Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a device for separating metal substances in wastewater. Background Art

[0002] At present, many production processes in industries such as mining, metallurgy, and machinery manufacturing will produce wastewater containing heavy metals. These wastewaters containing heavy metals cannot be discharged directly and need to be treated. They can only be discharged after meeting the standards. When treating wastewater containing heavy metals, it is first necessary to separate the solid impurities it contains from the wastewater, especially the metal substances it contains can be recycled. The existing wastewater separation device generally filters the wastewater first, filters out the impurities in the wastewater, and then proceeds to the next step of purification.

[0003] For example, the public document with application number 202322449801.3 discloses a heavy metal wastewater separation device. The utility model cooperates with two transmission rollers and a transmission belt, and the filter holes arranged in an array on the transmission belt not only serve as a filter for wastewater, but also as a transmission member for transmitting intercepted impurities, so that when filtering the wastewater, the intercepted impurities can be discharged in real time, so that they will not be blocked, ensuring the smoothness of the filtration. The device as a whole does not need to be stopped to clean up the impurities at the same time, and subsequently through the cooperation of the sleeve, the magnetic ring and the first scraper, the metal substances and non-metallic substances in the impurities can be separated, which is convenient for the recycling of the metal substances, thereby improving the practicality. However, the device has a large overall volume. After the wastewater is discharged, it needs to be collected first and then transferred to the inside of the equipment for treatment for the second time, which increases the treatment process and is inconvenient to use. The production cost of the device is also high, which is not conducive to large-scale purchase and use. The filter inside the device is also not easy to replace. The filter will age, rub and break due to long-term use, which affects the filtration effect and leads to a decrease in filtration quality.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a device for separating metal substances in wastewater is proposed. Utility Model Content

[0015] 3. The utility model arranges the filter box, the water inlet connector, the drain connector and the rubber sealing gasket, and the filter box centrally assembles the filter components, so that the whole device is smaller in size and has lower manufacturing costs. The water inlet connector and the drain connector can be directly assembled in the middle section of any pipe for use, making the device more convenient to use, and having better practicality and ease of use. The rubber sealing gasket can fit tightly with the edge of the through cavity when the baffle is assembled, and the assembly frame can fit tightly with the baffle and the inner surface of the filter box, effectively avoiding leakage of wastewater without being filtered, improving the assembly sealing, and making the wastewater filtration more stable.

[0027] By adopting the above technical solution, the latch 402 can be inserted into the positioning groove 6 to lock, and can be moved out of the positioning groove 6 to unlock.

[0028] Furthermore, the locking member 4 also includes a spring 403 fixedly mounted on the surface of the latch 402 , a side of the latch 402 close to the baffle 3 is arranged as an inclined surface, and one end of the spring 403 is fixedly connected to the fixing block 401 .

[0029] By adopting the above technical solution, the inclined surface enables the docking block 5 to directly push the latch 402 to slide and retract, and during installation, there is no need to manually pull the latch 402;

[0030] The spring 403 provides a driving force for the latch 402. When the latch 402 is flush with the positioning groove 6, the elastic force of the spring 403 will automatically insert the latch 402 into the positioning groove 6 and lock it.

[0031] like Figure 2 and Figure 4 As shown, three slots 9 are evenly distributed on the left side of the surface of the baffle 3 , and insert blocks 10 are slidably inserted inside the slots 9 .

[0032] By adopting the above technical solution, the slot 9 and the plug block 10 are slidably plugged, so that the filter screen 13, the filter cotton 14 and the activated carbon 15 on the left side of the baffle 3 can be removed and replaced separately.

[0033] Furthermore, an assembly frame 11 is fixedly installed on the left end of the insert block 10 , and rubber sealing pads 12 are fixedly arranged around the outer sides of the assembly frame 11 and the baffle 3 .

During insertion, the docking block 5 uses the inclined surface to push the latch 402 to extend outward, and pulls the spring 403 to extend. When the latch 402 is flush with the positioning groove 6, Under the elastic force of spring 403, latch 402 will be reset and inserted into positioning groove 6, thereby fixing baffle 3, that is, fixing the entire filter element and filter box 1, and the wastewater is filtered layer by layer through filter screen 13, filter cotton 14 and activated carbon 15, and the filtered metal substances will remain in the frame formed by assembly frame 11 and filter element and collect. After long-term use, pull latch 402 out of positioning groove 6, baffle 3 can be removed from through cavity 2, and then the filter assembly can be disassembled and replaced as a whole, and the filter element can be slidably plugged into slot 9 and plug block 10, so that filter screen 13, filter cotton 14 and activated carbon 15 can be removed and replaced separately, and the above-mentioned "filter element / filter assembly" is composed of assembly frame 11 and each fixedly assembled filter screen 13, filter cotton 14, activated carbon 15, which is the working principle of the metal substance separation device in wastewater.
