Description

Technical Field

[0001] The utility model relates to an orbit assembly of a rotary grille machine, belonging to the field of sewage treatment equipment. Background Technique

[0002] Rotary grille machines are widely used in urban sewage treatment plants, waterworks, pumping stations, and the water inlets of power plants. Their function is to continuously intercept and remove floating objects in water to ensure the normal operation of the next process. They can also be used for solid-liquid separation in industries such as textile, printing and dyeing, slaughtering, leather, papermaking, and brewing. The principle is to remove floating objects in water that are larger than the rake tooth gap through the up-and-down movement of the rake teeth in the water channel. As shown in the existing rotary grille machine Figure 1 as shown, the orbit 1 is welded to the side plate 2 of the equipment shell. In order to prevent deformation, the side plate needs to be made of relatively thick stainless steel plate. The material of the orbit is 304 stainless steel. Since the orbit is the most easily worn part of the entire equipment and it is an integral structure with the shell, it cannot be repaired or partially replaced after wear. Only the entire equipment shell can be replaced or a new equipment can be directly replaced, resulting in a very high equipment operation cost. Summary of the Invention

[0003] To solve the above problems, the utility model provides an orbit assembly of a rotary grille machine, which can reduce the equipment usage cost, shorten the orbit manufacturing cycle, improve the maintenance efficiency, and increase the service life of the equipment.

[0004] To achieve the above object, the technical solution adopted by the utility model is: the orbit assembly of a rotary grille machine includes an orbit and an orbit bracket. The orbit bracket is fixedly connected to the main frame of the equipment, and the orbit is installed on the orbit bracket through bolts.

[0005] The orbit includes multiple orbit segments; it is convenient to replace, reduces the processing difficulty, and shortens the production cycle.

[0006] The orbit material is ordinary carbon steel after heat treatment, and a nickel-phosphorus anti-corrosion coating is provided on the orbit surface; it improves the wear resistance and corrosion resistance.

[0007] The orbit bracket is a rectangular frame; it improves the strength of the orbit bracket.

[0008] Advantages of the Utility Model

[0009] The utility model is an improvement on the existing track structure of a rotary grille machine. The integral structure of the original track and the equipment housing is replaced by a split structure. The track between the two driving sprockets of the equipment adopts a multi-segment splicing structure. The track support of the rectangular frame is installed on the main frame of the equipment. The original relatively thick side plate of the equipment housing is replaced by a thin steel plate, reducing the overall weight of the equipment. The track segments of the same length are continuously installed on the track support through bolts, improving the interchangeability of the track segments, reducing the difficulty of track manufacturing, shortening the production cycle. By pre-setting track spare parts, the worn track segments can be replaced in time, and there is no need to replace the equipment housing or the whole equipment, which is convenient for maintenance, reduces the use cost, and increases the service life of the whole equipment. The track uses ordinary carbon steel instead of 304 stainless steel, further reducing the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 is a schematic structural diagram of the connection between the track of the prior art and the equipment housing;

[0011] Figure 2 is a schematic structural diagram of the connection between the utility model and the equipment;

[0012] Figure 3 is a schematic diagram of the rotary grille machine installed with the utility model without side plates. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] As Figure 2-3 shown, the utility model includes a track 1 and a track support 4. The track support 4 is a rectangular frame fixed on the main frame of the rotary grille machine. The track 1 includes a plurality of track segments. Each track segment of equal length is installed on the track support 4 through bolts 3. The track segments are connected end to end to ensure the smooth movement of the rake. The material of the track 1 is ordinary carbon steel. The track 1 is heat-treated to improve its strength and then undergoes anti-corrosion treatment through a nickel-phosphorus plating process, so that the surface of the track 1 is covered with a nickel-phosphorus anti-corrosion coating, enhancing its wear resistance and anti-corrosion property.
