Description

Technical Field

[0001] The utility model relates to the technical field of gas discharge devices, and particularly relates to an automatic pressure regulating and gas discharging device for a gas main pipe. Background Technique

[0002] The gas main pipe, also known as the gas drainage pipe, is a pipeline system specifically used for collecting and processing the gas generated in coal mines; the gas main pipe is mainly used for safely discharging gas, preventing gas explosion accidents, recovering surplus coal resources, supporting and strengthening, and serving as a pulverized coal pipeline, etc.

[0003] The Chinese patent discloses a low-concentration gas safety transportation device (authorization publication number CN 219912685 U). Compared with the prior art, this patented technology adopts an electric emergency gas discharging device, adjusts the gas discharging amount by controlling a special electric regulating valve for gas to make the remaining gas transportation amount match the combustion amount of the gas generator set, and discharges all the gas by controlling the electric butterfly valve during the shutdown and overhaul of the gas power plant; however, the gas also has certain utilization value. When the gas is extracted and transported, this device does not have the function of purification, which is inconvenient for the subsequent use of the gas in the later stage; and both are manually adjusted and discharged, with low safety.

[0004] Therefore, those skilled in the art provide an automatic pressure regulating and gas discharging device for a gas main pipe to solve the problems raised in the above background technique. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides an automatic pressure regulating and gas discharging device for a gas main pipe, including a gas pipe; a slag leakage port is opened at the lower part of the inner wall on the left side of the gas pipe, and a filter screen is installed on the right side of the slag leakage port; a slag storage tank is installed under the slag leakage port; a pressure regulating and gas discharging mechanism is installed on the upper side in the middle of the gas pipe; a steam-water separator is installed on the right side of the gas pipe; and a water circulation cooling mechanism is installed at the bottom of the steam-water separator.

[0006] Preferably: sliding grooves are opened on the left and right sides of the upper part of the bottom of the slag storage tank, sliders are installed in the sliding grooves, a moving plate is installed between the two sliders, and a handle is installed on the front side of the moving plate; a visible window is installed on the front side of the slag storage tank. After the gas pipe is used, the slag storage amount inside the slag storage tank is observed through the visible window to judge whether to clean it; when the slag storage tank needs to be cleaned, the moving plate is pulled out from the bottom of the slag storage tank by pulling the handle, and then the cleaning can be carried out; in this way, the filter screen is used to filter the extracted gas, which can ensure the purity of the gas, facilitate subsequent use, and also avoid the impurities carried by the gas from blocking the gas pipe and affecting the use of the gas pipe.

[0007] Preferably, the pressure regulating and discharging mechanism includes an exhaust pipe installed on the upper side of the gas pipe. A breather pipe is installed in the middle of the exhaust pipe, and the breather pipe is slightly larger than the exhaust pipe. Vent holes are provided around the breather pipe to facilitate the discharge of gas. A spring is installed on the inner wall of the top of the exhaust pipe, and a baffle is installed at the bottom of the spring. When the gas pipe transports gas, if the internal pressure is too high and higher than the elastic pressure of the spring, the gas will move upward through the exhaust pipe of the pressure regulating and discharging mechanism, thereby squeezing the baffle. The baffle moves upward, and the excess gas will be discharged through the vent holes of the breather pipe, thereby achieving the purpose of pressure regulating and discharging. There is no need for manual pressure regulating and discharging, which greatly improves safety.

[0008] Preferably, the water circulation cooling mechanism includes a drain pipe, the top end of which is installed at the bottom of the steam-water separator. A water tank is fixedly installed at the bottom of the drain pipe. An inlet is installed at the front of the top of the water tank, and the inlet is generally sealed and will only be opened when water needs to be added to the water tank. A water suction pipe is installed on the left side of the water tank, and the other end of the water suction pipe is installed with a water pump. A water delivery pipe is installed on one side of the water pump, and the other side of the water delivery pipe is connected to a cooling pipe sleeve. There are two cooling pipe sleeves that are symmetrically arranged left and right. A connecting pipe is installed between the two cooling pipe sleeves to ensure that the two cooling pipe sleeves are connected. The water pump can draw cold water from the water tank through the water suction pipe, reach the cooling pipe sleeve on the right side through the water delivery pipe, and then ensure that the cooling pipe sleeve on the left side is filled with cold water through the connecting pipe. The cold water in the cooling pipe sleeve can cool the surface of the gas pipe, avoid the surface temperature of the gas pipe from being too high, and thus affect the internal gas.

[0009] Preferably, support feet are installed at the bottoms of the two cooling pipe sleeves, and anti-slip pads are provided at the bottoms of the support feet, and the number of anti-slip pads is the same as that of the support feet.

[0010] The technical effects and advantages of the present utility model:

When the slag storage tank needs to be cleaned, the moving plate can be pulled out from the bottom of the slag storage tank by pulling the handle, and then the cleaning can be carried out. In this way, the filter screen is used to filter the extracted gas, which can ensure the purity of the gas, facilitate subsequent use, and also avoid impurities carried by the gas from blocking the gas pipe and affecting the use of the gas pipe.

[0012] 2. In the present utility model, when the gas pipe transports gas, if the internal pressure is too high and higher than the elastic pressure of the spring, the gas will move upward through the exhaust pipe of the pressure regulating and discharging mechanism, thereby squeezing the baffle. The baffle moves upward, and the excess gas will be discharged through the vent holes of the breather pipe, thereby achieving the purpose of pressure regulating and discharging. There is no need for manual pressure regulating and discharging, which greatly improves safety.

Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes. Embodiment

[0022] Please refer to Figures 1 to 6 In this embodiment, an automatic pressure regulating and discharging device for a gas main pipe is provided, including a gas pipe 1, and the gas pipe 1 is used to transport gas. A slag leakage port 14 is opened at the lower part of the inner wall on the left side of the gas pipe 1, and a filter screen 15 is installed on the right side of the slag leakage port 14. The filter screen 15 is used to filter the extracted gas, and the filtered impurities fall into the slag storage tank 16 through the slag leakage port 14. The slag storage tank 16 is installed on the lower side of the slag leakage port 14. A pressure regulating and discharging mechanism is installed on the upper side in the middle of the gas pipe 1. When the internal pressure of the gas pipe 1 is too high, the pressure regulating and discharging mechanism can be automatically opened for discharging, avoiding explosion caused by too high internal pressure and resulting in safety accidents. A steam-water separator 5 is installed on the right side of the gas pipe 1. The steam-water separator 5 is used to extract the moisture inside the gas, reduce the humidity of the gas, facilitate transportation, and the separated gas continues to be transported through the gas pipe 1. A water circulation cooling mechanism is installed at the bottom of the steam-water separator 5, which is used to collect the separated water vapor and reuse it, facilitating the cooling of the surface of the gas pipe 1;

[0023] On the upper left and right sides of the bottom of the slag storage tank 16, sliding grooves 20 are opened. Sliding blocks 19 are installed in the sliding grooves 20. A moving plate 18 is installed between the two sliding blocks 19, and a handle 21 is installed on the front side of the moving plate 18. A visual window 17 is installed on the front side of the slag storage tank 16. After the gas pipe 1 is used, the slag storage amount inside the slag storage tank 16 is observed through the visual window 17 to judge whether to clean it. When the slag storage tank 16 needs to be cleaned, the moving plate 18 is pulled out from the bottom of the slag storage tank 16 by pulling the handle 21, and then cleaning can be carried out. In this way, the filter screen 15 is used to filter the extracted gas, which can ensure the purity of the gas, facilitate subsequent use, and also avoid the impurities carried by the gas from blocking the gas pipe 1 and affecting the use of the gas pipe 1;

[0024] The pressure regulating and discharging mechanism includes an exhaust pipe 2. The exhaust pipe 2 is installed on the upper side of the gas pipe 1, and a vent pipe 6 is installed in the middle of the exhaust pipe 2. The vent pipe 6 is slightly larger than the exhaust pipe 2. Vent holes are opened around the vent pipe 6 to facilitate the discharge of gas. A spring 22 is installed on the inner wall of the top of the exhaust pipe 2, and a baffle 23 is installed at the bottom of the spring 22. When the gas pipe 1 transports gas, if the internal pressure is too high and higher than the elastic pressure of the spring 22, the gas will move upward through the exhaust pipe 2 of the pressure regulating and discharging mechanism, thereby squeezing the baffle 23. The baffle 23 moves upward, and the excess gas will be discharged through the vent holes of the vent pipe 6, thereby achieving the purpose of pressure regulating and discharging, without the need for manual pressure regulating and discharging, greatly improving safety;

[0025] The water cycle cooling mechanism includes a drain pipe 8, and the top end of the drain pipe 8 is installed at the bottom of the steam-water separator 5; a water tank 9 is fixedly installed at the bottom of the drain pipe 8, and a water inlet 10 is installed at the front of the top of the water tank 9. The water inlet 10 is generally sealed and will only be opened when water needs to be added to the water tank 9; a water extraction pipe 11 is installed on the left side of the water tank 9, the other end of the water extraction pipe 11 is installed with a water pump 12, a water delivery pipe 13 is installed on one side of the water pump 12, and the other side of the water delivery pipe 13 is connected to a cooling pipe sleeve 7; there are two symmetrically arranged cooling pipe sleeves 7 on the left and right, and a connecting pipe 24 is installed between the two cooling pipe sleeves 7. Through the connecting pipe 24, the two cooling pipe sleeves 7 can be ensured to communicate with each other; the water pump 12 can extract cold water from the water tank 9 through the water extraction pipe 11, reach the cooling pipe sleeve 7 on the right side after passing through the water delivery pipe 13, and then ensure that the cooling pipe sleeve 7 on the left side is filled with cold water through the connecting pipe 24; the cold water contained in the cooling pipe sleeve 7 can cool the surface of the gas pipe 1, avoiding the surface temperature of the gas pipe 1 being too high, which will affect the internal gas.

[0026] Support feet 3 are installed at the bottoms of the two cooling pipe sleeves 7, and anti-slip pads 4 are provided at the bottoms of the support feet 3. The number of the anti-slip pads 4 is the same as that of the support feet 3; the anti-slip pads 4 can increase the friction between the support feet 3 and the ground, making it not easy to tip over, and increasing safety and stability.

[0027] The working principle of the present utility model is as follows: When transporting gas, first, the extracted gas is filtered by the filter net 15, and the filtered impurities fall into the slag storage box 16 through the slag discharge port 14, and then the filtered gas is transported to the right; if the internal air pressure is too high and higher than the elastic pressure of the spring 22, the gas will move upward through the exhaust pipe 2 of the pressure regulating and discharging mechanism, thereby squeezing the baffle 23. The baffle 23 moves upward, and the excess gas will be discharged through the ventilation holes of the ventilation pipe 6, thereby achieving the purpose of pressure regulating and discharging; then, the moisture inside the gas is extracted by the steam-water separator 5 to reduce the humidity of the gas, which is convenient for transportation. The separated gas continues to be transported through the gas pipe 1; finally, if the surface temperature of the gas pipe 1 is too high, the water pump 12 can extract cold water from the water tank 9 through the water extraction pipe 11, reach the cooling pipe sleeve 7 on the right side after passing through the water delivery pipe 13, and then ensure that the cooling pipe sleeve 7 on the left side is filled with cold water through the connecting pipe 24; the cold water contained in the cooling pipe sleeve 7 can cool the surface of the gas pipe 1.

[0028] The steam-water separator 5 is a prior art, and its wiring method and the wiring methods of the internal processor and other electrical components are also prior arts. Therefore, its working principle will not be described in this text.
