Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cement grinding production technology, and in particular relates to a cement grinding production device with shock absorption function. Background Technology
[0002] Cement grinding is a core step in cement manufacturing. Its main purpose is to grind raw materials such as clinker and gypsum to a suitable particle size to form a reasonable particle size distribution. This process increases the hydration surface area, accelerates the hydration rate, and optimizes the setting and hardening properties.
[0003] While current grinding equipment can crush raw materials, it generally employs a rigid connection structure. Vibrations generated during grinding operations are easily transmitted directly to the equipment casing and support structure through transmission components, leading to a decrease in overall equipment stability. Especially under high load operation, vibration-induced resonance can exacerbate mechanical wear, shorten the lifespan of critical components, and cause raw material splashing inside the grinding tank, resulting in material waste and safety hazards.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a cement grinding production device with shock absorption function, in order to achieve a more practical value. Utility Model Content
[0005] The main technical problem solved by this utility model is to provide a cement grinding production device with shock absorption function.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A cement grinding production device with shock absorption function includes a grinding tank, a top cover detachably provided at the upper end of the grinding tank, grinding balls rotatably disposed inside the cavity of the grinding tank, a mounting frame provided above the top cover, a driving device mounted on the mounting frame, the output shaft of the driving device passing through the top cover and connected to the grinding balls, and the driving device being able to drive the grinding balls to rotate.
[0008] A lifting and shock absorption mechanism is provided between the mounting frame and the top cover.
[0009] Furthermore, the lifting and shock absorption mechanism includes a traction return spring assembly and a hexagonal prism. The hexagonal prism is located at the bottom center of the mounting frame, and the traction return spring assembly includes multiple traction springs. The upper and lower ends of each traction spring are respectively connected to the mounting frame and the top cover.
[0010] The hexagonal prism has a shaft hole through which the output shaft passes, and the top cover has a through hole for the hexagonal prism to slide up and down.
[0011] Furthermore, the traction return spring assembly includes six traction springs, which are evenly distributed circumferentially on the outer side of the hexagonal prism.
[0012] Furthermore, the outer wall of the grinding ball has a spirally arranged oblique protrusion, which allows the grinding ball to pull the raw material to the bottom when rotating, thereby making the grinding more efficient and concentrated.
[0013] Furthermore, the top of the grinding ball has a ramp cover, and the lower end of the output shaft is fixedly connected to the upper end of the ramp cover.
[0014] Furthermore, the driving device is a grinding motor.
[0015] Furthermore, a material storage chamber is provided on the side of the top cover facing the grinding tank, and the material storage chamber is connected to the grinding tank.
[0016] Furthermore, the lower end of the grinding tank is provided with a discharge port. The discharge port is equipped with a valve device that can open or close the discharge port.
[0017] Furthermore, the top cover has horizontally extended frame plates on both sides.
[0018] The beneficial technical effects of this utility model are:
[0019] 1. The grinding structure uses a grinding jar and grinding balls of the same size as the main grinding structure. The rotation of the grinding balls continuously grinds the raw materials in the grinding jar to achieve the particle precision required for grinding production. The grinding balls are powered by an electric motor, which can adjust the grinding rate according to the needs to better meet the grinding requirements. The surface of the grinding balls is provided with oblique protrusions, which can drive the raw materials to gather at the bottom when rotating, thereby making the grinding more efficient and concentrated.
[0020] Second, the overall structure of the grinding balls extends to the mounting frame, which is connected to the top cover through a traction return spring group. This can buffer the vibration force generated during grinding. Under the limitation of the hexagonal prism on the bottom side, the lifting frame only supports the vertical lifting and sliding structure. When the vibration force is transmitted vertically, it cooperates with multiple sets of vertically set traction return springs on the outside to better receive the vibration force, ensuring a better shock absorption effect during grinding. The equipment has high reliability and stability. Attached Figure Description

[0026] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0027] This specific embodiment discloses in detail a cement grinding production apparatus with vibration damping function, such as... Figures 1 to 3 As shown, the device includes a grinding jar 2, a top cover 1 that is detachably mounted on the upper end of the grinding jar 2 by bolts, grinding balls 703 that are rotatably disposed inside the cavity of the grinding jar 2, a mounting frame 3 that is disposed above the top cover 1, a drive device 4 that is mounted on the mounting frame 3 by bolts, the output shaft 7 of the drive device 4 passing through the top cover 1 and connected to the grinding balls 703, and the drive device 4 that can drive the grinding balls 703 to rotate; a lifting and shock absorption mechanism is provided between the mounting frame 3 and the top cover 1.
[0028] The lifting and shock absorption mechanism includes a traction return spring assembly 6 and a hexagonal prism 701. The hexagonal prism 701 is welded to the bottom center of the mounting frame 3. The traction return spring assembly 6 includes six traction springs, which are evenly distributed circumferentially on the outside of the hexagonal prism 701. The upper and lower ends of each traction spring are welded to the mounting frame 3 and the top cover 1, respectively. The hexagonal prism 701 has a shaft hole for the output shaft 7 to pass through, and the top cover 1 has a through hole for the hexagonal prism 701 to slide up and down.
[0029] The outer wall of the grinding ball 703 has a spirally arranged oblique protrusion 704. When the grinding ball 703 rotates, it can drive the raw material to gather at the bottom, thereby making the grinding more efficient and concentrated. The top of the grinding ball 703 has a ramp cover 702, and the lower end of the output shaft 7 is fixedly connected to the upper end of the ramp cover 702.
[0030] Preferably, the drive device 4 is a grinding motor.
[0031] Preferably, the top cover 1 has a storage chamber 8 on the side facing the grinding tank 2, and the storage chamber 8 is connected to the grinding tank 2. The device also includes a feeder to transport the raw materials inside the storage chamber into the grinding tank.
[0032] Preferably, the lower end of the grinding tank 2 is provided with a discharge port 9. The discharge port 9 has a valve device that can open or close the discharge port 9.
[0033] Preferably, the top cover 1 has horizontally welded extension frame plates 5 on both sides.
[0034] Working Principle: The grinding tank 2 and grinding balls 703, which are sized to match it, serve as the main grinding structure. The rotation of the grinding balls 703 continuously grinds the raw materials inside the grinding tank 2 to achieve the required particle size precision. The grinding balls 703 are powered by a grinding motor, allowing for adjustable grinding speeds to better meet grinding needs. The surface of the grinding balls 703 features inclined protrusions 704, which, during rotation, draw the raw materials towards the bottom, resulting in better and more concentrated grinding. A mounting frame 3 extends from the overall structure of the grinding balls 703. The mounting frame 3 is connected to the top cover 1 via a traction return spring group 6, which buffers the vibration generated during grinding. The lifting frame 3, limited by the hexagonal prism 701 on the bottom side, only supports vertical sliding, allowing the vibration to be transmitted vertically. This, combined with multiple vertically arranged traction return springs on the outside, better receives the vibration, ensuring good shock absorption during grinding and high equipment reliability and stability.
