Description

Technical Field

[0001] This utility model belongs to the technical field of wet dust collectors, specifically relating to an automatic sludge-removing circulating water tank. Background Technology

[0002] In the field of wet scrubber technology, the circulating water tank is one of the core supporting equipment. Its core function is to provide circulating spray water for the dust collector and to temporarily store and filter the dust-laden wastewater after spraying, so as to realize the reuse of water resources and reduce the water consumption cost of wet scrubber process.

[0003] Traditional wet scrubbers are all modular structures, such as those using low-temperature evaporation, pressure filtration, and screw extrusion technologies. None of these technologies can be used for online, real-time circulating spraying of wet scrubbers. Secondly, circulating water tanks mostly rely on fixed filter screens or filter layers to intercept and filter dust-laden wastewater. However, dust and flocculent impurities in the wastewater easily accumulate on the surface of the filter layer, forming residue. This accumulated residue can clog the filter pores, leading to increased filtration resistance, a significant decrease in wastewater filtration efficiency, and ultimately, a reduction in dust removal performance.

[0004] Therefore, an automatic sludge-removing circulating water tank was designed to overcome the aforementioned technical shortcomings. Utility Model Content

[0023] This specific embodiment is an automatic sludge-removing circulating water tank, and its structural schematic diagram is as follows. Figures 1-5 As shown, the device includes a housing 1. A water inlet pipe 2 is fixedly connected to the top surface of the housing 1 near the left side. A drain pipe 3 is fixedly connected to the right side wall of the housing 1 near the upper side. A support plate 18 is fixedly connected to the inner wall of the housing 1. A filter layer 4 is movably connected to the inner cavity of the housing 1 above the support plate 18. The filter layer 4 is preferably a combination of a filter screen and filter cotton. The filter cotton is filled below the filter screen. The filter screen is used to filter large particles of impurities, and the filter cotton is used to filter fine impurities such as dust. During rinsing, large particles are mainly rinsed to avoid clogging and affecting the flow of sewage. A traction component is provided on the side wall of the housing 1. A baffle 5 is fixedly connected to the top edge of the filter layer 4. A rinsing component is provided on the side wall of the baffle 5. A guide plate 6 is fixedly connected to the right side wall of the baffle 5. The guide plate 6 corresponds to the drain pipe 3.

[0024] like Figure 1 and Figure 4 As shown, the traction assembly includes a motor 10 fixedly installed on the right side wall of the housing 1. The output shaft of the motor 10 is fixedly connected to a grooved wheel 7. A steel wire 8 is wound and connected inside the grooved wheel 7. A through groove 9 is opened on the right side wall of the housing 1. One end of the steel wire 8 passes through the through groove 9 and is hinged to the top surface of the baffle 5 near the left side.

[0025] The motor 10 provides stable rotational power, which is converted into linear traction motion of the steel wire 8 through the grooved wheel 7. The grooved structure of the grooved wheel 7 can prevent the steel wire 8 from slipping and ensure power transmission efficiency. The steel wire 8 is made of high-strength stainless steel (default for industrial scenarios), which can withstand the weight of the filter layer 4 and residues. It is not easy to break after long-term use, solving the problem of easy wear of traditional rope traction. The through groove 9 provides a passage for the steel wire 8 to pass through, avoiding wear caused by direct friction between the steel wire 8 and the side wall of the box 1, and extending the service life of the component.

[0026] By controlling the forward and reverse rotation of the motor 10, the traction length of the steel wire 8 can be adjusted, thereby controlling the tilt angle of the filter layer 4 (e.g., tilting 15°-30°). When the amount of residue is small, a small tilt angle is sufficient to allow the residue to slide. When the amount of residue is large or stubborn, increasing the tilt angle can enhance the gravity sliding effect of the residue and prevent residue from accumulating. Compared with a tilt structure with a fixed angle, this design is suitable for dredging needs under different working conditions and improves the flexibility of the device.

[0027] In this design, the motor 10 is waterproof, and a waterproof shell can also be installed on the outside of the motor 10 to protect it. In addition, the front and rear side walls of the filter layer 4 are fixedly connected with pins near the right end face, and the other end of the pins is rotatably connected to the housing 1. Therefore, when the groove wheel 7 winds up the steel wire 8, it can drive the filter layer 4 to rotate around the pin, thereby tilting the filter layer 4.

[0028] In addition, the guide plate 6 is preferably made of flexible material. After the filter layer 4 is tilted, the guide plate 6 can abut against the inner wall of the drain pipe 3. During the rinsing process, it can play a guiding role and prevent some impurities from entering the filtered water through the gap between the filter layer 4 and the box 1.

[0029] like Figure 4 As shown, guide wheels 11 are rotatably connected to the upper and lower side walls of the through groove 9, and the steel wire 8 is located between the guide wheels 11. The diameter of the middle part of the guide wheel 11 is smaller than the diameter of the two ends, and a limiting and guiding space is formed between the two guide wheels 11. On the one hand, this can reduce the friction between the guide wheels and the steel wire 8, extend the service life of the steel wire 8, and on the other hand, prevent the steel wire 8 from shifting and falling off. The two guide wheels 11 are symmetrically arranged to form a clamping and limiting effect on the steel wire 8, which can prevent the steel wire 8 from shifting left and right during the traction process, ensure that the filter layer 4 is tilted in the preset direction, and avoid the problem that the filter layer 4 cannot be accurately guided into the drain pipe 3 due to the deviation of the steel wire 8.

[0030] like Figure 2 As shown, a valve 12 is installed on the side wall of the sewage pipe 3. The valve 12 can also be a solenoid valve, an electric valve, or other structures, used to control the opening and closing of the sewage pipe 3 and to regulate the flow rate. This is a mature existing technology and will not be described in detail in this solution.

[0031] like Figure 2 and Figure 5 As shown, the rinsing assembly includes a water pump 13 fixedly installed on the left side wall of the housing 1. A guide pipe 14 is fixedly connected to the inlet end of the water pump 13, and the other end of the guide pipe 14 communicates with the housing 1. A flexible hose 15 is fixedly connected to the outlet end of the water pump 13. A cavity 16 is formed inside the baffle 5 near the left side. Several rinsing holes 17 are formed on the inner left wall of the baffle 5. A through hole is formed on the left side wall of the housing 1. The other end of the flexible hose 15 passes through the through hole and communicates with the cavity 16. All rinsing holes 17 are inclined.

[0032] The water pump 13 directly draws circulating water from the tank 1 through the guide pipe 14 as the flushing water source, eliminating the need for additional fresh water and avoiding water waste caused by traditional external water source flushing, thus meeting industrial water conservation requirements. The wastewater containing residue after flushing is discharged through the drain pipe 3, without affecting the clean circulating water at the bottom of the tank 1. The design of the cavity 16 allows for even distribution of flushing water inside, ensuring consistent water pressure at each flushing hole 17 and preventing residue residue caused by insufficient local flushing pressure.

[0033] Specifically, the water pump 13 uses the purified water filtered inside the housing 1 to rinse the filter layer 4, realizing the recycling of water flow. During the rinsing process, some water flows through the filter layer 4 and re-enters the housing 1, reducing water waste. Secondly, the inclined structure of the rinsing hole 17 results in a radial water flow with different outlet positions, which can extend the rinsing range of the filter layer 4. At the same time, the radial water flow can efficiently rinse the filter holes, and impurities flow towards the guide plate 6 due to the impact of the water flow. The baffle 5 can also guide the flow, preventing impurities from entering the housing 1 from the edge of the filter layer 4, thus ensuring the quality of the purified water inside the housing 1.

[0034] Working principle: Dust and water mix and are discharged into the housing 1 through the inlet pipe 2. The filter layer 4 filters dust and flocculent impurities in the water. The filtered water drips onto the bottom of the housing 1 and can be used for water recycling. When too much dust and impurities accumulate on the surface of the filter layer 4, the water intake is stopped and the motor 10 is started. The output shaft of the motor 10 drives the groove wheel 7 to rotate. The groove wheel 7 winds up the steel wire 8, causing the other end of the steel wire 8 to pull the filter layer 4 to an inclined state. Then the water pump 13 is started. The water pump 13 draws clean water from inside the housing 1 through the guide pipe 14 and delivers it to the hose 15. The clean water fills the cavity 16 and is discharged from the flushing hole 17. The inclined setting of the flushing hole 17 increases the flushing surface of the filter layer 4. Impurities are impacted by the water flow and flow towards the guide plate 6. Some water and impurities are discharged through the drain pipe 3, and the other part of the water permeates the filter layer 4 and flows back into the housing 1 for recycling.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
