[0020] The following will describe the implementation of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Please refer to Figure 1 , Figure 1 It is a schematic diagram of a quantitative drying device for multiple groups of nylon raw materials according to an embodiment of the present utility model.

[0022] As shown in the figure, a multi-group quantitative drying device for nylon raw materials includes: a rotating cylinder 10, the rotating cylinder 10 has a heat source cylinder cavity 11 located in the center and passing through, and a drying working chamber 12 surrounded by the heat source cylinder cavity 11, the heat source cylinder cavity 11 and the drying working chamber 12 are separated by a stainless steel cylinder cover 13, and a plurality of drying through holes are arranged on the surface of the stainless steel cylinder cover 13; two groups of partition plates 20 are arranged in the drying working chamber 12 and spaced apart, and the partition plates 20 divide the drying working chamber into three sub-chambers, and the side walls of the rotating cylinder 10 have switch gates 30 corresponding to the sub-chambers respectively, and the switch gates 30 are used to open the sub-chambers; a heat source pipe is installed and connected to one end of the rotating cylinder 10 through a sealing bearing 40, and the heat source pipe is connected to a hot air blower for inputting hot air into the heat source cylinder cavity 11; a pressure relief hole 50 is arranged at the other end of the rotating cylinder 10, and a protective film 60 is provided on the surface of the pressure relief hole 50.

[0023] In one embodiment of the present invention, the rotating cylinder 10 is driven to rotate by a sprocket, and a stainless steel cylinder cover 13 is installed inside. The stainless steel cylinder cover 13 divides the rotating cylinder 10 into a central heat source cylinder cavity 11 and an outer drying working cavity 12, wherein the drying working cavity 12 is used to fill nylon raw materials.

[0024] The two partition plates 20 divide the drying working chamber into three sub-chambers at the front, middle and rear, and the side walls of the rotating cylinder 10 are respectively installed with switch gates 30 corresponding to each sub-chamber. The switch gates 30 are used to fill nylon raw materials by opening and closing the sealed sub-chambers.

[0025] The stainless steel drum cover 13 is connected to the heat source pipe through a sealed bearing 40. The heat source pipe is connected to a hot air blower to introduce high-temperature hot air into the heat source cylinder cavity 11. The hot air is then dispersed into the sub-chamber through the drying holes on the surface of the stainless steel drum cover 13 to achieve drying. The rotating cylinder 10 rotates at a low speed to stir the internal materials, making the drying more uniform and efficient. The other end of the rotating cylinder 10 is provided with a conductive pressure relief hole 50 for pressure relief, and a protective film 60 is installed on the surface to improve safety.

[0026] Preferably, one side of the protective film 60 is attached to the upper side of the pressure relief hole 50. A PVC film with higher hardness can be selected and pressed to cover the pressure relief hole. Once the internal air pressure is too high, the lower end of the protective film 60 can be pushed open, thereby exposing the conductive pressure relief hole 50, which is highly practical.

[0027] The stainless steel cylinder cover 13 of the present invention is a non-straight cylinder. Furthermore, the inner diameters of the sub-chambers at both ends are larger than the inner diameter of the middle sub-chamber, so that the internal hot air channel has a tapered transition and the ventilation efficiency is high.

[0028] In addition, the partition plate 20 is fixedly connected to the stainless steel cylinder cover 13 and the side wall of the rotating cylinder 10, and is configured as a hollow plate to reduce the mass.

[0029] In summary, the utility model sets a stainless steel cylinder cover 13 in the rotating cylinder 10 to separate it into a heat source cylinder chamber 11 and a drying working chamber 12, and then uses a partition plate 20 to divide the drying working chamber 12 into three chambers, which can accommodate multiple groups of different nylon raw materials for filling, and then opens the heat source pipeline to complete the drying work. It is practical, convenient and efficient.

[0030] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
