[0040] like Figs. 1 to 4 As shown in the embodiment of this utility model, a lubrication and cooling device for a chemical fiber spinning system is introduced, including a cooling device 1 and an oil mist lubrication device 2. The cooling device 1 is provided with an installation platform 111, and the oil mist lubrication device 2 is fixed on the installation platform 111 by an installation component 4.

[0041] With the above configuration, by setting the mounting platform 111 on the cooling device 1 and mounting the oil mist lubrication device 2 on the mounting platform 111 through the mounting component 4, the two devices are integrated into a compact whole, reducing the floor space occupied and thus achieving the purpose of saving space.

[0042] In one embodiment of this utility model, a mounting bracket is provided on the cooling device 1. The mounting bracket includes multiple mounting legs, which are respectively connected to the cooling device 1 and extend upward from the cooling device 1; and a mounting base, which is connected to the top of each mounting leg, and the top of the mounting base forms a mounting platform 111.

[0043] In another preferred embodiment of the present invention, the cooling device 1 includes a box-type first liquid storage structure 110 for storing cooling medium, and the top of the first liquid storage structure 110 forms an installation platform 111 connected to the installation assembly 4; by utilizing the original first liquid storage structure 110 of the cooling device 1 to form the installation platform 111, the equipment layout is compact and orderly, which facilitates installation, maintenance and management.

[0044] In an embodiment of this utility model, the cooling device 1 includes a circulation component 120, which is connected to the first liquid storage structure 110 and forms a circulation liquid path. The circulation component 120 is disposed on the mounting platform 111 and is disposed at a certain distance from one side edge of the mounting platform 111. The mounting component 4 is disposed in the interval area.

[0045] In this embodiment of the present invention, the circulation component 120 and the other side edge of the mounting platform 111 are also spaced at a certain distance to form another interval area. A control device 3 is provided on the other interval area to control the operation of the oil mist lubrication device 2 and the cooling device 1.

[0046] With the above setup, technicians can operate the two devices separately through a single control device 3, which is convenient for technicians and reduces the overall purchase and maintenance costs of the equipment. In addition, the control device 3 and the oil mist lubrication device 2 are integrated on the mounting platform 111 of the cooling device 1, making the equipment structure compact and significantly reducing the overall footprint.

[0047] In one embodiment of this utility model, the mounting structure includes a horizontally extending base and a connecting arm extending upward from one end of the base, forming an L-shaped structure; multiple mounting structures are arranged along the periphery of the oil mist lubrication device 2, each connecting arm is connected to the periphery wall of the mounting structure, and the base is connected to the mounting platform 111.

[0048] In an embodiment of this utility model, the mounting component 4 includes a first mounting structure 410 connected to the mounting platform 111; and a second mounting structure 420 connected to the oil mist lubrication device 2, wherein the second mounting structure 420 is connected to the first mounting structure 410. By setting separate first mounting structure 410 and second mounting structure 420, it is convenient to install the oil mist lubrication device 2 on the mounting platform 111.

[0049] In embodiments of this utility model, the first mounting structure 410 and the second mounting structure 420 are connected by welding, and / or screw connection, and / or riveting connection.

[0050] In the embodiments of this utility model, the first mounting structure 410 and the second mounting structure 420 are located at a height between the oil mist lubrication device 2 and the mounting platform 111.

[0051] In the embodiments of this utility model, two first mounting structures 410 are spaced apart along a horizontal first direction, and at least two second mounting structures 420 are spaced apart along a horizontal second direction. Both are arranged within the space between the two first mounting structures 410 to form a frame structure; the first direction is perpendicular to the second direction.

[0052] Through the above-mentioned setup, the stable support frame formed by the cooperation of the two first mounting structures 410 and the two second mounting structures 420 greatly enhances the stability and firmness of the installation; it enables the mounting component 4 to withstand greater loads and vibrations, thereby ensuring the stable operation of the oil mist lubrication device 2 during the chemical fiber spinning process; and the frame structure mounting component 4 is designed with a certain degree of versatility, which can adapt to different models and specifications of oil mist lubrication devices 2 and the mounting platform 111 of cooling device 1, helping to reduce the cost of equipment replacement and maintenance, and improve the flexibility and scalability of the equipment.

[0053] In an embodiment of this utility model, the oil mist lubrication device 2 includes a columnar second liquid storage structure 210, which is vertically arranged, and each second mounting structure 420 is connected to the bottom of the second liquid storage structure 210; preferably, the second mounting structures 420 are symmetrically arranged on both sides of the central axis of the second liquid storage structure 210; preferably, the number of second mounting structures 420 is two.

[0054] In embodiments of this utility model, each first mounting structure 410 includes a first connecting portion 411, which extends in a strip shape along a second direction and is connected to the mounting platform 111; a first support portion 412, which extends upward from the first connecting portion 411; and a second mounting structure 420 including a second connecting portion 421 extending along a first direction and connected to the oil mist lubrication device 2. The two ends of the second connecting portion 421 in the first direction are respectively connected to the extension ends of the corresponding first support portion 412, and there is a certain distance between the second connecting portion 421 and the first connecting portion 411.

[0055] With the above configuration, by connecting the second connecting part 421 to the first supporting part 412, while ensuring the stability of the connection, a clearance space is formed between the second connecting part 421 and the first connecting part 411. When the installation structure and the oil mist lubrication device 2 are subjected to vibration or temperature changes and expand or contract, the second connecting part 421 can absorb part of the impact force through a certain degree of elastic deformation, which helps to reduce stress concentration caused by vibration or temperature changes, and further ensures the stable operation of the oil mist lubrication device 2 in the chemical fiber spinning process.

[0056] In this embodiment of the present invention, the first connecting part 411 is a strip that fits into the mounting platform 111, and the second connecting part 421 is a strip that fits into the bottom of the oil mist lubrication device 2.

[0057] In the embodiments of this utility model, the edges of the two first connecting parts 411 that are farther apart are respectively connected to the first supporting part. The first supporting part 412 is a strip-shaped plate that extends continuously along the second direction, and the plate surface of the first supporting part 412 is vertically arranged.

[0058] In the embodiments of this utility model, two second mounting structures 420 are symmetrically arranged on both sides of the vertical line in the oil mist lubrication device 2; each second connecting part 421 has a downwardly extending second support part 422 on the adjacent side, and the two ends of the second support part 422 in the first direction are respectively connected to the corresponding first support part 412.

[0059] Through the above settings, the force balance of the oil mist lubrication device 2 on the mounting assembly 4 is ensured, avoiding equipment tilting or vibration caused by uneven force. In addition, by making the second support parts 422 on the adjacent sides of the two second connecting parts 421 form an L-shaped second mounting structure 420, the structural strength of the second mounting structure 420 is effectively improved. Furthermore, the second support parts 422 reinforce the adjacent sides of the second connecting parts 421, and the far side is suspended. When the oil mist lubrication device 2 is vibrated, the far side area can achieve a vibration reduction effect through a certain degree of elastic deformation.

[0060] In this embodiment of the invention, the lower end of the second support portion 422 abuts against the top of the two first connecting portions 411 respectively, thereby further improving the stability of the connection.

[0061] In a specific embodiment of this utility model, the oil mist lubrication device 2 includes a columnar second liquid storage structure 210 with its axis vertically arranged, and a second connecting part 421 connected to the bottom of the second liquid storage structure 210, and the two second connecting parts 421 are respectively symmetrically arranged on both sides of the axis of the second liquid storage structure 210.

[0062] In an embodiment of this utility model, the mounting component 4 includes a horizontally extending second mounting structure 420 and a third mounting structure 430 extending upward from the second mounting structure 420; the oil mist lubrication device 2 includes a second liquid storage structure 210 for storing oil and fixedly mounted on the top of the second mounting structure 420; and an oil mist tube assembly 220 disposed on the top of the second liquid storage structure 210 and connected to the third mounting structure 430.

[0063] In this embodiment of the present invention, by providing a third mounting structure 430, the mounting component 4 supports the oil mist tube assembly 220. At the same time, the third mounting component 4 is connected to the second mounting component 4, which can ensure that the oil mist tube assembly 220 is always relatively stationary with respect to the second liquid storage structure 210. This prevents the oil mist tube assembly 220 from vibrating during operation, which could lead to leakage or even breakage at the connection between the oil mist tube assembly 220 and the second liquid storage structure 210.

[0064] In this embodiment of the present invention, an oil mist generator 250 is installed on the top of the second liquid storage structure 210, and the oil mist tube assembly 220 includes a main air passage 221 and a secondary air passage 222 connected in parallel. The main air passage 221 is connected to the oil mist generator 250, and the secondary air passage 222 is connected to the third mounting structure 430. The main air passage 221 is directly connected to the oil mist generator 250 and is used to guide the oil mist generated by the oil mist generator 250 downstream. The secondary air passage 222 provides additional airflow to ensure that the oil mist is delivered to the bearing at a stable flow rate, thereby achieving a more precise lubrication effect. At the same time, the secondary air passage 222 is specifically supported to reduce the complexity of the mounting component 4 structure and the manufacturing cost while ensuring the stability of the oil mist tube assembly 220.

[0065] In this embodiment of the present invention, two third mounting structures 430 are spaced apart in the second direction and are respectively connected to the corresponding second mounting structures 420; the auxiliary gas passage 222 extends along the second direction, and the two third mounting structures 430 are respectively provided with assembly structures connected to the auxiliary gas passage 222; preferably, the assembly structure is U-shaped, the U-shaped assembly structure is sleeved on the auxiliary gas passage 222, and the two ends of the U-shaped assembly structure are respectively connected to the third mounting structure 430.

[0066] In this embodiment of the present invention, the third connecting part 431 is provided with a plurality of connecting holes 450 arranged in a vertical direction; the assembly structure can be selectively connected to the connecting holes 450, so that the assembly structure can be flexibly adjusted in height according to the location of the auxiliary air passage 222.

[0067] In the embodiments of this utility model, the two third mounting structures 430 include vertically extending strip-shaped third connecting portions 431, the plate surface of the third connecting portions 431 is parallel to the second direction, and the auxiliary air passage 222 is in close contact with the third connecting portions 431.

[0068] In an embodiment of this utility model, the two adjacent third connecting portions 431 are respectively connected to a third support portion 432 that extends continuously in the vertical direction, and the lower end of the third support portion 432 is respectively connected to the corresponding second mounting structure 420; preferably, the third support portion 432 is a strip-shaped plate with its surface parallel to the first direction.

[0069] In this embodiment of the present invention, the connection position of the third mounting structure 430 and the second mounting structure 420 is close to the connection position of the second mounting structure 420 and the first mounting structure 410. The L-shaped third mounting structure 430 can improve the structural strength of the second connecting part 421, avoid the end deformation of the second connecting part 421, and prevent the connection between the second connecting part 421 and the first support part 412 from breaking due to large stress, thereby improving the overall structural strength of the mounting assembly 4.

[0070] In this embodiment of the present invention, the oil mist lubrication device 2 is further provided with a pressure control component 230, which is connected to the oil mist tube assembly 220 and is used to control the on / off valve on the oil mist tube assembly 220 according to the monitored pressure value; the mounting component 4 also includes a fourth mounting structure 440 connected to the pressure control component 230, at least two third mounting structures 430 are arranged side by side in the horizontal direction, and the fourth mounting structure 440 is connected to the top end of all the third mounting structures 430; preferably, each third mounting structure 430 is arranged at equal intervals below the fourth mounting structure 440; another preferred embodiment is that the number of third mounting structures 430 is 2, and the top ends of the two third mounting structures 430 are respectively connected to the two ends of the fourth mounting structure 440.

[0071] With the above settings, by setting the pressure control component 230, the oil mist lubrication device 2 can flexibly control the delivery of oil mist according to the monitored pressure value. When the oil mist pressure is greater than or equal to the preset value, the on-off valve is controlled to open; when the oil mist pressure is less than the preset value, the on-off valve is controlled to close. In addition, by adding a fourth mounting structure 440 corresponding to the pressure control component 230 to the mounting structure, compared with the solution of directly fixing it to the oil mist tube assembly 220, the fourth mounting structure 440 can more firmly fix the pressure control component 230 and prevent it from falling off. Furthermore, the third mounting structure 430 and the fourth mounting structure 440 together form a support frame, which improves the structural stability of the mounting component 4.

[0072] In this embodiment of the present invention, the pressure control component 230 is connected to the main air passage 221; the on / off valve is located upstream of the connection position between the main air passage 221 and the second liquid storage structure 210, and the connection position between the pressure control component 230 and the main air passage 221 is located between the on / off valve of the main air passage 221 and the second liquid storage structure 210; so that after the second liquid storage structure 210 provides sufficient pressure of oil mist into the main air passage, the pressure control component 230 controls the on / off of the main air passage 221, so as to prevent the oil mist concentration output by the main air passage 221 from being low when the oil mist lubrication device 2 first starts working, resulting in poor lubrication effect on the roller bearing.

[0073] In an embodiment of this utility model, the fourth mounting structure 440 includes a fourth connecting portion 441 connected to the pressure control assembly 230. The fourth connecting portion 441 extends along a second direction and is a strip-shaped plate vertically arranged on the plate surface. A fourth support portion 442, horizontally arranged on the plate surface, is connected to the bottom edge of the fourth connecting portion 441. The bottom surface of the fourth support portion 442 is connected to the top surface of the third mounting structure 430. Specifically, the top surfaces of both the third connecting portion 431 and the third support portion 432 are connected to the bottom surface of the fourth support portion 442.

[0074] In the embodiments of this utility model, the length of the control device 3 in the horizontal second direction is equal to or substantially equal to that of the mounting platform 111, and the second direction is perpendicular to the first direction.

[0075] It should be noted that due to factors such as process error and installation error, there is a small, negligible difference between the length of the control device 3 and the mounting platform 111 in the second direction. As long as it does not affect the stability of the installation of the control device 3, it can be regarded as the length of the control device 3 in the horizontal second direction being basically equal to that of the mounting platform 111.

[0076] In the embodiments of this utility model, the cooling medium stored in the first liquid storage structure 110 is water or oil; preferably, the cooling medium stored in the first liquid storage structure 110 is oil.

[0077] In an embodiment of this utility model, the cooling device 1 includes a circulation component 120, which is disposed on the mounting platform 111 and cooperates with the first liquid storage structure 110 to form a circulation liquid path; the oil mist lubrication device 2 is disposed at intervals on both sides of the mounting platform 111, and the circulation component 120 is located in the interval area between the oil mist lubrication device 2 and the control device 3.

[0078] In an embodiment of this utility model, the cooling device 1 includes a cooling medium adding component 140. The liquid outlet of the cooling medium adding component 140 is connected to the first liquid storage structure 110. The cooling medium adding component 140 is disposed in the interval area and is offset from the circulation component 120.

[0079] In an embodiment of this utility model, the installation platform 111 has an opening in the interval area that communicates with the interior of the first liquid storage structure 110, and a first cover plate 150 is fastened to the opening. The cooling medium adding component 140 is connected to the first cover plate 150.

[0080] In an embodiment of this utility model, the oil mist lubrication device 2 includes an oil mist tube assembly 220 for guiding oil mist; a first pressure gauge 240 for monitoring and displaying the air pressure value of the oil mist tube assembly 220; and a control panel 310 is provided on the control device 3, with the first pressure gauge 240 mounted on the control device 3 and located on the same side wall of the control device 3 as the control panel 310.

[0081] With the above configuration, by placing the first pressure gauge 240 and the control panel 310 on the same side wall of the control device 3, technicians can conveniently view the equipment operating parameters and the air pressure value of the oil mist pipe assembly 220 at the same time when inspecting and maintaining the equipment.

[0082] In this embodiment of the present invention, the first pressure gauge 240 is connected to the oil mist tube assembly 220 through a measuring tube 241. The control device 3 has a communication port on the side wall facing the oil mist lubrication device 2. One end of the measuring tube 241 extends into the control device 3 through the communication port and is connected to the first pressure gauge 240. By extending the measuring tube 241 into the control device 3, the connection between the measuring tube 241 and the first pressure gauge 240 is hidden and protected, avoiding contact with external objects, which could lead to wear or even cracking at the connection point.

[0083] In this embodiment of the present invention, the peripheral wall of the communication port of the control device 3 is connected to the measuring tube 241 to reinforce the measuring tube 241 and ensure that the part of the measuring tube 241 located inside the control device 3 is always relatively stationary with respect to the first pressure gauge 240 installed on the control device 3, thereby further ensuring the stability of the connection between the measuring tube 241 and the first pressure gauge 240.

[0084] In this embodiment of the invention, the oil mist lubrication device 2 and the control device 3 are arranged along the first horizontal direction, and the first pressure gauge 240 and the control panel 310 are set on the side wall of the control device 3 facing the first direction; this further facilitates the operation of the control device 3 by technicians, and leaves the two sides of the cooling device 1 in the second direction free for other devices, thus improving space utilization.

[0085] In this embodiment of the invention, the first pressure gauge 240 is positioned above the control panel 310. Preferably, the vertical height of the center of the control panel 310 from the ground is greater than or equal to 85cm and less than or equal to 150cm; the vertical height of the center of the first pressure gauge 240 from the ground is greater than or equal to 100cm and less than or equal to 160cm; more preferably, the vertical height of the center of the control panel 310 from the ground is greater than or equal to 100cm and less than or equal to 130cm; and the vertical height of the center of the first pressure gauge 240 from the bottom surface is greater than or equal to 140cm and less than or equal to 150cm.

[0086] By limiting the height of the control panel 310, it is positioned so that technicians can easily reach it with their arms hanging naturally and their elbows slightly bent when standing. This ensures that technicians can conveniently operate the control panel 310 while standing. Furthermore, by limiting the height of the first pressure gauge 240, it is positioned so that personnel can clearly see it without excessive head-down or head-up while standing. In the preferred embodiment, based on the average height of adult males being 174 cm and adult females being 160 cm, and the height difference between the top of the head and the center of the eyebrows generally being around 10 cm, limiting the center height of the control panel 310 and the first pressure gauge 240 allows most technicians to view the first pressure gauge 240 and the display components on the control panel 310 by slightly lowering their heads or looking straight ahead. Their line of sight can simultaneously cover the display components and the dial of the first pressure gauge 240 without needing to look up or turn their heads. This allows technicians to understand the overall working status of the lubrication and cooling equipment by combining both, and facilitates the entry of relevant work data into their record sheets, effectively improving work efficiency.

[0088] In this embodiment of the invention, the oil mist generator 250 is installed on top of the second liquid storage structure 210. An oil guide pipe is provided inside the second liquid storage structure 210. The upper end of the oil guide pipe extends outward through an opening at the bottom of the second liquid storage structure 210 and connects to the oil mist generator 250, thereby guiding the oil in the second liquid storage structure 210 to the oil mist generator 250 at the top. In this embodiment of the invention, the cooling device 1 includes a circulation assembly 120 and a second pressure gauge 160 disposed on the circulation assembly 120. Both the first pressure gauge 240 and the second pressure gauge 160 are equipped with dials displaying pressure values, and the two dials face the same direction. This allows technicians to simultaneously monitor the pressure readings of both devices and the operating status displayed on the control panel 310 from the same direction, further improving work efficiency.

[0089] In this embodiment of the invention, the projection of the dial of the second pressure gauge 160 in its orientation is misaligned with that of the control device 3 to prevent the control device 3 from obstructing the dial of the second pressure gauge 160.

[0090] In this embodiment of the invention, the oil mist lubrication device 2 and the control device 3 are arranged along a horizontal first direction; the projection of at least part of the circulation component 120 in the first direction is misaligned with that of the control device 3; the second pressure gauge 160 is installed on the misaligned part of the circulation component 120, and the dials of the second pressure gauge 160 and the first pressure gauge 240 both face the first direction; by limiting the installation position of the second pressure gauge 160, the second pressure gauge 160 and the control device 3 are misaligned, allowing technicians to stand in front of the control panel 310 and observe both pressure gauges and the control panel 310 simultaneously without moving.

[0091] In this embodiment of the invention, a heat exchanger 130 is connected in series on the circulation pipe 122 to reduce the temperature of the flowing oil and improve the cooling efficiency of the cooling medium on the roller and / or bearing. Preferably, the oil mist lubrication device 2 and the control device 3 are arranged on the top of the first liquid storage structure 110 along a horizontal first direction, and the heat exchanger 130 is located on the horizontal second direction side of the first liquid storage structure 110, and the heat exchanger 130 extends along the first direction, with the first and second directions perpendicular to each other, so that the equipment layout is more compact and reasonable.

[0092] In this embodiment of the present invention, the two side walls of the control device 3 in the second direction are respectively flush with the side wall of the first liquid storage structure 110; the circulation pipe 122 extends beyond the side wall of the first liquid storage structure 110 in the second direction and is located above the heat exchanger 130; the second pressure gauge 160 is connected to the portion of the circulation pipe 122 located above the heat exchanger 130.

[0093] In this embodiment of the present invention, the liquid inlet of the heat exchanger 130 is located at the top near the control device 3; the circulation pipe 122 is located above the heat exchanger 130 in the first pipe section and the second pipe section. The first pipe section extends along the first direction, and the second pipe section extends downward from the end of the first pipe section and communicates with the liquid inlet of the heat exchanger 130. The second pressure gauge 160 is connected to the middle of the first pipe section. This allows the second pressure gauge 160 to be positioned closer to the control device 3, and the control device 3 will not obstruct the second pressure gauge 160. This allows a technician standing directly in front of the control device 3 to observe the reading of the second pressure gauge 160 by tilting their viewing angle in the second direction, thus enabling convenient and intuitive observation of the reading of the second pressure gauge 160.

[0094] In an embodiment of this utility model, a first liquid level gauge is provided in the first liquid storage structure 110, a second liquid level gauge is provided in the second liquid storage structure 210, a first display component 311 of the control device 3 is electrically connected to the first liquid level gauge, and a second display component 313 is electrically connected to the second liquid level gauge.

[0095] In an embodiment of this utility model, the heat exchanger 130 includes a cooling medium channel and a heat exchange medium channel, the cooling medium channel being connected in series with the circulation pipe 122; the heat exchange medium channel is used to guide the heat exchange medium that cools the cooling medium; a first thermometer is provided on the heat exchange medium channel, and the first thermometer is electrically connected to the control device 3 and a display component.

[0096] In an embodiment of this utility model, the circulation component 120 includes a circulation pump 121 and a circulation pipe 122. The circulation pump 121 is installed on the top of the first liquid storage structure 110, and the circulation pipe 122 is connected to the outlet end of the circulation pump 121. Preferably, the circulation pump 121 includes a pump chamber containing an impeller for stirring the liquid, and the circulation pipe 122 is connected to the pump chamber. A motor assembly is disposed outside the pump chamber and is drivenly connected to the impeller. The motor assembly is disposed near the control box to facilitate electrical connection between the control box and the motor. Preferably, the inlet end of the circulation pipe 122 is connected to the outlet end of the circulation pump 121, and the outlet end of the circulation pipe 122 is connected to the first liquid storage structure 110 to form a circulation path.

[0097] In an embodiment of this utility model, an oil suction filter is provided inside the first liquid storage structure 110, and an oil suction pipe is connected to the outlet end of the oil suction filter. The oil suction pipe extends to the top of the first liquid storage structure 110 and is connected to the circulation pump 121.

[0098] In an embodiment of this utility model, a one-way valve is provided on the circulation pipe 122.

[0099] In this embodiment of the present invention, a bypass regulating pipe 170 is branched onto the circulation pipe 122. The liquid outlet of the bypass regulating pipe 170 is connected to the top of the first liquid storage structure 110, or extends into the interior of the first liquid storage structure 110 through the top opening of the first liquid storage structure 110. A bypass regulating valve with an adjustable opening is provided on the bypass regulating pipe 170. The flow rate of the oil flowing through the bypass regulating pipe 170 is adjusted by changing the opening. This allows some of the oil drawn out by the circulation pump 121 to flow back into the first liquid storage structure 110 through the bypass regulating pipe 170, thereby improving the fluidity of the oil in the first liquid storage structure 110 and preventing some of the oil in the first liquid storage structure 110 from condensing and adhering to the inner wall of the first liquid storage structure 110 due to long-term static state. Preferably, the bypass regulating pipe 170 is located downstream of the one-way valve.

[0100] In this embodiment of the present invention, an overflow pipe 180 branches off from the circulation pipe 122. The liquid outlet of the overflow pipe 180 is connected to the interior of the first liquid storage structure 110. An overflow valve is provided on the overflow pipe 180, and a second pressure gauge 160 is provided on the overflow valve. The overflow valve switches on and off according to the pressure value monitored by the second pressure gauge 160. Preferably, when the pressure value monitored by the second pressure gauge 160 is less than a preset overflow value, the overflow valve is controlled to close; when the pressure value monitored by the second pressure gauge 160 is greater than or equal to the overflow value, the overflow valve is controlled to open. The overflow value is less than the allowable pressure value of the heat exchanger, so that the overflow valve is used as a safety valve to prevent overpressure and protect the equipment.

[0101] In this embodiment of the present invention, the overflow pipe 180 is located downstream of the bypass regulating pipe 170, and the bypass regulating valve adjusts its opening according to the pressure value monitored by the second pressure gauge 160. Preferably, under normal conditions, the pressure value monitored by the second pressure gauge should be lower than the overflow value, and the opening of the bypass regulating valve increases as the pressure value monitored by the second pressure gauge 160 increases. When the pressure in the circulation pipe 122 is too high, the bypass regulating valve increases its opening to increase the flow rate in the bypass regulating pipe 170, thereby regulating the pressure in the circulation pipe 122.

[0102] In this embodiment of the invention, the control device 3 is provided with a control panel 310. The control panel 310 is provided with a first display component 311, which switches the display state to indicate the operating status of the cooling device 1; and a second display component 313, which switches the display state to indicate the operating status of the oil mist lubrication device 2. The first display component 311 and the second display component 313 are located in independent control areas, so that technicians can simultaneously observe the display components of the oil mist lubrication device 2 and the cooling device 1 through a single control panel 310, which facilitates the technicians to evaluate the working status of the two devices. Furthermore, by dividing the display components into zones, technicians can easily distinguish the devices corresponding to each display component, avoid confusion, and prevent misjudgment of the working status of the lubrication and cooling equipment, which could lead to incorrect operation.

[0103] In embodiments of this utility model, multiple first display components 311 and second display components 313 are respectively provided, with each first display component 311 centrally located within a first control area and each second display component 313 centrally located within a second control area.

[0104] In one embodiment of this utility model, the first region and the second region are arranged in a left-right direction.

[0105] In another embodiment of this utility model, the first region and the second region are arranged in a vertical direction; preferably, the second region is located above the first region; so that the second region is set close to the first pressure gauge 240, which facilitates the technician to make a comprehensive judgment on the operation of the oil mist lubrication device 2 based on the second display component 313 and the first pressure gauge 240; more preferably, the position of the second pressure gauge 160 is lower than or level with the first region.

[0106] In this embodiment of the present invention, the control panel 310 is further provided with a first control component 312 for adjusting the operating state of the cooling device 1; a second control component 314 for adjusting the operating state of the oil mist lubrication device 2; the first control component 312 and the first display component 311 are both located in the first area, and the second control component 314 and the second display component 313 are both located in the second area.

[0107] By setting up the above-mentioned control components and their corresponding display components in the same control area, technicians can intuitively see the operation and loading of the corresponding device and make immediate adjustments through the adjacent control components. This "what you see is what you get" operation mode greatly improves the ease of operation and accuracy of the equipment, reduces the risk of misoperation caused by confusing control components to a certain extent, and improves the stability and safety of equipment operation.

[0108] In the embodiments of this utility model, the first display component 311 and the first control component 312 are arranged in at least one row in the first area; the second display component 313 and the second control component 314 are arranged in at least one row in the second area; and each component in the first area and the second area is arranged centered along the same virtual vertical center line.

[0109] In one embodiment of this utility model, the cooling device 1 cools the shaft body by water cooling.

[0110] In another preferred embodiment of the present invention, the cooling device 1 cools the shaft body by oil cooling, and the first liquid storage structure 110 of the cooling device 1 stores and releases oil; the oil mist lubrication device 2 includes a second liquid storage structure 210 for storing oil; the first liquid storage structure 110 and the second liquid storage structure 210 are connected by a switchable conveying component 5.

[0111] With the above configuration, compared to water cooling, oil cooling eliminates the need for operations such as draining the cooling medium from the circulation component 120 and drying it with compressed air when the cooling device 1 is shut down. It also eliminates concerns about the cooling medium corroding the pipes, simplifying maintenance. Furthermore, the pipes can be made of low-cost materials other than stainless steel, reducing equipment costs. Additionally, oil has a wider operating temperature range, allowing the use of oils with lower freezing points to cope with low-temperature environments, resulting in more stable operation and ensuring the efficient and stable operation of the chemical fiber spinning system. More importantly, the first liquid storage structure 110 and the second liquid storage structure 210 are connected via the conveying component 5, enabling flexible allocation and sharing of cooling and lubricating oils. This improves resource utilization; when one is low on oil while the other has a sufficient supply, the oil can be allocated to meet normal operating requirements, providing technicians with more time for oil replenishment and preventing errors due to time constraints.

[0112] In one embodiment of this utility model, the conveying component 5 includes: a connecting pipe, one end of which is connected to the bottom of the second liquid storage structure 210, and the other end extending into the interior of the first liquid storage structure 110; a connecting valve for controlling the opening and closing of the connecting pipe; and a conveying pump, disposed within the first liquid storage structure 110 and connected to the connecting pipe, for conveying oil from the first liquid storage structure 110 to the second liquid storage structure 210; when the oil level in the first liquid storage structure 110 is low, the connecting valve is opened, allowing the oil in the second liquid storage structure 210 to flow into the first liquid storage structure 110 under gravity; when the oil level in the second liquid storage structure 210 is low, the connecting valve and the conveying pump are opened, allowing the oil in the first liquid storage structure 110 to flow into the second liquid storage structure 210.

[0113] In another preferred embodiment of the present invention, the first liquid storage structure 110 is connected to a circulation component 120, and a three-way structure is connected in series on the circulation pipe 122 of the circulation component 120. The conveying component 5 is connected to the outlet end of the three-way structure. The oil in the first liquid storage structure 110 enters the second liquid storage structure 210 in sequence through the circulation component 120, the three-way structure and the conveying component 5.

[0114] By utilizing the existing circulation component 120, the circulation component 120 draws oil from the first liquid storage structure 110 into the circulation pipe 122, and then connects it to the conveying component 5 through the three-way structure. This satisfies the conveying function while reducing one pump and related electrical control components, thereby lowering purchase and maintenance costs.

[0115] In this embodiment of the present invention, the conveying component 5 includes a conveying pipe 510 and a conveying valve 520 disposed on the conveying pipe 510 for controlling the opening and closing of the conveying pipe 510. During the operation of the cooling device 1, the circulating pump 121 is always in operation. When the oil level in the second liquid storage structure 210 is low, the conveying valve 520 only needs to be opened to divert the oil in the circulating pipe 122 to the conveying pipe 510 and enter the second liquid storage structure 210. Thus, the first liquid storage structure 110 can be made to replenish the second liquid storage structure 210 above it through simple control logic. The structure is simple and the reliability is high.

[0116] In this embodiment of the invention, a one-way valve is provided on the circulation pipe 122, which is located upstream of the conveying assembly 5.

[0117] In this embodiment of the invention, the top of the control device 3 is equipped with an audible and visual alarm 320, which has multiple alarm modes; it is used to alert technicians to the working status of the lubrication and cooling equipment.

[0118] In the embodiments of this utility model, a chemical fiber spinning system is also introduced, which uses a lubrication and cooling device for a chemical fiber spinning system as described above.

[0119] In the embodiments of this utility model, the roller body of the chemical fiber spinning system includes a cold roller, and the cold roller has an integrated cooling channel for the cooling medium to pass through. The cooling device 1 is connected to the cooling channel; specifically, the cooling channel is connected in series on the circulation pipe 122 of the cooling device 1.

[0120] In this embodiment of the invention, the rollers of the chemical fiber spinning system rotate under the drive of a matching motor. The motor is equipped with bearings, and at least a portion of the bearings have cooling channels on their jackets for the passage of cooling medium. The cooling device 1 is connected to the cooling channels. Specifically, the cooling channels are connected in series to the circulation pipe 122 of the cooling device 1.

[0121] In the embodiments of this utility model, the roller body of the chemical fiber spinning system includes a hot roller, and each bearing connected to the hot roller is provided with a cooling medium through a cooling channel. The cooling device 1 is connected to the cooling channel. By providing a cooling channel connected to the cooling device on each bearing corresponding to the hot roller, the bearing operating temperature on the hot roller is prevented from being too high, thus preventing accelerated wear.

[0122] In this embodiment of the invention, the rollers of the chemical fiber spinning system rotate under the drive of a matching motor. The motor is equipped with a bearing, and the outlet end of the oil mist channel of the oil mist lubrication device 2 sprays oil mist onto the bearing to form an oil film between the inner and outer rings of the bearing, thereby reducing the friction between the inner and outer rings.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
