Detailed Description

Referring to fig. 1 to 3, a centrifugal deoiling machine includes an outer barrel 1 and an inner barrel 2 having a plurality of through holes 22 distributed on a barrel wall, a support seat 11 is disposed in the outer barrel 1, the inner barrel 2 is mounted on the support seat 11, the support seat is connected to an output end of a motor, a slag discharge disc 21 is disposed on an outer wall of the inner barrel 2, and the slag discharge disc 21 is wound on an arc surface of an outer wall of the inner barrel 2 and gradually decreases from high to low according to a rotation direction of the inner barrel 2. The movable connection mode of the inner barrel 2 and the supporting seat 11 can be that the top of the supporting seat 11 is provided with a cross-shaped protrusion, and the bottom of the inner barrel 2 is provided with a corresponding concave position, so that the inner barrel 2 can be more conveniently placed on and taken out of the supporting seat 11.

The utility model discloses a centrifugal deoiling machine is equipped with row sediment video disc 21 outside interior bucket 2, at interior bucket 2 rotation in-process, impurity and the fines that are stained with oil on outer bucket 1 inner wall can be scraped to sediment video disc 21 after certain thickness, then attach on arranging sediment video disc 21, under high-speed rotation, impurity and the fines of being scraped by sediment video disc 21 can be followed and arrange sediment video disc 21 and slide down, consequently impurity and the fines on outer bucket 1 inner wall can not gather the bodiness and reach the outer wall of touching interior bucket 2, through-hole 22 can not be plugged up, make deoiling in-process centrifugal deoiling machine keep higher deoiling efficiency always.

In order to enable the impurities and fine scraps scraped by the slag discharge disk 21 to slide down along the slag discharge disk at high speed, the included angle between the slag discharge disk 21 and the horizontal plane is 45-75 degrees.

The width of the slag discharging disc 21 is smaller than the distance between the outer barrel 1 and the inner barrel 2, so that the slag discharging disc 21 is prevented from colliding with the inner wall of the outer barrel 1 due to unstable gravity center at the initial rotation stage of the inner barrel 2. Thus, a certain gap is left between the residue discharge disk 21 and the outer barrel 1, although the gap can accumulate impurities and fine debris, the residue discharge disk 21 can be scraped off as long as the residue discharge disk is thickened until the residue discharge disk touches the gap, and the residue discharge disk cannot be thickened to the outer wall of the inner barrel 2, so the deoiling efficiency cannot be influenced.

The included angle between the upward surface of the slag discharging disc 21 and the outer wall of the inner barrel 2 is smaller than the included angle between the downward surface of the slag discharging disc 21 and the outer wall of the inner barrel 2. The impurities and the fine dusts scraped by the slag discharge disk 21 tend to move downwards and also to the outside, and the impurities and the fine dusts are further prevented from returning to the inner tub 2.

The slag discharging discs 21 are less than four in total and are evenly distributed on the circumference by taking the rotating center of the inner barrel 2 as the center of a circle. The compact disc 21 increases friction, which is not conducive to the rapid sliding of impurities and fine particles.

The through hole 22 at the lowest position is flush with the bottom plate of the inner barrel 2, the outer wall of the inner barrel 2 extends downwards to be lower than the bottom plate to form an annular baffle plate 23, and the slag discharge disc 21 is arranged below the annular baffle plate 23. The impurities and the fine dusts which continuously slide downwards are gathered at the periphery of the ring-shaped baffle 23, and as long as the height of the ring-shaped baffle 23 is high enough, the impurities and the fine dusts cannot reach the bottom plate of the inner barrel 2.

The outer barrel 1 is provided with an outlet 12, and the outlet 12 and the bottom end of the slag discharge disk 21 are at the same height. The outlet 12 discharges oil, foreign substances and fine debris, which can be rapidly discharged out of the tub 1 with the aid of the residue discharge disk 21. The outlet 12 is connected with a filter screen 3 for receiving various substances, impurities and fine scraps are separated from the filter screen, oil drops downwards to realize separation, an oil groove 4 is formed below the filter screen 3, recovered oil is recycled, so that the impurities and the fine scraps in the working oil are only sourced from parts to be processed, and the impurities and the fine scraps in the working oil are prevented from being increased rapidly.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and decorations can be made without departing from the principle of the invention, and these modifications and decorations are also regarded as the protection scope of the present invention.
