Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a device for monitoring the content of suspended matter in sewage. Background Art

[0002] Suspended matter in sewage refers to solid particles in the water that cannot pass through the filter membrane (usually with a pore size of 0.45μm), including sediment, organic matter, microorganisms, colloids, etc. For sewage treatment operations, monitoring the suspended matter content is an important indicator for water quality assessment, which directly affects water transparency, dissolved oxygen content and ecosystem health.

[0003] In existing sewage treatment tanks, sewage in the tank is filtered and treated in multiple stages by multi-stage filter elements. The suspended matter content in the sewage between the multi-stage filter elements in the tank is usually monitored by inserting a suspended matter sensor to filter the sewage between the multi-stage filter elements.

[0004] When the existing sewage suspended matter content monitoring device is actually used, the suspended matter sensor is in a static position in the tank. However, it is impossible to change the position to monitor the distribution of suspended matter content in water layers of different depths in the tank, resulting in poor errors in the suspended matter content monitoring data after sewage treatment. Summary of the Invention

[0010] Preferably, the synchronization mechanism includes a mounting frame fixedly mounted on the inner cavity of the frame, and a synchronous pulley is fixedly mounted on each set of the mounting frames.

[0011] Preferably, a synchronous belt is fixedly sleeved between the synchronous pulleys in the same group, and a transmission shaft is fixedly connected through multiple groups of synchronous pulleys located on the same straight line at the bottom of the inner cavity of the frame.

[0012] Preferably, a dual-axis motor is fixedly installed in the middle of the inner cavity of the frame, and the output ends of the dual-axis motor are respectively fixedly connected to the two groups of transmission shaft ends.

[0013] Preferably, a guide plate is fixedly installed on the top of the mounting plate, a guide groove is opened in the middle of the guide plate, a positioning pin is movably inserted inside the guide groove, and a rocker arm is fixedly installed at the center of one side of the synchronous pulley located at the top of the frame cavity, and the rocker arm is hinged to one end of the positioning pin at one end away from the synchronous pulley.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1:

[0029] This embodiment introduces a device for monitoring the content of suspended solids in sewage. Figure 1-Figure 3 As shown, a device for monitoring suspended solids content in sewage includes a treatment tank 1, a frame 2, a filter element 11, and a mounting rod 31. Multiple groups of filter elements 11 are used to grade the sewage in the treatment tank 1. Multiple groups of mounting rods 31 are respectively arranged at equal intervals between adjacent filter elements 11.

[0030] Multiple monitoring mechanisms 3 are evenly spaced on the top of the treatment tank 1, multiple suspended matter sensors are installed outside the mounting rod 31, multiple synchronization mechanisms 4 are installed between the treatment tank 1 and the frame 2, and transmission mechanisms 5 and reciprocating toggle mechanisms 6 are evenly spaced on the top of the inner cavity of the frame 2;

[0031] Among them, the monitoring mechanism 3 includes a mounting plate 30 fixedly mounted on the top of the mounting rod 31, a stirring blade 32 is fixedly mounted near the bottom of the mounting rod 31, and a suspended matter sensor is fixedly mounted on the end of the stirring blade 32. A turntable 33 is rotatably mounted at equal intervals in the middle of the inner cavity of the frame 2. The turntable 62 coaxially connected to the transmission shaft 44 can be driven synchronously. The reversing guide block 63 and the positioning rod 64 on the turntable 62 can contact the corresponding turntable 33 and move the turntable 33. When the two groups of positioning rods 64 and the path groove 332 on the turntable 62 alternately move the turntable 33, the turntable 33 can rotate back and forth periodically.

[0032] Among them, a path groove 332 and a reversing groove 331 are respectively opened on one side and the edge of the outer circumference of the turntable 33. The path groove 332 is an X-shaped structure. When the transmission shaft 44 passes through the transmission turntable 62, the reversing guide block 63 and the positioning rod 64 on the turntable 62 can contact the corresponding turntable 33 and move the turntable 33. When the two sets of positioning rods 64 on the turntable 62 and the path groove 332 alternately move the turntable 33.

[0033] Among them, through grooves are opened at equal intervals on the top of the treatment tank 1, and end covers 12 are fixedly installed on the top of the through grooves. Splines 311 are integrally formed at equal intervals near the top of the outer periphery of the installation rod 31. Spline grooves matching the splines 311 are opened on the top of the end cover 12 and the inner diameter of the turntable 33. The installation rod 31 inserted in the turntable 33 can rotate synchronously with the cooperation of the splines 311, so that the stirring blades 32 at the bottom end of the installation rod 31 can stir the sewage in the corresponding filter element 11 to form a turbulent flow, so that the suspended matter in the sewage becomes dynamic, and the contact surface of the suspended matter sensor is larger.

[0034] Among them, the synchronization mechanism 4 includes a mounting frame 41 fixedly mounted on the inner cavity of the frame 2, and each group of mounting frames 41 is fixedly mounted with a synchronous pulley 42. A synchronous belt 43 is fixedly sleeved between the synchronous pulleys 42 of the same group. A transmission shaft 44 is fixedly connected through multiple groups of synchronous pulleys 42 located on the same straight line at the bottom of the inner cavity of the frame 2. A dual-axis motor 45 is fixedly mounted in the middle of the inner cavity of the frame 2. The output ends of the dual-axis motor 45 are fixedly connected to the ends of the two groups of transmission shafts 44 respectively. The transmission shafts 44 on both sides are driven by the dual-axis motor 45. The synchronous pulleys 42 on the transmission shaft 44 can drive the synchronous pulley 42 at the rocker arm 53 in cooperation with the synchronous belt 43.

[0035] like Figure 3 、 Figure 5 As shown, in this embodiment, sewage enters through the water inlet on one side of the treatment tank 1, and is graded and filtered by the multi-group graded filter elements 11 in the treatment tank 1, so that the content of suspended solids in the sewage between each group of filter elements 1 gradually decreases;

[0036] like Figure 4 、 Figure 5 As shown, in this embodiment, the transmission shafts 44 on both sides are driven by the dual-axis motor 45. The synchronous pulleys 42 on the transmission shafts 44 can drive the corresponding rocker arms 53 on the synchronous pulleys 43 in cooperation with the synchronous belts 43, so that the rocker arms 53 toggle the positioning pins 52 in the guide grooves 510 for periodic up and down reciprocating motions, thereby enabling the guide plates 51 to drive the corresponding mounting plates 30 and the mounting plug rods 31 fixed at the bottom to reciprocate up and down along the spline grooves in the turntable 33. In this way, the suspended matter sensors on the stirring blades 32 at the bottom of the mounting plug rods 31 can monitor the suspended matter at different depths of the sewage in the treatment tank 1, thereby realizing the monitoring of suspended matter in the sewage at different depths in the treatment tank 1.

[0037] Example 2:

[0038] Based on Example 1, this example introduces a device for monitoring the content of suspended solids in sewage. Figure 4-Figure 7 As shown, the transmission mechanism 5 is used to lift and lower the installation rod 31, and the reciprocating mechanism 6 is used to reverse the installation rod 31.

[0039] Among them, a guide plate 51 is fixedly installed on the top of the mounting plate 30, a guide groove 510 is opened in the middle of the guide plate 51, and a positioning pin 52 is movably inserted inside the guide groove 510. A rocker arm 53 is fixedly installed at the center of one side of the synchronous pulley 42 located at the top of the inner cavity of the frame 2. The end of the rocker arm 53 away from the synchronous pulley 42 is hinged to the end of the positioning pin 52, and the dual-axis motor 45 drives the transmission shafts 44 on both sides. The synchronous pulley 42 on the transmission shaft 44 can transmit the rocker arm 53 on the corresponding synchronous pulley 43 with the cooperation of the synchronous belt 43, so that the rocker arm 53 drives the positioning pin 52 in the guide groove 510 to move up and down periodically, so that the guide plate 51 can drive the corresponding mounting plate 30 and the mounting rod 31 fixed at the bottom to move up and down along the spline groove in the turntable 33.

[0040] Among them, the reciprocating toggle mechanism 6 includes a mounting seat 61 fixedly installed in the inner cavity of the frame 2, and a turntable 62 is rotatably installed inside the mounting seat 61. Reversing guide blocks 63 and positioning rods 64 are fixedly installed at equal intervals on the outer circumference of the turntable 62. One end of the positioning rod 64 extends to the inside of the corresponding path groove 332, and the mounting rod 31 extends into the inner cavity of the treatment tank 1. The stirring blades 32 are located between the two groups of corresponding filter elements 11. When the two groups of positioning rods 64 on the turntable 62 and the path groove 332 alternately toggle the turntable 33, the turntable 33 can rotate reciprocally periodically, and the mounting rod 31 inserted in the turntable 33 can rotate synchronously with the cooperation of the spline 311, so that the stirring blades 32 at the bottom end of the mounting rod 31 can stir the sewage in the corresponding filter element 11 to form a turbulent flow, which makes the suspended matter in the sewage dynamic, and makes the contact surface of the suspended matter sensor larger, thereby forming dynamic monitoring of the suspended matter in different water layers between the multi-stage filter elements 11, and the monitoring data is more accurate.

[0041] like Figure 4-Figure 6 As shown, in this embodiment, the turntable 62 coaxially connected to the transmission shaft 44 can be driven synchronously. When the two sets of positioning rods 64 on the turntable 62 enter the path groove 332 and pass through the reversing groove 331, the reversing guide block 63 on the turntable 62 can immediately enter the reversing groove 331 to form a positioning for the turntable 33, so that the turntable 33 can form a reciprocating motion at this position. At this time, the mounting rod 31 can only move up and down through the transmission mechanism 5 and cannot rotate, so that the suspended matter sensor on the stirring blade 32 can monitor the suspended matter at the bottom of the tank body. In this way, while the turntable 33 rotates, the mounting rod 31 inserted inside it can rotate synchronously with the spline 311, so that the stirring blade 32 at the bottom end of the mounting rod 31 can stir the sewage in the corresponding filter element 11 to form a turbulent flow, which makes the suspended matter in the sewage dynamic, so that the contact surface of the suspended matter sensor is larger, thereby forming dynamic monitoring of the suspended matter in different water layers between the multi-stage filter elements 11, and the monitoring data is more accurate.

[0042] Working principle: When in use, sewage enters through the water inlet on one side of the treatment tank 1, and is graded and filtered by the multi-group graded filter element 11 in the treatment tank 1, so that the suspended solids content of the sewage between each group of filter elements 1 gradually decreases, so that the sewage at the water outlet on the other side of the treatment tank 1 can be graded and treated;

[0043] While treating the sewage in the treatment tank 1 and monitoring the sewage between the multi-stage filter elements 11, the transmission shafts 44 on both sides are driven by the dual-axis motor 45. The synchronous pulleys 42 on the transmission shafts 44 cooperate with the synchronous belts 43 to transmit the rocker arms 53 on the corresponding synchronous pulleys 43, so that the rocker arms 53 move the positioning pins 52 in the guide grooves 510 to reciprocate up and down periodically, thereby enabling the guide plates 51 to drive the corresponding mounting plates 30 and the mounting rods 31 fixed at the bottom to reciprocate up and down along the spline grooves in the turntable 33. In this way, the suspended matter sensors on the stirring blades 32 at the bottom of the mounting rods 31 can monitor the suspended matter at different depths of the sewage in the treatment tank 1, thereby realizing the monitoring of suspended matter in the sewage at different depths in the treatment tank 1.

[0044] The turntable 62 coaxially connected to the transmission shaft 44 can be driven synchronously. When the two sets of positioning rods 64 on the turntable 62 enter the path groove 332 and pass through the reversing groove 331, the reversing guide block 63 on the turntable 62 can immediately enter the reversing groove 331 to form a positioning for the turntable 33, so that the turntable 33 can form a reciprocating motion at this position. At this time, the mounting rod 31 can only move up and down through the transmission mechanism 5 and cannot rotate, so that the suspended matter sensor on the stirring blade 32 can monitor the suspended matter at the bottom of the tank body. In this way, the turntable 33 rotates while The mounting rod 31 inserted inside it can rotate synchronously with the cooperation of the spline 311, so that the stirring blade 32 at the bottom end of the mounting rod 31 can stir the sewage in the corresponding filter element 11 to form a turbulent flow, which makes the suspended matter in the sewage dynamic, and makes the contact surface of the suspended matter sensor larger, thereby forming dynamic monitoring of suspended matter in different water layers between the multi-stage filter elements 11, and the monitoring data is more accurate. This makes the suspended matter in the sewage dynamic, and makes the contact surface of the suspended matter sensor larger, thereby forming dynamic monitoring of suspended matter in different water layers between the multi-stage filter elements 11, and the monitoring data is more accurate.
