Description

Technical Field

[0001] The utility model relates to the field of down processing, in particular to an automatic dryer for down raw materials. Background Art

[0002] Down is a mixture of "feather" and "down", which needs to be cleaned during the processing and then dried after cleaning.

[0003] Currently, down is typically dried in a rotating drum with a filter screen installed on the surface. A hot air stream flows up and down inside the drum, drying the down. Down has fine hairs on its surface. During the drying process, these fine hairs can fall off and land in the filter screen, potentially clogging it and reducing airflow, thus affecting the drying process. To address this issue, we have designed an automatic dryer for down raw materials. Summary of the Invention

[0004] In order to solve the technical problem that a filter may be blocked, resulting in poor airflow and thus affecting the drying effect, the utility model provides an automatic dryer for down raw materials.

[0005] The utility model is implemented by the following technical solutions: an automatic dryer for down raw materials, comprising a bottom shell fixed above a bracket, an upper cover shell being screwed onto the bottom shell, two sets of support wheels being symmetrically and rotatably arranged on the left and right sides above the bottom shell, a drying drum being rotatably arranged above the four support wheels, the drying drum being rotatably placed between the upper cover shell and the bottom shell, a partition plate being sleeved on the left and right sides of the drying drum respectively, the partition plate being rotatably and sealed from the drying drum, the partition plate being sealedly connected to the bottom shell and the inner wall of the upper cover shell, and the partition plate, the bottom shell, and the inner wall of the upper cover shell forming a sealed heating chamber;

[0006] The upper housing is provided with a plurality of linearly distributed air intake rings mounted on the upper housing through a bracket. The air intake rings rotate and are sealed with the drying drum. The air intake rings are hollow inside to form an air intake cavity, which is communicated with the interior of the drying drum.

[0007] An air blowing assembly is installed on the outside of the upper cover shell, and the air blowing assembly is connected to a plurality of air intake rings.

[0008] As a further improvement to the above solution, a discharge port is provided below the right end of the bottom shell, and the left end of the discharge port is placed below the discharge end on the right side of the drying drum. The dried down falls directly onto the discharge port through the outlet at the right end of the drying drum and is discharged for easy collection.

[0009] A feed port is provided at the left end of the bottom shell, and the right end of the feed port extends into the interior of the drying drum without the two being in contact. Down can be directly added to the interior of the drying drum through the feed port, thereby facilitating drying.

[0010] As a further improvement of the above solution, shields are respectively provided at the left and right ends of the upper cover shell, and the bottom ends of the two shields are respectively close to the discharge port and the feed port, and there is a distance between them, so that the external openings on the left and right ends of the drying drum are reduced, thereby minimizing heat loss, and the down inside will not flow out through the openings on the left and right sides.

[0011] As a further improvement of the above scheme, the support wheel is rotatably mounted on the bottom shell through a bearing, and a drive motor is installed on the left end of the bottom shell through a motor bracket. The output shaft of the drive motor is connected to the support wheel on the rear side of the left end through a pulley and a belt. The rotation of the drive motor can rotate the support wheel, and then the drying drum can rotate accordingly, so as to facilitate drying the down inside it.

[0012] As a further improvement of the above solution, a plurality of spiral blades are provided at the left end of the drying drum, and the plurality of spiral blades are distributed in a circular array. The arrangement of the spiral blades enables the down entering the left end of the drying drum to be dispersed and then evenly enter the drying drum.

[0013] As a further improvement of the above solution, a plurality of evenly distributed distribution plates are provided inside the drying drum, and the distribution plates are L-shaped. When the distribution plates rotate, they can lift part of the down quilt, and then fall again so that the down can be dispersed, which is convenient for drying and improves the fluffiness.

[0014] As a further improvement of the above-mentioned solution, a plurality of groups of linearly distributed air jets are provided inside the drying drum, and the plurality of groups of air jets correspond one-to-one to a plurality of air intake rings respectively. Each group of air jets includes a plurality of annularly distributed air jets, and the air intake cavities of the air intake rings are connected. A fine mesh is also provided on the air jets for blocking the entry of down. The air intake cavity is an annular notch and passes through the air intake ring. The plurality of air jets in the same group are directly connected to the annular notch, so that the airflow in the air intake cavity can enter the interior of the drying drum, thereby blowing the down to make it float, thereby making it more fluffy.

[0015] As a further improvement of the above scheme, the blowing assembly includes a plurality of nozzles installed above the upper cover shell, and the plurality of nozzles are respectively connected to the air intake cavities of the plurality of air intake rings. The tail ends of the plurality of nozzles are connected to the connecting pipe, and the connecting pipe is connected to the air intake pipe. The air intake pipe is connected to an external air compressor. The high-pressure airflow can enter the plurality of nozzles through the air intake pipe and the connecting pipe, and then the air intake cavity and the air jet port can blow the down inside, causing it to roll up and down and become more fluffy.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The present invention configures the drying drum into a cylindrical structure with no gaps on its surface. Part of the drying drum is placed in a heating chamber formed by a bottom shell and an upper cover shell. A heating device is provided in the heating chamber. The down is partially lifted by the spiral blades and the distribution plate in the drying drum, and then falls back to disperse the down. This increases the heating area of the down and facilitates rapid drying of the down.

[0018] 2. By setting multiple groups of air jets in the drying drum and multiple air intake rings on the outside, combined with the provided blowing components, high-pressure airflow can enter the air intake cavity through the blowing components and the air jets to blow the down inside, making it roll up and down and more fluffy.

[0026] Please combine Figure 1-Figure 4 , an automatic dryer for down raw materials in this embodiment includes a bottom shell 1 fixed above the bracket, an upper cover shell 2 is screwed on the bottom shell 1, two sets of supporting wheels 5 are symmetrically and rotatably arranged on the left and right sides above the bottom shell 1, and a drying drum 7 is rotatably arranged above the four supporting wheels 5. The drying drum 7 is rotatably placed between the upper cover shell 2 and the bottom shell 1, and the left and right sides of the drying drum 7 are respectively sleeved with partition plates 13. The partition plates 13 and the drying drum 7 are designed to rotate and seal. The partition plates 13 are sealed with the bottom shell 1 and the inner walls of the upper cover shell 2. The partition plates 13 and the inner walls of the bottom shell 1 and the upper cover shell 2 form a closed heating chamber. A heating device is installed in the heating chamber. The heating device is any one of a variety of heating methods such as an electric heating plate or steam heating, a water bath heating, etc.;

[0027] The upper housing 2 is provided with a plurality of linearly distributed air intake rings 6 mounted thereon via a bracket. The air intake rings 6 rotate and are sealed against the drying drum 7. The air intake rings 6 are hollow inside to form an air intake cavity 61, which is in communication with the interior of the drying drum 7.

[0028] An air blowing assembly 3 is installed on the outside of the upper cover shell 2 , and the air blowing assembly 3 is connected to a plurality of air inlet rings 6 .

[0029] A discharge port 11 is provided below the right end of the bottom shell 1. The left end of the discharge port 11 is placed below the right discharge end of the drying drum 7. The dried down falls directly onto the discharge port 11 through the outlet at the right end of the drying drum 7 for easy collection.

[0030] A feed port 12 is provided at the left end of the bottom shell 1, and the right end of the feed port 12 extends into the interior of the drying drum 7 without the two contacting each other. Down can be directly added to the interior of the drying drum 7 through the feed port 12, thereby facilitating drying.

[0031] Shields are respectively provided at the left and right ends of the upper cover shell 2. The bottom ends of the two shields are respectively close to the discharge port 11 and the feed port 12, and there is a distance between them, so that the external diameters of the left and right ends of the drying drum 7 are reduced, thereby minimizing heat loss, and the down inside will not flow out through the openings on the left and right sides.

[0032] The support wheel 5 is rotatably mounted on the bottom shell 1 through a bearing. A drive motor 4 is installed on the left end of the bottom shell 1 through a motor bracket. The output shaft of the drive motor 4 is connected to the support wheel 5 on the rear side of the left end through a pulley and a belt. The rotation of the drive motor 4 can rotate the support wheel 5, and then the drying drum 7 can rotate accordingly, so as to dry the down inside it.

[0033] A plurality of spiral blades 71 are provided at the left end of the drying drum 7 , and the spiral blades 71 are distributed in a circumferential array. The arrangement of the spiral blades 71 allows the down entering the left end of the drying drum 7 to be dispersed and then evenly enter the drying drum 7 .

[0034] A plurality of evenly distributed distribution plates 72 are provided inside the drying drum 7, and the distribution plates 72 are L-shaped. When the distribution plates 72 rotate, they can lift part of the down quilt, and then fall again to disperse the down, which is convenient for drying and improves the fluffiness.

[0035] A plurality of groups of linearly distributed air jets 73 are provided inside the drying drum 7. The plurality of groups of air jets 73 correspond one-to-one to the plurality of air inlet rings 6. Each group of air jets 73 includes a plurality of annularly distributed air jets 73, and the air jets 73 are connected to the air inlet cavity 61 of the air inlet ring 6. A fine mesh is also provided on the air jets 73 for blocking the entry of down. The air inlet cavity 61 is an annular notch and passes through the air inlet ring 6. The plurality of air jets 73 in the same group are directly connected to the annular notch, so that the airflow in the air inlet cavity 61 can enter the interior of the drying drum 7, thereby blowing the down and making it float, thereby making it more fluffy.

[0036] The blowing assembly 3 includes a plurality of nozzles 32 installed above the upper cover shell 2. The plurality of nozzles 32 are respectively connected to the air inlet cavities 61 of the plurality of air inlet rings 6. The tail ends of the plurality of nozzles 32 are all connected to the connecting pipe 31, and the connecting pipe 31 is connected to the air inlet pipe 33. The air inlet pipe 33 is connected to an external air compressor. The high-pressure airflow can enter the plurality of nozzles 32 through the air inlet pipe 33 and the connecting pipe 31, and then the air inlet cavity 61 and the air jet 73 can blow the down inside, causing it to roll up and down and become more fluffy.

[0037] The working principle of an automatic dryer for down raw materials in the embodiment of the present application is as follows: in actual use, the left end of the device is higher than the right end, thereby facilitating the rightward movement of the down. The down is fed into the drying drum 7 through the feed port 12. Since the drying drum 7 is provided with a plurality of spiral blades 71 distributed in an annular pattern, the rotating drying drum 7 evenly disperses the down into the drying drum 7. Under the action of the plurality of distribution plates 72, the distribution plates 72 lift part of the down and then drop it again to disperse the down, thereby increasing the heating area of the down.

[0038] As the down moves to the right and dries, the high-pressure airflow generated by the external air compressor can enter the multiple nozzles 32 through the air inlet pipe 33 and the connecting pipe 31, and then the air inlet cavity 61 and the air jet 73 can blow the down inside, making it float and making it more fluffy. The down that moves to the rightmost end will flow out through the discharge port 11.

[0039] By setting the drying drum 7 into a cylindrical structure with no gaps on its surface, and partially placing it in the heating chamber formed by the bottom shell 1 and the upper cover shell 2, and providing a heating device in the heating chamber, the down will be partially lifted by the spiral blades 71 and the distribution plates 72 in the drying drum 7, and then fall down again to disperse the down, thereby increasing the heating area of the down and facilitating rapid drying of the down.

[0040] By arranging multiple groups of air jets 73 in the drying drum 7 and multiple air intake rings 6 on the outside thereof, and cooperating with the blowing assembly 3, high-pressure airflow can enter the air intake cavity 61 and the air jets 73 through the blowing assembly 3 to blow the down inside, causing it to roll up and down and become more fluffy.

[0041] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
