Description

Technical Field

[0001] The present application relates to the technical field of chemical spinning production equipment, and particularly relates to a hot air conveying device at the bottom of a chip drying tower. Background Art

[0002] During the chip drying process, there is a problem that the bottom of the traditional drying tower cannot be dried. Since the volume of the hot air conveyed is large, in order to cover the entire drying tower and prevent excessive air volume from affecting the material feeding, the air inlet is often set at a position slightly above the conical bottom of the drying tower, resulting in the chips in the area below the air inlet not being fully dried. When starting up, a large amount of raw materials in the lower cone part need to be discharged before the quality of the dried raw materials can meet the production requirements. During the drying process, due to the small density of hot air, the hot air enters the drying tower from a single port and directly escapes upward, making it difficult to effectively dry the lower part and the lower cone of the drying tower.

[0003] Therefore, it is necessary to provide a hot air conveying device at the bottom of a chip drying tower to solve the above problems.

[0004] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0028] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] As Figures 1 to 5 shown, the present application provides a hot air conveying device at the bottom of a slicing drying tower, including a drying tower 1, a main hot air pipeline 2 is provided on one side of the drying tower 1, and an air extraction assembly 3 for conveying hot air is provided at the lower conical part of the drying tower 1;

[0031] Ventilation mesh holes 11 are opened at the lower conical part of the drying tower 1, and multiple groups of ventilation mesh holes 11 are equidistantly opened along the circumferential direction of the drying tower 1;

[0032] The air extraction assembly 3 includes a side hot air pipeline 31 connected to the lower end of the main hot air pipeline 2, a connecting pipe 33 connected to the side hot air pipeline 31, and an annular body 32 connected to one end of the connecting pipe 33. The annular body 32 is located outside the lower conical part of the drying tower 1 and seals and wraps multiple groups of ventilation mesh holes 11. The diameter of the side hot air pipeline 31 is smaller than the diameter of the main hot air pipeline 2, so that the main hot air pipeline 2 can convey sufficient hot air into the drying tower 1.

[0033] In this embodiment, the lower conical part of the drying tower 1 is wrapped by the annular body 32. When the main hot air duct 2 conveys hot air into the drying tower 1, part of the hot air will enter the annular body 32 through the side hot air duct 31 and the connecting pipe 33. The hot air inside the annular body 32 can enter the lower conical part of the drying tower 1 through the ventilation mesh holes 11 opened in the conical part of the drying tower 1, so that the raw materials inside the lower conical part of the drying tower 1 can be dried, thereby obtaining completely and sufficiently dried slices, and preventing waste caused by the inability to dry the raw materials in the lower conical part of the drying tower 1.

[0034] As Figure 2 shown, a flow regulating valve 34 is installed between the side hot air duct 31 and the connecting pipe 33, and the flow regulating valve 34 is used to control the hot air flow entering the annular body 32.

[0035] In this embodiment, by installing the flow regulating valve 34, the hot air flow entering the annular body 32 can be effectively controlled, making the equipment operate more stably.

[0036] As Figures 4 to 5 shown, the annular body 32 includes a first half-ring 321 and a second half-ring 322. The first half-ring 321 and the second half-ring 322 are symmetrically arranged, and the first half-ring 321 and the second half-ring 322 are made of stainless steel. The first half-ring 321 and the second half-ring 322 made of stainless steel can avoid rusting and further ensure their service life;

[0037] On the outer side of the first half-ring 321, first connecting plates 3211 are symmetrically arranged. On the outer side of the second half-ring 322, second connecting plates 3221 are symmetrically arranged. On one side of the first connecting plate 3211, positioning columns 3212 are provided. On one side of the second connecting plate 3221, positioning holes 3222 are opened. The positioning holes 3222 are adapted to the positioning columns 3212. Through holes 325 for bolts to pass through are opened on both the first connecting plate 3211 and the second connecting plate 3221. The first connecting plate 3211 and the second connecting plate 3221 are connected by bolts.

[0038] In this embodiment, when installing the annular body 32, the first half-ring 321 and the second half-ring 322 are placed on the conical part of the drying tower 1 for combination. During the combination, first insert the positioning columns 3212 into the positioning holes 3222 to prevent the positions of the first half-ring 321 and the second half-ring 322 from shifting. Subsequently, connect them by passing bolts through the through holes 325 on the first connecting plate 3211 and the second connecting plate 3221, and the assembly of the annular body 32 can be completed.

[0039] As Figures 1 to 2As shown, grooves 323 are provided on the opposite sides of the first half-ring 321 and the second half-ring 322. A sealing strip 324 is provided inside the groove 323, and the sealing strip 324 is a component made of rubber material.

[0040] In this embodiment, when the first half-ring 321 and the second half-ring 322 are assembled at the conical part of the drying tower 1, the rubber sealing strip 324 can effectively achieve a sealing effect and prevent waste of resources caused by leakage of hot air flow.

[0041] As Figure 4 shown, a flow guide vane 326 is provided inside the first half-ring 321, and the flow guide vane 326 is arc-shaped.

[0042] In this embodiment, when the hot air passes through the connecting pipe 33 and enters the annular body 32, the hot air flow follows the arc-shaped flow guide vane 326 to the bottom of the annular body 32 and rotates and flows to fill the annular body, and can be evenly introduced into the ventilation mesh holes 11 so that the material can be fully and evenly dried.

[0043] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
