Description

Technical Field

[0001] This utility model relates to a dust removal and drying device for coated films, belonging to the field of coated film production technology. Background Technology

[0002] Coated film is a thin film material widely used in many fields. It is also known as coated film or coated membrane. It is a thin film formed by uniformly coating a specific coating material onto the surface of a substrate through a coating process.

[0003] After the coating material is applied to the substrate, it needs to be dried. The drying methods are mainly divided into three categories: natural drying, heating drying, and special drying. Among them, heating drying can be further divided into hot air convection drying, far-infrared radiation drying, and hot air convection plus radiation drying, depending on the heating and curing method.

[0004] Currently, hot air convection drying is a drying method that uses air nozzles to blow air onto the coated surface to dry it. However, since the air contains solid particulate impurities such as dust, these solid particles can be adsorbed and solidified on the surface of the coated film, reducing the product quality of the coated film.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a dust removal and air drying device for coated films, which can solve the problem that solid particles are adsorbed and solidified on the surface of the coated film during the air drying process, resulting in a reduction in the quality of the coated film product.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] The coating film dust removal and drying device includes a housing. Conveyor rollers are rotatably mounted on the outer walls of both sides of the housing. The conveyor rollers are used to input and output the coating film into and out of the housing. The housing contains a dust removal chamber, a heating chamber, and a drying chamber. The dust removal chamber and the heating chamber are located above the drying chamber. A connecting hole is provided between the top of the dust removal chamber and the heating chamber. The coating film is arranged to pass through the drying chamber laterally. A gas delivery pump is installed inside the drying chamber. The inlet of the gas delivery pump is connected to the bottom of the heating chamber. The outlet of the gas delivery pump is connected to a strip air knife through a pipeline. The bottom of the strip air knife has an inclined blower gap.

[0009] Furthermore, multiple filter bags are installed at the bottom of the dust removal chamber, and the top opening of the filter bags is connected to the perforated plate, which is fixedly installed above the dust removal chamber.

[0010] Furthermore, a horizontally arranged blowpipe is installed above the perforated plate, and a blowhole is opened at the bottom of the blowpipe. The blowhole is located above the filter bag, and the blowhole corresponds one-to-one with the filter bag.

[0011] Furthermore, the bottom of the dust removal chamber is inclined, and an air inlet and a dust outlet are provided on one side of the bottom of the dust removal chamber, with the air inlet located above the dust outlet.

[0012] Furthermore, the drying chamber has exhaust holes on its side walls, and the exhaust holes and air inlets are located on the left and right sides of the chamber.

[0013] Furthermore, a heating tube is installed inside the heating chamber, and the heating tube is provided with fins.

[0014] Furthermore, the bottom of the heating chamber has a conical structure, and the bottom of the conical structure has an opening.

[0015] Furthermore, the gas delivery pump is fixed to the inner wall of the housing.

[0016] Furthermore, the air gap is set at a certain angle to the surface of the coated film.

[0017] Furthermore, the housing is fixedly installed on top of the chassis, and the bottom of the chassis is equipped with rollers and supports.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0019] Air is first drawn into the dust removal chamber through the air inlet, filtered through the filter bag, and then enters the heating chamber through the connecting hole. After the air fully absorbs the heat from the heating tube in the drying chamber, it enters the gas delivery pump. The gas delivery pump sends the hot air to the strip air knife. The air knife blows out a thin, long, uniform hot airflow through the air gap to dry the coated film.

[0020] This invention can effectively filter the air to ensure the cleanliness of the hot air used for drying, thus ensuring that the surface of the coated film is dust-free and dry.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a coating film dust removal and drying device, including a box body 1. Conveying rollers 5 are rotatably installed on the outer walls of the left and right sides of the box body 1. The conveying rollers 5 are used to input and output the coating film 6 into and out of the box body 1.

[0027] The interior of the housing 1 is provided with a dust removal chamber 7, a heating chamber 8 and a drying chamber 9. The dust removal chamber 7 and the heating chamber 8 are located above the drying chamber 9, and a connecting hole 10 is provided between the top of the dust removal chamber 7 and the heating chamber 8.

[0028] The coating film 6 is installed transversely through the drying chamber 9.

[0029] Multiple filter bags 11 are installed at the bottom of the dust removal chamber 7. The top opening of the filter bags 11 is connected to the perforated plate 12, which is fixedly installed above the dust removal chamber 7.

[0030] A horizontally arranged blowpipe 15 is installed above the perforated plate 12. The blowpipe 15 has blowholes at its bottom, which are located above the filter bags 11 and correspond one-to-one with the filter bags 11. The blowholes can periodically blow high-speed jets of air toward the top of the filter bags 11, causing the filter bags 11 to expand rapidly from top to bottom and vibrate violently, shaking off the dust from the outer wall of the filter bags 11.

[0031] The bottom of the dust removal chamber 7 is inclined. An air inlet 13 and a dust outlet 14 are provided on one side of the bottom of the dust removal chamber 7. The air inlet 13 is located above the dust outlet 14.

[0032] The heating chamber 8 is equipped with a heating tube 16, which has fins to improve heat exchange efficiency. The heating tube 16 can be an electric heating tube or a heat transfer oil heating tube.

[0033] The bottom of the heating chamber 8 has a conical structure, and the bottom of the conical structure has an opening.

[0034] The drying chamber 9 is equipped with a gas delivery pump 17, which is fixed to the inner wall of the housing 1. The inlet of the gas delivery pump 17 is connected to the bottom of the heating chamber 8, and the outlet of the gas delivery pump 17 is connected to the strip air knife 18 through a pipeline. The bottom of the strip air knife 18 has an inclined blower gap 19, which is set at a certain angle with the surface of the coating film 6.

[0035] The drying chamber 9 has an exhaust port 20 on its side wall, and the exhaust port 20 and the air inlet port 13 are located on the left and right sides of the box body 1.

[0036] The housing 1 is fixedly installed on the chassis 2. The bottom of the chassis 2 is equipped with rollers 3 and supports 4. The housing 1 can be easily moved by the rollers 3 to adjust its position.

[0037] The specific working principle of this utility model is as follows:

[0038] The coating film 6 extends horizontally through the housing 1; at the same time, air is drawn into the dust removal chamber 7 through the air inlet 13, filtered through the filter bag 11, and then enters the heating chamber 8 through the connecting hole 10. After the air fully absorbs the heat from the heating tube 16 in the drying chamber 9, it enters the gas delivery pump 17. The gas delivery pump 17 sends the hot air to the strip air knife 18. The air gap 19 of the strip air knife 18 blows out a thin and long hot airflow with a uniform flow rate to achieve the drying of the coating film 6.
