Description

Technical Field

[0001] This utility model relates to the technical field of quenching fluid treatment equipment, and in particular to a composite quenching fluid waste recovery and treatment device. Background Technology

[0002] Quenching fluid is a liquid used in metal heat treatment processes to rapidly cool heat-treated metal workpieces. It is commonly used in quenching processes, which involve heating metal to a certain temperature and then rapidly immersing it in a cooling medium to quickly cool the metal, thereby altering its internal structure and properties, and increasing its hardness and strength. Waste liquid recycling and treatment equipment is specifically designed to collect, treat, and recycle waste liquids generated in industrial production. Waste liquids typically refer to liquids generated during industrial production that contain pollutants and are no longer suitable for continued use, such as quenching fluids, chemical waste liquids, and oily wastewater. The main purpose of waste liquid recycling and treatment equipment is to remove harmful components from waste liquids through physical, chemical, and biological treatment methods, reducing environmental pollution while simultaneously recovering resources and achieving waste liquid reuse.

[0003] Existing quenching fluid waste recovery devices mainly consist of a filtration system, a separation system, a storage system, a pumping system, and a control system. The working principle involves the filtration system removing impurities from the waste fluid, the separation system separating contaminants such as grease and metal shavings, the storage system storing the clean recovered fluid, the pumping system returning the clean fluid to the quenching process for reuse, and the control system monitoring the entire recovery process to ensure stable and efficient equipment operation. Through this series of processes, quenching fluid can be effectively recovered and reused, reducing resource waste and environmental pollution.

[0004] However, in actual use, some devices do not combine physical and chemical methods for dual cleaning treatment, resulting in low waste liquid treatment efficiency. Even after the waste liquid is recycled, there are still certain pollutants, which cannot meet the dual requirements of environmental protection and production. In order to address the above problems, a composite quenching liquid waste liquid recycling and treatment device is proposed. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a composite quenching fluid waste recovery and treatment device, comprising an operating base plate 1, which is a rectangular flat plate serving as a support platform for the entire device and providing a stable foundation for the installation of other components. A filter cleaning box 2 is fixedly connected to the top of the operating base plate 1. The filter cleaning box 2 is a cuboid-shaped box that effectively resists corrosion from the quenching fluid waste and extends the service life of the box. A processing mechanism is fixedly connected inside the filter cleaning box 2. The processing mechanism includes a perforated annular plate 3 with evenly distributed small circular holes on its surface, allowing the waste fluid to flow out smoothly while effectively filtering out larger impurities. The bottom of the perforated annular plate 3 is fixedly connected to the lower inner end of the operating base plate 1, and the top of the perforated annular plate 3 is fixed... A connecting load-bearing plate 4 is connected, which is a square metal plate. A storage box 8 is detachably connected inside the connecting load-bearing plate 4. The storage box 8 is a rectangular plastic box with good corrosion resistance and is used to temporarily store the pre-filtered waste liquid. A drive assembly is fixedly connected to the top of the connecting load-bearing plate 4. The drive assembly includes a motor 5. The bottom of the motor 5 is fixedly connected to the top of the connecting load-bearing plate 4. A rotating connecting shaft 6 is fixedly connected to the drive end. The rotating connecting shaft 6 is a cylindrical metal shaft. Under the drive of the motor 5, the rotating connecting shaft 6 can rotate at high speed around its own axis. The outside of the rotating connecting shaft 6 is fixedly connected to the outside of multiple mixing plates 7. The outside of the mixing plates 7 is slidably connected to the inside of the annular perforated plate 3.

[0034] The drive assembly is fixedly connected to multiple mixing plates 7, which are rectangular in shape. Through stirring, they enable impurities in the waste liquid to settle and separate more effectively. A cleaning component is slidably connected inside the load-bearing plate 4. The cleaning component includes a sliding connecting block 9, which is square in shape. Its width matches the width of the bottom of the sliding connecting block 9 to ensure smooth sliding. The bottom of the sliding connecting block 9 is slidably connected to the internal groove of the load-bearing plate 4. Cleaning brush plates 10 are fixedly connected to both the left and right ends of the bottom of the sliding connecting block 9. The cleaning brush plate 10 is a rectangular plate structure. Two cleaning brush plates 10 are respectively attached to the inner and outer sides of the annular perforated plate 3. When the sliding connecting block 9 slides in the groove, the cleaning brush plate 10 can clean the surface of the annular perforated plate 3 and prevent the holes from being blocked by impurities. The side of the two cleaning brush plates 10 that is close to each other, that is, the side that is away from the two cleaning brush plates 10, is fixedly connected to the inner and outer sides of the annular perforated plate 3. The surface of the annular perforated plate 3 has small circular holes, which facilitates the outflow of waste liquid and filters the impurities in the waste liquid.

[0035] Reference Figure 1 , Figure 2 and Figure 4 The top of the operating base plate 1 is fixedly connected to a water-oil separation tank 11, which is also a rectangular box. A separation mechanism is fixedly connected inside the water-oil separation tank 11. The separation mechanism includes a water inlet pipe 12, which is cylindrical and used to introduce the pre-filtered waste liquid into the water-oil separation tank 11. The outside of the water inlet pipe 12 is fixedly connected to the inside of the water-oil separation tank 11. A low plate baffle plate 13 is fixedly connected inside the water-oil separation tank 11, with a circular hole at the bottom. A high plate baffle plate 14 is fixedly connected inside the water-oil separation tank 11, with a circular hole at the bottom. Its function is to change the flow path of the waste liquid in the water-oil separation tank 11, prolong the residence time of the waste liquid, and promote the separation of water and oil. A high square baffle plate 15 is fixedly connected inside the water-oil separation tank 11. The high square baffle plate 15 is a square plate, which further enhances the water-oil separation effect.

[0036] The water-oil separator 11 is internally fixedly connected to a discharge assembly, which includes an oil discharge pipe 16. The oil discharge pipe 16 is cylindrical and is used to discharge the separated oil. The outside of the oil discharge pipe 16 is fixedly connected to the inside of the water-oil separator 11. The inside of the water-oil separator 11 is also fixedly connected to a liquid discharge pipe 17, which is also cylindrical. The outside of the liquid discharge pipe 17 is fixedly connected to a transport connection pipe 18, which is used to transport the separated liquid to the connecting load-bearing plate 4 for further processing. The other end of the transport connection pipe 18 is fixedly connected to the inside of the connecting load-bearing plate 4.

[0037] Working principle: First, the waste liquid to be recycled is transported to the interior of the water-oil separator 11 through the inlet pipe 12. Under the obstruction of the low plate baffle 13, the waste liquid slowly enters the middle area of ​​the water-oil separator 11 through the holes at the bottom of the low plate baffle 13. Due to the different densities of water and oil in the waste liquid, the oil, which has a lower density, floats upward. After entering the middle of the water-oil separator 11, most of the oil in the waste liquid is at the top of the water-oil separator 11, while the water in the waste liquid is at the bottom of the water-oil separator 11. Then, through the holes in the high plate baffle 14, the water in the waste liquid continues to flow to the rear of the water-oil separator 11, while the oil in the waste liquid flows from the top. Finally, the oil in the waste liquid is blocked by the high square baffle plate 15 and cannot flow backward, so it is discharged through the oil outlet pipe 16. The water in the waste liquid flows through the gap between the high square baffle plate 15 and the water-oil separator 11 to the liquid outlet pipe 17 and is discharged. It is then transported to the next process through the transport connection pipe 18.

[0038] After the water-oil separation process, the waste liquid enters the interior of the annular perforated plate 3. Because the connecting load-bearing plate 4 at the top of the annular perforated plate 3 is equipped with a storage tank 8, chemicals are placed inside the storage tank 8 to clean the waste liquid. Simultaneously, the motor 5 is started, driving the rotating connecting shaft 6 to rotate. Driven by the rotating connecting shaft 6, multiple external stirring and mixing plates 7 rotate inside the annular perforated plate 3, ensuring thorough mixing of the waste liquid and chemicals, thus treating the waste liquid. The numerous tiny holes on the surface of the annular perforated plate 3 facilitate the mixing of the waste liquid with the chemicals. Waste liquid inside the annular perforated plate 3 flows outward through the holes, thereby filtering out impurities mixed in the waste liquid and further cleaning the waste liquid. It then flows into the filter cleaning box 2 and is transported outward through the pipeline. During long-term use, a large amount of garbage remains in the holes on the surface of the annular perforated plate 3. Holding the sliding connecting block 9 and sliding it in the groove inside the connecting load-bearing plate 4 causes the cleaning brush plate 10 connected to the sliding connecting block 9 to slide on both the inner and outer sides of the annular perforated plate 3, thereby cleaning the garbage on the annular perforated plate 3.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
