Description

Technical Field

[0001] This invention relates to the field of geological drilling waste slurry treatment technology, and in particular to a geological drilling waste slurry treatment and rapid water quality testing device. Background Technology

[0002] Centrifuges are devices that use centrifugal force to separate mixtures. They are widely used in the field of harmless treatment of geological drilling waste slurry. Geological drilling waste slurry typically refers to a mixed fluid containing bentonite, rock cuttings, oils, and various chemical treatment agents generated during geological drilling operations. It is characterized by high suspended solids, high viscosity, complex composition, and strong stability. If the waste slurry is discharged indiscriminately without treatment, or if it is not properly managed or treated, it will not only pollute the surrounding soil, surface water, and groundwater, but also disrupt the ecological balance, causing irreversible environmental damage. With the continuous deepening of the national green exploration and ecological environmental protection concepts, and the continuous improvement of environmental protection regulations, the standards for the harmless treatment of geological drilling waste slurry are becoming increasingly stringent, placing higher demands on the efficiency, energy consumption, and treatment effect of treatment equipment.

[0003] Currently, most geological drilling waste slurry solid-liquid separation operations use horizontal screw centrifuges (hereinafter referred to as horizontal screw centrifuges) as the core processing equipment. Horizontal screw centrifuges generate centrifugal force fields through the high-speed rotation of horizontal drums, causing the liquid phase in the waste slurry to be discharged and the solid phase to be retained, thereby achieving the purpose of solid-liquid separation.

[0004] However, traditional horizontal screw centrifuges occupy a large area, which is not conducive to the layout of limited spaces at drilling sites. The equipment is difficult to install and debug, and the separation effect is not good. The discharged liquid phase still has turbidity and the solid phase has a high water content, requiring additional treatment processes, which not only increases the treatment cost but also reduces the overall treatment efficiency. In addition, most centrifuges use manual sampling and offline testing to assess the quality of the clarified liquid. Operators collect samples from the outlet and send them to the laboratory for analysis. The process of sampling, testing, and feedback consumes a lot of time, making it impossible to reflect changes in the clarified liquid quality in real time. It is difficult to adjust the dosage of treatment agents such as de-colloidants, flocculants, and decolorizing agents, as well as parameters such as centrifuge speed and separation time in a timely manner, thus affecting the stability and compliance rate of waste slurry treatment and making it difficult to achieve precise control of the harmless treatment of waste slurry. Summary of the Invention

[0005] The purpose of this invention is to provide a geological drilling waste slurry treatment and water quality rapid testing device. This device performs real-time testing on the clear liquid separated from the centrifuge, which facilitates timely adjustment of the treatment agent dosage and centrifuge operating parameters by the staff.

The sealing end cap is installed on the top of the detection pool body; At least two probe protective sleeves are fixed in the sealed end cap; At least two water quality testing probes are respectively inserted into the corresponding probe protective sleeves, and the testing end of the water quality testing probe extends through the probe protective sleeve into the interior of the testing pool; The probe alternation drive mechanism is installed on the sealed end cover and is used to drive the two water quality detection probes to rise and fall alternately, so that when one of the water quality detection probes is inserted into the detection pool for monitoring, the other water quality detection probe is pulled out of the detection pool.

[0007] Preferably, the interior of the detection pool is provided with a buffer partition, which divides the interior of the detection pool into a pretreatment chamber near the centrifuge body and a detection chamber away from the centrifuge body; The bottom edge of the buffer partition and the bottom surface of the detection pool form a narrow channel connecting the pretreatment chamber and the detection chamber; The detection end of the water quality detection probe is located inside the detection cavity.

[0008] Preferably, the buffer baffle is provided with a flow guide surface on the side facing the pretreatment cavity, and the flow guide surface is a corrugated structure or a V-groove structure.

[0009] Preferably, at least two guide rods are vertically fixed inside the detection pool, and the buffer plate is slidably sleeved on the guide rods and fixed on the guide rods by positioning components; the gap width of the slit channel changes with the adjustment of the number of buffer plates used.

[0010] Preferably, the probe alternating drive mechanism includes a mounting base, the bottom end of which is fixedly connected to the sealing end cap; The drive motor is mounted on the top of the mounting base; The transmission gear is connected to the output end of the drive motor; Two rack sliding plates mesh with the two sides of the transmission gear, and the rack sliding plates are provided with snap-fit ​​grooves for fixing the water quality detection probe; A guide limiting plate is disposed on one side of the mounting base, and the rack sliding plate is slidably disposed on one side of the guide limiting plate; The protective shell is located on the outside of the guide limiting plate, and the protective shell has a wire through groove for the water quality detection probe wire to pass through.

[0011] Preferably, the centrifuge body includes a housing, which is fixed to the base; The drum is rotatably mounted inside the outer casing; The rotating shaft is fixed to the bottom end of the drum; The power source is located in the base and is connected to the rotating shaft for driving the drum to rotate; The top cover is connected to the outer shell.

[0012] Preferably, a stirrer is installed on the top cover, and when the top cover is closed, the stirrer extends into the interior of the drum.

[0013] Preferably, the top cover is provided with a transfer pipe, and the stirrer is connected to the transfer pipe; The agitator includes a sleeve, which is connected to the adapter tube; The first stirring blade is located at the bottom end of the sleeve; At least two second stirring blades are disposed on the sleeve and positioned above the first stirring blades; The first stirring blade and the second stirring blade are arranged alternately in the vertical direction.

[0014] Preferably, the top cover is provided with a washing tube, which extends into the gap between the drum and the outer shell when the top cover is closed.

[0015] Preferably, shock-absorbing feet are installed at the four bottom corners of the base; The shock-absorbing foot includes a square base plate; The vertical rod is fixed to the square base plate; The cylinder is fitted onto the outer wall of the vertical rod, and the top end of the cylinder is connected to the base; A damping ring is disposed between the cylinder and the vertical rod; The spring is sleeved on the outer wall of the cylinder, and the two ends of the spring abut against the base and the square base plate, respectively.

[0016] The geological drilling waste slurry treatment and rapid water quality testing device provided by this invention has the following beneficial effects: By equipping the centrifuge body with an online water quality monitoring module at the outlet, the water quality parameters of the separated clarified liquid can be monitored in real time, including color, suspended solids, chemical oxygen demand, salinity, etc. This assists operators in adjusting the dosage of treatment agents, such as degumming agents, flocculants, and decolorizing agents, as well as the centrifuge's operating parameters, such as speed and separation time, based on real-time monitoring data. The design of two water quality monitoring probes that alternately rise and fall allows one probe to be inserted into the detection chamber for monitoring while the other probe is pulled out of the detection chamber to enter standby or cleaning mode. By setting a time interval, the two probes periodically exchange working positions, effectively avoiding problems such as scaling and biofouling caused by the probes being immersed in the same liquid environment for a long time.

[0017] In some implementations, a buffer baffle divides the detection pool into a pretreatment chamber and a detection chamber, which are connected by a slit channel at the bottom. After the liquid enters the pretreatment chamber, it directly impacts the buffer baffle, and its kinetic energy is greatly dissipated. The entrained air bubbles burst here, and the buffered liquid slowly permeates into the detection chamber through the slit channel, making the detection chamber a calm and undisturbed low-disturbance zone. This reduces the impact of the violently moving fluid on the water quality detection probe and creates a suitable measurement environment for the detection probe. Attached Figure Description

Detailed Implementation

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0023] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, a geological drilling waste slurry treatment and rapid water quality testing device includes a base 1, a centrifuge body 2 installed on the base 1, and an online water quality testing module 3 configured at the liquid outlet end of the centrifuge body 2. The online water quality testing module 3 includes a testing tank 301, a sealing end cap 302, a probe protective sleeve 303, a water quality testing probe 304, and a probe alternating drive mechanism 5. The testing tank 301 is mounted on the base 1 and one side is connected to the liquid phase outlet of the centrifuge body 2. The sealing end cap 302 is installed on the top of the testing tank 301. At least two probe protective sleeves 303 are fixed in the sealing end cap 302. At least two water quality testing probes 304 are respectively inserted into the corresponding probe protective sleeves 303, and the testing end of the water quality testing probe 304 extends through the probe protective sleeve 303 into the interior of the testing tank 301. The probe alternating drive mechanism 5 is installed on the sealed end cover 302 and is used to drive the two water quality detection probes 304 to rise and fall alternately, so that when one water quality detection probe 304 is inserted into the detection pool 301 for monitoring, the other water quality detection probe 304 is pulled out from the detection pool 301.

[0025] Therefore, the detection tank 301 can be made of a transparent and corrosion-resistant material to facilitate observation of the internal liquid flow. The bottom of the detection tank 301 is embedded in the groove of the base 1. The side of the detection tank 301 near the centrifuge body 2 is connected to the liquid phase outlet of the centrifuge body 2 through the connecting flange pipe 4. The connecting flange pipe 4 is connected to the liquid outlet end of the centrifuge body 2 through a flange, which is convenient for disassembly and assembly. The probe protective sleeve 303 has a cylindrical structure and a sealing ring is provided on the inner wall to ensure that the water quality detection probe 304 forms a seal with the inside of the detection tank 301 after insertion, preventing liquid from overflowing. The water quality detection probe 304 can be configured as one or more combinations of a color probe, a suspended solids probe, a chemical oxygen demand probe, or a salinity probe as needed. By setting a time interval, the two probes alternate periodically, effectively avoiding problems such as probe scaling and bio-attachment caused by long-term immersion. It should be noted that as the water quality testing probe 304 moves upward along the probe protective sleeve 303, the flexible sealing ring in the probe protective sleeve 303 will clean away the impurities attached to the surface of the water quality testing probe 304.

[0026] In some embodiments, such as Figure 2 and Figure 3 As shown, a buffer partition 6 is provided inside the detection pool 301. The buffer partition 6 divides the interior of the detection pool 301 into a pretreatment chamber 7 on the side closer to the centrifuge body 2 and a detection chamber 8 on the side farther away from the centrifuge body 2. A slit channel 9 is formed between the bottom edge of the buffer partition 6 and the bottom surface of the detection pool 301, connecting the pretreatment chamber 7 and the detection chamber 8. The detection end of the water quality detection probe 304 is located inside the detection chamber 8.

[0027] Specifically, the buffer baffle 6 is made of corrosion-resistant stainless steel; the pretreatment chamber 7 is a high-disturbance zone, where the liquid directly impacts the buffer baffle 6 after entering, and the kinetic energy is greatly consumed, causing the bubbles to burst; the detection chamber 8 is a low-disturbance zone, where the liquid slowly seeps in through the narrow slit channel 9 at the bottom, providing a calm and interference-free measurement environment for the detection probe. In addition, an air outlet pipe is designed above the pretreatment chamber 7. Multiple air outlet pipes are evenly distributed on the sealing end cover 302. The air outlet pipes are designed to prevent gas accumulation from affecting the stability of the liquid level.

[0028] In some embodiments, such as Figure 3 As shown, a guide surface 11 is provided on the side of the buffer baffle 6 facing the pretreatment chamber 7. The guide surface 11 is a corrugated structure or a V-groove structure. Specifically, the guide surface 11 is designed with a corrugated or V-groove structure. Compared with a regular flat plate, the corrugated structure can buffer the impact of the water and guide the water flow to move smoothly down the wall. In another variant embodiment, the guide surface 11 adopts a V-groove structure, which can also achieve the functions of energy dissipation, bubble breaking and rectification.

[0029] In some embodiments, such as Figure 3 As shown, at least two guide rods 10 are vertically fixed inside the detection pool 301. The buffer plate 6 is slidably sleeved on the guide rod 10 and fixed on the guide rod 10 by the positioning member 12. The gap width of the slit channel 9 changes with the adjustment of the number of buffer plates 6 used. Specifically, there are two guide rods 10, symmetrically arranged on both sides of the detection pool 301; guide holes are opened at corresponding positions on the buffer partition 6, and the positioning part 12 is a set screw, which is tightened to fix the buffer partition 6 at the specified height of the guide rod 10; The gap width of the slit channel 9 is adjusted according to the different viscous slurry viscosities (the specific adjustment method is to change the number of buffer plates 6 used). For low-viscosity slurry, three buffer plates 6 are installed in parallel on the guide rod 10 to narrow the gap of the slit channel 9; for high-viscosity slurry, two buffer plates 6 are installed in parallel on the guide rod 10 to widen the gap of the slit channel 9.

[0030] In some embodiments, such as Figure 4 As shown, the probe alternating drive mechanism 5 includes a mounting base 501, a drive motor 502, a transmission gear 503, a rack and pinion sliding plate 504, a guide limiting plate 506, and a protective shell 507. The bottom end of the mounting base 501 is fixedly connected to the sealing end cover 302; the drive motor 502 is mounted on the top end of the mounting base 501; the transmission gear 503 is connected to the output end of the drive motor 502; two rack and pinion sliding plates 504 are respectively engaged on both sides of the transmission gear 503, and the rack and pinion sliding plates 504 are provided with snap-fit ​​grooves 505 for fixing the water quality detection probe 304; the guide limiting plate 506 is disposed on one side of the mounting base 501, and the rack and pinion sliding plates 504 are slidably disposed on one side of the guide limiting plate 506; the protective shell 507 is disposed on the outside of the guide limiting plate 506, and the protective shell 507 is provided with a wire through groove 508 for the wires of the water quality detection probe 304 to pass through. Specifically, the drive motor 502 is a stepper motor; a T-shaped slider is fixed to the back of the rack and pinion sliding plate 504, which cooperates with the T-shaped (strip-shaped) slide groove on the guide limit plate 506 to make the sliding smooth; the snap-fit ​​groove 505 has a U-shaped structure with a rubber pad on the inside. In addition, the water quality detection probe 304 can be fixed in the snap-fit ​​groove 505 by a clamp; the protective shell 507 is made of transparent plastic, which makes it easy to observe the internal operating status; the wire through groove 508 is a long strip hole, which facilitates the wire to be led out and does not affect the movement of the sliding plate; For example: the drive motor 502 rotates 180 degrees forward, causing one probe to descend and be inserted into the detection chamber 8, while the other probe rises and is pulled out; after a preset time (e.g., 30 minutes), the drive motor 502 rotates 180 degrees in reverse, and the two probes exchange positions. This cycle repeats to achieve automatic cleaning and alternating monitoring of the probes.

[0031] In some embodiments, such as Figure 7 and Figure 8 As shown, the centrifuge body 2 includes a shell 201, a drum 202, a rotating shaft 203, a power source 204, and a top cover 205. The shell 201 is fixed on the base 1. The drum 202 is rotatably disposed inside the shell 201. The rotating shaft 203 is fixed at the bottom end of the drum 202. The power source 204 is disposed in the base 1 and is connected to the rotating shaft 203 for driving the drum 202 to rotate. The top cover 205 is connected to the shell 201.

[0032] Specifically, the outer shell 201 is made of stainless steel with a polished inner wall; the outer shell 201 is fixedly connected to the base 1 via corner fittings, which are L-shaped and welded to the bottom of the outer shell 201, and connected to the base 1 via bolts; the drum 202 has a conical or cylindrical structure with filter holes on its wall, the hole diameter being 0.5-2mm; filter bags can be installed inside the drum 202 to intercept solid particles; the rotating shaft 203 is installed at the bottom of the outer shell 201 via a bearing seat, which contains a waterproof bearing and a mechanical seal to prevent liquid leakage; The power source 204 can be driven by a belt pulley. For example, a first pulley is installed at the bottom end of the rotating shaft 203 and a second pulley is installed at the bottom end of the power source 204. The first pulley and the second pulley are connected by a conveyor belt, thereby providing power for the rotation of the drum 202. The top cover 205 and the outer shell 201 are connected by a hinge. In addition, the top cover 205 and the outer shell 201 can also be connected by a cylinder to provide power for automatic opening and closing.

[0033] In some embodiments, such as Figure 7 As shown, a stirrer 13 is installed on the top cover 205. When the top cover 205 is closed, the stirrer 13 extends into the interior of the drum 202. It should be noted that the agitator 13 provides auxiliary disturbance to the waste slurry, preventing the material from accumulating near the feed inlet and improving separation efficiency. In particular, for high-concentration waste slurry, the presence of the agitator 13 can effectively disrupt the "plunger flow" formed in the center of the drum 202, promoting solid-liquid separation.

[0034] In some embodiments, such as Figure 6 As shown, the top cover 205 is provided with a transfer pipe 14, and the stirrer 13 is connected to the transfer pipe 14; The stirrer 13 includes a sleeve 131, a first stirring blade 132, and a second stirring blade 133. The sleeve 131 is connected to the adapter pipe 14. The first stirring blade 132 is disposed at the bottom end of the sleeve 131. At least two second stirring blades 133 are disposed on the sleeve 131 and located above the first stirring blade 132. The first stirring blade 132 and the second stirring blade 133 are staggered in the vertical direction. Specifically, the transfer pipe 14 is a stainless steel pipe, which is welded and fixed to the top cover 205. The transfer pipe 14 serves as a feed pipe and is used to connect to the external feed pipe. The sleeve 131 is fitted onto the outer wall of the transfer pipe 14 and fixed by set screws for easy disassembly and replacement. The first stirring blade 132 is a four-blade type, evenly distributed at 90 degrees, with a blade inclination angle of 30-45 degrees. The second stirring blade 133 is located 50-80 mm above the first stirring blade 132, with a blade inclination angle of 15-30 degrees. In addition, the edges of the stirring blades can be designed to be serrated, which helps to break up agglomerated particles.

[0035] In some embodiments, such as Figure 7 As shown, a washing tube 206 is disposed in the top cover 205. When the top cover 205 is closed, the washing tube 206 extends into the gap between the drum 202 and the outer casing 201. Specifically, the washing tube 206 is a cylindrical tube that can be inserted into the gap between the drum 202 and the outer shell when the top cover 205 is closed. A row of spray holes is machined on the side of the washing tube 206 near the drum 202. The diameter of the spray holes is 1-3mm and the spacing between the holes is 10-20mm. After connecting to an external water source, high-pressure water is sprayed out from the spray nozzle to rinse the outer wall of the drum 202 and remove the attached solid particles. In addition, a solenoid valve can be installed at the water inlet of the washing pipe 206.

[0036] In some embodiments, such as Figure 9 As shown, shock-absorbing feet 15 are installed at the four corners of the bottom of the base 1; The shock-absorbing foot 15 includes a square base plate 151, a vertical rod 152, a cylinder 153, a damping ring 154, and a spring 155; the vertical rod 152 is fixed on the square base plate 151; the cylinder 153 is sleeved on the outer wall of the vertical rod 152, and the top end of the cylinder 153 is connected to the base 1; the damping ring 154 is disposed between the cylinder 153 and the vertical rod 152; the spring 155 is sleeved on the outer wall of the cylinder 153, and the two ends of the spring 155 abut against the base 1 and the square base plate 151 respectively; Specifically, the square base plate 151 is made of steel plate with through holes at the four corners and rubber anti-slip pads attached to the bottom surface; the cylinder 153 is a hollow cylinder, and the top of the cylinder 153 is connected to the base 1 by bolts, so that the shock-absorbing foot 15 is a replaceable installation method; the damping ring 154 is made of wear-resistant rubber or polyurethane material, which plays a role in guiding and absorbing high-frequency vibrations; the spring 155 is a cylindrical helical compression spring, and the pre-compression of the spring 155 is adjustable to adapt to equipment of different weights; The vibration of the equipment is transmitted to the cylinder 153 through the base 1. The damping ring 154 between the cylinder 153 and the vertical rod 152 absorbs the high-frequency vibration, while the spring 155 buffers the low-frequency vibration, thus isolating the vibration generated by the centrifuge body 2 from interfering with the online water quality detection module 3.

[0037] The working principle of this application is illustrated below with a preferred embodiment: The filter bag is installed inside the drum 202, and then the top cover 205 is closed. When the equipment is running, the power source 204 in the base 1 drives the rotating shaft 203 to rotate, and the rotating shaft 203 drives the drum 202 to rotate at high speed in the outer shell 201. The waste slurry to be treated enters the high-speed rotating drum 202 from the conversion pipe 14 at the top of the centrifuge body 2. Under the action of centrifugal force, the denser solid particles are thrown onto the filter bag on the inner wall of the drum 202 to form a filter cake, while the less dense clear liquid is discharged from the liquid outlet of the centrifuge body 2 through the drum 202. When the top cover 205 is closed, the agitator 13 installed on the top cover 205 extends into the interior of the drum 202 as the top cover 205 is closed. The first agitator blade 132 and the second agitator blade 133 of the agitator 13 are arranged alternately in the vertical direction, which generates auxiliary disturbance to the waste slurry when the drum 202 rotates. After centrifugation, the clear liquid enters the online water quality detection module 3 from the outlet end of the centrifuge body 2 through the connecting flange pipe 4. The clear liquid first enters the pretreatment chamber 7 of the detection tank 301. Due to the certain flow rate and disturbance of the incoming liquid, the liquid directly impacts the guide surface 11 on the buffer baffle 6. The corrugated structure or V-groove structure on the guide surface 11 greatly consumes the kinetic energy of the liquid, slowing down the high-speed inflow liquid. During the liquid impact, the air bubbles entrained here burst. The buffered liquid slowly penetrates into the detection chamber 8 through the narrow channel 9 between the bottom of the buffer baffle 6 and the bottom surface of the detection tank 301. The detection end of the water quality detection probe 304 is immersed in the clear liquid in the detection chamber 8 to monitor water quality parameters such as color, suspended solids, chemical oxygen demand, and salinity in real time. When the probe alternating drive mechanism 5 is working: the drive motor 502 drives the transmission gear 503 to rotate, and the transmission gear 503 drives the rack sliding plates 504 on both sides to move in the opposite direction, so that one water quality detection probe 304 descends and inserts into the detection chamber 8 for monitoring, while the other water quality detection probe 304 rises and is pulled out of the detection chamber 8 to enter the standby or cleaning state. When the centrifuge body 2 is working, the equipment vibration is transmitted to the cylinder 153 through the base 1. The damping ring 154 between the cylinder 153 and the vertical rod 152 absorbs high-frequency vibration, while the spring 155 buffers low-frequency vibration. After the waste liquid treatment is completed, when the top cover 205 is closed, the washing pipe 206 configured on the top cover 205 extends into the gap between the drum 202 and the outer casing 201. After the external water source is connected, the spray holes on the washing pipe 206 rinse the outer wall of the drum 202.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
