Description

Technical Field

[0001] This utility model relates to the field of sewage treatment, and in particular to a sewage lifting device for preventing blockage. Background Technology

[0002] Anti-clogging sewage lifting equipment is mainly used for sewage discharge in areas without natural drainage slope, such as basements and garages. It is widely used in residential and commercial buildings. Its core function is to collect domestic sewage or light wastewater and transport it to the municipal drainage network through mechanical lifting, while reducing the occurrence of blockage failures. Currently, the anti-clogging sewage lifting equipment on the market mainly consists of a water storage tank, a submersible sewage pump, a simple inlet filter screen, and conventional connecting pipes. It mainly intercepts large debris such as hair and food scraps through the inlet filter screen, combined with the anti-winding impeller design of the pump body base, in order to reduce pipe and pump blockage and ensure stable daily drainage. Existing anti-clogging sewage lifting equipment has significant limitations in long-term use: its anti-clogging methods are relatively simple and cannot comprehensively address the diverse debris in sewage, such as hair, fibers, and food residue. This simplistic approach easily leads to problems such as filter clogging and pump jamming, which in turn affects the normal drainage efficiency of the equipment and increases the burden of frequent cleaning and maintenance for users. Therefore, an anti-clogging sewage lifting device is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a sewage lifting device to prevent clogging, aiming to improve the problem of difficulty in comprehensively dealing with various debris such as hair, fibers, and food residue in sewage.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a sewage lifting device for preventing blockage, comprising a shell, a crushing mechanism inside the shell, two suction mechanisms on the rear side of the shell, a water outlet at the bottom of the shell, and a water conveying component outside the water outlet; The rolling mechanism includes two coarse rolling wheels, which are rotatably connected to the inner wall of the outer casing. The inner wall of the outer casing is rotatably connected to two fine rolling wheels, which mesh with each other.

[0005] As a further description of the above technical solution: The suction mechanism includes two water pumps, which are fixedly connected to the outer wall of the housing. The water pumps are fixedly connected to an inlet pipe at the end away from the housing, and the water pump output end is fixedly connected to the inner wall of the housing.

[0006] As a further description of the above technical solution: The water outlet is fixedly connected to the bottom of the outer casing. The water supply assembly includes a water outlet head section, which is fixedly connected to the outside of the water outlet. A filter screen is fixedly connected inside the water outlet head section. A first flange is fixedly connected to the end of the water outlet head section away from the water outlet. A second flange is detachably fixedly connected to the outside of the first flange by bolts. A middle water outlet section is fixedly connected to the outside of the second flange. A water outlet tail section is fixedly connected to the end of the middle water outlet section away from the water outlet head section.

[0007] As a further description of the above technical solution: A crushing mechanism is fixedly connected to the top of the outer shell.

[0008] As a further description of the above technical solution: The outer shell is fixedly connected to a frame, and the top is fixedly connected to a cover plate.

[0009] As a further description of the above technical solution: A first motor is fixedly connected to the outside of the housing, and a second motor is fixedly connected to the outside of the housing. The output end of the first motor is fixedly connected to the outside of the coarse grinding wheel through the housing, and the output end of the second motor is fixedly connected to the outside of the fine grinding wheel through the housing.

[0010] As a further description of the above technical solution: The outer shell is connected to the water outlet, and the water outlet is connected to the water outlet section.

[0011] This utility model has the following beneficial effects: 1. In this invention, after sewage is drawn in by the suction mechanism, the crushing mechanism first uses a coarse grinding wheel to initially crush large debris in the sewage, and then a meshing fine grinding wheel further refines the debris. Two motors drive the system independently to ensure thorough crushing. Simultaneously, the sewage flows completely through the crushing structure under its own gravity, preventing untreated debris from directly entering subsequent channels. Compared to traditional single anti-clogging methods, this solution improves the crushing effect from the source, significantly reducing the risk of clogging and ensuring smooth sewage transport.

[0012] 2. In this utility model, the water supply component of the equipment adopts a detachable flange connection. When the filter screen is clogged or the water supply component needs maintenance, it is not necessary to disassemble the entire equipment; only the flange needs to be removed for cleaning. The top cover of the outer shell is easy to open and inspect the internal crushing mechanism. The external frame ensures the stability of the equipment while not hindering maintenance operations. This design simplifies the maintenance process, reduces maintenance time, lowers user maintenance costs, and improves the ease of use of the equipment. Attached Figure Description

[0015] 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.

[0016] Reference Figures 1-4 An embodiment of this utility model is provided: a sewage lifting device for preventing blockage, including a shell 1, a crushing mechanism 2 is provided inside the shell 1, two suction mechanisms 3 are provided on the rear side of the shell 1, a water outlet 4 is provided at the bottom of the shell 1, and a water conveying component 5 is provided outside the water outlet 4. The outer shell 1 serves as the core load-bearing structure of the equipment, providing installation space for the internal crushing mechanism 2 and the bottom water outlet 4. At the same time, it draws in external sewage through the two suction mechanisms 3 on the rear side. After being processed by the crushing mechanism 2, the sewage enters the water conveying component 5 through the water outlet 4, ultimately completing the lifting and transportation of sewage. All components work together as a whole through the outer shell 1, ensuring a continuous sewage treatment process.

[0017] Reference Figures 1-4 The rolling mechanism 2 includes two coarse rolling wheels 10, which are rotatably connected to the inner wall of the outer casing 1. Two fine rolling wheels 11 are rotatably connected to the inner wall of the outer casing 1, and the two fine rolling wheels 11 mesh with each other. When wastewater enters the casing 1, it first comes into contact with two rotating coarse grinding wheels 10. The coarse grinding wheels 10 crush large pieces of debris in the wastewater by rotating, reducing the probability of large pieces of debris directly entering subsequent channels. Subsequently, the pre-treated wastewater flows to two meshing fine grinding wheels 11. The fine grinding wheels 11 further refine small pieces of debris that have not been completely crushed by the coarse grinding wheels 10 by meshing and rotating, crushing the debris to a size that is easier to pass through the pipe, reducing the risk of blockage from the source.

[0018] Reference Figures 1-4 The suction mechanism 3 includes two water pumps 7, which are fixedly connected to the outer wall of the housing 1. The end of the water pump 7 away from the housing 1 is fixedly connected to an inlet pipe 8, and the output end of the water pump 7 is fixedly connected to the inner wall of the housing 1. After the equipment is started, the two water pumps 7 operate synchronously to generate negative pressure suction, which draws sewage from the external sewage collection area through the water inlet pipe 8. The sewage drawn in is directly transported to the inside of the outer casing 1 through the output end of the water pump 7, providing a stable water flow source for subsequent compaction treatment. Setting up two water pumps 7 can avoid equipment shutdown due to the failure of a single water pump, while enhancing the sewage suction efficiency and adapting to the needs of multi-point sewage collection.

[0019] Reference Figures 1-4 The water outlet 4 is fixedly connected to the bottom of the outer shell 1. The water supply assembly 5 includes a water outlet head section 14, which is fixedly connected to the outside of the water outlet 4. A filter screen 16 is fixedly connected inside the water outlet head section 14. A first flange 15 is fixedly connected to the end of the water outlet head section 14 away from the water outlet 4. A second flange 17 is detachably fixedly connected to the outside of the first flange 15 by bolts. A middle water outlet section 18 is fixedly connected to the outside of the second flange 17. A water outlet tail section 19 is fixedly connected to the end of the middle water outlet section 18 away from the water outlet head section 14. Wastewater processed by the crushing mechanism 2 flows naturally into the bottom outlet channel 4 under the combined action of gravity and slight pressure inside the outer shell 1, and then is introduced into the first outlet section 14 of the water conveying assembly 5. The filter screen 16 inside the first outlet section 14 intercepts small debris in the wastewater that has not been completely crushed, preventing it from entering the subsequent pipes. The filtered wastewater passes through the middle outlet section 18 and the tail outlet section 19 in sequence, and is finally transported to the municipal drainage network. The detachable connection between the first flange 15 and the second flange 17 allows for quick disassembly and cleaning of the pipes when the filter screen 16 is clogged or when maintenance is required inside the water conveying assembly 5, ensuring long-term unobstructed water delivery.

[0020] Reference Figures 1-4 The top of the outer shell 1 is fixedly connected to a crushing mechanism 2; By fixing the crushing mechanism 2 to the top of the outer shell 1, the sewage can enter the outer shell 1 from the rear suction mechanism 3 and flow downward naturally by its own gravity. During the flow, it can pass through the coarse crushing wheel 10 and fine crushing wheel 11 of the crushing mechanism 2 without the need for additional power to guide the water flow path. This ensures that every part of the sewage can be crushed and treated, and prevents untreated debris from directly entering the outlet channel 4 due to water flow detour, further improving the anti-clogging effect.

[0021] Reference Figures 1-4 The outer shell 1 is fixedly connected to the frame 6, and the top of the outer shell 1 is fixedly connected to the cover plate 9; The frame 6 outside the outer shell 1 provides stable support for the entire equipment, which can offset the vibration generated by the water pump 7 and motor during the operation of the equipment, prevent the equipment from shifting position or loosening parts due to vibration, and also facilitate the overall installation and fixing of the equipment; the cover plate 9 on the top of the outer shell 1 can close the top opening of the outer shell 1, on the one hand, to prevent sewage from splashing out of the outer shell 1 due to crushing and water flow impact during the treatment process, and on the other hand, to prevent external dust and debris from falling into the interior of the outer shell 1, preventing external impurities from mixing with sewage and increasing the probability of blockage, while protecting the internal crushing mechanism 2 from external contamination.

[0022] Reference Figures 1-4 A first motor 12 is fixedly connected to the outside of the outer casing 1, and a second motor 13 is fixedly connected to the outside of the outer casing 1. The output end of the first motor 12 is fixedly connected to the outside of the coarse grinding wheel 10 through the outer casing 1, and the output end of the second motor 13 is fixedly connected to the outside of the fine grinding wheel 11 through the outer casing 1. The first motor 12 serves as the power source for the coarse grinding wheel 10. After starting, it transmits power to the coarse grinding wheel 10 through its output end, driving the two coarse grinding wheels 10 to rotate relative to each other, thus achieving initial crushing of large debris. The second motor 13 serves as the power source for the fine grinding wheel 11. After starting, it drives one of the fine grinding wheels 11 to rotate through its output end. Since the two fine grinding wheels 11 mesh with each other, the actively rotating fine grinding wheel 11 will drive the other fine grinding wheel 11 to rotate synchronously in the opposite direction, thereby achieving fine crushing of debris. The two motors are driven independently, and the speed can be adjusted according to the amount of debris in the sewage, ensuring the crushing effect while avoiding energy waste.

[0023] Reference Figures 1-4 The outer shell 1 is connected to the water outlet 4, and the water outlet 4 is connected to the water outlet head section 14. The connection between the outer shell 1 and the outlet channel 4 ensures that all the wastewater treated by crushing inside the outer shell 1 can flow into the outlet channel 4, avoiding the accumulation of wastewater inside the outer shell 1 and preventing debris in the residual wastewater from clumping after a long period of time, which could cause blockage inside the outer shell 1. The connection between the outlet channel 4 and the first water outlet section 14 allows the wastewater in the outlet channel 4 to seamlessly enter the water conveying component 5, forming a complete water flow channel from the outer shell 1 treatment to the outlet channel 4 diversion and the water conveying component 5 transportation. This ensures that there are no dead corners in the wastewater during the entire transportation process, further reducing the possibility of pipe blockage.

[0024] Working Principle: The frame 6 fixed to the outside of the outer casing 1 provides stable support to counteract the vibrations caused by the operation of the water pump 7 and the motor. The cover plate 9 fixed to the top of the outer casing 1 seals the top opening, preventing sewage from splashing out due to crushing and water flow impact, and also preventing external dust and debris from falling into and contaminating the internal components. Subsequently, the two water pumps 7 of the suction mechanism 3 operate synchronously to generate negative pressure suction, drawing sewage from the external sewage collection area through the water inlet pipe 8 at the end of the water pump 7 away from the outer casing 1. The sewage is then directly transported to the inside of the outer casing 1 through the output end of the water pump 7. The sewage entering the outer casing 1 flows downwards under its own gravity, first contacting the two rotating coarse grinding wheels 10 driven by the first motor 12 in the crushing mechanism 2 fixed to the top of the outer casing 1. The coarse grinding wheels 10 initially crush and break up large pieces of debris in the sewage. Then, the sewage flows to the two rotating and meshing fine grinding wheels 11 on the inner wall of the outer casing 1. The fine grinding wheels 11 are driven by the second motor 13 fixed to the outside of the outer casing 1 to rotate synchronously in the opposite direction, crushing and breaking up unfinished debris. The small debris completely crushed by the coarse grinding wheel 10 is further refined to a size that is easy to pass through the pipe. The sewage treated by the crushing mechanism 2 flows out through the bottom outlet 4 connected to the outer shell 1 under the combined action of gravity and slight pressure inside the outer shell 1. It then enters the water conveying assembly 5 connected to the outlet 4. It first flows through the first outlet section 14 fixed outside the outlet 4 in the water conveying assembly 5. The filter screen 16 inside the first outlet section 14 intercepts the small debris in the sewage that has not been completely crushed. The filtered sewage then enters the middle outlet section 18 through the connection structure of the first flange 15 and the second flange 17. Finally, it is transported to the municipal drainage network through the tail outlet section 19. The detachable design of the first flange 15 and the second flange 17 allows for quick disassembly and cleaning when the filter screen 16 is clogged or when the water conveying assembly 5 needs maintenance. The entire process achieves sewage suction, crushing treatment, filtration and transportation through the cooperation of various components, effectively reducing the risk of blockage and ensuring a smooth sewage lifting process.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
