Description

TECHNICAL FIELD

[0001] The utility model belongs to sewage treatment equipment field, more specifically, relate to a kind of non-metal hole plate grid decontamination machine of multi-track inner flow. BACKGROUND

[0002] Pretreatment is an indispensable process in the sewage treatment process, and is mainly achieved by physical filtration and sedimentation to intercept the sludge and sand in the sewage, so as to ensure the stable operation of the subsequent process.

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

[0004] The common fine grid structure of the sewage treatment plant includes rotary rake tooth fine grid, rotary mesh plate fine grid, and inner flow hole plate fine grid. The inner flow hole plate fine grid is divided into inner flow metal hole plate grid and inner flow non-metal hole plate grid according to the material of the hole plate. The rotary rake tooth fine grid and the rotary mesh plate fine grid are installed vertically to the water flow direction, and the inner flow hole plate grid is installed vertically to the water flow direction. The sewage enters the grid from the water inlet at the front of the grid, flows out after being filtered by the hole plates on both sides, and then flows to the back of the grid through the water outlet channels on both sides. The grid sludge is intercepted by the mesh plate and removed.

[0005] The longitudinal mesh plate of the inner flow hole plate grid is parallel to the channel direction, so the length of the longitudinal mesh plate is not limited by the width of the channel. The two ends of the mesh plate are designed to rotate in the guide groove on the end panel of the equipment frame. During the operation of the equipment in filtering sewage, the pressure generated by the difference in liquid level inside and outside the mesh plate acts on the mesh plate, and the stress is finally transmitted to the guide grooves at both ends by the rotating wheels at both ends of the mesh plate. That is, the overall stress type of the mesh plate is a "simply supported beam" structure supported by the guide grooves at both ends.

[0006] When the width of the mesh plate is less than 1.8 m and the difference in liquid level inside and outside the mesh plate is less than 0.5 m, the mesh plate of the "simply supported beam" type can normally operate by relying on the support of the guide grooves 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 difference in liquid level inside and outside the mesh plate is greater than 0.5 m, the mesh plate will deform due to the increase in stress, and the mesh plate and the connecting shaft will be bent and deformed outwardly, which will eventually cause equipment failure and cannot operate normally.

[0032] Preferred embodiments of the present invention will now be described in more detail. While 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 to the embodiments set forth herein. Rather, 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.

[0033] This utility model provides a multi-track internal flow non-metallic perforated plate bar screen cleaning machine, comprising:

[0034] The support structure includes a lower support frame, an upper support frame, and two 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 provided at both ends of the side support frames, and at least one intermediate support guide rail is provided in the middle of the side support frames along the vertical direction.

[0035] The filter structure is ring-shaped and is rotatably mounted between two side support frames. The filter structure includes at least two ring-shaped filter components, which are connected by metal chain plates. The middle support rail is used to support the metal chain plates. Rotary wheels are provided at both ends of the filter structure, and the rotary wheels cooperate with the guide rail grooves.

[0036] The drive structure is connected to the filter screen structure.

[0037] When the filter structure is in a straight position, the distance between the metal chain plate and the intermediate support rail is no more than 1mm.

[0038] Specifically, the sludge removal machine is equipped with a support structure, which includes upper and lower support frames and side support frames, forming a tubular frame structure. One end of the tubular frame structure is sealed with a sealing plate. Water flows into the channel 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 downstream. When the river passes through the filter screen structure, the filter screen structure is completely bent and deformed. The middle support guide rail on the support structure effectively supports the middle part of the filter screen structure, preventing excessive bending and deformation of the filter screen structure, which would cause the sludge removal machine to malfunction. In addition, the filter structure is formed by connecting multiple ring-shaped filter components via metal chain plates. Therefore, when the filter structure bends, the metal chain plates experience the greatest bending deformation. The intermediate support rail then closely supports the metal chain plates, reducing the amount of bending deformation in the filter structure. When the filter structure is not bending, the gap between the metal chain plates and the intermediate support rail is no more than 1mm. This ensures the normal rotation of the filter structure while providing close support from the intermediate support rail should bending occur, preventing excessive deformation and extending the filter structure's lifespan.

[0039] Optionally, a wear detection sensor is installed on the intermediate support guide rail to monitor the thickness of the intermediate support guide rail.

[0040] Specifically, wear detection sensors monitor the thickness of the intermediate support rail. Due to the impact of water flow, the filter screen structure bends and rests against the intermediate support rail. When the filter screen intercepts solid pollutants in the channel, it needs to be constantly rotating. When the filter screen is against the intermediate support rail, sliding friction occurs. Over time, this reduces the thickness of the intermediate support rail. When the wear detection sensor detects that the rail thickness has dropped to a set value, it alerts staff to replace the intermediate support rail promptly. If the intermediate support rail is not replaced, when the filter screen structure is again impacted and bent by water flow, the intermediate support rail will no longer be able to effectively support the filter screen structure.

[0041] Optionally, the wear detection sensor is a metal detector, with the probe of the metal detector facing one side of the metal chain plate, and the metal detector is connected to the alarm.

[0042] Specifically, when the intermediate support rail supports the deformed filter screen structure, the filter screen structure needs to intercept solid pollutants in the channel water. Therefore, the filter screen structure is in a rotating state. The rotating filter screen structure and the intermediate support rail will generate relative friction. When the thickness of the intermediate support rail exceeds the wear limit, the metal detector that was originally hidden in the intermediate support rail will be exposed. The metal detector can identify the metal chain plate, which means that the wear of the intermediate support rail has exceeded the limit. Once the filter screen structure is bent and deformed by the impact of water flow, the intermediate support rail will no longer provide effective support for the filter screen. At this time, the intermediate support rail needs to be replaced. After the new intermediate support rail is installed, the metal detector is hidden inside the intermediate support rail, and the new intermediate support rail can also support and protect the bent and deformed filter screen again, preventing more serious failures caused by abnormal operation of the equipment.

[0043] Optionally, it also includes two deflectors, each connected to one end of the side support frame.

[0044] Optionally, a frame housing is fitted over the upper support frame, spanning across the bank of the channel. A drive structure is provided on the frame housing, including a motor reducer. The output end of the motor reducer extends into the frame housing and is connected to two drive sprockets, which respectively mesh with the ends of the filter screen structure.

[0045] Optionally, a slag collection trough is also provided inside the upper support frame, and the slag collection trough is located below the drive sprocket.

[0046] Specifically, a frame housing is installed on the bank of the channel, and a drive sprocket is installed inside the frame housing. The output end of the motor reducer extends into the frame housing and connects to the drive sprocket, thus driving the drive sprocket to rotate. The filter screen then intercepts 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 by flushing water nozzles.

[0047] Optionally, the filter assembly includes multiple rows of filter plates, each row of filter plates is arranged horizontally, each row of filter plates is 150mm wide, the pitch between two adjacent rows of filter plates is 300mm, each row of filter plates includes multiple filter plates, and multiple conical holes are evenly arranged on the filter plates, the diameter of the conical holes increases along the water flow direction.

[0048] Optionally, each row of filter plates has mounting shaft holes at both ends, and a rotating shaft is installed through the two mounting shaft holes. Rotating wheels are installed at both ends of the rotating shaft, and the rotating wheels are slidably installed in the guide rail grooves of the side support frame.

[0049] Specifically, the filter structure consists of multiple rows of filter plates, each row of which is formed by connecting multiple filter plates via metal chain plates. When water flows through the filter plates, the conical holes can intercept pollutants. The filter plates are hinged to a rotating shaft, and the two ends of the rotating shaft are connected to the guide rail grooves of the side support frame through rotating wheels. The guide rail grooves can restrict the movement direction of the rotating wheels. In this way, each row of filter plates is supported by the side support frame through the structure at both ends, forming a "simply supported beam" support form for the filter plates.

[0050] Optionally, the side support frame includes multiple horizontally arranged connecting beams, which are perpendicularly connected to the intermediate support guide rail.

[0051] Specifically, the side support frame is composed of multiple horizontally arranged connecting beams and vertically arranged intermediate support rails. The connecting beams and intermediate support rails form a grid structure, allowing filtered water to pass through normally. The side support frame also forms a high-strength support structure for the filter screen. When the filter screen is impacted by water flow, the middle of the filter screen structure can be supported by the intermediate support rails, preventing excessive deformation of the filter screen structure and affecting the normal operation of the cleaning machine.

[0052] Optionally, the filter plate is made of non-metallic polypropylene.

[0053] Specifically, the sludge removal machine is installed in a channel. Because the filter screen structure rotates, the lower half of the filter screen is below the water surface in the channel. After water enters the filter screen structure from the guide plate, the sealing plate prevents water flow. The water can only flow out from both sides of the sludge removal machine through the filter screen structure. The filter screen structure continues to rotate in the channel. In this way, solid pollutants intercepted by the filter screen structure are carried to the channel and collected. While the filter screen structure intercepts solid pollutants in the water flow, the water flow also impacts the filter screen structure, causing it to bend and deform downstream. Since the filter screen structure has a row of filters arranged in the same horizontal direction... The perforated plate, a row of filter plates connected by metal chain plates, has a "simply supported beam" structure with only its two ends connected to the side support frame. The most severe bending deformation occurs at the central metal chain plate. Therefore, the decontamination machine has at least one intermediate support rail in the center of the side support frame. When the filter structure is not bent, the gap between the metal chain plate and the intermediate support rail is no more than 1mm. This ensures the normal rotation of the filter structure while providing close support from the intermediate support rail should the filter structure be bent, preventing severe deformation that could affect the normal operation of the decontamination machine.

[0054] Optionally, the length of each row of filter plates in the horizontal direction shall not be less than 1.8m, and the liquid level difference on both sides of the filter screen shall be greater than 0.5m.

[0055] Specifically, the width of the filter plate of this cleaning machine can be greater than 1.8m. With the support of the intermediate support rail, the filter plate that is bent or deformed can be effectively supported, avoiding the cleaning machine from malfunctioning and shutting down.

[0056] Example

[0057] like Figures 1 to 5 As shown, this utility model provides a multi-track internal flow non-metallic perforated plate bar screen cleaner, comprising:

[0058] The filter screen 1 is wound around the output end of the motor reducer 2. The lower half of the filter screen 1 is set below the liquid surface of the channel 10. A side support frame 5 is provided on the side of the filter screen 1 near the bank 4 of the channel.

[0059] Two guide plates 6 are connected to one end of the upward filter screen 7 and one end of the downward filter screen 8, respectively. A sealing plate 9 is provided between the other end of the upward filter screen 7 and the other end of the downward filter screen 8. The water flow of the channel 10 enters the inner area of ​​the filter screen 1 from between the guide plates 6.

[0060] The filter screen 1 includes multiple rows of filter plates arranged horizontally. Each row of filter plates includes multiple filter plates 11. Adjacent filter plates 11 are connected by metal chain plates 12. The side support frame 5 is provided with two intermediate support rails 13 corresponding to the metal chain plates 12. The gap between the intermediate support rails 13 and the metal chain plates 12 is no more than 1mm.

[0061] In this embodiment, a metal detector 14 is installed inside the intermediate support rail 13. The probe of the metal detector 14 faces the side of the metal chain plate 12, and the metal detector 14 is connected to the alarm.

[0062] In this embodiment, the side support frame 5 also includes a plurality of connecting beams 15 arranged in the horizontal direction, and the connecting beams 15 are perpendicularly connected to the intermediate support rail 13.

[0063] In this embodiment, the width of each row of filter plates 11 is 150mm, and the pitch between two adjacent rows of filter plates 11 is 300mm.

[0064] In this embodiment, a plurality of conical holes are uniformly arranged on the filter plate 11, and the diameter of the conical holes increases along the water flow direction.

[0065] In this embodiment, each row of filter plate 11 has mounting shaft holes at both ends, and a rotating shaft 16 is installed through the two mounting shaft holes. Rotating wheels 17 are installed at both ends of the rotating shaft 16, and the rotating wheels 17 are slidably installed in the guide rail groove 18 of the side support frame 5.

[0066] In this embodiment, a frame housing 19 is also included. The frame housing 19 is horizontally arranged on the bank 4 of the channel. A drive sprocket 20 connected to the output end of the motor reducer 2 is provided inside the frame housing 19. The drive sprocket 20 is located at both ends of the filter screen 1. The drive sprocket 20 drives the filter screen in the middle to maintain a rotating motion from both ends.

[0067] In this embodiment, a slag collection trough 21 is also provided inside the frame housing 19, and the slag collection trough 21 is located below the drive sprocket 20.

[0068] In this embodiment, the filter plate 11 is made of non-metallic polypropylene.

[0069] In this embodiment, the length of each row of filter plates 11 in the horizontal direction is not less than 1.8m, and the liquid level difference on both sides of the filter screen 1 is greater than 0.5m.

[0070] In summary, the sludge removal machine is vertically installed in the channel 10. The filter screen 1 of the sludge removal machine rotates under the drive of the motor reducer 2. Water in the channel 10 flows into the interior of the filter screen 1 between the two guide plates 6, and then the filter screen 1 intercepts and filters solid pollutants in the water flow. The water flows out from both sides of the sludge removal machine. The horizontal width of the filter screen 1 in this sludge removal machine is greater than 1.8m. When the water flow velocity is high and causes the middle of the filter screen 1 to bend and deform, the two intermediate support guide rails 13 centrally located on the side support frame 5 can support the metal chain plates 12 between the filter plates 11, preventing excessive bending and deformation of the filter screen and affecting the normal operation of the sludge removal machine. In addition, a metal probe is also installed inside the intermediate support guide rail 13. When the filter screen 1 is impacted by water flow, the middle part of the filter screen 1 comes into contact with the intermediate support rail 13. During the process of filtering and intercepting the water flow, the filter screen 1 rotates, which causes relative sliding friction between the filter screen 1 and the intermediate support rail 13. After a long period of friction, the thickness of the intermediate support rail 13 wears down. When the thickness of the intermediate support rail 13 is less than the set thickness, the probe of the metal detector 14 is exposed and can identify the intermediate support rail 13. The metal detector 14 issues an alarm signal, and the staff needs to replace the intermediate support rail and other vulnerable parts. Only after the intermediate support rail 13 is replaced can it effectively support the bent and deformed filter screen.

[0071] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
