For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figures 1 to 4 As shown, an embodiment of the present invention relates to a truss-type blowing scraper type mud scraper, including: a truss car for being erected on the top of a sedimentation tank and a guide rail 6 for being fixed on the top of the sedimentation tank; wherein, the truss car includes: a frame 1, a walking mechanism 2, a mud scraping device 3, a high-pressure water blowing device 4 and a lifting mechanism 5.

[0035] Specifically, Figure 1 and Figure 2 As shown, the carriage 1 is movably arranged on the guide rail 6; the walking mechanism 2 is arranged on the side of the carriage 1 facing the guide rail 6, that is, as shown in FIG. Figure 1 As shown, the walking mechanism 2 is arranged at the bottom of the frame 1. The walking mechanism 2 is used to drive the frame 1 to walk along the guide rail 6. The scraping device 3 and the high-pressure water blowing device 4 are both arranged on the frame 1 and extend into the sedimentation tank, so as to scrape the sedimentation tank with the cooperation of the two. The lifting mechanism 5 is arranged on the frame 1, and the lifting mechanism 5 is used to lift and lower the scraping device 3. In some embodiments, the lifting mechanism 5 can be a winch.

[0036] The truss-type blowing scraper-type mud scraper of the embodiment of the present invention can effectively remove the mud and sediment at the bottom of the sedimentation tank through the cooperation between the mud scraping device and the high-pressure water blowing device. The high-pressure water blowing device can pre-loosen or disperse the sludge with strong adhesion, provide better working conditions for the mud scraping device, and thus improve the cleaning efficiency. In addition, the traveling mechanism drives the traveling frame to move along the guide rail, and the lifting and lowering operation of the mud scraping device by the lifting mechanism is combined to realize the automatic operation of the equipment. This not only reduces manual intervention, but also improves the stability and reliability of the operation of the equipment. In addition, since the truss car can move along the guide rail, the mud scraping device can flexibly adjust its position according to the shape and size of the sedimentation tank, and is suitable for sedimentation tanks of different sizes and structures, thereby enhancing the scope of application of the equipment. In addition, the lifting mechanism can lift the mud scraping device, which is convenient for inspection, maintenance or replacement of the mud scraping device, or for scraping mud at different depths of the sedimentation tank, and also avoids unnecessary wear of the mud scraping device in a non-working state. The high-pressure water blowing device can perform preliminary treatment on the sludge before scraping, reduce the diffusion and flying of the sludge during the scraping process, and reduce the possibility of secondary pollution. Through efficient scraping and blowing functions, the cleaning frequency caused by sludge accumulation is reduced, the service life of the sedimentation tank is extended, and the operation and maintenance costs are reduced.

[0037] In summary, the truss-type blowing scraper scraper of the embodiment of the present invention not only improves the functionality and efficiency of the scraper, but also takes into account the flexibility, safety and economy of the equipment. It is an advanced equipment suitable for the field of modern sewage treatment.

[0038] For example, Figure 3 As shown, the travel mechanism 2 includes: a travel motor 21, a transmission mechanism and a wheel set 25. The travel motor 21 is arranged on the travel frame 1, and the wheel set 25 is movably arranged on the guide rail 6. The output shaft of the travel motor 21 is in transmission connection with the transmission mechanism, and the transmission mechanism is in transmission connection with the wheel set 25.

[0039] Specifically, Figure 3 As shown, the transmission mechanism may include a small sprocket 22, a chain 23 and a large sprocket group 24. The small sprocket 22 is in driving connection with the output shaft of the travel motor 21, the chain 23 is in driving connection with the small sprocket 22 and the large sprocket group 24 respectively, and the large sprocket group 24 is in driving connection with the wheel group 25.

[0040] The truss-type blowing and scraping blade type mud scraper of the embodiment of the present invention realizes effective transmission of power through the combination of the traveling motor, the small sprocket, the chain and the large sprocket group. The chain drive mode can ensure high transmission efficiency, reduce energy loss, and ensure that the frame moves smoothly along the guide rail. In addition, the chain drive system has a simple and compact structure, occupies a small space, and is easy to arrange in the limited space of the truss car. In addition, the chain drive has a strong bearing capacity and impact resistance, and can adapt to the uneven load or sudden conditions that may exist in the sedimentation tank environment. In addition, the small sprocket and the large sprocket group are connected by a chain, which can achieve a more accurate speed ratio control, thereby ensuring the movement stability of the wheel group. This helps to avoid the impact of vibration or impact generated during the movement of the frame on the mud scraping device. In addition, the various components in the chain drive system (such as sprockets, chains) are standardized parts, which are easy to purchase and replace. When maintenance is required, only the relevant components need to be disassembled for inspection and maintenance, which is easy to operate. Finally, by adjusting the tooth ratio of the sprocket, the speed and torque output of the wheel group can be flexibly changed to adapt to guide rails of different sizes or different work requirements. This design enhances the versatility and flexibility of the equipment.

[0041] For example, Figure 3 As shown, the transmission mechanism also includes a coupling 26 and a connecting shaft 27; the first end of the connecting shaft 27 is connected to the large sprocket set 24, and the second end of the connecting shaft 27 is connected to the wheel set 25 through the coupling 26.

[0042] For example, Figure 4 As shown, the high-pressure water blowing device 4 includes: a pump 41, a water inlet pipe 42, a water outlet pipe 44 and a nozzle 45. The pump 41 is fixed to the rack 1, and the nozzle 45 is used to be arranged at the bottom of the sedimentation tank. The water inlet of the water inlet pipe 42 is used to communicate with the sedimentation tank, and the water outlet of the water inlet pipe 42 is connected to the water inlet of the pump 41. The water inlet of the water outlet pipe 44 is connected to the water outlet of the pump 41, and the water outlet of the water outlet pipe 44 is connected to the nozzle 45. In some embodiments, the pump 41 can be a high-pressure slurry pump.

[0043] The truss-type purge scraper of the embodiment of the present invention, after the high-pressure water is pressurized by the pump, is sprayed to the bottom of the sedimentation tank through the outlet pipe and the nozzle, which can effectively disperse and loosen the deposited sludge. This high-pressure water flow design can significantly improve the cleaning effect of stubborn sludge and reduce the workload of the scraper device. In addition, the entire high-pressure water purge device is composed of a pump, a water inlet pipe, a water outlet pipe and a nozzle, with a clear and compact structure, which is easy to install and maintain. The connection method between the various components is clear, ensuring the stability and reliability of the system. In addition, the water inlet of the water inlet pipe is connected to the sedimentation tank, and the water in the sedimentation tank is directly used as a water source, avoiding the need for additional external water supply, realizing the recycling of water resources, and reducing operating costs. Finally, the nozzle is arranged at the bottom of the sedimentation tank, and the position or angle can be adjusted according to actual needs to cover different cleaning areas. At the same time, by adjusting the pressure and flow of the pump, it can adapt to different types of sludge deposition conditions, enhancing the applicability of the equipment.

[0044] For example, Figure 4 As shown, the water outlet pipe 44 includes a first vertical pipe, a second vertical pipe arranged at a relative interval to the first vertical pipe, and an inclined pipe respectively connecting the first vertical pipe and the second vertical pipe. The water inlet of the first vertical pipe is connected to the water outlet of the pump 41, and the water outlet of the second vertical pipe is connected to the nozzle 45.

[0045] The truss-type purge scraper of the embodiment of the present invention has a water outlet pipe composed of a first vertical pipe, a second vertical pipe and an inclined pipe. This structure can reasonably distribute the water flow path, ensure that the high-pressure water can be smoothly transmitted to the nozzle after being output from the pump, and avoid uneven water flow or pressure loss caused by unreasonable pipeline design. In addition, the inclined pipe connects the first vertical pipe and the second vertical pipe to form a smooth water flow channel, which reduces the turbulence and resistance of the water flow at the bend of the pipeline, thereby reducing the water pressure loss and ensuring the high-pressure injection effect of the nozzle. The first vertical pipe and the second vertical pipe are arranged at a relative interval, and combined with the inclined pipe to form a stable triangular structure, the mechanical strength and vibration resistance of the entire water outlet pipe are enhanced, and the equipment can remain stable during operation, avoiding loosening or damage of the pipeline due to vibration.

[0046] In some embodiments, the high-pressure water blowing device includes a plurality of the nozzles 45 , at least one of the nozzles 45 discharges water toward the side wall of the sedimentation tank, and the remaining nozzles 45 discharge water toward the bottom wall of the sedimentation tank.

[0047] For example, Figure 4 As shown, the high-pressure water blowing device 4 further includes: a filter 43 , and the filter 43 is arranged at the water inlet of the water inlet pipe 42 .

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
