Description

Technical Field

[0001] This utility model relates to the field of sludge settling ratio detection device, and more particularly to a sludge settling ratio detection device. Background Technology

[0002] The sludge settling ratio refers to the ratio of the volume of settled sludge to the volume of the mixed liquid after the activated sludge from the aeration tank is quickly poured into a 1000ml graduated cylinder to full volume and allowed to settle for 30 minutes. It is also known as the sludge settling volume 30ml. This indicator reflects the amount of sludge during the operation of the aeration tank and can control and adjust the amount of activated sludge discharged. It is also a direct reflection of abnormal phenomena such as sludge bulking.

[0003] A search revealed a Chinese patent disclosure: an automatic sludge settling ratio detection device (Authorization Announcement No.: CN217520974U). This application provides an automatic sludge settling ratio detection device, belonging to the technical field of sludge settling ratio detection. Specifically, it includes a container for holding the liquid to be tested, and a sensor detection mechanism is provided on the outer wall of the container. The sensor detection mechanism is configured to detect the boundary between the clear water and sludge in the container after a preset time. This application's processing solution reduces labor costs.

[0004] However, in the actual application of this patented technology, the existing devices, when automatically detecting the sludge settling ratio, add the sludge into the measuring cylinder and let it stand for half an hour before observation. There is a lack of a device for mixing the sludge. Mixing can change the movement state of the sludge particles, thereby affecting its settling performance, and thus affecting the sludge settling speed and settling effect. Utility Model Content

[0007] The mixing mechanism includes a motor, a rotating rod, a connecting rod, and a concave plate. The motor is located at the top of the measuring cylinder, and the output end of the motor is fixedly connected to the rotating rod. One side of the connecting rod is fixedly connected to the rotating rod, and one side of the concave plate is fixedly connected to the connecting rod.

[0011] Preferably, the bottom of the measuring cylinder is connected to a delivery pipe, the surface of the delivery pipe is fitted with a solenoid valve, and the bottom of the delivery pipe extends through the base to the outside of the base plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, by setting up a mixing mechanism, in the sludge settling ratio test, sludge is added into the inside of the measuring cylinder through the feeding hopper, and a fixing block is fixed on the top of the measuring cylinder. The output end of the motor drives the rotating rod to rotate, and the rotation of the rotating rod can drive the connecting rod to rotate.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-5 An embodiment of this utility model is provided: a sludge settling ratio detection device, including a base plate 1, a base 2 is provided on the top of the base plate 1, a measuring cylinder 3 is fixedly connected to the top of the base 2, a feeding hopper 4 is connected to one side of the measuring cylinder, a mixing mechanism 5 is provided on the top of the measuring cylinder 3, and a fixing mechanism 6 is provided on the top of the base plate 1.

[0024] The mixing mechanism 5 includes a motor 501, a rotating rod 502, a connecting rod 503, and a concave plate 504. The motor 501 is located on the top of the measuring cylinder 3. The output end of the motor 501 is fixedly connected to the rotating rod 502. One side of the connecting rod 503 is fixedly connected to the rotating rod 502. One side of the concave plate 504 is fixedly connected to the connecting rod 503.

[0025] Through the above technical solution, by setting up a mixing mechanism 5, in the sludge settling ratio test, sludge is added into the inside of the measuring cylinder 3 through the feeding hopper 4, and the fixing block 7 is clamped on the top of the measuring cylinder 3. The output end of the motor 501 drives the rotating rod 502 to rotate. The rotation of the rotating rod 502 can drive the connecting rod 503 to rotate. Through the rotating rod 502 of the connecting rod 503, the concave plate 504 is driven to rotate, which can mix the sludge inside the measuring cylinder 3, thereby accelerating the sludge settling speed and settling effect.

[0026] Specifically, the fixing mechanism 6 includes a fixing plate 601, a positioning plate 602, a spring 603, a plug rod 604, and a plug hole 605. The plug hole 605 is opened on both sides of the base 2. The plug rod 604 is inserted into the inside of the plug hole 605. One side of the plug rod 604 is fixedly connected to the positioning plate 602. The positioning plate 602 is set on the top of the base plate 1. The fixing plate 601 is fixed on the top of the base plate 1. One side of the spring 603 is fixedly connected to the positioning plate 602. One side of the fixing plate 601 is fixedly connected to the spring 603.

[0027] Through the above technical solution, by setting the fixing mechanism 6, pulling the positioning plate 602 can cause the spring 603 to retract, placing the base 2 inside the base plate 1. When the positioning plate 602 is released, the spring 603 relaxes, and the insertion rod 604 can be inserted into the insertion hole 605, which can fix the base 2 and the measuring cylinder 3, facilitating the mixing of sludge.

[0028] Specifically, a fixing block 7 is provided at the top of the measuring cylinder 3, and a slot 8 is provided at the bottom of the fixing block 7. The slot 8 is engaged with the top of the measuring cylinder 3.

[0029] Through the above technical solution, by setting the fixing block 7 and the slot 8, the slot 8 is fixed on the top of the measuring cylinder 3, which plays a role in fixing the fixing block 7.

[0030] Specifically, a positioning rod 9 is fixedly connected to one side of the positioning plate 602, and a fixing rod 10 is fixedly connected to one side of the fixing plate 601. One side of the positioning rod 9 is slidably connected to the inside of the fixing rod 10, and a spring 603 is sleeved on the surface of the fixing rod 10 and the positioning rod 9.

[0031] Through the above technical solution, by setting the positioning rod 9 and the fixing rod 10, when the spring 603 extends and retracts, the positioning rod 9 slides inside the fixing rod 10, which plays a stabilizing role when the spring 603 extends and retracts.

[0032] Specifically, the concave plate 504 has a cleaning sponge 11 inside, the bottom of the fixing block 7 has a placement groove 12, and the motor 501 is located inside the placement groove 12.

[0033] Through the above technical solution, by setting up the cleaning cotton 11, after the sludge settling test is completed, the cleaning cotton 11 is installed inside the concave plate 504. The rotation of the motor 501 can drive the cleaning cotton 11 to rotate, which can clean the inner wall of the measuring cylinder 3.

[0034] Specifically, the bottom of the measuring cylinder 3 is connected to a conveying pipe 13, and a solenoid valve 14 is fitted on the surface of the conveying pipe 13. The bottom of the conveying pipe 13 extends through the base 2 to the outside of the base plate 1.

[0035] With the above technical solution, by setting up a conveying pipe 13 and a solenoid valve 14, after the sludge settling ratio test is completed, the solenoid valve 14 is opened and the sludge is discharged through the conveying pipe 13.

[0036] Working principle: During use, pulling the positioning plate 602 causes the spring 603 to retract, placing the base 2 inside the base plate 1. Releasing the positioning plate 602 releases the spring 603, allowing the insertion rod 604 to be inserted into the insertion hole 605, thus fixing the base 2 and the measuring cylinder 3. In sludge settling ratio testing, sludge is added to the measuring cylinder 3 through the feeding hopper 4. The fixing block 7 is secured to the top of the measuring cylinder 3. The output of the motor 501 drives the rotating rod 502 to rotate. The rotation of rod 502 can drive the connecting rod 503 to rotate. The rotating rod 502 of the connecting rod 503 drives the concave plate 504 to rotate, which can mix the sludge inside the measuring cylinder 3, accelerate the settling speed and settling effect of the sludge. After the sludge settling test is completed, the cleaning cotton 11 is installed inside the concave plate 504. The rotation of motor 501 can drive the cleaning cotton 11 to rotate, which can clean the inner wall of the measuring cylinder 3. After the sludge settling ratio test is completed, the solenoid valve 14 is opened, and the sludge is discharged through the conveying pipe 13.
