Description

Technical Field

[0001] The invention relates to the technical field of wastewater detection, in particular to a visual detector for heavy metal ions in wastewater. Background Art

[0002] Wastewater refers to the collective term for water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other unused water such as primary rainwater runoff into drainage channels. It generally refers to water that cannot be recycled after undergoing certain technical treatments, or that cannot meet certain standards for purification after primary pollution. Heavy metals are a class of metallic elements with high density and toxicity. They are not easily degraded in the environment and tend to accumulate in organisms. When the heavy metal content in sewage exceeds a certain limit, it can damage aquatic ecosystems, affecting the growth and reproduction of aquatic organisms and even causing death. Furthermore, heavy metals can accumulate in the human body through the food chain, posing a serious threat to human health. Therefore, monitoring the heavy metal content in sewage is of great significance to protecting the environment and human health. The importance of heavy metal ion detection in wastewater is also reflected in the following aspects. The heavy metal ion content in wastewater needs to be detected during treatment. At this time, a heavy metal ion detector is needed. The heavy metal ion visualization detector is an instrument used to quickly and accurately detect the heavy metal ion content in water, soil, food and other samples. By adding a color developer to the collected material, the heavy metal ions in the collected material are colored, so that the heavy metal ion metals in the wastewater can be visualized.

[0003] The public number CN113640091A is a heavy metal ion detector for chemical plant wastewater, which includes a sampling box, a sampling component, a wastewater pretreatment box and a detection component; the sampling component includes a water tank and a piston cylinder equidistantly arranged in the sampling box, and the water tank is connected to the wastewater pretreatment box; the wastewater pretreatment box is used to transport the wastewater to the water tank after preliminary treatment, and the piston cylinder is used to transport the water in the water tank to the detection component; the detection component includes multiple groups of detection heads and detection water tanks, and flocculants are added to the wastewater pretreatment box to gather large particles of impurities in the wastewater and then filter them to avoid some large particles of impurities in the wastewater from causing blockage of the piston cylinder and the detection component, and to avoid some other impurities affecting the detection results. The results after detection by multiple groups of detection heads are compared to obtain more accurate detection results compared with traditional repetitive sampling detection.

[0004] However, based on the actual use process, the wastewater needs to be collected in advance and then tested. During this process, the wastewater needs to be collected first and then transported to the testing instrument for testing. The wastewater cannot be tested directly on site, resulting in low detection efficiency. Summary of the Invention

[0024] (1) This solution sets up a heavy metal ion collection mechanism and a mixing and filling mechanism, and puts the mounting frame into the wastewater where heavy metal ions need to be collected. The high-pressure air pump is used to extract air to collect the sludge and liquid in the wastewater. When the high-pressure air pump is running, the color developer inside the liquid storage tank can be drawn into the discharge pipe, and then flows from the discharge port to the circulation tank to mix with the collected material inside the circulation tank.

[0057] In some embodiments, see Figure 10 、 Figure 11 The storage mechanism includes a handle 202, a filter rack 204 and a filter screen 2041. A mounting groove 201 is provided on one side of the detector housing 1. The collection box 2 is slidably connected to the inside of the mounting groove 201. The filter rack 204 is fixedly installed on the inner wall of the collection box 2. The filter screen 2041 is fixedly installed on the inside of the filter rack 204. The handle 202 is fixedly installed on one side of the collection box 2. A material guide groove 105 is provided on one side of the conveying groove 104. One end of the material guide groove 105 is connected to the conveying groove 104, and the other side of the material guide groove 105 is connected to the mounting groove 201.

By setting the handle 202, the collection box 2 can be pulled out to the outside of the mounting groove 201 by pulling the handle 202.

[0058] It can also make the collection box 2 more convenient to install. The filter rack 204 occupies half of the space inside the collection box 2, and the filter rack 204 is located on one side of the material guide trough 105. By arranging a filter screen 2041 inside the filter rack 204, when the collection flow inside the material guide trough 105 flows into the collection box 2, the sludge in the collection will remain on the top of the filter screen 2041, and the liquid in the collection will flow to the bottom of the collection box 2 through the filter screen 2041, so that the sludge and liquid in the collection can be stored separately, which is convenient for observing the heavy metal ions in the sludge or liquid that are colored by the color developer, and convenient for visual detection.

[0060] The working process and principle of the present invention are as follows: when in use, the mounting frame 501 is put into the wastewater where heavy metal ions need to be collected. By setting the first counterweight 5013 and the second counterweight 502, the mounting frame 501 will fall to the bottom of the wastewater pool after being put into the wastewater pool. By setting the first metal screen 5011, water can pass through the first metal screen 5011 during the falling process of the mounting frame 501, avoiding affecting the falling of the mounting frame 501. By setting the second servo motor 5024, the spiral blade 5022 can be driven to rotate. The rotation of the spiral blade 5022 can stir and float the silt within the range of the mounting frame 501, making the extraction more efficient. Conveniently, by setting a second metal screen 5012, the silt outside the range of the mounting frame 501 can be prevented from entering the interior of the mounting frame 501, and then the high-pressure air pump 101 is operated to extract air, so that the silt and liquid wastewater inside the mounting frame 501 are sucked into the collection material conveying chamber 5031 through the feed port 503, and then conveyed to the through groove 601 through the collection material conveying chamber 5031, and finally flow into the circulation groove 102. By setting a hydrophobic breathable membrane 1021, firstly, the collection flow can be prevented from flowing into the high-pressure air pump 101, and secondly, the collection materials between the various heavy metal ion collection mechanisms can be prevented from mixing, by setting a discharge pipe 402.

[0061] When the high-pressure air pump 101 is running, the developer inside the liquid storage tank 401 can be drawn into the discharge pipe 402, and then flows from the discharge port 4021 to the circulation tank 102 to mix with the collected material inside the circulation tank 102. By setting the connecting tank 103, the collected material blocked by the hydrophobic breathable membrane 1021 can fall into the connecting tank 103, and then flow from the connecting tank 103 to the conveying tank 104. By setting a one-way valve 1031 inside the connecting tank 103, the backflow of the collected material can be avoided. By setting the first servo motor 3, the spiral conveyor 301 can be driven to rotate, and the collected material inside the conveying tank 104 can be adjusted by the spiral conveyor 301. The collected material is transported, and the collected material and the color developer can be mixed during the transportation process. The filter rack 204 occupies half of the space inside the collection box 2, and the filter rack 204 is located on one side of the guide trough 105. By arranging a filter 2041 inside the filter rack 204, when the collected material in the guide trough 105 flows into the collection box 2, the sludge in the collected material will remain on the top of the filter 2041, and the liquid in the collected material will flow to the bottom of the collection box 2 through the filter 2041, so that the sludge and liquid in the collected material can be stored separately, which is convenient for observing the heavy metal ions in the sludge or liquid that are colored by the color developer, and convenient for visual detection.
