Description

Technical Field

[0001] This utility model relates to the field of ramie cleaning and processing technology, and in particular to a wastewater recycling device for ramie cleaning. Background Technology

[0002] During cultivation, ramie fibers often accumulate impurities such as soil and dust, which reduce fiber quality and spinnability. Therefore, washing is the first step in ramie processing, aiming to remove these impurities and ensure smooth subsequent processing. Currently, ramie washing primarily involves soaking, which uses a large amount of water. Therefore, most manufacturers equip their washing tanks with a circulating filtration system to circulate and filter the water.

[0003] Chinese patent CN221777603U discloses a wastewater recycling device. This device, by setting up a guide rail box, servo motor, threaded column, upper and lower plates and fixing rod, can more easily separate the upper tank and lower tank, thereby facilitating the cleaning of the filter structure and reducing the workload of operators.

[0004] However, the device still has shortcomings: larger impurities trapped by the device accumulate on the activated carbon box. When the water consumption is large, it is easy to cause excessive accumulation of impurities. Therefore, the staff needs to stop the machine frequently and clean the accumulated material on the surface of the activated carbon box, which affects the efficiency of washing large batches of ramie.

[0010] And a collection bucket, which is set above the hollow column by a bracket. The output end of the collection bucket is connected to the water inlet pipe. The collection bucket is equipped with a squeezing mechanism for the impurities accumulated on the coarse filter screen.

[0011] Preferably, a central column is provided inside the water storage chamber, and UV lamps are arranged in a ring array around the axis of the central column on its outer wall. A spiral plate coaxial with the central column is provided on the arc surface of the central column. The side of the spiral plate away from the central column is connected to the inner wall of the water storage chamber to form a serpentine channel inside the water storage chamber. The output end of the filter cartridge is connected to the input end of the serpentine channel.

[0012] Preferably, it also includes a water pump, with a pumping pipe at the input end of the water pump and the other end of the pumping pipe connected to the output end of the serpentine channel.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] By using a hollow column with an inlet pipe, slag discharge pipe, feed pipe, and air inlet pipe arranged in a ring array, and a spherical groove inside the hollow column containing spheres with cylindrical holes, the device achieves primary filtration of wastewater when the cylindrical holes are connected to the inlet and feed pipes.

Detailed Implementation

[0025] Example 1

[0026] like Figures 1-5As shown, this utility model proposes a wastewater recycling device for ramie washing, comprising a fine filter barrel 1, a filter cylinder 4, a hollow column 9, a sphere 14, and a collection bucket 17. The fine filter barrel 1 is provided with a water storage chamber 101 and a locking hole 102 communicating with the water storage chamber 101 from the top. Several UV lamps 201 are installed inside the water storage chamber 101. The filter cylinder 4 is movably connected to the fine filter barrel 1 and is adapted to the locking hole 102. A fine filtration assembly is installed inside the filter cylinder 4. The fine filtration assembly includes a filter membrane 5 and an activated carbon pack 6. The filter membrane 5 is disposed inside the filter cylinder 4 and adheres to the bottom surface of its inner cavity. The activated carbon pack 6 is located in the inner cavity of the filter cylinder 4 and rests on the filter membrane 5. The filter membrane is, but is not limited to, an ultrafiltration membrane. A hollow column 9 is mounted above the fine filter barrel 1 via a bracket. A spherical groove 901 is provided inside the hollow column 9. An inlet pipe 10, a slag discharge pipe 11, a feed pipe 12, and an air inlet pipe 13, all connected to the spherical groove 901, are mounted on the hollow column 9. The inlet pipe 10 is opposite to the feed pipe 12, and the slag discharge pipe 11 is opposite to the air inlet pipe 13. The feed pipe 12 is connected to the input end of the filter cylinder 4. An internally threaded pipe 8 is fitted onto the feed pipe 12 and is spirally connected to it. The end of the internally threaded pipe 8 away from the hollow column 9 is coaxially connected to a pressure cap 7. The pressure cap 7 is inserted into a locking hole 102 and fits against the upper end face of the filter cylinder 4. The pressure cap 7 has a through hole connecting the internally threaded pipe 8 and the input end of the filter cylinder 4. A sphere 14 is positioned within a spherical groove 901 and adheres to its inner wall. A cylindrical hole 141 is provided on the sphere 14, and a coarse filter screen 15 is installed within the cylindrical hole 141. Two mounting shafts are symmetrically arranged on the sphere 14 about its center, and both mounting shafts are rotatably connected to a hollow column 9. A drive assembly for rotating the sphere 14 is provided on the hollow column 9. The drive assembly includes, but is not limited to, a servo motor 16. The body of the servo motor 16 is connected to the hollow column 9, and the output end of the servo motor 16 is connected to one of the mounting shafts. When the sphere 14 is rotating, the opening of the cylindrical hole 141 is sequentially connected to a water inlet pipe 10, a slag discharge pipe 11, a material discharge pipe 12, and an air inlet pipe 13. A collection bucket 17 is mounted above the hollow column 9 via a bracket. A feed pipe 18 is provided on the collection bucket 17 and communicates with its interior. The output end of the collection bucket 17 is connected to the water inlet pipe 10. A squeezing mechanism for extruding impurities accumulated on the coarse filter screen 15 is provided inside the collection bucket 17. The extrusion mechanism includes a pressure plate 21 and a lifting drive assembly, which includes, but is not limited to, a cylinder 22. A guide tube 19 is provided at the bottom of the upper cover of the collection hopper 17, and a movable rod 20 is installed inside the guide tube 19. The pressure plate 21 is connected to the end of the movable rod 20 away from the upper cover of the collection hopper 17. The body of the cylinder 22 is mounted on the collection hopper. The cylinder 22 is connected to an air tank and an air compressor. The air tank and air compressor are common structures and will not be described in detail. Two air pipes are provided at the output end of the air tank, connecting the cylinder 22 and the air inlet pipe 13 respectively. Each of the two air pipes is equipped with a solenoid valve. The output end of the cylinder 22 is inserted into the guide tube 19 and connected to the movable rod 20. In the working state, the cylinder 20 drives the movable rod 20 to slide axially along the guide tube 19. The outer diameter of the pressure plate 21 is the same as the inner diameter of the water inlet pipe 10 and the inner diameter of the cylindrical hole 141.

[0027] In this embodiment, the feed pipe 18 is connected to the drain pipe of the cleaning tank, and the servo motor 16 is started. The servo motor 16 drives the ball 14 to rotate to the feed port of the cylindrical hole 141 and connect with the water inlet pipe 10. At this time, the discharge port of the cylindrical hole 141 is connected with the discharge pipe 12. Wastewater enters the cylindrical hole 141 along the feed pipe 18, the collection bucket 17, and the water inlet pipe 10. Larger impurities are intercepted by the coarse filter screen 15, and the remaining wastewater mixture flows down and enters the filter cartridge 4. The wastewater is filtered twice by the activated carbon bag 6 and the filter membrane 5. Fine impurities are intercepted, and the clean water flows down and is stored in the fine filter tank 1. The water in the water storage chamber 101 is disinfected and sterilized after being irradiated by the ultraviolet lamp emitted by the UV lamp tube 201. The water pump 23 pumps the water that has been filtered twice back into the cleaning tank to realize the recycling of water. The start-stop time cycle of the servo motor 16 and cylinder 22 is set according to the turbidity of the water in the washing tank during the ramie washing process. When the set time node is reached, the cylinder starts first and pushes the pressure plate 21 down into the cylindrical hole 141. The pressure plate 21 squeezes the impurities trapped on the coarse filter screen 15, reducing the moisture content of the impurities. Then, the pressure plate 21 moves upward into the water inlet pipe 10, cutting off the water in the collection bucket 17 from entering the cylindrical hole 141. Then, the servo motor 16 drives... The sphere 14 rotates until the feed inlet of the cylindrical hole 141 connects with the slag discharge pipe 11. At this time, the output end of the cylindrical hole 141 is aligned with the air inlet pipe 13. The high-pressure air in the air tank is blown out through the air pipe and the air inlet pipe 13. The high-speed air jet blows the impurities trapped by the coarse filter screen 15 in the cylindrical hole 141 out of the slag discharge pipe 11, and at the same time washes and unclogs the coarse filter screen 15. Then, the servo motor 16 drives the sphere to rotate and reset, and the cylinder 22 drives the pressure plate 21 to rise and reset. When it is necessary to clean the inside of the filter cartridge 4, the internal threaded pipe 8 is rotated to drive the pressure cover 7 to rise during the blowing of air into the cylindrical hole 141. Then, the filter cartridge 4 is taken out for cleaning, or a spare can be directly replaced.

A central column 2 is set in the water storage chamber 101. UV lamps 201 are arranged in a ring array around the axis of the central column 2 on its outer wall. A spiral plate 3 coaxial with the central column 2 is set on the arc surface of the central column 2. The side of the spiral plate 3 away from the central column 2 is connected to the inner wall of the water storage chamber 101 to form a serpentine channel in the water storage chamber 101. The output end of the filter cartridge 4 is connected to the input end of the serpentine channel. A water pump pipe is set at the input end of the water pump 23, and the other end of the water pump pipe is connected to the output end of the serpentine channel.

[0030] In this embodiment, the spiral channel can extend the flow distance of the water, thereby prolonging the time it is irradiated by the UV lamp tube 201 during the flow process and improving the sterilization efficiency.
