Technical Field

[0001] The utility model relates to the technical fields of mechanical engineering and fluid mechanics, in particular to a steam injection device. Background Art

[0002] When traditional steam injection devices are in operation, they are prone to generating loud noise or vibration due to changes in steam flow rate, pressure fluctuations during the injection process, and the internal structure of the device. These noise and vibrations not only affect the stability and life of the device, but may also cause damage to the surrounding environment and even damage the hearing of workers.

[0003] When traditional steam injection devices mix steam and water, uneven mixing often occurs due to problems such as improper steam injection angle or mismatch between steam flow rate and water flow rate, which leads to reduced efficiency and brings many inconveniences to users.

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the steam injection device proposed in the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are in a very simplified form and all use non-precise proportions. The terms "center", "lateral", "length", "width", "height", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "side" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, and do not indicate or imply that the steam injection device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation of the present invention, but is only used to conveniently and clearly assist in explaining the purpose of the embodiment of the present invention. In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, please refer to the accompanying drawings.

[0024] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them. They are not used to limit the conditions for the implementation of this utility model and therefore have no substantive technical significance. Any structural modifications, changes in proportional relationships, or adjustments in size should still fall within the scope of the technical contents disclosed in this utility model without affecting the effects and purposes that can be achieved by this utility model.

[0025] The specific structure of the steam injection device is described below:

[0026] See also Figure 1 and Figure 2 The steam injection device of this embodiment includes a first tube body 1 and a second tube body 2. The first tube body 1 and the second tube body 2 are both arranged along a first direction. A portion of the first tube body 1 is disposed within the second tube body 2, forming a cavity 3 between the first tube body 1 and the second tube body 2. In this embodiment, the first direction is the length direction of the first tube body 1 and the second tube body 2.

[0027] Please continue reading Figures 2 to 4 The first tube body 1 includes a first portion 101 and a second portion 102. The first portion 101 is connected to the second portion 102, and a transition portion 1011 is provided on the first portion 101 near the second portion 102. One end of the transition portion 1011 is connected to the second portion 102. Preferably, the transition portion 1011 and the second portion 102 can be welded or other processes with good sealing properties. A flange 4 is also connected to one end of the first portion 101 for connecting to a steam source.

[0028] Furthermore, the transition portion 1011 decreases in diameter as it approaches the second portion 102. The wall thickness of the first tube body 1 is smaller than that of the second tube body 2. Steam flows from the first tube body 1 into the second tube body 2. The diameter change of the transition portion 1011 improves the concentration of steam, thereby increasing the efficiency of production operations. The first tube body 1 and the second tube body 2 have equal outer diameters and are coaxially arranged along the first direction.

[0029] Please continue reading Figure 5 The second part 102 is closed at one end away from the first part 101, and the first holes 1021 are evenly and annularly arranged on the surface of the second part 102 along its end face. Preferably, in this embodiment, six first holes 1021 are annularly arranged along the end face direction of the second part 102.

[0030] The direction of the first hole 1021 forms an angle of 30° to 60° with the direction along its end surface pointing toward the center of the second portion 102. This creates a rotational force when steam and water mix within the second portion 102. The angle, combined with the length of the first hole 1021 provided by the wall thickness of the second portion 102, effectively reduces noise. The mixture can be more efficiently ejected into the cavity 3, driving the flow of water throughout the cavity and accelerating energy conversion.

[0031] Please continue reading Figure 2 and Figure 3 The second tube body 2 has a second hole 201 at the end away from the second portion 102, and the outer diameter of the first tube body 1 matches the second hole 201. Preferably, the second hole 201 and the first tube body 1 are connected by welding to improve sealing. The second tube body 2 also has third holes 202 uniformly disposed on the surface away from the second portion 102 to guide water into the cavity 3.

[0032] The specific working process of the steam injection device according to the embodiment of the present invention is described below:

[0033] Steam is passed into the first tube body 1 from one end of the flange 4, and steam and water are mixed in the first tube body 1 to form a mixture. During this process, the steam always maintains a positive pressure, and the mixture passes into the cavity 3 through the first hole 1021 in the second part 102. Under the action of the first hole 1021, the mixture generates centrifugal force, thereby achieving a rotation effect and spraying out to the end away from the first part 101. At the same time, water is continuously filled into the first tube body 1 through the third hole 202, so that continuous production operation is carried out.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-mentioned embodiments only express several implementation methods of the utility model. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several variations and improvements can be made, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
