[0027] The utility model provides Figure 1 - Figure 6A solid-liquid separation device for vegetable oil extraction is shown, and its basic structure mainly includes a filter shell 1, a filter mechanism 2 and a discharge pipe 3. The filter shell 1 is placed on the ground of the factory area, and the filter mechanism 2 is placed in the filter shell 1. The lower end surface of the filter shell 1 is connected to the discharge pipe 3 for discharging the filtered vegetable oil.

[0028] Example 1

[0029] On the above basic structure, the filter mechanism 2 includes a cylindrical inner filter body 21 and an outer filter body 22. The inner filter body 21 is placed in the outer filter body 22, and the outer surface of the inner filter body 21 is arranged to fit the inner surface of the outer filter body 22. The inner filter body 21 and the outer filter body 22 can rotate relative to each other.

[0030] The inner filter body 21 includes a support plate 211, a filter screen 212, and a bottom plate 213. The support plate 211 and the filter screen 212 are alternately connected in sequence to form a grid-shaped filter layer.

[0032] A steering mechanism 4 is provided between the inner filter body 21 and the outer filter body 22 to adjust or temporarily fix the relative position between the inner filter body 21 and the outer filter body 22. Specifically, the steering mechanism 4 includes a rotating block 41, a contact plate 42 and an electric telescopic rod 43. The top of the filter housing 1 is detachably connected with a cover, the cover is rotatably connected with a rotating block 41, the rotating block 41 is fixedly connected with the contact plate 42, the contact plate 42 is detachably connected with the side wall of the inner filter body 21, and the bottom of the bottom plate 1 213 is provided with an electric telescopic rod 43 wirelessly connected with an external controller. The electric telescopic rod 43 includes two sections, the first section is fixedly connected with the bottom plate 1 213, and the second section will be inserted into a card slot provided in the bottom plate 2 23 during the movement.

[0033] By disassembling and assembling the abutment plate 42, the purpose of filling the inner filter body 21 with vegetable oil can be achieved.

[0034] The user rotates the rotating block 41 to drive the inner filter body 21 to rotate in the outer filter body 22, and after the rotation is completed, the second section of the electric telescopic rod 43 is inserted into the corresponding slot. By inserting the electric telescopic rod 43 into different slots, the size of the through area between the filter screen 1 212 and the filter screen 2 222 can be changed, and the size of the filter hole can be further changed by stacking the filter screen 1 212 and the filter screen 2 222.

[0035] Therefore, how to design the position of the card slot requires the user to make a specific design according to the specific usage situation, and this embodiment will not be described in detail here.

[0036] The centrifugal motor 7 is a power element that drives the inner filter body 21 and the outer filter body 22 to rotate synchronously, so that the vegetable oil in the inner filter body 21 can improve the filtering effect under the action of centrifugal force. The centrifugal motor 7 is installed on the filter shell 1, and the output shaft of the centrifugal motor 7 is fixedly connected to the bottom plate 223. The bottom plate 223 drives the inner filter body 21 to rotate during filtering through the electric telescopic rod 43 and the card slot.

[0037] Example 2

[0038] On the above-mentioned basic mechanism, the filtering mechanism 2 includes an inner filter body 21 and an outer filter body 22, both of which are rectangular box-shaped. The inner filter body 21 is placed in the outer filter body 22, and the outer surface of the inner filter body 21 is arranged to fit the inner surface of the outer filter body 22. The inner filter body 21 and the outer filter body 22 can slide relative to each other.

[0039] The inner filter body 21 includes a support plate 211, a filter screen 212, and a bottom plate 213. The support plate 211 and the filter screen 212 are alternately connected in sequence to form a grid-shaped filter layer. The support plate 211 and the filter screen 212 are fixed to the bottom of the circular bottom plate 213.

[0040] The outer filter body 22 includes a second support plate 221 , a second filter screen 222 , and a second bottom plate 223 . The second support plate 221 and the second filter screen 222 are alternately connected in sequence to form a grid-shaped filter layer. The second support plate 221 and the second filter screen 222 are fixed to the bottom of the circular second bottom plate 223 .

[0041] A pushing mechanism 5 is arranged between the inner filter body 21 and the outer filter body 22, and the pushing mechanism 5 includes a pushing motor 51 and a screw rod 52. The pushing motor 51 is installed on the filter shell 1, and the output shaft of the pushing motor 51 is fixedly connected to the screw rod 52. The screw rod 52 penetrates the filter shell 1 and the outer filter body 22 and is threadedly connected to a support plate 211 in the inner filter body 21. The pushing motor 51 is electrically connected to an external controller.

[0042] The opposite surfaces of the bottom plate 1 213 and the bottom plate 223 are provided with embedding grooves, in which a plurality of balls are placed for rolling, so as to improve the smoothness of the inner filter body 21 and the outer filter body 22 when moving.

[0043] A pressing mechanism 6 is provided on the top of the filter shell 1, including a pressing plate 61 and a connecting rod 62. The connecting rod 62 is connected to the telescopic end of the cylinder, and the connecting rod 62 is slidably connected to a slide groove provided on the pressing plate 61. The pressing plate 61 is slidably connected up and down in the inner filter body 21.

[0044] The cylinder includes a cylinder body and a telescopic rod. The cylinder body is installed on the outside of the filter shell 1. The cylinder body and the telescopic rod are slidably connected. The telescopic rod and the connecting rod 62 are fixedly connected. A control unit for controlling the movement of the telescopic rod is arranged in the cylinder body. The control unit is electrically connected to an external controller.

[0045] When in use, the push motor 51 is turned on to drive the screw rod 52 to rotate forward and reverse, thereby driving the inner filter body 21 to move left and right in the outer filter body 22. When the inner filter body 21 and the outer filter body 22 move, the interlaced movement between the support plate 221, the filter screen 222, the support plate 1 211 and the filter screen 1 212 changes the size of the through area between the filter screen 222 and the filter screen 1 212, so as to achieve the purpose of adjustable filter hole gap.

[0046] The cylinder drives the connecting rod 62 downward by allowing the telescopic rod to move downward, and the connecting rod 62 drives the pressing plate 61 downward, forcing the filtrate in the inner filter body 21 to pass through the filter net for filtration as soon as possible. Even if the inner filter body 21 moves, the connecting rod 62 and the pressing plate 61 can still be squeezed and matched due to the existence of the slide groove.

[0047] The increased penetration area mentioned above means that the vegetable oil in the inner filter body 21 can move to the outer filter body 22 through the gap corresponding to the area. When the support plate 1 211 and the support plate 2 221 block each other or the filter screen 1 212 and the filter screen 2 222 overlap, the size of the penetration area can be changed.

[0048] In summary, the improvement of the utility model mainly lies in that the relative movement characteristics between the inner filter body 21 and the outer filter body 22 are utilized to change the gap size of the filter holes that can penetrate each other between the inner filter body 21 and the outer filter body 22, so as to adapt to the filtering requirements of different stages and different crude oils, thereby improving adaptability.

[0049] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
