Abstract
Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for the production of polyurethane rubber vulcanizing agents. Background Technology
[0002] The wastewater generated during the production of polyurethane rubber vulcanizing agents is characterized by high COD concentration and high ammonia nitrogen content. The advantage of the MBBR process lies in its ammonia nitrogen removal rate of over 95%. This is mainly achieved by adding packing material with a density close to but less than water to the wastewater. Under aeration or stirring, the packing material is fully fluidized, forming a biofilm on the packing material. Thus, each packing material acts as a micro-reactor. The structure of the packing material is as follows... Figure 1 As shown;
[0003] In this invention, wastewater treatment equipment and its process flow mainly refer to wastewater treatment equipment and treatment mechanisms that apply MBBR technology.
[0004] In MBBR packed tanks, mechanical stirring fluidization mechanism is gradually being replaced by aeration fluidization mechanism because it has higher energy utilization efficiency and lower packing loss rate. This is because mechanical stirring causes the packing to form a fluidized state, which involves direct contact between the stirring blades and the packing, resulting in a relatively high packing loss rate.
[0005] However, the degree of aeration depends mainly on the location of the aerator. Compared with mechanical stirring to fluidize wastewater and packing material, the direction of aeration airflow is fixed, and the fluidization effect is weaker the further away from the aerator, resulting in uneven fluidization of the water. Some packing material with slight biofilm formation but a specific gravity greater than water will detach and float back to the surface during the sinking process due to the disturbance of the fluidized water. Most of the packing material with severe biofilm formation cannot detach on its own and falls into the aeration dead zone under the condition of disturbance of multiple aeration airflow directions, thus settling at the bottom of the packing tank and failing to perform normal reaction function. It is necessary to inspect the packing material regularly and clean it.
[0006] In view of the above-mentioned technical problems, we propose a wastewater treatment device for polyurethane rubber vulcanizing agent production. Summary of the Invention

[0009] [Technical Solution]
[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a wastewater treatment device for polyurethane rubber vulcanizing agent production, comprising a water treatment tank, an aerator is provided inside the water treatment tank, and multiple aerators are arranged at orderly intervals, and a packing flushing mechanism is also provided, which is at least used to transport the packing to the top of the aerator to cooperate with the aerator for flushing the packing, and a slope is also provided inside the water treatment tank to guide the packing to the part of the packing flushing mechanism.
[0011] Preferably, the water treatment tank can be any type of tank capable of accommodating and treating wastewater, and is not limited to any specific shape or structure. More preferably, in order to accommodate the orderly installation of aerators, the water treatment tank should be configured as a regular cubic structure as shown in the figure.
[0012] Preferably, the aerator is connected to an external air supply device, such as an air pump. Those skilled in the art can set up any air supply mechanism that they are familiar with and know in relation to the actual implementation situation. This will not be elaborated on further, nor will it be considered as a further limitation on the technical features of the invention.
[0013] Preferably, the orderly spacing of the aerators refers to the arrangement as follows: Figure 2 The matrix-like structure shown.
[0014] Preferably, the slope can be integrally formed at the bottom of the water treatment tank, or it can be a separate slope set in the water treatment tank. The bottom of the slope is connected to the part of the packing flushing mechanism, so that the packing sinks down and finally makes contact with the packing flushing mechanism.
[0015] Preferably, the packing flushing mechanism includes a pipe, and a conveying component for conveying the packing is provided inside the pipe. A partition is provided at one end of the pipe, which is located directly above the aerator and is configured to at least block the packing from flowing out of the flushing range during the flushing process of the aerator.
[0016] Preferably, the pipe is a cylindrical pipe with an opening at the upper end, through which the pipe is connected to the bottom of the water treatment tank.
[0017] Preferably, the conveying component is a helical blade. When there are multiple conveying components connected in series, the helical blades of the conveying components are fixedly connected together. One of the helical blades closest to the side of the water treatment tank can be a rotation drive mechanism that can drive the helical blade to rotate, such as a motor or a motor + reducer, which is known and understood by those skilled in the art. The helical blade should be dynamically sealed to the water treatment tank.
[0018] Preferably, those skilled in the art should understand that, in order to avoid disturbing the sludge at the bottom of the water treatment tank during the operation of the packing flushing mechanism, the rotation speed of the conveying component should be controlled to be sufficiently slow.
[0019] Preferably, the spacer includes a plurality of strips spaced apart to form gaps, the gaps being configured to allow only fluid and its admixtures other than the packing material to pass through.
[0020] Preferably, the gap is configured to allow only fluid and its admixtures outside the packing material to pass through, meaning that the size of the gap is smaller than the structural dimensions of the packing material, thereby creating a barrier to the packing material. In addition, the fluid refers to liquids in the water treatment tank, such as wastewater, and the fluid admixtures refer to dirt, such as sludge, that may be present in the wastewater.
[0021] Preferably, the spacer further includes a baffle for blocking the packing during the flushing process to prevent the packing from flowing out of the flushing range from the sides of the multiple strips.
[0022] Preferably, the spacers are arranged in two sets, one above the other, with the two baffles in each set distributed on opposite sides of the two outermost strips among the plurality of strips.
[0023] Preferably, the two baffles in the two sets of spacers are distributed on opposite sides of the two outermost strips among the plurality of strips, meaning that the two baffles form a configuration such that... Figure 7 The structure shown has the space between the two baffles and the multiple strips forming an effective scouring range for the packing material.
[0024] Preferably, the multiple strips in the two sets of partitions are staggered, and the multiple strips in a single set of partitions are connected to a connector. The partition is rotatable based on the connector and is configured such that the two sets of strips are fully engaged or partially engaged after being rotated via their corresponding connectors.
[0025] Preferably, when the spacers are distributed in two groups, the two groups of strips are arranged collinearly based on their annular axes, so that the strips in one group of spacers can completely overlap with the baffles in the other group of spacers after rotation. This completely overlapping state is the fully engaged state.
[0026] Preferably, when multiple sets of partitions are connected in series, the connecting members in the multiple sets of partitions are fixedly connected to each other. One of the connecting members closest to the water treatment tank extends from the inside of the water treatment tank to its outside and is dynamically sealed to it. The connecting member needs to form a circular movement path. Based on this, a dynamic sealing ring should be provided on the water treatment tank at the position corresponding to the connecting member.
[0027] Preferably, the mechanism of rotating the attached spacer by moving the connector in a ring can be achieved by manually moving the connector, or by using an external rotation drive to move the connector in a ring.
[0028] Preferably, the strip is annular, and the baffle in one of the partitions is configured to be non-circumferentially collinear with the strip based on its position, and the strip and the baffle can rotate synchronously. The baffle in the other partition is configured to be circumferentially collinear with the strip based on its position, and the baffle in the partition can disengage and rotate synchronously with the corresponding strip, so that when the two sets of strips are fully engaged, the baffle on the partition can rotate to be circumferentially collinear with the baffle in the other partition.
[0029] Preferably, the baffle and the strip in the partition are configured such that whether they are circumferentially collinear depends on their position, which means that they are in the structural state shown in the figure. In this state, under the premise that the structural dimensions of the baffle and the strip are comparable, the baffle and the annular strip are either circumferentially collinear or not.
[0030] Preferably, in one of the partitions where the positions are circumferentially collinear, a number of connecting members corresponding to the number of strips are provided on the connecting member, and a baffle and a connecting member are fixedly connected in the partition. In another partition, a number of connecting members corresponding to the number of strips in the partition where the positions are circumferentially collinear are also provided on the connecting member. A joint portion is provided on the strip corresponding to the two sets of connecting members, and is configured such that when the strip engages with its corresponding set of connecting members through the joint portion, the connecting member with the joint portion is used to control the rotation of the strip.
[0031] Preferably, the connecting member matches the structure of the corresponding connecting portion. For example, if the connecting member can be a pin, then the connecting portion corresponding to the pin is a slot that matches the pin structure.
[0032] Preferably, the number of connecting members corresponding to the number of strip-shaped members is fixedly connected to the connecting member two, and the connecting member two is slidably connected inside the connecting member one.
[0033] Preferably, when multiple sets of partitions are connected in series, under the premise that the connecting member 1 of the multiple sets of partitions is fixedly connected to each other, the connecting member 2 is also fixedly connected to each other, and the connecting member 2 closest to the water treatment tank extends from the inside of the water treatment tank to its outside and is controlled externally. For example, connecting member 2 and connecting member 1 can be configured as follows: Figure 8The structure shown is such that connector two is slidably connected to the interior of connector one, thereby maximizing the structural integration of connector one and connector two.
[0034] [Beneficial Effects]
[0035] Compared with the prior art, the present invention provides a wastewater treatment device for polyurethane rubber vulcanizing agent production, which has the following beneficial effects:
[0036] This wastewater treatment equipment for polyurethane rubber vulcanizing agent production guides the packing material, which has a higher specific gravity, to a packing flushing mechanism by a slope. The flushing mechanism, in conjunction with an aerator, flushes the packing material, causing it to float back to a suspended state. This achieves a self-circulating flushing process within the water treatment tank, primarily utilizing the change in the packing material's specific gravity. This process better reflects the actual circulation state of the packing material during implementation, ensuring the activity of the biofilm on the packing material and the uniform distribution of the packing material within the water treatment tank.

[0054] To make the technical means, creative features, achieved objectives, and functional effects of this invention readily understandable, the invention will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0055] To address the shortcomings of existing technologies, such as Figure 2 , 3 As shown, the present invention provides a wastewater treatment device for polyurethane rubber vulcanizing agent production, including a water treatment tank 1, an aerator 4 is provided inside the water treatment tank 1, and multiple aerators 4 are arranged at orderly intervals. It also includes a packing flushing mechanism 3, which is used at least to transport the packing material to the top of the aerators 4 to cooperate with the aerators 4 for flushing the packing material. A slope 2 is also provided inside the water treatment tank 1 to guide the packing material to the part of the packing flushing mechanism 3.
[0056] Among them, the water treatment tank 1 can be any kind of tank that can accommodate wastewater for treatment, and it is not limited to a specific shape and structure. Preferably, in order to accommodate the orderly installation of the aerators 4, the water treatment tank 1 should be set as a regular cubic structure as shown in the figure.
[0057] The aerator 4 is connected to an external air supply device, such as an air pump. Those skilled in the art can set up any air supply mechanism that they are familiar with and know in relation to the actual implementation. In this embodiment, it will not be described in detail, nor will it be regarded as a further limitation on the technical features of the invention.
[0058] The orderly spacing of the aerator 4 refers to the arrangement of elements such as... Figure 2 The matrix-like structure shown;
[0059] The slope 2 can be integrally formed at the bottom of the water treatment tank 1, or it can be an independent slope set in the water treatment tank 1. The bottom of the slope 2 is connected to the part of the packing flushing mechanism 3, so that the packing sinks down and finally makes contact with the packing flushing mechanism 3.
[0060] It should be noted that, in this embodiment, the water treatment process for industrial wastewater such as that generated from the production of polyurethane rubber vulcanizing agents mainly refers to the water treatment process in the MBBR process, that is, a certain amount of MBBR packing is added inside the water treatment tank 1. The density of this type of packing is close to that of water but smaller than that of water, so it can be suspended in water. By increasing the biomass and species of organisms in the water treatment tank 1, the treatment efficiency of wastewater is improved.
[0061] During wastewater treatment, aeration or stirring are performed in water treatment tank 1 to fluidize the suspended packing material, allowing activated sludge and an attached biofilm to form on the packing material. Figure 1 The structure shown can degrade pollutants such as organic matter, nitrogen, and phosphorus in water through metabolism;
[0062] In this embodiment, taking the fluidized state of the packing material formed by aeration in water using aerator 4 as an example, in actual implementation, the wastewater in the water treatment tank 1 is aerated by aerator 4 to at least form a sufficient mixture between the wastewater and the packing material.
[0063] During this process, after a certain degree and time of treatment, the amount of sludge increases to the point that it can no longer be suspended and thus sinks to the bottom of the water treatment tank 1. During the sinking process, some of the packing gradually sinks to the position close to the aerator 4, causing the sludge on it to fall off. Under the action of the aerator 4, it floats back to a suspended state. The sludge on some of the packing is not enough to fall off on its own during the sinking process. Then, during the sinking process, it falls through the slope 2 to the position of the packing flushing mechanism 3. Then, the packing flushing mechanism 3, in conjunction with the aerator 4, flushes this part of the packing.
[0064] Specifically, such as Figures 3-5 As shown, a filler flushing mechanism 3 for a wastewater treatment device for polyurethane rubber vulcanizing agent production is provided. The filler flushing mechanism 3 includes a pipe 31, and a conveying component 32 for conveying the filler is provided inside the pipe 31. A partition 33 is provided at one end of the pipe 31. The partition 33 is located directly above the aerator 4 and is configured to at least block the filler from flowing out of the flushing range during the flushing process of the aerator 4.
[0065] The pipe 31 is preferably a cylindrical pipe, and an opening is provided at the upper end of the pipe 31, through which the pipe 31 is connected to the bottom end of the water treatment tank 1.
[0066] It should be noted that this invention is a wastewater treatment device for polyurethane rubber vulcanizing agent production. Through the packing flushing mechanism 3, in the above embodiments, as shown... Figure 3 In the structural state shown, the sinking filler slides down along the slope 2 until it contacts the filler flushing mechanism 3. Since the partition 33 is located directly above the aerator 4, it will disturb the wastewater in the water treatment tank 1 during the normal operation of the aerator 4. Especially in the area directly above the aerator 4, i.e., the area where the partition 33 is installed, the sinking filler will not fall onto the partition 33, but will fall into the pipes 31 located on both sides of the partition 33.
[0067] Then, the packing material located inside the pipe 31 is transported to the position of the partition 33 by the conveying component 32. That is, the packing material is transported by the conveying component 32 to the position directly above the aerator 4. At this time, the distance between the packing material and the aerator 4 is sufficient to disturb the sludge on the packing material and form a flushing effect. At the same time, with the partition 33 in place, the packing material will not be forced to flow out of the flushing range during the flushing process of the aerator 4, but will always be effectively flushed by the airflow generated by the aerator 4, thus forming a complete flushing process for the packing material.
[0068] It is worth mentioning that the filler with increased specific gravity is guided to sink to the filler flushing mechanism 3 by the slope 2. Then, the filler flushing mechanism 3, together with the aerator 4, flushes the filler. After being effectively flushed, the filler floats back to a suspended state, thus realizing the self-circulating brushing of the filler inside the water treatment tank 1. The self-brushing process of the filler is mainly based on the change in specific gravity of the filler, which is more in line with the circulation state of the filler in the actual implementation process. This ensures the activity of the biofilm on the filler and the uniform distribution of the filler in the water treatment tank 1.
[0069] Those skilled in the art should understand that, in order to avoid disturbing the sludge at the bottom of the water treatment tank 1 during the operation of the packing flushing mechanism 3, the rotation speed of the conveying component 32 should be controlled to be sufficiently slow.
[0070] Specifically, and such as Figure 4 , 5 As shown, a conveying component 32 is used in the filler flushing mechanism 3 of a wastewater treatment equipment for polyurethane rubber vulcanizing agent production. The conveying component 32 is a helical blade. When there are multiple conveying components 32 connected in series, the helical blades of the conveying components 32 are fixedly connected together. One of the helical blades closest to the side of the water treatment tank 1 can be a rotating drive mechanism that can drive the helical blade to rotate, such as a motor or a motor + reducer, which is known and understood by those skilled in the art. The helical blade should be dynamically sealed to the water treatment tank 1.
[0071] It should be noted that the present invention is a wastewater treatment device for polyurethane rubber vulcanizing agent production. In this embodiment, the conveying component 32 is a spiral blade used as the conveying component 32 to convey the packing material located in the pipe 31. The advantage of the spiral blade is that it can drive the packing material to flow to the maximum extent and avoid unnecessary excessive pressure on the packing material, which may cause damage to the packing material.
[0072] In the above embodiment, since the packing material is blocked by a partition 33 such as a grid, and considering that the packing material needs to float back to a suspended state after being effectively flushed, in order to prevent the partition 33 from blocking the packing material and affecting its self-floating, the following is done:
[0073] Furthermore, such as Figure 7 As shown, a partition 33 for a wastewater treatment device for polyurethane rubber vulcanizing agent production includes a plurality of strips 331, which are spaced apart and form gaps. The gaps are configured to allow only fluids and their adjuncts other than the packing material to pass through.
[0074] The voids are configured to allow only fluid and its admixtures outside the packing material to pass through, meaning that the size of the voids is smaller than the structural dimensions of the packing material, thus creating a barrier to the packing material. In addition, the fluid refers to the liquid in the water treatment tank 1, such as wastewater, and the admixtures of the fluid refer to the dirt that may be present in the wastewater, such as sludge.
[0075] Its partition 33 also includes a baffle 332, which is used to block the packing during the flushing process to prevent the packing from flowing out of the flushing range from the sides of the multiple strips 331.
[0076] Two sets of spacers 33 are arranged vertically. The two baffles 332 in the two sets of spacers 33 are distributed on opposite sides of the two outermost strips 331 among the multiple strips 331.
[0077] Among them, the two baffles 332 in the two sets of partitions 33 are distributed on opposite sides of the two outermost strips 331 among the multiple strips 331, which means that the two baffles 332 form a structure as shown in the figure. Figure 7 The structure shown has the space between the two baffles 332 and the multiple strips 331 forming an effective scouring range for the packing material.
[0078] Furthermore, the spacer 33 has multiple strips 331 in two sets of spacers 33 with staggered positions, and multiple strips 331 in a single set of spacers 33 are connected to a connector 333. The spacer 33 is rotatable based on the connector 333 therein, and is configured such that the two sets of strips 331 are fully engaged or partially engaged after rotating via the corresponding connector 333.
[0079] When the spacer 33 is distributed in two groups, the two groups of strips 331 are arranged collinearly based on their annular axes, so that the strips 331 in one group of spacers 33 can completely overlap with the baffles 332 in the other group of spacers 33 after rotation. This completely overlapping state is the fully engaged state.
[0080] When multiple sets of partitions 33 are connected in series, the connecting members 333 in the multiple sets of partitions 33 are fixedly connected to each other. The connecting member 333 closest to the water treatment tank 1 passes through the inside of the water treatment tank 1 to its outside and is dynamically sealed to it. The connecting member 333 needs to form a circular movement path. Based on this, a dynamic sealing ring should be provided on the water treatment tank 1 at the position corresponding to the connecting member 333.
[0081] The mechanism of rotating the attached spacer 33 by moving the connector 333 in a circular motion can be achieved by manually moving the connector 333, or by using an external rotation drive to move the connector 333 in a circular motion.
[0082] Furthermore, the strip 331 is annular, and the baffle 332 in one partition 33 is configured to be non-circumferentially collinear with the strip 331 based on its position, and the strip 331 and the baffle 332 can rotate synchronously. The baffle 332 in the other partition 33 is configured to be circumferentially collinear with the strip 331 based on its position, and the baffle 332 in the partition 33 can disengage and rotate synchronously with the corresponding strip 331. This is so that when the two sets of strips 331 are fully engaged, the baffle 332 on the partition 33 can rotate to be circumferentially collinear with the baffle 332 in the other partition 33.
[0083] In this context, the baffle 332 and the strip 331 in the spacer 33 are configured such that whether they constitute circumferential collinearity based on their positional state refers to whether they constitute a collinearity as described above. Figure 7 The structure shown is such that, under the premise that the structural dimensions of the baffle 332 and the strip 331 are equivalent, the circumferential direction of the baffle 332 and the annular strip 331 are either collinear or not collinear in the circumferential direction.
[0084] It should be noted that this invention is a wastewater treatment device for polyurethane rubber vulcanizing agent production. In this embodiment, the partition 33 is used to, as shown in the example... Figure 7 Taking the structure shown as an example, in this structure, the spacer 33 is formed by multiple strips 331 arranged at equal intervals with a certain spacing. The multiple strips 331 are distributed in two sets, and their positions are staggered. In this structure, the gap between the multiple strips 331 forms a space that allows liquid to flow through the water treatment tank 1, while preventing the packing material from passing through the gap.
[0085] like Figure 7 In the structural state shown, the two sets of strips 331 distributed vertically form an upper and lower barrier to the packing material, while not affecting the normal flow of the airflow and liquid generated by the aerator 4. At the same time, two baffles 332 are located on both sides of the multiple strips 331 above, thus forming a complete barrier to the packing material, so that the packing material located between the two sets of strips 331 can be subjected to the scouring effect of the liquid carried by the airflow generated by the aerator 4 to the greatest extent.
[0086] After the packing material is effectively flushed, the sludge on it falls off. At this time, the specific gravity of the packing material is smaller than that of the wastewater in the water treatment tank 1, so it will be resuspended in the water.
[0087] Subsequently, in order for the flushed packing material to float to a suspended state and flow out from inside the partition 33, it is necessary to rotate one set of strips 331 to prevent them from obstructing the packing material located in the two sets of strips 331. For example, the upper set of strips 331 can be rotated to 180°, or the lower set of strips 331 can be rotated to 180°, until the two sets of strips 331 overlap.
[0088] When the upper set of strips 331 is rotated to 180°, that is, the upper set of strips 331 is rotated to overlap with the lower set of strips 331, there will be no obstruction above the packing, and the packing can float and flow on its own, especially under the acceleration and flow promotion effect of the aerator 4.
[0089] When the lower set of strips 331 is rotated 180°, that is, rotated so that it overlaps with the upper set of strips 331, the two sets of overlapping strips 331 act as a barrier to the packing material from above. However, at this time, one of the two baffles 332 is located below, and the other baffle 332 is located above. Figure 10 In the structure shown, the packing is in a floating state. In this state, the two sets of strips 331 form an obstruction above, and there is a baffle 332 on one side above and another baffle 332 on the other side above, thus forming a floating channel. Under the synergistic effect of the aerator 4, the packing that has been effectively flushed is accelerated to float up on its own.
[0090] It is worth mentioning that, during the process of guiding the packing to float, compared to rotating the set of strips 331 to 180° located above, considering that the airflow generated by the aerator 4 is disordered and causes a large disturbance to the packing, during the process of flushing the packing, some packing may not be completely and effectively flushed and may still have a specific gravity greater than the density of water. If the packing is guided to float by rotating the set of strips 331 to 180° located above, the packing that has not been completely and effectively flushed can still flow to a far position under the disturbance of the aerator 4, and re-enter the redundant process of sinking and needing to be transported by the conveyor 32 and then flushed.
[0091] Based on this, it is preferable that during the process of guiding the packing to float, a set of strips 331 located below is rotated to the top. In this way, the two sets of strips 331 overlap and are located above the packing, thus blocking the packing. At this time, the packing can only flow out from the side of the strips 331. The packing that is effectively flushed floats normally, while the packing that is not completely flushed flows into the pipe 31 on the side, waiting for the next batch of delivery to flush it again.
[0092] Based on the above implementation method, this implementation method mainly utilizes the operation mechanism of the strip 331 and the baffle 332 to further extend the function of the partition 33, aiming to transport a large amount of sludge at the bottom of the water treatment tank 1 to the outside. On the one hand, since the sludge will eventually settle to the bottom in the water treatment tank 1, it is necessary to transport the sludge out periodically for subsequent cleaning. On the other hand, in the above implementation method, since there is an aerator 4, the sludge deposition process is similar to the packing material sinking process mentioned above. That is, when the aerator 4 is operating normally, it will not fall onto the surface of the aerator 4 or even the area near it. Furthermore, the presence of the aerator 4 will interfere with the transport of sludge.
[0093] For example, in the above embodiment, the sludge mainly settles inside the pipe 31. Since the water inside the pipe 31 is more stable than the water in the area near the aerator 4, the sludge is transported by rotating the conveyor 32 inside the pipe 31. However, considering that the installation of the strip 331 and the baffle 332 may interfere with the transport of the sludge, the following measures are taken:
[0094] Furthermore, such as Figure 8 , 9 As shown, a partition 33 for treating wastewater from polyurethane rubber vulcanizing agent production includes a connector 333 in a partition 33 that is circumferentially collinear in position. A number of connecting members 3331 corresponding to the number of strip-shaped members 331 are provided on the connector 333 in the partition 33. A baffle 332 and the connector 333 are fixedly connected in the partition 33. Another partition 33 also has a connector 3331 on the connector 333 in the partition 33 that is circumferentially collinear in position. A joint portion 3311 is provided on the strip-shaped member 331 at a location corresponding to the two sets of connecting members 3331. The strip-shaped member 331 is configured such that when it engages with its corresponding set of connecting members 3331 via the joint portion 3311, the connector 333 with the connecting member 3331 controls the rotation of the strip-shaped member 331.
[0095] The connecting member 3331 and the corresponding connecting part 3311 are structurally matched. For example, the connecting member 3331 can be a pin, and the connecting part 3311 corresponding to the pin is a slot that matches the pin structure.
[0096] Furthermore, the number of connecting members 3331 corresponding to the number of strips 331 is fixedly connected to connecting member 2 3332, and connecting member 2 3332 is slidably connected inside connecting member 1 333.
[0097] When multiple sets of partitions 33 are connected in series, under the premise that the first connector 333 of the multiple sets of partitions 33 is fixedly connected to each other, the second connector 3332 is also fixedly connected to each other, and the second connector 3332 closest to the water treatment tank 1 extends from the inside of the water treatment tank 1 to its outside via external control. For example, the second connector 3332 and the first connector 333 can be configured as follows: Figure 8 The structure shown is such that connector 2 3332 is slidably connected to the inside of connector 1 333, thereby maximizing the structural integration of connector 1 333 and connector 2 3332.
[0098] It should be noted that this invention is a wastewater treatment device for polyurethane rubber vulcanizing agent production. In this embodiment, the partition 33 is used to adjust the structural state of the strip-shaped member 331 and the baffle 332 to the following condition: Figure 10 The sludge conveying configuration shown in the diagram utilizes a plate-like structure formed by two sets of strip-shaped members 331 located at the bottom. There are no baffles 332 obstructing the flow on either side of this plate-like structure; both baffles 332 are located at the top. Thus, as... Figure 10 In the structural state shown, the two sets of strips 331 constituting the plate-shaped member are located below and between two adjacent pipes 31. The plate-shaped member forms a continuous sludge conveying path between the two pipes 31. After this structural state is formed, the sludge can be continuously conveyed by rotating the conveying member 32 inside the pipe 31.
[0099] If it is necessary to adjust strip 331 and baffle 332 as follows: Figure 10 In the sludge conveying structure shown, after the two sets of partitions 33 form a floating packing state, by synchronously rotating the two sets of partitions 331 by 80° until both sets of strips 331 are located at the bottom, the baffle 332 in one set of partitions 33 where the strips 331 and baffles 332 are circumferentially collinear is located at the bottom. In this partition 33 where the strips 331 and baffles 332 are circumferentially collinear, by moving the connecting member 3331, the connecting member 3331 is disengaged from the corresponding strip. 331 forms a joint. At the same time, by moving the connecting member 3331 on another set of partitions 33 where the strip 331 and the baffle 332 are not circumferentially collinear, the connecting member 3331 on it forms a joint with the strip 331 in the partition 33 where the strip 331 and the baffle 332 are circumferentially collinear. Thus, the strip 331 in the partition 33 where the strip 331 and the baffle 332 are circumferentially collinear disengages from its attached connecting member 333 and forms a joint.
[0100] In this state, by rotating the connecting piece 333, the lower baffle 332 can be rotated independently until it rotates 180°, thus forming the configuration shown below. Figure 10The sludge conveying state shown is such that, in this structural state, both baffles 332 are located at the top and do not obstruct the conveying of sludge.
[0101] As those skilled in the art will understand, in actual implementation, since the pipe 31 is not completely closed, that is, the part of the pipe 31 facing the packing is open, the sludge should be transported slowly enough to avoid the sludge flowing disorderly due to excessive rotation speed. Preferably, the sludge transport process can be carried out after the wastewater inside the water treatment tank 1 is drained.
[0102] In the above implementation, the conveying component 32 mainly serves to slowly push the sludge. Considering that the sludge may not be able to flow efficiently in the part where the partition 33 is set between the pipes 31, a spiral blade can also be set in the part of the partition 33 without affecting the normal flushing of the packing material, so as to meet the continuity of sludge conveying.
[0103] In summary, the basic working principle of this invention is as follows:
[0104] During the wastewater treatment process, the packing material with increased specific gravity sinks and is guided by the slope 2 to the packing material flushing mechanism 3. It mainly sinks into the pipe 31. In the packing material flushing mechanism 3, the packing material located inside the pipe 31 is transported to the position of the partition 33 by the conveying component 32. Under the aeration of the aerator 4, it plays a role in flushing the packing material. The partition 33 is mainly used to form an effective flushing space for the packing material, so as to prevent the packing material from flowing unrestricted under the aeration of the aerator 4 and failing to form an effective flushing.
[0105] After being effectively flushed, the packing material floats normally. During this process, to ensure that the packing material can be effectively flushed, it should be confined at an appropriate distance from the aerator 4. This is achieved by rotating one set of partitions 33, so that this set of partitions 33 forms a configuration similar to that of another set of partitions 33. Figure 10 The packing scouring state shown allows the packing to be scourned to the maximum extent without affecting the normal flow of wastewater accelerated by aerator 4.
[0106] Then, if it is necessary to assist the packing material to float and flow, one set of partitions 33 is rotated until the strip-shaped piece 331 in one set overlaps with the strip-shaped piece 331 in another set of partitions 33. In this state, the two sets of strip-shaped pieces 331 are either above or below. When both sets of strip-shaped pieces 331 are above, only one baffle 332 exists above, and the other baffle 332 is below and will not obstruct the packing material. During the aerator 4 aeration towards the two sets of strip-shaped pieces 331 that constitute the plate-shaped piece, the fluid flow direction is as follows: Figure 10The arrow direction shown can guide the packing to float upwards based on the fluid direction, or when both sets of strips 331 are located below, the packing is unobstructed and can float upwards and flow out on its own.
[0107] If sludge needs to be transported, the partition 33 is rotated so that the strip 331 in the two sets of partitions 33 becomes a plate, and the plate needs to be located at the bottom. The baffle 332, which was originally located at the bottom, needs to be rotated to the top, so that a continuous transport path is formed between the two adjacent pipes 31. Based on this continuous transport path, the sludge can be continuously transported under the rotation of the transport member 32.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
