The suction cone 1000 according to the present invention is detachably and integrally installed in the suction port of the submersible pump 20, and serves to filter foreign substances such as hair and threads from the fluid sucked in accordance with the operation of the submersible pump 20 carry out To this end, a plurality of projections are formed on the conical plate 100 of the suction cone 1000 . More specifically, as the impeller of the submersible pump 20 rotates, the fluid W is sucked into the submersible pump 20 past the suction cone 1000 and discharged to the outside, and this fluid W contains various foreign substances (F). ) is included. That is, various foreign substances F such as cloth pieces, hair, and threads are sucked together with the fluid W from fine sand, mud particles, gravel, and the like. Of these, small particles such as sand and mud are easily discharged to the outside even if they are sucked into the submersible pump 20, so they do not have a significant effect on the operation of the submersible pump 20, but foreign substances such as hair, pieces of cloth, threads, etc. (F) is sucked into the interior of the submersible pump 20, it is wound on the shaft of the impeller, etc., it can prevent the submersible pump 20 from operating properly.

However, in the conventional method of removing the foreign material F using the screen 12, etc., as discussed above, even small particles such as mud and sand are collected on the screen 12 over time, so that the fluid W Suction was not done properly, so there was a tendency to give a burden to the operation of the submersible pump (20). However, the suction cone 1000 according to the present invention does not filter all the foreign substances (F) as a whole, but is thin and long such as hair and thread that can affect the rotation of the impeller as shown in FIG. 6, and has a certain size. Since only the foreign material (F) is caught using the protrusion 110, it is possible to remove only the foreign material (F) that can affect the operation while ensuring smooth fluid (W) suction into the submersible pump (20). As a result, there is an effect that can increase the maintenance cycle of the submersible pump 20 for the removal of foreign substances (F) and the like compared to the method in which the conventional screen 12 is installed.

The suction cone 1000 according to the present invention installed and used at the front end of the suction port of the submersible pump 20 is a conical plate 100 having a plurality of protrusions 200 and a mounting for accommodating the conical plate 100 therein. It may be configured to include the unit 200 . The protrusions 110 formed on the conical plate 100 serve to remove long and thin foreign substances F, such as threads and hair, as described above, and may be formed through a pressing or casting process. In addition, the mounting unit 200 may perform a role of detachably fixing the suction cone 1000 according to the present invention to the suction port of the submersible pump 20 . For reference, these protrusions 110 may be formed through a separate process after the conical plate 100 is prepared, but may be simultaneously formed during the manufacturing process of the conical plate 100 through a pressing or casting process. Alternatively, the protrusions 110 may be formed through punching, which will be looked at again with reference to the drawings below.

The plurality of protrusions 110 formed on the conical plate 100 constituting the suction cone 1000 may have a height (BH) suitable for removing foreign substances (F) such as threads and hair (BH). There is, as an optimal example, it may be selected from 0.05 to 0.1 times the height CH of the suction cone 1000 . In the present invention, small foreign substances pass through the submersible pump 20 as it is through this configuration, but only foreign substances F that may affect the impeller rotation of the submersible pump 20 such as hair are removed to operate the submersible pump 20 ability can be guaranteed.

The protrusions 110 that are spaced apart from each other on the conical plate 100 and are independently arranged may be arranged in various shapes, FIG. 9 is one example of which the protrusions 110 are radially from the center of the conical plate 100 . It is a drawing showing the shape formed to spread. Compared to the first embodiment, the second embodiment shows a state in which more protrusions 110 are formed. Through the protrusions 110 formed in this way, the present invention provides foreign substances F such as hair and threads from the fluid W sucked in. can be effectively removed. For reference, the upper plate 210 of the mounting unit 200 may have a hole-type connection member 211 that is used when the suction cone 1000 is installed in the submersible pump 20 . There, the suction cone 1000 according to the present invention can be mounted on the submersible pump 20 by inserting a bolt here. However, the shape of the connecting member 211 is not limited thereto, and may be designed to be deformed into an appropriate shape as necessary.

11 is a view showing a top view of the suction cone according to a third embodiment of the present invention, and FIG. 12 is a view showing a top view of the suction cone according to a fourth embodiment of the present invention.

The protrusions 110 that are spaced apart from each other on the conical plate 100 and are formed independently may be arranged in a spiral. By arranging the protrusions 110 in a spiral in this way, the flow of the fluid W sucked into the submersible pump 20 is reduced. Foreign substances (F) can be removed without interfering. The spiral arrangement may be arranged along the clockwise direction as shown in FIG. 11, and may be arranged along the counterclockwise direction as shown in FIG. 12, which is a fluid W generated according to the rotation of the impeller of the submersible pump 20. It can be selected according to the direction of rotation. That is, it may be selected in a direction that does not interfere with the rotational direction of the fluid (W). Through this, the present invention ensures more smooth suction of the fluid W into the submersible pump 20, while effectively removing foreign substances F that may affect the operation, such as threads, pieces of cloth, hair, etc. have.

In more detail, a plurality of grooves 112 may be formed in the conical plate 100 through a pressing or casting process, and a screw 111 may be inserted thereto to form the protrusion 110 . In addition, threads corresponding to each other may be formed in the groove 112 and the screw 111 . For reference, the plurality of grooves 112 may be formed through a separate process after the conical plate 100 is manufactured, but may be simultaneously formed in the process of manufacturing the conical plate 100 through a pressing or casting process. .

In the case of forming the protrusion 110 using the screw 111 in this way, it is possible to remove the foreign material (F) caught by unscrewing the screw 111 from the recovered suction cone 1000, so maintenance is more convenient It has a destructive effect.

In addition, these protrusions 110 may be formed through a separate process after the conical plate 100 is manufactured, but may be formed simultaneously in the process of pressing and forming the conical plate 100 using a press or the like.

Since the formed protrusion 110 has a sharp blade, it is possible to more effectively remove long and thin foreign substances F such as threads and hair. In addition, since the protrusion 110 is simply formed through punching rather than a complicated casting process, there is an effect that the manufacturing cost can be lowered.
