[0003] Since the baffles in the prior art are fan-shaped and distributed in a stepped spiral shape around the central tube, the fluid resistance is large when the fluid flows, and the heat exchange tube is easily vibrated and damaged. In view of this, the inventor conducted in-depth research on the above defects in the prior art, and thus the present invention was created. Utility Model Content
[0004] The utility model aims to solve at least one of the technical problems in the above-mentioned technology to a certain extent. To this end, the utility model aims to provide a baffle structure, which is provided with a baffle ring and a support rod, wherein the support rod is provided with a plurality of support rods, and a gap is formed between two adjacent support rods. When the fluid flows, the fluid passes through the gap, so that the heat exchange tube is not easily damaged by vibration.
[0005] In order to achieve the above-mentioned purpose, the utility model proposes a deflection structure, including a deflection group, the deflection group includes a deflection ring and a support rod, one end of the support rod is fixedly connected to an inner wall of the deflection ring, and the other end of the support rod is fixedly connected to the other inner wall of the deflection ring. The support rods are arranged in multiple numbers, and a gap is formed between two adjacent support rods.
[0006] Furthermore, the plurality of support rods are parallel to each other, and the distances between two adjacent support rods are equal.
[0007] Furthermore, the outer diameter of the support rod is smaller than the distance between two adjacent support rods.
[0008] Furthermore, the baffle ring is in a circular ring shape.
[0009] Furthermore, the baffle groups are arranged in at least two groups, and each baffle group is connected together by a distance mechanism.
[0010] Furthermore, each baffle ring of each baffle group is provided with a through hole; the distance mechanism includes a pull rod and a distance tube, the pull rod passes through the through holes of different baffle groups, the distance tube is sleeved on the pull rod, one end of the distance tube rests on a baffle ring, and the other end of the distance tube rests on another baffle ring.
[0011] Furthermore, a plurality of perforations are arranged on the baffle ring, and the plurality of perforations are evenly distributed on the baffle ring.
[0012] Furthermore, the support rods of two adjacent groups of baffles are oriented in different directions.
[0013] Furthermore, the baffle groups are arranged in two groups or four groups.
[0014] After adopting the above structure, the baffle structure of the utility model has at least the following beneficial effects:
[0015] First, during installation, the baffle structure is set in the cylinder of the heat exchange equipment, and a heat exchange tube can be set in the cylinder, and the heat exchange tube passes through the gap formed between two adjacent support rods. During heat exchange, steam is input into the cylinder, and water is input into the heat exchange tube. The steam passes through the gap, thereby heating the water in the heat exchange tube. Since there are multiple support rods, there are more gaps, and the fluid (steam) passes through different gaps, so that the heat exchange tube is not easy to vibrate and damage the heat exchange equipment.
[0016] Second, since the multiple support rods are parallel to each other and the distance between two adjacent support rods is equal, during installation, the heat exchange tube can be passed through the gap so that one side of the heat exchange tube contacts one support rod and the other side of the heat exchange tube contacts the other support rod, thereby limiting the heat exchange tube.
[0017] Third, by setting up multiple baffle groups, after the heat exchange tube passes through the gaps of different baffle groups, the heat exchange tube can be limited from different directions to prevent the heat exchange tube from moving. Different baffle groups play a role in regulating the flow direction and distribution of the fluid. Different baffle groups make the fluid form alternating laminar flow and turbulent flow, thereby improving the heat exchange effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0026] like Figures 1 to 5 As shown, a baffle structure of the utility model includes a baffle group 1, the baffle group 1 includes a baffle ring 11 and a support rod 12, one end of the support rod 12 is fixedly connected to an inner wall of the baffle ring 11, and the other end of the support rod 12 is fixedly connected to the other inner wall of the baffle ring 11, and the support rod 12 is arranged in multiple numbers, and a gap 2 is formed between two adjacent support rods 12.
[0027] Thus, the baffle structure of the utility model is installed in the cylinder of the heat exchange equipment, and a heat exchange tube can be arranged in the cylinder, and the heat exchange tube passes through the gap 2 formed between two adjacent support rods 12. During heat exchange, steam is input into the cylinder, and water is input into the heat exchange tube, and the steam passes through the gap 2, thereby heating the water in the heat exchange tube. Since the support rods 12 are arranged in multiple numbers, there are more gaps 2, and the fluid (steam) passes through different gaps 2, so that the heat exchange tube is not easy to vibrate and damage the heat exchange equipment.
[0028] Optionally, the plurality of support rods 12 are parallel to each other, and the distance between two adjacent support rods 12 is equal. Since the plurality of support rods 12 are parallel to each other, and the distance between two adjacent support rods 12 is equal, during installation, the heat exchange tube can be passed through the gap 2, so that one side of the heat exchange tube contacts with one support rod 12, and the other side of the heat exchange tube contacts with another support rod 12, thereby limiting the heat exchange tube.
[0029] In this example, the outer diameter of the support rod 12 is smaller than the distance between two adjacent support rods 12, so that the outer diameter of the support rod 12 is smaller, which is convenient for fixing the support rod 12 on the baffle ring 11, and the gap 2 is larger, which is convenient for limiting the heat exchange tube with a larger diameter within the gap 2, so as to achieve heating of the water in the heat exchange tube. The baffle ring 11 in this example is in a circular ring shape, so that it is easy to be installed in a heat exchange device with a cylindrical barrel.
[0030] Furthermore, the baffle groups 1 are provided in at least two groups, and each group of baffle groups 1 is connected together by a spacing mechanism 3. By providing multiple groups of baffle groups 1, after the heat exchange tube passes through the gaps 2 of different baffle groups 1, the heat exchange tube can be limited from different directions, thereby preventing the heat exchange tube from moving. Different baffle groups 1 play a role in regulating the flow direction and distribution of the fluid. Different baffle groups 1 make the fluid form alternating laminar flow and turbulent flow, thereby improving the heat exchange effect.
[0031] In a preferred embodiment of the utility model, a through hole 111 is provided on the baffle ring 11 of each baffle group 1; the spacing mechanism 3 includes a pull rod 31 and a spacing tube 32, the pull rod 31 passes through the through holes 111 of different baffle groups 1, the spacing tube 32 is sleeved on the pull rod 31, one end of the spacing tube 32 rests on one baffle ring 11, and the other end of the spacing tube 32 rests on another baffle ring 11.
[0032] When connecting, the spacing tube 32 is placed between two adjacent baffle groups 1, and then the pull rod 31 is used to pass through the through hole 111 of one baffle group 1, the spacing tube 32 and the through hole 111 of another baffle group 1 in sequence, so that the spacing tube 32 is located between the two baffle groups 1, and one end of the spacing tube 32 is against a baffle ring 11, and the other end of the spacing tube 32 is against another baffle ring 11, thereby spacing the baffle groups 1, so that the fluid passes through multiple baffle groups 1 to form alternatingly distributed laminar flow and turbulent flow, thereby improving the heat exchange effect.
[0033] Specifically, a plurality of through holes 111 are arranged on the baffle ring 11, and the plurality of through holes 111 are evenly distributed on the baffle ring 11. By providing the plurality of through holes 111, the plurality of baffle groups 1 are spaced apart by the plurality of tie rods 31 and the plurality of distance tubes 32, thereby further improving the firmness.
[0034] In this example, the support rods 12 of two adjacent groups of baffles 11 are oriented in different directions. Specifically, Figure 2 and Figure 3As shown, the baffle group 1 can be two groups, namely, an upper baffle group 1a and a lower baffle group 1b, the angle formed by the support rod 12 of the upper baffle group 1a and the vertical plane is angle A, angle A is 45 degrees, the angle formed by the support rod 12 of the lower baffle group 1b and the vertical plane is angle B, angle B is 135 degrees, and the upper baffle group 1a and the lower baffle group 1b are connected together by a spacing mechanism 3. In this way, by setting the upper baffle group 1a and the lower baffle group 1b, and the angle A is different from the angle B, the heat exchange tube can be limited at multiple angles to prevent the heat exchange tube from shaking.
[0035] In other examples, the support rods 12 of two adjacent groups of baffles 11 are oriented in different directions. Figure 4 and Figure 5 As shown, the deflector group 1 can be four groups, namely the first deflector group 1c, the second deflector group 1d, the third deflector group 1e and the fourth deflector group 1f. The angle formed by the support rod 12 of the first deflector group 1c and the vertical plane is angle C, and the angle C is 45 degrees. The angle formed by the support rod 12 of the second deflector group 1d and the vertical plane is angle D, and the angle D is 135 degrees. The angle formed by the support rod 12 of the third deflector group 1e and the vertical plane is angle E, and the angle E is 45 degrees. The angle formed by the support rod 12 of the fourth deflector group 1f and the vertical plane is angle F, and the angle F is 135 degrees. The first deflector group 1c, the second deflector group 1d, the third deflector group 1e and the fourth deflector group 1f are connected together by a spacing mechanism 3. In this way, by setting the first baffle group 1c, the second baffle group 1d, the third baffle group 1e and the fourth baffle group 1f, and the angles C, D, E and F are all different, the heat exchange tubes can be limited at multiple angles to prevent the heat exchange tubes from shaking.
[0036] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
