Description

Technical Field

[0001] The utility model relates to the technical field of cement production equipment, in particular to a cement grinding device. Background Art

[0002] Cement is a powdery, hydraulic, inorganic cementitious material. Cement becomes a slurry after being mixed with water. It can harden in the air or in water, and can firmly bond materials such as sand and stone together. The early mixture of lime and volcanic ash is very similar to modern lime volcanic ash cement. It is used to bond concrete made of crushed stone. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been widely used in civil engineering, water conservancy, national defense and other projects as an important cementitious material. In the grinding process, cement will be applied to the ball mill to further grind the crushed raw materials.

[0003] Chinese utility model patent: Publication number CN215197334U, discloses a technical field related to cement production equipment, specifically a cement grinding device, including a mill cylinder, a feed port, a discharge port, and a driving device. A mill liner is fixedly installed on the inner wall of the mill cylinder, and the mill liner is composed of multiple liner plates spliced ​​together. The liner plate is composed of a liner base and a hard alloy plate. A noise reduction groove is opened on the plate body of the liner base, and the noise reduction groove is filled with sound-absorbing rubber.

[0004] In the prior art, CN215197334U, when in use, effectively reduces the noise impact of the ball mill during operation through the sound-absorbing effect of the sound-absorbing rubber in the noise-reducing groove on the lining substrate; by opening a noise-reducing groove on the plate body of the lining substrate and filling the noise-reducing groove with sound-absorbing rubber, the noise impact of the ball mill during operation is reduced through the sound-absorbing effect of the sound-absorbing rubber, thereby reducing the impact of noise on operators and the surrounding environment. However, during the grinding process, due to long-term contact with the raw materials, the temperature of the lining plate rises rapidly due to friction. The prior art does not have the function of cooling the lining plate, which results in the lining plate being too hot during use, thereby affecting its service life. Therefore, a cement grinding device is needed to solve the above problem. Utility Model Content

[0007] The connecting grooves are arranged on both sides of the inner wall of the mill barrel body; wherein, holes are opened in both connecting grooves at equal distances and the first connecting pipes are embedded and installed.

[0008] When using a cement grinding device in the technical solution, the adjacent inner sleeve bodies at the front and rear ends are plugged in, and the bolts are driven through the mounting holes to fix the inner sleeve body on the inside of the mill barrel body. When in use, the mill barrel body is protected by the inner sleeve body, and cold air is injected into the first connecting pipe through the second connecting pipe, and the cold air is injected into the connecting groove. At the same time, the reserved groove is connected to the connecting groove, so that the inner sleeve body can be cooled by cold air.

[0009] Preferably, a second connecting pipe is fixedly installed on the outside of the mill barrel body, and the second connecting pipe is connected to the first connecting pipe.

[0010] Preferably, mounting holes are provided at both the front and rear ends of the inner wall of the inner sleeve body, and reserved grooves are provided at equal intervals on the outer wall of the inner sleeve body.

[0011] Preferably, bolts pass through the mounting holes, and the front and rear ends of adjacent inner bushing bodies are plugged into each other and fixedly connected to the mill barrel body by bolts.

[0012] Preferably, the connecting groove is connected to the reserved groove and installed, and the depth of the connecting groove is one third of the thickness of the mill barrel body.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model sets a mill barrel body, sets a connecting groove on the inner wall of the mill barrel body, embeds and installs a first connecting pipe in the connecting groove, sets a reserved groove on the outer wall of the inner liner body, and connects the reserved groove with the connecting groove, so that the cold air injected through the first connecting groove can enter the reserved groove through the connecting groove, and then cool the inner liner body, thereby improving the equipment in the prior art, so that it has the function of cooling, and thus has the effect of extending the service life.
