Description

Technical Field

[0001] This utility model relates to the technical field of coolant recovery and purification components, and in particular to a machine tool built-in coolant recovery and purification component. Background Technology

[0002] In the field of metal processing, CNC machine tools, as high-precision and high-efficiency machining equipment, have become core equipment in the machinery manufacturing industry. Taking CNC lathes, commonly used for machining shaft and disc-shaped parts, as an example, they mainly consist of a bed, spindle box, tool post, feed transmission system, and cooling system. Among these, the cooling system plays a crucial role in the machining process. It cools and lubricates the tool and workpiece by spraying coolant onto the cutting area, while also flushing away the chips generated during machining to prevent them from scratching the workpiece surface, thus ensuring machining accuracy and tool life. However, the current use of coolant in CNC lathes and other types of machine tools generally suffers from problems such as low recycling efficiency and incomplete purification.

[0003] Traditional coolant recovery methods are often quite simple, typically involving an open collection tray at the bottom of the machine tool to collect used coolant. This method lacks an effective filtration system, resulting in the coolant containing a large amount of metal shavings, abrasive particles, and oil. Directly recycling this impurity-laden coolant not only affects cooling and lubrication, leading to increased tool wear and reduced workpiece machining accuracy, but can also cause cooling system malfunctions due to blockages in the cooling pipes, increasing equipment maintenance costs. Meanwhile, during the recycling process, the temperature of the used coolant is often high due to the lack of effective heat dissipation measures. If the high-temperature coolant is directly reused, it will reduce cooling efficiency and fail to meet the cooling requirements of the cutting area, thus affecting the machining quality.

A fine filter screen 5 is installed below the vortex assembly 4, and a collection box 6 is installed at the lower end of the receiving shell 3. The collection box 6 is sealed and fixedly connected to the receiving shell 3. The inclined collection tank 1 located below both sides of the machine tool's machining table can effectively collect the used coolant, and the inclined angle allows the coolant to flow naturally, reducing power consumption. The detachable connection between the multiple rows of filter frames 2 and the collection tank 1 facilitates cleaning and replacement of the filter frames, ensuring the filtration effect, and thus achieving the purpose of filtering the coolant layer by layer during the collection process. The swirling assembly 4 in the receiving shell 3 extends the flow length of the coolant, allowing it to fully contact the air during flow, thus increasing the cooling effect. It also increases the speed at which the coolant exits the receiving shell 3, improving recovery efficiency. The fine filter assembly 5 further refines the coolant, removing minute impurities. The collection box 6 collects the purified coolant and is sealed and fixedly connected to the receiving shell 3 to prevent coolant leakage.

[0022] Reference Figure 1 and Figure 2 As shown, the collection tank 1 includes a right-angled inclined shell 11 and a heat dissipation outer plate 12.

The flow guide shell 32 is installed at the head of the main pipe shell 31 and is fixedly connected to the main pipe shell 31. The flow guide shell 32 of the receiving shell 3, mates with the collecting tank 1, allowing coolant to be smoothly introduced into the main pipe shell 31, reducing the flow resistance of the coolant. The fixed connection between the flow guide shell 32 and the main pipe shell 31 ensures the overall structural stability of the receiving shell 3, allowing the coolant to smoothly enter the receiving shell 3 for subsequent processing. Both the main pipe shell 31 and the flow guide shell 32 are made of 304 stainless steel and are welded together.

[0025] Reference Figure 2 and Figure 5 As shown, the vortex assembly 4 includes a spiral plate 41 and an inner baffle 42.

The spiral plate 41 and the inner baffle 42 of the vortex assembly 4 cooperate to form a spiral flow of coolant within the main pipe housing 31, extending the flow path of the coolant and increasing the contact time between the coolant and air, thereby improving the cooling effect. At the same time, the spiral flow also allows the coolant to separate some impurities under the action of centrifugal force, improving the purification effect. In addition, the spiral flow can also increase the speed at which the coolant is discharged from the receiving housing 3, facilitating better filtration below. The spiral plate 41 is made of 3mm thick 304 stainless steel plate, and the inner baffle 42 is made of 2mm thick 304 stainless steel plate, and they are welded together.

The top pressure ring 51 is made of ABS engineering plastic, and the filter housing 52 is made of high-density polyethylene (HDPE) material, with an activated carbon filter element inside to further adsorb oil and odors in the coolant.

[0027] Reference Figure 1 and Figure 2 As shown, a connecting pipe 61 is fixedly installed on the upper end face of the collection tank 6, and a sleeve 311 is provided on the lower end face of the main pipe shell 31 to seal and connect with the connecting pipe 61. The sleeve 311 and the main pipe shell 31 are integrally formed. The sealing connection between the connecting pipe 61 on the upper end face of the collection tank 6 and the sleeve 311 on the lower end face of the main pipe shell 31 ensures the sealing between the collection tank 6 and the receiving shell 3, preventing coolant leakage. The integral formation of the sleeve 311 and the main pipe shell 31 enhances the stability of the structure, allowing the coolant to safely flow into the collection tank 6 for collection. The connecting pipe 61 is made of PVC plastic pipe, and the sleeve 311 and the main pipe shell 31 are welded together to ensure sealing. A liquid level sensor, model PT100, is installed at the bottom of the collection tank 6 to monitor the coolant level. When the liquid level reaches the set value, the drain pump is automatically started to transport the purified coolant back to the coolant tank. The drain pump is a small submersible pump, model QDX1.5-17-0.75, with a power of 0.75kW.

[0028] Working principle: The coolant generated during machine tool processing first flows into the inclined collection tank 1, where it undergoes preliminary filtration through multi-row filter frames 2, intercepting larger metal chips and impurities. The pre-filtered coolant flows into the receiving shell 3, where it forms a vortex under the action of the vortex assembly 4, extending the flow path, lowering the temperature, and using centrifugal force to separate some impurities. Then, the coolant undergoes fine filtration through the fine filter screen assembly 5, removing minute impurities and oil stains. Finally, the purified coolant flows into the collection tank 6. When the liquid level reaches a set value, the liquid level sensor PT100 activates the drain pump QDX1.5-17-0.75, transporting the coolant back to the coolant tank, thus achieving coolant recovery and recycling.

[0029] Other implementation methods: In other embodiments, the shape of the heat dissipation fins 121 can be adjusted according to actual needs, for example, using a corrugated or needle-like structure to improve heat dissipation efficiency. The material of the inner filter plate 22 can also be selected from other materials with good filtration performance, such as ceramic filter elements or polymer membranes. The structure of the swirl assembly 4 can also be improved, for example, by adding guide vanes or changing the tilt angle of the spiral plate to optimize the swirl effect. The filter element of the fine filter group 5 can be selected according to the type of coolant and the characteristics of impurities, for example, using activated carbon filter elements, diatomaceous earth filter elements, or ultrafiltration membranes. The material of the collection box 6 can also be selected from other materials with good corrosion resistance, such as fiberglass or polypropylene.

Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
