[0017] In the following, the application will be further described in combination with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0018] As Figs. 1-3 shown in the figure, a high-efficiency rotary filter machine includes a frame 1 and a filter cylinder 2 arranged on the frame 1, the frame 1 is provided with a motor 3, the motor 3 is used to drive the filter cylinder 2 to rotate, the frame 1 is also provided with a mud scraping mechanism 4, the mud scraping mechanism 4 includes a base 41 and a scraper 42, the side of the base 41 away from the filter cylinder 2 is provided with a rotating groove 411, a pair of rotating seats 412 are arranged in the rotating groove 411, a guide plate 43 is arranged between the pair of rotating seats 412, the guide plate 43 can rotate between the pair of rotating seats 412, one end of the guide plate 43 is located below the scraper 42, the other end of the guide plate 43 penetrates out of the rotating groove 411 and extends to the outside of the frame 1.

[0019] In the process of driving the filter cylinder 2 to rotate by the motor 3, the scraper 42 remains stationary, so that the scraper 42 can scrape the sludge on the surface of the filter cylinder 2. After the sludge falls off the filter cylinder 2, it will move downward along the surface of the scraper 42 and fall onto the guide plate 43, and the guide plate 43 can rotate so that the guide plate 43 can always be in an inclined state and the inclination angle can be adjusted. When the guide plate 43 remains at an angle for a period of time, the sludge will accumulate in a conical shape, at this time, the guide plate 43 is rotated to another angle and remains, so that the falling point of the sludge changes, thereby making the sludge accumulation more uniform, effectively reducing the sludge accumulation height, and leaving enough time for the worker to clean the sludge, thereby preventing the sludge from accumulating too high and rolling into the inside of the frame 1, effectively improving the overall processing efficiency.

[0020] The scraper 42 is arranged obliquely at the top of the rotating groove 411, the length of the scraper 42 is greater than the length of the rotating groove 411, and the length of the rotating groove 411 is greater than the length of the filter cylinder 2, so that after the filter cylinder 2 rotates for one revolution, the scraper 42 can reliably scrape the sludge on the surface of the filter cylinder 2, and the scraped sludge can all fall into the rotating groove 411 and be received by the guide plate 43, improving the transfer effect of the sludge and preventing the sludge from falling everywhere and polluting the operating environment.

[0021] A plurality of support plates 44 are arranged on the base 41, the plurality of support plates 44 are arranged at intervals along the length direction of the base 41, and the support plates 44 are used to support the scraper 42. The support plates 44 can be triangular and are detachably connected between the base 41 through bolts, and the support plates 44 are arranged on the side of the scraper 42 close to the filter cylinder 2, so that after the support plates 44 and the scraper 42 are installed, the support plates 44 can form reliable support for the scraper 42, thereby ensuring that the position of the scraper 42 is fixed.

[0022] The bottom of the base 41 is provided with a threaded hole 413, a adjusting screw 45 is rotatably arranged in the threaded hole 413, one end of the adjusting screw 45 is located below the base 41, the other end of the adjusting screw 45 extends into the rotating groove 411 and contacts the bottom of the guide plate 43, the bottom of the rotating groove 411 is provided with a spring 46, one end of the spring 46 is connected with the base 41, the other end of the spring 46 is connected with the bottom of the guide plate 43, the adjusting screw 45 and the spring 46 are respectively located on both sides of the rotating seat 412. When the adjusting screw 45 moves away from the guide plate 43, the scraper will be in a horizontal state under the action of the spring 46. When the adjusting screw 45 is screwed into the guide groove and contacts the guide plate 43, and the adjusting screw 45 is continuously rotated, a pushing action is formed on the guide plate 43, thereby reliably adjusting the angle of the guide plate 43, and the current angle can be automatically locked after adjustment.

[0023] The side of the adjusting screw 45 in contact with the guide plate 43 is hemispherical, so that the friction between the adjusting screw 45 and the guide plate 43 can be significantly reduced during the process of rotating and rising of the adjusting screw 45 and pushing the guide plate 43, thereby ensuring that the guide plate 43 can be reliably pushed to rotate while prolonging the service life of the guide plate 43.

[0024] The top of the guide plate 43 is provided with a groove 430, the groove 430 extends along the length direction of the guide plate 43, that is, when the sludge moves downward along the surface of the scraper 42, it will fall into the groove 430 and slide in the groove 430 until it is separated from the guide plate 43, so that the sludge can be gathered to the middle of the groove 430, thereby improving the control accuracy of the sludge falling point and effectively preventing the sludge from rolling towards both sides of the guide plate 43.

[0025] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application are within the scope of protection of the present application.
