Description

Technical Field

[0001] This utility model relates to the field of crop drying technology, and in particular to a central drying device for crop material piles. Background Technology

[0002] In the field of crop drying technology, crops are usually piled up after harvest (such as haystacks or baled crop stalks). If the harvested crops contain moisture, they need to be dried. However, traditional crop material piles are usually only dried on the outer layer during drying, and the heat source cannot enter the interior of the pile. This makes it easy for the center of the pile to not dry properly, resulting in insufficient drying and a lack of good drying measures in the center of the pile, which seriously affects the drying efficiency of crop material piles. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a central drying device for agricultural materials stacks, which can dry the central part of the straw stack during the drying process, thus avoiding the failure of the central part of the straw stack to dry properly and improving the drying efficiency of the straw stack.

[0004] The purpose of this utility model is achieved through the following technical solution: a central drying device for agricultural material piles, including a base, a heater, and a fan, as well as an air supply component and a drying component. The fan and heater are installed on the base, and the air outlet of the fan is connected to the air inlet of the heater. The heater is provided with multiple hot air outlets. The air supply component includes a mounting plate and at least one air supply module. Each air supply module corresponds to a hot air outlet. The air supply module consists of an exhaust fan fixed on the mounting plate and an air duct located between the hot air outlet and the exhaust fan. One end of the air duct is connected to the hot air outlet, and the other end of the air duct is connected to the air inlet of the exhaust fan. The drying component consists of a fixed pipe fixedly installed on the exhaust fan outlet, a main drying pipe inserted into the center of the agricultural material pile, and a connecting pipe connecting the fixed pipe and the main drying pipe. The main drying pipe is provided with multiple main air outlets.

[0005] The connecting pipe is a corrugated flexible hose. Both ends of the connecting pipe are threaded connectors, and the fixed pipe and the main drying pipe are provided with threaded connection grooves that mate with the threaded connectors. There are multiple air supply modules, and the exhaust fans in each air supply module are arranged independently. A traveling component is provided on the base; the traveling component can be wheeled or tracked.

[0006] A buffer chamber is located after the heater, and the buffer chamber has multiple ventilation holes, which serve as hot air outlets. The heater itself is an air heater, an electric heating device primarily used to heat gas flow. The heating element of the air heater is a stainless steel electric heating tube. The heater's inner cavity has multiple baffles (guide plates) to guide the gas flow, prolonging the gas's residence time within the cavity, thereby ensuring thorough and uniform heating and improving heat exchange efficiency. The stainless steel heating tube, the heating element of the air heater, is formed by inserting an electric heating wire into a seamless steel tube, filling the gaps with magnesium oxide powder, which has good thermal conductivity and insulation, and then shrinking the tube. When current passes through the high-temperature resistance wire, the generated heat diffuses through the crystalline magnesium oxide powder to the surface of the heating tube and is then transferred to the air being heated, achieving the heating purpose.

[0007] The main drying pipe is equipped with multiple branch drying pipes, and each branch drying pipe has multiple auxiliary air outlets. The diameter of the auxiliary air outlets is smaller than the diameter of the main air outlets. Plugs are provided at the ends of the main drying pipe and the branch drying pipes.

[0008] It should be noted that, in this application, since the air supply modules operate independently, the air output of the fan and heater is determined based on the number of exhaust fans operating in the air supply module. The maximum air output of the fan / heater is the air volume when all air supply modules operate simultaneously, and the minimum air output of the fan / heater is the air volume required when one air supply module is operating. These details will not be elaborated upon here. The fan uses an adjustable air volume fan, such as a common variable frequency fan. Furthermore, to increase the applicability of this device, while most heaters have one inlet and one outlet, this application uses multiple air supply modules, thus requiring a buffer chamber to create an independent air duct structure for each drying component. In addition, since the space between the fan and the exhaust fan is relatively enclosed, if the air volume of the fan is greater than that of the exhaust fan, it may cause the internal pressure of the device to increase, which may lead to danger in severe cases. Therefore, a pressure detection device (such as a pressure sensor in the buffer chamber) and an overflow device (an overflow valve on the buffer chamber or the fan) are installed in this space. When the pressure is too high, the pressure is released through the overflow device. This method is an existing method and will not be described in detail here.

[0009] The beneficial effects of this utility model are as follows: By setting up an air supply component, a buffer chamber is set inside the heater. The buffer chamber is equipped with an installation plate, an exhaust fan, and an air duct. The fan and the heater are connected by a connecting pipe. The heater heats the air. The main drying pipe and the branch drying pipe are inserted into the center of the haystack. The exhaust fan draws out hot air. The hot air enters the main drying pipe and the branch drying pipe through the air duct, the fixed pipe, and the telescopic flexible hose. The air outlet on the main drying pipe and the branch drying pipe is used to uniformly dry the center of the haystack, avoiding uneven drying during the drying process, improving the drying measures at the center of the haystack, reducing the probability of accidents during the drying process, and improving the drying efficiency of the haystack.

Detailed Implementation

[0012] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0013] like Figure 1-2As shown, the first embodiment of this utility model is a central drying device for agricultural material piles, including a base 1, a heater 2, and a blower 3, as well as an air supply component 4 and a drying component 5. The blower 3 and the heater 2 are mounted on the base 1, and the air outlet of the blower 3 is connected to the air inlet of the heater 2. The heater 2 is provided with multiple hot air outlets 21. The air supply component 4 includes a mounting plate 41 and an air supply module 42, and the air supply module 42 corresponds one-to-one with the hot air outlets 21. The air supply module 42 is fixed. The assembly consists of an exhaust fan 43 on the mounting plate 41 and an air duct 44 located between the hot air outlet 21 and the exhaust fan 43. One end of the air duct 44 is connected to the hot air outlet 21, and the other end of the air duct 44 is connected to the air inlet of the exhaust fan 43. The drying assembly 5 consists of a fixed pipe 51 fixedly installed on the air outlet of the exhaust fan 43, a main drying pipe 52 inserted into the center of the crop material pile, and a connecting pipe 53 connecting the fixed pipe 51 and the main drying pipe 52. The main drying pipe 52 is provided with multiple main air outlets 54.

[0014] The connecting pipe 53 is a corrugated flexible hose. Both ends of the connecting pipe 53 are threaded connectors, and the fixed pipe 51 and the main drying pipe 52 are provided with threaded connection grooves that mate with the threaded connectors. There are multiple air supply modules 42, and the exhaust fans 43 in each air supply module 42 are arranged independently. A traveling component 11 (wheels) is provided on the base 1. A buffer chamber 86 is provided behind the heater 2, and the buffer chamber 86 has multiple ventilation holes, which are the hot air outlets 21. Multiple drying branch pipes 55 are provided on the main drying pipe 52, and each drying branch pipe 55 has multiple auxiliary air outlets 56. The diameter of the auxiliary air outlets 56 is smaller than the diameter of the main air outlets 54. Example

[0015] like Figures 3-4As shown, in the second embodiment of this utility model, the number of air supply modules 42 and drying components 5 is 5, and the remaining structure is the same as in the first embodiment. In use, the base 1, i.e., the trolley, is pushed to the vicinity of the agricultural material pile (baled material pile). The main drying pipe 52 and the branch drying pipe 55 are inserted into the center of the haystack. After both the main drying pipe 52 and the branch drying pipe 55 are inserted into the center of the haystack, the blower 3, heater 2, and exhaust fan 43 are started. Air enters the heater 2 through the blower 3, and the heater 2 heats the air, making it hot air. The exhaust fan 43 in the buffer chamber 6 extracts the heated hot air. The buffer chamber 81 is made of heat-insulating material. The hot air enters the drying component 5 through the exhaust fan 43, where it is heated... After the air is discharged to the air outlets on the main drying pipe 52 and the branch drying pipe 55, it is discharged through the air outlets and dries the haystacks, allowing the haystacks to be dried evenly by heating. The buffer chamber 6 set after the heater 2 is equipped with multiple hot air outlets. Common heaters 2 usually only have one air outlet, which cannot dry multiple haystacks at the same time. By setting multiple hot air outlets, the heater 2 can be equipped with a corresponding number of main drying pipes 52 according to the number of haystacks. Multiple haystacks can be dried simultaneously through multiple main drying pipes 52 and multiple branch drying pipes 55 set on each main drying pipe 52. In this application, the number of air supply modules 42 can be multiple, and each air supply module 42 operates independently. One drying component 5 corresponds to the drying of one agricultural material pile (baled material pile), such as Figure 5 As shown, if the distance between the other baled material piles is long when drying one of the baled material piles, this application can replace the connecting pipe 53 to achieve simultaneous drying of multiple baled material piles to meet the requirements of spatial angle and distance.
