Description

Technical fields:

[0001] This utility model relates to the field of fluid detection technology, and in particular to an online electrolyte detector. Background technology:

[0002] Electrolyte is the medium used in chemical batteries, electrolytic capacitors, and other electronic devices. It provides ions for their normal operation and ensures the chemical reactions that occur during operation. During the recycling process, to ensure the quality and stability of the electrolyte, its transparency and turbidity need to be tested. Traditional testing methods typically use syringe pumps, which require completely draining the original electrolyte before drawing in new liquid to begin testing. This is cumbersome and inefficient. While online testing equipment has improved efficiency to some extent, over time, some electrolyte adheres to the tube walls. As the amount of deposits on the tube walls increases, if these deposits are not cleaned promptly, they will affect the testing accuracy. Currently, there is no good solution to this problem.

[0003] In summary, how to clean the deposits on the pipe walls of online testing equipment in a timely manner to ensure testing accuracy has become a technical problem that urgently needs to be solved in the industry. Utility model content:

[0004] To overcome the shortcomings of existing technologies, this utility model provides an online electrolyte detector, which solves the problems of cumbersome operation and low detection efficiency of previous injection pumps, and also solves the problem that the deposits on the tube walls of previous online detection equipment were difficult to clean and affected the detection accuracy.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An online electrolyte detector includes a housing, within which a transparent glass tube is disposed. The top of the transparent glass tube has an upper cap, and the upper cap contains a liquid inlet. A light source is disposed on one side of the transparent glass tube, and a sensor is disposed on the other side, with the sensor and light source positioned opposite each other. A piston is disposed inside the transparent glass tube, connected to a piston rod. A lower cap is disposed at the bottom of the transparent glass tube, and the piston rod extends downward through the lower cap to the outside. The bottom of the piston rod is connected to a drive mechanism. The piston rod is hollow inside, and a connecting hole is provided on the piston. The connecting hole is connected to the top end of a connecting pipe, which extends downward through the piston rod and its bottom end is connected to a liquid outlet located at the bottom of the housing.

[0007] The casing is a black, fully enclosed casing.

[0008] The transparent glass tube is sealed and fixed to both the upper and lower end caps.

[0009] The flange of the upper end cover is fixedly connected to the top of the housing by bolts.

[0010] The sensor is a photoelectric sensor.

[0011] Several sealing rings are provided between the piston and the transparent glass tube for sealing.

[0012] The drive mechanism includes a motor installed inside the housing. The output shaft of the motor is connected to a vertically installed lead screw. The motor, lead screw, transparent glass tube, and piston rod are isolated by a partition vertically installed inside the housing. The bottom of the piston rod is connected to a horizontal linkage plate. The partition is provided with a guide groove for guiding the horizontal linkage plate up and down. The other end of the horizontal linkage plate is threadedly connected to the lead screw.

[0013] The connecting pipeline uses PFA flexible tubing.

[0014] The liquid outlet is located inside the temperature sensor holder at the bottom of the housing, and a temperature sensor connected to the liquid outlet is installed on the temperature sensor holder.

[0015] The temperature sensor mount, upper cover, and piston are all made of PTFE material.

[0016] The present invention adopts the above solution and has the following advantages:

[0017] By placing a transparent glass tube inside the housing, with a light source on one side and a sensor on the other, the sensor and light source are positioned opposite each other. Electrolyte flows in from the liquid inlet, passes through the transparent glass tube, and flows out from the connecting hole, connecting pipe, and liquid outlet. The light emitted by the light source passes through the electrolyte and is received by the sensor, thus enabling real-time online detection of parameters such as the transparency and turbidity of the electrolyte without interruption, resulting in high detection efficiency. When the drive mechanism drives the piston to reciprocate, it can effectively remove residual liquid from the inner wall of the transparent glass tube, ensuring the transparency of the transparent glass tube and making the detection results more accurate and ensuring detection precision.

Detailed implementation method:

[0021] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] like Figure 1-2 As shown, an online electrolyte detector includes a housing 1, inside which is a transparent glass tube 2. The top of the transparent glass tube 2 is provided with an upper end cap 3, and the upper end cap 3 is provided with a liquid inlet 4. A light source 5 is provided on one side of the transparent glass tube 2, and a sensor 6 is provided on the other side. The sensor 6 and the light source 5 are placed facing each other. The structure is compact and small in size. Inside the transparent glass tube 2, there is a piston 7. The bottom of the piston 7 is connected to a piston rod 8. The bottom of the transparent glass tube 2 is provided with a lower end cap 9. The piston rod 8 extends downward through the lower end cap 9 to the outside. The bottom of the piston rod 8 is connected to a drive mechanism. The piston rod 8 is hollow inside. The piston 7 is provided with a connecting hole 10, which is connected to the top of a connecting pipe 11. The connecting pipe 11 extends downward through the piston rod 8 and its bottom end is connected to a liquid outlet 12 located at the bottom of the housing 1.

[0023] The housing 1 is a black, fully enclosed housing to prevent external light from entering and affecting the test results.

[0024] The transparent glass tube 2 is sealed and fixed to the upper end cap 3 and the lower end cap 9 to prevent liquid leakage.

[0025] The flange of the upper end cover 3 is fixedly connected to the top of the housing 1 by bolts, which can realize the installation and fixation of the transparent glass tube 2.

[0026] The sensor 6 is a photoelectric sensor. When the photoelectric sensor detects the transparency and turbidity of a liquid, the principle is that the light emitted by the light source passes through the liquid being measured, is partially absorbed by the liquid, and then reaches the photoelectric element. The amount of absorption depends on parameters such as the transparency and turbidity of the substance being measured.

[0027] The piston 7 and the transparent glass tube 2 are sealed with several sealing rings 13.

[0028] The driving mechanism includes a motor 14 installed inside the housing 1. The output shaft of the motor 14 is connected to a vertically installed lead screw 15. The motor 14, lead screw 15, transparent glass tube 2, and piston rod 8 are isolated by a partition 16 vertically installed inside the housing 1. The bottom of the piston rod 8 is connected to a horizontal linkage plate 17. The partition 16 has a guide groove 18 that guides the horizontal linkage plate 17 up and down. The other end of the horizontal linkage plate 17 is threadedly connected to the lead screw 15. When the motor 14 is working, it can drive the lead screw 15 to rotate. Since the lead screw 15 is threadedly connected to the horizontal linkage plate 17, the horizontal linkage plate 17 will move up and down under the restriction of the guide groove 18, thereby driving the piston rod 8 to move up and down. The piston rod 8 then drives the piston 7 to reciprocate up and down.

[0029] The connecting pipe 11 is made of PFA hose, which is highly corrosion resistant and can extend and retract with the piston 7 as it moves up and down, facilitating the flow of liquid.

[0030] The liquid outlet 12 is located inside the temperature sensor base 19 at the bottom of the housing 1. A temperature sensor 20 connected to the liquid outlet 12 is installed on the temperature sensor base 19 for real-time monitoring of the liquid temperature.

[0031] The temperature sensor base 19, the upper cover 3, and the piston 7 are all made of PTFE material, and all pipe joints are made of ETFE material, which has high corrosion resistance.

[0032] Working principle:

[0033] During operation, the electrolyte flows in from the liquid inlet 4, passes through the transparent glass tube 2, and then flows out from the connecting hole 10, connecting pipe 11, and liquid outlet 12. The light emitted by the light source 5 passes through the transparent glass tube 2 and the electrolyte and is received by the sensor 6, thereby enabling real-time online detection of parameters such as the transparency and turbidity of the electrolyte without interruption, resulting in high detection efficiency. During the detection process, or when changing to a new detection liquid, the piston 7 can be driven up and down by the drive mechanism to effectively remove residual liquid from the inner wall of the transparent glass tube 2, ensuring the transparency of the transparent glass tube 2 and making the detection results more accurate. Users can set the movement interval of the piston 7 according to the cleanliness of the detection liquid to ensure the accuracy and efficiency of the detection results.

[0034] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0035] Any aspects of this utility model not described in detail are known to those skilled in the art.
