Abstract
The utility model provides a sealing device for a vacuum box body. The device is high in sealing performance and convenient to replace, the problem that the conventional sealing device is required to be wholly replaced when abraded is solved, and cost is saved. The device comprises a U-shaped steel sleeve which is fixed at the upper end of the vacuum box body. Two sealing strips are clamped in a U-shaped groove of the steel sleeve, and are buckled into an L shape.
Description
Technical field
The utility model relates to a kind of paper making equipment, in particular for the sealing device of suction press roll, is specially a kind of sealing device of vacuum chamber.
Background technology
The quality of sealing, be directly connected to work quality and the service life of a machinery equipment, the function one of sealing is to prevent that the liquid of machine intimate or gas from leaking out from the faying face of two parts, the 2nd, prevent outside impurity, dust intrusion, keep the necessary environment of machine components normal operation; Existing hermetically-sealed construction at the vacuum chamber that is used for suction press roll of paper machine, adopt whole sealing strip, it is as a whole, as shown in Figure 1 and Figure 2, but in the course of the work, have friction between the sealing strip 3 of this structure and the steel bushing 1, sealing strip also is worn easily, and then has influence on sealing, so just must carry out integral replacement, but the part of displacement often only needs the part of sealing wear, if integral replacement just causes waste, has improved production cost.
Summary of the invention
For the problems referred to above, the utility model provides a kind of sealing device of vacuum chamber, and this installs favorable sealing property, and changes conveniently, has solved the defective that existing sealing wear needs integral replacing, provides cost savings.
Its technical scheme is such: it comprises steel bushing, described steel bushing is fixed in the vacuum chamber upper end, and described steel bushing is U-shaped, and card has sealing strip in the U-shaped groove of described steel bushing, it is characterized in that: described sealing strip is provided with two, and two described sealing strips are L-type and mutually fasten.
The beneficial effects of the utility model are, card has two to be the sealing strip that L-type fastens mutually in steel bushing, the structure that has replaced an integral sealing bar of existing employing, like this in the time of work, steel bushing and sealing strip wear and tear, and also only need to partly change main friction portion or serious wear, need not integral replacement, avoided unnecessary waste, provided cost savings.
Description of drawings
Fig. 1 is the structural representation of existing sealing device;
Fig. 2 is the structural representation of existing sealing strip;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is the structural representation of the utility model sealing strip.
The specific embodiment
As shown in Figure 3, Figure 4, the utility model comprises steel bushing 1, steel bushing 1 is fixed in vacuum chamber 2 upper ends, steel bushing 1 is U-shaped, the U-shaped groove 4 interior cards of steel bushing 1 have sealing strip 3, sealing strip 3 is provided with two, two sealing strips 3 are L-type and mutually fasten, the structure that has replaced an integral sealing bar of existing employing, in the time of work, steel bushing 1 weares and teares with sealing strip 3 like this, also only need to partly change main friction portion or serious wear, need not integral replacement, avoided unnecessary waste, provide cost savings.
