Description

A flocculant monitoring device for sludge dewatering systems Technical Field

[0001] This utility model relates to the technical field of wastewater treatment auxiliary devices, and in particular to a flocculant monitoring device for a sludge dewatering system. Background Technology

[0002] As is well known, in the field of wastewater treatment, sludge dewatering systems are a crucial link in the entire wastewater treatment process. Their main purpose is to reduce the water content of sludge through a series of physical, chemical, and biological treatment methods, transforming it from a liquid to a solid or semi-solid state for easier subsequent transportation, disposal, and utilization. Among these methods, the precise dosing device for flocculants plays a vital role in the sludge dewatering system. During the sludge dewatering process, the proper addition of flocculants can significantly improve the dewatering effect. Flocculants can promote the aggregation of tiny particles in the sludge into larger flocs, increasing the particle size and density, thus making it easier for the sludge to undergo solid-liquid separation through mechanical or physical methods. Furthermore, the precise dosing device ensures that the flocculant is added to the sludge in the appropriate dosage and manner, avoiding the impact of excessive or insufficient flocculant addition on the dewatering effect, while also helping to reduce reagent costs.

[0003] The existing flocculant precision dosing device consists of a storage tank, delivery pipeline, metering pump, and control system. The staff first pours the mixed flocculant solution into the storage tank, and then the metering pump delivers the flocculant solution from the storage tank to the sewage tank. However, it has been found that when the flocculant solution in the storage tank is insufficient, the staff cannot detect and add more in time. They can only check the liquid level in the storage tank through periodic inspections, which reduces the convenience of the device and results in poor practicality. Summary of the Invention

[0021] As shown in Figures 1 to 4, the flocculant monitoring device for a sludge dewatering system of this utility model includes a sewage tank 1, a storage tank 2, and a dispensing device 3. The storage tank 2 is located at the top left end of the sewage tank 1, and the dispensing device 3 is located at the front end of the storage tank 2. It also includes an inlet pipe 4, two sets of floats 5, a connecting plate 6, two sets of connecting ropes 7, a pressure sensing module 8, a signal receiving and control module 9, a warning light module 10, a rebound mechanism, and a filtering mechanism. The storage tank 2 has a working chamber. The top front end of the working chamber of the storage tank 2 is connected to the top of the connecting plate 6 via the rebound mechanism. The bottom of the connecting plate 6 is evenly connected to the top of the two sets of connecting ropes 7, and the bottom of each set of connecting ropes 7 is connected to a set of floats 5. The storage tank 2 has a pressure sensing module 8 at the top front end of its working chamber.

The storage tank 2 also has a signal receiving and control module 9 at the top front end, and a warning light module 10 at the top of the signal receiving and control module 9. The storage tank 2 has a water inlet pipe 4 at the top rear end of its working chamber, and a filter mechanism is installed inside the water inlet pipe 4.

[0022] As a preferred embodiment of the above, the rebound mechanism includes two sets of slide rods 11, two sets of first sliders 12, two sets of connecting springs 13, two sets of sliding plates 14, and a hinge assembly. Two sets of first sliding grooves are evenly arranged at the front end of the top of the working cavity of the storage box 2, and each of the two sets of first sliding grooves is provided with a set of slide rods 11. The two sets of first sliders 12 are slidably connected to the corresponding first sliding groove of the working cavity of the storage box 2 via the slide rods 11.

The bottoms of the two sets of slide plates 14 are hinged to the top of the connecting plate 6 through a hinge assembly. When the liquid level in the storage tank gradually decreases, it will drive the float to fall. The float will drive the connecting plate to move downward through the connecting rope and be hinged through the hinge assembly, so that the slide plate drives the first slider to slide and begins to compress the connecting spring. This can buffer the impact force generated when the float moves up and down, ensure that the pressure sensing module accurately detects pressure changes, extend the service life of the device, and thus enhance its practicality.

[0023] As a preferred embodiment of the above, the filtration mechanism includes a filter cartridge 15, a filter screen 16, and a positioning component. The filter cartridge 15 is slidably fitted on the outside and the inside of the water inlet pipe 4, and the filter screen 16 is provided at the bottom of the inside of the filter cartridge 15. The top of the outside of the filter cartridge 15 is in close contact with the top of the water inlet pipe 4 through the positioning component. The filtration mechanism can effectively filter impurities in the flocculant solution entering the storage tank, prevent impurities from clogging the dispensing device or affecting the flocculation effect, and ensure the quality of the flocculant, thus enhancing its practicality.

[0024] As a preferred embodiment of the above, the hinge assembly includes four sets of support rods 17 and multiple sets of hinge seats 18.

This makes the connection between the slide plate and the connecting plate more flexible and ensures that the pressure sensing module accurately receives the pressure signal, thus enhancing its practicality.

[0025] As a preferred embodiment of the above, the positioning component includes an annular block 19, with the top of the outer side of the filter cartridge 15 connected to the inner side of the annular block 19, and the bottom of the annular block 19 and the top of the water inlet pipe 4 in close contact; the positioning component can ensure the stable position of the filter cartridge in the water inlet pipe, prevent the filter cartridge from shaking or falling off, and ensure the stability of the filtration effect, thus enhancing practicality.

[0026] As a preferred embodiment of the above embodiment, it further includes two sets of guide blocks 20. A set of second sliding grooves is provided at the left and right ends of the working cavity of the storage box 2, and one end of each set of guide blocks 20 is slidably connected to the set of second sliding grooves. The left and right ends of the connecting plate 6 are connected to the other ends of the guide blocks 20, respectively. This provides a guiding function for the up and down movement of the connecting plate, ensures the stability and straightness of the movement of the connecting plate, improves the detection accuracy of the pressure sensing module, and thus enhances its practicality.

[0027] As a preferred embodiment of the above, a sealing cap 21 is also included. The bottom of the sealing cap 21 is provided with a groove, and the inner wall of the groove of the sealing cap 21 and the top of the outer side of the water inlet pipe 4 are respectively provided with threaded ends. The groove of the sealing cap 21 is connected to the top of the outer side of the water inlet pipe 4 by the threaded ends. The sealing cap can prevent external dust and debris from entering the water inlet pipe and the storage tank, ensuring the cleanliness of the flocculant solution, and at the same time preventing the flocculant solution from evaporating or leaking, thus enhancing its practicality.

[0028] This invention relates to a flocculant monitoring device for a sludge dewatering system. During operation, the storage tank is filled with flocculant solution, and a float floats on the surface. A connecting rope pulls a connecting plate upwards, and the connecting plate applies pressure to a pressure sensing module via a rebound mechanism. The pressure sensing module converts the pressure signal into an electrical signal and transmits it to a signal receiving and control module. At this time, the warning light module is off. As the dispensing device adds the flocculant solution to the wastewater tank, the liquid level in the storage tank gradually decreases, causing the float to descend. The float, via the connecting rope, moves the connecting plate downwards. The plate is hinged to a hinge seat and a support rod, causing the sliding plate to slide along the first slider, and thus initiating the contact spring movement. As the pressure plate is compressed, the pressure on the pressure sensing module decreases. The pressure sensing module detects the pressure change in real time and transmits the changed pressure signal to the signal receiving and control module. After receiving the signal from the pressure sensing module, the signal receiving and control module compares it with a preset pressure threshold. When the pressure signal is lower than the preset minimum threshold, it sends a signal to the warning light module, which lights up to remind the staff to add flocculant solution in time. After seeing the warning light, the staff opens the sealing cover and adds flocculant solution into the storage tank through the filter cartridge inside the inlet pipe until the addition is complete. Before completing the above actions, the device is first moved to the position required by the user.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
