Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and in particular to an energy-saving industrial circulating water treatment device. Background Art

[0002] Industrial circulating water refers to water used in industrial production processes that is treated and then recycled, such as cooling water and equipment circulating water. Its primary purpose is to conserve water resources, reduce costs, and minimize emissions. During long-term circulation, industrial circulating water experiences continuous evaporation, which concentrates salts. Furthermore, as cooling water comes into contact with the atmosphere, dissolved oxygen and bacterial levels increase. This can lead to varying degrees of inorganic salt deposition, metal corrosion, and the growth of bacteria, algae, and microorganisms. These hazards can result in reduced heat exchange efficiency, pipe blockage, and system corrosion in heat exchange equipment. Therefore, industrial circulating water treatment is essential.

[0003] A common treatment method is to add flocculants to circulating water. The colloids and dispersed particles of suspended matter in the circulating water form flocs under the interaction of molecular forces. During the sedimentation process, they collide and agglomerate, their size and mass continuously increasing. Once the flocs grow to a certain volume, they separate from the water phase under the action of gravity to form a lower sedimentation layer. The upper clear water layer is then introduced into industrial circulation equipment through an outlet pipe for use. For example, patent document CN209065628U discloses a modular integrated circulating water treatment device, including a sedimentation tank, a filtration tank, and a disinfection tank. The sedimentation tank has a dosing port at the upper end, a motor is located to the right of the dosing port, and a rotating shaft is located at the output end of the motor, which extends into the sedimentation tank.

[0004] When treating circulating water, the aforementioned circulating water treatment device adds flocculant to the dosing port. A motor drives the rotating shaft to mix the flocculant with the circulating water. The colloids and dispersed particles of suspended matter in the circulating water form flocs, which then descend to the bottom of the sedimentation tank under their own gravity, forming an upper water layer and a lower sludge layer. The lower sludge can be discharged through the drain port, and the upper water layer is collected, treated, and recycled again. However, because the circulating water in the sedimentation tank is flowing, the flocculant is not fully mixed with the circulating water after addition, and may flow into the filtration tank for filtration before flocs are formed. This results in suboptimal flocculation and sedimentation of the circulating water, which in turn affects the treatment of the circulating water. Summary of the Invention

[0005] In view of this, the present invention provides an energy-saving industrial circulating water treatment device to solve the technical problem that after the reagent is added to the flowing circulating water, it is not fully mixed with the circulating water, resulting in unsatisfactory flocculation and sedimentation effect of the circulating water.

[0006] To solve the above technical problems, the present invention provides an energy-saving industrial circulating water treatment device, comprising a reaction tank provided with a dosing port, a stirring mechanism disposed in the reaction tank, and a sedimentation tank connected to the reaction tank, wherein the reaction tank comprises a first reaction tank and a second reaction tank disposed in the first reaction tank, and the first reaction tank and the second reaction tank are alternately connected to the sedimentation tank; One side of the sedimentation tank is the water inlet end, and the other side is the water outlet end. A connecting frame is slidably connected in the sedimentation tank. A linear drive is provided on one side of the sedimentation tank to drive the connecting frame to move. Multiple partitions are installed at intervals near the water inlet end of the connecting frame. Multiple inclined plates are installed at intervals below the partition in the sedimentation tank. The up and down sliding of the partition allows the partition to be inserted into the gap between two adjacent inclined plates and the inclined plate can be inserted into the gap between two adjacent partitions.

[0007] By adopting the above technical solution, reaction tank one and reaction tank two alternately supply water to the sedimentation tank, which prolongs the reaction time of the reagent and the circulating water, is conducive to the full mixing of the reagent and the circulating water, and improves the flocculation effect. At the same time, partition plate one and inclined plate one are provided to further mix the circulating water and the reagent during the flow process, which is conducive to improving the flocculation effect of the circulating water, and can also slow down the impact force of the water flow, reduce the floating of the sediment at the bottom of the sedimentation tank, and help improve the sedimentation effect. Specifically, reaction tank one and reaction tank two are used to mix reagents and circulating water, and reaction tank one and reaction tank two alternately supply water to the sedimentation tank. For example, when reaction tank one is in the state of supplying water to the sedimentation tank, the circulating water enters reaction tank two and mixes with the reagent. When the water in reaction tank one is transported to the sedimentation tank, the circulating water and reagent in reaction tank two are mixed. Then, reaction tank two is in the state of supplying water to the sedimentation tank, and the circulating water enters reaction tank one and mixes with the reagent. Such alternating circulation can not only keep the sedimentation tank in a continuous water inflow state, but also prolong the reaction time of the reagent and the circulating water in reaction tank one or reaction tank two, which is conducive to the full mixing of the reagent and the circulating water. The linear actuator drives the connecting frame to move upward, leaving a gap between the lower end surface of the partition one and the upper end surface of the inclined plate one. The mixed water enters the water inlet end of the sedimentation tank and passes through the gap between two adjacent partitions and the gap between two adjacent inclined plates in turn. The partition one and the inclined plate one are staggered to further mix the circulating water and the reagent during the flow process, which is beneficial to improving the flocculation effect of the circulating water. At the same time, it can slow down the impact force of the water flow, reduce the floating of the sediment at the bottom of the sedimentation tank, and help improve the sedimentation effect.

[0008] Preferably, a delivery pipe is installed below reaction tank one and reaction tank two, and the end of the delivery pipe is connected to a water distribution tank. The water distribution tank is located in the sedimentation tank near the water inlet end, and multiple water outlets are provided on the side of the water distribution tank. An electromagnetic valve is installed on the delivery pipe to control the alternating connection between reaction tank one and reaction tank two and the sedimentation tank.

[0009] By adopting the above technical solution, the water in reaction tank one and reaction tank two that has reacted with the reagent enters the sedimentation tank through the delivery pipe. The solenoid valve controls the alternating connection between reaction tank one and reaction tank two and the sedimentation tank. The water in the delivery pipe enters the water distribution tank and reaches the sedimentation tank through multiple water outlets. This can slow down the impact force of the water flow, reduce the floating of sediment at the bottom of the sedimentation tank, and help improve the sedimentation effect.

[0010] Preferably, a plurality of partition plates 2 are installed at intervals on the connecting frame, and the partition plates 2 extend from a position close to the water outlet end to a position close to the partition plate 1. A plurality of inclined plates 2 are installed at intervals below the sedimentation tank at the lower part of the partition plates 2. The up and down sliding of the partition plates 2 allows the partition plates 1 to be inserted into the gap between two adjacent inclined plates 2 and the inclined plates 2 to be inserted into the gap between two adjacent partition plates 2. A baffle is also installed between the inclined plates 1 and 2.

[0011] By adopting the above technical solution, the linear drive drives the connecting frame to move upward, leaving a gap between the lower end surface of partition two and the upper end surface of inclined plate two. The water flowing out from the gap of inclined plate one passes through the baffle and in turn passes through the gap between the two adjacent inclined plates two, the gap between inclined plate two and partition two, and is then discharged from the water outlet. Partition two and inclined plate two block suspended matter in the water, which is beneficial to improving the cleanliness of the discharged water. The linear drive drives the connecting frame to move downward, and the connecting frame drives partition one and partition two to move downward, so that partition one is inserted into the gap between two adjacent inclined plates one, and inclined plate one is inserted into the gap between two adjacent inclined plates one. Partition one can scrape off the sediment on the surface of inclined plate one, and inclined plate one can scrape off the sediment on the surface of partition one. Similarly, partition two is inserted into the gap between two adjacent inclined plates two, and inclined plate two is inserted into the gap between two adjacent inclined plates two. Partition two can scrape off the sediment on the surface of inclined plate two, and inclined plate two can scrape off the sediment on the surface of partition two, which helps to clean partition one, partition two, inclined plate one and inclined plate two, reduce the blockage of the gaps therebetween, and allow water to flow smoothly.

[0012] Preferably, partition 1, inclined plate 1, partition 2 and inclined plate 2 are all inclined, a slide groove is inclined on the inner wall of the sedimentation tank, and a slide rod 1 that can slide in the slide groove is fixedly connected to the connecting frame.

[0013] By adopting the above technical solution, the water flows through the gap between two adjacent partition plates 1, the gap between two adjacent inclined plates 1, the gap between two adjacent inclined plates 2, and the gap between inclined plate 2 and partition plate 2 in sequence. Partition plate 1, inclined plate 1, partition plate 2 and inclined plate 2 are all inclined, which increases the stroke of the water flow, is beneficial to the full mixing of the reagent and the circulating water, and is beneficial to blocking the suspended matter on the surface of the water body after flocculation, thereby improving the water quality.

[0014] Preferably, the upper end surfaces of the inclined plate 1 and the inclined plate 2 are both herringbone-shaped.

[0015] By adopting the above technical solution, the upper end surfaces of inclined plate 1 and inclined plate 2 are both herringbone-shaped, which reduces the accumulation of sediment scraped off partitions 1 and 2 and helps the sediment fall into the sedimentation tank.

[0016] Preferably, a plurality of water outlet holes are provided on the side wall of the sedimentation tank at the water outlet end, and a water outlet trough is provided below the water outlet holes.

[0017] By adopting the above technical solution, the water flowing out from the gap between the inclined plate 2 and the partition plate 2 flows into the water outlet trough through the water outlet hole, so as to be easily transferred to the next processing process.

[0018] Preferably, a water baffle is slidingly provided in the sedimentation tank and can block the water outlet. A guide groove is provided on the sedimentation tank. A guide member that can slide in the guide groove is connected to the bottom of the water baffle. A bending groove is provided on the upper part of the connecting frame. A slide rod 2 that can slide in the bending groove is provided on the upper part of the baffle. A sewage outlet is provided on the side wall of the sedimentation tank adjacent to the water outlet. After the connecting frame drives the water baffle to descend, the water baffle blocks the water outlet, and the water level in the sedimentation tank rises, so that suspended matter on the water surface can be discharged through the sewage outlet.

[0019] By adopting the above technical solution, when it is necessary to clean partition one, inclined plate one, partition two and inclined plate two, the linear drive drives the connecting frame to descend, the bending groove presses down the slide bar two, so that the water baffle moves downward, and the guide part of the water baffle slides downward along the guide groove. The water baffle blocks the water outlet, the water level in the sedimentation tank rises, and the suspended matter on the water surface is discharged through the sewage outlet, which helps to improve the water quality.

[0020] Preferably, a screw is provided above the connecting frame, a screw slider is provided on the screw, a push plate is fixedly connected to the screw slider and can push the suspended matter on the water surface toward the side close to the sewage outlet, and a drive motor that can drive the screw to rotate is installed on one side of the sedimentation tank.

[0021] By adopting the above technical solution, after the linear drive drives the connecting frame to descend, the water baffle blocks the water outlet, the water level in the sedimentation tank rises, and the drive motor is started. The drive motor drives the screw to rotate, so that the screw slider drives the push plate to move. The push plate pushes the suspended matter on the water surface to the sewage outlet and discharges it through the sewage outlet, which helps to improve the water quality.

[0022] The beneficial effects of the above technical solution of the present invention are as follows: 1. The reaction tank 1 and the reaction tank 2 of the present invention alternately supply water to the sedimentation tank, which prolongs the reaction time of the reagent and the circulating water, is conducive to the full mixing of the reagent and the circulating water, and improves the flocculation effect. At the same time, the partition plate 1 and the inclined plate 1 are provided to further mix the circulating water and the reagent during the flow process, which is conducive to improving the flocculation effect of the circulating water, and can also slow down the impact force of the water flow, reduce the floating of the sediment at the bottom of the sedimentation tank, and help improve the sedimentation effect.

[0023] 2. The water flowing out from the gap between two adjacent inclined plates 1 passes through the baffle in turn through the gap between two adjacent inclined plates 2, and the gap between inclined plate 2 and partition 2, and is then discharged from the water outlet. Partition 2 and inclined plate 2 block suspended matter in the water, which is beneficial to improving the cleanliness of the discharged water; the linear drive drives the connecting frame to move downward, and the connecting frame drives partition 1 and partition 2 to move downward, so that partition 1 is inserted into the gap between two adjacent inclined plates 1, inclined plate 1 is inserted into the gap between two adjacent partitions 1, partition 2 is inserted into the gap between two adjacent inclined plates 2, and inclined plate 2 is inserted into the gap between two adjacent partitions 2, which helps to clean partition 1, partition 2, inclined plate 1 and inclined plate 2, reduce the blockage of the gaps therebetween, and allow water to pass smoothly.

[0024] 3. After the linear drive drives the connecting frame to descend, the water baffle blocks the water outlet, the water level in the sedimentation tank rises, and the drive motor is started. The drive motor drives the screw to rotate, so that the screw slider drives the push plate to move. The push plate pushes the suspended matter on the water surface to the sewage outlet and discharges it through the sewage outlet, which helps to improve the water quality.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figures 1-8 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments derived by ordinary technicians in this field fall within the scope of protection of the present invention.

[0028] Example This embodiment provides an energy-saving industrial circulating water treatment device, such as Figure 1 As shown, it includes a reaction tank 1, a sedimentation tank 3 and a stirring mechanism 2.

[0029] like Figure 1 As shown, the reaction tank 1 includes a reaction tank 11 and a reaction tank 2 12 arranged in the reaction tank 1 11 , and both the reaction tank 1 11 and the reaction tank 2 12 are provided with a dosing port and a water inlet.

[0030] like Figure 1 As shown, the stirring mechanism 2 includes a stirring frame 1 21 , a stirring frame 22 and a driving unit 23 .

[0031] like Figure 1 As shown, stirring rack 1 21 is positioned between reaction tank 1 11 and reaction tank 2 12, while stirring rack 2 22 is positioned within reaction tank 2 12. A connector 24 connects stirring rack 1 21 and stirring rack 2 22, allowing a drive unit 23 to rotate stirring rack 2 22 while simultaneously achieving synchronous rotation of stirring rack 1 21 and stirring rack 2 22. The stirring of stirring rack 1 21 and stirring rack 2 22 facilitates thorough mixing of the circulating water and reagents within reaction tanks 1 11 and 2 12. Drive unit 23 is driven by a motor, which is conventional technology and will not be described in detail.

[0032] like Figure 1 As shown, sedimentation tank 3 is disposed below reaction tank 1 11 , and a sewage pipe 33 is provided below sedimentation tank 3 . A delivery pipe 4 is installed below reaction tank 1 11 and reaction tank 2 12 . One end of delivery pipe 4 is provided with two branches, which are connected to reaction tank 1 11 and reaction tank 2 12 , respectively. The other end of delivery pipe 4 extends into sedimentation tank 3 . Circulating water mixed with the reagent in reaction tanks 1 11 and 2 12 is delivered to sedimentation tank 3 via delivery pipe 4 .

[0033] like Figure 1 and Figure 2 As shown, solenoid valves 41 are installed on both branches, and solenoid valves 41 are interconnected with controller signals. When one solenoid valve 41 is open, the other solenoid valve 41 is closed, so that reaction tank 1 11 and reaction tank 2 12 alternately supply water to sedimentation tank 3. For example, when reaction tank 1 11 is in the state of supplying water to sedimentation tank 3, the circulating water enters reaction tank 2 12 and mixes with the reagent. When the water in reaction tank 1 11 is completely transported to sedimentation tank 3, the circulating water in reaction tank 2 12 and the reagent are completely mixed. Then, reaction tank 2 12 is in the state of supplying water to sedimentation tank 3, and the circulating water enters reaction tank 1 11 and mixes with the reagent. This alternating cycle not only keeps sedimentation tank 3 in a continuous water inflow state, but also prolongs the reaction time between the reagent and the circulating water in reaction tank 1 11 or reaction tank 2 12, which is conducive to the thorough mixing of the reagent and the circulating water.

[0034] like Figure 1 As shown, one side of the sedimentation tank 3 is the water inlet end 31, and the other side is the water outlet end 32. The end of the delivery pipe 4 extending into the sedimentation tank 3 is connected to a water distribution tank 42, which is located in the sedimentation tank 3 near the water inlet end 31. Figure 6 As shown, a plurality of water outlets 43 are provided on the side of the water distribution box 42. The water reaches the sedimentation tank 3 through the plurality of water outlets 43, which can slow down the impact of the water flow, reduce the floating of the sediment at the bottom of the sedimentation tank 3, and help improve the sedimentation effect.

[0035] like Figure 3 and Figure 4 As shown, a connecting frame 5 is slidably connected in the sedimentation tank 3, and a linear driver 59 is provided on one side of the sedimentation tank 3 to drive the connecting frame 5 to move. The linear driver 59 is a hydraulic cylinder. A slide groove 52 is inclined on the inner wall of the sedimentation tank 3, and a slide rod 51 that can slide in the slide groove 52 is fixedly connected to the connecting frame 5.

[0036] like Figure 3As shown, a plurality of partitions 53 are installed at intervals near the water inlet end 31 on the connecting frame 5, and a plurality of inclined plates 54 are installed at intervals below the partitions 53 in the sedimentation tank 3. The partitions 53 slide up and down so that the partitions 53 can be inserted into the gap between two adjacent inclined plates 54 and the inclined plates 54 can be inserted into the gap between two adjacent partitions 53. The structure of the connecting frame 5 is shown in FIG. Figure 7 shown.

[0037] like Figure 3 As shown, a plurality of partition plates 55 are installed at intervals on the connecting frame 5, and the partition plate 55 extends from a position close to the water outlet end 32 to a position close to the partition plate 1 53. A plurality of inclined plates 56 are installed at intervals below the sedimentation tank 3 at the lower part of the partition plate 2 55. The up and down sliding of the partition plate 2 55 allows the partition plate 1 53 to be inserted into the gap between two adjacent inclined plates 2 56 and the inclined plate 2 56 to be inserted into the gap between two adjacent partition plates 2 55. A baffle 57 is also installed between the inclined plates 1 54 and 56. The length of the baffle 57 in the up and down directions is greater than the length of the inclined plates 1 54 and 56 in the up and down directions.

[0038] like Figure 3 As shown, linear actuator 59 drives connecting frame 5 upward, creating a gap between the lower end surface of partition 1 53 and the upper end surface of inclined plate 1 54, and a gap between the lower end surface of partition 2 55 and the upper end surface of inclined plate 2 56. The mixed water enters the water inlet 31 of sedimentation tank 3 and passes sequentially through the gap between two adjacent partitions 1 53 and the gap between two adjacent inclined plates 1 54. The staggered arrangement of partitions 1 53 and inclined plates 1 54 further mixes the circulating water and the reagent during flow, which helps improve the flocculation effect of the circulating water. At the same time, it can reduce the impact force of the water flow, reduce the floating of sediment at the bottom of sedimentation tank 3, and improve the sedimentation effect.

[0039] like Figure 3 As shown, the water flowing out from the gap between two adjacent inclined plates 1 54 passes through the baffle 57 and in turn passes through the gap between two adjacent inclined plates 2 56, the gap between inclined plate 2 56 and partition 2 55, and then is discharged from the water outlet 32. The partition 2 55 and inclined plate 2 56 block the suspended matter in the water, which is beneficial to improving the cleanliness of the discharged water. The linear actuator 59 drives the connecting frame 5 to move downward, as shown in FIG. Figure 6As shown, the connecting frame 5 drives the partition 1 53 and the partition 2 55 to move downward, so that the partition 1 53 is inserted into the gap between the two adjacent inclined plates 1 54, and the inclined plate 1 54 is inserted into the gap between the two adjacent partitions 1 53. The partition 1 53 can scrape off the sediment on the surface of the inclined plate 1 54, and the inclined plate 1 54 can scrape off the sediment on the surface of the partition 1 53. Similarly, the partition 2 55 is inserted into the gap between the two adjacent inclined plates 2 56, and the inclined plate 2 56 is inserted into the gap between the two adjacent partitions 2 55. The partition 2 55 can scrape off the sediment on the surface of the inclined plate 2 56, and the inclined plate 2 56 can scrape off the sediment on the surface of the partition 2 55, which helps to clean the partition 1 53, the partition 2 55, the inclined plate 1 54 and the inclined plate 2 56, reduce the blockage of the gaps therebetween, and allow water to flow smoothly.

[0040] like Figure 3 As shown, partition 1 53, inclined plate 1 54, partition 2 55 and inclined plate 2 56 are all inclined to increase the stroke of the water flow, which is beneficial to the full mixing of the reagent and the circulating water and to the blocking of suspended matter on the surface of the flocculated water body, thereby improving the water quality.

[0041] like Figure 3 and Figure 5 As shown, the upper end surfaces of the inclined plate 1 54 and the inclined plate 2 56 are both herringbone-shaped, which reduces the accumulation of sediment scraped off the partition 1 53 and the partition 2 55 and helps the sediment fall into the sedimentation tank 3.

[0042] like Figure 3 and Figure 4 As shown, the sidewall of the sedimentation tank 3 is provided with a plurality of water outlet holes 34 at the outlet end 32, and a water outlet trough 35 is provided below the water outlet holes 34. Water flowing out from the gap between the inclined plate 2 56 and the partition 2 55 flows through the water outlet holes 34 into the water outlet trough 35, facilitating its transfer to the next processing step. The linear actuator 59 drives the connecting frame 5 upward, leaving a gap between the lower end surface of the partition 2 55 and the upper end surface of the inclined plate 2 56. At this point, the water outlet holes 34 are located near the two-thirds position from the lower end to the upper end of the partition 2 55, and the water level inside the sedimentation tank 3 is also close to this position.

[0043] like Figure 3 and Figure 4As shown, a water baffle 58 capable of blocking the water outlet 34 is slidingly provided in the sedimentation tank 3. The linear actuator 59 drives the connecting frame 5 to slide up and down, thereby driving the water baffle 58 to slide up and down, so that the water baffle 58 opens or closes the water outlet 34. Specifically, a guide groove 582 is provided in the upper and lower directions of the side wall of the sedimentation tank 3. A guide member 581 capable of sliding in the guide groove 582 is connected below the water baffle 58. The guide member 581 is in the shape of a rod. A bending groove 584 is provided on the upper part of the connecting frame 5. The bending groove 584 is bent at a right angle and includes a vertical section and a horizontal section. A second slide bar 583 capable of sliding in the horizontal section of the bending groove 584 is provided on the upper part of the baffle 57. The second slide bar 583 is perpendicular to the guide member 581.

[0044] like Figure 4 and Figure 8 As shown, a sewage outlet 36 is opened on the side wall of the sedimentation tank 3 adjacent to the water outlet 34. The height of the sewage outlet 36 is greater than the height of the water outlet 34. After the connecting frame 5 drives the water baffle 58 to descend, the water baffle 58 blocks the water outlet 34, and the water level in the sedimentation tank 3 rises, so that the suspended matter on the water surface can be discharged through the sewage outlet 36.

[0045] like Figure 8 As shown, a screw 6 is provided above the connecting frame 5, and a screw slider 61 is provided on the screw 6. A push plate 62 is fixedly connected to the screw slider 61, which can push the suspended matter on the water surface toward the side close to the sewage outlet 36. A driving motor 63 that can drive the screw 6 to rotate is installed on one side of the sedimentation tank 3.

[0046] like Figure 8 As shown, guide rods 64 parallel to the lead screw 6 are provided on both sides of the lead screw 6 , guide blocks 65 are slidably mounted on the guide rods 64 , and the guide blocks 65 are fixedly connected to the push plate 62 .

[0047] like Figure 4 and Figure 8 As shown, after the linear drive 59 drives the connecting frame 5 to descend, the water baffle 58 blocks the water outlet 34, the water level in the sedimentation tank 3 rises, and the drive motor 63 is started. The drive motor 63 drives the screw 6 to rotate, so that the screw slider 61 drives the push plate 62 to move. The push plate 62 pushes the suspended matter on the water surface to the sewage outlet 36 and discharges it through the sewage outlet 36, which helps to improve the water quality.

[0048] A method for using an energy-saving industrial circulating water treatment device comprises the following steps: Step 1: Add circulating water and reagents into the reaction tank 1 11 and the reaction tank 2 12, start the stirring mechanism 2, and the stirring frame 1 21 and the stirring frame 2 22 stir and mix the circulating water and the reagent respectively. The solenoid valve 41 on the delivery pipe 4 controls the reaction tank 1 11 and the reaction tank 2 12 to alternately supply water to the sedimentation tank 3; Step 2: After the water in the delivery pipe 4 reaches the water distribution tank 42, it reaches the sedimentation tank 3 through multiple water outlets 43, and passes through the gap between two adjacent partition plates 53 and the gap between two adjacent inclined plates 54 in sequence. Then, after passing through the baffle 57, it passes through the gap between two adjacent inclined plates 56 in sequence, and the gap between the inclined plate 56 and the partition plate 55 in sequence, and flows into the water outlet trough 35 through the water outlet hole 34, so as to be transferred to the next treatment process. Step 3: When it is necessary to clean the partition 1 53, the inclined plate 1 54, the partition 2 55 and the inclined plate 2 56, the linear actuator 59 drives the connecting frame 5 to move downward, and the connecting frame 5 drives the partition 1 53 and the partition 2 55 to move downward, so that the partition 1 53 is inserted into the gap between the two adjacent inclined plates 1 54, and the inclined plate 1 54 is inserted into the gap between the two adjacent partition 1 53. The partition 1 53 can scrape off the sediment on the surface of the inclined plate 1 54, and the inclined plate 1 54 can scrape off the sediment on the surface of the partition 1 53. Similarly, the partition 2 55 is inserted into the gap between the two adjacent inclined plates 2 56, and the inclined plate 2 56 is inserted into the gap between the two adjacent partition 2 55. The partition 2 55 can scrape off the sediment on the surface of the inclined plate 2 56, and the inclined plate 2 56 can scrape off the sediment on the surface of the partition 2 55. Step 4: After the linear drive 59 drives the connecting frame 5 to descend, the water baffle 58 blocks the water outlet 34, the water level in the sedimentation tank 3 rises, and the drive motor 63 is started. The drive motor 63 drives the screw 6 to rotate, so that the screw slider 61 drives the push plate 62 to move. The push plate 62 pushes the suspended matter on the water surface to the sewage outlet 36 and discharges it through the sewage outlet 36. The sediment under the sedimentation tank 3 is discharged through the sewage pipe 33.
