Description
Technical Field
[0001] The utility model belongs to the field of steam equipment, and in particular relates to a steam injection device. Background Art
[0002] During the production process of cardboard, the lamination process of cardboard requires appropriate humidity to assist lamination. Generally, a steam injection device is used to humidify it. The ejected steam has smaller particles and is more widely distributed, thereby effectively improving the lamination of the cardboard.
[0003] However, on the cardboard production line, the steam particles sprayed out by the existing steam spraying device are disordered, the steam sprayed onto the cardboard is unevenly distributed, and the humidity of different parts of the cardboard is inconsistent, resulting in poor cardboard adhesion. In order to improve the adhesion of the cardboard and thus increase the steam spraying amount, unnecessary steam loss is increased. Summary of the invention
[0004] The utility model aims to provide a steam injection device which can guide the angle of steam injection and improve the use efficiency of steam.

[0007] By adopting the above technical solution, steam is filled into the accommodating cavity through the first hole, and then the steam is ejected through the second hole on one side of the main shell. A guide plate is provided in the second hole, so that a guide channel is formed between the guide plates, and the steam injection angle is controlled to improve the uniformity of steam distribution on the paperboard, reduce unnecessary steam input, and improve the use efficiency of steam.

By adjusting the second hole setting on the outer shell, the efficiency of the steam output can be adjusted, and the overall structure can be customized. The angle of the steam injection can also be adjusted by rotating the angle of the guide plate to increase the steam injection range.
[0022] In one of the embodiments, a mounting member is fixedly provided on a side of the main shell facing away from the first hole, and a mounting hole is provided on the mounting member.
[0023] By adopting the above technical solution, the device is installed through the mounting hole on the mounting part.

[0024] In one of the embodiments, a third hole is further provided at the end of the main shell, the third hole is located at the bottom of the main shell, and the third hole is connected to the accommodating cavity.
[0025] By adopting the above technical solution, due to the condensation effect of steam, part of the condensed water of the steam will remain in the containing chamber, and the accumulation of condensed water will affect the steam temperature in the containing chamber, causing the steam to condense faster in the containing chamber and pass through the third hole, so that the condensed water can be discharged in time to ensure the steam injection efficiency.

[0038] like Figures 1 to 6 The steam injection device shown comprises a main shell 10, wherein a receiving chamber 11 is provided in the main shell 10, wherein a first hole 121 is provided at one end of the main shell 10, wherein the first hole 121 is connected to the receiving chamber 11, and steam is filled into the receiving chamber 11 through the first hole 121, wherein a second hole 131 is further provided at one side of the main shell 10, wherein the second hole 131 is connected to the receiving chamber 11, and then steam is injected out through the second hole 131; and further comprises a plurality of guide plates 132, wherein in the present embodiment, the guide plates 132 are matched in the second holes 131, and the plurality of guide plates 132 are arranged at an angle, and guide channels 133 are formed between the plurality of guide plates 132, so as to control the steam injection angle, improve the uniformity of steam distribution on the paperboard, reduce unnecessary steam input, and improve the use efficiency of steam.
[0039] like Figures 1 to 6As shown, the main shell 10 is further described as follows:
[0040] The main shell 10 includes an inner shell 12 and an outer shell 13. The outer shell 13 is provided with the second hole 131. The connection between the two ends of the guide plate 132 and the outer shell 13 forms a rotation axis. The guide plate 132 is rotatably connected to the outer shell 13. One side of the inner shell 12 is open. The outer shell 13 covers the opening of the inner shell 12. The separation design of the inner shell 12 and the outer shell 13 is convenient for installation. By adjusting the setting of the second hole 131 on the outer shell 13, the efficiency of steam output can be adjusted, and the overall structure can be customized. The angle of steam injection can also be adjusted by rotating the guide plate 132. , improving the steam injection range; the outer shell 13 and the inner shell 12 form the accommodating chamber 11, and the first hole 121 is located at one end of the inner shell 12; the inner shell 12 is also fixedly provided with a mounting member 14 on the side away from the first hole 121, and the mounting member 14 is provided with a mounting hole 141. The device is installed through the mounting hole 141 on the mounting member 14. Since the mounting member 14 is located at the back of the main shell 10, the steam injection angle can also be adjusted by rotating the external connecting member connected to the mounting hole 141, thereby further improving the steam injection range of the device and improving the adjustability of the device.
[0041] like Figure 5 to Figure 6 As shown, the inner shell 12 is further described:
[0042] There are multiple first holes 121. By increasing the number of the first holes 121, a first tube 122 is provided in each first hole 121. The first tube 122 extends along the first hole 121 into the accommodating chamber 11. A spray hole 1221 is provided on one side of the first tube 122, so that steam is directly input into the accommodating chamber 11, thereby increasing the rate at which steam is filled into the accommodating chamber 11. The first tube 122 can also extend to different positions of the accommodating chamber 11 to increase the uniformity of steam distribution in the accommodating chamber 11, thereby making the output steam distribution more uniform. Multiple isolation plates 123 are fixedly provided in the inner shell 12.

[0046] Along the radial direction of the main shell 10, the length of the main warehouse 111 is greater than the length of the auxiliary warehouse 112, so the capacity of the main warehouse 111 can be increased. Due to the change in steam demand, the steam injection demand borne by the main warehouse 111 is increased, and the steam input to the first tube 122 connected to the auxiliary warehouse 112 is reduced, thereby simplifying the complexity of steam input control; since the capacity of the main warehouse 111 is the largest, the diameter of the first tube 122 connected to the main warehouse 111 is greater than the diameter of the first tube 122 connected to the auxiliary warehouse 112, which can shorten the steam filling time in the main warehouse 111 and improve the steam injection efficiency of the main warehouse 111.
[0047] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
