Description

Technical Field

[0001] The present invention relates to the technical field of powder material conveying, and in particular to a powder material conveying device and method. Background Art

[0002] Powder material conveying devices are equipment used to transport powder materials from one location to another. They mainly include: pneumatic conveying systems, screw conveyors, belt conveyors, vibrating conveyors, bucket elevators and tube chain conveyors. Powder material conveying devices are widely used in many industries. For example, in the chemical industry, powder conveying systems are used to transport various chemicals such as pigments, dyes, catalysts, etc.; in the pharmaceutical industry, powder conveying systems are used to transport pharmaceutical raw materials; in the food processing industry, powder conveying systems are used to transport food raw materials such as flour and powdered sugar.

[0003] Although the pneumatic conveying system in the prior art has the advantages of simple structure, easy operation, flexible pipeline layout, and long conveying distance in the process of conveying powder materials, if the powder materials are affected by the humid environment during storage, a small amount of agglomeration will be generated in the powder materials. If the powder materials are directly put into the pneumatic conveying system for conveying and processing, it is easy to cause blockage at the feed port of the pneumatic conveying system or inside the conveying pipeline, thereby affecting the conveying efficiency of the pneumatic conveying system for powder materials. The pneumatic conveying system still has shortcomings in actual use and needs to be further improved. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a powder material conveying device and method.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A powder material conveying device comprises a conveying pipeline and a feed bin, wherein a feed port is installed on the top of the conveying pipeline, and the bottom end of the feed bin is threadedly connected to the feed port through multiple bolts, a filter plate is arranged inside the feed bin, a crushing mechanism for crushing agglomerated materials is installed on the top of the filter plate, the crushing mechanism comprises a moving plate arranged on the top of the filter plate, a cleaning mechanism for removing a small amount of metal impurities mixed in the powder material is installed on the bottom of the moving plate, and anti-blocking mechanisms for preventing clogging of the powder material are installed on the inner walls on both sides of the feed bin.

[0007] Optionally, both outer walls of the feed bin are provided with slide grooves, and sliders are installed inside the two slide grooves. A first electric telescopic rod is installed on the top of one end of the two sliders away from the slide grooves.

[0008] Optionally, the telescopic ends of the two first electric telescopic rods are both installed with connecting rods, and the bottom ends of the two connecting rods are connected to the top end of the movable plate.

[0009] Optionally, the cleaning mechanism includes multiple connecting blocks installed at the bottom of the movable plate, each of which is adapted to the size of the filter tank inside the filter plate. A driving motor is installed inside the movable plate, and the output end of the driving motor is connected to a mounting seat through one of the connecting blocks.

[0010] Optionally, two rotating plates are rotatably mounted inside the mounting seat, and a plurality of rectangular plates matching the size of the filter tank are mounted at the bottom ends of the two rotating plates.

[0011] Optionally, two second electric telescopic rods are installed inside the multiple rectangular plates, and the telescopic ends of the two second electric telescopic rods are commonly installed with a mounting plate, and an electromagnet is installed on the outer wall of the mounting plate on the side away from the two second electric telescopic rods. Two partitions are rotatably installed between the inner walls on both sides of the feed bin, and the two partitions are rotated to a horizontal state and then abut against the bottom ends of the multiple rectangular plates.

[0012] Optionally, the anti-blocking mechanism includes a driving plate rotatably mounted on the inner walls on both sides of the feed bin, the two driving plates are connected to the inner walls of the feed bin via two springs, and rubber blocks are mounted on the outer walls of the two driving plates on one side close to the springs.

[0013] Optionally, two through grooves compatible with the rubber blocks are provided on the outer walls on both sides of the feed bin, and two storage grooves connected with the through grooves are provided inside the feed bin, and screw rods are rotatably installed inside the two storage grooves, and sealing blocks are threadedly installed on the outer walls of the two screw rods, and one end of the two sealing blocks is compatible with the corresponding through grooves.

[0014] Optionally, third electric telescopic rods are installed on the outer walls on both sides of the feed bin, moving blocks are installed on the telescopic ends of the two third electric telescopic rods, pull ropes are installed on the outer walls of the two moving blocks close to the feed bin, and the ends of the two pull ropes away from the moving blocks are connected to the driving plates close to them.

[0015] Optionally, a powder material conveying method includes the conveying device described above, and the conveying method further includes the following steps:

[0016] Step 1: Connect one end of the conveying pipeline to the preset Roots blower, and then connect the other end of the conveying pipeline to the preset collecting container, then place the powder material to be conveyed inside the feed bin, enter the feed port from the discharge port at the bottom of the feed bin, and enter the conveying pipeline. The wind force discharged by the Roots blower will pneumatically convey the powder material entering the conveying pipeline;

[0017] Step 2: If there is a small amount of agglomerates in the powder material to be transported, when the powder material enters the feed bin, the agglomerates mixed in the powder material are automatically filtered by means of the filter plate, and then the two sliders are controlled to move back and forth inside the corresponding chute, driving the two first electric telescopic rods, the connecting rod and the moving plate to move synchronously, so that the moving plate automatically squeezes and crushes the agglomerates temporarily stored on the top of the filter plate during the movement;

[0018] Step 3: If the powder material to be transported contains a small amount of metal impurities, before the conveying pipeline transports such powder material, first control the two partitions inside the feed bin to rotate upward together to a horizontal state. At this time, the powder material entering the feed bin will be temporarily stored inside the feed bin, and control multiple electromagnets to be energized to generate magnetic force. With the help of a driving motor, drive multiple rectangular plates and electromagnets to rotate together on the top of the two partitions, and a small amount of metal impurities mixed in the powder material are automatically adsorbed and collected by multiple electromagnets with magnetic force;

[0019] Step 4: If it is necessary to transport some powder materials with high viscosity, repeat the above steps for processing powder materials containing a small amount of metal impurities, so that the powder materials entering the feed bin are accumulated on the top of the two partitions, and the preset electric heating blocks inside the two partitions are controlled to start, so that the two partitions heat the powder materials accumulated on the top;

[0020] Step 5: After the powder material with high viscosity is heated, the telescopic ends of the two third electric telescopic rods are controlled to retract and return to their original positions, so that the two drive plates are reset with the help of the elastic reset of the two springs. While the driving motor drives the multiple rectangular plates to rotate, the rectangular plates push the ends of the two drive plates away from the rotating parts. After the rectangular plates rotate to a position away from the drive plates, the drive plates drive the rubber blocks with the help of the two springs to collide with the corresponding blocking blocks, so that the entire feed bin vibrates together, reducing the probability of blockage of sticky powder materials during transportation.

[0021] The beneficial effects of the present invention are:

[0022] 1. In the present invention, if there are a small amount of lumps in the powder material to be transported, the lumps can be automatically filtered out by means of a filter plate when the powder material enters the feed bin, and then the lumps can be squeezed and crushed by means of a crushing mechanism, thereby reducing the probability of blockage in the conveying pipeline and facilitating the rapid conveying of the powder material containing lumps by the entire device.

[0023] 2. In the present invention, if a small amount of metal impurities are mixed in the powder material to be transported, before the conveying pipeline transports such powder material, the two partitions inside the feed bin can be controlled to rotate upward together to be horizontal, so that they are spliced ​​together to block the discharge port at the bottom of the feed bin. At this time, the powder material entering the feed bin will fall on the top of the two partitions after passing through the filter plate, and will be temporarily stored inside the feed bin. Through the cooperation of multiple components of the cleaning mechanism, the small amount of metal impurities mixed in the powder material can be automatically adsorbed and collected by multiple electromagnets with magnetic force during the movement and rotation of the multiple rectangular plates, thereby achieving the effect of automatically removing the small amount of metal impurities mixed in the powder material.

[0024] 3. In the present invention, if it is necessary to transport some powder materials with high viscosity, the preset electric heating blocks or electric heating wires inside the two partitions are controlled to be energized and started, so that the heat generated by the two partitions can heat the powder materials piled on the top thereof, and in the process of heating the powder materials, the steps of rotating and moving back and forth inside the feed bin of multiple rectangular plates can also be controlled, so that the powder materials can be dispersed and stirred, the heating efficiency of the powder materials can be improved, and it can be ensured that the powder materials with high viscosity can also be transported quickly and stably inside the conveying pipeline, thereby reducing the difficulty of the device in transporting the powder materials with high viscosity.

[0025] 4. In the invention, after the device completes the conveying work of the powder material, the two rotating plates are controlled to rotate upward together inside the mounting seat to be in a horizontal state, driving the multiple rectangular plates to seal the multiple filter slots inside the filter plate, and then the telescopic ends of the two first electric telescopic rods are controlled to extend upward together, driving the movable plate, the filter plate and other multiple components to move upward to the top of the feed bin. At this time, the filter plate with multiple filter slots blocked by multiple rectangular plates can be used as a cover plate of the feed bin to seal the top opening of the feed bin, thereby preventing foreign matter from easily entering the feed bin from the opening when the device is not in use.

The outer walls of the two driving plates 12 on one side close to the spring 13 are installed with rubber blocks 14.

[0046] As a technical optimization solution of the present invention, two through grooves 6 are provided on the outer walls of both sides of the feed bin 3, which are adapted to the rubber block 14.

After the thrust on the driving plate 12 is released, the two springs 13 are elastically reset, and the rubber block 14 can be driven to quickly collide with the blocking block 17, thereby driving the entire feed bin 3 to vibrate, thereby preventing the powder material from being blocked when entering the feed port 2; and after the two blocking blocks 17 are contracted inside the corresponding receiving grooves 15, the driving plate 12 can drive the rubber The block 14 extends through the through groove 6 and extends out from the inside of the receiving groove 15 along with the blocking block 17, which has abutment and limiting effect on the rubber block 14 inside the through groove 6; two first driving devices are preset inside the feed bin 3, and the output ends of the two first driving devices are respectively connected to one end of the two screw rods 16, which can drive the two screw rods 16 to rotate inside the corresponding receiving groove 15, and drive the corresponding blocking block 17 to move from the inside of the receiving groove 15 to the inside of the through groove 6, thereby having a blocking effect on the through groove 6.

[0047] As a technical optimization solution of the present invention, third electric telescopic rods 18 are installed on both sides of the outer wall of the feed bin 3, and moving blocks 19 are installed at the telescopic ends of the two third electric telescopic rods 18. Pull ropes 20 are installed on the outer wall of the two moving blocks 19 close to the feed bin 3, and the ends of the two pull ropes 20 away from the moving blocks 19 are connected to the driving plate 12 close to them. When the telescopic end of the third electric telescopic rod 18 is extended, it can push the moving block 19 to move in the direction away from the feed bin 3, drive the pull rope 20 to pull the corresponding driving plate 12 to rotate and contract in the direction close to the inner wall of the feed bin 3, so that the driving plate 12 of the anti-blocking mechanism is in an inoperative state.

[0048] As a technical optimization solution of the present invention, a powder material conveying method includes the conveying device mentioned above, and the conveying method also includes the following steps:

[0049] Step 1: Connect one end of the conveying pipeline 1 to the preset Roots blower, and then connect the other end of the conveying pipeline 1 to the preset collecting container, then place the powder material to be conveyed inside the feed bin 3, enter the inside of the feed port 2 from the discharge port at the bottom of the feed bin 3, and enter the inside of the conveying pipeline 1, and the wind force discharged by the Roots blower will pneumatically convey the powder material entering the conveying pipeline 1;

[0050] Step 2: If there is a small amount of agglomerates in the powder material to be transported, when the powder material enters the feed bin 3, the agglomerates mixed in the powder material are automatically filtered by means of the filter plate 7, and then the two sliders 21 are controlled to move back and forth in the corresponding chute 5, driving the two first electric telescopic rods 22, the connecting rod 23 and the moving plate 8 to move synchronously, so that the moving plate 8 automatically squeezes and crushes the agglomerates temporarily stored on the top of the filter plate 7 during the movement;

[0051] Step 3: If a small amount of metal impurities are mixed in the powder material to be transported, before the conveying pipeline 1 transports such powder material, first control the two partitions 11 inside the feed bin 3 to rotate upward together to be in a horizontal state. At this time, the powder material entering the feed bin 3 will be temporarily stored inside the feed bin 3, and control the multiple electromagnets 10 to be energized to generate magnetic force. With the help of the driving motor 25, the multiple rectangular plates 9 and the electromagnets 10 are driven to rotate together on the top of the two partitions 11, and the small amount of metal impurities mixed in the powder material are automatically adsorbed and collected by the multiple electromagnets 10 with magnetic force;

[0052] Step 4: If it is necessary to transport some powder materials with high viscosity, repeat the above steps for processing powder materials containing a small amount of metal impurities, so that the powder materials entering the feed bin 3 are accumulated on the top of the two partitions 11, and the preset electric heating blocks in the two partitions 11 are controlled to start, so that the two partitions 11 heat the powder materials accumulated on the top;

[0053] Step 5: After the powder material with high viscosity is heated, the telescopic ends of the two third electric telescopic rods 18 are controlled to retract and return to their original positions, so that the two drive plates 12 are reset with the help of the elastic reset of the two springs 13. While the driving motor 25 drives the multiple rectangular plates 9 to rotate, the rectangular plates 9 push the ends of the two drive plates 12 away from the rotating parts. After the rectangular plates 9 rotate to a position away from the drive plates 12, the drive plates 12 drive the rubber blocks 14 with the help of the two springs 13 to collide with the corresponding blocking blocks 17, so that the entire feed bin 3 vibrates together, thereby reducing the probability of blockage of the sticky powder material during transportation.

[0054] In the present invention, when the user uses the device, one end of the conveying pipe 1 is connected to the output end of the external preset Roots blower, and then the other end of the conveying pipe 1 is connected to the preset collection container. At this time, the powder material to be conveyed can be placed inside the feed bin 3. After the powder material passes through the filter plate 7, it can enter the inside of the feed port 2 from the discharge port at the bottom of the feed bin 3, and then enter the inside of the conveying pipe 1. The wind force discharged by the Roots blower will pneumatically convey the powder material entering the conveying pipe 1 until the powder material is conveyed through the conveying pipe 1 and discharged into the preset collection container, and the conveying work of the powder material can be completed.

[0055] If there is a small amount of agglomerates in the powder material to be transported, in order to prevent these agglomerates from directly entering the interior of the conveying pipe 1 for transportation, which makes the conveying pipe 1 prone to blockage, when the powder material enters the interior of the feed bin 3, the agglomerates mixed in the powder material can be automatically filtered with the help of the filter plate 7, and the agglomerates are temporarily stored on the top of the filter plate 7. Then, the two sliders 21 can be controlled to move back and forth in the corresponding chute 5 to drive the two first electric telescopic rods 22, the connecting rod 23 and the moving plate 8 to move back and forth synchronously, so that the moving plate 8 can automatically squeeze and crush the agglomerates temporarily stored on the top of the filter plate 7 during the process of moving back and forth on the top of the filter plate 7, so that the crushed agglomerates can pass through the filter plate 7 downward and enter the interior of the conveying pipe 1 for transportation together with the subsequent powder material, thereby reducing the probability of blockage in the conveying pipe 1 and facilitating the rapid transportation of the powder material containing agglomerates by the device as a whole.

[0056] Furthermore, if the powder material to be transported is mixed with a small amount of metal impurities, in order to prevent these metal impurities from entering the interior of the conveying pipe 1 and causing wear on the inner wall of the conveying pipe 1 during the rapid movement, thereby reducing the service life of the conveying pipe 1, before the conveying pipe 1 transports such powder materials, the two partitions 11 inside the feed bin 3 can be controlled to rotate upward together to a horizontal state, so that they are spliced ​​together to block the discharge port at the bottom of the feed bin 3. At this time, the powder material entering the feed bin 3 will fall on the top of the two partitions 11 after passing through the filter plate 7, and will be temporarily stored inside the feed bin 3. Then, the multiple electromagnets 10 are controlled to be powered on to generate magnetic force, and the driving motor 25 is used to drive the mounting seat 26 and the two rotating plates 27 to rotate slowly synchronously, driving the multiple rectangular plates 9 and the electromagnets 10 to rotate together on the top of the two partitions 11, so that the multiple electromagnets 10 can contact the powder material during the rotation process. The two screw rods 16 can also be controlled to rotate to drive the two blocking blocks 17 is stored in the inside of the storage groove 15, so that the two through grooves 6 are exposed, and the telescopic ends of the two third electric telescopic rods 18 are controlled to extend together, driving the two moving blocks 19 to move in the direction away from the feeding bin 3, so that the two moving blocks 19 can respectively pull the two pull ropes 20 to pull the two driving plates 12, and drive the two rubber blocks 14 to pass through the corresponding through grooves 6 respectively, so that the two driving plates 12 are rotated to a state parallel to the inner wall of one side of the feeding bin 3. At this time, the two sliders 21 can be used to move back and forth in the corresponding slide groove 5, and the moving plate 8 can be driven to move on the top of the filter plate 7. At the same time, the mounting seat 26 and the multiple rectangular plates 9 can also be driven to move back and forth synchronously at the bottom of the filter plate 7, so that the multiple electromagnets 10 can be more fully in contact with the powder material. A small amount of metal impurities mixed in the powder material can be automatically adsorbed and collected by the multiple electromagnets 10 with magnetic force during the movement and rotation of the multiple rectangular plates 9, so as to achieve the effect of automatically removing a small amount of metal impurities mixed in the powder material.

[0057] After the multiple electromagnets 10 adsorb and collect a small amount of metal impurities in the powder material, the two partitions 11 are controlled to rotate downward and reset, so that the processed powder material can enter the interior of the conveying pipe 1 through the feed port 2 for transportation, and then the telescopic ends of the two first electric telescopic rods 22 are controlled to extend upward together, driving the two connecting rods 23, the movable plate 8, the filter plate 7 and the mounting seat 26 to move upward together inside the feed bin 3, until the height of the multiple rectangular plates 9 is higher than the height of the two driving plates 12, and then the two rotating plates 27 are controlled to rotate upward together inside the mounting seat 26 to be horizontal, driving the multiple rectangular plates 9 to be inserted into the corresponding filter slots together, and controlling the telescopic ends of the two second electric telescopic rods 28 inside the multiple rectangular plates 9 to extend upward together, driving the corresponding electromagnets 10 to pass upward through the pair The corresponding filter trough is moved to the top of the filter plate 7, and then the telescopic ends of the two first electric telescopic rods 22 are continued to be controlled to extend upward until the multiple rectangular plates 9 are moved to the outside of the feed bin 3. After the multiple electromagnets 10 are powered off and lose their magnetism, the metal impurities magnetically absorbed and collected on the surfaces of the multiple electromagnets 10 fall downward on the top of the filter plate 7. The multiple filter troughs are blocked at their bottom ends with the help of the multiple rectangular plates 9, so that the metal impurities that fall into the filter trough will not fall into the feed bin 3 again. Then, the metal impurities on the top of the filter plate 7 and inside the filter trough can be cleaned by a manual handheld vacuum cleaner or other magnetic equipment, thereby achieving the effect of quickly collecting and removing a small amount of metal impurities in the powder material, and avoiding the adverse effects of metal impurities in the powder material transportation process.

[0058] At the same time, if it is necessary to transport some powder materials with high viscosity, in order to reduce the difficulty of transporting such powder materials, the above-mentioned steps for processing powder materials containing a small amount of metal impurities can be repeated, so that the powder materials entering the feed bin 3 are accumulated on the top of the two partitions 11. At this time, the preset electric heating blocks or heating wires inside the two partitions 11 can be controlled to be energized and started, so that the heat generated by the two partitions 11 can heat the powder materials accumulated on the top, and in the process of heating the powder materials, the above-mentioned steps of rotating and moving back and forth of multiple rectangular plates 9 inside the feed bin 3 can also be repeated, so that it can disperse and stir the powder materials, improve the heating efficiency of the powder materials, ensure that the powder materials with high viscosity can also be quickly and stably transported inside the conveying pipe 1, and reduce the difficulty of the device to transport the powder materials with high viscosity.

[0059] After the powder material with high viscosity is heated, the two partitions 11 are controlled to rotate slowly downward so that the powder material can enter the interior of the conveying pipe 1 downward. At this time, the telescopic ends of the two third electric telescopic rods 18 can be controlled to retract and return to their original positions, so that the two drive plates 12 can be reset with the help of the elastic reset of the two springs 13. The driving motor 25 drives the mounting seat 26, the rotating plate 27 and the plurality of rectangular plates 9 to rotate synchronously, so that the rectangular plates 9 can push the ends of the two drive plates 12 away from the rotating part while rotating clockwise, driving the two pairs of The corresponding springs 13 are in a stretched state. After the rectangular plate 9 rotates to a position away from the driving plate 12, the driving plate 12 loses its thrust and is reset with the help of the elasticity of the two springs 13, driving the rubber block 14 to collide with the corresponding blocking block 17, so that the entire feed bin 3 vibrates together. As the two rubber blocks 14 continue to collide with the blocking block 17, and multiple rectangular plates 9 continue to rotate inside the feed bin 3, the probability of viscous powder materials being blocked during the downward transportation of the feed bin 3 can be reduced, thereby further improving the transportation efficiency of the powder materials.

[0060] Even more, when two or more powder materials need to be mixed and then transported, the feed bin 3 can be used as a stirring and mixing container. After controlling the two partitions 11 to rotate to a horizontal state, two or more powder materials are put into the feed bin 3, and the above-mentioned steps of rotating and moving the multiple rectangular plates 9 back and forth inside the feed bin 3 are repeated. The two or more powder materials can be automatically mixed and stirred before transportation, and there is no need to use additional mixing and stirring equipment to mix them first and then transport the powder materials. Therefore, the device can effectively improve the transportation efficiency when transporting two or more powder materials together.

[0061] After the device is about to complete the conveying work of the powder material, there is no subsequent powder material to be added to the inside of the feed bin 3, and the Roots motor located at one end of the conveying pipe 1 is still in the on state, and the drive motor 25 can continue to be controlled to drive the mounting seat 26 and the multiple rectangular plates 9 thereunder to rotate inside the feed bin 3, so that it can continuously push the two drive plates 12, drive the two rubber blocks 14 to continuously cooperate with the corresponding blocking blocks 17, and clean and remove a small amount of powder material attached to the inner wall of the feed bin 3 by vibration, and continue to convey the cleaned powder material through the conveying pipe 1 to a preset collection container for storage, thereby reducing the loss and waste of powder material during the conveying process.

[0062] After the device completes the conveying work of the powder material and cleans the feed bin 3 and other related components, the two rotating plates 27 can be controlled to rotate upward together inside the mounting seat 26 to be horizontal, driving the multiple rectangular plates 9 to seal the multiple filter slots inside the filter plate 7, and then the telescopic ends of the two first electric telescopic rods 22 are controlled to extend upward together, driving the movable plate 8 and the filter plate 7 and other multiple components to move upward to the top of the feed bin 3. At this time, the filter plate 7 with multiple filter slots blocked by multiple rectangular plates 9 can be used as a cover plate of the feed bin 3 to seal the top opening of the feed bin 3, so as to avoid the problem that foreign matter can easily enter the feed bin 3 from the opening when the device is not in use.

At this time, the powder material entering the feed bin (3) will be temporarily stored inside the feed bin (3). The multiple electromagnets (10) are controlled to be energized to generate magnetic force. With the help of the driving motor (25), the multiple rectangular plates (9) and the electromagnets (10) are driven to rotate together on the top of the two partitions (11). The small amount of metal impurities mixed in the powder material are automatically adsorbed and collected by the multiple electromagnets (10) with magnetic force; Step 4: If it is necessary to transport some powder materials with high viscosity, repeat the above steps for processing powder materials containing a small amount of metal impurities, so that the powder materials entering the feed bin (3) are accumulated on the top of the two partitions (11), and the preset electric heating blocks inside the two partitions (11) are controlled to start, so that the two partitions (11) heat the powder materials accumulated on the top; Step 5: After the powder material with high viscosity is heated, the telescopic ends of the two third electric telescopic rods (18) are controlled to retract and return to their original positions, so that the two drive plates (12) are reset with the help of the elastic reset of the two springs (13). While the driving motor (25) drives the plurality of rectangular plates (9) to rotate, the rectangular plates (9) push the ends of the two drive plates (12) away from the rotating parts. After the rectangular plates (9) rotate to a position away from the drive plates (12), the drive plates (12) drive the rubber blocks (14) with the help of the two springs (13) to collide with the corresponding blocking blocks (17), so that the entire feed bin (3) vibrates together, thereby reducing the probability of blockage of the viscous powder material during transportation.
