Description

Machine tool and cutting fluid filtering device

Technical Field

The utility model relates to a lathe technical field especially relates to a lathe and cutting fluid filter equipment.

Background

As is known, during machining of machine tools, it is necessary to spray cooling fluid for cooling, lubricating and flushing the cutting. Chips and cutting fluid in the cutting process of the machine tool are mixed together and flow into the cutting fluid box. The cutting fluid may be a coolant, a lubricant, a liquid having a cooling effect, a liquid having a lubricating effect, a liquid having a flushing effect, or other auxiliary liquid used for cutting or cutting. If the cutting fluid obtained by mixing the chips and the cutting fluid is directly poured into lakes and rivers, water pollution is inevitably caused. Therefore, how to separate solid and liquid components in the cutting fluid is a technical problem.

In the prior art, filtration and separation are generally performed according to differences of processing objects and processing techniques and according to shapes, sizes or specific gravities of formed chips, for example, one strategy in a mechanical design manual and a machine tool design manual is as follows: respectively filtering particles in various proportions in the cutting fluid according to the size and specific gravity of the cutting chips; in the occasion with larger cutting amount, a further strategy is to adopt a chip removal machine to filter cutting fluid, automatically transfer and discharge the chips separated by filtering into a chip collection box, and finally press the chips into cakes so as to reduce the space occupation; in the grinding field, for example, the hard and brittle materials in the glass and sapphire fields and the like, a centrifugal filter with automatic slag discharge is adopted after chemical precipitation; magnetic conductive material such as pure steel material is processed, and magnetic conductive cuttings in the cutting fluid are separated by magnetic adsorption.

In conclusion, the design of all cutting fluid filtering and cutting slag collecting devices always surrounds the filtering precision, namely the passing property of the particle size or the particle ratio in the cutting fluid; the filtration efficiency is the return flow of the cutting fluid or the interception of the cuttings in unit time; the post-treatment efficiency, i.e. the time taken to treat the filtered swarf slag or the time required for the machine to be shut down to treat the swarf and clean the filter box, spreads.

However, the current high-efficiency processing machine tool generates more than several times or even more than ten times of fine cutting chips in unit time compared with the conventional machine tool, and the flow rate of the cutting fluid is larger than that of the past, if the cutting fluid is directly collected by a conventional chip collecting box, the problems are that: firstly, insufficient filtration is easily caused, and part of cuttings are not filtered; secondly, collection bits box is bulky, just has certain holding capacity, but great collection bits box can be comparatively heavy, is difficult to carry, and it is troublesome to change collection bits box, and the operability is poor, and it is higher to purchase a large amount of collection bits box costs. Moreover, the filter screen of collection bits box is too close easy stifled, and too rare filterability is poor, and the multiaspect is seted up the filter screen and can be gathered bits box or sink and dip in the water tank, or increase the water tank height, so set up can make clearance, maintenance waste time and energy, the clearance filter screen of regularity still leads to gathering bits box and damages easily, and the smear metal sediment is leaked.

Therefore, it is desirable to provide a cutting fluid filtering device, which effectively solves the problems of insufficient filtering, inconvenient cleaning and high maintenance cost.

Referring to fig. 1 and 2, an embodiment of a cutting fluid filtering apparatus provided by the present invention includes:

the cutting fluid collection and filtration device comprises a first filter bag 211 for collecting chips in a cutting fluid, a hollow slag basket 212, a second filter bag 213 for collecting chips in the cutting fluid flowing through the hollow slag basket 212 and a chip collection and filtration box 21;

the opening of the first filter bag 211 is upward and is arranged in the inner cavity of the hollow slag basket 212; the second filter bag 213 has an upward opening and is arranged in the inner cavity of the scrap collecting filter box 21; the hollow slag basket 212 is disposed in the cavity of the second filter bag 213.

In this embodiment, the first filter bag 211 is used for collecting chips in the cutting fluid, and the first filter bag and the hollow slag basket 212 form a first filter layer; the second filter bag 213 is used for collecting the cuttings in the cutting fluid flowing through the hollow slag basket 212, and the cuttings collecting filter box 21 forms a second filter layer; the two filtering layers are independent, the first filtering bag 211 can be detached from the hollow slag basket 212, and the hollow slag basket 212 and the scrap collecting filtering box 21 both play a supporting role. The second filter bag 213 is detachable from the dust-collecting filter cassette 21. When the cutting fluid flows through the first filter bag 211, a part of the chips may enter the second filter bag 213 from the first filter layer due to the replacement or breakage of the first filter bag 211, leakage or overflow, and the like, and the second filter bag 213 effectively filters the chips. When the first filter bag 211 is full and the first filter bag 211 is replaced without stopping, the first filter bag 211 can be directly extracted, and the first filter bag is cleaned and then is replaced or another first filter bag is replaced to continue filtering; in the process, part of the unfiltered cutting fluid may enter the second filter layer; the second filter bag 213 filters it, providing redundancy. When the second filter bag 213 is full, it can be cleaned directly from the second filter layer and replaced, or another second filter bag can be replaced to continue filtration. The two filter layer structures not only fully filter cuttings, facilitate the replacement of filter bags and the convenient cleaning, but also ensure the filtration without stopping; only the filter bag is replaced, and the maintenance money cost and the maintenance time cost are reduced.

It should be noted that, first filter bag and second filter bag, including but not limited to the nylon filter bag, the nylon filter bag can be used many times, even damaged scrap cost also very cheap, and nylon belongs to recoverable material, also is comparatively environmental protection.

The opening is upward, not vertical in absolute sense, but may have an inclination angle, which means that the cutting fluid is filtered from top to bottom, unlike the lateral flow. The fretwork sediment basket in this embodiment can have a plurality of faces, including bottom surface and side (lateral wall), and this fretwork sediment basket is one or more face fretworks, and one or more face promptly is provided with one or more through-hole.

The following further explains the embodiment of the cutting fluid filtering device provided by the utility model:

the side wall and the bottom of the hollow slag basket 212 are hollow;

the walls and bottom of the first filter bag 211 coincide with the walls and bottom of the hollow slag basket 212.

The number of the side walls of the hollowed-out slag basket 212 depends on the shape of the basket body, and all or part of the side walls can be hollowed out. As a preferable example, the hollow slag basket 212 may be a container available from the market at a low price, and five surfaces of the bottom and four side walls of the hollow slag basket 212 are hollow structures, so that the cutting fluid can be scattered from five surfaces of the four side walls and the bottom of the hollow slag basket 212 after passing through the first filter bag 211, thereby increasing the water passing area, and increasing the area range of the bottom flow of the chip collecting filter box 21 passing through the second filter bag 213, so that the cutting fluid does not stagnate in the hollow slag basket 212 and the chip collecting filter box 21. The side wall and the bottom are hollowed, which is very beneficial to the filtration efficiency of the cutting fluid with large flux.

It should be noted that the overlapping in this embodiment is intended to be the contact or approach between two surfaces; that is, the two surfaces may be integrally attached to each other or may be integrally close to each other, or may be partially attached to each other or partially close to each other. The bag wall and the bottom of the first filter bag 211 are overlapped with the side wall and the bottom of the hollow slag basket 212, so that the first filter bag 211 is opened, and the filtering area is increased. For example, when the nylon filter bag is as for the fretwork sediment basket, because the characteristic of nylon, the nylon filters a plurality of regional contacts of bag or is close to the fretwork sediment basket, and from the whole, the nylon filters five sides coincide of bag and fretwork sediment basket. In use, the flow of liquid will cause the areas to change in contact or proximity, but still be congruent as a whole. The overlap occurs as follows and is not described in detail.

the side face of the scrap collecting filter box 21 is sealed, the bottom of the scrap collecting filter box 21 is provided with a filtering steel wire mesh 214, the bag wall of the second filter bag 213 is overlapped with the side wall of the scrap collecting filter box 21, and the bottom of the second filter bag 213 is overlapped with the filtering steel wire mesh 214.

In this embodiment, the water flowing out from the bottom of the hollow slag basket 212 can overflow and disperse to the scrap collecting filter box 21 through the steel wire filter net 214, so as to enhance the drainage and water passing effect. The multilayer filtering device can comprehensively block the particles with small sizes, the particle filtering is more complete, and the filtering precision is higher.

It should be noted that the filtering steel wire mesh 214 is arranged at the bottom of the scrap collecting and filtering box 21, and the side surface is sealed, so that the cuttings are favorably deposited at the bottom of the second filter bag 213 corresponding to the bottom of the scrap collecting and filtering box 21, and the cuttings are favorably collected; moreover, the hollow slag basket 212 is arranged in the cavity of the second filter bag 213, and the side surface of the scrap collecting filter box 21 is sealed, so that the first filter bag 211 is not spilled outside when being replaced, and the scrap collecting filter box 21 can be higher than the liquid storage tank of the circulating filter water tank 20. The filtering wire mesh 214 may be replaced with other mesh materials. Alternatively, it is within the scope of reasonable interpretation to provide a through hole in the bottom of the debris-collecting filter box 21. The bag wall and the bottom of the second filter bag 213 are overlapped with the scrap collecting filter box 21 and the filter steel wire mesh 214, so that the filter area can be increased.

In actual operation, the filtering precision level can be controlled only by setting different mesh numbers of the filter bags; the particle ratio in the jet cutting fluid can be controlled by setting the filtration stage number; by these reasonable combinations, better filtration efficiency can be obtained.

In practical application, the filtering holes of the first filtering bag 213 are small, and the diameter of the passing cutting slag is small; while the second filter bag 211 has larger filter holes and larger diameter size for passing the cutting scraps. So that the flow rate is accelerated by the single side being hydrophobic. The first filter bag 213 can be made of 65-85 mesh nylon mesh, preferably 80 mesh; the second filter bag 211 may be made of 45-65 mesh nylon mesh, preferably 60 mesh.

A hydrophobic layer 215 is laid between the filtering steel wire mesh 214 and the second filter bag 213. The side wall and the bottom of the hollow slag basket 212 are hollow, so that the cutting fluid can rapidly flow to the second filter bag 213; the side surface of the chip-collecting filter box 21 is sealed, so that the cutting fluid is efficiently drained and guided by the hydrophobic layer 215.

the number of the first filter bags 211 is more than two, and the first filter bags are stacked in the inner cavity of the hollow slag basket 212.

In this embodiment, after the first filter bag 211 in the hollow slag basket 212 is filled with the cutting waste, the first filter bag 211 can be pulled out of the hollow slag basket 212, and the cutting waste in the bag is poured out and then is placed again; alternatively, a new first filter bag 211 may be installed immediately upon lifting, and the first filter bag may be lifted after installation. As a preferred scheme, more than two first filter bags 211 are stacked in advance in the inner cavity of the hollow slag basket 212, the first filter bag 211 sleeved at the top is pulled out after the cutting slag is fully collected, that is, the next first filter bag 211 is replaced and used, the cutting slag is poured out, the cleaned first filter bag 211 is reserved, and the damaged first filter bag 211 is discarded. Of course, the hollow slag basket 212 may be removed as a unit to clean the chips.

The other first filter bags 211 in the hollow slag basket 212 continue to be used until all of the first filter bags 211 in the hollow slag basket 212 are used up, and then a plurality of first filter bags 211 are filled in, and the process is repeated. The cleaning of the cutting scraps becomes simpler and more convenient, the machine tool can be operated without stopping, the efficiency of cleaning the cutting scraps is improved, the stopping time is avoided, and the cost is very low.

The second filter bag 213 in the scrap filter box 21 is mainly used for stopping the leaked cutting scraps caused by the breakage of the first filter bag 211, the cutting scraps possibly leaked when the hollow slag basket 212 is operated or the first filter bag 211 is pulled, and a small amount of cutting scraps which are not stopped by the first filter bag 211 are used for further filtering and collecting, thereby forming redundancy. The cleaning manner of the second filter bag 213 may be the same as that of the second filter bag 213, and will not be described in detail. Except that the first filter bag 211 has filtered most of the cuttings and the second filter bag 213 will be used longer with a longer cleaning interval period.
