Description

Technical Field

[0001] The present invention belongs to the field of sewage treatment equipment, and more specifically, relates to a multi-track internal inflow non-metallic orifice plate grille sewage cleaner. Background Art

[0002] Pretreatment is an indispensable process flow in the sewage treatment process. Pretreatment mainly intercepts slag and sand in sewage through physical filtration and sedimentation to ensure the stable operation of subsequent processes.

[0003] The slag intercepting equipment in the pretreatment area of a sewage treatment plant is mainly divided into three types according to the bar gap: coarse grille (25 - 100 mm), medium grille (10 - 25 mm), and fine grille (1.5 - 10 mm), which are used to intercept larger solid pollutants in sewage in a suspended or floating state.

[0004] Common fine grille structural forms in sewage treatment plants include rotary rake tooth fine grille, rotary mesh plate fine grille, internal inflow orifice plate fine grille, etc. The internal inflow orifice plate fine grille is divided into internal inflow metal orifice plate grille and internal inflow non-metallic orifice plate grille according to the orifice plate material. The rotary rake tooth fine grille and the rotary mesh plate fine grille are both installed obliquely perpendicular to the water flow direction, and the internal inflow orifice plate grille is installed perpendicular to the water flow direction parallelly. Sewage enters the interior of the grille from the front inlet of the grille, flows out after being filtered by the orifice plates on both sides, and flows to the back of the grille from the water discharge channels on both sides of the grille. The grid residue is intercepted by the mesh plate and removed by fishing.

[0005] The longitudinal direction of the mesh plate of the internal inflow orifice plate grille is parallel to the channel direction. Therefore, the longitudinal length of the mesh plate is not limited by the channel width. Rotary wheels are designed at both ends of the mesh plate to walk and rotate in the guide rail grooves on the end panels of the equipment frame. During the operation of the equipment for filtering sewage, the pressure generated by the liquid level difference inside and outside the mesh plate acts on the mesh plate, and the force is finally applied to the guide rail grooves at both ends by the rotary wheels at both ends of the mesh plate. That is, the overall force type of the mesh plate is a "simply supported beam" structure supported by the guide rails at both ends.

[0006] When the width of the mesh plate is less than 1.8 m and the liquid level difference inside and outside the mesh plate is less than 0.5 m, the mesh plate of this "simply supported beam" type can operate normally by relying solely on the support of the guide rails at both ends, and the mesh plate will not deform. However, when the width of the mesh plate is greater than 1.8 m and the liquid level difference inside and outside the mesh plate is greater than 0.5 m, the force on the mesh plate increases and the mesh plate will undergo "bulging" deformation. The mesh plate and the connecting shaft of the mesh plate will bulge outward and bend only relying on the support of the guide rail grooves at both ends, ultimately resulting in equipment failure and abnormal operation. Summary of the Invention

[0007] The object of the present invention is to provide a multi-track inward-flow non-metallic orifice-plate grille sewage cleaner in view of the deficiencies of the prior art. An intermediate support guide rail is provided in the side support frame of the sewage cleaner. When the sewage cleaner intercepts pollutants in the channel, the water flow causes a great impact on the filter screen structure, so that the middle section of the filter screen structure will be bent and deformed. The intermediate support guide rail will effectively support the filter screen structure to prevent the sewage cleaner from being affected by excessive deformation and affecting normal operation.

[0008] To achieve the above object, the present invention provides a multi-track inward-flow non-metallic orifice-plate grille sewage cleaner, including:

[0009] A support structure, including a lower support frame, an upper support frame, and two mutually parallel side support frames. One end of the support structure is open, and the other end of the support structure is connected by a sealing plate.

[0010] A filter screen structure, which is in a ring structure. The filter screen structure is rotatably arranged between the two side support frames. The filter screen structure includes at least two ring-shaped filter screen components, and the filter screen components are connected by metal chain plates. The intermediate support guide rail is used to support the metal chain plates. Rotary wheels are respectively provided at both ends of the filter screen structure, and the rotary wheels are matched with the guide rail grooves;

[0011] A drive structure, which is drivingly connected to the filter screen structure.

[0012] Optionally, a wear detection sensor is provided on the intermediate support guide rail, and the wear detection sensor monitors the thickness of the intermediate support guide rail.

[0013] Optionally, the wear detection sensor is a metal detector, the probe of the metal detector faces the side of the metal chain plate, and the metal detector is connected to an alarm.

[0014] Optionally, it further includes two flow guide plates, and the flow guide plates are respectively connected to one end of the side support frame.

[0015] Optionally, a frame housing is sleeved outside the upper support frame. The frame housing is horizontally arranged on the bank of the channel, and the drive structure is provided on the frame housing. The drive structure includes a motor reducer, and the output end of the motor reducer extends into the frame housing and is connected to two drive sprockets, and the drive sprockets are respectively engaged with the ends of the filter screen structure.

[0016] Optionally, the filter screen assembly includes multiple rows of filter orifice plates. Each row of the filter orifice plates is arranged horizontally, with a width of 150 mm for each row. The pitch between adjacent two rows of the filter orifice plates is 300 mm. Each row of the filter orifice plates includes a plurality of the filter orifice plates, and a plurality of conical holes are uniformly arranged on the filter orifice plates. The aperture of the conical holes increases along the water flow direction.

[0017] Optionally, mounting shaft holes are respectively formed at two ends of each row of the filter orifice plates. A rotary shaft penetrates through the two mounting shaft holes.

[0021] The present invention provides a multi-track internal flow non-metallic orifice plate grille sewage cleaner, and its beneficial effects are as follows: An intermediate support guide rail is arranged in the middle of the side support frames of the sewage cleaner, and the intermediate support guide rail is arranged opposite to the metal chain plate in the filter screen structure. When the filter screen structure bulges and deforms under the impact of water flow, the metal chain plate is attached to the intermediate support guide rail. In this way, the intermediate support guide rail will reduce the deformation amount of the filter screen. In addition, a metal detector is also arranged on the intermediate support guide rail, which can monitor the wear degree of the metal chain on the intermediate support guide rail at all times.

[0031] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0032] The present invention provides a multi-track internal inflow non-metallic orifice plate grille cleaner, including:

[0033] A support structure, including a lower support frame, an upper support frame, and two mutually parallel side support frames. One end of the support structure is open, and the other end of the support structure is connected by a sealing plate. Guide rail grooves are respectively provided at both ends of the side support frame, and at least one intermediate support guide rail is provided in the middle of the side support frame along the vertical direction;

[0034] The filter screen structure is in a ring structure and is rotatably arranged between two side support frames. The filter screen structure includes at least two ring-shaped filter screen components, which are connected by metal chain plates. The middle support guide rail is used to support the metal chain plates. Rotary wheels are respectively arranged at both ends of the filter screen structure, and the rotary wheels are matched with the guide rail grooves.

[0035] The driving structure is drivingly connected to the filter screen structure.

[0036] Specifically, a support structure is provided in the dirt remover. The support structure includes support frames at the upper and lower ends and side support frames on the side, forming a tubular frame structure. And at one end in the horizontal direction of the tubular frame structure, it is hermetically connected by a sealing plate. The water flow in the channel enters from the open end of the tubular frame structure, then passes through the filter screen structure parallel to the side support frames, and finally flows into the downstream. When the river water passes through the filter screen structure, the filter screen structure is completely bent and deformed. In this way, the middle support guide rail on the support structure effectively supports the middle part of the filter screen structure, avoiding excessive bending and deformation of the filter screen structure, which may cause the dirt remover to malfunction. In addition, the filter screen structure is formed by connecting multiple ring-shaped filter components through metal chain plates. Therefore, when the filter screen structure is bent, the bending deformation amount of the position of the metal chain plate is the largest. In this way, the middle support guide rail fits and supports the metal chain plate, which can reduce the bending deformation amount of the filter screen structure.

[0037] Optionally, a wear detection sensor is arranged on the middle support guide rail, and the wear detection sensor monitors the thickness of the middle support guide rail.

[0038] Specifically, the wear detection sensor is used to monitor the thickness of the middle support guide rail. Due to the impact of the water flow, the filter screen structure is bent and abuts against the middle support guide rail. When the filter screen structure intercepts solid pollutants in the channel, the filter screen structure also needs to be in a rotating state at all times. When the filter screen structure abuts against the middle support guide rail, there will also be a sliding friction movement between the two. Keeping this situation for a long time will cause the thickness of the middle support guide rail to decrease. When the wear detection sensor detects that the guide rail thickness drops to the set value, it will remind the staff to replace the middle support guide rail in time. If the middle support guide rail is not replaced, when the filter screen structure is bent and deformed again by the water flow impact, the middle support guide rail will not be able to effectively support the filter screen structure.

[0039] Optionally, the wear detection sensor is a metal detector. The probe of the metal detector faces the side of the metal chain plate, and the metal detector is connected to an alarm.

[0040] Specifically, when the intermediate support guide rail fits and supports the filter screen structure with filtering deformation, the filter screen structure needs to intercept solid pollutants in the water in the channel. Therefore, the filter screen structure remains in a rotating state, and relative friction will occur between the rotating filter screen structure and the intermediate support guide rail. When the thickness of the intermediate support guide rail exceeds the wear limit value, the metal detector originally hidden in the intermediate support guide rail will be exposed, and the metal detector can identify the metal chain plate, indicating that the wear of the intermediate support guide rail has exceeded the limit. Once the filter screen structure is bent and deformed by the impact of water flow, the intermediate support guide rail will no longer effectively support the filter screen. At this time, the intermediate support guide rail needs to be replaced. When the new intermediate support guide rail is installed, the metal detector will be hidden inside the intermediate support guide rail, and the new intermediate support guide rail can also support and protect the bent and deformed filter screen again to prevent more serious failures caused by abnormal operation of the equipment.

[0041] Optionally, it further includes two diversion plates, and the diversion plates are respectively connected to one end of the side support frame.

[0042] Optionally, a frame housing is sleeved outside the upper support frame. The frame housing is horizontally arranged across the bank of the channel. A driving structure is arranged on the frame housing. The driving structure includes a motor reducer. The output end of the motor reducer extends into the frame housing and is connected to two driving sprockets. The driving sprockets are respectively meshed with the ends of the filter screen structure.

[0043] Optionally, a slag collection trough is further arranged inside the upper support frame, and the slag collection trough is located below the driving sprocket.

[0044] Specifically, a frame housing is arranged on the bank of the channel, and a driving sprocket is arranged inside the frame housing. The output end of the motor reducer extends into the frame housing and is connected to the driving sprocket, so as to drive the driving sprocket to rotate. The filter screen can intercept solid pollutants in the channel, and when the filter screen rotates to the slag collection trough, the solid pollutants on the filter screen are collected into the slag collection trough through the flushing water nozzle.

[0045] Optionally, the filter screen assembly includes multiple rows of filter orifice plates. Each row of filter orifice plates is arranged horizontally. The width of each row of filter orifice plates is 150 mm, and the pitch between adjacent two rows of filter orifice plates is 300 mm. Each row of filter orifice plates includes multiple filter orifice plates, and a plurality of conical holes are uniformly arranged on the filter orifice plates. The aperture of the conical holes increases along the water flow direction.

[0046] Optionally, mounting shaft holes are respectively opened at both ends of each row of filter orifice plates. A rotary shaft penetrates through the two mounting shaft holes. Rotary wheels are arranged at both ends of the rotary shaft, and the rotary wheels are slidably arranged in the guide rail grooves of the side support frame.

[0047] Specifically, the filter screen structure is composed of multiple rows of filter orifice plates. Each row of filter orifice plates is formed by connecting multiple filter orifice plates through metal link plates. When water flows through the filter orifice plates, the conical holes can intercept pollutants. The filter orifice plates are hinged to the rotary shaft, and both ends of the rotary shaft are connected to the guide rail grooves of the side support frames through rotary wheels. The guide rail grooves can limit the moving direction of the rotary wheels. In this way, each row of filter orifice plates is supported and connected to the side support frames through the structures at both ends, forming a "simple supported beam" support form for the filter orifice plates.

[0048] Optionally, the side support frames include multiple connecting cross beams arranged horizontally, and the connecting cross beams are perpendicularly connected to the middle support guide rails.

[0049] Specifically, the side support frames are composed of multiple horizontally arranged connecting cross beams and vertically arranged middle support guide rails. The connecting cross beams and the middle support guide rails form a grid structure. The filtered water can also pass through the side support frames normally. The side support frames can also form a structure with high support strength in the filter screen structure. When the filter screen structure is impacted by water flow, the middle part of the filter screen structure can be supported by the middle support guide rails in a fitting manner, avoiding excessive deformation of the filter screen structure and affecting the normal operation of the dirt remover.

[0050] Optionally, the material of the filter orifice plates is non-metallic polypropylene.

[0051] Specifically, the dirt remover is installed in the channel. Since the filter screen structure of the dirt remover rotates, the lower half of the filter screen structure is below the liquid level of the channel. After the water flow enters the interior of the filter screen structure from the guide plate, since the sealing plate does not allow water to pass through, the water flow can only flow out from both sides of the dirt remover through the filtration of the filter screen structure. The filter screen structure remains in a rotating state in the channel. In this way, the solid pollutants intercepted by the filter screen structure are carried to the channel and collected centrally. When the filter screen structure intercepts the solid pollutants in the water flow, the water flow will also impact the filter screen structure, causing the filter screen structure to bend and deform in the downstream direction. Since a row of filter orifice plates is arranged in the same horizontal direction in the filter screen structure, this row of filter orifice plates is formed by connecting multiple filter orifice plates through metal link plates, and the filter screen structure is only supported and connected to the side support frames at both ends. In this way, the filter screen structure is in a "simple supported beam" structure, and the position where the bending deformation is the most serious is the metal link plate at the central position. Therefore, at least one middle support guide rail is arranged at the central position of the side support frames of the dirt remover. When the filter screen structure does not bend and deform, the gap between the metal link plate and the middle support guide rail is not greater than 1 mm. While ensuring the normal rotation of the filter screen structure, once the filter screen structure bends and deform, it can be supported by the middle support guide rail in a fitting manner, avoiding serious deformation of the filter screen and affecting the normal operation of the dirt remover.

[0052] Optionally, the length of each row of filter orifice plates in the horizontal direction is not less than 1.8 m, and the liquid level difference on both sides of the filter net is greater than 0.5 m.

[0053] Specifically, the width of the filter orifice plate of the dirt remover can be greater than 1.8 m. Due to the support of the intermediate support guide rail, the bent and deformed filter orifice plate can be effectively supported, avoiding the failure shutdown of the dirt remover.

[0054] Embodiment

[0055] As Figures 1 to 5 shown, the present invention provides a multi-track inward-flow non-metallic orifice plate grille dirt remover, including:

[0056] A filter net 1, wound around the output end of a motor reducer 2. The lower half of the filter net 1 is arranged below the liquid level of a channel 10. A side support frame 5 is arranged on one side of the filter net 1 close to the bank 4 of the channel;

[0057] Two guide plates 6, respectively connected to one end of an upward filter net 7 and one end of a downward filter net 8. A sealing plate 9 is arranged between the other end of the upward filter net 7 and the other end of the downward filter net 8. The water flow of the channel 10 enters the inner area of the filter net 1 between the guide plates 6;

[0058] The filter net 1 includes multiple rows of filter orifice plates. The filter orifice plates are arranged horizontally. Each row of filter orifice plates includes a plurality of filter orifice plates 11. Adjacent filter orifice plates 11 are connected by a metal chain plate 12. Two intermediate support guide rails 13 corresponding to the metal chain plate 12 are arranged on the side support frame 5. The gap between the intermediate support guide rail 13 and the metal chain plate 12 is not greater than 1 mm.

[0059] In this embodiment, a metal detector 14 is arranged in the intermediate support guide rail 13. The probe of the metal detector 14 faces the side of the metal chain plate 12. The metal detector 14 is connected to an alarm.

[0060] In this embodiment, the side support frame 5 further includes a plurality of connecting cross beams 15 arranged horizontally. The connecting cross beams 15 are perpendicularly connected to the intermediate support guide rails 13.

[0061] In this embodiment, the width of each row of filter orifice plates 11 is 150 mm, and the pitch between adjacent two rows of filter orifice plates 11 is 300 mm.

[0062] In this embodiment, a plurality of conical holes are uniformly arranged on the filter orifice plate 11. The aperture of the conical holes increases along the water flow direction.

[0063] In this embodiment, mounting shaft holes are respectively formed at both ends of each row of filter orifice plates 11. A rotary shaft 16 is penetrated through the two mounting shaft holes. Rotary wheels 17 are arranged at both ends of the rotary shaft 16, and the rotary wheels 17 are slidably arranged in the guide rail grooves 18 of the side support frames 5.

[0064] In this embodiment, it further includes a frame housing 19. The frame housing 19 is horizontally arranged across the bank 4 of the channel. A driving sprocket 20 connected to the output end of the motor reducer 2 is arranged inside the frame housing 19. The driving sprocket 20 is at both ends of the filter net 1, and the driving sprocket 20 drives the middle filter net to maintain a rotating motion state from both ends.

[0065] In this embodiment, a slag collection tank 21 is further arranged inside the frame housing 19, and the slag collection tank 21 is located below the driving sprocket 20.

[0066] In this embodiment, the material of the filter orifice plate 11 is non-metallic polypropylene.

[0067] In this embodiment, the length of each row of filter orifice plates 11 in the horizontal direction is not less than 1.8 m, and the liquid level difference on both sides of the filter net 1 is greater than 0.5 m.

[0068] In summary, the dirt remover is vertically arranged in the channel 10. The filter net 1 of the dirt remover rotates under the drive of the motor reducer 2. The water flow in the channel 10 flows into the interior of the filter net 1 between the two guide plates 6, and then the solid pollutants in the water flow are intercepted and filtered by the filter net 1, and the water flow flows out from both sides of the dirt remover. The width of the filter net 1 of the dirt remover in the horizontal direction is greater than 1.8 m. When the water flow velocity is large and causes the middle of the filter net 1 to bend and deform, the two middle support guide rails 13 centrally arranged on the side support frame 5 can support the metal chain plates 12 between the filter orifice plates 11, avoiding excessive bending and deformation of the filter net and affecting the normal operation of the dirt remover; in addition, a metal detector 14 is further arranged inside the middle support guide rail 13. When the filter net 1 is impacted by the water flow, the middle of the filter net 1 fits with the middle support guide rail 13, and during the process of the filter net 1 filtering and intercepting the water flow, the filter net 1 maintains a rotating state, which will cause relative sliding friction between the filter net 1 and the middle support guide rail 13. After long-term friction, the thickness of the middle support guide rail 13 is worn. When the thickness of the middle support guide rail 13 is less than the set thickness, the probe of the metal detector 14 is exposed and can identify the middle support guide rail 13, and the metal detector 14 emits an alarm signal. The staff needs to replace the middle support guide rail and other vulnerable parts, and the replaced middle support guide rail 13 can resume effective support for the bent and deformed filter net.

[0069] The embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is also not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
