Abstract
Description
Technical Field
[0001] This utility model relates to a water quality heavy metal detection pretreatment device, specifically a highly efficient digestion water quality heavy metal detection pretreatment device, belonging to the field of water quality detection technology. Background Technology
[0002] In the process of heavy metal detection in water quality, the pretreatment and digestion of water samples is a crucial step. Its purpose is to break down the organic matter in the water sample so that the heavy metal elements exist in a detectable form, thereby ensuring the accuracy and reliability of subsequent test results.
[0003] A pretreatment device for heavy metal detection in drinking water, disclosed in Chinese Patent Application Publication CN215262710U, includes a treatment tank, a mounting frame above the treatment tank, a magnetizer above the mounting frame, and a water sample container placed on top of the magnetizer. A water guide pipe is located at the center of the magnetizer, and two sets of opposing magnets with different magnetic poles are mounted on the outside of the water guide pipe. This technical solution solves the technical problems of existing pretreatment devices being unable to excite the sample to a high-energy state, resulting in low monitoring accuracy, and the tendency to produce scale over long periods, further reducing the treatment effect. It has broad application value in the field of water quality testing technology. However, this pretreatment device for heavy metal detection can only excite drinking water samples to a high-energy state for testing, but it cannot uniformly heat the water sample, leading to uneven and incomplete digestion of the water sample, thus affecting the accuracy of subsequent detection.
[0004] Therefore, a highly efficient water pretreatment device for heavy metal detection is proposed. Utility Model Content
[0005] This invention proposes a highly efficient water pretreatment device for heavy metal detection, which solves the problem that existing technologies cannot uniformly heat and digest water samples.
[0006] This utility model is achieved through the following technical solution: a water quality heavy metal detection pretreatment device with high efficiency digestion, including a pretreatment cylinder, wherein a uniform heating mechanism is provided both below and inside the pretreatment cylinder. The uniform heating mechanism includes a lower mounting base plate located below the pretreatment cylinder. A stirring motor is fixedly connected to the upper surface of the lower mounting base plate. The output end of the stirring motor passes through the pretreatment cylinder and extends into its interior. A rotating disk is fixedly connected to the output end of the stirring motor. Equally spaced circumferentially arranged scraper plates are fixedly connected to the outer surface of the rotating disk. The bottom surface of each scraper plate is in contact with the inner bottom wall of the pretreatment cylinder. A mounting frame is fixedly connected to the side of several scraper plates that are far apart from each other. The mounting frame is rotatably connected to the interior of the pretreatment cylinder. Equally spaced heating rods are fixedly connected to the upper surface of each scraper plate. Two sets of movable scraper plates are fixedly connected to the outer surface of each set of heating rods. A connecting frame is fixedly connected to the inner wall of the pretreatment cylinder. A multi-layer arc-shaped heating plate is fixedly connected to the bottom surface of the connecting frame. Each set of movable scraper plates is slidably connected to the interior of the multi-layer arc-shaped heating plate. The upper surface of each scraper plate is in contact with the bottom surface of the multi-layer arc-shaped heating plate. An atomization detection component is provided both below and on the front of the pretreatment cylinder, and a top cover component is provided above the uniform heating mechanism.
[0007] The atomization detection assembly includes a detection cylinder, the back of which is fixedly connected to the outer surface of the pretreatment cylinder, a data display screen fixedly connected to the front of the detection cylinder, the data display screen being connected to the detection cylinder via wires, an exhaust pipe fixedly connected to the upper surface of the detection cylinder, an atomizer fixedly connected to the bottom surface of the detection cylinder, and a connecting pipe fixedly connected to the bottom surface of the pretreatment cylinder, the output end of which is fixedly connected to the input end of the atomizer.
[0008] The top cover assembly includes an upper top cover, which is threadedly connected to the inside of the pretreatment cylinder, and two lifting handles are fixedly connected to the upper surface of the upper top cover.
[0009] The upper surface of the top cover is fixedly connected to a sampling and delivery tube, and a sealing plug is snapped into the inside of the sampling and delivery tube.
[0010] The bottom surface of the pretreatment cylinder is fixedly connected to a water sample discharge pipe, and the output end of the water sample discharge pipe is fixedly connected to a switch valve.
[0011] The bottom surface of the pretreatment cylinder is fixedly connected to two sets of support legs. The bottom end of each set of support legs is fixedly connected to a support chassis. The upper surface of each set of support chassis is fixedly connected to the bottom surface of the lower mounting plate. The outer surface of one set of support chassis is fixedly connected to the back of the atomizer.
[0012] This invention provides a highly efficient water pretreatment device for heavy metal detection, which has the following beneficial effects: This highly efficient water pretreatment device for heavy metal detection utilizes a stirring motor fixed on the base plate to drive a rotating disk, scraper, and mounting frame to rotate within the pretreatment cylinder. This facilitates scraping and stirring of the water sample at the bottom of the pretreatment cylinder. A heating rod fixed on the scraper and a movable scraper are used to heat the water sample within the pretreatment cylinder. The movable scraper further scrapes the water sample within the multi-layered arc-shaped heating plate fixed by the connecting frame. This allows for uniform heating and digestion of the water sample from the inside out, resulting in thorough and uniform digestion and improving the accuracy of heavy metal detection in the water.
[0013] This highly efficient water quality heavy metal detection pretreatment device can use a connecting pipe to transport a thoroughly digested water sample in the pretreatment cylinder to an atomizer for atomization. The temperature of the thoroughly digested water sample in the pretreatment cylinder is relatively high, which can result in a higher degree of atomization, thereby facilitating the detection of heavy metals in the water sample using a detection cylinder and further improving the accuracy of heavy metal detection in the water.
