Description

Technical Field

[0001] This utility model belongs to the field of new energy battery technology, and specifically refers to a slurry resistance meter detection system and its detection structure. Background Technology

[0002] Slurries are typically mixtures of solid particles (such as metal powders and carbon black) dispersed in a liquid medium, and are widely used in industries such as electronics, batteries, and coatings. Resistance meters, by measuring the resistance of slurries, can assess their conductivity, thereby enabling the detection, monitoring, and control of slurry quality and performance. This ensures that the slurry's resistance characteristics meet design requirements, ultimately guaranteeing the performance of the final product.

[0003] In existing technologies, to ensure detection efficiency and accuracy, a circulating slurry is typically repeatedly passed through an energized detection module equipped with electrodes. The resistance of the slurry can be detected by changing the voltage input to the detection module. However, in practice, the surface area and smoothness of the channels within the detection module can affect the detection results.

[0004] Currently, the detection module body with channels is a large, integrated component, and it is milled in one go after the electrodes are assembled into a whole. Because the radius of the channels is relatively narrow and long, it is difficult to ensure the accuracy during milling, resulting in disadvantages such as difficult processing and low precision, which can easily lead to large deviations in the detection results. Furthermore, the integrated detection module body is pre-designed and processed according to production requirements, resulting in poor versatility in actual use and difficulty in coping with changing application environments. Utility Model Content

[0005] The main purpose of this utility model is to provide a slurry resistance meter detection system and its detection structure, which solves the problems existing in the prior art. It can be flexibly combined, improves the applicability of the scenario, and is easy to process and has high precision.

[0006] To achieve the above objectives, one of the solutions of this utility model is:

[0007] A slurry resistance meter detection structure includes a detection module composed of several sets of detection units that are detachably connected and coaxially arranged in sequence, and an input tube and an output tube that are detachably connected to both ends of the detection module. Each detection unit includes a detection body and two detection electrodes. A slurry channel is provided on the axis of the detection body, and a pair of opposing mounting holes are provided on both sides of the slurry channel. The detection ends of the two detection electrodes are inserted into the mounting holes so that the slurry flowing through the slurry channel contacts the detection ends. The two detection electrodes are electrically connected to the control circuit of the resistance meter via wires. A sealing ring is used to seal the adjacent end faces of the input tube, output tube, and detection body.

[0008] The input tube, output tube, and detection body are respectively provided with a first connecting ring, a second connecting ring, and a third connecting ring on the periphery of their end faces. The first connecting ring, the second connecting ring, and the third connecting ring have the same shape and size. The input tube and the detection body, the output tube and the detection body, and adjacent detection bodies are connected and fixed by clamps of the same specification. The clamps cover the periphery of the adjacent connecting rings.

[0009] The two ends of the detection body are respectively provided with positioning posts and positioning grooves at symmetrical positions. Adjacent detection bodies are connected and positioned by the positioning posts and positioning grooves that are embedded and cooperate.

[0010] Preferably, the end periphery of the positioning post is chamfered.

[0011] The inner side of the sealing ring extends upward and downward along its own axis to form sealing flanges; the end faces of the input pipe, output pipe, and detection body are respectively recessed to form a first annular groove, a second annular groove, and a third annular groove for the sealing flange to be embedded in; during assembly, the sealing flange is embedded in the corresponding annular groove and then fits against the outer wall of the annular groove.

[0012] The detection body has a recessed mounting groove on its circumferential surface, and the detection electrode has a positioning block that matches the mounting groove. The positioning block is embedded in the mounting groove.

[0013] Preferably, the positioning block of the detection electrode is fixed to the detection body by screws.

[0014] Preferably, the positioning block is disposed between the detection end and the connection end.

[0015] The second solution of this utility model is:

[0016] A slurry resistance meter detection system includes the aforementioned slurry resistance meter detection structure, as well as a slurry conveying main pipeline, a first switching valve, a second switching valve, and a third switching valve; the first switching valve is disposed on the slurry conveying main pipeline, and the second switching valve, the slurry resistance meter detection structure, and the third switching valve are sequentially connected to form a slurry conveying branch that connects to both ends of the first switching valve.

[0017] The first, second, and third switching valves are all electric valves; the third switching valve and the slurry resistance meter detection structure are equipped with an electromagnetic flowmeter; the slurry resistance meter detection system is mounted on a bracket and controlled and records data through a control device.

[0018] After adopting the above technical solution, the present invention has the following technical effects:

[0019] (1) The detection module of this utility model consists of several detection units. Each detection unit can be used with a resistance meter to perform independent slurry detection. Multiple detection units can perform detection at the same time to realize real-time detection of the resistance and its changes during the slurry flow process, making the detection results more accurate and reducing errors.

[0020] (2) Compared with the existing integrated detection module, after it is designed into several small detection units, the detection body of each detection unit has a smaller volume and size, and the corresponding slurry channel is shorter, easier to process, and has higher production efficiency.

[0021] (3) The detection units are connected in a detachable manner. When a detection unit is abnormal, it can be quickly replaced to restore detection. In addition, multiple detection units with different channel diameters can be combined according to actual needs, which is more flexible and free. Attached Figure Description

Detailed Implementation

[0028] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0029] refer to Figure 1-3As shown, this utility model discloses a slurry resistance meter detection structure, including a detection module composed of several sets of detection units that are detachably connected and coaxially arranged in sequence, and an input pipe 1 and an output pipe 2 (with reference to the slurry flow direction) detachably connected to both ends of the detection module. Figure 3 (Arrow direction)

[0030] The detection unit includes a detection body 3 and two detection electrodes 4; a slurry channel 31 is provided on the axis of the detection body 3, and a pair of opposing mounting holes 32 are provided on both sides of the slurry channel 31; the detection ends 41 of the two detection electrodes 4 are inserted into the mounting holes 32 so that the slurry flowing through the slurry channel 31 can contact the detection ends 41; the two detection electrodes 42 are electrically connected to the control circuit of the resistance meter through wires.

[0031] The adjacent end faces of the input tube 1, output tube 2, and detection body 3 are sealed by a sealing ring 5.

[0032] Through the above scheme, the detection module of this utility model consists of several detection units. Each detection unit can be used with a resistance meter to perform independent slurry detection. The simultaneous detection by multiple detection units can realize real-time detection of the resistance and its changes during the slurry flow process, making the detection results more accurate and reducing errors. Compared with the existing integrated detection module, after its separate design into several small detection units, the detection body 3 of each detection unit has a smaller volume and size, and therefore the corresponding slurry channel is shorter, easier to process, and has higher production efficiency. The detection units are connected in a detachable manner. When a detection unit malfunctions, it can be quickly replaced to restore detection. In addition, multiple detection units with different channel diameters can be combined according to actual needs, which is more flexible and free.

[0033] The following are specific embodiments of the present invention.

[0034] The input pipe 1, output pipe 2, and detection body 3 are respectively provided with a first connecting ring 11, a second connecting ring 21, and a third connecting ring 33 on their end faces. The first connecting ring 11, the second connecting ring 21, and the third connecting ring 33 have the same shape and size. The input pipe 1 and the detection body 3, the output pipe 2 and the detection body 3, and adjacent detection bodies 3 are connected and fixed by clamps 6 of the same specification. The clamps 6 cover the circumference of adjacent connecting rings. This improves the versatility of components and reduces assembly difficulty.

[0035] The two ends of the aforementioned detection body 3 are respectively provided with positioning posts 34 and positioning grooves 35 at symmetrical positions. Adjacent detection bodies 3 are connected and positioned by the embedded and matching positioning posts 34 and positioning grooves 35 to ensure that each slurry channel 31 is coaxial and to avoid the slurry from affecting the flow rate due to changes in the flow direction.

[0036] Furthermore, the end periphery of the aforementioned positioning post 34 is chamfered, making it easier for the positioning post 34 to be aligned and inserted into the positioning groove 35.

[0037] The inner side of the sealing ring 5 extends upward and downward along its own axis to form a sealing flange 51; the end faces of the input pipe 1, output pipe 2, and detection body 3 are respectively recessed to form a first annular groove 12, a second annular groove 22, and a third annular groove 36 for the sealing flange 51 to be embedded; during assembly, after the sealing flange 51 is embedded in the corresponding annular groove, it fits against the outer wall of the annular groove, thereby further improving the sealing effect in conjunction with the body of the sealing ring 5 and preventing slurry leakage.

[0038] The detection body 3 has a recessed mounting groove 37 on its circumferential surface. The detection electrode 4 has a positioning block 42 that matches the mounting groove 37. The positioning block 42 is embedded in the mounting groove 37 to fix the detection electrode 4 on the detection body 3, preventing the detection electrode 4 from rotating or shaking. In this embodiment, the positioning block 42 of the detection electrode 4 is locked to the detection body 3 by screws; the positioning block 42 is located between the detection end 41 and the connection end 42.

[0039] refer to Figure 4 As shown, this utility model also discloses a slurry resistance meter detection system, including the aforementioned slurry resistance meter detection structure, a main slurry conveying pipeline 7, a first switching valve 8, a second switching valve 9, and a third switching valve 10. The first switching valve 8 is installed on the main slurry conveying pipeline 7, and the second switching valve 9, the slurry resistance meter detection structure, and the third switching valve 10 are sequentially connected to form a slurry conveying branch connecting to both ends of the first switching valve 8. Therefore, by combining different opening and closing states of the first switching valve 8, the second switching valve 9, and the third switching valve 10, different flow directions and circulation times of the slurry can be controlled, thereby enabling a variety of testing methods.

[0040] The first switching valve 8, the second switching valve 9, and the third switching valve 10 mentioned above can be electric valves to realize intelligent control process.

[0041] The aforementioned third switching valve 10 and the slurry resistance meter detection structure are equipped with an electromagnetic flowmeter 20, which is used to detect the flow rate of the slurry.

[0042] The above-mentioned slurry resistance meter detection system is installed on a bracket 30 and controlled and recorded by a control device 40.

[0043] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
