TECHNICAL FIELD

[0001] The application relates to the technical field of cashmere separation, and particularly relates to a down separator. BACKGROUND

[0002] Cashmere is obtained from the inner layer of a goat, and about 250 grams of the inner layer of a goat can be collected every year, and after the coarse hair and soil impurities are removed, the available cashmere raw material is not more than 100 grams; the cashmere fiber is soft and delicate, and has good warmth retention, and is therefore often used in high-grade clothing fabrics.

[0003] In the related art, when a combing worker combs the inner layer cashmere by using a special comb, the outer layer wool is also combed down, and since the cashmere and the wool have high curling degrees, the entanglement is very close and difficult to separate.

[0004] However, in the related art, the cashmere is separated by using a cashmere carding machine, and the separation is realized by using the weight and length difference between the cashmere and the wool through the carding between a cylinder and a flat plate. The extraction rate of the cashmere is low, the quality of the cashmere is damaged by repeated carding, the process flow is long, and the production efficiency is low. SUMMARY

The inner wall of the flow guide ring 3 is provided with 8-10 spiral flow guide blades 301, and the spiral angle is 35-45 degrees. When the feeding wool is less than 6 kg per hour, 8 flow guide blades are arranged, and the spiral angle is 45 degrees; when the feeding wool is 6-8 kg per hour, 9 flow guide blades are arranged, and the spiral angle is 40 degrees; when the feeding wool is greater than 8 kg per hour, 10 flow guide blades are arranged, and the spiral angle is 35 degrees.

[0041] As an embodiment, the first out of the warehouse 4 is connected with the flow guide ring 3 through the third connecting cone cylinder 9, the first out of the warehouse 4 is provided with a first out of the mouth 402 at the bottom of the position close to the second out of the warehouse 5, and is installed with a first hair blocking device 401; the second out of the warehouse 5 is connected with the first out of the warehouse 4 through the fourth connecting cone cylinder 10, the second out of the warehouse 5 is provided with a second out of the mouth 501 at the bottom of the position close to the out of the warehouse 6, and is installed with a second hair blocking device 502; the second out of the warehouse 5 is connected with the out of the warehouse 6.

A wool blocking ring 603 is installed on the top of the wool outlet bin 6, and a wool outlet 602 is arranged between the guide column 601 at the bottom of the wool outlet bin 6 and the wool blocking ring 603.

[0043] Figure 10 An example embodiment of the present application is shown in the schematic diagram of the flow field analysis when the set air draft speed is 30 m / s. Referring to Figure 10 As shown, the air flow is parallel to the inlet cylinder 1 and is immediately changed into a spiral flow after passing through the fixed fan blade 101, and then the entire separator is a spiral flow, and the spiral degree of the outer air flow is further increased after passing through the guide ring 3 to realize the discharge of the wool in the first wool outlet bin 4 and the second wool outlet bin 5.

[0044] As an embodiment, the working principle of the wool separator provided with two wool outlet bins and one impurity removal bin is as follows:

[0045] A suction device is arranged at the outlet of the fiber outlet bin 6. After the suction device is opened, raw wool is fed into the feeding cylinder 1, and the raw wool starts to move forward in a spiral after passing through the fan blade 101. The cashmere moves forward in a spiral with a short radius near the central axis under the centrifugal effect due to its light weight, while the wool moves forward in a spiral with a large radius on the inner wall due to its heavy weight under the centrifugal effect. After entering the impurity removal bin 2, the space increases, resulting in a decrease in air pressure. The center drops more than the periphery, causing the cashmere moving near the central axis to have a speed difference with the wool moving on the inner wall, and the separation is further increased. Impurities move forward in a spiral on the inner wall in the impurity removal bin 2 together with the wool due to their large weight. When the wool passes through the impurity falling hole 201 arranged at the bottom of the impurity removal bin 2 each time, the impulse generated by the collision between the wool and the impurity falling hole 201 will cause the impurities to be knocked out of the wool and fall into the impurity falling bin 203 on the impurity blocking plate 202. The impurity blocking plate 202 rotates periodically, causing the impurities to fall into the impurity falling bin 203. Subsequently, the cashmere and wool enter the flow guide ring 3. The cashmere located near the center will not contact the spiral flow guide piece 301 on the inner wall of the flow guide ring 3, but the wool moving on the inner wall will be subjected to an additional tangential force, increasing the degree of spiral movement of the wool, which is convenient for being discharged from the first wool outlet bin 4 and the second wool outlet bin 5. After entering the first wool outlet bin 4, the cashmere moves forward near the central axis, and the wool continuously spirals forward near the inner wall. The tangential rotational movement is blocked after moving to the first wool blocking device 401, and the transverse suction is blocked by the first wool blocking device 401. The wool falls from the first wool outlet 402 due to its weight. The working principle of the second wool outlet bin 5 is consistent with that of the first wool outlet bin 4, except that the radius of the outer wall cylinder is reduced. It is used to remove the wool that moves a small radius and does not enter the first wool blocking device 401 in the first wool outlet bin 4, but continues to move forward in a spiral after passing through the dome of the first wool blocking device 401. The cashmere enters the fiber outlet bin 6 and contacts the spiral flow guide column 601 on the inner wall of the fiber outlet bin 6. The cashmere moves forward along the spiral flow guide column 601 and is finally blocked by the fiber blocking ring 603 and falls from the fiber outlet 602 below the fiber outlet bin 6.

[0046] The working principle of the wool separator with only one wool outlet bin and no impurity removal bin is similar to that of the wool separator with two wool outlet bins and one impurity removal bin. A suction device is arranged at the outlet of the wool outlet bin. After the suction device is opened, raw wool is fed into the feeding cylinder. The raw wool starts to move forward in a spiral after passing through the fan blade. The cashmere moves forward in a spiral with a short radius near the central axis under the centrifugal force due to its light weight, while the wool moves forward in a spiral with a large radius on the inner wall due to its heavy weight under the centrifugal force. Subsequently, the cashmere and the wool enter the flow guide ring. The cashmere located near the center will not contact the spiral flow guide piece of the inner wall of the flow guide ring, and the wool that always moves on the inner wall will be added a new tangential force by the flow guide piece, so that the degree of spiral movement of the wool increases, facilitating the discharge of the wool outlet bin. After entering the wool outlet bin, the cashmere moves forward near the central axis, and the wool continuously spirals forward near the inner wall. The tangential rotation movement is blocked by the wool blocking device, and the transverse suction is blocked by the wool blocking device. The wool that continues to spiral forward after passing through the dome of the wool blocking device falls from the wool outlet due to its weight. The cashmere enters the wool outlet bin and contacts the spiral flow guide column of the inner wall of the wool outlet bin, moves forward along the spiral flow guide column, and is finally blocked by the cashmere blocking ring and falls from the wool outlet at the bottom of the wool outlet bin.

[0047] In summary:

[0048] By fixing the fan blade as a spinner, the raw wool will immediately perform a rotary motion after passing through the fan blade under strong wind suction. In a short stroke, the cashmere and the wool will be stratified due to the difference in centrifugal force, i.e. the cashmere will move forward in a spiral with a small radius near the central axis, and the wool will move forward in a spiral with a large radius near the inner wall. When entering the dust removal bin with a larger radius, the wind pressure will decrease due to the increase in space, and the speed difference between the movement of the cashmere at the center and the movement of the wool near the inner wall will increase, further improving the separation. When reaching the flow guide ring, the cashmere near the central axis will gradually change from spiral forward to smooth forward, while the wool near the inner wall will be added a new rotary force on the spiral flow guide piece. After entering the wool outlet bin, the wool near the inner wall is again thrown to the inner wall of the wool outlet bin to move in a spiral. After being blocked by the cashmere blocking device, it falls from the wool outlet. After passing through the first and second wool outlet bins, the cashmere enters the wool outlet bin and moves in a spiral on the flow guide column of the inner wall of the wool outlet bin, and is finally blocked by the cashmere blocking ring and falls from the wool outlet at the bottom of the wool outlet bin.

[0049] A impurity blocking plate is arranged in the impurity falling bin below the impurity falling hole. When the impurity blocking plate is periodically opened, the impurities fall into the impurity falling bin. When the impurity blocking plate is closed, a closed space is formed in the entire wool separator, so that the spiral airflow flows stably.

[0050] The above merely is the optional embodiment of the present application, and does not limit the present application, and any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application should be included in the protection scope of the present application.
