Description

Technical Field

[0001] This application relates to the technical field of building construction engineering, and particularly relates to a pipeline sewage separation device. Background Art

[0002] In building construction, sewage pipes are usually installed during construction for sewage discharge, and the sewage pipes are connected to the municipal sewage system. During use, domestic sewage and the like first flow into the sewage pipes, and then are discharged into the municipal sewage system under the action of hydrodynamic force.

[0003] Currently, when sewage is discharged, since there is a certain distance from the sewage pipes in the community to the municipal sewage system, when the slope of the sewage pipes is insufficient or there are more sundries in the sewage, the hydrodynamic force during sewage discharge is not sufficient to drive the sundries to move to the municipal sewage system; as the usage time increases, the sundries deposited in the pipes accumulate more and more, which may block the pipes, directly affecting the use and lifespan of the pipes. Summary of the Invention

[0004] In order to reduce the possibility of pipeline blockage during sewage discharge, this application provides a pipeline sewage separation device.

[0005] This application provides a pipeline sewage separation device, adopting the following technical solutions:

[0006] A pipeline sewage separation device includes a separation box, a filtration chamber and a collection chamber are formed in the separation box, a sewage inlet pipe and a sewage outlet pipe communicating with the collection chamber are connected to the separation box, and the sewage outlet pipe is located below the sewage inlet pipe;

[0007] A collection port communicating the collection chamber and the filtration chamber is formed in the separation box, the separation box is provided with a guiding plate for guiding sundries entering from the sewage inlet pipe to the collection port, the guiding plate is located between the sewage inlet pipe and the sewage outlet pipe, and a plurality of water filtering holes are formed on the guiding plate;

[0008] A collection box for collecting sundries entering from the collection port is arranged in the separation box, the collection box is located in the collection chamber, and the separation box is provided with a pick-and-place port for picking and placing the collection box.

[0009] By adopting the above technical solutions, domestic sewage enters the filtration chamber from the sewage inlet pipe, and then after being filtered through the water filtering holes on the guiding plate, the sundries in the sewage slide down along the guiding plate into the collection port, and then enter the collection box in the collection chamber from the collection port, while the filtered sewage is discharged through the sewage outlet pipe. When the sewage is discharged, the sundries in the sewage are greatly reduced, which is beneficial to reducing the possibility of pipeline blockage during pipeline sewage discharge in cases where the pipeline slope is insufficient and the hydrodynamic force is insufficient.

[0010] Optionally, the guiding plate is inclined. The guiding plate includes a blank part and a filtering part. The water filtering holes are located in the filtering part, and the blank part is located at a position close to the top of the guiding plate and faces the sewage inlet pipe directly.

[0011] By adopting the above technical solution, the sewage first impacts the blank part, reducing the possibility of sundries jamming the water filtering holes when impacting the guiding plate.

[0012] Optionally, a blocking plate that can be turned over up and down is hinged to the separation box. The blocking plate is located in the filtering cavity and above the guiding plate. A support column that slides horizontally along the separation box is located directly below the blocking plate. When the top of the support column abuts against the top of the blocking plate, the blocking plate blocks the filtering cavity. When the blocking plate blocks the filtering cavity, a water storage space for storing sewage is formed; a floating block located in the water storage space is arranged to slide up and down on the separation box. The separation box is provided with a control component. When the floating block floats close to the sewage inlet pipe, the control component controls the support column to move away from the blocking plate. When the floating block moves away from the sewage inlet pipe, the control component controls the support column to push the blocking plate to turn over and block the filtering cavity.

[0013] By adopting the above technical solution, the sewage is first stored in the water storage space. When the sewage impacts the guiding plate instantaneously, the sewage can drive the sundries filtered by the guiding plate to move towards the collection port, reducing the possibility of the sundries staying on the guiding plate and thus blocking the water filtering holes.

[0014] Optionally, the control component includes a control rope and a control spring. The control rope slidably passes through the separation box. One end of the control rope is connected to the floating block, and the other end is connected to the support column. The control spring is sleeved on the outer peripheral side of the control rope. When the control spring is released, it pushes the support column towards the blocking plate.

[0015] By adopting the above technical solution, as the water level of the sewage rises, it drives the floating block to move upward. At this time, the control rope pulls the support column away from the blocking plate. When the support column separates from the blocking plate, the blocking plate turns downward, which is beneficial to instantaneously discharging the sewage in the water storage space.

[0016] Optionally, the collection box includes a box bottom and a box wall. The box wall surrounds to form a collection space. The box bottom slides up and down in the collection space and is in sliding contact with the box wall. An installation block for the blocking plate to be hinged is arranged to slide up and down on the separation box. The support column slides in the installation block; the separation box is provided with an elastic driving member for driving the installation block close to the sewage inlet pipe. The separation box is provided with a driving component. When the installation block moves away from the sewage inlet pipe, the driving component drives the box bottom to move upward.

[0017] By adopting the above technical solution, when the bottom of the box rises, the sewage level in the water collection space rises, enabling the precipitated sewage to be discharged from the water collection space.

[0018] Optionally, the driving assembly includes a driving column and a driving plate. A hinge shaft is rotatably connected in the separation box. The driving plate is arranged on the outer peripheral side of the hinge shaft. A transmission column is arranged on the top of the driving plate. The transmission column is located directly below the bottom of the box. The driving column slides up and down in the separation box and is arranged at the bottom of the mounting block. A driving rack is arranged on the side wall of the driving column. A driving gear is arranged on the outer peripheral side of the hinge shaft. The driving gear meshes with the driving rack.

[0019] By adopting the above technical solution, when the mounting block moves downward, the driving rack drives the hinge shaft to rotate, causing the transmission column to push the bottom of the box upward, which is beneficial to raising the sewage level in the water collection space.

[0020] Optionally, the elastic driving member is a driving spring. The separation box is provided with a mounting groove for the mounting block to slide up and down. The mounting groove is located on the peripheral side wall of the collection cavity. The driving spring is installed in the mounting groove. The top of the driving spring abuts against the bottom of the mounting block, and the bottom of the driving spring abuts against the bottom wall of the mounting groove.

[0021] By adopting the above technical solution, the driving elastic structure is simple and convenient to use.

[0022] Optionally, the separation box is provided with a support block located in the collection cavity and used for supporting the box wall. The bottom of the box wall and the bottom wall of the collection cavity form a water collection space. The separation box is provided with a transmission hole for transmitting the water flow in the water collection space to the filtration cavity. A plurality of water permeable holes are opened on the peripheral side of the box wall and near the top position. A guiding groove for guiding the filtered water flow from the water permeable holes to the water collection space is opened on the outer peripheral side of the box wall.

[0023] By adopting the above technical solution, the sewage can be discharged from the water collection space through the water permeable holes. At this time, when the sewage in the water collection space is discharged, the water level does not need to rise to the position of the water filtration holes on the guiding plate, which can more conveniently reduce the precipitated sewage in the water collection space. And when discharging, the sewage has passed through precipitation, reducing the possibility of the water permeable holes being blocked.

[0024] In summary, the present application includes at least one of the following beneficial effects:

[0025] 1. During the sewage discharge process, the sewage first passes through the separation box, and the guiding plate in the separation box filters the sewage. When the sewage is discharged through the sewage pipe, the number of sundries is greatly reduced, which is beneficial to reducing the possibility of the pipeline being blocked;

[0026] 2. The blocking plate blocks the filtering cavity to form a water storage space for storing sewage, enabling the sewage to be stored until a certain amount and then instantaneously discharged from the water storage space and filtered by the guiding plate. When the sewage flow rate entering through the sewage inlet pipe is small, sundries are likely to stay on the guiding plate due to the small sewage flow rate and insufficient impact force, increasing the possibility of the sundries blocking the water filtering holes. When the sewage in the water storage space instantaneously impacts the guiding plate, the large sewage volume and sufficient impact force can promptly drive the sundries away from the guiding plate, and the large impact of the sewage can impact the water filtering holes, reducing the possibility of the water filtering holes being blocked.

Detailed Embodiment

[0037] The following will further elaborate on this application Figures 1 - 9 in conjunction with the attached drawings.

[0038] The embodiment of this application discloses a pipeline sewage separation device.

[0039] Embodiment 1

[0040] Refer to Figure 1 , the pipeline sewage separation device includes a separation tank 1, and the separation tank 1 is of a cuboid structure.

[0041] Refer to Figure 2 , a filtering cavity 2 is opened in the middle of the separation tank 1, and a guide plate 14 is obliquely fixed to the separation tank 1. The guide plate 14 is located inside the filtering cavity 2. There are two guide plates 14 and they are symmetrically arranged. One end between the two guide plates 14 is fixedly connected to each other, and forms an inverted "V" - shaped structure. The guide plate 14 includes a filtering part 143 and a blank part 142. The blank part 142 is located at the position of the guide plate 14 close to the top. Water filter holes 141 are opened on the guide plate 14, and the water filter holes 141 are located in the filtering part 143. In other embodiments, the guide plate 14 can also be made into a triangular pyramid structure, where the apex part of the guide plate 14 faces the sewage discharge pipe 12, and the blank part 142 is located at the apex position of the guide plate 14.

[0042] A sewage inlet pipe 11 is fixedly connected to the top of the separation box 1. The sewage inlet pipe 11 is communicated with the filtering chamber 2 and is used for introducing sewage. The sewage inlet pipe 11 is facing the blank part 142. After the sewage enters the filtering chamber 2, it first impacts on the blank part 142, then flows along the blank part 142 towards the filtering part 143. Then, under the action of gravity, the sewage passes through the water filtering holes 141, while the sundries in the sewage are filtered and slide down along the guiding plate 14. At the same time, during the filtering process, the sewage first impacts on the blank part 142. At this time, the sundries in the sewage impact on the blank part 142, reducing the possibility that when the sewage directly impacts on the filtering part 143, the sundries in the sewage are stuck in the water filtering holes 141 under the action of gravity, inertia force, etc., thus causing the blockage of the water filtering holes 141.

[0043] A sewage discharge pipe 12 is fixedly connected to the bottom of the separation box 1. The sewage discharge pipe 12 is connected to the collection chamber 3. The sewage discharge pipe 12 is located below the guiding plate 14. One side of the sewage discharge pipe 12 away from the separation box 1 is communicated with the municipal sewage system. The sewage filtered through the water filtering holes 141 is discharged through the sewage discharge pipe 12. The content of sundries in the sewage discharged through the sewage discharge pipe 12 is greatly reduced. Therefore, during the transmission of the sewage to the municipal sewage system, the possibility of pipeline blockage is greatly reduced.

[0044] Two collection chambers 3 are symmetrically arranged in the separation box 1. The filtering chamber 2 is located between the two collection chambers 3. A collection box 4 is movably arranged in the separation box 1. The collection box 4 is located in the collection chamber 3, and the top end face of the collection box 4 is located below one end of the bottom of the guiding plate 14.

[0045] The separation box 1 is provided with collection ports 13. The collection ports 13 correspond to the collection chambers 3 one by one and are used for communicating the collection chambers 3 and the filtering chamber 2. The collection ports 13 are located above the collection box 4. The sundries sliding down along the guiding plate 14 enter the collection chamber 3 through the collection ports 13, and then fall into the collection box 4, which is collected by the collection box 4.

[0046] A taking and placing port 15 is arranged at the top of the separation box 1. The collection box 4 can be taken out or put into the collection chamber 3 from the taking and placing port 15, which is convenient for replacing the collection box 4. A closing plate 16 is hinged to the separation box 1 for closing the taking and placing port 15. The closing plate 16 can be detachably and fixedly connected to the separation box 1 through connecting pieces such as bolts and screws.

[0047] The implementation principle of a pipeline sewage separation device in an embodiment of the present application is as follows:

[0048] Sewage enters the filtration chamber 2 through the sewage inlet pipe 11. Then, the sewage impacts on the blank part 142, and then flows along the guiding plate 14 towards the collection port 13. During the flowing process, the sewage is filtered by the guiding plate 14 and discharged from the sewage discharge pipe 12, greatly reducing the possibility of blockage in the pipeline. And sundries enter the collection chamber 3 through the collection port 13 and finally fall into the collection box 4. When a certain amount of sundries are collected in the collection box 4, the closing plate 16 can be opened, and then the collection box 4 can be taken out from the access port 15 for unified cleaning.

[0049] Embodiment 2

[0050] See Figure 3 With Figure 4 In this application, the difference between Embodiment 2 and Embodiment 1 is that: the separation box 1 is hinged with a blocking plate 5 that can be turned up and down. The blocking plate 5 is located directly above the guiding plate 14. By temporarily blocking the filtration chamber 2 with the blocking plate 5, a water storage space 21 is formed. The sewage in the sewage inlet pipe 11 enters the filtration chamber 2 and is first stored in the water storage space 21.

[0051] The separation box 1 is symmetrically provided with two receiving grooves 19 for receiving the blocking plate 5. The receiving grooves 19 are located on the opposite side walls of the filtration chamber 2. Connecting shafts are respectively fixed on the opposite sides of the blocking plate 5, and the connecting shafts are rotatably connected to the groove walls of the receiving grooves 19. When the blocking plate 5 is turned to the vertical state, the blocking plate 5 is located in the receiving groove 19, and the vertical side walls on both sides of the blocking plate 5 are respectively in sliding contact with the filtration chamber 2 and the groove walls of the receiving groove 19. One end of the two blocking plates 5 away from the receiving groove 19 is a rounded structure and a rubber layer is fixedly connected to the outer peripheral side. When the two blocking plates 5 are simultaneously turned to the horizontal state, the rubber layers between the two blocking plates 5 are in mutual contact, and the top of the blocking plate 5 abuts against the top groove wall of the receiving groove 19, reducing the size of the gap for sewage leakage.

[0052] The separation box 1 is provided with a support groove 191 extending in the horizontal direction. The support groove 191 is communicated with the receiving groove 19 and the groove opening is located on the groove wall of the receiving groove 19 opposite to the groove opening. The separation box 1 is provided with a support column 6. The support column 6 slides in the receiving groove 19. When the support column 6 slides out of the receiving groove 19, the support column 6 pushes the blocking plate 5 to slide upwards until the blocking plate 5 is turned to the horizontal state. At this time, the top of the support column 6 abuts against the bottom of the blocking plate 5. At the same time, the support column 6 supports the blocking plate 5. When sewage enters the water storage space 21, the gravity received by the blocking plate 5 is transmitted to the support column 6. At this time, the support column 6 restricts the blocking plate 5 from turning downwards, which is beneficial to maintaining the state of the blocking plate 5 blocking the filtration chamber 2.

[0053] The separation box 1 is provided with floating blocks 22. There are two floating blocks 22, which correspond to the support columns 6 one by one. The floating blocks 22 slide up and down on the opposite side walls of the filtering cavity 2 and are located above the blocking plate 5. The separation box 1 is provided with a moving groove 25 extending along the vertical direction. The floating block 22 includes a moving block 221 with an integrally formed "T" - shaped structure. The moving block 221 slides up and down in the moving groove 25 to guide the sliding trajectory of the floating block 22.

[0054] The separation box 1 is provided with a control assembly 7. The control assembly 7 includes a control rope 71 and a control spring 72. The control ropes 71 correspond to the support columns 6 one by one, and the control ropes 71 slide through the separation box 1. One end of the control rope 71 is fixed to the bottom of the moving block 221, and the other end is fixed to the end of the support column 6. The control spring 72 is sleeved on the outer peripheral side of the control rope 71. The control spring 72 is located in the support groove 191. One end of the control spring 72 abuts against the support column 6, and the other end abuts against the groove wall on the side away from the notch of the support groove 191. When the sewage level in the water storage space 21 rises, the floating block 22 moves upward. At this time, the control rope 71 pulls the support column 6 into the support groove 191. When the floating block 22 rises to a certain height, the control rope 71 pulls the support column 6 away from the blocking plate 5. Under the action of gravity, the two blocking plates 5 instantaneously turn downward at the same time, so that the water stored in the water storage space 21 instantaneously impacts on the guiding plate 14. At this time, the large amount of sewage can wash the sundries filtered by the guiding plate 14 into the collection cavity 3, reducing the possibility that the amount of sewage entering through the sewage inlet pipe 11 is small, resulting in the gradual accumulation and blockage of sundries in the water filtering holes 141.

[0055] The sewage stored in the water storage space 21 can be discharged in a short time. After the sewage is discharged, the floating block 22 moves downward. At this time, the control spring 72 elastically releases, pushing the support column 6 out of the support groove 191 and pushing the blocking plate 5 to turn upward.

[0056] Embodiment III

[0057] See Figure 5 , the difference between Embodiment III of the present application and Embodiment II is that: the collection box 4 is composed of a box wall 42 and a box bottom 41.

[0058] See Figure 5 And Figure 6 , the box wall 42 surrounds in a circumferential direction to form a collection space 43. The box bottom 41 slides up and down in the collection space 43, and the box bottom 41 is in sliding contact with the box wall 42 up and down. A plurality of sliding grooves 423 extending along the vertical direction are provided on the inner wall of the circumferential side of the box wall 42. A sliding block 411 is fixedly connected to the side wall of the box bottom 41. The sliding blocks 411 correspond to the sliding grooves 423 one by one and the sliding blocks 411 slide up and down in the sliding grooves 423, so that the box bottom 41 slides in the vertical direction and reduces the possibility of the box bottom 41 detaching from the collection space 43.

[0059] SeeFigure 7 , the separation box 1 is fixedly connected with a plurality of support blocks 18. The support blocks 18 are located in the collection chamber 3 and are respectively fixed on the bottom chamber wall of the collection chamber 3. The bottom of the box wall 42 abuts against the support blocks 18, so that a water collection space 32 is formed between the bottom of the box wall 42 and the bottom of the collection chamber 3. A plurality of water permeable holes 421 are formed in the peripheral side wall of the box wall 42 near the top. The sewage flowing into the collection chamber 3 along the guiding plate 14 is collected in the collection space 43. When the water level of the sewage in the collection space 43 reaches the position of the water permeable holes 421, the sewage is discharged through the water permeable holes 421. A plurality of guiding grooves 422 extending in the vertical direction are formed in the outer peripheral side wall of the box wall 42. One side notch at the bottom of the guiding groove 422 communicates with the water collection space 32, and the water permeable holes 421 are communicated with the guiding grooves 422. The sewage flowing into the guiding grooves 422 from the water permeable holes 421 flows into the water collection space 32 along the guiding grooves 422.

[0060] See Figure 6 and Figure 7 , the separation box 1 is symmetrically provided with transmission holes 33. The two transmission holes 33 respectively communicate the filtration chamber 2 with the two water collection spaces 32, and one side orifice of the transmission hole 33 is located near the bottom of the water collection space 32. After the sewage is collected in the water collection space 32, it flows into the filtration chamber 2 through the transmission holes 33.

[0061] See Figure 7 and Figure 8 , the separation box 1 includes two symmetrically arranged mounting blocks 17. The mounting blocks 17 correspond to the plugging plates 5 one by one and slide up and down in the filtration chamber 2. The separation box 1 is symmetrically provided with two mounting grooves 24 extending in the vertical direction. The mounting blocks 17 slide up and down in the mounting grooves 24, and the accommodating groove 19 and the support groove 191 are respectively formed in the mounting blocks 17. The separation box 1 is provided with an elastic driving member. The elastic driving member is a driving spring 23. The driving springs 23 correspond to the mounting blocks 17 one by one and are installed in the mounting grooves 24. The top of the driving spring 23 abuts against the bottom of the mounting block 17, and the bottom of the driving spring 23 abuts against the bottom of the mounting groove 24. During use, the driving spring 23 elastically releases and pushes the mounting block 17 to slide upward until it abuts against the top wall of the mounting groove 24.

[0062] The separation box 1 is provided with a driving assembly. When the amount of sewage stored in the water storage space 21 increases, the mounting block 17 begins to slide downward and compress the driving spring 23. At this time, the driving assembly drives the bottom of the box 41 to move upward. At this time, the water level in the collection space 43 rises, and the sundries in the collection space 43 settle on the bottom of the box 41 under the action of gravity, while the upper layer of the settled sewage is discharged through the water permeable holes 421; when the mounting block 17 moves upward, the bottom of the box 41 moves downward. At this time, the space for storing sundries and sewage in the collection space 43 increases, reducing the possibility that the collection space 43 overflows and the subsequent incoming sundries and sewage overflow from the collection port 13.

[0063] Refer to Figure 6 and Figure 7 , the driving assembly includes a driving column 8 and a driving plate 82. A hinged groove 34 is formed in the separation box 1. The hinged groove 34 corresponds to and communicates with the water collection space 32 one by one. The separation box 1 is rotatably connected with a hinge shaft 31, and the hinge shaft 31 is located in the hinged groove 34. The driving plate 82 is fixed on the outer peripheral side of the hinge shaft 31. When the hinge shaft 31 rotates, the driving plate 82 moves up and down.

[0064] Refer to Figure 7 and Figure 9 , the driving column 8 is fixed at the bottom position of the mounting block 17 and slides up and down in the separation box 1, and the driving column 8 is perpendicular to the hinge shaft 31 and is located near the end of the hinge shaft 31. A driving rack 81 is fixedly connected to the side wall of the driving column 8. The driving rack 81 is slidably connected with the separation box 1. A driving gear 311 is fixedly connected to the outer peripheral side of the hinge shaft 31. The driving gear 311 meshes with the driving rack 81. When the mounting block 17 moves downward, the driving rack 81 drives the hinge shaft 31 to rotate through the driving gear 311. At this time, the driving plate 82 flips upward.

[0065] Refer to Figure 6 and Figure 7 , one end of the driving plate 82 away from the hinge shaft 31 extends to directly below the bottom of the box 41, and a transmission column 821 facing the bottom of the box 41 is fixedly connected to the top of the driving plate 82. When the driving plate 82 flips upward, the transmission column 821 abuts against the bottom of the box 41 and pushes the bottom of the box 41 to slide upward, so as to achieve the purpose of raising the water level of the sewage in the collection space 43.

[0066] The implementation principle of a pipeline sewage separation device in the third embodiment of this application is as follows:

[0067] In the initial state, the mounting block 17 abuts against the top wall of the mounting groove 24. At this time, the blocking plate 5 blocks the filtering chamber 2, and meanwhile, the sewage in the collection space 43 starts to precipitate, and the control rope 71 is in a slack state. When the sewage enters the water storage space 21 from the sewage inlet pipe 11, the mounting block 17 slides downward, driving the hinge shaft 31 to rotate, so that the driving plate 82 flips to push the bottom of the box 41 upward. At this time, the water level of the sewage in the collection space 43 rises, and the precipitated sewage drains out from the water permeable holes 421. When the mounting block 17 descends, the volume of the water storage space 21 continuously increases until the mounting block 17 slides downward to be close to the bottom wall of the mounting groove 24 and stops. At this time, the sewage entering from the sewage discharge pipe 12 continuously fills the water storage space 21, and the floating block 22 moves upward, driving the support column 6 away from the blocking plate 5. Until the support column 6 disengages from the blocking plate 5, the blocking plate 5 instantly flips downward, so that the sewage in the water storage space 21 is discharged. After the blocking plate 5 flips downward, the downward force borne by the mounting block 17 decreases. At this time, the driving spring 23 pushes the mounting block 17 upward, causing the hinge shaft 31 to move in the reverse direction, and the bottom of the box 41 moves downward under its own gravity and the gravity of the sewage. The filtered debris and the sewage flowing along the guiding plate 14 enter the collection space 43. When the sewage in the water storage space 21 is discharged and the floating block 22 moves downward, the control spring 72 pushes the support column 6 to move, so that the support column 6 pushes the blocking plate 5 to flip to the horizontal state, and then the above process is repeated continuously.

[0068] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
