Description

Technical Field

[0001] This utility model relates to the field of drying cylinder technology, and in particular to a drying cylinder for an eight-basket drying oven. Background Technology

[0002] The eight-basket drying oven is an existing drying equipment used to test the moisture regain of loose fibers and wool tops. The currently used drying cylinder has a mesh structure at the bottom and a cylindrical structure surrounded by aluminum sheet on the side walls. In actual drying process, this causes poor internal hot air circulation, resulting in loose fibers escaping and seriously affecting drying efficiency. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a drying cylinder for an eight-basket drying oven, which effectively improves the circulation of hot air within the drying cylinder, thereby enhancing drying efficiency.

[0004] This utility model discloses a drying cylinder for an eight-basket drying oven, including a base and a cylinder body. The base is formed by welding cross-shaped metal strips, and the cross-section of the metal strips is rectangular. The cylinder body includes a circular bottom plate and an annular cylinder wall. The bottom plate is fixed to the base, and the cylinder wall is fixed to the outer edge of the bottom plate and connected as a whole. A vertically upward support strip is provided at the end of the metal strips of the base, and the support strip is fixedly connected to the cylinder wall. Screen holes are evenly arrayed on the bottom plate and cylinder wall of the cylinder body, and the aperture of the screen holes is 22±2μm.

[0005] A through hole is provided at the center of the bottom plate of the cylinder. A central cylinder is provided on the bottom plate inside the cylinder. The lower end of the central cylinder is fitted and fixed to the outer edge of the through hole. A top plate is provided to seal the top of the central cylinder. Screen holes are evenly arrayed on the side wall and top plate of the central cylinder. A support ring is provided on the outer edge of the through hole on the lower surface of the bottom plate. The end of the metal strip is welded to the outer wall of the support ring. The support ring and the base form an integral structure.

[0006] The aperture of the sieve holes on the central cylinder is 22±2μm, and the aperture of the sieve holes on the top plate is 18±2μm.

[0007] The metal strip of the base is 2cm thick and 10cm wide; the cross-sectional width of the support ring is 10cm and the thickness is 2cm; the width of the support strip is 10cm and the thickness is 2cm.

[0008] The present invention provides an eight-basket drying cylinder with sieve holes arrayed on its bottom and side walls, allowing hot air output from the bottom of the drying oven to flow inside the drying cylinder. At the same time, a central cylinder is set in its center, which can further transport hot air from the inside to the outside, thereby improving the drying efficiency of loose fibers, wool tops, etc., and ensuring a uniform and thorough drying effect.

Detailed Implementation

[0010] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0011] Example 1: like Figures 1-4 As shown, this utility model discloses a drying cylinder for an eight-basket drying oven, including a base 1 and a cylinder 2. The base 1 is formed by welding together cross-shaped metal strips 11, and the cross-section of the metal strips 11 is rectangular. The cylinder 2 includes a circular bottom plate 21 and an annular cylinder wall 22. The bottom plate 21 is fixed to the base 1, and the cylinder wall 22 is fixed to the outer edge of the bottom plate 21 and connected as a whole. A vertically upward support strip 4 is provided at the end of the metal strips 11 of the base 1. The support strip 4 is fixedly connected to the cylinder wall 22. A sieve hole 5 is evenly arrayed on the bottom plate 21 and the cylinder wall 22 of the cylinder 2. The sieve hole 5 has a diameter of 22±2μm.

[0012] A base 1 is located below the cylinder 2, and the base 1 is welded together from cross-shaped metal strips 11, which can be made of stainless steel. The cross-section of the metal strips 11 is rectangular, making the entire base 1 more stable when placed inside the eight-basket drying oven. The bottom plate 21 of the cylinder 2 is welded and fixed to the base 1. Screen holes 5 are provided on both the bottom plate 21 and the cylinder wall 22 of the cylinder 2. This allows hot air from the bottom to move into the cylinder 2 and flow to the outside, circulating among the loose fibers and slivers inside the cylinder 2, thus achieving more efficient and thorough drying. Furthermore, the cross-shaped metal strips 11 of the base 1 create a gap between the bottom plate 21 of the cylinder 2 and the worktable of the eight-basket drying oven, allowing for ample hot air circulation and ensuring more thorough and uniform drying of the materials inside the cylinder 2. The aperture of the sieve holes 5 on the bottom plate 21 and the cylinder wall 22 is 22±2μm. The density of the sieve holes 5 is arranged according to actual needs. This ensures that when hot air flows stably, there is less chance of loose fibers escaping, thus ensuring the accuracy of data such as the moisture content and regain of loose fibers and wool slivers.

[0013] A through hole is provided at the center of the bottom plate 21 of the cylinder 2. A central cylinder 3 is provided on the bottom plate 21 inside the cylinder 2. The lower end of the central cylinder 3 is fitted and fixed to the outer edge of the through hole. A top plate 6 is provided to close the top of the central cylinder 3. Screen holes 5 are evenly arrayed on the side wall of the central cylinder 3 and the top plate 6. A support ring 12 is provided on the outer edge of the through hole on the lower surface of the bottom plate 21. The end of the metal strip 11 is welded to the outer wall of the support ring 12. The support ring 12 and the base 1 form an integral structure. A through hole is provided inside the bottom plate 21, and the central cylinder 3 is provided on the outer edge of the through hole. At the same time, the support ring 12 is provided on the lower surface of the bottom plate 21. The support ring 12 is located on the outer edge of the through hole. In this way, the inside of the through hole is not covered by the base 1, so as to ensure unobstructed airflow inside. Loose fibers or wool tops are located between the central cylinder 3 and the cylinder 2, and their overall thickness is reduced. External hot air can enter the inside of the cylinder 2 from the inside and outside, so that the loose fibers or wool tops are dried more thoroughly and evenly. It can also effectively shorten the drying time and improve the drying efficiency.

[0014] The aperture of the sieve holes 5 on the central cylinder 3 is 22±2μm, and the aperture of the sieve holes 5 on the top plate 6 is 18±2μm. The aperture of the central cylinder 3 is the same as that on the cylinder wall 22 and the bottom plate 21, while the aperture of the top cover is smaller than that on the central cylinder 3. This ensures that the hot air transported upward from the central cylinder 3 will not be completely discharged directly from the top plate 6. Therefore, some hot air can only be transported from the central cylinder 3 into the cylinder 2, ensuring that the loose fibers and slivers in the cylinder 2 are dried more quickly, efficiently, uniformly, and thoroughly. The limitation of the aperture size is also to prevent loose fibers from escaping.

[0015] The metal strip 11 of the base 1 has a thickness of 2cm and a width of 10cm; the cross-sectional width of the support ring 12 is 10cm and the thickness is 2cm; the width of the support strip 4 is 10cm and the thickness is 2cm.

[0016] The metal strip 11 of the base 1 is 10cm wide, which ensures stability when placed on the workbench and reduces obstruction of the base plate 21, thereby improving the flow of hot air.
