Description

Technical Field

[0001] The utility model relates to the technical field of iron chip separation, in particular to a high-compatibility fixed iron chip oil-water separator. Background Art

[0002] During the processing and forming of workpieces (such as screws, bolts, etc.), it is inevitable that some iron filings will be mixed in. If they fall directly into the collection bin, it will be difficult to clean up the iron filings. The remaining iron filings can easily scratch the thread surface and affect the quality of the bolts. Therefore, the iron filings must be separated and picked out from the workpiece.

[0003] For example, a chip separator disclosed in Chinese utility model CN202022436938.1 mainly comprises a preliminary separation section extending from a feeding platform, an auxiliary separation section located below the preliminary separation section, a chip dropping port formed between the preliminary separation section and the auxiliary separation section, and a chip collecting seat arranged below the preliminary separation section, the auxiliary separation section and the chip dropping port, wherein the preliminary separation section and the auxiliary separation section respectively have a plurality of screening rods and a dropping gap formed between the screening rods; therefore, the workpiece formed by the forming machine can be separated from the chips by the chip dropping port and the dropping gap during the process of passing through the separation zone. Not only is the structure simple, but the operation can also be used for workpieces of different sizes, thereby increasing the convenience of use.

[0004] Although the workpiece and iron chips are separated by screening the gap between the rods, during separation, due to the different sizes of iron chips, the entanglement of different iron chips, and the iron chips with arcs or spirals or holding on the rod body, the iron chips cannot fall smoothly and hinder the movement of other workpieces, causing multiple iron chips to entangle with each other and block the movement path of the workpiece, affecting the separation efficiency. In addition, the separated iron chips and workpieces are oily, and a separate device is required for sedimentation and oil filtering, which requires secondary transportation and a long sedimentation time and occupies a large area, which is time-consuming and labor-intensive, and has a high production cost.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 The utility model provides a structural schematic diagram of a high-compatibility fixed iron chip oil-water separator.

[0016] Figure 2 for Figure 1 Top view of the highly compatible fixed iron chip oil-water separator. DETAILED DESCRIPTION

[0017] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0018] like Figure 1 to Figure 2 As shown, it is a schematic diagram of the structure of the high-compatibility fixed iron chip oil-water separator provided by the utility model. The high-compatibility fixed iron chip oil-water separator includes a device body 10, a material flow channel 20 arranged on the device body 10, and a chip removal device 30 arranged on the material flow channel 20. It can be imagined that the high-compatibility fixed iron chip oil-water separator also includes some other functional modules such as oil leakage tank, oscillation device, etc., which are well known to those skilled in the art and will not be described one by one here.

[0019] The equipment body 10 is a main body part for supporting the above structures, and can be made of rigid materials such as stainless steel, alloy or cast iron to ensure its stability and reliability. The bottom of the equipment body 10 is connected to a vibration device, such as a vibration motor, so that the iron chips and the workpieces can jump in the chip removal device 30 by vibrating the equipment body 10, thereby separating them.

[0020] The material flow channel 20 is an inclined flow channel for the movement of the workpiece, and includes a feed port 21 located on one side of the equipment body 10 , a discharge port 22 located on the other side of the equipment body 20 , and a chip removal port 23 located between the feed port 21 and the discharge port 22 .

[0021] The feed inlet 21 is located on one side of the equipment body 10 and is connected to the thread rolling machine or the discharge device of the previous process. In this embodiment, the feed inlet 21 is a hopper-shaped structure so that the material will not be ejected from the material flow channel 20 after impact during the feeding operation.

[0022] The discharge port 22 is located in the logistics direction of the feed port 21, and the opening direction is consistent with the inclination direction of the material flow channel 20, so that the material sliding down along the material flow channel 20 can slide out from the discharge port 22. The height of the discharge port 22 from the ground is less than the height of the feed port 21 from the ground, so that after the workpiece enters the material flow channel 20, it will slide from the feed port 21 to the discharge port 22 along the material flow channel 20 under the action of gravity.

[0023] The chip discharge port 23 is located between the feed port 21 and the discharge port 22, is arranged on the bottom surface of the material flow channel 20, and is communicated with the discharge port 22, and the opening direction is perpendicular to the extension direction of the material flow channel 20, so that when passing through the chip discharge port 23, the iron chips screened by the chip discharge device 30 fall from the chip discharge port 23 under the action of gravity.

[0024] The chip removal device 30 includes a screening grid 31 disposed at the chip removal port 23 , a plurality of screening rods 32 disposed at the discharge port 22 , and a collecting box 33 disposed below the chip removal port 23 .

[0025] The screening grid 31 is a plurality of rectangular plates spaced apart in the length direction and laid along the material flow channel 20 at the opening of the chip removal port 23. It is made of stainless steel, alloy or cast iron. The width of the rectangular plate is 10 cm to 20 cm. The width near the end of the feed port 21 is greater than the width near the end of the discharge port 22, that is, the width of the rectangular plate changes from large to small in the direction from the feed port 21 to the discharge port 22, so that a gap from small to large is formed between any two adjacent rectangular plates from the feed port 21 to the discharge port 22. The gap is used to separate the cutting fluid and oil residue on the workpiece from the workpiece surface and discharge it from the gap. Specifically, the width of the gap is 2 mm to 2.5 mm. It is also possible to use rectangular plates of equal width, which are arranged in a fan shape to achieve the same effect, such as the structure adopted by the screening rod 32 below, which will not be repeated here. In addition, in order to obtain a better screening effect, the upper surface of the screening grid 31 away from the collecting box 33 can be an arc-shaped surface, and the edges of the rectangular plate can be chamfered to facilitate iron filings to slide into the gaps of the screening grid 31.

[0026] One end of the screening rod 32 extends toward the discharge port 22, and the other end is connected to the screening grid 31 by welding or other means, and the height of the connection from the ground is less than the height of the upper surface of the screening grid 31 from the ground, so as to form a connection step that is convenient for oil leakage, so that when the workpiece falls into the screening grid 31, it will collide due to the height difference, which is convenient for removing the oil on the surface of the workpiece. The screening rods 32 are all arranged at intervals at the discharge port 22, and the spacing of the rod body at the connection end of the screening grid 31 is less than the spacing of the free end extending to the discharge port 22, that is, the spacing distance between any two adjacent screening rods 32 gradually increases from small to large in the direction from the connection end to the free end, so that the overall distribution is fan-shaped, and the gap size is 4 cm to 8 cm, so that a gap is formed between two adjacent rod bodies that gradually widens from the connection end to the free end, so as to separate larger iron filings. The axial direction of the rod body of the screening rod 32 is consistent with the inclination direction of the material flow channel 20, so as to perform secondary separation on the chip-carrying products separated by the screening grid 31, and the large-sized iron chips that cannot fall from the screening grid 31 can fall in the gap of the screening rod 32. In addition, the cross-sectional shape of the screening rod 32 can be circular or can be a mutually interlocking polygon, which is not specifically limited here. It is conceivable that the gap between the screening rods 32 is smaller than the size of the screw head of the bolt to ensure that the bolt will not fall from the gap with the iron chips.

[0027] The collecting box 33 is arranged below the chip discharge port 23 away from the sieve grid 31, and is spaced apart from the material flow channel 20 and arranged parallel to the ground or the equipment plane to collect the iron chips and cutting fluid leaking from the gap between the sieve grid 31 and the sieve rod 32. It is conceivable that, in order to facilitate the separate collection of oil residue and iron chips, a grid-type collecting box 33 can be provided, one grid is located directly below the sieve grid 31 for collecting oil residue and cutting fluid, and the other grid is located directly below the sieve rod 32 for collecting iron chips. This is something that can be thought of by those skilled in the art, so it is only briefly described in the specification here, and is not illustrated one by one in the drawings of the specification.

[0028] Compared with the prior art, the high-compatibility fixed iron chips, oil and water separator provided by the utility model is provided with the screening grille 31, a wide rectangular plate is used as the main structure of the grille, and a gap is provided, so that the cutting fluid and oil residue can fall from the gap and be collected by the collection box 33. The screening rod 32 is provided to screen the workpiece, separate the iron chips from the workpiece, and improve the separation efficiency. At the same time, the fan-shaped screening rod 32 is provided to effectively avoid the problem that large-sized iron chips are stuck in the gap and cannot fall smoothly.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
