Description

Technical Field

[0001] This application relates to the field of pneumatic conveying technology, and more specifically, to an intelligent high-precision pneumatic conveying device. Background Technology

[0002] Intelligent high-precision pneumatic conveying devices are equipment that achieve precise material conveying through intelligent technology. They use air as a carrier and utilize the energy of airflow to propel materials through pipes. Through advanced sensors and control systems, parameters such as material flow rate, pressure, and speed during the conveying process are monitored and precisely controlled in real time. They feature high conveying accuracy, strong stability, high degree of automation, and adaptability to various materials and complex working conditions. They can be widely used in multiple industries such as chemical, food, and pharmaceutical, effectively improving production efficiency and quality while reducing labor costs and material losses.

[0003] In traditional pneumatic conveying systems, materials are easily broken upon direct impact with the inner wall of the discharge port, resulting in significant material loss and low yield. The system struggles to fully protect the integrity of the material, a problem particularly pronounced when conveying brittle materials.

[0004] In view of this, this application proposes an intelligent high-precision pneumatic conveying device. Utility Model Content

[0005] The purpose of this application is to provide an intelligent high-precision pneumatic conveying device, which solves the technical problems in the background art and achieves the technical effect of an intelligent high-precision pneumatic conveying device.

[0006] This application provides an intelligent high-precision pneumatic conveying device, including a conveying pipe. One end of the conveying pipe is provided with a discharge mechanism, and the other end of the conveying pipe is provided with a fan. The discharge mechanism includes a discharge frame located at one end of the conveying pipe. A silicone sleeve is fixedly connected to the lower part of the inside of the discharge frame. A soft rubber sheet is fixedly connected to the upper part of one side of the inner wall of the discharge frame. A fixing plate is fixedly connected to the upper part of the inside of the discharge frame. A plurality of staggered spherical grooves are opened on the lower end face of the fixing plate. A spherical block is movably engaged inside the spherical groove. A connecting block is fixedly connected to the lower part of the outer wall of the spherical block. A soft rubber strip is fixedly connected to the lower end of the connecting block.

[0007] Optionally, a feeding pipe is fixedly connected to the upper part of the outer wall of the conveying pipe, and a fixed motor is fixedly connected to the outer wall of the feeding pipe.

[0008] Optionally, a cross-shaped material divider is rotatably connected inside the feeding pipe, and the output end of the fixed motor is fixedly connected to the cross-shaped material divider.

[0009] Optionally, one end of the fan is fixedly connected to a communicating air outlet sleeve, and one end of the air outlet sleeve is sleeved to one end of the conveying pipe. A communicating air inlet pipe is fixedly connected to the lower part of one end of the fan.

[0010] Optionally, a filter screen is fixedly connected inside the air inlet pipe, a rotating rod is rotatably connected through the filter screen, multiple brush strips are fixedly connected to the outer wall of the lower end of the rotating rod, and a fan blade is fixedly connected to the upper end of the rotating rod.

[0011] Optionally, the upper side wall of the discharge frame is fixedly connected to a connecting pipe, and one end of the connecting pipe is sleeved with the other end of the conveying pipe.

[0012] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0013] 1. This application installs a discharge frame at one end of the conveying pipe. After entering the discharge frame, the material impacts multiple staggered soft rubber strips. These strips act as a buffer, preventing the material from directly impacting the inner wall of the discharge frame and breaking. This effectively protects the integrity of the material, reduces material loss, and improves the product yield. Upon impact, the soft rubber strips oscillate, causing the connecting block to oscillate, while the spherical block flips within the spherical groove. This structural design prevents the soft rubber strips from continuously bending and breaking, extending their service life and reducing equipment maintenance costs and the frequency of parts replacement. Materials with greater impact force pass through the soft rubber strips and impact the soft rubber sheet. The discharged material first falls onto a silicone sleeve. The silicone sleeve and soft rubber sheet further reduce the impact force of the falling material, comprehensively protecting the integrity of the material from multiple stages and ensuring that the material is not damaged throughout the entire feeding process.

[0014] 2. This application utilizes a filter installed inside the air inlet duct. This filter effectively removes impurities from the air, preventing them from entering the conveying pipe and material box, thus preventing impurities from mixing with the material and affecting its quality. This ensures the purity of the discharged material. The airflow drives the fan blades to rotate, which in turn drives the rotating rod and brush strips to rotate synchronously. The brush strips continuously agitate impurities on the filter, preventing them from accumulating and clogging the filter. This maintains a consistently good ventilation effect, ensuring the fan provides stable airflow, guaranteeing smooth material conveying, and preventing decreased conveying efficiency or equipment failure due to poor ventilation.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-3 This application provides an intelligent high-precision pneumatic conveying device, including a conveying pipe 1, a discharge mechanism 2 at one end of the conveying pipe 1, and a fan 5 at the other end of the conveying pipe 1. The discharge mechanism 2 includes a discharge frame 201 located at one end of the conveying pipe 1. A silicone sleeve 203 is fixedly connected to the lower part of the discharge frame 201. A soft rubber sheet 204 is fixedly connected to the upper part of one side of the inner wall of the discharge frame 201. A fixing plate 205 is fixedly connected to the upper part of the inner wall of the discharge frame 201. A plurality of staggered spherical grooves 206 are opened on the lower end face of the fixing plate 205. A spherical block 207 is movably engaged inside the spherical groove 206. A connecting block 208 is fixedly connected to the lower part of the outer wall of the spherical block 207. A soft rubber strip 209 is fixedly connected to the lower end of the connecting block 208. After the material enters the discharge frame 201, it will collide with the plurality of staggered soft rubber strips 209. The soft rubber strips 209 play a buffering role to prevent the material from directly impacting the inner wall of the discharge frame 201 and being broken. This design effectively protects the integrity of materials, reduces material loss, and improves product yield. Upon impact, the soft rubber strip 209 swings, causing the connecting block 208 to swing, while the spherical block 207 flips within the spherical groove 206. This structural design prevents the soft rubber strip 209 from continuously bending and breaking, extending its service life and reducing equipment maintenance costs and the frequency of parts replacement. Materials with greater impact force pass through the soft rubber strip 209 and then impact the soft rubber sheet 204. After feeding, the material first falls onto the silicone sleeve 203. The silicone sleeve 203 and the soft rubber sheet 204 further reduce the impact force of the falling material, comprehensively protecting the integrity of the material from multiple stages and ensuring that the material is not damaged throughout the feeding process.

[0021] A feeding pipe 3 is fixedly connected to the upper part of the outer wall of the conveying pipe 1. A fixed motor 4 is fixedly connected to the outer wall of the feeding pipe 3. A cross-shaped material divider 12 is rotatably connected inside the feeding pipe 3. The output end of the fixed motor 4 is fixedly connected to the cross-shaped material divider 12. When the fixed motor 4 is started, it drives the cross-shaped material divider 12 to rotate, and the cross-shaped material divider 12 can continuously and evenly feed the material into the conveying pipe 1. This uniform material distribution method can make the material more evenly distributed during the conveying process, avoid the blockage or accumulation of material in the conveying pipe 1 caused by concentrated material feeding, and improve the stability and efficiency of material conveying. The cross-shaped material divider 12 also acts as a windbreak while distributing the material, preventing strong winds from blowing into the material box. Strong winds entering the material box may disrupt the normal feeding sequence of the material and affect the feeding rate. The windproof design of the cross-shaped material divider 12 ensures that the material can be fed at the predetermined rate and in the predetermined manner, making the feeding process more controllable.

[0022] One end of the blower 5 is fixedly connected to a communicating air outlet sleeve 6, and one end of the air outlet sleeve 6 is fitted into one end of the conveying pipe 1. A communicating air inlet pipe 7 is fixedly connected to the lower end of one end of the blower 5. A filter screen 8 is fixedly connected inside the air inlet pipe 7. A rotating rod 9 is rotatably connected through the filter screen 8. Multiple brush strips 10 are fixedly connected to the outer wall of the lower end of the rotating rod 9. A fan blade 11 is fixedly connected to the upper end of the rotating rod 9. A communicating connecting pipe 202 is fixedly connected to the upper side wall of the discharge frame 201, and one end of the connecting pipe 202 is fitted into the other end of the conveying pipe 1. By installing the filter screen 8 inside the air inlet pipe 7, the filter screen 8 can effectively filter out impurities in the air. This prevents impurities from entering the conveying pipe 1 and the material box with the air, preventing impurities from mixing with the material and affecting the material quality, thus ensuring the purity of the discharged material. The air blows the fan blade 11 to rotate, which in turn drives the rotating rod 9 and the brush strips 10 to rotate synchronously. The brush strips 10 continuously agitate the impurities on the filter screen 8, preventing impurities from accumulating and clogging the filter screen 8. This ensures that good ventilation is maintained, that the fan 5 provides stable airflow, that the material conveying process is smooth, and that the conveying efficiency is reduced or the equipment fails due to poor ventilation.

[0023] Working principle: When in use, the feeding pipe 3 is installed at the discharge port of the material box. When feeding is required, the fan 5 is started first. When the fan 5 is working, air enters the air inlet pipe 7. The filter screen 8 inside the air inlet pipe 7 filters out impurities in the air. At the same time, the air blows the fan blade 11 to rotate. The rotation of the fan blade 11 drives the rotating rod 9 and the brush strip 10 on the rotating rod 9 to rotate synchronously. The rotation of the brush strip 10 will continuously move the impurities on the filter screen 8 to prevent the impurities from clogging the filter screen 8 and affecting the ventilation effect. The filtered air enters the air outlet sleeve 6 from the air inlet pipe 7 and is blown into the conveying pipe 1 from the air outlet sleeve 6.

[0024] Start the fixed motor 4. The fixed motor 4 drives the cross-shaped material divider 12 to rotate. The rotation of the cross-shaped material divider 12 will continuously feed the material into the conveying pipe 1. At the same time, the cross-shaped material divider 12 acts as a windbreak to prevent strong winds from blowing into the material box and affecting the feeding rate. As the material enters the conveying pipe 1, a strong wind blows it into the discharge frame 201. The material impacts multiple staggered soft rubber strips 209, which act as buffers to prevent the material from directly impacting the inner wall of the discharge frame 201 and breaking it. After being impacted, the soft rubber strips 209 swing, which in turn causes the connecting block 208 to swing. At the same time, the spherical block 207 flips within the spherical groove 206, preventing the soft rubber strips 209 from bending and breaking. Material with greater impact force passes through multiple soft rubber strips 209 and finally impacts the soft rubber sheet 204. After being discharged, the material first falls onto the silicone sleeve 203, which reduces the impact force of the falling material, thus providing more comprehensive protection for the integrity of the material.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
