Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, and particularly relates to an inverse fishing type grille dirt remover. Background Art

[0002] The inverse fishing type grille dirt remover is one of the common sewage treatment equipment. It scoops up and discharges larger impurities in the sewage from bottom to top, playing a role in sewage pretreatment. However, when sundries are bent by the transmission structure and fall due to their own weight, there are still some sundries attached to the grille, resulting in poor pretreatment effect when entering the sewage tank. The utility model patent with the application number 202322147820.0 discloses an inverse fishing type grille dirt remover, which uses a water spraying tank and a sponge cleaning strip to clean the dirt on the grille surface. However, using clean water to clean the grille will cause further increase in sewage. On the other hand, its sponge cleaning strip is roughly at the same height at the turning of the grille and is arranged on the side of material falling, directly affecting the material falling of the sundries on the grille, and there is room for improvement.

An auxiliary collection structure is also arranged on the fixed frame, and the auxiliary collection structure is located directly below the flushing structure. The flushing structure is connected to the sewage after passing through the grille main body through a connecting pipe and a pump.

[0006] A further improvement of the inverse fishing type grille dirt remover of the utility model is that an adjusting limit roller is also arranged on the fixed frame, and the adjusting limit roller is used for tensioning and adjusting the grille main body. An auxiliary roller is also arranged between the adjusting limit roller and the transmission roller close to the material falling on the upper part of the transmission structure. Both ends of the auxiliary roller are connected to the grille main body, and a cleaning brush is arranged in the middle of the auxiliary roller. The auxiliary roller is located obliquely below the flushing structure.

[0007] A further improvement of the inverse fishing type grille dirt remover of the utility model is that the flushing structure includes a fixed pipe. A plurality of branch pipes are arranged on the fixed pipe, and the branch pipes extend into the space formed by the transmission structure and the driven grille main body. Connecting parts are arranged at both ends of the fixed pipe, and the connecting parts are connected to the fixed frame.

[0008] A further improvement of the present utility model, an inverse fishing type grille sewage cleaner, lies in that a fixed pipe is connected to a pump machine and a connecting pipe, and a filter screen is arranged inside the connecting pipe.

[0009] A further improvement of the present utility model, an inverse fishing type grille sewage cleaner, lies in that the auxiliary collection structure is a belt conveyor structure, and water leakage holes are arranged on the belt of the belt conveyor structure.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] By arranging a flushing structure inside the space formed by the transmission structure and the grille main body, facing the inclined grille, it does not affect the normal feeding of sundries on the grille main body, and also realizes the further cleaning treatment of the grille; at the same time, an auxiliary collection structure is arranged to collect the flushed sundries, preventing the sundries from entering the sewage after passing through the grille main body and forming ineffective treatment.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0016] As Figure 1 and Figure 2 shown, an inverse fishing type grille sewage cleaner includes a fixing frame 1. A transmission structure 2 is arranged on the fixing frame, and the transmission structure is used to drive the grille main body 3. The fixing frame can be an existing housing structure, and the structures and layout methods of the transmission structure and the grille main body are also one of the common structures of existing grille sewage cleaners. Further, a flushing structure 4 is also arranged on the fixing frame. The flushing structure is arranged in the upper part inside the space formed by the transmission structure and the driving grille main body. An auxiliary collection structure 8 is also arranged on the fixing frame, and the auxiliary collection structure is located directly below the flushing structure. The flushing structure is connected to the sewage after passing through the grille main body through a connecting pipe and a pump machine.

[0017] Furthermore, an adjusting limit roller 5 is also provided on the fixing frame. The adjusting limit roller is used to tension and adjust the grille main body, and the adjusting limit roller can be of an existing structure. An auxiliary roller 7 is also provided between the adjusting limit roller and the driving structure above the driving roller close to the material discharge. Both ends of the auxiliary roller are connected to the grille main body, which also has the function of limiting and stabilizing the grille main body. A cleaning brush 6 is provided in the middle of the auxiliary roller, and the auxiliary roller is located obliquely below the flushing structure. The diameter of the middle part of the auxiliary roller is smaller than that of both ends, which is convenient for installing the cleaning brush.

[0018] Furthermore, the flushing structure includes a fixed pipe 7. A plurality of branch pipes 10 are provided on the fixed pipe. The branch pipes extend into the space formed by the driving structure and the driving grille main body. Flushing heads are provided on the branch pipes. Connecting parts 11 are provided at both ends of the fixed pipe, and the connecting parts are connected to the fixing frame.

[0019] Furthermore, the fixed pipe is connected to a pump and a connecting pipe, and a filter screen is provided in the connecting pipe. The auxiliary collection structure is a belt conveyor structure, and water leakage holes are provided on the belt of the belt conveyor structure. A flow guide plate can also be provided on the fixing frame. The flow guide plate is arranged below the belt conveyor structure and is used to return the flushing sewage to the sewage pool for subsequent pre-treatment steps.

[0020] The working principle of the present utility model is as follows: Debris in the sewage is fished by the grille main body. When the grille main body turns, it falls onto the slag trough on the fixing frame by gravity. The grille main body continues to move, and the flushing structure flushes the grille, washing the remaining attached debris to the belt conveyor structure, and then the grille is scrubbed by the cleaning brush, further reducing the possibility of debris attached to the grille and improving the efficiency of sewage treatment.

[0021] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
