Description

Technical Field

[0001] This invention relates to the field of energy-saving steam ironing technology in garment factories, specifically to an energy-saving steam generator that can automatically remove limescale during ironing. Background Technology

[0002] In garment manufacturing, garment pressing is a crucial step in the garment production process. It involves using high-temperature steam to smooth out uneven areas of the garment, achieving a smoother appearance and creating a more three-dimensional and aesthetically pleasing finish. The pressing process is vital to the final appearance of a garment, and it utilizes a steam generator, also called a steam heat source (commonly known as a boiler). This is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of "boiler" refers to a water-containing container heated over a fire, while "furnace" refers to the place where fuel is burned. A boiler consists of both the boiler and the furnace. Steam boilers, sometimes called steam generators, are an important component of steam power systems. A steam generator is a device that converts water into steam through heating and is widely used in industrial, medical, and commercial fields.

[0003] In the garment factory production process, garments and other clothing need to be ironed. The main functions of ironing are: 1. Shaping the garment pieces: Ironing helps the fabric to shrink and regain its shape, eliminating wrinkles and maintaining the smoothness of the fabric; 2. Creating a three-dimensional shape for the garment: Utilizing the thermoplasticity of textile fibers, the elasticity and warp and weft density and direction of the fabric are changed, making the garment shape more in line with the human body curves and functional requirements, achieving the goals of aesthetic appearance and wearing comfort; 3. Finishing the garment: Making the garment smooth and flat, with neat seams and pleats, compensating for defects in the sewing process. Ironing operations require the use of a steam generator, which uses a heating medium during operation. Steam is generated by heating water. However, scale will accumulate on the outside of the heating medium after long-term use. The water used is usually tap water or industrial water, which is more prone to scale formation due to water quality issues. In the long run, this will reduce heating efficiency and shorten service life. Existing ironing steam generators lack the ability to remove scale due to the limited space for complex cleaning structures. Furthermore, the scale problem reduces energy conversion efficiency over time, and the lack of heat recovery and heat exchange functions reduces energy saving. Therefore, an energy-saving steam generator for ironing that can automatically remove scale is proposed. Summary of the Invention

[0014] Preferably, a control panel is fixedly installed on the outside of the insulated tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. After the operation is completed, the heating tube mechanism is closed and the drain pipe is opened to drain the water from the inside of the heat-insulating inner tank. At this time, the high-temperature resistant submersible pump pumps water into the inlet pipe. At this time, solenoid valve one and high-temperature resistant solenoid valve are closed and solenoid valve two is opened. The water flows through the inlet pipe to the connector and is guided to the opposite side of the main sealing piston plate and the partition plate. The water flow pressurizes the opposite side of the main sealing piston plate and the partition plate and pushes the permanent magnet out of the magnetic attraction range. It also pushes the main sealing piston plate to slide on the outside of the heating tube mechanism. The piston sealing ring slides on the outside of the heating tube mechanism. The outer side of the heating tube mechanism is scraped off and cleaned by the first shovel cone. With the help of electromagnetic induction, when the water flows through the magnetic field, the calcium and magnesium ions in the water will be magnetized, changing their crystal form and making them less likely to adhere to the wall of the container. The soft scale formed will be scraped off by the first shovel cone and discharged with the water flow. Thus, after the operation is completed, the water is drained and cleaned every day, thereby achieving the purpose of self-cleaning scale, indirectly improving heating efficiency, saving energy, and indirectly increasing service life.

[0016] 2. After cleaning, water is injected into the bottom of the inner cavity of the heat-insulating liner, pushing the main sealing piston plate upward. The water flows through the top slot of the partition to the inside of the fixed pipe, and finally out through the high-temperature resistant flexible pipe and the suction ring frame, thus achieving the effect of cleaning the high-temperature resistant flexible pipe and the suction ring frame. After the main sealing piston plate reaches the position, the sealing pipe and the fixed pipe are inserted and re-sealed. The permanent magnet is attracted to the magnetic position at the bottom of the partition, thereby realizing the cleaning, resetting and rinsing operation of the structure, further increasing the use effect of the structure.

[0017] 3. When steam styling is performed using a handheld steam nozzle, the Roots vacuum pump starts. The airflow first enters through the holes in the suction ring frame. As the handheld steam nozzle performs steam styling, excess steam is drawn in through the holes in the suction ring frame. The airflow then enters through the interlayer between the protective corrugated pipe and the high-temperature resistant flexible pipe. The airflow enters the interior of the storage cone through guide hole one, and then enters the space between the storage cone and the insulation inner liner through guide hole two. The airflow is then guided into the interior of the spiral coil through the connecting pipe. At this time, the recovered steam is immersed in water and condensed in the spiral coil. This achieves the recovery and condensation of redundant steam, and uses the excess heat to assist in heating the water flow on the opposite side of the insulation tank and the insulation inner liner. This increases the water temperature and reduces the energy required for heating and evaporation of the heating tube mechanism, thereby achieving energy saving and avoiding the problem of excessive steam interfering with visibility and increasing the humidity of the environment.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10This invention provides a technical solution: an energy-saving steam generator for ironing that can automatically remove scale, comprising a heat preservation tank 1, an inner heat preservation liner 15 fixedly installed inside the heat preservation tank 1, a spacer ring 16 fixedly sleeved on the outer side of the top of the inner heat preservation liner 15, a partition plate 17 fixedly sleeved on the inner side of the top of the inner heat preservation liner 15, a water inlet corrugated pipe 7 connected to one side of the top of the heat preservation tank 1, one end of the water inlet corrugated pipe 7 located inside the heat preservation tank 1 connected to a float level controller 33, and the other end of the water inlet corrugated pipe 7 connected to a connector 8, a filter plug 13 movably sleeved on the inner side of the connector 8, and the inner cavity of the heat preservation tank 1... A high-temperature resistant submersible pump 40 is fixedly installed at the bottom. The output end of the high-temperature resistant submersible pump 40 is connected to an inlet pipe 26. A solenoid valve 44 is installed inside the inlet pipe 26. A connector 37 is connected to the top of the inlet pipe 26. Two switching pipes 41 are connected to the side of the inlet pipe 26 near the end of the high-temperature resistant submersible pump 40. A solenoid valve 19 is installed inside each of the two switching pipes 41. A one-way valve 42 is installed inside each of the two switching pipes 41. A threaded groove 24 is opened inside the inner wall of the heat-insulating inner liner 15. Several guide holes 34 are connected to the inner side of the threaded groove 24. The bottom of the inner cavity of the heat-insulating inner liner 15 is fixed. A heating element mechanism 20 is fixedly installed. A main sealing piston plate 35 is movably sleeved inside the insulated inner liner 15. A number of piston sealing rings 38 are fixedly installed on the inner side of the main sealing piston plate 35 through holes. A shovel cone 39 is fixedly installed at the bottom of the piston sealing rings 38. A number of permanent magnets 36 are fixedly installed on the top of the main sealing piston plate 35. A connecting sealing tube 31 is fixedly sleeved in the middle of the main sealing piston plate 35. A one-way valve 32 is provided inside the connecting sealing tube 31. A storage cone 28 is fixedly installed on the top of the partition 17. A water supply pipe 6 is connected to the top of the storage cone 28. The top of the storage cone 28 is provided with several guide holes 30. The top of the storage cone 28 is fixedly sleeved with a protective bellows 9. The bottom end of the protective bellows 9 is provided with several guide holes 29. Several cross-shaped inner supports 27 are fixedly installed inside the protective bellows 9. A high-temperature resistant flexible tube 14 is fixedly sleeved inside the cross-shaped inner supports 27. A fixed tube 25 is fixedly installed at the bottom end of the high-temperature resistant flexible tube 14. A high-temperature resistant solenoid valve 43 is installed inside the fixed tube 25. The end of the protective bellows 9 away from the heat preservation tank 1 is connected to a handheld steam nozzle 10. An air intake ring frame 11 is fixedly sleeved inside the handheld steam nozzle 10.

[0031] The working principle of the above technical solution is as follows: During use, the user connects the external water tap to connector 8 to fill the inner side of the insulation tank 1 with water. Then, the float level controller 33 starts and stops. Next, the high-temperature submersible pump 40 starts, pumping water from the opposite side of the insulation tank 1 and the inner insulation liner 15. At this time, solenoid valve 44 closes, and solenoid valve 19 inside the switching pipe 41 at the bottom closes. Water then flows through the high-temperature submersible pump 40 to the switching pipe 41 and through the one-way valve 42 into the threaded groove 24. Water is then guided into the inner insulation liner 15 through the threaded groove 24 and the guide hole 34. After the water flows over the heating section of the heating tube mechanism 20, the heating tube mechanism 20 starts, heating the water and generating steam that passes through the docking... The sealed tube 31 leads out, passes through the one-way valve 32, and then into the fixed tube 25. The high-temperature resistant solenoid valve 43 is opened, and airflow enters the suction ring frame 11 through the high-temperature resistant flexible tube 14. Steam reaches the ironed fabric through the holes in the suction ring frame 11. After the operation is completed, the heating tube mechanism 20 is closed, and the discharge pipe 4 is opened to drain water from the heat-insulating inner liner 15. At this time, the high-temperature resistant submersible pump 40 pumps water into the inlet pipe 26. Solenoid valves 19 and 43 are closed, and solenoid valve 44 is opened. Water flows through the inlet pipe 26 to the connector 37 and is guided to the opposite side of the main sealing piston plate 35 and the partition plate 17. The water pressures the opposite side of the main sealing piston plate 35 and the partition plate 17, pushing the permanent magnet 36 to disengage. The magnetic field is removed, and the main sealing piston plate 35 is pushed to slide on the outside of the heating tube mechanism 20. The piston sealing ring 38 slides on the outside of the heating tube mechanism 20. The outer side of the heating tube mechanism 20 is scraped off and cleaned by the scraper cone 39. Combined with electromagnetic induction, when water flows through the magnetic field, the calcium and magnesium ions in the water, the main components of scale, are magnetized, changing their crystal form from hard calcite to loose aragonite, making them less likely to adhere to the vessel wall. The resulting soft scale is scraped off by the scraper cone 39 and discharged with the water flow. This allows for daily water draining and cleaning after operation, achieving self-cleaning of scale, indirectly improving heating efficiency, saving energy, and indirectly increasing service life. After cleaning, the high-temperature resistant solenoid valve 4... 3. The solenoid valve 19 inside the switching pipe 41 at the bottom is opened, and the solenoid valve 2 44 and the solenoid valve 19 inside the switching pipe 41 at the top are closed. At this time, water is injected into the bottom of the inner cavity of the heat-insulating inner liner 15, and the main sealing piston plate 35 is pushed upward. The water is guided through the top slot of the partition 17 to the inside of the fixed pipe 25, and finally discharged through the high-temperature resistant flexible pipe 14 and the suction ring frame 11, thus achieving the effect of cleaning the high-temperature resistant flexible pipe 14 and the suction ring frame 11. Finally, after the main sealing piston plate 35 reaches the position, the sealing pipe 31 and the fixed pipe 25 are inserted and reset to seal. The permanent magnet 36 is attracted to the magnetic position at the bottom of the partition 17, thereby realizing the cleaning, reset and rinsing operation of the structure, further increasing the use effect of the structure.

[0032] In another implementation scheme, such as Figures 1-4 As shown, four casters 3 are movably installed at the bottom of the insulated tank 1, and two handles are fixedly installed at the top of the insulated tank 1.

[0033] The casters 3 provide support for the movement of the insulated tank 1 and assist in operation through the handles, making it easy to move around the work site.

[0034] In another implementation scheme, such as Figures 1-5 As shown, the outer side of the partition ring 16 is fixedly fitted onto the inner wall of the insulation tank 1. The float level controller 33 is located at the bottom of the partition ring 16. A Roots vacuum pump 22 is fixedly installed on the top of the partition ring 16. The input end of the Roots vacuum pump 22 passes through the partition ring 16 via a pipe and connects to the bottom of the partition ring 16. The position of the input end of the Roots vacuum pump 22 is higher than the position of the float level controller 33. The output end of the Roots vacuum pump 22 is connected to an exhaust pipe 12, which is fixed. A connecting pipe 21 is fixedly sleeved inside the top of the heat-insulating inner liner 15, extending through the heat-insulating tank 1 and to the outside of the heat-insulating tank 1. The bottom end of the connecting pipe 21 is fixedly inserted through the heat-insulating inner liner 15 and the spacer ring 16 and extends to the bottom of the spacer ring 16. The bottom of the connecting pipe 21 is connected to a spiral coil 23, which is sleeved on the outside of the heat-insulating inner liner 15. The bottom end of the spiral coil 23 is connected to the bottom of the inner cavity of the heat-insulating inner liner 15, and the top end of the connecting pipe 21 is connected to the top of the storage cone 28.

[0035] When steam ironing is performed using the handheld steam nozzle 10, the Roots vacuum pump 22 is activated. A negative pressure is created at the bottom of the partition ring 16, on the opposite side of the insulation inner liner 15 and the insulation tank 1. The airflow is introduced through the connecting pipe 21 and through the spiral coil 23 into the water on the opposite side of the insulation tank 1 and the insulation inner liner 15. The airflow through the connecting pipe 21 passes through the location of the insulation inner liner 15 and the storage cone 28, and enters through the guide hole 30 at the top of the storage cone 28, and is introduced through the interior of the guide hole 29. At this time, the airflow is introduced through the opposite side of the protective corrugated pipe 9 and the high-temperature resistant flexible pipe 14. The airflow first enters through the holes in the suction ring frame 11, and as the handheld steam nozzle 10 performs steam ironing, excess steam is expelled through the suction ring frame 11. Airflow is drawn in through the perforation, entering through the interlayer between the protective corrugated pipe 9 and the high-temperature resistant flexible pipe 14. The airflow enters the interior of the storage cone 28 through the first guide hole 29, and then enters the space between the storage cone 28 and the heat-insulating inner liner 15 through the second guide hole 30. At this time, the airflow is introduced into the interior of the spiral coil 23 through the connecting pipe 21. The recovered steam is immersed in water and condensed in the spiral coil 23, realizing the recovery and condensation of redundant steam. The excess heat is used to assist in heating the water flow on the opposite side of the heat-insulating tank 1 and the heat-insulating inner liner 15, increasing the water temperature and reducing the energy required for heating and evaporation of the heating tube mechanism 20, thereby achieving energy saving and environmental protection. It avoids the problem of excessive steam interfering with the view and increasing the humidity of the environment too much, and does not affect the ironing effect.

[0036] In another implementation scheme, such as Figures 3-8 As shown, one end of the inlet pipe 26 bypasses the float level controller 33 and extends to the inner side of the top of the heat-insulating inner liner 15 after passing through the partition ring 16. The bottom end of the connector 37 is fixedly inserted through the partition plate 17 and connected to the bottom of the partition plate 17. The permanent magnets 36 are evenly distributed in a circle on the top of the main sealing piston plate 35, and a ferromagnetic ring plate adapted to the permanent magnets 36 is fixedly installed at the bottom of the partition plate 17. The top of the permanent magnets 36 is slightly higher than the top of the main sealing piston plate 35.

[0037] The inlet pipe 26 guides the water flow into the connector 37, and through the connector 37, it guides the water to the opposite side of the main sealing piston plate 35 and the partition plate 17. The height of the permanent magnet 36 leaves a certain gap between the main sealing piston plate 35 and the partition plate 17, which facilitates the water flow through the connector 37 to enter the opposite side of the main sealing piston plate 35 and the partition plate 17 for pressurization, thereby expanding the structure. The magnetism of the permanent magnet 36 helps to fix the main sealing piston plate 35, and together with the piston sealing ring 38 and the sliding of the heating tube mechanism 20, it stabilizes the working position of the main sealing piston plate 35, facilitating auxiliary operation and maintaining stability of the structure.

[0038] In another implementation scheme, such as Figures 1-8As shown, one of the two switching tubes 41 at the top is connected to the inside of the threaded groove 24, and the other of the two switching tubes 41 at the bottom is connected to the bottom of the inner cavity of the heat-insulating inner liner 15. The threaded groove 24 is distributed in a spiral pattern on the inner wall of the heat-insulating inner liner 15. The three guide holes 34 are evenly distributed in a spiral pattern inside the heat-insulating inner liner 15. The two ends of the three guide holes 34 are connected to the threaded groove 24 and the inside of the heat-insulating inner liner 15, respectively.

[0039] The two switching pipes 41 have similar structures and functions, but the directions of output are different. One leads into the threaded groove 24, and the other leads into the bottom of the inner cavity of the insulation liner 15. The water flowing into the threaded groove 24 is sprayed into the insulation liner 15 through the guide hole 34, which can achieve uniform cleaning and uniform filling during the water filling process to avoid local water accumulation and low temperature, thus stabilizing the operation. When it is necessary to lift the main sealing piston plate 35 by water pressure, the switching pipe 41 leading into the insulation liner 15 is connected. The bottom of the main sealing piston plate 35 and the inside of the insulation liner 15 are pressurized through the switching pipe 41, thereby lifting the main sealing piston plate 35 to facilitate the operation of the structure.

[0040] In another implementation scheme, such as Figures 1-10 As shown, the top of the heating tube mechanism 20 is fixedly installed on the top of the partition plate 17, and the bottom end of the heating tube mechanism 20 is fixedly installed on the bottom of the inner cavity of the heat-insulating inner liner 15. The piston sealing ring 38 is movably sleeved on the outside of the heating tube mechanism 20, and the shovel cone 39 is movably sleeved on the outer wall of the heating tube mechanism 20. The bottom of the main sealing piston plate 35 is fixedly installed with a main shovel cone, which is movably sleeved inside the heat-insulating inner liner 15. The heating tube mechanism 20 includes an austenitic stainless steel tube 20. 01. The porous ceramic heat insulation tube layer 2002 and the electromagnetic heating coil 2003 are fixedly sleeved on the inner wall of the austenitic stainless steel tube 2001. The electromagnetic heating coil 2003 is fixedly installed inside the porous ceramic heat insulation tube layer 2002. The electromagnetic heating coil 2003 is evenly distributed in a spiral pattern on the inner side of the porous ceramic heat insulation tube layer 2002. The heating tube mechanism 20 is evenly distributed in a circumferential linear pattern inside the heat insulation inner liner 15.

[0041] The top and bottom of the heating tube mechanism 20 reinforce the partition 17 and the insulation liner 15. The shovel cone 39 removes scale from the outside of the austenitic stainless steel tube 2001. The main shovel cone moves with the main sealing piston plate 35 to remove scale from the inner wall of the insulation liner 15. The porous ceramic heat insulation tube layer 2002 insulates the austenitic stainless steel tube 2001 and the electromagnetic heating coil 2003 without affecting the electromagnetic heating effect, thus protecting the working environment of the electromagnetic heating coil 2003. The electromagnetic heating coil 2003 is located at the bottom and middle of the porous ceramic heat insulation tube layer 2002 and the austenitic stainless steel tube 2001, preventing overheating at the top from affecting the sealing effect of the piston sealing ring 38. Electromagnetic heating ensures heating efficiency and achieves stable heat exchange, indirectly achieving energy saving. The austenitic stainless steel tube 2001 is a 310S stainless steel tube.

[0042] In another implementation scheme, such as Figures 1-9 As shown, the water supply pipe 6 is fixedly inserted through the heat preservation tank 1 and connected to the interior of the storage cone 28. The second guide hole 30 is evenly distributed in a circle on the top of the storage cone 28. The protective bellows pipe 9 is fixedly inserted through the storage cone 28 and extends to the outside of the heat preservation tank 1. The bottom end of the protective bellows pipe 9 is fixedly installed at the bottom of the inner cavity of the storage cone 28. The first guide hole 29 is evenly distributed in a circle inside the protective bellows pipe 9. The top end of the docking sealing pipe 31 is movably inserted through the partition 17 and extends to the inside of the fixed pipe 25. The partition 17 has a slot that matches the docking sealing pipe 31. The top end of the docking sealing pipe 31 is sealed and inserted into the interior of the fixed pipe 25. The bottom end of the fixed pipe 25 is fixedly installed on the top of the partition 17.

[0043] When the suction ring 11 assists in absorbing airflow and steam during ironing, the absorbed airflow may contain lint and short fibers. These lint and short fibers are then introduced into the storage cone 28 through the guide hole 29. At this time, a certain amount of water is injected into the storage cone 28 by opening the valve through the water inlet pipe 6, and the valve of the water inlet pipe 6 is closed. The airflow, through the water flow, leaves the lint and fibers behind, achieving a certain anti-clogging effect. Combined with backwashing after cleaning, this cleans the area between the protective corrugated pipe 9 and the high-temperature resistant flexible pipe 14, reducing blockage and indirectly improving the work efficiency. Maintaining cleanliness is beneficial for stable heat exchange, indirectly increasing energy savings. After cleaning, the high-temperature resistant solenoid valve 43 and the internal solenoid valve of the switching pipe 41 at the bottom... Valve 19 is opened, and solenoid valve 2 44 and solenoid valve 19 located inside the top switching pipe 41 are closed. At this time, water is injected into the bottom of the inner cavity of the heat-insulating inner liner 15, and pushes the main sealing piston plate 35 upward. The water flow is guided through the top slot of the partition 17 to the inside of the fixed pipe 25, and finally discharged through the high-temperature resistant flexible pipe 14 and the suction ring frame 11, thus achieving the effect of cleaning the high-temperature resistant flexible pipe 14 and the suction ring frame 11. Finally, after the heat-insulating main sealing piston plate 35 reaches the position, the sealing pipe 31 and the fixed pipe 25 are inserted to reset the seal. The permanent magnet 36 is attracted to the magnetic position at the bottom of the partition 17, thereby realizing the cleaning, reset and rinsing operation of the structure, further increasing the use effect of the structure.

[0044] In another implementation scheme, such as Figures 1-5 As shown, a discharge pipe 5 is connected to one side of the storage cone 28. The discharge pipe 5 is fixedly inserted through the heat-insulating inner liner 15 and extends to the outside of the heat-insulating tank 1. A discharge pipe 4 is connected to the bottom end of the heat-insulating inner liner 15. The discharge pipe 4 is fixedly inserted through the heat-insulating inner liner 15 and extends to the outside of the heat-insulating tank 1. Valves are provided inside the discharge pipe 4, the discharge pipe 5 and the water filling pipe 6.

[0045] The function of the outlet pipe 5 is to open the valve to discharge the water added to the inside of the storage cone 28 by the water inlet pipe 6, thereby facilitating the cleaning of the structure. The valve of the outlet pipe 4 is opened to facilitate the discharge and cleaning of the inside of the heat-insulating inner liner 15. Together with the water inlet pipe 6 to add water to the inside of the storage cone 28, it increases the convenience of cleaning, facilitates multi-angle cleaning of the inside of the structure, reduces scale, and increases the heat exchange effect of the structure.

[0046] In another implementation scheme, such as Figures 1-4 As shown, the high-temperature resistant flexible tube 14 is a fluororubber reinforced composite flexible tube. The inner layer of the high-temperature resistant flexible tube 14 is fluororubber, and the outer layer of the high-temperature resistant flexible tube 14 is covered with fiberglass cloth. The bottom of the suction ring frame 11 is connected to the top of the high-temperature resistant flexible tube 14, and the top of the protective corrugated tube 9 is connected to the bottom of the handheld steam nozzle 10. Several small connecting holes are opened inside both the handheld steam nozzle 10 and the suction ring frame 11.

[0047] The high-temperature resistant flexible tube 14 uses an inner layer of fluororubber with a temperature resistance of 200-260℃ and an outer layer of glass fiber braiding to enhance its explosion resistance. It has excellent overall flexibility and can be folded and bent. The fluororubber is resistant to steam corrosion and has strong chemical resistance. It is easy for operators to operate the handheld steam nozzle 10 by hand through the protective corrugated tube 9, which increases the relative stability of the structure and facilitates flexible operation. The small holes of the handheld steam nozzle 10 and the suction ring frame 11 stably guide the steam, which facilitates the operation.

[0048] In another implementation scheme, such as Figure 1 As shown, a control panel 2 is fixedly installed on the outside of the insulated tank 1.

[0049] Control panel 2 is equipped with an intelligent control system and an internal intelligent controller. The hardware includes a display screen and operation buttons, which facilitates the operation of the equipment by the operator.
