Description

Technical Field

[0001] This utility model relates to the technical field of polypropylene production and processing, specifically to a drying device for processing polypropylene granules. Background Technology

[0002] Drying is a crucial step in the production of polypropylene granules. Traditional drying methods typically employ hot air drying or oven drying, but these methods suffer from low drying efficiency, high energy consumption, and uneven drying. These problems are particularly pronounced in large-scale production, leading to inconsistent product quality and increased production costs.

[0003] Specifically, traditional drying methods primarily rely on hot air convection to remove moisture from polypropylene granules. However, this method often results in uneven heat distribution, where some granules may not be fully dried while others may be over-dried, thus affecting the overall quality of the product. To address this, we propose a drying device for processing polypropylene granules. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for processing polypropylene granules, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for processing polypropylene granules, comprising a drying tank, an air inlet pipe and an air outlet pipe fixedly installed on both sides of the outer end of the drying tank, a drive motor fixedly installed on the upper end of the drying tank, a drive rod rotatably installed inside the drying tank, the upper end of the drive rod being fixedly connected to the lower end of the output shaft of the drive motor, a plurality of carrier plates inserted and installed inside the drying tank, the carrier plates being sleeved around the drive rod, a first annular toothed block inserted and installed around the drive rod, and a second annular toothed block fixedly installed on the lower end of the carrier plate, the first annular toothed block and the second annular toothed block meshing with each other.

[0006] Preferably, the carrier plate adopts a grooved plate structure with a central recess, the carrier plate has an insertion cavity on its periphery, the drive rod is located in the insertion cavity, and a limiting insert plate that is inserted into the outside of the insertion cavity is fixedly installed on the inner wall of the drying tank.

[0007] Preferably, a first C-shaped block is fixedly installed in the middle of the carrier plate, a second annular toothed block is fixedly installed at the lower end of the first C-shaped block, and a second C-shaped block is rotatably installed at the upper end of the first C-shaped block. Both the first C-shaped block and the second C-shaped block are located around the drive rod.

[0008] Preferably, the drive rod has a threaded groove on its periphery, and a threaded sleeve that is threadedly connected to the threaded groove is rotatably installed at the lower end of the first annular tooth block.

[0009] Preferably, a limiting groove is formed on the periphery of the drive rod, and a limiting slider is fixedly installed on the inner wall of the first annular tooth block, and the limiting slider is slidably installed in the limiting groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This drying equipment for processing polypropylene granules utilizes the interlocking effect between the first and second annular toothed blocks to cause the rotating drive rod to drive the carrier plate and the polypropylene granules on the upper part of the carrier plate to vibrate up and down, thereby improving the drying effect of the polypropylene granules.

[0012] This drying equipment for processing polypropylene granules allows for the installation and removal of a carrier plate around the drive rod via a rotating connection between a first C-shaped block and a second C-shaped block. Furthermore, the position of the carrier plate can be adjusted via a threaded connection between a threaded sleeve and a threaded groove, thereby further improving the performance of this invention.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a drying device for processing polypropylene granules, including a drying tank 1. An air inlet pipe 11 and an air outlet pipe 12 are fixedly installed on both sides of the outer end of the drying tank 1, respectively. A drive motor 2 is fixedly installed on the upper end of the drying tank 1. A drive rod 21 is rotatably installed inside the drying tank 1. The upper end of the drive rod 21 is fixedly connected to the lower end of the output shaft of the drive motor 2. A plurality of carrier plates 22 are inserted and installed inside the drying tank 1. The carrier plates 22 are sleeved around the drive rod 21. A first annular toothed block 3 is inserted and installed around the drive rod 21. A second annular toothed block 31 is fixedly installed on the lower end of the carrier plate 22. The first annular toothed block 3 and the second annular toothed block 31 mesh with each other.

[0024] Working principle: When in use, pour polypropylene granules into the upper part of each carrier plate 22, connect the air inlet pipe 11 to the external hot air equipment, and hot air can be injected into the drying tank 1 and discharged through the exhaust pipe 12. When the hot air passes through the drying tank 1, it can dry the polypropylene granules on the upper part of each carrier plate 22.

[0025] Start the drive motor 2, and drive the drive rod 21 to rotate through its output shaft. Through the plug-in connection between the carrier plate 22 and the drying tank 1, the rotating first annular toothed block 3 can drive the carrier plate 22 and the polypropylene particles on the upper end of the carrier plate 22 to vibrate through the interlocking effect between the first annular toothed block 3 and the second annular toothed block 31. This allows the polypropylene particles to fully contact the hot air and improves the drying effect on the polypropylene particles.

[0026] As a further description of the above technical solution: the carrier plate 22 adopts a grooved plate structure with a central recess, and an insertion cavity 23 is opened on the periphery of the carrier plate 22. The drive rod 21 is located in the insertion cavity 23, and a limiting insertion plate 24 that is inserted into the outer side of the insertion cavity 23 is fixedly installed on the inner wall of the drying tank 1; a first C-shaped block 25 is fixedly installed in the middle of the carrier plate 22, a second annular toothed block 31 is fixedly installed at the lower end of the first C-shaped block 25, and a second C-shaped block 26 is rotatably installed at the upper end of the first C-shaped block 25. Both the first C-shaped block 25 and the second C-shaped block 26 are located on the periphery of the drive rod 21.

[0027] Specifically, when installing the carrier plate 22, the insertion cavity 23 and the drive rod 21 are inserted into each other, and the outer end of the insertion cavity 23 is inserted into the limiting plate 24. At this time, the first C-shaped block 25 is sleeved on the periphery of the drive rod 21, and then the second C-shaped block 26 is rotated on the upper end of the first C-shaped block 25 to achieve the effect of limiting the carrier plate 22 between the drying tank 1 and the drive rod 21.

[0028] As a further description of the above technical solution: a threaded curve groove 36 is provided on the periphery of the drive rod 21, and a threaded sleeve 33 that is threadedly connected to the threaded curve groove 36 is rotatably installed at the lower end of the first annular tooth block 3; a limiting slide groove 34 is provided on the periphery of the drive rod 21, and a limiting slider 35 is fixedly installed on the inner wall of the first annular tooth block 3, and the limiting slider 35 is slidably installed in the limiting slide groove 34.

[0029] Specifically, after the carrier plate 22 is installed, when it is necessary to adjust its height, the threaded sleeve 33 is rotated around the drive rod 21. With the drive rod 21 connected to the limit slider 35 and the limit groove 34, the movement direction of the first annular tooth block 3 is restricted, so that the rotating threaded sleeve 33 can drive the first annular tooth block 3 to move through the threaded connection between it and the threaded curve groove 36, so that it contacts the second annular tooth block 31 at the lower end of the carrier plate 22, thereby achieving the effect of adjusting the height of the carrier plate 22.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
