Abstract
Description
Technical Field
[0001] This invention relates to the field of nonwoven fabric spunbond spinning box technology, specifically to a medium guiding device, and more particularly to a fume extraction device for a spinning box. Background Technology
[0002] In the operation of the nonwoven spunbond spinning box, the uniformity of the oil fume extraction device is very important for the spinning stability of the spunbond production line. If the oil fumes are not removed in time after they are generated, they will adhere to the walls, equipment and other objects, which will seriously affect the uniformity of the extraction port of the oil fume extraction device in the spinning box.
[0003] The existing oil fume extraction device for spinning boxes uses the following scheme: pipes are arranged above the oil fume generation area, with inlets and outlets on the pipes. The outlet is connected to the impeller mechanism, and the negative pressure generated by the operation of the impeller mechanism causes the inlet to draw in the oil fume.
[0004] However, the temperature of the fumes is higher than that of the pipe. When the fumes inside the pipe come into contact with the cooler pipe wall, they will liquefy, thus affecting the suction.
[0005] Therefore, how to solve the technical problem of oil fumes easily liquefying on the outer and inner walls of pipes is a problem that urgently needs to be solved by those skilled in the art.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content
[0007] This disclosure provides at least one embodiment of a fume extraction device for a spinning box.
[0008] In a first aspect, embodiments of this disclosure provide a fume extraction device for a spinning box, comprising: a plurality of suction pipes connected end-to-end to form a suction ring; a plurality of partitions obliquely disposed within the respective suction pipes, dividing the suction pipes along their length into an inner chamber and an outer chamber; wherein the inner chamber is provided with a plurality of suction ports and a plurality of exhaust ports; the suction ports are disposed facing the inner ring of the suction ring; and the exhaust ports are disposed facing upwards from the suction ring.
[0009] In one optional embodiment, the upper sidewall of the suction pipe is provided with a plurality of guide tubes, each of the guide tubes being connected to a corresponding exhaust port; wherein the lower cross-section of the guide tube is larger than the upper cross-section of the guide tube.
[0010] In one alternative embodiment, the cross-section of the guide tube includes: elliptical, circular, rectangular, or square shapes.
[0011] In one alternative embodiment, the partition is tilted toward the outer ring of the suction ring.
[0012] In one alternative embodiment, the suction tube is a square tube; one side wall of the partition is connected to the inner wall below the suction tube, and the other side wall is connected to the inner wall of the suction tube in the direction of the outer ring of the suction ring.
[0013] In one alternative embodiment, the suction port is flat and distributed along the length of the suction tube.
[0014] In one alternative implementation, the inner chambers are connected end-to-end to form a suction channel.
[0015] Secondly, this disclosure also provides a fume extraction device for a spinning box, comprising: a plurality of suction pipes connected end-to-end to form a suction ring; wherein the suction pipes are provided with a plurality of suction ports and a plurality of exhaust ports; the suction ports are arranged facing the inner ring of the suction ring; the exhaust ports are arranged facing the upper part of the suction ring; a plurality of guide pipes are provided on the upper side wall of the suction pipes, and each guide pipe is respectively connected to a corresponding exhaust port; wherein the lower cross section of the guide pipe is larger than the upper cross section of the guide pipe.
[0016] In one optional embodiment, each of the suction tubes is provided with an obliquely arranged partition to divide the suction tube into an inner chamber and an outer chamber along its length; wherein the suction port and the exhaust port are both connected to the inner chamber.
[0017] In one alternative embodiment, the partition is tilted toward the outer ring of the suction ring.
[0018] The beneficial effect of this utility model is that the oil fume extraction device of this spinning box divides the area inside the extraction pipe into an inner chamber and an outer chamber by setting a baffle at an incline. This ensures that the oil fume only enters the inner chamber, which is closer to the center of the extraction ring. The temperature of the pipe wall that makes up the inner chamber is higher than that of the pipe wall that makes up the outer chamber. This makes it less likely for the oil fume to liquefy upon cooling after entering the inner chamber, thus affecting the uniformity of the airflow at the extraction port.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0030] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.
[0031] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0032] like Figure 1 As shown, at least one embodiment provides a fume extraction device for a spinning box, including: a plurality of horizontally arranged suction pipes 1, each suction pipe 1 being connected end to end to form a suction ring 10.
[0033] In this embodiment, the suction ring 10 is disposed above the area where oil fumes are generated. Optionally, the suction ring 10 is connected to an impeller mechanism, and the suction ring 10 is generated by the impeller mechanism to absorb oil fumes.
[0034] like Figure 2 As shown, in some embodiments, each suction tube 1 is provided with a partition 2, which is arranged along the length of the suction tube 1 to divide the area inside the suction tube 1 into an inner chamber 11 and an outer chamber 12.
[0035] Specifically, the inner chamber 11 has several suction ports 13 and several exhaust ports 14; the suction ports 13 are arranged facing the inner ring of the suction ring 10; the exhaust ports 14 are arranged facing the top of the suction ring 10.
[0036] In this embodiment, the baffle 2 is inclined to guide the fumes into the exhaust port 14. At the same time, due to the presence of the baffle 2, the fumes will only enter the inner chamber 11. The inner chamber 11 is closer to the center area of the suction ring 10. That is, the temperature of the pipe wall constituting the inner chamber 11 will be higher than the temperature of the pipe wall constituting the outer chamber 12. This makes it difficult for the fumes to liquefy when they enter the inner chamber 11.
[0037] like Figure 3 As shown, in some embodiments, the upper sidewall of the suction pipe 1 is provided with a plurality of guide pipes 3, each guide pipe 3 being connected to a corresponding exhaust port 14; wherein the lower cross section of the guide pipe 3 is larger than the upper cross section of the guide pipe 3.
[0038] In this embodiment, since the lower cross section of the guide pipe 3 is larger than the upper cross section, the oil fumes in the suction pipe 1 can be more easily extracted, that is, the oil fumes are less likely to accumulate in the suction pipe 1 and affect the uniformity of the wind speed.
[0039] In some embodiments, the cross-section of the guide tube 3 includes: elliptical, circular, rectangular, or square.
[0040] In this embodiment, when there is no oil fume accumulation in the suction pipe 1, a uniform wind speed can be generated at the suction port 13, thereby ensuring that the equipment that generates oil fumes can be used more stably.
[0041] In some embodiments, the partition 2 is inclined toward the outer ring of the suction ring 10.
[0042] In this embodiment, when the included angle α is too small, the partition 2 cannot play a guiding role; when the included angle α is too large, it will cause the space of the inner cavity 11 to be too small, thereby affecting the flow of oil fumes.
[0043] In some embodiments, the suction tube 1 is a square tube; one side wall of the partition 2 is connected to the inner wall below the suction tube 1, and the other side wall is connected to the inner wall of the suction tube 1 in the direction of the outer ring of the suction ring 10.
[0044] In some embodiments, the suction port 13 is flat, and each suction port 13 is distributed along the length direction of the suction tube 1; wherein, the flat suction port 13 is more likely to suck up oil fumes.
[0045] In some embodiments, the internal chambers 11 are connected end to end to form a suction channel.
[0046] like Figures 1 to 3 As shown, at least one embodiment also provides a fume extraction device for a spinning box, comprising: a plurality of suction pipes 1, each suction pipe 1 being connected end to end to form a suction ring 10; wherein the suction pipe 1 has a plurality of suction ports 13 and a plurality of exhaust ports 14; the suction ports 13 are arranged facing the inner ring of the suction ring 10; the exhaust ports 14 are arranged facing the upper part of the suction ring 10; a plurality of guide pipes 3 are provided on the upper side wall of the suction pipe 1, each guide pipe 3 being connected to a corresponding exhaust port 14; wherein the lower cross section of the guide pipe 3 is larger than the upper cross section of the guide pipe 3.
[0047] In this embodiment, since the lower cross section of the guide pipe 3 is larger than the upper cross section, the oil fumes in the suction pipe 1 can be more easily extracted, that is, the oil fumes are less likely to accumulate in the suction pipe 1 and affect the uniformity of the wind speed.
[0048] In some embodiments, each suction tube 1 is provided with an obliquely arranged partition 2 to divide the suction tube 1 into an inner chamber 11 and an outer chamber 12 along its length; wherein the suction port 13 and the smoke exhaust port 14 are both connected to the inner chamber 11.
[0049] In summary, this spinning box fume extraction device divides the area inside the extraction pipe 1 into an inner chamber 11 and an outer chamber 12 by setting a partition 2 at an incline on the extraction pipe 1. This ensures that the fumes only enter the inner chamber 11, which is closer to the center of the extraction ring 10. As a result, the temperature of the pipe wall in the inner chamber 11 is higher than that in the outer chamber 12. This makes it less likely for the fumes to liquefy upon cooling after entering the inner chamber 11, thus preventing them from affecting the uniformity of the extraction port.
