Abstract

The utility model relates to a processing treatment slot squeeze roll sealing device comprising a sealing door, and is characterized in that the upper of the sealing door which is positioned on the inner side of a slot body has a lap suspending on the inner side of the slot body, and the middle of the sealing door which comprises a left half door and a right half door is provided with an upper and a lower round holes which are cooperated with the squeeze roll shaft. The sealing door is welded by two parallel doors into an integraty, and the two sealing doors are fixed by steady dowels. A hanging panel which is provided between the inner side of the slot body and the sealing door is fixedly hanged on the slot body, wherein the upper of the hanging panel is fixed with a h-shaped gain groove which is applicable to the slot edge, and the upper side of the h-shaped gain groove on hanging panel bears the sealing door as a supporting slideway. The utility model has the advantages of simple structure, convenient repairing, and low cost, thereby overcoming the shortcomings of the conventional squeezing roll sealing device.

Description

PROCESS FOR TREATMENT groove squeeze roll sealing device

(1) technical field

The utility model relates to PROCESS FOR TREATMENT groove squeeze roll sealing device.

(2) background technology

PROCESS FOR TREATMENT grooves such as the descaling bath of domestic present cold rolling mill, alkaline bath, rinse bath all are furnished with squeeze roll, squeeze roll has transmission, what have does not then have a transmission, no matter have or not transmission, the face that a needs sealing is all arranged between the axle of squeeze roll and the cell body is to guarantee the not excessive influence of the gas environment on every side in the groove.This is to energy savings, and the protection environment all plays a very important role.The principle of the sealing device that uses all is to keep little negative pressure in the groove at present, adopts the double-layer seal form that is similar to labyrinth seal at roll shaft neck place.Existing seal form is the both sides inside and outside cell body respectively that doubling plate has, the medial side that then is mounted in cell body that has, and a common problem of these two kinds design existence is exactly the structure more complicated.The form that is installed in the cell body medial side needs the slideway of complex forms because structural requirement, and slideway is by corrosion-resistant wear-resisting again acid-proof ceramics manufacturing, at present domesticly also can't make, and needs import.It is not only complicated, and expense costliness, also have following point in particularly using: 1, inside and outside two-layer slide plate need be in good parastate when sliding, but non-metal board distortion in use for some time makes that very difficult assurance is parallel, causes the difficulty of sliding; 2, because slideway is in the cell body middle part, particularly in the medial side slideway solution crystallization is arranged, more feasible slip difficulty, each maintenance need take much time and open hermatic door, and the time has been grown, cell body position well damage.

(3) summary of the invention

The purpose of this utility model is to provide a kind of PROCESS FOR TREATMENT groove squeeze roll sealing device, and this squeeze roll sealing device structure is simple, easy to maintenance, and cost is low, has overcome existing sealing device defective.

The utility model is achieved in that a kind of PROCESS FOR TREATMENT groove squeeze roll sealing device, comprise hermatic door, it is characterized in that: hermatic door is positioned at the cell body inboard, hermatic door top is equipped with lug and is suspended on the cell body inboard, hermatic door is made up of left and right sides single door, hermatic door middle part have up and down two with extract the circular hole that roll shaft matches.

Described hermatic door is welded into an integral body by the parallel door of two fans, is fixed by shop bolt between two hermatic doors.

Describedly between cell body inboard and hermatic door, link plate is housed, the link plate upper end be fixed with groove along the h type groove that adapts, link plate fixedly is articulated on the cell body, the h type groove upside on the link plate bears hermatic door as supporting skid rail.

Described link plate is the polypropylene board of lining steel plate, and gathering in the link plate back, rivet clasp is followed closely and the cell body inboard links into an integrated entity.

The utility model is to adopt the formation labyrinth sealing that matches of annulus on acid tank body inboard is provided with the two seals door and is installed in roll shaft, and adding has little negative pressure and form sealing in the groove; Hermatic door is suspended on the link plate of cell body inboard and can slides along the cell body wall, maintains easily and overhauls.

The utility model is simple in structure, and is easy to maintenance, and cost is low, thereby overcome existing squeeze roll sealing device defective.

Among the figure: 1 water seal, 2 hermatic doors, 3 link plates, 4 cell bodies, 5 slopes, 6 feeders, 7 extract roll shaft, 8 left single doors, 9 right single doors, 10 rivet clasps nail, 11 pins, 12 lugs.

(5) specific embodiment

Referring to Fig. 1, a kind of PROCESS FOR TREATMENT groove squeeze roll sealing device comprises hermatic door 2, and hermatic door 2 is positioned at cell body 4 inboards, and hermatic door 2 tops are equipped with lug 12 and are suspended on cell body 4 inboards.Referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5, hermatic door 2 is made up of left and right sides single door 8,9, hermatic door 2 middle parts have up and down two with extract the circular hole that roll shaft 7 matches, hermatic door 2 is welded into an integral body by the parallel door of two fans, is fixed by shop bolt 11 between two hermatic doors.

Referring to Fig. 1, Fig. 6, Fig. 7; slip for ease of hermatic door 2; between cell body 4 inboards and hermatic door 2, link plate 3 is housed; link plate 3 is the polypropylene board of lining steel plate; the densely covered rivet clasp nail 10 in link plate 3 backs links into an integrated entity with cell body 4 inboards, and polypropylene link plate 3 has replaced original acid-proof ceramic tile to form cell body 4 internal protection layers.Link plate 3 upper ends are fixed with the h type groove that adapts with cell body 4 upper edges, and the h type groove upside of link plate 3 upper ends bears hermatic door 2 as supporting skid rail, about the lug 12 partly fanned on the hermatic door 8,9 can slide along the h type groove upside on the link plate 3.

The labyrinth seal that hermatic door 2 by being suspended on cell body 4 inboards forms and be installed in the annulus of extracting on the roll shaft 7 and match adds little negative pressure that groove is interior and forms sealing.

Water seal 1 is housed above hermatic door 2, downside cell body 4 designs of hermatic door 2 have slope 5, can guarantee that like this acid solution that cools down is back to smoothly in the acid tank and does not assemble on hermatic door 2, the outside at acid tank, the feeder 6 that links to each other with cell body 4 is arranged, prevent that the acid solution when abnormal conditions take place from overflowing.

The utility model is simple in structure, and is easy to maintenance, and cost is low, overcome the defective of existing squeeze roll sealing device.
