Description

Technical Field

[0001] The invention relates to the field of plastic processing, and in particular to a device and method for dehydrating and drying chlorinated polyethylene particles. Background Art

[0002] Chlorinated polyethylene particles will contain a certain amount of moisture during the production process. If this moisture is not removed, it will affect the final performance of the product. Through dehydration and drying, the moisture content of the particles can be reduced to a certain level (such as less than 1% or even lower than 0.3%) to meet the requirements of product performance.

[0003] Existing dehydration and drying devices are mainly divided into centrifugal dehydration and fluidized bed dehydration. For centrifugal dehydration, since the centrifuge uses centrifugal force to throw the chlorinated polyethylene particles in piles to the outer edge of the tray, if the density of the piled chlorinated polyethylene particles is too high, it will lead to poor air circulation between the particles, thereby affecting the heat transfer and water evaporation, thereby slowing down the drying speed. In addition, when the chlorinated polyethylene particles are overheated, the chlorinated polyethylene particles may undergo chemical reactions such as thermal decomposition or cross-linking, which will cause changes in their properties.

[0004] However, when using a fluidized bed to dehydrate chlorinated polyethylene particles, the distribution and flow state of the chlorinated polyethylene particles in the drying chamber are uneven, which in turn affects the airflow penetration and heat transfer efficiency, and finally leads to inconsistent drying effects and affects product quality. In addition, the fluidized bed drying process requires precise control of multiple parameters, such as inlet temperature, wind speed, bed height, particle residence time, etc. Slight changes in these parameters may have a significant impact on the drying effect, so the operation is difficult.

[0005] In addition, the material turning method used in existing drying devices is mostly mechanical, that is, using a stirring roller or a stirring paddle to mechanically stir the material. However, for heat-sensitive chlorinated polyethylene particles, excessive temperature and mechanical friction may have an adverse effect on their quality. At the same time, mechanical stirring is prone to dead corners, resulting in incomplete drying of particles in these areas. Summary of the invention

[0022] A method for dehydrating and drying chlorinated polyethylene particles, further comprising the following processing steps:

[0024] S2: After the first arc plate and the second arc plate are assembled, the semi-decay centrifugal mechanism is started. When the semi-decay centrifugal mechanism is started, it drives the drying support plate to perform reciprocating alternating acceleration and deceleration motions;

[0029] Second, the device uses a semi-decay centrifugal mechanism to alternately accelerate and decelerate the drying tray. During the repeated acceleration and deceleration process, the chlorinated polyethylene particles on the turntable will experience more intense mixing and tumbling, which helps to increase the contact area between the chlorinated polyethylene particles and the hot air, eliminate cold spots and hot spots during the drying process, and make the chlorinated polyethylene particles heated more evenly, thereby improving the drying efficiency. The shear force and impact force generated by acceleration and deceleration help to break the agglomeration and agglomeration between the chlorinated polyethylene particles, making the dried chlorinated polyethylene particles looser and more fluid.

[0030] Third: This device uses a jet cylinder to turn the material over. Compared with the mechanical turning methods such as stirring rollers or stirring paddles used in traditional devices, there will be no dead corners when the jet cylinder in this device uses gas. At the same time, the stirring roller and stirring paddle may cause certain mechanical damage to the particles during the turning process, such as scratches, breakage, etc., while the jet cylinder spraying gas is a non-contact turning method that can protect the integrity of the particles to the greatest extent.

[0055] In order to drive the drying support plate 8 to rotate, the following features are also specifically provided:

[0056] The semi-attenuated centrifugal mechanism 12 further includes a first pulley 24, a second pulley 25, a driving gear 26, a speed increasing gear 27, a transfer gear 28 and a driving gear ring 29.

The top plate 30 is coaxially rotatably connected to the lower end of the drying cylinder 6 (refer to Figure 4 ), the top plate 30 is formed with a plurality of leakage holes 31 at equal angles along the circumferential direction. During the drying process of the chlorinated polyethylene particles, the dried water will escape through the leakage holes 31 and the air holes 32 in sequence, thereby improving the dryness inside the device and accelerating the drying speed of the chlorinated polyethylene particles.

[0059] In order to supplement the specific structure of the material turning mechanism 13, the following features are also provided:

[0060] The material turning mechanism 13 also includes an assembly gear 33 and an assembly gear ring 34 (refer to Figure 4 ), the assembly gear 33 is rotationally connected to the top of the drying cylinder 6, the ratchet 35 is rotationally connected to the top of the drying cylinder 6, the assembly gear 33 is coaxially fixed to the outer ring of the ratchet 35, the second gear 17 is coaxially fixed to the inner ring of the ratchet 35, the assembly gear ring 34 is coaxially connected to the top of the drying cylinder 6, and the assembly gear ring 34 is meshed with the assembly gear 33. When the output end of the motor 15 rotates forward, that is, the corresponding fitting gear 19 and the power gear 20 are meshed, the inner and outer rings of the ratchet 35 rotate relative to each other, and the second gear 17 cannot drive the assembly gear 33 to rotate through the ratchet 35.

[0061] In order for the plurality of jet cylinders 14 to spray air onto the first arc plate 9 and the second arc plate 10 when the output end of the motor 15 is reversed, the following features are also specifically provided:

The bearing top plate 36 is coaxially fixedly connected to the lower end of the assembly gear ring 34 (refer to Figure 8 ), the positioning gear ring 38 is coaxially arranged above the bearing bottom plate 37 and is fixedly connected to the drying cylinder 6, the bearing bottom plate 37 is coaxially rotatably connected to the positioning gear ring 38 and is fixedly connected to the bearing top plate 36, a plurality of jet cylinders 14 are fixedly connected to the bearing bottom plate 37, and a plurality of reciprocating screw rods 40 are respectively coaxially slidably arranged with a plurality of jet cylinders 14 (refer to Fig. 9 ), a plurality of sealing gaskets 41 are respectively coaxially fixedly connected to the lower ends of a plurality of reciprocating screw rods 40, the sealing gasket 41 is slidably connected to the inner wall of the jet cylinder 14 along the axial direction of the jet cylinder 14, a plurality of reciprocating gears 39 are respectively coaxially rotatably connected to the plurality of jet cylinders 14, the reciprocating gear 39 is rotatably connected to the bearing base plate 37 and meshes with the positioning gear ring 38, a plurality of reciprocating wire sleeves 42 are respectively coaxially fixedly connected to the plurality of reciprocating gears 39, and the reciprocating screw rod 40 is threadedly connected to the reciprocating wire sleeve 42. When the assembly gear ring 34 rotates, the assembly gear ring 34 will drive the bearing bottom plate 37 to rotate through the bearing top plate 36. After the bearing bottom plate 37 rotates, it will drive a number of reciprocating gears 39 to rotate along the circumferential direction of the drying cylinder 6. When the reciprocating gears 39 move, they will mesh with the positioning gear ring 38. At this time, the reciprocating gears 39 will drive the reciprocating screw rod 40 to move through the reciprocating wire sleeve 42. When the reciprocating screw rod 40 moves, it will drive the corresponding sealing gasket 41 to move. When the sealing gasket 41 moves, it will pump air to the first arc plate 9 and the second arc plate 10, so as to blow the chlorinated polyethylene particles on the first arc plate 9 and the second arc plate 10 back to the center of the drying tray 8.

[0063] In order to facilitate the smooth suction and ejection of the injection cylinder 14, the following features are also specifically provided:

When the sealing gasket 41 moves, the sealing gasket 41 pumps air into the injection cylinder 14 through the air inlet 44, and then pumps air out of the injection cylinder 14 through the air outlet 43. In this process, the first one-way valve 45 and the second one-way valve 46 can ensure that the air flows in one direction, and prevent the chlorinated polyethylene particles from being sucked into the injection cylinder 14 due to the reverse flow of air.

[0065] A method for dehydrating and drying chlorinated polyethylene particles, further comprising the following processing steps:

[0066] S1: The operator first pulls the second arc plate 10 along the long side direction of the guide plate 7, and then puts the wet chlorinated polyethylene particles onto the drying support plate 8;

[0067] S2: After the first arc plate 9 and the second arc plate 10 are assembled, the semi-attenuation centrifugal mechanism 12 is started. When the semi-attenuation centrifugal mechanism 12 is started, it drives the drying support plate 8 to perform reciprocating alternating acceleration and deceleration movements;

[0068] S3: The turning mechanism 13 will spray air toward the drying support plate 8 through the jet cylinder 14, so that the chlorinated polyethylene particles can be fully turned over during the drying process;

[0069] S4: After drying, the operator uses the second arc plate 10 to pull along the long side direction of the guide plate 7, and then takes the dehydrated chlorinated polyethylene particles out of the drying support plate 8.

[0070] The working principle of the device is that when the device is in operation, the operator first pulls the second arc plate 10 along the long side direction of the guide plate 7, then puts the wet chlorinated polyethylene particles on the drying support plate 8, and then starts the motor 15 after assembling the first arc plate 9 and the second arc plate 10.

[0071] The output end of the motor 15 will rotate forward and reverse alternately. When the output end of the motor 15 rotates forward, the power gear 20 will drive the second pulley 25 to rotate through the first pulley 24, and the second pulley 25 will drive the speed-increasing gear 27 to rotate through the driving gear 26. The speed-increasing gear 27 will drive the driving gear ring 29 to rotate through the transfer gear 28, and the driving gear ring 29 will drive the drying support plate 8 fixed thereto to rotate. At this time, the chlorinated polyethylene particles located at the upper end of the drying support plate 8 will be centrifugally dehydrated during the rotation process. When the output end of the motor 15 is reversed, at this time, because the second gear 17 drives the sliding gear 18 to move along the limiting arc groove 23 in the direction away from the power gear 20, the fitting gear 19 and the power gear 20 are separated, and the power gear 20 will slowly slow down. Therefore, the drying support plate 8 will also slowly slow down, and the centrifugal force on the chlorinated polyethylene particles located on the drying support plate 8 will be reduced.

[0072] When the output end of the motor 15 rotates forward, that is, the corresponding fitting gear 19 and the power gear 20 are meshed, the inner and outer rings of the ratchet 35 rotate relative to each other, and the second gear 17 cannot drive the assembly gear 33 to rotate through the ratchet 35. When the output end of the motor 15 rotates reversely, that is, the corresponding fitting gear 19 is not meshed with the power gear 20, the inner and outer rings of the ratchet 35 rotate synchronously, and the second gear 17 drives the assembly gear 33 to rotate through the ratchet 35, and the assembly gear 33 drives the assembly ring gear 34 meshed therewith to rotate. When the assembly ring gear 34 rotates, the jet cylinder 14 will spray air in the direction of the drying tray 8 under the action of the reciprocating gear 39, so that the chlorinated polyethylene particles can be fully turned over during the drying process.

[0073] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
