Description

Technical Field This utility model relates to the technical field of coal mine gas extraction equipment, and more specifically, to a visual integrated device for slag discharge and water release. Background Technology During coal mine gas extraction, the extraction pipelines often carry a large amount of coal slag, silt, and water. If these impurities are not separated and discharged in time, they can easily accumulate in low-lying areas of the pipeline, causing blockages, increasing extraction resistance, and even damaging critical equipment such as extraction pump stations.

[0001] Currently, existing technologies typically involve installing slag removal devices and automatic water dischargers on pipelines for slag removal. However, conventional slag removal devices mostly rely on metal filter screens for interception and filtration. In the harsh working conditions of high humidity and high dust underground, the filter screens are easily clogged by coal slime, causing airflow obstruction. This requires frequent disassembly and cleaning by workers, resulting in extremely high maintenance costs.

[0002] Furthermore, existing slag removal and water discharge equipment mostly adopts a fully enclosed metal box structure, lacking effective visual monitoring methods. Staff cannot intuitively grasp the real-time slag and water accumulation levels inside the equipment, often relying solely on experience for blind slag removal or maintenance. This not only leads to low maintenance efficiency but also easily causes safety hazards such as water backflow into main pipelines due to delayed fault detection. Utility Model Content The purpose of this utility model is to provide a visual integrated slag discharge and water discharge device, which aims to solve the technical problems in the existing technology, such as the dispersed functions of slag discharge and water discharge equipment in coal mine gas extraction pipelines, inconvenient installation and maintenance, the fact that traditional slag discharge devices mostly use filter screens which are prone to clogging and require frequent cleaning, and the low efficiency of blind box operation and maintenance due to the lack of visual monitoring methods.

[0003] This utility model is achieved through the following technical solution: A visual integrated sludge and water discharge device includes: The box body is internally divided into a slag discharge chamber and a water discharge chamber, and a communication component is provided between the slag discharge chamber and the water discharge chamber; An air inlet is located on the side of the housing corresponding to the slag discharge chamber and is used to connect to a gas extraction pipeline. An exhaust port is located at the top of the housing for discharging the separated gas. A gas-solid-liquid separation mechanism is provided in the slag discharge chamber, including an inclined baffle that is positioned facing the airflow direction of the air inlet. An automatic water discharge mechanism is installed inside the water discharge chamber to control the discharge of accumulated water according to the water level; A slag discharge port assembly is disposed at the lower part of the slag discharge chamber and communicates with the slag discharge chamber; An observation component is installed on the side wall of the container to observe the accumulation of sludge or water inside the container.

[0004] The integrated visual slag discharge and water discharge device described above is characterized in that the inclined baffle is an arc-shaped plate structure, with its top end fixed to the upper inner wall of the slag discharge chamber and its bottom end extending into the slag discharge chamber and inclined.

[0005] The integrated visual slag discharge and water discharge device described above is characterized in that the inclined baffle is disposed on the airflow ejection path of the air inlet, and its plate surface blocks the front of the air inlet (2); the bottom end of the inclined baffle extends downward in a direction away from the air inlet, and the angle between the plane where the top and bottom ends of the inclined baffle are located and the vertical plane is 20° to 45°.

[0006] The integrated visual slag discharge and water dispensing device described above is characterized in that the angle between the plane containing the line connecting the top and bottom ends of the inclined baffle and the vertical plane is 23°.

[0007] In the visual integrated slag discharge and water discharge device described above, the connecting component is an overflow pipe or flow channel disposed between the slag discharge chamber and the water discharge chamber.

[0008] In the visual integrated slag discharge and water discharge device described above, the height of the water inlet of the connecting component is lower than the height of the air inlet, but higher than the height of the slag discharge port component.

[0009] As described above, the integrated visual slag discharge and water discharge device includes a water inlet for connecting the slag discharge chamber and the water discharge chamber. The automatic water discharge mechanism includes: A one-way valve for water inlet is located inside the water outlet chamber and is disposed on one side of the water inlet connection port; The valve stem is vertically installed inside the drain chamber; A float ball is mounted on the valve stem; A valve body assembly is disposed on the top wall of the housing corresponding to the drain chamber; the valve body assembly includes a negative pressure interface for communicating with a negative pressure environment, and an atmospheric communication assembly disposed next to the negative pressure interface, the atmospheric communication assembly including a vent pipe communicating with the atmosphere and a sealing cap covering the vent pipe; An opening and closing element is installed on the upper part of the valve stem. The opening and closing element includes a negative pressure seal for blocking the negative pressure interface and a push rod for pushing the sealing cap. A drain outlet is provided at the bottom of the drain chamber and is equipped with a one-way drain valve. The opening and closing component is configured such that: when the float is at a preset low position, the negative pressure seal separates from the negative pressure interface, and the push rod separates from the sealing cap; when the float is at a preset high position, the negative pressure seal closes the negative pressure interface, and the push rod opens the sealing cap. [1][2] As described above, the integrated visual slag discharge and water discharge device includes a first observation window disposed on the side wall of the slag discharge chamber and a second observation window disposed on the side wall of the water discharge chamber.

[0010] As described above, the integrated visual slag discharge and water discharge device includes a slag discharge pipe protruding from the side wall of the tank, and the slag discharge pipe is connected to an openable cover plate; the diameter of the slag discharge port assembly is larger than the diameter of the air inlet.

[0011] As described above, the integrated visual slag discharge and water discharge device has a partition plate inside the box for defining the slag discharge chamber and the water discharge chamber. The bottom of the slag discharge chamber has a first inclined part for facilitating slag discharge, and the bottom of the water discharge chamber has a second inclined part for facilitating drainage. The high sides of the first inclined part and the second inclined part are connected to the partition plate.

[0012] Compared with the prior art, the present invention has the following advantages: 1. This device abandons the traditional easily clogged metal filter structure and adopts an inclined baffle as the core separation component. Utilizing the inertial impact and gravity sliding principle of high-speed airflow, it can efficiently intercept water droplets and coal slag in the mixed gas, and the inclined surface enables the self-cleaning sliding of impurities. This fundamentally avoids the problem of coal slime clogging the filter screen and increasing extraction resistance, and significantly extends the maintenance cycle.

[0013] 2. By installing observation components on the side wall of the tank, staff can intuitively monitor the slag height in the slag discharge chamber and the water level changes in the water discharge chamber without opening the tank. This allows maintenance personnel to accurately determine the timing of slag discharge and monitor the working status of the water discharge device, effectively avoiding the safety hazards of backflow caused by excessive slag clogging the pipes or water discharge device malfunction, and significantly improving inspection efficiency.

[0014] 3. This device highly integrates slag discharge and water discharge functions into a single enclosure, but achieves physical slag-water separation and compartmentalized treatment through connecting components. Most solid impurities are intercepted and precipitated in the slag discharge chamber, allowing only the upper clear liquid to overflow into the water discharge chamber. This design effectively protects the automatic water discharge mechanism within the water discharge chamber from coal slag blockage, significantly improving the operational reliability of the automatic water discharge system. Attached Figure Description To more clearly illustrate the technical solutions in the embodiments of the utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

[0015] Figure 1 This is a frontal perspective view of the structure in this embodiment; Figure 2 This is the left view of this embodiment; Figure 3 for Figure 1 Schematic diagram of the internal cross section along line AA. Detailed Implementation To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0016] This embodiment provides a visual integrated slag and water discharge device, which aims to solve the technical problems of incomplete impurity separation, dispersed equipment, and inability to intuitively monitor the internal status in existing coal mine gas extraction systems.

[0017] like Figures 1 to 3 As shown in the figure, the main structure of the visualized integrated slag discharge and water discharge device described in this embodiment includes a box 1. The box 1 can be welded from Q235 carbon steel or stainless steel plate to withstand the negative pressure environment of the underground gas pipeline. In order to achieve slag-water separation and compartmentalized treatment, the internal space of the box 1 is physically divided into two main functional chambers: a slag discharge chamber 11 and a water discharge chamber 12. The slag discharge chamber 11 is mainly used for the preliminary separation of the gas, solid, and liquid phases and the sedimentation of heavy coal slag, while the water discharge chamber 12 is used for the temporary storage and discharge of accumulated water. The slag discharge chamber 11 and the water discharge chamber 12 are not completely isolated, but are provided with a connecting component 13, so that the liquid after preliminary sedimentation can flow from the slag discharge chamber 11 to the water discharge chamber 12.

[0018] To facilitate connection to the underground pipeline system, an air inlet 2 is provided on one side wall of the housing 1 corresponding to the slag discharge chamber 11. This air inlet 2 is used to connect to the inflow end of the gas extraction pipeline via a flange or quick connector, introducing a gas mixture containing impurities such as water, coal slag, and coal slime into the housing. Simultaneously, an air outlet 3 is provided at the top of the housing 1, used to discharge the separated and purified gas and send it into the subsequent main extraction pipeline.

[0019] A gas-solid-liquid separation mechanism 4 is installed inside the slag discharge chamber 11. This mechanism efficiently intercepts impurities using the principle of physical impact. It includes an inclined baffle 41 positioned directly opposite the airflow direction of the air inlet 2. When high-speed flowing mixed gas is injected from the air inlet 2, it directly impacts the inclined baffle 41, forcing a drastic change in fluid direction. This utilizes inertia to intercept heavier solid particles and droplets.

[0020] An automatic water discharge mechanism 5 is installed inside the water discharge chamber 12. The function of this mechanism is to automatically control the discharge of accumulated water according to the changes in the water level inside the water discharge chamber 12, without the need for manual intervention, thus ensuring that the device can operate continuously and stably.

[0021] To address equipment maintenance and monitoring, this device is also equipped with slag discharge and observation structures.

[0022] Specifically, a slag discharge port assembly 6 is provided at the lower part of the slag discharge chamber 11 and communicates with the bottom space of the slag discharge chamber 11. After the intercepted coal slag settles and accumulates under gravity, the staff can use this assembly to perform slag cleaning operations periodically. In addition, an observation assembly 7 is also provided on the side wall of the box 1. The main body of this assembly is made of transparent material, so that the staff can directly observe the amount of slag accumulated in the slag discharge chamber 11 and the real-time water level in the water discharge chamber 12 inside the box 1 from the outside without opening the box, thereby accurately judging whether slag discharge or maintenance is required, greatly improving the efficiency of operation and maintenance.

[0023] Furthermore, as an optional implementation of this embodiment, the gas-solid-liquid separation mechanism 4 is disposed inside the slag discharge chamber 11. In terms of specific structural form, to optimize the guiding effect after airflow impact, the inclined baffle 41 is designed as an arc-shaped or arc-shaped plate structure, such as a curved plate with an arc-shaped cross-section. Considering that the underground environment of coal mines is usually accompanied by high humidity and a certain degree of corrosiveness, the inclined baffle 41 is preferably made of corrosion-resistant and impact-resistant metal materials, such as Q235 carbon steel with rust-proof treatment, or directly made of 304 stainless steel.

[0024] In terms of installation and fixing, the top end of the inclined baffle 41 is firmly fixed to the upper inner wall of the slag discharge chamber 11. Specifically, the fixing position can be the top wall of the slag discharge chamber 11 or a side wall near the top. The connection method can be full welding to ensure sealing and strength. The bottom end of the inclined baffle 41 is suspended, extending into the interior space of the slag discharge chamber 11 and inclined. Compared with traditional flat plate structures, this arc-shaped plate structure can form an impact surface with a certain envelope angle, which is beneficial for gathering splashed droplets and slag after impact towards the center of the plate, preventing them from escaping to the sides, thereby further improving separation efficiency.

[0025] In a preferred spatial layout implementation, the inclined baffle 41 is positioned on the airflow exit path of the air intake 2, with its surface directly blocking the air intake 2. Preferably, the concave surface of the inclined baffle 41 faces the air intake 2 to form an embracing interception; or, depending on the flow field design, its convex surface faces the air intake 2 to achieve diffusion and guidance.

[0026] Furthermore, to guide the intercepted solids and liquids to settle smoothly, the bottom end of the inclined baffle 41 extends downwards at an angle away from the air inlet 2. Given that the baffle body is arc-shaped, the angle of its inclination in this embodiment is defined based on its "chord plane": that is, the angle between the plane connecting the top and bottom ends of the inclined baffle 41 and the vertical plane is limited to the range of 20° to 45°. This angle range is determined based on fluid dynamics characteristics; if the angle is less than 20°, the rebound resistance is too large; if the angle is greater than 45°, the interception effect is weakened.

[0027] More specifically, as a preferred embodiment, the angle between the plane connecting the top and bottom ends of the inclined baffle 41 and the vertical plane is set to 23°. At this angle (referring to the chordal plane angle), after the high-speed gas-solid-liquid mixture ejected from the air inlet 2 impacts the concave surface (or convex surface) of the arc-shaped baffle, the fluid smoothly changes direction under the guidance of the arc. The kinetic energy of the heavier coal slag and water droplets rapidly decays, and under the combined action of gravity and the tangential force of the airflow, it quickly slides down the arc-shaped plate surface, which has an overall inclination of 23°, to the bottom of the slag discharge chamber 11. The lighter gas can smoothly bypass the lower or side edge of the baffle and flow upward to the air outlet 3. This design not only achieves a slag-water separation rate of over 90%, but also effectively prevents coal slime from adhering and scaling on the baffle surface, thereby ensuring long-term maintenance-free operation of the device.

[0028] Furthermore, in order to effectively prevent slag from clogging the subsequent water discharge mechanism while achieving communication between the two chambers, in terms of specific structural form, given that the slag discharge chamber 11 and the water discharge chamber 12 are physically separated within the housing 1, the communication component 13 is disposed on the common partition interface between the two chambers. In this specific embodiment, the partition interface is composed of a partition plate 14 (i.e., a partition wall structure inside the housing), and the communication component 13 is specifically implemented as an overflow pipe or flow channel passing through the partition plate 14.

[0029] As an optional implementation, the connecting component 13 can be a short metal pipe with open ends, such as a DN50 or DN[3][4]60 steel pipe, which is horizontally or slightly inclinedly welded and fixed to the partition plate 14, thereby connecting the spaces on both sides of the plate. As another alternative implementation, the connecting component 13 can also be a rectangular or circular flow channel opened at a specific height of the partition plate 14, and equipped with reinforcing ribs to ensure structural strength. Regardless of the form adopted, its inner diameter or flow area is designed to be not less than 1 / 2 of the flow area of ​​the air inlet 2, so as to ensure that the water flow can pass through in time during the peak period of gas extraction and avoid abnormal rise in the water level in the slag discharge chamber 11.

[0030] Furthermore, in order to achieve automatic grading of slag-water separation by utilizing the principle of gravity, the height of the water inlet of the connecting component 13 is set to be lower than the height of the air inlet 2 and higher than the height of the slag discharge component 6.

[0031] This specific height difference ensures that the overflow level of the connecting component 13 is always below the air inlet 2. Even in extreme conditions where water is not drained in time, causing the water level to rise, the water will overflow from the connecting component 13 to the drain chamber 12 first, without submerging the air inlet 2. This effectively prevents water from flowing back into the upstream gas extraction pipeline, ensuring the safety of the gas path of the extraction system.

[0032] Furthermore, this height difference creates a sediment-receiving zone of a certain depth between the connecting component 13, the bottom of the slag discharge chamber 11, and the slag discharge port component 6. When the mixed fluid impacts the baffle, the heavier slag and silt will quickly settle and accumulate in this bottom receiving zone; only the relatively clear liquid in the upper layer can overflow the higher connecting component 13 and enter the water discharge chamber 12. This design utilizes gravity difference to deposit large solid impurities that are prone to clogging into the slag discharge chamber 11, protecting the automatic water discharge mechanism 5 in the water discharge chamber 12 from the source and greatly extending the maintenance-free cycle of the device.

[0033] Furthermore, in this embodiment, the automatic water discharge mechanism 5 adopts a mechanical linkage three-way switching structure to achieve precise control of the air pressure state inside the water discharge chamber 12.

[0034] In terms of specific structural layout, the connecting component 13 includes a water inlet 131 that passes through the partition plate 14 to connect the slag discharge chamber 11 and the water discharge chamber 12. The automatic water discharge mechanism 5 specifically includes the following structure: An inlet check valve 51 is installed inside the drain chamber 12 and located on one side (i.e., the outlet end) of the inlet port 131. The inlet check valve 51 is configured to allow fluid to flow only from the slag discharge chamber 11 to the drain chamber 12, and will automatically close under reverse pressure differential. A valve stem 52 and a float 53 are arranged in a vertical manner within the drain chamber 12. To ensure the verticality of the movement trajectory of the valve stem 52 and its top component, a guide bracket is welded to the lower part or bottom of the drain chamber 12. This guide bracket slides with the valve stem 52, thereby restricting the valve stem 52 to move only vertically, preventing it from tilting or wobbling during movement, and ensuring that the top opening and closing component 55 is accurately aligned. The float 53 is not directly fixed but is movably sleeved on the valve stem 52 (i.e., the float 53 has a through hole in its center for the valve stem 52 to pass through). Under the buoyancy of the water, the float 53 can move upward relative to the valve stem 52. To drive the valve stem 52, a limit ring or limit block is provided on the valve stem 52 above the float 53. Its working logic is as follows: when the water level rises in the initial stage, the float 53 floats freely along the valve stem 52, while the valve stem 52 remains stationary; when the float 53 floats up to contact and abuts the limiting ring, the float 53 continues to rise and drives the valve stem 52 to move upward through the limiting ring, thereby triggering the gas path switching.

[0035] The valve body assembly 54 is disposed on the top wall of the housing 1 corresponding to the drain chamber 12, serving as the physical carrier for gas path switching. Specifically, the valve body assembly 54 includes a negative pressure interface 541, located at the center of the assembly, for communicating with an external negative pressure environment, such as the negative pressure zone of the gas extraction main pipeline or the slag discharge chamber 11, serving as the air intake source for maintaining the negative pressure of the drain chamber 12.

[0036] An atmospheric connection component 542 is located beside the negative pressure interface 541 and can be symmetrically or unilaterally installed. This component includes a vertically upward-facing vent pipe 5421 and a sealing cap 5422 covering the top of the vent pipe 5421. When not open, the sealing cap 5422 tightly seals the vent pipe 5421 by its own weight or negative pressure suction, isolating it from the atmosphere.

[0037] The opening / closing element 55 is installed at the top of the valve stem 52 and moves up and down synchronously with the valve stem 52 to cooperate with the valve body assembly 54 for switching the air path. The opening / closing element 55 specifically includes: a negative pressure seal 551, which can be a flat rubber pad and is located corresponding to the negative pressure interface 541, used to seal the interface; and a push rod 552, which can be a straight metal tube or a push pin and is located corresponding to the sealing cap 5422, used to push the sealing cap upward.

[0038] The drain outlet 56 is located at the lowest point of the bottom of the drain chamber 12, and the drain check valve 57 is provided at the drain outlet 56. The drain check valve 57 is also configured to be unidirectional (only outflow, no inflow) and can remain normally closed under negative pressure adsorption.

[0039] Furthermore, to improve the sealing reliability and positioning accuracy when the negative pressure seal 551 and the negative pressure interface 541 are engaged, this embodiment also provides a magnetically assisted sealing structure on the valve body assembly and the opening / closing element. Specifically, a first magnetic element (not shown in the figure), such as a ring-shaped permanent magnet, is provided on or around the end face of the negative pressure interface 541; correspondingly, a second magnetic element (not shown in the figure), such as an attracting magnet or a magnetic conductive sheet, is provided at or on the back of the negative pressure seal 551 of the opening / closing element 55. The pair of magnetic elements are configured such that when the opening / closing element 55 rises to a near-closed position, the first magnetic element and the second magnetic element attract each other, using magnetic attraction to help the negative pressure seal 551 fit tightly against the negative pressure interface 541, eliminating minute gaps caused by airflow disturbances or buoyancy fluctuations.

[0040] The dynamic operation process and principle of the automatic water discharge mechanism 5 in this embodiment are as follows: The first stage is the water storage and negative pressure maintenance stage (low water level state). When there is no water in the drain chamber 12 or the water level is at a preset low level, the float 53 moves the valve stem 52 and the top opening and closing element 55 downwards under its own weight. In this state, the negative pressure seal 551 on the opening and closing element 55 separates from the negative pressure interface 541, making the negative pressure interface 541 open and continuously drawing air out of the drain chamber 12; at the same time, the top rod 552 on the opening and closing element 55 falls back and separates from the sealing cap 5422. The sealing cap 5422 tightly seals the vent pipe 5421 under its own weight or suction, cutting off the atmospheric source. Therefore, the drain chamber 12 is connected to the negative pressure environment through the open negative pressure interface 541, maintaining a stable negative pressure state. Affected by this negative pressure, the external atmospheric pressure is greater than the pressure inside the tank, and the bottom drain check valve 57 is firmly sucked in and in the closed state. At this time, the water separated in the slag discharge chamber 11 flows continuously into the water discharge chamber 12 through the water inlet 131 under the action of gravity and pressure difference for accumulation.

[0041] The second stage is the air circuit switching and water discharge stage (high water level state). As the water accumulates, when the water level rises to the preset high level, the buoyancy generated by the float ball 53 overcomes the weight of the component and the negative pressure adsorption force, driving the valve stem 52 to move the opening and closing element 55 upward. During this upward movement, the negative pressure seal 551 on the opening and closing element 55 first abuts against and seals the negative pressure interface 541. At this time, the opposite magnetic pair (i.e., the first magnetic element and the second magnetic element) located at the negative pressure interface 541 and the opening and closing element 55 attract each other, using magnetic attraction to firmly lock the negative pressure seal 551 in the sealing position, ensuring the precise fit of the negative pressure seal, thereby physically cutting off the connection between the water discharge chamber 12 and the negative pressure source; synchronously or immediately afterward, the push rod 552 on the opening and closing element 55 pushes the sealing cap 5422 upward, allowing outside air to quickly rush into the water discharge chamber 12 through the vent pipe 5421. Once the air enters, the air pressure in the water discharge chamber 12 instantly returns to normal pressure (atmospheric pressure). At this moment, a significant pressure difference is created between the drain chamber 12 (at normal pressure) and the slag discharge chamber 11 (negative pressure). This pressure difference forces the inlet check valve 51 to instantly press against the valve seat, thereby sealing the inlet port 131 and preventing atmospheric backflow. Simultaneously, since the drain chamber 12 is no longer under negative pressure, the drain check valve 57 at the bottom is no longer constrained by suction. Under the force of gravity, the water flow opens the drain check valve 57 and is rapidly discharged from the drain port 56.

[0042] The third stage is the reset cycle. As the accumulated water is drained, the water level continues to drop, and the buoyancy generated by the float 53 gradually decreases until it disappears. At this time, the float 53 and valve stem 52 assembly generate a downward pull under their own weight. When this downward gravitational pull accumulates to a level greater than the sum of the magnetic attraction force between the magnetic components (i.e., the first magnetic component and the second magnetic component) and the negative pressure adsorption force, the opening and closing component 55 is pulled down instantly. The push rod 552 retracts, and the sealing cap 5422 resets and closes; the negative pressure seal 551 and the negative pressure interface 541 separate instantly (magnetic separation), and the negative pressure interface 541 reopens to pump air. The device quickly returns to the negative pressure state and enters the next water storage cycle.

[0043] Through the above structure and logic, this device can complete continuous and automatic slag discharge and water release operations by only utilizing water level rise and fall and pressure difference changes without consuming electrical energy.

[0044] It should be noted that the specific mechanical structure of the automatic water discharge mechanism 5 described in this embodiment is only an illustrative preferred implementation, intended to clearly illustrate the working principle of the device using water level to control the gas path switching, and should not be considered as a limitation on the scope of protection of this application. In the field of coal mine gas extraction technology, negative pressure automatic water dischargers that use buoyancy or liquid level signals to break the vacuum to achieve water discharge are relatively mature components in the prior art. Those skilled in the art will understand that in practical engineering applications, any mechanical structure (such as lever-driven or magnetically coupled structures) or even explosion-proof electromechanical control structure that can achieve the core functional logic of "closing the air inlet to maintain negative pressure in the water discharge chamber when the water level is low and opening the air inlet to connect with the atmosphere when the water level is high" can be used as an equivalent alternative to the automatic water discharge mechanism 5 of this device in this application.

[0045] Furthermore, in order to enable staff to intuitively and in real time grasp the internal operating status of the device, the observation component 7 is subdivided into two independently set observation units according to the different internal functional partitions: namely, the first observation window 71 set on the side wall of the slag discharge chamber 11, and the second observation window 72 set on the side wall of the water discharge chamber 12.

[0046] Considering the unique characteristics of the negative pressure, humidity, and potential methane environment in underground coal mines, both the first observation window 71 and the second observation window 72 are preferably made of high-strength, impact-resistant, and highly transparent materials, such as 10mm-20mm thick transparent acrylic sheets or explosion-proof tempered glass. Regarding the fixing method, to ensure the airtightness of the enclosure 1 under negative pressure conditions, the observation windows are not directly glued together, but rather secured by metal flange frames. Specifically, mounting flanges are installed at prefabricated openings on the side walls of the enclosure 1, with corrosion-resistant rubber gaskets placed between the transparent sheet and the flanges, and are evenly tightened using multiple high-strength bolts. This detachable structure not only ensures reliable sealing but also facilitates the replacement of worn or blurred viewing window glass in the future.

[0047] Furthermore, the slag discharge port assembly 6 includes a slag discharge pipe 61 protruding from the lower part of the side wall of the housing 1. The end of the slag discharge pipe 61 is connected to an openable cover plate 62, and a rubber sealing gasket is provided at the connection to ensure airtightness. To facilitate the cleaning of large pieces of coal slag and sludge, the diameter of the slag discharge pipe 61 is designed to be larger than the diameter of the air inlet port 2. This large-diameter design allows workers to easily insert shovels and other tools into the bottom of the slag discharge chamber 11 for thorough cleaning after opening the cover plate 62.

[0048] More specifically, the first observation window 71 is positioned to correspond to the lower area of ​​the slag discharge chamber 11, particularly the slag accumulation area below the inclined baffle 41. This allows inspectors to directly observe the height and shape of the coal slag and silt accumulation within the slag discharge chamber 11. When the slag accumulation reaches the warning height (e.g., obscuring half of the viewing window), staff can promptly open the cover 62 of the slag discharge pipe 61 for cleaning, avoiding blind slag discharge or blockages caused by untimely slag discharge. The second observation window 72 is positioned to correspond to the upper-middle area of ​​the water discharge chamber 12, primarily covering the travel range of the float 53. Through this window, staff can clearly see the real-time water level changes within the water discharge chamber 12 and the rising and falling motion of the float 53. If the water level is found to be high but the float has not risen (possibly stuck), or the float has risen but water is not discharged (possibly a valve malfunction), staff can immediately detect and address the problem, greatly improving the efficiency and safety of equipment operation and maintenance.

[0049] Furthermore, as a preferred embodiment of this invention, the bottom of this device abandons the traditional horizontal base plate and utilizes a vertically arranged partition plate 14 as a central support frame to construct a bidirectional inclined bottom surface that automatically converges under gravity. Specifically, the slag discharge chamber 11 located on one side of the partition plate 14 has a first inclined portion 111 at its bottom; the water discharge chamber 12 located on the other side of the partition plate 14 has a second inclined portion 121 at its bottom. The higher sides (i.e., the higher edges) of the first inclined portion 111 and the second inclined portion 121 are directly welded to the bottom edge of the partition plate 14, while their lower sides (i.e., the lower edges) extend downwards towards the opposite outer walls or corners on both sides of the tank 1. This structure, high in the middle and low on both sides, forms a ridge-like diversion structure at the bottom of the tank 1. For the slag discharge chamber 11, the settled coal slag and silt, after falling onto the first inclined section 111, cannot remain at the base of the intermediate partition plate 14. Instead, they automatically slide outwards along the inclined surface under gravity, eventually converging at the slag discharge pipe 61 located at the lowest point. This ensures that when workers open the cover plate 62 to clean the slag, the accumulated slag is already concentrated at the outlet of the slag discharge pipe 61, greatly facilitating the cleaning operation and avoiding cleaning dead zones deep inside the chamber. On the other hand, for the water discharge chamber 12, when the automatic water discharge mechanism 5 operates to drain water, the accumulated water flows completely along the second inclined section 121 to the drain outlet 56 located at the lowest point, ensuring that the water discharge chamber 12 can be completely emptied without any residual stagnant water, effectively preventing bacterial growth or metal corrosion caused by long-term water retention.
