Abstract

The utility model discloses a sealing device, used for the rotary parts of the horizontal roller mill, which comprises a labyrinth ring(1), a labyrinth ring(1), a connecting board, a V shaped rubber sealing ring(1), a V shaped rubber sealing ring(2). The connecting board is internally provided with two V shaped rubber sealing rings in the radial direction, and the labyrinth ring(1) is internally provided with an oiling pipe. When working, the utility model infuses the lubricating oil in the static and non rotating labyrinth ring(1), forming oil seal between the labyrinth ring(1) and the labyrinth ring (2), and forming an independent sealed lubricating area with the V shaped rubber sealing ring(1) and the V shaped rubber sealing ring(2) in the connecting board, so as to guarantee the flexible movement of the rotary parts. Meanwhile, the oil film is prevented from overflow, and the external air dust can be prevented from entering into the equipment, thereby guaranteeing the cleanness of the equipment.

Description

A kind of seal arrangement that is used for crouching between the roller mill sound revolving part

Technical field

The utility model relates to a kind of seal arrangement, particularly a kind of seal arrangement that is used for crouching between the roller mill sound rotational structure spare.

Background technique

Everybody known sealing technique adopts V-type seal with elastometic washer or labyrinth seal mostly at present, but because this class sealing configuration is simple, sealability is relatively poor, generally only is applicable to static sealing.When the roller grinder that crouches is done, material by cylindrical shell extruding, material and material mutual extrusion process in splash phenomena, air-flow instability, and great majority crouch that to relate to a structural member static for sealing on the roller mill, the problem that another structural member rotates.So this simple in structure, seal arrangement that sealability is relatively poor can not satisfy the seal request that crouches between the roller mill sound rotational structure spare far away, easily causes inner flour dust overflow, the invasion of outside dust, oil leak befouling environment etc.

Summary of the invention

Particularity when doing at the roller grinder that crouches, the utility model provide a kind of seal arrangement that is used for crouching between the roller mill sound rotational structure spare, and it can not only be controlled material and be difficult for leakage, guarantees sealing, and simple in structure, reliable.

The technological scheme that the utility model adopted is: assembled by labyrinth ring (), labyrinth ring (two) and connecting plate, twice V-arrangement rubber seal radially is installed in the connecting plate, have oil filler pipe in the labyrinth ring ().Form sealing area between twice V-arrangement rubber seal and two labyrinth rings, fill with lubricant oil during proper functioning in the sealing area.

The beneficial effects of the utility model are: can prevent effectively that not only outside dust from invading and lubricating oil viscosity is formed the rotation that piece influences revolving part, more can prevent the excessive of inner dust and lubricant oil and befouling environment.

Description of drawings

The utility model is described in further detail below in conjunction with Figure of description and embodiment.

Fig. 1 is a structural representation of the present utility model.

Among Fig. 1: 1. supporting part, 2. labyrinth ring (), 3. labyrinth ring (two), 4. oil filler pipe, 5. bolt (), 6. connecting plate, 7.V type rubber seal (), 8.V type rubber seal (two), 9. bolt (two).

Embodiment

As shown in Figure 1, labyrinth ring () 2 is connected by bolt (two) 9 and roller for sleeping in mill supporting portion 1, does not staticly relatively rotate, and 6 of labyrinth rings (two) 3, connecting plate are connected with cylindrical shell by bolt () 5, rotate together.Labyrinth ring (one) 2 has oil filler pipe 4, and V-type rubber seal () 7 and V-type rubber seal (two) 8 radially are installed in the connecting plate 6.

When the roller grinder that crouches is done, lubricant oil is annotated in the oil filler pipe 4 of into static non-rotary labyrinth ring () 2, so form oil sealing between labyrinth ring () 2, the labyrinth ring (two) 3, and and connecting plate 6 in V-type rubber seals () 7 and V-type rubber seal (two) 8 form an independent sealed regions of lubrication together, to guarantee the flexible operation of revolving part.Stop that simultaneously oil film is excessive, and outside airflow dust can't be invaded also in the equipment, has guaranteed the spatter property of equipment.

Claims

1. seal arrangement that is used for crouching between the roller mill sound revolving part, it comprises: labyrinth ring (), labyrinth ring (two), connecting plate, V-type rubber seal (), V-type rubber seal (two), it is characterized in that: V-type rubber seal () and V-type rubber seal (two) radially are installed in the connecting plate, have oil filler pipe in the labyrinth ring ().
