Description

Technical Field

[0001] The utility model relates to the technical field of chemical detection equipment, in particular to a temperature detection module, a detection plate and a heavy metal detector. Background Art

[0002] A heavy metal detector is usually used to measure the heavy metal content in a liquid. Most heavy metal detectors insert charged electrodes into the liquid and measure the content of certain heavy metals in the liquid through the electrodes. However, at different temperatures, the values ​​measured by the electrodes will have different results. If the influence of the actual temperature is ignored, the measurement results will be inaccurate. Therefore, the heavy metal detector generally needs to be equipped with a temperature detection device. Since the detection electrodes of the heavy metal detector will take up a lot of space above the detection plate, the temperature detection device cannot be installed above the detection plate. If the temperature detection device is set below the detection plate, the temperature measured by the temperature detection device is the temperature at the bottom of the test tube. The temperature at the bottom of the test tube has a large deviation from the temperature in the middle of the test tube, resulting in inaccurate temperature detection results. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to provide a temperature detection module, a detection plate and a heavy metal detector to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] A temperature detection module is provided with a test tube side;

[0006] The temperature detection module comprises:

[0007] Temperature detection installation structure;

[0008] A temperature detection probe fixed to the temperature detection mounting structure, wherein the temperature detection probe is configured as a contact temperature sensor and is provided with a detection end, wherein the detection end faces the test tube side;

[0009] The proximity drive structure has an output end that is fixed to the temperature detection installation structure, and the proximity drive structure is used to drive the temperature detection installation structure to move along a temperature detection direction.

[0010] Through the above technical solution, when it is necessary to perform temperature detection on the test tube, the temperature detection installation structure is driven by the driving structure to move along the temperature detection direction, so that the temperature detection probe is close to the test tube, and the detection end of the temperature detection probe abuts against the middle part of the test tube, so that the temperature of the middle part of the test tube can be measured, thereby reducing the temperature measurement error, which is beneficial to improving the accuracy of the detection results of the heavy metal detector.

[0011] As a further improvement of the above technical solution, the detection end is provided with an arc-shaped concave surface.

[0012] Through the above technical solution, by providing the arc-shaped concave surface, the detection end can be more closely attached to the side wall of the test tube, thereby increasing the accuracy of the temperature detection probe in detecting the temperature.

[0013] As a further improvement of the above technical solution, a chamfer is provided on the periphery of the detection end.

[0014] Through the above technical solution, by providing a chamfer on the periphery of the detection end, the sharp corners of the periphery of the detection end can be reduced, thereby avoiding the contact between the sharp corners and the side walls of the test tube when the detection end is close to the test tube, and effectively avoiding damage to the test tube caused by the sharp corners, thereby increasing the service life of the test tube.

[0015] As a further improvement of the above technical solution, the number of the temperature detection probes is set to multiple, and the multiple temperature detection probes are arranged in an arc shape.

[0016] Through the above technical solution, multiple temperature detection probes can detect the temperatures of multiple test tubes at the same time, which can reduce the overall detection time of the heavy metal detector to a certain extent.

[0017] As a further improvement of the above technical solution, the temperature detection installation structure is a fan-ring block structure.

[0018] As a further improvement of the above technical solution, the temperature detection probe is threadedly connected to the temperature detection mounting structure.

[0019] The detection plate is provided with a test tube jack and a temperature detection hole, the number of the test tube jack and the temperature detection hole are both set to multiple, and the two ends of the temperature detection hole are respectively connected to the test tube jack and the side wall of the detection plate.

[0020] Through the above technical scheme, the temperature detection probe can be extended into the temperature detection hole. Since the temperature detection hole is connected with the test tube jack, after the temperature detection probe is extended into the temperature detection hole, the detection end of the temperature detection probe will eventually abut against the side wall of the test tube. The abutment between the detection end of the temperature detection probe and the side wall of the test tube can realize the temperature measurement of the middle part of the test tube, thereby reducing the temperature measurement error, which is beneficial to improve the accuracy of the detection results of the heavy metal detector.

[0021] Heavy metal detector, including:

[0022] frame;

[0023] The detection plate as described above, wherein the detection plate is rotatably connected to the frame;

[0024] As described in any of the above temperature detection modules, the proximity drive structure is fixed to the frame, and the temperature detection module is arranged beside the detection plate.

[0025] Through the above technical scheme, when it is necessary to perform temperature detection on the test tube, the temperature detection installation structure is driven by the driving structure to move along the temperature detection direction, so that the temperature detection installation structure is close to the detection disk, and the temperature detection probe can be inserted into the temperature detection hole. Since the temperature detection hole is connected with the test tube jack, after the temperature detection probe is inserted into the temperature detection hole, the detection end of the temperature detection probe will eventually abut against the side wall of the test tube. The detection end of the temperature detection probe abuts against the side wall of the test tube, which can realize temperature measurement of the middle part of the test tube, thereby reducing the temperature measurement error, which is beneficial to improving the accuracy of the detection results of the heavy metal detector.

[0026] As a further improvement of the above technical solution, the temperature detection installation structure is provided with a first guide block, and the frame is fixed with a second guide block; the first guide block and the second guide block both extend along the temperature detection direction, and the side wall of the second guide block is always in contact with the side wall of the first guide block.

[0027] Through the above technical solution, the second guide block and the first guide block can guide the temperature detection installation structure to avoid deflection of the temperature detection installation structure during movement.

[0028] As a further improvement of the above technical solution, a plurality of the first guide blocks and a plurality of the second guide blocks are provided.

[0029] The beneficial effect of the utility model is that it is helpful to improve the accuracy of the detection result of the heavy metal detector.
