Description

Technical Field

[0001] The utility model relates to a high-efficiency drying device for acetamiprid granules, and in particular to a high-efficiency drying device for acetamiprid granules used in the field of drying equipment. Background Art

[0002] Drying of acetamiprid granules is an important step in the production process of acetamiprid. Acetamiprid granules usually contain a certain amount of moisture during the production process. The main purpose of drying is to remove this moisture so that the granules reach the specified moisture content standard.

[0003] The specification of Chinese patent CN208817923U discloses a acetamiprid granule drying tower, including a drying tower, a support column fixedly installed at the bottom end of the drying tower, a motor fixedly installed at the top end of the drying tower, and a rotating shaft fixedly installed in the middle of the drying tower. The utility model maintains a sterile environment in the tower by arranging a sterilization lamp in the drying tower to prevent the acetamiprid granules from being infected by bacteria. A motor is installed at one end of the placement rod, and the granule placement rack is installed on the rotating shaft. The granule placement rack and the placement rod are rotated at all times, so that the granules are heated evenly and dried more thoroughly.

[0004] During the drying process, when some particles clump and stick together during rolling, only the outer particles of this part of the material can directly contact the hot air, while the inner particles are blocked and cannot fully exchange heat with the hot air, which will greatly reduce the heat transfer efficiency. Therefore, it is necessary to design an efficient drying equipment for acetamiprid particles with screening function to solve the above problems. Summary of the Invention

[0005] In response to the above-mentioned existing technology, the technical problem to be solved by the present invention is that during the drying process, when some particles clump and stick together during the rolling process, only the outer particles of this part of the material can directly contact the hot air, while the inner particles are blocked and cannot fully exchange heat with the hot air, which will greatly reduce the heat transfer efficiency.

[0006] In order to solve the above problems, the utility model provides a high-efficiency drying equipment for acetamiprid granules, including a drying drum machine, a transverse roller is provided in the middle of the inner end of the drying drum machine, the transverse roller extends to the rear side of the drying drum machine, the lower end of the transverse roller is fixedly connected to the rear side vertical plate, the upper end of the transverse roller is installed with a hollow bottom frame, the upper end of the hollow bottom frame is fixedly connected to a U-shaped top rod, the upper end of the U-shaped top rod is symmetrically fixedly connected with springs on the left and right sides, the upper ends of the two springs are fixedly connected with a mesh screen plate, and multiple rotating shafts are installed on the front and rear sides of the transverse rod of the U-shaped top rod.

[0007] In the above-mentioned high-efficiency drying equipment for acetamiprid granules, this solution uses a mesh screen plate to screen the agglomerated acetamiprid granular material so that it is no longer in agglomerated state, so that the acetamiprid granular material can be evenly exposed to the hot air in the drying drum during the remaining drying time, thereby ensuring the heat transfer effect.

[0008] As a further improvement of the present application, the outer end of the rotating shaft is rotatably connected to a shaking side block, and the drying drum machine is externally connected to a motor.

[0009] As a further improvement of the present application, a pair of metal corrugated material guide plates are fixedly connected between the two corresponding front and rear rocking side blocks, and the metal corrugated material guide plates are located directly below the mesh screen plate.

[0010] As a further improvement of the present application, a pair of metal corrugated material guide plates are fixedly connected to a plurality of flexible protruding sheets at their ends close to each other.

[0011] As another improvement of the present application, a plurality of flexible protruding sheets are staggered from top to bottom, and the lower end of the transverse roller is fixedly connected to a triangular base.

[0012] As another improved supplement of the present application, an arc-shaped lower groove is provided at the lower end of the hollow bottom frame.

[0013] As another improved supplement of the present application, the inner end of the drying drum is filled with a plurality of acetamiprid granular materials.

[0014] In summary, in this scheme, when the acetamiprid granular material follows the drying drum machine to the highest point and is thrown down, the springs at both ends of the material will generate elastic force, which can cause the surface of the mesh screen plate to shake up and down, assisting the acetamiprid granular material to pass through the position between the mesh screen plates, and then use the mesh screen plate to screen the agglomerated acetamiprid granular material so that it is no longer in a clumping state, so that the acetamiprid granular material can be evenly contacted with the hot air in the drying drum machine during the remaining drying time, so that the heat transfer effect is guaranteed. After the acetamiprid granular material is screened through the mesh screen plate, it can also pass through the space between a pair of metal corrugated guide plates, thereby extending the residence time of the acetamiprid granular material in the hot air. At the same time, the metal corrugated guide plates have good thermal conductivity, which can increase the hot air contact surface of the acetamiprid granular material, thereby improving the drying efficiency.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-5 The present invention shows an efficient drying device for acetamiprid granules, comprising a drying drum machine 1, a transverse roller 3 is provided in the middle of the inner end of the drying drum machine 1, the transverse roller 3 extends to the rear side of the drying drum machine 1, the lower end of the transverse roller 3 is fixedly connected to the rear side vertical plate 2, the upper end of the transverse roller 3 is installed with a hollow bottom frame 6, the upper end of the hollow bottom frame 6 is fixedly connected to a U-shaped top rod 7, the upper end of the U-shaped top rod 7 is symmetrically fixedly connected to springs 8 on the left and right sides, the upper ends of the two springs 8 are fixedly connected to a mesh screen plate 9, and a plurality of rotating shafts 11 are installed on the front and rear sides of the transverse rod of the U-shaped top rod 7.

[0027] Figure 1-5 It is shown that the outer end of the rotating shaft 11 is rotatably connected to the shaking side block 10, and the drying drum machine 1 is externally connected to a motor. A pair of metal corrugated material guide plates 12 are fixedly connected between the two corresponding front and rear shaking side blocks 10. The metal corrugated material guide plates 12 are located directly below the mesh screen plate 9. The ends of the pair of metal corrugated material guide plates 12 that are close to each other are fixedly connected to multiple flexible protruding sheets 13. The multiple flexible protruding sheets 13 are staggered from top to bottom. The inner end of the drying drum machine 1 is filled with a number of acetamiprid granular materials.

[0028] Figure 1-5 The present invention shows that the acetamiprid granules are filled into the drying drum machine 1 and the heated air is evenly blown into the drying drum machine 1 to exchange heat with the acetamiprid granules. The drying drum machine 1 uses an external motor to drive its rotation and continuously flip the granules so that the granules are fully exposed to the hot air and are dried smoothly. A transverse roller 3 is provided through the drying drum machine 1. The mesh screen plate 9 on the transverse roller 3 is provided just below the inner top wall of the drying drum machine 1. When the acetamiprid granules follow the drying drum machine 1 to rotate to the highest point and are thrown down, the acetamiprid granules can first be After falling onto the mesh screen plate 9 and the mesh screen plate 9 contacts the heavy acetamiprid granular material, the springs 8 at both ends will generate elastic force, which can make the surface of the mesh screen plate 9 shake up and down, and assist the acetamiprid granular material to pass through the position between the mesh screen plates 9, and then use the mesh screen plate 9 to screen the acetamiprid granular material in a clumping state, so that it is no longer in a clumping state, so that the acetamiprid granular material can be evenly contacted with the hot air in the drying drum machine 1 during the remaining drying time, so that the heat transfer effect is guaranteed, and the acetamiprid granular material passes through the mesh screen plate 9. After the sieve plate 9 is screened, it can also pass through the space between a pair of metal corrugated guide plates 12. First, the tortuous path between the two metal corrugated guide plates 12 will change the falling trajectory of the acetamiprid granular material, prolonging the residence time of the acetamiprid granular material in the hot air. At the same time, the metal corrugated guide plates 12 have good thermal conductivity, which can increase the hot air contact surface of the acetamiprid granular material, thereby improving the drying efficiency. At the same time, the flexible protruding sheet 13 on the inner side of the metal corrugated guide plate 12 can make the falling path of the acetamiprid granular material more tortuous, making the acetamiprid granular material more tortuous. The acetamiprid granular material stays longer between the two metal corrugated guide plates 12. At the same time, when the metal corrugated guide plates 12 are set in the drying drum machine 1, the upper part of the metal corrugated guide plates 12 has a falling vibration force from the acetamiprid granular material. The shaking side blocks 10 on the metal corrugated guide plates 12 can generate a left and right swing amplitude through the metal corrugated guide plates 12, which can guide the flow of hot air, improve the hot air circulation efficiency inside the drying drum machine 1, and further improve the drying efficiency of the drying drum machine 1 for the acetamiprid granular material.

[0029] Second implementation method:

[0030] Figure 6-7 The present invention shows an efficient drying equipment for acetamiprid granules, wherein the lower end of the transverse roller 3 is fixedly connected to a triangular base 4, and the lower end of the hollow bottom frame 6 is provided with an arc-shaped lower groove 5, and the transverse roller 3 and the hollow bottom frame 6 can be connected to each other through the transverse roller 3 and the arc-shaped lower groove 5. The transverse roller 3 can swing left and right in the arc-shaped lower groove 5 following the falling force of the acetamiprid granule material, and the swinging force can be used to prevent the accumulation of particles from clogging the screen, thereby assisting in driving the air flow and improving the heat transfer efficiency in the drying drum machine 1.

[0031] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
