Description

TECHNICAL FIELD

[0001] The utility model relates to Y filter, especially high -efficient Y shape pressure -boosting filter. BACKGROUND

[0002] Y filter is the small -size equipment of removing a small amount of solid particles in liquid, can protect the normal work of equipment, when fluid enters the filter cartridge with certain specification filter screen, its impurities are blocked, and clean filtrate is discharged by filter outlet, when needing to clean, only the detachable filter cartridge is taken out, and is reloaded after processing, therefore, it is extremely convenient to use and maintain. Y filter is also named dirt separator, filter valve, is a kind of device indispensable in pipeline system of medium conveying, its function is to filter the mechanical impurities in medium, can filter iron rust, sand particles in sewage, a small amount of solid particles in liquid etc. to protect the fittings on equipment pipeline from being abraded and blocked, can protect the normal work of equipment.

[0003] And the power station has high-temperature steam and high-temperature water after generating electricity, and the high-temperature water and the high-temperature steam are both treated specially, such as water softening, therefore, in order to save water treatment cost, the high-temperature water needs to be recycled, at this time, a heat exchanger needs to be used, and our company has developed a pressure station efficient chamber heat exchanger after long-term research, which can realize water-water heat exchange or steam-water heat exchange, in the heat exchange process, the mechanical impurities in water liquid cause abrasion or blockage to the chamber heat exchanger, and therefore, a Y filter needs to be used.

[0004] However, the existing Y filter has a large pressure difference between the water inlet end and the water outlet end after being used for a period of time, which in turn leads to a decrease in the pressure of the water outlet end, so as to cause the pressure station efficient chamber heat exchanger to have insufficient water supply pressure, such as the low-pressure Y-shaped drop filter in Chinese patent (publication number: CN221412463U), as can be seen from the drawings, the pipe diameters of the drain pipes are the same, in the water flow process, after the mechanical impurities are intercepted, the pressure difference between the two ends of the drain pipe becomes larger and larger as the impurities in the filter screen become more and more, which is also the main reason why the existing Y filter can monitor the cleaning time of the filter screen through the pressure difference, but the technical problem of the large pressure difference between the water outlet end and the water inlet end of the Y filter with use is still not solved.

[0025] like Figure 1 As shown, the high-efficiency Y-shaped booster filter includes a drain pipe 10 and a filter cartridge 20. With the drain pipe 10 draining water forward, the drain pipe 10 and filter cartridge 20 form a Y shape, and the angle between the filter cartridge 20 and the front end of the drain pipe 10 is an acute angle. The drain pipe 10 has an inlet pipe 11 at its inlet end and a drain outlet pipe 12 at its outlet end. The middle end of the drain pipe 10 is a storage pipe 13. The filter cartridge 20 is mounted on the storage pipe 13, and the inner diameter of the storage pipe 13 is larger than that of the inlet pipe 11 and the drain outlet pipe 12. The inner diameters of the inlet pipe 11 and the drain outlet pipe 12 are the same. The front wall of the filter cartridge 20, located inside the storage pipe 13, is a filter screen 21. Water flows from the inlet pipe... The water enters through inlet pipe 11 and then into the energy storage pipe 13. The flow rate of the water decreases, thereby reducing the impact force of the water and reducing the scouring force of impurities on the filter screen 21. This reduces the wear of the filter screen 21 by impurities and ensures the service life of the filter screen 21. The mechanical impurities that are intercepted settle at the bottom of the filter cylinder 20, while the water stores energy in the energy storage pipe 13. The stored water is then discharged from the drain pipe 10. Because the water stores energy in the energy storage pipe 13, the pressure difference between the inlet pipe 11 and the drain pipe 12 is small. Even if the filter cylinder is filled with mechanical impurities, the energy storage pipe 13 can still store energy, so the pressure difference between the inlet pipe 11 and the drain pipe 12 remains small, thus meeting the water supply requirements.

[0026] In this embodiment, as Figure 1As shown, an inner rifling groove 15 is formed on the inner wall of the drain pipe 10 from front to back. That is, a spiral groove is provided inside the drain pipe 10. After the water enters the drain pipe 10, it is guided by the inner rifling groove 15, so that the water flow generates a spiral swirling flow. Of course, in this embodiment, although the flow rate of the water will decrease after entering the energy storage pipe 13, the flow rate is still 2-3 meters / second, so that the water can form a swirling flow in the drain pipe 10. The swirling water can continuously flush the inside of the drain pipe 10, so that the inner wall of the drain pipe 10 is not easy to scale. Similarly, the inner rifling groove 15 is not easy to be blocked. Moreover, after the water swirls, the impurities will move towards the inner wall of the drain pipe 10 under the action of centrifugal force. When they move to the filter cylinder 20, most of the impurities can enter the filter cylinder 20 under the action of centrifugal force, further reducing the wear of impurities on the filter screen 21.

[0027] In this embodiment, as Figure 1 As shown, a sewage discharge mechanism is provided at the bottom of the filter cartridge 20. After a period of use, mechanical impurities are discharged through the sewage discharge mechanism. Furthermore, the sewage discharge mechanism includes a sewage discharge pipe 40, on which a solenoid valve 50 is installed. The solenoid valve 50 is a commercially available product, and installing a solenoid valve 50 on a pipeline is also a conventional technology. Since the pressure difference between the inlet pipe 11 and the outlet pipe 12 is small, sewage discharge can be performed by setting a time interval, such as discharging sewage every day. Of course, sewage discharge can also be performed by pressure difference. That is, pressure sensors are installed on the connecting pipes of the inlet pipe 11 and the outlet pipe 12. The operation of the solenoid valve 50 is controlled by the pressure difference between the two pressure sensors. Of course, since the pressure difference between the inlet pipe 11 and the outlet pipe 12 is small, the threshold for triggering the operation of the solenoid valve 50 cannot be set too high. In other embodiments, the sewage discharge mechanism includes a sewage pipe 40, and a cover plate is installed at the bottom of the sewage pipe 40 via a flange. Sewage is discharged by removing the cover plate. After the sewage discharge is completed, the cover plate is then installed back onto the bottom of the sewage pipe 40 via a flange.

[0028] In this embodiment, as Figure 1 As shown, a cleaning mechanism 30 is installed inside the filter cylinder 20. After a period of use, the filter cylinder 20 can be cleaned by the cleaning mechanism 30. Furthermore, the cleaning mechanism 30 includes a rotating shaft 32. The two ends of the rotating shaft 32 are rotatably located at both ends of the filter cylinder 20 through bearing seats 34. A driving device 31 for driving the rotating shaft 32 to rotate is provided at the bottom of the filter cylinder 20. Several steel brushes 33 are staggered on the rotating shaft 32 located inside the filter cylinder 20. The rotating shaft 32 is rotated by the driving device 31, so that the steel brushes 33 clean the impurities on the surface of the filter cylinder 20. The cleaned impurities will gradually settle at the bottom of the filter cylinder 20 and finally be discharged by the sewage discharge mechanism. Preferably, the sewage discharge pipe 40 is located at the lowest point of the filter cylinder 20.

[0029] In this embodiment, as Figure 1 As shown, the drive device 31 is a servo motor. By controlling the servo motor to work, the surface of the filter cartridge 20 can be cleaned periodically. In other embodiments, the drive device 31 is a handwheel, which means that the operator can clean the surface of the filter cartridge 20 by himself.

[0030] In this embodiment, as Figure 1 As shown, a power distribution box 60 is installed on the outer wall of the energy storage tube 13. The power distribution box 60 is connected to the battery valve on the sewage pipe 40 by a wire. The power distribution box 60 is also connected to the servo motor of the sewage discharge mechanism by a wire. The power distribution box 60 contains a PLC control panel, which controls the servo motor and the solenoid valve 50. In this embodiment, the PLC control panel is a commercially available product, and the PLC control panel controlling the servo motor and the solenoid valve 50 is also a conventional technology. Therefore, its specific connection and working principle will not be described in detail.

[0031] In this embodiment, as Figure 1 As shown, a gradient pipe 14 is provided between the energy storage pipe 13 and the water inlet pipe 11, and a gradient pipe 14 is also provided between the energy storage pipe 13 and the drain pipe 12. The drain pipe 10 does not have very high requirements for the smoothness of its interior, so the drain pipe 10 can be processed by casting.

[0032] In this embodiment, as Figure 1 As shown, the diameter of the drain pipe 40 is much smaller than that of the energy storage pipe 13, the inlet pipe 11, and the outlet pipe 12. Therefore, during sewage discharge, although it will affect the pressure difference between the inlet pipe 11 and the outlet pipe 12, increasing the pressure difference between them, the diameters of the energy storage pipe 13 and the drain pipe 40 are very different. Therefore, the pressure loss caused during sewage discharge cannot significantly reduce the pressure of the outlet pipe 12. Thus, in this embodiment, the high-efficiency Y-shaped booster filter can achieve cleaning and sewage discharge without stopping the machine, thereby improving the efficiency of the equipment.

[0033] In other embodiments, when the high-efficiency Y-shaped booster filter is applied to a steam boiler, a condensate drainage component is connected to the bottom of the drain pipe 40. The condensate drainage component is a prior art component, which includes a drain valve and a drain pipe. The condensate in the high-efficiency Y-shaped booster filter is discharged through the condensate drainage component, thereby reducing water hammer and noise during filter use.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
