[0002] In existing technology, chopped glass fiber mats need to be dried after production. Currently, this is done in an oven. This method requires exchanging air between the oven and the outside air to ensure relatively dry air and maximize drying efficiency. However, this results in heat being released into the air, increasing energy consumption. Therefore, there is an urgent need for a drying device that can maintain relatively dry air without exhausting hot air, thus effectively avoiding energy waste. Utility Model Content

[0012] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0013] Example 1:

[0014] like Figure 1-Figure 3 As shown, the utility model discloses a drying device for producing glass fiber chopped strand mat, comprising a frame 1 and a drying box 2 arranged on the frame 1, a feed port 12 is provided on a side wall at one end of the drying box 2, a discharge port 13 is provided on a side wall at the other end of the drying box 2, a feed guide roller 10 is provided on the side wall of the drying box 2 outside the feed port 12, a unwinding roller 5 is provided on the frame 1 below the feed guide roller 10, a discharge guide roller 11 is provided on the side wall of the drying box 2 outside the discharge port 13, and a winding roller 6 is provided on the frame 1 below the discharge guide roller 11; A heating plate 14 is provided inside the drying box 2, and a dewatering tank 3 is provided below the drying box 2. The water storage tank is fitted with the lower surface of the drying box 2, and a through hole 16 is provided between the two for communication. A coil 4 is provided in the dewatering tank 3, and both ends of the coil 4 extend to the outside of the dewatering tank 3. One end of the coil 4 is connected to the cold water source, and the other end of the coil 4 is connected to the hot water terminal. A drain pipe 17 is provided at the bottom of the dewatering tank 3; a fan 7 is provided on the frame 1, and the air inlet pipe 8 of the fan 7 is connected to the dewatering tank 3, and the air outlet pipe 9 of the fan 7 is connected to the drying box 2.

[0015] A power mechanism is provided on the frame 1 at the end of the winding roller 6 , and the power mechanism drives the winding roller 6 to rotate, thereby driving the glass fiber chopped strand mat to move.

[0016] In actual operation, the heating plate 14 is activated to heat the interior of the drying chamber 2. The chopped glass strand mat on the unwinding roller 5 is output through the feed guide roller 10 and enters the drying chamber 2 from the feed port 12. It is then output from the discharge port 13, passes through the discharge guide roller 11, and is wound onto the take-up roller 6. The chopped glass strand mat is dried as it passes through the drying chamber 2. During the drying process, moisture evaporates and enters the air within the drying chamber 2, increasing the humidity within the drying chamber 2 and affecting the continuous drying of the chopped glass strands. Therefore, a dewatering tank 3 is provided below the drying chamber 2, and a coil 4 is installed within the dewatering tank 3. During operation, air from the dewatering tank 3 is transported to the drying chamber 2 by the fan 7. This causes the air in the drying chamber 2 to enter the dewatering tank 3 through the through-holes 16. The relatively high-humidity air entering the dewatering tank 3 condenses into water droplets upon encountering the cooling water coils 4, which are then dripped from the coils 4 and eventually drained out of the drain pipe 17 at the bottom of the dewatering tank 3. This circulation process reduces the humidity of the air in the drying chamber 2, thereby improving the drying efficiency and performance of the chopped glass fiber mat. Simultaneously, as the cooling water passes through the coils 4 in the dewatering tank 3, its temperature rises due to contact with the air inside the drying chamber 2 through the nozzles. This cooling water cools the water, maintaining a relatively low temperature and allowing moisture in the air to condense and precipitate. The temperature of the cooling water, which has risen significantly after passing through the coils 4, can be transported to a hot water terminal, depending on actual needs. The hot water terminal is the user end for hot water consumption, such as domestic water or industrial water.

[0017] This form can not only condense the moisture in the air in the drying box 2, but also transfer the heat to the cooling water for continued use, without causing energy waste, reducing energy consumption and ensuring stable drying efficiency and performance.

[0018] Several support rollers 15 are provided inside the drying box 2 to support the chopped glass strand mat. The number and position of the support rollers 15 can be selected as needed to adjust the path and duration of the chopped glass strand mat within the drying box 2, thereby achieving optimal drying results.

[0019] The inner bottom wall of the dewatering tank 3 is V-shaped and concave, and the drain pipe 17 is located at the lowest point of the bottom wall of the dewatering tank 3. The V-shaped concave bottom of the dewatering tank 3 can quickly collect condensed water and drain it through the drain pipe 17, preventing the condensed water from lingering at the bottom of the dewatering tank 3 and re-evaporating. The drain pipe 17 can be equipped with a valve or left open.

[0020] The position of the connection between the air inlet pipe 8 of the fan 7 and the water removal box 3 is lower than the position of the coil 4.

[0021] The connection position between the air inlet pipe 8 of the fan 7 and the water removal box 3 is lower than the coil 4, so that the air entering the air inlet pipe 8 will pass through the coil 4, so the condensation of moisture in the air is more complete and the condensation and water removal effect is better.
