Description

Technical Field

[0001] This utility model relates to a cutting fluid filtration device, specifically a cutting fluid filtration device suitable for multiple working conditions, and belongs to the field of cutting fluid filtration technology. Background Technology

[0002] With the acceleration of modern production pace and the improvement of machine tool processing efficiency, the market demand for non-metallic grinding processing is gradually increasing, and the range of materials involved is also very diverse. In response to different practical needs such as high-precision processing, not only the chip removal and circulation conveying capabilities, but also the filtration accuracy requirements are increasing simultaneously. In particular, the semiconductor / medical / automotive electronics industries have significantly increased their demand for high-precision filtration.

[0003] Existing patent (publication number: CN221752444U) discloses a cutting fluid filtration device. This utility model allows for automatic replacement of the pre-cleaned filter screen by pushing it into the cutting fluid filtration device, eliminating the need for machine downtime. This enables the device to continuously filter cutting fluid during filter replacement, significantly improving filtration efficiency. The operation is simple and quick, enhancing both the device's practicality and user experience. However, in practical use, relying solely on a single filter screen results in the significant variation in particle size and irregular shapes of the debris generated during processing. Filter screens with fixed pore sizes lack adaptability, failing to efficiently intercept fine debris and easily becoming clogged by large, irregular particles. This makes it difficult to thoroughly remove these complex and varied debris particles that can cause wear on equipment or affect cutting fluid performance, ultimately leading to poor filtration. Utility Model Content

[0004] This invention provides a cutting fluid filtration device suitable for various working conditions to address the problem of efficiently and cleanly handling complex, varied, and hazardous grinding debris.

[0005] The present invention achieves the above objectives through the following technical solution: a cutting fluid filtration device suitable for multiple working conditions, including a support platform, a base fixedly installed on one side of the support platform, and a filtration mechanism provided above the base;

[0006] The filtration mechanism includes a stepped overflow chip removal device body, which is fixedly installed on one side of the top of the base, and a conveying pipe network extends through one side of the stepped overflow chip removal device body. A conveying shell is fixedly installed on one side of the support platform, and a vertical paper tape filter body is fixedly installed on one side of the top of the support platform. A filter cylinder is embedded in one side of the outer wall of the support platform, and a temperature control device body is fixedly installed on one side of the vertical paper tape filter body at the top of the support platform. A PLC control cabinet is embedded in the outer wall of the temperature control device body.

[0007] As a further improvement of this utility model: the main body of the stepped overflow chip removal device is connected to the main body of the vertical paper tape filter device through a conveying pipeline, and the main body of the vertical paper tape filter device is connected to the filter cylinder through a conveying pipeline.

[0008] As a further improvement of this utility model: a liquid collection tank is embedded on the other side of the top of the base, and a processing mechanism is provided above the liquid collection tank.

[0009] As a further embodiment of this utility model: the processing mechanism includes a collar, which is sleeved on the bottom end of the filter cylinder, and a guide bucket is fixedly installed at the bottom end of the collar, and a connecting pipe is fixedly installed at the bottom end of the guide bucket.

[0010] As a further embodiment of this utility model: a fixed shell is fixedly installed at one end of the conveying pipeline that enters the filter cylinder, and a drive rod extends out from the inside of the fixed shell. A flow groove is opened on the inner wall of the drive rod, and a servo motor is fixedly installed at the top of the drive rod.

[0011] As a further improvement of this utility model: a bag filter extends from the inside of the filter cylinder, and reinforcing rings are fixedly installed at both ends of the bag filter.

[0012] As a further embodiment of this utility model: a fixing plate is fixedly installed above the reinforcing ring inside the filter cylinder, and a slot is opened on the inner wall of the fixing plate; a locking block is fixedly installed at the top of the reinforcing ring.

[0013] As a further improvement of this utility model: an abutment frame is fixedly installed inside the lower part of the filter cylinder, and a reinforcing rod is fixedly installed on the inner wall of the bag filter.

[0014] The beneficial effects of this utility model are:

[0015] 1. This device, through the coordinated operation of the delivery pipeline network and delivery components such as the booster pump, guides the cutting fluid to flow sequentially through the main body of the stepped overflow chip removal equipment, the main body of the vertical paper tape filter equipment, and the filter cartridge, and is placed after the primary water tank. This process, using a full-flow filtration method, forms a multi-layered filtration process that can accurately intercept particles of different sizes, significantly improving filtration precision, enhancing water quality, and meeting the precision requirements of the machining chamber and spindle outlet for cutting fluid, as well as the media purification needs under diverse operating conditions. Simultaneously, it conforms to the chip removal methods required for machining non-metallic materials, achieving a large-capacity chip removal filtration effect.

[0016] 2. This device uses a locking block on the top reinforcing ring of the bag filter to insert into the slot of the fixing plate. Rotation completes the locking and fixing, ensuring a stable installation that is not easily loosened. The delivery pipeline and the fixing shell are precisely connected to the internal channel of the drive rod via a flow groove, ensuring efficient introduction of cutting fluid into the bag filter for filtration. The drive rod and the fixing shell adopt a rotating locking structure. Driven by a servo motor, the bag filter rotates synchronously, accelerating the cutting fluid penetration rate and reducing filter media clogging through centrifugal force. Filtration efficiency is significantly improved compared to traditional structures. The bottom contact frame provides a limiting constraint on the reinforcing ring, preventing loosening or displacement during rotation and ensuring the long-term effectiveness of the locking structure. During maintenance, simply loosen the collar, lift and rotate the bag filter to release the locking, achieving quick disassembly and significantly shortening filter bag replacement and cleaning time.

[0023] 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 protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, a cutting fluid filtration device suitable for multiple working conditions includes a support platform 1, a base 2 fixedly installed on one side of the support platform 1, and a filtration mechanism 3 arranged above the base 2. The filtration mechanism 3 includes a stepped overflow chip removal device body 301, which is fixedly installed on one side of the top of the base 2. A conveying pipe network 302 extends through one side of the stepped overflow chip removal device body 301. A conveying shell 303 is fixedly installed on one side of the support platform 1. A vertical paper tape filter body 304 is fixedly installed on one side of the top of the support platform 1. A filter cylinder 305 is embedded in one side of the outer wall of the support platform 1. A temperature control device body 306 is fixedly installed on one side of the vertical paper tape filter body 304, and a PLC control cabinet 307 is embedded in the outer wall of the temperature control device body 306. The cutting fluid is conveyed through the stepped overflow chip removal device body 301, the vertical paper tape filter body 304 and the filter cartridge 305, which can filter the cutting fluid multiple times and in layers, improve the overall filtration accuracy, and is suitable for different particles and chips, meeting the requirements of non-metallic material processing chips and water quality. It is suitable for the processing of different parts of large parts, meeting the high precision requirements of cutting fluid for processing non-metallic materials, improving product performance and improving processing accuracy.

[0026] Furthermore, the main body 301 of the stepped overflow chip removal equipment is connected to the main body 304 of the vertical paper tape filter equipment through the conveying pipeline 302, and the main body 304 of the vertical paper tape filter equipment is connected to the filter cylinder 305 through the conveying pipeline 302; the support platform 1 and the base 2 are welded together to provide support for the entire filter device, and the cutting fluid can be conveyed and transferred to the entire filter device through the conveying pipeline 302 and the conveying shell 303, the lifting pump, etc.

[0027] Example 2

[0028] An improvement based on Embodiment 1: A liquid collection tank 4 is embedded on the other side of the top of the base 2, and a processing mechanism 5 is provided above the liquid collection tank 4; the filtered cutting fluid can be guided and transported through the liquid collection tank 4, and guided to the next process in conjunction with another booster pump and the transport pipeline 302.

[0029] Furthermore, the processing mechanism 5 includes a collar 501, which is sleeved on the bottom end of the filter cylinder 305. A guide bucket 502 is fixedly installed at the bottom end of the collar 501, and a connecting pipe 503 is fixedly installed at the bottom end of the guide bucket 502. The filter cylinder 305 is connected to the collar 501 by threads, and can be connected to an external pipeline flange via the guide bucket 502 and the connecting pipe 503, so that the final filtered cutting fluid can be guided out and discharged into the collection tank 4 for delivery to the next process.

[0030] Furthermore, a fixed housing 504 is fixedly installed at one end of the delivery pipeline 302 that enters the filter cylinder 305. A drive rod 505 extends out from the inside of the fixed housing 504. A flow groove 506 is opened on the inner wall of the drive rod 505. A servo motor 507 is fixedly installed at the top of the drive rod 505. At the same time, the delivery pipeline 302 is fixed to the fixed housing 504 and communicates with the drive rod 505 through the flow groove 506, so that the drive rod 505 can be kept rotating while the cutting fluid is flowing.

[0031] Furthermore, a bag filter 508 extends out from the inside of the filter cartridge 305, and reinforcing rings 509 are fixedly installed at both ends of the bag filter 508; the bag filter 508 extends into the filter cartridge 305, and at the same time, the drive rod 505 extends into the inside of the bag filter 508, which can filter the cutting fluid during rotation and improve the overall filtration effect.

[0032] Furthermore, a fixing plate 510 is fixedly installed above the reinforcing ring 509 inside the filter cartridge 305. The inner wall of the fixing plate 510 has a slot 511, and a locking block 512 is fixedly installed at the top of the reinforcing ring 509. The locking block 512 fixed to the reinforcing ring 509 above the bag filter 508 passes through the slot 511 of the fixing plate 510 and engages after rotation, allowing the bag filter 508 to be quickly assembled with the filter cartridge 305.

[0033] Furthermore, an abutment frame 513 is fixedly installed inside the lower part of the filter cartridge 305, and a reinforcing rod 514 is fixedly installed on the inner wall of the bag filter 508. The abutment frame 513 limits the bottom reinforcing ring 509 of the bag filter 508 to prevent the bag filter 508 from becoming loose or shifting, which would cause the slot 511 and the block 512 to become loose. The reinforcing rod 514 is embedded inside the bag structure of the bag filter 508 to improve the overall rigidity and prevent wrinkles or bending during rotation.

[0034] Working principle: The support platform 1 and the base 2 are welded together to provide a stable support foundation for the entire filtration device. Through the coordinated action of the conveying pipeline network 302, the conveying shell 303, and the booster pump, the cutting fluid flows sequentially through the stepped overflow chip removal device body 301, the vertical paper tape filter body 304, and the filter cartridge 305, achieving multi-layer filtration and effectively improving the overall filtration accuracy. It can adapt to the processing needs of particles and debris of different specifications. At the same time, the temperature control device body 306 ensures the temperature stability during the operation of the device. The operating parameters of each component can be programmed and adjusted through the PLC control cabinet 307, making the operation convenient and efficient.

[0035] The filter cartridge 305 and the collar 501 are connected by threads. The collar 501 connects the guide bucket 502 and the connecting pipe 503, and can be flanged to an external pipeline to guide the final filtered cutting fluid to the collection tank 4 for supplying qualified media to subsequent processes. The bag filter 508 is installed inside the filter cartridge 305. The locking block 512 fixed on the top reinforcing ring 509 can be inserted into the locking groove 511 of the fixing plate 510 and locked by rotation, ensuring a stable and reliable installation. The delivery pipeline 302 is fixedly connected to the fixed shell 504. It is connected to the internal channel of the drive rod 505 through the flow groove 506 on the fixed shell 504, ensuring that the cutting fluid can smoothly enter the bag filter 508 for filtration. The drive rod 505 and the fixed shell 504 adopt a rotating locking structure. With the help of the servo motor 507, the drive rod 505 and the bag filter 508 can be driven. The synchronous rotation of the 08 filter enhances the filtration effect while the cutting fluid flows and filters, significantly improving filtration efficiency. To ensure the stability of equipment operation, the reinforcing ring 509 at the bottom of the bag filter 508 is limited and constrained by the contact frame 513, effectively preventing the bag filter 508 from loosening or shifting during rotation and avoiding the detachment and failure of the slot 511 and the locking block 512. The filter bag of the bag filter 508 is internally fitted with a reinforcing rod 514, which greatly improves the overall structural hardness of the filter material and prevents it from wrinkling or bending during high-speed rotation, ensuring the stability of the filtration area and filtration effect. During maintenance, simply loosen the collar 501, lift and rotate the bag filter 508 and the reinforcing ring 509 to release the locking state of the locking block 512 and the slot 511, achieving quick disassembly and assembly, and facilitating the replacement or cleaning of the filter bag of the bag filter 508.
