Detailed Description
Referring to fig. 1 and 2, a cable conveying hydraulic drive continuous ash pouring barrel is composed of a hydraulic drive device 1 and an ash pouring barrel 2; the hydraulic driving device 1 comprises an upper joint 11, a filter screen 12, an electromagnetic valve 13, a sliding sleeve 14 and a cylinder 15; the upper joint is in threaded connection with the cylinder 15, the filter screen 12 is arranged in the cylinder 15, the lower end of the filter screen 12 is connected with the upper end of the electromagnetic valve 13 through threads, and the sliding sleeve 14 is sleeved at the lower end of the device; the ash pouring barrel 2 comprises an upper connector 21, an ash barrel 22, a plug 23, a sheath 24 and a shear pin 25, wherein the upper connector 21 is connected with the sliding sleeve 14, the lower end of the upper connector is welded with the ash barrel 22, the lower end of the ash barrel 22 is in threaded connection with the sheath 24, the plug 23 is arranged in the sheath 24, and the shear pin 25 is arranged in a side threaded hole at the lower end of the sheath 24; the upper end of the upper joint 11 is provided with external threads connected with a screw tap.
After the cement mortar is conveyed to the designed ash pouring well depth through a cable, a control cable circuit is manually operated on the ground, so that a valve of the electromagnetic valve device is opened, well fluid is directly pressurized on cement mortar after entering the lower end of the electromagnetic valve from the filter screen, after the cement mortar is pressurized, the plug is directly pushed to move downwards and shear pins are cut off, the valve plug continues to move downwards to open a cement mortar outlet, and the cement mortar flows into the sleeve along the outlet. The continuous ash pouring operation is realized by repeated operation. The specific operation is as follows: before being applied to the cable conveying and ash pouring, the sliding sleeve is connected to a connecting head on an ash pouring barrel; connecting the lower end of the cable faucet to the upper connector; the ash pouring barrel device is put into the sleeve and hung in the sleeve by the fork plate; pouring cement mortar into the ash pouring barrel device, filling the cement mortar, and then lowering the cement mortar through a cable to suspend the electromagnetic valve device in the sleeve; the lower discharging cable puts the ash pouring device into the designed ash pouring well deep position. After the electric appliance panel switch is operated on the ground, the underground electromagnetic valve device is opened, the casing ring blank well liquid enters the upper end of cement mortar for pressurization, the cement mortar opens the valve plug, and the cement mortar flows into the casing.
