[0020] In order to make the utility model's purpose, technical scheme and advantage more clearly clear, the following refers to the drawing and gives the preferred embodiment, and the utility model is further detailedly explained. However, it is explained that many details listed in the specification are only for making the reader have a thorough understanding to one or more aspects of the utility model, and even if there is no these specific details, the aspect of the utility model can be realized.

[0021] Please refer to Figures 1 to 2 The utility model provides a kind of suction device for sewage treatment, technical scheme is as follows:

[0022] Including suction pipe 1, the suction pipe 1 is U-shaped pipe, and vertically arranged, filter plate 2 is equipped in the suction pipe 1, filter box 3 is equipped on the outer circumference of the suction pipe 1, discharge port 4 is opened on the inner wall of the suction pipe 1, and discharge port 4 is communicated with filter box 3, filter ring 5 is equipped in filter box 3, connecting pipe 6 is equipped on filter box 3, and another end of connecting pipe 6 is connected with suction pipe 1, filter ring 5 is located on the side of filter box 3 close to connecting pipe 6, filter plate 2 is inclinedly arranged towards flow direction.

[0023] In the process that suction device carries out suction treatment to sewage, impurity, suspended matter or particle, such as silt, exists in sewage, when transporting and moving via suction pipe 1, these impurities can deposit in pipeline, especially in bending or pipeline connection, easy to form blockage, and then cause the efficiency reduction of sewage suction;Sewage contacts filter plate 2 after passing through U-shaped bend, and larger impurities are intercepted by filter plate 2, since filter plate 2 is inclinedly arranged, then impurities can be accumulated in the lower end of filter plate 2, and impurities accumulated in the lower end of filter plate 2 enter filter box 3 through discharge port 4 cooperating with filter plate 2, and impurities are filtered again via filter ring 5 in filter box 3, then impurities stay in filter box 3, and wait for manual cleaning filter box regularly, or replace filter box, guarantee the stability of suction pipe 1 suction sewage, reduce the stoppage of the whole equipment due to blockage.

[0024] ​The suction pipe 1 is symmetrically provided with two grooves 7, each of which is provided with a spring 8, and the two springs 8 are connected with the filter plate 2, the filter box 3 is located behind the filter plate 2 along the flow direction, and the discharge port 4 is arranged on the inner wall of the suction pipe 1.

[0025] When there are more impurities on the filter plate 2, the filtering efficiency of the filter plate 2 is reduced, and then the filter plate 2 is driven to extrude the springs 8 on both sides by the power given when the sewage moves, so that the filter plate 2 is extruded above the discharge port 4, and since the filter plate 2 is arranged obliquely, a guiding effect is achieved, and under the action of gravity and the flow pressure of the sewage, the impurities enter the filter box from the discharge port 4, and then the filtering efficiency of the filter plate 2 is improved, and the spring 8 drives the filter plate 2 to reset; and one of the grooves 7 is provided with a proximity switch, which is triggered when the spring 8 is extruded, and after the proximity switch is continuously triggered for a period of time, a warning signal is sent to the outside, indicating that the impurities in the filter box have been filled up, thereby affecting the filtering effect of the filter plate 2, and the suction of the sewage in the suction pipe 1 is objectively observed.

[0026] The suction pipe 1 is externally connected with a side pipe 9, and the side pipe 9 is provided with a filter screen 10 at the connection position with the suction pipe 1; when the suction pipe 1 is blocked, backflow is avoided, and then the subsequent sewage can flow through the blocked area through the side pipe 9, and the filter screen 10 intercepts the impurities, thereby improving the fault tolerance of the suction pipe 1.

[0027] The side pipe 9 is arranged perpendicular to the ground, and the side pipe 9 is located directly above the suction pipe 1; when the sewage is being sucked, the U-shaped suction pipe 1 is generally arranged on a plane, and the amount of suction generally does not completely fill the entire suction pipe 1, so that when the blockage does not occur, the sewage is reduced to enter the side pipe 9 directly above the suction pipe 1, thereby avoiding the impurities adhering to the filter screen 10, and reducing the probability of blockage of the filter screen 10.

[0028] The filter plate 2 is provided with a baffle 11; the baffle 11 plays a role of shielding the inlet of the side pipe 9, and when the filter plate 2 is driven to move by the sewage, the baffle 11 moves to open the inlet of the side pipe 9, so that the sewage passes through the blocked area through the side pipe 9, thereby ensuring the flowability of the suction pipe 1.

[0029] The discharge port 4 is chamfered; the chamfering plays a guiding role and improves the efficiency of the impurities entering the filter box.

[0030] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
