Description

A deep well solid-liquid mixture cleaning device Technical Field

[0001] This invention belongs to the field of deep mine waste treatment technology, and specifically relates to a deep well solid-liquid mixture cleaning device. Background Technology

[0002] Mine drilling technology is a crucial technology in the exploration and development of oil and gas resources. Currently, the drilling process generates waste such as drill cuttings, contaminated waste fluids, and packaging materials. Among these, the treatment of drill cuttings, especially those from deep wells, is a significant challenge. In the past, most of this waste was dumped into the ocean or buried underground. Such waste disposal methods no longer meet the requirements of the new era's eco-friendly economic development model, highlighting the significant contradiction between the rapidly developing mining industry and the long-standing lag in waste treatment technology.

[0003] Currently, downhole waste treatment operations primarily utilize negative pressure vacuum systems to process waste. During the vacuuming process, the motor of the negative pressure vacuum system rotates at high speed, drawing in air through the suction inlet and creating a vacuum in the dust chamber. Dust enters the filter bag inside the dust chamber through the suction pipe, where it is retained, thus adsorbing drill cuttings. To maximize the vacuuming area during downhole operations, a rotating mechanism is often incorporated into the suction head. However, the rotating mechanism of negative pressure vacuum systems generally does not use a pneumatic motor because pneumatic motors are difficult to control, and the suction pipe is prone to tangling. Rotary cylinders, on the other hand, have limit positions and are easier to control; therefore, rotary cylinders are commonly used in vacuum systems.

[0004] However, due to the limited space and large area covered by residue in deep well operations, the rotation angle of common suction head rotating mechanisms is insufficient, resulting in a small suction range, low efficiency, and difficulty in achieving task targets. Furthermore, negative pressure dust collection devices are generally used for deep well operations with a large amount of solid residue, and their efficiency is low for common solid-liquid mixtures and conditions with a high liquid content. To address these shortcomings and solve the practical problems of varying rotation angles of rotary cylinders and the difficulty in handling solid-liquid mixtures and residues with a high liquid density under common working conditions, a device capable of cleaning solid-liquid mixtures in deep wells is needed. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by proposing a novel deep-well solid-liquid mixture cleaning device. This device can not only recover solid waste but also freeze and recover liquid waste. It can handle solid-liquid mixtures and conditions with a high proportion of liquid, has high working efficiency, and enables the deep-well waste cleaning device to adapt to cleaning conditions with a wider range of waste states.

[0006] To achieve the above objectives, the present invention provides a deep well solid-liquid mixture cleaning device, including a propulsion mechanism, an extraction mechanism, a recovery mechanism, and a support mechanism;

[0013] The rotary cylinder is fixedly installed at the bottom of the extraction mechanism. The output shaft of the rotary cylinder extends vertically upward into the interior of the extraction mechanism. The first pulley is installed on the output shaft of the rotary cylinder. The bearing is fixedly installed at the bottom of the extraction mechanism via a bearing seat. The rotating shaft is rotatably connected to the bearing. One end of the rotating shaft extends into the interior of the extraction mechanism and is fixedly installed on the second pulley. The other end extends out of the bottom of the extraction mechanism and is connected to the rotating rod. A belt is wound around the outer sides of the first pulley and the second pulley.

[0014] Both the rotating rod and the fixed rod are L-shaped structures. One end of the rotating rod is connected to the rotating shaft, and the other end is slidably connected to the annular frame. One end of the fixed rod is fixed to the extraction mechanism, and the other end is fixed to the annular frame.

[0015] One end of the flexible fabric is fitted onto the rotating rod, and the other end is fitted onto the fixed rod;

[0016] A circular groove is provided along the inner wall of the annular frame. The groove is located inside the bottom edge of the annular frame, and the end of the rotating rod that is not connected to the rotating shaft is slidably connected to the groove.

[0017] A heating resistance wire is embedded in the bottom of the ring-shaped frame, and the heating resistance wire is the heating component.

[0018] Furthermore, the refrigeration assembly includes a liquid nitrogen tank, piping, and nozzles;

[0019] The liquid nitrogen tank is fixedly installed on the support mechanism, and the two ends of the pipeline are respectively connected to the liquid nitrogen tank and the nozzle. The nozzle is fixedly installed on the inner wall of the annular frame.

[0020] Furthermore, the flexible fabric is a foldable ring structure with multiple supporting bones inside. The multiple supporting bones are stacked one on top of the other. One end of the multiple supporting bones is hinged to the bottom of the fixed rod with a vertical bar by a pin, and the other end is fixedly installed in the flexible fabric at an equal angle along the pin.

[0021] Furthermore, the actuating mechanism includes a hydraulic rod, a balance bar, and a slide rail;

[0022] The hydraulic rod and the slide rail each have two identical structures, and the two hydraulic rods and the two slide rails are symmetrically fixed to the top of the support mechanism;

[0023] The hydraulic rods are symmetrically arranged, and their push rods are connected through the balance bar. The balance bar is perpendicular to the push rods of the two hydraulic rods.

[0024] The push rods of the two hydraulic rods are respectively fixedly mounted on the two slide rails via sliders.

[0025] Furthermore, the extraction mechanism includes a telescopic sleeve;

[0026] The telescopic sleeve is fixed to the bottom of the balance bar. The telescopic sleeve is a multi-stage stepped sleeve with the diameter decreasing from top to bottom. The top of the lower sleeve is fitted onto the bottom of the upper sleeve, and the lower sleeve can extend and retract within the upper sleeve.

[0027] Furthermore, the wall of each stage of the casing has a matching vertical groove, and the groove of the lower casing and the groove of the upper casing are connected by a horizontally set roller.

[0028] Furthermore, the support mechanism also includes sensors;

[0029] The sensor is fixedly mounted on the support mechanism and is used to collect the displacement of the extraction mechanism and send control signals to the extraction mechanism.

[0030] The beneficial effects of this invention are:

[0031] First, the recycling mechanism of the present invention has a recycling component and a heating component. The recycling component can surround the solid-liquid mixture inside it, and the heating component can heat the ground to detach the frozen liquid waste from the ground. The support mechanism includes a freezing component, which can freeze the liquid waste in the recycling component into a solid. It can not only recycle solid waste, but also recycle liquid waste after freezing. It can handle solid-liquid mixed states and working conditions with more liquid. It has high working efficiency and can make the deep well waste cleaning device adapt to cleaning working conditions with more waste states.

[0032] Secondly, the rotary cylinder of the present invention is fixedly installed at the bottom of the extraction mechanism. The output shaft of the rotary cylinder extends vertically upward into the interior of the extraction mechanism. The first pulley is installed on the output shaft of the rotary cylinder.

One end of the rotating shaft extends into the interior of the extraction mechanism and is fixedly installed on the second pulley. The other end extends out of the bottom of the extraction mechanism and is connected to the rotating rod. The outer sides of the first pulley and the second pulley are wrapped with belts. By using the rotary cylinder to connect with the pulley group, the rotation angle can be amplified while fully adapting to the phenomenon of slippage of the pulley when the output element is overloaded.

[0033] Third, the ring frame of the present invention is in contact with the ground, which can directly wrap the waste inside the ring frame. The waste coverage area is large, which can adapt well to the working space in deep wells.

[0034] Fourth, the flexible fabric of the present invention has a foldable ring structure with multiple supporting bones inside. The multiple supporting bones are stacked on top of each other. One end of the multiple supporting bones is hinged to the bottom of the fixed rod with a vertical bar by a pin. The other end of the multiple supporting bones is fixedly installed in the flexible fabric at equal angles along the pin. The ring size formed by the inner diameter and outer diameter of the flexible fabric matches the length of the horizontal bar of the fixed rod, which can maximize the recycling of waste at the bottom of the deep well.

[0035] Fifth, the support mechanism of the present invention is equipped with sensors that can collect the distance of the extraction mechanism to the bottom opening of the mounting frame and send control signals to the extraction mechanism to control its operation; sensors are installed on the ring frame, which are respectively connected to the motor, rotary cylinder, liquid nitrogen freezing assembly and heating resistance wire power supply, to detect the contact between the recovery mechanism and the deep well ground and transmit signals to the motor and liquid nitrogen freezing assembly, control the motor to stop working, control the liquid nitrogen freezing assembly to spray liquid nitrogen to freeze the liquid waste, and transmit signals to the heating resistance wire power supply and rotary cylinder in sequence. The heating resistance wire power supply heats the deep well ground, causing the frozen waste to detach from the ground, and then controls the working cylinder to start working, collecting the frozen waste onto the flexible fabric, so that the residue cleaning work can be completed without any manual operation steps during the operation;

[0036] Sixth, the pushing mechanism, extraction mechanism and recycling mechanism of the present invention are installed in the support mechanism, which is compact, highly practical and easy to manufacture. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0044] As shown in Figure 1, the present invention provides a deep well solid-liquid mixture cleaning device, which can recycle and clean both solid and liquid waste in deep wells. The cleaning device includes a pushing mechanism 1, an extraction mechanism 2, a recycling mechanism 3, and a supporting mechanism 4. The support mechanism 4 is a frame structure. The pushing mechanism 1 is located on top of the support mechanism 4. One end of the pushing mechanism 1 is fixed to the top surface of the support mechanism 4, and the bottom of the other end is equipped with the extraction mechanism 2. The pushing mechanism 1 has a horizontal telescopic structure, and the extraction mechanism 2 can move along the telescopic direction of the pushing mechanism 1 under the drive of the pushing mechanism 1. The bottom of the extraction mechanism 2 is equipped with a recycling mechanism 3. The extraction mechanism 2 has a vertical telescopic structure, and the recycling mechanism 3 can move along the vertical direction of the extraction mechanism 2 under the drive of the extraction mechanism 2. The support mechanism 4 has a freezing component, which freezes the liquid waste in the recycling mechanism 3 through pipes and nozzles. The recycling mechanism 3 has a heating component, which can slightly heat the frozen liquid waste, causing the frozen liquid waste to detach from the ground and then be recycled by the recycling mechanism 3. Solid waste can be directly recycled by the recycling mechanism 3. Then, the extraction mechanism 2 drives the recycling mechanism 3 to rise, and the pushing mechanism 1 transports the recycling mechanism 3 to the waste recycling area.

[0045] The support structure 4 includes an installation frame 40, a waste bin 41, a sensor 42, and a liquid nitrogen freezing assembly 43.

[0046] The mounting frame 40 is a rectangular structure with two vertically connected support rods at its top and bottom, arranged symmetrically. A bottom plate is located at the bottom of the mounting frame 40, on one side of the support rods. A waste bin 41 is mounted on the bottom plate, positioned near the support rods. An opening is located at the bottom of the mounting frame 40, on one side of the support rods, for the extraction mechanism 2 and the recycling mechanism 3 to pass through. A sensor 42 is fixedly mounted on one of the support rods to collect the distance the extraction mechanism 2 travels to the bottom opening of the mounting frame 40 and to send a control signal to the extraction mechanism 2, controlling its operation.

[0047] The liquid nitrogen freezing assembly 43 includes a liquid nitrogen tank, pipelines, and nozzles. The liquid nitrogen tank is fixedly mounted on the bottom frame of the mounting frame 40. The two ends of the pipeline are connected to the liquid nitrogen tank and the nozzle, respectively. The nozzle is fixedly mounted on the recovery mechanism 3 and is used to freeze the liquid waste in the recovery mechanism 3.

[0048] As shown in Figure 2, the pushing mechanism 1 includes a solenoid valve 10, a hydraulic rod 11, a hydraulic pipe 12, a balance bar 13, and a slide rail 14.

[0049] Two hydraulic rods 11 and two slide rails 14 are structurally identical. The two hydraulic rods 11 and two slide rails 14 are symmetrically fixed to the top of the mounting frame 40, with the two slide rails 14 positioned above the bottom opening of the mounting frame 40. The cylinder of the hydraulic rod 11 is fixedly mounted on the top of the mounting frame 40, and the push rod of the hydraulic rod 11 faces the bottom opening of the mounting frame 40. The two ends of the hydraulic pipe 12 are connected to the two side chambers of the hydraulic rod 11 for oil supply. A solenoid valve 10 is connected to the hydraulic pipe 12 to control the hydraulic rod 11, changing the internal pressure of the cylinder and driving the push rod of the hydraulic rod 11 to move laterally. The push rods of the symmetrically arranged hydraulic rods 11 are connected by a balance bar 13, which is perpendicular to the two hydraulic rods 11 to ensure smooth movement of the push rods. The push rods of the two hydraulic rods 11 are fixedly mounted on the two slide rails 14 by sliders. The extension and retraction of the hydraulic rods 11 drives the sliders to move along the slide rails 14.

[0050] As shown in Figure 3, the extraction mechanism 2 includes a motor 20, a coupling 21, a first nut mounting base 22, a lead screw assembly 23, a second nut mounting base 24, and a telescopic sleeve 25.

[0051] The telescopic sleeve 25 is a multi-stage stepped sleeve, with the diameter decreasing sequentially from top to bottom. The top of the lower sleeve is fitted over the bottom of the upper sleeve, allowing the lower sleeve to extend and retract within the upper sleeve. The motor 20, coupling 21, first nut mounting seat 22, lead screw assembly 23, and second nut mounting seat 24 are all located inside the telescopic sleeve 25.

[0052] Preferably, the telescopic sleeve 25 of this embodiment has a three-stage stepped sleeve, and the sleeve wall of each stage has a matching vertical groove. The top sleeve has a groove at the bottom, the middle sleeve has grooves at the top and bottom, and the bottom sleeve has a groove at the top. The grooves of the lower sleeve and the upper sleeve are connected by horizontally arranged rollers. The length of the groove matches the telescopic stroke of the telescopic sleeve 25.

[0053] The uppermost sleeve is fixedly installed at the bottom of the balance bar 13. The first-stage sleeve has two layers of partitions inside. The motor 20 is fixedly installed on the upper partition. The output shaft of the motor 20 is connected to the lower lead screw assembly 23 through the coupling 21.

[0054] The lead screw assembly 23 includes a first nut, a second nut, a third nut, and a lead screw. The first nut is fixed in a first nut mounting seat 22, which is fixedly mounted on the lower partition of the uppermost sleeve. A partition is located inside the middle sleeve. A second nut mounting seat 24 is fixedly mounted on the partition of the middle sleeve, and the second nut is fixedly mounted on the second nut mounting seat 24. One end of the lead screw passes through the first nut and connects to the coupling 21, while the other end extends into the middle sleeve and screws into the second nut.

[0055] The extraction mechanism 2 in this embodiment also includes a third nut mounting seat (not shown in Figure 3). There is a partition inside the bottommost sleeve. The third nut mounting seat is installed on the partition inside the bottommost sleeve. The third nut is installed in the third nut mounting seat. The lead screw passes through the first nut and the second nut in sequence and is screwed into the third nut. The lead screw has a limiting structure to prevent it from detaching from the third nut.

[0056] The bottom of the lowest sleeve has a base plate for mounting the recycling mechanism 3. The motor 20 rotates clockwise or counterclockwise, causing the lead screw to rotate clockwise or counterclockwise through the first, second, and third nuts. This, in turn, moves the middle and lowest sleeves up and down along the slide groove. When moving upwards, the recycling mechanism 3 moves upwards through the bottom opening of the mounting frame 40; when moving downwards, the recycling mechanism 3 moves downwards through the bottom opening of the mounting frame 40 to the waste position.

[0057] As shown in Figures 4 and 5, the recycling mechanism 3 includes a first pulley 30, a rotary cylinder 31, a second pulley 32, a bearing 33, a rotating shaft 34, a rotating rod 35, an annular frame 36, a fixed rod 37, and a flexible fabric 38.

[0058] A rotary cylinder 31 is fixedly mounted on the base plate of the lowest sleeve. The rotary cylinder 31 is powered by an external air source and can rotate clockwise and counterclockwise. The output shaft of the rotary cylinder 31 extends vertically upwards into the interior of the lowest sleeve, and a first pulley 30 is mounted on the output shaft. A bearing 33 is fixedly mounted on the base plate of the lowest sleeve via a bearing seat. A rotating shaft 34 is rotatably connected to the bearing 33. One end of the rotating shaft 34 extends into the interior of the lowest sleeve, and the other end extends below the base plate of the lowest sleeve and is connected to a rotating rod 35. A second pulley 32 is fixedly mounted on the rotating shaft 34 located inside the lowest sleeve. The center surfaces of the first pulley 30 and the second pulley 32 are coplanar. A belt is wound around the outside of the first pulley 30 and the second pulley 32. The rotary cylinder 31 drives the first pulley 30 to rotate, which in turn drives the second pulley 32 to rotate. The rotation of the second pulley 32 drives the rotating rod 35 to rotate.

[0059] Both the rotating rod 35 and the fixed rod 37 are L-shaped structures. One end of the rotating rod 35 is connected to the rotating shaft 34, and the other end is slidably connected to the annular frame 36. One end of the fixed rod 37 is fixed to the bottom plate of the lowest sleeve, and the other end is fixed to the annular frame 36, located directly above the part of the rotating rod 35 that is slidably connected to the annular frame 36. An annular groove is provided around the inner wall of the annular frame 36, located inside the bottom edge of the annular frame 36. The end of the rotating rod 35 that is not connected to the rotating shaft 34 is slidably connected to the annular groove on the annular frame 36 via a slider or roller.

[0060] The nozzle of the liquid nitrogen freezing assembly 43 is fixedly installed on the inner wall of the annular frame 36.

[0061] The flexible fabric 38 has a foldable ring structure with multiple supporting bones inside. These supporting bones are stacked one on top of the other. One end of each supporting bone is hinged to the bottom of the vertical rod of the fixed rod 37 via a pin. The other ends of the supporting bones are fixed at equal angles to the flexible fabric 38 along the pin. The annular dimension formed by the inner and outer diameters of the flexible fabric 38 matches the length of the horizontal rod of the fixed rod 37, enabling maximum recovery of waste from the bottom of the deep well. One end of the flexible fabric 38 is fitted onto the rotating rod 35, and the other end is fitted onto the fixed rod 37. The rotating rod 35 rotates clockwise or counterclockwise under the drive of the rotating shaft 34. Taking the state shown in Figure 5 as an example, when the rotating rod 35 rotates clockwise, the flexible fabric 38 unfolds, allowing the frozen waste separated from the ground to be collected on the flexible fabric 38. The height difference between the rotating rod 35 and the fixed rod 37 matches the height of the multiple supporting bones stacked vertically and is smaller than the size of the waste. When the rotating rod 35 rotates counterclockwise, the flexible fabric 38 is retracted, and the waste is wrapped inside the annular frame 36 after contacting the ground. A heating resistance wire is embedded in the bottom of the annular frame 36. The heating resistance wire is connected to an external power source to heat the ground. The frozen liquid waste is separated from the ground through heat conduction. After separation, the flexible fabric 38 unfolds due to the rotating rod 35, and the waste is collected on the flexible fabric 38.

[0062] Preferably, a sensor is also installed on the annular frame 36. This sensor is connected to the motor 20, the rotary cylinder 31, the liquid nitrogen freezing assembly 43, and the heating resistance wire power supply, respectively. It is used to detect when the recovery mechanism 3 comes into contact with the deep well ground and transmit the signal to the motor 20 and the liquid nitrogen freezing assembly 43. The motor 20 is controlled to stop working, and the liquid nitrogen freezing assembly 43 is controlled to spray liquid nitrogen to freeze the liquid waste. The signal is then transmitted to the heating resistance wire power supply and the rotary cylinder 31 in sequence. The heating resistance wire power supply heats the deep well ground, causing the frozen waste to detach from the ground. Then, the working cylinder 31 is controlled to start working and collect the frozen waste onto the flexible fabric 38.

[0063] Example:

[0064] Before the start of the processing work, the deep well solid-liquid mixture cleaning device of the present invention is in the following working state: the extraction mechanism 2 is in the initial state, the telescopic sleeve 25 is not extended, the flexible fabric 38 of the recovery mechanism 3 is in the retracted state, the rotating rod 35 is rotated to directly below the fixed rod 37, and the hydraulic rod 11 of the pushing mechanism 1 is retracted.

[0065] Taking the recycling of waste containing liquid as an example, the method includes the following steps:

[0066] Step 1: The processing work begins. The hydraulic rod 11 is moved laterally by the solenoid valve 10, which in turn drives the slider to slide along the slide rail 14, and controls the balance bar 13 to reach the position above the working well.

[0067] Step 2: After the balance bar 13 reaches the designated working position, the extraction mechanism 2 performs a stretching motion, driving the internal lead screw assembly 23 to rotate, thereby extending the telescopic sleeve 25 and driving the recovery mechanism 3 to the bottom of the well.

[0068] Step 2.1: Sensor 42 detects that the telescopic sleeve 25 has moved into position by the push mechanism 1, and sensor 42 sends a signal to motor 20, and motor 20 starts working.

[0069] Step 2.2: The rotational motion of the motor 20 is transmitted to the lead screw through the coupling 21, driving the lead screw to rotate, thereby causing the telescopic sleeve 25 to move vertically downward. The telescopic sleeve 25 drives the bottom recycling mechanism 3 to gradually move down until the bottom of the recycling mechanism 3 contacts the bottom of the working well, surrounding the waste in the annular frame 36, and sending a control signal to the motor 20 through the sensor on the recycling mechanism 3 to control the motor 20 to stop working.

[0070] Step 3: The liquid nitrogen freezing component 43 freezes the liquid waste, and the heating resistance wire heats the ground until the frozen liquid waste separates from the ground. The rotary cylinder 31 starts to drive the rotary rod 35 to rotate and collect the frozen waste.

[0071] Step 3.1: The sensor of the ring frame 36 sends control signals to the liquid nitrogen freezing component 43 and the heating resistance wire power supply in sequence. The nozzle of the liquid nitrogen freezing component 43 sprays liquid nitrogen into the liquid waste inside the ring frame 36. Then, the heating resistance wire embedded in the bottom of the ring frame 36 heats the ground until the frozen waste separates from the ground.

[0072] Step 3.2: The rotary cylinder 31 drives the first pulley 30 to rotate, which in turn drives the second pulley 32 to rotate via the belt. The second pulley 32 transmits the torque to the rotating shaft 34.

[0073] Step 3.3: The rotating shaft 34 performs a circular motion, which drives the rotating rod 35 to rotate in the specified direction and unfolds the flexible fabric 38. The unfolding action of the flexible fabric 38 collects the frozen waste on it, which can recover the waste at the bottom of the deep well to the greatest extent.

[0074] Step 4: After the flexible fabric 38 is unfolded into place, the motor 20 controls the lead screw to rotate in the opposite direction of stretching, controls the telescopic sleeve 25 to retract, and drives the retraction mechanism 3 to move up to the designated position and then stop.

[0075] Step 5: Push mechanism 1 controls hydraulic rod 11 to retract, and move recycling mechanism 3 to directly above waste bin 41. Rotary cylinder 31 rotates in the opposite direction to step 3.2, causing rotating rod 35 to drive flexible fabric 38 to gather, and the collected frozen liquid and other solid waste fall into waste bin 41, completing the cleaning work.

[0076] Step 6: Repeat steps 1 to 5 to complete the waste cleaning work in other locations.
