DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides the following technical solutions: a cloth drying device, comprising a shell, a first cloth roller 3, and a second cloth roller 4, wherein the first cloth roller 3 is symmetrically arranged on both sides of the shell, and the second cloth roller 4 is equidistantly arranged in the shell, and a drying device is arranged in the shell, and the drying device comprises a drying cover 5, an electric heating fin 6 located in the drying cover 5, a heat exchange cover 7, a heat exchange copper tube 8 located in the heat exchange cover 7, and an air cover 9, wherein the drying cover 5 and the heat exchange cover 7 are alternately arranged between the second cloth roller 4 in sequence, and the air cover 9 is arranged at the top of the shell, and the air cover 9 is connected to the inner cavity of the shell, one end of the heat exchange copper tube 8 is connected to the air cover 9, and an air outlet slot 10 is opened on the side wall of the shell, and the other end of the heat exchange copper tube 8 is connected to the air outlet slot 10.

[0018] In the above structure, a fan is arranged at the notch of the air outlet slot 10; a cloth winder is arranged on the side of the shell away from the air outlet slot 10; an electrical control cabinet is arranged near the shell, and the electric heating fins 6, the fan and the cloth winder are connected to the electrical control cabinet through wires. When the electric heating fins 6 are powered on for heating, the temperature of the surface of the drying hood 5 will be increased, thereby heating the moisture in the fabric; when the fan is powered on, the air outlet slot 10 is in a negative pressure state, and the hot and humid air in the shell passes through the wind hood 9 and the heat exchange copper tube 8 in turn, and is finally discharged from the shell from the air outlet slot 10; the heat exchange copper tube 8 quickly absorbs the heat in the hot and humid air, and the heat is then transferred back to the shell by the heat exchange hood 7. By adopting a heat cycle structure, the temperature in the shell is maintained at a relatively high temperature.

[0019] In this embodiment, preheating fins 11 are disposed on the outer wall of the air outlet slot 10 .

[0020] With the above structure, the fan is powered on and running, and the air outlet slot 10 is in a negative pressure state. The hot and humid air in the shell passes through the wind cover 9 and the heat exchange copper tube 8 in sequence and is finally discharged from the shell through the air outlet slot 10. The air outlet slot 10 absorbs the waste heat in the air (specifically the hot and humid air after passing through the heat exchange copper tube 8) and returns it to the shell through the waste heat fins. The waste heat is used to heat the fabric that has just entered the shell, thereby improving the heat cycle efficiency and reducing the heat discharged outside the shell, thereby avoiding the environment in the factory from heating up.

[0021] In this embodiment, preferably, two heat exchange copper tubes 8 are arranged in the heat exchange cover 7. The above setting is not limiting, and the number of the heat exchange copper tubes 8 can also be three.

[0022] With the above structure, the number of the heat exchange copper tubes 8 is determined according to the moisture content of the fabric. Too many heat exchange copper tubes 8 will only increase the cost meaninglessly and will not significantly improve the efficiency of the heat cycle.

[0023] In this embodiment, the air outlet slot 10 is L-shaped, and the long side of the air outlet slot 10 is disposed adjacent to the second cloth roller 4 .

[0024] With the above structure, more waste heat can be recovered into the shell.

[0025] In this embodiment, the heat exchange cover 7 is filled with heat transfer oil.

[0026] With the above structure, the heat transfer oil is used to quickly absorb the heat exchanged by the heat exchange copper tube 8 and transfer it to the heat exchange cover 7. On the other hand, it can be used as a heat insulation material to achieve the technical purpose of maintaining a constant temperature in the shell.

[0027] In this embodiment, two groups of the heat exchange cover 7 and the drying cover 5 are provided.

[0028] In this embodiment, the shell includes a base body 1 and a top cover 2 , the heat exchange cover 7 is arranged on the bottom wall of the top cover 2 , the heat exchange cover 7 is arranged on the top wall of the top cover 2 , and the drying cover 5 is arranged on the bottom wall of the base body 1 .

[0029] Assembly steps:

[0030] 1. Install the electric heating fins 6 on the shell, and connect the drying cover 5 to the shell by bolts; install the heat exchanger in the heat exchange cover 7 through the bracket, add 3 / 4 of heat transfer oil into the heat exchange cover 7, and then connect the heat exchange cover 7 to the bottom wall of the top cover 2 by bolts;

[0031] 2. Install the first cloth roller 3 and the second cloth roller 4 on the base 1;

[0032] 3. Pass the fabric through the first fabric roller 3, the second fabric roller 4 and the fabric winding machine in sequence;

[0033] 4. Install the air cover 9 onto the top cover 2, connect one end of the heat exchange copper tube 8 to the air cover 9 through a pipeline, and connect the other end to the air outlet slot 10 through a pipeline;

[0034] 5. Install the fan at the notch of the air outlet slot 10.

[0035] Working principle: the staff starts the equipment through the electrical control cabinet, and the cloth winding machine, electric heating fins 6 and fan are in operation; the electric heating fins 6 heat up the drying hood 5, the drying hood 5 heats the textile cloth, the moisture in the cloth evaporates, and there is a large amount of hot and humid air in the shell. The fan generates negative pressure, and the hot and humid air passes through the wind hood 9, the heat exchange copper tube 8, and the air outlet slot 10 in turn and is finally discharged out of the equipment. The heat exchange copper tube 8 quickly absorbs the heat in the hot and humid air, and the heat is then transferred back to the shell by the heat exchange hood 7. The air outlet slot 10 absorbs the waste heat in the air (specifically the hot and humid air after passing through the heat exchange copper tube 8) and returns to the shell through the waste heat fins. The waste heat is used to heat the cloth that has just entered the shell.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
