If the specific resistance value is measured by the measuring device 01j (set at 7, the control device 0) and compared with the 11 specific resistance fo1 (reaches the target value), if 151 sends an electrical signal to the conductive path (1.τ of the waterway switching valve) from the closed position C1) to the oven position (A) (switching this waterway switching valve). stomach)
filtered in the filter (9) by the switching action of flT
For Nishimizu, the oven position (2) of the waterway switching valve
The water is sent to the deionizer (to) via 1. In this water purifier, there is a substance (y) that increases the specific resistance of fresh water (
The specific resistance value of the fresh water is not adjusted, and it is stored in the fresh water tank (4) through piping. be done. (c) is a sewage tank drain valve, and (b) is a 1-hole fresh water tank drain valve. Next, the machining fluid supply system in Figure 1 will be explained in Figure 1.
The T filter (9) will be explained in detail with reference to FIGS. 2 and 8. The filter (9) is stored in the FIi cell a container,
Its configuration is as follows. C27) is the upper lid,
The lower lid - ρ, and the upper lid and lower lid (c) of these two are fixed by boss wires. , (7) is a water tube, and the water tube (1) has many water holes 01) through which clean water passes.The 8mm boss holder and the water tube (1) are integrated. There is. 0's l O-core hole, this 8 hole ((2i and hollow 8 rod (not shown) should not pass through), insert this filter (9) into the machining fluid supply bag!Main body + this installation is done by lowering it.Blu filter It is a protective film for the main body and has many holes on its surface.
Holes of several micrometers are provided. C1tit protection ring protects the filter from external pressure when processing liquid penetrates into the filter from the outside. Next, the flow of the machining fluid will be explained. The machining fluid enters the container housing the filter (9) as shown in Figure 2 through the pipe (8) and passes through the filter (9).
leading to. The -1.rv processing liquid that enters the container passes through the filter protection membrane (c), the filter body ■, and flows through the water passage hole 0η to the water passage tube (
7) At this time, the holes in one filter body (goods) are several μ■
) At this stage, only the machining fluid passes through the filter (b). It becomes clear water. Water bottle! The 11 pieces of fresh water are piped through the hollow part of the core rod formed integrally with the container housing the filter (9).
O leads to the fresh water tank (4). By the way, in the processing liquid supply device constructed as described above, the filter (9) is held between the protective film (c) and the support ring C (5) as shown in FIG. , Furthermore, since the upper cover (a) and the lower cover (c) are integrally fixed to the boss holder, this filter (
9) t-+f: When separating the machining fluid into metal powder and clean water, the filter (b) becomes clogged [7] When the service life is reached, remove the entire filter (9) from the machining fluid supply device. I am replacing the old one with a new one. This has the disadvantage that the filter is expensive and reduces its filtration effectiveness, which makes it difficult to use the filter to its maximum lifespan. This is particularly noticeable with metals such as aluminum, which have strong adhesive properties. Also, in the sewage tank (3), the metal powder in the returning sewage is a fine particle, so the metal powder in the sewage tank is less likely to accumulate in the sewage tank, so the filter (9) is more In order to eliminate the above-mentioned drawbacks of the conventional filters, the filtration life is short.
〆The filter body installed in the filter is configured to be detachable from the filter 7, and the metal powder is removed by washing this filter body [・Reused multiple times] 7. After reaching the end of its service life. The purpose of this invention is to facilitate the maintenance of the filter by replacing only the filter body (lambda) and to reduce this cost.Hereinafter, one embodiment of the present invention will be explained with reference to the drawings, as shown in Fig. 4. 5 is a supply system diagram showing the machining fluid circulation path, FIG. 5 is a side sectional view of the filter section, and FIG. 6 is a sectional view taken along line w-w in FIG. 5. - Toward Fig. 8, T-co shows corresponding parts (these parts are given the same reference numerals and explanations are omitted. (to) is a sewage tank to which machining fluid containing metal powder is returned after being subjected to electrical discharge machining. This sewage tank (this 1.r multiple free weirs (
(b) are arranged parallel to each other so that the bottom surface touches the bottom of the sewage tank (to) in a state where it can be pulled up; A fixed weir with a gap between the bottom and the bottom of the pipe (2) is installed, and the sewage flowing in from the pipe (2) flows between the multiple stages of fixed weir (to) and free weir (b) as shown in the figure. The water flows as shown by arrow A and reaches the position of the pipe (6) where it is pumped up by the offshore pump (7). At this point, the inflow pressure from pipe (2) is
), the metal powder will settle and accumulate at the bottom of the sewage tank (to), and the amount of metal powder contained in the machining fluid fed to the filter (9) will be significant. <Decrease>, the life of the filter can be extended by the same amount. When cleaning the sewage tank, pull up the free weir (b).
] Since the bottom of the sewage tank (to) is open, it can be easily accessed by opening the sewage tank drain valve (a). This filter (9), which will be explained using FIG. 6, has a large number of water holes 01) through which the machining fluid passes, one water pipe G11), and a support disposed locally in this water pipe G11). ring and a filter body (b) disposed around the support ring (to).
It consists of the first upper cover (end) and the lower cover (40, in this case, the lower cover) and the lower cover 00.
A threaded connection screw is formed in the engaging part □□□ of the water tube (41) and is removably screwed to fix the entire filter. The filter body (2) becomes clogged with the processed metal powder, resulting in functional deterioration such as a decrease in the filtration flow rate.In this case, only the filter body (■) must be removed and cleaned. Once the processed metal powder is removed, it can be reused. In addition, the above filter body ■ and water tube G11) ), ? In addition to being screwed in with the connecting screws provided on the upper and lower lids (00), it is also possible to fix them with bolts and nuts that pass through the upper and lower lids (5) and tighten, but this is the same as in the above embodiment. As described above, the present invention has a structure in which the filtration body of the filter that removes only metal powder from the processing fluid containing metal powder is detachably attached to the filter body. It is possible to easily remove metal powder when it decreases, and it is possible to improve the machining performance of electrical discharge machining equipment and reduce the cost of filters.In addition, it is possible to reduce the cost of filters. If it is used in combination with a sewage tank having a sedimentation structure that comes out from a weir and a fixed weir, the metal powder removal effect can be further improved.
