Description
Technical Field
The utility model relates to the technical field of sewage treatment mechanical equipment, in particular to a chain transmission mechanism of a rotary sewage cleaner.
Background
The rotary type trash remover (also called as rotary type grating trash remover) is a special water treatment device capable of continuously and automatically intercepting and removing sundries with various shapes in fluid, can be widely applied to urban sewage treatment, can be used as a front-stage screening device in wastewater treatment processes in multiple industries, and is one of advanced solid-liquid screening devices in China. The rotary trash remover is assembled into a rotary grid chain by the rake teeth and the conveying chain, the conveying chain drives the rake teeth to perform reverse water flow direction rotary motion under the driving action of the motor reducer, the conveying chain in the process is driven by the chain-gear transmission, the driving sprocket is driven by the motor reducer to rotate, the conveying chain is connected between the driving sprocket and the driven sprocket in a transmission manner, the outer diameter of the driven sprocket is generally smaller than that of the driving sprocket and is in an underwater environment, and the chain-driven sprocket is easy to remove teeth in the operation process and is difficult to overhaul underwater based on the condition that the conveying chain is longer, so that the trash remover cannot work normally.
Disclosure of Invention
The utility model aims to provide a chain transmission mechanism of a rotary trash remover, which can solve the problems that the chain transmission mechanism of the conventional rotary trash remover is easy to remove teeth and difficult to overhaul.
The utility model provides the following technical scheme: the utility model provides a gyration trash remover chain drive mechanism, includes driving sprocket, conveying chain and driven sprocket, and driving sprocket is used for receiving motor reducer effect rotation, and driven sprocket rotates the assembly in gyration trash remover frame, and conveying chain transmission is connected between driving sprocket and driven sprocket, and driven sprocket wheel face and conveying chain sliding friction fit are in order to support conveying chain gyration motion, and driven sprocket external diameter equals the mean value of driving sprocket tooth root diameter and driving sprocket tooth top diameter.
Further, a driven sprocket shaft is fixed on the rotary trash remover frame, the driven sprocket is rotationally assembled on the driven sprocket shaft through a bearing, and a reinforcing ring fixedly connected with the rotary trash remover frame is arranged at one end of the driven sprocket shaft connected with the rotary trash remover frame.
The beneficial effects are that: according to the chain transmission mechanism of the rotary trash remover, the outer diameter of the driven sprocket is the average value of the tooth diameter of the driving sprocket and the tooth diameter of the driving sprocket, the outer diameters of the driving sprocket and the driven sprocket are approximate values, the conveying chain basically keeps the tangential direction consistent with the rotation of the driven sprocket in the conveying process, the transmission fit is tight, the driven sprocket adopts a smooth wheel surface, the rotary supporting effect of the conveying chain is achieved, the tooth disengaging problem is avoided, the conveying chain is ensured to stably rotate back and forth between the driving sprocket and the driven sprocket, and the trash remover normally works. The driven sprocket shaft is provided with the reinforcing ring, so that the connection strength of the driven sprocket shaft and the frame can be enhanced, and the driven sprocket is stably supported to rotate.

Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings.
The utility model relates to a specific embodiment 1 of a chain transmission mechanism of a rotary trash remover, which comprises the following steps:
when the utility model is used for a rotary trash remover, as shown in fig. 1, the trash remover is arranged on a rotary trash remover frame 1 and comprises a driving sprocket 2, a driven sprocket 3 and a conveying chain 4, a motor reducer is arranged on the rotary trash remover frame 1, the driving sprocket 2 is driven to rotate through the motor reducer, the driving sprocket 2 is in transmission connection with the driven sprocket 3 through the conveying chain 4, the conveying chain 4 can be driven by the driving sprocket 2 to rotate, and rake teeth 5 for intercepting sundries are arranged on the conveying chain 4.
The concrete structure of the driven sprocket 3 is shown in fig. 2, a driven sprocket shaft 6 is fixed on the rotary trash remover frame 1, and a reinforcing ring 7 fixedly connected with the rotary trash remover frame 1 is arranged on the driven sprocket shaft 6 at the outer side of the connecting end of the driven sprocket shaft 6 with the rotary trash remover frame 1 and used for improving the connecting strength of the driven sprocket shaft 6. The outside of the driven sprocket 3 is a smooth wheel surface, the inside is rotationally connected with the driven sprocket shaft 6 through a bearing 8, the outer diameter of the driven sprocket 3 is equal to the average value of the tooth root diameter of the driving sprocket 2 and the tooth top diameter of the driving sprocket 2, and when the driving sprocket 3 drives the conveying chain 4 to move, the outer wheel surface of the driven sprocket 3 is in sliding friction fit with the conveying chain 4 and is used for supporting the conveying chain 4 to rotate.
In the embodiment, the outer diameters of the driven sprocket wheel 3 and the driving sprocket wheel 2 are almost similar, so that the conveying chain 4 and the sprocket wheel 3 are basically tangential, and the two are tightly matched; the outside of the driven sprocket 3 is a smooth wheel surface, so that the problem of tooth removal of the sprocket is not worried about while the rotary supporting effect is achieved, the structural design is ingenious, the conveying chain runs stably, and the sprocket can not be removed.
