Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to a medical degreased gauze drying device. Background Technology

[0002] Medical degreased gauze is an essential item used in hospitals and in daily life. Due to its special use, the quality requirements for medical degreased gauze are becoming increasingly stringent. The key to its production lies in ensuring the degreasing rate, whiteness, and strength. Degreasing primarily removes cotton wax, pectin, and grease from cotton fibers, while bleaching mainly increases the whiteness of the gauze. Currently, medical degreased gauze is mainly produced through processes such as alkaline boiling, chlorine bleaching, acid washing, and neutral water washing. A drying process is also involved in the production of medical degreased gauze.

[0003] A search of the China Patent Network (authorization announcement number CN 206709545 U) revealed a drying device for medical degreased gauze. The device rotates the drying drum, which improves the drying effect of the medical degreased gauze inside the drum during use. It can also be flipped and rotated, making the drying of the drum more uniform and effective.

[0004] However, the accumulation of medical degreased gauze inside the drying drum causes the drying progress of the inner and outer layers of the gauze to be asynchronous. Furthermore, because the drying drum contains a loosely woven cotton fabric with a distinct mesh, the outermost layer of degreased gauze may burn due to excessive temperature, resulting in a waste of the degreased gauze's cost. Therefore, a medical degreased gauze drying device is proposed. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a medical degreased gauze drying device, which can ensure a uniform temperature during the drying of medical degreased gauze and avoid the situation where the medical degreased gauze is burned due to high temperature.

[0006] This utility model also proposes a medical degreased gauze drying device, comprising: a base plate, an outer frame fixed to the top of the base plate, a top cover rotatably provided on the top of the outer frame, multiple sets of driven cylinders assembled inside the outer frame, positioning shafts rotatably provided on both sides of the multiple sets of driven cylinders near the left and right inner walls of the outer frame, an exhaust fan assembled on the outer side of the outer frame at the top of the base plate, an air supply pipe extending to the rear surface of the outer frame at the output end of the exhaust fan, and a branch pipe connected to the multiple sets of driven cylinders on the outer wall of the air supply pipe;

[0007] The driven cylinder has multiple sets of air outlets on its curved outer wall. An inner cylinder fixed to the inner wall of the base plate is fitted inside the driven cylinder. A heating rod for heating air is installed inside the inner cylinder. A spiral blade fixed to the inner wall of the inner cylinder is attached to the outer wall of the heating rod.

[0008] According to some embodiments of the present invention, the input end of the induced draft fan is connected to an air inlet pipe, and a filter screen is installed at the end of the air inlet pipe.

[0009] According to some embodiments of this utility model, the top of the outer frame is reserved with a notch near the left and right edges, and the highest tangent point of the positioning shaft is aligned with the notch.

[0010] According to some embodiments of the present invention, the inner wall of the outer frame is fixed with two sets of guide plates at the top of the base plate, and a collection trough is provided at the top of the base plate at the gap between the two sets of guide plates. The front surface of the base plate is provided with holes for discharging water from the inside of the collection trough.

[0011] According to some embodiments of this utility model, the driven cylinder has base rings fixed at both ends and rotatably connected to the inner wall of the outer frame. One end of the inner cylinder is connected to the branch pipe via a flared head, and the other end of the inner cylinder has multiple sets of arc openings near the curved outer wall.

[0012] According to some embodiments of this utility model, the spiral blades and heating rods form a spiral channel inside the inner cylinder.

[0013] According to some embodiments of this utility model, the inner diameter of the branch pipe is larger than the inner wall diameter of the air outlet.

[0014] The embodiments of this utility model have at least the following beneficial effects:

[0015] This utility model discloses a medical degreased gauze drying device. Multiple driven cylinders cause the medical degreased gauze to move in a zigzag trajectory within the outer frame, resulting in a longer heating and drying time. Meanwhile, the air entering the inner cylinder is fully heated through the spiral channel and then blown onto the gauze in multiple directions through the air outlet, resulting in high-quality drying. Since the driven cylinders are constantly rotating, their contact time with the gauze is limited, preventing the gauze from burning due to high temperatures. Attached Figure Description

[0028] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0029] like Figures 1 to 6 A medical degreased gauze drying device is shown, comprising: a base plate 100, an outer frame 110 fixed to the top of the base plate 100, a top cover 120 rotatably provided on the top of the outer frame 110, a plurality of driven cylinders 150 assembled inside the outer frame 110, positioning shafts 160 rotatably provided on both sides of the plurality of driven cylinders 150 near the left and right inner walls of the outer frame 110, an exhaust fan 130 assembled on the outer side of the outer frame 110 at the top of the base plate 100, an air supply pipe 140 extending to the rear surface of the outer frame 110 provided at the output end of the exhaust fan 130, and a branch pipe 141 connected to the plurality of driven cylinders 150 on the outer wall of the air supply pipe 140.

[0030] Multiple sets of air outlets 151 are provided on the curved outer wall of the driven cylinder 150. An inner cylinder 170 fixed to the inner wall of the base plate 100 is provided inside the driven cylinder 150. A heating rod 180 for heating air is installed inside the inner cylinder 170. A spiral blade 190 fixed to the inner wall of the inner cylinder 170 is added to the outer wall of the heating rod 180.

[0031] Both ends of the driven cylinder 150 are fixed with base rings 152 that are rotatably connected to the inner wall of the outer frame 110. One end of the inner cylinder 170 is connected to the branch pipe 141 via the horn head 172. The other end of the inner cylinder 170 is provided with multiple sets of arc openings 171 near the curved outer wall.

[0032] The spiral blade 190 and the heating rod 180 form a spiral channel inside the inner cylinder 170.

[0033] The medical degreased gauze is distributed in a folded pattern on the outer wall of multiple driven cylinders 150. When the dried medical degreased gauze is rolled up externally, the multiple driven cylinders 150 will roll, thereby achieving the purpose of slowly conveying the medical degreased gauze. At the same time, the blower 130 draws the external air into the air supply pipe 140, and then delivers it to the inside of the inner cylinder 170 one by one through multiple branch pipes 141. The spiral blades 190 cause the air to flow around the curved outer wall of the heating rod 180, making the path of the air through the outer wall of the heating rod 180 longer, and achieving the effect of heating the air by the heating rod 180 for a longer time, so that the air is fully heated. Finally, the air is discharged from the outside of the inner cylinder 170 through the arc opening 171. Heating air is located in the space between the outer wall of the inner cylinder 170 and the driven cylinder 150, and is finally discharged to the outside through the air outlet 151. Since the driven cylinder 150 rotates with the movement of the medical degreasing gauze, the multiple air outlets 151 on the outer wall of the driven cylinder 150 blow hot air onto the medical degreasing gauze from different directions. This avoids blind spots in the drying of the medical degreasing gauze. The area and time of contact between the medical degreasing gauze and the heat source are limited, so the medical degreasing gauze will not be burned due to high temperature. In addition, the multiple sets of driven cylinders 150 make the path of the medical degreasing gauze within the outer frame 110 longer. Combined with the relatively sealed outer frame 110, this makes the drying of the medical degreasing gauze more uniform and thorough.

[0034] Please refer to this carefully. Figure 1 and Figure 3 The input end of the induced draft fan 130 is connected to an air inlet pipe, and a filter screen is installed at the end of the air inlet pipe.

[0035] The air drawn in by the blower 130 is filtered to prevent particles from damaging the blower 130, and at the same time to protect the gauze being dried, so that the dried medical degreased gauze is of high quality.

[0036] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The top of the outer frame 110 has a notch 113 near the left and right edges. The highest point of the positioning shaft 160 is aligned with the notch 113. The corner of the notch 113 has an arc chamfer.

[0037] This ensures that the medical degreased gauze entering and exiting the outer frame 110 is not scratched or worn by the groove 113, and that the production qualification rate of the medical degreased gauze reaches the standard value.

[0038] Please refer to this carefully. Figure 3 The inner wall of the outer frame 110 is fixed with two sets of guide plates 111 at the top of the base plate 100. A collection trough 112 is provided at the top of the base plate 100 at the gap between the two sets of guide plates 111. The front surface of the base plate 100 is provided with holes for discharging water from the collection trough 112.

[0039] Water droplets dripping from medical degreased gauze are collected and guided until they flow into the central collection trough 112, where they can be quickly discharged to the outside of the device, preventing them from accumulating inside the outer frame 110.

[0040] Please refer to this carefully. Figure 2 and Figure 5 The inner diameter of the branch pipe 141 is larger than the inner wall diameter of the vent 151.

[0041] This causes the air discharge speed inside the driven cylinder 150 to be less than the input speed, which allows the air inside to be heated for a longer time, thus achieving a better drying effect on the gauze.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
