Description

Technical Field

[0001] The utility model relates to the technical field of mud pumps, and more specifically, to an anti-clogging mud pump. Background Art

[0002] Mud pumps are mainly used to transport non-clean water media. During the process of extracting mud, the mud pumps may contain branches, weeds and other debris in the field. These debris are easy to adhere to the impeller of the mud pump, causing the impeller to get stuck and the mud pump to get blocked.

[0003] In order to prevent clogging, some mud pumps will set a protective mesh structure at the feed pipe of the mud pump to prevent weeds and other debris from entering the mud pump and causing clogging.

[0047] In summary, when the overall equipment is in use:

[0048] The motor 3 is started, and the turbine 2 can be driven to rotate by the motor 3, so that the feed pipe 4 is in a negative pressure state, thereby realizing the extraction of mud. The mud enters from the feed pipe 4, and then, under the action of the turbine 2, it is discharged from the discharge pipe 5 to the outside, thereby realizing the extraction operation of the mud;

[0049] During this process, the mud will first reach the protective cover 12, and enter the interior of the protective cover 12 through the circulation slot 13, where the long strips or large particles of impurities will be intercepted. At the same time, the setting of the protective pillar 14 can prevent the impurities from sticking to the surface of the protective cover 12, retain the gap for the mud to flow, and enhance the circulation effect of the mud at the protective cover 12;

[0050] Afterwards, the slurry enters the feed pipe 4 through the feed slot on the feed cover 8, wherein the setting of the feed slot can further screen the slurry entering the feed pipe 4, and large particles of debris entering the feed pipe 4 cause blockage of the feed pipe 4 and the inside of the volute 1;

[0051] After that, the mud will enter the feed pipe 4. During this process, the motor 3 will drive the turbine 2 to rotate, the turbine 2 will drive the crushing shaft 6 to rotate, and the crushing shaft 6 will drive the crushing blade 7 to rotate, so that the weeds and other materials that are easy to be entangled in the mud before entering the volute 1 will be crushed in the feed pipe 4, thereby reducing the blockage inside the volute 1 and ensuring the circulation effect of the mud pump;

[0052] During this process, when the crushing shaft 6 rotates, it will drive the cleaning frame 10 to rotate, and the rotation of the cleaning frame 10 can drive the cleaning scraper 11 to rotate, so that the impurities intercepted on the outside of the feed cover 8 can be scraped and cleaned, ensuring the unobstructed feeding of the feed trough at the position of the feed cover 8, wherein the protective cover 12 can be used for the rotation protection of the cleaning frame 10 to ensure the rotation space;

[0053] In the utility model, the cleaning plate can be elastically rotatably mounted on the cleaning frame 10 through the cooperation of the mounting shaft 15 and the torsion spring 16. In this way, when some hard debris is stuck in the feed trough, the cleaning plate can be rotated on the cleaning frame 10 to avoid rigid extrusion between the cleaning plate and the debris, which may cause the cleaning frame 10 to be stuck, thereby ensuring the smooth operation of the mud pump.

[0054] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
