Description

Technical Field

[0001] The utility model relates to the field of textile processing, in particular to a textile processing line and a water circulation system thereof. Background Art

[0002] Wastewater from the textile industry is characterized by large volumes, complex composition, and severe environmental pollution. Currently, domestic wastewater management efforts primarily focus on achieving discharge standards. Water scarcity, sustained economic growth, and population growth will inevitably lead to a relative shortage of water resources. For major water users like the textile industry, water recycling is essential not only for promoting the coordinated development of the economy, the environment, and society, but also for the sustainable development of the textile industry.

[0003] Existing textile processing lines use large amounts of water, such as in drying, cooling, and padding. Because different processes use varying amounts of water and temperatures, separate water recovery systems are often used for each process, increasing overall system usage. This is especially true for cooling water, which retains residual heat after cooling. Other water recovery systems are unable to utilize this heat, resulting in significant heat loss. Consequently, existing textile processing lines face difficulties in recovering and reusing water and its thermal energy. Utility Model Content

The water can flow through the water-using equipment used in each textile processing line in sequence through the liquid level difference between the layers, and finally be collected in the bottom-layer water collection tank at the bottom. The water can be recovered to the top-layer water storage mechanism through the bottom-layer reflux pump, thereby maximizing the utilization of water resources and heat energy.

[0045] like Figure 1-3 A water circulation system for a textile processing line comprises, from top to bottom, a top-layer water storage mechanism 1, a second-layer water supply mechanism 2 for a padder, a middle-layer water storage mechanism 3, and a bottom-layer water collection tank 4;

[0046] The sub-top padding water mechanism 2 includes: a sub-top water inlet pipe 21, a sub-top water outlet pipe 22, a uniform padding hydraulic station 23 and a cooling drying drum 24;

[0047] The water inlet end of the sub-top water inlet pipe 21 is connected to the water outlet end of the top water storage mechanism 1, and the water outlet end of the sub-top water inlet pipe 21 is connected to the water inlet end of the uniform rolling hydraulic station 23 or the water inlet end of the cooling drum 24; the water inlet end of the sub-top water outlet pipe 22 is connected to the water outlet end of the uniform rolling hydraulic station 23 or the water outlet end of the cooling drum 24;

[0048] The water outlet ends of some of the sub-top water outlet pipes 22 are connected to the water inlet ends of the middle water storage mechanism 3 or the bottom water collection box 4; the water outlet end of the middle water storage mechanism 3 is connected to one of the water inlet ends of the bottom water collection box 4;

[0049] One of the water outlet ends of the bottom water collection box 4 is connected to one of the water inlet ends of the top water storage mechanism 1 through a bottom return pipe 41 ; the bottom return pipe 41 is provided with a bottom return pump 42 .

[0050] The present invention provides a water circulation system for a textile processing line, which comprises, from top to bottom, a top-layer water storage mechanism 1, a sub-top-layer water-using mechanism for a rolling mill 2, a middle-layer water storage mechanism 3 and a bottom-layer water collection tank 4. The water can flow through the water-using equipment used by each textile processing line in sequence through the liquid level difference between the layers, and finally be collected in the bottom-layer water collection tank 4. The water can be recycled to the top-layer water storage mechanism 1 through the bottom-layer reflux pump 42, thereby maximizing the utilization of water resources and heat energy, solving the problem that the existing textile processing lines are difficult to recycle and reuse water and heat energy due to the complex structure.

[0051] Specifically, the top water storage mechanism 1 is located at the highest position and is used to store water in the system. When the lower layer needs water, its output end is opened to deliver water, such as when the sub-top padding water mechanism 2 and the middle water storage mechanism 3 need water. The water inlet end of the sub-top water inlet pipe 21 receives water from the top water storage mechanism 1 and then outputs it to the uniform padding hydraulic station 23 or the cooling and drying drum 24. The uniform padding hydraulic station 23 or the cooling and drying drum 24 are commonly used in textile processing. The uniform padding hydraulic station 23 is mainly used in the uniform padding. The uniform padding can compensate for the deflection of the rollers and obtain a uniform liquid carryover rate across the fabric width. Therefore, the uniform padding hydraulic station 23 is one of the main water-using devices in the textile processing line. The cooling and drying drum 24 is mainly used to fill the interior with cooling water or hot steam. The cooling and drying drum 24 contacts the fabric through its surface, drying or cooling the fabric. It is also one of the main water-using devices in the textile processing line. After passing through the uniform padder hydraulic station 23 or the cooling drum 24, the water is output to the sub-top water outlet pipe 22. The sub-top water outlet pipe 22 is directly connected to the water inlet of the middle water storage mechanism 3. Since the water used by the uniform padder hydraulic station 23 or the cooling drum 24 has relatively few impurities, it can be output to the middle water storage mechanism 3 for reuse. This water can be directly stored in the middle water storage mechanism 3 to supply water to the water-using equipment on the same floor. The middle water storage mechanism 3 is then connected to the bottom water collection tank 4 via a pipeline, and can output water to the bottom water collection tank 4, thereby collecting the water at the bottom of the bottom water collection tank 4. When the sub-top padder water supply mechanism 2, the middle water storage mechanism 3, and the bottom water collection tank 4 need water, the bottom return pipe 41 connects the bottom water collection tank 4 to the top water storage mechanism 1. Simply start the bottom return pump 42 to output the water from the bottom water collection tank 4 back to the top water storage mechanism 1, thus achieving water recycling for the textile processing line.

[0052] The uniform padder hydraulic station 23 is divided into a padding uniform padder hydraulic station 23 and a setting machine uniform padder hydraulic station 23 .

[0053] Optimally, the middle water storage mechanism 3 includes: a middle water storage tank 31 and a singeing treatment mechanism 32;

[0054] The singeing treatment mechanism 32 includes: a singeing water storage tank 321, a singeing cooling pipe 322, a singeing machine 323 and a singeing circulation pump 324;

[0055] The water outlet ends of some of the sub-top water outlet pipes 22 are connected to the water inlet ends of the middle water storage tank 31; the water outlet end of the middle water storage tank 31 is connected to one of the water inlet ends of the middle water storage tank 31;

[0056] The water outlet end of the middle water storage tank 31 is connected to the water inlet end of the singeing cooling pipe 322; the water outlet end of the singeing cooling pipe 322 is connected to the water inlet end of the singeing machine 323, and the water outlet end of the singeing machine 323 is connected to one of the water inlet ends of the middle water storage tank 31; the singeing circulation pump 324 is installed on the singeing cooling pipe 322.

[0057] The middle-layer water storage mechanism 3 can receive water from the sub-top layer water outlet pipe 22, and then output the water from the sub-top layer water outlet pipe 22 to the singeing water storage tank 321; the singeing water storage tank 321 can continuously output water to the water use point of the singeing machine 323 through the singeing cooling pipe 322; the singeing circulation pump 324 is arranged on the singeing cooling pipe 322, and the singeing circulation pump 324 can be started when needed to output the water in the singeing water storage tank 321 to the singeing machine 323 through the singeing cooling pipe 322, thereby providing cooling effect on the singeing machine 323 to take away the heat of the singeing machine 323, and then adjust the state during the singeing process; the water used up by the singeing machine 323 flows back to the singeing water storage tank 321 through the pipeline, thus forming a circulating loop.

[0058] Optimally, a singeing spreading roller 325 is provided inside the singeing machine 323, and a roller cooling channel is provided inside the singeing spreading roller 325. The water inlet end of the roller cooling channel is connected to the water outlet end of one of the singeing cooling pipes 322, and the water outlet end of the roller cooling channel is connected to the water inlet end of the singeing water tank 321 through a pipeline.

[0059] The interior of the singeing machine 323 is generally equipped with a singeing spread roller 325 for conveying cloth. The singeing spread roller 325 can guide the cloth to pass through the fire grate 326 of the singeing machine 323; the traditional singeing spread roller 325 is made of stainless steel. When the fire end of the fire grate 326 is facing the singeing spread roller 325, the singeing spread roller 325 will continue to heat the singeing spread roller 325. The singeing spread roller 325 is prone to bend in a long-term heating state, thereby affecting the normal conveying of the cloth; to this end, the present solution designs a hollow roller cooling channel inside the singeing spread roller 325 of the singeing machine 323. The roller cooling channel receives water from the singeing cooling pipe 322 and outputs the water to the singeing water storage tank 321, so that the heat is continuously discharged under the circulation of water, providing a cooling effect for the singeing spread roller 325, and avoiding local overheating and deformation of the singeing spread roller 325.

[0060] Optimally, a fire grate 326 is provided inside the singeing machine 323; an anti-bending cooling pipe is provided inside the fire grate 326, the water inlet end of the anti-bending cooling pipe is connected to the water outlet end of one of the singeing cooling pipes 322, and the water outlet end of the anti-bending cooling pipe is connected to the water inlet end of the singeing water tank 321 through a pipeline.

[0061] The fire end of the fire bar 326 in the singeing machine 323 faces the singeing distribution roller 325, and the fire bar 326 is the main fire area. Therefore, the temperature of the fire bar 326 is the highest, and it is easy to bend when it is under high temperature for a long time, thereby changing the fire position of the fire bar 326, and then causing the angle of the fire end of the fire bar 326 toward the singeing distribution roller 325 to change, affecting the normal fire direction, and causing the singeing to be unstable; for this reason, an anti-bending cooling pipe is provided in the fire bar 326, and the anti-bending cooling pipe receives the cooling water of the singeing cooling pipe 322. The heat of the anti-bending cooling pipe can be taken away by the circulating water, ensuring that the heat of the anti-bending cooling pipe is maintained within a specific temperature range, so as to increase the service life of the anti-bending cooling pipe and improve the singeing stability.

[0062] Optimally, the middle water storage tank 31 is located higher than the singeing water storage tank 321;

[0063] The middle water tank 31 is provided with a lower water outlet 311 near the bottom and an upper water outlet 312 near the top; the lower water outlet 311 is connected to the singeing water tank 321 through the singeing cooling pipe 322; the upper water outlet 312 is connected to the input end of the singeing water tank 321 and / or the input end of the bottom water collecting tank 4 through a pipeline.

[0064] The middle water storage tank 31 of this solution is used to receive water from the sub-top water supply mechanism 2 of the rolling mill. When the water consumption of the sub-top water supply mechanism 2 is large, the water storage capacity of the middle water storage tank 31 increases, and the middle water storage tank 31 may be filled up in a short time. In response to this, this solution designs an overflow structure on the structure of the middle water storage tank 31. Specifically, an upper water outlet 312 is set relatively above the middle water storage tank 31, and a lower water outlet 311 is set relatively below the middle water storage tank 31; the lower water outlet 311 is set relatively below the lower water outlet 311. The singeing cooling pipe 322 is connected to the singeing water tank 321, and this pipe can actively output water to the singeing water tank 321 as needed. The upper water outlet 312 is located relatively above the middle water tank 31, close to the top of the middle water tank 31. Therefore, when the water level in the middle water tank 31 reaches the upper water outlet 312, water can be passively output to the singeing water tank 321 and / or the bottom water collection tank 4, thereby avoiding the problem of water overload in the middle water tank 31. The lower water outlet 311 located below can adjust the valve body of the singeing cooling pipe 322 as needed to actively output water.

[0065] Optimally, the middle layer water storage mechanism 3 includes: a temperature detection device 313, a middle layer water storage inlet valve 314 and a middle layer water storage outlet valve 315;

[0066] The detection end of the temperature detection device 313 is located at the singeing water tank 321; the middle layer water storage inlet valve 314 is arranged on the singeing cooling pipe 322; the middle layer water storage outlet valve 315 is arranged at the water outlet end of the singeing water tank 321; the temperature detection device 313 is communicatively connected to the middle layer water storage inlet valve 314 and the middle layer water storage outlet valve 315.

[0067] The detection end of the temperature detection device 313 is set on the singeing water tank 321, which is used to detect the water temperature of the singeing water tank 321. The opening state of the middle water storage inlet valve 314 and the middle water storage outlet valve 315 can be adjusted according to the real-time temperature detected. For example, when the water temperature of the singeing water tank 321 is too high, the middle water storage outlet valve 315 is opened to discharge water to the bottom water collection tank 4, and the middle water storage inlet valve 314 is opened to input more water to neutralize the water temperature of the singeing water tank 321, thereby ensuring that the water temperature of the singeing water tank 321 remains within a specific temperature range. In addition, when the water temperature of the singeing water tank 321 is too low, the middle water storage inlet valve 314 and the middle water storage outlet valve 315 are kept in a closed state. When the water flows through the water end of the singeing machine 323, the water temperature of the singeing water tank 321 is increased, thereby ensuring that the water temperature of the singeing water tank 321 remains within a specific temperature range. In this way, the water temperature of the singeing water tank 321 is always kept at the optimal temperature.

[0068] Optimally, the cooling cylinder 24 is divided into at least one of: a pad dyeing cooling cylinder, a pre-shrinking cooling cylinder, a setting machine cooling cylinder, a mercerizing machine cooling cylinder, a scouring cooling cylinder, an oxygen bleaching cooling cylinder and a shrinking machine cooling cylinder.

[0069] The cooling drum 24 can be used according to the specific type of textile processing, such as pad dyeing, pre-shrinking, setting in a setting machine, mercerizing, scouring, oxygen bleaching, or shrinking in a shrinking machine. Thus, the cooling drum 24 can be used in all major processing steps of the entire textile processing line, and can receive cooling water from the sub-top water inlet pipe 21 when needed, achieving a full range of automatic water supply.

[0070] Optimally, there are multiple identical cooling cylinders 24 , and adjacent identical cooling cylinders 24 are connected in sequence, with some of the cooling cylinders 24 connected to the sub-top water inlet pipe 21 , and some of the cooling cylinders 24 connected to the sub-top water outlet pipe 22 .

[0071] In some textile processing steps, for the same type of cooling cylinders 24, the processing step may use more cooling cylinders 24, so multiple identical cooling cylinders 24 can be designed to be internally connected in sequence, for example, the internal water-using areas are connected in sequence through pipelines, so that the same processing step only requires fewer sub-top water inlet pipes 21 and sub-top water outlet pipes 22, thereby simplifying the structure of the sub-top padding water mechanism 2, thereby avoiding the problem of overly complex pipeline distribution.

[0072] Optimally, the top water storage mechanism 1 includes, from top to bottom, a top cooling tower 11, a top water storage tank 12 and a cooling room 13;

[0073] The water inlet of the top cooling tower 11 is connected to the water outlet of the bottom return pipe 41; the water outlet of the top cooling tower 11 is connected to the water inlet of the top water storage tank 12, and one of the water outlets of the top water storage tank 12 is connected to the water inlet of the sub-top water inlet pipe 21;

[0074] The cooling room 13 includes: a room 131, an air compressor 132, a cooling cycle water inlet pipe 133, a cooling cycle water outlet pipe 134 and a cooling cycle pump body 135;

[0075] The air compressor 132 is arranged in the compartment 131; the water inlet end of the cooling cycle water inlet pipe 133 is connected to one of the water outlet ends of the top water storage tank 12, the water outlet end of the cooling cycle water inlet pipe 133 is connected to the water inlet end of the air compressor 132, the water outlet end of the air compressor 132 is connected to the water inlet end of the cooling cycle water outlet pipe 134, and the water outlet end of the cooling cycle water outlet pipe 134 is connected to the water inlet end of the top cooling tower 11; the cooling cycle pump body 135 is arranged on the cooling cycle water inlet pipe 133 or the cooling cycle water outlet pipe 134.

[0076] The top-level water storage mechanism 1 can cool the water in the system by natural cooling; in the optimal embodiment, a top-level cooling tower 11 and a cooling room 13 can be provided; specifically, the top-level cooling tower 11 can receive water from the bottom-level return pipe 41. The top-level cooling tower 11 mainly utilizes the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the heat in the system and reduce the water temperature; thus, the top-level cooling tower 11 can output water through the cooling cycle water inlet pipe 133 to the air compressor 132. The air compressor 132 compresses the refrigerant into a high-temperature and high-pressure gas and sends it to the outdoor unit condenser. After cooling, it becomes a high-temperature and high-pressure liquid refrigerant. The liquid refrigerant is throttled and depressurized by the throttling component and becomes a low-temperature and low-pressure gas-liquid mixture (more liquid) through the cooling cycle water outlet pipe 134. It enters the top-level cooling tower 11 to absorb heat in the air and vaporize, and then returns to the air compressor 132 to continue compression, thereby realizing circulating refrigeration.

[0077] The cooling circulation pump body 135 can be installed in the cooling circulation water inlet pipe 133 or the cooling circulation water outlet pipe 134 according to the actual situation.

[0078] A textile processing line is provided with the water circulation system of the textile processing line mentioned above.

[0079] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
