Description

Technical Field

[0001] The present invention relates to the technical field of water quality environment monitoring, in particular to a sewage biological treatment sampling device. Background Art

[0002] The biological treatment unit is the core component of wastewater treatment and primarily consists of aerobic, anoxic, and anaerobic tanks. Activated sludge and suspended fillers are present within the biological treatment unit, as are some biological tanks coupled with MBBR processes. The status of the activated sludge and microorganisms attached to the fillers within the tanks significantly impacts the wastewater treatment performance of the biological tanks. Therefore, sampling and testing the activated sludge and fillers within the biological treatment unit is crucial for its stable operation.

[0003] Currently, during operational sampling at sewage treatment plants, managers almost exclusively use skimmers or traditional sewage samplers. However, these devices rely on manual operation, resulting in a limited sampling range and limited sampling coverage. They can only sample the edges of the tank, leaving the center and bottom areas inaccessible. However, biological treatment tanks are large, and conditions vary across different areas and depths. Sampling and testing only at the edges of the tank does not accurately reflect the overall operational status of the tank.

[0004] Therefore, it is necessary to propose a sewage biological treatment sampling device to solve at least one of the above problems. Summary of the Invention

[0055] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0056] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an element centered thereon. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an element centered thereon. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementations.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are intended only to describe specific embodiments and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0058] Some patents on water treatment samplers are also disclosed in the prior art, but the specific shortcomings of the prior art are as follows:

[0059] (1) Most biological sewage treatment ponds are large in area. To meet the requirement of covering the entire pond surface, the longitudinal beams across the sewage treatment pond must be long. Existing patents mostly use a single-sided support device to cantilever the longitudinal beams. Due to the influence of the support structure, the longitudinal beam length is limited and the structural stability is relatively low. This cannot meet the sampling requirements of sewage treatment biological ponds with larger widths.

[0060] (2) The existing patent uses a hose plus water pump to collect samples, and moves the pipe water inlet to the sampling point to achieve the effect of fixed-point sampling. Since the sewage treatment biological pool is large, the required hose is long, and the water stored in the hose cannot be ignored. The water stored in the hose will cause the samples collected at different points to mix, thereby affecting the sampling accuracy; and the sampling hose plus water pump method can only collect water samples, and cannot collect samples of activated sludge and fillers in MBBR processes.

[0061] The present invention provides a sewage biological treatment sampling device, which can very conveniently, reliably and accurately sample different positions and depth areas of a biological treatment pool.

[0062] Please refer to the comprehensive Figures 1 to 2In the embodiment of the present application, a sewage biological treatment sampling device is provided, which is used in a sewage treatment tank. The sewage biological treatment sampling device may include: a crossbeam 2, which is relatively arranged at two opposite edges along the side of the sewage treatment tank; a longitudinal beam 16, a first guide mechanism is formed between the longitudinal beam 16 and the crossbeam 2, and under the guiding action of the first guide mechanism, the longitudinal beam 16 can move along the length direction of the crossbeam 2; a sampling unit 18, a second guide mechanism is formed between the sampling unit 18 and the longitudinal beam 16, and under the guiding action of the second guide mechanism, the sampling unit 18 can move along the length direction of the longitudinal beam 16; a sampling bucket 19, the sampling bucket 19 can move with the sampling unit 18 and the sampling bucket 19 can move up and down along the height direction.

[0063] The sewage biological treatment sampling device provided in the embodiment of the present application is provided with a crossbeam 2 spanning both sides of the sewage treatment tank, a longitudinal beam 16 that can move relative to the crossbeam 2, a sampling unit 18 that can move relative to the longitudinal beam 16, and a sampling bucket 19 that can move horizontally with the sampling unit 18 and can move up and down itself. When in use, the sampling unit 18 and the components thereon can be moved to any position in the sewage treatment tank by moving the longitudinal beam 16 and the sampling unit 18 on the longitudinal beam 16. By sending the sampling bucket 19 to the required depth, the sampling bucket 19 is lifted out of the water after the sampling is completed, and the sampling unit 18 is subsequently moved to the edge of the sewage treatment tank, so that the management personnel can take away the salvaged samples. Sample collection at any position and any depth in the sewage treatment tank can be realized, and it is easy to use.

[0064] The present application will be described in detail below with reference to specific drawings and implementation methods.

[0065] The sewage biological treatment sampling device mainly includes: a crossbeam 2 , a longitudinal beam 16 , a sampling unit 18 and a sampling bucket 19 .

[0066] The crossbeam 2 can span across both sides of the sewage treatment tank. The number of crossbeams 2 can be two, though greater than two is not excluded. Compared to the prior art, the longitudinal beams 16 in the embodiment of the present application support the crossbeams 2 on both sides of the sewage treatment tank. This allows for a longer length and greater stability, making the sampling unit 18 less prone to shaking and enabling more accurate and stable sampling point acquisition.

[0067] In one embodiment, a groove (specifically, a U-shaped groove 1) is provided on the upper surface of the crossbeam 2, and a first roller 3 is provided at the lower end of the longitudinal beam 16. The first roller 3 cooperates with the U-shaped groove 1 to form a first guide mechanism.

[0068] In this embodiment, the crossbeam 2 may be a U-shaped beam with an upward opening. The longitudinal beams 16 are provided with first rollers 3 that cooperate with the U-shaped grooves 1 of the crossbeam 2 for guiding movement. The provision of the first rollers 3 on the longitudinal beams 16 can reduce the frictional force that occurs when the longitudinal beams 16 move relative to the crossbeam 2. The number of first rollers 3 can vary depending on the number of longitudinal beams 16. For example, the number of first rollers 3 can be twice the number of longitudinal beams 16, meaning that a first roller 3 can be provided at both ends of each longitudinal beam 16.

[0069] In this embodiment, the longitudinal beam 16 can be moved manually to achieve the movement of the longitudinal beam 16 on the cross beam 2. Of course, a power drive unit can also be provided to drive the longitudinal beam 16 to move relative to the cross beam 2. Drain holes are provided on the bottom of the U-shaped groove 1 of the cross beam 2 to prevent rainwater from accumulating in the U-shaped groove 1.

[0070] In one embodiment, the longitudinal beam 16 is provided with an upwardly opening guide groove 15 , and a second roller 17 is provided at the lower portion of the sampling unit 18 . The second roller 17 cooperates with the guide groove 15 to form the second guide mechanism.

[0071] Specifically, the longitudinal beam 16 is provided with an upwardly opening guide groove 15, and the sampling unit 18 includes a guide portion, such as a second roller 17, that cooperates with the guide groove 15 for guiding movement. When the guide portion of the sampling unit 18 is a second roller 17, the frictional force of the sampling unit 18 relative to the longitudinal beam 16 can be reduced. The number of second rollers 17 can vary depending on the specific configuration of the sampling unit 18; in principle, any number of second rollers 17 is sufficient to ensure that the sampling unit 18 can move relative to the longitudinal beam 16.

[0072] In one embodiment, there may be two longitudinal beams 16 , which are arranged at a predetermined distance along the length direction of the cross beam 2 , and are connected at their ends by a first connecting seat 4 and a second connecting seat 14 .

[0073] In this embodiment, the longitudinal beams 16 may include two longitudinal beams 16, which may be arranged in parallel. One end of the two longitudinal beams 16 may be connected by a first connecting seat 4, and the other end of the two longitudinal beams 16 may be connected by a second connecting seat 14. Specifically, the first connecting seat 4 and the second connecting seat 14 may be fixedly connected to the longitudinal beams 16 or may be integrally formed.

[0074] The first and second connecting bases 4 and 14 connect the two longitudinal beams 16 into a single integrated structure. The sampling unit 18 and sampling hopper 19 can be driven manually or by a power module. When the sampling unit 18 and sampling hopper 19 are driven by a power module, the first and second connecting bases 4 and 14 can also serve as mounting bases for the power modules.

[0075] In one embodiment, the first connecting seat 4 and / or the second connecting seat 14 is provided with a power module, and the sampling unit 18 is connected to the power module and can be driven by the power module to move along the length direction of the longitudinal beam 16 .

[0076] In this embodiment, the power module can be disposed on at least one of the first connecting seat 4 and the second connecting seat 14 . The power module is connected to the sampling unit 18 , thereby being able to drive the sampling unit 18 to move in the opposite direction along the length of the longitudinal beam 16 .

[0077] Specifically, the power module may include: a first drive unit 13 disposed on the second connection base 14, and a first connector 11 connected to the first drive unit 13 and the sampling unit 18. The first drive unit 13 may be a drive motor mounted on the second connection base 14, and the first connector 11 may be a rope connected to the drive motor.

[0078] The power module may further include: a tightening device 5 provided on the first connecting seat 4, a second connecting member 6 connected to the tightening device 5 and the sampling unit 18, and the first connecting member 11 and the second connecting member 6 are both ropes.

[0079] The tightening device 5 may be an automatic elastic tightening device 5 installed on the first connecting seat 4 . The tightening device 5 is connected to the sampling unit 18 via a rope. The tightening device 5 uses elastic contraction to pull the sampling unit 18 to move on the longitudinal beam 16 .

[0080] The sampling unit 18 may include a plate-shaped body, with a first fixed pulley 9 and a second fixed pulley 7 disposed on its upper surface. The first fixed pulley 9 and the second fixed pulley 7 are respectively used to thread the rope. The first fixed pulley 9 may be positioned near the second connecting seat 14, and the direction in which the rope extends between the first fixed pulley 9 and the first drive unit 13 is aligned with the direction in which the longitudinal beam 16 extends. The second fixed pulley 7 may be positioned near the first connecting seat 4, and the direction in which the rope extends between the second fixed pulley 7 and the second drive unit 12 is also aligned with the direction in which the longitudinal beam 16 reflects.

[0081] In some embodiments, an opening is further provided on the plate-like body, the size of the opening being larger than the cross-section of the sampling bucket 19, and the sampling unit 18 further includes a second driving unit 12 for driving the sampling bucket 19 to move up and down, and a third connecting member 10 connected to the second driving unit 12 and the sampling bucket 19.

[0082] In this embodiment, the driving force for driving the sampling bucket 19 to move up and down can be achieved by providing a second driving unit 12. The second driving unit 12 can be in the form of a driving motor.

[0083] Specifically, the plate-like body is further provided with an opening, the size of which is larger than the cross section of the sampling hopper 19 , and the sampling hopper 19 can be lowered into the sampling pool through the opening.

[0084] The plate-like body is provided with a third fixed pulley 8 near the opening. The third connecting member 10 is a rope that is threaded through the third fixed pulley 8. The provision of the third fixed pulley 8 conveniently prevents the rope from contacting the edge of the opening, ensuring that the sampling hopper 19 remains suspended, thereby reducing friction between the rope and the plate-like body.

[0085] In addition, in this embodiment, by installing multiple fixed pulleys on the sampling unit 18, the sampling unit 18 is connected to the driving unit on the longitudinal beam 16 through the fixed pulleys and ropes, so that the components on the movable sampling unit 18 are reduced as much as possible, the weight of the movable sampling unit 18 is reduced, and the load-bearing pressure of the longitudinal beam 16 is reduced.

[0086] The up and down movement of the sampling hopper 19 is controlled by the second drive unit 12. Specifically, the sampling hopper 19 is connected to the second drive unit 12 via a rope. The rope is released and retracted by the second drive unit 12 to control the up and down movement of the sampling hopper 19. After the sampling hopper 19 completes sampling, the sampling unit 18 is controlled to move to the side of the treatment tank, and the operator removes the sampling hopper 19 to complete sampling.

[0087] like Figure 3 As shown, in one embodiment, the sampling hopper 19 may include: a hollow cylinder, an upper cover 20 arranged at the upper end of the cylinder, and a bottom cover 24 arranged at the lower end of the cylinder, the upper cover 20 includes: a top central axis 21 and a first upper cover plate and a second upper cover plate that can rotate around the top central axis 21; the bottom cover 24 includes: a bottom central axis and a first bottom cover plate and a second bottom cover plate that can rotate around the bottom central axis, when the sampling hopper 19 moves downward, the upper cover 20 and the bottom cover 24 open upward; when the sampling hopper 19 moves upward, the upper cover 20 and the bottom cover 24 close.

[0088] In this embodiment, the sampling hopper 19 can be used to collect samples at any depth in any treatment tank. Specifically, the sampling hopper 19 is connected to the rope via the connection portion 22 of the top connection structure 23. The upper cover 20 of the sampling hopper 19 can be composed of two semicircular cover plates (a first upper cover plate and a second upper cover plate), which are fixed by a top central axis 21. The upper cover 20 can rotate 90 degrees at the top around the top central axis 21.

[0089] The upper cover 20 of the sampling hopper 19 may have a circular outline, and the diameter of the circular outline may be close to or slightly larger than the inner diameter of the barrel of the sampling hopper 19. Furthermore, in order to ensure the sealing between the upper cover 20 and the barrel, a sealing gasket is provided on the lower surface of the upper cover 20 or the upper end surface of the barrel. When the first upper cover plate and the second upper cover plate of the upper cover 20 rotate around the top central axis 21 during the downward movement of the sampling hopper 19, the rotation angle range is between 0 degrees and 90 degrees. That is, when the upper cover 20 is in the closed state, the rotation angle of the first upper cover plate and the second upper cover plate is 0 degrees; when the upper cover 20 is in the open state, the rotation angle of the first upper cover plate and the second upper cover plate can be a maximum of 90 degrees, so that the sampling hopper 19 can automatically rotate and reset during its upward movement, automatically switching from the open state to the closed state.

[0090] Furthermore, the bottom cover 24 of the sampling hopper 19 has the same or similar structure as the upper cover 20. The bottom cover 24 can also have a circular outline, with a diameter equal to or similar to the inner diameter of the barrel of the sampling hopper 19. When the bottom cover 24 is open, its first and second bottom cover plates can be rotated into the barrel. Furthermore, to ensure a tight seal between the bottom cover 24 and the barrel, a sealing ring can be provided on the outer periphery of the bottom cover or on the inner surface of the lower end of the barrel.

[0091] When the first and second bottom cover plates of the bottom cover 24 rotate about the bottom central axis during the downward movement of the sampling hopper 19, the rotation angle range is between 0 and 90 degrees. That is, when the bottom cover 24 is in the closed state, the rotation angle of the first and second bottom cover plates is 0 degrees; when the bottom cover 24 is in the open state, the rotation angle of the first and second bottom cover plates can be up to 90 degrees, so that the first and second bottom cover plates can automatically rotate and reset during the upward movement of the sampling hopper 19, automatically switching from the open state to the closed state.

[0092] When the sampling bucket 19 moves downward, affected by the hydraulic force at the bottom, both the upper cover 20 and the bottom cover 24 will open upward, allowing water to quickly pass through the entire cylinder. When the sampling bucket 19 reaches a certain depth, sampling is carried out. The sampling bucket 19 moves upward, tightening the connecting rope. Under the action of the hydraulic force at the top and the gravity of the upper cover 20 and the bottom cover, the upper cover 20 and the bottom cover fall, and the sampling bucket 19 is closed to ensure internal sealing and achieve the effect of fixed-point sampling. Compared with the prior art, the sampling bucket 19 used in the embodiment of the present application does not have the influence of mixing samples collected at different points, and can collect activated sludge, fillers, etc. in the pool.

[0093] Of course, in the embodiments of the present application, it is not excluded to adopt other existing forms of sampling bucket structures to achieve the above-mentioned sampling function.

[0094] The sewage biological treatment sampling device provided in the embodiment of the present application can achieve the effect that the sampling bucket 19 can sample at any position in the biological pool space by controlling the movement of the longitudinal beam 16 on the crossbeam 2, the movement of the sampling unit 18 on the crossbeam 2, and the movement of the sampling bucket 19 in the vertical direction. During the sinking process of the sampling bucket 19, the bottom and top are opened by the action of the water flow, and water enters the bottom of the sampling bucket 19 and flows out from the top. During the upward pulling process, the bottom and top of the sampling bucket 19 are closed under the action of the water pressure to achieve the effect of fixed-point sampling. This sampling device not only reduces the danger of sewage plant operators during the sampling process, but also can achieve the effect of sampling at any point, providing more diverse sample collection possibilities for biological treatment pool sampling and testing.

[0095] It should be noted that, in the description of this application, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be understood to indicate or imply relative importance. Furthermore, in the description of this application, unless otherwise specified, "plurality" means two or more.

[0096] The above-mentioned various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0097] The above are only a few embodiments of the present invention.
