Description

Technical Field

[0001] This utility model relates to the field of machining, specifically a cutting fluid circulation filtration device. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal processing to cool and lubricate cutting tools and workpieces. It is usually formulated with base oil and additives, and can effectively reduce cutting temperature, reduce friction and wear, and at the same time play a role in rust prevention and cleaning of machining debris. It is widely used in turning, milling, grinding and other machining scenarios, and can improve machining accuracy, extend tool life and improve the working environment.

[0003] The use of cutting fluid usually begins with preparation, where the concentrate is mixed and diluted with water according to the specified ratio. It is then continuously delivered to the cutting area through pipes or nozzles, acting directly on the contact point between the tool and the workpiece to provide cooling and lubrication. During use, it is necessary to regularly check indicators such as concentration and replenish and adjust accordingly, while removing impurities through a filtration device. When the cutting fluid deteriorates, the old fluid must be drained, the system cleaned, and replaced with new fluid to ensure machining results.

[0004] Existing cutting fluid circulation filtration devices suffer from filter screen clogging due to debris in the cutting fluid after prolonged filtration, resulting in reduced circulation filtration efficiency. Therefore, a cutting fluid circulation filtration device is proposed to address this issue. Utility Model Content

[0022] 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 scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5As shown in the embodiment of this utility model, a cutting fluid circulation filtration device includes a circulation tank 1; an inlet 11 is fixedly connected to the top of the circulation tank 1; multiple sets of filter plates 12 are fixedly connected to the inner side wall of the circulation tank 1; the filter plates 12 are arranged in an array on the inner side wall of the circulation tank 1; multiple sets of linear motors 13 are fixedly connected to the side wall of the circulation tank 1; the linear motors 13 are located at the bottom of the filter plates 12; a first support rod 14 is slidably connected to the side wall of the linear motor 13; a water pipe 15 is fixedly connected to the side wall of the first support rod 14; a push plate 16 is slidably connected to the side wall of the circulation tank 1; the... A pusher plate 16 is positioned at the top of the filter plate 12; the filter plate 12 is slidably connected to the pusher plate 16; a push rod 17 is slidably connected to the side wall of the pusher plate 16; an outlet 18 is provided at the bottom of the circulation tank 1; during operation, used cutting fluid is added into the inlet 11, and the cutting fluid comes into contact with multiple sets of filter plates 12. The filter pore sizes of the filter plates 12 are different, so that the debris inside the cutting fluid is filtered through multiple layers of filter plates 12. The cutting fluid filtered by the filter plates 12 can flow out from the outlet 18. Connecting the outlet 18 to the machining platform can realize circulation filtration. After filtration, a significant amount of debris will accumulate on the surface. At this point, multiple water pipes 15 can be connected to the spraying liquid, and the water pump can be started. The spraying liquid will then be ejected from the nozzle at the top of the first support rod 14. The linear motor 13 is activated to move the first support rod 14, which can reverse-wash the debris accumulated on the filter plate 12, causing the debris on the surface of the filter plate 12 to be blown away. Pushing the push rod 17 then moves multiple push plates 16, which can push the debris on the surface of the filter plate 12 to one end of the filter plate 12, thus cleaning the debris from the surface of the filter plate 12. This process is achieved by arranging multiple filter plates 12 in an array... Different filter pore sizes allow for multi-layer filtration of the cutting fluid, increasing its cleanliness after circulation and reducing wear on processing equipment and workpieces during recycling. The sprayed fluid connected through water pipe 15 backwashes the filter plate 12, and the push rod 17 drives the push plate 16 to push away debris, effectively removing debris accumulated on the surface of the filter plate 12, reducing the decrease in filtration efficiency caused by surface clogging, and further increasing the effect of circulation filtration, making the circulation continuous. The backwashing of water pipe 15 can also more thoroughly remove debris from the surface of the filter plate 12, further increasing the cleaning effect of the push plate 16.

[0025] like Figures 1 to 3As shown, a groove 2 is provided at the top of the filter plate 12; the groove 2 is correspondingly arranged with the filter plate 12; a collection net 21 is fixedly connected to the bottom of the groove 2; a sealing door 22 is slidably connected to the side wall of the circulation box 1; during operation, the debris pushed by the push plate 16 can fall into the groove 2 and then be collected by the collection net 21. After the collection net 21 has collected a large amount of debris, a pulling force can be applied to the sealing door 22, and then the side of the circulation box 1 can be opened, and then the collection net 21 can be replaced; the debris pushed by the push plate 16 falls into the groove 2 and is collected by the collection net 21, which can reduce the backflow of debris on the surface of the filter plate 12 with the cutting fluid, further increasing the cleaning effect of the surface of the filter plate 12, keeping the surface of the filter plate 12 clean. Pulling the sealing door 22 to remove the collection net 21 allows for quick replacement of the collection net 21 and further recycling of debris.

[0026] like Figure 1 and Figure 4 As shown, a pair of second support rods 3 are fixedly connected to the top of the circulation tank 1; an inclined plate 31 is fixedly connected to the top of the second support rods 3; the inclined plate 31 is located on one side of the feed inlet 11; a plurality of magnetic blocks 32 are arranged in an array on the top of the inclined plate 31; during operation, when the cutting fluid is added from the feed inlet 11, the cutting fluid can also be poured onto the surface of the inclined plate 31. The inclined setting of the inclined plate 31 will guide the cutting fluid to flow to the feed inlet 11. When the cutting fluid flows on the top of the inclined plate 31, the magnetic blocks 32 can adsorb the iron filings mixed in the cutting fluid; the magnetic blocks 32 can pre-adsorb the iron filings in the cutting fluid before it enters the feed inlet 11, intercept some contaminants in advance, reduce the filtration time of the subsequent filter plate 12, and extend the effective filtration time of the filter plate 12.

[0027] like Figure 4 As shown, a guide plate 4 is fixed to the inner wall of the circulation tank 1; the guide plate 4 is located below the feed inlet 11; a groove 41 is formed on the side wall of the guide plate 4; during operation, when the cutting fluid falls from the feed inlet 11, it can contact the guide plate 4, and then the guide plate 4 guides the cutting fluid to flow out from the groove 41, so that the cutting fluid is evenly distributed when it flows to the surface of the filter plate 12; by diverting and guiding the cutting fluid through the groove 41, the cutting fluid is evenly distributed to various areas of the surface of the filter plate 12, which can reduce the cutting fluid falling from one position of the filter plate 12 due to excessive local flow of the filter plate 12, causing local blockage of the filter plate 12, and improving the overall filtration speed and effect.

[0028] like Figure 3As shown, a scraper 5 is fixedly connected to the side wall of the push plate 16; the scraper 5 is slidably connected to the filter plate 12; during operation, when the push plate 16 moves to push the debris on the surface of the filter plate 12, the scraper 5 can also contact the filter plate 12 to further scrape up the debris on the surface of the filter plate 12; by scraping up the tightly attached debris on the surface of the filter plate 12 on the basis of the push plate 16 pushing the debris, the effect of the push plate 16 can be increased.

[0029] like Figure 5 As shown, a sealing ring 6 is fixed to the side wall of the circulation tank 1; the sealing ring 6 is correspondingly arranged with the water pipe 15; during operation, when the linear motor 13 drives the first support rod 14 to move, the water pipe 15 will slide on the side wall of the circulation tank 1, and the sealing ring 6 can seal the water pipe 15 when it slides, so that the cutting fluid is blocked inside the circulation tank 1; by forming a seal when the water pipe 15 slides, the cutting fluid inside the circulation tank 1 can be effectively reduced from seeping out from the sliding gap between the water pipe 15 and the side wall of the circulation tank 1, thus reducing the waste of cutting fluid.

[0030] Working principle: Used cutting fluid is added into the inlet 11. The cutting fluid comes into contact with multiple sets of filter plates 12. The filter plates 12 have different pore sizes, allowing the cutting fluid debris to be filtered through multiple layers of filter plates 12. The cutting fluid filtered by the filter plates 12 can flow out from the outlet 18. Connecting the outlet 18 to the machining platform enables circulation filtration. After prolonged filtration by the filter plates 12, a large amount of debris will accumulate on the surface. At this time, multiple sets of water pipes 15 can be connected to the spraying liquid, and then the water pump can be started to spray... The spray is emitted from the nozzle at the top of the first support rod 14. Activating the linear motor 13 moves the first support rod 14, which reverses the flow of debris accumulated on the filter plate 12, blowing away the debris. Pushing the push rod 17 then moves multiple sets of push plates 16, which push the debris on the surface of the filter plate 12 to one end, thus cleaning the debris. The debris pushed by the push plates 16 falls into the trough 2 and is then collected by the collection net 21. After collecting a large amount of debris using the collection net 21, a pulling force can be applied to the sealing door 22, and then the side of the circulation tank 1 can be opened. The collection net 21 can then be replaced. When adding cutting fluid through the inlet 11, the cutting fluid can also be poured onto the surface of the inclined plate 31. The inclined plate 31 then guides the cutting fluid to flow to the inlet 11. As the cutting fluid flows at the top of the inclined plate 31, the magnetic block 32 can attract iron filings mixed in with the cutting fluid. When the cutting fluid falls from the inlet 11, it can connect with the guide plate 4. Upon contact, the guide plate 4 guides the cutting fluid to flow out from the groove 41, so that the cutting fluid is evenly distributed when it flows to the surface of the filter plate 12. When the push plate 16 moves and pushes the debris on the surface of the filter plate 12, the scraper 5 can also contact the filter plate 12 to further scrape up the debris on the surface of the filter plate 12. When the linear motor 13 drives the first support rod 14 to move, the water pipe 15 will slide on the side wall of the circulation tank 1. The sealing ring 6 can seal the water pipe 15 when it slides, so that the cutting fluid is blocked inside the circulation tank 1.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
