Abstract
The utility model discloses a novel shaft end sealing structure of a carbon black feeding pump. The novel shaft end sealing structure of the carbon black feeding pump is positioned in a cylindrical structure of a pump end cover, wherein a partition plate is arranged inside the cylindrical structure; a bearing seat is arranged at the outer end of the partition plate; the shaft end sealing structure is arranged inside the partition plate; baseball-sized openings are formed in the top and the bottom of the cylindrical structure; wool felt blocks are added in two openings by hands and used for sealing the shaft end; however, since the wool felt blocks are difficultly pressed by the hands and the pump has inner pressure, thin and smooth carbon black powder is hardly stopped from overflowing outwards, thus causing environmental pollution easily. The novel shaft end sealing structure of the carbon black feeding pump adopts a mechanical pressing stuffing box structure which comprises a stuffing box, a stuffing pressing cover, a sealed stuffing, screw rods and nuts. The mechanical pressing stuffing box structure is characterized in that a cylindrical stuffing box is arranged in a shaft hole of the pump end cover; the stuffing box is full filled with the sealing stuffing; the sealing stuffing is pushed into the stuffing box by using the stuffing pressing cover; the sealing stuffing is pushed and compacted by using three screw rods and nuts which are mounted at the periphery of the stuffing box, so that sealing performance of the shaft end of the carbon black feeding pump is ensured.
Description
Technical field
The utility model relates to a kind of carbon black production equipment, especially carbon black feeding pump.
Background technique
Current carbon black feeding pump sealing structure of shaft end, is in two barrel-shaped structures, to have a dividing plate in barrel-shaped structure on the pump end cap of pump case both sides, and the outside of dividing plate is the bearing support of rotor shaft, and the inside of dividing plate is shaft end seal stuffing box; Known carbon black feeding pump sealing structure of shaft end, just refers to this piece barrel-shaped structure in the inside of dividing plate; This barrel-shaped structure have the opening of a baseball size, these two openings to be used for the free-hand stuffing box packing one wool felt piece that adds inside above and below to use, filled up wool felt piece and filled in to such an extent that be exactly tightlier for shaft end seal as far as possible; But free-hand interpolation wool felt piece can not squeeze very tightly wool felt piece, and pump has internal pressure, and these wool felt pieces substantially can't stop fine and smooth carbon black powder and outwards overflow, and therefore easily cause environmental pollution.
Summary of the invention
In order to change the problem of existing carbon black feeding pump sealing structure of shaft end poor sealing, the utility model proposes a solution: be exactly free-hand filled method, change the method that machinery promotes compacting filler into.
The utility model solves the technological scheme that its technical problem adopts: carbon black feeding pump Novel shaft-end sealing structure is by pump case, pump end cap, rotor shaft, synchromesh gear, stuffing box, Gland, stuffing box packing, screw rod, the formations such as nut; Novel shaft-end sealing structure is positioned at the barrel-shaped structure of the pump end cap of pump case both sides, in the middle of barrel-shaped structure, there is no dividing plate, bearing support outside, the inside is Novel shaft-end sealing structure, it is characterized in that: at the axis hole place of pump end cap, have a cylindrical pad box concentric with axis hole, in stuffing box, fill it up with stuffing box packing, with Gland, it is advanced in box, use three bolt and nuts that are arranged on stuffing box periphery stuffing box packing push-tight compacting.
The beneficial effects of the utility model are, with Gland, advance, and with three bolt and nuts pressurizations, can make stuffing box packing tightly crowded, and the sealing of carbon black feeding pump shaft end seal has just had assurance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the carbon black feeding pump general structure schematic diagram with Novel shaft-end sealing structure.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is Fig. 1 " I " partial enlarged drawing.
Fig. 4 is the B-B sectional view of Fig. 3.
In figure, 1. pump case, 2. pump end cap, 3. rotor shaft, 4. synchromesh gear, 5. Gland, 6. stuffing box packing, 7. screw rod, 8. nut, the barrel-shaped structure of M. pump end cap, W. stuffing box, three hand holes of K. on barrel-shaped structure.
Embodiment
In figure, carbon black feeding pump Novel shaft-end sealing structure, is positioned at barrel-shaped structure (M) inside of the pump end cap (2) of pump case (1) both sides, by stuffing box (W), Gland (5), stuffing box packing (6), screw rod (7), nut (8) forms; At the axis hole place of pump end cap, there is a cylindrical pad box (W) concentric with axis hole, at its three equally distributed screws of periphery processing, three screw rods (7) are installed; Gland (5) is enclosed within on three screw rods.On barrel-shaped structure (M), there are three hand holes (K) to face three screw rods, from three hand holes, put in three nuts of spanner rotation, compress filler or add filler operation.
