Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal equipment, in particular to an auxiliary dust removal device for granulating polyphenylene sulfide composite materials. Background Art

[0002] Polyphenylene sulfide (PPS) composites are made by adding fillers such as fibers and mineral powder to PPS, imparting new functionalities. These composites not only retain the inherent high heat resistance, strength, and excellent chemical stability of PPS, but also impart a series of unique new features, such as enhanced rigidity, toughness, thermal conductivity, electrical conductivity, and self-lubrication. These materials perfectly meet the market demand for diversified and customized high-performance materials and are widely used in automotive engine peripherals, headlights, TMM thermal management systems, hydrogen fuel cell humidifiers, lithium battery gaskets, battery boxes, microwave ovens, electric ovens, water dispensers, and coffee machines. During the processing of PPS, pelletizing is necessary for convenient subsequent use and transportation, necessitating the use of a pelletizer. In existing technologies, pelletizers discharge the pellets directly from the discharge port without performing surface dust removal on the PPS composites. This can result in floating impurities and dust in the material, which is difficult to remove and pollutes the working environment. Utility Model Content

[0040] like Figure 1-6 As shown, an auxiliary dust removal device for granulating polyphenylene sulfide composite materials includes a dust removal shell 1, which is connected to the discharge pipe 2 of the granulator;

[0041] A filter 3 is slidingly provided in the dust removal housing 1. Four sets of springs 4 are symmetrically provided at both ends of the bottom of the dust removal housing 1. The other ends of the springs 4 are fixedly connected to the bottom of the filter 3. A dust collector 5 is connected to the side of the dust removal housing 1. The connection between the dust collector 5 and the dust removal housing 1 is located below the filter 3.

[0042] A stirring assembly 6 is provided in the dust removal housing 1. The stirring assembly 6 includes a first rotating shaft 63. A plurality of first stirring rods 61 and second stirring rods 62 are provided on the first rotating shaft 63. The first stirring rods 61 and the second stirring rods 62 are symmetrically arranged along the circumference of the first rotating shaft 63. The axial length of the first stirring rod 61 is smaller than the axial length of the second stirring rod 62. When the second stirring rod 62 rotates downward, it pushes the filter 3 to slide downward along the inner wall of the dust removal housing 1.

[0043] A linkage assembly 7 is provided in the dust removal housing 1 for driving the stirring assembly 6. One end of the first rotating shaft 63 is connected to the linkage assembly 7, and the other end is fixed to the inner wall of the dust removal housing 1 through a bearing;

[0044] A discharge port 11 is provided on the side of the dust removal housing 1 , and the discharge port 11 is arranged above the filter screen 3 .

[0045] The polyphenylene sulfide composite material particles are fed into the dust removal shell 1 from the discharge pipe 2 of the granulator, and the vacuum cleaner 5 is started. The particles fall onto the filter 3, and the dust is adsorbed by the filter 3 and sucked into the vacuum cleaner 5 from the bottom of the filter 3. The linkage component 7 drives the stirring component 6 to rotate to stir the particles. During the stirring process, the dust will fall onto the filter 3. When the second stirring rod 62 rotates to the bottom, it generates a downward thrust on the filter 3. The filter 3 slides downward along the inner wall of the dust removal shell 1, and generates a downward compression force on the spring 4 at the bottom. When the second stirring rod 62 is out of contact with the filter, the spring 4 at the bottom generates an upward elastic force on the filter 3 due to the elastic action. The filter 3 vibrates up and down to shake off the dust to the bottom, and finally is sucked into the vacuum cleaner 5, thereby improving the dust removal effect.

[0046] Preferably, the end of the second stirring rod 62 is hemispherical, which makes it easier to generate a downward thrust on the filter screen 3 when it is rotated downward.

[0047] Preferably, a limiting groove 12 is provided on the inner wall of the dust removal shell 1, and the filter 3 is slidably connected to the limiting groove 12. The limiting groove 12 can limit the amplitude of the up and down vibration of the filter 3 to avoid the vibration amplitude being too large to be difficult to control.

[0048] Preferably, a telescopic column 41 is provided in the spring 4, and the two ends of the telescopic column 41 are fixedly connected to the bottom of the filter 3 and the bottom of the dust removal shell 1 respectively, which can provide better support for the filter 3 and protect the spring 4, avoiding misalignment and compression due to unstable force when the spring 4 is compressed.

[0049] Preferably, the linkage assembly 7 includes a second rotating shaft 71, the two ends of the second rotating shaft 71 are respectively rotatably connected to the inner top and bottom of the dust removal housing 1, a motor 72 is provided on the top of the dust removal housing 1, and the output end of the motor 72 extends into the dust removal housing 1 and is connected to the second rotating shaft 71; a fixing seat 73 is provided on the side of the second rotating shaft 71, and the fixing seat 73 is fixedly connected to the top of the dust removal housing 1 through a fixing rod 74;

[0050] A first bevel gear 75 is fixedly provided on the second rotating shaft 71 , and the first bevel gear 75 is arranged in the fixed seat 73 . A second bevel gear 76 is rotatably provided on the fixed seat 73 . The first bevel gear 75 and the second bevel gear 76 are meshed and connected. One end of the first rotating shaft 63 extends into the fixed seat and is connected to the second bevel gear 76 .

[0051] Preferably, two second bevel gears 76 are provided, which are symmetrically arranged with the first bevel gear 75 as the center; and two groups of stirring components 6 are provided, which are symmetrically arranged with the fixing seat 73 as the center.

[0052] The motor 72 drives the second rotating shaft 71 to rotate, and the first bevel gear 75 fixedly connected to the second rotating shaft 71 rotates, which drives the two second bevel gears 76 to rotate, and drives the two sets of stirring components 6 to rotate to stir the particles and apply thrust to the filter 3 to make it vibrate, thereby accelerating the dust removal of the particles.

[0053] Preferably, a sliding sleeve 77 is provided on the second rotating shaft 71, and the sliding sleeve 77 rotates synchronously with the second rotating shaft 71. The sliding sleeve 77 is rotatably connected to the filter screen 3 through a bearing. Brushes 31 are symmetrically provided on the side of the sliding sleeve 77. The two brushes 31 are respectively provided on the top and bottom of the filter screen 3 to clean the upper and lower end faces of the filter screen 3.

[0054] Preferably, a plurality of strips 78 are provided on the side of the second rotating shaft 71 , and the sliding sleeve 77 is engaged with the strips 78 and can slide up and down along the strips 78 .

[0055] Preferably, the two brushes 31 are arranged alternately.

[0056] As the second rotating shaft 71 rotates, the sliding sleeve 77 is driven to rotate due to the locking effect between the bar 78 and the inside of the sliding sleeve 77, so that the brush 31 sweeps off the dust on the upper and lower ends of the filter 3 to prevent the filter 31 from being blocked. When the filter 31 is squeezed and vibrated, the sliding sleeve 77 slides up and down along the bar 78 and rotates with the second rotating shaft 71.

[0057] Preferably, a baffle 22 is provided at one end of the discharge pipe 2 close to the dust removal shell 1 through a third rotating shaft 21, and one end of the third rotating shaft 21 extends out of the discharge pipe 2 and is connected to a torque 23. The baffle 22 is driven to rotate by rotating the torque 23, thereby controlling the channel size of the discharge pipe 2 and further controlling the speed at which particles enter the dust removal shell 1.

[0058] The working principle of the present invention is as follows: the inclination angle of the baffle 22 is adjusted to control the speed at which the polyphenylene sulfide composite material particles are fed from the discharge pipe 2 of the granulator to the dust removal housing 1, the dust collector 5 and the motor are started, the particles fall onto the filter screen 3, the motor 72 drives the second rotating shaft 71 to rotate, the first bevel gear 75 fixedly connected to the second rotating shaft 71 rotates, drives the two second bevel gears 76 to rotate, drives the two sets of stirring components 6 to rotate, and stirs the particles. During the stirring process, the dust will fall onto the filter screen 3, and at the same time, the second rotating shaft 71 rotates to drive the sliding sleeve 77 to rotate, so that the brush 31 respectively rotates to the second rotating shaft 71. The dust at the upper and lower ends of the filter 3 is swept away to prevent the filter 31 from being blocked. When the second stirring rod 62 rotates to the downward direction, a downward thrust is generated on the filter 3, and the filter 3 slides downward along the inner wall of the dust removal shell 1, generating a downward compression force on the spring 4 at the bottom. When the second stirring rod 62 is out of contact with the filter, the spring 4 at the bottom generates an upward elastic force on the filter 3 due to the elastic action. The amplitude of the up and down vibration of the filter 3 can be limited by the limiting groove 12 to avoid the vibration amplitude being too large. The up and down vibration of the filter 3 can shake off the dust to the bottom, and finally be sucked into the vacuum cleaner 5, thereby improving the dust removal effect.

[0059] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
