Description

Technical Field

[0001] This utility model relates to the technical field of wastewater testing devices, and more specifically, to an intelligent sludge settling ratio measuring device. Background Technology

[0002] The sludge settling ratio typically refers to the ratio of the volume of settled sludge to the original volume of the mixed liquor after standing in a 1000 mL graduated cylinder for 30 minutes in an aerobic biological wastewater treatment process. Measuring the sludge settling ratio is crucial in daily production operations and provides significant guidance for the routine operation of wastewater treatment plants. The results of the sludge settling ratio measurement can provide a reference for judging the concentration of activated sludge, flocculation and settling performance, and sludge quality in the biological treatment tank, thereby allowing for adjustments and optimization of the treatment process, improving wastewater treatment efficiency, and achieving better effluent quality.

[0003] Currently, sludge settling in wastewater treatment plants generally requires manual operation. On-duty personnel use a rope to pull a bucket and throw it into the observation port of the aerobic section of the biological treatment tank to collect samples, which are then poured into a graduated cylinder for measurement. Before sampling, the bucket needs to be manually used to mix the sludge multiple times, and then the mixture is immediately poured into a 1000 mL graduated cylinder. After waiting for 30 minutes, the measurement results are recorded. The entire operation is quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology in which the operation of measuring sludge settling ratio is relatively cumbersome, and to provide an intelligent sludge settling ratio measuring device that facilitates the measurement of sludge settling ratio.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An intelligent sludge settling ratio measuring device is provided, comprising a measuring component, a sampling component, a lifting mechanism, and a liquid delivery mechanism. The lifting mechanism is mounted on the measuring component, the sampling component is connected to the output end of the lifting mechanism, and the two ends of the liquid delivery mechanism are respectively connected to the measuring component and the sampling component.

[0007] This invention relates to an intelligent sludge settling ratio measuring device. When measuring the sludge settling ratio, a lifting mechanism is activated to lower the sampling component to the required sampling height within the biological treatment tank. The sampling component then collects the sample. After sampling, a liquid delivery mechanism is activated to deliver the sample to the measuring component for sludge settling ratio measurement. The lifting mechanism allows for easy lowering of the sampling component to the desired height, and the liquid delivery mechanism delivers the sample to the measuring component for sludge settling ratio measurement. This device is simple to operate and facilitates the measurement of the sludge settling ratio.

[0008] Furthermore, the sampling component includes a sampling cylinder, a one-way valve, and a first liquid pump. The sampling cylinder has an inlet and a connecting port. The one-way valve is located at the inlet, and the first liquid pump is located at the inlet. The two ends of the liquid delivery mechanism are respectively connected to the measuring component and the connecting port. After the sampling component reaches the required sampling height, the first liquid pump is activated, and the first liquid pump draws liquid through the one-way valve at the inlet into the sampling cylinder.

[0009] Furthermore, the first liquid pump includes a waterproof motor and a spiral blade. The waterproof motor is located inside the sampling cylinder, and the spiral blade is connected to the output end of the waterproof motor. After the sampling component reaches the required sampling height, the waterproof motor is started, which drives the spiral blade to rotate, reducing the pressure inside the sampling cylinder. Under the action of the pressure difference, the liquid enters the sampling cylinder through the one-way valve.

[0010] Furthermore, the sampling component also includes a depth sensor, which is mounted on the sampling cylinder and is communicatively connected to the lifting mechanism. The depth sensor can detect the depth of the sampling component and feed the depth back to the lifting mechanism, thereby facilitating sampling at the required depth.

[0011] Furthermore, the sampling component also includes a self-sealing membrane disposed at the communication port. The infusion mechanism includes a second liquid pump, a needle for connecting the measuring component and the communication port, and a drainage tube. The second liquid pump and the needle are both disposed on the measuring component, with the tip of the needle facing the self-sealing membrane and the blunt end of the needle communicating with the measuring component. The two ends of the drainage tube are respectively connected to the communication port and the inside of the sampling cylinder. By setting the self-sealing membrane, liquid is prevented from flowing out of the communication port. After sampling is completed, the lifting mechanism is activated in reverse to retract the sampling component. After retraction, the needle punctures the self-sealing membrane and connects the measuring component with the liquid sample inside the sampling cylinder through the drainage tube. At this time, the second liquid pump is activated, and the sample enters the measuring component through the drainage tube and the needle.

[0012] Furthermore, the measuring component is provided with a first positioning element, and the sampling cylinder is provided with a second positioning element that cooperates with the first positioning element. By setting the first and second positioning elements, the position of the sampling cylinder relative to the resetting position of the measuring component is positioned, thereby facilitating the needle to puncture the self-sealing membrane during resetting.

[0013] Furthermore, the measuring component includes a housing, a measuring cylinder, a mud level sensor, a control panel, an observation window, and a camera. The measuring cylinder is housed inside the housing, the mud level sensor is mounted on the measuring cylinder, and the control panel, the observation window, and the camera are all mounted on the housing. The mud level sensor and the camera are both electrically connected to the control panel. The lifting mechanism is mounted on the housing, and both ends of the infusion mechanism are connected to the measuring cylinder and the sampling component, respectively. After the sample enters the measuring cylinder, it is allowed to stand. After standing, the mud level sensor is used for measurement. During measurement, the internal condition of the measuring cylinder can be observed through the observation window. Simultaneously, the control panel controls the camera to take pictures and record the data after measurement. The data from the mud level sensor and the camera are stored in the control panel for later retrieval.

[0014] Furthermore, the system also includes a cleaning unit for cleaning the graduated cylinder, which is located inside the outer casing. The graduated cylinder has a vent. After the measurement is completed, the vent is opened to discharge the sample, and the cleaning unit is activated to clean the graduated cylinder for the next measurement.

[0015] Furthermore, the measuring cylinder has an opening at the top, and a telescopic sealing cap for sealing the opening is provided between the cleaning component and the measuring cylinder. After the telescopic sealing cap is activated to seal the opening, the second liquid pump is activated to draw the sample into the measuring cylinder; when cleaning is completed, the telescopic sealing cap is activated in reverse to open the opening, and the cleaning component cleans the measuring cylinder through the opening.

[0016] Furthermore, the cleaning component includes a telescopic rotating mechanism, a spray head, and a test tube brush head. The telescopic rotating mechanism is mounted on the outer casing. Both the spray head and the test tube brush head are connected to the output end of the telescopic rotating mechanism, and both the telescopic rotating mechanism and the spray head are electrically connected to the control panel. Activating the telescopic rotating mechanism moves the test tube brush head towards the inside of the measuring cylinder, while the spray head sprays cleaning solution into the measuring cylinder, and the test tube brush head cleans the measuring cylinder.

[0028] Example 1

[0029] This embodiment is the first embodiment of an intelligent sludge settling ratio measuring device, such as... Figure 1 As shown, the device includes a measuring component 100, a sampling component 200, a lifting mechanism 300, and an infusion mechanism 400. The lifting mechanism 300 is mounted on the measuring component 100, and the sampling component 200 is connected to the output end of the lifting mechanism 300. The lifting mechanism 300 uses an existing mechanism capable of lifting in the prior art. In this embodiment, as shown... Figure 1 As shown, the lifting mechanism 300 can be configured as a lifting motor and a lifting wire rope. The lifting motor is mounted on the measuring component 100. The two ends of the lifting wire rope are connected to the lifting motor and the sampling component 200, respectively. The position of the sampling component 200 in the submerged water body can be adjusted according to the actual water depth. The two ends of the infusion mechanism 400 are connected to the measuring component 100 and the sampling component 200, respectively.

[0030] like Figure 3As shown, the measuring component 100 includes a housing 110, a measuring cylinder 120, a sludge level sensor 130, a control panel 140, an observation window 150, and a camera 160. The measuring cylinder 120 is housed inside the housing 110 and has a capacity of 1000 mL. The outer wall of the measuring cylinder 120 is engraved with corresponding graduations. The operator can read the measurement results through the observation window 150. Specifically, the measuring cylinder is made of tempered borosilicate glass to improve the component's strength, hardness, chemical stability, and light transmittance. The sludge level sensor 130 is located on the measuring cylinder 120. The sludge level sensor 130 detects changes in the electrode or pressure difference as the liquid level in the measuring cylinder 120 moves up and down, and converts these signals into a sludge settling ratio value. The control panel 140, observation window 150, and camera 160 are all located on the housing 110. The observation window 150 can be located on the outer wall. On opposite sides of the shell 110, light strips may be provided around the outer ring of the observation window 150 to facilitate the operator's observation of the internal situation. The camera 160 is a miniature camera. Both the mud level sensor 130 and the camera 160 are electrically connected to the control panel 140. The control panel 140 has digital circuit control function and can calculate the measurement time and control the start and stop time of the equipment through the built-in program controller to realize the timed operation of the entire measuring device. The lifting mechanism 300 is located on the shell 110. The two ends of the infusion mechanism 400 are connected to the measuring cylinder 120 and the sampling component 200, respectively. After the sample enters the measuring cylinder 120, it is allowed to stand. After standing, the sample is measured by the mud level sensor 130. During the measurement, the internal condition of the measuring cylinder 120 can be observed through the observation window 150. At the same time, the camera 160 is controlled by the control panel 140 to take pictures and record the data after the measurement. The data from the mud level sensor 130 and the camera 160 are stored in the control panel 140 for easy retrieval later. In other words, the control panel 140 is deployed in a local area network and can be connected to the smart water purification platform equipment through the API interface of the cloud platform to complete remote control operation, as well as the storage and sharing of photos and data, reducing the workload of on-duty personnel and improving work efficiency and the accuracy of measurement data.

[0031] like Figure 2As shown, the sampling component 200 includes a sampling cylinder 210, a one-way valve 220, and a first liquid pump 230. The sampling cylinder 210 can hold 1200 mL of mixed liquid. The sampling cylinder 210 has an inlet 211 and a connecting port 212. The inlet 211 is located at the bottom of the sampling cylinder 210, and the connecting port 212 is located at the top of the sampling cylinder 210. The sampling cylinder 210 may also have an exhaust port for venting air. The one-way valve 220 is located at the inlet 211. The one-way valve 220 may be an embedded spring check valve. The first liquid pump 230 is located at the inlet 211. The two ends of the infusion mechanism 400 are connected to the measuring component 100 and the connecting port 212, respectively. After the sampling component 200 reaches the required sampling height, the first liquid pump 230 is activated. The first liquid pump 230 draws liquid through the one-way valve 220 at the inlet 211 into the sampling cylinder 210. When the first liquid pump 230 is not set, the sampling component 200 can be submerged in the lower position of the biochemical tank. When the external pressure is greater than the internal pressure, the one-way valve 220 will automatically lift up to inject water. After leaving the water surface, the internal pressure will be greater than the external pressure and the valve will automatically close.

[0032] like Figure 2 As shown, the first liquid pump 230 is an impeller pump, comprising a waterproof motor 231 and a spiral blade 232. The waterproof motor 231 is located inside the sampling cylinder 210, and the spiral blade 232 is connected to the output end of the waterproof motor 231. After the sampling component 200 reaches the required sampling height, the waterproof motor 231 is activated, driving the spiral blade 232 to rotate, reducing the internal pressure of the sampling cylinder 210. Under the action of the pressure difference, the liquid enters the sampling cylinder 210 through the one-way valve 220. This combines the principles of a centrifugal pump and a vortex generator, utilizing negative pressure swirling to draw in the sample. The spiral blade 232 is used to stir the sample, ensuring the uniformity of the sampled mixture and improving the safety of the equipment.

[0033] like Figure 2 As shown, the sampling component 200 also includes a depth sensor 250, which is mounted on the sampling cylinder 210 and is communicatively connected to the lifting mechanism 300. The depth sensor 250 can detect the depth of the sampling component 200 and feed the depth back to the lifting mechanism 300, thereby facilitating sampling at the required depth and adjusting the submersion depth of the sampling component 200 according to the actual water depth of the biological treatment tank.

[0034] The working principle of the intelligent sludge settling ratio measuring device in this embodiment is as follows:

[0035] When determining the sludge settling ratio, the lifting mechanism 300 is activated to lower the sampling component 200 to the required sampling height within the biological treatment tank. The sampling component 200 then collects the sample. After sampling, the infusion mechanism 400 is activated to infuse the sample into the measuring component 100 for sludge settling ratio determination. The lifting mechanism 300 allows the sampling component 200 to be lowered to the required sampling height, and the infusion mechanism 400 infuses the sample into the measuring component 100 for sludge settling ratio determination. This method is simple to operate and facilitates the determination of the sludge settling ratio.

[0036] Example 2

[0037] This embodiment is the second embodiment of the intelligent sludge settling ratio measuring device. This embodiment is similar to the first embodiment, except that, as shown in the example... Figure 2 and Figure 3 As shown, the sampling component 200 also includes a self-sealing membrane 240, which is located at the connecting port 212. The self-sealing membrane 240 is a three-layer silicone composite membrane that can self-close to prevent leakage when not connected. The infusion mechanism 400 includes a second liquid pump 410, a needle 420 for connecting the measuring component 100 and the connecting port 212, and a drainage tube 430. The second liquid pump 410 and the needle 420 are both located on the measuring component 100. The tip of the needle 420 faces the self-sealing membrane 240, and the blunt end of the needle 420 is connected to the measuring component 100. The needle 420 is a ceramic needle. This device is used in the biochemical tank of a conventional municipal sewage treatment plant. The diameter of the ceramic needle is about 4 mm. In actual use, a ceramic needle of appropriate diameter can be selected according to the actual situation to avoid damaging the sample. The two ends of the drainage tube 430 are connected to the connecting port 212 and the inside of the sampling tube 210, respectively. The drainage tube 430 is fixed to the inner wall of the sampling component 200. By setting a self-sealing membrane 240 to prevent liquid from flowing out of the connecting port 212, after sampling is completed, the lifting mechanism 300 is activated in reverse to retract the sampling component 200. After retraction, the needle 420 punctures the self-sealing membrane 240 and connects the measuring component 100 with the liquid sample inside the sampling cylinder 210 through the drainage tube 430. At this time, the second liquid pump 410 is activated, and the sample enters the measuring component 100 through the drainage tube 430 and the needle 420. The second liquid pump 410 can be set as a vacuum pump.

[0038] In this embodiment, the lifting mechanism 300 is detachably connected to the sampling cylinder 210, and the sampling component 200 can be completely disassembled and maintained after long-term use.

[0039] like Figures 1 to 4As shown, the measuring component 100 is provided with a first positioning element 111, and the sampling cylinder 210 is provided with a second positioning element 213 that cooperates with the first positioning element 111. By setting the first positioning element 111 and the second positioning element 213, the position of the sampling cylinder 210 relative to the measuring component 100 during reset is positioned, thereby facilitating the needle 420 to puncture the self-sealing membrane 240 during reset.

[0040] Specifically, in this embodiment, the first positioning element 111 is a ring electromagnet, and the second positioning element 213 is a ring-shaped mating magnet. When released, the ring electromagnet is de-energized, the first positioning element 111 and the second positioning element 213 separate, and the sampling cylinder 210 enters the biochemical pool. When reset, the ring electromagnet is energized, and the ring electromagnet and the ring-shaped mating magnet are positioned and connected. At the same time, a conical guide groove is provided on the self-sealing membrane 240, and the piercing needle 420 pierces the self-sealing membrane 240 under the guidance of the conical guide groove.

[0041] Example 3

[0042] This embodiment is the third embodiment of the intelligent sludge settling ratio measuring device. This embodiment is similar to embodiment one, except that, as Figure 1 and Figure 4 As shown, the system also includes a cleaning component 500 for cleaning the measuring cylinder 120. The cleaning component 500 is located inside the housing 110. The measuring cylinder 120 has a vent 121, which is controlled by a solenoid valve that can be electrically connected to the control panel 140. After the measurement is completed, the vent 121 is opened to discharge the sample, and the cleaning component 500 is activated to clean the measuring cylinder 120 for the next measurement.

[0043] The measuring cylinder 120 has an opening 122 at the top. A telescopic sealing cap 123 for sealing the opening 122 is provided between the cleaning component 500 and the measuring cylinder 120. The telescopic sealing cap 123 and the second liquid pump 410 can both be electrically connected to the control panel 140. When the telescopic sealing cap 123 closes the opening 122, the control panel 140 controls the second liquid pump 410 to start. After the telescopic sealing cap 123 is activated to seal the opening 122, a sealed environment is formed in the measuring cylinder 120. The second liquid pump 410 is then activated to draw the sample into the measuring cylinder 120. When cleaning is required after measurement, the telescopic sealing cap 123 is activated in reverse to open the opening 122, and the cleaning component 500 cleans the measuring cylinder 120 through the opening 122.

[0044] Specifically, the telescopic sealing cover 123 includes a telescopic mechanism and a sealing cover. The telescopic mechanism is located inside the housing 110, and the sealing cover is connected to the output end of the telescopic mechanism. The size of the sealing cover matches that of the opening 122.

[0045] The cleaning component 500 includes a telescopic rotation mechanism 510, a spray head 520, and a test tube brush head 530. The telescopic rotation mechanism 510 is mounted on the housing 110 and includes a telescopic mechanism and a rotation mechanism. Both the telescopic and rotation mechanisms utilize existing technologies, such as a cylinder for the telescopic mechanism and a rotary motor for the rotation mechanism. The spray head 520 and the test tube brush head 530 are both connected to the output end of the telescopic rotation mechanism 510. Specifically, the spray head 520 and the test tube brush head 530 are detachably connected to the output end of the telescopic rotation mechanism 510 for easy maintenance and replacement. Both the telescopic rotation mechanism 510 and the spray head 520 are electrically connected to the control panel 140. Activating the telescopic rotation mechanism 510 moves the test tube brush head 530 into the measuring cylinder 120, while the spray head 520 sprays cleaning fluid into the measuring cylinder 120, and the test tube brush head 530 cleans the measuring cylinder 120.

[0046] The cleaning component 500 may also include a cleaning water tank, which is mounted on the housing 110 and is connected to the spray head 520. The cleaning water tank has an inlet pipe that is connected to an external cleaning water source, and an inlet valve is provided on the inlet pipe.

[0047] In this embodiment, the diving depth of the sampling component 200 and the equipment operating time are set according to the average liquid level of the biochemical tank and the required measurement cycle. After the measuring device enters the measurement mode according to the set time, the lifting mechanism 300 lowers the sampling component 200 to the set depth, the one-way valve 220 of the bottom liquid inlet 211 is opened, and the impeller pump is started to achieve the purpose of uniform mixing of mud and water for sampling in a vortex manner. After 1200 mL of mixed liquid is drawn into the inner cavity of the sampling component 200, the lifting mechanism 300 rises back, and the measuring component 100 and the sampling component 200 are positioned and connected by a magnetic ring. Then, the ceramic needle at the bottom of the measuring component 100 penetrates the self-sealing membrane 240 at the top of the sampling component 200, and at the same time, the telescopic sealing cover 123 is closed and the second liquid pump 410 is started to transfer 1000 mL of mixed liquid into the measuring cylinder 120. During this period, the spiral blade 232 keeps rotating at a low speed to ensure that the mud and water mixture remains in a uniform state. After the mixture in the measuring cylinder 120 has been allowed to stand for 30 minutes, the sludge level sensor 130 detects the sludge-water interface within the measuring cylinder 120 and converts the signal into a digital signal corresponding to the sludge settling ratio. Simultaneously, a miniature camera automatically captures images of the measuring cylinder 120, and all data and photos are automatically uploaded to the cloud. After the measurement is completed, the mixture in the measuring cylinder 120 is discharged into the biological treatment tank through the drain port 121. Next, the water inlet valve of the cleaning component 500 is opened, and the spray head 520 and the test tube brush head 530 extend, retract, and rotate within the measuring cylinder 120 to effectively clean it, maintaining its clarity. The cleaning waste liquid is discharged through the drain port 121.

Its integrated design of stirring, sampling, measurement, and cleaning greatly simplifies the workflow for measuring sludge settling ratio in the daily operation of wastewater treatment plants, improving measurement accuracy and work efficiency while reducing operational risks.
