prevent some particles from clogging the filter screen 48 and affecting the subsequent filtration effect. In order to prevent the internal pressure of the drying component 4 from being too high, a pressure valve 46 is also provided on the cover plate 44. When the internal pressure is too high, the pressure valve 46 will automatically open and release the pressure. After the internal pressure stabilizes, the pressure valve 46 will automatically close.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
