Abstract
A bottom charging and pressure reducing apparatus for a bucket elevator relates to the technical field of a bucket elevator, and comprises a main shaft, and a bushing, a bearing and a bearing cap arranged on the main shaft. The bottom charging and pressure reducing apparatus is also characterized by comprising an oil sealing sleeved over the main shaft at the bushing side, an oil sealing seat sleeved on the main shaft at the outside of the oil sealing, a back-up ring sleeved over the main shaft at the inner side of the bushing, an air valve connected with the bushing and situated above the main shaft, and an air pipe arranged above the air valve. The bottom charging and pressure reducing apparatus is reasonable in structure, tight in main shaft sealing, stable in operation, small in friction and long in service lifetime, and prevents leaking and overflowing of materials.
Description
Technical field:
The utility model relates to the bucket elevator technical field, specifically bucket elevator bottom feed and pressure purger.
Background technology:
It is large that bucket elevator has operational throughput, and hoisting depth is high, operates steadily reliable long remarkable advantage of life-span.Hopper from ladling out the following storage, along with load-transfer device or chain rise to the top, is walked around wheel backward lower upset in top to material, and bucket elevator is with in the material impouring dump tank.Driving band with the bucket elevator of transmission generally adopts rubber tape, be contained in down or the bend pulley of top driving drum and top and bottom on.The chain-drive bucket elevator generally is equipped with two parallel messenger chains, upper or below a pair of driving chain wheel is arranged, lower or above be a pair of changed course sprocket wheel.Bucket elevator holds the place that damageable place is the bucket elevator charging most, because main shaft seal is bad, easily leaks material, design unreasonablely, and causes the lifting flash serious without pressure purger promoting top, the bearing locking.Spindle abrasion is large, and because main shaft adding man-hour without due step, causes axially and collects together, causes maintenance frequent, and poor effect after the maintenance, is difficult to permanent use.
The utility model content:
Technical problem to be solved in the utility model is to provide a kind of rational in infrastructure, long service life, friction little, easy to maintenance, bucket elevator bottom feed and pressure purger that charging is effective.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
Bucket elevator bottom feed and pressure purger, comprise main shaft, be located at lining, bearing and bearing cap shim on the main shaft, it is characterized in that: also comprise being enclosed within the oil sealing that is positioned at the lining outside on the main shaft, be enclosed within the oil seal seat that is positioned at the oil sealing outside on the main shaft, be enclosed within the back-up ring that is positioned at the lining inboard on the main shaft, and be positioned at the valve that the top of main shaft is connected with lining, the top of valve is provided with tracheae.
Be connected by set screw between described oil seal seat and the lining.
Described lining is provided with the butter hole.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, main shaft seal is tight, operates steadily, and can not leak material and flash, rubs little long service life.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, bucket elevator bottom feed and pressure purger, comprise main shaft 1, be located at lining 2, bearing 3 and bearing cap shim 4 on the main shaft 1, also comprise being enclosed within the oil sealing 5 that is positioned at lining 2 outsides on the main shaft 1, be enclosed within the oil seal seat 6 that is positioned at oil sealing 5 outsides on the main shaft 1, be enclosed within the back-up ring 7 that is positioned at lining 2 inboards on the main shaft 1, and the valve 8 that is connected with lining 2 of the top that is positioned at main shaft 1, the top of valve 8 is provided with tracheae 9.Be connected by set screw 10 between oil seal seat 6 and the lining 2.Lining 2 is provided with butter hole 11.
The back-up ring 7 that the utility model installs additional can substitute the bearing step, so that bearing 3 and lining 3 etc. can axially not collected together; It is more closely knit that the oil seal seat 6 that installs additional and oil sealing 5 can make main shaft 1 be combined with casing, can not leak material; The pressure of generation when the valve 8 that installs additional is carried material to offset, what prevent from expecting overflows; The butter hole 11 that increases is convenient to oily to reduce friction.
Above demonstration and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
