Detailed Implementation

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figures 1-4 As shown, the mineral powder batching device provided in this embodiment includes a pneumatic conveyor 1 and a discharge pipe 2 fixedly installed at the output end of the pneumatic conveyor 1. A conveying pipe 3 is fixedly connected to the end of the discharge pipe 2 away from the pneumatic conveyor 1. A mixing bin 21 is fixedly installed at the upper end of the discharge pipe 2. Transition bins 4 are fixedly installed at the upper and lower ends of the mixing bin 21. A material distribution shaft 5 is rotatably arranged inside the transition bin 4. A storage bin 6 is fixedly connected to the upper end of the transition bin 4. Several evenly distributed mixing piles 7 are fixedly installed inside the mixing bin 21.

[0025] The storage silo 6 is used to store pre-mixed mineral powder. The mineral powder falls into the transition silo 4 by its own gravity, and then falls into the mixing silo 21 in batches by the rotation of the distribution shaft 5. During the falling process, the mineral powder collides with several mixing piles 7, and is then dispersed and evenly gathered at the bottom of the mixing silo 21. Finally, it falls into the discharge pipe 2 and is discharged from the conveying pipe 3 through the pneumatic conveyor 1. It can reduce dust problems and solve noise problems by pneumatic conveying while mixing.

[0026] Furthermore, such as Figures 1-4 As shown, a synchronous motor 8 is fixedly installed at one end of the transition chamber 4. The output end of the synchronous motor 8 extends into the interior of the transition chamber 4. The material distribution shaft 5 is rotatably installed inside the transition chamber 4 via the synchronous motor 8. The synchronous motor 8 is used to drive the rotation of the material distribution shaft 5. Several evenly distributed partitions 511 are fixedly installed on the material distribution shaft 5. The space between two adjacent partitions 51 can be used to temporarily store mineral powder, and the material is discharged through the rotation of the material distribution shaft 5. This allows the feeding and discharging of the mixing chamber 21 to be synchronized and balanced, thus achieving continuous production.

[0027] Furthermore, such as Figure 1 , Figure 2 and Figure 3As shown, the upper end of the mixing silo 21 is connected to the interior of the storage silo 6 through the transition silo 4, and the bottom end of the conveying pipe 3 is connected to the interior of the mixing silo 21 through the transition silo 4. The inner bottom side of the mixing silo 21 is funnel-shaped, and the two adjacent mixing piles 7 are staggered. During the process of material entering the mixing silo 21 from the storage silo 6, dust or material splashing may occur. The transition silo 4 can close this feeding channel through the material distribution shaft 5 and the partition 511 to reduce the intense contact between the material and the outside air, thereby reducing the generation of dust and preventing the material from splashing out of the mixing silo 21, maintaining a clean working environment and effective utilization of materials.

[0028] Meanwhile, the two adjacent mixing piles 7 are staggered. The staggered mixing piles 7 can change the flow path of the material in the mixing bin 21, which can improve the mixing efficiency of the mineral powder. During the conveying process of the pneumatic conveyor 1, the material can be broken up and mixed again, so that the mineral powder is mixed more fully, thereby improving the uniformity of the mineral powder mixing and improving the production quality.

[0029] Furthermore, such as Figure 1 and Figure 3 As shown, a horizontal support 31 is fixedly installed on the conveying pipe 3. The bottom end of the horizontal support 31 is fixedly installed on the ground by bolts. Support frames 9 are fixedly installed on both ends of the bottom side of the discharge pipe 2. Two bow-shaped support ribs 10 are fixedly installed on the support frame 9 by bolts. The bow-shaped support ribs 10 are distributed on both sides of the mixing bin 21. During the process of conveying materials, the conveying pipe 3 may vibrate due to the flow of materials. The horizontal support 31 is fixed to the ground by bolts, which can provide stable support for the conveying pipe 3 and reduce its shaking.

[0030] Meanwhile, the support frame 9, as the main support structure, is fixed to both ends of the bottom side of the feeding pipe 2 with bolts, bearing most of the weight of the feeding pipe 2 and preventing the feeding pipe 2 from sagging or deforming due to its own weight. The bow-shaped bracing ribs 10 are distributed on both sides of the mixing bin 21. They are connected to the support frame 9 and play a reinforcing role. On the one hand, they can prevent the feeding pipe 2 from swinging due to vibration or other external forces during operation, which would affect the structural stability of the mixing bin 21. On the other hand, the bow-shaped bracing ribs 10 can apply a certain supporting force to both sides of the mixing bin 21, enhancing the ability of the mixing bin 21 to resist material impact and deformation caused by its own weight.

[0031] In addition, such as Figure 2 , Figure 3 and Figure 4 As shown, an electromagnet 11 is fixedly installed in the middle of the bow-shaped support rib 10, and several magnetic conductors 12 are fixedly arranged between the two electromagnets 11. The arrangement of the magnetic conductors 12 matches the arrangement of several mixing piles 7. The magnetic conductors 12 penetrate the mixing bin 21 and extend to both sides of the discharge pipe 2.

[0032] Among them, the electromagnet 11 is used to generate magnetism in the magnetic conductor 12. The magnetic conductor 12 passes through the mixing bin 21 and can attract iron screws or other component fragments of the mineral powder, preventing the material distribution shaft 5 and the partition 511 from being jammed by parts falling from the device itself. At the same time, it can also prevent the transition bin 4 and the discharge pipe 2 from being blocked, thereby greatly extending the service life of the mineral powder batching device.

[0033] like Figures 1-4 As shown, the principle of the mineral powder batching device provided in this embodiment is as follows:

[0034] In use, the pre-prepared mineral powder is poured into the storage silo 6 for storage. The synchronous motor 8 is started to drive the distribution shaft 5 and the partition 511 to rotate. The mineral powder falls into the transition silo 4 by its own gravity, and then falls into the mixing silo 21 in batches by the rotation of the distribution shaft 5. During the falling process, the mineral powder collides with several mixing piles 7, and is then dispersed and evenly gathered at the bottom of the mixing silo 21. The electromagnet 11 works to make the magnetic conductor 12 attract iron impurities. The mixed mineral powder falls into the discharge pipe 2 through the transition silo 4 at the bottom of the mixing silo 21. During this period, the distribution shaft 5 and the partition 511 can control the quality of the falling mineral powder again. Finally, the pneumatic conveyor 1 is started to discharge the mineral powder through the conveying pipe 3.
