Description

Technical Field

[0001] The utility model relates to the technical field of vertical mill scraping, in particular to a vertical mill scraping mechanism. Background Art

[0002] Vertical mill is a grinding equipment integrating fine crushing, drying, grinding, powder selection and conveying. It is widely used in grinding and ultra-fine grinding of various solid materials in cement, building materials, electric power, metallurgy, chemical industry, non-metallic minerals and other industries. When the current vertical mill is unloading, the material is easy to accumulate in the middle of the grinding disc and is difficult to be evenly dispersed. In addition, there are inevitably larger materials in the accumulated materials, and it is difficult for the grinding roller to quickly grind the larger materials, which makes the grinding efficiency of the grinding roller low. The accuracy of the ground materials varies, which is not conducive to subsequent processing. In addition, the ground materials are easy to stick to the grinding disc and cannot be discharged quickly, which is not conducive to subsequent processing. Therefore, a scraping mechanism for a vertical mill is proposed. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0025] A vertical mill scraper mechanism provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0026] Embodiment 1:

[0027] Combination Figure 1-6 As shown, the utility model provides a vertical mill scraper mechanism, including a body structure 100, an abrasive structure 200, a cutting structure 300 and a scraper structure 400, the body structure 100 includes a shell 110, a discharge cylinder fixedly installed at the upper end of the shell 110, a feed cylinder 130 and a support seat 140 fixedly installed on the outer side of the shell 110 from top to bottom, and a discharge device 150 fixedly installed at the bottom of the shell 110, the abrasive structure 200 includes a filter device 210 and a grinding disc 230 fixedly installed in the inner cavity of the shell 110 from top to bottom, a transmission arm 220 fixedly installed at the upper end of the support seat 140, and a grinding roller (240) fixedly installed at the output end of the transmission arm 220, a vertical mill scraper mechanism, characterized in that a fixing rod 250 is fixedly installed on one side of the grinding roller 240, the cutting structure 300 includes a cylinder 310 fixed at the bottom end of the filter device 210, a feeding cylinder 130 and a supporting seat 140 fixedly installed on the outer side of the shell 110 from top to bottom, and a feeding cylinder 150 fixedly installed at the bottom of the shell 110. 10, a support rod 320 on the outside, a telescopic rod 330 movably mounted in the inner cavity of the cylinder 310, a blade 350 fixed at the bottom end of the telescopic rod 330, the bottom of the blade 350 is designed to be arc-shaped, and the blade 350 does not contact the grinding disc 230, a lever 360 fixedly sleeved on the outside of the telescopic rod 330, and a notch 340 is provided on the outside of the cylinder 310 to fit the lever 360. The interior of the cylinder 310 is designed to be hollow, and the telescopic rod 330 is movably sleeved. The outer spring 370 and the connecting block 380 fixed on one side of the blade 350, the scraper structure 400 includes a movable plate 410 movably sleeved on one end of the support rod 320, a scraper 420 fixed at the bottom end of the movable plate 410, the length of the scraper 420 is shortened from left to right, and the scraper will not conflict with the grinding disc 230, and a connecting rod 430 movably sleeved on both sides of the bottom end of the scraper 420, and the connecting rod 430 is movably sleeved on the inner side of the connecting block 380.

[0028] Specifically, when the fixed rod 250 rotates with the grinding roller 240, the fixed rod 250 will not conflict with the grinding disc 230, thereby preventing the grinding disc 230 from being worn due to the friction between the fixed rod 250 and the fixed rod 250. In addition, the fixed rod 250 conflicts with the lever 360 when rotating. Through the rotation of the fixed rod 250, the lever 360 is pressed downward, so that the blade 350 fixed under the telescopic rod 330 cuts the material into pieces. When larger materials gather around the grinding roller 240, the blade 350 cuts all the gathered larger materials into pieces, so that the materials are no longer blocked around the grinding roller 240, which makes it convenient for the grinding roller 240 to quickly grind the materials, thereby increasing the grinding efficiency and improving the practicability of the equipment.

[0029] Embodiment 2:

[0030] Combination Figure 4 and Figure 5 As shown, based on the first embodiment, a notch 340 is provided on the outer side of the cylinder 310 to fit the lever 360 , the interior of the cylinder 310 is hollow, the bottom of the blade 350 is arc-shaped, and the blade 350 does not contact the grinding disc 230 .

[0031] Specifically, a rectangular notch 340 is provided on the outer wall of the cylinder 310, and the width of the notch 340 matches the lever 340. The notch 340 is used to limit the up and down movement of the lever 360. The lever 360 is pressed to the upper end of the notch 340 by the spring 370. When the lever 360 is released from the pressure of the fixed rod 250, the telescopic rod 330 is quickly reset by the spring 340. Since the shape of the grinding disc 230 is concave inward, the bottom of the blade 350 is designed to be arc-shaped. Therefore, the blade 350 will not cut the grinding disc 230 when cutting the material, thereby avoiding damage caused by the blade 350 cutting the grinding disc 230. Through repeated cutting by the blade 350, larger materials are directly crushed so that the grinding roller 240 can grind them directly, thereby avoiding insufficient grinding due to excessively large materials and uneven precision of the finished products after grinding, thereby improving the reliability of the device.

[0032] Embodiment three:

[0033] Combination Figure 4-6 As shown, in the above embodiment, the connecting rod 430 is movably sleeved on the inner side of the connecting block 380 , and the length of the scraper 420 is shortened from left to right, so that the scraper will not conflict with the grinding disc 230 .

[0034] Specifically, when the blade 350 moves downward, the end of the connecting rod 430 that is sleeved on the connecting block 380 also moves downward, so the connecting rod 430 pushes the movable plate 410 forward, and the movable plate 410 starts to rotate with one end of the support rod 320 as the axis point, so that the scraper 420 fixed under the movable plate 410 also starts to rotate, and then the scraper 420 is in a downward vertical state, and the bottom ends of multiple scrapers 420 are close to the grinding disc 230. When the blade 350 is reset, the connecting rod 430 pulls the movable plate 410 to reset the scraper 420. When the grinding disc 230 rotates, the accumulated material is evenly scraped away by the scraper 420 to keep the thickness of the material nearly consistent. At the same time, the scraper 420 can also scrape the material attached to the grinding disc 230 to avoid the material sticking together, facilitate the material to be discharged to the outside, and improve the effectiveness of the equipment.

[0035] The working principle and use process of the utility model are as follows: first, the equipment is debugged, the discharge barrel 120 is connected to the discharge pipe, and the feed barrel 130 is connected to the feed pipe. After the debugging is completed, the material is discharged onto the grinding disc 230 through the feed barrel 130, and then the grinding disc 230 starts to rotate, and at the same time, the grinding roller 250 starts to rotate to grind the material. When the grinding roller 250 rotates, the fixed rod 250 presses the lever 360, so that the blade 350 cuts the larger material into pieces, and at the same time, the scraper 420 scrapes the accumulated material and scrapes the material adhered to the grinding disc 250. The ground material is moved to the edge by the grinding disc 250, and the ground material is blown out to the top of the inner cavity of the shell 110 through the discharge device 150. The unqualified material is discharged onto the grinding disc 230 again through the filtering device 210, and the remaining material enters the discharge pipe through the discharge barrel 120 to obtain qualified material.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
