Description

Technical Field

[0001] The utility model belongs to the field of thymol processing, and particularly relates to a drying system for thymol. Background Art

[0002] The production process of thymol usually involves the following steps: raw material collection: thymol is usually extracted from plants such as thyme. Extraction: Extract the extract containing thymol from plant materials through methods such as solvent extraction and distillation. Separation and purification: Use various separation techniques, such as chromatography, to separate thymol in the extract from other components and further purify it. Crystallization: Control the conditions to make thymol crystallize. Drying: Dry the crystallized thymol to remove moisture. Quality inspection: Conduct quality inspection on the final product to ensure that it meets relevant standards.

[0003] When drying thymol crystals, a drying oven is often used to remove moisture. However, for existing drying ovens, they are usually plug-in type drying ovens or drum type drying ovens. The plug-in type drying oven mainly places the material to be dried on a detachable plug board and makes the dried material spread out flat. During the drying process, the material remains stationary. In this way, it is necessary to ensure that the spreading thickness of the dried material is small to ensure good drying effect. Furthermore, it will be required that the overall area of the plug board is large to accommodate as many materials to be dried as possible. This type of plug-in type drying oven has cumbersome operation, large space occupation, and low efficiency. For the drum type drying oven, it uses a rotating method to make the material to be dried rotate in the drum so that the dried material is evenly heated and not restricted by space. However, during the flipping process of this type of drying oven, it is inevitable that the material to be dried will still accumulate to a certain extent due to gravity, resulting in uneven drying degrees of the inner and outer layer materials. Especially for the drying of thymol, too high temperature will cause its decomposition, and too low temperature will cause the moisture in the internal thymol to be unable to be effectively removed. It is difficult to control the overall drying uniformity of thymol crystals. Content of the Utility Model

[0004] An embodiment of the utility model provides a drying system for thymol to solve the problems in the prior art.

[0005] The embodiment of the utility model adopts the following technical solution: A drying system for thymol, comprising: a workbench; a drying cylinder, including an outer cylinder and an inner cylinder arranged inside the outer cylinder and driven to rotate by power. An openable and closable sealing door body is installed at the open end of the inner cylinder, and one end of the outer cylinder far from the open end of the inner cylinder is hinged to a first hinge seat on the workbench; a plurality of groups of turning plates are configured and distributed around the inner cylinder, and a material cavity is formed between adjacent two groups of turning plates; an angle adjustment component for adjusting the angle of the drying cylinder relative to the plane of the workbench.

[0006] Preferably, the angle adjustment assembly includes a first linear drive source, the output end of the first linear drive source is hinged to the outer cylinder, and the base end of the first linear drive source is hinged to a second hinge seat on the workbench.

[0007] Preferably, a fixed rod is coaxially installed in the drying cylinder, one end of each turning plate is connected to the fixed rod, and the turning plate is divided into a first area and a second area. The first area of the turning plate is the end close to the fixed rod, and a plurality of through holes are evenly arranged in the first area of the turning plate.

[0008] Preferably, the area ratio of the first area of the turning plate is not less than 2 / 3.

[0009] Preferably, a rotating shaft is coaxially provided at one end of the inner cylinder away from its open end. The rotating shaft passes through the cylinder wall of the outer cylinder and is rotatably connected thereto. A flange is provided at the open end of the inner cylinder, and an annular convex block is coaxially connected to the inner side end of the flange. The annular convex block is rotationally matched with the cylinder wall of the outer cylinder.

[0010] Preferably, a gap is formed between the inner cylinder and the outer cylinder. A heating layer and a heat insulation layer are arranged in the gap. The heat insulation layer is located outside the heating layer. Both the heat insulation layer and the heating layer are fixedly connected to the outer cylinder and do not contact the inner cylinder.

[0011] Preferably, a first arc-shaped support plate is inclinedly installed on the workbench. When the drying cylinder is turned to the lower limit position, the cylinder wall of the outer cylinder fits on the first arc-shaped support plate, and the open end of the inner cylinder is inclined downward.

[0012] Preferably, a second arc-shaped support plate and a second linear drive source are further provided on the workbench. The second arc-shaped plate is located between the drying cylinder and the workbench. At least one longitudinally extending guide rod is connected to the lower end of the second arc-shaped plate. The guide rod penetrates through the workbench and is slidably matched therewith. The second linear drive source is longitudinally installed on the workbench, and the output end of the second linear drive source is fixedly installed on the second arc-shaped plate; when the second arc-shaped plate is in the upper limit position and the drying cylinder rotates to a horizontal state, the outer cylinder fits on the second arc-shaped plate.

[0013] The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0014] First, while the drying cylinder of the present invention dries the raw materials inside it, the inner cylinder also rotates in real time. In this way, under the action of gravity and the rotational force of the inner cylinder, the raw materials in different material cavities are repeatedly turned over to ensure the overall drying uniformity of the thymol crystals, and avoid problems such as local overheating and decomposition of the thymol crystals or poor internal drying effect.

[0015] Second, the utility model is provided with a plurality of perforations on the material turning plate, so that when the inner cylinder rotates in a horizontal state, the thymol crystals inside can flow and be converted between several material cavities through the perforations, further improving the drying uniformity of the overall thymol crystals. The perforations arranged in the first area of the material turning plate indicate that the material turning plate in the second area is a solid plate. In this way, when the thymol crystals rotate with several material turning plates, most of the thymol crystals will fall into another material cavity through the perforations when they just move from the low point to the high point of the inner cylinder. At least part of the thymol crystals will be blocked by the second area of the material turning plate and move to a higher point and then fall due to gravity. In this way, it can be ensured that the thymol crystals are all brought to the high point. By the natural falling method of thymol, the accumulation of thymol is avoided, and its drying effect and drying uniformity are improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The technical solutions provided by each embodiment of the present utility model will be described in detail below in conjunction with the drawings.

[0027] Referring to Figures 1 to 6 As shown, an embodiment of the present utility model provides a drying system for thymol, including: a workbench 1; a drying cylinder 2, including an outer cylinder 21 and an inner cylinder 22 disposed inside the outer cylinder 21 and driven to rotate by power. A sealable door body 23 is installed at the open end of the inner cylinder 22, and one end of the outer cylinder 21 away from the open end of the inner cylinder 22 is hinged to the first hinge base 11 on the workbench 1; a material turning plate 3, configured with a plurality of groups and distributed around the inner cylinder 22, and a material cavity is formed between adjacent two groups of material turning plates; an angle adjustment assembly 4 for adjusting the angle of the drying cylinder 2 relative to the plane of the workbench 1.

[0028] During actual use, first, the angle adjustment assembly 4 adjusts the drying cylinder 2 to the upper limit position, that is, the open end of the inner cylinder 22 is inclined upward or directly upward. Generally, it is inclined upward. Then, the staff can open the sealing door body 23 to add or pour the thymol crystals to be dried into the inner cylinder 22, and close the sealing door body 23. Then, the angle adjustment assembly 4 adjusts the angle of the drying cylinder 2 again, so that the inner cylinder 22 is horizontally arranged, that is, the working position of the drying cylinder 2. While the drying cylinder 2 dries the raw materials inside it, the inner cylinder 22 also rotates in real time. In this way, the raw materials in different material cavities can be repeatedly turned under the action of gravity and the rotational force of the inner cylinder 22 to ensure the overall drying uniformity of the thymol crystals and avoid problems such as local overheating and decomposition of the thymol crystals or poor internal drying effect.

[0029] Specifically, as shown in Figure 1 and Figure 2 , the angle adjustment component 4 includes a first linear drive source 41. The output end of the first linear drive source 41 is hinged to the outer cylinder 21, and the base end of the first linear drive source 41 is hinged to a second hinge seat on the workbench 1. By operating the first linear drive source 41, the angle of the drying cylinder 2 can be adjusted. The first linear drive source 41 adopts a drive source such as a hydraulic cylinder or an electric linear cylinder to achieve precise control of the angle of the inner cylinder 22.

[0030] Specifically, as shown in Figure 4 and Figure 5 , a rotating shaft 221 is coaxially provided at one end of the inner cylinder 22 away from its open end. The rotating shaft 221 passes through the cylinder wall of the outer cylinder 21 and is rotatably connected thereto. A flange 222 is provided at the open end of the inner cylinder 22. An annular convex block 223 is coaxially connected to the inner side end of the flange 222. The annular convex block 223 is rotationally matched with the cylinder wall of the outer cylinder 21. The rotational connection between the inner cylinder 22 and the outer cylinder 21 is achieved through the rotating shaft 221 and the annular convex block 223.

[0031] Specifically, a gap 25 is formed between the inner cylinder 22 and the outer cylinder 21 (as shown in Figure 5 ). A heating layer 26 and a heat insulation layer 27 are provided in the gap 25. The heat insulation layer 27 is located outside the heating layer 26. Both the heat insulation layer 27 and the heating layer 26 are fixedly connected to the outer cylinder 21 and do not contact the inner cylinder 22.

[0032] The heat insulation layer 27 usually adopts resistance wires (such as nickel-chromium alloy wires), electromagnetic heating coils, etc.; the resistance wires are usually wound around the inside of the drying cylinder 2 (i.e., at the gap 25 between the outer cylinder 21 and the inner cylinder 22) in a spiral shape or other specific layout patterns; the electromagnetic heating coils are arranged according to the design requirements to achieve uniform heating of the materials in the cylinder.

[0033] Common materials for the heat insulation layer 27 include rock wool, glass fiber, aluminum silicate fiber, etc. These materials have a low thermal conductivity and can effectively reduce heat dissipation. The heat insulation layer 27 evenly covers the outside of the heating layer to form a relatively complete heat insulation layer to reduce the transfer of heat to the external environment.

[0034] In some practical applications:

[0035] As shown in Figure 5 and Figure 6 , a fixed rod 24 is coaxially installed in the drying cylinder 2. One end of each turning plate 3 is connected to the fixed rod 24. The turning plate 3 is divided into a first area and a second area. The first area of the turning plate 3 is the end close to the fixed rod 24. A plurality of through holes 31 are evenly arranged in the first area of the turning plate 3. The area ratio of the first area of the turning plate 3 is not less than 2 / 3.

[0036] In this embodiment, a number of through holes 31 are provided on the turnover plate 3. When the inner cylinder 22 rotates in a horizontal state, the thymol crystals inside it can flow and convert between several material cavities through the through holes 31, further improving the drying uniformity of the overall thymol crystals. The arrangement of the through holes 31 in the first area of the turnover plate 3 means that the turnover plate 3 in the second area is a solid plate. When the thymol crystals follow several turnover plates 3 to rotate, most of the thymol crystals will fall into another material cavity through the through holes 31 when they just move from the low point position to the high point position of the inner cylinder 22. And at least part of the thymol crystals will be blocked by the second area of the turnover plate 3 and move to a higher position and then fall due to gravity. In this way, it can be ensured that the thymol crystals are all brought to the high point position. By the way of natural dropping of thymol, the accumulation of thymol is avoided, and its drying effect and drying uniformity are improved.

[0037] In some other practical applications:

[0038] Such as Figures 1 to 3 As shown, a first arc-shaped support plate 12 arranged obliquely can also be installed on the workbench 1. When the drying cylinder 2 is turned to the lower limit position, the outer cylinder 21 wall fits on the first arc-shaped support plate 12, and the open end of the inner cylinder 22 is inclined downward. The support of the drying cylinder 2 by the first arc-shaped support plate 12 is for the convenience of discharging the thymol. It should be noted that before discharging, tools such as a hopper need to be prepared in advance to receive at the open end of the inner cylinder 22.

[0039] Specifically, a second arc-shaped support plate 13 and a second linear driving source 14 are also provided on the workbench 1. The second arc-shaped plate is located between the drying cylinder 2 and the workbench 1. At least one longitudinally extending guide rod 131 is connected to the lower end of the second arc-shaped plate. The guide rod 131 penetrates the workbench 1 and is slidably matched with it. The second linear driving source 14 is longitudinally installed on the workbench 1 and the output end of the second linear driving source 14 is fixedly installed on the second arc-shaped plate; when the second arc-shaped plate is in the upper limit position and the drying cylinder 2 rotates to a horizontal state, the outer cylinder 21 fits on the second arc-shaped plate;

[0040] Since the inner cylinder 22 is in the horizontal state as the working position, only through the first transfer base and the first linear driving source 41, the drying cylinder 2 cannot be effectively supported. Therefore, by setting the second arc-shaped plate that can be lifted, the drying cylinder 2 can be appropriately supported to ensure its stability.

[0041] Specifically, a second pulley 15 is installed on the rotating shaft 221, and a rotary drive source 16 is installed at the end of the outer cylinder 21 through a motor bracket. A first pulley 17 is installed on the output shaft of the rotary drive source 16. The first pulley 17 is in transmission connection with the second pulley 15 through a transmission belt 18. When the rotary drive source 16 operates, it can drive the first pulley 17 and the second pulley 15 to rotate, thereby realizing the rotation of the entire inner cylinder 22.

[0042] The above are only the embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
