Description

Technical Field

[0001] This specification relates to the field of coal mine safety technology, and in particular to a gas extraction drilling gas, water, and slag separation system. Background Art

[0002] Among underground drilling methods, coal seam extraction drilling can locally depressurize the surrounding coal seams. Extracting gas from the coal seams can significantly reduce gas pressure and gas content in seams with outburst hazards, while simultaneously releasing the gas potential within the coal mass. During gas extraction drilling, abnormalities such as blowouts and collapses often occur due to the influence of the coal seam, structure, ground stress, and gas pressure. The instantaneous ejection of a mixture of gas, water, and slag can bury the drill rig, injure personnel, and, in severe cases, cause accidents such as gas exceeding the limit.

[0003] Therefore, it is hoped to propose a gas, water and slag separation system for gas extraction drilling to reduce the harm caused by the instantaneous gas outburst when the spray hole collapses in the hole, and to improve the safety and reliability of gas extraction drilling.

[0012] To more clearly illustrate the technical solutions of the embodiments of this specification, the following briefly describes the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this specification. Those skilled in the art can apply this specification to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

However, if other terms can achieve the same purpose, the terms may be replaced by other expressions.

[0014] As used in this specification and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not refer to the singular but also include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

It should be understood that preceding or following operations do not necessarily need to be performed in exact order. Instead, the steps may be processed in reverse order or simultaneously. Furthermore, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0016] During underground drilling in coal mines, pre-draining gas is necessary to reduce the gas content in coal seams. However, due to the influence of the coal seam, structure, ground stress, and gas pressure, abnormal phenomena such as blowout and collapse often occur during this process. The instantaneous ejection of a mixture of coal and gas can bury the drill rig and injure personnel.

[0021] In some embodiments of this specification, an electric robotic arm is used to fix the orifice collecting device 1 to achieve the effect of fixing the pipeline and preventing the hole from collapsing. By designing the orifice collecting device 1 into an inner and outer tube, the harm of the spray hole is reduced, and the interactive terminal 4 and the processor 5 are used to interact, control and adjust the production parameters, and finally the separation of gas, water, slag and coal is achieved.

[0022] Figure 2A 1 is a schematic diagram illustrating the connection of some devices in a gas extraction drilling gas, water, and slag separation system 100 according to some embodiments of this specification.

[0027] A drill pipe is a threaded steel pipe used for drilling. The drill pipe is installed in a borehole collection device 1 and is used to perform gas extraction drilling under the control of a drilling rig. Gas extraction drilling involves drilling and gas extraction using the drill pipe and a gas, water, and slag separation system 100.

[0028] The material to be processed refers to the mixture extracted by the gas extraction drilling gas, water, and slag separation system and needs to be treated. The material to be processed may include at least one of slag, coal, gas, and water.

[0031] When the gas extraction drilling gas, water, and slag separation system 100 is in operation, the processor 5 controls the drill pipe to perform gas extraction drilling. The orifice collection device 1 collects a large amount of unprocessed material generated during the drilling process into the collection chamber 13. The gas in the unprocessed material, mixed with some small particles of slag, coal, etc., is transported through the first exhaust port 1322 via the corresponding pipeline to the intelligent slag collection and filtering device 2. The gas entering the intelligent slag collection and filtering device 2 is collected by the gas collection device 24. The large particles of slag, coal, and water in the unprocessed material are transported through the first slag discharge port 1321 to the intelligent slag-water separation device 3. After filtering the liquid substances such as water in the unprocessed material, the intelligent slag-water separation device 3 transports the solid substances such as slag and coal in the unprocessed material to the centralized slag processing location via the conveying device.

[0032] The intelligent slag collection and filtering device 2 refers to a device for performing slag collection and filtering treatment on the untreated material collected by the orifice collection device 1.

For more information about the air inlet 218, please refer to Figure 4 and related instructions.

[0033] Slag collection and filtration refers to the process of collecting and filtering the material to be processed. For example, the intelligent slag collection and filtration device 2 performs slag collection and filtration on the material to be processed collected by the orifice collection device 1. Another example is the intelligent slag collection and filtration device 2 extracting and processing gas entering the intelligent slag-water separation device 3.

For example, the slag collecting box 21 can collect the material to be processed from the orifice collecting device 1. For another example, the slag collecting box 21 can collect the material to be processed from the intelligent slag-water separation device 3.

[0036] In some embodiments, the bottom of the slag collecting box 21 may be designed to be arc-shaped so that the slag entering the slag collecting box 21 can be flushed out from the bottom of the slag collecting box 21 by high-pressure water.

[0037] In some embodiments, the slag collecting box 21 can be made of a 5 mm thick steel plate. In some embodiments, the size of the slag collecting box 21 can be determined according to the specific usage scenario.

[0038] The image acquisition device 22 refers to a device for acquiring images of the slag collecting box 21. For example, the image acquisition device 22 can acquire internal image data of the slag collecting box 21 so that the user can obtain relevant usage conditions of the interior of the slag collecting box 21. The image acquisition device 22 can be a device with a shooting or recording function, for example, the image acquisition device 22 can be a camera, etc. For more information, see Figure 4 .

[0039] The flushing device 23 is a device for flushing water into the slag collecting box 21. For example, the flushing device 23 can be a high-pressure water gun. In some embodiments, the number of flushing devices 23 can correspond to the number of flushing ports, with one flushing device 23 corresponding to one flushing port, that is, each flushing port can flush the slag collecting box 21 based on different water pressures. The water pressure of the flushing port is positively correlated with the flushing power of the flushing device 23. For more information on flushing power, see Figure 4 and Figure 5 content.

[0040] The gas collection device 24 is a device for collecting gas, such as a gas collecting box, gas collecting bottle, or gas collecting tank. The gas collection device 24 may include an air pump for extracting gas. The gas collection device 24 can be connected to the intelligent slag collection and filtering device 2 to collect gas entering the intelligent slag collection and filtering device 2.

[0041] The sprayer 25 is a machine used to spray dust. The sprayer 25 can be installed inside the slag collection box 21, for example, at the center of the bottom of the slag collection box 21. The sprayer 25 can have a spray nozzle. When drilling through the coal seam, coal dust may gush out. Opening the ball valve of the spray nozzle can suppress dust inside the slag collection box 21, preventing dust from gushing out of the slag collection box 21 and protecting the construction site environment.

[0042] When the gas extraction drilling gas, water, and slag separation system 100 is in operation, the intelligent slag collection and filtering device 2 can collect gas, small particles of coal slag, and the like from the material to be processed from the orifice collection device 1 through the blowout prevention and drainage port 215, filter the gas, and then collect it in the gas collection device 24. The intelligent slag collection and filtering device 2 can also collect gas from the intelligent slag-water separation device 3 through the air inlet 218 for centralized collection after filtration.

The structure is sturdy and durable, and the screen mesh gap is 0.2 mm. The sieve plate can be installed in the slag-water separation box 33 using various installation methods, such as inlay, bolt connection, bead connection, and screen hook connection.

[0048] Vibration motor refers to the motor used to vibrate the screen plate.

[0049] In some embodiments, two 0.75 kW explosion-proof vibration motors can be used. The two motors rotate in opposite directions and self-synchronously, causing the screen plate to perform periodic reciprocating motion in a linear direction, thereby achieving the purpose of graded dehydration. The vibration motors can be installed in the slag-water separation box 33 in either a vertical or horizontal installation.

[0050] The screen plate angle adjustment device refers to a device for adjusting the screen plate angle.

[0051] In some embodiments, the screen plate angle adjustment device may further include lower anchoring cylinders. For example, the screen plate angle adjustment device may include four lower anchoring cylinders, which may be disposed at four corners of the screen plate and connected to the screen plate base. The screen plate angle may be controlled based on the extension and contraction of the four lower anchoring cylinders.

[0052] In some embodiments, the screen plate angle can also be centrally controlled by the drilling rig's hydraulic system. For example, four lower anchor cylinders can be connected to the drilling rig's hydraulic system via two oil distributors, and the screen plate angle can be adjusted based on the user's control of the extension and retraction of the four lower anchor cylinders in the drilling rig's hydraulic system.

[0053] The conveying device refers to a device for conveying the objects to be processed. For example, the conveying device can be a conveyor belt, etc. The conveying device can be installed under the sieve plate to transport the objects rolling off the sieve plate.

[0067] In some embodiments of this specification, an electric manipulator 13 is used to fix the oil cylinder, and the oil cylinder is used to press the collecting chamber 13 against the orifice, so as to achieve the effect of fixing the pipeline and preventing the hole from collapsing. By designing the collecting chamber 13 into an inner and outer tube, the harm of the spray hole is reduced. The interactive terminal 4 and the processor 5 are used to control and adjust the production parameters to achieve the separation of gas, water, slag and coal.

[0068] Figure 3 is an exemplary schematic diagram of an orifice collection device according to some embodiments of the present specification.

[0069] like Figure 3 As shown, in some embodiments, the collecting chamber 13 is a double-layer structure, including an inner tube 131 and an outer tube 132 .

[0070] The inner tube 131 refers to the portion of the collecting chamber 13 for mounting the drill rod. For example, the inner tube 131 may be a tubular structure with a diameter of 10 cm, 15 cm, or the like.

[0071] In some embodiments, a rubber gasket seal is provided on the end face of the inner tube to prevent fine coal powder from being ejected from the drill rod passage of the inner tube 131 during drilling.

[0072] Outer tube 132 is the portion of collection chamber 13 used to collect and transport the waste to be processed. For example, outer tube 132 may be a tubular structure with a diameter of 20 cm, 30 cm, or 40 cm. The diameter of outer tube 132 may be larger than that of inner tube 131 to increase the space in collection chamber 13 and mitigate the risk of the spray holes.

[0073] In some embodiments, the outer tube 132 includes a first slag discharge port 1321 and a first exhaust port 1322 ; the intelligent slag-water separation device 3 is connected to the first slag discharge port 1321 through a pipeline; and the intelligent slag collection and filtering device 2 is connected to the first exhaust port 1322 through a pipeline.

[0074] The first slag discharge port 1321 is a port in the outer tube 132 for conveying slag, coal, and water from the material to be processed. For example, the orifice collection device 1 can convey slag, coal, and water from the material to be processed to the intelligent slag-water separation device 3 through the first slag discharge port 1321 .

[0075] In some embodiments, the first slag discharge port 1321 forms an angle of 30 degrees with the drill rod insertion port, so that the untreated material returned from the hole flows out in a parabolic direction.

[0076] The first exhaust port 1322 is a port in the outer tube 132 for conveying gas in the object to be processed. For example, the orifice collection device 1 can convey gas in the object to be processed to the intelligent slag collection and filtering device 2 through the first exhaust port 1322 .

[0077] In some embodiments, when the air pressure in the borehole meets a preset condition, the first exhaust port 1322 can be opened automatically. The first exhaust port 1322 can also be opened manually.

[0078] In some embodiments, a filter and a water barrier are provided within the first exhaust port 1322. The filter prevents large particles of solid waste to be processed from being drawn into the extraction pipeline during drilling, thus providing a drainage and filtration function. The water barrier prevents liquids such as water from entering the extraction pipeline. A long cutout is provided below the water barrier to ensure that waste and water to be processed fall into the first slag discharge port 1321.

[0079] In some embodiments, the collection chamber further includes an air pressure sensor 133, which is used to monitor changes in air pressure in the borehole; the air pressure sensor 133 is communicatively connected to the processor.

[0080] The air pressure variation in the borehole refers to the degree to which the air pressure in the borehole changes per unit time when the drill pipe is operating. For example, the air pressure variation in the borehole can be 5 kPa / min, 10 kPa / min, etc. The air pressure variation in the borehole can be monitored by an air pressure sensor 133 installed in the borehole.

[0081] In some embodiments, when the air pressure sensor 133 detects that the air pressure change in the borehole meets the preset conditions, it sends a notification to the processor, and the processor issues a control instruction to control the working parameters of the gas collection device. The control instruction includes turning on the gas collection device or increasing the extraction power.

[0082] The preset condition refers to the air pressure variation in the borehole reaching a specified range. For example, the preset condition may include the air pressure variation in the borehole being greater than 5kPa / min, the air pressure variation in the borehole being greater than 10kPa / min, etc. The preset condition can be set manually.

[0083] When the air pressure change in the borehole meets the preset conditions (for example, greater than the preset value), the processor 5 can issue control instructions to control the working parameters of the gas collection device, such as turning on the gas collection device, increasing the pumping power, etc., to alleviate the blowout phenomenon caused by excessive pressure.

[0084] The operating parameters of the gas collection device refer to relevant operating parameters of the gas collection device when it is in operation. For example, the operating parameters of the gas collection device may include the extraction power of the gas collection device.

[0085] In some embodiments of this specification, an air pressure sensor 133 is set in the borehole to monitor the air pressure changes, so that excessive pressure during gas extraction drilling can be detected in time, and decompression measures can be taken in time to alleviate the blowout phenomenon caused by excessive pressure.

[0086] In some embodiments, the electric robotic arm includes at least three supports and a hydraulic cylinder.

[0087] The support refers to the electric manipulator structure used for supporting. The connection method between the support and the electric manipulator 12 can be welding, riveting, etc.

[0088] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, performing linear reciprocating motion (or oscillating motion). The hydraulic cylinder can be used to abut the collection chamber 13 against the rock wall. The hydraulic cylinder can be connected to the drilling rig's hydraulic system and controlled by the user through the interactive terminal 4.

[0089] In some embodiments, the orifice collection device further includes a water spray gun 14; the water spray gun 14 is used to assist the drill pipe in hydraulically removing slag during drilling.

[0090] The water spray gun 14 refers to a device for spraying water. For example, the water spray gun 14 can be a high-pressure water gun, etc. There can be multiple water spray guns 14, which can be controlled by the processor 5.

[0091] Slag discharge refers to the discharge of slag, water, etc. from the object to be processed. For example, the orifice collection device 1 can discharge slag, water, etc. from the object to be processed into the intelligent slag-water separation device 3 through the first slag discharge port 1321 .

[0092] In some embodiments, the water spraying power of the water spray gun 14 is related to the drilling rate, hole diameter, and soil type.

[0093] The water spraying power of the water spray gun 14 refers to the power of the water spray gun 14 when it is in operation. The water spraying power of the water spray gun 14 can be adjusted according to the drilling rate, hole diameter, soil type, etc. For example, the higher the drilling rate and the larger the hole diameter, the higher the water spraying power of the water spray gun 14.

[0094] The drilling rate can be characterized by the drill pipe's rotational speed. The hole diameter refers to the diameter of the drill hole. The soil type refers to the classification of soil based on its characteristics. For example, soil types can include high-hardness soil and low-hardness soil.

[0095] In some embodiments, the processor 5 can determine the water spray power of the water spray gun 14 based on historical data. For example, the processor 5 can construct a reference feature vector corresponding to each drilling scenario based on drilling feature information from multiple historical drilling scenarios. The drilling feature information includes drilling rate, hole diameter, and soil type.

[0096] The reference feature vector is a vector constructed based on the drilling characteristic information of the water jet gun 14 at various water jet powers. There are various ways to construct a reference feature vector based on drilling characteristic information. For example, a feature vector p is constructed based on the drilling characteristics (x, y, z) of the corresponding environment. The drilling characteristics (x, y, z) may represent a drilling rate of x, a hole diameter of y, and a soil type of z for the corresponding borehole.

[0097] The database may include multiple reference feature vectors, and each of the multiple reference feature vectors may have a corresponding reference water spraying power.

[0098] In some embodiments, the processor 5 may construct a to-be-matched vector based on the drilling feature information in the current drilling scene. The construction method of the to-be-matched vector is similar to the construction method of the reference feature vector described above.

[0099] In some embodiments, the processor 5 can calculate the distance between the reference vector and the vector to be matched, determine the target vector, and then determine the water spray power of the water spray gun 14 based on the water spray power corresponding to the target vector. For example, the processor 5 can use a reference feature vector whose vector distance from the vector to be matched meets a preset distance condition as the target vector, and use the reference water spray power corresponding to the target vector as the water spray power corresponding to the vector to be matched. The preset distance condition can be set according to the circumstances. For example, the preset drilling condition can include a minimum vector distance or a vector distance less than a distance threshold, and the vector distance can include a cosine distance, etc.

[0100] In some embodiments of this specification, the water spraying power is determined by vector matching, so that the use of the water spray gun 14 is more in line with actual needs, thereby achieving the purpose of water saving.

[0101] In some embodiments, water spraying is stopped when the processor detects that the air pressure change in the borehole meets a preset air pressure change condition. The preset air pressure change condition may include an increase / decrease in the air pressure within a unit to a preset air pressure value, or a change in the air pressure within a unit reaching a preset air pressure change value. For example, if the air pressure sensor 133 detects that the air pressure has reached normal pressure (i.e., one standard atmosphere, 101.325 kPa) within a certain period of time, the gas extraction drilling is considered to be relatively mild, and the processor 5 controls the water spray gun 14 to stop spraying water.

[0102] In some embodiments of the present specification, the air pressure change in the borehole is monitored to determine whether to spray water, so that the use of the water spray gun 14 is more in line with actual needs, thereby achieving the purpose of water saving.

[0103] In some embodiments of the present specification, an electric mechanical arm 13 is used to fix the oil cylinder, and the oil cylinder is used to press the collecting chamber 13 against the rock wall, so as to achieve the effect of fixing the pipeline and preventing the hole from collapsing. By designing the collecting chamber 13 into a double-layer structure and setting an air pressure sensor 133 in the borehole to monitor the air pressure changes, it is possible to timely detect the situation of excessive pressure during the gas extraction drilling process, and then timely take pressure reduction measures to alleviate the blowout phenomenon caused by excessive pressure.

[0104] Figure 4 It is an exemplary schematic diagram of an intelligent slag collection and filtering device according to some embodiments of this specification.

[0105] like Figure 4 The figure shows a schematic diagram of an intelligent slag collection and filtration device 2, which may include a slag collection box 21, an image acquisition device 22, a water flushing device 23, a gas collection device 24, and a sprayer 25. The slag collection box 21 is used to receive materials to be processed, the image acquisition device 22 is used to capture images of the slag collection box 21, the water flushing device 23 is used to flush the slag collection box 21, the gas collection device 24 is used to extract gas from the slag collection box 21, and the sprayer 25 is used to generate a spray within the slag collection box.

[0106] In some embodiments, the intelligent slag collection and filtering device 2 further includes a buffer cylinder 26 ; the buffer cylinder 26 is connected to the slag collection box 21 , and the buffer cylinder is used to share the pressure in the slag collection box 21 .

[0107] The buffer tube 26 is a tube that can slow down the impact of the spray hole. One end of the buffer tube 26 can be connected to the mounting port on the slag collecting box 21, and the other end of the buffer tube 26 can be controlled to open and close according to actual use.

[0108] In some embodiments, the position of the installation opening of the buffer cylinder 26 on the slag collecting box 21 can be pre-set according to user needs. Figure 4 As shown, the installation opening of the buffer tube 26 on the slag collecting box 21 can be set at the end of the slag collecting box 21. In some embodiments, the diameter of the connection port between the buffer tube 26 and the slag collecting box 21 can be greater than or equal to the diameter of the installation opening in the slag collecting box 21.

[0109] In some embodiments, the shape, material, and length of the buffer tube 26 can be pre-configured based on user needs. For example, the buffer tube 26 can be shaped like a bag (e.g., a straight bag, a pouch), a tube (e.g., a ribbed tube, a trouser-shaped tube), or the like. The buffer tube 26 can be made of a non-stretchable material (e.g., fabric) or a stretchable material (e.g., rubber, plastic). For another example, if the blasting phenomenon is mild, the length of the buffer tube 26 can be shortened, while if the blasting phenomenon is severe, the length of the buffer tube 26 can be lengthened.

[0110] In some embodiments, the mounting opening of the buffer cylinder 26 on the slag collection box 21 can also serve as a slag removal opening. This opening allows the slag collection box 21 to be opened at any time if slag is not discharged promptly, thus preventing slag accumulation. In some embodiments, the buffer cylinder 26 can also serve as a slag removal cylinder. A slag removal cylinder is a cylinder used to remove and discharge slag.

[0111] By setting a buffer cylinder 26 in the intelligent slag collection and filtering device 2 as described in some embodiments of this specification, when the blowhole is serious, the pressure released by the gas mixture sprayed out of the hole is buffered, thereby preventing the pressure in the slag collection box 21 from exceeding the specified limit and reducing the occurrence of accidents during gas extraction drilling.

[0112] In some embodiments, the slag collecting box 21 includes at least one of an image acquisition port 211, a water flushing port 212, a gas filtering and collecting port 213, a second slag discharge port 214, a blowout prevention and drainage port 215, and an air inlet 218. The number of the image acquisition port 211, the water flushing port 212, the gas filtering and collecting port 213, the second slag discharge port 214, and the blowout prevention and drainage port 215 can be one or more.

[0113] The image acquisition port 211 is a port located on the slag collecting box 21 for collecting images of the interior of the slag collecting box 21. In some embodiments, the position of the image acquisition port 211 can be pre-set according to user needs. For example, the position of the image acquisition port 211 can be the top surface, front surface, back surface, side surface, bottom surface, etc. of the slag collecting box 21. Figure 4 As shown, the image acquisition port 211 is located on the front side of the slag collecting box 21 .

[0114] Internal image data refers to image data of the interior of the slag collecting box 21 during the slag collecting and filtering process of the gas extraction drilling hole. The internal image data can reflect the slag accumulation data and the residual volume data of the slag collecting box 21.

[0115] In some embodiments, the image acquisition port 211 may be used for the image acquisition device 22 to acquire internal image data of the slag collecting box 21 .

[0116] The image acquisition device 22 may include a camera and a dust mask provided on the outside of the camera. For example, the camera of the image acquisition device 22 may be a high-definition 360° rotating camera, and the dust mask may be a spherical colorless glass cover. In some embodiments, the image acquisition device 22 may also include a light source searchlight. For example, the light source searchlight may be provided in the camera, and the light source searchlight may be used to complete image acquisition in the dim slag collection box 21, thereby ensuring the image acquisition quality. For more information about the image acquisition device 22, please refer to Figure 3 and its related descriptions.

[0117] In some embodiments, the installation position of the image acquisition device 22 can be pre-set according to user needs. For example, the installation position of the image acquisition device 22 can be close to the image acquisition port 211 so that the image acquisition device 22 can collect internal image data of the slag collecting box 21 through the image acquisition port 211. Figure 4 As shown, the image acquisition device 22 is installed on the top right side of the slag collecting box 21.

[0118] By providing the image acquisition port 211 in the slag collecting box 21 as described in some embodiments of this specification, the internal image of the slag collecting box 21 can be acquired in real time, making it convenient to observe the slag filtering condition in the slag collecting box 21 .

[0119] The flushing port 212 refers to a port located inside the slag collecting box 21 for flushing water.

[0120] In some embodiments, the position, number, material, and shape of the flush port 212 can be pre-set according to user needs. Figure 4 As shown, the flushing port 212 is located at the top edge of the slag collecting box 21. For another example, the number of the flushing port 212 can be one or more, such as Figure 4 As shown, the number of flushing ports 212 is 6. For another example, the inner pipe material of the flushing port 212 can be a galvanized welded pipe, which is convenient for shaping the port of the flushing port 212 and is not easily damaged. Figure 4 As shown, the shape of the flushing port 212 can be flat, so as to facilitate high-pressure and wide-range flushing of the slag collecting box 21 .

[0121] In some embodiments, the flushing port 212 is used to supply water to the flushing device 23. For example, the flushing port 212 can flush out the mixed slag such as slag, coal, etc. in the slag collecting box 21 based on the flushing device 23. At the same time, as mentioned above, in order to facilitate flushing and slag discharge, the bottom of the slag collecting box 21 can be designed with a certain curvature, so that the slag can be discharged from the second slag discharge port based on high pressure. For more details about the flushing device 23, please see Figure 3 and its related descriptions.

[0122] By providing a flushing port 212 in the slag collecting box 21 as described in some embodiments of this specification, the slag in the slag collecting box 21 can be cleaned in real time to avoid slag accumulation and blockage in the slag collecting box 21 .

[0123] The gas filter collection port 213 is a port located on the slag collection box 21 for filtering and collecting the gas inside the slag collection box 21. In some embodiments, the position of the gas filter collection port 213 can be pre-set according to user needs. For example, Figure 4 As shown, the gas filtering and collecting port 213 is located on the top left side of the slag collecting box 21 .

[0124] In some embodiments, a filter screen 27 may be provided inside the gas filter collection port 213. By providing the filter screen 27 inside the gas filter collection port 213, the purity of the gas filtered and collected in the slag collection box 21 can be improved, and the probability of slag clogging the gas extraction pipeline can be reduced.

[0125] In some embodiments, the gas filter collection port 213 is used to extract gas from the gas collection device 24. Figure 4 As shown, the gas collection device 24 is connected to the slag collecting box 21 through the gas filtering and collecting port 213 to extract the gas in the slag collecting box 21. For more details about the gas collection device 24, please refer to Figure 3 and its related descriptions.

[0126] By providing a gas filtering and collecting port 213 on the slag collecting box 21 as described in some embodiments of this specification, the gas in the slag collecting box 21 can be collected and filtered in real time, thereby avoiding danger caused by excessive gas in the slag collecting box 21.

[0127] The second slag discharge port 214 refers to a port located on the slag collecting box 21 for discharging the slag inside the slag collecting box 21. In some embodiments, the position of the second slag discharge port 214 can be pre-set according to user needs. For example, Figure 4 As shown, the second slag discharge port 214 can be set at a position such as the left side of the bottom or the lower right side of the side of the slag collecting box 21.

[0128] In some embodiments, the second slag discharge port 214 is used to discharge the slag and / or coal in the slag collecting box 21. In some embodiments, the second slag discharge port 214 may include a hydraulic slag discharge port, a hoe slag discharge port, a blowout prevention slag collection port, and other slag discharge ports with different functions. Figure 4 As shown, the hydraulic slag discharge port can be located at the left side of the bottom of the slag collecting box 21. The hydraulic slag discharge port can be a port for flushing the slag and / or coal in the slag collecting box 21 with water using the flushing port 212; for example, Figure 4As shown, the slag hoeing port can be located at the lower right side of the side of the slag collecting box 21, and the slag hoeing port can be a port for shoveling away the slag and / or coal in the slag collecting box 21; for example, Figure 4 As shown, the blowout prevention and slag discharge collection port can be located in the middle of the right side of the slag collection box 21. The blowout prevention and slag discharge collection port can be a port for preventing the ejection of slag and / or coal from the slag collection box 21 and for discharging the slag and / or coal from the slag collection box 21. In some embodiments, the blowout prevention and slag discharge collection port can be connected to the gas outlet of the intelligent slag-water separation device 3 via a pipeline to extract the gas in the intelligent slag-water separation device 3.

[0129] As described in some embodiments of this specification, by setting a second slag discharge port 214 on the slag collecting box 21, the slag accumulated in the slag collecting box 21 can be easily discharged to avoid blockage of the discharge port due to excessive slag in the slag collecting box 21. At the same time, it can also serve as a connection port with the intelligent slag-water separation device 3 to collect and filter the gas in the intelligent slag-water separation device 3.

[0130] The blowout prevention discharge port 215 refers to a discharge port located on the slag collecting box 21 for preventing blowout holes.

[0131] In some embodiments, the orifice collection device 1 is connected to the intelligent slag collection and filtration device 2 via a blowout prevention and drainage port 215. For example, when the intelligent slag collection and filtration device 2 is in use, the blowout prevention and drainage port 215 of the intelligent slag collection and filtration device 2 can be connected to the first exhaust port of the orifice collection device, and the gas filtration and collection port 213 of the intelligent slag collection and filtration device 2 can then be connected to the underground gas drainage pipeline. When the borehole approaches a coal mine, the gate valve of the filter port is quickly opened. Using the negative drainage pressure, the gas mixture ejected from the borehole is drawn into the intelligent slag collection and filtration device 2. After being filtered by the filter screen 27 on the gas filtration and collection port 213 of the intelligent slag collection and filtration device 2, the gas is drawn into the drainage pipeline, leaving the slag in the slag collection box 21. When the slag accumulates to a certain level, the flushing port 212 is opened. Multiple flushing ports 212 simultaneously flush water downward along the inner edge of the slag collection box 21, discharging the slag in the slag collection box 21 through the lower second slag discharge port 214 (e.g., a hydraulic slag discharge port).

[0132] By connecting the blowout prevention extraction port 215 provided on the slag collecting box 21 to the first exhaust port of the smart hole collection device 1 as described in some embodiments of this specification, and opening it when uncovering coal during the drilling process, a large amount of gas that may gush out of the blowout hole can be extracted in time, effectively preventing the occurrence of gas over-limit accidents.

[0133] In some embodiments, the slag collecting box 21 further includes at least one gravity sensor 216 , and the gravity sensor 216 is communicatively connected to the processor.

[0134] The gravity sensor 216 is a sensor that converts gravity into an electrical signal. For example, the gravity sensor 216 can be a strain gauge sensor, a piezoresistive gravity sensor, or the like.

[0135] In some embodiments, the gravity sensors 216 may be regularly distributed at the bottom of the slag collecting box 21. For example, assuming that five gravity sensors are provided at the bottom of the slag collecting box 21, gravity sensor A may be provided at the bottom middle position of the slag collecting box 21 to monitor the total gravity within the slag collecting box 21, and the remaining gravity sensors (e.g., gravity sensor B, gravity sensor C, gravity sensor D, and gravity sensor E) may be respectively distributed at the four corners of the bottom of the slag collecting box 21 to monitor the gravity at the four corners within the slag collecting box 21.

[0136] In some embodiments, the position of the flushing port 212 may be related to the position of the gravity sensor 216. For example, if gravity sensors B, C, D, and E are respectively located at the four corners of the bottom of the slag collecting box 21, the flushing port 212 may be set at the four corners of the top of the slag collecting box 21, or the flushing directions of multiple flushing ports 212 may be aligned at different positions on the bottom of the slag collecting box 21.

[0137] In some embodiments, the gravity sensor 216 is used to monitor gravity change data at different locations in the slag collecting box 21 .

[0138] The gravity change data includes the gravity change rate and the maximum gravity value.

[0139] The gravity change rate refers to the degree of change of the slag weight in the slag collecting box 21 per unit time.

[0140] In some embodiments, the rate of change of gravity can be determined based on the weight of the slag in the slag collecting box 21 at different times. For example, if the weight of the slag in the slag collecting box 21 at time T1 is 10 kg and the weight of the slag at time T2 is 40 kg, then the rate of change of gravity in the slag collecting box 21 is (40 kg - 10 kg) / (T2 - T1).

[0141] The maximum gravity value refers to the maximum weight value reached by the slag in the slag collecting box 21 detected by the gravity sensor 216. For example, the gravity sensor 216 detects that the maximum gravity value of the slag in the slag collecting box 21 is currently 1000 kg.

[0142] In some embodiments, the maximum gravity value can be determined based on the gravity values at the locations corresponding to the respective gravity sensors. For example, if the gravity value at the location corresponding to gravity sensor B is 500 kg, the gravity value at the location corresponding to gravity sensor C is 400 kg, the gravity value at the location corresponding to gravity sensor D is 300 kg, and the gravity value at the location corresponding to gravity sensor E is 200 kg, then the maximum gravity value can be the gravity value at the location corresponding to gravity sensor B, which is 500 kg.

[0143] In some embodiments, when the gravity change data meets a preset gravity condition, the processor may issue a control instruction to control the flushing device 23 to perform a flushing operation from at least one flushing port 212 into the slag collecting box.

[0144] The preset gravity condition refers to a pre-set condition that the gravity change data must meet when flushing the slag collection box. For example, the preset gravity condition may be that the gravity change rate exceeds a preset change rate threshold and / or the maximum gravity exceeds a gravity threshold. For example, the preset gravity condition may be that the maximum weight of the slag in the slag collection box 21 exceeds 100 kg, or the gravity change rate of the slag in the slag collection box 21 exceeds 100 kg / h.

[0145] In some embodiments, in response to the gravity change data satisfying a preset condition, the processor issues an instruction to control the flushing device 23 to flush water into the slag collection box through at least one flushing port 212. For example, when the slag in the slag collection box 21 accumulates to a certain weight (e.g., 100 kg), the flushing device 23 is controlled to flush water downward along the interior of the slag collection box 21 through the flushing port 212, discharging the slag in the slag collection box 21 through the second slag discharge port 214 (e.g., a hydraulic slag discharge port) at the bottom.

[0146] In some embodiments, the weight of slag at different positions in the slag collecting box 21 is different, and the number, position, and power of the corresponding flushing ports 212 are also different.

[0147] In some embodiments, the processor may process the gravity change data using a flushing model to determine the number and positions of the flush openings and the flushing power.

[0148] The flush model can be used to determine the number and location of flush ports 212 opened, as well as the flush power. In some embodiments, the flush model can be a machine learning model. In some embodiments, the flush model can be a neural network model, including various feasible models, such as convolutional neural networks (CNNs), deep neural networks (DNNs), or combinations thereof.

[0149] In some embodiments, the input of the flush model may be gravity change data, and the output of the flush model may be the number and location of flush outlets 212 opened, as well as the flushing power. The output of the flush model can be represented by a sequence. For example, the output of the flush model can be represented by Y = {(A1, B1), (A2, B2), …, (An, Bn)}, where (An, Bn) represents the operating status of flush outlet n, such as whether it is open or closed (not open). For example, An can take the value of 1 or 0, corresponding to whether flush outlet n is open or closed (not open). Bn takes the value of the flushing power when flush outlet n is open. If An is 0 (i.e., flush outlet n is closed), then Bn is also 0.

[0150] The numbers of the flushing ports can be preset, for example, Figure 4 As shown, there are 5 flushing ports 212, which are numbered 1 to 5 from left to right. Flushing ports with different numbers can be used to flush different positions of the slag collecting box 21.

[0151] The number of flush ports 212 opened refers to the number of flush ports 212 used during operation, and can be determined based on the number of flush ports whose Ai (0<i<n) value is 1 in the output of the flush model.

[0152] The open position of the flush port 212 refers to the position of the flush port 212 used during operation, and is related to the installation position of the open flush port 212. In some embodiments, when the intelligent slag collection and filtering device 2 is in operation, assuming that there is a large amount of slag on the left side of the slag collection box 21, the open position of the flush port 212 can be the flush ports numbered 1-3, etc.

[0153] The flushing power can indicate the speed of the flushing. For example, a greater flushing power means a greater water flow through the flushing port 212, that is, a greater water pressure; a smaller flushing power means a smaller water flow through the flushing port 212, that is, a smaller water pressure.

[0154] In some embodiments, the flushing power of the flushing port 212 can be obtained through a flushing model based on the slag gravity change data in the slag collecting box 21 .

[0155] In some embodiments, the flushing model can be trained independently based on historical data. In some embodiments, the flushing model can be trained using multiple labeled training samples. For example, multiple labeled training samples can be input into an initial flushing model. A loss function is constructed using the labels and the results of the initial flushing model, and the parameters of the flushing model are iteratively updated based on the loss function. Model training is completed when the loss function of the initial flushing model meets preset conditions, resulting in a trained flushing model. The preset conditions may include convergence of the loss function or a threshold number of iterations.

[0156] In some embodiments, training samples may include sample gravity change data. Labels may be the operating status of the sample flush outlet 212. In some embodiments, training samples may be obtained based on historical data (e.g., historical gravity change data), and labels may be obtained through manual or automatic labeling. Training sample labels may also be obtained through various methods, without limitation herein.

[0157] In some embodiments, the flush model can be used to predict the number and location of flush ports 212 opened and the flush power corresponding to the updated gravity change data. For example, based on the updated gravity change rate after a flush, the flush model can be re-analyzed and predicted to determine whether to adjust the number and location of flush ports 212 opened and the flush power.

[0158] In some embodiments of the present specification, gravity change data is processed by a flushing model to determine the number and position of the flushing ports 212 opened and the flushing power, which can improve the accuracy of predicting the opening of the flushing ports 212, thereby avoiding the blockage of slag in the slag collecting box 21 and avoiding blindly increasing water pressure, saving resources.

[0159] In some embodiments, the intelligent slag collection and filtering device 2 further includes a slidable support device 217 .

[0160] The slidable support device 217 is a device that can slide on the ground and support the slag collecting box 21. The slidable support device 217 can be located at the bottom of the slag collecting box 21. The shape of the slidable support device 217 can be a long strip. For example, Figure 4 As shown, the slidable support device 217 can be a long smooth strip with tilted sides, for example, the slidable support device 217 can be a sled leg.

[0161] In some embodiments of the present specification, the slidable support device 217 can not only support the intelligent slag collection and filtering device 2, but also be conveniently and simply moved according to actual conditions, thereby reducing manpower.

[0162] In some embodiments, the intelligent slag collection and filtering device 2 further includes a sprayer 25, which is used to generate spray in the slag collection box. Figure 3 and its related descriptions.

[0163] In some embodiments of the present specification, the structural design of the image acquisition port, flushing port, gas filtration collection port, second slag discharge port and blowout prevention and extraction port of the slag collection box 21 can not only improve the slag collection and filtration efficiency, but also significantly improve the environmental sanitation of the construction site and improve the safety and reliability of gas extraction drilling.

[0164] In some embodiments, the effect of separating the slag-water mixture on the sieve plate is related to the inclination angle of the sieve plate of the slag-water separation device.

[0165] In some embodiments, the screen plate angle adjustment device is communicatively connected to the processor, and the processor obtains the ground inclination angle, determines the screen plate angle adjustment data and sends an adjustment instruction to the screen plate angle adjustment device to adjust the inclination angle of the screen plate.

[0166] The ground tilt angle refers to the angle at which the ground is tilted relative to the horizontal plane. For example, in an uneven underground surface or inclined tunnel, the ground tilt angle may be 30° upward from the southeast. In some embodiments, the ground tilt angle can be obtained by a processor. For example, the screen plate angle adjustment device can utilize a gyroscope, an accelerometer, or a magnetometer to obtain the ground tilt angle through the processor.

[0167] The screen plate angle adjustment data refers to the angle data of the screen plate that needs to be changed. For example, the screen plate angle adjustment data can be expressed in the form of coordinates. For example, a spatial coordinate system is established with the center point of the screen plate as the origin, wherein the screen plate angle adjustment data can be expressed by coordinates P (X, Y, Z), where X, Y, and Z can respectively represent the screen plate angle adjustment parameters in different directions.

[0168] In some embodiments, the screen plate angle adjustment data can be manually determined. In some embodiments, a table comparing ground tilt angles and screen plate angle adjustment data can be preset, and the screen plate angle adjustment data can be determined by looking up the table based on the ground tilt angle. For example, the screen plate angle adjustment data corresponding to the ground tilt angle can be specified, and a table comparing the screen plate angle adjustment data can be obtained, and the screen plate angle adjustment data can be determined by looking up the table based on the current ground tilt angle.

[0169] In some embodiments, the screen plate angle adjustment data can be determined by an angle model. For example, based on historical ground tilt angle data and historical screen plate angle adjustment data, the current screen plate angle adjustment data is determined by the angle model based on the current ground tilt angle data.

[0170] The adjustment instruction refers to an instruction that can control the adjustment of the screen plate angle. In some embodiments, the processor can send the adjustment instruction to the screen plate angle adjustment device.

[0171] The screen plate inclination angle refers to the angle at which the screen plate is tilted relative to the horizontal plane. For example, the screen plate inclination angle can be 30° downward in the southeast direction. In some embodiments, the screen plate inclination angle can be determined by a processor. For example, the screen plate angle adjustment device can determine the screen plate inclination angle through the processor based on the adjustment instruction.

[0172] In some embodiments, the sieving time of the object to be processed on the sieve plate can be determined based on the characteristic data of the object to be processed, and the inclination angle of the sieve plate can be determined based on the sieving time.

[0173] Characteristic data refers to data that can represent the relevant characteristics of the object to be processed. Figure 5 As shown, the characteristic data of the object to be processed include the content ratio 510 of slag, coal and water, the particle size 520 of slag and coal, and the amount 530 of the object to be processed collected by the intelligent slag-water separation device 3 per unit time.

[0174] In some embodiments, characteristic data of the object to be processed can be obtained based on the intelligent slag-water separation device 3. For example, a detection device can be installed on the slag-water separation box of the intelligent slag-water separation device 3. The detection device can include an image detection device for detecting image data of the object to be processed, and using the image data, obtain the content ratio 510 of slag, coal, and water, and the particle size 520 of slag and coal; the detection device can include a weight detection device for detecting weight data of the object to be processed, and using the weight data, obtain data on the amount 530 of the object to be processed collected by the intelligent slag-water separation device 3 per unit time.

[0175] In some embodiments, the characteristic data can be expressed as (x, y, z), representing the ratio of slag, coal, and water as x, the particle size grade of the slag and coal as y, and the amount of unprocessed material collected by the intelligent slag-water separation device 3 per unit time as z. The particle size grade of the slag and coal can be determined based on the average diameter of the slag and coal particles, with larger diameters indicating larger grade values.

[0176] The sieving time refers to the time it takes for the material to be processed to be filtered through the sieve plate. For example, when the ratio of slag and coal to water is high, the sieving time is longer. When the intelligent slag-water separation device 3 collects a large amount of material to be processed per unit time, the sieving time is shorter.

[0177] In some embodiments, the inclination angle of the sieve plate can be determined based on the time the material to be processed passes through the sieve plate. For example, the shorter the time the material to be processed passes through the sieve plate, the steeper the inclination angle of the sieve plate is determined to be (the steeper the inclination angle of the sieve plate, the easier it is for the material to pass through the sieve and roll onto the conveyor device of the intelligent slag-water separation device 3). For example, if the material to be processed passes through the sieve plate for 5 hours, the inclination angle of the sieve plate is determined to be 10°; if the material to be processed passes through the sieve plate for 2 hours, the inclination angle of the sieve plate is determined to be 30°.

[0178] In some embodiments, the screening time 550 can be predicted by the screening model 540 based on the characteristic data of the object to be processed.

[0179] Figure 5 is an exemplary schematic diagram of a sieving model 540 according to some embodiments of the present specification.

[0180] Screening model 540 can be used to determine screening time 550. In some embodiments, screening model 540 can be a machine learning model. In some embodiments, screening model 540 can be a variety of feasible neural network models, such as convolutional neural networks (CNNs), deep neural networks (DNNs), or combinations thereof.

[0181] In some embodiments, the input of the screening model 540 may be characteristic data of the material to be processed, and the output of the screening model 540 may be the screening time 550 of the material to be processed on the sieve plate. For example, the input of the screening model 540 may be the ratio of the content of slag, coal, and water (e.g., the content ratio of slag, coal, and water is 1:1:1), the particle size of the slag and coal (e.g., the particle size grade of the slag and coal is level 3), and the amount of material to be processed collected by the intelligent slag-water separation device 3 per unit time (e.g., the amount of material to be processed collected by the intelligent slag-water separation device 3 per hour is 100 kg). The output of the screening model 540 may be the screening time 550 (e.g., the screening time is 2 hours).

[0182] In some embodiments, screening model 540 can be trained independently based on historical data. In some embodiments, screening model 540 can be trained using multiple labeled training samples. For example, multiple labeled training samples can be input into an initial screening model, and a loss function can be constructed using the labels and the results of the initial screening model. The parameters of screening model 540 can be iteratively updated based on the loss function. When the loss function of the initial screening model meets preset conditions, model training is completed, resulting in a trained screening model 540. The preset conditions may include convergence of the loss function, a threshold number of iterations, and the like.

[0183] In some embodiments, training samples may include characteristic data of the sample to be processed. Labels may include the time the sample was screened. In some embodiments, training samples may be obtained based on historical data (e.g., characteristic data of historical processed objects), and labels may be obtained through manual labeling or automatically determined. Labels for training samples may also be obtained through various methods, which are not limited here.

[0184] In some embodiments of the present specification, the screening time of the object to be processed on the sieve plate is determined by processing characteristic data of the object to be processed through a screening model, which can improve the accuracy of screening time prediction and save energy and water.

[0185] In some embodiments of this specification, the ground inclination angle is obtained, the screen plate angle adjustment data is determined, and an adjustment instruction is sent to adjust the inclination angle of the screen plate. The inclination angle of the screen plate can be adjusted according to different ground conditions, effectively improving the separation effect of the intelligent slag-water separation device.
