Abstract
The utility model relates to the field of a paper-making machine, in particular to a device for sealing a vacuum box in a vacuum roll; the device mainly comprises a sealing groove 3, a sealing strip 4, an elastic device 5 and the like, wherein the sealing strip 4 and the elastic device 5 are arranged in the sealing groove 3; the sealing strip 4 is arranged at the upper part of the elastic device 5; the elastic device 5 is arranged at the bottom of the sealing groove 3; the device is characterized in that a boss is processed on the side wall in the sealing groove 3; a groove is processed at the side of the sealing strip 4 at the part corresponding to the boss arranged on the side wall of the sealing groove 3; and the sealing strip 4 is capable of moving up and down under the action of the elastic device 5, and the sealing strip does not continuously rise until the lower side of the groove of the sealing strip leans against the lower side of the boss of the sealing groove. The device has the beneficial effect that a critical contact state can be realized between the sealing strip 4 and the inner wall of a barrel of the vacuum roll under the condition of guaranteeing the sealing property, so that the losses caused by the abrasion of the sealing strip can be greatly reduced.
Description
Technical field
The utility model relates to the papermaking equipment field, is sealing vacuum box device in a kind of vacuum roll specifically.
Background technique
Vacuum roll is widely used in wet end and the press section of paper machine, is the nucleus equipment of paper machine, and it mainly is comprised of parts such as the vacuum box of cylindrical shell, inner barrel, bearing support assemblies, and some vacuum rolls are also with speed reduction gearing.On paper machine, vacuum roll mainly utilizes the negative-pressure adsorption page in vacuum box or the net blanket is dewatered, in order to guarantee that vacuum box has enough negative pressure, between vacuum box and cylinder inboard wall, good sealing must be arranged, existing seal arrangement mainly contains the parts such as seal groove, Stamping Steel Ribbon, elastic device and forms, and seal groove is the straight trench structure of inwall.Stamping Steel Ribbon and elastic device all are arranged in seal groove, the Stamping Steel Ribbon both sides are straight, coordinate with the inwall of seal groove, Stamping Steel Ribbon generally is wear-resistant macromolecule material or the rubber graphite composite material with good self-lubricating property, elastic device generally is a plurality of spiral compression springs or rubber pneumatic tire, the top that Stamping Steel Ribbon is arranged on elastic device contacts with the roller inwall, the effect of elastic device is to make to be in all the time good contact condition between Stamping Steel Ribbon and cylindrical shell, due to contact all the time between the cylindrical shell of Stamping Steel Ribbon and rotation, elastic force effect lower seal bar at elastic device can produce wearing and tearing, be easily damaged parts, need periodic replacement.In case the Stamping Steel Ribbon excessive wear can not in time be changed, will cause vacuum box degree of vacuum too low, can't reach the usage requirement of production, cause the paper machine to shut down, production is caused damage.The periodic replacement Stamping Steel Ribbon is one of topmost work of vacuum roll, changes Stamping Steel Ribbon and generally vacuum roll could need to be changed from opening roller after the paper machine is pulled down, and have to pay a large amount of expenses for this reason and separately purchase a same vacuum roll as standby.Therefore and the power of consumption is larger simultaneously because Stamping Steel Ribbon has caused Stamping Steel Ribbon " brake " effect to cylinder inboard wall to the pressure of cylinder inboard wall, roller.
Vacuum roll is one of the most expensive roller of paper machine, and the production loss of using the standby roller cause to order, shut down roll change to cause because of Stamping Steel Ribbon, to change the expenses such as Stamping Steel Ribbon, power consumption huge.
The model utility content
In order to extend the working life of vacuum roll sealing vacuum box bar as far as possible, minimizing is because changing the Stamping Steel Ribbon impact that production causes on the paper machine, the utility model provides sealing vacuum box device in a kind of vacuum roll, the Stamping Steel Ribbon of sealing device is when guaranteeing sealing, stop wearing and tearing after making Stamping Steel Ribbon may wear to certain state, and reach a kind of critical contact state between the vacuum roll cylinder inboard wall, thereby the every loss that reduces in a large number or avoid causing because of the Stamping Steel Ribbon wearing and tearing comprises power consumption.
The technological scheme that its technical problem that solves the utility model adopts is: the utility model mainly is comprised of parts such as seal groove, Stamping Steel Ribbon, elastic devices, Stamping Steel Ribbon and elastic device all are arranged in seal groove, Stamping Steel Ribbon is contained in the top of elastic device, the top of Stamping Steel Ribbon contacts with the roller inwall, the inwall of both sides and seal groove coordinates, elastic device is contained in bottom seal groove, and elastic device is rubber pneumatic tire or a plurality of spiral compression spring.It is characterized in that, the sidewall of seal groove is processed with boss, the groove that is processed with at the side of Stamping Steel Ribbon and seal groove corresponding position.
The beneficial effects of the utility model are, the utility model can be when guaranteeing sealing, Stamping Steel Ribbon be may wear to a certain degree stop afterwards wearing and tearing, and reach a kind of critical contact state between the vacuum roll cylinder inboard wall, thereby the every loss that reduces in a large number or avoid causing because of the Stamping Steel Ribbon wearing and tearing comprises power consumption.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation Fig. 1 of the utility model specific embodiment.
Fig. 2 is structural representation Fig. 2 of the utility model specific embodiment.
1. cylindrical shells in figure, 2. vacuum box, 3. seal groove, 4. Stamping Steel Ribbon, 5. rubber pneumatic tire.
Embodiment
The utility model specific embodiment as depicted in figs. 1 and 2, mainly formed by seal groove 3, Stamping Steel Ribbon 4, rubber pneumatic tire 5, Stamping Steel Ribbon 4 and rubber pneumatic tire 5 all are arranged in seal groove 3, Stamping Steel Ribbon 4 is contained in the top of rubber pneumatic tire 5, the top of Stamping Steel Ribbon 4 contacts with the inwall of roller cylindrical shell 1, and rubber pneumatic tire 5 is contained in the bottom of seal groove 3.The inwall of the both sides of seal groove 3 all is processed with boss, and the both sides of Stamping Steel Ribbon 4 are processed with groove.
Fig. 1 is the structural representation of the Stamping Steel Ribbon of the utility model specific embodiment when just having brought into use, the bottom wider portion of Stamping Steel Ribbon 4 also has a segment distance apart from the narrower part of seal groove 3 at this moment, under the effect of rubber pneumatic tire 5, Stamping Steel Ribbon 4 be pressed on cylindrical shell 1 inwall wearing and tearing gradually and gradually on move, until as shown in Figure 2, the bottom of the top seal groove 3 inwall boss in the bottom of Stamping Steel Ribbon 4 lateral grooves, due to stopping of seal groove 3 inwall boss, Stamping Steel Ribbon 4 can not continue mobile, reach the critical contact state between Stamping Steel Ribbon 4 and cylindrical shell 1 inwall, Stamping Steel Ribbon 4 no longer continues wearing and tearing, at this moment, owing to being in the critical contact state between Stamping Steel Ribbon 4 and cylindrical shell 1 inwall, the very little or not friction of friction between Stamping Steel Ribbon 4 and cylindrical shell 1 inwall, because friction between Stamping Steel Ribbon 4 and cylindrical shell 1 inwall produces also decrease of power consumption.
