The invention discloses a coil pipe type ferromagnetic abrasive dust separating device. More than one group of coil pipe type electromagnetic absorbing devices in the same structure is connected in parallel between a grinding fluid inlet duct and a grinding fluid outlet duct; each coil pipe type electromagnetic absorbing device in the same structure comprises two connectors and a ferromagnetic coil pipe externally wound with a magnet exciting coil; both ends of the magnet exciting coil are respectively connected with a positive power supply and a negative power supply; and one end of the ferromagnetic coil pipe is communicated with the grinding fluid inlet duct through a first fitting and a first valve, and the other end is communicated with the grinding fluid outlet duct through a second fitting and a second valve. The coil pipe type electromagnetic absorbing devices is deteachable, and can realize the continuity of a machining process and recycling. Due to the adoption of the ferromagnetic coil pipe to form turbulent flow of a grinding fluid, the absorption and separation effect on the abrasive dust is enhanced. The invention can overcome the disadvantages of poor separation effect, improper collection treatment of the abrasive dust, large size and the like of a traditional abrasive dust separating device.

Technical field
The present invention relates to a kind of ferromagnetism abrasive dust gathering-device, especially relate to a kind of coil pipe type ferromagnetic abrasive dust gathering-device.
Background technology
The ferromagnetism abrasive dust be meant that the part of ferrimagnet produces in grinding process fine particle, abrasive dust is present in the grinding fluid, causes piece surface to scratch easily, thereby influences surface quality of workpieces, causes that part is defective to be scrapped.Ferromagnetism abrasive dust isolation technics just is based on this background generation.Present ferromagnetism abrasive dust separation principle mainly contains: isolated by filtration principle, gravity settling separation principle, centrifugal sedimentation separation principle, electromagnetism absorption principle etc.Have a variety ofly based on the abrasive dust separating device of above several principles, but effect is not very desirable, mainly contains following several defective: separating effect is bad, the abrasive dust collection and treatment is improper, separator bulky etc.
Summary of the invention
The object of the present invention is to provide a kind of coil pipe type ferromagnetic abrasive dust gathering-device, avoid the various disadvantages of ferromagnetism abrasive dust separating device in the past,, improve the part qualification rate in the hope of improving the surface quality of grinding part.
The technical solution used in the present invention is:
The coiled electromagnetism adsorbent equipment that structure is identical more than one group in parallel between grinding fluid inlet duct and grinding fluid outlet conduit; The coiled electromagnetism adsorbent equipment that described structure is identical includes two joints, and the outside is wound with the ferromagnetism coiled pipe of magnet exciting coil; The two ends of magnet exciting coil connect positive and negative power supply respectively, and an end of ferromagnetism coiled pipe is communicated with the grinding fluid inlet duct through first joint and first valve, and the other end of ferromagnetism coiled pipe is communicated with the grinding fluid outlet conduit through second joint and second valve.
The group number of the coiled electromagnetism adsorbent equipment that parallel-connection structure is identical between described grinding fluid inlet duct and the grinding fluid outlet conduit is 2～4 groups.
The beneficial effect that the present invention has is:
1) the coil pipe type ferromagnetic abrasive dust gathering-device is simple in structure, and Costco Wholesale is low.
2) the present invention is based on theoretical ripe electromagnetism absorption principle, actual workable.
Produce turbulent flow when 3) the adsorption tube layout of coiled of the present invention can cause grinding fluid to flow in pipeline, thereby strengthen the abrasive dust separating effect.
4) the present invention adopts coiled electromagnetism adsorbent equipment,, can dismantle this device easily and carry out the cleaning of abrasive dust owing to the passing of working time, when adsorption effect weakens, close the valve of this device when a device, thereby the recovery of implement device is reused.
5) the present invention can be by changing each valve folding condition, and the replacing of implement device guarantees the continuity of grinding technique simultaneously.
In a word, the coil pipe type ferromagnetic abrasive dust gathering-device can effectively be avoided the defective in the background technology, the ferromagnetism abrasive dust is collected principle and is only collected the ferromagnetism abrasive dust, and do not adsorb the fine particle that grinds oilstone, help reducing the roughness of grinding piece surface, and do not scratch piece surface, thereby help improving the part qualification rate.The present invention can avoid defective such as abrasive dust separating device such as separating effect is bad, the abrasive dust collection and treatment is improper, separator bulky in the past.

The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and instantiation.
As shown in drawings, the identical coiled electromagnetism adsorbent equipment of two groups of structures in parallel between grinding fluid inlet duct 1 and grinding fluid outlet conduit 9.First group of coiled electromagnetism adsorbent equipment 5 comprises first joint, 3, the second joints 7, and the outside is wound with the first ferromagnetism coiled pipe 4 of first magnet exciting coil 6; The two ends of first magnet exciting coil 6 connect positive and negative power supply respectively, one end of the first ferromagnetism coiled pipe 4 is communicated with grinding fluid inlet duct 1 through first joint 3 and first valve 2, and the other end of the first ferromagnetism coiled pipe 4 is communicated with grinding fluid outlet conduit 9 through second joint 7 and second valve 8.Second group of coiled electromagnetism adsorbent equipment 13 comprises the 3rd joint 11, the four joints 15, and the outside is wound with the second ferromagnetism coiled pipe 12 of second magnet exciting coil 14; The two ends of second magnet exciting coil 14 connect positive and negative power supply respectively, one end of the second ferromagnetism coiled pipe 12 is communicated with grinding fluid inlet duct 1 through the 3rd joint 11 and the 3rd valve 10, and the other end of the second ferromagnetism coiled pipe 12 is communicated with grinding fluid outlet conduit 9 through the 4th joint 15 and the 4th valve 16.
The group number of the coiled electromagnetism adsorbent equipment that parallel-connection structure is identical between described grinding fluid inlet duct 1 and the grinding fluid outlet conduit 9 is 2～4 groups.Concrete number is by processing technology and the decision of processing situation.
The joint number of ferromagnetism coiled pipe is more than 2 joints or 2 save, and concrete joint number is by the requirement decision of abrasive dust separation degree.
Operation principle of the present invention is as follows:
Grinding fluid flows into from the direction of arrow shown in the accompanying drawing, when grinding begins, open first valve 2 and second valve 8, close the 3rd valve 10 and the 4th valve 16, promptly choose first group of coiled electromagnetism adsorbent equipment 5, because the layout of snakelike form, the joint number of ferromagnetism coiled pipe is 2 joints, mobile the be turbulent flow of grinding fluid in pipeline, after 6 energisings of first magnet exciting coil, the first ferromagnetism coiled pipe 4 and abrasive dust are magnetized, abrasive dust in the grinding fluid is attracted around the first ferromagnetism coiled pipe, 4 inner-walls of duct, after work a period of time, along with the accumulation of duct wall abrasive dust, the separation adsorption capacity of this first group of coiled electromagnetism adsorbent equipment 5 descends, close first valve 2 and second valve 8 for guaranteeing the continuation of processing this moment, opens the 3rd valve 10 and the 4th valve 16, promptly choose second group of coiled electromagnetism adsorbent equipment 13 this moment, and the course of work is identical with first group of coiled electromagnetism adsorbent equipment 5.So far, can dismantle down first group of coiled electromagnetism adsorbent equipment 5 easily the abrasive dust in its pipeline is handled, so that reuse in the future.
