Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a pulverizing mechanism for a single-cone vacuum ribbon dryer. Background Technology

[0002] The single-cone spiral ribbon vacuum dryer features a single-cone tank design, offering a simple structure and convenient operation. The tank is made of sanitary-grade stainless steel, meeting GMP requirements, and is suitable for industries such as pharmaceuticals, biotechnology, chemicals, and food. The drying efficiency of the single-cone spiral ribbon vacuum dryer is 3-5 times that of a double-cone rotary vacuum dryer of the same specifications. Its unique stirring and heating method allows materials to fully contact the heat source in a short time, accelerating the moisture evaporation rate and achieving highly efficient drying. Simultaneously, the vacuum environment reduces the energy consumption required for material drying, resulting in significant energy savings compared to traditional drying methods. However, in current dryers on the market, the presence of moisture in the materials causes some materials to remain in a clump-like state throughout the drying process, making it difficult to completely dry these materials. Therefore, we propose a pulverizing mechanism for the single-cone vacuum ribbon dryer to address the aforementioned problems. Utility Model Content

[0003] The purpose of this invention is to provide a pulverizing mechanism for a single-cone vacuum ribbon dryer to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A pulverizing mechanism for a single-cone vacuum ribbon dryer includes a body, a transmission device, a mechanical seal, and pulverizing blades. The mechanical seal is externally fitted with a mounting shell, which is fixed to the body. One end of the mechanical seal is fixed to the inner wall of the body. The transmission device is mounted on the mechanical seal at the end furthest from the body. Several pulverizing blades are provided, each mounted on the mechanical seal at the end inside the body, and the blades rotate within the body.

[0006] According to the above technical solution, an output shaft is provided through the middle of the mechanical seal, and several crushing blades are symmetrically installed on the outer surface of the end of the output shaft.

[0007] According to the above technical solution, the output end of the transmission device is connected to one end of the output shaft, and the input direction and output direction of the transmission device are perpendicular to each other.

[0008] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0009] By setting up a transmission device, mechanical seal, and crushing blades, the transmission device changes the output direction, so that the output power acts on the crushing blades through the output shaft. This allows the crushing blades to contact and crush the material during the lifting and lowering process inside the machine, so that the lumpy material can be dried more thoroughly.

[0012] 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.

[0013] Please see Figure 1 The present invention provides the following technical solution:

[0014] A pulverizing mechanism for a single-cone vacuum ribbon dryer includes a body 4, a transmission device 1, a mechanical seal 2, and crushing blades 3. The mechanical seal 2 is installed inside a mounting shell, which is fixed to the outer surface of the body 4 by bolts. One end of the mechanical seal 2 is fixed to the inner wall of the body 4. The transmission device 1 is installed on the mechanical seal 2 at the end away from the body 4. An output shaft is provided through the middle of the mechanical seal 2. Several crushing blades 3 are symmetrically installed on the outer surface of one end of the output shaft and are rotatably disposed inside the body 4. The output end of the transmission device 1 is connected to the other end of the output shaft, and the input direction and output direction of the transmission device 1 are perpendicular to each other.

[0015] It should be further explained that the output shaft is driven by the transmission device 1 and the output direction is changed, so that the crushing blades 3 placed in the machine body 1 rotate synchronously with the rotation of the output shaft. When the lumpy material in the machine body 1 is continuously crushed by the crushing blades 3 during its drying process, the lumpy material is dispersed into several small pieces. After repeated cycles, it becomes fine particles or powder, so that these materials can be dried more thoroughly in the machine body 1, effectively improving the drying efficiency of the materials.

[0016] 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.
