Abstract
The invention provides a self-pressing type spring sealing system of a ball mill. The self-pressing type spring sealing system comprises a static sealing ring and a dynamic sealing device matched with the static sealing ring, and is characterized in that the static sealing ring is bonded on a pressing plate; when the static sealing ring is abraded and a roller of the ball mill moves in parallel, a lateral pressing plate moves inwards and a gap generated by the abrasion in the static sealing ring can be automatically compensated, so that the sealing performance is kept. The sealing system provided by the invention has good wear resistance and good sealing performance, is long in service life and is convenient to maintain; and the negative pressure in the ball mill is stable and materials are prevented from being overflowed, so that a production environment is effectively improved and the production efficiency of the ball mill is improved.
Description
Technical field
The spring sealed system of a kind of ball mill self-pressing type involved in the present invention, mainly comprises static sealing ring and dynamic sealing device composition.
Technical background
Ball mill is widely used in the industry fields such as metallurgy, coal, building materials, and in the use procedure of ball mill, the cylinder circumferential movement of ball mill, the interface of cylinder and drawing mechanism is difficult to seal.Prior art adopts felt and the sealing of side angle plate.Shortcoming is that seal is poor, and easy to wear, service life is short, the gap produced because of wearing and tearing, and cause negative pressure in ball mill unstable, abrasive material leaks seriously, and production environment is poor, and seal is changed loaded down with trivial details, and the operating efficiency of ball mill is low.
Summary of the invention
In order to overcome the defect that prior art exists, the object of the present invention is to provide the spring sealed system of a kind of ball mill self-pressing type, comprise static sealing ring, its thickness is 3 ~ 6cm, width is 5 ~ 8cm, material is tetrafluoroethene, felt, one in graphite packing or immersion oil packing, dynamic sealing device, it consists of side guide, hydraulic spring grease cup and fixed support, wherein the material of side guide is stainless steel, ABS, one in POM or bakelite, its specification is identical with static sealing ring, side guide is fixed 30 ~ 50 hydraulic spring grease cups, top nut is connected with fixed support.Fixed support is parallel with side guide, adjusting nut can adjust gap between static sealing ring and dynamic sealing device and compression degree, when static sealing ring wearing and tearing and cylinder are put down to motion, side guide moves inward automatically can the gap that produces because of wearing and tearing of auto-compensation static sealing ring, thus keeps its sealing.Apply sealing system of the present invention, there is wear-resisting, good airproof performance, reach 5 ~ 10 years service life, easy to maintenance, negative regulation in ball mill, excessive without material, effectively improve production environment, be conducive to again the operating efficiency improving ball mill.
The present invention obtains successful Application in Nanjing hundred Mei Su industry Co., Ltd at present.

Concrete invention example:
In order to understand the present invention better, describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, ball mill self-pressing type spring seal unit, comprise static sealing ring (1), its thickness is 3 ~ 6cm, and width is 5 ~ 8cm, dynamic sealing device, it consists of side guide (2), hydraulic spring grease cup (3) and fixed support (4), wherein side guide specification is identical with static sealing ring, and side guide is fixed 45 hydraulic spring grease cups, and top nut is connected with fixed support.Nanjing hundred Mei Su industry Co., Ltd application verification, in ball mill work production, occur without flash phenomena, improve production environment, service life has made a call to 8 years.
Although detail the present invention with preferred embodiment, but it is not intended to limit the present invention.Any those skilled in the art, without departing from the spirit and scope of the present invention, should make various amendment and change.Therefore protection scope of the present invention should be considered as appended claims limited range.
Claims (2)
