Description

Technical Field

[0001] The utility model relates to the technical field of gas transportation equipment, in particular to a gas transportation dehumidification and filtering device. Background Art

[0002] During the transportation process of traditional gas pipes, in winter, due to the large temperature difference between indoor and outdoor, natural gas is prone to condensation in the pipeline, and excessive accumulation is prone to freezing, causing blockage in the gas pipeline, greatly affecting the gas transmission efficiency. Therefore, it is necessary to dehumidify and filter the gas during the gas transportation process.

[0028] Embodiment 1

[0029] Combined with Figure 1-2, a partition 4 is provided in the box body 1, and the partition 4 separates a gas channel in the box body 1, and the air inlet pipe 2 and the air outlet pipe 3 are connected to the gas channel. A mounting plate 5 is symmetrically provided on the left side of the partition 4 in the box body 1, and a positioning component is provided on the side of the mounting plate 5 facing the partition 4, and the positioning component fixes the filter cotton, the positioning component is slidably connected to the partition 4, and a reset component is provided on the side of the mounting plate 5 facing the partition 4, and the reset component is connected to the partition 4, and the reset component includes a guide rod 6 and a spring 7, and the four corners of the mounting plate 5 are slidably connected with the guide rod 6, and the guide rod 6 is connected to the partition 4, and a spring 7 is provided between the partition 4 and the mounting plate 5, and the transmission assembly includes a transmission shaft 9 and a cam 10, and the left side of the mounting plate 5 in the box body 1 is rotatably connected with the transmission shaft 9, and a cam 10 is provided on the transmission shaft 9 at a position corresponding to the position of the mounting plate 5, and the cam 10 is set in the opposite direction, and the cam 10 is in contact with the mounting plate 5, and a hand wheel 11 is provided on the end of the transmission shaft 9 exposed from the box body 1.

[0030] In normal use, one positioning component is exposed in the gas channel, and the other positioning component is located outside the gas channel. The filter cotton fixed by the positioning component dehumidifies and filters the gas. When it is necessary to switch the exposed positioning component, the transmission shaft 9 is rotated, and the transmission shaft 9 drives the two cams 10 set in opposite directions to rotate. The cam 10 pressurizes the mounting plate 5, so that the positioning component that was not originally exposed in the gas channel is exposed in the gas channel. The other mounting plate 5 moves to the left under the elastic force of the spring 7 and the guiding action of the guide rod 6, so that the positioning component moves out of the gas channel, which is convenient for replacing the filter cotton. There is always filter cotton in the gas channel to dehumidify and filter the gas, and there is no need to shut down.

[0031] Combined with Figure 1 , 2 4. The positioning assembly includes a positioning plate 13 and a positioning groove 14. One end of the positioning plate 13 is connected to the mounting plate 5. The positioning plate 13 is provided with a positioning groove 14. One end of the positioning groove 14 is provided with a limiting plate 15. One side of the limiting plate 15 in the positioning groove 14 is provided with filter cotton. A flip cover 8 is hinged on the left side of the gas passage on the upper end face of the box body 1.

[0032] When replacing the filter cotton, the flip cover 8 is opened, and the filter cotton is pushed out from one end of the positioning groove 14 and the end where the limiting plate 15 is not provided, so that the filter cotton can be quickly replaced.

[0033] Embodiment 2

[0034] Combined with Figure 3 A positioning pin 12 is slidably connected to the hand wheel 11, and a positioning hole is provided on the back of the box body 1, and the positioning pin 12 is slidably connected to the positioning hole.

[0035] On the basis of Example 1, the transmission shaft 9 is rotated by the hand wheel 11. After the rotation, the angle of the hand wheel 11 is fixed by inserting the positioning pin 12 into the positioning hole on the box body 1, thereby fixing the angle of the transmission shaft 9 and ensuring that the positioning component is exposed in the gas channel.

[0036] The utility model and its implementation are described, and such description is not restrictive. The drawings are only one of the implementations of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and implementation example similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
