[0001] The utility model relates to the technical field of windows, in particular to a window structure and a heat exchange air duct using the window structure. Background Art

[0002] At present, the heat exchange device used for waste heat recovery of textile setting machines is a multi-chamber structure, with a heat exchange tube in the chamber, outside air entering the chamber, high-temperature exhaust gas passing through the heat exchange tube, and the air in the chamber is heated by the heat exchange tube and then discharged for use. Since the air environment in the setting workshop is very bad, the air contains a large amount of exhaust gas and dust. These air with exhaust gas and dust will flow into the chamber of the heat exchange device. After a period of use, a large amount of impurities will accumulate in the chamber of the heat exchange device, and the outer wall of the heat exchange tube will also be sticky with impurities, affecting the heat exchange efficiency. Therefore, it is necessary to regularly check the situation in the chamber and take corresponding measures. At present, an opening is set on the outer wall of the chamber, and a cover plate is connected to the opening. The situation in the chamber is observed by removing the cover plate. The cover plate is threadedly connected to the outer wall of the chamber. When disassembling, the cover plate needs to be completely removed, and when installing, it also needs to be installed behind the hole. Therefore, disassembly and assembly are relatively inconvenient, and there are shortcomings. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solution of the utility model is further described below through embodiments and in conjunction with the accompanying drawings.

[0028] Embodiment 1:

[0029] like Figure 1 , Figure 2 As shown, a window structure includes a ring sleeve 2, a cover plate 3, and a second fixing plate 5. The ring sleeve 2 is an annular thin-walled structure. The ring sleeve 2 is an elliptical or circular structure. The ring sleeve 2 is axially penetrated and has openings on both sides of the axial direction. The ring sleeve 2 is installed on the outside of the container body 1. The container body 1 is the chamber body of the waste heat recovery device of the setting machine. The outer wall of the container body 1 is provided with an opening 11. The opening 11 is set at different positions of the container body 1 that need to be observed. The ring sleeve 2 is welded and fixed to the outer wall of the container body 1. The axial inner side of the ring sleeve 2 (i.e. Figure 2 The opening (on the left side of the orientation shown) is connected to the opening 11.

[0030] like Figure 2 As shown, the cover plate 3 is located on the outside of the ring sleeve 2 in the axial direction. The cover plate 3 is a plate-like structure. The cover plate 3 includes an end plate. The end plate of the cover plate 3 can cover the opening of the ring sleeve 2. The cover plate 3 also includes a ring plate 31 that extends and protrudes along the end surface of the end plate of the cover plate 3 toward the axial inner side of the ring sleeve 2. The shape of the ring plate 31 matches the shape of the circumferential outer wall of the ring sleeve 2. The inner periphery of the ring plate 31 can be inserted into the outer wall of the ring sleeve 2. When the end surface of the cover plate 3 covers the ring sleeve 2, the ring plate 31 plays a guiding role and prevents the cover plate 3 from slipping in position, which causes the opening of the ring sleeve 2 to be unable to be completely closed.

[0031] like Figure 2 As shown, a pressure rod assembly 4 is connected to the outside of the cover plate 3, and the pressure rod assembly 4 includes a pressure rod 41. The pressure rod 41 is a "7"-shaped narrow plate-like structure. The pressure rod 41 includes a pressure rod body 411 and an extension rod 412. The pressure rod body 411 is a long strip. The pressure rod body 411 is located axially outside the cover plate 3 (i.e. Figure 2 The extension rod 412 extends along the upper end of the pressure rod body 411 toward the side close to the cover plate 3 (i.e. Figure 2 The cover plate 3 extends vertically from the axial inner side of the annular sleeve 2 to the radial outer side of the annular sleeve 2 ( Figure 2 The position shown is above the ring sleeve 2).

[0032] like Figure 2 , Figure 3 As shown, the second fixing plate 5 is welded to the radial outer side of the ring sleeve 2. Figure 3 As shown, the second fixing plates 5 are arranged in pairs, the extension rod 412 is located between the second fixing plates 5 on both sides, and the second bolts 9 are passed between the second fixing plates 5 on both sides. The second bolts 9 pass through the extension rod 412, and the extension rod 412 can rotate along the axis of the second bolt 9, thereby realizing the hinge connection between the pressure rod 41 and the second fixing plates 5.

[0033] like Figure 4 As shown, first fixing plates 42 are provided on both sides of the pressure rod body 411, the first fixing plates 42 are fixedly connected to the cover plate 3 by welding, and the first fixing plates 42 and the pressure rod body 411 are fixedly connected by first bolts 8, and the first bolts 8 pass through the first fixing plates 42 and the pressure rod body 411 along the radial direction of the cover plate 3.

[0034] like Figure 2 As shown, when the extension rod 412 rotates along the hinge point, driving the entire pressure rod 41 to rotate, the inner hole wall of the pressure rod body 411 abuts against the outer wall of the first bolt 8, driving the first fixing plate 42 and the cover plate 3 to rotate together, so that the axial inner end face of the end plate of the cover plate 3 is fitted or separated from the axial outer end face of the ring sleeve 2, so that the cover plate 3 closes or opens the axial outer opening of the ring sleeve 2.

[0035] like Figure 2As shown, the first fixing plate 42 is located near the center of the cover plate 3, so the point of application of the force applied by the pressure rod body 411 is located at the center of the cover plate 3, so that when the outer peripheral end face of the cover plate 3 fits the end face of the ring sleeve 2, the fitting force is relatively uniform, and a sealing effect can be formed on the end face of the ring sleeve 2 after applying a suitable fitting force, preventing excessive extrusion between the cover plate 3 and the ring sleeve 2 to cause deformation and affect the sealing effect.

[0036] like Figure 2 As shown, the pressure rod 41 further includes a connecting block 413 on a side away from the hinge point, and the connecting block 413 is located on a side of the pressure rod body 411 away from the extension rod 412. Figure 2 , Figure 4 The connecting block 413 is a cylindrical structure, and the axial direction of the connecting block 413 is parallel to the axial direction of the cover plate 3. The connecting block 413 is fixed to the pressure rod body 411 by welding.

[0037] like Figure 2 As shown, the connecting block 413 is connected to the knob assembly 7, and the knob assembly 7 includes a stop block 72 and an insert rod 73 located on the inner side of the stop block 72. The insert rod 73 is a threaded rod, and the outer diameter of the insert rod 73 matches the inner hole diameter of the connecting block 413. The insert rod 73 passes through the connecting block 413 and extends axially inwardly of the cover plate 3. An insert sleeve 6 is provided on one side of the extending direction of the insert rod 73. The insert sleeve 6 is welded and fixed to the outer wall of the container body 1, and the insert rod 73 is threadedly connected and inserted into the insert sleeve 6.

[0038] like Figure 2 As shown, the stop block 72 is located on the side of the connecting block 413 away from the cover plate 3, the outer diameter of the stop block 72 is larger than the outer diameter of the insertion rod 73, and a knob head 71 is provided on the side of the stop block 72 away from the insertion rod 73. The knob head 71 is a circular ring structure, and the knob head 71 is arranged to facilitate the operator to operate the knob.

[0039] Embodiment 2:

[0040] like Figure 5 As shown, a heat exchange air cylinder includes the window structure in the embodiment.

[0041] like Figure 6 , Figure 7 As shown, the heat exchange duct includes a bottom frame 101, which is a frame structure, and a cavity is provided in the bottom frame 101. The top of the bottom frame 101 is open, and the bottom of the bottom frame 101 is closed. The bottom frame 101 includes a first side wall 1011 located at the side, and the first side wall 1011 surrounds the bottom frame 101. Figure 7 As shown, a partition 1012 is installed between the bottom frames 101 on both sides of one of the opposite sides. Figure 5 , Figure 7 The partition 1012 is a plate-like structure, with a bulge formed on the outer periphery of the partition 1012 and a depression formed on the inner side. The partition 1012 divides the top opening of the bottom frame 101 into two openings.

[0042] like Figure 5 As shown, air ducts are installed at the upper ends of the two openings. The air ducts are cylindrical structures and include a cover body 103 and a cover top 102 located at the upper end of the cover body 103. The bottom of the cover body 103 is fixed to the upper end surface of the first side wall 1011 and the outer peripheral protrusions of the partition 1012 respectively.

[0043] like Figure 5 As shown, the cover top 102 and the bottom frame 101 are respectively located on both sides of the cover body 103, and the cover body 103 is connected from top to bottom. Flat plates are arranged on the upper and lower sides of the cover body 103 to seal the upper and lower sides of the cover body 103, so that the cover body 103 is not connected with the cover top 102 and the bottom frame 101, and a plurality of through pipes 105 are installed between the two side plates. The through pipes 105 are axially connected, and the two ends of the through pipes 105 are respectively connected with the cover top 102 and the bottom frame 101, and the two cover bodies 103 are connected through the air duct 104.

[0044] like Figure 5 As shown, the cover top 102 includes a first outlet 1021 at the top and a second outlet 1022 at the connection with the cover body 103. The high-temperature exhaust gas enters from the first outlet 1021 of the cover top 102 on one side, and enters the bottom frame 101 along the through pipe 105 in the cover body 103 on the side, and then enters from the through pipe 105 at the bottom of the cover body 103 on the other side, and finally enters the cover top 102 on the side and passes out upward. At the same time, the cover bodies 103 on both sides are respectively provided with an air inlet 106 and an air outlet 107. The air inlet 106 takes in air, and the air enters the cover body 103 on the other side along the air duct 104 through the cover body 103 on one side, and finally flows out from the air outlet 107. When the high-temperature exhaust gas flows through the through pipe 105, the wall of the through pipe 105 is heated, and the air flowing on the outer wall of the through pipe 105 is also heated. The heated air is used after passing out, thereby realizing the recovery of heat in the high-temperature exhaust gas and achieving the effect of energy saving and emission reduction.

[0045] Since the exhaust gas contains a large amount of impurities, the bottom frame 101 and the top cover 102 need to be cleaned regularly, so an inspection port needs to be provided to regularly check the internal conditions.

[0046] like Figure 5 , Figure 8 As shown, the first side wall 1011 is provided with a first window hole 10111, and the window structure in the first embodiment is installed at the first window hole 10111 to facilitate observation.

[0047] The cover top 102 includes a second side wall 1023 located at the side, and the second side wall 1023 includes a second window hole 10231. The window structure in the first embodiment is installed at the second window hole 10231 to facilitate observation.

[0048] like Figure 6 , Figure 7 As shown, corner ribs 1013 are disposed between adjacent first side walls 1011 and between the first side wall 1011 and the partition 1012 to improve the structural stability of the bottom frame 101 .

[0049] Since the high-temperature exhaust gas entering the through pipe 105 contains water vapor, the water vapor condenses on the inner wall of the through pipe 105 when it is cooled to form liquid water, and the liquid water flows into the bottom frame 101. Therefore, a closable drainage hole is provided at the bottom of the first side wall 1011 to regularly drain the water in the bottom frame 101.

[0050] In order to improve the heat exchange efficiency of the heat exchange duct, an insulation layer is wrapped around the outer surface of the heat exchange duct, namely the bottom frame 101, the top cover 102, and the outer wall of the cover body 103, to reduce the heat loss caused by heat exchange between the outer surface of the heat exchange duct and the outside.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
