Description

Technical Field

[0001] The utility model relates to the technical field of vertical compound crushers, in particular to a vertical compound crusher with a multi-stage crushing structure. Background Art

[0002] Vertical compound crusher. It is a new type of fine crushing and coarse grinding product developed by integrating the technologies of similar crushers at home and abroad and optimizing the main technical parameters. It is mainly used for medium and small-scale crushing of cement raw materials and clinker, and provides an ideal fine crushing equipment for the technical transformation of cement plants or the construction of new cement production lines. It is also suitable for crushing other medium-hard ores such as iron ore, sandstone, gypsum, coal gangue, lump coal, etc. It has the characteristics of large crushing ratio, low energy consumption, stable operation, simple structure, easy operation and maintenance, and the outstanding features are: 1. It can design different layers and speeds according to customer requirements, which is very convenient to control the particle size of the discharge; 2. It has no screen, which can solve the blockage and the crushing problem of materials with high moisture content.

[0003] Since the ore needs to be crushed into a certain size, the existing vertical compound crusher needs to pre-process the material into a certain range of sizes when crushing the ore. If the size is too large, the ore cannot be put in, which results in a smaller range of ore sizes that need to be crushed, and small particles of gravel will be ejected during the processing of the ore, which will pose a safety hazard.

[0004] Therefore, those skilled in the art provide a vertical compound crusher with a multi-stage crushing structure to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 to Figure 5 In an embodiment of the utility model, a vertical compound crusher with a multi-stage crushing structure includes a vertical compound crusher body 1, a rotating shaft 2 is installed inside the body 1, a plurality of rotors 3 are arranged on the rotating shaft 2, the plurality of rotors 3 are arranged in a vertical direction, the diameters of the plurality of rotors 3 increase successively from top to bottom, a plate hammer 4 is installed on the rotor 3, a plurality of groups of lining plates 5 are provided on the inner wall of the body 1, the spacing between the plate hammer 4 and the relative lining plates 5 gradually decreases, a feeding assembly is installed on the top of the body 1, a plurality of protrusions 6 are provided on the lining plates 5, and the ends of the protrusions 6 are prism-shaped.

[0024] The main body 1 is a common vertical compound crusher on the market. The rotating shaft 2 is rotatably connected to the middle part of the main body 1, and the rotor 3 is fixed to the rotating shaft 2. Multiple rotors 3 are fixed on the rotating shaft 2 from top to bottom. The plate hammer 4 is fixedly installed on the outer side of the rotor 3, and the lining plate 5 is fixedly installed on the inner wall of the main body 1. The distance between the lining plate 5 and the plate hammer 4 decreases from top to bottom. Such an arrangement can enable the upper material to be initially crushed. Since the distance between the plate hammer 4 and the lining plate 5 on the same horizontal plane remains stable, the plate hammer 4 and the lining plate 5 will rotate relative to each other. The material is subjected to forces in multiple directions between the plate hammer 4 and the lining plate 5, which can facilitate the crushing of the material. After the upper material is crushed, its volume will decrease and enter between the plate hammer 4 and the lining plate 5 below it. After being crushed many times, the material will be crushed into smaller particles. The convex portion 6 can change the contact surface with the material, and at the same time can replace the lining plate 5 to crush the material, which is convenient for maintenance.

[0025] In one embodiment, specifically, the feed assembly includes two feed hoppers 7 installed on the top of the main body 1, and a barrier assembly for preventing materials from bursting out is installed inside the feed hopper 7; the barrier assembly includes two fixed shafts 8 installed on the inner wall of the feed hopper 7, and a baffle 9 is installed on the fixed shaft 8, and a rebound assembly is provided between the baffle 9 and the inner wall of the feed hopper 7. The feed hopper 7 is fixedly installed on the top of the main body 1, and the feed hopper 7 is connected to the inside of the main body 1. External materials can be transported to the inside of the main body 1 through the feed hopper 7 for crushing. The fixed shaft 8 is fixedly connected to the inner wall of the feed hopper 7, and the baffle 9 is hinged on the fixed shaft 8. The baffle 9 can cover the feed hopper 7 to prevent materials from splashing out during the crushing process.

[0026] Among them, the rebound component includes an arc sleeve 10 installed on the inner wall of the feed hopper 7, and an arc rod 11 is provided on the baffle 9. The arc rod 11 is slidably connected to the arc sleeve, and a spring 12 is provided inside the arc sleeve 10 to abut against the arc rod 11. The arc sleeve 10 is fixedly connected to the inner wall of the feed hopper 7, and the arc rod 11 is fixedly connected to the bottom of the baffle 9. The arc rod 11 is slidably connected to the arc sleeve 10, and the spring 12 is located inside the arc sleeve 10, which can facilitate the resetting of the baffle 9.

[0028] When the material is crushed, the material is first put into the main body 1 through the two feed hoppers 7. At this time, the material will cause the baffle 9 to rotate a certain angle due to its own gravity. During the rotation of the baffle 9, a gap for the material to pass through will be formed between the two baffles 9. When the material above the baffle 9 is reduced or there is no material, the spring 12 inside the arc sleeve 10 will rebound, and the cover plate will be reset under the action of the spring 12. The middle part of the feed hopper 7 will be blocked by the two baffles 9, and the material entering the interior will be crushed in the middle and upper part of the main body 1. The material crushed into smaller particles will move downward, and materials of different sizes can be crushed multiple times. After multiple stages of crushing, the material can be discharged from the discharge port 16.

[0029] In one embodiment, specifically, a buffer column 17 is provided at the end of the baffle 9, and the buffer column 17 can prevent the end of the baffle 9 from being damaged by impact.
