Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a cleaning structure for grid rake teeth. Background Art

[0002] The rake grid dirt remover is one of the common sewage treatment equipment. Driven by a motor reducer, the rake tooth chain rotates in the reverse water flow direction to lift and discharge large particle impurities in the sewage. Among them, when the rake tooth chain is transported to the top, the sundries fall into the collection structure by their own gravity. However, there are still some impurities attached to the rake teeth, resulting in a low cleaning effect. To solve the above problems, the utility model patent with the application number 202121165933.8 discloses a grid machine with a rake cleaning function, which increases the cleaning effect of the rake teeth by setting a cleaning roller. However, only relying on a group of cleaning rollers to clean the rake teeth has limited cleaning effect on the impurities stuck in the grid gaps, and there is room for improvement. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a cleaning structure for grid rake teeth with good cleaning effect aiming at the deficiencies in the above background art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figure 1As shown in the figure, a cleaning structure of a grid tooth rake includes a fixing frame 1. A transmission structure 2 is provided on the fixing frame, and a grid tooth rake main body 3 is arranged on the transmission structure. The above structure is a conventional structure of an existing grid tooth rake machine. A cleaning structure for cleaning the grid tooth rake is also provided on the fixing frame. Specifically, the cleaning structure includes an impact structure 4. The impact structure is in the shape of a cam. The impact structure can be connected to a forward and reverse motor through a rotating rod 12 to achieve reciprocating movement, perform simple impacts on the grid tooth rake, and thus facilitate knocking down some stuck impurities, improving the cleaning effect. The impact structure is arranged inside the space formed by the transmission structure and the grid tooth rake main body, and is close to the discharging position of the grid tooth rake main body. The cleaning structure also includes a brush roller 5. The brush roller is arranged outside the space formed by the transmission structure and the grid tooth rake main body, and is located on one side of the impact structure away from the discharging position of the grid tooth rake main body.

[0020] Furthermore, an adjusting roller 6 is also provided on the fixing frame. The adjusting roller is located inside the space formed by the transmission structure and the grid tooth rake main body, and is located below the brush roller. The adjusting roller is used to adjust the tension degree. At the same time, it also makes the inclination angle of the grid main body above the adjusting roller larger, facilitating cleaning and discharging.

[0021] Furthermore, as Figure 2 and Figure 3 shown in the figure, a row of anti-blocking plates 8 is provided on the impact structure. Protrusions 9 are provided on the anti-blocking plates. The protrusions are used to reciprocate in and out of the grid gaps of the grid tooth rake main body. Impacts are made on the possible blockages in the grid gaps to further improve the cleaning ability.

[0022] As Figure 4 shown in the figure, another embodiment of the connection between the anti-blocking plate and the impact structure is that a through groove 0 is opened along the length direction at the protruding end of the impact structure. The anti-blocking plate is arranged on a fixing rod 10, and the fixing rod and the anti-blocking plate are arranged in the through groove. Specifically, the fixing rod is a threaded rod, and threaded holes are provided on the anti-blocking plate. Both ends of the fixing rod are connected to the impact structure through connecting pieces 11. The position of the anti-blocking plate can be adjusted to adapt to different grid gaps.

[0023] The working principle of the present utility model is as follows: Impurities are fed at the upper rightmost end at the top and fall by gravity. Some impurities adhere to the grid tooth rake main body. The impact structure works to slightly collide with the grid, improving the discharging of impurities. At this time, the anti-blocking plate can move in the grid gaps to impact the blocked impurities, further improving the cleaning effect. Then, the brush on the brush roller works for final cleaning to ensure the cleaning effect of the overall grid tooth rake.

[0024] 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 the present utility model 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 embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
