Description

Technical Field

[0001] The utility model belongs to the technical field of mineral powder vertical mills, in particular to a mineral powder vertical mill device with a dustproof function. Background Art

[0002] After the ore is collected, there will be a lot of residues left. In this way, the residues also contain rich mining resources. In order to avoid waste, the slag needs to be recycled and crushed, and a vertical mill is needed for processing; in the grinding process, a series of measures are often taken to enhance the dust prevention effect. For example, high-efficiency dust removal equipment, such as a vertical mill dust collector, is equipped to capture and collect the generated dust, further ensuring the cleanliness of the production environment and dust control;

[0003] At present, most of the existing grinding methods are to directly put the slag into the equipment. However, the slag varies in size, and some larger pieces will bump against the internal components, which is easy to increase wear and reduce the service life, which is not conducive to the long-term stable use of the equipment.

[0004] In order to solve the above problems, the present application proposes a mineral powder vertical grinding device with dust prevention function. Utility Model Content

[0005] The utility model aims to provide a mineral powder vertical grinding device with dust-proof function, which solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a mineral powder vertical mill device with dust-proof function, comprising: a vertical mill, a top cover and a feeding hopper at its upper end, wherein a driving motor is arranged at one side of the upper end of the top cover adjacent to the feeding hopper; a positioning seat is arranged at the upper end of the vertical mill, the positioning seat is located between the vertical mill and the top cover, a rotating seat for receiving ore blocks is rotatably installed on the inner side of the positioning seat, a crushing hammer for crushing the ore blocks to form pretreatment is arranged on the inner side of the rotating seat; an adapter block is rotatably installed at the inner ring position of the positioning seat, and a clamping block engaged with the inner side of a groove at the upper end of the adapter block is arranged at the lower end of the rotating shaft of the driving motor.

[0008] Furthermore, a partition is provided at the lower end of the rotating seat, and a crushing hammer is installed through a pull rope on the inner side thereof, and a screen plate is provided between adjacent partitions.

[0009] Furthermore, a bottom plate is provided on the inner side of the lower end of the partition to prevent the ore blocks from falling directly.

[0010] Furthermore, the outer side of the rotating seat is rotatably connected with the positioning seat through a rotating frame, and a transmission gear is provided at the lower end of the adapter block to form a meshing connection with the rotating frame.

[0011] Furthermore, a limiting groove for installing the rotating frame is opened on the inner side of the positioning seat, and one end of the limiting groove is an open structure for placing the meshing connection part between the transmission gear and the rotating frame.

[0012] Furthermore, a protruding annular plate is provided on the outer side of the adapter block to form a rotational connection with the positioning seat.

[0013] Furthermore, the sieve plate and the bottom plate are both large-mesh structures for easy discharge.

[0014] The utility model has the following beneficial effects:

[0015] The utility model receives the ore block through the rotating seat and then swings the crushing hammer to make it collide with each other, and the ore block is crushed into small block structures and then discharged through the screen plate. Compared with the existing grinding method, the ore block can be pre-processed when feeding, avoiding the situation that the ore block is too large to wear the internal components, thereby extending the service life of the equipment and maintaining the stability of the long-term grinding operation of the equipment;

[0016] The utility model can directly combine the positioning seat between the vertical mill and the top cover through the protruding part on the outer side of the positioning seat when installing the top cover, so that the clamping block is engaged with the groove on the upper end of the adapter block. After this arrangement, the pretreatment mechanism can be quickly installed and disassembled, which is convenient for maintenance and subsequent cleaning processes.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] This embodiment provides a pretreatment mechanism for grinding ore blocks, so that the slag is crushed by the crusher 8 when feeding, reducing the wear of the internal components of the vertical mill 1, thereby extending the service life and stable performance of the vertical mill 1.

[0032] Among them, a partition 6 is provided at the lower end of the rotating seat 5, and a crushing hammer 8 is installed through a pull rope 10 inside the partition 6. A screen plate 7 is provided between adjacent partitions 6. When the rotating seat 5 rotates, the crushing hammer 8 is driven to rotate through the pull rope 10 using the rotational force.

[0033] A bottom plate 9 is provided on the inner side of the lower end of the partition 6 to prevent the ore blocks from falling directly, thereby forming a graded material discharge so that the ore blocks exceeding a predetermined size cannot fall directly.

[0034] The outer side of the rotating seat 5 is rotatably connected with the positioning seat 4 through the rotating frame 12. The lower end of the adapter block 14 is provided with a transmission gear 11 to form a meshing connection with the rotating frame 12. The outer side of the rotating frame 12 is a protruding toothed structure.

[0035] Among them, a limiting groove 13 for installing the rotating frame 12 is opened on the inner side of the positioning seat 4. One end of the limiting groove 13 is an open structure for placing the meshing connection part between the transmission gear 11 and the rotating frame 12, and at the same time, it also forms a limit for the transmission gear 11 to prevent vibration.

[0036] Among them, a protruding annular plate is arranged on the outer side of the adapter block 14 to form a rotation connection with the positioning seat 4.

[0037] Among them, the sieve plate 7 and the bottom plate 9 are both large mesh structures for easy discharge of materials.

[0038] It can be understood that the utility model can automatically pre-treat the slag when it is added, so that it can be crushed into ore blocks of predetermined size, which is convenient for grinding it. At the same time, it prevents damage to the internal components of the vertical mill 1 and improves the grinding efficiency, which is conducive to efficient and stable grinding operations.

[0039] A specific application of the operation process of this embodiment is: when in use, first install the positioning seat 4 between the vertical mill 1 and the top cover 2, and make the clamping block 15 engage with the upper end groove of the adapter block 14 near the inner circle position of the positioning seat 4. At this time, the drive of the motor can drive the transmission gear 11 to rotate through the adapter block 14, which is conducive to the meshing structure between its outer side and the rotating frame 12 to drive the rotating seat 5 to rotate, so that the crushing hammer 8 is thrown up and hits the ore block to crush it to form a pre-treatment. At this time, the ore block is crushed and discharged downward through the screen plate 7 and the bottom plate 9 for grinding without significantly wearing its components. While improving the service life of the internal components of the vertical mill 1, it also improves the grinding efficiency.
