Abstract
Description
Technical Field
[0001] This invention relates to the field of textile production equipment technology, and in particular to a filtration device and wastewater treatment equipment for rinsing wastewater from textiles based on high-temperature airflow. Background Technology
[0002] Currently, textiles typically require specific bleaching agents during production to achieve the desired color and softness, thus better meeting market demands.
[0003] However, the rinsing process for textiles generates a large amount of wastewater. Direct discharge of this wastewater would severely pollute water resources, placing significant pressure on the environment. Therefore, many manufacturers now treat their wastewater before discharge to ensure it meets discharge standards, effectively preventing environmental pollution.
[0004] Because wastewater contains many flocculent substances, it needs to be pre-filtered to effectively remove these substances. Current methods for pre-filtration involve adding coagulants to cause the flocculants to coagulate and settle. However, this method requires precise control of the coagulant dosage; improper control can easily lead to secondary pollution, further increasing the wastewater's pollutant content and exacerbating environmental pollution. Furthermore, this method involves a long coagulation and sedimentation time and low treatment efficiency.
[0005] To avoid the aforementioned problems, a new method using high-pressure water flow to treat flocculent matter in wastewater has emerged on the market. For example, patent CN214271329U discloses a wastewater filtration device for yarn dyeing and spinning, comprising a housing with a top cover. A filter tank is located inside the housing, and a filter screen is fixed inside the filter tank near its lower part. An inlet is located on the side of the housing near the bottom of the filter screen. When the filter screen needs cleaning, backwash water is injected into the inlet pipe via a turbine and a spray pipe. When the backwash water enters the rotating pipe, the high-pressure water flow drives the turbine to rotate. The turbine is fixedly connected to the rotating pipe, allowing the high-pressure water flow to drive the rotating pipe to rotate. When the backwash water is sprayed out through the nozzles of the spray pipe, the spray pipe rotates, thoroughly rinsing the filter screen's pores. This facilitates backwashing of the filter screen, prevents yarn from clogging the filter screen's pores, and makes cleaning the filter screen easier.
[0006] Therefore, while the traditional high-pressure water jet treatment method can overcome the shortcomings of the coagulant-based method, it requires a large amount of water, resulting in water waste and placing significant pressure on water resources.
[0007] Therefore, it is of great significance to develop a water-saving and highly efficient treatment method. Summary of the Invention
[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a water-saving, highly efficient, and environmentally friendly wastewater filtration device and wastewater treatment equipment based on high-temperature airflow washing of textiles.
[0009] The objective of this invention is achieved through the following technical solution:

[0037] This application provides a wastewater filtration device for rinsing textiles based on high-temperature airflow, including a support and a filter tank. The filter tank is mounted on the support and has a communicating cavity, an inlet, a collection port, and an outlet. The wastewater filtration device also includes a heating component, an airflow component, and a collection component. The heating component is mounted on the outer peripheral wall of the filter tank and is used to heat the wastewater inside the filter tank. The airflow component is mounted inside the filter tank and is used to flush the wastewater inside the filter tank. The collection component includes a blower and a collection tank. The collection tank is connected to the collection port, and the blower is located adjacent to the collection port. The blower is used to extract flocculent matter from the wastewater so that the flocculent matter can be discharged from the collection port.
[0038] The aforementioned rinsing wastewater filtration device incorporates an airflow assembly within the filter tank. When this assembly connects to an external air supply assembly, gas flows out, flushing the wastewater within the filter tank. Simultaneously, a heating assembly on the outer wall of the filter tank, connected to an external power source, provides preliminary heating to the wastewater, reducing the moisture content of flocculent matter. A collection tank connected to a collection port, with an exhaust fan positioned near the port, draws flocculent matter from the filter tank into the collection tank for centralized treatment. The remaining liquid is discharged from the outlet, achieving preliminary filtration of textile wastewater. This method effectively avoids the use of large amounts of coagulant and water, conserving water resources while offering high treatment efficiency and environmental friendliness.
[0039] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments;
[0040] Please see Figures 1 to 3 A rinsing wastewater filtration device 10 according to one embodiment includes a support 100 and a filter tank 200. The filter tank 200 is disposed on the support 100. The filter tank 200 has a communicating cavity 210, an inlet 220, a collection port 230, and an outlet 240. The rinsing wastewater filtration device 10 also includes a heating component 300, an airflow component 400, and a collection component 500. The heating component 300 is disposed on the outer peripheral wall of the filter tank 200. The heating component 300 is used for... The filter tank 200 is used to heat the wastewater inside; the airflow assembly 400 is disposed inside the filter tank 200 and is used to flush the wastewater inside the filter tank 200; the collection assembly 500 includes a blower 510 and a collection tank 520, the collection tank 520 is connected to the collection port 230, the blower 510 is disposed adjacent to the collection port 230, and the blower 510 is used to extract flocculent matter from the wastewater so that the flocculent matter can be discharged from the collection port 230.
[0041] The aforementioned rinsing wastewater filtration device 10 includes an airflow assembly 400 installed inside the filter tank 200. When the airflow assembly 400 is connected to an external air supply assembly 600, gas can flow out from the airflow assembly 400 to flush the wastewater inside the filter tank 200. Simultaneously, in conjunction with the heating assembly 300 on the outer peripheral wall of the filter tank 200, when the heating assembly 300 is connected to an external power source, it can preliminarily heat the wastewater inside the filter tank 200 to reduce the moisture content of the flocculent matter in the wastewater. Since the collection tank 520 is connected to the collection port 230, and the exhaust fan 510 is installed near the collection port 230, when the exhaust fan 510 is working, it can draw the flocculent matter inside the filter tank 200 into the collection tank 520 to achieve centralized treatment of the flocculent matter in the wastewater. The liquid in the wastewater is discharged from the discharge port 240 to achieve preliminary filtration of textile wastewater. This effectively avoids the use of large amounts of coagulants and water flow, saving water resources and making the treatment more efficient and environmentally friendly.
[0042] like Figure 2 and Figure 3 As shown, in some embodiments, the airflow assembly 400 includes a main air pipe 410 and a plurality of first air inlets 420. The main air pipe 410 is disposed inside the filter canister 200 and has a plurality of air outlets 411. Each of the first air inlets 420 is disposed above the filter canister 200 and is connected to the main air pipe 410.
[0043] It is understandable that since multiple air outlets 411 are formed inside the main air pipe 410, the main air pipe 410, each first air inlet pipe 420 and multiple air outlets 411 are connected to the filter tank 200. When connected to the air supply assembly 600, the gas flows from the first air inlet pipe 420 into the main air pipe 410 and then flows out through the multiple air outlets 411 of the main air pipe 410. This ensures that the gas in the airflow assembly 400 can flush the wastewater in the filter tank 200, so that most of the flocculent matter in the wastewater can float on the liquid surface, thereby achieving better separation of flocculent matter from liquid.
[0044] like Figure 1 and Figure 3 As shown, in some embodiments, the airflow assembly 400 further includes a plurality of second air inlet pipes 430, each of the second air inlet pipes 430 being disposed below the filter canister 200, and each of the second air inlet pipes 430 being connected to the main air pipe 410.
[0045] It is understandable that by adding multiple second air inlet pipes 430 to the main air pipe 410 and connecting each second air inlet pipe 430 to the main air pipe 410, the gas flow rate of the main air pipe 410 can be further increased, and the wastewater in the filter tank 200 can be flushed more comprehensively, so as to achieve more comprehensive flushing of flocculent matter in the wastewater and more comprehensive removal of flocculent matter in the wastewater.
[0046] like Figure 7 As shown, in some embodiments, the air outlets 411 are staggered on the main air pipe 410. It can be understood that by staggering the multiple air outlets 411 on the main air pipe 410, multiple staggered airflows can be emitted from the main air pipe 410. This effectively avoids large airflows causing significant impact on the inner wall of the filter canister 200, thus preventing bending and deformation of the inner wall and improving the service life of the filter canister 200.
[0047] Furthermore, such as Figure 7As shown, in one embodiment, the vent 411 includes a first vent sub-vent 4111 and a second vent sub-vent 4112. The first vent sub-vent 4111 and the second vent sub-vent 4112 are respectively inclinedly disposed on the main air pipe 410, and both the first vent sub-vent 4111 and the second vent sub-vent 4112 are inclined in the direction of the flow of the flocculent material. It can be understood that since the first vent sub-vent 4111 and the second vent sub-vent 4112 are respectively inclinedly disposed on the main air pipe 410, the gas coming out of the first vent sub-vent 4111 and the second vent sub-vent 4112 can more easily lift the flocculent material for better flushing. At the same time, it also helps the main air pipe 410 generate an airflow that moves towards the collection port 230, so as to collect the flocculent material into the collection tank 520 more quickly, thereby improving the wastewater treatment efficiency.
[0048] Furthermore, such as Figure 3 As shown, in some embodiments, the first air inlet pipes 420 and the second air inlet pipes 430 are staggered. It can be understood that by staggering the first air inlet pipes 420 and the second air inlet pipes 430, the gas entering through the first air inlet pipes 420 and the second air inlet pipes 430 is prevented from canceling each other out, resulting in a smaller airflow from the main air pipe 410 and insufficient flushing of wastewater. Therefore, by staggering the first air inlet pipes 420 and the second air inlet pipes 430, the gas entering through the first air inlet pipes 420 and the gas entering through the second air inlet pipes 430 are ensured to have better air pressure, thereby ensuring more comprehensive flushing of wastewater.
[0049] like Figure 1 As shown, in some embodiments, the airflow assembly 400 further includes an air supply assembly 600, which is connected to the airflow assembly 400 and is used to supply airflow to the airflow assembly 400 to ensure that the air supply assembly 600 can provide better air pressure to the airflow assembly 400, thereby ensuring that the airflow assembly 400 can flush the wastewater.
[0050] In some embodiments, the air supply assembly 600 includes a plurality of first blowers and a plurality of second blowers. Each first blower is connected to a first air inlet pipe 420, and each second blower is connected to a second air inlet pipe 430. This ensures that each first blower can provide good airflow to each first air inlet pipe 420, and each second blower can provide good airflow to each second air inlet pipe 430. This ensures that the air supply assembly 600 can provide good air pressure to the airflow assembly 400, thereby ensuring a more comprehensive flushing of the wastewater.
[0051] like Figure 2 and Figure 3As shown, in some embodiments, the filter tank 200 includes a heating zone 250 and a non-heating zone 260. The heating component 300 is disposed on the outer peripheral wall of the heating zone 250, and the non-heating zone 260 is connected to the collection port 230. It can be understood that by adding a non-heating zone 260 between the collection port 230 and the heating zone 250, the exhaust fan 510 can effectively extract the flocculent material, thus preventing the exhaust fan 510 from drawing excessive gas and liquid into the collection tank 520, thereby improving the recovery rate of liquid in the wastewater.
[0052] In some embodiments, when the heating component 300 heats the filter tank 200, the heating temperature is controlled to be between 90°C and 180°C. By controlling the temperature of the heating component 300 to be between 90°C and 180°C, it is ensured that the heating component 300 can effectively remove moisture from the flocculent material. Further, in a preferred embodiment, the heating temperature is between 120°C and 160°C.
[0053] like Figure 2 As shown, in some embodiments, the filter tank 200 is horizontally inclined on the support 100. It can be understood that by horizontally inclinedly arranging the filter tank 200 on the support 100, the filter tank 200 and the support 100 maintain a slope, thus ensuring that wastewater can flow relatively quickly to the discharge pipe. Simultaneously, in conjunction with the use of the airflow assembly 400, the wastewater treatment efficiency can be improved.
[0054] like Figure 3As shown, in some embodiments, the filter tank 200 is arranged to gradually slope downwards from away from the collection tank 520 toward the collection tank 520. It is understandable that, since the filter tank 200 is inclined downwards from the collection tank 520, the distance between the heating zone 250 of the filter tank 200 and the surface of the wastewater is shorter than the distance between the non-heating zone 260 and the surface of the wastewater. This allows the wastewater to be quickly flushed by a high-temperature airflow in the heating zone 250 from one end of the inlet 220, achieving a more comprehensive flushing of the wastewater and thus achieving better separation of flocs from the liquid. At this point, a large amount of flocs has already been separated from the wastewater. Most of the flocs floating above the filter tank 200 are towards the collection port 230 and close to the upper side wall of the filter tank 200. If the heating component 300 is used to continue heating the upper side wall of the filter tank 200, the temperature may become too high, causing the flocs to adhere to the side wall of the filter tank 200, thereby reducing the recovery rate of the flocs. Therefore, this application adds a non-heating zone 260 to prevent flocculent material from adhering to the side wall of the filter tank 200, thereby improving the recovery rate of flocculent material. At the same time, since the distance between the non-heating zone 260 and the liquid surface of the wastewater is relatively long, that is, the distance between the flocculent material and the liquid is relatively long, the exhaust fan 510 can extract the flocculent material more comprehensively while reducing the extraction of liquid, thus achieving a high recovery rate for both flocculent material and liquid.
[0055] In some embodiments, the inclination angle between the filter tank 200 and the support 100 is 0° to 35°. It is understood that if the inclination angle between the filter tank 200 and the support 100 is greater than 35°, the slope of the filter tank 200 and the support 100 will be larger, causing the wastewater in the filter tank 200 to flow more rapidly towards the discharge pipe. This prevents the airflow assembly 400 from thoroughly flushing the wastewater, thus reducing the efficiency of treating flocculent matter in the wastewater. Therefore, by controlling the inclination angle of the filter tank 200 to 0° to 35°, this application ensures that the wastewater in the filter tank 200 has a suitable flow. Simultaneously, in conjunction with the use of the airflow assembly 400, it ensures that the airflow assembly 400 thoroughly flushes the wastewater, thereby improving the efficiency of treating flocculent matter in the wastewater more comprehensively.
[0056] like Figure 4 As shown, in one embodiment, the first air intake pipe 420 is provided with a first swinging and tapping pipe 421 protruding from it. The first swinging and tapping pipe 421 forms a plurality of first vent holes 4211, and each of the first vent holes 4211 is connected to the first air intake pipe 420.
[0057] It is understandable that by providing a first swinging tapping tube 421 protruding from the first air inlet pipe 420, gas can enter from the first air inlet pipe 420 and flow to the first swinging tapping tube 421, thereby causing the first swinging tapping tube 421 to swing between the filter tank 200 and the liquid surface. In other words, when the first swinging tapping tube 421 swings between the filter tank 200 and the liquid surface, it can accelerate the airflow above the filter tank 200 to accelerate the movement of the flocculent material floating above the filter tank 200 towards the collection port 230, thereby increasing the collection speed of the flocculent material. On the other hand, it can also play a certain tapping role on the liquid surface, that is, it can create waves on the liquid surface, thereby playing a certain flushing role on the wastewater, thereby improving the flushing efficiency of the wastewater and further improving the wastewater treatment efficiency.
[0058] It should be noted that when the first swaying tapping tube 421 swings above the filter tank 200, flocculent material can easily adhere to or become entangled on it. Therefore, this application forms multiple first vent holes 4211 in the first swaying tapping tube 421, allowing the gas from these holes to backwash any material adhering to or entangled on the tube. This effectively prevents flocculent material from easily adhering to or becoming entangled on the tube. Simultaneously, the gas from the multiple vent holes 4211 can also effectively push the flocculent material towards the collection port 230, thereby accelerating the collection efficiency.
[0059] In one embodiment, the first swishing and tapping tube 421 has a closed end, and the first vent 4211 is disposed on the outer wall of the first swishing and tapping tube 421 adjacent to the liquid surface.
[0060] It is understandable that, since the first swinging and tapping tube 421 has a closed end, the gas pressure coming out of the first vent 4211 of the first swinging and tapping tube 421 is relatively large, thus generating a better swinging force on the first swinging and tapping tube 421. Since the first vent 4211 is located on the outer wall of the first swinging and tapping tube 421 near the liquid surface, the gas in the first vent 4211 can push the first swinging and tapping tube 421 upward. When the first swinging and tapping tube 421 is blocked by the side wall of the filter tank 200 during its movement, it can move closer to the liquid surface and tap the liquid surface. When the first swinging and tapping tube 421 is blocked by the liquid surface, it will move closer to the side wall of the filter tank 200. In this way, the first swinging and tapping tube 421 can swing and tap the liquid surface above the filter tank 200. In addition, the first slapping tube 421 is blocked by the side wall of the filter can 200, which can slap and vibrate the side wall of the filter can 200, thereby cleaning the flocculent matter and dirt adhering to the side wall of the filter can 200 and effectively reducing the difficulty of subsequent cleaning of the filter can.
[0061] like Figure 4 As shown, in one embodiment, the first slapping tube 421 is further provided with a second vent 4212. The second vent 4212 is disposed on the outer side wall of the first slapping tube 421 away from the liquid surface. The second vent 4212 is used to backflush the flocculent material adhering to the side wall of the first slapping tube 421.
[0062] It is understood that by adding a second vent 4212 to the outer wall of the first swishing and tapping tube 421 away from the liquid surface, the second vent 4212 can backflush the flocculent material adhering to the side wall of the first swishing and tapping tube 421, thereby effectively reducing the amount of flocculent material adhering to or entangled on the first swishing and tapping tube 421, thus improving the collection of flocculent material in wastewater and increasing the service life of the first swishing and tapping tube 421.
[0063] like Figure 4 As shown, in one embodiment, the first vent 4211 and the second vent 4212 are respectively inclinedly disposed on the first swinging and beating tube 421, and the inclination direction of the first vent 4211 and the second vent 4212 is the same as the flow direction of the collected flocculent material.
[0064] It is understood that by tilting the first vent 4211 and the second vent 4212 onto the first swinging tapping tube 421, and by setting the tilting direction of the first vent 4211 and the second vent 4212 the same as the flow direction of the collected flocs, the gas coming out of the first vent 4211 and the second vent 4212 can better push the flocs towards the collection port 230, thereby improving the collection of flocs in the wastewater. Furthermore, the first vent 4211 gradually slopes downwards from near the collection port 230 to away from the collection port 230, while the second vent 4212 gradually slopes upwards from away from the collection port 230 to near the collection port 230. This ensures that the gas exiting the first and second vents 4212 can effectively propel the flocculent material above the filter tank 200, thereby improving the flocculent material recovery rate. Simultaneously, the airflow from the first and second vents 4211 can effectively wash away the flocculent material adhering to the outer wall of the first oscillating tapping tube 421, preventing excessive flocculent material from adhering to the side wall of the filter tank 200 and making the filter tank 200 difficult to clean. Furthermore, the second vent 4212 is smaller than the first vent 4211 to ensure that the first oscillating tapping tube 421 can oscillate. Furthermore, the inclination angle between the first vent 4211 and the first swinging tapping tube 421 is 10°~55°, and the inclination angle between the second vent 4212 and the first swinging tapping tube 421 is 10°~55°.
[0065] In one embodiment, one end of the first oscillating tapping tube 421 is connected to the first air inlet pipe 420, and the first oscillating tapping tube 421 is made of a heat-resistant elastic material. It can be understood that because one end of the first oscillating tapping tube 421 is connected to the first air inlet pipe 420, the other end of the first oscillating tapping tube 421 is a free end, and the first oscillating tapping tube 421 is made of a heat-resistant elastic material to ensure that the first oscillating tapping tube 421 can oscillate within the filter canister 200. Further, the closed end of the first oscillating tapping tube 421 is disposed on the free end to ensure that the first oscillating tapping tube 421 can oscillate within the filter canister 200. Further, the heat-resistant elastic material can be any one of high-temperature resistant silicone, styrene-based thermoplastic elastomers, or olefin-based thermoplastic elastomers. In a preferred embodiment, the heat-resistant elastic material is high-temperature resistant silicone.
[0066] In some embodiments, the first blower is a variable-speed blower. It is understood that due to the uneven airflow distribution of the variable-speed blower, the airflow into the first inlet pipe 420 is uneven, resulting in fluctuations in the airflow of the first oscillating beater pipe 421. This ensures more effective flushing of wastewater and also ensures that the first oscillating beater pipe 421 can oscillate. That is, when the airflow entering the first oscillating beater pipe 421 is small, the first oscillating beater pipe 421 can move closer to the liquid surface under the influence of gravity; when the airflow entering the first oscillating beater pipe 421 is large, the first oscillating beater pipe 421 will move away from the liquid surface, so that the first oscillating beater pipe 421 can oscillate within the filter tank 200.
[0067] Furthermore, in a preferred embodiment, the air pressure of the first blower is 70kPa~150kPa to ensure that the first blower can provide a good airflow to the first air inlet pipe 420, so as to ensure that the first swinging tapping pipe 421 can swing well above the filter tank 200 under this airflow condition.
[0068] like Figure 3 and Figure 6 As shown, in some embodiments, the second air inlet pipe 430 is provided with a second swinging and tapping pipe 431, which is inclinedly disposed on the second air inlet pipe 430 and has a plurality of third vent holes 4311. It can be understood that by adding a second swinging and tapping pipe 431, the airflow from the plurality of third vent holes 4311 of the second swinging and tapping pipe 431 can form an "airflow tree," thereby better flushing the flocculent matter inside the wastewater, improving the filtration and separation of the flocculent matter, and thus increasing the recovery rate of the flocculent matter.
[0069] In some embodiments, the opening of the third vent 4311 faces upwards towards the filter tank 200 to ensure the formation of an upward "airflow tree" within the wastewater, thereby better achieving comprehensive flushing of the flocculent matter inside the wastewater. Furthermore, the port of the third vent 4311 is flush with the sidewall of the second agitator tube 431. This ensures the formation of an upward "airflow tree" within the wastewater while effectively preventing excessive flocculent matter from entangled or adhering to the outlet end of the third vent 4311, thus achieving better comprehensive flushing of the flocculent matter inside the wastewater. Furthermore, the second agitator tube 431 is made of a heat-resistant elastic material. Furthermore, the heat-resistant elastic material can be high-temperature resistant silicone.
[0070] Furthermore, such as Figure 6 As shown, in one embodiment, there are multiple third vent holes 4311, which are staggered and disposed on the outer peripheral wall of the second swinging and beating tube 431 to ensure that the second swinging and beating tube 431 can form an airflow tree in the wastewater.
[0071] Furthermore, such as Figure 6 As shown, in one embodiment, there are multiple second agitator tubes 431, which are staggered and arranged on the second air inlet pipe 430. It can be understood that by adding multiple second agitator tubes 431, a larger airflow tree can be formed in the wastewater, thereby improving the airflow pressure on the wastewater and more quickly flushing the flocculent matter in the wastewater to the liquid surface, thus improving the wastewater treatment efficiency.
[0072] Furthermore, such as Figure 4 and Figure 6 As shown, the first air inlet pipe 420 has a first vent hole 422 at one end extending into the filter tank 200, and the second air inlet pipe 430 has a second vent hole 432 at one end extending into the filter tank 200. This can further improve the flushing of wastewater by the airflow assembly 400, not only improving the recovery rate of flocculent matter but also improving the wastewater treatment efficiency.
[0073] In some embodiments, the second blower is a variable speed blower. It can be understood that due to the uneven airflow distribution of the variable speed blower, the airflow flowing into the second air inlet pipe 430 is uneven, resulting in a fluctuation difference in the airflow entering the second swinging tapping pipe 431, so as to ensure that the second swinging tapping pipe 431 can swing in the wastewater.
[0074] In some embodiments, the air pressure of the second blower is 80kPa~180kPa to ensure that the second blower can provide a good airflow to the second air inlet pipe 430, so that the second swinging tapping pipe 431 can generate a "flow tree" in the wastewater and swing under this airflow condition.
[0075] In some embodiments, the first blower operates intermittently when flushing wastewater. This intermittent aeration ensures that the flushed flocs remain floating on the surface for a longer period, allowing the heating element 300 to better remove moisture from them. This enables the exhaust fan 510 to more quickly draw the flocs into the collection tank 520, improving wastewater treatment efficiency. Furthermore, intermittent aeration ensures better oscillation of the first swinging pipe 421, facilitating more effective flushing of the wastewater and further enhancing treatment efficiency. Additionally, intermittent aeration prevents the second swinging pipe 431 from adhering or entangled due to prolonged oscillation, extending its lifespan and improving floc recovery rates.
[0076] Similarly, in some embodiments, the second blower operates intermittently when flushing wastewater. It is understood that by setting the second blower to operate intermittently, on the one hand, the intermittent airflow ensures that the second swinging beater tube 431 can swing more effectively, thus ensuring that the second swinging beater tube 431 can better flush the wastewater with airflow, thereby further improving wastewater treatment efficiency; on the other hand, the intermittent airflow also avoids the phenomenon of excessive flocculent adhesion or entanglement caused by prolonged swinging of the second swinging beater tube 431. This not only increases the service life of the second swinging beater tube 431 but also improves the recovery rate of flocculents.
[0077] Furthermore, in a preferred embodiment, the intermittent nature refers to intermittent air supply, i.e., the first blower or the second blower operates for 10 to 40 minutes, then pauses for 2 to 10 minutes. In practical applications, the intermittent nature is 15 minutes of operation followed by a 3-minute pause. This ensures that the first and second agitating pipes 421 and 431 can oscillate effectively within the filter tank to accelerate wastewater treatment efficiency. It also prevents excessive flocculent material from adhering to or entangled in the first and second agitating pipes 421 and 431, thereby improving the flocculent material recovery rate.
[0078] like Figure 3As shown, in some embodiments, the rinsing wastewater filtration device 10 further includes a transfer device, the filter tank 200 has an outlet 270, the transfer device is connected to the discharge port 240, the transfer device is disposed adjacent to the discharge port 240, and the transfer device is used to collect the gas from the discharge port 240.
[0079] It is understandable that, since a heating element 300 is installed on the outer peripheral wall of the filter tank 200, and the wastewater contains rinsing agents, when the heating element 300 heats the filter tank 200, volatile gases will be generated. If these gases are not discharged in time, the high gas pressure inside the filter tank 200 could easily lead to a safety accident. Therefore, this application forms an outlet 270 in the filter tank 200 and installs a transfer device at the outlet 270. This transfer device can collect the gas in the filter tank 200, ensuring a relatively stable gas pressure inside the filter tank 200 and preventing a safety accident caused by high gas pressure. At the same time, the transfer device can also collect volatile gases in a timely manner, effectively preventing the direct emission of volatile gases into the air, which is more environmentally friendly.
[0080] like Figure 5 As shown, in some embodiments, a filter screen 271 is provided inside the air outlet 270. It can be understood that by providing a filter screen 271 inside the air outlet 270, flocculent matter can be effectively prevented from entering the transfer equipment from the air outlet 270, thereby ensuring that the transfer equipment can collect more gas.
[0081] Furthermore, such as Figure 5 As shown, in some embodiments, a first backflushing pipe 272 is also provided inside the air outlet 270. The first backflushing pipe 272 is used for backflushing and cleaning the filter screen 271. It can be understood that by adding a first backflushing pipe 272 inside the air outlet 270, when the first backflushing pipe 272 is connected to an external air pipe, the gas in the first backflushing pipe 272 can backflush the filter screen 271, thereby effectively flushing away the flocculent material adhering to the filter screen 271, so that the flocculent material adhering to the filter screen 271 can be flushed back into the filter tank 200. In this way, on the one hand, it can avoid the blockage of the air outlet pipe and prevent safety accidents, thereby ensuring that the gas can smoothly enter the transfer equipment, and on the other hand, it can improve the treatment efficiency of flocculent material in wastewater.
[0082] Furthermore, in some embodiments, the first backflushing pipe 272 is disposed on the side of the filter screen 271 facing away from the filter tank 200. It is understood that as flocculent matter flows with the gas from inside the filter tank 200 to the outlet 270, the side of the filter screen 271 facing the filter tank 200 is prone to flocculent matter adhesion, which can easily lead to clogging of the filter screen 271 over long-term use. Therefore, in order to more comprehensively and effectively remove the flocculent matter adhering to the filter screen 271, the first backflushing pipe 272 is disposed on the side of the filter screen 271 facing the filter tank 200. This ensures that the backflushing gas can more comprehensively remove the flocculent matter adhering to the filter screen 271, ensures a larger airflow at the outlet 270, improves the gas recovery of the transfer equipment, better ensures the stability of the air pressure inside the filter tank 200, and thus improves the safety of the filtration device for textile washing wastewater based on high-temperature airflow.
[0083] In some embodiments, the filter screen 271 is backwashed 1 to 3 times every 0.5 to 1 hour using the first backwash pipe 272 to ensure that the filter screen 271 remains unobstructed throughout the use of the textile washing wastewater filtration device based on high-temperature airflow. This can improve the recovery rate of gas and flocculent matter and enhance production safety.
[0084] like Figure 3 and Figure 4 As shown, in some embodiments, the textile rinsing wastewater filtration device based on high-temperature airflow further includes multiple second backwash pipes 280. Each second backwash pipe 280 is disposed above the filter tank 200, and the second backwash pipes 280 are sequentially distributed along the length of the filter tank 200. This allows the multiple second backwash pipes 280 to backwash and flush the inner wall of the filter tank 200, preventing flocculent matter from adhering to the inner wall of the filter tank 200, thereby improving the efficiency of flocculent matter treatment and reducing the difficulty of cleaning the filter tank 200.
[0085] like Figure 4 As shown, in some embodiments, the outlet end of the second backflushing pipe 280 is flush with the inner wall of the filter tank 200. It can be understood that by setting the outlet end of the second backflushing pipe 280 to be flush with the inner wall of the filter tank 200, the adhesion or entanglement of flocculent material on the protruding second backflushing pipe 280 can be avoided, thereby improving the recovery rate of flocculent material.
[0086] Furthermore, such as Figure 4 and Figure 5As shown, in some embodiments, the outlet ends of the first backflushing pipe 272 and the second backflushing pipe 280 are formed with double-ball funnel nozzles 2721. This ensures a large backflushing airflow to better flush the adhered flocculent material. On the other hand, since the double-ball funnel nozzle 2721 has a certain buffer section, when the first backflushing pipe and the second backflushing pipe are performing backflushing operations, the flocculent material enters the double-ball funnel nozzle 2721, which has a certain buffer section, effectively preventing the flocculent material from leaking out. At the same time, when the first backflushing pipe 272 and the second backflushing pipe 280 perform backflushing again, a small amount of flocculent material in the buffer section can be flushed back into the filter tank 200, thereby improving the recovery rate of flocculent material.
[0087] This application also provides a textile wastewater treatment device, including the high-temperature airflow-based textile rinsing wastewater filtration device described in any of the above embodiments. It is understood that applying the high-temperature airflow-based textile rinsing wastewater filtration device of this application to textile wastewater treatment equipment can effectively save a significant amount of water.
[0088] Compared with the prior art, the present invention has at least the following advantages:
[0089] The aforementioned rinsing wastewater filtration device 10 includes an airflow assembly 400 installed inside the filter tank 200. When the airflow assembly 400 is connected to an external air supply assembly 600, gas can flow out from the airflow assembly 400 to flush the wastewater inside the filter tank 200. Simultaneously, in conjunction with the heating assembly 300 on the outer peripheral wall of the filter tank 200, when the heating assembly 300 is connected to an external power source, it can preliminarily heat the wastewater inside the filter tank 200 to reduce the moisture content of the flocculent matter in the wastewater. Since the collection tank 520 is connected to the collection port 230, and the exhaust fan 510 is installed near the collection port 230, when the exhaust fan 510 is working, it can draw the flocculent matter inside the filter tank 200 into the collection tank 520 to achieve centralized treatment of the flocculent matter in the wastewater. The liquid in the wastewater is discharged from the discharge port 240 to achieve preliminary filtration of textile wastewater. This effectively avoids the use of large amounts of coagulants and water flow, saving water resources and making the treatment more efficient and environmentally friendly.
[0090] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
