[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below by specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0021] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection (i.e., non-detachable connection) includes but is not limited to conventional fixed connection methods such as folding connection, rivet connection, bonding connection, and welding connection. The detachable connection includes but is not limited to conventional detachable methods such as threaded connection, snap connection, pin connection, and hinge connection. When the specific connection method is not clearly defined, it is assumed that at least one connection method can always be found in the existing connection methods to achieve the function. Those skilled in the art can choose according to their needs. For example: welding connection is selected for fixed connection, and hinge connection is selected for detachable connection.
[0022] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] Embodiment 1, combination Figure 1-Figure 3The present embodiment is described. A drying waste heat recovery system of the present embodiment comprises a frame 1, an outer drum 2, an inner cage 3, a suction bellows 4 and an electromagnetic heater 6. The outer drum 2 and the inner cage 3 are rotatably arranged in the frame 1. The inner cage 3 is arranged inside the outer drum 2. The suction bellows 4 and the electromagnetic heater 6 are mounted on the upper end surface of the frame 1. An air inlet 5 is arranged on the frame 1. The air inlet 5 is connected to the input end of the electromagnetic heater 6 through an air inlet channel 12. The output end of the electromagnetic heater 6 is connected to the input end of the suction bellows 4. The output end of the suction bellows 4 is connected to a hot air channel 9. The output end of the hot air channel 9 is arranged in the inner cage 3. A plurality of honeycomb holes 10 are processed on the inner cage 3. The honeycomb holes 10 are connected to the exhaust channel 13 through the outer drum interlayer 7. The exhaust channel 13 is connected to the suction and exhaust air ports 14. The suction and exhaust air ports 14 are arranged on the frame 1.
[0024] During drying, the suction blower 4 and the electromagnetic heater 6 on the frame 1 are turned on. After the suction blower 4 is turned on, negative pressure is formed in the air inlet channel 12, and the normal temperature natural wind outside the equipment is sucked into the air inlet channel 12 through the air inlet 5. The air inlet channel 12 is heated by the electromagnetic heater 6, and then enters the hot air channel 9 through the output port of the suction blower 4, and finally enters the inner rotating cage 3 through the hot air channel 9 to dry the textiles in the inner rotating cage 3;
[0025] The dried wind passes through the honeycomb holes 10 on the inner rotating cage 3 and the outer drum interlayer 7 into the exhaust channel 13. The waste heat in the exhaust channel 13 exchanges heat with the natural wind at room temperature in the air inlet channel 12 to increase the temperature in the air inlet channel 12. The waste heat after heat exchange passes through the filter 8 to filter out the remaining fluff in the waste heat, and then is output to the exhaust pipe 17 through the exhaust port 14. The exhaust fan 18 is installed at the exhaust port 14. The exhaust port 14 is connected to the exhaust pipe 17 through the exhaust fan 18. When the drying is in progress, the exhaust fan 18 is used to dry the waste heat. 18 starts exhausting air to form a negative pressure in the exhaust passage 13. Under the action of the exhaust fan 18, the waste heat wind hangs the fluff on the filter 8 by sucking and exhausting air upward. When the drying work is completed, the exhaust fan 18 reverses to blow the outside air into the exhaust passage 13. While cooling the exhaust passage 13, the fluff on the filter 8 is blown off onto the fluff collector 11. When the fluff on the filter 8 accumulates a certain weight, it can also fall onto the fluff collector 11 under the action of its own weight, and there is no need to clean it by itself.
[0026] After exchanging heat with the waste heat air in the exhaust channel 13, the temperature in the air inlet channel 12 increases, and the temperature of the natural wind entering the electromagnetic heater 6 is higher than that of conventional natural wind, which reduces the heat energy consumption of the electromagnetic collector 6. Most of the heat of the waste heat air is also fully utilized, and a large amount of waste heat will not be lost.
[0027] A plurality of inner cage parabolic ribs 15 are evenly distributed on the inner circumference of the inner cage 3. The inner cage parabolic ribs 15 are "V"-shaped parabolic ribs. The inner cage parabolic ribs 15 have the functions of forward rotation parabolic, reverse rotation spiral discharging or reverse rotation parabolic, forward spiral discharging. A storage door 16 is also slidably provided on the front of the frame 1. The storage door 16 is provided with a plurality of sliders. A slideway is correspondingly provided on the frame 1. The storage door 16 slides up and down in the slideway through the sliders.
[0028] This embodiment is only an exemplary description of this patent and does not limit its protection scope. Those skilled in the art may also make partial changes to it, as long as they do not exceed the spirit of this patent, they are all within the protection scope of this patent.
