Description

Technical Field

[0001] This utility model relates to the field of grinding mill technology, and in particular to a cement grinding mill. Background Technology

[0002] Grinding mills are widely used in the grinding and processing of mineral products and cement materials in metallurgy, building materials, chemical industry, mining and other fields. According to the fineness of the cement material being ground and the fineness of the output cement material, grinding mills can be divided into six types: pendulum grinding mill, high-pressure suspension roller grinding mill, high-pressure micro powder grinding mill, straight-through centrifugal grinding mill, high-pressure trapezoidal grinding mill, and three-ring medium-speed grinding mill.

[0003] According to the patent document with authorization announcement number CN220048358U and titled "A Cement Grinding Mill", this new type includes a grinding chamber, a feed inlet, a discharge outlet, an abrasive cone, and a first motor. Two feed inlets are fixedly installed at the top of the grinding chamber, and a discharge outlet is fixedly installed at the bottom. An abrasive cone is installed inside the grinding chamber, and the first motor can drive the abrasive cone to rotate. A screen is installed inside the grinding chamber, and a fixing block is installed at the bottom of the screen. An installation rod is installed inside the grinding chamber, and collision blocks are evenly installed on the outer surface of the installation rod. The collision blocks cooperate with the fixing blocks. In actual use, the screen is designed with an inclined surface, allowing powder that meets the specifications to fall directly to the discharge outlet, while the remaining powder that does not meet the specifications rolls into the recovery chamber. The vibration generated by the cooperation of the fixing blocks and collision blocks not only accelerates the filtration speed but also prevents the screen from being blocked by raw material powder.

[0004] Although the aforementioned cement grinding mill solves the screening problem, non-standard powder rolls into the recovery chamber, making it inconvenient to re-pour the non-standard powder into the grinding chamber for processing, which reduces working efficiency and the functionality of the cement grinding mill.

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] Example 1

[0031] like Figure 1-5As shown, the present invention proposes a cement grinding mill, comprising: a grinding cylinder 1, with a feed inlet 2 at the upper end and a discharge outlet at the lower end; a screening and discharge assembly 3 located on the grinding cylinder 1; and a recycling assembly 5 located on the feed inlet 2 and the screening and discharge assembly 3. The screening and discharge assembly 3 discharges non-standard cement materials into a recycling frame 501, which is moved by a lifting platform 401 to transport non-standard cement materials back to the feed inlet 2 for further grinding.

[0032] Further explanation: The recycling component 5 includes a recycling frame 501 located on the outer wall of the discharge port 301. The recycling frame 501 is equipped with a lifting sleeve 502, which moves up and down via a lifting mechanism 401, which is located inside a protective cover 4. The protective cover 4 is located on the outer wall of the grinding cylinder 1, protecting both the lifting mechanism 401 and the recycling component 5. The recycling frame 501 is equipped with a support frame 503, which is equipped with a second electric telescopic rod 504. The second electric telescopic rod 504 is equipped with a limit seat 505, which is equipped with an installation cover 506. The limit seat 505 moves up and down via the second electric telescopic rod 504, and the movement of the limit seat 505 moves the installation cover 506, which is used to open or close the discharge port of the recycling frame 501. The inclined structure of the recycling frame 501 allows non-standard cement materials to be automatically unloaded into the feed inlet 2. The installation cover 506 is equipped with a guide. By using a lifting sleeve 502 to connect the recycling frame 501 and the elevator 401, the elevator 401 drives the lifting sleeve 502 to move up and down. The lifting sleeve 502 carries the recycling frame 501. When the recycling frame 501 moves up and down, it is connected to the outside of the discharge port 301, so as to collect the cement material that does not meet the standard into it. Then, the elevator 401 moves upward and transports the recycled cement material back into the grinding cylinder 1 through the feed port 2, which can improve the grinding efficiency of cement material and increase the functionality of the cement grinding mill.

[0033] Further explanation: the guide components include guide rods 507 located on both sides of the mounting cover 506, and also include a guide groove 508 located on the recycling frame 501; the guide rods 507 move within the inner wall of the guide groove 508 to assist the mounting cover 506 in moving up and down. The mounting cover 506 controls the opening or closing of the discharge opening of the recycling frame 501, allowing the guide rods 507 on both sides to move within the guide groove 508, facilitating the opening or closing of the mounting cover 506 and increasing the practicality of the recycling assembly 5.

[0034] Example 2

[0035] like Figure 2 and 5As shown, this utility model proposes a cement grinding mill. Based on the above embodiments, this embodiment also details the specific components and their arrangement.

[0036] To further explain, the grinding cylinder 1 is equipped with a motor 101, which is rotatably connected to a rotating shaft 102. The rotating shaft 102 is equipped with crushing blades 103, which rotate via the rotating shaft 102 for crushing cement materials. The grinding cylinder 1 is equipped with a grinding roller 104, which rotates via the rotating shaft 102. A roller mill chamber is provided between the grinding roller 104 and the grinding cylinder 1 for grinding cement materials. The grinding cylinder 1 is equipped with a screening screen 105 for screening the ground cement materials. A motor 101 is installed in the grinding cylinder 1, which drives the rotating shaft 102 to rotate. The rotating shaft 102 rotates the crushing fan blades 103 and the grinding roller 104. The crushing fan blades 103 are used to crush the cement material, and then the grinding roller 104 is used to grind the cement material, which can improve the grinding efficiency of the cement material. At the same time, a screening screen 105 is installed in the grinding cylinder 1. The screening screen 105 is used to screen the cement material after grinding. The cement material that meets the standard is conveyed through the screen holes of the screening screen 105 to the bottom of the grinding cylinder 1 and discharged from the discharge port at the bottom of the grinding cylinder 1.

[0037] To further explain, the screening discharge assembly 3 includes a discharge port 301 located on the outer wall of the grinding cylinder 1. The discharge port 301 has an opening through which a cover plate 302 passes. The cover plate 302 is provided with a push block 303, and the push block 303 is provided with an electric telescopic rod 304. The push block 303 moves up and down via the electric telescopic rod 304, and the push block 303 moves the cover plate 302 to open or close the discharge port 301. Opening it is used to transport non-standard cement material into the recycling frame 501, and closing it is used to stop the transport of non-standard cement material and store the non-standard cement material for a short period of time. It is used in conjunction with the recycling assembly 5 to transport non-standard cement material. One end of the outlet 301 extends through the grinding cylinder 1 and is connected at an inclined angle to the screening screen 105, so that non-standard cement materials are automatically conveyed into the outlet 301. The outlet 301 conveys the cement materials into the recycling frame 501. The recycling frame 501 moves to convey the cement materials into the feed inlet 2. When the recycling frame 501 moves, the outlet 301 is closed by the cover plate 302. Non-standard cement materials are stored in the outlet 301 for a short time. When used in conjunction with the recycling frame 501, it facilitates the use of cement grinding mill structures.

[0038] The working principle of this utility model is as follows: First, cement material is added into the grinding cylinder 1 through the feed inlet 2. The motor 101 is turned on to drive the rotating shaft 102 to rotate. The rotating shaft 102 drives the crushing fan blade 103 and the grinding roller 104 to rotate, so that the cement material is crushed and ground. The ground material flows downward. A screening screen 105 is set at the bottom of the grinding cylinder 1. The screening screen 105 is used to screen the material. The material that meets the standard flows from the screen holes to the discharge port at the bottom of the grinding cylinder 1. The material that does not meet the standard is conveyed to the discharge port 301 through the screening screen 105. The discharge port 301 is connected to the recycling frame 501. The material that does not meet the standard is conveyed to the recycling frame 501. After storing a certain amount of material in the recycling frame 501. Open the electric telescopic rod 304. The electric telescopic rod 304 drives the cover plate 302 to move. The cover plate 302 passes through the opening and closes the discharge port 301, preventing the discharge of non-standard materials. Then, simultaneously open the electric telescopic rod 504. The electric telescopic rod 504 drives the limit seat 505 to move. The limit seat 505, along with the mounting cover 506, closes the discharge port of the recycling frame 501. Then, open the lifting platform 401 and drive the lifting sleeve 502 to move upward. The lifting sleeve 502, along with the recycling frame 501, moves the recycling frame 501 to the feed inlet 2. Again, operate the electric telescopic rod 504 to open the mounting cover 506. Non-standard materials are automatically conveyed into the feed inlet 2, and then the feed inlet 2 conveys the non-standard materials into the grinding cylinder 1 for grinding. Finally, the control elevator 401 moves downward with the lifting sleeve 502, connecting the recycling frame 501 and the discharge port 301, opening its cover plate 302, and conveying non-standard materials into the recycling frame 501. This cyclical operation improves the efficiency of cement grinding.
