Description

Technical Field

[0001] This invention relates to the field of wastewater testing technology, and in particular to a high-efficiency wastewater quality testing device. Background Technology

[0002] Wastewater testing devices are commonly used to monitor various pollutants in wastewater so that timely treatment measures can be taken to ensure environmental safety. Depending on the parameters monitored, wastewater testing devices can be classified into different types. Utilizing optical methods, such as visible light, infrared light, and ultraviolet light, to detect water quality is a common existing method. This mainly relies on the absorption, scattering, and emission characteristics of light by different substances in the water. Different wavelengths of light interact with different substances in the water, which can be used to identify pollutants or other components. Among these, laser absorption method utilizes the absorption characteristics of laser beams by substances in the water. By comparing the intensity of the original laser with the intensity of the laser transmitted through the water sample, the characteristics of dissolved substances or suspended particles in the water can be inferred. However, existing detection devices using laser detection cannot effectively block large particles in the water sample, and the uneven distribution of particles in the water sample, along with imperfect control over the release and collection of water samples, leads to a cumbersome detection process and inaccurate results. Therefore, this invention proposes a detection device that solves the above-mentioned technical problems. It is easy to operate, allows for quick replacement of water samples in the detection area, can block large particles, and ensures a uniform distribution of impurity particles in the water sample, thus improving detection accuracy.

[0031] Operating principle: In the detection area, the take-up and release cylinder 4 can be rotated by the take-up and release motor 5 to control the take-up and release of the take-up and release rope 6, thereby controlling the release depth of the control cylinder 7; by cooperating with the control cylinder 13 to control the movement of the water sample filter cylinder 15, the bottom end of the water sample filter cylinder 15 separates from the bottom end of the control cylinder 7, and the water sample can enter the interior of the control cylinder 7 through the water sample filter cylinder 15. The water sample filter cylinder 15 can block large suspended particles to avoid affecting the emission and reception of lasers; after the water sample enters the interior of the control cylinder 7, the water sample filter cylinder is controlled to... 15 is sealed to the bottom of the control cylinder 7. The water sample is inside the control cylinder 7. The motor 23 can be used to rotate the stirring gear ring 20, that is, the stirring rod 21 can stir the water sample, so that the suspended particles are evenly distributed, thereby improving the detection accuracy. The position slide 10 can be moved by the control cylinder 9 to change the distance between the laser emitter and receiver. The laser emitter 12 emits a laser, which passes through the water sample and is received by the laser receiver 18. In this way, the characteristics of dissolved substances or suspended particles in the water can be analyzed to complete the detection.

[0032] Specifically, the depth of the control cylinder 7 can be controlled, and the detection area can be changed, enabling convenient and efficient water sample replacement. After one detection is completed, the control cylinder 7 can be raised above the water layer, or the water sample can be released in the water by separating the water sample filter cylinder 15 from the bottom of the control cylinder 7. Specifically, the motor 14 can be used to rotate the scraping toothed ring 30, thereby causing the outer scraper 31 and inner scraper 32 to scrape the outer and inner sides of the water sample filter cylinder 15, thus removing impurities adhering to the water sample filter cylinder 15. To reduce the impact on subsequent testing; for the agitation operation of the outer scraper 31 and the inner scraper 32, when the water sample filter 15 is separated from the bottom of the control cylinder 7, the pusher 36 releases the pusher seat 35, causing the limiting seat 33 to extend and retract and cooperate with the outer scraper 31, thereby restricting and fixing the outer scraper 31 and the inner scraper 32, preventing the outer scraper 31 and the inner scraper 32 from rotating. When the water sample filter 15 is resealed and connected to the bottom of the control cylinder 7, the gear 29 can mesh with the scraping gear ring 30, and the limiting seat 33 releases the restriction and fixing of the outer scraper 31.

[0033] To prevent suspended particulate matter from adhering to the laser emission and reception path, i.e., to the light-transmitting shield 11 or the light-transmitting shield 17, the height of the position cylinder 27 can be controlled by the position cylinder 25, and the position cylinder 27 controls the radial position of the scraper 28, so that the scraper 28 scrapes the surface of the light-transmitting shield 17. The scraping can be achieved in conjunction with the rotation of the agitator ring 20. The height of the light-transmitting shield 11 can be controlled by the control cylinder 9 to complete the scraping operation of the light-transmitting shield 11.
