Figure 2 is a top view of the first embodiment of the utility model, Figure 3 It is a partial structural schematic diagram of the first embodiment of the utility model.

[0022] The utility model provides a waste heat recovery device for a feed dryer, comprising an exhaust pipe 101 and a recovery mechanism, wherein the recovery mechanism comprises a box body 102, a delivery pipe 104, a chimney pipe 105, an air intake pipe 107, a plurality of heating components, an adjustment component and a collection component, each group of the heating components comprises a heat conducting rod 108 and a heating plate 109, the adjustment component comprises a baffle 110, a movable plate 111, two sealing pads 112 and a movable part, the movable part comprises a mounting frame 113, a motor 114 and a threaded rod 115, and the collection component comprises a collection frame 116 and a drain pipe 117. The above-mentioned scheme solves the problem in the prior art that when the humidity in the workshop is normal, the hot air exhausted by the dryer cannot be utilized, resulting in low practicality.

[0023] According to the present specific embodiment, one end of the exhaust pipe 101 is fixedly connected to the dryer 118, the other end of the exhaust pipe 101 is fixedly connected to the box 102, the delivery pipe 104 is fixedly connected to the box 102 and is located at one end of the box 102, the chimney pipe 105 is fixedly connected to the box 102 and is located at one end of the box 102 away from the delivery pipe 104, the air intake pipe 107 is fixedly connected to the dryer 118 and is fitted with the chimney pipe 105, multiple groups of heating components are arranged inside the air intake pipe 107, the heating plate 109 is arranged inside the air intake pipe 107, one end of the heat conducting rod 108 is fixedly connected to the heating plate 109, the other end of the heat conducting rod 108 respectively penetrates the air intake pipe 107 and the chimney pipe 105, and is inserted into the inside of the chimney pipe 105, and the regulating component is arranged inside the box 102. The collecting component is arranged below the chimney pipe 105. When it is used specifically, when the humidity in the workshop is high, the chimney pipe 105 is blocked by the regulating component, so that the hot air discharged from the exhaust pipe 101 is transported to the delivery pipe 104 through the box body 102, and then transported to the workshop through the delivery pipe 104, so as to adjust the humidity in the workshop. When the humidity in the workshop is normal, the delivery pipe 104 is blocked by the regulating component, so that the hot air discharged from the exhaust pipe 101 is transported to the chimney pipe 105 through the box body 102. When the hot air passes through the heat conducting rod 108, the heat is transferred to the heat conducting rod 108, and the heat conducting rod 108 transfers the heat to the heating plate 109. The air passing through the intake pipe 107 and entering the dryer 118 is preheated by the heating plate 109, so as to reduce the heat loss of the dryer 118.

[0024] Among them, the moving part is arranged on the upper surface of the box body 102, the baffle 110 is arranged inside the box body 102, the moving plate 111 passes through the box body 102 and is slidably connected to the box body 102, one end of the moving plate 111 is threadedly matched with the moving part, and the other end of the moving plate 111 is fixedly connected to the baffle 110, and the two sealing gaskets 112 are symmetrically arranged on both sides of the baffle 110. When it is used specifically, the moving part drives the moving plate 111 to move left or right, the moving plate 111 drives the baffle 110 to move, and the baffle 110 drives the two sealing gaskets 112 to move, thereby blocking the chimney pipe 105 or the delivery pipe 104.

[0025] Secondly, the mounting frame 113 is fixedly connected to the upper surface of the box body 102, the motor 114 is fixedly connected to one end of the mounting frame 113, the threaded rod 115 passes through the movable plate 111, one end of the threaded rod 115 is rotatably connected to the mounting frame 113, and the other end of the threaded rod 115 is fixedly connected to the output end of the motor 114.

[0026] At the same time, the collecting frame 116 passes through the chimney pipe 105 and is fixedly connected to the chimney pipe 105. The drain pipe 117 is fixedly connected to one end of the collecting frame 116. During specific use, when the hot air transfers heat to the heat conducting rod 108, the hot air will produce water droplets due to the cooling. The water droplets flow along the chimney pipe 105 into the collecting frame 116 and are discharged through the drain pipe 117, so as to prevent the water droplets from flowing back into the dryer 118.

[0027] In addition, the chimney pipe 105 has a rectangular groove 106, and the box body 102 has a slide groove 103 adapted to the movable plate 111. When in use, water droplets flow into the collecting frame 116 through the rectangular groove 106, and the threaded rod 115 rotates to make the movable plate 111 slide in the slide groove 103.

[0028] When using the waste heat recovery device of a feed dryer according to the present embodiment, when the humidity in the workshop is high, the motor 114 is started, and the output end of the motor 114 drives the threaded rod 115 to rotate, so that the movable plate 111 moves to the left, and the movable plate 111 drives the baffle 110 to move to the left, so that the sealing gasket 112 on the left blocks the chimney pipe 105, so that the hot air discharged from the exhaust pipe 101 is transported to the delivery pipe 104 through the box body 102, and then transported to the workshop through the delivery pipe 104, so as to adjust the humidity in the workshop. When the humidity in the workshop is normal, the motor 114 is reversed, so that the movable plate 111 moves to the right, and the movable plate 111 drives the baffle 110 to move to the right, so that the sealing gasket 112 on the right side blocks the delivery pipe 104, so that the hot air discharged from the exhaust pipe 101 is transported to the chimney pipe 105 through the box body 102, and when the hot air passes through the heat-conducting rod 108, the heat is transferred to the heat-conducting rod 108, and the heat-conducting rod 108 transfers the heat to the heating plate 109, and the air passing through the intake pipe 107 and entering the dryer 118 is preheated by the heating plate 109, thereby reducing the heat loss of the dryer 118. This method can effectively solve the problem in the prior art that when the humidity in the workshop is normal, the hot air discharged from the dryer cannot be utilized, resulting in low practicality.
