Abstract
Description
Technical Field
[0001] A rotary drying device for a plasma tray belongs to the field of medical equipment technology. Background Technology
[0002] With the improvement of medical facilities and the enhancement of people's health awareness in China, the demand for blood products is constantly increasing. According to the process in the blood products workshop, plasma trays need to be directly stored in cold storage after cleaning and drying. Therefore, the entire system has high requirements for the dryness or residual water level of the plasma trays to avoid the trays sticking together after stacking. Due to the limitations of the tray structure, many water droplets that cannot be dried remain inside and on the sides of the trays after cleaning.
[0003] In existing technologies, the most common method is to use compressed gas to purge and dry the plasma tray, as described in Chinese invention patent application number 202411333491.1, filed on September 24, 2024, entitled "A Plasma Tray Cleaning and Tilting Device". However, in practical implementation, this method has the following drawbacks: when using compressed gas for purging, residual water cannot be effectively removed, and there is a significant risk of freezing and adhesion.

[0018] Figure 1 This is a schematic diagram of the rotary drying device for plasma trays.
[0019] Figures 2-3 This is a schematic diagram of the operation of the rotary drying device for the plasma tray.
[0020] The components include: 1. Rotary motor; 2. Coupling; 3. Main frame; 4. Rotary sleeve; 5. Drive roller; 6. Limiting plate; 7. Limiting frame; 8. Limiting cylinder; 9. Roller frame; 10.

[0021] Figures 1-3 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-3 The present invention will be further described below.
[0022] like Figure 1 As shown, a rotary drying device for a plasma tray (hereinafter referred to as the rotary drying device) includes a main frame 3, which is a rectangular frame structure, and base feet 16 are respectively provided at the four corners of the bottom of the main frame 3.
[0023] A rotary motor 1 is fixed at the top of the main frame 3, with its motor shaft pointing vertically downwards. The motor shaft of the rotary motor 1 extends vertically through the top surface of the main frame 3 and into its interior. A rotating sleeve 4 is positioned above and inside the main frame 3. The motor shaft of the rotary motor 1 is connected to a rotating shaft fixed to the top of the rotating sleeve 4 via a coupling 2. Therefore, when the rotary motor 1 rotates, it drives the rotating sleeve 4 to rotate within the main frame 3.
[0024] A roller frame 9 is horizontally arranged in the middle of the main frame 3. Several drive rollers 5 are horizontally arranged within the roller frame 9, all of which are parallel and at the same height. The arrangement direction of all drive rollers 5 is the same as that of the plasma tray 17 (see...). Figures 2-3 The plasma tray 17 is positioned in the direction of transport. A limiting mechanism is installed at the end of the transport direction to limit the plasma tray 17. In this rotary drying apparatus, all drive rollers 5 are independently rotating electric rollers.
[0025] Of all the drive rollers 5 fixed by the roller frame 9, the two ends of the plasma tray 17 in the conveying direction are long rollers, and the middle part in the conveying direction of the plasma tray 17 is a short roller, thus forming a space in the middle of the roller frame 9. A detection switch, such as a limit switch or an infrared switch, is installed in this space to detect the conveying position of the plasma tray 17. When the plasma tray 17 is conveyed to its position by the drive rollers 5, the detection switch is triggered, at which point all the drive rollers 5 stop rotating. Controlling the drive mechanism (such as the motor and the drive rollers 5 in this rotary drying device) through detection switches is common knowledge and practice in the field, and its specific circuit structure will not be described in detail here.
[0026] The aforementioned limiting mechanism is located at the edge of the central space of the roller frame 9. The limiting mechanism includes a limiting frame 7 fixed within the main frame 3, and a limiting cylinder 8 fixed at the lower part of the limiting frame 7. The piston rod of the limiting cylinder 8 passes through the limiting frame 7 and extends to the upper part of the limiting frame 7. The limiting cylinder 8 is vertically positioned, and a limiting plate 6 is fixed to the end of its piston rod. In this rotary drying apparatus, the limiting plate 6 in the limiting mechanism is used to block the plasma tray 17. When the plasma tray 17 moves to the limiting plate 6, it stops moving forward due to the blockage of the limiting plate 6. At this time, the aforementioned detection switch detects the plasma tray 17 to control the drive roller 5 to stop rotating.
[0027] A lifting cylinder 13 is installed at the lower part of the roller frame 9, and the lifting cylinder 13 is fixed inside the main frame 3. The lifting cylinder 13 is located at the center of the middle space of the roller frame 9. The piston rod of the lifting cylinder 13 is vertically upward, and a lifting seat 12 is horizontally fixed at the top of the piston rod of the lifting cylinder 13. Multiple guide shafts 14 are arranged around the lower surface of the lifting seat 12, and the guide shafts 14 pass through the corresponding frames inside the main frame 3.
[0028] A rotating seat 11 is rotatably mounted at the center of the upper surface of the lifting seat 12, and a rotating disk 10 is coaxially fixed on the surface of the rotating seat 11. When the piston rod of the lifting cylinder 13 is in the retracted state, the upper surface of the rotating disk 10 is flush with or lower than the upper edge of the drive roller 5.
[0029] The specific working process and working principle are as follows:
[0030] like Figures 2-3 As shown, the plasma tray 17 to be dried is placed on one side of the main frame 3 and positioned on the upper surface of the roller frame 9. At this time, the drive rollers 5 on the surface of the roller frame 9 rotate and drive the plasma tray 17 to move into the main frame 3. When the plasma tray 17 moves to the limiting mechanism, the limiting plate 6 inside the limiting mechanism blocks the plasma tray 17. At the same time, the detection switch installed in the roller frame 9 detects that the plasma tray 17 has been delivered to the correct position and (via the controller) controls all the drive rollers 5 to stop rotating.
[0031] After the plasma tray 17 is delivered to its position, it is directly above the rotating disk 10. The piston rod of the lifting cylinder 13 outputs, sequentially driving the lifting seat 12, the rotating seat 11, and the rotating disk 10 to rise, thus achieving the lifting of the plasma tray 17. When the piston rod of the lifting cylinder 13 outputs to its position, the plasma tray 17 is fully inserted into the rotating sleeve 4.
[0032] The rotary motor 1 rotates, driving the rotating sleeve 4 to rotate as well. The inner contour of the rotating sleeve 4 matches the outer contour of the plasma tray 17, so when the rotating sleeve 4 rotates, it simultaneously drives the plasma tray 17 to rotate. Since the rotating seat 11 is rotatably connected to the lifting seat 12, when the plasma tray 17 rotates, the rotating seat 11 and the rotating disk 10 rotate simultaneously. The water in the plasma tray 17 is thrown out under the action of centrifugal force, thus achieving the rotation of the plasma tray 17. A collection tray 15 is also provided at the bottom of the main frame 3. Some of the water thrown out of the plasma tray 17 falls into the collection tray 15 and is discharged uniformly.
[0033] When the rotary motor 1 stops rotating after a predetermined time, the piston rod of the lifting cylinder 13 resets, causing the plasma tray 17 to descend. After the plasma tray 17 falls onto the surface of the drive roller 5, the rotary drying process of the plasma tray 17 is completed.
[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
