DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in the present embodiment, a filtering device for extracting plant essential oils comprises a filter box 1, a feed pipe 3 and a discharge pipe 4, a feed tank 2 is arranged on one side of the filter box 1, the feed pipe 3 is fixedly connected between the filter box 1 and the feed tank 2, the discharge pipe 4 is fixedly connected on one side of the filter box 1, a mounting plate 7 is slidably connected inside the filter box 1, a filter plate 5 is arranged inside the mounting plate 7, a fixed block 8 is fixedly connected on one side of the filter box 1, a limiting mechanism is arranged inside the fixed block 8, a displacement plate 9 is slidably connected inside the filter box 1, a pressing plate 10 is fixedly connected to the bottom of the displacement plate 9, and a displacement mechanism is arranged on the top of the filter box 1.

[0022] First, the material passes through the feed pipe 3 at the bottom of the feed tank 2 to the top of the filter plate 5 inside the filter box 1, and then the material is filtered by the filter plate 5. At this time, the displacement mechanism is started to drive the displacement plate 9 to move and at the same time drive the pressure plate 10 to approach the top of the filter plate 5, thereby squeezing the material on the top of the filter plate 5. This increases the filtration efficiency and does not cause the problem of tiny impurities being mixed into the filtrate, thereby increasing the practicality of the device. The filtered liquid is then discharged through the discharge pipe 4, and then when cleaning the debris remaining on the top of the filter plate 5, the fixing of the mounting plate 7 is released by toggling the limit mechanism, and then the mounting plate 7 is pulled to drive the filter plate 5 to detach from the inside of the filter box 1, and then the filter plate 5 is cleaned, thereby increasing the convenience of cleaning the device.

[0023] like Figure 1-Figure 4 As shown, the displacement mechanism includes two vertical plates 13, which are fixedly connected to the top of the filter box 1, a sliding rod 15 is fixedly connected between the two vertical plates 13, and a displacement block 14 is slidably connected to the outer side of the sliding rod 15. The displacement mechanism also includes a cylinder 16, which is fixedly installed on the top of the filter box 1, and one end of the movable rod of the cylinder 16 is fixedly connected to one side of the displacement block 14. A displacement groove 11 is opened inside the displacement plate 9, and a displacement rod 12 is slidably connected inside the displacement groove 11, and one end of the displacement rod 12 is fixedly connected to one side of the displacement block 14.

[0024] When extrusion is performed, the movable rod of the cylinder 16 is started to move, driving the displacement block 14 to move on the outside of the slide rod 15, so that the movement of the displacement block 14 can be limited by the slide rod 15 to prevent its movement from being offset. Then the displacement block 14 moves and drives the displacement rod 12 to slide inside the displacement groove 11, thereby driving the displacement plate 9 to move and driving the pressure plate 10 to move toward the direction of the filter plate 5, which can increase the filtration efficiency and thus increase the practicality of the device.

[0025] like Figure 1-Figure 4 As shown, the limiting mechanism includes a slide groove 17, which is opened inside the fixed block 8, and a slider 18 is slidably connected inside the slide groove 17, and a spring 20 is fixedly connected between the top of the slider 18 and the inner wall of the slide groove 17. The limiting mechanism also includes a clamping block 19, which is slidably connected inside the fixed block 8, and the top of the clamping block 19 is fixedly connected to the bottom of the slider 18. A clamping groove 6 is opened on the top of the mounting plate 7, and one end of the clamping block 19 extends to the inside of the clamping groove 6. A limiting groove 21 is opened on one side of the fixed block 8, and a lever 22 is slidably connected inside the limiting groove 21, and one end of the lever 22 is fixedly connected to one side of the slider 18.

[0026] When cleaning the filter plate 5, the lever 22 is moved inside the limit groove 21 and the slider 18 is driven to slide inside the slide groove 17, and then the block 19 is driven to disengage from the inside of the slot 6, thereby releasing the fixation of the mounting plate 7, and then the filter plate 5 is driven to disengage from the inside of the filter box 1 by pulling the handle of the mounting plate 7, and then the filter plate 5 can be cleaned, and then when installing the filter plate 5, one side of the mounting plate 7 contacts the inclined surface of the block 19, thereby driving the block 19 to move and the slider 18 to move to compress the spring 20, and when the slot 6 moves to one side of the block 19, the block 19 is driven to enter the inside of the slot 6 under the reaction force of the spring 20, thereby completing the installation of the filter plate 5, thereby increasing the practicality of the device.

[0027] The utility model provides a filtering device for extracting plant essential oils, and the specific working principle is as follows: first, the material passes through the feed pipe 3 at the bottom of the feed tank 2 to the top of the filter plate 5 inside the filter box 1, and then the material is filtered through the filter plate 5. At this time, the movable rod of the cylinder 16 is started to move and drive the displacement block 14 to move on the outside of the slide rod 15, so that the movement of the displacement block 14 can be limited by the slide rod 15 to avoid its movement from being offset. Then the displacement block 14 moves and drives the displacement rod 12 to slide inside the displacement groove 11, thereby driving the displacement plate 9 to move and driving the pressing plate 10 to approach the direction of the filter plate 5 at the same time, so as to increase the filtering efficiency. Then, the filtered liquid is discharged through the discharge pipe 4, and then the debris remaining on the top of the filter plate 5 is filtered. When cleaning the slag, the lever 22 is moved inside the limit groove 21 and the slider 18 is driven to slide inside the slide groove 17, and then the block 19 is driven to disengage from the inside of the groove 6, thereby releasing the fixation of the mounting plate 7, and then the filter plate 5 is driven to disengage from the inside of the filter box 1 by pulling the handle of the mounting plate 7, and then the filter plate 5 can be cleaned, and then when installing the filter plate 5, one side of the mounting plate 7 is in contact with the inclined surface of the block 19, thereby driving the block 19 to move and the slider 18 to move to compress the spring 20, and when the groove 6 moves to one side of the block 19, the block 19 is driven to enter the inside of the groove 6 under the reaction force of the spring 20, thereby completing the installation of the filter plate 5, thereby increasing the practicality of the device.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
