Description

A water supply pipeline filtering device

Technical Field

The utility model mainly relates to the technical field of pipeline filtering equipment, in particular to a water supply pipeline filtering device.

Background Art

At present, urban water supply mainly draws surface water, reservoirs, rivers, lakes and groundwater through water plant pump stations, undergoes sedimentation, disinfection, filtration and other process processes, and is finally transported to various users through distribution pump stations and pipeline networks.

The water in the water supply pipe will often produce impurities again during the circulation process. These impurities mainly come from the long-term sedimentation of impurities in a small amount of tap water, the corrosion and detachment blocks formed by the disrepair of the tap water pipes, and the deterioration of water in a small amount of pipes with poor circulation. The larger solid impurities among them may affect the normal operation of the compressor water pump or instrument. In order to remove the impurities in the pipeline, a filtering device needs to be installed on the water supply pipeline.

Traditional filtering devices for pipelines mainly connect a cylinder in series on the pipeline, and then place a filter screen in the cylinder. When tap water passes through the filter screen, solid impurity particles are blocked in the filter cylinder, while clean fluid passes through the filter cylinder and is discharged through the outlet. Although such a filter cylinder can filter impurities well, the impurities will gradually accumulate on the filter screen until it is completely blocked, interrupting the water flow of the pipeline. In order to restore the city's water supply as soon as possible, it is necessary to shut down the water supply gate as soon as possible and dismantle the filter screen for emergency repair and cleaning. Therefore, a completely blocked filtering device will not only affect the normal city water supply, but also increase the workload and difficulty of personnel scheduling due to the urgency of the emergency repair task and the short time.

Embodiment: A water supply pipeline filtering device

As shown in FIG1-2, a water supply pipeline filtering device, the specific structure of which includes:

A filter cartridge 1 is closed at both ends, and an inlet pipe 2 is fixedly installed on the top surface of the filter cartridge 1, a water outlet pipe 3 is fixedly installed on the upper part of one side of the filter cartridge 1, a filter mesh cartridge 4 is fixedly installed on the top surface of the inner wall of the filter cartridge 1, a first sealing plug 5 is slidably installed in the filter mesh cartridge 4, and a second sealing plug 6 slidably fitted therewith is sleeved on the outer periphery of the filter mesh cartridge 4, and the outer periphery of the second sealing plug 6 is tightly fitted with the inner wall of the filter cartridge 1, and a displacement component that can drive the first sealing plug 5 and the second sealing plug 6 to move up and down is provided at the bottom of the filter cartridge 1.

The displacement assembly includes a support plate 7, a spring telescopic rod 8 is fixedly installed on the bottom surface of the inner wall of the filter cartridge 1, and the movable end of the spring telescopic rod 8 is fixedly installed on the support plate 7. The bottom surfaces of the first sealing plug 5 and the second sealing plug 6 are respectively fixedly installed with a connecting rod 9, and the lower ends of the connecting rod 9 are fixedly connected to the top surface of the support plate 7. When the device is in use, the spring telescopic rod 8 can play a corresponding supporting effect on the first sealing plug 5 and the second sealing plug 6 through the support plate 7 and the connecting rod 9. When the water pressure above the first sealing plug 5 and the second sealing plug 6 is too large, the first sealing plug 5 and the second sealing plug 6 will drive the support plate 7 to move downward through the corresponding connecting rod 9, and the spring telescopic rod 8 is compressed at this time. When the water pressure above the first sealing plug 5 and the second sealing plug 6 is reduced, under the action of the spring telescopic rod 8's own elastic force, the spring telescopic rod 8 pushes the support plate 7 to move upward, so as to achieve the reset of the first sealing plug 5 and the second sealing plug 6. The structure is simple and easy to use.

A sealing ring 10 is fixedly mounted on the outer periphery of the support plate 7, and the outer periphery of the sealing ring 10 fits the inner wall of the filter cartridge 1. This structural design can increase the sealing between the support plate 7 and the filter cartridge 1, and prevent water above the support plate 7 from entering below it.

A drain pipe 11 is fixedly installed on one side of the filter cartridge 1. The drain pipe 11 is connected to the inside of the filter cartridge 1 and is located below the second sealing plug 6. A valve 12 is provided on the drain pipe 11. The drain pipe 6 can facilitate the user to drain the water leaked between the second sealing plug 6 and the support plate 7 to the outside, so as to avoid water accumulation in the space formed by the second sealing plug 6 and the support plate 7.

The top surface of the first sealing plug 5 is flush with the top surface of the second sealing plug 6. This structural design is conducive to the synchronization of the movement of the first sealing plug 5 and the second sealing plug 6 when in use, thereby improving the sealing effect of the device.

An L-shaped support rod 13 is fixedly installed on the other side of the filter cartridge 1, and an audible and visual alarm 14 is fixedly installed on the upper end of the support rod 13. A battery 15 for powering the audible and visual alarm 14 is fixedly installed on the bottom surface of the L-shaped support rod 13. A cross bar 16 is fixedly installed on one side of the inner wall of the filter cartridge 1, and a proximity switch 17 is fixedly installed on the top surface of the cross bar 16. The proximity switch 17 is electrically connected to the audible and visual alarm 14 and the battery 15. A pressure rod 18 arranged opposite to the proximity switch 17 is fixedly installed on the bottom surface of the support plate 7. When this structural design is used, when the support plate 7 moves downward, the support plate 7 drives the pressure rod 18 connected thereto to move downward synchronously. When the pressure rod 18 contacts the proximity switch 17, the audible and visual alarm 14 is powered on to work, and the audible and visual alarm 14 emits an alarm sound and emits light, thereby reminding the user that the filter screen cartridge 4 is blocked, so that the user can clean and maintain the filter screen cartridge 4 in time.

Working principle:

The working principle of this device is as follows:

When the device is in use, the water inlet pipe 2 is connected to the water supply pipeline of the city water. When the water flows into the filter cartridge 1, the impurities in the water will be intercepted by the filter screen cartridge 4, thereby achieving preliminary filtration of the water quality. When the mesh holes on the upper part of the filter screen cartridge 4 are blocked by impurities, the water flow cannot continue to pass through the filter screen cartridge 4. At this time, the water pressure in the filter cartridge 1 increases, and the first sealing plug 5 and the second sealing plug 6 move downward under the action of the water pressure, so that the unused part of the lower part of the filter screen cartridge 4 contacts the water in the filter cartridge 1. At this time, the unused part of the lower part of the filter cartridge 1 begins to play a role and continues to filter the water, thereby avoiding the impact on water supply due to the failure of maintenance personnel to arrive in time when the filter screen cartridge 4 needs to be cleaned.

In the interpretation of the present invention, it should be noted that the terminology indicating the orientation is only for the convenience of description and understanding, and is not the only limitation on the installation position of the specific technical features, and does not exclude other possible installation methods.
