Description

Technical Field

[0001] This utility model relates to the field of plastic manufacturing technology, specifically to a noise reduction and cooling device for plastic granules. Background Technology

[0002] With the rapid development of the plastics processing industry, the production and application of plastic granules are becoming increasingly widespread. However, a significant problem often arises during the production process of plastic granules, especially when the granules are cooled from a high temperature and enter storage or subsequent processing stages—noise pollution. When plastic granules fall directly into the production chamber, significant noise is generated due to the collision between the granules and the chamber, the impact between the granules themselves, and the air turbulence caused by the falling granules. This noise not only adversely affects the production environment but may also threaten the hearing health of operators, and it does not meet the environmental protection and occupational health requirements of modern industrial production.

[0003] Traditional cooling equipment often neglects noise reduction design, resulting in ineffective control of noise generated during the cooling and transport of plastic granules. Therefore, there is an urgent need for cooling equipment that can effectively reduce the noise from falling plastic granules to improve the production environment, protect the health of operators, and enhance the overall level of the plastics processing industry.

[0004] This utility model is a noise reduction and cooling device for plastic particles proposed under such background. It aims to effectively solve the noise problem generated when plastic particles fall through innovative design, and provide the industry with a more environmentally friendly and healthy solution. Utility Model Content

[0005] The purpose of this invention is to provide a noise reduction and cooling device for plastic granules to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a noise reduction and cooling device for plastic granules, comprising: a tank and a fan body, wherein an inner frame plate is arranged in a ring inside the tank, a cavity is arranged inside the inner frame plate, a material hole is arranged at the bottom end of the inner cavity of the inner frame plate, and a paddle is extended from the bottom end of the outer side of the inner frame plate.

[0007] A material guide pipe is provided in a ring at the lower end of the outer side of the tank body, an air inlet pipe is provided at the bottom of the tank body, an air delivery pipe is provided at the top of the blower body, and a cooling structure is provided at the top of the air delivery pipe.

[0008] Furthermore, the inner cavity of the inner frame plate has a semi-arc structure, and the inner frame plate is arranged in a multi-layered annular staggered arrangement inside the tank, which facilitates the entry of material particles into the tank. The material particles can either enter the inner cavity of the inner frame plate or directly contact the surface of the paddle.

[0009] Furthermore, the deflector bends towards the center point inside the tank, and the deflector is fixedly connected to the inner frame plate, so that the surface of the deflector can intercept some material particles, thereby slowing down the overall descent speed of the material particles.

[0010] Furthermore, the connection heights of the feed pipe and the air inlet pipe are different, with the connection height of the air inlet pipe being lower than that of the feed pipe. This ensures that the airflow from the air inlet pipe does not affect the normal discharge of material particles from inside the feed pipe.

[0011] Furthermore, the cooling structure includes a wind duct, a first air guide layer, a second air guide layer, a third air guide layer, and an air concentrator layer. The wind duct is located at the bottom of the air inlet pipe. The first air guide layer is located at the upper end of the inside of the wind duct. The second air guide layer is located at the bottom of the first air guide layer. The third air guide layer is located at the bottom of the second air guide layer. An air concentrator layer is located at the middle of the bottom of the inside of the wind duct. The area of ​​the bottom opening of the air concentrator layer is equal to the area of ​​the connection port of the air supply pipe, so that the air concentrator layer can completely absorb the air force output by the air supply pipe.

[0012] Furthermore, the geometric centers of the first, second, and third wind-guiding layers are on the same straight line, which facilitates the gradual diffusion and extraction of wind-driven gases from the wind-gathering layer, thereby reducing the impact force of the wind-driven gases.

[0013] Furthermore, the wind-gathering layer has an inverted bowl-shaped structure, and the upper area of ​​the wind-gathering layer is smaller than the semi-enclosed cross-sectional area of ​​the third air-guiding layer, which facilitates the wind-gathering layer to temporarily gather gas inside the wind-gathering layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When material particles are introduced into the tank, the inner cavity of the inner frame plate can accept some of the material particles, and the inner frame plate provides a relief path for some of the material particles. At the same time, the material hole at the bottom of the inner frame plate also provides an outlet channel for the material particles. The remaining material is gradually bounced out by the deflector at the bottom of the inner frame plate. The deflector directly decelerates the material particles during the descent process, which effectively reduces the speed of the material particles during the descent process and reduces the collision of the material particles with the inner wall of the tank, thereby reducing the noise generated.

[0016] 2. This utility model uses a fan body to guide airflow into the interior of the air duct. The air duct then guides the airflow into the air-gathering layer. After the airflow is gathered to a certain extent, it is guided in stages into the third, second, and first air-guiding layers. The first, second, and third air-guiding layers gradually expand to the surface of the air duct. The air duct then guides the airflow into the air inlet pipe. The air inlet pipe is designed to cool the interior of the tank. In this way, after the first, second, and third air-guiding layers gradually expand the airflow, the air inlet pipe guides the expanded airflow from inside the air duct into the interior of the tank. Furthermore, the airflow inside the tank blows upwards, which also slows down the descent of material particles inside the tank. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6As shown, a noise reduction and cooling device for plastic granules includes: a tank body 1 and a fan body 6. An inner frame plate 2 is arranged in a ring inside the tank body 1. A cavity is arranged inside the inner frame plate 2. A material hole 8 is arranged at the bottom end of the inner cavity of the inner frame plate 2. A paddle 9 is extended from the bottom end of the outer side of the inner frame plate 2.

[0026] A material guide pipe 7 is provided in a ring at the lower outer side of the tank body 1, an air inlet pipe 3 is provided at the bottom of the tank body 1, an air conveying pipe 5 is provided at the top of the blower body 6, and a cooling structure 4 is provided at the top of the air conveying pipe 5.

[0027] Furthermore, since the inner frame plate 2 is arranged in multiple rings inside the tank body 1, and the cavity inside the inner frame plate 2 can store and receive some material particles, the speed of the material particles falling into the inner cavity of the inner frame plate 2 is reduced by the inner structure of the inner frame plate 2. In addition, the material hole 8 at the bottom of the inner frame plate 2 provides a channel for the material particles to be further discharged. At the same time, the deflector 9 at the bottom extension of the inner frame plate 2 is bent upward at a certain angle, and the surface of the deflector 9 is in direct contact with the falling material particles, thereby quickly reducing the falling speed of the material particles. Therefore, the falling speed of all material particles entering the tank body 1 is directly reduced by the deflector 9 and the inner cavity of the inner frame plate 2, thereby reducing the noise generated by the material particles hitting the inner wall of the tank body 1.

[0028] This has resulted in the following effects and novel technologies:

[0029] This invention provides a noise reduction and cooling device for plastic granules, which achieves the dual effects of significantly reducing the noise of falling plastic granules and effectively cooling them. The multi-layered annular inner frame plate 2 inside the tank 1 forms multiple cavities. These cavities not only store and receive some of the material granules, but also effectively block and slow down the descent speed of the granules through their internal structure. The material hole 8 at the bottom of the inner frame plate 2 provides an outlet channel for the material granules, while the extended paddle 9 bends upward at a certain angle to directly contact the falling material granules, further reducing the descent speed of the granules and decreasing the noise generated by the granules hitting the inner wall of the tank 1.

[0030] The semi-circular cross-section design of the inner cavity of the inner frame plate 2 and the multi-layer annular staggered arrangement structure ensure that the material particles can smoothly enter the interior of the tank 1. They can enter the inner cavity of the inner frame plate 2 or directly contact the surface of the paddle 9, realizing the gradual deceleration and discharge of the material particles. The paddle 9 bends towards the center point of the inner side of the tank 1 and is fixedly connected to the inner frame plate 2, effectively stopping some of the material particles and further slowing down the overall descent speed.

[0031] In addition, the connection heights of the feed pipe 7 and the air inlet pipe 3 are different. The connection height of the air inlet pipe 3 is lower than that of the feed pipe 7, which ensures that the airflow from the air inlet pipe 3 will not interfere with the normal discharge of material particles from the inside of the feed pipe 7, thus achieving smooth transmission and cooling of material particles.

[0032] This utility model, through the synergistic effect of the inner frame plate 2, the material hole 8, and the lever 9, as well as the reasonable layout of the guide pipe 7 and the air inlet pipe 3, effectively reduces the speed and collision of plastic granules during the descent process, significantly reduces noise, and at the same time achieves cooling of the material granules, providing an efficient and environmentally friendly solution for plastic granule production.

[0033] like Figures 1-6 As shown, a noise reduction and cooling device for plastic granules includes a cooling structure 4 comprising a duct 41, a first air guide layer 42, a second air guide layer 43, a third air guide layer 44, and an air-gathering layer 45. The duct 41 is located at the bottom of the air inlet pipe 3. The first air guide layer 42 is located at the upper end of the duct 41. The second air guide layer 43 is located at the bottom of the first air guide layer 42. The third air guide layer 44 is located at the bottom of the second air guide layer 43. The air-gathering layer 45 is located at the middle of the bottom of the duct 41. The area of ​​the bottom opening of the air-gathering layer 45 is equal to the area of ​​the connection port of the air supply pipe 5.

[0034] The rest are as follows: the blower body 6 and the air duct 5 draw the gas into the air-gathering layer 45 at the bottom of the air duct 41. The air-gathering layer 45 has an inverted bowl-shaped structure. After the gas is gathered to a certain extent in the inner cavity of the air-gathering layer 45, it is discharged. The third air guide layer 44, the second air guide layer 43 and the first air guide layer 42 expand the wind-powered gas discharged from the air-gathering layer 45 step by step. When the first air guide layer 42 discharges the wind-powered gas to the outside of the air duct 41, the air inlet pipe 3 forms multiple air columns and guides them into the bottom of the tank 1. At this time, the transmission path of the air columns inside the tank 1 is from bottom to top. Since the output path of the material particles is from top to bottom, the air columns can not only cool the inside of the tank 1, but also reduce the speed of the material particles falling straight down, thereby optimizing the noise reduction effect.

[0035] This has resulted in the following effects and novel technologies:

[0036] This invention provides a noise reduction and cooling device for plastic granules. Its cooling structure 4 achieves both efficient cooling and significant noise reduction through a multi-layered airflow design. The air duct 41 contains, from top to bottom, a first airflow guide layer 42, a second airflow guide layer 43, a third airflow guide layer 44, and a bottom air-gathering layer 45. The air-gathering layer 45 adopts an inverted bowl-shaped structure, with its bottom opening area equal to the connection port area of ​​the air duct 5, ensuring smooth gas outflow.

[0037] The blower body 6 and the air duct 5 work together to draw gas into the air gathering layer 45 at the bottom of the air duct 41. The air gathering layer 45 effectively gathers the gas and then discharges it. Subsequently, the gas expands step by step through the third air guiding layer 44, the second air guiding layer 43 and the first air guiding layer 42, and is finally discharged to the outside of the air duct 41 by the first air guiding layer 42. The air inlet pipe 3 forms multiple air columns with the discharged gas and guides them into the bottom of the tank 1.

[0038] These air columns travel upwards within tank 1, creating convection with the downward-flowing material particles. These air columns not only provide uniform cooling within tank 1 but also reduce the linear descent speed of the material particles through airflow resistance, thus significantly reducing noise generated during particle fall. This design optimizes noise reduction, making the equipment quieter and more stable during operation.

[0039] This invention achieves efficient cooling and effective noise reduction of plastic granules through the multi-layered airflow design of the cooling structure 4 and the air column convection mechanism, thereby improving the working performance and environmental protection level of the equipment and providing an advanced and reliable solution for plastic granule production.

[0040] Working Principle: When using this plastic granule noise reduction and cooling equipment, the material granules are first poured into the tank 1. The inner frame plate 2 is arranged in multiple rings inside the tank 1, and the cavity inside the inner frame plate 2 can hold some of the material granules, while the remaining material granules directly enter the tank 1. The deflector 9 extending from the bottom of the inner frame plate 2 can directly decelerate the material granules. At the same time, the material hole 8 at the bottom of the inner frame plate 2 provides an outlet channel for some material granules. Therefore, the falling speed of all the material granules entering the tank 1 is slowed down, so the sound generated by the material granules hitting the inside of the tank 1 is reduced, thereby achieving the noise reduction effect. At this time, the user turns on the blower body 6, and the blower body 6 introduces the gas into the air supply pipe 5, and the air supply pipe 5 introduces the gas into the air duct 41. The bottom air-gathering layer 45 has an inverted bowl-shaped structure. When the air-gathering layer 45 gathers the gas to a certain extent, it diffuses it upwards. At the same time, the third air-guiding layer 44, the second air-guiding layer 43 and the third air-guiding layer 44 gradually expand the dispersion area and degree of the gas. The top first air-guiding layer 42 expands the wind-force gas to the maximum extent and then introduces it into the air inlet pipe 3. The air inlet pipe 3 gathers and aggregates the wind-force gas into multiple gas columns and introduces them into the bottom of the tank 1. At this time, multiple air columns formed by wind-force gas are emitted from the bottom of the tank 1. The air column guide path is from bottom to top, so the temperature inside the tank 1 will be reduced. The speed at which the material particles inside the tank 1 fall will also be affected by the upward force of the wind-force gas. This is the working principle of the plastic particle noise reduction and cooling equipment.

[0041] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
