[0002] In the national standard testing procedure for total cyanide, it is necessary to collect and quantify the cooled runoff. How to achieve this function has been a subject of ongoing research. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a total cyanide measuring device to solve the aforementioned technical problems.

[0004] To achieve the aforementioned objectives, this utility model provides the following technical solution:

[0005] A total cyanide measuring device includes a colorimetric holder, a colorimetric tube, a measuring lamp, a fiber optic collimator, a receiving sensor, and a light guide column. The colorimetric holder includes a holder body and a holder sub-body, which are connected and form a first angle between them. The colorimetric tube includes a colorimetric tube body and a colorimetric tube sub-body, which are connected. The colorimetric tube body is fixed to the holder body, and the colorimetric tube sub-body is fixed to the holder sub-body, such that a first angle is formed between the colorimetric tube body and the colorimetric tube sub-body. The second included angle; the measuring lamp is installed at the top of the support body, the fiber optic collimator is disposed between the measuring lamp and the colorimetric tube body; the receiving sensor is installed at the bottom of the support body, the light guide column is disposed between the receiving sensor and the colorimetric tube body; the bottom of the colorimetric tube body has a liquid inlet on the side near the support sub-body, and the bottom of the colorimetric tube body has a liquid outlet corresponding to the position of the liquid inlet, the liquid outlet and the colorimetric tube body forming a third included angle.

[0006] Preferably, the axis of the light guide column is positioned on the side closer to the liquid outlet relative to the axis of the colorimetric tube body; the measuring lamp, fiber optic collimator, light guide column, and receiving sensor are all correspondingly positioned.

[0007] Preferably, the measuring lamp, fiber optic collimator, light guide, and receiving sensor are located in a straight line.

[0008] Preferably, a three-way valve is installed on the liquid inlet. One port of the three-way valve is connected to the liquid inlet, and the other port is used to connect to the distillation tank.

[0009] Preferably, the colorimetric tube body is tilted when in use.

[0010] Preferably, the third included angle is greater than 116° and less than 148°; the first included angle is greater than 116° and less than 148°.

[0011] The second included angle is greater than or equal to the first included angle; the tilt angle of the colorimetric tube body relative to the horizontal plane is greater than 26° and less than 48°.

[0012] Preferably, the third included angle is a right angle; the liquid inlet is arranged perpendicular to the body of the colorimetric tube;

[0013] The first included angle is 45°; the second included angle is equal to the first included angle;

[0015] Preferably, an overflow port is provided at the top of the colorimetric tube sub-body; a reference sensor is installed on the side of the bracket body corresponding to the measuring lamp.

[0016] The total cyanide measuring device provided by this invention involves first adding a measured amount of alkaline solution as an absorbent, covering the inlet of the colorimetric tube. During distillation, the distillation tank is slowly aerated, allowing cyanide gas and the distillate to slowly enter the colorimetric tube. As the cyanide gas and distillate enter the colorimetric tube, the measuring lamp is turned on. The light emitted by the measuring lamp passes through a fiber optic collimator and enters the colorimetric tube, then is guided to the receiving sensor by a light guide column. Initially, due to reflection and refraction at the liquid surface, most of the light is lost, and the receiving sensor receives a certain amount of light intensity. When the distillate reaches the top of the colorimetric tube, the liquid level is higher than the light emitted by the measuring lamp, eliminating interference from reflection and refraction. The light intensity value of the receiving sensor will then change abruptly, at which point the distillate entry into the colorimetric tube can be stopped, completing the quantitative operation of the distillate. The distillate can be collected through the outlet after cooling. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1, please refer to Figure 1 The total cyanide measuring device in this embodiment includes a colorimetric support, a colorimetric tube, a measuring lamp 30, a fiber optic collimating lens 40, a receiving sensor 50, and a light guide column 60. The colorimetric support includes a support body 11 and a support sub-body 12, which are connected and form a first angle between them. The colorimetric tube includes a colorimetric tube body 21 and a colorimetric tube sub-body 22, which are connected. The colorimetric tube body is fixed to the support body, and the colorimetric tube sub-body is fixed to the support sub-body, such that the colorimetric tube body and the colorimetric tube sub-body are connected. A second included angle is formed between the colorimetric tube bodies; the measuring lamp is mounted at the top of the support body, and the fiber optic collimator is positioned between the measuring lamp and the colorimetric tube body; the receiving sensor is mounted at the bottom of the support body, and the light guide is positioned between the receiving sensor and the colorimetric tube body; a liquid inlet 23 is provided at the bottom of the colorimetric tube body on the side near the support body, and a liquid outlet 24 is provided at the bottom of the colorimetric tube body corresponding to the position of the liquid inlet, forming a third included angle between the liquid outlet and the colorimetric tube body. In use, the colorimetric tube body should be tilted. The third included angle is greater than 116° and less than 148°; the first included angle is greater than 116° and less than 148°.

[0022] The second included angle is greater than or equal to the first included angle; the inclination angle of the colorimetric tube body relative to the horizontal plane is greater than 26° and less than 48°. Preferably, the third included angle is a right angle; the liquid inlet is perpendicular to the colorimetric tube body.

[0023] The first included angle is 45°; the second included angle is equal to the first included angle; the inclination angle of the colorimetric tube body relative to the horizontal plane is 45°. In actual manufacturing, the top of the colorimetric tube sub-body is provided with an overflow port, the main function of which is to communicate with the air to facilitate pressure relief; another function is overflow, so that when there is too much liquid in case of failure or during cleaning, some liquid can be discharged; it can also be connected to an anti-backflow absorption bottle to prevent toxic gases that may not be absorbed by the absorption liquid from overflowing under acidic conditions.

[0024] In use, the above-mentioned total cyanide measuring device has an inlet port for connecting to the distillation tank and an outlet port for collecting the cooled effluent. During manufacturing, a valve can also be connected to the outlet for control. Before distilling the total cyanide, a measured amount of alkaline solution is added as an absorbent, covering the effluent inlet of the colorimetric tube. During distillation, the distillation tank is slowly aerated, and cyanide gas and effluent slowly enter the colorimetric tube. When the cyanide gas and effluent enter the colorimetric tube, the measuring lamp 30 is turned on. The light emitted by the measuring lamp passes through the fiber optic collimator 40 and enters the colorimetric tube, then is guided to the receiving sensor 50 by the light guide column 60. Initially, due to reflection and refraction of the liquid surface, most of the light is lost, and the receiving sensor 50 receives only a small amount of light. The quantitative light intensity is determined when the distillate reaches the top of the colorimetric tube. The liquid level is higher than the light emitted by the measuring lamp, eliminating interference from reflection and refraction. This causes a sudden change in the light intensity value of the receiving sensor 50, at which point the distillate can be stopped from entering the colorimetric tube, completing the quantitative operation of the distillate. In practical use, a three-way valve is preferably installed on the inlet port. One port of the three-way valve is connected to the inlet port, another port is connected to the distillation tank, and the third port is used to prevent liquid in the colorimetric tube from being backflowed into the distillation tank when it is being cooled.

[0025] In a preferred embodiment, a reference sensor 70 is mounted on the side of the bracket body corresponding to the measuring lamp. The reference sensor 70 facilitates the subsequent measurement process, which is well known to those skilled in the art and will not be described in detail here.

[0026] In a preferred embodiment, the axis of the light guide column is positioned relative to the axis of the colorimetric tube body, closer to the liquid outlet. The measuring lamp, fiber optic collimator, light guide column, and receiving sensor are also correspondingly positioned, and can be aligned in a straight line during manufacturing. This creates an eccentric optical path during measurement; after the cyanide gas enters the colorimetric tube body, it floats upwards within the liquid and moves along the optical path. The bubble path and the optical path are completely separated, preventing interference caused by reflection and refraction when the light passes through the bubble.
