Description

Technical Field

[0001] This utility model relates to the field of welding wire production and processing technology, and in particular to a high-temperature degreasing water filtration system for a high-speed welding wire production line. Background Technology

[0002] Traditional welding wire production lines operate at approximately 15 meters per second, while high-speed welding wire production lines operate at approximately 28 meters per second (because high-speed production lines have extremely high requirements for degreasing; inadequate degreasing and cleaning can easily lead to poor copper plating and weak copper film adhesion, affecting the quality of the welding wire). High-temperature degreasing equipment uses high temperatures and scouring pads to wash away the drawing powder and grease from the welding wire. During high-speed operation of the production line, grease accumulates in the high-temperature degreasing tank, continuously producing grease. Workers frequently use strainers to filter out the grease to ensure the water quality in the degreasing tank and avoid affecting the welding wire quality. This process significantly increases the workload for employees, and they may easily forget to remove the grease when busy, which can easily lead to welding wire quality accidents.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] A preferred embodiment of this utility model proposes a high-temperature degreasing water filtration system for a high-speed welding wire production line. This filtration system is connected to the high-speed welding wire production line and is connected to the degreasing tank 1 through a pipeline to circulate and filter the wastewater in the degreasing tank 1.

[0020] For details, see Figure 1 The filtration system mainly includes components such as a base frame 6, a support frame 8, a primary filter box 2, a high-pressure water pump 3, and a filter tank 4. A fixing plate 7 is welded to the bottom of the base frame 6, and the high-pressure water pump 3 is mounted on the fixing plate 7. The support frame 8 is fixedly mounted on the base frame 6, the primary filter box 2 is fixedly mounted on the support frame 8, and the filter tank 4 sits on the base frame 6, located on one side of the primary filter box.

[0021] The high-pressure water pump 3 has an inlet end and an outlet end. The inlet end of the high-pressure water pump 3 is connected to the outlet of the pre-grease tank through a water pipe, and the outlet end of the high-pressure water pump 3 is connected to the inlet of the pre-filter box 2 through a water pipe.

[0022] like Figures 2-3 As shown, the primary filter box 2 mainly consists of a box body 21, a box cover 22, a rotary handle 23, several filter press plates 24, and several filter elements 25. The box body 21 is rectangular, with an open top surface. The box cover 22 is mounted on the top surface of the box body 21 and hinged to one side of the box body 21. A sealing structure is provided between the box cover 22 and the box body 21 to ensure a tight seal when the box cover 22 is closed, preventing water leakage.

[0023] See Figure 4 A limiting groove 210 is formed inside the housing 21. The width of the limiting groove 210 is adapted to the width of the filter press plate 24 and is used to limit the filter press plate 24. Several filter press plates 24 and several filter elements 25 are arranged at intervals and placed vertically in the limiting groove 210, and are tightly attached to each other.

[0024] like Figure 5 As shown, grooves are provided on both sides of the filter press plate 24, and several small protrusions 242 are formed in the grooves. At the same time, there are two round holes 240 on the filter press plate 24. Each round hole 240 has a hole 241 on its inner wall that is connected to the grooves on both sides of the filter press plate 24, so that the wastewater in the box 21 can enter the hole 241 through the round hole 240 and then flow into the grooves on both sides of the filter press plate 24.

[0025] The handle 23 has a screw, which is threadedly sealed to one end of the housing 21 along its length. By rotating the handle 23, the screw presses against the stacked filter plates 24 and filter elements 25, compressing them tightly. Adjacent filter plates 24 are tightly fitted together, and the filter elements 25 are sandwiched between adjacent filter plates 24. A gap is formed between the filter elements 25 and the grooves on the sides of the filter plates 24, while small protrusions 242 within the grooves support the filter elements 25, ensuring a sufficiently large gap between them.

[0026] The filter element 25 can be made of various materials such as non-woven fabric and glass fiber. In this embodiment, the filter element 25 is preferably made of non-woven fabric, which has a certain degree of softness and can filter large particulate impurities better.

[0027] The tank 21 has an inlet at the bottom and an outlet on one side. The high-pressure water pump 3 is connected to the inlet via a water pipe, and the filter tank 4 is connected to the outlet via a water pipe.

[0028] High-pressure water pump 3 pumps wastewater from degreasing tank 1 into primary filter box 2. The wastewater then enters two round holes 240 on several stacked filter plates 24, and then passes through holes 241 into the gap between filter plates 24 and filter elements 25. Through the interception, adsorption, and inertial collision of the filter material, large metal particles, suspended solids, and other impurities in the wastewater are captured. Ultimately, the impurities agglomerate to form filter residue, which remains in the gap between filter plates 24 and filter elements 25. Primary filter box 2 performs preliminary filtration of the wastewater.

[0029] like Figure 7 As shown, the filter tank 4 mainly consists of a tank body 41, a tank cover 42, a filter screen 43, a cleaning mechanism 5, and other components. The tank body 41 is cylindrical and hollow inside. The tank cover 42 is installed on the top of the tank body 41 and is sealed to the tank body 41. The tank cover 42 can be opened.

[0030] The filter screen 43 is cylindrical and is installed inside the tank 41, forming a sandwich between it and the inner wall of the tank 41. The top and bottom of the sandwich are also surrounded by the filter screen 43. In this way, wastewater can only pass through the filter screen 43 into the sandwich from the central area surrounded by the filter screen 43, and the wastewater will be filtered once by the filter screen 43.

[0031] An inlet pipe 411 and an outlet pipe 412 are installed on the tank body 41. The outlet pipe 412 is connected to the interlayer between the tank body 41 and the filter screen 43. After passing through the tank body 41 and the filter screen 43, the inlet pipe 411 is connected to the cavity in the central area of ​​the filter screen 43. This cavity is connected to the slag discharge port 413 at the bottom of the tank body 41.

[0032] After being initially filtered by the primary filter box 2, the wastewater enters the cavity in the central area of ​​the filter screen 43 through the inlet pipe 411. The wastewater passes through the filter screen 43 and enters the interlayer between the tank body 41 and the filter screen 43. The wastewater is further filtered by the filter screen 43. Finally, the filtered water comes out from the outlet pipe 412 and flows back into the degreasing tank 1.

[0033] like Figure 6 As shown, the cleaning mechanism 5 is located in the cavity in the middle of the filter screen 43. This cleaning mechanism 5 mainly consists of a motor 51, a rotating shaft 52, cleaning brushes 54, and scraper blades 53. The motor 51 is mounted on the top of the tank lid 42. The rotating shaft 52 is vertically oriented, with its upper end passing through the tank lid 42 and connected to the output shaft of the motor 51. The lower end of the rotating shaft 52 is rotatably connected to the bottom of the tank body 41. The rotating shaft 52 and the tank body 41 are detachably connected. Multiple scraper blades 53 and cleaning brushes 54 are provided, spaced apart along the circumference of the rotating shaft 52 and arranged along its axial direction, ensuring that the scraper blades 53 and cleaning brushes 54 can clean the entire surface of the filter screen 43 once the rotating shaft 52 rotates one revolution.

[0034] Both the scraper 53 and the cleaning brush 54 are close to the surface of the filter screen 43. The motor 51 drives the rotating shaft 52 to rotate, thereby moving the scraper 53 and the cleaning brush 54 in a circumferential direction. The scraper 53 scrapes off the sludge from the surface of the filter screen 43, while the cleaning brush 54 brushes the surface of the filter screen 43 again. This can thoroughly clean the surface of the filter screen 43 and prevent sludge from clogging the filter holes.

[0035] like Figure 7 As shown, a sludge discharge port 413 is provided at the bottom of the tank 41, through which the removed sludge can be discharged. An electric valve (not shown in the figure) is installed at the sludge discharge port 413. A pressure gauge (not shown in the figure) is also installed on the tank 41 of the filter tank 4, which can detect changes in water pressure inside the tank 41. During periodic water changes, the electric valve is opened to discharge the wastewater and sludge from the filter tank 4.

[0036] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
