Description

Technical Field

[0001] The invention relates to the field of filtering equipment, in particular to a filtering device for preparing butyl ammonium black medicine. 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 needed as raw materials. The production process of phosphorus pentasulfide mainly includes several steps such as raw material preparation - hot melt mixing - heating reaction - tableting and so on. After roller rolling, phosphorus pentasulfide is in flake form.

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

[0004] For related technologies, please refer to the Chinese patent with announcement number CN214861322U, which discloses a small multifunctional extractor capable of tank bottom slag discharge. The device includes: a sandwich tank capable of tank bottom slag discharge, the tank bottom is provided with a filter screen and a heating device; the tank bottom is connected to the material pump through a pipeline and a valve; the tank cover is provided with an exhaust valve, a lighted sight glass and a pressure vacuum gauge; the condenser is connected to the tank cover through a pipeline; the cooler is connected to the condenser; the double-chamber oil-water separator is connected to the cooler; the end of the double-chamber oil-water separator is connected to the sandwich tank. The bracket supports the sandwich tank, and a distribution box is placed on the bracket to connect and control the electrical part. The extractor has good performance and reliable safety.

[0005] With regard to 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 influence 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: 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 provided 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 is moved close 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. A discharge port is opened in the placing cylinder along the circumference, and the discharge port is above the supporting frame. A baffle is provided in the placing cylinder, and the upper end of the baffle is hinged with the placing cylinder. The placing cylinder is provided with an elastic member one, and the elastic member one pushes the baffle to block the discharge port. A push rod is hingedly connected to the lower end of the baffle, and a cross bar is vertically fixed at one end of the push rod away from the baffle. A plurality of support blocks corresponding to the baffle are fixed along the circumference of the movable plate, and a limiting groove is opened in the vertical direction of the support block. The cross bar is inserted in the limiting groove and is slidably connected to the support block along the length direction of the limiting groove.

[0008] By adopting the above technical solution, the cylinder cover is used to seal the extraction cylinder, and the raw material of ground phosphorus pentasulfide is fed into the placement cylinder through the feeding part. Initially, the pusher drives the moving plate to move, thereby blocking the open opening, and the baffle blocks the discharge port under the action of the elastic member 1. At this time, the placement cylinder is in a closed state, and the solution and phosphorus pentasulfide are mixed in the placement cylinder. The solid impurities in the phosphorus pentasulfide are insoluble in the solution. After standing for a period of time, the solid impurities settle to the lower end of the placement cylinder under the action of gravity. The support frame supports the sealing plate. When the moving plate contacts the placement cylinder, all the sealing plates are in an inclined state, and the solid impurities enter the bottom of the placement cylinder along the gap between adjacent sealing plates and contact 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 pusher, and the cross bar moves relative to the support block along the limit slot. When the movable plate moves, the sealing plate is driven to rotate through the connecting member, 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 solutions do not need to be filtered when they are discharged, which is beneficial to improving the filtration efficiency of the solution and reducing the influence of impurity solid particles in the solution on the filtration efficiency of the solution.

[0009] 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 piece 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 a polygonal rod for sliding along the axial direction, and an elastic member two is provided between the polygonal rod and the rotating rod, and the elastic member 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 holding 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 holding 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 for positioning the rotating rod, and when the torsion spring is in a natural state, the intermediate plate is in an inclined state.

[0010] 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 cooperation between the polygonal rod and the limiting hole drives the middle plate to rotate, so as to realize the flipping of the sealing plate. The torsion spring is used to position the rotating rod, and drives the rotating rod and the middle plate to reset after the sealing plate flips. When the filter needs to be replaced, after removing the cylinder cover, the gripping block is moved along the opening, and the polygonal rod is removed from the limiting hole, so that the middle plate and the polygonal rod can be disassembled. After the middle plate is removed from the support frame, it is convenient to replace the filter.

[0011] 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, 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.

[0012] 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 beneficial to improve the work efficiency of disassembling and installing the middle plate.

[0014] 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.

[0015] 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 slidably connected to the placement tube along the vertical direction, an elastic member three is provided between the support frame and the placement tube, 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.

[0016] By adopting the above technical solution, when it is necessary to rotate the sealing plate, the positioning member 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 member releases the positioning of the support frame. When the movable plate moves, it drives the support frame downward, causing the elastic member 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.

[0017] Optionally, the positioning member includes a positioning rod, a pushing block and four elastic members. A moving groove is opened in the horizontal direction at the lower end of the placement tube. The positioning rod passes through the moving groove and is slidably connected with the placement tube along the length direction of the moving groove. When the support frame is in a position, an avoidance groove is opened in the vertical direction of the support frame. One end of the moving groove is located directly below the avoidance groove. The four elastic members are located between the positioning rod and the placement tube, and apply a thrust to the positioning rod away from the avoidance groove. A through groove is opened in the vertical direction of the moving plate. 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.

The raw materials of ground phosphorus pentasulfide are fed into the placement cylinder through the feeding part. Initially, the pusher drives the moving plate to move, thereby blocking the open opening, and the baffle blocks the discharge port under the action of the elastic member 1. At this time, the placement cylinder is in a closed state, and the solution and phosphorus pentasulfide are mixed in the placement cylinder. The solid impurities in phosphorus pentasulfide are insoluble in the solution. After standing for a period of time, the solid impurities settle to the lower end of the placement cylinder under the action of gravity. The support frame supports the sealing plate.

[0045] 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. The gripping block 423 is located at the side of the polygonal rod 421. An opening 412 connected to the limiting hole 411 is provided in the middle plate 41 along the axis direction of the rotating rod 42. The gripping block 423 passes through the opening 412 and extends out of the opening 412. The opening 412 is located at the largest end surface of the middle plate 41, so that it is convenient 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 the two polygonal rods 421 are separated from the middle plate 41, the middle plate 41 is removed from between the two rotating rods 42.

[0046] Reference Figure 4 and Figure 5 The support frame 34 is provided with two disassembly plates 341, which are respectively located at the two ends of the middle plate 41 along the length direction, and the disassembly plates 341 are slidably connected to the support frame 34 in the direction of approaching or moving away from the middle plate 41. A cylindrical block 424 is coaxially fixed to the polygonal rod 421, and the cylindrical block 424 passes through the disassembly plate 341 and is rotatably connected to the disassembly plate 341. When the rotating rod 42 drives the polygonal rod 421 to rotate, the cylindrical block 424 rotates relative to the disassembly plate 341 around its own axis. An abutment plate 425 is fixedly provided on 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.

[0047] 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 outer side of the rotating rod 42. When the connecting rod 353 moves, it drives the rotating rod 42 to move. The movable rod 351 vertically passes through the placement tube 3 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.

[0048] Reference Figure 2 and Figure 5 , one end of the moving rod 351 rotating plate 352 is fixedly connected to the moving plate 33, and when the moving plate 33 moves, the moving rod 351 is driven to move, and then the rotating rod 42 is driven to rotate through the rotating plate 352 and the connecting rod 353, and the angle between the middle plate 41 and the plane is adjusted through the rotating rod 42. Initially, when the moving plate 33 contacts the lower end of the placement cylinder 3, the middle plate 41 is in an inclined state under the action of the torsion spring 43, and the connecting rod 353 is tilted upward in a direction away from the middle plate 41, and there is a gap between adjacent middle plates 41 at this time. 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, and pass through the gaps between adjacent middle plates 41 along the inclined middle plate 41, and finally fall onto the filter screen 311.

[0049] Reference Figure 2 and Figure 4After the static state is completed, the moving plate 33 is driven downward by pushing the cylinder 131, so that the moving plate 33 releases the blockage of the opening 31, and part of the solution passes through the filter 311 and enters the bottom of the extraction tube 1 through the gap between the moving plate 33 and the placement tube 3. When the moving plate 33 moves, it drives the moving 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, and the torsion spring 43 gradually deforms during the rotation of the rotating rod 42. The placement tube 3 is provided with a positioning member 37 for fixing the support frame 34, and the positioning member 37 includes a positioning rod 371, a pushing block 372 and an elastic member 373. The moving plate 33 is provided with a through groove 333 in the vertical direction, and the placement tube 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 with the placement tube 3 along the length direction of the moving groove 38.

[0050] Reference Figure 2 and Figure 4 , the placement tube 3 limits the vertical displacement of the positioning rod 371, and 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 positioning rod 371. The support frame 34 is provided with an avoidance groove 342 adapted to the positioning rod 371, the avoidance groove 342 is located directly above the moving groove 38, and corresponds to the end of the moving groove 38. In the natural state of the elastic member 373, the positioning rod 371 is in a displacement 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 inclined from top to bottom in a direction away from the positioning rod 371.

[0051] 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, so that the side of the middle plate 41 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.

[0052] Reference Figure 3 and Figure 4When the moving plate 33 moves, the cross bar 324 moves relative to the support block 331 along the limiting groove 332. At this time, the baffle 321 is in a stationary state. After the moving plate 33 contacts the guide surface 374, the positioning rod 371 is driven to move toward the avoidance groove 342 through the push block 372. At this time, the positioning rod 371 still limits the support frame 34, so that the support frame 34 remains in a positioned state during the flipping process of the middle plate 41. When the middle plate 41 rotates to a horizontal state, the two adjacent middle plates 41 collide with each other. At this time, the positioning rod 371 is opposite to the avoidance groove 342, and the cross bar 324 moves to the upper end of the limiting groove 332.

[0053] Reference Figure 2 and Figure 4 , the middle plate 41 rotates to the maximum displacement, at which time the movable plate 33 continues to move downward, thereby driving the support frame 34 to move downward. 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 discharge port 32, and then the solution above the middle plate 41 passes through the discharge port 32 and falls to the bottom of the placement tube 3. When the solution is discharged, all the middle plates 41 cooperate to separate the placement tube 3 into two cavities that are not connected to each other, so that the solid impurities stay under 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.

[0054] 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 on the discharge pipe 11. When the solution falls into the lower end of the extraction cylinder 1, the solution is delivered from the extraction tank through the discharge pipe 11 and the delivery pump 12. When the solid impurities in the solution are separated, the solid impurities are isolated from the pure solution through the middle plate 41. At this time, a large amount of solution does not need to be filtered through the filter screen 311, and the solution mixed with the solid impurities is filtered by the middle plate 41, thereby accelerating the efficiency of the solution passing through the filter screen 311, which is conducive to improving the overall filtration efficiency of the solution and reducing the influence of the impurity solid particles in the solution on the solution filtration efficiency.

[0055] 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, and the flipped middle plate 41 isolates the settled solid impurities from the solution, and the movable plate 33 drives the baffle 321 to separate from the placement cylinder 3 when moving, 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, and 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 pressure filtering on the solution mixed with solid impurities, which is beneficial to improve the filtration efficiency of the solution and reduce the influence of the impurity solid particles in the solution on the filtration efficiency of the solution.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
