DETAILED DESCRIPTION

[0021] Example 1

[0022] As Figure 1As shown in the drawings, a centrifugal deoiling machine comprises a vertical outer cylinder 3, a vertical deoiling cylinder 2 rotatably connected in the outer cylinder 3, and a vertical pull rod 11 arranged in the deoiling cylinder 2. The pull rod 11 is vertically slidably connected with the deoiling cylinder 2. The bottom of the outer cylinder 3 is provided with a discharging hole 22. The bottom of the deoiling cylinder 2 is a horn shape with a large opening upward. The bottom of the outer cylinder 3 is a horn shape corresponding to the bottom of the deoiling cylinder 2. The bottom of the deoiling cylinder 2 is provided with a discharging port 13 at a position corresponding to the discharging hole 22. The deoiling cylinder 2 is provided with a conical plug 12 covering the discharging port 13. The plug 12 is fixedly connected with the pull rod 11. The sidewall of the deoiling cylinder 2 is uniformly provided with through holes. The inner bottom of the outer cylinder 3 is provided with an oil collecting groove 23. The bottom of the outer cylinder 3 is fixedly provided with an oil discharge pipe 1 in communication with the oil collecting groove 23. The outer cylinder 3 is provided with a motor 10 for driving the deoiling cylinder 2 to rotate. The top of the outer cylinder 3 is fixedly provided with an inclined feeding groove 5. The lowest part of the feeding groove 5 is located above the deoiling cylinder 2. The outer cylinder 3 is fixedly connected with four supporting legs at the lower part of the outer circle.

[0023] The working process of the utility model is as follows:

[0024] Firstly, the crushed filter core debris is added into the deoiling cylinder 2 through the feeding groove 5. Then the motor 10 is started. The motor 10 drives the deoiling cylinder 2 to rotate. Under the action of centrifugal force, the oil in the debris is thrown to the inner wall of the outer cylinder 3 through the through holes on the deoiling cylinder 2, and then is collected into the oil collecting groove 23 under the action of gravity, and then is discharged through the oil discharge pipe 1.

[0025] After the deoiling is completed, the motor 10 stops running, and the deoiling cylinder 2 also stops rotating. The pull rod 11 is pulled upward, so that the plug 12 is separated from the discharging port 13. The deoiled debris in the deoiling cylinder 2 falls down from the discharging hole 22 under the action of gravity through the gap between the plug 12 and the deoiling cylinder 2.

[0026] When the material is added into the deoiling cylinder 2 or the material in the deoiling cylinder 2 is discharged, the deoiling cylinder 2 does not need to be taken out, so that the working efficiency of the utility model can be improved.

[0027] Example 2

[0028] In combination with Figure 2 and Figure 3 the difference between the embodiment and example 1 is that:

[0029] The outer cylinder 3 top center fixed connection has vertical installation cylinder 4, the installation cylinder 4 center is equipped with vertical first bearing seat 8, the first bearing seat 8 is fixedly connected with installation cylinder 4 through three rib plates 21 along its circumferential direction, the first bearing seat 8 is vertically through the setting of rotating sleeve 7, the rotating sleeve 7 and first bearing seat 8 are rotatably connected by two disc angular contact ball bearings. The rotating sleeve 7 is drivingly connected with the motor 10, the rotating sleeve 7 is fixedly connected with the oil removal cylinder 2 through two layers of connecting rods arranged below the first bearing seat 8, the number of each layer of connecting rod is three, which are uniformly distributed along the circumferential direction of the rotating sleeve 7. The pull rod 11 is slidably connected with the rotating sleeve 7 through the sliding key.

[0030] When the rotating sleeve 7 drives the oil removal cylinder 2 to rotate, it also drives the pull rod 11 to rotate synchronously with the rotating sleeve 7, so that the pull rod 11 rotates synchronously with the rotating sleeve 7, and the blocking cover 12 rotates synchronously with the oil removal cylinder 2, thereby avoiding the relative sliding between the blocking cover 12 and the oil removal cylinder 2 when the blocking cover 12 covers the discharge port 13, which can prevent the blocking cover 12 or the oil removal cylinder 2 from being damaged.

[0031] Example 3

[0032] The difference between this embodiment and example 2 is that:

[0033] The top of the rotating sleeve 7 is fixedly connected with a driven pulley, the output shaft of the motor 10 is fixedly connected with a driving pulley, and the driven pulley and the driving pulley are drivingly connected through a V-belt.

[0034] The top of the outer cylinder 3 is provided with a lifting device 6, the lifting device 6 includes a shroud 14 covering the driving pulley, the bottom of the shroud 14 is fixedly connected with three rib plates 21, and the right part of the shroud 14 is provided with a window corresponding to the V-belt for the V-belt to pass through. The top of the shroud 14 is fixedly connected with a cylindrical support tube 18, the support tube 18 is provided with a second bearing seat 15 with a vertical axis, the support tube 18 is provided with a vertical sliding groove, and the circumference of the second bearing seat 15 is provided with a sliding block which can slide in the sliding groove. The support tube 18 and the second bearing seat 15 are vertically slidably connected through the sliding groove and the sliding block. The top end of the pull rod 11 is fixedly connected with a connecting sleeve 16 through a nut, the connecting sleeve 16 is rotatably connected with the second bearing seat 15 through two disc thrust bearings 17, and the support tube 18 is provided with a driving unit for driving the second bearing seat 15 to move up and down.

[0035] The driving unit includes a winch 20 driven by a motor fixedly connected to the top of the support tube 18, and the second bearing seat 15 is provided with a steel wire rope 19 fixedly connected to the lower end thereof. The lower end of the steel wire rope 19 is divided into two strands, which are respectively and symmetrically fixedly connected to the top of the second bearing seat 15, and the upper end of the steel wire rope 19 is wound around the drum of the winch 20.

[0036] When the winch 20 is running forward, the second bearing seat 15 is pulled upward by the steel wire rope 19, so that the pull rod 11 is moved upward, and the plug cover 12 is separated from the oil discharge cylinder 2, and the discharged debris in the oil discharge cylinder 2 is discharged. When the winch 20 is running reversely, the plug cover 12 is re-plugged on the discharge port 13 under the action of gravity. Since the second bearing seat 15 does not rotate with the pull rod 11 when moving vertically, the steel wire rope 19 is prevented from being twisted and unable to work normally. In addition, the above process does not require manual intervention, which can further improve work efficiency and reduce labor intensity.

[0037] The bottom edge of the outer cylinder 3 is turned up to form a 45° annular flange 24, and the oil collecting groove 23 is located on the inner side of the flange 24.

[0038] The oil discharged from the oil discharge cylinder 2 finally collects in the oil collecting groove 23 on the inner side of the flange 24, and the cross section of the oil collecting groove 23 is V-shaped, which can reduce the residual amount of oil in the oil collecting groove 23.

[0039] The above-described embodiments are more detailed and specific, express the preferred embodiments of the present application, and are only used to illustrate the technical ideas and characteristics of the present application. The purpose is to enable those skilled in the art to understand the content of the present application and implement it, but it is not limited to the present application, and the patent range of the present application cannot be limited to the present embodiment. That is, any equivalent changes or modifications made according to the spirit disclosed by the present application, without departing from the structure of the present application, the internal improvement of the system and the change between the subsystems, the transformation, etc. are still within the patent range of the present application.
