Description

Technical Field

[0001] The present invention relates to the technical field of down processing, in particular to a steam processing device and method for removing odor from down. Background Art

[0002] During the production of down jackets, down raw materials often absorb various odors, such as grease and mold, due to various factors during storage, transportation and processing. Therefore, odor removal of down is an indispensable part of the down jacket production process.

[0003] Currently, the industry generally adopts steam treatment to remove odors from down. The down is placed in a relatively closed container, and then steam is introduced into the container to achieve the purpose of deodorization. The down is stacked together, which makes it difficult for the steam to fully and comprehensively contact the down. Although existing steam treatment devices are usually equipped with an agitator in the container, the agitator will stir the down during the steam treatment process in order to make the down fibers more dispersed and improve the uniformity of the contact between the steam and the down. However, the agitation of the agitator is usually based on a preset fixed pattern or a random pattern. Due to the filling and fluffiness of the down, the agitation is uneven. The down fibers in some areas are over-agitated, while the down in other areas may not be effectively agitated, forming a "steam blind spot". This agitation is relatively random, resulting in less than ideal steam deodorization effect.

[0004] Therefore, the present invention proposes a steam treatment device and method for removing down odor to solve the above problems. Summary of the Invention

[0005] The embodiments of the present invention aim to provide a steam treatment device and method for removing odor from down, so as to solve the above-mentioned problem.

An annular cavity is provided in the steam cylinder, a steam supply pipe is provided on the annular cavity, and steam outlet holes are evenly distributed on the inner wall of the annular cavity. The steam cylinder is also provided with a down scattering grid that can be shaken to disperse the down.

[0012] In an optional solution: a fleece return pipe is provided between the output end of the delivery pump and the material cavity, a first valve and a discharge port are provided on the fleece return pipe, and a second valve is provided on the discharge port.

[0013] A method for removing odor from down feathers, using the steam treatment device for removing odor from down feathers according to any one of the above technical solutions, comprises the following steps: S1: Put the down to be steam deodorized into the material cavity; S2: The down in the material cavity is continuously transported to the steam cylinder through the feeding mechanism. The down in the steam cylinder falls freely. Steam enters the annular cavity through the steam supply pipe and is then discharged through the steam outlet.

DETAILED DESCRIPTION

[0026] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] See also Figure 1 and Figure 2 A steam treatment device for removing odor from down includes a base shell 1, a support platform 14, and a steam cylinder 3 arranged on the support platform 14. The base shell 1 includes a material cavity 101 for placing down. The steam treatment device also includes a feeding mechanism 2 for conveying down into the steam cylinder 3. The down entering the steam cylinder 3 falls freely. An annular cavity 4 is provided in the steam cylinder 3, and a steam supply pipe 6 is provided on the annular cavity 4. Steam outlet holes 5 are evenly distributed on the inner wall of the annular cavity 4. The steam cylinder 3 is also provided with a movable down scattering grid 7 for dispersing the down. A delivery pump 9 is provided at the bottom of the steam cylinder 3 for conveying the fallen down back to the material cavity 101.

[0028] It should be noted that in this application, steam is supplied by an external device, such as a steam generator or other such device. The steam enters the annular cavity 4 through the steam supply pipe 6, and is then discharged through the steam outlet 5 to contact the down to achieve deodorization. In addition, the material cavity 101 is provided with a feeding port for feeding down.

[0029] The down to be steam-deodorized is put into the material chamber 101, and the down in the material chamber 101 is continuously transported to the steam cylinder 3 by the feeding mechanism 2. The down in the steam cylinder 3 falls freely, and the steam enters the annular chamber 4 through the steam supply pipe 6 and is then discharged through the steam outlet 5. The falling down is fully scattered by the down scattering grid 7, and the down is fully in contact with the steam during the falling process. The down that falls to the bottom of the steam cylinder 3 is transported back to the material chamber 101 by the delivery pump 9 to repeat the above action. This cycle lasts for a certain period of time, thereby achieving comprehensive and sufficient deodorization of the down and greatly improving the down steam deodorization effect.

[0030] Furthermore, a down return tube 10 is provided between the output end of the delivery pump 9 and the material chamber 101, and a first valve 15 and a discharge port 16 are provided on the down return tube 10, and a second valve 17 is provided on the discharge port 16. When deodorizing, the first valve 15 remains open and the second valve 17 remains closed. When deodorization is completed, the first valve 15 is closed and the second valve 17 is opened, so that the deodorized down is discharged through the discharge port 16.

[0031] See also Figure 1 、 Figure 3 and Figure 4 In one embodiment of the present invention, the base shell 1 further includes a material passage 102 connected to the material chamber 101 at one end, and the feeding mechanism 2 includes two rotating rollers 201 provided on the base shell 1, a conveyor belt 202 wound around the two rotating rollers 201, and a driving member for driving any of the rotating rollers 201 to rotate (not shown in the figure, the driving member is a servo motor, a reduction motor, etc. in the prior art, which is not limited or detailed here), and both sides of the conveyor belt 202 are connected to the material passage 102. The inner wall is in contact with each other, one of the rotating rollers 201 is arranged at one end of the feeding channel 102 away from the material chamber 101, and the other is arranged at the side of the material chamber 101 away from the feeding channel 102. Needles 203 are evenly distributed on the conveyor belt 202, and a slot 205 for the needles 203 to pass through is provided on the side of the rotating roller 201 away from the feeding channel 102. A drop hopper 204 is provided at the end of the feeding channel 102 away from the material chamber 101, and the steam cylinder 3 is located below the discharge port of the needles 203; The amount of down that can be accommodated by the material channel 102 is greater than the designed capacity of the material cavity 101 .

[0032] In this embodiment, the driving member drives any rotating roller 201 to rotate to drive the conveyor belt 201 to operate, and the needle body 203 arranged on the conveyor belt 202 pulls the down so that the down in the material chamber 101 gradually enters the material channel 102. The down in the material channel 102 falls under the action of gravity and is collected in the drop hopper 204. Then, it enters the steam cylinder 3 through the discharge port of the drop hopper 204 and falls freely. It should be explained that the purpose of the material channel 102 being able to accommodate down that is greater than the design capacity of the material chamber 101 is: before the down falls into the drop hopper 204, All the down put into the material chamber 101 is already located in the material channel 102, so that the down subsequently returned to the material chamber 101 will not accumulate in the material chamber 101, but will be transported into the material channel 102 to enter the steam cylinder 3 for the next time. There will be no insufficient deodorization of some down due to the stacking of down (due to the filling and fluffiness of down, the stacked down is transported at a greater random rate and is not transported in a completely top-to-bottom order, which will result in uneven transportation, causing some down to be transported into the steam cylinder 3 too many times, while some down is transported less times).

[0033] See also Figure 1 and Figure 5 In one embodiment of the present invention, a hollow part 12 is provided in the material feeding channel 102, and the hollow part 12 is located between the conveyor belts 202 and opposite to the drop hopper 204. Air outlet slots 21 are evenly distributed on the lower side of the hollow part 12, and a fan 13 for supplying air to the hollow part 12 is provided outside the material feeding channel 102, and through holes 18 are evenly distributed on the conveyor belt 202.

[0034] In this embodiment, air is supplied to the hollow member 12 by the fan 13, and then the air flow is discharged through the air outlet slot 21 and flows downward. The air flow passes through the through holes 18 on the conveyor belt 202 and acts downward on the down, preventing the down from adhering to the conveyor belt 202 and causing incomplete discharge (falling into the discharge hopper 204).

[0035] Furthermore, in this embodiment, a mesh plate 11 is provided on the drop hopper 204 for sealing the upper end of the steam cylinder 3. The lower side of the mesh plate 11 is in contact with the upper end surface of the steam cylinder 3. The mesh plate 11 blocks the upper end of the steam cylinder 3 to prevent down from escaping, and at the same time, meets the steam discharge demand.

[0036] See also Figure 1 、 Figures 6 to 8 In one embodiment of the present invention, the steam cylinder 3 is rotatably mounted on the support platform 14, the discharge port of the hopper 204 deviates from the center of the steam cylinder 3, a ring body 19 is sealed and rotatably mounted on the wall of the steam cylinder 3, and the steam supply pipe 6 is mounted on the ring body 19; The scattered pile grid 7 includes several grid plates 701 distributed from top to bottom, and the side edges of each grid plate 701 are in contact with the inner wall of the annular cavity 4. Several grid plates 701 are connected in series through at least one vertical rod 702, and the lower end of the vertical rod 702 passes through the bottom side of the steam cylinder 3. The support platform 14 is evenly provided with several concave inclined grooves 20 along the circumference of the rotation trajectory of the vertical rod 702.

[0037] It should be noted that, in this embodiment, the input end of the delivery pump 9 is coaxially and rotatably connected to the bottom of the steam cylinder 3 .

[0038] In this embodiment, the steam cylinder 3 is rotated to make the trajectory of the down landing point circularly distributed, and the landing point is continuously updated, so that the down is evenly distributed and falls in the steam cylinder 3. The rotation of the steam cylinder 3 drives the vertical rod 702 to revolve. Combined with the gravity of the grid plate 701 and the vertical rod 702, the lower end of the vertical rod 702 cyclically falls / moves out of the concave inclined groove 20, realizing the shaking of the scattered down grid 7, thereby shaking the down fallen on the grid plate 701, so that the down is evenly scattered downward and fully contacted with the steam.

[0039] Furthermore, in this embodiment, the steam treatment device also includes a driving mechanism 8 for realizing the rotation of the steam cylinder 3. The specific structure of the driving mechanism 8 adopts the existing technology, for example: it includes a ring gear provided on the steam cylinder 3 and a servo motor provided on the support platform 14, and the servo motor output shaft is provided with a gear meshing with the ring gear. As long as the steam cylinder 3 can be driven to rotate, this embodiment will not be limited or elaborated here.

[0040] The present invention also provides a method for removing odor from down, which uses the steam treatment device for removing odor from down described in any one of the above technical solutions, comprising the following steps: S1: Put the down to be steam deodorized into the material chamber 101; S2: The down in the material chamber 101 is continuously conveyed to the steam drum 3 by the feeding mechanism 2. The down in the steam drum 3 falls freely. Steam enters the annular chamber 4 through the steam supply pipe 6 and is then discharged through the steam outlet 5. The falling down is shaken by the down scattering grid 7 so that the down is fully scattered. During the falling process, the down comes into contact with the steam to be deodorized. S3: The down that has fallen to the bottom of the steam drum 3 is transported back to the material chamber 101 by the transport pump 9 and the action of step S2 is repeated. The cycle continues for a certain period of time to complete the removal of down odor.

[0041] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
