Problems solved by technology

However, there are the following problems. One is that the multi-layer structure causes the entire blade structure to be thicker and more complex, which makes the friction between the material and the material during the rotation process greater, resulting in greater force on the blade and the plum blossom frame. It is easy to be damaged; the second is that in the multi-layer structure, due to the upper bottom plate, the materials in the gaps are not easy to be thrown out, and the materials thrown out may also be too concentrated (come out of one mouth), and some materials are too concentrated.

Embodiment 1

[0028] Please refer to figure 1 and figure 2 , this preferred embodiment provides a blade for Raymond machines, including a blade panel 10 and a blade side plate 20 arranged on one edge of the blade panel 10, the blade panel 10 has a feed end 11 and At the discharge end 12 , the shovel panel 10 is arc-shaped, and the direction of protrusion is toward the bottom surface of the shovel panel 10 .

[0029] The traditional shovel blade has a straight structure on the blade panel, so after the material exits the discharge end of the blade panel, a relatively straight and horizontal material flow is formed. This type of material flow is basically in a On the horizontal surface (when entering between the grinding roller and the grinding ring), it is too concentrated, so the grinding effect is not good, the efficiency is not high, and it will even affect the grinding roller and the grinding ring, and accelerate the damage of the grinding roller and the grinding ring. In the present ...

Embodiment 2

[0031] Please refer to image 3 , different from Embodiment 1, in this preferred embodiment, the width of the blade panel 10 at the end having the feed end 11 is greater than the width of the blade panel 10 at the end having the discharge end 12 . The width of the shovel panel 10 at the end with the feed end 11 is greater than the width of the shovel panel 10 at the end with the discharge end 12, on the one hand it is more conducive to feeding, on the other hand it can also make the thrown material form a cone The shape is closer to the angle formed by the grinding roller and the grinding ring when the Raymond machine is running, so that the dispersion effect is better, and it is more evenly dispersed between the grinding roller and the grinding ring to achieve better grinding effect and efficiency.

Embodiment 3

[0033] Please refer to Figure 4 , different from Embodiment 2, in this preferred embodiment, the shovel panel 10 is provided with a plurality of strip-shaped material guide protrusions 13 near the discharge end 12, and a plurality of material guide protrusions 13 are formed between A plurality of material guide grooves 14 , the outlets of the material guide grooves 14 are facing the discharge end 12 of the blade panel 10 . A plurality of material guide protrusions 13 form a plurality of material guide grooves 14, and materials go out from the plurality of material guide grooves 14 to form a plurality of throwing material flows, so that the material throwing is more uniform and dispersed. The material guide protrusion 13 is arc-shaped, and the entrance of the material guide groove 14 formed by a plurality of material guide protrusions 13 faces the feed end 11 of the blade panel 10 to ensure that the material can enter from the feed end 11 smoothly and at high speed. Feed chut...

Abstract

The invention relates to the technical field of powder grinding machining, and discloses a scraper knife for a Raymond mill. The scraper knife mainly aims at solving the problem that materials are centralized excessively when scattered by an existing scraper knife. The scraper knife for the Raymond mill comprises a scraper knife panel and a scraper knife side plate arranged on the edge of one sideof the scraper knife panel. A feed end and a discharge end are arranged on the scraper knife panel, the scraper knife panel is in an arc shape, and the arc protrudes towards the bottom face of the scraper knife panel. As the scraper knife panel is in the arc shape, when the materials go out of the discharge end of the scraper knife panel, the more inclined upcast effect is achieved, thus, material flow with the more obvious upcast effect can be formed by the scattered materials, and then the materials are scattered more uniformly and dispersively. According to the scraper knife for the Raymond mill, the material scattering effect is good, compared with a traditional scraper knife, the materials are scattered more uniformly and dispersively, and therefore the forming effect is better and the efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of grinding processing, in particular to a shovel blade for a Raymond machine. Background technique [0002] Raymond machine is the main equipment for powder production. It is often used to process barite, calcite, potassium feldspar, talc, marble, limestone, etc. into a certain number of powders. [0003] The main machine of the Raymond machine mainly includes a plum blossom frame, a grinding roller set on the plum blossom frame and a grinding ring matched with the grinding roller. The rotation of the plum blossom frame drives the grinding roller to do the revolution around the plum blossom frame and the self-rotation of its own rotation. During the revolution, there is a centrifugal effect, which makes the grinding roller press the grinding ring, so that the material between the grinding roller and the grinding ring is ground into powder until it reaches the required level. mesh number. There is also a s...
