Description

  The present invention relates to a rotary dryer, and more particularly, to a dryer that is dried by sunlight while progressing in a longitudinal direction inside a cylinder body to be dried or through a plurality of stages.

  In general, drying is a unit operation that removes moisture using heat, air flow, electromagnetic waves, etc. on the material to be dried, and in all industrial processes such as intermediate processing, transportation, post-processing and final products, It is a general-purpose technology that is indispensably used. Currently, the most widely used technology is hot air drying or radiation drying, and there are methods using far-infrared lamps, planar heating elements, etc. And its effectiveness is low.

  Also, conventional dryers usually use hot air and have a drying speed that is faster than natural drying, but there is a difference in performance such as a large deviation in moisture content and poor quality of the material to be dried. In addition, the efficiency of power consumption is low, so the economy is low, and there are secondary problems such as inducing environmental problems.

  Recently, dryers of various structures have been developed to allow the material to be dried to better contact hot air and increase its contact area and time in order to increase drying efficiency and lower final moisture content.

  However, such a dryer according to the prior art has a plurality of shells of drums or heating chambers arranged in parallel or in series, so that not only a large installation area is required, but also a space where drying is performed, that is, There is a problem that the drying space is larger than necessary. Further, although hot air must be continuously supplied to the drum and the heating chamber, there is a problem that excessive energy is input to the drying process due to the large drying space.

  Moreover, although the dryer using a solar heat is disclosed by the multipurpose dryer using the solar heat of Korean publication number 10-2014-0053573, in the case of a solar heat, since it is an indirect use system which converts light into heat and uses it. However, there is a problem that the heat collecting equipment must be installed in a large area for efficient drying, which is less efficient than sunlight.

  On the other hand, natural drying using existing sunlight is a method of drying the material to be dried in a wide area and drying it naturally, and the drying time is long, the influence of outside air is very large, and it takes time and effort. Because it is a labor intensive method, there was a limit to drying agricultural and marine products in small quantities.

  As shown in FIGS. 1 to 5, a continuous rotary solar dryer according to an embodiment of the present invention includes a drying unit 100 that receives supply of an object to be dried from an input port (i) and discharges it to a discharge unit. In addition, the drying unit 100 includes an input unit 200 in which an object to be dried is input, and a blower unit 190 that discharges exhaust gas from the drying unit 100.

  The drying unit 100 has a tube-shaped first tube portion 110 and a tube shape that houses the first tube portion 110, and the first object is a material to be dried received from the discharge port (o) of the first tube portion 110. A tubular body that accommodates the second cylindrical portion 120 and the second cylindrical portion 120 that are advanced in the direction opposite to the portion 110, that is, in the direction from the discharge port (o) of the first cylindrical portion 110 to the charging port (i), The material to be dried received from the second cylinder part 120 is provided by the third cylinder part 130 that advances in the same direction as the first cylinder part 110. Here, since the discharge port (o) is provided in a shape in which the end portion of the first tube portion is opened, it means the open end portion of the first tube portion.

  In order to press-fit the material to be dried into the first cylinder part 110, the input part 200 into which the object to be dried is introduced includes a transfer pipe 210 connected to the first cylinder part 110, and a transfer screw 220 that rotates inside the transfer pipe 210. The motor 230 for rotating the transfer screw 220 may be further provided.

  On the other hand, the roller 150 that rotates the third cylindrical portion 130, the horizontal frame 160 that is installed on the floor surface where the continuous rotary solar dryer according to the present invention is installed, and the horizontal frame 160 are connected to the first. A vertical frame 170 that supports the three cylinder portions 130, an exhaust portion 181 that is connected to the horizontal frame 160 and exhausts exhaust gas (g) generated in the drying process, and a to-be-dried object that discharges an object to be dried after drying. An object discharge unit 182.

  The first cylinder part 110, the second cylinder part 120, and the third cylinder part 130 are all tubular, and are all formed of a light-transmitting material so that sunlight can pass through. Transparent materials such as polycarbonate and PVC can be selected as the light-transmitting material, as well as glass. From the aspect that photochemical durability and off-the-shelf products can be used, an acrylic tube is used. desirable. Thereby, sunlight can pass the 3rd cylinder part 130, the 2nd cylinder part 120, and the 1st cylinder part 110 in order, and the to-be-dried object which exists in the inside of a drying part can be dried with sunlight.

  At this time, in order to provide stronger sunlight to the object to be dried, a light collecting means may be provided. The condensing means can include a reflecting plate 300 and a reflecting plate driving means (not shown). The reflecting plate 300 is a means for condensing the object to be dried by reflecting sunlight. Further, it can be made of a polished metal material or a mirror. In FIGS. 1 and 2, an example in which the reflecting plate 300 has a flat plate shape and is symmetrically disposed two by two around the third cylindrical portion 130 is illustrated. The reflector 300 may be a curved plate, and the number and size thereof can be increased or decreased as necessary. The reflector driving means is for adjusting the angle and the installation angle of the reflector 300 according to the position of the sun, and can be constituted by an automatic drive device including an actuator. It can also be configured with a manual drive device. In any case, a specific mechanical configuration can be realized by ordinary knowledge.

  Since the first cylinder part, the second cylinder part 120, and the third cylinder part 130 rotate and do not matter even if the rotation directions are the same, they rotate together. Transfer members 111, 121, and 131 are provided on the inner peripheral surfaces of the first tube portion, the second tube portion 120, and the third tube portion 130. The transfer members 111, 121, and 131 will be described in detail separately. As described above, as each tube portion rotates, the object to be dried can move along the length direction of each tube portion. On the other hand, a recirculation pipe 142 (to be described later) is disposed at an end portion of the first cylindrical portion 110 close to the inlet (i) side.

  The transfer members 111, 121, and 131 are installed in a plate shape of a light transmissive material that protrudes from the inner peripheral surfaces of the first cylinder part 110, the second cylinder part 120, and the third cylinder part 130.

  The transfer members 111, 121, and 131 will be described with reference to the second transfer member 121 installed in the second cylindrical portion 120 as an example.

  On the inner peripheral surface of the second cylinder part 120, a plurality of second transfer members 121 that accommodate a material to be dried and transfer it along the rotation direction of the second cylinder part 120 are arranged intermittently. By such a second transfer member 121, the material to be dried is accommodated on one surface side of the second transfer member 121 formed on the lower side of the second cylinder part 120, and the second cylinder part 120 rotates. It rises with it and falls toward the 1st cylinder part 110 from the 2nd cylinder part 120 upper side. That is, due to the rotation of the second cylinder part 120, the material to be dried accommodated on the one surface side of the second transfer member 121 below the second cylinder part 120 is pulled up and transferred in the rotation direction, and then the second cylinder part 120. Falls from above. Here, in order to easily accommodate the material to be dried on the one surface side of the second transfer member 121, the second transfer member 121 may have a flat plate shape bent from the flat plate shape or a curved plate shape. .

  By such an action, the object to be dried is evenly distributed inside the second cylindrical portion 120, and therefore the time for the object to be dried to be exposed to sunlight is increased, and the drying efficiency is improved.

  In addition, the second transfer member 121 is transferred along the direction in which the material to be dried is rotated by the second cylinder part 120 from the discharge port (o) of the first cylinder part 110 toward the input port (i). As a result, the second cylindrical portion 120 is arranged obliquely with respect to the length direction. The inclination angle is desirably 5 ° to 10 ° downward with respect to a line approaching the discharge port (o) from the discharge port (o), but is not necessarily limited thereto.

  Both end portions of the third cylindrical portion 130 are connected to and supported by the vertical frame 170 and the discharge portion 182, respectively, and a protruding portion 132 is formed on the outer peripheral surface. Since the protruding portion 132 meshes with a roller 150 described later, when the roller 150 rotates, the third cylindrical portion 130 rotates.

  In addition, a plurality of third transfer members 131 are provided on the inner peripheral surface of the third tube portion 130 to accommodate the material to be dried and transfer the material in the rotation direction of the third tube portion 130. By the third transfer member 131, the material to be dried is accommodated on the one surface side of the third transfer member 131 formed on the lower side of the third tube portion 130, and then the third tube portion 130 rotates. It rises with it and falls from the upper side of the 3 cylinder part 130. FIG. That is, due to the rotation of the third cylinder part 130, the material to be dried accommodated on one surface side of the third transfer member 131 below the third cylinder part 130 is pulled up and transferred in the rotation direction of the third cylinder part 130. Then, it falls from the upper side of the third cylindrical portion 130. Here, in order to easily accommodate the material to be dried on one surface side of the third transfer member 131, the third transfer member 131 may have a bent flat plate shape or a curved plate shape. This is the same as 121.

  In addition, the third transfer member 131 also has an inclination angle so that the object to be dried is transferred along the direction approaching the discharge port (o) from the input port (i) while being rotated by the third cylindrical portion 130.

  However, since the transfer direction of the object to be dried in the third cylinder part 130 is opposite to the transfer direction of the object to be dried in the second cylinder part 120, the third transfer member 131 is opposite to the second transfer member 121. With a slope of

  The hot air part 140 provides hot air to the second cylinder part 120. The hot air unit 140 includes a hot air generating unit 141 that generates hot air and a hot air pipe 142 that is connected to the hot air generating unit 141 and is connected to the drying unit 100. The hot air pipe 142 is disposed so as to communicate with the second cylindrical portion 120.

  The hot air unit 140 is connected to a heater (not shown), a blower (not shown) and the like outside to generate hot air, and can be omitted when sunlight is sufficient.

  The hot air pipe 142 passes through a discharge portion 182 to be described later and communicates with the second tube portion 120, and is disposed below the first tube portion 110, that is, near the discharge portion (o). With such an arrangement, the hot air reaches the inside of the second cylindrical portion 120 and is discharged through the third cylindrical portion.

  Therefore, the material to be dried that is primarily transferred by the first cylindrical portion 110 is dried by hot air, and then secondarily dried again by the hot air inside the second cylindrical portion 120. Considering the whole, the time during which the material to be dried is in contact with the hot air is increased, so that the drying efficiency is improved.

  In addition, the arrangement described above has an effect of making the temperature distribution in the internal space of the first cylinder part 110, the second cylinder part 120, and the third cylinder part 130 uniform, thereby further improving the drying efficiency of the object to be dried. There is an effect to.

  Although it has been described above that air heated by mobilizing external energy including the hot air portion 140 and the like is supplied to the first tube portion 110 and the second tube portion 120, the sunlight is sufficiently strong. In this case, the hot air unit 140 is not necessary, but the recirculation unit 190 sucks and discharges a gas (g) such as water vapor and gas generated from an object to be dried in the drying process through a blower fan, Is recirculated to the first tube portion 110. Since this gas (g) is in a state of being heated by solar heat, the temperature is higher than that of the outside air even without the hot air generator 141. It is therefore sufficient to recharge for drying the material to be dried.

  As shown in FIGS. 1 to 5, the roller 150 provides rotational force to the first cylinder part 110, the second cylinder part 120, and the third cylinder part 130. Such a roller 150 is disposed on the upper surface of the horizontal frame 160 and meshes with a protruding portion 132 formed on the outer peripheral surface of the third cylindrical portion 130.

  The roller 150 is connected to a motor (not shown) or the like. Therefore, when the motor is turned on and the roller 150 rotates, the third cylindrical portion 130 rotates together. In addition, as described above, since the third cylindrical portion 130 is connected to the second cylindrical portion 120 and the first cylindrical portion 110 is connected to the connecting member 122, when the roller 150 rotates, the second cylindrical portion 120 and the first cylindrical portion 110 are connected. The tube portion rotates together.

  The horizontal frame 160 is disposed horizontally on the floor surface where the continuous rotary solar dryer according to the present invention is installed. In such a horizontal frame 160, a vertical frame 170 and a discharge unit 182 described later are respectively connected to the upper surface, and the roller 150 described above is disposed between the vertical frame 170 and a discharge unit 182 described later.

  An empty space is formed inside the horizontal frame 160, and can accommodate a material to be dried that has finished the drying process discharged from the discharge unit 182 described below.

  The vertical frame 170 supports the third cylinder portion 130. Accordingly, the vertical frame 170 is connected to the upper surface of the horizontal frame 160 and is connected to the end portion of the third cylindrical portion 130 so as to support the third cylindrical portion 130.

  The exhaust unit 181 discharges a gas (g) such as water vapor or gas generated from the object to be dried after drying.

  The discharge unit 182 is connected to the end of the third tube unit 130 so as to support the third tube unit 130, and the third tube unit 130 is configured to discharge the material to be dried after the drying process to the horizontal frame 160. To be supplied with the material to be dried.

  In the exhaust part 181, the air that has passed through the first cylinder part, the second cylinder part 120, and the third cylinder part 130 is exhausted to the blower part 190 described later, and the gas (g) exhausted from the exhaust part 181 is also included. It is discharged to the blower 190.

  On the other hand, a particulate removal unit 500 is provided between the blower unit 190 and the exhaust unit 181 and receives the supply of gas (g) generated by drying the hot air and the object to be dried. It can also be removed. Here, the particulate removal unit may be provided by a cyclone or the like.

  A part of the gas discharged from the blower 190 is discharged to the outside, and the other part is transferred again to the first tube part 110 via the exhaust gas circulation part 183.

  Such a blower unit 190 reuses a gas having a higher temperature than the outside air to increase the contact time with the object to be dried, resulting in a continuous rotating sun according to an embodiment of the present invention. The drying efficiency of the light dryer 1000 can be improved.

  Therefore, according to the continuous rotary solar dryer according to the embodiment of the present invention described above, the volume of the dryer is greatly reduced, and the object to be dried can be generated by natural sunlight without additional energy supply. Can be dried.

  Further, it may further include a drying means 400 that can preliminarily dry an object to be dried using exhaust gas discharged in communication with the air blowing unit 190 described above. It can be said that the drying means 400 can be provided in a different type, and various types of drying means are all possible. In this description, an exemplary mold drying means will be described. The non-die drying means 400 includes the non-stick 410 provided in multiple stages, and the lower part of the drying means 410 and the exhaust part 181 are provided in communication with each other. Flow into. The inflowing exhaust gas moves to the upper side of the drying means 400, and the material to be dried is preliminarily dried and discharged to the outside.

  Further, a sterilization lamp (not shown) may be provided inside the drying unit, preferably the second cylindrical unit 120 and the third cylindrical unit 130, to improve the sterilization and flavor of the object to be dried.

  As shown in the above-described drawings, the material to be dried is introduced into the charging unit 200, and the material to be dried is moved to the inside of the first cylindrical part 110 via the transfer pipe 210 and the charging port (i). At this time, when the motor 230 is rotated, the transfer screw 220 connected to the motor 230 is rotated, and the material to be dried is transferred in the direction of the first tube portion 110.

  Subsequently, when the first cylinder part 110 rotates, the material to be dried moves from the inlet (i) of the first cylinder part 110 to the outlet (o) side by the action of the first transfer member (111). Thus, it is primarily dried by the sunlight that reaches the inside of the first tube portion 110. At this time, the object to be dried comes into contact with the gas (g) that has flowed in again through the blower 190, and is secondarily dried. Since the discharge port (o) of the first cylinder part 110 is open, the material to be dried falls into the internal space of the second cylinder part 120.

  Thereafter, the object to be dried is transferred along the second cylinder part 120, and the second cylinder part 120 that has received the transmission of the rotational force by the roller 150 part rotates, so that the substance to be dried inside the second cylinder part 120 is dried. The object rotates in the rotation direction of the second cylindrical portion 120. At this time, the object to be dried is transferred in a direction approaching the charging port (i) of the first cylinder part 110 by the inclined second transfer member 121 formed on the inner peripheral surface of the second cylinder part 120. Further, it is further dried by sunlight transmitted through the third cylinder part 130 and the second cylinder part 120.

At this time, the object to be dried is transferred in a direction approaching the discharge port (o) by the inclined third transfer member 131 formed on the inner peripheral surface of the third cylindrical portion 130, and at the same time, the final object is caused by the above-described sunlight. Dry.

  Therefore, the transfer path (drying path) of the object to be dried in the internal space from the first cylinder part 110 to the third cylinder part 130 is increased by the primary, secondary, and tertiary drying processes described above. Therefore, the volume of the continuous rotary solar dryer 1000 can be significantly reduced, and at the same time, the time during which the material to be dried contacts with sunlight is increased, and the drying efficiency is increased. Moreover, since the temperature gradient of the 1st cylinder part 110, the 2nd cylinder part 120, and the 3rd cylinder part 130 becomes uniform by arrange | positioning the hot air piping 142, the whole of the multistage rotating solar hot air dryer 1000 is performed. This has the effect of increasing the drying efficiency.

Be transported. At this time, the gas (g) that reaches the end portion of the third cylindrical portion 130 together with the material to be dried is discharged to the exhaust portion 181.

  At this time, a part of the dust-removed gas (g) described above is discharged to the outside by the air blowing part 190 communicated with the exhaust part 181, and the remaining part flows into the first cylinder part 110 and is covered by the above-described object. Recirculate according to the movement of the dry matter and the drying process. Of course, if the hot air unit 140 can additionally input heat energy from the outside in this process, the drying effect can be further increased.

  Thereafter, the material to be dried transferred to the discharge cylinder 182 is transferred to the internal space of the horizontal frame 160, and the drying process is finally finished.
