[0002] Rotary bar screens are specialized water treatment equipment that can continuously and automatically intercept and remove debris of various shapes from fluids, and can be widely used in wastewater treatment.
[0003] Existing rotary bar screens are installed with the lower end submerged in water and the upper end fixed to the ground. However, there is a problem that the water depth is difficult to adjust. Specifically, since the length of the rotary rake teeth of the rotary bar screen is fixed, the depth of the lower end of the rotary bar screen submerged in water can only be reduced by raising the installation end, or by replacing it with a longer rotary rake tooth.
[0004] Therefore, it is necessary to improve existing technologies. Summary of the Invention

[0049] Example 1
[0050] Reference Figure 1-4 As shown in this embodiment, a rotary bar screen includes:
[0051] The support frame 100 includes a support housing 110 and sliding base feet 120 disposed on both sides of the support housing 110.
[0052] The rotary rake tooth section 200 includes a rake tooth conveying assembly 210 installed in the support housing 110 and a drive member 220 installed on the upper end of the support housing 110. The drive member 220 is connected to the rake tooth conveying assembly 210 and drives the rake tooth conveying assembly 210.
[0053] In this embodiment, the support housing 110 is formed by the enclosure and connection of a top cover 112, a bottom plate, a left side plate, a right side plate 111, and a rear side plate; the support housing 110 has a front opening, and an outlet 102 is provided between the top cover 112 and the upper end of the rear side plate; a gap is left between the top cover 112 and the upper end of the rake tooth conveying assembly 210 to form an inlet 101.
[0054] In this embodiment, the slide base 120 includes a base 121 mounted on the left or right side plate 111 of the support housing 110, and a guide rod 122 fixedly disposed in the base 121. A slider 123 is movably mounted on the guide rod 122, and a support foot block 124 is connected to the side of the slider 123. A locking bolt is threaded on the slider 123, and the slider 123 is locked on the guide rod 122 by the locking bolt, thereby realizing the positioning of the support foot block 124.
[0055] In this embodiment, the rake tooth conveying assembly 210 includes a rake tooth belt 213, a first rotating shaft 211 installed at the lower end of the support housing 110, and a second rotating shaft 212 installed at the upper end of the support housing 110. The rake tooth belt 213 is installed between the first rotating shaft 211 and the second rotating shaft 212. The driving component 220 includes a drive motor 221 installed on the top cover 112 and a chain drive component 222 connected to the output end of the drive motor 221. Specifically, the chain drive component 222 includes a driving wheel, a driven wheel, and a chain. The driving wheel is installed at the output end of the drive motor 221. One end of the second rotating shaft 212 extends out of the support housing 110, and the driven wheel is installed on the extended end of the second rotating shaft 212. The chain is installed between the driving wheel and the driven wheel.
[0056] Example 2
[0057] This embodiment does not have a locking bolt, but all other configurations are the same as in Embodiment 1.
[0058] Based on the required immersion depth of the rotary bar screen, adjust the position of the slider 123 on the guide rod 122, and then adjust the position of the support foot block 124 of the slide base 120: when the support foot block 124 moves with the slider 123 to the lower end of the guide rod 122, the lower end of the rotary bar screen is immersed in the water at a shallow depth; when the support foot block 124 moves with the slider 123 to the upper end of the guide rod 122, the lower end of the rotary bar screen is immersed in the water at a deeper depth. During installation and adjustment, according to the required immersion depth, slide the slider 123 on the guide rod 122 to the set position, tighten the locking bolts to fix the position, and then install and fix the support foot block 124 with bolts; finally, tilt the lower end of the rotary bar screen into the water, and place the base plate of the support foot block 124 on the ground.
[0059] When the rotary bar screen is running, the lower part of the rake tooth belt 213 is submerged in water. Driven by the drive motor 221, the rake tooth belt 213 rotates against the direction of water flow. When sewage flows through the rake tooth belt 213, solid debris in the water is intercepted and hooked by the rake teeth. As the rake tooth belt 213 rotates, the solid debris is separated from the liquid. The solid debris is conveyed to the upper end by the rake tooth chain and discharged to the ground through the discharge port 102. The liquid flows through the gaps between the rake teeth, thereby achieving solid-liquid separation.
[0060] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
