TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of material pneumatic transportation, in particular to a warehouse pump pressure relief exhaust pipeline device and system. BACKGROUND
[0002] With the progress of science and technology, the smelting process of blast furnace slag is continuously optimized, its production capacity is also continuously improved through potential tapping, and the reducing agent used is gradually increased. In the production process, a large amount of solid reducing agent is transported by a pneumatic conveying system, transported to the weighing bin at the top of the carbonization furnace by a warehouse pump, and finally added into the furnace by metering for reduction smelting. The working process principle of the warehouse pump is usually as follows: when the control system detects that the reducing agent powder bin is working normally, the reducing agent exceeds the low material level, and the system has a starting condition, the system starts the discharging system, and then the inlet dome valve is opened, the material falls into the warehouse pump by gravity, the exhaust valve is opened during the material falling process, and the warehouse pump exhaust ensures the smoothness of the material falling. When the high material level of the warehouse pump is triggered, the system closes the exhaust valve, a certain time delay is provided, the inlet dome valve is closed and sealed, and after a period of time, the pressurized inlet valve is opened, and the material enters the conveying pipeline to start conveying. When the pressure of the warehouse pump decreases to the set value, the conveying gas is closed, the exhaust valve is opened, and the next material falling cycle is prepared.
[0003] In the related art, the exhaust pipeline device connected with the warehouse pump usually has a bend and an elbow. Due to the frequent operation of the warehouse pump for conveying, the exhaust valve at the top of the warehouse pump is opened, the dust-containing gas passes through the pipeline and the elbow, enters the top of the top bin, and before entering the bin, due to the limitation of the installation arrangement structure, the pipeline is usually turned and folded to the top of the bin, and is connected to the bin at a suitable position to play a role of exhaust pressure equalization. The flow rate of the dust-containing gas in the small pipe diameter is large, and the dust intensifies the abrasion of the pipeline and the elbow, especially the elbow at the top of the bin, and the service life is generally not more than 10 days, which seriously affects the material conveying and also brings a series of safety and environmental protection problems. The high failure rate of the exhaust device seriously restricts the continuous economic production of enterprises, increases the consumption of spare parts, and also brings huge operation safety risks.
[0004] Therefore, how to effectively complete the warehouse pump pressure relief exhaust for a long time has become a problem to be solved. UTILITY MODEL CONTENT

[0030] likeFigure 2 As shown, this utility model discloses a pressure relief and exhaust pipeline device for a silo pump, comprising: a sealed box 11, a pressure relief pipe 12, and an ash discharge pipe 13, wherein,
[0031] The sealed box 11 has a first opening and a second opening at the bottom. The pressure relief part 121 of the pressure relief pipe 12 enters the interior of the sealed box 11 through the first opening. One end of the ash discharge pipe 13 is connected to the second opening. The sealed box 11, the pressure relief pipe 12, and the ash discharge pipe 13 together constitute a pressure relief chamber.
[0032] Specifically, the sealed chamber 11 is a rectangular pressure relief chamber, in which all surfaces are sealed and welded. The bottom surface serves as the connection surface between the pressure relief pipe 12 and the ash discharge pipe 13. The bottom surface of the sealed chamber 11 has a first opening and a second opening. The first opening is connected to the pressure relief pipe 12, and the second opening is connected to the ash discharge pipe 13. Dust and gas enter the pressure relief chamber through the pressure relief section 121 of the pressure relief pipe 12. Since the pressure relief chamber is a sealed chamber, excess gas and dust are discharged from the pressure relief chamber through the ash discharge pipe 13, thus achieving the function of exhaust pressure equalization.
[0033] Specifically, the diameter of the pressure relief pipe 12 is usually selected as DN80 or DN100. This embodiment does not make a specific limitation on this, and it can be set according to the actual working conditions.
[0034] Specifically, the diameter of the ash discharge pipe 13 is usually selected as DN150-DN200. This embodiment does not make a specific limitation on this, and it can be set according to the actual working conditions.
[0035] Through the above technical solution, this disclosure provides a pressure relief and exhaust pipe and system for a silo pump. The device includes: a sealed box, a pressure relief pipe, and an ash discharge pipe. The sealed box has a first opening and a second opening at its bottom. The pressure relief section of the pressure relief pipe enters the sealed box through the first opening. One end of the ash discharge pipe is connected to the second opening. The sealed box, the pressure relief pipe, and the ash discharge pipe together constitute a pressure relief chamber. This invention uses a sealed box, a pressure relief pipe, and an ash discharge pipe to form a pressure relief chamber. During this process, gas and dust are discharged from the sealed box through the pressure relief pipe. The discharged gas and dust are then discharged through the ash discharge pipe within the pressure relief chamber, completing the removal of excess gas and the collection of dust, thus achieving pressure equalization during exhaust. Furthermore, because the pressure relief pipe reduces the impact of dust erosion on the exhaust pipe, it extends the service life of the exhaust pipe device.
[0036] In some alternative embodiments, the pressure relief section 121 has at least one pressure relief hole for discharging gas and dust from the pressure relief pipe 12.
[0037] Specifically, the pressure relief section 121 has at least one pressure relief hole. When the reducing agent dust is at a low level and the material needs to be discharged from the silo, the silo pump pressurizes the reducing agent dust and carries it by gas through the pressure relief pipe 12. The gas and dust carried in the pressure relief pipe 12 enter the pressure relief chamber through the pressure relief hole of the pressure relief section 121. Since the pressure relief chamber is a closed chamber, excess gas and dust are discharged from the pressure relief chamber through the ash discharge pipe 13, which plays the role of exhaust pressure equalization.
[0038] In some alternative embodiments, the pressure relief hole is located on the side of the pressure relief section 121.
[0039] Specifically, such as Figure 1 As shown, when the pressure relief hole is located on the side of the pressure relief section 121, the pressure relief hole is an opening on the side of the pressure relief pipe 12, and the diameter of the pressure relief hole is usually selected as ¢20mm. Furthermore, when there are multiple pressure relief holes, they are opened around the pressure relief section 121, typically with a center-to-center spacing of about 50mm, and the opening area is selected to be 300mm in length. This embodiment does not impose specific limitations on this, and it can be set according to actual working conditions.
[0040] In some alternative embodiments, the pressure relief hole is located at the top of the pressure relief section 121.
[0041] Specifically, when the pressure relief hole is located at the top of the pressure relief section 121, the pressure relief hole is an opening at the top of the pressure relief pipe 12, and the diameter of the pressure relief hole is usually selected as ¢20mm. When there are multiple pressure relief holes, the center distance between the holes is usually about 40mm. This embodiment does not make a specific limitation on this, and it can be set according to the actual working conditions.
[0042] In some alternative embodiments, the ash discharge pipe 13 has a preset angle with the bottom of the sealed box 11, and the ash discharge pipe 13 is used to discharge the gas and dust in the sealed box 11.
[0043] Specifically, the preset angle between the ash discharge pipe 13 and the bottom of the beehive 11 is used to facilitate the rapid discharge of dust. The preset angle can be 30°, 60° or other degrees. This embodiment does not limit this in any specific way and can be set according to the actual working conditions.
[0044] In some alternative embodiments, the pressure relief chamber further includes a first sealing element for sealing the gap between the pressure relief pipe 12 and the first opening.
[0045] Specifically, the first sealing element is used to seal the gap between the pressure relief pipe 12 and the first opening to ensure the airtightness of the pressure relief chamber.
[0046] In some alternative embodiments, the pressure relief chamber further includes a second sealing element for sealing the gap between the ash discharge pipe 13 and the second opening.
[0047] Specifically, the second sealing element is used to seal the gap between the ash discharge pipe 13 and the second opening to ensure the airtightness of the pressure relief chamber.
[0048] In some alternative embodiments, the pressure relief pipe 12 is a straight-through pipe.
[0049] Specifically, the pressure relief pipe 12 is a straight-through pipe, which avoids the bends and elbows in the exhaust pipe, thereby reducing the impact of dust erosion on the exhaust pipe and extending the service life of the exhaust pipe device.
[0050] In some alternative embodiments, the ash discharge pipe 13 is a straight-through pipe.
[0051] Specifically, the ash discharge pipe 13 is a straight pipe, which avoids the bends and elbows in the exhaust pipe, thereby reducing the impact of dust scouring on the exhaust pipe and extending the service life of the exhaust pipe device.
[0052] like Figure 1 As shown, this utility model discloses a silo pump pressure relief and exhaust pipeline system, including: a silo 2, a silo pump 3, and a silo pump pressure relief and exhaust pipeline device as described in the foregoing embodiments, wherein,
[0053] The hopper 2 is connected to the other end of the ash discharge pipe 13, the hopper 2 is connected to the inlet of the hopper pump 3, and the outlet of the hopper pump 3 is connected to the pressure relief pipe 12.
[0054] Specifically, when the control system detects that the reducing agent powder silo is working normally, the reducing agent level exceeds the low level, and the system meets the start-up conditions, it starts the system discharge system. Immediately, the inlet dome valve opens, and the material falls into the silo pump 3 by its own weight. During the discharge process, the exhaust valve opens, and the reducing agent dust in the silo pump 3 enters the sealed box 11 along with the gas through the pressure relief pipe 12 and the pressure relief part 121. After the gas is released, the silo pump 3 continuously depressurizes until it reaches normal pressure. The excess gas and dust enter the silo 2 through the ash discharge pipe 13, completing the material transportation process. In this process, since the pressure relief pipe 12 and the ash discharge pipe 13 are straight-through pipes, the impact of dust scouring on the exhaust pipe is reduced, thereby extending the service life of the exhaust pipe device.
[0055] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this disclosure.
