Description

Technical Field

[0001] The utility model relates to the technical field of direct drinking water engineering, in particular to a raw water tank with a cleaning structure. Background Art

[0002] Direct drinking water project is a project that uses specific equipment and technology to deeply treat water sources to meet direct drinking water standards. The raw water tank is an important part of the direct drinking water project. It is usually designed at the front end of the direct drinking water treatment system to store and preliminarily treat natural water sources that have not been filtered and purified. These water sources may come from groundwater, tap water pipes or other sources;

[0003] However, the preliminary filtering device arranged inside the existing raw water tank is designed to be inside the raw water tank. As the use time increases, impurities in the raw water adhere to or even clog the filter. However, the filter is not easy to clean because it is arranged inside the raw water tank, and the cost of cleaning and maintenance is high. Therefore, we propose a raw water tank with a cleaning structure. Utility Model Content

The vortex fan is located at the inner top center of the sewage pipe. When the raw water is discharged from the sewage pipe, it will drive the vortex fan to rotate, and the L-shaped connecting rod is driven to rotate through the rotating shaft, so that the bristles on the cleaning brush can effectively remove impurities and particulate matter accumulated at the bottom of the filter screen. This automatic cleaning mechanism not only improves the filtering effect, but also reduces the frequency of manual cleaning and reduces maintenance costs.

[0006] As a preferred technical solution of the utility model, six reinforcing ribs are arranged in an equidistant circumferential array on the top surface of the filter screen plate, and the reinforcing ribs are respectively fixedly installed on the top surface of the filter screen plate, and the left and right ends of the filter screen plate are respectively fixedly connected to the outside of the connecting pipe and the inside of the box body.

Six reinforcing ribs 12 are arranged at a distance from the circumferential array, and the reinforcing ribs 12 are respectively fixedly installed on the top surface of the filter screen plate 11, and the left and right ends of the filter screen plate 11 are respectively fixedly connected to the outer side of the connecting pipe 9 and the inner side of the box body 1. The design of the reinforcing ribs 12 can enhance the connection strength between the filter screen plate 11 and the connecting pipe 9 and the box body 1. A spiral diversion and drainage hopper 6 is arranged at the bottom of the box body 1, and a sewage pipe 7 is welded at the end of the discharge port arranged at the bottom center of the spiral diversion and drainage hopper 6. An electric valve 8 is arranged in the middle of the sewage pipe 7. A drain pipe 4 is arranged on the top right side of the box body 1, and a flow meter 13 is fixedly installed in the middle of the drain pipe 4. The flow meter 13 can monitor the flow rate of raw water discharged from the discharge pipe 4. The bottom of the connecting pipe 9 is provided with a A cleaning unit 5 is provided, and the cleaning unit 5 consists of a rotating shaft 51, a vortex fan 52, an L-shaped connecting rod 53 and a cleaning brush 54. The rotating shaft 51 is arranged at the bottom center of the connecting pipe 9, and the top of the rotating shaft 51 is rotatably connected to the connecting pipe 9 through a tapered roller bearing. The bottom of the rotating shaft 51 is welded with a vortex fan 52, and the vortex fan 52 is located at the inner top center of the sewage pipe 7. The middle part of the rotating shaft 51 is respectively welded with L-shaped connecting rods 53 symmetrically on the left and right, and the top of the L-shaped connecting rods 53 is respectively fixedly installed with a cleaning brush 54. The bristles arranged in an array on the top of the cleaning brush 54 are respectively in active contact with the bottom of the filter screen plate 11. When the impurities at the bottom of the box body 1 are processed, the electric valve 2 16 can be closed and the electric valve 1 8 can be opened, and the spiral guide drainage bucket 6 plays a guiding role, so that the raw water can flow smoothly. When the raw water passes through the vortex fan 52, it drives the vortex fan to rotate. The vortex fan 52 is connected to the L-shaped connecting rod 53 through the rotating shaft 51. Therefore, the rotation of the vortex fan drives the L-shaped connecting rod 53 and the cleaning brush 54 fixed thereon to rotate together, so that the bristles on the cleaning brush 54 can effectively clean the bottom of the filter screen plate 11 and remove the accumulated impurities. It also includes a liquid level sensor 15, which is fixedly installed at the top front end of the box body 1. The sensing end of the liquid level sensor 15 is located inside the box body 1.

[0020] The working principle of the utility model is as follows: when in use, the water inlet pipe 2 is connected to the external raw water delivery pipeline, and the raw water is delivered to the inside of the box body 1 through the water inlet pipe 2. Since the water inlet pipe 2 is connected to the inside of the connecting pipe 9, the raw water is discharged from the drainage slot hole 10 to the inner bottom of the box body 1. As the water level gradually rises, the filter screen 11 can preliminarily filter the raw water rising in the box body 1, and the filtered raw water continues to rise and is finally discharged from the drainage pipe 4. The flow meter 13 on the drainage pipe 4 can monitor the flow of the discharged raw water. When the monitored flow rate gradually decreases and is lower than the preset flow setting value, the flow meter 13 sends a signal to the controller 3. After receiving the signal, the controller 3 immediately controls the electric valve 16 on the water inlet pipe 2 to close, so as to prevent the external raw water from entering the inside of the box body 1. Then, the controller 3 opens the valve 16 on the sewage pipe 7. The electric valve 18 allows the raw water inside the box 1, including the impurities accumulated at the bottom and the raw water to be filtered, to be discharged through the sewage pipe 7. During the sewage discharge process, under the diversion effect of the spiral diversion and drainage bucket 6, the raw water is driven by the vortex fan 52 when passing through it, and the vortex fan 52 drives the L-shaped connecting rod 53 to rotate through the rotating shaft 51, so that the bristles on the cleaning brush 54 clean the impurities attached to the bottom of the filter screen plate 11. At the same time, the raw water preliminarily filtered on the top of the filter screen plate 11 flows downward, thereby flushing the filter holes on the filter screen plate 11, thereby ensuring the smooth flow of the filter holes and ensuring the filtering effect. When the water level sensed by the liquid level sensor 15 is lower than the set value, a signal is sent to the controller 3, so that the controller 3 closes the electric valve 2 16 and opens the electric valve 1 8, so that the filter screen plate 11 filters the raw water again.
