Description

Technical Field

[0001] This utility model relates to the field of plastic granule processing, specifically to a plastic granule dust recovery device. Background Technology

[0002] PBT modified plastic is a high-performance engineering material with good residual toughness and fatigue resistance, heat resistance, weather resistance, excellent electrical properties, and low water absorption. Reinforcement and flame-retardant modification can significantly improve its heat resistance, modulus, dimensional stability, and flame retardancy, making it widely used in the automotive, home appliance, and other industries.

[0003] Dust is inevitably generated during the granulation process of PBT modified plastics. The dust mixed in the PBT modified plastic granules not only reduces the quality of the PBT modified plastic granules, but also causes pollution to the workshop due to the dust flying around. Therefore, it is necessary to use a dust recovery device to collect the dust.

[0004] According to Chinese Patent No. CN218928317U, a dust collection device for PBT modified plastic particles is disclosed. This utility model uses a fan to generate suction, and through a connecting pipe, the dust is absorbed inside the box. The dust is separated by a partition, and an inlet pipe is provided to further absorb the dust that slides off the particles screened by the slide plate, and collect the dust inside the collection box.

[0005] Regarding the aforementioned patent content, a filter plate is provided so that plastic particles can fall downward through the filter plate, thereby separating dust from the plastic particles. However, because a large number of plastic particles slide onto the filter plate, some of the plastic particles may clog the filter plate, making it difficult for subsequent plastic particles entering the filter plate to fall downward through the filter plate, and affecting the efficiency of dust extraction and recovery. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a plastic particle dust recycling device to solve the technical problem that a large number of plastic particles will accumulate on the filter plate and thus easily cause the filter plate to become clogged.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a plastic particle dust recovery device, comprising a housing and a collection box. The housing is equipped with an anti-clogging component, which includes a filter disc installed inside the housing, a rotating shaft mounted on the housing via a bearing, a motor mounted on one side of the top of the housing, and an air inlet cylinder connected to one side of the housing. A pusher plate is installed below one side of the rotating shaft, a first gear is connected to the top of the rotating shaft, a second gear is connected to the output end of the motor, a movable shaft is connected to the air inlet cylinder via a bearing, a third gear is installed at the top of the movable shaft, and a driving bevel gear is connected to the bottom of the movable shaft. A mounting frame is installed inside the air inlet cylinder, and a connecting shaft is connected to the mounting frame via a bearing. A fan blade is installed at one end of the connecting shaft, and a driven bevel gear is installed at the other end of the connecting shaft.

[0008] By adopting the above technical solution, when the connecting shaft rotates, it will drive the fan blades to rotate. When the fan blades rotate, they will accelerate the circulation speed of the surrounding air and allow external air to enter the air intake cylinder.

[0009] Furthermore, a dustproof net is installed on one side of the air intake cylinder, and a partition net is provided on the other side of the air intake cylinder.

[0010] By adopting the above technical solution, the dustproof net can filter the incoming air and prevent external dust from entering the housing through the air intake.

[0011] Furthermore, a dust collection box and a support plate are respectively installed on the lower side of the other side of the housing, and a dust collection box is slidably disposed on the top of the support plate.

[0012] By adopting the above technical solution, the support plate can support the dust collection box, and the dust collection box can collect dust.

[0013] Furthermore, a fan is installed on the top of the dust collection box, and the air inlet of the fan is connected to a first exhaust pipe extending into the housing, and the air outlet of the fan is connected to an air supply pipe extending into the dust collection box.

[0014] By adopting the above technical solution, when it is necessary to extract dust, the fan can be started, and the fan can extract the dust inside the casing through the first exhaust pipe.

[0015] Furthermore, a second suction pipe extending into the interior of the housing is connected to one side of the first suction pipe, and the interior of the housing is provided with two guide plates.

[0016] By adopting the above technical solution, the guide plate is set so that the plastic particles can roll on top of it, and the second suction pipe can extract the dust inside the shell.

[0017] Furthermore, a spring is installed on one side of the top of the dust collection box, and a pressing plate is connected to the top of the spring. A pressure rod penetrating into the dust collection box is provided at the bottom of the pressing plate.

[0018] By adopting the above technical solution, when the button is pressed, the button will drive the pressure rod to move down, and at the same time squeeze the spring, so that the spring is compressed.

[0019] Furthermore, a dust removal frame is installed at the bottom of the pressure rod, and a sealing ring is provided between the pressure rod and the dust collection box.

[0020] By adopting the above technical solution, when the pressure rod moves, it will drive the dust removal frame to move. When the dust removal frame moves, it can scrape off the dust attached to the inner wall of the dust guide box, causing the dust to fall off, thereby cleaning the dust attached to the inner wall of the dust guide box.

[0021] Furthermore, an exhaust port is provided on one side of the dust collection box, a filter screen is installed inside the exhaust port, and a feed hopper is also installed on the top of the housing.

[0022] By adopting the above technical solution, the exhaust port is designed to facilitate air discharge, while the filter screen is designed to intercept dust and prevent dust from being discharged through the exhaust port.

[0023] Furthermore, the second gear meshes with the first gear and the third gear respectively, and the diameter of the third gear is smaller than the diameter of the second gear.

[0024] By adopting the above technical solution, when the second gear rotates, it will drive the first gear and the third gear to rotate.

[0025] Furthermore, a material discharge port is provided at the bottom of the housing, and the collection box is located directly below the material discharge port.

[0026] By adopting the above technical solution, plastic particles can fall into the collection box through the discharge port, and the collection box can collect the plastic particles.

[0027] In summary, the present invention has the following main advantages:

[0028] 1. This utility model is equipped with an anti-clogging component. When plastic granules are added into the housing through the feed hopper, the motor can be started. The motor drives the second gear to rotate, which in turn drives the first gear to rotate. The first gear drives the rotating shaft to rotate, which in turn drives the pusher plate to rotate. This allows the pusher plate to move the plastic granules on the filter plate, preventing the plastic granules from clogging the filter plate and affecting their downward fall. It also improves the cleaning efficiency of the filter plate. At the same time, it eliminates the need for manual cleaning of the plastic granules accumulated on the filter plate, and the cleaning process is simple and convenient.

[0029] 2. Simultaneously, when the second gear rotates, it drives the third gear to rotate, which in turn drives the movable shaft to rotate, which in turn drives the driving bevel gear to rotate, and then drives the driven bevel gear to rotate. Since the diameter of the third gear is smaller than that of the second gear, and the diameter of the driven bevel gear is smaller than that of the driving bevel gear, the driven bevel gear rotates faster, which drives the connecting shaft to rotate rapidly. When the connecting shaft rotates, it drives the fan blades to rotate, which accelerates the airflow speed of the surrounding air and allows external air to enter the air intake cylinder and then into the housing. This blows the dust on the right side of the housing towards the first exhaust pipe, making it easier for the first exhaust pipe to extract the dust, thereby improving the dust extraction efficiency and accelerating the airflow speed.

[0030] 3. By installing a mesh screen, plastic particles can be prevented from entering the air intake cylinder, and the dust filter can filter the incoming air to prevent external dust from entering the housing through the air intake cylinder. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] A plastic particle dust collection device, such as Figures 1-6 As shown, the device includes a housing 1 and a collection box 2. The housing 1 has an anti-clogging component 9 inside. A dust guide box 10 and a support plate 16 are installed on the lower side of the other side of the housing 1. A dust collection box 17 is slidably mounted on the top of the support plate 16. The support plate 16 can support the dust collection box 17, which can collect dust. The top of the dust collection box 17 fits against the bottom of the dust guide box 10. The top of the support plate 16 has two sliding grooves, and each of the two sliding grooves has a slider inside. The slider is connected to the bottom of the dust collection box 17, which is convenient for taking out or placing the dust collection box 17. A fan 6 is installed on the top of the dust guide box 10. The air inlet of the fan 6 is connected to a first suction pipe 5 extending into the housing 1, and the air outlet of the fan 6 is connected to an air supply pipe 8 extending into the dust guide box 10. When it is necessary to extract dust, the fan 6 can be started. The operation of the fan 6 can extract the dust inside the housing 1 through the first suction pipe 5. Supports are provided on both sides of the bottom of the housing 1 to support the housing 1.

[0042] See Figures 1-3 The first suction pipe 5 is connected to a second suction pipe 7 extending into the housing 1. The housing 1 has two guide plates 4 inside. The top of the guide plates 4 is smooth. The guide plates 4 are designed so that plastic particles can roll on their tops. The second suction pipe 7 can extract dust from the inside of the housing 1. The dust collection box 10 has an exhaust hole 14 on one side. A filter screen 15 is installed in the exhaust hole 14. The exhaust hole 14 is designed to facilitate air discharge, while the filter screen 15 is designed to intercept dust and prevent dust from being discharged through the exhaust hole 14. The top of the housing 1 is also equipped with a feed hopper 18, which allows workers to add plastic particles into the housing 1 through the feed hopper 18. The bottom of the housing 1 has a discharge port 3. The collection box 2 is located directly below the discharge port 3 so that plastic particles can fall into the collection box 2 through the discharge port 3. The collection box 2 can collect the plastic particles.

[0043] Specifically, the anti-clogging component 9 includes a filter disc 901 installed inside the housing 1, a rotating shaft 903 mounted on the housing 1 via a bearing, a motor 905 mounted on one side of the top of the housing 1, and an air inlet 914 connected to one side of the housing 1. A pusher plate 902 is installed below one side of the rotating shaft 903. A first gear 904 is connected to the top of the rotating shaft 903. A second gear 906 is connected to the output end of the motor 905. The second gear 906 meshes with the first gear 904 and the third gear 907 respectively. The diameter of the third gear 907 is smaller than the diameter of the second gear 906. When the second gear 906 rotates, it will drive the first gear 904 and the third gear 907 to rotate. The bottom of the pusher plate 902 is in contact with the top of the filter disc 901 so that the plastic particles accumulated on the filter disc 901 can be moved when the pusher plate 902 rotates.

[0044] Specifically, a movable shaft 908 is connected to the air intake cylinder 914 via a bearing. A third gear 907 is installed at the top of the movable shaft 908, and a driving bevel gear 909 is connected to the bottom of the movable shaft 908. A mounting bracket 912 is installed inside the air intake cylinder 914, and a connecting shaft 911 is connected to the mounting bracket 912 via a bearing. A fan blade 913 is installed at one end of the connecting shaft 911. When the connecting shaft 911 rotates, it drives the fan blade 913 to rotate. When the fan blade 913 rotates, it accelerates the flow speed of the surrounding air and allows external air to enter the air intake cylinder 914. A driven bevel gear 910 is installed at the other end of the connecting shaft 911. The driving bevel gear 909 meshes with the driven bevel gear 910. The diameter of the driving bevel gear 909 is larger than the diameter of the driven bevel gear 910 in order to increase the rotation speed of the connecting shaft 911, so that the connecting shaft 911 can quickly drive the fan blade 913 to rotate.

[0045] Example 2:

[0046] Based on the above embodiment 1, in order to prevent external dust from entering the housing 1 through the air inlet 914, the following structure will be provided.

[0047] See Figures 1-3 A dustproof net 916 is installed on one side of the air intake 914. The dustproof net 916 can filter the incoming air and prevent external dust from entering the housing 1 through the air intake 914. A partition net 915 is provided on the other side of the air intake 914. The partition net 915 can prevent plastic particles from entering the air intake 914.

[0048] Example 3:

[0049] Based on the above embodiment 1, the following structure will be set up to facilitate the cleaning of dust adhering to the inner wall of the dust collection box 10.

[0050] See Figure 1 , Figure 3 and Figure 4 A spring 12 is installed on one side of the top of the dust collection box 10, and a pressing plate 19 is connected to the top of the spring 12. A pressure rod 11 is provided at the bottom of the pressing plate 19, which penetrates into the dust collection box 10. When the pressing plate 19 is pressed, the pressing plate 19 will drive the pressure rod 11 to move down, and at the same time squeeze the spring 12, so that the spring 12 is compressed. A dust cleaning frame 13 is installed at the bottom of the pressure rod 11. The outer wall of the dust cleaning frame 13 is in contact with the inner wall of the dust collection box 10. A sealing ring is provided between the pressure rod 11 and the dust collection box 10. When the pressure rod 11 moves, it will drive the dust cleaning frame 13 to move. When the dust cleaning frame 13 moves, it can scrape off the dust attached to the inner wall of the dust collection box 10, so that the dust falls off, and thus the dust attached to the inner wall of the dust collection box 10 can be scraped and cleaned.

[0051] The working principle of this utility model is as follows: First, before using the device, connect the power supply. Then, the user inserts the slider at the bottom of the dust collection box 17 into the groove on the support plate 16 and pushes the dust collection box 17 to move it to the bottom of the dust guide box 10. Then, place the collection box 2 at the bottom of the housing 1. Next, add the plastic granules into the housing 1 through the feed hopper 18 and start the fan 6 and motor 905. The motor 905 drives the second gear 906 to rotate, which in turn drives the first gear 904 to rotate. The first gear 904 then drives the rotating shaft 903 to rotate. The movement of the fan 6 causes the pusher plate 902 to rotate, which in turn pushes the plastic particles on the filter plate 901 to move. The fan 6 can also extract dust from inside the housing 1 through the first exhaust pipe 5. The plastic particles fall down onto the guide plate 4 and slide on it. At the same time, the second exhaust pipe 7 can extract dust around the guide plate 4. The dust enters the dust collection box 10 through the air supply pipe 8 and falls down into the dust collection box 17. The air is discharged through the exhaust port 14. The filter screen 15 can filter the air to prevent dust from being discharged through the exhaust port 14.

[0052] The plastic granules continue to fall downwards and will fall into the discharge port 3 and then into the collection box 2, thus collecting the plastic granules. When the second gear 906 rotates, it will drive the third gear 907 to rotate. The third gear 907 will drive the movable shaft 908 to rotate, which will drive the active bevel gear 909 to rotate, and then drive the driven bevel gear 910 to rotate. Since the diameter of the third gear 907 is smaller than the diameter of the second gear 906, and the diameter of the driven bevel gear 910 is smaller than the diameter of the active bevel gear 909, the driven bevel gear 910 rotates faster and drives the connecting shaft 911 to rotate quickly. When the connecting shaft 911 rotates, it will drive the fan blade 913 to rotate. When the fan blade 913 rotates, it will accelerate the circulation speed of the surrounding air and allow the outside air to enter the air inlet 914 and then enter the housing 1, so as to blow the dust on the right side of the housing 1 towards the first exhaust pipe 5, so that the first exhaust pipe 5 can extract the dust.

[0053] When it is necessary to scrape and clean the dust adhering to the inner wall of the dust collection box 10, the operator can press the button 19. The button 19 will drive the pressure rod 11 to move down, and at the same time squeeze the spring 12, so that the spring 12 is compressed. When the pressure rod 11 moves, it will drive the dust cleaning frame 13 to move. When the dust cleaning frame 13 moves, it can scrape off the dust adhering to the inner wall of the dust collection box 10, causing the dust to fall off, thereby scraping and cleaning the dust adhering to the inner wall of the dust collection box 10.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
