Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of recycling of cutting fluids in mechanical processing, in particular to a cutting fluid circulation mechanism for sprocket processing. Background Art
[0002] Sprockets are key components of coal mining machines. They are large components. During sprocket processing, the blanks generally need to be CNC milled for finishing. During milling, cutting fluid is required for cooling. If the cutting fluid cannot be recycled, it will not only cause material waste but also pollute the environment. Therefore, the cutting fluid is generally recycled. Existing cutting fluid circulation treatment mostly adopts a centralized treatment system. During centralized treatment, the pressure of the pre-treatment equipment in the front section is high, which affects the filtration quality of the filtration device in the back section, thereby affecting the impurity content in the circulating cutting fluid. Once the impurity content of the cutting fluid is improperly controlled, not only the processing quality is greatly affected, but the cutting fluid will also quickly deteriorate. Frequent fluid changes will cause a significant increase in production costs and will also cause rust in the processing equipment in the long term. Utility Model Content
[0003] In order to solve the above problems, the utility model provides a sprocket machining cutting fluid circulation mechanism.
[0004] The utility model is realized as follows: a sprocket processing cutting fluid circulation mechanism comprises a liquid receiving box, wherein the liquid receiving box is arranged under a CNC machine tool, and the cutting fluid waste generated during the sprocket processing is directly sent to the liquid receiving box through a pipeline. This process does not require a liquid pump, and depends on the height difference between the processing position of the machine tool and the liquid receiving box. The middle of the liquid receiving box is provided with a preliminary filter screen, and the upper part is provided with a magnetic plate cover. Before the recovered liquid enters the paper belt filter, each CNC machine tool will first filter the recovered liquid generated by each of the respective CNC machine tools, adopt a distributed design, reduce the filtering pressure of the paper belt filter, and do not need to set a pre-treatment device before the paper belt filter. During actual operation, each machine tool has an operator to regularly clean the impurities on the preliminary filter screen in the liquid receiving box, and the magnetic plate cover on the upper part of the liquid receiving box can absorb and remove metal debris in the cutting fluid. The liquid receiving box is connected to the collection ditch, and one end of the liquid receiving box extends above the collection ditch. The bottom of the liquid receiving box A pipeline is set in the part, which is inserted into the collection ditch. The recovered liquid of the liquid receiving box is discharged into the collection ditch. The collection ditch is connected to the liquid accumulation pool. The recovered liquid flows into the liquid accumulation pool in the collection ditch. An oil-water separator is set above the liquid accumulation pool. The recovered liquid is layered in the oil-water separator to remove the floating oil on the upper layer. The oil-water separator is provided with a floating oil discharge port. The oil-water separator is also provided with a pipeline connected to the paper belt filter. A collecting box is set at the bottom of the paper belt filter. The collecting box is connected to the liquid distribution box. The pH value and concentration of the recovered liquid need to be adjusted when it is recycled for production after regeneration. During the recycling process, the recovered liquid will also have microbial bacteria and mold breeding. A pH regulating liquid pipe, a raw liquid pipe and a tap water pipe are set above the liquid distribution box. The liquid distribution box is also connected to an ozone generator for adjusting the pH value, concentration and sterilization. The liquid distribution box is connected to the CNC machine tool cutting fluid supply system.
[0005] The paper belt filter includes a filter paper stick, filter paper, a liquid separator, a surrounding edge, a floating plate, a drag chain, a transmission stick and a slag box. The working principle of the paper belt filter is as follows: the recovered liquid from the bottom of the oil-water separator is transported to the liquid separator under the action of a liquid pump. The liquid separator is arranged above the surrounding edge. A drag chain is arranged at the bottom of the surrounding edge. The drag chain circulates under the action of the transmission stick. The transmission stick on one side is connected to the motor output shaft. Filter paper is also laid above the surrounding edge and the drag chain. The filter paper comes from the filter paper stick on one side of the surrounding edge. A slag box is arranged on one side of the filter paper stick below the drag chain. A floating plate is arranged above the filter paper. The recovered liquid flows to the filter paper through the liquid separator. The recovered liquid filtered by the filter paper flows into the collection box after removing fine impurities and grease. After the filter paper is gradually covered with filter residue, the filtration rate slows down, the liquid level rises, and the float rises with the liquid level. When the transmission rod motor switch is triggered, the transmission rod motor starts, drives the drag chain to rotate, moves the filter paper forward, releases a small amount of new filter paper, increases the filtration rate, and the recovered liquid level drops. The transmission rod motor is powered off, the drag chain and filter paper stop moving, and filtration continues. The filter paper with filter residue is transported to the residue receiving box. This cycle of action realizes the filtration function of the paper belt filter.
[0006] The liquid distribution box is also provided with a stirring mechanism, which includes a stirring blade and a stirring motor. When tap water, raw liquid or pH regulating liquid enters the liquid distribution box, the stirring motor is started and the stirring blade rotates in the liquid distribution box to mix the liquid evenly.
[0007] A comprehensive pH and temperature detection box is also provided in the liquid distribution box. The values of the detection box are displayed outside the liquid distribution box, making it convenient to observe the pH value and temperature of the liquid in the liquid distribution box.
[0008] The liquid receiving box is arranged above the collecting ditch, so that the liquid distribution box can flow from the liquid receiving box to the collecting ditch under the action of gravity.
[0009] The beneficial effects of the present utility model are: 1. A distributed structure is used to arrange the liquid collecting box to collect the cutting fluid generated by the CNC machine tools for sprocket processing, and perform preliminary filtration and remove impurities such as iron filings in the recovered liquid, thereby reducing the pre-treatment pressure of the paper bag filter. 2. Utilizing the existing pipe trench system in the processing workshop, the recovered liquid flows into the liquid accumulation pool under the action of gravity, saving power usage. 3. A paper belt filter is used for fine filtration, and the recovered liquid has less impurity content after filtration, meeting the recycling requirements. 4. The liquid distribution box is provided with a pH regulating liquid pipe and an ozone delivery pipe, which is convenient for controlling the pH value of the circulating liquid and preventing the growth of microorganisms. The utility model has a reasonable design, can ensure the quality requirements of sprocket processing and cutting recycling, reduces the amount of cutting fluid used, reduces the raw material consumption cost of sprocket processing, and improves the economic benefits of the enterprise.

A primary filter screen 201 is provided in the middle of the liquid receiving box 2, and a magnetic plate cover 202 is provided on the upper part. The liquid receiving box 2 is connected to the collection ditch 3, and the collection ditch 3 is connected to the liquid accumulation pool 4. An oil-water separator 5 is provided above the liquid accumulation pool 4. The oil-water separator 14 is used to separate floating oil in the cutting fluid. The oil-water separator 5 is provided with a floating oil discharge port 501. The oil-water separator 5 is also provided with a pipeline connected to the paper belt filter 6. The paper belt filter 6 includes a filter paper stick 601, filter paper 602, a liquid separator 603, a surrounding edge 604, a floating plate 605, a drag chain 606, a transmission stick 607 and a slag box 608. The filter paper roll 601 is used to store clean filter paper. The filter paper 602 is used to filter fine impurities from the recovered cutting fluid. The liquid separator 603 is used to disperse the recovered fluid from the oil-water separator onto the surface of the filter paper. The edge 604 cushions the edge of the filter paper to facilitate the storage of the recovered fluid. The float 605 is linked to the motor mechanism of the drive roller 607. When the level of the recovered fluid on the filter paper rises with the float 605, the drive roller 607 is activated, driving the drag chain 606 to rotate, thereby moving the filter paper 602 forward and removing new filter paper from the filter paper roll 601. The bottom of the paper belt filter 6 is provided with a collection box 7. The collection box 7 is connected to the liquid distribution box 8. Above the liquid distribution box 8 are installed a pH adjustment liquid pipe 13, a raw liquid pipe 15, and a tap water pipe 17. The liquid distribution box 8 is also connected to the ozone generator 9. The liquid distribution box 8 is connected to the CNC machine tool cutting fluid supply system, and a machine tool liquid supply pump 20 is installed on the connecting pipe. The pH regulating liquid pipe 14, the raw liquid pipe 16, and the tap water pipe 17 are respectively equipped with a pH regulating liquid pump 14, a raw liquid pump 16, and a tap water pump 18. The liquid distribution tank is equipped with a stirring mechanism 10, which includes stirring blades and a stirring motor. The liquid distribution tank is also equipped with a comprehensive pH and temperature detection box. The liquid receiving box 2 is located above the collection trench 4. The liquid distribution tank is equipped with a heating mechanism. When the temperature is below the set temperature, the heating mechanism starts heating. When the temperature reaches the set temperature, the heating mechanism stops heating.
[0016] System Working Principle: During sprocket machining, CNC machine tools use cutting fluid, which may contain impurities such as grease and metal debris carried by the machine. The cutting fluid flows into the liquid receiving tank under the action of gravity. After initial filtration and removal of metal debris in the liquid receiving tank, it flows into the collection ditch and then into the liquid accumulation tank. From the liquid accumulation tank, it is transported to the oil-water separator 5 by the liquid pump 1 401 for oil-water separation. Then, it is transported to the paper bag filter by the liquid pump 2 501. After fine filtration on the paper belt filter, the recovered liquid is collected in the collection tank. The recovered liquid in the collection tank is transported to the liquid distribution tank by the liquid pump. After pH adjustment, concentration adjustment, ozone sterilization and other processes in the liquid distribution tank, it becomes a recycled sprocket machining cutting fluid and is transported to the CNC machine tool for use. The cutting fluid circulation mechanism of this utility model is rationally designed, the cutting fluid quality is guaranteed, saving costs for enterprises while meeting the sprocket machining requirements.
