[0028] like Figure 1-2As shown, the present application provides an emulsion filtering device, including a filter box 1, a liquid inlet 2 is provided on the top of the filter box 1, a liquid outlet 3 is provided on the bottom of the filter box 1, a filter frame 4 is provided in the filter box 1 in a pull-out manner, a magnetic filter assembly 5 and a sieve plate filter assembly 6 are provided on the filter frame 4, so that the filter frame 4 can be easily taken out of the filter box 1, and the magnetic filter assembly 5 and the sieve plate filter assembly 6 can be easily cleaned. When in use, the emulsion return liquid pipeline is connected to the liquid inlet 2 of the filter box 1. After the emulsion enters the filter box 1, it passes through the magnetic filter assembly 5 and the sieve plate filter assembly 6 from left to right in turn, and the metal chips in the emulsion are adsorbed and filtered by the magnetic filter assembly 5, and then pass through the sieve plate filter assembly 6. Filter other solid particle impurities in the emulsion to ensure the safe operation of the hydraulic support and other fluid supply equipment in the comprehensive mining working face. The magnetic filter component 5 includes a magnetic sheet 51 and a filter plate 52. The magnetic sheet 51 is fixedly arranged on the filter frame 4 at an angle. The filter plate 52 is fixedly arranged on the filter frame 4 and the side of the filter plate 52 close to the magnetic sheet 51 abuts against the lower end of the magnetic sheet 51. When the emulsion passes through the magnetic filter component 5, it flows downward along the inclined magnetic sheet 51 through the filter plate 52. The metal chips in the emulsion are attracted by the magnetic sheet 51, and other solid particle impurities in the emulsion will be preliminarily filtered by the filter plate 52, and then further filtered by the sieve plate filter component 6, thereby effectively improving the filtering effect.

[0029] like Figure 2-3 As shown, the sieve plate filter assembly 6 includes a filter sieve plate 61, a first support member 62 and a second support member 63. The filter sieve plate 61 is tilted, and the first support member 62 and the second support member 63 are respectively arranged at both ends of the filter sieve plate 61. The upper end of the filter sieve plate 61 abuts against the bottom of the filter plate 52. The emulsion filtered by the magnetic filter assembly 5 falls onto the tilted filter sieve plate 61. Other solid particles in the emulsion are separated from the emulsion through further filtration by the filter sieve plate 61. The clean emulsion passes through the filter sieve plate 61 and is discharged from the liquid outlet 3 at the bottom of the filter box 1. The filter aperture of the filter sieve plate 61 is smaller than the filter aperture of the filter plate 52 to achieve a better filtering effect.

[0030] like Figure 2 As shown, a guide plate 7 is fixedly provided obliquely in the filter box 1, and the guide plate 7 is located between the liquid inlet 2 and the upper end of the magnetic sheet 51. In this embodiment, the emulsion entering the filter box 1 is guided by the guide plate 7, so that the emulsion is dispersed and falls on the magnetic sheet 51, thereby increasing the contact area with the magnetic sheet 51 and improving the adsorption effect of the magnetic sheet 51 on the metal chips in the emulsion. The guide plate 7 can buffer the emulsion entering the filter box 1 to prevent the emulsion from directly impacting the magnetic sheet 51, thereby extending the service life of the magnetic sheet 51, and can also prevent the emulsion from having a large impact on the magnetic sheet 51 and washing away the metal chips adsorbed on the magnetic sheet 51.

[0031] like Figure 2 As shown, a plurality of support rods 8 are fixedly provided on the filter frame 4, and the support rods 8 are evenly arranged at the bottom of the magnetic sheet 51. In this embodiment, three support rods 8 are arranged, and the magnetic sheet 51 is supported by the support rods 8 to make the magnetic sheet 51 more stable.

[0032] like Figure 2-3 As shown, a handle 9 is fixedly provided on the filter frame 4 , and the handle 9 is located outside the filter box 1 . The handle 9 is used to facilitate pulling the filter frame 4 out of or inserting it into the filter box 1 .

[0033] like Figure 2 As shown, a support bar 10 acting on the filter frame 4 is fixedly provided on the inner wall of the filter box 1, and the support bar 10 abuts against the bottom of the filter frame 4 to stabilize the filter frame 4. In this embodiment, support bars 10 are fixedly provided on the front and rear inner walls of the filter box 1, and the tops of the two support bars 10 are flush.

[0034] like Figure 1-2 As shown, a transparent observation window 11 is provided on the top of the filter box 1, through which the metal chips adsorbed on the magnetic sheet 51 and other solid particles filtered by the filter screen plate 61 can be easily observed, so that the user can conveniently pull out the filter frame 4 from the filter box 1 according to actual needs, and clean the metal chips adsorbed on the magnetic sheet 51 and other solid particles filtered by the filter screen plate 61.

[0035] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
