Technical Field
[0001] The present application relates to the technical field of powder stirring devices, and in particular to an environmentally friendly material drying device. Background Art
[0002] Many industries involve powdered or granular raw materials containing large amounts of water or solvents during production. For example, in the chemical industry, certain chemical reactions may produce products in the form of wet powders or granules. In the food industry, these products may contain a certain amount of water, such as powders obtained by concentrating fruit juice, or wet food raw material granules produced through processes such as fermentation. These powders and granules can present numerous problems if not dried.
[0003] In the production of environmentally friendly powdered granules, material drying is a crucial step. Traditional drying equipment often suffers from numerous problems: 1. Traditional drying equipment lacks effective material stirring and guiding mechanisms. Environmentally friendly materials, especially powdered and granular materials, tend to accumulate during the drying process, preventing the internal particles from being fully exposed to heat. 2. Many drying equipment uses simple heating methods, such as a single heating source or simple hot air circulation. This method can easily lead to large temperature differences at different locations within the drying chamber, resulting in uneven heating of the environmentally friendly materials during the drying process. 3. There is a lack of effective treatment for the moisture generated during the drying process.
[0004] In view of the above problems, there is an urgent need for an environmentally friendly material drying device that can effectively solve the above shortcomings, so as to improve the drying effect, increase the drying efficiency, and ensure the production quality of environmentally friendly material particles.

[0018] The beneficial effects of this application are:
[0019] The heat exchange mechanism of the present application features multiple heating elements evenly distributed on the inner wall of the drying tank, and the heating elements are equipped with fins. This design increases the heating area, enabling heat to be more evenly distributed within the drying tank. The presence of a heat transfer plate further optimizes heat transfer. The heat transfer plate is cylindrical, with fins disposed between the heating elements and the heat transfer plate. The spiral guide grooves on the surface of the heat transfer plate guide the movement of the environmentally friendly material particles, allowing the particles to fully absorb heat during movement, ensuring uniform heating of the material during the drying process.

Although exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the specific embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.
[0032] In the following description, numerous specific details are provided to provide a more thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present application; that is, all features of actual embodiments are not described herein, nor are well-known functions and structures described in detail.
[0033] In the drawings, the sizes of layers, regions, elements and their relative sizes may be exaggerated for clarity. Like reference numerals denote like elements throughout.
[0034] It should be understood that when an element or layer is referred to as being "on," "adjacent to," "connected to," or "coupled to" another element or layer, it may be directly on, adjacent to, connected to, or coupled to the other element or layer, or there may be intervening elements or layers. Conversely, when an element is referred to as being "directly on," "directly adjacent to," "directly connected to," or "directly coupled to" another element or layer, there may be no intervening elements or layers. It should be understood that although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are merely used to distinguish one element, component, region, layer, or part from another element, component, region, layer, or part. Therefore, without departing from the teachings of the present application, the first element, component, region, layer, or part discussed below may be represented as a second element, component, region, layer, or part. And when the second element, component, region, layer, or part is discussed, it does not necessarily mean that the first element, component, region, layer, or part is present in the present application.
[0035] Spatially relative terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein for convenience of description to describe the relationship of an element or feature shown in the figures to other elements or features. It should be understood that in addition to the orientations shown in the figures, the spatially relative terms are intended to include different orientations of the device in use and operation. For example, if the device in the drawings is flipped, then the elements or features described as "under the other elements" or "under it" or "under it" will be oriented as "on" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatial descriptors used herein are interpreted accordingly.
[0036] The purpose of the terms used herein is only to describe specific embodiments and is not intended to limit the present application. When used herein, the singular forms "a", "an", and "the" are intended to include the plural forms, unless the context clearly indicates otherwise.

When used herein, the term "and / or" includes any and all combinations of the relevant listed items.
[0037] In order to fully understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below. However, in addition to these detailed descriptions, the present application may also have other implementation methods.
[0038] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides an environmentally friendly material drying device, a drying tank body 1, the drying tank body having a feed port 11 and a discharge port 12, the feed port is used to input environmentally friendly material particles to be dried, and the discharge port is used to discharge the dried environmentally friendly material particles;
[0039] Heat exchange mechanism 2, comprising a plurality of heating elements 21, which are evenly distributed on the inner wall of the drying tank, and each heating element is provided with fins 22, which are distributed on the surface of the electric heating tube;
[0040] a heat conduction plate 3, the heat conduction plate being cylindrical, the fins being disposed between the heating element and the heat conduction plate, the heat conduction plate having a spiral guide groove 4 on its surface, a flow channel 6 formed within the heat conduction plate, and an air outlet 61 communicating with the flow channel formed on the surface of the guide groove;
[0041] The stirring assembly 5 includes a stirring shaft 51 and a stirring paddle 52 provided on the stirring shaft. The side wall of the stirring paddle is in conflict with the heat conduction plate. When the external drive motor drives the stirring paddle to rotate, the stirring paddle pushes the environmentally friendly material particles in the drying tank into the guide groove and moves in the guide groove.
[0042] As you can understand, the heat generated by the heating element is transferred to the heat conduction plate through the fins. Simultaneously, the fins come into contact with the environmentally friendly material particles within the drying tank, heating them. As the agitator paddle rotates, it forces the environmentally friendly material particles within the drying tank into the guide grooves, where they are heated and dried.
[0043] In this embodiment, the stirring paddle is tilted, with the angle between the stirring paddle and the stirring shaft being between 30 and 45 degrees. As the stirring paddle rotates, the tilted stirring paddle generates a force component on the environmentally friendly material particles along the direction of the guide groove, thereby promoting the movement of the environmentally friendly material particles. In other embodiments, the stirring paddle is provided with a top plate that matches the guide groove, and the top plate drives the movement of the environmentally friendly material particles.
[0044] In an alternative embodiment, if Figure 4 As shown, the drying tank body is further provided with an exhaust mechanism 7, which includes an exhaust pipe 71 and an exhaust valve 72 arranged on the exhaust pipe. The exhaust pipe is connected to the top of the drying tank body and is used to discharge the exhaust gas generated during the drying process.
[0045] It is understood that during the drying process of the environmentally friendly material pellets, moisture remaining in the environmentally friendly material pellets will diffuse throughout the drying tank. If this moisture is not promptly expelled, there is a risk of secondary adhesion to the surface of the environmentally friendly material pellets, thereby affecting the drying efficiency of the environmentally friendly material pellets. Furthermore, as the humidity within the drying tube increases, the volatilization rate of the moisture within the environmentally friendly material pellets decreases. In this embodiment, the exhaust mechanism promptly exhausts the high-humidity air within the drying tank, reducing the humidity of the drying tank and promoting the drying of the environmentally friendly material pellets.
[0046] like Figure 3 As shown, in an optional embodiment, the flow channel is connected to a gas supply assembly 62, and heated gas is supplied to the flow channel through the gas supply assembly.
[0047] In this embodiment, the gas passes through the device to transport heated high-pressure gas into the flow channel, and the gas is blown onto the surface of the environmentally friendly material particles in the guide groove through the gas outlet of the flow channel, and the environmentally friendly material particles are dried by hot air.
[0048] In an optional embodiment, the air outlet is provided with a baffle assembly 8, which prevents environmentally friendly materials from entering the air outlet. The air outlet is located at the upper part of the side wall of the guide groove.
[0049] A baffle assembly is provided at the air outlet of the exhaust pipe, and the baffle assembly includes a baffle and a return spring. The lower end of the baffle is rotatably connected to the exhaust pipe, and a return spring is connected between the lower end of the baffle and the exhaust pipe. When no airflow enters the exhaust pipe, the baffle assembly is in a closed state, the baffle covers the surface of the air outlet, and the air outlet is closed, thereby preventing the environmentally friendly material particles in the guide groove from entering the exhaust pipe. When airflow enters the exhaust pipe, the airflow will push open the baffle provided with one end of the return spring, and the airflow can be discharged from the gap.
[0050] In an optional embodiment, the stirring paddle is provided with a temperature sensor, and the temperature of the environmentally friendly material particles in the drying tank is detected in real time by the temperature sensor.
[0051] In this embodiment, the temperature of the environmentally friendly material particles in the drying tank is detected in real time by a temperature sensor. As the stirring paddle rotates, the temperature sensor can monitor the temperature of each point in the drying tank in real time, thereby controlling the drying temperature.
[0052] It is understandable that during the drying process, it is necessary to ensure that the temperature of the dried environmentally friendly material particles is within an appropriate temperature range, while ensuring that the environmentally friendly material particles are provided with an appropriate drying temperature while avoiding excessively high temperatures that may cause the environmentally friendly material particles to deteriorate.
[0053] In an optional embodiment, a protrusion 41 is provided on the bottom wall of the guide groove, and the cross section of the protrusion is hemispherical.
[0054] By providing a raised portion on the bottom wall of the guide groove, the raised portion can increase the contact area between the environmentally friendly material particles and the guide groove, thereby improving the drying efficiency of the environmentally friendly material particles. At the same time, the hemispherical structure of the raised portion can avoid the formation of dead corners where environmentally friendly material particles are easily accumulated.
[0055] In an optional embodiment, the exhaust mechanism is connected to the gas-liquid separation mechanism 73 .
[0056] The gas discharged from the exhaust mechanism is mixed with a large amount of water vapor. The water and air are separated by the gas-liquid separation mechanism, so as to better treat the exhaust gas discharged from the exhaust mechanism.
[0057] In an optional embodiment, the side wall of the guide groove is arranged at an angle, and an arc-shaped transition surface is provided between the side wall of the guide groove and the bottom wall of the guide groove.
[0058] In this embodiment, the cross-section of the guide groove is generally trapezoidal, and the inclined sidewalls can effectively prevent the adhesion of environmentally friendly material particles. The arc-shaped transition surface can eliminate the dead angle at the connection between the bottom wall and the side of the guide groove, thereby preventing the accumulation of environmentally friendly material particles.
[0059] In an optional embodiment, a filter screen 74 is provided at the end of the exhaust pipe, and the filter screen is located at one end of the exhaust pipe close to the drying tank.
[0060] It is understandable that since the material being dried in the drying tank is environmentally friendly material particles, the weight of environmentally friendly material particles is generally light. During the drying process of the environmentally friendly material particles, environmentally friendly material particles with small diameters will float in the air and enter the exhaust mechanism along with the discharge of exhaust gas. By providing a filter at the end of the exhaust pipe, the environmentally friendly material particles can be effectively prevented from entering the exhaust pipe.
[0061] In an optional embodiment, a plurality of infrared heating tubes 9 are provided on the stirring shaft, and the infrared heating tubes are located at the bottom of the stirring shaft.
[0062] An infrared heating tube is arranged at the bottom of the stirring shaft. When the stirring shaft rotates, the infrared heating tube can heat the environmentally friendly material particles and stir them at the same time.
[0063] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the claims. Various modifications and variations may be made to the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form additional embodiments of the present application that may not be explicitly described. Therefore, the above embodiments merely illustrate several implementations of the present application and do not limit the scope of protection of the patent application.
