Description

Technical Field

[0001] The utility model belongs to the technical field of mud suction machines, and in particular relates to a mobile mud suction machine. Background Art

[0002] Horizontal flow sedimentation tanks are widely used in large and medium-sized water plants and can be broadly divided into an inlet area, a sedimentation area, and a sludge area. Raw water, after being dosed, mixed, and flocculated, flows into the inlet area and is evenly distributed through perforated walls to the sedimentation area. The water in the sedimentation area flows horizontally, depositing flocculants into the sludge area. Sludge accumulates and concentrates at the bottom of the tank, requiring regular discharge. Sludge discharge methods include bucket bottom discharge, sludge scraper discharge, siphon discharge, or sludge suction pump discharge.

[0003] The dosage of flocculant is usually set based on experience and data from previous debugging. Due to the lack of water quality feedback, dynamic adjustment of the dosage cannot be achieved.

[0004] Horizontal flow sedimentation tanks are typically rectangular in structure. To ensure adequate flocculent sedimentation, large and medium-sized water plants often have long design lengths, which can lead to variations in water quality across different areas. Furthermore, existing horizontal flow sedimentation tanks lack suitable locations for instrumentation. Utility Model Content

[0030] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0031] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0032] See also Figure 1-2 This embodiment provides a mobile sludge suction machine, including a working bridge 2, a control module 5, a sludge interface meter 9, a turbidity meter 10, and a wandering current meter 11. The control module 5, the sludge interface meter 9, the turbidity meter 10, and the wandering current meter 11 are all arranged on the working bridge 2.

[0033] The sludge interface meter 9 is used to measure the mud level at the bottom of the sedimentation tank in real time to understand the amount of flocculated mud. The sludge interface meter 9 includes a transmitter 13 and a sensor 15, which are connected by a cable.

[0034] Transmitter 13 is used for system power supply, system setup, probe operation, data display and storage, and data output. Transmitter 13 is typically equipped with a backlit graphical display that visually displays parameters such as sludge level and echo curve. Sensor 15 transmits ultrasonic signals and receives reflected signals to measure the sludge interface. Depending on the model and technology, sensor 15 can be a VT sensor, an ultrasonic level meter, or an ultrasonic sludge interface probe.

[0035] A support 14 is provided at the front end of the working bridge 2, the bottom of which extends downward into the sewage. The transmitter 13 is mounted on the working bridge 2, while the sensor 15 is mounted at the bottom end of the support 14. This ensures that the sensor 15 always detects the sludge thickness in the area in front of the working bridge 2 during its movement. Furthermore, as the working bridge 2 moves, the sensor 15 can detect sludge thickness in different areas.

[0036] The turbidity meter 10 is used to measure the turbidity of water in the sedimentation tank. For example, the turbidity meter 10 includes:

[0037] a light source, which transmits light through the water sample (which is collected by a sampling tube);

[0038] The detector receives the light scattered by the water sample and converts it into an electrical signal;

[0039] Optical systems, including lenses, filters, etc., are used to guide light and optimize measurement conditions.

[0040] Turbidity sensors determine turbidity by measuring the degree of light scattering in wastewater. When light passes through wastewater containing suspended particles, some of the light is scattered, and the intensity of the scattered light is proportional to the turbidity level. A detector converts the scattered light into an electrical signal, which is then processed by a signal processor and displayed on a display as the turbidity value.

[0041] The turbidity meter 10 can be installed in a similar manner to the sludge interface meter 9. For example, the main body of the turbidity meter 10 can be placed on the working bridge 2, with its sampling tube extending below the sewage. To ensure the stability of the sampling tube of the turbidity meter 10, a fixed bracket can be provided on the working bridge 2. This bracket extends downward into the sewage, and the sampling tube of the turbidity meter 10 is tied and connected to this bracket.

[0042] The galvanometer 11 is used to detect the amount of positive (negative) ions remaining in the water after the coagulant reacts with the raw water, and detects the streaming current signal through the electrode sensor. For example, the galvanometer 11 includes:

[0043] The electrode sensor is responsible for measuring the current generated by charged ions or particles in the water sample (collected through the sampling tube). The electrode sensor consists of a cylinder and a piston. The reciprocating motion of the piston disturbs the double layer of the colloidal particles, forming a streaming current.

[0044] The controller reads the flow current value detected by the electrode sensor and converts it into an intuitive display value. The controller can be configured with a PID control function to adjust the opening of the metering pump or dosing valve.

[0045] The installation method for the wandering current meter 11 can be similar to that of the sludge interface meter 9. For example, the main body of the wandering current meter 11 is mounted on the working bridge 2, with its sampling tube extending below the sewage. To ensure the stability of the sampling tube of the wandering current meter 11, a fixed bracket can be provided on the working bridge 2, and the sampling tube of the wandering current meter 11 can be connected to the fixed bracket.

[0046] The sludge interface meter 9, turbidity meter 10, and wandering current meter 11 are all electrically connected to the control module 5. The control module 5 is usually equipped with a wireless communication module, which can communicate with the plant control center through the wireless communication module. At the same time, the control module 5 can receive information feedback from the sludge interface meter 9, turbidity meter 10, and wandering current meter 11.

[0047] For example, when the sludge suction machine is running, the plant control center can communicate with the control module 5 of the mobile sludge scraper through the wireless communication module, receive the detection signals of the sludge interface meter 9, turbidity meter 10, wandering current meter 11 and other instruments in real time, and obtain the recommended operating instructions through the set program or intelligent dosing module algorithm. After confirmation by the professionals in the central control room, the operating instructions can be sent to the control module 5 and dosing device of the mobile sludge suction machine to realize the intelligent addition of flocculants and the automatic operation of the mobile sludge suction machine.

[0048] The suction machine can be operated manually or automatically / remotely. When operating manually, the operator presses the corresponding buttons on the control module 5 to start or stop the device. When operating automatically, a timer can be set, and the PLC programmable controller automatically discharges mud according to the set mud discharge cycle. The mud discharge cycle can be set to 8 hours, 16 hours, 24 hours, etc.

[0049] In summary, the sludge suction machine provided in this embodiment, wherein the control module 5 receives information feedback from the sludge interface meter 9, turbidity meter 10, and wandering current meter 11, can transmit this information to the plant-wide control center. This can directly reflect the reaction effect between the water purifier and the raw water, and the effect of the coagulant addition, thereby providing direct and beneficial data support for adjusting the flocculant dosage. Furthermore, each instrument is mounted on the working bridge 2, which prevents interference between the sludge suction machine and the detection instruments during movement. The instrument detection area moves with the working bridge, allowing water quality to be tested at different locations within the sedimentation tank.

[0050] Example 2

[0051] See also Figure 3 On the basis of Example 1, the mud suction machine provided in this embodiment also includes a mud suction system 4, which includes a mud scraper 401 and a mud discharge pipe 402. A bracket 3 is fixed to the bottom end of the working bridge 2, and the mud scraper 401 and the mud discharge pipe 402 are both fixed to the bracket 3.

[0052] The bottom end of the scraper 401 contacts the bottom surface of the tank body 7 , so that when the scraper 401 moves with the working bridge 2 , the sludge deposited on the bottom of the tank body 7 can be scraped up.

[0053] The bottom end of the mud discharge pipe 402 extends to the bottom of the tank body 7, and the top end of the mud discharge pipe 402 extends into the mud discharge channel 6. A mud suction submersible pump 403 for sucking sludge is provided on the mud discharge pipe 402. When the mud discharge pipe 402 moves with the working bridge 2, it can suck sludge from different positions at the bottom of the tank body 7 into the mud discharge channel 6.

[0054] The mud discharge channel 6 is fixed on the outer wall of the tank body 7 , and the mud discharge channel 6 is connected to a mud discharge pipe, which can discharge the sludge in the mud discharge channel 6 .

[0055] The bottom end of the mud discharge pipe 402 is connected to a trumpet-shaped mud suction port 404. The trumpet-shaped structure can expand the effective area of ​​the mud suction port 404.

[0056] See also Figure 4 Each mud suction port 404 is provided with a scraper 401 on both sides. And the scrapers 401 on both sides of the mud suction port 404 are provided with a guide structure 405, which can push the mud in front of the scraper 401 to the mud suction port 404.

[0057] For example, when the mud suction port 404 is located in the middle position and the scraper 401 is located on both sides of the mud suction port 404, a guide structure 405 is provided on the front end surface of the scraper 401. The guide structure 405 can be a triangular prism structure. The guide structure 405 is provided with an inclined surface extending from both sides to the middle, and the inclined surface gradually approaches the mud suction port 404. In this way, during the movement of the scraper 401, the sludge can be pushed to the middle mud suction port 404, thereby improving the mud suction efficiency of the mud suction port 404.

[0058] Example 3

[0059] See also Figure 5 On the basis of Example 2, the sludge suction machine provided in this embodiment further includes a driving walking system 1, which includes a track 101, a roller 102, and a motor 103. The roller 102 is rotatably installed on the working bridge 2. The roller 102 cooperates with the track 101, that is, the roller 102 can roll along the track 101. The motor 103 is installed on the working bridge 2, and the motor 103 is used to drive the roller 102 to rotate.

[0060] The power output end of the motor 103 can be fixed coaxially with the roller 102. By rotating the power output end of the motor 103, the roller 102 can be driven to roll.

[0061] The track 101 can be installed at the top of the side wall of the tank body 7 using pre-embedded parts. For example, the top of the side wall of the tank body 7 may be pre-embedded with pre-embedded parts, and the track 101 is secured to the pre-embedded parts via bolts, making installation and removal very convenient. The track 101 can be arranged along the length of the tank body 7. In this way, when the roller 102 rolls on the track 101, it can drive the working bridge 2 along the length of the tank body 7, drive the bracket 3 along the length of the tank body 7, and further drive the scraper 401 and the mud discharge pipe 402 along the length of the tank body 7.

[0062] The drive system 1 can include two sets of tracks 101 and two sets of rollers 102. The two sets of tracks 101 are respectively positioned at the top of two opposing side walls of the tank body 7, and the two sets of rollers 102 are respectively engaged with the two sets of tracks 101. For example, the two sets of tracks 101 are respectively positioned above the two long sides of the tank body 7, so that the working bridge 2 spans the width of the tank body 7. Correspondingly, two sets of motors 103 can be fixedly mounted on the working bridge 2, each of which is used to drive the two sets of rollers 102 to rotate. The two sets of rollers 102 must rotate synchronously to ensure stable movement of the working bridge 2.

[0063] In this embodiment, the control module 5, the sludge interface meter 9, the turbidity meter 10, the wandering current meter 11, the sludge suction submersible pump 403, and the motor 103 can all be powered by the busbar 104, and the structure is simple and stable.

[0064] In the present embodiment, one end of the working bridge 2 is provided with a pedal 8. The pedal 8 is used for the staff to get on and off the working bridge 2.
