Description

Technical Field

[0001] This utility model relates to the field of powder production technology, and in particular to a drying device for wettable powders. Background Technology

[0002] Pesticide formulations mainly include powders, wettable powders, emulsifiers, emulsifiable concentrates, suspension concentrates, granules, and aqueous solutions. In my country, the vast majority of active ingredients are processed into wettable powders and emulsifiable concentrates. Among these, wettable powders are a relatively new and stable pesticide formulation due to their ease of storage and transportation. The production of wettable powders includes processes such as mixing, pulverizing, and packaging. The pulverizing process uses an air jet mill, which requires a large amount of compressed air. This compressed air is mostly prepared by a compressed air dryer to ensure its dryness. The prepared compressed air is stored in a storage tank for later use. However, some compressed air dryers still produce compressed air containing some moisture and oil vapor, which can affect the pulverization effect of wettable powders, resulting in moisture content in the wettable powder. Therefore, further drying is necessary.

[0003] When drying powders, most existing drying devices dry the powders by placing them in multiple layers of trays inside an oven. However, in this type of oven, the powders are in a static state during the drying process and cannot be dynamically dispersed. This results in uneven heating of the powders, causing the powders in the thicker areas to not be completely dried, while the powders on the outer edges are prone to scorching.

[0004] Therefore, a drying device for wettable powders is needed to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the fact that in the above or existing technologies, powders are mostly statically placed in multiple layers during the drying process, resulting in uneven heating, this utility model is proposed.

[0032] Example 1

[0033] Reference Figures 1 to 5 This is the first embodiment of the present invention. This embodiment provides a drying device for wettable powders, which can realize the dynamic dispersion of powders and, with the help of a ring and a spiral double ventilation pipe, enables the powders to fully contact with hot air. It includes: a drying box 100 and a fixing frame 101 disposed inside it.

[0034] The material guiding mechanism 200 includes a material guiding plate 201 disposed on the top of the fixed frame 101, and a material guiding plate 202 disposed around the outer surface of the fixed frame 101.

[0035] The drive mechanism 300 is located on the lower side of the drying chamber 100 and connected to the guide plate 201 to provide the power required for rotation;

[0036] The ventilation assembly 400 includes a first ventilation pipe 401 and a second ventilation pipe 402 that are interconnected. The first ventilation pipe 401 is disposed above the guide plate 201 and is fixedly connected to the inner wall of the drying chamber 100. The second ventilation pipe 402 is connected to the guide plate 202. The first ventilation pipe 401 and the second ventilation pipe 402 respectively dry the powder above the guide plate 201 and the guide plate 202.

[0037] And a blower 500 is provided on the outside of the drying chamber 100, the output end of the blower 500 is fixedly connected to the interior of the drying chamber 100 and communicates with the first ventilation pipe 401.

[0038] In use, the powder to be dried is added to the inside of the drying chamber 100 and placed above the guide plate 201. At the same time, the drive mechanism 300 is started, driving the guide plate 201 to rotate, causing the powder above the guide plate 201 to be flung outwards. Due to gravity, the flung powder falls and lands on the guide plate 202, slowly descending. Simultaneously, the blower 500 is started, generating hot air for drying, which is delivered to the ventilation assembly 400 through the connecting pipe 501. The hot air inside the first ventilation pipe 401 makes initial contact with the flung powder, quickly removing surface moisture. In addition, the hot air inside the second ventilation pipe 402 can continuously blow air onto the upper surface of the guide plate 202, thereby performing a secondary drying process on the slowly falling powder. This achieves drying of the powder during the dynamic falling process, avoiding the situation where the outer layer is scorched and the inner layer is not dry.

[0039] Example 2

[0040] Reference Figures 1 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, the top of the drying oven 100 is provided with a feed inlet 102, which corresponds to the guide plate 201. The feed inlet 102 is detachably provided with a feed pipe 103 inside, and the drying oven 100 is provided with a discharge outlet 104 below the guide plate 202.

[0041] In use, one end of the feed pipe 103 is connected to the hopper, and the other end is threaded to the feed port 102. It is easy to disassemble after drying. The feed port 102 is equipped with a limiting ring to limit the feed pipe 103, preventing the feed pipe 103 from being screwed in too much and affecting the use of the guiding mechanism 200.

[0042] Specifically, the top of the guide plate 201 is tapered, and the bottom of the guide plate 201 is rotatably connected to the top of the fixed frame 101.

[0043] Because the guide plate 201 is designed with a top cone shape, it uses gravity to initially disperse the powder, avoiding the accumulation of powder at the landing point, and laying the foundation for subsequent rotary dispersion.

[0044] Specifically, the guide plate 202 is spirally arranged and is arranged in the opposite direction of rotation to the guide plate 201. The top of the guide plate 202 is below the top of the guide plate 201, and the bottom of the guide plate 202 extends through the discharge port 104 to the bottom of the drying chamber 100.

[0045] By using the spiral arrangement of the guide plate 202, when the powder is dispersed and falls in all directions through the guide plate 201, the guide plate 202 can make the powder fall slowly in the spiral direction, prolonging the residence time of the powder in the drying chamber 100 and avoiding insufficient drying caused by rapid powder falling.

[0046] Specifically, the drive mechanism 300 includes a motor 301 fixedly connected to the bottom of the drying oven 100. The output end of the motor 301 is fixedly connected to a connecting shaft 302, and the other end of the connecting shaft 302 extends into the interior of the fixed frame 101 and is fixedly connected to the bottom end of the guide plate 201.

[0047] When the motor 301 starts, it drives the connecting shaft 302 to rotate, and drives the guide plate 201 to rotate. The rotation direction of the guide plate 201 is opposite to the spiral direction of the guide plate 202, causing the powder to be thrown around. At this time, the powder falls above the guide plate 202 under the action of the guide plate 201, and slowly falls down with the spiral direction of the guide plate 202, and is finally discharged from the outlet 104.

[0048] Specifically, the first ventilation pipe 401 is arranged in a ring-shaped spiral and is located above the guide plate 201. The second ventilation pipe 402 is spirally arranged and is fixedly connected to the spirally arranged guide plate 202. Several sets of first ventilation openings 403 and second ventilation openings 404 are respectively opened on the first ventilation pipe 401 and the second ventilation pipe 402. The first ventilation openings 403 and the second ventilation openings 404 are both inclined. The first ventilation openings 403 are gradually inclined towards the inner wall of the drying chamber 100. The inclination direction of the second ventilation openings 404 is the same as the spiral direction of the guide plate 202. One end of the first ventilation pipe 401 is fixedly connected to the blower 500 and the connecting pipe 501. The other end of the first ventilation pipe 401 is fixedly connected to the second ventilation pipe 402 by an arc-shaped pipe 405.

[0049] With the combined use of the first ventilation pipe 401 and the first ventilation port 403, when hot air enters the interior of the first ventilation pipe 401 through the connecting pipe 501, the hot air inside is blown out through the first ventilation port 403 to dry the powder and blow the dispersed powder to the position of the guide plate 202. In addition, excess hot air will enter the interior of the second ventilation pipe 402 through the arc-shaped pipe 405 and be blown out through the second ventilation port 404. It will then be blown towards the moving powder along the spiral trajectory of the guide plate 202 to dry the powder again.

[0050] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
