[0039] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0040] Example 1

[0041] In the related art, the upper and lower augers will wear out after a period of use, which is not only difficult, time-consuming and costly to replace, but the long augers will also increase the breakage rate of grains. The hot air temperature used by the dryer is relatively high, which can dry feed or corn in one go, and the drying efficiency is relatively high, but the drying uniformity is poor, and the drying adaptability for heat-sensitive grains such as rice is relatively low.

[0042] The researchers of this application found that after the materials to be dried are dried by the drying equipment, there is a situation where the drying time is long or the moisture content of the materials after drying does not meet the storage standard, which affects the drying efficiency and drying effect of the materials to be dried.

[0043] refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides a drying device 100 , which includes at least one drying chamber 110 , a first air duct assembly 120 , a material feeding assembly 130 , a plurality of material guides 140 and a first fan assembly 150 .

[0044] Specifically, combined Figures 2 to 4As shown, the drying bin 110 is provided with a ventilation hole 111, a feed port 112 and a discharge assembly 113, the discharge assembly 113 is arranged at one end of the drying bin 110, and the discharge assembly 113 is provided with a first discharge port 1131 and a second discharge port 1132; the first air duct assembly 120 is connected to the drying bin 110 through the ventilation hole 111; the feed assembly 130 includes a feed pipe 131, one end of the feed pipe 131 is connected to the feed port 112 of the drying bin 110, and the feed pipe 131 is away from the feed port 112. One end of the material port 112 is connected to the second material outlet 1132, and at least part of the feed pipe 131 is passed through the first air duct assembly 120; the material guide 140 is arranged in the drying bin 110, and one material guide 140 is arranged at one of the ventilation holes 111; the first fan assembly 150 is arranged at one end of the first air duct assembly 120 away from the material port 112, and accordingly, the material to be dried enters the material port 112 of the drying bin 110 through the feed pipe 131 of the feed assembly 130, and at least part of the feed pipe 131 is passed through the first air duct assembly 120. In the first air duct assembly 120, the feed pipe 131 is arranged at the position of the first air duct assembly 120 to improve the space utilization rate, and the drying chamber 110 is connected with the first air duct assembly 120 and the outside of the drying chamber 110 through the ventilation hole 111. The material guide 140 in the drying chamber 110 can make the hot air in the first air duct assembly 120 enter the drying chamber 110 and take away the water vapor in the drying chamber 110. The first fan assembly 150 is arranged at one end of the first air duct assembly 120 to accelerate the air flow in the first air duct assembly 120 and accelerate the heat exchange in the drying chamber 110 to ensure the heat exchange of the first air duct assembly 120. To ensure that there is sufficient drying temperature in the drying bin 110 and improve the drying effect, the drying operation is performed on the material to be dried in the drying bin 110. The material guide 140 can also reduce the disturbance and influence of the wind flow at the position of the ventilation hole 111 during the falling process of the material to be dried in the drying bin 110, thereby ensuring the normal falling path of the material to be dried. The material guide 140 plays a guiding and protective role for the material to be dried. After falling, the material to be dried can enter the feed pipe 131 again through the second discharge port 1132, so as to facilitate the cyclic drying of the material to be dried when the moisture content of the material does not meet the standard.

[0045] Combination Figures 2 to 4 As shown, the drying device 100 has a first direction X, a second direction Y and a third direction Z, wherein the first direction X, the second direction Y and the third direction Z are arranged vertically in pairs. Exemplarily, the first direction X is taken as the length direction of the drying device 100, the second direction Y is taken as the width direction of the drying device 100, and the third direction Z is taken as the height direction of the drying device 100. It can be understood that the above definition is only for the convenience of understanding the relative position relationship of each part in the drying device 100, and should not be understood as a limitation to the present application.

[0046] Exemplarily, the feed pipe 131 of the feed component 130 is arranged along the third direction Z, that is, the height direction of the feed pipe 131 and the drying device 100 are parallel to each other. The feed component 130 includes a hoist to facilitate lifting the material in the feed pipe 131 by the hoist, and then the material falls freely in the drying bin 110 under the action of gravity to dry the material.

[0047] In one embodiment, optionally, Figure 6 As shown, the multiple ventilation holes 111 are respectively arranged on the opposite sides of the drying chamber 110, the ventilation holes 111 on the side close to the first air duct component 120 are air inlet holes 1111, and the ventilation holes 111 on the side away from the first air duct component 120 are air outlet holes 1112. In other words, the air inlet holes 1111 and the air outlet holes 1112 are relatively arranged, and the hot air in the first air duct component 120 enters the drying chamber 110 through the air inlet holes 1111, and heat exchange is completed in the drying chamber 110. The airflow then takes away the water vapor in the drying chamber 110 through the position of the air outlet holes 1112, and the entire airflow flow channel will not be blocked or affected, so that the hot air flow path of the drying chamber remains in a flow state.

[0048] Optionally, refer to Figure 1 and Figure 2 As shown, the number of the drying bins 110 is two, and the first air duct assembly 120 is arranged between the two drying bins 110, so that the air inlet holes 1111 of the two first air duct assemblies 120 are arranged opposite to each other, that is, when the two drying bins 110 are respectively located at opposite ends of the first air duct assembly 120, the air inlet holes 1111 of the two drying bins 110 are arranged opposite to each other. In addition, multiple drying bins 110 are arranged around the first air duct assembly 120 so that the hot air in the first air duct assembly 120 can enter the drying bin 110. Multiple drying bins 110 can improve the drying efficiency, and multiple drying bins 110 can be connected in parallel to dry at the same time to meet the situation of drying more materials.

[0049] Of course, there can be more than one drying bin 110 , and the multiple drying bins 110 can be unloaded through the reversing pipe 133 , so that when the multiple drying bins 110 are used together, the feeding time and the discharging time can be reduced, thereby improving the material discharging efficiency.

[0050] Exemplarily, the material in the drying bin 110 enters the first discharge port 1131 or the second discharge port 1132 through the discharge hopper 1133, and the material in the discharge hopper 1133 can enter the first discharge port 1131 or the second discharge port 1132 through the material blocking member, so as to realize the discharge switching between the first discharge port 1131 or the second discharge port 1132. When the material enters the second discharge port 1132, it can enter the feed assembly 130 through the second discharge port 1132, and the material can be lifted in the feed pipe 131 by the lifting member 132. Finally, the material can enter different drying bins 110 through the reversing pipe 133, wherein the discharge hopper 1133 is a conical structure, so as to facilitate the discharge of the discharge hopper 1133. It can be understood that the reversing pipe 133 can be a reversing tee pipe, which can improve the discharge efficiency of the material, thereby improving the drying efficiency, and is used to change the flow direction of the material or fluid in the pipeline system. Its design incorporates three ports that can select one of two different flow paths through an internal mechanism (such as a ball, flapper or plug), thus enabling the ability to switch delivery routes without interrupting the process.

[0051] In addition, the drying bin 110 includes a slow drying section, an expansion section and a drying section. The expansion section is located above the slow drying section. The expansion section is used to shake and level the grain materials. The slow drying section is used to allow the materials to rest during the drying process. No drying and heating treatment is performed in the slow drying section. The slow drying section allows the moisture inside the grain to diffuse from the high moisture area to the low moisture area through capillary action, which helps to improve the uniformity of the final drying. For grains that are prone to bursting, such as rice, the bursting phenomenon caused by rapid drying of the outside while the internal moisture is still high, that is, expansion damage, can be reduced. The drying section is located at the bottom of the slow drying section and the expansion section. The ventilation holes 111 and the material guide 140 are both arranged in the drying section to facilitate heating and drying of the grain materials and improve the drying effect.

[0052] Alternatively, if Figure 5 and Figure 7 As shown, a part of the multiple material guide members 140 is the first material guide member 141, and another part of the multiple material guide members 140 is the second material guide member 142. The first material guide member 141 is located on the side of the second material guide member 142 close to the discharge assembly 113. In other words, the type of the material guide member 140 can be the first material guide member 141 or the second material guide member 142. Both the first material guide member 141 and the second material guide member 142 can guide the material in the drying bin 110, and also reduce the disturbance and influence of the wind flow entering the drying bin 110 on the falling path of the material.

[0053] Based on any of the above embodiments, Figure 5 and Figure 7As shown, the cross-section of the material guide member 140 is a V-shaped structure, and the opening direction of the material guide member 140 of the groove structure is set on the side away from the feed port 112. Since the opening direction of the material guide member 140 is not towards the direction of the feed port 112, the hot air will not directly blow towards the material falling through the feed port 112 when entering the drying bin 110, thereby reducing the disorder of the material's falling path causing the material to fly out through the vent, ensuring that the material's falling path remains unchanged. The material guide member 140 with a V-shaped cross-section guides the airflow to reduce the wind resistance of the airflow, reduce the noise generated by the airflow, increase the heat exchange area, and improve the drying effect.

[0054] In one embodiment, optionally, reference Figure 6 As shown, the drying device 100 also includes a second fan assembly 160, which is connected to one end of the first air duct assembly 120 away from the first fan assembly 150. Accordingly, the second fan assembly 160 is connected to the first air duct assembly 120 through a pipeline, and the second fan assembly 160 is installed on the upper part of the drying device 100.

[0055] In summary, the drying device 100 allows the material to be dried to enter the feed port 112 of the drying bin 110 through the feed pipe 131 of the feed component 130, at least part of the feed pipe 131 is arranged in the first air duct component 120, and the feed pipe 131 is arranged at the position of the first air duct component 120 to improve the space utilization rate, and the drying bin 110 is connected with the first air duct component 120 and the outside of the drying bin 110 through the ventilation hole 111, and the material guide 140 in the drying bin 110 can make the hot air in the first air duct component 120 enter the drying bin 110 and take away the water vapor in the drying bin 110, and the first fan component 150 is arranged at one end of the first air duct component 120 to accelerate the air flow in the first air duct component 120 and accelerate the drying The heat exchange in the drying bin 110 ensures that there is a sufficient drying temperature in the drying bin 110, thereby improving the drying effect. The drying operation is performed on the material to be dried in the drying bin 110. The material guide 140 can also reduce the disturbance and influence of the wind flow at the ventilation hole 111 during the falling process of the material to be dried in the drying bin 110, thereby ensuring the normal falling path of the material to be dried. The material guide 140 plays a guiding and protective role for the material to be dried. After falling, the material to be dried can enter the feed pipe 131 again through the second discharge port 1132, so that when the moisture content of the material does not meet the standard, the material to be dried can be cyclically dried until the moisture content of the material meets the standard, thereby ensuring that the material has better drying quality and improving the drying efficiency.

[0062] In one embodiment, optionally, Figure 6 As shown, a plurality of ventilation holes 111 are respectively arranged on opposite sides of the drying chamber 110, the ventilation holes 111 on the side close to the first air duct component 120 are air inlet holes 1111, and the ventilation holes 111 on the side away from the first air duct component 120 are air outlet holes 1112. In other words, the air inlet holes 1111 and the air outlet holes 1112 are relatively arranged, and the hot air in the first air duct component 120 enters the drying chamber 110 through the air inlet holes 1111, and heat exchange is completed in the drying chamber 110. The airflow then takes away the water vapor in the drying chamber 110 through the position of the air outlet holes 1112, and the entire airflow flow channel will not be obstructed or affected, so that the drying hot air flow path remains in a flow state.

[0063] Optionally, refer to Figure 1 and Figure 2 As shown, there are two drying chambers 110, and the first air duct assembly 120 is disposed between the two drying chambers 110, so that the air inlet holes 1111 of the two first air duct assemblies 120 are disposed opposite to each other, that is, when the two drying chambers 110 are respectively located at opposite ends of the first air duct assembly 120, the air inlet holes 1111 of the two drying chambers 110 are disposed opposite to each other. In addition, a plurality of drying chambers 110 are disposed around the first air duct assembly 120, so that the hot air in the first air duct assembly 120 can enter the drying chamber 110.

[0064] Alternatively, if Figure 5 and Figure 7 As shown, a part of the multiple material guide members 140 is the first material guide member 141, and another part of the multiple material guide members 140 is the second material guide member 142. The first material guide member 141 is located on the side of the second material guide member 142 close to the discharge assembly 113. In other words, the material guide member 140 can be the first material guide member 141 or the second material guide member 142. Both the first material guide member 141 and the second material guide member 142 can guide the material in the drying bin 110, and also reduce the disturbance and influence of the wind flow entering the drying bin 110 on the falling path of the material.

[0065] In one embodiment, optionally, Figure 7 As shown, along the first direction X, the cross-sectional areas of the plurality of first material guide members 141 gradually decrease, and the cross-sectional area of ​​the first material guide member 141 at the ventilation hole 111 is the largest, that is, the cross-sectional area of ​​the first material guide member 141 gradually decreases in the direction away from the ventilation hole 111, so that the hot air in the first air duct assembly 120 enters into the drying chamber 110 through the ventilation hole 111. When the cross-sectional area of ​​the first material guide member 141 becomes smaller, the flow rate of the wind flow is changed, thereby accelerating the flow rate of the hot air and improving the drying effect.

[0066] Furthermore, the first material guide member 141 includes a first air inlet plate and a first air outlet plate, the maximum cross-sectional area of ​​the first air inlet plate is located at the air inlet hole 1111, and the maximum cross-sectional area of ​​the first air outlet plate is located at the air outlet hole 1112, the first air inlet plate and the first air outlet plate are staggered, the first air inlet plate is arranged toward the air inlet hole 1111, and the first air outlet plate is arranged toward the air outlet hole 1112, so that the hot air enters the drying chamber 110 under the guidance of the first air inlet plate, converges to the air outlet hole 1112 through the first air outlet plate, and flows out of the drying chamber 110, taking away water vapor and dust. The staggered first air inlet plate and the first air outlet plate can improve the uniformity of hot air drying, and has a better technical effect.

[0067] In one embodiment, optionally, reference Figure 5 As shown, a plurality of second material guide members 142 are arranged side by side and spaced apart along a second direction Y, and the second direction Y is perpendicular to the first direction X. The second material guide members 142 include a second air inlet plate and a second air outlet plate, that is, a plurality of second material guide members 142 are arranged side by side and spaced apart along the width direction of the drying device 100, and the second air inlet plate and the second air outlet plate are arranged alternately, so that the hot air is guided into the drying bin 110 through a second air inlet plate and then flows out of the drying bin 110 through a second air outlet plate, thereby increasing the air flow rate, improving the ventilation efficiency, and controlling the hot air temperature within a more reasonable range. The staggered second air inlet plates and the second air outlet plates can improve the uniformity of hot air drying, avoid the situation in which the temperature in the drying bin 110 is too high and causes the grains to burst and crack, and reduce the burst rate and crack rate of the grains.

[0068] Based on any of the above embodiments, Figure 5 and Figure 7 As shown, the cross section of the material guide 140 is a V-shaped structure, and the opening direction of the material guide 140 of the groove structure is set away from the side of the feed port 112. Since the opening direction of the material guide 140 is not toward the direction of the feed port 112, the hot air will not directly blow to the material falling through the feed port 112 when entering the drying bin 110, thereby reducing the disorder of the material's falling path causing the material to fly out through the vent, ensuring that the material's falling path remains unchanged, and the material guide 140 with a V-shaped cross section guides the airflow to reduce the wind resistance of the airflow, reduce the noise generated by the airflow, increase the heat exchange area, and improve the drying effect. Exemplarily, the cross section of the material guide 140 is a pentagonal structure, which has a better optimization effect on the wind flow. In the present application, the material guide 140 can be an angular air duct.

[0069] Alternatively, if Figure 5As shown, a material guide 114 is also provided on the side wall of the drying bin 110, and the material guide 114 guides the material to reduce the situation where the material adheres to the side wall of the drying bin 110. Exemplarily, the material guide 114 is a material guide plate, and a plurality of material guide plates are arranged side by side along the third direction Z.

[0070] In one embodiment, optionally, reference Figures 8 to 10 As shown, the first fan assembly 150 includes an air duct housing 151, at least one first fan 152 and a second fan 153, a portion of the feed pipeline 131 is arranged in the air duct housing 151, the first fan 152 is arranged on the side of the air duct housing 151 facing the first air duct assembly 120, the blowing direction of the first fan 152 and the feed pipeline 131 are parallel to each other, and a first vent 155 is provided on the side of the air duct housing 151 away from the first fan 152. The first vent 155 of the air duct housing 151 can keep the first air duct assembly 120 and the outside world in air circulation, and the first vent 155 is opposite to the first fan 152. The second fan 153 is connected to the air duct housing 151, and the second fan 153 is vertically arranged with the first fan 152. Accordingly, the first fan 152 and the second fan 153 are both air supply fans. The first fan 152 can make the hot air flow along the third direction Z toward the first air duct assembly 120, so that the hot air in the first air duct assembly 120 can enter the drying bin 110 to dry the material, and the part of the feed pipe 131 along the third direction Z is passed through the air duct housing 151, which will not affect or hinder the normal operation of the lifting member 132 in the feed pipe 131, and has a high space utilization rate. Furthermore, the first fan assembly 150 also includes a windshield 154, which is arranged between the second fan 153 and the first fan 152, so that the wind flow between the second fan 153 and the first fan 152 will not affect each other, and prevent the wind flow from being turbulent. Exemplarily, the number of the first fans 152 is three, and the three first fans 152 are arranged side by side along the second direction Y.

[0071] In addition, refer to Fig. 9 and Fig.10 As shown, the first fan assembly 150 also includes an air barrier 156, which can separate the first fan assembly 150 into multiple air inlet channels. The first vent 155 is arranged on the air barrier 156. The air barrier 156 can separate the air inlet channel and the first vent 155, so that the hot air entering the air inlet channel will not directly flow out from the first vent 155, thereby preventing heat loss.

[0072] Optionally, combined Figure 2 and Figure 3As shown, the drying device 100 also includes a second air duct component 190 and an insulation layer 170. The insulation layer 170 covers the drying chamber 110 and the first air duct component 120 and defines a closed space. The second air duct component 190 includes a first pipe 191, a second pipe 192 and a third pipe 193. One end of the first pipe 191 is connected to a side of the second fan 153 away from the air duct housing 151. A third vent 195 is provided at an end of the first pipe 191 away from the second fan 153. One end of the second pipe 192 is connected to the first pipe 191, and an end of the second pipe 192 away from the first pipe 191 is connected to the third pipe 193, so that the second vent 194 of the third pipe 193 is connected to the closed space, and the third vent 195 faces outside the closed space. In other words, on the one hand, the insulation layer 170 plays an insulating role for the drying bin 110 and the first air duct assembly 120, reduces heat dissipation, and improves drying efficiency. On the other hand, a closed space is formed in the insulation layer 170, and the hot air enters the first air duct assembly 120 through the first pipe 191 and the air duct shell 151 in sequence, and then enters the drying bin 110 through the first air duct assembly 120. After drying the material, the hot air will be discharged through the air outlet holes 1112 at both ends of the drying bin 110, and the air outlet holes 1112 are still in the closed space. The hot air discharged from the air outlet holes 1112 enters the first pipe 191 again through the third vent 195 of the third pipe 193 and mixes with the hot air, thereby realizing the recycling of the hot air, thereby forming a circulating hot air drying system for the drying device 100 through the closed space.

[0073] Further, the first pipeline 191, the second pipeline 192 and the third pipeline 193 form a three-way pipeline structure, and a heat exchanger is arranged in the first pipeline 191. Exemplarily, an inspection door is provided on the side wall of the first pipeline 191 to facilitate installation and maintenance of the heat exchanger through the inspection door. Figure 3 As shown, the height of the second vent 194 of the third pipe 193 is greater than the height of the air outlet 1112, so that the dusty and humid hot air discharged through the air outlet 1112 can undergo a natural sedimentation step, and large and medium particles of dust are settled, thereby achieving the purpose of filtering the discharged dusty and humid hot air, thereby reducing the hot air circulating through the second vent 194 and reducing the dust clogging of the circulating hot air drying system.

[0074] In this embodiment, the first pipe 191, the second pipe 192 and the third pipe 193 form a bending structure having a first bending portion and a second bending portion, so that the third pipe 193 can be located in a confined space, so that the third ventilation port 195 of the third pipe 193 can receive the hot air discharged from the air outlet 1112.

[0075] Exemplarily, an air regulating member is disposed at the position of the third vent 195 to regulate the amount of air entering the third vent 195 and the direction of the air flow. The air regulating member may be a plurality of air regulating plates disposed obliquely.

[0076] In one embodiment, optionally, reference Figure 3 As shown, the drying device 100 further includes a second fan assembly 160, which is connected to the bottom of the first air duct assembly 120. Accordingly, the second fan assembly 160 is connected to the first air duct assembly 120 through a pipeline. Exemplarily, the second fan assembly 160 includes a dehumidification fan and a circulation return fan.

[0077] In one embodiment, optionally, the drying device 100 is further provided with a conveying member, which is located below the first discharge port 1131 of the discharge assembly 113, and the conveying member is connected to the first discharge port 1131, so that the material dried by the drying device 100 can be discharged through the first discharge port 1131 to the conveying member, and then transported and transferred by the conveying member. Exemplarily, the conveying member can be a belt conveyor, which conveys and transfers the material from the first discharge port 1131 through a continuous belt structure, and has a better conveying effect. In one embodiment, optionally, as Figure 1 As shown, the drying device 100 also includes a climbing assembly 180, which is installed on the outside of the insulation layer 170 along the third direction Z. The climbing assembly 180 includes a ladder and a protective cage. The protective cage protects the workers and reduces injuries caused by accidental falls, so that the workers can climb to the top of the drying device 100 via the ladder to operate and maintain the drying device 100.
