Abstract
Description
Technical Field
[0001] This utility model relates to the field of monitoring technology, and in particular to a coal mine gas dust removal and dehydration monitoring device. Background Technology
[0002] Monitoring refers to a series of activities involving the observation, measurement, recording, and analysis of relevant data on a specific object or environment over a long period of time, continuously or periodically.
[0003] In existing technologies, conventional monitoring methods mostly involve filtering and then extracting samples for experiments. This results in the lack of a good device for collecting and processing dust. Furthermore, the collection device cannot be quickly disassembled, leading to inaccurate monitoring data. The inability to quickly disassemble and install the acquisition device also delays the monitoring process. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a coal mine gas dust removal and dehydration monitoring device.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a coal mine gas dust removal and dehydration monitoring device, comprising a transmission pipeline support frame, a transmission pipeline fixedly connected to the top of the transmission pipeline support frame, a dust collection bin fixing block fixedly connected to the middle of the transmission pipeline, a cylindrical fixing base fixedly connected to the bottom of the dust collection bin fixing block, fixing grooves provided on the symmetrical sides of the bottom of the cylindrical fixing base, disassembly through grooves provided on the other symmetrical sides of the bottom of the cylindrical fixing base, a dust inlet provided at the bottom of the dust collection bin fixing block, a rotating groove provided at the top of the cylindrical fixing base, a groove fixing block slidably connected inside the rotating groove, a dust collection bin connecting block fixedly connected to the side of the groove fixing block, and a dust collection bin fixedly connected to the bottom of the dust collection bin connecting block.
[0006] Preferably, a rotating hollow cylinder is rotatably connected to the side end of the transmission pipe, and a rotating pipe is fixedly connected to the side end of the rotating hollow cylinder away from the transmission pipe. A snap-fit chamber body is fixedly connected to the circumference of the rotating pipe, and a snap-fit chamber door is slidably connected to the side end of the snap-fit chamber body. A connecting cylinder is fixedly connected to the side end of the rotating pipe away from the rotating hollow cylinder. The connecting cylinder is driven to rotate by an external motor, and the external motor is fixed by a motor mounting base. In the prior art, small particles are often collected using high-density materials or processed using high-end equipment, which leads to increased costs. Firstly, the cost is high because the purchase price of the instruments is expensive, increasing the initial equipment investment cost for coal mining enterprises. Secondly, the maintenance and repair costs of high-end instruments are also high. Specialized technicians and accessories represent a significant expense for enterprises. Operation requires professionally trained personnel, demanding high levels of skill and knowledge from operators. Failure to do so may result in improper instrument use, damage, or failure to achieve the desired dust and water removal effects. Furthermore, the operating environment is critical; high-end instruments may have strict requirements regarding temperature, humidity, and dust concentration. The complex and variable environment of underground coal mines means that unsuitable conditions can negatively impact instrument performance, leading to frequent malfunctions. To address these issues, this invention employs a rotary dehydration and dust removal structure. Methane gas often contains a large amount of dust particles, which can cause wear and other adverse effects on subsequent gas utilization equipment. For example, in gas power generation equipment, dust particles can enter the combustion chamber of a gas turbine or internal combustion engine, accelerating wear on the combustion chamber walls, turbine blades, and other components, shortening the equipment's lifespan. Cyclone separation dust removal effectively removes most of the dust from the methane gas, resulting in purer gas and reducing equipment maintenance and replacement costs. Moisture in the methane gas also presents numerous problems. If the gas contains a large amount of moisture, condensation may occur during transportation due to temperature changes, potentially clogging the pipelines. Furthermore, excessive moisture reduces combustion efficiency during gas combustion. For example, when gas is used as fuel in industrial furnaces, the presence of moisture absorbs heat generated during combustion, used for evaporation and heating, thus reducing the effective heat needed for heating materials. Cyclone separation and dehydration can reduce the moisture content of the gas, increase its calorific value, and ensure stability and efficiency during transportation and utilization.
[0007] Preferably, the top and bottom of the snap-fit chamber body are fixedly connected to rotating shaft connecting blocks, and the side end of the rotating shaft connecting block is rotatably connected to the snap-fit chamber door. The side end of the snap-fit chamber door is fixedly connected to a snap-fit. The inner wall of the snap-fit chamber body is provided with a groove. In the prior art, the chamber body is mostly slidably connected, which makes it difficult to completely avoid gaps in the slid connection. Even if the design is very precise, under long-term use or under conditions such as vibration and pressure changes, small gaps may still appear at the connection, which will lead to gas or liquid leakage and affect the sealing performance of the equipment. To address this problem, this utility model adopts a snap-fit structure. In some equipment for storing gases and liquids, the high sealing performance of the snap-fit can ensure that the internal substances will not leak. Due to the good sealing performance of the snap-fit, the internal of the equipment is less affected by external influences, so the maintenance frequency and cost of the equipment will be reduced accordingly. In equipment involving hazardous substances, such as storage and transportation equipment for flammable and explosive gases, the high sealing performance of the snap-fit is crucial.
[0008] Preferably, the inner wall of the transmission pipe is provided with an inclined ramp, and the top of the dust collection bin fixing block is provided with a recessed collection port. The inclined ramp helps to collect large particles.
[0009] Preferably, an absorbent sponge block is fixedly connected to the bottom of the snap-lock compartment door. The absorbent sponge can collect small particles and moisture, and is also low in cost.
[0010] Preferably, the dust collection bin is fixedly connected to an anti-slip pad on its periphery to increase friction and prevent the dust collection bin from falling off during rotation.
[0011] Preferably, the main body of the snap-fit compartment and the snap-fit compartment door are provided with sealing rings around them to increase the sealing effect and prevent the leakage of dust, moisture and gas.
[0012] Beneficial effects:
[0013] 1. In existing technologies, conventional monitoring methods mostly involve filtering and then extracting samples for experiments. This results in a lack of effective dust collection and processing devices, and the collection devices cannot be quickly disassembled, leading to inaccurate monitoring data. Furthermore, the inability to quickly disassemble and install the collection device also delays the monitoring process. To address these issues, this utility model employs a quick-disassembly device. When the collection device malfunctions, such as internal filter blockage or pipe damage, quick disassembly allows personnel to promptly repair or replace the faulty parts. In scenarios requiring continuous collection, quick disassembly reduces the device's downtime. For devices collecting hazardous substances, such as radioactive materials or toxic gases, quick disassembly shortens the time personnel are exposed to dangerous environments, reducing operational risks.
[0014] 2. In existing technologies, small particles are often collected using high-density materials or processed through high-end equipment, which increases costs. Firstly, the cost is high; the purchase price of the instruments is expensive, increasing the initial equipment investment costs for coal mining enterprises. Furthermore, the maintenance and repair costs of high-end instruments are also high, requiring professional technicians and specialized spare parts, which is a significant expense for enterprises. Operators need to be professionally trained, requiring a high level of technical and knowledge expertise; otherwise, they may not be able to operate the instruments correctly, or even damage them or fail to achieve the expected dust removal and dehydration effects. Secondly, high-end instruments have strict requirements regarding the operating environment, such as temperature, humidity, and dust concentration. The underground environment of coal mines is complex and variable; if environmental conditions do not meet the requirements, the performance of the instruments may be affected, leading to frequent malfunctions. To address these issues, this utility model adopts a rotating dehydration and dust removal structure. Methane often contains a large amount of dust particles, which can cause wear and other adverse effects on subsequent methane utilization equipment. For example, in gas power generation equipment, dust particles can enter the combustion chamber of a gas turbine or internal combustion engine, leading to accelerated wear on components such as the combustion chamber walls and turbine blades, thus shortening the equipment's lifespan. Cyclone separation and dust removal can effectively remove most of the dust from the gas, making it purer and reducing equipment maintenance and replacement costs. Moisture in the gas also poses numerous problems. If the gas contains a large amount of moisture, it may condense during transportation due to temperature changes, causing blockages in pipelines. Furthermore, excessive moisture reduces combustion efficiency during gas combustion. When gas is used as fuel in industrial furnaces, the presence of moisture absorbs heat generated during combustion, used for evaporation and heating, reducing the effective heat needed for heating materials. Cyclone separation and dehydration can reduce the moisture content of the gas, increase its calorific value, and ensure its stability and efficiency during transportation and utilization.
[0015] 3. In existing technologies, most storage chambers use sliding connections, which makes it difficult to completely avoid gaps. Even with precise design, tiny gaps may still appear at the connection points during long-term use or under conditions such as vibration and pressure changes. This can lead to gas or liquid leakage and affect the equipment's sealing performance. To address this issue, this invention adopts a snap-fit structure. In some equipment storing gases and liquids, the high sealing performance of the snap-fit ensures that the internal substances will not leak. Due to the good sealing performance of the snap-fit, the internal equipment is less affected by external influences, thus reducing the frequency and cost of equipment maintenance. In equipment involving hazardous materials, such as storage and transportation equipment for flammable and explosive gases, the high sealing performance of the snap-fit is crucial.

[0030] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:
[0032] Reference Figure 1-11 A coal mine gas dust removal and dehydration monitoring device includes a transmission pipeline support frame 1, a transmission pipeline 2 fixedly connected to the top of the transmission pipeline support frame 1, an inclined ramp 409 formed on the inner wall of the transmission pipeline 2, a dust collection bin fixing block 4 with a recessed collection port 410 at the top, the inclined ramp facilitating the collection of large particles, a dust collection bin fixing block 4 fixedly connected to the middle of the transmission pipeline 2, and a cylindrical fixing base 401 fixedly connected to the bottom of the dust collection bin fixing block 4, with fixing grooves 402 formed on the symmetrical sides of the bottom of the cylindrical fixing base 401. The bottom of the fixed base 401 is provided with symmetrical disassembly grooves 403. The bottom of the dust collection bin fixed block 4 is provided with a dust inlet 404. The top of the cylindrical fixed base 401 is provided with a rotating groove 411. The groove fixed block 406 is slidably connected inside the rotating groove 411. The side of the groove fixed block 406 is fixedly connected with a dust collection bin connecting block 405. The bottom of the dust collection bin connecting block 405 is fixedly connected with a dust collection bin 407. The periphery of the dust collection bin 407 is fixedly connected with an anti-slip pad 408 to increase friction and prevent the dust collection bin from falling off during rotation.
[0033] A rotating hollow cylinder 507 is rotatably connected to one side of the transmission pipe 2. A rotating pipe 506 is fixedly connected to the side of the rotating hollow cylinder 507 away from the transmission pipe 2. A snap-fit chamber body 501 is fixedly connected to the circumference of the rotating pipe 506. A snap-fit chamber door 503 is slidably connected to the side of the snap-fit chamber body 501. A connecting cylinder 302 is fixedly connected to the side of the rotating pipe 506 away from the rotating hollow cylinder 507. The connecting cylinder 302 is driven to rotate by an external motor, which is fixed by a motor mounting base 301. This utility model adopts a rotating dehydration and dust removal structure. Gas often contains a large amount of dust particles, which can have adverse effects such as wear on subsequent gas utilization equipment. For example, in gas power generation equipment, dust particles can enter the combustion chamber of a gas turbine or internal combustion engine, leading to accelerated wear on components such as the combustion chamber wall and turbine blades, and shortening the service life of the equipment. Cyclone separation effectively removes most of the dust from methane gas, making it purer and reducing equipment maintenance and replacement costs. However, moisture in methane gas can cause numerous problems. If the gas contains a large amount of moisture, condensation may occur during transportation due to temperature changes, clogging pipelines. Furthermore, excessive moisture reduces combustion efficiency during methane combustion. For example, when methane is used as fuel in industrial furnaces, the presence of moisture absorbs heat generated during combustion, used for evaporation and heating, reducing the effective heat needed for heating materials. Cyclone separation dehydration reduces the moisture content of methane, increases its calorific value, and ensures stability and efficiency during transportation and utilization.
[0034] The snap-fit chamber body 501 has a rotating shaft connecting block 502 fixedly connected to its top and bottom. The snap-fit chamber door 503 is rotatably connected to the side of the rotating shaft connecting block 502. Sealing rings are provided around the snap-fit chamber body 501 and the snap-fit chamber door 503 to increase the sealing effect and prevent the leakage of small dust, moisture, and gas. A water-absorbing sponge block 505 is fixedly connected to the bottom of the snap-fit chamber door 503. The water-absorbing sponge can collect small particles and moisture, and is low in cost. A snap 504 is fixedly connected to the side of the snap-fit chamber door 503. The inner wall of the snap-fit chamber body 501 has a groove. This utility model adopts a snap-fit structure. In some equipment for storing gases and liquids, the high sealing performance of the snap-fit can ensure that the internal substances will not leak. Due to the good sealing performance of the snap-fit, the internal of the equipment is less affected by external factors, so the maintenance frequency and cost of the equipment will be reduced accordingly. In equipment involving hazardous materials, such as storage and transportation equipment for flammable and explosive gases, the high sealing performance of the snap-fit is crucial.
[0035] The working principle of this utility model is as follows: When it is necessary to monitor the dust removal and dehydration standards in gas, gas is introduced into the transmission pipeline 2. Large dust particles, due to their greater weight, pass through the inclined ramp 409 and the recessed collection port 410, entering the dust collection chamber 407 through the dust inlet 404. When a certain amount is collected, the conveying is stopped. At this time, the operator manually presses the dust collection chamber 407 upwards while simultaneously rotating it so that the groove fixing block 406 rotates from the fixing groove 402 to the disassembly through groove 403. At this point, the operator can release the pressure, and the dust collection chamber 407 detaches from the cylindrical fixing base 401, thus disassembling the dust collection chamber 407. Then, according to... The actual content is monitored by calculation to remove large particles from the gas. Small particles and moisture continue to be transported to the rotating pipe 506. The external motor is started, and the connecting cylinder 302 rotates, which drives the rotating hollow cylinder 507 to rotate. The high-speed rotation removes small particles and moisture. Moisture and small dust are adsorbed onto the water-absorbing sponge block 505. After a certain period of collection, the rotating shaft connecting block 502 is engaged. Due to the deformation of the rotating shaft connecting block 502 by external force, the buckle 504 disengages from the groove, realizing the opening and closing of the rotating shaft connecting block 502. The staff can then extract the required monitoring body from the water-absorbing sponge block 505.
