Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater lifting device with a crushing function. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater through physical, chemical, and biological methods to meet the water quality requirements for discharge into a water body or for reuse. In urban wastewater discharge, wastewater in certain areas is difficult to flow into municipal drainage pipes by gravity, so wastewater lifting stations are needed to collect the wastewater and discharge it into the municipal sewage network.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN220309865U) discloses a sewage lifting device, comprising a housing. An inlet pipe is located on one side of the housing, and a drain pipe is located on the other side. The inlet and drain pipes penetrate both side walls of the housing and are fixedly connected to it. A processing mechanism is fixedly connected inside the housing. Through the design of the processing mechanism, a filter cartridge can filter and trap impurities in the sewage. When a moving plate is impacted by water flow, it moves and touches a first switch, activating a first motor that drives a rotating rod. Subsequently, a first blade and a second blade can cut and pulverize the impurities in the sewage. Only after pulverizing to a size smaller than the pore diameter on the filter cartridge can the impurities be discharged into the housing, ensuring thorough pulverization. Furthermore, the first and second blades can respectively pulverize impurities that sink to the bottom and float on the surface, ensuring pulverization quality.

[0004] Although the aforementioned patent utilizes a filter cartridge to trap impurities in wastewater and a motor-driven first and second blade to crush and cut the impurities, ensuring their diameter is smaller than the filter cartridge's aperture before removal, during use, the impact of the wastewater flowing in from the outside, coupled with the unpredictable nature of the impurities, often makes it difficult for the first and second blades to completely crush them. Furthermore, if waste materials such as plastic are encountered, they will become entangled on the rotating rod as the motor rotates, leading to motor overload or even motor burnout. Additionally, sludge and other impurities are difficult to cut by the blades due to water resistance, and prolonged use can easily cause clogging of the filter cartridge. This is detrimental to the long-term use of the device and to improving wastewater treatment efficiency.

[0005] Therefore, this utility model provides a sewage lifting device with a crushing function to solve the above problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a sewage lifting device with a crushing function, such as... Figures 1-6 As shown, the sewage lifting device with crushing function includes a housing 1, a plurality of support columns 101 connected to the bottom of the housing 1, a water inlet pipe 102 connected to the side wall of the housing 1, and a crushing component 2 installed inside the housing 1.

[0027] The crushing assembly 2 includes a support plate 201 connected to the outer wall of the housing 1. A drive motor 202 is connected to the top of the support plate 201. Multiple rotating sleeves 203 are connected to the outer wall of the housing 1 on one side of the drive motor 202. A crushing roller 204 is sleeved at the output end of the drive motor 202. The crushing roller 204 rotates inside one of the rotating sleeves 203. A crushing roller 205 that cooperates with the crushing roller 204 is rotatably connected to the inner wall of the rotating sleeve 203. A drive wheel 206 is sleeved on the side of the crushing roller 204 near the drive motor 202. A driven wheel 207 is sleeved on the outer wall of the crushing roller 205. The outer wall of the drive wheel 206 is connected to the driven wheel 207 via a synchronous belt 208. A circulation assembly 3 for improving the crushing effect is set inside the housing 1 below the crushing roller 204. A drive assembly 4 that provides power to the circulation assembly 3 is set on the side wall of the housing 1.

[0028] The circulation assembly 3 includes a circulation box 301 connected to the inner wall of the casing 1. A recycling box 302 is connected to the bottom of the casing 1. A one-way plate 303 is symmetrically rotatably connected to the inner wall of the recycling box 302. A reset spring strip 304 is connected to the bottom of the one-way plate 303. Multiple drainage holes 305 for drainage are opened at the bottom of the circulation box 301. A pneumatic telescopic rod 306 is connected to the inner side wall of the circulation box 301.

[0029] The drive assembly 4 includes a suction pump 401 connected to the side wall of the chassis 1, with the input end of the suction pump 401 located inside the recycling bin 302, and the output end of the suction pump 401 sleeved with a drain pipe 402, the end of which is connected to the outer wall of the water inlet pipe 102.

[0030] For example, the crushing component 2 ensures that the impurities in the water discharged from the sewage lifting station are reduced, preventing machine malfunctions caused by excessively large impurities. Sewage is discharged into the machine housing 1 through the inlet pipe 102. The drive motor 202 is started to rotate the crushing roller 204 at the output end, using its sharp outer wall agitator to cut the impurities in the sewage. Then, the synchronous belt 208 drives the two driven wheels 207 to rotate, which in turn drives the crushing roller 205 to rotate. Through the cooperation of the crushing roller 205 and the crushing roller 204, the impurities can be crushed and cut to the maximum extent, avoiding the phenomenon of impurities not being discharged. Then, the sewage flows into the circulation tank 301. Through the cooperation of the various components in the circulation component 3, the impurities with a particle size larger than the drain hole 305 are further circulated and crushed and cut again, minimizing the particle size of the impurities. When the sewage passes through the crushing roller 205, due to the weight of the crushing roller 205, it is further crushed and cut. After the force is applied, the sewage will be discharged carrying impurities with a particle size smaller than that of the drain hole 305. The larger impurities will slide into the recovery box 302 through the bottom of the inclined circulation box 301 due to gravity. Since the inner wall of the recovery box 302 is rotatably connected to the one-way plate 303, and the bottom of the one-way plate 303 is provided with a reset spring strip 304, when the accumulated weight is too large, the one-way plate 303 will rotate inward, causing the impurities to flow into the recovery box 302. Then, due to the elasticity, it will reset and close, and be sucked in by the suction pump 401 of the drive component 4. Then, it will be discharged into the water inlet pipe 102 through the sewage pipe 402, and flow into the crushing component 2 again to be crushed and cut. Through the cooperation of the crushing component 2, circulation component 3, and drive component 4, the particle size of impurities in the sewage can be reduced to the greatest extent, improving the sewage treatment efficiency and reducing the phenomenon of machine failure caused by excessive impurities.

[0031] The pneumatic telescopic rod 306 is fitted with a cleaning scraper 307 for scraping off solid residues at its end, and a brush 308 for cleaning the bottom of the circulation box 301 is connected to the bottom of the cleaning scraper 307.

[0032] Multiple filter plates 103 for further interception of impurities are connected to the bottom of the casing 1. A return box 104 is connected to the inner wall of the filter plates 103 at the bottom of the casing 1. A return pipe 105 is connected to the side wall of the return box 104, and the end of the return pipe 105 is connected to the input end of the suction pump 401.

[0033] A drain pump 106 is installed on the inner wall of the chassis 1, and a drain pipe 107 is connected to the side wall of the chassis 1. The output end of the drain pump 106 is connected to the end of the drain pipe 107.

[0034] For example, the pneumatic telescopic rod 306 drives the cleaning scraper 307 at the end to reciprocate, which can actively scrape away any impurities that have not fallen into the recycling bin 302 and make them fall into the recycling bin 302. This not only avoids the phenomenon of impurities clogging the drain hole 305, but also improves the drainage efficiency. The brush 308 can also clean the bottom of the circulation bin 301, further improving the drainage. The multiple filter plates 103 set at the bottom of the casing 1 have holes with diameters decreasing in the working direction, which will further intercept larger impurities and make them fall into the return box 104. The suction pump 401 will then draw them back from the return pipe 105 and crush them again, preventing excessive impurities from affecting the water output efficiency of the drainage pump 106.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
