Abstract
The invention discloses a spindle sealing device in a centrifugal machine. The spindle sealing device comprises a bearing block and a drum. A spindle is movably arranged in the bearing block via a pair of bearings, bearing block end covers which sleeve the spindle are respectively arranged at the upper end and the lower end of the bearing block, a space between each bearing block end cover and the spindle is sealed by a sealing ring, the upper end of the spindle extends out of the bearing block end cover at the upper end of the bearing block and then is fixed to the drum, and a sealing sleeve sleeves the portion, which is positioned between the drum and the bearing block end cover at the upper end of the bearing block, of the spindle and completely covers the portion, which is positioned between the drum and the bearing block end cover at the upper end of the bearing block, of the spindle. The spindle sealing device has the advantages that corrosion damage to the spindle due to corrosive gas in a centrifugal machine case can be prevented, and accordingly the service life of the spindle can be prolonged.
Description
Technical field
The present invention relates to centrifuge, be specifically related to the main shaft sealing device in centrifuge.
Background technology
The structure of centrifuge comprises: inside is provided with the centrifugal cabinet of rotary drum, bottom in centrifugal cabinet is provided with bearing block, main shaft is movably arranged in bearing block by pair of bearings, at the upper and lower two ends of bearing block, be respectively arranged with top chock end cap and the step end cap being sleeved on main shaft, between top chock end cap and main shaft and seal mutually by sealing ring respectively between step end cap and main shaft, the upper end of main shaft fixes with rotary drum after stretching out top chock end cap.The shortcoming of this centrifuge is: in centrifugal cabinet, mostly be acid or alkaline corrosive gas, because the main shaft between top chock end cap and rotary drum is naked state, these corrosive gas easily carry out corrosive wear to part exposed on main shaft, between main shaft after corrosion and sealing ring, easily produce gap, these corrosive gas can enter bearing block internal corrosion bearing by this gap, not only make Main Shaft Service Life short, and buried hidden danger for production safety.
Summary of the invention
The object of this invention is to provide a kind of main shaft sealing device that can prevent that main shaft is corroded in the centrifuge damaging.
For achieving the above object, the present invention has adopted following technical scheme: the main shaft sealing device in described centrifuge, comprise bearing block and rotary drum, main shaft is movably arranged in bearing block by pair of bearings, two ends up and down at bearing block are respectively arranged with the bearing cover being sleeved on main shaft, between each bearing cover and main shaft, by sealing ring, seal mutually respectively, after the bearing cover of the projecting shaft bearing upper end, upper end of main shaft, fix with rotary drum, on the bearing cover of bearing block upper end and the main shaft between rotary drum, be set with sealing shroud, sealing shroud envelopes the bearing cover of bearing block upper end and the main shaft between rotary drum completely.
Further, the main shaft sealing device in aforesaid centrifuge, wherein: upper end and the rotary drum of sealing shroud fixes, bearing cover is inserted in lower end, seals by sealing ring between sealing shroud lower end and bearing cover mutually.
By the enforcement of technique scheme, the present invention has advantages of and can avoid main shaft to be centrifuged corrosive gas corrosion and damage in cabinet, can to extend Main Shaft Service Life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the main shaft sealing device in centrifuge of the present invention.
Fig. 2 is the enlarged diagram at the H position shown in Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, shown in Fig. 2, main shaft sealing device in described centrifuge, comprise bearing block 1 and rotary drum 2, main shaft 3 is movably arranged in bearing block 1 by pair of bearings 4, at the two ends up and down of bearing block 1, be respectively arranged with the top chock end cap 5 and step end cap 6 that are sleeved on main shaft, between top chock end cap 5 and main shaft 3, and by sealing ring, seal mutually respectively between step end cap 6 and main shaft 3, top chock end cap 5 is stretched out afterwards in the upper end of main shaft 3 and rotary drum 2 fixes, on the main shaft 3 between top chock end cap 5 and rotary drum 2, be set with sealing shroud 7, sealing shroud 7 envelopes the main shaft 3 between top chock end cap 5 and rotary drum 2 completely, in the present embodiment, the upper end of sealing shroud 7 by bolt and rotary drum 2 fix, lower end inserts top chock end cap 5, between sealing shroud 7 lower ends and top chock end cap 5, by sealing shroud sealing ring 8, seal mutually, make to be like this connected between sealing shroud 7 and rotary drum 2 and sealing shroud 7 and top chock end cap 5 more firm, guaranteed the sealing of the main shaft 3 between 7 pairs of top chock end caps 5 of sealing shroud and rotary drum 2, avoid the corrosion of centrifugal cabinet internal corrosion gas to main shaft, and then extended the service life of main shaft.
Claims (2)
1. the main shaft sealing device in centrifuge, comprise bearing block and rotary drum, main shaft is movably arranged in bearing block by pair of bearings, two ends up and down at bearing block are respectively arranged with the bearing cover being sleeved on main shaft, between each bearing cover and main shaft, by sealing ring, seal mutually respectively, after the bearing cover of the projecting shaft bearing upper end, upper end of main shaft, fix with rotary drum, it is characterized in that: on the bearing cover of bearing block upper end and the main shaft between rotary drum, be set with sealing shroud, sealing shroud envelopes the bearing cover of bearing block upper end and the main shaft between rotary drum completely.
