Description

Technical Field

[0001] The present invention relates to the field of filtering equipment, in particular to a filtering device for preparing butyl ammonium nitrate. Background Art

[0002] Butyl ammonium black powder is an excellent collector for non-ferrous metal ores and plays an important role in the mineral processing process. In one preparation method of butyl ammonium black powder, phosphorus pentasulfide and butanol are required as raw materials. The production process of phosphorus pentasulfide mainly includes several steps such as raw material preparation - hot melt mixing - heating reaction - tableting. After roller rolling, phosphorus pentasulfide is in flake form.

[0003] In order to improve the mixing effect of phosphorus pentasulfide and butanol and enhance the preparation efficiency of butylammonium black medicine, it is necessary to process flaky phosphorus pentasulfide into powder and further purify it. In this case, the flaky phosphorus pentasulfide needs to be ground and crushed before being placed in an extraction device, and a protective solvent is added to the extraction device. The ground phosphorus pentasulfide is dissolved in the protective agent, and impurities in the phosphorus pentasulfide raw material are incompatible with the protective solvent. Finally, solid particles in the protective solvent are separated from the solution by filtration, and the protective solvent is recovered by evaporation or distillation to obtain pure phosphorus pentasulfide powder.

[0004] For related technology, see Chinese patent publication number CN214861322U, which discloses a small, multifunctional extractor capable of tank bottom discharge. The device comprises: a tank with a bottom-dischargeable filter screen and a heater; a bottom connected to a material pump via pipes and valves; a tank lid with an exhaust valve, an illuminated sight glass, and a pressure / vacuum gauge; a condenser connected to the tank lid via pipes; a cooler connected to the condenser; a dual-chamber oil-water separator connected to the cooler; and the end of the dual-chamber oil-water separator connected to the tank. A bracket supports the tank, and a distribution box is placed on the bracket to connect and control the electrical components. The extractor boasts high performance and reliable safety.

[0005] Regarding the above-mentioned related technologies, in the process of separating the protective solution from solid impurities, although vacuum suction can be applied to the protective solution in the tank through the material pump, so that the protective solution passes through the filter and is discharged outward under the action of the material pump, in the process of the filter filtering solid particles, the solid particles are also subjected to the thrust of the solution flow, causing the solid particles to adhere to the filter. When a large amount of protective solvent needs to be filtered and separated, the solid particles on the filter are likely to affect the filtration efficiency of the protective solvent, thereby reducing the filtration efficiency of the protective solution. Summary of the Invention

[0006] In order to reduce the impact of impurity solid particles in the solution on the solution filtration efficiency, the present application provides a filtering device for preparing butyl ammonium black medicine.

[0007] The present application provides a filtering device for preparing butyl ammonium black medicine, which adopts the following technical solution:

[0008] A filtering device for preparing butyl ammonium black medicine comprises an extraction cylinder, the upper end of the extraction cylinder is detachably connected to a cylinder cover, the cylinder cover is provided with a feeding part for adding raw materials, the lower end is connected to a discharge pipe, the discharge pipe is provided with a delivery pump for extracting solution, a placement cylinder is provided in the extraction cylinder, the lower end of the placement cylinder is opened with an opening, and a filter screen is provided along the opening, a support frame is provided in the placement cylinder, the support frame is located at the lower end of the placement cylinder, a plurality of sealing plates are evenly arranged in the horizontal direction in the support frame, the sealing plates are rotatably connected to the support frame along the vertical direction, when all the sealing plates are in a horizontal state, any two adjacent sealing plates abut against each other, a movable plate is provided at the lower end of the placement cylinder, and the extraction cylinder is provided with a filter screen for carrying The movable plate moves closer to or away from a pushing member of the placing cylinder, and a connecting member is provided between the movable plate and the sealing plate. When the movable plate moves, the sealing plate is driven to rotate by the connecting member, and the placing cylinder is provided with a discharge port along the circumference, and the discharge port is above the support frame. The placing cylinder is provided with a baffle, and the upper end of the baffle is hinged with the placing cylinder, and the placing cylinder is provided with an elastic member. The elastic member pushes the baffle to block the discharge port, and the lower end of the baffle is hinged with a push rod, and a cross bar is vertically fixed at one end of the push rod away from the baffle, and the movable plate is circumferentially fixed with a plurality of support blocks corresponding to the baffle, and the support block is provided with a limiting slot vertically, and the cross bar is inserted in the limiting slot and is slidably connected to the support block along the length direction of the limiting slot.

[0009] By adopting the above-mentioned technical solution, the cylinder cover is used to seal the extraction cylinder. The ground phosphorus pentasulfide raw material is fed into the storage cylinder through the feeding section. Initially, the pusher drives the movable plate to move, thereby sealing the open opening. The baffle, under the action of elastic member 1, blocks the discharge port. At this time, the storage cylinder is in a closed state. The solution and phosphorus pentasulfide mix in the storage cylinder. The solid impurities in the phosphorus pentasulfide are insoluble in the solution. After a period of stagnant state, the solid impurities settle to the lower end of the storage cylinder due to gravity. The support frame supports the sealing plates. When the movable plate contacts the storage cylinder, all sealing plates are tilted, and solid impurities enter the bottom of the storage cylinder through the gaps between adjacent sealing plates and come into contact with the filter screen. When the movable plate contacts the placement cylinder, the cross bar is located at the lower end of the limit slot. At this time, the movable plate is driven downward by the push member, and the cross bar moves relative to the support block along the limit slot. When the movable plate moves, the connecting member drives the sealing plate to rotate, so that the sealing plate rotates to a horizontal state. At this time, all the sealing plates cooperate to seal the solid impurities between the sealing plate and the filter screen. When the cross bar moves to the upper end of the limit slot and contacts the support block, the support block drives the push rod to move through the cross bar, so that the push rod drives the baffle to separate from the drain port, so that the solution flows through the drain port to the drain pipe. The delivery pump is used to improve the discharge efficiency of the solution, and at this time, the solution under the sealing plate passes through the filter screen and flows out from the gap between the movable plate and the placement cylinder, thereby completing the filtration of the solution, so that the solid impurities are separated from the solution. The solid impurities are concentrated under the sealing plate. Most of the solution does not need to be filtered when it is discharged, which is beneficial to improve the filtration efficiency of the solution and reduce the influence of impurity solid particles in the solution on the filtration efficiency of the solution.

[0010] Optionally, the sealing plate includes an intermediate plate, a torsion spring and two rotating rods, the two rotating rods are located in the same axis and are rotatably connected to the support frame, the connecting part is used to drive the rotating rod to rotate, the intermediate plate is located between the two rotating rods, and the side of the rotating rod close to the intermediate plate is connected to the polygonal rod by sliding along the axial direction, and an elastic part two is provided between the polygonal rod and the rotating rod, and the elastic part two is used to push the polygonal rod away from the rotating rod, and the intermediate plate is provided with a limiting hole adapted for the polygonal rod, the polygonal rod is inserted into the limiting hole and fits into the inner wall of the limiting hole, and a gripping block is vertically fixed on the side of the polygonal rod away from the rotating rod, and the intermediate plate is provided with an opening connected to the limiting hole along the length direction, the gripping block passes through the opening and is slidably connected to the intermediate plate along the length direction of the opening, the torsion spring is located between the rotating rod and the support frame, and is used to position the rotating rod. When the torsion spring is in a natural state, the intermediate plate is in an inclined state.

[0011] By adopting the above technical solution, the support frame supports the rotating rod. Initially, the polygonal rod is inserted into the limiting hole under the action of the second elastic member. When the rotating rod rotates, the polygonal rod and the limiting hole cooperate to drive the middle plate to rotate, realizing the flipping of the sealing plate. The torsion spring is used to position the rotating rod, and after the sealing plate flips, it drives the rotating rod and the middle plate to reset. When the filter needs to be replaced, after removing the cylinder cover, the gripping block is moved along the opening to remove the polygonal rod from the limiting hole. The middle plate and polygonal rod can be separated. After removing the middle plate from the support frame, it is convenient to replace the filter.

[0012] Optionally, the support frame is provided with a disassembly plate on both sides along the length direction of the sealing plate, the disassembly plate is slidably connected to the support frame along the length direction of the sealing plate, a cylindrical block is coaxially fixed to the polygonal rod, the cylindrical block passes through the disassembly plate and is rotatably connected to the disassembly plate, and an abutment plate is fixed to one end of the cylindrical block close to the rotating rod, and the abutment plate is in contact with the side of the disassembly plate facing away from the middle plate.

[0013] By adopting the above technical solution, when the polygonal rod is inserted into the limiting hole under the action of the second elastic member, the abutment plate contacts the disassembly plate. When the middle plate needs to be disassembled, the disassembly plate is pressed away from the middle plate, so that the disassembly plate drives all the polygonal rods on the same side of the support frame to move synchronously through the abutment plate and the cylindrical block, which is conducive to improving the work efficiency of disassembling and installing the middle plate.

[0014] Optionally, the connecting member includes a moving rod, a rotating plate and a connecting rod, the connecting rod is vertically fixed on one side of the rotating rod, the moving rod is vertically slidably connected to the lower end of the support frame, and the moving rod is passed through a placement tube and fixedly connected to the moving plate, the rotating plate is located between the moving plate and the connecting rod, and one end of the rotating plate is hinged to the connecting rod, and the other end is rotatably hinged to the connecting rod.

[0015] By adopting the above technical solution, when the movable plate moves, the movable rod drives the rotating plate to move, and when the rotating plate moves, the connecting rod drives the rotating rod to rotate, thereby realizing the flipping of the middle plate.

[0016] Optionally, an annular groove is provided at the lower end of the placement tube, the support frame is located in the annular groove and is vertically slidably connected to the placement tube, and an elastic member three is provided between the support frame and the placement tube, and the elastic member three applies a thrust to the support frame away from the movable plate, and the placement tube is provided with a positioning member for limiting the movement of the support frame.

[0017] By adopting the above technical solution, when the sealing plate needs to be rotated, the positioning part positions the support frame. When all the sealing plates are in a horizontal state and isolate the solid impurities, the movable plate continues to move downward. At this time, the sealing plate cannot continue to rotate, and the positioning part releases the positioning of the support frame. When the movable plate moves, it drives the support frame downward, causing the elastic part to deform. When the support frame moves, it drives the sealing plate close to the filter screen, thereby pushing the solution under the sealing plate to pass through the filter screen, thereby accelerating the filtration efficiency of the solution mixed with solid impurities.

[0018] Optionally, the positioning member includes a positioning rod, a pushing block and an elastic member four. A moving groove is opened in the horizontal direction at the lower end of the placement cylinder. The positioning rod passes through the moving groove and is slidably connected to the placement cylinder along the length direction of the moving groove. When the support frame is in the position, the support frame has an avoidance groove opened in the vertical direction. One end of the moving groove is located directly below the avoidance groove. The elastic member four is located between the positioning rod and the placement cylinder, applying a thrust to the positioning rod away from the avoidance groove. The moving plate has a through groove opened in the vertical direction. The lower end of the positioning rod passes through the through groove and extends to the lower end of the moving plate. The pushing block is fixedly connected to the lower end of the positioning rod, and a guide surface is provided on the side of the pushing block close to the moving plate. When the moving plate moves along the guide surface, the positioning rod is driven to move toward the avoidance groove.

[0019] By adopting the above technical solution, initially, the support frame is at the farthest end from the filter screen, the upper end of the positioning rod contacts the lower end of the support frame, thereby limiting the vertical movement of the support frame. The push block is located below the movable plate, and the movable plate contacts the guide surface. When the movable plate moves downward, it drives the sealing plate to flip, and the movable plate drives the push block along the through groove and the movable groove via the guide surface. When the push block moves, it drives the positioning rod toward the avoidance groove, at which time the elastic member 4 deforms. When the positioning rod is aligned with the avoidance groove, the positioning rod releases the limit on the support frame, allowing the support frame to move downward under the drive of the movable plate.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The cylinder cover is used to seal the extraction cylinder and support the storage cylinder via a support plate. The ground phosphorus pentasulfide raw material is fed into the storage cylinder through the feeding section. Initially, the pusher drives the movable plate to move, thereby sealing the open opening. The baffle, under the action of elastic member 1, blocks the discharge port. At this point, the storage cylinder is in a closed state, and the solution and phosphorus pentasulfide mix within the storage cylinder. The solid impurities in the phosphorus pentasulfide are insoluble in the solution. After a period of stagnant time, the solid impurities settle to the lower end of the storage cylinder due to gravity. The support frame supports the sealing plates. When the movable plate contacts the storage cylinder, all sealing plates are tilted, and solid impurities enter the bottom of the storage cylinder through the gaps between adjacent sealing plates and come into contact with the filter screen. When the movable plate contacts the placement cylinder, the cross bar is located at the lower end of the limit slot. At this time, the movable plate is driven downward by the push member, and the cross bar moves relative to the support block along the limit slot. When the movable plate moves, the connecting member drives the sealing plate to rotate, so that the sealing plate rotates to a horizontal state. At this time, all the sealing plates cooperate to seal the solid impurities between the sealing plate and the filter screen. When the cross bar moves to the upper end of the limit slot and contacts the support block, the support block drives the push rod to move through the cross bar, so that the push rod drives the baffle to separate from the drain port, so that the solution flows through the drain port to the drain pipe. The delivery pump is used to improve the discharge efficiency of the solution. At this time, the solution under the sealing plate passes through the filter screen and flows out from the gap between the movable plate and the placement cylinder, thereby completing the filtration of the solution, so that the solid impurities are separated from the solution. The solid impurities are concentrated under the sealing plate. Most of the solution does not need to be filtered when it is discharged, which is beneficial to improve the filtration efficiency of the solution and reduce the influence of impurity solid particles in the solution on the filtration efficiency of the solution.

[0026] 2. The support frame supports the rotating rod. Initially, the polygonal rod is inserted into the limiting hole under the action of elastic member 2. When the rotating rod rotates, the polygonal rod and the limiting hole cooperate to drive the middle plate to rotate, realizing the flipping of the sealing plate. When the filter needs to be replaced, after removing the cylinder cover, move the gripping block along the opening and remove the polygonal rod from the limiting hole. The middle plate and polygonal rod can be separated. After removing the middle plate from the support frame, it is convenient to replace the filter. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0035] The embodiments of the present application disclose a filtering device for preparing butyl ammonium black medicine.

[0036] Example:

[0037] Reference Figure 1 and Figure 2 A filtering device for preparing butyl ammonium black medicine comprises an extraction cylinder 1. The extraction cylinder 1 is hollow and has a cylinder cover 2 at its upper end. Multiple bolts are disposed between the cylinder cover 2 and the extraction cylinder 1. The bolts are arranged circumferentially along the cylinder cover 2 and all of the bolts pass through the cylinder cover 2 and are threadedly connected to the extraction cylinder 1. A placement cylinder 3 is disposed within the extraction cylinder 1, and the extraction cylinder 1 is provided with a support plate 14. The support plate 14 has a placement hole 141 formed vertically therein. The extraction cylinder 1 passes through the placement hole 141 and extends below the support plate 14.

[0038] Reference Figure 2 and Figure 3An extension edge 39 is fixedly provided along the circumference of the upper end of the extraction cylinder 1. The diameter of the extension edge 39 is larger than that of the placement hole 141, and the lower end surface of the extension edge 39 contacts the upper end surface of the support plate 14. A plurality of fixing bolts 391 are provided on the upper end of the extension plate. The fixing bolts 391 pass through the extension plate and are threadedly connected to the support plate 14. The fixing bolts 391 push the extension plate into contact with the support plate 14, thereby securing the placement cylinder 3.

[0039] Reference Figure 1 and Figure 2 The cylinder cover 2 is provided with a feeding portion 21, which includes a feeding barrel 212 and a liquid inlet pipe 211. The feeding barrel 212 is vertically fixed to the upper end of the cylinder cover 2 and is connected to the placement barrel 3. After phosphorus pentasulfide is placed in the feeding barrel 212, the phosphorus pentasulfide enters the placement barrel 3 along the feeding barrel 212. The upper end of the feeding barrel 212 is detachably connected to an end cap, which is used to seal the feeding barrel 212 when no raw materials are needed.

[0040] Reference Figure 1 and Figure 2 The cylinder cover 2 is vertically provided with a feed hole 22, and a stirring tube 23 is disposed within the feed hole 22. The outer circumference of the stirring tube 23 contacts the inner wall of the feed hole 22, so that the stirring tube 23 is rotatably connected to the cylinder cover 2 about its own axis. A rotating member is provided at the upper end of the cylinder cover 2, which is used to drive the stirring tube 23 to rotate. In this embodiment, the rotating member 24 is preferably a motor. The lower end of the stirring tube 23 extends into the placement cylinder 3, and a plurality of stirring blades 231 are circumferentially fixed to the outer side of the stirring tube 23. When the stirring tube 23 rotates, all stirring blades 231 are driven to rotate.

[0041] Reference Figure 1 and Figure 2 The liquid inlet pipe 211 passes through the stirring tube 23 along the axis and is rotatably connected to the stirring tube 23. The cylinder cover 2 is fixed with a support frame 25 for supporting the liquid inlet pipe 211. When the stirring tube 23 rotates, the feed cylinder 212 is positioned. The end of the feed cylinder 212 away from the cylinder cover 2 is connected to a container for storing a protective solvent. The protective solvent is butanol. The protective solvent in the solution storage container enters the storage cylinder 3 through the feed cylinder 212. After phosphorus pentasulfide mixes with the protective solvent, it dissolves in the protective solvent, and solid impurities do not mix with the protective solvent. During the mixing process of phosphorus pentasulfide and the protective solvent, the stirring blade 231 drives the protective solution to flow within the storage cylinder 3, thereby improving the mixing efficiency of phosphorus pentasulfide and the protective solvent.

[0042] Reference Figure 2 and Figure 3The lower end of the placement cylinder 3 is provided with an opening 31, along which a filter screen is positioned. A movable plate 33 is provided at the lower end of the placement cylinder 3, which is vertically and slidably connected to the placement cylinder 3. The extraction cylinder 1 is provided with a pusher 13 for driving the movable plate 33. The pusher 13 comprises a pusher cylinder 131 and a pusher shaft 132. The pusher shaft 132 is located at the lower end of the extraction cylinder 1 and passes vertically through the extraction cylinder 1, slidably connected to the extraction cylinder 1. The pusher cylinder 131 is mounted at the lower end of the extraction cylinder 1 to drive the pusher shaft 132.

[0043] Reference Figure 2 and Figure 3 The lower end of the movable plate 33 is fixed with a straight rod parallel to the driving shaft 132, and a clamping plate 334 is vertically fixed to the lower end of the straight rod. The upper end of the driving shaft 132 is provided with a clamping slot 133, which includes a vertical portion and a horizontal portion. Initially, the clamping plate 334 is located in the horizontal portion of the clamping slot 133 and contacts the inner wall of the horizontal portion. At this time, when the driving shaft 132 moves along the axial direction, the clamping plate 334 drives the movable plate 33 to move. When it is necessary to separate the placement tube 3 and the support plate 14, after releasing the positioning of the placement tube 3 by the fixing bolts 391, the placement tube 3 is rotated in the horizontal direction. The placement tube 3 drives the clamping plate 334 to rotate through the movable plate 33. When the clamping plate 334 is aligned with the vertical portion, the placement tube 3 is moved vertically, so that the clamping plate 334 is separated from the vertical portion and the clamping slot 133, thereby achieving the separation of the movable plate 33 and the driving shaft 132.

The cross bar 324 is inserted into the limiting groove 332 and contacts the inner wall of the limiting groove 332. When the baffle 321 blocks the drain port 32, the cross bar 324 is located at the lower end of the limiting groove 332.

[0046] Reference Figure 2 and Figure 4 A support frame 34 is provided within the placement cylinder 3. An annular groove 36 is defined at the lower end of the support frame 34. The support frame 34 is positioned within the annular groove 36 and is slidably connected to the placement cylinder 3 along the axis of the drive shaft 132. A third elastic member 361 is provided between the support frame 34 and the placement cylinder 3. The third elastic member 361 is a spring, one end of which is fixedly connected to the placement cylinder 3 and the other end to the support frame 34. When the third elastic member 361 is deformed, it drives the support frame 34 away from the filter screen. Multiple sealing plates 4 are provided within the support frame 34, and the multiple sealing plates 4 are evenly arranged in the transverse direction.

The two rotating rods 42 are coaxially arranged, and the intermediate plate 41 is located between the two rotating rods 42. The side of the rotating rod 42 away from the intermediate plate 41 is inserted into the support frame 34 and is vertically connected to the support frame 34 for rotation. The torsion spring 43 is located between the rotating rod 42 and the support frame 34. One end of the torsion spring 43 is fixedly connected to the rotating rod 42, and the other end is fixedly connected to the support frame 34.

[0048] Reference Figure 5 and Figure 6 A polygonal rod 421 is provided at one end of the rotating rod 42 near the middle plate 41. The polygonal rod 421 is slidably connected to the rotating rod 42 along the axis direction. When the rotating rod 42 rotates about its own axis, the polygonal rod 421 is driven to rotate. A limiting hole 411 is provided in the middle plate 41 to match the polygonal rod 421. A second elastic member 422 is provided between the rotating rod 42 and the polygonal rod 421. The second elastic member 422 is a spring. One end of the spring is fixedly connected to the rotating rod 42 and the other end is fixedly connected to the polygonal rod 421. The second elastic member 422 is in a deformed state and applies a thrust to the polygonal rod 421, causing the polygonal rod 421 to be inserted into the limiting hole 411. When the rotating rod 42 rotates, the polygonal rod 421 drives the middle plate 41 to rotate.

[0049] Reference Figure 5 and Figure 6 A gripping block 423 is provided at one end of the polygonal rod 421 away from the rotating rod 42.

An opening 412 is provided in the middle plate 41 along the axis of the rotating rod 42, which is connected to the limiting hole 411. The gripping block 423 passes through the opening 412 and extends outward. The opening 412 is located at the largest end surface of the middle plate 41, making it easy for the operator to move the gripping block 423. When the middle plate 41 and the rotating rod 42 need to be separated, the gripping block 423 is moved along the opening 412 to move the polygonal rod 421 away from the limiting hole 411. After both polygonal rods 421 are separated from the middle plate 41, the middle plate 41 is removed from between the two rotating rods 42.

[0050] Reference Figure 4 and Figure 5 The support frame 34 is provided with two disassembly plates 341, one at each end of the intermediate plate 41 along its length. The disassembly plates 341 are slidably connected to the support frame 34 in the direction toward or away from the intermediate plate 41. A cylindrical block 424 is coaxially fixed to the polygonal rod 421. The cylindrical block 424 passes through the disassembly plates 341 and is rotationally connected to the disassembly plates 341. When the rotating rod 42 drives the polygonal rod 421 to rotate, the cylindrical block 424 rotates relative to the disassembly plates 341 about its own axis. An abutment plate 425 is fixed to the side of the cylindrical block 424 away from the middle plate 41. When the polygonal rod 421 is inserted into the limiting hole 411, the abutment plate 425 abuts against the side of the disassembly plate 341 away from the middle plate 41. When the middle plate 41 needs to be disassembled, the disassembly plate 341 is pushed away from the middle plate 41, thereby driving all the polygonal rods 421 on the same side of the support frame 34 away from the corresponding middle plate 41, which is conducive to improving the convenience of disassembling the middle plate 41.

[0051] Reference Figure 4 and Figure 5 A connecting piece 35 is provided between the movable plate 33 and the middle plate 41. The connecting piece 35 corresponds to the rotating rod 42 one by one. The connecting piece 35 includes a movable rod 351, a rotating plate 352 and a connecting rod 353. The connecting rod 353 is vertically fixed to the outside of the rotating rod 42. When the connecting rod 353 moves, it drives the rotating rod 42 to move. The movable rod 351 passes through the placement tube 3 vertically and is slidably connected to the placement tube 3. The rotating plate 352 is located between the movable rod 351 and the connecting rod 353, and the lower end of the rotating plate 352 is rotatably connected to the movable plate 33, and the upper end is rotatably connected to the connecting rod 353.

[0052] Reference Figure 2 and Figure 5 One end of the movable rod 351 and the rotating plate 352 is fixedly connected to the movable plate 33. When the movable plate 33 moves, the movable rod 351 is driven to move, and the rotating rod 42 is then driven to rotate through the rotating plate 352 and the connecting rod 353. The angle between the intermediate plate 41 and the plane is adjusted by the rotating rod 42. Initially, when the movable plate 33 contacts the lower end of the placement cylinder 3, the intermediate plate 41 is tilted under the action of the torsion spring 43, and the connecting rod 353 tilts upward in a direction away from the intermediate plate 41. At this time, there is a gap between adjacent intermediate plates 41. After the solution in the placement cylinder 3 is left to stand for a standard time, the solid impurities in the solution settle under the action of gravity, pass through the gaps between adjacent intermediate plates 41 along the tilted intermediate plate 41, and finally fall onto the filter screen 311.

[0053] Reference Figure 2 and Figure 4After the static state is completed, the movable plate 33 is driven downward by pushing the cylinder 131, so that the movable plate 33 releases the blockage of the opening 31. After part of the solution passes through the filter 311, it enters the bottom of the extraction cylinder 1 through the gap between the movable plate 33 and the placement cylinder 3. When the movable plate 33 moves, it drives the movable rod 351 to move, and then the rotating plate 352 applies a pulling force to the connecting rod 353, so that the connecting rod 353 drives the rotating rod 42 to rotate. During the rotation of the rotating rod 42, the torsion spring 43 gradually deforms. The placement cylinder 3 is provided with a positioning member 37 for fixing the support frame 34. The positioning member 37 includes a positioning rod 371, a pushing block 372 and an elastic member 373. The movable plate 33 is provided with a through groove 333 in the vertical direction. The placement cylinder 3 is provided with a moving groove 38 corresponding to the through groove 333. The positioning rod 371 passes through the through groove 333 and the moving groove 38 in sequence, and is slidably connected to the placement cylinder 3 along the length direction of the moving groove 38.

[0054] Reference Figure 2 and Figure 4 The placement tube 3 limits the vertical displacement of the positioning rod 371. In the initial state, the upper end of the positioning rod 371 contacts the lower end of the support frame 34, thereby limiting the vertical displacement of the support frame 34. The elastic member 373 is a spring, one end of which is fixedly connected to the positioning rod 371 and the other end is fixedly connected to the placement tube 3, thereby limiting the position of the positioning rod 371. The support frame 34 is provided with an avoidance groove 342 adapted for the positioning rod 371. The avoidance groove 342 is located directly above the movable groove 38 and corresponds to the end of the movable groove 38. When the elastic member 373 is in the natural state, the positioning rod 371 is displaced away from the avoidance groove 342. The pushing block 372 is fixed to the lower end of the positioning rod 371 and is located below the movable plate 33. The pushing block 372 is located on the side of the positioning rod 371 away from the avoidance groove 342, and a guide surface 374 is provided at the upper end of the pushing block 372. The guide surface 374 is tilted from top to bottom in the direction away from the positioning rod 371.

[0055] Reference Figure 2 and Figure 4 When the movable plate 33 is separated from the placing cylinder 3, the movable rod 351 cooperates with the connecting rod 353 to drive the rotating rod 42 to rotate, thereby causing the middle plate 41 to flip over, so that the side of the middle plate 41 facing away from the filter screen 311 flips toward the filter screen 311, thereby reducing the probability of solid impurities staying above the middle plate 41.

[0056] Reference Figure 3 and Figure 4When the movable plate 33 moves, the crossbar 324 moves relative to the support block 331 along the limiting groove 332. At this time, the baffle 321 is stationary. After the movable plate 33 contacts the guide surface 374, the push block 372 drives the positioning rod 371 to move toward the avoidance groove 342. At this time, the positioning rod 371 still limits the support frame 34, so that the support frame 34 remains in the fixed position during the turning process of the intermediate plate 41. When the intermediate plate 41 rotates to the horizontal position, the two adjacent intermediate plates 41 contact each other. At this time, the positioning rod 371 is aligned with the avoidance groove 342, and the crossbar 324 moves to the upper end of the limiting groove 332.

[0057] Reference Figure 2 and Figure 4 , the middle plate 41 rotates to the maximum displacement, at this time the movable plate 33 continues to move downward, thereby driving the support frame 34 to move downward, and at this time the movable plate 33 drives the baffle 321 to move through the push rod 323, so that the baffle 321 is away from the drain port 32, thereby causing the solution above the middle plate 41 to pass through the drain port 32 and fall below the placement cylinder 3. When the solution is discharged, all the middle plates 41 cooperate to separate the placement cylinder 3 into two mutually unconnected cavities, so that the solid impurities remain below the middle plate 41, thereby realizing the separation of the solution and the impurities. When the support frame 34 moves downward, the solution between the filter screen 311 and the middle plate 41 is squeezed through the middle plate 41, thereby accelerating the protective agent solution to pass through the filter screen 311 and complete the filtration.

[0058] Reference Figure 2 and Figure 3 The lower end of the extraction cylinder 1 is connected to a discharge pipe 11, and a delivery pump 12 is installed in the discharge pipe 11. When the solution falls into the lower end of the extraction cylinder 1, the solution is discharged from the extraction tank through the discharge pipe 11 and the delivery pump 12. When separating solid impurities in the solution, the solid impurities are isolated from the pure solution by the intermediate plate 41. At this time, a large amount of solution does not need to be filtered through the filter 311. The solution mixed with solid impurities is pressed and filtered by the intermediate plate 41, thereby accelerating the efficiency of the solution passing through the filter 311. This helps to improve the overall filtration efficiency of the solution and reduce the impact of impurity solid particles in the solution on the solution filtration efficiency.

[0059] The working principle of a filtering device for preparing butyl ammonium black medicine in an embodiment of the present application is as follows: when phosphorus pentasulfide and the protective solution are fully mixed after stirring and standing in the extraction cylinder 1, the movable plate 33 is driven downward by pushing the cylinder 131, so that the movable plate 33 drives the middle plate 41 to flip through the moving rod 351 and the connecting rod 353. The flipped middle plate 41 isolates the settled solid impurities from the solution. When the movable plate 33 moves, it drives the baffle 321 to separate from the placement cylinder 3, and the solution flows into the extraction cylinder 1 through the discharge port 32. When the solution flows, the middle plate 41 prevents the solid impurities from mixing with the solution. The movable plate 33 continues to move downward and drives the middle plate 41 to move downward through the support frame 34, so that the middle plate 41 performs filter pressing on the solution mixed with solid impurities, which is beneficial to improving the filtration efficiency of the solution and reducing the influence of the impurity solid particles in the solution on the filtration efficiency of the solution.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
