Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushing equipment technology, specifically a crushing device that can improve crushing efficiency. Background Technology
[0002] White fused alumina is a type of artificial abrasive. It contains more than 99% aluminum oxide (Al2O3) and small amounts of iron oxide, silicon oxide and other components, and is white in color. White fused alumina is made from industrial alumina powder as raw material, which is melted in an electric arc at a high temperature of more than 2000℃ and then cooled. After being crushed, shaped, magnetically separated to remove iron, and sieved into various particle sizes.
[0003] Patent (CN118403693B) discloses a crushing device for sintered white fused alumina, comprising: a support frame for supporting the equipment; and a crushing assembly for crushing white fused alumina, the crushing assembly being fixedly connected to the top of the support frame. The crushing assembly includes a crushing box fixedly connected to the top of the support frame, the crushing box being used for crushing and collecting white fused alumina. A crushing roller is rotatably connected to the inner surface of the crushing box. This invention relates to the field of white fused alumina production technology. In this crushing device for sintered white fused alumina, the rotating crushing roller crushes falling white fused alumina, preventing uncrushed white fused alumina from falling directly. A dust collection assembly collects dust generated during crushing on the crushing box. A guide plate inside the crushing box works in conjunction with a protective assembly and a screening assembly to guide and collect residual white fused alumina from screening, facilitating subsequent re-addition and crushing of the white fused alumina collected by the guide plate.
[0004] The white fused alumina sintering crushing equipment in the aforementioned patent only has one set of crushing components. Regardless of the particle size of the white fused alumina, it is crushed by this set of crushing components. However, when processing white fused alumina with a larger particle size, due to the surface particle size or surface shape, the white fused alumina will always roll and contact above the two crushing rollers and cannot enter the crushing channel between the two crushing rollers, which seriously affects the crushing effect of the equipment on white fused alumina. Utility Model Content
[0005] The purpose of this invention is to provide a crushing device that can improve crushing efficiency, so as to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a crushing device that can improve crushing efficiency, including a crushing box, wherein a first crushing component and a second crushing component are provided inside the crushing box, the first crushing component is located above the second crushing component, and a feeding component is provided inside the crushing box above the first crushing component and the second crushing component respectively, wherein the distance between the two first crushing rollers in the first crushing component is greater than the distance between the two second crushing rollers in the second crushing component, and the first crushing roller and the second crushing roller are parallel to each other.
[0007] Furthermore, the feeding assembly includes a protective cover and a rotatably connected bidirectional ball screw. The bidirectional ball screw is located below the protective cover, and a screw nut is movably fitted onto the outer wall of the bidirectional ball screw. A feeding rod is provided at the bottom of the screw nut, and the bidirectional ball screw is parallel to the first crushing roller.
[0008] Furthermore, the outer wall of the lead screw nut is symmetrically provided with sliders on both sides, and the inner wall of the protective cover is provided with a horizontal groove that matches the slider.
[0009] Furthermore, the first crushing assembly also includes a first motor, which is fixedly connected to one end of a first crushing roller via a reducer. The two first crushing rollers are connected by two gears, and the outer wall of the first crushing roller has a threaded groove structure.
[0010] Furthermore, the second crushing assembly also includes a second motor, which is fixedly connected to one end of a second crushing roller via a reducer. The outer wall of the second crushing roller has a toothed structure, and the toothed structures of the outer walls of the two second crushing rollers mesh with each other.
[0011] Furthermore, the crushing box has a feed inlet at the top center, and a rotatably connected support sleeve is horizontally arranged inside the feed inlet. The outer wall of the support sleeve is provided with several isolation plates, which are arranged radially on the outer wall of the support sleeve.
[0012] Furthermore, a receiving hopper is horizontally and slidably connected inside the crushing box below the second crushing component, and a pull rod is provided on the outer wall of the receiving hopper outside the crushing box.
[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0014] 1. This utility model, by setting up a first crushing component, a second crushing component, a feeding component, a first crushing roller, and a second crushing roller, allows for the initial crushing of white fused alumina by the first crushing component above the second crushing component inside the crushing chamber. The second crushing component then performs secondary crushing of the white fused alumina below the first crushing component. This step-by-step crushing process effectively adjusts the particle size of the white fused alumina entering the second crushing component, reducing or preventing large-diameter white fused alumina from directly entering the second crushing component for further crushing, thus ensuring rapid crushing of the white fused alumina. The material enters the crushing channel between the two second crushing rollers of the second crushing component, preventing white fused alumina from clogging the crushing channel and thus improving the equipment's crushing efficiency for white fused alumina. This ensures that white fused alumina enters the crushing channel normally for crushing and that the particle size of the crushed white fused alumina meets the requirements. The feeding component acts on the surface of the white fused alumina, repeatedly adjusting the position and angle of the white fused alumina at the top of the crushing channel, allowing the white fused alumina to enter the crushing channel more smoothly for crushing, preventing the white fused alumina from clogging the crushing channel, and effectively improving the crushing efficiency of white fused alumina.
[0015] 2. In this utility model, the protective cover in the feeding assembly provides protection above the bidirectional ball screw and screw nut, effectively preventing white fused alumina from falling directly onto the surface of the bidirectional ball screw and screw nut, thereby ensuring the normal operation of the bidirectional ball screw and screw nut. The rotational motion of the bidirectional ball screw drives the screw nut to perform horizontal reciprocating motion along the bidirectional ball screw, and the screw nut drives the feeding rod to perform horizontal reciprocating motion. The feeding rod performs horizontal reciprocating feeding of white fused alumina above the two crushing channels, which can realize rapid feeding adjustment of white fused alumina at the top of the crushing channels. The bidirectional ball screw can be driven by a motor alone, or it can be connected to the rotating motion component of the first crushing assembly or the second crushing assembly through a transmission assembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-6 This utility model provides a technical solution: a crushing device that can improve crushing efficiency, including a crushing box 1. The crushing box 1 is provided with a first crushing component 2 and a second crushing component 3. The first crushing component 2 is located above the second crushing component 3. Inside the crushing box 1, above the first crushing component 2 and the second crushing component 3, there are material feeding components 4 respectively. The distance between the two first crushing rollers 201 in the first crushing component 2 is greater than the distance between the two second crushing rollers 301 in the second crushing component 3. The first crushing rollers 201 and the second crushing rollers 301 are parallel to each other. The material feeding component 4 includes a protective cover 402 and a rotatably connected bidirectional ball screw 401. The bidirectional ball screw 401 is located below the protective cover 402. A screw nut 403 is movably fitted on the outer wall of the bidirectional ball screw 401. A material feeding rod 404 is provided at the bottom of the screw nut 403. The bidirectional ball screw 401 is parallel to the first crushing rollers 201.
[0026] In one embodiment, sliders 405 are symmetrically arranged on both sides of the outer wall of the lead screw nut 403, and a groove 406 matching the sliders 405 is horizontally arranged on the inner wall of the protective cover 402. When the bidirectional ball screw 401 rotates and drives the lead screw nut 403 to move, the sliders 405 and the inner side of the groove 406 limit the lead screw nut 403, which can effectively prevent the lead screw nut 403 from rotating and ensure that the lead screw nut 403 performs horizontal reciprocating motion.
[0027] In one embodiment, the first crushing assembly 2 further includes a first motor 202, which is fixedly connected to one end of a first crushing roller 201 via a reducer. The two first crushing rollers 201 are connected by two gears 203. The first motor 202 drives one first crushing roller 201 to rotate via the reducer. The first crushing roller 201 drives the other first crushing roller 201 to rotate via the transmission between the two gears 203. The two first crushing rollers 201 rotate in opposite directions, which can effectively ensure that the two first crushing rollers 201 cooperate to crush the white fused alumina. The outer wall of the first crushing roller 201 has a threaded groove structure. The threaded groove structure on the surface of the two first crushing rollers 201 can effectively perform spiral crushing of the white fused alumina entering between the two first crushing rollers 201. While crushing the white fused alumina, it can also drive the white fused alumina in a horizontal direction, so that the white fused alumina can enter between the two first crushing rollers 201 at different angles for crushing.
[0028] In one embodiment, the second crushing assembly 3 further includes a second motor 302, which is fixedly connected to one end of a second crushing roller 301 via a reducer. The outer wall of the second crushing roller 301 has a toothed structure, and the toothed structures of the outer walls of the two second crushing rollers 301 mesh with each other. The second motor 302 drives one of the second crushing rollers 301 to rotate via the reducer. The toothed structure on the surface of the second crushing roller 301 realizes the transmission of the two second crushing rollers 301 while crushing the white fused alumina, so that the two second crushing rollers 301 rotate in opposite directions, ensuring the crushing effect of the white fused alumina.
[0029] In one embodiment, the crushing chamber 1 has a feed inlet 101 at its top center. A rotatably connected support sleeve 102 is horizontally arranged inside the feed inlet 101. Several isolation plates 103 are arranged radially on the outer wall of the support sleeve 102. The feed inlet 101 is used to feed white fused alumina into the crushing chamber 1. After the white fused alumina is fed into the feed inlet 101, its gravity acts on the surface of the isolation plates 103, pressing them downwards. The isolation plates 103 rotate around the support sleeve 102, ensuring that the white fused alumina enters the crushing chamber 1 normally. Simultaneously, the multiple isolation plates 103 work together to isolate and seal the feed inlet 101, effectively preventing dust generated during crushing from flying out through the feed inlet 101. Additionally, the crushing chamber 1 can be equipped with a dust collection device to remove dust generated inside the crushing chamber 1.
[0030] In one embodiment, a receiving hopper 104 is horizontally and slidably connected inside the crushing box 1 below the second crushing component 3. A pull rod 105 is provided on the outer wall of the receiving hopper 104 outside the crushing box 1. The receiving hopper 104 is used to receive the white corundum processed by the second crushing component 3 inside the crushing box 1. The pull rod 105 facilitates the pushing and pulling operation of the receiving hopper 104, making it easy to pull the receiving hopper 104 out of the crushing box 1 or push it in.
[0031] The working principle of this utility model:
[0032] Refer to the instruction manual appendix Figures 1-6 This invention, by setting up a first crushing component 2, a second crushing component 3, a feeding component 4, a first crushing roller 201, and a second crushing roller 301, inside the crushing chamber 1, the first crushing component 2 performs preliminary crushing of white fused alumina above the second crushing component 3, and the second crushing component 3 performs secondary crushing of white fused alumina below the first crushing component 2. By performing step-by-step crushing of white fused alumina, the particle size of white fused alumina entering the second crushing component 3 can be effectively adjusted, which can effectively reduce or avoid large-diameter white fused alumina directly entering the second crushing component 3 for crushing, ensuring that white fused alumina quickly enters the crushing channel between the two second crushing rollers 301 of the second crushing component 3, avoiding white fused alumina clogging the crushing channel, thereby improving the crushing efficiency of the equipment for white fused alumina;
[0033] The distance between the two first crushing rollers 201 in the first crushing component 2 is set to be greater than the distance between the two second crushing rollers 301 in the second crushing component 3. This ensures that the first crushing roller 201 can process white fused alumina particles with a larger particle size, while the second crushing roller 301 can process white fused alumina particles with a smaller particle size. This ensures that white fused alumina can enter the crushing channel normally for crushing and that the particle size of the crushed white fused alumina meets the requirements.
[0034] Two feeding components 4 are respectively feeding the white fused alumina above the crushing channels of the first crushing component 2 and the second crushing component 3. The feeding components 4 can effectively feed the white fused alumina. When the white fused alumina cannot enter the crushing channel normally, the feeding components 4 act on the surface of the white fused alumina, which can make the white fused alumina switch positions and angles at the top of the crushing channel. The position and angle of the white fused alumina at the top of the crushing channel can be repeatedly adjusted. Since the sintered white fused alumina is mostly irregular in shape, the position and angle of the white fused alumina at the top of the crushing channel can be adjusted, so that the white fused alumina can enter the crushing channel more smoothly for crushing, avoiding the white fused alumina from blocking the crushing channel, and effectively improving the crushing efficiency of white fused alumina.
[0035] The protective cover 402 in the feeding assembly 4 provides protection above the bidirectional ball screw 401 and the screw nut 403, effectively preventing white fused alumina from falling directly onto the surfaces of the bidirectional ball screw 401 and the screw nut 403, thus ensuring the normal operation of the bidirectional ball screw 401 and the screw nut 403. The rotational motion of the bidirectional ball screw 401 drives the screw nut 403 to perform horizontal reciprocating motion along the bidirectional ball screw 401. The screw nut 403 drives the feeding rod 404 to perform horizontal reciprocating motion. The feeding rod 404 performs horizontal reciprocating feeding of white fused alumina above the two crushing channels, which can realize the rapid adjustment of white fused alumina at the top of the crushing channels. The bidirectional ball screw 401 can be driven by a motor alone, or it can be connected to the rotating motion component of the first crushing assembly 2 or the second crushing assembly 3 through a transmission assembly.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
