Description

Technical Field

[0001] This invention relates to the field of fluidized bed technology, and in particular to a discharge device for a micro fluidized bed and its usage method. Background Technology

[0002] Vibrating fluidized bed dryer is a device that uses vibration and airflow to place moist particles or granular materials into a fluidized state and then dries them with hot air. Because this device combines the advantages of fluidized bed and vibration technology, it can effectively improve drying speed and product quality, and is therefore widely used in pharmaceutical, chemical, food, and metallurgical industries.

[0003] Vibrating fluidized bed dryers typically require a discharge device to facilitate the removal of dried material. Existing discharge devices, such as the one disclosed in patent CN215490960U, which describes a high-efficiency discharge device for fluidized bed drying equipment, achieve the purpose of adjusting the piston position by setting a lead screw, piston, and limit rod, thus facilitating the control of the discharge speed of the discharge device. However, this patent does not screen the dried material. In actual production, if the material dried by the vibrating fluidized bed dryer is not screened, the particle size range of the finished product will vary greatly, which will affect the quality of the final product. At the same time, during material discharge, the material tends to pile up in the collection box. Due to the height of the pile and the influence of gravity, the material at the bottom may be subjected to greater pressure, which will affect the quality of the material at the bottom and lead to product instability. Summary of the Invention

[0004] In order to overcome the shortcomings of existing vibrating fluidized bed dryers in that they cannot screen the dried material and that the material tends to pile up in the collection box during discharge, the purpose of this invention is to provide a discharge device for a micro fluidized bed and its usage method.

[0005] The technical solution is: a discharge device for a micro fluidized bed, including a base, a shell above the base, at least one vibration damping spring on each of the front and rear sides of the base, the two ends of the vibration damping spring being fixedly connected to the base and the shell respectively, at least one vibration motor being installed on each of the front and rear sides of the shell, a discharge pipe being connected to the top surface of the shell, and a square frame being fixedly connected inside the shell, and a flipping component and a dispersing component being arranged inside the square frame;

The second gear meshes with a rack. A flap is fixed to the right side of the second gear. A sliding groove is provided on the left side of the square frame to facilitate the movement of the flap.

[0009] Furthermore, the dispersing component also includes an incomplete gear fixed to the front end of the quantitative turntable shaft and a small gear fixed to the front end of the second lead screw. A transmission gear is provided between the incomplete gear and the small gear. The transmission gear is rotatably connected to the front side of the housing, and the transmission gear meshes with the small gear and the incomplete gear simultaneously.

[0010] Furthermore, the disintegration assembly also includes a mounting box fixed to the rear side of the housing, and a torsion spring is provided inside the mounting box. The two ends of the torsion spring are respectively fixed to the rear end of the second lead screw and the mounting box.

[0011] Furthermore, the rear side of the square frame is open, a fixed baffle is fixedly connected to the rear side of the square frame, a movable baffle is slidably connected to the lower part of the fixed baffle, an elastic element is provided between the movable baffle and the fixed baffle, and the two ends of the elastic element are fixedly connected to the fixed baffle and the movable baffle respectively.

[0012] Furthermore, a material receiving assembly is provided below the square frame. The material receiving assembly includes a first slide rail disposed on the top surface of the base, a first slider slidably connected to the first slide rail, a first support plate fixedly connected to the first slider, two rotors rotatably connected to the inner front wall of the base, the two rotors being connected to each other by a synchronous belt, a first connecting block disposed on the bottom surface of the first support plate, the two ends of the first connecting block being fixedly connected to the first support plate and the synchronous belt respectively, and a second rotary motor is mounted on the front side of the base, the output shaft of the second rotary motor being fixedly connected to the rotor.

[0013] Furthermore, the receiving assembly also includes fixed plates symmetrically fixed to the base. A second slide rail is fixed to the top surface of the two fixed plates.

A second support plate is slidably connected to the upper part of the connecting plate. A guide plate is fixed to the base. The guide plate is provided with a guide groove that is high at both ends and low in the middle. A roller is provided in the guide groove.

A second connecting block is provided on the bottom surface of the connecting plate. The two ends of the second connecting block are respectively fixed to the connecting plate and the timing belt.

[0014] Furthermore, the lower front and rear sides of the housing are rotatably connected to support rods, and the front and rear sides of the base are provided with limiting grooves for the support rods to be supported.

[0015] A method for using a discharge device for a micro fluidized bed includes the following steps:

[0016] S1: Filler: Connect the feed pipe to the outlet of the fluidized bed. The material flows into the feed pipe from the outlet of the fluidized bed and falls onto the metering turntable. When the groove of the metering turntable is filled with material, the first rotary motor starts and drives the metering turntable to rotate 180 degrees, so that the metered material falls onto the turning blade. At the same time, the lower groove rotates to the upper part to continue filling material. While the metering turntable rotates, it drives the incomplete gear to rotate. The incomplete gear drives the transmission gear to rotate through meshing, which in turn drives the small gear to rotate. The rotation of the small gear drives the second lead screw to rotate, so that the torsion spring stores elastic potential energy and causes the second horizontal block to move. While the second horizontal block moves, it drives the second gear to move. At the same time, the second gear rotates through meshing with the rack. The movement and rotation of the second gear drive the flap to move and flip, so that the flap can disperse the falling material.

[0017] S2: Vibration screening: Start the vibration motor, which causes smaller particles to fall through the through holes of the turning blades into the collection box on the second tray and be screened out.

[0018] S3: Replace the collection box: Start the second rotary motor, which drives the rotor to rotate. The rotor rotation drives the synchronous belt to rotate, which in turn causes the first and second trays to move closer together. Then, the L-shaped support block drives the roller to move in the guide groove. Since the guide groove has a structure that is high on both sides and low in the middle, when the first and second trays move closer together, the second tray moves downward, thus completing the replacement of the collection box.

[0019] S4: Discharge: Start the forward and reverse motor, which drives the first lead screw to rotate, causing the first horizontal block to move backward. As the first horizontal block moves, it drives the first gear to move. At the same time, the first gear rotates through meshing with the rack. The direction of rotation is clockwise when viewed from left to right. The movement and rotation of the first gear drive the turning blade to move and turn, so that the material can slide from the turning blade into the collection box on the first pallet.

[0020] The beneficial effects of the present invention are as follows: 1. The present invention is equipped with a flipping component and other components. When the vibration motor is started, the vibration motor drives the flipping blade to vibrate. The through holes on the flipping blade can screen out materials with smaller particle sizes. After screening, the forward and reverse motors are started. The output shafts of the forward and reverse motors are driven by a series of transmissions, so that the flipping blade can move a small distance while rotating. This avoids the accumulation of materials and reduces the pressure on the materials at the bottom, thereby ensuring the quality of the product.

[0021] 2. This invention includes components such as a dispersing assembly. The quantitative turntable has two symmetrically arranged grooves for quantitative measurement. When the upper groove is filled with material, the first rotary motor is started. The output shaft of the first rotary motor rotates, driving the incomplete gear to rotate. The incomplete gear, through a series of transmissions, causes the flap to rotate while moving, thus dispersing the material and preventing it from accumulating during screening. At the same time, when the incomplete gear no longer meshes with the transmission gear, the torsion spring releases its elastic potential energy, causing the second lead screw to rotate in the opposite direction, thereby resetting the flap. The resetting of the flap further disperses the material, thus improving the effect of vibration screening.

[0022] 3. The present invention is equipped with components such as a support rod. When it is necessary to replace the vibration damping spring, the support rod is rotated so that it is inserted into the limiting groove. In this way, the support rod can support the shell, making it easier to replace the vibration damping spring. Attached Figure Description

[0034] The present invention will now be described in detail with reference to the accompanying drawings.

[0035] A discharge device for a micro fluidized bed and its usage method, such as Figures 1-11 As shown, it includes a base 1, a housing 2 is provided on the top of the base 1, at least one damping spring 3 is provided on both the front and rear sides of the base 1, the two ends of the damping spring 3 are fixedly connected to the base 1 and the housing 2 respectively, at least one vibration motor 4 is installed on both the front and rear sides of the housing 2, the top surface of the housing 2 is connected to a feeding pipe 5, the feeding pipe 5 is a telescopic flexible hose, a square frame 6 is fixedly connected inside the housing 2, and a flipping component 7 and a dispersing component 8 are provided inside the square frame 6;

[0036] Furthermore, to prevent material from accumulating during discharge, the flipping assembly 7 includes a first lead screw 71 and a slide rod 72 rotatably connected to the inner wall of the housing 2 and respectively disposed on the left and right sides of the square frame 6. A forward and reverse motor 74 is mounted on the rear side of the housing 2. The rear end of the first lead screw 71 extends out of the housing 2 and is fixedly connected to the output shaft of the forward and reverse motor 74. At least two first horizontal blocks 73 are fitted on both the first lead screw 71 and the slide rod 72, and a turning blade 75 is rotatably connected between the two first horizontal blocks 73. The turning blade 75 is disposed inside the square frame 6, and movable grooves 61 are provided on the left and right sides of the square frame 6 to facilitate the movement of the turning blade 75's rotating shaft. The turning blade 75 is provided with through holes for screening materials. A first gear 76 is rotatably connected to the right side of the left first horizontal block 73, and the first gear 76 is fixedly connected to the rotating shaft of the turning blade 75. A rack 77 is fixedly connected inside the housing 2, and the rack 77 meshes with the first gear 76. During operation... The top surface of the feed pipe 5 is connected to the outlet of the vibrating dryer fluidized bed. The material flows into the feed pipe 5 from the outlet of the vibrating dryer fluidized bed and finally falls onto the turning blade 75. The vibration motor 4 is started, and the vibration motor 4 drives the turning blade 75 to vibrate. The through holes on the turning blade 75 can screen out materials with smaller particle sizes. After screening, the forward and reverse motor 74 is started. The output shaft of the forward and reverse motor 74 rotates, which in turn drives the first lead screw 71 to rotate, causing the first horizontal block 73 to move backward, which in turn drives the first gear 76 to move. While the first gear 76 moves, it rotates through meshing with the rack 77. The direction of rotation is clockwise when viewed from left to right. The movement and rotation of the first gear 76 drive the turning blade 75 to move and turn, so that the material can slide off the turning blade 75. Since the turning blade 75 moves a short distance, the material is prevented from piling up in one place, which reduces the pressure on the material at the bottom and ensures the stability of product quality.

[0037] like Figure 3As shown, in order to maintain the consistency of the output quantity, a metering turntable 10 is rotatably connected inside the shell 2, and the metering turntable 10 is located below the feed pipe 5. A first rotary motor 11 is installed on the rear side of the shell 2. Both the front and rear ends of the rotating shaft of the metering turntable 10 extend out of the shell 2, and the rear end of the rotating shaft of the metering turntable 10 is fixedly connected to the output shaft of the first rotary motor 11. During operation, the material flows into the feed pipe 5 from the discharge port of the vibrating drying fluidized bed and falls onto the metering turntable 10. The metering turntable 10 is symmetrically provided with two grooves for metering. When the upper groove is filled with material, the first rotary motor 11 starts and drives the metering turntable 10 to rotate 180 degrees, so that the metered material falls onto the turning blade 75.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, in order to disperse the material falling onto the turning blade 75 and improve the screening effect, the dispersing component 8 includes a second lead screw 81 rotatably connected to the inner wall of the housing 2. Both ends of the second lead screw 81 extend out of the housing 2. A second horizontal block 82 is threaded on the outer surface of the second lead screw 81. A second gear 83 is rotatably connected to the right side of the second horizontal block 82. The second gear 83 meshes with the rack 77. A flap 84 is fixed to the right side of the second gear 83. A sliding groove 62 is provided on the left side of the square frame 6 to facilitate the movement of the flap 84.

[0039] Furthermore, the dispersing component 8 also includes an incomplete gear 85 fixed to the front end of the rotating shaft of the quantitative turntable 10 and a small gear 86 fixed to the front end of the second lead screw 81. A transmission gear 87 is provided between the incomplete gear 85 and the small gear 86. The transmission gear 87 is rotatably connected to the front side of the housing 2, and the transmission gear 87 meshes with both the small gear 86 and the incomplete gear 85 simultaneously. During operation, the output shaft of the first rotary motor 11 rotates while simultaneously driving the incomplete gear 85 to rotate. The incomplete gear 85, through meshing transmission, further drives the transmission gear 87 to rotate. The transmission gear 87 drives the pinion 86 to rotate through meshing transmission. The rotation of the pinion 86 drives the second lead screw 81 to rotate. At the same time, the rotation of the second lead screw 81 causes the second horizontal block 82 to move. The movement of the second horizontal block 82 drives the second gear 83 to move. The movement of the second gear 83 drives its own rotation through meshing transmission with the rack 77. The movement and rotation of the second gear 83 drive the flap 84 to move and flip. Thus, the flap 84 can disperse the falling material and prevent the material from accumulating during screening, making the vibration screening effect better.

[0040] Furthermore, to prevent the flap 84 from interfering with the flipping blade 75 and to reset the flap 84, the dispersing assembly 8 also includes a mounting box 88 fixed to the rear side of the housing 2. A torsion spring 89 is installed inside the mounting box 88, with both ends of the torsion spring 89 fixed to the rear end of the second lead screw 81 and the mounting box 88, respectively. During operation, the rotation of the second lead screw 81 causes the torsion spring 89 to store elastic potential energy. When the incomplete gear 85 has rotated 180 degrees, the incomplete gear 85 no longer meshes with the transmission gear 87, and the torsion spring 89 releases its elastic potential energy, causing the second lead screw 81 to rotate in the opposite direction, thereby resetting the flap 84. The resetting of the flap 84 can disperse the material once again.

[0041] like Figure 4 and Figure 7 As shown, to facilitate the flipping of the leaf 75, the rear side of the square frame 6 is open, and a fixed baffle 63 is fixedly connected to the rear side of the square frame 6. A movable baffle 64 is slidably connected to the lower part of the fixed baffle 63. The movable baffle 64 is made of lightweight plastic, and an elastic element 65 is provided between the movable baffle 64 and the fixed baffle 63. The two ends of the elastic element 65 are fixedly connected to the fixed baffle 63 and the movable baffle 64, respectively. During operation, when the last leaf 75 moves and flips from front to back, it will squeeze the movable baffle 64, causing the movable baffle 64 to slide upward, thereby squeezing the elastic element 65. When the leaf 75 resets, the elastic element 65 resets, thereby driving the movable baffle 64 to reset.

[0042] like Figure 1 , Figure 9 , Figure 10 and Figure 11 As shown, in order to facilitate material collection, a material collection component 9 is provided below the square frame 6. The material collection component 9 includes a first slide rail 911 provided on the top surface of the base 1, a first slider 912 slidably connected on the first slide rail 911, a first support plate 914 fixedly connected on the first slider 912, two rotors 93 rotatably connected on the inner front wall of the base 1, and the two rotors 93 are connected to each other by a synchronous belt 94. A first connecting block 913 is provided on the bottom surface of the first support plate 914, and the two ends of the first connecting block 913 are fixedly connected to the first support plate 914 and the synchronous belt 94 respectively. A second rotary motor 95 is installed on the front side of the base 1, and the output shaft of the second rotary motor 95 is fixedly connected to the rotor 93.

[0043] Furthermore, to facilitate the replacement of the collection box 15, the material receiving assembly 9 also includes symmetrically fixed plates 921 fixed to the base 1. A second slide rail 922 is fixed to the top surface of the two fixed plates 921. A second slider 923 is slidably connected to the second slide rail 922. A connecting plate 924 is fixed to the second slider 923. A second support plate 925 is slidably connected to the upper part of the connecting plate 924. A guide plate 926 is fixed inside the base 1. The guide plate 926 has a guide groove 9261 that is high at both ends and low in the middle. A roller 929 is installed in the guide groove 9261. One side of the roller 929 is fixed to one end of an L-shaped support block 927. The other end of the L-shaped support block 927 is fixed to the second support plate 925. A second connecting block 928 is installed on the bottom surface of the connecting plate 924. The two ends of the second connecting block 928 are respectively fixed to the connecting plate 924 and the synchronous belt 94. During operation, collection boxes 15 are connected to the upper parts of the first tray 914 and the second tray 925. Small particles of impurities are screened and fall into the collection box 15 of the second tray 925 through the through holes of the turning blade 75. After screening is completed, the second rotary motor 95 is started. The rotation of the second rotary motor 95 drives the rotor 93 to rotate, which in turn drives the synchronous belt 94 to rotate. The rotation of the synchronous belt 94 causes the first tray 914 and the second tray 925 to move closer to each other. Then, the L-shaped support block 927 drives the roller 929 to move in the guide groove 9261. Since the guide groove 9261 is set to be high on both sides and low in the middle, the second tray 925 moves downward while the first tray 914 and the second tray 925 move closer to each other. This avoids interference between the first tray 914 and the second tray 925, thus completing the replacement of the collection box 15.

[0044] like Figure 1 and Figure 2 As shown, the lower front and rear sides of the housing 2 are rotatably connected to support rods 12, and the front and rear sides of the base 1 are provided with limiting grooves 111 for the support rods 12 to support them. When it is necessary to replace the damping spring 3 during operation, the support rods 12 are rotated so that the support rods 12 are inserted into the limiting grooves 111, which can support the housing 2 and make it easier to replace the damping spring 3.

[0045] A method for using a discharge device for a micro fluidized bed includes the following steps:

[0046] S1: Filling: The feed pipe 5 is connected to the outlet of the fluidized bed. The material flows into the feed pipe 5 from the outlet of the fluidized bed and falls onto the metering turntable 10. When the groove of the metering turntable 10 is filled with material, the first rotary motor 11 is started. The first rotary motor 11 drives the metering turntable 10 to rotate 180 degrees, so that the metered material falls onto the turning blade 75. At the same time, the lower groove rotates to the upper part to continue filling material. While the metering turntable 10 rotates, it drives the incomplete gear 85 to rotate. The incomplete gear 85 drives the transmission gear 87 to rotate through meshing transmission, which in turn drives the pinion 86 to rotate. The pinion 86 rotates, which drives the second lead screw 81 to rotate, so that the torsion spring 89 stores elastic potential energy and causes the second horizontal block 82 to move. While the second horizontal block 82 moves, it drives the second gear 83 to move. At the same time, the second gear 83 rotates through meshing transmission with the rack 77. The movement and rotation of the second gear 83 drive the flip plate 84 to move and flip, so that the flip plate 84 can disperse the falling material.

[0047] S2: Vibration screening: Start the vibration motor 4. The vibration motor 4 causes the smaller particles to fall from the through hole of the turning blade 75 into the collection box 15 on the second tray 925 and be screened out.

[0048] S3: Replace collection box 15: Start the second rotary motor 95, which in turn drives the rotor 93 to rotate. The rotor 93 rotates, which in turn drives the synchronous belt 94 to rotate. The synchronous belt 94 rotates, which causes the first tray 914 and the second tray 925 to move closer to each other. Then, the L-shaped support block 927 drives the roller 929 to move in the guide groove 9261. Since the guide groove 9261 has a structure that is high on both sides and low in the middle, when the first tray 914 and the second tray 925 move closer to each other, the second tray 925 moves downward, thus completing the replacement of collection box 15.

[0049] S4: Discharge: Start the forward and reverse motor 74, which drives the first lead screw 71 to rotate, thereby causing the first horizontal block 73 to move backward. While the first horizontal block 73 moves, it drives the first gear 76 to move. At the same time, the first gear 76 rotates by meshing with the rack 77. The direction of rotation is clockwise when viewed from left to right. While the first gear 76 moves and rotates, it drives the turning blade 75 to move and turn, so that the material can slide from the turning blade 75 into the collection box 15 on the first pallet 914.

10. A method of using a discharge device for a micro fluidized bed, characterized in that: The method is applied to a discharge device for a micro fluidized bed as described in claim 9, and the steps are as follows: S1: Filling: Connect the feed pipe (5) to the outlet of the fluidized bed. The material flows into the feed pipe (5) from the outlet of the fluidized bed and falls onto the metering turntable (10). When the groove of the metering turntable (10) is filled with material, the first rotary motor (11) starts. The first rotary motor (11) drives the metering turntable (10) to rotate 180 degrees, so that the metered material falls onto the turning blade (75). At the same time, the lower groove rotates to the upper part to continue filling with material. While the metering turntable (10) is rotating, it drives the incomplete gear (85) to rotate. The incomplete gear (85) meshes with the material. The combined transmission drives the transmission gear (87) to rotate, which in turn drives the pinion (86) to rotate. The rotation of the pinion (86) drives the second lead screw (81) to rotate, causing the torsion spring (89) to store elastic potential energy and causing the second horizontal block (82) to move. The movement of the second horizontal block (82) drives the second gear (83) to move. At the same time, the second gear (83) rotates by meshing with the rack (77). The movement and rotation of the second gear (83) drive the movement and flipping of the flap (84), so that the flap (84) can break up the falling material. S2: Vibration screening: Start the vibration motor (4), the vibration motor (4) causes the smaller particles to fall from the through hole of the turning blade (75) into the collection box on the second tray (925) and be screened out; S3: Replace the collection box: Start the second rotary motor (95), which in turn drives the rotor (93) to rotate. The rotor (93) rotates, which in turn drives the synchronous belt (94) to rotate. The synchronous belt (94) rotates, which causes the first tray (914) and the second tray (925) to move closer to each other. Then the L-shaped support block (927) drives the roller (929) to move in the guide groove (9261). Since the guide groove (9261) has a structure that is high on both sides and low in the middle, when the first tray (914) and the second tray (925) move closer to each other, the second tray (925) moves downward. In this way, the replacement of the collection box can be completed. S4: Discharge: Start the forward and reverse motor (74), which drives the first lead screw (71) to rotate, thereby causing the first horizontal block (73) to move backward. While the first horizontal block (73) moves, it drives the first gear (76) to move. At the same time, the first gear (76) rotates by meshing with the rack (77). The direction of rotation is clockwise when viewed from left to right. While the first gear (76) moves and rotates, it drives the turning blade (75) to move and turn. Thus, the material can slide from the turning blade (75) into the collection box on the first pallet (914).
