Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and specifically to a drying device for composite materials. Background Technology

[0002] Composite materials are materials composed of two or more materials with different properties, combined through physical or chemical methods to create new properties at the macroscopic (microscopic) level. The various materials complement each other in terms of performance, producing a synergistic effect, so that the overall performance of the composite material is superior to that of the original constituent materials and meets various requirements. During the manufacturing process, composite materials are extruded and cooled with water to form pellets. The pellets contain a lot of moisture and cannot be used for direct processing. The moist composite material pellets need to be dried. When drying composite material pellets in the existing technology, the pellets tend to pile up or clump together, making it difficult to efficiently turn and dry the pellets. This can easily lead to insufficient drying of the composite material pellets and thus low drying efficiency. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solution: A drying device for composite materials includes: a box body, the upper end of which is provided with a feed inlet and the interior is provided with a first drying chamber and a second drying chamber from top to bottom. The feed inlet is connected to the first drying chamber. The first drying chamber includes a first cavity, a sealing mechanism, and a pressure relief valve. The side wall of the cavity body is provided with an exchange hole. A first drying pipe is provided on the outside of the first drying chamber. The sealing mechanism is used to separate the first drying chamber and the second drying chamber. The second drying chamber includes a second cavity and a drying cylinder rotatably disposed in the second cavity. A stirring mechanism and a drying mechanism are respectively provided at both ends of the drying cylinder. The stirring mechanism includes a baffle plate rotatably disposed in the drying cylinder and a drive motor disposed on the outside of the box body. The drive motor drives the baffle plate to rotate in the drying cylinder through a transmission component. The drying mechanism includes a drying tray inserted into the drying cylinder and a second drying pipe connected to the drying tray.

[0005] In a further improvement, the sealing mechanism includes a partition plate, a discharge hole, and a sealing cylinder. The piston rod of the sealing cylinder is fixedly provided with a sealing plate, and the sealing plate is slidably disposed within the partition plate to seal the discharge hole.

[0006] As a further improvement, a feeding port is provided at the upper end of the drying cylinder, and the feeding port is correspondingly provided with the discharge port of the sealing mechanism.

[0007] As a further improvement, guide ramps are provided on both sides of the feeding port.

[0008] As a further improvement, an isolation mesh plate is provided inside the drying cylinder on the side near the drying tray.

[0009] In a further improvement, a support mechanism is provided inside the second drying chamber, and the support mechanism abuts against the lower side of the drying cylinder.

[0010] In a further improvement, the side of the drying cylinder equipped with the stirring mechanism extends through the side wall of the box body and has a discharge port at the lower end.

[0011] Compared with the prior art, the present invention has the following advantages: through the staged drying design of the first drying chamber and the second drying chamber, the material is first pre-dried in the first drying chamber to effectively remove most of the moisture, and then deep dried in the second drying chamber to ensure that the material reaches the required degree of dryness, which significantly improves drying efficiency and quality.

[0018] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0019] Example 1

[0020] A composite material drying device includes: a housing 1, with a feed inlet 11 at the upper end and a first drying chamber 2 and a second drying chamber 3 arranged from top to bottom inside the housing 1. The feed inlet 11 communicates with the first drying chamber 2. The first drying chamber 2 includes a first cavity 21, a sealing mechanism 22, and a pressure relief valve 23. An exchange hole 211 is provided on the side wall of the cavity 21. A drying pipe 24 is provided on the outside of the first drying chamber 2. The sealing mechanism 22 is used to separate the first drying chamber 2 and the second drying chamber 3. The second drying chamber 3 includes a second cavity 31 and a rotating... A drying cylinder 32 is provided in the second cavity 31. A stirring mechanism 321 and a drying mechanism 322 are respectively provided at both ends of the drying cylinder 32. The stirring mechanism 321 includes a baffle plate 3211 rotatably disposed in the drying cylinder 32 and a drive motor 3212 disposed on the outside of the housing 1. The drive motor 3212 drives the baffle plate 3211 to rotate in the drying cylinder 32 through a transmission component. The drying mechanism 322 includes a drying tray 3221 inserted in the drying cylinder 32 and a drying pipe 3222 connected to the drying tray 3221.

[0021] like Figures 1-3 As shown, in actual use, the composite material to be dried is first fed into the feed inlet 11 at the top of the chamber 1. The material enters the first drying chamber 2. In the first chamber 21, hot air enters through the drying pipe 24 to perform preliminary drying on the material. The exchange hole 211 helps to regulate the circulation and distribution of hot air in the chamber, improving drying efficiency. The sealing mechanism 22 ensures the independence between the first drying chamber 2 and the second drying chamber 3, preventing cross-interference between hot air and material. At the same time, the pressure relief valve 23 monitors and adjusts the pressure in the chamber in real time to ensure a safe and stable drying environment. Through preliminary drying, the moisture in the material is effectively removed.

[0022] After initial drying, the sealing mechanism 22 automatically opens, and the material in the first drying chamber 2 falls into the drying cylinder 32 of the second drying chamber 3. The drive motor 3212 drives the baffle plate 3211 to rotate through the transmission components, causing the material to continuously tumble within the drying cylinder 32, ensuring uniform drying. Simultaneously, the drying tray 3221 and drying tube 3222 in the drying mechanism 322 further provide hot air for secondary deep drying of the material. This ensures that the material reaches the required degree of dryness, improving the quality of the final product.

[0023] This invention features a two-stage independent drying chamber design. First, the material is pre-dried in the first drying chamber 2, which effectively removes most of the moisture. Then, it is deeply dried in the second drying chamber 3, ensuring that the material reaches the required degree of dryness and significantly improving drying efficiency.

[0024] As a further preferred embodiment, the sealing mechanism 22 includes a partition plate 221, a discharge hole 222, and a sealing cylinder 223. The piston rod of the sealing cylinder 223 is fixedly provided with a sealing plate 2231, and the sealing plate 2231 is slidably disposed in the partition plate 221 to seal the discharge hole 222.

[0025] Specifically, the piston rod of the sealing cylinder 223 is fixedly connected to the sealing plate 2231, which can slide within the partition plate 221 to control the opening and closing of the discharge hole 222. When the sealing cylinder 223 drives the piston rod to extend, the sealing plate 2231 blocks the discharge hole 222, ensuring the independence of the first drying chamber 2; when the piston rod retracts, the sealing plate 2231 slides away from the discharge hole 222, and the material slides into the second drying chamber 3. This structure enables precise control of the material drying process.

[0026] As a further preferred embodiment, the upper end of the drying cylinder 32 is provided with a feeding port 324, which is correspondingly provided with the discharge port of the sealing mechanism 22, and guide ramps 3241 are provided on both sides of the feeding port 324.

[0027] Specifically, the feeding port 324 is set to correspond to the discharge port of the sealing mechanism 22 to ensure that the material can smoothly enter the second drying chamber 3 from the first drying chamber 2. The guide ramps 3241 set on both sides can guide the material smoothly into the drying cylinder 32 to prevent the material from accumulating or scattering at the feeding port 324.

[0028] As a further preferred embodiment, an isolation mesh plate 323 is provided inside the drying cylinder 32 on the side near the drying tray 3221. The isolation mesh plate 323 can effectively prevent the material from directly contacting the drying tray 3221 during the drying process, avoid the material from adhering to the drying tray 3221, and at the same time allow hot air to pass through evenly, thereby improving drying efficiency.

[0029] As a further preferred embodiment, a support mechanism 33 is provided in the second drying chamber 3, and the support mechanism 33 abuts against the lower side of the drying cylinder 32.

[0030] Specifically, the support mechanism 33 provides stable support for the drying cylinder 32, ensuring that it remains balanced during rotation and material tumbling, avoiding swaying caused by uneven material weight distribution or centrifugal force generated by rotation, which helps extend the service life of the drying cylinder 32 and ensures the smooth operation of the drying process.

[0031] As a further preferred embodiment, the drying cylinder 32 is provided with a stirring mechanism 321 on one side that penetrates the side wall of the box body 1 and has a discharge port 325 at its lower end.

[0032] Specifically, a sealing mechanism is provided between the drying cylinder 32 and the box body 1, and the discharge port 325 located on the outside facilitates the discharge of the dried material, simplifying the operation process and improving production efficiency.

[0033] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
