Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a wire cutting coolant recovery and filtration device. Background Art

[0002] Wire cutting is a precision machining method for material removal based on the principle of electric spark discharge. During the machining process, coolant is required to perform functions such as insulation, cooling, and chip removal. Since the coolant will be mixed with metal chips and other impurities during use, it needs to be filtered and purified regularly to ensure the machining quality and the service life of the equipment. However, the existing coolant recovery equipment only performs large-particle filtration and impurity removal. When the coolant is directly recycled and used, ferromagnetic metal powders, small-particle impurities, and oil stains still remain, which will affect the effect of the coolant during wire cutting. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a wire cutting coolant recovery and filtration device to solve the problem that impurities still remain when the existing coolant is recycled and used, which will affect the effect of the coolant.

[0004] A wire cutting coolant recovery and filtration device in this solution includes a filtration tank, and a primary filtration mechanism, a secondary filtration mechanism, and a depth filtration mechanism are arranged in the filtration tank. The primary filtration mechanism is used for filtering large-particle metal debris, the secondary filtration mechanism is used for filtering ferromagnetic metal powders, and the depth filtration mechanism is used for filtering oil stains and organic matters.

[0005] The working principle and beneficial effects of this solution: After the existing wire cutting machine finishes cutting, the used coolant is directly placed into the filtration tank and enters from the top of the filtration tank. After the primary filtration mechanism recovers the large-particle metal debris, the coolant continues to the secondary filtration mechanism, and the secondary filtration mechanism filters the ferromagnetic metal powders in the coolant. Finally, the depth filtration mechanism filters the oil stains, so that the coolant can be decontaminated three times and then can be directly recycled and used again.

[0006] Further, the primary filtration mechanism is a filter screen. The filter screen directly filters large-particle impurities and filters out the large-particle impurities and debris together.

[0007] Further, the secondary filtration mechanism is a magnetic adsorption filter disc, and the material of the magnetic adsorption filter disc is a magnet. The magnetic adsorption filter disc is used for adsorbing metal powders, and the metal powders passing through the magnetic adsorption filter disc are adsorbed by the magnetic adsorption filter disc, so as to achieve the effect of removing ferromagnetic metal powders in the coolant.

[0008] Furthermore, the thickness of the magnetic adsorption filter disc gradually increases from the center to the periphery. Since the magnetic adsorption filter disc gradually thickens from the center to the periphery, the magnetism gradually increases, and the force for adsorbing ferromagnetic metal powder is greater at the periphery. When the coolant drops onto the magnetic adsorption filter disc, more metal powder is adsorbed near the outer extension of the magnetic adsorption filter disc, thus avoiding the situation where the surface of the magnetic adsorption filter disc is completely blocked after adsorbing metal powder.

[0009] Furthermore, the depth filtration mechanism includes a filter box, and the interior of the filter box is filled with activated carbon particles. The activated carbon particles in the filter box are used to remove oil stains and organic substances. Description of the Drawings

[0010] Figure 1 It is a schematic structural diagram of a wire cutting coolant recycling and filtering device of the present utility model. Detailed Embodiments

[0011] The following will be further described in detail through specific embodiments:

[0012] The reference numerals in the accompanying drawings of the specification include: filter box 1, opening 2, filter screen 3, magnetic adsorption filter disc 4, filter box 5, activated carbon particles 6.

[0013] The embodiment is basically as shown in the attached Figure 1 figures: A wire cutting coolant recycling and filtering device includes a filter box 1, an opening 2 is provided at the top of the filter box 1, and a primary filtration mechanism, a secondary filtration mechanism and a depth filtration mechanism are provided inside the filter box 1;

[0014] The primary filtration mechanism is a filter screen 3;

[0015] The secondary filtration mechanism is a magnetic adsorption filter disc 4, the material of the magnetic adsorption filter disc 4 is a magnet, and the thickness of the magnetic adsorption filter disc 4 gradually increases from the center to the periphery;

[0016] The depth filtration mechanism includes a filter box 5, and the interior of the filter box 5 is filled with activated carbon particles 6.

[0017] After the existing wire cutting machine finishes cutting, the used coolant is directly placed into the filtration tank 1, entering from the top of the filtration tank 1. The filter screen 3 directly filters large-particle impurities, filtering out the large-particle impurities and debris together. The magnetic adsorption filter disc 4 is used to adsorb metal powder. All the metal powder passing through the magnetic adsorption filter disc 4 is adsorbed by the magnetic adsorption filter disc 4, thus realizing the function of removing ferromagnetic metal powder in the coolant. The center of the magnetic adsorption filter disc 4 gradually becomes thicker towards the periphery, so the magnetism gradually increases, and the force for adsorbing ferromagnetic metal powder at the periphery is greater. When the coolant drops onto the magnetic adsorption filter disc 4, more metal powder is adsorbed near the outer extension of the magnetic adsorption filter disc 4. In this way, it can be avoided that after the surface of the magnetic adsorption filter disc 4 adsorbs metal powder, the surface of the magnetic adsorption filter disc 4 is completely blocked. Finally, the activated carbon particles 6 in the filter box 5 are used to remove oil stains and organic substances, so that the coolant can be purified three times and then directly recycled and reused again.

It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
