Abstract

Technical Field
[0001] This utility model relates to the field of brown fused alumina processing technology, specifically a brown fused alumina abrasive segment sand device. Background Technology
[0002] In the processing of brown fused alumina, abrasive sand-grinding devices are widely used to treat brown fused alumina with abrasive sand. Brown fused alumina, also known as corundum, is a brownish-red synthetic corundum produced by melting and reducing bauxite, carbon materials, and iron filings in an electric arc furnace, hence its name. Brown fused alumina is the most basic abrasive, widely used due to its good grinding performance, wide range of applications, and low price. Abrasive sand-grinding devices are also used in the processing of brown fused alumina.
[0003] Authorization announcement number CN221492669 U discloses a brown fused alumina abrasive segment sand device, including a crushing chamber, a screening chamber fixedly connected to the bottom of the crushing chamber, a fixing plate fixedly connected to the lower right side of the outer wall of the crushing chamber, a first motor fixedly connected to the bottom of the fixing plate, a second gear fixedly connected to the output end of the first motor, and the rear end of the outer ring of the second gear meshing with the first gear.
[0004] The device screens brown fused alumina particles using an inclined filter screen. However, due to the angle, the brown fused alumina moves faster on the filter screen, causing the brown fused alumina that meets the size requirements to be rushed into the transport chamber and thus undergo repeated processing. To address this, we propose a brown fused alumina abrasive segmentation device. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a brown fused alumina abrasive sectioning device. By using a rotating roller to block the brown fused alumina rolling on the upper right side of the screen, the moving speed of the brown fused alumina is slowed down, the screening accuracy is improved, and the working efficiency is increased. This can effectively solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a brown fused alumina abrasive section grinding device, comprising a storage tank, an upper end of which is connected to a guide hood, a crushing mechanism installed on the lower side of the guide hood, the crushing mechanism being used to crush brown fused alumina, a screen fixedly connected to the internal inclined channel of the storage tank, the screen being used to screen the crushed brown fused alumina, the right side surface of the storage tank, located above the screen, is connected to the left end of a conveying pipe, the right end of the conveying pipe being connected to a conveying mechanism, the conveying mechanism being used to send larger brown fused alumina back to the feed. The material is crushed again. Cams are set on the upper and lower parts of the right side of the screen. A rotating roller is fixedly connected to the middle of the upper rotating rod, and a cam is fixedly connected to the lower rotating rod. The front and rear parts of the two rotating rods are rotatably connected to the inner surface of the storage box one through bearings. The rear ends of the two rotating rods extend to the outside of the storage box one through the round holes opened on the storage box one. Gear three is fixedly connected to the rear end of the upper rotating rod, and gear two is fixedly connected to the rear end of the lower rotating rod. Gear two and gear three mesh. The front end of the upper rotating rod is connected to the power mechanism.
[0007] The design incorporates a rotating roller that, rotating clockwise, blocks the brown fused alumina rolling to the right, slowing its movement, improving screening accuracy, and increasing work efficiency. A cam is also designed to vibrate the screen, reducing brown fused alumina accumulation and improving operational stability. When the control device is operational, the brown fused alumina, after being crushed by the crushing mechanism, falls onto the screen and gradually rolls to the right. At this point, the power mechanism drives the upper rotating rod to rotate clockwise, which in turn drives gear two, causing the cam to vibrate the screen. During this rolling process, appropriately sized brown fused alumina passes through the screen and falls into storage bin one for storage, while larger pieces pass through conveyor pipe one and enter the conveying mechanism, which returns the larger pieces for further crushing.
[0008] Furthermore, the power mechanism includes a motor three, which is fixedly connected to the front surface of the storage box one. The output shaft of the motor three extends through a circular hole in the storage box one into the interior of the storage box one and is fixedly connected to the front end of the upper rotating rod. The input end of the motor three is electrically connected to the output end of an external power supply through an external control switch group.
[0009] When the power mechanism is working, the motor is controlled by an external control switch group, which in turn drives the upper rotating rod to rotate clockwise.
[0010] Furthermore, the crushing mechanism includes crushing rollers. The crushing rollers are arranged laterally at the front and rear parts of the storage tank at the lower side of the guide shroud. The left and right parts of the two crushing rollers are rotatably connected to the inner surface of the storage tank at corresponding positions through bearings. The left ends of the two crushing rollers extend through the circular holes opened on the storage tank to the left side of the storage tank and are respectively fixedly connected to gears. The two gears are meshed. The upper part of the right side surface of the storage tank is fixedly connected to a motor. The output shaft of the motor passes through the circular hole opened on the storage tank and is fixedly connected to the right end of the front crushing roller. The input end of the motor is electrically connected to the output end of an external power supply through an external control switch group.
[0011] When the crushing mechanism is in operation, the motor is controlled by an external control switch group, which in turn drives the two crushing rollers to rotate in opposite directions to perform the crushing work.
[0012] Furthermore, the conveying mechanism includes a storage box two, the right end of the conveying pipe one is connected to the storage box two, the lower middle part of the storage box two is fixedly connected to a motor two, the output shaft of the motor two extends through a circular hole opened on the storage box two to the interior of the storage box two, and is fixedly connected to the lower end of a rotating rod, a feeding screw is fixedly connected to the rotating rod, the upper left side surface of the storage box two is connected to the right end of the conveying pipe two, the left end of the conveying pipe two extends to the upper side of the guide shroud, and the input end of the motor two is electrically connected to the output end of an external power supply through an external control switch group.
[0013] When the control conveying mechanism is working, the external control motor 2 works, which drives the rotating rod to rotate, which in turn drives the feeding screw to rotate, thereby conveying the brown corundum in the storage box 2 upward, and then conveying it to the guide shroud through the conveying pipe 2.

[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 1-5 This embodiment provides a technical solution: a brown fused alumina abrasive section grinding device, including a storage tank 1, with a guide hood 2 connected to the upper end of the storage tank 1. A crushing mechanism is installed on the lower side of the guide hood 2, used to crush brown fused alumina. A screen 6 is fixedly connected to the internal inclined channel of the storage tank 1, used to screen the crushed brown fused alumina. The right side surface of the storage tank 1, located above the screen 6, is connected to the left end of a conveying pipe 7. The right end of the conveying pipe 7 is connected to a conveying mechanism, used to send larger brown fused alumina back for further crushing. The upper and lower parts of the right side of the screen 6 are respectively provided with... A cam 14 is placed on the upper rotating rod 13, and a rotating roller 15 is fixedly connected to the middle of the upper rotating rod 13. The cam 14 is fixedly connected to the lower rotating rod 13. The front and rear parts of the two rotating rods 13 are rotatably connected to the inner surface of the storage box 1 through bearings. The rear ends of the two rotating rods 13 extend through the round holes opened on the storage box 1 to the outside of the storage box 1.

The gear 2 16 meshes with the gear 3 17. The front end of the upper rotating rod 13 is connected to a power mechanism.
[0025] A rotating roller 15 is designed to block the brown fused alumina rolling to the right by rotating clockwise, thus slowing down the movement of the brown fused alumina, improving the accuracy of screening, and increasing work efficiency. A cam 14 is designed to vibrate the screen 6 by rotating, thereby reducing the accumulation of brown fused alumina on the screen 6 and improving work stability. When the control device is working, the brown fused alumina is crushed by the crushing mechanism and falls onto the screen 6, gradually rolling to the right side of the screen 6. At this time, the upper rotating rod 13 is driven to rotate clockwise by the power mechanism, and then the gear 17 drives the gear 16 to rotate, thereby driving the cam 14 to vibrate the screen 6. During the rolling process, brown fused alumina of suitable size passes through the screen 6 and falls into the storage bin 1 for storage, while larger brown fused alumina passes through the conveying pipe 7 and enters the conveying mechanism, which sends the larger brown fused alumina back for further crushing.
[0026] The power mechanism includes a motor 318. The motor 318 is fixedly connected to the front surface of the storage box 1. The output shaft of the motor 318 extends through a circular hole in the storage box 1 to the inside of the storage box 1 and is fixedly connected to the front end of the upper rotating rod 13. The input end of the motor 318 is electrically connected to the output end of the external power supply through an external control switch group.
[0027] When the power control mechanism is working, the motor 18 is controlled by the external control switch group, which drives the upper rotating rod 13 to rotate clockwise.
[0028] The crushing mechanism includes crushing rollers 3. The crushing rollers 3 are arranged horizontally at the front and rear parts of the storage box 1, which is located below the guide shroud 2. The left and right parts of the two crushing rollers 3 are rotatably connected to the inner surface of the storage box 1 through bearings. The left ends of the two crushing rollers 3 extend to the left side of the storage box 1 through the round holes opened on the storage box 1, and are respectively fixedly connected to gears 4. The two gears 4 are meshed. The upper part of the right side surface of the storage box 1 is fixedly connected to a motor 5. The output shaft of the motor 5 passes through the round hole opened on the storage box 1 and is fixedly connected to the right end of the front crushing roller 3. The input end of the motor 5 is electrically connected to the output end of the external power supply through an external control switch group.
[0029] When the crushing mechanism is in operation, the motor 5 is controlled by an external control switch group, which in turn drives the two crushing rollers 3 to rotate in opposite directions to carry out the crushing work.
[0030] The conveying mechanism includes a storage bin 2 8, the right end of the conveying pipe 1 7 is connected to the storage bin 2 8, the lower middle part of the storage bin 2 8 is fixedly connected to the motor 2 9, the output shaft of the motor 2 9 extends through a circular hole opened on the storage bin 2 8 to the inside of the storage bin 2 8, and is fixedly connected to the lower end of the rotating rod 10, the feeding screw 11 is fixedly connected to the rotating rod 10, the upper left side surface of the storage bin 2 8 is connected to the right end of the conveying pipe 2 12, the left end of the conveying pipe 2 12 extends to the upper side of the guide shroud 2, and the input end of the motor 2 9 is electrically connected to the output end of the external power supply through an external control switch group.
[0031] When the control conveying mechanism is working, the external control motor 29 works, which drives the rotating rod 10 to rotate, which in turn drives the feeding screw 11 to rotate, thereby conveying the brown corundum in the storage box 28 upward, and then conveying it to the guide shroud 2 through the conveying pipe 22.
[0032] The working principle of the brown fused alumina abrasive segment sand device provided by this utility model is as follows:
[0033] The external control switch group controls the operation of motor 5, which in turn drives two grinding rollers 3 to rotate in opposite directions to perform grinding. The ground brown fused alumina falls onto the screen 6 and gradually rolls to the right side of the screen 6. The external control switch group then controls motor 18 to operate, which drives the upper rotating rod 13 to rotate clockwise, thereby blocking the brown fused alumina moving to the right and slowing down its movement. Gear 17 drives gear 16 to rotate, which in turn drives cam 14 to vibrate the screen 6. During the rolling process, brown fused alumina of suitable size passes through the screen 6 and falls into storage bin 1 for storage, while larger brown fused alumina passes through conveying pipe 7 and enters storage bin 8. The external control motor 9 operates, which drives rotating rod 10 to rotate, which in turn drives feeding screw 11 to rotate, thereby conveying the brown fused alumina in storage bin 8 upward and then conveying it to guide shroud 2 through conveying pipe 12.
[0034] It is worth noting that in the brown corundum abrasive segment sand device disclosed in the above embodiments, the operation of motor 5, motor 9 and motor 18 is controlled by an external control switch group using a method commonly used in the prior art.
