Description

Technical Field

[0001] This utility model relates to the field of gas supply, and in particular to a dehydration device for gas transmission. Background Technology

[0002] During long-distance gas transportation, gas with high water content often exhibits the following problems: water vapor and certain components of the gas form ice-like hydrates, clogging pipes and instruments; condensation accumulates in low-lying areas of the pipeline, reducing its gas transmission capacity and increasing power consumption. Therefore, it is necessary to effectively remove moisture from the gas before transportation. Common dehydration methods use adsorbents to absorb moisture from the gas, which requires frequent adsorbent replacement. Existing dehydration equipment involves cumbersome adsorbent replacement, has low efficiency, and is prone to leakage of residual gas from the transportation pipe during replacement. Utility Model Content

[0003] In view of the problems mentioned in the background art, the present invention provides a gas dehydration device for gas transportation that allows for quick replacement of the adsorption cylinder, improves working efficiency, and more effectively reduces gas leakage during adsorption cylinder replacement.

[0004] The technical solution is as follows: A dehydration device for gas transmission includes a housing, on which two conveying pipes are fixedly connected, and the two conveying pipes communicate with the interior of the housing. A circular hole is opened in the housing, and a turntable is rotatably connected inside the housing. The turntable has several through holes and a replacement mechanism is provided on the turntable. One of the conveying pipes is provided with a sealing mechanism. The replacement mechanism is used to replace the dehydration equipment, and the sealing mechanism is used to disconnect the communication between one of the conveying pipes and the housing when the replacement mechanism replaces the dehydration equipment, thereby reducing the leakage of residual gas in one of the conveying pipes.

[0005] As a further preferred embodiment, the replacement mechanism includes an adsorption cylinder, with each adsorption cylinder placed in a perforation in the turntable. Two rings are fixedly connected to each adsorption cylinder, and three inner adsorption rings are placed inside each adsorption cylinder. Sealing rings are fixedly connected to both ends of each adsorption cylinder. A motor is fixedly connected to the outer shell, and the motor output shaft is fixedly connected to the turntable.

[0006] As a further preferred embodiment, the sealing mechanism includes a one-way valve, one of the conveying pipes is rotatably connected to the one-way valve, a spur gear is fixedly connected to the one-way valve, a rack is slidably connected to one of the conveying pipes, a tension spring is connected between the rack and one of the conveying pipes, and a cam is fixedly connected to the motor output shaft.

[0007] As a further preferred embodiment, the rack meshes with the spur gear, and the rack is located below the spur gear.

[0008] As a further preferred embodiment, the cam has several protrusions on the side near the turntable, and these protrusions will sequentially contact the toothed rod.

[0009] The present invention has the following advantages: 1. The rotation of the motor output shaft will drive the turntable to rotate 60 degrees counterclockwise. The rotation of the turntable will drive the adsorption cylinder to be replaced with another unused adsorption cylinder, thus realizing the quick replacement of the adsorption cylinder and improving work efficiency.

[0010] 2. The rotation of the cam will strike the rack, causing the rack to move closer to the outer casing. The tension spring is stretched, and the rack will mesh with the spur gear during its movement, causing the spur gear to rotate 90 degrees. The spur gear will drive the one-way valve to rotate 90 degrees, thus isolating one of the air intake pipes from the outer casing. This can more effectively reduce gas leakage when the adsorption cylinder is replaced. Attached Figure Description

[0018] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0019] Example 1: A dehydration device for gas transmission, such as Figures 1-6 As shown, the device includes an outer shell 2, on which two conveying pipes 1 are fixedly connected. The two conveying pipes 1 are in communication with the interior of the outer shell 2. A circular hole is opened in the outer shell 2. A turntable 3 is rotatably connected inside the outer shell 2. The turntable 3 has several through holes and is equipped with a replacement mechanism. One of the conveying pipes 1 is equipped with a sealing mechanism. The replacement mechanism is used to replace the dehydration equipment. The sealing mechanism is used to disconnect the communication between one of the conveying pipes 1 and the outer shell 2 when the replacement mechanism replaces the dehydration equipment, thereby reducing the leakage of residual gas in one of the conveying pipes 1.

[0020] The replacement mechanism includes an adsorption cylinder 4, and each adsorption cylinder 4 is placed in a perforation in the turntable 3. Two rings 5 ​​are fixedly connected to each adsorption cylinder 4, three adsorption inner rings 6 are placed inside each adsorption cylinder 4, and sealing rings 7 are fixedly connected to both ends of each adsorption cylinder 4. A motor 8 is fixedly connected to the outer shell 2, and the output shaft of the motor 8 is fixedly connected to the turntable 3.

[0021] Initially, one of the adsorption cylinders 4 is connected to two conveying pipes 1. Gas is transported from one conveying pipe 1 to the other. During the transport process, the gas passes through one of the adsorption cylinders 4, causing it to dehydrate and adsorb water. After the adsorption cylinder 4 has been dehydrating the gas for a period of time, the operator stops feeding gas into one of the conveying pipes 1. Then, the operator starts the motor 8 and rotates it 60 degrees counterclockwise. The rotation of the output shaft of the motor 8 drives the turntable 3 to rotate 60 degrees counterclockwise. The rotation of the turntable 3 will replace the adsorption cylinder 4 with another unused adsorption cylinder 4, thus achieving the replacement of the adsorption cylinder 4. Then, the operator continues to feed gas into one of the conveying pipes 1 and uses a hooking device to hook the ring 5 on the adsorption cylinder 4 that has rotated to the opening of the outer casing 2, thereby removing the adsorption cylinder 4 and placing a new adsorption cylinder 4 in it. This achieves rapid replacement of the adsorption cylinder 4 and improves work efficiency.

[0022] Example 2: Based on Example 1, such as Figures 4-6As shown, the sealing mechanism includes a one-way valve 9, which is rotatably connected to one of the delivery pipes 1. A spur gear 10 is fixedly connected to the one-way valve 9, and a rack 11 is slidably connected to one of the delivery pipes 1. A tension spring 12 connects the rack 11 and one of the delivery pipes 1. A cam 13 is fixedly connected to the output shaft of the motor 8. When the cam 13 rotates, it will push against the rack 11, causing the rack 11 to move closer to the outer casing 2. During the movement of the rack 11, it will mesh with the spur gear 10, causing the spur gear 10 to rotate 90 degrees. The spur gear 10 will drive the one-way valve 9 to rotate 90 degrees. In this way, the one-way valve 9 will isolate one of the air-inlet delivery pipes 1 from the outer casing 2, which can more effectively reduce the leakage of gas when the adsorption cylinder 4 is replaced.

[0023] The rack 11 meshes with the spur gear 10, and the rack 11 is located below the spur gear 10.

[0024] The cam 13 has several protrusions on the side near the turntable 3, and these protrusions will contact the toothed rod 11 in sequence.

[0025] When the output shaft of motor 8 rotates counterclockwise, it drives the cam 13 to rotate. The rotation of cam 13 impacts the rack 11, causing it to move closer to the outer casing 2. The tension spring 12 is stretched, and the rack 11 meshes with the spur gear 10 during its movement, causing the spur gear 10 to rotate 90 degrees. The spur gear 10 then drives the one-way valve 9 to rotate 90 degrees, thus isolating one of the air intake pipes 1 from the outer casing 2. This reduces the leakage of residual gas in one of the air intake pipes 1. When the cam 13 and rack 11 disengage, the tension spring 12 drives the rack 11 to reset. The rack 11 moves in the opposite direction and meshes with the spur gear 10, causing the spur gear 10 to rotate in the opposite direction. The spur gear 10 then drives the one-way valve 9 to reset, so that the one-way valve 9 no longer isolates one of the air intake pipes 1 from the outer casing 2. This more effectively reduces gas leakage when the adsorption cylinder 4 is replaced.

Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
