Abstract
The invention provides an arc spacer which is designed and manufactured according to the radian of the arc sealing installation surface of a mill cylinder body and an installation and use method of the arc spacer. By the adoption of the arc spacer and the installation and use method of the arc spacer, the purpose that a rubber sealing gasket can be fully attached to the arc sealing surface is guaranteed, an installation gap is well and tightly pressed and sealed, and the sealing anti-leakage function is achieved. The radian r1 of the arc spacer is equal to the radian r2 of the sealing installation surface of device. The value of the plane size a of a square projection of the arc spacer is 2.5-3 times as large as the diameter D2 of a bolt for sealing and installation. The arc spacer is made of a 3mm-5mm steel plate. The diameter D1 of a center hole is matched with the diameter D2 of the bolt for sealing and installation. The installation method of the arc spacer comprises the steps that an inner lining plate (1) is placed in the arc sealing installation surface, installation holes are aligned, the bolt (2) penetrates through the arc sealing installation surface from inside to outside, the sealing rubber gasket (4) is placed on the portion close to the outer side of the arc sealing installation surface, and the arc spacer (5) is placed outside the sealing rubber gasket (4) and fastened through a nut.
Description
?
Technical field
The present invention relates to a kind of gasket seal of link, be specially the arc pad, be applicable to arc sealing attachment face.
Background technique
The pad generally used at present belongs to flat pad, its attachment face is plane (specifically seeing Fig. 3), for the sealing attachment face of grinding mill barrel, because its sealing attachment face is arc, if after adopting the flat pad installation fastening, sealing rubber pad and grinding mill barrel can not paste entirely fully, can stay assemblage gap, poor sealing performance (specifically seeing Fig. 4), easily cause the seepage of ore pulp, not only causing ore pulp to run off wastes, also affect the health in equipment and operation place, also can process the working efficiency that leakage problems affects equipment because often shutting down, normal production to enterprise impacts.
Summary of the invention
The objective of the invention is for arc equipment attachment face, the deficiency that the mounting plane pad exists, a kind of arc pad and installation and application designed and produced according to the radian of equipment arc attachment face is provided, can guarantee that rubber gasket is fitted on equipment arc attachment face fully, press closely better the installation hole, play better the effect of sealing leakage proof.
The present invention is achieved through the following technical solutions:
A kind of arc pad and installation and application comprise structural design and installation and application two-part of arc pad:
described installation and application is that interior lining panel (1) is placed in arc sealing attachment face (3), and to good mounting hole; With bolt (2), from arc sealing attachment face (3), pass from inside to outside; Place sealing rubber pad (4) in the outside by arc sealing attachment face (3); Place arc pad (5) in the outside of sealing rubber pad (4) again, fastening with nut.
the invention has the beneficial effects as follows
A kind of arc pad of radian making of the sealing of the arc according to grinding mill barrel equipment attachment face is provided, on the cylindrical shell that while installing and using, can make rubber gasket be fitted in grinding machine equipment is is fully faced the wall and meditated, press closely better the installation hole, play better the effect of sealing leakage proof.

Embodiment
As shown in arc pad schematic diagram 1, the structural design of arc pad of the present invention is radian r
1 radian r with the sealing attachment face of grinding mill barrel
2unanimously, when the sealing installation is fastening, could fully rubber gasket be compressed in fact like this, reach to improve sealability is installed, reduce and prevent the effect of seepage.The arc-shaped pad plate plane is projected as square, and its specification a value is installed and used diameter of bolt D for sealing
22.6 times, to ensure enough sealing contact surfaces and intensity.The material of arc pad is the 5mm steel plate, center bore D
1with sealing, the diameter D with bolt is installed
2coupling.
As shown in arc pad scheme of installation 2: a kind of arc pad and installation and application comprise interior lining panel (1), rubber pad (4), the arc pad (5) of sealing attachment face (3), the grinding mill barrel of grinding mill barrel and connect the fixedly bolt of use (2); The interior lining panel (1) of grinding mill barrel installed inside protection grinding mill barrel, fixing bolt (2) is passed from interior lining panel (1) and grinding mill barrel mounting hole, sealing rubber pad (4) is inserted to fixing bolt (2), fixedly between the bolt of use (5), install and be placed into arc pad (5) at rubber pad (4) and connection, intrados and the rubber pad of arc pad (5) are affixed, and the outer arced surface of arc pad (5) (being arcuate surface) is affixed with the nut of bolt (2); The nut of clamping bolt (2), available arc-shaped pad sheet (5) makes rubber pad (4) coordinate with the intimate of grinding mill barrel sealing attachment face (3), plays the effect of sealing leakage proof.
Claims (1)
