Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and fig. 2, a ring type mud scraper comprises a sedimentation tank 1 and a driving rod 2 arranged in the middle of the sedimentation tank, wherein the driving rod 2 is driven by a driving device arranged at the upper end of the driving rod, the driving device is arranged on a working bridge, the working bridge adopts a truss structure, a steel grating is laid on the bridge floor, the driving rod has high strength and light weight, the bottom surface of an inner cavity of the sedimentation tank 1 is a conical bottom surface 11, a mud collecting groove 12 is formed in the middle of the conical bottom surface 11, the mud in the mud collecting groove 12 is discharged through a mud discharging pipe, a rake frame 21 is arranged at the lower end of the driving rod 2, the rake frame 21 is generally designed in a logarithmic manner, two or four symmetrical parts are arranged, a plurality of supports 13 are connected below the sedimentation tank 1, and the sedimentation tank 1 is lifted up by the plurality of supports 13.

After the traditional ring type mud scraper is used for a long time, the mud scraper 7 is worn and abraded, the mud scraper and the conical bottom surface 11 are not attached to each other, certain deviation exists, the cleaning efficiency and the quality of the mud scraper are reduced, meanwhile, the width of a rake frame 21 installed on the traditional mud scraper is fixed, the size of the installed mud scraper 7 is also fixed, but the mud flows towards the mud collecting groove 12 in the middle of the traditional mud scraper along the conical bottom surface 11, so that more mud is treated by the mud scraper 7 near the mud collecting groove 12, the borne pressure is higher, the sludge treated by the mud scraper 7 far away from the mud collecting groove 12 is correspondingly less, the mud scraper 7 with the same size is adopted at present, the device quality is larger, the energy consumption is increased, and based on consideration of the problems, technicians in the field perform long-term groping and testing to creatively develop the ring type mud scraper, and the ring type mud scraper is mainly characterized in that: this rake frame 21 of mud scraper is provided with multiunit self-adaptation and scrapes the mud subassembly, and the self-adaptation is scraped the mud subassembly and is hugged closely in order to realize higher quality of decontaminating with tapered bottom surface 11 all the time, and the extension direction equal proportion of multiunit self-adaptation along rake frame 21 of scraping the mud subassembly reduces or enlargies, can be according to what of the mud of scraping the board 7 and handling, accurate matching size reduces the energy consumption.

As shown in fig. 2, a stabilizer bar 22 is connected between the driving rod 2 and the rake frame 21, the stabilizer bar 22 plays a role of stabilizing the rake frame 21, the width of the rake frame 21 decreases in an equal proportion from one end connected with the driving rod 2 to the other end, and the angle of the rake frame is inclined upwards, because the rake frame 21 is matched with the gradient of the conical bottom surface 11, compared with the traditional ring type mud scraper, the invention arranges a plurality of groups of self-adaptive mud scraping assemblies on the rake frame 21, so that the mud scraping plate 7 is always in tight contact with the conical bottom surface 11 of the sedimentation tank 1, the mud scraping efficiency is improved, and the pressure for cleaning the conical bottom surface 11 at the later stage can be relieved.

As shown in fig. 3-6, when the adaptive mud scraping assembly of the present invention is assembled, the mounting base 3 is firstly mounted on the bottom surface of the rake frame 21, and then the hollow tube 4 is screwed into the accommodating cavity 32, the first screw thread 31 is screwed with the second screw thread 42, during the screwing process, the output end of the nitrogen spring 33 is abutted against the sliding column 5 inside the hollow tube 4, and when the upper end of the hollow tube 4 is abutted against the nitrogen spring 33, the rotation of the hollow tube 4 is stopped, where it should be mentioned that the sliding groove 41 does not completely penetrate through the hollow tube 4, both ends thereof are sealed, the limiting block 51 is slidably sleeved with the sliding groove 41, so as to ensure that the sliding column 5 cannot be separated from the hollow tube 4 along the sliding groove 41, and the adaptive mud scraping assembly is also mounted.

As shown in fig. 4, because the diameter of the output end of the nitrogen spring 33 is smaller than the diameter of the inner cavity of the hollow tube 4, the output end of the nitrogen spring 33 can directly extend into the inner cavity of the hollow tube 4 and abut against one end of the sliding column 5, so as to urge the sliding column 5 to move downwards straightly, as shown in fig. 7 and 8, the bottom end of the mud scraping plate 7 and the bottom end of the mounting frame 6 are located on the same plane, and the two are tightly abutted against the conical bottom surface 11 under the driving of the sliding column 5, thereby achieving the purpose of improving the cleaning quality and efficiency.

Besides, in the present invention, the mud scrapers 7 are not completely fixed, the mud scrapers 7 can rotate along the rotating shaft 62 in the movable groove 61 by a certain angle, and the rotation angle and frequency between the plurality of mud scrapers 7 are synchronously performed under the action of the connecting rod 71, in this embodiment, both ends of the connecting rod 71 are rotatably connected to the adjacent mud scrapers 7, which can effectively prevent the mud from being jammed between the plurality of mud scrapers 7, thereby reducing the cleaning efficiency of the mud scraper, even if the plurality of mud scrapers 7 are movable, in the continuous rotation process of the rake 21, compared with the conventional mud scraper, the clogging probability is lower.

The distance between the mounting frames 6 is not too large, so that the sludge between the adjacent mud scraping plates 7 is prevented from being retained on the conical bottom surface 11.

In the description herein, references to the description of "one embodiment," "an example," "a specific example," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
