Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sludge scraper operation detection device. Background Technology

[0002] The radial flow sedimentation tanks in wastewater treatment plants are equipped with center-driven sludge scrapers, which are widely used for scraping sludge in radial flow sedimentation tanks with smaller diameters (not exceeding 18m).

[0003] Because the scraper blades of the center-driven sludge scraper are located at the bottom of the radial flow sedimentation tank, they may detach during operation. However, only the motor driving the scraper can be seen running beside the tank; the actual rotation of the scraper itself cannot be observed. Wastewater treatment continues even when the scraper is not rotating, and the failure to rotate is only assessed when serious abnormalities appear in the sedimentation tank several days after the scraper detaches, thus affecting the quality of wastewater treatment. Utility Model Content

[0004] The technical problem this invention aims to solve is that scrapers may fall off during use, making it difficult for workers to visually observe whether the scraper is rotating. Furthermore, wastewater treatment continues even when the scraper is not rotating, affecting the quality of wastewater treatment. The purpose is to provide a scraper operation detection device. When the scraper rotates to the bottom of the detection rod, it causes the detection rod to swing. The top of the detection rod presses the contact of a microswitch, illuminating a warning light. Workers can then directly observe whether the scraper is rotating, ensuring the quality of wastewater treatment.

[0005] This utility model is achieved through the following technical solution:

[0006] A sludge scraper operation detection device includes a rod mounting bracket, a warning light, a detection rod, and a micro switch. The rod mounting bracket is fixedly connected to the inner side wall of a radial flow sedimentation tank. The detection rod is swayably connected to the rod mounting bracket, with its lower end located inside the radial flow sedimentation tank and its bottom lower than the top of the scraper blade of the sludge scraper. The micro switch and the warning light are both installed above the radial flow sedimentation tank. The micro switch is electrically connected to the warning light. In operation, when the scraper blade rotates to the bottom of the detection rod, it causes the detection rod to sway. The top of the detection rod presses against the contact of the micro switch, illuminating the warning light.

[0007] The beneficial effects of this utility model are as follows: by mounting the probe rod on a bracket with a swingable connecting rod, and placing the lower end of the probe rod inside the radial flow sedimentation tank, with the bottom of the probe rod lower than the top of the scraper blade of the sludge scraper, a micro switch is installed above the radial flow sedimentation tank, and an electrical warning light is connected to the top of the micro switch. In operation, when the central drive sludge scraper blade rotates and scrapes sludge, the scraper blade rotates to the bottom of the probe rod, touching it. As the scraper blade continues to rotate, the probe rod swings. When the probe rod swings, the top of the probe rod presses the contact of the micro switch. At the moment of pressing, the warning light is connected to the power supply, and the warning light illuminates. Workers can then directly observe whether the scraper blade is rotating, and take appropriate measures and repair the sludge scraper to ensure the quality of wastewater treatment.

[0008] In some embodiments, the probe rod is vertically mounted on the rod mounting bracket, and the bottom of the probe rod is spherical. By setting the bottom of the probe rod to be spherical, the frictional force when the scraper contacts the bottom of the probe rod is reduced, allowing the probe rod to detect whether the scraper is rotating without affecting the normal operation of the scraper.

[0009] In some embodiments, the rod mounting bracket is in the shape of a long strip plate. One end of the rod mounting bracket is fixedly connected to the inner side wall of the radial flow sedimentation tank, and the other end is located inside the radial flow sedimentation tank. The probe rod is hinged to the free end of the rod mounting bracket. By fixing one end of the rod mounting bracket to the inner side wall of the radial flow sedimentation tank and the other end to the radial flow sedimentation tank, it is convenient to install the probe rod inside the radial flow sedimentation tank, so that the bottom of the probe rod is located in the bottom area of ​​the radial flow sedimentation tank.

[0010] In some embodiments, the bottom of the rod mounting bracket is provided with ribs, which are right-angled triangular plates. Providing ribs at the bottom of the rod mounting bracket improves its strength and rigidity.

[0011] In some embodiments, the device further includes a mounting ball. The rod mounting bracket has a rod mounting hole, which is a through hole. A spherical mounting groove is provided on the side wall of the rod mounting hole. The mounting ball is rotatably connected to the spherical mounting groove, and the probe rod is fixedly connected to the mounting ball. By providing a spherical mounting groove on the side wall of the rod mounting hole, the mounting ball can be rotatably connected within the groove, preventing it from falling out of the rod mounting hole during operation. Furthermore, the probe rod is fixedly connected to the mounting ball, allowing the mounting ball to rotate within the mounting groove under the action of the scraper during operation. This enables the upper end of the probe rod to contact the contacts of the microswitch during swinging, thus pressing the contact.

[0012] In some embodiments, the mounting ball has a mounting through hole, the central axis of which passes through the center of the mounting ball. The probe rod passes through the mounting through hole and is welded to both ends of the mounting through hole. By providing a mounting through hole on the mounting ball for the probe rod to pass through and welding it to both ends of the mounting through hole, the probe rod is thus fixedly connected to the mounting ball.

[0013] In some embodiments, the diameter of the rod mounting hole is greater than twice the diameter of the probe rod. By making the diameter of the rod mounting hole greater than twice the diameter of the probe rod, the probe rod has a sufficient swing amplitude to press the contacts of the microswitch during swing.

[0014] In some embodiments, a switch mounting bracket is further included. The switch mounting bracket is connected to the top of the sidewall of the radial flow sedimentation tank. The switch mounting bracket is generally L-shaped, and its free end is connected to the micro switch. By connecting the switch mounting bracket to the top of the sidewall of the radial flow sedimentation tank, the micro switch is connected above the radial flow sedimentation tank and above the probe rod, ensuring that the upper end of the probe rod can press the contacts of the micro switch when it swings.

[0015] In some embodiments, the bottom of the switch mounting bracket is provided with ribs, which are connected to the corners of the switch mounting bracket. A switch clamp is installed at the automatic end of the switch mounting bracket, and the micro switch is connected to the switch mounting bracket via the switch clamp. By providing ribs at the bottom of the switch mounting bracket, the strength and rigidity of the switch mounting bracket are increased, and the switch clamp is installed at the automatic end of the switch mounting bracket, allowing for a non-destructive connection of the micro switch to the switch mounting bracket.

[0016] In some embodiments, a lamp bracket is also included. The lamp bracket is triangular in shape, and its bottom is fixedly connected to the upper free end of the switch mounting bracket. A lamp clamp is installed on the free end of the switch mounting bracket, and the warning light is connected to the lamp bracket via the lamp clamp. Alternatively, by mounting the lamp bracket on the switch mounting bracket and providing a lamp clamp on the free end of the lamp mounting bracket, a non-destructive connection between the warning light and the lamp bracket can be achieved.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] 1. The working scraper of the center-driven sludge scraper rotates to scrape sludge. When the scraper rotates to the bottom of the probe rod, it touches the bottom of the probe rod. When the scraper continues to rotate, it causes the probe rod to swing. When the probe rod swings, the top of the probe rod presses the contact of the micro switch. At the moment it is pressed, the warning light is connected to the power supply, and the warning light lights up. The staff can directly observe whether the scraper is rotating to ensure the quality of sewage treatment.

[0019] 2. By setting a spherical mounting groove on the side wall of the rod mounting hole, the mounting ball can be rotatably connected in the spherical mounting groove, preventing the mounting ball from falling out of the rod mounting hole during operation. The probe rod is also fixedly connected to the mounting ball, so that during operation, the probe rod can make the mounting ball rotate in the mounting groove under the action of the scraper, so that the upper end of the probe rod can touch the contact of the micro switch when swinging, and press the contact.

[0032] Example

[0033] like Figures 1-5As shown, this embodiment provides a working detection device for a sludge scraper 10, including a rod mounting bracket 40, a detection rod 30, and a micro switch 31. The rod mounting bracket 40 is fixedly connected to the inner side wall of a radial flow sedimentation tank 20. The detection rod 30 is swayably connected to the rod mounting bracket 40, with its lower end located inside the radial flow sedimentation tank 20, and its bottom lower than the top of the scraper blade 11 of the sludge scraper 10. The micro switch 31 and the warning light 32 are both installed above the radial flow sedimentation tank 20. The micro switch 31 is electrically connected to the warning light 32. In the working state, when the scraper blade 11 rotates to the bottom of the detection rod 30, it causes the detection rod 30 to swing. The top of the detection rod 30 presses the contact 311 of the micro switch 31, and the warning light 32 illuminates. In order to facilitate the operation of the central drive sludge scraper 10, the working scraper 11 rotates to scrape sludge. When the scraper 11 rotates to the bottom of the probe rod 30, it touches the bottom of the probe rod 30. When the scraper 11 continues to rotate, it causes the probe rod 30 to swing. When the probe rod 30 swings, the top of the probe rod 30 presses the contact 311 of the micro switch 31. At the moment it is pressed, the warning light 32 is connected to the power supply, and the warning light 32 lights up. The operator can then directly observe whether the scraper 11 is rotating.

[0034] Specifically, a monitoring system can also be set up and connected to the control center. The monitoring system is aimed at the warning light 32 so that the control center can remotely monitor whether the warning light 32 is continuously or intermittently connected, thereby realizing remote monitoring of whether the scraper 11 of the central drive scraper 10 is rotating.

[0035] See Figures 1-5 The detection rod 30 is vertically mounted on the rod mounting bracket 40, and the bottom of the detection rod 30 is spherical. By making the bottom of the detection rod 30 spherical, the frictional force when the scraper 11 contacts the bottom of the detection rod 30 is reduced. Specifically, the detection rod 30 is made of stainless steel tubing to prevent it from rusting during use.

[0036] See Figures 1-5 The rod mounting bracket 40 is a long, narrow plate. One end of the rod mounting bracket 40 is fixedly connected to the inner side wall of the radial flow sedimentation tank 20, and the other end is located inside the radial flow sedimentation tank 20. The probe rod 30 is hinged to the free end of the rod mounting bracket 40. By fixing one end of the rod mounting bracket 40 to the inner side wall of the radial flow sedimentation tank 20 and the other end to the radial flow sedimentation tank 20, it is easy to install the probe rod 30 inside the radial flow sedimentation tank 20, so that the bottom of the probe rod 30 is located in the bottom area of ​​the radial flow sedimentation tank 20.

[0037] See Figure 1The bottom of the rod mounting bracket 40 is provided with a rib plate, which is in the shape of a right-angled triangular plate. The strength and rigidity of the rod mounting bracket 40 are improved by providing a rib plate at the bottom of the rod mounting bracket 40.

[0038] See Figure 1 and Figure 5 The device also includes a mounting ball 41. The rod mounting bracket 40 has a rod mounting hole 43, which is a through hole. A spherical mounting groove 42 is provided on the side wall of the rod mounting hole 43. The mounting ball 41 is rotatably connected to the spherical mounting groove 42, and the probe rod 30 is fixedly connected to the mounting ball 41. By providing a spherical mounting groove 42 on the side wall of the rod mounting hole 43, the mounting ball 41 can be rotatably connected to the groove, preventing it from falling out of the hole during operation. The probe rod 30 is also fixedly connected to the mounting ball 41, allowing the mounting ball 41 to rotate within the groove under the action of the scraper 11 during operation. This enables the upper end of the probe rod 30 to touch the contact point of the micro switch 31 during swinging, pressing the contact 311.

[0039] See Figure 1 and Figure 5 The mounting ball 41 has a mounting through hole, the central axis of which passes through the center of the mounting ball 41. The probe rod 30 passes through the mounting through hole and is welded to both ends of the mounting through hole. By providing a mounting through hole on the mounting ball 41 for the probe rod 30 to pass through and welding it to both ends of the mounting through hole, the probe rod 30 is thus fixedly connected to the mounting ball 41.

[0040] See Figure 1 and Figure 5 The diameter of the rod mounting hole 43 is greater than twice the diameter of the probe rod 30. By making the diameter of the rod mounting hole 43 greater than twice the diameter of the probe rod 30, the probe rod 30 can have a sufficient swing amplitude to press the contact 311 of the micro switch 31 when swinging.

[0041] See Figure 1 and Figure 4 The system also includes a switch mounting bracket 50, which is connected to the top of the side wall of the radial flow sedimentation tank 20. The switch mounting bracket 50 is generally L-shaped, and its free end is connected to the micro switch 31. By connecting the switch mounting bracket 50 to the top of the side wall of the radial flow sedimentation tank 20, the micro switch 31 is connected above the radial flow sedimentation tank 20 and above the probe rod 30, ensuring that the upper end of the probe rod 30 can press the contact of the micro switch 31 when it swings.

[0042] See Figure 1 and Figure 4 The bottom of the switch mounting bracket 50 is provided with ribs, which are connected to the corners of the switch mounting bracket 50. A switch clamp 501 is installed at the automatic end of the switch mounting bracket 50, and the micro switch 31 is connected to the switch mounting bracket 50 via the switch clamp 501. By providing ribs at the bottom of the switch mounting bracket 50, the strength and rigidity of the switch mounting bracket 50 are increased, and the switch clamp 501 installed at the automatic end of the switch mounting bracket 50 enables a non-destructive connection between the micro switch 31 and the switch mounting bracket 50.

[0043] See Figure 1 and Figure 4 The system also includes a lamp bracket 51, which is triangular in shape. The bottom of the lamp bracket 51 is fixedly connected to the upper free end of the switch mounting bracket 50. A lamp clamp 511 is installed on the free end of the switch mounting bracket 50, and the warning light 32 is connected to the lamp bracket 51 through the lamp clamp 511. Alternatively, by mounting the lamp bracket 51 on the switch mounting bracket 50 and providing a lamp clamp 511 on the free end of the lamp mounting bracket, a non-destructive connection between the warning light 32 and the lamp bracket 51 can be achieved.

[0044] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
