[0030] Embodiment 1:

[0031] Figure 1 This is a schematic structural diagram of the flow detection device of the stirring rake described in an embodiment of the present application.

[0032] like Figure 1 As shown, the embodiment of the present application provides a flow detection device for a stirring rake, comprising:

[0033] The detection body 2 is used to connect with the stirring rake 7. A water-passing cavity corresponding to the structure of the stirring rake 7 is provided in the detection body 2. A water inlet interface 1 and a water return interface 4 are provided on the detection body 2.

[0034] The flow detection element 3 is installed on the pipe of the water return interface 4 and is used to detect the water flow of the stirring rake 7 flowing into the water passage cavity.

[0035] It should be noted that the water-passing cavity in the detection body 2 is an inner and outer double-layer structure, so that the water-passing cavity in the detection body 2 corresponds to the structure of the stirring rake 7. The flow detection element 3 is preferably a digital flowmeter, which is convenient for reading the detection data. The water inlet interface 1 is connected to the circulating water inlet pipe of the stirring rake 7, and the return water interface 4 is connected to the circulating water return pipe of the stirring rake 7. In the present embodiment, the water inlet interface 1 is connected to the circulating water inlet pipe of the stirring rake 7 and the return water interface 4 is connected to the circulating water return pipe of the stirring rake 7. Both are threaded connections, which are convenient for connection and installation. The flow detection device of the stirring rake is connected to the circulating water inlet pipe of the stirring rake through the water inlet interface and the return water interface is connected to the circulating water return pipe of the stirring rake, so that the circulating water of the stirring rake is consistent with the normal operating conditions, ensuring the effectiveness of the detection. The flow detection device of the stirring rake uses the flow detection element 3 to detect the water flow, so that the detection result is highly accurate.

[0036] In the embodiment of the present application, in order to fix the detection body 2 to the stirring rake 7 , a mounting hole 8 corresponding to the connection with the stirring rake 7 is opened on the detection body 2 .

[0037] It should be noted that the bolts are inserted through the mounting holes 8 into the stirring rake 7 to fix the detection body 2 to the stirring rake 7. In this embodiment, at least four mounting holes 8 are formed on the detection body 2.

[0038] In the embodiment of the present application, the cross-sectional area of ​​the water passage cavity is not less than the minimum water passage cross-sectional area of ​​the stirring rake 7 , so as to ensure the accuracy of the result of the flow detection element 3 detecting the water flow of the stirring rake 7 .

[0039] In the embodiment of the present application, the flow detection device of the stirring rake does not need to remove the stirring rake from the agitator to detect the water flow rate, and the flow detection device of the stirring rake has a simple structure. After the flow detection device of the stirring rake is connected to the stirring rake through the detection body, a flow detection element is used to detect the water flow of the stirring rake flowing into the water flow cavity, thereby realizing the detection of the water flow of the stirring rake. The detection is convenient and efficient, and the accuracy of the detection result is also ensured.

[0040] The present application provides a flow detection device for a stirring rake, comprising a detection body and a flow detection element. The detection body is used to connect with the stirring rake. A water-passing cavity matching the stirring rake structure is provided in the detection body. A water inlet interface and a water return interface are provided on the detection body. The flow detection element is installed on the pipe of the water return interface and is used to detect the water flow of the stirring rake flowing into the water-passing cavity. After the detection body is connected with the stirring rake, the flow detection device of the stirring rake uses the flow detection element to detect the water flow of the stirring rake flowing into the water-passing cavity, thereby realizing the detection of the water flow of the stirring rake. The detection is convenient and efficient, and the accuracy of the detection result is also ensured, solving the technical problems that the existing method of detecting the water flow of the stirring rake is troublesome to detect and the accuracy of the detection result is low.

[0041] like Figure 1 As shown, in one embodiment of the present application, a sealing connection member for sealing is provided at the connection between the detection body 2 and the stirring rake 4 , and the sealing connection member includes an inner sealing member 6 and an outer sealing member 5 .

[0042] It should be noted that the inner seal 6 and the outer seal 5 can be selected as O-rings of different specifications and sizes.

[0043] In the embodiment of the present application, during the detection, the flow detection device of the stirring rake connects the detection body 2 and the stirring rake 7 with bolts through the mounting hole 8, and seals them with the inner seal 6 and the outer seal 5. The water inlet interface 1 is connected to the circulating water inlet pipe, and the return water interface 4 is connected to the circulating water return pipe to form a complete detection water flow loop, thereby ensuring the effectiveness of the detection of the water flow of the stirring rake 7.

[0044] Embodiment 2:

[0045] Figure 2This is a flow chart of the steps of the flow detection method of the stirring rake described in the embodiment of the present application.

[0046] like Figure 2 As shown, the embodiment of the present application provides a flow detection method of a stirring rake, which is applied to the flow detection device of the stirring rake mentioned above, and the flow detection method includes:

[0047] S1. Get multiple mixing rakes in the same environment;

[0048] S2. The flow detection device is used to detect the flow of each stirring rake to obtain a plurality of measured water flow corresponding to the number of stirring rakes;

[0049] S3. If the differences between the values ​​of the plurality of measured water flow rates are all within the threshold range, the measured water flow rate is used as the water flow rate of the corresponding stirring rake.

[0050] It should be noted that the content of the flow detection device of the stirring rake in the second embodiment has been described in the embodiment, and the content of the flow detection device of the stirring rake will not be repeated in this second embodiment. In this embodiment, the threshold range can be set according to the requirements. Among them, the threshold range can be selected as ±0.3.

[0051] In an embodiment of the present application, the flow detection method of the stirring rake detects multiple stirring rakes in the same environment through the flow detection device of the stirring rake to obtain multiple measured water flow rates; then the multiple measured water flow rates are compared, and the comparison difference is within the threshold range, indicating that the measured water flow rate obtained by detection is valid and can be used as the water flow rate of the corresponding stirring rake.

[0052] In an embodiment of the present application, the flow detection method of the stirring rake also includes: if at least one of the differences between multiple measured water flow values ​​is not within a threshold range, the measured water flow is not used as the water flow of the corresponding stirring rake; or if multiple measured water flow values ​​are the same, the measured water flow is not used as the water flow of the corresponding stirring rake.

[0053] It should be noted that the flow detection method of the stirring rake uses a flow detection device to measure the flow of multiple stirring rakes respectively, and compares them to verify the effectiveness of the measurement. For example: the measured water flow of the 1# stirring rake is 2, and the measured water flow of the 2# stirring rake is 20. At this time, it can be determined that the measured water flow is invalid. For another example: the values ​​of the measured water flow of multiple stirring rakes are exactly the same, and they are all the same value. It can be determined that the measured water flow is also invalid. If the measured water flow of the 1# stirring rake is 2, the measured water flow of the 2# stirring rake is 2.1, and the measured water flow of the 3# stirring rake is 2.2, although there are small fluctuations in the measured water flow of multiple stirring rakes, it is also normal. At this time, it is considered that the measured water flow is valid.

[0054] In the embodiment of the present application, the ambient temperature of the stirring rake is the same, and when the water flow rate is the same, the heat taken away by the circulating water is equal, and the surface temperature of the stirring rake can be kept the same. If the flow rates are different, a large flow rate will take away more heat, resulting in a lower surface temperature, and a small flow rate will take away less heat, resulting in a higher surface temperature. Therefore, the flow rate detection method of the stirring rake can be used to compare the measured water flow rates of multiple stirring rakes horizontally to determine whether the surface temperature of the stirring rake is the same, providing data reference for the stability of the glass liquid and the further improvement of the glass quality during the glass manufacturing process. The flow rate detection method of the stirring rake can also be used to detect the flow rate of the stirring rake that has been put into use, and the measured water flow rate can be compared with the standard value to determine whether the stirring rake meets the basic use requirements and ensure the safe operation of the stirring rake.
