Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it is to be understood that the described embodiments are merely illustrative of some, but not all, embodiments of the invention.

As shown in fig. 1 to 3, the present embodiment provides a sludge scraper for sewage treatment, which comprises a mounting plate 1, a driving motor 2 disposed in the middle of the upper portion of the mounting plate 1 and electrically connected to an external power source, and a side sludge scraping arm 3 and a lower sludge scraping arm 4 disposed below the mounting plate 1. The position of the driving motor 2 and the lower side of the mounting plate 1 are sequentially provided with a transmission shaft 21, a guide rod 22 and a fixed seat 23 from top to bottom along the central axis, and the shaft of the driving motor 2 penetrates through the mounting plate 1 to be connected with the transmission shaft 21 below. The side mud scraping arms 3 are telescopic and are multiple, and each side mud scraping arm 3 is respectively and symmetrically arranged on the periphery of the fixed seat 23 in a way of rotating up and down; and one end far away from the fixed seat 23 is provided with a side mud scraper 36 capable of moving up and down. The lower mud scraping arm 4 is arranged at the bottom of the fixed seat 23, and a lower mud scraping plate 41 is arranged at one end, far away from the fixed seat 23, of the lower mud scraping arm 4.

Preferably, a groove 24 for allowing the side mud scraping arm 3 to rotate up and down is formed at the position of the side mud scraping arm 3 on the peripheral side of the fixed seat 23, and the side mud scraping arm 3 pivots in the groove through the rotating shaft 31. The side wiper arm 3 includes an outer arm 32 and an inner arm 35. An expansion groove 33 which is opened towards one end far away from the groove 24 and is used for the inner arm 35 to enter and exit is arranged in the outer arm 32, the diameter of the expansion groove 33 is matched with that of the inner arm 35, and a spring 34 is arranged between the bottom end of the expansion groove 33 and the inner arm 35; when the outer arm 32 and the inner arm 35 are in the maximum extension state, the spring 34 is in a natural state. Preferably, when the side wiper arm 3 is in a horizontal state, the upper inner wall of the groove 24 is in close contact with the side wiper arm 3.

Preferably, the lower wiper arm 4 also comprises an outer arm 32, a spring 34 and an inner arm 35 in accordance with the structure of the side wiper arm 3. Scrape mud arm 4 movably down and locate fixing base 23 bottom, and scrape the periphery of mud arm 4's focus in fixing base 23 bottom center down. The lower wiper plate 41 is movably pivotable in the direction from the outside to the center of gravity of the lower wiper arm 4. Preferably, the lower mud scraper 41 extends upward at a position away from the center of the bottom of the fixed base 23 and on a side of the lower mud scraper 41 adjacent to the sewage tank. Preferably, the number of the lower mud scraping arms 4 is two, and the two mud scraping arms are parallel to each other and are arranged at the bottom of the fixed seat 23 in a centrosymmetric manner.

Based on foretell structure, the utility model discloses a mud scraper for sewage treatment, mounting panel 1 are fixed in effluent water sump mouth department. When using, start driving motor 2, driving motor 2 drives transmission shaft 21 and guide arm 22 rotatory to it is rotatory to drive fixing base 23, and the side mud arm 3 of scraping on fixing base 23 is located and mud arm 4 is scraped under with and is also driven rotatoryly. When driving motor 2 rotational speed is less, the centrifugal force of going up the 3 departments of mud scraper is less, the elasticity that is not enough to overcome spring 34 makes the side mud scraper arm 3 upwards remove, clear up to the more place of below sludge deposit, when needs carry out special mud scraping to the position that the lateral wall is more, can increase driving motor 2's rotational speed, side mud scraper 3 can slowly rebound, at this moment, the upside inner wall of recess 24 has restricted side mud scraper 3 and can not exceed the horizontality, thereby stop side mud scraper 3 and go beyond the sewage pool mouth under the spring action of spring 34 under the horizontality, guarantee safe in utilization. The rotating speed of the driving motor 2 is periodically increased and reduced, and the lower mud scraper 4 periodically and spirally moves while rotating under the action of the periodic increase and reduction of centrifugal force to scrape mud at each corner of the pool bottom without dead angles.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
