Description

Technical Field

[0001] The utility model relates to the technical field of plastic mixing and stirring, in particular to a noise reduction and cooling device for plastic particles. Background Art

[0002] Plastic granules refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, and polyurethane. Engineering plastics include nylon, polytetrafluoroethylene, polyoxymethylene, and polycarbonate silicone.

[0003] When using plastic pellets, a stirring device is usually required to mix and stir multiple plastic pellets. After searching, a Chinese patent authorization announcement number CN218452096U, with an announcement date of February 7, 2023, proposed a plastic pellet mixer with a noise reduction function. The article proposes "by covering the outer tube outside the inner tube, a first sound-absorbing cotton is arranged inside the outer tube, and the sound-absorbing sponge can be placed inside the storage cavity, thereby absorbing the noise generated by the mixing inside the inner tube, and the connecting hole connects the inner tube and the outer tube, so that the noise can be transmitted to the first sound-absorbing cotton and the sound-absorbing sponge more quickly, and the noise reduction effect is better. The sound insulation component cover is provided on the feed port to achieve sound insulation and noise reduction of the entire mixer, avoiding the noise causing discomfort to the surrounding personnel."

[0004] However, in the above scheme, the plastic particles are stirred and mixed by a stirring rod. When the stirring rod rotates inside the outer cylinder to drive the plastic particles to mix, the plastic particles will continuously contact and rub against the inner wall of the outer cylinder, thereby increasing the source of noise generated by the mixer during use, causing the noise of the mixer to become louder during use.

[0005] For this purpose, a plastic particle noise reduction cooling device is specially proposed. Utility Model Content

[0011] Preferably, a filter is installed inside the exhaust pipe by bolts, and an electric exhaust fan is installed on the top of the exhaust pipe.

[0012] Compared with the existing technology, the utility model provides a plastic particle noise reduction cooling device with the following beneficial effects:

[0013] The plastic particles inside the mixing tank body will be brought into the interior of the soundproof conveying pipe through the rotation of the feeding auger. As the feeding auger rotates, the plastic particles at the bottom will be transported to the top and then scattered from the top of the soundproof conveying pipe and fall back into the interior of the mixing tank body, thereby completing the mixing of multiple plastic particles.

In this way, the contact and friction between the plastic particles and the stirring device during the stirring process can be avoided, so that the noise caused by the contact friction between the plastic particles and the inner wall of the mixing tank body will not be generated, ensuring sufficient stirring while reducing the noise level.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Three support frames 10 are welded at equal distances on the outside of the bottom of the soundproof conveying pipe 3. The bottoms of the three support frames 10 are welded to the bottom end of the inner wall of the mixing tank body 1 respectively. A feeding screw 5 is installed inside the mixing tank body 1 through a rotating shaft. The feeding screw 5 is located inside the soundproof conveying pipe 3. The top of the mixing tank body 1 is fixed with a motor 8 by bolts. A heat dissipation component 7 is welded on one side of the top of the mixing tank body 1. The heat dissipation component 7 is connected to the inside of the mixing tank body 1. An air inlet is welded on one side of the top of the mixing tank body 1. Filter tube 9, the outer fixed sleeve of the mixing tank body 1 is provided with an external sound insulation cotton sleeve 2, a feed pipe 14 is welded on one side of the top of the mixing tank body 1, and the feed pipe 14 is connected to the interior of the mixing tank body 1, and a plurality of support rods 6 are welded on the outside of the feeding auger 5, and a buffering sound insulation sleeve 4 is installed at one end of the plurality of support rods 6, and the inner wall of the buffering sound insulation sleeve 4 is fixed with buffering sound-absorbing cotton, the top and bottom ends of the sound insulation conveying pipe 3 are respectively open, and the output end of the motor 8 extends into the interior of the mixing tank body 1 and is fixedly connected to the top of the feeding auger 5.

[0021] Specifically, such as Figure 1 and Figure 2As shown, since the bottom ends of the three support frames 10 welded to the bottom of the outer side of the soundproof conveying pipe 3 are respectively welded to the bottom end of the inner wall of the mixing tank body 1, and a feeding screw dragon 5 is installed inside the soundproof conveying pipe 3, when the plastic particles enter the inside of the mixing tank body 1, the rotation of the output end of the motor 8 can drive the feeding screw dragon 5 to rotate inside the soundproof conveying pipe 3. Since the bottom end of the feeding screw dragon 5 extends out of the inside of the soundproof conveying pipe 3, the plastic particles will be brought into the inside of the soundproof conveying pipe 3 through the rotation of the feeding screw dragon 5. As the feeding screw dragon 5 rotates, the plastic particles at the bottom will be The particles are transported to the top and then scattered from the top of the soundproof conveying pipe 3 and fall back into the interior of the mixing tank body 1, thereby completing the mixing of multiple plastic particles. Since the outer side of the soundproof conveying pipe 3 is provided with sound-absorbing cotton, the noise generated by the plastic particles in the transportation process inside the soundproof conveying pipe 3 can be absorbed, thereby reducing the noise level. Since the outer side of the feeding auger 5 is fixed with a buffer sound insulation sleeve 4 through the support rod 6, the buffer sound insulation sleeve 4 can prevent the fallen plastic particles from directly contacting the inner wall of the mixing tank body 1, thereby preventing the plastic particles from falling and contacting the mixing tank body 1. The noise generated by the contact with the inner wall of the tank body 1, the plastic particles that emerge from the top of the sound insulation conveying pipe 3 and fall again will fall on the inner wall of the buffer sound insulation sleeve 4. Since the inner wall of the buffer sound insulation sleeve 4 is installed with a buffer sound-absorbing cotton, the plastic particles falling on the inner wall of the buffer sound insulation sleeve 4 can be buffered and the noise generated by the plastic particles falling can be absorbed at the same time. Since the bottom of the buffer sound insulation sleeve 4 is sleeved on the outside of the support frame 10, the rotation of the feeding auger 5 can drive the buffer sound insulation sleeve 4 to rotate, so that the plastic particles falling on the buffer sound insulation sleeve The plastic particles on the inner wall are reassembled at the bottom of the soundproof conveying pipe 3. Since the external soundproof cotton sleeve 2 is fixed to the outside of the mixing tank body 1, the external soundproof cotton sleeve 2 can further absorb the noise generated inside the mixing tank body 1, thereby further reducing the noise level generated by the device during use. This device can avoid contact and friction between the plastic particles and the stirring device during the stirring process, thereby preventing noise caused by contact and friction between the plastic particles and the inner wall of the mixing tank body 1, ensuring sufficient stirring while reducing noise level.

[0022] Example 2: A discharge pipe 11 is welded to the bottom of the mixing tank body 1, and a baffle plate 12 is slidably installed inside the discharge pipe 11. The discharge pipe 11 is connected to the interior of the mixing tank body 1. The outer wall of the buffer sound insulation sleeve 4 is close to the inner wall of the mixing tank body 1, and the bottom of the buffer sound insulation sleeve 4 is sleeved on the outside of multiple support frames 10. Four legs 13 are welded to the bottom of the mixing tank body 1. The heat dissipation assembly 7 includes an exhaust pipe 701, and the exhaust pipe 701 is connected to the interior of the mixing tank body 1. A filter 703 is installed inside the exhaust pipe 701 by bolts, and an electric exhaust fan 702 is installed on the top of the exhaust pipe 701.

[0023] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, since the outer wall of the buffer sound insulation sleeve 4 is close to the inner wall of the mixing tank body 1, the friction between the buffer sound insulation sleeve 4 and the inner wall of the mixing tank body 1 during rotation is avoided, and the noise generation is further avoided. Since an air inlet filter tube 9 is welded on one side of the top of the mixing tank body 1, the air inlet filter tube 9 can allow outside air to enter the interior of the mixing tank body 1, and then the rotation of the electric exhaust fan 702 can drive the air inside the mixing tank body 1 to flow out. The air can be filtered through the filter screen 703 to avoid plastic particles being sucked out. The temperature inside the mixing tank body 1 can be lowered by exchanging the air inside the mixing tank body 1, thereby avoiding the melting of plastic particles due to overheating of the internal temperature of the mixing tank body 1. By pulling out the baffle plate 12 slidably installed inside the discharge pipe 11, the plastic particles inside the mixing tank body 1 can flow out of the interior of the mixing tank body 1, thereby facilitating the operator to collect the plastic particles.

[0024] Working principle: When in use, the plastic particles to be stirred and mixed are injected into the interior of the mixing tank body 1 through the feed pipe 14, and then the rotation of the output end of the motor 8 drives the feeding auger 5 to rotate. Since the bottom end of the feeding auger 5 extends out of the soundproof conveying pipe 3, the plastic particles will be brought into the interior of the soundproof conveying pipe 3 through the rotation of the feeding auger 5. As the feeding auger 5 rotates, the plastic particles at the bottom will be transported to the top and then sprinkled from the top of the soundproof conveying pipe 3 and fall back into the interior of the mixing tank body 1. In this process, multiple plastic particles can be mixed. The buffering sound insulation sleeve 4 can prevent the fallen plastic particles from directly contacting the inner wall of the mixing tank body 1, thereby avoiding the noise generated by the plastic particles falling and contacting the inner wall of the mixing tank body 1. The plastic particles that emerge from the top of the soundproof conveying pipe 3 and fall again will fall on the inner wall of the buffering sound insulation sleeve 4. Since the inner wall of the buffering sound insulation sleeve 4 is installed with buffering sound-absorbing cotton, the plastic particles that fall on the buffer can be prevented from falling. The plastic particles on the inner wall of the sound insulation sleeve 4 are buffered and the noise generated by the falling plastic particles is absorbed. Since the bottom of the buffer sound insulation sleeve 4 is sleeved on the outside of the support frame 10, the rotation of the feeding auger 5 can drive the buffer sound insulation sleeve 4 to rotate, so that the plastic particles falling on the inner wall of the buffer sound insulation sleeve 4 are re-gathered at the bottom of the sound insulation conveying pipe 3, and the outside air can be allowed to enter the interior of the mixing tank body 1 through the air inlet filter pipe 9, and then the rotation of the electric exhaust fan 702 can drive the air inside the mixing tank body 1 to flow out. The temperature inside the mixing tank body 1 can be reduced by exchanging the air inside the mixing tank body 1, thereby avoiding the melting of plastic particles caused by overheating of the internal temperature of the mixing tank body 1. Finally, the baffle plate 12 slidably installed inside the discharge pipe 11 is pulled out, so that the plastic particles inside the mixing tank body 1 can flow out of the interior of the mixing tank body 1, so that the operator can collect the plastic particles.
