Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tank scraper equipment, in particular to a central transmission scraper structure. Background Art

[0002] A sludge scraper is a type of sludge removal equipment used in sewage treatment sedimentation tanks at sewage treatment plants. It scrapes away sludge that has settled on the bottom of the tank and collects it in a central sludge collection pit. An existing Chinese utility model patent application numbered 202321227067.X discloses a centrally driven sludge scraper for a sedimentation tank. This scraper utilizes a sludge discharge assembly to remove any sludge that may be present on the scraper blades. However, the sludge discharge assembly is arranged vertically in this structure, while the bottoms of most sedimentation tanks are generally inclined. Consequently, an inclined arrangement of the scraper blades is preferred, making a vertically arranged sludge discharge assembly unsuitable for most sedimentation tanks, leaving room for improvement. Utility Model Content

[0003] The purpose of the utility model is to address the deficiencies in the above-mentioned background technology and to provide a central transmission scraper structure that adapts to the inclined sedimentation tank bottom and ensures the mud cleaning effect of the scraper.

[0004] To achieve the above purpose, the utility model adopts a central transmission scraper structure, which adopts the following technical solutions:

[0005] A central transmission scraper structure includes a rotating rod, a scraper arm is provided on the rotating rod, a scraper plate is provided on the scraper arm, the scraper arm is arranged at an angle, a bracket is also provided on the rotating rod, the bracket is located above the scraper arm, a vertically arranged connecting rod is provided between the end of the bracket and the end of the scraper arm, a movable rod is slidably connected between the connecting rod and the rotating rod, and the sliding direction is the length direction of the lower end of the scraper plate, a second scraper arm is slidably connected to the movable rod, the second scraper arm is provided with a second scraper plate, and the second scraper plate is in staggered contact with the scraper plate.

[0006] The further improvement of the central transmission scraper structure of the utility model is that a fixed block is provided on the connecting rod and the rotating rod. The fixed block is in the shape of a long strip and is arranged along the sliding direction of the movable rod. The movable rod is arranged at an angle, and the inclination direction is the same as the inclination direction of the scraper arm.

[0007] A further improvement of the central transmission scraper structure of the utility model is that the sliding direction of the second scraper arm relative to the movable rod is the same as the length direction of the movable rod.

[0008] The further improvement of the central transmission scraper structure of the utility model is that the upper front end of the scraper plate is connected to the scraper arm, and the upper rear end of the second scraper plate is connected to the second scraper arm.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The utility model arranges two groups of scrapers to cooperate with each other, which can not only scrape the mud, but also facilitate the two to clean the silt from each other, thereby ensuring the mud cleaning effect of the scrapers. At the same time, it is also suitable for most of the existing sedimentation tanks with inclined bottom surfaces. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural diagram of the utility model;

[0012] In the figure: 1 rotating rod, 2 scraper arm, 3 scraper blade, 4 bracket, 5 connecting rod, 6 fixed block, 7 movable rod, 8 second scraper arm, 9 second scraper blade. DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] like Figure 1 The structure of a central drive scraper is shown, comprising a rotating rod 1, a scraper arm 2 mounted on the rotating rod, and a scraper blade 3 mounted on the scraper arm. The scraper arm is arranged at an angle. The rotating rod is also provided with a bracket 4 positioned above the scraper arm. A vertical connecting rod 5 is provided between the end of the bracket and the end of the scraper arm. This structure is a common structure of existing central drive scrapers. Furthermore, a movable rod 7 is slidably connected between the connecting rod and the rotating rod, sliding in the direction of the length of the lower end of the scraper blade. A second scraper arm 8 is slidably connected to the movable rod, and a second scraper blade 9 is mounted on the second scraper arm. The second scraper blade is in offset contact with the scraper blade.

[0015] Furthermore, a fixed block 6 is provided on the connecting rod and the rotating rod. The fixed block is in the shape of an elongated strip and is arranged along the sliding direction of the movable rod. The movable rod is arranged tilted, and the tilting direction is the same as the tilting direction of the scraper arm.

[0016] The sliding direction of the second scraper arm relative to the movable rod is the same as the length direction of the movable rod. The above sliding connection mode can be a conventional telescopic cylinder connection form.

[0017] Furthermore, the upper front end of the scraper plate is connected to the scraper arm, and the upper rear end of the second scraper plate is connected to the second scraper arm, so as to prevent the scrapers from being restricted by the positions of the scraper arm and the second scraper arm when scraping each other.

[0018] The working principle of the utility model is as follows: after the sedimentation tank is scraped, the machine is stopped, and the movable rod moves relative to the connecting rod and the rotating rod along the length direction of the scraper, that is, the scraper and the second scraper are in contact and slide on one side to achieve mutual scraping action between the two. After completion, the second scraper arm moves, and then the relative movement between the two scrapers is repeated to achieve scraping of the other side of the two scrapers.

[0019] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
