Description

Technical Field

[0001] The invention belongs to the technical field of metallurgy, and in particular relates to a friction plate follower rolling sweeping device for an annular cooler and an annular cooler. Background Art

[0002] In the field of metallurgy, the ring cooler is the core equipment of the sintering and pelletizing process, which is used to cool the sintered ore produced by the sintering machine and the oxidized pelletized ore after roasting in the chain grate rotary kiln. Among the transmission forms of the ring cooler, friction transmission is widely used. The active friction wheel and the passive friction wheel clamp the friction plate on the rotating frame. The driving device drives the active friction wheel to rotate. The friction between the active friction wheel and the friction plate is used to push the friction plate to drive the rotating frame to rotate. Therefore, before the friction plate contacts the active friction wheel, it is necessary to ensure that the contact part of the friction plate is clean. If there are particles in the middle of the friction plate and the active friction wheel when they contact, the contact surface of the two will be separated, reducing the friction force used to drive the friction plate, causing the active friction wheel to slip. However, during the operation of the ring cooler, especially in the loading and unloading links, dust and some loose materials are easily dropped on the surface of the friction plate, resulting in particles in the middle of the friction plate and the active friction wheel when they contact. Summary of the invention

The power input end of the secondary speed-increasing transmission assembly 3 is transmission-connected to the power output end of the primary speed-increasing transmission assembly 2. The power output end of the secondary speed-increasing transmission assembly 3 is transmission-connected to the roller brush 4. The roller brush 4 is located on the plate surface of the friction plate 6. The axial direction of the roller brush 4 is parallel to the plate surface of the friction plate 6, and the axial direction of the roller brush 4 forms an angle with the radial direction of the friction plate 6.

[0035] In this embodiment, in order to ensure that the roller brush 4 effectively cleans the surface of the friction plate 6, the rotation direction of the roller brush 4 is opposite to that of the friction plate 6.

[0041] The one-stage speed-increasing transmission assembly 2 of this embodiment includes a first cylindrical gear 21 and a second cylindrical gear 22, and the second cylindrical gear 22 is meshed with the first cylindrical gear 21 for transmission. The first cylindrical gear 21 is in transmission connection with the friction wheel 1, so the first cylindrical gear 21 is the power input end of the one-stage speed-increasing transmission assembly 2, and the second cylindrical gear 22 is the power output end of the one-stage speed-increasing transmission assembly 2. The diameter of the first cylindrical gear 21 is greater than the diameter of the second cylindrical gear 22, which has the effect of speed increase and improves the speed output of the power output end of the one-stage speed-increasing transmission assembly 2.

The first cylindrical gear 21 and the friction wheel 1 are disposed on the half shaft 23, and the friction wheel 1 is located at one end of the half shaft 23 away from the first bearing 24.

[0043] In this embodiment, the friction wheel 1 and the first cylindrical gear 21 are driven by the half shaft 23 , so that the torque of the friction wheel 1 can be effectively transmitted to the first cylindrical gear 21 .

[0044] The first-stage speed increasing transmission assembly 2 of the present embodiment also includes a half shaft 23 and a first bearing 24. The first bearing 24 is fixedly arranged. The bottom end of the half shaft 23 is rotatably arranged in the first bearing 24.

The diameter of the first bevel gear 31 is greater than the diameter of the second bevel gear 32, which has the effect of speed-increasing, and improves the speed output of the power output end of the two-stage speed-increasing transmission assembly 3. Moreover, the present embodiment adopts the first bevel gear 31 and the second bevel gear 32 to transmit the speed and torque, which not only plays the role of speed-increasing again, but also realizes vertical redirection, so that the roller brush 4 can fit on the friction plate 6.
