Correctly measuring fluid flow plays an important role in ensuring product quality, improving production efficiency, and promoting scientific and technological development.

[0003] Flow meters are usually used in various fields, so the media that need to be measured are also different. Some media usually contain impurities. Therefore, during long-term use, the flow meter is easily blocked, resulting in inaccurate measurement of the liquid medium or the inability of the liquid medium to flow. In view of this, a flow meter with an anti-blocking mechanism is proposed to solve the above problem. Utility Model Content

Some media usually contain impurities. Therefore, during long-term use, the flow meter is easily blocked, resulting in inaccurate measurement of the liquid medium or the inability of the liquid medium to flow.

[0005] To achieve the above object, the utility model provides the following technical solutions: a flow meter with an anti-blocking mechanism, comprising a flow meter body, both ends of the flow meter body are respectively fixedly welded with mounting flanges, the interior of the flow meter body is fixedly connected with a supporting ring, and the interior of the supporting ring is rotatably connected with a permeable filter element;

[0006] A liquid outflow cavity is provided at one end of the permeable filter element. The permeable filter element is barrel-shaped by the liquid outflow cavity, so that the liquid can only penetrate into the inside of the permeable filter element and then flow out through the liquid outflow cavity.

[0007] An impeller ring is fixedly sleeved on one end of the permeable filter element away from the supporting circular ring, and a guide plate is fixedly connected to the impeller ring;

[0008] A mounting plate is fixedly connected to the inner wall of the flow meter body, and a hard brush is fixedly connected to one end of the mounting plate close to the permeable filter element.

[0014] Preferably, the impurity collecting tube is rotatably connected to a rotating shaft inside, and a spiral blocking plate is fixedly welded to the rotating shaft.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The flow meter with anti-blocking mechanism, when the liquid passes through the permeable filter element, the impurities in the liquid are completely filtered out, thereby effectively preventing the impurities from corroding and damaging the measuring elements of the flow meter body. At the same time, when the liquid flows, the driving force generated by the liquid flow drives the impeller ring and the permeable filter element to rotate together through the guide plate. Therefore, during the rotation of the permeable filter element, the bristle brush continuously brushes the surface of the permeable filter element, thereby effectively avoiding its blockage, thereby ensuring the normal flow of the liquid, thereby ensuring the normal monitoring of the liquid flow by the flow meter body, thereby ensuring the normal use of the device, and reducing the cost expenditure caused by maintenance and replacement.

[0017] 2. The flow meter with an anti-blocking mechanism has a sealed bearing, so that the permeable filter element can rotate more smoothly, reducing the force required to push it, so that the liquid can normally drive the permeable filter element to rotate during the flow process.

[0018] 3. The flow meter with anti-blocking mechanism has a baffle plate, so when the liquid flows through the sewage pipe, the force of the liquid flow causes the baffle plate and the rotating shaft to rotate. Therefore, the baffle plate can continuously transport impurities downward through its own spiral shape, thereby avoiding the backflow phenomenon caused by impurities left behind, thereby ensuring that impurities will not cause secondary pollution to the permeable filter element.

[0029] See also Figure 1-4 The utility model provides a technical solution: a flow meter with an anti-blocking mechanism, comprising a flow meter body 1, and mounting flanges 2 are respectively fixedly welded at both ends of the flow meter body 1;

[0030] A supporting ring 3 is fixedly connected to the inside of the flow meter body 1, and a permeable filter element 4 is rotatably connected to the inside of the supporting ring 3;

[0031] A liquid outflow cavity is provided at one end of the permeable filter element 4. The liquid outflow cavity is provided so that the permeable filter element 4 is barrel-shaped, so that the liquid can only penetrate into the inside of the permeable filter element 4 and then flow out through the liquid outflow cavity.

[0032] An impeller ring 7 is fixedly sleeved on one end of the permeable filter element 4 away from the supporting ring 3, and a guide plate 8 is fixedly connected to the impeller ring 7;

[0033] The guide plates 8 are arranged in an inclined manner, and the guide plates 8 are arranged in an annular array on the impeller ring 7;

[0034] A mounting plate 5 is fixedly connected to the inner wall of the flow meter body 1, and a bristle brush 6 is fixedly connected to one end of the mounting plate 5 close to the permeable filter element 4;

[0035] When the liquid passes through the permeable filter element 4, the impurities in the liquid are completely filtered out, which can effectively prevent the impurities from corroding and damaging the measuring elements of the flow meter body 1. At the same time, when the liquid flows, the driving force generated by the liquid flow drives the impeller ring 7 and the permeable filter element 4 to rotate together through the guide plate 8. Therefore, during the rotation of the permeable filter element 4, the bristle brush 6 continuously brushes the surface of the permeable filter element 4, thereby effectively avoiding its clogging, thereby ensuring the normal flow of the liquid, thereby ensuring the normal monitoring of the liquid flow by the flow meter body 1, thereby ensuring the normal use of the device and reducing the cost expenditure caused by maintenance and replacement.

[0036] Furthermore, a sealing bearing 14 is fixedly connected to the inner wall of the supporting ring 3, and the permeable filter element 4 is fixedly connected to the inner wall of the rotatable inner ring of the sealing bearing 14;

[0037] By providing the sealing bearing 14, the permeable filter element 4 can rotate more smoothly, reducing the force required to push it, so that the liquid can normally drive the permeable filter element 4 to rotate during the flow process.

[0038] Furthermore, a rubber sealing pad 15 is fixedly connected to the arc surface of the supporting ring 3;

[0039] By setting the rubber sealing pad 15, the support ring 3 and the flow meter body 1 are sealed to avoid leakage of liquid in the gap, thereby ensuring the filtering effect of the liquid and avoiding the inflow of impurities carried by the liquid, thereby reducing the possibility of blockage.

[0040] Furthermore, an impurity collecting pipe 9 is fixedly connected to the flow meter body 1, and a sewage pipe 10 is fixedly connected to the surface of the impurity collecting pipe 9;

[0041] The sewage pipe 10 is provided with a sewage valve 11, and the sewage valve 11 is initially in a closed state;

[0042] As the impurities cleaned by the bristle brush 6 from the permeable filter element 4 remain inside the flow meter body 1, when the drain valve 11 is opened, the liquid flows toward the impurity collecting pipe 9, thereby carrying the impurities into the impurity collecting pipe 9 and being discharged through the drain pipe 10, thereby completing the cleaning of the impurities.

[0043] Furthermore, the interior of the impurity collecting pipe 9 is rotatably connected with a rotating shaft 12, and a spiral blocking plate 13 is fixedly welded on the rotating shaft 12;

[0044] By setting the baffle plate 13, when the liquid flows through the sewage pipe 10, the force of the liquid flow causes the baffle plate 13 and the rotating shaft 12 to rotate. Therefore, the baffle plate 13 can continuously transport impurities downward through its own spiral shape, thereby avoiding the backflow phenomenon caused by impurities being left behind, thereby ensuring that the impurities will not cause secondary pollution to the permeable filter element 4.

[0045] Working principle: When the liquid passes through the permeable filter element 4, the impurities in the liquid are completely filtered out, which can effectively prevent the impurities from corroding and damaging the measuring elements of the flow meter body 1. At the same time, when the liquid flows, the driving force generated by the liquid flow drives the impeller ring 7 and the permeable filter element 4 to rotate together through the guide plate 8. Therefore, during the rotation of the permeable filter element 4, the bristle brush 6 continuously brushes the surface of the permeable filter element 4, thereby effectively avoiding its blockage, thereby ensuring the normal flow of the liquid, thereby ensuring the normal monitoring of the liquid flow by the flow meter body 1, thereby ensuring the normal use of the device and reducing the cost expenditure caused by maintenance and replacement.

[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
