A wastewater inlet pipe is provided at the center of the top of the quicksand filter box. Several groups of interlocking holes are distributed in a circular array around the edges of the top of the quicksand filter box. A step is coaxially arranged at the bottom of the interlocking hole, and the inner diameter of the step is smaller than the interlocking hole.

[0007] Furthermore, a group of sand filter mechanisms are movably installed in each group of the interlocking holes. The top of the sand filter mechanism is connected to the wastewater inlet pipe through a group of hoses, and the bottom extends into the quicksand filter box.

When the filter press moves to the bottom of the flocculation cylinder, all the wastewater is discharged, and most of the flocs are squeezed onto the inner wall of the bottom of the flocculation cylinder for unified collection. A small part is intercepted by the floc interception net. When the filter press rises, a small part of the intercepted flocs falls into the debris collection basin due to gravity. The double-layer interception of flocs not only makes the filtration work more thorough, but also realizes automatic collection and cleaning, avoids blockage, and ensures the smoothness of the channel.

[0016] 2. Since the pipeline for absorbing wastewater is a stepped square tube, the wastewater can enter the stepped square tube through each group of ultrafiltration oxide membranes in layers, and each group of ultrafiltration oxide membranes is respectively arranged on each group of stepped inclined planes, so that each group of ultrafiltration oxide membranes can be more evenly contacted with the wastewater. At the same time, the intercepted bacteria and microorganisms will not affect other groups of ultrafiltration oxide membranes due to sliding, which not only improves the oxidation filtration effect, but also ensures that the wastewater flows more evenly and that the groups of ultrafiltration oxide membranes will not affect each other.

[0017] 3. By setting the sand filter mechanism as a spherical structure, the contact area between the wastewater and the quicksand plate and the water outlet area can be increased in a limited space, thereby improving the efficiency of the quicksand filtration. At the same time, the interlocking plate and the interlocking hole, as well as the upper purification part and the lower purification part are all installed movably. When one or more groups of quicksand plates need to be cleaned, it is only necessary to take out the sand filter mechanism as a whole and separate the upper purification part from the lower purification part. The cleaning work can be completed without affecting the work of other groups of sand filter mechanisms, which improves work efficiency while ensuring the continuity of work.

[0018] 4. Several groups of water diversion straight channels and water diversion loops are set at the bottom of the filter press, so that a network can be formed at the bottom of the filter press to guide the flow of wastewater. When the filter press descends and contacts the wastewater, the wastewater will quickly pass through the network into each group of water suction buckets, thereby speeding up the flow of wastewater.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The embodiment of the present invention provides an environmentally friendly fiber product processing wastewater treatment and reuse device, for example, Figure 1 and Figure 2As shown, it includes a quicksand filter unit 100, the bottom edge of the main body of the quicksand filter unit 100 is connected to a first water outlet pipe 101, the other end of the first water outlet pipe 101 is connected to a flocculation cylinder 200, a flocculation water inlet hole 201 is provided at one edge of the bottom of the flocculation cylinder 200, and the flocculation cylinder 200 is connected to the first water outlet pipe 101 through the flocculation water inlet hole. The flocculation cylinder 200 is used to provide a container for the flocculation reaction of the wastewater. The quicksand filter unit 100 is used to filter large particles of impurities in the wastewater.

[0037] Exemplarily, a clean water pump 210 is provided on the top of the flocculation cylinder 200, and a clean water drain pipe 220 is connected to the output end of the clean water pump 210. A hydraulic cylinder 230 is provided on the inner wall of the top of the flocculation cylinder 200, and a plurality of groups of hydraulic springs 240 are arranged around the hydraulic cylinder 230.

[0038] Exemplarily, the bottom of the hydraulic cylinder 230 is connected to a filter press unit 300, and a sealing sleeve 301 is sleeved on the outer wall of the main body of the filter press unit 300, and the outer wall of the sealing sleeve 301 is slidably fitted with the inner wall of the flocculation cylinder 200. The filter press unit 300 is used to separate flocs from wastewater.

[0039] Specifically, the bottom of each group of hydraulic springs 240 is installed on the output end of the filter press unit 300 .

[0040] Exemplarily, a water collection unit 400 is connected above the filter press unit 300, and the output end of the water collection unit 400 is connected to the input end of the clean water pump 210. The water collection unit 400 is used to collect and filter the wastewater through an oxidation membrane.

[0041] For example, Figure 3 and Figure 4 As shown, the quicksand filter unit 100 includes a quicksand filter box 110, a wastewater inlet pipe 120 is provided at the top center of the quicksand filter box 110, a plurality of groups of interlocking holes 130 are distributed in a circular array around the edges of the top of the quicksand filter box 110, a step 140 is coaxially provided at the bottom of the interlocking hole 130, and the inner diameter of the step 140 is smaller than the interlocking hole 130.

[0042] Exemplarily, a group of sand filter mechanisms 150 are movably installed in each group of the interlocking holes 130 . The top of the sand filter mechanism 150 is connected to the wastewater inlet pipe 120 through a group of hoses, and the bottom extends into the quicksand filter box 110 .

[0043] For example, Figure 5 and Figure 6As shown, the sand filter mechanism 150 includes a sand filter inlet pipe 151, the top of which is connected to the wastewater inlet pipe 120, and a fitting plate 152 is sleeved on the outer wall of the sand filter inlet pipe 151, and the fitting plate 152 is movably installed in the fitting hole 130. The bottom of the sand filter inlet pipe 151 extends into the quicksand filter box 110 and is connected to a filter ball, which includes an upper purification part 153 and a lower purification part 154, both of which are hemispherical structures, which are movably installed with each other, and the two have the same structure.

[0044] Exemplarily, the upper purification part 153 includes an outer hemisphere 1531, an inner hemisphere 1532 is provided at the center of the cavity of the outer hemisphere 1531, and the space between the outer hemisphere 1531 and the inner hemisphere 1532 is a sand filter chamber, and a sand flow plate 1534 of the same hemispherical structure is provided in the sand filter chamber. The outer hemisphere 1531 and the inner hemisphere 1532 are evenly distributed with a plurality of groups of water filter holes 1533. A movable mounting ring 1535 is movably installed at the junction of the bottom openings of the outer hemisphere 1531 and the inner hemisphere 1532.

[0045] First, the wastewater is injected into each group of sand filter mechanisms 150 through the wastewater inlet pipe 120. When the wastewater enters the spherical cavity formed by the upper purification part 153 and the lower purification part 154, it will first enter the sand filter cavity through the water filter holes 1533 on the inner hemispheres 1532 of each group and contact with the quicksand plate 1534. Then, the granular impurities in the wastewater are intercepted by the crushed sand and gravel in the quicksand plate 1534, and the water flow will enter the quicksand filter box 110 through the gap.

[0046] By setting the sand filter mechanism 150 as a spherical structure, the contact area between the wastewater and the sand plate 1534 and the water outlet area can be increased in a limited space, thereby improving the efficiency of the sand filter. At the same time, the interlocking plate 152 and the interlocking hole 130, as well as the upper purification part 153 and the lower purification part 154 are all movably installed. When one or more groups of sand plates 1534 need to be cleaned, it is only necessary to take out the sand filter mechanism 150 as a whole and separate the upper purification part 153 and the lower purification part 154. The cleaning work can be completed without affecting the work of other groups of sand filter mechanisms 150, which improves the work efficiency and ensures the continuity of the work.

[0047] For example, Figure 7 and Figure 8 As shown, the filter press unit 300 includes a filter cartridge 310, and a plurality of groups of water diversion channels 311 are distributed in a circular array at the bottom of the filter cartridge 310, and a plurality of groups of water diversion channels 312 are arranged at equal intervals from its own central axis outward at the bottom of the filter cartridge 310, and each group of the water diversion channels 311 is connected to any group of the water diversion channels 312.

[0048] Exemplarily, a plurality of groups of material taking holes 320 are distributed in a circular array around the edges of the bottom of the filter cartridge 310, and each group of the material taking holes 320 is provided with a group of sealing doors 321. Each group of the material taking holes 320 is provided with a group of chip collecting basins 350, and an electric butterfly valve 340 is provided just above the chip collecting basin 350. A separation mechanism 330 is connected just above the electric butterfly valve 340, and the output end and input end of the separation mechanism 330 extend to the upper and lower sides of the filter cartridge 310 respectively. The input end of the separation mechanism 330 is connected to the corresponding groups of water diversion straight channels 311 and water diversion annular channels 312.

[0049] Specifically, a vent pipe is provided at the top of the filter press cartridge 310 , and the bottom of the vent pipe penetrates to the bottom of the filter press cartridge 310 , and a solenoid valve is provided on the vent pipe.

[0050] For example, Fig. 9 and Fig.10 As shown, the separation mechanism 330 includes a water suction bucket 331, the bottom diameter of the water suction bucket 331 is larger than the top, and the bottom of the water suction bucket 331 penetrates to the bottom of the filter cartridge 310, and is connected to the corresponding groups of water diversion straight channels 311 and water diversion ring channels 312. The top of the water suction bucket 331 is connected to a U-shaped tube 332, and the heights of the two ends of the U-shaped tube 332 are lower than the height in the middle. The other end of the U-shaped tube 332 is connected to a water outlet pipe 333 arranged in a vertical direction, the bottom of the water outlet pipe 333 is connected to an electric butterfly valve 340, and a flocculent net 334 is provided in the cavity. The top of the water outlet pipe 333 is connected to a second water pump.

[0051] After the wastewater is filtered through the quicksand, it enters the flocculation cylinder 200, and a flocculant is added to the wastewater in proportion. After the harmful substances in the wastewater are condensed into flocs, the hydraulic cylinder 230 is started, and the filter press cylinder 310 is driven down by the hydraulic cylinder 230, so that the wastewater enters the U-shaped tube 332 through the suction bucket 331, and then enters the outlet pipe 333, and then is sent to the water collection unit 400. At the same time, the second pump is turned on to speed up the flow of the wastewater. When the filter press cylinder 310 moves to the bottom of the flocculation cylinder 200, all the wastewater is discharged, and most of the flocs are squeezed onto the inner wall at the bottom of the flocculation cylinder 200 for unified collection. A small part of the flocs that enter the outlet pipe 333 are intercepted by the floc blocking net 334. When the filter press 310 rises, the solenoid valve is opened to discharge the external air into the space below the filter press 310 where the flocculation cylinder 200 is located, so as to facilitate the rise of the filter press 310. During the rising process, the second water pump is closed and the electric butterfly valve 340 is opened, so that a small part of the flocs intercepted by the floc intercepting net 334 falls into the debris collection basin 350 below under the action of gravity. By intercepting the flocs in two layers, not only the filtering work is made more thorough, but also automatic collection and cleaning are realized, ensuring the smoothness of the channel and avoiding the blockage of flocs caused by long-term work. Not only the wastewater is discharged more thoroughly, but also the interception effect of flocs is guaranteed, while ensuring the smoothness of the channel and avoiding blockage. While improving the purification effect, it also improves the convenience of later cleaning work.

[0052] A plurality of water diversion straight channels 311 and water diversion ring channels 312 are arranged at the bottom of the filter press 310, so that a network for guiding the flow of wastewater can be formed at the bottom of the filter press 310. When the filter press 310 descends and contacts the wastewater, the wastewater will quickly pass through the network and enter each group of water suction buckets 331, thereby accelerating the flow of the wastewater.

[0053] For example, Fig.11 and Fig.12 As shown, the water collection unit 400 includes a water collection cylinder 410, and a water cylinder clamp ring 420 is sleeved on the edges of the top of the water collection cylinder 410, and the water cylinder clamp ring 420 is installed on the inner wall of the top of the flocculation cylinder 200. A water collection outlet pipe 411 is provided on the top of the water collection cylinder 410, and the top of the water collection outlet pipe 411 is connected to the clean water pump 210. The bottom of the water collection outlet pipe 411 extends into the water collection cylinder 410 and is connected to an ultrafiltration outlet pipe 440. Several groups of ultrafiltration mechanisms 450 are distributed in a circular array around the bottom of the ultrafiltration outlet pipe 440.

[0054] Exemplarily, a number of groups of transverse tubes 430 equal to the number of separation mechanisms 330 are distributed in a circular array around the bottom of the water collecting cylinder 410, and the other end of the transverse tube 430 is connected to a bamboo hose 431, and the bottom of each group of bamboo hoses 431 is connected to a corresponding group of second water pumps.

[0055] For example, Fig.13 As shown, the ultrafiltration mechanism 450 includes a stepped square tube 451, which is a stepped structure, and a side wall of each step close to the central axis of the water collecting tube 410 is an inclined surface, and an ultrafiltration oxide membrane 452 is installed on the inclined surface.

[0056] After the wastewater after the flocculation reaction enters the water collecting cylinder 410 through each group of bamboo hoses 431 and the horizontal pipe 430, as the water level rises, it comes into contact with each group of ultrafiltration oxide membranes 452. Since the pipeline for absorbing wastewater is a stepped square tube 451, the wastewater can pass through each group of ultrafiltration oxide membranes 452 in layers and enter the stepped square tube 451. The bacterial microorganisms in the wastewater are filtered through the ultrafiltration oxide membrane 452, and then discharged through the ultrafiltration outlet pipe 440 and the water collecting outlet pipe 411, thereby obtaining the final purified water, so that the purified water can be recycled, achieving the purpose of wastewater treatment and reuse. Moreover, each group of ultrafiltration oxide membranes 452 is respectively arranged on each group of inclined planes arranged in a stepped manner, so that each group of ultrafiltration oxide membranes 452 can be more evenly contacted with the wastewater. At the same time, the intercepted bacterial microorganisms will not affect other groups of ultrafiltration oxide membranes 452 due to sliding. This not only improves the oxidation filtration effect, but also ensures that the wastewater flows more evenly and that the groups of ultrafiltration oxide membranes 452 will not affect each other.

[0057] The above embodiments have the following beneficial effects: 1. Control the filter press 310 to descend at a uniform speed so that the wastewater is squeezed out through the water suction bucket 311, the U-shaped tube 332 and the outlet pipe 333. When the filter press 310 moves to the bottom of the flocculation cylinder 200, all the wastewater is discharged, and most of the flocs are squeezed onto the inner wall at the bottom of the flocculation cylinder 200 for easy uniform collection. A small part is intercepted by the floc intercepting net 334. When the filter press 310 rises, a small part of the intercepted flocs falls into the debris basin 350 due to gravity. The double-layer interception of flocs not only makes the filtration work more thorough, but also realizes automatic collection and cleaning, avoids blockage, and ensures the smoothness of the channel. While improving the purification effect, it also improves the convenience of later cleaning work.

[0058] 2. Since the pipeline for absorbing wastewater is a stepped square tube 451, the wastewater can enter the stepped square tube 451 through each group of ultrafiltration oxide membranes 452 in layers, and each group of ultrafiltration oxide membranes 452 is respectively arranged on each group of stepped inclined surfaces, so that each group of ultrafiltration oxide membranes 452 can be more evenly contacted with the wastewater. At the same time, the intercepted bacteria and microorganisms will not affect other groups of ultrafiltration oxide membranes 452 due to sliding, which not only improves the oxidation filtration effect, but also ensures that the wastewater flows more evenly and that the groups of ultrafiltration oxide membranes 452 will not affect each other.

[0059] 3. By setting the sand filter mechanism 150 as a spherical structure, the contact area between the wastewater and the sand plate 1534 and the water outlet area can be increased in a limited space, thereby improving the efficiency of the sand filter. At the same time, the interlocking plate 152 and the interlocking hole 130, as well as the upper purification part 153 and the lower purification part 154 are all movably installed. When one or more groups of sand plates 1534 need to be cleaned, it is only necessary to take out the sand filter mechanism 150 as a whole and separate the upper purification part 153 and the lower purification part 154. The cleaning work can be completed without affecting the work of other groups of sand filter mechanisms 150, which improves the work efficiency and ensures the continuity of the work.

[0060] 4. A plurality of water diversion straight channels 311 and water diversion ring channels 312 are arranged at the bottom of the filter press 310, so that a network for guiding the flow of wastewater can be formed at the bottom of the filter press 310. When the filter press 310 descends and contacts the wastewater, the wastewater will quickly pass through the network and enter each group of water suction buckets 331, thereby accelerating the flow of wastewater.
