Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in figure 1, the novel dryer rotary joint drainage pipeline supporting device comprises a drainage pipe supporting frame 5, a drainage pipe oilless bearing 6 and an oilless bearing sealing cover 7. The drain pipe support frame 5 is fixed inside the middle shaft flange 3 through threads; a bearing placing groove for placing the drain pipe oilless bearing 6 is arranged in the middle of the drain pipe support frame 5, and a drain pipe through hole is formed in the middle of the bearing placing groove; oilless bearing closing cap 7 is fixed through screw thread and bearing standing groove opening side, and drain pipe oilless bearing 6 is placed in the bearing standing groove, locks in the bearing standing groove through oilless bearing closing cap 7.
The drain pipe support frame 5 and the oilless bearing seal cover 7 are made of stainless steel, the drain pipe oilless bearing 6 is made of copper-graphite composite material, and QA19-4+ graphite material is selected in the embodiment.
The bayonet socket that drainage pipe oilless bearing 6 side set up is kept away from to oilless bearing closing cap 7, as shown in fig. 2, evenly is provided with four buckles along the 7 centre of a circle of oilless bearing closing cap in this embodiment, and drainage pipe oilless bearing 6 is close to oilless bearing closing cap 7 side and also is provided with the bayonet socket with the reason, through having the anchor clamps with the anastomotic jack catch of oilless bearing closing cap bayonet socket, can accomplish drainage pipe oilless bearing 6 and oilless bearing closing cap 7's dismouting.
In the drying use process, as shown in fig. 3, the right side of the rotary joint of the dryer is connected with the driven shaft head 2, the right side of the driven shaft head 2 is connected with the middle shaft flange 3, the threaded holes uniformly distributed for a circle are formed in the middle shaft flange 3, and the side wall of the drain pipe support frame 5 is fixed in the middle shaft flange 3 through threads. A drain pipe oilless bearing 6 is arranged in the middle of the drain pipe support frame 5, and the drain pipe oilless bearing is locked by arranging an oilless bearing sealing cover 7; the middle part of the drain pipe oilless bearing 6 runs through a rotary joint L-shaped drain pipe 8, one end of the rotary joint L-shaped drain pipe 8 is supported by a drain pipe support frame 5 and extends to the inner wall of a middle shaft of the dryer, and the other end of the rotary joint L-shaped drain pipe 8 runs through a movable shaft head 2 and a rotary joint to a rotary joint water outlet 11.
When in use, the drier needs to feed steam with 0.6MPa and 160 ℃ to dry wet sludge in the equipment. Steam enters through a steam inlet 1 of the rotary joint and enters a middle shaft 4 through a cavity between the outside of an L-shaped drain pipe 8 of the rotary joint and the inner wall of the driven shaft head, the hot steam in the middle shaft 4 indirectly contacts wet sludge during the operation of the dryer, the moisture in the wet sludge is evaporated, and finally dry sludge with the moisture content of below 40% is obtained. Steam can be rapidly condensed into water to enter a cavity of the middle shaft 4, and with the continuous rotation of the middle shaft 4 (the rotary joint L-shaped drain pipe 8 is relatively static), the steam condensate water in the middle shaft 4 can be discharged through the rotary joint L-shaped drain pipe 8 and the rotary joint water outlet 11 to be sent to a drain tank due to the pressure existing in the middle shaft 4.
When hydrophobic pipe oilless bearing need be changed, demolish the left apron of rotary joint earlier, extend the cavity between rotary joint L type hydrophobic pipe outer wall and rotary joint and the driven spindle nose inner wall with purpose-built bearing extracting tool and extend four bayonet socket positions that the oilless bearing closing cap outside set up (purpose-built bearing extracting tool front end has jack catch and oilless bearing closing cap bayonet socket to cooperate), through rotating the oilless bearing closing cap, thereby can take out oilless bearing closing cap and hydrophobic pipe oilless bearing, accomplished the change to hydrophobic pipe oilless bearing. Compared with the traditional device, the device can finish the replacement of the drain pipe oilless bearing without dismounting the rotary joint and the driven shaft head 2, thereby not only saving manpower and material resources, but also saving a large amount of maintenance time and saving the investment of cost.
