The beneficial effects of the invention are as follows:
In the filling structure of the existing carbon dioxide fracturing device, the filling of carbon dioxide is most commonly realized by utilizing the matching of the connector on the liquid storage tank and the quick connector of the filling machine, but the filling mode is troublesome in structure matching, and simultaneously needs repeated abrasion of the quick connector, so that leakage phenomenon can not be avoided after a plurality of filling cycles, and other impurities are mixed in the liquid storage tank, therefore, the invention can lead the liquid storage tank to be directly filled through the guiding sealing structure connected on the filling machine without a second connecting structure through the arranged guiding sealing structure, the inner masking cylinder and the gathering ring directly penetrate into the feeding section of the liquid storage tank, firstly, the outermost sealing can be realized through the outer sealing cover, the first-step sealing effect of the outermost end is provided, secondly, the second-step sealing effect of the inner masking cylinder in the middle area is realized through the matching of the inner masking cylinder and the feeding section, and finally, the third-step sealing is realized at the connecting cambered surface of the feeding section and the storage section through the gathering ring which is expanded outwards, so that the sealing is carried out at the bottom, the middle and the top of the feeding section, and the phenomenon of air leakage in the filling stage is avoided.
In the airtight process of the outer sealing cover, firstly, a fixed outer cover for installing the air duct and the telescopic piece is needed, and a rubber seal head for preliminarily sealing the feeding section is arranged at the lower end of the fixed outer cover, so that the rubber ring type fixing is realized, and meanwhile, the carrying platform can be provided.
In order to enable the laminating effect between the gathering ring and the connecting cambered surface to be better, the annular sleeve is arranged on the basis of the gathering ring and can be inflated, the gathering ring is extruded to the outer side at the inner side of the gathering ring, the outer side surface of the gathering ring is tightly attached to the position of the connecting cambered surface, so that the optimal sealing effect is realized at the bottommost position of the feeding section, and the sealing performance is improved to the highest position at the bottommost position.
Because carbon dioxide does not have corrosiveness, the annular sleeve can be provided with an air bag type structure, the air bag structure specifically comprises two parts, namely an annular air bag belt with an outer side for extrusion and a central bag body with an inner side for supporting, the central bag body is used for connecting a straight flushing pipe, the annular air bag belt can be driven by the central bag body to push up in the process of moving up the straight flushing pipe, a stronger lateral pressure is formed on a connecting cambered surface, and in order to prevent the whole air bag structure from deforming when the central bag body is pulled by the straight flushing pipe, supporting ribs are arranged in the central bag body, so that the local compressed position deformation is avoided.
When the structure of the air bag is fixed, a certain sliding deviation phenomenon exists, so that the sealing performance is easily influenced, therefore, the invention adopts a mode of arranging the magnet at the outer side of the gathering ring, so that the gathering ring can be adsorbed on the connecting cambered surface of the liquid storage tank through the magnet, when the structure is pulled by the secondary sealing and pressing structure, the magnet can move upwards because the adsorption capacity of the magnet is not so strong, the magnet and the magnet are not interfered, and when the whole air bag structure is completely contracted inwards by negative pressure, the magnet separated from the inner wall of the liquid storage tank can also be used as a counterweight to gather the whole gathering ring to the middle, thereby being more convenient for a user to take out the smooth sealing structure and the secondary sealing and pressing structure from the liquid storage tank.
The gathering ring is in an outward-expanding horn-shaped structure because the gathering ring needs to be matched with the connecting cambered surface, but the gathering ring is inconvenient to extend into and out of the feeding section, and the secondary sealing structure is further arranged on the basis of the forward sealing structure, the straight flushing pipe in the secondary sealing structure can be communicated with the gathering ring to realize the positive pressure expansion and the negative pressure contraction of the gathering ring, the annular sleeve is sucked when the feeding section needs to extend into or out of the gathering ring, the gathering ring connected with the annular sleeve is contracted in the gathering ring, the gathering ring is contracted into the same diameter as the inner mask cylinder or smaller than the inner mask cylinder, and the gathering ring is conveniently taken out.
Although the annular sleeve can exert a certain extrapolation effect on the gathering ring, compared with carbon dioxide with very large filling body quantity, the sealing effect is always inferior, so the invention is provided with the telescopic piece on the basis of gathering the ring, the annular sleeve and the straight flushing pipe, the telescopic piece is connected with the whole annular sleeve through the straight flushing pipe, and the annular sleeve is abutted on the gathering ring, so the gathering ring is further extruded on the connecting cambered surface when the telescopic piece pulls the straight flushing pipe, and the clearance between the gathering ring and the connecting cambered surface is smaller, thereby realizing complete sealing.
