Description

Technical Field

[0001] This utility model relates to the field of vertical mill technology, specifically to a cement automatic feeding type vertical mill. Background Technology

[0002] Vertical mills are grinding equipment that integrates fine crushing, drying, grinding, powder selection and conveying. They are widely used in the grinding and ultrafine crushing of various solid materials in industries such as cement, building materials, power, metallurgy, chemical industry and non-metallic minerals.

[0003] Although the vertical mills currently in use are equipped with automatic feeding mechanisms, the feeding is not stable, and the amount of material fed may exceed the capacity that the vertical mill can handle, making it difficult to guarantee the yield of high-quality products. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A cement automatic feeding vertical mill includes a feeding mechanism and a fixing mechanism. The feeding mechanism includes a vertical mill body, two support frames located on one side of the vertical mill body, a conveying pipe connected between the two support frames, and a vibrator connected to the top of the conveying pipe. The fixing mechanism includes a vertical plate connected between the two support frames, a cylinder connected to the top of the vertical plate, a lifting rod connected to the movable end of the cylinder, two sealing plates passing through the top and bottom of the conveying pipe, and a connecting rod connecting the lifting rod and the sealing plates.

[0007] By adopting the above technical solution, the raw material is fed from the top of the conveying pipe. During this process, the vibrator accelerates the downward speed of the raw material. At the same time, the cylinder moves the lifting rod up and down. When the sealing plate near the top of the conveying pipe is inserted into the conveying pipe, the sealing plate near the bottom of the conveying pipe opens the inside of the conveying pipe. Then the raw material fills the space between the two sealing plates. Then, when the moving end of the cylinder extends, the sealing plate at the bottom of the conveying pipe is inserted into the inside of the conveying pipe. Then the other sealing plate opens, thereby achieving material fixation. Then the raw material slides into the main body of the vertical mill, accurately controlling the feeding quantity and ensuring the output yield.

[0008] In a preferred embodiment, the present invention may be further configured such that the conveying pipe is inclined and made of stainless steel.

[0009] In a preferred embodiment, the present invention can be further configured such that the vertical mill body and the vibratory machine are connected in series, and the vertical mill body and the cylinder are electrically connected to an external power supply.

[0010] In a preferred embodiment, the present invention can be further configured such that the vertical plate is L-shaped and its bottom is flush with the bottom of the vertical mill body.

[0011] In a preferred embodiment, the present invention can be further configured such that a limiting block is installed on the front side of the upright plate, and the limiting block is slidably sleeved on the outside of the lifting rod.

[0012] In a preferred embodiment, the present invention can be further configured such that: thickened plates are installed at the top and bottom of the conveying pipe, and two sealing plates vertically penetrate the two thickened plates respectively.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, the raw material is fed from the top of the conveying pipe. During this process, the vibrator accelerates the downward speed of the raw material. At the same time, the cylinder moves the lifting rod up and down repeatedly. When the sealing plate near the top of the conveying pipe is inserted into the conveying pipe, the sealing plate near the bottom of the conveying pipe opens the inside of the conveying pipe. Then the raw material fills the space between the two sealing plates. Then, when the moving end of the cylinder extends, the sealing plate at the bottom of the conveying pipe is inserted into the inside of the conveying pipe. Then the other sealing plate opens, thereby achieving material fixation. Then the raw material slides into the main body of the vertical mill, accurately controlling the feeding quantity and ensuring the yield of good products.

[0015] 2. In this utility model, the thickened plate not only strengthens the connection between the sealing plate and the conveying pipe and improves the strength of the conveying pipe, but also guides the sealing plate, making the structure of the device more stable. Attached Figure Description

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an automatic cement feeding vertical mill.

[0027] Example 1:

[0028] Combination Figure 1-3 As shown, the present invention provides a cement automatic feeding vertical mill, including a feeding mechanism 100 and a material fixing mechanism 200. The feeding mechanism 100 includes a vertical mill body 110, two support frames 120 disposed on one side of the vertical mill body 110, a conveying pipe 130 connected between the two support frames 120, and a vibrator 140 connected to the top of the conveying pipe 130.

[0029] The material setting mechanism 200 includes a vertical plate 210 connected between two support frames 120, a cylinder 220 connected to the top of the vertical plate 210, a lifting rod 230 connected to the movable end of the cylinder 220, two sealing plates 240 passing through the top and bottom of the conveying pipe 130 respectively, and a connecting rod 250 connecting the lifting rod 230 and the sealing plates 240.

[0030] Furthermore, the conveying pipe 130 is inclined and made of stainless steel. With this structural design, the raw material entering the conveying pipe 130 can slide down into the interior of the vertical mill body 110 on its own.

[0031] Furthermore, the vertical mill body 110 and the vibrator 140 are connected in series, and the vertical mill body 110 and the cylinder 220 are electrically connected to an external power supply. With this structural design, the device is more convenient to control.

[0032] Furthermore, the vertical plate 210 is L-shaped, and its bottom is flush with the bottom of the vertical mill body 110. This structural design improves the structural stability of the device to a certain extent.

[0033] Example 2:

[0034] Combination Figure 1 and Figure 3As shown, based on Embodiment 1, a limiting block 300 is installed on the front side of the upright plate 210. The limiting block 300 is slidably sleeved on the outside of the lifting rod 230. The limiting block 300 can guide the lifting rod 230, making the lifting rod 230 rise and fall more smoothly.

[0035] Example 3:

[0036] Combination Figure 1 and Figure 3 As shown in the above embodiment, thickened plates 400 are installed at the top and bottom of the conveying pipe 130, and two sealing plates 240 are vertically inserted through the two thickened plates 400 respectively. The thickened plates 400 can reinforce the connection position between the sealing plates 240 and the conveying pipe 130 and improve the strength of the conveying pipe 130.

[0037] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the raw material is fed in from the top of the conveying pipe 130. During this process, the vibrator 140 accelerates the downward speed of the raw material. At the same time, the cylinder 220 moves the lifting rod 230 up and down. When the sealing plate 240 near the top of the conveying pipe 130 is inserted into the conveying pipe 130, the sealing plate 240 near the bottom of the conveying pipe 130 opens the inside of the conveying pipe 130. Then the raw material fills the space between the two sealing plates 240. Then, when the movable end of the cylinder 220 extends, the sealing plate 240 at the bottom of the conveying pipe 130 is inserted into the inside of the conveying pipe 130. Then the other sealing plate 240 opens, thereby achieving material fixation. Then the raw material slides into the vertical mill body 110, accurately controlling the feeding quantity and ensuring the output yield.
