[technical field]
The utility model relates to sand mill technical field of structures, specifically the cooling rotary sealing appts of a kind of sand mill main shaft.
[background technology]
In materiel machining process, the large flow recirculation system sand of excellent pin formula grinding machine is the most frequently used and the most effective milling apparatus, and it is that the friction, extruding, the collision that utilize abrasive media mutual are carried out grinding distribution to reunion material.Sand mill not only has peptizaiton, but also has the function of extra-fine grinding, and the large flow recirculation system sand of especially excellent pin formula grinding machine is used for grinding that some are ultra-fine, the material of high added value especially.In the process of disperseing at speed lapping, can produce huge heat, plant equipment is sharply generated heat, it is destructive that high temperature like this is starched for the very harsh material of temperature requirement.At present, cooling many employing sand cylinders and the end cap of sand mill are cooling, and grinding spindle does not adopt pressure cooling, the shaft that main shaft self and band pin are excellent in High Rotation Speed and grinding bead and material friction all can produce a large amount of heat, this just makes the overall cooling effect of traditional grinder poor, especially, when in grinding, those are starched for the very sensitive material of temperature, traditional can not meet with the cooling solid main shaft of pressure and shaft the demand that reduces equipment heating amount well.
[utility model content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and provide a kind of sand mill main shaft cooling rotary sealing appts, avoid the large problem of transmission caloric value that traditional sand mill main shaft cannot be cooling, equipment cooling effect is good do not brought, guaranteed that the overall cooling effect of grinder is better.
Design for achieving the above object the cooling rotary sealing appts of a kind of sand mill main shaft, comprise isocon 1, water inlet pipe 2, outlet pipe 10, rotatory sealing 3, main shaft 4 and shaft 8, described rotatory sealing 3 is provided with water inlet and delivery port, described water inlet connects water inlet pipe 2, described delivery port connects outlet pipe 10, described water inlet pipe 2, outlet pipe 10 is connected on isocon 1, described main shaft 4 is hollow shaft, described main shaft 4 head ends and rotatory sealing 3 is connected, described main shaft 4 ends are connected with shaft 8, described main shaft 4 ends are provided with the two equally distributed inlet opening 7 of row and apopores 6, described shaft 8 is hollow shaft, the inlet opening 7 of the hollow parts of described shaft 8 and main shaft 4 ends, apopore 6 is connected, in described rotatory sealing 3, be provided with penstock 5, the water inlet end of described penstock 5 connects water inlet pipe 2, the water side of described penstock 5 connects the inlet opening 7 of main shaft 4 ends.
Described rotatory sealing 3 bottom are provided with mounting bracket 9, described rotatory sealing 3 detachable being connected on mounting bracket 9.
Described inlet opening 7, apopore 6 are made even circumferential along main shaft 4 end outer walls respectively and are distributed.
Described inlet opening 7, apopore 6 are respectively equipped with four.
The utility model compared with the existing technology, simple in structure, reasonable in design, force cooling hollow spindle and hollow shaft owing to adopting band, reduce greatly the temperature of transmission main shaft and shaft, solved the large problem of transmission caloric value, made the overall cooling effect of grinder better; And, especially during for very sensitive, the harsh high added value material of temperature slurry and high efficiency, can very stably guarantee quality and the effect of extra-fine grinding in extra-fine grinding; In addition, forced cooling device novel structure described in the utility model, detachable, installation and maintenance are used all very convenient, are worthy of popularization.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
In figure: 1, isocon 2, water inlet pipe 3, rotatory sealing 4, main shaft 5, penstock 6, apopore 7, inlet opening 8, shaft 9, mounting bracket 10, outlet pipe.
[specific embodiment]
Below in conjunction with accompanying drawing, the utility model is done to following further illustrating:
As shown in Figure 1, the utility model comprises: isocon 1, water inlet pipe 2, outlet pipe 10, rotatory sealing 3, main shaft 4 and shaft 8, rotatory sealing 3 is provided with water inlet and delivery port, water inlet connects water inlet pipe 2, delivery port connects outlet pipe 10, water inlet pipe 2, outlet pipe 10 is connected on isocon 1, thereby compulsory circulative cooling pipeline forms convection current, main shaft 4 is hollow shaft, main shaft 4 head ends and rotatory sealing 3 is connected, main shaft 4 ends are connected with shaft 8, main shaft 4 ends are provided with the two equally distributed inlet opening 7 of row and apopores 6, this inlet opening 7, apopore 6 is made even circumferential along main shaft 4 end outer walls respectively and is distributed, inlet opening 7, apopore 6 is respectively equipped with four, shaft 8 is hollow shaft, the inlet opening 7 of the hollow parts of shaft 8 and main shaft 4 ends, apopore 6 is connected, in rotatory sealing 3, be provided with penstock 5, the water inlet end of penstock 5 connects water inlet pipe 2, the water side of penstock 5 connects the inlet opening 7 of main shaft 4 ends, rotatory sealing 3 bottom are provided with mounting bracket 9, rotatory sealing 3 detachable being connected on mounting bracket 9, this rotatory sealing head is fixed on the machine by mounting bracket.
