Description

Technical Field

[0001] The invention relates to the technical field of dust conveying, and in particular to a conveying device capable of continuously spraying dust. Background Art

[0002] The fluidity of powder is related to the shape, size, surface state, density, porosity, etc. of the particles, as well as the complex relationship between the internal friction and adhesion between particles. The fluidity of powder cannot be expressed by a single physical property value. However, the fluidity of powder has a great influence on the weight difference of preparations such as granules, capsules, and tablets, and is an important link in ensuring product quality.

[0003] Existing methods for testing powder fluidity can be divided into gravity flow method, vibration flow method, compression flow method and fluidization flow method, among which fluidization flow method generally refers to solid fluidization, also known as pseudo-liquefaction, which utilizes the effect of flowing fluid to suspend solid particles so that the solid particles have certain fluid surface characteristics. The contact between the fluid and the solid is used to realize the operation of the production process, which is called fluidization technology. However, during the contact process with air fluid, dust is easily contacted with moisture in the air, thereby causing dust agglomeration, which makes it impossible for subsequent dust to flow smoothly.

[0031] An annular plate 511 is fixedly installed on the inner side of the conical cover 59, a sleeve 512 is fixedly installed through the center of the annular plate 511, a reciprocating screw 516 is installed through the inner side of the sleeve 512, a heater 517 is fixedly installed on the top of the reciprocating screw 516, a column 513 is fixedly installed on the bottom end of the reciprocating screw 516, a plurality of diagonal support rods 514 are fixedly installed on the side of the column 513, the bottom ends of the plurality of diagonal support rods 514 are fixedly connected to the inner wall of the conical portion 43, a wire tube 515 is also fixedly installed on the side of the column 513, the wire tube 515 passes through the conical portion 43 and is fixedly connected to the conical portion 43.

[0032] Furthermore, the wire on the heater 517 passes through the reciprocating screw rod 516 and the column 513 and finally leaks out of the wire tube 515 .

[0033] The drying and crushing mechanism 5 also includes an exhaust pipe 518 that passes through the conical portion 43 and is fixedly connected to the conical portion 43. The top end of the exhaust pipe 518 passes through the elbow 6 and is fixedly connected to the elbow 6. A cylindrical filter bag 519 is fixedly installed between the bottom end of the exhaust pipe 518 and the bottom of the conical cover 59.

[0034] A brush strip 520 is fixedly mounted on the side of the transmission tube 51 , and the brush strip 520 is slidably connected to the bottom of the filter plate 41 .

[0035] Furthermore, during the rotation of the transmission tube 51, the brush strip 520 will be driven to rotate, and the rotating brush strip 520 can clean the bottom of the filter plate 41, thereby sweeping off the dust attached to the bottom of the filter plate 41, thereby ensuring that the filter plate 41 always has better air permeability.

[0036] In this embodiment: when in use, the dust in the ash storage hopper 4 falls into the horizontal pipe 71 through the vertical pipe 1 72, and then the motor 2 75 is started, the motor 2 75 rotates and drives the auger 74 to rotate, the auger 74 rotates and transports the dust falling into the horizontal pipe 71 to the side of the vertical pipe 2 73, and with the transportation of the auger 74, the dust in the horizontal pipe 71 will fall out of the vertical pipe 2 73 and fall into the connecting pipe 21 through the ash inlet pipe 24;

[0037] Continuing with the above, the motor 2 75 is started and the fan 3 is started at the same time. After being blown by the fan 3, the air flows from the air inlet pipe 22 to the side of the ash outlet pipe 23. In this process, the airflow carries the dust falling into the connecting pipe 21 and circulates synchronously. Then, the air carries the dust into the curved pipe 6 and finally into the ash storage hopper 4. The dust is filtered by the filter plate 41 and accumulated in the ash storage hopper 4. The air is then directly discharged through the pores of the filter plate 41.

[0038] The dust easily becomes moist and lumps due to contact with moisture in the air. When the fan 3 is started, the motor 1 56 is started at the same time. The motor 1 56 rotates and drives the bevel gear 1 54 to rotate through the bevel gear 3 57. The bevel gear 1 54 then drives the transmission tube 51 to rotate. The transmission tube 51 then drives the spiral blade 52 to rotate. The rotating spiral blade 52 can stir the dust in the ash storage hopper 4. As the spiral blade 52 rotates, it can break up some of the lumped dust and drive some of the lumped dust to move from top to bottom.

[0039] During the rotation of the transmission tube 51, the conical cover 1 58 will be driven to rotate synchronously. During the rotation of the conical cover 1 58, the unagglomerated dust will pass through the multiple bevel holes 581 and fall onto the conical cover 2 59. During the rotation of the conical cover 1 58, the agglomerated dust in contact with the conical cover 1 58 can be cut by the edge edges of the multiple bevel holes 581. The shredded dust will then pass through the bevel holes 581 and fall onto the conical cover 2 59.

[0040] During the rotation of bevel gear three 57, transmission shaft 53 will be driven to rotate through bevel gear two 55, and transmission shaft 53 will then drive cone cover two 59 to rotate through prism 510, and cone cover two 59 will be driven to rotate through annular plate 511 during the rotation of cone cover two 59. Through the cooperation of sleeve 512 and reciprocating screw rod 516, sleeve 512 will drive annular plate 511 to move up and down, and annular plate 511 will then drive cone cover two 59 to move up and down simultaneously during the self-rotation process, and cone cover two 59 and cone cover one 58 have opposite rotation directions;

[0041] The conical cover 1 58 and the conical cover 2 59 rotating in opposite directions can crush the dust falling on the conical cover 2 59, so that the agglomerated dust that is not completely crushed by the oblique cut hole 581 can be completely crushed. At the same time, the heat generated by the heater 517 is transferred to the dust falling on the conical cover 2 59 through the conical cover 2 59 to complete the heating of the dust. In addition, since the gap between the conical cover 1 58 and the conical cover 2 59 is small, it is ensured that the dust falling on the conical cover 2 59 is a thin layer, so that the dust can be fully and evenly heated.

[0042] After that, the crushed and dried dust will fall onto the inner wall of the conical part 43 through the gap at the bottom of the conical cover 1 58 and the conical cover 2 59, and finally fall into the vertical pipe 1 72 along the inner wall of the conical part 43. In the process of air flowing from the ash outlet pipe 23 through the elbow 6 and entering the ash storage hopper 4, the air in the exhaust pipe 518 will be discharged from the top and enter the elbow 6, thereby forming a negative pressure at the bottom of the exhaust pipe 518. At this time, the moisture generated by the drying dust will enter the exhaust pipe 518 through the cylindrical filter bag 519 and be finally discharged. For the dust adhering to the cylindrical filter bag 519, the cylindrical filter bag 519 will be continuously squeezed and stretched during the up and down movement of the conical cover 2 59, so that the dust adhering to the cylindrical filter bag 519 can be shaken off, ensuring that the cylindrical filter bag 519 always has the better dust filtering function.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
