DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model.

[0030] Example:

[0031] As Figures 1-5The utility model provides a kind of fuel additive blending mixing device, including fixed tank 1, mixing assembly and separation component;Fixed tank 1 includes bolt connection's cover plate, cover plate is opened with feeding opening 2, and coaxially with annular separation groove 3 is opened in inner bottom side;Mixing assembly includes mixing tank 4 and mixing piece;Mixing tank 4 is located at the bottom end of fixed tank 1, and is supported by support leg 5;Mixing piece is located in mixing tank 4, for the raw material in mixing tank 4 is stirred;Separation component includes separation cylinder 6, separation pipe 7, feed pipe 8, separation valve 9, feed valve 10 and separation stirring piece 11;Several separation cylinder 6 circular array is located in fixed tank 1, and the upper end of separation cylinder 6 is provided with the opening located below feeding opening 2;Separation pipe 7 is communicated and located at the outer circumferential side of separation cylinder 6, and towards separation groove 3, for the raw material in separation cylinder 6 is guided to separation groove 3;Separation valve 9 is located on separation pipe 7;Feed pipe 8 is communicated and located in separation cylinder 6, for the raw material in separation cylinder 6 is introduced into mixing tank 4;Feed valve 10 is located on feed pipe 8;Separation stirring piece 11 is located in separation cylinder 6, and for the raw material in separation cylinder 6 is stirred;Separation valve 9, feed valve 10 are solenoid valve.

[0032] The principle and beneficial effects of the above technical solution are as follows:

[0033] By arranging the separation cylinders 6 in a circumferential array in the fixed tank 1 and respectively arranging independent separation valves 9 and feed valves 10 on each separation cylinder 6, the raw materials are first pretreated in the separation cylinders 6 before entering the mixing tank 4. When the raw materials are poured from the feeding opening 2, they first fall into the interior of the separation cylinders 6 and are preliminarily stirred by the separation stirring pieces 11.

[0034] If the pouring is correct, the feed valve 10 is controlled to open, so that the separation cylinder 6 is communicated with the mixing tank 4, the correct raw materials enter the mixing tank 4 through the feed pipe 8 and are finally stirred by the mixing piece, thereby completing the normal process of correct pouring.

[0035] However, when the pouring is incorrect, the conventional mixing device cannot prevent the raw materials from continuously entering the mixing tank 4, nor can it separately pour out the incorrectly poured raw materials, so that the mixture in the whole mixing tank 4 can only be completely scrapped. The present application realizes controllable switching of the flow direction of the raw materials through the separation valve 9: when the pouring is incorrect, the separation valve 9 is controlled to open, the incorrectly poured raw materials in the separation cylinder 6 directly enter the separation groove 3 at the bottom of the fixed tank 1 through the separation pipe 7, realizing independent collection of the incorrectly poured raw materials without mixing with other correct raw materials. In cooperation with the stirring of the separation stirring piece 11, the incorrectly poured raw materials can be accelerated to flow out along the separation pipe 7 and be collected in the separation groove 3, avoiding the situation that the whole mixture in the mixing device of the prior art is discarded due to incorrect pouring, and reducing the waste of raw materials.

[0036] In the embodiment, the outer bottom side of the fixed tank 1 is vertically provided with a recovery pipe 12 communicated to the separation groove 3; the recovery pipe 12 is used for guiding the raw materials in the separation groove 3 out.

[0037] Principles and beneficial effects of the above technical solutions:

[0038] The separation tank 3 is used to temporarily contain the incorrectly input raw materials, and the raw materials in the separation tank 3 will gradually accumulate as the separation operation proceeds. By arranging the recovery pipe 12 connected to the separation tank 3 on the outer bottom side of the fixed tank 1, when the raw materials in the separation tank 3 accumulate to a certain amount, they can be directly guided to the external container through the recovery pipe 12 for collection.

[0039] In this embodiment, the inner bottom side wall of the fixed tank 1 is coaxially rotatably provided with a separation shaft 14 by a first driving motor 13; the first driving motor 13 is a servo motor; an L-shaped pushing frame 15 is arranged on the separation shaft 14; the horizontal part of the pushing frame 15 is higher than the separation cylinder 6 to avoid collision with the separation cylinder 6 during rotation; the vertical part of the pushing frame 15 is in sliding contact with the inner circumferential side of the fixed tank 1, and the bottom end of the vertical part is slidingly arranged in the separation tank 3, for pushing the raw materials entering the separation tank 3 to the direction of the recovery pipe 12.

[0040] Principles and beneficial effects of the above technical solutions:

[0041] The separation tank 3 is located at the bottom of the fixed tank 1, and its structure is annular. The incorrectly input raw materials may accumulate at the bottom of the tank after falling in. By coaxially arranging a rotatable separation shaft 14 in the fixed tank 1 and fixing an L-shaped pushing frame 15 on the separation shaft 14, the pushing frame 15 can be rotated in the separation tank 3 under the drive of the first driving motor 13. The vertical part of the pushing frame 15 slides along the inner circumferential surface of the separation tank 3, and its bottom end closely abuts the bottom of the separation tank 3, so as to push the raw materials in the separation tank 3 to move in the direction of the recovery pipe 12, thereby accelerating the discharge of the raw materials in the separation tank 3. The horizontal part of the pushing frame 15 is higher than the upper part of the separation cylinder 6, so as to prevent interference with the separation cylinder 6 during rotation.

[0042] In this embodiment, the circumferential surface of the separation tank 3 close to the axis direction of the fixed tank 1 is a conical guide ring surface 16, which is used to guide the raw materials to flow downward and concentrate into the recovery pipe 12.

[0043] Principles and beneficial effects of the above technical solutions:

[0044] The side of the separation tank 3 close to the center of the fixed tank 1 is machined into a conical guide ring surface 16. The inverted conical surface can guide the raw materials entering the separation tank 3 to slide downward and outward by gravity, so as to automatically collect the raw materials to the bottom area of the separation tank 3 and further concentrate in the direction of the recovery pipe 12.

[0045] In the embodiment, the separating stirring part 11 comprises a stirring frame 17, a stirring shaft 18 and stirring bars 19; the stirring frame 17 is arranged at the inner circumferential side of the separating cylinder 6; the second driving motor 20, specifically a servo motor, is arranged on the stirring frame 17; the stirring shaft 18 is arranged on the power end of the second driving motor 20 and coaxial with the separating cylinder 6; and the stirring bars 19 are uniformly arranged at the circumferential side of the stirring shaft 18, and part of the stirring bars 19 are in sliding contact with the inner bottom wall of the separating cylinder 6.

[0046] Principles and beneficial effects of the above technical solutions:

[0047] The separating stirring part 11 is arranged in the separating cylinder 6 and rotates under the driving of the second driving motor 20; the stirring bars 19 stir the raw materials in the separating cylinder 6 so that the raw materials cannot be accumulated or agglomerated in the cylinder. Part of the stirring bars 19 are in sliding contact with the bottom wall of the separating cylinder 6, which can scrape the raw materials at the bottom to make the error raw materials flow into the separating tank 3 through the separating pipe 7 more quickly. At the same time, the stirring action can also accelerate the uniformity of the raw materials under the condition of correct feeding, and improve the mixing quality when the raw materials are added into the mixing tank 4.

[0048] In the embodiment, the mixing part comprises a third driving motor 21, a mixing shaft 22 and mixing bars 23; the third driving motor 21 is arranged on the inner top wall of the mixing tank 4; the mixing shaft 22 is arranged on the power end of the third driving motor 21 and coaxial with the mixing tank 4; and the mixing bars 23 are uniformly arranged at the circumferential side of the mixing shaft 22.

[0049] Principles and beneficial effects of the above technical solutions:

[0050] The mixing part is arranged in the mixing tank 4, the third driving motor 21 drives the mixing shaft 22 to rotate, and the mixing bars 23 form a strong stirring action in the mixing tank 4, so as to fully mix the correct raw materials and improve the uniformity and reaction efficiency of the mixing.

[0051] Part of the mixing bars 23 are in sliding contact with the bottom wall of the mixing tank 4, which can stir up the sediment at the bottom to avoid dead angles, ensure that there is no residual area in the mixing tank 4, and improve the uniformity of the mixing and the utilization rate of the raw materials.

[0052] In the embodiment, the outer circumferential side of the mixing tank 4 close to the bottom is communicated with a discharge pipe 24; the discharge pipe 24 is provided with a discharge valve 25, specifically an electromagnetic valve; and part of the mixing bars 23 are in sliding contact with the inner bottom wall of the mixing cylinder.

[0053] Principles and beneficial effects of the above technical solutions:

[0054] The outer circumferential side of the bottom of the mixing tank 4 is provided with the discharge pipe 24 and the discharge valve 25 matched with the discharge pipe 24, so as to realize the controllable discharge of the mixed raw materials.
