Description

Technical Field

[0001] This invention relates to the field of wool processing equipment technology, specifically to a sorting device for wool processing and its usage method. Background Technology

[0002] Wool fabrics are widely used in the clothing industry due to their excellent warmth retention and wearing comfort. In the wool fabric production process, sorting is a crucial step in wool processing. Its main purpose is to meticulously classify the acquired wool of various qualities and types, ensuring that wool of the same type and quality is separated, while also removing impurities and stains. This step is essential for the efficiency of subsequent processing and the quality of the final wool products.

[0003] Existing sorting steps include breaking down, removing impurities, and quality grading. The breaking down and removing impurities is crucial, as it forms the basis for quality grading. This is because the collected wool contains a large number of particulate impurities and tends to clump together; without sufficient breaking down, grading is difficult. Current wool processing sorting devices perform breaking down and removing impurities separately, resulting in low processing efficiency. Furthermore, most use mechanical breaking down (e.g., stirring rods), which can easily damage the wool and reduce its quality. In addition, the particle size of impurities in wool varies greatly, and the wool itself is quite fine; therefore, conventional filtration methods are insufficient for efficiently separating wool from these particulate impurities. Summary of the Invention

[0004] The purpose of this invention is to provide a sorting device for wool processing and its usage method, which solves the defects of existing wool processing sorting devices, such as low efficiency in breaking down and removing impurities, easy damage to wool, and difficulty in efficiently separating particulate impurities.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A sorting device for wool processing, the device comprising:

[0007] A flow chamber, wherein the bottom of the flow chamber has an opening and the side wall of the flow chamber has a breathable plate;

[0008] A settling pipe is erected below the flow chamber, with its bottom end sealed and its top end connected to the opening of the flow chamber.

[0009] A wind-powered conveyor is connected to the side wall of the settling pipe, and the connection point is at a certain height from the bottom of the settling pipe.

[0010] The flow chamber is used to hold wool to be sorted, and the pneumatic conveyor is used to transport gas into the flow chamber through the settling pipe, so that the wool circulates and is gradually dispersed in the flow chamber, while particulate impurities in the wool fall to the bottom through the settling pipe under the action of gravity.

[0011] A further improvement is that the vent plate is inclined and located around the perimeter of the opening.

[0012] A further improvement is that the vent plate is flexibly connected to the side wall of the flow chamber, and a vibrating element is provided on the vent plate.

[0013] A further improvement is that the top of the settling pipe is rotatably connected to the opening of the flow chamber via a hinge, and a sealing gasket is provided at the connection.

[0014] A further improvement is that the bottom end of the settling pipe is provided with an openable and closable cap.

[0015] A further improvement is that the device also includes a heater for heating the gas as the pneumatic conveyor delivers the gas into the flow chamber.

[0016] A further improvement is that the device also includes a controller configured to: control the wind-powered conveyor to first operate in an air-dispersing mode, and then alternately operate in an air-dispersing mode and an exhaust mode. In the air-dispersing mode, the wind-powered conveyor is controlled to deliver gas into the flow chamber at a speed greater than a first threshold. In the air-dispersing mode, the wind-powered conveyor is controlled to deliver gas into the flow chamber at a speed that gradually decreases within a set range. In the exhaust mode, the wind-powered conveyor is controlled to extract gas from the flow chamber at a speed less than a second threshold.

[0017] A further improvement is that a vertically extendable connecting rod is provided at the top of the fluid chamber, a guide frame is provided at the bottom of the connecting rod, and a lifting pipe with two through ends is slidably provided on the outside of the guide frame. The lifting pipe is located directly above the opening, and a one-way valve plate is provided at the bottom of the lifting pipe.

[0018] In the air supply and dispersion mode and the air supply separation mode, the one-way valve is closed, and the lifting pipe slides upward along the guide frame to the highest point under the action of pneumatic force to overcome gravity; in the exhaust mode, the lifting pipe slides downward along the guide frame to the lowest point under the action of gravity, and the bottom end of the lifting pipe covers the through-hole, and the one-way valve opens under the action of negative pressure.

[0019] The present invention also provides a method of using the aforementioned wool processing sorting device, comprising the following steps:

[0020] S1. Load the wool to be sorted into the flow silo;

[0021] S2. Start the wind-powered conveyor to deliver gas into the flow chamber through the settling pipe, causing the wool to circulate and gradually break up in the flow chamber. Meanwhile, particulate impurities in the wool fall to the bottom through the settling pipe under the action of gravity.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) The device can simultaneously realize the breaking and impurity removal processes in the wool sorting process, and is easy to operate, which significantly improves the processing efficiency.

[0024] (2) The device uses wind power to automatically disperse and remove impurities, which can reduce damage to wool. It also uses a specific alternating control mode, which significantly improves the removal effect of impurities of different particle sizes compared to filter screen removal. It can also further dry the wool, thus helping to grade the wool quality in the future. Attached Figure Description

[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Combination Figure 1-3 As shown, a sorting device for wool processing includes:

[0031] The flow chamber 1 is narrow at the top and bottom and wide in the middle. The bottom center of the flow chamber 1 has an opening 2. The side wall of the flow chamber 1 is provided with a breathable plate 3. The breathable plate 3 is covered with air holes, and the air hole diameter is very small, so that wool and particle impurities are not easy to get out.

[0032] Settling pipe 4 is erected below the flow chamber 1. The bottom end of the settling pipe 4 is sealed, and the top end is connected to the opening 2 of the flow chamber 1.

[0033] The wind-powered conveyor 5, such as an air pump, is connected to the side wall of the settling pipe 4, and the connection point is at a certain height from the bottom of the settling pipe 4, generally not less than 20cm.

[0034] The flow chamber 1 is used to hold wool to be sorted, and the pneumatic conveyor 5 is used to transport gas into the flow chamber 1 through the settling pipe 4, so that the wool circulates and is gradually dispersed in the flow chamber 1, while the particulate impurities in the wool (mainly dust, sand, lanolin, etc.) fall to the bottom through the settling pipe 4 under the action of gravity.

[0035] The principle of this device is as follows: On the one hand, the wool is blown by the wind. Under the action of gravity and wind, the wool in the flow chamber 1 flows continuously towards and away from the opening 2, thus forming a circulating flow. During the flow, the clumps of wool will be broken up and dried. On the other hand, the wind speed is controlled by using the density and volume difference between the wool and particulate impurities. After the wool is broken up, it will continue to circulate, while the particulate impurities will automatically separate and settle. Finally, during the circulation process, they will gradually fall to the bottom of the settling pipe 4 and be collected. Furthermore, the wind-powered conveyor 5 is connected to the side wall of the settling pipe 4 to prevent particulate impurities from falling into the wind-powered conveyor 5 and affecting its operation. The connection point has a certain height to reduce the disturbance of the wind to the collected impurities.

[0036] Preferably, in this invention, the breathable plate 3 is inclined and located around the perimeter of the opening 2, which reduces the amount of wool remaining on the breathable plate 3. Furthermore, the breathable plate 3 is flexibly connected to the side wall of the flow chamber 1 (e.g., via an elastic membrane), and a vibrating element 6, such as a vibrating motor, is provided on the breathable plate 3. During operation, the vibrating element 6 drives the breathable plate 3 to vibrate, further preventing the wool from remaining on the breathable plate 3 and allowing it to quickly slide down to the opening 2 and continue participating in the circulation.

[0037] Preferably, in this invention, the top end of the settling tube 4 is rotatably connected to the opening 2 of the flow chamber 1 via a hinge, and a sealing gasket 7 is provided at the connection. This allows the entire flow chamber 1 to be rotated open, exposing its opening 2 upwards, which facilitates the loading and unloading of wool. When the flow chamber 1 is rotated to align with the top end of the settling tube 4, the sealing gasket 7 increases the sealing at the connection point.

[0038] Preferably, the bottom end of the settling pipe 4 is provided with an openable and closable cap 8, which is used to clean particulate impurities inside the settling pipe 4 after opening.

[0039] Preferably, the device further includes a heater 9 for heating the gas when the pneumatic conveyor 5 conveys the gas into the flow chamber 1, thereby promoting the drying of wool.

[0040] Preferably, in this invention, the device further includes a controller 10, which is configured to: control the pneumatic conveyor 5 to first operate in an air-dispersing mode, and then alternately operate in an air-separating mode and an exhaust mode. The air-dispersing mode involves controlling the pneumatic conveyor 5 to deliver gas into the flow chamber 1 at a speed greater than a first threshold. The air-separating mode involves controlling the pneumatic conveyor 5 to deliver gas into the flow chamber 1 at a speed that gradually decreases within a set range. The exhaust mode involves controlling the pneumatic conveyor 5 to extract gas from the flow chamber 1 at a speed less than a second threshold. The first threshold is greater than the second threshold, and both can be preset based on experience.

[0041] The purpose of the controller 10 is as follows: In actual operation, on the one hand, most of the wool is in a clump state and contains a certain amount of moisture, making it easy to settle; on the other hand, even if the permeable plate 3 is tilted and vibrated while continuously supplying gas into the flow chamber 1, a small amount of particulate impurities or wool may still remain at the permeable plate 3, affecting the circulation effect. Based on these two considerations, the present invention first controls the wind conveyor 5 to perform a certain duration of air supply and dispersing mode, for example, two minutes. In this mode, the wind speed is greater than the first threshold, the purpose of which is to prevent the clumps of wool from settling until they are fully dispersed; then, the air supply separation mode and the exhaust mode alternate; in the air supply separation mode, the speed of the supplied gas decreases gradually or in stages within a set range. The maximum value of the set range is based on the consideration of not damaging the wool and the power consumption of operation, and can generally refer to the aforementioned first threshold, while the minimum value requires that all wool does not settle. The control method of decreasing from large to small is mainly... The consideration is to address particulate impurities of different sizes or densities. At higher wind speeds, only large, high-density impurities settle, while at lower wind speeds, small, low-density impurities begin to settle, thus reducing concentration and entanglement during settling. Furthermore, wind speed variations facilitate the separation of impurities from the wool. In exhaust mode, reverse airflow allows particulate impurities or wool on the permeable plate 3 to detach. In this mode, the wind speed is below the second threshold to prevent wool from being drawn to the bottom of the settling pipe 4 in a short time (entering the settling pipe 4 has no impact, as long as it doesn't enter the pneumatic conveyor 5). Of course, during alternating operation, the air supply separation mode is primary, with the exhaust mode secondary. For example, every minute of air supply separation mode is followed by ten seconds of exhaust mode, alternating in this manner.

[0042] Preferably, in order to prevent wool from entering the settling tube 4 in a short time during the ventilation mode, a vertically extendable connecting rod 11 is provided at the top of the flow chamber 1. A guide frame 12 is provided at the bottom end of the connecting rod 11. A lifting pipe 13 with both ends passing through is slidably provided on the outside of the guide frame 12. The lifting pipe 13 is located directly above the opening 2, and a one-way valve plate 14 is provided at the bottom end of the lifting pipe 13.

[0043] In the air supply and dispersion mode and the air supply separation mode, the one-way valve 14 automatically closes, and the riser pipe 13 (made of some lightweight materials, such as polymer plastics) slides upward along the guide frame 12 to the highest point under the action of pneumatic force to overcome gravity. This will not affect the air intake at the opening 2, nor will it affect the airflow in the flow chamber 1. In the exhaust mode, the riser pipe 13 slides downward along the guide frame 12 to the lowest point under the action of gravity, and the bottom end of the riser pipe 13 covers the opening 2. The one-way valve 14 opens under the action of negative pressure. At this time, the riser pipe 13 raises the inlet height of the opening 2, and the wool in the chamber cannot slide directly into the settling pipe 4 in a short time, and it does not affect the air outlet at the opening 2.

[0044] The present invention also provides a method of using a sorting device for wool processing, the steps of which include:

[0045] S1. Load the wool to be sorted into the flow chamber 1;

[0046] S2. Start the wind-powered conveyor 5 to deliver gas into the flow chamber 1 through the settling pipe 4, so that the wool circulates and is gradually dispersed in the flow chamber 1, while the particulate impurities in the wool fall to the bottom through the settling pipe 4 under the action of gravity.

[0047] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
