The terms "first", "second", and the like, as used herein do not have any specific meaning, but are used only to distinguish one element from another.

[0026] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combined with other embodiments.

[0027] Embodiments of the utility model provide a kind of filter anti-blocking structure for municipal drainage, as shown in Figures 1-6 The filter anti-blocking structure for municipal drainage includes:

[0028] The collection bin 100 is provided with a discharge port 101 at the bottom;

[0029] The second filter unit 300 includes a base plate 310 and a plurality of filter modules arranged on the base plate 310, the filter modules include a base 320 and a filter piece 330 with a conical structure, the base 320 is internally provided with a filter channel in communication with the discharge port 101, the filter piece 330 is arranged at the end of the filter channel of the base 320 away from the discharge port 101, and the water flow enters the filter channel after passing through the filter piece 330;

[0030] The first filter unit 200 includes a bottom frame 210 and a prism rod 220, the bottom frame 210 is nested on the periphery of the base 320, the prism rod 220 is in a plurality of groups and is connected to each other to form a conical structure, and the bottom surface of the conical structure is connected to the bottom frame 210,

[0031] In the embodiment, the collecting bin 100 is provided with an outer edge structure at both ends, which is buckled on the sewer culvert. Generally, two groups of blocking bars 102 can be fixed by expansion bolts to serve as support components of the outer edge structure. A commonly used flip-type grid filter net is arranged above the sewer culvert opening to serve as a preliminary filtering device.

[0032] The gap formed by the prismatic rods 220 serves as a channel for water flow. The first filtering unit 200 is mainly arranged on the outer side of the filtering module. The first filtering unit 200 preliminarily intercepts large impurities such as branches in the water flow and divides the flow through the prismatic rods 220. Large impurities are easily slid along the prismatic rods 220 and are not easily retained on the gap formed by the prismatic rods 220. The prismatic rods 220 block and reduce the large impurities from reaching the surface of the filtering module to affect the deposition of the filtering module.

[0033] The conical structure allows large impurities to slide along the inclined surface to other areas of the collecting bin 100 during the filtering process, avoiding direct coverage on the gap. The filtering piece 330 includes support rods 332 and filtering plates 331. The number of support rods 332 is four, and the support rods 332 are connected to each other to form a four-prism pyramid. The filtering plates 331 are arranged between adjacent support rods 332. The filtering plates 331 are provided with a plurality of groups of sieve holes for accommodating water flow. The filtering plates 331 serve as the main impurity filtering unit. The filtering plates 331 re-intercept and filter the impurities in the water flow that pass through the first filtering unit 200. The four-prism pyramid filtering piece 330 increases the filtering area and the possibility of impurity deposition on the filtering surface.

[0034] The second filtering unit 300 and the first filtering unit 200 are layered to trap impurities in the collecting bin 100. The collecting bin 100 can be regularly cleaned in the later stage.

[0035] As a preferred embodiment in the embodiment, the base 320 includes a primary base 321 and a secondary base 322. The primary base 321 and the secondary base 322 are provided with discharge through holes inside. The discharge through holes are in communication with a plurality of release openings provided on the base plate 310. The positions of the release openings correspond one-to-one with the discharge openings 101 at the bottom of the collecting bin 100. The water flow sequentially passing through the first filtering unit 200 and the second filtering unit 300 passes through the release openings and the discharge openings 101 in sequence through the discharge through holes and enters the sewer.

[0036] In the embodiment, the first base 321 is larger than the second base 322, and the first base 321 and the second base 322 form a stepped structure, the bottom frame 210 is nested outside the second base 322, and the bottom frame 210 is abutted on the first base 321. The bottom frame 210 is directly nested, and the second filter unit 300 and the first filter unit 200 can be separated directly after the collection bin 100 is taken out for cleaning, so that the cleaning efficiency is improved.
