Description

Technical Field

[0001] The utility model relates to the technical field of municipal facilities, and more specifically, it relates to a municipal drainage filter. Background Art

[0002] There are many garbage on municipal roads. Once it rains, this garbage will enter the urban drainage system along with the rainwater. Although the garbage with larger volume will be filtered out by rainwater gratings, some small stones and other particles will still enter the urban drainage system, and some garbage will entangle into groups in the pipeline and cause blockage of the water channel. Therefore, a filter is generally installed in the drainage system.

[0003] The existing drainage filters generally include a main pipe body and a detachable sub-pipe body. A filter screen is fixedly installed in the main pipe body. After the water flow passes through, the impurities in the water will be filtered by the filter screen, and the impurities will fall into the sub-pipe body. After using for a period of time, the sub-pipe body is disassembled and cleaned. However, such a cleaning method cannot clean the filter screen, and a large amount of impurities will remain on the surface of the filter screen after long-term work, thus greatly reducing the filtering efficiency of the drainage filter.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a municipal drainage filter to solve the above problems.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A municipal drainage filter includes a main pipe body. The main pipe body includes two main pipe openings on the same straight line and an inclined sub-pipe opening. A sub-pipe body is detachably installed in the sub-pipe opening. The sub-pipe body is slidably matched with the sub-pipe opening. An opening communicating with the main pipe body is arranged on one side of the sub-pipe body. A filter screen is fixedly connected to one end of the sub-pipe body away from the sub-pipe opening.

[0007] The utility model is further provided that: symmetrically distributed sliding grooves are arranged on the inner wall of the sub-pipe opening, and convex blocks slidably matched with the sliding grooves are fixedly connected to the sub-pipe body.

[0008] The utility model is further provided that: an annular groove communicating with the sliding groove is arranged on the inner wall of the main pipe body, and two symmetrically distributed limiting blocks are arranged in the annular groove.

[0009] The utility model is further provided that: a flange ring abutted against the sub-pipe opening is fixedly connected to one side of the sub-pipe body away from the filter screen, and the sub-pipe body and the sub-pipe opening are fixed by bolts.

[0010] The utility model is further provided that: a sealing ring is fixedly connected to one side of the sub-pipe body close to the flange ring.

[0011] The present utility model is further arranged such that: a plurality of filter grooves are arranged on the tube wall of the auxiliary tube body in a circumferentially arrayed manner.

[0012] The present utility model is further arranged such that: both the main tube body and the auxiliary tube body are made of stainless steel material.

[0013] In summary, the present utility model has the following beneficial effects:

[0014] An opening is arranged on one side of the auxiliary tube body. When the auxiliary tube body slides into the main tube body and is clamped with the main tube body, the convex block on the auxiliary tube body is in sliding fit with the sliding groove. Then, by rotating the auxiliary tube body, the convex block rotates in the annular groove and abuts against the limiting block. At this time, the opening just rotates to be in the same straight line as the main tube opening, and rainwater will flow into the auxiliary tube body through the opening. A filter screen is fixedly connected to the auxiliary tube body, and the rainwater flowing into the auxiliary tube body will flow out through the filter screen, while the filtered impurities will fall into the auxiliary tube body under the action of gravity, completing the filtration of rainwater. After using for a period of time, the auxiliary tube body is disassembled from the main tube body. Since the filter screen is fixedly connected to the auxiliary tube body, it will be disassembled together with the auxiliary tube body, which is convenient for cleaning the filter screen.

Detailed Embodiment

[0020] 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 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.

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a municipal drainage filter includes a main pipe body 1. The main pipe body 1 includes two main pipe openings 2 that are on the same straight line and a secondary pipe opening 3 that is inclined. Rainwater flows in and out through the two main pipe openings 2. A secondary pipe body 4 is detachably installed in the secondary pipe opening 3. Both the main pipe body 1 and the secondary pipe body 4 are made of stainless steel material. The stainless steel material has excellent corrosion resistance and is easy to process, so that the main pipe body 1 and the secondary pipe body 4 have a long service life. The secondary pipe body 4 is slidably fitted with the secondary pipe opening 3. Symmetrically distributed sliding grooves 7 are provided on the inner wall of the secondary pipe opening 3. A convex block 8 that is slidably fitted with the sliding groove 7 is fixedly connected to the secondary pipe body 4. When it is necessary to engage the secondary pipe body 4 with the main pipe body 1, align the convex block 8 with the sliding groove 7 and make the convex block 8 slide in the sliding groove 7. An annular groove 9 that communicates with the sliding groove 7 is provided on the inner wall of the main pipe body 1. Two symmetrically distributed limiting blocks 10 are provided in the annular groove 9. After the secondary pipe body 4 slides a certain distance, the convex block 8 abuts against the annular groove 9, and then rotate the secondary pipe body 4 so that the convex block 8 rotates in the annular groove 9 and rotates the convex block 8 to abut tightly against the limiting block 10. At this time, the annular groove 9 can play a role in limiting the convex block 8 to prevent the secondary pipe body 4 from detaching from the main pipe body 1.

[0022] As Figure 3 shown, an opening 5 that communicates with the main pipe body 1 is provided on one side of the secondary pipe body 4. When the convex block 8 rotates to abut tightly against the limiting block 10, the opening 5 just rotates to be on the same straight line as the main pipe opening 2 at this time, so that rainwater can flow into the secondary pipe body 4 through the opening 5. A filter screen 6 is fixedly connected to the end of the secondary pipe body 4 far from the secondary pipe opening 3. The rainwater flowing into the secondary pipe body 4 will flow out through the filter screen 6, and the filtered impurities will fall into the secondary pipe body 4 under the action of gravity to complete the filtration of the rainwater. A number of filter grooves 14 that are circumferentially and arrayedly distributed are provided on the pipe wall of the secondary pipe body 4. When disassembling the secondary pipe body 4, by providing the filter grooves 14, it is convenient to observe the internal situation of the secondary pipe body 4 and clean the secondary pipe body 4.

[0023] As Figure 1 and Figure 3 shown, a flange ring 11 that abuts against the secondary pipe opening 3 is fixedly connected to the side of the secondary pipe body 4 far from the filter screen 6. A perforation is provided on the flange ring 11. The secondary pipe body 4 and the secondary pipe opening 3 are fixed by bolts 12. After the secondary pipe body 4 and the main pipe body 1 are installed, the installation of the two is made more stable by the bolts 12. A sealing ring 13 is fixedly connected to the side of the secondary pipe body 4 close to the flange ring 11. By providing the sealing ring 13, it can prevent rainwater from flowing out through the secondary pipe opening 3 and ensure the overall sealing performance of the filter.

[0024] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
