Description

Technical Field

[0001] This utility model relates to the field of pneumatic sample delivery technology, and in particular to a sample cylinder and a pneumatic sample delivery assembly for pneumatic sample delivery. Background Technology

[0002] In industries such as metallurgy, pneumatic sample delivery methods are used to transport items. Specifically, high-pressure gas is injected into a delivery pipeline, and the object to be transported is placed in a sample cylinder. The sample cylinder moves along the delivery pipeline under the propulsion of the high-pressure gas until it reaches the target location.

[0003] To prevent the sample cylinder from getting stuck in the delivery pipe, the outer wall of the sample cylinder is not tightly fitted to the inner wall of the delivery pipe; that is, a gap is left between the outer wall of the sample cylinder and the inner wall of the delivery pipe, allowing some high-pressure gas to enter. As the high-pressure gas propels the sample cylinder forward, it will bounce up and down due to the airflow and its own weight, causing friction and collision with the delivery pipe.

[0004] The shortcomings of existing pneumatic sample delivery devices include: friction and collision can damage the sample cylinder, and even damage the items inside the sample cylinder, especially sample cylinders made of metal, which are more severely affected by friction and collision, and will significantly shorten the service life of the sample cylinder; friction and collision can change the spatial posture of the sample cylinder in the delivery pipeline. When the sample cylinder is tilted relative to the direction of travel, it may get stuck in the delivery pipeline, affecting normal delivery; when the sample cylinder is damaged and deformed due to friction and collision, some deformed structures on the sample cylinder may get stuck in the delivery pipeline, causing the delivery pipeline to be blocked, resulting in a poor user experience. Utility Model Content

[0005] The purpose of this invention is to propose a sample cylinder and a pneumatic sample delivery assembly for pneumatic sample delivery, which solves the problem that existing sample cylinders are prone to friction and collision with the delivery pipeline, resulting in a better user experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A sample cylinder for pneumatic sample delivery includes a detachably connected cylinder body and a cylinder cover. The cylinder cover can seal the open end of the cylinder body. An air passage is formed on the outer circumferential surface of the cylinder body. The air passage is spiral-shaped relative to the axis of the cylinder body. On the radial cross section of the cylinder body, a support surface is formed between two adjacent air passages. The air passage forms a groove-shaped structure relative to the support surface.

[0008] In one preferred embodiment, the air passage includes a bottom wall and two side walls, the two side walls being respectively connected to opposite sides of the bottom wall, the bottom wall being parallel to the outer circumferential surface of the cylinder body, and the side walls being perpendicular to the outer circumferential surface of the cylinder body.

[0009] In one preferred embodiment, the width S of the bottom wall is 5mm ± 0.5mm, and the height H of the side wall is 2.5mm ± 0.25mm.

[0010] In one preferred embodiment, at least two air passages are formed on the outer peripheral surface of the cylinder body, and all the air passages have the same shape.

[0011] In one preferred embodiment, fifteen air passages are evenly distributed on the radial cross-section of the cylinder body.

[0012] In one preferred embodiment, the width L of the support surface on the radial cross-section of the cylinder body is 10mm ± 1mm.

[0013] In one preferred embodiment, the included angle α between the air passage and the axis of the cylinder body is 60°±5°.

[0014] In one preferred embodiment, the cylinder body further includes a main body portion and a conical shoulder, the large-diameter end of the shoulder being connected to the main body portion, the small-diameter end of the shoulder being connected to the opening end, and the diameter of the opening end being smaller than the diameter of the main body portion.

[0015] In one preferred embodiment, the diameter of the cylinder cover is smaller than the diameter of the main body, the air passage is only provided on the main body, and the outer surfaces of the cylinder shoulder and the cylinder cover are both smooth.

[0016] On the other hand, the present invention adopts the following technical solution:

[0017] The pneumatic sample delivery assembly includes a delivery pipe and a sample cylinder for pneumatic sample delivery, the sample cylinder being located within the delivery pipe.

[0018] The sample cylinder disclosed in this utility model has a spiral air passage formed on its outer circumferential surface. When the sample cylinder moves in the delivery pipe, the high-pressure gas will cause the sample cylinder to be in a high-speed spin state, thereby generating centripetal force. The movement of the sample cylinder is more stable, avoiding friction and collision between the sample cylinder and the delivery pipe, ensuring the safety of the sample cylinder and the contents inside, and extending the service life of the sample cylinder. It also prevents the delivery pipe from being stuck or blocked by the sample cylinder, ensuring that the items can be delivered to the destination smoothly, resulting in a better user experience.

[0019] The pneumatic sample delivery assembly disclosed in this utility model includes the sample cylinder for pneumatic sample delivery mentioned above. The sample cylinder moves more smoothly in the delivery pipeline, avoiding friction and collision with the delivery pipeline, extending the service life of the sample cylinder, and making the transport of items smoother.

[0031] This embodiment discloses a pneumatic sample delivery component for transporting items from one location to another in industries such as metallurgy. It is particularly suitable for automated rapid analysis systems and offers high item transport efficiency.

[0032] The pneumatic sample delivery assembly mainly consists of a delivery pipe and a sample cylinder, with the sample cylinder located within the delivery pipe. For example... Figure 1 and Figure 2 As shown, the sample tube includes a detachably connected tube body 1 and a tube cover 2. The tube cover 2 can seal the open end 11 of the tube body 1. The tube body 1 and the tube cover 2 together form an inner cavity 16, and the item to be conveyed is placed in the inner cavity 16.

[0033] An air passage 12 is formed on the outer circumferential surface of the cylinder body 1, and the air passage 12 is spiral-shaped relative to the axis of the cylinder body 1. On the radial section of the cylinder body 1, a support surface 13 is formed between two adjacent air passages 12, and the air passage 12 forms a groove-shaped structure relative to the support surface 13.

[0034] The spiral air passage 12 makes the shape of the main body 1 of the sample tube similar to that of a bullet or shell. When the sample tube moves in the delivery pipe, high-pressure gas flows through the air passage 12, causing the sample tube to be in a high-speed spinning state, thereby generating centripetal force. The movement of the sample tube is more stable, avoiding friction and collision between the sample tube and the delivery pipe, ensuring the safety of the sample tube and the items in the inner cavity 16, and extending the service life of the sample tube. It also prevents the delivery pipe from being stuck or blocked by the sample tube, ensuring that the items can be delivered smoothly to the destination, resulting in a better user experience.

[0035] The specific implementation of the air passage 12 and the support surface 13 is not limited. It can be that a spiral groove is milled into the outer surface of the cylinder body 1, forming the air passage 12, and the outer surface of the original cylinder body 1 between two adjacent air passages 12 forms the support surface 13; alternatively, a raised ridge is welded to the outer surface of the cylinder body 1, forming the support surface 13, and the outer surface of the original cylinder body 1 between two adjacent support surfaces 13 forms the air passage 12. The air passage 12 and support surface 13 formed in both of these ways serve the same purpose: to keep the sample cylinder in a high-speed spinning state when the high-pressure airflow passes through, resulting in more stable sample cylinder movement.

[0036] The specific shape of the air passage 12 is not limited, as long as it allows high-pressure airflow to pass through. In this embodiment, for example... Figure 2 and Figure 3 As shown, the air passage 12 includes a bottom wall 121 and two side walls 122. The two side walls 122 are respectively connected to the opposite sides of the bottom wall 121. The bottom wall 121 is parallel to the outer peripheral surface of the cylinder body 1, and the side walls 122 are perpendicular to the outer peripheral surface of the cylinder body 1.

[0037] Along the direction perpendicular to the extension of the air passage 12, the cross-section of the air passage 12 is approximately rectangular, allowing for smoother flow of high-pressure gas. The flow direction of the high-pressure gas forms an angle with the extension direction of the air passage 12. As the high-pressure gas flows, it impacts one side wall 122 of the air passage 12 (the side wall 122 on the windward side). The high-pressure gas exerts pressure on this side wall 122, causing the sample cylinder to rotate around its own axis and generate centripetal force.

[0038] The shape and size of the original sample tube do not need to be changed when setting the air passage 12 and the support surface 13, and the specific size of the air passage 12 is not limited. In this embodiment, the height of the sample tube is still 208mm, the diameter of the sample tube is still 72mm, the width S of the bottom wall 121 is 5mm±0.5mm, preferably 4.5mm, 4.7mm, 4.9mm, 5mm, 5.1mm, 5.3mm and 5.5mm; the height H of the side wall 122 is 2.5mm±0.25mm, preferably 2.25mm, 2.35mm, 2.45mm, 2.5mm, 2.55mm, 2.65mm and 2.75mm. The air passage 12 and the support surface 13 can be formed by slightly modifying the existing sample tube, which is convenient to process and has low modification cost.

[0039] To increase the rotational speed of the sample cylinder, at least two air passages 12 are formed on the outer circumferential surface of the cylinder body 1, and all air passages 12 have the same shape. When high-pressure gas flows through, it can simultaneously impact the sidewalls 122 of at least two air passages 12. The sum of the pressure values ​​acting on all sidewalls 122 is significantly greater than the pressure value on a single sidewall 122, thereby enabling the sample cylinder to rotate around its own axis more quickly.

[0040] In this embodiment, fifteen air passages 12 are evenly distributed on the radial cross section of the cylinder body 1. While ensuring that the sample cylinder rotates fast enough, the number of air passages 12 is minimized to reduce the processing difficulty, minimize the reduction in the strength of the cylinder body 1, and improve the service life of the sample cylinder.

[0041] To prevent deformation of the sidewall 122 of the air passage 12 due to the high-pressure airflow after long-term use, the distance between two adjacent air passages 12 needs to be appropriately increased. In this embodiment, the width L of the support surface 13 on the radial cross-section of the cylinder body 1 is 10mm ± 1mm, preferably 9mm, 9.3mm, 9.5mm, 9.8mm, 10mm, 10.3mm, 10.5mm, 10.8mm, and 11mm. That is, the distance between two adjacent air passages 12 is about 10mm, resulting in high strength and strong impact resistance.

[0042] If the angle α between the air passage 12 and the axis of the cylinder body 1 is too small, the impact force along the circumference of the cylinder body 1 when the high-pressure gas impacts the side wall 122 of the air passage 12 will be small, resulting in a slow rotation speed of the sample cylinder. If the angle α between the air passage 12 and the axis of the cylinder body 1 is too large, the side wall 122 of the air passage 12 will essentially block the flow path of the high-pressure gas, leading to excessive wind resistance and high energy consumption. In this embodiment, the angle α between the air passage 12 and the axis of the cylinder body 1 is 60°±5°, preferably 55°, 58°, 60°, 62°, and 65°, balancing the rotation speed of the sample cylinder and the wind resistance of the high-pressure gas, resulting in a better user experience.

[0043] Based on the above structure, the main body 1 includes a main body 15, a shoulder 14, and an open end 11 connected in sequence. The shoulder 14 is conical. The larger diameter end of the shoulder 14 connects to the main body 15, and the smaller diameter end connects to the open end 11. The diameter of the open end 11 is smaller than the diameter of the main body 15. The smaller opening end 11 and the cap 2 are easier to insert into the conveying pipe, making it more convenient to use. When the conical shoulder 14 touches the edge of the conveying pipe opening, it automatically adjusts its position, ensuring that the entire shoulder 14 can enter the conveying pipe more smoothly. The main body 15 is connected to the shoulder 14. After the shoulder 14 is fully inside the conveying pipe, the main body 15 can smoothly follow, improving the assembly speed of the sample cylinder and providing a better user experience.

[0044] The diameter of most areas on the cylinder cover 2, the opening end 11, and the cylinder shoulder 14 is smaller than the diameter of the main body 15. Most areas on the cylinder cover 2, the opening end 11, and the cylinder shoulder 14 are far from the inner wall of the conveying pipeline. High-pressure gas can pass smoothly through most areas on the cylinder cover 2, the opening end 11, and the cylinder shoulder 14. Therefore, opening the air passage 12 at the above-mentioned locations has limited effect.

[0045] In this embodiment, the air passage 12 is only provided on the main body 15, and the outer surfaces of the cylinder shoulder 14 and the cylinder cover 2 are smooth, which reduces the processing difficulty and manufacturing cost.

[0046] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
