Technical Field
[0001] This utility model relates to the technical field of rotary flash dryer accessories, specifically to a novel rotary flash dryer blade. Background Technology
[0002] Rotary flash dryers, as highly efficient and rapid drying equipment, are widely used in many industries such as chemical, pharmaceutical, food, and building materials. Their working principle involves the rapid mixing, dispersion, and drying of hot air and wet materials to achieve a continuous drying process. The blades, as one of the key components of the rotary flash dryer, play a crucial role in the crushing, dispersion, and drying effects of the materials.
[0003] However, most existing traditional rotary flash dryer blade structures on the market currently adopt a design mode of main shaft combined with a single type of blade. This single-structure blade has gradually revealed many problems in practical applications, the most prominent of which is that the blade has little disturbance effect on the material when rotating, which is not conducive to improving the crushing and dispersion of the material.
[0004] Therefore, it is necessary to invent a new type of rotary flash dryer blade to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a novel rotary flash dryer blade to solve the problems mentioned above.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel rotary flash dryer blade, comprising a main shaft, a crushing blade, a disturbance blade, a dispersing mechanism, and a wall scraping mechanism. The crushing blade is fixedly connected to the surface of the main shaft, and multiple sets of crushing blades are arranged in a linear array along the axial direction of the main shaft. Adjacent sets of crushing blades are staggered at 90 degrees. A disturbance blade is provided outside the main shaft. The disturbance blade has a spiral structure and is fixedly connected to each set of crushing blades at corresponding positions. When the disturbance blade rotates with the main shaft, it can agitate the material inside the dryer over a large area.
[0007] Preferably, the disintegration mechanism is located at the top of the main shaft, and the disintegration mechanism includes a first connecting rod, which is inclined and its bottom end is fixedly connected to the top of the main shaft.
[0008] Preferably, the number of the first connecting rods is set to six, and the six first connecting rods are arranged in a circular array. Each of the six first connecting rods is fixedly connected to a dispersing blade for dispersing materials.
[0009] Preferably, the disintegration mechanism further includes a first reinforcing ring, and the six first connecting rods are fixedly connected by the first reinforcing ring.
[0010] Preferably, the wall scraping mechanism is disposed between two sets of the shredding blades. The wall scraping mechanism includes a second connecting rod, one end of which is fixedly connected to the main shaft. The length of the second connecting rod is greater than the length of the shredding blade.
[0011] Preferably, the number of the second connecting rods is set to four, and the four second connecting rods are arranged in a circular array. Each of the four second connecting rods is fixedly connected to a wall scraping blade at its other end.
[0012] Preferably, the scraping mechanism further includes a second reinforcing ring, and the four second connecting rods are fixedly connected by the second reinforcing ring.
[0013] Preferably, one side of the scraper blade is close to the inner wall of the dryer, and the scraper blade can scrape off the material adhering to the inner wall of the dryer when it rotates with the main shaft.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. By setting spiral disturbance blades, which work together with multiple sets of crushing blades distributed at 90 degrees, a large area of disturbance and crushing of materials in the dryer is achieved when the main shaft rotates. This is beneficial to improve the material dispersion effect, solves the problem of insufficient disturbance of materials by traditional blades, and allows hot air to contact the materials more fully, thereby improving drying efficiency. 2. When the main shaft rotates, the dispersing mechanism uses dispersing blades to beat and disperse agglomerated or clustered materials at high frequency, effectively preventing material accumulation and creating favorable conditions for the subsequent drying process. 3. When the main shaft rotates, the scraping mechanism scrapes off the material adhering to the wall surface in a timely manner through the scraping blades, avoiding uneven drying and waste of resources caused by material sticking to the wall.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0018] This utility model provides, for example Figure 1-5 The novel rotary flash dryer blades shown include a main shaft 1, crushing blades 2, agitator blades 3, a dispersing mechanism 4, and a wall scraping mechanism 5. The crushing blades 2 are fixedly connected to the surface of the main shaft 1. Multiple sets of crushing blades 2 are arranged in a linear array along the axial direction of the main shaft 1, with adjacent sets of crushing blades 2 staggered at 90 degrees. Agitator blades 3 with a helical structure are arranged outside the main shaft 1. The agitator blades 3 are fixedly connected to each set of crushing blades 2 at corresponding positions. When the agitator blades 3 rotate with the main shaft 1, they can agitate the material inside the dryer over a large area. Through the synergistic effect of multiple sets of crushing blades 2 arranged at 90 degrees and the helical agitator blades 3, the cutting and crushing ability and large-area agitation effect of the material inside the dryer are significantly enhanced, improving the material dispersion and drying efficiency.
[0019] In one aspect of this embodiment, a dispersing mechanism 4 is disposed at the top of the main shaft 1. The dispersing mechanism 4 includes a first connecting rod 6, which is inclined and whose bottom end is fixedly connected to the top end of the main shaft 1. There are six first connecting rods 6 arranged in a circular array. Each of the six first connecting rods 6 has a dispersing blade 7 fixedly connected to its top end for dispersing materials. The dispersing mechanism 4 also includes a first reinforcing ring 8, which fixes the six first connecting rods 6 together. The dispersing mechanism 4 can perform high-frequency impact and dispersion of agglomerated or clustered materials, effectively preventing material accumulation and optimizing the initial conditions of the drying process. The first reinforcing ring 8 enhances the structural stability of the six first connecting rods 6, avoiding deformation or breakage caused by high-speed rotation, and improving the reliability and service life of the dispersing mechanism 4.
[0020] The wall scraping mechanism 5 is located between two sets of crushing blades 2. The wall scraping mechanism 5 includes a second connecting rod 9, one end of which is fixedly connected to the main shaft 1. The length of the second connecting rod 9 is greater than the length of the crushing blade 2. There are four second connecting rods 9 arranged in a circular array. Each of the other ends of the four second connecting rods 9 is fixedly connected to a wall scraping blade 10. The wall scraping mechanism 5 also includes a second reinforcing ring 11. The four second connecting rods 9 are fixedly connected to each other through the second reinforcing ring 11. One side of the wall scraping blade 10 is close to the inner wall of the dryer. When the wall scraping blade 10 rotates with the main shaft 1, it can scrape off the material adhering to the inner wall of the dryer. The wall scraping mechanism 5, through the second connecting rods 9 which are longer than the crushing blades 2, ensures that the wall scraping blade 10 can be close to the inner wall of the dryer, making it easy to scrape off the material adhering to the wall. The second reinforcing ring 11 enhances the structural integrity of the four second connecting rods 9, avoids deformation or loosening caused by centrifugal force during high-speed rotation, and improves the stability of the wall scraping mechanism 5.
[0021] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-5 When using this utility model, firstly, install the main shaft 1 in the designated position inside the dryer according to the usage requirements, and drive the main shaft 1 to rotate through the drive device inside the dryer; When the material enters the dryer and falls above the dispersing mechanism 4, the main shaft 1 rotates and drives the six ring-shaped array of dispersing blades 7 of the dispersing mechanism 4 to beat and disperse the agglomerated or clustered material at high frequency, preventing the material from accumulating and creating good conditions for the subsequent drying process. When the falling material enters the working area of the crushing blade 2, multiple sets of crushing blades 2 are staggered at 90 degrees along the axis of the main shaft 1. Driven by the rotation of the main shaft 1, the material is cut and crushed in multiple layers to ensure uniform particle size. Meanwhile, the spiral-shaped disturbance blade 3 rotates synchronously with the main shaft 1. Its spiral structure can disturb the material in the dryer over a large area, further enhancing the material dispersion effect. In addition, the four scraping blades 10 of the scraping mechanism 5 rotate close to the inner wall of the dryer under the drive of the main shaft 1, scraping off the material adhering to the wall in time, thus avoiding material sticking to the wall and waste.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
