Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing technology, specifically to a high-temperature steam spraying device for corrugated cardboard processing. Background Technology

[0002] In the corrugated cardboard processing, high-temperature steam spraying is a key step in improving the cardboard's flexibility and forming effect. Currently, the high-temperature steam spraying equipment used in the industry has significant shortcomings: traditional equipment suffers from uneven steam spraying, easily leading to excessive moisture or insufficient spraying in certain areas of the corrugated cardboard, affecting processing quality; some equipment has a simple steam channel design, unable to adjust the spray direction and range according to the spraying requirements of different sizes of corrugated cardboard, resulting in poor adaptability; furthermore, most equipment lacks effective sealing and drainage structures, steam leakage not only wastes energy but also easily leads to a humid environment around the equipment, accelerating component corrosion, while condensate accumulation affects steam flow efficiency, making it difficult to meet the demands of large-scale, high-quality corrugated cardboard processing. Utility Model Content

[0003] The purpose of this invention is to provide a high-temperature steam spraying device for corrugated cardboard processing, so as to solve the problems of uneven steam spraying, poor equipment adaptability, and insufficient sealing and drainage in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model provides a high-temperature steam spraying device for corrugated cardboard processing, including two fixed plates on both sides, a square tube between the fixed plates, forming a mist chamber between the fixed plates and the square tube, an air inlet on the outer side of the fixed plates, and an air inlet pipe between the air inlets in the mist chamber; an auxiliary air outlet arranged at intervals is provided on the top of the square tube, and air outlet holes are evenly arranged on the air inlet pipe away from the auxiliary air outlets; two symmetrical mounting profiles are provided on the outer side of the square tube corresponding to the auxiliary air outlets, and a first air chamber, a rising channel, and a second air chamber are formed between the two mounting profiles from bottom to top, and a jet nozzle is provided on the top of the mounting profile.

[0005] Furthermore, the jet nozzle is positioned on top of the two mounting profiles.

[0006] Furthermore, the jet nozzle is positioned on the side of one of the mounting profiles.

[0007] Furthermore, a control valve is provided on the outside of the air intake pipe.

[0008] Furthermore, the jet nozzle is connected to the second air chamber and the jet nozzle is straight.

[0009] Furthermore, positioning plates are provided on the sides of the two mounting profiles for fixing, and a sealing strip is provided between the first air chamber and the square tube.

[0010] Furthermore, the ascending channel is a series of channels arranged at intervals, connecting the first air chamber and the second air chamber.

[0011] Furthermore, one of the fixing plates is provided with a drain outlet.

[0012] The beneficial effects of this utility model are as follows: 1. Uniform steam injection: The evenly arranged air outlets on the air inlet pipe ensure that the steam enters the mist chamber evenly, and the auxiliary air outlets arranged at intervals on the top of the square tube allow the steam to enter the first air chamber smoothly. The spaced rising channels further optimize the steam flow and avoid local steam accumulation. Finally, the steam is evenly sprayed out from the straight jet nozzle, covering the corrugated cardboard processing area, preventing uneven spraying in some areas and ensuring the quality of cardboard processing.

[0013] 2. High adaptability and flexible adjustment: The jet nozzle can be set on the top of two mounting profiles (to achieve top spraying) or on the side of one mounting profile (to achieve side spraying) according to the corrugated cardboard processing requirements, adapting to the spraying needs of corrugated cardboard of different specifications and processing scenarios; the control valve on the outside of the air inlet pipe can adjust the steam intake volume, further improving the flexibility of equipment use.

[0014] 3. Sealing, energy saving, and drainage protection: The positioning plates on the sides of the two mounting profiles ensure the overall stability of the equipment structure. The sealing strip between the first air chamber and the square tube effectively prevents steam leakage and reduces energy waste. The drain port on the fixed plate can drain the condensate in the mist chamber in a timely manner, avoiding the accumulation of condensate that affects steam circulation. At the same time, it prevents the damp environment around the equipment from causing component corrosion and extends the service life of the equipment. Attached Figure Description

[0028] Reference Figures 1 to 7 As shown, an embodiment of a high-temperature steam spraying device for corrugated cardboard processing according to the present invention includes two fixed plates 1 on both sides, a square tube 2 between the fixed plates 1, and a mist chamber 3 formed between the fixed plates 1 and the square tube 2. A drain outlet 16 is provided on one of the fixed plates 1, an air inlet 4 is provided on the outside of the fixed plates 1, an air inlet pipe 5 is provided between the air inlets 4 in the mist chamber 3, and a control valve 13 is provided on the outside of the air inlet pipe 5. The top of the square tube 2 is provided with auxiliary air outlets 6 arranged at intervals. The air inlet pipe 5 is provided with air outlets 7 evenly arranged at a position away from the auxiliary air outlets 6. Two symmetrical mounting profiles 8 are provided on the outer side of the square tube 2 corresponding to the position of the auxiliary air outlets 6. Positioning plates 14 are provided on the sides of the two mounting profiles 8 for fixing. A sealing strip 15 is provided between the first air chamber 9 and the square tube 2. A first air chamber 9, an ascending channel 10, and a second air chamber 11 are formed sequentially from bottom to top between the two mounting profiles 8. The ascending channel 10 is a channel arranged at intervals, connecting the first air chamber 9 and the second air chamber 11. An air nozzle 12 is provided on the top of the mounting profile 8. The air nozzle 12 can be located on the top of the two mounting profiles 8 or on the side of one of the mounting profiles 8. The air nozzle 12 is connected to the second air chamber 11 and is straight.

[0029] Gas flow direction: Gas enters the intake pipe 5 from the intake port 4, enters the mist chamber 3 from the exhaust port 7 at the bottom of the intake pipe 5, enters the first air chamber 9 from the auxiliary exhaust port 6 on the mist chamber 3, enters the second air chamber 11 from the rising channel 10, and finally exits from the jet port 12.

[0030] The working principle and specific operation process of this utility model are as follows: Equipment installation and commissioning: According to the layout of the corrugated cardboard processing production line, fix the equipment at the designated work position by using the positioning plate 14 on the side of the mounting profile 8, ensuring that the air nozzle 12 is aligned with the cardboard processing area; select the position of the air nozzle 12 (top or side) according to the spraying requirements. If top spraying is required, set the air nozzle 12 on the top of the two mounting profiles 8. If side spraying is required, set it on the side of the mounting profile 8; check whether the sealing strip 15 between the first air chamber 9 and the square tube 2 is installed in place to ensure good sealing; open the drain valve 16 on the fixing plate 1 to ensure that the condensate can be discharged smoothly.

[0031] Steam parameter setting and air intake: Connect the external high-temperature steam source to the air inlet 4 on the outside of the fixed plate 1 through a pipe. Adjust the control valve 13 on the outside of the air intake pipe 5 according to the material, thickness and other parameters of the corrugated cardboard to set a suitable steam intake volume. Open the control valve 13 and the high-temperature steam enters the air intake pipe 5 from the air inlet 4. During the flow along the pipe, it slowly enters the mist chamber 3 from the air outlet 7 evenly set at the bottom of the pipe to avoid steam impact causing local airflow turbulence.

[0032] Steam Circulation and Uniform Spraying: After a brief buffering period inside the mist chamber 3, the steam enters the first chamber 9 smoothly from bottom to top through the auxiliary air outlets 6 spaced apart on the top of the square tube 2. The sealing strip 15 prevents steam from leaking from the connection between the first chamber 9 and the square tube 2. After the steam accumulates in the first chamber 9, it enters the second chamber 11 uniformly through the spaced rising channels 10. The spaced design of the rising channels 10 prevents the steam from forming eddies during circulation. Finally, the steam is ejected from the straight jet nozzle 12 connected to the second chamber 11, uniformly covering the surface of the corrugated cardboard, completing the spraying treatment.

[0033] Condensate drainage and equipment maintenance: During spraying, the condensate generated in the mist chamber 3 is promptly discharged through the drain port 16 on the fixed plate 1 to prevent condensate accumulation from affecting steam quality and flow efficiency. After processing, first shut off the external steam source, then close the control valve 13 of the air inlet pipe 5. After the residual steam in the equipment is completely discharged, close the drain port 16 valve. Regularly check the sealing performance of the sealing strip 15; replace it promptly if it is aged or damaged. Clean the air outlet 7, auxiliary air outlet 6, and rising channel 10 of the air inlet pipe 5 to prevent impurities from clogging and affecting steam flow. Check the fixing status of the positioning plate 14; tighten it promptly if it is loose to ensure stable equipment operation.

[0034] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
