Description

Technical Field

[0001] This utility model relates to the technical field of cutting fluid production equipment, and in particular to a cutting fluid oil and sediment separation device based on the principle of physical separation. Background Technology

[0002] During metal cutting, grinding, and other machining processes, cutting fluids are prone to contamination with floating oil and solid impurities. Existing separation equipment mostly employs single filtration or static stratification methods, which have the following shortcomings:

[0003] 1. Low separation efficiency: When oil and sediment are mixed and separated, secondary pollution is easily caused by fluid disturbance, and the settling path of solid particles is short, making it difficult to completely intercept fine impurities.

[0004] 2. High maintenance costs: The filter components are mostly integrated structures, requiring the machine to be stopped and the entire chamber to be disassembled during cleaning, which is cumbersome and time-consuming.

[0005] 3. Limited functionality: It cannot simultaneously recover floating oil and classify and collect metal / non-metal impurities, resulting in low resource utilization.

[0006] Therefore, there is an urgent need for a structural device based on the principle of physical separation, which can achieve efficient preliminary separation and convenient collection of floating oil and sediment in cutting fluid by optimizing the fluid path and the functional partitioning of the chamber, thus providing a prerequisite for subsequent deep purification treatment. Utility Model Content

[0007] 1. Technical problem to be solved:

[0008] In view of the problems existing in the prior art, the purpose of this utility model is to provide a cutting fluid floating oil and sediment separation device, which can realize the physical separation and convenient collection of floating oil and sediment in cutting fluid.

[0009] 2. Technical Solution:

[0010] To solve the above problems, the present invention adopts the following technical solution.

[0011] A cutting fluid oil and sediment separation device includes a base, an operating platform at the front end of the base, and the upper surface of the operating platform is flush with the upper surface of the base.

[0012] A separation box is mounted on the base, and the top of the separation box is connected to an openable and closable lid via a hinge shaft.

[0013] The separation box has a pull-out slot on the side facing the operating platform. A sediment collection component is slidably installed in the pull-out slot. When the sediment collection component is pulled out, the extended end is located directly above the operating platform.

[0014] A further improvement is that the left side wall of the separation chamber is provided with a liquid inlet and the right side wall is provided with a liquid outlet, and the central axes of the liquid inlet and the liquid outlet are coplanar.

[0015] The separation chamber has a first drain valve at the bottom of the left side wall and a second drain valve at the bottom of the right side wall. The second drain valve is installed at a lower height than the first drain valve, and the second drain valve and the liquid outlet are collinear in the vertical direction.

[0016] A further improvement is that the separation chamber is equipped with a vertical main partition, which divides the interior of the chamber into a rear scum separation chamber and a front solid-liquid filtration chamber.

[0017] The solid-liquid filtration chamber is equipped with a vertical secondary partition, which divides the solid-liquid filtration chamber into a left filtration chamber and a right filtration chamber.

[0018] The top height of the main partition is flush with the central axis of the inlet and outlet.

[0019] A further improvement is that a first flow guide baffle is fixed to the inner wall of the left side of the separation box. The vertical section of the first flow guide baffle surrounds the liquid inlet outlet, and the horizontal section extends towards the front wall of the box to form a first buffer cavity.

[0020] The inner left wall of the separation box is also provided with an arc-shaped guide plate, which is located below the horizontal section of the first guide baffle.

[0021] A further improvement is that: an overflow hole is provided at the lower part of the sub-baffle, and the height of the overflow hole is lower than the lowest point of the arc-shaped guide plate;

[0022] A second flow guide baffle is fixed on the left side of the sub-partition plate, and its horizontal section extends to below the flow hole to form a second buffer cavity;

[0023] A stepped baffle is fixed to the right side of the sub-baffle, and the horizontal section of the stepped baffle is flush with the bottom edge of the flow hole.

[0024] A further improvement is that a third flow guide baffle is fixed to the inner wall of the right side of the separation box. Its vertical section surrounds the liquid outlet inlet, and its horizontal section extends to the front wall of the box to form a liquid outlet buffer chamber.

[0025] A further improvement is that the sediment collection assembly includes a collection box that is slidably disposed in the pull-out slot, metal filter screens are respectively embedded in the left and right side walls of the collection box, and a magnet is provided at the bottom of the collection box;

[0026] When the collection box is inserted into the separation box, its right outer wall is tightly fitted with the vertical section of the second guide baffle, and its front outer wall is sealed to the pull-out slot.

[0027] 3. Beneficial effects:

[0028] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0029] (1) Directional control of floating oil: The inlet forms a "baffle-slow flow" effect with the first guide baffle and the arc guide plate, so that the floating oil quickly rises to the liquid surface of the left filter chamber. After being blocked by the second guide baffle, it overflows through the top of the main baffle to the scum separation chamber for centralized storage, thus preventing it from entering the right filter chamber with the liquid.

[0030] The stepped baffles in the right filter chamber form a multi-stage interception interface, and residual floating oil rises step by step along the baffles.

[0031] (2) Solid impurities are graded and settled: The left filter chamber serves as the primary settling zone, where large particles of impurities settle rapidly to the bottom of the collection box under the action of gravity and the arc-shaped guide plate.

[0032] The flow passage limits the liquid to flow into the right filter chamber only from 200mm below the liquid surface, ensuring that fine particles settle further in the second buffer chamber, non-metallic impurities are intercepted by the metal filter screen, and magnetic materials such as iron filings are attracted by the magnet.

[0033] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

[0048] Please refer to the appendix. Figure 1-6 This embodiment provides a cutting fluid floating oil and sediment separation device, the main structure of which includes:

[0049] 1. The basic structure is implemented as follows:

[0050] The separation device includes a base 1 and an operating platform 2, with the platform surface flush with the upper surface of the base. The separation chamber 3 is fixed to the center of the base by flange bolts, and a hinged cover 4 is installed at its top. A pull-out slot 5 is provided on the front side of the separation chamber 3, and a sediment collection component 6 is slidably installed in the slot. When pulled out, the extended end is suspended 50mm above the operating platform 2.

[0051] Pipe and valve system: Inlet 311 and outlet 312 are respectively embedded in the left and right side walls of the tank, with the central axis 250mm from the top of the tank;

[0052] The first drain valve 313 is 100mm from the bottom of the tank, and the second drain valve 314 is 50mm from the bottom of the tank. The center lines of the two valves are coplanar with the liquid outlet 312.

[0053] 2. The chambers are divided as follows:

[0054] Inside the separation chamber 3: the main partition 31 is vertically and fully welded at a distance of 300mm from the rear wall, with its top height flush with the center of the inlet / outlet, dividing the chamber into: the rear part of the scum separation chamber 32: containing floating oil with a density of <0.85g / cm³; and the front part of the solid-liquid filtration chamber 33: settling solid impurities.

[0055] The secondary partition 34 is vertically welded to the middle of the solid-liquid filtration chamber 33, dividing it into: left filtration chamber 331: primary sedimentation zone; right filtration chamber 332: fine separation zone.

[0056] 3. The diversion system will be implemented as follows:

[0057] Liquid inlet guide assembly: The vertical section of the first guide baffle 35 is circumferentially welded around the liquid inlet 311, and the horizontal section extends forward 300mm to the front wall of the tank to form the first buffer chamber 351;

[0058] The arc-shaped guide plate 36 is welded 80mm below the first guide baffle.

[0059] Overflow control components: A liquid inlet hole 341 is provided at the lower part of the secondary baffle 34, with the bottom of the hole 200mm from the bottom of the tank;

[0060] The horizontal section of the second guide baffle 342 extends below the liquid inlet hole 341, forming a second buffer cavity 3421 with the front wall of the tank.

[0061] The stepped baffle 343 has its horizontal surface flush with the bottom edge of the liquid inlet hole 341.

[0062] Liquid outlet guide assembly: The vertical section of the third guide baffle 37 is circumferentially welded around the liquid outlet 312, and the horizontal section extends forward 300mm to form the liquid outlet buffer chamber 371.

[0063] 4. The collection unit is implemented as follows:

[0064] The sediment collection assembly 6 includes: a collection box 61 that is slidably nested in the pull-out slot 5, with its right outer wall perpendicular to the second guide baffle 342;

[0065] The metal filter 62 is a 100-mesh stainless steel filter, which is fixed to the two side walls of the collection box 61 by pressure strip bolts; a magnet block 63 with a size of 50mm×50mm×10mm is installed in the groove at the bottom of the box. Its surface is nickel-plated and the magnetic field strength is ≥1000 Gauss, which can effectively adsorb magnetic impurities such as iron filings.

[0066] 5. The operation process is as follows:

[0067] Step 1: Key Pretreatment for Initial Fluid Injection

[0068] Clean cutting fluid is injected into the separation chamber 3 until the liquid level is 50 mm above the bottom edge of the inlet hole 341, forming a liquid level barrier. This height design can be used to ensure that floating oil is effectively blocked by the second guide baffle 342 through fluid dynamics calculations, preventing it from entering the right filter chamber 332 with the liquid.

[0069] Step 2: Oil-solid separation operation

[0070] Liquid inlet diversion: The cutting fluid to be treated is injected into the first buffer chamber 351 from the inlet 311, and after being deflected by the first guide baffle 35, it impacts the arc-shaped guide plate 36, accelerating the oil-water separation.

[0071] Oil Floating Lock: The oil floats to the surface of the liquid and is blocked by the second guide baffle 342 outside the left filter chamber 331. The clean liquid flows through the second buffer chamber 3421 and enters the right filter chamber 332 through the liquid inlet 341.

[0072] Impurity capture: Solid particles settle into collection box 61, non-metallic objects are intercepted by filter screen 62, and iron filings are attracted by magnet block 63;

[0073] Some of the remaining floating oil or oily matter is blocked by the stepped baffle 343 and floats to the surface again in the right filter chamber 332.

[0074] Liquid output: Liquid flows from the bottom of the third guide baffle 37 into the liquid outlet buffer chamber 371 and is discharged from the liquid outlet 312.

[0075] Step 3: Impurity Cleaning Procedure

[0076] Oil spill recovery: a. As the oil spill accumulates, due to the high level limit, excess oil and scum flow into the scum separation chamber 32, ensuring that only a single layer of oil remains on the surface of the liquid; b. When cleaning is required later, the layer of oil at the top of the chamber is manually skimmed off, and the floating matter on the liquid surface is scraped into the scum separation chamber 32.

[0077] Sediment treatment: Open the second drain valve 314 to drain the residual liquid; pull the collection box 61 to the operating platform 2, remove the impurities from the filter screen 62, and disassemble the magnet block 63 to recover the metal shavings;

[0078] System maintenance: Finally, rinse the box with clean water.

[0079] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
