Description

Technical Field

[0002] In the plastic industry, plastic raw materials need to be melted and then introduced into the injection molding machine to make plastic products. Different plastic products have different performance requirements, and the required plastic raw materials are also different. These plastic raw materials are made by mixing various raw materials together into strips, and then a pelletizer is used to cut these plastic raw materials with strip structures into granules. Before the pelletizer cuts the plastic raw materials with strip structures, the temperature is relatively high, and the plastic raw materials need to be cooled by passing them into cooling water.

[0003] The prior art discloses some invention patents in the field of plastic production equipment technology, among which the invention patent with publication number CN118181573B discloses a plastic granulator, including an extrusion barrel, the end of which is connected to an extrusion cutting device, and a buffer cover, a mold barrel connected to the buffer cover, and an extrusion column and an extrusion column arranged on both sides of the mold barrel, so as to realize quantitative extraction of plastic melt, and then use the extrusion column linked with the extrusion column to extrude the plastic melt, so that the texture of the formed plastic strip is compact, which is convenient for subsequent cutting. In addition, when cutting, the extrusion column and the extrusion column are clamped on both sides of the plastic strip, so that the extruded plastic strip is in a horizontal state when cutting, which improves the plastic The stability of the material strip during cutting is achieved through quantitative, extrusion and horizontal clamping and traction, so that the molded plastic particles have a tight texture and a smooth cut, thereby improving the molding quality of the plastic particles. This technical solution still has some shortcomings in the process of application. The plastic particles in the stirred state are dried at high temperature. Although this method can achieve the drying effect, the plastic particles have a certain adsorption capacity due to their high moisture content, and are easy to accumulate. Even during the stirring process, the plastic particles cannot be separated and fully contacted with the hot air, which is not convenient for the circulation of hot air and has a poor drying effect. It is not only easy to cause local heat concentration, resulting in melting and damage of the plastic particles, but also high energy consumption and long time consumption.

The other ends of the multiple shunt pipes are connected to the same multi-phase joint with a telescopic function, and the multi-phase joint is connected to the steam exhaust pipe through a pipeline, and the strip material is water-cooled in the water-cooled box to generate steam.

[0014] A mixing extrusion granulation process, using the novel mixing extrusion granulation equipment, comprises the following steps: S1: Various raw materials are put into the mixer for mixing. The mixed materials are sent to the screw extruder through the conveying pipe. The materials are processed by the screw extruder to form strip materials. The strip materials are pulled through the water cooling box and then fed into the granulator for granulation; S2: When the strip material is transported in the water-cooled box, it encounters water and generates steam. The motor is controlled to run. The motor drives the exhaust fan to rotate rapidly through the motor shaft. Driven by the exhaust fan, the steam generated in the water-cooled box enters the steam treatment hood and is then injected into the multiphase joint through the steam discharge pipe. When the steam flows from the water-cooled box to the steam treatment hood, the wire mesh separator will capture water droplets in the steam. S3: When the motor shaft drives the exhaust fan to rotate, it also drives the multiple spherical hoop heads to make circular motion through the linkage disk, and the multiple spherical hoop heads drive the multiple spherical balls to roll in the corrugated groove of the corrugated disk. When the multiple spherical balls gradually roll out from the corrugated groove to the disk surface of the corrugated disk, since the heights of the multiple spherical balls remain unchanged, the multiple spherical balls will generate a downward thrust on the corrugated disk. Under the action of the downward thrust, the wire mesh separator slides in the first slide groove through the first slider, and causes the support spring to undergo elastic deformation. When the multiple spherical balls gradually roll from the disk surface of the corrugated disk into the multiple corrugated grooves, the downward pressure exerted by the multiple spherical balls on the corrugated disk gradually weakens, and the support spring gradually recovers. During the recovery process, the support spring drives the wire mesh separator to move upward through the first slider. According to this rule, the wire mesh separator will be driven to perform high-frequency reciprocating lifting and lowering motion in the steam treatment hood; S4: Before the strip material is fed into the granulator through water cooling, it also passes through a dehydration box. During the high-frequency vibration process, the wire mesh separator also drives the ends of the two driving rods to move synchronously through two combined rods. The other end of the driving rod pushes or pulls one end of the transmission plate through the adapter shaft and rotates with the other end of the transmission plate. The transmission plate slides on the second slider through the second slide groove. During this process, on the one hand, the second slider rotates around one end of the bridge rod, and on the other hand, the second slider makes a circular motion along the axis of the vibration shaft through the other end of the bridge rod. The transmission plate drives multiple teeth and gears to move relative to each other. Since the fillets of the teeth on the two transmission parts are designed in opposite directions, the two gears can be continuously driven to rotate rapidly in one direction, and the two gears drive multiple eccentric wheels on the vibration shaft to rotate rapidly. Vibration is generated during the rapid rotation of the eccentric wheel, and acts on the bottom of the dehydration plate through the adapter seat. Therefore, the water stains remaining on the surface of the strip material will fall off during the process of flowing through the dehydration plate; S5: The dehydrated steam enters the multiphase joint through the steam discharge pipe and the pipeline, and flows into multiple branch pipes through the multiphase joint. The steam flowing into the branch pipe is ejected through multiple nozzles connected to the surface of the branch pipe. The steam drives the blade wheel to rotate during the flow inside the nozzle, and the rotation directions of the two adjacent blade wheels in the same row are opposite.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, the steam drives the blade wheel to rotate during the flow inside the nozzle, and the rotation directions of two adjacent blade wheels in the same row are opposite to each other. The steam is blown out through each nozzle, and the airflow blown out by the steam blows the plastic particles up to a certain height. The steam blows the material particles up and carries the plastic particles for transmission under the action of the airflow attraction. During the movement, rows of plastic particles flow into adjacent vortices under the action of centrifugal force. The wind blows the plastic particles to fly quickly and dry them in the air. On the one hand, it is convenient to blow away the bonded plastic particles. On the other hand, the wind speed and temperature are uniform, which avoids damage to the plastic particles or uneven drying. The steam generated by the cooling of the strip material is used to dry the plastic particles, which has a certain energy-saving and emission reduction effect. The distance between two adjacent nozzles in a single row is adjusted according to the particle size and quality of the plastic particles, which is conducive to evenly dispersing the plastic particles and avoiding damage to the plastic particles easily caused by the drying process.

[0016] 2. In the present invention, the eccentric wheel generates vibration during rapid rotation and acts on the bottom of the dehydration plate through the adapter seat. Therefore, the water stains remaining on the surface of the strip material will fall off when the strip material flows through the dehydration plate, thereby effectively removing most of the moisture on the surface of the strip material, removing the water droplets attached to the strip material, reducing the subsequent drying time of the strip material, and avoiding the impact of long-term processing on the strip material.

[0017] 3. In the present invention, the wire mesh separator is driven to perform high-frequency reciprocating lifting and lowering motion in the steam treatment hood, so that the high-frequency vibration of the wire mesh separator can cause some of the captured water droplets to fall off, thereby ensuring the effective duration of the wire mesh separator during operation.

[0028] A novel mixing extrusion granulation process, using the novel mixing extrusion granulation equipment, comprises the following steps: Various raw materials are put into the mixer 1 for mixing. The mixed materials are sent to the screw extruder 2 through the conveying pipe 3. The materials are processed by the screw extruder 2 to form strip materials. Generally, the strip materials are pulled manually through the water cooling box 4 and the limit guide wheel ( Figure 3 As shown) the strip material continuously passes through the water cooling box 4 and is then fed into the granulator 7 for granulation; When the strip material is transported in the water-cooling box 4, it encounters water and generates steam. The motor 5065 is controlled to operate. The motor 5065 drives the exhaust fan 508 to rotate rapidly through the motor shaft. The steam generated in the water-cooling box 4 enters the steam treatment hood 501 under the guidance of the exhaust fan 508, and then is injected into the multi-phase joint 806 through the steam discharge pipe 507 through the pipeline. When the steam flows from the water-cooling box 4 to the steam treatment hood 501, the wire mesh separator 502 will capture water droplets in the steam. In the process of driving the exhaust fan 508 to rotate, the motor shaft will also drive the multiple spherical hoop heads 5062 to make circular motion through the linkage disk 5064, and the multiple spherical hoop heads 5062 will drive the multiple spherical balls 5063 to roll in the corrugated grooves of the corrugated disk 5061. In the process of the multiple spherical balls 5063 gradually rolling out from the corrugated grooves to the surface of the corrugated disk 5061, since the heights of the multiple spherical balls 5063 remain unchanged, the multiple spherical balls 5063 will generate a downward thrust on the corrugated disk 5061, and under the action of the downward thrust, the wire mesh separator 502 passes through the corrugated grooves. The first slider 504 slides in the first slide groove 503, and the support spring 505 is elastically deformed. When the multiple spherical balls 5063 gradually roll from the surface of the corrugated disk 5061 into the multiple corrugated grooves, the downward pressure of the multiple spherical balls 5063 on the corrugated disk 5061 gradually weakens, and the support spring 505 gradually recovers. During the recovery process, the support spring 505 drives the wire mesh separator to move upward through the first slider 504. According to this rule, the wire mesh separator 502 will be driven to perform high-frequency reciprocating lifting and lowering motion in the steam treatment cover 501; The long strip material passes through the dehydration box 601 before being fed into the granulator 7 after water cooling. The wire mesh separator 502 also drives the ends of the two driving rods 614 to move synchronously through the two combined rods 612 during the high-frequency vibration. The other end of the driving rod 614 pushes or pulls one end of the transmission plate 6071 through the adapter shaft 613, and rotates with one end of the transmission plate 6071. The transmission plate 6071 slides on the second slider 608 through the second slide groove 609. In this process, on the one hand, the second slider 608 rotates around one end of the bridge rod 610, and on the other hand, the second slider 608 rotates around one end of the bridge rod 610. The other end makes a circular motion along the axis of the vibration shaft 604, and the transmission plate 6071 drives the multiple teeth 6072 to move relative to the gear 606. Since the rounded corners of the teeth 6072 on the two transmission members 607 are designed in opposite directions, the two gears 606 can be continuously driven to rotate rapidly in one direction, and the two gears 606 drive the multiple eccentric wheels 605 on the vibration shaft 604 to rotate rapidly. The eccentric wheels 605 generate vibrations during the rapid rotation, and act on the bottom of the dewatering plate 602 through the adapter 603, so that the water stains remaining on the surface of the strip material will fall off during the process of flowing through the dewatering plate 602; After entering the multi-phase joint 806, the dehydrated steam flows into multiple branch pipes 803 through the multi-phase joint 806, and the steam flowing into the branch pipe 803 is ejected through multiple nozzles 804 connected to the surface thereof. During the flow of steam inside the nozzle 804, the impeller 805 is driven to rotate, and the rotation directions of two adjacent impellers 805 in the same row are opposite to each other.

9. A mixing extrusion granulation process, characterized in that: The use of the novel mixing extrusion granulation equipment according to claim 8 comprises the following steps: S1: Various raw materials are put into a mixer (1) for mixing. The mixed materials are sent to a screw extruder (2) through a conveying pipe (3). The materials are processed by the screw extruder (2) to form strip materials. The strip materials are pulled through a water cooling box (4) and then fed into a granulator (7) for granulation. S2: When the strip material is transported in the water-cooling box (4), it encounters water and generates steam. The motor (5065) is controlled to operate. The motor (5065) drives the exhaust fan (508) to rotate rapidly via the motor shaft. The steam generated in the water-cooling box (4) enters the steam treatment hood (501) under the guidance of the exhaust fan (508), and is then injected into the multiphase joint (806) through the steam discharge pipe (507). When the steam flows from the water-cooling box (4) to the steam treatment hood (501), the wire mesh separator (502) will capture water droplets in the steam. S3: When the motor shaft drives the exhaust fan (508) to rotate, it also drives the multiple spherical hoop heads (5062) to make circular motion through the linkage disk (5064), and the multiple spherical hoop heads (5062) drive the multiple spherical balls (5063) to roll in the corrugated grooves of the corrugated disk (5061). When the multiple spherical balls (5063) gradually roll out from the corrugated grooves onto the surface of the corrugated disk (5061), since the heights of the multiple spherical balls (5063) remain unchanged, the multiple spherical balls (5063) will generate a downward thrust on the corrugated disk (5061). Under the action of the downward thrust, the wire mesh separator (502) passes through The first slider (504) slides in the first slide groove (503) and causes the support spring (505) to undergo elastic deformation. When the plurality of spherical balls (5063) gradually roll from the surface of the corrugated disk (5061) into the plurality of corrugated grooves, the downward pressure exerted by the plurality of spherical balls (5063) on the corrugated disk (5061) gradually weakens, and the support spring (505) gradually recovers. During the recovery process, the support spring (505) drives the wire mesh separator (502) to move upward through the first slider (504). This rule drives the wire mesh separator (502) to perform high-frequency reciprocating lifting and lowering motion in the steam treatment hood (501); S4: The strip material passes through a dehydration box (601) before being fed into the granulator (7) after being cooled by water. During the high-frequency vibration process, the wire mesh separator (502) drives the ends of the two driving rods (614) to move synchronously through the two combined rods (612). The other end of the driving rod (614) pushes or pulls one end of the transmission plate (6071) through the adapter shaft (613) and rotates with the one end of the transmission plate (6071). The transmission plate (6071) slides on the second slider (608) through the second slide groove (609). During this process, on the one hand, the second slider (608) rotates around one end of the bridge rod (610). On the other hand, the second slider (608) rotates through the bridge rod (610). 10) makes a circular motion along the axis of the vibration shaft (604), and the transmission plate (6071) drives the plurality of teeth (6072) to move relative to the gear (606). Since the rounded corners of the teeth (6072) on the two transmission members (607) are designed in opposite directions, the two gears (606) can be continuously driven to rotate rapidly in one direction, and the two gears (606) drive the plurality of eccentric wheels (605) on the vibration shaft (604) to rotate rapidly. The eccentric wheels (605) generate vibrations during the rapid rotation, and act on the bottom of the dewatering plate (602) through the adapter seat (603), so that the water stains remaining on the surface of the strip material will fall off during the process of flowing through the dewatering plate (602); S5: The dehydrated steam enters the multiphase joint (806) through the steam discharge pipe (507) and the multiphase joint (806), and flows into the plurality of branch pipes (803) respectively. The steam flowing into the branch pipe (803) is ejected through the plurality of nozzles (804) connected to the surface of the branch pipe. The steam drives the blade wheel (805) to rotate during the flow inside the nozzle (804), and the rotation directions of the two adjacent blade wheels (805) in the same row are opposite.
