Embodiment 1

[0036] like figure 1 , figure 2 , image 3 and Figure 4 As shown, a vibrating bead type labyrinth dust-proof grinding roller device, the shaft 18, the support assembly, the dust-proof assembly and the transmission assembly, the support assembly, the dust-proof assembly and the transmission assembly are sequentially sleeved on the shaft from top to bottom, and the existing There are technical differences in that,

[0037] The transmission assembly includes a grinding roller 4, a bearing sleeve 5, a first roller bearing 7, a second roller bearing 3, and a lower gland 1, and the bearing sleeve 5 passes through the first roller bearing 7 and the second roller bearing 3 is sleeved on the shaft 18, and a pressure sleeve 6 is set between the first roller bearing 7 and the second roller bearing 3 to be sleeved on the shaft 18, and the upper end surface of the pressure sleeve 6 withstands the inner ring of the first roller bearing 7 The lower end face, the lower end face of the p...

Embodiment 2

[0053] like Figure 5 , Image 6 , Figure 7 as shown,

[0054] In the labyrinth moving ring 13, the lower end surface and the upper end surface of the swivel are provided with a powder rejection gap 27, and the powder rejection gap 27 communicates with the powder rejection groove 24, so that the dust in the powder rejection groove 24 follows the rotation of the swivel ring 11, and the centrifugal force Under the effect of throwing off powder, the dust in the powder throwing tank 24 is thrown out from the powder throwing gap 27 to the outside.

[0055] All the other parts are identical with embodiment 1.

Embodiment 3

[0057] like Figure 8 , Figure 9 as shown,

[0058] The powder rejection groove 24 is a concave groove located at the upper end of the swivel 11, and no vibration beads 25 are added in the powder rejection groove 24.

[0059] Described swivel 11, outer circle side is provided with air hole 28, and air hole 28 is communicated with powder throwing tank 24, when being convenient to shut down maintenance and repair, blows out the dust settled in the powder throwing tank 24 with air.

[0060] The swivel 11 is a sedimentation ring. The sedimentation ring is formed by round steel through lathe, milling machine, drilling machine, etc. The upper part of the inner circular surface of the sedimentary ring is provided with a positioning ring 13 installation position, and the lower part of the inner circular surface is provided with a reverse flow ring 10 installation position. , the lower end surface of the inner circle is provided with evenly distributed locking through holes connecte...

Abstract

The invention discloses a vibration bead type maze dust-proof grinding roller device. The device comprises a shaft, a supporting assembly, a dust-proof assembly and a transmission assembly, wherein the supporting assembly, the dust-proof assembly and the transmission assembly sequentially sleeve on the shaft from top to bottom; the dust-proof assembly comprises a maze static ring, a maze moving ring and a rotating ring; the rotating ring is fixed to the upper end surface of a bearing sleeve of the transmission assembly, a counter-current ring is arranged in the middle of the inner ring of therotating ring, a step is arranged at the upper part of the inner ring of the rotating ring, a positioning ring is arranged on the step, and the maze moving ring is arranged on a throwing ring; and themaze static ring is arranged above the maze moving ring and is matched with the maze moving ring, a plurality of layers of maze gaps are formed between the matching surfaces, vibration beads are arranged in the maze gaps, a powder throwing groove is formed between the lower end surface of the maze moving ring and the upper end surface of the rotating ring, a leakage hole is formed in the lower end surface of the maze moving ring, one end of the leakage hole is in communication with the maze gaps, and the other end of the leakage hole is in communication with the powder throwing groove. The device has the advantages that the dust-proof effect is good, the repair and maintenance cost in the operation of a raymond mill and vertical mill grinding roller device is reduced, and the production efficiency of enterprises is improved.

Description

technical field [0001] The invention relates to the technical field of dust-proof seals on the oil level of output shafts in the manufacture of mechanical equipment, in particular to a vibrating bead-type labyrinth dust-proof grinding roller device in Raymond mills and vertical mills. Background technique [0002] Raymond mill and vertical mill are widely used grinding equipment, which are widely used in the high-fine powder processing of more than 280 kinds of materials in mineral, chemical, construction and other industries. However, the output shaft seals of gearboxes, blowers, analyzers, motors, central shafts, and balers in Raymond mills and vertical mills are easy to enter powder and jam the bearings. In particular, the shaft seals in the grinding roller devices of Raymond mills and vertical mills are prone to powder feeding and jamming, causing the grinding rollers in the grinding roller devices to drag and slide, and failure to find out in time will cause the grindin...
