Description

Technical Field

[0001] The invention relates to the technical field of wastewater degradation, and in particular to a process for degrading aqueous leather wastewater and a wastewater degradation device. Background Art

[0002] Water-based leather wastewater mainly comes from the production and processing of water-based leather (also called water-based environmentally friendly leather or water-based synthetic leather). Water-based leather is a leather substitute that uses water-based materials such as water-based polyurethane as the main film-forming substance. It simulates the appearance and feel of traditional leather, but has a more environmentally friendly production process. In the process of producing water-based leather, a large amount of water is required for cleaning, soaking, spraying and other process steps. At the same time, various chemical reagents and additives are added to promote the formation of leather and give it specific properties. These mixtures of water and chemicals form water-based leather wastewater before discharge.

[0003] In the prior art, a Chinese patent with announcement number CN221701162U discloses a leather wastewater treatment device to treat leather wastewater. The technical solution disclosed in the patent document is as follows: it includes a debris removal box and a purification box, and the inner walls on both sides of the debris removal box are provided with second slide grooves, and the second slide grooves are used for sliding installation of the second slider. The second slider is relatively provided at two locations, and a top cover is buckled at the top of the purification box, and a motor is fixedly installed at the center of the top of the top cover. The output end of the motor passes through the top cover and is fixedly connected to the top of the rotating rod. The second sliders at the two locations are hingedly connected to the precision filter screen through hinges, and a first slide groove is provided at the top of the second slider, and the first slider is movably installed inside the first slide groove. The precision filter installed by the hinge can salvage and remove the leather fiber and other impurities in the impurity removal box, and can be salvaged repeatedly to completely remove the leather fiber impurities in the wastewater. And through the hollow design of the rotating rod, the purifier can be put into the mesh tube at the bottom of the rotating rod to react with the wastewater, thereby avoiding the collision of the purifier with the stirring rod. However, since the leather wastewater contains organic matter, it needs to be degraded. If it is not degraded and discharged into the environment, it will seriously pollute the water body, affect the water quality, and even cause harm to aquatic organisms, destroying the ecological balance. At present, in the process of degrading organic matter by biodegradation, it is necessary to control the pH value in the biochemical pool. When the pH value is low, it will cause sludge swelling and inhibit the activity and growth of microorganisms. In the process of pH adjustment in the biochemical pool, the pH conversion rate in the sludge is slow, which causes the microorganisms in the sludge to be in an inhibitory environment for a long time, slowing down the degradation of organic matter. Summary of the invention

[0004] The purpose of the present invention is to provide a process and a wastewater degradation device based on aqueous leather wastewater to solve the problem that the pH conversion rate of sludge in the biochemical pool in the above-mentioned background technology is slow, which inhibits the activity and growth of microorganisms and slows down the degradation rate of organic matter.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A wastewater degradation device comprises: a track device for guiding the device to perform linear motion along a biological pool, a power assembly for driving the device to move along the track device, a lifting assembly for driving the transmission assembly to lift and lower is fixedly installed on the power assembly, a working assembly is fixedly installed on the bottom of the transmission assembly, the working assembly is used to cut the sludge at the bottom of the biological pool to increase the contact area between the sludge and the water in the biological pool, an air supply assembly for inflating the working assembly is fixedly installed on one side of the transmission assembly, and the sludge cut by the working assembly can be blown to further increase the contact area between the sludge and the water in the biological pool; the power assembly comprises a cross frame, a power device is symmetrically fixedly installed on the top of the cross frame, guide wheels for driving the device to move are fixedly installed at the four corners of the bottom end of the cross frame, the power device and the guide wheels are matched and connected, a support frame is symmetrically fixedly installed on the top of the cross frame, a mounting plate is provided on the top of the two support frames, and the bottom ends of the mounting plate are respectively fixedly connected to the tops of the two support frames.

[0007] By adopting the above technical scheme, when the pH value of the biochemical pool is adjusted, in order to quickly convert the pH value of the sludge at the bottom of the biochemical pool to an appropriate value, the power component on the device will drive the device to move linearly along the track device. At the beginning of the linear movement, the lifting component will drive the rod transmission component, the working component and the gas transmission component to descend. As the three continue to descend to the bottom of the biochemical pool, the transmission component will drive the working component to rotate, so that the working component rotates from a vertical state to a horizontal state, so that the working component can better shovel up the sludge at the bottom of the pool, thereby increasing the contact area between the sludge at the bottom of the pool and the pool water, and further accelerating the pH value in the sludge. The conversion rate of the H value can adjust the living environment of the microorganisms in the sludge, which helps the microorganisms maintain a high activity, thereby more effectively degrading the organic pollutants in the sewage. In addition, the gas supply component can continuously supply gas to the cutting end of the working component when the working component cuts the sludge, so that when the working component scoops up the sludge, it can impact the sludge through gas supply, and impact some grooves on the surface of the strip-shaped sludge, further increasing the contact area between the sludge and the pool water. Moreover, the continuous gas supply of the gas supply component can make the sludge contact with oxygen, so that aerobic microorganisms can get oxygen supply, maintain a high activity, and further degrade the wastewater.

[0008] A further improvement of the technical solution of the present invention is that the lifting assembly includes a lifting motor fixedly installed on the top of the mounting plate, the output end of the lifting motor passes through the side wall of the mounting plate and is fixedly installed with a transmission wheel, the interior of the mounting plate is rotatably connected with a synchronous pulley structure, the transmission wheel and the synchronous pulley structure are transmission-coordinatedly connected, the bottom two ends of the mounting plate are rotatably connected with a screw rod, the bottom two ends of the cross frame are respectively fixedly installed with auxiliary frames, the ends of the two screw rods away from the mounting plate are respectively rotatably connected with the auxiliary frames, sliding rods are symmetrically fixedly installed between the mounting plate and the auxiliary frame, the lifting plate is threadedly connected to the screw rod, and the two ends of the lifting plate are respectively slidably connected with the sliding rods.

[0009] By adopting the above technical solution, when the working component needs to be driven to perform lifting work, the lifting motor drives the synchronous pulley structure to rotate through the transmission wheel, and the synchronous pulley structure synchronously drives the screw rods at both ends to rotate. As the screw rod rotates, the screw rod drives the lifting plate to lift. In order to ensure that the lifting plate driven by the screw rod maintains stable lifting work, sliding rods for limiting the lifting plate are provided on both sides of the screw rod. As the lifting plate is lifted and lowered, the transmission assembly and the working assembly installed at its bottom will be lifted and lowered synchronously, so that the working assembly can smoothly descend to a suitable working position, thereby realizing the working assembly to process the sludge.

[0010] A further improvement of the technical solution of the present invention is that the transmission assembly includes connecting columns equidistantly fixed on the lower surface of the lifting plate, the bottom ends of the connecting columns are fixedly connected to the upper surface of the mounting frame, the top center of the mounting frame is fixedly installed with a mounting shell, the order tube of the mounting frame is fixedly installed with a working motor, the internal rotation of the mounting frame is connected with a transmission rod, the output ends of the two working motors are fixedly connected to one end of the transmission gear set, the other ends of the two transmission gear sets are respectively fixedly connected to the two transmission rods, one end of the two transmission rods are fixedly installed with a worm, the internal ends of the mounting frame are rotatably connected with a worm wheel, the worm and the worm wheel are meshedly connected, the two ends of the mounting frame are internally connected with a connecting rod, and the two connecting rods are respectively fixedly connected with the two worm wheels, the bottom end of the mounting frame is symmetrically connected with a bevel gear set, one end of the two bevel gear sets is respectively fixedly connected to one end of the two connecting rods, the bottom end of the mounting frame is symmetrically connected with a connecting seat, and one end of the two connecting seats extends to the interior of the mounting frame and is respectively fixedly connected to the other end of the two bevel gear sets.

[0011] By adopting the above technical solution, the two working motors will drive the transmission rod to rotate through the transmission gear set. As the transmission rod rotates, the transmission rod will synchronously drive the worm to rotate, and the worm wheel meshing with it will follow the rotation. The worm wheel drives the connecting rod to rotate, and the connecting rod drives the bevel gear set to realize the rotation of the connecting seat. As the two connecting seats rotate synchronously, the working assembly at the bottom of the connecting seat will rotate synchronously, thereby causing the working assembly to rotate from a vertical state to a horizontal state, so that the sludge in the biochemical pool can be shoveled up by the working assembly, thereby increasing the contact area between the sludge and the pool water in the biochemical pool, and further increasing the conversion rate of the pH value in the sludge.

[0012] A further improvement of the technical solution of the present invention is that the working component includes a bucket fixedly connected to two connecting seats, a plurality of first dividing strips are fixedly installed at one end of the bucket at equal distances, a plurality of second dividing plates are provided at the top of the first dividing strips, and the second dividing plates are fixedly connected to the bucket, and three layered plates are fixedly installed at one end of the bucket away from the first dividing strips.

[0013] By adopting the above technical solution, after the lifting assembly moves the transmission assembly and the working assembly to the appropriate position, the transmission assembly will synchronously drive the working assembly to rotate. As the working assembly is in a horizontal state, the power assembly driving device moves along the track device. As the device moves, the bucket will shovel up the sludge at the bottom of the pool. In order to increase the shoveling effect of the bucket on the sludge, the bucket is fixedly equipped with a first dividing strip and a second dividing plate in a double layer, which can cut the lumped sludge into strips, increase the contact area between the sludge and the pool water, and increase the pH conversion rate of the sludge. In addition, the three buckets installed at one end of the bucket can cut the shoveled sludge again to further increase the contact area between the sludge and the pool water, so as to better provide the device with the sludge processing work.

[0014] A further improvement of the technical solution of the present invention is that a cutting block for cutting sludge is arranged at the end of the layered plate arranged in the middle.

[0015] By adopting the above technical solution, the cutting block fixedly installed at the end of the middle layered plate can cooperate with the first dividing strip and the second dividing plate to cut the scooped sludge, so that the block sludge can be turned into strips, thereby increasing the contact area between the sludge and the pool water as much as possible and quickly completing the pH conversion of the sludge.

[0016] A further improvement of the technical solution of the present invention is that the gas transmission component includes a connecting plate fixedly installed on one side of the connecting column, connecting pipes are symmetrically fixedly installed on one side of the connecting plate, one end of the two connecting pipes passes through the lifting plate, and the other end of the two connecting pipes is fixedly installed with an air intake pipe, one side of the middle layered plate is fixedly connected to the air intake pipe through a mounting seat, one side of the three layered plates are provided with a ventilation bin, the end of the ventilation bin is provided with a branch guide strip, and the branch guide strip is fixedly connected to the layered plate, and an air outlet is formed between the branch guide strip and the layered plate.

[0017] By adopting the above technical scheme, after the sludge at the bottom of the pool is scooped up by the bucket, and then cut into layers by the first dividing strip, the second dividing plate and the stratification plate, the connecting pipe sends the external air into the ventilation bin inside the stratification plate through the air inlet pipe and the mounting seat, and then sprays the sludge from the air outlet arranged on the surface of the stratification plate to impact the surface of the sludge, so that grooves are formed on the surface of the sludge, further increasing the contact area between the sludge and the surface of the pool water, and in addition, the oxygen in the air can be transported to the bottom of the pool to avoid the lack of oxygen inside the sludge and thus form an anaerobic environment, which can increase the activity and growth of microorganisms in the sludge and increase the degradation efficiency of organic matter.

[0018] A further improvement of the technical solution of the present invention is that the first partition strips, the second partition plates and the air outlets are all arranged in a staggered manner.

[0019] By adopting the above technical solution, the staggered arrangement of the first dividing strip, the second dividing plate and the air outlet can prevent the upper and lower sides of the strip-shaped sludge from being impacted by the air blown out of the air outlet at the same time, avoid breaking up the sludge, avoid the phenomenon of requiring a long time to settle, and further increase the convenience of the device when in use.

[0020] A further improvement of the technical solution of the present invention is that the ends of the three layered plates are connected to each other, and the ventilation compartments of the three layered plates form a connected air cavity.

[0021] By adopting the above technical solution, the interconnecting air cavity formed by the three stratified plates can facilitate the connecting pipe to transport the external air to the stratified plates, and then better discharge the air from the air outlet on the stratified plates, thereby supplying oxygen and blowing the sludge, increasing the activity and growth of microorganisms in the sludge, and better degrading the wastewater.

[0022] The present invention also provides a process for degrading aqueous leather wastewater, comprising the following steps:

[0023] S1, device debugging stage, when the device enters the water pool, the device is first tested to simulate the entire process of the device entering the water pool;

[0024] S2. Adjust the pH value of the wastewater in the pool, adjust the environment of the entire wastewater, and then place the working end of the device against the pool wall and lower it to the bottom of the pool. When the working end of the device contacts the sludge at the bottom of the pool, the working end of the device deforms and shovels the sludge at the edge of the bottom of the pool. During the shoveling process, the device as a whole operates slowly until the working end of the device is horizontal. The device as a whole operates normally again to process the sludge at the bottom of the pool. The sludge is cut by the device to increase the contact area between the sludge and the pool water, and complete the release and degradation of organic matter in the sludge.

[0025] S3. Sludge environment adjustment. In order to ensure the survival of microorganisms in the bottom sludge, air can be selectively introduced or reagents can be adjusted to a good level during the process of the device treating the bottom sludge, thereby adjusting the living environment of the microorganisms in the sludge.

[0026] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0027] 1. The present invention realizes rapid pH conversion of the sludge at the bottom of the biochemical pool through the coordinated mechanism of the transmission component and the working component. The transmission component drives the deformation of the working component, so that the working component reduces the working dead angle when shoveling the sludge at the bottom of the biochemical pool, expands the working range, and is more convenient for the device to process the sludge at the bottom of the pool. In addition, after the sludge is shoveled by the working component, the contact area between the sludge and the pool water can be increased, and the conversion rate of the pH value of the sludge can be further improved, so that the living environment of the microorganisms in the sludge can be adjusted, which helps the microorganisms maintain a high activity, thereby more effectively degrading organic pollutants in sewage.

[0028] 2. The present invention can quickly separate the sludge into strips by using the first dividing strip and the second dividing plate provided in the working component, which can increase the contact area between the treated sludge and the pool water, thereby increasing the pH conversion rate of the sludge. In order to increase the contact area between the sludge surface and the pool water after the separation treatment, the device is provided with an air supply component for cooperating with the working component to treat the sludge surface after the separation, and continuously blows air to the upper and lower surfaces of the sludge strips to increase the fluidity of the pool water on the sludge surface and better provide the sludge for pH conversion. The air supply component can also layer the shoveled sludge, and the uninterrupted air supply of the air supply component can transport air to the surface of the sludge strip to avoid the formation of an anaerobic environment inside it, which can increase the activity and growth of microorganisms in the sludge.

[0029] 3. The present invention can facilitate secondary treatment of the upper and lower surfaces of the sludge after strip processing by staggered arrangement of the first dividing strip, the second dividing plate and the air outlet, so that grooves are formed on the surface of the sludge strip, further increasing the contact area between the sludge strip and the pool water, thereby increasing the pH conversion rate of the sludge, and adjusting the living environment of the microorganisms in the sludge, so that the microorganisms maintain a high activity.

[0030] 4. The present invention forms a stable power transmission device through a track device in conjunction with a power component, which can enable the device to maintain stable and slow movement when processing sludge, and then cooperate with the transmission component and the working component to process the sludge at the bottom of the pool, increase the pH value adjustment between it and the pool water, and improve the living environment of microorganisms inside the sludge, thereby allowing the microorganisms to maintain a high activity and effectively degrade sewage.

[0031] 5. The present invention can change the working posture of the working component while working through the rotation of the transmission component, so that the working component rotates when it contacts the sludge. At the same time, the device as a whole moves forward slowly, and combined with the rotation of the working component, the sludge on the edge of the pool bottom can be shoveled up, thereby increasing the working range of the device, and the sludge on the bottom of the biochemical pool can be treated more thoroughly to avoid the impact of untreated sludge on the biochemical pool.

DETAILED DESCRIPTION

[0046] The present invention is further described in detail below in conjunction with embodiments:

[0047] Example 1

[0048] As shown in the figure, Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the present invention provides a wastewater degradation device, including: a track device 1, used to guide the device to perform linear motion along the biological pool, a power assembly 2 is provided on the track device 1 for driving the device to move along the track device 1, a lifting assembly 3 for driving a transmission assembly 4 to perform lifting is fixedly installed on the power assembly 2, a working assembly 5 is fixedly installed at the bottom of the transmission assembly 4, the working assembly 5 is used to cut the sludge at the bottom of the biological pool to increase the contact area between the sludge and the water in the biological pool, and a lifting assembly 3 for driving a transmission assembly 4 to perform lifting is fixedly installed on the power assembly 2. The air supply component 6 for inflation can blow air into the sludge cut by the working component 5, further increasing the contact area between the sludge and the water in the biological pool; the power component 2 includes a cross frame 7, a power device 8 is symmetrically fixedly installed on the top of the cross frame 7, and guide wheels 9 that are moved by the driving device are fixedly installed at the four corners of the bottom end of the cross frame 7. The power device 8 and the guide wheel 9 are matched and connected, and a support frame 10 is symmetrically fixedly installed on the top of the cross frame 7. The tops of the two support frames 10 are provided with mounting plates 11, and the bottom ends of the mounting plates 11 are respectively fixedly connected to the tops of the two support frames 10.

[0049] In this embodiment, when the pH value of the biochemical pool is adjusted, in order to quickly convert the pH value of the sludge at the bottom of the biochemical pool to an appropriate value, the power component 2 on the device will drive the device to move linearly along the track device 1. At the beginning of the linear movement, the lifting component 3 will drive the rod transmission component 4, the working component 5 and the gas transmission component 6 to descend. As the three continue to descend to the bottom of the biochemical pool, the transmission component 4 will drive the working component 5 to rotate, so that the working component 5 rotates from a vertical state to a horizontal state, so that the working component 5 can better shovel up the sludge at the bottom of the pool, thereby increasing the contact area between the sludge at the bottom of the pool and the pool water, and further accelerating the sludge. The conversion rate of pH value in the sludge can adjust the living environment of microorganisms in the sludge, which helps the microorganisms maintain a high activity, thereby more effectively degrading organic pollutants in the sewage. In addition, the gas supply component 6 can continuously supply gas to the cutting end of the working component 5 when the working component 5 cuts the sludge, so that when the working component 5 scoops up the sludge, the sludge is impacted by gas supply, and some grooves are impacted on the surface of the strip-shaped sludge, further increasing the contact area between the sludge and the pool water. In addition, the continuous gas supply of the gas supply component 6 can make the sludge contact with oxygen, so that aerobic microorganisms can get oxygen supply, maintain a high activity, and further degrade the wastewater.

[0050] Example 2

[0051] The sludge in the biochemical pool is always at the bottom of the pool under the water surface, so when the sludge needs to be treated, the treatment device needs to be extended to the bottom of the pool. Therefore, a lifting component 3 is provided on the device for driving the working component 5 to lift and lower, so that the working component 5 can be moved to the bottom of the pool to treat the sludge.

[0052] like Figure 6 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the lifting component 3 includes a lifting motor 12 fixedly mounted on the top of the mounting plate 11, the output end of the lifting motor 12 is fixedly mounted with a transmission wheel 13 through the side wall of the mounting plate 11, the interior of the mounting plate 11 is rotatably connected with a synchronous pulley structure 14, the transmission wheel 13 and the synchronous pulley structure 14 are transmission-coordinatedly connected, the bottom ends of the mounting plate 11 are rotatably connected with a screw rod 15, the bottom ends of the cross frame 7 are respectively fixedly mounted with auxiliary frames 16, the ends of the two screw rods 15 away from the mounting plate 11 are respectively rotatably connected with the auxiliary frames 16, sliding rods 17 are symmetrically fixedly mounted between the mounting plate 11 and the auxiliary frame 16, a lifting plate 18 is threadedly connected to the screw rod 15, and the two ends of the lifting plate 18 are respectively slidably connected with the sliding rod 17.

[0053] In this embodiment, when it is necessary to drive the working component 5 to perform lifting work, the lifting motor 12 drives the synchronous pulley structure 14 to rotate through the transmission wheel 13, and the synchronous pulley structure 14 synchronously drives the screw rods 15 at both ends to rotate. As the screw rod 15 rotates, the screw rod 15 will drive the lifting plate 18 to lift. In order to ensure that the screw rod 15 drives the lifting plate 18 to maintain stable lifting work, sliding rods 17 for limiting the lifting plate 18 are provided on both sides of the screw rod 15. As the lifting plate 18 is lifted and lowered, the transmission component 4 and the working component 5 installed at its bottom will be lifted and lowered synchronously, so that the working component 5 can smoothly descend to a suitable working position, thereby realizing the working component 5 to process the sludge.

[0054] Example 3

[0055] In order to avoid working blind spots when the working component 5 is in use, the working component 5 is always in a vertical state before working, so that the working component 5 cannot shovel the sludge in the biochemical pool in the above state. Therefore, after the working component 5 comes into contact with the sludge, the working component 5 needs to be deformed by the transmission component 4, so that the working component 5 is in a horizontal state, and the power component 2 drives the device to move along the track device 1, so as to process the sludge at the bottom of the entire biochemical pool.

[0056] like Figure 7 , Figure 8 and Fig. 9As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the transmission assembly 4 includes connecting columns 19 equidistantly fixedly installed on the lower surface of the lifting plate 18, the bottom ends of the plurality of connecting columns 19 are fixedly connected to the upper surface of the mounting frame 20, a mounting shell 21 is fixedly installed at the top center of the mounting frame 20, a working motor 22 is fixedly installed on the order tube of the mounting frame 20, a transmission rod 24 is rotatably connected inside the mounting frame 20, the output ends of the two working motors 22 are fixedly connected to one end of a transmission gear set 23, the other ends of the two transmission gear sets 23 are respectively fixedly connected to the two transmission rods 24, and the two transmission rods 24 are fixedly connected to each other. 4 is fixedly installed with a worm 25, and both ends of the interior of the mounting frame 20 are rotatably connected with worm wheels 26, and the worm 25 and the worm wheel 26 are meshed and connected. Connecting rods 27 are rotatably connected to the interior of the mounting frame 20 at both ends, and the two connecting rods 27 are respectively fixedly connected to the two worm wheels 26. The bottom end of the mounting frame 20 is symmetrically rotatably connected with a bevel gear set 28, and one end of the two bevel gear sets 28 is respectively fixedly connected to one end of the two connecting rods 27. The bottom end of the mounting frame 20 is symmetrically rotatably connected with a connecting seat 29, and one end of the two connecting seats 29 extends to the interior of the mounting frame 20 and is respectively fixedly connected to the other end of the two bevel gear sets 28.

[0057] In this embodiment, at this time, the two working motors 22 will drive the transmission rod 24 to rotate through the transmission gear set 23. As the transmission rod 24 rotates, the transmission rod 24 will synchronously drive the worm 25 to rotate, and the worm wheel 26 meshing with it will follow the rotation, and the connecting rod 27 is driven by the worm wheel 26 to rotate, and the connecting rod 27 drives the bevel gear set 28 to realize the rotation of the connecting seat 29. As the two connecting seats 29 rotate synchronously, the working component 5 at the bottom of the connecting seat 29 will rotate synchronously, thereby causing the working component 5 to rotate from a vertical state to a horizontal state, so that the sludge in the biochemical pool can be shoveled up by the working component 5, thereby increasing the contact area between the sludge and the water in the biochemical pool, and further increasing the conversion rate of the pH value in the sludge.

[0058] When the pH value in the biochemical pool needs to be adjusted, since the sludge is at the bottom of the biochemical pool, the contact area between the sludge and the pool water is smaller, which makes the pH value conversion rate inside the sludge slower. The low pH value will inhibit microorganisms and cause the death of microorganisms, thereby reducing the sewage treatment efficiency and causing harmful substances in the sludge to enter the water, thereby affecting the water quality. Therefore, in order to solve the above-mentioned problems, a working component 5 is provided in the device to shovel the sludge at the bottom of the pool to increase the contact area between the sludge and the pool water, thereby accelerating the pH exchange rate.

[0059] like Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, in the present embodiment, preferably, the working assembly 5 includes a bucket 30 fixedly connected between two connecting seats 29, a plurality of first dividing bars 31 are fixedly installed at one end of the bucket 30 at equal distances, a plurality of second dividing plates 32 are provided at the top end of the first dividing bars 31, and the second dividing plates 32 are fixedly connected to the bucket 30, and three layering plates 33 are fixedly installed at one end of the bucket 30 away from the first dividing bars 31.

[0060] In this embodiment, after the lifting assembly 3 moves the transmission assembly 4 and the working assembly 5 to the appropriate position, the transmission assembly 4 will synchronously drive the working assembly 5 to rotate. As the working assembly 5 is in a horizontal state, the power assembly 2 drives the device to move along the track device 1. As the device moves, the bucket 30 will shovel up the sludge at the bottom of the pool. In order to increase the shoveling effect of the bucket 30 on the sludge, the bucket 30 is fixedly installed with a first dividing strip 31 and a second dividing plate 32 in a double layer, which can cut the lumped sludge into strips, increase the contact area between the sludge and the pool water, and increase the pH conversion rate of the sludge. In addition, the three buckets 30 installed at one end of the bucket 30 can cut the shoveled sludge again to further increase the contact area between the sludge and the pool water, so as to better provide the device for shoveling the sludge.

[0061] Since the end of the layering plate 33 arranged in the middle is arranged in a plane, when the layering plate 33 cuts the sludge, its contact area is large and the shoveled sludge cannot be broken quickly. Therefore, the above problem needs to be solved.

[0062] like Fig.11 As shown, preferably, the end of the intermediate layering plate 33 is provided with a cutting block for cutting the sludge.

[0063] In this embodiment, the dividing block fixedly installed at the end of the middle layering plate 33 can cooperate with the first dividing strip 31 and the second dividing plate 32 to divide the scooped sludge, so that the block sludge can be transformed into a strip shape, thereby increasing the contact area between the sludge and the pool water as much as possible and quickly completing the pH conversion of the sludge.

[0064] Example 4

[0065] When the working component 5 cuts the sludge, it can only increase the contact area between the sludge and the pool water, and achieve a rapid conversion of the pH value inside the sludge. However, this type of cutting cannot supply oxygen to the inside of the sludge, which will form an anaerobic environment inside the sludge, inhibiting the growth and activity of aerobic microorganisms and reducing the degradation efficiency of organic matter. Therefore, the device is provided with a gas supply component 6 for supplying oxygen to the cut sludge.

[0066] like Fig.12As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the gas delivery component 6 includes a connecting plate 37 fixedly installed on one side of the connecting column 19, and connecting pipes 38 are symmetrically fixedly installed on one side of the connecting plate 37, one end of the two connecting pipes 38 passes through the lifting plate 18, and the other end of the two connecting pipes 38 is fixedly installed with an air intake pipe 39, and one side of the middle layered plate 33 is fixedly connected to the air intake pipe 39 through a mounting seat 40, and a ventilation bin 34 is opened on one side of the three layered plates 33, and a branch guide strip 36 is provided at the end of the ventilation bin 34, and the branch guide strip 36 is fixedly connected to the layered plate 33, and an air outlet 35 is formed between the branch guide strip 36 and the layered plate 33.

[0067] In this embodiment, after the sludge at the bottom of the pool is scooped up by the bucket 30, and then cut into layers by the first dividing strip 31, the second dividing plate 32 and the layering plate 33, the connecting pipe 38 delivers external air into the ventilation bin 34 inside the layering plate 33 through the air inlet pipe 39 and the mounting seat 40, and then sprays the sludge from the air outlet 35 set on the surface of the layering plate 33 to impact the surface of the sludge, so that grooves are formed on the surface of the sludge, further increasing the contact area between the sludge and the pool water surface, and in addition, the oxygen in the air can be transported to the bottom of the pool to avoid the lack of oxygen in the sludge and thus form an anaerobic environment, which can increase the activity and growth of microorganisms in the sludge and increase the degradation efficiency of organic matter.

[0068] like Fig.10 As shown, preferably, the first partition strips 31 , the second partition plates 32 and the air outlets 35 are all arranged in a staggered manner.

[0069] In this embodiment, the staggered arrangement of the first dividing strip 31, the second dividing plate 32 and the air outlet 35 can prevent the upper and lower sides of the strip-shaped sludge from being impacted by the air blown out of the air outlet 35 at the same time, avoid breaking up the sludge, avoid the phenomenon of requiring a long time to settle, and further increase the convenience of the device when in use.

[0070] like Fig.12 As shown, preferably, the ends of the three layered plates 33 are connected to each other, and the ventilation chambers 34 of the three layered plates 33 form a connected air cavity.

[0071] In this embodiment, the interconnecting air cavity formed by the three stratification plates 33 can facilitate the connecting pipe 38 to transport external air to the stratification plate 33, and then better discharge the air from the air outlet 35 on the stratification plate 33, thereby supplying oxygen and blowing the sludge, increasing the activity and growth of microorganisms in the sludge, and better degrading the wastewater.

[0072] The present invention also provides a process for degrading aqueous leather wastewater, comprising the following steps:

[0073] S1, device debugging stage, when the device enters the water pool, the device is first tested to simulate the entire process of the device entering the water pool;

[0074] S2. Adjust the pH value of the wastewater in the pool, adjust the environment of the entire wastewater, and then place the working end of the device against the pool wall and lower it to the bottom of the pool. When the working end of the device contacts the sludge at the bottom of the pool, the working end of the device deforms and shovels the sludge at the edge of the bottom of the pool. During the shoveling process, the device as a whole operates slowly until the working end of the device is horizontal. The device as a whole operates normally again to process the sludge at the bottom of the pool. The sludge is cut by the device to increase the contact area between the sludge and the pool water, and complete the release and degradation of organic matter in the sludge.

[0075] S3. Sludge environment adjustment. In order to ensure the survival of microorganisms in the bottom sludge, air can be selectively introduced or reagents can be adjusted to a good level during the process of the device treating the bottom sludge, thereby adjusting the living environment of the microorganisms in the sludge.

[0076] The working principle of the aqueous leather wastewater degradation process and wastewater degradation device is described in detail below.

[0077] like Figure 1-Figure 12 As shown, when the pH value of the biochemical pool is adjusted, in order to quickly convert the pH value of the sludge at the bottom of the biochemical pool to an appropriate value, the power component 2 on the device will drive the device to perform linear motion along the track device 1. At the beginning of the linear motion, the lifting component 3 will drive the rod transmission component 4, the working component 5 and the gas transmission component 6 to descend, and the lifting motor 12 drives the synchronous pulley structure 14 to rotate through the transmission wheel 13, and the synchronous pulley structure 14 synchronously drives the screw rods 15 at both ends to rotate. As the screw rod 15 rotates, the screw rod 15 will drive the lifting plate 18 to lift, and in order to ensure that the screw rod 15 drives the lifting plate 18 to maintain a stable lifting operation, sliding rods 17 for limiting the lifting plate 18 are provided on both sides of the screw rod 15. As the lifting plate 18 rises and falls, the transmission component 4 and the working component 5 installed at the bottom thereof will rise and fall synchronously, so that the working component 5 can smoothly descend to a suitable working position, thereby realizing the processing of the sludge by the working component 5;

[0078] As the three continue to descend to the bottom of the biochemical pool, at this time, the transmission component 4 will drive the working component 5 to rotate, so that the working component 5 rotates from a vertical state to a horizontal state, and the two working motors 22 will drive the transmission rod 24 to rotate through the transmission gear set 23. As the transmission rod 24 rotates, the transmission rod 24 will synchronously drive the worm 25 to rotate, and the worm gear 26 meshing with it will follow the rotation, and the connecting rod 27 is driven by the worm gear 26 to rotate, and the connecting rod 27 drives the bevel gear set 28 to realize the rotation of the connecting seat 29. As the two connecting seats 29 rotate synchronously, the working component 5 at the bottom of the connecting seat 29 will rotate synchronously, so that the working component 5 can rotate from a vertical state to a horizontal state, so that the sludge in the biochemical pool can be shoveled by the working component 5, thereby increasing the contact area between the sludge and the water in the biochemical pool, and further increasing the conversion rate of the pH value in the sludge;

[0079] In addition, the air supply component 6 can continuously supply air to the cutting end of the working component 5 when the working component 5 is cutting the sludge. After the sludge on the bottom of the pool is scooped up by the bucket 30, and then cut into layers by the first dividing strip 31, the second dividing plate 32 and the layering plate 33, the connecting pipe 38 delivers external air into the ventilation bin 34 inside the layering plate 33 through the air inlet pipe 39 and the mounting seat 40, and then sprays the sludge from the air outlet 35 set on the surface of the layering plate 33 to impact the surface of the sludge, so that grooves are formed on the surface of the sludge, further increasing the contact area between the sludge and the surface of the pool water. In addition, the oxygen in the air can be transported to the bottom of the pool to avoid the lack of oxygen in the sludge and thus form an anaerobic environment, which can increase the activity and growth of microorganisms in the sludge and increase the degradation efficiency of organic matter.

[0080] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
