Description

Technical Field

[0001] This utility model relates to the field of spinning oil production, specifically a defoaming treatment mechanism for FDY spinning oil by extrusion filtration. Background Technology

[0002] Spinning oil production refers to the process of compounding, emulsifying and other processes to produce lubricants, antistatic agents and other components into auxiliaries for chemical fiber spinning, in order to improve the spinnability and quality of fibers. FDY (fully drawn yarn) spinning oil is prone to mixing with air bubbles and impurities during the chemical fiber production process, which affects fiber quality. The extrusion filtration defoaming treatment mechanism is a device specifically designed to remove air bubbles and particulate impurities from the oil. Its core principle is to achieve efficient purification through physical methods.

[0003] In existing technologies, when treating spinning oil, the flow rate of the spinning oil needs to be controlled to match the production line speed. The flow rate affects production stability and thus fiber quality. Existing defoaming mechanisms are not convenient for controlling the flow rate of the spinning oil after defoaming, reducing the functionality of the defoaming mechanism. At the same time, during the defoaming process, the pressure of the FDY spinning oil passing through the filter plate directly affects the defoaming effect. High pressure will damage the filter screen, while low pressure will allow impurities to penetrate the filter layer. Existing defoaming mechanisms are not convenient for controlling the pressure of the spinning oil passing through the filter plate, reducing the defoaming effect of the defoaming mechanism. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of difficulty in controlling the flow rate of spinning oil after defoaming and difficulty in controlling the pressure of spinning oil when passing through the filter plate, this utility model proposes an extrusion filtration defoaming treatment mechanism for FDY spinning oil.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the extrusion filtration defoaming treatment mechanism for FDY spinning oil agent of this utility model includes a box body, a connecting pipe is connected through the middle of the bottom of the box body, the inside of the connecting pipe is provided with a multi-level slit structure, the bottom flange of the connecting pipe is connected to a flow rate control component, and a pressurization component is connected through the middle of the top of the box body.

[0006] The flow rate control assembly includes a housing with a flange connected to the bottom of the connecting pipe, a threaded cylinder slidably connected to the inner surface of the housing, a ball core fixedly connected to one end of the threaded cylinder, a threaded rod threadedly connected to the inner surface of the threaded cylinder, a transmission rod A fixedly connected to one end of the threaded rod, and a splined connection of one end of the transmission rod A to the output end of the servo motor A.

[0007] The pressurization assembly includes a B transmission rod that is connected through the middle of the top of the housing. The top of the B transmission rod is splined and connected to the output end of the B servo motor. The bottom of the B transmission rod is fixedly connected to a spiral conveying shaft, and the surface of the spiral conveying shaft is slidably connected to the inner surface of the housing.

[0008] Preferably, the threaded cylinder is fixedly connected to both sides with wing plates, the surface of the wing plates is provided with a circular hole, the surface of the circular hole is slidably connected with a guide rod, and one end of the guide rod is fixedly connected to a housing.

[0009] Preferably, a support plate is fixedly connected to the other end of the guide rod, and a threaded rod is rotatably connected to one side of the support plate.

[0010] Preferably, an A motor box is fixedly connected to the other side of the support plate, an A servo motor is fixedly connected to the inner surface of the A motor box, a B motor box is fixedly connected to the surface of the B servo motor, and a housing is fixedly connected to the bottom of the B motor box.

[0011] Preferably, a support ring is fixedly connected to the top of the support plate, the box body overlaps the middle of the top of the support ring, and a support foot is fixedly connected to the bottom edge of the support ring.

[0012] Preferably, an input pipe is connected through to the edge of the top of the housing, and a connecting flange is provided at the edge of the surface of the input pipe.

[0013] The advantages of this utility model are:

[0014] 1. This utility model, through the structural design of the flow rate control component, allows the spinning oil to flow into the outer shell after defoaming through the multi-stage slit structure in the connecting pipe. The A servo motor is then connected to the power supply, causing the A transmission rod to rotate the threaded rod. This rotation is then pushed by the threaded rod along the threaded cylinder, thereby controlling the depth of the ball core into the outer shell and changing the effective flow area within the shell. This enables the defoaming mechanism to control the flow rate of the spinning oil after defoaming, thus improving the functionality of the defoaming mechanism.

[0015] 2. This utility model, through the structural design of the pressurizing component, allows the defoaming mechanism to introduce the spinning oil to be defoamed into the housing via the input pipe. Then, the B servo motor is connected to the power supply, causing the B transmission rod to drive the spiral conveyor shaft to rotate. Because the edge of the spiral blades of the spiral conveyor shaft is in contact with the inner wall of the housing, the spiral conveyor shaft can push the spinning oil out of the connecting pipe during rotation. The rotational speed of the spiral conveyor shaft directly affects the pressure of the spinning oil during extrusion, enabling the defoaming mechanism to control the pressure of the spinning oil as it passes through the filter plate, thus improving the defoaming effect of the defoaming mechanism.

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, an extrusion filtration defoaming treatment mechanism for FDY spinning oil includes a housing 1, a connecting pipe 2 that is connected through the middle of the bottom of the housing 1, a multi-level slit structure inside the connecting pipe 2, a flow rate control component 3 connected to the bottom flange of the connecting pipe 2, and a pressurization component 4 that is connected through the middle of the top of the housing 1.

[0024] The flow rate control assembly 3 includes a housing 301 with a flange connected to the bottom of the connecting pipe 2. A threaded cylinder 302 is slidably connected to the inner surface of the housing 301. A ball core 306 is fixedly connected to one end of the threaded cylinder 302. A threaded rod 303 is threadedly connected to the inner surface of the threaded cylinder 302. A transmission rod 304 is fixedly connected to one end of the threaded rod 303. One end of the transmission rod 304 is splinedly connected to the output end of the servo motor 305.

[0025] The pressurization assembly 4 includes a B transmission rod 401 that is connected through to the middle of the top of the housing 1. The top of the B transmission rod 401 is splined and connected to the output end of the B servo motor 402. The bottom of the B transmission rod 401 is fixedly connected to a screw conveyor shaft 403. The surface of the screw conveyor shaft 403 is slidably connected to the inner surface of the housing 1.

[0026] During operation, through the structural design of the flow rate control component 3, after the spinning oil flows into the outer shell 301 through the multi-stage slit structure in the connecting pipe 2 for defoaming, the A servo motor 305 is connected to the power supply and energized, causing the A transmission rod 304 to drive the threaded rod 303 to rotate. This, in turn, pushes the threaded cylinder 302, whose rotation is restricted, along the threaded rod 303, thereby controlling the depth of the ball core 306 into the outer shell 301. This changes the effective flow area within the outer shell 301, enabling the defoaming mechanism to control the flow rate of the spinning oil after defoaming, thus improving the functionality of the defoaming mechanism. The pressure component 4 is also designed... In this defoaming treatment mechanism, the spinning oil to be defoamed is introduced into the housing 1 through the input pipe 12. Then, the B servo motor 402 is connected to the power supply and powered on, causing the B transmission rod 401 to drive the spiral conveyor shaft 403 to rotate. Since the edge of the spiral blade of the spiral conveyor shaft 403 is in contact with the inner wall of the housing 1, the spiral conveyor shaft 403 can push the spinning oil to be squeezed out from the connecting pipe 2 during rotation. The rotation speed of the spiral conveyor shaft 403 directly affects the pressure of the spinning oil during extrusion, enabling the defoaming mechanism to control the pressure of the spinning oil when passing through the filter plate, thereby improving the defoaming effect of the defoaming mechanism.

[0027] Furthermore, wing plates 5 are fixedly connected to both sides of the threaded cylinder 302. Circular holes are opened on the surface of the wing plates 5, and guide rods 6 are slidably connected to the surface of the circular holes. One end of the guide rods 6 is fixedly connected to the outer shell 301.

[0028] During operation, the rotation of the threaded cylinder 302 can be restricted by the setting of the guide rod 6 and the wing plate 5, thereby improving the stability of the flow rate control component 3.

[0029] Furthermore, a support plate 7 is fixedly connected to the other end of the guide rod 6, and a threaded rod 303 is rotatably connected to one side of the support plate 7;

[0030] During operation, the support plate 7 provides additional support for the flow rate control component 3, which has a large horizontal span, thus improving the stability of the device.

[0031] Furthermore, an A motor box 8 is fixedly connected to the other side of the support plate 7, an A servo motor 305 is fixedly connected to the inner surface of the A motor box 8, a B motor box 9 is fixedly connected to the surface of the B servo motor 402, and a box body 1 is fixedly connected to the bottom of the B motor box 9.

[0032] During operation, the A motor box 8 and the B motor box 9 provide protection, support and fixation for the A servo motor 305 and the B servo motor 402, respectively.

[0033] Furthermore, a support ring 10 is fixedly connected to the top of the support plate 7, the middle of the top of the support ring 10 overlaps the box body 1, and a support leg 11 is fixedly connected to the bottom edge of the support ring 10.

[0034] During operation, the support ring 10 and the support leg 11 are used to support the box 1 to a certain height.

[0035] Furthermore, an input pipe 12 is connected through the top edge of the housing 1, and a connecting flange 13 is provided at the edge of the surface of the input pipe 12.

[0036] During operation, the connecting flange 13 is connected to the external conveying mechanism through the input pipe 12 and the connecting pipe 13, and the spinning oil to be defoamed can be introduced into the inner cylinder of the box 1 through the input pipe 12.

[0037] Working principle: When using this defoaming treatment mechanism, the spinning oil to be defoamed is introduced into the housing 1 through the input pipe 12. Then, the B servo motor 402 is connected to the power supply and energized, causing the B transmission rod 401 to drive the spiral conveyor shaft 403 to rotate. Since the edge of the spiral blade of the spiral conveyor shaft 403 is in contact with the inner wall of the housing 1, the spiral conveyor shaft 403 can push the spinning oil out of the connecting pipe 2 during rotation. The rotation speed of the spiral conveyor shaft 403 directly affects the pressure of the spinning oil during extrusion. After the spinning oil flows into the outer shell 301 after being defoamed by the multi-stage slit structure in the connecting pipe 2, the A servo motor 305 is connected to the power supply and energized, causing the A transmission rod 304 to drive the threaded rod 303 to rotate. The threaded rod pushes the threaded cylinder 302, which is restricted in rotation, to move along the threaded rod 303, thereby controlling the extent to which the ball core 306 penetrates into the outer shell 301, thus changing the effective flow area in the outer shell 301 and controlling the flow rate of the spinning oil.

[0038] The above description is merely 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.
