Description

Technical Field

[0001] This utility model relates to the field of flame arrest and explosion relief technology, specifically a coal mine gas flame arrest, explosion relief and dehydration combined device. Background Technology

[0002] Coal mine gas refers to the naturally occurring combustible gas in coal mines, mainly composed of methane (CH4), and sometimes containing small amounts of carbon dioxide (CO2), nitrogen (N2), and other trace gases. The presence and management of coal mine gas are crucial for coal mine safety and environmental protection. Coal mine gas water seal flame arrestor and explosion-proof equipment is a safety device used in industries such as coal mining and chemical engineering. Its main purpose is to prevent gas explosions and prevent flames. However, current coal mine gas water seal flame arrestor and explosion-proof devices, although they can dehydrate coal mine gas to some extent, are not very effective in actual use. Additional dehydration equipment is required to further dehydrate the coal mine gas, which is inconvenient. Therefore, we propose a combined coal mine gas flame arrestor, explosion-proof, and dehydration device to solve the above problems. Utility Model Content

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 4As shown in the figure, an embodiment of this utility model proposes a coal mine gas flame arresting, explosion venting, and dehydration combined device, including a base plate 1. A flame arresting tank 2, an explosion venting tank 3, and a dehydration tank 4 are sequentially fixed to the top of the base plate 1. The outlet end of the flame arresting tank 2 is connected and fixed to the inlet end of the explosion venting tank 3 via a pipe. The outlet end of the explosion venting tank 3 is connected and fixed to the inlet end of the dehydration tank 4 via a pipe. A cyclone reversing pipe 5 is fixed inside the dehydration tank 4. A scraper assembly 6 for cleaning the inner wall of the dehydration tank 4 is installed inside the dehydration tank 4. A filter box 7 is fixed to the top of the base plate 1 via two supports. A frame 11 is fixed to the strip-shaped opening on the front of the filter box 7. A transparent plate 12 is fixed inside the frame 11, facilitating the worker's external inspection of the water level inside the filter box 7 for timely drainage. The bottom end of the dehydration tank 4 is connected and fixed to the top of the filter box 7. A filter screen 8 is fixed inside the filter box 7. A drain pipe 9 is connected and fixed to the drain hole of the filter screen 8. A filter is installed on the drain pipe 9. Equipped with valves, the filter box 7 has a plugging component 10 at its discharge port. Since the flame arrestor 2 and explosion relief tank 3 are existing technologies, their internal structure and working principle are not detailed here. When coal mine gas enters the dehydration tank 4 through the flame arrestor 2 and explosion relief tank 3, the gas enters the dehydration tank 4 under the action of the cyclone reversing pipe 5, thus achieving dehydration and dust removal. The treated gas is then discharged through the outlet pipe of the dehydration tank 4. Liquid and impurities remaining inside the dehydration tank 4 fall into the filter box 7, where they are separated by the filter screen 8. Finally, opening the valve on the drain pipe 9 discharges the liquid, and opening the plugging component 10 cleans the impurities filtered by the filter screen 8. Later, when cleaning the inner wall of the dehydration tank 4, simply activate the scraper component 6.

[0024] like Figure 2 and Figure 3As shown, in some embodiments, the scraper assembly 6 includes a mounting base 601 fixed inside the dehydration tank 4. A sealing cover 602 is fixed to the top of the mounting base 601. Metal heat dissipation fins 608 are fixed in a ring array on the surface of the sealing cover 602, which can play a role in auxiliary heat dissipation inside the sealing cover 602, so as to improve the protection of the motor 606. A rotating shaft 603 is rotatably connected to the top of the sealing cover 602 through a bearing. A rotating seat 604 is fixed to the surface of the rotating shaft 603. Three cleaning plates 605 are fixed on the rotating seat 604. Rubber strips 607 are fixed to one side wall of each cleaning plate 605. The other side of each rubber strip 607 is tightly pressed against the inner wall of the dehydration tank 4. The tight fit enhances the adhesion between the cleaning plate 605 and the inner wall of the dehydration tank 4, allowing for a more thorough cleaning of the inner wall. A motor 606 is fixed inside the sealing cover 602, with its output end fixedly connected to the bottom end of the rotating shaft 603. In use, starting the motor 606 drives the rotating shaft 603 to rotate, which in turn drives the rotating seat 604 to rotate. Finally, the rotating seat 604 rotates, causing the three cleaning plates 605 to rotate and clean the inner wall of the dehydration tank 4, thus scraping away impurities adhering to the inner wall. Furthermore, by installing the motor 606 inside the sealing cover 602, the motor 606 is protected.

[0025] like Figure 1 and Figure 4 As shown, in some embodiments, the sealing assembly 10 includes a mounting frame 1001 fixed at the impurity outlet of the filter box 7. An insert plate 1002 is fixed inside the slot of the mounting frame 1001. The insert plate 1002 is fixed to one side wall of the filter box 7 by bolts 1003. A rubber sleeve 1004 is fixed to the surface of the insert plate 1002. The outer surface of the rubber sleeve 1004 is in close contact with the inner surface of the mounting frame 1001. In use, the restriction on the insert plate 1002 can be released by loosening the bolts 1003. Then the insert plate 1002 can be separated from the mounting frame 1001. Subsequently, the impurities filtered by the filter screen 8 can be cleaned. After cleaning, the insert plate 1002 is inserted into the interior of the mounting frame 1001 and fixed. The rubber sleeve 1004 can enhance the sealing between the mounting frame 1001 and the insert plate 1002, preventing the dehydrated liquid from overflowing from the joint during filtration.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
