Abstract
A double feed sealing and anti-entering of liquid into a bearing bush device of a ball grinding mill comprises a feed pipe, an adjustable sealing gland, a bolt fastener, a guide ring, a feed sleeve, a seal packing, a VD-shaped seal ring, and an end cover. The feed sleeve is connected with the feed pipe in sleeved mode. The seal packing is arranged between the feed sleeve and the feed pipe. The guide ring and the adjustable sealing gland are arranged on the outer side of the seal packing, wherein the guide ring is tightly pressed against the outer side of the seal packing. The guide ring and the adjustable sealing gland are installed on the feed sleeve through the bolt fastener. The VD-shaped seal ring is installed on the feed pipe at the inner side of the feed sleeve. The feed sleeve and the end cover are connected through a flange. The flange is higher than the end cover at the joint. The double feed sealing and anti-entering of liquid into the bearing bush device of the ball grinding mill has the advantages that a double feed sealing structure, the guide ring and a isolation strip structure are combined as a whole to effectively avoid liquid leakage and guide the leaked liquid to timely flow out; the isolation strip is additionally arranged to effectively prevent the leaked liquid from entering into the bearing bush oil tank of a main bearing, substantially reducing 'bush burning' phenomenon of the main bearing.
Description
Technical field
The utility model belongs to mechanical engineering field, relates to the sealing of a kind of feeding of ball mill and prevents that slurries from entering the bearing shell device, the dual feeding seal of especially a kind of ball mill and prevent that slurries from entering the bearing shell device.
Background technology
At present, feeding of ball mill sealing is generally the asbestos packing sealing, because long-time running, slurries easily ooze out from the feed end sealing, and the slurries that ooze out are along with the running of grinding machine easily enters main brasses, thereby causes the base bearing tile kilning.
The utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, the textural association of a kind of dual feeding seal structure+guide ring+isolation strip is provided, i.e. the dual feeding seal of ball mill and prevent that slurries from entering the bearing shell device.
For achieving the above object, the utility model adopts following technical proposals:
The dual feeding seal of a kind of ball mill and prevent that slurries from entering the bearing shell device comprises feed pipe, adjustable sealing gland, and bolt fastener, guide ring, bushing for feeding, sealed packing, the VD sealing ring, end cap, described bushing for feeding is enclosed within on the feed pipe; Be provided with sealed packing between described bushing for feeding and the feed pipe; The sealed packing outside is provided with guide ring and the adjustable sealing gland that presses on it; Described guide ring and adjustable sealing gland are installed on the bushing for feeding by bolt fastener; Described VD sealing ring is contained on the feed pipe of bushing for feeding inboard; Described bushing for feeding is connected by flange with end cap, and the junction flange exceeds end cap.Described adjustable sealing gland is split-type structural.Described guide ring is split-type structural.Described bushing for feeding and end cap junction flange exceed end cap 20-30mm.
Cylindrical shell is in rotation process, feed pipe is relative with the VD sealing ring static, guide ring, adjustable sealing gland and sealed packing rotate with cylindrical shell, along with barrel body rotation, slurries in the end cap can impact on the VD sealing ring, the VD sealing ring plays the effect that stops, if slurries flow out by the slit between VD sealing ring and the bushing for feeding, also has the sealed packing sealing.If slurries flow out by the wearing clearance of sealed packing and feed pipe, can also the slurries water conservancy diversion be gone out by guide ring, the slurries of Leakage prevention accumulate near the sealed packing, affect sealing effectiveness.When truly having the slurries of leakage, the slurries of the effective Leakage prevention in isolation strip that forms between bushing for feeding and the end cap enter in the main brasses oil sump, thereby have guaranteed that bearing faying face cleaning is difficult for " tile kilning ".
The beneficial effects of the utility model are, dual feeding seal structure+guide ring+isolation strip textural association, not only effectively avoided the leakage of slurries, but also the timely water conservancy diversion of the slurries that leak out can be gone out, the isolation strip of setting up, the slurries of effectively having avoided leaking enter in the main brasses oil sump, greatly reduced the generation of base bearing " tile kilning " phenomenon, simple in structure, cost is low, and result of use is obvious.
Description of drawings
Fig. 1 is structural plan of the present utility model;
Fig. 2 is the partial enlarged drawing at I place on the utility model Fig. 1
Wherein: 1. feed pipe, 2. adjustable sealing gland, 3. bolt fastener, 4. guide ring, 5. bushing for feeding, 6. sealed packing, 7.VD sealing ring, 8. end cap, 9. main brasses, 10. isolation strip.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, 2, guide ring 4 is together pushed down sealed packing 6 by bolt fastener 3 and adjustable sealing gland 2, and described guide ring 4, adjustable sealing gland 2 are split type, is easy to install.Bushing for feeding 5 one sides are installed sealed packing 6, and opposite side is that feed pipe 1 is installed, and VD sealing ring 7 is installed on the feed pipe 1.Bushing for feeding 5 exceeds end cap 20-30mm with the flange of end cap 8 junctions, forms the isolation strip.Adjustable sealing gland 2 is adjusted according to the abrasion condition of sealed packing 6, guarantees that effectively sealed packing 6 is in impaction state, is contained in the VD sealing ring 7 on the feed pipe 1, consists of double sealing structure with above-mentioned sealed packing 6.Guide ring 4 links together with adjustable gland 2, timely the slurries water conservancy diversion that leaks out is gone out.Form the isolation strip between bushing for feeding 5 and the end cap 8, effectively the slurries of Leakage prevention enter in the oil sump of main brasses 9.
Cylindrical shell is in rotation process, feed pipe 1 is relative static with VD sealing ring 7, guide ring 4, adjustable sealing gland 2 and sealed packing 6 rotate with cylindrical shell, along with barrel body rotation, slurries in the end cap 8 can impact on the VD sealing ring 7, VD sealing ring 7 plays the effect that stops, if slurries flow out by the slit between VD sealing ring 7 and the bushing for feeding 5, also has sealed packing 6 sealings.If slurries flow out by the wearing clearance of sealed packing 6 with feed pipe 1, can also the slurries water conservancy diversion be gone out by guide ring 4, the slurries of Leakage prevention accumulate near the sealed packing 6, affect sealing effectiveness.When truly having the slurries of leakage, the slurries of the effective Leakage prevention in isolation strip that forms between bushing for feeding 5 and the end cap 8 enter in main brasses 9 oil sumps, thereby have guaranteed that bearing faying face cleaning is difficult for " tile kilning ".
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
