Abstract
The utility model discloses a spiral paddle in a vacuum pug mill. The spiral paddle in the vacuum pug mill is characterized by comprising a rotation shaft and rotation vanes. Non-continuous segments, a continuous segment and a head part are sequentially and integrally arranged on the rotation shaft. The non-continuous segments are fixedly provided with non-continuous rotation vanes. The continuous segment is fixedly provided with continuous rotation vanes. The head part is of a cone-shaped structure. The cone-shaped structure gradually reduces from the non-continuous segments to the continuous segment and moreover, and at least two non-continuous rotation vanes are arranged on the head part and evenly distributed on the periphery of the head part. Traditionally, a rotation shaft is provided with one type of rotation vanes, however, the continuous rotation vanes and the non-continuous rotation vanes are arranged on the rotation shaft according to the spiral paddle in the vacuum pug mill. Pug can be smoothly and rapidly conveyed and stirred, and good vacuum pumping degree is achieved. As the structure of the head part is improved, the pug at the head part can be evenly stressed and the phenomenon that the pug loosens at the center can be effectively removed.
Description
Technical field
The utility model relates to a kind of forming process of ceramics machinery field, and more particularly, it relates to the screw in a kind of vacuum deairing machine.
Background technology
Vacuum deairing machine is used as the preparation and the degassing machinery of plastic mud material, in the forming process of ceramics preparation process, contain defectives such as bubble for each component skewness of eliminating the filter press mud cake is even, generally be pug to be processed with vacuum deairing machine, pug is after the vacuum pugging machined, the distribution of each component is tending towards evenly, and structure is dense, and the plasticity and the dry tenacity of pug all increase.
Pug conveying device in the vacuum deairing machine is made of continuous type screw and the oval mud cylinder of pressing usually, perhaps is made of discontinuous type screw and comb plate.Wherein screw has included rotating shaft and rotating vane, whether is divided into continuous type screw and discontinuous type screw continuously according to rotating vane.The advantage of continuous type screw is to carry pug freely, and vacuum chamber is difficult for stopping up, and shortcoming is to have increased the sealing difficulty of pressing mud drum shaft place, keeps in repair cumbersome; The advantage of discontinuous type screw is the volume that has increased vacuum chamber, and the pug time of staying is longer, pug is stirred to reach vacuumize degree preferably, and relatively simple for structure, easy to maintenance, shortcoming is to cause obstruction easily.The two ends end to end of rotating shaft are plane, and this structure makes that the pug that is in the center is stressed inadequately evenly, too loose when stirring at pug and carrying.
Summary of the invention
Deficiency at the prior art existence, the purpose of this utility model is to provide the screw in a kind of vacuum deairing machine, this screw not only can carry pug freely, pug is stirred to reach vacuumize degree preferably, and can make the pug at each position all stressed evenly.
For achieving the above object, the utility model provides following technical scheme: the screw in a kind of vacuum deairing machine, comprise rotating shaft and rotating vane, the discontinuous segment of described rotating shaft for being wholely set successively, continuous segment and head, described discontinuous segment is installed with discontinuous type rotating vane, described continuous segment is installed with the continuous type rotating vane, described head is the conical structure setting, the direction diameter of this conical structure along discontinuous segment to continuous segment reduces gradually, and head is provided with two discontinuous rotating vanes at least, and the discontinuous rotating vane of head evenly distributes along the circumferencial direction of head.
By adopting technique scheme, a traditional rotating shaft is provided with a kind of rotating vane to change to continuous type rotating vane and discontinuous type rotating vane is set on the rotating shaft simultaneously, just realized to carry pug freely, pug is stirred also can reach vacuumized degree preferably; The architecture advances of head, the pug that can guarantee to be in head position is stressed evenly, effectively eliminates the loose phenomenon of center pug.
The utility model further is set to: described interior of rotating shaft is provided with the shock suction layer that elastomeric material supports.
By adopting technique scheme, screw of the present utility model is by being provided with a shock suction layer, when screw because of cooperating inaccurate or when running into hard thing, can producing the effect of shock-absorbing by shock suction layer, screw can be damaged because of vibrations.
The utility model further is set to: the outer surface of described rotating vane all is welded with hard alloy layer, and described hard alloy layer is the W-Co kind carbide alloy.
By adopting technique scheme, on the surface of rotating vane hard alloy layer is set, can prolong the use service life of screw, the abrasion resistance that increases screw, attenuating maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the screw embodiment in the utility model vacuum deairing machine.
The specific embodiment
With reference to Fig. 1 the screw embodiment in the utility model vacuum deairing machine is described further.
Screw in a kind of vacuum deairing machine, comprise rotating shaft 1 and rotating vane 2, the discontinuous segment 11 of described rotating shaft 1 for being wholely set successively, continuous segment 12 and head 13, described discontinuous segment 11 is installed with discontinuous type rotating vane 21, described continuous segment 12 is installed with continuous type rotating vane 22, described head 13 is the conical structure setting, 12 direction diameter reduces this conical structure gradually along discontinuous segment 11 to continuous segment, and head 13 is provided with two discontinuous rotating vanes 23 at least, and the discontinuous rotating vane 23 of head 13 evenly distributes along the circumferencial direction of head 13.
By adopting technique scheme, a traditional rotating shaft 1 is provided with a kind of rotating vane to change to continuous type rotating vane 22 and discontinuous type rotating vane 21 is set on the rotating shaft 1 simultaneously, just realized to carry pug freely, pug is stirred also can reach vacuumized degree preferably; The architecture advances of head 13, the pug that can guarantee to be in head 13 positions is stressed evenly, effectively eliminates the loose phenomenon of center pug.
Described rotating shaft 1 inside is provided with the shock suction layer 3 that elastomeric material supports.
By adopting technique scheme, screw of the present utility model is by being provided with a shock suction layer 3, when screw because of cooperating inaccurate or when running into hard thing, can producing the effect of shock-absorbing by shock suction layer 3, screw can be damaged because of vibrations.
The outer surface of described rotating vane all is welded with hard alloy layer 4, and described hard alloy layer 4 is the W-Co kind carbide alloy.
By adopting technique scheme, on the surface of rotating vane 2 hard alloy layer 4 is set, can prolong the service life of screw, the abrasion resistance that increases screw, attenuating maintenance cost.
