[0002] The pulverizer blade is easy to appear the problem that the rotating resistance of the blade is big and the pulverizing efficiency is reduced when carrying out the pulverizing operation to the sticky material.
[0003] The reason causing this phenomenon is that the material with big viscosity is easy to stick to the blade in the pulverizing process, and the sticking increases the load of the blade, so that the rotating resistance of the blade is increased, and the pulverizing efficiency is reduced.
[0004] In view of the above, we propose a circular knife type pulverizer blade to solve the above problems. UTILITY MODEL CONTENTS

[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] (1) The circular knife type pulverizer blade of the utility model reduces the sticking of the material by virtue of the extremely low surface energy of the Teflon hydrophobic coating, so that the material is difficult to form firm adhesion on the surface of the Teflon hydrophobic coating.
[0012] (2) The trapezoidal abrasive plate of the circular knife type pulverizer blade of the utility model reduces the contact area with the material by the micro-protruding structure of the trapezoidal abrasive plate, realizes the anti-sticking effect, and the rough surface of the abrasive plate destroys the ability of the material to continuously adhere, so that the anti-sticking effect is further improved.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0020] Please refer to Figures 1-4 A circular knife type pulverizer blade, comprising a blade body 1 and blade teeth 11 distributed on the side surface of the blade body 1, an inclined hydrophobic coating 12 is arranged at the connecting position of the blade body 1 and the blade teeth 11, a clamping groove 2 is arranged on the upper and lower surfaces of the blade body 1, a clasp 3 is detachably connected to the inside of the clamping groove 2 in a magnetic manner, a plurality of sanding plates 31 are fixedly connected to the upper end of the clasp 3, the sanding plates 31 are arranged in a trapezoidal shape, the front and rear ends of the sanding plates 31 are arranged in a large inclination, and the two sides are slightly inclined, when in use, the clasp 3 is flush with the blade body 1 after installation, the sanding plates 31 on the upper end are slightly convex, and the sanding plates 31 are slightly higher than the blade body 1, the plurality of slightly convex sanding plates 31 can effectively reduce the contact area between the viscous material and the blade body 1, so that the blade body 1 has a certain anti-sticking effect through the sanding plates 31, meanwhile, the surface of the sanding plates 31 is rough and uneven, which can further increase the anti-sticking effect, thereby greatly reducing the material sticking, reducing the rotating resistance and improving the pulverizing effect.
[0021] Further, the hydrophobic coating 12 is coated on the surface of the connection between the blade body 1 and the blade teeth 11, which is used to reduce the adhesion of the material. In use, the hydrophobic coating 12 is a Teflon PTFE hydrophobic layer. The surface energy of Teflon is extremely low, about 18-20 mN / m, which makes it have excellent hydrophobic and oleophobic properties. When it is coated on the surface of the blade, it is difficult for viscous materials to form a firm adhesion on its surface, and it has certain high temperature resistance. Therefore, when the crushing surface temperature of the blade increases, the hydrophobic coating 12 will not lose the anti-adhesion effect, thereby increasing the crushing efficiency.
[0022] Further, the center of the blade body 1 is provided with a through mounting hole 13. In use, the mounting hole 13 can facilitate the connection of the blade body with the rotating shaft, thereby facilitating the subsequent crushing work.
[0023] Further, the bottom surface of the clamping groove 2 is provided with a first magnetic surface 21, and the connecting surface of the clamping ring 3 and the clamping groove 2 is provided with a second magnetic surface 32. The first magnetic surface 21 and the second magnetic surface 32 are magnetically connected. In use, the first magnetic surface 21 and the second magnetic surface 32 are strongly magnetically connected. When the sanding plate 31 is used for a long time, its surface is gradually ground flat, and the anti-adhesion effect is poor. Therefore, the worker can pry up the clamping ring 3 to replace the sanding plate 31, thereby increasing the overall applicability.
[0024] Working principle: the circular knife type pulverizer blade of the utility model, in use, the blade body 1 is installed on the rotating shaft through the mounting hole 13 and starts to rotate. The blade teeth 11 distributed on the side of the mounting hole 13 cut and crush the material. The hydrophobic coating 12 relies on the inclination and extremely low surface energy to make it difficult for viscous materials to form a firm adhesion on the surface of the blade body 1, thereby reducing the adhesion. At the same time, the micro convex of the trapezoidal sanding plate 31 reduces the contact area of the blade body 1 with the material. The rough surface of the trapezoidal sanding plate 31 destroys the ability of the material to continuously adhere, which can further improve the anti-adhesion effect of the blade body 1. When the surface of the sanding plate 31 is gradually ground flat, the clamping ring 3 can be prised up to facilitate replacement, thereby increasing the overall applicability.
