Description

Technical Field

[0001] This utility model relates to the field of spinning production technology, and more specifically to a filtration device for spinning chips. Background Technology

[0002] Spinning chips (such as polyester chips) are usually granular raw materials obtained through polymerization reactions. Before leaving the factory or entering the spinning process, these chips need to undergo drying, crystallization, and pre-crystallization to remove moisture, improve melting point uniformity, and prevent hydrolysis or degradation during the melting process. After drying, the chips need to be heated and melted in a melt extruder to form a melt, and then extruded into filaments through a spinneret in a spinning box. After cooling, stretching, winding, and other processes, they are finally made into polyester filaments or staple fibers.

[0003] To prevent the spinning chips from clogging the spinneret orifices and affecting fiber quality during melt spinning, the spinning chips need to be filtered to remove impurities such as dust and fine particles. Traditional chip filtration devices mostly adopt a vibrating screen structure, which only has a single rectangular filter screen and a small dust collection bin.

[0004] In actual operation, this structure suffers from problems such as limited filtration contact area, insufficient dust collection capacity, and low filtration efficiency, resulting in the inability to fully remove fine impurities from the chips, affecting the stability of the subsequent spinning process and product quality. In addition, the traditional vibrating screen has poor material feeding, which easily leads to a decrease in production efficiency. Utility Model Content

[0005] To address the technical problems existing in the filtration of spun yarn chips in the prior art, this utility model proposes a filtration device for spun yarn chips, comprising:

[0006] The slicing feed hopper is connected to a feed pipe at the bottom, and the feed pipe is equipped with a valve.

[0007] The filter chamber has a filter screen inside, and a first driving component is provided outside the filter chamber to drive the filter screen to rotate. The end of the feed pipe extends to the upper part of the filter chamber so that the spinning chips can enter the filter screen. The bottom of the filter chamber is provided with a discharge pipe.

[0008] The filter screen is constructed in a cylindrical shape, and the filter screen forms an inclined surface below the filter chamber. The spinning chips that enter the filter screen slide from the inclined surface toward the discharge pipe under the action of gravity, and finally fall into the discharge pipe at the material drop area at the bottom of the filter screen.

[0009] The continuous rotation of the filter screen causes the structure at different circumferential positions of the filter screen to form the inclined surface.

[0010] Preferably, the inclination angle of the inclined plane is 1 to 10 degrees.

[0011] Preferably, the filter screen is configured such that its diameter toward the end of the feed pipe is larger than its diameter toward the discharge pipe.

[0012] Preferably, the filter screen is configured such that the mesh diameter in the material dropping area is larger than the outer contour of the spinning chip, while the mesh diameter in other areas is smaller than the outer contour of the spinning chip, so that the spinning chip can fall into the discharge pipe through the mesh in the material dropping area.

[0013] Preferably, the filter chamber has an impurity discharge area located below the filter screen. Impurities that fall through the filter screen fall into the impurity discharge area. The filter chamber is equipped with a discharge component, which can be driven by a second driving component to push the impurities in the impurity discharge area into the collection chamber.

[0014] Preferably, the discharge component includes an auger.

[0015] Preferably, the impurity discharge area and the material drop area are both located below the inclined plane, and the length of the impurity discharge area and the material drop area is equal to the length of the inclined plane.

[0016] Preferably, the output shaft of the first drive component is provided with a bracket, which is connected to the inner wall of the filter screen.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] This invention combines a cylindrical rotating filter screen with an inclined feeding structure. During the filtration process of spinning chips, the rotating filter screen continuously tumbles the spinning chips, which can fully remove impurities and achieve more thorough separation. Impurities are automatically collected and discharged in the impurity discharge area, allowing for continuous operation and significantly improving the stability of spinning production and product quality.

Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, wherein:

[0020] Figure 1 This is a schematic diagram of the structure of a filtration device for spinning chips in the prior art;

[0021] Figure 2 This is a schematic diagram of the structure of the filtration device for the spinning chips shown in this utility model;

[0022] Figure 3This is a schematic diagram of the filter chamber shown in this utility model. Detailed Implementation

[0023] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, existing filtration devices typically use vibrating screens as screening elements, while rectangular filter screens and small-capacity dust collection bins are used. The filtration efficiency of rectangular filter screens is low and cannot meet filtration requirements.

[0025] Combination Figures 2 to 3 As shown, this utility model proposes a filtration device for spinning chips, including a chip feeding bin 10 and a filter bin 20. The bottom of the chip feeding bin 10 is connected to a feeding pipe 11, and a valve 12 is provided on the feeding pipe 11. The filter bin 20 is equipped with a filter screen 22 inside, and a first driving component 21 for driving the filter screen 22 to rotate is provided outside the filter bin 20.

[0026] The end 13 of the feed pipe 11 extends to the upper part of the filter chamber 20. The valve 12 on the feed pipe 11 can control whether the spinning chips in the filter chamber 20 can fall to the end of the feed pipe 11. When the valve 12 is opened, the spinning chips in the filter chamber 20 can enter the filter screen 22 along the feed pipe 11.

[0027] like Figure 2 and Figure 3 As shown, the filter screen 22 is constructed in a cylindrical shape. A bracket 212 is provided on the output shaft 211 of the first drive component 21, and the bracket 212 is connected to the inner wall of the filter screen 22.

[0028] Thus, when the output shaft 211 of the first drive component 21 rotates, the bracket 212 drives the cylindrical filter screen 22 to rotate around the axis of the output shaft 211. The axis of the output shaft 211 forms a certain angle with the horizontal direction. At this time, the upper edge of the continuously rotating filter screen 22 forms a fixed top surface, and the filter screen 22 forms an inclined surface 221 below the filter chamber 20.

[0029] The continuous rotation of the filter screen 22 causes the structure of the filter screen 22 at different circumferential positions to form an inclined surface 221.

[0030] Furthermore, within the filter chamber 20, an impurity discharge area 202 is provided below the filter screen 22. Impurities that fall through the filter screen 22 fall into the impurity discharge area 202. The filter chamber 20 is provided with a discharge component 24, which can be driven by the second drive component 25 to push the impurities in the impurity discharge area 202 into the collection chamber 26.

[0031] Optionally, the discharge component 24 includes an auger.

[0032] Thus, the spinning chips that enter the filter screen 22 slide from the inclined surface 221 toward the discharge pipe 23 under the action of gravity, and finally fall into the discharge pipe 23 at the bottom of the filter chamber 20 in the material drop area 201 at the bottom of the filter screen 22.

[0033] During this process, as the filter screen 22 rotates continuously, the spinning chips inside the filter screen 22 also continuously tumble along the inner wall of the filter screen 22. That is, under different vibration and tumbling conditions, the spinning chips move along the inclined plane 221 toward the discharge pipe 23. During this process, impurities on the surface of the spinning chips are shaken off and fall into the impurity discharge area 202, and are pushed forward by the discharge component 24 and moved into the collection bin 26.

[0034] In an optional embodiment, the inclination angle of the inclined plane 221 is 1 to 10 degrees.

[0035] Furthermore, the filter screen 22 is configured such that its diameter toward the end 13 of the feed pipe 11 is larger than its diameter toward the discharge pipe 23.

[0036] Thus, when the spinning chips move from the inclined plane 221 toward the discharge pipe 23, until they reach the area of ​​the discharge pipe 23, the spinning chips fall into the discharge pipe 23. The discharge pipe 23 is equipped with a second valve 231. After the second valve 231 is opened, the chips can fall to the outside for unified collection, resulting in clean spinning chips.

[0037] In the above embodiment, the filter screen 22 is configured such that the mesh diameter in the material drop area 201 is larger than the outer contour of the spinning chip, and the mesh diameter in other areas is smaller than the outer contour of the spinning chip, so that the spinning chip can fall into the discharge pipe 23 through the mesh in the material drop area 201.

[0038] Thus, when the spinning chips move inside the filter screen 22, they will not move to the outside of the filter screen 22 in areas other than the material drop area 201. Only impurities can fall out of the filter screen 22. When they move to the position of the material drop area 201, the mesh size increases, and the spinning chips can then fall out of the filter screen 22.

[0039] In an optional embodiment, the impurity discharge area 202 and the material drop area 201 are both located below the inclined surface 221, and the lengths of the impurity discharge area 202 and the material drop area 201 are equal to the length of the inclined surface 221.

[0040] Thus, as all the spinning chips that enter the filter screen 22 are constantly tumbling and moving within the filter screen 22, all the impurities in the impurity discharge area 202 are dislodged by vibration and fall into the impurity discharge area 202. The spinning chips cannot fall out in this area. When they move to the discharge area 201, the spinning chips can fall out and be discharged.

[0041] In conjunction with the above embodiments, this utility model combines a cylindrical rotating filter screen with an inclined feeding structure. During the filtration process of spinning chips, the rotating filter screen continuously tumbles the spinning chips, which can fully remove impurities and achieve more thorough separation. Impurities are automatically collected and discharged in the impurity discharge area, allowing for continuous operation and significantly improving the stability of spinning production and product quality.

[0042] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
