[0002] When using PET materials in production, it is necessary to remove dust from the surface of PET sheets or granules to ensure that there are no impurities in subsequent production and processing, thereby improving the quality of the finished product. Therefore, an environmentally friendly dust removal device for PET material production is needed. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides an environmentally friendly dust removal device for PET material production, comprising:

[0004] The outer shell has an internal airflow channel;

[0005] An air pulse generator, the air outlet of which is connected to the inlet of the air flow channel;

[0006] A sieve cylinder, which forms a chamber for containing PET material, includes connecting plates on both sides, several connecting columns fixed between the two connecting plates, and sieve holes formed by the interval between two adjacent connecting columns. A rotating shaft is eccentrically fixed to the outside of the connecting plates. The sieve cylinder is rotatably connected to the inner wall of the outer shell through the rotating shaft. At least one of the connecting plates has an inlet and outlet, and a sealing cover is detachably connected to the inlet and outlet.

[0007] Filter cotton is installed in the airflow channel located below the sieve cylinder.

[0008] Through the above technical solution, the air pulse generator can generate pulsed airflow, which can blow out the dust on the surface of the PET material and adsorb it through the filter cotton.

[0009] The outer wall of the sealing cap and the inner wall of the inlet / outlet are provided with mating threads. Through this technical solution, the threaded connection of the sealing cap allows for the insertion of PET material. For example, an opening can be made in the outer shell, allowing the cap to be detachably connected in an existing manner. The cap can be opened when material needs to be added and closed when dust removal is required.

[0010] It also includes a connector with a central opening that fits the chamber. The connector is ring-shaped or frame-shaped, and a connecting post passes through and is fixed in place to prevent the connecting post from deforming due to centrifugal force when the screen cylinder rotates.

[0011] One of the rotating shafts passes through the housing and is connected to a drive motor. The motor can be fixed to the housing using an existing bracket.

[0012] An air outlet is provided below the filter cotton to allow air to be discharged.

[0013] A connecting shaft is fixed between the two connecting plates, and a filter cotton is wrapped around the connecting shaft. The filter cotton can be fixed to the outside of the connecting shaft by fasteners or clamps. Because the filter cotton has a certain thickness and deformation force, it can contact the surface of the PET material and adsorb dust when the screen cylinder rotates.

[0014] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, can realize dust removal in the screen cylinder and dust blowing through the air pulse generator, and the blown-away dust is absorbed by the filter cotton and will not disperse in the air flow channel.

[0019] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model concept, and are only a part of the embodiments of this utility model. The specific and direct description of related structures is only for the convenience of understanding this utility model, and the specific features do not necessarily or directly limit the scope of implementation of this utility model.

[0020] Referring to the accompanying drawings, this utility model adopts the following technical solution: This utility model provides an environmentally friendly dust removal device for PET material production, comprising:

[0021] Outer shell 1, with internal airflow channel 2;

[0022] The existing structure of the air pulse generator 3 has an air outlet 14 connected to the inlet of the air flow channel 2;

[0023] The sieve cylinder 4 has a chamber 5 inside for containing PET material. It includes connecting plates 6 on both sides, and several connecting columns 7 are fixed between the two connecting plates 6. The interval between two adjacent connecting columns 7 forms a sieve hole 8. A rotating shaft 9 is eccentrically fixed to the outside of the connecting plate 6. The sieve cylinder 4 is rotatably connected to the inner wall of the outer shell 1 through the rotating shaft 9. At least one of the connecting plates 6 has an inlet and outlet, and a sealing cover 10 is detachably connected to the inlet and outlet. The size of the sieve hole 8 can be adjusted according to the PET material to be dusted.

[0024] A filter cotton 11 is installed in the air flow channel 2 located below the screen cylinder 4. The filter cotton 11 can be held by an existing mesh frame, that is, the filter cotton 11 is held between the upper mesh plate and the lower mesh plate, and the upper mesh plate and the lower mesh plate are connected by fasteners.

[0025] Through the above technical solution, since the air pulse generator 3 can generate pulse airflow, it can blow out the dust located on the surface of the PET material and adsorb it through the filter cotton 11.

[0026] The outer wall of the sealing cap 10 and the inner wall of the inlet / outlet are provided with mating threads. Through this technical solution, the threaded connection of the sealing cap 10 allows for the insertion of PET material. For example, an opening can be made in the outer casing 1, which is detachably connected to the cap in an existing manner. The cap can be opened when material needs to be added and closed when dust removal is required.

[0027] It also includes a connector 12, which has a hollowed-out portion in the middle that fits the chamber 5. The connector 12 is annular or frame-shaped, and the connecting post 7 passes through the connector 12 for fixation. This is to prevent the connecting post 7 from being deformed by centrifugal force when the screen cylinder 4 rotates.

[0028] One of the rotating shafts 9 passes through the housing 1 and is connected to a drive motor 13. The motor can be fixed to the housing 1 using an existing bracket.

[0029] An air outlet 14 is provided below the filter cotton 11 to allow air to be discharged.

[0030] A connecting shaft 15 is fixed between the two connecting plates 6. The connecting shaft 15 is wrapped with filter cotton 11. The filter cotton 11 can be fixed to the outside of the connecting shaft 15 by fasteners or clamps. Since the filter cotton 11 has a certain thickness and deformation force, it can contact the surface of the PET material and adsorb dust when the screen cylinder 4 rotates.

[0031] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, can realize dust removal in the screen cylinder 4 and dust blowing through the air pulse generator 3, and the dust blown away is absorbed by the filter cotton 11 and will not disperse in the air channel 2.
