Description
Technical field
The present invention relates to a kind of dry granulating machine, specifically relate to the fast detachment water circulation cooling structure of a kind of dry granulating machine roll, belong to facility for granulating technical field.
Background technology
At present, in pharmaceuticals industry, dry granulating machine is widely used in and carries out processing process to the pharmaceutical raw material of various activity and one or more excipient.Because these raw material major parts are fine powders, its powder size is not of uniform size, Density inhomogeneity, poor fluidity, easily layering, and therefore these raw materials have to pass through granulating process process and just can be used to compressing tablet, capsule-filling or other drug manufacturing procedure.
Dry granulating machine be by two rolls by powder pressing, in compacting process, the air in material is drained, that make even density, solid sheet material.The density of sheet material is apparently higher than the density of powder material.Then roll can produce temperature rise in the course of the work, if do not carry out the process of certain measure to it, will make that material bonds because being heated in pressing process, variable color, rotten.Therefore roll is designed with cooling duct usually, to ensure that the temperature rise that roll produces in running is controlled.
At present; the cooling duct of dry granulating machine roll is opened on roll inwall usually; in order to ensure the sealing between roll and main shaft; roll is fixedly connected with main shaft by the mode of hot jacket again; therefore cooling effect of roller is poor; and it is not easy dismounting, after rolls damage, need integral replacing together with main shaft, considerably increase the maintenance cost of equipment.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of dry granulating machine roll fast detachment water circulation cooling structure, cooling effect of roller is good; effectively can ensure the quality of material; and roll easy accessibility, good seal performance, greatly reduces the maintenance cost of equipment.
The object of the present invention is achieved like this: the fast detachment water circulation cooling structure of a kind of dry granulating machine roll, it comprises main shaft, described front-end of spindle is fixedly installed roll and roller base, described roller base is positioned on rear side of roll, described main shaft (3) rear end offers blind hole, described blind hole is provided with swivel joint, the water inlet pipe of described swivel joint stretches in blind hole, the first sealing ring is provided with between described water inlet pipe front end and blind hole, blind hole is divided into two sections, front and back by described first sealing ring, described roll offers multiple cooling duct vertically, described multiple cooling duct is in series by connection water channel, described roller base and main shaft offer intake tunnel and backwater channel, described intake tunnel one end is connected with the water inlet of the cooling duct after series connection, the described intake tunnel other end is connected with blind hole leading portion, described backwater channel one end is connected with the delivery port of the cooling duct after series connection, the described backwater channel other end is connected with blind hole back segment.
Described swivel joint comprises water inlet, water return outlet, water inlet pipe and return pipe, forms backwater cavity between described water inlet pipe and return pipe, and described blind hole back segment is connected with backwater cavity.
Described roll and roller base are installed on main shaft by pressing plate and locking nut.
Described multiple cooling duct is positioned at circumferentially same.
Described intake tunnel, backwater channel and periphery, cooling duct are provided with the second sealing ring.
Described main shaft is provided with travelling gear.
Compared with prior art, the present invention has following beneficial effect:
The fast detachment water circulation cooling structure of a kind of dry granulating machine roll of the present invention, cooling effect of roller is good, effectively can ensure the quality of material, and roll easy accessibility, good seal performance, greatly reduces the maintenance cost of equipment.
