Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding equipment technology, and in particular to an environmentally friendly cement grinding equipment. Background Technology
[0002] Cement is an important inorganic cementitious material made from raw materials such as limestone and clay through high-temperature calcination and grinding. When mixed with water, it can harden into a solid stone-like substance and is widely used in construction, roads, bridges and other fields.
[0003] Cement grinding equipment is the core equipment in cement production. It mainly consists of mills, classifiers, and blowers. After being crushed, the raw materials enter the mill and are pulverized into fine powder by the grinding action of steel balls or steel segments. Modern cement grinding equipment is also equipped with high-efficiency and energy-saving motors to reduce energy consumption and improve production efficiency and environmental performance.
[0004] In existing cement grinding devices, irregularly shaped liners are typically installed inside to enhance the collision and shearing effects during the grinding process, thereby improving grinding efficiency. However, the liner plates currently used have significant shortcomings, as their shape design is relatively simple and lacks diversity. This single shape cannot adequately adapt to the complex movement of cement within the grinding chamber, failing to effectively grind the cement from all directions and angles, ultimately resulting in the overall grinding efficiency falling short of the ideal level. Based on this, this utility model is proposed. Utility Model Content

[0009] Furthermore, the first support plate and the guide support plate are provided with grinding protrusions. When the grinding ball rolls on the first support plate and the guide support plate, the grinding ball crushes the fine particles.
[0010] Furthermore, the first support plate and the guide support plate are provided with guide ramps that slope to both sides. The guide ramps are used to guide large pieces of cement to slide to the boss liner and the ball-holding plate for crushing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] Example 1: Refer to Figures 1-5 An environmentally friendly cement grinding device includes a support base 1 and a barrel 2. The barrel 2 is rotatably connected to the support base 1. The device also includes: a rolling support assembly 3, a boss liner 4, and a ball-holding plate 5 arranged in an equidistant circular array around the axis of the barrel 2 on the inner wall of the barrel 2; grinding balls of different sizes are installed inside the barrel 2. When the barrel 2 rotates, the ball-holding plate 5 causes the grinding balls to fall from a higher position; the rolling support assembly 3 is symmetrically arranged on both sides of the ball-holding plate 5. When the barrel 2 rotates, some of the grinding balls are guided into the ball-holding plate 5 by the rolling support assembly 3.
[0028] In this utility model, compared with the traditional single-shaped liner, this device is provided with three types of raised liner on the inner wall of the barrel 2: rolling support component 3, boss liner 4, and ball-holding plate 5. In this way, the advantages of different shapes can be combined to play the best role, achieve synergistic effect, and thus improve grinding efficiency.
[0029] like Figure 4 As shown, the upper part of the unfolded barrel 2 is the direction of rotation. The boss liner 4 is a common liner shape that can drive some grinding balls to rise to the normal height and be thrown out through the upper inclined surface, thereby crushing and grinding the cement below. By adding the ball-holding plate 5, this device can drive some grinding balls to fall from a higher position, thereby converting more gravitational potential energy into kinetic energy and improving the crushing effect on large pieces of cement. The rolling support component 3 can guide the grinding balls to roll on its surface when rising, thereby finely grinding some smaller cement particles stuck on the rolling support component 3. Under the guidance of the rolling support component 3, some grinding balls roll down into the ball-holding plate 5 and are carried to a higher position and thrown out. By setting the rolling support component 3 and the ball-holding plate 5, the efficiency can be improved in both grinding and crushing aspects, thereby improving the grinding and crushing efficiency through combination.
[0030] Figure 4 What is shown is only one set of lining shapes; the inside of barrel 2 is... Figure 4 The arrangement is equidistant.
[0031] Example 2: Refer to Figures 1-5 Similar to Embodiment 1, but further: the rolling support assembly 3 includes a first support plate 31 and a guide support plate 32, the guide support plate 32 extending to the ball-holding plate 5. Grinding protrusions 33 are provided on the first support plate 31 and the guide support plate 32. When the grinding ball rolls on the first support plate 31 and the guide support plate 32, the grinding ball crushes and breaks down fine particles. Guide inclined surfaces 34, which slope to both sides, are provided on the first support plate 31 and the guide support plate 32. 4 is used to guide large pieces of cement to slide to the boss liner 4 and the ball-holding plate 5 for crushing. The ball-holding plate 5 is a V-shaped design. The ball-holding plate 5 is provided with an embedded inclined surface 52 to transport grinding balls to a higher position for throwing. The top of the ball-holding plate 5 is provided with a crushing protrusion 51 for crushing block cement. The barrel body 2 is connected to the discharge pipe 24. The discharge pipe 24 is provided with a screen 241 and a hopper 23. The barrel body 2 is provided with a feed pipe 25. The feed pipe 25 is provided with a threaded conveying blade 251.
[0032] In this utility model, such as Figure 5As shown, the first support plate 31 and the guide support plate 32 together constitute the rolling support assembly 3. When the barrel 2 rotates, some grinding balls slide from the first support plate 31 to the guide support plate 32, and then fall onto the ball-holding plate 5 through the guide support plate 32. The first support plate 31 and the guide support plate 32 are provided with small grinding protrusions 33, so that some fine cement is stuck on them. When the grinding balls roll over, they are ground with the cement. The first support plate 31 and the guide support plate 32 are provided with guide inclined surfaces 34 that are inclined to both sides, so as to guide large cement blocks to roll towards the protrusion liner plate 4 and the ball-holding plate 5 to complete the crushing step.
[0033] The ball-holding plate 5 has an inwardly recessed inclined surface 52, which allows the ball-holding plate 5 to carry the grinding ball to a higher height for dropping, thereby improving the crushing effect of the grinding ball. The ball-holding plate 5 has a hemispherical crushing protrusion 51, which makes it easier for some large blocks of cement to be crushed when they come into contact with the crushing protrusion 51 and are hit by the grinding ball.
[0034] like Figures 1 to 3 As shown, the power source for driving the rotation of the barrel 2 is provided by the energy-saving geared motor on the right. The cement ground into powder enters the hopper 23 and is discharged through the screen 241 on the discharge pipe 24. The feed pipe 25 is equipped with threaded conveying blades 251, so that the user only needs to put the cement into the feed pipe 25, and the cement can be carried into the barrel 2 by the rotation of the barrel 2.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
