Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, and in particular to a large powder conveying device for material tanks. Background Technology

[0002] In the field of large-scale powder conveying, traditional equipment often faces the problem of powder accumulation at the bottom of the tank and poor conveying.

[0003] In existing technologies, the connection between the material tank and the conveying pipe lacks an effective material-discharging structure. Powder is easily compacted by gravity, forming clumps and causing blockages in the discharge pipe. Especially when conveying powders with high moisture content or uneven particle size, relying solely on gravity flow cannot guarantee continuous feeding, requiring frequent shutdowns for cleaning and severely impacting conveying efficiency. Furthermore, the spiral conveyor paddle inside the conveying pipe can only push in one direction, failing to effectively clean residual powder adhering to the pipe wall. Long-term use leads to material waste, and the hardened residual powder, when damp, further exacerbates equipment wear.

[0004] Therefore, it is necessary to provide large-scale powder conveying devices to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a large-scale powder conveying device for material tanks, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a large-scale powder conveying device for a material tank, comprising a material tank body, a discharge pipe installed through the bottom end of the material tank body, the discharge pipe being connected to the interior of the material tank body as a channel for powder to fall from the material tank body, and the through structure of the two ensuring that the powder can smoothly enter the discharge pipe; a conveying pipe is installed through the bottom end of the discharge pipe, the conveying pipe being arranged horizontally to receive the powder falling from the discharge pipe, and the through connection between the discharge pipe and the conveying pipe realizing the transition from vertical to horizontal conveying of the powder; a drive motor is installed at one end of the conveying pipe, the drive motor being fixed on the outside of the end of the conveying pipe, providing a power source for the device; a spiral conveying paddle is connected to the output end of the drive motor through the surface of the conveying pipe, the spiral conveying paddle being located inside the conveying pipe, and its paddle shaft being connected to the drive motor. The output end of the drive motor is coaxially fixed, allowing the drive motor to directly drive the spiral conveyor paddle to rotate inside the conveying pipe, thereby moving the powder. A fixed rod is installed on the circumferential side of the spiral conveyor paddle shaft, and a dispensing plate is installed at one end of the fixed rod. The dispensing plate is close to the inner wall of the conveying pipe. When the spiral conveyor paddle rotates, it drives the dispensing plate to rotate synchronously through the fixed rod. During the rotation, the dispensing plate can scrape off the residual powder on the inner wall of the conveying pipe. A main shaft is movably installed inside the discharge pipe. The main shaft is arranged along the axial direction of the discharge pipe. A material-dispensing plate is installed on the circumferential side of the main shaft. The material-dispensing plate is located inside the discharge pipe and can contact the dispensing plate. When the dispensing plate rotates and contacts the material-dispensing plate, it will drive the material-dispensing plate and the main shaft to rotate together. The rotating material-dispensing plate can disperse the powder in the discharge pipe and prevent agglomeration and blockage.

[0007] Preferably, a powerful blower is installed at the top of the conveying pipe via a fixing plate. The fixing plate secures the powerful blower above the conveying pipe, ensuring stable operation. An air supply pipe is installed through the output end of the powerful blower. One end of the air supply pipe is connected to the conveying pipe, and the air supply pipe guides the airflow generated by the powerful blower into the conveying pipe. The airflow assists in pushing the powder to convey the material, accelerating the conveying speed, and also blows away the fine powder residue on the pipe wall, enhancing the cleaning effect in conjunction with the push plate.

[0008] Preferably, the material feeding plate is equipped with teeth at both ends, which are distributed on the edges of both ends of the material feeding plate. When the material feeding plate rotates and disperses the powder, these teeth can enhance the cutting and stirring ability of the powder, make it easier to break up powder clumps, and improve the feeding effect.

[0009] Preferably, multiple material feeding plates are installed, and the multiple material feeding plates are installed at equal distances on the circumferential side of the main shaft and are radially distributed around the main shaft. The simultaneous operation of multiple material feeding plates expands the agitation range of the powder in the discharge pipe, which can more comprehensively disperse the powder and reduce the possibility of agglomeration and blockage.

[0010] Preferably, multiple dialing plates are installed, and each dialing plate is fixed to the spiral conveyor paddle by a fixing rod and distributed circumferentially along the axis of the spiral conveyor paddle. When the multiple dialing plates rotate with the spiral conveyor paddle, they can make more comprehensive contact with the inner wall of the conveying pipe, improve the cleaning effect of residual powder on the pipe wall, and increase the probability of contact with the material-dispensing plate to ensure that the material-dispensing plate can rotate stably.

[0011] Preferably, a controller is installed on the outer surface of the material tank body. The controller is electrically connected to electrical components such as the drive motor and the powerful fan. The controller can control the start-up, stop and operation status of the drive motor and the powerful fan, coordinate the work of each component, and ensure the efficient and stable operation of the device.

[0012] Compared with related technologies, the large-scale powder conveying device for material tanks provided by this utility model has the following beneficial effects:

[0013] Compared with existing technologies, when the drive motor rotates the screw conveyor, the screw conveyor shaft drives the pusher plate to rotate synchronously through the fixed rod. During the rotation of the pusher plate, it will have a linkage effect on the main shaft inside the discharge pipe, causing the main shaft to drive the pusher plate to rotate. The rotation of the pusher plate can actively disperse and agitate the powder falling from the bottom of the tank, effectively preventing the powder from forming clumps due to gravity compaction and causing blockage of the discharge pipe, thus ensuring continuous powder falling.

[0014] Compared with existing technologies, the powerful fan installed at the top of the conveying pipe blows strong air into the conveying pipe through the air duct. The strong air can help to move the powder in the conveying pipe and speed up the conveying speed. At the same time, the airflow can sweep away the fine powder residue on the pipe wall, further reducing the residue. Combined with the push plate, it forms a dual cleaning effect, enhancing the thoroughness of cleaning. It is especially suitable for conveying powder with high humidity, reducing the risk of residual powder hardening due to moisture.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0024] Please refer to the following: Figure 1-5A large-scale powder conveying device includes a tank body 1. A discharge pipe 3 is installed through the bottom of the tank body 1, and the discharge pipe 3 is connected to the interior of the tank body 1, serving as a channel for powder to fall from the tank body 1. The through structure ensures that the powder can smoothly enter the discharge pipe 3. A conveying pipe 4 is installed through the bottom of the discharge pipe 3. The conveying pipe 4 is arranged horizontally to receive the powder falling from the discharge pipe 3. The through connection between the discharge pipe 3 and the conveying pipe 4 realizes the transition from vertical to horizontal conveying of powder. A drive motor 5 is installed at one end of the conveying pipe 4. The drive motor 5 is fixed to the outside of the end of the conveying pipe 4, providing a power source for the device. A spiral conveying paddle 7 is connected to the output end of the drive motor 5 through the surface of the conveying pipe 4. The spiral conveying paddle 7 is located inside the conveying pipe 4, and its paddle shaft is coaxially fixed with the output end of the drive motor 5, so that the drive motor... Machine 5 can directly drive the spiral conveyor 7 to rotate inside the conveying pipe 4, thereby pushing the powder to move. A fixed rod 9 is installed on the circumferential side of the spiral conveyor 7 shaft, and a paving plate 8 is installed at one end of the fixed rod 9. The paving plate 8 is close to the inner wall of the conveying pipe 4. When the spiral conveyor 7 rotates, it drives the paving plate 8 to rotate synchronously through the fixed rod 9. During the rotation, the paving plate 8 can scrape off the residual powder on the inner wall of the conveying pipe 4. A main shaft 10 is movably installed inside the discharge pipe 3. The main shaft 10 is arranged along the axial direction of the discharge pipe 3. A material-pushing plate 11 is installed on the circumferential side of the main shaft 10. The material-pushing plate 11 is located inside the discharge pipe 3 and can contact the paving plate 8. When the paving plate 8 rotates and contacts the material-pushing plate 11, it will drive the material-pushing plate 11 and the main shaft 10 to rotate together. The rotating material-pushing plate 11 can disperse the powder in the discharge pipe 3 to prevent agglomeration and blockage. Example 2

[0025] Please refer to the following: Figure 1-5 A powerful blower 6 is mounted on the top of the conveying pipe 4 via a fixing plate. The fixing plate is made of L-shaped steel plate, with one end fixed to the outer wall of the top of the conveying pipe 4 by bolts, and the other end welded to a blower mounting platform. The powerful blower 6 is fixed to the platform with anchor bolts. Reinforcing ribs are welded below the platform to enhance load-bearing capacity. The installation position of the powerful blower 6 is downstream of the connection point between the discharge pipe 3 and the conveying pipe 4 (along the powder conveying direction) to ensure that the wind power effectively blows the powder in the subsequent pipe section; The output end of the powerful blower 6 is connected to an air supply pipe 13. One end of the air supply pipe 13 is connected to the conveying pipe 4. A circular flange is welded to the air outlet of the powerful blower 6. The air supply pipe 13 is made of galvanized steel pipe. One end is bolted to the air outlet of the blower through the flange, and the other end is fixed to the air outlet at the top of the conveying pipe 4 by welding. A guide plate is installed inside the connection to make the airflow blow along the axial direction of the conveying pipe 4. The connection point between the air supply pipe 13 and the conveying pipe 4 is located upstream of the starting position of the dialing plate 8 to ensure that the airflow can cooperate with the dialing plate 8 to form a double cleaning effect. Example 3

[0026] Please refer to the following: Figure 1-5The feeding plate 11 is equipped with teeth 12 at both ends. The teeth 12 are made of triangular wear-resistant steel sheets and are fixed to the upper and lower edges of the feeding plate 11 by welding. The spacing between the teeth 12 is 5-8mm, and the tips of the teeth face the rotation direction of the feeding plate 11. When the feeding plate 11 rotates, the teeth 12 can insert into the clumps of powder and break large clumps into small particles. Combined with the stirring effect of the feeding plate 11, the looseness of the powder is enhanced. It is especially suitable for powders with high moisture content that are prone to clumping. Example 4

[0027] Please refer to the following: Figure 1-5 Multiple material feeding plates 11 are installed, and the multiple material feeding plates 11 are installed at equal intervals on the side of the main shaft 10. Along the length of the main shaft 10, a set of material feeding plates 11 is welded at every 10cm interval. Each set of 3 material feeding plates 11 is evenly distributed at 120° along the circumference of the main shaft 10. Adjacent sets of material feeding plates 11 are staggered by 60° in the circumferential position to form a spiral arrangement. This layout allows the powder in the discharge pipe 3 to be continuously stirred by multiple layers of material feeding plates 11 in the vertical direction, avoiding the occurrence of stirring dead corners and ensuring that the powder in the entire cross section of the discharge pipe 3 remains in a loose state. Example 5

[0028] Please refer to the following: Figure 1-5 Multiple dialing plates 8 are installed, and each dialing plate 8 is fixed to the spiral conveyor 7 by a fixing rod 9. Along the length of the spiral conveyor 7 shaft, from the connection point between the discharge pipe 3 and the conveying pipe 4 to the end of the conveying pipe 4, a set of dialing plates 8 is set at 20cm intervals. Each set has 2 dialing plates 8 symmetrically distributed around the shaft. The connection end of the dialing plate 8 and the fixing rod 9 is provided with a waist-shaped hole. The gap between the dialing plate 8 and the inner wall of the conveying pipe 4 can be changed by adjusting the position of the bolts to adapt to the cleaning needs under different wear levels. Multiple dialing plates 8 form a continuous cleaning area to ensure that there is no residual powder accumulation on the inner wall of the conveying pipe 4 throughout the process. Example 6

[0029] Please refer to the following: Figure 1-5 A controller 2 is installed on the outer surface of the material tank body 1. The controller 2 is fixed to the upper part of the outer wall of the material tank body 1 by bracket bolts, which is convenient for operators to observe and operate. The internal circuit of the controller 2 is connected to the drive motor 5 and the powerful fan 6 through cables. The cables are protected by being run through a metal corrugated pipe. The two ends of the corrugated pipe are sealed to the controller 2 and the equipment junction box, respectively. The controller 2 can adjust the speed of the drive motor 5 and the air volume of the powerful fan 6. By setting different parameters, it can adapt to the conveying needs of different types of powder materials and realize the intelligent control of the equipment.

[0030] It should be noted that the control circuit of controller 2 can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0031] The working principle of the large-scale powder conveying device for material tanks provided by this utility model is as follows:

[0032] When this large powder conveying device is in operation, the powder is stored inside the tank body 1 and gathers towards the bottom discharge pipe 3 under the action of gravity. At this time, the drive motor 5 at one end of the conveying pipe 4 starts, and its output end drives the spiral conveyor 7 to rotate inside the conveying pipe 4. The shaft of the spiral conveyor 7 drives the dialing plate 8 to rotate synchronously through the fixed rod 9. Since the dialing plate 8 will contact the dialing plate 11 inside the discharge pipe 3 during the rotation process, and the main shaft 10 is connected to the dialing plate 11, the dialing plate 8 will drive the dialing plate 11 and the main shaft 10 to rotate together.

[0033] The rotating material-dispersing plate 11 continuously disperses and agitates the powder accumulated in the discharge pipe 3, breaking up any clumps that may form due to gravity compaction. This ensures the powder passes smoothly through the discharge pipe 3 into the conveying pipe 4 in a loose state, preventing blockage. Simultaneously, the blades of the screw conveyor 7 push the powder entering the conveying pipe 4 towards the other end, achieving directional conveying of the powder. During this process, the dispersing plate 8 continuously contacts the inner wall of the conveying pipe 4, scraping off any residual powder adhering to the pipe wall. The scraped-off powder is conveyed along with the main powder flow, reducing material residue.

[0034] In addition, the powerful blower 6 at the top of the conveying pipe 4 is activated, continuously blowing high-pressure airflow into the conveying pipe 4 through the air duct 13. The airflow exerts thrust on the powder inside the conveying pipe 4, assisting the spiral conveyor 7 in accelerating the powder conveying speed; on the other hand, the airflow can penetrate deep into the gaps and dead corners inside the conveying pipe 4, blowing away any fine residual powder not completely cleaned by the brush plate 8, further improving the cleaning effect. Throughout the process, the controller 2 regulates the operating status of the drive motor 5 and the powerful blower 6 to ensure that all components work together to achieve efficient and stable powder conveying.

[0035] It should be noted that all components used in this application are standard parts that can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the prior art. The mechanical parts and electrical equipment adopt conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art.
