Description

Technical Field

[0001] The utility model belongs to the technical field of measuring equipment, and specifically relates to a non-contact liquid-solid interface measuring equipment. Background Art

[0002] The solid-liquid interface generally refers to the interface between the liquid phase and the solid phase defined from a macroscopic scale during the solidification process. It is usually necessary to measure the liquid level height of the solid-liquid interface, usually using non-contact measurement equipment.

[0003] Usually, non-contact solid-liquid measuring equipment uses the photoelectric refraction principle for measurement. The position of the liquid-solid interface is calculated through the angular relationship between the incident light and the outgoing light (reflection). Traditionally, when measuring the liquid-solid interface, the incident light device is fixed at the position to be detected, and the calculation is realized by generating a light source and using the principle of the light source. In the actual operation process, when measuring, it is inconvenient to adjust the angle and height of the light source. Only the incident light can be used to emit the light source in the liquid level to obtain a set of angular refraction data. The detected data is relatively single and cannot be measured at different angles of the liquid level, which affects the comprehensiveness of the detection.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a non-contact liquid-solid interface measuring device.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] A non-contact liquid-solid interface measuring device comprises two mounting plates, the upper sides of the two mounting plates are fixedly connected to two groove plates, the inner walls of the two groove plates are slidably matched with threaded rods, the two threaded rods are threadedly matched with U-shaped blocks, the inner wall of one of the two U-shaped blocks is rotatably matched with a light source, and one side of the other side of the two U-shaped blocks is fixedly connected to a receiving member;

[0008] The inner walls of the two mounting plates are provided with a driving cavity, and the inner walls of the driving cavity are rotatably matched with a worm gear meshing with the two threaded rods. An adjustment groove is provided on one side of one of the two mounting plates, and a lifting box is slidably matched with the inner wall of the adjustment groove. A connecting rod is fixedly connected to the upper side of the lifting box, and a linkage mechanism is installed between the connecting rod and the light source component.

[0009] The inner wall of the lifting box is equipped with an adjustment mechanism.

[0010] Optionally, the linkage mechanism includes a slide rail fixedly connected to the lower side of the light source, and a sliding block slidably engaged with the slide rail and rotatably engaged with the connecting rod. When the connecting rod moves up and down, the push sliding block slides in the slide rail, causing the light source to flip in the U-shaped block, thereby achieving angle adjustment.

[0011] Optionally, the adjustment mechanism includes an elastic block that slides and elastically fits on the inner wall of the lifting box, a plurality of snap-fitting grooves provided on one side of the inner wall of the adjustment groove, and a fixed block that is fixedly connected to one side of the elastic block and fits with the snap-fitting groove. When the height of the lifting box needs to be adjusted, the elastic block moves to one side so that the fixed block is separated from the snap-fitting groove, and the lifting box can be moved up and down. When it moves to a suitable position, the elastic block can be loosened so that the fixed block is inserted into the corresponding snap-fitting groove again to be fixed.

[0012] Optionally, a handle is fixedly connected to one side of the worm, and the handle increases the convenience of operating the worm.

[0013] Optionally, an operating rod is fixedly connected to the other side of the elastic block, and an operating ring is fixedly connected to one end of the operating rod. The elastic block can be pulled through the operating rod by holding the operating ring, which increases the convenience of operating the elastic block.

[0014] Optionally, two guide grooves are provided on both sides of the inner wall of the adjustment groove, and the inner walls of the two guide grooves are slidably matched with guide blocks fixedly connected to the lifting box. When the lifting box moves up and down, the guide blocks slide in the guide grooves to increase the stability of the lifting box.

[0015] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0016] By setting up a lifting box, the lifting box can be moved up and down to drive the connecting rod to move up and down, thereby adjusting the irradiation angle of the light source. By rotating the worm gear to drive the threaded rod to rotate, the height of the U-shaped block can be adjusted, thereby adjusting the height of the light source made by the light source, and adjusting the incident light at various angles. Multiple sets of data can be measured, and the measurement accuracy can be increased through multiple sets of data.

When the worm 8 rotates, the threaded rod 3 can be driven to rotate through the worm wheel. Its structure is a prior art and is not an innovative part, so no further description is made.

[0031] An adjustment mechanism 13 is installed on the inner wall of the lifting box 10 .

[0032] The light source 5 is a photodetector photodiode of the model LSIPD-L0.1 produced by Beijing Minguang Technology Co., Ltd., which is a prior art and will not be described in detail here.

[0033] One aspect of the application of this embodiment is as follows: when in use, firstly, two mounting plates 1 are installed on both sides of the position to be detected, and the position of the lifting box 10 is adjusted by controlling the adjustment mechanism 13, so as to push the connecting rod 11 upward to push one side of the light source 5 to move, and the linkage mechanism 12 is used for transmission, so that the light source 5 rotates in the U-shaped block 4, so as to be adjusted to different angles, and the rotating worm 8 drives the corresponding threaded rod 3 to rotate, so that the threaded rod 3 pushes the U-shaped block 4 to move up and down, so as to adjust the emission height of the light source 5, so as to achieve the conversion of incident light at different angles during measurement, calculate the position of the solid-liquid interface, obtain multiple sets of data, and increase the accuracy of the measurement.

[0034] The calculation principle of the solid-liquid interface height in this embodiment is: Figure 5 As shown, the container contains the solution to be tested, the upper layer is the supernatant, the lower layer is the suspended sediment layer, and a liquid-solid interface is formed between the two layers.

[0046] and

[0047] It can be understood that there are two ways to obtain the refractive index n, including method one, measuring and calculating with a refractometer; and method two, directly measuring by experimental method.

After moving to a suitable position, the elastic block 131 can be loosened so that the fixed block 133 is inserted into the corresponding clamping groove 132 again for fixation.
