Grinding machine can be divided into ball mill, column mill, rod mill, tube mill, autogenous mill, mortar roller mill, vertical mill, multi-layer vertical mill and vertical roller mill according to the different grinding materials.

[0003] The existing grinding devices generally grind directly and cannot carry out a step-by-step grinding process for the material, which is not conducive to grinding large-particle materials into powder. For some materials with slightly larger particles, it is not easy for them to fall into the grinding area, which will greatly affect the grinding efficiency of the material. Some large-particle materials cannot even fall into the grinding area and cannot be ground smoothly. In view of this, we propose a grinding device with a screening structure. Utility Model Content

[0015] 1. The utility model is provided with a grinding assembly. The funnel grinding chamber in the grinding assembly sleeve and the grinding shaft are combined to form a material grinding processing area. The spacing between the matching spiral leaves on the inner wall of the funnel grinding chamber and the active spiral leaves on the grinding shaft decreases from top to bottom.

This can ensure stable and rapid grinding of large-particle materials and improve the grinding effect of the device on materials. The utility model can perform stable and efficient grinding of large-particle materials.

[0016] 2. The sleeve of the utility model is provided with an installation cavity, an electric heating plate, a first mesh hole and a second mesh hole. When grinding materials, for some materials with high humidity, during the process of grinding the materials by the grinding assembly, the electric heating plate inside the installation cavity heats the inside of the funnel grinding cavity, and the heat inside the installation cavity can directly enter the inside of the funnel grinding cavity through the first mesh hole, thereby accelerating the heating effect of the inside of the funnel grinding cavity. Therefore, the material is dried during the material grinding process to avoid the material from adhering to the grinding assembly, and the heat inside the installation cavity can quickly heat the bottom of the powder storage cylinder through the second mesh hole, thereby realizing secondary drying of the ground material, ensuring the dryness of the powder and avoiding the agglomeration of the powder.

[0024] In a specific embodiment, the grinding assembly 5 includes a sleeve 6 and a grinding shaft 7. A through-shaped funnel grinding chamber 601 is provided inside the sleeve 6, and a matching spiral leaf 602 is provided on the inner wall of the funnel grinding chamber 601. The grinding shaft 7 is vertically arranged inside the funnel grinding chamber 601, and the grinding shaft 7 is symmetrical with the center of the funnel grinding chamber 601. An active spiral leaf 701 is arranged on the grinding shaft 7, and the active spiral leaf 701 and the matching spiral leaf 602 are staggered. When the grinding shaft 7 rotates, the matching spiral leaf 602 cooperates with the active spiral leaf 701 to grind the material. Because the funnel grinding chamber 601 is funnel-shaped, the spacing between the matching spiral leaf 602 and the active spiral leaf 701 decreases from top to bottom, until the matching spiral leaf 602 and the active spiral leaf 701 at the bottom are staggered and overlapped with each other to complete the thorough grinding of the material. Therefore, the whole process adopts a step-by-step grinding work, and the large particle material can be ground from large to small until it is ground into powder, which can ensure the stability and efficiency of the whole grinding process.

[0025] Specifically, the funnel grinding chamber 601 is composed of an inverted frustum cavity and a cylindrical cavity, the top of the cylindrical cavity is connected with the bottom of the inverted frustum cavity, the material is ground gradually inside the inverted frustum cavity, and then enters the cylindrical cavity for grinding for a period of time.

[0026] Furthermore, a servo motor 702 is arranged at the bottom end of the grinding shaft 7. The servo motor 702 is fixedly installed at the center of the inner bottom of the cylinder 4. The servo motor 702 is used to drive the grinding shaft 7 to rotate.

[0027] Furthermore, a bearing is arranged on the top of the grinding shaft 7, and a number of reinforcement rods 703 are arranged at equal intervals on the outer ring of the bearing, and the end of the reinforcement rod 703 facing away from the bearing is fixedly connected to the top of the inner wall of the funnel grinding chamber 601. The bearing cooperates with the reinforcement rod 703 to stabilize the top of the grinding shaft 7 to ensure the stability of the rotation of the grinding shaft 7.

[0028] It is worth noting that a number of support blocks 605 are arranged at equal intervals inside the installation cavity 603 , and the support blocks 605 are staggered from the electric heating plate 604 . The support blocks 605 are used to support and reinforce the installation cavity 603 .

[0029] In addition, a ring seat 608 is arranged around the top of the sleeve 6, and the inner hole of the ring seat 608 is funnel-shaped. The funnel-shaped inner hole of the ring seat 608 can ensure that the material falls smoothly into the funnel grinding chamber 601 of the sleeve 6, and prevent part of the material from falling onto the top of the sleeve 6.

[0030] In the utility model, a mounting cavity 603 is arranged around the inside of the sleeve 6, and the mounting cavity 603 is covered on the outside of the funnel grinding cavity 601, and a plurality of electric heating plates 604 are arranged at equal intervals inside the mounting cavity 603, a plurality of first mesh holes 606 are arranged at equal intervals around the top of the funnel grinding cavity 601, and the first mesh holes 606 are connected to the mounting cavity 603, and a plurality of second mesh holes 607 are arranged at equal intervals around the bottom of the mounting cavity 603, and the second mesh holes 607 are connected to the inner cavity of the cylinder 4, when the material falls into the inner grinding cavity 601 of the sleeve 6, the material is ground. During the grinding process, the electric heating plate 604 is powered on to generate heat, and the inside of the funnel grinding chamber 601 is heated. The heat of the installation chamber 603 can quickly enter the inside of the funnel grinding chamber 601 through the first mesh 606, accelerating the heating of the inside of the funnel grinding chamber 601, achieving drying of the material during grinding, and avoiding the adhesion effect of the material due to moisture. The heat inside the installation chamber 603 enters the storage chamber through the second mesh 607, and the material of the grinding component inside the storage chamber is dried for a second time, avoiding the agglomeration of the material of the grinding component inside the storage chamber. The utility model can grind large-particle materials step by step through the grinding component 5, solving the technical problem that the grinding device is not conducive to grinding large-particle materials into powder.

[0031] Working principle: When grinding the material, first add the material to the screening machine 2, the screening machine 2 will screen out the waste material in the material, and the screened material will fall into the grinding component 5 inside the cylinder 4 of the grinding structure 3;

[0032] Secondly, when the material falls into the grinding assembly 5, the servo motor 702 drives the grinding shaft 7 to rotate, and the matching spiral blades 602 and the active spiral blades 701 in the funnel grinding chamber 601 cooperate to grind the material. Because the funnel grinding chamber 601 is funnel-shaped, the spacing between the matching spiral blades 602 and the active spiral blades 701 decreases from top to bottom, until the matching spiral blades 602 and the active spiral blades 701 at the bottom are staggered and overlapped with each other, completing the thorough grinding of the material. The ground material falls into the storage chamber, and then the discharge door 401 is opened to take out the divided material in the storage chamber.

[0033] Finally, when the material falls into the funnel grinding chamber 601 of the sleeve 6 for grinding, the electric heating plate 604 is energized to generate heat, thereby heating the inside of the funnel grinding chamber 601, and the heat from the mounting chamber 603 can quickly enter the funnel grinding chamber 601 through the first mesh hole 606, thereby accelerating the heating of the inside of the funnel grinding chamber 601, thereby achieving drying of the material during grinding, thereby avoiding adhesion of the material due to moisture, and the heat from the inside of the mounting chamber 603 enters the storage chamber through the second mesh hole 607, thereby performing secondary drying on the ground component material inside the storage chamber, thereby avoiding agglomeration of the ground component material inside the storage chamber.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes.
