Description

Technical Field

[0001] This utility model relates to a sample preparation device, and more particularly to a sample preparation device for preparing cross-linked polyethylene insulation material samples in the laboratory. Background Technology

[0002] Cross-linked polyethylene insulation is a high-performance insulating material that forms a three-dimensional network structure by cross-linking polyethylene molecular chains through physical or chemical methods. It combines the excellent insulation properties of polyethylene with the improved heat resistance, mechanical strength, and resistance to environmental stress cracking after cross-linking, and is widely used in fields such as wires and cables and power transmission.

[0003] When preparing cross-linked polyethylene insulation samples in the laboratory, due to the small number of samples used in the experiment, the semi-finished particles with pre-added solid additives are usually placed in a bottle and heated in a hot air box. After heating to a certain temperature, the required liquid additives are added to the bottle. Then, the bottle is manually shaken at certain intervals to allow the added liquid additives to be slowly absorbed into the semi-finished product. This process is not only time-consuming and labor-intensive, but also makes it difficult to maintain a constant temperature, resulting in poor absorption of the liquid additives. In addition, it also easily leads to poor uniformity of shaking, further resulting in poor absorption of the liquid additives. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a sample preparation device for preparing cross-linked polyethylene insulation material samples in the laboratory. It is not only time-saving and labor-saving, but also easy to ensure constant temperature and has good shaking uniformity.

[0034] Example 1

[0035] like Figures 1-3This embodiment provides a sample preparation device for preparing cross-linked polyethylene insulation material samples in the laboratory, including: a hot air box 1, including a box body 11 and a cover 12 that are movably connected to each other; a hot air source connected to the hot air box 1; a roller 2, including a cylinder body 20, a first side cover 21 and a second side cover 22, the first side cover 21 and the second side cover 22 being threadedly connected to both ends of the cylinder body 20, and both the first side cover 21 and the second side cover 22 being detachably and rotatably connected to the box body 11; and a driver 3, the drive shaft of the driver 3 being detachably driven connected to the first side cover 21.

[0036] Specifically, firstly, solid additives and semi-finished particles are placed inside drum 2, and then drum 2 is placed inside hot air box 1. Drum 2 is heated to a certain temperature by a hot air source. Next, liquid additives are placed inside drum 2, and then the driver 3 is turned on at certain intervals. The drive shaft of driver 3 drives the first side cover 21, the cylinder 20, and the second side cover 22 to rotate in sequence, which facilitates the absorption of liquid additives into the semi-finished particles. The driver 3 drives the shaking instead of manually, which not only saves time and effort, but also ensures good shaking uniformity, thereby improving the absorption effect of liquid additives. Since drum 2 and the solid additives, semi-finished particles, and liquid additives inside it are all located inside hot air box 1 during rotation, it is easy to maintain a constant temperature, thereby improving the absorption effect of liquid additives.

[0037] The hot air source can be electric heating, combustion, etc.; the driver 3 can be stepper, servo, etc.

[0038] Furthermore, such as Figure 1 It also includes a first rotating shaft 23 and a second rotating shaft 24 that are detachably and rotatably connected to the housing 11. The first rotating shaft 23 is connected to the first side cover 21, the second rotating shaft 24 is connected to the second side cover 22, and the first rotating shaft 23 is detachably driven connected to the drive shaft of the driver 3.

[0039] Specifically, the first rotating shaft 23 and the second rotating shaft 24 facilitate the rotation of the roller 2 within the housing 11.

[0040] Furthermore, such as Figure 2 It also includes: a first slot and a second slot 112 respectively provided on both sides of the housing 11; a first insert that is detachably engaged with the first slot; and a second insert 42 that is detachably engaged with the second slot 112; wherein, the first rotating shaft 23 is detachably rotatable in the first slot, and the second rotating shaft 24 is detachably rotatable in the second slot 112.

[0041] Specifically, the first slot and the second slot 112 facilitate the detachable connection between the roller 2 and the housing 11; the first insert and the second insert 42 facilitate the restriction of the rotational position of the first rotating shaft 23 and the second rotating shaft 24, thereby ensuring the smooth rotation of the roller 2 within the housing 11.

[0042] Furthermore, such as Figure 1 It also includes: a first gear 51 connected to the drive shaft of the driver 3; and a second gear 52 connected to the first rotating shaft 23, wherein the second gear 52 and the first gear 51 mesh.

[0043] Specifically, the drive shaft of the driver 3 sequentially drives the first gear 51, the second gear 52, the first rotating shaft 23, the first side cover 21, and the cylinder 20 to rotate.

[0044] Furthermore, such as Figure 1 It also includes several stirring blades 6, all of which are connected inside the cylinder 20.

[0045] Specifically, several stirring plates 6 facilitate the increase of the stirring performance of the drum 2, thereby facilitating the absorption of liquid additives.

[0046] Furthermore, such as Figures 1-2 It also includes: an air inlet 113 located on the housing 11; and an air outlet 121 located on the cover 12; wherein both the air inlet 113 and the air outlet 121 are connected to a hot air source.

[0047] Specifically, the hot air source is provided through the air inlet 113 and the air outlet 121 to ensure a continuous supply of hot air to the hot air box 1, thereby ensuring a constant temperature.

[0048] Furthermore, such as Figure 1 It also includes bracket 7, driver 3 and bracket 7 connection.

[0049] Specifically, bracket 7 is used to support driver 3.

[0050] Furthermore, such as Figure 1 The box body 11 and the cover body 12 are rotatably connected.

[0051] Specifically, the rotating connection facilitates the closing and unfolding performance of the box 11 and the cover 12, and occupies little space after unfolding.

[0052] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
