Description

Technical Field

[0001] This utility model relates to a particle size-optimized calcium aluminate binder preparation device, belonging to the field of calcium aluminate binder grinding technology. Background Technology

[0002] Calcium aluminate binder is a common additive used to bond different materials together, exhibiting excellent adhesion, water resistance, and corrosion resistance. It has a wide range of applications, primarily in building materials, refractory materials, ceramic materials, and electronic materials, to enhance the adhesion and water resistance of these materials.

[0003] Currently, the main production process of calcium aluminate binder is as follows: First, precise batching is carried out; then, the batched raw materials are wet-milled with water; next, they are separated by pressure filtration, dried, and pressed into a green body; then, the green body is calcined at high temperature, cooled, and crushed to obtain the calcium aluminate binder. In actual production, the final crushed calcium aluminate binder product usually has a large particle size and varies in size. If used directly, it will inevitably affect its workability. To ensure the workability of the calcium aluminate binder product, particle size optimization is currently commonly achieved through grinding. Ball mills are widely used by enterprises due to their advantages such as stable and reliable operation, strong adaptability, large grinding ratio, ability to operate in both dry and wet methods, and simple and durable structure.

[0004] Most existing ball mills use a single-inlet feeding method. For example, Chinese utility model patent CN222766424U discloses a ball mill for antimony ore beneficiation. This prior art involves adding material through a feed pipe mounted on the feed cover. After being added, the material accumulates at one end of the feed cover on the drum, hindering sufficient contact between the material and the grinding balls, thus resulting in low grinding efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a particle size-optimized calcium aluminate binder preparation device with high grinding efficiency.

[0006] The particle size-optimized calcium aluminate binder preparation device of this utility model includes a left support and a right support. A left bearing seat and a right bearing seat are fixedly connected to the left support and the right bearing seat, respectively. A discharge port and a feed port are rotatably connected to the left bearing seat and the right bearing seat, respectively. A frustum-shaped discharge cylinder is connected to the right end of the discharge port. A flange plate is fixedly connected to the feed port. A roller is fixedly connected between the flange plate and the discharge cylinder. The roller contains several grinding balls. An isolation structure is fixedly connected to the left end of the inner side of the roller. A discharge screw is provided correspondingly in the left end of the roller, the discharge cylinder, and the discharge port. A rotary drive assembly is connected to the roller. The left end of the feed port is connected to the isolation structure. A feed screw penetrating both ends of the feed port is provided. Multiple feed holes are provided in the feed port along the left and right directions.

[0007] Furthermore, the isolation structure includes a central disk, with several strip ribs fixedly connected between the central disk and the roller, and multiple layers of inner and outer circular retaining rings fixedly connected to the strip ribs.

[0008] Furthermore, the central disk is provided with positioning holes.

[0009] Furthermore, the roller is provided with an inspection port, and a protective door is connected to the corresponding inspection port.

[0010] Furthermore, the rotary drive assembly includes a gear ring frame fixedly connected to the roller and a motor and a gearbox fixedly connected to the left support. An external gear ring is mounted on the gear ring frame, the input shaft of the gearbox is connected to the rotating shaft of the motor, and a drive gear that meshes with the external gear ring is mounted on the output shaft of the gearbox.

[0011] Furthermore, a drive support is fixedly connected to the left support, and the output shaft of the gearbox is rotatably mounted on the drive support.

[0012] Working principle and process:

[0013] During operation, the motor activates, driving the drive gear through the reduction gearbox. This, in turn, drives the drum through the external gear ring and gear ring frame, causing the grinding balls to roll inside the drum. Material is added through the feed inlet. As the feed inlet rotates with the drum, the material falls evenly into the drum through multiple feed holes under the action of the feed screw, ensuring sufficient contact between the material and the grinding balls. The rolling grinding balls impact, squeeze, and grind the material, resulting in a fine and uniform powder. After grinding, the motor is reversed, causing the drum, discharge cylinder, and discharge port to reverse as well. Under the action of the discharge screw, the ground material passes through the isolation structure and is then discharged through the discharge cylinder and discharge port. The grinding balls remain inside the drum under the action of the isolation structure.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The particle size-optimized calcium aluminate binder preparation device of this utility model, by setting multiple feed holes on the feed inlet, allows the material to fall into the drum more evenly, which facilitates full contact between the material and the grinding balls, effectively improving the grinding efficiency of the material. The ground material has a smaller particle size and is more uniform in size, which effectively ensures the construction performance of the product. Attached Figure Description

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0022] Example 1:

[0023] like Figures 1 to 3As shown, the particle size-optimized calcium aluminate binder preparation device of this utility model includes a left support 1 and a right support 10. A left bearing seat 15 and a right bearing seat 11 are fixedly connected to the left support 1 and the right support 10, respectively. A discharge port 16 and a feed port 12 are rotatably connected to the left bearing seat 15 and the right bearing seat 11, respectively. A frustum-shaped discharge cylinder 17 is connected to the right end of the discharge port 16. A flange plate 14 is fixedly connected to the feed port 12. The flange plate 14 and the discharge cylinder... A roller 9 is fixedly connected between 17. The roller 9 contains several grinding balls 21. An isolation structure 19 is fixedly connected to the left inner side of the roller 9. A discharge spiral 18 is provided in the left end of the roller 9, the discharge cylinder 17 and the discharge port 16 respectively. The roller 9 is connected to a rotary drive assembly. The left end of the feed port 12 is connected to the isolation structure 19. A feed spiral 13 is provided in the feed port 12, which runs through both ends. Multiple feed holes 20 are provided on the feed port 12 along the left and right directions.

[0024] In use, the rotary drive component operates, driving the drum 9 to rotate, which in turn causes the grinding balls 21 to roll inside the drum 9. The material is added through the feed port 12. As the feed port 12 rotates with the drum 9, the material falls evenly into the drum 9 through multiple feed holes 20 under the action of the feed screw 13, facilitating full contact between the material and the grinding balls 21. The rolling grinding balls 21 impact, squeeze, and grind the material, thereby grinding the material into a powder with small and uniform particle size. After grinding, the rotary drive component reverses its operation, thereby driving the drum 9, the discharge cylinder 17, and the discharge port 16 to reverse their rotation. Under the action of the discharge screw 18, the ground material passes through the isolation structure 19 and is then discharged through the discharge cylinder 17 and the discharge port 16. The grinding balls 21 remain inside the drum 9 under the action of the isolation structure 19.

[0025] Example 2:

[0026] like Figures 1 to 4 As shown, based on Example 1,

[0027] Furthermore, the isolation structure 19 includes a central disk 22, with several strip ribs 23 fixedly connected between the central disk 22 and the roller 9. Multiple layers of inner and outer circular retaining rings 24 are fixedly connected to the strip ribs 23. The distance between the outermost circular retaining ring 24 and the roller 9, as well as the distance between two adjacent circular retaining rings 24, is smaller than the diameter of the grinding ball 21. Because the gaps formed between the roller 9, the strip ribs 23, and each circular retaining ring 24 are arc-shaped and have a large area, it facilitates the timely discharge of ground material, effectively improving material discharge efficiency.

[0028] Furthermore, the central disk 22 is provided with a positioning hole 25. The feed inlet 12 can be inserted into the positioning hole 25 to facilitate the positioning and installation of the feed inlet 12.

[0029] Furthermore, the roller 9 is provided with an inspection port, and a protective door 8 is connected to the inspection port to facilitate the maintenance of the components inside the roller 9.

[0030] Furthermore, the rotary drive assembly includes a gear ring frame 6 fixedly connected to the roller 9, a motor 4 fixedly connected to the left support 1, and a reduction gearbox 2. An external gear ring 7 is mounted on the gear ring frame 6. The input shaft of the reduction gearbox 2 is connected to the rotating shaft of the motor 4, and a drive gear 5 that meshes with the external gear ring 7 is mounted on the output shaft of the reduction gearbox 2. By controlling the operation of the motor 4, the drive gear 5 can be driven to rotate through the reduction gearbox 2, thereby driving the roller 9 to rotate through the external gear ring 7 and the gear ring frame 6. The structure is simple, the operation is stable, and it is easy to control.

[0031] Furthermore, a drive support 3 is fixedly connected to the left support 1, and the output shaft of the reduction gearbox 2 is rotatably mounted on the drive support 3. The drive support 3 effectively supports the output shaft of the reduction gearbox 2, thereby improving the structural stability of the drive gear 5.
