Description

Technical Field

[0001] This invention relates to the technical field of conveying equipment, specifically to an intelligent tubular chain conveying device and its usage method. Background Technology

[0002] A tubular chain conveyor is a continuous conveying device for transporting bulk materials such as powders, small granules, and small lumps. It can transport materials horizontally, inclined, and vertically in combination. It is commonly used in the fine chemical, pesticide and ore, building materials, and food industries.

[0003] Existing tubular chain conveyors typically consist of two pipes for circulating a chain with sprockets. One pipe is used to transport materials, while the other pipe is used only for circulating the chain when unloaded. Current technology does not consider the amount of material being fed. When the amount of material is suddenly increased, the chain may become overloaded and break, causing the equipment to stop operating. In addition, when conveying powders with high moisture content, the powder tends to clump and stick to the inner wall of the pipe, placing a large load on the power equipment. Therefore, a new technical solution is needed to address these technical problems. Summary of the Invention

[0004] This application proposes an intelligent tubular chain conveying device and its usage method, which can intelligently uniformly feed materials to avoid excessive chain load due to excessive feeding amount, which could lead to chain breakage during long-term operation. At the same time, it can also automatically stir the materials during conveying to prevent them from sticking together.

[0005] To this end, the first aspect of this application provides an intelligent tubular chain conveying device, including a conveying pipe and a return chain pipe. One end of the conveying pipe and the return chain pipe is provided with a drive housing, and a drive sprocket is rotatably provided inside the drive housing. The other end of the conveying pipe and the return chain pipe is provided with a driven housing, and a driven sprocket is rotatably provided inside the driven housing. A transmission chain is sleeved between the drive sprocket and the driven sprocket. The transmission chain circulates in the conveying pipe and the return chain pipe. A feeding and loosening mechanism is provided on the transmission chain. A feeding port is provided at the lower part of the conveying pipe, and a discharging port is provided at the lower part of the drive housing. An induction and equalization mechanism is provided between the conveying pipe and the return chain pipe. The device also includes a drive motor for driving the drive sprocket to rotate.

[0006] By adopting the above technical solution: the drive motor drives the drive sprocket to rotate, the drive sprocket drives the transmission chain to rotate cyclically inside the conveying pipe and the return pipe, and the transmission chain drives the feeding and loosening mechanism to rotate cyclically inside the conveying pipe and the return pipe, so as to convey the material at the feed port of the conveying pipe to the discharge port to complete the conveying. During the conveying process, when the feed amount is too large, the induction uniform material mechanism can disperse some of the material into the return pipe for return, so as to achieve as uniform feeding as possible. In addition, during the feeding process, the feeding and loosening mechanism can loosen the material inside the conveying pipe to prevent the material with high moisture content from clumping and sticking to the inner wall of the conveying pipe.

[0007] Preferably, the drive housing is provided with a drive motor, which drives and connects to the drive sprocket.

[0008] By adopting the above technical solution, the rotation of the drive motor can drive the drive sprocket to rotate, which in turn can drive the transmission chain to rotate cyclically inside the conveying pipeline and the return pipeline, thereby realizing the material transfer.

[0009] Preferably, the induction material leveling mechanism includes an induction component disposed on the conveying pipe or the output shaft of the drive motor, a control component disposed on the drive housing, the induction component being communicatively connected to the control component, and the control component being driven and connected to a return material component.

[0010] By adopting the above technical solution, the sensing component can sense the amount of material being fed into the conveying pipe and transmit the feeding signal to the control component. The control component can control the operation of the return component to release some material into the empty return chain pipe, feeding it as evenly as possible again, preventing the chain from being overloaded and breaking after long-term operation, and improving the service life of the equipment.

[0011] Preferably, the sensing component includes a material quantity sensor disposed on the conveying pipe or a torque sensor disposed on the output shaft of the drive motor, and the control component includes a controller disposed on the drive housing, wherein the material quantity sensor and the torque sensor are electrically connected to the controller.

[0012] By adopting the above technical solution: when the material quantity sensor senses that the material quantity is large, or when the torque sensor detects that the output torque of the output shaft is too large, the signal is transmitted to the controller. The controller can control the operation of the return material component to put some material back into the return chain pipe and send it back to the feeding port.

[0013] Preferably, the return assembly includes a return inclined pipe connecting the conveying pipe and the return chain pipe, a material gate is inserted at the connection between the return inclined pipe and the conveying pipe, the material gate is driven and connected to a telescopic power component fixed on the conveying pipe, and the telescopic power component is electrically connected to a controller.

[0014] By adopting the above technical solution: when the feeding amount is too large, the controller controls the telescopic power component to pull the material gate open, and the material can enter the return inclined pipe. After passing through the return inclined pipe, it enters the return chain pipe. Similarly, the feeding and loosening mechanism inside the return chain pipe can bring the material back to the feeding port, and then feed it as evenly as possible to prevent the chain from being overloaded and the transmission chain from breaking due to long-term operation.

[0015] Preferably, the feeding and loosening mechanism includes a base plate fixed on a transmission chain, a rotating loosening component rotatably connected to the base plate, and a triggering component for driving the rotating loosening component on the conveying pipe.

[0016] By adopting the above technical solution: the base plate is fixed on the transmission chain and rotates in the conveying pipeline and return pipeline under the drive of the transmission chain. At the same time, the base plate serves as an installation base, and the rotating loosening component installed on it is used to convey materials and to stir the materials during the conveying process to prevent them from clumping. The trigger component can drive the rotating loosening component to move.

[0017] Preferably, the rotating loosening assembly includes a rotating ring body rotatably mounted on a base plate. The periphery of the rotating ring body contacts the inner wall of the conveying pipe. A radial loosening rod is provided on the inner side of the rotating ring body, and an axial loosening rod is provided on the side of the rotating ring body. An annular limiting groove is provided on the base plate, and a limiting rail that cooperates with the annular limiting groove is provided on the rotating ring body.

[0018] By adopting the above technical solution: during the material conveying process, the rotating ring can rotate relative to the material during the movement, that is, during the material conveying process, it can rotate relative to the material. The radial loosening rod and the axial loosening rod can stir the material and prevent the material from clumping.

[0019] Preferably, the triggering component includes a triggering rod disposed inside the conveying pipe, and the rotating ring body has a driven inclined groove on its circumference.

[0020] By adopting the above technical solution: when the rotating ring moves to the contacting rod, since the contacting rod is fixed, after it enters the inside of the driven inclined groove, it forces the rotating ring to rotate while moving, thereby stirring the material through the radial loosening rod and the axial loosening rod.

[0021] Preferably, the triggering component includes a spiral rail disposed on the inner wall of the conveying pipe, and the circumference of the rotating ring is provided with a groove that slides on the spiral rail.

[0022] By adopting the above technical solution: when the rotating ring moves, with the cooperation of the spiral rail and the slide, the rotating ring rotates according to the trajectory of the spiral rail, thereby stirring the material through the radial loosening rod and the axial loosening rod.

[0023] A second aspect of this application provides a method for using the aforementioned intelligent tubular chain conveying equipment, comprising the following steps:

[0024] Start the drive motor, which drives the transmission chain to rotate in the conveying pipe and return pipe. The material is fed at the loading port and pushed to the unloading port by the feeding and loosening mechanism in the conveying pipe. During the feeding process, the feeding and loosening mechanism loosens the material. When the feeding amount is too large, the material leveling mechanism senses the material amount signal and automatically returns part of the material to the loading port in the return pipe to achieve as uniform feeding as possible.

[0025] By adopting the above technical solution, the material feeding can be more uniform, preventing the chain from breaking due to excessive load during long-term operation. In addition, the material can be stirred while being conveyed to prevent it from clumping.

[0026] The working principle and beneficial effects of this application are as follows:

[0027] 1. This application uses a drive motor to drive a drive sprocket to rotate, which in turn drives a transmission chain to rotate cyclically inside the conveying pipe and the return pipe. The transmission chain drives a feeding and loosening mechanism to rotate cyclically inside the conveying pipe and the return pipe, thus conveying the material at the feed port of the conveying pipe to the discharge port. During the conveying process, when the feed amount is too large, the induction equalization mechanism can disperse some of the material into the return pipe for return, thereby maximizing the feeding. Furthermore, during the feeding process, the feeding and loosening mechanism can loosen the material inside the conveying pipe, preventing materials with high moisture content from clumping and sticking to the inner wall of the conveying pipe.

[0028] 2. In this application, the sensing component can sense the amount of material being fed into the conveying pipe and transmit the feeding amount signal to the control component. The control component can control the operation of the return component to release some material into the empty return chain pipe, and feed it evenly again, preventing the chain from being overloaded and breaking after long-term operation, thus improving the service life of the equipment.

[0029] 3. During the material conveying process, the rotating ring can rotate relative to the material as it moves. That is, during the material conveying process, it can rotate relative to the material. The radial and axial loosening rods can stir the material and prevent it from clumping.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] like Figures 1-8 As shown, the first aspect of this embodiment provides an intelligent tubular chain conveying device, including a conveying pipe 100 and a return chain pipe 200, which form a circulation loop. A drive housing 300 is provided at one end of the conveying pipe 100 and the return chain pipe 200, and a drive sprocket is rotatably mounted inside the drive housing 300. A driven housing 400 is provided at the other end of the conveying pipe 100 and the return chain pipe 200, and a driven sprocket is rotatably mounted inside the driven housing 400. The drive sprocket and... A drive chain 500 is sleeved between the driven sprockets. The drive chain 500 rotates cyclically in the conveying pipe 100 and the return chain pipe 200. A feeding and loosening mechanism 600 is provided on the drive chain 500. The lower part of the conveying pipe 100 is provided with a feeding port 110 for feeding. The lower part of the drive housing 300 is provided with a discharging port 310 for discharging. An induction and equalization mechanism 700 is provided between the conveying pipe 100 and the return chain pipe 200. The system also includes a drive motor 800 for driving the drive sprockets to rotate.

[0044] The basic principle of this embodiment is as follows: The drive motor 800 drives the drive sprocket to rotate, and the drive sprocket drives the transmission chain 500 to rotate cyclically inside the conveying pipe 100 and the return chain pipe 200. The transmission chain 500 drives the feeding and loosening mechanism 600 to rotate cyclically inside the conveying pipe 100 and the return chain pipe 200, so as to convey the material at the feed port 110 of the conveying pipe 100 to the discharge port 310 to complete the conveying. During the conveying process, when the feed amount is too large, the sensing and equalizing mechanism 700 can disperse some of the material into the return chain pipe 200 for return, so as to achieve as uniform feeding as possible. In addition, during the feeding process, the feeding and loosening mechanism 600 can loosen the material inside the conveying pipe 100 to prevent the material with high moisture content from clumping and sticking to the inner wall of the conveying pipe 100.

[0045] Reference Figures 1-3 The drive motor 800 is fixedly mounted in the drive housing 300. The output shaft of the drive motor 800 is connected to the drive sprocket by a key. Thus, the rotation of the drive motor 800 can drive the drive sprocket to rotate, which in turn drives the transmission chain 500 to circulate inside the conveying pipe 100 and the return chain pipe 200. This enables the material to be conveyed through the feeding and loosening mechanism 600.

[0046] Reference Figure 4In this embodiment, the sensing and leveling mechanism 700 includes a sensing component mounted on the conveying pipe 100 or the output shaft of the drive motor 800, and a control component mounted on the drive housing 300. The sensing component is communicatively connected to the control component, and the control component is driven and connected to the return material component. The sensing component can sense the amount of material being fed into the conveying pipe 100 and transmit the feeding amount signal to the control component. The control component can then control the return material component to release some material into the empty return chain pipe 200 for further leveling, preventing excessive chain load and breakage during prolonged operation, thus improving the service life of the equipment.

[0047] The sensing components include a material quantity sensor 710 installed on the conveying pipe 100 or a torque sensor installed on the output shaft of the drive motor 800. The control components include a controller installed on the drive housing 300. The material quantity sensor 710 and the torque sensor are electrically connected to the controller. When the material quantity sensor 710 senses a large amount of material, or when the torque sensor detects that the output torque of the output shaft is too large, it transmits a signal to the controller. The controller can control the return material component to put some material back into the return chain pipe 200 and send it back to the feeding port 110. In this embodiment, several material quantity sensors 710 can be added to the initial conveying pipe 100 section for feeding to facilitate the detection of the feeding amount. The material quantity sensor 710 can be a bulk density meter or other sensor capable of sensing the material quantity.

[0048] The material return assembly includes a return inclined pipe 720 connecting the conveying pipe 100 and the return chain pipe 200. The connection point between the return inclined pipe 720 and the conveying pipe 100 is higher than the connection point with the return chain pipe 200, facilitating material return. A material gate 730 is inserted at the connection point between the return inclined pipe 720 and the conveying pipe 100. The material gate 730 is driven by a telescopic power component 740 fixed to the conveying pipe 100. The telescopic power component 740 is electrically connected to a controller. When the material feeding amount is too large, the controller... The device controls the telescopic power component 740 to open the material gate 730, allowing the material to enter the return inclined pipe 720. After passing through the return inclined pipe 720, the material enters the return chain pipe 200. Similarly, the feeding and loosening mechanism 600 can bring the material back to the feeding port 110 for as even feeding as possible, preventing excessive chain load and long-term operation from causing the transmission chain 500 to break. The return chain pipe 200 has a material leakage port at the position opposite the feeding port 110, through which the material can enter the discharge port 310.

[0049] Reference Figure 3 and Figure 5The feeding and loosening mechanism 600 in this embodiment includes a base plate 610 fixed on a transmission chain 500. A rotating loosening component is rotatably connected to the base plate 610. An actuating component that drives the rotating loosening component is provided on the conveying pipe 100. The base plate 610 is fixed on the transmission chain 500 and circulates inside the conveying pipe 100 and the return pipe 200 under the drive of the transmission chain 500. At the same time, the base plate 610 serves as a mounting base. The rotating loosening component installed on it is used to convey materials and to stir the materials during the conveying process to prevent them from clumping. The actuating component can drive the rotating loosening component to move. In this embodiment, there is a certain gap between the edge of the base plate 610 and the inner wall of the conveying pipe 100 and the return pipe 200 to install the actuating component and prevent the base plate 610 from getting stuck. That is, the base plate 610 can pass through the actuating component.

[0050] Reference Figure 5 and Figure 6 In this embodiment, the rotating loosening assembly includes a rotating ring 620 rotatably mounted on a base plate 610. The periphery of the rotating ring 620 contacts the inner wall of the conveying pipe 100. A radial loosening rod 630 is provided on the inner side of the rotating ring 620, and an axial loosening rod 640 is provided on the side of the rotating ring 620. An annular limiting groove 650 is provided on the base plate 610, and a limiting rail 660 that cooperates with the annular limiting groove 650 is provided on the rotating ring 620. During material conveying, the rotating ring 620 can rotate relative to the material as it moves. The radial loosening rod 630 and the axial loosening rod 640 can agitate the material, preventing it from clumping. The rotating ring 620 has a hollow section in the middle to accommodate the transmission chain 500.

[0051] Reference Figure 7 In this embodiment, the actuating component includes an actuating rod 671 disposed inside the conveying pipe 100. The rotating ring 620 has a driven inclined groove 672 on its circumference. When the rotating ring 620 moves to the actuating rod 671, since the actuating rod 671 is fixed, it enters the driven inclined groove 672, forcing the rotating ring 620 to rotate while moving. This stirs the material through the radial loosening rod 630 and the axial loosening rod 640. To ensure the actuating rod 671 can smoothly enter the driven inclined groove 672, a guide port 673 is provided at the end of the driven inclined groove 672. The guide ports 673 are interconnected. Figure 7 As shown, when the rotating ring 620 moves to the right, its rotation direction is as follows: Figure 7 As indicated by the middle arrow.

[0052] A second aspect of this embodiment provides a method for using the aforementioned intelligent tubular chain conveying equipment, comprising the following steps:

[0053] Start the drive motor 800, which drives the transmission chain 500 to rotate cyclically inside the conveying pipe 100 and the return chain pipe 200. The material is fed at the feeding port 110 and pushed by the feeding loosening mechanism 600 in the conveying pipe 100 to the discharging port 310 for discharge. During the feeding process, the feeding loosening mechanism 600 loosens the material. When the feeding amount is too large, the sensing and equalizing mechanism 700 senses the material amount signal and automatically returns part of the material to the return chain pipe 200 and back to the feeding port 110 to achieve as uniform feeding as possible.

[0054] By using the above method to convey materials, the material feeding can be more uniform, preventing the chain from breaking due to excessive load during long-term operation. In addition, the materials can be stirred at the same time to prevent them from clumping.

[0055] Example 2

[0056] Reference Figure 8 The difference between this embodiment and Embodiment 1 is that the triggering component in this embodiment includes a spiral rail 681 disposed on the inner wall of the conveying pipe 100, and a groove 682 sliding on the spiral rail 681 is provided on the circumference of the rotating ring 620. When the rotating ring 620 moves, the rotating ring 620 rotates according to the trajectory of the spiral rail 681 under the cooperation of the spiral rail 681 and the groove 682, thereby stirring the material through the radial loosening rod 630 and the axial loosening rod 640. In order to enable the rotating ring 620 to rotate, the thickness of the rotating ring 620 in this embodiment can be smaller than that in the embodiment, so as to facilitate its rotation.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
