Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushing technology, and in particular to a multi-stage crushing device. Background Art
[0002] Crushing equipment is used to break large particles of material into smaller particles.
[0003] In existing crushing devices, the material is often passed through different crushing mechanisms in sequence during the crushing process to achieve gradual crushing. Regardless of the particle size of the material, a single channel is used to pass through different crushing mechanisms in sequence. For materials that have been crushed to the required particle size by the previous crushing mechanism, they still need to pass through the next crushing mechanism because they cannot be discharged, which greatly increases the crushing time of the material.
[0004] Therefore, existing crushing devices cannot screen and classify materials by particle size, nor can they remove materials that meet the particle size requirements in advance, which is not conducive to ensuring crushing efficiency. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0032] like Figure 1 As shown in Specific Embodiment 1, a multi-stage crushing device includes a primary crushing mechanism 1, a secondary crushing mechanism 2, and a tertiary crushing mechanism 3. The discharge end of the primary crushing mechanism 1 is connected to a guide mechanism 4 that slopes downward from left to right. The guide mechanism 4 includes a first vibrating screen plate 41, a second vibrating screen plate 42, and a third guide inclined plate 43 arranged sequentially from top to bottom. The discharge end of the primary crushing mechanism 1 is connected to the top of the first vibrating screen plate 41. The first vibrating screen plate 41 has a first screen hole, and the second vibrating screen plate 42 has a second screen hole. The inner diameter of the first screen hole is larger than the inner diameter of the second screen hole. The discharge end of the first vibrating screen plate 41 is connected to the feed inlet at the top of the secondary crushing mechanism 2 through a first conveying mechanism. The discharge end of the second vibrating screen plate 42 is connected to the feed inlet at the top of the tertiary crushing mechanism 3. The discharge end of the secondary crushing mechanism is connected to a transition connection channel 5. The transition connection channel 5 is provided with an upper vibrating screen plate 51 and a lower guide inclined plate 52 arranged vertically at intervals. The upper vibrating screen plate 51 has a third screen hole. The inner diameter of the third screen hole matches the inner diameter of the second screen hole. That is, the inner diameter of the third screen hole is equal to the inner diameter of the second screen hole. The discharge end of the upper vibrating screen plate 51 connects to the top feed inlet of the three-stage crushing mechanism 3. The discharge end of the two-stage crushing mechanism is directly opposite the top of the upper vibrating screen plate 51.
[0033] This invention enables screening and grading of materials at different particle sizes. The material obtained from the primary crushing mechanism 1, meeting the particle size requirements, is directly discharged through the third discharge inclined plate 43, without passing through the secondary crushing mechanism 2 or the tertiary crushing mechanism 3. Similarly, the material obtained from the secondary crushing mechanism 2, meeting the particle size requirements, is directly discharged through the lower discharge inclined plate 52, without passing through the tertiary crushing mechanism 3.
[0034] This device achieves three-stage crushing.
[0035] The crushing process of this device is as follows: First, the material is crushed through the primary crushing mechanism 1. Based on particle size, large particles pass through the first vibrating screen plate 41, medium particles pass through the first vibrating screen plate 41 and the second vibrating screen plate 42, and small particles pass through the first vibrating screen plate 41, the second vibrating screen plate 42, and the third discharge inclined plate 43. The large particles on the first vibrating screen plate 41 are conveyed to the secondary crushing mechanism 2 via the first conveying mechanism. The medium particles on the second vibrating screen plate 42 are introduced into the tertiary crushing mechanism 3. The small particles on the third discharge inclined plate 43 are directly discharged from the outlet end of the third discharge inclined plate 43.
[0036] The secondary crushing mechanism 2 crushes the fed material. The crushed material from the secondary crushing mechanism 2 is categorized by particle size: smaller particles pass through the upper vibrating screen plate 51 and the lower discharge inclined plate 52, while other particles pass through the upper vibrating screen plate 51. The upper vibrating screen plate 51 guides the material onto the tertiary crushing mechanism 3, and the lower discharge inclined plate 52 directly discharges the smaller particles from its outlet end.
[0037] The three-stage crushing mechanism 3 crushes the fed material; the crushed material is directly discharged from the discharge end of the three-stage crushing mechanism 3.
[0038] All materials that meet the particle size requirements are discharged through the third discharge inclined plate 43, the lower discharge inclined plate 52, and the discharge end of the three-stage crushing mechanism 3.
[0039] The discharge end of the secondary crushing mechanism 2 is connected to the vibrating screen plate 51.
[0040] The primary crushing mechanism 1 has two primary crushing rollers, the secondary crushing mechanism 2 has two secondary crushing rollers, and the tertiary crushing mechanism 3 has two tertiary crushing rollers. The distance between two primary crushing rollers is greater than the distance between two secondary crushing rollers, and the distance between two secondary crushing rollers is greater than the distance between two tertiary crushing rollers. By adjusting the distance between the crushing rollers, different crushing particle sizes can be achieved stepwise.
[0041] The first conveying mechanism is inclined upward from the discharge end of the first vibrating screen plate 41. The first conveying structure is an inclined feeder.
[0042] The first vibrating screen plate 41, the second vibrating screen plate 42, and the third guide inclined plate 43 all slope downwards from left to right. The upper vibrating screen plate 51 and the lower guide inclined plate 52 both slope downwards from right to left.
[0043] The second vibrating screen plate 42 is arranged symmetrically with the upper vibrating screen plate 51. The lower ends of the second vibrating screen plate 42 and the upper vibrating screen plate 51 are connected to the feed inlet at the top of the three-stage crushing mechanism 3. The discharge end of the three-stage crushing mechanism 3 is directly opposite the discharge end of the lower guide inclined plate 52 and the discharge end of the third guide inclined plate 43.
[0044] A vibration motor for striking the transition docking channel 5 is installed on the transition docking channel 5. Specifically, one vibration motor is used to strike the lower side of the upper vibrating screen plate 51, and another vibration motor is used to strike the lower guide inclined plate 52.
[0045] The material guiding mechanism 4 is equipped with a vibrating motor for striking the material guiding mechanism 4. Specifically, one vibrating motor is used to strike the lower side of the first vibrating screen plate 41, one vibrating motor is used to strike the lower side of the second vibrating screen plate 42, and one vibrating motor is used to strike the lower side of the third guide inclined plate 43.
[0046] The material guiding mechanism 4 includes an inclined cavity, with a first air intake 44 installed at the top of the cavity. The first air intake 44 is connected to a cloth bag through a first air intake pipe. A first air intake pump is installed on the first air intake pipe. A first vibrating screen plate 41, a second vibrating screen plate 42, and a third guide inclined plate 43 are installed inside the cavity. This facilitates the collection of dust within the material guiding mechanism 4.
[0047] A second air intake 54 is installed at the top of the transition docking channel 5, and the second air intake 54 is connected to a cloth bag through a second air intake pipe; a second air intake pump is installed on the second air intake pipe. An upper vibrating screen plate 51 and a lower guide inclined plate 52 are installed inside the cavity to facilitate the collection of dust in the transition docking channel 5.
