Description

Technical Field

[0001] This invention relates to the field of wastewater testing technology, and in particular to a device for testing wastewater discharged from buildings. Background Art

[0002] Construction wastewater mostly originates from wastewater generated during production activities at construction sites and factories. It may contain pollutants such as silt, chemicals, and oil, making it difficult to treat. Construction wastewater is usually stored in wastewater storage tanks for centralized treatment.

[0003] Chinese utility model patent with publication number CN214845182U discloses a wastewater testing device for construction, including a box body, a water storage tank fixedly installed at the bottom of the box body, a drain tank fixedly installed on one side of the water storage tank, a support column fixedly installed on one side of the box body, a heat dissipation plate fixedly installed on the side of the box body away from the support column, a test cover fixedly installed on the top of the box body, a printer controller fixedly installed on one side of the test cover, a testing chamber fixedly installed at the bottom of the test cover and inside the box body, and a cleaning nozzle fixedly installed inside the testing chamber.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When construction wastewater is directly added to the testing chamber, because the construction wastewater contains a large number of small particles, these substances are prone to sedimentation and stratification within the testing chamber. When testing the construction wastewater in the testing chamber, it is difficult to ensure the uniformity of the components in the construction wastewater and the accuracy of the test results. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a device for detecting wastewater discharge from buildings.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a building wastewater detection device, comprising a base, a pad fixed to the top of the base, a water storage tank fixed to the upper end of the pad, and an operating platform fixed to the top of the base and located on one side of the water storage tank. A spherical filter screen is arranged near the bottom of the water storage tank, and a stirring blade is arranged on the outside of the spherical filter screen. A driving component for driving the spherical filter screen to rotate is arranged on the base. A mounting frame is fixed on the operating platform, and a transfer box is fixed on the top of the mounting frame. A pumping component for sucking the building wastewater inside the spherical filter screen into the transfer box is arranged on the operating platform. A rotating shaft located below the transfer box is rotatably mounted on the operating platform, and a turntable is fixed to the upper end of the rotating shaft. A rotating component for driving the turntable to rotate is arranged on the operating platform. Multiple sampling components are arranged near the edge of the turntable. A discharge component for discharging the building wastewater inside the transfer box into the sampling components is arranged on the transfer box. A COD detector is also arranged on one side of the turntable on the operating platform.

[0007] By adopting the above technical solution, the spherical filter screen effectively intercepts construction wastewater entering the pumping assembly, preventing large pieces of construction debris from affecting the normal operation of the pumping assembly. The construction wastewater is pumped into the transfer tank by the pumping assembly, and then enters the sampling assembly through the discharge assembly. After one set of sampling assemblies is filled with construction wastewater sample, the rotating assembly drives the turntable to rotate, allowing the spare pumping assembly to be used for sampling. Subsequently, the staff places the sampling assembly into the COD analyzer for wastewater testing. To prevent the stratification caused by particulate matter in the construction wastewater from affecting the accuracy of the wastewater test results, the staff drives the spherical filter screen to rotate by driving the assembly, thereby making the spherical filter screen and the stirring blade rotate synchronously, thus stirring the construction wastewater, improving the uniformity of particulate matter dispersion in the construction wastewater, and ensuring the accuracy of the wastewater test results.

[0008] Furthermore, the pumping assembly includes a pump body fixed to the top of the operating table, a pumping pipe fixed to and connected to the inlet end of the pump body, and an outlet pipe fixed to and connected to the outlet end of the pump body. The end of the outlet pipe away from the pump body passes through the top of the transfer box and extends into the transfer box. The pumping pipe passes through the base, the bottom of the water storage tank, and the bottom of the spherical filter screen in sequence and extends into the spherical filter screen. The axis of the section of the pumping pipe away from the pump body coincides with the axis of the water storage tank, and the center of the spherical filter screen is located on the axis of the water storage tank.

[0009] By adopting the above technical solution, after the pump body is working, it draws construction sewage from the storage tank through the pumping pipe. The sewage is discharged into the transfer box through the outlet pipe. The spherical filter screen plays a good filtering role for the water entering the pumping pipe, reducing the probability of large pieces of construction waste in the sewage clogging the pumping pipe and ensuring the normal operation of the pumping components.

[0010] Furthermore, the drive assembly includes a cover fixed to the bottom wall of the water storage tank and a central shaft that passes through the top of the cover and is rotatably connected to the cover; the cover is a cylindrical cover structure with an open bottom and a hollow interior, the upper end of the central shaft is fixed to the bottom of the spherical filter screen, the central shaft and the top of the cover are sealed by a rotating shaft seal, and the section of the water pump pipe away from the pump body passes through the central shaft and is clearance-fitted; the drive assembly also includes a fan blade fixedly sleeved on the central shaft and located inside the cover, a high-pressure blower fixed to the top of the base, and a blower pipe fixed to and connected to the air outlet of the high-pressure blower, the end of the blower pipe away from the high-pressure blower passes through the base and the bottom of the water storage tank in sequence, and is set towards the edge of the fan blade.

[0011] By adopting the above technical solution, after the high-pressure blower starts working, it blows high-pressure airflow into the enclosure through the air pipe, thereby causing the fan blades to drive the central shaft to rotate. Since the upper end of the central shaft is fixed to the bottom of the spherical filter screen, and the central shaft and the top of the enclosure are kept sealed by a rotating shaft seal, the spherical filter screen and the stirring blades fixed on the spherical filter screen rotate to stir the construction sewage in the water storage tank, promote the uniform dispersion of various components in the construction sewage, and ensure the accuracy of sewage test results.

[0012] Furthermore, an annular block is fixed on the inner bottom wall of the water storage tank. The outer wall of the annular block is in close contact with the inner wall of the water storage tank, the inner wall of the annular block is in close contact with the outer wall of the cover, and the top of the annular block is flush with the top of the cover.

[0013] By adopting the above technical solution, the ring-shaped block design reduces the amount of wastewater inside the water storage tank that is difficult to be drawn out by the pumping pipe.

[0014] Furthermore, the stirring blades are arranged in a spiral around the outer wall of the spherical filter screen, and multiple overflow holes are provided through the stirring blades.

[0015] By adopting the above technical solution, the spiral-shaped stirring blades on the outer wall of the spherical filter can agitate the construction particles at the bottom of the water storage tank, promoting the uniform mixing of construction wastewater in the water storage tank. The overflow hole allows some of the particles carried by the stirring blades to fall back, which is beneficial to improving the mixing effect of various components in the construction wastewater.

[0016] Furthermore, the discharge assembly includes a drain pipe fixed to and connected to the bottom of the transfer box and a solenoid valve disposed on the drain pipe; multiple sets of the sampling assemblies are evenly distributed about the axis of the turntable, each sampling assembly includes a mounting block fixed to the top of the turntable, the top of the mounting block is provided with a mounting groove, the sampling assembly also includes a sampling tube that is inserted into the mounting groove and a funnel that is detachably connected to the upper end of the sampling tube, the distance between the axis of the drain pipe and the axis of the turntable is equal to the distance between the axis of the sampling tube and the axis of the turntable, and the inner diameter of the top of the funnel is greater than the outer diameter of the drain pipe.

[0017] By adopting the above technical solution, after the solenoid valve is opened, the sewage in the transfer box enters the funnel through the drain pipe, and then enters the sampling tube. When the collected construction sewage in the sampling tube reaches the liquid level, the solenoid valve closes. The rotating component then drives the turntable and rotating shaft to rotate, moving the next set of sampling tubes without sewage below the drain pipe. The process of opening the solenoid valve to collect construction sewage is then repeated. The funnel design allows the sampling tube to be opened without being perfectly aligned with the drain pipe to collect sewage.

[0018] Furthermore, the bottom of the transfer box is fixed with multiple cameras located near the drain pipe, and the control panel is fixed with a controller that is electrically connected to both the cameras and the solenoid valve.

[0019] By adopting the above technical solution and setting up the camera, it is convenient for staff to observe the position of the funnel and the liquid level collection in the sampling tube in real time, and transmit the monitoring results to the controller in real time, so that staff can control the operation of the solenoid valve in real time according to the monitoring situation.

[0020] Furthermore, the rotating assembly includes a vertical plate fixed to the top of the operating table, a rotating rod rotatably mounted on the vertical plate, a motor fixed to the vertical plate and used to drive the rotating rod to rotate, a worm gear fixed to the end of the rotating rod away from the vertical plate, and a worm wheel fixedly sleeved on the rotating shaft and meshing with the worm gear.

[0021] By adopting the above technical solution, after the motor works, it drives the rotating rod to rotate, which in turn drives the worm to rotate. This causes the worm wheel meshing with the worm, the rotating shaft fixed to the worm wheel, and the turntable fixed to the upper end of the rotating shaft to rotate, thereby controlling the sampling tube that has not collected sewage to move to the bottom of the drain pipe and to collect sewage.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. In order to prevent the sedimentation of particulate matter in construction wastewater from affecting the accuracy of wastewater test results, this application allows the staff to drive the spherical filter screen to rotate by driving the component, thereby making the spherical filter screen and the stirring blade rotate synchronously, thus stirring the construction wastewater, improving the uniformity of particulate matter dispersion in the construction wastewater, and ensuring the accuracy of wastewater test results.

[0024] 2. In this application, after the pump body is working, it draws construction sewage from the water storage tank through the pumping pipe. The sewage is discharged to the transfer box through the outlet pipe. The spherical filter screen plays a good filtering role for the water entering the pumping pipe, reducing the probability of large pieces of construction waste in the sewage clogging the pumping pipe and ensuring the normal operation of the pumping components.

[0025] 3. In this application, the spiral-shaped stirring blades on the outer wall of the spherical filter can agitate the construction particles at the bottom of the water storage tank, promoting the uniform mixing of construction wastewater in the water storage tank. The overflow hole allows some of the particles carried by the stirring blades to fall back, which is beneficial to improving the mixing effect of various components in the construction wastewater.

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] like Figure 1-5As shown in the embodiment of this application, a building wastewater discharge detection device is disclosed, including a base 1 (with a support leg 12 fixed to the bottom of the base 1), a pad 2 fixed to the top of the base 1, a water storage tank 3 fixed to the upper end of the pad 2, and an operating platform 4 fixed to the top of the base 1 and located on one side of the water storage tank 3. A spherical filter screen 5 is arranged inside the water storage tank 3 near its bottom, and a stirring blade 51 is arranged on the outside of the spherical filter screen 5. A driving assembly 6 for driving the spherical filter screen 5 to rotate is arranged on the base 1. A mounting frame 41 is fixed on the operating platform 4, and a transfer box 7 is fixed to the top of the mounting frame 41. A building wastewater detection device is arranged on the operating platform 4 for spherical filter screen 5 to rotate. Wastewater is drawn into the transfer box 7 by a pumping assembly 8. A rotating shaft 42 is rotatably mounted on the operating platform 4 below the transfer box 7. A turntable 421 is fixed to the upper end of the rotating shaft 42. A rotating assembly 9 is provided on the operating platform 4 to drive the turntable 421 to rotate. Multiple sampling assemblies 10 are provided near the edge of the turntable 421. A discharge assembly 11 is provided on the transfer box 7 to discharge the construction wastewater inside into the sampling assembly 10. A COD detector 43 is also provided on the operating platform 4 located on one side of the turntable 421 (the COD detector 43 is a conventional detection tool in the field of wastewater detection, and the illustration is only a simplified diagram).

[0034] The spherical filter screen 5 effectively intercepts construction wastewater entering the pumping assembly 8, preventing large pieces of construction debris from affecting the normal operation of the pumping assembly 8. The construction wastewater is pumped into the transfer box 7 by the pumping assembly 8, and then enters the sampling assembly 10 through the discharge assembly 11. After one set of sampling assemblies 10 is filled with construction wastewater sample, the rotating assembly 9 drives the turntable 421 to rotate, allowing the spare pumping assembly 8 to be used for sampling. Subsequently, the staff places the sampling assembly 10 into the COD analyzer 43 for wastewater testing. To prevent the sedimentation of particulate matter in the construction wastewater from affecting the accuracy of the wastewater test results, the staff drives the spherical filter screen 5 to rotate by the driving assembly 6, thereby making the spherical filter screen 5 and the stirring blade 51 rotate synchronously, thus stirring the construction wastewater, improving the uniformity of particulate matter dispersion in the construction wastewater, and ensuring the accuracy of the wastewater test results.

[0035] The pumping assembly 8 includes a pump body 81 fixed to the top of the operating table 4, a pumping pipe 82 fixed to and connected to the inlet end of the pump body 81, and an outlet pipe 83 fixed to and connected to the outlet end of the pump body 81. The end of the outlet pipe 83 away from the pump body 81 passes through the top of the transfer box 7 and extends into the transfer box 7. The pumping pipe 82 passes through the base 1, the bottom of the water storage tank 3 and the bottom of the spherical filter screen 5 in sequence and extends into the spherical filter screen 5. The axis of the pipe section of the pumping pipe 82 away from the pump body 81 coincides with the axis of the water storage tank 3, and the center of the spherical filter screen 5 is located on the axis of the water storage tank 3.

[0036] After the pump body 81 starts working, it draws construction sewage from the water storage tank 3 through the water pumping pipe 82. The sewage is discharged into the transfer box 7 through the water outlet pipe 83. The spherical filter screen 5 plays a good filtering role for the water entering the water pumping pipe 82, reducing the probability of large pieces of construction waste in the sewage clogging the water pumping pipe 82 and ensuring the normal operation of the water pumping component 8.

[0037] The drive assembly 6 includes a cover 61 fixed to the bottom wall of the water storage tank 3 and a central shaft 62 that passes through the top of the cover 61 and is rotatably connected to the cover 61. The cover 61 is a cylindrical cover structure with an open bottom and a hollow interior. The upper end of the central shaft 62 is fixed to the bottom of the spherical filter screen 5. The central shaft 62 and the top of the cover 61 are sealed by a rotating shaft seal. The section of the water pump 82 away from the pump body 81 passes through the central shaft 62 and is clearance-fitted. The drive assembly 6 also includes a fan blade 63 fixedly sleeved on the central shaft 62 and located inside the cover 61, a high-pressure blower 64 fixed to the top of the base 1, and a blower pipe 65 fixed to and connected to the air outlet of the high-pressure blower 64. The end of the blower pipe 65 away from the high-pressure blower 64 passes through the bottom of the base 1 and the water storage tank 3 in sequence and is set towards the edge of the fan blade 63.

[0038] After the high-pressure blower 64 starts working, it blows high-pressure air into the enclosure 61 through the air pipe 65, which causes the fan blades 63 to drive the central shaft 62 to rotate. Since the upper end of the central shaft 62 is fixed to the bottom of the spherical filter screen 5, and the central shaft 62 and the top of the enclosure 61 are kept sealed by a rotating shaft seal, the spherical filter screen 5 and the stirring blades 51 fixed on the spherical filter screen 5 rotate to stir the construction sewage in the water storage tank 3, promote the uniform dispersion of various components in the construction sewage, and ensure the accuracy of sewage test results.

[0039] An annular block 31 is fixed to the inner bottom wall of the water storage tank 3. The outer wall of the annular block 31 is in close contact with the inner wall of the water storage tank 3, and the inner wall of the annular block 31 is in close contact with the outer wall of the cover 61. The top of the annular block 31 is flush with the top of the cover 61. The annular block 31 reduces the amount of wastewater inside the water storage tank 3 that is difficult to be drawn by the pumping pipe 82.

[0040] The stirring blades 51 are spirally arranged around the outer wall of the spherical filter screen 5, and multiple overflow holes 511 are provided through the stirring blades 51. The spirally rising stirring blades 51 on the outer wall of the spherical filter screen 5 can agitate the construction particles at the bottom of the water storage tank 3, promoting the uniform mixing of construction wastewater in the water storage tank 3. The overflow holes 511 allow some of the particles carried up by the stirring blades 51 to fall back, which is beneficial to improving the mixing effect of various components in the construction wastewater.

[0041] The discharge assembly 11 includes a drain pipe 111 fixed to and connected to the bottom of the transfer box 7 and a solenoid valve 112 disposed on the drain pipe 111; multiple sampling assemblies 10 are evenly distributed about the axis of the turntable 421. Each sampling assembly 10 includes a mounting block 101 fixed to the top of the turntable 421. The top of the mounting block 101 is provided with a mounting groove 1011. The sampling assembly 10 also includes a sampling tube 102 that is inserted into the mounting groove 1011 and a funnel 103 that is detachably connected to the upper end of the sampling tube 102. The distance between the axis of the drain pipe 111 and the axis of the turntable 421 is equal to the distance between the axis of the sampling tube 102 and the axis of the turntable 421, and the inner diameter of the top of the funnel 103 is greater than the outer diameter of the drain pipe 111.

[0042] After the solenoid valve 112 is opened, the sewage in the transfer box 7 enters the funnel 103 through the drain pipe 111, and then enters the sampling tube 102. When the construction sewage collected in the sampling tube 102 reaches the liquid level, the solenoid valve 112 closes. The rotating assembly 9 then drives the turntable 421 and the rotating shaft 42 to rotate, moving the next set of sampling tubes 102 without sewage to below the drain pipe 111. The process of opening the solenoid valve 112 to collect construction sewage is then repeated. The design of the funnel 103 allows the solenoid valve 112 to be opened for sewage collection without the drain pipe 111 being completely aligned with the solenoid valve 112.

[0043] Multiple cameras 71 are fixed at the bottom of the transfer box 7, located near the drain pipe 111. A controller 44, electrically connected to both the cameras 71 and the solenoid valve 112, is fixed on the operating table 4. The cameras 71 allow staff to observe the position of the funnel 103 and the liquid level collection in the sampling tube 102 in real time, and transmit the monitoring results to the controller 44 in real time, enabling staff to control the operation of the solenoid valve 112 based on the monitoring results.

[0044] The rotating assembly 9 includes a vertical plate 91 fixed to the top of the operating table 4, a rotating rod 92 rotatably mounted on the vertical plate 91, a motor 93 fixed to the vertical plate 91 and used to drive the rotating rod 92 to rotate, a worm gear 94 fixed to the end of the rotating rod 92 away from the vertical plate 91, and a worm wheel 95 fixedly sleeved on the rotating shaft 42 and meshing with the worm gear 94. After the motor 93 is working, it drives the rotating rod 92 to rotate, thereby causing the rotating rod 92 to drive the worm gear 94 to rotate, which in turn causes the worm wheel 95 meshing with the worm gear 94, the rotating shaft 42 fixed to the worm wheel 95, and the turntable 421 fixed to the upper end of the rotating shaft 42 to rotate, thereby controlling the sampling tube 102 that has not collected sewage to move below the drain pipe 111 and perform the sewage collection action.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
