DETAILED DESCRIPTION

[0032] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-4 In the first embodiment, an oil-immersed impurity removal device for bearing production and processing includes:

[0034] The filter box 30 has a box cover 32 at its upper end. The box cover 32 is connected to the discharge end of the oil immersion tank 10 via a butt joint 31 at a position corresponding to the front end of the filter box 30. The discharge end has a first valve 20.

[0035] A plurality of receiving hoppers 42 are respectively disposed on the lower end wall of the filter box 30, and the plurality of receiving hoppers 42 are arranged downwardly in an inclined manner, and a second valve 44 is provided on the discharge pipe of the receiving hopper 42;

[0036] A plurality of filter screens 40 are respectively fixedly connected to the plurality of filter screens 40, and the plurality of filter screens 40 are respectively located between the two receiving hoppers 42, and the meshes of the plurality of filter screens 40 gradually decrease from the front end to the rear end of the filter box 30;

[0037] A plurality of vibrators 48 are respectively fixedly connected to the plurality of filters 40;

[0038] The filter screen 40, the receiving hopper 42 and the inner wall of the filter box 30 form a filter chamber 47, and the inner wall of the filter box 30 and the filter screen 40 form a discharge chamber 47;

[0039] A mounting frame 64, fixedly connected to the filter box 30;

[0040] The centrifugal filter assembly 60 is disposed on a mounting frame 64;

[0041] The pump body 50 is fixedly connected to the outer wall of the filter box 30 . The pump body 50 is connected to the discharge chamber 47 through a suction pipe 51 and is connected to a centrifugal filter assembly 60 through a guide pipe 52 . The centrifugal filter assembly 60 is used to further filter the oil in the discharge chamber 47 .

[0042] This embodiment is implemented as follows:

[0043] When the present application is in use, the first valve 20 is opened, and the grease in the oil immersion pool 10 will enter the filter box 30 through the docking pipe 31, and then the grease will enter the filter chamber 41, and be filtered by the filter screen 40, leaving large particles of impurities in the receiving hopper 42. Since the mesh size of the filter screen 40 is gradually reduced, multiple filter screens 40 can filter the impurities in the grease in a hierarchical manner. Finally, the grease enters the discharge chamber 41, is sucked away by the pump body 50 through the suction pipe 51, and is introduced into the centrifugal filter assembly 60 through the guide pipe 52 to filter the oil, and the discharge pipe 43 on the receiving hopper 42 in the filter box 30 can discharge the impurities blocked in the filter chamber 41;

[0044] At the same time, the vibrator 48 can drive the filter screen 40 to vibrate, so that the impurities blocked on the filter screen 40 are shaken off.

[0045] The advantage of the present application over the prior art is that it can reduce the filtering burden of the filter 40 for filtering grease.

[0046] See also Figure 2 , an inclined baffle 45 is provided on the filter screen 40 to prevent the oil from directly impacting the filter screen 40;

[0047] The baffle 45 can prevent grease from directly impacting the filter 40 and prevent impurities from being stuck in the mesh.

[0048] See also Figure 2 , an inclined baffle 46 is fixedly connected to one side of the inner wall of the receiving hopper 42 close to the filter screen 40;

[0049] The barrier net 46 can reduce the impact of impurities entering the receiving hopper 42 on the filter net 40.

[0050] See also Figure 1 , 2 3. The centrifugal filter assembly 60 includes

[0051] The filter barrel 61 passes through the mounting frame 64 and is fixedly connected to the mounting frame 64 via the mounting plate 62. The upper end of the filter barrel 61 has the mounting frame 64.

[0057] The rotating rod 73 can drive the filter sleeve 70 and the material receiving box 71 to rotate through the connecting rod 72, and the guide pipe 52 introduces the grease into the filter sleeve 70. During the rotation of the filter sleeve 70, the grease can pass through the filter sleeve 70, so that the filter sleeve 70 blocks the impurities, thereby playing a role of centrifugal filtration. Due to the filtration through the filter box 30, the filtration burden of the filter sleeve 70 is greatly reduced, and the cleaning interval of the impurities in the filter sleeve 70 is also greatly improved.

[0058] See also Figure 2 , 3 The outer wall of the filter sleeve 70 is fixedly connected to the rotating ring 75 through a connecting plate 76, and the inner wall of the filter barrel 61 is fixedly connected to a guide rail 77 corresponding to the position of the rotating ring 75, and the rotating ring 75 is rotatably sleeved on the guide rail 77;

[0059] The filter sleeve 70 is connected to the rotating ring 75 through the connecting plate 76, and the rotating ring 75 and the guide rail 77 are rotated, so that the rotation stability of the filter sleeve 70 can be improved.
