Description

Sealing disc of ceramsite rotary kiln

Technical Field

The utility model belongs to haydite rotary kiln equipment field, concretely relates to haydite rotary kiln sealed dish.

Background

The haydite rotary kiln is a special device in haydite production, because the relative rotation of big kiln barrel and small kiln barrel is caused by the asynchronous rotation of big kiln barrel and small kiln barrel, therefore the sealing problem is difficult to solve, when the rotary kiln runs, because the inside high temperature produces very big atmospheric pressure, causes the internal dust of kiln to overflow easily, for guaranteeing that the operation environment is clean, the sealing performance requirement is higher.

The existing rotary kiln has large volume and diameter, the sealing of the kiln body can be influenced when the kiln body generates small radial runout and axial runout during rotation, so that material, dust and gas are leaked, and a single sealing mode cannot meet higher sealing requirements generally.

Common contact seals are scale seals and friction plate seals. Although the scale type sealing device has a simple structure, the scale is seriously abraded due to no lubrication, and the sealing effect is influenced; the friction type seal generally uses lubricating oil to lubricate the friction plate, the pipeline is complex, the lubricating oil is easy to evaporate and run off in the environment with higher temperature, the lubrication is insufficient, the abrasion of the friction plate is accelerated, the lubricating material is wasted, and the environment is influenced.

Common non-contact seals are labyrinth seals and pneumatic seals. Non-contact seals all suffer from the same problem: the cylinder body and the sealing structure are not contacted with each other, and the reserved gap is large.

SUMMERY OF THE UTILITY MODEL

To the technical problem who exists among the prior art, the utility model aims to provide a haydite rotary kiln sealed dish, in order to realize above-mentioned purpose, the utility model discloses the technical scheme who adopts does:

the utility model provides a haydite rotary kiln sealed dish, includes kiln barrel and little kiln barrel, kiln barrel and the butt joint of little kiln barrel tip insert, kiln barrel and little kiln barrel tip fixed respectively in surface are equipped with sealed dish, the fixed sealed dish sealing base that is equipped with on the sealed dish, inside cavity and the one end opening of sealed dish sealing base, the inside spring that is equipped with of sealed dish sealing base, spring one end is connected with the movable block, the movable block opposite side is equipped with sealed dish seal, sealed dish seal stretch out sealed dish sealing base's open end and with sealed dish sealing contact.

Preferably, the sealing discs on the end surfaces of the large kiln cylinder body and the small kiln cylinder body are arranged oppositely up and down.

Preferably, the sealing disc on the end surface of the kiln cylinder body is vertically fixed with the outer cover.

Preferably, the seal disk seal is a fibrous blanket.

Preferably, the sealing plate sealing base is several in number.

The utility model provides a pair of haydite rotary kiln sealed dish through setting up sealed dish, sealed dish sealing base and sealed dish body, has solved the contactless of each other between big kiln barrel and the little kiln barrel, and it is great to reserve the gap, leaks out and leaks the serious problem of material, and sealed dish body and sealed dish contact inseparable can be ensured in the setting of spring, has solved the relatively poor problem of sealed effect.

FIG. 2 is a partial enlarged view of a sealing disc A of the ceramsite rotary kiln of the present invention;

in the figure, 1, a large kiln cylinder body 2, a small kiln cylinder body 3, a sealing disc 4, a sealing disc sealing base 5, a sealing disc sealing body 6, a spring 7, a moving block 8 and an outer cover are arranged

Detailed Description

For further description, the sealing disc of the ceramsite rotary kiln of the present invention is further described with reference to the accompanying drawings.

In FIGS. 1-2: the utility model provides a haydite rotary kiln sealed dish, includes kiln barrel 1 and little kiln barrel 2, kiln barrel 1 and 2 tip butt joints of kiln barrel insert, kiln barrel 1 and 2 barrel tip surfaces of kiln barrel are fixed respectively and are equipped with sealed dish 3, sealed dish 3 is gone up the fixed sealed dish sealing base 4 that is equipped with, sealed dish sealing base 4 inside cavity and one end opening, sealed dish sealing base 4 inside is equipped with spring 6, spring 6 one end is connected with

movable block

7, 7 opposite sides of movable block are equipped with sealed dish seal 5, sealed dish seal 5 stretch out sealed dish sealing base 4 the open end and with sealed 3 sealing contact.

The sealing discs 3 on the end surfaces of the large kiln cylinder body 1 and the small kiln cylinder body 2 are arranged oppositely up and down.

The sealing disc 3 on the end surface of the kiln cylinder body 1 is vertically fixed with an outer cover 8.

The sealing disc sealing body 5 is a fiber blanket.

The number of the sealing plate sealing bases 4 is several.

The working principle is as follows: after starting the big kiln of rotary kiln, relative rotation takes place for big kiln barrel and little kiln barrel, and the sealed dish on big kiln barrel and the little kiln barrel also correspondingly takes place relative rotation, through adjusting sealed dish sealing base spring, sealed dish seal remains throughout with the laminating of sealed dish in the rotation process.

The foregoing is illustrative and explanatory of the inventive concept, and is not exhaustive or exhaustive, as is known in the art, and various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as defined in the claims.
