Description

The vane type discharge device of cement bag packer

The utility model relates to the discharge device in the cement bag packer, relates in particular to a kind of vane type pay-off of cement bag packer.

Vane type discharge device in the present cement bag packer, though the more spiral discharge device of its ash discharge amount is many, but because its impeller is made up of four mutually perpendicular blades usually, the ash chamber is straight barrel type again, so the eddy flow effect of grey indoor ash is bad, floatingization effect also a little less than, consequently operational throughput is few, can efficient is low.

The purpose of this utility model is to provide a kind of defeated ash big can efficient of amount high vane type pay-off.

The purpose of this utility model is to realize like this, a kind of vane type discharge device of cement bag packer, include electrical motor, belt pulley, belt, the ash chamber, impeller, antifriction-bearing box, axle, the antifriction-bearing box bearing, an end that wherein is arranged at the axle on the antifriction-bearing box is provided with belt pulley, the other end passes the wall of grey chamber to grey indoor, and this end is provided with an impeller, it is characterized in that an inclined angle alpha is arranged at bottom, grey chamber, 5 °＜α＜15 °, wide at the top and narrow at the bottom to form, on the end plate of lower end, grey chamber, be provided with a meniscus, leave clearance delta S between this meniscus periphery and circumference of impeller face; Impeller by wheel hub be connected it on have a radial β angle six thin type blades formed, this β angle is 10 ° of β≤30 °, stagger mutually with center, grey chamber in the impeller center, its distance is 50＜f＜150mm.

The utility model has the advantages that: the grey eddy flow in the grey chamber is effective, and speed is fast, floatingization is effective, and the ash discharge amount is big, and speed is fast, and stability is good.

Come structure of the present utility model is further narrated with drawings and Examples below.

Embodiment

Description of drawings

Fig. 3 is the A-A view of Fig. 2

By shown in Fig. 1～3 as seen, the vane type discharge device in the present embodiment includes electrical motor 1, grey chamber 2, impeller 3, antifriction-bearing box bearing 4, axle 5, drive pulley 6, belt 7, wherein:

2 bottoms, ash chamber become skewed, its leaning angle is α, α=10 °, wide at the top and narrow at the bottom to form, the end plate 21 of 2 lower ends, ash chamber is provided with a meniscus 23, it is 3＜Δ S＜5mm that the setting of this meniscus 23 should make the clearance delta S between its periphery and impeller 3 peripheries, and meniscus 23 is embedded in the rim of the mouth 11 of grey chamber by its bayonet socket 231 in the present embodiment.

Impeller 3 is arranged at the bottom of grey chamber 2 and is linked on the axle 5, impeller 3 is formed by wheel hub 31 with six 32 in slim blades that have radial β angle that screw is screwed together on the wheel hub 31, wherein the β angle is 20 °, and 0.2～0.3 of the length of blade 32 and impeller diameter, the setting of impeller should make its center and center, grey chamber stagger apart from f f=80mm.

Antifriction-bearing box bearing 4 in the present embodiment is by being made up of bearing 42, bearing cap shims 43 of one being linked to cantilevered bearing body 41 on 2 walls of grey chamber, be arranged in this bearing body 41, axle 5 runs through bearing body 41, and the one end worn in the ash entrance chamber 2 by the hole 12 of side, grey chamber, adorn a belt pulley 6 at the other end of 31 of the wheel hubs of this end device impeller of axle 5.

In the present embodiment, for the ash that makes grey chamber does not leak, 22 places, hole in grey chamber 2, be provided with one and be linked on the grey chamber 2 and be the base plate 25 of placing caulking gum 8 usefulness and the pinch device 24 of pinch-off seal rubber, this device 24 is made up of two bolts 241, pressing plate 242 and the hold-down nut 243 that are linked on the grey locular wall.

The pay-off of the foregoing description is because grey chamber lower tilt, six inclination β angle blades and set reverse link seal as structures such as glue the little gap that forms between impeller vane and grey chamber lower wall and the setting of staggering, the axial outlet at impeller center and center, grey chamber, make present embodiment send that apparatus for ash has that the ash discharge amount is big, speed fast, the advantage of good stability, no leak, long service life.

In addition, unimpeded in order to make ash hole, also the ash hole of grey chamber is designed to shape in the present embodiment, its center line of discharge and horizon are the ψ leaning angle, and this ψ angle is 3～5 °.

Also design one in addition in the present embodiment in bottom, grey chamber and pay grey chamber 9, the grey chamber 9 of this pair communicates with grey chamber 2 by the row of one on 2 rear walls of grey chamber sluice gate 26, its role is to drain the metal sundries that infiltrates in the ash discharge by the centrifugal action face, beat the damage blade and block impeller to exempt these metal sundries, thereby make the discharge operation safer, reliable.
