Description

Technical Field

[0001] The utility model relates to the technical field of drying machine cooling, in particular to a drying machine with a cooling structure. Background Art

[0002] A dryer with a cooling mechanism is a high-end device that combines drying and cooling functions. Its design aims to provide users with a more comprehensive and efficient material handling solution. To achieve this goal, the dryer is equipped with cooling devices such as cooling fans and heat sinks. These cooling devices quickly activate after drying, effectively reducing the temperature of the dried material to a safe range, preventing overheating and potential deterioration or moisture reversion.

[0003] In current industrial production, materials often face high temperatures after drying. If not cooled promptly, the temperature drop during discharge can cause the material to regain moisture, which not only affects material quality but can also cause problems in subsequent production processes. Furthermore, during the drying process, some debris may adhere to the material. When the material is at a high temperature, this debris has weak adhesion and is easier to remove through cleaning. However, as the dryer's cooling mechanism begins to operate, the material temperature gradually decreases, and the adhesion between this debris and the material increases, making it difficult to completely remove it during cleaning.

[0004] Therefore, the dryer's cooling structure design is particularly important. A reasonable cooling structure should ensure a sufficiently large cooling area to improve cooling efficiency. This ensures that the material temperature drops quickly during the cooling process, preventing moisture resurgence. It also reduces the adhesion of debris after cooling, facilitating subsequent cleaning. Utility Model Content

[0005] The main purpose of the utility model is to provide a drying machine with a cooling structure, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A drying machine with a cooling structure comprises a frame, a drying box, a drying air blowing duct and a discharge port. The drying box is mounted on the frame by fasteners, and the drying air blowing duct is mounted on the drying box and blows air to dry the material in the drying box. The discharge port is located at the lower end of the drying box and discharges the material through the discharge port.

[0008] A screw conveying device is installed at the discharge port, and material transportation is achieved through the screw conveying device. The tail end of the screw conveying device is provided with an additional pipe, and the upper and lower ends of the additional pipe are respectively provided with a secondary pipe and an oblique discharge pipe. A filter partition is provided in the oblique discharge pipe, and the filter partition divides the discharge pipe into a corn kernel discharge channel and a debris discharge channel;

[0009] A cooling fan is installed at the upper end of the auxiliary pipe. The cooling fan blows cold air into the installation pipe and the discharge pipe to cool the corn kernels in the corn kernel discharge channel and blows the chips into the debris discharge channel for filtration.

[0010] As a preferred embodiment of the present invention, the side wall of the discharge pipe is provided with a plurality of protruding tubes, an insert plate is inserted into each of the protruding tubes, and a plurality of blocking brushes are provided on the inner end of the insert plate. The blocking brushes extend to the filter baffle, and the insertion plate is used to limit the amount of corn kernels passing through. The blocking brushes remove debris from the surface of the corn kernels and also limit the amount of corn kernels passing through.

[0011] As a preferred embodiment of the present invention, the insert plate and the blocking brush allow the corn kernels to slowly pass through the corn kernel discharge channel, and the cooling fan accelerates the discharge rate of the debris in the debris discharge channel;

[0012] As a preferred solution of the present invention, the installation pipe, discharge pipe and auxiliary pipe are designed as one piece, the inclination range of the discharge pipe is 15 degrees to 75 degrees, and the top of the filter baffle is designed in an arc shape and is adapted to the arc surface of the installation pipe;

[0013] As a preferred solution of the present invention, the filter partition is welded and fixed on the discharge pipe, and the filter holes opened on the filter partition are evenly distributed;

[0014] As a preferred solution of the present invention, the ports of the installation pipe, the discharge pipe and the auxiliary pipe are provided with connecting flanges, which are connected to the pipelines in contact with them via the connecting flanges.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this utility model, the dryer's cooling structure primarily consists of a cooling fan, an additional pipe, and a discharge pipe. The cooling fan, mounted at the upper end of the auxiliary pipe, is designed to blow cool air into the additional pipe and the discharge pipe. As the corn kernels pass through these two pipes, the cool air effectively cools them, preventing them from being damaged by high temperatures. This cooling structure not only ensures the quality of the dried corn kernels but also improves the safety of the entire drying process.

[0017] The debris separation and exhaust system is primarily implemented by an oblique discharge pipe, a filter baffle, and a cooling fan. A filter baffle is installed inside the discharge pipe, dividing it into a corn kernel discharge channel and a debris discharge channel. Wind force blows the debris into the debris discharge channel, while the corn kernels are discharged through the corn kernel discharge channel. This structure effectively separates the corn kernels from the debris, improving drying efficiency while also facilitating debris handling.

[0018] While cooling the corn kernels, the cooling fan also facilitates the movement of debris toward the debris discharge channel, accelerating the separation of the corn kernels and debris and improving the efficiency of the entire drying process. This timely cooling of the corn kernels by cold air prevents damage from high temperatures and ensures the quality of the dried corn kernels.

[0019] By controlling the cooling fan's air volume and speed, the speed at which corn kernels move through the discharge pipe can be adjusted, thereby enhancing discharge stability. Effective separation and removal of debris reduces debris accumulation in the work environment, improving the working environment for workers. The integrated design of the mounting pipe, discharge pipe, and auxiliary pipe, as well as the curved design of the filter baffle, enhance structural stability and extend the dryer's service life.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0027] like Figures 1 to 5 The figure shows a dryer with a cooling structure, which includes a frame 1, a drying box 2, a drying air duct 3, and a discharge port 4. The drying box 2 is securely mounted on the frame 1 using carefully designed fasteners, while the drying air duct 3 is cleverly installed on the drying box 2, providing continuous air drying to the material within the drying box 2. The discharge port 4 is located at the lower end of the drying box 2. This design ensures smooth discharge of the material after drying.

[0028] Specifically, the discharge port 4 is equipped with a screw conveyor 5, ensuring smooth and orderly material delivery. A mounting pipe 6 is cleverly designed at the tail end of the screw conveyor 5. The mounting pipe 6 has a secondary pipe 12 and an oblique discharge pipe 7 at its upper and lower ends, respectively. The oblique discharge pipe 7 is fitted with a filter baffle 9, which cleverly divides the discharge pipe 7 into two channels: a corn kernel discharge channel 10 and a debris discharge channel 11.

[0029] To further enhance the drying effect, a cooling fan 13 is installed at the upper end of the auxiliary pipe 12. This blows cool air into the loading pipe 6 and discharge pipe 7, effectively cooling the corn kernels in the corn kernel discharge passage 10 and also uses the wind to blow the debris into the debris discharge passage 11, thereby filtering and separating the material.

[0030] It's worth noting that the installation pipe 6, discharge pipe 7, and auxiliary pipe 12 utilize an integrated design, ensuring both structural stability and aesthetics. The inclination angle of the discharge pipe 7 is controlled between 15 and 75 degrees, ensuring smooth material discharge. The top of the filter baffle 9 features a curved design that perfectly matches the curved surface of the installation pipe 6, enhancing structural stability.

[0031] In addition, the filter holes opened on the filter partition 9 are designed with equidistant distribution, which ensures the uniformity of the filtering effect. In order to facilitate the connection with other pipelines, the ports of the installation pipe 6, the discharge pipe 7 and the auxiliary pipe 12 are all provided with connecting flanges 8. Example

[0032] This embodiment maintains the same overall structure as the first embodiment, but features further optimization and improvements in the discharge system. In addition to the original screw conveyor 5, additional pipe 6, auxiliary pipe 12, inclined discharge pipe 7, filter baffle 9, corn kernel discharge channel 10, and debris discharge channel 11, multiple protruding pipes 14 are added to the sidewall of the discharge pipe 7.

[0033] An insert plate 15 is inserted into each convex tube 14, and the inner end of the insert plate 15 is equipped with a plurality of blocking brushes 16. These blocking brushes 16 not only extend to the filter partition 9, but also can effectively limit the amount of corn kernels passing through and remove debris on the surface of the corn kernels.

[0034] The combined use of insert plate 15 and blocking brush 16 effectively controls the speed of corn kernels as they pass through corn kernel discharge passage 10, slowing them down. Simultaneously, the cooling fan 13 further enhances the discharge rate of debris from debris discharge passage 11, making the entire discharge process more efficient and stable.

[0035] Corn kernel drying process: The corn kernels to be dried are placed in the drying box 2. The drying box 2 is firmly mounted on the frame 1 by fasteners, providing a stable drying environment for the corn kernels.

[0036] The drying and blowing duct 3 is started to provide a continuous blowing and drying effect to the corn kernels in the drying box 2. This process will continue for a period of time until the corn kernels reach the desired dryness.

[0037] When the corn kernels are dried, the screw conveying device 5 starts to work and conveys the corn kernels to the loading pipe 6 in a stable and orderly manner.

[0038] During cooling: When the corn kernels pass through the loading pipe 6 and the discharge pipe 7, the cooling fan 13 starts working and blows cold air into the two pipes. This effectively cools the corn kernels and prevents them from being damaged by high temperatures.

[0039] The corn kernels and debris are separated by a filter partition 9 provided inside the discharge pipe 7. The corn kernels continue to be cooled in the corn kernel discharge channel 10, while the debris is blown into the debris discharge channel 11 by wind.

[0040] When the corn kernels pass through the discharge pipe 7, the corn kernels and debris are separated due to the presence of the filter partition 9. The debris is blown into the debris discharge channel 11 due to the action of gravity and wind.

[0041] The debris accumulates in the debris discharge passage 11 , and when a certain amount is reached, the debris can be discharged outside the machine by opening a related valve or interface.

[0042] The addition of a protruding tube 14 to the sidewall of discharge pipe 7 and the insertion of an insert plate 15 with a blocking brush 16 within the pipe further enhance the discharge system's functionality. The blocking brush 16 not only limits the amount of corn kernels passing through, slowing their speed as they pass through corn kernel discharge channel 10, but also effectively removes debris from the kernel surface, further improving the efficiency and stability of the discharge process.

[0043] The present invention is not limited to the above-described embodiments. Persons skilled in the art may make improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are considered to be within the scope of protection of the present invention. Any matters not described in detail in this specification are prior art known to those skilled in the art.
