Description

Technical Field

[0001] This application relates to the technical field of material conveying equipment, and in particular to a bucket elevator. Background Technology

[0002] Bucket elevators are continuous conveying machines that use a series of buckets uniformly fixed to an uninterrupted traction component to vertically lift materials. Bucket elevators use a series of buckets fixed to a traction chain or belt to transport bulk materials upward in a vertical or near-vertical direction. They are divided into three types: ring chain, plate chain, and belt.

[0003] In a belt bucket elevator, when conveying materials, the drive unit drives the belt through a transmission drum. Buckets evenly distributed along the belt are loaded with material from the bottom loading area. As the belt rises continuously, the material in the buckets is lifted to the top unloading area, where it is discharged through the unloading port, completing one conveying cycle. The empty buckets then return to the bottom along the belt to continue the next cycle.

[0004] In related technologies, the drive device can generate high heat when driving the belt continuously for a long time, which may cause the belt to loosen, affect the material conveying speed, and thus have an adverse effect on work efficiency. Utility Model Content

[0005] In order to reduce the adverse impact on work efficiency, this application provides a bucket elevator.

[0006] The bucket elevator provided in this application adopts the following technical solution:

[0007] A bucket elevator includes a housing and a belt installed inside the housing and arranged along the height direction of the housing. The housing has a through hole extending along its own height direction. A mounting shell is installed on the housing to block the through hole. A drive roller is provided on the upper side of the belt and is rotatably connected to the housing to drive the belt. A driven roller is provided on the lower side of the belt and is rotatably connected to the mounting shell. A cooling component is provided in the mounting shell.

[0008] By adopting the above technical solution, the cooling component is installed inside the belt through the mounting shell. When the drive roller drives the belt for a long time and generates heat, the cooling component cools down the drive roller, driven roller and belt, reducing the adverse effects of belt heat loosening on the conveying speed, and thus reducing the adverse effects on work efficiency.

[0009] Optionally, the cooling component includes a condenser tube located inside the mounting housing and spirally arranged along the height direction of the mounting housing. Both ends of the condenser tube penetrate the mounting housing, and condensate is introduced into the condenser tube. The mounting housing is provided with an air-cooling component.

[0010] By adopting the above technical solution, condensate is introduced into the condenser tube, which is located inside the belt, thus facilitating the cooling of the belt, drive roller, and driven roller. Furthermore, an air-cooling component is installed in the mounting housing, which further cools the belt, drive roller, and driven roller, reducing the adverse effects of belt relaxation due to heat on the conveying speed, and thus reducing the adverse effects on work efficiency.

[0011] Optionally, the air-cooled component includes an air inlet pipe installed in the middle of one side of the mounting housing and communicating with the interior of the mounting housing; a guide fan is installed at the end of the mounting housing and on the side near the air inlet pipe; and an exhaust pipe is installed at the end of the mounting housing away from the air inlet pipe, penetrating the mounting housing.

[0012] By adopting the above technical solution, air is introduced into the mounting housing from the air inlet pipe. At this time, the guide fan rotates and drives the air entering the mounting housing to move towards both ends of the mounting housing and come into contact with the condenser pipe, thereby being further cooled by the condenser pipe. When the air moves to both ends of the mounting housing, it is driven by the guide fan to contact the drive roller and the driven roller respectively, and moves along the length of the drive roller and is discharged along the corresponding exhaust pipe. This facilitates the cooling of the drive roller and the driven roller, reduces the adverse effect of belt slack due to heat on the conveying speed, and thus reduces the adverse effect on work efficiency.

[0013] Optionally, temperature sensors are installed at both ends inside the mounting housing.

[0014] By adopting the above technical solution, the temperature sensor installed at the end of the housing monitors the temperature changes of the drive roller and driven roller in real time. When the temperature of the drive roller and driven roller is high, condensate is introduced into the condenser pipe and air is introduced into the air inlet pipe. In this way, the belt, drive roller and driven roller are cooled by a combination of water cooling and air cooling, which reduces the adverse effect of belt heat loosening on the conveying speed and thus reduces the adverse effect on work efficiency.

[0015] Optionally, a tensioning assembly for tensioning the belt is provided on the lower side of the mounting housing.

[0016] By adopting the above technical solution, when the belt becomes slack, the belt is tightened by the tensioning component, which reduces the adverse effects of belt slack deformation on the conveying speed, while extending the service life of the belt and reducing the adverse effects on work efficiency.

[0017] Optionally, the tensioning assembly includes a drive shaft that passes through the driven roller, is coaxial with and rotatably connected to the driven roller, and the ends of the drive shaft all pass through the sidewall of the mounting housing and are slidably connected to the mounting housing along the height direction of the mounting housing. Hydraulic cylinders for driving the drive shaft to move are provided on both sides of the outside of the mounting housing.

[0018] By adopting the above technical solution, when the belt is slack, the hydraulic cylinder drives the end of the drive shaft to move the driven roller downwards simultaneously until the belt is tensioned. The drive shaft and the driven roller are rotatably connected, which does not affect the rotation of the driven roller driven by the belt. This facilitates belt tensioning, reduces the adverse effects of belt slack and deformation on the conveying speed, extends the belt's service life, and reduces the adverse effects on work efficiency.

[0019] Optionally, a pressure sensor is mounted on the lower side of the drive shaft, and the driven roller can contact the pressure sensor.

[0020] By adopting the above technical solution, during the process of the hydraulic cylinder driving the driven roller to move and tension the belt through the drive shaft, the pressure sensor is located between the driven roller and the drive shaft and monitors the pressure between the driven roller and the drive shaft. When the pressure sensor detects that the belt is tensioned, the hydraulic cylinder stops driving the drive shaft to move, thereby facilitating the tensioning of the belt, reducing the adverse effects of belt slack and deformation on the conveying speed, and extending the service life of the belt, reducing the adverse effects on work efficiency.

[0021] Optionally, a filter plate is installed on the lower side of each of the guide fans.

[0022] By adopting the above technical solution, when the air is driven by the guide fan and passes through the guide fan, it first comes into contact with the filter plate. At this time, the filter plate traps the impurities that move with the wind, reducing the possibility of impurities damaging the guide fan and reducing the adverse impact on work efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Condensate is introduced into the condenser tube. At this time, the condenser tube is located inside the belt, which facilitates the cooling of the belt, drive roller and driven roller. The mounting shell is equipped with air-cooling components, which further cools the belt, drive roller and driven roller, reducing the adverse effects of belt relaxation due to heat on the conveying speed, and thus reducing the adverse effects on work efficiency.

[0025] 2. Air is introduced into the mounting housing through the air inlet pipe. At this time, the guide fan rotates and drives the air entering the mounting housing to move towards both ends of the mounting housing and come into contact with the condenser pipe, so that it is further cooled by the condenser pipe. When the air moves to both ends of the mounting housing, it is driven by the guide fan to come into contact with the drive roller and the driven roller respectively, and moves along the length of the drive roller and is discharged along the corresponding exhaust pipe, so as to facilitate the cooling of the drive roller and the driven roller.

[0026] 3. The hydraulic cylinder drives the end of the drive shaft to move the driven roller downwards simultaneously until the belt is tensioned. The drive shaft and the driven roller are rotatably connected, which does not affect the rotation of the driven roller driven by the belt. This facilitates belt tensioning, reduces the adverse effects of belt slack and deformation on the conveying speed, extends the belt's service life, and reduces the adverse effects on work efficiency.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a bucket elevator. (Refer to...) Figure 1 and Figure 2 A bucket elevator includes a vertical housing 1. A vertical through-hole 11 is formed on one vertical side of the housing 1 along its length. A mounting shell 2 is installed on the housing 1 to seal the through-hole 11. (Refer to...) Figure 1 and Figure 3 The housing 1 is provided with a vertical belt 3 located in the middle of the housing 1. The belt 3 is arranged along the edge of the mounting housing 2 and the upper end of the belt 1 is located in the housing 1.

[0035] A drive roller 31, arranged along the width direction of the housing 1, is rotatably connected to the upper end of the housing 1. The upper end of the belt 3 is sleeved on the outside of the drive roller 31 and contacts the side wall of the drive roller 31. One end of the drive roller 31 passes through the side wall of the housing 1 and is equipped with a motor 311 that drives the drive roller 31 to rotate. The lower end of the belt 3 is equipped with a driven roller 32 located inside the mounting shell 2 and rotatably connected to the mounting shell 2. The driven roller 32 is parallel to the drive roller 31, and multiple evenly distributed hoppers 33 are installed on the outside of the belt 3. The mounting shell 2 is equipped with a cooling assembly 4 for cooling the belt 3, the drive roller 31, and the driven roller 32.

[0036] The cooling component 4 is installed inside the belt 3 through the mounting shell 2. When the motor 311 drives the belt 3 for a long time through the drive roller 31 and generates heat, the cooling component 4 cools down the drive roller 31, the driven roller 32 and the belt 3, reducing the adverse effects of the belt 3 becoming loose due to heat on the conveying speed.

[0037] Reference Figure 3 and Figure 4 The cooling component 4 includes a condenser tube 41 located in the mounting housing 2 and spirally arranged in a vertical direction. The ends of the condenser tube 41 all pass through the side wall of the mounting housing 2 and are fixedly connected to the mounting housing 2. Condensate is introduced into the condenser tube 41, and the mounting housing 2 is provided with an air-cooling component 42. The air-cooling component 42 includes an air inlet pipe 421 fixedly connected to the middle of one side of the mounting housing 2. The air inlet pipe 421 is horizontal and communicates with the interior of the mounting housing 2.

[0038] Mounting plates 21 are fixedly connected to both ends inside the mounting housing 2. The distance between the mounting plates 21 is less than the length of the mounting housing 2. A guide fan 422 communicating with the inside of the housing 1 is installed on the end of the mounting plate 21 near the air inlet pipe 421. A vertical exhaust pipe 423 communicating with the inside of the housing 1 is installed on the end of the mounting plate 21 away from the guide fan 422. The ends of the exhaust pipes 423 that are close to each other are bent to the side away from the guide fan 422 and are horizontal. The bent ends of the exhaust pipes 423 pass through the side wall of the mounting housing 2 and are fixedly connected to the mounting housing 2.

[0039] Temperature sensors (not shown in the figure) are installed at both ends inside the mounting housing 2, and a filter plate 424 fixedly connected to the mounting plate 21 is provided on the side of the guide fan 422 near the air inlet pipe 421. The diameter of the filter plate 424 is equal to the outer diameter of the guide fan 422.

[0040] Temperature sensors installed at the ends of the mounting housing 2 monitor the temperature changes at the drive roller 31 and driven roller 32 in real time. When the temperature at the drive roller 31 and driven roller 32 is high, condensate is introduced into the condenser pipe 41. At this time, the condenser pipe 41 is located inside the belt 3, which facilitates the cooling of the belt 3, drive roller 31 and driven roller 32. Air is introduced into the mounting housing 2 from the air inlet pipe 421. At this time, the guide fan 422 rotates and drives the air entering the mounting housing 2 to move towards both ends of the mounting housing 2 and contact the condenser pipe 41, thereby being further cooled by the condenser pipe 41. When the air moves to both ends of the mounting housing 2, it is driven by the guide fan 422 to contact the drive roller 31 and driven roller 32 respectively, and moves along the length of the drive roller 31 before being discharged along the corresponding exhaust pipe 423, which facilitates the cooling of the drive roller 31 and driven roller 32.

[0041] When the air is driven by the guide fan 422 and passes through the guide fan 422, it first comes into contact with the filter plate 424. At this time, the filter plate 424 intercepts the impurities that move with the wind, reducing the possibility of impurities damaging the guide fan 422.

[0042] Reference Figure 1 , Figure 2 and Figure 5 The mounting housing 2 has a tensioning assembly 5 for tensioning the belt 3 on its lower side. The tensioning assembly 5 includes a drive shaft 51 that passes through the driven roller 32 along its length. The length of the drive shaft 51 is greater than the length of the driven roller 32, and the drive shaft 51 is rotatably connected to the driven roller 32. Vertical moving holes 22 are provided on both sides of the lower end of the mounting housing 2. The ends of the drive shaft 51 pass through the corresponding moving holes 22 and are slidably connected to the mounting housing 2 in the vertical direction. A pressure sensor (not shown in the figure) is installed on the lower side of the middle part of the drive shaft 51 to detect the pressure between the driven roller 32 and the drive shaft 51.

[0043] Each drive shaft 51 has a mounting ring 52 sleeved on the outer side of the mounting housing 2. Each mounting ring 52 has a vertical hydraulic cylinder 53 fixedly connected to the outer wall of the housing 1. The telescopic rods of the hydraulic cylinders 53 are all pointing upwards and fixedly connected to the lower side of the corresponding mounting ring 52.

[0044] When belt 3 is slack, hydraulic cylinder 53 drives the end of drive shaft 51 through mounting ring 52 to move driven roller 32 downwards. Pressure sensor is located between driven roller 32 and drive shaft 51 and monitors the pressure between driven roller 32 and drive shaft 51. When pressure sensor detects that belt 3 is taut, hydraulic cylinder 53 stops driving drive shaft 51 to move. At this time, belt 3 is taut and drive shaft 51 is rotatably connected to driven roller 32, which does not affect belt 3 driving driven roller 32 to rotate.

[0045] The implementation principle of a bucket elevator according to an embodiment of this application is as follows: a temperature sensor monitors the temperature changes at the drive roller 31 and driven roller 32 in real time. When the temperature at the drive roller 31 and driven roller 32 is high, condensate is introduced into the condenser pipe 41 to cool the belt 3, drive roller 31 and driven roller 32. Air is introduced into the mounting shell 2 from the air inlet pipe 421. At this time, the guide fan 422 rotates and drives the air entering the mounting shell 2 to move towards both ends of the mounting shell 2 and contact the condenser pipe 41, thereby being further cooled by the condenser pipe 41. When the cooled air moves to both ends of the mounting shell 2, it is driven by the guide fan 422 to contact the drive roller 31 and driven roller 32 respectively and move along the length direction of the drive roller 31 before being discharged along the corresponding exhaust pipe 423, thereby facilitating the cooling of the drive roller 31 and driven roller 32.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
