Abstract
The utility model relates to a molten metal filtering device, comprising a silica sol funnel type shell and a filter screen, wherein the lower end of the silica sol funnel type shell is provided with a pouring gate; and the filter screen is embedded into the pouring gate. The molten metal filtering device is convenient to operate; and by using the molten metal filtering device, the defect that the filter screen cannot be repeatedly used is overcome, the single filter screen can be repeatedly used over five times, the filter screen cost can be reduced by over 80%, and the production cost can be greatly reduced.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of molten metal filter.
Background technology
In Foundry Production, dreg defect affects casting quality, uses the screen pack can purify hot metal, greatly reduces the risk of dreg defect, but the increase that has simultaneously brought production cost.In hot investment casting is produced, the conventional molten steel filter method using is in cup, to add screen pack when cast, once needs to consume 1 screen pack, causes screen pack not reuse, and has greatly increased production cost, and has caused energy waste.
In view of this, need to invent a kind of can recycling, make simple, molten metal filter easy to use.
Utility model content
The technical problems to be solved in the utility model is to provide one to reduce production costs, and improves screen pack recycling number of times, molten metal filter easy to use.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of molten metal filter, comprises the Ludox funnel shell and the screen pack that be embedded at described running channel inside of lower end with running channel.
As further improvement of the utility model, described in set the running channel at screen pack place diameter be greater than running channel diameter bottom.
Compared with prior art, the beneficial effect that the utility model is obtained is:
The utility model has solved the deficiency that screen pack can not reuse, easy to operate, can make single screen pack reusable more than 5 times, saves screen pack cost more than 80%, has greatly reduced production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the accompanying drawings: 1 funnel shell, 2 running channels, 3 screen packs.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, a kind of molten metal filter, comprises lower end with the Ludox funnel shell 1 of running channel 2 and is embedded at the screen pack 3 of described running channel 2 inside, described in set the running channel 2 at screen pack 3 places diameter be greater than running channel 2 diameter bottom.Such structure can play good fixation to filter screen.
Manufacture craft of the present utility model is specific as follows:
The screen pack of buying on market 3 is improved, adopt full form casting process to make special shell, screen pack is fixed in shell, during use, the utility model is placed on the cup that needs cast product shell, after being poured, the cup top that homemade filter screen device is moved on to the shell that next time needs cast continues to use.
Concrete manufacturing process is as follows:
The first step: the common screen pack 3 of first buying being returned is put into particular manufacturing craft, then injects wax material in mould, and screen pack 3 is wrapped in wax-pattern.
Second step: adopt Ludox technique to make shell the wax-pattern that contains screen pack 3 making, concrete operations are as follows: surface layer adopts Ludox, zircon flour coating, spreads 120 order zircon sands; 2 layers and 3 layers adopt Ludox, do not carry out powder coating, spread 30-60 order and do not carry out sand; 4 layers and 5 layers adopt Ludox, do not carry out powder coating, spread 16-30 order and do not carry out sand; 6 layers adopt Ludox, do not carry out powder coating, powder is only coated with not stucco of coating.
The 3rd step: dried silicasol case is put into dewaxing kettle wax material is deviate from, form molten metal filter provided by the utility model.
The above embodiment is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the present invention.For persons skilled in the art, any apparent change of under the prerequisite that does not deviate from the utility model principle and spirit, it having been done, within all should being contemplated as falling with claim protection domain of the present utility model.
Claims (2)
1. a molten metal filter, is characterized in that it comprises lower end with the Ludox funnel shell (1) of running channel (2) and is embedded at the screen pack (3) in the middle part of described running channel (2).
2. a kind of molten metal filter according to claim 1, the diameter of setting the running channel (2) that screen pack (3) locates described in it is characterized in that is greater than running channel (2) diameter bottom.
