Description
Technical field:
The utility model belongs to mechanical engineering technical field, relates to the roller-way of carrying usefulness in the metallurgical equipment in the hot operation zone, particularly a kind of interior cold roller-way water-tight device.
Background technology:
At present, in smelter,, generally carry the roller-way of usefulness to adopt the roller-way of the inner type of cooling of a kind of roller in the hot operation zone according to the working condition requirement difference of reality.This roller-way adopts the double-lipped sealing that roller-way bearing and water outlet are cut off by roller one end water-in and water-out.But often because the metallurgical plant operating mode is more abominable, many, the interior cold roller water outlet cooling water expansion tank water yields of dust are bigger, and the long-term and double-lipped sealing contact of cooling water expansion tank frequently causes phenomenons such as bearing water inlet, roller jam.Conventional way is to shut down maintenance, changes bearing or sealing, and then installs.Not only strengthen the consumption of standby redundancy, also have a strong impact on production time, cause productive costs and maintenance workload to heighten.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of interior cold roller-way water-tight device is provided.Cold roller roller-way bearing waterproof has not only solved the long-term problem that causes bearing to be intake easily that contacts with cooling water expansion tank of double-lipped sealing with the cooling water expansion tank drainage pattern in of the present utility model, and both made in double-lipped and seal when badly damaged, can guarantee that also cooling water expansion tank do not invade bearing inside in the short time.Reduce productive costs and maintenance workload, enhance productivity.
For achieving the above object, the technical scheme that the utility model adopted is:
Cold roller-way water-tight device in a kind of comprises roller-way, roller bed frame, bearing seat and cooling water inlet pipe, and roller-way two ends roll shaft is arranged in the bearing seat by bearing respectively, and bearing seat is arranged on the roller bed frame; Cooling water inlet pipe one end passes roll shaft and stretches into the roller-way inner chamber, and passes from cooling water outlet pipe water exit center, and housing is fixed in the outer end; Cooling water outlet pipe and roller-way weld together is characterized in that: the partition panel outer ring is welded on the drain chamber inwall, and drain chamber is divided into internal drainage chamber and outer drain chamber; Cooling water outlet pipe passes partition panel and puts in outer drain chamber; Be provided with a discharge port outside in the drain chamber and connect outer drain hose, in the internal drainage chamber, be provided with a discharge port simultaneously and connect internal drainage pipe.
Between double-lipped sealing and inner chamber, the seal stack device also is set at least, can store up a small amount of grease, prevent that further cooling water expansion tank from entering the roller-way bearing.
When described cooling water outlet pipe passes partition panel, leave the gap that cooling water outlet pipe can be rotated with roller-way between the two.
Actual effect of the present utility model is: after dividing the draining of inside and outside chamber, actv. has cut off double-lipped sealing and the chance that a large amount of cooling water expansion tanks contact, and greatly reduces the probability that causes the bearing water inlet because of sealing wear; Even the lip packing severe wear because the inner chamber water yield seldom, and have the shutoff of labyrinth packing (containing a small amount of grease), also is difficult to water inlet, thereby effectively protects bearing in the roller-way bearing short time.
Description of drawings:
Fig. 1 is the running condition scheme drawing of the utility model one embodiment;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is an A of the present utility model portion enlarged drawing;
Fig. 4 is a B of the present utility model portion enlarged drawing.
Among the figure, part 1 is that roller-way, part 2 are that cooling water inlet pipe, part 3 are that cooling water outlet pipe, part 4 are that bearing, part 5 are that double-lipped seal ring, part 6 are that labyrinth packing, part 7 are that drain chamber shell, part 8 are that outer drain chamber, part 9 are that internal drainage chamber, part 10 are that internal drainage pipe, part 11 are that partition panel, part 12 are that outer drain hose, part 13 are that bearing seat, part 14 are roller bed frame.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing 1～4:
Roller-way 1 two ends roll shaft is arranged in the bearing seat 13 by bearing 4 respectively, and bearing seat 13 is arranged on the roller bed frame 14; Cooling water inlet pipe 2 is fixed on the drain chamber shell 7 by bolted connection, and passes from cooling water outlet pipe 3 water exit centers and to stretch into roller-way 1 inside; , drain chamber shell 7 is fixing with bearing seat 13; Cooling water outlet pipe 3 and roller-way 1 weld together; Partition panel 11 outer rings are welded on the drain chamber inwall, and drain chamber is divided into internal drainage chamber 9 and outer drain chamber 8; Cooling water outlet pipe 3 passes partition panel 11, puts in outer drain chamber 8; Be provided with a discharge port outside in the drain chamber 8 and connect outer drain hose 12, in internal drainage chamber 9, be provided with a discharge port simultaneously and connect internal drainage pipe 10.
