Description

Technical Field

[0001] This application relates to the technical field of sewage treatment equipment, and particularly to a device for automatically detecting and cleaning the sludge sedimentation ratio. Background Art

[0002] The sludge sedimentation ratio (SV30) is an important indicator for evaluating sludge performance and system operation status. The accuracy and timeliness of the sludge sedimentation ratio play a crucial role in optimizing the sewage treatment process, improving treatment efficiency, and ensuring the effluent quality. In the traditional detection method of the sludge sedimentation ratio, it mainly relies on manual operations, such as manually injecting sludge samples and manually reading the values, which have problems such as low detection accuracy, cumbersome operation, and long time consumption.

[0003] Meanwhile, during the sedimentation process, the sludge will adhere to the inner wall of the graduated cylinder (test tube), causing the line of sight of the inner wall to be blocked and making it impossible to clearly see the scale position of the stratification. It is often necessary to take out the graduated cylinder for manual cleaning to ensure the light transmissibility of the graduated cylinder. However, the traditional manual cleaning method not only has a large labor intensity and low efficiency, but also is difficult to ensure the consistency of the cleaning effect.

[0004] In summary, there is an urgent need for a sludge sedimentation detection device that can reduce dependence on manual labor and can automatically clean to solve the above technical problems. Utility Model Content

[0035] This application provides a device for automatic detection and cleaning of sludge sedimentation ratio, which is used to automatically clean the test tube, ensure the light transmittance of the test tube, and improve the detection accuracy. The specific implementation process of this application is described as follows.

[0036] Please refer to Figures 1 to 4 , a device for automatic detection and cleaning of sludge sedimentation ratio provided by this application includes:

[0037] A detection camera 01, a cleaning component 02, and a detection component 03; the detection component 03 includes a test tube 04, and the test tube 04 is used for the sedimentation of sludge samples; a scale is provided on the wall of the test tube 04, the detection camera 01 is arranged in the horizontal direction of the test tube 04, and the shooting direction of the detection camera 01 faces the scale, and the detection camera 01 is used to take images of the test tube 04; the cleaning component 02 is located above the test tube 04, and the cleaning component 02 is used to clean the inner wall of the test tube 04.

[0038] The detection camera 01 is placed horizontally with respect to the test tube 04 to ensure that the entire interior of the test tube 04 and the scale area on the tube wall can be clearly captured. The shooting direction of the detection camera 01 directly faces the scale, facilitating the subsequent accurate identification by the computer device of the height of sludge settlement. The detection camera 01 is electrically connected to the computer device, and the photos taken by the detection camera 01 are directly transmitted to the computer device for reading. Additionally, the detection camera 01 can be set for timed shooting. The timed shooting interval can be once every 3 minutes or once every 5 minutes. The specific timed shooting interval is not limited here and shall be subject to what can be actually achieved.

[0039] The wall of the test tube 04 is engraved with precise scales for measuring the height of sludge settlement during the static process, thereby facilitating the computer device to calculate the sludge settlement ratio. The test tube 04 can be made of transparent and corrosion-resistant materials such as glass or high-quality plastic to ensure the clarity of observation and the stability for long-term use.

[0040] The cleaning component 02 is located above the test tube 04 to facilitate a comprehensive cleaning of the inner wall of the test tube 04. During cleaning, the sludge sample in the test tube 04 needs to be removed, and then the cleaning component 02 is started. The cleaning component 02 moves downward into the test tube 04 to clean the inner wall of the test tube 04. The cleaning process can be automated through a preset program or remote control, which can reduce manual intervention and improve efficiency and safety.

[0041] In this embodiment, from the detection of the sludge settlement ratio to the cleaning of the test tube 04, the entire process can be automated, greatly reducing the manual labor intensity and improving work efficiency; the setting of the cleaning component 02 makes the cleaning of the test tube 04 simple and fast, reducing equipment damage and measurement errors caused by improper cleaning.

[0042] In an alternative embodiment, the cleaning component 02 includes a brush 05, a first motor 06, and a reciprocating driving member; the brush 05 is located directly above the test tube 04, the end of the brush 05 is connected to the first motor 06, and the first motor 06 is used to control the rotation of the brush 05; the driving member is movably connected to the first motor 06 and is used to control the first motor 06 to perform reciprocating up and down movements.

[0043] The brush 05 is arranged directly above the test tube 04, and the end of the brush 05 is directly connected to the first motor 06. The brush 05 can fully cover every area of the inner wall of the test tube 04. The brush 05 can be made of flexible materials and has a certain length, width, and flexibility to ensure the cleaning effect. When the brush 05 rotates, the bristles of the brush 05 can penetrate into the inner wall of the test tube 04 to effectively remove the attached sludge and residues.

[0044] The reciprocating drive is movably connected to the first motor 06 and is used to control the first motor 06 and the brush 05 connected to the first motor 06 to perform up-and-down reciprocating motion, so that the brush 05 can clean back and forth along the length direction of the test tube 04, ensuring that the inner wall can be fully cleaned. Through the cooperation of the first motor 06 and the reciprocating drive, the brush 05 can not only rotate itself but also move up and down, enabling the inner wall of the test tube 04 to be fully cleaned and improving the cleaning effect.

[0045] In this alternative embodiment, the reciprocating drive is a pneumatic actuator, and the telescopic end of the pneumatic actuator is connected to the first motor 06. The telescopic direction of the telescopic end of the pneumatic actuator is consistent with the length direction of the test tube 04, and mechanical connection methods such as flange, thread, and pin can be used to connect the telescopic end and the first motor 06.

[0046] In this alternative embodiment, the reciprocating drive includes a second motor 07 and a travel plate 08; the travel plate 08 is parallel to the brush 05, a ball screw 09 is provided on the travel plate 08, the second motor 07 is fixed on the travel plate 08 and connected to the ball screw 09; a slider 10 is provided on the side of the first motor 06, and the first motor 06 is connected to the ball screw 09 through the slider 10, and the second motor 07 is used to control the movement of the first motor 06 through the ball screw 09.

[0047] The travel plate 08 is arranged parallel to the brush 05, ensuring the stability of the relative position relationship between the first motor 06 and the brush 05 during the movement. By converting the rotational motion of the ball screw 09 into the linear motion of the first motor 06, the ball screw 09 is installed on the travel plate 08, one end is connected to the second motor 07, and the other end is movably connected to the travel plate 08.

[0048] The slider 10 is installed on the side of the first motor 06 and is used to cooperate with the ball screw 09 to convert the rotational motion of the ball screw 09 into the linear motion of the first motor 06.

[0049] When the test tube 04 needs to be cleaned, the second motor 07 drives the ball screw 09 to rotate, and the rotation of the ball screw 09 causes the slider 10 to move along the axial direction of the ball screw 09. Since the slider 10 is connected to the first motor 06, the first motor 06 moves with the movement of the slider 10, realizing the linear reciprocating motion of the first motor 06, that is, realizing the linear reciprocating motion of the brush 05.

[0050] In an alternative embodiment, the brush 05 is detachably connected to the first motor 06. In this embodiment, the detachable connection means can be screw connection, snap connection, bolt connection, etc. Through the detachable connection, the brush 05 can be replaced, maintained and cleaned at any time, so as to ensure the cleaning ability of the brush 05. For test tubes 04 of different sizes, the brush 05 of different sizes can also be replaced at any time.

[0051] In an alternative embodiment, the detection assembly 03 further includes a sampling pipeline 11 and a cleaning pipeline 12; the sampling pipeline 11 is located below the test tube 04 and is connected to the test tube 04. The cleaning pipeline 12 is connected to the sampling pipeline 11. The sampling pipeline 11 is used to transport the sludge sample into the test tube 04, and the cleaning pipeline 12 is used to cooperate with the cleaning assembly 02 to clean the test tube 04.

[0052] The sampling pipeline 11 is located below the test tube 04 and is connected to the test tube 04 through interfaces such as valves and connectors. This enables the sludge sample to enter the test tube 04 from below, avoiding problems such as sample splashing or contamination of the detection camera 01 when adding from above; the main function of the sampling pipeline 11 is to transport the sludge sample into the test tube 04. The sampling pipeline 11 is connected to a sludge sample storage container (such as a storage tank, bottle, sludge tank, etc.), and the sludge sample is sent into the test tube 04 by means of a pump, gravity or other means. A flow control device can be equipped in the sampling pipeline 11 to ensure that the amount of sludge sample added each time is accurate and consistent.

[0053] The cleaning pipeline 12 is connected to the sampling pipeline 11, and the other end of the cleaning pipeline 12 can be connected to a cleaning liquid storage container (such as a water tank, cleaning liquid bottle, etc.); the main function of the cleaning pipeline 12 is to cooperate with the cleaning assembly 02 to clean the test tube 04. After detecting the sedimentation ratio of the sludge sample, a cleaning liquid (such as water, cleaning agent solution, etc.) is introduced into the test tube 04 through the cleaning pipeline 12, and at the same time, the brush 05 in the cleaning assembly 02 is started to rotate and reciprocate up and down to remove the sludge residues attached to the inner wall of the test tube 04.

[0054] By adding the sampling pipeline 11 and the cleaning pipeline 12, not only can the introduction of the sludge sample and the detection of the sedimentation ratio be automatically completed, but also the test tube 04 can be automatically cleaned, greatly improving the detection efficiency and accuracy, reducing manual intervention and errors. In addition, it is also easier to maintain and prolongs the service life.

[0055] In an alternative embodiment, solenoid valves 13 are respectively provided on the sample injection pipeline 11 and the cleaning pipeline 12. In this embodiment, by providing the solenoid valves 13, the solenoid valves 13 are closed when energized or de-energized. After injecting the sludge sample into the test tube 04, by closing the solenoid valves 13, the sample injection pipeline 11 and the cleaning pipeline 12 are closed, so that the sludge sample settles in the test tube 04. When the settling is completed, the sludge sample is poured out or removed by other means, and then the solenoid valve 13 in the cleaning pipeline 12 is opened to allow the cleaning liquid to enter the test tube 04 for cleaning the inner wall.

[0056] In an alternative embodiment, the detection assembly 03 includes at least three test tubes 04, which are arranged side by side, and the at least three test tubes 04 are respectively communicated with the sample injection pipeline 11. To ensure the accuracy of the measurement data, at least three groups of sedimentation experiments are set in this embodiment. Each group of sedimentation experiments is carried out through one test tube 04. The detection camera 01 can capture the scales and sedimentation effects on at least three test tubes 04 at one time. The at least three test tubes 04 are respectively connected to the sample injection pipeline 11 and the cleaning pipeline 12 below; in the cleaning stage, one cleaning assembly 02 can be provided above each test tube 04 to clean the inner walls of at least three test tubes 04 simultaneously, or only one cleaning assembly 02 can be provided to clean the inner walls of at least three test tubes 04 in sequence.

[0057] In addition, at the same sedimentation time, the scales of at least three test tubes 04 are respectively read according to the captured images, and the average value of these readings is calculated as the final data to improve the accuracy of the data.

[0058] In an alternative embodiment, an overflow port 14 is provided at the upper end of the test tube 04. By providing the overflow port 14, it helps to maintain the stability of the volume of the sludge sample in the test tube 04, prevent the influence of excessive sludge sample on the accuracy of the sedimentation result, and thus improve the reliability and repeatability of sludge sedimentation.

[0059] In an alternative embodiment, the overflow port 14 is located at the 1000 ml scale position of the test tube 04. The volume of the test tube 04 for sludge sedimentation is 1000 ml. By providing the overflow port 14 at the 1000 ml scale position, it is ensured that each sludge sedimentation test uses a 1000 ml sludge sample, guaranteeing the accuracy of the sedimentation result.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application.
