Description

Technical Field

[0001] This utility model relates to the field of fabric dyeing and finishing technology, specifically to a stirring structure of a heat recovery device for a fabric dyeing machine. Background Technology

[0002] The wastewater from dyeing machines is very hot. Traditional dyeing machines typically discharge this hot wastewater directly or cool it down before discharge. This high-temperature discharge wastes energy and increases carbon emissions. Furthermore, the washing process in fabric dyeing and finishing requires hot water. Traditional dyeing machines heat the water before pumping it into the tank for the washing function, requiring the heating of large quantities of water and consuming significant energy. This situation of discharging hot wastewater while simultaneously heating cold water results in substantial energy loss and hinders cost savings for businesses. Therefore, it is necessary to recover the wastewater's residual heat. To address the aforementioned shortcomings, the patent with application number 202223409744.8 in the disclosed technology was applied. It includes a dyeing machine body and a heat exchange tank. The dyeing machine body is connected to a wastewater main pipe, one end of which is connected to the inlet of a water pump. The outlet of the water pump is connected to the top of the heat exchange tank through a wastewater inlet pipe. Although the stirring mechanism can stir the clean water to make the heat exchange between the clean water and the wastewater more uniform, the stirring structure inside the device is relatively weak. The stirring range of the clean water to be heated inside the tank is relatively limited, which is not conducive to the high-quality and uniform heating of the clean water inside the tank. Utility Model Content

[0003] The purpose of this utility model is to provide a stirring structure for a heat recovery device of a fabric dyeing machine, so as to solve the problem mentioned in the background art that although the stirring mechanism can stir the water to make the heat exchange between the water and the wastewater more uniform, the stirring structure inside the device is relatively weak and the stirring range of the water to be heated inside the tank is relatively limited, which is not conducive to the high-quality and uniform heating of the water inside the tank.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stirring structure for a heat recovery device of a fabric dyeing machine, comprising a tank, a motor fixedly connected to the top center of the tank, a rotating rod fixedly connected to the bottom end of the motor, the rotating rod being rotatably connected to the tank through a sealed bearing, a spiral tube provided on the outer side of the rotating rod, the spiral tube being fixedly connected to the contact surface of the tank, a stirring assembly provided on the outer side of the spiral tube, a threaded tube provided below the center of the tank, a valve provided at the bottom end of the threaded tube, and a collar fixedly fitted below the outer wall of the threaded tube, the collar abutting against the contact surface of the tank;

[0005] The stirring assembly includes a support plate, a vertical rod, stirring blades, a ring plate, a circular groove plate, bolts, a toothed ring plate, and a toothed ring.

[0006] Two support plates are respectively fixed to the left and right sides of the bottom of the outer wall of the rotating rod. A vertical rod is rotatably connected to the outer side of the upper surface of the support plate. Multiple stirring blades are fixed in a ring from top to bottom on the outer wall of the vertical rod. A ring plate is rotatably connected to the lower part of the outer wall of the vertical rod. A circular groove plate is rotatably connected to the outer side of the ring plate. Two bolts are inserted from bottom to top on the left and right sides of the inner wall of the circular groove plate. The bolts pass through the circular groove plate and can be threaded to the inner wall of the tank. A toothed ring plate is fixed to the bottom of the vertical rod. A toothed ring is engaged with the outer side of the toothed ring plate. The outer wall of the toothed ring is fixedly connected to the inner wall of the circular groove plate. The contact surface of the circular groove plate is threaded to the threaded pipe.

[0007] Preferably, the outer wall of the threaded tube is wrapped with PTFE tape.

[0008] Preferably, the top of the outer wall of the threaded tube has a tapered structure.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the stirring structure of the heat recovery device of the fabric dyeing machine has the following advantages over traditional technology:

[0010] Through the coordination of the tank, motor, spiral tube, rotating rod, stirring assembly, threaded pipe, valve, and collar, the operator first injects an appropriate amount of clean water into the tank. Subsequently, when the spiral tube contains dyeing wastewater with a higher temperature, the rotating rod rotates when the motor is powered on. During this process, the support plates on both sides, the vertical rod, and multiple stirring blades revolve around the rotating rod. The stirring blades can stir the clean water inside the tank, allowing it to evenly absorb the heat from the wastewater inside the spiral tube. At the same time, due to the meshing connection between the toothed ring plate and the toothed ring, the toothed ring plate and the vertical rod can rotate on their own, and multiple stirring blades can revolve around the rotating rod while also rotating around the vertical rod. This can significantly increase the stirring range of the clean water inside the tank, which is conducive to the high-quality and uniform heating of the clean water inside the tank.

The output shaft of the motor 2 is fixedly connected to a rotating rod 4. The power cord of the motor 2 is connected to an external power supply device. The rotating rod 4 is fixedly connected to the bottom of the motor 2, and the rotating rod 4 is connected to a sealed bearing. Tank 1 is rotatably connected. A spiral tube 3 is provided on the outside of the rotating rod 4. Dyeing wastewater can be supplied through the spiral tube 3. The spiral tube 3 is fixedly connected to the contact surface of tank 1. A stirring assembly 5 is provided on the outside of the spiral tube 3. A threaded tube 6 is located below the center of the inside of tank 1. A valve 7 is located at the bottom end of the threaded tube 6. A collar 8 is fixedly fitted onto the lower outer wall of the threaded tube 6, and the collar 8 abuts against the contact surface of tank 1. The stirring assembly 5 includes a support plate 501, a vertical rod 502, a stirring blade 503, a ring plate 504, a circular groove plate 505, a bolt 506, a toothed ring plate 507, and a toothed ring 508. Two support plates 501... The support plate 501 is rotatably connected to the outer side of the upper surface of the support plate 501, with vertical rods 502 rotatably connected to the bottom of the outer wall of the vertical rod 502 in a ring shape from top to bottom. A ring plate 504 is rotatably connected to the lower part of the outer wall of the vertical rod 502. The vertical rod 502 is rotatably connected to the ring plate 504 via a sealed bearing. A circular groove plate 505 is rotatably connected to the outer side of the ring plate 504. The ring plate 504 is rotatably connected to the circular groove plate 505 via a sealed bearing. Two bolts 506 are inserted from bottom to top on the left and right sides of the inner wall of the circular groove plate 505, penetrating the circular groove plate 505. The vertical rod 502 is threaded to the inner wall of the tank 1. A toothed ring plate 507 is fixedly connected to the bottom end of the vertical rod 502. A toothed ring 508 is engaged with the outer side of the toothed ring plate 507. The outer wall of the toothed ring 508 is fixedly connected to the inner wall of the circular groove plate 505. The circular groove plate 505 is threaded to the contact surface of the threaded pipe 6. The outer wall of the threaded pipe 6 is clearance-fitted with the through surface of the tank 1. Teflon tape is wrapped around the upper part of the outer wall of the threaded pipe 6 to facilitate the sealing of the threaded connection between the threaded pipe 6 and the circular groove plate 505. The top of the outer wall of the threaded pipe 6 is a conical structure. The conical structure facilitates the threaded pipe 6 to pass through the tank 1 and be threaded to the circular groove plate 505.

[0018] The stirring structure of the heat recovery device for the fabric dyeing machine operates as follows: First, the operator injects an appropriate amount of clean water into the tank 1. Then, when high-temperature dyeing wastewater flows inside the spiral tube 3, power is supplied to the motor 2, causing the rotating rod 4 to rotate. During this process, the side support plates 501, vertical rods 502, and multiple stirring blades 503 revolve around the rotating rod 4. The stirring blades 503 agitate the clean water inside the tank 1, ensuring even absorption of heat from the wastewater inside the spiral tube 3. Simultaneously, due to the interaction between the toothed ring plate 507 and the toothed ring 508... The meshing connection allows the toothed ring plate 507 and the vertical rod 502 to rotate on their own, and the multiple stirring blades 503 can revolve around the rotating rod 4 and rotate around the vertical rod 502 at the same time. This can greatly improve the stirring range of the clean water inside the tank 1, which is conducive to the high-quality and uniform heating of the clean water inside the tank 1. After the water temperature inside the tank 1 rises to a certain value, the lower valve 7 is opened to discharge the warm water for use. Then, room temperature clean water is injected into the tank 1 again to continue the heat absorption operation of the high-temperature wastewater passing through the spiral tube 3.
