Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to an overflow structure with accurate measurement. Background Art

[0002] Overflow, overflow usually refers to the phenomenon of water overflowing, which is often encountered in industry and life. At present, most of the sewage treatment plants use overflow to discharge water; and gas will enter the overflow outlet pipe, causing the pipe to be not full. The installation condition of the electromagnetic flowmeter requires a full pipe without gas entering, otherwise it will cause the electromagnetic flowmeter to fluctuate and the measurement to be inaccurate.

[0003] Therefore, in response to this phenomenon, an overflow structure for electromagnetic flowmeters should be designed to ensure that the pipe is full of water. At the same time, a filtering structure that can be used for the overflow pipe should be designed to ensure the normal operation of the overflow pipe. Utility Model Content

[0024] Reference Figure 1-5 , an overflow structure with accurate measurement, comprising a water tank 1, an overflow port 101 is integrally provided on one side of the water tank 1, and the overflow port 101 is connected to an overflow pipe 4;

[0025] A precise measuring connection structure is provided on one side of the overflow pipe 4;

[0026] The interconnecting structure includes a U-shaped tube 2, an electromagnetic flowmeter 201, an exhaust pipe 3, a breathing valve 301, and a waterproof cap 304. A U-shaped tube 2 is provided on one side of the overflow pipe 4, and an electromagnetic flowmeter 201 is installed on the U-shaped tube 2. An exhaust pipe 3 is extended on one side of the U-shaped tube 2 near the overflow pipe 4, a breathing valve 301 is installed on the top of the exhaust pipe 3, and a waterproof cap 304 is installed on the outside of the top of the exhaust pipe 3; the electromagnetic flowmeter 201 can detect the flow inside the U-shaped tube 2.

[0027] A filter structure that is easy to replace is provided on the other side of the U-shaped tube 2 near the overflow port 101;

[0028] The filtering structure includes a clamp 5, a support member 501, a slider 6, a detachable pipe 7, a tightening bolt 701, an elastic surface 702, an air bag 7038, and a filter 8;

[0029] The U-shaped tube 2 is connected to a detachable pipe 7 through a fracture, and a support member 501 is fixedly installed on the U-shaped tube 2 near the fracture through a clamp 5, and a slider 6 is slidably connected to the support member 501 through a track; the slider 6 is fixedly connected to the detachable pipe 7, and the number of the detachable pipe 7 and the slider 6 is at least two groups, so that the slider 6 can be used to quickly replace the detachable pipe 7, and multiple groups of detachable pipes 7 can improve alternating use and improve efficiency, and will not be affected by cleaning the filter 8.

[0030] A tensioning bolt 701 is rotatably connected to the upper edge of the end of the detachable pipe 7. The detachable pipe 7 is arranged in two sections, and the middle part is connected by an elastic surface 702. There are symmetrical connecting ears 202 at the fracture of the U-shaped tube 2. The connecting ears 202 correspond to the tensioning bolts 701 in position and quantity, and the connecting ears 202 are connected to the tensioning bolts 701 through nuts. The tensioning bolts 701 are rotated to overlap the connecting ears 202, and the nuts are rotated at the same time, so that the detachable pipe 7 can be connected to the U-shaped tube 2. The elastic surface 702 ensures the displacement distance of the detachable pipe 7 and ensures the sealing performance.

[0031] The end of the detachable pipe 7 is tightly fitted with an airbag 703, and a groove corresponding to the airbag 703 is provided at the fracture of the U-shaped tube 2, and the airbag 703 is matched with a valve core, which extends out of the U-shaped tube 2. The airbag 703 is inflated and expanded to fit the groove, so that the gap between the detachable pipe 7 and the U-shaped tube 2 can be filled to improve the sealing performance. A filter screen 8 is embedded in the detachable pipe 7, and the filter screen 8 can filter out debris.

[0032] The highest point of the U-shaped tube 2 on the side close to the overflow port 101 is point b, and the lowest point at the connection between the U-shaped tube 2 and the overflow pipe 4 is point a. The horizontal plane at point a is higher than the horizontal plane at point b. This design utilizes the principle of a communicating vessel so that when the water tank 1 overflows, the water level of the water tank 1 is always higher than the water level of the overflow port 101. Air will no longer enter the U-shaped tube 2, ensuring that the U-shaped tube 2 is in a full tube state, thereby improving the measurement accuracy of the electromagnetic flowmeter 201.

[0033] Working principle: First, the water in the water tank 1 is discharged through the overflow port 101, the U-shaped pipe 2, and the overflow pipe 4. This design uses the principle of the communicating vessel. The horizontal plane at point a is higher than the horizontal plane at point b. When the water tank 1 overflows, the water level of the water tank 1 is always higher than the water level of the overflow port 101. The U-shaped pipe 2 will no longer enter the air, ensuring that the U-shaped pipe 2 is full, and improving the measurement accuracy of the electromagnetic flowmeter 201. In order to ensure the atmospheric pressure balance on both sides of the U-shaped pipe 2 where the flowmeter is installed, the breathing valve 301 of the exhaust pipe 3 can ensure gas circulation;

[0034] The detachable pipe 7 is replaced, and the fracture of the U-shaped tube 2 is symmetrically provided with connecting ears 202. The position and number of the connecting ears 202 correspond to the tightening bolts 701, and the connecting ears 202 are connected to the tightening bolts 701 through nuts. By rotating the tightening bolts 701 to overlap with the connecting ears 202, and rotating the nuts at the same time, the detachable pipe 7 can be pulled into connection with the U-shaped tube 2, and the elastic surface 702 ensures the displacement distance of the detachable pipe 7 and the sealing performance. At the same time, since a groove corresponding to the airbag 703 is provided at the fracture of the U-shaped tube 2, and the airbag 703 is equipped with a valve core, the valve core extends out of the U-shaped tube 2, and the airbag 703 is inflated and expanded to fit with the groove, the gap between the detachable pipe 7 and the U-shaped tube 2 can be filled to improve the sealing performance. A filter screen 8 is embedded in the detachable pipe 7, and the filter screen 8 can filter debris.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
