[0001] The invention relates to the technical field of nylon spinning, and in particular to a nylon spinning oil recovery device and a recovery method thereof. Background Art

[0002] In recent years, the production and environmental pressures faced by many traditional industries in my country have continued to increase, and they have strengthened the optimization of their own industrial structure and the innovation of energy-saving and environmental protection technologies. Among them, the nylon textile industry is included. The current mainstream process of nylon spinning includes chip feeding, nitrogen protection, screw extruder melting, mixing and metering extrusion, box insulation, transportation, metering pump metering, extrusion, component filtration, refinement and stretching, cooling, oil bundling, pre-network, network, high-speed winding, temperature and humidity balance, detection, classification, and packaging. In the monomer suction system and network oil mist suction system of the spinning workshop, some spinning oil will remain.

[0003] Spinning oil is mainly used to prevent static electricity generated by chemical fiber nylon yarns during the production process of chemical fiber nylon, reduce the tension of chemical fiber nylon yarns and improve the cohesion between chemical fiber nylon yarns. It is necessary to oil the chemical fiber nylon yarns, that is, spray organic oil on the chemical fiber nylon yarns through the oil nozzle. The organic oil must be diluted with water before spraying. However, during the spraying process, the organic oil will not be completely absorbed by the chemical fiber nylon yarns, and a certain amount of waste oil and water will be generated. This part of the oil needs to be collected and treated uniformly.

[0004] In the existing technology, the reaction between the waste oil agent and the disinfectant is mostly enhanced by stirring. On the one hand, the efficiency of the traditional stirring rod is low and the function is single; on the other hand, it is easy to cause the extrusion of the waste oil agent, resulting in inventory and environmental pressure. For this reason, we provide a nylon spinning oil recovery device. Summary of the invention

[0012] In order to ensure the accuracy of the dosage of the prepared volume, the stirring rod is further extended to two rows of dispersion rods symmetrically arranged in the solvent box, and a limiting groove is opened on at least one side of the dispersion rod. An extension plate is rotatably connected in the limiting groove. When the stirring rod rotates, the extension plate on at least one row of dispersion rods is in a flat posture.

[0016] A method for recovering nylon spinning oil comprises the following steps:

[0017] Step 1: Inject the recovered oil from nylon spinning into the filter box, and the filter screen swings regularly with quick return characteristics to filter the oil above the filter screen and send it into the tank body; Step 2: Prepare the sterilizing agent in the solvent box, and inject the prepared sterilizing agent into the tank body in a controllable amount; Step 3: Control the rotation of the spiral plate, and at the same time, introduce high-temperature gas into the guide pipe, and the negative pressure formed between the spiral plate and the turning barrel will lift the oil at the bottom of the tank body and inject it from the upper through hole with increased pressure; Step 4: Start the pump body to increase the flow speed of the high-temperature gas, so that it will pass through the hollow base and the guide cavity to the condenser for recovery; Step 5: The discharge pipe at the bottom of the tank body is connected to the recovery tank to recycle the treated oil.

[0018] Compared with the prior art, the present invention provides a nylon spinning oil recovery device and a recovery method thereof, which have the following beneficial effects:

[0019] 1. The nylon spinning oil recovery device quickly draws the oil into the turning barrel from the bottom through-hole of the turning barrel and discharges it around through the through-holes. Compared with the traditional rod stirring, it has a better mixing effect, can accelerate the liquid circulation in the whole tank body, prevents the occurrence of dead corners, and is easier to clean and maintain than the traditional bolt connection structure. At the same time, it is not only limited to the stirring function, but also a guide pipe is welded along the spiral line of the outer edge of the spiral plate. The high-temperature gas or liquid supplied from the outside can flow upward in the turning barrel through the guide pipe, thereby heating and sterilizing the turned oil and promoting the mixing of the bactericide and the oil, further improving the sterilization effect.

[0020] 2. The nylon spinning oil recovery device is provided with a stirring rod in the solvent box to promote the speed and uniformity of solvent mixing and ensure the continuous supply of bactericide. The stirring rod is also extended to the filter box where a filter part is provided. The filter part is driven by the stirring rod to remove impurities. Compared with fixed filtration, it has higher efficiency and anti-clogging effect.

[0021] 3. When the filter screen is filtering the upper layer of oil, the nylon spinning oil recovery device will first slowly rotate and tilt to promote the flow of the oil, thereby increasing the filtering speed. Then, the elastic volute will quickly reverse and quickly replace the oil to prevent the oil from accumulating or impurities from getting stuck in the rotating joint. At the same time, rapid rotation can prevent the filter screen from being blocked, thereby further increasing the filtering speed of the oil, improving the subsequent recovery efficiency, and greatly reducing inventory pressure.

[0022] 4. The nylon spinning oil recovery device guides the movement trajectory of the high-temperature fluid. We use the high temperature of the high-temperature fluid to heat the pre-treated oil again, improve its fluidity, and further improve the filtration speed and anti-clogging effect.

[0023] 5. The nylon spinning oil recovery device extracts fungicide from all around through the blades in the circulation cylinder and discharges it from the duckbill structure. On the one hand, it improves the mixing effect of the fungicide. On the other hand, since the duckbill structure suddenly becomes smaller, the discharged fungicide has a higher flow rate, which can flush the top wall of the solvent box, prevent the existence of residual particles, and ensure the proportion accuracy of the next solution preparation.

[0024] 6. The nylon spinning oil recovery device, through the opening and rotation of the expansion plate, will drive more fungicide to create a surge, thereby flushing the side wall of the solvent box, preventing fungicide particles from remaining on the side wall, etc., effectively improving the mixing effect, and the side of the unexpanded expansion plate will hit the liquid surface of the fungicide, thereby breaking up the lumps that may not be completely dissolved in the fungicide, further ensuring the mixing effect and improving the subsequent mixing quality with the oil.

[0025] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The present invention relieves the oil storage pressure by setting a pre-treatment filter box, and can perform preliminary treatment on the recovered oil through the internal filter part, thereby improving the subsequent oil recovery efficiency and reducing inventory pressure, and uses the turning barrel and spiral plate to realize the turning of the oil, thereby improving the multi-functionality of oil mixing and processing while facilitating the maintenance of subsequent equipment.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Example:

[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 A nylon spinning oil recovery device comprises: a cylindrical tank body 1 with a discharge pipe 101 at the bottom, and a turning barrel 2 with through holes 201 evenly distributed on the outer shell. The through holes 201 are arranged in a vertical row and then in a circular array on the turning barrel 2, so that the arrangement of the through holes 201 is more uniform, thereby improving the uniformity of subsequent turning. There are three or four groups of spiral plates 302 connected to the inside of the tank body 1 in a circular manner around the axis of the tank body 1, and the spiral plates 302 are connected to the turning barrel 2. As the spiral plates 302 rotate, the spiral plates 302 rotate. The rotation can form suction inside the turning barrel 2, so that the oil agent is quickly drawn into the turning barrel 2 from the bottom through-hole of the turning barrel 2, and discharged from the through-hole 201 to the surroundings. Compared with the traditional rod stirring, it has a better mixing effect, and can accelerate the liquid circulation in the whole tank body 1 to prevent the occurrence of dead corners. It is also easier to clean and maintain than the traditional bolt connection structure. At the same time, it is not limited to the stirring function. It is more powerful, and the spiral line along the outer edge of the spiral plate 302 is welded with a guide The high-temperature gas or liquid supplied from the outside can flow upward in the turning barrel 2 through the guide pipe 301, thereby heating and sterilizing the turned oil agent and promoting the mixing of the bactericide and the oil agent, further improving the sterilization effect; a filter box 4 for preliminary cleaning and recovery of lint and broken nylon yarn in the oil agent and a solvent box 5 specially used for preparing the bactericide are fixedly connected to the top of the tank body 1. Both sets of boxes are connected to the tank body 1 through the valve body. The valve body is opened and closed by the central control room to achieve the fixed mixing of the waste oil agent and the bactericide. The solvent box 5 is provided with a stirring rod 6 for promoting the speed and uniformity of solvent mixing and ensuring the continuous supply of bactericidal agent. The stirring rod 6 also extends to the filter box 4 where a filter part is provided. The filter part is driven by the stirring rod 6 to remove impurities, which has higher efficiency and anti-clogging effect than fixed filtration. A driving part for driving the spiral plate 302 and the stirring rod 6 to rotate is fixedly connected to the top of the tank body 1.

[0039] In the above scheme, the oil storage pressure is relieved by setting up a pre-treatment filter box 4, and the recovered oil can be preliminarily treated through the internal filter part, so as to improve the subsequent oil recovery efficiency and reduce the inventory pressure, and the turning of the oil is achieved by using the turning barrel 2 and the spiral plate 302, so as to facilitate the maintenance of the subsequent equipment while improving the multifunctionality of oil mixing and processing.

[0040] Reference Figure 2 , Figure 3 Figure 4 and Figure 6In the nylon spinning oil recovery device, the driving part includes: a motor 9 fixedly connected to the top of the tank body 1, a driving shaft 901 is provided at the output end of the motor 9, the driving shaft 901 extends to the top of the motor 9 and is fixedly connected to a driving disk 902, and the driving disk 902 is provided with a quarter of a conical tooth, and a bevel gear 602 is fixedly connected to the stirring rod 6. When the bevel gear 602 is engaged with the conical teeth on the driving disk 902, the stirring rod 6 will be driven to rotate a certain angle. When the bevel gear 602 is disengaged from the conical teeth on the driving disk 902, the stirring rod 6 will not be driven by the driving disk 902; at this time, there is a bevel gear 602 fixedly connected to the stirring rod 6. The elastic volute 601, wherein the side wall of the filter box 4 is fixedly connected with the energy storage box 403, the elastic volute 601 is arranged in the energy storage box 403, and the other end of the elastic volute 601 is fixedly connected to the inner wall of the energy storage box 403, that is, when the bevel gear 602 is disengaged from the conical teeth on the drive disk 902, the energy stored in the elastic volute 601 caused by the previous rotation of the stirring rod 6 will be released, so that the stirring rod 6 is instantly reversed, and the reversal speed is much greater than the speed driven by the drive disk 902 to rotate, so that the stirring rod 6 has a quick return characteristic, and this characteristic is applied to the subsequent structure, and we will find that it has two effects.

[0041] The first one, refer to Figure 3 , Figure 4 and Figure 6 We specifically design the filter part so that it can utilize the motion characteristics of the stirring rod 6. The specific design of the filter part includes a flip frame 7 fixedly connected to one end of the stirring rod 6, a filter screen 701 is fixedly connected to the flip frame 7, and the mesh number of the filter screen 701 is about 800 to ensure the effectiveness of its filtration. The interior of the filter box 4 is a cylindrical cavity, the axis of the stirring rod 6 coincides with the axis of the cylindrical cavity, and both ends of the flip frame 7 are fixedly connected with an arc plate 702, and the arc plate 702 fits the cylindrical surface of the cylindrical cavity. The bottom of the cylindrical cavity is connected to the tank body 1 through the guide channel 402. When the filter screen 701 filters the upper layer of oil, it will first slowly rotate and tilt to promote the flow of the oil, thereby increasing its filtering speed. Then, it will quickly reverse under the action of the elastic volute 601, and quickly displace the oil to prevent the oil from accumulating or impurities from getting stuck in the rotating joint. At the same time, the rapid rotation can prevent the filter screen 701 from being blocked, thereby further increasing the filtering speed of the oil, improving the subsequent recovery efficiency, and greatly reducing the inventory pressure.

[0042] In addition, refer to Figure 8A hollow base 401 is provided below the filter box 4, and the hollow base 401 is connected to the guide pipe 301. A pump body 10 is fixedly connected to the top of the tank body 1, and the input end of the pump body 10 is connected to the hollow base 401 through a first pipe 11, and the output end of the pump body 10 is fixedly connected to the second pipe 12. By guiding the movement trajectory of the high-temperature fluid, we again use the high temperature of the high-temperature fluid to heat the pretreated oil agent, improve its fluidity, and further improve the filtration speed and anti-clogging effect.

[0043] Reference Figure 3 and Figure 7 On the basis of the above structure, it also includes: a circulation cylinder 501, the top of which is duckbill-shaped, and the bottom of which is circumferentially provided with a plurality of circulation grooves 506, which is fixedly connected to the solvent box 5; a booster shaft 503 rotatably connected to the circulation cylinder 501, and a plurality of blades 504 are evenly distributed on the booster shaft 503 in a circumferential manner, wherein a guide cavity 502 is provided on the bottom wall of the solvent box 5, and the guide cavity 502 is arranged directly below the circulation cylinder 501, and the guide cavity 502 is connected to the second pipeline 12, and the booster shaft 503 extends to the guide cavity 502 and is provided with a turbine blade 505, which further guides the high temperature The fluid flow turbine is used, and the pump body 10 is used to pressurize the fluid, so that it pushes the turbine blade 505 to move, thereby driving the boost shaft 503 to rotate. As the boost shaft 503 rotates rapidly, the bactericide can be extracted from all around through its blades 504 in the circulation cylinder 501 and discharged from the duckbill structure. On the one hand, the mixing effect of the bactericide is improved. On the other hand, since the duckbill structure suddenly becomes smaller, the discharged bactericide has a higher flow rate, which can flush the top wall of the solvent box 5, prevent the existence of residual particles, and ensure the proportional accuracy of the next preparation of the liquid medicine.

[0044] Another reference Figure 2 , Figure 3 , Figure 4 and Figure 6The stirring rod 6 extends into the solvent box 5 and two rows of dispersion rods 8 are symmetrically arranged. A limiting groove 801 is provided on at least one side of the dispersion rod 8. An extension plate 803 is rotatably connected in the limiting groove 801. When the stirring rod 6 rotates, the extension plate 803 on at least one row of dispersion rods 8 is in a flat posture. The limiting groove 801 is a quarter-cylindrical groove, and the intersection surface of the quarter-cylindrical groove is arranged obliquely to ensure that the extension plate 803 can be stably unfolded and retracted. A positioning shaft 802 is fixedly connected in the limiting groove 801, and a rotating seat 804 is fixedly connected to the expansion plate 803. The rotating seat 804 is rotatably connected to the positioning shaft 802, and when the expansion plate 803 is flat, at least one side of the expansion plate 803 and at least one group of cross-sectional surfaces of the limiting groove 801 are aligned. Similarly, when the conical teeth of the stirring rod 6 mesh and rotate, the normal dispersion rod 8 can be used to mix and stir the liquid medicine in the solvent tank 5. When the stirring rod 6 returns sharply, such as counterclockwise, the expansion plate 803 on the right will open. Similarly, when it returns sharply clockwise, the expansion plate 803 on the left will open. As the expansion plate 803 opens and rotates, it will drive more bactericide to surge, thereby flushing the side wall of the solvent tank 5 to prevent residual bactericide particles on the side wall, etc., effectively improving the mixing effect, and the side where the expansion plate 803 is not unfolded will slam the liquid surface of the bactericide, thereby breaking up the incompletely dissolved lumps that may exist in the bactericide, further ensuring the mixing effect and improving the subsequent mixing quality with the oil agent.

[0045] In addition, a mounting plate 303 is rotatably connected to the inner wall of the top of the tank body 1, the spiral plate 302 and the guide tube 301 are fixedly connected to the mounting plate 303, and the guide tube 301 passes through the center line of the mounting plate 303 and is connected to the hollow base 401. A second gear 3 is fixedly connected to the mounting plate 303, and a first gear 903 is fixedly connected to the other end of the drive shaft 901. The first gear 903 is meshed with the second gear 3. The drive shaft 901 can also drive the spiral plate 302 to rotate to extract the oil agent for flipping and mixing.

[0046] There are multiple groups of guide pipes 301, which are evenly distributed in a circle in the tank body 1. The bottom inner wall of the tank body 1 is provided with an annular air supply pipe 304. The bottom of the guide pipes 301 are connected to the annular air supply pipe 304, and the annular air supply pipe 304 is used for unified air supply to ensure the stability of air supply and the uniformity of heating of the turning material mixing.

[0047] A method for recovering nylon spinning oil comprises the following steps:

[0048] Step 1: Inject the recovered oil from nylon spinning into the filter box 4, and the filter screen 701 swings regularly with a quick return characteristic, so that the oil above the filter screen 701 is filtered and sent into the tank body 1. Through the pre-storage treatment of the oil, the inventory pressure is reduced and the subsequent mixing effect is improved;

[0049] Step 2: prepare a sterilizing agent in the solvent box 5, wherein the sterilizing agent is mainly a dynamically proportioned mixture of isothiazolinone-bronopol-ethylene glycol, and inject the prepared sterilizing agent into the tank body 1 in a controllable amount;

[0050] Step 3: Control the spiral plate 302 to rotate, and at the same time, introduce high-temperature gas into the flow guide tube 301, so that the oil at the bottom of the tank body 1 is lifted and injected from the upper through hole 201 through the negative pressure formed between the spiral plate 302 and the turning barrel 2;

[0051] Step 4: Start the pump body 10 to increase the flow velocity of the high-temperature gas so that the gas passes through the hollow base 401 and the guide cavity 502 and is sent to the condenser 13 for recovery;

[0052] Step 5: The discharge pipe 101 at the bottom of the tank body 1 is connected to a recovery tank to recycle the treated oil.
