Description

Technical Field

[0001] This utility model belongs to the field of drying cylinder technology, and in particular relates to a vacuum cyclone drying cylinder structure for processing polypropylene granules. Background Technology

[0002] Polypropylene granules are granular solid materials formed from polypropylene (PP) as the main component through polymerization, which are then processed. It is one of the most common commercial forms of polypropylene resin and a fundamental raw material for subsequent plastic product processing (such as injection molding, extrusion, and blow molding).

[0003] Existing vacuum cyclone drying cylinder structures for polypropylene granule processing are commonly used in polypropylene granule drying equipment, which employs methods such as hot air circulation drying or vacuum drying. However, commonly used hot air drying equipment suffers from low thermal efficiency and uneven drying. Due to granule accumulation, uneven heating between the interior and surface can easily occur, resulting in some granules being over-dried while others remain undried. In view of this, we propose a vacuum cyclone drying cylinder structure for polypropylene granule processing. Utility Model Content

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

[0005] In view of this, the present invention provides a vacuum cyclone drying cylinder structure for polypropylene granule processing, comprising:

[0006] The housing has mounting frames fixedly installed on both sides of its interior, and heat-conducting pipes are fixedly installed in both mounting frames, with the two heat-conducting pipes facing each other.

[0007] An air intake cylinder is fixedly installed on one side inside the housing and located between two heat-conducting pipes. A heat-conducting cylinder is rotatably installed inside the air intake cylinder, and one end of the heat-conducting cylinder is rotatably connected to one side inside the housing.

[0008] An adjustment component is disposed inside the housing and is used to adjust the movement of the two mounting frames;

[0009] A drive assembly is mounted on the housing and is used to drive the heat-conducting cylinder to rotate.

[0010] In the above technical solution, the adjusting component further includes a slide rod, which is fixedly installed on one side of the inside of the housing. The outer wall of the slide rod is slidably connected to two mounting frames. A bidirectional threaded rod is rotatably installed on the other side of the inside of the housing. The two threads on the bidirectional threaded rod have opposite directions of rotation. The outer wall of the bidirectional threaded rod is threadedly connected to the two mounting frames.

[0011] In the above technical solution, the adjustment component further includes a mounting plate, which is fixedly installed on the outer side wall of the housing. A first motor is fixedly installed on the top surface of the mounting plate, and one end of the output shaft of the first motor passes through the outer side wall of the housing and is fixedly connected to one end of a bidirectional threaded rod.

[0012] In the above technical solution, the driving component further includes a first gear, which is rotatably mounted on one side of the housing. One end of the first gear passes through one side of the housing and is fixedly connected to one end of the heat-conducting cylinder. A second gear is provided below the first gear, and one end of the second gear is rotatably connected to one side of the housing. The second gear meshes with the first gear.

[0013] In the above technical solution, the drive assembly further includes a mounting bracket, which is fixedly mounted on one side of the housing and located at the other end of the second gear. A second motor is fixedly mounted on one side of the mounting bracket, and one end of the output shaft of the second motor passes through one side of the mounting bracket and is fixedly connected to the other end of the second gear.

[0014] In the above technical solution, a baffle is slidably installed on the other side of the box, a sleeve is fixedly installed on one side of the baffle, a limit block is fixedly installed on the outer wall of the box, and the same limit rod is movably connected between the limit block and the sleeve.

[0015] In the above technical solution, furthermore, an air outlet pipe is fixedly installed on the top surface of the box.

[0016] The beneficial effects of this utility model are:

[0017] This vacuum cyclone drying cylinder structure for polypropylene granule processing involves the operator placing the polypropylene granules to be dried into the heat-conducting cylinder. The cylinder is then sealed by a sliding baffle and secured with a limiting rod passing through a limiting block and a clamping sleeve, ensuring a relatively sealed space inside the cylinder. Simultaneously, depending on the characteristics of the granules to be dried, the first motor is activated. The motor's output shaft drives a bidirectional threaded rod to rotate. Combined with the guiding action of a sliding rod, the two mounting frames move the heat-conducting pipes synchronously in opposite directions to optimize the heating range. During the drying process, the heat-conducting pipes release heat after being connected to a heat source, heating the air inside the cylinder. Simultaneously, the second motor is started, driving the second gear to rotate through its output shaft. The first gear meshing with the second gear rotates accordingly, thereby driving the heat-conducting cylinder inside the air inlet to rotate at high speed. After the external dry airflow enters through the air inlet, it forms a swirling flow under the rotation of the heat-conducting cylinder. The swirling airflow fully contacts the heat emitted by the heat-conducting pipes on both sides, forming high-temperature swirling air. After the polypropylene granules enter the box, the moisture on the surface and inside of the granules evaporates rapidly under the action of the high-temperature swirling air. Since the air outlet pipe on the top of the box can be connected to a vacuum device, the air with high moisture content is extracted in time under negative pressure, accelerating the cycle of moisture evaporation and discharge.

[0030] The equipment comprises a housing 1, with mounting frames 10 fixedly installed on both sides of its interior. Each mounting frame 10 contains a heat-conducting pipe 11, which is arranged opposite to the housing 1. An air inlet cylinder 14 is fixedly installed on one side of the housing 1, located between the two heat-conducting pipes 11. A heat-conducting cylinder 15 is rotatably installed inside the air inlet cylinder 14, with one end of the heat-conducting cylinder 15 rotatably connected to one side of the housing 1. An adjustment assembly is located inside the housing 1 and is used to adjust the movement of the two mounting frames 10. A drive assembly is located on the housing 1 and is used to drive the heat-conducting cylinder 15 to rotate. During use, the worker places the polypropylene granules to be dried into the heat-conducting cylinder 15, then closes the housing 1 using a sliding baffle 2, and uses a limiting rod 18 passing through a limiting block 16 and a retaining sleeve 17 to secure it, ensuring a relatively sealed space inside the housing 1. Simultaneously, a first motor 5 can be started according to the characteristics of the granules to be dried. The output shaft of the first motor 5... The bidirectional threaded rod 13 rotates, and with the guiding action of the slide rod 12, the two mounting frames 10 drive the heat-conducting pipes 11 to move synchronously in opposite directions to optimize the heating range. During the drying process, the heat-conducting pipes 11 release heat after being connected to the heat source to heat the air inside the chamber 1. At the same time, the second motor 9 is started, and its output shaft drives the second gear 7 to rotate. The first gear 6, which meshes with the second gear 7, rotates accordingly, thereby driving the heat-conducting cylinder 15 inside the air inlet cylinder 14 to rotate at high speed. After the external drying airflow enters through the air inlet cylinder 14, it forms a swirling flow under the rotation of the heat-conducting cylinder 15. The swirling airflow fully contacts the heat emitted by the heat-conducting pipes 11 on both sides to form high-temperature swirling air. After the polypropylene granules enter the chamber 1, the moisture on the surface and inside of the granules evaporates rapidly under the action of the high-temperature swirling air. Since the air outlet pipe 3 on the top surface of the chamber 1 can be connected to a vacuum device, the air with high moisture content is extracted in time under negative pressure, accelerating the cycle of moisture evaporation and discharge.
