Description

Technical Field

[0001] This utility model relates to the field of pipeline decontamination technology, and in particular to a horizontal straight-through decontamination device. Background Technology

[0002] The existing horizontal straight-through filter is a device used to remove and filter impurities and dirt from water in pipelines. In water treatment systems of industries such as chemical, pharmaceutical, food and beverage, and electronics, it can filter and remove dirt from production water and circulating cooling water, protect equipment, extend equipment service life, and ensure product quality.

[0003] However, in use, existing horizontal straight-through filter devices rely solely on backwashing water to clean the filter screen, which is insufficient to effectively remove stubborn impurities attached to the screen. As usage time increases, impurities gradually accumulate on the screen, leading to clogging and reduced permeability. Furthermore, the lack of a structure to prevent backflow of contaminants means that during the backwashing process, contaminants flushed towards the drain outlet may flow backward with the water, returning to the front end and resulting in incomplete cleaning. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a horizontal straight-through dirt separator. A screw drives the sealing ring to move, opening the drain port between the sleeve and the outer shell. A rotating scraper scrapes off dirt from the filter screen surface and pushes it into the sleeve, effectively removing various impurities attached to the filter screen, preventing clogging, and ensuring the filter's filtration effect and service life. Compared with the traditional method of rinsing the filter screen with water flow, the mechanical scraping action of the scraper can more thoroughly remove stubborn dirt, maintaining a high permeability of the filter screen. During filter cleaning, the support ring, in conjunction with the baffle, can block the rear end of the outer shell, forming an effective barrier to prevent dirt that has been scraped off and is ready to be discharged into the sleeve from flowing back to the front end due to water flow fluctuations, ensuring the unidirectional nature of the discharge process.

[0005] This utility model also provides a horizontal straight-through dirt separator as described above, comprising: a shell, a filter screen fixedly connected to the inner wall of the shell, a scraper rotatably connected to the front surface of the filter screen, the scraper being arc-shaped, a bracket fixedly connected to the inner wall of the shell, a motor fixedly connected to the inner surface of the bracket, the scraper being driven by the motor, a sleeve fitted onto the outer wall of the shell, the shell and the sleeve communicating through a drain port, a sealing ring slidably connected to the outer wall of the shell, the sealing ring being movably connected to the drain port, the sealing ring being located inside the sleeve, a connecting plate fixedly connected to the upper surface of the sealing ring, a lead screw rotatably connected to the inner surface of the sleeve, the lead screw being threadedly connected to the connecting plate, a flushing pipe communicating with the upper surface of the shell, a support ring fixedly connected to the inner wall of the shell, a baffle rotatably connected to the inner surface of the support ring, a conveying pipe communicating with the lower surface of the shell, and a drain pipe communicating with the lower end of the conveying pipe.

[0006] According to the present invention, a horizontal straight-through dirt separator is provided, wherein a second motor is fixedly connected to the rear surface of the sleeve, and the lead screw is driven by the second motor.

[0007] According to the present invention, a horizontal straight-through dirt separator is provided, wherein a motor is fixedly connected to the upper surface of the outer shell, and the baffle is driven by the motor.

[0008] According to the present invention, a horizontal straight-through dirt separator is provided, wherein both ends of the outer shell are fixedly connected to the outer wall of the flushing pipe with connecting flanges, and the connecting flanges are provided with connecting holes.

[0009] According to the present invention, in a horizontal straight-through dirt separator, the front and rear surfaces of the support ring are fixedly connected to limit plates, and the limit plates are movably connected to baffles.

[0010] According to the present invention, a horizontal straight-through sewage cleaner is provided, wherein a support frame is fixedly connected to the inner wall of the sewage pipe, and a motor is fixedly connected to the inner surface of the support frame.

[0011] According to the present invention, a horizontal straight-through dirt separator is provided, wherein a spiral conveying rod is fixedly connected to the output end of the motor, and the spiral conveying rod is rotatably connected inside the conveying pipe.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4This utility model embodiment provides a horizontal straight-through dirt remover, which includes: a shell 9, and a filter screen 16 fixedly connected to the inner wall of the shell 9.

[0023] Specifically: Water containing impurities enters the housing 9. As the water flows inside the housing 9, the filter screen 16 intercepts the impurities in the water flow, allowing clean water to continue flowing through the system. The impurities are trapped on the side of the filter screen 16 facing the water inlet, thus achieving the filtration function.

[0024] A scraper 15 is rotatably connected to the front surface of the filter screen 16. The scraper 15 is arc-shaped. A bracket 19 is fixedly connected to the inner wall of the outer shell 9. A motor 20 is fixedly connected to the inner surface of the bracket 19. The scraper 15 is driven by the motor 20.

[0025] Specifically: When it is necessary to clean the filter screen 16, start the motor 20. The motor 20 drives the scraper 15 to rotate on the front surface of the filter screen 16. Since the scraper 15 is arc-shaped, it can better push the impurities to the surroundings. During the rotation, the scraper 15 scrapes off the impurities attached to the surface of the filter screen 16, so that the impurities can be removed from the filter screen 16 and discharged from the dirt remover.

[0026] A sleeve 10 is fitted onto the outer wall of the outer casing 9. The outer casing 9 and the sleeve 10 are connected through a drain port 14. A sealing ring 18 is slidably connected to the outer wall of the outer casing 9. The sealing ring 18 is movably connected to the drain port 14. A slide rod 24 is fixedly connected to the inner surface of the sleeve 10. A side plate 25 is fixedly connected to the side surface of the sealing ring 18. The side plate 25 is slidably connected to the outer wall of the slide rod 24. The sealing ring 18 is located inside the sleeve 10. A connecting plate 12 is fixedly connected to the upper surface of the sealing ring 18. A lead screw 13 is rotatably connected to the inner surface of the sleeve 10. The lead screw 13 is threadedly connected to the connecting plate 12. A second motor 17 is fixedly connected to the rear surface of the sleeve 10. The lead screw 13 is driven by the second motor 17.

[0027] Specifically: Start motor 17, which drives lead screw 13 to rotate. Since lead screw 13 and connecting plate 12 are connected by a through thread, and connecting plate 12 is fixed on sealing ring 18, and the side plate 25 of sealing ring 18 is slidably connected to slide rod 24, when lead screw 13 rotates, sealing ring 18 will move along slide rod 24 under the action of lead screw 13, thereby opening drain port 14 between housing 9 and sleeve 10.

[0028] The upper surface of the outer shell 9 is connected to a flushing pipe 1. Both ends of the outer shell 9 are fixedly connected to the outer wall of the flushing pipe 1 with connecting flanges 3. The connecting flanges 3 are provided with connecting holes 5. The inner wall of the outer shell 9 is fixedly connected to a support ring 6. The inner surface of the support ring 6 is rotatably connected to a baffle 7. The upper surface of the outer shell 9 is fixedly connected to a motor 2. The baffle 7 is driven by the motor 2. The front and rear surfaces of the support ring 6 are fixedly connected to limit plates 4. The limit plates 4 and the baffle 7 are movably connected.

[0029] Specifically: During the process of cleaning the filter screen 16 and discharging sewage, in order to prevent impurities from flowing back, motor 2 can be started. Motor 2 drives the baffle 7 to rotate around the support ring 6. When the baffle 7 rotates to the appropriate position, it will be restricted by the limiting plate 4. At this time, the baffle 7 blocks the rear end of the outer shell 9, forming a barrier, so that impurities cannot flow back to the front end of the outer shell 9 under the condition of water flow fluctuation, etc., ensuring the unidirectionality of the sewage discharge process.

[0030] The lower surface of the outer casing 9 is connected to a conveying pipe 8, the lower end of the conveying pipe 8 is connected to a drain pipe 11, the inner wall of the drain pipe 11 is fixedly connected to a support frame 22, the inner surface of the support frame 22 is fixedly connected to a motor 4 23, the output end of the motor 4 23 is fixedly connected to a spiral conveying rod 21, and the spiral conveying rod 21 is rotatably connected inside the conveying pipe 8.

[0031] Specifically: the impurities scraped off by the scraper 15 are drawn into the sleeve 10 by gravity and water flow through the open drain port 14. The impurities in the sleeve 10 then fall into the conveying pipe 8. At this time, the motor 23 is started, which drives the spiral conveying rod 21 to rotate. The spiral conveying rod 21 pushes the impurities along the conveying pipe 8 to the drain pipe 11, and finally discharges them from the cleaner through the drain pipe 11.

[0032] Working principle: During use, water containing impurities enters the outer casing 9. As the water flows within the casing 9, the filter screen 16 intercepts the impurities, allowing clean water to pass through and continue flowing through the system. The impurities are trapped on the side of the filter screen 16 facing the inlet, thus achieving the filtration function. When it is necessary to clean the filter screen 16, the motor 20 is started. The motor 20 drives the scraper 15 to rotate on the front surface of the filter screen 16. Because the scraper 15 is arc-shaped, it can better push the impurities to the sides. During rotation, scraper 15 scrapes off the impurities attached to the surface of filter screen 16, allowing the impurities to detach from the filter screen 16 for subsequent discharge from the filter. The impurities scraped off by scraper 15, under the action of gravity and water flow, enter the sleeve 10 through the open drain port 14. The impurities entering the sleeve 10 then fall into the conveying pipe 8. At this time, motor 4 23 is started, and motor 4 23 drives the spiral conveying rod 21 to rotate. The spiral conveying rod 21 pushes the impurities along the conveying pipe 8 to the drain pipe 11, and finally discharges the filter from the drain pipe 11.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
