Description

Technical Field

[0001] This utility model relates to the field of wire drawing technology in enameled wire production, and in particular to a wire drawing fluid circulation tank. Background Technology

[0002] The production process of enameled wire consists of drawing, cleaning, annealing and softening, multiple coatings, and baking, with the final step of winding the wire into a spool. In the drawing process, the coarse metal wire is formed into a fine wire of a set specification, and the drawing fluid is used to reduce friction, quickly dissipate heat, and clean the wire. The amount of drawing fluid used is large, especially in large-scale production where multiple drawing machines work simultaneously, requiring rapid treatment of the drawing fluid to meet the needs of recycling.

[0003] Existing technologies include equipment for centralized treatment of wire drawing fluid. For example, CN106734294A discloses a centralized circulating cooling system for wire drawing machine oil, which removes impurities from the recovered wire drawing fluid after sedimentation in an air flotation cooling tank before reuse. While this system can handle large quantities of wire drawing fluid, the metal particles in the fluid are difficult to settle quickly in the sedimentation tank, especially since the sedimentation tank is directly connected to the return pipe, causing turbulence and resulting in insufficient cleanliness of the wire drawing fluid. Another example is a purification device for ultrafine filament lubricant disclosed in CN116726602A, which uses a paper tape filter between two sedimentation processes. However, the two sedimentation processes are time-consuming, and the volume of wire drawing fluid used is large. Utility Model Content

[0004] The purpose of this invention is to provide a wire drawing fluid circulation tank that can quickly process wire drawing fluid and produce a high degree of cleanliness after processing.

[0005] To achieve this objective, the present invention adopts the following technical solution: A drawing fluid circulation tank includes a collection tank, a sedimentation tank, and a storage tank. A guide channel is connected to the bottom of the collection tank, and an annular filter belt is installed at the bottom of the collection tank. The guide channel passes through the annular filter belt and is used to guide the drawing fluid from the annular filter belt into the sedimentation tank. A slag collection container is installed on the outside of the collection tank, located below one end of the annular filter belt. The sedimentation tank is connected to the storage tank via an overflow outlet; the bottoms of the sedimentation tank and the storage tank are respectively connected to the collection tank via pipes.

[0008] Furthermore, a cleaning tank is provided below the liquid collection tank, and the lower part of the annular filter belt is immersed in the cleaning solution in the cleaning tank. The guide channel is connected to a liquid distribution pipe, the end of which extends into the cleaning tank, and the bottom of the cleaning tank is connected to the collection tank via a pipeline.

[0009] Furthermore, guide rollers are respectively provided in the lower and upper parts of the cleaning tank, and the lower part of the annular filter belt is guided by the guide rollers.

[0010] Furthermore, the liquid collection tank has a return pipe above it, the outlet end of the return pipe extends into the liquid collection tank, and the outlet end of the return pipe is connected to a dispersing head, with liquid outlets opened on the side and bottom of the dispersing head respectively.

[0012] Furthermore, the bottom wall of the sedimentation tank slopes downwards along the direction from the storage tank to the collection tank.

[0013] Furthermore, the liquid storage tank is provided with a vertical upper partition and a lower partition, which are arranged vertically in an alternating manner, dividing the liquid storage tank into an outlet section and a storage section.

[0014] The technical solution provided by this utility model can include the following beneficial effects: In this design, the annular filter belt is positioned at the bottom of the collection tank, providing a large filtration area and increasing filtration speed. The slag collection container collects the filter residue carried by the annular filter belt, ensuring timely cleaning and further improving filtration efficiency.

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] The following is combined with Figures 1 to 4 This invention describes a drawing fluid circulation tank according to an embodiment of the present invention, comprising a collection tank 1, a sedimentation tank 2, and a storage tank 3. A guide channel 11 is connected to the bottom of the collection tank 1, and an annular filter belt 4 is provided at the bottom of the collection tank 1. The guide channel 11 passes through the annular filter belt 4 and is used to guide the drawing fluid in the annular filter belt 4 into the sedimentation tank 2. A slag collection container 5 is provided on the outside of the collection tank 1, and the slag collection container 5 is located below one end of the annular filter belt 4. The sedimentation tank 2 is connected to the storage tank 3 through the overflow port 21; the bottoms of the sedimentation tank 2 and the storage tank 3 are respectively connected to the collection tank 1 through pipes.

[0019] In this design, the annular filter belt 4 is positioned at the bottom of the collection tank 1, providing a large filtration area and improving filtration speed. The slag collection container 5 collects the filter residue carried by the annular filter belt 4, ensuring timely cleaning and further enhancing filtration efficiency. The sedimentation tank 2 further settles metal particles in the drawing solution, while the storage tank 3 stores the cleaned drawing solution to meet drawing requirements. Since the sedimentation tank 2 and storage tank 3 are connected to the collection tank 1, the turbid liquid at the bottom of both tanks can be transported to the collection tank 1 for filtration, facilitating slag discharge from both tanks.

[0020] Specifically, the inner wall of the liquid collection tank 1 is provided with a sealing strip 12, and the upper edge of the annular filter belt 4 is slidably engaged with the sealing strip 12; The liquid collection tank 1 is provided with two squeeze rollers 13 at its two ends, and the two squeeze rollers 13 respectively press the annular filter belt 4 and the side wall of the liquid collection tank 1.

[0021] The edge of the annular filter belt 4 achieves a relative seal with the inner wall of the collection tank 1 through a sliding engagement with the sealing strip 12. The extrusion roller 13, with a polyurethane surface layer, is used to seal both ends of the collection tank 1, achieving a leak-proof effect. It is understood that the annular filter belt 4 achieves filtration by gravity. Since the amount of drawing liquid remaining in the collection tank 1 is small, the pressure on the sealing part between the annular filter belt 4 and the collection tank 1 is low, and a sealing effect can be achieved through the extrusion roller 13 and the sealing strip 12. In this embodiment of the invention, the annular filter belt 4 is a paper belt, polyester filter belt, or polypropylene filter belt, and the edge of the filter belt is provided with reinforcing ribs to facilitate a sliding engagement with the sealing strip 12. Specifically, the sealing strip 12 is a rubber sealing strip 12.

[0022] Preferably, the annular filter belt 4 is sleeved on the drive roller shaft 41 and the driven roller shaft 42, and a support roller shaft 43 is also provided between the drive roller shaft 41 and the driven roller shaft 42; The driven roller shaft 42 and the support roller shaft 43 are respectively positioned opposite the extrusion roller 13, and the drive roller shaft 41 corresponds to the slag removal mechanism 51 on the slag collection container 5.

[0023] The drive shaft is connected to the electric motor, and the drive roller shaft 41 can drive the annular filter belt 4 to move. As the annular filter belt 4 moves, the support roller shaft 43 and the extrusion roller 13 cooperate to squeeze out the drawing liquid carried on the annular filter belt 4, while carrying the filter residue out of the collection tank 1. Then, the filter residue is scraped off or shaken off by the slag removal mechanism 51 into the slag collection container 5, achieving the cleaning effect of the annular filter belt 4. Preferably, the surface of the extrusion roller 13 is smooth to avoid the adhesion of a large amount of filter residue.

[0024] Furthermore, a cleaning tank 14 is provided below the collection tank 1, and the lower part of the annular filter belt 4 is immersed in the cleaning liquid in the cleaning tank 14; the guide channel 11 is connected to a liquid distribution pipe 15, the end of the liquid distribution pipe 15 extends into the cleaning tank 14, and the bottom of the cleaning tank 14 is connected to the collection tank 1 through a pipeline.

[0025] When the filtered drawing liquid flows from the guide channel 11 to the sedimentation tank, part of the drawing liquid flows from the separator 15 into the cleaning tank 14. When the filter belt passes through the cleaning tank 14, it is cleaned by the drawing liquid in the tank, making the filter belt cleaner and thus further improving the filtration effect. The drawing liquid in the cleaning tank 14 is returned to the collection tank 1 through pipelines, realizing the circulation of the drawing liquid in the cleaning tank 14.

[0026] Specifically, guide rollers 16 are respectively provided in the lower and upper parts of the cleaning tank 14, and the lower part of the annular filter belt 4 is guided by the guide rollers 16. The guide rollers 16 are used to guide the annular filter belt 4 into the cleaning solution.

[0027] Preferably, the collection tank 1 has a return pipe 6 above it, the outlet end of which extends into the collection tank 1, and the outlet end of the return pipe 6 is connected to a dispersing head 61. The dispersing head 61 has outlets on its side and bottom. The return pipe 6 collects waste drawing liquid from multiple drawing machines and transports it to the collection tank 1. The dispersing head 61 at the end of the return pipe 6 disperses the waste liquid down onto the filter belt, improving the filtration speed.

[0028] In one embodiment of this utility model, the liquid collection tank 1 and the liquid storage tank 3 are respectively located on both sides of the sedimentation tank 2; the sedimentation tank 2 is provided with an inlet baffle 22 and a plurality of settling baffles 23, both sides of the inlet baffle 22 and the settling baffles 23 are connected to the inner wall of the sedimentation tank 2, the inlet baffle 22 is close to the guide channel 11, and the plurality of settling baffles 23 are arranged vertically side by side in the sedimentation tank 2; The top of the inlet baffle 22 is higher than the liquid surface in the sedimentation tank 2, and the top of the settling baffle 23 is lower than the liquid surface in the sedimentation tank 2. There are gaps between the bottom ends of both the inlet baffle 22 and the settling baffle and the bottom wall of the sedimentation tank 2. The arrangement of multiple settling baffles in the sedimentation tank 2 can block particles in the drawing liquid, improve sedimentation efficiency, and facilitate the rapid processing of large quantities of drawing liquid.

[0029] Preferably, the bottom wall of the sedimentation tank 2 slopes downwards along the direction from the storage tank 3 to the collection tank 1, so as to facilitate the transport of metal particles at the bottom of the sedimentation tank 2 to the collection tank 1. More preferably, the storage tank 3 is provided with a vertical upper baffle 31 and a lower baffle 32, which are vertically staggered, dividing the storage tank 3 into an outlet section 33 and a storage section 34. The upper baffle 31 and lower baffle 32 can isolate the bottom metal particles from the upper foam or floating impurities, further improving the cleanliness of the drawing fluid in the outlet section 33. Enamelled wire is commonly used for coil winding. The core wire dimensional accuracy and surface smoothness of the enamelled wire have a significant impact on the coil resistance. The purity of the drawing fluid used in the core wire drawing process of enamelled wire has a significant impact on the surface quality and dimensional accuracy of the core wire. The wire drawing fluid circulation tank of this invention thoroughly cleans the wire drawing fluid, improving the cleanliness of the supplied wire drawing fluid and making it suitable for drawing and forming enameled wire cores.
