DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and other obvious variations can be thought of by those skilled in the art.

[0022] Referring to Figures 1-4As shown in the figure, a boiler waste heat conversion device includes a heat exchange box 1. A first arc-shaped groove 101 is penetrated and opened at the top end of the heat exchange box 1. A fixed rod 102 is fixedly connected to the center of the bottom end of the inner cavity of the heat exchange box 1. A fixing plate 103 is fixedly connected to the outer surface of the fixed rod 102. A second arc-shaped groove 104 is opened at the corresponding position between the bottom end of the inner cavity of the heat exchange box 1 and the first arc-shaped groove 101. The top end of the left fixing plate 103 is fixedly connected to a first arc-shaped plate 105. The fixing plate 103 divides the inner cavity of the heat exchange box 1 into a heating cavity 106 and a gas storage cavity 107. An accommodation groove 108 is opened inside the first arc-shaped plate 105;

[0023] A connecting plate 2 is rotatably connected to the outer surface of the fixed rod 102. The top end of the connecting plate 2 is fixedly connected to a second arc-shaped plate 201. The second arc-shaped plate 201 is slidably connected to the accommodation groove 108. The bottom end of the connecting plate 2 is fixedly connected to an adapter rod 202. The adapter rod 202 is slidably connected to the inside of the second arc-shaped groove 104. A main shaft 203 is rotatably connected to the center of the bottom end of the heat exchange box 1;

[0024] The angular rotation range of the second arc-shaped plate 201 is from 0° to 90°. When the volume of the high-temperature waste gas is too small, the rotation angle of the second arc-shaped plate 201 is 0°. At this time, the volume of the gas storage cavity 107 is the smallest, and the movement space of the high-temperature waste gas molecules is limited, avoiding excessive energy consumption and shortening the heating time of the water in the heating cavity 106. When the volume of the high-temperature waste gas is too large, when the rotation angle of the second arc-shaped plate 201 is 90°, at this time, the volume of the gas storage cavity 107 is the largest. Since there are too many high-temperature waste gas molecules, even if the space is large, the high-temperature waste gas molecules have no extra space to move, and only release heat to heat the water inside the heating cavity 106, reducing its own volume and shortening the heating time of the water inside the heating cavity 106;

[0025] A connecting rod 204 is fixedly connected to the outer surface of the main shaft 203. The other end of the connecting rod 204 is fixedly connected to the top end of the connecting plate 2. The outer surface of the connecting rod 204 is slidably connected to the first arc-shaped groove 101. An air delivery pipe 205 is fixedly connected to the bottom end of the heat exchange box 1. The air delivery pipe 205 is communicated with the gas storage cavity 107. A water pump 3 is fixedly installed at the center of the top end of the heat exchange box 1. A water inlet pipe 301 is fixedly connected to the input end of the water pump 3. A water outlet pipe 302 is fixedly connected to the output end of the water pump 3. The water outlet pipe 302 is communicated with the heating cavity 106;

[0026] Embodiment 1

[0027] The water pump 3 transports the external water source to the heating chamber 106 through the water outlet pipe 302, connects the gas transmission pipe 205 with the boiler, rotates the connecting rod 204, adjusts the position of the connecting rod 204 in the first arc-shaped groove 101, inserts the second arc-shaped plate 201 into the receiving groove 108 of the first arc-shaped plate 105, and reduces the volume of the gas storage chamber 107. When the high-temperature waste gas molecules rapidly discharge heat, they will heat the water in the heating chamber 106, shortening the heating time of the water.

[0028] When the present utility model is in use, it specifically includes the following steps:

[0029] Step 1: Add water to the heating chamber 106 through the water pump 3;

[0030] Step 2: Connect the gas transmission pipe 205 with the boiler;

[0031] Step 3: Rotate the connecting rod 204 through the high-temperature waste gas, insert the second arc-shaped plate 201 into the receiving groove 108, and reduce the volume of the heating chamber 106;

[0032] Step 4: Heat the water in the heating chamber 106 with the high-temperature waste gas.
