Description

Technical Field

[0001] This utility model relates to the field of plastic particle mixing technology, and in particular to a plastic particle mixer with waste gas recovery function. Background Technology

[0002] During the processing of plastics, plastic granules need to be mixed to meet production needs.

[0003] A Chinese utility model patent document with announcement number CN206264175U discloses a plastic particle mixing machine, including a barrel body, a lid on the top of the barrel body, a stirring device at the center of the lower surface of the lid, the stirring device consisting of a rotating shaft and stirring blades extending spirally in the axial direction of the rotating shaft, an exhaust device located on the side of the top of the lid, a bucket-shaped structure at the bottom of the barrel body, a screw at the bottom of the barrel body, the diameter of the spiral blades on the side of the screw gradually decreasing from top to bottom, a support located at the bottom of the barrel body, and a discharge port located on the bottom side of the barrel body. The device uses a mixing unit to thoroughly mix the plastic particles added to the container. An exhaust system is installed on the top of the lid to absorb dust generated during mixing, reducing the amount of dust in the mixed plastic particles. This technology effectively addresses the dust generated during plastic mixing. However, in actual plastic mixing processes, it is often necessary to mix and heat damp materials. The exhaust gas generated during the drying and mixing of materials contains a large amount of steam. Some manufacturers directly use exhaust fans to create ducts to remove the steam, leading to the loss of water resources in the exhaust gas.

[0004] Therefore, we provide a plastic particle mixer with waste gas recovery function to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The problem to be solved by this utility model is to provide a plastic particle mixer with waste gas recovery function, so as to overcome the defects in the prior art.

[0007] (II) Technical Solution

[0008] To solve the aforementioned technical problem, this utility model provides a plastic particle mixer with waste gas recovery function, comprising a main body, a second inner cylinder connected inside the main body, a first inner cylinder connected inside the second inner cylinder, a first mixing cavity formed between the main body and the second inner cylinder, a second mixing cavity rotatably disposed inside the first inner cylinder, and a first heating zone formed between the first inner cylinder and the second inner cylinder.

[0009] The main body is provided with a recycling component at its inner top. The recycling component includes a connecting shaft rotatably disposed at the top of the main body. A scraper that cooperates with the inner top of the main body is connected to the connecting shaft. A spiral guide plate corresponding to one end of the scraper is installed on the inner periphery of the main body. A recycling pipe communicating with the spiral guide plate is provided on the main body.

[0010] A helical blade rod is located inside the first inner cylinder and is connected to a connecting shaft via a speed reduction transmission assembly.

[0011] Different plastic particles are added into the main body through the feed inlet. The controller controls the geared motor to drive the spiral blade rod to rotate. The spiral blade rod carries the material at the bottom of the main body, along with the first inner cylinder, through the second mixing chamber and then through the discharge port into the first mixing chamber. The material in the first mixing chamber falls into the bottom of the main body under the action of gravity and is then circulated and mixed by the spiral blade rod.

[0012] At the same time, the controller controls the operation of the fan and heating tube. The air blown by the fan is heated by the heating tube and then flows into the first heating zone. The hot air heats the first inner cylinder and the second inner cylinder of the first heating zone, so that the material conveyed by the spiral blade rod in the second mixing chamber is heated and dried. The hot air in the first heating zone flows into the first mixing chamber again, so that the material scattered through the discharge port is heated and dried a second time by the hot air in the first mixing chamber during the material distribution process.

[0013] The steam generated during material drying is concentrated on the inner top cover of the main body, forming water droplets. The spiral blade rod drives the connecting shaft to rotate through the reduction transmission assembly. The connecting shaft drives the J-shaped scraper to rotate and scrape on the inner top cover of the main body, causing the water droplets on the inner top cover of the main body to fall into the J-shaped scraper and flow into the spiral guide plate under the action of centrifugal force. The water on the spiral guide plate flows into the recovery pipe through the recovery hole under the action of gravity.

[0014] In some embodiments, the scraper is mounted obliquely on the connecting shaft, and the scraper is arranged in a J-shape.

[0015] In some embodiments, the cross-section of the spiral guide plate is L-shaped.

[0016] In some embodiments, the main body is provided with a recycling hole, through which water on the spiral guide plate flows into the recycling pipe.

[0017] In some embodiments, the main body is connected to a first bracket that cooperates with a speed reduction transmission assembly. The first bracket is located above the first inner cylinder. The speed reduction transmission assembly includes a first rotating shaft that is rotatably connected to the first bracket. The first rotating shaft is fixedly connected to one end of a spiral blade rod. A first pinion is provided on the first rotating shaft.

[0018] In some embodiments, a second rotating shaft is rotatably connected to the first bracket, and a second pinion and a second large gear are arranged sequentially from top to bottom on the second rotating shaft. The first pinion and the second large gear are meshed together, and a first large gear is arranged on the connecting shaft and meshes with the second large gear.

[0019] In some embodiments, the gear ratio of the first pinion, the second gear, the second pinion, and the first gear is 1:3:1:3.

[0020] In some embodiments, the main body is provided with a feed inlet and a discharge outlet, and the bottom of the main body is provided with a geared motor that is connected to the helical blade rod drive.

[0021] In some embodiments, a fan is installed on the base of the main body, and a heating pipe is connected between the second inner cylinder and the fan. The air blown by the fan is heated by the heating pipe and then delivered to the first heating zone and the first mixing chamber. The first heating zone heats the cylinder walls of the first inner cylinder and the second inner cylinder.

[0022] In some embodiments, a material outlet is formed between the first inner cylinder and the first support, the material outlet being lower than one end of the spiral blade rod, a second support is connected between the first inner cylinder and the second inner cylinder, and a third support is connected between the second inner cylinder and the main body.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the plastic particle mixer with waste gas recovery function provided by this utility model has the following advantages:

[0025] This invention uses a recycling component to concentrate the steam generated during material drying onto the inner top cover of the main body, forming water droplets. The spiral blade rod drives the connecting shaft to rotate via a reduction transmission component. The connecting shaft drives a J-shaped scraper to rotate and scrape the inner top cover of the main body, causing the water droplets on the inner top cover to fall into the J-shaped scraper and flow into the spiral guide plate under centrifugal force. The water on the spiral guide plate then flows into the recycling pipe through the recycling hole under gravity, achieving the effect of recovering water vapor in the exhaust gas during the drying process of plastic mixing.

[0064] Different plastic particles are added into the main body 1 through the feed inlet 103. The controller controls the geared motor 2 to drive the spiral blade rod 7 to rotate, so that the spiral blade rod 7 can carry the material at the bottom of the main body 1, together with the first inner cylinder 8, through the second mixing chamber and then through the discharge port 10 into the first mixing chamber. The material in the first mixing chamber falls into the bottom of the main body 1 under the action of gravity and is then circulated and mixed by the spiral blade rod 7.

[0065] At the same time, the controller controls the operation of the fan 4 and the heating tube 5. The air blown by the fan 4 is heated by the heating tube 5 and then flows into the first heating zone. The hot air heats the first inner cylinder 8 and the second inner cylinder 9 in the first heating zone, so that the material conveyed by the spiral blade rod 7 in the second mixing chamber is heated and dried. The hot air in the first heating zone flows into the first mixing chamber again, so that the material scattered through the discharge port 10 is heated and dried a second time by the hot air in the first mixing chamber during the material distribution process in the first mixing chamber.
