Abstract
Description
Technical Field
[0001] The utility model relates to steel rolling dust removal equipment, in particular to a rotary dust collecting device. Background Art
[0002] A large amount of dust is generated during the steel rolling production process. In order to reduce the dust entering the surrounding environment, dust collection equipment is required. At the same time, steel rolling equipment often needs to be repaired. Therefore, it is required that the dust collection equipment should not affect the steel rolling production and maintenance operations. Utility Model Content
[0003] Purpose of the utility model: The purpose of the utility model is to provide a rotating dust collecting device which does not affect steel rolling production and maintenance operations.
[0004] Technical solution: The rotary dust collecting device described in the utility model comprises a dust collecting hood which rotates to a horizontal position on the rolling production line in the dust collecting state and rotates upward and flips up to be detached from the rolling center line in the maintenance state.
[0005] Furthermore, the rotary dust collecting device also includes a first connecting pipe, which is rotatably connected to a second connecting pipe on the dust collecting cover via a slewing bearing, and the second connecting pipe and the dust collecting cover are driven to rotate by a driving mechanism installed on the first connecting pipe.
[0006] Furthermore, the driving mechanism includes a motor, and a gear is provided at the output end of the motor; the slewing bearing includes an outer ring and an inner ring, wherein the outer ring is connected to the second connecting pipe, the inner ring is connected to the first connecting pipe, and the outer ring has a gear ring meshing with the gear.
[0007] Furthermore, the outer ring is connected to the second connecting pipe by bolts.
[0008] Furthermore, the inner ring is connected to the first connecting pipe by bolts.
[0009] Furthermore, the first connecting pipe and the second connecting pipe are both 90° elbows.
[0010] Furthermore, the first connecting pipe is connected to the air inlet pipe of the dust collector through the exhaust pipe.
[0011] Furthermore, the exhaust pipe is supported by a pipe rack.
[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages: the utility model provides a rotary dust collecting device, which has two working states, namely, the dust collecting state and the maintenance state. In the dust collecting state, the dust collecting hood is horizontally covered on the rolling production line, and can collect dust normally; in the maintenance state, the dust collecting hood is rotated upward and turned up, disengaged from the rolling center line, which is convenient for the maintenance of the rolling production line equipment.

[0016] Figure 4 This is a schematic diagram of the maintenance status of the rotating dust collecting device. DETAILED DESCRIPTION
[0017] The utility model is further described below in conjunction with the accompanying drawings.
[0018] Attached Figures 1 to 4 The reference numerals in the figures are as follows:
[0019] 1. Pipe rack; 2. Exhaust pipe; 3. First connecting pipe; 4. Motor; 5. Slewing bearing; 6. Gear; 7. Dust hood; 8. Outer ring; 9. Inner ring.
[0020] like Figures 1 to 3 As shown, a rotary dust collecting device includes a pipe rack 1, an exhaust pipe 2, a first connecting pipe 3, a motor 4, a slewing bearing 5, a gear 6 and a dust collecting cover 7.
[0021] The pipe rack 1 is installed on a concrete foundation, and an exhaust pipe 2 is installed and fixed on the pipe rack 1. One end of the exhaust pipe 2 is connected to an air inlet pipe of a dust collector, and dust is sent to the dust collector through the exhaust pipe 2.
[0022] The first connecting pipe 3 is a 90° elbow pipe installed at the other end of the exhaust pipe 2. The motor 4 is installed on the first connecting pipe 3, and the gear 6 is installed at the output end of the motor 4. The dust collecting hood 7 is connected with the second connecting pipe, which is also a 90° elbow pipe. The slewing bearing 5 has an outer ring 8 and an inner ring 9, wherein the outer ring 8 is connected to the second connecting pipe by bolts, and the inner ring 9 is connected to the first connecting pipe 3 by bolts, and the outer ring 8 has a gear ring meshing with the gear 6. The motor 4 can drive the outer ring 8 to rotate, thereby rotating the second connecting pipe and the dust collecting hood 7.
[0023] like Figure 1 As shown, in the dust collecting state, the dust collecting hood 7 is horizontally covered on the rolling production line to collect the dust generated during the steel rolling production process. Figure 4 As shown, in the maintenance state, the dust collecting hood 7 is rotated and flipped upward to be separated from the rolling center line, so as to facilitate the maintenance of the rolling production line equipment.
