Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a silk drying device. Background Art

[0002] Silk drying equipment is a specialized device used to dry silk cocoons to remove moisture and dry them to a suitable temperature for reeling or storage. The silk drying process requires controlled temperature, humidity, and ventilation to ensure the quality of the silk and the integrity of the fibers.

[0003] Currently, when drying silk cocoons, a strainer basket filled with silk cocoons is often placed directly into the drying equipment. As a result, the silk cocoons on the surface of the strainer basket can be dried quickly, while the silk cocoons inside the strainer basket have a small heating area, resulting in slow drying efficiency. If the silk cocoons are spread out on multiple drying trays to ensure the heating area, it is time-consuming and labor-intensive, and inconvenient to use.

[0004] In view of the above problems, this utility model document proposes a silk drying device. Utility Model Content

[0005] The utility model provides a silk drying device, which solves the problem in the prior art that when drying silk cocoons, a strainer basket filled with silk cocoons is often placed directly into the drying equipment, resulting in the silk cocoons on the surface of the strainer basket being dried quickly, while the silk cocoons inside have a small heating area, resulting in slow drying efficiency; if the silk cocoons are spread flat on multiple drying trays to ensure the heating area, it is time-consuming and labor-intensive, and inconvenient to use.

[0006] The utility model provides the following technical solutions:

[0007] A silk drying device, comprising:

[0008] A drying drum, the top of which is clamped with a drum cover, the inner wall of which is provided with an annular array of electric heating rods for heating air, and a door for convenient material removal which is installed at the opening of the side wall of the drying drum through a hinge;

[0009] The blast tumbling component is located at the bottom of the drying drum and is used to tumble the cocoons in the drying drum to increase the heating area.

[0010] In one possible design, the blast tumbling assembly includes a conical air expansion seat connected to the bottom of the drying cylinder, the bottom of the conical air expansion seat is fixed with three supporting legs in a circular array, the center of the bottom of the conical air expansion seat is connected to an air supply pipe, and the other end of the air supply pipe is connected to a blower.

[0011] In a possible design, a protective filter disc is fixedly installed on the top of the conical air diffuser to prevent the cocoons from clogging the air duct.

[0012] In a possible design, a dehumidification pipe for discharging moist water vapor is connected to the center of the top of the cylinder cover, and a filter is fixedly installed on the top of the dehumidification pipe to prevent the cocoons from flying out.

[0013] In a possible design, the drying drum and the drum cover are fixed by four fasteners on the outer wall that are easy to open and close.

[0014] In one possible design, the cabin door is provided with an observation window with built-in anti-fog glass.

[0015] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0016] The working principle and usage process of this technical solution are as follows:

[0017] When in use, pour the cocoons to be dried into the drying drum, then align the drum cover with the slot on the top of the drying drum, and securely fasten the drum cover to the drying drum with four buckles. Turn on the power, start the electric heating rod and the blower. The electric heating rod begins to heat the air in the drying drum, while the blower blows strong air into the conical air expansion seat through the air duct. The hot air is evenly diffused in the conical air expansion seat, and the protective filter disc filters the air duct to prevent the cocoons or impurities from clogging the air duct. As the hot air continues to blow in, the cocoons in the drying drum begin to tumble, thereby increasing their heated area and improving drying efficiency. This tumbling effect helps to evenly heat all parts of the cocoon, avoiding problems such as local overheating or uneven drying.

[0018] During the drying process, the moisture within the cocoons gradually evaporates into vapor. This vapor rises to the area near the drum cover through convection within the drying drum and is discharged outside the drying unit through a dehumidification pipe. A filter at the top of the dehumidification pipe effectively prevents the cocoons from flying out with the vapor. The user can monitor the drying progress of the cocoons in the drying drum through the observation window on the drying chamber door. When the desired drying effect is achieved, the electric heater and blower are turned off, and the door is opened to remove the dried cocoons.

[0019] The utility model has the following beneficial effects:

[0020] This new model uses an electric heating rod and a blower to achieve rapid circulation of hot air within the drying drum and tumble drying of the cocoons, greatly improving drying efficiency. The cocoons tumble continuously during the drying process, increasing the heated area and ensuring uniform heating of all parts of the cocoon, avoiding local overheating or uneven drying.

[0021] The design of the moisture-draining pipe and the filter screen of the utility model effectively removes the moist water vapor generated during the drying process, prevents the accumulation of water vapor in the drying drum, and ensures the dryness of the drying environment.
