Description

Technical Field

[0001] This utility model belongs to the field of pellet storage technology, specifically a plastic pellet storage device. Background Technology

[0002] Plastic products refer to a general term for various daily and industrial products made from plastic as the main raw material. Plastic granules, as an indispensable raw material in the plastic processing process, usually need to be stored using plastic granule storage devices.

[0003] In the existing technology, the working principle of some plastic granule storage devices is as follows: after the plastic granules are poured into the feeding hopper, the air generated by the fan blows the granules into the storage device. At this time, the air entering the device is discharged through the exhaust pipe, while the plastic granules remain in the device.

[0004] However, such storage devices have certain limitations: some devices install filters in the exhaust pipe to reduce the risk of particles being discharged with the exhaust pipe. Since some plastic particles have low density and light weight, although the isolation effect of the filter can reduce the discharge of particles, under the action of wind, the particles may be adsorbed on the filter plate, causing the filter plate to be blocked. This problem not only affects the exhaust effect of the device, but also reduces the feeding speed, thereby affecting the overall processing efficiency. Therefore, a plastic particle storage device is proposed to address the above problems. Utility Model Content

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-5This utility model provides a plastic granule storage device, including a storage tank 1; a feeding assembly 2 is provided at the bottom of the storage tank 1; an exhaust pipe 3 is provided on the side wall of the top of the storage tank 1; a filter plate 62 is slidably mounted in the middle of the exhaust pipe 3; a round rod 61 is rotatably connected to the middle of the filter plate 62; a fan 6 is fixedly connected to one end of the round rod 61; a scraper 66 is fixedly connected to the other end of the round rod 61; the side wall of the scraper 66 contacts the side wall of the filter plate 62; an arc-shaped plate 63 is fixedly connected to the side wall of the filter plate 62; a slider 64 is fixedly connected to the side wall of the arc-shaped plate 63; a positioning groove 32 is provided in the middle of the exhaust pipe 3; the slider 64 slides on the inner wall of the positioning groove 32. During operation, the plastic granules can be conveyed into the storage tank 1 through the feeding assembly 2 at the bottom of the storage tank 1. The feeding assembly 2 is existing technology and uses a fan. The plastic granules are blown into the storage tank 1 by force. Since this is existing technology, its working principle is well understood by those skilled in the art, so it will not be described in detail here. When the plastic is fed into the storage tank 1 by the feeding component 2, air is also fed into the storage tank 1. The air entering the storage tank 1 is discharged through the exhaust pipe 3. The filter plate 62 installed inside the exhaust pipe 3 filters the plastic granules in the air, reducing the risk of plastic granules flying out. When the air passes through the exhaust pipe 3, it drives the fan 6 to rotate. The fan 6 drives the round rod 61 to rotate, and the round rod 61 drives the scraper 66 to rotate. The scraper 66 scrapes the end of the filter plate 62, reducing the risk of plastic granules adhering to the filter plate 62 and clogging it. This ensures the flow of the exhaust pipe 3 and the efficiency of feeding.

[0027] Furthermore, such as Figure 3 and Figure 5As shown; a fixing block 44 is fixedly connected to the side wall of the exhaust pipe 3; a rectangular shell 42 is rotatably connected to the side wall of the fixing block 44; a connecting slide plate 41 is slidably connected to the middle of the rectangular shell 42; a spring 43 is fixedly connected to one end of the connecting slide plate 41; the other end of the spring 43 is fixedly connected to the middle of the rectangular shell 42; a sealing cover 4 is fixedly connected to the other end of the connecting slide plate 41; the sealing cover 4 contacts the end of the exhaust pipe 3. During operation, the sealing cover 4 can seal the exhaust pipe 3, ensuring the overall airtightness of the storage tank 1 and improving the storage effect of the storage tank 1 on plastic granules. During feeding, the material is discharged through the exhaust pipe 3. The air will push open the sealing cover 4, and the sealing cover 4 will drive the connecting slide plate 41 to slide on the inner wall of the rectangular shell 42. The connecting slide plate 41 will stretch the spring 43, thus ensuring the smooth exhaust of the exhaust pipe 3. When no material is being added and exhaust is not required through the exhaust pipe 3, the spring 43 will pull the connecting slide plate 41 back to its original position through its own elasticity. The connecting slide plate 41 will drive the sealing cover 4 back to its original position, so that the sealing cover 4 contacts the exhaust pipe 3, thus sealing the exhaust pipe 3. This eliminates the need for workers to use external tools to climb to the top of the storage tank 1 to seal the exhaust pipe 3, improving practicality.

[0028] Furthermore, such as Figure 3 and Figure 5 As shown; a groove 47 is provided on the side wall of the rectangular shell 42; a through groove 46 is provided on one side of the side wall of the rectangular shell 42 located in the groove 47; a limiting block 52 is slidably connected to the inner wall of the through groove 46; a rectangular plate 5 is fixedly connected to the side wall of the limiting block 52; a sliding rod 51 is fixedly connected to the side wall of the rectangular plate 5 located on one side of the limiting block 52; the sliding rod 51 is slidably connected in the middle of the groove 47. During operation, the limiting block 52 can simultaneously limit the rectangular shell 42 and the slider 64. When it is necessary to fully open the sealing cover 4 to maintain the internal components of the exhaust pipe 3, The rectangular plate 5 can be pulled, which will cause the slide bar 51 to slide on the inner wall of the groove 47. At the same time, the rectangular plate 5 will cause the limiting block 52 to slide on the inner wall of the second through groove 46 until the limiting block 52 is fully inserted into the interior of the second through groove 46. At this time, the sealing cover 4 can be pushed. The sealing cover 4 will drive the rectangular shell 42 to rotate on the side wall of the fixed block 44 through the connecting slide plate 41. This will cause the sealing cover 4, which was originally concentric with the exhaust pipe 3, to rotate to the eccentric position of the exhaust pipe 3. In this way, the exhaust pipe 3 will be fully opened, and the worker can easily take out the internal structure of the exhaust pipe 3 for maintenance, which improves practicality.

[0029] Furthermore, such as Figure 3As shown; a limiting groove 65 is provided on the side wall of the slider 64; a limiting block 52 contacts the middle of the limiting groove 65; a through groove 33 is provided on the side wall of the exhaust pipe 3; the outer wall of the limiting block 52 slides on the inner wall of the through groove 33. During operation, when the limiting block 52 is inserted into the inner wall of the limiting groove 65, it will limit the slider 64, thus limiting the filter plate 62 and ensuring the stability of the filter plate 62 in the middle of the exhaust pipe 3. When the limiting block 52 is pulled, it will disengage from the inner wall of the limiting groove 65, thus releasing the limitation on the slider 64. When the sealing cover 4 rotates to one side of the exhaust pipe 3, the filter plate 62 can be removed together by pulling the fan 6. This allows for maintenance of the filter plate 62 and the scraper 66 together, improving practicality.

[0030] Furthermore, such as Figure 3 As shown, a sealing ring 45 is fixedly connected to the end of the sealing cover 4; a sealing groove 31 is opened at the end of the exhaust pipe 3; the sealing ring 45 contacts the inner wall of the sealing groove 31. During operation, the cooperation between the sealing ring 45 and the sealing groove 31 ensures that the sealing cover 4 can improve the sealing performance of the exhaust pipe 3 after it is closed.

[0031] Furthermore, such as Figure 3 As shown, a second spring 53 is sleeved on the outer wall of the slide rod 51; one end of the second spring 53 is fixed to the side wall of the rectangular plate 5; the other end of the second spring 53 is fixed to the side wall of the rectangular shell 42. During operation, the second spring 53, through its own elasticity, always pulls the limiting block 52 toward the limiting groove 65 through the rectangular plate 5, ensuring the stability of the rectangular shell 42 and the filter plate 62 and improving practicality.

[0032] Furthermore, such as Figures 3-4 As shown, multiple sets of arc-shaped plates 63 and sliders 64 are provided; and the multiple sets of arc-shaped plates 63 and sliders 64 are symmetrically arranged with the center line of the filter plate 62 as the axis of symmetry. During operation, the multiple sets of arc-shaped plates 63 and sliders 64 can ensure the stability of the filter plate 62 installed inside the exhaust pipe 3, reduce the risk of the filter plate 62 rotating with the fan 6, and improve practicality.

[0033] Working Principle: The discharge assembly 2 at the bottom of the storage tank 1 can transport plastic granules into the storage tank 1. The discharge assembly 2 is existing technology, which uses wind power to blow the plastic granules into the storage tank 1. Since it is existing technology, its working principle is well understood by those in the field, so it will not be described in detail here. When the plastic is fed into the storage tank 1 by the discharge assembly 2, air is also sent into the storage tank 1. The air entering the storage tank 1 is discharged through the exhaust pipe 3. The filter plate 62 installed inside the exhaust pipe 3 filters the plastic granules in the air, reducing the risk of plastic granules flying out. When the air passes through the exhaust pipe 3, it drives the fan 6 to rotate. The fan 6 drives the round rod 61 to rotate. The round rod 61 drives the scraper 66 to rotate. The scraper 66 scrapes the end of the filter plate 62, reducing the risk of plastic granules adhering to the filter plate 62 and clogging it. This ensures the flow of the exhaust pipe 3 and ensures the efficiency of feeding.

[0034] The sealing cap 4 can seal the exhaust pipe 3, ensuring the overall airtightness of the storage tank 1 and improving the storage effect of the storage tank 1 on plastic granules. When feeding, the air discharged through the exhaust pipe 3 will push the sealing cap 4 open, and the sealing cap 4 will drive the connecting slide plate 41 to slide on the inner wall of the rectangular shell 42. The connecting slide plate 41 will stretch the spring 43, thus ensuring the smooth exhaust of the exhaust pipe 3. When not feeding, and when exhaust is not needed through the exhaust pipe 3, the spring 43 will pull the connecting slide plate 41 back to its original position through its own elasticity. The connecting slide plate 41 will drive the sealing cap 4 back to its original position, so that the sealing cap 4 contacts the exhaust pipe 3, thus sealing the exhaust pipe 3. This eliminates the need for workers to use external tools to climb to the top of the storage tank 1 to seal the exhaust pipe 3, improving practicality.

[0035] The limiting block 52 can simultaneously limit the rectangular shell 42 and the slider 64. When the sealing cover 4 needs to be fully opened to maintain the internal components of the exhaust pipe 3, the rectangular plate 5 can be pulled. The rectangular plate 5 will drive the slider 51 to slide on the inner wall of the groove 47. At the same time, the rectangular plate 5 will drive the limiting block 52 to slide on the inner wall of the second through groove 46 until the limiting block 52 is fully inserted into the second through groove 46. At this time, the sealing cover 4 can be pushed. The sealing cover 4 will drive the rectangular shell 42 to rotate on the side wall of the fixing block 44 through the connecting slide plate 41, so that it is originally concentric with the exhaust pipe 3. The sealing cover 4 is rotated to the eccentric position of the exhaust pipe 3, so that the exhaust pipe 3 will be fully open. The worker can then pull the fan 6 inside the exhaust pipe 3. The fan 6 will drive the filter plate 62 to move through the round rod 61 until the filter plate 62 is completely removed from the inside of the exhaust pipe 3. This allows for maintenance of the filter plate 62 and scraper 66. During installation, the filter plate 62 is directly inserted into the middle of the exhaust pipe 3, and the slider 64 is made to slide into the inner wall of the positioning groove 32. Then the sealing cover 4 is rotated back, and the limiting block 52 is made to insert into the inner wall of the limiting groove 65.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
