Abstract
The invention discloses a mill feeding multi-seal system. The mill feeding multi-seal system comprises a feeding lining. The feeding lining is connected to a feeding end cover. A large end of an inner cavity of the feeding lining is a tapered surface. The surface of a small end of the feeding lining is connected to a feeding pipe stretching into the inner cavity of the feeding lining by an adjustable pressing cap. Two sealing units are respectively arranged among the adjustable pressing cap, the feeding lining and the feeding pipe and between the adjustable pressing cap and the feeding pipe. At least one groove and a boss cooperating with a discharge end of the feeding pipe are arranged in the inner cavity of the feeding lining. The boss and the at least one groove form a labyrinth seal structure with the discharge end of the feeding pipe. The mill feeding multi-seal system has the advantages that the adjustable pressing cap can be subjected to on-line adjustment so that an asbestos filling material can be compacted continuously in mill running and thus a feeding sealing property is guaranteed; the tapered surface and the labyrinth seal structure arranged in front of an asbestos filling material sealing unit greatly reduce asbestos filling material wearing and a sealing ring sealing unit is arranged in back of the asbestos filling material sealing unit so that sealing effects are good and a feeding end sealing life is prolonged; and the frequency of mill stopping is reduced obviously so that production efficiency is improved.
Description
Technical field
The present invention relates to a kind of sealing system, the multi-sealed system of especially a kind of grinding machine charging.
Background technology
Because material particular diameter is bigger, quickened the wearing and tearing of feed end sealing at the grinding machine feed end, using at present more general has the sealing of stationary gland formula, inserts elastic seal ring and various forms install multi-sealed circle sealing additional at material pipe feed end structure at labyrinth seal ring; Above structure is complex structure not only; And all adopt and insert encapsulant and seal, along with the continuous operation of grinding machine, encapsulant can constantly wear and tear; And gland cannot onlinely be adjusted crush again; Cause the sealing property degradation failure, depend on the rub proofness of encapsulant its sealing life, service life is not long; Cause the grinding machine feed end to leak out, leak powder, spillage, the frequent change encapsulant has had a strong impact on the production efficiency of grinding machine.
Summary of the invention
The present invention is in order to remedy the deficiency of prior art; Provide a kind of grinding machine charging multi-sealed system; This system adopts frame for movement to stop the wearing and tearing of most of material to airtight and watertight padding from the source, this performance does not receive the influence of grinding machine length running time, advances the wearing and tearing of grind materials to encapsulant thereby alleviated greatly; Prolonged sealing life, the replacement cycle obviously shortens.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
The multi-sealed system of a kind of grinding machine charging; It comprises the charging lining; Said charging lining connects with the charging end cap; The big end of charging lining inner chamber is a taper surface, but connects through pressure regulating cover between the small end face of charging lining and the feed pipe that stretches into charging lining inner chamber, but but and be provided with two resealings altogether between pressure regulating cover, charging lining and the feed pipe and between pressure regulating cover and the feed pipe; The step that is provided with at least one groove and matches with the feed pipe discharge end in the said charging lining inner chamber, said step and groove and feed pipe discharge end form labyrinth seal.
The small end face of said charging lining is provided with the hole that supplies feed pipe to get into, and the outer rim in hole is provided with V-shaped groove.
But said pressure regulating cover connects through adjustment bolt and the charging lining small end face outside, but pressure regulating cover be provided with the charging lining on the inclined-plane that matches of V-shaped groove, and the endoporus that passes of confession feed pipe, the inwall of endoporus is provided with at least one rectangular loop groove.
But the gap is not more than 5mm between the endoporus of said pressure regulating cover and the feed pipe.
But said pressure regulating cover is pressed into to cooperate with the charging lining and is matched in clearance.
But said double sealing comprises between inclined-plane and the feed pipe on the V-shaped groove pressure regulating cover of charging lining through the asbestos packing sealing, but and adopts the sealing ring sealing between the rectangular loop groove of pressure regulating cover and the feed pipe.
Between said charging lining step and feed pipe end face and the gap of feed pipe cylindrical and charging lining inner chamber parallel-segment all is not more than 10mm.
Multi-sealed groove and step and feed pipe discharge end by charging lining inner chamber of the present invention forms labyrinth seal, but but but connect with the charging lining through the adjustment bolt with sealing ring sealing pressure regulating cover between the feed pipe also can online adjustment crush for asbestos packing sealing between pressure regulating cover and charging lining and the feed pipe and pressure regulating cover.The charging lining is for optimizing structure, and the big end of inner chamber is a taper surface, and its inner chamber comprises a step and at least one groove, and forms labyrinth seal with feed pipe.The end face and the cylindrical gap that constitute between said charging lining step and the feed pipe are not more than 10mm.But the asbestos packing sealing can advance pressure regulating cover to compress asbestos packing assurance sealing by online continuous adjustment bolt, and adjustment amount is greater than 5mm.But pressure regulating cover is pressed into to cooperate with the charging lining and is matched in clearance; But pressure regulating cover is pressed into end face and offers an inclined-plane, the hole cannelure that to offer a cross section at least be rectangle within it, and the inclined-plane compresses asbestos packing, and rectangular channel indentation sealing circle has constituted the sealing ring sealing; But the gap is not more than 5mm between pressure regulating cover endoporus and the feed pipe.
Beneficial effect of the present invention: but the present invention has adopted the online adjustment of pressure regulating cover, can under the non-stop-machine situation of grinding machine, constantly compress asbestos packing and guarantee the charging sealing property; The big end of charging lining inner chamber is the labyrinth seal that forms between pyramidal structure and charging lining and the feed pipe among the present invention; Alleviated greatly and advanced the wearing and tearing of grind materials asbestos packing sealing and sealing ring sealing; The continuous online adjustment crush but asbestos packing sealing employing pressure regulating cover is in operation adds the sealing ring sealing, good seal performance; Its sealing replacement cycle is obviously elongated; Improved feed end greatly and sealed service life, made grinding machine, improved the production efficiency of grinding machine because of the shutdown number of times that the charging poor sealing causes obviously reduces.
