Description

Technical Field

[0001] This utility model belongs to the field of chemical fiber raw material filtration technology, specifically relating to a filtration device for processing chemical fiber raw materials. Background Technology

[0002] The full name of chemical fiber is chemical fiber, which refers to fibers made from natural or synthetic polymers. The preparation of chemical fibers typically involves first creating a spinning melt or solution from natural or synthetic polymers or inorganic substances, then filtering and metering it, extruding it through a spinneret into a liquid stream, and finally solidifying it into fiber. This initial fiber is called nascent fiber, and its mechanical properties are very poor. It must undergo a series of post-processing steps to meet the requirements of textile processing and use. Post-processing mainly involves stretching and heat setting to improve the fiber's mechanical properties and dimensional stability. Stretching orients the macromolecules or structural units in the nascent fiber along the fiber axis; heat setting primarily relaxes the internal stress within the fiber. Post-processing of wet-spun fibers also includes washing, oiling, and drying. When spinning filaments, the above processes allow for winding into a bobbin; when spinning staple fibers, additional processes such as crimping, cutting, and packaging are required. Traditionally, molten raw materials are added to the top of a filter screen during filtration, relying on the fluidity of the molten liquid for natural filtration. This method is slow, inefficient, and severely slows down production.

[0003] To address this, a rapid filtration device for chemical fiber raw materials used in chemical fiber production, with announcement number "CN214597622U", includes a tank. A feed pipe is located on one side of the tank, and a support plate is installed on the other side. A motor is mounted on the top of the support plate, and a rotating shaft is mounted on the output shaft of the motor via a coupling, extending into the tank. A first disc is connected to the feed pipe inside the tank, and the feed pipe passes through the first disc. A second disc is located at the end of the rotating shaft inside the tank. A filter screen is installed between the first and second discs. Two guide plates are located at the bottom of the tank's inner side, and a discharge pipe is connected between the two guide plates, extending downwards through the tank. A collection box is installed at the bottom of the tank. This rapid filtration device for chemical fiber raw materials used in chemical fiber production is simple to operate, utilizes centrifugal force to accelerate the flow rate of molten raw materials, increases filtration speed, saves time, improves production efficiency, and reduces operating costs.

[0004] However, although the aforementioned rapid filtration device for chemical fiber raw materials used in chemical fiber production can form an inner cylinder by fixing the filter screen with a first disc, a second disc, a filter screen, and a motor, and can rotate under the drive of the motor to achieve the effect of rapidly filtering molten chemical fiber raw materials by centrifugal filtration, the following obvious defects still exist in the use of the device: During the rotary filtration, some chemical fiber raw materials have a certain degree of adhesion and will stick to the inner wall of the filter screen cylinder, which will cause the filter screen pores to become clogged and prevent rapid filtration. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for processing chemical fiber raw materials, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for processing chemical fiber raw materials, comprising:

[0007] The housing has a chemical fiber filter drum that is rotatably mounted on a rotating shaft to perform rolling filtration of chemical fiber raw materials. A fixed feed pipe is provided on one side of the housing so that one end of the rotating shaft is located on the inner side. A feed guide block for guiding and outputting the chemical fiber raw materials after rapid filtration is provided on the vertical bottom side of the chemical fiber filter drum.

[0008] The air blowing pipe has air blowing heads evenly spaced at the bottom for cleaning raw materials, and one end of the air blowing pipe is connected to an air pump installed on one side of the box through a pipe. The bottom of the outer side of the box is provided with a feeding pump body for feeding material into one end of the chemical fiber filter roller. The outer side of the box is provided with a receiving rack for collecting the filtered chemical fiber raw materials and impurities.

[0009] Preferably, a servo motor is provided on the lower end face of the support plate at the bottom of the air pump. The rotating shaft of the servo motor is connected to one end of the rotating shaft rod through the transmission, and a reinforcing support rod is provided on the rotating shaft rod, so that the servo motor drives the chemical fiber filter roller to rotate and filter, and enhances the stability of the rotation filtration.

[0010] Preferably, the inner side of the chemical fiber filter drum is uniformly provided with crushing rods for rapid filtration of lumpy chemical fiber raw materials, and the inner side of the chemical fiber filter drum is fixed to one end of the reinforcing support rod. One end of the rotating shaft rod extends to the inner side of the fixed feed pipe and is rotatably mounted on the strip plate provided on the inner side of the fixed feed pipe through the bearing seat, so as to realize the function of crushing the lumpy raw materials in the rolling filter and speeding up the filtration speed.

[0011] Preferably, the inner ring of the discharge port of the chemical fiber filter roller is provided with a docking groove, and one end of the fixed feeding pipe extends to the inner side of the docking groove to movably dock with the chemical fiber filter roller for feeding, which is conducive to tilting the impurities generated by filtration to one side for output.

[0012] Preferably, a cleaning brush is provided between the air blow pipe heads at the bottom of the air blow pipe. The cleaning brush is attached to the upper outer surface of the chemical fiber filter drum, and the air blow pipe is inclinedly fixed to the upper inner side of the box body by a connecting rod, so that the chemical fiber filter drum can filter by using the cleaning brush during rotation.

[0013] Preferably, one end of the feeding pump body is connected to a feed pipe, and one end of the feed pipe passes through one side of the box body and extends to the inner side of one end of the chemical fiber filter roller. The upper and lower ends of the receiving rack are respectively provided with a receiving frame for collecting the filtered chemical fiber raw materials and an impurity receiving box for collecting the filtered impurities, so as to realize the separate collection of chemical fiber raw materials and impurities.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This filtration device for processing chemical fiber raw materials, through an air blowing pipe, an air blowing pipe head, and a cleaning brush and air pump installed on the air blowing pipe and attached to the upper end face of the chemical fiber filter drum, enables the chemical fiber filter drum to rapidly filter the chemical fiber raw materials while rotating and rolling. The air pump generates air and delivers it to the air blowing pipe. The air in the air blowing pipe is then blown onto the surface of the rotating chemical fiber filter drum through the evenly arranged air blowing pipe head, which can sweep away the chemical fiber raw materials adhering to the chemical fiber filter drum. At the same time, the cleaning brush cleans the filter holes on the chemical fiber filter drum, thereby achieving the sweeping of chemical fiber raw materials on the inner wall of the chemical fiber filter drum and the cleaning of the filter holes. This avoids the problem of adhesive chemical fiber raw materials adhering to the inner wall and clogging the filter holes, which would prevent rapid filtration, and further improves the efficiency of rapid filtration of chemical fiber raw materials.

[0015] The fiber filter drum, with its tilted rotation within the housing and evenly spaced crushing rods, works in conjunction with a fixed feed pipe. This allows the lumpy fiber material entering the filter drum to be broken down by the crushing rods on its inner wall. This facilitates better filtration of the fiber material by the filter drum, and the filtered impurities are discharged through the tilted feed pipe by the rotating drum. This eliminates the need for cleaning after the filter is stopped, reducing the risk of filter clogging and further improving the efficiency of rapid fiber filtration. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a filtration device for processing chemical fiber raw materials, comprising:

[0022] The housing 1 has a rotating shaft 2 that provides a chemical fiber filter roller 3 for filtering chemical fiber raw materials. The chemical fiber filter roller 3 is inclined inside the housing 1 to facilitate the filtration and output of impurities and enhance the filtration speed of the chemical fiber raw materials. A fixed feed pipe 4 is inclined on one side of the housing 1, with one end of the rotating shaft 2 located on the inside. This allows one end of the chemical fiber filter roller 3 to rotate on the outside of the fixed feed pipe 4, so that impurities are automatically tilted and poured out. A guide block 5 is provided on the vertical bottom side of the chemical fiber filter roller 3 to guide the rapidly filtered chemical fiber raw materials out. The surface of the guide block 5 is inclined outward from one end of the housing 1, so that the filtered chemical fiber raw materials are automatically output to one side for collection. At the same time, a discharge port is provided through one end of the housing 1.

[0023] The air blow pipe 6 has air blow pipe heads 7 evenly spaced at the bottom for cleaning the raw materials. The air blow pipe heads 7 are horizontally positioned at the end of the chemical fiber filter drum 3, which better cleans the chemical fiber raw materials on the inner wall. One end of the air blow pipe 6 is connected to an air pump 8 installed on one side of the box body 1 through a pipe, so that the air blow pipe heads 7 generate purging gas to clean the residue. The bottom of the outer side of the box body 1 is provided with a feeding pump body 9 for feeding material into one end of the chemical fiber filter drum 3. The input end of the feeding pump body 9 is connected to the discharge end of the external storage tank to transport the chemical fiber raw materials into the chemical fiber filter drum 3 for filtration. The outer side of the box body 1 is provided with a receiving rack 10 for collecting the filtered chemical fiber raw materials and impurities, so as to facilitate the collection of impurities and filtered chemical fiber raw materials.

[0024] A servo motor 11 is installed on the lower end of the support plate at the bottom of the air pump 8, which drives the rotating shaft 2 to rotate. The shaft of the servo motor 11 is connected to one end of the rotating shaft 2 through a transmission. The rotation of the rotating shaft 2 drives the chemical fiber filter roller 3 to rotate. A reinforcing support rod 12 is provided on the rotating shaft 2 to realize the rotation of the chemical fiber filter roller 3. The inner side of the chemical fiber filter roller 3 is evenly provided with crushing rods 13 for rapid filtration of lumpy chemical fiber raw materials, so that the lumpy chemical fiber raw materials being filtered by rolling are crushed. The inner side of the chemical fiber filter roller 3 is fixed to one end of the reinforcing support rod 12 to enhance the stability of the rotation of the chemical fiber filter roller 3. One end of the rotating shaft 2 extends to the inner side of the fixed feed pipe 4 and is rotatably mounted on a strip plate provided inside the fixed feed pipe 4 through a bearing seat, so that the rotating shaft 2 rotates inside the fixed feed pipe 4, while the fixed feed pipe 4 does not rotate with it.

[0025] A docking groove 14 is provided in the inner ring of the discharge port of the chemical fiber filter roller 3, which facilitates the output of impurities to the outside by placing one end of the fixed feeding pipe 4 inside one end of the chemical fiber filter roller 3. The other end of the fixed feeding pipe 4 extends into the docking groove 14 and movably docks with the chemical fiber filter roller 3 for feeding. A cleaning brush 15 is provided between the air blower heads 7 at the bottom of the air blower pipe 6, which can clean the filter holes of the rotating chemical fiber filter roller 3. The cleaning brush 15 is attached to the chemical fiber filter roller 3. The upper outer surface of the box is provided with an air blowing pipe 6, which is inclinedly fixed to the upper inner side of the box 1 by a connecting rod to achieve air blowing cleaning of the chemical fiber raw material. One end of the feeding pump body 9 is connected to the feeding pipe 16, and one end of the feeding pipe 16 passes through one side of the box 1 and extends to the inner side of one end of the chemical fiber filter roller 3. The upper and lower ends of the receiving rack 10 are respectively provided with a receiving frame 17 for collecting the filtered chemical fiber raw material and an impurity receiving box 18 for collecting the filtered impurities, so as to collect the impurities and the filtered chemical fiber raw material respectively.

[0026] Specifically, in use, the feeding pump body 9 is first connected to the external chemical fiber storage tank through a pipe. The feeding pump body 9 transports the chemical fiber raw material through the feed pipe 16 to one end of the chemical fiber filter drum 3. At this time, the servo motor 11 is started. The rotation of the servo motor 11 drives the rotating shaft 2 to rotate. The rotating shaft 2, with the evenly arranged reinforcing support rods 12, drives the chemical fiber filter drum 3 to rotate, causing the incoming chemical fiber raw material to roll circumferentially inside the chemical fiber filter drum 3. The moving chemical fiber raw material can be broken up by the crushing rod 13, which is conducive to the rolling filtration of the chemical fiber raw material. Due to the inclined rolling of the chemical fiber filter drum 3, the chemical fiber raw material can be tilted to one side for rapid filtration. The chemical fiber raw material falls downward through the filter holes onto the guide block 5 on the inclined surface and slides to one side to be collected in the collection frame 17. During filtration, the air pump 8 generates gas, which is delivered to the air blowing pipe 6. The gas in the air blowing pipe 6 is then output through the evenly arranged air blowing pipe heads 7 and blown onto the surface of the rotating chemical fiber filter roller 3. This blows away the chemical fiber raw materials adhering to the chemical fiber filter roller 3. At the same time, the cleaning brush 15 cleans the filter holes on the chemical fiber filter roller 3, thereby blowing away the chemical fiber raw materials on the inner wall of the chemical fiber filter roller 3 and cleaning the filter holes. This prevents the problem of adhesive chemical fiber raw materials adhering to the inner wall and clogging the filter holes, which would prevent rapid filtration. Finally, the filtered impurities are moved to one side by the tilted rotating chemical fiber filter roller 3 and discharged into the impurity collection box 18 through the tilted fixed discharge pipe 4. This eliminates the need to clean the impurities after the filtration device is stopped, and also reduces the problem of filter hole clogging during the chemical fiber filter rolling.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
