Description

Technical Field

[0001] The utility model relates to the technical field of cement mills, in particular to a grate plate structure capable of reducing energy consumption of cement mills. Background Art

[0002] Cement mill refers to a device used to grind cement powder into finer fineness. It is usually used in the later stages of cement production process, where coarse cement sand and other additives are further ground to obtain the required fineness and quality. Cement mill usually consists of a rotating cylinder with steel balls or other abrasive bodies inside. When cement and other additives enter the cement mill, due to the rotation of the cylinder, the abrasive bodies will collide and rub against the cement particles. This process will break the cement particles and gradually grind them to the required fineness. Cement grinding grate is an important equipment commonly used in cement production process, used for material classification and separation in the grinding system.

[0003] In the process of grinding cement materials by cement mill, the fineness of the materials may be uneven. In order to ensure the coarseness of the materials, the grinding time needs to be increased. The longer the grinding time, the more electric energy will be consumed. Utility Model Content

The utility model has the advantages of being able to adjust the relative distance between grate plate one and grate plate two, grinding cement materials twice in sequence, ensuring the fineness of the materials, and reducing the energy consumption of the cement mill, thus solving the problem that the energy consumption of the cement mill is high in order to ensure the coarseness of the cement materials.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grate plate structure capable of reducing the energy consumption of a cement mill, comprising a grate plate 1, a screw, a fixing sleeve, a grate plate 2 and a screw groove, wherein a fixing plate 1 is welded to the bottom of the grate plate 1, two screws are symmetrically welded to the top of the grate plate 1, the grate plate 1 is provided with a material hole 1 in a circular array, a fixing plate 2 is welded to the top of the grate plate 2, the grate plate 2 is provided with a material hole 2 in a circular array, two bearings are symmetrically installed at the bottom of the grate plate 2, the two inner rings of the two bearings are respectively fixedly installed with fixing sleeves, gripping rods are respectively welded to the two sides of the two fixing sleeves, screw grooves are respectively opened at the bottoms of the two fixing sleeves, and the two screws are respectively meshed and connected with the two screw grooves.

[0006] When using a grate plate structure that can reduce the energy consumption of a cement mill in the technical solution, two sets of gripping rods are used to simultaneously rotate two fixed sleeves, the two fixed sleeves rotate in two bearings, the two fixed sleeves rotate and move on the two screws at the top of the grate plate one through two screw grooves, and the two fixed sleeves drive the grate plate two to move, and adjust the relative distance between the grate plate two and the grate plate one. After the adjustment is completed, the grate plate one is fixed inside the cement mill through the fixing hole one of the fixing plate one, and the grate plate two is fixed inside the cement mill through the fixing hole two of the fixing plate two. The cement material falls onto the grate plate two, and the cement material entering the cement mill is ground by the larger steel balls. After the volume of the material becomes smaller, it passes through the material hole two of the grate plate two and falls onto the grate plate one. The smaller steel balls on the grate plate one grind the cement material for the second time, and the material hole one intercepts the steel balls, and the ground cement material passes through the material hole one.

[0007] Preferably, the fixing plate 1 is provided with fixing holes 1 in an annular array, and the fixing holes 1 penetrate the fixing plate 1. The grate plate 1 is fixed inside the cement mill through the fixing holes 1 of the fixing plate 1 using tools such as bolts.

[0008] Preferably, the fixing plate 2 is provided with fixing holes 2 in an annular array, and the fixing holes 2 penetrate the fixing plate 2. The grate plate 2 is fixed inside the cement mill through the fixing holes 2 of the fixing plate 2 using tools such as bolts.

[0009] Preferably, the two groups of grips are perpendicular to the two fixing sleeves, and anti-slip sleeves are respectively installed on the outer sides of the two groups of grips, which increase the friction between the palm and the grip.

[0010] Preferably, the inner diameter of the material hole 2 is larger than the inner diameter of the material hole 1. Smaller cement materials and steel balls can pass through the material hole 2 and enter the top of the grate plate 1, the material hole 1 intercepts the steel balls, and the ground cement materials pass through the material hole 1.

[0011] Preferably, the outer diameter of the grate plate 1 is the same as the outer diameter of the grate plate 2, and the grate plate 1 is parallel to the grate plate 2. There will be no deviation between the grate plate 1 and the grate plate 2 during installation.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model is provided with a screw rod, a fixing sleeve, a grate plate one and a grate plate two, and two groups of gripping rods are used to rotate the two fixing sleeves at the same time. The two fixing sleeves rotate in two bearings, and the two fixing sleeves rotate and move on the two screw rods at the top of the grate plate one through two screw grooves. The two fixing sleeves drive the grate plate two to move, and the relative distance between the grate plate two and the grate plate one is adjusted, and the grate plate one and the grate plate two are fixed inside the cement mill, and the cement material falls onto the grate plate two, and the cement material entering the cement mill is ground by the larger steel ball. After the volume of the material becomes smaller, it passes through the material hole two of the grate plate two and falls onto the grate plate one, and the smaller steel ball on the grate plate one grinds the cement material for the second time, and the material hole one intercepts the steel ball, and the ground cement material passes through the material hole one, so that the relative distance between the grate plate one and the grate plate two can be adjusted, and the cement material is ground twice in sequence, so as to ensure the fineness of the material and reduce the energy consumption of the cement mill.
