Description

Technical Field

[0002] Sewage flow meter is a key equipment in environmental protection projects. It can monitor sewage discharge, provide data support for process adjustment and optimization, ensure that enterprises discharge according to regulations, and prevent excessive discharge from causing environmental pollution.

[0003] The existing announced patent CN218600625U discloses a sewage flow monitoring device. By setting a filter residue net, when in use, the connecting plate can be placed into the interior of the flow chamber and pushed toward the impeller side. When the connecting plate is in contact with the wall of the flow chamber, the position of the connecting plate can be limited by a limiting mechanism. During this period, water flows through the water hole to the impeller side. The filter residue net set in the water hole can filter out impurities in the water, which is convenient to use.

[0004] During the use of the above-mentioned device, the filter residue net is used to filter impurities in sewage. When impurities accumulate on the outside of the filter residue net and affect the flow of liquid, personnel need to remove the filter residue net from the monitoring table for cleaning. Since the impurity content in the sewage is an uncertain value, the cleaning of the filter residue net is irregular, which makes it difficult to control the cleaning time of the filter residue net. Moreover, when cleaning the filter residue net, in order to prevent sewage from being discharged from the installation position of the filter residue net, the sewage discharge gate needs to be closed to clean the filter residue net, which seriously affects the normal discharge of sewage.

The upper end of the spring 503 is movably abutted against a positioning ring 504.

[0024] See also Figure 3 The positioning ring 504 is fixedly connected to the U-shaped tube 2, and a plurality of limiting rods 505 equidistantly distributed in a circle are fixedly installed on the lower end of the positioning ring 504, and the connection between the fixed frame 501 and the limiting rods 505 is a sliding contact, and the limiting rods 505 can limit the rotation of the fixed frame 501, and the lower end of the fixed frame 501 is movably abutted against a retaining ring 8, and the retaining ring 8 is fixedly connected to the U-shaped tube 2.

[0025] See also Figure 4 The cleaning structure 6 includes an impeller 601 that can rotate inside the U-shaped tube 2. A connecting shaft 602 is fixedly embedded at the center of the upper end of the impeller 601. A positioning frame 603 is installed on the outer side of the connecting shaft 602. The connecting shaft 602 is rotatably connected to the positioning frame 603 through a bearing. The bearing can reduce the friction between the connecting shaft 602 and the positioning frame 603. The positioning frame 603 is fixedly connected to the U-shaped tube 2.

[0026] See also Figure 4 A spline rod 604 is movably embedded in the upper end of the connecting shaft 602, and the upper end of the spline rod 604 is rotatably connected to the fixed frame 501. Two symmetrically distributed scrapers 605 are fixedly installed on the outer side of the spline rod 604. The scrapers 605 can rotate outside the filter screen 502, and the scrapers 605 are movably fitted with the filter screen 502.

[0027] The working principle that can prevent the filter from being blocked: when the monitor 1 is performing online monitoring of the flow at the sewage outlet, the liquid flow in the U-tube 2 drives the impeller 601 to rotate, and the rotation of the impeller 601 drives the scraper 605 to rotate through the connecting shaft 602 and the spline rod 604. The scraper 605 rotates in contact with the filter 502, which can effectively prevent impurities from accumulating on the outside of the filter 502, and prevent impurities from clogging the filter 502 and affecting the liquid flow in the U-tube 2. There is no need to remove the filter 502 to clean the filter 502.

[0028] Example 2: Please refer to Figure 4 This embodiment further explains Example 1. The driving assembly 7 includes a connecting rod 701 fixedly installed on the outside of the connecting shaft 602, and the connecting rod 701 is close to the upper end of the connecting shaft 602.

[0030] In this embodiment: during the rotation of the impeller 601 and the connecting shaft 602, the connecting shaft 602 drives the top rod 702 to rotate through the connecting rod 701. During the rotation of the top rod 702, the top of its hemispherical portion will resist the top bead 703, and the fixed frame 501 will be driven to move upward through the top bead 703. After the top rod 702 rotates and disengages from the top bead 703, the fixed frame 501 will move downward driven by the spring 503. This reciprocating motion can cause the fixed frame 501 and the filter screen 502 to produce continuous vibration, which is beneficial to further improve the anti-blocking effect of the filter screen 502.
