[0002] In the fields of industrial production and water treatment, generators, as key equipment, are widely used in various chemical reactions, steam generation, gas generation and other process processes. The efficient operation of these generators depends on a clean and stable water supply. In actual use, water sources often contain various impurities, such as suspended matter, particulate matter, organic matter, microorganisms, etc. If these impurities enter the generator directly without effective treatment, they will have a serious impact on the normal operation of the equipment. Filtering is required at the water inlet position of the generator to ensure the normal operation of the generator.

[0003] However, after a period of use, the filter head currently used for the water inlet of the generator will usually cause a lot of impurities to accumulate on the surface of the filter element, resulting in the filter element needing to be frequently cleaned and replaced. The cleaning and replacement methods generally require the housing of the filter head to be disassembled and the filter element to be taken out for cleaning and replacement. This operation is relatively cumbersome, time-consuming and labor-intensive, and brings more troubles to the user. At the same time, for this reason, the applicant proposes a water inlet filter device for the generator to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The utility model provides a technical solution: a water inlet filtering device for a generator, comprising a filtering mechanism 2 and a cleaning mechanism 3 assembled in the filtering mechanism 2, a filter element 4 assembled on the inner side of the cleaning mechanism 3 and a protective mechanism 1 assembled on the filtering mechanism 2, the filtering mechanism 2 comprises a mounting seat 201, the bottom of the mounting seat 201 is connected to a docking joint 204 through a connecting pipe 203, the cleaning mechanism 3 comprises a plurality of limiting frames 301 rotatably mounted on the inner side of the mounting seat 201 and distributed in an annular array, one side of the limiting frame 301 is fixedly mounted with a plurality of guide vanes 306 arranged at equal distances, the inner side of the limiting frame 301 is provided with a groove 302, the interior of the groove 302 is fixedly mounted with a cleaning brush 303 that contacts the filter element 4, the bottom of the limiting frame 301 is fixedly mounted with a chassis 305 for placing the filter element 4, the protective mechanism 1 comprises a mounting sleeve 103 threadedly mounted on the outer side of the mounting seat 201, and the top of the mounting sleeve 103 is fixedly connected with a protective cover 101 that wraps around the outer side of the cleaning mechanism 3.

[0024] Based on the above-mentioned structural setting, the water inlet filtration device for the generator is composed of a protective mechanism 1, a filtering mechanism 2, a cleaning mechanism 3 and a filter element 4. The filtering mechanism 2 is connected to the water suction end of the generator, and the filter element 4 can be used to filter impurities in the water source. The protective mechanism 1 can conveniently wrap the cleaning mechanism 3, which can prevent the cleaning mechanism 3 from being hit by external objects during use. The rotation of the cleaning mechanism 3 can clean the impurities accumulated on the surface of the filter element 4, so that the filter element 4 can maintain a good filtering effect.

[0025] Specifically, in the working process, by inserting the filter element 4 between the limiting frames 301, the bottom of the filter element 4 can be supported by the chassis 305, and the limiting frames 301 can be used to limit the four sides of the filter element 4, so that the filter element 4 will not shake. By sleeve-fitting the mounting sleeve 103 on the mounting seat 201, the mounting sleeve 103 can be threadedly connected to the mounting seat 201 by rotating it, so that the protective cover 101 can cover the outside of the cleaning mechanism 3, which can conveniently form a protective effect for the cleaning mechanism 3. The docking joint 204 can be conveniently inserted into the water suction pipe of the generator, which is convenient for connecting the connecting pipe 203 with the water suction end of the generator. The filter element 4 is connected to the generator, which can easily absorb water. Impurities in the water source can be filtered through the filter element 4, so that the filtered water can be introduced into the generator through the connecting pipe 203. The guide vane 306 is set as an angle, and the flow effect of the water flow can be used to generate a thrust on the guide vane 306, which can drive the limit frame 301 to rotate. The rotation effect of the limit frame 301 can be used to use the cleaning brush 303 to clean the impurities accumulated on the surface of the filter element 4, so that the filter element 4 can maintain a good filtering effect, avoid clogging, maintain long-term operation, reduce the trouble of frequent disassembly, cleaning and replacement, and improve the use effect.

[0026] Furthermore, a rotating ring 304 is fixedly mounted on the outer side of the limiting frame 301, and a sliding groove 206 is formed on the inner wall of the mounting base 201 for the rotating ring 304 to rotate. The sliding groove 206 limits the rotating ring 304, allowing the rotating ring 304 to rotate along the sliding groove 206, so that the limiting frame 301 can rotate stably.

[0027] Furthermore, a turntable 202 is fixedly mounted on the outside of the mounting base 201, and a plurality of anti-slip strips 105 are evenly distributed in a circular array on the outside of the mounting sleeve 103. The turntable 202 facilitates the rotation of the mounting base 201, facilitating the screw-type installation between the mounting base 201 and the mounting sleeve 103. The anti-slip strips 105 prevent the mounting sleeve 103 from slipping when being held.

[0028] Furthermore, the outer side of the mounting base 201 is provided with a spiral pattern 205, and the inner wall of the mounting sleeve 103 is provided with a thread groove 104 that cooperates with the spiral pattern 205. The thread groove 104 cooperates with the spiral pattern 205 to facilitate threaded installation and fixation of the mounting sleeve 103 and the mounting base 201, thereby preventing the protective cover 101 from falling off.

[0029] Furthermore, a plurality of limiting posts 106 arranged in a circular array are fixedly mounted on the top of the inner wall of the protective cover 101, and a plurality of limiting holes 401 corresponding to the limiting posts 106 are formed on the top of the filter element 4. When the protective cover 101 is installed, the limiting posts 106 can be inserted into the limiting holes 401, thereby conveniently limiting and fixing the filter element 4 so that the filter element 4 does not rotate. This allows the filter element 4 to be cleaned while the cleaning mechanism 3 rotates.

[0030] Furthermore, a plurality of through holes 102 are formed on the surface of the protective cover 101, and the through holes 102 are distributed in a circular array along the vertical direction of the protective cover 101. The through holes 102 allow water to enter the protective cover 101, so that the filter element 4 can filter impurities in the water.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
