Abstract
The utility model relates to an air pressure supplement type sealing device for the feed part of a wet ball mill, which is composed of an air bored elastic tube which is arranged in the seam between a feed elephant trunk and the feed part. The elastic tube is nested on the exterior of the feed elephant trunk, with one end fixed on the elephant trunk and the other end contacted with the feed part. The utility model has beneficial effects that the structure is simple and the cost is low; the leaking problems caused by inverse splashes and inverse flows are effectively restrained; the quantity of the sealing medium and the medium packing for replacement is reduced; the cost of the consumable is saved; and the utility model is particularly applied to the wet ball mill, and is also applied to the liquid sealing problems on other machines. The utility model is easy to be popularized.
Description
(1) technical field
The utility model relates to the sealing device to liquid, particularly a kind of wet ball mill pan feeding portion air pressure compensation type sealing device that can prevent that wet ball mill pan feeding portion slurries from revealing.
(2) background technology
The leak of liquid at wet ball mill pan feeding position is a technical barrier always, and the leakage of ball mill has brought very big trouble to workshop hygiene, and has caused the waste of material.
(3) summary of the invention
The utility model provides a kind of wet ball mill pan feeding portion air pressure compensation type sealing device that can prevent that wet ball mill pan feeding portion slurries from revealing in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
Wet ball mill pan feeding of the present utility model portion air pressure compensation type sealing device, its special character is: be made up of elastic tube seam crossing, that have air admission hole between pan feeding elephant trunk and pan feeding portion, elastic tube is socketed in pan feeding elephant trunk outside, and an end is fixed on the pan feeding elephant trunk, and the other end contacts with pan feeding portion.Under the expansion of air pressure, the elastic tube end is pressed in the pan feeding portion, and integral sealing is good.
Wet ball mill pan feeding of the present utility model portion air pressure compensation type sealing device, an end of elastic tube is fixed on the pan feeding elephant trunk by flange, good seal.
Wet ball mill pan feeding of the present utility model portion air pressure compensation type sealing device, described elastic tube is a bellows, can adopt elastic wear-resisting rubber to make, and makes sealing effectiveness better, and is difficult for deformed damaged.
Principle of the present utility model is to remedy the slit of sealing medium generation and the gap that long term wear causes, the leakage problem that the backflow of restriction slurries causes with constant air pressure.
The beneficial effects of the utility model are, the simple structure compactness, cost is low, the leakage problem that suppressed the grinding machine splash greatly, refluxes and cause, reduce the quantity that sealing medium, medium packing are changed, saved the consumptive material expense, be highly suitable for wet ball mill, also be applicable on other machine the sealing problem of liquid is easy to promote the use of.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 pan feeding elephant trunk, 2 air admission holes, 3 bellowss, 4 sealing mediums, 5 sealing clamps, 6 pan feeding portions.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Wet ball mill pan feeding of the present utility model portion air pressure compensation type sealing device, form by bellows 3 seam crossing between pan feeding elephant trunk 1 and pan feeding portion 6, that have air admission hole 2, bellows is socketed in pan feeding elephant trunk outside, and an end is fixed on the pan feeding elephant trunk by flange, the sealing clamp 5 of the other end and pan feeding portion 6 is close to, and integral sealing is good.Bellows can adopt elastic wear-resisting rubber to make, relying on atmospheric pressure makes the bellows elongation be close to sealing clamp, and the contact site precision processing of sealing clamp, improve the seal of the contact-making surface between bellows 3 and the sealing clamp 5, make integral sealing good, and can prevent that the bellows contact site is worn.
Wet ball mill pan feeding of the present utility model portion air pressure compensation type sealing device is mainly used in wet ball mill pan feeding position, and is applicable to the pan feeding position of other all ball mills.The parts that form air pressure are bellows 3, and the one end is fixed on an end of pan feeding elephant trunk 1, and the sealing clamp 5 of the other end and pan feeding portion 6 is close to.Inflate in bellows 3 from air admission hole 2, bellows can stretch under the effect of certain air pressure, make bellows and sealing clamp 5 be in tight contact condition all the time, and do not influence relatively rotating of pan feeding portion and pan feeding elephant trunk, the air pressure that forms can be blown into backflow and the seepage that pan feeding portion inner barrel stops the liquid that the cylindrical shell rotation causes by the slit between sealing medium 4 and the pan feeding elephant trunk, with this leakage that comes slit of compensation sealing medium generation to be caused.
Claims (3)
1. wet ball mill pan feeding portion air pressure compensation type sealing device, it is characterized in that: form by elastic tube seam crossing, that have air admission hole (2) that is positioned between pan feeding elephant trunk (1) and the pan feeding portion (6), elastic tube is socketed in pan feeding elephant trunk outside, and an end is fixed on the pan feeding elephant trunk, and the other end contacts with pan feeding portion.
2. wet ball mill pan feeding according to claim 1 portion air pressure compensation type sealing device, it is characterized in that: an end of elastic tube is fixed on the pan feeding elephant trunk by flange.
3. wet ball mill pan feeding according to claim 1 and 2 portion air pressure compensation type sealing device, it is characterized in that: described elastic tube is bellows (3).
