ル９に連通ずるラビリンス状の油脂室１１とから成る。The shaft sealing device of the mixer shown in the figure consists of a sleeve 3 fitted on the outer periphery of a stepped portion of a rotating mixing shaft 1 of different diameters that protrudes outside the mixing tank, and a sleeve 3 on the inside 13 side of the mixing tank. A removable circular seal plate 4 is fixed to a flange formed at the end of the mixing tank by bolts 5 and is substantially flush with the inner surface of the vertical wall 2 of the mixing tank, and is inserted into the outer periphery of the sleeve 3, A sliding ring unit 6 consisting of two separate sliding/moving rings 6b, 6b' and O-rings 6a, 6a', which can be divided into two, is fixed to the vertical wall 2 of the mixing tank by bolts 8, and has a lubricating nipple. 9 and 10 and sealingly holds the sliding ring unit; a substantially rectangular oil chamber 12 in which the sliding ring unit 6 is mounted between the holding ring 7 and the sleeve 3; From a labyrinth-shaped oil chamber 11 that has two vertical parts and two horizontal parts formed at the boundary between the vertical wall 2 of the tank, the flange part of the sleeve 3, and the seal plate 4, and communicates with the oil nipple 9. Become.
スリーブ３のフランジ部の裏面側は凹部状に形成されて
おり、該凹部内に滑動リング６ｂと０−ＩＪフンギａと
が嵌入されて回転部を形成している。The back side of the flange portion of the sleeve 3 is formed into a recess, and a sliding ring 6b and an 0-IJ ring gear a are fitted into the recess to form a rotating portion.
又、保持リング７の内側の凹部には滑動リング６ｂ’と
Ｏ−リング６ａ′とが嵌入されており、これによって静
止部が形成されている。Furthermore, a sliding ring 6b' and an O-ring 6a' are fitted into the recessed portion inside the retaining ring 7, thereby forming a stationary portion.
そしてスリーブ３、シール板４及び滑動リングユニット
６は混合軸１に固定されているので回転混合軸１と共に
回転し。Since the sleeve 3, seal plate 4, and sliding ring unit 6 are fixed to the mixing shaft 1, they rotate together with the rotating mixing shaft 1.
保持リング７と混合槽の垂直壁２は静止している３ラビ
リンス状の油脂室１１は図中では細溝状で表わされてい
るが、実際には円周状に伸びている。The retaining ring 7 and the vertical wall 2 of the mixing tank are stationary.3 The labyrinth-shaped fat chamber 11 is shown as a narrow groove in the figure, but in reality it extends circumferentially.
又、油脂室１１の一方は混合槽内部１３に連通し、他方
は滑動リングユニット６に連通している。Further, one side of the oil chamber 11 communicates with the inside of the mixing tank 13, and the other side communicates with the sliding ring unit 6.
さらに油脂室１２は保持リング７とスリーブ３の間で、
この油脂室１２の外側に若干の隙間が設けてあり、これ
によって外部へ通じる構造としている。Furthermore, the oil chamber 12 is located between the retaining ring 7 and the sleeve 3.
A slight gap is provided on the outside of this oil/fat chamber 12, which allows the oil chamber 12 to communicate with the outside.
なお、本軸封装置は主として混合槽内部の混合物が外部
へ流出するのを防止する役目のものであって、回転混合
軸１にか５る軸荷重はこの軸封装置の外側に別個に設け
た軸受により支持されている。Note that this shaft sealing device mainly serves to prevent the mixture inside the mixing tank from flowing out to the outside, and the shaft load on the rotating mixing shaft 1 is provided separately on the outside of this shaft sealing device. It is supported by a bearing.
上記構成によって、滑動リングユニット６の滑動リング
６ ｂ 、 ６ ｂ’は図中に示すように相互に向い合
っているその研摩面を介して摺動し、かつ主として油脂
室１２の油脂膜により摩擦の少ない運動を相互に浮動状
態で行なっている。With the above configuration, the sliding rings 6 b and 6 b' of the sliding ring unit 6 slide through their polished surfaces facing each other as shown in the figure, and are mainly caused by friction due to the oil film in the oil chamber 12. They perform movements with little movement in a mutually floating state.
混合槽内部に通じる油脂室１１はラビリンス状に形成さ
れているので、油脂室内の流体抵抗が大きく該油脂室内
全体に油脂を充填するには比較的高い圧力を必要とする
。Since the oil chamber 11 communicating with the inside of the mixing tank is formed in a labyrinth shape, the fluid resistance within the oil chamber is large and a relatively high pressure is required to fill the entire oil chamber with oil.
これとは反対に、油脂室１２は矩形断面であり、注油ニ
ップル１０と直結した簡単な構造であるから該油脂室１
２内に油脂を充填するのに高い圧力は必要としない。On the contrary, the oil chamber 12 has a rectangular cross section and has a simple structure that is directly connected to the oil nipple 10.
No high pressure is required to fill the interior of the container with oil or fat.
従って、油脂室１２に必要な圧力よりも油脂室１１に必
要な圧力の力が高い圧力を必要とする。Therefore, the pressure required for the oil chamber 11 is higher than the pressure required for the oil chamber 12.
油脂室１２に必要な圧力がそれ程高い圧力である必要が
ないため、保持リング７とスリーブ３の間の隙間から油
脂が洩れ出るということは生じない。Since the pressure required in the oil chamber 12 does not need to be very high, oil does not leak out from the gap between the retaining ring 7 and the sleeve 3.
注油ニップル９により油脂室１１に油脂が注入されると
、油脂はシール板４と混合槽の垂直壁２の間の部分に充
填され、ある程度は混合槽内部１３にも洩出する。When oil is injected into the oil chamber 11 by the oil filling nipple 9, the oil fills the area between the seal plate 4 and the vertical wall 2 of the mixing tank, and leaks to some extent into the inside 13 of the mixing tank.
従って、シール板４と混合槽の垂直壁２の間で望ましく
ない摩耗作用が働らくのを避けることができるという利
点が得られる。The advantage thus obtained is that undesirable abrasive effects between the sealing plate 4 and the vertical wall 2 of the mixing vessel can be avoided.
該摩耗作用は長期間経過すると機械部品の非常に不都合
な、かつ高い摩滅となるからである。This is because, over a long period of time, this abrasive effect results in very disadvantageous and high wear of the mechanical parts.
さらに、混合槽内部１３で成牛される乳状セメントの混
和液がラビリンス状の油脂室１１に侵入しようとしても
、注油ニップル９で油脂室１１内□の圧力を適当に保っ
ておけば侵入しないし、又仮りに侵入しても注油ニップ
ル９でこの油脂室内の圧力を高めると、これらを容易に
混合槽内部１３に押し戻すことができる。Furthermore, even if the milky cement mixture grown in the mixing tank 13 tries to enter the labyrinth-shaped oil chamber 11, it will not invade if the pressure in the oil chamber 11 is maintained at an appropriate level with the oil nipple 9. Even if they do get in, by increasing the pressure inside the oil chamber with the oil nipple 9, they can be easily pushed back into the mixing tank interior 13.
さらに、回転中は混合槽の垂直壁２とシール板４との間
の隙間に充填されている油脂に回転による遠心力が作用
し、混和液が油脂室１１に侵入するのを防止し、これを
押し戻すことができる。Furthermore, during rotation, centrifugal force due to the rotation acts on the oil and fat filled in the gap between the vertical wall 2 and the seal plate 4 of the mixing tank, preventing the mixed liquid from entering the oil and fat chamber 11. can be pushed back.
円筒状の油脂室１２に連通ずる注油ニップル１０によっ
て該油脂室内の圧力を適当に保ち、これによって該油脂
室内に発生した汚染油脂を排出したり、又外部から水や
微小固形物が侵入してもスリーブ３と保持リング７との
間の微小な隙間からこれを容易に外部へ排出したりする
ことができる。A lubrication nipple 10 communicating with the cylindrical oil chamber 12 maintains the pressure inside the oil chamber appropriately, thereby draining contaminated oil and fat generated in the oil chamber and preventing water and minute solids from entering from the outside. This can also be easily discharged to the outside through the minute gap between the sleeve 3 and the retaining ring 7.
又、油脂室１１によって混合物が滑動リングシール６へ
直接接触することが遮断されているため、油脂室１２へ
の油脂の供給は比較的長い時間々隔て行なうことができ
る。Also, since the mixture is blocked from direct contact with the sliding ring seal 6 by the oil chamber 11, oil can be supplied to the oil chamber 12 at relatively long intervals.
