[0015] In summary, the present application includes at least one of the following beneficial technical effects: 1. The red dates in the present application fall from the feed port onto the conveyor belt of the spiral tower conveyor, and then the red dates roll downward along the conveyor belt of the spiral tower conveyor under the action of gravity, and the hot air blower in the present application is located below the conveyor belt of the spiral tower conveyor, so the hot air blown by the hot air blower will dry the red dates on the conveyor belt of the spiral tower conveyor from bottom to top, and because the heat energy of the hot air will be consumed in the process of moving from bottom to top, the temperature of the space above the conveyor belt of the spiral tower conveyor will be lower than the temperature of the space below the conveyor belt of the spiral tower conveyor, so when the conveyor belt of the spiral tower conveyor moves During the process, the temperature it is subjected to will gradually increase, thereby achieving the effect of preheating first and then drying, and the equipment for preheating and drying in this embodiment is completed by a hot air blower, which does not require additional equipment to complete, so the energy consumption and floor space required for the entire equipment will be reduced; at the same time, since the spiral tower conveyor in the present application is vertical, the volume of the equipment in the lateral direction is relatively small, and the floor space will also be smaller; in addition, the energy source for preheating the red dates in the present application is also the residual heat left after the hot air blower dries the red dates, which greatly improves the utilization of energy and further reduces energy consumption; 2. In the present application, the conveyor belt of the spiral tower conveyor moves from a low position to a high position, so the moving direction of the conveyor belt of the spiral tower conveyor is opposite to the moving direction of the red dates on its surface. On the one hand, it can increase the travel distance and residence time of the red dates on the conveyor belt of the spiral tower conveyor, so the preheating or drying time of the red dates by the hot air blower is longer, thereby improving the drying effect of the red dates by the present device; on the other hand, the moving direction of the red dates is opposite to the moving direction of the conveyor belt of the spiral tower conveyor, so the red dates and the surface of the conveyor belt of the spiral tower conveyor are prone to relative sliding and rolling, so that the red dates can make each surface of itself face downward during the rolling process, and because the hot air moves from bottom to top, each surface of the red dates can be in the most direct contact with the hot air, so that the red dates themselves are evenly preheated or dried, thereby improving the drying effect of the present device on the red dates; 3. The setting of the pushing component. On the one hand, the pushing component can move the red dates on the spiral tower conveyor belt along the width direction of the spiral tower conveyor belt to avoid the accumulation of red dates on one side of the spiral tower conveyor belt as much as possible, thereby spreading the red dates on the spiral tower conveyor belt on the surface of the spiral tower conveyor belt, increasing the contact area between the red dates and the hot air, thereby further improving the preheating or drying effect of the equipment on the red dates; on the other hand, the staggered setting of multiple pushing components makes some of the red dates on the spiral tower conveyor belt present an S-shaped moving path on the surface of the conveyor belt. Compared with the moving path along the length direction of the spiral tower conveyor belt, the S-shaped moving path is longer, thereby further increasing the travel distance and residence time of the red dates on the spiral tower conveyor belt, and the preheating or drying time of the red dates by the hot air blower is longer, thereby further improving the drying effect of the equipment on the red dates.

DETAILED DESCRIPTION
[0017] The following is combined with Figure 1-6 , further details of this application are given.
[0018] An energy-saving drying equipment for dates, referring to Figure 1 , Figure 2 and Figure 3 , including a shell 1, a spiral tower conveyor 2 and a hot air blower 3.
[0019] The shell 1 in this embodiment is configured to be cylindrical, a feed port 11 is disposed on the upper end surface of the shell 1 , and a discharge port 12 is disposed on the peripheral wall of the shell 1 .
[0020] The spiral tower conveyor 2 is coaxially located inside the housing 1. A conveyor belt 23 is provided on the spiral tower conveyor 2. The uppermost conveyor belt 23 of the spiral tower conveyor 2 is located below the feed port 11. The lowermost conveyor belt 23 of the spiral tower conveyor 2 is located at the discharge port 12. The conveyor belt 23 of the spiral tower conveyor 2 in this embodiment is configured as a metal mesh (not shown in the figure). The gap spacing between the metal meshes is smaller than the diameter of the red dates. The inner and outer sides of the conveyor belt 23 of the spiral tower conveyor 2 are both configured There is a guard plate 24 to prevent the red dates from falling from the conveyor belt 23 of the spiral tower conveyor 2 as much as possible, and the conveyor belt 23 of the spiral tower conveyor 2 in this embodiment moves from a low place to a high place. It should be noted that the slope of the conveyor belt 23 of the spiral tower conveyor 2 in this embodiment has been specifically designed so that the red dates on the conveyor belt 23 of the spiral tower conveyor 2 can overcome the friction force applied by the conveyor belt 23 to the red dates, so that they can continue to move in the opposite direction of the movement of the conveyor belt 23 under the action of gravity.
[0021] The hot air blower 3 in the present embodiment is coaxially located in the shell body 1 and is located below the spiral tower conveyor 2. The hot air blower 3 in the present embodiment is designed as a cylinder as a whole. The upper end face of the hot air blower 3 is provided with a ring-shaped air outlet. The air outlet of the hot air blower 3 is located directly below the conveyor belt 23 of the spiral tower conveyor 2, and the width of the air outlet of the hot air blower 3 is the same as the width of the conveyor belt 23 of the spiral tower conveyor 2. It is located below the conveyor belt 23 of the spiral tower conveyor 2, so as to efficiently dry the red dates on the conveyor belt 23 of the spiral tower conveyor 2.
[0022] When the red dates need to be dried, the hot air blower 3 is started first. Since the air outlet of the hot air blower 3 is located at the bottom of the shell 1 and the density of hot air is lower than that of air, the hot air will move from the bottom of the shell 1 to the top of the shell 1. As the hot air loses heat energy during its rising process, the temperature of the upper space in the shell 1 will be lower than the temperature of the lower space in the shell 1.
[0023] After the hot air blower 3 is turned on for a period of time, the red dates are poured into the feed port 11 on the shell 1, and then the red dates fall on the conveyor belt 23 at the uppermost end of the spiral tower conveyor 2. Since the slope of the conveyor belt 23 is specially designed, the component of the gravity acting on the red dates in parallel to the surface of the conveyor belt 23 is greater than the friction acting on the red dates. Therefore, the red dates can still move downward along the surface of the conveyor belt 23. Therefore, the temperature of the space in which the red dates on the conveyor belt 23 of the spiral tower conveyor 2 are gradually increased during the descent. Therefore, when the red dates fall from the feed port 11 onto the conveyor belt 23 of the spiral tower conveyor 2, the red dates are located in the upper part of the shell 1 and will first undergo a preheating stage. As the red dates continue to move downward, the temperature to which the red dates are subjected will become higher and higher. When the red dates reach the lower part of the shell 1, the red dates begin to undergo a drying stage and are finally discharged from the discharge port 12 of the shell 1.
[0024] Since red dates have a biological protection reaction, if the red dates directly enter a high-temperature drying environment at room temperature, the huge temperature difference will cause the biological protection reaction of the red dates, causing the pores of the epidermal cells to shrink and the hard shell to harden, which will prevent the evaporation of moisture inside the red dates and affect the drying effect. In this embodiment, the red dates will undergo a preheating stage and a drying stage, which can make the temperature to which the red dates are subjected change uniformly, thereby improving the drying efficiency of the red dates and ensuring the quality of the dried red dates as much as possible. In addition, the temperature in the shell 1 in this embodiment rises steadily from top to bottom. Compared with the traditional use of multiple drying devices, the temperature change amplitude is smaller, so the biological protection reaction of the red dates is smaller, thereby further improving the drying efficiency of the red dates and ensuring the quality of the dried red dates as much as possible.
[0025] At the same time, the equipment for preheating and drying in the present embodiment is completed by the hot air blower 3. Compared with the existing layered multi-stage drying method, the present equipment does not need to add additional drying equipment and conveying equipment to complete the process. Therefore, the energy consumption and floor space required for the entire equipment in the present embodiment will be reduced. In addition, since the spiral tower conveyor 2 in the present application is vertical, the volume of the equipment in the lateral direction is relatively small, and the floor space will also be smaller. In the present application, the energy source for preheating the red dates is also the waste heat remaining after the hot air blower 3 dries the red dates, which greatly improves the utilization of energy and further reduces energy consumption.
[0026] In addition, in the present application, the conveyor belt 23 of the spiral tower conveyor 2 moves from a low place to a high place, so the moving direction of the conveyor belt 23 of the spiral tower conveyor 2 is opposite to the moving direction of the red dates on its surface. On the one hand, it can increase the travel distance and residence time of the red dates on the conveyor belt 23 of the spiral tower conveyor 2, so the preheating or drying time of the red dates by the hot air blower 3 is longer, thereby improving the drying effect of the red dates by the present device; on the other hand, the moving direction of the red dates is opposite to the moving direction of the conveyor belt 23 of the spiral tower conveyor 2, so the red dates and the surface of the conveyor belt 23 of the spiral tower conveyor 2 are prone to relative sliding and rolling, so that the red dates can make each surface of itself face downward during the rolling process, and because the hot air moves from bottom to top, each surface of the red dates can be in the most direct contact with the hot air, so that the red dates themselves are evenly preheated or dried, thereby improving the drying effect of the present device on the red dates.
[0027] Reference Figure 2 and Figure 4 The spiral tower conveyor 2 in this embodiment mainly includes a column 21 and a support frame 22.
[0028] The column 21 is coaxially arranged with the shell 1, and a plurality of support frames 22 are provided. The plurality of support frames 22 are spirally arranged around the column 21, and the axis of each support frame 22 is perpendicular to the axis of the column 21. The conveyor belt 23 is installed on the support frame 22, and the guard plates 24 on both sides of the conveyor belt 23 are installed on the support frame 22. The conveyor belt 23 and the guard plates 24 are both arranged downward along the spiral, wherein a driving roller 25 is rotatably provided on the support frame 22, and the driving roller 25 is connected to the conveyor belt 23. A driving motor 26 for driving the driving roller 25 to rotate is also provided on the support frame 22. When the driving motor 26 drives the driving roller 25 to rotate, the driving roller 25 drives the conveyor belt 23 to move in a bottom-to-top direction. The spiral tower conveyor 2 is a prior art and will not be described in detail here.
[0029] Among them, in this embodiment, multiple pushing assemblies 4 are evenly spaced on both sides of the conveyor belt 23 of the spiral tower conveyor 2, and the pushing assemblies 4 on the inner and outer sides of the conveyor belt 23 of the spiral tower conveyor 2 are also evenly spaced along the length direction of the conveyor belt 23, and the pushing assemblies 4 on the inner and outer sides of the conveyor belt 23 of the spiral tower conveyor 2 are also staggered and not on the same plane, and the output directions of the multiple pushing assemblies 4 are perpendicular to the moving direction of the conveyor belt 23 of the spiral tower conveyor 2.
[0030] Reference Figure 4 and Figure 5 The push assembly 4 in this embodiment includes an electric push rod 41 and an elastic block 42.
[0031] The electric push rod 41 is fixedly mounted on the guard plate 24, and the elastic block 42 is fixedly mounted on the output shaft of the electric push rod 41. The output direction of the electric push rod 41 is perpendicular to the moving direction of the conveyor belt 23 of the spiral tower conveyor 2. A plurality of make way grooves (not shown in the figure) are provided on the guard plates 24 on both sides of the conveyor belt 23 of the spiral tower conveyor 2. The plurality of make way grooves correspond to the plurality of pusher components 4 one by one. The plurality of electric push rods 41 will extend or contract synchronously under the control of the program. When the electric push rod 41 extends, it drives the elastic block 42 to move along a position close to the center of the conveyor belt 23. The elastic block 42 will push the red dates on the surface of the conveyor belt 23 during the movement, thereby avoiding the situation where the red dates are piled up on one side of the conveyor belt 23 as much as possible. The red dates on the conveyor belt 23 of the spiral tower conveyor 2 are spread flat on the surface of the conveyor belt 23 of the spiral tower conveyor 2, thereby increasing the contact area between the red dates and the hot air, thereby further improving the preheating or drying effect of the device on the red dates; at the same time, the multiple pushing components 4 are staggeredly arranged, so that part of the red dates on the conveyor belt 23 of the spiral tower conveyor 2 presents an S-shaped moving path on the surface of the conveyor belt 23. Compared with the moving path along the length direction of the conveyor belt 23 of the spiral tower conveyor 2, the S-shaped moving path is longer, thereby further increasing the travel distance and residence time of the red dates on the conveyor belt 23 of the spiral tower conveyor 2, and the preheating or drying time of the red dates by the hot air blower 3 is longer, thereby further improving the drying effect of the device on the red dates.
[0032] The end of the elastic block 42 that faces away from the moving direction of the red dates is set as an arc surface, which can guide the red dates away from the elastic block 42 to avoid the accumulation of red dates due to the obstruction of the elastic block 42 as much as possible; at the same time, the elastic block 42 in this embodiment has a certain elasticity, so that when the elastic block 42 hits the red dates, the impact effect of the elastic block 42 on the red dates is reduced, thereby avoiding the damage of the red dates as much as possible.
[0033] In the present embodiment, a material guide pipe 5 is provided at the feed port 11 on the shell 1. The material guide pipe 5 in the present embodiment is connected with the feed port 11, and the material guide pipe 5 is arranged in a flat shape. The material guide pipe 5 is close to the guard plates 24 on both sides of the conveyor belt 23 of the spiral tower conveyor 2. Therefore, when the red dates enter the shell 1 from the feed port 11, the material guide pipe 5 can guide the red dates to the conveyor belt 23 relatively stably, and try to avoid the situation that the red dates deviate and do not fall on the conveyor belt 23.
[0034] Reference Figure 5 and Figure 6, one end of the guide pipe 5 close to the conveyor belt 23 is also provided with two guide rollers 51, the two guide rollers 51 are arranged opposite to each other and rotatably mounted on the inner wall of the guide pipe 5, one end of the two guide rollers 51 passes through the tube wall of the guide pipe 5, and are coaxially fixedly connected with a first gear 52 and a second gear 53 respectively, the first gear 52 and the second gear 53 are meshed, and a rotating motor 54 is fixedly arranged on the support frame 22, and the output shaft of the rotating motor 54 is coaxially fixedly connected with the first gear 52, and the distance between the two guide rollers 51 can only allow one red date to pass through, so the guide pipe 5 can quantitatively lead the red dates to the conveyor belt 23, so as to avoid uneven accumulation of red dates on the conveyor belt 23, resulting in uneven drying of the red dates, thereby causing the quality of the red dates to be reduced; at the same time, the two guide rollers 51 can rotate towards each other under the drive of the rotating motor 54, so there is no need to worry that the red dates will block the space between the two guide rollers 51.
[0035] In addition, in the present embodiment, the outer peripheral walls of the two guide rollers 51 are provided with soft bristles (not shown in the figure). The provision of the soft bristles can not only reduce the wear on the red dates when the guide rollers 51 rotate, but also wipe the surface of the red dates, thereby wiping off the moisture on the surface of the red dates, thereby further accelerating the evaporation of moisture on the surface of the red dates, and to a certain extent, also accelerating the drying efficiency of the red dates by the present equipment.
[0036] Reference Figure 2 The shell 1 is divided into a preheating zone and a drying zone according to the upper and lower spaces. Both the preheating zone and the drying zone are provided with a temperature detection component 6. The temperature detection component 6 is electrically connected to the hot air blower 3. In this embodiment, the temperature detection component 6 is configured as a temperature sensor. The temperature sensor and the hot air blower 3 are electrically connected to the control center.
[0037] Since the preheating temperature and drying temperature of the red dates are both within a certain range, when the temperature sensor detects that the temperature inside the shell 1 is too high, the control center will reduce the output power of the hot air blower 3, so as to try to avoid the situation where the temperature is too high and the red dates are baked to a crisp; similarly, when the temperature sensor detects that the temperature inside the shell 1 is too low, the control center will increase the output power of the hot air blower 3, so as to try to avoid the situation where the red dates are not completely dried by this device.
[0038] Reference Figure 2 and Figure 3 In this embodiment, a hot air circulation component 7 is also provided on the shell 1, and the hot air circulation component 7 includes a guide pipe 71 and a pump 72. One end of the guide pipe 71 extends into the shell 1 from the top of the shell 1, and the other end of the guide pipe 71 bends from the outside of the shell 1 to the bottom of the shell 1, and then extends into the shell 1 and is connected with the hot air blower 3. A pump 72 is also provided on the guide pipe 71.
[0039] When the hot air blown by the hot air blower 3 reaches the upper space in the shell 1, the hot air will enter the guide tube 71, and then the pump 72 will draw the hot air through the guide tube 71 to the bottom of the shell 1, and then enter the hot air blower 3. Since the air in the space located in the upper part of the shell 1 has already dried and preheated the red dates, it may have some residual heat left. At this time, this part of the air is again guided into the hot air blower 3, and then the hot air blower 3 will continue to heat up this part of the air for continued use. Since this part of the air still retains some residual heat, the energy consumed by the hot air blower 3 when heating this part of the air will be reduced, thereby further reducing energy consumption and waste as a whole.
[0040] Since there will be residual moisture in the air after the red dates are dried and preheated, a dehumidification component 8 is also provided in the guide tube 71 in the present embodiment. The dehumidification component 8 in the present embodiment is configured as a water-absorbing film. The water-absorbing film in the present embodiment is made of a water-absorbing resin, which has good water absorption or water retention. At the same time, it also has certain air permeability. Therefore, after the hot air carrying moisture passes through the water-absorbing film, it can absorb and preserve the moisture in the hot air, so that the air re-enters the hot air blower 3 as dry gas, so as to ensure that the hot air blown out from the hot air blower 3 is dry gas as much as possible, thereby ensuring the drying effect of the red dates as much as possible.
[0041] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
