Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for detecting the viscosity of wastewater samples. Background Technology

[0002] To reduce the subsequent disposal costs of sludge, the moisture content of the treated sludge should be controlled below 60%. Concentrating and conditioning the sludge before dewatering can effectively change its particle properties, enhance dewatering performance, and reduce the moisture content of the sludge cake, thereby significantly reducing subsequent disposal costs.

[0003] Current sludge treatment pond dewatering systems mainly rely on the manual addition of chemical agents such as flocculants, coagulants, and dewatering agents. These agents alter the three-dimensional structure of the colloidal surface in the suspension and are then agitated by external forces such as stirring to cause the sludge particles to flocculate and settle.

[0004] In the existing technology, when preparing the reagent, it is necessary to take a wastewater sample, add the reagent to the water sample according to the process requirements, mix and stir for a certain time and rate, and then test the viscosity of the water sample to verify and adjust the reagent dosing effect.

[0005] However, the problem with the existing technology is that the testing process relies on manual handling of the water sample at each stage. For example, after stirring for several minutes, the water sample is transferred to the viscometer for testing for several more minutes. This requires staff to calculate the time required to operate between multiple devices, otherwise there will be waiting time or wasted efficiency due to idle equipment.

[0006] Therefore, if an automated auxiliary device for detecting the viscosity of wastewater samples can be designed based on the working conditions of the detection process, manual handling can be eliminated, thus improving detection efficiency. Utility Model Content

[0007] To address the shortcomings of the aforementioned technologies, this invention provides a viscosity detection device for wastewater samples.

[0008] The technical solution of this utility model is as follows: A viscosity testing device for wastewater samples includes a lifting drive mechanism, a lifting platform, a turntable drive mechanism, a rotating disk, a test container, a digital viscometer, a stirrer, and a PLC controller. The lifting drive mechanism is linked with the lifting platform, which has an installation position. The test container is placed at the installation position. The rotating disk is positioned vertically above the lifting platform, and several operating positions are spaced around its center on the rotating disk. The digital viscometer and the stirrer are fixed at each operating position and face the installation position. The turntable drive mechanism is linked with the rotating disk and drives the rotating disk to rotate forward and backward through the installation position. The PLC controller is signal-linked with the lifting drive mechanism, the turntable drive mechanism, the digital viscometer, and the stirrer, driving the test container to lift and engage / disengage with the components at the operating positions, and driving the rotating disk to rotate forward and backward to switch operating positions.

[0009] A further feature of this invention is that the device also includes a liquid extraction mechanism, which includes a first rotating platform, a platform driving mechanism, a first pump body, and a liquid extraction pipe. A plurality of storage containers are evenly distributed on the rotating platform. The platform driving mechanism includes a frame, a drive motor, and a transmission assembly. The drive motor, transmission assembly, and the first rotating platform work together to drive the storage containers to rotate. The liquid extraction pipe is connected to the first pump body and includes a first inlet and a first outlet. The first inlet extends to an operating position on the rotating disk. The first outlet is fixed to the frame and located vertically above the storage container's rotation path. The drive motor and the first pump body are both linked to a PLC controller signal to extract water samples from the test container into each storage container.

[0010] Using the above technical solution, after the digital viscometer completes the test, the water sample in the test container is extracted and stored separately for the next water sample test.

[0011] A further feature of this invention is that the device also includes an infusion mechanism, which comprises several test containers, a second pump body, and a collection pipeline. The test containers are provided with a second inlet and a second outlet. The second outlet is provided with an electrically controlled valve and a water outlet pipeline. The water outlet pipelines of each test container are respectively connected to the collection pipeline. The second pump body is connected to the collection pipeline. The collection pipeline is provided with an infusion hose extending to one of the operating positions on the rotating disk. The second pump body and each electrically controlled valve are linked to the PLC controller signal to deliver the water sample from one of the test containers into the test container.

[0012] Using the above technical solution and with the above settings, the PLC controller controls the infusion mechanism to input a new water sample to be tested into the testing container after one test is completed.

[0013] A further feature of this invention is that the device also includes a cleaning mechanism, which comprises a clean water tank, a wastewater tank, a third pump body, and a fourth pump body. The clean water tank is equipped with an electromagnetic valve and a clean water pipeline, which extends to one of the operating positions on the rotary disc and is connected to the third pump body. The wastewater tank is equipped with an electromagnetic valve and a wastewater pipeline, which extends to one of the operating positions on the rotary disc and is connected to the fourth pump body. The PLC controller is linked with the electromagnetic valve, the third pump body, and the fourth pump body to deliver clean water to the test container and extract wastewater from the test container.

[0014] Using the above technical solution, after a test is completed, clean water is injected into the container under test through a cleaning mechanism for cleaning. A stirrer can also be used to enhance the cleaning effect. Then, the wastewater is pumped out to a wastewater tank or drainage ditch.

[0015] A further feature of this invention is that the lifting platform is radially provided with two sets of clamping mechanisms on both sides of the installation position. Each clamping mechanism includes a track component, a slider, and a spring. The track component is provided with a sliding groove that matches the contour of the slider. The slider slides into the sliding groove. The spring is compressed between the slider and the sliding groove, driving the slider to move toward the side of the measuring container and abut against the outer circumferential surface of the measuring container.

[0016] By adopting the above technical solution, the position of the slider and the clamping force of the spring can be used to adapt to and clamp containers of different diameters.

[0017] A further feature of this invention is that an arc-shaped silicone pad is provided at the end of the slider facing the measuring container.

[0018] By adopting the above technical solution, friction is increased and vibration is reduced, thereby enhancing the stability of the container during the lifting process.

[0019] Further features of this utility model: The lifting drive mechanism includes a lifting seat, a lead screw, a lead screw nut seat, and a lead screw motor. The lead screw is arranged vertically and rotates with the lifting seat. The lifting seat is provided with a guide rail in the vertical direction. The lifting platform is fixedly connected to the lead screw nut seat and is provided with a guide groove adapted to the guide rail. The lead screw motor is linked with the lead screw and drives the lead screw nut seat to rise and fall along the lead screw. The turntable drive mechanism includes a first frame, a first drive motor, and a transmission assembly. The turntable rotates with the first frame and is linked with the first drive motor and the transmission assembly. The first drive motor is linked with the PLC controller signal to switch between different operating positions and align with the installation position.

[0020] The beneficial effects of this utility model are as follows: Through the structural design and coordination of the lifting drive mechanism, lifting platform, turntable drive mechanism, rotating disk, test container, digital viscometer, stirrer and PLC controller, it assists the staff in conducting viscosity testing. During the process, once the stirring is completed, it automatically enters the viscosity testing environment, eliminating the time that the staff have to wait by the equipment and the downtime, thus improving the efficiency between testing steps.

[0021] Specifically, through the coordinated operation of the lifting drive mechanism and the turntable drive mechanism, when the measuring container rises, it engages with the components at the operating station that are aligned at this time. That is, the stirrer, digital viscometer, or other components that need to detect the object can be inserted into the measuring container. Then, the components at the operating station are controlled to start and stop by the PLC controller. For example, the stirrer runs to stir the water sample in the measuring container, and the digital viscometer starts to detect the water sample in the measuring container.

[0022] Based on the testing process requirements, a PLC program is set to control the start and stop times of each component. For example, the agitator stops after running for 30 minutes. At this time, the lifting drive mechanism drives the test container to descend, disengaging it from the component at the operating station. Then, the turntable drive mechanism drives the rotating disc to rotate to the required angle, switching to the operating station for alignment with the installation position. For example, the agitator is switched to a digital viscometer. Then, the test container rises again, and the installation program proceeds to the next testing operation. Based on the technical concept of this application, the equipment on the drive panel can be set and switched according to the conventional wastewater testing requirements.

[0023] Further improvements included the design of a coordinated pumping mechanism, a delivery mechanism, and a cleaning mechanism to automatically extract the tested water sample, clean the testing container, and replenish the sample with a new one, thus enhancing the equipment's automation capabilities.

[0024] The clamping mechanism is designed to accommodate containers of different diameters, enhancing their stability during lifting and lowering. These containers are typically beakers or other commonly used testing and experimental equipment. Attached Figure Description
