Abstract
The utility model discloses a rotary expansion compensation device on an inlet and exhaust pipe in a coal material decomposition rotary kiln. The device comprises two sealing parts, wherein one sealing part is arranged on a position where a kiln head and a rotating part of the inlet and exhaust pipe are contacted, and the other sealing part is arranged between the rotating part and the non-rotating part of the inlet and exhaust pipe; the end part of the rotating part of the inlet and exhaust pipe is arranged in a position where the non-rotating part is connected with the rotating part; simultaneously the end part of the rotating part of the inlet and exhaust pipe is arranged in a position which is connected with the non-rotating part, thereby well solving the axial movement problem caused by expansion on heating and contraction on cooling of the inlet and exhaust pipe; and the air in and out of fixed parts is not affected. Pressing plates movably connected with graphite packings are arranged on the external periphery of the inlet and exhaust pipe; the pressing plates are movably connected with fixed bulges by bolts; and the mode of the bolt connection is convenient for mounting, overhaul and dismounting.
Description
Technical field
The utility model belongs in the large-scale heating kiln body supplementary equipment technical field that adds, and is specifically related to turn round on the air inlet-outlet pipe in a kind of coal substance decomposition rotary kiln the expansion compensation device.
Background technique
Coal substance decomposition kiln body has various ways, more horizontal rotary kiln body, the air inlet-outlet pipe of the outer mechanism connection of setting and kiln in the rotary kiln body, the part of air inlet-outlet pipe in kiln rotated with the kiln body, be connected with other mechanisms after stretching out the kiln body, just can have no longer rotated with the kiln body.The problem that has several needs to overcome between this, one is the rotary seal problem between revolution kiln hood and air inlet-outlet pipe, the 2nd, the air inlet-outlet pipe rotating part and the relative rotary seal problem of rotating part not, the 3rd, the problem of expanding with heat and contract with cold and bringing of air inlet-outlet pipe self.
The model utility content
At above-mentioned several problems, the utility model provides that a kind of sealing effect is splendid, revolution expansion compensation device on the air inlet-outlet pipe in the coal substance decomposition rotary kiln of long service life, use said apparatus can solve the rotary seal problem of turning round between kiln hood and air inlet-outlet pipe, the air inlet-outlet pipe rotating part and the relative rotary seal problem of rotating part not, the problem of expanding with heat and contract with cold and bringing of air inlet-outlet pipe self.
Revolution expansion compensation device on the air inlet-outlet pipe in a kind of coal substance decomposition rotary kiln, comprise the sealed member that is arranged on kiln hood and the air inlet-outlet pipe rotating part contact position, also comprise air inlet-outlet pipe rotating part and the sealed member between the rotating part not, the end of described air inlet-outlet pipe rotating part is arranged on not within the rotating part and rotating part connection part, sealed member between described air inlet-outlet pipe rotating part and the kiln hood comprises seal ring district and the fixed lobe with kiln hood end face one, described seal ring is provided with the graphite packing in the district, the pressing plate that flexibly connects with described graphite packing is set on the excircle of described air inlet-outlet pipe rotating part, and described pressing plate and described fixed lobe flexibly connect by bolt; Described air inlet-outlet pipe rotating part and not the sealed member between the rotating part comprise and air inlet-outlet pipe not the seal ring district and the fixed lobe of rotating part one, described seal ring is provided with the graphite packing in the district, the pressing plate that flexibly connects with described graphite packing is set on the excircle of described air inlet-outlet pipe, and described pressing plate and described fixed lobe flexibly connect by bolt.
On the bolt of described connection pressing plate and fixed lobe resilient pad is set.
After compressing, described connection pressing plate and fixed lobe have the gap between the two.
Because the rotary seal mechanism between the utility model revolution kiln hood and air inlet-outlet pipe, it comprises the sealed member that is arranged on kiln hood and the air inlet-outlet pipe rotating part contact position, also comprise air inlet-outlet pipe rotating part and the sealed member between the rotating part not, sealed member comprises and not the seal ring district and the fixed lobe of rotating part one, described seal ring is provided with the graphite packing in the district, can solve the problem of high temperature rotary seal well.Simultaneously the end of air inlet-outlet pipe rotating part be arranged on rotating part connection part not within, can solve expanding with heat and contract with cold of air inlet-outlet pipe self well and bring axial float, and not influence gas turnover effect.The pressing plate that flexibly connects with described graphite packing is set on the excircle of described air inlet-outlet pipe, described pressing plate and described fixed lobe flexibly connect by bolt, bolted mode is convenient to install, maintenance and dismounting, on described connection pressing plate and the fixed lobe bolt resilient pad is set, can further improve the degree that compresses of sealing, after compressing, described connection pressing plate and fixed lobe have the gap between the two, can be by adjusting the gap between bolt change packing and air inlet-outlet pipe, thereby solve the not good problem of sealing effect that in use causes, easily and effectively because of wearing and tearing.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing at rotary seal position in the utility model.
