Abstract
Description
Technical Field
[0001] This utility model relates to the field of brown fused alumina processing technology, specifically to a lifting mechanism for crushing brown fused alumina. Background Technology
[0002] Brown fused alumina, also known as corundum, is a brownish-red synthetic corundum produced by melting and reducing bauxite, coke (or anthracite), and iron filings in an electric furnace at temperatures above 2000 degrees Celsius. It has a high alumina content, relatively low impurity content, and a relatively complete crystal structure, giving it excellent physical and chemical properties. Brown fused alumina powder can be used for free grinding in fields such as cathode ray tubes, optical glass, single-crystal silicon, lenses, watch glass, crystal glass, and jade. It is a widely used high-grinding material in China.
[0003] In the existing technology, the lifting and operation of brown fused alumina before crushing usually involves workers directly dumping large quantities of brown fused alumina onto a conveyor belt, which then lifts and transports the brown fused alumina to the crushing equipment area.
[0004] There are some problems. The particles in the unscreened brown fused alumina material may be of different sizes. In the subsequent processing, large particles may not be fully crushed, resulting in large particles in the final product and affecting the particle size uniformity of the product. To address this, we propose a lifting mechanism for crushing brown fused alumina. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a lifting mechanism for pulverizing brown fused alumina. While lifting the brown fused alumina, it also screens the brown fused alumina. The screened brown fused alumina has a uniform particle size, which allows it to make more full contact with the pulverizing parts when it enters the pulverizing equipment. This facilitates the uniform application of pulverizing force to the material and improves the pulverizing efficiency of the brown fused alumina. This can effectively solve the problems in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a lifting mechanism for pulverizing brown fused alumina, comprising a frame, a transfer device for lifting is provided between the left and right inner walls of the frame, a temporary storage bin is provided at the front end of the frame, and a shaking mechanism is also included.
[0007] The shaking mechanism includes a mounting plate, bosses, a movable plate, and a counter-mounting platform. Mounting plates are provided on the left and right inner walls of the frame. Bosses are evenly distributed on the opposing inner surfaces of the two mounting plates. A movable plate is located between the two mounting plates. The movable plate is installed in conjunction with the transfer equipment. A screening hopper is slidably connected to the front side of the movable plate. Counter-mounting platforms are provided on the front ends of the left and right sides of the screening hopper. These platforms cooperate with the adjacent horizontal bosses. While lifting brown fused alumina, the mechanism also screens the brown fused alumina. The screened brown fused alumina has a uniform particle size, allowing for more thorough contact with the crushing components when it enters the crushing equipment. This facilitates the uniform application of crushing force to the material, improving the subsequent crushing efficiency of the brown fused alumina.
[0008] Furthermore, the shaking mechanism also includes a sliding groove, and the front side of the moving plate is provided with evenly distributed sliding grooves to facilitate sliding.
[0009] Furthermore, the screening hopper includes ribs, and the rear side of the screening hopper is provided with evenly distributed ribs, all of which are slidably connected to the adjacent sliding grooves on the rear side for easy sliding.
[0010] Furthermore, the screening hopper also includes a retrieval door and a material door. The upper side wall of the screening hopper is hinged with a material door, and the front side wall of the screening hopper is hinged with three retrieval doors, which facilitates the feeding and retrieval of brown corundum.
[0011] Furthermore, the screening hopper also includes an upper screen plate, a middle screen plate, and a lower screen plate, which are respectively arranged inside the screening hopper to facilitate the screening of brown corundum.
[0012] Furthermore, a control switch is provided on the left side of the frame, and the input terminal of the control switch is electrically connected to an external power source for stable control.
[0013] Furthermore, the transfer device is an electric conveyor, which is installed between the left and right inner walls of the frame. The input end of the electric conveyor is electrically connected to the output end of the control switch, and the movable plate is fixedly connected to the front side of the electric conveyor for easy lifting.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This lifting mechanism for brown fused alumina crushing has the following advantages:
[0015] The cooperation between the boss and the top platform allows the screening hopper to slide left and right continuously during the lifting process. Through the cooperation of the left and right sliding of the screening hopper with the upper, middle and lower screen plates, the brown fused alumina inside the screening hopper is shaken, thereby screening the brown fused alumina. After screening, the brown fused alumina has a relatively uniform particle size, which allows it to make more full contact with the crushing parts when entering the crushing equipment, so that the crushing force is applied to the material more evenly, thereby improving the crushing efficiency.

Detailed Implementation
[0023] 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.
[0024] Please see Figure 1-6 This embodiment provides a technical solution: a lifting mechanism for pulverizing brown fused alumina, including a frame 1, a control switch 6 on the left side of the frame 1, the input end of the control switch 6 being electrically connected to an external power source, a transfer device for lifting between the left and right inner walls of the frame 1, a temporary storage bin 5 at the front end of the frame 1, and also includes a shaking mechanism 2.
[0025] Shaking mechanism 2: It includes mounting plate 21, boss 22, movable plate 23, and counter-mounting platform 25. Mounting plates 21 are provided on both the left and right inner walls of the frame 1. Bosses 22 are evenly distributed on the opposite inner sides of the two mounting plates 21. A movable plate 23 is provided between the two mounting plates 21. The movable plate 23 is installed in conjunction with a transfer device, which is an electric conveyor 4. The electric conveyor 4 is installed between the left and right inner walls of the frame 1. The input end of the electric conveyor 4 is electrically connected to the output end of the control switch 6. The movable plate 23 is fixedly connected to the front side of the electric conveyor 4. A screening hopper 3 is slidably connected to the front side of the movable plate 23. Counter-mounting platforms 25 are provided on the front ends of both the left and right sides of the screening hopper 3. The counter-mounting platform 25 is adjacent to the boss in the lateral direction. 22 is configured in a staggered manner (two horizontally adjacent bosses 22 are staggered vertically, the end of the top platform 25 near the horizontally adjacent boss 22 is arc-shaped, and the end of the boss 22 near the top platform 25 is also arc-shaped). The shaking mechanism 2 also includes a slide groove 24. The front side of the moving plate 23 is provided with evenly distributed slide grooves 24. The screening hopper 3 includes ribs 36. The rear side of the screening hopper 3 is provided with evenly distributed ribs 36. All ribs 36 are slidably connected to the adjacent slide grooves 24 on the rear side. The screening hopper 3 also includes a pick-up door 31 and a material door 32 (the pick-up door 31 and the material door 32 are all provided with door locks where they contact the side wall of the screening hopper 3). The upper side wall of the screening hopper 3 is hinged to the material door 32 by a hinge. The front side wall of the screening hopper 3 is hinged to the material door 32 by a hinge. The hinged structure has three access doors 31. The screening hopper 3 also includes an upper screen plate 33, a middle screen plate 34, and a lower screen plate 35. The upper screen plate 33, the middle screen plate 34, and the lower screen plate 35 are respectively installed inside the screening hopper 3 (the screen hole diameter of the upper screen plate 33 is larger than that of the middle screen plate 34, which is larger than that of the lower screen plate 35). After the worker unlocks the upper door lock, the material door 32 is opened, and the brown corundum inside the temporary storage bin 5 is taken out and placed into the screening hopper 3. Then, the material door 32 is closed, and the upper door lock is closed. At this time, the worker operates the control switch 6 to start the electric conveyor 4. The electric conveyor 4 drives the moving plate 23 to start lifting upward, thereby driving the screening hopper 3 to move synchronously. During the upward movement of the screening hopper 3... The opposing platforms 25 on both sides of the screening hopper 3 continuously contact the adjacent protrusions 22. When the right-side opposing platform 25 passes the right-side protrusion 22, it is restricted by the current protrusion 22, and the screening hopper 3 moves to the left. After a period of time, when the left-side opposing platform 25 passes the left-side protrusion 22, it is restricted by the current protrusion 22, and the screening hopper 3 moves to the right. This process repeats. During the lifting process, the screening hopper 3 continuously slides left and right (sliding through the ribs 36 and the sliding grooves 24). At this time, the brown fused alumina inside the screening hopper 3 is subjected to shaking force and is screened by the upper screen plate 33, the middle screen plate 34, and the lower screen plate 35. The smallest particles of brown fused alumina pass through the three screen plates in sequence and fall to the bottom of the screening hopper 3.Brown fused alumina particles larger than the mesh size of the lower sieve plate 35 pass through the upper sieve plate 33 and fall onto the lower sieve plate 35. The remaining brown fused alumina is separated by the upper sieve plate 33, effectively separating particles of different sizes. This results in more uniform particle size of the brown fused alumina entering the next processing stage or as the finished product. Workers then open the three extraction doors 31 to remove brown fused alumina particles of different sizes for subsequent crushing. The sieved brown fused alumina, with its relatively uniform particle size, can make more thorough contact with the crushing components when entering the crushing equipment, allowing the crushing force to act more evenly on the material, thereby improving crushing efficiency.
[0026] The working principle of the lifting mechanism for pulverizing brown fused alumina provided by this utility model is as follows: First, the worker unlocks the upper door lock and opens the material door 32. The brown fused alumina inside the temporary storage bin 5 is taken out and placed into the screening hopper 3. Then, the worker closes the material door 32 and the upper door lock. At this time, the worker operates the control switch 6 to make the electric conveyor 4 run. The electric conveyor 4 drives the moving plate 23 to start lifting upward, thereby driving the screening hopper 3 to move synchronously. During the upward movement of the screening hopper 3, the opposing platforms 25 on both sides of the screening hopper 3 continuously contact the adjacent protrusions 22. When the opposing platform 25 on the right passes the protrusion 22 on the right, it is restricted by the current protrusion 22, and the screening hopper 3 moves to the left. After a period of time, when the opposing platform 25 on the left passes the protrusion 22 on the left, it is restricted by the current protrusion 22. Due to the limitation of 2, the screening hopper 3 moves to the right. This process is repeated. During the lifting process, the screening hopper 3 slides left and right continuously (sliding through the rib 36 in conjunction with the chute 24). At this time, the brown fused alumina inside the screening hopper 3 is subjected to shaking force. Through the screening of the upper screen plate 33, the middle screen plate 34 and the lower screen plate 35, the smallest brown fused alumina particles pass through the three screen plates and fall to the bottom of the screening hopper 3. Brown fused alumina particles larger than the screen hole size of the lower screen plate 35 pass through the upper screen plate 33 and fall onto the lower screen plate 35. The remaining brown fused alumina is separated by the upper screen plate 33, effectively separating the brown fused alumina particles of different sizes, making the brown fused alumina particles entering the next processing stage or the finished product more uniform in size. Then, the workers open the three extraction doors 31 to take out brown fused alumina particles of different sizes for subsequent work.
[0027] It is worth noting that the electric conveyor 4 disclosed in the above embodiments can be model CB-01, and the control switch 6 is provided with a control button corresponding to the electric conveyor 4 and used to control its switching.
