[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] This application provides a dosing cylinder for natural gas extraction, which can avoid the problem of reagents easily getting stuck in the dosing cylinder, realize the smooth operation of the reagent injection process, and improve the efficiency and benefits of natural gas extraction.

[0024] like Figure 1 As shown in the figure, this application embodiment provides a dosing cartridge 100 for natural gas extraction. The dosing cartridge 100 includes a cartridge body 10 and a guiding device 20. The cartridge body 10 has a connecting end and a dosing end disposed opposite each other along its length. The guiding device 20 is sleeved within the cartridge body 10. The guiding device 20 has a guiding channel extending through its length. Along its length, the guiding device 20 has a first end and a second end opposite each other. The first end is connected to the connecting end, and the second end is connected to the dosing end. The length direction of the cartridge body 10 is parallel to the length direction of the guiding device 20.

[0025] It should be noted that the guiding device 20 can be a guiding cylinder or multiple guiding plates spaced circumferentially around the dosing cartridge body 10, with the multiple guiding plates together forming a guiding channel. It is understood that the cross-sectional shape of the guiding device 20 in the length direction can be circular, rectangular, or other shapes, specifically determined according to the agent being dispensed, as long as the gap between the guiding channel and the agent to be dispensed is not too large. Since the guiding device 20 is located inside the dosing cartridge body 10, the length of the guiding device 20 is approximately equal to or greater than the length of the dosing cartridge body 10.

[0026] The dosing cartridge body 10 has a connecting end and a dosing end opposite each other along its length. The connecting end is used to connect to the gas-producing tree. When it is necessary to add pesticide to the dosing cartridge body 10, it needs to be added from the dosing end. Then, under the guidance of the guiding device 20, the pesticide falls from the dosing end of the dosing cartridge body 10 to the connecting end. It can be understood that the guiding device 20 and the dosing cartridge body 10 can be fixedly connected to the dosing cartridge 100 by welding, or they can be rotatably connected to the dosing cartridge 100 by a connector.

[0027] According to the embodiments of this application, a dosing cylinder 100 for natural gas extraction is provided with a guide device 20 inside the dosing cylinder 100. When it is necessary to inject chemicals into a natural gas well through the dosing cylinder 100, the chemicals are injected into the guide channel of the guide device 20. Since the gap between the chemicals and the guide channel is smaller than the gap between the chemicals and the dosing cylinder 100, the chemicals are less likely to tilt in the guide channel, and there is less chance of misalignment between the chemicals, which would cause the chemicals to get stuck. This ensures that the injected chemicals can fall smoothly in the guide channel of the guide device 20 under the action of gravity, so as to complete the injection of chemicals into the natural gas well and improve the efficiency and benefits of natural gas extraction.

[0028] like Figure 2-3 As shown, in some embodiments, the dosing cartridge 100 further includes a connecting assembly 30. The first end and the connecting end, and the second end and the dosing end are respectively connected to each other through the connecting assembly 30, wherein the guide device 20 rotates relative to the dosing cartridge body 10 about its own length direction as the axis of rotation.

[0029] In this embodiment, the guide device 20 is provided with connecting components 30 at the first and second ends to connect with the dosing cylinder body 10. At the same time, the guide device 20 can rotate relative to the dosing cylinder body 10 with the axis of rotation of the dosing cylinder body 10 through the connecting components 30, so that the agent in the guide channel can fall more smoothly, and the agent is prevented from getting stuck in the guide channel of the guide device 20, thereby improving the efficiency of natural gas extraction.

[0030] like Figure 2-3 As shown, in some embodiments, the connecting component 30 includes a first sliding groove 31 and a first slider 32 that slide against each other. The first sliding groove 31 is disposed on the inner side wall of the dosing cartridge body 10, and the first slider 32 is disposed on the outer side wall of the guide device 20. The first sliding groove 31 is annular and coaxially disposed with the dosing cartridge body 10.

[0031] It should be noted that in this embodiment, the first chute 31 is disposed on the inner wall of the dosing cylinder 100, and the first slider 32 is disposed on the outer wall of the guide device 20; alternatively, the first chute 31 can be disposed on the outer wall of the guide device 20, and the first slider 32 can be disposed on the inner wall of the dosing cylinder 100.

[0032] In this embodiment, the first sliding groove 31 provided on the inner side wall of the dosing cartridge body 10 and the first slider 32 provided on the outer side wall of the guide device 20 are slidably engaged, so that the guide device 20 can rotate relative to the dosing cartridge body 10 with the axis of the dosing cartridge body 10 as the axis of rotation, thereby preventing the medicine in the guide device 20 from getting stuck in the guide channel.

[0033] like Figure 2-3 As shown, in some embodiments, multiple balls are spaced apart between the contact surfaces of the first groove 31 and the first slider 32 along the length of the dosing cartridge 100. This transforms the sliding connection between the first groove 31 and the first slider 32 into a rolling connection, reducing friction during rotation and allowing the guide device 20 to rotate better relative to the dosing cartridge body 10.

[0034] In some embodiments, the connecting assembly 30 includes a connecting disk. The surface of the connecting disk is provided with an annular second sliding groove and a first through hole. The dosing end and the connecting end of the dosing cartridge body 10 are both provided with a second slider and a third slider at intervals. The second slider and the third slider are both slidably engaged with the second sliding groove. The guide device 20 is fixedly connected to the connecting disk, and the surface of the disk is provided with a first through hole at the position corresponding to the guide channel.

[0035] In this embodiment, the connecting assembly 30 includes a connecting plate, and the guide device 20 and the dosing cartridge body 10 are connected by the connecting plate. The guide plate has a second sliding groove on its surface. A second slider and a third slider on the dosing end and connecting end of the dosing cartridge body 10 respectively slide in cooperation with the second sliding groove. The guide device 20 is fixedly connected to the guide plate. When the guide device 20 rotates, the second slider and the third slider on the dosing end and connecting end of the dosing cartridge body 10 rotate within the second sliding groove along the annular groove.

[0036] like Figure 4 As shown, in some embodiments, the dosing cartridge 100 further includes a transmission assembly 40. The transmission assembly 40 includes a driving wheel 41 and a driven wheel 42 that are in contact with and drive each other. The driven wheel 42 is fixedly connected to the guide device 20, and the axial direction of the driven wheel 42 is parallel to the length direction of the guide device 20.

[0037] It should be noted that the driven gear 42 can be a disc-shaped gear with a central hole. The disc-shaped gear is sleeved on the outer wall of the guide device 20 through the central hole and is fixedly connected to the guide device 20. The driving gear 41 is meshed with the driven gear 42.

[0038] In this embodiment, the driven wheel 42 is coaxially arranged with the guide device 20. The rotation of the driving wheel 41 drives the driven wheel 42 to rotate, so that the driven wheel 42 drives the guide device 20 to rotate relative to the dosing cartridge body 10 within the dosing cartridge body 10.

[0039] like Figure 4 As shown, according to any of the foregoing embodiments of this application, the dosing cylinder 100 further includes a driving member 50, which is connected to the drive wheel 41 and drives the drive wheel 41 to rotate. The driving member 50 may be a drive motor, an operating handle, etc. By energizing the drive motor or rotating the operating handle, the driving member 50 drives the drive wheel 41 to rotate, which in turn drives the driven wheel 42 to rotate, and the driven wheel 42 in turn drives the guide device 20 to rotate.

[0040] like Figure 1-4 As shown, according to any of the foregoing embodiments of this application, the guiding device 20 includes a guiding sleeve, the dosing cylinder body 10 and the guiding sleeve are coaxially arranged, and the cross-sectional shape of the dosing cylinder body 10 and the guiding sleeve in the length direction of the dosing cylinder 100 is circular.

[0041] According to any of the foregoing embodiments of this application, the side wall of the guide sleeve is provided with a plurality of second through holes at intervals to reduce the weight of the guide sleeve and reduce production costs.

[0042] This application also provides a natural gas collection device, which includes the dosing cylinder 100 of any of the above embodiments of this application.

[0043] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict.
