DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present utility model and to fully convey the scope of the present utility model to those skilled in the art.

[0030] As shown Figure 1 in the figure, a side view sectional schematic diagram of a sewage treatment device provided by an embodiment of the present utility model is shown. The sewage treatment device includes a device body 10, a baffle plate assembly 20, an input pipeline 30, and an output pipeline 40; the device body 10 is a sealed housing 11; one end of the sealed housing 11 is connected to the input pipeline 30, and the other end of the sealed housing 11 is connected to the output pipeline 40. A plurality of baffle plate assemblies 20 are arranged at intervals along a first direction X within the sealed housing 11, and the first direction X is the direction from the input pipeline 30 to the output pipeline 40; each baffle plate assembly 20 includes a rotating shaft 21 and a plurality of baffle plates 22; one end of the rotating shaft is movably connected to the inner wall of the sealed housing 11. Further referring to Figure 2 the figure, a top view schematic diagram of a baffle plate assembly in an embodiment of the present utility model is shown. The plurality of baffle plates 22 are respectively connected to the rotating shaft 21, so that the baffle plates 22 rotate under the drive of the rotating shaft 21, and the baffle plates 22 are perpendicular to the inner wall of the sealed housing 11 to which the rotating shaft 21 is connected.

[0031] In the related art, the treated sewage is directly discharged into the subsequent pipeline. When engineers sample and detect the relevant indicators of the treated sewage at the sampling point of the subsequent pipeline, the turbid treated sewage affects the judgment result of the engineers on the treated sewage. In some scenarios, a permeable membrane is installed in the pipeline to filter the treated sewage to remove the insoluble impurities or deposited salts in the treated sewage and reduce the turbidity of the treated sewage. However, the flow rate of the treated sewage is relatively fast, and the amount of insoluble impurities and deposited salts brought per unit time is large. Moreover, the filtering capacity of the permeable membrane is limited. Therefore, a large amount of undissolved residues will accumulate on the permeable membrane in a short time, reducing the efficiency of the permeable membrane or damaging the permeable membrane, and even causing the permeable membrane to be scrapped. For this reason, it is necessary to frequently stop the entire supercritical system to replace the permeable membrane, and frequently stopping the system will affect the service life and use efficiency of the supercritical system.

[0032] To this end, the embodiments of the present utility model provide a sewage treatment device. In the embodiments of the present utility model, after the treated sewage enters the sealed housing 11 of the sewage treatment device through the input pipe 30, it will impact the baffle 22 perpendicular to the inner wall in the baffle assembly 20. The rotating shaft 21 is movably connected to the inner wall of the sealed housing 11 through a bearing, so that the baffle assembly 20 rotates around the rotating shaft. The rotating baffle assembly 20 will disrupt the flow direction of the treated sewage passing through the baffle assembly 20, causing the flow direction of the treated sewage passing through the baffle assembly 20 to change relative to the overall flow direction of the treated sewage, thereby absorbing the kinetic energy of the treated sewage and slowing down the treated sewage when it passes through the baffle assembly 20. After deceleration by multiple spaced baffle assemblies 20, the flow rate of the treated sewage flowing through the entire sewage treatment device slows down. The insoluble substances suspended in the treated sewage are no longer directly carried to the output pipe 40 all at once, but instead stay in the sewage treatment device for a longer time. Therefore, there is a certain time for them to settle on the bottom plate of the sealed housing 11 of the sewage treatment device or on the baffle assembly 20. The content of insoluble substances suspended in the treated sewage entering the output pipe 40 will be significantly reduced, and correspondingly, the turbidity of the treated sewage will be lowered.

[0033] Furthermore, compared with directly discharging the treated sewage into the subsequent pipeline in the related art, the treated sewage with a higher flow rate and more insoluble substances has greater kinetic energy and will cause certain physical damage to the subsequent pipeline it impacts. After the action of the present utility model, the flow rate and the content of insoluble substances of the treated sewage will both decrease, and part of the kinetic energy is absorbed by the sewage treatment device, correspondingly reducing the impact damage to the subsequent pipeline.

[0034] Furthermore, multiple sewage treatment devices provided by the embodiments of the present utility model can be connected in series on the pipeline through which the treated sewage flows to decelerate the treated sewage multiple times, so that a certain amount of insoluble substances can settle in each sewage treatment device, achieving the effect of reducing the turbidity of the treated sewage multiple times.

[0035] In the embodiments of the present utility model, through the spaced baffle assemblies, the treated sewage passing through the sewage treatment device is decelerated, increasing the residence time of the insoluble substances in the sewage treatment device, making it easier for the insoluble substances to settle. In this way, the content of insoluble impurities suspended in the treated sewage entering the output pipe is reduced, thereby achieving the effect of reducing its turbidity, reducing the error in subsequent sampling and testing, and facilitating the corresponding compatibility operations for engineering personnel.

[0036] Optionally, as Figure 2As shown, it shows a top view schematic diagram of a baffle plate assembly in an embodiment of the present utility model. Among them, the baffle plate assembly further includes an ellipsoidal protrusion 23; there are four baffle plates 22;

[0037] The other end of the rotating shaft 21 is connected to the ellipsoidal protrusion 23. The baffle plates 22 are arranged at intervals along the axial direction of the rotating shaft 21. Among the four baffle plates 22, the angle between two adjacent baffle plates 22 arranged at intervals along the axial direction of the rotating shaft 21 is a right angle, so that in the top view perspective, the four baffle plates 22 are in a cross shape.

[0038] In a preferred solution of the embodiment of the present utility model, four baffle plates are used, and adjacent baffle plates are perpendicular to each other, forming a structure that is in a cross shape in the top view perspective. With this setting, while ensuring that the contact area between the treated sewage flowing from the input pipeline to the output pipeline and the baffle plate assembly is sufficient, the production cost of the baffle plate assembly is reduced; further, an ellipsoidal protrusion is provided at the end of the rotating shaft far from the inner wall of the sealing housing, so that the poorly soluble substances with unstable structures in the treated sewage near the center of the sealing housing are directly broken when the treated sewage impacts the protrusion as it impacts the protrusion, avoiding the continued agglomeration of such poorly soluble substances and affecting the operation of the equipment.

[0039] Optionally, as Figure 1 shown, the baffle plate 22 is in a bow-shaped structure. A bow-shaped structure refers to a shape composed of a chord and the arc opposite the chord. One side of the baffle plate 22 corresponding to the chord is connected to the rotating shaft 21, and a plurality of through holes 221 are arranged at intervals on the baffle plate 22.

[0040] In the embodiment of the present utility model, the baffle plates in the baffle plate assembly adopt a common bow-shaped structure. A bow is a shape composed of a chord and the arc opposite the chord. The bow-shaped baffle plate is the most commonly used baffle plate structure in the current market and is convenient for processing and forming. When constructing the baffle plate assembly, only the connection setting of one side of the chord in the bow-shaped baffle plate to the rotating shaft needs to be considered; further, the baffle plate can be set on the rotating shaft in a welded form, or a card slot can be opened in the axial direction of the rotating shaft, and the baffle plate is inserted into the rotating shaft along the axial card slot. At this time, grooves need to be opened at both ends of the side of the baffle plate corresponding to the chord so that the remaining part of the side of the baffle plate corresponding to the chord corresponds to the rotating shaft card slot; in the embodiment of the present utility model, a baffle plate with a plurality of through holes arranged at intervals is selected, so that when the treated sewage impacts the surface of the bow-shaped baffle plate, a part of the treated sewage can directly pass through the baffle plate without being blocked by the baffle plate. With this setting, while ensuring that the baffle plate assembly can rotate and disrupt the flow of the treated sewage after being impacted by the treated sewage, the damage caused by the impact of the treated sewage and the impurities in the treated sewage on the baffle plate is reduced.

[0041] As Figure 1As shown, the baffle plate assembly 20 includes an upper baffle plate assembly 201 spaced apart on the inner wall of the top plate of the sealed housing 11 and a lower baffle plate assembly 202 spaced apart on the inner wall of the bottom plate of the sealed housing 11. The spacing between the upper baffle plate assemblies 201 is the same as the spacing between the lower baffle plate assemblies 202.

[0042] In the embodiment of the present utility model, baffle plate assemblies are spaced apart on both the top plate and the bottom plate of the inner wall of the sewage treatment device, so that when the treated sewage fills the sealed housing of the sewage treatment device, the baffle plate assemblies can slow down the treated sewage flowing through the top plate and the bottom plate. That is, when the treated sewage flows through the sealed housing, the treated sewage located below the inside of the sealed housing will be slowed down by the lower baffle plate assembly, and the treated sewage located above the inside of the sealed housing will be slowed down by the upper baffle plate assembly; the spacing between the upper baffle plate assemblies is the same as the spacing between the lower baffle plate assemblies, so that the changes in the treated sewage passing through the upper baffle plate assemblies and the lower baffle plate assemblies tend to be the same, and thus the deceleration effects of the upper baffle plate assembly and the lower baffle plate assembly are similar.

[0043] As Figure 3 shown, a top view cross-sectional schematic diagram of a sewage treatment device provided by an embodiment of the present utility model is shown. The upper baffle plate assemblies are spaced apart along the first direction X on the inner wall of the top plate of the sealed housing ( Figure 3 not shown in the figure), and in a top view perspective, all the upper baffle plate assemblies are flush-mounted ( Figure 3 not shown in the figure). The lower baffle plate assemblies 202 are spaced apart along the first direction X on the inner wall of the bottom plate of the sealed housing 11, and in a top view perspective, all the lower baffle plate assemblies 202 are flush-mounted.

[0044] In a preferred solution of the embodiment of the present utility model, the upper baffle plates are spaced apart on the central axis of the inner wall of the top plate, and the lower baffle plates are spaced apart on the central axis of the inner wall of the floor. That is, all the upper baffle plate assemblies are flush-mounted and spaced apart, and all the lower baffle plate assemblies are flush-mounted and spaced apart. By flush-mounting the baffle plate assemblies, the treated sewage flowing in the first direction can impact the baffle plate assemblies multiple times, and each impact on the baffle plate assembly will slow it down, achieving a multiple deceleration effect.

[0045] As Figure 4 shown, a top view cross-sectional schematic diagram of another sewage treatment device provided by an embodiment of the present utility model is shown. The upper baffle plate assemblies are spaced apart along the first direction X on the inner wall of the top plate of the housing ( Figure 4 not shown in the figure), and are staggered along the second direction Y on the inner wall of the top plate of the sealed housing ( Figure 4(not shown in the figure), the lower baffle plate assembly 202 is arranged at intervals along the first direction X on the inner wall of the bottom plate of the sealed housing 11, and is arranged staggeredly along the second direction Y on the inner wall of the bottom plate of the sealed housing 11. The second direction Y is the direction perpendicular to the first direction X in the top view.

[0046] In another solution of the embodiment of the present invention, the upper baffle plates are arranged staggeredly at intervals on both sides of the central axis of the inner wall of the top plate, and the lower baffle plates are arranged staggeredly at intervals on both sides of the central axis of the inner wall of the floor, that is, arranged at intervals in the first direction and staggered in the second direction. By arranging the baffle plate assemblies staggeredly, it is also possible to make the treated sewage flowing along the first direction impact the baffle plate assemblies multiple times. Each time the baffle plate assemblies are impacted, their speed will be reduced, achieving the effect of multiple speed reductions. Compared with the preferred solution of the embodiment of the present invention, in this solution, the connection positions of the baffle plate assemblies and the inner wall of the sealed housing need to first determine the central axis of the sealed housing and perform multiple positionings accordingly, increasing the process.

[0047] Optionally, as Figure 1 shown, the upper baffle plate assembly 201 and the lower baffle plate assembly 202 are arranged staggeredly at intervals.

[0048] In the embodiment of the present invention, the upper baffle plate assembly and the lower baffle plate assembly are arranged staggeredly at intervals, so that all the baffle plate assemblies form a bent space in the sealed housing, forcing the treated sewage that impacts the baffle plate assemblies and changes its flow direction to flow according to the bent space formed by the upper and lower baffle plates arranged staggeredly at intervals, so that the treated sewage can contact the upper baffle plate assembly and the lower baffle plate assembly multiple times, increasing the contact time between the treated sewage and the baffle plate assemblies, and enabling the baffle plate assemblies to fully play the role of decelerating the treated sewage.

[0049] Optionally, as Figure 1 shown, a scale inhibitor inlet 111 is provided at a position on the top plate of the sealed housing 11 close to the input pipe 30.

[0050] In an embodiment of the present utility model, a scale inhibitor inlet is provided at a position on the top plate of the sealed housing near the input pipeline for adding scale inhibitor to the inside of the sealed housing. After the insoluble substances in the treated sewage settle down, they are likely to scale on the baffle plate assembly or the bottom plate of the sealed housing. The treated sewage has the physical property of high temperature, which also easily causes the precipitation of salt ions in the treated sewage and scales on the baffle plate assembly or the inner wall of the sealed housing. The dirt will adhere to the baffle plate assembly or the inner wall of the sealed housing, and even enter the connection position between the rotating shaft and the inner wall of the sealed housing, affecting the rotation of the baffle plate assembly, and further affecting the deceleration ability of the sewage treatment device. In addition, these dirt will also corrode the contacted equipment. After long-term accumulation, there is a risk of damaging the sewage treatment device. Therefore, the present utility model opens a scale inhibitor inlet at a position near the input pipeline, can add scale inhibitor into the sealed housing, and let the scale inhibitor diffuse to the whole inside of the sealed housing along the flowing direction of the treated sewage, removing various dirt adhering to the inner wall of the sealed housing and the baffle plate assembly, and preventing the adhered dirt from affecting the operation of the baffle plate assembly or corroding the sewage treatment device.

[0051] Optionally, as Figure 1 shown, the device body 10 is communicated with both the input pipeline 30 and the output pipeline 40 through flanges 12

[0052] In an embodiment of the present application, the entire sewage treatment device is communicated with the input pipeline and the output pipeline through flanges, that is, the sewage treatment device can be freely disassembled and assembled relative to the pipeline. The sewage treatment device can be added at multiple positions as needed. Only the corresponding flanges need to be installed on the pipeline at the added position to connect the sewage treatment device to the pipeline.

[0053] Optionally, as Figure 1 shown, a slag discharge port 112 is provided at a position on the bottom plate of the sealed housing 11 away from the input pipeline 30.

[0054] In an embodiment of the present utility model, a slag discharge port is provided at a position on the bottom plate of the sealed housing away from the input pipeline for collecting and discharging the settled insoluble substances; the settled insoluble substances after deceleration will slowly accumulate. Therefore, it is necessary to clean the inside of the sealed housing. In order to avoid frequently disassembling the sewage treatment device for internal cleaning, the present utility model opens a slag discharge port at the position of the bottom plate of the sealed housing away from the input pipeline, so that the settled insoluble substances reach the slag discharge port along the flowing direction of the treated sewage, and are collected and discharged from the sealed housing through the slag discharge port; further, after the slag discharge port is provided, the scale inhibitor can also prevent the insoluble substances from accumulating and caking at the slag discharge port and blocking the slag discharge port. By setting the slag discharge port, the settled insoluble substances can be discharged immediately, avoiding the problem of frequently disassembling the sewage treatment device for cleaning.

[0055] Optionally, as Figure 1As shown in the figure, a cooling device is provided on the outer surface of the sealed housing 11. The cooling device includes a nozzle 113, and the spraying direction of the nozzle 113 faces the outer surface of the sealed housing 11

[0056] In the embodiment of the present utility model, a cooling device is provided on the outer surface of the sealed housing to cool the sealed housing. Specifically, it is a nozzle whose spraying direction faces the sealed housing, used to spray water on the sealed housing for cooling; the treated sewage has the physical property of high temperature, and together with the salt ions and insoluble substances in the treated sewage, it will accelerate the corrosion of the sewage treatment device and the subsequent pipelines. Therefore, the present utility model provides a cooling water nozzle outside the sealed housing, and the waste heat of the treated sewage is taken away by the cooling water sprayed on the outer surface of the sealed housing to achieve the purpose of cooling and play a role in slowing down the corrosion

[0057] Optionally, as Figure 5 shown, a side view schematic diagram of another baffle plate assembly in the embodiment of the present utility model is shown. The baffle plate assembly can also be arranged in the following way: a plurality of baffle plates 22 are integrated and arranged spirally upward along the rotating shaft 21

[0058] In another embodiment of the present utility model, a plurality of baffle plates can also be integrated to form a spiral baffle plate that spirally rises around the rotating shaft. It can be understood that the spiral rise here means from the inner wall of the sealed housing towards the center of the sealed housing; compared with the baffle plate assembly implementation shown in Figure 2 As shown, this scheme has higher processing and production requirements; when the spiral baffle plate faces the impact of the treated sewage, it will also rotate driven by the rotating shaft. At the same time, the spiral structure enables the baffle plate assembly to make the treated sewage passing through move along the spiral to both sides of the radial center of the rotating shaft, and can also change the flow direction of the treated sewage passing through the baffle plate assembly later, making it different from the flow direction of the treated sewage flowing through the sewage treatment device as a whole, disturbing the flow of the treated sewage flowing through the sewage treatment device as a whole, achieving the effect of deceleration, so that the insoluble substances in the treated sewage stay in the sealed housing for a longer time for sedimentation, playing a role in reducing the turbidity of the treated sewage

[0059] In the embodiment of the utility model, by arranging a plurality of rotatable baffle plate assemblies at intervals up and down inside the sealed housing, the flow of the sewage after being processed by the baffle plate assemblies is disturbed, the overall flow rate of the sewage after being processed by the sewage treatment device is reduced, and the insoluble substances in the processed sewage are more likely to settle in the sealed housing of the sewage treatment device, thereby reducing the turbidity of the processed sewage and reducing the physical damage of the processed sewage to the pipeline. In addition, the utility model also arranges a scale inhibitor inlet and a slag discharge port on the sealed housing, so that the settled insoluble substance residues can be discharged in time without adhering to the internal structure of the sealed housing and affecting the various components arranged inside the sealed housing. A flange structure is arranged at the connection of the sewage treatment device and the input pipeline and the output pipeline, which is convenient for the addition, installation and disassembly of the sewage treatment device. A cooling water nozzle is arranged on the outer wall of the sealed housing to reduce the temperature of the processed sewage and reduce the corrosion of the processed sewage to the equipment. The structure of the utility model is simple and convenient for processing, can significantly reduce the turbidity of the processed sewage, reduce the error of subsequent sampling and detection work, is beneficial to the accurate progress of the compatibility operation, and is convenient for the reuse of sewage.
