Abstract
The invention discloses a main shaft sealing device of a spiral conveyer, belonging to the technical field of conveyers. The main shaft sealing device of the spiral conveyer comprises a flange plate, a main shaft, a seat cover, a first sealing ring, a second sealing ring, a packing, a press cover, a spring, a spring seat, a nut and a screw rod, wherein the first sealing ring and the second sealing ring are sequentially sleeved on the outer wall of the main shaft; the packing is sleeved on the outer wall of the main shaft and outside the second sealing ring; the seat cover is fixed on the flange plate and sleeved on the outer wall of the main shaft and the outer wall of the packing; the press cover is sleeved on the outer wall of the main shaft and pressed outside the packing; the screw rod is fixed on the flange plate and passes through a hole in the seat cover; the screw rod is sleeved with the spring and the spring seat; and the press cover is fixed by using the nut. The main shaft sealing device of the spiral conveyer has the beneficial effect that a better sealing effect is realized, the maintenance times of the main shaft are reduced, the abrasion of the main shaft is decreased, and the service life of the main shaft is prolonged.
Description
Technical field
The present invention relates to a kind of screw conveyor product, relate in particular to a kind of screw conveyor main shaft sealing device, belong to the screw conveyor technical field.
Background technique
Screw conveyor is a kind of conveying equipment that is widely used in products such as coal, food, chemical industry, agricultural products, the main shaft of screw conveyor is when rotating, need very strong sealing, not so in the process of work, the sealing of spindles device can become flexible, can constantly there be material from the slit of main shaft, to overflow wear spindle.Traditional main shaft sealing device is simply to seal up with packing and gland at main-axis end, in gland external application bolt, can cause bolt looseness for a long time between the work, and then the main shaft seal effect weakens, and causes maintenance times to increase.
Summary of the invention
Problem at above-mentioned prior art exists the invention provides a kind of screw conveyor main shaft sealing device, has better sealing effect, reduces the main shaft maintenance times, reduces the main shaft wearing and tearing, prolongs main shaft working life.
To achieve these goals, the technical solution used in the present invention is: a kind of screw conveyor main shaft sealing device, comprise flange plate and main shaft, also comprise cover for seat, seal ring one, seal ring two, packing, gland, spring, spring seat, nut and screw rod, seal ring one and seal ring two are enclosed within spindle outer wall successively, seal ring two outer walls have oil groove, packing is enclosed within spindle outer wall and in seal ring two outsides, cover for seat is fixed on the flange plate and is enclosed within spindle outer wall and the outer wall of packing, the oil groove that the cover for seat outer wall has an oil hole and oil hole and seal ring two communicates, gland is placed on the spindle outer wall and is pressed in the packing outside, screw rod is fixed on the flange plate and passes hole on the cover for seat, is with spring and spring seat and fixes gland with nut on screw rod.
What be injected into seal ring two outer wall oil grooves by oil hole is butter.
Packing has three, and three packings are arranged side by side.
Cover for seat has two holes, is passed by two screw rods respectively.
Spring seat is provided with a groove.
Screw rod is to be welded on the flange plate.
Cover for seat is to be fixed on the flange plate with bolt and packing ring.
The invention has the beneficial effects as follows: have better sealing effect, reduce the main shaft maintenance times, reduce the main shaft wearing and tearing, prolong main shaft working life.
