Description

Technical Field

[0001] The utility model relates to the technical field of cement vertical mills, in particular to a raw material fineness control component. Background Art

[0002] Vertical mills are widely used in industrial production. Vertical mills generally include an electric mill composed of a grinding roller and a grinding disc. Above the electric mill is a separator, also known as a powder concentrator, which separates the powder processed by the electric mill. Figure 1 As shown, the separator consists of two parts, namely a fixed outer separation cylinder and an inner separation cylinder that rotates relative to the outer separation cylinder. The outer separation cylinder is a squirrel cage type, which is composed of a number of static blades fixed between two rings. When the raw material is too fine, the surface area of ​​the particles will be reduced, which will lead to contact between the particles during the calcination process. At the same time, the surface area of ​​the particles is small, the free energy is reduced, and it is not easy to participate in the reaction, resulting in incomplete decomposition of calcium carbonate in the raw material, which is easy to cause an increase in free calcium oxide, a decrease in clinker quality, and a decrease in clinker strength. Therefore, there is a certain angle between the static blades and the dynamic blades to improve the particle size of the raw material.

[0003] Chinese utility model patent: Publication number CN201055848Y discloses a vertical wear-resistant ceramic static blade, which includes a lining plate and a wear-resistant layer fixed on the lining plate. The static blade is divided into several sections, which are connected by a connecting mechanism to form a whole. The wear-resistant layer is wear-resistant ceramic.

[0004] In the existing technology CN201055848Y, the static blades are divided into several sections during use, so the installation is greatly convenient; and since the prices of chrome corundum and white corundum are cheap, the use cost is greatly reduced; since the hardness of chrome corundum and white corundum is much greater than that of wear-resistant steel, the service life is longer.

[0005] However, the blades used in the prior art have a large contact area with the raw material when participating in the vertical mill operation, and thus may break due to poor toughness under the impact of the raw material, thus affecting the use. Therefore, a raw material fineness control component is needed to solve the above problem. Utility Model Content

[0006] The utility model aims to provide a raw material fineness control component, which has the advantage of reducing the contact area with the raw material to avoid breakage, and solves the problem that the blades of the device in the prior art are prone to breakage when in use.

[0007] To achieve the above object, the utility model provides the following technical solution: a raw material fineness control component, comprising a mounting frame, wherein the mounting frames are two in number, and a blade frame body is fixedly mounted on opposite sides of the two mounting frames in a circular array, and further comprising a blade body;

[0008] The blade body is fixedly installed on the inner side of the blade frame body.

[0009] When using a raw material fineness control component in the technical solution, the blade frame body is welded and installed on the opposite sides of two mounting frames, and the blade body is inserted into the inner side of the blade frame body. At the same time, the blade body inserted into the inner side of the blade frame body is positioned by installing bolts, and one end of the blade body passes through the blade frame body. The blade body extending out of the blade frame body serves as a stationary blade that contacts the raw material. When participating in the raw material vertical mill operation as a stationary blade, the contact area between the blade body and the raw material can be reduced, and under the clamping action of the blade frame, the blade body can be prevented from being broken due to excessive impact.

[0010] Preferably, the two mounting frames are both designed with an annular structure, and the two mounting frames are both provided with first mounting holes in an annular array.

[0011] By adopting an annular structure design for both mounting frames and opening first mounting holes in an annular array on both mounting frames, the two mounting frames can be installed through the first mounting holes, so that the control component is installed in the sealing mechanism of the vertical mill and used as a stationary blade.

[0012] Preferably, second mounting holes are provided at both upper and lower ends of the side surface of the blade frame body, and a through mounting groove is provided at the front surface of the blade frame body.

[0013] By opening second mounting holes at both upper and lower ends of the side of the blade frame body and opening a through mounting groove on the front of the blade frame body, mounting bolts can be inserted through the second mounting holes, and the blade body can be clamped and installed through the through mounting groove, thereby achieving positioning of the blade body.

[0014] Preferably, the longitudinal cross-sectional dimension of the mounting groove matches the longitudinal cross-sectional dimension of the blade body.

[0015] By matching the longitudinal cross-sectional dimension of the installation groove with the longitudinal cross-sectional dimension of the blade body, the blade body can be inserted into the installation groove in a seamless manner, thereby achieving the purpose of positioning and clamping the blade body through the blade frame body.

[0016] Preferably, a mounting bolt is movably inserted into the second mounting hole.

[0017] A mounting bolt is movably inserted into the second mounting hole, so that the blade body can be positioned and mounted by the mounting bolt.

[0018] Preferably, a limiting groove is provided at the rear end of the side surface of the blade body, and the hardness of the blade body is greater than the hardness of the blade frame body.

[0019] By providing a limiting groove at the rear end of the side surface of the blade body, the blade body can be clamped after the mounting bolt passes through the limiting groove.

[0020] Preferably, the mounting bolt passes through the limiting groove, and the blade body is fixedly mounted on the inner side of the blade frame body by the mounting bolt.

[0021] By passing the mounting bolts through the limiting grooves, the blade body is fixedly mounted on the inner side of the blade frame body through the mounting bolts, thereby achieving fixed installation of the blade body. After fixed installation, one end of the blade body passes through the blade frame body to participate in the vertical mill operation of raw materials.

[0022] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0023] The utility model sets a blade frame body and fixes the blade body on the inside of the blade frame body. During specific operation, the blade frame body is welded and installed on the opposite sides of two mounting frames, and the blade body is inserted into the inside of the blade frame body. At the same time, the blade body inserted into the inside of the blade frame body is positioned by installing bolts, and one end of the blade body passes through the blade frame body, and the blade body extending out of the blade frame body serves as a stationary blade that contacts the raw material. When participating in the operation of the raw material vertical mill as a stationary blade, the contact area between the blade body and the raw material can be reduced, and under the clamping action of the blade frame, the blade body can be prevented from being broken due to excessive impact, thereby achieving the effect of reducing the contact area with the raw material and avoiding breakage.
