Abstract
Description
Technical Field
[0001] This invention belongs to the field of conveyor technology, and specifically relates to an anti-expansion tube system for a tubular belt conveyor. Background Technology
[0002] When a rectangular belt conveyor is conveying lime material, if there are large pieces of material or an excessive amount of material at the discharge point of the square discharge pipe, the pipe is prone to bulging at the tail end of the conveyor, which can damage the belt idler frame and may also fall onto the floor of the corridor, posing a production safety risk. Summary of the Invention
[0003] The purpose of this invention is to solve the above-mentioned problems and provide a device for removing iron oxide scale from the surface of steel profiles.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A tubular belt conveyor anti-expansion system includes a material crushing device, a triggering device, and a control system; The material crushing device includes a motor, a planetary gear carrier, a first crushing rod, and several second crushing rods. An installation hole is provided on the lower side wall of the square feed pipe. The planetary gear carrier is fixed inside the installation hole. A sun gear is located in the center of the planetary gear carrier, and several planetary gears mesh around the sun gear. One end of the first crushing rod is coaxially and fixedly connected to the sun gear. One end of each of the several second crushing rods is coaxially and fixedly connected to several planetary gears. The other ends of both the first and second crushing rods are connected to the opposite side wall of the feed pipe via bearings. The motor is fixedly mounted on the end face of the planetary gear carrier, and the motor's output shaft passes through the end face of the planetary gear carrier and is fixedly connected to the first crushing rod. Several first protrusions are evenly distributed on the outer surface of the first crushing rod, and several second protrusions are evenly distributed on the outer surface of the second crushing rods. The triggering device includes a support rod, a swing baffle, a contact head, a limit switch, and a fixed baffle. An inverted "U" bracket is provided on the conveyor in front of the feed pipe along the material conveying direction. A support rod is provided in the middle of the top surface of the bracket along the conveying direction. The front end of the support rod extends beyond the bracket. The fixed baffle is fixedly mounted on the front end surface of the support rod. The swing baffle is hinged to the bottom surface of the support rod behind the fixed baffle in a rotating manner. A gap is left between the lower end of the swing baffle and the conveyor. The contact head is fixed in the middle of the side of the swing baffle opposite to the fixed baffle. The limit switch is fixed in the middle of the side of the fixed baffle opposite to the swing baffle. The control system includes a controller, a data acquisition and processing module, an actuator module, a display module, and an alarm module. The controller has a preset contact time threshold t between the contact head and the limit switch. When the actual contact time t1 is greater than the preset contact time threshold t, it indicates that too much material has been fed and tube expansion will occur. When the actual contact time t1 is less than or equal to the contact time threshold t, it indicates that there are some large, unbroken particles remaining in the material, causing the contact head to accidentally contact the limit switch, and the material will not expand. The controller is electrically connected to the data acquisition and processing module, the actuator module, the display module, and the alarm module, respectively. The actuator module is electrically connected to the conveyor and the motor, respectively. The conveyor and the motor are electrically connected to the data acquisition and processing module, respectively. The data acquisition and processing module is electrically connected to the limit switch.
[0005] Furthermore, the first protrusion and the second protrusion are misaligned with each other.
[0006] Furthermore, a return spring is provided at the lower part between the swing baffle and the fixed baffle.
[0007] Furthermore, the height of the fixed baffle is less than the height of the swing baffle.
[0008] Furthermore, the alarm module adopts a voice alarm or an audible and visual alarm.
[0009] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention can crush large pieces of material during the feeding process by setting up a material crushing device. By setting up a triggering device and interlocking it with the control system, the expansion of the tube can be further prevented. 2. The controller of the present invention has a preset contact time threshold, which can effectively prevent the occurrence of accidental collisions and further improve production efficiency; 3. By effectively preventing tube expansion, this invention can effectively improve production efficiency, reduce production accidents, and extend equipment service life. 4. This invention enables automated operation, eliminating the need for human intervention and reducing production costs. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example
[0012] like Figure 1-6 As shown, a tubular belt conveyor anti-expansion system includes a material crushing device, a triggering device, and a control system. The material crushing device includes a motor 4, a planetary gear carrier 5, a first crushing rod 6, and several second crushing rods 7. An installation hole is provided on the lower side wall of the square feed pipe 1. The planetary gear carrier 5 is fixedly installed in the installation hole. The center of the planetary gear carrier 5 is a sun gear, and several planetary gears mesh around the sun gear. One end of the first crushing rod 6 is coaxially and fixedly connected to the sun gear. One end of each of the several second crushing rods 7 is coaxially and fixedly connected to several planetary gears. The other ends of both the first crushing rod 6 and the second crushing rods 7 are connected to the opposite side wall of the feed pipe 1 via bearings. The motor 4 is fixedly installed on the end face of the planetary gear carrier 5, and the output shaft of the motor 4 passes through the end face of the planetary gear carrier 5 and is fixedly connected to the first crushing rod 6. Several first protrusions 8 are evenly distributed on the outer surface of the first crushing rod 6, and several second protrusions 9 are evenly distributed on the outer surface of the second crushing rods 7, with the first protrusions 8 and second protrusions 9 being staggered. The triggering device includes a support rod 10, a swing baffle 11, a contact head 12, a limit switch 13, and a fixed baffle 15. An inverted "U" bracket 3 is provided on the conveyor 2 in front of the feed pipe 1 along the material conveying direction. The support rod 10 is provided in the middle of the top surface of the bracket 3 along the conveying direction. The front end of the support rod 10 extends beyond the bracket 3. The fixed baffle 15 is fixedly mounted on the front end surface of the support rod 10. The swing baffle 11 is hinged to the bottom surface of the support rod 10 behind the fixed baffle 15 in a rotating manner. A 6cm gap is left between the lower end of the swing baffle 11 and the conveyor 2. The height of the fixed baffle 15 is less than the height of the swing baffle 11. The contact head 12 is fixed in the middle of the side of the swing baffle 11 opposite to the fixed baffle 15. The limit switch 13 is fixed in the middle of the side of the fixed baffle 15 opposite to the swing baffle 11. A return spring 14 is also provided at the lower part between the swing baffle 11 and the fixed baffle 15. The control system includes a controller, a data acquisition and processing module, an actuator module, a display module, and a voice alarm module. The controller has a preset contact time threshold t of 30s between the contact head 12 and the limit switch 13. When the actual contact time t1 is greater than 10s, it indicates that too much material has been fed and the tube will soon expand. When the actual contact time t1 is less than or equal to 10s, it indicates that there are some large, unbroken particles remaining in the material, which will cause the contact head 12 to accidentally contact the limit switch 13 and the material will not expand. The controller is electrically connected to the data acquisition and processing module, the actuator module, the display module, and the alarm module, respectively. The actuator module is electrically connected to the conveyor 2 and the motor 4, respectively. The conveyor 2 and the motor 4 are electrically connected to the data acquisition and processing module, respectively. The data acquisition and processing module is electrically connected to the limit switch 13.
[0013] The alarm module can also be an audible and visual alarm.
[0014] The preset contact time threshold t is 10s. Conveyor 2 and motor 4 are started. Motor 4 drives the sun gear and the first crushing rod 6 to rotate, thereby causing the surrounding planetary gears and the second crushing rod 7 to revolve and rotate. When lime granules fall from the feed pipe 1, they first land on the first crushing rod 6 and the second crushing rod 7. Small pieces fall directly through the gap between the first protrusion 8 and the second protrusion 9. Large pieces of material, due to agglomeration, are crushed by the first protrusion 8 and the second protrusion 9 and fall onto the conveyor 2, moving forward. Small granules can be transported forward normally, while large or accumulated materials exert a forward thrust on the swing baffle 11, pushing it forward and compressing the return spring 14. The contact head 12 contacts the limit switch 13, connecting the circuit and transmitting the signal to the... The data is collected and processed by the data acquisition module and fed back to the controller. When the actual contact time t1 ≤ the contact time threshold t, it indicates that the material passing through is a few large pieces that have not been broken. At this time, there is a false contact between the contact head 12 and the limit switch 13. The controller does not issue an instruction, and the system continues to run. However, when the actual contact time t1 is greater than the contact time threshold t, it indicates that there is too much material and accumulation, which is very likely to cause tube expansion. At this time, the limit switch 13 transmits a signal to the data acquisition and processing module and feeds it back to the controller. The controller issues an instruction to the actuator module, which controls the conveyor 2 and the motor 4 to stop running. At the same time, the controller controls the alarm module to issue an alarm and displays it on the display module to remind the operators to check and maintain. Timely shutdown can effectively prevent tube expansion from occurring in the next step.
