DETAILED DESCRIPTION

[0039] The present application will now be further described in detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams and only schematically illustrate the basic structure of the present application, and thus only show the components related to the present application.

[0040] Please refer to Figures 1-13 A drying device for catfish feed production, comprising an air supply assembly for drying materials and suspending materials, a flow channel for feeding materials, a vibrating assembly for assisting the air supply assembly to suspend materials, the air supply assembly comprising an adjustable air supply assembly for pushing materials to move, a hot air assembly for drying materials, and a cold air assembly for cooling, the flow channel comprising a main flow channel and a sorting flow channel, and the inlet of the main flow channel is provided with a feed assembly with bulk material function.

[0041] In specific embodiments of the present application, the air supply assembly is located at the lower position of the flow channel. In use, the air supply assembly is mainly used for heat exchange drying of the material, and at the same time, the air supply assembly blows the material upward, and the vibration assembly is matched to make the material present in a suspended state, so that the material is dispersed to the greatest extent, the heat exchange area is increased, and the drying efficiency is improved. In the process of drying the suspended material, the air supply assembly also applies a horizontal force to the material in the direction of the rear end of the material, so that the material can move to the rear end, thereby realizing the effect of continuous drying. The vibration assembly can also prevent the material from adhering to the flow channel in cooperation with the air supply assembly to suspend the material. Specifically, since the movement of the material relies on the wind force to move backward, the material with high water content is heavy and is not easy to be pushed by the wind force, so that the drying time is longer, and the suspension height is lower. The material moves through the main flow channel to the rear end, and since the suspension height is lower, the material is closer to the air supply assembly, and the drying rate is better. The material with low water content is easy to be pushed by the wind force, and moves faster, so that the drying time is shorter, and the suspension height is higher. The material enters the sorting flow channel and moves to the rear end, and the drying rate is lower. In this way, the material with low water content is prevented from being over-dried, so that the material with high water content can stay longer for drying, and the drying effect is better. The material with low water content stays for a relatively short time, and the drying rate is relatively low, so that it can be prevented from being over-dried, thereby realizing the effect of uniform drying of the material. By adjusting the air supply assembly, the size of the horizontal wind force can be adjusted, and the control of the material movement rate can be realized, so that the device can adapt to the drying operation of different humidity materials. The hot air assembly in the air supply assembly mainly realizes the drying of the material, and the cold air assembly is used for cooling the material to prevent the high-temperature material after drying from being affected by the temperature difference outside to produce water vapor.

[0042] The hot air assembly and the cold air assembly each include a gas tank, which is fixedly arranged on the base frame 28. The top of the gas tank is fixedly provided with a shell 13.

[0043] Specifically, the gas tank of the hot air assembly is a first gas tank 3 and a second gas tank 6, and the gas tank of the cold air assembly is a third gas tank 9. The first gas tank 3, the second gas tank 6, and the third gas tank 9 are arranged side by side and are fixedly arranged on the base frame 28. The first gas tank 3 is the front end of the device, and the third gas tank 9 is the rear end of the device. After the material is fed in, it first passes above the first gas tank 3 for drying, then passes above the second gas tank 6 for drying, and finally passes above the third gas tank 9 for drying, and finally the material is discharged.

[0044] The gas tank of the hot air assembly is supplied with hot air from the hot air furnace, and the gas tank of the cold air assembly is supplied with cool air from the fan.

[0045] Specifically, the first gas tank 3 is connected with the hot blast stove through the first air inlet pipe 4, and the second gas tank 6 is connected with the hot blast stove through the second air inlet pipe 7. In use, hot air generated by the hot blast stove is sent into the first gas tank 3 and the second gas tank 6, and then discharged from the top of the first gas tank 3 and the second gas tank 6 to the shell 13 to exchange heat with the material. The third gas tank 9 is connected with the fan through the third air inlet pipe 10, and the fan inputs clean cold air into the third gas tank 9. It should be noted that the cold air in the present scheme is relatively low in temperature compared with the hot air of the hot air assembly, so that the material can be cooled without generating water vapor. The air sent by the fan to the third gas tank 9 needs to be filtered to prevent foreign matter from entering, and a purification device such as an air filter can be arranged at the air inlet of the fan.

[0046] The vibration assembly includes a vibration source and a base 5, and the base 5 is arranged at the bottom of the chassis 28, and the vibration source is arranged outside the gas tank.

[0047] Specifically, in the present scheme, the vibration source is a vibrator 8, which is fixedly arranged outside the second gas tank 6, and the base 5 includes a bottom plate and a spring, and further includes a fixed column fixedly arranged at the bottom surface of the chassis 28 and a fixed column fixedly arranged at the top surface of the bottom plate. The two ends of the spring are sleeved on the upper and lower fixed columns respectively. In use, the vibrator 8 generates vibration to drive the whole device to vibrate.

[0048] The main flow channel includes a distribution plate 18 and a flow distribution plate 15, and the distribution plate 18 is fixedly arranged at the top end of the gas tank and located at the bottom of the shell 13. The distribution plate 18 is provided with an inclined first air hole 23.

[0049] Specifically, the first air hole 23 is inclined backward, that is, when the wind flows upward from the gas tank, it forms a backward direction after passing through the first air hole 23, that is, it can exert a vertical force upward on the material and also exert a certain horizontal force backward on the material, thereby achieving the effect of pushing the material to move forward by wind power.

[0050] In use, the distribution plate 18 can play a certain bearing role. Under the synergistic action of the wind power and the vibration assembly, the material continuously jumps on the distribution plate 18, achieving the effect of suspension, so that the material does not rub against the distribution plate 18 too much during movement. Since the first air hole 23 is continuously passed by the upward wind and is always vibrating, the material will not fall through the first air hole 23 into the gas tank, and it is also not easy to cause blockage.

[0051] The flow distribution plate 15 is fixedly arranged at the inner middle part of the shell 13, and the flow distribution plate 15 is provided with an inclined second air hole 24. The channel formed between the distribution plate 18 and the flow distribution plate 15 is a main flow channel.

[0052] Specifically, the second air hole 24 is inclined in the same direction as the first air hole 23, but the angle is different, and the inclination angle of the second air hole 24 is larger. This arrangement can improve the horizontal thrust and make the material with a smaller water content above the distribution plate 15 move faster, reduce the drying time, and avoid over-drying.

[0053] In use, the material with a large water content is not high in suspension height due to its heavy weight, so it can only travel in the main flow channel during the process. Due to its heavy weight, it is also less affected by the horizontal thrust, so it moves slowly, increasing the drying time. The main flow channel is closer to the gas holder, so the heat exchange effect is better, further improving the drying efficiency, so that the material with a large water content can meet the drying requirements.

[0054] The rear end of the distribution plate 18 is provided with a discharge hopper 11, and the rear end of the distribution plate 15 is provided with a vertical plate. When the material passes between the rear end of the distribution plate 18 and the vertical plate, it will fall downward through the discharge hopper 11 for discharge.

[0055] The sorting flow channel includes a first flow channel and a second flow channel. The first flow channel includes a guide plate 14 fixedly arranged at the inner upper portion of the shell 13. The channel formed between the guide plate 14 and the distribution plate 15 is the first flow channel. The guide plate 14 is provided with a filter hole 26, and the top surface of the shell 13 is provided with an air guide assembly.

[0056] Specifically, the front end of the guide plate 14 is provided with an arc-shaped structure, and the rear end is also provided with a vertical plate. When the material passes between the vertical plate and the vertical plate of the distribution plate 15, it falls downward through the discharge hopper 11 for discharge. By arranging the arc-shaped structure of the guide plate 14, the wind at this position can be guided to move horizontally, thereby improving the horizontal wind force when the material enters the first flow channel.

[0057] The front end of the guide plate 14 protrudes from the front end of the distribution plate 15 by a portion, so that the material can smoothly enter the distribution plate 15 and pass through the first flow channel between the guide plate 14 and the distribution plate 15.

[0058] The filter hole 26 is arranged in the rear half of the guide plate 14. The filter hole 26 can achieve a filtering effect, preventing the material from being sucked away by the air guide assembly. If the material is in powder form, it can be sucked away through the filter hole 26, ensuring that the powder content of the dried material is small. The front half of the guide plate 14 is not provided with a filter hole 26 to better guide the horizontal wind, avoiding the air guide assembly from upwardly guiding the wind from the arc-shaped structure and affecting the material entering the first flow channel.

[0059] The air induction assembly comprises an air induction fan 12 fixedly arranged on the top surface of the shell 13 to induce air inside the shell 13, and the air outlet of the air induction fan 12 is connected with the cyclone dust collector through a pipeline to avoid the induced powder directly floating in the air, reduce the influence on the environment, and achieve the effect of dust removal of the material.

[0060] In use, the material with less water content is greatly affected by the air supply assembly and is suspended higher, so that the material with less water content can enter the first flow channel in the drying operation, and the material with less water content can be further accelerated to move and shorten the drying time and further reduce the risk of over-drying due to the more inclined angle of the second air hole 24 on the distribution plate 15.

[0061] The second flow channel comprises a partition plate 16 and a material hole 27 arranged on the distribution plate 15, the partition plate 16 is fixedly arranged on the distribution plate 15, and the channel between the partition plate 16 and the distribution plate 15 is the second flow channel.

[0062] The second flow channel is mainly used for the material with high water content to be dried in advance, and the weight of the material with high water content is lightened, so that the material with high water content can enter the first flow channel from the second flow channel to avoid over-drying caused by the material being dried in the main flow channel.

[0063] In use, the material with high water content enters the main flow channel to be dried, if part of the material is completely dried before being discharged, the weight of the material will be lightened, the moving speed of the material in the main flow channel will be accelerated, the suspension height of the material will be increased, then the material enters the second flow channel through the material hole 27, and then enters the first flow channel, so that the high efficiency drying of the material is reduced, and the material is prevented from being over-dried.

[0064] The adjustable air supply assembly comprises an air cylinder seat 22 arranged on the distribution plate 18 and an air supply cylinder 17 rotatably arranged on the bottom surface of the distribution plate 18, the air supply cylinder 17 is provided with an air supply opening 21, the air supply cylinder 17 is driven to rotate by the driving assembly, and the air supply cylinder 17 is supplied with air by the air pump.

[0065] Specifically, a plurality of rectangular holes are formed in the distribution plate 18, and the air cylinder seat 22 is fixedly arranged at the position of the rectangular hole, and the number of the air cylinder seat 22 is consistent with the number of the rectangular hole; a support is fixedly arranged on the bottom surface of the distribution plate 18, and the end of the air supply cylinder 17 is rotatably connected with the support, and the bottom of the air cylinder seat 22 is an arc surface which is matched with the arc surface of the air supply cylinder 17; the air supply cylinder 17 is hollow, and an opening is arranged at one end of the air supply cylinder 17, and the high-pressure connector 2 is arranged at the opening end, and the high-pressure connector 2 is connected with the pipeline and the air pump, and the air pump is used to send high-pressure air into the air supply cylinder 17, and the air enters the inside of the shell 13 from the air supply opening 21; by changing the angle of the air supply cylinder 17, the blowing angle of the air supply opening 21 can be changed, so that the effect of changing the horizontal thrust can be realized, and the advancing speed of the material can be controlled; if the moisture of the material is large, the angle of the air supply opening 21 of the air supply cylinder 17 is adjusted to be small, that is, the horizontal thrust is reduced, so that the material stays in the shell 13 for a longer time, and the effect of sufficient drying can be realized; if the moisture of the material is small, the angle of the air supply opening 21 is adjusted to be large, so that the horizontal thrust is increased, and the material stays in the shell 13 for a shorter time, so that the material is not over-dried, and the drying operation of the device can be adapted to different moisture materials.

[0066] In the scheme, the driving assembly is driven by the motor 25, the motor 25 is fixedly arranged on the outside of the air tank, the output end of the motor 25 is connected with the other end of the air supply cylinder 17, and the motor 25 is used to drive the air supply cylinder 17 to rotate, so that the effect of adjusting the angle can be realized.

[0067] The feeding assembly includes the feeding hopper 1, the bulk plate 20 and the elastic sheet 19, the bulk plate 20 is fixedly arranged at the end of the distribution plate 18, and the elastic sheet 19 is fixedly arranged at the middle part of the bulk plate 20.

[0068] Specifically, the bulk plate 20 is fixedly arranged at the front end of the distribution plate 18, the middle part of the bulk plate 20 is provided with a slope, and the slope is located at the position directly below the feeding hopper 1, so as to prevent the material input from the feeding hopper 1 from directly falling on the distribution plate 18, on the one hand, to prevent the material from directly falling to cause the distribution plate 18 to be blocked, and on the other hand, to cooperate with the vibrating assembly to scatter the material (because the wet material is easy to clump), so that the material can be scattered to realize the effect of quickly dispersing the material, quickly improve the heat exchange area, improve the drying efficiency, and at the same time, the scattered material can be more convenient to cooperate with the air supply assembly to realize the suspended state, so as to avoid the material from being accumulated at the position below the feeding hopper 1 on the distribution plate 18; under the action of the vibrating assembly, the elastic sheet 19 arranged can be greatly shaken, so as to further improve the effect of scattering the material.

[0069] Drying process: start the vibrator 8, make the whole device vibrate (because the whole device is in a vibrating state, so the connection mode between the device and the external equipment is soft connection, such as setting a rubber cylinder between the feeding hopper 1 and the feeding machine for connection, so as to realize sealed feeding while avoiding the influence of vibration on the feeding machine, and other pipeline connections can select flexible pipes with pressure bearing capacity, such as corrugated pipes or metal flexible pipes), and start the air supply assembly and the air guide assembly, then put the material from the feeding hopper 1 into the shell 13, the material will be blocked by the shrapnel 19 and the slope of the bulk material plate 20 during falling from the feeding hopper 1, and will vibrate to scatter the material, then fall on the distribution plate 18, because the first air tank 3 sends hot air upward, and the hot air will pass through the first air hole 23 during hot air sending, so the hot air entering the shell 13 moves obliquely upward, so there is a lifting force and a horizontal pushing force on the material, the pushing force direction is the rear end direction of the distribution plate 18, which realizes the suspension, heat exchange and drying of the material, and pushes the material to move backward, in the moving process, the air supply assembly can be adjusted to assist the movement of the material, avoiding the situation that the force of the first air tank 3 and the angle of the first air hole 23 cannot push the material to move, in the drying process, the material with low water content has a higher suspension height, which can be higher than the height of the flow distribution plate 15, then due to the upward movement of the hot air to the arc-shaped structure of the flow guide plate 14, combined with the guidance of the air guide assembly, the horizontal wind power at this position is sufficient, so that the material with low water content is guided into the first flow channel, because the inclination angle of the second air hole 24 is larger, the moving speed of the material in the first flow channel is faster, at the same time, because the material with low water content has a lighter weight, it is easy to be guided, reducing the residence time in the shell 13, avoiding the material with low water content being over-dried, while the material with high water content stays in the main flow channel, its height is close to the first air tank 3 and the second air tank 6, realizing the effect of efficient heat exchange, improving the drying effect, at the same time, because its weight is larger, it is less affected by the wind power guidance, the moving speed is slower, the residence time is longer, and the drying is more sufficient; after the part of the material in the main flow channel is completely dried, its weight becomes lighter, the influence of wind power guidance increases, the moving speed becomes faster, and the suspension height also becomes higher, so it can enter the second flow channel through the material hole 27, then enter the first flow channel, away from the high-efficiency heat exchange area, reducing the residence time, avoiding being over-dried; when the material moves to the upper part of the third air tank 9, it is cooled, after cooling, it moves to the rear end of the distribution plate 18 and then enters the discharge hopper 11, or moves to the rear end of the flow distribution plate 15 and then enters the discharge hopper 11, completing the discharge and the drying operation.In the drying process, the adjustable air supply assembly mainly assists the material to move, and the moving speed of the material can be realized by changing the angle of the air supply port 21. A humidity meter can be arranged in the discharge hopper 11 to monitor the drying degree of the material in real time. If the drying requirement is lower, the control motor 25 changes the angle of the air supply port 21, so that the material stays for a longer time, and the drying effect is improved. If there is excessive drying, the control motor 25 changes the angle of the air supply port 21, so that the material stays for a shorter time, and the excessive drying is avoided, thereby further improving the drying effect. The air supply cylinder 17 provides horizontal thrust, and because the air supply angle is different from the angle of the distribution plate 18, a certain disturbance effect can be generated, so that the material suspension can produce a larger action and disperse the material, and the heat exchange effect is further improved. When the air supply cylinder 17 adjusts the angle of the air supply port 21, the angle of the air supply port 21 is changed, and the air supply port 21 is rotated backward to increase the horizontal thrust, so that the material moving speed is increased. During the rotation process, the air cylinder seat 22 is arranged to block the air supply port 21, so that the size of the air supply port 21 is reduced, the output air pressure is increased, the air force is transmitted farther, and the better speed-up effect is realized. It should be noted that the air supply cylinder 17 located in the first air tank 3 and the second air tank 6 outputs hot air, that is, the air pump extracts the hot air generated by the hot air furnace and pressurizes it to be delivered to the corresponding air supply cylinder 17. The air supply cylinder 17 located in the third air tank 9 outputs cold air, that is, the air pump extracts the filtered natural air or low-temperature air and pressurizes it to be delivered to the corresponding air supply cylinder 17.
