Description

TECHNICAL FIELD

[0001] The utility model relates to white corundum abrasive grading technical field, especially in white corundum abrasive fine grading equipment. BACKGROUND

[0002] White corundum abrasive has a wide range of applications in many industrial fields, such as mechanical processing, optical instrument manufacturing, electronic equipment manufacturing, etc. due to its high hardness, good wear resistance, strong chemical stability and other advantages. In these applications, there are strict requirements for the particle size distribution of the abrasive. Different particle sizes of white corundum abrasive are suitable for different processing techniques and product requirements. Among them, white corundum abrasive fine grading equipment is needed.

[0003] At present, the existing white corundum abrasive fine grading equipment mostly uses the following technologies to achieve its effect.

[0004] Gravity settling technology: the gravity settling type classifier realizes grading by using gravity settling technology. Based on Stokes' law, white corundum abrasive particles settle under the action of gravity in a static or slowly flowing liquid medium. Because particles of different sizes have different settling speeds, large particles settle quickly and small particles settle slowly. By controlling the settling time and liquid depth, particles of different sizes can be settled at different positions, thereby achieving grading.

[0005] Centrifugal separation technology: the centrifugal classifier uses centrifugal separation technology. When the equipment is running, the motor drives the drum to rotate at high speed. White corundum abrasive is subjected to centrifugal force in the drum. The centrifugal force is related to the mass of the particle, the rotation speed and the radius of rotation. Large particles are subjected to a large centrifugal force and are thrown to the outside of the drum. Small particles have a small centrifugal force and are close to the center of the drum.

[0006] Airflow classification technology: the airflow classifier uses airflow classification technology. Inside the equipment, high-speed airflow carries white corundum abrasive particles. By setting specific flow channels, classification wheels and guide vanes, a specific airflow field is formed. In the airflow field, particles are subjected to various forces such as airflow drag force and centrifugal force. According to the differences in the motion trajectories of particles in different force fields, large particles are difficult to follow the airflow due to their large inertia and are separated to the outside coarse particle collection area. Small particles enter the inside fine particle collection area with the airflow, achieving grading.

[0007] At present, the existing fine grading equipment using centrifugal separation technology has at least the following problems in actual use.

[0008] The existing fine grading equipment mostly needs to use multiple pipelines to guide the abrasive to different containers for separate storage of particles of different sizes. The use of multiple pipelines not only consumes more raw materials, but also increases the complexity, making it difficult to produce and increasing the production cost. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a fine grading device for white corundum abrasive, solving the problems of existing devices being difficult to manufacture and having high production costs.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A fine grading device for white fused alumina abrasive includes a chassis with four support legs fixedly connected to the bottom. Four slots are formed on the top surface of the chassis. A collection mechanism is connected to the chassis. A mounting frame is connected to the top of the chassis, and a support frame is fixedly connected to the top of the mounting frame. A discharge hopper is fixedly connected to the end of the support frame away from the mounting frame. A solenoid valve is fixedly connected to the discharge port of the discharge hopper. A centrifugal mechanism for separating white fused alumina abrasive is installed on the mounting frame. The collection mechanism includes a collection container, four discharge ports, and a sealing valve. The centrifugal mechanism includes a centrifugal chamber, a gear ring, a motor, and a drive gear.

[0012] Preferably, the collection container is fixedly installed on the top surface of the chassis, and the collection container includes four cylindrical structures, with four discharge ports fixedly connected to the bottom of the chassis.

[0013] Preferably, the four discharge ports are connected to the four cylindrical structures of the collection container, and the four sealing valves are fixedly installed in the middle section of the four discharge ports.

[0014] Preferably, the mounting bracket includes a ring bearing and four support rods, with the four support rods respectively engaging with four slots.

[0015] Preferably, a control panel is fixedly connected to one side of the mounting bracket, and the motor is fixedly connected to the other side of the mounting bracket.

[0016] Preferably, the output end of the motor is fixedly connected to the drive gear, the centrifuge chamber is fixedly connected to the inner side of the ring bearing of the mounting frame, and the gear ring is fixedly connected to the opening end of the centrifuge chamber.

[0017] Preferably, the inner bottom surface of the centrifuge chamber is funnel-shaped, the gear ring meshes with the drive gear, and four sets of screening holes are radially opened at the bottom of the centrifuge chamber. The diameter of each set of screening holes increases in a stepped manner as it moves outward. The number of screening holes in each set is the same as the number of support legs. Four annular grooves are opened on the bottom surface of the centrifuge chamber.

[0018] Preferably, the four annular grooves are respectively connected to the cylindrical structures of the four collection containers, and the four sets of screening holes are respectively facing the opening ends of the four cylindrical structures.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] I. This application, by setting up a collection container, pours abrasive into the inner side of the discharge hopper. The motor is started via the control panel, the motor drives the drive gear to rotate, the drive gear drives the gear ring to rotate, and finally drives the centrifuge chamber to rotate. Subsequently, the control panel activates the solenoid valve to the open state, and the abrasive flows out from the opening end of the discharge hopper and is poured into the inner side of the centrifuge chamber. The abrasive poured into the centrifuge chamber is thrown out due to the centrifugal phenomenon caused by the continuous rotation of the centrifuge chamber. Finally, it falls into the various cylindrical structures of the collection container through different annular grooves, realizing classification. This eliminates the need for traditional guide pipes, making this application easy to produce and solving the problems of existing devices being difficult to produce and having high production costs.

[0021] Second, this application, by incorporating a motor, can adjust the speed of the centrifuge chamber by regulating the motor's speed. In the process of classifying abrasives, the speed of the centrifuge chamber is required to be relatively high. If the speed is too high, the abrasive may accumulate at the edge of the centrifuge chamber, and if the speed is too low, the abrasive may accumulate at the center of the centrifuge chamber. Motor speed regulation is a very mature technology, which enables this application to have a high separation precision. Attached Figure Description

[0029] This application provides a fine grading device for white fused alumina abrasive, which effectively solves the problems of existing devices being difficult to produce and having high production costs.

[0030] Example

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problems of existing devices being difficult to manufacture and having high production costs. The overall idea is as follows:

[0032] To address the problems existing in the prior art, this utility model provides a fine grading device for white fused alumina abrasive, including a chassis 1. Four support legs 102 are fixedly connected to the bottom of the chassis 1. Four slots 101 are opened on the top surface of the chassis 1. A collection mechanism is connected to the chassis 1. A mounting frame 2 is connected to the top of the chassis 1. A support frame 201 is fixedly connected to the top of the mounting frame 2. A discharge hopper 202 is fixedly connected to the end of the support frame 201 away from the mounting frame 2. A solenoid valve 203 is fixedly connected to the discharge port of the discharge hopper 202. A centrifugal mechanism for separating white fused alumina abrasive is installed on the mounting frame 2. The collection mechanism includes a collection container 103, four discharge ports 104 and a sealing valve 105. The centrifugal mechanism includes a centrifugal chamber 3, a gear ring 301, a motor 302 and a drive gear 303.

[0033] The collection container 103 is fixedly installed on the top surface of the chassis 1. The collection container 103 includes four cylindrical structures, and the four discharge ports 104 are all fixedly connected to the bottom of the chassis 1.

[0034] The four discharge ports 104 are respectively connected to the four cylindrical structures of the collection container 103, and the four sealing valves 105 are respectively fixedly installed in the middle section of the four discharge ports 104.

[0035] Mounting bracket 2 includes a ring bearing and four support rods, with the four support rods of mounting bracket 2 respectively docking with four slots 101.

[0036] A control panel 204 is fixedly connected to one side of the mounting bracket 2, and a motor 302 is fixedly connected to the other side of the mounting bracket 2.

[0037] The output end of the motor 302 is fixedly connected to the drive gear 303, the centrifuge chamber 3 is fixedly connected to the inner side of the ring bearing of the mounting frame 2, and the gear ring 301 is fixedly connected to the opening end of the centrifuge chamber 3.

[0038] The inner bottom surface of the centrifuge chamber 3 is funnel-shaped, and the gear ring 301 meshes with the drive gear 303. The bottom of the centrifuge chamber 3 has four sets of screening holes 304 arranged radially. The diameter of each set of screening holes 304 increases stepwise as it moves outward. Each set of screening holes 304 has 102 support legs. The bottom surface of the centrifuge chamber 3 has four annular grooves 305.

[0039] The four annular grooves 305 are respectively connected to the cylindrical structures of the four collection containers 103, and the four sets of sieve holes 304 are respectively facing the opening ends of the four cylindrical structures.

[0040] The chassis 1 is the basic support structure of the entire equipment, providing the installation base for other components. The four support legs 102 at the bottom play the role of stabilizing and supporting the equipment, so that the equipment remains stable during operation. The four slots 101 on the top surface are used to connect with the four support rods of the mounting frame 2 to achieve a fixed connection between the mounting frame 2 and the chassis 1.

[0041] The mounting frame 2 connects to the slots 101 of the chassis 1 via four support rods, mounting components such as the centrifuge chamber 3 on top of the chassis 1. The support frame 201 on top is used to fix the discharge hopper 202, so that the discharge hopper 202 is in a suitable position to facilitate the entry of abrasive into the centrifuge chamber 3. The control panel 204 on one side of the mounting frame 2 is used to control the working status of the motor 302 and the solenoid valve 203 to realize the automated operation of the equipment.

[0042] The centrifuge chamber 3 is the core component for centrifugal classification of abrasives. The gear ring 301 is fixed at the open end of the centrifuge chamber 3 and meshes with the drive gear 303 at the output end of the motor 302. When the motor 302 rotates, it drives the gear ring 301 through the drive gear 303, thereby causing the centrifuge chamber 3 to rotate. The bottom surface of the centrifuge chamber 3 is set in a funnel shape, which helps the abrasives to be thrown out in all directions under the action of centrifugal force. Four sets of screening holes 304 are opened radially at the bottom, and the diameter of the holes increases stepwise towards the outer side. Abrasives of different particle sizes are thrown out through the screening holes 304 of different diameters under the action of centrifugal force. The four annular grooves 305 opened on the bottom surface are respectively connected to the four cylindrical structures of the collection container 103, so that the thrown abrasives can accurately fall into the corresponding cylindrical structures of the collection container 103.

[0043] Working principle:

[0044] The abrasive is poured into the inside of the discharge hopper 202. The motor 302 is started via the control panel 204. The motor 302 drives the drive gear 303 to rotate, which in turn drives the gear ring 301 to rotate, ultimately causing the centrifuge chamber 3 to rotate. Then, the control panel 204 activates the solenoid valve 203 to open, and the abrasive flows out from the opening of the discharge hopper 202 and into the inside of the centrifuge chamber 3. The abrasive poured into the centrifuge chamber 3 is thrown out due to centrifugal force caused by the continuous rotation of the centrifuge chamber 3. Finally, it falls into the various cylindrical structures of the collection container 103 through different annular grooves 305, thus achieving grading.

[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
