Description

Technical Field

[0001] This invention relates to the field of dyeing wastewater treatment technology, specifically to an environmentally friendly wastewater recycling device for dyeing equipment and its processing technology. Background Technology

[0002] Due to the irregular shape of the products, bamboo, wood and rattan handicrafts usually require the use of roller dyeing equipment for dyeing during production. At the same time, in order to meet environmental protection requirements, environmentally friendly reactive dyes with low toxicity are usually selected. However, the dyeing process of these dyes requires the addition of auxiliaries such as soda ash and sodium sulfate, which generates a large amount of high-salt and alkaline wastewater. If discharged directly, it will cause serious environmental pollution, so it must be treated.

[0003] Currently, the treatment of high-salt and alkaline wastewater typically employs reverse osmosis membrane technology. A high-pressure pump pressurizes the wastewater and transports it to the reverse osmosis membrane module for desalination and purification. However, when the neutralized wastewater enters the high-pressure pump of the reverse osmosis membrane system through the outlet pipe, salt precipitates and crystallizes on the inner wall of the pipe, causing a reduction in the pipe's inner diameter and an increase in water flow velocity. This abnormal flow velocity disrupts the stability of the reverse osmosis membrane's feed pressure, reducing the overall wastewater treatment effect. Furthermore, the crystals adhering to the inner wall of the pipe are difficult to clean in a timely manner, easily leading to pipe blockages and other malfunctions, thus affecting the stability of the wastewater treatment process.

[0004] To address the above issues, an environmentally friendly wastewater recycling device for dyeing equipment and its processing technology are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an environmentally friendly wastewater recycling device for dyeing equipment and its processing technology. By using this invention, the problem in the background that salt precipitation easily forms crystals on the inner wall of the outlet pipe during dyeing wastewater treatment, thus affecting the wastewater treatment effect is solved.

The third water pump is installed on one side of the multi-media filter, and the outlet of the third water pump is connected to the third inlet pipe. A security filter is connected to one end of the third inlet pipe, and the outlet pipe is connected to the bottom of the security filter.

[0011] Furthermore, the compensation component includes a fixing ring fixedly connected to the outer wall of the water outlet pipe. Two electric push rods are installed opposite each other on one side of the fixing ring. The movable ends of the two electric push rods are fixedly connected to a sliding sleeve. The sliding sleeve is slidably connected to the water outlet pipe. A number of elastic plates are evenly connected to one end of the sliding sleeve. Rubber strips are fixedly connected between the elastic plates. A sealing gasket is fixedly connected to the outer wall of the water outlet pipe.

[0013] Furthermore, the drive assembly includes a U-shaped mounting plate fixedly connected to the outer wall of the water outlet pipe, a second motor mounted on the top of the U-shaped mounting plate, a second rotating shaft fixedly connected to the output end of the second motor, a gear fixedly connected to the outer wall of the second rotating shaft, a protective shell fixedly connected to the outer wall of the water outlet pipe, a magnetic rotor rotatably connected to the inner wall of the water outlet pipe, a permanent magnet rotor rotatably connected to the outer wall of the water outlet pipe, a gear ring fixedly connected to the outer wall of the permanent magnet rotor, and the gear meshing with the gear ring.

[0014] Furthermore, the cleaning component includes a mounting rod fixedly connected inside the magnetic rotor, a third rotating shaft fixedly connected to one side of the mounting rod, several connecting rods fixedly connected to the outer wall of the third rotating shaft, a scraper fixedly connected to one end of the connecting rod, the scraper being in contact with the inner wall of the water outlet pipe, and a rotating rod fixedly connected to the outer wall of the third rotating shaft, the rotating rod being rotatably connected to the inner wall of the water outlet pipe.

[0019] S3: The neutralization component neutralizes and coagulates / sediments the pretreated wastewater;

[0020] S4: The filter components sequentially remove larger particulate impurities and suspended solids, organic matter, and some colloids and tiny particles from the wastewater;

[0021] S5: The reverse osmosis module desalinates high-salt wastewater, and the treated water is then recycled.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] When the diameter of the outlet pipe shrinks due to salt crystallization on the inner wall, the compensation component dynamically increases the pipe diameter to stabilize the wastewater flow rate at the baseline value, ensuring that the flow rate entering the reverse osmosis component meets the treatment requirements and avoids affecting the filtration effect.

[0024] The drive component rotates the cleaning component, which can promptly scrape off the crystals formed on the inner wall of the water outlet pipe due to salt precipitation, preventing the continuous accumulation of crystals from reducing the inner diameter of the pipe and ensuring smooth flow of wastewater in the pipe.

[0025] After the cleaning component scrapes off the crystals, the grinding component grinds the crystals into fine particles, which are then carried by the water flow into subsequent treatment stages, preventing crystal buildup and blockage of the pipes.

[0026] The drive component adopts a contactless magnetic coupling drive method, which can maintain the overall sealing of the water outlet pipe while driving the cleaning component to work, thus avoiding wastewater leakage. Attached Figure Description

[0039] 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.

[0040] To address the technical problem of salt crystal formation and adhesion on the inner wall of the effluent pipe 5 during dyeing wastewater treatment, which affects the wastewater treatment effect, such as... Figures 1-11 As shown, the following preferred technical solutions are provided:

[0041] An environmentally friendly wastewater recycling device for dyeing equipment and its processing technology include a drum dyeing machine 1, which can dye bamboo, wood, and rattan. The drum dyeing machine 1 is existing technology and will not be described in detail here. A controller is installed on one side of the drum dyeing machine 1 to control various electrical devices. The controller is also existing technology and is not shown in the figure. A pretreatment component 2 is connected to the bottom of the drum dyeing machine 1. The pretreatment component 2 can filter large particulate suspended matter such as fibers. A neutralization component 3 is connected to one side of the pretreatment component 2. The neutralization component 3 can neutralize high-salt and alkaline wastewater and facilitate coagulation and sedimentation of the neutralized wastewater. A filter component 4 is connected to one side of the neutralization component 3. The filter component 4 can sequentially remove larger particulate impurities and suspended matter, organic matter, some colloids, and small particles. A water outlet pipe 5 is connected to the bottom of the filter component 4. A compensation component 6 is connected to one end of the water outlet pipe 5. A water inlet pipe 7 is connected to one end of the compensation component 6, and a reverse osmosis component 9 is connected to the other end of the water inlet pipe 7. The reverse osmosis component 9 can desalinate high-salt wastewater. Figure 6 and Figure 8 As shown, an electromagnetic flow velocity sensor 8 is installed on the inlet pipe 7. The electromagnetic flow velocity sensor 8 can easily detect the flow velocity of wastewater in the inlet pipe 7. During initial calibration, the electromagnetic flow velocity sensor 8, together with the controller, sets the normal flow velocity of wastewater to the reference value.

[0042] During operation, the high-salt wastewater from the dyeing machine 1 is discharged after dyeing. It passes through the pretreatment component 2 to filter out large suspended particles such as fibers. The wastewater then enters the neutralization component 3 to neutralize the high-salt wastewater. After neutralization, the wastewater undergoes coagulation and sedimentation. The supernatant is then pumped into the filtration component 4 to remove larger particles, suspended solids, organic matter, some colloids, and small particles. The high-salt wastewater then enters the reverse osmosis component 9 through the outlet pipe 5 and the compensation component 6 for desalination treatment. After desalination, the wastewater is discharged for recycling. When salt crystals form on the inner wall of the outlet pipe 5, the inner diameter of the pipe narrows, causing the wastewater flow rate inside the pipe to increase. At the same time, the electromagnetic flow rate sensor 8 detects the change in the wastewater flow rate in the outlet pipe 5. The controller then increases the diameter of the compensation component 6 to quickly stabilize the wastewater flow rate in the inlet pipe 7 at the baseline value, performing dynamic compensation of the wastewater flow rate to ensure that the flow rate entering the reverse osmosis component 9 always meets the treatment requirements, thereby avoiding affecting the filtration effect.

[0043] A drive assembly 10 is installed on one side of the outlet pipe 5. A cleaning assembly 20 is fixedly installed inside the drive assembly 10. The cleaning assembly 20 is attached to the inner wall of the outlet pipe 5. A grinding assembly 30 is installed inside the outlet pipe 5. The cleaning assembly 20 and the grinding assembly 30 are fixedly connected. When crystals are formed on the inner wall of the outlet pipe 5 due to salt precipitation, the controller causes the drive assembly 10 to drive the cleaning assembly 20 to rotate, which scrapes off the crystals on the inner wall of the outlet pipe 5 in time. This prevents the crystals from continuing to adhere and accumulate, which would cause the inner diameter of the pipe to shrink. This ensures smooth flow of wastewater in the pipe and reduces the risk of pipe blockage. The scraped crystals are ground into fine particles by the grinding assembly 30, which can then be easily carried into the subsequent treatment stage with the water flow. This prevents the crystals from accumulating and clogging the pipe, reduces wear on the pipe and subsequent equipment, and ensures the stable operation of the entire wastewater treatment process.

[0044] like Figures 1-2 As shown, the pretreatment component 2 includes a first drain pipe 21 connected to the bottom of the roller dyeing machine 1, and the other end of the first drain pipe 21 is connected to a filter box 22. A filter screen 23 is fixedly connected inside the filter box 22. A first water inlet pipe 24 is connected to one side of the filter box 22, and a first water pump 25 is connected to the other end of the first water inlet pipe 24. A first connecting pipe 26 is connected to the outlet of the first water pump 25.

[0045] like Figures 1-3 As shown, the neutralization component 3 includes a treatment tank 31 connected to one end of the first connecting pipe 26, a first water pump 25 installed on one side of the treatment tank 31, a first motor 32 installed on the top of the treatment tank 31, a first rotating shaft 33 fixedly connected to the output end of the first motor 32, the first rotating shaft 33 being rotatably connected to the treatment tank 31, a stirring rod 34 fixedly connected to the outer wall of the first rotating shaft 33, a drain pipe 35 connected to the bottom of the treatment tank 31, a valve provided on the drain pipe 35 for easy control of the opening and closing of the drain pipe 35, a second drain pipe 36 connected to one side of the treatment tank 31, and a second water pump 37 connected to the other end of the second drain pipe 36, the second water pump 37 installed on the outer wall of the treatment tank 31, a second water inlet pipe 38 connected to the outlet of the second water pump 37, and two medicine inlet pipes 39 connected to the top of the treatment tank 31.

[0046] like Figure 1 and Figures 3-4As shown, the filter assembly 4 includes a multi-media filter 41 connected to one end of the second inlet pipe 38. The multi-media filter 41 is used to remove larger particulate impurities and suspended solids in the wastewater. The multi-media filter 41 is existing technology and will not be described in detail here. A third drain pipe 42 is connected to one side of the multi-media filter 41, and a filter pipe 43 is connected to the other end of the third drain pipe 42. Activated carbon 44 is installed inside the filter pipe 43. The activated carbon 44 is used to remove organic matter and some colloids in the wastewater. A second connecting pipe 45 is connected to one end of the filter pipe 43, and a third water pump 46 is connected to the other end of the second connecting pipe 45. The third water pump 46 is installed on one side of the multi-media filter 41. The outlet of the third water pump 46 is connected to a third inlet pipe 47, and a security filter 48 is connected to one end of the third inlet pipe 47. The security filter 48 is used to remove small particles in the wastewater. The security filter 48 is existing technology and will not be described in detail here. The outlet pipe 5 is connected to the bottom of the security filter 48.

[0047] like Figure 1 , Figures 5-6 , Figure 8 and Figures 10-11 As shown, the compensation component 6 includes a fixing ring 61 fixedly connected to the outer wall of the outlet pipe 5. Two electric push rods 62 are installed opposite each other on one side of the fixing ring 61. The movable ends of the two electric push rods 62 are fixedly connected to a sliding sleeve 63. The sliding sleeve 63 is slidably connected to the outlet pipe 5. A number of elastic plates 64 are evenly connected to one end of the sliding sleeve 63. Rubber strips 65 are fixedly connected between the elastic plates 64. Both the elastic plates 64 and the rubber strips 65 are made of chemical corrosion resistant materials. The number of elastic plates 64 and the number of rubber strips 65 form a pipe. The pipe is connected to the sliding sleeve 63 and the inlet pipe 7 respectively. A sealing gasket 66 is fixedly connected to the outer wall of the outlet pipe 5. The inner wall of the sliding sleeve 63 is in contact with the sealing gasket 66.

[0048] like Figure 1 and Figures 5-6 As shown, the reverse osmosis assembly 9 includes a high-pressure pump 91 connected to the inlet pipe 7. The outlet of the high-pressure pump 91 is connected to a first branch pipe 92. A support frame 94 is provided on one side of the high-pressure pump 91. Two reverse osmosis membranes 93 are installed inside the support frame 94. The first branch pipe 92 is connected to the inlet of the reverse osmosis membrane 93. The outlet of the reverse osmosis membrane 93 is connected to a second branch pipe 95. The second branch pipe 95 facilitates the discharge of treated clean water for subsequent recycling. The impurity outlet of the reverse osmosis membrane 93 is connected to a third connecting pipe 96, which facilitates the discharge of high-concentration brine.

[0049] In operation, after the drum dyeing machine 1 completes the dyeing of bamboo, wood, and rattan, the controller causes the first water pump 25 to pump the generated high-salt-alkali wastewater through the first drain pipe 21 into the filter box 22. The wastewater is then filtered through the filter screen 23 to remove large suspended particles such as fibers. Subsequently, the wastewater is drawn by the first water pump 25 through the first inlet pipe 24 and enters the treatment tank 31 through the first connecting pipe 26. At this time, a neutralizing agent is added to the treatment tank 31 through one of the inlet pipes 39 to neutralize the high-salt-alkali wastewater. Then, a coagulant is added through the other inlet pipe 39 to coagulate and settle the neutralized wastewater. During the neutralization and coagulation process, the controller causes the first motor 32 to drive the first rotating shaft 33 and the stirring rod 34 to rotate, stirring the wastewater and the agent, thereby improving the efficiency of the process. The neutralization and coagulation process involves the wastewater undergoing coagulation and sedimentation. The resulting sludge is discharged through the bottom drain pipe 35, while the supernatant is drawn by the second pump 37 through the second drain pipe 36 and enters the multi-media filter 41 through the second inlet pipe 38 to facilitate the removal of larger particulate impurities in the wastewater. The wastewater is then drawn through the third drain pipe 42 by the third pump 46 into the filter pipe 43 filled with activated carbon 44 to remove organic matter and some colloids. Subsequently, the wastewater is drawn by the third pump 46 through the second connecting pipe 45 and enters the security filter 48 through the third inlet pipe 47 to remove fine particles. The treated high-salt wastewater then enters the reverse osmosis module 9 through the outlet pipe 5, the compensation component 6, and the inlet pipe 7 for desalination treatment before being discharged for subsequent recycling.

[0050] When salt crystals form on the inner wall of the outlet pipe 5, the inner diameter of the pipe decreases, causing the wastewater flow rate inside the pipe to increase. At the same time, the electromagnetic flow rate sensor 8 detects the change in the wastewater flow rate inside the outlet pipe 5. At this time, the controller causes the two electric push rods 62 to extend, pushing the sliding sleeve 63 to slide on the outer wall of the outlet pipe 5. This causes several elastic plates 64 at one end of the sliding sleeve 63 to open, and the rubber strips 65 between the elastic plates 64 to extend as well, realizing a dynamic increase in the pipe diameter. This quickly stabilizes the wastewater flow rate in the inlet pipe 7 at the reference value, performing dynamic compensation for the wastewater flow rate. This ensures that the flow rate entering the reverse osmosis component 9 always meets the treatment requirements, thereby avoiding affecting the filtration effect.

[0051] To address the technical problem of crystallization caused by salt precipitation being difficult to clean in a timely manner, such as... Figures 6-10 As shown, the following preferred technical solutions are provided:

[0052] like Figures 6-9As shown, the drive assembly 10 includes a U-shaped mounting plate 101 fixedly connected to the outer wall of the water outlet pipe 5. A second motor 102 is mounted on the top of the U-shaped mounting plate 101. A second rotating shaft 103 is fixedly connected to the output end of the second motor 102. A gear 104 is fixedly connected to the outer wall of the second rotating shaft 103. A protective shell 105 is fixedly connected to the outer wall of the water outlet pipe 5. A magnetic rotor 106 is rotatably connected to the inner wall of the water outlet pipe 5. A permanent magnet rotor 107 is rotatably connected to the outer wall of the water outlet pipe 5. A gear ring 108 is fixedly connected to the outer wall of the permanent magnet rotor 107. The gear 104 meshes with the gear ring 108.

[0053] like Figures 8-10 As shown, the cleaning assembly 20 includes a mounting rod 201 fixedly connected to the magnetic rotor 106. A third rotating shaft 202 is fixedly connected to one side of the mounting rod 201. Several connecting rods 203 are fixedly connected to the outer wall of the third rotating shaft 202. A scraper 204 is fixedly connected to one end of the connecting rod 203. The scraper 204 is in contact with the inner wall of the water outlet pipe 5. A rotating rod 205 is fixedly connected to the outer wall of the third rotating shaft 202. The rotating rod 205 is rotatably connected to the inner wall of the water outlet pipe 5.

[0054] like Figure 8 and Figure 10 As shown, the grinding assembly 30 includes a grinding block 301 fixedly connected to one end of the third rotating shaft 202, and a grinding seat 302 fixedly connected to the inner wall of the water outlet pipe 5.

[0055] When salt crystals form on the inner wall of the outlet pipe 5, the controller causes the second motor 102 to drive the second shaft 103 and gear 104 to rotate. Since gear 104 meshes with gear ring 108, gear ring 108 rotates synchronously with permanent magnet rotor 107. Simultaneously, through magnetic coupling, this drives the magnetic rotor 106, mounting rod 201, third shaft 202, connecting rod 203, scraper 204, and rotating rod 205 to rotate. This causes rotating rod 205 to rotate within the outlet pipe 5, facilitating timely scraping away of crystals on the inner wall of the outlet pipe 5 and preventing further crystal formation. The continuous accumulation of deposits causes the inner diameter of the pipe to shrink, ensuring smooth flow of wastewater within the pipe and reducing the risk of pipe blockage. At the same time, a non-contact drive is adopted, and the bottom of the outlet pipe 5 is kept completely sealed to avoid wastewater leakage. As the third rotating shaft 202 rotates, it drives the grinding block 301 to rotate. In conjunction with the grinding seat 302, it is convenient to grind the scraped crystals into fine particles, which can be easily carried into the subsequent treatment stages with the water flow. This avoids crystal accumulation and blockage of the pipe, while reducing wear on the pipe and subsequent equipment, and ensuring the stable operation of the entire wastewater treatment process.

[0056] To better explain the above embodiments, the present invention also proposes another implementation method: an environmentally friendly wastewater recycling process for dyeing equipment, comprising the following steps:

[0057] Step 1: Dyeing bamboo, wood, and rattan using a roller dyeing machine 1;

[0058] Step 2: Pretreatment component 2 extracts the high-salt and alkaline wastewater after dyeing and filters out large particulate suspended matter such as fibers;

[0059] Step 3: Neutralization component 3 neutralizes and coagulates / sediments the pretreated wastewater;

[0060] Step 4: Filter component 4 sequentially removes larger particulate impurities and suspended solids, organic matter, and some colloids and tiny particles from the wastewater;

[0061] Step 5: The reverse osmosis module 9 desalinates the high-salt wastewater, and the treated water is then recycled.
