Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coal mine ventilation technology, and in particular relates to a safety ventilation device for coal mines. Background Technology
[0002] A coal mine is a general term for geological areas rich in coal resources and their supporting mining and processing facilities. Its core function is to extract coal resources from underground or the surface through reasonable mining technology, and then wash, process, and use them as energy or industrial raw materials. From a geological perspective, coal mines are sedimentary deposits formed by ancient plants through peatification, lignification, bituminous coalification, and anthracite coalification under geological processes. According to the burial depth, they can be divided into open-pit coal mines and underground coal mines. In order to ensure the normal operation of coal mines, it is necessary to continuously ventilate the mine shafts, supplying fresh air to the mine through mechanical or natural means, expelling toxic and harmful gases, dust, and residual heat, maintaining a suitable working environment underground, and ensuring the safety of workers and the normal operation of production.
[0003] Because coal mine operations involve significant dust, the air delivered by ventilation systems often contains high levels of dust. This can negatively impact the health and safety of workers during their work. Therefore, this paper proposes a safety-oriented ventilation system for coal mines. Utility Model Content
[0004] The purpose of this invention is to provide a safe ventilation device for coal mines that solves the existing problems.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a safety ventilation device for coal mines, comprising: a mounting plate, an air inlet pipe mounted on one side of the mounting plate, an air outlet at the top of the air inlet pipe, and the air outlet being fixedly connected to the side wall of the mounting plate; an air outlet pipe fixedly mounted at one end of the air outlet through the side wall of the mounting plate; a primary dust removal mechanism fixedly mounted on the side of the mounting plate away from the air inlet pipe, with one end of the primary dust removal mechanism passing through the side wall of the mounting plate and fixedly connected to one end of the air inlet pipe; a secondary dust removal mechanism fixedly mounted at the end of the primary dust removal mechanism away from the mounting plate; and a connecting pipe fixedly mounted at the end of the secondary dust removal mechanism away from the primary dust removal mechanism; the primary dust removal mechanism includes a mounting base fixedly mounted on the side of the mounting plate away from the air inlet pipe, with a plurality of bases fixedly mounted at equal intervals at the bottom of the mounting base, and a plurality of top seats fixedly mounted above each base, with the top seats fixedly connected to the inner wall of the mounting base.
[0006] Furthermore, the base and top seat are staggered, with an alternating arrangement along the airflow direction within the flow channel cavity. The upper surface of the base protrudes above the flow channel reference surface, while the lower surface of the top seat is below the top reference surface of the flow channel. The base and top seat partially overlap in the width direction of the flow channel and are staggered vertically in the height direction. This staggered arrangement forces the air to be processed to pass sequentially around the upper edge of the base and the lower edge of the top seat within the flow channel area formed by the base and top seat, creating at least two continuous flow channel bends, thereby forcibly changing the airflow direction within the flow channel.
[0007] Furthermore, the primary dust removal mechanism also includes a connecting pipe fixedly installed at the bottom of the mounting base. A collection seat is slidably connected to the bottom of the connecting pipe, and several fixed seats are symmetrically fixedly installed at the bottom of the connecting pipe. An auxiliary spring is provided inside each fixed seat, and a limiting rod is slidably connected inside each fixed seat. The limiting rod is inserted into the collection seat, and the end of the limiting rod away from the collection seat is fixedly connected to the mounting frame. When the device is working, the air inlet pipe delivers external air into the interior of the mounting base. At this time, the air will come into contact with the base and top seat, and the direction of airflow will influence the airflow. The dust particles undergo a rapid change, impacting the surfaces of the base and top seat under inertial force. After losing kinetic energy, they settle along the surfaces of the base and top seat into the connecting pipe at the bottom. Subsequently, they fall into the collection seat. When a certain amount has been collected, the mounting frame can be pulled upwards in conjunction with the limiting rod, compressing the auxiliary spring and releasing the limiting rod from restricting the collection seat, allowing for replacement and cleaning. After cleaning, the collection seat is reset, and then the auxiliary spring drives the limiting rod and mounting frame to reset, thus restricting the collection seat and further improving the stability and convenience of the device during use.
[0008] Furthermore, the collection seat has an internal receiving groove, and the top of the receiving groove is symmetrically provided with inclined grooves. The receiving groove inside the collection seat can collect the collected dust in a concentrated manner, while the inclined grooves at the top of the receiving groove make it convenient for workers to empty the collection seat, so that the primary dust removal mechanism can be used for a long time.
[0009] Furthermore, the secondary dust removal mechanism includes an installation pipe fixedly installed at one end of the mounting base, a flow divider plate fixedly installed at the top of the installation pipe, a water inlet pipe fixedly installed at the top of the flow divider plate, a plurality of nozzles fixedly installed at equal intervals through the side wall of the installation pipe at one end of the flow divider plate, a filter plate fixedly installed inside the installation pipe, and guide pipes fixedly installed at equal intervals at the bottom of the installation pipe. The bottom end of the guide pipe is fixedly connected to the top end of the water outlet pipe. When secondary dust removal is required, the air to be treated enters the cavity of the installation pipe along a preset airflow path, forming a stable airflow field. At the same time, the water inlet pipe delivers clean water to the flow divider plate according to a preset flow rate. The flow divider plate, through its internal opening... The designed diversion channel and flow equalization structure evenly distribute water to multiple nozzles arranged circumferentially along the inner wall of the installation pipe. The nozzles adopt a high-pressure atomization design, which transforms the diverted water into fine water mist with a particle size of 5-50μm. The water mist forms a uniformly covered atomized dust removal area inside the installation pipe. When the air to be treated flows through the atomized dust removal area, the dust particles remaining in the air come into full contact with the atomized water droplets. Through inertial collision, Brownian motion, and water film adsorption, the dust particles are efficiently captured, forming dust-laden water droplets. The dust-laden water droplets settle downwards under the action of gravity and fall onto the filter plate inclined at the bottom of the installation pipe. Subsequently, the dust-laden water flows along the filter plate to the guide pipe, and then flows steadily into the outlet pipe, and is finally discharged outside the equipment.
[0010] Furthermore, the top of the filter plate is provided with a guide groove arranged in a grid pattern, and the filter plate is provided with a number of perforations at equal intervals that are installed and matched with the guide pipe. The guide groove at the top of the filter plate can guide the mixed liquid after dust removal in an orderly manner, guiding the mixed liquid to the perforations on the filter plate, and then flowing into the outlet pipe through the guide pipe.
[0011] Furthermore, the installation pipe is symmetrically and fixedly installed with partition seats inside. The partition seats can prevent the atomized water vapor sprayed by the nozzle from being intercepted and restricted when the secondary dust removal mechanism is performing dust suppression, and prevent the atomized water vapor from flowing randomly, thereby further improving the safety of the device during use.
[0012] This utility model has the following beneficial effects: 1. This utility model can quickly intercept and reduce larger dust particles in the air through the setting of the primary dust removal mechanism. The multiple sets of bases and top seats can quickly remove dust from the air. In addition, each set of bases and top seats is equipped with a collection seat, which can quickly collect dust and prevent dust from accumulating inside the device, thereby further improving the dust removal effect of the device.
[0013] 2. This utility model can quickly perform secondary dust removal on the air through the setting of a two-stage dust removal mechanism, which reduces the dust particles in the air and further improves the cleanliness of the air. The setting of the primary dust removal mechanism and the secondary dust removal mechanism can quickly clean up dust of all sizes in the air, making the air more usable.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-6 This utility model is a safety ventilation device for coal mines, comprising: a mounting plate 1, an air inlet pipe 2 installed on one side of the mounting plate 1, an air outlet 3 at the top of the air inlet pipe 2, and the air outlet 3 being fixedly connected to the side wall of the mounting plate 1; an air outlet pipe 4 fixedly installed at one end of the air outlet 3 passing through the side wall of the mounting plate 1; a primary dust removal mechanism 5 fixedly installed on the side of the mounting plate 1 away from the air inlet pipe 2, and one end of the primary dust removal mechanism 5 passing through the side wall of the mounting plate 1 and fixedly connected to one end of the air inlet pipe 2; a secondary dust removal mechanism 6 fixedly installed at the end of the primary dust removal mechanism 5 away from the mounting plate 1; and a connecting pipe 7 fixedly installed at the end of the secondary dust removal mechanism 6 away from the primary dust removal mechanism 5; the primary dust removal mechanism 5 includes a mounting base 8 fixedly installed on the side of the mounting plate 1 away from the air inlet pipe 2; a plurality of bases 9 are fixedly installed at equal intervals at the bottom of the inner side of the mounting base 8; a plurality of top seats 10 are provided above each of the bases 9, and the top seats 10 are fixedly connected to the inner wall of the mounting base 8.
[0020] The base 9 and top seat 10 are staggered, with the base 9 and top seat 10 arranged alternately inside the flow channel cavity along the airflow direction. The upper surface of the base 9 protrudes above the flow channel reference surface, while the lower surface of the top seat 10 is lower than the top reference surface of the flow channel. The base 9 and top seat 10 partially overlap in the width direction of the flow channel and form a staggered fit in the height direction. This staggered arrangement forces the air to be processed to pass sequentially around the upper edge of the base 9 and the lower edge of the top seat 10 as it flows through the flow channel area formed by the base 9 and top seat 10, creating at least two continuous flow channel bends, thereby forcibly changing the airflow direction within the flow channel.
[0021] The primary dust removal mechanism 5 also includes a connecting pipe 12 fixedly installed at the bottom of the mounting base 8. A collection seat 13 is slidably connected to the bottom of the connecting pipe 12. Several fixed seats 14 are symmetrically fixedly installed at the bottom of the connecting pipe 12. An auxiliary spring 15 is provided inside each fixed seat 14. A limiting rod 16 is slidably connected inside each fixed seat 14, and the limiting rod 16 is inserted into the collection seat 13. The end of the limiting rod 16 away from the collection seat 13 is fixedly connected to the mounting frame 17. When the device is working, the air inlet pipe 2 delivers external air into the interior of the mounting base 8. At this time, the air will come into contact with the base 9 and the top seat 10. Due to the rapid airflow direction... The dust particles, under the influence of inertial force, impact the surfaces of the base 9 and top seat 10. After losing kinetic energy, they sink along the surfaces of the base 9 and top seat 10 into the connecting pipe 12 at the bottom. Subsequently, they fall into the collection seat 13. When the collection seat 13 has collected a certain amount, the mounting frame 17 can be pulled upward in conjunction with the limiting rod 16 to compress the auxiliary spring 15, thereby releasing the limiting rod 16 from restricting the collection seat 13, so that the collection seat 13 can be replaced and cleaned. After cleaning, the collection seat 13 is reset. Then, the auxiliary spring 15 drives the limiting rod 16 and the mounting frame 17 to reset, thereby restricting the collection seat 13 and further improving the stability and convenience of the device during use.
[0022] The collection seat 13 has an internal receiving groove, and the top of the receiving groove is symmetrically provided with inclined grooves. The receiving groove inside the collection seat 13 can collect the collected dust in a concentrated manner, and the inclined grooves at the top of the receiving groove make it convenient for the staff to empty the collection seat 13, so that the primary dust removal mechanism 5 can be used for a long time.
[0023] The secondary dust removal mechanism 6 includes an installation pipe 18 fixedly installed at one end of the mounting base 8, a diverter plate 19 fixedly installed at the top of the installation pipe 18, a water inlet pipe 20 fixedly installed at the top of the diverter plate 19, a plurality of nozzles 21 fixedly installed at equal intervals through the side wall of the installation pipe 18 at one end of the diverter plate 19, a filter plate 22 fixedly installed inside the installation pipe 18, and guide pipes 23 fixedly installed at equal intervals at the bottom end of the installation pipe 18. The bottom end of the guide pipes 23 is fixedly connected to the top end of the water outlet pipe 24. When secondary dust removal is required, the air to be treated enters the cavity of the installation pipe 18 along a preset airflow path, forming a stable airflow field. At the same time, the water inlet pipe 20 delivers clean water to the diverter plate 19 according to a preset flow rate. 9. Through its internal diversion channels and flow equalization structure, the water source is evenly distributed to multiple nozzles 21 arranged circumferentially along the inner wall of the installation pipe 18. The nozzles 21 adopt a high-pressure atomization design to convert the diverted water source into fine water mist with a particle size of 5-50μm. The water mist forms a uniformly covered atomized dust removal area inside the installation pipe 18. When the air to be treated flows through the atomized dust removal area, the dust particles remaining in the air come into full contact with the atomized water droplets. Through inertial collision, Brownian motion and water film adsorption, the dust particles are efficiently captured, forming dust-laden water droplets. The dust-laden water droplets settle downwards under the action of gravity and fall onto the filter plate 22 inclined at the bottom of the installation pipe 18. Subsequently, the dust-laden water body gathers along the filter plate 22 to the guide pipe 23, and flows steadily into the outlet pipe 24 through the guide pipe 23, and is finally discharged outside the equipment.
[0024] The top of the filter plate 22 is provided with a guide groove arranged in a grid pattern. The filter plate 22 is provided with several perforations at equal intervals that are installed and cooperate with the guide pipe 23. The guide groove at the top of the filter plate 22 can guide the mixed liquid after dust removal in an orderly manner, guiding the mixed liquid to the perforations on the filter plate 22, and then flowing into the water outlet pipe 24 through the guide pipe 23.
[0025] The installation pipe 18 is symmetrically fixedly installed with partition seats 11 inside. The partition seats 11 can prevent the atomized water vapor sprayed by the nozzle 21 from being intercepted and restricted when the secondary dust removal mechanism 6 is performing dust reduction, and prevent the atomized water vapor from flowing randomly, thereby further improving the safety of the device during use.
