The dryer vaporizes the moisture in the material by heating to obtain solid materials with a specified moisture content. The purpose of drying is for the use of materials or further processing. According to the operating pressure, the dryer is divided into two categories: atmospheric pressure dryer and vacuum dryer. According to the operating pressure, it can be divided into atmospheric pressure and reduced pressure. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a masterbatch crystallization drying furnace, which solves the problem of masterbatch particle volume reduction and clogging of the screen due to evaporation of water during the drying process, and how to automatically clean the masterbatch falling into the air duct.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a masterbatch crystallization drying furnace, comprising a device body, a feed wall is fixedly connected to the upper position of the device body surface, a discharge pipe and a backflow prevention mechanism are fixedly connected to the bottom of the device body, and an anti-blocking mechanism is fixedly connected to the inner side of the device body. The anti-blocking mechanism includes a first mesh plate and a second mesh plate, the surfaces of the first mesh plate and the second mesh plate are fixedly connected to the inner side of the device body, a rubber block is fixedly connected to the middle position of the opposite surface of the first mesh plate and the second mesh plate, and a cylinder is fixedly connected to the surface of the rubber block near the device body, and the activity at the output end of the cylinder A stabilizing component is provided on the surface of the plug rod, and a dredging component is fixedly connected to the surface of the stabilizing component.

Two wind tubes are arranged to introduce heated air into the interior of the device body to dry the masterbatch. The obliquely arranged mesh plate allows the masterbatch to be discharged from the discharge pipe, and the piston rod at the output end of the cylinder drives the dredging component to move between the first mesh plate and the second mesh plate. The masterbatch that has reduced in volume and blocked the mesh plate is dredged and falls into the wind tube, thereby solving the problem of the masterbatch particles being reduced in volume and blocking the mesh plate due to the evaporation of water during the drying process.

[0005] Preferably, an observation glass is fixedly connected to the surface of the device body, and the stabilizing component includes a rotating wall, the surface of the rotating wall is fixedly connected to the surface of the piston rod at the output end of the cylinder, and the inner side surface of the rotating wall is rotatably connected to a gear rod.

The gear rod is meshed with the surface of the rack through the gear, and the masterbatch is blown upward by the air cylinder. The drying process of the masterbatch can be observed through the observation glass. When the rotating cylinder rotates, the rubber strip and the metal strip extend into the mesh holes on the surface of the screen plate to clear the clogged masterbatch. The cylinder drives the rotating wall to move obliquely upward along the rack. Since the rotating wall and the gear rod are rotationally connected, and the gear on the surface of the gear rod is meshed with the rack, the atomizing nozzle sprays lubricating oil to lubricate the meshing position, so that the gear rod can rotate stably obliquely upward. The mutual meshing of the gear and the rack makes the gear rod drive the rotating cylinder to rotate more smoothly and reliably.

[0007] Preferably, the dredging component includes a rotating cylinder, the surface of the rotating cylinder is fixedly connected to the surface of the gear rod, the inner side surface of the rotating cylinder is fixedly connected with an embedded wall, the surface of the embedded wall is fixedly connected with a rubber strip, the embedded wall is embedded in the inner side surface of the rotating cylinder, and the rubber strip and the metal strip extend into the mesh holes of the mesh plate to dredge the masterbatch, which can effectively prevent the rubber strip from detaching from the rotating cylinder. The metal strip is made of beryllium copper alloy and has good elasticity, thereby achieving a better dredging effect. When the masterbatch falls from the mesh to the bottom of the inner side surface of the straight-through pipe, the damping rotor is manually rotated so that the heated air is discharged from the control valve, and the masterbatch enters the cleaning wall through the control valve, and the heated air is discharged from the perforated cylinder. The spiral blades reduce the kinetic energy of the masterbatch and collect it in the perforated cylinder, thereby automatically collecting the fallen masterbatch.

[0010] Preferably, one end of the connecting pipe away from the wind cylinder is fixedly connected to a straight-through pipe, the surface of the connecting pipe is fixedly connected to a detection component, the detection component includes a damping rotator, the surface of the damping rotator is fixedly connected to the surface of the connecting pipe, and the output end of the damping rotator is fixedly connected to a rubber disk.

Since the control valve is close to the bottom of the connecting pipe, the masterbatch falls to a position close to the control valve. In order to prevent the heated air from blowing the masterbatch back into the device body through the straight-through pipe, the damping rotator is manually rotated at regular intervals, and the shaft at the output end of the damping rotator drives the rubber disc to rotate on the inner side of the connecting pipe. The rubber disc and the sealing strip block the heated air, and the heated air hits the surface of the rubber disc. The pressure detector detects the pressure on the surface of the rubber disc, and the output of the pressure detector causes the control valve to open, and the heated air carries the masterbatch through the control valve, thereby automatically cleaning the masterbatch.

[0013] Preferably, the output end of the control valve is fixedly connected with a cleaning wall, the inner side surface of the cleaning wall is fixedly connected with a spiral sheet, and the surface of the cleaning wall away from the control valve is fixedly connected with an open hole cylinder.

[0014] The present invention provides a masterbatch crystallization drying furnace. It has the following beneficial effects:

[0015] 1. The masterbatch crystallization drying furnace has a first mesh plate and a second mesh plate which are arranged obliquely on the inner side of the device body. The feed wall puts the wet masterbatch into the device body. Two wind tubes are arranged to introduce heated air into the interior of the device body to dry the masterbatch. The obliquely arranged mesh plates allow the masterbatch to be discharged from the discharge pipe. The piston rod at the output end of the cylinder drives the dredging component to move between the first mesh plate and the second mesh plate. The masterbatch that has reduced in volume and blocked the mesh plate is dredged and falls into the wind tube, thereby solving the problem that the masterbatch particles are reduced in volume and blocked the mesh plate due to the evaporation of water during the drying process.

[0016] 2. In the masterbatch crystallization drying furnace, the masterbatch is blown upward by the wind tube, and the drying process of the masterbatch can be observed through the observation glass. When the rotating drum rotates, the rubber strips and metal strips extend into the mesh holes on the surface of the screen plate to clear the blocked masterbatch. The cylinder drives the rotating wall to move obliquely upward along the rack. Since the rotating wall and the gear rod are rotatably connected, and the gear on the surface of the gear rod is meshed with the rack, the atomizing nozzle sprays lubricating oil to lubricate the meshing position, so that the gear rod can rotate stably obliquely upward. The mutual meshing of the gear and the rack makes the gear rod drive the rotating drum to rotate more smoothly and reliably.

[0017] 3. In the masterbatch crystallization drying furnace, the masterbatch is introduced into the device body through the feed wall, the masterbatch is thrown upward by the heated wind at the position above the first mesh plate, and the dredging component rotates between the first mesh plate and the second mesh plate, thereby dredging the masterbatch that blocks the mesh plate due to the reduction in volume and falling into the wind tube, and the masterbatch falls into the position near the cleaning component through the wind tube and the straight-through pipe. After the device has been used for a period of time, the straight-through pipe is manually blocked by the detection component, and the hot air entering through the straight-through pipe is discharged by the cleaning component, thereby automatically discharging the masterbatch near the cleaning component. This method does not require shutdown for manual cleaning, thereby saving resources.

[0018] 4. In the masterbatch crystallization drying furnace, the unblocked masterbatch falls into the air duct from the second mesh plate. Since the control valve is close to the bottom of the connecting pipe, the masterbatch falls to a position close to the control valve. In order to prevent the heated air from blowing the masterbatch back into the device body through the straight pipe, the damping rotator is manually rotated at regular intervals. The shaft at the output end of the damping rotator drives the rubber disc to rotate on the inner side of the connecting pipe. The rubber disc and the sealing strip block the heated air. The heated air hits the surface of the rubber disc. The pressure detector detects the pressure on the surface of the rubber disc. The output of the pressure detector causes the control valve to open. The heated air carries the masterbatch through the control valve, thereby automatically cleaning the masterbatch.

[0019] 5. The masterbatch crystallization drying furnace has an embedded wall embedded in the inner side of the rotating cylinder. When the rubber strip and the metal strip extend into the mesh of the screen plate to dredge the masterbatch, the rubber strip can be effectively prevented from being separated from the rotating cylinder. The metal strip is made of beryllium copper alloy and has good elasticity, thereby making the dredging effect better. When the masterbatch falls from the mesh to the bottom of the inner side of the straight-through pipe, the damping rotor is manually rotated to discharge the heated air from the control valve, and the masterbatch enters the cleaning wall through the control valve. The heated air is discharged from the perforated cylinder, and the spiral blade reduces the kinetic energy of the masterbatch and collects it in the perforated cylinder, thereby automatically collecting the fallen masterbatch.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1-Figure 3 As shown, the present invention provides a technical solution: a masterbatch crystallization drying furnace, comprising a device body 1, a feed wall 2 is fixedly connected to the upper position of the surface of the device body 1, a discharge pipe 4 and an anti-backflow mechanism 6 are respectively fixedly connected to the bottom of the device body 1, an anti-blocking mechanism 5 is fixedly connected to the inner side of the device body 1, and the anti-blocking mechanism 5 comprises a first mesh plate 51 and a second mesh plate 52, the surfaces of the first mesh plate 51 and the second mesh plate 52 are both fixedly connected to the inner side of the device body 1, a rubber block 53 is fixedly connected to the middle position of the opposite surfaces of the first mesh plate 51 and the second mesh plate 52, a cylinder 54 is fixedly connected to the surface of the rubber block 53 near the device body 1, a stabilizing component 55 is provided on the surface of the piston rod of the output end of the cylinder 54, a dredging component 56 is fixedly connected to the surface of the stabilizing component 55, and a wind tube 62 is fixedly connected to the bottom of the device body 1.

[0032] When in use, the first mesh plate 51 and the second mesh plate 52 are obliquely arranged on the inner side of the device body 1, the feed wall 2 puts the wet masterbatch into the device body 1, and two wind tubes 62 are arranged to introduce heated air into the interior of the device body 1, so as to dry the masterbatch. The obliquely arranged mesh plates allow the masterbatch to be discharged from the discharge pipe 4, and the piston rod at the output end of the cylinder 54 drives the dredging component 56 to move between the first mesh plate 51 and the second mesh plate 52. The masterbatch that has reduced in volume and blocked the mesh plate is dredged and falls into the wind tube 62, thereby solving the problem that the masterbatch particles are reduced in volume and blocked in the mesh plate due to the evaporation of water during the drying process.

[0035] When in use, the masterbatch is blown upward by the air cylinder 62, and the drying process of the masterbatch can be observed through the observation glass 3. When the rotating cylinder 561 rotates, the rubber strip 563 and the metal strip 564 extend into the mesh holes on the surface of the screen, thereby clearing the clogged masterbatch. The cylinder 54 drives the rotating wall 551 to move obliquely upward along the rack 553. Since the rotating wall 551 is rotationally connected to the gear rod 552, and the gear on the surface of the gear rod 552 is meshed with the rack 553, the atomizing nozzle 554 sprays lubricating oil to lubricate the meshing position, so that the gear rod 552 can rotate stably obliquely upward. The mutual meshing of the gear and the rack 553 makes the gear rod 552 drive the rotating cylinder 561 to rotate more stably and reliably.

[0038] When in use, the masterbatch is introduced into the device body 1 through the feed wall 2, and the masterbatch is thrown upward by the heated wind at the position above the first mesh plate 51. The dredging component 56 rotates between the first mesh plate 51 and the second mesh plate 52, so that the masterbatch that blocks the mesh plate due to the reduction in volume is dredged and falls into the wind tube 62. The masterbatch falls into the position near the cleaning component 66 through the wind tube 62 and the straight-through pipe 64. After the device has been used for a period of time, the straight-through pipe 64 is manually blocked by the detection component 65, and the hot air entering from the straight-through pipe 64 is discharged by the cleaning component 66, thereby automatically discharging the masterbatch near the cleaning component 66. This method does not require shutdown for manual cleaning, thereby saving resources.

[0041] During use, the dredged masterbatch falls into the air duct 62 from the second mesh plate 52. Since the control valve 661 is close to the bottom of the connecting pipe 63, the masterbatch falls to a position close to the control valve 661. In order to prevent the heated wind from blowing the masterbatch back into the device body 1 through the straight pipe 64, the damping rotator 651 is manually rotated at regular intervals. The shaft at the output end of the damping rotator 651 drives the rubber disc 652 to rotate on the inner side of the connecting pipe 63. The rubber disc 652 and the sealing strip 654 block the heated wind. The heated wind hits the surface of the rubber disc 652. The pressure detector 653 detects the pressure on the surface of the rubber disc 652. The output of the pressure detector 653 causes the control valve 661 to open. The heated wind carries the masterbatch through the control valve 661, thereby automatically cleaning the masterbatch.

[0044] When in use, the embedded wall 562 is embedded in the inner side of the rotating cylinder 561. When the rubber strip 563 and the metal strip 564 extend into the mesh of the screen plate to dredge the masterbatch, the rubber strip 563 can be effectively prevented from separating from the rotating cylinder 561. The metal strip 564 is made of beryllium copper alloy and has good elasticity, thereby achieving a better dredging effect. When the masterbatch falls from the mesh to the bottom of the inner side of the straight-through pipe 64, the damping rotator 651 is manually rotated to discharge the heated air from the control valve 661. The masterbatch enters the cleaning wall 662 through the control valve 661, and the heated air is discharged from the perforated cylinder 664.
