Description

Technical Field

[0001] The utility model belongs to the technical field of cotton textiles, in particular to a debris removal channel with a single air supply port. Background Art

[0002] In the cotton spinning industry, cotton collection is accompanied by some useless impurities, which restrict the quality of spinning. The function of the foreign fiber sorting machine (hereinafter referred to as the foreign fiber machine) is to detect and remove impurities in cotton. The foreign fiber machine adopts negative pressure operation, that is, the suction force generated by the fan is used to make the cotton flow through the foreign fiber machine to complete the detection and removal; the impurity removal channel also has a fan to generate suction to suck away the miscellaneous cotton and debris blown off by the spray valve from the impurity removal channel. This requires that the design of the impurity removal channel and its air supply port is very scientific to ensure the impurity removal effect and efficiency.

[0003] Currently, there is a snail impurity removal channel, the cross-section of which is similar to the side of a snail, and uses upper and lower double air inlets to intake air, and impurities are collected along the snail pipe. It has problems such as complex structure, high manufacturing cost, many welding defects, and uneven wind pressure (the wind pressure and suction are greater as it is close to the outlet of the fan, and the wind pressure and suction gradually decrease as it moves away from the fan), which affects the detection rate. For this reason, this application proposes a impurity removal channel with a single air inlet. Utility Model Content

[0004] In order to solve the problems raised in the above-mentioned background technology, the present invention provides the following technical solutions: a debris removal channel with a single air supply port, comprising a main channel and a debris removal channel, the debris removal channel is fixedly installed on the right side of the main channel, and the debris removal channel is connected to the main channel, a spray valve nozzle is fixedly installed on one side of the main channel, and an air supply port communicating with the main channel is fixedly installed at the bottom of the left end of the debris removal channel, the air supply port is arranged in a quarter arc shape, and the top opening of the air supply port is located at the bottom end of the connection between the main channel and the debris removal channel, the outer side wall of the top of the air supply port is provided with an air supply guide inclination angle, the inner side wall of the top of the air supply port is provided with an air supply guide fillet, a fixed plate is fixedly installed on the top of the bottom end of the air supply port, a flippable movable plate is provided at the bottom of the bottom end of the air supply port, and width adjustment screws are provided between both ends of the fixed plate and the movable plate.

[0005] Furthermore, the width adjustment screw includes a first bolt and a second bolt. The first bolt is threaded through the movable plate from bottom to top and abuts against the bottom of the fixed plate. The second bolt is threaded through the movable plate and the fixed plate in sequence from bottom to top.

[0006] Furthermore, the right end of the impurity removal channel is set as an impurity removal outlet, the left half of the bottom of the inner wall of the impurity removal channel is set as a convergent slope, and the angle of the convergent slope is between 8 and 10 degrees, and the right half of the bottom of the inner wall of the impurity removal channel is set as an outlet straight surface.

[0007] Furthermore, the area ratio of the main channel, the impurity removal channel and the air supply port is 3:2:1.

[0008] Furthermore, the air supply guide inclination angle is set to 20 degrees, and the radius value of the air supply guide fillet ranges from R20 to R50.

[0009] Furthermore, reinforcing ribs are fixedly installed on the bottom of the impurity removal channel, and a plurality of observation windows made of transparent material are fixedly installed on the side of the impurity removal channel.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The impurity removal channel has uniform suction, no vortex, and smooth airflow; the airflow entering from the air supply port is almost parallel to the airflow in the main channel. The spray valve only needs to spray the impurities a short distance (less than 50 mm) away from the main channel so that they can flow out smoothly from the impurity removal channel. They are detected and removed immediately with high efficiency; the airflow in the main channel will not enter the impurity removal channel, and there is no backflow phenomenon; only a very small amount (a little more than 8%) of the airflow entering from the air supply port enters the main channel, which has little effect on the efficiency of the main channel.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Depend on Figure 1-4 The utility model includes a main channel 1 and a debris removal channel 3. The debris removal channel 3 is fixedly installed on the right side of the main channel 1, and the debris removal channel 3 is connected to the main channel 1. A spray valve nozzle 2 is fixedly installed on one side of the main channel 1. A supplementary air port 5 communicating with the main channel 1 is fixedly installed at the bottom of the left end of the debris removal channel 3. The supplementary air port 5 is set to a quarter arc shape, and the top opening of the supplementary air port 5 is located at the bottom end of the connection between the main channel 1 and the debris removal channel 3. The outer side wall of the top of the supplementary air port 5 is provided with a supplementary air guide inclination 9, and the inner side wall of the top of the supplementary air port 5 is provided with a supplementary air guide fillet 10. A fixed plate 51 is fixedly installed on the top of the bottom end of the air supply port 5, and a reversible movable plate 52 is provided at the bottom of the bottom end of the air supply port 5. Width adjustment screws 6 are provided between both ends of the fixed plate 51 and the movable plate 52. The cotton flows from bottom to top along the main channel 1 under the action of the negative pressure suction of the upper end fan. The nozzle 2 of the spray valve blows impurities such as cotton and foreign matter into the impurity removal channel 3, and flows away under the action of the negative pressure suction of the fan at the end of the impurity removal outlet 4. The air flow rate of the impurity removal outlet 4 is completely provided by the air supply port 5, and the opening size of the air supply port 5 can be adjusted to achieve the purpose of adjusting the air intake.

[0020] If the air intake of the air supply port 5 is insufficient, the air flow of the main channel 1 will carry away some qualified cotton and flow out of the impurity removal outlet 4, seriously affecting the impurity removal quality; if the air intake of the air supply port 5 is too large, part of the air flow of the air supply port 5 will flow out of the main channel 1, affecting the suction force of the main channel 1 and further affecting the cotton conveying efficiency of the main channel 1. When the wind speed of the main channel 1 and the impurity removal channel 3 changes, the opening area of ​​the air supply port 5 can be adjusted by adjusting the width adjustment screw 6 of the air supply port 5 to ensure that the air flow from the air supply port 5 is always optimal, thereby solving the problem of air intake at the air supply port 5.

[0021] like Figure 3As shown, the width adjustment screw 6 includes a first bolt 61 and a second bolt 62. The first bolt 61 is threaded through the movable plate 52 from bottom to top and rests on the bottom of the fixed plate 51. The second bolt 62 is threaded through the movable plate 52 and the fixed plate 51 in sequence from bottom to top. Screwing the second bolt 62 and tightening the first bolt 61 can push open the movable plate 52 at the bottom of the air supply port 5, thereby increasing the air outlet of the air supply port 5; (the same structure on both sides, if necessary, a group can be added in the middle), to reduce the air outlet: loosening the first bolt 61 and tightening the second bolt 62 can pull in the movable plate 52 at the bottom of the air supply port 5, thereby reducing the air outlet of the air supply port 5.

[0022] like Figure 1 and Figure 2 As shown, the right end of the impurity removal channel 3 is set as a impurity removal outlet 4, the left half of the bottom of the inner wall of the impurity removal channel 3 is set as a convergent slope 11, and the angle of the convergent slope 11 is between 8 and 10 degrees, and the right half of the bottom of the inner wall of the impurity removal channel 3 is set as an outlet straight surface 12. After the air flow enters from the air supply port 5, it first passes through the air supply guide angle 9 to deviate from the impurity removal outlet 4, and then passes through the convergent slope 11 of the impurity removal channel 3 to reach the outlet straight surface 12. The angle of the convergent slope 11 is optimally between 8 and 10 degrees. At this time, the air flow can flow out from the impurity removal outlet 4 smoothly without generating vortices.

[0023] like Figure 1 and Figure 2 As shown, the area ratio of the main channel 1, the impurity removal channel 3 and the air supply port 5 is 3:2:1. At this time, only a small amount (a little more than 8%) of the flow of the air supply port 5 enters the main channel 1, and the air flow of the main channel 1 does not enter the impurity removal channel 3 at all.

[0024] like Figure 3 As shown, the air supply guide angle 9 is set to 20°, and the radius value range of the air supply guide fillet 10 is between R20-R50, so that the air flow can smoothly pass through the impurity removal channel 3 and flow out from the impurity removal outlet 4 after entering from the air supply port 5.

[0025] like Figure 1 and Figure 2 As shown, a reinforcing rib 7 is fixedly installed on the bottom of the impurity removal channel 3, and a plurality of observation windows 8 made of transparent material are fixedly installed on the side of the impurity removal channel 3. By setting the reinforcing rib 7, the stability of the bottom of the impurity removal channel 3 can be increased, and the observation window 8 can observe the situation inside the impurity removal channel 3.
