Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, specifically to an urban sewage sedimentation and separation device. Background Technology

[0002] Urban wastewater treatment refers to measures taken to change the nature of wastewater so that it does not harm the environment or water bodies. Urban wastewater treatment is generally divided into three levels:

[0003] Primary treatment involves using physical methods to remove insoluble pollutants and parasite eggs from wastewater.

[0004] Secondary treatment involves using biological methods to oxidize and degrade various complex organic substances in the wastewater.

[0005] Tertiary treatment involves using chemical precipitation, biochemical methods, and physicochemical methods to remove phosphorus, nitrogen, recalcitrant organic matter, and inorganic salts from wastewater.

[0006] In the tertiary treatment process, sedimentation tanks are water purification devices that use sedimentation to remove suspended solids from water. Their principle is to utilize the natural sedimentation or coagulation sedimentation of water to remove suspended solids. Sedimentation tanks are classified into horizontal sedimentation tanks and vertical sedimentation tanks according to the water flow direction. Horizontal sedimentation tanks typically have multiple sedimentation chambers (usually three) arranged sequentially along the horizontal direction to achieve multi-stage filtration and sedimentation. However, the sediment inside these chambers needs to be removed using independent cleaning equipment. To simplify this part of the structure, a municipal wastewater sedimentation and separation device is provided. Utility Model Content

[0007] The purpose of this utility model is to provide an urban sewage sedimentation and separation device in order to solve the problems mentioned above.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a municipal sewage sedimentation separation device, comprising a device body and a separation component. The device body consists of a circular sedimentation separation box, a central column, a fixed support, an inlet, and an outlet. The central column is fixed to the middle of the inner side of the circular sedimentation separation box and protrudes to the top of the circular sedimentation separation box. The fixed support is fixed to the outer side of the circular sedimentation separation box and is fixedly connected to the top of the central column. The inlet and outlet are located on the top of the circular sedimentation separation box and are distributed sequentially along the circumference. The separation component is located inside the circular sedimentation separation box.

[0009] As a further embodiment of this utility model: the separating component includes a rotating cylinder, a separating plate, an upper intercepting plate, and a lower intercepting plate;

[0010] The rotating cylinder is rotatably sleeved on the outside of the central column. There is one partition plate and multiple upper and lower interceptor plates. The multiple upper and lower interceptor plates and partition plates are evenly distributed and fixed on the outside of the rotating cylinder along the circumferential direction, and the upper and lower interceptor plates are staggered along the circumferential direction. The partition plate is distributed between the inlet and outlet. The partition plate, upper and lower interceptor plates are used to divide the inner cavity of the circular sedimentation separation tank into a "W"-shaped channel distributed along the circumferential direction, so as to achieve the effect of multiple downward flow and sedimentation of sewage.

[0011] The top of the fixed support and the top of the rotating cylinder are provided with cleaning drive components. The cleaning drive components drive the separation components to rotate and operate, so as to realize the cleaning operation of the sediment at the bottom of the inner wall of the circular sedimentation separation tank.

[0012] As a further embodiment of this utility model: the cleaning drive assembly includes a drive motor, a drive gear, and a driven gear ring;

[0013] The drive motor is mounted on the top of the fixed bracket, and the output end of the drive motor passes through the bottom of the drive motor and is fixedly connected to the drive gear. The driven gear ring is fixed to the top of the outer side of the rotating cylinder and meshes with the drive gear.

[0014] The bottom of the central column is provided with a through hole, and the bottom of the circular sedimentation separation box is fixed with a sewage pipe. The through hole passes through the bottom of the circular sedimentation separation box and is connected to the sewage pipe.

[0015] The outer bottom of the central column is provided with a first sewage outlet, which is connected to the through hole. The outer bottom of the rotating cylinder is provided with a second sewage outlet.

[0016] The drive motor drives the entire separation assembly to rotate via the active gear and the driven gear ring, thereby rotating the second sewage outlet to align with the first sewage outlet, thus enabling the discharge of sewage containing sediment from the inside of the circular sedimentation separation tank.

[0017] As a further embodiment of this utility model: the number of the first sewage outlet and the number of the second sewage outlet are multiple and the same, and when the separating component is in the initial position, the multiple second sewage outlets and the multiple first sewage outlets are staggered along the circumferential direction.

[0018] As a further embodiment of this utility model: the top horizontal height of the partition plate and the upper interceptor plate is flush with the top horizontal height of the circular settling separation box; the bottom horizontal height of the partition plate and the lower interceptor plate is flush with the bottom horizontal height of the inner wall of the circular settling separation box; and the outer sides of the partition plate, the upper interceptor plate, and the lower interceptor plate are in contact with the inner wall side of the circular settling separation box.

[0019] As a further embodiment of this utility model: the bottom horizontal height of the upper interceptor plate is higher than the bottom horizontal height of the inner wall of the circular settling separation box, and the top horizontal height of the lower interceptor plate is lower than the top horizontal height of the circular settling separation box;

[0020] The bottom of the inner wall of the inlet is at a higher horizontal level than the top of the first sewage outlet, while the bottom of the inner wall of the outlet is at a lower horizontal level than the top of the first sewage outlet.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By setting up a separation component, the wastewater flows in a "W"-shaped trajectory between the lower and upper interceptor plates, which slows down the flow speed of the wastewater. The suspended solids in the wastewater can settle to the bottom of the inner wall of the circular sedimentation separation tank. Through the cooperation of multiple sets of lower and upper interceptor plates, a multi-stage sedimentation separation effect can be achieved. Then, the separation component is driven to rotate by the cleaning drive component, which scrapes the sediment inside the circular sedimentation separation tank and mixes it with the wastewater. Finally, it is discharged through the second and first sewage outlets, realizing an efficient cleaning operation of the sediment inside the circular sedimentation separation tank.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4 In this embodiment of the present invention, a municipal sewage sedimentation and separation device includes a main body 1 and a separation component 2. The main body 1 is composed of a circular sedimentation separation box 101, a central column 102, a fixed bracket 106, an inlet 107, and an outlet 108. The central column 102 is fixed to the middle of the inner side of the circular sedimentation separation box 101 and protrudes to the top of the circular sedimentation separation box 101. The fixed bracket 106 is fixed to the outer side of the circular sedimentation separation box 101 and is fixedly connected to the top of the central column 102. The inlet 107 and the outlet 108 are opened on the top of the circular sedimentation separation box 101 and are distributed sequentially along the circumference.

[0030] The separating component 2 includes a rotating cylindrical column 201, a separating plate 202, an upper intercepting plate 203, and a lower intercepting plate 204. The rotating cylindrical column 201 is rotatably sleeved on the outside of the central column 102. There is one separating plate 202, and multiple upper intercepting plates 203 and lower intercepting plates 204 are provided. The multiple upper intercepting plates 203 and lower intercepting plates 204 and the separating plate 202 are evenly distributed and fixed on the outside of the rotating cylindrical column 201 along the circumferential direction, and the upper intercepting plates 203 and lower intercepting plates 204 are staggered along the circumferential direction. The separating plate 202 is distributed between the inlet 107 and the outlet 108. The separating plate 202, the upper intercepting plate 203, and the lower intercepting plate 204 are used to divide the inner cavity of the circular sedimentation separation box 101 into a "W"-shaped channel distributed along the circumferential direction, so as to achieve the effect of multiple downward flow and sedimentation of sewage.

[0031] A cleaning drive assembly 3 is provided on the top of the fixed bracket 106 and the top of the rotating cylinder 201. The cleaning drive assembly 3 drives the separating assembly 2 to rotate, thereby cleaning the sediment at the bottom of the inner wall of the circular sedimentation separation tank 101. The cleaning drive assembly 3 includes a drive motor 301, a drive gear 302, and a driven gear ring 303. The drive motor 301 is mounted on the top of the fixed bracket 106. The output end of the drive motor 301 passes through the bottom of the drive motor 301 and is fixedly connected to the drive gear 302. The driven gear ring 303 is fixed to the top of the outer side of the rotating cylinder 201 and meshes with the drive gear 302. A through hole 10 is provided at the bottom of the central column 102. 3. A sewage pipe 105 is fixed at the bottom of the circular sedimentation separation box 101. A through hole 103 passes through the bottom of the circular sedimentation separation box 101 and is connected to the sewage pipe 105. A first sewage outlet 104 is opened at the bottom outer side of the central column 102. The first sewage outlet 104 is connected to the through hole 103. A second sewage outlet 205 is opened at the bottom outer side of the rotating cylinder 201. The drive motor 301 drives the separation component 2 to rotate as a whole through the drive gear 302 and the driven gear ring 303, so as to make the second sewage outlet 205 rotate to align with the first sewage outlet 104, thereby realizing the discharge of sewage mixed with sediment inside the circular sedimentation separation box 101.

[0032] The top horizontal height of the partition plate 202 and the upper interceptor plate 203 is flush with the top horizontal height of the circular settling separation box 101. The bottom horizontal height of the partition plate 202 and the lower interceptor plate 204 is flush with the bottom horizontal height of the inner wall of the circular settling separation box 101. The outer sides of the partition plate 202, the upper interceptor plate 203 and the lower interceptor plate 204 are in contact with the inner side of the circular settling separation box 101.

[0033] In this embodiment, it should be noted that the sewage inlet pipe is connected to the inlet 107, and the clean water drainage pipe is connected to the outlet 108.

[0034] The operating principle of wastewater sedimentation and separation is as follows:

[0035] First, position the separator component 2 in its initial position (e.g., Figure 1 , 2At this point, the separator 202 is located between the inlet 107 and the outlet 108. The wastewater to be treated by sedimentation is then transported from the inlet 107 to the inside of the circular sedimentation separation tank 101. Subsequently, the wastewater will flow along the gap between the bottom of the upper interceptor plate 203 and the bottom of the inner wall of the circular sedimentation separation tank 101, and along the trajectory of the top of the lower interceptor plate 204. The flow of the wastewater between the lower interceptor plate 204 and the upper interceptor plate 203 forms a "W" shaped trajectory, and the overall trajectory is a circular trajectory. Finally, the wastewater with suspended solids removed flows to the outlet 108 for discharge. During this process, the "W" shaped trajectory of the wastewater flowing between the lower interceptor plate 204 and the upper interceptor plate 203 can slow down the flow speed of the wastewater, and the suspended solids in the wastewater can settle to the bottom of the inner wall of the circular sedimentation separation tank 101. Through the cooperation of multiple sets of lower interceptor plates 204 and upper interceptor plates 203, the effect of multi-stage sedimentation separation can be achieved.

[0036] When it is necessary to clean the sediment inside the separator 101, the procedure is as follows:

[0037] First, close the sewage inlet pipe and the clean water outlet pipe. Then, start the drive motor 301. The drive motor 301 drives the driven gear ring 303 to rotate via the drive gear 302. The driven gear ring 303 drives the rotating cylinder 201 to rotate. The rotating cylinder 201 drives the partition plate 202, the upper interceptor plate 203, and the lower interceptor plate 204 to rotate circumferentially. At this time, the partition plate 202 and the lower interceptor plate 204 can scrape the bottom of the inner wall of the circular sedimentation separation tank 101. The side of the interceptor plate 204 scrapes the inner wall of the circular sedimentation separation tank 101, causing the sediment to be scraped and mixed with the sewage inside the circular sedimentation separation tank 101. At the same time, during the rotation of the rotating cylinder 201, the second sewage outlet 205 on the rotating cylinder 201 will be aligned with the first sewage outlet 104. At this time, the sewage mixed with sediment can be discharged through the channel formed by the second sewage outlet 205, the first sewage outlet 104, the through hole 103, and the sewage pipe 105.

[0038] After the separator component 2 rotates for a certain period of time, allowing the sediment inside the circular sedimentation separation tank 101 to be fully mixed with the sewage, the drive motor 301 can be stopped, and the blocking component 2 can be positioned so that the second sewage outlet 205 is aligned with the first sewage outlet 104. This allows the sewage mixed with sediment to be discharged quickly, thereby cleaning the sediment inside the circular sedimentation separation tank 101. After the cleaning operation is completed, the drive motor 301 is restarted to return the separator component 2 to its initial position, and a secondary sewage sedimentation separation operation can be performed.

[0039] Please refer to this carefully. Figures 1-4The number of first sewage outlets 104 and second sewage outlets 205 is multiple and the number is the same. When the separator component 2 is in the initial position, the multiple second sewage outlets 205 and the multiple first sewage outlets 104 are staggered along the circumferential direction.

[0040] In this embodiment, it should be noted that at least one second sewage outlet 205 is distributed between two adjacent lower interceptor plates 203 and between the lower interceptor plate 203 and the partition plate 202, so as to ensure that sewage is fully discharged during cleaning; by setting multiple first sewage outlets 104 and second sewage outlets 205, efficient sewage discharge operation can be achieved.

[0041] When the separator 2 is in its initial position, the multiple second sewage outlets 205 and the multiple first sewage outlets 104 are staggered along the circumferential direction, which can achieve mutual cut-off between the second sewage outlets 205 and the first sewage outlets 104, thereby ensuring the normal sedimentation and separation operation of sewage.

[0042] Please refer to this carefully. Figures 1-4 The bottom horizontal height of the upper interceptor plate 203 is higher than the bottom horizontal height of the inner wall of the circular settling separation box 101, and the top horizontal height of the lower interceptor plate 204 is lower than the top horizontal height of the circular settling separation box 101.

[0043] The bottom of the inner wall of the inlet 107 is at a higher level than the top of the first sewage outlet 104, and the bottom of the inner wall of the outlet 108 is at a lower level than the top of the first sewage outlet 104.

[0044] In this embodiment, this structure allows sewage to flow smoothly from the inlet 107 to the outlet 108 along a set trajectory.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
