[0036] Embodiment 1: the preferred embodiment of the preliminary filtering device for municipal engineering sewage treatment provided by the utility model as shown in the figure: a preliminary filtering device for municipal engineering sewage treatment, comprising: Figures 1 to 5 Treatment box 1, the left side surface of treatment box 1 is provided with discharge pipe 2 in communication, the valve is installed in the discharge pipe 2, the support leg 3 is fixedly installed on the bottom surface of the four corners of treatment box 1, the cross bar 4 is fixedly installed between the support legs 3 corresponding to the front and rear positions, the support leg 3 can be installed to play the role of stable support to treatment box 1, which is convenient for sewage filtering treatment work;

[0037] Filtering assembly 5, which is connected with the top surface of treatment box 1;

[0038] Separation assembly 6, which is provided in three groups, and the three groups of separation assembly 6 are installed with filtering assembly 5.

[0039] Separation assembly 6, which is provided in three groups, and the three groups of separation assembly 6 are installed with filtering assembly 5.

[0040] The filtering assembly 5 comprises:

[0041] A filtering plate 51 is arranged at an upper position of the treatment box 1 in an inclined manner, and the filtering plate 51 can perform a preliminary filtering action on the sewage.

[0042] A connecting spring 52 is fixedly installed at a top end of the filtering plate 51 and at a bottom end of the right end of the treatment box 1, and the connecting spring 52 can vibrate the filtering plate 51 under the impact of the sewage and the filtering plate 51, thereby accelerating the filtering speed and avoiding the blocking of the filtering plate 51.

[0043] A connecting part 54 is arranged between the filtering plate 51 and the treatment box 1.

[0044] The connecting part 54 comprises:

[0045] A first connecting rod 541 is fixedly installed at a bottom surface of the filtering plate 51, and the first connecting rod 541 is movably connected with an active rod 542 through a pin.

[0046] A second connecting rod 542 is movably connected with the active rod 542 through a pin, and an end portion of the second connecting rod 542 is fixedly installed at the treatment box 1. The connecting part is arranged to support the end portion of the filtering plate 51 and not to affect the vibration effect of the filtering plate.

[0047] In this embodiment, the front surface of the filtering plate 51 is fixedly installed with two baffle plates 53, and the two baffle plates 53 are symmetrically arranged at front and rear positions with the center of the front surface of the filtering plate 51 as the symmetry axis. The two baffle plates 53 can prevent the sewage from overflowing from the two sides of the filtering plate 51 and affecting the sewage treatment.

[0048] In the above embodiment, the separating assembly 6 comprises:

[0049] An elastic member 61 is in a triangular shape and is fixedly installed at a top surface of the filtering plate 51 in an inclined manner.

[0050] The top surface of the elastic member 61 is provided with filtering holes, so that the sewage can be filtered when the impurities pass through.

[0051] An L-shaped plate 62 is fixedly installed at an end surface of the elastic member 61 in an inclined manner, and the top surface of the L-shaped plate 62 is provided with a separating groove 63, and the inner wall of the separating groove 63 is provided with filtering holes. The separating groove can be used to treat the accumulation of impurities, which is convenient for centralized treatment in the later period, and the filtering holes can be used to filter the moisture penetrated by the accumulated impurities.

[0052] In this embodiment, the elastic member 61 is made of an elastic sheet material.

[0053] Working principle: when sewage flows through the filter plate 51, it will produce a certain impact force. Thanks to the ingenious design of the connecting spring 52, when the filter plate 51 is impacted by sewage, the connecting spring 52 will produce elastic deformation, thereby driving the filter plate 51 to vibrate. This vibration can effectively speed up the filtration speed of the sewage, so that the impurities in the sewage can pass through the filter plate 51 more quickly; on the other hand, it can promote the impurities to quickly enter the separation tank 63, greatly facilitating the subsequent centralized treatment of the impurities.

[0054] At the same time, due to the action of the elasticity 61, the L-shaped plate 62 will also vibrate. In the vibration process, the impurities accumulated in the separation tank 63 are constantly stirred, and the water mixed therein will penetrate from the filter hole of the separation tank 63, realizing further separation of solid and liquid, and finally completing the filtration discharge. The whole process is simple and efficient to operate.

[0055] The above merely describes the specific embodiments of the present application, and is not intended to limit the scope of the present application. Any person skilled in the art, without departing from the concept and principle of the present application, makes equivalent changes and modifications, which should belong to the scope of protection of the present application. Moreover, it should be noted that the components of the present application are not limited to the above overall application, and the technical features described in the specification of the present application can be selected for single use or combined use according to actual needs, therefore, the present application naturally covers other combinations and specific applications related to the present application.
