Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and more specifically, to a multi-stage crushing device for recycled pig iron. Background Technology

[0002] Current crushing equipment can generally only perform preliminary crushing of materials and does not have the function of multi-stage crushing. If the materials are not crushed finely enough, the fermentation efficiency and fermentation effect cannot be improved, and the subsequent granulation process will be more complicated. In view of this, we propose a multi-stage crushing equipment.

[0003] To address the aforementioned problems, patent document publication number CN220027142U discloses a multi-stage crushing device, comprising a machine body. Support legs are fixedly installed at the bottom of the machine body. A rectangular plate sidewall is fixedly connected to the sidewall of the machine body. A reduction motor is fixedly installed at the top of the rectangular plate. A crushing roller is fixedly installed at the output end of the reduction motor via a coupling. The arc-shaped outer wall of the crushing roller is rotatably connected to the inside of the sidewall of the machine body. This multi-stage crushing device, to better perform multi-stage crushing of materials, incorporates a crushing mechanism. When the reduction motor is started, in conjunction with the drive pulley and horizontal transmission belt, two sets of crushing rollers and roller heads rotate towards each other, thus initially crushing the material. Further, in conjunction with a small pulley, vertical transmission belt, and large pulley, the large crushing roller rotates, thereby cooperating with the L-shaped inclined block to perform secondary crushing of the material, thus achieving the effect of multi-stage crushing.

[0004] However, it still has some shortcomings in actual use. For example, although the crushing equipment is equipped with a screening component that can perform preliminary screening of materials, it cannot adjust the size of the raw materials to be screened, and cannot meet different screening needs, which makes it inconvenient to use.

[0005] Therefore, a multi-stage crushing function for recycled pig iron is proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-stage crushing device for recycled pig iron, which solves the problem that although the prior art crushing device is equipped with a screening component and can perform preliminary screening of materials, it cannot adjust the size of the screening raw materials and cannot meet different screening needs.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-stage crushing device for recycled pig iron, comprising...

[0008] Equipment casing;

[0009] An adjustable screening component is disposed at the bottom of the device housing;

[0010] A crushing assembly, wherein the crushing assembly is disposed inside the equipment housing;

[0011] The adjustable screening assembly includes a fixed ring, a motor fixedly mounted on the side of the fixed ring, a gear fixedly mounted on the output end of the motor, a movable ring above the fixed ring, the top of the movable ring being rotatably connected to the bottom of the equipment housing, a toothed ring fixedly mounted on the outer surface of the movable ring, the toothed ring meshing with the gear, screens installed inside both the fixed ring and the movable ring, a pulley fixedly mounted on the bottom of the movable ring, and a groove formed on the top of the fixed ring, the inside of the groove being slidably connected to the bottom of the pulley.

[0012] The crushing assembly includes a second motor, a second gear, and a crushing roller. The second motor is fixedly installed on one side of the equipment housing. There are two second gears that mesh with each other. One side of one of the second gears is fixedly connected to the output end of the second motor. Crushing rollers are fixedly installed on the sides of both second gears away from the second motor. The ends of the crushing rollers away from the second gears are rotatably connected to the inside of the equipment housing.

[0013] It also includes a dust-blocking component, which is disposed on the top of the equipment housing.

[0014] The dust-blocking assembly includes a fixed plate and a rotating shaft. The two ends of the fixed plate are fixedly connected to the inside of the equipment housing. A sliding column is slidably connected to the top of the fixed plate. A connector is fixedly installed at the top of the sliding column. A spring is fixedly connected to the top of the fixed plate. The top of the spring is fixedly connected to the bottom of the connector. The two ends of the rotating shaft are rotatably connected to the inside of the equipment housing. A forked block is fixedly sleeved on the outer surface of the rotating shaft. The lower part of the forked block is slidably connected to the top of the connector. A baffle is fixedly installed at the top of the forked block.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] In the above scheme, an equipment shell, an adjustable screening component, and a crushing component are set up. Recycled pig iron is put into the equipment shell, and the second motor is turned on. The second motor drives the second gear to rotate, which in turn drives the crushing roller to crush the recycled pig iron. The crushed recycled pig iron will fall into the adjustable screening component. The first motor is turned on, and the first motor drives the first gear to rotate. The first gear then drives the movable ring through meshing with the gear ring. At this time, the pulley will slide inside the slide groove, causing the movable ring to rotate and change the size of the overlapping part of the two screens, thereby changing the size of the pig iron fragments intercepted by the two screens. Through the above structure, the size of the screened pig iron fragments can be adjusted at will according to the needs, so as to meet the effect of various processing requirements.

[0017] When the recycled pig iron is fed into the equipment casing, it first rests on the baffle. The baffle rotates to both sides due to gravity, and the rotating shaft also drives the forked block to rotate. When the forked block rotates, it presses the connecting piece downward. At this time, the sliding column slides inside the fixed plate, and the spring tightens. After the recycled pig iron passes through the gap and through the baffle, the spring rebound force will cause the connecting piece to move upward, so that the forked block returns to the horizontal position. The baffle will then cover the top of the equipment casing. Through the above structure, the top of the equipment casing is covered when the material is unloaded, preventing a large amount of dust from overflowing during crushing, thus achieving the effect of protecting the environment.

[0034] The crushing component 3 includes a second motor 31, a second gear 32, and a crushing roller 33. The second motor 31 is fixedly installed on one side of the equipment housing 1. There are two second gears 32, which mesh with each other. One side of one of the second gears 32 is fixedly connected to the output end of the second motor 31. The crushing roller 33 is fixedly installed on the side of each of the two second gears 32 away from the second motor 31. The end of the crushing roller 33 away from the second gear 32 is rotatably connected to the inside of the equipment housing 1.

[0035] It also includes a dustproof component 4, which is disposed on the top of the equipment housing 1.

[0036] The dust-blocking assembly 4 includes a fixed plate 41 and a rotating shaft 45. The two ends of the fixed plate 41 are fixedly connected to the inside of the equipment housing 1. A sliding column 42 is slidably connected to the top of the fixed plate 41. A connector 43 is fixedly installed at the top of the sliding column 42.
