Description

Technical Field

[0001] This invention relates to the field of textile printing and dyeing drying, and in particular to an energy-saving textile dryer and its working process. Background Technology

[0002] Dyeing and printing, also known as finishing and finishing, is a processing method for fabrics, yarns, ribbons, etc. It is a general term for dyeing, printing, finishing, washing, etc. With the development of scientific knowledge, dyeing and printing technology has been continuously improved, and large-scale mechanized production has been formed. Some environmentally friendly and low-carbon dyeing and printing products have gradually emerged. After dyeing in the dyeing vat, fabrics, yarns, ribbons, etc. need to be dried to ensure the effect and quality of dyeing and printing.

[0003] Currently, Chinese patent CN209351075U discloses a novel external steam heat exchanger drying system, including a steam heat exchanger, a sealed dryer, and a blower. The hot air outlet of the steam heat exchanger is connected to the air inlet of the sealed dryer through an air supply pipe. The cold air inlet of the steam heat exchanger is connected to external air, and the steam inlet of the steam heat exchanger is connected to external high-temperature steam. The steam heat exchanger is connected to the blower. The exhaust gas in the sealed dryer is discharged through the exhaust gas outlet. Cold air enters the steam heat exchanger through the cold air inlet, and high-temperature steam enters the steam heat exchanger through the steam inlet. After heat exchange between the cold air and the high-temperature steam in the steam heat exchanger, the cold air is heated and becomes hot air. Driven by the blower, the hot air enters the sealed dryer through the air supply pipe and the air inlet of the sealed dryer. The paper to be dried is transported into the sealed dryer, where the hot air dries the paper. The dried paper is then transported out of the sealed dryer, and the exhaust gas in the sealed dryer is discharged through the exhaust gas outlet.

[0004] However, after operation, the waste gas with temperature inside the sealed dryer is not fully utilized, resulting in a waste of heat energy. Moreover, during steam heat exchange, the heat generated by the steam in the air is not fully utilized. Furthermore, the steam after the steam heat exchange still carries a temperature. For example, after the 160°C steam undergoes heat exchange, the waste steam contains a high temperature of over 90°C, and only about 70°C of heat is utilized, leaving the remaining heat unused. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving dryer for textiles, which has the advantages of saving energy, reusing waste steam, reusing waste heat, and saving costs.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0017] Preferably, the second energy-saving device includes several rows of longitudinally arranged waste gas pipes, a gas-water separator, a second louver, a second high-temperature resistant filter cotton, and an exhaust pipe.

[0018] The outlet end of the exhaust duct is connected to the air inlet hopper, and the inlet end of the exhaust duct is located in the space formed by the third partition and the fourth partition.

[0019] Each of the exhaust steam pipes is S-shaped, with the outlet end of the upper exhaust steam pipe connected to the inlet end of the lower exhaust steam pipe. The inlet end of the uppermost exhaust steam pipe is located at the exhaust end of the steam pipe, and the outlet end of the lowermost exhaust steam pipe is connected to the outside. A steam-water separation device is provided at the connection between the inlet end of the uppermost exhaust steam pipe and the steam pipe.

[0020] The outer wall of the casing is provided with a second square perforation corresponding to the positions of several exhaust gas pipes. The second louver is fixedly located at the second square perforation, and a second high-temperature resistant filter cotton is fixedly embedded in the second louver.

A third louver is fixedly provided at each of the third-party shaped perforations, and a fourth high-temperature resistant filter cotton is embedded in each of the third louvers. The two upper rails are respectively fixed above the outer walls of the two third-party shaped perforations on the front and rear sides.

The two baffles are respectively slidably connected between the two upper rails and the lower rails. Cylinders are fixedly provided on the right side of the front and rear sides of the housing. The telescopic rod of each cylinder is fixedly connected to its corresponding baffle.

[0024] The working process of an energy-saving textile dryer includes the following steps:

[0025] Step 1: Push the yarn cart into the drying chamber;

[0026] Step 2: The exhaust mechanism starts working, drawing in outside air through two three-dimensional perforations, while simultaneously filtering the air through a fourth high-temperature resistant filter cotton.

[0027] Step 3: Steam is introduced into the steam pipe, and the hot steam exchanges heat with the air drawn in by the exhaust mechanism;

[0028] Step 4: At this time, the exhaust mechanism draws hot air from the space formed by the third and fourth partitions through the exhaust duct. The internal pressure of the space formed by the third and fourth partitions is different from the external pressure, which allows external air to enter the space formed by the third and fourth partitions. The external air enters through the second high-temperature resistant filter cotton on the second louver and passes through several rows of longitudinally arranged waste steam pipes. The waste steam with residual heat in several waste steam pipes will heat the incoming cold air, so as to achieve the utilization of waste steam.

[0029] Step 5: The hot air after heat exchange enters the square shell through the air outlet pipe, and after being filtered by the third high-temperature resistant filter cotton of the square shell, it is discharged into the drying chamber. At this time, the left opening of the square shell is located between the first air guide plate and the second air guide plate of the yarn cart. The hot air is discharged through the square shell into the space between the first air guide plate and the second air guide plate, and rises through several circular perforations of the first air guide plate to dry the textiles on several rollers.

[0030] Step Six: The heated air rises and passes over the textiles to be dried. At this point, the air is still warm and moist. The exhaust system continues to draw out the warm, moist air. Most of the hot air is drawn into the fan, while the moisture is filtered by the first high-temperature resistant filter cotton. Along with some of the hot air, the moisture is discharged through the exhaust pipe. At the same time, the exhaust system draws out outside air through two third louvers and a fourth high-temperature resistant filter cotton.

[0031] Step 7: In order to further extract the warm and humid air in the drying chamber, at this time, two cylinders work and two baffles block half of the third louver. At this time, the pressure in the air inlet chamber is inconsistent with that in the outside, thereby increasing the amount of warm and humid air extracted from the drying chamber by the fan.

[0032] In summary, the present invention has the following beneficial effects:

[0033] 1. By setting the first louver and the first high-temperature resistant filter cotton of the first energy-saving device, the waste heat of the drying chamber can be extracted and discharged into the heat exchange mechanism by the fan for heat exchange, thereby saving energy and achieving the effect of faster heating.

[0034] 2. By setting up two baffles, two upper rails, two lower rails and two cylinders in the first energy-saving device, the air inlet of the air inlet chamber can be reduced, so that the pressure inside the air inlet chamber is inconsistent with that outside, thereby increasing the effect of the fan in drawing air from inside the drying chamber.

[0035] 3. By installing the second energy-saving device, the steam after heat exchange can be heat exchanged again, thus achieving the effect of reusing waste steam. Attached Figure Description

[0041] The present invention will be further described in detail below with reference to the accompanying drawings.

[0042] Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings.

[0043] Example 1:

[0044] An energy-saving dryer for textiles, such as Figure 1-2 As shown, it includes a housing 1, an exhaust mechanism 2, and a heat exchange mechanism 3;

[0045] The casing 1 is a square frame, and the outer part is covered with iron sheet to form a seal. The number of exhaust mechanisms 2 and heat exchange mechanisms 3 is determined according to the size of the casing 1. In this invention, two exhaust mechanisms 2 and two heat exchange mechanisms 3 are used.

[0046] The lower left side of the inside of the casing 1 is the drying chamber 4, which contains a yarn cart 5 and textiles. The yarn cart 5 is used to dry the textiles on it. A double door is provided on the left side of the drying chamber 4 to facilitate the pushing and pulling of the yarn cart 5.

[0047] The upper left side of the inside of the casing 1 is the air inlet chamber 6, which is used to facilitate the exhaust mechanism 2 to draw in external air. The air inlet chamber 6 is equipped with a first energy-saving device 7, which is used to facilitate the exhaust mechanism 2 to draw in the hot air inside the drying chamber 4.

[0048] The upper right side of the inside of the casing 1 is provided with an exhaust mechanism 2, which is used to transport the extracted outside air and hot air to the heat exchange mechanism 3.

[0049] A heat exchange mechanism 3 is provided on the right side of the lower end of the casing 1. It is used to heat the external air drawn by the exhaust mechanism 2 and the hot air of the drying chamber 4 and transport them into the drying chamber 4. A second energy-saving device 8 is provided at the heat exchange mechanism 3. It is used to re-exchange the waste steam to be discharged after heat exchange to generate hot air, which is then drawn into the heat exchange mechanism 3 by the exhaust mechanism 2.

[0050] A first partition plate 9 is provided between the air inlet chamber 6 and the drying chamber 4, a second partition plate 11 is provided between the air inlet chamber 6 and the exhaust mechanism 2, a third partition plate 12 is provided between the exhaust mechanism 2 and the heat exchange mechanism 3, and a fourth partition plate 13 is provided between the drying chamber 4 and the heat exchange mechanism 3. These partition plates are used to separate the air inlet chamber 6, the drying chamber 4, the exhaust mechanism 2, and the heat exchange mechanism 3. At the same time, since the exhaust mechanism 2 generates heat when it is working, it is not sealed to prevent it from burning out. Therefore, the second partition plate 11 and the third partition plate 12 are used to ensure that the heat in the drying chamber 4 and the heat exchange mechanism 3 is not wasted.

[0051] A vertical exhaust pipe 10 is fixedly installed in the middle of the air intake chamber 6. The bottom of the exhaust pipe 10 is located inside the drying chamber 4, and the top of the exhaust pipe 10 is located at the top of the casing 1. The exhaust pipe 10 connects the drying chamber 4 with the outside of the casing 1, and the exhaust pipe 10 is used to discharge the warm and humid air inside the drying chamber 4 to the outside.

[0052] To further utilize the warm, humid air inside the drying chamber 4, a first energy-saving device 7 is installed on the exhaust pipe. The first energy-saving device 7 includes a first louver 711 and a first high-temperature resistant filter cotton 712. The exhaust pipe 10 has a square cross-section, and each side wall of the exhaust pipe 10 has a first square perforation. Each first square perforation is fitted with a first louver 711, and each first louver 711 is fitted with a first high-temperature resistant filter cotton 712. When extracting warm, humid air, most of the hot air is drawn into the fan 211, while the humid air is filtered by the first high-temperature resistant filter cotton 712 as it passes through the first high-temperature resistant filter cotton 712, and is discharged through the exhaust pipe 10 along with some of the hot air.

[0053] The exhaust mechanism 2 includes a fan 211, a motor 212, an air inlet 213, and a filter screen 214. The air inlet on the left side of the air inlet 213 is located inside the air inlet chamber 6. The air outlet on the right side of the air inlet 213 is connected to the air inlet of the fan 211. The motor 212 is connected to the fan 211 for transmission. The filter screen 214 is fixedly located at the air inlet of the air inlet 213. The air outlet of the fan 211 is connected to the air inlet of the heat exchange mechanism 3.

[0054] The heat exchange mechanism 3 includes a connecting pipe 311, a heat exchange pipe 312, an air outlet pipe 313, and a steam pipe 314. The inlet end of the connecting pipe 311 is connected to the air outlet of the fan 211. The air inlet of the heat exchange pipe 312 is connected to the air outlet of the connecting pipe 311. The air outlet of the heat exchange pipe 312 is connected to the air inlet of the air outlet pipe 313. The air outlet of the air outlet pipe 313 is connected to the drying chamber 4. The steam pipe 314 is located inside the heat exchange pipe 312. Several first circular perforations are opened on the side wall of the heat exchange pipe 312. The steam pipe 314 is spiral in shape. The steam inlet and exhaust outlet of the steam pipe 314 are both connected to the outside.

[0055] Hot steam is supplied to the steam pipe 314 from the outside, and it exchanges heat with the air drawn by the exhaust mechanism 2 at the heat exchange pipe 312. Then, through several first circular perforations, the air near the heat exchange pipe 312 can be exchanged for heat. At this time, the hot air after heat exchange is discharged into the drying chamber 4 through the exhaust pipe 313.

[0056] In order to further utilize the waste heat generated by the heat exchange in the space formed by the third partition plate 12 and the fourth partition plate 13 and the waste steam after the heat exchange, the steam pipe 314 is provided with a second energy-saving device 8 between the outlet and the heat exchange pipe 312. The second energy-saving device 8 includes several rows of longitudinally arranged waste steam pipes 811, steam-water separation device 812, second louvers 813, second high-temperature resistant filter cotton 814, and exhaust pipe 815.

[0057] The outlet end of the exhaust duct 815 is connected to the air inlet duct 213, and the inlet end of the exhaust duct 815 is located in the space formed by the third partition plate 12 and the fourth partition plate 13. The fan 211 draws out the hot air through the exhaust duct 815 and then discharges it back into the heat exchange duct 312 for heat exchange, which can effectively ensure that the heat of the hot steam is not wasted.

[0058] Each waste steam pipe 811 is S-shaped, with the outlet of the upper waste steam pipe 811 connected to the inlet of the lower waste steam pipe 811. The inlet of the uppermost waste steam pipe 811 is located at the exhaust end of the steam pipe 314, and the outlet of the lowermost waste steam pipe 811 is connected to the outside. A steam-water separator 812 is installed at the connection between the inlet of the uppermost waste steam pipe 811 and the steam pipe 314. A second square perforation is opened on the outer wall of the casing 1 at a position corresponding to the positions of several waste steam pipes 811. A second louver 813 is fixedly located at the second square perforation, and a second high-temperature resistant filter cotton 814 is fixedly embedded in the second louver 813. In order to utilize the waste heat of the waste steam, after passing through the fan 2 When the heated air in the space formed by the third partition plate 12 and the fourth partition plate 13 is extracted, the internal pressure of the space formed by the third partition plate 12 and the fourth partition plate 13 is inconsistent with the external pressure. A second square perforation is provided, and a second louver 813 is provided at the second square perforation. A second high-temperature resistant filter cotton 814 is fixedly embedded in the second louver 813, which allows external air to enter into the space formed by the third partition plate 12 and the fourth partition plate 13. When the external air enters, it will pass through several rows of longitudinally arranged waste steam pipes 811. The waste steam with residual heat in the waste steam pipes 811 will heat the incoming cold air, thus achieving the utilization of waste steam.

[0059] A square opening is provided at the lower end of the fourth partition plate 13. A square shell 14 is provided on the right side of the fourth partition plate 13 corresponding to the square opening. An opening is provided on the left side of the square shell 14. A third high-temperature resistant filter cotton 15 is provided at the left opening of the square shell 14.

A second air guide plate 513 is provided inside the support 511 above the first air guide plate 512. Several round rollers 514 are arranged in an array at the upper end of the inside of the support 511. Several round perforations are opened in the second air guide plate 513. The left side opening of the square shell 14 is located between the first air guide plate 512 and the second air guide plate 513. The heated gas is discharged through the square shell 14 into the space between the first air guide plate 512 and the second air guide plate 513, and rises through the several round perforations of the first air guide plate 512 to dry the textiles on the several round rollers 514.

[0061] Example 2:

[0062] An energy-saving dryer for textiles, such as Figure 3As shown, in order to further utilize the warm and humid air in the drying chamber 4, a first energy-saving device 7 can be provided on the first partition plate 9. The first energy-saving device 7 includes a first louver 711 and a first high-temperature resistant filter cotton 712. The first partition plate 9 has a first square perforation, the first louver 711 is embedded in the first square perforation, and the first high-temperature resistant filter cotton 712 is embedded on the first louver 711.

[0063] When extracting warm, humid air, most of the hot air is drawn into the fan 211, while the humid air is filtered by the first high-temperature resistant filter cotton 712 and discharged through the exhaust pipe 10 along with some of the hot air.

[0064] Example 3:

[0065] An energy-saving dryer for textiles, such as Figure 1 , Figure 2 , Figure 4 As shown, the first energy-saving device 7 also includes two baffles 816, two upper rails 817, two lower rails 818, and two cylinders 819. The housing 1 is provided with third-party shaped perforations on the left side, front side, and rear side of the air intake chamber 6. A third louver 820 is fixedly provided at each of the third-party shaped perforations. A fourth high-temperature resistant filter cotton 821 is embedded in each of the third louvers 820. The two upper rails 817 are respectively fixed above the outer walls of the two third-party shaped perforations on the front and rear sides. The two lower rails 818 are respectively fixed below the outer walls of the two third-party shaped perforations on the front and rear sides. The two baffles 816 are slidably connected between the two upper rails 817 and the lower rails 818. Cylinders 819 are fixedly provided on the right side of the front and rear sides of the housing 1. The telescopic rod of each cylinder 819 is fixedly connected to its corresponding baffle 816.

[0066] During the extraction of warm, humid air, the extension rods of the two cylinders 819 extend, reducing the two third-dimensional perforations in the air intake chamber 6, causing the pressure inside the air intake chamber 6 to be inconsistent with the external pressure, thereby increasing the effect of the fan 211 in extracting air from the inside of the drying chamber 4.

[0067] Specific implementation process:

[0068] Step 1: Push the yarn spool 5 into the drying chamber 4 and close the double doors of the drying chamber 4.

[0069] Step 2: The exhaust mechanism 2 starts working, drawing in outside air through two three-dimensional perforations, while simultaneously filtering the air through the fourth high-temperature resistant filter cotton 821;

[0070] Step 3: Steam is introduced into the steam pipe 314, and the hot steam exchanges heat with the air drawn by the exhaust mechanism 2.

[0071] Step 4: At this time, the exhaust mechanism 2 extracts the hot air in the space formed by the third partition plate 12 and the fourth partition plate 13 through the exhaust pipe 815. The internal pressure of the space formed by the third partition plate 12 and the fourth partition plate 13 is different from the external pressure, which allows the external air to enter the space formed by the third partition plate 12 and the fourth partition plate 13. The external air enters through the second high-temperature resistant filter cotton 814 on the second louver 813 and will pass through several rows of longitudinally arranged waste steam pipes 811. The waste steam with residual heat in the waste steam pipes 811 will heat the incoming cold air, so as to achieve the utilization of waste steam.

[0072] Step 5: The hot air after heat exchange enters the square shell 14 through the air outlet duct 313. After being filtered by the third high-temperature resistant filter cotton 15 of the square shell 14, it is discharged into the drying chamber 4. At this time, the left opening of the square shell 14 is located between the first air guide plate 512 and the second air guide plate 513 of the yarn cart 5. The hot air is discharged through the square shell 14 into the space between the first air guide plate 512 and the second air guide plate 513, and rises through several circular perforations of the first air guide plate 512 to dry the textiles on several round rollers 514.

[0073] Step Six: The heated air rises and passes over the textiles to be dried. At this time, the air is hot and moist. The exhaust mechanism 2 continues to draw out the warm and moist air. Most of the hot air is drawn into the fan 211, while the moisture is filtered by the first high-temperature resistant filter cotton 712. Along with some of the hot air, it is discharged through the exhaust pipe 10. At the same time, the exhaust mechanism 2 draws out the outside air through the two third louvers 820 and the fourth high-temperature resistant filter cotton 821.

[0074] Step 7: In order to further extract the warm and humid air in the drying chamber 4, at this time, the two cylinders 819 are working, and the two baffles 816 block half of the third louver 820. At this time, the pressure inside the air inlet chamber 6 is inconsistent with the outside pressure, thereby increasing the fan 211 to extract more warm and humid air from the inside of the drying chamber 4.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

9. A workflow of an energy-saving textile dryer, characterized in that, The following steps are included: Step 1: Push the yarn spool (5) into the drying chamber (4); Step 2: The exhaust mechanism (2) starts working, and the two third-dimensional perforations draw in outside air, while filtering the air through the fourth high-temperature resistant filter cotton (821); Step 3: Steam is introduced into the steam pipe (314), and the hot steam exchanges heat with the air drawn by the exhaust mechanism (2); Step 4: At this time, the exhaust mechanism (2) extracts the hot air in the space formed by the third partition plate (12) and the fourth partition plate (13) through the exhaust pipe (815). The internal pressure of the space formed by the third partition plate (12) and the fourth partition plate (13) is inconsistent with the external pressure, which allows the external air to enter the space formed by the third partition plate (12) and the fourth partition plate (14). The external air enters through the second high-temperature resistant filter cotton (814) on the second louver (813), and will pass through several rows of longitudinally arranged waste steam pipes (811). The waste steam with residual heat in the several waste steam pipes (811) will heat the cold air that enters, so as to achieve the utilization of waste steam. Step 5: The hot air after heat exchange enters the square shell (14) through the air outlet pipe (313), and is discharged into the drying chamber (4) after being filtered by the third high temperature resistant filter cotton (15) of the square shell (14). At this time, the left opening of the square shell (14) is located between the first air guide plate (512) and the second air guide plate (513) of the yarn cart (5). The hot gas is discharged through the square shell (14) into the space between the first air guide plate (512) and the second air guide plate (513), and rises through several circular perforations of the first air guide plate (512) to dry the textiles on several round rollers (514). Step 6: The hot air rises and passes over the textiles to be dried. At this time, the air is hot and moist. The exhaust mechanism (2) is still drawing out the warm and moist air. Most of the hot air is drawn into the fan (211). When the moisture passes through the first high-temperature resistant filter (712), it is filtered by the first high-temperature resistant filter (712). Along with some of the hot air, it is discharged through the exhaust pipe (10). At the same time, the exhaust mechanism (2) draws out the outside air through the two third louvers (820) and the fourth high-temperature resistant filter (821). Step 7: In order to further extract the warm moisture in the drying chamber (4), at this time, the two cylinders (819) work and the two baffles (816) block half of the third louver (820). At this time, the pressure inside the air inlet chamber (6) is inconsistent with the outside pressure, thereby increasing the fan (211) to extract more warm moisture inside the drying chamber (4).
