Problems solved by technology

In severe cases, the conveying system of the ash tank cannot blow away the agglomerated cement or bentonite, so that the agglomerated material is blocked in the pipeline, so that the material in the ash tank cannot be transported to the mixing site
Once this situation occurs, the platform operator must open the manhole of the ash tank and disassemble the pipeline of the conveying system for manual cleaning, resulting in a lot of unnecessary manual labor

Embodiment Construction

[0011] attached by figure 1 It can be seen that the present invention includes the ash-dispersing tank 2 and the emptying main pipe 1 and the intake main pipe 4 connected thereto, and also includes the ash-inlet main pipe 3 and the ash-out main pipe 5 connected with the ash-dispersing tank 2, and the described emptying main pipe 1 A bypass exhaust valve 002 is provided on the pipeline connected with the ash scattered tank 2, and a bypass air intake valve 001 is provided on the pipeline connected with the ash scattered tank 2 of the air intake main pipe 4. See attached figure 2 , the purging steps are as follows: a. Open the system controller, start the preset metering and control operation, and when the preset time is reached, the bypass intake valve 001 is opened; b. Monitor whether the preset pressure in the ash tank 2 reaches the set value When the value is reached, the bypass exhaust valve 002 is opened, and the intake valve 001 is closed at the same time; c. After the p...

Abstract

Provided is an anti-caking method for a powder ash pot. The method is used for a drilling platform powder ash pot, and prevents powder ashes from caking and blocking a pipeline when the pot is not used for a long time. The method comprises the following steps: a, switching on a system measuring and controlling device, starting preset measuring and controlling operation, at preset time, opening a bypass inlet valve; b, monitoring whether pressure in the preset powder ash pot reaches a preset value or not, if the pressure reaches the preset value, opening a bypass vent valve, and closing the inlet valve; c, at preset emptying time, closing the bypass vent valve, and starting the next loop operation. Beneficial effects of the method are that dry air replaces damp air in gaps of the powder ash particles at regular time, air proportion in the powder ashes is increased, and activity of the powder ashes is improved through the supplemented air, and through the vent valve, air in the pot is rapidly discharged, so as to disperse humidity, and prevent caking.

Description

technical field [0001] The invention is used for the ash scattered tank of the drilling platform to prevent the agglomeration from blocking the pipeline when the ash tank is not used for a long time. Background technique [0002] The ash tank of the drilling platform is out of service during non-drilling operations or long-distance towing, and the cement or bentonite powder in the lower part of the ash tank will agglomerate due to the accumulation of water vapor during the outage period. In severe cases, the conveying system of the ash tank cannot blow away the agglomerated cement or bentonite, so that the agglomerated material is blocked in the pipeline, so that the material in the ash tank cannot be transported to the slurry mixing site. Once this situation occurs, the platform operator must open the ash tank manhole and disassemble the pipeline of the conveying system for manual cleaning, resulting in a lot of unnecessary manual labor. Contents of the invention [0003...
