Description

Technical Field

[0001] The utility model relates to the field of drying equipment, in particular to a mesh belt type dynamic drying room. Background Art

[0002] Traditional crop drying methods, such as natural air drying, are incapable of dealing with the problem of easy mildew, difficulty in drying and storage of crops after harvest. This traditional method is not only time-consuming, but also causes losses due to the easy mildew of crops. In order to achieve better drying effect, drying devices are proposed in the prior art.

[0003] Among them, a static drying device is provided in the prior art. This type of hot air drying device is provided with an air inlet and an air outlet. The fan blows hot air into the drying chamber at the air inlet. The hot air passes through the interior of the drying chamber and dries the agricultural materials on the drying rack. The dried air flows out from the air outlet. However, in this type of structure, the flow field distribution in the drying chamber is difficult to be uniform, and the material is in one position without changing, resulting in uneven drying of the material at each point, and the required drying time is relatively long.

[0004] The prior art also provides a dynamic drying device, which drives a transmission belt through an electric motor to perform hot air drying on a dynamic drying rack. However, after one round of material drying, the material cannot completely reach the required target moisture content, and a circulating return device is required to return the material to complete the cyclic drying of the material. During operation, the material starts to be fed from the top layer of the conveyor belt. As the conveyor belt keeps running, when it reaches the last layer, the material is sent back to the first layer through the circulating return device until it is dried to a safe moisture content. Although this device solves the problem of uneven drying to a certain extent, it also brings the problem of high energy consumption. Utility Model Content

The discharging extrusion mechanism includes an active discharging roller 19, a driven discharging roller 20, a first sprocket 41, a second sprocket 42, a third sprocket 43, a fourth sprocket 44, a transmission chain 50 and a spring 49. The first sprocket 41 is rotatably mounted on the first frame 8 through a first rotating shaft 45. A second vertical slide groove is provided on both front and rear sides of the lower part of the first frame 8. A second slider is slidably installed in each second vertical slide groove. A second bearing is provided in each second slider. The fourth sprocket 44 is rotatably mounted in two second bearings through a fourth rotating shaft 48. The upper end of the spring 49 is gap-sleeved on the fourth rotating shaft 48, and the lower end is fixed on the first frame 8. The fourth sprocket 44 is located below the first sprocket 41.

[0052] The active discharging roller 19 is rotatably mounted on the first frame 8 via the second rotating shaft 46. The setting height of the active discharging roller 19 is lower than the setting height of the first sprocket 41 and higher than the setting height of the fourth sprocket 44. The second sprocket 42 is fixedly sleeved on one end of the second rotating shaft 46. The first power drive mechanism is used to provide power to the discharging extrusion mechanism. Specifically, the first power drive mechanism also includes a first active sprocket, a first driven sprocket and a first chain. The first active sprocket is fixedly sleeved on the power output shaft of the first motor 22, and the first driven sprocket is fixedly sleeved on the other end of the second rotating shaft 46. The first chain is wound around the first active sprocket and the first driven sprocket. When the first motor 22 is working, it can drive the second rotating shaft 46 to rotate, thereby rotating the active discharging roller 19.

[0053] A horizontal slide groove is provided on both the front and rear sides of the lower part of the first frame 8, a third slider is slidably installed in each horizontal slide groove, a third bearing is provided in each third slider, the driven discharge roller 20 is rotatably installed in the two third bearings through the third rotating shaft 47, the third sprocket 43 is fixedly sleeved on one end of the third rotating shaft 47, the driven discharge roller 20 is located on the side of the active discharge roller 19 away from the first sprocket 41, the transmission chain 50 is wound around the first sprocket 41, the third sprocket 43 and the fourth sprocket 44, and the second sprocket 42 is located on the outside of the transmission chain 50 and contacts with the transmission chain 50.

[0054] The discharging conveying mechanism includes a fourth active roller, a fourth driven roller, a discharging conveyor belt 21 and a fourth motor. The fourth active roller is rotatably installed in the drying room 1 through a fourth active wheel shaft. The fourth driven roller is rotatably installed in the drying room 1 through a fourth driven wheel shaft. The discharging conveyor belt 21 is wound around the fourth active roller and the fourth driven roller. The discharging end of the discharging conveyor belt 21 can extend to the outside through the discharging port. The power output shaft of the fourth motor is connected to the fourth active wheel shaft, and the fourth motor is connected to the controller.

[0055] In this embodiment, the discharge end of the lowermost mesh belt conveyor mechanism is located above the gap between the active discharge roller 19 and the driven discharge roller 20, and the discharge conveyor belt 21 is located below the gap between the active discharge roller 19 and the driven discharge roller 20.

[0056] When discharging, the first motor 22 drives the active discharging roller 19 to rotate, and the first sprocket 41, the third sprocket 43 and the fourth sprocket 44 are rotated through the second sprocket 42 and the transmission chain 50, and then the driven discharging roller 20 is rotated. When the material is discharged downward from the bottom conveyor mesh belt 9, the material passes through the gap between the active discharging roller 19 and the driven discharging roller 20, and the driven discharging roller 20 slides toward the side away from the active discharging roller 19, and the fourth rotating shaft 48 moves upward. After the discharging is completed, the driven discharging roller 20 is no longer squeezed by the material, and the fourth rotating shaft 48 is reset under the tension of the spring 49, and the driven discharging roller 20 also returns to its position to prevent hot air leakage.

[0057] like Figure 8 As shown, in order to determine whether the discharge extrusion mechanism operates smoothly, it is necessary to calculate the wrap angle of the active discharge roller 19. The calculation formula is as follows based on this implementation case:

[0058] β2=360°-ε1-ε2-δ2

[0059]

[0060] Wherein β1, β2, β3, β4 are the wrap angles of the first sprocket 41, the second sprocket 42, the third sprocket 43, and the fourth sprocket 44, respectively. a1 is the center distance between the first sprocket 41 and the second sprocket 42, a2 ​​is the center distance between the second sprocket 42 and the third sprocket 43, a3 is the center distance between the third sprocket 43 and the fourth sprocket 44, and a4 is the center distance between the fourth sprocket 44 and the first sprocket 41. The first sprocket 41, the second sprocket 42, the third sprocket 43, and the fourth sprocket 44 have the same pitch circle diameter, which is represented by d. The first sprocket 41, the second sprocket 42, the third sprocket 43, and the fourth sprocket 44 select the same pitch circle radius of 100 mm.

[0061] Among them, a1=436mm, a2=300mm, a3=650mm, and then the wrap angle β2 of the second sprocket 42 is solved to be 124°, which meets the working requirements of the sprocket transmission and can operate smoothly.

[0062] The power required by the first motor 22 is calculated using this embodiment.

[0063] To calculate the power required for the operation of the mesh belt drying bed, it is first necessary to calculate the power P of a single-layer conveyor mesh belt 9. The power of a single-layer conveyor mesh belt 9 is:

[0064] P=FV

[0065] Where F is the total load force of the driving roller of the single-layer conveyor mesh belt 9, N; V is the moving speed of the conveyor mesh belt 9, m / s;

[0066] The total load force F is calculated as follows:

[0067] F=G2×(LD) / D

[0068] G2=9.8×(G+q0l)

[0069] Where G2 is the total gravity of the material and the conveyor mesh belt 9, N; L is the moving distance of alfalfa on the conveyor mesh belt 9, m; l is the total length of the mesh belt, m; D is the diameter of the active roller, mm; G is the mass of the material, kg; q0 is the self-weight per unit length of the conveyor mesh belt 9, kg / m.

[0070] Where G is 30kg, q0=4.5kg / m, L=3.2m, l=6.7m, D=100mm, V=0.05m / s, and the above specific values ​​are substituted into the formula to obtain G2=589.5N, F=18275N. Therefore, the power of the single-layer conveyor belt 9 is calculated to be P=913.8W, and the total power P0 of the four-layer conveyor belt 9 is about 3655W. The motor is worn during use, and the power loss rate is k=0.32. The rated power of the required motor is P e , so the required rated power of the motor is calculated

[0071] The required power P1 of the discharge extrusion mechanism is:

[0072] P1=F1V1

[0073] F1=p0×A×K×μ

[0074]

[0075] Where F1 is the tangential force of the active discharge roller 19, N; V1 is the linear speed of the active discharge roller 19, m / s; p0 is the contact pressure between the material and the active discharge roller 19, Pa; A is the contact area between the material and the active discharge roller 19, m 2 ; K is the contact coefficient; μ is the friction coefficient; n is the rotation speed of the active discharge roller 19, r / min; r is the radius of the active discharge roller 19.

[0076] Take r = 0.25m, n = 200r / min, and calculate the speed

[0077] Take p0=0.714Mpa, A=0.007m, K=0.6, μ=0.2, and calculate P1=0.5kW.

[0078] Therefore, a 7.5kW electric motor can be selected to meet the working requirements of the first motor 22 .

[0079] In this embodiment, hot air enters from the air inlet 3 at the lower left side, and is evenly introduced into the mesh belt drying bed area through the air distribution chamber 2 uniform wind device, and finally is discharged through the air outlet 7 above the drying room 1. The feeding device is on the right side of the drying room 1. After the material enters the horizontal conveyor belt 16, the material leveling mechanism can flatten the material to a certain thickness, and then transport it to the inside of the drying room 1. After staying in the mesh belt drying bed for a period of time, the discharge conveyor belt 21 will send the material that reaches the target moisture content out from the discharge port at the lower right of the drying room 1.

[0080] In this specific embodiment, the first motor 22, the second motor 28, the third motor 31 and the fourth motor are all adjustable speed motors. The first sensing component 51 is a first photoelectric sensor, and the second sensing component is a second photoelectric sensor.

[0081] In this embodiment, a heat-insulating layer is provided on the inner wall of the drying room 1. The heat-insulating layer is preferably made of polyurethane foam material. In order to further reduce heat loss, the thickness of the heat-insulating layer is set to 80 mm to 100 mm.

[0082] The uniform wind device includes a plurality of first baffles 5 and a plurality of second baffles 6. The plurality of first baffles 5 are sequentially arranged on a side close to the air inlet 3 in the vertical direction. The first baffle 5 includes a horizontal plate and a first curved plate. One end of the horizontal plate is fixed on the side wall of the air distribution chamber 2 where the air inlet 3 is arranged. The upper part of the other end of the horizontal plate is provided with a first curved plate. The length of the horizontal plate of the plurality of first baffles 5 decreases from bottom to top, and the width of the plurality of first baffles 5 is the same. The plurality of second baffles 6 are sequentially arranged on a side away from the air inlet 3 in the horizontal direction. The lower end of the second baffle 6 is arranged on the bottom surface of the air distribution chamber 2. The width of the plurality of second baffles 6 increases from one end close to the air inlet 3 to one end away from the air inlet 3. The plurality of second baffles 6 have the same height, and the second baffle 6 is a second curved plate. The uniform wind device in this embodiment allows the hot air to flow evenly into the upper part of the drying room 1, so that the material is evenly heated, the drying effect is optimized, and the cost and energy consumption of the drying material are reduced, and the drying efficiency is improved.

[0083] In this embodiment, two first baffles 5 are provided, and four second baffles 6 are provided.

[0084] The drying energy method in this embodiment is solar energy-heat pump combined drying. The solar flat-plate collector collects solar radiation to heat the air. The hot air flows from the ventilation duct to the condenser in the drying room 1. A forward blower is installed at the air inlet 3 to increase the wind speed to heat the air, and then the hot air is input into the drying room 1 through the air inlet 3.

[0085] The air outlet 7 is provided with an induced draft fan, which is connected to a controller and can speed up the wind flow in the drying room 1, so that the hot air passes through the material on the mesh belt drying bed, and the hot air can better take away the moisture of the material. In this embodiment, two air outlets 7 are provided.

[0086] Specifically, in order to verify whether the hot air in the drying room 1 can pass through multiple layers of materials in the vertical blowing mode, alfalfa is taken as an example and a ventilation test is carried out in combination with the existing drying box device.

[0087] The layout of air permeability test points is as follows: Fig.10As shown, the wind speed sensors are arranged in four layers, each layer is arranged at the position directly opposite the air outlet, and two wind speed sensors are set on each layer. From bottom to top, the two test points of the first layer are X1 and X2, the two test points of the second layer are X3 and X4, the two test points of the third layer are X5 and X6, and the two test points of the fourth layer are X7 and X8. The temperature and humidity sensors are arranged on the three-layer mesh tray where the materials are placed. From near to far from the top air outlet, they are the upper layer, the middle layer, and the lower layer. The communicator records the wind speed measured by the wind speed sensor every 5 seconds, and the final wind speed data is the average wind speed within 10 minutes. Table 1 is the wind speed table of each test point under load when the outlet is installed with an induced draft fan, and Table 2 is the wind speed table of each test point under load exhaust when the outlet is installed with an induced draft fan.

[0088] Table 1. Wind speed table at each test point with load

[0089]

[0090] Table 2: Wind speed table at each test point under load ventilation

[0091]

[0092] like Fig.11 and Fig.12 As shown in the figure, under the normal vertical blowing load test, the hot air passes through multiple layers of alfalfa, and the hot air loss is relatively serious. After adding the induced draft fan, the wind speed between the layers of mesh plates is significantly improved. Comparing the changes in the moisture content of each layer of alfalfa during normal vertical blowing and the changes in the moisture content of each layer of alfalfa after adding the induced draft fan, it is found that the moisture content of each layer of alfalfa decreases greatly during normal vertical blowing, and the drying time is longer. After adding the induced draft fan, the drying of each layer of alfalfa is relatively uniform and the drying time is shortened. It is verified that in the drying room 1 after adding the induced draft fan, the hot air can pass through the alfalfa layer during vertical blowing, accelerating the drying time of alfalfa.

[0093] This embodiment also provides an intermittent dynamic drying process based on a mesh belt type dynamic drying room, comprising the following steps:

[0094] Step 1. The material is transported to the feed end of the top mesh belt conveyor mechanism through the feeding device. As the first power drive mechanism drives, when the first sensing component 51 on the side of the discharge end of the top mesh belt conveyor mechanism detects the material, it means that the material covers the top mesh belt conveyor mechanism. The first power drive mechanism and the feeding device both stop working and dry for a period of time t1.

[0095] Specifically, the material to be dried is put into the storage bin 13, and under the drive of the second motor 28, the inclined conveyor belt 14 drives the conveyor belt baffle 15 to operate, and the conveyor belt baffle 15 clamps the material and lifts it to the horizontal conveyor belt 16; after the material is transported to the horizontal conveyor belt 16, the third motor 31 drives the horizontal conveyor belt 16 and the central axis 18 to start rotating, and the material is leveled at the leveling mechanism, and the material that does not meet the thickness requirement is pushed backward. When the material at the back accumulates to a certain thickness, it is recognized by the second sensing component, and the operation of the inclined conveyor belt 14 is stopped, and the horizontal conveyor belt 16 continues to transport the material into the drying room 1.

[0096] Step 2, the first power drive mechanism and the feeding device are both reopened, and the material falls from the top mesh belt conveyor mechanism onto the mesh belt conveyor mechanism adjacent to the top mesh belt conveyor mechanism, and when the first sensing component 51 on the discharge end side of the mesh belt conveyor mechanism adjacent to the top mesh belt conveyor mechanism detects the material, it indicates that the material fills the mesh belt conveyor mechanism adjacent to the top mesh belt conveyor mechanism, and the first power drive mechanism and the feeding device both stop working. The time required to fill the mesh belt conveyor mechanism adjacent to the top mesh belt conveyor mechanism is t2, and t2 is 1min~5min. After drying for a period of time t1, the first power drive mechanism and the feeding device are both reopened; and so on, the material is filled in multiple mesh belt conveyor mechanisms in turn and dried for a period of time t1; the number of mesh belt conveyor mechanisms is m, and m*t1 is 120min~180min.

[0097] Step three, the mesh belt conveyor mechanism at the bottom moves for a period of time t2, so that the dried material falls into the discharge device from the discharge end of the mesh belt conveyor mechanism at the bottom and is transported to the outside through the discharge port. After each drying period t1, the mesh belt conveyor mechanism moves for a period of time t2.

[0098] This example takes alfalfa as the research object, and studies the time that a 10cm thick alfalfa layer stays on each conveyor belt under the test conditions of a temperature of 55℃ and a wind speed of 6m / s. First, a 10cm thick alfalfa layer is placed in a drying room 1 for drying, and the time for alfalfa to dry to a safe moisture content (17% and below) at different detection points is 120min~180min. According to this time divided by the number of mesh belt conveyor mechanisms n, a range is obtained, which provides a reference for the drying time of each layer of mesh belt conveyor mechanisms in subsequent experiments. Because the mesh belt drying bed adopts a four-layer mesh belt conveyor mechanism, and the rate of decrease of the moisture content of alfalfa under dynamic drying is faster than that of static drying, the residence time of alfalfa on each layer of mesh belt conveyor mechanisms is set to 20min, 30min, and 40min. The experiment determines the moisture content by the change in the mass of alfalfa. After the alfalfa stays on each layer of mesh belt conveyor mechanism for 20min, the material is discharged on the last layer, and the moisture content is 35%, which does not reach the safe moisture content. After alfalfa stays on each layer of the mesh belt conveyor for 30 minutes, it is discharged on the last layer with a moisture content of 21%. When alfalfa stays on each layer of the mesh belt conveyor for 40 minutes, it is discharged on the last layer with a moisture content of 15%. Therefore, it can be adjusted between 30 minutes and 40 minutes to meet the process requirements. The same operation is performed for other materials.

[0099] The comparison effect between the intermittent dynamic drying process used in this embodiment and the traditional static drying process and dynamic cycle drying process is as follows.

[0100] Test conditions: hot air temperature 55°C, air inlet speed 4.5m / s, material thickness 7cm.

[0101] Test results: The time for static drying to reach the target moisture content is 180 minutes, and the energy consumption is 13kwh. The time for the intermittent dynamic drying process to reach the target moisture content is 140 minutes, and the energy consumption is 12kwh. The dynamic cycle drying process uses three transmission speeds. The first transmission speed is 0.02m / s, the time is 140 minutes, and the energy consumption is 17kwh; the second transmission speed is 0.04m / s, the time is 120 minutes, and the energy consumption is 17.5kwh; the second transmission speed is 0.08m / s, the time is 110 minutes, and the energy consumption is 19kwh.

[0102] It can be seen that the energy consumption of the intermittent dynamic drying process is not much different from that of the static drying process, but the drying time is shortened by 2 / 9. Compared with the dynamic cycle drying process, the intermittent dynamic drying process has a similar drying time when the conveyor belt movement speed is low, saving 1 / 4 of the energy consumption; when the conveyor belt speed is high, the drying time of the intermittent dynamic drying process is slightly longer than that of the dynamic cycle drying process, but it has obvious advantages in terms of energy consumption.

[0103] In this embodiment, an intermittent dynamic drying process is adopted to achieve the target moisture content of the material in the mesh belt drying bed at one time. Compared with the dynamic drying device, there is no need to match the circulating return device, which reduces energy consumption. Compared with the static drying device, the material is dried evenly and the drying time is reduced, that is, while ensuring high work efficiency, energy consumption is reduced and the uniformity of material drying is ensured.

[0104] This specification uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, according to the idea of ​​the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
