Technical Field

[0001] The utility model relates to the field of detection instruments, in particular to a spectrum layered detection device. Background Art

[0002] In the chemical industry, accurate detection and monitoring of the liquid phase is crucial to ensure the safety and efficiency of industrial production.

[0003] In current technology, the light source and visual inspection module are located on both sides of the mirror. The light source illuminates the mirror, and the visual inspection module on the other side takes the liquid phase image by using the light transmittance difference of different liquid phases, and uses the image recognition function to distinguish different liquid phases.

[0004] However, the existing devices are bulky and inconvenient to install. In addition, when encountering a liquid phase with high turbidity, the light path is difficult to penetrate the liquid phase, resulting in unclear images taken by the visual detection module, thereby increasing the difficulty of detection.

The connecting tube limits and fixes the lamp board, the focusing plate, and the reflective plate in the light source housing through a pressure ring and the annular boss.

[0010] In one embodiment, a circle of clamping groove is provided inwardly on the outside of the pressure ring, and the connecting tube has a clamping ring, which is clamped in the clamping groove.

[0011] In one embodiment, the inner circle of the focusing plate is in a cone barrel shape, and the inner diameter of the focusing plate tends to become smaller toward the reflective plate.

[0012] In one embodiment, the inner diameter of the reflective plate is smaller than the inner diameter of the focusing plate.

[0013] In one embodiment, the focusing plate is made of acrylic material.

[0014] In one embodiment, the reflective plate is made of mirror-finished stainless steel material, and the mirror surface of the reflective plate is on the side of the focusing plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The spectral layered detection device of the utility model makes the device smaller by arranging the light source module and the visual detection module on the same side; at the same time, materials with high turbidity can also be clearly imaged, thereby improving the detection accuracy of materials with high turbidity.

[0017] (2) The spectral layered detection device of the utility model can better focus the light emitted by the light board onto the reflective plate by setting the inner circle of the focusing plate to be a cone barrel shape whose inner diameter tends to become smaller towards the reflective plate, thereby avoiding light diffusion and improving the clarity of material imaging, thereby ensuring the detection accuracy of the material.

[0023] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0024] like Figure 1-4As shown, the utility model is a spectral stratification detection device, including: a light source module 2, a connecting tube 3, and a visual detection module 4; the light source module 2 is connected to the sight glass 1, and the visual detection module 4 is connected to the light source module 2 through the connecting tube 3, the light source module 2 emits light to the sight glass 1 to illuminate the material in the sight glass 1, and the visual detection module 4 is on the same side of the light source module 2, and it photographs the material in the sight glass 1 through the connecting tube 3 and the light source module 2. There are differences in the light transmittance of different phases of the liquid, so through the photographed image recognition, the stratification detection of the liquid phase is realized. The spectral stratification detection device of this embodiment makes the device smaller by arranging the light source module 2 and the visual detection module 4 on the same side; at the same time, the material with higher turbidity can also be clearly imaged, thereby improving the detection accuracy of the material with higher turbidity. Specifically:

[0025] The light source module 2 includes: a light source housing 21, an annular light board 22 in the light source housing 21 that emits light toward the visual detection module 4, an annular focusing plate 23 on the light-emitting side of the light board 22, and an annular reflector 24 on the focusing side of the focusing plate 23 for reflecting light to the viewfinder 1.

[0026] The light source housing 21 of the present embodiment is a hollow structure with a square outside and a round inside, and has an annular boss 211 inside one end thereof close to the viewfinder 1; the connecting tube 3 is a hollow structure with a square outside and a round inside, and has a snap ring 31 at one end thereof, and its outside is fixedly connected to the light source housing 21 by screws; a pressing ring 5 is provided between the light source housing 21 and the connecting tube 3, and a circle of slots 51 are provided on the outside of the pressing ring 5; the lamp board 22 is placed in the light source housing 21, and its non-luminous surface is fitted with the annular boss 211, and then the focusing plate 23 and the reflecting plate 24 are placed in sequence, and the snap ring 31 of the connecting tube 3 is clamped in the slot 51 outside the pressing ring 5, and then the pressing ring 5 is placed in the light source housing 21, and the connecting tube 3 and the light source housing 21 are locked by screws on the outside, so that the lamp board 22, the focusing plate 23, and the reflecting plate 24 are limited and fixed in the light source housing 21 by the pressing ring 5.

[0027] In this embodiment, the annular boss 211, the annular light plate 22, the annular focusing plate 23, and the annular reflector 24 form a channel in the center, and the visual inspection module 4 can photograph the material in the viewfinder 1 through the channel.

[0028] The inner circle of the condenser plate 23 of this embodiment is a cone barrel shape, and the inner diameter of the condenser plate 23 tends to decrease toward the reflector plate 24, and the inner diameter of the reflector plate 24 is smaller than the inner diameter of the condenser plate 23; the light path converges on the reflector plate 24 through the cone surface, and the reflective surface reflects the light to the mirror 1. By setting the inner circle of the condenser plate 23 to be a cone barrel shape with an inner diameter tending to decrease toward the reflector plate 24, the light emitted by the light board 22 can be better concentrated on the reflector plate 24, light diffusion can be avoided, and the clarity of material imaging is improved, thereby ensuring the detection accuracy of the material.

[0031] Working principle: The spectral layered detection device of this embodiment is installed on one side of the sight glass 1, the light board 22 emits light, the light path is focused by the focusing plate 23 to the reflector 24, and is reflected by the reflector 24 into the sight glass 1. The visual detection module 4 photographs the material in the sight glass 1 through the connecting tube 3 and the light source module 2, and utilizes the difference in light transmittance of different phases of the liquid to recognize the photographed image, thereby realizing layered detection of the liquid phase. The spectral layered detection device of this embodiment makes the device smaller by arranging the light source module 2 and the visual detection module 4 on the same side; at the same time, materials with higher turbidity can also be clearly imaged, thereby improving the detection accuracy of materials with higher turbidity.
