Description

Technical Field

[0001] This utility model relates to the field of natural gas processing, specifically a stirring device for natural gas processing. Background Technology

[0002] Natural gas processing is the process of purifying raw natural gas extracted from gas fields (containing various impurities) into clean energy that meets transportation standards or industrial / civilian requirements. Its core objectives are to remove impurities (such as water, hydrogen sulfide, carbon dioxide, heavy hydrocarbons, etc.), increase the calorific value of natural gas, recover valuable by-products (such as liquefied petroleum gas, natural gasoline, etc.), and meet environmental and safety standards.

[0003] Chinese Patent No. CN202222901231.2 discloses a mixing device for natural gas processing, including a mixing chamber containing an synergist. An air inlet pipe is fixedly installed on one side of the mixing chamber, and a control valve is installed inside the air inlet pipe. One end of the air inlet pipe extends into the interior of the mixing chamber and is fixedly connected to a nozzle. A servo motor is fixedly installed on the other side of the mixing chamber, and a stirring rod is fixedly connected to the output end of the servo motor. One end of the stirring rod extends into the interior of the mixing chamber and multiple stirring blades are fixedly connected to its surface.

[0004] As can be seen from the above, turning on the servo motor can drive the stirring rod to rotate, which in turn drives the stirring blades on the surface of the stirring rod to rotate, thus agitating the enhancer and making the natural gas and enhancer mix more evenly. However, this solution also has the following shortcomings: the inner wall of the mixing chamber is prone to adhering with crystals or impurities of the treatment agent. When the crystals or impurities of the treatment agent accumulate to a certain extent, they affect the rotation of the stirring blades, which in turn affects the treatment quality of the natural gas treatment process; the delivery of the treatment agent relies heavily on manual adjustment of valves, resulting in large flow control errors and unstable natural gas treatment effects.

[0005] Therefore, a stirring device for natural gas processing is proposed to address the above problems. Utility Model Content

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 scope of protection of the present utility model.

[0024] Please see Figures 1-5 As shown, a stirring device for natural gas processing includes a main body 1. A stirring assembly 2 is provided on one side of the main body 1. The stirring assembly 2 includes a movable cleaning component 3 and a metering conveying component 4. The movable cleaning component 3 includes a base 21 installed on one side of the main body 1. A stirring chamber 22 is fixedly installed on the top of the base 21. A gas conveying channel 23 is fixedly installed in the stirring chamber 22. A chamber cover 24 is provided on one side of the stirring chamber 22. A sealing ring 27 is fixedly installed on the side of the chamber cover 24 and is movably installed with the stirring chamber 22 through the sealing ring 27. A first stepper motor 25 is provided on the other side of the chamber cover 24. A stirring blade 26 is fixedly installed at the output end of the first stepper motor 25.

[0025] During operation, natural gas enters the mixing chamber 22 through the gas transmission channel 23. At the same time, the second stepper motor 41 of the metering conveyor 4 drives the spiral auger blades 42 to rotate, metering the treatment agent in the treatment agent chamber 38 into the mixing chamber 22. The first stepper motor 25 drives the stirring blades 26 to rotate, fully mixing the natural gas and treatment agent.

[0026] Furthermore, the main body 1 includes an input pipe 11, one end of which is fixedly installed at the input end of the pump 12, and the other end of which is fixedly installed at the top of the mixing chamber 22. An output pipe 13 is fixedly installed at the output end of the pump 12, and the other end of which is fixedly installed at the top of the gas storage chamber 14.

[0027] During operation, the pump 12 extracts and pressurizes the natural gas that has been stirred through the mixing process through the input pipe 11, and then delivers it to the gas storage silo 14 through the output pipe 13 for storage.

[0028] Furthermore, the movable cleaning component 3 also includes a connecting rod 28, which is fixedly installed on the top of the base 21. A servo motor 29 is fixedly installed on one side of the connecting rod 28. A ball screw 31 is fixedly installed at the output end of the servo motor 29. A ball nut 32 is threaded through and connected to the ball screw 31. Fixing rods 36 are fixedly installed on both sides of the ball nut 32. The other ends of the two fixing rods 36 are fixedly installed in the inner cavity of the movable sleeve 33.

[0029] During operation, when the mixing chamber 22 needs to be cleaned, the servo motor 29 starts, driving the ball screw 31 to rotate. The ball nut 32 moves along the ball screw 31, causing the fixed rod 36 and the movable sleeve 33 to move synchronously, thereby opening the chamber cover 24 and exposing the interior of the mixing chamber 22 for easy cleaning.

[0030] Furthermore, the connecting rod 28 has a movable groove 37, and a fixed rod 36 is slidably installed through the movable groove 37. Several slide rails 35 are fixedly installed on the connecting rod 28, and pulleys 34 are slidably installed on the several slide rails 35 respectively.

[0031] During operation, the fixed rod 36 slides in the movable groove 37, which serves as a guide to ensure the smooth movement of the movable sleeve 33. The pulley 34 slides on the slide rail 35 to reduce the friction when the movable sleeve 33 moves, making the opening and closing of the cover 24 smoother.

[0032] Furthermore, a connecting seat 30 is fixedly installed on one side of the movable sleeve 33, a first stepper motor 25 is fixedly installed on one side of the connecting seat 30, and the other side of the connecting seat 30 is fixedly installed on the outer surface of the cover 24.

[0033] During operation, the connecting seat 30 fixes the first stepper motor 25 and the bin cover 24 in place, so that the first stepper motor 25 can drive the stirring blade 26 to perform stirring or cleaning operations in the stirring bin 22.

[0034] Furthermore, the quantitative conveying component 4 includes a treatment agent chamber 38, a conveying channel 39 is fixedly installed on one side of the treatment agent chamber 38, a second stepper motor 41 is fixedly installed on one side of the conveying channel 39, a spiral auger blade 42 is fixedly installed at the output end of the second stepper motor 41, the spiral auger blade 42 is rotatably installed in the inner cavity of the conveying channel 39, and one end of the conveying channel 39 is fixedly installed on one side of the mixing chamber 22.

[0035] During operation, according to the requirements of the natural gas processing technology, the speed of the second stepper motor 41 is set by the control system. The second stepper motor 41 drives the spiral auger blades 42 to rotate in the conveying channel 39, conveying the processing agent in the processing agent tank 38 to the mixing tank 22 according to the set flow rate, so as to realize the quantitative and precise delivery of the processing agent.

[0036] Working principle: Natural gas enters the mixing chamber 22 through the gas transmission channel 23. Simultaneously, according to the processing requirements, the speed of the second stepper motor 41 is set by the control system, driving the auger blades 42 to quantitatively transport the processing agent from the processing agent chamber 38 to the mixing chamber 22 via the conveying channel 39. The first stepper motor 25 drives the stirring blades 26 to rotate at a speed of 100-300 r / min, thoroughly mixing the natural gas and processing agent. The mixing time can be set to 5-15 min according to process requirements. After mixing is complete, the pump 12 starts... Natural gas in the mixing chamber 22 is extracted and pressurized through the input pipe 11 and then transported to the gas storage chamber 14 through the output pipe 13. When the mixing chamber 22 needs to be cleaned, the servo motor 29 is started, driving the ball screw 31 to rotate. The ball nut 32 drives the fixed rod 36 and the movable sleeve 33 to move along the slide rail 35, so that the chamber cover 24 opens automatically, exposing the interior of the mixing chamber 22 for easy cleaning. The first stepper motor 25 can be used to control the mixing blade 26 to reverse and scrape off impurities from the chamber wall. After cleaning, the chamber cover 24 closes automatically, and the sealing ring 27 re-forms a seal.
