Description

A Rotary Centrifugal Compaction Chamber Used in Waste Film Blown Film Regeneration System

technical field

The utility model relates to the technical field of plastic film production, in particular to a rotary centrifugal compacting bin used in a waste film blown film regeneration system.

Background technique

At present, in the recycling of waste films, granulation needs to be carried out first, that is to say, the waste films are made into film particles, and then the film particles are processed into films after granulation. However, washing with water is required during the granulation process, which will cause serious environmental pollution, and there are complicated processes in the middle, which need to consume a lot of energy, which does not conform to the production concept of energy saving and environmental protection. Therefore, a waste film blown film regeneration system has been developed. The system can directly process the waste film into a formed film, eliminating the need for granulation. In the process of blown film regeneration, the material needs to be compacted through the compaction chamber, and then sent to the die head of the blown film machine. If a common compaction chamber is used, the compaction of the material is not uniform due to the use of a single blade to compact the material, which affects the product quality of the produced film.

In order to solve the above problems, this case was born.

detailed description

Below by accompanying drawing and embodiment the utility model is described in further detail.

As shown in Fig. 1 to Fig. 5: a rotary centrifugal compacting bin used in a waste film blown film regeneration system, including a fully enclosed bin shell 1. The upper and lower layers of rotary cutter heads are horizontally arranged in the housing 1 . The two-layer rotary cutter head is installed on the rotating shaft 7 and driven by a motor 9 to rotate synchronously. A material extruding space 8 is formed between the two layers of rotary cutter heads, and the outer peripheral wall of the rotary cutter heads fits with the inner wall of the bin shell 1 in a gap. Both the upper rotary cutter head 2 and the lower rotary cutter head 3 include a disc-shaped knife holder 4 and three blades 5 . The three blades 5 are radially and equiangularly arranged on the mounting surface of the tool holder 4 in the shape of fan blades. Holes 6 are provided on the front side of each blade 5 on the tool holder 4 of the upper rotary cutter head 2 . The above-mentioned front side of the blade 5 specifically takes the rotation direction of the rotary cutterhead as a reference direction (the direction indicated by the arrow in FIG. 2 is the rotation direction of the rotary cutterhead). The holes 6 are adjacent to the corresponding blades 5 and extend obliquely downward along the rotation direction of the rotary cutter head and through the thickness direction of the cutter holder 4 . With the high-speed rotation of the upper rotary cutter head 2, the material on the upper rotary cutter head 2 will be squeezed into the material extrusion space 8 through the hole 6 under the action of the blade 5. With the continuous rotation of the disk and the continuous flow of materials into the material extrusion space 8, the materials in the material extrusion space 8 will be rotated and extruded to achieve the purpose of compaction. Through extrusion and rotary compaction of the upper and lower rotary cutter heads, the size of the material is uniform and the compaction is uniform. There is no need to manually crush the material twice, which can effectively improve the processing efficiency and ensure the product quality.

A temperature sensor 10 is arranged in the material extruding space 8, and a frequency converter is arranged on the motor 9, and the temperature sensor 10 and the frequency converter are respectively connected with the main controller. As the material is continuously rotated and extruded, the temperature of the material will continue to rise. The temperature sensor 10 checks the temperature of the material in real time, and transmits the temperature signal to the main controller. Once the temperature exceeds the upper limit set by the main controller, the main controller will reduce the speed of the motor 9 by controlling the frequency converter, thereby reducing the rotation speed. The rotation speed of the type cutter head can reduce the temperature of the material to avoid the material from melting due to excessive temperature.

In order to smoothly introduce materials and additives into the housing 1 , in this embodiment, the material inlet 12 on the housing 1 is connected with a feeding pipe 13 . The position corresponding to the material extrusion space 8 on the bin shell 1 is provided with a material outlet, and the material outlet is provided with a door that can be opened and closed (not shown in the figure, but actually exists).

The material inlet 12 is located on one side of the top of the bin shell 1 . An exhaust fan 11 is provided on the top of the bin shell 1 opposite to the material inlet 12 , and the air outlet of the exhaust fan 11 communicates with the inside of the bin shell 1 . With such a design, during the process of unloading, the air inside the bin shell 1 is continuously extracted by the exhaust fan 11, thereby reducing the resistance of the material falling, increasing the unloading speed, and ensuring that the unloading speed is consistent with the feeding speed of the upper bin 3. Matching to avoid material blockage at the material inlet 12 of the bin shell 1.

In addition, the tank shell 1 is covered with a cooling jacket 14 , and the cooling jacket 14 is provided with a cooling water inlet 141 and a cooling water outlet 142 . The temperature of the compaction chamber can be controlled by the cooling jacket 14, so that the compaction chamber can always maintain an appropriate temperature, so as to avoid damage to the compaction chamber or affect the quality of the internal materials due to excessive temperature.

The above description is based on the embodiment as inspiration, and through the above description content, relevant workers can completely make various changes and modifications within the scope of not departing from the idea of the invention. The technical scope of this utility model is not limited to the content in the description, and the scope of protection must be determined according to the scope of the claims.
