Description

Technical Field

[0001] The present invention belongs to the technical field of solid-liquid separation, and more specifically refers to a solid-liquid separation device for treating alkaline cleaning waste liquid of aluminum profile extrusion dies. Background Art

[0002] During the production and processing of aluminum profiles, after the die has been used for a long time, a layer of aluminum will solidify in its cavity. At this time, it is necessary to use sodium hydroxide solution to corrode and clean the die. This process is called die alkaline cleaning. After alkaline cleaning, the sodium hydroxide solution will contain complex components such as sodium aluminate, oxides of alloy components, complexes, and hydroxides. This liquid is called waste alkali liquid.

[0003] In the alkaline cleaning process of aluminum profile extrusion dies, first, the die needs to be completely immersed in the alkaline cleaning solution with a certain concentration. As the alkaline cleaning process progresses, the concentration of the alkaline cleaning solution will change due to factors such as reaction with the die surface, dissolution of impurities, and evaporation of the liquid. In order to maintain the effective concentration of the alkaline cleaning solution and ensure the cleaning effect, the system will perform two operations simultaneously: on the one hand, continuously inject new alkaline cleaning solution into the alkaline cleaning solution to supplement the consumed alkali and maintain a certain liquid volume; on the other hand, also discharge part of the used waste liquid with a reduced concentration or more impurities to maintain the cleanliness and effectiveness of the liquid in the alkaline cleaning tank; However, a large number of tiny particles shed from the die surface, precipitates generated by the reaction, and suspended solids originally present in the alkaline cleaning solution float on the liquid surface of the alkaline cleaning solution. Since these solid impurities form a barrier on the liquid surface, they are not easily effectively pumped out during the liquid discharge process. This not only affects the cleanliness and recycling efficiency of the alkaline cleaning solution but also may cause trouble to subsequent waste liquid treatment steps. For this reason, we propose a solid-liquid separation device for treating alkaline cleaning waste liquid of aluminum profile extrusion dies. Summary of the Invention

[0004] In view of the above situation, to overcome the defects of the prior art, the present invention provides a solid-liquid separation device for treating alkaline cleaning waste liquid of aluminum profile extrusion dies, which at least partially solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a solid-liquid separation device for treating alkaline cleaning waste liquid of aluminum profile extrusion dies, including: a solid-liquid separation machine box body, a vertical feeding member is arranged in the solid-liquid separation machine box body, a die hanging member for hanging the die is arranged on the vertical feeding member, a die to be cleaned is hung on the die hanging member, and the solid-liquid separation machine box body is also filled with alkaline cleaning solution, and a solid residue filtering mechanism is arranged in the alkaline cleaning solution of the solid-liquid separation machine box body; The solid residue filtering mechanism includes a filtering chamber fixedly connected to the inner wall of the solid-liquid separation machine box body, a propeller is rotatably arranged inside the filtering chamber, and a wave generating mechanism is arranged on one side of the filtering chamber close to the vertical feeding member; The wave-making mechanism includes a fixing plate rotatably connected to the filtration chamber.

A pulling plate rope is fixedly arranged on the lower wall of the water deflecting plate. One end of the pulling plate rope away from the water deflecting plate is provided with a stress head penetrating through the filtration chamber. A pressing block for applying pressure to the stress head is arranged on the side wall of the propeller. When the propeller rotates to drive the pressing block to slide down and pull the pulling plate rope, the water deflecting plate reciprocates to fluctuate the alkaline cleaning solution, forming an artificial wave that impacts on the mold to be washed.

[0006] Furthermore, both ends of the propeller penetrate through the left and right side wall plates of the solid-liquid separator box body respectively. A driving motor is arranged at one end of the propeller, and a slag collection chamber fixedly connected to the solid-liquid separator box body is arranged at the end of the propeller away from the driving motor.

[0007] Furthermore, a filter net bottom for filtering the residues in the alkaline cleaning solution is fixedly arranged below the filtration chamber. A water suction pump is fixedly arranged on the side wall of the filtration chamber. The water inlet end of the water suction pump is fixedly connected with a number of water suction pipes, and the water inlets of the number of water suction pipes are distributed at the bottom of the alkaline cleaning solution in the solid-liquid separator box body. The number of water suction pipes is interconnected with the filtration chamber through the water suction pump.

[0008] Furthermore, a closing plate is arranged inside the water inlet through a torsion spring. A liquid receiving box I fixedly connected to the water deflecting plate is arranged below the water inlet. The liquid outlet of the liquid receiving box I is fixedly provided with a water outlet penetrating through the filtration chamber. The height dimension of the water outlet is smaller than the height dimension of the liquid receiving box I. A filter net is fixedly arranged on the bottom plate of the liquid receiving box I.

[0009] Furthermore, the wave-making mechanism also includes a water supply box fixedly connected to the outer wall of the filtration chamber. A liquid suction bladder is arranged inside the water supply box. A lower pressing plate slidably connected to the filtration chamber is fixedly arranged at the top of the liquid suction bladder. The lower pressing plate is fixedly connected to the stress head, and a spring column penetrates through the stress head.

[0010] Furthermore, a liquid inlet pipe is fixedly connected to the top of the liquid suction bladder. A liquid receiving box II is arranged at one end of the liquid inlet pipe away from the water supply box. The liquid receiving box II is fixedly connected to the bottom plate of the liquid receiving box I. The liquid receiving box II is interconnected with the liquid suction bladder through the liquid inlet pipe. When the alkaline cleaning solution filtered by the filter net flows into the liquid receiving box II, it is injected into the liquid suction bladder.

[0011] Furthermore, a blocking cylinder is arranged at the water outlet end of the liquid suction bladder. A limiting plate strip is fixedly arranged inside the blocking cylinder. Liquid cut-off plates are rotatably arranged on both sides of the limiting plate strip. Elastic bands fixedly connected to the limiting plate strip are arranged on both liquid cut-off plates.

[0012] Further, an extension hose is fixedly arranged on one side of the water deflecting plate close to the vertical feeding member. An impact ball is fixedly arranged at one end of the extension hose close to the vertical feeding member. Several extension hoses and several impact balls form a group, and the positions of several groups of extension hoses are staggered with several water inlets.

[0013] Further, a counterweight is fixedly arranged in the lower half of the impact ball, and a floating chamber is arranged in the upper half of the impact ball. When the extension hose is in a straightened state, the position of the impact ball is aligned with the mold to be washed.

[0014] Further, a liquid supply pipe 1 and a liquid supply pipe 2 are arranged inside the extension hose. Several liquid spraying holes are formed in the outer wall of the impact ball, and several liquid spraying holes are all communicated with the liquid supply pipe 1. One ends of the liquid supply pipe 1 and the liquid supply pipe 2 far away from the impact ball are both communicated with the liquid outlet of the blocking cylinder.

[0015] The beneficial effects obtained by the present invention with the above structure are as follows: (1) The present invention proposes that when the water deflecting plate moves upward in the clockwise direction, a wavy surface will be formed on the liquid surface, so that the liquid surface repeatedly impacts the mold to be washed. The wavy motion can improve the mass transfer efficiency, make the contact between the alkaline cleaning solution and the surface of the mold to be washed more sufficient and uniform, and thus more effectively remove the dirt and oxide layer on the surface of the mold to be washed. This dynamic cleaning method can achieve the cleaning effect more quickly compared with static soaking. The wave impact can generate a certain scouring force, which helps to wash away the stubborn stains and attachments on the surface of the mold to be washed; (2) The present invention proposes that the fixed impurities floating on the liquid surface will be impacted and slapped on the water deflecting plate by the waves. The scouring action of the waves can enhance the cleaning effect of the alkaline cleaning solution on the surface of the mold to be washed. At the same time, this dynamic process can also more effectively wash the solid impurities floating on the liquid surface to the vicinity of the water inlet of the wave-making plate. The impurities collide with the wave-making plate under the push of the waves, increasing the chance of the impurities being captured, thereby improving the efficiency of removing impurities.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying 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 thus should not be construed as a limitation to the present invention.

[0021] Such as Figure 1As shown in the figure, a solid-liquid separation device for treating alkaline cleaning waste liquid of an aluminum profile extrusion die includes: a solid-liquid separator box body 11, a vertical feeding member 12 is arranged in the solid-liquid separator box body 11, a die hanging member 13 for hanging the die is arranged on the vertical feeding member 12, a die to be washed 14 is hung on the die hanging member 13, and alkaline cleaning liquid is also contained in the solid-liquid separator box body 11. A solid residue filtering mechanism 2 is arranged in the alkaline cleaning liquid of the solid-liquid separator box body 11; The solid residue filtering mechanism 2 includes a filtering chamber 21 fixedly connected to the inner wall of the solid-liquid separator box body 11. A propeller 23 is rotatably arranged inside the filtering chamber 21. A wave generating mechanism 3 is arranged on one side of the filtering chamber 21 close to the vertical feeding member 12; As Figure 1 - Figure 4 As shown in the figure, the wave generating mechanism 3 includes a fixing plate 34 rotatably connected to the filtering chamber 21. A water deflecting plate 31 is rotatably arranged on the fixing plate 34. A number of water inlets 32 are formed on the water deflecting plate 31 for loading fixed floating slag that floats out due to the reverse impact of the alkaline cleaning liquid waves; A pulling plate rope 301 is fixedly arranged on the lower wall of the water deflecting plate 31. One end of the pulling plate rope 301 away from the water deflecting plate 31 is provided with a stress head 38 penetrating through the filtering chamber 21. A pushing block 3002 for applying pressure to the stress head 38 is arranged on the side wall of the propeller 23. When the propeller 23 rotates to drive the pushing block 3002 to slide down and pull the pulling plate rope 301, the water deflecting plate 31 reciprocates to fluctuate the alkaline cleaning liquid, forming an artificial wave that impacts on the die to be washed 14.

[0022] Both ends of the propeller 23 penetrate through the left and right side wall plates of the solid-liquid separator box body 11 respectively. A driving motor 22 is arranged at one end of the propeller 23. A slag collection chamber 24 fixedly connected to the solid-liquid separator box body 11 is arranged at the end of the propeller 23 away from the driving motor 22.

[0023] A filter mesh bottom 25 for filtering residues in the alkaline cleaning liquid is fixedly arranged below the filtering chamber 21. A water suction pump is fixedly arranged on the side wall of the filtering chamber 21. The water inlet end of the water suction pump is fixedly connected with a number of water suction pipes 26. The inlets of the number of water suction pipes 26 are distributed at the bottom of the alkaline cleaning liquid in the solid-liquid separator box body 11. The number of water suction pipes 26 is communicated with the filtering chamber 21 through the water suction pump.

[0024] A closing plate 33 is arranged inside the water inlet 32 through a torsion spring. A first liquid receiving box 302 fixedly connected to the water deflecting plate 31 is arranged below the water inlet 32. A water outlet 35 penetrating through the filtering chamber 21 is fixedly arranged at the liquid outlet of the first liquid receiving box 302. The height dimension of the water outlet 35 is smaller than the height dimension of the first liquid receiving box 302. A filter mesh 303 is fixedly arranged on the bottom plate of the first liquid receiving box 302.

[0025] First, hang the mold 14 to be washed on the mold hanging member 13. Drive the mold hanging member 13 to move downward through the operation of the vertical loading member 12 until several molds 14 to be washed are completely immersed in the caustic cleaning solution. After long-term use, a layer of aluminum will solidify in the cavity of the mold 14 to be washed. At this time, it is necessary to use the caustic cleaning solution of sodium hydroxide solution to corrode and clean the mold. This process is called mold caustic cleaning. After washing, drive the mold hanging member 13 to move upward through the vertical loading member 12 to lift the mold 14 to be washed out of the caustic cleaning solution; After the caustic cleaning solution is used to clean the mold 14 to be washed multiple times, the caustic sodium hydroxide solution after caustic cleaning will contain complex components such as sodium aluminate, oxides of alloy components, complexes, and hydroxides. A large amount of impurities will float on the water surface and deposit at the bottom. Through the operation of the suction pump, the waste liquid is sucked into the filtration chamber 21 from multiple water suction pipes 26. The fixed impurities in the sucked waste liquid will be blocked in the filtration chamber 21 by the filter net bottom 25, thus playing a role in solid-liquid separation; A large amount of solid impurities drive the propeller 23 to rotate under the operation of the driving motor 22, so that the solid impurities are conveyed to the slag collection chamber 24 through the propeller 23 for subsequent treatment.

[0026] As Figure 5 - Figure 8 shown, the wave-making mechanism 3 further includes a water supply box 36 fixedly connected to the outer wall of the filtration chamber 21. A liquid suction bladder 305 is arranged inside the water supply box 36. A lower pressure plate 304 slidably connected to the filtration chamber 21 is fixedly arranged at the top of the liquid suction bladder 305. The lower pressure plate 304 is fixedly connected to the force receiving head 38, and a spring column 37 is penetrated inside the force receiving head 38.

[0027] A liquid inlet pipe 39 is fixedly connected to the top of the liquid suction bladder 305. A liquid receiving box two 3001 is arranged at one end of the liquid inlet pipe 39 away from the water supply box 36. The liquid receiving box two 3001 is fixedly connected to the bottom plate of the liquid receiving box one 302. The liquid receiving box two 3001 is communicated with the liquid suction bladder 305 through the liquid inlet pipe 39. When the caustic cleaning solution filtered by the filter net 303 flows into the liquid receiving box two 3001, it is injected into the liquid suction bladder 305.

[0028] A blocking cylinder 306 is arranged at the water outlet end of the liquid suction bladder 305. A limiting plate strip 307 is fixedly arranged inside the blocking cylinder 306. Liquid cut-off plates 308 are rotatably arranged on both sides of the limiting plate strip 307. Elastic bands 309 fixedly connected to the limiting plate strip 307 are arranged on both liquid cut-off plates 308.

[0029] The rotation of the propeller 23 drives the rotation of the pressing block 3002. The pressing block 3002 pushes the force-receiving head 38 to slide downward. When the force-receiving head 38 slides downward, it will pull the pull plate rope 301, causing the water deflecting plate 31 to rotate counterclockwise. As a result, the water deflecting plate 31 presses down on the liquid surface, causing the liquid surface to fluctuate far away. Then, when the pressing block 3002 disengages from the force-receiving head 38, the elastic force of the spring column 37 pushes the force-receiving head 38 to slide upward and reset. After that, the elastic piece 3003 fixed at the angle between the water deflecting plate 31 and the fixed plate 34 pushes the water deflecting plate 31 to rotate clockwise. When the water deflecting plate 31 rotates upward in the clockwise direction, a wave surface will be formed on the liquid surface, causing the liquid surface to repeatedly impact the mold to be washed 14. The wave-like movement can improve the mass transfer efficiency, making the contact between the alkaline cleaning solution and the surface of the mold to be washed 14 more sufficient and uniform. Thus, the dirt and oxide layer on the surface of the mold to be washed 14 can be removed more effectively. Compared with static immersion, this dynamic cleaning method can achieve the cleaning effect more quickly. The wave impact can generate a certain scouring force, which helps to wash away the stubborn stains and attachments on the surface of the mold to be washed 14; When the water deflecting plate 31 generates waves each time it rotates, the fixed impurities floating on the liquid surface will be impacted by the waves and slapped on the water deflecting plate 31. The scouring effect of the waves can enhance the cleaning effect of the alkaline cleaning solution on the surface of the mold to be washed 14. At the same time, this dynamic process can also more effectively wash the solid impurities floating on the liquid surface to the vicinity of the water inlet 32 of the wave-making plate. The impurities collide with the wave-making plate under the push of the waves, increasing the chance of the impurities being captured, thereby improving the efficiency of removing impurities.

[0030] On one side of the water deflecting plate 31 close to the vertical feeding member 12, an extension hose 41 is fixedly arranged. At one end of the extension hose 41 close to the vertical feeding member 12, an impact ball 42 is fixedly arranged. And several extension hoses 41 and several impact balls 42 form a group. The positions of several groups of extension hoses 41 are staggered with the positions of several water inlets 32.

[0031] A counterweight 45 is fixedly arranged in the lower half of the impact ball 42. An air chamber 47 is arranged in the upper half of the impact ball 42. When the extension hose 41 is in a straightened state, the position of the impact ball 42 is aligned with the mold to be washed 14.

[0032] A liquid supply pipe one 43 and a liquid supply pipe two 44 are arranged inside the extension hose 41. A plurality of liquid spraying holes 46 are formed in the outer wall of the impact ball 42. All the plurality of liquid spraying holes 46 are communicated with the liquid supply pipe one 43. One ends of the liquid supply pipe one 43 and the liquid supply pipe two 44 far away from the impact ball 42 are both communicated with the liquid outlet of the blocking cylinder 306.

[0033] The pushing block 3002 is used to push the force-receiving head 38 to slide downward, driving the lower pressing plate 304 to squeeze the liquid suction sac 305. Under pressure, the liquid cutoff plate 308 opens, allowing the liquid to flow from the cutoff cylinder 306 into the first liquid supply pipe 43 and the second liquid supply pipe 44. After the liquid enters the second liquid supply pipe 44, the extension hose 41 is straightened. Under the impact of the waves, the impact ball 42 hits the mold 14 to be washed, causing the mold 14 to be washed vibrate, which is beneficial to shake off the water droplets when the mold 14 to be washed emerges from the liquid surface; Part of the liquid is ejected from a plurality of liquid ejection holes 46 through the first liquid supply pipe 43, and can wash the mold 14 to be washed that has just emerged from the liquid surface; Each group of extension hoses 41 and a plurality of water inlets 32 are distributed alternately, which is beneficial to control the solid impurities floating on the liquid surface to be in a position aligned with the water inlets 32, facilitating the collection of solid impurities.
