DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0029] In view of the problems existing in the prior art, an embodiment of the present invention provides an air distribution structure for an environmentally friendly heating device. Figure 1 and Figure 2As shown, the air distribution structure for environmentally friendly heating equipment includes a first air distribution pipe 3 and a body 1 connected to the first air distribution pipe 3. The side wall of the first air distribution pipe 3 is connected with a second air distribution pipe 5, and the second air distribution pipe 5 extends into the mixing chamber 2. The gas enters the mixing chamber 2 through the first air distribution pipe 3 and the second air distribution pipe 5. The mixing chamber 2 is arranged in the body 1, and the air inlet end of the first air distribution pipe 3 is connected with a blower 4. The setting of the blower 4 can input gas into the first air distribution pipe 3. A gas quantity control mechanism 7 is arranged in the first air distribution pipe 3, and a sensor 6 is arranged on the second air distribution pipe 5. When working, the sensor 6 collects the amount (which can be understood as the quantity or volume) signal of the biomass fuel in the mixing chamber 2 in real time, and controls the start or shut down of the gas quantity control mechanism 7 according to the amount signal, so as to control the amount of gas entering the mixing chamber 2 by adjusting the cross-sectional size of the air duct.

[0030] In one embodiment, Figure 2 As shown, the gas quantity control mechanism 7 includes a blocking plate 75 fixedly arranged in the first air distribution pipe 3, and the blocking plate 75 divides the inner cavity of the first air distribution pipe 3 into two non-connected first and second cavities. It can be understood that the second cavity is on the left side of the blocking plate 75, and the first cavity is on the right side of the blocking plate 75. The blocking plate 75 is provided with a wind hole 76 for connecting the first cavity and the second cavity. The blocking plate 75 is located on the side of the first cavity (which can be understood as the right side) and is fitted with a wind shield 74, which is used to block the wind hole 76. The wind shield 74 is fixedly sleeved outside the first rotating rod 73, and the first rotating rod 73 is connected to the driving end of the first motor 71, and the first motor 71 is used to drive the wind shield 74 to rotate. The first motor 71 is fixedly arranged in the support box 72, and the outer wall of the support box 72 is fixedly connected with a support rod 77, and the free end of the support rod 77 is fixedly connected to the inner wall of the first air distribution pipe 3.

[0031] During operation, the sensor 6 controls the start of the first motor 71 according to the amount of biomass fuel in the mixing chamber 2. The operation of the first motor 71 will cause the wind shield 74 to rotate through the first rotating rod 73. The rotation of the wind shield 74 will change the shielding area of ​​the wind hole 76, thereby changing the cross-sectional size of the air duct, and then adjusting the amount of gas entering the mixing chamber 2, so that the amount of gas entering the mixing chamber 2 can match the amount of biomass fuel in the mixing chamber 2, which can not only ensure the sufficient combustion of the biomass fuel, but also avoid the waste caused by excessive gas.

[0032] In order to enable the wind shield 74 to effectively block the wind hole 76, in one embodiment, the cavity of the wind hole 76 is a semi-disc-shaped structure, such as Figure 2For example, the cavity of the air hole 76 has a first diameter, and the wind shield 74 is a semi-disc-shaped structure, such as Figure 2 In one example, the windshield 74 has a second diameter, the second diameter is larger than the first diameter, the first rotating rod 73 is arranged on the central axis of the windshield 74, the central axis of the windshield 74 coincides with the central axis of the wind hole 76, and the wind hole 76 is arranged to match the windshield 74. Of course, in other examples, the slot cavity of the wind hole 76 and the windshield 74 are not limited to a semi-disc-shaped structure. At the same time, the number of the slot cavity of the wind hole 76 and the windshield 74 is not limited to only one. The number of the slot cavity of the wind hole 76 and the windshield 74 can also be set to different numbers. For example, in one example, there are two wind holes 76, and the two wind holes 76 are symmetrically arranged about the vertical center line of the blocking plate 75. The number of windshield 74 is set to one, and the center of one windshield 74 is set between the two wind holes 76, preferably, in the middle of the two wind holes 76.

[0033] In order to allow the biomass fuel and gas to be fully mixed, in one embodiment, Figure 3 As shown, the air distribution structure for the environmentally friendly heating equipment also includes a mixing and stirring mechanism 9, and the mixing and stirring mechanism 9 is used for mixing biomass fuel and gas. The stirring mechanism 9 includes a mixing and stirring claw 91 and a third rotating rod 92, and the mixing and stirring claw 91 and the third rotating rod 92 are connected to each other, and the mixing and stirring claw 91 is arranged in the mixing chamber 2, and the third rotating rod 92 is movably arranged in the second air distribution pipe 5. During operation, the rotation of the third rotating rod 92 drives the rotation of the mixing and stirring claw 91, thereby stirring and mixing the biomass fuel and the gas, so that the biomass fuel and the gas can be fully mixed. In an example, the number of mixing and stirring claws 91 along the axial direction of the third rotating rod 92 can be set to one, two, three or more. The increase in the number of mixing and stirring claws 91 can increase the area of ​​stirring and mixing, thereby improving the mixing efficiency.

[0034] The rotation of the mixing and stirring mechanism 9 needs to be able to be provided. In order to make the mixing and stirring mechanism 9 work without external energy, and also to reduce production costs, in one embodiment, as Figure 3 , Figure 5 and Figure 4As shown, the air distribution structure for environmentally friendly heating equipment also includes a first linkage mechanism 8, which is used to drive the rotation of the mixing and stirring mechanism 9. The first linkage mechanism 8 includes a blocking tube 81 fixedly arranged in the first air distribution pipe 3, and the blocking tube 81 is fixedly connected to the blocking plate 75. Specifically, the right end of the blocking tube 81 is connected to the left end of the blocking plate 75. The inner cavity of the blocking tube 81 is interconnected with the wind hole 76, and an air outlet 86 is provided on the blocking tube 81. After the gas enters the blocking tube 81 through the wind hole 76, it will enter the second air distribution pipe 5 through the air outlet 86. The air outlet 86 is used for the inner cavity of the blocking tube 81 and the inner cavity of the second air distribution pipe 5 to be interconnected. A blocking tube 87 is fixedly arranged in the blocking tube 81, and the blocking tube 87 divides the inner cavity of the blocking tube 81 into two unconnected cavities, and the two cavities are connected through the tube cavity of the blocking tube 87. A rotating disk 82 is rotatably arranged inside the blocking tube 87, and a plurality of air storage slots 83 are opened on the circumference of the rotating disk 82. The rotating disk 82 is fixedly sleeved outside the second rotating rod 84. A rotating shaft 85 is connected to the lower end of the second rotating rod 84. The rotating shaft 85 is rotatably arranged on the inner bottom wall of the blocking tube 81. The upper end of the second rotating rod 84 is connected to the third rotating rod 92.

[0035] In one embodiment, Figure 5 As shown, a plurality of the air storage slots 83 are arranged in an equidistant ring shape, and there is an angle between the slot cavity of the air storage slot 83 and the vertical line, and the size of the angle is between 20°-80°. This arrangement can ensure the leftward movement of the gas, and can push the rotating disk 82 to rotate through the air storage slots 83.

[0036] In this embodiment, the rotational power of the rotating disk 82 is provided by the gas passing through the blocking tube 87. Specifically, when the gas moves from right to left, it will enter the air storage tank 83. Since the air storage tank 83 is inclined, the rotating disk 82 will be pushed by the air storage tank 83 to rotate counterclockwise. Figure 5 For example, the rotation of the rotating disk 82 will cause the second rotating rod 84 to rotate, and the rotation of the second rotating rod 84 will cause the mixing and stirring claw 91 to rotate through the third rotating rod 92. The rotation of the mixing and stirring claw 91 can achieve the mixing of biomass fuel and gas. It can be seen that the structural design in the present invention is reasonable, and the rotation of the mixing and stirring mechanism 9 does not require an external power source. This can reduce production costs on the one hand, and improve the linkage performance of the equipment on the other hand, that is, when there is gas passing through the blocking tube 87 and being transported into the mixing chamber 2, the mixing and stirring mechanism 9 will be driven to start working.

[0037] In one embodiment, Figure 6 , Figure 7 and Figure 8As shown, the air distribution structure for environmentally friendly heating equipment also includes a flow rate control mechanism 10 disposed in the second air distribution pipe 5, and the flow rate control mechanism 10 is used to control the gas flow rate entering the mixing chamber 2 to remain consistent. The flow rate control mechanism 10 includes a rotating ring 101 movably sleeved outside the third rotating rod 92, and the rotating ring 101 is provided with a plurality of moving holes 102, and a moving column 103 is movably arranged in the moving hole 102, and the moving hole 102 is an arc-shaped structure. The setting of this structure can make the moving column 103 move along the cavity of the moving hole 102 to move closer to or away from the center of the rotating ring 101. The lower end of the movable column 103 is connected with a rotating blade 106, and a plurality of the rotating blades 106 surround an air outlet 109 of adjustable size. In one example, the cavity diameter of the air outlet 109 is smaller than the inner ring diameter of the rotating ring 101, and the third rotating rod 92 is arranged in the air outlet 109. In this way, when the air volume is constant, the wind speed passing through the flow rate control mechanism 10 can be adjusted by changing the aperture size of the air outlet 109, and the wind speed passing through the flow rate control mechanism 10 can be adjusted to be consistent by changing the aperture size of the air outlet 109. A first gear 1010 is fixedly sleeved outside the circumference of the rotating ring 101. The upper end surface of the rotating ring 101 is provided with a sliding groove 108 in an annular structure, and a sliding rod 104 is slidably arranged in the sliding groove 108. The upper end of the sliding rod 104 is fixedly connected to the inner top wall of the support tube 105. The sliding rod 104 and the sliding groove 108 are matched with each other. The arrangement of the sliding rod 104 and the sliding groove 108 can make the rotating ring 101 always rotate horizontally in the horizontal direction. The support tube 105 is fixedly arranged on the inner side wall of the second air distribution pipe 5.

[0038] The setting of the flow rate control mechanism 10 in this embodiment can adjust the wind speed through the flow rate control mechanism 10 to be consistent by changing the aperture size of the air outlet hole 109. Specifically, when the air volume passing through the gas volume control mechanism 7 decreases, the aperture of the air outlet hole 109 will become smaller, and when the air volume passing through the gas volume control mechanism 7 increases, the aperture of the air outlet hole 109 will become larger. In this embodiment, the structure of the flow rate control mechanism 10 is reasonably designed, and the aperture of the air outlet hole 109 will change with the change of the air volume, so as to ensure that no matter how much air volume passes through the gas volume control mechanism 7, the gas flow rate through the flow rate control mechanism 10 can be guaranteed to be consistent.

[0039] In one embodiment, Figure 7As shown, the air distribution structure for the environmentally friendly heating equipment also includes a rotation control mechanism 11, and the rotation control mechanism 11 is used to drive the rotating ring 101 to rotate. The rotation control mechanism 11 includes a second motor 111, and the second motor 111 is fixedly arranged on the inner bottom wall of the support cylinder 105. The driving end of the second motor 111 is connected to the fourth rotating rod 112, and the upper end of the fourth rotating rod 112 is fixedly connected to the second gear 113, and the second gear 113 is meshed with the first gear 1010.

[0040] When working, the second motor 111 is started, and the second gear 113 is rotated through the fourth rotating rod 112. The rotation of the second gear 113 causes the rotating ring 101 to rotate through the first gear 1010. The rotation of the rotating ring 101 causes the moving column 103 to move in the moving hole 102. The movement of the moving column 103 causes the rotating blades 106 to move. The movement of several rotating blades 106 changes the size of the air outlet 109. It should be understood that the rotation of the rotating ring 101 will cause the moving column 103 to move against the hole wall of the moving hole 102.

[0041] In order to guide and support the movement of the rotating blade 106, and at the same time, when the contact with the hole wall of the moving hole 102 is lost, the rotating blade 106 can automatically achieve the reset effect. In one embodiment, Fig. 9 As shown, the flow rate control mechanism 10 also includes an initial position reset component 107, which is used for guiding and supporting the movement of the rotating blade 106, and for resetting the rotating blade 106. The initial position reset component 107 includes an arc plate 1071, which is fixedly arranged on the inner bottom wall of the support cylinder 105, and a first fixed block 1072 is fixedly connected to the side wall of the arc plate 1071, and a reset spring 1073 is fixedly connected to the side wall of the first fixed block 1072, and the free end of the reset spring 1073 is fixedly connected to the second fixed block 1074, and the second fixed block 1074 is fixedly arranged on the rotating blade 106.

[0042] During operation, the movement of the movable column 103 will cause the rotating fan blades 106 to move relative to the arc plate 1071, and the movement of the rotating fan blades 106 will cause the second fixed block 1074 to move closer to or away from the first fixed block 1072. During this movement, the reset spring 1073 between the second fixed block 1074 and the first fixed block 1072 is stretched or compressed. In this way, when the movable column 103 loses the resistance of the movable hole 102, under the action of the reset spring 1073, the rotating fan blades 106 can achieve the effect of automatic reset.

[0043] It is worth noting that, in one example, the second fixing block 1074 and the arc plate 1071 are slidably arranged.

[0044] In order to improve the high efficiency performance of the device and reduce the production cost of the device, in one embodiment, Fig.10 and Fig.11 As shown, the air distribution structure for environmentally friendly heating equipment also includes a second linkage mechanism 12, and the second linkage mechanism 12 is used for the linkage of the rotating ring 101 and the first rotating rod 73. The second linkage mechanism 12 includes a third gear 121, and the third gear 121 is meshed with the first gear 1010. A fifth rotating rod 122 is fixedly connected to the lower end surface of the third gear 121, and the fifth rotating rod 122 is movably plugged on the bottom plate of the support cylinder 105. The lower end of the fifth rotating rod 122 extends into the first air distribution pipe 3, and the lower end of the fifth rotating rod 122 is fixedly connected to the first bevel gear 123, and the first bevel gear 123 is meshed with the second bevel gear 124. The second bevel gear 124 is fixedly sleeved outside the first rotating rod 73.

[0045] During operation, as the first rotating rod 73 rotates, the second bevel gear 124 will rotate, and the movement of the second bevel gear 124 will rotate the third gear 121 through the first bevel gear 123 and the fifth rotating rod 122, and the rotation of the third gear 121 will rotate the rotating ring 101 through the first gear 1010, so that the aperture of the air outlet 109 can be adjusted. The device structure in the present invention is reasonably designed, and the second linkage mechanism 12 is set to link the aperture size adjustment of the air outlet 109 with the cross-sectional size adjustment of the air outlet 76, so that the high efficiency performance of the device can be improved. Specifically, when the cross-sectional area of ​​the air outlet 76 is reduced, the aperture of the air outlet 109 becomes smaller, and when the cross-sectional area of ​​the air outlet 76 is increased, the aperture of the air outlet 109 becomes larger.

[0046] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
