Description

Technical Field

[0001] The present invention belongs to the technical field of dehydration and drying, and particularly relates to a dehydration and drying device for textiles. Background Art

[0002] During the manufacturing process of textiles, a dyeing process is required. Generally, the dyeing process adopts an immersion method. After immersion, it needs to be washed to remove excess dyes. The washed textiles contain a large amount of water and need to be dehydrated and dried for subsequent corresponding integration and winding.

[0003] A drying and dehydrating device for textile fabrics disclosed in a Chinese patent with the application number CN202320722100.X includes a drying box, a dehydration mechanism, a water collection cylinder, and a conveying roller; both ends of the drying box are provided with inlets and outlets for the textile fabric to enter and exit, the top surface of the drying box is provided with a ventilation opening, and a number of blowers are evenly arranged at equal intervals in the ventilation opening. An electric heating grid parallel to the ventilation opening is installed in the drying box, and the electric heating grid is arranged below the blowers; the dehydration mechanism includes a squeezing dehydration roller arranged side by side with the conveying roller at one end of the drying box. Through the cooperation of the provided blowers and the electric heating grid, the textile fabric passing through the drying box can be dried, and the squeezing dehydration roller arranged at the feeding end can squeeze out the water in the textile fabric, improving the drying efficiency. However, the squeezing dehydration roller of the above device is arranged in the drying box, and the water squeezed out remains in the drying box and will contact the hot air, generating water vapor that will affect the drying effect; in addition, the drying hot air only contacts one side of the textile fabric, the contact between the drying hot air and the textile fabric is insufficient, the drying effect is not good, and the hot air cannot be recycled, which does not meet the actual production requirements. Summary of the Invention

[0004] The purpose of the present invention is to provide a dehydration and drying device for textiles in view of the deficiencies of the prior art.

[0005] To achieve the above purpose, the specific technical solution of the present invention is as follows: A dehydration and drying device for textiles includes a frame, on which a heating box and a dehydration tank device symmetrically arranged left and right are fixedly installed. Between the upper openings and the lower openings of the heating box and the dehydration tank device, drying air duct devices symmetrically arranged up and down are respectively connected. A heating device is provided on the heating box. The dehydration tank device includes a dehydration tank, an inlet and outlet is opened on the outside of the dehydration tank, and an elastic guide roller device symmetrically arranged up and down is provided on the inlet and outlet. A fixed bracket is fixedly installed directly outside the inlet and outlet, and a pressure roller device is installed on the fixed bracket. A suction box is provided between the heating box and the dehydration tank device, and the suction box is communicated with the drying air duct device and the dehydration tank device. A condensation and dehumidification device is provided on the suction box, and an eddy current blower is provided on the condensation and dehumidification device. The eddy current blower is communicated with the heating device through a duct.

[0006] As a further setting of the above solution, the drying air duct device includes an annular air duct. The annular air duct, the heating box, and the dehydration box form a closed air duct. A support roller distributed circumferentially is rotatably connected in the annular air duct. The support roller is parallel to the central axis of the annular air duct. Second air pipes distributed circumferentially are arranged on the inner wall of the annular air duct. The second air pipes are communicated with the air extraction box.

[0007] As a further setting of the above solution, a first air pipe is arranged inside the dehydration box. The first air pipe is communicated with the air extraction box. Chute grooves are opened on the upper and lower end faces of the feeding and discharging opening. A through groove is opened at the center of the fixed bracket. Guide holes are opened on both sides of the through groove. A water tank is fixedly connected to the lower end outside the dehydration box. A drainage device is arranged on the water tank. The water tank is located directly below the fixed bracket.

[0008] As a further setting of the above solution, the elastic guide roller device includes a sliding table. The sliding table is slidably connected in the chute groove. An installation bracket is fixedly connected to the lower end of the sliding table. A guide roller is rotatably connected to the installation bracket. The guide roller is parallel to the central axis of the annular air duct. A spring column is arranged at the upper end of the sliding table. The outer end of the spring column is fixedly installed in the chute groove.

[0009] As a further setting of the above solution, the pressing roller device includes a rotating bracket and a cylinder device. A pressing roller is rotatably connected to the rotating bracket. The pressing roller is parallel to the central axis of the annular air duct. A guide rod is arranged on the left end face of the rotating bracket. The guide rod is slidably connected with the guide hole. The output end of the cylinder device is connected with a connecting rod. The connecting rod is slidably connected with the through groove. The outer end of the connecting rod is fixedly connected with the left end face of the rotating bracket. The cloth first enters the dehydration box under the elastic support of the lower guide roller, passes through the lower drying air duct device, the heating box, and the upper drying air duct device counterclockwise in sequence, then winds back into the dehydration box, and finally winds out of the dehydration box under the extrusion of the upper guide roller. The cloth is in rolling contact with the support roller and is located outside the support roller.

[0010] As a further setting of the above solution, a fixed frame is fixedly connected to the right side of the rotating bracket. A scraper is fixedly connected in the fixed frame. The scraper abuts against the pressing roller. The scraper does not affect the free rotation of the pressing roller.

[0011] As a further setting of the above solution, the air inlet of the eddy current fan is communicated with the air outlet of the condensation dehumidification device. The air outlet of the eddy current fan is communicated with the heating device through a duct. The eddy current fan provides power for the air circulation. The condensation dehumidification device dehumidifies the circulating air.

[0012] The beneficial effects of the present invention: When the fabric enters the dehydration tank, the two elastic guide roller devices elastically support the feeding end and the discharging end of the fabric. There is a gap between the guide rollers. The cylinder device drives the pressure roller to approach the guide rollers through the connecting rod. The pressure roller simultaneously rolls and squeezes the fabric wound around the two guide rollers, squeezing and dehydrating the fabric outside the dehydration tank. When performing squeezing and dehydration, the scraper performs a wet-dry isolation operation on the pressure roller to prevent the water on the pressure roller from contaminating the dried fabric. The discharged water directly flows into the water tank for collection, avoiding the water vapor generated by the discharged water from affecting the fabric drying. The pressure roller also effectively seals the dehydration tank to prevent external air from entering the drying air duct device or hot air from leaking out, causing additional heat loss. Under the action of the eddy current fan, the hot air in the equipment circulates between the heating box, the annular air duct, and the air extraction box. The condensation and dehumidification device simultaneously performs drying and dehumidification to improve the heat utilization efficiency and further improve the drying efficiency.

[0013] The heating device heats the air and blows the hot air into the heating box and the annular air duct. At this time, the hot air is located outside the fabric. The eddy current fan forms a negative pressure in the air extraction box, and extracts the air from the inside of the fabric through the first air pipe and the second air pipe, creating a pressure difference between the inside and outside of the fabric. The hot air passes through the fabric from the outside or circulates from both sides of the fabric to the inside, and the hot air fully contacts the fabric, greatly improving the drying effect.

[0019] As Figure 2 、 Figure 3 shown, the drying air duct device 4 includes an annular air duct 401. The annular air duct 401 and the heating box 2 and the dehydration tank 301 form a closed air duct. Support rollers 402 which are circumferentially distributed are rotatably connected in the annular air duct 401. The support rollers 402 are parallel to the central axis of the annular air duct 401. Second air pipes 403 which are circumferentially distributed are provided on the inner wall of the annular air duct 401. The second air pipes 403 are communicated with the suction box 6.

[0020] As Figure 4 、 Figure 5 shown, a first air pipe 302 is provided inside the dehydration tank 301. The first air pipe 302 is communicated with the suction box 6. Chutes 3012 are opened on the upper and lower end faces of the feeding and discharging port 3011. A through groove 3014 is opened at the center of the fixed bracket 3013. Guide holes 3015 are opened on both sides of the through groove 3014. A water tank 304 is fixedly connected to the lower end of the outer side of the dehydration tank 301. A drainage device 3041 is provided on the water tank 304. The water tank 304 is located directly below the fixed bracket 3013.

[0021] As Figure 6As shown, the elastic guide roller device 303 includes a sliding table 3031 which is slidably connected in the chute 3012. A mounting bracket 3032 is fixedly connected to the lower end of the sliding table 3031. A guide roller 3033 is rotatably connected to the mounting bracket 3032. The guide roller 3033 is parallel to the central axis of the annular air duct 401. A spring column 3034 is provided at the upper end of the sliding table 3031. The outer end of the spring column 3034 is fixedly installed in the chute 3012. The elastic guide roller device 303 elastically supports the fabric.

[0022] As Figure 7 As shown, the pressing roller device 5 includes a rotating bracket 501 and a cylinder device 502. A pressing roller 504 is rotatably connected to the rotating bracket 501. The pressing roller 504 is parallel to the central axis of the annular air duct 401. A guide rod 503 is provided on the left end face of the rotating bracket 501. The guide rod 503 is slidably connected to the guide hole 3015. The output end of the cylinder device 502 is connected with a connecting rod 5021. The connecting rod 5021 is slidably connected to the through groove 3014. The outer end of the connecting rod 5021 is fixedly connected to the left end face of the rotating bracket 501. A fixed frame 505 is fixedly connected to the right side of the rotating bracket 501. A scraper 506 is fixedly connected in the fixed frame 505. The scraper 506 abuts against the pressing roller 504. The scraper 506 does not affect the free rotation of the pressing roller 504. The fabric 10 first enters the dehydration tank 301 under the elastic support of the lower guide roller 3033. The fabric 10 passes through the lower drying air duct device 4, the heating box 2, and the upper drying air duct device 4 counterclockwise in sequence, and then rewinds back into the dehydration tank 301. Finally, the fabric 10 is wound out of the dehydration tank 301 under the extrusion of the upper guide roller 3033. The fabric 10 is in rolling contact with the support roller 402 and is located outside the support roller 402.

[0023] Working process: The feeding end 1001 of the fabric 10 first enters the dehydration tank 301 under the elastic support of the lower guide roller 3033. Under the rolling support of the support roller 402 in the annular air duct 401, the fabric 10 sequentially passes through the lower annular air duct 401, the heating box 2, and the upper annular air duct 401 counterclockwise, and then rewinds back into the dehydration tank 301. The discharging end 1002 of the fabric 10 finally exits the dehydration tank 301 under the extrusion of the upper guide roller 3033. The fabric 10 is in rolling contact with the support roller 402 and is located outside the support roller 402. The two elastic guide roller devices 303 elastically support the feeding end 1001 and the discharging end 1002 of the fabric 10, and there is a gap between the guide rollers 3033. During the drying process of the fabric 10, the cylinder device 502 drives the pressing roller 504 to approach the guide roller 3033 through the connecting rod 5021. The pressing roller 504 simultaneously performs rolling extrusion on the fabric 10 wound around the two guide rollers 3033. The pressing roller 504 cooperates with the lower guide roller 3033 to extrude and dehydrate the fabric 10 outside the dehydration tank 301. When performing extrusion dehydration, the scraper 606 performs a wet-dry isolation operation on the pressing roller 504 to prevent the water on the pressing roller 504 from contaminating the dried fabric 10 during rotation. The discharged water directly flows into the water tank 304 for collection, avoiding the water vapor generated by the discharged water contacting the hot air in the dehydration tank and affecting the drying of the fabric 10. The pressing roller 504 cooperates with the two guide rollers 3033 to effectively seal the inlet and outlet 3011 of the dehydration tank 301, preventing external air from entering the drying air duct device 4 or the hot air from leaking out, resulting in additional heat loss. Under the action of the eddy current fan 8, the hot air in the equipment circulates between the heating box 2, the annular air duct 401, and the air extraction box 6, and the condensation and dehumidification device 7 simultaneously performs drying and dehumidification.

[0024] When drying the fabric, the heating device 201 heats the air and blows the hot air into the heating box 2 and the annular air duct 401. At this time, the hot air is distributed outside the fabric 10. The eddy current fan 8 forms a negative pressure in the air extraction box 6, and extracts the air from the inside of the fabric 10 through the first air pipe 302 and the second air pipe 403, creating a pressure difference between the inside and outside of the fabric 10. The pressure outside the fabric 10 is higher than the pressure inside the fabric 10, and the hot air passes through the fabric 10 from the outside or flows into the inside from both sides of the fabric 10, ensuring that the hot air is in full contact with the fabric 10 and greatly improving the drying effect.
