Description

Technical Field

[0001] The present invention relates to the technical field of wool processing equipment, and in particular to a sorting device for wool processing and a use method thereof. Background Art

[0002] Wool fabrics have excellent warmth retention and are comfortable to wear, and are widely used in the clothing field. In the wool fabric production process, the sorting process is an important part of the wool processing process. Its main purpose is to carefully classify the various qualities and types of wool purchased, ensure that wool of the same type and quality is separated, and remove impurities and stains. This step is crucial to the efficiency of the subsequent processing and the quality of the final wool products.

[0003] The existing sorting steps include breaking up, removing impurities and quality grading. Among them, the breaking up and removing impurities process is very important, which is the basis of quality grading, because the collected wool contains a large amount of particulate impurities and is easy to clump. If it is not fully broken up, it is difficult to grade. The existing wool processing sorting devices are separated when breaking up and removing impurities, which has low processing efficiency, and most of them use mechanical breaking (such as stirring rods), which is easy to damage the wool and reduce the quality. In addition, the particle size of the particulate impurities in the wool varies, and the wool is relatively fine. Therefore, it is difficult to efficiently separate the wool from the particulate impurities through conventional filter separation measures. Summary of the invention

[0004] The object of the present invention is to provide a sorting device for wool processing and a method for using the same, which solves the defects of the existing sorting device for wool processing, such as low efficiency in breaking up and removing impurities, easy damage to wool, and difficulty in efficiently separating particulate impurities.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0009] A wind conveying member, wherein the wind conveying member is connected to the side wall of the settling pipe, and the connection point is at a certain height from the bottom end of the settling pipe;

[0010] The flow bin is used to accommodate wool to be sorted, and the wind conveyor is used to convey gas into the flow bin through a sedimentation pipe, so that the wool circulates in the flow bin and is gradually broken up, while the granular impurities in the wool fall to the bottom through the sedimentation pipe under the action of gravity.

[0015] A further improvement is that the device also includes a heater for heating the gas when the wind conveying member conveys the gas into the flow chamber.

[0016] A further improvement is that the device also includes a controller, which is configured to: control the wind transport component to first work in an air supply dispersion mode, and then work alternately in an air supply separation mode and an exhaust mode, wherein the air supply dispersion mode is to control the wind transport component to transport gas into the flow bin, and the speed of transporting gas is greater than a first threshold value, the air supply separation mode is to control the wind transport component to transport gas into the flow bin, and the speed of transporting gas changes from large to small within a set range in a staged or gradual manner, and the exhaust mode is to control the wind transport component to extract gas from the flow bin, and the speed of extracting gas is less than a second threshold value.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here 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. Technical personnel in this field 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, the device comprises:

[0031] The flow bin 1 has an overall size of being narrow at the top and bottom and wide in the middle. A through hole 2 is provided at the center of the bottom of the flow bin 1. A vent plate 3 is provided on the side wall of the flow bin 1. The vent plate 3 is densely covered with pores, and the pore diameter is very small, so that wool and granular impurities are not easy to drill out.

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

[0033] A wind conveying member 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 at a height of not less than 20 cm;

[0034] Among them, the flow bin 1 is used to accommodate the wool to be sorted, and the wind conveyor 5 is used to transport gas into the flow bin 1 through the sedimentation pipe 4, so that the wool circulates in the flow bin 1 and is gradually broken up, and the particulate impurities in the wool (mainly dust, sand, lanolin, etc.) fall to the bottom through the sedimentation pipe 4 under the action of gravity.

[0035] The principle of the device is as follows: on the one hand, the wool is blown by wind, and the wool in the flow bin 1 continuously flows toward and away from the opening 2 under the action of gravity and wind, thereby forming a circulating flow, and the wool that clumps during the flow will be broken up and dried; on the other hand, the density and volume differences between the wool and particulate impurities are used to control the wind speed, so that after the wool is broken up, the wool will continue to circulate, and the particulate impurities will automatically separate and settle, and finally gradually fall to the bottom of the sedimentation pipe 4 and be collected during the circulating flow. In addition, the wind conveying member 5 is connected to the side wall of the sedimentation pipe 4 to prevent the particulate impurities from falling into the wind conveying member 5 and affecting its operation. The connection point has a certain height to reduce the disturbance of the collected impurities by the wind.

[0036] In the present invention, preferably, the air permeable plate 3 is tilted and located around the opening 2, so that the wool can be reduced from staying at the air permeable plate 3. In addition, the air permeable plate 3 is flexibly connected to the side wall of the flow bin 1 (for example, connected by an elastic membrane), and a vibrating member 6, such as a vibration motor, is provided on the air permeable plate 3. During operation, the air permeable plate 3 is driven to vibrate by the vibrating member 6, which can further prevent the wool from staying at the air permeable plate 3, allowing it to quickly slide to the opening 2 and continue to participate in the circulation flow.

[0037] Preferably in the present invention, the top end of the sedimentation tube 4 is rotatably connected to the opening 2 of the flow bin 1 by a hinge, and a sealing gasket 7 is provided at the connection, so that the entire flow bin 1 can be rotated open to expose its opening 2 upward, which is convenient for loading and removing wool, and when the flow bin 1 is rotated to be aligned with the top end of the sedimentation tube 4, the provision of the sealing gasket 7 can increase the sealing of the joint.

[0038] Preferably in the present invention, an openable and closable cover 8 is provided at the bottom end of the sedimentation tube 4 for cleaning the particulate impurities in the sedimentation tube 4 after opening.

[0039] Preferably in the present invention, the device also includes a heater 9 for heating the gas when the wind conveying member 5 conveys the gas into the flow bin 1, so as to promote the drying of the wool.

[0040] Preferably, the device of the present invention further comprises a controller 10, and the controller 10 is configured to: control the wind conveyor 5 to work in the air supply and dispersion mode first, and then work alternately in the air supply and separation mode and the exhaust mode, wherein the air supply and dispersion mode is to control the wind conveyor 5 to convey gas into the flow bin 1, and the speed of conveying gas is greater than the first threshold value, the air supply and separation mode is to control the wind conveyor 5 to convey gas into the flow bin 1, and the speed of conveying gas changes from large to small in a set range in a staged or gradual manner, and the exhaust mode is to control the wind conveyor 5 to extract gas from the flow bin 1, and the speed of extracting gas is less than the second threshold value. The first threshold value is greater than the second threshold value, and both can be preset based on experience.

[0041] The purpose of setting up the controller 10 is: in the actual operation process, on the one hand, the wool is mostly in a clumping state in the early stage, and contains a certain amount of moisture, and is easy to settle; on the other hand, the gas is continuously transported into the flow bin 1. Even if the breathable plate 3 is tilted and vibrated, there may still be a small amount of particulate impurities or wool remaining on the breathable plate 3, affecting the circulation effect. Based on these two aspects, the present invention first controls the wind conveying member 5 to perform an air supply and dispersion mode for a certain period of time, such as two minutes. In this mode, the wind speed is greater than the first threshold value, in order to avoid the sedimentation of clumped wool until it is fully dispersed; then, the air supply separation mode and the exhaust mode are operated alternately; in the air supply separation mode, the speed of the conveying gas changes from large to small in a staged or gradual manner within the set range. The maximum value of the set range takes into account factors such as not damaging the wool and operating power consumption, and can generally refer to the above-mentioned first threshold value, while the minimum value requires that all wool does not settle. The control method from large to small is mainly What needs to be considered is that for granular impurities of different particle sizes or densities, only large particles and high-density impurities can settle when the wind speed is high, while small particles and low-density impurities begin to settle when the wind speed is low, thereby reducing the phenomenon of concentrated and mixed sedimentation, and the change in wind speed is also conducive to the full separation of impurities and wool; in the exhaust mode, wind backblowing can be achieved to allow the granular impurities or wool on the breathable plate 3 to separate. In this mode, the wind speed is less than the second threshold, the purpose is to prevent the wool from being drawn to the sedimentation tube 4 near the bottom position in a short time (entering the sedimentation tube 4 has no effect, as long as it does not enter the wind conveying member 5). Of course, during alternating operation, the air supply separation mode is the main one, and the exhaust mode is the auxiliary one. For example, for every one minute of air supply separation mode, the exhaust mode will be performed for ten seconds, and so on.

[0042] Preferably in the present invention, in order to prevent the wool from entering the sedimentation tube 4 in a short time in the exhaust mode, a vertically retractable connecting rod 11 is provided at the inner top of the flow bin 1, and a guide frame 12 is provided at the bottom end of the connecting rod 11. A lifting pipe 13 with two ends passing through is slidably provided on the outside of the guide frame 12. The lifting pipe 13 is located directly above the through port 2, and a one-way valve sheet 14 is provided at the bottom end of the lifting pipe 13.

[0043] In this way, in the air supply dispersion mode and the air supply separation mode, the one-way valve plate 14 is automatically closed, and the lifting pipe 13 (made of some lightweight materials, such as polymer plastics, etc.) overcomes gravity under the action of pneumatic force and slides upward to the highest point along the guide frame 12, which will not affect the air intake at the port 2, nor will it affect the wind flow in the flow bin 1; in the exhaust mode, the lifting pipe 13 slides downward to the lowest point along the guide frame 12 under the action of gravity, and the bottom end of the lifting pipe 13 covers the port 2, and the one-way valve plate 14 opens under the action of negative pressure. At this time, the lifting pipe 13 raises the entrance height of the port 2, and the wool in the bin cannot directly slide down or flow into the sedimentation pipe 4 in a short time, and it does not affect the air outlet at the port 2.

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

[0045] S1, loading the wool to be sorted into the flow bin 1;

[0046] S2, start the wind conveying member 5, and convey gas into the flow bin 1 through the settling pipe 4, so that the wool circulates in the flow bin 1 and is gradually broken up, and the granular impurities in the wool fall to the bottom through the settling pipe 4 under the action of gravity.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
