Description

Technical Field

[0001] The invention relates to the technical field of wastewater sedimentation tanks, in particular to a wastewater sedimentation tank with a monitoring mechanism. Background Art

[0002] With the acceleration of industrialization, the problem of wastewater treatment has become increasingly prominent. If the impurities and harmful substances in the wastewater are directly discharged without effective treatment, it will cause serious pollution to the environment. Therefore, it is particularly important to develop an efficient and intelligent wastewater treatment equipment. The wastewater sedimentation tank is mainly used to remove suspended matter and particulate matter in the water so that the water reaches a certain purification level. Based on the effect of gravity, when the wastewater flows into the tank, it is designed to flow as slowly as possible through the flow route. In a static state, the suspended matter in the water will settle to the bottom of the tank under the action of gravity due to its high density, thereby achieving the purpose of water purification. The present invention adds filtering and monitoring functions on the premise of traditional vertical flow sedimentation, and performs secondary filtration and utilization on the wastewater discharged by the device. While saving water resources, the device can also be self-cleaned to prevent the device from being blocked by impurities. Summary of the invention

[0013] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0014] 1. The wastewater sedimentation box with a monitoring mechanism rotates the rotating table in the threaded rod. The rotating table cooperates with the threaded rod sleeve. The rotating table moves up and down on the bottom column through the rotation of the rotating table. The rotating table drives the threaded column fixedly connected to the rotating table to move downward, drives the receiving column connected to the threaded column to descend, and drives the filter plate connected to the receiving column to descend. When the filter plate descends, the water column containing impurities stored in the first shell is elongated. At this time, the rotating table is rotated in the opposite direction, and the threaded column connected to the rotating table begins to rise. The rise of the threaded column drives the rise of the receiving column, and the fixed cylinder connected to the receiving column rises. The filter plate rises with the rise of the square plate, and the water column containing impurities in the first shell is squeezed. The squeezed water column generates pressure on the filter plate. Part of the water containing impurities passes through the filter plate under the action of pressure. The water containing impurities in the first shell is compressed during the above movement to achieve secondary filtration, thereby further improving the water quality of the water penetrating into the water purifier.

[0015] 2. In the wastewater sedimentation box with a monitoring mechanism, when the threaded column is lifted or lowered, the receiving column connected to the threaded column also performs a lifting movement. When the receiving column performs a lifting movement, it drives the lifting movement of the lifting mechanism connected to the receiving column, that is, the filter plate in the lifting mechanism also performs a lifting movement. The lifting movement of the filter plate drives the lifting movement of the second fixed bolt connected thereto. Ball B will rotate when the second fixed bolt rises. The rotation of ball B drives the rotation of the rotating column. The rotation of the rotating column drives the rotation of ball A on the first fixed bolt, completing the eccentric rotation of the rotating rod, thereby driving the rotation of the hexagonal turntable connected to the first fixed bolt. A scraping arc plate is fixedly connected to the end of the hexagonal turntable. The scraping arc plate is thin on both sides and thick in the middle. When the hexagonal turntable rotates, it drives the scraping arc plate to rotate. The shape characteristics of the scraping arc plate are used to scrape the inner wall of the second shell to prevent impurities from adhering to the second shell and affecting the discharge of impurities in the second shell.

[0016] 3. This type of wastewater sedimentation tank with a monitoring mechanism begins to emerge through the overflow of the wastewater in the main core tube from the bottom of the main core tube, and emerges through the other port of the main core tube. The emerging wastewater begins to move in a beam from top to bottom and flows to the bottom of the casing. A baffle is provided at the bottom of the casing. After the water flow hits the baffle, it diverges to all sides. The speed of the water flow is slowed down during the divergence process, and the effect of precipitating impurities is achieved by utilizing the specific gravity of large particles of impurities in the wastewater.

[0017] 4. In this wastewater sedimentation tank with a monitoring mechanism, large particles of impurities are gathered at the conical bottom of the vertical flow pipe. These impurities reach the second water outlet from the bottom of the vertical flow pipe. The second water outlet is connected to the filtering device. Part of the water mixed with the impurities flows through the hole A on the first sleeve to the impurity filter. The lifting mechanism on the impurity filter has a filtering function. The impurities and the water mixed with them are filtered by the lifting mechanism to obtain clean water again. The waste water is reused through secondary filtration, which reduces the waste of water resources.

[0018] 5. This wastewater sedimentation tank with a monitoring mechanism has a scraping arc plate designed to be thin on both sides and thick in the middle, and the scraping arc plate is connected to the hexagonal turntable. The rotation of the turntable is used to squeeze and filter the wastewater while driving the rotation of the hexagonal turntable. The rotation of the hexagonal turntable drives the rotation of the scraping arc plate connected to the hexagonal turntable. The inner wall of the hole D is scraped by the rotation of the scraping arc plate, so as to avoid the phenomenon that impurities are attached to the inner wall of the hole D and are difficult to be discharged after long-term use.

[0048] Working principle:

[0049] In the first step, when the wastewater in the wastewater tank 1 needs to be discharged, the first water valve 12 on the wastewater tank 1 is opened, and the wastewater flows from the first water valve 12 to the main core tube 21 on the vertical flow sedimentation mechanism 2, and emerges from one end port of the main core tube 21 through the main core tube 21. The wastewater in the main core tube 21 begins to overflow from the bottom of the main core tube 21 and emerges through the other end of the main core tube 21. The emerging wastewater begins to move in a beam from top to bottom and flows to the bottom of the sleeve 27. A baffle is provided at the bottom of the sleeve 27. After the water flow hits the baffle, it diverges to the surroundings. The speed of the water flow is slowed down during the divergence process. Large particles of impurities in the wastewater are precipitated to the conical bottom of the vertical flow tube 23 due to specific gravity. The clean water obtained by the vertical flow movement flows over the overflow weir 25 and emerges from the first water outlet 26.

[0050] In the second step, the large particles of impurities contained in the first step are gathered at the conical bottom of the vertical flow pipe 23. When too much impurities are accumulated, they need to be discharged. These impurities reach the second water outlet 28 from the bottom of the vertical flow pipe 23. The second water outlet 28 is connected to the filtering device 31. Part of the water mixed with the impurities flows through the hole A3112 on the first sleeve 311 to the impurity filter 312. The lifting mechanism 3125 on the impurity filter 312 has a filtering function. The impurities and the water mixed with them are filtered by the lifting mechanism 3125 to obtain clean water again. The filtered clean water seeps from the back of the lifting mechanism 3125 into the water purifier 313. The water purifier 313 is externally connected to a monitor 35. The water quality of the clean water in the water purifier 313 is monitored by the monitor 35. When the water quality is qualified, the third water valve 33 is opened, and the clean water collected in the water purifier 313 flows out from the third water valve 33.

[0051] The third step, when the monitor 35 indicates that the water quality is unqualified, the rotating table 015 in the threaded rod 3133 is rotated, and the rotating table 015 cooperates with the threaded rod sleeve 014. The rotating table 015 is rotated to complete the up and down movement of the rotating table 015 on the bottom column 3134. When the water quality is unqualified, the rotating table 015 is rotated to drive the threaded column 013 fixedly connected to the rotating table 015 to move downward, and the threaded column 013 is fixedly connected with the receiving column 012, and the receiving column 012 is fixedly connected with the fixed cylinder 010, and the fixed cylinder 010 is fixedly connected with the square plate 09. The square plate 09 is fixed to the back of the ring 07 through the connecting piece 08, and the ring 07 is connected with the filter plate 011. When the threaded column 013 descends, the receiving column 012 connected to the threaded column 013 is driven to descend, and the filter plate 011 connected to the receiving column 012 is driven to descend. When the rotary table 015 descends, the water column containing impurities stored in the first shell 3111 is stretched. At this time, the rotating table 015 is rotated in the opposite direction, and the threaded column 013 connected to the rotating table 015 begins to rise. The rise of the threaded column 013 drives the rise of the receiving column 012, and the fixed cylinder 010 connected to the receiving column 012 rises, driving the rise of the square plate 09 connected to the fixed cylinder 010. The square plate 09 is connected with a filter plate 011, and the filter plate 011 rises with the rise of the square plate 09, squeezing the water column containing impurities in the first shell 3111. The squeezed water column generates pressure on the filter plate 011, and part of the water containing impurities passes through the filter plate 011 under the action of pressure. The water containing impurities in the first shell 3111 is compressed during the above movement to achieve secondary filtration, thereby further improving the water quality of the water penetrating into the water purifier 313.

[0052] The fourth step, in the third step, when the threaded column 013 is lifted and lowered, the receiving column 012 connected to the threaded column 013 also performs a lifting movement. When the receiving column 012 performs a lifting movement, it drives the lifting and lowering movement of the lifting mechanism 3125 connected to the receiving column 012, that is, the filter plate 011 in the lifting mechanism 3125 also performs a lifting and lowering movement. The front of the filter plate 011 is connected to the second fixing bolt 06, and the second fixing bolt 06 is movably connected to the ball B053. The ball B053 is fixedly connected to the rotating column 052, and the rotating column 052 is fixedly connected to the ball A051. When the filter plate 011 performs a lifting and lowering movement, it drives the lifting and lowering movement of the second fixing bolt 06 connected thereto. The ball B053 will rotate when the second fixing bolt 06 rises. The rotation of the ball B053 drives the rotation of the rotating column 052. The rotation of the rotating column 052 drives the ball A051 on the first fixing bolt 04 The second fixing bolt 06 is connected to a position of the filter plate 011 away from the center of the circle, and the first fixing bolt 04 is connected to a position on the hexagonal turntable 03 away from the center. The eccentric rotation of the rotating rod 05 is completed through the coordination of the positions. The first fixing bolt 04 is also fixedly connected to the hexagonal turntable 03. The rotation of the rotating rod 05 drives the first fixing bolt 04 to rotate, thereby driving the rotation of the hexagonal turntable 03 connected to the first fixing bolt 04. The end of the hexagonal turntable 03 is fixedly connected to a scraping arc plate 02. The scraping arc plate 02 is thin on both sides and thick in the middle. When the hexagonal turntable 03 rotates, the scraping arc plate 02 is driven to rotate. The shape characteristics of the scraping arc plate 02 are used to scrape the inner wall of the second shell 3121 to prevent impurities from adhering to the second shell 3121 and affecting the discharge of impurities in the second shell 3121. At this time, the second water valve 32 is opened to discharge the impurities in the second shell 3121.

[0053] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
