Description

Technical Field

[0001] This utility model relates to the field of grain drying technology in grain storage, and in particular to a grain storage corn seed and ear drying device. Background Technology

[0002] Grain warehouses are specialized buildings used to store large quantities of grain. To reduce the moisture content of corn seeds and ears, prevent mold and rot, and ensure the safe storage and quality of corn seeds and ears, drying equipment is needed to dry them. In the grain warehouse, heated gas is used to directly contact the corn seeds and ears, and the heat is transferred to the corn seeds and ears by convection, causing the moisture in the corn seeds and ears to vaporize, thereby achieving the purpose of drying.

[0003] There are still some problems in the use of existing grain drying equipment in grain warehouses. Currently, the industry commonly uses electric heating tubes for heating and dehumidification. This heating system uses electricity or coal, which is relatively energy-intensive and not environmentally friendly. Air source heat pumps are a highly efficient, environmentally friendly technology that utilizes free heat energy in the air. Through a heat pump system, it consumes a small amount of electricity to drive a fan, concentrating the small amount of heat energy widely present in the air and converting it into heat energy that can be used by humans. It is one of the important technological directions for replacing traditional fossil fuels for heating and hot water supply. However, the use of air source heat pumps as an energy source in the seed industry is relatively limited. Even when air source heat pumps are used, they are simply used for drying corn seeds and ears. The dry heat source uses an air-source heat pump internal fan to generate hot air that passes through the corn seed and ear layer for unidirectional hot air drying. The hot air is then directly discharged, resulting in energy waste as moisture and heat are discharged simultaneously. In the corn kernel or ear dehumidification chamber, there are multiple layers of corn kernels or ears vertically. The unidirectional hot air flow causes uneven heating and humidity among the corn kernels and ears that come into contact with the hot air first, resulting in uneven moisture content among the seeds. This prevents all seeds from reaching the standard moisture content, thus affecting seed quality. Therefore, those skilled in the art provide a corn seed and ear drying device for grain storage to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grain storage corn seed and ear drying device. By opening the first electric gate and closing the second air door, and adjusting the first air door, air is allowed to enter the grain storage cylinder from the top, facilitating the delivery of hot air from the top for drying. This prevents uneven heating and humidity of the seeds, ensuring that all seeds reach the standard moisture content, thus affecting seed quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grain storage corn seed and ear drying device, comprising a seed storage chamber and a storage top, wherein the storage top is located at the upper end of the seed storage chamber, and multiple drying structures are arranged in a front-to-back pattern at the lower center of one side wall of the seed storage chamber;

[0006] Taking the drying structure described earlier as an example, the drying structure includes a warehouse, which is located on one side wall of the seed storage compartment. An air-source heat pump is installed on the inner side wall of the warehouse away from the seed storage compartment. The input end of the air-source heat pump is fixedly connected to three ventilation doors. One of the input ends of the three ventilation doors passes through the inner side wall of the warehouse and leads to one side of the warehouse. The output end of the air-source heat pump is fixedly connected to a fan. The output end of the fan is fixedly connected to a first damper. The two output ends of the first damper are respectively fixedly connected to a first pipe and a second pipe. The first pipe and the second pipe pass through the inner side wall of the warehouse and one side wall of the seed storage compartment in sequence and lead to the interior of the seed storage compartment. The ends are fixedly connected to a grain storage hopper. A support is fixedly connected to the lower part of the interior of the grain storage hopper. A plate screen is fixedly connected to the upper end of the support.

[0007] The above technical solution involves activating the air-source heat pump, opening the three ventilation doors connecting the inlet to the outside of the warehouse, and closing the three ventilation doors inside the warehouse. The air-source heat pump draws in air from the outside and dries and heats it using its built-in dehumidification and heating function. The dried air is then transported by a fan to the first damper, which in turn transports the hot air into the second pipe. From there, the hot air is transported into the grain storage silo, blown onto the grain through a screen, and finally, the second electric damper is opened. Hot air is discharged from the second electric gate for drying. By controlling the gate connecting the first damper and the first pipeline to open and the gate connecting the first damper and the second pipeline to close, hot air is transported through the first pipeline to the upper part of the grain storage hopper. The second electric gate is closed, allowing air to pass through the grain and enter the lower part of the grain storage hopper. The first electric gate is opened, allowing hot air to be discharged into the warehouse. This prevents uneven heating and humidity of the seeds, ensuring that all seeds reach the standard moisture content, thus affecting seed quality.

[0008] Furthermore, a second damper is fixedly connected to the end face of the first pipeline away from the seed storage compartment;

[0009] The above technical solution involves opening the second air door to allow air to be transported into the warehouse, then closing the valves connecting the three ventilation doors to the outside, and opening the gates of the three ventilation doors inside the warehouse. This allows the heated air inside the warehouse to be dehumidified by the air-source heat pump, then reheated, and circulated into the grain storage silo through the fan and the first pipe. This reduces the power output of the air-source heat pump and reduces energy consumption.

[0010] Furthermore, a second electric gate is fixedly connected to the center of the upper end face of the grain storage silo on the side near the warehouse.

[0011] Through the above technical solution, during the drying process, the second electric gate is closed to prevent hot air from being released and thus avoiding waste.

[0012] Furthermore, the upper end face of the support is inclined, the bottom end of the support is located on the side away from the warehouse, and a discharge gate is fixedly connected to one side wall of the grain storage hopper on the bottom side of the upper end face of the support.

[0013] The above technical solution allows grain to be discharged through a discharge gate.

[0014] Furthermore, the second pipe output end is located on one side of the support, slightly lower.

[0015] The above technical solution facilitates the smooth passage of hot air through the sieve for drying the grain.

[0016] Furthermore, a first electric gate is fixedly connected to the lower center of the grain storage hopper near the side wall of the warehouse. The output end of the first electric gate passes through the inner wall of the grain storage hopper and the side wall of the warehouse in sequence, leading to the inner wall of the warehouse.

[0017] By using the above technical solution, the first electric gate is opened, allowing hot air to be discharged into the warehouse through the first electric gate.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the grain drying equipment in the grain warehouse opens the first electric gate, closes the second air door, and adjusts the first air door to allow air to enter the grain storage cylinder from the top, which facilitates the delivery of hot air from the top for drying. This prevents uneven heating and humidity of the seeds, ensuring that all seeds reach the standard moisture content, thus affecting the quality of the seeds.

[0020] 2. In this utility model, the hot air is re-entered into the warehouse through the second air door on the drying structure after the second electric gate is closed. Then, the input end is connected to the warehouse through the three ventilation doors. The air heat pump removes the water vapor in the hot air and then delivers it to the grain storage silo again, thereby reducing energy consumption. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1-4 One embodiment of this utility model is a grain storage corn seed and ear drying device, which includes a seed storage compartment 1 and a storage top 3. The storage top 3 is located at the upper end of the seed storage compartment 1, and multiple drying structures 2 are arranged in a front-to-back arrangement at the lower center of one side wall of the seed storage compartment 1.

[0030] like Figure 1 , 2As shown in Figures 3 and 4, taking the drying structure 2 at the front as an example, the drying structure 2 includes a storage room 201, which is located on one side wall of the seed storage compartment 1. An air source heat pump 204 is installed on the inner side wall of the storage room 201 away from the seed storage compartment 1. The input end of the air source heat pump 204 is fixedly connected to a three ventilation door 214. One of the input ends of the three ventilation doors 214 passes through the inner side wall of the storage room 201 and extends to one side of the storage room 201. A fan 205 is fixedly connected to the output end of the air source heat pump 204. The output end of the blower 205 is fixedly connected to the first damper 206. The two output ends of the first damper 206 are respectively fixedly connected to the first pipe 207 and the second pipe 209. The first pipe 207 and the second pipe 209 pass through the inner side wall of the warehouse 201 and the side wall of the seed warehouse 1 to the interior of the seed warehouse 1. The ends are fixedly connected to the grain storage cylinder 202. The lower part of the inside of the grain storage cylinder 202 is fixedly connected to the support 203. The upper end of the support 203 is fixedly connected to the plate screen 210.

[0031] By activating the air source heat pump 204, the gate connecting the input end of the three ventilation dampers 214 to the outside of the storage room 201 is opened, while the gate of the three ventilation dampers 214 inside the storage room 201 is closed. The air source heat pump 204 draws in air from the outside of the storage room 201 and dries and heats the outside air using its built-in dehumidification and heating function. The heated and dried air is then transported by the fan 205 to the first damper 206, through which the hot air is transported to the inside of the second pipe 209. The hot air is then transported to the inside of the grain storage hopper 202 through the second pipe 209, and finally blown onto the grain through the plate screen 210. Finally, the second electric gate 21 is opened. 3. Hot air is discharged from the second electric gate 213 for drying. By controlling the gate connecting the first damper 206 and the first pipe 207 to open, and the gate connecting the first damper 206 and the second pipe 209 to close, hot air is transported through the first pipe 207 to the upper part of the grain storage hopper 202. The second electric gate 213 is closed, allowing air to pass through the grain and enter the lower end of the grain storage hopper 202. The first electric gate 212 is opened, allowing hot air to be discharged into the warehouse 201 through the first electric gate 212. This prevents uneven heating and humidity of the seeds, ensuring that all seeds reach the standard moisture content, thus affecting the quality of the seeds.

[0032] A second damper 208 is fixedly connected to the end face of the first pipe 207 away from the seed storage chamber 1. When the second damper 208 is opened, air is transported through the second damper 208 into the storage chamber 201. Then, the valve of the three ventilation damper 214 connected to the outside is closed, and the gate of the three ventilation damper 214 inside the storage chamber 201 is opened. The heated air inside the storage chamber 201 is then dehumidified by the air source heat pump 204, reheated, and circulated into the grain storage hopper 202 through the fan 205 and the first pipe 207. This reduces the power output of the air source heat pump 204 and reduces energy consumption.

[0033] A second electric gate 213 is fixedly connected to the center of the upper end of the grain storage silo 202 on the side near the warehouse 201. During the drying process, the second electric gate 213 is closed to prevent hot air from being released and wasted.

[0034] The upper surface of the support 203 is inclined, and the bottom end of the support 203 is located on the side away from the warehouse 201. A discharge gate 211 is fixedly connected to one side wall of the grain storage hopper 202 on the bottom side of the upper surface of the support 203, and the grain is discharged through the discharge gate 211.

[0035] The output end of the second pipe 209 is located on the lower side of the support 203, which facilitates the smooth passage of hot air through the grain on the plate screen 210 for drying.

[0036] A first electric gate 212 is fixedly connected to the lower center of the side wall of the grain storage silo 202 near the warehouse 201. The output end of the first electric gate 212 passes through the inner wall of the grain storage silo 1 and the side wall of the warehouse 201 and connects to the inner wall of the warehouse 201. When the first electric gate 212 is opened, hot air is discharged into the warehouse 201 through the first electric gate 212.

[0037] Working principle: When in use, by starting the air source heat pump 204, the gate connecting the input terminal of the three ventilation doors 214 to the outside of the warehouse 201 is opened, while the gate of the three ventilation doors 214 inside the warehouse 201 is closed. The air source heat pump 204 draws in air from the outside of the warehouse 201. Through the dehumidification and heating function of the air source heat pump 204, the outside air is dried and heated. During the operation of the air source heat pump 204, the surface temperature of the evaporator is lower than the dew point temperature of the air, causing water vapor in the air to condense into water, thereby achieving the purpose of dehumidification. The air source heat pump 204 absorbs heat from the air through the evaporator. The refrigerant evaporates in the evaporator and becomes a low-temperature, low-pressure gas. The compressor compresses the low-temperature gas into a high-temperature, high-pressure gas. The high-temperature, high-pressure gas releases heat in the condenser to heat the circulating water or air. The expansion valve throttles and reduces the pressure of the high-pressure gas, which is then circulated back to the evaporator. This is a common dehumidification and heating technology of existing air source heat pumps 204, and will not be elaborated further here.

[0038] After being heated and dried, the air is transported by the fan 205 to the first damper 206. The hot air is then transported through the first damper 206 to the second pipe 209, and then through the second pipe 209 to the grain storage silo 202. The hot air is then blown onto the grain through the plate screen 210. The second electric gate 213 is then opened, and the hot air is discharged from the second electric gate 213 for drying. During the drying process, the second electric gate 213 is closed and the second damper 208 is opened, allowing the air to be transported to the warehouse 201 through the second damper 208. The valve connecting the three ventilation doors 214 to the outside is then closed, and the gate of the three ventilation doors 214 inside the warehouse 201 is opened. The heated air inside the warehouse 201 is then dehumidified by the air source heat pump 204, reheated, and then circulated into the grain storage silo 202 through the fan 205 and the first pipe 207. This reduces the power output of the air source heat pump 204 and reduces energy consumption.

[0039] Then, by controlling the gate connecting the first damper 206 and the first pipe 207 to open, and the gate connecting the first damper 206 and the second pipe 209 to close, hot air is transported through the first pipe 207 to the upper part of the grain storage hopper 202. The second electric gate 213 is closed, allowing air to enter the lower end of the grain storage hopper 202 after passing through the grain. The first electric gate 212 is opened, allowing hot air to be discharged into the warehouse 201 through the first electric gate 212. This prevents uneven heating and humidity of the seeds, ensuring that all seeds reach the standard moisture content, thus affecting the quality of the seeds.

[0040] Then, the valve connecting the three ventilation doors 214 to the outside is closed, and the gate of the three ventilation doors 214 inside the warehouse 201 is opened. This allows the heated air inside the warehouse 201 to be dehumidified by the air source heat pump 204, then reheated, and circulated into the grain storage hopper 202 through the fan 205 and the first pipe 207. This reduces the power output of the air source heat pump 204 and reduces energy consumption.

[0041] Temperature and humidity sensors are installed inside the warehouse 201 and the grain storage silo 202 to monitor the air temperature and humidity in real time. A programmable logic controller is used to control the various valves, fans 205 and air source heat pump 204. The operating status of the equipment is adjusted according to the data fed back by the sensors. During the circulating heating stage, the power output of the air source heat pump 204 is appropriately reduced to reduce power consumption while ensuring the drying effect. This is a commonly used technical means in existing control systems and will not be elaborated on here.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
