Abstract
The invention discloses a hole sealing bag with a magnetic stirring function, which comprises a bag body. The middle of the bag body is provided with a separating device capable of being opened and closed, the separating device divides the bag body into two portions which are separated from each other, two components of a foam material are correspondingly filled in the two portions, and a magnetic stirring part is installed in the bag body. The hole sealing bag with the magnetic stirring function utilizes the characteristic that the magnetic stirring part can rotate at a high speed and stir mixed liquid under the effect of a magnetic stirrer, enables the two components of the foam material to be evenly mixed in a very short time and fully react later on, and remarkably improves hole sealing effects.
Description
Technical field
The present invention relates to a kind of mine gas extraction hole plugging device, relate in particular to a kind of sealing of hole bag with magnetic agitation function.
Background technology
The method of comparatively widely used dual-component polyurethane shutoff gas extraction hole is at present: is two kinds of components of dual-component polyurethane that isocyanates and combined polyether are sprinkling upon on weaving or the braiding material in proportion; Stir a little, be bundled in and send gas extraction hole on the releasing pipe to; Or earlier above-mentioned fabrics is bundled on the releasing pipe, again two kinds of components of polyurethane are watered to be put on and send on the fabric in the extraction hole.Although this kind method goes a step further before using shutoff such as cement and cement admixture,, defectives such as this kind method for blocking exists that proportioning is inaccurate, undercompounding, material is wasted and plugging effect is relatively poor.
The patent No. is that 200620118135.9 patent of invention discloses the on-the-spot polyurethane foam bag of a kind of hand; The patent No. is that 201010220304.0 patent of invention discloses a kind of method of using polyurethane foam bag shutoff gas extraction hole, and the patent No. is that 201020608399.9 patent of invention discloses a kind of pocket type hole sealing device; The common ground of above-mentioned patent is all to use sealing of hole bag shutoff gas extraction hole; Its sealing of hole bag is made up of the separating device at bag and bag middle part; Separating device is divided into bag corresponding one by one two kinds of components that fill expanded material in two parts and two parts of mutual isolation, earlier the sealing of hole bag is fixed on the releasing pipe during use, then separating device is opened (extruding is washed in the isolation envelope open or taken off seal bar); Make that two kinds of components of expanded material are flowed to together in the sealing of hole bag; Rub sealing of hole bag 10-20 with hand rubbing subsequently and second two kinds of components are mixed each other, together send in the extraction boring with being about to sealing of hole bag and releasing pipe, expanded material begins foaming afterwards; And finally burst the sealing of hole bag, realize the sealing of hole operation.
But there is following problem in existing sealing of hole bag technique:
1. rub the mixed effect extreme difference by hand, can't realize even mixing at short notice; Generally speaking; After two kinds of components of expanded material mix in the sealing of hole bag; In 3-4 minute, just can foam and then burst the sealing of hole bag, therefore (10-20 second) accomplished married operation in a short period of time, rubs in the so short time by craft and can't accomplish even mixing;
2. two of expanded material kinds of components can't evenly mix then and can't realize abundant reaction; This will cause waste of material on the one hand; Can have a strong impact on the key elements directly related with the down-hole sealing of hole such as intensity, toughness, rate of closed hole of reaction back material on the other hand, the sealing of hole effect is had a strong impact on.
Summary of the invention
In view of this, the invention provides a kind of sealing of hole bag, two kinds of components of expanded material are evenly mixed and fully reaction, significantly improve the sealing of hole effect with magnetic agitation function.
Sealing of hole bag with magnetic agitation function of the present invention; Comprise bag; Said bag middle part is provided with separating device to be opened/closed; Said separating device is divided into bag corresponding one by one two kinds of components that fill expanded material in two parts and two parts of mutual isolation, and magnetic agitation is housed in the said bag.
Further, said separating device is the clips that is held on the bag external surface;
Further, said separating device is self hot pressing isolation strip at bag middle part;
Further, said separating device is the concavo-convex lock that is arranged at the bag inner surface;
Further, said expanded material is a polyurethane foam material.
Beneficial effect of the present invention is: magnetic agitation has been installed in the present invention additional in the sealing of hole bag, when using the present invention to carry out the sealing of hole operation, earlier the sealing of hole bag is fixed on the releasing pipe; Then separating device is opened, made that two kinds of components of expanded material are flowed to together in the sealing of hole bag, subsequently the sealing of hole bag is placed on the magnetic stirring apparatus; The external magnetic field that utilizes the magnetic stirring apparatus polarization constantly to change promotes the rotation at a high speed in the sealing of hole bag of magnetic agitation; Thereby two kinds of components of expanded material are evenly mixed, together send in the extraction boring with being about to sealing of hole bag and releasing pipe, expanded material begins foaming afterwards; And finally burst the sealing of hole bag, realize the sealing of hole operation; The present invention utilizes magnetic agitation under the magnetic stirring apparatus effect, to rotate the characteristic that mixes liquid at a high speed, and two kinds of components of expanded material are mixed in a short period of time, and fully reaction subsequently, has significantly improved the sealing of hole effect.
Description of drawings
In order to make the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that the present invention is made further detailed description below, wherein:
Fig. 1 is the structural representation of the embodiment of the invention 1;
Fig. 2 is the structural representation of the embodiment of the invention 2;
Fig. 3 is the structural representation of the embodiment of the invention 3;
Fig. 4 is the A-A sectional view of Fig. 3.
The specific embodiment
Below will carry out detailed description to the preferred embodiments of the present invention with reference to accompanying drawing.
Fig. 1 is the structural representation of the embodiment of the invention 1; As shown in the figure; The sealing of hole bag with magnetic agitation function of present embodiment comprises bag 1, and said bag 1 middle part is provided with separating device to be opened/closed; Said separating device is divided into bag 1 corresponding one by one two kinds of components that fill expanded material in two parts (being divided into left and right sides two parts 1a and 1b among the figure) and two parts of mutual isolation, and magnetic agitation 2 is housed in the said bag 1.
In the present embodiment, said separating device is the clips 3 that is held on bag 1 external surface.
