Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning equipment, and more specifically, to a device for cleaning coking in spinning box pipelines. Background Technology

[0002] The spinning box, also known as the spinning insulation box, is a major component of a screw extrusion spinning machine. It is a rectangular box with an outer insulation layer, and contains melt distribution pipes, metering pumps, and spinneret assemblies. The box is generally designed with multiple spinning sections. The heating methods of the box are generally internal heating and external heating, using biphenyl as the heat carrier.

[0003] With the improvement of people's living standards, the demand for textiles is becoming increasingly diversified and of higher quality, driving the textile industry to continuously develop towards high efficiency, precision, and intelligence. As an important raw material source for the textile industry, the spinning process of chemical fibers is crucial. The spinning box, as a key component of the spinning machine, directly affects the production quality and efficiency of chemical fibers. Melt spinning is one of the commonly used methods in chemical fiber production, with advantages such as high spinning speed and high production efficiency. In existing technologies, melt spinning often distributes molten polymers to various spinning positions through melt distribution pipes. However, due to the poor thermal stability of some polymers used in spinning, they are prone to thermal decomposition reactions under the high-temperature conditions of the spinning process, producing small molecule substances. These small molecule substances may further polymerize and condense to form coke-like substances, which adhere to the inner wall of the pipe, causing coking. Coking in the pipe will have adverse effects such as obstructed melt flow, uneven temperature distribution, inaccurate metering, and increased equipment load. Therefore, operators need to regularly clean the coking inside the pipe.

[0004] In existing technologies, the method for cleaning coking inside pipelines often involves operators using specialized scrapers, wire brushes, and other tools to scrape off the coking from the inner wall of the pipeline. Although this method has a basic cleaning effect, it is inefficient and ineffective. The residual coking will continue to affect the performance of the pipeline and shorten its service life. Furthermore, during manual cleaning, operators may cause scratches, abrasions, and other mechanical damage to the inner wall of the pipeline due to uneven force or improper operation. This damage will make the pipeline surface rough, increase the resistance to fluid flow, and may also become new coking attachment points, accelerating the reformation of coking. Therefore, this method needs to be improved. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a coking cleaning device for spinning box pipes, which has the advantage of automatically and efficiently cleaning the coking inside the pipes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for cleaning coking deposits in a spinning box pipe, comprising:

[0007] A screw, the right end of which is fixedly fitted with a fixing block;

[0008] A drive mechanism is provided at the left end of the screw;

[0009] A motion mechanism, wherein the motion mechanism is disposed inside the screw;

[0010] The motion mechanism includes a long shaft, the outer surface of which is movably connected to the inside of a screw and a fixed block, respectively. A motion block is fixedly installed at the right end of the long shaft, and a first hinge block is fixedly installed on the outer surface of the motion block. A motion rod is hinged inside the first hinge block, and a second hinge block is hinged at the other end of the motion rod. A scraper is fixedly installed on the outer surface of the second hinge block, and a rotating block is fixedly installed on the outer surface of the scraper. The outer surface of the rotating block is hinged to the inside of the long shaft.

[0011] As a preferred embodiment of this utility model, the driving mechanism includes:

[0012] A bracket, the right side of which is fixedly connected to the left end of the screw;

[0013] A cylinder, the outer surface of which is fixedly connected to the left side of the bracket, and the output end of which is fixedly connected to the left side of the long shaft.

[0014] As a preferred embodiment of this utility model, the outer surface of the screw is provided with an elongated groove, and a limit block is slidably connected inside the elongated groove.

[0015] As a preferred embodiment of this utility model, a fixing frame is fixedly connected to the outer surface of the limiting block, a sleeve block is fixedly installed on the outer surface of the fixing frame, a threaded sleeve is movably sleeved inside the sleeve block, and the inside of the threaded sleeve is threadedly sleeved with the outer surface of the screw.

[0016] As a preferred embodiment of this utility model, a motor is fixedly mounted on the outer surface of the fixing frame, a rotating shaft is fixedly sleeved at the other end of the motor output shaft, and a gear is fixedly sleeved on the outer surface of the rotating shaft.

[0017] As a preferred embodiment of this utility model, the outer surface of the gear is meshed with a toothed ring, and the inside of the toothed ring is fixedly sleeved with the outer surface of the threaded sleeve.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This is a coking cleaning device for a spinning box pipe. When the cylinder is running, it will drive the long shaft to move to the left. At this time, the long shaft will drive several first hinge blocks to the left through the moving block. At the same time, the several first hinge blocks will drive several second hinge blocks to move through several moving rods. At this time, the several second hinge blocks will drive several scrapers to rotate around the hinge point between several rotating blocks and fixed blocks as the axis. Then, the outer surface of several scrapers will contact the inner wall of the pipe during rotation. If the scrapers move to the left at this time, they can scrape off the coking on the inner wall of the pipe, thereby automatically and efficiently cleaning the coking inside the pipe.

[0020] 2. This coking cleaning device for spinning box pipes, due to the meshing of gear and gear ring, when the gear rotates, it will drive the threaded sleeve to rotate through the gear ring. Since the threaded sleeve is threadedly connected to the outer surface of the screw, and due to the limiting block limiting the screw, when the threaded sleeve rotates, it can drive the screw to move left and right. When the screw drives the fixed block to move to the right, the fixed block can extend into the pipe. When the screw drives the fixed block to move to the left, the scraper can scrape off the coking in the pipe. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] like Figures 1 to 4 As shown, this utility model provides a device for cleaning coking in the pipes of a spinning box, comprising:

[0028] Screw 1, with a fixing block 2 fixedly installed at the right end of screw 1;

[0029] The drive mechanism is located at the left end of screw 1;

[0030] The motion mechanism is located inside the screw 1;

[0031] The motion mechanism includes a long shaft 3, the outer surface of which is movably connected to the screw 1 and the fixed block 2 respectively. A motion block 4 is fixedly installed at the right end of the long shaft 3. A first hinge block 5 is fixedly installed on the outer surface of the motion block 4. A motion rod 6 is hinged inside the first hinge block 5. A second hinge block 7 is hinged at the other end of the motion rod 6. A scraper 8 is fixedly installed on the outer surface of the second hinge block 7. A rotating block 9 is fixedly installed on the outer surface of the scraper 8. The outer surface of the rotating block 9 is hinged to the inside of the long shaft 3.

[0032] When the long shaft 3 moves to the left along the inside of the screw 1 and the fixed block 2, the moving block 4 will move to the left under the drive of the long shaft 3. At this time, the moving block 4 will drive the moving rods 6 through several first hinge blocks 5. Then, the moving rods 6 will squeeze and push the scrapers 8 through several second hinge blocks 7, so that the scrapers 8 will rotate around the hinge point between the rotating blocks 9 and the fixed block 2. Subsequently, the scrapers 8 will contact the inner wall of the pipe during rotation. If the scrapers 8 move at this time, they can scrape off and clean the coking on the inner wall of the pipe.

[0033] The drive mechanism includes:

[0034] Bracket 10, the right side of bracket 10 is fixedly connected to the left end of screw 1;

[0035] Cylinder 11, the outer surface of cylinder 11 is fixedly connected to the left side of bracket 10, and the output end of cylinder 11 is fixedly connected to the left side of long shaft 3.

[0036] When cylinder 11 is running, it will be able to drive the long shaft 3 to move to the left.

[0037] The screw 1 has a long groove 12 on its outer surface, and a limit block 13 is slidably connected inside the long groove 12.

[0038] Since the limiting block 13 is internally slidably connected to the long groove 12, the limiting block 13 can limit the movement of the screw 1 through the long groove 12, so that the screw 1 can only move left and right.

[0039] Among them, the outer surface of the limiting block 13 is fixedly connected to the fixing frame 14, the outer surface of the fixing frame 14 is fixedly installed with the sleeve block 15, the inside of the sleeve block 15 is movably sleeved with the threaded sleeve 16, and the inside of the threaded sleeve 16 is threadedly sleeved with the outer surface of the screw 1.

[0040] Since the outer surface of the threaded sleeve 16 is in active engagement with the inside of the sleeve block 15, the threaded sleeve 16 can rotate around the engagement point with the sleeve block 15. Since the inside of the threaded sleeve 16 is threadedly engaged with the outer surface of the screw 1, the screw 1 can move left and right when the threaded sleeve 16 rotates.

[0041] Among them, a motor 17 is fixedly installed on the outer surface of the fixed frame 14, and a rotating shaft 18 is fixedly sleeved on the other end of the output shaft of the motor 17. A gear 19 is fixedly sleeved on the outer surface of the rotating shaft 18.

[0042] When motor 17 is running, shaft 18 will drive gear 19 to rotate.

[0043] Among them, the outer surface of the gear 19 is meshed with the toothed ring 20, and the inside of the toothed ring 20 is fixedly sleeved with the outer surface of the threaded sleeve 16.

[0044] Since gear 19 is meshed with gear ring 20, when gear 19 rotates, it will drive gear ring 20 to rotate. At this time, threaded sleeve 16 will rotate under the drive of gear ring 20.

[0045] Working principle and usage process of this utility model:

[0046] First, the operator places one end of the pipe inside the fitting block 15. Then, the operator starts the motor 17. At this time, the rotating shaft 18 drives the gear 19 to rotate. Since the outer surface of the gear 19 meshes with the outer surface of the gear ring 20, when the gear 19 rotates, it will drive the gear ring 20 to rotate. At this time, the threaded sleeve 16 will rotate around the fitting point with the fitting block 15 under the drive of the gear ring 20. Since the inside of the threaded sleeve 16 is threaded with the outer surface of the screw 1, when the threaded sleeve 16 rotates, it will drive the screw 1 to move as a whole. Since the outer surface of the limiting block 13 is slidably connected to the inside of the long groove 12, the limiting block 13 will limit the movement of the screw 1 as a whole through the long groove 12, so that it can only move left and right. At this time, the screw 1 will move to the right under the drive of the threaded sleeve 16. At the same time, the fixing block 2 will move to the right under the drive of the screw 1 and extend into the inside of the pipe, thus realizing the function of automatically extending into the inside of the pipe.

[0047] When the fixed block 2 moves to the target position to the right, the operator starts the cylinder 11. At this time, the right end of the cylinder 11 will drive the long shaft 3 to move to the left along the inside of the screw 1 and the fixed block 2. At this time, the moving block 4 will move to the left under the drive of the long shaft 3. At the same time, the moving block 4 will drive several first hinge blocks 5 to move to the left. At this time, several first hinge blocks 5 will drive several second hinge blocks 7 to move through several moving rods 6. At this time, several second hinge blocks 7 will squeeze and push several scrapers 8 respectively, so that several scrapers 8 will drive several rotating blocks 9 to rotate around the connection point with the fixed block 2 as the axis. Then, several scrapers 8 will contact the inner wall of the pipe during rotation. At this time, the operator closes the cylinder 11 and starts the motor 17. At this time, the threaded sleeve 16 will drive the screw 1 and the fixed block 2 to move to the left during rotation. During this process, several scrapers 8 will scrape off the coking inside the pipe during the leftward movement, thereby realizing the function of automatically and efficiently cleaning the coking inside the pipe.
