Description

Technical Field

[0001] This utility model relates to the technical field of chemical fiber production equipment, specifically a surface deburring device for the production of recycled polyester for chemical fibers. Background Technology

[0002] In the chemical fiber industry, recycled polyester has become an important development direction for polyester material production due to its advantages such as resource recycling and reduced production costs. However, during the production process, recycled polyester granules inevitably develop defects such as burrs and sharp edges on their surface due to factors such as processing technology and raw material characteristics. These surface defects not only affect the appearance quality of the recycled polyester granules, but may also lead to problems such as fiber breakage and equipment wear in subsequent processing stages such as spinning and weaving, thereby reducing the quality of chemical fiber products and production efficiency.

[0003] A search revealed that patent publication number CN217394648U discloses a rapid grinding device for processing recycled modified plastic granules. The device includes a base, a first collection bucket, and a second collection bucket. Two fixing blocks are fixedly connected to the upper surface of the base, and a connecting block is fixed to the upper surface of both fixing blocks. The advantages are: when polishing sand and plastic granules are poured into the second collection bucket, the motor is turned on to rotate the rod and stirring blades, and the polishing sand grinds the plastic granules. After grinding, the hydraulic rod is activated to move downwards, separating the top block of the first collection bucket from the filter hole of the second collection bucket. The motor is then turned on again to drive the rotating rod and stirring blades to stir the mixture. The polishing sand falls through the filter hole into the first collection bucket, separating the polishing sand from the plastic granules and grinding the burrs on the outer wall of the plastic granules, preventing the burrs from affecting normal processing. Simultaneously, the polishing sand can be directly separated from the granules without removing the mixture, thus accelerating the grinding speed.

[0004] Currently, most commercially available deburring equipment for recycled polyester granules employs mechanical grinding or chemical treatment. Mechanical grinding suffers from uneven deburring results and can easily damage the granules themselves; chemical treatment methods face drawbacks such as environmental pollution, high processing costs, and potential alteration of the granules' chemical properties. While some deburring equipment using a roller structure improves processing efficiency to some extent, it still has many shortcomings in practical applications. The heat generated during the deburring process causes the temperature of the recycled polyester granules to rise. Since recycled polyester has a low glass transition temperature, excessively high temperatures can easily cause granule deformation, severely affecting product quality. Therefore, a surface deburring device for the production of recycled polyester for chemical fibers is designed. Utility Model Content

[0005] In view of the defects or deficiencies of surface deburring equipment used in the production of recycled polyester for chemical fibers, the purpose of this utility model is to provide a surface deburring equipment for the production of recycled polyester for chemical fibers, which effectively avoids problems such as deformation and adhesion of recycled polyester particles due to excessive temperature during the deburring process, and ensures that the quality of recycled polyester particles is not affected.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a surface deburring device for the production of recycled polyester for chemical fibers, including a mounting frame. A housing is mounted on the top of the mounting frame. A deburring assembly for deburring recycled polyester particles is provided on the housing. A deburring roller is provided on the deburring assembly and is located inside the housing. Connecting shafts are installed on both end walls of the deburring roller. The other ends of the two connecting shafts pass through bearings on the outer walls of both sides of the housing and extend to the outside. A driven pulley is installed on the other end of one of the connecting shafts.

[0008] The housing is provided with a liquid circulation assembly for circulating the liquid inside the housing and rinsing the deburring roller. The housing is also provided with a cooling assembly for air cooling the liquid flowing inside the housing. A geared motor for driving the deburring assembly is installed on one side of the top of the mounting bracket.

[0009] Preferably, a drive pulley is mounted on the output shaft of the geared motor, and the drive pulley is connected to the driven pulley via a transmission belt.

[0010] Preferably, the liquid circulation flow assembly is provided with a flow divider plate, which is installed above the rear end wall inside the housing. The liquid outlet end of the flow divider plate is provided with a nozzle, and the liquid inlet end of the flow divider plate extends through the rear end wall of the housing to the outside and is connected to the delivery pipeline through a pipe joint.

[0011] Preferably, the other end of the conveying pipe is connected to the liquid outlet end on the pump body through a pipe joint, the liquid inlet end on the pump body is connected to the liquid outlet pipe through a pipe joint, and the liquid outlet pipe is located below the outer wall on one side of the housing, and the pump body is installed on the other side of the top of the mounting bracket.

[0012] Preferably, the cooling component is provided with a housing, which is located above the rear end of the outer wall on the other side of the housing. The housing is provided with an installation plate inside, and a fan is installed on one side of the outer wall of the installation plate. A vent is provided on one side of the fan and is located on the outer wall of the installation plate.

[0013] Preferably, an air inlet slot is provided on one side of the outer wall of the box, and ventilation holes are provided on the other side of the outer wall of the box and the other side of the outer wall of the shell. The ventilation holes on the box and the ventilation holes on the shell are connected. A sealing door is provided on the front wall of the box.

[0014] Preferably, an exhaust trough is provided at the rear end of one side of the outer wall of the housing, and staggered baffles are provided at the front and rear ends of the exhaust trough. Sealing doors are provided at the top, front wall and bottom of the housing. The deburring roller is a hollow hexagonal prism, in which filter holes are provided on five of the six rectangular sides and a sealing door is provided on one rectangular side.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0016] 1. In this utility model, through a series of coordinated structural arrangements, when the operator performs deburring on recycled rectangular granules, the operator pours the recycled polyester granules and grinding media into the deburring drum. After pouring a certain amount of water into the housing, the operator starts the equipment. The pump on the liquid circulation component starts and transports the liquid inside the housing to the nozzle. The nozzle sprays the liquid onto the deburring drum. The liquid flows from the filter holes on the outer wall of the deburring drum into the interior of the deburring drum and then flows from the filter holes on the deburring drum back into the housing. The heat generated by the friction between the grinding media and the recycled polyester granules is transferred to the liquid. During the liquid circulation process, the fan on the cooling component blows external air onto the liquid sprayed from the nozzle, and the air inside the housing is discharged to the outside through the exhaust vent. The airflow cools the liquid, effectively preventing the recycled polyester granules from deforming or sticking due to excessive temperature during the deburring process, thus ensuring that the quality of the recycled polyester granules is not affected.

[0017] 2. In this utility model, through a series of structural arrangements, the nozzle sprays liquid onto the outer wall of the deburring roller, thereby rinsing the filter holes on the outer wall of the deburring roller. This avoids the filter holes on the outer wall of the deburring roller becoming clogged, preventing the liquid from flowing into the interior of the deburring roller and causing problems such as excessively high temperature of the recycled polyester particles, deformation, and adhesion. This further ensures that the quality of the recycled polyester particles is not affected. Attached Figure Description

[0037] A drive pulley is installed on the output shaft of the geared motor 200. The drive pulley is connected to the driven pulley 330 through a transmission belt. When the geared motor 200 starts, it drives the drive pulley to rotate. When the drive pulley rotates, it drives the driven pulley 330 to rotate through the transmission belt. When the driven pulley 330 rotates, it drives the deburring roller 310 to rotate.

[0038] A flow divider plate 420 is provided on the liquid circulation flow assembly 400. The flow divider plate 420 is installed above the rear end wall inside the housing 100. A nozzle 410 is provided at the liquid outlet end on the front end wall of the flow divider plate 420. The liquid inlet end on the rear end wall of the flow divider plate 420 extends through the rear end wall of the housing 100 to the outside and is connected to the delivery pipe 430 through a pipe joint.

[0039] The other end of the delivery pipe 430 is connected to the liquid outlet on the pump body 440 through a pipe fitting. The liquid inlet on the pump body 440 is connected to the liquid outlet pipe through a pipe fitting, and the liquid outlet pipe is located below the outer wall on one side of the housing 100. The pump body 440 is installed on the other side of the top of the mounting bracket 500. When the pump body 440 is started, it will deliver the liquid inside the housing 100 to the inside of the diverter plate 420 through the delivery pipe 430. The liquid inside the diverter plate 420 will be sprayed out from the nozzle 410.

[0040] The cooling component 600 is provided with a housing 610, and the housing 610 is located above the rear end of the outer wall on the other side of the housing 100. The housing 610 is provided with a mounting plate 630. A fan 620 is installed on one side of the outer wall of the mounting plate 630. A vent is provided on one side of the fan 620 and the vent is located on the outer wall of the mounting plate 630.

[0041] An air inlet slot is provided on one side of the outer wall of the enclosure 610, and ventilation holes are provided on the other side of the outer wall of the enclosure 610 and the other side of the outer wall of the shell 100. The ventilation holes on the enclosure 610 are connected to the ventilation holes on the shell 100, and a sealing door is provided on the front wall of the enclosure 610.

Then, pour a certain amount of water into the housing 100 and start the equipment. The pump 440 on the liquid circulation component 400 will start, transporting the liquid inside the housing 100 to the nozzle 410. The nozzle 410 sprays the liquid onto the deburring roller 310. The liquid flows from the filter holes on the outer wall of the deburring roller 310 into the interior of the deburring roller 310 and then back into the housing 100. The heat generated by the friction between the grinding media and the recycled polyester granules is transferred to the liquid. The liquid circulation component 400, during the liquid circulation process, cools the liquid. When the fan 620 on component 600 starts, it blows external air toward the liquid sprayed by nozzle 410, and the air inside the housing 100 is discharged to the outside through the exhaust duct 110. During the air flow, the liquid is cooled, which effectively prevents the recycled polyester particles from deforming or sticking due to excessive temperature during the deburring process, ensuring that the quality of the recycled polyester particles is not affected. The nozzle 410 sprays the liquid toward the outer wall of the deburring roller 310, which washes the filter holes on the outer wall of the deburring roller 310, preventing the filter holes on the outer wall of the deburring roller 310 from becoming blocked, which would prevent the liquid from flowing into the deburring roller 310 and cause the recycled polyester particles to deform or stick due to excessive temperature, further ensuring that the quality of the recycled polyester particles is not affected.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
