Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtration, in particular to a sewage filter for industrial pipelines. Background Art

[0002] Since sewage often contains many impurities, the debris in the sewage needs to be separated and discharged when the sewage is discharged. The common treatment method is to add a filter net in the pipeline. After the filter net is fixed in the pipeline, the debris in the sewage is blocked. When the existing filter finely filters the sewage, the small particles of impurities in the sewage are separated on the surface of the filter net and block the filter mesh, resulting in the need for frequent replacement of the filter net, which greatly reduces the sewage filtration efficiency. For this reason, we propose a sewage filter for industrial pipelines. Utility Model Content

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a sewage filter for industrial pipelines.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sewage filter for industrial pipelines, comprising a filter box, both sides of the filter box are fixedly installed with connecting pipes, and the ends of the two connecting pipes that are far away from each other are installed with flange ring structures for connecting external pipes. A separation chamber is provided inside the filter box, and a card-mounting groove is provided at the top opening part of the separation chamber. A filter frame is inserted and installed inside the card-mounting groove. The filter frame is a long horizontal plate structure, and both ends of the filter frame are fixedly installed with lifting holes of a semicircular ring structure. The filter frame is pulled to move by pulling the lifting holes. Installation columns are fixedly installed on the bottom surfaces of both ends of the inner side of the card-mounting groove, and the two ends of the filter frame are provided with alignment jacks that are adapted to the outer diameter of the installation columns. After the filter frame is card-mounted into the inner side of the card-mounting groove, the installation columns are inserted into the upper part of the corresponding alignment jacks and locked by nuts. The overall structure of the filter frame is a T-shaped structure, and a card-mounting cavity is provided inside the lower end of the filter frame. The outer wall surfaces on both sides of the bottom of the filter frame are hollow and paved with filter nets, and an isolation and disassembly plate is inserted and installed inside the card-mounting cavity.

[0005] Furthermore, corresponding limit blocks are provided on the inner wall surfaces at both ends of the card cavity, and limit slots of the same size as the limit blocks are provided on the outer wall surfaces at both ends of the isolation and disassembly plate. After the isolation and disassembly plate is inserted into the interior of the card cavity, the limit blocks are inserted into the corresponding limit slots.

[0006] Furthermore, a through hole for sewage to flow through is opened at the inner center of the isolation and disassembly plate, and a mounting shaft is movably mounted at the inner center of the isolation and disassembly plate through a mounting frame.

[0007] Furthermore, two buffer blades with the same rotation direction are installed on the outer surface of the installation shaft. The buffer blades are inclined structures. After the two buffer blades are installed, they fit with the surface of the inner circular hole part of the isolation and disassembly plate.

[0008] Furthermore, a cleaning brush for cleaning is fixedly installed on the left wall surface of the buffer blade, and after the isolation disassembly plate is inserted into the interior of the card installation cavity, the cleaning brush contacts the screen inside the partition filter.

[0009] Beneficial Effects

[0010] The utility model provides a sewage filter for industrial pipelines, which has the following beneficial effects:

[0011] 1. The sewage filter for industrial pipelines is provided with a cleaning brush for automatic cleaning. After the cleaning brush is installed on the external surfaces of both sides of the buffer blade, the buffer blade is mounted in the internal through hole of the isolation disassembly plate. After the installation is completed, the buffer blade can be rotated inside the isolation disassembly plate, and then the isolation disassembly plate is inserted into the interior of the card cavity from bottom to top, so that the limit card block is inserted into the limit card slot corresponding to the surface of the isolation disassembly plate, and the isolation disassembly plate is placed to move horizontally. After the isolation disassembly plate is inserted, the cleaning brush is fitted with the screen surface inside the separation filter. During daily sewage filtration, external water flows through the separation filter and impacts the surface of the buffer blade. Because the two buffer blades are inclined structures, the water flow impacting the surface of the buffer blade will drive the buffer blade to rotate inside the isolation disassembly plate. The cleaning brush scrapes the surface of the separation filter during the rotation of the buffer blade, takes away impurities attached to the surface of the screen inside the separation filter, reduces the occurrence of blockage of the screen mesh inside the separation filter, and greatly improves the self-cleaning ability of the device.

[0012] 2. The industrial pipe sewage filter is provided with a filter frame that is convenient for disassembly and assembly. Two mounting posts are fixedly mounted on the bottom surfaces of both sides of the inner side of the card slot. After the isolation disassembly plate is mounted inside the card cavity and the installation is completed, the filter frame is inserted into the separation cavity. The bottom surface of the isolation disassembly plate is abutted against the inner bottom surface of the separation cavity. After the filter frame is fully inserted between the two mounting posts, the position of the isolation disassembly plate will be locked. After the two mounting posts extend to the top of the corresponding alignment jacks, the nut is put on the top of the mounting post and rotated and locked to complete the installation. The position of the filter rack is fixed. After the filter rack is installed inside the separation chamber, the external sewage enters the separation chamber through the connecting pipe, and will pass through the preset screen inside the separation filter to separate impurities. When the external water flow becomes larger, the water flow impacts the surface of the buffer blade and drives the cleaning brush to rotate inside the isolation disassembly plate. The cleaning brush cleans the holes of the screen inside the separation filter to reduce blockage. When the screen inside the separation filter needs to be replaced, the nuts on the top of the two mounting columns can be released to pull out the filter rack through the two pulling holes, which greatly improves the speed of disassembly and replacement of the device.

A separation chamber 5 is opened inside the filter box 1, and a card-mounting groove 3 is opened at the top opening of the separation chamber 5. A filter frame 4 is inserted and installed inside the card-mounting groove 3. The filter frame 4 is a long horizontal plate structure. Both ends of the filter frame 4 are fixedly installed with lifting holes 8 of a semicircular ring structure. The filter frame 4 is pulled to move through the lifting holes 8, and the inside of the card-mounting groove 3 Mounting posts 6 are fixedly installed on the bottom surfaces of both ends, and alignment holes 7 that match the outer diameter of the mounting posts 6 are opened inside the two ends of the filter frame 4. After the filter frame 4 is snapped into the interior of the snap-in groove 3, the mounting posts 6 are inserted above the corresponding alignment holes 7 and locked by nuts. The filter frame 4 is a T-shaped structure as a whole and a snap-in cavity 10 is opened inside the lower end of the filter frame 4. The outer walls on both sides of the bottom of the filter frame 4 are hollow and covered with filter nets, and an isolation and disassembly plate 12 is inserted and installed inside the snap-in cavity 10.

[0020] The inner wall surfaces at both ends of the card cavity 10 are provided with corresponding limit blocks 11, and the outer wall surfaces at both ends of the isolation and disassembly plate 12 are provided with limit slots 13 of the same size as the limit blocks 11. After the isolation and disassembly plate 12 is inserted into the inner part of the card cavity 10, the limit blocks 11 are inserted into the corresponding limit slots 13.

[0021] A through hole for sewage to flow through is opened at the inner center of the isolation and disassembly plate 12. A mounting shaft 14 is movably installed at the inner center of the isolation and disassembly plate 12 through a mounting frame. Two buffer blades 15 with the same rotation direction are installed on the outer surface of the mounting shaft 14. The buffer blades 15 are an inclined structure. After the two buffer blades 15 are installed, they fit into the surface of the inner circular hole part of the isolation and disassembly plate 12.

[0022] A cleaning brush 16 for cleaning is fixedly installed on the left wall of the buffer blade 15. After the isolation and disassembly plate 12 is inserted into the card cavity 10, the cleaning brush 16 contacts the screen inside the partition filter 9. When the sewage inside the filter box 1 flows through the inside of the filter frame 4, the sewage hits the surface of the buffer blade 15, which will drive the buffer blade 15 to rotate inside the isolation and disassembly plate 12, and the cleaning brush 16 will rotate with the buffer blade 15 to rub the screen inside the partition filter 9.

[0023] The working principle of this utility model:

[0024] By providing a cleaning brush 16 with automatic cleaning, after the cleaning brush 16 is installed on the outer surfaces of both sides of the buffer blade 15, the buffer blade 15 is mounted in the internal through hole of the isolation disassembly plate 12. After the installation is completed, the buffer blade 15 can rotate inside the isolation disassembly plate 12, and then the isolation disassembly plate 12 is inserted from bottom to top into the interior of the card cavity 10, so that the limiting card block 11 is inserted into the limiting card groove 13 corresponding to the surface of the isolation disassembly plate 12, and the isolation disassembly plate 12 is placed to move horizontally. After the isolation disassembly plate 12 is inserted and installed, the cleaning brush 16 and The screen surfaces inside the partition filter 9 are fitted together. During daily sewage filtration, the external water flows through the partition filter 9 and impacts the surface of the buffer blades 15. Because the two buffer blades 15 are inclined structures, the water flow hitting the surface of the buffer blades 15 will drive the buffer blades 15 to rotate inside the isolation disassembly plate 12. The cleaning brush 16 scrapes the surface of the partition filter 9 during the rotation of the buffer blades 15, taking away impurities attached to the screen surface inside the partition filter 9, reducing the occurrence of blockage of the screen mesh inside the partition filter 9, and greatly improving the self-cleaning ability of the device.

[0025] By providing a filter frame 4 that is convenient for disassembly and assembly, the two mounting posts 6 are fixedly mounted on the bottom surfaces of both sides of the inner side of the card slot 3, and the isolation disassembly plate 12 is mounted inside the card cavity 10. After the installation is completed, the filter frame 4 is inserted into the separation cavity 5, and the bottom surface of the isolation disassembly plate 12 is abutted against the inner bottom surface of the separation cavity 5. After the filter frame 4 is fully inserted between the two mounting posts 6, the position of the isolation disassembly plate 12 will be locked. After the two mounting posts 6 extend to the top of the corresponding alignment sockets 7, the nut is put on the top of the mounting post 6 and rotated and locked to complete the position of the filter frame 4. After the filter rack 4 is fixed and installed inside the separation chamber 5, the external sewage enters the separation chamber 5 through the connecting pipe 2, and will pass through the preset screen inside the separation filter 9 to separate impurities. When the external water flow becomes larger, the water flow impacts the surface of the buffer blade 15 and drives the cleaning brush 16 to rotate inside the isolation disassembly plate 12. The cleaning brush 16 cleans the holes of the screen inside the separation filter 9 to reduce blockage. When the screen inside the separation filter 9 needs to be replaced, the nuts on the top of the two mounting columns 6 can be released to pull out the filter rack 4 through the two pulling holes 8, which greatly improves the speed of disassembly and replacement of the device.
