Description

Technical Field

[0001] The invention belongs to the technical field of cement production equipment, and in particular relates to ultrafine grinding equipment and a grinding process thereof for cement production. Background Art

[0002] Cement is a powdery, hydraulic inorganic gelling material. It forms a slurry after being stirred with water. It can harden in air or water, and can firmly bind materials such as sand and stone together. 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 and national defense projects as an important gelling material. The coarseness of cement will directly affect the strength and durability of concrete. In order to improve the accuracy of cement use, ultrafine grinding equipment is required to grind it during the cement production process.

[0003] For example, in a Chinese patent document (CN112619803B), a grinding device for cement clinker production is described, in which a second bearing seat and a first bearing seat are symmetrically fixed at both sides above the base, a ball milling part is provided between the second bearing seat and the first bearing seat, and a pretreatment part connected to the ball milling part is provided on the outside of the second bearing seat. The invention has a novel design and a simple structure. The pretreatment part can be used to screen and cool the newly entered clinker, which can ensure the particle size of the clinker on the one hand and reduce the surface temperature of the clinker on the other hand to avoid excessive temperature or large particle size difference. To solve the problem of poor quality of cement, the cleaning mechanism can clean the holes on the surface of the filter plate without manual cleaning, which reduces maintenance costs, solves the problem of filter plate blockage affecting the powder pass rate, and effectively improves work efficiency. However, during the use of this equipment, the centrifugal force of the ball mill itself often swings the grinding steel balls inside it to a high place, and then the impact force of the balls during the falling process is used to grind the cement. At this time, the grinding efficiency will be affected by the gravity of the grinding balls themselves, resulting in the collision effect between them, which in turn affects the overall grinding efficiency and grinding effect of the cement. Therefore, certain improvements are needed. Summary of the Invention

[0024] An ultrafine grinding process for cement production comprises the following steps:

[0025] S1. First, place the equipment in a suitable place and connect the feed port to the external feed device. The external feed device transports the cement raw materials to be ground and several steel balls to the inside of the cylinder and the inner lining plate through the feed port.

[0026] S2. The connecting shaft, the second gear, the annular outer gear, the cylinder, the inner lining plate, the cement raw materials therein, and the plurality of steel balls are driven by a driving motor to rotate, so that the plurality of steel balls therein grind the cement raw materials;

[0027] S3. The cement raw materials and the plurality of steel balls inside the cylinder body will enter between the arc-shaped baffle and the plurality of connecting blocks under the centrifugal action. At this time, the cylinder body will drive the annular internal gear to rotate, so that the first gear drives the first rotating shaft and the plurality of connecting blocks to rotate rapidly.

Under the action of the first protrusion, the first roller drives the first roller, the fixed rod and the conical block to move upward, so that the second roller, the connecting rod, the ball joint support and the crushing block move outward, and the cement raw materials entering the screen frame are auxiliary crushed by the crushing block;

[0029] S5.

[0030] S6. At the same time, the annular internal gear will drive the second protrusion to rotate, causing the third roller to drive the guide rod, vertical plate, horizontal plate and conical protrusion to move horizontally, and then the conical protrusion will drive the round rod, connecting plate, rectangular block and knocking block to move, and the knocking block will knock and vibrate the surface of the inner lining plate to assist in cleaning it.

[0031] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0032] 1. In the present invention, by providing a speed regulating component, the cement raw materials and several steel balls inside the cylinder will enter between the arc-shaped baffle and the multiple connecting blocks under the centrifugal action, and at this time the cylinder will drive the annular internal gear and the first gear to rotate. Since the diameter of the annular internal gear is larger than the diameter of the first gear, the rotation speed of the first gear is greater than the rotation speed of the annular internal gear. Therefore, the first gear will drive the first rotating shaft and the multiple connecting blocks to rotate rapidly, and the multiple connecting blocks will cooperate with the force of the arc-shaped baffle to rotate the cement raw materials and several steel balls inside them during the rotation process, so as to help improve the overall speed and force of the steel balls in the falling process, thereby improving the space between the multiple steel balls. The first rotating shaft and the plurality of connecting blocks continuously rotate, and when the first rotating shaft and the plurality of connecting blocks rotate to the end of the arc-shaped baffle, the first spring drives the sliding plate, the sliding block and the cleaning block to gradually move outward, and contact the surfaces of the plurality of steel balls that gradually move out of the arc-shaped baffle and the plurality of connecting blocks to assist in cleaning the surfaces thereof, so as to prevent the cement raw materials from adhering to the surfaces of the plurality of steel balls and improve their quality, thereby reducing the falling speed of the steel balls and preventing the collision effect between the plurality of steel balls from being affected, thereby preventing the grinding quality of the equipment from being affected.

[0033] 2. In the present invention, through the auxiliary grinding assembly set up, the cement raw materials between multiple connecting blocks will enter the interior of the screen frame through the screen frame. At this time, the first rotating shaft will drive the first roller to move on the circular shaft and the first protrusion. Under the action of the first protrusion, the first roller drives the first roller, the fixed rod and the conical block to move upward, so that the second roller drives the connecting rod, the ball joint support and the crushing block to move outward, and the cement raw materials entering the screen frame are auxiliary crushed by the crushing block, so as to improve the subsequent steel ball grinding effect and grinding efficiency of the cement raw materials, and further improve the equipment's grinding effect on cement.

[0034] 3. In the present invention, through the auxiliary cleaning component, the annular internal gear will drive the second protrusion to rotate, and through the second protrusion, the third roller will drive the guide rod, vertical plate, horizontal plate and conical protrusion to move horizontally, so that the round rod will drive the connecting plate, rectangular block and knocking block to move, and the knocking block will knock and vibrate the surface of the inner lining plate to discharge the cement raw materials between the multiple inner lining plates, so as to prevent it from adhering to the multiple inner lining plates after a long time, which will affect the service life of the inner lining plates, and prevent it from affecting the grinding and discharging effect of the cement raw materials.
