Description

Technical Field

[0001] This utility model relates to the field of filter equipment technology, specifically a T-type filter that facilitates sewage discharge. Background Technology

[0002] T-type filters, as crucial purification devices for pipeline systems in industries such as petroleum, chemical, power, and metallurgy, suffer from significant drawbacks in their traditional structure due to the lack of a dedicated sewage discharge mechanism. During maintenance, manual removal of wastewater and impurities is required, resulting in low operational efficiency and incomplete cleaning. Accumulated pipeline impurities and slag formed during inlet pipeline flushing and from detached scale deposits on the pipe walls, if not completely removed, pose three major technical risks: first, residual impurities form a complex adhesion with the pipe walls, scale deposits, and filter screen, making subsequent filter screen removal difficult; second, slag accumulation occupies the effective volume of the filter screen, causing filter screen misalignment and abnormal flange reinstallation; and third, there is a risk of impurities re-entering the pump body and downstream systems, seriously threatening equipment reliability and system stability. In particular, the problem of residual impurities in the sidewall area not only reduces filtration efficiency and shortens equipment lifespan but also significantly increases maintenance time costs and the frequency of unplanned system downtime, directly impacting enterprise operational efficiency.

[0003] Based on this, a T-type filter that facilitates sewage discharge is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, a T-type filter for easy sewage discharge includes: a filter cylinder 1, an inlet pipe 2, a cleaning mechanism, and a sewage discharge mechanism; the inlet pipe 2 is connected to the left side of the filter cylinder 1, and the right side of the filter cylinder 1 is connected to an outlet pipe 3. The ends of the filter cylinder 1, the inlet pipe 2, and the outlet pipe 3 are all provided with flanges 4. A filter element 5 is fixedly installed on the inner wall of the filter cylinder 1. A cleaning mechanism for automatically cleaning the filter element 5 is fixedly installed on the top pipe wall of the filter cylinder 1. A sewage discharge mechanism for discharging the cleaned sludge and dirt is fixedly installed on the side pipe wall of the filter cylinder 1.

[0026] The filter element 5 adopts a beveled end face design to form a flow guide bevel. The beveled end face makes the fluid enter the filter element 5 more smoothly, reducing turbulence and pressure loss at the inlet, thereby reducing system energy consumption and improving filtration efficiency; a flange 4 is set to achieve a reliable connection with the pipeline system.

[0027] In one embodiment, such as Figure 2 and Figure 3As shown, the cleaning mechanism includes a mounting bracket 6 fixedly installed on the top wall of the filter cylinder 1. A first motor 7 is fixedly installed on the top of the mounting bracket 6. A rotating rod 8 is fixedly installed at the output end of the first motor 7. A connecting rod 9 is fixedly installed at the bottom end of the rotating rod 8. A first cleaning plate 10 is fixedly installed at the end of the connecting rod 9. A second cleaning plate 11 is fixedly installed at the bottom of the connecting rod 9.

[0028] The first cleaning plate 10 has a cleaning brush on its cleaning surface for cleaning the filter element 5, and the bottom cleaning surface of the second cleaning plate 11 has a cleaning brush for cleaning the valve disc unit.

[0029] The first motor 7 drives the rotating rod 8 to rotate, and then the rotating rod 8 drives the connecting rod 9 to rotate, thereby causing the connecting rod 9 to drive the first cleaning plate 10 to clean the residual mud on the filter element 5. At the same time, the connecting rod 9 drives the second cleaning plate 11 to rotate and clean the right valve disc 16 and the left valve disc 17, thereby preventing mud accumulation and improving sewage discharge efficiency.

[0030] In one embodiment, such as Figure 4 and Figure 5 As shown, the sewage discharge mechanism includes a sliding bracket 12 fixedly mounted on the side wall of the filter cylinder 1, a cylinder 13 fixedly mounted on the inner wall of the sliding bracket 12, a guide bracket 14 slidably mounted on the inner wall of the sliding bracket 12, the output end of the cylinder 13 being fixedly connected to the end of the guide bracket 14, and a valve disc unit that can be driven by the guide bracket 14 being rotatably mounted on the inner wall of the filter cylinder 1.

[0031] The valve disc unit includes a rotating shaft 15 rotatably disposed on the inner wall of the filter cylinder 1. A right valve disc 16 is fixedly disposed on the rotating shaft 15, and a left valve disc 17 is rotatably disposed on the rotating shaft 15. The ends of the right valve disc 16 and the left valve disc 17 are both fixedly provided with drive columns 18 adapted to the guide bracket 14.

[0032] The inner wall of the sliding bracket 12 is fixedly provided with a sliding groove that is adapted to the guide bracket 14. The inner wall of the guide bracket 14 is provided with guide grooves that are adapted to the drive columns 18 on the right valve disc 16 and the left valve disc 17 respectively. The end of the drive column 18 is inserted into the guide groove.

[0033] The output end of the cylinder 13 pushes the guide bracket 14 to slide on the sliding bracket 12. At this time, the two guide grooves on the guide bracket 14 drive and guide the drive column 18 at the top of the right valve disc 16 and the left valve disc 17 respectively, so that the right valve disc 16 and the left valve disc 17 rotate simultaneously under the setting of the rotating shaft 15, thereby opening the valve body, making it easier to discharge the mud and sludge through the bottom end of the filter cylinder 1, preventing mud and sand blockage, improving working efficiency and reducing maintenance costs.

[0034] The above embodiment discloses a T-type filter that facilitates sewage discharge. In this filter, sewage is injected into the filter cylinder 1 through the inlet pipe 2 and then evenly distributed through the obliquely cut guide end face at the top of the filter element 5. The mud and sand particles are trapped on the inner wall of the filter element 5, and the filtered clean water is discharged in a directional manner through the outlet pipe 3. The first motor 7 drives the rotating rod 8 to rotate, which in turn drives the first cleaning plate 10 and the second cleaning plate 11 to perform bidirectional cleaning through the connecting rod 9. The first cleaning plate 10 spirally scrapes away the plated mud along the inner wall of the filter element 5, while the second cleaning plate 11 simultaneously cleans the sealing surfaces of the right valve disc 16 and the left valve disc 17, achieving zero dead angle self-cleaning of the filtration system. The output end of the cylinder 13 pushes the guide bracket 14 to slide on the sliding bracket 12. At this time, the two guide grooves on the guide bracket 14 drive and guide the drive column 18 at the top of the right valve disc 16 and the left valve disc 17, respectively, so that the right valve disc 16 and the left valve disc 17 rotate simultaneously under the setting of the rotating shaft 15, thereby opening the valve body and facilitating the discharge of mud through the bottom end of the filter cylinder 1, preventing mud and sand blockage, improving working efficiency and reducing maintenance costs.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
