Description

Technical Field

[0001] The utility model relates to the technical field of sewage recovery equipment, in particular to a sewage recovery device for drilling engineering. Background Art

[0002] Drilling wastewater is a special type of industrial wastewater generated during the drilling process. It contains toxic and harmful substances such as petroleum, heavy metal salts, non-degradable organic matter, silt, bacteria, etc. It is complex, variable, and dispersed, with strong pungent and rancid odors. Most of the wastewater collection devices used in existing drilling engineering construction directly use mud pumps to suck out the wastewater flowing out of the wellbore. Since the wastewater contains more solid particles such as silt, rock cuttings, etc., it is easy to cause the mud pump system to be blocked, thereby delaying work. In addition, during the pumping process, it is inevitable that wastewater will overflow around the wellbore and pollute the working environment.

[0003] In this regard, after searching, publication number CN217645965U discloses a sewage recovery device for drilling projects, including a wellbore and an outside well collection pool, a drill pipe is arranged inside the wellbore, a back-blocking cover is arranged on the outer wall of the top end of the drill pipe, a scraper connected to the outer wall of the drill pipe is arranged directly above the back-blocking cover, and the outside well collection pool is arranged around the periphery of the wellbore; by designing back-blocking covers, scrapers, high-pressure air flow nozzles, outside well collection pools, primary vibrating screens, secondary vibrating screens and other components around the wellbore of traditional drilling projects, it can realize the recovery of drilling sewage after filtration to avoid clogging of mud pumps, and at the same time, the device plays a good role in collecting overflow dirt around the wellhead, which can improve the cleanliness of the wellhead working environment and is conducive to safe construction.

[0004] The above technology discloses a sewage recovery device for drilling projects. By means of an outside well collection pool and other structures arranged on the outside of the wellbore and embedded in the ground, the sewage overflowing from between the wellbore and the drill pipe can be prevented from directly overflowing outwards. There is no need to use a mud pump for extraction, and the mud pump is also avoided from being easily blocked. However, it still has the following shortcomings: 1. Its collection and recovery method, which is integrally fixed on the outside of the wellbore and on the ground, cannot be conveniently assembled on site for flexible assembly and disassembly, has unsatisfactory flexibility of use, and is difficult to recycle. In view of this, we propose a sewage recovery device for drilling projects. Utility Model Content

[0027] The bottom inner walls of the two assembly boxes 5 are both embedded with assembly sleeve components that are compatible with the outer side of the wellbore 100; the assembly sleeve components include a semicircular sleeve 9 embedded and fixed on the bottom inner wall of the corresponding assembly box 5, wherein the bottom of the semicircular sleeve 9 is flush with the bottom of the assembly box 5, the two semicircular sleeves 9 match, and a semicircular rubber sleeve 10 is bonded and fixed in the semicircular sleeve 9, and the two semicircular rubber sleeves 10 are both compatible with the outer side of the wellbore 100, and the top of the U-shaped seat 1 is movably nested with a support ball 13 that is in rolling contact with the bottom of the corresponding semicircular sleeve 9, and the support ball 13 is set to perform bottom movable support to prevent falling and bending; the semicircular sleeve 9 and the semicircular rubber sleeve 10 are matched, and when the two assembly boxes 5 are nearly assembled, the two semicircular sleeves 9 and the two semicircular rubber sleeves 10 are driven to be assembled and sheathed on the outer side of the wellbore 100, and the semicircular rubber sleeve 10 is used to shield the sewage overflowing from the upper part;

[0028] The two assembly boxes 5 are both installed with a vibration filter slag guide assembly adapted to the outer side of the wellbore 100. The two assembly boxes 5 have a slag discharge hole 7 with an inclined bottom inner wall on one side.

The wireless remote control module and the external remote control cooperate to remotely control the synchronous control switch to turn on.

[0030] The method of using this embodiment is as follows: the four universal wheels 17 are provided to facilitate personnel to flexibly move the device. When sewage is recovered during drilling work, the device is moved to the wellbore 100, and the upper part of the wellbore 100 is located in the U-shaped seat 1 and between the two assembly boxes 5. At this time, the two drive motors 3 are controlled by the synchronous control switch to start in the forward direction. The two drive motors 3 drive the two screws 15 to rotate. The rotation of the two screws 15 drives the two moving seats 16 to move close to each other. The moving seats 16 slide horizontally on the corresponding two transverse guide rods 14. The two moving seats 16 drive the two assembly boxes 5 to move close to each other for assembly work. When the two assembly boxes 5 are close to each other, they drive the two semicircular sleeves 9 to be close to each other. The two semicircular sleeves 9 drive the two semicircular rubber sleeves 10 to be assembled and wrapped in the wellbore. 100, the semicircular rubber sleeve 10 is used to shield the sewage overflowing from the upper part. When the two assembly boxes 5 move close to each other, they also drive the two inclined filter plates 6 to be assembled and wrapped on the outside of the wellbore 100, so as to achieve the effect of convenient and flexible splicing on the outside of the wellbore 100. When it is not used and needs to be removed later, the two drive motors 3 are started in the reverse direction. Similarly, the movement direction of the two drive motors 3 is completely opposite to the above-mentioned forward start. At this time, the two assembly boxes 5 are transformed into repulsive separation, and the two semicircular sleeves 9 are driven to repel and separate, so as to achieve separation from the wellbore 100. Then, the device can be removed by the universal wheel 17. Through the movable cooperation, it can be automatically assembled and disassembled on the outside of the wellbore 100 on site, which is convenient for the convenient and flexible assembly and disassembly of the sewage recovery device on site, so as to facilitate its recycling and improve its flexibility of use.

[0031] After the sewage recovery device is assembled on the outside of the wellbore 100, when sewage overflows upward through the drill pipe and the space inside the wellbore 100 during drilling, the sewage overflowing from the top of the wellbore 100 will flow downward and fall on the two inclined filter plates 6, and the two vibrators 11 will be turned on. When the vibrators 11 vibrate, the hard vibration force will be transmitted to the corresponding inclined filter plates 6 to cause a slight high-frequency hard micro-vibration. The sewage is quickly filtered downward into the assembly box 5 through the hard-vibrated inclined filter plates 6, and the solid impurities in the sewage are blocked and filtered on the corresponding inclined filter plates 6. At this time, the hard vibration of the inclined filter plates 6 and their inclined setting can automatically vibrate the solid impurities outward and discharge them into the slag discharge holes 7, and then discharge them into the corresponding slag collecting box 4 through the slag discharge holes 7, thereby achieving the effect of filtering and recovering sewage and automatically discharging and collecting solid impurities. After use, the drain valve 12 is connected to the external collection box through an external pipeline, and the recovered sewage can be discharged by opening the drain valve 12.
